Abstract
The invention discloses a connecting assembly of a lifting machine. The connecting assembly of the lifting machine comprises a connecting shaft and a connecting sleeve, wherein a mounting part is arranged on the connecting shaft; the connecting sleeve comprises a sleeve hole matched with the connecting shaft, wherein the sleeve hole comprises a guide part. Through setting the connecting assembly of the lifting machine formed by matching the connecting shaft and the connecting sleeve, the structure is simple and the production cost of the lifting machine can be effectively reduced.
Description
Technical field
The invention belongs to field of mechanical technique, the lift that is specifically related to a kind of lift connection part and uses this lift connection part.
Background technique
Lift is carrying people or goods go up and down on passage vertically the platform or the elevating mechanism equipment or the device of semiclosed platform.Be by platform and handle the integral body that equipment, motor, cable and other supplementary equipment of their usefulness constitute.
The development of lift is being in a peak state, because most of producers or individual have more selected multi-storey building in order to improve the utilization ratio in place, also needs a kind of device to come the convenient decline goods that promotes up and down thus.Because common elevator cost is high, bearing capacity is lower, is not suitable for loading tens tons of perhaps goods of hundreds of ton, comes supplement production and freight transportation so developed the hydraulic lift of high-bearing capacity.Hydraulic lifting Cargo Lift i.e. safety has the load capacity of super large again, and easy to maintenance, makes the faster development that this special industry has.
Lift can be divided into according to the difference of structure: fork type elevator, double-cylinder type lift, aluminum alloy (column) formula lift, crank arm type lift (update of folding-jib), guide rail chain type lift (elevator, Cargo Lift), cable type hydraulic lifting apparatus.
But no matter which kind of lift wherein all need be used a large amount of connection parts, and the most complex structure of lift connection part of existing technology, and cost of production is higher, is unfavorable for the control of cost of production.
Summary of the invention
The object of the present invention is to provide a kind of lift connection part simple in structure.
The present invention also aims to provide a kind of lift.
Be one of realization foregoing invention purpose, a kind of lift connection part provided by the invention, this lift connection part comprises:
Coupling shaft, said coupling shaft is provided with assembly department;
Connecting sleeve, said connecting sleeve includes trepanning, is used for cooperating with said coupling shaft;
Wherein, include guide portion on the said trepanning.
As further improvement of the present invention, include slug hole on the said assembly department.
As further improvement of the present invention, comprise the hold-down apertures that runs through it on the said connecting sleeve.
As further improvement of the present invention, the diameter of said hold-down apertures is 5 millimeters.
As further improvement of the present invention, said coupling shaft is through quenching with Subsequent tempering.
As further improvement of the present invention, said connecting sleeve is through quenching with Subsequent tempering.
For realizing above-mentioned another goal of the invention, the present invention provides a kind of lift, and said lift comprises aforesaid lift connection part.
Compared with prior art, the present invention cooperates the lifting axis connection part of forming through being provided with by coupling shaft and connecting sleeve, and it is simple in structure, can effectively reduce the cost of production of lift.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of coupling shaft in the lift connection part of the present invention;
Fig. 2 is the structural representation of connecting sleeve in the lift connection part of the present invention.
Embodiment
Below will combine embodiment shown in the drawings to describe the present invention.But these mode of executions do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these mode of executions, method or the function all is included in protection scope of the present invention.
Cooperation sees figures.1.and.2, and introduces an embodiment of lift connection part of the present invention, and in this mode of execution, this lift connection part comprises coupling shaft 10 and connecting sleeve 20.
Include trepanning 21 on the connecting sleeve 20, coupling shaft 10 matches with connecting sleeve 20 through this trepanning 21.And, as preferred embodiment, including guide portion 22 on the trepanning 21, the diameter of this guide portion 22 is greater than the diameter of trepanning 21, and so, coupling shaft 10 can make things convenient for exactly and cooperates with trepanning 21.Certainly, in other embodiments, also this guide portion 22 can be set, this kind changes bad mode of execution and must work as and belong within protection scope of the present invention.
As preferred embodiment, also include the hold-down apertures 23 that runs through it on the connecting sleeve 20, can cooperate by extraneous compacting part the relative position relation of fixed connection shaft 10 and coupling shaft 10 through this hold-down apertures 23.
Distinguishingly, the diameter of hold-down apertures 23 is 5 millimeters.
Distinguishingly, coupling shaft 10 is through quenching with Subsequent tempering.
Distinguishingly, connecting sleeve 20 is through quenching with Subsequent tempering.
So, coupling shaft 10 and the connecting sleeve 20 through quenching with Subsequent tempering can guarantee intensity preferably, the working life of prolongation lift connection part.
The lift of employing lift connection part provided by the invention can be controlled cost effectively.
The present invention has following beneficial effect through above-mentioned mode of execution: cooperate the lifting axis connection part of forming through being provided with by coupling shaft and connecting sleeve, it is simple in structure, can effectively reduce the cost of production of lift.
Be to be understood that; Though this specification is described according to mode of execution; But be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technological scheme in each mode of execution also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
