Concrete pump truck boom tip anti-shake stabilizer

Abstract

This utility model discloses a vibration stabilizer for the end of a concrete pump truck boom, comprising a vibration stabilizing component installed at the end of the pump truck boom and the end of the conveying pipe. The pump truck boom is fixedly installed to the conveying pipe. The vibration stabilizing component includes a first half-hoop plate fitted onto the surface of the conveying pipe. The first half-hoop plate is installed to the conveying pipe, and a second half-hoop plate fitted onto the surface of the conveying pipe is hinged to one side of the first half-hoop plate. This utility model uses a flip-fitting U-shaped connecting seat, screw rod, and washer nut to lock the first and second half-hoop plates onto the surface of the conveying pipe. The arc-shaped rubber pads inside the first and second half-hoop plates adhere to the surface of the conveying pipe and absorb vibration energy. Combined with the counterweight at the bottom, this reduces the vibration amplitude at the end of the pump truck boom. Thus, the rubber pad clamps absorb the pressure-induced vibration of the pipe during concrete conveying, and the downward-sloping counterweight further reduces the vibration amplitude.

Description

Technical Field

[0001] This utility model belongs to the field of concrete pump truck technology, and in particular relates to a vibration stabilizer at the end of the boom of a concrete pump truck. Background Technology

[0002] During operation, the conveying pressure and flow rate of a concrete pump are not always constant. For example, a sudden increase in conveying pressure can generate a large reaction force on the boom end, while a decrease in pressure may lead to uneven concrete discharge. These unstable conditions can cause the boom end to vibrate. In addition, fluctuations in the conveying flow rate can also affect the continuity and stability of concrete placement, thus causing end vibration.

[0003] The pump truck boom end and the end of the conveying pipeline are generally rigidly connected. The force of pipeline vibration will directly act on the pump truck boom, causing it to vibrate. In order to reduce the vibration of the pump truck boom end and ensure more stable and accurate concrete placement, we designed a concrete pump truck boom end anti-vibration stabilizer. It uses rubber pad clamps to absorb the pressure of the pipeline during concrete conveying, and with the help of a downward counterweight, it reduces the vibration amplitude. Utility Model Content

[0004] The purpose of this invention is to provide a vibration stabilizer for the end of a concrete pump truck boom, which has the advantages of using rubber pad clamps to absorb the pressure of the pipeline during concrete transportation, and using a downward-sloping counterweight to reduce the vibration amplitude, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a concrete pump truck boom end anti-shaking stabilizer, which includes an anti-shaking component set at the end of the pump truck boom rod and the end of the conveying pipe. The pump truck boom rod is fixedly installed with the conveying pipe. The anti-shaking component includes a half-hoop plate one sleeved on the surface of the conveying pipe. The half-hoop plate one is installed with the conveying pipe. A second half-hoop plate is hinged to one side of the half-hoop plate one and sleeved on the surface of the conveying pipe. An arc-shaped rubber pad is bonded to the inner cavity of both the first and second half-hoop plates. The arc-shaped rubber pad is in contact with the surface of the conveying pipe. A counterweight is detachably installed in the middle of the bottom of the first half-hoop plate.

[0006] Preferably, two symmetrical U-shaped connecting seats are welded to one side of both the first and second half-hoops. A screw rod is rotatably connected to the inner cavity of one of the U-shaped connecting seats, and the screw rod passes through the inner cavity of the other U-shaped connecting seat and is threaded with a washer nut.

[0007] Preferably, a hanging ring is welded to the bottom of the first half-hoop plate, a hook is attached to the hanging ring, a connecting rope is installed at the bottom of the hanging ring, and the bottom of the connecting rope is fixedly connected to the counterweight.

[0008] Preferably, a connecting seat is welded to one side of the first half-hoop plate, and a shaft is installed in each of the two inner cavities of the connecting seat. A rotating block is rotatably connected to the surface, and one side of the rotating block is fixedly connected to the second half-hoop plate.

