Description

Technical Field

[0001] This application relates to the field of hoisting technology, and in particular to a wire rope tensioning device and a battery swapping station. Background Technology

[0002] Electric trucks (such as heavy trucks and light trucks) are equipped with a lot of batteries, which take a long time to charge. When the battery power is low, the vehicle can be driven into a battery swapping station to replace the battery, shortening the time and ensuring the vehicle can run normally.

[0003] In the prior art, a battery swapping station includes a battery swapping station trolley and a lifting mechanism. The lifting mechanism includes a drum, a fixed pulley, a movable pulley, and a lifting device. The movable pulley is mounted on the lifting device, which is used to connect to the battery. Both the fixed pulley and the drum are mounted on the battery swapping station trolley. The wire rope goes "up and down" around the drum, passes through the fixed pulley around the battery swapping station trolley, and connects to the movable pulley of the lifting device below. Finally, the end of the wire rope is fixed to the trolley. By winding and unwinding the wire rope, the lifting device is raised and lowered to lift the battery.

[0004] However, when the battery swapping station's lifting device descends to the battery surface, the uneven surface prevents the device from making full contact with the battery, causing the wire rope to become slack. This can lead to the battery tilting or swaying, posing a safety hazard and even causing the equipment to stop and become inoperable. Utility Model Content

The detection component includes a detection element connected to a mandrel and used to detect the movement displacement of the mandrel.

[0011] The control component is electrically connected to both the detection element and the drum. The control component is configured to stop the drum from rotating when the displacement of the spindle is greater than or equal to a preset distance value.

[0056] In existing technology, a battery swapping station includes a swapping station trolley and a lifting mechanism. The lifting mechanism includes a drum, a fixed pulley, a movable pulley, and a lifting device. The movable pulley is mounted on the lifting device, which is used to connect to the battery. Both the fixed pulley and the drum are mounted on the swapping station trolley. The wire rope winds around the drum in an "up-in, down-out" manner, passes through the fixed pulley around the swapping station trolley, and connects to the movable pulley of the lower lifting device. Finally, the end of the wire rope is fixed to the trolley. By winding and unwinding the wire rope, the lifting device is raised and lowered to lift the battery. However, when the lifting device descends to the battery surface, due to the unevenness of the battery surface, the lifting device cannot make full contact with the battery, causing the wire rope to become slack. This can lead to the battery tilting, posing a safety hazard, and even causing the equipment to stop and become inoperable. Moreover, in scenarios where the swapping station has limited space and a compact structure, and where the slack rope length is relatively large and there are multiple rope winding methods, such as the swapping station trolley's wire rope "up-in, down-out" and "down-in, up-out," it is inconvenient to adjust the wire rope after it becomes slack.

[0057] This application provides a wire rope tensioning device and a battery swapping station. The wire rope tensioning device includes: a drum for mounting on a battery swapping station trolley, with a wire rope wound on the drum; at least two pulley assemblies, each pulley assembly including a pulley seat, a spindle, and a pulley, the pulley seat being mounted on the drum, the spindle being slidably mounted on the pulley seat, and the pulley being rotatably sleeved on the spindle, with the wire rope wound on the pulley; a lifting assembly for winding the wire rope wound on the pulley to connect the wire rope to the battery swapping station trolley, the lifting assembly being used to connect to the battery; and an elastic component mounted on the pulley seat, with one end of the elastic component correspondingly connected to the spindle. The wire rope is kept taut by a pulley driven by a spindle via an elastic component. When the lifting device comes into contact with the battery, the wire rope tends to slacken, reducing the pressure on the pulley. The elastic component extends, and the sliding of the spindle presses the pulley against the wire rope, thus maintaining tension and ensuring stable lifting and installation. The elastic component, through its cooperation with the pulley and spindle, ensures the wire rope's tension, and all three components are integrated into the pulley seat, minimizing space requirements. Therefore, this application facilitates automatic adjustment of the wire rope tension for smooth and safe lifting operations.

Figure 1 ; Figure 6 A schematic diagram of the tensioning process of the wire rope tensioning device provided in the embodiments of this application. Figure 2 ; Figure 7 This is a schematic diagram of the structure of the wire rope breaking during the tensioning process of the wire rope tensioning device provided in the embodiments of this application.

