Description

Middle cross-shaped hinge meter hole arc door hydraulic hoist embedded part structure

Technical Field

The utility model relates to a hydraulic hoist technical field especially relates to a middle cross hinge table hole radial gate hydraulic hoist buries a structure.

Background

The surface hole arc door hydraulic hoist with the cross hinge in the middle has a complex embedded part structure, and a rotating body and a hinge support seat need to rotate. As shown in fig. 3 and 4, in the conventional connection mode, a bush and a self-lubricating shaft sleeve are added between a rotating body and a hinge base, the bush and the rotating body are fixed together in a shrink fit mode, and when the device works, the bush and the rotating body are kept still, and the bush and the self-lubricating shaft sleeve rotate.

This conventional approach presents several difficulties in the production process:

1. the size of the embedded part is large, the inner diameter of the bushing can often reach phi 800mm or even larger, the wall thickness needs to be about 35mm to ensure the strength, and meanwhile, the material of the bushing is made of stainless steel, so that the cost of raw materials is high;

2. meanwhile, after the stainless steel bushing is machined and formed, the stainless steel bushing is easy to deform due to a large inner diameter, and the stainless steel bushing is deformed after being machined frequently on a lathe, so that subsequent assembly work is extremely difficult to perform;

3. the bushing needs to be assembled in a hot sleeve mode, the outer cylinder of the rotating body needs to be processed, namely, a step is processed on the outer cylinder of the rotating body for assembling the bushing, so that the processing amount is extremely large, and time and labor are wasted;

4. since it is necessary to machine a stepped surface of the outer cylinder of the rotating body, that is, to thin the thickness of the rotating body at the mounting position, the strength of the outer cylinder of the rotating body is weakened.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to overcome the not enough of prior art, the utility model provides a can effectively alleviate raw and other materials cost and work load, effectively guarantee part intensity and bulk strength, the better middle cross hinge table hole radial gate hydraulic hoist of atress buries a structure.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an intermediate cross hinge table hole radial gate hydraulic hoist buries a structure, includes rotator and hinge seat, hinge seat inner wall on be fixed with the self-lubricating axle sleeve, the urceolus of rotator on then correspond self-lubricating axle sleeve position build-up welding and have the stainless steel layer, the outer peripheral face and the contact of self-lubricating axle sleeve inner wall on stainless steel layer.

In the above scheme, with the normal running fit of original bush and self-lubricating axle sleeve, the improved design is the cooperation of the stainless steel layer of build-up welding and self-lubricating axle sleeve, need not to process the step on the urceolus of rotator, can not weaken rotator intensity, and the stainless steel layer of build-up welding combines as an organic wholely with the rotator urceolus simultaneously, and the zero clearance can not take place deformation, and whole atress is good and build-up welding thickness can reduce, effectively reduces raw and other materials cost.

Preferably, the thickness of the stainless steel layer is 10 mm.

Preferably, the stainless steel layer be greater than the axial length of self-lubricating axle sleeve along the axial length of rotator, stainless steel layer front end and self-lubricating axle sleeve front end parallel and level, rear end then grow out in self-lubricating axle sleeve rear end.

The beneficial effects of the utility model are that, the utility model discloses a middle cross hinge table hole radial gate hydraulic hoist buries a structure, and structural design is reasonable, adopts the mode of build-up welding to connect stainless steel layer and rotator, becomes whole between the two, does not have the clearance, and bulk strength is high, the atress is good, can effectively reduce stainless steel layer thickness simultaneously, reduces raw and other materials cost and processingquantity under the prerequisite of guaranteeing part intensity.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The middle cross-shaped hinge table hole arc door hydraulic hoist embedded part structure shown in fig. 1 and fig. 2 is the best embodiment of the utility model, which comprises a rotator 2 and a support hinge seat 1. The bearing and hinging seat is characterized in that a self-lubricating shaft sleeve 4 is fixed on the inner wall of the bearing and hinging seat 1, a stainless steel layer 3 is arranged on the outer barrel of the rotator 2 in a surfacing mode corresponding to the self-lubricating shaft sleeve 4, and the surfacing thickness of the stainless steel layer 3 is designed to be about 10 mm. The peripheral surface of the stainless steel layer 3 is contacted with the inner wall of the self-lubricating shaft sleeve 4. Stainless steel layer 3 along 2 axial length of rotator be greater than self-lubricating axle sleeve 4's axial length, 3 front ends on stainless steel layer and self-lubricating axle sleeve 4 front end parallel and level, rear end then grow out in self-lubricating axle sleeve 4 rear end.

The middle cross hinge table hole radial gate hydraulic hoist that above-mentioned scheme provided buries a structure, with original bush 5 and self-lubricating axle sleeve 4's normal running fit, the improved design is stainless steel layer 3 and self-lubricating axle sleeve 4's cooperation of build-up welding, and structural design is reasonable, for traditional connected mode, has following advantage:

1. by adopting a surfacing mode, no gap exists between the stainless steel layer 3 and the base material of the rotating body 2, the stainless steel layer and the base material are integrated into a whole, and the whole stress is better;

2. the mode of overlaying is adopted, an annular bushing 5 does not need to be machined, the problem of part strength does not exist, only the thickness of a single side of about 10mm can be overlaid during overlaying, compared with the thickness of the single side of about 35mm when the bushing 5 is manufactured, the thickness is greatly reduced, the cost of raw materials is greatly reduced, and the condition that the bushing 5 deforms after being machined in the traditional mode can not occur;

3. because the surfacing welding is carried out without carrying out the hot sleeve, the outer cylinder of the rotating body 2 does not need to be processed with steps required during the hot sleeve assembling, only a small section of processing surface required during the surfacing welding is needed, and the processing amount is greatly reduced;

4. because the outer cylinder of the rotating body 2 does not need to be processed with steps, the weakening of the strength of the outer cylinder of the rotating body 2 does not exist, the integral strength is stronger, and the stress is better.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
