At present, judging from the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles and electric cars, as well as in many fields such as military equipment and aerospace. . As the application fields of power batteries continue to expand, their market demand is also constantly expanding.

As the demand for batteries increases, higher requirements are put forward for battery production efficiency. For example, in the battery transportation link, if there is a higher transportation efficiency, it will help improve battery production efficiency. Battery transport involves transporting batteries via elevators to transport batteries to different height locations. In the process of transporting batteries through the elevator, not only the transportation efficiency needs to be considered, but also the safety performance of the elevator should be considered. The safety performance of elevators in related technologies is low, and safety accidents such as equipment damage and casualties are prone to occur during the transportation of batteries. Especially for some elevators that use chain-type drive mechanisms, the breakage of the transmission chain is one of the causes of safety problems. Moreover, the structural strength of each part of the transmission chain along its length is the same. It is not certain whether the elevator will be damaged during operation. Wherever the transmission chain breaks, the elevator in this case has greater safety risks and also makes it difficult to take safety protection measures.

Based on the above considerations, in order to alleviate the problem of poor safety performance of the elevator, embodiments of the present application provide an elevator. The elevator includes a frame, a bearing member and a driving mechanism. The driving mechanism includes a driving member, a sprocket, a transmission chain and accessories. The heavy parts, load-bearing parts and counterweight parts are respectively connected to both ends of the transmission chain. The transmission chain bypasses the sprocket and meshes with the sprocket. The sprocket is connected to the output end of the driving part. The driving part is used to drive the sprocket to rotate. The sprocket drives the load-bearing part to rise and fall relative to the frame; the load-bearing part and/or the counterweight part are connected to the transmission chain through a connecting piece, and the strength of the connecting piece is smaller than the strength of the transmission chain.

The strength of the connecting piece is less than that of the transmission chain. Among the transmission chain and the connecting piece, the connecting piece is the first to break. This way, the location of the accident can be accurately known and targeted safety protection measures can be taken.

In addition, the chain-type drive mechanism drives the load-bearing parts to lift and lower. The transmission chain has good pressure resistance, wear resistance, and high temperature resistance, which is beneficial to improving the stability and safety of the lifting of the load-bearing parts of the elevator.

The two ends of the transmission chain are connected to the load-bearing part and the counterweight part respectively. When the driving part drives the load-bearing part to rise, the counterweight part descends to provide auxiliary force for the driving part to drive the sprocket to rotate, which is beneficial to reducing power consumption and saving costs.

The hoist provided by the embodiment of the present application can be used in, but is not limited to, battery production, battery transportation and other fields.

The frame 10 is the skeleton structure of the hoist 100 . The rack 10 can be in various structural forms, which is not limited in this application. For example, the rack 10 can be a rectangular frame structure.

The frame 10 may be provided with guide rails that cooperate with the bearing member 20, and the guide rails extend in the up and down direction. The driving mechanism 30 drives the bearing member 20 to rise and fall along the extension direction of the guide rail, which can ensure that the bearing member 20 rises and falls in the up and down direction, thereby improving the stability of the bearing member 20 in lifting.

The carrier 20 is used to carry the object to be transported. The carrier 20 can be raised and lowered to transport the object placed on the carrier 20 to different height positions. The carrier 20 may be a car. Depending on the field of application of the elevator 100, the target parts can also be Differently, for example, if the elevator 100 is used in the field of battery production and transportation, the target part may be a battery or various component structures of the battery.

The driving member 31 may be a motor, a motor, or the like. The driving member 31 is installed on the frame 10 . In the middle of this embodiment, the driving member 31 is installed on the upper end of the frame 10 .

As shown in Figure 5, the sprocket 32 is a wheel with cog-type sprocket teeth. The driving member 31 can drive the sprocket 32 to rotate forward or reversely. The direction of the rotation axis of the sprocket 32 may be vertical up and down. The transmission chain 33 is wound around the sprocket 32 and the sprocket 32 is meshed with the transmission chain 33. A part of the transmission chain 33 is located on one side of the sprocket 32 along its radial direction, and a part of the transmission chain 33 is located on one side of the sprocket 32 along its radial direction. The other side.

