Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and particularly to a leakage-preventing pumping device for thin-walled high-pier bridge construction. Background Art

[0002] When constructing a thin-walled high pier construction site, it may cause the pump truck to be unable to approach the construction location. Therefore, it is necessary to cooperate and connect a truck-mounted pump truck and a long-distance pump pipe to achieve pumping and pouring. In the prior art, generally, connecting pump pipes are used to connect multiple sections of pump pipes so that concrete can be fed to a higher position. However, such a method also has disadvantages. For example:

[0003] First, multiple pump pipes need to be carried with each construction. Due to the material characteristics of the pump pipes, it is also troublesome to carry them.

[0004] Second, the connection of the pump pipes needs to be carried out before each construction. The pump pipe body is relatively heavy, which is troublesome both when moving and installing.

[0005] And during construction, when the concrete slurry is discharged, it needs to be discharged according to the construction environment. Generally, the end of the concrete discharge is a vertically-shaped hose. Generally, construction workers are required to pull the hose to move the hose to the position where the concrete slurry is needed for discharging, so as to achieve the uniformity of the concrete discharge and make the concrete slurry evenly spread on the construction platform.

[0006] In the prior art, since the concrete slurry generally does not stop during the discharging process, and the manual traction method requires people to be relatively close to the hose, this will cause the concrete slurry to easily splash onto the construction workers when it lands and splashes. Therefore, the manual traction method has a greater risk. And because the concrete slurry generally does not stop during the discharging process, the weight of the hose is relatively heavy. Therefore, multiple people may need to operate synchronously during manual traction, which will also waste a large amount of labor costs. Summary of the Invention

[0019] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0020] First, in the present invention, the concrete slurry can be pushed into the fixed connecting pipe through the pumping device. The fixed connecting pipe is used to transition the concrete slurry. Through the driving component, the extension pipe sleeved on the fixed connecting pipe can be horizontally moved along the fixed connecting pipe. In this way, the extension pipe can drive the discharge pipe to move synchronously, thereby extending the discharge distance of the concrete slurry. In the present invention, a scraping component is also provided on the first connecting plate. After the extension pipe transitions the concrete slurry and retracts to the fixed connecting pipe, the scraping component can scrape the inner wall of the extension pipe to prevent residual concrete slurry from sticking to the inner wall of the extension pipe. In this way, the extension pipe will not get stuck with the fixed connecting pipe due to the concrete slurry when retracting; The present application adopts such a pipeline extension method to solve the problem that the pump pipe is troublesome to carry in the prior art, and at the same time solves the problem that the pump pipe needs to be connected before each construction in the prior art. The pump pipe body is heavy, and it is troublesome both when moving and installing.

[0021] Second, the present invention also provides an adjusting mechanism on the discharge pipe. The adjustment can move the discharge end of the discharge pipe, so that the concrete slurry can choose the construction position for discharging when discharging in the discharge pipe, solving the problem that the position of the concrete slurry needs to be manually pulled in the prior art. In the prior art, the manual traction method requires people to be relatively close to the hose, which will cause the concrete slurry to easily splash onto the construction workers when landing and splashing. Therefore, the manual traction method has a relatively high risk. And because the concrete slurry generally does not stop during the discharging process, the weight of the hose will be relatively heavy. Therefore, multiple people may need to operate synchronously during manual traction, which will also waste a large amount of labor costs.

[0022] Third, in the present invention, when the pump pipe needs to be extended, the rotation of the threaded rod can be driven by the first motor. When the threaded rod rotates, it will cooperate with the limiting rod to drive the moving connecting plate and the extension pipe to move along the fixed connecting pipe. And the inner wall of the extension pipe is in a fitting state with the scraping plate and the first connecting plate. When the extension pipe moves, it will drive the discharge pipe to move synchronously, thereby achieving the effect of extending the pump pipe. After the concrete slurry is discharged, the first motor runs to drive the threaded rod to rotate in the reverse direction to reset the extension pipe and the moving connecting plate. When the extension pipe is reset, the scraping plate will scrape the residual concrete slurry on the inner wall of the extension pipe. In this way, in addition to preventing the extension pipe from getting stuck with the fixed connecting pipe during movement, it is also convenient for the next use of the extension pipe, which can increase the service life of the extension pipe.

