[0028] The adsorption assembly 4 is mainly used for the hoisting of the front windshield of a tram, and is connected with the bottom plate 14 of the main body frame 1 of the lifting device through the buffer device 5. The adsorption assembly 4 and the buffer device 5 are detachable. The adsorption assembly 4 can be detached or installed according to the hoisting requirements of different components. The adsorption assembly 4 comprises left and right symmetrical suction disc groups, each of which comprises a suction disc bottom plate 44, the two ends of the suction disc bottom plate 44 are connected with arc-shaped connecting rods 41 through connecting rotating shafts 45, and the suction disc bottom plate 44 is uniformly provided with suction discs 42; the suction disc bottom plate 44 on one side of the suction disc group is connected with a mounting plate 43, and the mounting plate 43 is connected with a connecting plate 54. The connecting rotating shaft 45 and the arc-shaped connecting rod 41 are movably connected.

[0029] The buffer device 5 comprises a base connected with the bottom plate 14, the base is provided with a driving motor 51, one end of the driving motor 51 is connected with a driven gear 53 on one side through a driving gear 52, the driven gear 53 is connected with upper and lower lifting assemblies on both sides, and the top of the upper and lower lifting assemblies is connected with the adsorption assembly 4 through the connecting plate 54. When the driving motor 51 works, the driven gear 53 rotates, the upper and lower lifting assemblies work, and the adsorption assembly 4 connected with the connecting plate 54 moves up and down.

[0030] In the embodiment, the upper and lower lifting assemblies comprise driving main rods 56 arranged in the driven gear 53, and a group of driving connecting rods are vertically connected to the two ends of the driving main rod 56 respectively, and the connecting plate 54 is arranged on the top of the driving connecting rod group.

One side of the clamping assembly 3 is connected with an auxiliary fixing frame 6 through an up-down driving assembly, the auxiliary fixing frame 6 is provided with a connecting hole, when a part is placed on the auxiliary fixing frame 6, the part can be bound by passing the rope through the connecting hole. The end of the fixed mounting rod 34 can be threadedly detached, that is, when the connecting hole needs to be entered, the end is unscrewed, after entering the connecting hole, the end is screwed, which can avoid the connection of the rope, and the diameter of the end is greater than the diameter of the connecting hole.

[0032] One end of the hoist body frame 1 is provided with a deceleration turnover motor 15, and the turnover hook claw 11 is connected with the deceleration turnover motor 15 through a shaft. The deceleration turnover motor 15 works to drive the turnover hook claw 11 to open or fold radially along the outer frame of the hoist body frame 1.

The middle part of the support rod 12 is further connected with the hoist body frame through a rotating shaft 121, and when the cylinder 13 works, the vertical standing of the support rod 12 can be completed. In order to save space, the cylinder 13 is laid on the hoist body frame 1.

[0033] In order to better understand the implementation principle of the present application, the following is described through specific application:

[0034] When used as a universal hoist, the hoist in the present application can hoist different parts, and the following describes the use of the hoist in the present application as a bogie hoist and a pantograph hoist:

[0035] Before specific use, the adjustment work of the hoist is carried out, and the electrical elements and pneumatic elements on the hoist are powered through the power source of the crane. The turnover hook claw 11 is adjusted to the position horizontal to the hoist through the deceleration turnover motor 15, and the adsorption assembly 4 is removed. At this time, the fixed mounting rods 34 on both sides of the clamping assembly 3 are in the initial retracted position, and the support rod 12 is in the recovered state. The clamping assembly 3 is in the maximum opening state, that is, the two clamping plates 32 of the clamping assembly are respectively arranged at the two ends of the guide rail assembly, so as to facilitate the subsequent clamping operation.

[0036] When used as a bogie sling, the bogie is heavy, so counterweights are installed at the position of the adsorption assembly 4 to balance the overall weight of the sling. The lifting cylinder 33 works to extend the fixed mounting rod 34, i.e. to make the top end of the fixed mounting rod pass through the connecting hole of the bogie and be fixed at the lower part of the hole, which can be directly bound by a rope or can use a detachable connection mode at the top end of the fixed mounting rod.

