Description

Technical Field

[0001] This invention relates to elevator testing equipment, specifically to a device for detecting the flatness of elevator doors and car doors. Background Technology

[0002] An elevator system includes: a car, a landing door sill, a car sill, and an elevator shaft. The elevator shaft has landing doors and windows for each floor. A landing door sill is located at the bottom of the landing door and window, and a car sill is located at the bottom of the car. The landing door sill and car sill are used to fill the gap between the car and the landing door and window to prevent feet from getting stuck in the gap.

[0003] Before installing the hall door sills and car sills, the bottom surface of the car has already been adjusted to be level with the bottom surfaces of the doors and windows on each landing. Therefore, during the installation of the hall door sills and car sills, it is necessary to adjust the top surfaces of the hall door sills and car sills to be level with the bottom surfaces of the doors and windows on each landing. Current technology involves manually measuring whether the top surfaces of the hall door sills and car sills are level with the bottom surfaces of the doors and windows, making the installation and adjustment of the hall door sills and car sills very cumbersome. Summary of the Invention

[0004] The present invention provides an elevator door and car door flatness position detection device to solve the problem of low installation efficiency of the hall door and car door steps due to the manual measurement of whether the top surface of the hall door step and the top surface of the car step are on the same plane as the inner bottom surface of the door and window.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides an elevator door and car door leveling position detection device, comprising: a base frame, a rotation adjustment mechanism, and a detection mechanism. The base frame can be installed on the bottom surface inside the car. The rotation adjustment mechanism is mounted on the base frame. The detection mechanism is rotatably connected to the rotation adjustment mechanism. The rotation adjustment mechanism can control whether the detection mechanism rotates relative to the base frame. The output end of the detection mechanism can detect whether the top surface of the landing door sill, the top surface of the car sill, and the bottom surface inside the landing door window are on the same horizontal plane.

[0006] Preferably, the base frame includes an air extraction cylinder and an air extraction adsorption mechanism, wherein the air extraction cylinder is adsorbed onto the bottom surface of the car interior by the air extraction adsorption mechanism.

[0007] Preferably, the suction-type adsorption mechanism includes a suction cup and a piston. The suction cup is installed at the bottom of the suction cylinder, and the suction cylinder has a cylindrical inner cavity that communicates with the suction cup. The suction cup is used to adsorb onto the bottom surface of the car. The piston is located inside the cylindrical inner cavity and can move up and down relative to the suction cylinder. An adjusting rod is installed on the piston and protrudes out of the suction cylinder.

[0008] Preferably, the base frame also includes a support frame, which is installed above the air extraction cylinder. The support frame is threadedly connected to the adjusting rod and does not obstruct the flow of gas at the top of the air extraction cylinder.

[0009] Preferably, the suction cup is installed at the bottom of the suction cylinder via a clamping screw, through which the suction cup passes, and the clamping screw is threadedly connected to the suction cylinder.

[0010] Preferably, a rotatable detection mechanism is installed on the support frame, and a rotation adjustment mechanism is located on the support frame. The movable part of the rotation adjustment mechanism is connected to the adjustment rod. The rotation adjustment mechanism allows the detection mechanism to rotate only when the piston and the adjustment rod rise to the point where the suction cup is firmly attached to the bottom surface of the car.

[0011] Preferably, the support frame includes: a lower pressure block and a support base, with limit arms connected to both ends of the lower pressure block, the support base fixed to the top of the air extraction cylinder, the lower pressure block connected to the top of the support base through the limit arms, and a detection mechanism and a rotation adjustment mechanism installed between the lower pressure block and the support base.

[0012] Preferably, the rotary adjustment mechanism includes: a guide rod, a first toothed ring, and a second toothed ring. The guide rod passes through the support frame, and the first toothed ring is fixed to the guide rod. The second toothed ring is installed next to the first toothed ring and is installed at the mounting end of the detection mechanism. The first toothed ring can mesh with the second toothed ring. The first toothed ring is installed to the adjustment rod, and the adjustment rod can rotate relative to the first toothed ring. The adjustment rod can drive the first toothed ring and the guide rod to rise and fall.

[0013] Preferably, the detection mechanism includes: a rotating ring, a detection arm, and detection heads. The rotating ring is the mounting end of the detection mechanism. The rotating ring is guided to rotate by the support frame. The second toothed ring is installed on the inner wall of the rotating ring. The detection arm is connected to the side of the rotating ring. The detection arm can rotate between two limiting arms. Three detection heads are installed on the top of the detection arm. The bottom of the three detection heads corresponds to the car step, the hall step, and the bottom surface of the landing door window, respectively.

[0014] Preferably, a separation space is formed inside the pressure block, into which the second toothed ring, after being separated from the first toothed ring, extends.

