Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] To address the problems existing in the prior art, this embodiment provides the following technical solution: an elevator guide rail maintenance and calibration device, comprising a calibration device body 1 and an adjustment mechanism 3. The adjustment mechanism 3 is located behind the first calibration frame 11 and the second calibration frame 12, and can effectively adjust the length of the first calibration frame 11 and the second calibration frame 12, enabling them to be installed and calibrated with guide rails in elevators of different sizes, greatly improving the practicality of the calibration device body 1. Simultaneously, a first calibration mechanism 4 and a second calibration mechanism 5 are provided at the front of the middle part of the calibration device body 1. The first calibration mechanism 4 and the second calibration mechanism 5 form multiple calibration mechanisms, which can improve the accuracy of elevator guide rail calibration.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the calibration device body 1 includes a first calibration frame 11 and a second calibration frame 12, which are arranged on the upper and lower sides. An adjustment frame 31 is slidably installed on the rear interior of both the first calibration frame 11 and the second calibration frame 12. Threaded holes 32 are opened on the left and right sides of the interior of the adjustment frame 31. The first calibration frame 11, the second calibration frame 12 and the adjustment frame 31 are fixed and limited by a threaded rod 33. The fixed threaded rod 33 can be unscrewed and pulled out, and the first calibration frame 11 and the second calibration frame 12 can be slid outwards. The distance of the guide rails of elevators of different sizes can be adjusted. After adjustment, the threaded rod 33 can be inserted into the interior of the first calibration frame 11, the second calibration frame 12 and the threaded hole 32 and tightened to limit the position.

[0029] Secondly, fixing blocks 2 are installed on the left and right sides of the rear end of the first calibration frame 11 and the second calibration frame 12. The fixing blocks 2 can be engaged and fixed with the elevator guide rail. Secondly, intermediate blocks 13 are installed in the middle of the first calibration frame 11 and the second calibration frame 12. The intermediate blocks 13 are connected by a connecting elastic rope 14. The connecting elastic rope 14 is elastic, so the distance between the first calibration frame 11 and the second calibration frame 12 can be adjusted.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, after the calibration device body 1 is installed, the support block 41 can be fixedly installed on the front side of the middle block 13 by bolts. The support block 41 is located in the middle of the first calibration frame 11 and the second calibration frame 12. Then, the laser pointer 42 can be placed above the middle of the support block 41. A limiting block 43 is installed on the front side above the middle of the support block 41 by a spring 44. The spring 44 has elasticity. When the laser pointer 42 is placed in the middle of the support block 41, the limiting block 43 can be pulled forward. At this time, the spring 44 will be stretched. After the laser pointer 42 is placed, the spring 44 can be released, and the limiting block 43 is released. Block 43 will spring back and fit tightly against the outside of laser pointer 42, which can limit the position of laser pointer 42. Secondly, a first calibration block 45 is installed on the front side of the lower middle part of the support block 41. The first calibration block 45 is vertically set below the laser pointer 42, so that the laser pointer 42 can be turned on and the laser pointer 42 will emit a beam of light downward. When the beam of light emitted by the laser pointer 42 is exactly at the center point of the first calibration block 45, it means that the elevator guide rail has not shifted. If the beam of light emitted by the laser pointer 42 does not hit the center point of the first calibration block 45, it means that the guide rail has shifted.

[0031] Secondly, a rotating rod 51 is rotatably installed inside the upper part of the support block 41. Connecting ropes 52 are symmetrically wrapped around the outer sides of the rotating rod 51. A calibration plumb bob 53 is installed at the lower end of the connecting rope 52. The calibration plumb bob 53 has a certain weight. A limiting rod 54 is slidably set on the lower outer side of the connecting rope 52. The supporting block 41 is fixedly connected to the outside of the limiting rod 54 for limiting. A rotating disk 55 is installed at the right end of the rotating rod 51. The rotating disk 55 is engaged with the upper right side of the support block 41 by a limiting strip 56 for limiting. The limiting strip 56 can be pulled out so that the rotating rod 51 can rotate.

[0032] The calibration hammer 53 falls downwards by its own weight. A limiting rod 54 is set on the outside of the connecting rope 52 to limit the movement of the calibration hammer 53, which can effectively prevent the calibration hammer 53 from shaking violently. The second calibration blocks 57 are symmetrically installed on the left and right sides below the support block 41. The second calibration blocks 57 are vertically located below the calibration hammer 53. That is, when the calibration hammer 53 falls, its lower end is inserted into the interior of the second calibration block 57, indicating that the guide rail has not shifted. If the calibration hammer 53 falls and its lower end is not inserted into the interior of the second calibration block 57, it indicates that the guide rail has shifted. After the calibration device is used, the rotating disk 55 can be rotated to wind up the connecting rope 52 and the calibration hammer 53 for convenient use later.

[0033] The working principle of this elevator guide rail maintenance and calibration device is as follows: An adjustment mechanism 3 is set on the rear side of the first calibration frame 11 and the second calibration frame 12, which can adjust the length of the calibration device body 1, enabling it to be connected and installed with guide rails of elevators of different sizes. A first calibration mechanism 4 and a second calibration mechanism 5 are set on the front side of the middle part of the calibration device body 1. The first calibration mechanism 4 and the second calibration mechanism 5 form a variety of calibration mechanisms, which can perform various forms of calibration on the elevator guide rail, thereby greatly improving the accuracy of calibration.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
