[0022] like Figures 1-4 The illustration shows a special hoisting tool for hazardous waste disposal containers, comprising a lifting beam 1 and a hanging frame 4. Four lifting hooks 2 are mounted on the lifting beam 1, the top surface of which is rectangular. The four lifting hooks 2 are installed at the four corner points of the rectangle. Two symmetrically arranged lifting seats 3 are mounted on the top surface of the lifting beam 1, with lifting point shafts 31 fixedly threaded through them. The lifting point shafts 31 are used to connect to the lifting hooks of a trolley. Since the hazardous waste disposal container has a heavy full-load weight, and the trolleys used in rigid landfills are double-trolley trolleys with two lifting hooks, two lifting seats 3 are designed to connect to the trolley's lifting hooks. The two lifting trolleys simultaneously lift and lower to drive the lifting beam 1. This utility model uses two hanging frames 4, which are connected parallel to each other on the top of the hazardous waste disposal container. The hanging frames 4 are installed and fixed after the hazardous waste container is filled and sealed. The two hanging frames 4 form a fixed connection with the hazardous waste disposal container, and the hazardous waste disposal container can be moved by lifting the hanging frames 4. Figure 2 As shown, the four lifting tools 2 are divided into two symmetrically arranged groups (left and right). The two groups of lifting tools 2 are installed symmetrically, and each group of lifting tools 2 corresponds to a hanging frame 4. The lifting tool 2 includes a rotatably mounted hook plate 23, which can hook and connect to the hanging frame 4. When lifting, the lifting tool 23 hooks and connects to the hanging frame 4 to realize the lifting of the hazardous waste disposal box. The hook plate 23 has a remote control rotation function. After the hazardous waste disposal box is lifted into the warehouse, the lifting tool 2 is automatically detached from the hanging frame 4 by controlling the rotation of the hook plate 23. After the application of this utility model, there is no need for workers to enter the warehouse to perform the unhooking operation, which can effectively avoid operational safety risks.

[0023] To reduce the total weight of the lifting appliance, the lifting appliance beam 1 can be designed as a box beam structure, and reinforcing rib plates are installed on the lifting appliance beam 1 to consolidate the strength of the box body, especially the positions below the hook tool 2 and the hoisting seat 3.

[0024] As shown in Figure 1 and Figure 3 The hook tool 2 also includes a hook seat 21 and a hook driving assembly 24, the hook seat 21 is fixedly connected to the top surface of the lifting appliance beam 1, the load-bearing shaft 22 is fixedly arranged on the hook seat 21, the hook piece 23 is rotatably installed on the load-bearing shaft 22, the hook driving assembly 24 is installed on the side of the hook seat 21, the hook driving assembly 24 is in transmission connection with the hook piece 23, and the load-bearing shaft 22 plays a role of bearing stress during the process of lifting the hazardous waste disposal box by the hook piece 23, the hook driving assembly 24 is only responsible for driving the hook piece 23, the hook piece 23 is rotatably connected to the load-bearing shaft 22 at the middle segment, the thickness of the middle segment of the hook piece 23 is increased, the driving head 231 is arranged at the top of the hook piece 23, the curved hooking head 232 is arranged at the bottom of the hook piece 23, the hook driving assembly 24 includes a push cylinder support 241 and a push cylinder 242, the push cylinder support 241 is fixedly connected to the top surface of the lifting appliance beam 1, the cylinder head end of the push cylinder 242 is hingedly connected to the push cylinder support 241, the piston rod end of the push cylinder 242 is hingedly connected to the driving head 231 of the hook piece 23, when the piston rod of the push cylinder 242 is retracted, the hook piece 23 and the hooking head 232 are driven to perform outward turning rotation, so that the unhooking effect is formed, when the piston rod of the push cylinder 242 is extended, the hook piece 23 and the hooking head 232 are driven to perform inward turning rotation, so that the hooking effect is formed, in the utility model, the push cylinder 242 is an electric cylinder, the control wire is extended and connected to the crane driving cabin, and the rotation of the hook piece 23 is remotely controlled by the crane driver.

