Description

Technical Field

[0001] This application relates to the technical field of concrete conveying devices, and specifically relates to a 300-meter ultra-long-distance concrete pumping device. Background Art

[0002] A concrete pump, also known as a concrete delivery pump, consists of a pump body and a delivery pipe, and is a machine that continuously conveys concrete along a pipe using pressure. The concrete pump mainly drives a screw rod through an electric motor to convey the concrete into the pipe, and conveys the concrete to a predetermined position through the transportation of the pipe. However, when the concrete pump conveys the concrete through the pipe to an ultra-long distance of 300 meters and above, the concrete is likely to be blocked inside the pipe, causing the internal pressure of the pipe to rise, resulting in the rupture of the pipe and affecting the transportation of the concrete.

[0003] Therefore, there is an urgent need for a 300-meter ultra-long-distance concrete pumping device to solve the problem that ultra-long-distance concrete is likely to cause the rupture of the pipe. Utility Model Content

[0004] In view of the deficiencies of the prior art, this application provides a 300-meter ultra-long-distance concrete pumping device, which has the advantage of continuously pushing the concrete in the pipe, and solves the problem that ultra-long-distance concrete is likely to cause the rupture of the pipe.

[0005] To achieve the above object, this application provides the following technical solution: A 300-meter ultra-long-distance concrete pumping device, including a filter box, a delivery pump installed at the bottom of the filter box, a delivery pipe connected to the outlet of the delivery pump, and an outlet pipe connected to one side of the filter box. A pushing mechanism is arranged at the top of the delivery pipe, and a filtering mechanism is arranged inside the filter box;

[0006] The pushing mechanism includes a housing, a driving motor I, a connecting rod I, and a pushing blade. Several groups of the housings are welded to the top of the delivery pipe. The driving motor I is installed on the back side of the housing. One end of the connecting rod I is fixedly connected to the output end of the driving motor I, and the other end of the connecting rod I is rotatably connected to the inner side of the housing. The pushing blade is fixedly connected to the outer surface of the connecting rod I by screws.

[0007] When the pushing blade rotates, it continuously pushes the concrete inside the delivery pipe forward, giving the concrete continuous thrust, preventing the concrete from accumulating inside the delivery pipe, preventing the delivery pipe from rupturing, and enabling the concrete to be continuously and stably transported.

[0008] Preferably, the middle of the connecting rod I is a cylindrical structure, and the outer side is a uniformly distributed rectangular plate body.

[0009] Preferably, several groups of the pushing mechanisms are installed on the top of the delivery pipe at equal intervals.

[0010] Preferably, the filtering mechanism includes a second driving motor, a second connecting rod, a support frame, and a filter screen. The second driving motor is installed on the front of the filtering box. Both ends of the support frame are respectively fixedly connected to the second connecting rod by screws. One group of the support frames is fixedly connected to the output end of the second driving motor by screws, and the other group of the support frames is rotatably connected to the inner side of the filtering box. A plurality of groups of filter screens are arranged on the outer side of the support frame.

[0011] Preferably, a support block is welded inside the filtering box, and an arc-shaped groove adapted to the support frame is formed in the support block.

[0012] Preferably, the horizontal height of the top of the support frame is higher than the horizontal height of the top of the support block.

[0013] In summary, the present application includes at least one of the following beneficial effects:

[0014] 1. For the 300-meter ultra-long-distance concrete pumping device, when the concrete pumped by the delivery pump is conveyed into the delivery pipe, the first driving motor drives the pushing blade to rotate through the first connecting rod. When the pushing blade rotates, the concrete inside the delivery pipe is continuously pushed forward, giving continuous thrust to the concrete, preventing the concrete from accumulating inside the delivery pipe, preventing the delivery pipe from bursting, and enabling the concrete to be continuously and stably conveyed.

[0015] 2. For the 300-meter ultra-long-distance concrete pumping device, when the concrete enters the filtering box, when the support frame drives the filter screen to rotate, the filter screen filters the large stones in the concrete, preventing the large stones from blocking the pipeline and enabling the concrete delivery pump to stably convey the concrete.

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0023] Please refer to Figures 1-4 , a 300-meter ultra-long-distance concrete pumping device, including a filter box 1, a delivery pump 2 installed at the bottom of the filter box 1, a delivery pipe 3 connected to the outlet of the delivery pump 2, and a discharge pipe 4 connected to one side of the filter box 1. Concrete enters the side of the filter box 1 away from the filter box 1. A pushing mechanism is provided at the top of the delivery pipe 3, and a filtering mechanism is provided inside the filter box 1. The large stones in the concrete are filtered by the filtering mechanism, and the filtered large stones are discharged from the discharge pipe 4. The filtered concrete is transported into the delivery pipe 3 through the delivery pump 2, and the concrete is transported to a predetermined position through the delivery pipe 3.

[0024] Specifically, the pushing mechanism includes a housing 111, a driving motor 112, a connecting rod 113, and a pushing blade 114. Several groups of housings 111 are welded to the top of the delivery pipe 3. The driving motor 112 is installed on the back side of the housing 111. One end of the connecting rod 113 is fixedly connected to the output end of the driving motor 112, and the other end of the connecting rod 113 is rotatably connected to the inside of the housing 111. The middle of the connecting rod 113 is a cylindrical structure, and the outside is a uniformly distributed rectangular plate body. The pushing blade 114 is fixedly connected to the outer surface of the connecting rod 113 by screws. Several groups of pushing mechanisms are installed on the top of the delivery pipe 3 at equal intervals.

[0025] Through the above technical solution, when the concrete is transported inside the delivery pipe 3, the driving motor 112 is started. The driving motor 112 drives the pushing blade 114 to rotate through the connecting rod 113. When the pushing blade 114 rotates, the concrete inside the delivery pipe 3 is continuously pushed forward, giving the concrete continuous thrust, preventing the concrete from accumulating inside the delivery pipe 3, preventing the delivery pipe 3 from bursting, and enabling the concrete to be continuously and stably transported.

[0026] Specifically, the filtering mechanism includes a second driving motor 211, a second connecting rod 212, a support frame 213, and a filter screen 214. The second driving motor 211 is installed on the front of the filtering box 1. Both ends of the support frame 213 are fixedly connected to the second connecting rod 212 by screws. One set of the support frames 213 is fixedly connected to the output end of the second driving motor 211 by screws, and the other set of the support frames 213 is rotatably connected to the inner side of the filtering box 1. A number of groups of filter screens 214 are arranged on the outer side of the support frame 213. A support block 215 is welded on the inner side of the filtering box 1. The support block 215 is provided with an arc-shaped groove adapted to the support frame 213. The horizontal height of the top of the support frame 213 is higher than the horizontal height of the top of the support block 215.

[0027] Through the above technical solution, when the concrete enters the side of the filtering box 1 far from the filtering box 1, the second driving motor 211 is started. The second driving motor 211 drives the support frame 213 to rotate through the second connecting rod 212. When the support frame 213 rotates, it drives the filter screen 214 to rotate. When the filter screen 214 rotates, it filters the large stones in the concrete, so that the large stones will not block the pipeline. The filtered large stones are discharged from the discharge pipe 4, and the filtered concrete is conveyed into the interior of the conveying pipe 3 by the conveyor pump 2, and the concrete is conveyed to a predetermined position through the conveying pipe 3.

[0028] During use, when the pushing blade 114 rotates, it continuously pushes the concrete inside the conveying pipe 3 forward, giving the concrete continuous thrust, preventing the concrete from accumulating inside the conveying pipe 3, preventing the conveying pipe 3 from bursting, and enabling the concrete to be continuously and stably conveyed.
