Abstract
A pressure gauge type weighing device for hydraulic static pile presses comprises four pressure gauges. The four pressure gauges are respectively connected with rodless cavities of four support leg cylinders of a hydraulic static pile press by different pipelines. The pressure gauge type weighing device is simple in structure and convenient in operation, can accurately obtain the dead weight of the hydraulic static pile press only by the aid of the pressure gauges, and is accurate in weighing and small in error, and people can clearly determine whether balance weights are sufficient when the balance weights are added. In addition, the weight of the hydraulic static pile press can be accurately adjusted to assuredly avoid press floatation and eliminate potential safety hazards.
Description
Technical field
The utility model relates to a kind of weighing device, especially relates to a kind of hydraulic static pile pressing machine manometer type 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 preformed pile is pressed in the ground, and therefore, the hydraulic static pile pressing machine gross weight must could be pressed into preformed pile in the ground greater than pile driving pressure.The hydraulic static pile pressing machine gross weight 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 gross weight 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 gross weight 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 gross weight, 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 load increases, and the increase frequency of machine accident takes place to fall into.And when hydraulic static pile pressing machine gross weight during, can float machine,, have potential safety hazard toward major accident occurring less than pile driving pressure.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of mechanism simple, easy to operate, the accurate hydraulic static pile pressing machine manometer type weighing device of weighing.
The technical solution of the utility model is: a kind of hydraulic static pile pressing machine manometer type weighing device, comprise 4 pressure meters, and 4 pressure meters link to each other with the rodless cavity of 4 support oil cylinders of hydraulic static pile pressing machine respectively by different pipelines.
The utility model operating principle 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 pressure meter.
The utility model is simple in structure, and is easy to operate, just can accurately draw the hydraulic static pile pressing machine deadweight by pressure meter, 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 the utility model example structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises pressure meter I 1-1, pressure meter II 1-2, pressure meter III 1-3, pressure meter IV 1-4, pressure meter 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, pressure meter 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, pressure meter 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 pressure meter 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 utility model course of work 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 pressure meter, can accurately draw pile press weight according to formula G=Σ.Add balancing weight to the weight that requires according to the piling needs.According to pile press weight, regulate the main pressurized overflow valve and the secondary pressurized overflow valve of hydraulic static pile pressing machine, make pile press 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 pressure meter, can prevent floating machine.
