Description

Technical Field

[0001] The utility model relates to the technical field of track bed contact rails, in particular to a pre-embedded nylon sleeve bracket for a cast-in-place integral track bed contact rail. Background Art

[0002] The trackbed contact rail, also known as the third rail, is a power supply method used in urban rail transit systems. It is usually located on one side of the track and provides power by contacting the collector shoe on the train, enabling the train to run. The contact rail system is an important subsystem of the subway traction power supply system, which directly affects the safe operation of the subway power supply system and even the entire subway system. During the trackbed laying process, the rails are first hoisted and fine-tuned. After the steel bars are tied, the embedded sleeves are fixed to the rails using tooling equipment, and the spiral steel bars outside the embedded sleeves are welded to the longitudinal and transverse steel bars of the trackbed. When the poured concrete reaches 75% strength, the bolts are unscrewed and the tooling equipment is removed.

[0003] At present, during the concrete pouring process, the sleeve may be displaced, skewed and other problems. The later installation of the contact rail bracket is difficult and requires manual support, which wastes unnecessary manpower and has low work efficiency. In order to solve the above technical problems, we have designed a pre-embedded nylon sleeve bracket for the cast-in-place integral roadbed contact rail. Utility Model Content

[0004] The purpose of the utility model is to provide a pre-embedded nylon sleeve bracket for the contact rail of a cast-in-place integral roadbed, which has the advantages of good positioning effect and strong stability, and solves the problems that the sleeve may shift or tilt during the concrete pouring process, and the problem that the later installation of the contact rail bracket is difficult and requires manual support.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cast-in-place integral track bed contact rail embedded nylon sleeve bracket, comprising a bracket body, a mounting plate 1 is fixedly welded to the front side of the left side of the bracket body, a mounting plate 2 is fixedly welded to the middle end of the right side of the bracket body, a line track is installed on the top of the bracket body, a clamping block is fixedly installed on the front side of the top of the bracket body and located at the front side of the line track, and a clamping plate is fixedly installed on the rear side of the top of the bracket body and located at the rear side of the line track.

[0006] Preferably, fixing bolts are installed through the tops of the first and second mounting plates, threads are provided on the bottoms of the surfaces of the fixing bolts, and rust-proof sleeves are provided on the tops of the surfaces of the fixing bolts.

[0007] Preferably, a connecting bolt is provided through the top of the clamping block, and a bottom of the connecting bolt is provided through the top of the clamping block and is threadedly connected to the top of the bracket body.

[0008] Preferably, a mounting bolt is provided through the rear side of the bottom of the bracket body and directly below the clamping plate, and the bottom of the mounting bolt is fixedly connected to a rotating handle.

[0009] Preferably, the top of the mounting bolt passes through the bracket body and the clamping plate in sequence and is threadedly sleeved with a mounting nut, and the front side of the clamping plate is in a tilted state.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The utility model limits the line track by the clamping block and the clamping plate, and uses the fixing bolts to cooperate with the mounting plate one and the mounting plate two to fix the bracket body to the ground, so that the line track can be installed stably to avoid shaking, improves the installation stability of the embedded sleeve, eliminates the need for manual fixing, saves physical strength, and improves work efficiency.

[0017] See also Figures 1-4 A cast-in-place integral track bed contact rail embedded nylon sleeve bracket, including a bracket body 1, a mounting plate 2 is fixedly welded to the front side of the left side of the bracket body 1, a mounting plate 2 is fixedly welded to the middle end of the right side of the bracket body 1, a line track 5 is installed on the top of the bracket body 1, a clamping block 8 is fixedly installed on the front side of the top of the bracket body 1 and located in front of the line track 5, and a clamping plate 10 is fixedly installed on the rear side of the top of the bracket body 1 and located in the rear side of the line track 5;

[0018] See also Figure 1, the tops of the mounting plates 1 2 and 2 4 are penetrated by fixing bolts 3, the bottom of the surface of the fixing bolts 3 is provided with threads, and the top of the surface of the fixing bolts 3 is provided with an anti-rust sleeve. By providing the anti-rust sleeve, the surface of the fixing bolts 3 can be protected, because its surface is exposed to the outside and is prone to rust. This operation can extend the service life of the fixing bolts 3;

[0019] See also Figure 3 The top of the clamping block 8 is penetrated by a connecting bolt 9, and the bottom of the connecting bolt 9 is penetrated by the top of the clamping block 8 and is threadedly connected to the top of the bracket body 1;

[0020] See also Figure 2 , a mounting bolt 7 is provided on the rear side of the bottom of the bracket body 1 and directly below the card plate 10. The bottom of the mounting bolt 7 is fixedly connected with a rotating handle 6. By setting the rotating handle 6, the card block 8 can be installed in advance. When it needs to be fixed, it can be directly clipped into the surface of the line track 5. Only the card plate 10 needs to be fixed, which saves installation time;

[0021] See also Figure 3 and Figure 4 The top of the mounting bolt 7 passes through the bracket body 1 and the clamping plate 10 in sequence and is threaded with a mounting nut 11. The front side of the clamping plate 10 is in a tilted state, which can make it easier for the clamping plate 10 to be clamped into the surface of the line track 5 to achieve stable clamping.

[0022] After the bracket 1 is fixed on the ground, the bracket 1 is fixed on the ground, and the bracket 1 is fixed on the ground, so that the bracket 1 is fixed on the ground.

[0023] To sum up: the pre-embedded nylon sleeve bracket for the cast-in-place integral track bed contact rail solves the problems of possible displacement and skew of the sleeve during the concrete pouring process, and the difficulty in installing the contact rail bracket in the later stage, which requires manual support, through the cooperation of the bracket body 1, mounting plate 1 2, mounting plate 2 4, line track 5, mounting bolts 7, clamping blocks 8 and clamping plates 10.
