Description

Technical Field

[0001] The utility model relates to an anti-falling device and battery transport equipment comprising the same. Background Art

[0002] When replacing batteries for existing electric vehicles, it is usually necessary to remove the depleted battery pack from the electric vehicle and transport it to the charging rack, and remove the fully charged battery pack from the battery compartment of the charging rack and transport it to the electric vehicle. The charging rack usually stores batteries in a stacked form, so when the battery transport equipment takes out or places the batteries, it is necessary not only to move the car in the horizontal direction, but also to move the car in the vertical direction.

[0003] If the car fails, stalls or loses power during vertical movement, it will cause the car to fall out of control or even free fall, thus damaging the battery transport equipment. The battery pack on the battery transport equipment will also be damaged, and in severe cases, it may even cause deflagration and explosion after the battery pack is damaged. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the battery transfer equipment lacks safety protection after a malfunction or power failure, and may fall out of control, causing damage to the battery transfer equipment and the battery pack, thereby creating a safety hazard. An anti-fall device and a battery transfer equipment containing the same are provided.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model provides an anti-falling device for use in a battery transport device, wherein the battery transport device comprises a lift that can be lifted and moved and is used to carry a battery pack, and the anti-falling device comprises:

[0007] a trigger assembly, disposed on the battery transport device and located on one side of the car, the trigger assembly being configured to rise and fall at a preset speed simultaneously with the car;

[0008] A limit assembly cooperates with the trigger assembly and is connected to the car. The limit assembly has a first state and a second state. When the descending speed of the car is higher than the preset speed, the trigger assembly drives the limit assembly to switch from the first state to the second state to limit the descent of the car.

[0009] In the present solution, the above-mentioned structural form is adopted. Once the car falls out of control or even freely falls, the falling speed of the car accelerates, causing the limit assembly connected to the car to descend faster than the descending speed of the trigger assembly, and then the limit assembly is pulled by the trigger assembly and switched to the second state, thereby achieving emergency braking of the car, avoiding the situation where the car stalls and causes damage to the battery transfer equipment or battery pack, and avoiding safety hazards.

[0010] Preferably, the limit assembly comprises a clamping column and a clamping assembly, the clamping assembly is connected to one side of the car, and the clamping column is arranged opposite to the clamping assembly and is located outside the car;

[0011] When the limiting assembly is in the first state, the clamping assembly is separated from the clamping column; when the limiting assembly is in the second state, the clamping assembly cooperates with the clamping column to limit the descent of the car.

[0012] In this solution, the above-mentioned structural form is adopted, and emergency braking is achieved when the car stalls and falls due to a malfunction through the cooperation between the clamping column and the clamping assembly, which is safe and reliable.

[0013] Preferably, the clamping column is provided with a clamping groove, and the clamping assembly includes a protruding rod, and the protruding rod is connected to the trigger assembly;

[0014] The extension rod is configured so that when the limit assembly is in the first state, the extension rod remains in the initial position and is disengaged from the clamping column; when the car descends at a speed higher than the preset speed, the trigger assembly drives the extension rod to move to cooperate with the clamping groove so that the limit assembly is in the second state.

[0015] In this solution, the above-mentioned structural form is adopted, and the emergency braking of the car is achieved through the cooperation between the extension rod and the clamping groove. The braking effect is stable and the car is prevented from falling off the battery transfer equipment.

[0016] Preferably, the clamping assembly includes a mounting frame and a linkage plate, the extension rod is arranged in the mounting frame and connected to the linkage plate, and the upper end of the linkage plate is connected to the trigger assembly;

[0017] When the descending speed of the car is higher than the preset speed, the trigger assembly pulls the linkage plate to move upward relative to the mounting frame, and the linkage plate pushes the extension rod toward the clamping groove during the movement.

[0018] In this solution, the above-mentioned structural form is adopted, and the trigger component is used to drive the linkage plate and the extension rod to move in sequence, thereby realizing the extension of the extension rod to cooperate with the card slot. This design has a simple overall structure and high reliability.

