Description

Technical Field

[0001] This utility model belongs to the field of concrete pump truck technology, and in particular relates to quick-install clamps for the boom tube of concrete pump trucks. Background Technology

[0002] Traditionally, concrete pump truck boom pipes are connected using flange bolts, requiring multiple people to work at height for disassembly and assembly, which is time-consuming and poses safety hazards. Bolts are prone to rust and jamming, resulting in low maintenance and replacement efficiency; grout leakage from the sealing surface under high-pressure pumping accelerates pipe wear. Existing clamp structures are complex and cannot meet the rapid locking requirements of high-frequency vibration conditions of the boom. Therefore, we designed a quick-install clamp for concrete pump truck boom pipes. This clamp is installed using a combination of a clamp, pins, and bolts for locking, allowing for detachment of the conveying pipe. Furthermore, the clamp's installation position can be freely changed, eliminating the need for a specific installation location and facilitating quick connection. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-install clamp for the boom pipe of a concrete pump truck. It features installation by using a clamp in conjunction with pins and bolts for locking, which allows the conveying pipe to be disassembled. Moreover, the clamp installation position can be changed at will, without the need for a specific installation position, and it is convenient and quick to connect, thus solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a quick-install clamp for the boom pipe of a concrete pump truck, which includes a U-shaped long plate fixed on one side of the folding boom on the pump truck and multiple clamp components installed on the surface of the pumping pipe. The clamp components include half-clamp one and half-clamp two sleeved on the surface of the pumping pipe. Half-clamp one and half-clamp two are installed together by four bolts. A thick screw is welded to the middle of the outer side of half-clamp two. A long groove for inserting the thick screw is opened on the U-shaped long plate. A positioning plate is sleeved on the surface of the thick screw. Two symmetrical positioning rods are fixedly connected to one side of the positioning plate. Multiple matching insertion holes for inserting the positioning rods are opened in the inner cavity of the long groove.

[0005] Preferably, the distance between the two positioning rods is the same as the distance between the two insertion holes in the inner cavity of the long groove.

[0006] Preferably, the outer diameter of the positioning rod is the same as the inner diameter of the insertion hole, and the diameter of the inner cavity of the insertion hole is greater than the width of the inner cavity of the long groove.

[0007] Preferably, the surface of the coarse screw is threaded with a nut that abuts against one side of the positioning plate.

[0008] Preferably, the surface of the coarse screw is threaded with a nut two that abuts against the outside of the U-shaped long plate.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model involves fitting half-hoops one and two onto the surface of the pumping pipe, then inserting the coarse screw on half-hoops two into the inner cavity of the long groove on the U-shaped plate, then fitting a positioning plate onto the surface of the coarse screw, allowing the positioning rod to be inserted into the inner cavity of the insertion hole for limiting, then tightening the bolts to secure half-hoops one and two onto the surface of the pumping pipe, and finally tightening nuts one and two to connect the pumping pipe to the folding arm. This allows for installation by using clamps in conjunction with pins and bolts for locking, making the conveying pipe detachable and allowing the clamp installation position to be changed at will without requiring a specific installation position, thus facilitating quick and easy connection.

[0019] In the following description, embodiments of the quick-install clamp for the boom tube of a concrete pump truck according to the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-4This invention illustrates a quick-release clamp for a concrete pump truck boom pipe according to an embodiment of the present invention. It includes a U-shaped long plate 2 fixed to one side of the folding boom 1 on the pump truck and multiple clamp assemblies 4 mounted on the surface of the pumping pipe 3. Each clamp assembly 4 includes a first clamp 41 and a second clamp 42 fitted onto the surface of the pumping pipe 3. The first clamp 41 and the second clamp 42 are connected by four bolts 43. A coarse threaded rod 44 is welded to the middle of the outer side of the second clamp 42. A long groove 45 is provided on the U-shaped long plate 2 for inserting the coarse threaded rod 44. A positioning plate 46 is fitted onto the surface of the coarse threaded rod 44. One side of the positioning plate 46 is fixedly connected to two symmetrical positioning rods 47. Multiple positioning rods 47 are provided within the cavity of the long groove 45. 7. The corresponding insertion hole 48 is inserted. The distance between the two positioning rods 47 is the same as the distance between the two insertion holes 48 in the inner cavity of the long groove 45. The outer diameter of the positioning rod 47 is the same as the inner diameter of the insertion hole 48. The diameter of the inner cavity of the insertion hole 48 is greater than the width of the inner cavity of the long groove 45. The surface of the coarse screw 44 is threaded with a nut 49 that abuts against one side of the positioning plate 46. Through the cooperation of the insertion hole 48 and the nut 49, the length of the coarse screw 44 extending on the U-shaped long plate 2 can be adjusted, and the distance between the pumping pipe 3 and the folding arm 1 can be adjusted. It can be installed as needed. The surface of the coarse screw 44 is threaded with a nut 410 that abuts against the outside of the U-shaped long plate 2.

[0021] Working principle: When using this utility model, when installing the pumping pipe 3 and the folding arm 1, the first half-hoop 41 and the second half-hoop 42 are placed on the surface of the pumping pipe 3. At this time, the bolt 43 does not need to be tightened. Adjust the position of the first half-hoop 41 and the second half-hoop 42 on the pumping pipe 3. Then, insert the coarse screw 44 on the second half-hoop 42 into the inner cavity of the long groove 45 on the U-shaped long plate 2. Then, pick up the positioning plate 46 and put it on the surface of the coarse screw 44 from the inside of the U-shaped long plate 2. Then, make the positioning plate 46 spread out so that the two positioning rods 47 are inserted into the inner cavity of the insertion hole 48 at the long groove 45, and position the coarse screw 44 at this time. Then, tighten the nuts 49 and 410 to achieve quick connection. If there is a problem with the pumping pipe 3 later, simply unscrew the nut 49 and pull the pumping pipe 3 outward to remove the coarse screw 44 from the inner cavity of the long groove 45, which is convenient for disassembly, maintenance and replacement.

[0022] In summary: This quick-install clamp for the concrete pump truck boom pipe is achieved by fitting half-clamp 1 41 and half-clamp 2 42 onto the surface of the pumping pipe 3. Then, the coarse threaded rod 44 on half-clamp 2 42 is inserted into the inner cavity of the long groove 45 on the U-shaped long plate 2. Next, a positioning plate 46 is fitted onto the surface of the coarse threaded rod 44, allowing the positioning insert 47 to be inserted into the inner cavity of the insertion hole 48 for positioning. Then, the bolt 43 is tightened, ensuring that half-clamp 1 41 and half-clamp 2 42 are securely fixed to the surface of the pumping pipe 3. Finally, nuts 1 49 and 2 410 are tightened to connect the pumping pipe 3 to the folding boom 1. This method of installation using clamps, pins, and bolts allows for easy detachment of the conveying pipe and flexible clamp installation position, eliminating the need for a specific installation location and facilitating quick connection.
