Detailed Implementation Manner

[0033] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0034] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0035] In the embodiments of the present application, unless otherwise clearly defined and limited, a first feature being "on" or "under" a second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, a first feature being "above", "over" and "on top of" a second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. A first feature being "under", "below" and "beneath" a second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0036] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0037] In the related art, there is a lifting device powered by a battery. Using a battery to power the lifting device can solve the defects brought by the trailing cable, but the battery's own endurance is limited, and it is necessary to replenish electrical energy at any time during the intermittent period of using the lifting device. Currently, there are the following two charging methods for the battery of the lifting device.

[0038] The first charging method is that when the car assembly in the lifting device stops at the platform, on-site workers lead the charging power cord over and plug it into the battery in the lifting device for charging; after charging is completed, the workers need to unplug the charging power cord and put away the charging power cord. This charging operation is cumbersome and inconvenient for charging.

[0039] The second charging method is to design the battery as a detachable type. When the battery needs to be charged, on-site personnel remove the battery and charge it separately. After charging is completed, it is reassembled. The disassembly and installation process is relatively cumbersome and inconvenient for charging. For this reason, the embodiments of the present utility model provide a lifting device that can achieve automatic charging when the lifting device stops at the platform, and the charging is relatively convenient.

[0040] Figure 1 is a schematic structural diagram of the lifting device provided by the embodiments of the present utility model. Figure 2 is a partial structural schematic diagram of the lifting device provided by the embodiments of the present utility model. Figure 3 is a schematic structural diagram of the brush plate assembly provided by the embodiments of the present utility model. Figure 4 is a schematic structural diagram of the charging device provided by the embodiments of the present utility model.

[0041] Refer to Figures 1 to 3 , the embodiments of the present utility model provide a lifting device, which includes a guiding assembly 100, a car assembly 200, and a charging device 300.

[0042] The guiding assembly 100 is used to provide an installation platform and support for the car assembly 200 and the charging device 300, and the guiding assembly 100 can also provide a guiding function for the operation of the car assembly 200. Among them, the guiding assembly 100 may include a carrier and a guiding body. The carrier may be a ladder, and the guiding body may be a load-bearing guide rail or an anti-falling guide rail installed on the ladder.

[0043] The car assembly 200 is arranged on one side of the guiding assembly 100 and is movably matched with the guiding assembly 100, and can move up and down along the guiding assembly 100. For example, the car assembly 200 and the guiding assembly 100 can be in rolling cooperation through structures such as guiding wheels and anti-falling wheels, so that the car assembly 200 can move up and down along the extending direction of the guiding assembly 100, and the car assembly 200 will not break away from the guiding assembly 100. A battery module is provided on the car assembly 200, and the battery module is used to provide electrical energy for the car assembly 200. The car assembly 200 can be replaced with a structure such as a non-climbing vehicle body according to actual use needs.

[0044] The charging device 300 includes a charging control component 310 and a charging module 320. The charging control component 310 is adapted to be connected to a power source. The charging module 320 includes a brush plate component 321 and a brush block component 322. One of the brush plate component 321 and the brush block component 322 is arranged on the guiding assembly 100 and is electrically connected to the charging control component 310. The other of the brush plate component 321 and the brush block component 322 is arranged on the car assembly 200 and is connected to the battery module. The brush plate component 321 is adapted to be paired and connected with the brush block component 322 to charge the battery module.

[0045] For example, the brush plate component 321 can be fixed to the outer side wall of the car assembly 200 through structures such as bolts and screws. When the car assembly 200 moves up and down along the guiding assembly 100, it can drive the battery component and the brush plate component 321 to move up and down synchronously. The brush block component 322 is fixed to the guiding assembly 100 by structures such as bolts and screws, and the position of the brush block component 322 located on the guiding assembly 100 remains fixed. When the brush plate component 321 moves up and down with the car assembly 200 and is paired and connected with the brush block component 322, the circuit of the brush block component 322 is turned on, and the battery module is charged through the cooperation of the brush block component 322 and the brush plate component 321, which is relatively convenient for charging.

[0046] Alternatively, the brush block assembly 322 can be fixed to the outer wall of the car assembly 200 by means of structures such as bolts and screws. When the car assembly 200 moves up and down along the guiding assembly 100, it can drive the battery assembly and the brush block assembly 322 to move up and down synchronously. The brush plate assembly 321 is fixed to the guiding assembly 100 by means of structures such as bolts and screws. The position of the brush plate assembly 321 on the guiding assembly 100 remains fixed, and the installation positions of the brush plate assembly 321 and the brush block assembly 322 can be determined according to actual usage requirements.