[0019] Preferably, a guide groove is provided on the linkage plate, and the guide groove is arranged obliquely from top to bottom along the insertion direction of the extension rod into the clamping groove;

[0020] The mounting frame is provided with a horizontal groove, and the horizontal groove extends along the insertion direction of the extension rod into the clamping groove;

[0021] A guide column is provided on the extension rod, and at least a part of the guide column is accommodated in the guide groove and the horizontal groove at the same time.

[0022] In the present solution, the above-mentioned structural form is adopted. When the linkage plate is pulled upward by the trigger assembly relative to the mounting frame, the guide column on the extending rod is driven to slide in the guide groove. Under the limitation of the horizontal groove, the guide column simultaneously moves in the horizontal groove along the extension direction of the horizontal groove to drive the extending rod to move in the horizontal direction toward the snap-in groove and thus enable the extending rod to be inserted into the snap-in groove. Through the mechanical structure rather than in an electrical environment, the control is reliable and the possibility of failure can be reduced or avoided.

[0023] Preferably, the snap-on assembly also includes a connecting piece, the two ends of which are respectively connected to the linkage plate and the mounting frame, and the connecting piece is configured so that the linkage plate can break or deform when the linkage plate is pulled by the trigger assembly to achieve relative movement between the linkage plate and the mounting frame.

[0024] In this solution, the above-mentioned structural form is adopted, and the two ends of the connecting piece are respectively connected to the linkage plate and the mounting frame, so that when the car is normally raised and lowered and the trigger assembly does not pull the linkage plate, the linkage plate is prevented from moving relative to the mounting frame, thereby ensuring that the extending rod will not be inserted into the card slot.

[0025] Preferably, a sliding groove is provided in the mounting frame, the extending rod is placed in the sliding groove, and the sliding groove extends along an insertion direction of the extending rod into the clamping groove.

[0026] In this solution, the above-mentioned structural form is adopted to limit the extension direction of the extension rod through the sliding groove, thereby reducing or avoiding the possibility that the extension rod cannot be connected with the clamping groove after being extended.

[0027] Preferably, the mounting frame is provided with a notch portion penetrating vertically, and the linkage plate is placed in the notch portion and can move up and down in the notch portion.

[0028] In this solution, the above-mentioned structural form is adopted, and the notch portion is provided to avoid contact interference between the linkage plate and the mounting frame during the up and down movement, and the movement direction of the linkage plate can also be restricted.

[0029] Preferably, the anti-fall device includes a fixed rod extending up and down, the fixed rod is installed on the battery transfer equipment, and the trigger component is configured to be slidably connected to the fixed rod when the car is raised or lowered at the preset speed; the trigger component is configured to self-lock and cannot slide relative to the fixed rod when the descending speed of the car is higher than the preset speed.

[0030] In this solution, the above-mentioned structural form is adopted. When the limit assembly is triggered by the trigger assembly and switches from the first state to the second state, the trigger assembly switches to a self-locking state relative to the fixed rod and cannot slide relative to the fixed rod to pull, further ensuring that the limit assembly switches between the first state and the second state. When the car is normally lifted, the trigger assembly is slidably connected relative to the fixed rod to reduce or avoid the blockage of the trigger assembly during the lifting process, thereby avoiding the obstruction of the car descent; when the car stalls and falls, the car falls faster and drives the limit assembly faster than the trigger assembly, so that the limit assembly switches from the first state to the second state after being triggered by the trigger assembly to limit the car from continuing to fall; at the same time, the trigger assembly is self-locked and fixed on the fixed rod, so that when the limit assembly switches to the second state, even if the extension rod does not cooperate with the clamping groove in the first time, the limit assembly can be pulled by the self-locking of the trigger assembly to prevent the car from further falling. Such a design realizes secondary protection to limit the car from continuing to fall.

