Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage pipelines, and particularly relates to a pipeline butt-joint device. Background Technique
[0002] The design and maintenance of the factory drainage system are crucial for maintaining the sanitation and safety of the factory environment. The system includes parts such as drainage pipelines, floor drains, manhole covers, sedimentation tanks or sewage treatment ponds, rainwater collection systems, inspection wells, overflow pipes, and drainage pumps. The drainage pipelines are responsible for transporting sewage and rainwater to the treatment facilities, and mainly use ribbed drainage pipelines (such as corrugated pipes, molded pipes, etc.). The ribbed drainage pipeline is a type of enhanced drainage pipeline, usually used to improve the strength and durability of the pipeline. There will be regular ribbed structures on the inner wall or outer wall of this kind of pipeline, and these ribs help to increase the stiffness of the pipeline, enabling it to withstand greater loads and pressures, while reducing the risk of deformation and rupture.
[0003] For the butt-joint of ribbed drainage pipelines, it is usually carried out by hammering. If a leather pad is added, the butt-joint is difficult. Excessive force is likely to cause the breakage of the pipe opening, and the difficult butt-joint is likely to prolong the overall construction period.
[0004] Therefore, we propose a pipeline butt-joint device to solve the problems raised above. Content of the Utility Model
[0005] (I) Technical Problems to be Solved
[0006] Aiming at the deficiencies of the prior art in the above-mentioned background technique, the purpose of the utility model is to provide a pipeline butt-joint device to solve the problems raised in the above-mentioned background technique.
[0007] (II) Technical Solutions
[0008] To achieve the above purpose, the utility model is realized through the following technical solutions:
[0009] A pipeline butt-joint device includes a cross frame. The cross frame includes two first cross frames and a second cross frame that are parallelly arranged and have the same structure. A lead screw is arranged between the first cross frame and the second cross frame along their width directions. The lead screw is rotationally connected to the first cross frame and is in threaded connection with the second cross frame;
[0010] A plurality of through grooves arranged along the length direction are opened at the top of the second cross frame. A butt rod is slidably installed inside the through grooves. A dial is arranged at the bottom of the butt rod, and an anti-disengagement plate with a size larger than the through grooves is arranged at the top of the butt rod.
[0011] Furthermore, two parallelly arranged limit retaining plates are arranged on the lead screw, and the two limit retaining plates are respectively located on both sides of the first cross frame.
[0012] Further, a turning handle is provided at one end of the lead screw close to the first cross frame.

[0017] (III) Beneficial effects
[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Detailed implementation manners
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. 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 "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions facing or away from the geometric center of a specific component. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Please refer to Figures 1-4 As shown, the present invention provides a pipe docking device, including a horizontal frame 1. The horizontal frame 1 includes two first horizontal frames 11 and second horizontal frames 12 that are parallel and have the same structure. A lead screw 2 is arranged between the first horizontal frame 11 and the second horizontal frame 12 along their width direction. The lead screw 2 is rotatably connected to the first horizontal frame 11 and is threadedly connected to the second horizontal frame 12. A plurality of through slots 3 arranged along its length direction are opened at the top of the second horizontal frame 12. An abutting rod 4 is slidably installed inside the through slot 3. A paddle 5 is arranged at the bottom of the abutting rod 4, and an anti - detachment plate 6 with a size larger than the through slot 3 is arranged at the top of the abutting rod 4. Two parallel limit stops 8 are arranged on the lead screw 2, and the two limit stops 8 are respectively located on both sides of the first horizontal frame 11. A turning handle 9 is arranged at one end of the lead screw 2 close to the first horizontal frame 11.
[0027] During pipe docking, the two ends of the pipes are made opposite. Then, the first horizontal frame 11 and the second horizontal frame 12 are respectively placed above the two pipes. Then, the horizontal frame 1 is moved downward so that the paddle 5 at the bottom of the abutting rod 4 is stuck in the rib slot between the ribs of the pipe. Then, the lead screw 2 is rotated through the turning handle 9. When the lead screw 2 rotates, it drives the second horizontal frame 12 to move towards the first horizontal frame 11, thereby driving the pipe below the second horizontal frame 12 to move into the pipe below the first horizontal frame 11, thus completing the pipe docking. This process is relatively gentle. Compared with the traditional manual knocking docking, the docking process is relatively gentle, and the force is controllable, reducing the occurrence of pipe - mouth breakage. At the same time, the multiple horizontally arranged abutting rods 4 can automatically adapt according to the pipe diameter to improve the scope of application.
[0028] As a preferred technical solution of the present utility model: Fixing mechanisms 7 are provided between the first cross frame 11 and the second cross frame 12 and the abutting rod 4. The fixing mechanism 7 includes a movable plate 71. A plate groove 72 for slidably connecting with the movable plate 71 is formed in the side wall of the second cross frame 12. The plate groove 72 communicates with the through groove 3. A plurality of equally spaced tooth grooves 73 are formed in the side wall of the abutting rod 4. A locking tooth 74 for engaging with the tooth groove 73 is fixed on the side wall of the movable plate 71.
[0029] When the bottom of each abutting rod 4 abuts in the rib groove of the pipeline, then the movable plate 71 is inserted into the plate groove 72, so that the locking tooth 74 on the movable plate 71 is inserted into the tooth groove 73 to fix the positions of the abutting rods 4, so as to prevent the positions of the abutting rods 4 from shifting during the pipeline docking process.
[0030] As a preferred technical solution of the present utility model: The fixing mechanism 7 further includes two fixing columns 75 fixed at both ends of the bottom wall of the plate groove 72. The fixing columns 75 pass through the movable plate 71 and are slidably connected thereto. An extension plate 76 is arranged on the fixing column 75. A return spring 77 is arranged between the extension plate 76 and the side wall of the movable plate 71. The return spring 77 is sleeved outside the fixing column 75. The arrangement of the fixing column 75, the extension plate 76 and the return spring 77 automatically resets after the staff loosens the movable plate 71, making it more convenient to use.
[0031] As a preferred technical solution of the present utility model: A handle 10 is arranged at one end of the movable plate 71 away from the plate groove 72 for the staff to pull the movable plate 71.
[0032] For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations; for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
