Description

Technical Field

[0001] The utility model relates to the field of elevator car door opening and closing technology, in particular to an elevator car door opening guide structure based on spring compensation. Background Art

[0002] The opening and closing process of the elevator car door is that the motor transmits power to the door wheel through the gear transmission system, so that the door leaf moves along the guide rail. During the movement of the door, the safety device will monitor the situation around the door leaf to ensure that there are no obstacles. At the same time, the door lock can ensure that the door leaf is firmly locked when closed to prevent the door leaf from opening accidentally.

[0003] However, as the elevator is used, it may sometimes jerk when opening or closing the door. The reason for the jerk is that the car door transmission system is located above the elevator car and is not connected to the car door, and there is no effective guidance and support under the car door, which sometimes causes the elevator to jerk when opening or closing the door.

[0023] Reference Figure 1-4As shown, the elevator car door opening guide structure based on spring compensation includes a car 1 and a bracket 2 arranged on the lower end surface of the car 1. The bracket 2 and the opposite surface of the car 1 are provided with a linkage component 3. The linkage component 3 includes a moving block 33 located between the bracket 2 and the car 1, and a placement opening 34 opened on the surface wall of the moving block 33 and connected to the outside on both sides. A circular wheel 37 that can contact the inner wall of the elevator shaft is provided in the placement opening 34. The elevator shaft is generally square, but there is a gap between the elevator and the elevator shaft to facilitate elevator maintenance. In particular, at the elevator exit of each floor, a gap is generally left so that some waste brought by users using the elevator can fall into the elevator shaft instead of being stuck between the elevator and the elevator shaft, thereby affecting the use of the elevator. At this time, if a gap is provided in the lower half of the elevator car door The wheels that fit at the exit of the elevator shaft need to be tightly fitted with the elevator shaft or moved to the exit of the elevator shaft to ensure that there will be no setbacks when the elevator car door moves. However, the wheels move left and right, and the elevator moves up and down. When the wheels are tightly fitted with the exit of the elevator shaft, it will affect the movement of the elevator. For this reason, a moving block 33 that can be fixed to the elevator car door is provided between the car 1 and the bracket 1. A placement opening 34 is also provided on the opposite sides of the two moving blocks 33. A movable round wheel 37 is provided in the placement opening 34. The round wheel 37 pops out after the elevator car door is opened and fits tightly with the exit of the elevator shaft, and retracts as the elevator car door is closed, so that the upper and lower parts of the elevator car door move in unison without affecting the up and down movement of the elevator. A pushing component 5 is also provided on the linkage component 3.

[0024] The linkage assembly 3 also includes a slide groove 31 provided on the opposite side of the bracket 2 and the car 1, and a slider 32 with an end face connected to the moving block 33 is slidably connected in the slide groove 31. The slider 32 and the moving block 33 are fixed to the elevator car door, and the slider 32 is slidably connected in the slide groove 31, so that the moving block 33 moves more smoothly with the elevator car door. A sliding assembly 4 is also provided in the placement port 34, and the sliding assembly 4 includes a moving groove 41 provided on the upper and lower end faces of the placement port 34, and a sliding block 42 is slidably connected in the moving groove 41. An elastic rope 43 is provided on one side of the sliding block 42 at one end connected to the inner wall of the moving groove 41. The linkage assembly 3 also includes a moving plate 35 connected to the sliding block 42, and a rotating shaft is provided between the two moving plates 35. Rod 36, rotating rod 36 passes through the round wheel 37. When the two moving blocks 33 move in opposite directions with the two elevator car doors, the rotating rod 36 fixed on the moving plate 35 by bearings and the round wheel 37 fixed on the rotating rod 36 need to be pushed out to fit tightly against the inner wall of the elevator entrance and exit. When the elevator car door is closed, the moving plate 35 needs to be recovered. For this purpose, moving grooves 41 are provided on the upper and lower end walls of the placement opening 34. The sliding block 42 is slidably connected in the moving groove 41. The sliding block 42 is fixed to the moving plate 35, and an elastic rope 43 is fixed between the sliding block 42 and the moving groove 41, so that after the elevator car door is closed, the elastic rope 43 can pull the moving plate 35 to reset through elastic reset, thereby allowing the round wheel 37 to re-enter the development inner purchase meeting opening 34.

[0025] The pushing component 5 includes a slot 51 provided in the moving block 33, a compression spring 52 is provided in the slot 51, one end of the compression spring 52 is connected to the moving block 33 with one end extending to the outside, an extrusion groove 54 is provided on one side of the moving block 33, an extrusion block 55 with one end extending to the placement port 34 is inserted in the extrusion groove 54, and the inner wall of the moving block 33 is further provided with one end communicating with the slot 51 and the other end communicating with a hole for the extrusion block 55 to move, and a limiting groove 58 for the extrusion strip 57 to be inserted on one side of the extrusion block 55. In order to ensure that the moving plate 35 can be pushed out after the elevator car door is opened, the compression spring 52 is fixed at the tail end of the inner cavity of the slot 51 provided on the moving block 33, and the compression spring 52 fixes the extension block 53. When the elevator car door is opened, the extension Due to the lack of extrusion, the block 53 pops out under the elastic reset of the compression spring 52. Since an extrusion groove 54 is provided on one side of the extension block 53 and an extrusion block 55 is inserted in the extrusion groove 54, one end of the extrusion block 55 extends into the placement port 34 and is fixed to the movable plate 35, so that the pop-up extension block 53 will squeeze the extrusion block 55 and push it out, thereby pushing the movable plate 35 out. After being pushed out, in order to ensure that the movable block 35 will not be squeezed and reset before the elevator car door is closed, an extension groove 56 is provided on the movable block 33 and connected to the slot 51. An extrusion strip 57 with one end fixed to the extension block 53 is inserted in the extension groove 56, and the extrusion strip 57 can be inserted into the limiting groove 58 provided on one side of the refueling block 55, thereby limiting the extended extrusion block 55.

[0026] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
