Technical Field

[0001] The present application relates to the technical field of bridge construction equipment, and in particular to a concrete pouring and distributing device for bridge construction. Background Art

[0002] As an important part of the transportation network, the construction quality and safety performance of bridge engineering are directly related to the stable operation of the entire transportation system and the safety of people's lives and property. During the bridge construction process, in order to better adapt to the shape and size of the bridge and ensure the close integration of the bridge deck system with the main structure, it is necessary to use the cast-in-place method to construct the bridge deck system.

[0003] However, in order to solve the problem of structural stress concentration caused by asymmetric pouring, it is necessary to focus on the symmetrical and balanced pouring of the bridge deck system in the transverse and longitudinal directions. In the prior art, multiple vehicle-mounted concrete pumps are often used to pump concrete at the same time. The front, middle and rear ends of the bridge deck are poured simultaneously through the distribution hose of the vehicle-mounted concrete pump. The pumping cost is relatively high, and the distribution hose needs to be manually pulled when unloading the material to distribute the material to the surrounding area. The movement of the distribution hose is relatively difficult and the labor intensity of the workers is high. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a concrete pouring and distributing device for bridge construction, which can reduce the demand for vehicle-mounted concrete pumps during the pouring of the bridge deck system, reduce pumping costs, and reduce the labor intensity of workers.

[0005] An embodiment of the present application provides a concrete pouring and distributing device for bridge construction, comprising a support frame for being erected on a bridge deck casting formwork, the support frame being slidably connected with an inclined material discharge trough, the support frame being provided with a driving assembly for driving the inclined material discharge trough to move in the transverse direction of the bridge on the support frame, a plurality of discharge ports being evenly arranged at the bottom of the inclined material discharge trough, the discharge ports being connected with a material distribution hose, a moving trolley being provided at the lower end of the material distribution hose, a guide frame being fixedly provided at the bottom of the inclined material discharge trough, the moving trolley being slidably connected with the guide frame, and the moving direction of the moving trolley being consistent with the longitudinal direction of the bridge.

[0006] Furthermore, both ends of the inclined material discharge chute are rotatably connected with rollers, the support frame is provided with a first guide groove adapted to the roller, and the roller is rollingly connected to the first guide groove.

[0007] Furthermore, the driving assembly includes a driving motor, a screw and a connecting block, the screw is rotatably arranged on the supporting frame, the driving motor is fixed on the supporting frame, one end of the screw is connected to the output end of the driving motor, the connecting block is fixed at the bottom of the inclined feeding chute, and the screw passes through the connecting block and is threadedly connected to the connecting block.

[0008] Furthermore, the guide frame is provided with a second guide groove adapted to the wheel of the moving trolley, and the wheel of the moving trolley is rollingly connected to the second guide groove.

[0009] Furthermore, a valve is provided at the discharge port.

[0010] Furthermore, a feed port is provided at the upper end of the inclined feed chute.

[0011] Beneficial effects of the utility model:

[0012] When the utility model is in use, the vehicle-mounted concrete pump pumps concrete to the inclined material discharge trough, the concrete moves downward along the inclined material discharge trough, and then falls to different positions of the bridge deck through multiple discharge ports and material distribution hoses. There is no need for multiple vehicle-mounted concrete pumps to work simultaneously, which effectively reduces the pumping cost. Specifically, the driving component drives the inclined material discharge trough to move in the horizontal direction of the bridge on the supporting frame, and the workers pull the lower end of the material distribution hose in the longitudinal direction of the bridge by using a mobile trolley, which is more labor-saving and reduces the labor intensity of the workers.

[0025] like Figure 1and Figure 2 As shown, the present application provides a concrete pouring and distributing device for bridge construction, including a support frame 1 for being erected on a bridge deck system casting formwork, an inclined material discharge chute 2 being slidably connected to the support frame 1, a driving assembly 3 for driving the inclined material discharge chute 2 to move in a transverse direction of the bridge on the support frame 1 is provided on the support frame 1, a plurality of material discharge ports 21 are evenly arranged at the bottom of the inclined material discharge chute 2, and a material distributing hose 4 is connected to the material distributing hose 4. Specifically, in the present embodiment, the material distributing ports 21 are set to 3, and the number of the material distributing hoses 4 is set corresponding to the number of the material distributing ports 21, and the 3 material distributing hoses 4 are respectively located at the front, middle and rear ends of the bridge deck, and a mobile trolley is provided at the lower end of the material distributing hose 4. 5. A guide frame 6 is fixedly provided at the bottom of the inclined material discharge chute 2. The mobile trolley 5 is slidably connected to the guide frame 6. The moving direction of the mobile trolley 5 is consistent with the longitudinal direction of the bridge. When in use, the vehicle-mounted concrete pump pumps concrete to the inclined material discharge chute 2. The concrete moves downward along the inclined material discharge chute 2, and then falls to different positions of the bridge deck through multiple discharge ports 21 and the material distribution hose 4. There is no need for multiple vehicle-mounted concrete pumps to work at the same time, which effectively reduces the pumping cost. Among them, the driving component 3 drives the inclined material discharge chute 2 to move in the transverse direction of the bridge on the support frame 1, and the worker pulls the lower end of the material distribution hose 4 to move in the longitudinal direction of the bridge through the mobile trolley 5, which is more labor-saving and reduces the labor intensity of the workers.

The roller 7 is rollingly connected to the first guide groove 11. When the inclined material chute 2 moves, the roller 7 moves along the first guide groove 11, so that the movement of the inclined material chute 2 is more stable.

The screw 32 passes through the connecting block 33 and is threadedly connected to the connecting block 33. The driving motor 31 drives the screw 32 to rotate and then drives the connecting block 33 to move. When the connecting block 33 moves, it drives the inclined material chute 2 to move, so that the inclined material chute 2 moves along the first guide grooves 11 at corresponding positions through the rollers 7 at both ends.

[0028] like Figure 1As shown, the guide frame 6 is provided with a second guide groove 61 adapted to the wheel of the mobile trolley 5, and the wheel of the mobile trolley 5 is rollingly connected to the second guide groove 61. The worker pulls the mobile trolley 5 to make the wheel of the mobile trolley 5 move along the second guide groove 61, so that the movement is more stable. Specifically, the discharge port of the cloth hose 4 is located below the mobile trolley 5, and the concrete can directly fall onto the casting formwork of the bridge deck system after flowing out of the discharge port of the cloth hose 4.

[0029] like Figure 2 As shown, a valve 8 is provided at the discharge port 21, and the user can control the switch of the discharge port 21 through the valve 8 to control whether concrete needs to be discharged according to actual needs.