The counterweight 34 is a structure connected to one end of the transmission chain 33 and has a relatively large weight.

When the driving member 31 drives the sprocket 32 to rotate forward, the bearing member 20 rises and the counterweight 34 descends; when the driving member 31 drives the sprocket 32 to reverse, the bearing member 20 descends and the counterweight 34 rises.

It may be that only the counterweight 34 is connected to one end of the transmission chain 33 through the connecting member 40 , and the other end of the transmission chain 33 is directly connected to the bearing member 20 . It is also possible that only the bearing member 20 is connected to one end of the transmission chain 33 through the connecting member 40 , and the other end of the transmission chain 33 is directly connected to the counterweight 34 . It is also possible that the counterweight 34 is connected to one end of the transmission chain 33 through the connecting member 40 , and the bearing member 20 is connected to the other end of the transmission chain 33 through the connecting member 40 . In this embodiment, please continue to refer to FIG. 5 , the bearing member 20 is connected to the transmission chain 33 through the connecting member 40 , and the other end of the transmission chain 33 is directly connected to the counterweight 34 .

Strength refers to the ability of a material to resist damage under the action of external forces. The better the strength, the greater the external force the material can withstand; the weaker the strength, the smaller the external force the material can withstand. If the strength of the connecting piece 40 is smaller than the strength of the transmission chain 33 , the force that causes the connecting piece 40 to break is smaller than the force that causes the transmission chain 33 to break.

Therefore, among the transmission chain 33 and the connecting piece 40, the connecting piece 40 is the first one to break, so that the location of the accident can be accurately known, so that targeted safety protection measures can be taken. In this application, the chain-type driving mechanism 30 is used to drive the load-bearing part 20 to lift. The transmission chain 33 has good pressure resistance, wear resistance, and high temperature resistance, which is beneficial to improving the lifting performance of the load-bearing part 20 of the hoist 100. Stability and safety performance. Both ends of the transmission chain 33 are respectively connected to the load-bearing member 20 and the counterweight 34. When the driving member 31 drives the load-carrying member 20 to rise, the counterweight 34 descends to provide auxiliary force for the driving member 31 to drive the sprocket 32 to rotate, which is beneficial to Reduce power consumption and save costs.

As shown in FIG. 6 , in some embodiments, the connecting member 40 is a safety pin, and the material hardness of the connecting member 40 is smaller than the hardness of the transmission chain 33 .

The safety pin can be a rod-shaped structure. In an embodiment in which the bearing member 20 is connected to one end of the transmission chain 33 through the connecting member 40 and the other end of the transmission chain 33 is directly connected to the counterweight 34, one end of the safety pin is connected to the bearing member 20 and the safety pin protrudes from the bearing member. 20, the part of the safety pin protruding from the bearing member 20 is connected to the transmission chain 33. The portion of the safety pin protruding from the surface of the carrier 20 may be provided with a mounting hole 41 , and the links of the transmission chain 33 may be inserted into the mounting hole 41 to connect the transmission chain 33 to the connector 40 , such as at the A link at one end is inserted into the mounting hole 41 . Of course, the transmission chain 33 can also be connected to the connector 40 in other ways, such as welding.

Hardness refers to the ability of a material to locally resist hard objects from being pressed into its surface. It is also one of the indicators of the material's wear resistance. The harder the material is, the harder it is for hard objects to press into its surface, and the material's wear resistance is stronger; the harder the material is, the easier it is for hard objects to press into its surface, and the material's wear resistance is weaker.

The hardness of the material of the connecting piece 40 is less than that of the transmission chain 33, so the wear resistance of the connecting piece 40 is weaker than that of the transmission chain 33. Therefore, among the transmission chain 33 and the connecting piece 40, the connection is the first to wear and break. Part 40, so that the location of the accident can be accurately known, so that targeted safety protection measures can be taken.