[0015] Compared to existing technologies, this invention offers the following advantages: The elevator door and car door leveling detection device's rotation adjustment mechanism, through the cooperation of a guide rod, a first toothed ring, and a second toothed ring, achieves precise control of the detection mechanism in both detection and non-detection states. In non-detection mode, the first and second toothed rings engage, effectively preventing the detection mechanism from rotating arbitrarily; at this time, the suction cup is released, allowing the base frame to be moved. During detection, the first and second toothed rings disengage, and the suction cup adheres to the bottom of the car, utilizing the detection mechanism for detection. This improves the flexibility and adaptability of the equipment, effectively enhancing the quality and efficiency of elevator installation and maintenance, and reducing safety hazards and maintenance costs caused by uneven elevator door and car door positions.

[0016] 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

[0021] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figures 1 to 3 As shown, this invention proposes an elevator door and car door leveling position detection device, comprising: a base frame 1, a rotation adjustment mechanism 2, and a detection mechanism 3. The base frame 1 can be installed on the bottom surface inside the car. The rotation adjustment mechanism 2 is mounted on the base frame 1. The detection mechanism 3 is rotatably connected to the rotation adjustment mechanism 2. The rotation adjustment mechanism 2 can control whether the detection mechanism 3 rotates relative to the base frame 1. The output end of the detection mechanism 3 can detect whether the top surface of the landing door sill, the top surface of the car sill, and the bottom surface inside the landing door / window are on the same horizontal plane. During operation, the base frame 1 is first installed on the bottom surface inside the car, serving to support and fix the overall device. The rotation adjustment mechanism 2 is installed on the base frame 1 and is rotatably connected to the detection mechanism 3. Through specific operation control, the detection mechanism 3 can be rotated or kept fixed relative to the base frame 1. When it is necessary to detect whether the top surface of the landing door sill, the top surface of the car sill, and the bottom surface inside the landing door / window are on the same horizontal plane, the rotation adjustment mechanism 2 controls the detection mechanism 3 to remain fixed, ensuring that the output end of the detection mechanism 3 can accurately align and detect the above three key positions.

[0022] The base frame 1 includes an air extraction cylinder 11 and an air extraction adsorption mechanism 12. The air extraction cylinder 11 is adsorbed onto the bottom surface of the car through the air extraction adsorption mechanism 12. The base frame 1 consists of an air extraction cylinder 11 and an air extraction adsorption mechanism 12. During operation, the air extraction cylinder 11 is adsorbed onto the bottom surface of the car through the air extraction adsorption mechanism 12. The air pressure difference generates an adsorption force, which makes the base frame 1 firmly fixed to the bottom surface of the car.

[0023] The suction-type adsorption mechanism 12 includes a suction cup 121 and a piston 122. The suction cup 121 is installed at the bottom of the suction cylinder 11. The suction cylinder 11 has a cylindrical inner cavity that communicates with the suction cup 121. The suction cup 121 is used to adsorb onto the bottom surface of the car. The piston 122 is located inside the cylindrical inner cavity and can move up and down relative to the suction cylinder 11. An adjusting rod 5 is installed on the piston 122 and protrudes out of the suction cylinder 11. Adjusting rod 5 includes: a first screw 51 and a second screw 52. The bottom end of the first screw 51 is connected to a piston 122, and the upper end of the first screw 51 is connected to the second screw 52. The outer diameter of the first screw 51 is larger than the outer diameter of the second screw 52. The second screw 52 is threadedly connected to the lower pressure block 131. A connecting hole is opened on the first toothed ring 22, through which the second screw 52 can pass. The outer diameter of the first screw 51 is larger than the connecting hole, and the outer diameter of the second screw 52 is smaller than the diameter of the connecting hole. A nut 53 is also threadedly connected to the second screw 52. The toothed ring 22 is clamped by the nut 53 and the end of the first screw 51. Initially, the piston 122 is in a low position, the air pressure in the suction cup 121 is high, and it is in a non-adsorption state. Rotating the adjusting rod 5 causes the piston 122 to move upward, the gas in the air extraction cylinder 11 is compressed and discharged from the suction cup 121. The suction cup 121 adsorbs the bottom surface of the car due to the pressure difference between the inside and outside. The base frame 1 is fixed. At this time, the rotating adjusting mechanism 2 is in an unlocked state. The rotating detection machine checks whether the top surface of the hall door sill, the top surface of the car sill, and the bottom surface of the landing door window are on the same horizontal plane.

[0024] The base frame 1 also includes a support frame 13, which is installed above the air extraction cylinder 11. The support frame 13 is threadedly connected to the adjusting rod 5, and does not obstruct the air flow at the top of the air extraction cylinder 11. The support frame 13 serves as the mounting base for the detection mechanism 3 and the rotation adjustment mechanism 2. Its threaded connection with the adjusting rod 5 allows for fine-tuning of the position after the equipment is fixed, ensuring that the detection mechanism 3 is accurately aligned with the target area. The support frame 13 has an inner cavity, and the piston 122 can extract air from the suction cup 121 within the inner cavity, allowing the suction cup 121 to adhere to the bottom surface of the car.

