Description

Technical Field

[0001] This utility model relates to the field of elevator traction equipment technology, specifically to a traction mechanism for a box elevator. Background Technology

[0002] An elevator traction system is a type of elevator drive device, mainly consisting of a transmission device, motor, brake, and suspension components. It employs a dedicated intelligent control system for elevators, featuring a stable and reliable drive method, a high-performance door drive structure, and a high-strength car design. The traction method is a key factor determining the elevator's operating speed and comfort.

[0003] In related technologies, the traction mechanism of the box elevator, a commonly used vertical transportation equipment in high-rise buildings, is the core power component. It mainly drives the traction sheave to rotate through the traction machine and uses the friction between the traction sheave and the traction rope to drive the car to rise and fall.

[0004] Most existing traction mechanisms lack an early warning structure for traction rope breakage. When the internal steel wires of the traction rope break due to long-term wear, an early warning signal cannot be issued in time. The condition of the traction rope can only be judged by regular manual inspection. If the inspection is neglected, or the traction rope is damaged faster due to sudden factors (such as impact or corrosion), the traction rope breakage can only be detected by moving the vehicle, which can easily leave unnecessary safety hazards. To solve the above problems, a traction mechanism for a box elevator is proposed. Utility Model Content

[0005] In view of this, the present invention provides a traction mechanism for a box elevator. The present invention generates infrared light through an infrared light emitting tube, which directs the light toward the traction rope. When the infrared light is blocked by the traction rope, it is determined that the rope is not broken. When the infrared light is not blocked by the traction rope, it shines onto the infrared light receiving tube, which is then determined to be a broken rope. The status is converted into a digital signal that can be recognized by the data box, thereby enabling real-time monitoring of the traction rope's status. When the traction rope's status is abnormal, it can be detected and repaired immediately, thereby reducing the probability of safety accidents caused by traction rope breakage.

[0006] To solve the above-mentioned technical problems, this utility model provides a traction mechanism for a box elevator, including a motor mounted on the top of the frame, a car mounted on the bottom of the frame, a pulley block mounted on the top of the car, slide rails mounted on both sides of the car, a counterweight structure mounted on one side of the car, a traction rope mounted on the bottom of the motor, the traction rope being connected to the pulley block for traction, a support plate mounted on the top of the frame, an opening on the support plate for the movement of the traction rope, a detection ring mounted on the opening, a positioning component mounted on the left and right sides of the detection ring, the detection ring being located on the surface of the traction rope, a cavity being provided inside the detection ring, a detection device being installed inside the cavity, and an anti-vibration component being provided at the bottom of the support plate.

[0007] The detection ring is circular, and a first groove is provided on one side of the inner side of the detection ring. The first groove is used to install an infrared light emitting tube, and a second groove is provided on the opposite side of the first groove. The second groove is used to install an infrared light receiving tube.

[0008] The detection device includes an infrared light emitting tube disposed in a first groove for emitting infrared light and an infrared light receiving tube disposed in a second groove for receiving infrared light. The light-emitting end of the infrared light emitting tube corresponds to the inlet end of the infrared light receiving tube, and the light-emitting axis of the infrared light emitting tube illuminates the traction rope.

[0009] Each positioning component includes an arc-shaped clamping block connected to the outer wall of the detection ring. The arc-shaped clamping block is used to fix the detection ring. A support rod is provided on the side of the arc-shaped clamping block away from the detection ring. The support rod is used to connect the detection ring to the support plate. The support rod is L-shaped. A tripod is provided at the bottom of each support rod. The tripod is used to reinforce the connection between the support rod and the support plate.

[0010] A support sleeve is connected to the other side of the detection ring. The support sleeve is used to insert cables and install the signal processing module. The support sleeve is also used to reinforce and fix the connection between the detection ring and the support plate. The signal processing module is installed inside the support sleeve. The signal processing module is used to connect the infrared light emitting tube and the infrared light receiving tube. Both the infrared light emitting tube and the infrared light receiving tube are electrically connected to the signal processing module through cables. On the side of the signal processing module away from the detection ring, a data box is connected through a cable. The data box is used to detect the infrared light blocking status. When the infrared light receiving tube receives infrared light, it is determined that the traction rope is broken. When the infrared light receiving tube does not receive infrared light, it is determined that the traction rope is not broken. The data box is also equipped with a false judgment unit.

[0011] The top of the data box is equipped with an audible and visual alarm, which is used to alert personnel to any abnormalities in the traction rope.