In some embodiments, a wear-resistant layer is provided at the surface where the drive chain 33 contacts the connector 40 .

The wear resistance of the material of the wear-resistant layer may be better than that of the transmission chain 33 . The material of the wear-resistant layer can be nano-ceramic materials, tungsten carbide alloy materials, polymer ceramic polymer materials, etc. The wear-resistant layer can be provided on the contact surface of the transmission chain 33 and the connector 40 by spraying, bonding through an adhesive layer, or other methods.

The provision of the wear-resistant layer can enhance the wear-resistant performance of the contact position between the transmission chain 33 and the connecting piece 40, so that the transmission chain 33 is not easily broken due to wear, thereby improving the safety performance of the elevator 100.

In some embodiments, an anti-rust layer is provided on the surface of the transmission chain 33 and no anti-rust layer is provided on at least part of the surface of the connecting member 40; or, there is an anti-rust layer on both the surface of the transmission chain 33 and the surface of the connecting member 40. Anti-rust layer, wherein the thickness of the anti-rust layer on at least part of the surface of the connecting piece 40 is smaller than the thickness of the anti-rust layer on the surface of the transmission chain 33 .

The anti-rust layer can slow down or prevent the surface oxidation of the material to improve the corrosion resistance of the material. The material of the anti-rust layer can be anti-rust oil, peelable plastic, etc. The anti-rust layer can be provided on the surface of the material by coating, electroplating and other methods.

Providing an anti-rust layer on the surface of the transmission chain 33 can improve the corrosion resistance of the transmission chain 33 and thereby increase the service life of the transmission chain 33 . At least a part of the surface of the connector 40 is not provided with an anti-rust layer. It can be understood that only a part of the surface of the connector 40 may not be provided with an anti-rust layer, and the other part may be provided with an anti-rust layer. In this case, the anti-corrosion performance of the connector 40 will be weaker than As for the transmission chain 33, the connector 40 is the first to suffer from corrosion and fracture, so that the location of the accident can be accurately known and targeted safety protection measures can be taken.

In an embodiment where both the surface of the transmission chain 33 and the surface of the connector 40 are provided with an anti-rust layer, the thickness of the anti-rust layer on at least part of the surface of the connector 40 is smaller than the thickness of the anti-rust layer on the surface of the transmission chain 33, It can be understood that if the thickness of all the anti-rust layers of the connecting piece 40 is less than the thickness of the anti-rust layer of the transmission connection, or the thickness of a part of the anti-rust layer of the connecting piece 40 is less than the thickness of the anti-rust layer of the transmission chain 33, then the thickness of the connecting piece The anti-corrosion performance of 40 is weaker than that of the transmission chain 33, so the connector 40 is the first to suffer from corrosion and fracture. In this way, the location of the accident can be accurately known, and safety protection measures can be taken in a targeted manner.

As shown in Figure 7, in some embodiments, the hoist 100 further includes a safety rope 50. Both ends of the safety rope 50 are connected to the load-bearing member 20 and the counterweight 34 respectively. The safety rope 50 is configured to break at the connection member 40. The weight of the counterweight 34 and the load bearing 20 is then carried.

When the connecting member 40 is not broken, the transmission chain 33 bears the gravity of the load-bearing member 20 and the counterweight 34 and can suspend the load-bearing member 20 and the counterweight 34. The safety rope 50 can be free from the load-bearing member 20 and the counterweight. 34 pull force. The length of the safety rope 50 may be greater than the length of the drive chain 33 . If the connecting member 40 is broken, the transmission chain 33 can no longer carry the counterweight 34 and the load-bearing member 20, but carries the gravity of the counterweight 34 and the load-bearing member 20 through the safety cable 50. The safety cable 50 can suspend the counterweight. 34 and bearing member 20.

