Technical Field
[0001] The utility model belongs to the technical field of elevator guide rails, and in particular relates to an automatic parallelism detection device for elevator guide rails. Background Art
[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types based on the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator. Therefore, the guide rails should be selected according to the elevator speed and load. The car guide rails are usually called the main rails, and the counterweight guide rails are called the auxiliary rails. After the elevator guide rails are processed, the parallelism of the guide rails needs to be tested.
[0003] The existing detection method is to measure the parallelism of the guide rails manually with a high-precision tape measure. The tape measure is used to measure multiple measurement points between the guide rails, and the measurement point data are compared and judged to determine whether the parallelism of the guide rails meets the standard. However, when the user uses the high-precision tape measure for measurement, it is manually operated. During long-term measurement work, the hand is very likely to shake due to the long guide rails, resulting in errors in the measurement data, which greatly reduces the accuracy of the measured data. Therefore, we provide an automatic detection device for the parallelism of elevator guide rails. Utility Model Content
[0004] The purpose of the utility model is to provide an automatic detection device for the parallelism of elevator guide rails, which is used by setting a motor, a threaded rod, a threaded sleeve, a cross bar, a connecting column and a work-shaped frame in conjunction with an electric telescopic rod, a clamping block, a connecting frame, a distance sensor, a display screen, a controller and a buzzer alarm to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic detection device for parallelism of elevator guide rails, comprising a base box, a connecting frame and a controller, a motor is fixedly installed on the left side of the base box, a threaded rod is fixedly connected to the output end of the motor, a threaded rod is threadedly connected to the surface of the threaded rod, a cross bar is fixedly connected to the front and back surfaces of the threaded sleeve, a connecting column is fixedly connected to the top of the cross bar, and a work-shaped frame is fixedly connected to the top of the two connecting columns, an electric telescopic rod is fixedly connected to the top of the work-shaped frame, a clamping block is fixedly connected to the bottom of the electric telescopic rod, the connection between the clamping block and the connecting frame is fixedly connected by bolts, distance sensors are fixedly connected to both sides of the inner side of the connecting frame, a display screen is fixedly connected to the top of the right side of the work-shaped frame, a buzzer alarm is fixedly connected to the front end of the top of the work-shaped frame, the distance sensor and the display screen are electrically connected by a first connecting line, and the controller and the buzzer alarm are electrically connected by a second connecting line.
[0006] By adopting the above scheme, the initial spacing is first input into the controller through the button on the surface of the controller. In the subsequent detection process, when the spacing is greater than or less than the initial spacing, it means that the parallelism does not meet the standard, and the electric telescopic rod drives the clamping block to move downward, and the clamping block drives the connecting frame to move downward, and the connecting frame drives the distance sensor to move downward until the distance sensor and the guide rail to be measured are on the same horizontal line and the movement stops. The height is adjusted by the electric telescopic rod so that the device can detect guide rails of different heights. After the height adjustment is completed, the threaded rod is driven by the motor to rotate. Because the external thread on the surface of the threaded rod is compatible with the internal thread on the inner wall of the threaded sleeve, when the threaded rod rotates, the threaded sleeve can be driven horizontally by the threaded rod. The guide rail is moved in a horizontal direction, the cross bar is driven to move horizontally through the threaded sleeve, the connecting column is driven to move through the cross bar, the I-frame is driven to move through the connecting column, and the I-frame, in cooperation with the electric telescopic rod, the clamping block and the connecting frame, can drive the distance sensor to move horizontally. During the movement of the distance sensor, the distance sensor and the guide rail are obtained, and the data is transmitted to the display screen and the controller. The data content is displayed on the display screen, and the input distance is compared with the initial distance through the controller. When the distance changes, the controller starts the buzzer alarm, and the buzzer alarm is used to remind the user that the parallelism of the guide rail does not meet the standard and needs to be reworked, thereby realizing automatic detection and greatly improving the accuracy of detection.
[0007] As a preferred embodiment of an automatic detection device for parallelism of elevator guide rails, guide grooves are provided on both sides of the bottom of the inner cavity of the base box, a guide rod is fixedly connected to one side of the bottom of the cross bar, and the bottom of the guide rod is slidably connected to the inner cavity of the guide groove.
[0008] By adopting the above scheme, the guide rod is limited by setting the guide groove, and the cross bar is assisted to move, so as to achieve the purpose of precise guidance.
[0009] As a preferred embodiment of an automatic detection device for parallelism of elevator guide rails, a positioning groove is provided on the bearing plate at the top of the base box, and the length of the positioning groove is consistent with the length of the bearing plate.
