Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
First embodiment, as shown in fig. 1, a shock absorbing device for an elevator comprises a vertical buffer unit 1 for supporting upward when an elevator car falls, a base unit 2 for mounting the vertical buffer unit 1, an elastic member unit 3 provided on the base unit 2 and supporting the vertical buffer unit 1, and a lateral buffer unit 4 provided on the base unit 2 and serving as a stopper when the vertical buffer unit 1 falls.
When the vertical buffer member unit 1 is subjected to impact force from the falling of the elevator car, the vertical buffer member unit not only can move downwards, but also has shaking force in the horizontal direction, and the transverse buffer member units 4 are positioned on the left side and the right side of the vertical buffer member unit 1, so that the effect of balancing the vertical buffer member unit 1 is achieved by utilizing the shock absorption capacity of the transverse buffer member units, and the buffering process of the transverse buffer member units is more stable.
In addition, the inventor has noticed that, because the vertical buffer unit 1 absorbs too much impact force from the elevator car during the buffering process, a vertical shearing force is generated to the horizontal buffer unit 4, and the shearing force causes the horizontal buffer unit 4 to bend after long-time operation, thereby losing the buffering function. Then, in order to protect the lateral buffer member unit 4, as shown in fig. 2 and 3, a stabilizing block unit 5 is additionally provided in the base unit 2 for mounting the lateral buffer member unit 4, for supporting the lateral buffer member unit 4 to protect it.
The inventor will further describe the functional implementation of each unit.
< about the vertical cushion unit 1>
The vertical buffer unit 1 mainly comprises a support plate 101 and a support column 102, when the car falls, the support plate 101 jacks up the car upwards to support the car, and the support column 102 is arranged in a support column groove 202 on a base block 201 to guide the support plate 101 to move vertically, so that when the support plate 101 buffers and resists the downward gravity of the car, the upward supporting force of the support plate is always located on the same vertical line with the gravity.
The buffering force of the supporting plate 101 is mainly realized by an upper buffering spring 301 sleeved on the supporting column 102 and a lower buffering spring 302 positioned in the supporting column groove 202, and the materials of the springs are selected to meet the basic requirement of car buffering. The inventor notices that the single spring buffer device can make the stress of the support plate 101 unstable during falling and generate the left-right deviation phenomenon, and after the springs are arranged up and down simultaneously, the deviation phenomenon can be greatly weakened.
It should be noted that the spring installation process is completed by first installing the lower cushion spring 302 into the support post groove 202, then sleeving the upper cushion spring 301 on the support post 102, and finally inserting the support post 102 into the support post groove 202, and thereafter, by installing a limiting device such as a self-tapping screw at the opening of the support post groove 202, the support post 102 can be prevented from being ejected out of the support post groove 202 by the lower cushion spring 302.
< about lateral cushion unit 4>
During the falling process of the supporting column 102, an undesired horizontal turbulence phenomenon occurs, which in turn causes friction to the inner wall of the supporting column groove 202, and the friction force is transmitted to the supporting plate 101 through the supporting column 102, so that the buffering process is not linear enough. In addition, the high friction force causes the inner groove wall to generate fine damage, and in turn, the friction force is increased again to form vicious circle. After long-term use, the small damage also forms a larger groove, so that the supporting column 102 is directly clamped into the groove on the inner wall of the supporting column groove 202 in the falling process, and the damping effect of the device is completely lost.
In order to solve the above problem, the inventor has provided a transverse groove 203 on each side of the support column groove 202, and provided a transverse buffer unit 4 in the transverse groove 203, so that the support column 102 falls along a straight line during the falling process by using the jacking action of the transverse buffer units 4 on both sides, thereby avoiding the vibration in the horizontal direction.
As shown in fig. 6, the main body of the lateral buffer member unit 4 is a fixing rod 401 and is provided with a movable groove 406 in the utilization, and is sleeved on the fixing rod 401, and the outer end of the main body is used for engaging with the movable rod 402 of the arc surface deceleration groove 103, and the fixing rod is sleeved with a movable rod return spring 404, and the movable rod 402 is provided with a pushing block 403, and the pushing block 403 transmits pushing force to the movable rod 402 under the pushing action of the movable rod return spring 404, so that the outer end of the movable rod 402 always jacks up the side of the supporting column 102, and the effect of stabilizing the horizontal vibration of the movable rod 402 is achieved.
Further, the inventors found that, when the support column 102 is just subjected to an impact force from the car, the support column 102 descends at an excessively high speed due to the inertia of the car, which may cause damage to the upper buffer spring 301 and the lower buffer spring 302, and therefore the inventors wish to impart a greater resistance to the support column 102 at the initial stage of buffering, thereby protecting the springs. The inventor realizes that as shown in fig. 2 and 3, a spherical engaging block 405 is arranged at the end of the outer end of the movable rod 402, the spherical engaging block 405 is engaged with the arc-shaped deceleration slot 103 arranged at the side of the supporting column 102, when the supporting column 102 descends, the spherical engaging block 405 is engaged with and disengaged from the arc-shaped deceleration slot 103, and the acting force generated in the engaging and disengaging process has the effect of decelerating the supporting column 102.
< with respect to the stabilization block unit 5>
In order to reduce the shearing force to the movable rod 402 when the arc deceleration groove 103 moves downwards, the inventor additionally arranges a stabilizing block unit 5 below the movable rod 402 for always giving supporting force below the movable rod 402 in the moving process, and the specific implementation manner is as follows:
as shown in fig. 4 and 5, an inner sliding groove 204 is provided on the lower groove wall of the transverse groove 203, the stabilizing block unit 5 is provided therein, the main element of the stabilizing block unit 5 for realizing the function is a stabilizing block 501 for supporting the movable rod 402 upwards, two stabilizing block through holes 502 are provided on the stabilizing block 501, the stabilizing block 501 is fixed in the inner sliding groove 204 by inserting a guide post 503, the stabilizing block 501 is pushed by the pushing block 403 when the movable rod 402 moves, and moves together with the movable rod 402, so as to realize the permanent support of the movable rod 402. After the movable rod 402 retracts into the transverse slot 203, the stabilizing block 501 is tightly attached to the pushing block 403 under the action of a stabilizing block return spring 504 between the two guide posts 503, and is returned together with the movable rod 402, so that the supporting effect on the movable rod 402 is realized.