The safety rope 50 can carry the counterweight 34 and the load-bearing member 20 after the transmission chain 33 breaks, thereby reducing the risk of the counterweight 34 and the load-bearing member 20 falling rapidly under the action of gravity due to the breakage of the transmission chain 33, thereby causing a safety accident.

There are many ways to arrange the safety rope 50 . In some embodiments, as shown in FIG. 7 , the safety rope 50 is arranged along the transmission chain 33 , and the safety rope 50 is inserted into the transmission chain 33 .

The extension path of the safety rope 50 is the same as that of the transmission chain 33, and the safety rope 50 is inserted into the transmission chain 33. The length of the safety rope 50 can be greater than the length of the transmission chain 33. When the connector 40 is not broken, the transmission chain 33 It bears the gravity of the load-bearing part 20 and the counter-weight part 34 and can suspend the load-bearing part 20 and the counter-weight part 34. The safety rope 50 is not subject to the pulling force of the load-bearing part 20 and the counter-weight part 34. The safety rope 50 can follow the transmission chain 33. After the connecting piece 40 breaks, the transmission chain 33 no longer bears the load-bearing member 20 and the counterweight 34 and no longer lifts the load-bearing member 20 and the counterweight 34. The safety rope 50 bears the gravity of the load-bearing member 20 and the counterweight 34. , and can suspend the load-bearing part 20 and the counterweight part 34.

The safety rope 50 is arranged along the transmission chain 33 , making the arrangement of the safety rope 50 simple and reducing the risk of safety accidents caused by the safety rope 50 . The safety rope 50 is inserted into the transmission chain 33 so that the safety rope 50 and the transmission chain 33 are integrated together, making the arrangement of the safety rope 50 and the transmission chain 33 more compact and reducing the volume of the hoist 100 .

In other embodiments, the safety rope 50 may also extend along a path different from that of the transmission chain 33 .

The safety rope 50 may also be wound around the outer periphery of the transmission chain 33 , or may have no connection relationship with the transmission chain 33 .

In some embodiments, the elevator 100 further includes a first buffer structure 60 disposed at the counterweight 34 .

There are many forms of the first buffer structure 60. For example, the first buffer structure 60 can be a rubber pad, a spring, a hydraulic structure, a pneumatic structure, etc.

The first buffer structure 60 can be disposed below the counterweight 34 . The first buffer structure 60 can absorb the fall of the counterweight 34 . The first buffer structure 60 can absorb the energy of the fall of the counterweight 34 , thereby reducing the impact on the counterweight. 34 and reduce damage to other structures below the counterweight 34 .

The first buffer structure 60 can also be provided on the counterweight 34 , and the first buffer structure 60 can follow the counterweight 34 to rise and fall. FIG. 7 shows the case where the first buffer structure 60 is provided on the counterweight 34 .

The first buffer member can play a buffering role at the counterweight 34, thereby protecting the counterweight 34 and other structures located below the counterweight 34 when the counterweight 34 falls, thereby reducing the risk of safety accidents. .

In some embodiments, the elevator 100 further includes a second buffer structure (not shown in the figure), and the second buffer structure is disposed at the bearing member 20 .

The form of the second buffer structure may refer to the first buffer structure 60. For example, the second buffer structure may be a rubber pad, a spring, a hydraulic structure, a pneumatic structure, etc.

The second buffer structure can be disposed below the bearing member 20 , and the fall of the bearing member 20 can be absorbed by the second buffer structure. The second buffer structure can absorb the energy of the fall of the bearing member 20 and the target piece placed on the bearing member 20 , thereby Damage to the bearing member 20 and the target piece is reduced, as well as damage to other structures below the bearing member 20.

The second buffer structure can also be provided on the bearing member 20 , and the second buffer structure can rise and fall following the bearing member 20 .

As shown in Figures 8 and 9, in some embodiments, the elevator 100 also includes a first detection part 70. The first detection part 70 is used to obtain a first signal indicating that the transmission chain 33 is broken; the driving part 31 responds to the first A signal to stop working.