[0031] Preferably, the trigger assembly includes a connecting rod, which is configured to rotate and press against the fixed rod to self-lock when the car descending speed is higher than the preset speed, and pull the limit assembly to switch to the second state.

[0032] In the present scheme, the above-mentioned structural form is adopted. When the car is normally raised or lowered, the car, the trigger assembly and the limit assembly are raised or lowered synchronously at a preset speed; once the car stalls and falls, the car accelerates to fall, driving the limit assembly to descend faster than the trigger assembly, and the limit assembly is triggered by the trigger assembly to switch from the first state to the second state to limit the descent of the car; in addition, the connecting rod connected to the limit assembly rotates under the action of the gravity of the car and presses against the fixed rod to achieve self-locking of the trigger assembly relative to the fixed rod, thereby being able to pull the limit assembly to further prevent the car from descending, with fast response and high reliability.

[0033] Preferably, the anti-fall device further comprises a detection mechanism, which is disposed at the upper end of the mounting frame and is configured to control the motor connected to the car to stop running when the linkage plate moves relative to the mounting frame.

[0034] In the present solution, the above-mentioned structural form is adopted, and a detection mechanism is set up to feedback to the motor after detecting the linkage plate so that the car stops moving, which has high safety. In addition, if the limit assembly switches to the second state due to false triggering, the car can also stop moving by stopping the motor, thereby preventing the motor from continuing to run and driving the car to fall further, causing the limit assembly to be damaged.

[0035] Preferably, there are a plurality of the clamping grooves, and the plurality of the clamping grooves are arranged at intervals along a height direction of the clamping column.

[0036] In this solution, the above-mentioned structural form is adopted, and a plurality of clamping grooves are arranged on the clamping column. As long as the extension rod is lowered to a position corresponding to one of the clamping grooves, the clamping can be realized in time, and the response is fast.

[0037] The utility model also provides a battery transport device, which comprises the anti-falling device as described above.

[0038] The positive and progressive effects of the utility model are:

[0039] In the case where the car loses control and even freely falls, the anti-fall device in the utility model accelerates the falling speed of the car, causing the limit assembly connected to the car to descend faster than the descending speed of the trigger assembly, and then the limit assembly is pulled by the trigger assembly and switched to the second state, thereby achieving emergency braking of the car, avoiding the situation where the battery transfer equipment or battery pack is damaged due to car stalling, and avoiding safety hazards.

[0081] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0082] Please combine Figures 1 to 11For understanding, an embodiment of the utility model provides an anti-falling device 1, which is used in a battery transfer device 3, wherein the battery transfer device 3 includes a car 2 which can be raised and lowered and is used to carry a battery pack, and the anti-falling device 1 includes a trigger component 11 and a limit component 12, wherein the trigger component 11 is arranged on the battery transfer device 3 and is located on one side of the car 2, and the trigger component 11 is configured to be raised and lowered at a preset speed simultaneously with the car 2; the limit component 12 cooperates with the trigger component 11 and is connected to the car 2, and the limit component 12 has a first state and a second state, and when the descending speed of the car 2 is higher than the preset speed, the trigger component 11 drives the limit component 12 to switch from the first state to the second state to limit the descent of the car 2. The car 2 is raised and lowered at a preset speed, the trigger component 11 and the car 2 are raised and lowered synchronously, and the limit component 12 is in the first state, which will not affect the lifting and lowering movement of the car 2; when the battery transfer device 3 fails or loses power, the car 2 falls out of control, the falling speed of the car 2 is accelerated, and the limit component 12 connected to the car 2 is driven to descend faster than the trigger component 11, and then the trigger component 11 drives the limit component 12 to switch to the second state to limit the descent of the car 2, thereby realizing the emergency braking of the car 2. In other words, once the car 2 falls out of control or even falls freely, the falling speed of the car 2 is accelerated, driving the limit component 12 connected to the car 2 to descend faster than the trigger component 11, and then the limit component 12 is pulled by the trigger component 11 and switched to the second state, thereby realizing the emergency braking of the car 2, and avoiding the situation where the car 2 stalls and causes damage to the battery transfer device 3 or the battery pack, thereby avoiding safety hazards.

