Description

Technical field:

[0001] The utility model relates to the technical field of pile driving positioning, in particular to an auxiliary positioning mechanism for a pile driver. Background technology:

[0002] A pile driver consists of a pile hammer, pile frame, and ancillary equipment. The hammer is attached between two parallel vertical guide rods at the front of the pile frame. The pile is lifted with a lifting hook and placed at a fixed location. An auxiliary positioning mechanism then replaces manual support to position and support the pile. For irregular-shaped piles, manual support is also required.

[0003] The existing auxiliary positioning mechanism is mainly composed of multiple multi-section telescopic rods and splints. The bottom end of the multi-section telescopic rod is fixedly connected to the top surface of the pile driver, and the top end of the multi-section telescopic rod is threadedly connected to the splint. However, the splint cannot be used to position the special-shaped piles when piling. The splint interferes with the placement of the piles and requires the staff to remove the splint and then place the piles. When the splint is needed for positioning, the splint needs to be fixed to the top end of the multi-section telescopic rod by bolts. The large number of splints makes it inconvenient to disassemble and assemble. Utility model content:

[0004] To this end, the purpose of the present utility model is to provide an auxiliary positioning mechanism for a pile driver to overcome the problems of the prior art because the existing auxiliary positioning mechanism is mainly composed of multiple multi-section telescopic rods and splints, the bottom ends of the multi-section telescopic rods are fixedly connected to the top surface of the pile driver, and the top ends of the multi-section telescopic rods are threadedly connected to the splints. However, when piling special-shaped piles, the splints cannot be used to position them. The splints interfere with the placement of the piles, and the staff need to remove the splints before placing the piles. When the splints need to be used for positioning, the splints need to be fixed to the top ends of the multi-section telescopic rods by bolts, and the splints are too many and inconvenient to disassemble and assemble.

[0005] The utility model is implemented by the following technical solutions:

[0006] The cam is fixedly mounted on the support frame of the U-shaped support plate, and the cam is fixedly mounted on the support frame of the U-shaped support plate.

[0007] Preferably, the radius of the positioning groove gradually increases from bottom to top.

[0008] Preferably, the radius of the positioning groove gradually increases in a direction away from the pile hammer of the pile driver.

[0009] Preferably, the rotating assembly includes a bearing fixedly arranged on the side wall of the slider, a square rod is fixedly connected between the inner rings of the two bearings, a through groove is slidingly sleeved on the square rod, the through groove is opened on the side wall of the splint, and two return springs are sleeved on the square rod, and the return springs are arranged between the slider and the splint and fit with their side walls.

[0010] Preferably, a rubber bump is fixedly connected to the bottom surface of the clamping plate, the cross section of the rubber bump is semicircular, the rubber bump is slidably arranged in a limiting groove, and the limiting groove is provided on the top surface of the horizontal plate of the U-shaped support plate.

[0012] The advantages of the present invention are as follows: two clamps are slidably connected between the two sliding blocks at the side ends of the U-shaped supporting plate through a rotating assembly. When the clamps are needed to position the piles, the clamps are rotated to be set horizontally to position the piles. When the clamps are not used to position the special-shaped piles, the clamps can be rotated to hide them between the vertical plates of the U-shaped supporting plate. The clamps do not occupy the operating space on the top surface of the pile driver, reducing the influence of the clamps on the pile driving. Description of the drawings:

[0025] like Figures 1-6 As shown, the utility model provides the following technical solutions: an auxiliary positioning mechanism for a pile driver, comprising a U-shaped support plate 1 fixed at the side end of the pile driver, a slide groove 2 being opened on the side wall of the vertical plate of the U-shaped support plate 1, a slider 3 slidingly fitted in the slide groove 2, a first compression spring 4 fixedly connected between the bottom surface of the slider 3 and the support plate 1, the first compression spring 4 being arranged in the slide groove 2, the two sliders 3 being arranged facing each other, a rotating assembly being fixedly connected between the two sliders 3, two plywood 7 being slidingly sleeved on the rotating assembly, the two plywood 7 being arranged fittingly with each other, a plurality of positioning grooves 9 being opened on the side wall of the plywood 7 from bottom to top, the positioning grooves 9 on the two plywood 7 being arranged facing each other and the circles where the arc surfaces of the positioning grooves 9 facing each other coincide, a positioning rod 11 fitting in the side wall of the plywood 7 being fixedly connected between the two sliders 3.

