Description

Technical Field

[0001] The utility model relates to the technical field of rail trolleys, and more specifically, to an anti-skid climbing rail trolley. Background Art

[0002] In order to save manpower and improve production efficiency, more and more manufacturing plants use rail trolleys to transfer products. Most of the rail trolleys currently used on the market move in the horizontal direction and will not cause any abnormal phenomena. However, when the trolley moves on a slope, the friction between the rollers and the track is small, and the trolley will slide down due to the influence of inertia. People have to push the trolley from behind, or move the items off the trolley by manual climbing, which brings trouble to the transfer of items on the production line. For this reason, an anti-slip climbing rail trolley is proposed.

[0003] After searching, for example, a Chinese patent application with publication number CN212401199U discloses an anti-slip climbing rail trolley, in which the first roller rolls and moves on the top of the second fixed block, and the serrations of the second roller are inserted into the inside of the top opening of the first fixed block, so that the friction between the second roller and the first fixed block is increased, thereby achieving an anti-slip effect; the trolley has its own power supply group, and there is no need to connect a power cord externally. The controller is used to control the operation and stop of the motor, and the motor drives the second roller to rotate. At the same time, the first roller is driven to rotate and stop through the first chain and the second chain, thereby increasing the power for climbing.

[0004] However, when the above solution is used, the trolley travels on the track via rollers. When the trolley passes through a track with a large slope angle, the workpiece in the trolley will slide backward, resulting in an unstable center of gravity, which may easily cause the trolley to roll over and affect safety. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an anti-skid climbing track trolley, and the technical problem to be solved is that the track trolley is prone to rollover when climbing a track with a large slope.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-skid climbing track trolley, comprising a loading box:

[0007] A mobile vehicle is fixed at the lower end of the loading box, and four connecting frames are fixed at the lower end of the mobile vehicle. Two rotating shafts are respectively passed through the inner sides of the four connecting frames, and toothed wheels are respectively fixed at both ends of the rotating shafts. Tracks are respectively provided at the lower ends of the toothed wheels, and two of the tracks are fixed to the ground. A connecting plate is fixed between the two tracks.

[0008] The lower end of the mobile vehicle is provided with two anti-rollover protection devices capable of towing the mobile vehicle, for towing the mobile vehicle to move;

[0009] The anti-rollover protection device includes a connecting seat, which is fixedly arranged at the lower end of the mobile vehicle, and a hinge block is hinged inside the groove at the lower end of the connecting seat through a hinge column;

[0010] The outer surface of the rotating shaft is provided with two anti-skid stopping devices that can prevent the toothed wheel from rotating backwards, and are used to prevent the loading box from moving backwards.

[0011] In a preferred embodiment, a connecting column is fixedly provided at the lower end of the hinge block, a mounting frame is fixedly provided at the lower end of the connecting column, and four rollers are movably provided inside the mounting frame.

[0012] In a preferred embodiment, an H-shaped track is fixedly provided on the upper end of the connecting plate, and the four rollers are respectively located on both sides of the H-shaped track.

[0013] In a preferred embodiment, the anti-slip stopping device includes two connecting plates, the two connecting plates are fixedly arranged at the lower end of the moving vehicle, and the rotating shaft passes through the inner sides of the two connecting plates.

[0014] In a preferred embodiment, a ratchet is fixedly provided on the outer surface of the rotating shaft, a hinged rod is fixedly provided between the two connecting plates, a pawl is hingedly provided on the outer surface of the hinged rod, and the pawl is located at the upper end of the ratchet.

[0015] In a preferred embodiment, a fixing block is fixed between the connecting plates, a spring piece is fixed at the lower end of the fixing block, and the spring piece is located at the upper end of the pawl.

[0016] In a preferred embodiment, a chain gear is fixedly provided on the outer surface of the rotating shaft, a chain motor is fixedly provided on the lower end of the mobile vehicle through a bracket, the chain gear and the chain motor are connected through a chain transmission, a battery is fixedly provided on the lower end of the mobile vehicle, and a controller is fixedly provided on one side of the loading box.

