Description

Pull buffer

technical field

The utility model relates to a tool used for substation installation and line erection, in particular to a tension buffer.

Background technique

Substation installation companies have more chances to use pulleys to lift equipment during new construction, reconstruction, expansion of substations, equipment installation and commissioning, equipment maintenance, and some line erection projects. However, during the hoisting process, the lifting points can only be selected on steel On the beam, there are often loose strands and broken strands in the wire rope sleeves using pulleys. The loose strands and broken strands of the wire rope sleeves are mainly caused by excessive friction between the steel wires and the steel frame. The pulling force caused great pressure between the wire rope sleeve and the steel frame, resulting in an increase in the friction between the steel frame and the steel wire, and repeated friction caused some steel wires to be worn off, resulting in loose or broken strands of the wire rope sleeve .

In order to improve the construction quality, reduce the loose strands and broken strands of steel wire rope sleeves during the construction process, and improve the safety of power transformation and line use pulley hoisting equipment, a method to solve this problem is urgently needed.

Contents of the invention

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a tension buffer, by alleviating the friction between the steel wire rope sleeve and the angle steel of the steel frame, so as to avoid personnel accidents caused by loose strands or breakage of the steel wire rope sleeve during hoisting. Injury and equipment damage issues.

In order to achieve the above object, the utility model adopts the following technical solutions:

The tension buffer is mainly composed of an inner clamping block and an outer clamping block respectively placed on both sides of the angle steel, and the wire rope sleeve is wound and fixed along the outer circumference of the inner and outer clamping blocks.

The internal shape of the inner clamping block and the outer clamping block is made according to the shape of angle steel, and the outer clamping block is arc-shaped. The inner clamping block and the outer clamping block are also embedded with magnets to attract the inner and outer clamping blocks together.

The wire rope sleeve is kept out of contact with the angle steel all the time.

The longitudinal dimension of the angle steel is smaller than the corresponding dimensions of the inner clamping block and the outer clamping block, and the longitudinal dimension of the angle steel is the dimension perpendicular to the extending direction of the angle steel.

The inner clamping block and the outer clamping block are connected together by small copper wires.

The inner clamping block and the outer clamping block are made of A/B type epoxy resin.

The utility model is composed of an inner clamping block and an outer clamping block which are respectively placed on both sides of the angle steel. Fixed, increasing the stress area of the wire rope, reducing the pressure on the wire rope sleeve, avoiding the direct contact between the wire rope sleeve and the edge of the angle steel, reducing the cutting damage of the angle steel edge to the wire rope sleeve, and overcoming the safety difficulties of using pulleys to lift equipment. It lays a solid foundation for the safety and reliability of hoisting equipment using pulleys during the construction process, and avoids personal injury and equipment damage caused by the sudden loose strands or breakage of the wire rope sleeve during the hoisting process.

Detailed ways

Below in conjunction with accompanying drawing, the utility model content is elaborated:

As shown in Figure 1-2, the tension buffer is composed of the inner clamping block 1 and the outer clamping block 2 respectively placed on both sides of the angle steel. The wire rope sleeve 6 is wound and fixed along the outer circumference of the inner and outer clamping blocks. The shape of the inner side of the block 2 is made according to the shape of the angle steel, and the outer side is arc-shaped. The inner clamping block 1 and the outer clamping block 1 are also embedded with a magnet 4 that attracts the inner and outer clamping blocks together. The inner clamping block 1 and the outer clamping block 1 The clamping blocks 2 are connected together by small copper wires 3 .

As shown in Figure 3, when in use, the inner clamping block 1 and the outer clamping block 2 are respectively placed on both sides of the tower material angle steel 5, and the inner clamping block 1 and the outer clamping block 2 are fixed on the tower material by the magnetic force of the magnet. Wrap the wire rope sheath 6 on the tension buffer along the outer circumference of the inner and outer clamping blocks, increase the stress area of the wire rope, reduce the pressure on the wire rope sheath, avoid direct friction between the wire rope sheath and the angle steel, delay the life of the wire rope sheath, reduce Due to the breakage of the steel wire rope cover causing personal injury and equipment damage, it is suitable for occasions where pulleys are used to hoist equipment in the process of substation and line construction, and it avoids the phenomenon of loose strands and broken strands of the steel wire rope cover during the hoisting process using pulleys, causing personal injury. , Improve the safety of construction and effectively ensure the quality of construction.

There are magnets 4 embedded in the inner clamping block and the outer clamping block. During use, the force on the surface will not change its position after being pulled, so as to avoid falling off; the inner and outer clamping blocks are connected by small copper wires, which is generous Beautiful, easy to carry during construction and avoid loss.

The tension buffer is placed on both sides of the angle steel 5 to ensure that the wire rope cover 6 does not touch the angle steel 5 all the time. The longitudinal dimension of the angle steel 5 is smaller than the corresponding dimensions of the inner clamping block 1 and the outer clamping block 2. The longitudinal dimension of the angle steel 5 is The dimension perpendicular to the direction of extension of the angle steel 5 prevents friction between the steel wire rope sheath 6 and the angle steel 5 in direct contact, which may cause damage to the steel wire rope sheath.

The inner clamping block 1 and the outer clamping block 2 are made of A/B type epoxy resin to prevent the buffer from being deformed by a large tensile force during use; its inner shape is made according to the shape of the steel frame and the angle iron of the iron tower, The process of use is convenient, and it is closely connected with the lifting point in the process of hoisting, so that the construction is standardized and normalized.
