Abstract
The invention discloses a crane support leg side surface locking device. The crane support leg side surface locking device comprises a handle, a locking shaft, a guide base, a retainer ring, a retainer ring groove, a guide groove and a thread hole, and is characterized in that a longitudinal cylinder channel is formed in the guide base; the F-shaped guide groove is formed in the wall body of the guide base; the retainer ring groove is formed in the end part of the guide base; the thread hole is formed in the side surface of the locking shaft; a thread is arranged at the end part of the handle; the handle is in threaded connection with the locking shaft; the locking shaft is driven by the handle to slide in the cylinder channel; and the retainer ring is mounted in the retainer ring groove at the end part of the guide base. The crane support leg side surface locking device has such advantages of being simple in structure and easy to mount and operate.
Description
technical field:
Patent of the present invention belongs to special-use vehicle technical field, particularly relates to a kind of crane support lateral locking device.
technical background:
In crane products, telescopic leg is widely used, and in order to prevent movable supporting legs from controlling the situation lower slider of inefficacy at other, generally all can arrange supporting leg latching device, realizing the mechanical interlocking of supporting leg, ensure driving and construction safety.
summary of the invention:
Patent of the present invention aims to provide a kind of easy to operate crane support lateral locking device.
It is implement like this that patent of the present invention solves the technical scheme that its technical matters adopts: a kind of crane support lateral locking device, comprise handle, lock shaft, guide holder, back-up ring, circlip groove, guide groove, tapped bore, it is characterized in that: guide holder is provided with longitudinal cylindrical channel, wall body is provided with F type guide groove, end is provided with circlip groove; Lock shaft side is provided with tapped bore; Handle end is provided with screw thread; Handle is threaded with lock shaft, and lock shaft, under the drive of handle, slides in cylindrical channel, and back-up ring is arranged in the circlip groove of guide holder end.
Patent of the present invention have structure simple, simple, simple operation and other advantages is installed.
accompanying drawing illustrates:
Fig. 1 is the assembling exploded view of patent structure of the present invention;
Fig. 2 is the non-locking constitution diagram of patent structure of the present invention;
Fig. 3 is the locking state figure of patent structure of the present invention.
In figure: 1. handle, 2. lock shaft, 3. guide holder, 4. back-up ring, 5. circlip groove, 6. guide groove, 7. tapped bore, 8. movable supporting legs side plate, 9. fixed supporting leg side plate.
detailed description of the invention:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of crane support lateral locking device, comprise handle 1, lock shaft 2, guide holder 3, back-up ring 4, circlip groove 5, guide groove 6, tapped bore 7, it is characterized in that: guide holder 3 is provided with longitudinal cylindrical channel, wall body is provided with F type guide groove 6, end is provided with circlip groove 5; Lock shaft 2 side is provided with tapped bore 7; Handle 1 end is provided with screw thread; Handle 1 is threaded with lock shaft 2, and lock shaft 2, under the drive of handle 1, slides in cylindrical channel, and back-up ring 4 is arranged in the circlip groove 5 of guide holder 3 end.
Embodiment: guide holder 3 is welded on fixed supporting leg side plate 9, movable supporting legs side plate 8 and fixed supporting leg side plate 9 are provided with circular port, and lock shaft 2 pierces into guide holder 3, and handle 1 is connected with the tapped bore 7 on lock shaft 2.When movable supporting legs is without the need to locking, be pulled to by handle 1 in the outside transverse groove of guide groove 6, now lock shaft 2 will slide in guide holder 3 completely, can not pass movable supporting legs side plate 8 and fixed supporting leg side plate 9, then movable supporting legs retractable.When movable supporting legs need be locked, be pushed into by handle 1 in the inner side transverse groove of guide groove 6, now lock shaft 2 through movable supporting legs side plate 8 and fixed supporting leg side plate 9, thus will lock movable supporting legs.
