Description

Technical Field

[0001] This application relates to the field of concrete delivery pump pipes, and more particularly to fixed supports for corners of concrete delivery pump pipes. Background Technology

[0002] When pouring concrete for high-rise buildings, a concrete delivery pump pipe must be used to transport the concrete to the concrete placing boom for pouring. A common method to reinforce the delivery pump pipe is to pour concrete piers and enclose the pump pipe inside the piers to secure it. However, because the delivery pump pipe bears the dynamic load and friction generated during the concrete transportation process, especially at the connection between horizontal and vertical pipe sections, it is prone to blockage and bursting. When this happens, the treatment process is often too long, resulting in cold joints in the concrete structure, creating structural defects that fail to meet market demands. Utility Model Content

The connecting ears are inserted into the interior of the mounting groove.

[0006] By adopting the above technical solution, the straight section of the pump pipe passes between the two limiting blocks. The height of the limiting blocks is adjusted so that the limiting slots on them are aligned with the center of the pump pipe. Then, the nuts under the fastening bolts are tightened so that the limiting blocks tightly hold the pump pipe through the rubber protective ring, and the installation is complete.

[0007] Preferably, the connecting ear is movable inside the mounting groove, the connecting ear is provided with a plug hole, the moving groove is provided with a fastening bolt, the fastening bolt is inserted into the plug hole, and the lower part of the fastening bolt is threaded with a fastening nut, the fastening nut abutting against the lower surface of the extension rod.

[0015] Preferably, an arc-shaped seat is installed at the inner corner of the L-shaped seat, and an arc-shaped protective pad is installed on the arc-shaped seat, with the arc-shaped protective pad fitting against the corner of the pump pipe.

[0016] By adopting the above technical solution, the arc-shaped protective pad fits snugly at the corner of the pump pipe, providing bottom support and protection for the corner of the pump pipe.

[0017] Preferably, the upper and lower parts of the arc-shaped seat are provided with limit bolts, the L-shaped seat is fitted with a limit sleeve by the limit bolts, the pump pipe is located inside the limit sleeve, a support seat is installed on the L-shaped seat, and the pump pipe is located on the support seat.

[0020] 1. This application clamps the pump pipe from both sides using two adjustable extension rods and limiting blocks, and together with the arc-shaped seat at the bottom and the limiting sleeve at the top, forms a three-dimensional surrounding fixation for the corner of the pump pipe. This effectively resists the multi-directional impact and vibration generated during concrete pumping, preventing the pump pipe from shifting or loosening. The rubber protective ring inside the limiting block and the arc-shaped protective pad on the arc-shaped seat are both made of elastic material, which can effectively absorb vibration energy, reduce hard impact on the pump pipe, and prevent metal parts from directly rubbing against the outer wall of the pump pipe, thus playing a good buffering and protective role and extending the service life of the pump pipe.

[0021] 2. This application, through the design of multiple sets of mounting holes, allows for adjustment of the distance between two fixed supports to accommodate pump pipes of different diameters. At the same time, the limiting block can be finely adjusted by moving the connecting ear in the mounting groove, ensuring that the limiting block can accurately and tightly fit the pump pipe. The entire support structure is reasonably designed, with the L-shaped seat, support seat, and limiting sleeve forming a stable support system. All connections are made with bolts, making disassembly and assembly convenient and facilitating on-site installation, adjustment, and maintenance. Attached Figure Description

The L-shaped seat 2 has a mounting hole 3, and a fixing plate 4 is installed on the L-shaped seat 2 at the mounting hole 3. The fixing plate 4 and the L-shaped seat 2 are connected by bolts 5. An extension rod 6 is installed on the fixing plate 4. A mounting groove 7 is formed through the side of the extension rod 6, and a moving groove 8 is formed through the upper and lower parts of the extension rod 6. A limit block 9 is provided on the inner side of the extension rod 6, and connecting ears 10 are provided on both sides of the limit block 9. The connecting ears 10 are inserted into the interior of the mounting groove 7 and can move within the mounting groove 7. The connecting ears 10 have insertion holes. The hole 11 and the moving groove 8 are provided with a fastening bolt 12. The fastening bolt 12 is inserted into the insertion hole 11, and the lower part of the fastening bolt 12 is threaded with a fastening nut. The fastening nut abuts against the lower surface of the extension rod 6. The connecting lug 10 is inserted into the mounting groove 7 of the extension rod 6, so that the limiting block 9 can move up and down relative to the extension rod 6. The fastening bolt 12 passes through the insertion hole 11 on the moving groove 8 and the connecting lug 10, and is locked from below by the fastening nut. When the nut is tightened, the limiting block 9 is firmly pressed onto the extension rod 6 to achieve fixation. Loosening the nut makes it convenient to adjust the position of the limiting block 9 when fixing pump pipes 1 of different specifications.

[0030] Please refer to Figures 1 to 4 There are two fixing plates 4 and extension rods 6. The limiting block 9 is located between the two extension rods 6.

An arc-shaped seat 16 is fixed by welding or bolts, and an arc-shaped protective pad 17 is covered on the arc-shaped seat 16. The bent part of the pump pipe 1 rests on the arc-shaped protective pad 17, which provides bottom support and protection. In order to further prevent the pump pipe 1 from jumping, a limiting sleeve 18 is installed on the L-shaped seat 2 by limiting bolts 19. The limiting sleeve 18 covers the bent part of the pump pipe from above. At the same time, a support seat 20 is also installed on the L-shaped seat 2 to provide auxiliary support for the straight part of the pump pipe 1.

[0034] The implementation principle of the fixed support for the corner of the concrete conveying pump pipe in this embodiment is as follows: During installation, firstly, the L-shaped seat 2 is fixed in the predetermined position. According to the specifications of the pump pipe 1, a suitable mounting hole 3 is selected to install the fixing plate 4 and the extension rod 6. The elbow of the pump pipe 1 is placed on the arc-shaped protective pad 17, and the straight section passes between the two limiting blocks 9. The height of the limiting block 9 is adjusted so that the limiting slot 13 on it is aligned with the center of the pump pipe 1. Then, the nut below the fastening bolt 12 is tightened so that the limiting block 9 tightly hugs the pump pipe 1 through the rubber protective ring 15. Finally, the upper limit sleeve 18 and the support seat 20 are installed to complete the entire fixing process. When pumping concrete, the fixed support can constrain the corner of the pump pipe from both sides, bottom and top at the same time, effectively suppressing its vibration and displacement.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
