Description

A tunnel laying cable lifting device

technical field

The utility model relates to a cable hoisting device for tunnel laying, which belongs to the innovative technology of the cable hoisting device for tunnel laying.

Background technique

The biggest feature of laying cables in tunnels is that they need to be moved to supports after the laying is completed. However, due to factors such as narrow space and efficiency in the tunnel, manual loading or lever blocks are generally used. For lower bracket heights (below 1.6m) or light weight cables, manual loading is used; for higher bracket heights (above 1.6m) or heavy cable weights, lever hoists are used for loading. Manual racking requires a large number of people, and the continuity and stability are low. Simple scaffolding needs to be erected, and cables and people will be injured if you are not careful; although hand hoist racking can solve the situation when manpower cannot be racked, it is time-consuming. Quite long and very inefficient.

Contents of the invention

The purpose of this utility model is to consider the above problems and provide a tunnel laying cable lifting device that can ensure high-efficiency loading, and at the same time ensure that cables and people will not be hurt, and greatly reduce potential safety hazards. The utility model is reasonable in design, convenient and practical.

The technical scheme of the utility model is: the tunnel laying cable lifting device of the utility model includes a pillar, a motor, a pull wire, and a fixed pulley, wherein the motor is installed at the lower part of the pillar, and the top of the pillar is a T-shaped structure. One side of the structure is bound with a pull wire, the other side of the T-shaped structure is hung with a fixed pulley, and a lifting cable is wound on the fixed pulley. One end of the lifting cable is connected to the output shaft of the motor, and the other end of the lifting cable is installed. There is a hook, and the guy wire can be connected with the lifting cable.

The utility model solves the difficulty that manpower cannot or is very laborious for laying cables in tunnels. It has high continuity and stability, ensures high-efficiency loading, and at the same time ensures that cables and people will not be hurt, greatly reducing safety hazards. The utility model is reasonable in design, convenient and practical, can greatly reduce the labor cost of construction personnel, and greatly shorten the construction period.

detailed description

The tunnel laying cable hoisting device of the present utility model includes a pillar 1, a motor 2, a pull wire 4, and a fixed pulley 5, wherein the motor 2 is installed at the lower part of the pillar 1, and the top of the pillar 1 is a T-shaped structure. One side of the T-shaped structure is bound with a stay wire 4, a fixed pulley 5 is hung on the other side of the T-shaped structure, and a lifting cable is wound on the fixed pulley 5. One end of the lifting cable is connected with the output shaft of the motor 2, and the other end of the lifting cable A hook is installed at one end, and the stay wire 4 can be connected with the lifting cable.

In this embodiment, the above-mentioned motor 2 is locked on the lower part of the pillar 1 through the adjusting bolt 3, and the installation position of the motor 2 can be adjusted up and down according to the site conditions, and is locked on the lower part of the pillar 1 with the adjusting bolt 3 after adjustment.

In this embodiment, the above-mentioned pillar 1 is a steel pipe with a length of about 3 meters.

In this embodiment, a cable support bracket 6 may also be provided below the above-mentioned pillar 1, and the cable support bracket 6 is placed under the cable after the cable lifting device lifts the cable to an appropriate height.

In this embodiment, a supporting rod 7 is installed on the top of the above-mentioned cable supporting bracket 6 , and a limiting device 8 is installed at the end of the supporting rod 7 .

In this embodiment, the above-mentioned cable support bracket 6 is a steel pipe.

When the tunnel laying cable hoisting device of the utility model is in use, the cable is tied with a sling and hung on the hook of the hoisting cable. When the height is slightly higher than the cable support bracket 6, place the cable support bracket 6 on the lower side of the cable, and place the limit device 8 on the cable support bracket 6, and then loosen the hook to place the cable on the cable support Finally, manually push the cable into the cable hoop.

The utility model can be used by multiple sets at the same time, and the shelf-loading efficiency will be improved. When multiple units are used together, they need to cooperate with each other to avoid cable damage due to incoordination, and at the same time, pay attention to the safety of temporary power use.

The economic benefit of the present utility model can be analyzed as follows:

Taking a 220kV power cable with a core cross-sectional area of 2500mm2 (the weight is about 40kg per meter) on a support about 1.6 meters high as an example, the situation of putting the cable on the shelf every 20 meters is as follows: How to put it on the shelves Number of workers (units) time (minutes) Time required for 500m cable (hours) Remark Human shelves 15 12 5 Need to build 1 meter simple scaffolding Prototype hoist 9 10 4 lifting device 7 8 3

It can be seen from the above table that the lifting device of the present invention requires fewer workers and less time than the former two, which greatly reduces the labor cost of construction personnel and greatly shortens the construction period.
