Description

Pile pressing machine

Technical Field

The utility model relates to the field of constructional engineering equipment, in particular to a pile pressing machine.

Background

After the building is built, the conditions of subsidence of the indoor ground of the building often occur due to foundation subsidence and the like, but because the indoor floor height of a general building is limited, large equipment cannot be adopted to form piles indoors, meanwhile, the column position space of the building is larger, no counter force can be used for making small anchor rod static pressure piles, and the piles are difficult to press, so that the indoor ground of the building is difficult to be reinforced after subsidence, the danger is high, the time is long, the whole building is easy to be forced to be stopped, and the economic loss is also great.

Patent CN201620756445.7, prior to the applicant, discloses an integral pile press comprising: an upper bracket; a base; a support rod arranged between the upper bracket and the base; an integrated clamp movable up and down along the strut for clamping a pile body in operation, the integrated clamp comprising: the hollow chuck body is sequentially and uniformly provided with a plurality of chambers along the inner side of the chuck body, and clamping assemblies are arranged in the chambers; and the pile pressing oil cylinder is arranged between the upper bracket and the integral chuck and is used for pressing the clamped pile body into the foundation in operation.

Patent CN201920337492.1, prior to the applicant, improved on the basis of CN 201620756445.7: the pile pressing cylinder body is arranged on the cross beam, and the piston rod penetrates through the downward pile pressing from the cross beam, so that the overall height of the frame of the pile pressing machine is reduced, and the dumping risk is reduced.

The patent is a further improvement made on the basis of the patent CN201920337492.1, mainly improves the clamping assembly part in the chuck, simplifies the internal structure of the chuck and reduces the processing and manufacturing cost.

Disclosure of Invention

According to the pile driver, the clamping assembly in the clamping head is improved, the structure of the clamping head is simplified, and the processing and manufacturing cost is reduced.

Pile driver comprising: a frame, the frame comprising: the base, locate the guide arm on the base, and locate the crossbeam on the guide arm; the clamping head can move up and down along the guide rod, is positioned below the cross beam and is used for clamping the pile body in operation, and the clamping head is of a hollow structure and has an inclined surface on the inner wall; the inclined block is arranged in the chuck and is matched with the inclined plane, the inclined block is driven by a first oil cylinder, and the first oil cylinder is fixedly connected with the chuck; pile pressing oil cylinder, this pile pressing oil cylinder includes: the cylinder barrel is fixedly arranged on the cross beam, the piston rod can penetrate through the cross beam to move up and down, and the piston rod pushes the chuck to move up and down along the guide rod.

Further, the inclined block comprises two blocks which are symmetrically arranged.

Further, the first oil cylinder is fixedly connected with the clamping head through a connecting plate.

Further, a piston rod of the first oil cylinder is fixedly connected with the inclined block.

Compared with the prior art, the utility model has the beneficial effects that:

1. the pile body is clamped by the inclined blocks, so that the internal structure of the chuck is simplified, and the processing and manufacturing cost is reduced.

2. The pile body can be clamped by the inclined block through clamping the pile body only with small force, so that the weight of the used first oil cylinder is reduced, and the total weight of the clamping head is reduced.

Detailed Description

The present utility model is substantially identical to the structure of CN201920337492.1, and is improved only in the chuck part.

As shown in fig. 1-2, a pile press according to the present utility model includes: a frame, a pile pressing cylinder 4 and a chuck 6. The frame comprises a base 1, a guide rod 2 arranged on the base and a cross beam 3 arranged on the guide rod. A collet 6 is located below the cross beam 3 for clamping the pile body in operation, the collet 6 being of hollow construction and having an inclined inner wall. The inclined block 5 is arranged in the chuck, the inclined block comprises two inclined blocks which are symmetrically arranged, the inclined block 5 is matched with the inclined plane, the inclined block is driven by the first oil cylinder 7, the first oil cylinder 7 is fixedly connected with the chuck 6 through the connecting plate 8, a piston rod 71 of the first oil cylinder 7 is fixedly connected with the inclined block 5, and the inclined block 5 is pushed by the piston rod 71 of the first oil cylinder 7 to realize up-and-down movement. The pile pressing cylinder 4 includes a cylinder fixedly provided on the cross beam 3, and a piston rod (not shown) which is movable up and down through the cross beam 3, the piston rod pushing the collet 6 up and down along the guide rod 2.

According to the utility model, the inclined block is pushed to clamp the pile body through the first oil cylinder 7, so that the internal structure of the chuck is simplified, and the processing and manufacturing cost is reduced.

Other parts of the present utility model are identical to the structure of CN201920337492.1 and will not be described in detail herein.
