[0021] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:
[0022] Embodiment 1
[0023] like Figures 1 to 5 As shown, a municipal drainage pipe docking traction device described in the utility model comprises a support frame 1, a moving wheel 2 is arranged at the bottom of the support frame 1, and the moving wheel 2 can be driven by a motor, such as using a chain sprocket to transmit the power between multiple moving wheels 2, so as to realize the flexible movement of the support frame 1 along the pipe installation direction, improve the convenience of construction operation, and reduce labor intensity; a double-drum winch 3 is arranged on the top of the support frame 1, and the setting of the double-drum winch 3 can ensure the balance of force on both sides of the pipe during movement through bidirectional pulling, reduce the probability of deviation during the pulling process of the pipe, and ensure the smooth assembly and connection of the pipe; a positioning plate 4 is arranged on the support frame 1 on one side of the double-drum winch 3, which can be raised and lowered, and the positioning plate 4 is arranged along the direction of pipe assembly installation, and the positioning plate 4 is used to align the installed pipe located below The fixing of the pipeline can not only ensure the stability of the installed pipeline, but also ensure the stability of the supporting frame 1 during operation; the positioning plate 4 is preferably controlled by a cylinder or an oil cylinder to control its lifting and lowering, and the downward thrust of the cylinder or the oil cylinder can be used to achieve close contact between the positioning plate 4 and the pipeline below; the end of the wire rope 8 on the double-drum winch 3 is connected to a pulling frame 5, and the pulling frame 5 is used to be placed at the end of the pipeline to be pulled, that is, the end with a larger opening diameter, wherein the size of the pulling frame 5 is adjustable to meet the use of pipelines of various sizes and expand its scope of application; before this, a positioning card plate 6 is provided at one end close to the double-drum winch 3, and the positioning card plate 6 is used to extend into the interior of the pipeline to be pulled, and by adjusting the size of the pulling frame 5, the positioning card plate 6 is closely abutted against the inner wall of the pipeline to be pulled, thereby ensuring a close connection between the pulling frame 5 and the pipeline. When working, first release the wire rope 8 on the double-drum winch 3, move the pulling frame 5 to the end of the pipe to be pulled and connect with the pipe to be pulled, and finally adjust the straightness of the pipe and control the double-drum winch 3 to reel in. The whole process is easy to operate, simple in structure and highly practical.
[0024] Furthermore, in the present embodiment, the positioning plate 4 is an arc-shaped structure so as to match and fit with the arc surface of the pipeline, and two first guide pulleys 7 are arranged on both sides of the positioning plate 4 in the horizontal direction. The first guide pulleys 7 are arranged to provide guidance for the wire rope 8, and at the same time, the wire rope 8 can be horizontally located on both sides of the positioning plate 4 after being released from the double-drum winch 3, and can be located on both sides of the pipeline to be pulled and remain horizontal after being connected to the pulling frame 5, thereby ensuring horizontal force on the pipeline to be pulled; wherein, the wire rope 8 passes under one first guide pulley 7 and comes out from above the other first guide pulley 7.
[0025] Furthermore, in this embodiment, the pulling frame 5 includes a cross-shaped frame 5-1, and the four ends of the frame 5-1 are adjustable and provided with telescopic rods 5-2. The frame 5-1 is threaded with locking bolts, and the adjusted telescopic rods 5-2 are locked and fixed by the locking bolts; the positioning clamp 6 is vertically arranged on the telescopic rod 5-2; when the pulling frame 5 is in use, its size is larger than the diameter of the large end of the pipeline, so as to ensure that the pulling frame 5 can smoothly push the pipeline to move when the force is applied. Among them, a fixing ring 9 is arranged on the horizontally arranged telescopic rod 5-2, and the ends of the horizontally arranged telescopic rod 5-2 are rotatably provided with a reversing pulley 10. After the end of the wire rope 8 is connected to the fixing ring 9, it is wound out from the wheel groove of the reversing pulley 10, so as to reduce the friction between the wire rope 8 and the end of the telescopic rod 5-2 when the force is applied, and extend the service life of the wire rope 8, i.e., the telescopic rod 5-2.
[0026] Embodiment 2
[0027] In this embodiment, sliding rollers 12 are symmetrically arranged on the bottom support beam 11 at one end of the support frame 1 away from the positioning plate 4, and the distance between the two opposite sliding rollers 12 is adjustable. The sliding rollers 12 can provide assistance for the movement of the pipeline to be pulled, reduce the friction between the pipeline and the ground when it moves, and ensure the smooth assembly and connection of the pipeline. The spacing of the sliding rollers 12 is adjustable, and after the pipelines are docked, the spacing between the sliding rollers 12 on both sides can be increased to achieve the separation contact between the sliding rollers 12 and the bottom of the pipeline, which facilitates the movement of the support frame 1.