[0020] In the following description, embodiments of the concrete pump truck boom end anti-shake stabilizer of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a concrete pump truck boom end anti-shake stabilizer according to an embodiment of the present invention. It includes an anti-shake component 3 disposed at the ends of the pump truck boom end rod 1 and the conveying pipe 2. The pump truck boom end rod 1 is fixedly installed to the conveying pipe 2. The anti-shake component 3 includes a first half-hoop plate 31 sleeved on the surface of the conveying pipe 2. The first half-hoop plate 31 is installed to the conveying pipe 2. A second half-hoop plate 32, also sleeved on the surface of the conveying pipe 2, is hinged to one side of the first half-hoop plate 31. An arc-shaped rubber pad 33 is bonded to the inner cavity of both the first half-hoop plate 31 and the second half-hoop plate 32, and the arc-shaped rubber pad 33 is in contact with the surface of the conveying pipe 2. A counterweight block 37 is detachably installed at the center of the bottom of the first half-hoop plate 31. Two symmetrical U-shaped connecting seats 34 are welded to one side of both the first half-hoop plate 31 and the second half-hoop plate 32. A screw rod 35 is rotatably connected to the inner cavity of one of the U-shaped connecting seats 34, and the screw rod 35 passes through the other U-shaped connecting seat 34. The inner cavity of the receiving seat 34 is threaded with a washer nut 36. The bottom of the half-hoop plate 31 is welded with a hanging ring 38, and a hook 39 is attached to the hanging ring 38. A connecting rope 310 is installed at the bottom of the hanging ring 38. The bottom of the connecting rope 310 is fixedly connected to the counterweight 37. Through the cooperation of the hanging ring 38, the hook 39 and the connecting rope 310, the counterweight 37 can be removed when the pump truck is not in use. Simply remove the hook 39 from the hanging ring 38 and then wrap the connecting rope 310 around the surface of the counterweight 37 for storage. A connecting seat 311 is welded to one side of the half-hoop plate 31. The two inner cavities of the connecting seat 311 are each equipped with a shaft 312. A rotating block 313 is rotatably connected to the surface of the shaft 312. One side of the rotating block 313 is fixedly connected to the second half-hoop plate 32. Two symmetrical support rods are welded to the outer side of the half-hoop plate 31. The support rods are welded to the end rod 1 of the pump truck arm.

[0022] Working principle: When this utility model is used, the first half-hoop plate 31 and the second half-hoop plate 32 are flipped and wrapped around the surface of the conveying pipe 2. Then, the screw rod 35 in the inner cavity of the U-shaped connecting seat 34 is rotated to the inner cavity of the other U-shaped connecting seat 34. Then, the fastening washer nut 36 is tightened to lock the first half-hoop plate 31 and the second half-hoop plate 32 onto the surface of the conveying pipe 2. The arc-shaped rubber pad 33 in the inner cavity of the first half-hoop plate 31 and the second half-hoop plate 32 will absorb vibration energy when it is attached to the surface of the conveying pipe 2. Then, the hook 39 is hung on the surface of the hanging ring 38. The weight of the bottom counterweight 37 will be applied to the anti-vibration component 3, reducing the vibration amplitude of the end of the pump truck arm rod 1, and ensuring that the concrete placement is more stable and accurate.

[0023] In summary, this concrete pump truck boom end anti-vibration stabilizer, through the flipping and engagement of half-hoop one 31 and half-hoop two 32 with U-shaped connecting seat 34, screw rod 35 and washer nut 36, locks half-hoop one 31 and half-hoop two 32 onto the surface of the conveying pipe 2. The arc-shaped rubber pads 33 inside the half-hoop one 31 and half-hoop two 32 adhere to the surface of the conveying pipe 2 and absorb vibration energy. Combined with the counterweight block 37 at the bottom, it reduces the vibration amplitude at the end of the pump truck boom 1. Thus, the rubber pad clamp absorbs the pressure of the pipe being pulled during concrete conveying, and with the downward counterweight, it reduces the vibration amplitude.
