[0029] Next, through specific embodiments, the technical solutions of the present utility model will be further described in detail.

[0030] As Figures 1 - 5 shown, a special hoist for transferring train tanks includes an upper crossbeam 1, a slewing mechanism 3, a lower crossbeam 2, an opening and closing mechanism 4, a tank lifting arm 5 and a car hood lifting assembly 6.

[0031] A suspension structure is provided at the upper end of the upper crossbeam 1 for connecting the lifting equipment. In this embodiment, four fixed pulleys 11 are installed at the four corners of the upper crossbeam 1.

[0032] The lower crossbeam 2 is installed on the upper crossbeam 1 through the slewing mechanism 3 so that the lower crossbeam 2 can make a slewing motion around the slewing mechanism 3. The slewing mechanism 3 can be driven by a motor and an encoder is installed to control the slewing angle. The lower crossbeam is a frame beam with a crossbeam and a vertical beam to provide stable support.

[0033] The opening and closing mechanism 4 is installed on the lower crossbeam 2. The opening and closing mechanism 4 is used to drive the opening and closing of the tank lifting arm 5. A hook 51 is provided at the clamping end of the tank lifting arm 5 corresponding to the tank.

[0034] In this embodiment, the tank lifting arm 5 includes two sets of swing arms arranged oppositely. The tops of the two sets of swing arms are both hinged to the lower crossbeam, and hooks 51 matching the tank lugs are provided at the lower parts of the two sets of swing arms.

[0035] There are various design forms of the opening and closing mechanism 4. For example, the two sets of swing arms are driven to rotate around the hinge point by the way of a motor cooperating with a gear train, or by using an electric push rod or a cylinder. The tail end of the electric push rod or the cylinder is installed on the lower crossbeam, and the movable end is hinged to the swing arm through a scissor mechanism, a connecting rod mechanism or directly, so as to drive the swing arm to rotate around the hinge point.

[0036] The movement mode of the opening and closing mechanism 4 cooperating with the tank lifting arm 5 is the hoisting mode of a traditional tank, that is, a clamping structure. In order to fit the shape of the tank, in this embodiment, the inner end contour shape of the swing arm is a circular arc fitting the tank.

[0037] The car hood lifting assembly 6 is installed at the bottom end of the tank lifting arm through a detachable structure. In this embodiment, a lifting lug 61 is provided at the top end of the bracket of the car hood lifting assembly 6 corresponding to the hook 51 of the swing arm, and the lifting lug 61 cooperates with the hook 51 to form the detachable structure. In a preferred embodiment, for further ensuring safety, a locking bolt or other structure can also be provided for the hook 51 and the lifting lug 61.

[0038] The car hood lifting assembly 6 includes a bracket 62 and a plurality of electromagnets 63 distributed on the bracket 62. The adsorption surfaces of the plurality of electromagnets 63 cooperate to form a connection surface for lifting the car hood, and the adsorption surfaces are all arranged downward. Since the contour of the carriage top cover is a slightly arc-shaped surface, therefore, the car hood lifting assembly 6 is designed according to the contour shape of the arc-shaped surface. Specifically, the bracket 62 is a frame beam with transverse ribs, and the lifting lug 61 is arranged on the transverse ribs; at least two rows of electromagnets 63 are installed at the bottom end of the bracket 62, and each row of electromagnets 63 is arranged along the length direction of the bracket 62, and the shape formed by the adsorption surfaces of the plurality of electromagnets is arc-shaped.

[0039] To facilitate the power supply of the electromagnets, an electric control box 7 and a power supply circuit are provided on the upper cross beam 1. The power supply circuit is led to the lower cross beam or the tank lifting arm and a socket is provided. A plug is correspondingly provided on the car hood lifting assembly. After the car hood lifting assembly 6 is assembled, the plug needs to be inserted into the socket to obtain power.

[0040] Description of the working process:

[0041] During use, first hang the car hood lifting assembly 6 on the hook 51 of the tank lifting arm 5 through four lifting lugs 61, and add bolts if necessary to ensure safety. Then, the worker connects the plug and the socket to supply power to the electromagnets.

[0042] After the train arrives, the car hood is adsorbed by the electromagnets of the car hood lifting assembly 6, and then the car hood is lifted and placed at the designated position. After all the car hoods are unloaded, the plug of the car hood lifting assembly 6 is pulled out, and the whole is unloaded from the tank lifting arm 5.

[0043] Then control the tank lifting arm 5 to move to a suitable position directly above the carriage. The tank lifting arm 5 moves downward, and the tanks are lifted one by one by the clamping method. If the placement direction of the tanks is not correct, the direction is adjusted by controlling the slewing mechanism to make the tank lifting arm 5 adapt to it, and then the lifting is carried out.

[0044] After all are completed, check whether it is still necessary to load the tanks. Finally, after determining that the lifting work of the tanks is completed, reassemble the car hood lifting assembly 6 and lift and install the carriage top covers one by one, and the whole operation is completed.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