[0028] Furthermore, the sliding roller 12 is rotatably arranged on the support shaft 13, and the support shaft 13 is arranged on the support block 14; wherein a receiving cavity 15 is opened inside the support beam 11, and the support block 14 is elastically arranged in the receiving cavity 15. Preferably, each support shaft 13 is slidably arranged in the receiving cavity 15, and a return spring 16 is sleeved on the outside of the support shaft 13 between the inner wall of the receiving cavity 15 and the support block 14 to assist the support block 14 in resetting; a driving block 17 is slidably arranged in the receiving cavity 15, and one end of the driving block 17 extends from one end of the support beam 11, and the end surface of the support block 14 in contact with the driving block 17 is an inclined surface, so that as the driving block 17 moves, a thrust is generated on the support block 14, and the support shaft 13 is pushed out of the receiving cavity 15, so as to achieve the purpose of reducing the distance between the symmetrical sliding rollers 12; a moving groove communicating with the inside of the receiving cavity 15 is opened at the top of the support beam 11, and a pulling plate 18 is arranged on the driving block 17 , a group of second guide pulleys 19 are arranged on the pulling plate 18 in the vertical direction. The second guide pulley 19 on the top of each group is preferably on the same horizontal line as the first guide pulley 7, and the second guide pulley 19 on the bottom is on the same horizontal line as the reversing pulley 10, so as to ensure the horizontal force of the pulled pipe. During operation, as the double-drum winch 3 is tightened, the wire rope 8 will pull the pulling plate 18 to move, thereby driving the driving block 17 to enter the accommodating chamber 15 and generate thrust on the support block 14, pushing the support shaft 13 out, thereby reducing the distance between the two symmetrical sliding rollers 12, providing support for the bottom of the pipe to be paired, and allowing the pipe to slide smoothly along the sliding roller 12 to the front pipe to complete the docking operation. After docking, the double-drum winch 3 releases the wire rope 8 again, and the support block 14 pushes the driving block 17 to reset under the restoring force of the reset spring 16. The distance between the symmetrical sliding rollers 12 increases, reserving space for the movement of the support frame 1. In order to ensure the smooth reset of the driving block 17, such as Figure 3 As shown, in this embodiment, a slide bar 20 is provided in the accommodating chamber 15, and the slide bar 20 is slidably connected with the slide hole on the driving block 17, and a fixing plate 21 is provided on the slide bar 20, and a buffer spring 22 is provided between the fixing plate 21 and the driving block 17. When the pipeline is assembled, the elastic force of the compressed buffer spring 22 is released, and at this time, under the action of the reset spring 16 and the buffer spring 22, the driving block 17 is quickly reset. In this embodiment, the elastic force of the reset spring 16 and the buffer spring 22 is smaller than the friction force between the wire rope 8 and the second guide pulley 19 during operation, so when the wire rope 8 is tensioned, it will drive the pulling plate 18 to move, thereby realizing the adjustment of the spacing between the sliding rollers 12.
[0029] Furthermore, each sliding roller 12 is rotatably provided with a roller 23 at one end away from the support shaft 13. The setting of the roller 23 can realize the movement of the support frame 1 by utilizing the sliding contact between the roller 23 and the pipe wall when the pipe diameter is slightly larger; it can avoid the end of the sliding roller 12 directly contacting the pipe wall to cause greater wear, or being unable to move due to greater friction; wherein, the roller 23 is preferably arranged to slightly protrude from the end of the sliding roller 12, which neither occupies excessive space nor fails to play a corresponding role.
[0030] Furthermore, the sliding roller 12 is sleeved on the outside of the support shaft 13, and a spring 24 is rotatably arranged between the inside of the sliding roller 12 and the end of the support shaft 13, and a guide rod 25 coaxially arranged with the sliding roller 12 is passed through the inside of the spring 24, and the end of the guide rod 25 away from the sliding roller 12 is movably passed through a guide hole 26 opened on the support shaft 13; such an arrangement can not only ensure the normal rotation of the sliding roller 12, but also when the support frame moves and encounters a large diameter of the pipeline, the force compression of the sliding roller 12 can be used to further expand the distance between the two sliding rollers 12, thereby facilitating the movement of the support frame 1.
[0031] Furthermore, an electric hoist 27 that can move along its length is provided on the support frame 1 above the sliding roller 12. A suspension rod 28 is provided on the wire rope of the electric hoist 27. The suspension rod 28 is used to extend into the front end of the pipeline, that is, the end with a small diameter, and can lift the front end of the pipeline to facilitate its position adjustment. It is also helpful to place it above the sliding roller 12 located at the end. As the double-drum winch 3 tightens the sliding roller 12 and moves out, it is convenient for pulling and moving the pipeline. After the position of the pipeline is adjusted, the suspension plate can be taken out and reset to avoid affecting the movement of the pipeline. The electric hoist 27 can be slidably connected to the I-beam provided on the support frame 1, and a driving wheel driven by a motor is provided on it to drive the electric hoist 27 to move.
[0032] When the utility model is in operation, the support frame is first placed in the foundation pit where the pipeline needs to be docked, so that the pipeline is located in the middle of the support frame 1, and then the double-drum winch 3 is turned on to release the wire rope 8, and the positioning plate 4 is controlled to descend and clamped on the pipeline below; then the size of the pulling frame 5 is adjusted, and the pulling frame 5 is connected with the large end of the pulling pipeline. During this period, the electric hoist 27 can be used to adjust it according to the position of the pipeline, and finally the double-drum winch 3 is turned on to reel in the wire rope 8 to drive the pipeline to move, until the pipeline moves to the end position of the previous pipeline to complete the docking; due to the large diameter of the pipeline end, the large end of the pipeline usually will not move into the support frame 1, so the position of the pipeline end will not affect its overall pulling; after the pulling is completed, the wire rope 8 is released, the wire rope 8 loses tension, the sliding roller 12 is reset, and the support frame 1 is controlled to move to the next position.