First connection plates 21 are symmetrically provided at both ends of the fixed connection pipe 2. One end of the fixed connection pipe 2 is connected to the discharge end of the pumping device 1 through the first connection plate 21. A scraping assembly 24 is provided on the first connection plate 21 at the other end of the fixed connection pipe 2. The driving assembly 3 is arranged at one end of the fixed connection pipe 2 close to the pumping device 1. The extension pipe 4 is slidably sleeved on the fixed connection pipe 2, and the inner wall of the extension pipe 4 is attached to the first connection plate 21. One end of the extension pipe 4 is connected to the driving assembly 3, and the other end of the extension pipe 4 is connected to the discharge pipe 5. The discharge pipe 5 is arc-shaped, and the adjustment mechanism 6 is arranged on the discharge pipe 5.

[0037] In the present invention, the pumping device 1 can be used to push the concrete slurry into the fixed connection pipe 2. The fixed connection pipe 2 is used for transitioning the concrete slurry. The driving assembly 3 can make the extension pipe 4 slidably sleeved on the fixed connection pipe 2 move horizontally along the fixed connection pipe 2. In this way, the discharge pipe 5 can be driven to move synchronously through the extension pipe 4, so as to extend the discharge distance of the concrete slurry. A scraping assembly 24 is also provided on the first connection plate 21 in the present invention. After the extension pipe 4 transitions the concrete slurry and retracts onto the fixed connection pipe 2, the scraping assembly 24 can scrape the inner wall of the extension pipe 4 to prevent residual concrete slurry from sticking to the inner wall of the extension pipe 4. In this way, the extension pipe 4 will not get stuck with the fixed connection pipe 2 due to the concrete slurry when retracting; this application adopts such a pipeline extension method to solve the problem that the pump pipe is troublesome to carry in the prior art, and also solves the problem that the pump pipe needs to be connected before each construction in the prior art. The pump pipe body is heavy, and it is troublesome both when moving and installing.

[0038] The present invention further provides an adjusting mechanism 6 on the discharge pipe 5, which can move the discharge end of the discharge pipe 5, so that the concrete slurry can select the construction position for discharging when discharging in the discharge pipe 5, solving the problem in the prior art that the position of the concrete slurry needs to be manually pulled, and the prior art requires people to be relatively close to the hose, which may cause the concrete slurry to splash onto the construction workers when it lands, so the manual traction method has a relatively high risk. In addition, since the concrete slurry generally does not stop during the discharging process, the weight of the hose is relatively heavy, so multiple people may need to operate synchronously during manual traction, which also wastes a large amount of labor costs.

[0039] Preferably, a fixing plate 22 and a moving connecting plate 23 are further provided on the fixed connecting pipe 2. The fixing plate 22 and the moving connecting plate 23 are spaced on the fixed connecting pipe 2.

[0047] Preferably, the adjusting and linkage assembly 62 includes a linkage fixed plate 621, a linkage fixed rod 622, a rotating connecting rod 623 and a linkage fixed frame 624. There are two linkage fixed plates 621. There are four linkage fixed rods 622. The four linkage fixed rods 622 are symmetrically arranged in pairs between the two linkage fixed plates 621. There are multiple rotating connecting rods 623. Each rotating connecting rod 623 is arranged on a linkage fixed rod 622 on one side of the two linkage fixed plates 621, and the multiple rotating connecting rods 623 are all located in the arc-shaped groove 617.

One end of the moving connecting frame 635 is connected to the eccentric shaft of the adjusting rotating plate 634. The other end of the moving connecting frame 635 is sleeved on the discharge hose 52.

[0049] In the present invention, when the position of the discharge hose 52 needs to be adjusted, first, the driving of the second motor 613 can drive the first driving rod 614 to drive the driving gear 615 to drive the transmission gear 616 to rotate. When the transmission gear 616 rotates, it will drive two linkage fixing plates 621 to rotate synchronously through the linkage fixing frame 624. When the two linkage fixing plates 621 move, they will rotate along the arc-shaped groove 617 in the arc-shaped groove 617 through the linkage fixing rod 622 and the rotating connecting rod 623. In this way, the two linkage fixing plates 621 will drive the fixed connecting plate 631 and the adjusting rotating plate 634 to rotate along the outside of the driving fixing frame 611.

Then, through the operation of the third motor 632, the adjusting rotating plate 634 can be driven to rotate through the second driving rod 633.

In this way, the discharge hose 52 can be adjusted by driving the moving connecting frame 635.