[0083] In this embodiment, if Figure 2 , Figure 7 and Fig.11 As shown, the limit assembly 12 includes a clamping column 121 and a clamping assembly 122, the clamping assembly 122 is connected to one side of the car 2, the clamping column 121 and the clamping assembly 122 are arranged opposite to each other and are located outside the car 2; when the limit assembly 12 is in the first state, the clamping assembly 122 is separated from the clamping column 121; when the limit assembly 12 is in the second state, the clamping assembly 122 cooperates with the clamping column 121 to limit the descent of the car 2. When the car 2 falls normally, the limit assembly 12 is in the first state, the clamping assembly 122 is separated from the clamping column 121, so as not to affect the lifting and lowering movement of the car 2; when the car 2 stalls and falls, the limit assembly 12 switches from the first state to the second state, the clamping assembly 122 cooperates with the clamping column 121 to prevent the clamping assembly 122 connected to the car 2 from moving downward, thereby realizing the emergency braking of the car 2. The cooperation between the clamping column 121 and the clamping assembly 122 can realize emergency braking when the car 2 stalls and falls due to a fault, which is safe and reliable.

[0084] In this embodiment, if Figure 2 , Figure 7 and Fig.11 As shown, the clamping column 121 is provided with a clamping groove 1211, and the clamping assembly 122 includes a protruding rod 1221, which is connected to the trigger assembly 11; the protruding rod 1221 is configured so that when the limit assembly 12 is in the first state, the protruding rod 1221 remains in the initial position and is separated from the clamping column 121; when the descending speed of the elevator car 2 is higher than the preset speed, the trigger assembly 11 drives the protruding rod 1221 to move to match the clamping groove 1211 so that the limit assembly 12 is in the second state. Figure 2 As shown, the car 2 is lifted normally, the limit assembly 12 is in the first state, the extension rod 1221 is disengaged from the clamping column 121, and the matching relationship between the car 2 and the clamping column 121 is released, and the car 2 can be lowered normally; Figure 7 As shown, the car 2 stalls and descends, the limit assembly 12 is in the second state, and the extension rod 1221 cooperates with the clamping groove 1211 to limit the descent of the car 2. The emergency braking of the car 2 is achieved by the cooperation between the extension rod 1221 and the clamping groove 1211, and the braking effect is stable, preventing the car 2 from falling off the battery transfer device 3.

[0085] In this embodiment, if Figures 2 to 10 As shown, the clamping assembly 122 includes a mounting frame 1222 and a linkage plate 1223, the extension rod 1221 is arranged in the mounting frame 1222 and connected to the linkage plate 1223, and the upper end of the linkage plate 1223 is connected to the trigger assembly 11; when the descending speed of the car 2 is higher than the preset speed, the trigger assembly 11 pulls the linkage plate 1223 to move upward relative to the mounting frame 1222, and the linkage plate 1223 pushes the extension rod 1221 toward the clamping groove 1211 during the movement. In other words, when the car 2 stalls and falls, the trigger assembly 11 pulls the linkage plate 1223 out of the mounting frame 1222 to drive the extension rod 1221 to move in the direction close to the clamping column 121 so as to extend into the clamping groove 1211. The trigger assembly 11 drives the linkage plate 1223 and the extension rod 1221 to move in sequence, thereby realizing the push-out of the extension rod 1221 to cooperate with the clamping groove 1211. Such a design has a simple overall structure and high reliability.

