Abstract
A weighing device of a hydraulic static pile driver comprises four pressure gauges respectively connected with rodless cavities of four branch leg oil cylinders of the hydraulic static pile driver. The weighing device of the hydraulic static pile driver is simple in structure and convenient in operation, and can accurately weigh dead weight of the hydraulic static pile driver by the pressure gauges, wherein weighing error is small; while adding weight stacks, whether the weight stacks are enough is clear at a glance; weight can be accurately adjusted to prevent machine floatation accidents, so that potential safety hazard is eliminated.
Description
Technical field
The present invention relates to a kind of weighing device, especially relate to a kind of hydraulic static pile pressing machine weighing device.
Background technology
Hydraulic static pile pressing machine is a kind of equipment that is widely used in pile foundation construction.Hydraulic static pile pressing machine relies on gravity, by oil cylinder prefabricated pile is pressed in the ground, and therefore, the hydraulic static pile pressing machine general assembly (TW) must could be pressed into prefabricated pile in the ground greater than pile driving pressure.The hydraulic static pile pressing machine general assembly (TW) equals the main frame own wt and adds balancing weight weight.Because different geological conditions is different with the pile driving pressure that different stake types needs, at this moment, need the corresponding counterweight of stack could realize piling.Existing hydraulic static pile pressing machine self does not have function of weighing, need could release the pile press machine general assembly (TW) to main frame weight and the addition of balancing weight weight.The weight that provides because of main frame producer is theoretical weight, and main frame inside causes weight uncontrollable because of irritating reasons such as sand, and general theory weight and actual weight can exist than big difference; And stake machine balancing weight manufacturer very different because of qualification causes the weight of balancing weight to have bigger randomness especially.Therefore, the general assembly (TW) of extrapolating is also inaccurate, and error is bigger.During piling, if floating machine accident less than pile driving pressure, can take place the hydraulic static pile pressing machine general assembly (TW), realize piling so can only add balancing weight during piling as far as possible, like this, the use of a large amount of balancing weights, cause construction cost to increase, the pile press machine load increases, and the increase frequency of machine accident takes place to fall into.And when hydraulic static pile pressing machine general assembly (TW) during, can float machine,, have potential safety hazard toward major accident occurring less than pile driving pressure.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, it is simple to the invention provides a kind of mechanism, easy to operate, the accurate hydraulic static pile pressing machine weighing device of weighing.
Technical scheme of the present invention is: a kind of hydraulic static pile pressing machine weighing device, comprise 4 tensimeters, and 4 tensimeters link to each other with the rodless cavity of 4 support oil cylinders of hydraulic static pile pressing machine respectively by different pipelines.
Principle of work of the present invention is: (P * S), in the formula, G is the deadweight of stake machine according to formula G=Σ, S is the support oil cylinder piston area, P is a support oil cylinder pressure, can accurately draw a machine weight by the support oil cylinder pressure P, and the support oil cylinder pressure P can accurately be read by tensimeter.
The present invention is simple in structure, and is easy to operate, just can accurately draw the hydraulic static pile pressing machine deadweight by tensimeter, weighs accurately, and error is little; When adding balancing weight, whether balancing weight is enough, comes into plain view; Weight can accurately be adjusted, and guarantees can not occur floating machine accident, has eliminated potential safety hazard.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises tensimeter I 1-1, tensimeter II 1-2, tensimeter III 1-3, tensimeter IV 1-4, tensimeter I 1-1 links to each other with the support oil cylinder I 3-1 rodless cavity of hydraulic static pile pressing machine by pipeline I 2-1, tensimeter II 1-2 links to each other with the support oil cylinder II 3-2 rodless cavity of hydraulic static pile pressing machine by pipeline II 2-2, tensimeter III 1-3 links to each other with the support oil cylinder III 3-3 rodless cavity of hydraulic static pile pressing machine by pipeline III 2-3, and tensimeter IV 1-4 links to each other with the support oil cylinder IV 3-4 rodless cavity of hydraulic static pile pressing machine by pipeline IV 2-4.
The course of work of the present invention is as follows: hydraulic static pile pressing machine is supported by 4 support oil cylinders.(P * S), wherein, G is the deadweight of stake machine, and S is the support oil cylinder piston area, and P is a support oil cylinder pressure, reads the support oil cylinder pressure P by tensimeter, can accurately draw pile press machine weight according to formula G=Σ.Add balancing weight to the weight that requires according to the piling needs.According to pile press machine weight, regulate the main pressurized overflow valve and the secondary pressurized overflow valve of hydraulic static pile pressing machine, make pile press machine weight greater than pile driving pressure, like this, just can effectively avoid occurring floating machine phenomenon.Along with the increasing of pile driving pressure, respective leg pressure reduces, and can also judge whether the machine that can float by observing tensimeter, can prevent floating machine.
