Description

Technical Field

[0001] The present invention relates to the technical field of rain and sewage pipe construction, and particularly to a rain and sewage pipe docking device. Background Art

[0002] Rain and sewage pipes are drainage pipes for sewage or rainwater in municipal drainage pipelines. Drainage pipes are divided into plastic drainage pipes, concrete pipes (CP), and reinforced concrete pipes (RCP).

[0003] During the construction process, the rain and sewage pipes are lowered into the excavated trench. Generally, one end of the rain and sewage pipe is larger, and then the rain and sewage pipes placed in the trench are connected end to end. In traditional construction, usually after the rain and sewage pipes are placed, construction crowbars are used to push the rain and sewage pipes to achieve the docking operation. However, for concrete pipes, during the prying process, the concrete pipes may be damaged, which affects the construction speed and increases the construction cost. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a rain and sewage pipe docking device, which includes a first frame and a second frame. An electric cylinder is provided on the second frame. One end of the electric cylinder extends with a telescopic rod. One end of the telescopic rod is fixedly connected with a channel steel member. Two guiding wheels distributed up and down are rotatably arranged inside the channel steel member. A driving motor is arranged below the electric cylinder, and the output end of the driving motor is fixedly connected with a winding roller. The action of the electric cylinder can realize the extension or retraction of the telescopic rod, and at the same time, the driving motor is powered on to realize the rotation of the winding roller.

[0005] Two support plates are provided above the first frame. Two clamping rollers are arranged between the two support plates. A supporting belt is clamped and wound on the two clamping rollers. The other end of the supporting belt bypasses the guiding wheel in an S shape and then is wound on the winding roller. During construction, the rain and sewage pipe is placed on the supporting belt. Under the action of gravity, the rainwater pipe rolls to the drooping part of the supporting belt. The electric cylinder is started, and the telescopic rod extends and retracts, which changes the position of the rain and sewage pipe between the first frame and the second frame. At this time, cooperating with the operation of the driving motor, the winding roller rotates to further change the height of the rain and sewage pipe. Through the operations in two directions, the rain and sewage pipe can be correctly placed into the trench to complete the docking of the rain and sewage pipes pre-placed in the trench.

[0006] Preferably, a second cross plate is fixedly connected to the second frame, and the driving motor is fixedly connected to the second cross plate. The second cross plate is fixedly connected to the lower part of the second frame.

[0007] Preferably, both ends of the electric cylinder are fixedly connected with connecting blocks, and the connecting blocks are fixedly connected to the second frame. The connecting blocks are fixedly connected to the upper cross bar of the second frame.

[0008] Preferably, a first transverse plate is fixedly connected to the first frame, and the support plate is fixedly connected to the first transverse plate.

[0009] Preferably, the end of the clamping roller is fixedly connected with a rotating shaft, and the rotating shaft is rotatably engaged on the support plate.

[0010] Preferably, a crank is provided on the rotating shaft in a sliding manner, a tooth groove is axially provided on the side wall of the rotating shaft, and a convex tooth is provided on the crank, and the convex tooth fits in the tooth groove, and a convex column is fixedly connected to the side wall of the supporting plate. That is, the crank can slide axially on the rotating shaft, and when the crank approaches the supporting plate, it will be blocked by the convex column as the crank rotates, thereby limiting the rotation of the crank, and when the crank slides axially away from the supporting plate, it can rotate without restriction, and the rotating shaft of the crank realizes the rotation of the two clamping rollers.

[0011] Furthermore, after the end of the support belt is inserted between the two clamping rollers, the support belt is rotated and wound several times, and then the crank is pushed toward the support plate to limit its rotation. At this time, after the support belt is subjected to force, it is squeezed at the clamping roller due to being wound several times, and friction is generated. The support belt cannot slide off the clamping roller, and the end of the support belt located at the clamping roller is fixed. If the support belt is to be loosened, only the crank can be axially slid to get rid of the restriction of the blocking column. This fixing method is simple to operate, and the end of the support belt is firmly fixed. It is convenient to pull the support belt out from under the rainwater and sewage pipe after it is installed.

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

[0013] 1. Place the rainwater and sewage pipes on the support belt, and then control the position of the rainwater and sewage pipes through the electric cylinder and the drive motor, and lower the rainwater and sewage pipes into the groove in the correct posture to achieve docking operation, which has the advantages of easy operation and not easy to damage the rainwater and sewage pipes.

