Technical Field

[0001] The utility model relates to the technical field of elevator installation, in particular to an elevator installation gap measuring device. Background Art

[0002] A vertical elevator is a type of lift that is powered by an electric motor and equipped with a box-shaped pod. It is used to transport passengers or goods in multi-story buildings. It has a car that runs between at least two rows of vertical rigid guide rails or guide rails with an inclination angle of less than 15 degrees. The size and structure of the car are convenient for passengers to enter and exit or for loading and unloading goods. During the installation of the elevator, door sills need to be installed between each floor to facilitate the parking of the elevator car. The gap between the elevator car sill and the door sills of each floor is an important observation indicator for common elevator operation problems, such as people being pinched by the floor door, shearing at the floor door, and door pulling. Therefore, the reliability of the floor door closure is an important part of ensuring its safe operation.

[0022] The driving mechanism 10 includes a motor 101 and a connecting rod 104. The upper end of the connecting rod 104 is fixedly connected to a driving gear 106. The output shaft of the motor 101 is transmission-connected to the rotating shaft 102. The lower end of the rotating shaft 102 passes through the connecting plate 8 and is fixedly connected to a first gear 103. The lower end of the connecting rod 104 is fixedly connected to a second gear 105 meshing with the first gear 103. A tooth groove 31 is provided on the outer side of the driven guide rod 3, and a plurality of groups of teeth 32 meshing with the driving gear 106 are provided in the tooth groove 31.

[0023] A mounting hole 15 for rotationally connecting the connecting rod 104 is provided on one side of the fixed plate 1, and the driving gear 106 is arranged in the inner cavity of the mounting hole 15. The first gear 103 and the second gear 105 are both arranged below the connecting plate 8. The first gear 103 engages with the second gear 105 to drive the driving gear 106 to rotate through the connecting rod 104, thereby realizing the adjustment of the position of the movable plate 2 and improving the adjustment efficiency.

[0024] A screw hole 18 connected to the third hole 17 is provided on one side of the fixing plate 1 adjacent to the first socket 14. A locking bolt 19 is threadedly connected to the screw hole 18. An anti-slip pad 20 is adhered to the end of the locking bolt 19 close to the third socket 17. The anti-slip pad 20 on the locking bolt 19 is used to contact the measuring plate 4, so that the measuring device can maintain the size of the elevator installation gap, which is convenient for recording.

[0025] A scale groove 41 is provided at the lower end of both sides of the measuring plate 4. One side of the anti-slip pad 20 abuts against one side of the measuring plate 4. The length of the measuring plate 4 is the same as the length of the driven guide rod 3. The scale groove 41 facilitates the degree of the gap distance for elevator installation.

The length of the stabilizing guide rod 5 is the same as that of the driven guide rod 3. The limiting screw sleeve 13 prevents the driven guide rod 3 from detaching from the fixed plate 1 during the use of the measuring device, facilitates the disassembly and assembly of the entire measuring device, and improves practicality.

[0029] When it is necessary to measure the gap between the elevator car and the elevator shaft wall, the staff holds the handle 9 to make the right-angled side of the first measuring cone block 6 on the fixed plate 1 touch the elevator car wall, and controls the motor 101 to rotate forward by pushing the control button 11. The motor 101 drives the first gear 103 to engage the second gear 105, so that the connecting rod 104 drives the driving gear 106 to engage the teeth 32 on the driven guide rod 3, so as to adjust the position of the movable plate 2, so that the right-angled side of the second measuring cone block 7 touches the elevator shaft wall, so as to record the gap value through the scale line on the measuring plate 4. The reset control button 11 is used to control the motor 101 to reverse, so that the movable plate 2 is reset, which is convenient for the next gap measurement, thereby improving the measurement efficiency. The measuring device is not affected by space when measuring the elevator installation gap, thereby improving practicality.
