Description

Technical Field

[0001] This invention relates to the field of elevator landing door lock detection, and specifically to a device for rapid inspection of landing door locks. Background Technology

[0002] like Figure 1 As shown, the elevator landing door lock includes: a mounting base 11, a rotating arm 12, a rotating wheel 13, a fixed base 14, a pull rope 15, a spring 16, and a mechanical drive mechanism (not shown in the figure). The landing door is connected to the first end of the mechanical drive mechanism, the second end of the mechanical drive mechanism is connected to one end of the pull rope 15, and the other end of the pull rope 15 is connected to the rotating arm 12. The first end of the rotating wheel 13 is equipped with a rotatable rotating wheel 13, and the pull rope 15 passes around the rotating wheel 13. The first end of the rotating arm 12 is rotatably mounted on the mounting base 11. The mounting base 11 is mounted on the top of the landing door frame 6. A fixed base 14 is mounted on the mounting base 11. The fixed base 14 can make electrical contact with the second end of the rotating arm 12 after closing. The fixed base 14 has a certain elasticity to maintain the tightness between the fixed base 14 and the second end of the rotating arm 12. A spring 16 is installed between the rotating arm 12 and the mounting base 11. The elasticity is used to keep the second end of the rotating arm 12 and the fixed base 14 in a closed state. In elevator maintenance, it is necessary to check the position of the first end of the rotating arm 12 in the elevator landing door lock to check whether the rotating arm 12 is installed in place. However, in the existing technology, it is necessary to check whether the first end of the rotating arm 12 is installed in place layer by layer, which makes elevator maintenance very difficult. Summary of the Invention

[0003] The present invention provides a device for quick inspection of door locks, which solves the problem in the prior art that the first end of the rotating arm can only be checked manually layer by layer to see if it is installed in place.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses a device for quick inspection of landing door locks, comprising: a mounting frame, a first-side detection mechanism, a second-side detection mechanism, and a control module. The mounting frame is installed on the top of the elevator car, and an opening is formed at the end of the mounting frame away from the elevator car, allowing the rotating wheel in the elevator landing door lock to move up and down relative to the mounting frame. The first-side detection mechanism and the second-side detection mechanism are mounted on the mounting frame. The first-side detection mechanism is used to detect the first-side position of the rotating wheel in the elevator landing door lock, and the second-side detection mechanism is used to detect the second-side position of the rotating wheel in the elevator landing door lock. The output end of the first-side detection mechanism is connected to the first input end of the control module, and the output end of the second-side detection mechanism is connected to the second input end of the control module.

[0005] Preferably, the elevator landing door lock includes a pull rope and a rotating arm. The rotating arm is surrounded by the pull rope, which includes a flexible rope and a rigid spiral arm. One end of the rigid spiral arm is fixed to the rotating arm in the elevator landing door lock by a fixing pin, and the other end of the rigid spiral arm is connected to the flexible rope. Preferably, a positioning detection mechanism is installed on the mounting frame. The positioning detection mechanism is used to detect whether the elevator landing door lock disengages as the landing door opens by sensing the large end of the fixing pin.

[0006] Preferably, the positioning detection mechanism and the mounting bracket are positioned by a position adjustment mechanism, which is used to adjust the movement of the positioning detection mechanism away from or towards the large end of the fixed pin.

[0007] Preferably, the first-side detection mechanism, the second-side detection mechanism, and the positioning detection mechanism all include: a sensing part, a sensing switch, and a power supply. The output end of the power supply supplies power to the first end of the sensing switch, and the second end of the sensing switch is the output end of the first-side detection mechanism, the second-side detection mechanism, or the positioning detection mechanism. The pressing part of the sensing switch is equipped with a sensing part, which is used to be pressed by a rotating wheel or by the large end of a fixing pin.

[0008] Preferably, the sensing part includes a contact section and a bending section. The contact section is connected to the pressing part of the inductive switch, and the bending section is connected to the contact section. The bending section is located above the contact section and extends in a direction away from the rotating wheel or the fixing pin.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] After prolonged use, elevators are prone to issues such as the first end of the rotating arm in the landing door lock becoming loose, or improper installation. This can prevent the second end of the rotating arm from closing with the fixed seat, thus preventing the landing door lock from disengaging when the door opens and failing to detect the door's status. Therefore, this application designs a device for quickly checking the landing door lock. This device is used to detect the accuracy of the position of the first end of the rotating arm in the elevator landing door lock. When the second end of the rotating arm cannot close with the fixed seat, it mainly indicates that the first end of the rotating arm is moving left and right. Therefore, the device includes a first-side detection mechanism and a second-side detection mechanism. The first-side detection mechanism senses the left side of the rotating wheel in the device, and the second-side detection mechanism senses the right side of the rotating wheel. The rotating wheel is located at the first end of the rotating arm, and the first end of the rotating arm rotates around the axis of the rotating wheel. Therefore, the position of the rotating wheel reflects the position of the first end of the rotating arm. Then, a design was developed in which both the first and second side detection mechanisms are mounted on a mounting frame. These mechanisms, mounted on the frame, can move with the elevator car to the door locks of different floors. The opening design allows the rotating wheels to have sufficient space relative to the frame during its movement, preventing them from obstructing the frame's movement. Furthermore, the first and second side detection mechanisms are located on the left and right sides of the rotating wheels, respectively, ensuring they are not obstructed during movement. This allows a single mounting frame, first and second side detection mechanisms to perform door lock checks on every floor, reducing the need for separate first and second side detection mechanisms and lowering costs. The system enables rapid detection by moving the elevator car from the lowest to the highest floor, thus avoiding the need for manual checks that would otherwise lead to low elevator maintenance efficiency.

