Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to an auxiliary docking device for a municipal drainage pipeline. Background Art

[0002] Municipal water supply and drainage simply refers to the city's water supply (tap water) and drainage (rainwater, sewage, etc.). Municipal water supply and drainage pipelines are devices for liquids or fluids with solid particles connected by pipes, pipe connectors and valves.

[0003] In the prior art, there is a docking device for municipal drainage pipes disclosed in patent CN219360365U. When the pipes need to be docked, the pipes are placed on the top of the lower clamping block, and motor 2 is started. The output end of motor 2 drives the screw to rotate, and the screw drives the lifting block to move downward, and the lifting block drives the upper clamping block to move downward. The pipe is fixed by the lower clamping block and the upper clamping block, and motor 1 is started. The output end of motor 1 drives the forward and reverse screws to rotate, and the forward and reverse screws drive the movable sleeve, the tooling block, the lower clamping block and the upper clamping block to move inward. When the pipes on both sides are in contact, the pipe docking is completed. During this period, the staff does not need to consume energy. It has the advantages of automatic and high efficiency, does not require manual hand-held tools to operate, does not cause burden on the human arm, does not cause soreness and fatigue, and improves the working efficiency of the docking device.

[0004] In the above patented technology, two motors are used to drive the lifting screw and the translational screw respectively, so as to achieve the clamping and docking of the pipe, avoid manual rotation operation, and reduce the labor intensity of manual work. However, since the anti-collision block and the tooling block are a whole, the central hole of the anti-collision block fits the outer surface of the pipe, and the tooling block is also located on the outside of the pipe. The whole is pre-inserted from the connection between the two pipes. After the pipe docking is completed, the whole device needs to be slid out along the unclosed end of the pipe and removed. If the pipe is long, the sliding time of the whole device is long, and it is difficult to remove it quickly, which reduces the use effect of the auxiliary docking device of the municipal drainage pipe.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1:

[0023] like Figure 1-Figure 4 As shown, the utility model provides an auxiliary docking device for a municipal drainage pipe, comprising two fixed blocks 2, a fixed shaft 5 is fixedly connected between the relative outer surfaces of the two fixed blocks 2, and a rotating block 1 is rotatably connected to the outer surface of the fixed shaft 5.

[0024] The fixing component 3 comprises two mounting blocks 301, the two mounting blocks 301 are respectively fixedly connected to the outer surfaces of the rotating block 1 and the two fixing blocks 2, the inner surfaces of the two mounting blocks 301 are respectively fixedly connected with motors 302, the output ends of the two motors 302 rotate and penetrate the inner surfaces of the two mounting blocks 301, the output ends of the two motors 302 are respectively fixedly connected with first threaded rods 303, the outer surfaces of the two mounting blocks 301 are respectively provided with electric telescopic rods 305, the telescopic ends of the two electric telescopic rods 305 slide and penetrate the outer surfaces of the two mounting blocks 301, and the telescopic ends of the two electric telescopic rods 305 are respectively provided with first clamping blocks 306.

[0025] The clamping assembly 4 includes two connecting frames 401, the inner surfaces of the two connecting frames 401 are respectively threadedly connected to the outer surfaces of the two first threaded rods 303, the inner sides of the two connecting frames 401 are respectively matched with second clamping blocks 402, the outer surfaces of the two second clamping blocks 402 are respectively symmetrically fixedly connected with fixing rods 404, the outer surfaces of the multiple fixing rods 404 respectively slide through the outer surfaces of the two connecting frames 401, the inner surfaces of the two connecting frames 401 are respectively threadedly connected with the second threaded rods 403, and the second threaded rods 403 are matched with the second clamping blocks 402.

[0026] The two mounting blocks 301 are symmetrically arranged, wherein an outer surface of one side of one mounting block 301 is fixedly connected to the outer surface of the rotating block 1 near the bottom position, and an outer surface of one side of the other mounting block 301 is fixedly connected to the outer surfaces of the two fixed blocks 2 near the top position, and the other outer surfaces of the two mounting blocks 301 are respectively fixedly connected to connecting blocks 308, and the inner surfaces of the two connecting blocks 308 are respectively fixedly connected to threaded sleeves 309, and the two threaded sleeves 309 are matchedly arranged, and the rear surfaces of the two mounting blocks 301 are respectively fixedly connected to sliding rods 304 at positions away from the two first threaded rods 303, and the outer surfaces of the two sliding rods 304 are respectively slidably connected to the inner surfaces of the two connecting frames 401.

[0027] The effect achieved by the entire embodiment 1 is: when assisting the docking of the municipal drainage pipe, first use bolts to thread the two threaded sleeves 309 set in the two connecting blocks 308 to make the two mounting blocks 301 fit tightly, and then fit the inner sides of the two mounting blocks 301 and the inner sides of the two first clamping blocks 306 to the surface of the drainage pipe that can be fixedly supported, and insert the drainage pipe for docking into the inner sides of the two connecting frames 401.

[0028] The two electric telescopic rods 305 are started synchronously, so that the telescopic ends of the two electric telescopic rods 305 move toward each other, driving the two first clamping blocks 306 to clamp the surface of the drainage pipe that can be fixedly supported. The first clamping blocks 306 with larger cross-sections fully fit the surface of the drainage pipe, fixedly supporting the whole, and playing a fixing role.

[0029] At this time, the two connecting frames 401 are suspended on the outside of the docking pipes through two second threaded rods 403 and two sliding rods 304. The two handles set on the top and bottom of the two second threaded rods 403 are rotated in turn and rotated. The two second threaded rods 403 move toward the pipe surface respectively and push the two second clamping blocks 402. The multiple fixing rods 404 will slide within the two connecting frames 401 to clamp and fix the docking pipes.

[0030] Then, the two motors 302 are started synchronously, and the output ends of the two motors 302 respectively drive the two first threaded rods 303 to rotate in the two connecting frames 401. Under the action of the threaded rotation connection, the two connecting frames 401 drive the clamped butt-jointed pipes to move along the surfaces of the two sliding rods 304 toward the adjacent fixed pipe interfaces until the end faces of the two water pipes collide with each other, thereby playing an auxiliary butt-jointing role for the drainage pipes, making it convenient for personnel to use tools such as welding guns to weld the butt joints of the two pipes for fixed connection.

[0031] Then, the two second threaded rods 403 are rotated in the opposite direction to release the clamping of the two second clamping blocks 402 on one side of the docking pipe, and the bolt is rotated out of the two threaded sleeves 309 using a tool. After the two mounting blocks 301 are separated from one side close to the two connecting blocks 308, the two mounting blocks 301 are held and rotated in opposite directions respectively, and the rotating block 1 will rotate accordingly on the outer surface of the fixed shaft 5 connected between the two fixed blocks 2. The two mounting blocks 301 are rotated open with the fixed shaft 5 as the axis, and drive the separation of the clamping components, which plays a role in rapid disassembly, improves the use effect of the auxiliary docking device of the municipal drainage pipe, and solves the problem that the closed docking device in the background technology needs to slide out along one side of the closed pipe after the pipe docking and fixation is completed, and is difficult to remove quickly.
