Description

Technical Field

[0001] The utility model relates to the technical field of railway transportation, in particular to a special wheel box for railway transportation track transportation vehicles. Background Art

[0002] When transporting rail transit vehicles by rail, the usual practice is to weld two parallel rails on the railway transport flat car, then place the wheels of the rail transit vehicle on the rails, and then use wheel stoppers and wire ropes to reinforce the rail transit vehicle. This method has the following disadvantages: 1. Rails are controlled commodities, and their purchase requires special approval, and inventory is not allowed, and the procurement cycle is long. 2. Rails must be made of iron plates, which cannot be welded and fixed on wooden plates. 3. Rail welding requires an on-site fire permit, which increases time costs. 4. Rail welding technology has high requirements, and the rails that are removed after welding cannot be reused. 5. The labor cost of welders is high. 6. The welding method has a large fixing area, which causes great wear on the flat car and reduces the service life. In order to better solve the above problems, we propose a special wheel box for rail transportation rail transit vehicles. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1 , Figure 2A special wheel box for railway transportation rail transit vehicles includes a base 1 and a support seat 3. Two bases 1 are provided. A distance adjustment mechanism is installed between the two bases 1. The distance adjustment mechanism is used to adjust the distance between the two bases 1. By adjusting the distance between the two bases 1, the distance between the two wheels of the rail transit vehicle can be better matched. A first boss 2 is fixed to the side of the base 1. The first boss 2 is provided with equidistantly arranged bolt holes 11. The bolt holes 11 are sleeved with first bolts 12. The first boss 2 is fixed to the transport flat car by the first bolts 12. The first boss 2 is fixed to the transport flat car by the first bolts 12. No welding is required, and disassembly and assembly are convenient. The base 1 is provided with equidistantly arranged bolt holes 11. A screw hole 13 is arranged, an arc-shaped wheel supporting groove is opened on the top of the support seat 3, and an arc-shaped anti-skid pad 15 is fixed in the wheel supporting groove. The anti-skid pad 15 improves the stability of the rail transit vehicle wheel placed in the wheel supporting groove and reduces the movement. A second boss 4 is fixed at both ends of the support seat 3, and a second bolt hole is opened on the second boss 4. A second bolt 14 is sleeved in the second bolt hole, and the second bolt 14 is sleeved in the screw hole 13 through a thread. The support seat 3 and the base 1 are detachably connected through the second bolt 14 and the screw hole 13, which is convenient for replacing the support seat 3 according to the diameter of the rail transit vehicle wheel, so that the wheel supporting groove on the support seat 3 better matches the wheel of the rail transit vehicle.

[0019] Reference Figure 1 The distance adjustment mechanism includes an internal threaded sleeve 7 and a screw rod 8. The internal threaded sleeve 7 is fixed on one of the bases 1, and the screw rod 8 is rotatably sleeved on the other base 1. The screw rod 8 is sleeved in the internal threaded sleeve 7 through a thread. A sliding tube 5 is fixed on one of the bases 1, and a sliding rod 6 is fixed on the other base 1. The sliding rod 6 is slidably sleeved in the sliding tube 5. A hand wheel 9 is fixed at one end of the screw rod 8. The hand wheel 9 drives the screw rod 8 to rotate. The screw rod 8 can drive the internal threaded sleeve 7 to translate through the threaded transmission between the screw rod 8 and the internal threaded sleeve 7, thereby adjusting the distance between the two bases 1.

[0020] Working principle: The arc-shaped wheel support groove is used to support the wheels of rail transit vehicles.