[0011] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, achieved objectives, and functions of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Figures 2 to 5 As shown, the present invention discloses a device for quick inspection of landing door locks, comprising: a mounting frame 2, a first-side detection mechanism 3, a second-side detection mechanism 4, and a control module (not shown in the figure). The mounting frame 2 is installed on the top of the elevator car 5, and an opening is formed at the end of the mounting frame 2 away from the elevator car 5. The opening allows the rotating wheel 13 in the elevator landing door lock to move up and down relative to the mounting frame 2. The first-side detection mechanism 3 and the second-side detection mechanism 4 are installed on the mounting frame 2. The first-side detection mechanism 3 is used to detect the first-side position of the rotating wheel 13 in the elevator landing door lock, and the second-side detection mechanism 4 is used to detect the second-side position of the rotating wheel 13 in the elevator landing door lock. The output end of the first-side detection mechanism 3 is connected to the first input end of the control module, and the output end of the second-side detection mechanism 4 is connected to the second input end of the control module.

[0019] Preferably, the elevator landing door lock includes a pull rope 15 and a rotating arm 12. A rotating wheel 13 is surrounded by the pull rope 15. The pull rope 15 includes a flexible rope and a rigid wrapping arm. One end of the rigid wrapping arm is fixed to the rotating arm 12 in the elevator landing door lock via a fixing pin 17, and the other end of the rigid wrapping arm is connected to the flexible rope. To enable the pull rope 15 to rotate the rotating arm 12, the rigid wrapping arm is wrapped around the rotating wheel 13. When the landing door opens, an external mechanical mechanism pulls the flexible rope downwards, thereby pulling the rigid wrapping arm to rotate the rotating arm 12. The second end of the rotating arm 12 separates from the fixing seat 14, thus disengaging. Preferably, a positioning detection mechanism 7 is installed on the mounting bracket 2. The positioning detection mechanism 7 is used to detect whether the elevator landing door lock disengages as the landing door opens by sensing the large end of the fixing pin 17. Since the rotating arm 12 needs to rotate to the open position when the landing door opens, a positioning detection mechanism 7 is also designed to detect whether the rotating arm 12 is driven to the disengaged position.

[0020] The elevator system operates as follows: First, the elevator car 5 rises and falls to the landing door and the elevator landing door lock; then, the elevator car 5 door drives the landing door to open, and at the same time, the elevator landing door lock is driven by the landing door to the state where the second end of the rotating arm 12 is separated from the fixed seat 14.

[0021] When the elevator landing door lock is in the closed state, the fixing pin 17 can be located to the left of the rotating wheel 13 or above the rotating wheel 13.

[0022] When the fixed pin 17 is located to the left of the rotating wheel 13, the arrival detection mechanism 7 is pressed into a closed position as the elevator car 5 rises to the corresponding floor. When the landing door opens, the rotating arm 12 is driven to rotate, and the rotating arm 12 drives the fixed pin 17 to rotate away from the arrival detection mechanism 7. The arrival detection mechanism 7 then disconnects. By checking whether the arrival detection mechanism 7 is pressed into a closed position by the large end of the fixed pin 17 on the rotating arm 12, it can be determined whether the rotating arm 12 has rotated from the closed position to the open position. This achieves the detection of the elevator landing door lock and improves the efficiency of elevator landing door lock detection.

[0023] Preferably, the positioning detection mechanism 7 and the mounting bracket 2 are positioned by a position adjustment mechanism, which is used to adjust the movement of the positioning detection mechanism 7 away from or towards the large end of the fixed pin 17.

[0024] Preferably, the first side detection mechanism 3, the second side detection mechanism 4, and the positioning detection mechanism 7 each include: a sensing part 31, a sensing switch 32, and a power supply. The output end of the power supply supplies power to the first end of the sensing switch 32, and the second end of the sensing switch 32 is the output end of the first side detection mechanism 3, the second side detection mechanism 4, or the positioning detection mechanism 7. The pressing part of the sensing switch 32 is equipped with the sensing part 31, which is used to be pressed by the rotating wheel 13 or the large end of the fixing pin 17.

[0025] Preferably, the sensing part 31 includes a contact section 311 and a bending section 312. The contact section 311 is connected to the pressing part of the sensing switch 32. The contact section 311 is connected to the bending section 312, which is located above the contact section 311 and extends away from the rotating wheel 13 or the fixing pin 17.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
