The development and use of cranes in the market are becoming more and more extensive.

[0003] There are various existing cranes. For example, the bridge crane used in warehouses mostly uses a hoisting trolley for reciprocating transportation on the track. During the long-term use of the hoisting trolley of the above-mentioned crane, it will continuously move back and forth on the track. After long-term use, there is a risk of derailment. Once derailed, due to the large self-weight of the hoisting trolley, it is very difficult to reset it. The human, material, time, and cost wasted during this period are extremely large.

[0004] In response to the above problems, corresponding solutions have emerged in the industry. For example, the Chinese authorized utility model patent with the authorization announcement number: CN220998993 U and the patent name of a derailment reset device for a crane. In the above patent, when the hoisting trolley derails, multiple hydraulic jacks are set to jack up the hoisting trolley so as to reset the hoisting trolley, solving the problem in the prior art that it is very difficult to reset the hoisting trolley due to its large self-weight.

[0005] However, in the above patent, only two hydraulic jacks are placed on one side of the hoisting trolley. When the hoisting trolley derails on the side without the hydraulic jack, it still mostly requires manual lifting of the hoisting trolley for reset, resulting in a high cost for resetting the hoisting trolley and not meeting the actual working needs.

The T-shaped groove 402 penetrates from one end to the other end in the length direction of the slide rail body 401. A plurality of connecting through holes 403 are further provided on the upper surface of the slide rail body 401. The connecting through holes 403 penetrate from the upper surface of the slide rail body 401 to the T-shaped groove 402.

[0032] In order to play a fixing role, further, the slider support base 5 has a U-shaped structure. The slider support base 5 includes a horizontal bottom plate 501. A first vertical plate 502 and a second vertical plate 503 are respectively provided on both sides of the horizontal bottom plate 501. An upper support 504 is provided at the top of the first vertical plate 502. A sliding plate 505 is provided at the top of the second vertical plate 503. The lifting cylinder 6 is installed on the upper support 504.

[0033] In order to increase the strength, further, a plurality of inclined support plates 506 are respectively provided between the horizontal bottom plate 501, the first vertical plate 502 and the second vertical plate 503.

[0034] In order to move the reset device 3, further, the connecting support plate 7 has a plate-like structure. An intermediate chute 701 is provided on the connecting support plate 7. The reset moving seat 8 moves along the intermediate chute 701.

[0035] In order to fix the reset moving seat 8, further, the reset moving seat 8 has an I-shaped structure. A plurality of push screw holes 801 are provided on the upper surface of the reset moving seat 8. A push screw 802 is engaged in the push screw holes 801.
