Mountain, agricultural, electric power, building production and construction, harbour, dock, warehouse machine installation, goods lifting etc..
When carrying out hanging operation, it is ensured that the connective stability of suspension hook and hanging object, existing lifting block cost is higher, behaviour
It is inconvenient to make, and causes the phenomenon that suspension hook and hanging object come off occur to happen occasionally, and when there is damage parts to need to change, dismounting
It is not easy.
The content of the invention
It is an object of the invention to provide a kind of lifting block simple in construction, easy to operate, can firmly with hanging
Thing connects, and ensures stability.
The technical scheme is that：A kind of lifting block, including mounting bracket, pulley bearings, spacer, bearing pin, fastening
Nut, U-shaped button, suspension hook and steel wire rope；
The mounting bracket has two pieces, is divided into mounting bracket and lower mounting bracket, and mounting bracket includes mounting bracket body and reinforcing plate,
Reinforcing plate is with mounting bracket body by being welded as a whole；The mounting bracket body is provided with tapped through hole, upper mounting bracket and lower installation
Frame is realized by the cooperation of bolt, plain cushion I, spring washer I and nut and is fastenedly connected；The reinforcing plate is provided with what is coordinated with bearing pin
Axis hole；The bearing pin connects pulley bearings and spacer, cooperation and bearing of the clamp nut by plain cushion II and spring washer II respectively
Pin has the connection of screw thread one end；The pulley bearings and spacer are located at the same side of reinforcing plate, and clamp nut is located at reinforcing plate
Another side, spacer are in the centre of pulley bearings and clamp nut；It is described it is U-shaped deduction of points not Lian Jie mounting bracket and suspension hook, suspension hook
Connecting steel wire ropes, the length of steel wire rope is depending on the standard knot of different model.
Preferably, the mounting bracket body of the mounting bracket is at least provided with two tapped through holes, for upper mounting bracket and lower peace
The bolt connection shelved.
Preferably, the bearing pin has screw thread one end to be provided with cotter-pin hold, and split pin may pass through cotter-pin hold, prevent from fastening
Nut rotation comes off or slided.
Preferably, the clamp nut is hexagon slotted nut.
Preferably, the reinforcing plate angle in the upper mounting bracket and lower mounting bracket is 15~30 degree.
The beneficial effects of the invention are as follows：Lifting block of the invention is simple in construction, easy to use, production cost is low, carrying
Ability is strong, can ensure the stability that suspension hook is connected with hanging object, safe, and convenient dismounting, beneficial to maintenance.

Embodiment
Below in conjunction with the implementation structure of the accompanying drawing description present invention.
As shown in Figures 1 to 4, lifting block of the present invention includes mounting bracket 1, pulley bearings 6, spacer 7, bearing pin 8, fastening
Nut 12, U-shaped button 14, suspension hook 15 and steel wire rope 16；
Mounting bracket 1 has two pieces, is divided into mounting bracket and lower mounting bracket, and mounting bracket 1 includes mounting bracket body and reinforcing plate 11,
Reinforcing plate 11 is with mounting bracket body by being welded as a whole；Mounting bracket body is provided with tapped through hole, upper mounting bracket and lower mounting bracket
Realized and be fastenedly connected by the cooperation of bolt 2, plain cushion I 3, spring washer I 4 and nut 5；Reinforcing plate 11 is provided with to be coordinated with bearing pin 7
Axis hole；Bearing pin 8 connects pulley bearings 6 and spacer 7, the cooperation that clamp nut 12 passes through plain cushion II 9 and spring washer II 10 respectively
There is screw thread one end to be connected with bearing pin 8；Pulley bearings 6 and spacer 7 are located at the same side of reinforcing plate 11, and clamp nut 12 is located at
Another side of reinforcing plate 11, spacer 7 are in the centre of pulley bearings 6 and clamp nut 12；U-shaped button 14 connects mounting bracket respectively
1 and suspension hook 15, the connecting steel wire ropes 16 of suspension hook 15, the length of steel wire rope 16 is depending on the standard knot of different model.
Wherein, the effect of spacer 7 is tight therefore nut is compressed the power of bearing inner race than more uniform, protect pulley bearings not by
Damage.
Preferably, bearing pin 8 has screw thread one end to be provided with cotter-pin hold 81, and split pin 13 may pass through cotter-pin hold 81, prevent