It should be noted that the rupture of the transmission chain 33 may be caused by the transmission chain 33 itself breaking into multiple parts due to external force, so that the transmission chain 33 cannot carry the counterweight 34 and the load-bearing member 20 . The first detection component 70 can detect the breakage of the transmission chain 33 itself, thereby obtaining a first signal indicating the breakage of the transmission chain 33 .

The transmission chain 33 may also be broken due to the fracture of the overloaded connecting member 40 , causing the transmission chain 33 to be unable to bear the gravity of the counterweight 34 and the bearing member 20 . The first detection component 70 may also detect the breakage of the connecting member 40 to obtain the first signal indicating the breakage of the transmission chain 33 .

After the transmission chain 33 is broken, the driving part 31 cannot sense it. If the driving part 31 continues to work, the driving part 31 will idle, which is ineffective and consumes energy and production time. It may even cause the sprocket 32 to rotate due to the breakage. The transmission chain 33 is entangled in the sprocket 32 and may eventually cause the driving member 31 to be overloaded and burned out.

The first detection part 70 can detect the first signal indicating the breakage of the transmission chain 33 after the transmission chain 33 is broken. The control system sends a stop command to the driving part 31 according to the first signal, and the driving part 31 stops working.

When the transmission chain 33 is broken, the first detection part 70 can obtain this signal, that is, the first signal. The driving part 31 responds to the first signal to stop working, and the driving part 31 is reduced to continue working when the transmission chain 33 is broken. Risk of safety accidents.

The first detection component 70 may have various structural forms. For example, the first detection component 70 may be a touch sensor, or the first detection component 70 may be a photoelectric sensor. In some embodiments, the first detection component 70 includes a receiver 71 and a transmitter 72 , the receiver 71 and the transmitter 72 are spaced apart, and at least part of the transmission chain 33 is located between the receiver 71 and the transmitter 72 , the receiver 71 It is used to receive the signal sent by the transmitter 72 after the transmission chain 33 is broken.

The signal emitted by the transmitter 72 may be an optical signal. The receiver 71 can receive the signal sent by the transmitter 72 and feed it back to the control system. The part of the transmission chain 33 between the transmitter 72 and the receiver 71 can block the signal from the transmitter 72 from being transmitted to the receiver 71. In other words, the part of the transmission chain 33 between the receiver 71 and the transmitter 72 blocks reception. The transmitter 71 receives the signal from the transmitter 72. When the transmission chain 33 is broken, the transmission chain 33 may fall, causing the transmission chain 33 to be separated from the receiver 71 and the transmitter 72 and lose its blocking effect on the signal sent by the transmitter 72. The receiver 71 receives the signal sent by the transmitter 72. signal, so that the first detecting component 70 obtains the first signal indicating that the transmission chain 33 is broken. The control system sends a signal to the driver according to the first signal The component 31 issues a stop command, thereby causing the driving component 31 to stop working.

At least part of the transmission chain 33 is located between the receiver 71 and the transmitter 72. Before the transmission chain 33 breaks, the transmission chain 33 blocks the signal sent by the transmitter 72 from being received by the receiver 71; if the transmission chain 33 breaks, the transmission chain 33 It cannot prevent the signal from the transmitter 72 from being received by the receiver 71. After the receiver 71 receives the signal from the transmitter 72, the first detection part 70 obtains the first signal that the transmission chain 33 is broken, and the driving part 31 responds to the first signal. To stop working, the risk of safety accidents caused by the driving member 31 continuing to work when the transmission chain 33 is broken is reduced.

Please continue to refer to Figures 8 and 9. In some embodiments, the driving mechanism 30 includes a plurality of transmission chains 33, and the elevator 100 includes a plurality of first detection parts 70. The first detection parts 70 and the transmission chains 33 are arranged in one-to-one correspondence. .

