Description

Technical Field

[0001] The utility model relates to the technical field of tractors, in particular to a novel tractor for glass loading racks. Background Art

[0002] The loading rack (A-frame) is a commonly used glass transport vehicle in the tempered glass homogenizing furnace. At present, the tempered glass on the loading rack is basically pushed in and out of the tempered glass homogenizing furnace by manpower during the process of entering and exiting the tempered glass homogenizing furnace. The labor cost is high, time-consuming and labor-intensive, and the stability is difficult to control. When the glass loading rack is loaded with a lot of glass, the friction between the tractor and the track is limited, and it is difficult to ensure that the tractor can drive the glass loading rack to move on the track.

[0003] In order to solve the above problems, the utility model patent with authorization announcement number CN216837685U discloses a tempered glass loading rack tractor, which increases the friction between the tractor and the track by loading weight-added materials such as crushed sand and gravel in the weighing box, thereby improving traction.

[0004] However, in actual use, increasing the friction between the tractor and the track by adding crushed sand and gravel is a cumbersome operation and cannot well meet the use requirements. Utility Model Content

In this embodiment, the chassis 1 is also equipped with an electric pump 13 for supplying oil to the hydraulic cylinder 45.

[0028] The working principle of the present invention is as follows: when it is necessary to tow the glass loading rack, the glass loading rack is hooked on the connecting hook 44, and then the hydraulic cylinder 45 pushes the hydraulic lifting seat 42 upward to bear part of the weight of the glass loading rack, thereby increasing the pressure of the tractor on the track, and then increasing the friction between the tractor and the track. The operation is simple and easy to adjust, ensuring that the tractor can drive the glass loading rack to move on the track. The track driving mechanism 3 can drive the glass loading rack to move on the track, thereby better meeting the use requirements.

[0029] As a further solution, it further includes a ground traveling mechanism 2, which is mounted on the chassis 1 and is used to drive the glass loading rack to move on the ground; the ground traveling mechanism 2 includes an adjustment assembly mounted on the upper end of the chassis 1 and a roller assembly mounted on the lower end of the chassis 1;

[0031] The adjustment assembly includes a lifting bracket 21 mounted on the upper end of the chassis 1, a lifting rotation shaft 22 is rotatably mounted in the lifting bracket 21, a pair of travel connecting plates 23 are mounted on the lifting rotation shaft 22, the front ends of the pair of travel connecting plates 23 are hingedly connected to a hydraulic jack seat plate 26, the rear end of each travel connecting plate 23 passes through the chassis 1 and is hingedly connected to a travel connecting rod 24, the rear end of the travel connecting rod 24 is hingedly connected to an auxiliary rod 254 on the front half of the corresponding travel bracket 251;

[0032] A hydraulic jack 28 is also rotatably installed on the upper end of the hydraulic jack seat plate 26, and the telescopic end of the hydraulic jack 28 is rotatably inserted into the slot at the lower end of the lifting bracket 21.

The auxiliary gear 34 is meshed with the driving gear 33 and the corresponding driving gear 35.

[0036] The working principle of the track drive mechanism 3 is: when the track roller 36 is placed on the track, the drive motor 32 is started, and the drive motor 32 drives the drive shaft 31 to rotate, thereby driving the driving gear 33 to rotate, and cooperates with the auxiliary gear 34 to drive the corresponding drive gear 35 to rotate, thereby realizing the rotation of the track roller 36, thereby realizing the automatic movement of the device on the track.
