Description

Technical Field

[0001] The present invention relates to the technical field of elevator compensation chains, and in particular to an anti-fracture compensation chain for an elevator and a use method thereof. Background Art

[0002] As a crucial component of the elevator system, the elevator compensating chain's design principles, material selection, tension variations, wear and lifespan predictions, safety performance and protective measures, maintenance and replacement cycles, and technological innovation and upgrade trends all directly impact the safety and stability of the elevator. Therefore, the safety performance of the compensating chain is a crucial consideration in elevator systems. During the design process, various protective measures are required, such as installing protective covers and strengthening the connections between chain links, to prevent safety accidents such as breakage or detachment of the compensating chain during operation. Existing anti-breakage compensating chains for elevators lack real-time detection of breakage, making them insecure and preventing further safety and breakage protection.

[0003] The existing anti-breakage compensation chain for elevators has the following defects:

[0004] 1. Patent document CN109941864B discloses a compensating chain and an elevator, "comprising a plurality of first links and a plurality of second links, wherein the first links are connected to the second links at intervals, the first links being provided with a cavity open at both ends, the first links being connected to a connecting rod which passes through the cavity, one end of the connecting rod being rotatably connected to a first connecting member, and the other end of the connecting rod being rotatably connected to a second connecting member, the first connecting member and the second connecting member both rotating along the circumference of the first link, the first link being located between the first and second connecting members, the connecting rod being sleeved with a double torsion spring, thereby preventing damage to the compensating chain due to excessive torsion, thereby improving the comfort and safety of elevator passengers." However, existing anti-fracture compensating chains for elevators cannot detect fractures in real time, making them unsafe.

[0005] 2. Patent document CN101445200A discloses an elevator car compensating chain, which "comprises a plurality of first links and a plurality of second links, the first links and the second links being interlocked with each other, the first and second links having holes with a longitudinal length greater than a transverse width, and at least one of the first and second links having a hole with a width greater at both ends than in the middle. In the present invention, the compensating chain has greater stability during elevator operation, thereby improving elevator comfort and safety." However, existing anti-breakage compensating chains for elevators cannot provide further protection in a broken state, and their anti-breakage properties are low.

[0006] 3. Patent document CN103183267B discloses an elevator compensating chain structure, which "comprises a metal core, an inner protective layer sheathed around the metal core, a plurality of cables evenly spaced on the outer circumference of the inner protective layer, and an outer protective layer sheathed around the plurality of cables. When the elevator compensating chain is connected between the counterweight and car sides of the elevator, the compensating chain electrically connects the electrical components on the counterweight and car sides via the cables within it. For example, when a position detection switch or safety clamp is installed on the counterweight side, the signal can be transmitted to the car side via the compensating chain and then to the elevator control system via a traveling cable to monitor the position or safety performance of the counterweight side, thereby improving the safety performance of the elevator. This eliminates the need for a traveling cable on the counterweight side, simplifies the layout, and reduces costs." However, existing anti-breakage compensating chains for elevators cannot be tightly connected to the elevator joint, reducing the stability of the connection.

[0007] 4. Patent document CN106144835A discloses a flexible guiding device for an elevator compensation chain or compensation cable, "including one or more flexible guide members, end fixing members, and auxiliary fixing members. The auxiliary fixing members are fixedly arranged in the hoistway, and the flexible guide members are connected to the auxiliary fixing members through the end fixing members; when there is one flexible guide member, the flexible guide member can guide the compensation chain or compensation cable in two dimensions; when there are multiple flexible guide members, each flexible guide member is connected end to end through the end fixing members and encloses an area; the area enclosed by the flexible guide members can guide the compensation chain or compensation cable in three dimensions. The present invention can effectively expand the protection and guiding range of the compensation chain or compensation cable guide device", but the impact force of the existing anti-breakage compensation chain for elevators during swinging cannot be buffered, which can easily damage the elevator compensation chain.

