[0015] 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.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0017] like Figure 1 , Figure 2 As shown, a lifting trolley structure with an extra-long lifting point includes a cantilever beam 1, fixed pulley blocks 2 are arranged on the left and right sides of the cantilever beam 1, the fixed pulley blocks 2 are connected to a lifting mechanism 7, and the fixed pulley blocks 2 are transmission-connected with a movable pulley block 3, and the movable pulley block 3 is arranged on an extra-long lifting point hanging beam 5; a trolley frame 6 is also arranged on the cantilever beam 1, and a trolley running mechanism 8 is arranged on the trolley frame 6.

[0018] Furthermore, an anti-tipping hook 10 is fixedly connected to the trolley frame 6. The anti-tipping hook 10 is an L-shaped hook. The top of the L-shaped hook is fixed to the trolley frame 6, and the bottom hook portion of the L-shaped hook is located at the bottom of the main beam 9. Driven by the trolley running mechanism 8, the trolley running mechanism 8 and its trolley frame 6 run together on the main beam 9. In this way, when the lifting trolley structure with an extra-long lifting point is a double-sided cantilever, it is easy to cause uneven center of gravity of the hoisted materials, causing the center of gravity to shift, causing the trolley to tip over, because the anti-tipping hook 10 can hook the bottom of the main beam 9, thus preventing the trolley running mechanism 8 from tipping over, thereby ensuring the safety of the lifting process.

[0019] Furthermore, the cantilever beam 1 and the trolley frame 6 are welded into one body.

[0020] Furthermore, the lifting mechanism 7 adopts a single drum, and both sides of the single drum are wound with steel wire ropes to connect the two fixed pulley groups 2, and on the steel wire rope connecting the lifting mechanism 7 and the fixed pulley groups 2 on both sides, a rope pressing device 4 is provided on one side, and a rope top device 11 is provided on the other side, so that the rope pressing device 4 and the rope top device 11 respectively control the steel wire rope jumping groove and the angle of the steel wire rope. It should be noted that the rope pressing device 4 includes a rope pressing device body, a pressure roller is provided on the rope pressing device body, and the steel wire rope is located below the pressure roller. The rope top device 11 includes a rope top device body, a roller is provided on the top of the rope top device body, and the steel wire rope is located above the roller. The utility model effectively prevents the steel wire rope from slipping out of the groove and damaging the steel wire rope through the function of the roller of the rope top device 11, thereby avoiding accidents.

[0021] Furthermore, a fixed rope device 12 is provided on the trolley frame 6, and a pin shaft 13 is provided on the fixed rope device 12. In this way, the end of the wire rope is fixed on the pin shaft 13, which can avoid the fixed end of the wire rope from squeezing the movable pulley block 3 during lifting, thereby ensuring the service life.

[0022] Furthermore, the length of the super-long suspension point beam 5 is longer than the length of the cantilever beam 1 .

[0023] The working principle of the utility model is:

[0024] The extra-long hanging point hanging beam 5 is suspended on the cantilever beam 1 equipped with the trolley structure, and the fixed pulley block 2 and the movable pulley block 3 are arranged at a distance, so that the hanging point spacing can be lengthened. The material handling is solved by the extra-long hanging point hanging beam 5, and the extra-long material is prevented from bending, being damaged, and being unusable.

[0025] The rope pressing device 4 controls the wire rope jumping and the wire rope angle, and the single drum is wound with ropes on both sides. The movable pulley block 3 is fixed on the extra-long lifting point hanging beam 5. This extra-long lifting point lifting trolley can be used for multiple purposes, which can effectively prevent the extra-long materials from being unable to be lifted and the extra-long objects required by special industries from being unable to be transported.

[0026] Thus, the utility model adopts a single drum, two steel wire ropes, two sets of movable and fixed pulley blocks, two sets of rope pressing devices 4, and the bidirectional cantilever of the trolley opens the lifting point interval, which is suitable for the working condition requiring extra-long lifting points for lifting materials.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
