[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1As shown, an embodiment of this application provides an elevator upper sill door lock gap detection device, including a conveying mechanism 1 for conveying the upper sill 7 and a detection mechanism for detecting the door lock of the upper sill 7. The detection mechanism is located on one side of the conveying mechanism 1. The detection mechanism includes a detection frame 2, a detection fixture 3 for positioning the upper sill 7, two symmetrically arranged counterweight components 4, a drive component 5 for driving the door lock of the upper sill 7, and a camera component 6 for visually detecting the door lock. The detection fixture 3 is vertically installed on the side of the detection frame 2, and the counterweight components 4 are engaged with the door head.

[0022] like Figure 2 As shown, the driving assembly 5 includes a lifting assembly 51, a first clamping assembly 52, and a second clamping assembly 53. The driving end of the lifting assembly 51 is connected to the first clamping assembly 52, and the driving end of the first clamping assembly 52 is connected to the second clamping assembly 53. The lifting assembly 51 is used to drive the first clamping assembly 52 and the second clamping assembly 53 to move upward on both sides of the two pulleys of the door lock latch 71. The second clamping assembly 53 is used to drive the pulleys to open the door lock latch 71, and the first clamping assembly 52 is used to drive the hanging plate to move the door lock latch 71.

[0023] Specifically, when the conveying mechanism 1 transports the elevator sill 7 to one side of the testing fixture 3, the operator pushes the elevator sill 7 into the testing fixture 3. The positioning pin 32 and the electromagnet 33 of the testing fixture 3 position and hold the elevator sill 7 in place. Then, the two counterweight components 4 are installed on the two hanging plates to keep the sill 7 balanced. After the upper sill 7 is fixed in place, the lifting component 51 of the drive assembly 5 drives the first clamping component 52 and the second clamping component 53 to move upward, so that the second clamping plate 532 is located on one side of the pulley of the latch 71, and the first clamping plate 523 is on the other side of the pulley. The second linear module 531 of the second clamping component 53 drives the first clamping plate 523 to move to the right, causing the latch 71 to rotate upward, and the latch 71 releases the hook 72. The first linear module 521 of the first clamping component 52 drives the first clamping plate 523 and the second clamping plate 532 to move the hanging plate and the latch 71 in the opposite direction to the hook 72, so that the door lock is opened. The first linear module 521 of the first clamping component 52 drives the first clamping plate 523 and the second clamping plate 532 to move the hanging plate and the latch 71 towards the hook 72, so that the latch 71 is locked on the hook 72. During the process of unlocking and locking the door lock, the first cylinder 61 of the camera assembly 6 drives the connecting bracket 62 to move the detection camera 63 downward to take pictures and detect the gap between the latch 71 and the hook 72 during the unlocking and locking process.

[0024] When the door lock is in the open state, the first linear module 521 of the first clamping assembly 52 drives the first clamping plate 523 and the second clamping plate 532 to move the latch 71 toward the hook 72. The second linear module 531 of the second clamping assembly 53 drives the second clamping plate 532 to move slowly to the left, causing the latch 71 to rotate slowly downward. When the contact of the latch 71 and the right contact of the electrical contact are connected, the camera assembly 6 takes a picture of the gap between the latch 71 and the hook 72. The second linear module 531 continues to drive the second clamping plate 532 to move to the left to release the latch 71. The latch 71 and the hook 72 are locked together. The camera assembly 6 takes another picture of the gap between the latch 71 and the hook 72. The change in the door lock gap is calculated by the algorithm.

[0025] In the above structure, the conveying mechanism 1, the testing fixture 3, and the counterweight assembly 4 work together to achieve the loading and positioning of the elevator sill 7. Furthermore, the drive assembly 5 and the camera assembly 6 work together to achieve automated detection of the door lock gap of the elevator sill 7, allowing for comprehensive detection of the door lock gap according to specific testing requirements. This elevator sill door lock gap detection equipment not only automates door lock detection but also improves detection efficiency and accuracy.

[0026] like Figure 3As shown, in one embodiment, the lifting assembly 51 of the elevator sill door lock gap detection device includes a first lifting cylinder 511 and a top plate 512. The driving end of the first lifting cylinder 511 is connected to the top plate 512. The first clamping assembly 52 includes a first linear module 521, a connecting plate 522, and a first clamping plate 523. The first linear module 521 is mounted on the top plate 512, and the driving end of the first linear module 521 is connected to the connecting plate 522. The first clamping plate 523 is vertically mounted on the connecting plate 522. The second clamping assembly 53 includes a second linear module 531 and a vertically arranged second clamping plate 532. The second linear module 531 is mounted on the connecting plate 522, and its drive end is connected to the second clamping plate 532. The second clamping plate 532 is located on one side of the first clamping plate 523. The first lifting cylinder 511 drives the first clamping plate 523 and the second clamping plate 532 to move upward, so that the second clamping plate 532 is located on the side of the pulley of the door lock latch 71, and the first clamping plate 523 is located on the side of another pulley. The first lifting cylinder 511 drives the top plate 512 to move the first clamping assembly 52 and the second clamping assembly 53 up and down, realizing the height adjustment of the first clamping plate 523 and the second clamping plate 532. The first linear module 521 of the first clamping assembly 52 drives the first clamping plate 523 and the second clamping assembly 53 to move horizontally, thereby driving the hanging plate on which the latch 71 is installed to move horizontally, simulating the door lock opening and closing operation of the elevator step 7. The second linear module 531 of the second clamping assembly 53 drives the second clamping plate 532 to rotate the latch 71, causing the latch 71 to rotate and either loosen or tighten the locking hook 72. This drive assembly 5 is configured to simulate the use state of the elevator step 7 door lock, and in conjunction with the camera assembly 6, achieves high-precision detection of the door lock gap.

