Description

Technical Field

[0001] The invention relates to the technical field of hoisting devices, and in particular to a construction hoisting device for a sewage pipe. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipes have a wide range of applications. In the process of urban sewage treatment, it is necessary to lay a sewage pipe network.

[0003] The diameter of the most common converging pipes in the sewage network is 300mm. As the flow rate increases, the pipe diameter will also become larger. Common sewage pipes are generally cement pipes and plastic corrugated pipes. During the construction process, the pipes need to be docked with each other in the pre-excavated ditch in the correct posture. Among the existing construction equipment, most of the pipes are hoisted with tire cranes. However, there are some construction areas in the city where tire cranes cannot be used, or in the later maintenance, for the replacement of a single section of the pipe, the use of tire cranes in the construction increases the cost of a single maintenance. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a construction hoisting device for sewage pipes, comprising four support rods, two support rods in a group, each group of support rods arranged in an "eight" shape, two cross bars arranged side by side on the upper part of the support rods, the ends of the cross bars inserted in the upper part of the support rods, and a mobile platform rollingly arranged on the cross bars. The support rods and the cross bars constitute the main frame structure of the device, and the mobile platform is used to lift and transport the pipes.

[0005] The mobile platform includes two connecting plates that are symmetrically arranged in the upper and lower parts. The two sides of the connecting plates are folded 90 degrees to form side plates, and a rotating shaft is provided on the side plates. The rotating shaft is provided with track wheels, and the track wheels cooperate with the cross bar. The lower end of the mobile platform is fixedly connected to the chain hoist. The mobile platform adopts a symmetrical upper and lower structure, clamped on the cross bar, and the chain hoist is used to lift the pipeline. In this scheme, a manual operation method is adopted, that is, the pipeline is tied to the chain hoist, and then the pipeline is lifted manually, and the position of the mobile platform is controlled by pushing. Finally, the position under the pipeline is precisely adjusted by manpower to achieve the installation of the pipeline. The structure of the device is greatly simplified in this scheme, making the device simple and easy to operate, especially in the working area where large lifting equipment cannot be used.

[0006] Preferably, a plurality of first connecting rods are fixedly connected at the same height between two supporting rods in the same group. The supporting rods in the same group are connected to form an integral structure.

[0007] Preferably, a connecting ear is fixedly connected to the support rod, and the end of the first connecting rod leans on the upper side of the connecting ear. A first bolt and nut are fixedly connected through the connecting ear. By removing the first bolt and nut, the first connecting rod and the support rod can be separated. This setting enables the split transportation of the support rod. At the same time, the first bolt and nut belong to a conventional connection method and are easier to operate.

[0008] Preferably, a screw rod is fixedly connected to the end of the cross bar. The screw rod penetrates into a through hole preset at the upper end of the support rod, and a fixing nut is threadedly engaged with the screw rod. That is, the cross bar and the support rod are also connected in a detachable manner, which is conducive to the separation between the cross bar and the support rod and thus facilitates transportation.

[0009] Preferably, a sliding sleeve is sleeved on the cross bar, and a second connecting rod is fixedly connected between adjacent sliding sleeves. The sliding sleeve and the second connecting rod are provided to improve the support stability of the cross bar.

[0010] Preferably, a fixing bolt is threadedly connected to the sliding sleeve, and the fixing bolt abuts against the cross bar. Tightening the fixing bolt realizes the fixation of the sliding sleeve. This method also facilitates the removal of the sliding sleeve and the second connecting rod from the cross bar and is conducive to the transportation of the device.

[0011] Preferably, a number of second bolt and nut pairs are fixedly connected through the two connecting plates. By removing the second bolt and nut pairs, the upper and lower parts of the moving platform can be separated, which is convenient for disassembly and assembly and also conducive to the transportation of the device.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention has a simple structure, is easy to operate, can be erected and constructed on site, has a low use cost, and can also operate in areas where a wheeled crane cannot enter.

[0014] 2. The present invention adopts a detachable design, such as between the support rod and the cross bar, between the moving platform and the cross bar, etc. That is, the device is transported in the form of components during transportation and assembled at the construction site, which is conducive to the use of the device.

