DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-7 , the present invention provides an elevator braking detection device, including a detection component 100 and a braking component 200;

[0027] Among them, the detection component 100 includes a servo motor 101. The output end of the servo motor 101 is connected to a worm 102. The side surface of the worm 102 is connected to a worm gear 103. The surface of the worm gear 103 is fixedly connected to a guide disc 104. One end of the guide disc 104 is rotatably connected to two locking tongues 105. An articulated rod 106 is articulated between the two locking tongues 105. One end of one of the locking tongues 105 is connected to a centrifugal rod 107. A spring 108 is sleeved on the side surface of the centrifugal rod 107. The upper end of the centrifugal rod 107 is fixedly connected to a centrifugal weight 109. A steel cable 110 is wound around the side surface of the guide disc 104. Two supports 120 are installed on both sides of the guide disc 104. A steel ring 130 is embedded inside one side of the support 120. A plurality of locking blocks 140 are fixedly connected inside the steel ring 130;

[0028] The braking component 200 includes a suspension plate 201. The lower end of the suspension plate 201 is fixedly connected to two fixing blocks 202. Oblique notch grooves 203 are formed on the opposite surfaces of the two fixing blocks 202. Braking blocks 204 are installed inside the two oblique notch grooves 203. The upper ends of the two braking blocks 204 are fixedly connected to support rods 205. The ends of the two support rods 205 are connected to a lever 206. One end of the lever 206 is rotatably connected to a connecting rod 207. The end of the connecting rod 207 away from the lever 206 is fixedly connected to a fastening tube 208.

[0029] In a specific embodiment, the detection component 100 and the braking component 200 are configured to not only improve the detection effect of the braking component 200, thereby enhancing the practicality of the detection device, but also facilitate the disassembly of the detection device through the mutual cooperation of the above structures, thereby improving the disassembly convenience of each component. When performing the detection operation of the braking component 200, first start the servo motor 101 to drive the worm 102 to rotate, which can drive the worm gear 103 to rotate. When the elevator car falls with the braking component 200, the steel cable 110 rapidly descends along the fastening pipe 208, which can drive the guide disk 104 to rotate rapidly. Under the centrifugal force of the rotation of the guide disk 104, the centrifugal rod 107 and the centrifugal hammer 109 can rotate to contract the spring 108. Under the action of the centrifugal rod 107, two locking tongues 105 can be controlled to rotate and engage with two of the locking blocks 140. As the locking tongues 105 and the locking blocks 140 are engaged, the steel cable 110 pulls the fastening pipe 208 and the connecting rod 207 to descend. Cooperating with the lever 206 and the support rod 205, the two braking blocks 204 can be lifted and merged along the inclined slot 203, thereby clamping the steel wire rope between the two braking blocks 204. Therefore, it is convenient to detect the braking effect of the braking component 200, so as to enhance the practicality of the detection device.

[0030] Please refer to Figures 2-5 , one side of the guide disk 104 is fixedly connected with two rotating rods 111, and rotating holes 112 are formed on the surfaces of the two locking tongues 105. The rotating rods 111 are rotatably connected to the inside of the rotating holes 112.

[0031] In a specific embodiment, the rotating rod 111 is rotatably connected to the inside of the rotating hole 112, so as to facilitate the rotation of the locking tongue 105 around the rotating rod 111 and engage and fix with the locking block 140.

[0032] Please refer to Figures 2-5 , the lower end of the centrifugal rod 107 is fixedly connected with a plugging rod 121, and a plugging hole is formed at one end of one of the locking tongues 105. The plugging rod 121 is plugged into the inside of the plugging hole.

[0033] In a specific embodiment, the plugging rod 121 is plugged into the plugging hole 122 to facilitate the disassembly and assembly convenience of the centrifugal rod 107.

[0034] Please refer to Figures 2-5 , a fixing groove 131 is formed on one side of the support 120, and the steel ring 130 is fixedly installed inside the fixing groove 131.

[0035] In a specific embodiment, the fixing groove 131 is used to improve the installation stability of the steel ring 130, and further improve the stability of the braking detection.

[0036] Please refer to Figure 6 and Figure 7, at the ends of both struts 205, there are first sleeves 211 fixedly connected. The lever 206 is inserted into the interiors of the two first sleeves 211. One end of the connecting rod 207 is fixedly connected with a second sleeve 212, and the second sleeve 212 is sleeved on the side surface of the lever 206.

[0037] In a specific embodiment, the first sleeve 211, the second sleeve 212 and the connecting rod 207 are rotatably connected. When the angles of the strut 205 and the connecting rod 207 change, they can rotate along the lever 206 to lift the brake block 204.

[0038] Please refer to Figures 2-7 , the steel cable 110 is inserted into the interior of the fastening tube 208.

[0039] In a specific embodiment, the fastening tube 208 is used to enhance the connection strength between the steel cable 110.

[0040] Please refer to Figure 6 and Figure 7 , the brake block 204 is made of rubber.

[0041] In a specific embodiment, the rubber-made brake block 204 can increase the friction force with the steel wire rope and enhance the braking effect of the braking assembly 200.

[0042] Working principle: When performing the braking detection operation, first start the servo motor 101 to drive the worm 102 to rotate, which can drive the worm wheel 103 to rotate. When the elevator car falls with the braking assembly 200, the steel cable 110 can rapidly descend along the fastening tube 208, which can drive the guide disc 104 to rotate quickly. Under the centrifugal force of the rotation of the guide disc 104, the centrifugal rod 107 can cooperate with the centrifugal hammer 109 to rotate, causing the spring 108 to contract. Under the action of the centrifugal rod 107, it can control the rotation of the two lock tongues 105 to engage with two of the lock blocks 140. As the lock tongues 105 and the lock blocks 140 are engaged, the steel cable 110 pulls the fastening tube 208 and the connecting rod 207 to descend, and cooperate with the lever 206 and the strut 205 to lift the two brake blocks 204 and rise along the inclined slot 203 to merge, so as to clamp the steel wire rope between the two brake blocks 204, and further facilitate the detection of the braking effect of the braking assembly 200 to enhance the practicability of the detection device.
