Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. It is only noted that the utility model is intended to be limited to the specific forms set forth herein, including any reference to the drawings, as well as any other specific forms of embodiments of the utility model.
Referring to fig. 1 to 4, the utility model provides a high temperature resistant oilless bearing kettle vehicle, which comprises a frame 1 and a wheel component 2;
the frame 1 comprises a support table 11 and at least four mounting seats 12, the mounting seats 12 comprise two mounting plates 121 which are oppositely arranged, and mounting holes 122 for mounting the wheel parts 2 are formed in the mounting plates 121;
the wheel component 2 comprises a wheel shaft 21, a dry bearing 22 arranged on the wheel shaft 21, a wheel 23 sleeved on the dry bearing 22 and a limiting sleeve 24 for limiting the wheel 23, wherein a track groove 231 is formed in the wheel 23;
the dry bearing 22 is tightly fitted to the wheel 23, and the dry bearing 22 is in clearance fit with the wheel shaft 21.
Specifically, the support platform 11 is used for supporting a pipe pile, and the mounting seat 12 is used for mounting the wheel component 2. The mounting seat 12 comprises two mounting plates 121, and the mounting plates 121 are arranged in parallel with the running direction of the kettle car. The mounting plate 121 is provided with a mounting hole 122, and the wheel unit 2 is mounted in the mounting hole 122. In order to improve the stability and the safety of the movement of the kettle vehicle, at least four mounting seats 12 are arranged on the vehicle frame 1. The wheel unit 2 moves along a rail on the ground. The wheel 23 is provided with a track groove 231 adapted to a rail. The dry bearing 22 is arranged between the wheel 23 and the wheel shaft 21, and the dry bearing 22 is tightly matched and connected with the wheel 23, so that the wheel shaft 21 can be lubricated by the solid lubricant of the dry bearing 22, the use of the lubricating oil is not needed, a certain high temperature can be borne, and the service life of the kettle vehicle is prolonged. The limiting sleeve 24 limits the axial position of the wheel 23, so that the kettle cart can run stably.
Referring to fig. 4, in order to further axially limit the wheel 23, a shaft shoulder 211 is disposed on the wheel shaft 21, and a plurality of hemispherical protrusions 212 are disposed on an end surface of the shaft shoulder 211. The height of the shoulder 211 is adapted to the thickness of the dry bearing 22 to avoid friction between the wheel 23 and the shoulder 211. The hemispherical protrusions reduce friction between the shoulders and the dry bearing 22.
In order to further reduce the friction between the wheel 23 and the stop collar 24 and between the dry bearing 22 and the stop collar 24 when the wheel 23 rotates, a flange 221 is arranged at one end of the dry bearing 22, and the flange 221 is abutted to the stop collar 24. Specifically, the flange 221 is also provided with a solid lubricant, and the fixed lubricant can reduce the frictional resistance with the end surface of the stop collar 24.
Rails are required to be matched after the kettle car is assembled, the distance between the rails is predetermined, and if the distance position of the wheels 23 cannot be adjusted, the assembling difficulty of the kettle car and the rails is increased; if a large adjusting gap is reserved between the wheel 23 and the limiting sleeve 24, the running stability of the kettle car is affected, and derailment can be caused in severe cases. Therefore, the mounting plate 121 is connected with a horizontal plate 3, and the horizontal plate 3 is provided with a fine adjustment mechanism 4 for adjusting the position of the stop collar 24.

The horizontal plate 3 is arranged right above the limit sleeve 24, and the position of the wheel 23 can be adjusted through the fine adjustment mechanism 4, so that the track groove 231 of the wheel 23 is always matched with a track, and a larger distance between the wheel part 2 and the limit sleeve 24 is not required to be reserved.
In this embodiment, the fine adjustment mechanism 4 includes an adjustment shaft 41 vertically installed on the horizontal plate 3, and a wedge 42 connected to the adjustment shaft 41. Specifically, the adjusting shaft 41 is in threaded connection with the horizontal plate 3; or an expansion mounting sleeve is arranged on the horizontal plate 3, and the adjusting shaft 41 can slide in the mounting sleeve and can be fixed by a locking nut matched with the expansion mounting sleeve.
When the adjusting shaft 41 moves upwards or downwards, the position of the wedge block 42 can be adjusted, so that the position of the limiting sleeve 24 is adjusted. Specifically, the position limiting sleeve 24 is provided with an inclined surface 241 matched with the wedge block 42, and the inclined surface 241 is arranged obliquely downwards. When the wedge block 42 moves, the limiting sleeve 24 can be driven to move horizontally, so that the position of the wheel 23 assembly is adjusted.
