Description
technical field:
The utility model 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:
The utility model aims to provide a kind of easy to operate crane support lateral locking device.
It is implement like this that the utility model 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.
The utility model have structure simple, simple, simple operation and other advantages is installed.
accompanying drawing illustrates:
Fig. 1 is the assembling exploded view of the utility model structure;
Fig. 2 is the non-locking constitution diagram of the utility model structure;
Fig. 3 is the locking state figure of the utility model structure.
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.
