Description

Technical Field

[0002] Highway hydraulic pile drivers are commonly used in highway projects, also known as guardrail pile drivers / highway guardrail pile drivers. Common pile drivers in construction projects include hydraulic walking diesel hammer pile drivers and high-frequency hydraulic vibration pile drivers. The existing hydraulic pile driver's piling mechanism, due to its single structure, cannot limit and fix the piling parts during use, resulting in the hydraulic machine's parts easily offset during piling.

[0003] Patent No.: CN213390124U, mentions a piling mechanism of a hydraulic pile driver, which can stably fix the vertical pipe by setting a support rod, limit the vertical rod by setting a clamping rod and a clamping hole, and adjust the position of the limit plate by setting a vertical plate and a threaded rod, and limit the parts to be piled to prevent displacement by setting a limit plate, and facilitate the movement of the clamping rod by setting a pull rod, and facilitate the rotation of the threaded rod by setting a turntable, and guide the limit plate by setting a guide rod and a limit block. However, the device uses a limit plate to limit and fix the piling parts. Once the hydraulic press performs piling operations, the piling parts will move down instantly. During this process, friction will occur at the connection between the limit plate and the piling parts, causing wear. After long-term use, a new limit plate needs to be replaced, which is inconvenient. Now a piling mechanism of a hydraulic pile driver is urgently needed to solve the above-mentioned problems.

A metal mounting plate 3 is fixed to the upper right side of the high-strength support plate 1 by bolts, a hydraulic press limiting cylinder 4 is installed on the right end of the metal mounting plate 3, a hydraulic press 5 is longitudinally installed in the hydraulic press limiting cylinder 4, and a metal limiting frame 6 is horizontally fixed to the lower right side of the high-strength support plate 1. Mounting seats 7 are fixed to the four side surfaces of the inner side of the metal limiting frame 6, square cylinders 8 are fixed to both ends of the inner sides of the four mounting seats 7, multiple return springs 12 are installed in the multiple square cylinders 8, rectangular connecting plates 9 are slidably arranged in the multiple square cylinders 8, and mounting blocks 10 are symmetrically installed on the other ends of the multiple rectangular connecting plates 9. Four rollers 11 are arranged. This design solves the problem that the limiting structure is prone to greater wear and tear and has a shorter service life when the original device is used.

[0019] As the first embodiment of the utility model: side supports 2 are installed at the front and rear positions of the lower left end of the high-strength support plate 1, and reinforcing plates 13 are welded at the connection between the two side supports 2 and the lower left end of the high-strength support plate 1. The added side supports 2 and reinforcing plates 13 can enhance the stability of the longitudinal setting of the high-strength support plate 1. Strip grooves 14 are provided on the surface of the high-strength support plate 1. The overall weight of the device can be reduced by the provided strip grooves 14.

The four rollers 11 are movably installed between the plurality of mounting blocks 10 , respectively. The four added rollers 11 can limit and fix the piling component while not affecting the longitudinal piling of the piling component.

[0020] As a second embodiment of the utility model: in actual use, the device is moved to the piling location, and then the multiple rollers 11 are pressed in the opposite direction, so that the multiple rollers 11 can squeeze the multiple rectangular connecting plates 9 through the multiple mounting blocks 10, so that the multiple rectangular connecting plates 9 can move in the multiple square tubes 8 and compress the multiple return springs 12, and then the piling component is placed in the metal limit frame 6, and then the multiple rollers 11 are released, the multiple return springs 12 release the rebound force, and push the multiple rectangular connecting plates 9 towards each other, so that the multiple rectangular connecting plates 9 The four rollers 11 are driven to move toward each other by the multiple mounting blocks 10 until the four rollers 11 are in contact with the side surfaces of the piling component. Then, the remaining resilience of the multiple reset springs 12 is applied to the piling component, so that the piling component is limited and fixed in the metal limit frame 6. The hydraulic press 5 is started, and the hydraulic press 5 drives the piling head 15 to perform the piling operation. During this process, the piling component is struck downward by the piling head 15, and the four rollers 11 roll in situ, thereby reducing the occurrence of wear and tear and enhancing the service life of the limit structure of the device.
