Description
Technical field
The utility model relates to a kind of lifting apparatus, especially a kind of improvement unload button-type pulley structure.
Background technology
At the Workplace of lifting weight, often use coaster.Coaster has a lot of particular type, but its lifting part is all made up of side shield and pulley, such as a kind of wheeled vehicle disclosed in Chinese utility model patent CN 203180428 U.This structure needs side shield to pull down completely when dismounting steel rope, and complex steps, uses inconvenience, and in hoisting process, the problem swung easily appears in lifting object, brings potential safety hazard.
Utility model content
What the technical problems to be solved in the utility model was to provide a kind of improvement unloads button-type pulley structure, can solve the deficiencies in the prior art, simplify the step of dismounting steel rope, improve the stability of lifting object.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of improvement unload button-type pulley structure, comprise symmetrically arranged first side shield and the second side shield, between first side shield and the second side shield, S. A. is provided with pulley, the top of the first side shield and the second side shield is connected with suspension ring by support, suspension ring are connected with shackle, described first side shield and support are provided with the axle sleeve run through, second side shield is provided with the through hole identical with sleeve diameter, run through in axle sleeve and through hole and be provided with bearing pin, bearing pin is by nut and the first side shield, second side shield and support removably coordinate, axle sleeve is positioned at the second side shield side and is provided with mounting ring, the top of described pulley outer is provided with rubber jacking block, the madial wall close contact of rubber jacking block and the first side shield and the second side shield, and the bottom of pulley is provided with sawtooth portion, and the both sides in sawtooth portion are provided with the metal spring sheet of arc.
As preferably, the bottom of described first side shield and the second side shield is respectively arranged with a limiting stopper, and two limiting stoppers are crisscross arranged, and two limiting stoppers are along with the rotation selective exposure of the second side shield.
As preferably, described pulley is outer is diametrically 3:1 ~ 6:1 with interior ratio diametrically.
The beneficial effect adopting technique scheme to bring is: the top of the first side plate washer and the second side shield adopts the mode of axle sleeve and bearing pin cooperation to be fixed by the utility model, when needs dismounting steel rope, bearing pin is only needed to unload, rotate the angle that the second side shield is certain, the dismounting of steel rope can be carried out, convenient and swift.Rubber jacking block with side shield close contact is set in the outer of pulley, the blessing power of an axis can be applied on the one hand to pulley, avoid the axis play of pulley in rotation process, apply a friction drag can also in addition the rotation of pulley, thus reduce the lengthwise position error of the lifting object caused due to rotator inertia.After steel wire loop is connected on pulley, through metal spring sheet, make metal spring sheet generation elastic deformation, metal spring sheet forms a squeese pressure to the inside for steel rope, makes the position of steel rope bottom pulley keep relatively fixing, decreases the horizontal looseness of steel rope, sawtooth portion can strengthen the static friction force of pulley and steel rope, thus reducing the longitudinal leap of steel rope, this just significantly improves the fastness that steel rope coordinates with pulley, thus improves the stability of lifting object.Limiting stopper can limit the maximum anglec of rotation of the second side shield, improves safety during dismounting.Pulley is diametrically preferably 3:1 ~ 6:1 with interior ratio diametrically outward, both can ensure a good axial support degree and radial dumping force, turn avoid the problem that the excessive installation complexity occurred of pulley is high, propulsive effort demand strengthens.

Detailed description of the invention
The standardized parts used in the utility model all can be commercially, shaped piece all can carry out customized according to specification sheets with the record of accompanying drawing, the concrete connection mode of each part all adopts the conventional means such as bolt, rivet, welding, stickup ripe in prior art, is not described in detail in this.
With reference to Fig. 1-3, the utility model detailed description of the invention comprises symmetrically arranged first side shield 1 and the second side shield 2, between first side shield 1 and the second side shield 2, S. A. 3 is provided with pulley 4, the top of the first side shield 1 and the second side shield 2 is connected with suspension ring 6 by support 5, suspension ring 6 are connected with shackle 7, described first side shield 1 and support 5 are provided with the axle sleeve 10 run through, second side shield 2 is provided with the through hole 12 identical with axle sleeve 10 internal diameter, run through in axle sleeve 10 and through hole 12 and be provided with bearing pin 8, bearing pin 8 is by nut 9 and the first side shield 1, second side shield 2 and support 5 removably coordinate, axle sleeve 10 is positioned at the second side shield 2 side and is provided with mounting ring 11, the top of described pulley 4 outer is provided with rubber jacking block 13, and the madial wall close contact of rubber jacking block 13 and the first side shield 1 and the second side shield 2, the bottom of pulley 4 is provided with sawtooth portion 14, and the both sides in sawtooth portion 14 are provided with the metal spring sheet 15 of arc.The mode that the top of the first side plate washer 1 and the second side shield 2 adopts axle sleeve 10 and bearing pin 8 to coordinate is fixed, when needs dismounting steel rope, only need bearing pin 8 to unload, rotate the angle that the second side shield 2 is certain, the dismounting of steel rope can be carried out, convenient and swift.Rubber jacking block 13 with side shield close contact is set in the outer of pulley 4, the blessing power of an axis can be applied on the one hand to pulley 4, avoid the axis play of pulley 4 in rotation process, apply a friction drag can also in addition the rotation of pulley 4, thus reduce the lengthwise position error of the lifting object caused due to rotator inertia.After steel wire loop is connected on pulley 4, through metal spring sheet 15, make metal spring sheet 15 that elastic deformation occur, metal spring sheet 15 forms a squeese pressure to the inside for steel rope, makes the position of steel rope bottom pulley keep relatively fixing, decreases the horizontal looseness of steel rope, sawtooth portion 14 can strengthen the static friction force of pulley 4 and steel rope, thus reducing the longitudinal leap of steel rope, this just significantly improves the fastness that steel rope coordinates with pulley 4, thus improves the stability of lifting object.The bottom of the first side shield 1 and the second side shield 2 is respectively arranged with a limiting stopper 16, two limiting stoppers 16 are crisscross arranged, two limiting stoppers 16 are along with the rotation selective exposure of the second side shield 2, limiting stopper 16 can limit the maximum anglec of rotation of the second side shield 2, improves safety during dismounting.Pulley 4 is outer is diametrically 7:2 with interior ratio diametrically.
In addition, the part be connected with support 5 at suspension ring 6 is provided with rubber bottom plate 17, is provided with the rubber top board 18 contacted with rubber bottom plate 17, the contact surface of rubber bottom plate 17 and rubber top board 18 is provided with rough layer 19 in the inner side at support 5 top.When coaster lifting weight, the gravity of weight applies with rubber top board 18 with on rubber bottom plate 17, the amount of a making rough layer 19 extrudes mutually, mutual static friction force improves rapidly, can avoid relatively rotating of in hoisting process suspension ring and support, ensure the stability of hoisting process, when for lifting weight, rubber top board 18 with rubber bottom plate 17 because static friction force reduces, can flexible rotating, thus realize the adjustment lifting angle.
