Abstract
The utility model relates to a safety tong used for elevators for playing a protecting action for causing elevators to brake when elevators are overspeed. The safety tong comprises a tong main body, a fixed wedge block, an elastic body, a guiding slide block, a cover plate, a movable wedge block and a rolling body. In the utility model, the tong main body is provided with a half closed cavity body of which the middle position is provided with a gap which is penetrated through by an elevator guiding rail; the tong main body on one side of the guiding rail is provided with the fixed wedge block with the elastic body in a slide method; the tong main body on the other side of the guiding rail is fixedly provided with the guiding slide block; the movable wedge block is arranged between the guiding slide block and the guiding rail; the guiding slide block or the tong main body is fixedly provided with the cover plate which is used for guiding the movable wedge block; the rolling body is arranged between the movable wedge block and the guiding slide block and is a roller; the top end of the movable wedge block or the tong main body corresponding is provided with an adjusting screw bolt on the position corresponding to the top end of the movable wedge block. The utility model can ensure that the friction surface of the movable wedge block and the surface of the guiding rail can primely and tightly stick without need of higher precise oblique angles on the two sliding surfaces of the movable wedge block and the guiding slide block and simplifies the structure of safety tongs at the same time.
Description
Technical field
The utility model relates to a kind of elevator safety tongs, relates in particular to a kind of elevator safety gear of single roller/wedge combinations, 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, and rolling body is made up of retainer and roller, and roller can be ball or roller, is no less than 3 usually.The effect of rolling body is the power of reducing 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 cover plate is loaded on pincers body or the slider guide, in order to moving voussoir is led.The top of moving voussoir, or on the pincers body with cooresponding position, the top of moving voussoir, the adjusting bolt is housed, in order to the stroke of adjusting wedge.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.The one side in the face of guide rail of moving voussoir is a friction face, and the one side of facing slider guide is a sliding surface.For keeping the friction face parallel with guide rail surface (this point is very important for the braking effect of safety tongs, and only in this way, when safety tongs moved, voussoir friction face and guide rail surface could well be adjacent to) of moving voussoir.Therefore require two sliding surfaces that more accurate identical oblique angle should be arranged.
Summary of the invention
The purpose of this utility model provides a kind of can guarantee the to move friction face of voussoir and the elevator safety gear that guide rail surface is adjacent to well.
The utility model is to replace many rollers rolling body of the prior art with a roller, i.e. combination with " moving voussoir/a roller/slider guide " replaces the combination of " moving voussoir/contain the rolling body/slider guide of many rollers ".
Elevator safety gear of the present utility model comprises a pincers body, certain voussoir, an elastic body, a slider guide, a cover plate, a moving voussoir and a rolling body,
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 have the elastomeric voussoir of deciding, be installed with slider guide on the pincers body of guide rail opposite side, between this slider guide and guide rail, be provided with moving voussoir, be installed with the cover plate that moving voussoir is led on the slider guide or on the pincers body, be provided with rolling body between moving voussoir and the slider guide, described rolling body is a roller.
Described roller is located in the circular arc chamber of offering on the described moving voussoir.
With cooresponding position, the top of moving voussoir one adjustable bolt is housed on the top of described moving voussoir or the pincers body.
Described elastic body can be spiral, butterfly or flat spring.
The utility model can guarantee that the friction face and the guide rail surface of moving voussoir are adjacent to well, and does not require that two sliding surfaces of moving voussoir and slider guide have higher accurate oblique angle; Simultaneously, also simplified the structure of safety tongs greatly.
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 be along A to the local section enlarged drawing of roller.
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 nut 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 is cage guide 9 (cage guide does not belong to the parts of safety tongs), guide rail 9 opposite sides are voussoir 4, moving voussoir 4 has up-small and down-big wedge-like profile, the top of moving voussoir 4, or pincers body 1 on cooresponding position, the top of moving voussoir 4, be equipped with and regulate bolt 8, in order to the stroke of adjusting wedge.Moving voussoir 4 is a friction face in the face of the one side of guide rail, and the one side of facing slider guide is a sliding surface.Have a circular arc inner chamber on one side by sliding surface on moving voussoir 4, roller 10 of content is as rolling body.This roller 10 contacts with the sliding surface of slider guide 6, and 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.Cover plate 7 is loaded on pincers body 1 or the slider guide 6, in order to moving voussoir 4 is led.。
Owing between moving voussoir 4 and slider guide 6, have only a roller 10, even there is deviation in therefore moving voussoir 4 with two angle of bevel work in-processes of slider guide 6, the friction face that can both guarantee moving voussoir 4 is parallel with guide rail 9 surfaces, help improving the braking effect of safety tongs, reduced requirement simultaneously, and reduced cost for the angle of bevel working accuracy between moving voussoir 4 and the slider guide 6.
