[0017] The utility model will be combined with the drawings and specific embodiments to make further detailed description, but not limited to this, any in the basic spirit of the utility model embodiment improvement or alternative, still belongs to the utility model wants to protect the range.

[0018] As Figure 1 and 2 The transit track vehicle provided by the utility model comprises a vehicle body 1, a guide roller assembly and an adjusting assembly are arranged on the vehicle body 1, the guide roller assembly comprises a mounting frame 2 and a plurality of guide rollers 3 arranged on the mounting frame 2, a damping mechanism capable of increasing the rotating resistance of the guide rollers 3 is further arranged on the mounting frame 2, the adjusting assembly comprises a lifting frame 4 and a plurality of guide wheels 5 arranged on the lifting frame 4, the lifting frame 4 is located below the mounting frame 2 and is connected with a lifting mechanism, the guide wheels 5 are located between adjacent two guide rollers 3, and the axis of the guide wheels 5 is perpendicular to the axis of the guide rollers 3.

[0019] When in use, a track can be arranged on the ground at the end of the conveying line of each processing procedure, and the transfer track vehicle is installed on the track and can move on the track, and the workpiece is transferred between the conveying lines of each processing procedure. The track vehicle can automatically move on the track through the driving mechanism and wheels arranged on the track vehicle. When the workpiece is processed by one processing procedure and is conveyed to the end of the conveying line corresponding to the processing procedure, the workpiece is received by the transfer track vehicle which is previously stopped at the end of the conveying line, and the workpiece moves on the guide roller 3 under the action of inertia. The rotation of the guide roller 3 can smoothly transfer the workpiece to the track vehicle. When the number of workpieces on the track vehicle reaches a predetermined number, the damping mechanism is used to apply resistance to the guide roller 3 to prevent the guide roller 3 from rotating during the movement of the track vehicle, which can cause the workpiece to fall. When the track vehicle moves along the track to the end of the conveying line of the next processing procedure, the damping mechanism is released, and the resistance applied by the damping mechanism to the guide roller 3 is removed, so that the guide roller 3 can rotate by itself and push the workpiece towards the conveying line to send the workpiece into the conveying line of the processing procedure. If the workpiece deviates from the position of the conveying line, the lifting mechanism can be used to lift the lifting frame 4, so that the guide wheel 5 on the lifting frame 4 rises and protrudes above the highest point of the guide roller 3. At this time, the guide wheel 5 lifts the workpiece, and the guide wheel 5 can rotate when the workpiece is pushed, so that the position of the workpiece can be adjusted to align the workpiece with the corresponding conveying line. After the adjustment is completed, the lifting mechanism is reset, and the workpiece is supported on the guide roller 3 again. It is especially suitable for the transfer of heavy workpieces.

[0020] As shown in Figure 1 some embodiments, in order to facilitate the unloading operation of the transfer track vehicle, one end of the mounting frame 2 is hinged to the vehicle body 1, and the other end is hinged to the jacking mechanism 6, and the bottom of the jacking mechanism 6 is hinged to the vehicle body 1. When the jacking mechanism 6 is lifted, the mounting frame 2 can be in an inclined state, and the automatic unloading of the workpiece can be facilitated. The jacking mechanism 6 can be selected from a gas cylinder, an oil cylinder or an electric push rod.

[0021] As shown in Figure 2 and 3 specifically, in some embodiments, the damping mechanism includes a mounting rod 7, the mounting rod 7 is provided with a damping block 8 corresponding to the guide roller 3, the mounting rod 7 is slidably connected to the mounting frame 2, and the mounting rod 7 further has an adjusting bolt 9. The damping block 8 can be made of rubber material, and the position of the mounting rod 7 on the mounting frame 2 can be adjusted by the adjusting bolt 9, so that the damping block 8 can be in contact with or separated from the guide roller 3. In order to facilitate the operation, a hand wheel can be further arranged on the adjusting bolt 9.

[0022] As shown in Figure 2 and 3As shown, specifically, the mounting rod 7 is provided with a sliding groove 71 at both ends, the mounting frame 2 is provided with a sliding block 21 at both ends, the sliding block 21 is connected with the sliding groove 71, the mounting rod 7 is provided with a through hole communicated with the sliding groove 71 at one end, the adjusting bolt 9 is rotatably connected with the sliding block 21 through the through hole, and the adjusting bolt 9 is threadedly connected with the through hole. Rotating the adjusting bolt 9 can make the mounting rod 7 move relative to the mounting frame 2, thereby adjusting the cooperation state between the damping block 8 and the guide roller 3.

[0023] As shown, Figure 2 More specifically, in order to facilitate the cooperation between the damping block 8 and the guide roller 3, the rotating shaft of the guide roller 3 extends out of the mounting frame 2 at one end, and the damping block 8 is provided with an arc-shaped concave surface matched with the shape of the rotating shaft of the guide roller 3. When the damping block 8 and the rotating shaft of the guide roller 3 are in contact and cooperation, the guide roller 3 can be provided with resistance to prevent its own rotation.

The above-mentioned jacking mechanism 6 can also be arranged on the support frame 10 and hinged with the support frame 10.

[0025] As shown, Figure 1 In some embodiments, the lifting mechanism includes a scissor mechanism and a power mechanism 13 connected with the scissor mechanism. Specifically, as shown, the scissor mechanism includes a first scissor arm 11 and a second scissor arm 12 rotatably connected together in the middle, one end of the first scissor arm 11 is arranged in the slide rail 14 of the lifting frame 4, the other end is hinged with the support frame 10, one end of the second scissor arm 12 is hinged with the lifting frame 4, the other end is arranged in the slide rail 14 of the support frame 10, and the power mechanism 13 is arranged on the support frame 10 and connected with the second scissor arm 12. The power mechanism 13 can be a gas cylinder, an oil cylinder or an electric push rod. When the power mechanism 13 drives one end of the second scissor arm 12 to move in the slide rail 14 of the support frame 10, the gathering or separation of the scissor mechanism can be realized, thereby driving the lifting frame 4 to lift, and further making the guide wheel 5 protrude from the highest point of the guide roller 3 or be lower than the highest point of the guide roller 3. In order to facilitate the installation of the guide wheel 5, a fixed rod 15 can be installed on the lifting frame 4, and the guide wheel 5 is rotatably installed on the fixed rod 15.
