Description

Technical Field

[0001] The utility model relates to the technical field of elevator car components, in particular to a buffer device for an elevator. Background Art

[0002] A lift is a vertical lift that is powered by an electric motor and equipped with a box-shaped cabin. It is used to carry people or goods in multi-story buildings. For ease of reading, the elevators mentioned below are all referred to as lifts. The advantage of an elevator is that it is convenient for passengers to go up and down the stairs quickly. In other words, it can quickly change the altitude of the passengers. However, the disadvantage of an elevator is that the excessive vertical acceleration at startup causes some passengers with poor physical fitness to be unable to adapt, and in severe cases, it causes severe dizziness. In order to adapt to passengers, it is not advisable to simply reduce the operating efficiency of the elevator. Especially in large shopping malls with large passenger flow, the elevator needs to run quickly. Therefore, how to reduce the discomfort of passengers while maintaining the efficient operation of the elevator is a problem that needs to be solved in this field.

[0003] According to the "A buffer device for elevators (publication number: CN 217650676U; application number: 202221677157.4)" published on the patent website, the above application optimizes the problem of the comparative case 'A height-adjustable elevator shock-absorbing device with publication number: CN114538251A': "The device for adjusting the height of the top plate and the degree of spring compression is an electric telescopic rod. An electric device is set in the closed space at the bottom of the car. It is very troublesome to power on the electric device, and the electric telescopic rod is kept in a telescopic state for a long time, which will greatly reduce its service life and require frequent maintenance in the future." However, the buffer device in the above application can only be set at the bottom of the elevator shaft when in use, and the buffer effect is limited, which is not convenient to use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The utility model provides a technical solution:

[0025] Embodiment 1

[0026] Combination Figures 1 to 3 A buffer device for an elevator comprises an inner wall 3 of an elevator shaft, a buffer mechanism 1 is arranged on the front side of the inner wall 3 of the elevator shaft, and a connecting mechanism 2 is arranged on the front side of the buffer mechanism 1.

[0027] The buffer mechanism 1 includes a buffer component 11, a sliding component 12 and a limiting component 13. The buffer component 11 is arranged on the front side of the inner wall 3 of the elevator shaft, the sliding component 12 is arranged in the buffer component 11, and the limiting component 13 is arranged on the front side of the inner wall 3 of the elevator shaft.

[0028] The buffer assembly 11 includes a fixed cylinder 1101, which is fixedly connected to the front side of the inner wall 3 of the elevator shaft, a sliding cylinder 1102 is slidably connected to the fixed cylinder 1101, a connecting rod 1103 is fixedly connected to the inner side of the sliding cylinder 1102, and the connecting rod 1103 is slidably connected to the outer side of the fixed cylinder 1101, a compression spring 1104 is fixedly connected to the inner bottom of the fixed cylinder 1101, and the sliding assembly 12 includes a rotating cylinder 1101. Drum 1201, the rotating drum 1201 is rotatably connected to the outer ring of the connecting rod 1103, the rear side of the rotating drum 1201 is fixedly connected with a protrusion 1202, the rear side of the protrusion 1202 is fixedly connected with a limiting slide 1203, the limiting assembly 13 includes a boss 1301, the boss 1301 is fixedly connected to the front side of the inner wall 3 of the elevator shaft, the front side of the boss 1301 is in contact with the rear side of the limiting slide 1203, and the front side of the inner wall 3 of the elevator shaft is provided with an empty groove 1302 below the boss 1301.

[0029] Furthermore: the slides 1102 on the left and right sides always maintain an upward force under the action of the compression springs 1104. When the elevator is moving downward, the transmission plate 1 2101 drives the rotating drum 1201 to move downward under the action of the convex pad 2202, and the upward force generated by the compression springs 1104 on the left and right sides is used to buffer the force of the elevator's descent. The convex frame 1301 fits with the rear side of the limiting slide plate 1203 to limit the limiting slide plate 1203, so that the rotating drum 1201 cannot rotate, thereby increasing the stability of the position of the transmission plate 1 2101. When the rotating drum 1201 moves downward to the front side of the empty slot 1302, the limiting slide plate 1203 loses the limitation of the convex frame 1301, so that the rotating drum 1201 can rotate under the action of the transmission plate 1 2101, so that the elevator will not be obstructed in the downward process. At the same time, the buffer structure can be repeatedly arranged in the inner wall 3 of the elevator shaft, and the buffering effect of the elevator descent can be improved by increasing the number, which is highly practical.

[0030] Embodiment 2

[0031] See also Figure 1 , Figure 3 and Figure 4On the basis of the first embodiment, it is further obtained that the docking mechanism 2 includes a transmission component 21 and a docking component 22 , the transmission component 21 is arranged on the front side of the sliding component 12 , and the docking component 22 is arranged above the transmission component 21 .

[0032] The transmission assembly 21 includes a transmission plate 2101, which is fixedly connected to the front side of the rotating drum 1201, and a convex pad 2102 is fixedly connected to the top of the transmission plate 2101. The connecting assembly 22 includes a transmission plate 2201, which is arranged above the transmission plate 2101, and a convex pad 2202 is fixedly connected to the bottom of the transmission plate 2201, and a fixing frame 2203 is fixedly connected to the front side of the transmission plate 2201.

[0033] Furthermore, the staff only needs to fix the second transmission plate 2201 on both sides of the bottom of the elevator corresponding to the position of the first transmission plate 2101, so that the elevator can contact with multiple first transmission plates 2101 during the descent process to complete the buffering of the elevator, thereby increasing the stability of the elevator during the descent process.

[0034] In actual operation, when the device is used, the elevator moves downward and drives the second transmission plate 2201 downward through the fixed frame 2203, and the second transmission plate 2201 moves downward and contacts the first transmission plate 2101, driving the first transmission plate 2101 downward, and the first transmission plate 2101 moves downward and drives the connecting rod 1103 downward through the rotating drum 1201, and the connecting rod 1103 moves downward and drives the compression spring 1104 downward through the sliding drum 1102, and the compression spring 1104 is compressed downward to generate an upward rebound force to the elevator downward. The downward force is consumed, and at the same time, the limiting slide plate 1203 is driven to move downward by the convex block 1202 during the downward movement of the rotating drum 1201. When the limiting slide plate 1203 moves to the front side of the empty slot 1302, the limiting slide plate 1203 loses the limit of the convex frame 1301. At this time, the transmission plate 1 2101 is driven by the downward pressure of the transmission plate 2 2201 to drive the rotating drum 1201 to rotate around the connecting rod 1103 as the axis. At this time, the transmission plate 1 2101 releases the limit of the transmission plate 2 2201, and then the elevator can continue to move downward;

[0035] At the same time, after the elevator moves downward and breaks away from the contact with the buffer structure, the slide 1102 drives the connecting rod 1103 to move upward under the action of the compression spring 1104, and the connecting rod 1103 moves upward to drive the rotating drum 1201 to move upward. When the rotating drum 1201 moves upward, it drives the limiting slide 1203 to move upward, and the limiting slide 1203 moves upward and contacts with the cam 1301, so that the rear side of the limiting slide 1203 fits with the cam 1301, and after the rear side of the limiting slide 1203 fits with the front side of the cam 1301, the transfer plate 2101 rotates upward and remains straight and upward until the slide 1102 moves upward to the top, at which time the resetting work of the transfer plate 2101 is completed.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
