Description
Technical field
The invention belongs to technical field of hoisting facility, be specifically related to a kind of Shockproof wheel substructure that is applicable to the Horizontal jack trailing wheel, is the improvement to the rear-wheel structure of existing Horizontal jack.
Background technology
At present, the rear-wheel structure that is applied to Horizontal jack is disclosed by Fig. 1, it comprises bolt 1, wheel stand 2, ball bearing of main shaft 3, wheel carrier 4, pin 5, lining 6 and wheel body 7, the described stand 2 of taking turns directly is formed on the jack pedestal, described bolt 1 is rear with bullet pad 12 and nut 11 lockings through wheel carrier 4 and wheel stand 2, thereby described wheel carrier 4 is arranged on to described the wheel on stand 2, described ball bearing of main shaft 3 be placed in wheel carrier 4 and and the wheel stand 2 between, make described wheel carrier 4 do any rotation of 360 ° of scopes with respect to wheel stand 2, described lining 6 is arranged in the central shaft hole of wheel body 7, axial centre at lining 6 offers manhole, described wheel body 7 is placed in a pair of of wheel carrier 4 and takes turns between arm, described pin 5 is cylindrical pin, this pin 5 after the manhole of taking turns through wheel carrier 4 a pair of in the middle of circular pin hole corresponding on arm and lining 6 by described wheel body 7 pivotal joints on described wheel carrier 4.Above-mentioned rear-wheel structure, there will be unavoidably the phenomenon that is uneven in the assembling process of jack, particularly jack is used and can produce certain permanent deformation later in long-term load-carrying, can cause equally the rugged phenomenon of four-wheel, once, if produce the uneven phenomenon of four-wheel, jack is in pushing mobile process, the impulsive force that relatively gives ground also can increase, not only easily damage ground, and can cause larger noise.
For above-mentioned existing problems, Chinese invention patent Granted publication CN101028914B discloses a kind of name and has been called " the jack wheel installing structure with shock absorbing apparatus ", its formation mainly comprises a support, a d-axis, a Compress Spring and an axle sleeve, this axle sleeve is to be fixed in advance on the trailing wheel top cover of jack, Compress Spring is inserted in after d-axis to replant into axle sleeve and form and fastens location, and d-axis and support are fixing.By the compression variation of spring, make trailing wheel contact with ground all the time, thereby guaranteed that the jack four-wheel remains the state of landing.But this jack wheel installing structure needs traditional wheel installing structure is transformed when mounted, and d-axis and axle sleeve all adopt welding process and described support with trailing wheel top cover structure for being fixedly connected with, thereby lack supporting alerting ability, after completing, welding also needs wheel is sprayed paint again, troublesome poeration can not be transformed existing product immediately.
In view of above-mentioned prior art, be necessary the rear-wheel structure of existing Horizontal jack is improved, for this reason, the applicant has done useful design, and technical scheme described below produces under this background.
Summary of the invention
Task of the present invention is the Shockproof wheel substructure that a kind of jack will be provided, be particularly suitable for being arranged on the trailing wheel position of Horizontal jack, it can not change the profile structure of conventional wheel, without again wheel installing structure being welded and lacquer spraying technique, by directly conventional wheel being replaced as to this wheel, can use, and Assembly &Disassembly is flexible, convenient, there is good shock-proof effect simultaneously, no matter when unloaded or heavily loaded, the four wheels that all can guarantee jack remains the state of landing, therefore in jack passing process, can reduce impact and destruction that wheel causes ground, and reduction noise.
Task of the present invention completes like this, a kind of Shockproof wheel substructure of jack, comprise bolt, the wheel stand, ball bearing of main shaft, wheel carrier, pin, lining and wheel body, describedly take turns the rear side that stand is connected in the jack pedestal, described wheel carrier has a chassis and is formed in a pair of arm of taking turns on chassis with the extension corresponded to each other, take turns position corresponding on arm and offer respectively pin hole a pair of, described bolt is used bullet pad and nut locking after the chassis through on wheel carrier and wheel stand, described ball bearing of main shaft consists of ball retainer and many pieces of steel balls that are located on ball retainer, this ball bearing of main shaft is placed between wheel carrier and wheel stand, described lining is arranged in the central shaft hole of wheel body, described wheel body is placed in a pair of of wheel carrier and takes turns between arm, be characterized in: the axial centre at lining offers an elongated hole, the cross sectional shape of described pin is non-circular, pin be serially connected in elongated hole in the middle of lining with in a pair of pin hole and with a pair of arm structure of taking turns for being fixedly connected with, described lining also is equipped with a locating dowel pin on a side opening wall of elongated hole, be arranged with a Compress Spring on described locating dowel pin, one end of described Compress Spring is conflicted on described pin, the other end of Compress Spring is conflicted on described lining.
In a specific embodiment of the present invention, the cross sectional shape of the wherein at least one pin hole in a pair of pin hole is polygon.
In another specific embodiment of the present invention, described polygon is square.
In another specific embodiment of the present invention, the cross sectional shape of described pin is square.
The present invention is due to after adopting said structure, by the adjustment compression degree of bush inside Compress Spring self-adapting type, can make the four-wheel of jack remain the state of landing, therefore can reduce the impact of jack wheel to ground, there is good shock-proof effect, and reduced noise; Because the wheel contour structures on this wheel contour structures and traditional jack is identical, therefore, change this Shockproof wheel substructure on traditional jack after, can realize same technique effect, there is good commonality, enlarged Applicable scope; The Assembly &Disassembly of wheel more flexibly, conveniently.