[0025] The suction cup 121 is installed at the bottom of the suction cylinder 11 via a clamping screw ring 4. The clamping screw ring 4 is for the suction cup 121 to pass through and is threadedly connected to the suction cylinder 11.

[0026] A rotatable detection mechanism 3 is mounted on the support frame 13. A rotation adjustment mechanism 2 is also located on the support frame 13. The movable part of the rotation adjustment mechanism 2 is connected to the adjustment rod 5. The rotation adjustment mechanism 2 allows the detection mechanism 3 to rotate only when the piston 122 and the adjustment rod 5 rise to the point where the suction cup 121 is firmly adhered to the bottom surface inside the car. The threaded clamping ring 4 can be rotated to install and remove the suction cup 121 without the need for additional tools.

[0027] The support frame 13 includes a lower pressure block 131 and a support base 132. Limiting arms 133 are connected to both ends of the lower pressure block 131. The support base 132 is fixed to the top of the suction cylinder 11. The lower pressure block 131 is connected to the top of the support base 132 via the limiting arms 133. A detection mechanism 3 and a rotation adjustment mechanism 2 are installed between the lower pressure block 131 and the support base 132. When the lower pressure block 131 and the support base 132 are engaged, they can stably support the detection mechanism 3 and the rotation adjustment mechanism 2, ensuring their stability during the detection process and preventing the detection mechanism 3 from shifting due to vibration or external force. The fixed connection between the support base 132 and the suction cylinder 11 further enhances the stability of the entire base frame 1, enabling the equipment to withstand certain external forces after adsorption and fixation without affecting the detection work.

[0028] The rotating adjustment mechanism 2 includes a guide rod 21, a first toothed ring 22, and a second toothed ring 23. The guide rod 21 passes through the support frame 13, and the first toothed ring 22 is fixed to the guide rod 21. The second toothed ring 23 is installed next to the first toothed ring 22 and is mounted on the mounting end of the detection mechanism 3. The first toothed ring 22 can mesh with the second toothed ring 23. The first toothed ring 22 is mounted to the adjusting rod 5, which can rotate relative to the first toothed ring 22. The adjusting rod 5 can drive the first toothed ring 22 and the guide rod 21 to rise and fall. When the adjusting rod 5 drives the first toothed ring 22 and the guide rod 21 to rise, the first toothed ring 22 disengages from the second toothed ring 23. At this time, the suction cup 121 adheres to the bottom of the car, and the angle of the detection mechanism 3 is adjusted to detect whether the three sides are level. After the detection is completed, the rotating adjusting rod 5 moves downward, and the first toothed ring 22 meshes with the second toothed ring 23. At this time, the detection mechanism 3 cannot rotate to avoid damage caused by random rotation. At this time, the suction cup 121 can be lifted off the ground for easy movement.

[0029] The detection mechanism 3 includes a rotating ring 31, a detection arm 32, and a detection head 33. The rotating ring 31 is the mounting end of the detection mechanism 3. The rotating ring 31 is guided to rotate by the support frame 13. The second toothed ring 23 is installed on the inner wall of the rotating ring 31. The detection arm 32 is connected to the side of the rotating ring 31. The detection arm 32 can rotate between the two limiting arms 133. The top of the detection arm 32 is equipped with three detection heads 33. The bottom of the three detection heads 33 corresponds to the car step, the hall step, and the bottom surface of the landing door window, respectively. The rotating ring 31 serves as the mounting end and is guided to rotate by the support frame 13. The engagement or disengagement of the second toothed ring 23 installed on its inner wall with the first toothed ring 22 realizes the switching between fixing and rotating of the detection mechanism 3. The rotating ring 31 is connected to the detection arm 32 on its side. The detection arm 32 rotates between the two limiting arms 133, which limits the rotation range of the detection arm 32 and prevents excessive rotation from causing equipment damage or detection errors. The top of the detection arm 32 is equipped with three detection heads 33, which correspond to the inner bottom surface of the car step, the hall step, and the landing door window, respectively, and can simultaneously detect whether the three are coplanar.

[0030] A disengagement space is formed within the lower pressure block 131, into which the second toothed ring 23, after disengaging from the first toothed ring 22, extends. When the base frame 1 needs to be moved, the rotating threaded rod moves upward. At this time, the first toothed ring 22 disengages from the second toothed ring 23, the first toothed ring 22 is located in the disengagement space, and the rotating ring 31 can rotate between the limiting arms 133.

[0031] 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.