Multiple includes two or more.

In some embodiments, both ends of each transmission chain 33 are connected to the bearing member 20 and the counterweight 34 respectively, and each transmission chain 33 is connected to the bearing member 20 through a connecting member 40 and/or each transmission chain 33 passes through A connecting piece 40 is connected to the counterweight 34 . Of course, it is also possible that part of the transmission chain 33 is connected to the load-bearing member 20 through a connecting member 40 and/or connected to the counterweight 34 through a connecting member 40 , and the other part of the transmission chain 33 is directly connected to the counterweight 34 and the load-bearing member 20 . Multiple transmission chains 33 jointly carry the weight of the counterweight 34 , the load-bearing member 20 and the target piece placed on the load-bearing member 20 , which can reduce the load-bearing pressure of each transmission chain 33 , thereby extending the service life of the transmission chain 33 and reducing the transmission cost. The risk of safety issues caused by chain 33 breakage.

In the embodiment in which the hoist 100 includes the safety rope 50 , the number of the safety ropes 50 may be multiple, and the safety ropes 50 and the transmission chain 33 are arranged in one-to-one correspondence.

There may also be multiple driving parts 31 and sprockets 32 . The driving parts 31 and the transmission chain 33 are arranged in one-to-one correspondence, and the sprockets 32 and the driving parts 31 are arranged in one-to-one correspondence. Multiple driving members 31 , multiple sprockets 32 and multiple transmission chains 33 jointly drive the bearing member 20 up and down, so the load of each driving member 31 is smaller, which prolongs the service life of the driving member 31 . It can also be understood as multiple drives. The mechanisms 30 jointly drive the bearing member 20 to rise and fall.

If part of the transmission chain 33 is broken, only the driving part 31 corresponding to part of the transmission chain 33 can bear all the gravity of the load-bearing part 20 , which may cause the driving part 31 of this part to be overloaded. If the control system controls the driving part 31 to stop working after the first detection part 70 obtains the first signal, it can also protect the driving part 31 .

The first detection part 70 is used to obtain the first signal indicating that the corresponding transmission chain 33 is broken. The control system can issue a stop command to the driving part 31 according to the first signal obtained by any first detection part 70 to stop the driving part 31 Work.

The first detection part 70 and the transmission chain 33 are arranged in one-to-one correspondence. If any transmission chain 33 breaks, the first detection part 70 corresponding to the broken transmission chain 33 can obtain the first signal, thereby causing the driving part 31 to stop working. The safety performance of the hoist 100 is further improved.

Of course, in other embodiments, the number of the transmission chain 33 may also be one.

As shown in Figures 6, 10, 11, and 12, in some embodiments, the elevator 100 further includes a second detection component 80. The second detection component 80 is used to obtain a second signal characterizing the posture of the bearing component 20. ; The driving member 31 responds to the second signal to stop working.