[0014] 2. One end of the support belt is clamped and wound by the clamping roller, and the rotation of the clamping roller is limited by the convex column. If the clamping roller needs to be rotated, the crank handle can be slid to offset the convex column. It has the advantages of simple operation and convenient fixing and releasing of the towing clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further clarified below in conjunction with the accompanying 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 accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. Embodiment 1

[0022] Combined with Figure 1 and Figure 2 As shown, a rain and sewage pipeline docking device includes a first frame 1 and a second frame 4. The structures of the first frame 1 and the second frame 4 are the same, and both are composed of transverse, longitudinal and vertical rods. When in use, the first frame 1 and the second frame are respectively arranged on both sides of the trench. An electric cylinder 12 is arranged on the second frame 4, and a telescopic rod 11 extends from one end of the electric cylinder 12, that is, the direction of the telescopic rod 11 is towards the trench. One end of the telescopic rod 11 is fixedly connected to a channel steel part 10. Looking down from above, the cross-sectional shape of the channel steel part 10 is the same as that of the channel steel. Two guide wheels 9 arranged up and down are rotatably arranged inside the channel steel part 10. A driving motor 7 is arranged below the electric cylinder 12, and the output end of the driving motor 7 is fixedly connected to a winding roller 6. When the driving motor 7 works, it drives the winding roller 6 to rotate.

[0023] In addition, a storage battery, a control unit, etc. are also arranged on the second frame 4. This structure is not shown in the figure and is used for the power supply and control of the driving motor 7 and the electric cylinder 12, and can increase the overall weight of the device and provide the stability of the device.

[0024] Two support plates 16 are arranged above the first frame 1. Two clamping rollers 18 are arranged between the two support plates 16. A supporting belt 3 is clamped and wound around the two clamping rollers 18, that is, the end of the supporting belt 3 is inserted between the two clamping rollers 18, and then the two clamping rollers 18 rotate several circles, so that the supporting belt 3 is wound several circles. When the supporting belt 3 is stressed, if the clamping rollers 18 do not rotate, the supporting belt 3 is fixed by the frictional force generated by its own mutual extrusion. The other end of the supporting belt 3 bypasses the guide wheel 9 in an S shape and then is wound around the winding roller 6. When the winding roller 6 rotates, the supporting belt 3 is wound or released.

[0025] When in use, the rain and sewage pipe is pre-placed on the supporting belt 3, and then the position of the rain and sewage pipe is adjusted by the driving motor 7 and the electric cylinder 12, and the rain and sewage pipe is placed in the trench to complete the docking operation with the rain and sewage pipe in the trench.

[0026] As Figure 2 shown, a second cross plate 8 is fixedly connected to the second frame 4, the driving motor 7 is fixedly connected to the second cross plate 8, a motor support is arranged on the side wall of the driving motor 7, and the lower end of the motor support is fixedly connected to the second cross plate 8 by means of bolts and nuts. Both ends of the electric cylinder 12 are fixedly connected with connecting blocks 5, the connecting blocks 5 are fixedly connected to the second frame 4, and the connecting blocks 5 are fixedly connected to the second frame 4 by welding.

[0027] As Figure 1 shown, a first cross plate 2 is fixedly connected to the first frame 1, and the support plate 16 is fixedly connected to the first cross plate 2.

[0028] As Figure 3 shown, a rotating shaft 14 is fixedly connected to the end of the clamping roller 18, the rotating shaft 14 is rotationally matched with the support plate 16, and the axis of the rotating shaft 14 is located at the midpoint of the center line connecting the centers of the two clamping rollers 18.

[0029] A rocker 13 is slidably fitted on the rotating shaft 14. A tooth groove 15 is axially arranged on the side wall of the rotating shaft 14, and a convex tooth is arranged on the rocker 13, and the convex tooth is fitted in the tooth groove 15, that is, the rocker 13 slides axially on the rotating shaft 14 through the tooth groove 15 and the convex tooth. A convex column 17 is fixedly connected to the side wall of the support plate 16. When the rocker 13 slides axially towards the support plate 16 and rotates, it is restricted by the convex column 17, and the clamping roller 18 is fixed. If the rocker 13 slides axially away from the support plate 16, that is, the rocker 13 and the convex column 17 are misaligned, the rocker 13 can be rotated. This structure has the advantages of convenient operation for fixing the end of the supporting belt 13 and convenient release. Embodiment 2

[0030] This embodiment is based on Embodiment 1. As Figure 4 shown, a connecting rod 19 is additionally provided between the first frame 1 and the second frame 4. When in use, the connecting rod 19 straddles above the trench. Using the connecting rod 19 can make the device integrated, improve the support stability, and avoid the problem that the first frame 1 or the second frame 4 overturns after the supporting belt 3 is stressed.