[0059] On one hand, this application provides a wire rope tensioning device, comprising: a drum 100 for mounting on a battery swapping station trolley 10, with a wire rope wound on the drum 100; at least two pulley assemblies 200, each pulley assembly 200 including a pulley seat 210, a spindle 220, and a pulley 230, the pulley seat 210 being mounted on the drum 100, the spindle 220 being slidably mounted on the pulley seat 210, and the pulley 230 being rotatably mounted on the spindle 220, the pulley 230 being used to wind the wire rope wound from the drum 100; a lifting assembly 400 for winding the wire rope wound from the pulley 230 to connect the wire rope to the battery swapping station trolley 10, the lifting assembly 400 being used to connect to a battery; and an elastic component 300 on the pulley seat 210, the elastic component 300 being correspondingly connected to one end of the spindle 220, the elastic component 300 driving the pulley 230 through the spindle 220 to keep the wire rope in a tensioned state.

[0060] Specifically, the pulley seat 210 is mounted on the battery swapping station trolley 10. The pulley seat 210 includes a base and two upright plates, which are positioned opposite each other on the base. Guide grooves 211 are provided on the upright plates. A spindle 220 is positioned between the two upright plates and is slidably connected to the guide grooves 211. The spindle 220 is cylindrical, and its cylindrical surface has a mating surface that mates with the guide grooves 211. The base is fixed to the battery swapping station trolley 10 by bolts.

[0061] The mandrel 220 has shoulders at both ends, the width of which is greater than the width of the guide groove 211, serving as a limit for the mandrel ends. The mandrel 220 slides along the extension direction of the guide groove 211. A pulley 230 is rotatably sleeved on the mandrel 220. The pulley 230 is sleeved on the mandrel 220 via bearings, allowing the pulley 230 to rotate around the axis of the mandrel 220. In this embodiment, the number of bearings is not limited; for example, the number of bearings can be one or two.

[0062] The elastic component 300 includes a guide 310, an elastic element 320, and an elastic pressure plate 330. The guide 310 is mounted on the pulley seat 210, and the elastic element 320 is sleeved on the guide 310. One end of the elastic pressure plate 330 is connected to the spindle 220, and the other end is sleeved on the guide 310 and connected to the elastic element 320. For example, the guide 310 is a guide bolt, and the elastic element 320 includes a spring sleeve and a spring. The guide bolt passes through the elastic pressure plate 330 and is fixed to the pulley seat 210 with a lock nut. The spring sleeve is sleeved on the guide screw, and the spring is sleeved on both the spring sleeve and the guide screw. The spring sleeve maintains the spring in a compressed state. The elastic component 300, spindle 220, and pulley 230 are integrated on the pulley seat 210, i.e., on the fixed pulley seat of the battery swapping station lifting system, without increasing the original wheel system's external dimensions, resulting in a compact structure and reduced space occupation. The number of elastic components 300 in this application embodiment is not limited. For example, there are two elastic components 300, which are arranged opposite to each other at both ends of the mandrel 220.

[0063] In this embodiment, the elastic component 300 drives the pulley 230 through the spindle 220 to keep the wire rope taut. That is, when the lifting device 400 comes into contact with the battery, the wire rope tends to loosen, the pressure of the wire rope on the pulley 230 is reduced, the elastic component 300 extends, and the pulley 230 presses the wire rope tightly through the sliding of the spindle 220, thereby keeping the wire rope taut and making the lifting and installation stable.

[0064] In some possible implementations, the wire rope tensioning device provided in this application embodiment includes an elastic component 300 comprising a guide 310, an elastic component 320, and an elastic pressure plate 330. The guide 310 is disposed on the pulley seat 210, the elastic component 320 is sleeved on the guide 310, one end of the elastic pressure plate 330 is connected to the spindle 220, and the other end is sleeved on the guide 310 and connected to the elastic component 320.

[0065] Specifically, the guide member 310 is mounted on the base of the pulley seat 210. The guide member 310 can be a guide bolt. The elastic pressure plate 330 is L-shaped, with one end connected to one end of the spindle 220. The other end of the elastic pressure plate 330 is sleeved on the guide member 310 and connected to the elastic member 320, which is also sleeved on the guide member 310. The elastic member 320 extends or compresses along the extension direction of the guide member 310, causing the spindle 220 to slide along the extension direction of the guide groove 211, facilitating the drive of the pulley 230 to keep the wire rope taut.