The posture of the carrier 20 includes but is not limited to whether the carrier 20 is tilted, whether the carrier 20 is rocking, and whether the carrier 20 is twisted. Different second detection parts 80 can be selected for different postures. For example, in an embodiment in which the driving mechanism 30 includes multiple transmission chains 33, if part of the transmission chains 33 is broken, the carrier 20 may tilt, and the second signal indicates that the carrier 20 is tilted, and the second detection component 80 may be able to A detection member that senses the inclination of the carrier member 20 . As shown in Figures 10 and 12, the second detection component 80 includes a sensing component 81 and a detecting component 82. The sensing component 81 and the detecting component 82 are installed at intervals on the carrier 20. When the posture of the carrier 20 is normal, the detector 82 The distance between the detection part 82 and the sensing part 81 enables the detection part 82 to always sense the sensing part 81. If the posture of the bearing part 20 is abnormal, the distance between the detection part 82 and the sensing part 81 may change, causing the sensing part 81 and the detection part to If the distance between 82 is too close or too far, the detection element 82 cannot sense the sensing element 81 , and the second detection element 80 acquires the second signal. The control system sends a stop command to the driving member 31 according to the second signal, so that the driving member 31 stops working. For example, in an embodiment in which the driving mechanism 30 includes multiple transmission chains 33, if part of the transmission chain 33 is broken, the safety rope 50 in the broken transmission chain 33 bears the gravity of the bearing member 20 and the counterweight 34, Then the safety rope 50 and the broken transmission chain 33 jointly carry the load-bearing member. 20 and the counterweight 34, the load-bearing member 20 will bear a greater pulling force at the moment the transmission chain 33 breaks. Since the length of the safety rope 50 is greater than the length of the transmission chain 33, this pulling force may cause the load-bearing member 20 to twist. , thereby causing the distance between the detection component 82 and the sensing component 81 to change. The second detection part 80 may also include a binding part 83. The binding part 83 connects the detection part 82 and the sensing part 81 to make the distance between the detection part 82 and the sensing part 81 more stable. It is necessary to overcome the binding force of the binding part 83 to make the distance between the detection part 82 and the sensing part 81 more stable. The distance between the sensing part 81 and the detecting part 82 changes. The restraint 83 may be a spring, a rope, or the like.

During the normal lifting process of the load-bearing member 20 of the elevator 100, only the height position of the load-bearing member 20 changes. If the second detection member 80 acquires the second signal representing the attitude of the load-bearing member 20, it means that at least part of the elevator 100 If a structural failure occurs, the driving part 31 stops working, thereby reducing the risk of safety accidents caused by the driving part 31 continuing to work when some mechanisms of the hoist 100 fail.

In some embodiments, the elevator 100 further includes at least one side sealing plate (not shown in the figure). The side sealing plate is installed on the frame 10 . The at least one side sealing plate and the frame 10 jointly form a lifting channel. The load bearing member 20 Configured for lifting in the lifting channel.

The side sealing plates are fixed to the frame 10 . The side sealing plates form the walls of the lifting channel, enabling the carrying member 20 to be lifted and lowered in a relatively closed space.

The side sealing plate and the frame 10 jointly form a lifting channel for the lifting and lowering of the bearing 20, which can provide safety protection for both the operator and the target parts on the bearing 20, and improve the safety performance of the hoist 100.

In some embodiments, the frame 10 has an entry and exit area and a non-entry and exit area, and the side sealing plate is provided in the non-entry and exit area; the elevator 100 also includes a third detection part (not shown in the figure), and the third detection part Used to detect a third signal indicating the movement of at least one side sealing plate relative to the frame 10; the driving member 31 responds to the third signal to stop working.

The entry and exit area is the location where the target parts enter and exit the lifting channel. The target piece can be placed on the carrier 20 (loading) and the target piece can be detached from the carrier 20 and leave the lifting channel (unloading) through the loading and unloading area. The inlet and outlet area can form an opening, and there can be one or more openings. Target pieces can also enter and exit the lift tunnel from different openings. Of course, in an embodiment with multiple openings, the target piece can enter and move out of the lifting channel from different openings. For example, the inlet and outlet area forms two opposite openings, and one opening is used for the target piece to enter the lifting channel. Another opening allows the target to be moved out of the lift channel.

In some embodiments, a switch wall may be provided in the loading and unloading area, and the switch wall may be movably mounted on the frame 10 . The switch wall moves relative to the frame 10 to open or close the opening, making it easier for target parts to enter or move out of the lifting channel. The switch wall can rotate or move linearly relative to the frame 10 .

The non-discharging area is other areas of the frame 10 except the discharging and discharging areas. The side sealing plate is installed in the non-inlet and outlet area. Since the target parts do not enter and exit the lifting channel from the non-entry/exit area, and the maintenance of the structure in the lifting channel can also be carried out through the access/exit area. Therefore, the side sealing plate does not need to be disassembled. If the side sealing plate is disassembled to enter the lifting channel, it is an abnormal disassembly and may cause a safety accident.

