[0028] 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.

[0029] In view of the problem that the objects being hoisted cannot be fixed in the prior art, which makes the objects shake easily during transportation and thus easily cause the objects to fall, the following solutions can be used to solve the problem:

[0030] See also Figure 1 - Figure 7 As shown, a pneumatic monorail crane with an anti-sway stabilizing structure comprises a track 1, a load-bearing pulley 11 is slidably connected to the track 1, and is used for the pneumatic hoist 13 to slide on the track 1, and the bottom of the load-bearing pulley 11 is fixedly connected to a fixed plate 2 through a plurality of connecting rods 12, and the number of connecting rods 12 is four and they are respectively located at the four corners of the top of the fixed plate 2, thereby enhancing the connection stability between the load-bearing pulley 11 and the fixed plate 2, and two groups of sliding rods 21 are fixedly connected on both sides of the fixed plate 2, and a clamping plate 22 is slidably connected between the two groups of sliding rods 21, and the sliding rods 21 are provided to realize the sliding of the clamping plate 22, and the two groups of sliding rods 21 are easy to adjust. The distance between the clamping plates 22 can realize the clamping and fixing of objects of different widths. A combined pulling rod 23 is installed on the clamping plate 22. The bottom of the load-bearing pulley 11 is located between multiple connecting rods 12 and a pneumatic hoist 13 is fixedly installed. A through hole is penetrated at the center of the top of the fixed plate 2. The rope end of the pneumatic hoist 13 extends to the bottom of the fixed plate 2 through the through hole and is fixedly connected with a hook 14. A linkage component 3 is arranged between the rope of the pneumatic hoist 13 and the combined pulling rod 23. The combined pulling rods 23 on both sides are driven to move relative to each other through the rising rope of the pneumatic hoist 13 and the linkage component 3, thereby automatically realizing the relative movement of the clamping plate 22.

[0031] The linkage assembly 3 includes a fixed seat 31, a movable seat 32 and a support rod 33. The fixed seat 31 is fixedly connected to the rope of the pneumatic hoist 13 below the fixed plate 2. The rope of the pneumatic hoist 13 is raised and lowered, and the fixed seat 31 is driven to move in the same direction. The top of the fixed seat 31 is located outside the rope of the pneumatic hoist 13 and is movably sleeved with a movable seat 32. The support rod 33 is hinged between the movable seat 32 and the corresponding combined pulling rod 23. The rope of the pneumatic hoist 13 drives the fixed seat 31 to rise and contact with the movable seat 32 and push the movable seat 32 to move upward, and the relative movement of the clamping plates 22 on both sides is automatically realized in cooperation with the support rods 33 on both sides and the corresponding combined pulling rod 23.

[0032] The combined pull rod 23 includes a long pull rod 231 and a short pull rod 232, and the long pull rod 231 and the short pull rod 232 are fixedly connected in an L shape. One end of the support rod 33 is hinged to the bottom of the short pull rod 232. The short pull rod 232 is located on the long pull rod 231 on the side of the movable seat 32 away from the corresponding clamping plate 22, and the support rod 33 is hinged to the short pull rod 232 and the movable seat 32, so that when the movable seat 32 rises, the short pull rod 232 is pushed to move away from the movable seat 32, and then the clamping plate 22 is driven to move towards the object through the long pull rod 231.

[0033] The top of the short pull rod 232 is fixedly connected to the limit block 233, and the bottom of the fixed plate 2 is provided with a slide groove 24 which is slidably connected to the corresponding limit block 233. The limit block 233 cooperates with the slide groove 24 to achieve stable sliding of the combined pull rod 23 at the bottom of the fixed plate 2. A return spring 234 is fixedly connected between the side of the limit block 233 away from the movable seat 32 and the inner wall of the corresponding slide groove 24. Through the set return spring 234, when the rope of the pneumatic hoist 13 drives the object to descend, the fixed seat 31 is separated from the movable seat 32, and the combined pull rod 23 drives the clamping plate 22 to reset under the compression of the return spring 234, so that the hoisted object can be easily removed.

[0034] A fixing sleeve 25 is fixedly connected to the clamping plate 22 and is slidably connected to the corresponding long pull rod 231. The position of the clamping plate 22 on the sliding rod 21 is adjusted by the sliding connection between the long pull rod 231 and the fixing sleeve 25. A plurality of adjusting holes 235 are equidistantly provided on the long pull rod 231 along its length direction. An adjusting bolt 26 matched with the adjusting hole 235 is inserted into the fixing sleeve 25. The position-adjusted clamping plate 22 is fixed by the cooperation of the plurality of adjusting holes 235 and the adjusting bolt 26, so as to realize the clamping and fixation of objects of different sizes.

[0035] A receiving groove is provided at the bottom of the clamping plate 22, and an L-shaped plate 27 is slidably connected in the receiving groove. The L-shaped plate 27 provided at the bottom of the clamping plate 22 allows the clamping plate 22 to clamp the object while driving the lateral section of the L-shaped plate 27 to move to the bottom of the object, thereby effectively preventing the object from falling off when the object is prevented from being separated from the hook 14 during transportation. A plurality of adjusting holes 28 are equidistantly provided on the vertical section of the L-shaped plate 27 in the vertical direction. An adjusting bolt 29 that matches the adjusting hole 28 is bolted to the bottom of one side of the clamping plate 22. The height of the L-shaped plate 27 can be adjusted by cooperating with the receiving groove on the clamping plate 22, the plurality of adjusting holes 28 on the L-shaped plate 27 and the adjusting bolt 29, so as to achieve anti-fall protection for objects of different heights.

[0036] The working process and principle of the utility model are as follows:

[0037] During use, the utility model utilizes the pneumatic hoist 13 and the hook 14 to lift the object. The fixed seat 31 on the rope of the pneumatic hoist 13 contacts the movable seat 32 during the rising process and pushes the movable seat 32 to move synchronously. When the movable seat 32 rises, the corresponding support rod 33 pushes the short pull rod 232 to move away from the movable seat 32, and the long pull rod 231 pulls the clamping plate 22 to move toward the object, clamping and fixing both sides of the hoisted object to avoid shaking of the object during transportation, so as to improve the transportation stability. While the clamping plate 22 clamps the object, it drives the lateral section of the L-shaped plate 27 to move to the bottom of the object to prevent the hoisted object from falling.

[0038] When lifting objects of different sizes, rotate the adjusting bolt 26 to separate it from the corresponding adjusting hole 235, and adjust the position of the clamping plate 22 on the slide rod 21. Then, rotate the adjusting bolt 26 in the opposite direction to connect it with the adjusting hole 235 at that position to complete the fixation of the clamping plate 22. Rotate the adjusting bolt 29 to separate it from the corresponding adjusting hole 28, and adjust the height of the L-shaped plate 27 up and down. Then, rotate the adjusting bolt 29 in the opposite direction to connect it with the adjusting hole 28 at that position to complete the fixation of the L-shaped plate 27, thereby achieving the stability of objects of different sizes during the lifting process.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
