[0002] Elevators are auxiliary tools for going up and down in high-rise buildings. In order to ensure the long-term and effective operation of the elevator, it is necessary to jack up the elevator car and the running power components for inspection and maintenance. During the maintenance operation, the car slowly descends to the appropriate position and then opens the hall door, so as to climb onto the top of the car for maintenance work. When the existing elevators are repaired, they are generally controlled to stop the elevator through the elevator's microcomputer control system, and then the maintenance personnel repair the elevator.

[0003] In the prior art, the method of controlling the elevator to stop by the elevator microcomputer control system during elevator maintenance has defects. If the elevator fails, it does not have a safety locking function. Once the control system is misaligned, the elevator will fall while running, causing personal injury to maintenance personnel. Therefore, it is proposed to use a safety pin to achieve locking and positioning between the elevator and the track during elevator maintenance. However, the single layer of protection is weak, and it is easy for the safety pin to fail to lock normally due to operational reasons or other reasons.

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1 and Figure 2 The utility model provides an elevator car locking support device, which includes a fixed frame 1 installed on one of its matching devices, a blocking member 2 movably installed on the fixed frame, and a first matching structure 3 arranged on another matching device and matching with the blocking member 2; wherein the two sets of matching devices are respectively an elevator frame and an elevator guide rail matching therewith; in the present embodiment, the fixed frame 1 is fixedly installed on the elevator frame, and the first matching structure 3 is arranged on the elevator guide rail. Of course, the installation positions can also be interchanged (the fixed frame 1 is installed on the elevator guide rail).

[0024] In this embodiment, the first matching structure is at least one group of first positioning holes 10 arranged along a predetermined direction; the blocking member 2 partially extends into the matching structure after being moved, and the two cooperate to block the relative movement of the two groups of matching devices, that is, the elevator frame moves relative to the elevator guide rail. As shown in the figure, the first positioning holes 10 are arranged along the direction of the elevator guide rail. The first positioning hole 10 corresponds to the blocking member 2 structure as a non-opening structure, that is, an inner hole structure, and the matching blocking member 2 is a pin structure, which is inserted into the first matching structure by moving along its own axis. When in the working state, the blocking member 2 moves and is inserted into one of the first positioning holes 10 to realize the positioning of the elevator guide rail and the elevator frame.

[0025] The first positioning hole 10 may also be an open structure corresponding to the structure of the blocking member 2 ( Figure 5 As shown), it has an opening for the blocking member 2 to enter the interior thereof, and the matching blocking member 2 is a "" or "[" type pin structure ( Figure 4 When in working state, the upper or lower working end of the rotating blocking member 2 is moved into the first positioning hole 10 by changing the direction to realize the positioning of the elevator guide rail and the elevator frame.

[0026] In this embodiment, the blocking member 2 is driven by hand, and the blocking member 2 is provided with a lever 21 as a driving part and having a predetermined angle (vertical as shown in the figure) with the axis of the blocking member 2. In addition, the fixing frame 1 is provided with a guide rail 5 for the lever to pass through; the guide rail 5 has at least one set of blocking positioning parts 51 perpendicular to the extension direction of the blocking member 2. For example, as shown in the figure, the guide rail 5 is a horizontal "["-shaped structure, and after the lever moves to the blocking positioning part 51, the movement of the blocking member 2 is stopped (the lever is blocked by the blocking positioning part 51 to achieve the limit position).

[0027] See also Figure 2 and Figure 3 The fixing frame 1 is also provided with a locker for locking the active state of the blocking member 2.

[0028] A second matching structure is provided at a predetermined position of the blocking member 2. The output end of the lock can be movable and extend into the second matching structure 4 after being movable to lock the movable state of the blocking member 2. By locking the above structure, double locking (double insurance) of the locking structure is achieved, thereby increasing the safety of the operator. Specifically, the output end moves along its own axis and enters the second matching structure. The second matching structure is a second positioning hole or positioning groove (such as Figure 1 , 2 Positioning groove shown), Figure 3 shown.

[0029] Preferably, the second matching structure is a second positioning hole. When the lever moves to the bottom of the blocking positioning portion 51, the axis of the second positioning hole coincides with the axis of the output end of the lock. Through the above arrangement, the working condition feedback of the lever can be realized through the lock. If the lever does not move to the bottom of the blocking positioning portion 51 when locked, the axis of the second positioning hole coincides with the axis of the output end of the lock, that is, the output end of the lock cannot be extended into the second positioning hole, so that it cannot be fully extended. At this time, the lock triggers the alarm. Through the above feedback, it is ensured that the lever is in the best limit position when locked, and the stability of the equipment during operation is ensured.

[0030] In summary, the utility model provides an elevator car locking support device, including a fixed frame installed on one of its matching devices, a blocking member movably installed on the fixed frame, and a first matching structure arranged on another matching device and matched with the blocking member; wherein the two groups of matching devices are respectively an elevator frame and an elevator guide rail matched therewith; the fixed frame is fixedly installed on the elevator frame, and the first matching structure is arranged on the elevator guide rail. Of course, the installation positions can also be interchanged (the fixed frame is installed on the elevator guide rail). The first matching structure is at least one group of first positioning holes arranged along a predetermined direction; the blocking member after the movement partially extends into the matching structure, and the two cooperate to block the relative movement of the two groups of matching devices, that is, the elevator frame moves relative to the elevator guide rail. As shown in the figure, the first positioning hole is arranged with a plurality of first positioning holes along the direction of the elevator guide rail. The first positioning hole corresponds to the blocking member structure as a non-opening structure, that is, an inner hole structure, and the matching blocking member is a pin structure, which is inserted into the first matching structure by moving along its own axis. When in working state, the blocking member moves and is inserted into one of the first positioning holes to realize the positioning of the elevator guide rail and the elevator frame. This device is a device for safety protection in the elevator shaft, which has the advantages of double insurance, good versatility, and easy operation and use. It is suitable for use when repairing the elevator main engine in a machine roomless elevator, which improves safety and plays a role in perfect safety protection. As a solid structure, the protection box body plays a role of clamping and fixing in mechanical function, avoiding displacement of the elevator car and the problem of pulley in the absence of power. In addition, the function of the safety switch is to disconnect the safe operation circuit of the elevator to prevent it from running automatically.
