Compared with prior art, the utility model has following beneficial effect:
(1) the utility model is provided with the locking hook at the frame that spreads out, can lock the hanging device after being lifted, thereby avoided hanging device to occur to glide or fall, thereby improved greatly the safety in the use procedure, ensured the safety of the person with property;
(2) the utility model is provided with fixed mount at hanging device, this fixed mount is fixed on the frame that spreads out and can moves up and down along the frame that spreads out, avoided hanging device in motion process, to swing, thereby so that the person can not bump with hanging device with car body, further ensured the safety of the person with property;
(3) the utility model the utility model is provided be used to the bolt that is fixed on the frame that spreads out at the locking hook, will by bolt can be on the frame that spreads out fixing and locking hook everywhere, thereby can regulate according to the height that the hanging device needs rise the height of locking hook, so that it in use can be more flexible;
(4) the utility model is provided with oil cylinder at locking hook, thereby so that the better effects if of its locking, the weight that can support is larger, and needed control effort is less, has improved greatly its operability;
(5) the utility model is simple in structure, and is easy to use, produces and follows the cost of processing lower, can be good at producing on a large scale and using.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Core thinking of the present utility model is, a kind of slip-off preventing locking hook is provided, and the safety that has improved hanging device has reduced potential safety hazard, has further improved the efficient of its work and the incidence of accident, thereby has saved greatly the maintenance cost that uses.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, slip-off preventing locking hook comprises bracing or strutting arrangement, and the hanging device that links to each other with this bracing or strutting arrangement, also is provided with the locking hook on the described bracing or strutting arrangement.
Above-mentioned bracing or strutting arrangement comprises horizontally disposed crossbeam 1, and two framves 3 that spread out that vertically are arranged on this crossbeam 1 two ends downside, also is provided with the lifting electrical motor 2 that links to each other with hanging device by steel cable at this crossbeam middle part simultaneously.
Above-mentioned hanging device comprises weight 9, and the fixed mount 10 that is arranged on these both sides, weight 9 upper end.
As preferably, described fixed mount 10 also links to each other with the frame 3 that spreads out, and fixed mount 10 drives weights 9 and moves up and down along frame 3 directions of spreading out.
Above-mentioned locking hook comprises hook bearing 4, the hook 6 that links to each other with hook bearing 4, and simultaneously with link up with bearing 4 and link up with 6 oil cylinders that link to each other 5.