[0047] It can be understood that for the lifting device provided by the embodiment of the present utility model, by providing a charging device 300 composed of a charging control component 310 and a charging module 320, and the charging control component 310 is adapted to be connected to a power source. The charging module 320 includes a brush plate assembly 321 and a brush block assembly 322. One of the brush plate assembly 321 and the brush block assembly 322 is disposed on the guiding assembly 100 and is electrically connected to the charging control component 310, and the other of the brush plate assembly 321 and the brush block assembly 322 is disposed on the car assembly 200 and is connected to the battery module.

[0048] For example: the brush plate assembly 321 is disposed on the car assembly 200, and the brush block assembly 322 is disposed on the guiding assembly 100. When the brush plate assembly 321 moves up and down with the car assembly 200 and is paired and connected with the brush block assembly 322, the circuit of the brush block assembly 322 is turned on, and the battery module is charged through the cooperation of the brush block assembly 322 and the brush plate assembly 321, which is relatively convenient for charging; when the user needs to use the lifting device, at this time, whether the battery module is fully charged or not, the car assembly can be directly controlled to move up and down, so that the brush plate assembly 321 and the brush block assembly 322 are separated to interrupt charging, without additional operations, the charging process is simple, and the operation is more convenient.

[0049] Continue to refer to Figure 3 In some embodiments of the present utility model, the brush plate assembly 321 includes a brush plate base 3211, a first electrode sheet 3212, and a protective cover 3213. The brush plate base 3211 is fixedly connected to the car assembly 200 or the guiding assembly 100. The first electrode sheet 3212 is disposed on the brush plate base 3211. The protective cover 3213 is slidably engaged with the brush plate base 3211 and is used to cover the first electrode sheet 3212 to prevent the first electrode sheet 3212 from being exposed when not in use, so as to affect the sensitivity of the first electrode sheet 3212.

[0050] Continue to refer to Figure 4, in some embodiments of the present utility model, the brush block assembly 322 includes a brush block base 3221, a second electrode plate 3222, and a stopper 3223. The brush block base 3221 is fixedly connected to the car assembly 200 or the guiding assembly 100. The second electrode plate 3222 is fixedly connected to the brush block base 3221. The stopper 3223 is disposed above the brush block base 3221 and is used to lift the protective cover 3213 on the brush plate assembly 321 to ensure sufficient contact between the electrode plates on the brush plate assembly 321 and the brush block assembly 322.

[0051] Among them, the stopper 3223 can be an "L"-shaped sheet metal part. The stopper 3223 can be disposed on the brush block base 3221 or a protruding structure protruding outward from the brush block base 3221. When the brush block assembly 322 is disposed on the guiding assembly 100, the stopper 3223 can also be disposed on the guiding assembly 100, as long as it is ensured that the stopper 3223 is located above the brush block base 3221 and can lift the protective cover 3213 on the brush plate assembly 321. When the brush block assembly 322 is disposed on the car assembly 200, the stopper 3223 can also be disposed on the car assembly 200.

[0052] Among them, the length of either the first electrode plate 3212 or the second electrode plate 3222 is greater than the length of the other, so that the first electrode plate 3212 and the second electrode plate 3222 are continuously paired and connected, and further the brush block assembly 322 and the brush plate assembly 321 are kept paired and connected.

[0053] For example, when the brush plate assembly 321 is disposed on the car assembly 200 and the brush block assembly 322 is disposed on the guiding assembly 100, the length of the second electrode plate 3222 in the brush plate assembly 321 can be set to be greater than the length of the first electrode plate 3212 in the brush block assembly 322. When the brush plate assembly 321 moves up and down with the car assembly 200, before reaching the determined charging position, it can be ensured that the brush plate assembly 321 and the brush block assembly 322 are paired and connected. When the circuit of the brush block assembly 322 is connected, the brush block assembly 322 and the brush plate assembly 321 are paired and connected to charge the battery module, which can improve the reliability of the charging device 300.