[0086] In this embodiment, a guide groove 12231 is provided on the linkage plate 1223, and the guide groove 12231 is inclined from top to bottom along the insertion direction of the protruding rod 1221 into the clamping groove 1211; a horizontal groove 12221 is provided on the mounting frame 1222, and the horizontal groove 12221 extends along the insertion direction of the protruding rod 1221 into the clamping groove 1211; a guide column 12211 is provided on the protruding rod 1221, and at least part of the guide column 12211 is simultaneously accommodated in the guide groove 12231 and the horizontal groove 12221. When the linkage plate 1223 is pulled by the trigger assembly 11 to move upward relative to the mounting frame 1222, the guide column 12211 on the extending rod 1221 is driven to slide in the guide groove 12231. Under the limitation of the horizontal groove 12221, the guide column 12211 simultaneously moves in the horizontal groove 12221 along the extension direction of the horizontal groove 12221, so as to drive the extending rod 1221 to move horizontally toward the clamping groove 1211, thereby enabling the extending rod 1221 to be inserted into the clamping groove 1211. Through the mechanical structure instead of in an electrical environment, the control is reliable, and the possibility of failure can be reduced or avoided.

[0087] In this embodiment, if Figure 2 As shown, the clamping assembly 122 further includes a connecting member 1224, the two ends of which are respectively connected to the linkage plate 1223 and the mounting frame 1222, and the connecting member 1224 is configured so that the linkage plate 1223 can be broken or deformed when the linkage plate 1223 is pulled by the trigger assembly 11, so as to achieve relative movement between the linkage plate 1223 and the mounting frame 1222. The two ends of the connecting member 1224 are respectively connected to the linkage plate 1223 and the mounting frame 1222, so that when the car 2 is normally raised and lowered and the trigger assembly 11 does not pull the linkage plate 1223, the linkage plate 1223 is prevented from moving relative to the mounting frame 1222, thereby ensuring that the extension rod 1221 will not be inserted into the clamping groove 1211.

[0088] Specifically, a steel wire rope is used as a breakable or deformable connecting piece to save costs.

[0089] In this embodiment, if Fig.10 As shown, a sliding groove 12222 is provided in the mounting frame 1222, and the extension rod 1221 is placed in the sliding groove 12222, and the sliding groove 12222 extends along the insertion direction of the extension rod 1221 into the clamping groove. The extension direction of the extension rod 1221 is limited by the sliding groove 12222, reducing or avoiding the possibility that the extension rod 1221 cannot be docked with the clamping groove 1211 after being extended.

[0090] In this embodiment, if Figure 6As shown, a notch 12223 is provided on the mounting frame 1222, and the linkage plate 1223 is placed in the notch 12223 and can move up and down in the notch 12223. When the trigger assembly 11 pulls the linkage plate 1223, the linkage plate 1223 is pulled out of the mounting frame 1222 through the notch 12223. By providing the notch 12223, contact interference between the linkage plate 1223 and the mounting frame 1222 is avoided during the up and down movement of the linkage plate 1223, and the movement direction of the linkage plate 1223 can also be limited.

[0091] Specifically, the mounting frame 1222 includes a first mounting plate 12224 and a second mounting plate 12225, and the first mounting plate 12223 and the second mounting plate 12225 are arranged relative to each other to form an accommodating space, and the extending rod 1221 and the linkage plate 1223 are both accommodated in the accommodating space, wherein a sliding groove 12222 is provided on the side of the first mounting plate 12224 close to the second mounting plate 12225, the extending rod 1221 is installed in the sliding groove 12222 and can slide in the sliding groove 12222, the linkage plate 1223 is placed between the extending rod 1221 and the second mounting plate 12225, and the linkage plate 1223 can move up and down in the notch 12223 between the first mounting plate 12224 and the second mounting plate 12225.

[0092] In this embodiment, if Figure 4 and Figure 5 As shown, the mounting frame 1222 is installed on one side of the car 2 through the mounting side plate 15, and at least one of the upper and lower ends of the mounting frame 1222 is connected to the mounting side plate 15 through an L-shaped mounting block 16, so the installation stability is high.