[0010] By adopting the above solution, the bottom of the guide rail to be measured is positioned by setting the positioning groove, so that the guide rails are on the same horizontal plane, thereby preventing the position of the guide rails from deviation.
[0011] As a preferred embodiment of the automatic detection device for parallelism of elevator guide rails, anti-skid pads are bonded around the bottom of the base box, and the number of anti-skid pads is four.
[0012] By adopting the above solution and providing the anti-skid pad, the base box has an anti-skid function, thereby further improving the stability of the device.
[0013] As a preferred implementation of an automatic detection device for parallelism of elevator guide rails, a power supply box is fixedly connected to the back of the I-frame, and a battery is provided in the inner cavity of the power supply box.
[0014] By adopting the above scheme, the electrical equipment is powered by the battery to maintain the normal operation of the electrical equipment.
[0015] As a preferred embodiment of an automatic detection device for parallelism of elevator guide rails, one end of the threaded rod is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the base box.
[0016] By adopting the above scheme, the bearing is set to reduce the wear of one end of the threaded rod during operation, thereby preventing it from getting stuck during subsequent operation due to severe wear.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The utility model drives the threaded rod to rotate by a motor. Because the external thread on the surface of the threaded rod is matched with the internal thread on the inner wall of the threaded sleeve, when the threaded rod rotates, the threaded sleeve can be driven to move laterally through the threaded rod, and the cross bar can be driven to move laterally through the threaded sleeve, and the connecting column can be driven to move through the cross bar, and the work-shaped frame can be driven to move laterally through the connecting column. With the cooperation of the electric telescopic rod, the clamping block and the connecting frame, the work-shaped frame can drive the distance sensor to move laterally. During the movement, the distance sensor obtains the spacing data between the distance sensor and the guide rail, and transmits the data to the display screen and the controller, and displays the data content through the display screen. At the same time, the controller compares the input spacing with the initial spacing. When the spacing changes, the controller starts the buzzer alarm, and the buzzer alarm is used to alarm to remind the user that the parallelism of the guide rail does not meet the standard and needs to be reworked, thereby realizing automatic detection and greatly improving the accuracy of detection.
[0019] 2. The utility model drives the clamping block to move downward through the electric telescopic rod, drives the connecting frame to move downward through the clamping block, and drives the distance sensor to move downward through the connecting frame until the distance sensor and the guide rail to be measured are on the same horizontal line and then the movement stops. The height is adjusted through the electric telescopic rod, so that the device can detect guide rails of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] See also Figure 1-3 , an automatic detection device for parallelism of elevator guide rails, comprising a base box 1, a connecting frame 10 and a controller 13, see Figure 1As shown, a positioning groove 15 is provided on the bearing plate at the top of the base box 1, and the length of the positioning groove 15 is consistent with the length of the bearing plate. By setting the positioning groove 15, the bottom of the guide rail to be measured is positioned so that the guide rail is on the same horizontal plane to prevent the position of the guide rail from deviation. A motor 2 is fixedly installed on the left side of the base box 1, and a threaded rod 3 is fixedly connected to the output end of the motor 2. A threaded sleeve 4 is threadedly connected to the surface of the threaded rod 3. The front and back surfaces of the threaded sleeve 4 are fixedly connected to a cross bar 5. A connecting column 6 is fixedly connected to the top of the cross bar 5, and a work-shaped frame 7 is fixedly connected to the top of the two connecting columns 6. Figure 2 As shown, the back of the work-type frame 7 is fixedly connected to a power supply box, and the inner cavity of the power supply box is provided with a battery. Through the setting of the battery, the electrical equipment is powered to maintain the normal operation of the electrical equipment. The top of the work-type frame 7 is fixedly connected to an electric telescopic rod 8, and the bottom of the electric telescopic rod 8 is fixedly connected to a clamping block 9. The connection between the clamping block 9 and the connecting frame 10 is fixedly connected by bolts. Both sides of the inner side of the connecting frame 10 are fixedly connected to distance sensors 11. The top of the right side of the work-type frame 7 is fixedly connected to a display screen 12. The front end of the top of the work-type frame 7 is fixedly connected to a buzzer alarm 14. The distance sensor The controller 11 and the display screen 12 are electrically connected through a first connecting line, and the controller 13 and the buzzer alarm 14 are electrically connected through a second connecting line. First, the initial spacing is input into the controller 13 through the button on the surface of the controller 13. In the subsequent detection process, when the spacing is greater