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 connecting 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 cone surface 9 and the cone hole 10, and it is temporarily not tightened.

[0029] The bracket 2 and the support 1 are pre-connected with bolts 8 and do not tighten them temporarily.

[0030] The support 1 is installed on the civil engineering datum surface 13 by bolts 7, the threaded connection 7 is tightened, and the support 1 is positioned and tightened.

[0031] The threaded connection 10 of the insulator 9 on the support and the threaded connection 8 between the support 2 and the support 1 are sequentially tightened to complete the tightening and positioning of the support system.

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 the installation and fixation of insulators of magnetic levitation power supply rails, and is mainly used for the installation and fixation of insulators of power supply rails of magnetic levitation trains. Background technique [0002] The power supply rail mounting brackets described in Patent Literature ZL200620064035.2 and Patent Literature 200320101485.0 are used as insulators for installing and fixing power supply rails, and are used on all lines except for turnouts. The above-mentioned brackets are all simple single-arm structures, one end is connected to the power supply rail (or power supply rail insulator), and one end is fixed to the installation datum. [0003] In the prior art, due to the large size deviation in civil construction, the position of the embedded part of the installation datum has a large deviation. The disadvantages of the above bracket system are: the adjustable range of the bracket i...