[0022] The present invention will be further clarified below in conjunction with the drawings and specific implementation manners. It should be understood that the following specific implementation manners are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0023] As Figures 1 to 4 shown, a construction hoisting device for sewage pipe pipelines includes four support rods 1, and two support rods 1 are in a group. Each group of support rods 1 is arranged in a "V" shape, that is, the lower part of the device is large and the upper part is small, which can improve the stability of the support. Two cross bars 5 are arranged side by side at the upper part of the support rods 1, and the ends of the cross bars 5 are inserted into the upper parts of the support rods 1. The arrangement of the cross bars 5 makes the two groups of support rods 1 form a whole, that is, the cross bars 5 cooperate with the support rods 1 to form the overall framework of the device. A moving platform 3 is rollingly arranged on the cross bars 5. The moving platform 3 is used for hoisting and moving the pipeline.

[0024] The moving platform 3 includes two connecting plates 31 arranged symmetrically up and down. The two sides of the connecting plates 31 are folded 90° to form side plates, that is, the connecting plates 31 are in a "U" shape structure, and a rotating shaft 34 is penetrated through the side plates. Here, a rotating shaft 34 is inserted through each connecting plate 31. A track wheel 32 is arranged on the rotating shaft 34. That is, a groove is arranged in the middle of the roller of the track wheel 32, so that the track wheel 32 can better hold the cross bar. At the same time, two track wheels 32 are arranged on each rotating shaft 34, which respectively rollingly cooperate with the two cross bars 5. The lower end of the moving platform 3 is fixedly connected to the chain hoist 4. The chain hoist 4 is manually operated. Therefore, when hoisting the pipeline, the pipeline needs to be tied and fixed to the chain hoist 4, and then the pipeline is lifted by hand, that is, it is pushed manually again, so that the moving platform 3 moves on the cross bars 5 to the excavated ditch, and then the chain hoist 4 is operated again to lower the pipeline. During the process, the attitude of the pipeline is adjusted manually to ensure the correct placement of the pipeline. This device has the advantages of simple structure and convenient operation, and can be used as a replacement in scenarios where large hoisting equipment cannot be used.

[0025] A number of first connecting rods 2 are fixedly connected at the same height between two support rods 1 in the same group. The use of the first connecting rods 2 makes the support rods 1 in the same group into a whole, which is used to improve the stability of the support.

[0026] A connecting ear 7 is fixedly connected to the support rod 1. The support rod 1 is an angle steel, and the connecting ear 7 is welded and fixed inside the angle steel. And the end of the first connecting rod 2 is placed above the connecting ear 7. A first bolt and nut 6 is inserted and fixedly connected to the connecting ear 7. That is, the first bolt and nut 6 simultaneously passes through the through holes reserved at the end of the connecting rod 7 and the first connecting rod 2 to realize the fixed connection between the two. In this connection method, a common connection method is adopted, which can facilitate the disassembly and assembly of the support rod 1 and the first connecting rod 2. When transporting, they are disassembled to facilitate the disassembly of the device.

[0027] A screw rod 11 is fixedly connected to the end of the cross bar 5. The screw rod 11 penetrates into the through hole preset at the upper end of the support rod 1, and a fixing nut 10 is threadedly engaged with the screw rod 11. In this way, it is simultaneously realized that the cross bar 5 and the support rod 1 are connected by the screw rod 11 and the fixing nut 10, and it is also convenient for disassembly, assembly and transportation.

[0028] A sliding sleeve 8 is sleeved on the cross bar 5. A second connecting rod 12 is fixedly connected between adjacent sliding sleeves 8. Through the sliding sleeve 8 and the second connecting rod 12, the two cross bars 5 can be made into a whole, thereby improving the stable movement of the moving platform 5.

[0029] A fixing bolt 9 is threadedly connected to the sliding sleeve 8, and the fixing bolt 9 abuts against the cross bar 5. That is, after the fixing bolt 9 is tightened, the end of the fixing bolt 9 abuts against the side wall of the cross bar 5 to realize the fixation of the sliding sleeve 8, and this fixing method is also convenient for the disassembly and assembly of the device.

[0030] A number of second bolt and nut 33 are inserted and fixed through two connecting plates 31. Removing the second bolt and nut 33 can divide the moving platform 3 into two parts. The first bolt and nut 33 is also a component for installing the cross bar 5 on the moving platform 3. Therefore, the moving platform 3 can also be disassembled and assembled for convenient transportation.

[0031] The technical means disclosed in the solution of the present invention is not limited to the technical means disclosed in the above embodiments, but also includes the technical solutions composed of any combination of the above technical features.
