Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. For the sake of clarity and brevity, actual embodiments are not limited to the features described in this specification. The present example is carried out on the premise of the technical scheme of the invention, and a detailed implementation is given, but the protection scope of the present invention includes but is not limited to the following examples.
Referring to fig. 1, there is shown a perspective view of the movable stop for an elevator system of the present invention fully extended, i.e., in service condition.
The movable stop means comprise a seat 9. The base 9 is connected to the first damper 1 in one direction by a first damper stay 2 and to the second damper 8 in the other direction by a second damper stay 14.
In this embodiment, the two directions are preferably perpendicular to each other, and in practical applications, one direction is set to be horizontal and the other direction is set to be vertical.
In this embodiment, the first and second bumper stays 2, 14 are preferably different lengths. The length of the first damper strut 2 should be selected such that: the length of the first bumper stay 2 is such that when the movable stop device is in an inspection state, i.e. when the first bumper stay 2 is in a vertical position in this embodiment, the height of the first bumper 1 to the base 9 is a first height, which is required to meet a safe inspection height and space. The length of the second bumper strut 14 should be selected such that: the length of the second buffer stay 8 is a second height when the movable stopping device is not in a maintenance state, i.e. when the elevator is in normal operation, i.e. when the second buffer stay 2 is in a vertical position in this embodiment, the height from the second buffer stay 8 to the base 9 is a second height, which does not need to affect the normal operation of the elevator.
It will be appreciated that in other embodiments of the invention, the above selection criteria for the lengths of the first and second shock absorber struts 2, 14 may be interchanged.
A rotating shaft hole (not numbered) is opened in the base 9, and a round angle R concentric with the rotating shaft hole is provided. A fixed rotating shaft 10 penetrates through the rotating shaft hole, and the base 9 can rotate around the rotating shaft 10 along the round angle R when being driven.
The base 9 is connected with the motor 6 through the transmission mechanism 7 on one side, and when the motor 6 rotates, the base 9 is driven to rotate around the rotating shaft 10 through the transmission mechanism 7. The transmission mechanism 7 is preferably a gear transmission mechanism, and comprises a pinion connected with the motor 6 and a gearwheel connected with the base 9, and the pinion and the gearwheel are matched with each other to enable the gear transmission mechanism to reduce the rotating speed of the motor 6 and increase the torque output to the base 9.
The motor 6 drives the base 9 to rotate in the direction of the arrow in the figure through the transmission mechanism 7, so as to drive the first buffer stay 2 and the second buffer stay 14 connected with the base 9 to rotate, so that the movable stop device for the elevator system has two states: when the first buffer 1 is positioned right above, namely the first buffer support rod 2 is positioned at the vertical position, the movable stop device for the elevator system is in a maintenance state; when the second buffer 8 is directly above, i.e. the second buffer stay 14 is in the vertical position, the movable stop arrangement for the elevator system of the invention is in a non-service state, i.e. the elevator is in a normal operating state. Referring to fig. 2, there is shown a perspective view of the movable stop for an elevator system of the present invention fully retracted, i.e., in a non-service condition for normal elevator operation.
The movable stop device for an elevator system of the present invention further comprises a diagonal stay 3 for supporting the first buffer stay 2. One end of the inclined strut 3 is fixedly connected to the first buffer strut 2, and the other end of the inclined strut is fixedly connected to a sliding block 4, and the sliding block 4 can slide on a sliding rail 5. When the first buffer stay bar 2 rotates under the action of the motor 6, one end of the inclined stay bar 3 connected with the sliding block 4 slides along the sliding rail 5 along with the sliding block 4. The first damper stay 2 may be provided with a plurality of openings in the length direction, and the openings are connected to the diagonal stays 3 having different lengths.
In the present embodiment, the length of the first buffer stay 2 is fixed, but it is understood that in other embodiments, in order to flexibly adapt to the depth of the pit bottom of different elevator systems, the first buffer stay 2 may be adjustable or telescopic, for example, the first buffer stay 2 may be provided in multiple pieces or segments, and the appropriate pieces or segments may be connected and fixed through the opening formed therein as required, for example, the first buffer stay 2 is connected and fixed, so as to obtain the first buffer stay 2 with different lengths. Similarly, the second bumper stay 14 may be adjustable or retractable as well.
The movable stopping device for the elevator system also comprises a bottom box 13, and the base 9, the motor 6 and the sliding rail 5 are arranged in the bottom box 13. The bottom case 13 is made of corrosion-resistant material, and has no holes or gaps at the bottom and around, and has a certain height around. When the bottom box 13 is arranged in a pit of an elevator system, the bottom box can play a role of preventing water for components arranged in the bottom box.
A first switch 11 and a second switch 12 are provided at appropriate positions of the base 9 or the back box 13. When the first buffer 1 is rotated to the right above, the first buffer support rod 2, the second buffer support rod 8, the inclined support rod 3 or the sliding block 4 is enabled to touch and press the first switch 11, so that the first switch 11 is closed, and a closed signal is transmitted to a control system of an elevator to inform the control system that the movable stop device for the elevator system is in a maintenance state. When the second buffer 8 is rotated to the right above, the first buffer support rod 2, the second buffer support rod 8, the inclined support rod 3 or the sliding block 4 is enabled to touch and press the second switch 12, so that the second switch 12 is closed, and a closed signal is transmitted to a control system of the elevator to inform the control system that the movable stop device for the elevator system is in a non-maintenance state, namely the elevator system is in a normal operation state.
When the movable stop device for the elevator system is arranged below the elevator car, the elevator car can be ensured not to collide with the ground during operation, and enough ground-off maintenance space is provided during pit maintenance, so that the standard requirement of a shallow pit elevator is met; when the movable stopping device for the elevator system is arranged below the counterweight, the elevator car can reach the top floor during normal operation, and meanwhile, enough top floor space is reserved during maintenance on the top of the elevator car, so that the building requirements on an elevator shaft are reduced, and the safety of maintenance personnel is guaranteed.
The above description is not intended to limit the present invention strictly, as the preferred embodiment of the present invention. Any modification, equivalent replacement or improvement made by those skilled in the art within the spirit and principle of the present invention should be included in the protection scope of the present invention.
