Description

Technical Field

[0001] The invention relates to a sliding bracket, in particular to a sliding bracket with adjustable installation height and small friction force. Background Art

[0002] At present, the sliding brackets widely used in the domestic power and petrochemical industries have the following disadvantages: 1) Before the sliding bracket is installed, the pipeline and the pre-embedded iron pad of the base have been installed and fixed, that is, the vertical distance between the two is a fixed value. When the height of the sliding bracket pipe clamp is greater than the space gap, the installation usually increases the space gap by lifting the pipeline, which is not conducive to the safe operation of the pipeline; when the height of the sliding bracket pipe clamp is less than the space gap, the bracket cannot be installed in place at one time, which brings great difficulties to the installation. 2) The sliding bracket pipe clamp and the embedded pad are in surface contact, and sliding friction occurs when sliding against each other, which is easy to generate large friction. Especially when arranged outdoors, the friction between the pipe clamp and the pad is further increased due to rust or uneven sliding surface, resulting in abnormal thermal displacement of the pipeline and increased pipeline stress. Summary of the invention

[0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a sliding bracket with adjustable installation height and small friction. The installation height of the bracket is adjustable and the friction is small.

[0004] To achieve the above-mentioned purpose, the sliding bracket with adjustable installation height and low friction force described in the present invention includes a pipe clamp; the pipe clamp is fixed on the pipeline, and support components are arranged at the positions of the four corners of the pipe clamp, wherein the support components include an adjustable shaft assembly, a thrust bearing and a universal wheel assembly;

[0005] The adjustable shaft assembly includes a different diameter shaft, a base and a vertical shaft; the universal wheel assembly includes a U-shaped bracket, a first bearing shaft, a first roller, a U-shaped bracket, a second roller, a second bearing shaft, a third roller and a fourth roller;

[0006] The top of the base is fixed on the pipe clamp, the upper end of the different-diameter shaft is inserted into the base and connected to the base through a thread, the thrust bearing and the U-shaped bracket are installed on the vertical shaft from top to bottom, the upper end of the vertical shaft is connected to the different-diameter shaft, and the lower end of the vertical shaft is sleeved with a nut;

[0007] The opening direction of the U-shaped bracket faces downward, the first load-bearing shaft passes through the first roller, the side of one end of the U-shaped bracket and the second roller to connect the first roller and the second roller to the U-shaped bracket, and the second load-bearing shaft passes through the third roller, the side of the other end of the U-shaped bracket and the fourth roller to connect the third roller and the fourth roller to the U-shaped bracket.

[0008] The countersunk screws are inserted into the pin holes on the sides of the base.

[0009] A first washer is arranged between the nut and the U-shaped bracket, wherein the first washer is sleeved on the vertical shaft, and a fixing pin passes through the nut and the vertical shaft to connect the vertical shaft with the nut;

[0010] The thrust bearing is composed of a shaft washer, a retainer, a steel ball and a seat washer which are sequentially mounted on the vertical shaft from top to bottom, wherein the end face of the shaft washer is connected to the bottom of the different diameter rotating shaft, and the seat washer is connected to the top of the U-shaped bracket.

[0011] The pipe clamp is fixed to the pipe by bolts.

[0012] One side of the U-shaped bracket is the first vertical plate, and the other side of the U-shaped bracket is the second vertical plate, wherein the first load-bearing shaft passes through the first roller, the first vertical plate and the second roller to connect the first roller and the second roller to the U-shaped bracket, and the second load-bearing shaft passes through the third roller, the second vertical plate and the fourth roller to connect the third roller and the fourth roller to the U-shaped bracket.

[0013] The present invention has the following beneficial effects:

[0014] During specific operation, the sliding bracket with adjustable installation height and low friction force described in the present invention has the upper end of the different-diameter rotating shaft inserted into the base and connected to the base by a thread. During installation, the different-diameter rotating shaft is rotated so that the height of the sliding bracket meets the distance requirement between the pipeline and the embedded component pad, thereby achieving adjustable installation height. After installation, the vertical downward pipeline load is transmitted to the base through the pipe clamp, and the thrust bearing transmits the load on the base to the universal wheel assembly. The load on the universal wheel assembly is borne by the embedded component pad below it. When the pipeline is displaced in the horizontal direction, the thrust bearing rotates, and the universal wheel assembly automatically rotates along the vertical axis and rolls along the displacement direction of the pipeline. Under the same load condition, the friction force of the rolling bearing is small, and the friction force of the present invention is smaller than that of the traditional sliding bracket.
