Description
Technical Field
The utility model belongs to the field of subway traction power supply systems, and particularly relates to an adjustable double-groove base for a rigid suspension contact network in a tunnel.
Background
With the rapid development of urban rail transit construction in China, the form of a rigid contact net suspension system is widely applied to underground sections. At present, shield tunnels are generally adopted in subway tunnels, tunnel segments need to be spliced through bolts, horseshoe-shaped holes for connecting the bolts are formed in the upper portions of the tunnel segments, connecting seams exist among the tunnel segments, and therefore anchor bolt holes cannot be formed in rear portions of the tunnel segments, a suspension device cannot be installed within a specified construction error range, and the construction method is mainly shown in the joint portion of an anchor section of a rigid suspension system. Meanwhile, the problem that holes cannot be formed in the positions of the embedded steel bars in the mine construction is solved.
The rigid suspension system anchor section joint is a key device of a rigid contact net system, requires accurate installation position, meets the displacement caused by the temperature change of the busbar, and has unchanged guide height. Due to the particularity of the tunnel structure, part of the sections can not meet the construction requirements and later-stage adjustment through the rear chemical anchor bolts.
Disclosure of Invention
Aiming at the technical problems in the prior art, the utility model provides an adjustable double-groove base for a rigid suspension contact net in a tunnel, wherein a base connecting plate and a groove-shaped slideway are designed and are connected with a rigid suspension device through a T-shaped bolt, and the groove-shaped slideway can meet the adjustment of the rigid suspension device along the direction of a line and meet the installation requirement in the tunnel of the line.
The technical scheme adopted by the utility model is as follows: the utility model provides an adjustable double flute base for rigid suspension contact net in tunnel, includes that the base links board, flute profile slide and T type connecting bolt, two are parallel to each other the flute profile slide all is fixed in on a plurality of bases link board, set up the through-hole on the base links the board, the flute profile slide is with a plurality of T type connecting bolt connects.
Further, the through hole is a long hole.
Furthermore, the grooved slide way is in sliding connection with the T-shaped connecting bolts, and bolt caps of the T-shaped connecting bolts are located in the grooved slide way.
Furthermore, the grooved slide way is fixed on the lower end face of the base connecting plate, and the T-shaped connecting bolt is hung on the grooved slide way.
Compared with the prior art, the utility model has the beneficial effects that:
1. the utility model can meet the installation of rigid suspension anchor section joints and common suspension positions, realizes the equal height of the installation positions of the suspension devices at the joints and has the function of adjustment along the line direction.
2. The long hole is formed in the base connecting plate, so that the mounting position of the rear anchor bolt can be kept away from a tunnel structure gap and other mounting hole positions, and the problem that the suspension device cannot be mounted due to the tunnel structure problem is solved.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The embodiment of the utility model provides an adjustable double-groove base for a rigid suspension contact net in a tunnel, which comprises a base connecting plate 1, a groove-shaped slideway 2 and a T-shaped connecting bolt 3 as shown in figures 1-2. The two parallel groove-shaped slideways 2 are fixed on the lower end surface of the base connecting plate 1. The base connecting plate 1 and the groove-shaped slideway 2 are both steel structural members and are welded and fixed, so that the mechanical performance requirement is met. Each base connecting plate 1 is provided with two long holes 4, the long holes 4 are positioned on the outer sides of the groove-shaped slideways 2, and the long holes 4 are used for fixing the base connecting plates 1 and the tunnel wall. The bolt cap of the T-shaped connecting bolt 3 is positioned in the groove-shaped slideway 2. The slotted slideway 2 is used for hanging the T-shaped connecting bolt 3.
As shown in fig. 3-4, the present embodiment is fixed to the tunnel wall by means of elongated holes 4 and anchor bolts 5, and the rigid suspension means 6 of the busbar are fixed by means of T-shaped connecting bolts 3. The rigid suspension device 6 can be selected from a cantilever suspension or a vertical suspension according to requirements. The rigid suspension means 6 effect adjustment of the span between suspension points by movement within the trough runner 2.
The present invention has been described in detail with reference to the embodiments, but the description is only illustrative of the present invention and should not be construed as limiting the scope of the present invention. The scope of the utility model is defined by the claims. The technical solutions of the present invention or those skilled in the art, based on the teaching of the technical solutions of the present invention, should be considered to be within the scope of the present invention, and all equivalent changes and modifications made within the scope of the present invention or equivalent technical solutions designed to achieve the above technical effects are also within the scope of the present invention.
