Abstract
The invention discloses a connecting shaft locking structure of a scissor aerial work platform. The connecting shaft locking structure comprises a connecting shaft, wherein a shaft sleeve and a bearing are arranged at two ends of the connecting shaft; one end of the connecting shaft is fixed with the shaft sleeve by a bolt; and a jump ring is arranged at the other end of the connecting shaft. By using the locking structure of the connecting shaft, the shaft sleeve at one end of the connecting shaft is fixed with the connecting shaft by the bolt, the other end of the connecting shaft is only needed to be relatively fixed with the shaft sleeve by the jump ring; the bearing is arranged in the connecting shaft; the shaft sleeve is movably connected to a scissor bar; when a lifting device rises and falls, the scissor bar is rotated around the shaft sleeve, the shaft sleeve is also rotated, and the connecting shaft is driven to rotate by the rotation of the shaft sleeve, so that the relative rotation between the shaft sleeve and the connecting shaft does not occur, the friction between the shaft sleeve and the connecting shaft is reduced, the wear of the connecting shaft is relieved, the service life of the connecting shaft is prolonged, and the whole structure is simple in structure and convenient to use.
Description
?
Technical field
The present invention relates to a kind of adapter shaft of high-altitude operation platform.
Background technology
High-altitude operation platform is the product of serving the mobility aloft work such as every profession and trade aloft work, equipment safety check, maintenance.A kind of scissor aerial work platform is arranged in the high-altitude operation platform, and it rises device and comes the implementation platform lifting by cutting to fork.Cut and fork that to rise device be that scissors rod stack in layer by mutual cross-articulation assembles, hinged by adapter shaft between the scissors rod up and down, fork when rising device and carry out lifting when cutting, scissors rod rotates around adapter shaft, between scissors rod and the adapter shaft because frequent rotation, so it is larger to rub, therefore all overlapping on adapter shaft has axle sleeve that adapter shaft protection is reduced its wearing and tearing; But when scissors rod rotated, scissors rod drove axle sleeve and rotates, between the adapter shaft of axle sleeve and the inside or mutual pivoting friction can occur, thereby on affecting the service life of adapter shaft, and replacing adapter shaft trouble very.
Summary of the invention:
The object of the invention is to for above-mentioned situation, a kind of latch-up structure of cutting the adapter shaft of fork high-altitude operation platform is provided, adapter shaft and axle sleeve can be locked, thereby adapter shaft protection is reduced its wearing and tearing.
A kind of latch-up structure of cutting the adapter shaft of fork high-altitude operation platform comprises adapter shaft, and the two ends of adapter shaft are provided with axle sleeve, bearing, and adapter shaft one end is fixed by bolt and axle sleeve, and the adapter shaft other end is provided with jump ring.
Be provided with packing ring between described jump ring and the adapter shaft.
The present invention adopts the latch-up structure of above-mentioned adapter shaft, the axle sleeve of adapter shaft one end is fixed by bolt and adapter shaft, the adapter shaft other end only need to be relatively fixing with it with axle sleeve by jump ring, bearing is set in the adapter shaft again, be connected with scissors rod on the axle sleeve, in the time of the jack up unit lifting, scissors rod rotates around axle sleeve, and axle sleeve can and then rotate, and the axle sleeve rotation can drive adapter shaft and rotate together, can not relatively rotate between axle sleeve and the adapter shaft like this, thereby reduced friction between the two, the wearing and tearing that alleviated adapter shaft have prolonged its service life, and total is simple, and is easy to use.
Description of drawings:
Fig. 1 is structural representation one of the present invention.
Fig. 2 is structural representation two of the present invention.
Fig. 3 is the enlarged drawing at A place among Fig. 2.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further specified:
As Figure 1-3, a kind of latch-up structure of cutting the adapter shaft of fork high-altitude operation platform comprises adapter shaft 1, and the two ends of adapter shaft 1 are provided with axle sleeve 2, bearing 3, and adapter shaft 1 one ends are fixing with axle sleeve 2 by bolt 4, and adapter shaft 1 other end is provided with jump ring 5.Be provided with packing ring 6 between jump ring 5 and the adapter shaft 1.
Cut cutting to fork and rising device 8 and be used for job platform is carried out lifting of fork high-altitude operation platform, all be movably connected on the adapter shaft 1 between the scissors rod 9 of every one deck and the scissors rod of last layer, the two ends cover of adapter shaft 1 has axle sleeve 2, in the time of the jack up unit lifting, scissors rod rotates around axle sleeve 2, axle sleeve 2 can and then rotate, axle sleeve 2 rotates and can rotate together by drive adapter shaft 1, can not relatively rotate between axle sleeve 2 and the adapter shaft 1 like this, thereby reduced friction between the two, the wearing and tearing that alleviated adapter shaft have prolonged its service life, and total is simple, and is easy to use.
