Problems solved by technology

The disadvantages of the above-mentioned support system are: the adjustable range of advance and retreat and deflection of the support itself in all directions is extremely small, and the adjustment accuracy and reliability are insufficient. Additional parts (such as gaskets, wedge irons, etc.) can achieve more accurate installation positioning
Due to the limited space at the installation position of the bracket, the bracket system using the prior art uses many additional parts, the connection, installation and construction are troublesome, the lasting stability is poor, and the final effect is difficult to guarantee

Embodiment Construction

[0027] Such as figure 1 , the support system is composed of a support 1 and a support 2, the support 1 clamps the support 2 to the connection surface 3, and is fastened by a pair of bolts 8.

[0028] Such as Figure 4 , the insulator 9 installed on the bracket is pre-positioned in space, and then the bracket 2 and the lower attachment of the insulator 11 are pre-connected through the installation of the conical surface 9 and the cylindrical hole 10, and are not fastened temporarily.

[0029] Pre-connect the bracket 2 and the support 1 through the bolt 8, do not fasten it temporarily.

[0030] The support 1 is installed on the civil engineering reference plane 13 through the bolt 7, and the threaded connection 7 is tightened to position and fasten the support 1.

[0031] The threaded connection 12 of the insulator 11 on the support and the threaded connection 8 between the support 2 and the support 1 are tightened successively to complete the fastening and positioning of the ...

Abstract

The invention discloses a bracket system used for mounting and fixing a conductor-rail insulator. The system is of a two-section structure formed by two section bars having mutually vertical penetrating directions, wherein a bracket 2 is held in a support base 1, and the bracket is fastened and connected with a holding side 3 through a bolt 8. By using the insulator mounting bracket provided by the invention, the space adjustment in wide range can be realized on the basis of construction error in a smaller space, the positioning and locking are precise, and the positioning is convenient, quick, stable and reliable.

Description

technical field [0001] The invention relates to a bracket system for installing and fixing insulators of power supply rails, which is mainly used for installing and fixing insulators of power supply rails of maglev trains. Background technique [0002] The power supply rail installation bracket described in patent document ZL200620064035.2 and patent document ZL200320101485.0 is used for installing and fixing power supply rail insulators on all lines except for turnouts. The above brackets are simple single-arm structures, one end is connected to the power supply rail (or power supply rail insulator), and the other end is fixed on the installation datum. [0003] In the prior art, due to large dimensional deviations in civil construction, large deviations occur in the positions of embedded parts on the installation basis. The disadvantages of the above-mentioned support system are: the adjustable range of advance and retreat and deflection of the support itself in all direc...