[0066] This application does not limit the structure of the guide member 310. For example, the guide member 310 is a guide bolt, the elastic member 320 includes a spring sleeve and a spring, the guide bolt passes through the elastic pressure plate 330 and is fixed on the pulley seat 210 with a lock nut, and the spring sleeve is fitted on the guide screw.

[0067] In some possible implementations, the wire rope tensioning device provided in this application embodiment has a bearing 221 sleeved on a spindle 220, a pulley 230 connected to the bearing 221, flange bushings 222 provided at both ends of the spindle 220, and an elastic pressure plate 330 connected to the end face of the flange bushing 222.

[0068] The mandrel 220 has shoulders at both ends, the width of which is greater than the width of the guide groove 211. These shoulders serve as end-positioning devices, allowing the mandrel 220 to move along the extension direction of the guide groove 211 without disengaging from it. Flange sleeves 222 are provided at both ends of the mandrel 220. An elastic pressure plate 330 is connected to the end face of the flange sleeve 222, enabling the mandrel 220 and the elastic element 320 to move synchronously via the elastic pressure plate 330.

[0069] In some possible implementations, the wire rope tensioning device provided in this application embodiment further includes a detection component 500 and a control component 700. The detection component 500 includes a detection element 510, which is connected to the spindle 220 and is used to detect the movement displacement of the spindle 220. The control component 700 is electrically connected to both the detection element 510 and the drum 100. The control component 700 is configured to control the drum 100 to stop rotating when the movement displacement of the spindle 220 is greater than or equal to a preset distance value.

[0070] Specifically, the pulley seat 210 is provided with a mounting component 520, which is detachably connected to the pulley seat 210, for example, by bolts. The mounting component 520 is provided with a moving groove 521, and the detection component 510 is disposed in the moving groove 521 and connected to the spindle 220.

[0071] The detection component 510 includes a sensor and a sensor detection baffle. The sensor is disposed within a movable groove 521, and the sensor detection baffle is fixed to a spindle by pressure plate bolts, allowing it to slide up and down with the spindle. The sensor is fixed to the lower end of the movable groove 521, with its detection port facing the sensor detection baffle. When unloaded or with the battery suspended, the spring is compressed to its maximum compression state, and the corresponding sensor detection baffle is at the lowest point of its sliding stroke, directly facing the sensor detection port, allowing the sensor to detect a signal.

[0072] When the lifting device 400 is lowered to the upper surface of the battery, due to the unevenness of the battery surface, the steel wire rope wound around the movable pulley at the point where the lower surface of the lifting device 400 first contacts the upper surface of the battery tends to slack. At this time, the elastic element 320 recovers its deformation and extends, causing the spindle 220 to be lifted and moved upward a certain distance. The sensor detection baffle moves upward with the spindle 220. The sensor detection baffle has a certain detection height. The upward movement of a certain range is still within the detection range of the sensor detection port. When it exceeds this height, the sensor cannot detect a signal, and the slack rope or broken belt triggers an alarm.

[0073] It should be noted that the elastic coefficient of the elastic element 320 can be designed according to the actual situation. For example, the weight of the lifting device 400 can compress the elastic element 320 to the maximum deformation. That is, when the lifting device 400 is unloaded, the spindle 220 is compressed to the bottom of the guide groove 211 of the pulley seat 210, and when the lifting device 400 is fully loaded, it is also at the bottom of the guide groove 211 of the pulley seat 210.

[0074] Only when the rope is slack (such as when the lifting device 400 is in contact with the battery) does the elastic force of the elastic element 320 exceed the weight of the pulley 230, spindle 220 and bearing 221, causing the elastic element 320 to extend and push the pulley 230 upward, thereby automatically tightening the wire rope.

[0075] When the displacement of the spindle 220 is greater than or equal to the preset distance value, that is, when the wire rope is slack beyond the adjustable length or a rope breakage occurs, the pulley 230 is lifted to the top of the guide groove 211 of the pulley seat 210. When the pulley 230 is at the top of the guide groove 211 of the pulley seat 210, the sensor has no signal. At this time, the slack rope fault or rope breakage fault is triggered to realize the slack rope protection and rope breakage alarm functions, and control the drum 100 to stop rotating.

[0076] In some possible implementations, the wire rope tensioning device provided in this application embodiment has a guide groove 211 provided on the pulley seat 210, and the spindle 220 is slidably connected to the guide groove 211; the detection component 500 includes a mounting member 520, the mounting member 520 has a moving groove 521, one end of the detection member 510 is disposed in the moving groove 521; the other end of the detection member 510 is connected to one end of the spindle 220, and the moving direction of the detection member 510 along the moving groove 521 is parallel to the sliding direction of the spindle 220 along the guide groove 211.

