Universal rolling wheel device for pipeline support

Abstract

The invention relates to a pipeline sliding supporting piece, in particular to a universal rolling wheel device for a pipeline support. The universal rolling wheel device comprises a rolling device. The rolling device comprises a rolling wheel frame. A first rolling wheel and a second rolling wheel are installed on the rolling wheel frame, wherein the first rolling wheel is used for transverse sliding of the pipeline support, and the second rolling wheel is used for longitudinal sliding of the pipeline support. According to the universal rolling wheel device, transverse and longitudinal displacement of the pipeline support is achieved, the bearing capacity is good, and the friction force is small; the problems that a one-way rolling wheel device can only conduct one-way displacement and the stress of a universal ball structure is excessively large are solved.

Description

technical field [0001] The invention relates to a pipeline sliding support, in particular to a universal roller device for a pipeline support. Background technique [0002] The roller device is used between the pipe support and the rooting beam to reduce friction. After the friction of the support is reduced, the internal stress of the pipeline during thermal expansion can be reduced, the thrust of the support on the steel beam can be reduced, and the safety of the pipeline system can be increased. [0003] There are mainly three structural types of roller devices in the existing market: 1. Antifriction materials such as polytetrafluoroethylene are set between the pipe support and the steel beam to reduce friction. The advantage of this structure is that it is compact in structure and relatively small in vertical size. Small, the disadvantage is that it is not easy to fix the PTFE plate and the steel plate.

Problems solved by technology

[0003] There are mainly three structural types of roller devices in the existing market: 1. Antifriction materials such as polytetrafluoroethylene are set between the pipe support and the steel beam to reduce friction. The advantage of this structure is that it is compact in structure and relatively small in vertical size. Small, the disadvantage is that it is not easy to fix the PTFE plate and the steel plate. Using countersunk screws and bonding, the effect is not satisfactory. Once the environment used on site is too dusty, the actual friction will be seriously affected

In the case of the best effect, the friction coefficient can be reduced to 0.1; 2. A one-way roller device is installed between the pipe support and the steel beam. This structure can reduce the friction coefficient to 0.02~0.04, but it can only allow the pipe support The base plate is displaced axially along the pipe 3. Universal balls are installed between the pipe support and the steel beam. The advantage of this structure is that the friction coefficient can be reduced to 0.02~0.04, and the vertical dimension is also small. The disadvantage is that balls are used. The contact stress is too large, and there are special requirements for the material hardness of the upper and lower contact surfaces, which is not conducive to the bearing capacity of the support
