The elevator is an important vertical transportation vehicle in modern high-rise buildings and bears the safety responsibility of the flow of personnel materials in the buildings. In the course of elevator inspection and acceptance, various technical parameters of the elevator installation need to be inspected. Among the various technical tests described above, the testing of the brakes is particularly important. The main types of elevator brakes are drum and disc type, drum brakes, which due to their simple structure and low cost are commonly used in asynchronous motor hoists and in a substantial part in synchronous motor hoists, including most freight elevators and a substantial number of passenger elevators.
In daily inspection of an elevator brake, a lever drum brake is in a state that only one group of brake devices works for a long time due to excessive abrasion of brake shoes caused by poor adjustment or long-term contracting brake operation of the brake. Moreover, because the working clearance between the brake shoes and the brake hub is small, a group of brake shoes which fail often seems to be still attached to the brake hub when the elevator brakes, the brake shoes cannot be easily found by visual inspection, and when overload occurs or another group of brakes has a problem, an elevator safety accident can be caused, so that the life and property safety of people is threatened.
In view of this, the present invention provides an elevator flaring device 1000 that includes a base assembly 100 and a movable assembly 200. In the drawings of the present specification, fig. 1 is a schematic diagram of a top view structure of an elevator flaring device according to a first embodiment of the present invention, fig. 2 is a schematic diagram of a top view structure of an elevator flaring device according to a second embodiment of the present invention, fig. 3 is a schematic diagram of a top view structure of an elevator flaring device according to a third embodiment of the present invention, and fig. 4 is a schematic diagram of a side view structure of an elevator flaring device according to a third embodiment of the present invention in fig. 3.
In elevator detection, the detection of an elevator brake is particularly important, and is an important part related to the use safety of the elevator. The main types of elevator brakes are drum and disc type, drum brakes, which due to their simple structure and low cost are commonly used in asynchronous motor hoists and in a substantial part in synchronous motor hoists, including most freight elevators and a substantial number of passenger elevators. In the test process of testing the braking capability of the lever drum brake, because two groups of mechanical parts of the brake act simultaneously, the braking capability of the mechanical parts of a single group of the brake cannot be verified, and if the efficiency of the mechanical parts of the single group is reduced or the mechanical parts of the single group fail completely, the testing method is difficult to find according to the existing braking test method.
In order to solve the problem, in the technical scheme provided by the invention, the flaring device 1000 for the elevator comprises a base assembly 100 and a movable assembly 200, wherein the base assembly 100 is installed on one of the outer side surfaces of the elevator component 400 to be tested, and the movable assembly 200 comprises a movable pressing block structure 210 detachably installed on the base assembly 100 and a driving structure 220 for driving the movable pressing block structure 210; the movable pressing block structure 210 is used for extending into the elevator component 400 to be detected and enabling the elevator component 400 to be detected to deviate from the initial position under the driving action of the driving structure 220 so as to detect the working state of the elevator. For detecting the lever drum brake, the elevator can be powered off in advance, the flaring device 1000 of the elevator is inserted into the gap between the coil end cover 421 and the brake arm 422 of the elevator brake 420 under the power-off state, the force is applied by the flaring device 1000 of the elevator to overcome the pressure of the brake pressing spring, the brake on one side of the lever drum brake is opened, and the working state of the brake on the other side of the lever drum brake is checked. In the detection process, the base assembly 100 is abutted against the brake coil end cover 421, the movable pressing block structure 210 is abutted against the brake arm 422, and the driving structure 220 drives the movable pressing block structure 210 to expand the gap between the brake coil end cover 421 and the brake arm 422 of the elevator brake 420, so that the effect of overcoming the pressure of the brake pressing spring is achieved. At this time, since there is a large difference in weight between the counterweight side and the car side of the elevator, the elevator should be kept stationary when the brake pressing spring pressure of this side is cancelled, otherwise it indicates that there is a problem with the brake of the other side.
The driving structure 220 is effective to provide power to the movable assembly 200, and therefore, may be configured to function as the driving movable pressing block structure 210 without departing from the essence of the present invention. In particular, the amount of the solvent to be used,
the drive mechanism 220 includes a ratchet wheel 221, a drive handle 223, a drive pawl 222 and a check pawl 224 disposed on the base assembly 100, wherein the drive pawl 222 is disposed on the drive handle 223.
The movable pressing block structure 210 includes a pressing block 211, a scale 212 and a rack 213, wherein the pressing block 211 is disposed on the rack 213, and the scale 212 is disposed on the pressing block 211.
