Abstract

The invention discloses a mobile equipment supporting and retracting device, which is particularly suitable for supporting and fixing middle-size and small-size mobile equipment after getting to a work field in the field and is mainly and technologically characterized by comprising a pedestal 1, an inner sleeve 2, a nut sleeve 7, an outer sleeve 5, a mounting block 9, a screw rod 3, a thrust ball bearing 8, a big bevel gear 10, a horizontal rotary shaft 11, a small bevel gear 13 and the like, wherein the inner sleeve 2 is welded on the pedestal 1; the nut sleeve 7 is welded at the top end of the inner sleeve 2; the mounting block 9 is fixed on the outer sleeve 5 by a fastening screw; the screw rod 3 is screwed in a central screw hole of the nut sleeve 7 and in the mounting block 9 and is provided with a trapezoidal screw thread; the thrust ball bearing 8 is sleeved at the upper end of the screw rod 3; the big bevel gear 10 is sleeved at the upper end of the screw rod 3 and is fixed by a strip key; the horizontal rotary shaft 11 is arranged in two shaft sleeves one of which is small and the other one of which is big; and the small bevel gear 13 is sleeved on the horizontal rotary shaft 11 and is fixed by a strip key. The device adopts a driving mode with a manual rocker, big bevel gear-small bevel gear, and screw rod-nut sleeve, and has the characteristics of compact structure, convenient assembly and use, stable driving, labor-saving manual operation and the like.

Description

Mobile equipment supporting and retracting device
Technical field
The present invention relates to a kind of mobile equipment supporting and retracting device, it is specially adapted to middle-size and small-size mobile unit and after arriving the work-yard it is carried out on-the-spot support fixation.
Background technique
Equipment such as the pumping plant that draws water of middle-size and small-size movable type, concrete mixer, air compressor plant, diesel generator need the scene to carry out interim support fixation after moving to the work-yard.In background technique, the on-the-spot support fixation of present domestic large-scale mobile equipment in the work-yard all is to adopt the hydraulic pressure supporting and retracting device.Because hydraulic pressure supporting and retracting device cost is higher, system architecture is complicated, safeguard inconvenience, do not fit on middle-size and small-size mobile unit and use.Use simple and easy mechanical type supporting and retracting device and the on-the-spot support fixation of middle-size and small-size mobile unit is general, but it exists defectives such as stability of strutting system is relatively poor, folding and unfolding is inconvenient, manual operations effort.For overcoming these defectives, mobile equipment supporting and retracting device is developed.
Summary of the invention
Technical problem to be solved by this invention is that a kind of mobile equipment supporting and retracting device will be provided, it adopts manual rocking bar, bevel gear-bevel gear, the screw mandrel-nut sleeve kind of drive, has compact structure, characteristics such as easy for installation, stable drive, manual operations are laborsaving.
The technological scheme that the present invention solves its technical problem employing is: it comprises base, be welded in the inner sleeve on the base, be welded in the nut sleeve on inner sleeve top, outer sleeve, be fixed on the mounting blocks on the interior journal stirrup of outer sleeve with fastening screw trip bolt, spinning is with the screw mandrel of trapezoidal thread in nut sleeve center screw and mounting blocks, the thrust ball bearing that is set in the screw mandrel upper end and fixes by plain washer and circlip, the bevel gear wheel that is set in the screw mandrel upper end and fixes with the bar shaped key, be assemblied in the horizontal rotating shaft in small one and large one two axle sleeves, the bevel pinion that is set in horizontal rotating shaft and fixes with the bar shaped key, be assemblied in the rocking bar of horizontal rotating shaft, be set in the handle with sleeve of rocking bar, screw is in the top at outer sleeve top cover, be welded in the contiguous block of outer sleeve, bevel gear wheel and bevel pinion mesh fully, and contiguous block links to each other with mobile unit by welding.
The present invention compares the beneficial effect that is produced with prior art
1, adopt manual rocking bar, bevel gear wheel-bevel pinion, the trapezoidal thread screw mandrel-nut sleeve kind of drive, its stable drive, manual operations is laborsaving, efficient and reliability in the time of improving support and folding and unfolding effectively.
2, simple in structure, compact, easy to install, low cost of manufacture.
Description of drawings
Fig. 1 is the structural drawing of mobile equipment supporting and retracting device of the present invention.
Embodiment
Referring to accompanying drawing, inner sleeve 2 is welded on the base 1, nut sleeve 7 is welded in the top of inner sleeve 2, mounting blocks 9 is fixed on the interior journal stirrup of outer sleeve 5 by fastening screw trip bolt, screw mandrel 3 is set in mounting blocks 9 and spinning in the center screw of nut sleeve 7, thrust ball bearing 8 is set in the upper end of screw mandrel 3 and fixes with plain washer and circlip, bevel gear wheel 10 is set in the upper end of screw mandrel 3 also by bar shaped key and screw, horizontal rotating shaft 11 is assemblied in small one and large one two axle sleeves of outer sleeve 5, bevel pinion 13 is set in horizontal rotating shaft 11 1 ends and fixes with the bar shaped key, rocking bar 6 is assemblied on the horizontal rotating shaft 11, handle with sleeve 4 is set on the handle of rocking bar 6, top cover 12 is by the top of screw in outer sleeve 5, contiguous block 14 is welded on outer sleeve 5 over against the opposite side of rocking bar 6, be complete engagement after bevel gear wheel 10 and bevel pinion 13 are in place, contiguous block 14 links to each other with mobile unit by welding.
Working procedure
Every mobile unit four mobile equipment supporting and retracting devices of the present invention that need be welded.When mobile unit supports, rocking bar 6 is loaded on the horizontal rotating shaft 11, hold handle with sleeve 4, the 4 people rocking bar 6 that turns clockwise simultaneously, bevel pinion 13 on the horizontal rotating shaft 11 rotates, and drives bevel gear wheel 10 rotations on the screw mandrel 3, horizontally rotating of horizontal rotating shaft is changed into the vertical rotation of screw mandrel 3, screw mandrel 3 promotes inner sleeve 2 by nut sleeve 7 and moves downward, and up to four supporting and retracting devices mobile unit is raised up to suitable working depth and is adjusted into level.During the mobile unit folding and unfolding, 4 people are rotated counterclockwise rocking bar 6 simultaneously and get final product, and put in place up to four supporting and retracting device folding and unfoldings, put down mobile unit.
