[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] Embodiment 1:
[0022] like Figure 1-2 As shown, a lifting device for quickly lifting the brake wheel of an overhead crane includes a hanging plate 1, a top plate 2 is welded above the hanging plate 1, a lifting ear 3 is welded on the top plate 2, a lifting buckle 4 is hung on the lifting ear 3, a stop pin 5 is inserted at one end of the top plate 2, and a spring 6 is sleeved on the stop pin 5.
[0023] A plurality of teeth 7 are provided at the top of the hanging plate 1, a vertical plate 8 is welded at one end of the hanging plate 1, the top of the vertical plate 8 is welded to one end of the bottom surface of the top plate 2, the hanging plate 1 is welded to the top plate 2 through the vertical plate 8, and there is a gap between the side of the hanging plate 1 provided with the teeth 7 and the lower bottom surface of the top plate 2 for hanging the brake wheel. The hanging plate 1 is used to hang the brake wheel, and the sharp end of the teeth 7 on the hanging plate 1 is tilted toward the vertical plate 8, thereby increasing the friction between the brake wheel and the hanging plate 1, so that when the brake wheel is hung on the hanging plate 1, the teeth 7 can clamp the brake wheel.
[0024] One end of the top plate 2 away from the vertical plate 8 exceeds the other end of the hanging plate 1 away from the vertical plate 8, and a through hole 9 is formed at the end of the top plate 2 that exceeds the hanging plate 1. The length of the top plate 2 is longer than that of the hanging plate 1, so that the stop pin 5 on the top plate 2 can block the brake wheel from the other end, thereby preventing the brake wheel from sliding off the hanging plate 1 during the hoisting process.
[0025] A baffle 10 is welded to the top of the stop pin 5, and the lower end of the stop pin 5 passes through the through hole 9, and the stop pin 5 is plugged into the top plate 2 through the through hole 9. The stop pin 5 can move up and down in the through hole 9. After the stop pin 5 moves upward, the brake wheel can be inserted from the gap between the hanging plate 1 and the top plate 2, so that the brake wheel is hung on the hanging plate 1. After the stop pin 5 moves downward, the brake wheel is blocked from the outer end of the brake wheel, thereby preventing the brake wheel from slipping.
[0026] One end of the spring 6 is welded on the baffle 10, and the other end of the spring 6 is welded on the top plate 2. The stop pin 5 and the top plate 2 are connected by the spring 6, so that the elastic force of the spring 6 is utilized to realize the extraction and automatic reset of the stop pin 5.
[0027] Embodiment 2:
[0028] like Figure 1-2 As shown, a lifting device for quickly lifting the brake wheel of an overhead crane includes a hanging plate 1, a top plate 2 is welded above the hanging plate 1, a lifting ear 3 is welded on the top plate 2, a lifting buckle 4 is hung on the lifting ear 3, a stop pin 5 is inserted at one end of the top plate 2, and a spring 6 is sleeved on the stop pin 5.
[0029] A plurality of teeth 7 are provided at the top of the hanging plate 1, a vertical plate 8 is welded at one end of the hanging plate 1, the top of the vertical plate 8 is welded to one end of the bottom surface of the top plate 2, the hanging plate 1 is welded to the top plate 2 through the vertical plate 8, and there is a gap between the side of the hanging plate 1 provided with the teeth 7 and the lower bottom surface of the top plate 2 for hanging the brake wheel. The hanging plate 1 is used to hang the brake wheel, and the sharp end of the teeth 7 on the hanging plate 1 is tilted toward the vertical plate 8, thereby increasing the friction between the brake wheel and the hanging plate 1, so that when the brake wheel is hung on the hanging plate 1, the teeth 7 can clamp the brake wheel.
[0030] One end of the top plate 2 away from the vertical plate 8 exceeds the other end of the hanging plate 1 away from the vertical plate 8, and a through hole 9 is formed at the end of the top plate 2 that exceeds the hanging plate 1. The length of the top plate 2 is longer than that of the hanging plate 1, so that the stop pin 5 on the top plate 2 can block the brake wheel from the other end, thereby preventing the brake wheel from sliding off the hanging plate 1 during the hoisting process.
[0031] A baffle 10 is welded to the top of the stop pin 5, and the lower end of the stop pin 5 passes through the through hole 9, and the stop pin 5 is plugged into the top plate 2 through the through hole 9. The stop pin 5 can move up and down in the through hole 9. After the stop pin 5 moves upward, the brake wheel can be inserted from the gap between the hanging plate 1 and the top plate 2, so that the brake wheel is hung on the hanging plate 1. After the stop pin 5 moves downward, the brake wheel is blocked from the outer end of the brake wheel, thereby preventing the brake wheel from slipping.
[0032] One end of the spring 6 is welded on the baffle 10, and the other end of the spring 6 is welded on the top plate 2. The stop pin 5 and the top plate 2 are connected by the spring 6, so that the elastic force of the spring 6 is utilized to realize the extraction and automatic reset of the stop pin 5.
[0033] A pulley 11 is sleeved on the fastening bolt of the hanging buckle 4. The pulley 11 is used to hang on the wire rope, thereby reducing the friction with the wire rope, and avoiding the excessive friction with the wire rope to damage the wire rope when the utility model slides on the wire rope.
[0034] The difference between this embodiment and the first embodiment is that a pulley 11 is sleeved on the lifting buckle 4, so that it can be hung with the hook of the lifting equipment, and an inclined wire rope can be used as a slideway to make the utility model slide down.
[0035] The working principle of the utility model is:
[0036] When in use, hold the top plate 2 with one hand and pull the stop pin 5 upward with the other hand. At this time, the spring 6 is stretched, and then the hanging plate 1 is inserted into the inside of the overhead crane brake wheel. The top plate 2 is located outside the brake wheel, and then the stop pin 5 is released. At this time, the stop pin 5 moves downward under the contraction force of the spring 6, so that a space for accommodating the brake wheel is formed between the top plate 2, the vertical plate 8, the hanging plate 1, and the stop pin 5, and the brake wheel is limited in both the horizontal and vertical directions to prevent the brake wheel from falling off. If other lifting tools are used, such as a hand chain hoist, the hook can be directly hung on the hook 4 to achieve the lifting of the brake wheel. If an inclined steel wire rope is used to transport the brake wheel, the hook 4 can be opened, and after it is hooked on the steel wire rope and the lifting lug 3, the pulley 11 is sleeved and the hook 4 is installed, and a traction rope is tied to the hook 4. The staff pulls the traction rope on the overhead crane to make the pulley 11 roll on the steel wire rope, thereby transporting the brake wheel upward, or slowly lowers the traction rope to transport the brake wheel from top to bottom.
[0037] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
[0038] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