[0012] The anti-shake component includes a limiting sleeve located on the surface of the traction rope. The limiting sleeve is used to prevent the traction rope from swinging too much. The limiting sleeve is cylindrical, and a pair of positioning rods are provided on the surface of the limiting sleeve. The positioning rods are used to connect the limiting sleeve to the bottom of the support plate. The positioning rods are L-shaped, and each positioning rod is connected to the bottom of the support plate.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Infrared light is generated by an infrared light emitting tube and directed towards the traction rope. When the infrared light is blocked by the traction rope, it is determined that the rope is not broken.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-8 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] like Figure 1-8 As shown: This embodiment provides a traction mechanism for a box elevator, including a motor 101 mounted on top of a frame 100. The frame 100 consists of upper and lower base plates and columns, supporting the entire device. A car 102 is mounted at the bottom of the frame 100. A pulley system 103 is mounted on top of the car 102, comprising multiple pulleys. By changing the transmission direction of the wire rope, force transmission and motion conversion are achieved. Slide rails 104 are mounted on both sides of the car 102, guiding the movement of the car 102 and ensuring its stable, linear operation. A counterweight structure 105 is provided on the side, a traction rope 106 is provided at the bottom of the motor 101, the traction rope 106 is connected to the pulley block 103 for traction, a support plate 107 is provided on the top of the frame 100, an opening 108 is provided on the support plate 107 for the movement of the traction rope 106, a detection ring 200 is provided on the opening 108, a positioning component 300 is provided on the left and right sides of the detection ring 200, the detection ring 200 is located on the surface of the traction rope 106, a cavity is provided inside the detection ring 200, a detection device 400 is provided inside the cavity, and an anti-shake component 500 is provided at the bottom of the support plate 107.

[0020] In use, infrared light is generated by infrared light emitting tube 401 and directed towards the traction rope 106. When the infrared light is blocked by the traction rope 106, it is determined that the rope is not broken. When the infrared light is not blocked by the traction rope 106 and shines on the infrared light receiving tube 402, it is determined that the rope is broken and the status is converted into a digital signal that can be recognized by the data box 206. This allows for real-time monitoring of the status of the traction rope 106. When the traction rope 106 is in an abnormal state, it can be detected and repaired immediately, thereby reducing the probability of safety accidents caused by the breakage of the traction rope 106.

[0021] This embodiment provides a traction mechanism for a box elevator. like Figure 1 , 2As shown in Figures 3 and 4: The detection ring 200 is circular. A first groove 202 is provided on one side of the detection ring 200. The first groove 202 is rectangular and is embedded in the detection ring 200. The first groove 202 and the second groove 203 are symmetrically designed. The first groove 202 is used to install the infrared light emitting tube 401. A second groove 203 is provided on the opposite side of the first groove 202. The second groove 203 is embedded in the detection ring 200 and is used to install the infrared light receiving tube 402.

[0022] like Figure 1 , 2 As shown in Figures 3 and 4: The detection device 400 includes an infrared light emitting tube 401 disposed in the first groove 202. The infrared light emitting tube 401 and the first groove can be fixedly connected by glue. The infrared light emitting tube 401 is used to emit infrared light, which will directly hit the surface of the traction rope 106. The wavelength selection needs to match the reflective characteristics of the traction rope 106 material, such as steel cable, to ensure that the light can effectively cover the detection area. The infrared light emitting tube 401 includes an infrared light-emitting chip for generating infrared light. A microlens is disposed on the surface of the chip. The top shell of the infrared light emitting tube 401 is made of heat dissipation material. The infrared light emitting tube 401 is provided with positive and negative interfaces. An infrared light receiving tube 402 is disposed in the second groove 203. The two grooves 203 and the infrared light receiver tube 402 can be fixedly connected by glue. When the traction rope 106 is intact, the infrared light received by the infrared light receiver tube 402 is weak. When the traction rope 106 is broken, the infrared light received by the infrared light receiver tube 402 is strong. The infrared light receiver tube 402 is used to receive the infrared light reflected back from the surface of the traction rope 106. When the traction rope 106 is worn, cracked or broken, the surface roughness and reflectivity will change, and the intensity of the light signal captured by the receiver in the infrared light receiver tube 402 will also change accordingly. The light-emitting end of the infrared light emitting tube 401 corresponds to the input end of the infrared light receiver tube 402, and the light-emitting axis of the infrared light emitting tube 401 illuminates the traction rope 106.

[0023] The effect is as follows: the infrared light emitting tube 401 is used to emit infrared light, and the infrared light receiving tube 402 is used to receive the infrared light reflected back from the surface of the traction rope 106. When the traction rope 106 is worn, cracked or broken, the surface roughness and reflectivity will change, and the intensity of the light signal captured by the receiver in the infrared light receiving tube 402 will also change accordingly.

[0024] like Figure 1 , 2As shown: Each positioning component 300 includes an arc-shaped clamping block 301 connected to the outer wall of the detection ring 200. The arc-shaped clamping block 301 is welded to the outer arc wall of the detection ring 200 and is used to fix the detection ring 200. A support rod 302 is provided on the side of the arc-shaped clamping block 301 away from the detection ring 200. The support rod 302 is welded to the arc-shaped clamping block 301 and is used to connect the detection ring 200 to the support plate 107. The support rod 302 is L-shaped. A tripod 303 is provided at the bottom of each support rod 302. One side of the tripod 303 is welded to the support rod 302, and the other side of the tripod 303 is fixed to the support plate 107 by bolts. The tripod 303 is used to reinforce the connection between the support rod 302 and the support plate 107.