[0054] It should be noted that when the brush plate assembly 321 is disposed on the car assembly 200 and the brush block assembly 322 is disposed on the guiding assembly 100, and the length of the second electrode plate 3222 in the brush plate assembly 321 is set to be greater than the length of the first electrode plate 3212 in the brush block assembly 322, the length of the second electrode plate 3222 can be set to be twice the length of the first electrode plate 3212, and the charging position is set to the position where the first electrode plate 3212 is located in the middle of the second electrode plate 3222. With such a setting, even if there is a slight position deviation when the car assembly 200 stops at the charging position, it will not affect the pairing and connection between the brush block assembly 322 and the brush plate assembly 321, and the reliability is relatively high.

[0055] Continue to refer to Figure 4 In some embodiments of the present utility model, the charging device 300 further includes a position detection component 330, and the position detection component 330 is disposed on either the guiding assembly 100 or the car assembly 200. When the car assembly 200 moves up and down along the guiding assembly 100 and the brush plate assembly 321 and the brush block assembly 322 are continuously paired and connected, the other of the guiding assembly 100 and the car assembly 200 triggers the position detection component 330 to act to charge the battery module.

[0056] For example, when the brush plate assembly 321 is disposed on the car assembly 200 and the brush block assembly 322 is disposed on the guiding assembly 100, the position detection component 330 is disposed on the guiding assembly 100. When the car assembly 200 moves up and down along the guiding assembly 100 and touches the position detection component 330, the position detection component 330 sends an action signal to trigger the charging device 300 to charge. When set like this, by controlling the charging or power-off of the charging device 300 through position feedback, the safety of the charging device 300 can be improved.

[0057] Continue to refer to Figure 1 and Figure 2 In some embodiments of the present utility model, the charging device 300 further includes a triggering component 340, and the triggering component 340 is disposed on the other of the guiding assembly 100 and the car assembly 200, and is adapted to trigger the position detection component 330 to act to charge the battery module.

[0058] For example, when the brush plate assembly 321 is disposed on the car assembly 200 and the brush block assembly 322 is disposed on the guiding assembly 100, the position detection component 330 is disposed on the guiding assembly 100, and the triggering component 340 is correspondingly disposed on the car assembly 200. When the car assembly 200 drives the triggering component 340 to move up and down along the guiding assembly 100 and touches the position detection component 330, the position detection component 330 sends an action signal to trigger the charging device 300 to charge.

[0059] Among them, the triggering component 340 can be a trigger plate or a block structure. The triggering component 340 is detachably connected to the outer side wall of the car assembly 200 through fasteners such as screws and bolts, and the triggering component 340 is located on the extension path of the position detection component 330 and can touch the position detection component 330 to make the position detection component 330 generate an action signal.

[0060] When the triggering component 340 is not provided, a convex structure can be provided on the side wall of the car assembly 200 to trigger the position detection component 330 to act through this convex structure.

[0061] Among them, the position detection component 330 includes a contact position sensor or a proximity position sensor. When the trigger component 340 touches the position sensor, the position sensor is converted into an output signal and fed back to the charging device 300. The charging device 300 is charged to realize the electrical linkage feedback function of the charging device 300, making the charging device 300 safer.

[0062] When the position sensor is a contact sensor, the contact sensor may include a travel switch, a two-dimensional matrix position sensor, etc. For example, the position detection component 330 is a travel switch, which is fixedly connected to the outer wall of the car assembly 200 by bolts, and when the trigger component 340 moves with the car assembly 200, the trigger component 340 touches the travel switch, and the contact inside the travel switch moves, thereby realizing the charging circuit conduction.

[0063] When the position sensor is a proximity sensor, the proximity sensor may include an electromagnetic type, a photoelectric type, a differential transformer type, an eddy current type, a capacitive type, a reed switch or a Hall type, etc. The proximity sensor does not need to contact the trigger component 340. When the trigger component 340 and the proximity sensor are close to a set distance, a switch sends an "action" signal, thereby realizing the conduction of the charging circuit.

[0064] Continue reading Figure 4 In some embodiments of the present invention, when the position detection component 330 is a contact position sensor, the contact position sensor is a limit switch.

[0065] At this time, the charging position where the brush block assembly 322 and the brush plate assembly 321 are paired and connected corresponds to the installation position of the limit switch. When the brush plate assembly 321 moves to the charging position with the car assembly 200, the brush plate assembly 321 and the brush block assembly 322 are paired and connected first, and the limit switch is triggered to charge the battery module, ensuring that the car assembly 200 is in place before charging; when the brush plate assembly 321 moves to the position away from the charging position with the car assembly 200, the limit switch is activated first to stop charging the battery module, and the brush plate assembly 321 and the brush block assembly 322 are completely separated to avoid arcing between the brush plate assembly 321 and the brush block assembly 322.

