In mechanical hoisting equipment, a hydraulic hoist is controlled by electricity and liquid, so that the hydraulic hoist is stable in lifting, flexible in operation, free of clamping stagnation and wide in bearing range, is deeply favored by people, and has wider and wider application fields.

The bearing mounting seat used in the market at present is mainly in a split type, namely, the bearing mounting seat is divided into a chain mounting seat and a chain wheel seat, the chain mounting seat is sleeved in the chain wheel seat, two castings need to be provided with two sets of dies, the processing amount is increased, the requirement for matching size is increased, the whole size is large, the structure is relatively complex, and the dead weight is heavy. And the foundry goods material on the existing market is QT spare, and intensity is restricted in work, can't satisfy the use of some operating modes, causes the cracked risk of chain mount pad even.

Disclosure of Invention

An object of the utility model is to provide a hydraulic block bears device to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a hydraulic block bears device, is including bearing the mount pad, bearing chain axle, stop collar and chain, it casts out with cast steel material to bear the mount pad, is integral, both undertakes the effect with external connection's sprocket seat, and the effect of chain mount pad is used as the chain operation again to inside cavity, it bears chain axle to bear mount pad internally mounted, bear the one end of chain axle and install first bearing, the inside sealing member that is provided with of mount pad that bears of first bearing one side, bear the other end of chain axle and install the second bearing, the stop collar is installed to the one end that bears the mount pad.

Further, the structure of the bearing mounting seat is a cast steel integral structure.

Further, the material of the bearing mounting seat is cast steel.

Further, the inner cavity of the bearing mounting seat is provided with a through cavity.

Further, an outer groove is formed in the outer side of the bearing chain shaft.

Furthermore, the outer connecting end of the bearing chain shaft is provided with a spline.

Further, the bearing chain shaft is coupled with the chain through a clamping groove type structure.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model structurally designs the integral bearing mounting seat by directly installing the bearing chain shaft inside the bearing mounting seat, saves a set of dies, and only needs to design the outer groove of the passing chain in the cavity, thereby realizing that the bearing mounting seat not only serves as a carrier of an external link, but also serves as a through cavity of the chain, the whole structure is compact, the volume is reduced, the structure is relatively simple, and the dead weight is lightened;

2. the QT material bearing the mounting seat is changed into cast steel, so that the material texture compactness is improved, the use strength is greatly improved, the possibility of breakage of the mounting seat is reduced, and the safety coefficient of the hydraulic hoist is greatly improved;

3. the spline of the bearing chain shaft rotates under the action of the power device, so that the chain is driven to move in the bearing mounting seat, and the lifting effect of a heavy object is realized.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a hydraulic block bears device, is including bearing mount pad 1, bearing chain axle 2, stop collar 6 and chain 7, bears 1 internally mounted of mount pad and bears chain axle 2, bears the one end of chain axle 2 and installs first bearing 3, and the bearing mount pad 1 inside of 3 one sides of first bearing is provided with sealing member 4, bears the other end of chain axle 2 and installs second bearing 5, and stop collar 6 is installed to the one end of bearing mount pad 1.

Further, the structure of the bearing mounting seat 1 is a cast steel integral structure;

further, the material of the bearing mounting seat 1 is cast steel;

further, the inner cavity of the bearing mounting seat 1 is provided with a through cavity.

Further, the outer connecting end of the bearing chain shaft 2 is provided with a spline.

Further, the bearing chain shaft 2 is coupled with the chain 7 through a slot type structure.

The working principle is as follows: the external system starts to drive the spline bearing the chain shaft 2 to rotate, so that the chain 7 is driven to move in the chain running groove bearing the mounting seat 1, the lifting effect of the heavy object is realized, the external system stops, the bearing chain shaft 2 stops rotating, the chain 7 also stops, and the heavy object is not moved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
