Abstract
The utility model relates to a backward non-stop anti-loose guide shoe wedge block which comprises a guide shoe wedge block body, wherein symmetric sliding mounting grooves are formed in the two sides at the bottom end of the guide shoe wedge block body; a spring positioning mounting hole is formed between the two sliding mounting grooves; a pressure spring for pressing the guide shoe wedge block body to the bottom of an elevator roller wheel is assembled in the spring positioning mounting hole; a U-shaped groove for embedding and locking of an elevator pulley is formed in a position over the spring positioning mounting hole of the guide shoe wedge block; the top end surface of the guide shoe wedge block body is a wedge-shaped surface at an angle alpha. Compared with the prior art, the guide shoe wedge block has the advantages of simple structure, convenience for assembly and reliability for braking.
Description
Technical field
The utility model relates to the elevator brake parts, definite says so a kind ofly during for elevator faults, swings to the locking boots voussoir of leading of retaining.
Background technology
When preventing that elevator from breaking down, the elevator free falling causes serious accident, is provided with braking mechanism on the elevator; Traditional elevator braking mechanism complex structure not only exist to be installed inconvenience is set, and himself reliability is low, brings certain potential safety hazard.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of voussoir form, and is simple in structure, and the more fast braking of elevator falling speed more failure-free swing to the locking boots voussoir of leading of retaining.
For achieving the above object, the utility model provides following technical scheme: a kind of locking boots voussoir of leading of retaining of swinging to, include and lead boots voussoir body, it is characterized in that: the described both sides, boots voussoir body bottom of leading are provided with the groove that is slidingly installed that is symmetrically set, be slidingly installed at two and be provided with spring location and installation hole between the groove, be equipped with in the spring location and installation hole and will lead the top pressure spring of boots voussoir body top to the elevator idler wheel bottom, the described boots voussoir of leading is positioned at spring location and installation hole is provided with the terraced pulley embedding of power supply stop over against the top position U-lag, and described top end face of leading boots voussoir body is the lozenges of angled α.
By adopting technique scheme, when the elevator normal operation, elevator pulley is positioned at the U-lag top of leading the boots voussoir, lead the boots voussoir along with elevator slides synchronously, when elevator breaks down, lead the boots voussoir when elevator glides fast, receive corresponding detection signals, lead the bottom braking that the boots voussoir is headed into elevator pulley, be provided with lozenges owing to lead the boots voussoir, more fast in lift slide speed, elevator pulley and the thrust of leading between the boots voussoir are more big, brake more reliable, under the top pressure spring effect simultaneously, make that leading the boots voussoir cooperates with elevator pulley reliably, arranging when on the one hand making things convenient for normal operation of U-lag, elevator pulley are not interfered after the assembling with leading between the boots voussoir, when braking, the braking contact surface of leading between boots voussoir and the elevator pulley increases, and brakes more stable.
The utility model further is set to: the angle [alpha] of described lozenges is 2 ° ~ 5 °.
By adopting technique scheme, pulley damages easily with to lead boots voussoir thrust excessive during the excessive then lift slide of lozenges angle [alpha], and the too small then braking effect of angle [alpha] is poor.
The utility model further is set to: described U-lag bottom surface of leading on the boots voussoir body is and being obliquely installed that described lozenges tilt angle alpha equates.
By adopting technique scheme, the U-lag bottom surface is adopted and is obliquely installed, and improves the braking potential of leading the boots voussoir.
The utility model further is set to: described U-lag of leading on the boots voussoir body is that opening portion is big, the structure setting that the bottom is little.
By adopting technique scheme, when further guaranteeing the elevator normal operation, elevator pulley is not interfered after the assembling with leading between the boots voussoir, and is convenient for assembly, and make assemble compacter.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 swings to the locking structural representation of leading the boots voussoir of retaining for the utility model specific embodiment;
Fig. 2 leads the front view of boots voussoir body for the utility model specific embodiment;
Fig. 3 leads the lateral plan of boots voussoir body for the utility model specific embodiment.
The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the disclosed a kind of locking boots voussoir of leading of retaining of swinging to of the utility model, include and lead boots voussoir body 1, the described both sides, boots voussoir body 1 bottom of leading are provided with the groove 11 that is slidingly installed that is symmetrically set, being slidingly installed at two is provided with spring location and installation hole 12 between the groove 11, be equipped with in the spring location and installation hole 12 will lead boots voussoir body 1 top to the top pressure spring 2 of elevator idler wheel bottom; The described boots voussoir body 1 of leading is positioned at spring location and installation hole 12 is provided with the terraced pulley embedding of power supply stop over against the top position U-lag 13, and U-lag 13 is that opening portion is big, and the angle that the little structure in bottom arranges its opening is 8 °, realistic requirement; Described top end face of leading boots voussoir body 1 is the lozenges 14 of angled α; The angle [alpha] of lozenges is 9 ° ~ 15 °, and the angle [alpha] of lozenges 14 is 2 ° ~ 5 °.Pulley damages easily with to lead boots voussoir thrust excessive during the excessive then lift slide of lozenges 14 angle [alpha], and the too small then braking effect of angle [alpha] is poor.In this specific embodiment, spring location and installation hole 12 is the through hole setting, when mounting spring 2, spring mounting hole 12 is positioned at an end of the leading boots voussoir body 1 small end pad of packing into, and spring 2 is packed into from an end of leading boots voussoir body 1 big end.
For further improving braking effect, described U-lag 13 bottom surfaces of leading on the boots voussoir body 1 are and being obliquely installed that described lozenges 14 tilt angle alpha equate.Arrange down like this, U-lag 13 bottom surfaces are adopted and are obliquely installed, and improve the braking potential of leading the boots voussoir.
When the elevator normal operation, elevator pulley is positioned at U-lag 13 tops of leading the boots voussoir, lead the boots voussoir along with elevator slides synchronously, when elevator breaks down, lead the boots voussoir when elevator glides fast, receive corresponding detection signals, lead the bottom braking that the boots voussoir is headed into elevator pulley, because leading the boots voussoir is provided with lozenges 14, more fast in lift slide speed, elevator pulley and the thrust of leading between the boots voussoir are more big, brake more reliable, under the top pressure spring effect simultaneously, make that leading the boots voussoir cooperates with elevator pulley reliably, during one side is set makes things convenient for normal operation of U-lag 13, elevator pulley and lead between the boots voussoir assembling after do not interfere, when braking, the braking contact surface of leading between boots voussoir and the elevator pulley increases, and brakes more stable.
