Description

Flexible hoisting tool for large brake products

Technical Field

The utility model relates to a flexible lifting device for large brake products, which belongs to a lifting device.

Background

As is well known, when the electric hoist bridge crane hoists large-scale brake accessories, the workpiece can only be vertically translated through the lifting hook, and the workpiece cannot be turned and inverted, so that the large-scale workpiece is time-consuming and labor-consuming in turnover between working procedures or working steps, and is very easy to collide with.

The large-scale brake product produced by our company is a disc brake friction coupling, called a brake disc for short. When the brake disc is machined, only the lathe worker process needs to repeat the processes of lifting by the lifting hook, falling to the ground, unloading the lifting hook to turn over and then loading the lifting hook to lift three times by using the electric hoist, the workpiece is easy to collide during the process, and the machining working hours and the labor intensity of workers are increased.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a flexible lifting device of large-scale braking product, this lifting device makes can freely overturn after the brake disc is hoisted by electric block, need not secondary hoist and mount to reduce colliding with of part, reduce the hoist and mount time, alleviate workman intensity of labour.

For solving the above problems, the specific technical scheme of the utility model is as follows: the utility model provides a flexible lifting device of large-scale braking product, is articulated through the bolt at the middle part of two jib that cross arrangement, at the bottom fixed connection lifting socket assembly of every jib, is equipped with free rotation's lifting hook in the lifting socket assembly, and during operation, two lifting hooks insert the side opening of braking product jointly.

The lifting seat assembly is structurally characterized in that bearings are respectively arranged on two sides of an inner cavity of a lifting seat body, an outer ring of each bearing is in interference fit with the inner wall of the lifting seat body, and an inner ring of each bearing is coaxially matched with a lifting hook; the front end of the hanging seat body is connected with a hanging seat front cover through a screw, and the axial displacement of the hanging hook is limited; the rear end of the hanging seat body is connected with a hanging seat rear cover through a screw, and the hanging seat rear cover is connected with the hanging rod.

The hanger rod is made of angle steel, and a bending angle is arranged at the joint of the hanger rod and the rear cover of the hanging seat; the top of the suspender is connected with a steel wire rope.

The part of the lifting hook extending out of the front cover of the lifting seat is rectangular, the width of the part is larger than the diameter matched with the bearing, and the extending section corresponds to the shape of a side hole of a large automatic product; the front cover of the hanging seat is provided with an opening groove with the width consistent with the diameter of the corresponding position of the hanging hook, and the front cover of the hanging seat passes through the hanging hook through the opening groove and is connected with the hanging seat body.

The flexible hoisting tool for large brake products adopts a structure of the lifting hook and the lifting seat assembly, and realizes the function of free rotation after being positioned by the two lifting hooks, so that the lifting of the lifting hook is not required to be carried out again after the lifting hook is landed, the lifting hook is unloaded to turn over, and the lifting hook is assembled again, the collision of workpieces is obviously reduced, the hoisting time is reduced, and the labor intensity of workers is reduced.

Detailed Description

As shown in figures 1 to 3, the middle parts of two suspension rods 8 which are arranged in a crossed mode are hinged through bolts 9, a suspension seat assembly is fixedly connected to the bottom of each suspension rod 8, a free-rotating lifting hook 1 is arranged in the suspension seat assembly, and during operation, the two lifting hooks 1 are jointly inserted into a side hole of a braking product.

The hanging seat assembly is structurally characterized in that bearings 4 are respectively arranged on two sides of an inner cavity of the hanging seat body 3, an outer ring of each bearing 4 is in interference fit with the inner wall of the hanging seat body 3, and an inner ring of each bearing 4 is coaxially matched with the hook 1; the front end of the hanging seat body 3 is connected with the hanging seat front cover 2 through a screw, and the axial displacement of the hanging hook 1 is limited; the rear end of the hanging seat body 3 is connected with a hanging seat rear cover 5 through a screw, and the hanging seat rear cover 5 is connected with a hanging rod 8. The structure can realize free rotation of the lifting hook.

The hanger rod 8 is made of angle steel, and a bending angle is arranged at the joint of the hanger rod and the rear cover 5 of the hanging seat; a steel wire rope 10 is connected to the top of the suspension rod 8. When the brake device works, the steel wire rope 10 is pulled upwards, the bottom of the suspender 8 is inwardly closed under the action of the steel wire rope 10, the lifting hook is inserted into a side hole of a large brake product to clamp the product, and the product can be turned over in the lifting process.

The part of the lifting hook 1 extending out of the front cover 2 of the lifting seat is rectangular, the width of the part is larger than the diameter matched with the bearing 4, and the extending section corresponds to the shape of a side hole of a large automatic product, so that the clamping is convenient; the width of the opening groove is consistent with the diameter of the corresponding position of the lifting hook on the lifting seat front cover 2, the lifting seat front cover 2 penetrates through the lifting hook 1 through the opening groove and is connected with the lifting seat body 3, and the lifting seat front cover 2 can directly utilize the opening groove to directly avoid the lifting hook 1 and is connected with the lifting seat body 3.

During operation, the rectangular structure parts at the front ends of the two special lifting hooks are inserted into the gaps of the cooling fins of the brake disc, then the steel wire rope 10 is lifted by the electric hoist lifting hooks, after the steel wire rope 10 drives the upper parts of the two lifting rods 8 to be stressed, the working ends at the lower parts of the lifting rods are stressed and clamped tightly, the brake disc is lifted by the special lifting hooks 1, after the brake disc is moved for a proper distance, the brake disc is manually turned over, the surface to be processed is turned outwards, and the electric hoist is moved again to move the brake disc to a specified. When the lifting hook is disassembled, only the lifting hook of the electric hoist is needed to be lowered, the upper tension of the lifting rod is relieved at the moment, the lower clamping force of the lifting rod disappears, the special lifting hook 1 can be easily pulled out, the lifting tool is disassembled, and the brake disc realizes the process of turnover.

What has been described above is merely a preferred embodiment of the invention. It should be noted that variations and modifications can be made by those skilled in the art without departing from the principle of the present invention, and they should also be considered as falling within the scope of the present invention.