In the detection operation process, power is transmitted to the driving pawl 222 from the driving handle 223, the driving pawl 222 further transmits the power to the ratchet wheel 221, the ratchet wheel 221 is transmitted to the movable pressing block structure 210, the movable pressing block structure 210 enables the elevator component 400 to be detected to deviate from the initial position, the flaring gap is achieved, and the effect of detecting the working state of the elevator is achieved.
Further, the driving structure 220 includes a ratchet wheel 221 engaged with the rack 213, a driving pawl 222 disposed on the driving handle 223, and a non-return pawl 224 disposed on the base assembly 100, wherein the driving pawl 222 drives the ratchet wheel 221, and the non-return pawl 224 is used for preventing the ratchet wheel 221 from rotating and providing a new starting point for the next driving process.
In the present embodiment, the power is transmitted from the driving handle 223 to the driving pawl 222, and the driving pawl 222 is transmitted to the ratchet wheel 221, so that the movable pressing block structure 210 moves. Since the elastic force of the brake pressing spring continuously acts on the movable pressing block structure 210, in order to prevent the movable pressing block structure 210 from being pushed back to the initial position by the elastic force in the force application interruption time, the non-return pawl 224 provided in the present embodiment can lock the ratchet wheel 221, prevent the ratchet wheel 221 from rotating, and ensure that the movable pressing block structure 210 does not rebound.
Further, the driving structure 220 includes a ratchet wheel 221, a non-return pawl 224 and a driving handle 223 disposed on the base 110, and a driving pawl 222 disposed on the driving handle 223, the driving pawl 222 is engaged with the ratchet wheel 221, the driving handle 223 is drivingly connected with the driving pawl 222, and the driving pawl 222 is used for driving the ratchet wheel 221 to rotate. In this embodiment, the movable pressing block structure 210 can be driven to move by manual driving. Manual force is applied to the driving handle 223 to drive the driving pawl 222 and further to move the ratchet wheel 221, and finally to move the movable pressing block structure 210. So set up, elevator flaring device 1000 structure is more simple, convenient to carry for detect operation convenient and fast more.
Because the flaring device 1000 of the elevator needs to extend into the gap between the coil end cover 421 and the brake arm 422 of the elevator brake 420, the detection operation is further simplified and is more convenient for holding. The base assembly 100 may further include a support handle 120 disposed alongside the drive handle 223, the support handle 120 being configured to support the base assembly 100. On the one hand, support handle 120 makes base assembly 100 support more stable, and on the other hand, support handle 120 is also convenient for hold, and the inspector both hands hold support handle 120 and actuating handle 223 respectively, simplify detection operation, promote detection efficiency.
As mentioned above, the flaring device 1000 for an elevator includes the base assembly 100 and the movable assembly 200; the movable assembly 200 comprises a movable pressing block structure 210 and a driving structure 220; wherein the content of the first and second substances,
To ensure smooth power transmission, the movement of the rack 213 is not deviated from the designed direction, and the power is smoothly transmitted to the movable pressing block structure 210. A guide block 140 may be disposed on the base assembly 100, the guide block 140 is pressed on the upper panel 160 and the lower panel 170 of the base assembly 100, the position of the guide block 140 is disposed corresponding to the ratchet wheel 221, and the guide block 140 is used for pressing against the ratchet wheel 221 and the rack 213 to transmit a lateral force generated when the force is transmitted, and guiding the rack.
Referring to fig. 1, in a preferred embodiment of the present invention, the operation procedure for detecting the operating condition of the lever drum brake by using the flaring device 1000 of the elevator is as follows: when the driving handle 223 swings clockwise and leftward, the ratchet wheel 221 is driven by the driving pawl 222 to rotate clockwise, so as to drive the rack 213 to move rightward, and the pressing block 211 fixed on the rack 213 opens rightward. Because the weight of the elevator counterweight side is greatly different from that of the elevator car side, when a brake shoe of the brake is separated from a brake drum, the elevator is kept still, otherwise, the brake on the other side is indicated to be problematic, if the situation occurs, the driving handle 223 can be immediately swung to the right to the bottom, so that the non-return pawl 224 is released, and under the action of the brake pressing spring, the movable pressing block structure 210 drives the rack 213 to move to the left, so that the brake on the side is put into operation, and the moving elevator is stopped.
