Utility model content
The utility model in order to solve prior art and exist hoisting fixture complex structure, fixing is strong and do not have the special technical matters for motor vehicle wheels hoisting fixture, there is provided a kind of and can ensure the stationarity that wheel is sling, the skeleton symbol three-jaw lifting machine arm frock that controlling is better, operation number is few, this frock not only can be used in the lifting of motor vehicle wheels, is also applicable to the lifting of the larger parts of other weight simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of skeleton symbol three-jaw lifting machine arm frock, it comprises gripping portion, support section and lift part, described gripping portion is distributed on described support section circumferencial direction at interval of 120 degree, it is characterized in that: described gripping portion comprises hook and connecting rod, described support section comprises suspension rod, first hinge and the second hinge, described pulling part is divided into suspension ring, described first hinge is fixedly installed on the lower end of described suspension rod, described second hinge is slidably arranged between described suspension rod top and described first hinge, described hook upper end is connected with described second articulate, described small end is connected with described first articulate, the described connecting rod other end drives described hook to locate clamping by oblique pull mode.
Further, the connection location of described connecting rod and described hook is for apart from 1/3rd places linking up with length described in described hook upper end.
Further, described hook is made up of roofbolt and the grip block being arranged on roofbolt lower end, and the delivery position of described grip block and described roofbolt has a semi arch degree.
Further, described connecting rod is made up of connecting rod post and the connector that is arranged on described connecting rod post two ends, described connector respectively with described first hinge and described hook hinged.
Further, described first hinge and described second hinge are by articulated column and three the articulated joints formations being evenly arranged on described articulated column circumferencial direction.
Further, described suspension rod is specifically made up of king post and the suspension rod ring being movably arranged on described king post top, and described suspension rod ring is flexibly connected with described suspension ring.
Further, described hook is all flexibly connected by bearing pin, packing ring and spring cotter with between described connecting rod, the second hinge and described connecting rod with described first hinge.
Lifting machine arm frock of the present utility model, three-jaw clamping lift is convenient, easy positioning and clamping, steadily, structure is simple, cost is low in lifting, decrease the application of manpower during lifting, reduce productive costs, this frock is not only applied to motor vehicle wheels, also for the lifting of other workpiece, the application of this frock decreases manpower, reduces cost of labor.

Detailed description of the invention
As Figure 1-5, lifting machine arm frock of the present utility model, it comprises gripping portion, support section and lift part, described gripping portion is distributed on described support section circumferencial direction at interval of 120 degree, described gripping portion comprises hook 1 and connecting rod 2, described support section comprises suspension rod 5, first hinge 3 and the second hinge 4, described pulling part is divided into suspension ring 6, described first hinge 3 is fixedly installed on the lower end of described suspension rod 5, described second hinge 4 is slidably arranged between described suspension rod 5 top and described first hinge 4, described hook 1 upper end is flexibly connected with described second hinge 4, described connecting rod 2 upper end is flexibly connected with described first hinge 3, described connecting rod 2 other end drives described hook 1 to locate clamping by oblique pull mode, the connection location of connecting rod 2 and described hook 1 is for apart from 1/3rd places linking up with 1 length described in described hook 1 upper end, described hook 1 is made up of roofbolt 10 and the grip block 11 being arranged on roofbolt 10 lower end, described grip block 11 has a semi arch degree with the delivery position of described roofbolt 10, described connecting rod 2 is made up of connecting rod post 13 and the connector 12 being arranged on described connecting rod post 13 two ends, described connector 12 respectively with described first hinge 3 and described hook 1 hinged, described first hinge 3 and described second hinge 4 are formed by articulated column 14 and three articulated joints 15 being evenly arranged on described articulated column 14 circumferencial direction, described suspension rod 5 is specifically made up of king post 16 and the suspension rod ring 17 being movably arranged on described king post 16 top, described suspension rod ring 17 is flexibly connected with described suspension ring 6, described hook and described connecting rod, second hinge and be all pass through bearing pin between described connecting rod and described first hinge, packing ring and spring cotter are flexibly connected, flexibly, be easy to remove and repair.
When lifting machine arm frock of the present utility model uses, the hook of crane catches on suspension ring to lift by crane, and is manually put on workpiece by hook, pull suspension rod to promote, due to the effect of gravity, three hooks are drawn close from trend center, are clamped, workpiece can be accommodated and raise up, be put into the position of regulation.
Consider actual application, the place joined due to grip block and roofbolt has a semi arch degree, this semicircle radian can be good at workpiece to be contained in this place, workpiece can be located by the combined action of three grip blocks firmly, prevent the phenomenon that workpiece in course of conveying comes off, effectively ensure that the safety of production.
Consider actual application, suspension ring and the joint of suspension rod ring all adopt the mode of welding by its sealing, and when avoiding lifting by crane, stressed larger suspension ring damage, thus avoid the generation of industrial accident.
