Abstract
The utility model discloses a pawl protector which comprises a rack, a pawl and a connecting rod triggering device. The rack is disposed on a mast standard section of a lifter. The pawl and the connecting rod triggering device are hinged to lifter cages on two sides of the rack respectively. The pawl is matched with the rack. The connecting rod triggering device is connected with a load bearing steel wire rope. A first pull spring which is connected with the pawl is disposed on the lifter cage hinged with the pawl. A second pull spring which is connected with the connecting rod triggering device is disposed on the lifter cage hinged with the connecting rod triggering device. The pawl protector is simple in structure. When the lifter accidentally falls, the pawl protector is triggered firstly to bear impact load directly, and accordingly normal operation of a falling protector is guaranteed, the lifter is safer in use, and safety accidents are reduced.
Description
Technical field
The utility model relates to the elevator safety device, relates in particular to a kind of ratchet fender guard.
Background technology
Elevator carries out playing an important role aspect vertical transport personnel and the goods in producing, living, and its safe reliability more and more is taken seriously.The grave accident of the weight-lifting equipment such as hoisting crane, electric block is malfunctioning because of lifting machine off-axis, service brake often, and the weight hypervelocity tenesmus that the gear tooth breakage of retarder or intermediate connector get loose etc. and to cause causes the grave accident of equipment personal injury.
The safety guard that present domestic elevator generally adopts mostly is single falling protector; certain potential safety hazard is arranged, when elevator meets accident when falling since moment the enormous impact load that produces; the gear of falling protector end may be destroyed, cause falling protector to lose efficacy and the injures and deaths of falling.
The utility model content
The technical matters that the utility model solves is: this device is intended at cage one cover ratchet fender guard being installed; meet accident when falling at elevator; the ratchet fender guard moves first; the enormous impact load that will produce moment turns by ratchet bears; guarantee that the falling protector end gear is stressed little; even the ratchet fracture can not affect the falling protector normal operation yet.
For reaching this purpose, the utility model by the following technical solutions:
A kind of ratchet fender guard; comprise tooth bar, ratchet and connecting rod flip flop equipment; described tooth bar is arranged on the elevator lower mast standard knot; difference hinged claw and connecting rod flip flop equipment on the cage of described tooth bar both sides; described ratchet matches with tooth bar; described connecting rod flip flop equipment connects the load-bearing wires rope, is provided with the first extension spring on the described cage and is connected with ratchet, is provided with the second extension spring on the described cage and is connected with the connecting rod flip flop equipment.
Further, be connected the load-bearing wires rope on the jointed shaft of described connecting rod flip flop equipment and cage.
Preferably, all to adopt spring wire be material for described the first extension spring, the second extension spring.
Further, described connecting rod flip flop equipment comprises mounting rod and frizzen, described connecting rod flip flop equipment is hinged on the cage by mounting rod one end, and what described frizzen was vertical with mounting rod is arranged in the middle part of the mounting rod and towards ratchet, and described connecting rod flip flop equipment is the integral type structure.
The beneficial effects of the utility model are: simple in structure, meet accident when falling at elevator; at first trigger the ratchet fender guard, by the ratchet fender guard load that directly withstands shocks, thereby guarantee the normal operation of falling protector; elevator is used safer, the generation of decrease safent accident.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is ratchet fender guard structural representation described in the utility model.
Among the figure:
1, tooth bar; 2, ratchet; 3, connecting rod flip flop equipment; 4, load-bearing wires rope; 5, the first extension spring; 6, the second extension spring; 7, mounting rod; 8, frizzen.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1, in the present embodiment, a kind of ratchet fender guard described in the utility model, comprise tooth bar 1, ratchet 2 and connecting rod flip flop equipment 3, described tooth bar 1 is arranged on the elevator lower mast standard knot, described elevator lower mast standard knot is hung oneself and is provided with cage, be respectively arranged with ratchet 2 and connecting rod flip flop equipment 3 on the cage of described tooth bar 1 both sides, described ratchet 2 is arranged on the active side that described tooth bar 1 has tooth, match with described tooth bar 1, described ratchet 2 is hinged on the cage, and the first extension spring 5 that arranges by its working end pulls to tooth bar with it;
Described connecting rod flip flop equipment 3 comprises mounting rod 7 and frizzen 8, described mounting rod 7 is structure as a whole with frizzen 8, described connecting rod flip flop equipment 3 is hinged on the cage by mounting rod 7, and by described jointed shaft connection load-bearing wires rope 4, described mounting rod 7 middle parts are provided with frizzen 8, described frizzen 8 is perpendicular to described mounting rod 7, described frizzen 8 ends withstand on the ratchet 2, described mounting rod 7 also be fixed on cage on the second extension spring 6 be connected, described the second extension spring 6 is pulled away from ratchet 2 with connecting rod flip flop equipment 3.
It is material that spring wire is all adopted in described the first extension spring 5, the second extension spring 6.
Make it keep state among Fig. 1 because load-bearing wires rope 4 is in its tension linkage flip flop equipment 3 of tight state during normal working, this moment, frizzen 8 held out against ratchet 2 so that ratchet 2 can not contact with tooth bar 1; When the load-bearing wires rope 4 that meets accident is in relaxation state, cage falls uncontrolled, this moment, the effect lower link flip flop equipment 3 in the second extension spring 6 rotated around jointed shaft, make frizzen 8 away from ratchet 2, ratchet 2 rotates to tooth bar 1 under the effect of the first extension spring 5, final its working end snaps in the rack tooth, alleviates the impulsive force that the cage hypervelocity falls to producing.
What need statement is; the above-mentioned specific embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with easily expected or replacement all should be encompassed in the protection domain of the present utility model.
