Description
Technical field
This utility model relates to elevator technology field, is specifically related to a kind of elevator fall arrest Manual brake control device.
Background technology
In recent years, along with the high speed development of China's economic society, elevator industry is rapidly expanded.Ending for the end of the year 2015, China's elevator total amount is more than 4,000,000, and with the speed increment of annual about 20%, elevator recoverable amount, annual production and annual increment are the first in the world.But, while being convenient for people to daily life, trip, the security incident that elevator causes emerges in an endless stream.There are elevator accident 49, dead 37 people altogether in the whole nation in 2014；Elevator accident 58 occurring altogether in 2015, dead 46 people, wherein elevator falling accident rapidly out of control accounts for more than seventy percent.Such as, on July 15th, 2015, the elevator of Huayang International Building, Shenyang, Liaoning is occurred to fall rapidly by 27 layers in 1 layer of running, and 12 people are injured；At night July 28, Guangzhou International Hotel one elevator in Xinyang City, Henan Province Huangchuan County falls rapidly, causes dead 1 people of 1 people severely injured.Through investigation and research, the reason causing these problems to occur is mostly that repair and maintenance work is not in place, causes Frequent Accidents because present stage elevator operating load is high, freight volume is big, use the cycle long.Elevator is in operation simultaneously, and no matter which kind of reason makes car exceed the speed limit; the danger even fallen; and in the case of every other safety guard is inoperative; then limiter of speed makes safety tongs generation linkage action, so that lift car stops automatically by the linkage linkage installed on elevator.But during accident, the most corresponding actively emergency measure in elevator, once there is pendant ladder accident, passenger can only feel simply helpless in car, without any means of saving oneself, leaves it to chance.When above-mentioned safety device breaks down, security incident will occur.
Summary of the invention
The purpose of this utility model is aiming at the defect that prior art exists, it is provided that a kind of simple to operate quickly, elevator fall arrest Manual brake control device that safety coefficient is high, it can improve Ability of emergency management when burst accident occurs in elevator.
Know-why of the present utility model is: this device is applied on vertical lift, on the basis of the original safety device of elevator, add standby a set of brake gear of emergency brake again, the speed of starting protection action is answered and during not service braking when elevator burst accident dramatic decrease in running exceedes elevator autoprotection device, operator on duty in elevator or passenger be forced helpless terrified in, quickly open the protection cap of Manual brake device, firmly drop-down hand-operated brake hands handle, connect the brake gear of handle and the connection system drive parking brake safety tongs of emergency brake parking brake safety tongs, buckle guide rail, slow down rapidly elevator falling speed or prevent lift slide at short notice, avoid sedan-chair to ruin people to die the generation of accident.
The technical solution of the utility model is: includes the linkage that links, also includes hand brake lever, parking brake stay cord, raising rod and parking brake safety tongs, and described hand brake lever connects linkage linkage by parking brake stay cord and controls its action；The both sides of described linkage linkage connect parking brake safety tongs by raising rod respectively, and described parking brake safety tongs is for being arranged on the both sides of cage guide.
Preferably, described parking brake safety tongs includes caliper and the wedge shape clamp block that in it, both sides are mounted opposite respectively by crossed strip, being coordinated by ball set inside described wedge shape clamp block and install wedge block, described raising rod is stretched into caliper by top and is connected with described wedge block.
Preferably, in described hand brake lever is placed on hand-operated brake protection cap.
This utility model is simple, practical, is installed on elevator, it is possible to by active operation, quickly prevents car and continues to fall, and gains time for professional's rescue, it is to avoid the generation of people's injures and deaths event eaten by elevator, greatly reduces security incident rate.

Detailed description of the invention
With reference to Fig. 1-4, a kind of elevator fall arrest Manual brake control device, including hand brake lever 3, parking brake stay cord 4, linkage linkage 5, raising rod 7 and parking brake safety tongs 6；Hand brake lever 3 is placed in hand-operated brake protection cap 2, and hand-operated brake protection cap 2 is installed protection cap handle 1, and hand brake lever 3 connects linkage linkage 5 by parking brake stay cord 4 and controls its action；The both sides of linkage linkage 5 connect parking brake safety tongs 6 by raising rod 7 respectively, and parking brake safety tongs 6 is for being arranged on the both sides of cage guide.
Parking brake safety tongs 6 includes caliper and the wedge shape clamp block 9 that in it, both sides are mounted opposite respectively by crossed strip 11, is coordinated by ball set 10 and install wedge block 8 inside wedge shape clamp block 9, and raising rod 7 is stretched into caliper by top and is connected with wedge block 8.
This device must install 2 gradual parking brake safety tongs in the outside left and right sides of lift car additional along guide rail, is positioned at the surface of original safety tongs.Hand brake lever and protection device are installed, with the activate switch device of stay cord attachment security pincers in higher position, cab interior side.When elevator occur out of control quickly fall time, use emergency manual brake gear, force elevator to stop rapidly, for wait professional person rescue gain time, it is to avoid the generation of casualties event.This device only resets when all safety switches, when car is lifted up, could discharge safety tongs.Safety tongs does not return to normal condition, and elevator can not be reused.
Fig. 5-6 is the structural representation of the elevator installing this device, the operation principle of this device: when taking elevator, aging because of elevator, overload, steel wire rope fracture and the brake gear such as former safety tongs malfunctioning and when causing elevator burst to fall, Elevator Operator or passenger catch rapidly protecting cover handle 1, open the hand brake device protection cap 2 being arranged on elevator cage side, promptly hand brake lever 3 is the most drop-down, parking brake stay cord 4 quickly pulls linkage linkage 5, thus handle parking brake safety tongs 6 both sides raising rod 7 mentioned simultaneously, move on wedge block 8, the wedge block 8 driving emergency safety pincers 6 the most under the action of the spring contacts with cage guide 13, two safety tongs are simultaneously clamped on cage guide 13, elevator is forced to stop rapidly.Meanwhile, when the linkage 5 that links is worked by force, the safety switch promoting lifting rod to handle is disconnected control circuit, forces brake dead electricity to also assist in retrosequence, quickly prevent car and continue to fall.By these stringent effort, gain time for professional's rescue, it is to avoid the generation of people's injures and deaths event eaten by elevator, thus serves the effect of elevator " patron saint ".
This device is simple, practical; with the thinking of innovation, this is circulated people's livelihood safety with regard to simple, conventional standby emergency measure; dissolve this social foci smoothly; " eating people's event " that the popular problem elevator paid close attention to the most of society takes place frequently is solved with less changing; dissolve Psychological phobia when people take elevator, be the currently or hereafter emergency protective device of China's elevator in a period of time.