[0017] The technical effects and advantages of this utility model are:

[0018] The utility model is fixed to the connecting plate through the H-shaped track. When the mobile vehicle moves, the four rollers will move on both sides of the H-shaped track. By utilizing the articulation of the connecting seat and the articulated block, when the mobile vehicle climbs a slope, the rollers can adapt to the arc of the climbing slope. Therefore, when the workpiece loaded in the loading box slides to one side when climbing the slope, the connecting seat is used to pull the mounting frame and the rollers, and then the H-shaped track is used to limit the position, thereby avoiding the problem of the utility model rolling over, thereby improving the safety of the utility model.

[0019] The utility model rotates the rotating shaft by moving the mobile vehicle. When climbing a slope, the ratchet and the pawl cooperate to prevent the rotating shaft from reversing, thereby causing the utility model to slide. The pawl is supported by the spring piece and can limit the reversal of the ratchet at all times, thereby achieving an anti-slip climbing effect as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

A battery 11 is fixed at the lower end of the mobile car 4, and a controller 13 is fixed on one side of the loading box 1.

[0027] In order to avoid the problem of rollover of the present invention and improve the safety of the present invention, two anti-rollover protection devices 2 capable of towing the mobile vehicle 4 are provided at the lower end of the mobile vehicle 4 for towing the mobile vehicle 4 to move;

[0028] like Figure 3 As shown, the anti-rollover protection device 2 includes a connecting seat 22, which is fixedly arranged at the lower end of the mobile vehicle 4. The groove at the lower end of the connecting seat 22 is hinged with a hinge block 24 through a hinge column. The lower end of the hinge block 24 is fixed with a connecting column 23, and the lower end of the connecting column 23 is fixed with a mounting frame 25.

On the connecting plate 10, when the mobile vehicle 4 moves, the four rollers 26 will move on both sides of the H-shaped track 21, and the connection between the connecting seat 22 and the hinge block 24 is utilized. Therefore, when the mobile vehicle 4 climbs a slope, the rollers 26 can adapt to the arc of the climbing slope, so that when the workpiece loaded inside the loading box 1 slides to one side when climbing the slope, the connecting seat 22 is utilized to pull the mounting frame 25 and the rollers 26, and then through the limitation of the H-shaped track 21, the problem of the utility model rolling over is avoided, thereby improving the safety of the utility model.

[0029] Furthermore, in order to achieve the anti-slip climbing effect of the present invention, the outer surface of the rotating shaft 6 is provided with two anti-slip stopping devices 3 that can prevent the toothed wheel 7 from reversing, and are used to prevent the loading box 1 from reversing;

A ratchet 32 ​​is fixedly arranged on the outer surface of the rotating shaft 6, and a hinged rod 33 is fixedly provided between the two connecting plates 31. A pawl 34 is hinged on the outer surface of the hinged rod 33, and the pawl 34 is located at the upper end of the ratchet 32. A fixed block 36 is fixed between the connecting plates 31, and a spring piece 35 is fixed at the lower end of the fixed block 36. The spring piece 35 is located at the upper end of the pawl 34. The moving vehicle 4 rotates the rotating shaft 6. When climbing a slope, the present invention prevents the rotating shaft 6 from reversing through the cooperation of the ratchet 32 ​​and the pawl 34, thereby causing the present invention to slide. The pawl 34 is supported by the spring piece 35, and can always limit the reversal of the ratchet 32, thereby achieving the anti-skid climbing effect as a whole.

[0031] The working principle is as follows: when the present invention is in use, the workpiece is loaded through the transfer box 1, the operation controller 13 controls the chain motor 12, and then the chain is used to drive the chain gear 9 and the rotating shaft 6 to rotate, so that the cooperation of the toothed wheel 7 and the toothed track 8 can drive the present invention to move. When climbing a slope, the anti-rollover protection device 2 can prevent the present invention from rolling over, and the anti-slip stopping device 3 can prevent the present invention from sliding, thereby improving the safety of the present invention as a whole.

[0032] In addition, it is worth noting that the control process of electrical equipment such as the chain motor 12 in the present invention is implemented by the controller 13. The control circuit of the controller 13 is powered by the battery 11. Its circuit structure belongs to the mature existing technology, so it will not be further described in the present invention.
