[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a track connection seat for an inspection vehicle. Figure 1 and Figure 2 The inspection vehicle track connection seat includes a fixed plate 1, a customized bolt group 2, a cross beam 3 and a bottom connecting piece 4. The fixed plate 1 is attached to the outer wall of the beam box. The fixed plate 1 is fixed to the ventilation hole of the beam box by the customized bolt group 2. The cross beam 3 is horizontally arranged and connected to the outer side of the fixed plate 1. The bottom connecting piece 4 is arranged at the bottom of the outer end of the cross beam 3. The bottom connecting piece 4 is used for detachable assembly with the inspection vehicle track.

[0031] In this embodiment, the customized bolt group 2 includes a screw rod 21, a limiting cap 22 and a locking nut 23. The screw rod 21 passes through the fixed plate 1, the limiting cap 22 is fixed to the inner end of the screw rod 21, and the locking nut 23 has multiple threads and is threadedly assembled on the outer end of the screw rod 21. In order to better adapt to the special structure of the ventilation hole on the beam box, the angle between the fixed plate 1 and the screw rod 21 is A, and the angle between the limiting cap 22 and the screw rod 21 is B. A and B are both between 70-90 degrees, and A is greater than B.

[0032] In order to prevent the locking nut 23 from slipping and loosening, the customized bolt group 2 also includes a gasket 24 , the screw rod 21 passes through the gasket 24 , and the gasket 24 is clamped between the locking nut 23 and the fixing plate 1 .

[0033] The customized bolt group 2 designed above has a simple structure and is more convenient to install and construct.

[0034] Specifically, in order to improve the overall structure of the inspection vehicle track connecting seat, the crossbeam 3 is an I-beam, and a reinforcement plate 5 is vertically connected between the upper surface of the crossbeam 3 and the outer side surface of the fixed plate 1, wherein there are two reinforcement plates 5, and the two reinforcement plates 5 are arranged in parallel and spaced apart, and the reinforcement plates 5 are a right triangle.

[0035] In this embodiment, the bottom connecting member 4 includes a vertical plate 41, a bottom plate 42, a stiffening plate 43 and a connecting bolt group 44. The vertical plate 41 is vertically connected to the middle of the beam 3, the bottom plate 42 is vertically connected to the bottom of the vertical plate 41, and the stiffening plate 43 is vertically connected to the lower surface of the beam 3, the middle side surface of the bottom plate 42, and the middle upper surface of the bottom plate 42. A plurality of strip holes are opened on the bottom plate 42, and the connecting bolt group 44 is vertically arranged and passes through the strip holes. There are two stiffening plates 43, and the two stiffening plates 43 are respectively located on both sides of the vertical plate 41. The stiffening plate 43 is in the shape of a right-angled trapezoid, and the connecting bolt group 44 is equally divided into two parts, and the two parts of the connecting bolt group 44 are respectively located on both sides of the stiffening plate 43.

[0036] The connecting bolt group 44 is a fully threaded bolt of M24x210-8.8, and each bolt is covered with 4 nuts, which can adjust the installation height of the inspection vehicle track within the range of ±22mm; the design of the horizontally arranged strip holes can adjust the size of the inspection vehicle track in the span direction within the range of ±16mm; and a long hole with a longitudinal length of 56mm is opened on the upper flange of the inspection vehicle track, which can adjust the size of the inspection vehicle track in the direction within the range of ±16mm. The size adjustment in these three directions can well adapt to the actual situation on site and ensure the installation quality of the inspection vehicle track. All bolts should be tightened once after all the inspection vehicle tracks are installed and adjusted properly and after appropriate running-in to release the residual stress.

[0037] The bottom connecting piece 4 of the above-mentioned design has a simple and firm structure, is more convenient to install and disassemble, is conducive to quickly installing and fixing the inspection vehicle track, and the inspection vehicle track is not easy to shake.