[0025] As shown in Figure 4As shown, the hanger 4 includes a crossbeam 41 and a box connecting plate 42, two box connecting plates 42 are respectively fixedly connected to the two ends of the crossbeam 41, the box connecting plate 42 is vertically installed, the box connecting plate 42 is correspondingly connected to the outer wall of the hazardous waste disposal box, the spacing between the two box connecting plates 42 matches the thickness of the disposal box at the installation position of the box connecting plate 42, the box connecting plate 42 is bolted to the outer wall of the hazardous waste disposal box, the connection position of the box connecting plate 42 needs to be strengthened, the design of the box connecting plate 42 makes the hoisting stress design rational, the stress is transmitted to the side wall of the disposal box, and the arching of the top cover of the disposal box will not be caused, the crossbeam 41 of the utility model adopts an I-shaped cross section, two symmetrical hooking areas 411 are arranged on the length direction of the crossbeam 41, the hooking area 411 is arranged close to the end of the crossbeam 41, and the design is also for rationalizing the stress condition. Since the hooking area 411 is close to the box connecting plate 42, the stress is borne by the box connecting plate 42, and the abnormal deformation (destructive arching) of the crossbeam 41 will not occur during hoisting. Two hooking areas 411 are designed and arranged corresponding to two lifting hook tools 2 in the same group of lifting hook tools 2. The utility model is provided with two vertical rib plates 412 installed on the hooking area 411. The two rib plates 412 not only strengthen the hanging position, but also form a falling position containing the lifting hook piece 23. The spacing between the two rib plates 412 is greater than the thickness of the lifting hook piece 23. After the lifting hook piece 23 rotates, it can be smoothly inserted into the space between the two rib plates 412. As shown in Figure 3 As shown, the bottom surface of the upper wing plate of the crossbeam 41 is provided with a groove 413 at the hooking area 411. After the lifting hook piece 23 is turned inward, the hooking head 232 falls into the groove 413. The groove 413 can prevent the unhooking phenomenon to a certain extent. In order to make the rotation of the lifting hook piece 23 not be affected, as shown in Figure 2 As shown, a corresponding notch 11 is arranged on the lifting tool beam 1, and the notch 11 is arranged on the rotating track of the lifting hook piece 23, as shown in Figure 3 As shown, the bearing shaft 22 where the lifting hook piece 23 of the utility model is located is located outside the hooking head 232. Therefore, in the hanging state, the hazardous waste disposal box can be self-locked by relying on gravity. Under the action of gravity, the two hooking heads 232 cannot move outward, that is, they cannot be unhooked. The weight of the lifting tool and the hazardous waste disposal box is borne by the bearing shaft 22, and the driving hook assembly 24 does not play a role. That is to say, as long as the hazardous waste disposal box is in a normal lifting state, the breaking point or misoperation of the driving hook assembly 24 will not cause the unhooking of the hazardous waste disposal box. The design can improve the transportation safety of the hazardous waste disposal box.

[0026] As shown in Figure 4 As shown, two color bands 414 are painted on the upper wing plate of the crossbeam 41. The color bands 414 are arranged one by one corresponding to the hooking areas 411. The color bands 414 are made of bright paint, which is convenient for the driver to observe and make the lifting hook tool 2 accurately connect with the hooking area 411. The utility model can be designed and installed with a visual camera for each lifting hook tool 2 to cooperate with the operation of the driver.

[0027] The hooking operation needs to align the lifting appliance to drop, so the operation is more difficult, and the operation level of the crane driver is higher. Since the hazardous waste disposal box is not in the warehouse at this time, it is in the area to be lifted in the landfill, so workers can guide the hooking. After the hazardous waste disposal box is filled in the warehouse, the lifting appliance beam 1 is first completely lowered. With the positioning of the hazardous waste disposal box and the continuous lowering of the lifting appliance beam 1, the hooking head 232 of the hooking piece 23 will first separate from the upper wing plate of the cross beam 41 of the hanging rack 4 (there is a descending movement space of the hooking head 232 between the upper wing plate and the lower wing plate of the cross beam 41). At this time, the driver operates the hooking piece 23 to turn over, so that the hooking head 232 is completely separated from the cross beam 41 of the hanging rack 4. The lifting appliance beam 1 is lifted in the outward turning state of the hooking piece 23, so that the unhooking operation can be smoothly realized. The lifting appliance beam 1 and the hooking tool 2 part (collectively referred to as a lifting appliance) of the utility model can be reused, and each crane only needs to be equipped with a set. The hanging rack 4 of the utility model is installed on the hazardous waste disposal box without disassembly, so a large number of hanging racks 4 need to be made, and each hazardous waste disposal box is equipped with two hanging racks 4.

[0028] The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above-mentioned examples. Any technical solution belonging to the idea of the utility model is within the protection scope of the utility model. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model are also considered as the protection scope of the utility model.