[0037] And the bogie is assisted by the clamping assembly 3. During transportation, the main sling directly passes through the auxiliary lifting ring 17 on the four sides of the sling, and then is connected with the main hook of the crane, so that the lifting operation can be directly performed.

[0038] When used as a pantograph sling, the pantograph has different shapes and sizes, so the auxiliary fixing frame 6 of the sling needs to be lowered first to fix the lower part of the pantograph. The upper part is assisted by the clamping assembly 3, and the turning plates 35 on the left and right sides of the clamping assembly 3 are turned to a horizontal angle by the turning mechanism 36, and then the pantograph is fixed by a rope passing through the round holes in the turning plates 35.

[0039] Other boxes such as traction boxes, auxiliary resistance boxes, brake resistance boxes, battery boxes, high-voltage boxes, driver's room air conditioning units, passenger room air conditioning units, etc. can be lifted by the above method. When the turning plates 35 on the left and right sides are turned down, the goods placed on the pallet can also be lifted at the same time, and only the binding between the pallet and the turning plates 35 is needed.

[0040] When the invention is used as a special front windshield glass sling:

[0041] First, install the adsorption assembly 4, and roughly adjust the sling adjustment assembly 2 to determine the number of adjustment supports 22 to be used. In order to cooperate with the subsequent glass turning, the invention is provided with a turning positioning device, which includes a positioning rod 7 and positioning wheels 71 connected to the two ends of the positioning rod 7, and the spacing between the positioning wheels 71 matches the tram track. At the same time, in order to avoid the rolling of the positioning wheels 71, the turning positioning device further includes a stop block 72. Before lifting, the turning positioning device is moved to the corresponding position of the tram head, and the positioning wheels 71 are positioned by the stop block 72.

[0042] The crane is connected with the six lifting rings 25 of the lifting assembly, the two buffer devices 5 adjust the adsorption assembly 4 to the position corresponding to the glass to be installed on site, and then the suction cups 42 on the adsorption assembly work to adsorb the glass. At this time, all the connecting shafts 45 are in a free state, the vacuum suction cups 42 are in contact with the glass, and the glass is fixed on the adsorption assembly by suction force. Since each shaft is in a free state, the adsorption assembly and the glass can be made to conform to each other in shape under the action of the suction force. The clamping assembly 3 is provided with a clamping rubber pad, and the rear end of the glass can be clamped from both ends at the same time.

[0043] Then the glass is lifted to the corresponding position of the overturning positioning device, the slow rotation motor 15 slowly rotates the overturning hook claw 11, the hook at the front end of the overturning hook claw 11 is connected with the positioning rod 7, then three of the six lifting rings are loosened according to the actual situation on site, and the overturning preparation operation is performed. The overturning positioning device can avoid the safety problem caused by the swinging of the lifting assembly during operation.

[0044] When the hook is connected with the positioning rod 7, the remaining three adjusting supports 22 are in a free state, the slow rotation motor 15 continues to drive the overturning hook claw 11 to rotate, the main lifting ring of the crane is connected with the three lifting rings, and the crane operator lifts the main lifting ring of the crane, so that the lifting assembly is in a vertical state through the lifting action of the overturning hook claw 11 and the crane, and the opened supporting rod 12 (that is, the supporting rod 12 is perpendicular to the main body frame of the lifting assembly) is connected with the front hook of the tramcar to play an auxiliary supporting role. When the overall lifting assembly is adjusted to the approximate position of the installed front windshield, the adsorption assembly is fine-tuned through the buffer device 5 to adjust to the correct position of the installed glass. Until the installation of the windshield is completed.

[0045] The driving specific control between the devices in the application belongs to the software part and is not the focus of the protection of the application, so it is not described here.

[0046] In the description of the application, it should be noted that the terms "upper", "lower", "left", "right", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0047] The application has many specific application examples, and the above description is only a preferred embodiment of the application. It should be noted that for ordinary skilled persons in the technical field, some improvements can be made without departing from the principle of the application, and these improvements should also be considered as the protection scope of the application.
