Description

Wire Rope Support Device

technical field

The utility model relates to a tower crane, in particular to a wire rope supporting device.

Background technique

The existing tower cranes are aimed at the use of steel wire ropes. Due to the lack of wire rope anti-wear and rope support devices, although theoretically the steel wire rope will not directly contact the steel structure of the tower crane under stress and tension, there will be a long time in the actual use process. , Long-distance direct contact with the steel structure of the tower crane, so the steel wire rope is easy to wear during use, so the following technical disadvantages will appear:

1. The wire rope wears fast, and the cost of use and maintenance is high. Due to the lack of wire rope anti-wear devices, the wire rope wears fast, reducing its service life, increasing the frequency of regular inspection and maintenance of the wire rope and replacing the wire rope, resulting in increased use and maintenance costs for users.

2. High potential safety hazard. Because the steel wire rope wears fast, and the wear may be uneven and uncontrollable, it will cause the steel wire rope to be used with a problem, thereby posing a safety hazard.

Contents of the invention

Aiming at the above-mentioned problems in the prior art, the utility model provides a wire rope supporting device, which reduces the wear of the wire rope, prolongs the service life of the wire rope, improves the safety of crane lifting, and is easy and quick to install.

In order to achieve the above object, the technical solution adopted by the utility model is: a steel wire rope rope supporting device, including a rope supporting device and a mounting support; the rope supporting device includes a bolt shaft, a washer, a roller shaft, a bearing and a bolt group; The two ends of the roller shaft are installed on the bearing through the bolt shaft, the bearing is installed on the installation support, and the installation support is fixed on the steel structure of the tower crane; The seat rotates.

As a further improvement of the utility model, the roller shaft is a nylon roller. Compared with the rigid material in contact with the steel wire rope, the use of nylon rollers in contact with the steel wire rope can further reduce the wear resistance of the steel wire rope.

As a further improvement of the utility model, according to the normal use state of the steel wire rope (tensioned or unstressed) and the layout of the rope, multiple rope support devices are set at the opposite parts where the steel wire passes and pass through the installation support. It is fixed on the steel structure of the tower crane to prevent the steel wire rope from contacting the steel structure.

As a further improvement of the utility model, a washer is installed between the bolt shaft and the mounting seat. Protect the pressure of connecting parts, reduce scratches and improve service life.

As a further improvement of the utility model, the material of the mounting support is angle steel or plate.

As a further improvement of the utility model, the installation support is connected with the steel structure of the tower crane through a bolt group. It can also be connected by welding, but the bolt group is more convenient for disassembly and use.

The utility model steel wire rope supporting rope device, the roller shaft can be rotated on the mounting support, so that the steel wire rope is in contact with it instead of directly contacting the steel structure of the tower crane itself, the contact time between the steel wire rope and the roller shaft is short, the contact area is small, and the contact area is greatly reduced. wear of the wire rope. Therefore, it has the following advantages:

1. Extend the service life of the wire rope. It avoids the state of direct wear between the steel wire rope and the steel structure, effectively ensuring the service life of the steel wire rope.

2. Easy to install and disassemble. When installing and disassembling, the whole rope support device can be installed or disassembled together, and the operation is convenient and simple.

3. The structure is novel and reliable. The bolt shaft not only plays the role of fixing the nylon roller, but also plays the role of the mandrel of the roller shaft. And the roller shaft is made of nylon material, which can realize free rotation on the mounting support, greatly reducing the wear of the wire rope.

detailed description

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model steel wire rope support device includes a support device 2 and a mounting support 3; the support device 2 includes a bolt shaft 4, a washer 5, a roller shaft 6, a bearing 7 and a bolt group 8; The two ends of the roller shaft 6 are installed on the bearing 7 through the bolt shaft 4, the bearing 7 is installed on the mounting support 3, and the mounting support 3 is fixed on the steel structure 1 of the tower crane; the steel wire rope passes through the roller shaft 6, and the roller shaft 6 Rotate on the mounting support 3 with the bolt shaft 4 as the axis.

On the basis of the above structure, the roller shaft 6 of the utility model adopts a nylon roller. Compared with the contact between the rigid material and the steel wire rope, the use of the nylon roller to contact the steel wire rope can further reduce the wear resistance of the steel wire rope. According to the normal use state of the steel wire rope (stressed tension or unstressed relaxation) and the layout of the rope system, the utility model sets a plurality of rope support devices 2 at the relative parts where the steel wire rope passes and passes through the installation. The support 3 is fixed on the steel structure 1 of the tower crane to prevent the steel wire rope from contacting the steel structure 1 of the tower crane. The utility model is provided with a washer 5 between the bolt shaft 4 and the mounting seat 3 . Protect the pressure of connecting parts, reduce scratches and improve service life. Mounting support 3 material of the present utility model adopts angle steel or sheet material to obtain material conveniently.

The lifting performance and the design of the rope system are used to install several rope support devices in various parts. The rope support device 2 uses angle steel or plate as the installation support, and the roller shaft 6, bearing 7, bolt shaft 4 and The washer 5 is installed on the support 3, and fixed with bolts or welded on the steel structure 1 of the tower crane; the nylon roller can realize free rotation, so as to avoid direct contact between the steel wire rope and the steel structure of the tower crane, thereby reducing and slowing down the wear of the steel wire rope, reducing Tower crane maintenance costs.

Certainly, the above-mentioned embodiments are only preferred solutions of the present invention, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs, so as to obtain different implementation modes. Since there are many ways of possible realization, it is not necessary to give examples one by one here.
