Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in figures 1-3, the utility model provides a liquid chlorine steel bottle lifting device, including cross arm 1, the cross arm is as this device's supporting component. Hoisting device 2 is installed at cross arm 1 top, hoisting device is used for connecting the driving. The hook 3 is hinged to the bottoms of two ends of the cross arm 1, the top of the hook 3 protrudes out of the cross arm 1, the protruding part of the top of the hook is a connecting position, the rotating shaft 4 is rotatably installed in the middle of the cross arm 1, the rotating shaft 4 is fixedly provided with a transmission plate 5, and the transmission plate is parallel to the cross arm. And elastic traction rods 6 are connected between the transmission plate 5 and the hooks 3 on the two sides, two ends of each elastic traction rod 6 are respectively hinged with the connection position at the top of each hook 3 and the transmission plate 5, and a return spring 7 is connected between each transmission plate 5 and the cross arm 1. Under the condition that the hook 3 is not loaded, the two elastic traction rods 6 are not coaxial, so that an included angle of 180 degrees between the transmission plate and the hook traction rod is avoided, the transmission force of the hooks at the two ends pushing the elastic traction rods is offset, and the hooks cannot act. The device has the advantages of simple structure and convenient operation, and can greatly reduce the labor intensity of people and improve the working efficiency.

The bottom of the cross arm 1 is welded with a positioning plate 8, the bottom of the positioning plate 8 is provided with a groove matched with the cross section profile of the steel cylinder, and the groove is used as a guide groove when the device is contacted with the steel cylinder, so that the cross arm can be transversely arranged along the axis direction of the steel cylinder.

Specifically, hoist device 2 includes two connecting blocks 9, two chain sling 10, rings 11, two 9 symmetrical welding of connecting block is at 1 both ends of cross arm, chain sling 10 is connected with connecting block 9 one-to-one, two chain sling 10 all connects on rings 11, rings are as the go-between of driving hoist and mount.

When the lifting appliance is used, the lifting appliance hanging ring is hung on a travelling crane lifting hook, the travelling crane lifting hook is lowered after the position of the travelling crane lifting hook is adjusted to be above a steel cylinder through a travelling crane control switch; the locating plate can automatic positioning, makes hoist automatically regulated direction, and is unanimous with the steel bottle direction. The distance between the 2 hooks is customized according to the length of the liquid chlorine steel cylinder body (the length of the liquid chlorine steel cylinder is 2000, the distance between the endpoints of the lowest ends of the two hooks is 2100, and the distance between the endpoints of the innermost sides is 1900mm), and the two end ring edges of the liquid chlorine steel cylinder can be clamped under the action of the self weight of the lifting appliance; the return spring drives the elastic traction rod and the hook to return in sequence through the transmission plate, clamps the liquid chlorine steel cylinder and then lifts.

When the steel cylinder is unloaded, the crane hook is controlled to move slightly to one side, the hook on one side is stressed to turn outwards, the positioning plate is pushed to rotate by the elastic traction rod, and the hook on the other side is driven to be stressed to turn outwards, so that the steel cylinder can be separated. At the moment, the travelling crane lifting hook is controlled to move upwards, the side hook moves to the upper part of the steel cylinder, and then the travelling crane lifting hook moves in the opposite direction, so that the lifting appliance can finish the operation of detaching the steel cylinder. And controlling the crane hook to move to a new working position to start new hoisting operation.

The elastic traction rod of the device can be bent within a certain range, so that the hook is ensured to drive the positioning plate to rotate.

Furthermore, 2 slings of the device can share one lifting ring and are connected to the cross arms through 2 connecting rods (the length is equal to 700mm of the diameter of the body of the liquid chlorine steel cylinder), so that the 2 cross arms are horizontally parallel and have proper distance, and 2 empty bottles can be hoisted at one time (generally speaking, the empty bottles can be hoisted at one time by 2, and the heavy bottles can be hoisted at one time by 1).
