Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a sliding pile driver. Background Art

[0002] A skidding pile driver is a type of mechanical equipment commonly used in construction sites and bridge construction. It has the characteristics of flexible mobility, easy operation, and high construction efficiency. The equipment adopts a sliding design, which allows it to slide freely during the construction process and facilitate the adjustment of the working position. At the same time, it is also equipped with a powerful piling function, which can complete the piling operation quickly and accurately.

[0003] The sliding pile driver is divided into a unidirectional pile driver and a bidirectional side-shift pile driver. The existing bidirectional side-shift pile driver has some shortcomings. For example, the patent publication number CN213741055U discloses a bidirectional side-shift sliding pile driver, which includes a supporting device, a connecting device, a telescopic device, a fixing device and a sliding device. One end of the telescopic device is connected to the connecting device, and the two side surfaces of the telescopic device are connected to the inner surfaces of the two sides of the supporting device. The fixing device is arranged on the upper surface of the supporting device, and the sliding device is arranged inside the telescopic device. When in use, the positioning and adjustment of the telescopic tube are achieved by the cooperation of the latch and the pin hole. However, the latch inserted in the pin hole is not firmly fixed. When the pile driver is working, the latch and the pin hole will be loosened due to the vibration of the equipment, affecting the stability of the positioning of the telescopic tube. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a sliding pile driver which can make the latch more firmly fixed, avoid the latch from loosening due to vibration during equipment operation, and improve the positioning stability of the telescopic tube.

[0005] Technical Solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sliding pile driver, including a supporting device and a fixing mechanism, wherein a telescopic tube is movably provided on the supporting device, and a pin hole is provided on the telescopic tube, and the fixing mechanism includes a fixing frame, which is fixedly mounted on the top of the supporting device, and a guide hole is provided in the middle of the top of the fixing frame, and a latch is slidably provided in the guide hole, and a pressure plate is fixedly connected to the top of the latch, and the latch passes through the top of the supporting device and is inserted into the pin hole of the telescopic tube, and a front support plate and a rear support plate are fixedly connected to the top of the fixing frame symmetrically in front and back. The front support plate is provided with a threaded hole, the rear support plate is provided with a sliding hole, the front support plate is provided with an adjusting screw rod through the matching screw of the threaded hole, the rear support plate is provided with a guide rod through the matching sliding hole, the front end of the adjusting screw rod is fixedly connected with a fixing cap, the fixing cap is fixedly provided with a twist handle, the rear end of the adjusting screw rod and the front end of the guide rod are rotatably connected with a limiting block, the two sets of limiting blocks are hinged with transmission strips, the bottom ends of the two sets of transmission strips are hinged with the top end of the pressure plate, the threaded sleeve on the adjusting screw rod is provided with an anti-loosening lock nut, and the rear end of the anti-loosening lock nut is tightly attached to the front end of the front support plate.

[0007] Preferably, anti-slip handle covers are fixedly provided on both the left and right sides of the twist handle.

[0008] Preferably, a handle is fixedly connected to the anti-loosening lock nut.

[0009] Preferably, a sliding sleeve is fixedly provided in the sliding hole on the rear support plate.

[0010] Preferably, rib plates are fixedly connected between the left and right sides of the handle and the outer wall of the anti-loosening lock nut.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when fixing the position of the telescopic tube, the latch pin is aligned with the pin hole on the telescopic tube, and then the adjusting screw rod is adjusted by twisting the handle to make the adjusting screw rod push the limit block to move inward, and the limit block pushes the pressure plate downward through the transmission strip plate, so that the pressure plate pushes the latch pin to slide downward. When the bottom end of the pressure plate is tightly attached to the top end of the fixing frame, the bottom end of the latch pin has been inserted into the pin hole. At this time, the anti-loosening lock nut is tightened by screwing the anti-loosening lock nut, so that the rear end of the anti-loosening lock nut is tightly attached to the front end of the front support plate, so that the anti-loosening lock nut locks the adjusting screw rod to prevent the adjusting screw rod from rotating and loosening, so that the pressure plate is always pressed on the top end of the fixing frame, thereby effectively preventing the latch pin from detaching from the pin hole, making the latch pin more securely fixed, avoiding the latch pin from loosening due to vibration during equipment operation, and improving the positioning stability of the telescopic tube.
