Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, specifically to an elevator sliding guide shoe anti-collision and shock absorption component. Background Technology

[0002] In modern buildings, elevators have become an indispensable vertical transportation tool. With the acceleration of urbanization and the continuous increase in building height, people have put forward higher requirements for the safety performance and operational comfort of elevators. However, the existing elevator sliding guide shoe technology has many shortcomings. In terms of safety protection, traditional elevator sliding guide shoes lack an effective emergency braking mechanism. When the elevator experiences emergency situations such as overspeeding, loss of control, or severe vibration, it cannot respond quickly and stop the elevator car. This makes the elevator extremely risky in emergency situations, which may lead to serious accidents such as car falling or collision, seriously threatening the lives of passengers. For example, in some older elevators, because the sliding guide shoes do not have a similar buffer mechanism, once the elevator control system malfunctions and causes overspeeding, only limited safety clamps and other devices can be relied upon. However, these devices may not be able to function in time under certain complex conditions, resulting in serious consequences.

[0003] In terms of shock absorption and durability, existing technologies are also unsatisfactory. The shock absorption measures of ordinary sliding guide shoes are limited, usually relying only on simple rubber pads or basic spring structures, which cannot fully absorb and dissipate the vibration energy generated during elevator operation. This results in significant vibration of the car during operation, which not only reduces passenger comfort but also causes elevator components to be frequently impacted, accelerating component wear and aging. Moreover, traditional shoe lining materials have poor wear resistance and are prone to wear and deformation during long-term friction with the guide rail, requiring frequent replacement, increasing maintenance costs and elevator downtime, and affecting the normal operating efficiency of the elevator. Therefore, there is an urgent need to improve the elevator sliding guide shoe anti-collision and shock absorption component to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This elevator sliding guide shoe anti-collision and shock absorption component, through the design of the buffer mechanism, when the elevator experiences emergencies such as overspeed, loss of control, or severe vibration, the iron balls inside the roller overcome the elastic force of the spring under the action of centrifugal force, contact the metal plate, and connect the circuit, thereby starting the motor. The motor drives the bidirectional screw to rotate, causing the locking block with anti-slip texture to quickly move towards the elevator guide rail and lock, realizing the locking of the shoe head against the guide rail, allowing the elevator car to stop moving in time, effectively avoiding possible serious accidents, and adding reliable protection for the life safety of passengers.

[0014] 2. The elevator sliding guide shoe anti-collision and shock absorption component, through the design of the buffer and shock absorption mechanism, consumes the energy of the vibration process when the elevator is running, suppressing the duration and amplitude of the vibration.

These designs greatly improve the smoothness of elevator operation, extend the service life of the equipment, bring passengers a more comfortable riding experience, and reduce equipment maintenance costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Based on existing technology, traditional elevator guide shoes lack an effective emergency braking mechanism. When the elevator experiences emergencies such as overspeeding, loss of control, or severe vibrations, they cannot respond quickly enough to stop the elevator car. This poses a significant safety risk in emergency situations, potentially leading to serious accidents such as car falls or collisions, severely threatening passenger lives. For example, in some older elevators, because the guide shoes lack a similar buffer mechanism as this component, if an elevator control system malfunction causes overspeeding, only limited safety brakes and other devices can be relied upon. These devices may not function promptly in certain complex situations, leading to serious consequences. Therefore, this device incorporates a buffer mechanism. Please refer to [link / reference]. Figures 1-3 This utility model provides a technical solution: an elevator sliding guide shoe anti-collision and shock absorption component, including a shoe seat 1, which is fixedly installed on the elevator car by bolts. The shoe seat 1 has a shoe toe 2 on its side. The upper and lower ends of the shoe toe 2 are fixedly installed with baffles 6 by screws 7. The side of the shoe toe 2 is integrally formed with a fixing block 4. A damper 5 is provided between the fixing block 4 and the shoe seat 1. The elevator sliding guide shoe anti-collision and shock absorption component includes a buffer mechanism and an anti-collision and shock absorption mechanism. The shoe toe 2 has a cavity 201. A fixing shaft 202 is fixedly installed in the cavity 201. A roller 203 is movably installed on the fixing shaft 202.

[0023] The roller 203 is provided with a limiting groove 204. A limiting rod 205 is fixedly installed in the limiting groove 204. An iron ball 206 is movably installed on the limiting rod 205. A spring 207 is fixedly installed between the iron ball 206 and the inner wall of the limiting groove 204. A metal piece 208 is fixedly installed at the front end of the limiting rod 205.

[0024] The limit rod 205 is an insulating rod, the roller 203 is an insulating roller, the roller 203 passes through the boot liner 3 and is in close contact with the elevator guide rail, the spring 207 and the metal plate 208 are respectively connected to the electrode switch, and the circuit is connected when the iron ball 206 contacts the metal plate 208.

