[0029] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The embodiment of the present application discloses a transport device for a bridge crane, such as Figure 1 and 2As shown, the structure comprises a fixed block 1 and an electric hoist 2. The fixed block 1 is fixedly mounted on the bridge deck and is fitted with a fixed ring 11. The electric hoist 2 is mounted with a first hook 21, which is inserted into the fixed ring 11. The output end of the electric hoist 2 is connected to a second hook 22, which is used to pull the crane. To move the crane, the operator activates the electric hoist 2. The fixed block 1 supports the fixed ring 11, which in turn supports the first lifting ring, allowing the second lifting ring to pull the crane.
[0032] like Figure 1 As shown, the crane also includes a connecting rope 3, which is installed on the side of the crane facing the electric hoist 2. Both ends of the connecting rope 3 are connected to the crane, and a second hook 22 is hooked on the middle of the connecting rope 3. The second hook 22 can apply tension to the connecting rope 3, and the connecting rope 3 can apply tension to the crane, thereby achieving crane transportation; the connecting rope 3 can provide a buffer to reduce the possibility of crane deviation.
[0033] like Figure 3 As shown, it also includes a plurality of support blocks 4. In the embodiment of the present application, the number of support blocks 4 is six. The support blocks 4 are fixedly mounted on the bridge deck, and a guide slope 41 is provided on the support blocks 4. The support blocks 4 can provide support for the crane, reducing the possibility of direct contact between the crane and the bridge deck. The guide slope 41 can provide a moving guide for the crane when it moves, making it easier for the crane to move onto the support blocks 4, thereby facilitating the support of the crane by the support blocks 4. A connecting rod 42 is fixedly connected between two adjacent support blocks 4. The connecting rod 42 can increase the connection strength between the two adjacent support blocks 4, and is also convenient for adjusting the distance between the support blocks 4, so that the support blocks 4 can be installed at the appropriate position on the bridge deck, thereby facilitating the support of the crane by the support blocks 4.
[0034] like Figure 3 As shown, guide plates 43 are fixedly connected to the support block 4. The guide plates 43 extend in the vertical direction and are located on either side of the crane. Rollers 44 are rotatably connected to the guide plates 43 and contact the crane. When the crane moves on the support block 4, the rollers 44 come into contact with both sides of the crane, converting the hard friction between the crane and the guide plates 43 into rolling friction, reducing the friction experienced by the crane during movement and facilitating crane transportation. The rollers also further limit the crane's position, reducing the possibility of deviation during movement.
[0035] like Figure 1As shown, the structure further includes a support frame 5, which is fixedly mounted on the bridge deck. A reduction motor 51 is fixedly mounted on the support frame 5. A rotating roller 52 is rotatably connected to the support frame 5, and the output shaft of the reduction motor 51 is fixedly connected to the rotating roller 52. An auxiliary rope 53 is wound around the rotating roller 52, and the end of the auxiliary rope 53 away from the rotating roller 52 is connected to the crane. When the crane needs to transport, the operator can drive the reduction motor 51, so that the output shaft of the reduction motor 51 drives the rotating roller 52 to rotate. The rotation of the rotating roller 52 drives the movement of the auxiliary rope 53, and the auxiliary rope 53 can pull the crane, facilitating the movement of the crane on the support block 4.
[0036] like Figure 1 As shown, the bridge also includes an infrared sensor 6, which includes an infrared transmitter 61 and an infrared receiver 62. The infrared transmitter 61 is mounted on the bridge deck, and the infrared receiver 62 is mounted on the crane. When the crane moves on the support block 4, the movement of the crane drives the movement of the infrared receiver 62. When the crane moves to a suitable position, the infrared receiver 62 receives the signal from the infrared transmitter 61, allowing the operator to stop the crane and move it to the appropriate position.
[0037] The implementation principle of a transport device for a bridge crane in the embodiment of the present application is as follows:
[0038] When the crane needs to be transported, the operator drives the electric hoist 2 and the reduction motor 51, the electric hoist 2 pulls the connecting rope 3 through the second hook 22, the reduction motor 51 can drive the movement of the rotating roller 52, the rotating roller 52 can pull the auxiliary rope 53, the connecting rope 3 and the auxiliary rope 53 can pull the movement of the crane, so that the crane moves on the support block 4; the guide slope 41 can provide a moving guide for the crane when it moves, and the roller 44 can limit the crane when it moves. When the crane moves to a suitable position, the infrared receiving end 62 can receive the signal sent by the infrared transmitting end 61, so that the operator can stop moving the crane, thereby facilitating the crane to move to a suitable position.
[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