than or less than the initial spacing, it means that the parallelism does not meet the standard. The electric telescopic rod 8 drives the clamping block 9 to move downward, and the clamping block 9 drives the connecting frame 10 to move downward. The connecting frame 10 drives the distance sensor 11 to move downward until the distance sensor 11 and the guide rail to be tested surface are on the same horizontal line. The movement stops, and the height is adjusted by the electric telescopic rod 8, so that the device can detect guide rails of different heights. After the height adjustment is completed, the threaded rod 3 is driven to rotate by the motor 2. Because the external thread on the surface of the threaded rod 3 and the internal thread on the inner wall of the threaded sleeve 4 are adapted, when the threaded rod 3 rotates, the threaded sleeve 4 can be driven to move horizontally by the threaded rod 3, and the cross bar 5 can be driven to move horizontally by the threaded sleeve 4, and the connecting column 6 can be driven to move by the cross bar 5, and the I-shaped frame 7 can be driven to move by the connecting column 6. With the cooperation, the distance sensor 11 can be driven to move horizontally. During the movement, the distance sensor 11 obtains the distance data between the distance sensor 11 and the guide rail, and transmits the data to the display screen 12 and the controller 13. The data content is displayed on the display screen 12. At the same time, the input distance is compared with the initial distance through the controller 13. When the distance changes, the buzzer alarm 14 is started by the controller 13, and the buzzer alarm 14 is used to alarm to remind the user that the parallelism of the guide rail does not meet the standard and needs to be reworked, thereby realizing automatic detection and greatly improving the accuracy of detection.
[0025] See Figure 3 As shown, guide grooves are provided on both sides of the bottom of the inner cavity of the base box 1, and a guide rod is fixedly connected to one side of the bottom of the cross bar 5, and the bottom of the guide rod is slidably connected to the inner cavity of the guide groove. By setting the guide groove, the guide rod is limited and the cross bar 5 is assisted to move, so as to achieve the purpose of precise guidance. Figure 1 As shown, anti-skid pads are glued on all four sides of the bottom of the base box 1, and the number of anti-skid pads is four. Through the provision of the anti-skid pads, the base box 1 has an anti-skid function, which further improves the stability of the device. One end of the threaded rod 3 is movably connected with a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the base box 1. Through the provision of the bearing, the wear of one end of the threaded rod 3 during operation is reduced, preventing it from being stuck during subsequent operation due to severe wear.
[0026] When in use, firstly, the guide rail is transported to one side of the base box 1 through the external transport mechanism, and then the bottom of the guide rail to be tested is clamped with the inner wall of the positioning groove 15, and the guide rail is positioned through the positioning groove 15 so that the guide rail is on the same horizontal plane to prevent the position of the guide rail from deviation. Secondly, the user inputs the initial spacing into the controller 13 through the button on the surface of the controller 13. In the subsequent detection process, when the spacing is greater than or less than the initial spacing, it means that the parallelism does not meet the standard, and then the clamping block 9 is driven downward by the electric telescopic rod 8, and the connecting frame 10 is driven downward by the clamping block 9, and the distance sensor 11 is driven downward by the connecting frame 10 until the distance sensor 11 and the guide rail to be tested surface are on the same horizontal line and the movement stops, so as to achieve the purpose of adjusting the height, so that the device can detect guide rails of different heights. After the height adjustment is completed, the threaded rod 3 is driven to rotate by the motor 2. Because the external thread on the surface of the threaded rod 3 and the internal thread on the inner wall of the threaded sleeve 4 are adapted, when the thread When the rod 3 rotates, the threaded sleeve 4 can be driven to move laterally through the threaded rod 3, and the cross bar 5 can be driven to move laterally through the threaded sleeve 4, and the connecting column 6 can be driven to move through the cross bar 5, and the I-shaped frame 7 can be driven to move laterally through the connecting column 6. The I-shaped frame 7 can drive the distance sensor 11 to move laterally with the cooperation of the electric telescopic rod 8, the clamping block 9 and the connecting frame 10. During the movement of the distance sensor 11, the distance sensor 11 obtains the distance data between the distance sensor 11 and the guide rail, and transmits the data to the display screen 12 and the controller 13, and the data content is displayed on the display screen 12. At the same time, the input distance is compared with the initial distance through the controller 13. When the distance changes, the buzzer alarm 14 is started by the controller 13, and the buzzer alarm 14 is used to alarm to remind the user that the parallelism of the guide rail does not meet the standard and needs to be reworked, thereby realizing automatic detection and greatly improving the accuracy of detection. If there is no change, it means that the parallelism of the guide rail meets the standard and can be put into subsequent use.