[0066] For example: when the brush plate assembly 321 is provided on the car assembly 200 and the brush block assembly 322 is provided on the guide assembly 100, the limit switch is provided on the guide assembly 100, and the trigger member 340 is correspondingly provided on the car assembly 200. Since the length of the second electrode plate 3222 in the brush plate assembly 321 is set to be greater than the length of the first electrode plate 3212 in the brush block assembly 322, when the brush plate assembly 321 moves up and down with the car assembly 200, and before reaching the determined charging position, the stopper 3223 can lift the protective cover 3213 on the brush plate assembly 321. At this time, the electrode plates on the brush plate assembly 321 and the brush block assembly 322 can be paired and connected.

[0067] At this time, the brush plate assembly 321 continues to move with the car assembly 200 until the brush plate assembly 321 reaches the charging position. Then, the brush block assembly 322 and the brush plate assembly 321 are paired and connected, that is, the trigger member 340 touches the limit switch, and the limit switch acts to conduct the charging circuit of the charging device 300 to charge the battery module, which can ensure that the car assembly 200 is in place first and then charged; when the battery module moves with the car assembly 200 away from the charging position, the trigger member 340 releases the touch on the limit switch, the limit switch acts first to stop charging the battery module, and then the brush plate assembly 321 and the brush block assembly 322 are completely separated, avoiding the arcing phenomenon between the brush plate assembly 321 and the brush block assembly 322.

[0068] It should be noted that the installation position of the limit switch needs to ensure that the car assembly 200 is in place first and then charged, that is, when the brush block assembly 322 and the brush plate assembly 321 are completely butted, the limit switch acts to conduct the charging circuit of the charging device 300 to charge the battery module; the installation position of the limit switch also needs to ensure that the car assembly 200 is powered off first and then separated. The trigger member 340 releases the touch on the limit switch, the limit switch acts first to stop charging the battery module, and then the brush plate assembly 321 and the brush block assembly 322 are completely separated.

[0069] Specifically, the installation position of the limit switch is set with reference to the position of the car assembly 200 at the lower limit. That is, during the installation process, first dock the car assembly 200 at the lower limit position, then correspondingly set the brush block assembly 322 and the brush plate assembly 321 on the car assembly 200 and the guide assembly 100, and then install the limit switch according to the position where the brush block assembly 322 and the brush plate assembly 321 are completely butted.

[0070] Continue to refer to Figures 1 to 4 In some embodiments of the present invention, the charging device 300 further includes a mounting bracket 350. The mounting bracket 350 is provided on the guide assembly 100, and one of the position detection member 330 and the trigger member 340 and one of the brush block assembly 322 and the brush plate assembly 321 are provided on the mounting bracket 350.

[0071] Among them, the mounting bracket 350 mainly plays a role in supporting and fixing. The mounting bracket 350 can be set according to the installation positions of the brush block assembly 322 or the brush plate assembly 321, as well as the position detection component 330 or the trigger component 340, to ensure that the brush block assembly 322 and the brush plate assembly 321 can be paired and connected, and the position detection component 330 and the trigger component 340 can touch each other.

[0072] For example, when the brush plate assembly 321 is arranged on the car assembly 200 and the brush block assembly 322 is arranged on the guiding assembly 100, the position detection component 330 is arranged on the guiding assembly 100, and the trigger component 340 is correspondingly arranged on the car assembly 200. First, the mounting bracket 350 is fixedly connected to the ladder of the guiding assembly 100 through fasteners such as bolts and screws, and then the brush block assembly 322 and the position detection component 330 are respectively fixed to the mounting bracket 350 through fasteners such as bolts and screws.

[0073] Figure 5 It is a system block diagram of the charging device 300 provided by the embodiment of the present utility model.

[0074] Refer to Figure 5 , in some embodiments of the present utility model, the charging control component 310 includes a charging box 311 and a charger. The charging box 311 includes a housing and a power switch 312, a contactor, and a transformer arranged inside the housing.

[0075] The contactor is electrically connected to an AC power supply of 220V or 230V through the power switch 312. The AC power supply can be a municipal power supply unit or a power generation device. The contactor starts and stops the charging operation by controlling the opening and closing of the charging circuit. The contactor can also be used to protect the charging circuit from faults such as overload, short circuit, and earthquake. When the load of the charging circuit is too large or a short circuit occurs, the contactor will automatically disconnect the circuit to prevent damage to the charging circuit and other devices. The auxiliary contacts of the contactor can be used to transmit signals, such as status indicator lights, alarm devices, etc.