[0025] Its effects are as follows: the arc-shaped clamp 301 is used to fix the detection ring 200, the support rod 302 is used to connect the detection ring 200 to the support plate 107, and the tripod 303 is used to reinforce the connection between the support rod 302 and the support plate 107.

[0026] like Figure 1 , 2As shown in Figures 3, 4, 5, and 6: A support sleeve 204 is connected to the other side of the detection ring 200. The support sleeve 204 is rectangular and made of stainless steel. The support sleeve 204 is welded to the detection ring 200, and its bottom is welded to the support plate 107. The support sleeve 204 is used to pass through the cable 201 and to install the signal processing module 205. The support sleeve 204 also reinforces the connection between the detection ring 200 and the support plate 107. The signal processing module 205 is installed inside the support sleeve 204. The signal processing module 205 can receive the light signal from the infrared light receiver tube 402, convert it into an electrical signal, pass it through the built-in photoelectric converter, and then be compared by the microprocessor with the preset "normal" signal. If the signal exceeds the "reflection threshold," it is determined that the traction rope 106 is abnormal. The signal processing module 205 is used to connect the infrared light emitting tube 401 and the infrared light receiving tube 402. Both the infrared light emitting tube 401 and the infrared light receiving tube 402 are electrically connected to the signal processing module 205 via cable 201. The side of the signal processing module 205 away from the detection ring 200 is connected to the data box 206 via a cable. The data box 206 includes components such as a power module, a signal processing chip, a signal interface module, and a communication module. The outer shell of the data box 206 has a dustproof structure, and the data box 206 has an anti-interference shielding layer. This signal processing chip can be a 74HC logic chip. The STM32F0 series or low-cost microcontrollers are used to determine the signal status of the infrared light receiver 402 and convert it into a digital signal that the data box 206 can recognize. The data box 206 is used to detect the blocking status of infrared light. When the infrared light receiver 402 receives infrared light, it is determined that the traction rope 106 is broken. When the infrared light receiver 402 does not receive infrared light, it is determined that the traction rope 106 is not broken. The data box 206 is also equipped with a false alarm unit. The top of the data box 206 is equipped with an audible and visual alarm 207, which is used to remind personnel that the traction rope 106 is abnormal.

[0027] Its effect is as follows: the support sleeve 204 is used to insert the cable 201 and install the signal processing module 205. The signal processing module 205 can receive the light signal from the infrared light receiving tube 402 and convert it into an electrical signal. After passing through the built-in photoelectric converter, the signal is compared by the microprocessor with the preset "normal reflection threshold". If the signal exceeds the threshold, it is determined that there is an abnormality in the traction rope 106. The top of the data box 206 is equipped with an audible and visual alarm 207, which is used to remind personnel that there is an abnormality in the traction rope 106.

[0028] like Figure 6 , 7As shown in Figure 8: The anti-shake component 500 includes a limiting sleeve 501 located on the surface of the traction rope 106. The inner wall of the limiting sleeve 501 is provided with a rubber sleeve. The limiting sleeve 501 is used to prevent the traction rope 106 from swinging too much. The limiting sleeve 501 is cylindrical. A pair of positioning rods 502 are provided on the surface of the limiting sleeve 501. The positioning rods 502 are welded to the outer wall of the limiting sleeve 501. The other end of the positioning rods 502 is welded to the support plate 107. The positioning rods 502 are used to connect the limiting sleeve 501 to the bottom of the support plate 107. The positioning rods 502 are L-shaped. Each positioning rod 502 is connected to the bottom of the support plate 107.

[0029] Working principle: Infrared light is generated by infrared light emitting tube 401 and shines on the traction rope 106. When the infrared light is blocked by the traction rope 106, it is determined that the rope is not broken. When the infrared light is not blocked by the traction rope 106 and shines on the infrared light receiving tube 402, it is determined that the rope is broken. The status is converted into a digital signal that can be recognized by data box 206. The signal processing module 205 receives the light signal from the infrared light receiving tube 402 and converts the light signal into an electrical signal through the photoelectric connector. The microprocessor then compares the signal with the preset "normal reflection threshold". If the signal exceeds the threshold, it is determined that there is an abnormality in the traction rope 106. The communication module in data box 206 then transmits the information to the central control platform. At the same time, the audible and visual alarm 207 sounds an alarm. This allows for real-time monitoring of the status of the traction rope 106. When the traction rope 106 is abnormal, it can be detected and repaired immediately, thereby reducing the probability of safety accidents caused by the breakage of the traction rope 106.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
