[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-3 The utility model provides an embodiment: a crane trolley anti-derailment device, comprising a guide rail body 1, wherein limit grooves 2 are provided on the upper parts of the front and rear sides of the guide rail body 1, and limit blocks 3 are slidably connected inside the limit grooves 2. A connecting plate 4 is fixedly connected to the side of the limit block 3 away from the limit groove 2, and a connecting block 5 is fixedly connected to the opposite side of the two connecting plates 4, and a trolley body 6 is fixedly connected to the opposite side of the two connecting blocks 5, and a roller 7 is arranged at the lower part of the trolley body 6, and the roller 7 is rotatably connected to the bottom of the guide rail body 1.

[0028] The trolley body 6 is driven to move by the rotation of the roller 7, the movement of the trolley body 6 drives the connecting block 5 to move, the connecting block 5 drives the connecting plate 4 to move, the connecting plate 4 drives the limit block 3 to slide inside the limit groove 2, and the crane trolley is limited by the cooperation among the limit groove 2, the limit block 3, the connecting plate 4 and the connecting block 5.

[0029] Reference Figure 1-3 , an anti-derail assembly is arranged inside the guide rail body 1, and the anti-derail assembly comprises a pressure sensing pad 8, a support plate 9 and a buzzer alarm 11, the pressure sensing pad 8 is fixedly connected to the front and rear sides of the inner wall of the guide rail body 1, the support plate 9 is fixedly connected to the upper left side of the guide rail body 1, the buzzer alarm 11 is fixedly connected to the lower part of the support plate 9, the buzzer alarm 11 is electrically connected to the pressure sensing pad 8, the pressure sensing pad 8 is electrically connected to the trolley body 6, and a monitoring device 10 is fixedly connected to the upper part of the support plate 9, and the input end of the monitoring device 10 is always located on the left side of the trolley body 6.
