Abstract
Instantaneous safety tongs of an elevator comprise a safety tong frame, a guiding screw, a limiting screw, a strengthening board, an adjusting nut, a pulling rod, a wedge block base, a baffle, a wedge block and a linkage board. According to the instantaneous safety tongs of the elevator, an instantaneous safety tong linkage mechanism and a progressive safety tong linkage mechanism are unified, relevant positions of installation of the safety tongs are unified, the cost of the safety tongs is reduced, installation positions and wedge block linkage mechanisms of a goods elevator and a passenger elevator are identical, and standard requirements are met.
Description
Technical field
The utility model relates to a kind of safety tongs, particularly a kind of elevator instantaneous safety.
Background technology
Elevator safety gear is the indispensable vitals of elevator as one of elevator important safety component.Elevator safety gear is divided into instantaneous formula and gradual two types.Instantaneous safety only is used for the car that command speed is less than or equal to 0.63m/s, is having under the situation of counterweight safety, and instantaneous safety is used for command speed and is less than or equal to the 1.0m/s counterweight.Progressive safety gear can be used for various speed conditions.Because the material cost height of progressive safety gear makes it on the high side, so under the situation that can adopt instantaneous safety, each producer adopts instantaneous safety substantially, especially the application on cargo lift is very extensive.Instantaneous safety is made up of caliper, voussoir, baffle plate, and caliper is welded to form after machine up by forging steel material, and the action of voussoir spurs two voussoirs respectively by two pull bars.Its volume is big, weight is big, and the voussoir action is spurred respectively by two pull bars, adjusts the gap inconvenience of two voussoirs and guide rail, and the connecting rod mechanism of its action is different with the connecting rod mechanism of object.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of elevator instantaneous safety, instantaneous formula and progressive safety gear interlinked mechanism have been unified, unified safety tongs relevant position has been installed, reduced the cost of safety tongs, identical with installation, the voussoir link gear of elevator safety tongs and satisfy standard-required.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of elevator is instantaneous
The formula safety tongs comprises safe tong holder, guider screw, stop screw, brace panel, setting nut, lifting rod, voussoir seat, baffle plate, voussoir and interlock plate; It is characterized in that: the voussoir seat is welded on the relief bracket, baffle plate is fixed on the voussoir seat, the pilot hole that guider screw passes block is screwed into voussoir, the spacing hole that stop screw passes the interlock plate is screwed into voussoir, interlock plate and lifting rod weld together, screw thread one end and the setting nut of lifting rod are connected, brace panel and voussoir seat and safe tong holder weld together.
As further improvement of the utility model: described baffle plate has oblique pilot hole.
As further improvement of the utility model: described interlock plate has long spacing hole.
Compared with prior art, the beneficial effects of the utility model are: the utility model has adopted the safety tongs caliper of steel plate bending and last lower installation board to be welded to connect, assist brace panel simultaneously, satisfy requirement of strength, reduced former safety tongs volume like this, weight also significantly reduces, greatly reduce material cost, voussoir is done the time spent at safety tongs and is moved simultaneously, adjust the gap of voussoir and guide rail when being convenient to install, the upper beam structure of elevator and Cargo Lift has so just been unified with gradual identical in the link gear of its action and installation site, pillar construction, the degree of product standardization is further improved, and work efficiency significantly promotes.

Fig. 1 is front view;
Fig. 2 is right elevation;
Fig. 3 is the interlock plate;
Fig. 4 is the interlock plate;
Fig. 5 is the interlock plate.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to figs. 1 through Fig. 5, a kind of elevator instantaneous safety comprises safe tong holder 1, leads
To screw 3, stop screw 4, brace panel 7, setting nut 9, lifting rod 10, voussoir seat 11, baffle plate 12, voussoir 13 and interlock plate 14; It is characterized in that: voussoir seat 11 is welded on the relief bracket 1, baffle plate 12 is fixed on the voussoir seat 11, the pilot hole 2 that guider screw 3 passes block 12 is screwed into voussoir 13, the spacing hole 15 that stop screw 4 passes interlock plate 14 is screwed into voussoir 13, interlock plate 14 and lifting rod 10 weld togethers, screw thread one end and the setting nut 9 of lifting rod 10 are connected, brace panel 7 and voussoir seat 11 and safe tong holder 1 weld together.
Described safe tong holder 1 comprises upper plate 5, support body 6 and lower plate 8.
Described voussoir seat 11 surrounds the trapezoid opening.
The shape of described voussoir 13 synthetic trapezoids.
Turn setting nut 9 when allowing lifting rod 10 upwards mention, voussoir 13 makes progress simultaneously, because voussoir seat 11 has the inclined-plane, voussoir 13 just along this inclined-plane upwards, the distance between two voussoirs 13 is also just along with the effect that reduces, play to step up, baffle plate 12 blocks voussoir 13, it can not outwards be deviate from, and the pilot hole 2 on the baffle plate 12 slides guider screw 3 in pilot hole 2, avoids voussoir 13 to draw close with in the middle of the purpose; Interlock has the spacing hole of two horizontal length under the plate 14, and stop screw 4 plate 14 that will link is extremely fixing with voussoir 13, has played guiding and position-limiting action.
In sum, after those of ordinary skill in the art reads the utility model file, according to
The technical solution of the utility model and technical conceive need not creative brainwork and make other various corresponding conversion scheme, all belong to the scope that the utility model is protected.
