Abstract
The utility model discloses a two-way lifting device for a set of elevator safety tongs, belonging to the technical field of elevator safety. The key technical points are as follows: an upper cross beam is arranged on a lift car, rotating shafts are arranged on two sides of the upper cross beam and respectively and movably connected with a safety tongs connecting piece which is connected with a speed limiter by a steel wire rope, and a lifting rod is hinged between the rotating shafts and provided with an elastic reset mechanism. The two-way lifting device for the elevator safety tongs has a simple structure, is convenient to use and is used for ensuring the safety running of an elevator.
Description
Technical field
The utility model relates to a kind of elevator car safety, more particularly, relates in particular to the two-way pulling apparatus of a kind of elevator safety gear.
Background technology
At present, general elevator governor all is a side that is installed on the sedan-chair case, or left side or right side, on lift car, is equipped with and the corresponding safety tongs of velocity limiter, and the position of safety tongs generally is changeless.After elevator dispatches from the factory, if the field condition deviation make when velocity limiter can't place the predetermined design side, can only produce cooresponding with it safety tongs device again, so both prolonged the time that elevator is installed greatly, and expended material, increased use cost.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, provides a kind of elevator safety gear simple in structure, easy to use two-way pulling apparatus.
The technical scheme of the utility model is achieved in that the two-way pulling apparatus of a kind of elevator safety gear; Comprise the entablatrance on the car; Wherein said entablatrance both sides are provided with rotating shaft; In each rotating shaft, be connected with the safety tongs attaching parts respectively, the safety tongs attaching parts is connected through steel rope with velocity limiter; Between rotating shaft, be hinged with lifting rod, on lifting rod, be provided with flexible restoring organ.
In the two-way pulling apparatus of above-mentioned elevator safety gear, described elasticity accompanies mechanism to be made up of baffle plate, retracing spring and catch again; Said baffle plate one end is fixed on the entablatrance, and the baffle plate other end and catch all are set in lifting rod one end close end, and it is peripheral and between baffle plate and catch that said retracing spring is set in lifting rod.
In the two-way pulling apparatus of above-mentioned elevator safety gear, also be respectively equipped with pipe link between described two safety tongs attaching partss and the rotating shaft, each pipe link one end is captiveed joint with corresponding rotating shaft, and each pipe link other end and corresponding safety tongs attaching parts are hinged.
In the two-way pulling apparatus of above-mentioned elevator safety gear, be equipped with connecting rod between described lifting rod two ends and the rotating shaft, each connecting rod one end is captiveed joint with cooresponding rotating shaft respectively, and each connecting rod other end is hinged with cooresponding lifting rod one end respectively.
The utility model is all installed the safety tongs attaching parts through the both sides at entablatrance after adopting said structure, makes elevator when mounted; No matter which side velocity limiter is positioned at; Can cooperate with it, greatly facilitate the installation of elevator, the unmatched problem of safety tongs position and velocity limiter can not occur; Both save the time, reduced the expense of using again.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
Among the figure: entablatrance 1, rotating shaft 2, safety tongs attaching parts 3, lifting rod 4, flexible restoring organ 5, baffle plate 5a, retracing spring 5b, catch 5c, pipe link 6, connecting rod 7.
The specific embodiment
Consult illustrated in figures 1 and 2; The two-way pulling apparatus of a kind of elevator safety gear of the utility model comprises the entablatrance 1 on the car, is provided with rotating shaft 2 in entablatrance 1 both sides; In each rotating shaft 2, be connected with safety tongs attaching parts 3 respectively, safety tongs attaching parts 3 is connected through steel rope with velocity limiter; Between rotating shaft 2, be hinged with lifting rod 4, on lifting rod 4, be provided with flexible restoring organ 5, the flexible restoring organ 5 in the present embodiment is made up of baffle plate 5a, retracing spring 5b and catch 5c; Said baffle plate 5a one end is fixed on the entablatrance 1, and the baffle plate 5a other end and catch 5c all are set in lifting rod 4 one end close ends, and it is peripheral and between baffle plate 5a and catch 5c that said retracing spring 5b is set in lifting rod 4; Further, between two safety tongs attaching partss 3 and rotating shaft 2, also be respectively equipped with pipe link 6, each pipe link 6 one end is captiveed joint with corresponding rotating shaft 2, and each pipe link 6 other end and corresponding safety tongs attaching parts 3 are hinged; Between lifting rod 4 two ends and rotating shaft 2, be equipped with connecting rod 7, each connecting rod 7 one end is captiveed joint with cooresponding rotating shaft 2 respectively, and each connecting rod 7 other end is hinged with cooresponding lifting rod 4 one ends respectively.
During concrete the use, when velocity limiter places the left side, through the pulling of steel rope; Move on the left side safety tongs attaching parts 3; The cooresponding pipe link of green phase 6 drives rotating shafts 2 and rotates, and rotating shaft 2 drivening rods 7 rotate, and connecting rod 7 drives the lifting rods side shifting of turning left; Thereby pulling retracing spring 5b drives the safety device action.When placing the right side, be gearing equally through pipe link 6 and connecting rod 7, pulling apparatus leans on thrust to promote retracing spring 5b; The action of driving safety device; Dual mode is stressed identical, can both play the effect that makes 3 actions of safety tongs attaching parts, and its result of use is identical.The pulling apparatus of the utility model even under mounted situation, also can change the placement location of velocity limiter, and needn't do other changes.Can better place flexibly according to field condition, save time and material.
