Hoisting device for hoisting indoor buried drainage pipe

Abstract

The utility model discloses a hoisting device for hoisting an indoor buried drain pipe. The hoisting device comprises a hoisting rope composed of a rubber sleeve, a steel wire rope and a rubber ring. During hoisting, the rubber sleeve of the hoisting rope makes contact with and extrudes the exterior of the drainage pipe, when extrusion force is transmitted to the rubber rings, the rubber rings enable the rubber sleeve to elastically deform and expand uniformly, the area of the rubber sleeve making contact with the drainage pipe is increased, and the rubber rings improve the elastic deformation uniformity of the hoisting rope so that the hoisting rope can make contact with the exterior of the drainage pipe in a larger area. The rubber sleeve is made of hard rubber, hard and rigid friction with the cast iron drainage pipe is avoided, damage is not prone to occurring, and the problem that damage is prone to occurring due to hoisting rigid contact friction after a steel wire rope is directly bound outside the drainage pipe is solved.

Description

Technical Field

[0001] The utility model relates to a hoisting device for hoisting indoor buried drainage pipes, belonging to the technical field of hoisting construction equipment. Background Art

[0002] When hoisting an indoor buried cast iron drainage pipe into a trench, in order to avoid bumping and damaging the cast iron drainage pipe during installation, the drainage pipe needs to be slowly hoisted and installed.

[0003] When hoisting the drainage pipe, the pipe needs to be tied tightly by a rope (see Chinese Patent Publication No. CN216687083U). Since the drainage pipe is made of cast iron and is heavy, a steel wire rope is usually directly tied to the outside of the drainage pipe for hoisting. However, the rigid contact and friction between the steel wire rope and the cast iron drainage pipe are likely to cause damage. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a hoisting device for hoisting indoor buried drainage pipes.

[0005] The utility model is realized through the following technical solutions.

[0006] A hoisting device for hoisting indoor buried drainage pipes provided by the utility model includes:

[0007] A hoisting rope composed of a rubber sleeve, a steel wire rope and a rubber ring.

[0008] The rubber sleeve that winds, binds and wraps the outside of the drainage pipe is made of hard rubber. The steel wire ropes are multiple and are spaced inside the rubber sleeve. A rubber ring is provided inside the inner layer of the rubber sleeve close to the outside of the drainage pipe. The rubber rings are multiple and are spaced. The elasticity of the rubber ring is less than the elasticity of the rubber sleeve made of hard rubber.

[0009] It also includes a hoist that hooks the hoisting rope.

[0010] Both ends of the steel wire rope are U-shaped and are hooked to the hook of the hoist.

[0011] It also includes a stress plate for installing the hoist.

[0012] It also includes a trench and a drainage pipe suspended in the trench space. The rubber sleeve of the hoisting rope winds, binds and wraps the outside of the drainage pipe.

[0013] The beneficial effects of the present utility model are as follows: When hoisting, the rubber sleeve of the hoisting rope contacts and presses the outside of the drain pipe. When the extrusion force is transmitted to the rubber ring, multiple rubber rings cause the rubber sleeve to elastically deform and expand uniformly, increasing the contact area with the drain pipe. The presence of multiple rubber rings improves the uniformity of the elastic deformation of the hoisting rope, enabling a larger area to contact the outside of the drain pipe. The rubber sleeve is made of hard rubber, avoiding hard and rigid friction with the cast iron drain pipe and not easily being damaged, solving the problem that rigid contact friction easily occurs and causes damage when a steel wire rope is directly tied to the outside of the drain pipe for hoisting.

[0018] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0019] As Figures 1 to 3 shown.

[0020] A hoisting device for hoisting an indoor buried drain pipe of the present application includes:

[0021] A stress plate 1 supported by a support frame or lifted by a crane during use, and a hoist 2 is installed on the stress plate 1 to facilitate the operator to control the hoisting height of the drain pipe 5 through the hoist 2.

[0022] It further includes a hoisting rope 3 hooked to the hoist 2, and the hoisting rope 3 is wound and tied around the outside of the drain pipe 5 and suspended in the space of the channel 4.

[0023] The hoisting rope 3 includes a rubber sleeve 31 made of hard rubber, and the rubber sleeve 31 is wound and tied around the outside of the drain pipe 5;

[0024] There are multiple steel wire ropes 32 spaced apart inside the rubber sleeve 31. The steel wire ropes 32 meet the load for hoisting the drain pipe 5. Both ends of the steel wire ropes 32 are U-shaped and penetrate through the rubber sleeve 31 to be hooked to the hook of the hoist 2, as Figure 3 shown;

[0025] Inside the inner layer of the rubber sleeve 31 on the outside of the drain pipe 5, there are rubber rings 33. The rubber rings 33 are distributed at intervals. The elasticity of the rubber rings 33 is less than that of the rubber sleeve 31 made of hard rubber. When the rubber sleeve 31 contacts and presses the outside of the drain pipe 5, when the extrusion force is transmitted to the rubber rings 33, multiple rubber rings 33 cause the rubber sleeve 31 to elastically deform and expand evenly, increasing the contact area with the drain pipe 5. The presence of multiple rubber rings 33 improves the uniformity of elastic deformation of the lifting rope 3 to make a larger area contact the outside of the drain pipe 5. The rubber sleeve 31 is made of hard rubber to avoid hard and rigid friction with the cast iron drain pipe 5 and is not easily damaged, solving the problem that rigid contact friction is likely to occur and cause damage when a steel wire rope is directly tied to the outside of the drain pipe for lifting.