[0077] The detection component 510 includes a sensor and a sensor detection baffle. The sensor is disposed in a movable groove 521, wherein the movable groove 521 is an oblong hole, which can adjust the installation height of the sensor, thereby adjusting the detection range.

[0078] The sensor detection baffle is fixed to the spindle by pressure plate bolts and can slide up and down with the spindle. The sensor is fixed to the lower end of the moving slot 521, with the sensor's detection port facing the sensor detection baffle. When unloaded or with the battery suspended, the spring is compressed to its maximum state, and the corresponding sensor detection baffle is at the lowest point of its sliding stroke, directly facing the sensor's detection port, and the sensor detects a signal.

[0079] The embodiments of this application do not limit the structure of the sensor. For example, the sensor is a proximity switch.

[0080] The sensor detection baffle can slide up and down with the mandrel 220, and the change in the height of the sensor detection baffle indicates the range of slack length of the wire rope. The sensor detection baffle slides straight up and down, increasing the slack detection range. It can be understood that the wire rope tensioning device provided in this embodiment adopts an up-and-down sliding method, rather than a horizontal or oblique structure, to increase the slack detection length range.

[0081] In some possible implementations, the wire rope tensioning device provided in this application embodiment has a drum 100 having at least two rope outlet ends 110, the two rope outlet ends 110 being arranged opposite to each other and having opposite rope outlet directions, and each rope outlet end 110 being correspondingly connected to each pulley assembly 200.

[0082] Specifically, a drum 100 and two pulley assemblies 200 are set up accordingly, and the rope exit directions of the rope ends 110 are opposite, so as to simultaneously realize the top-in-bottom-out rope winding method and the bottom-in-top-out rope winding method of the drum 100.

[0083] In some possible implementations, the wire rope tensioning device provided in this application embodiment also includes a protective component 600, which is mounted on the pulley 230 to prevent the wire rope on the pulley 230 from jumping.

[0084] Specifically, the protective component 600 is mounted on the pulley 230, and both ends of the protective component 600 are connected to the pulley seat 210. The wire rope is located between the protective component 600 and the pulley 230 to prevent the wire rope on the pulley 230 from jumping. The wire rope tensioning device in this embodiment of the application simultaneously realizes the functions of slack rope protection and automatic wire rope tensioning, and is integrated into the pulley seat 210 of the battery swapping station trolley, saving space, facilitating installation, and ensuring safety and reliability.

[0085] The wire rope tensioning device provided in this application embodiment includes a protective component 600 comprising two brackets 610 and a protective element 620. The two brackets 610 are arranged opposite to each other and are connected to the protective element 620. The wire rope is located between the protective element 620 and the pulley 230.

[0086] The protective component 620 includes a fixed-distance long bolt and a fixed-distance sleeve. The fixed-distance sleeve is fitted onto the fixed-distance long bolt. The bracket 610 is provided with a connecting hole. The long bolt passes through the connecting hole and is connected to the long bolt by a nut, thereby fixing the fixed-distance sleeve between the brackets 610. A steel wire rope passes between the fixed-distance sleeve and the pulley to prevent the steel wire rope from detaching from the groove of the pulley 230.

[0087] In some possible implementations, the wire rope tensioning device provided in this application embodiment, the lifting device assembly 400 includes a pulley 410, a connecting plate 420 and a connector 430. The pulley 410 is disposed on the connecting plate 420, and the connector 430 is disposed on the side of the connecting plate 420 away from the pulley 410. The connector 430 is used to connect to a battery.

[0088] The pulley assembly 410 includes multiple movable pulleys, and the connecting member 430 is a clamp and a connecting plate. Each movable pulley is connected to each pulley 230. The wire rope wound from one end of the drum 100 passes around the pulley 230, through the movable pulley, and is fixed to the side of the battery swapping station trolley 10 away from the pulley 230. The wire rope wound from the other end of the drum 100 passes around another pulley 230, through another movable pulley, and is fixed to the side of the battery swapping station trolley 10 away from the pulley 230. By winding and unwinding the wire rope, the lifting device assembly 400 is raised and lowered, and the lifting device assembly 400 is convenient for connecting and lifting batteries.
