It also has step-type treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment serving specified floors. A vertical elevator has a car that runs between at least two rows of vertical rigid guide rails. The coordination between the car and the guide rails is the most important factor in the ride comfort and the service life of the elevator. The level of the elevator car must be ensured during production. Measuring the level of the elevator is to measure the verticality of the four tracks of the elevator. When the tracks are completely vertical, the interior of the elevator can reach the optimal horizontal state.
[0003] The elevator horizontal calibration device in the prior art has the following problems: 1. The device is large in size, and the elevator car needs to be moved to the top of the device and placed therein to measure whether the elevator car is level. This is not only inconvenient to use, but also difficult to move the device; 2. The device cannot detect the side walls of the elevator car. During production, it is possible that the bottom of the car is horizontal but the side walls are not completely vertical, which has a certain impact on the overall stability of the elevator.

[0012] Preferably, a handle is fixedly connected to one side of the main box.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: through the arrangement of the spherical joint and the spherical sleeve, one side of the device with the support seat is placed on the inner bottom of the elevator, so that the four support seats are in contact with the elevator. In the initial state, the spherical joint and the spherical sleeve are completely retracted into the interior of the first storage groove, so the four support seats are completely horizontal. At this time, the device is placed in the elevator and the level bubble can be used to check whether the elevator is level. When the bubble is not located in the center of the window, the leveling knob at a corner of the bubble is rotated so that the leveling knob drives the threaded rod to rotate through the connecting rod. When the support seat moves downward, the inner wall of the spherical sleeve can be rotated arbitrarily under the action of the spherical joint, so that the support seat can be rotated to the ground under the action of the spherical sleeve and the fixed shaft. The surface fits well, so as to accurately judge the non-horizontal position of the elevator; through the setting of the straight arm and the dial, the opening and closing knob drives the worm to rotate through the rotating rod, thereby driving the worm wheel to rotate under the action of the meshing connection, and then the worm wheel drives the central axis and the rotating cylinder to rotate and drive the straight arm to rotate out of the second receiving groove. When the second receiving groove rotates until the side wall contacts the side wall of the elevator, since the central axis is fixedly connected to the dial, the dial will rotate synchronously when the straight arm rotates out of the second receiving groove, and the pointer is fixedly set inside the observation slot. Therefore, after the second receiving slot contacts the side wall of the elevator, the pointer can be used to observe whether the angle on the dial is vertical, so as to judge the verticality of the side wall of the elevator, and the value of the elevator vertical deviation can also be measured, so as to adjust the side wall of the car.

[0022] In an optional embodiment: a plurality of leveling knobs 8 are provided on the top of the main box body 1 just above the support base 2, a connecting rod 9 is rotatably connected to the top of the first receiving groove 3, a top of the connecting rod 9 is fixedly connected to the middle of the leveling knob 8, a threaded rod 10 is fixedly connected to the bottom of the connecting rod 9, the threaded rod 10 is threadedly connected to the middle of the threaded tube 4, a window 11 is provided on the top of the main box body 1, and a horizontal bubble 12 is provided just below the window 11.
[0023] It should be noted that when measuring whether the elevator is level, the side of the device with the support seat 2 is placed on the inner bottom of the elevator so that the four support seats 2 are in contact with the elevator. In the initial state, the spherical joint 5 and the spherical sleeve 6 are completely retracted into the first receiving groove 3, so the four support seats 2 are completely horizontal. At this time, the device is placed in the elevator to check whether the elevator is level through the horizontal bubble 12. When the bubble is not located in the center of the window 11, the leveling knob 8 at the corner where the bubble is biased is rotated, so that the leveling knob 8 drives the threaded rod 10 to rotate through the connecting rod 9, thereby driving the threaded cylinder 4 to slide downward inside the first receiving groove 3 under the action of the threaded rod 10, thereby pushing the support seat 2 to move downward to lift up the corner. When the support seat 2 moves downward, the spherical joint 5 is fixed under the action of the threaded cylinder 4, so the inner wall of the spherical sleeve 6 can be rotated arbitrarily under the action of the spherical joint 5, so that the support seat 2 can be rotated to fit the ground under the action of the spherical sleeve 6 and the fixed shaft 7, thereby improving the accuracy of the horizontal detection.
[0024] In an optional embodiment: a second receiving groove 13 is provided on the top of the main box body 1, a central shaft 14 is rotatably connected to one side of the second receiving groove 13, a rotating cylinder 15 is fixedly connected to the outer wall of the central shaft 14, a straight arm 16 is fixedly connected to the side wall of the rotating cylinder 15, a first rotating groove 17 is provided on one side of the second receiving groove 13, a worm gear 18 is provided inside the first rotating groove 17, the outer wall of the central shaft 14 is fixedly connected to the middle of the worm gear 18, a second rotating groove 19 is provided on one side of the first rotating groove 17, and a rotating cylinder 15 is fixedly connected to the side wall of the rotating cylinder 15. A rotating rod 20 is connected, and a worm 21 is fixedly connected to the outer wall of the rotating rod 20, and the worm 21 is meshed with the worm wheel 18.

When the second receiving slot 13 rotates until the side wall contacts the elevator side wall, since the central shaft 14 is fixedly connected to the dial 24, the dial 24 will rotate synchronously when the straight arm 16 rotates out of the second receiving slot 13, and the pointer 25 is fixedly arranged inside the observation slot 23. Therefore, after the second receiving slot 13 contacts the elevator side wall, the pointer 25 can be used to observe whether the angle on the dial 24 is vertical, thereby judging the verticality of the elevator side wall, and also measuring the value of the elevator vertical deviation, so as to adjust the car side wall.
