Description

Elevator safety gear
Technical field
The utility model relates to a kind of elevator safety tongs, relates in particular to a kind of elevator safety gear with the moving voussoir stroke of slider guide adjusting, plays the protective effect that makes the elevator brake when elevator overspeed.
Background technology
Present elevator safety gear comprises pincers body, spring, decides voussoir, moves voussoir, rolling body, slider guide, cover plate, adjusting bolt.The pincers body has a semi-enclosed cavity, and there is a breach middle part on the top wall, to hold cage guide.On one sidewall spring is housed, the spring opposite side is equipped with decides voussoir.The end face up and down of deciding voussoir matches with a chute of pincers body, decides voussoir horizontal sliding therein.The opposite side of deciding voussoir is cage guide (cage guide does not belong to the parts of safety tongs), and the guide rail opposite side is voussoir, and the opposite side of moving voussoir has rolling body (also can not having), and the effect of rolling body is to reduce friction.There is a little spring to collude lower end, rolling body is pulled to below (slider guide afterbody) at rolling body.The opposite side of rolling body is a slider guide, and slider guide is contained on another sidewall of pincers body.Constitute up-small and down-big wedge shape space between slider guide and the cage guide.Moving voussoir has up-small and down-big wedge-like profile, and its one side in the face of guide rail is a friction face, and the one side of facing slider guide is a sliding surface.Cover plate is loaded on pincers body or the slider guide, in order to moving voussoir is led.When the descending operation of elevator exceeds the speed limit; moving voussoir is subjected to velocity limiter and shift mechanism, and (velocity limiter and shift mechanism be not at the row of content of the present invention; this paper is not described) driving; upwards wedge the wedge shape space between slider guide and the cage guide, the jam-packed guide rail also makes and decides voussoir displacement, compression spring; produce an elastic force; move voussoir and decide the common clamping guide rail of voussoir, make elevator finally stop to move downward, play a protective role.But,, need to regulate bolt in its top installing in order to regulate the stroke of moving voussoir.Do not collide in order to make the adjusting bolt with parts such as guide rail or cover plates, must there be certain width at the cooresponding position of pincers body directly over the top of moving voussoir and the moving voussoir, but the shape of moving voussoir just is up-small and down-big, thereby the overall width of moving voussoir can not be too little, makes the overall width of safety tongs widen.
Summary of the invention
The purpose of this utility model provides a kind of elevator safety gear of regulating the stroke of moving voussoir by adjustment slider guide upper-lower position.
Elevator safety gear of the present utility model cooperates with cage guide, comprises a pincers body, certain voussoir, an elastic body, a slider guide, a moving voussoir and a cover plate,
This pincers body has a semi-enclosed cavity, there is a breach middle part, cage guide passes therethrough, be slidingly equipped with on the pincers body of guide rail one side and be with the elastomeric voussoir of deciding, be installed with slider guide on the pincers body of guide rail opposite side, be provided with the moving voussoir of up-small and down-big wedge shape between this slider guide and guide rail, be installed with the cover plate that moving voussoir is led on the slider guide or on the pincers body, it is characterized in that: the position of described slider guide can up-down adjustment.
Described slider guide is by being bolted on the pincers body, and this bolt hole is a slotted hole.
Be provided with a rolling body between described moving voussoir and the slider guide, at least one roller is housed in this rolling body, this rolling body also can be a roller.
Corresponding position is provided with one and regulates bolt on the pincers body above the slider guide.
Described elastic body can be spiral, butterfly or flat spring.
Adopt the utility model of said structure to make the fixed position of slider guide to adjust up and down, owing to needn't debug the joint bolt with cooresponding position, the top of moving voussoir on the top of moving voussoir or the pincers body, thereby the overall width of moving voussoir allows to do lessly, and the overall width of safety tongs is reduced.
Description of drawings
Fig. 1 is that the utility model is removed the structure of cover plate scheme drawing;
Fig. 2 is the structural representation that the utility model covers cover plate;
Fig. 3 is a perspective view of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprise pincers body 1, spring 2, decide voussoir 3, moving voussoir 4, rolling body 5, slider guide 6, cover plate 7, adjusting bolt 8.Pincers body 1 has a semi-enclosed cavity, and there is a breach middle part on the top wall, to hold cage guide 9.Spring 2 is housed on one sidewall, and spring 2 opposite sides are equipped with decides voussoir 3.This spring 2 can be spiral, butterfly or flat spring, also can replace with other elastic body.The end face up and down of deciding voussoir 3 matches with a chute on the pincers body, decides voussoir 3 horizontal sliding therein.The opposite side of deciding voussoir 3 is cage guide 9 (cage guide does not belong to the parts of safety tongs), and guide rail 9 opposite sides are voussoir 4, and moving voussoir 4 has up-small and down-big wedge-like profile.Slider guide 6 is contained on another sidewall of pincers body 1.Constitute up-small and down-big wedge shape space between slider guide 6 and the cage guide 9, be suitable for installing moving voussoir 4.Moving voussoir 4 is friction faces in the face of the one side of guide rail 9, and the one side of facing slider guide 6 is a sliding surface.Moving voussoir 4 and the slider guide 6 middle rolling bodys 5 that are equipped with; the effect of rolling body is to reduce force of sliding friction; this rolling body can be made up of retainer and one or several rollers; roller can be ball or roller; also can be without retainer; directly a roller is located on the moving voussoir and is opened in the circular arc cavity, also can not establish rolling body.There is a little spring to collude, rolling body 5 is pulled to below (slider guide afterbody) in the lower end of rolling body 5.Shown in 2, cover plate 7 is loaded on the pincers body 1 or on the slider guide 6 as shown, in order to moving voussoir 4 is led.Slotted hole is made in order to the fixing bolt hole 10 of slider guide 6 in the side of pincers body 1, but make the fixed position up-down adjustment of slider guide 6, make the variable-width of wedge shape space between guide rail 9 and the slider guide 6, thereby regulated the stroke of moving voussoir 4, the top of moving voussoir 4, or on the pincers body 1 with cooresponding position, the top of moving voussoir 4, can not debug the joint bolt, it is less that the overall width of moving like this voussoir 4 allows to do, thereby the overall width of safety tongs 1 is reduced.For easy to adjust, also can on square tongs body 1 on the slider guide 6, an adjusting bolt 8 be set corresponding position.Because it is far away apart from guide rail 9, can not collide with guide rail.
