Description

Technical Field

[0001] The utility model relates to an auxiliary positioning device for pipe pile stacking. Background Art

[0002] Pipe piles are a kind of engineering piles made of concrete, which are widely used in the construction field. As the foundation material of buildings, they are driven into the ground by pile drivers under specific geological environments, which can improve the stability of buildings and compact the soft soil layer, thereby improving the bearing capacity of the foundation soil. After the pipe piles are made, they will be stored together and wait for delivery. The existing storage method is generally to lay the bottom layer of pipe piles flat on a flat open space by a lifting device, and then place limiters at the positions of the pipe piles on both sides to prevent the pipe piles from rolling, and then stack the pipe piles layer by layer. However, since the weight of the pipe piles themselves is large and the pipe piles are cylindrical, the supporting strength of the limiters is weak. There is a possibility that the upper layer of pipe piles will slide due to vibration or collision when lifting other pipe piles, and a chain reaction will be caused when sliding, which will pose a greater threat to the personal safety of on-site workers, and the sliding and damage of the pipe piles will cause certain economic losses. Utility Model Content

[0003] In view of the shortcomings existing in the above problems, the utility model provides an auxiliary positioning device for pipe pile stacking.

[0004] To achieve the above-mentioned purpose, the utility model provides an auxiliary positioning device for pipe pile stacking, comprising bases placed in sequence along the horizontal direction, and adjacent bases can be detachably connected;

[0005] A positioning groove is processed on the upper part of the base for placing pipe piles, an integrated limiting block is provided on the left side wall of the base, and a corresponding limiting groove is provided on the right side wall of the base. Between two adjacent bases, the limiting blocks cooperate to extend into the corresponding limiting grooves and are positioned by positioning pins.

[0006] As a further improvement of the present invention, two opposite side walls of the positioning groove are processed to form inclined surfaces, and the distance between the inclined surfaces gradually increases from bottom to top.

[0007] As a further improvement of the present invention, a through hole is processed in the middle part of the limit block along the front-to-back direction, and the front and rear inner walls of the limit groove correspond to the processed through hole I that penetrates through the end face of the base. After the limit block extends into the limit groove, the shaft of the positioning pin passes through the through hole I in turn, and the through hole forms a positioning.

[0008] The beneficial effects of the utility model are:

[0009] The device utilizes a plurality of bases connected in sequence to provide limited support for the bottom layer of pipe piles. A detachable connection structure is adopted between adjacent bases and they are limited by positioning pins, so they are not easy to come off. The structure is stable and of high strength, and effective support is provided for the stacked pipe piles, so they are not easy to shake and roll off. The number of bases is determined according to the number of pipe piles, and the device is highly practical. The positioning grooves on the upper part of the bases are machined with inclined surfaces on both sides to form a conical opening, which is suitable for stacking pipe piles of different diameters and has good versatility.

[0016] like Figure 1 As shown, an auxiliary positioning device for pipe pile stacking according to an embodiment of the utility model comprises bases 1 placed in sequence along a horizontal direction, and adjacent bases 1 are detachably connected;

[0017] A positioning groove 11 is processed on the upper part of the base 1 for placing the pipe pile 3. The two opposite side walls of the positioning groove 11 are processed to form an inclined surface 12. The distance between the inclined surfaces 12 gradually increases from bottom to top. An integrated limiting block 13 is provided on the left side wall of the base 1. The limiting blocks 13 are arranged in pairs and close to the end of the base 1. A limiting groove 14 is correspondingly provided on the right side wall of the base 1. Between two adjacent bases 1, the limiting blocks 13 cooperate to extend into the corresponding limiting grooves 14 and are positioned by the positioning pin 2. A through hole 131 is processed in the middle part of the limiting block 13 along the front and rear directions. The front and rear inner walls of the limiting groove 14 correspond to the processed through hole I141 that penetrates to the end face of the base 1. After the limiting block 13 extends into the limiting groove 14, the shaft of the positioning pin 2 passes through the through hole I141 and the through hole 131 in sequence to form a positioning.

[0018] The device utilizes a plurality of bases connected in sequence to provide limited support for the bottom layer of pipe piles. A detachable connection structure is adopted between adjacent bases and they are limited by positioning pins, so they are not easy to come off. The structure is stable and of high strength, and effective support is provided for the stacked pipe piles, so they are not easy to shake and roll off. The number of bases is determined according to the number of pipe piles, and the device is highly practical. The positioning grooves on the upper part of the bases are machined with inclined surfaces on both sides to form a conical opening, which is suitable for stacking pipe piles of different diameters and has good versatility.

[0019] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0020] When stacking materials, first determine the number of bases according to the number of pipe piles in the bottom layer, and connect multiple bases in sequence to form an overall structure. Between adjacent bases, the limit blocks are extended into the corresponding limit grooves, and then the positioning pins are inserted to connect and position. Then the pipe piles are hoisted into the positioning grooves of the bases in sequence by the lifting equipment, and then the pipe piles are stacked layer by layer. According to the length of the pipe piles, multiple groups of bases can be set for support; when the base needs to be removed, only the positioning pins need to be pulled out, and the two adjacent bases can be pulled apart. Assembly and disassembly are extremely convenient and easy to operate.

[0021] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