[0025] A motor 209 is fixedly mounted on the side of the shoe head 2 via a mounting base. The output shaft of the motor 209 passes through the shoe head 2 and is fixedly mounted on the screw 210. A limit plate 211 is fixedly mounted on the end of the screw 210. The screw 210 is a bidirectional screw.

[0026] The shoe toe 2 is equipped with a recycling groove, and the recycling groove is equipped with a locking block 212. The locking block 212 is installed on both sides of the screw 210 by thread. The inner side of the locking block 212 is equipped with anti-slip texture. When the motor 209 is not started, the locking block 212 does not contact the side of the elevator guide rail.

[0027] Under normal operating conditions, the roller 203 is in close contact with the elevator guide rail, allowing it to rotate stably on the guide rail. The iron ball 206 is held in a specific position within the limit groove 204 by the spring 207. At this time, the motor 209 is not started, and the locking block 212 does not contact the side of the elevator guide rail. When the elevator experiences an emergency such as overspeeding, loss of control, or severe vibration, the roller 203's rotation speed increases sharply, generating a large centrifugal force. Under the action of centrifugal force, the iron ball 206 overcomes the elastic force of the spring 207 and moves along the limit rod 205 towards the metal plate 208. When bead 206 contacts metal sheet 208, the circuit is connected because spring 207 and metal sheet 208 are respectively connected to electrode switch. Motor 209 starts and the output shaft of motor 209 drives screw 210 to rotate. Screw 210 is a bidirectional screw. Its rotation causes locking blocks 212, which are installed on both sides by threads, to move quickly along screw 210 towards elevator guide rail. The inner side of locking block 212 is provided with anti-slip texture, which makes tight contact with elevator guide rail and locks it, so as to lock shoe head 2 against guide rail, so that elevator car stops moving in time and avoids serious accidents. Example

[0028] Based on Example 1, the shock absorption measures of ordinary sliding guide shoes are limited, typically relying on simple rubber pads or basic spring structures. This is insufficient to fully absorb and dissipate the vibration energy generated during elevator operation. This results in significant vibration of the car during operation, reducing passenger comfort and subjecting elevator components to frequent impacts, accelerating wear and aging. Furthermore, traditional shoe lining materials have poor wear resistance and are prone to wear and deformation during long-term friction with the guide rails, requiring frequent replacements. This increases maintenance costs and elevator downtime, affecting the elevator's normal operating efficiency. Therefore, this device incorporates an anti-collision and shock absorption mechanism. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: an elevator sliding guide shoe anti-collision and shock absorption component. The anti-collision and shock absorption mechanism includes a shoe base 1 and a shoe toe 2. The side of the shoe toe 2 is provided with a limiting groove 302. A guide rod 301 is movably installed in the limiting groove 302. A shoe liner 3 is fixedly installed at one end of the guide rod 301. The shoe liner 3 is located inside the shoe toe 2. The shoe liner 3 is made of a high-strength, high-wear-resistant metal-based composite material. The shoe liner 3 covers the elevator guide rail. The other end of the guide rod 301 is provided with a thread. The guide rod 301 passes through the shoe base 1. A spring 303 is provided on the guide rod 301. A nut 304 is movably installed on the guide rod 301 through the thread.

[0029] An inner cylinder 308 is fixedly installed at the upper end of the shoe base 1. An inner cylinder 309 is fixedly installed inside the inner cylinder 308. An outer cylinder 305 is movably installed outside the inner cylinder 308. A piston rod 306 is provided in the middle of the outer cylinder 305. The piston rod 306 is located inside the inner cylinder 309. A spring 307 is fixedly installed between the outer cylinder 305 and the inner cylinder 308. The outer cylinder 305 is fixedly installed at the bottom of the fixing block 4.

[0030] When the elevator vibrates during operation, the damper 5 consumes the energy during the vibration process, suppressing the duration and amplitude of the vibration. One end of the guide rod 301 is fixedly installed with the shoe liner 3, and the other end passes through the shoe seat 1 and is adjusted in position by the nut 304. When the elevator vibrates, the shoe liner 3 moves with the guide rod 301 in the limiting groove 302. By adjusting the position of the nut 304 on the guide rod 301, the tightness between the shoe liner 3 and the guide rail can be changed to adapt to different operating conditions. The inner cylinder 308, inner cylinder 309, outer cylinder 305, piston rod 306 and spring 307 at the upper end of the shoe seat 1 also participate in the vibration damping process. The outer cylinder 305 is fixedly installed at the bottom of the fixed block 4. When the elevator vibrates, the outer cylinder 305 moves relative to the inner cylinder 308, the piston rod 306 moves in the inner cylinder 309, and the spring 307 further buffers the vibration, improves the smoothness of the elevator operation, reduces component wear, and extends the service life of the equipment.
