Description

Technical Field

[0001] This utility model relates to the technical field of pipeline construction lifting devices, specifically a water supply and drainage pipeline construction lifting device. Background Technology

[0002] Water supply and drainage pipelines are the "vascular network" of urban infrastructure and building systems. Their core function is to achieve the orderly transportation of water resources and the efficient discharge, collection, and treatment of sewage and rainwater. They are crucial for ensuring human production and life, and maintaining public health and the ecological environment. The core of the water supply pipeline system is to transport water resources that meet water quality standards from water sources (such as reservoirs, rivers, and groundwater) to water treatment plants, where they are treated and then distributed to various water-using terminals such as residents, industries, and public facilities, achieving an orderly supply "from source to tap." Its function and role focus on "safe, stable, and efficient water supply."

[0003] Currently, the construction of water supply and drainage pipelines first involves excavating a suitable trench in the ground, then burying the pipeline inside. The pipeline is typically lifted into the trench using hoisting machinery, and then lowered back into the trench. During this subsequent hoisting, the pipeline is usually secured with lifting ropes to connect it to the hoisting equipment. While the lifting ropes serve their purpose of connection during pipeline lifting, slippage can occur, causing the pipeline to tilt or even fall, seriously threatening the safety of construction workers. Therefore, we have developed a water supply and drainage pipeline construction lifting device to solve these problems. Utility Model Content

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this water supply and drainage pipeline construction lifting device has the following advantages:

[0018] I. This water supply and drainage pipeline construction lifting device, through the cooperation of the rail, slide, and clamp, supports the slide through the rail, creating a gap between the slides, and the clamp tightly wraps around both ends of the pipeline to prevent the pipeline from moving, thus maintaining the stability of the pipeline.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5As shown, this utility model provides a technical solution: a lifting device for construction of water supply and drainage pipelines, including a support plate 1, a lifting lug 2 is provided above the support plate 1 and the lifting lug 2 is located at the center of the support plate 1, and a track 3 is fixedly connected below the support plate 1. Two sliding seats 4 are in contact with each other on the outer surface of the track 3 and the two sliding seats 4 are symmetrical. The track 3 supports and guides the movement of the sliding seats 4 and maintains the stability of the sliding seats 4.

[0029] Two grippers 5 are provided below the slide block 4, and the two grippers 5 are symmetrical. One gripper 5 is fixedly connected to the bottom of the slide block 4, and a pull rod 6 is connected to one side of the other gripper 5. The outer surface of the pull rod 6 is slidably connected to the inner wall of the slide block 4. The pipe is wrapped inside by the two grippers 5, thereby maintaining the stability of the pipe. The pull rod 6 is used to control the position of the gripper 5.

[0030] A guide rod 8 is fixedly connected to the inner wall of the slide block 4. The other end of the guide rod 8 is fixedly connected to one side of one of the grippers 5. The inner wall of the other gripper 5 is slidably connected to the outer surface of the guide rod 8. The guide rod 8 provides support force to the gripper 5, thereby improving the stability of the gripper 5.

[0031] A reinforcing frame 9 is fixedly connected to the top of the support plate 1, and a lifting lug 2 is fixedly installed above the reinforcing frame 9. The reinforcing frame 9 increases the load-bearing capacity of the support plate 1, and the lifting lug 2 is used to connect to the lifting machinery.

[0032] The inner thread of the slide 4 is connected to a locking bolt 10. One end of the locking bolt 10 inside the slide 4 contacts the outer surface of the track 3. The locking bolt 10 provides resistance to the slide 4, restricts the movement of the slide 4, and maintains the stability of the slide 4. After the locking bolt 10 is released from contact with the track 3, the positioning restriction on the slide 4 is released, and the slide 4 can be moved to adjust the distance between the two slides 4 to accommodate pipes of different lengths.

[0033] Anti-slip pads 11 are fixedly installed on the inner side of both grippers 5. The anti-slip pads 11 are made of rubber material. The anti-slip pads 11 increase the friction between the grippers 5 and the pipe, thereby improving the stability when clamping the pipe.

[0034] Handrails 12 are fixedly connected to both ends of the support plate 1, and a handle 13 is fixedly connected to the end of the pull rod 6 away from the claw. The handrails 12 facilitate the operation of the entire device by the staff, and the handle 13 facilitates the movement of the pull rod 6.

[0035] A positioning mechanism 7 is provided on the outside of the slide block 4 to maintain the stability of the pull rod 6. The positioning mechanism 7 includes a sliding sleeve 701, which is fixedly installed on one side of the slide block 4. A stop 702 is slidably connected to the inner wall of the sliding sleeve 701. Multiple stop grooves 703 are opened on the inner side of the pull rod 6, and the multiple stop grooves 703 are arranged at equal intervals. One end of the stop 702 contacts the inner wall of one of the stop grooves 703. The contact between the stop 702 and the stop groove 703 provides resistance to the pull rod 6, limiting the return of the pull rod 6 and the clamp 5. The other end of the stop 702 is rotatably connected to a slide rod 704. A spring 710 is sleeved on the outside of the slide rod 704. One end of the spring 710 is fixedly connected to one end of the stop 702, and the other end of the spring 710 is fixedly connected to the inner top wall of the sliding sleeve 701. The spring 710 provides an elastic pushing force to the stop 702, pushing the stop 702 to contact the stop groove 703 tightly. A pull ring 705 is fixedly connected to the top of the slide rod 704. A positioning rod 706 is fixedly connected to the inner side of the slide rod 704. A sleeve 707 is fixedly connected to the upper surface of the slide sleeve 701. The inner wall of the sleeve 707 is slidably connected to the outer surface of the slide rod 704. A slide rail 708 is provided on the inner side of the sleeve 707. The inner wall of the slide rail 708 is slidably connected to the outer surface of the positioning rod 706. A positioning groove 709 is provided on the inner side of the sleeve 707, and the positioning groove 709 is aligned with the outer surface of the positioning rod 706. The positioning rod 706 is adapted to the positioning rod 706. The pull ring 705 and the slide rod 704 are used to drive the pawl 702 to move. After the pawl 702 moves, it disengages from the pawl groove 703 and releases the positioning support of the pull rod 6. When the pawl 702 does not need to be reset, the positioning rod 706 is brought into contact with the positioning groove 709 by rotating the slide rod 704. The positioning groove 709 provides positioning support for the pawl 702 through the positioning rod 706, thus restricting the pawl 702 from resetting.

[0036] Working principle: In use, first move the slide block 4 to the position suitable for the pipeline. As the slide block 4 moves, the clamp 5 moves simultaneously. Then tighten the locking bolt 10 to restrict the movement of the slide block 4. Next, wrap the clamp 5 around the outside of the pipeline. Then, push the pull rod 6 and the clamp 5 to move through the pull ring 705, tightly clamping the pipeline inside the two clamps 5. At the same time, the stop 702 contacts the stop groove 703, restricting the movement of the pull rod 6 and the clamp 5 and maintaining the stability of the clamp 5. After the pipeline is hoisted into the trench, the pull ring 705 drives the stop 702 to disengage from the stop groove 703, releasing the restriction on the pull rod 6 and the clamp 5. Then, the handle 13 drives the clamp 5 to move, causing the clamp 5 to disengage from the pipeline, and then the next pipeline lifting and hoisting operation can be carried out.