[0076] The limit switch is electrically connected to the contactor. When the limit switch is triggered, the charging circuit is closed to charge the battery module, ensuring that the car assembly 200 is in place first before charging. Equivalently, the limit switch is connected to the charging circuit to control the start or stop of the charging circuit.

[0077] The transformer is electrically connected to an AC power supply of 220V or 230V through the power switch 312. The transformer is used for voltage conversion to convert the voltage of the power supply into the voltage required for the coil and indicator light of the contactor.

[0078] The charger is electrically connected to the contactor, and the charger is also electrically connected to the brush plate assembly 321 or the brush block assembly 322. The charger is used to convert alternating current into direct current required by the battery. The charger is also used to protect the charger and the battery module from the effects of overcharging, over-discharging, overheating, etc. of the battery.

[0079] Equivalently, in the charging device 300 provided by the embodiment of the present invention, the contactor has three triggering mechanisms, that is, when the power switch is in the open state, the limit switch is in the triggered state, and the coil of the contactor is in the energized state, the contactor starts the charging operation by controlling the opening of the charging circuit. For the three triggering mechanisms of the contactor, if any one of them is missing, the charging circuit stops charging to improve the safety of the charging circuit.

[0080] Figure 6 It is the charging circuit diagram of the charging device 300 provided by the embodiment of the present invention.

[0081] Refer to Figure 6 , a power indicator light 313 and a charging indicator light 314 are further provided on the charging box 311. The power indicator light 313 is arranged on the circuit between the power switch and the input end of the transformer T. When the power indicator light 313 is on, it is used to prompt the user that the power is connected. The charging indicator light 314 is arranged on the circuit where the output end of the transformer T is located. When the charging indicator light 314 is on, it is used to prompt the user that the charging device 300 is in the charging state.

[0082] Continue to refer to Figure 6 , the three-phase plug CT of the power switch QS0 is connected to the socket of the municipal power supply unit. The charger is electrically connected to the contactor, and the charger is also electrically connected to the brush plate assembly 321 or the brush block assembly 322.

[0083] When the plug CT is connected to an AC power supply of 220V or 230V, the power switch QS0 is turned on. One path passes through the transformer T, making the input end and the output end of the transformer T charged. The transformer T converts the 230V AC power into the 24V voltage required by the power indicator light 313. At this time, the power indicator light 313 is on. The other path is connected to the normally open contact KM0 of the contactor.

[0084] When the limit switch SQ15 is triggered by the descending car assembly 200 or the triggering component 340 provided on the car assembly 200, the coil of the contactor is energized, and the contact KM0 of the contactor is attracted. The charger BC powers on and outputs direct current to the brush block assembly 322 or the brush plate assembly 321. The brush plate assembly 321 on the car assembly 200 is paired and connected with the brush block assembly 322 to realize automatic charging of the battery module, or the brush block assembly 322 on the car assembly 200 is paired and connected with the brush plate assembly 321 to realize automatic charging of the battery module. At this time, the charging indicator light 314 is on.

[0085] When the lifting equipment provided by the embodiment of the utility model is automatically charged, the car assembly 200 descends to the starting platform, which can be understood as the platform located at the bottommost layer of the tower barrel. The guiding assembly 100 is provided with a limiting device near the starting platform. When the car assembly 200 is located at the position where the limiting device is located, it can be set that the brush plate assembly 321 and the brush block assembly 322 are paired and connected for automatic charging. That is, the position where the car assembly 200 is located at the limiting device can be recorded as the charging position.

[0086] When in the charging position, the triggering component 340 located on the car assembly 200 touches the limit switch, and the limit switch acts to conduct the charging circuit of the charging device 300. After a delay of 5 s, the brush block assembly 322 and the brush plate assembly 321 are paired and connected to charge the battery module. When the battery module of the car assembly 200 is fully charged, the charging device 300 can automatically stop charging to ensure that the battery module is not overcharged. However, as long as the car assembly 200 stays on the starting platform and the power of the battery module is consumed to be lower than the threshold of 80%, the charging device 300 automatically charges the battery module again to ensure that the battery module is in a fully charged state, which is more convenient to operate.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
