Description

Technical Field

[0001] This application relates to the technical field of conveying pumps, and in particular to a high-strength concrete long-distance pumping device. Background Art

[0002] A conveying pump, also known as a concrete pump, consists of a pump body and a conveying pipe. It is a machine that uses pressure to continuously convey concrete along the pipeline, and is mainly used in building construction, bridge construction, and tunnel construction. When a conveying pump needs to be processed, the connecting pipe needs to be fixed on the conveying pump, and then the machine is started to pump the concrete in the machine into the connecting pipe. When installing the connecting pipe, multiple people are required to align the connecting pipe with the connecting port, and the connecting pipe also needs to be lifted during connection. This approach will result in waste of manpower and time.

[0003] The Chinese utility model patent with the publication number CN217270763U discloses a concrete pumping device, which includes a pump body and a support device. A connecting port is provided on the surface of the pump body, and a connecting pipe is movably connected to the side wall of the connecting port. A support device is provided on the surface of the connecting pipe. The support device includes a backing plate, which is located directly below the connecting pipe. Two support plates are fixedly installed on the upper surface of the backing plate, and the two support plates are symmetrically distributed with respect to the center point of the backing plate. An auxiliary device is provided on the surface of the connecting pipe. The auxiliary device includes a support frame, which is located directly below the connecting pipe. A slider is slidably connected to the inner wall of the support frame, and a support ring is fixedly installed on the upper surface of the slider. The surface of the support ring is slidably connected to the outer surface of the connecting pipe. In this utility model, the pipeline is lifted and adjusted and connected by setting the support device.

[0004] In the process of implementing this application, at least the following problems exist in this technology. The lifting of the pipeline in this concrete pumping device is manually adjusted. Although this method can lift and adjust the pipeline, the efficiency is relatively low. For example, the concrete conveying pipeline is large and heavy, and manual lifting takes a lot of time. Therefore, a high-strength concrete long-distance pumping device is proposed to solve the problems raised above. Utility Model Content

[0012] Further, a guide rod for limiting is fixedly installed on the lower surface of the support base, and a guide groove adapted to the guide rod is provided on one side of the mounting frame close to the support base.

[0013] The beneficial effect of adopting the above further solution is that through the installation of the guide rod and the guide groove, it is ensured that the lifting mechanism stably adjusts the lifting of the conveying pipe, achieving the advantage of stable adjustment.

[0020] Furthermore, a docking pipe for docking with the material conveying pipe is fixedly communicated with the upper surface of the left end of the conveying pipe, and the top end of the docking pipe is conical.

Detailed implementation manners

[0032] Please refer to Figure 1 and Figure 2 . The high-strength concrete long-distance pumping equipment includes a pumping equipment body 1, a feeding pipe 2 installed on one side of the pumping equipment body 1, and a delivery pipe 4 arranged outside the pumping equipment body 1 for transporting high-strength concrete. A support structure and a lifting mechanism for lifting are arranged below the delivery pipe 4; the support structure includes a mounting frame 6 and a support base 7 fixedly installed outside the delivery pipe 4; the lifting mechanism includes a reduction motor 8 fixedly installed on the inner bottom wall of the mounting frame 6, a rotating shaft 10 rotatably installed on the mounting frame 6 and a rotating rod 9, and the rotating rod 9 is fixedly connected to the output shaft of the reduction motor 8 through a coupling, a driving gear 11 fixedly installed at one end of the rotating rod 9, a driven gear 12 fixedly installed at one end of the rotating shaft 10 and meshing with the driving gear 11, and a connecting member arranged at the other end of the rotating shaft 10 and connected to the lower surface of the support base 7. When the reduction motor 8 is started, the rotating shaft 10 is driven to rotate through the meshing of the driving gear 11 and the driven gear 12, and the rotating shaft 10 rotates to drive the docking pipe 5 to move upward through the connecting member. Since the top end of the docking pipe 5 is conical, it can be docked with the feeding pipe 2 and high-strength concrete can be transported over a long distance.

[0033] Please refer to Figure 2 and Figure 3 . In this embodiment, the connecting member includes a crank 13 fixedly installed at the other end of the rotating shaft 10 and a connecting rod 14 hinged to the other end of the crank 13 and the lower surface of the support base 7. A guide rod 15 for limiting is fixedly installed on the lower surface of the support base 7, and a guide groove 16 adapted to the guide rod 15 is formed on one side of the mounting frame 6 close to the support base 7. Through the installation of the guide rod 15 and the guide groove 16, it is ensured that the lifting mechanism stably adjusts the lifting of the delivery pipe 4, achieving the advantage of stable adjustment.

[0034] Among them, the upper surface of the left end of the conveying pipe 4 is fixedly connected and communicated with a docking pipe 5 that docks with the feeding pipe 2, and the top end of the docking pipe 5 is conical, which is convenient for docking with the feeding pipe 2 and also avoids the leakage of concrete. A vibration motor 3 is installed on the pumping equipment body 1. By installing the vibration motor 3, it is convenient for the rapid feeding of concrete. A screw conveyor 17 extending into it is arranged outside the conveying pipe 4. By installing the screw conveyor, it can not only convey the concrete but also stir the concrete to prevent the concrete from easily solidifying and hardening due to the evaporation of water during the pumping process.

[0035] It should be noted that the length of the guide rod 15 is greater than the lifting height of the conveying pipe 4, and the connection methods of the rotating shaft 10 and the rotating rod 9 with the mounting frame 6 are both bearing connections. The number of components in the lifting mechanism except the reduction motor 8 is two, and the two rotating rods 9, the two rotating shafts 10, and the two connecting pieces are symmetrically arranged.

[0036] Please refer to Figure 2 , in this embodiment, a support mechanism for support is arranged on the mounting frame 6. The support mechanism includes a hydraulic cylinder 18 fixedly installed on the inner bottom wall of the mounting frame 6 and a support block 19 fixedly installed on the output shaft of the hydraulic cylinder 18. The output end of the hydraulic cylinder 18 penetrates through the inside of the mounting frame 6.

[0037] Among them, the outer shape of the mounting frame 6 is concave-shaped. By installing the hydraulic cylinder 18 and the support block 19, the mounting frame 6 can be supported to ensure that the docking pipe 5 is stably docked with the feeding pipe 2.

[0038] The working principle of the above embodiment is as follows:

[0039] During use, the conveying pipe 4 is displaced below the feeding pipe 2 and the docking pipe 5 is aligned with the feeding pipe 2. Then, the reduction motor 8 is started, and the rotating shaft 10 is driven to rotate by the meshing of the driving gear 11 and the driven gear 12. The rotating shaft 10 rotates and drives the docking pipe 5 to move upward through the connecting piece. Since the top end of the docking pipe 5 is conical, it can be docked with the feeding pipe 2 and high-strength concrete can be conveyed over a long distance.