In the drum brakes of elevators that are commonly used at present, the adjustment of the pressure value of the compression spring is very critical. The magnitude of the spring pressure can be adjusted through the compression nut, and the excessive or insufficient pressure of the compression spring can generate adverse effect on the braking of the elevator. When the spring pressure is too large, the electromagnetic force generated by the coil of the brake can not overcome the spring pressure and can not be completely and normally opened, so that the elevator dragging brake can operate; the spring pressure is too low to provide sufficient braking torque, which may prevent the elevator from braking properly. In both cases, elevator accidents may occur. Therefore, it is very necessary to measure the pressure of the lever drum brake hold-down spring to verify whether the spring pressure is within the range specified by the manufacturer when the elevator is regularly maintained and inspected.
Therefore, the flaring device 1000 for elevator further comprises a pressure detecting structure 300 detachably mounted on the pressure sensor support 150 of the base assembly 100 and abutting against the movable abutting block structure 210, wherein the pressure detecting structure 300 is used for measuring the acting force of the movable assembly 200 on the elevator component 400 to be tested. Specifically, the pressure detecting structure 300 includes a sensor 310 for monitoring pressure, and a pressure display table 320 for displaying a pressure value, wherein the pressure sensor 310 is abutted with the abutting block 211 to form a pair of acting forces. In addition, the pressure display meter support 330 is used for supporting the pressure display meter 320, the pressure display meter support 330 is provided with a U-shaped groove opening, and the screw and the butterfly nut arranged on the base assembly 100 can be inserted or pulled out through the U-shaped groove opening, so that the functions of quickly locking and disassembling the pressure sensor support 310 can be realized, and the requirements of different detection items can be met.
Referring to fig. 2, in another preferred embodiment of the present invention, the pressure sensor 310 of the pressure detecting structure 300 can be placed in the pressure sensor holder 150, and placed in the gap between the brake coil end cap 421 and the brake arm 422 of the lever drum brake together with the pressing block 211 of the movable pressing block structure 210, and when the driving handle 223 swings clockwise and leftward, the driving pawl 222 drives the ratchet wheel 221 to rotate clockwise, so as to drive the rack 213 to move rightward, so that the movable pressing block structure 210 fixed on the rack 213 opens rightward. Further, when the brake shoe is separated from the brake drum, the pressure of the brake hold-down spring can be obtained by simply converting the numerical value displayed on the pressure display gauge 320.
It should be further noted that in elevator supervision and inspection, periodic inspection, type test, commission inspection, accident investigation and other works, it is often necessary to detect the clearance values of the elevator landing door and the stressed car door and the locking efficiency of the door lock. In this case, it is necessary to apply a force to the landing door and the car door to measure the gap value of the door and the car door expanded by the force. Therefore, a scale 212 may be disposed on the movable pressing block structure 210, and a scale is correspondingly marked on the outer side surface of the upper panel 160 of the base assembly 100, and the scale 212 is correspondingly matched with the scale to measure the flaring gap value.
Referring to fig. 3 and 4, in a third embodiment of the present invention, in order to detect the gap value of the elevator landing door and the car door after being stressed, the present invention provides a method for detecting the gap value of the elevator landing door and the car door after being stressed. The landing door or car door can be pried to open a door gap by a simple tool (such as a screwdriver), then the pressure sensor 310 of the pressure detection structure 300 is placed in the pressure sensor support 150 and is placed in a proper position of the door gap together with the pressing block 211 of the movable pressing block structure 210, an inspector holds the support handle 120 by the left hand and operates the driving handle 223 by the right hand, when the driving handle 223 swings clockwise and leftwards, the ratchet wheel 221 is driven to rotate clockwise by the driving pawl 222, so that the rack 213 is driven to move rightwards, and the pressing block 211 fixed on the rack 213 is driven to open rightwards. When the pressure display gauge 320 displays a specified pressure value, the corresponding gap of the elevator landing door or the car door after being stressed can be directly read on the scale of the outer surface of the upper panel 160 of the base assembly 100 opposite to the scale 212, and the driving handle 223 can be swung to the right to the bottom after the measurement is finished, so that the check pawl 224 is released, and the door leaf can be reset.

The invention utilizes the driving structure 220 to drive the movable pressing block structure 210, thereby driving the elevator part 400 to deviate from the initial position, reading the displacement change through the scale 212 and realizing the displacement measurement; the driving handle 223 is operated to apply force, a pair of acting forces is formed by the abutting of the abutting block 211 and the pressure sensor support 150 or the pressure sensor 310, the pressure can be displayed through the display instrument, and flaring operation or force measurement is achieved.