[0093] In this embodiment, if Figure 2 , 3As shown in Figures 7 and 8, the anti-fall device 1 includes a fixed rod 13 extending up and down, and the fixed rod 13 is installed on the battery transfer device. The trigger component 11 is configured to be slidably connected with the fixed rod 13 when the car 2 is raised or lowered at a preset speed; the trigger component 11 is configured to be self-locked and unable to slide relative to the fixed rod 13 when the descending speed of the car 2 is higher than the preset speed. When the limit component 12 is triggered by the trigger component 11 and switches from the first state to the second state, the movement state of the trigger component 11 relative to the fixed rod 13 is switched to a self-locking state, and it is unable to slide relative to the fixed rod 13 to be pulled, which further ensures that the limit component 12 is switched between the first state and the second state. When the car 2 is normally lifted or lowered, the trigger assembly 11 is slidably connected relative to the fixed rod 13, reducing or avoiding the situation that the trigger assembly 11 is blocked during the lifting process, thereby avoiding the car 2 from being blocked from descending; when the car 2 stalls and falls, the car 2 falls faster, which drives the limit assembly 12 faster than the trigger assembly 11, so that the limit assembly 12 switches from the first state to the second state after being triggered by the trigger assembly 11, so as to limit the car 2 from continuing to descend; at the same time, the trigger assembly 11 is self-locking and fixed on the fixed rod 13, so that when the limit assembly 12 switches to the second state, even if the extension rod 1221 does not cooperate with the clamping groove 1211 in the first time, the limit assembly 12 can be pulled by the self-locking of the trigger assembly 11 to prevent the car 2 from further descending. Such a design realizes a secondary protection to limit the car 2 from continuing to descend.

[0094] In this embodiment, if Figure 2 and Figure 7 As shown, the trigger assembly 11 includes a connecting rod 111, and the connecting rod 111 is configured to rotate and abut against the fixed rod 13 to self-lock when the descending speed of the car 2 is higher than the preset speed, and pull the limit assembly 12 to switch to the second state. When the car 2 is normally lifted and lowered, the car 2, the trigger assembly 11 and the limit assembly 12 are synchronously lifted and lowered at the preset speed; once the car 2 stalls and falls, the car 2 accelerates to drive the limit assembly 12 to descend faster than the trigger assembly 11, and the limit assembly 12 is triggered by the trigger assembly 11 to switch from the first state to the second state to limit the descent of the car 2; in addition, the connecting rod 111 connected to the limit assembly 12 rotates under the gravity of the car 2 and abuts against the fixed rod 13 to achieve self-locking of the trigger assembly 11 relative to the fixed rod 13, and then can pull the limit assembly 12 to further prevent the car 2 from descending, with fast response and high reliability.

[0095] Specifically, the connecting rod 111 is connected to the upper end of the linkage plate 1223 through the connecting member 1224. Figure 3 and Figure 8As shown, the trigger assembly includes a sleeve 112, a connecting rod 111, a second connecting plate 114 and a first connecting plate 113 connected in sequence, the sleeve 112, the connecting rod 111, the second connecting plate 114 and the first connecting plate 113 enclose a frame structure, and the sleeve 112 is sleeved on the outer peripheral side of the fixed rod 13 and is used for sliding connection relative to the fixed rod 13. Figure 3 As shown, the trigger assembly 11 and the car 2 fall synchronously at a preset speed, and the trigger assembly 11 is a rectangular frame structure; Figure 8 As shown, the car 2 loses control and accelerates to fall, and the connecting rod 111 is pulled by the car 2 to rotate relative to the fixed rod 13 and resist the fixed rod 13. At this time, the trigger assembly 11 has a diamond frame structure, and the first connecting plate 113 can also rotate relative to the fixed rod 13 and resist the fixed rod 13, thereby enhancing the fixing effect of the trigger assembly 11 relative to the fixed rod 13.

