Description
Technical field
The utility model relates to a kind of hanging device for car production manufacturing technology field, specifically a kind of lifting mechanism.
Background technology
In prior art, in workshop, for the crane of automobile lifting, rise in automobile process in lifting, the relative top of bottom support body support body is that track adjusting wheel by installing respectively at top support body lower surface and bottom support body upper surface is carried out do lifter motion.Due to crane top, assemblage gap that the error that exists when electric block brings is installed, this is just very large, uses guide wheel to cause gap larger, causes producing larger rolling momentum in the time of lifting carrying workpiece, and after working long hours, track adjusting wheel is also easily damaged.
In Automobile Enterprises production management process, usually need vehicle newly developed to carry out trial assembly trial-production, so that further perfect, in this process, automobile is lifted to carry out the omnibearing inspection work that is absolutely necessary, this just need to use jacking equipment.At present, normally used jacking equipment, owing to lacking necessary protective device, the situation of crane landing happens occasionally, cause very large potential safety hazard, in lifting process, there is unforeseen circumstances in equipment, guarantee the personal safety of operating personal, existing jacking equipment is carried out to necessary improvement and just seem particularly urgent.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of lifting mechanism, and what while adopting this lifting mechanism can effectively reduce lifting workpiece, produce rocks, and can effectively avoid lifting the situation that in workpiece process, support body comes off simultaneously and occur.
According to the technical solution of the utility model: a kind of lifting mechanism, comprise movable frame and be installed on the electric block on described movable frame top, described movable frame comprises the upper strata framework being fixedly installed and is connected in described upper strata base of frame and lower floor moving up and down framework, it is characterized in that: cross bar one end, framework bottom, described upper strata outer fork that is articulated and connected, and be provided with the first linear slide rail on the cross bar other end body of rod of framework bottom, upper strata; Described lower floor's framework top cross bar is provided with the second linear slide rail corresponding to first linear slide rail one end, and at lower floor's framework top cross bar other end interior fork that is articulated and connected, described interior fork is connected by shipping and reselling on another market with outer fork middle part, the described outer fork other end is slidably connected on the second linear slide rail by slide block, and the interior fork other end is slidably connected on the first linear slide rail by slide block.
As further improvement of the utility model, both sides, framework top, described upper strata are respectively equipped with protective stent, and be provided with locking rack on the driving surface of described protective stent, uniform several teeth that is provided with on locking rack, each tooth is mentioned ridge-shaped structure, and the tooth upper end of mentioned ridge-shaped structure is abrupt slope structure, lower end is gentle slope structure; Described lower floor's frame roof two ends are also respectively arranged with the anti-drop device matching with locking rack.
As further improvement of the utility model, described anti-drop device comprises a plinth and is fixed on the supporting seat on described plinth, blocking arm is connected in described supporting seat top by rotating shaft, and blocking arm is when in horizontality, and its front end stretches in locking rack and is resisted against abrupt slope body structure surface.
Technique effect of the present utility model is: in the utility model lifting mechanism, adopt linear slide rail, because linear slide rail is the gauge member that precision is very high, and can bear larger power and torque, can effectively reduce at work rolling momentum; In its deuterzooid product, owing to having set up anti-drop device, can effectively avoid the situation of crane landing, realize safety guard-safeguard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise electric block 1, outer fork 2, interior fork 3, upper strata framework 4, lower floor's framework 5, locking rack 6, tooth 6-1, abrupt slope structure 6-2, gentle slope structure 6-3, anti-drop device 7, the first linear slide rail 8, the second linear slide rail 9 etc.
As shown in Figure 1, the utility model is a kind of lifting mechanism, comprise movable frame and be installed on the electric block 1 on described movable frame top, described movable frame comprises the upper strata framework 4 being fixedly installed and is connected in framework 4 bottoms, described upper strata and lower floor moving up and down framework 5, described upper strata framework 4 cross bar one end, bottom outer fork 2 that is articulated and connected, and be provided with the first linear slide rail 8 on the upper strata framework 4 bottom cross bar other end bodies of rod; Described lower floor framework 5 top cross bars are provided with the second linear slide rail 9 corresponding to first linear slide rail 8 one end, and at lower floor's framework 5 top cross bar other ends interior fork 3 that is articulated and connected, described interior fork 3 is connected by shipping and reselling on another market with outer fork 2 middle parts, described outer fork 2 other ends are slidably connected on the second linear slide rail 9 by slide block, and interior fork 3 other ends are slidably connected on the first linear slide rail 8 by slide block.
Described anti-drop device 7 comprises a plinth and is fixed on the supporting seat on described plinth, blocking arm is connected in described supporting seat top by rotating shaft, and blocking arm is when in horizontality, and its front end stretches in locking rack 6 and is resisted against structure 6-2 surface, abrupt slope.
Working process of the present utility model is as follows: in the time promoting lifting workpiece, electric block 1 pulls lower floor's framework 7 upward movements, in lower floor's framework 7 upward movement processes, outer fork 4 and interior fork 5 are made relative sliding in the second linear slide rail 24 and the first linear slide rail 23, complete the upward movement of lower floor's framework 7.In lower floor's framework 7 uphill process, blocking arm front end slips over the structure 6-3 surface, gentle slope of locking rack 13 successively; And in the time of crane generation landing phenomenon, it is upper that blocking arm front end is resisted against abrupt slope structure 6-2, prevent that whole lift frame from coming off suddenly thereby reach, play the object of safety guard-safeguard.
In the utility model lifting mechanism, adopt linear slide rail, because linear slide rail is the gauge member that precision is very high, and can bear larger power and torque, can effectively reduce at work rolling momentum; In its deuterzooid product, owing to having set up anti-drop device, can effectively avoid the situation of crane landing, realize safety guard-safeguard.