[0019] Preferably, the working steps of the elevator compensation chain are as follows:

[0020] S1. When the comparison result of the processing module shows that the chain is not broken, the processing module controls the alarm module not to start. At this time, the pressure sensor continuously detects the real-time connection status data of the detection chain and transmits it to the processing module for comparison with the normal connection status data of the detection chain until the comparison result of the processing module shows that the chain is broken. When the comparison result of the processing module shows that the chain is broken, the processing module controls the alarm module to start. After the alarm module is started, the monitoring computer in the alarm room starts to sound an alarm, thereby realizing the function of real-time detection of the broken state of the elevator compensation chain to improve safety;

[0021] S2, the function of the third plate is to provide support for the return spring. Pulling the pull rod drives the clamp head to move, which drives the return spring to move. The return spring moves the clamp head out of the slot, and the connecting head is then clamped into the slot. The friction block strengthens the connection friction of the connecting head. At this time, the pull rod is released and the return spring returns to the original position, driving the clamp head to clamp into the first slot to fix the connecting head. In this way, the steel rope is further protected in the event of a broken elevator compensation chain, improving safety and preventing breakage.

[0022] S3. The threaded rod is engaged with the threaded sleeve. After the frame is inserted into the elevator connection, the threaded rod is rotated to cooperate with the threaded sleeve to drive the pressure block to move. The movement of the pressure block drives the fixed head to move. The movement of the fixed head contacts the elevator connection and drives it to move. The movement of the fixed head drives the No. 6 spring to move. The movement of the No. 6 spring causes the fixed head to drive the pulley to move. The movement of the pulley causes the fixed head to move stably. The movement of the fixed head cooperates with the No. 6 spring to tightly connect with the elevator connection to make it stably fixed, thus realizing the function of tightly connecting the elevator compensation chain with the elevator connection and improving the connection stability.

[0023] S4. The function of the support box is to provide support for the No. 8 spring. When the chain swings, it drives the connecting piece to move, and the movement of the connecting piece drives the buffer block to move. The movement of the buffer block causes the connecting piece to drive the No. 8 spring to move. The movement of the No. 8 spring causes the connecting piece to cooperate with the buffer block and the No. 8 spring to buffer the impact force when the chain swings, thereby buffering the impact force when the elevator compensation chain swings and preventing the elevator compensation chain from being damaged.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention controls the alarm module to be inactive when the comparison result of the processing module indicates that the chain is not broken. At this time, the pressure sensor continuously detects the real-time connection status data of the detection chain and transmits it to the processing module for comparison with the normal connection status data of the detection chain until the comparison result of the processing module indicates that the chain is broken. When the comparison result of the processing module indicates that the chain is broken, the processing module controls the alarm module to be activated. After the alarm module is activated, the monitoring computer in the alarm room starts to sound an alarm, thereby realizing the function of detecting the breakage status of the elevator compensation chain in real time to improve safety.

[0026] 2. The present invention installs a third plate to provide support for the return spring. Pulling the pull rod drives the clamp head to move, which in turn drives the return spring to move. The return spring moves the clamp head out of the slot, at which point the connector is locked into the slot. The friction block strengthens the connection friction of the connector. At this time, releasing the pull rod allows the return spring to reset and drive the clamp head into the first slot to secure the connector. This ensures that in the event of a broken elevator compensating chain, the steel rope further protects it, improving safety and preventing breakage.

[0027] 3. The present invention is provided with a threaded rod that engages with a threaded sleeve. After the frame is clamped into the elevator connection, the threaded rod is rotated to cooperate with the threaded sleeve to drive the pressure block to move. The movement of the pressure block drives the fixed head to move. The movement of the fixed head contacts the elevator connection and drives it to move. The movement of the fixed head drives the No. 6 spring to move. The movement of the No. 6 spring causes the fixed head to drive the pulley to move. The movement of the pulley causes the fixed head to move stably. The movement of the fixed head cooperates with the No. 6 spring to tightly connect with the elevator connection to ensure stable fixation. This achieves the function of tightly connecting the elevator compensation chain and the elevator connection and improving the connection stability.

[0028] 4. The present invention is equipped with a support box to provide support for the No. 8 spring. When the chain swings, the connecting piece is driven to move, and the movement of the connecting piece drives the buffer block to move. The movement of the buffer block causes the connecting piece to drive the No. 8 spring to move. The movement of the No. 8 spring causes the connecting piece to cooperate with the buffer block and the No. 8 spring to buffer the impact force when the chain swings, thereby buffering the impact force when the elevator compensation chain swings and preventing the elevator compensation chain from being damaged.