[0096] In this embodiment, if Figure 4 As shown, the anti-fall device 1 also includes a detection mechanism 14, which is arranged at the upper end of the mounting frame 1222 and is configured to control the motor connected to the car 2 to stop running when the linkage plate 1223 moves relative to the mounting frame 1222. During the upward movement of the linkage plate 1223 relative to the mounting frame 1222, the detection mechanism 14 can detect the linkage plate 1223 and feed back the signal to the control unit to control the motor connected to the car 2 to stop running. By setting the detection mechanism 14, after the linkage plate 1223 is detected, the motor is fed back to stop the car 2 from moving, which is highly safe; in addition, if the limit assembly 12 switches to the second state due to an erroneous trigger, the car 2 can also stop moving by stopping the motor, so as to avoid the limit assembly 12 being damaged due to the continued operation of the motor driving the car 2 to fall further.

[0097] In this embodiment, if Fig.11 As shown, there are multiple clamping grooves 1211, and the multiple clamping grooves 1211 are arranged at intervals along the height direction of the clamping column 121. Multiple clamping grooves 1211 are arranged on the clamping column 121, and as long as the extension rod 1221 drops to a position corresponding to one of the clamping grooves 1211, the clamping can be realized in time, and the response is fast.

[0098] In specific implementation, Figures 2 to 6 As shown, when the car 2 descends at a constant speed at a preset speed, the trigger assembly 11 and the limit assembly 12 also descend synchronously at a constant speed at a preset speed, and the connecting rod 111 is not affected by the gravity of the car 2 and does not rotate relative to the fixed rod 13, so that the trigger assembly 11 has a rectangular frame structure, and the connecting member 1224 pulls the linkage plate 1223 to prevent it from moving relative to the mounting frame 1222, and the extending rod 1221 is placed in the sliding groove 12222 and disengaged from the clamping groove 1211, so that the car 2 can be raised and lowered normally.

[0099] like Figures 7 to 10 As shown, once the car 2 loses control and accelerates to fall, the accelerated fall of the car 2 drives the limit assembly 12 to descend faster than the trigger assembly 11, and the limit assembly 12 is triggered by the trigger assembly 11 to switch from the first state to the second state. The trigger assembly 11 applies an upward pulling force to the linkage plate 1223, so that the linkage plate 1223 moves upward relative to the mounting frame 1222. During this process, the connecting member 1224 is deformed or broken by the force, and the linkage plate 1223 can drive the guide column 12211 on the extension rod 1221 to slide in the guide groove 12231. Under the limitation of the horizontal groove 12221, the guide column 12211 moves along the horizontal groove 12221. The horizontal groove 12221 moves in the extension direction so that the protruding rod 1221 can be inserted into the clamping groove 1211, so that the car 2 is clamped with the clamping column 121, thereby limiting the car 2 from continuing to descend; in the process of the limit assembly 12 switching to the second state, the connecting rod 111 connected to the limit assembly 12 rotates and presses against the fixed rod 13 under the action of the gravity of the car 2 to achieve self-locking of the trigger assembly 11 relative to the fixed rod 13, and the first connecting plate 113 can also rotate relative to the fixed rod 13 and press against the fixed rod 13. At this time, the trigger assembly 11 is a diamond frame structure and is fixed on the fixed rod 13, so that the linkage plate 1223 can be pulled, further limiting the car 2 from continuing to descend.

[0100] like Figure 1 As shown, the embodiment of the utility model further provides a battery transport device 3, which includes a car 2, a column 4 and the anti-fall device 1 as described above. There are at least two columns 4, which are respectively located on both sides of the car 2. The car 2 is connected to the columns 4 and can be raised and lowered relative to the columns 4. The trigger assembly 11 and the limit assembly 12 are installed on the same side of the car 2, the upper end of the fixed rod 13 is fixedly connected to the column 4 located on one side of the car 2 and is arranged opposite to the column 4, the lower end of the fixed plate 13 is fixed to the base of the battery transport device 3, the fixed rod 13 is sleeved with the trigger assembly 11, the clamping column 121 is fixedly connected to the column 4 located on one side of the car 2, and the clamping assembly 122 is installed on the outside of the car 2 and is arranged opposite to the clamping column 121.

[0101] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