[0026] Please combine Figure 1 When the pile is in the ground, the pile is moved downwards, and the clamping plate 7 is rotated to a vertical position and hidden between the two vertical plates of the U-shaped support plate 1, and then the pile driving operation of the special-shaped pile is carried out. The clamping plate 7 does not occupy the operating space on the top surface of the pile driver, reducing the influence of the clamping plate 7 on the pile driving of the special-shaped pile, and there is no need to disassemble and assemble the clamping plate 7.

[0027] After the piling is completed, the bolts between the two clamping plates 7 are unscrewed, and then the clamping plates 7 are pulled, and the pile pushes the two clamping plates 7 to move in opposite directions, thereby realizing the separation of the clamping plates 7 and the pile.

[0028] The radius of the positioning groove 9 increases gradually from bottom to top.

[0029] Please combine Figure 1 As shown, during use, the splint 7 is rotated to be horizontal, and then the horizontal splint 7 is pushed to move, and the splint 7 drives the positioning groove 9 to move, and the corresponding positioning groove 9 is moved to the piling positioning point. The radius of the positioning groove 9 gradually increases from bottom to top, which is convenient for positioning piles of different models.

[0030] The radius of the positioning groove 9 gradually increases in a direction away from the pile hammer of the pile driver.

[0031] Please combine Figure 5 、 Figure 6 As shown, during use, the splint 7 is rotated to be horizontal, and the radius of the positioning groove 9 at the top end of the splint 7 is larger than the radius of the positioning groove 9 at the bottom end, which facilitates the insertion of the pile.

[0032] The rotating assembly includes a bearing 5 fixedly arranged on the side wall of the slider 3, a square rod 6 fixedly connected between the inner rings of the two bearings 5, a through groove 8 is slidingly sleeved on the square rod 6, and the through groove 8 is opened on the side wall of the splint 7. Two return springs 10 are sleeved on the square rod 6, and the return springs 10 are arranged between the slider 3 and the splint 7 and are in contact with their side walls.

[0033] Please combine Figure 1As shown, during use, the splint 7 is rotated to be horizontal, the splint 7 drives the square rod 6 to rotate, and the square rod 6 drives the inner ring of the bearing 5 to rotate. When the splint 7 is horizontal, the splint 7 is pushed to move, and the splint 7 drives the through slot 8 to slide on the square rod 6, and the splint 7 drives the positioning slot 9 to slide, which is convenient for positioning different types of piles.

[0034] After the pile is positioned, the clamping plate 7 is pulled apart from the pile, and the pile pushes the clamping plate 7 to move in an opposite direction, squeezing the reset spring 10 to deform.

[0035] A rubber bump 14 is fixedly connected to the bottom surface of the clamping plate 7. The cross section of the rubber bump 14 is semicircular. The rubber bump 14 is slidably arranged in a limiting groove 15. The limiting groove 15 is opened on the top surface of the horizontal plate of the U-shaped support plate 1.

[0036] Please combine Figure 1 As shown, during use, when the rotating splint 7 is in a vertical state, the splint 7 drives the rubber protrusion 14 to slide into the limiting groove 15. The limiting groove 15 limits the rubber protrusion 14 to prevent the rubber protrusion 14 from rotating unintentionally, thereby preventing the splint 7 from rotating and improving the stability of the splint 7.

[0037] A plurality of rubber blocks 12 are fixedly connected to the side wall of the clamping plate 7 from bottom to top. The cross section of the rubber block 12 is semicircular. The top surface of the positioning rod 11 is a concave arc surface and matches the rubber block 12.

[0038] Please combine Figure 5 As shown, during use, when the splint 7 is pushed to move laterally, the splint 7 drives the positioning groove 9 to move, and the splint 7 drives the rubber block 12 to move. When the rubber block 12 moves and slides into the concave arc surface of the top surface of the positioning rod 11, the corresponding positioning groove 9 is exactly in the center of the pile driver. The rubber block 12 plays a positioning role in the movement of the positioning groove 9, thereby reducing the occurrence of deviation when the positioning groove 9 moves.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
