Abstract
The utility model discloses the U-shaped mouth annunciator of a kind of safety tongs, it comprises elevator U hole safety tongs (1), guide rail (2), rubber cradle (3), also comprise detecting device (4), it is arranged on the plate body (5) in elevator U hole safety tongs (1) usually, and above-mentioned detection limit for detecting the contact friction degree of the U-shaped gap of described guide rail (2) and described U hole safety tongs (1), and is sent to elevator control circuit module by detecting device (4).The utility model can predict elevator safety state, reports to the police in advance, changes the parts that there is potential safety hazard in advance, improves the safety factor of elevator.Due to above-mentioned beneficial effect, the utility model is widely used in various elevator device.
Description
Technical field
The utility model belongs to elevators field, particularly relates to the safety system of elevator, specifically, relates to the U-shaped mouth annunciator of safety tongs.
Background technology
After elevator installation, enter the stage of being delivered for use, in elevator day-to-day operation, lead boots and easily produce wearing and tearing, after leading boots wearing and tearing, due to elevator unbalance loading, block easily one-sided and rail friction carved by safety tongs, causes safety tongs to brake, and elevator stops, if sudden stop, it is psychological alarmed to cause the occupant in car.Lack pre-tip in current technology to lead boots and to wear and tear the detecting device causing safety tongs to brake, so class thing occurs time and again.
Summary of the invention
For above-mentioned defect, the utility model spy proposes the U-shaped mouth annunciator of a kind of safety tongs, and it can not only fill up the blank of prior art, also has other many useful effect.
The U-shaped mouth annunciator of safety tongs, comprise elevator U hole safety tongs 1, guide rail 2, rubber cradle 3, described guide rail 2 screens runs on the U-shaped gap of described U hole safety tongs 1, the described elevator U hole safety tongs 1 described in rubber cradle 3 support, also comprise detecting device 4, detecting device 4 is arranged on the plate body 5 of described elevator U hole safety tongs 1 usually, above-mentioned detection limit for detecting described guide rail 2 and the contact friction degree of the U-shaped gap of described U hole safety tongs 1, and is sent to elevator control circuit module by it.Above-mentioned detecting device 4 is generally pressure sensor device.
The beneficial effects of the utility model are: precognition elevator safety state, report to the police in advance, improve the safety factor of elevator.Owing to adopting said apparatus, when elevator unbalance loading, the actual conditions of elevator can be reported and submitted to elevator control circuit by detecting device, Elevator Monitoring monitor staff is made to know the potential safety hazard of current elevator, change relevant parts in advance, thus avoid the temporary term stop of elevator in normal course of operation, bring psychology fear and potential safety hazard to passenger.
Due to above-mentioned beneficial effect, the utility model is widely used in elevator device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Also by way of example the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the U-shaped mouth annunciator of safety tongs, comprise elevator U hole safety tongs 1, guide rail 2, rubber cradle 3, described guide rail 2 screens runs on the U-shaped gap of described U hole safety tongs 1, the described elevator U hole safety tongs 1 described in rubber cradle 3 support, also comprise detecting device 4, detecting device 4 is pressure sensor device, be arranged on the plate body 5 of described elevator U hole safety tongs 1, above-mentioned detection limit for detecting described guide rail 2 and the contact friction degree of the U-shaped gap of described U hole safety tongs 1, and is sent to elevator control circuit module by it.
Implementation procedure of the present utility model is: cage guide (cross section generally in T-shaped) screens runs on safety tongs U hole place, adjustment centering, when guide rail lead boots or carve block wearing and tearing produce unbalance loading time, guide rail touches the electro-insulating rubber on U-shaped mouth annunciator at first, at this moment, the detecting device on U-shaped mouth is also a kind of pressure sensor device, signal can be sent, Signal transmissions is to machine room electricity cabinet, and boots wearing and tearing are led in prompting, needs repair and maintenance to change accessory, because of pre-tip, avoid the possibility of safety tongs action.
Claims (2)
