Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rail detection equipment, in particular to an elevator guide rail measuring device. Background Art

[0002] In TSGT7001-2009 "Rules for Elevator Supervision Inspection and Periodic Inspection - Traction and Forced Drive Elevators", it is required that the distance deviation between the top surfaces of the two rows of guide rails is 0~+2mm for the car guide rail and 0~+3mm for the counterweight guide rail.

[0003] The distance deviation of the top surface of the guide rail is one of the factors that affect the ride comfort of the elevator. If the deviation is too large or too small, it will cause abnormal wear of related components and even affect the service life of the elevator. For elevators on high floors and with a long service life, the settlement of the floor will change the force on the elevator track, resulting in a change in the distance between the guide rails.

[0004] The existing method for detecting the deviation of the distance between the top surfaces of the guide rails is usually to manually select points for random inspection, which cannot complete the full coverage inspection of the entire guide rail; at the same time, the spacing between elevator guide rails is generally more than 1 meter, and the measurement result is within 3mm, which requires high accuracy. Manual inspection or general instrument inspection has jitter and vibration, resulting in large errors in the measurement results. Utility Model Content

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4, the utility model provides a technical solution:

[0022] like Figure 1-Figure 4 As shown, an elevator guide rail measuring device is located on the top of the car 1, including a control box 3, an adjustment component 4 and a laser rangefinder 5. A vacuum suction cup 301 is provided at the bottom of the control box 3, and the adjustment component 4 is located at the top of the control box 3. The adjustment component 4 includes a base 401 and a horizontal adjustment table. The base 401 is rotatably connected to the top of the control box 3, and the horizontal adjustment table is located above the base 401. Two groups of symmetrically arranged cylinders 405 are provided above the horizontal adjustment table. The two laser rangefinders 5 are respectively connected to the piston rods of the two cylinders 405. The measuring direction of the laser rangefinder 5 is toward the end face of the guide rail 2, and the laser rangefinder 5 and the cylinder 405 are respectively electrically connected to the control box 3.

[0023] Through the above technical solution, the measuring device is adsorbed on the top of the car 1 through the vacuum suction cup 301, so that the position of the laser rangefinder 5 can be adjusted by the vacuum suction cup 301 to ensure that the laser rangefinder 5 can illuminate the end face of the guide rail 2. After the vacuum suction cup 301 is adsorbed, the horizontal state of the laser rangefinder 5 is adjusted by adjusting the component 4 to ensure the level of the laser rangefinder 5 and improve the accuracy of the measurement. Then, the extended position of the laser rangefinder 5 can be adjusted by the cylinder 405 to avoid the obstructions on the car 1 as much as possible, so that the guide rail 2 can be effectively measured. Finally, the distance between the guide rail 2 is measured by the laser rangefinder 5, and the distances measured by the two laser rangefinders 5 respectively plus the distance between the two laser rangefinders 5 is the distance between the two guide rails 2.

[0024] The above device can reduce the measurement error during the installation process, facilitate adjustment, and ensure the accuracy of the final measurement.

[0025] Furthermore, the horizontal adjustment platform includes a support plate 404 and an adjustment support 402, the support plate 404 is located above the adjustment support 402 and is fixedly connected to the adjustment support 402, the cylinder seat of the cylinder 405 is fixed on the support plate 404, the laser rangefinder 5 is slidably connected to the support plate 404, and the four corners of the bottom of the adjustment support 402 are respectively provided with adjustment knobs 406, the fixed end of the adjustment knob 406 is connected to the base 401, and the movable end of the adjustment knob 406 is connected to the adjustment support 402.

[0026] According to the above technical solution, since there is an adjustment knob 406 at each of the four corners of the adjustment support 402, and a bubble for observing the horizontal state is provided on the adjustment support 402, the height of one side of the adjustment support 402 can be raised or lowered by fine-tuning the adjustment knob 406, and then the level of the support plate 404 and the laser rangefinder 5 on the support plate 404 can be adjusted by adjusting the knob 406.

[0027] At the same time, the cylinder 405 can drive the laser rangefinder 5 to extend and retract in the horizontal direction. The laser rangefinder 5 and the support plate 404 can use slide rails to improve the smoothness of sliding, or the laser rangefinder 5 and the support plate 404 can be suspended in the air to reduce friction.

[0028] Furthermore, the middle of the base 401 is inserted into the control box 3 and is rotatably connected to the control box 3. Locking screws 403 are provided on both sides of the base 401. The locking screws 403 are threadedly connected to the base 401, and the ends of the locking screws 403 abut against the top of the control box 3.

[0029] Through the above technical solution, in actual working conditions, the distance between the two guide rails 2 may have a certain angle with the center line of the car 1. In order to ensure that the two laser rangefinders 5 can respectively illuminate the end faces of the guide rails 2, the base 401 can be rotated to ensure the measurement effect, so that the laser rangefinder 5 can illuminate the end faces of the guide rails 2. After the base 401 is rotated to a good position, the locking screw 403 is tightened so that the locking screw 403 presses the control box 3 to ensure that the base 401 and the control box 3 no longer rotate.

[0030] Furthermore, the vacuum suction cup 301 includes a support seat, a vacuum cylinder and a valve, and the bottom of the control box 3 is fixedly connected to the support seat.

[0031] Through the above technical solution, after the vacuum suction cup 301 is placed on the top of the car 1, air is pumped out through a vacuum pump to ensure that the vacuum suction cup 301 and the car 1 are firmly adsorbed. After the measurement is completed, the air pressure balance is maintained through a valve so that the vacuum suction cup 301 can be removed.

[0032] Furthermore, a control system is provided in the control box 3, and the control box 3 is provided with a liquid crystal display screen and an alarm light, and the liquid crystal display screen and the alarm light are electrically connected to the control system respectively.

[0033] Through the above technical solution, the distance measured by the laser rangefinder 5 and the real-time measured distance between the guide rails 2 can be displayed on the LCD screen. When the distance between the guide rails 2 exceeds the limit value, the alarm light will sound. At the same time, all measured data will be recorded by the control system in the control box 3 for subsequent reading.

[0034] The specific implementation process is as follows:

[0035] refer to Figure 3 When the vacuum suction cup 301 is adsorbed to the top of the car 1, the measuring point of the laser rangefinder 5 is adjusted to be in the middle of the guide rail 2, so that the measuring points of the laser rangefinders 5 on both sides are at the same distance from the edge of the guide rail 2, that is, a=b in the figure is ensured. After adjusting the position, the vacuum suction cup 301 is adsorbed on the top of the car 1.

[0036] Then, the horizontal direction is adjusted by adjusting the knob 406 , and then the laser rangefinder 5 is extended to a certain distance by the cylinder 405 .

[0037] like Figure 4 As shown, the distance from the left laser rangefinder 5 to the left guide rail 2 is A, the distance from the right laser rangefinder 5 to the right guide rail 2 is C, and the distance between the two laser rangefinders 5 is B, so the distance between the two guide rails 2 is A+B+C. After starting the measurement, the values ​​of A, B, C and A+B+C can be displayed in real time on the LCD screen. At the same time, the control system enters the set value in advance. When the distance A+B+C exceeds the set value range, an alarm is issued. After the detection is completed, the maximum and minimum values ​​of A+B+C are automatically saved. The maximum and minimum values ​​of A+B+C are the measurement results.

[0038] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
