[0001] The utility model relates to the technical field of railways, in particular to an adaptive gauge device for a double-rail T-shaped measuring instrument. Background Technique

[0002] A railway is a transportation system that uses track technology to move trains for transportation purposes. Generally, two parallel tracks are set on the railway, and then the train travels along the two predetermined and parallel tracks. To ensure the safety of driving, it is necessary to regularly maintain the tracks.

[0003] The gauge between the two steel rails of the railway varies between 1435 - 1455 mm. Therefore, the measuring equipment pushed on the steel rails needs to be able to adapt to the change of the gauge. Otherwise, when passing through the curve section, it is extremely easy to derail. At the same time, because the direction of the thrust of each person is different when pushing, it may also cause the problem of the equipment derailing. Therefore, when developing the track-pushing measuring equipment, it must be able to meet the change of the gauge and ensure the stability of the equipment during the pushing process without derailing.

[0004] Therefore, how to provide an adaptive gauge device for a double-rail T-shaped measuring instrument is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] An object of the utility model is to provide an adaptive gauge device for a double-rail T-shaped measuring instrument. The utility model solves the problem that the distance between the two steel rails in the prior art changes, making it difficult for the measuring equipment pushed on the track to adapt to this distance change and prone to derailment.

[0006] According to an adaptive gauge device for a double-rail T-shaped measuring instrument of an embodiment of the utility model, it includes two steel rails and a push frame. A positioning walking wheel housing is arranged at the bottom of the push frame corresponding to the position of one steel rail, and a walking wheel group is arranged on the positioning walking wheel housing, and the walking wheel group rolls on one steel rail; on the other side of the push frame, a side walking wheel housing is arranged, an adaptive housing is movably arranged inside the side walking wheel housing, a main roller is arranged inside the adaptive housing, and the main roller rolls on the other steel rail. Two adjusting rods are also arranged on the adaptive housing, a positioning plate is fixed on the side walking wheel, the positioning plate is movably sleeved on the surfaces of the two adjusting rods, positioning blocks are arranged at the ends of the two adjusting rods far away from the adaptive housing, a spring member is movably sleeved on the surface of the adjusting rod, one end of the spring member is attached to the surface of the adaptive housing, and the other end of the spring member is attached to the side of the positioning plate far away from the adaptive housing; a push handle member is arranged on the push frame.

[0007] Inner side guide wheels are arranged on both the positioning walking wheel housing and the adaptive housing, and the inner side guide wheels slide on the inner side surfaces between the two steel rails.

[0008] The adaptive housing is provided with through holes, which are located between two adjusting rods. A guide rod is movably arranged inside the through holes, and both ends of the guide rod are fixed on the inner wall of the adaptive housing.

[0009] The walking wheel set includes two walking wheel members, which are arranged in parallel and roll on a steel rail.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By providing an adaptive housing, main rollers, adjusting rods, positioning plates and spring members, the main rollers and the walking wheel set walk on two steel rails to drive the trolley frame to walk. During the walking process, when the distance between the two steel rails decreases, the main rollers and the inner guide wheels will be squeezed and drive the adjusting rods to move on the fixing plates through the adaptive housing, so that the adaptive housing squeezes the spring members, causing the spring members to contract to adapt to this change. If the distance between the two steel rails becomes wider, the spring members will drive the main rollers and the inner guide wheels to fit the steel rail by squeezing the adaptive housing, thereby achieving the purpose of adaptive adjustment, achieving the effect that the main rollers and the inner guide wheels automatically adjust their positions to adapt to the change in the distance between the two steel rails, and solving the problem that it is difficult for the measuring equipment pushed on the track to adapt to this change in the distance between the two steel rails in the prior art and is prone to derailment.