[0027] like Figure 4 As shown, in one embodiment, the testing fixture 3 of the elevator sill door lock gap testing device includes a positioning plate 31. The positioning plate 31 is equipped with several positioning pins 32 for positioning the sill 7 and several electromagnets 33 for attracting the sill 7. The elevator sill 7 is manually placed on the positioning plate 31, and the positioning pins 32 extend into the positioning holes of the elevator sill 7 to position it. The electromagnets 33 on the positioning plate 31 attract the elevator sill 7, improving the positioning strength of the elevator sill 7 and preventing the elevator sill 7 from shaking during the testing process, which could affect the testing accuracy.

[0028] like Figure 2As shown, in one embodiment, the counterweight assembly 4 of the elevator sill door lock gap detection device includes two spring hooks 41, a detachable counterweight plate 42, and a second lifting cylinder 43 for lifting the counterweight plate 42. One end of the two spring hooks 41 is symmetrically mounted on the counterweight plate 42, and the other end of the two spring hooks 41 is engaged with the hanging plate of the sill 7. A support plate 44 is provided on the driving end of the second lifting cylinder 43, which is located below the counterweight plate 42. The support plate 44 for lifting the counterweight plate 42 is provided on the driving end of the second lifting cylinder 43. According to different balance requirements of the elevator sill 7, a corresponding counterweight plate 42 is selected, and then the two spring hooks 41 are symmetrically mounted on the counterweight plate 42 and hung in the hook through holes of the hanging plate. When the door lock of the elevator sill 7 is detected, the second lifting cylinder 43 drives the support plate 44 to move downward and disengage from the counterweight plate 42, so that the elevator sill 7 remains balanced. Once the inspection is complete, the second lifting cylinder 43 drives the support plate 44 to move upwards to support the counterweight plate 42, facilitating manual unloading of materials from the elevator sill 7. This counterweight assembly 4 improves the balance of the elevator sill 7's positioning.

[0029] like Figure 2 As shown, in one embodiment, the camera assembly 6 of the elevator sill door lock gap detection device includes a first cylinder 61, a connecting frame 62, and a detection camera 63. The drive end of the first cylinder 61 is connected to the connecting frame 62, and the connecting frame 62 is vertically slidably engaged with the detection frame 2. The detection camera 63 is mounted on one end of the connecting frame 62. The first cylinder 61 drives the connecting frame 62 to move the detection camera 63 up and down. When the elevator sill 7 is manually positioned, the first cylinder 61 drives the connecting frame 62 to move the detection camera 63 upward to the top of the detection frame 2, avoiding collisions when the manual loading of the elevator sill 7 occurs. After positioning, when the drive assembly 5 is activated, the first cylinder 61 drives the connecting frame 62 to move the detection camera 63 downward to take pictures and detect various states of the door lock gap. This configuration facilitates the photographic detection of the door lock gap.

[0030] like Figure 2 As shown, in one embodiment, the detection frame 2 of the elevator door lock gap detection device is equipped with a limiting component 64 for limiting the camera assembly 6. The limiting component 64 includes a limiting cylinder and a limiting rod. The driving end of the limiting cylinder is connected to the limiting rod, and the limiting cylinder drives the limiting rod to limit the camera assembly 6. When the first cylinder 61 drives the detection camera 63 to the top of the detection frame 2, the limiting cylinder of the limiting component 64 drives the limiting rod to limit the detection camera 63. This setting can prevent the detection camera 63 from falling and improve the safety of the equipment.

[0031] like Figure 1 As shown, in one embodiment, the conveying mechanism 1 of the elevator sill door lock gap detection device includes a conveying frame, a motor, a driving wheel, a driven wheel, and a belt winding around the driving wheel and the driven wheel. The driving wheel and the driven wheel are rotatably mounted at both ends of the conveying frame, and the motor is mounted at one end of the conveying frame. The drive end of the motor is connected to the driving wheel, and the motor drives the driving wheel to rotate the belt and the driven wheel. The elevator sill 7 is loaded onto the belt, and the motor drives the driving wheel to rotate the belt and the driven wheel to convey the elevator sill 7. This arrangement improves the conveying efficiency of the elevator sill 7.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