When the third detection component obtains the third signal indicating that the side sealing plate moves relative to the frame 10, if the driving mechanism 30 is in the standby disabled state, the control system sends a work prohibition instruction to the driving component 31 based on the third signal, and the side sealing plate is lowered. The driving mechanism 30 can only work after the sealing plate is disassembled, which may lead to the risk of safety accidents. For example, if a worker disassembles the side sealing plate and enters the lifting channel from the position where the side sealing plate is removed, if the driving mechanism 30 cannot sense that a worker enters the lifting channel after disassembling the side sealing plate and starts working, the worker may be in danger.

When the third detection part obtains the third signal indicating that the side sealing plate moves relative to the frame 10, if the driving mechanism 30 is in the working state, that is, driving the carrier 20 to rise and fall, the control system sends a message to the driving part 31 to stop working according to the third signal. instruction to stop the driving member 31 from working, thereby reducing the risk of safety accidents caused by the driving mechanism 30 continuing to work after the side sealing plate is removed. For example, if a worker disassembles the side sealing plate and enters the lifting channel from the position where the side sealing plate was removed, if the driving mechanism 30 cannot sense that a worker enters the lifting channel after disassembling the side sealing plate and continues to work, the worker may be in danger.

When the control system sends a prohibition or stop operation to the driving part 31, the control system can also send relevant warning information and warning sounds to the staff, such as buzzers, alarms, etc.

If the side sealing plate is located in the non-inlet and outlet area, the side sealing plate cannot move relative to the frame 10. If the side sealing plate moves relative to the frame 10, there is a risk of abnormal disassembly and safety problems. The third detection piece can be set in When the side sealing plate moves relative to the frame 10, the driving member 31 stops working, thereby reducing the risk of safety accidents.

There are many structural forms of the third detection component. For example, the third detection component can be a photoelectric sensor, a touch sensor, etc. Illustratively, the third detection component is a touch sensor. The third detection component includes a mounting base, a first triggering part, a spring, and a second triggering part. The mounting base is installed on the frame 10 , and the first triggering part is installed on the mounting base. , the second triggering part is connected to the mounting base through a spring. When the side sealing plate is installed on the frame 10, the side sealing plate contacts the second triggering part, and the side sealing plate causes the second triggering part to compress the spring and then contact the first triggering part. external contact. If the first trigger part and the second trigger part contact, it means that the side sealing plate is installed on the frame 10 . If the first trigger part and the second trigger part are separated, it means that the side sealing plate moves relative to the frame 10 or is removed from the frame 10. The third detection part obtains the third signal, and the control system sends a signal to the driving part 31 according to the third signal. Send a work prohibition order or a stop work order.

If any one of the first detection part 70 , the second detection part 80 and the third detection part obtains the relevant signal, no matter what state the driving part 31 is in, the control system will issue a stop command for the driving part 31 and output an alarm at the same time. Information prompts and warning beeps. And check and troubleshoot the fault of the hoist 100.

In addition, under normal operating conditions of the hoist 100, the actual load rate of the driving part 31 will fluctuate within a certain range within the maximum load rate. If a sudden change in the load rate is detected and the fluctuation value is maintained for more than 2 seconds, it can be inferred that an abnormality has occurred in the external load. , the operation of the driving part 31 should be stopped, and the operation of the driving part 31 can be stopped and the fault inspection and troubleshooting work of the hoist 100 can be carried out.

Under normal operation of the hoist 100, there is a preset time monitoring of the current load-bearing part 20 reaching the target height, and it is started synchronously with the operation of the driving part 31 and runs independently. When the load-bearing part with the target height moves from the current height position to the target height position, it is completed. When the duration of all action processes exceeds the preset time, it can be inferred that either the target height position is wrong, or an abnormality occurs in the external load, the operation of the driving part 31 can be stopped and the fault inspection and troubleshooting work of the hoist 100 can be carried out.