[0019] Refer to Figure 1 and Figure 3 As shown in FIGS. and, it includes two rails 1 and a pushing frame 2. At the bottom of the pushing frame 2, a positioning running wheel housing 3 is arranged corresponding to the position of one rail 1. A running wheel set 4 is arranged on the positioning running wheel housing. The running wheel set 4 rolls on one rail 1. The running wheel set 4 includes two running wheel members 16. The two running wheel members 16 are arranged in parallel and roll on one rail 1. The design of the two running wheel members 16 enables the pushing frame 2 to move stably on the rail 1.

[0020] Refer to Figure 3 As shown in FIG., on the other side of the pushing frame 2, a side running wheel housing 5 is arranged. An adaptive housing 6 is movably arranged inside the side running wheel housing 5. A main roller 7 is arranged inside the adaptive housing 6. The main roller 7 rolls on the other rail 1. Inner guide wheels 13 are arranged on both the positioning running wheel housing and the adaptive housing 6. The inner guide wheels 13 slide on the inner side between the two rails 1. The inner guide wheels 13 can well abut against the inner side of the rail 1 to stabilize the positions of the main roller 7 and the running wheel set 4 on the rail 1, prevent deviation, and improve the movement stability of the main roller 7 and the running wheel set 4 on the rail 1.

[0021] Refer to Figure 2 and Figure 3, two adjusting rods 8 are further arranged on the adaptive housing 6. The two adjusting rods 8 are designed in parallel and are fixed on one side of the adaptive housing 6 close to the walking wheel set 4. A positioning plate 9 is fixed on the side walking wheel. The positioning plate 9 is movably sleeved on the surfaces of the two adjusting rods 8. In this way, the adaptive housing 6 moves on the positioning plate 9 through the two adjusting rods 8, and the adaptive housing 6 also moves inside the side walking wheel housing 5. A positioning block 10 is arranged at one end of the two adjusting rods 8 far away from the adaptive housing 6. A spring member 11 is movably sleeved on the surface of the adjusting rod 8. One end of the spring member 11 abuts against the surface of the adaptive housing 6, and the other end of the spring member 11 abuts against the side of the positioning plate 9 far away from the adaptive housing 6. The elastic force of the spring member 11 is used to squeeze the adaptive housing 6, so that it drives the main roller 7 and the inner roller to closely fit on the rail 1. A through hole 14 is formed in the adaptive housing 6. The through hole 14 is located between the two adjusting rods 8. A guide rod 15 is movably arranged inside the through hole 14. Both ends of the guide rod 15 are fixed on the inner wall of the adaptive housing 6. The guide rod 15 further improves the movement stability of the adaptive housing 6 and weakens the force-bearing condition of the two adjusting rods 8. During operation, when the distance between the two rails 1 becomes narrower, the rail 1 will squeeze the inner guide wheel 13 and the main guide wheel, and drive the adaptive housing 6 to move inward through the inward movement of the inner guide wheel 13 and the main guide wheel. The adaptive housing 6 moves inward and drives the adjusting rod 8 to move on the positioning plate 9. At this time, the spring member 11 contracts and provides a reaction force. Through this reaction force, the adaptive housing 6 drives the main roller 7 and the inner guide wheel 13 to stably fit on the rail 1. When the distance between the two rails 1 becomes wider, the spring member 11 will squeeze the adaptive housing 6, and drive the main roller 7 and the inner guide wheel 13 to closely fit on the rail 1 through the adaptive housing 6, thereby achieving the purpose of adaptively adjusting the distance between the two rails 1;

[0022] Reference Figure 1 and Figure 2 , a trolley handle member 12 is arranged on the trolley frame 2. The trolley handle member 12 includes a "C"-shaped rod 17 and a push rod 18. A sleeve 19 is arranged on the push rod 18. The sleeve 19 is sleeved on the surface of the "C"-shaped rod 17 through a locking bolt. In this way, the locking bolt can be loosened to change the position of the sleeve 19 on the "C"-shaped rod 17, and then change the position of the push rod 18, so as to change the pushing position. In this way, the position of the push rod 18 can be changed according to the actual situation, improving its practicability. The "C"-shaped rod 17 is fixed on the trolley frame 2.
