[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Combine the following Figures 1 to 9 The battery hanger of the present invention is described.

[0055] like Figures 1 to 9 As shown, an embodiment of the present invention provides a battery hanger, including a hanger arm 10, a hanger 20, a lifting device 30, a limit device 40, and a locking mechanism 50. Specifically, as Figure 1 As shown, the sling arm 10 may use existing common devices, for example, it may include a boom crossbeam 101 and a boom trolley 102. The boom crossbeam 101 is installed on the upper end of the boom trolley 102 and can be used to install the sling 20. The boom trolley 102 may use an existing rail guided vehicle (RGV) to perform linear reciprocating motion on the walking platform 90. The walking platform 90 can be rotatably connected to the slewing platform 100 through a slewing bearing to transport the battery 80. The sling 20 may use existing common devices to grab and unload the battery 80. The sling 20 is connected to the sling arm 10 through a lifting device 30, and the lifting device 30 is used to drive the sling 20 to perform lifting and lowering motion along the height direction of the sling arm 10. The lifting device 30 may use existing common devices, for example, a winch may be used, and the winch is connected to the sling 20 through a flexible member such as a wire rope 301, and drives the sling 20 to move up and down. However, in the related art, the sling 20 may shake during movement, thereby affecting the battery replacement operation and even causing safety accidents.

[0056] Therefore, further, the limit device 40 is arranged on the spreader arm 10 to prevent the spreader 20 from shaking relative to the spreader arm 10. In this way, the limit device 40 and the spreader 20 are arranged independently, which facilitates the subsequent switching between the anti-shake state and the flexible state. The locking mechanism 50 is used to lock and unlock the spreader 20 and the limit device 40, and can switch between the locked state and the unlocked state. Figure 2 As shown, when the locking mechanism 50 is in the locked state, the sling 20 and the limiter 40 remain relatively immobile, so that the sling 20 and the limiter 40 are combined together, the swinging movement of the sling 20 is restricted, and the sling 20 does not shake during the lifting and horizontal movements, and maintains an anti-shake state. Fig. 9As shown, when the locking mechanism 50 is in the unlocked state, the sling 20 and the limiting device 40 can generate relative movement, so that the sling 20 and the limiting device 40 are separated, and the sling 20 can move freely without restraint. When taking and placing the battery 80, the sling 20 has a flexible state and can swing within a certain range, so that the sling 20 can position the battery 80 through guidance. In other words, the limiting device 40 and the sling 20 are two independent structures. During operation, by utilizing the locking mechanism 50, the limiting device 40 and the sling 20 can be separated and combined to realize the switching of the anti-shake state and the flexible state of the sling 20, so that the battery sling can meet different usage requirements. It should be noted that, as shown in the example Figure 1 For the placement position of the battery hanger shown in the figure, the up and down directions in the figure are the up and down positions, and the height direction of the hanger arm 10.

[0057] With such a configuration, when the battery 80 is hoisted, the sling 20 and the limit device 40 can be locked by the locking mechanism 50, so that the sling 20 remains stationary relative to the limit device 40, thereby preventing the sling 20 from shaking and realizing the anti-shake function of the sling 20. When the battery 80 is taken or placed, the sling 20 and the limit device 40 can be unlocked by the locking mechanism 50, so that the sling 20 and the limit device 40 can produce relative movement, thereby releasing the sling 20, and realizing the flexible taking and placing of the battery 80 by the sling 20. The device is easy to operate and has high safety in use, and solves the problem in the prior art that the battery sling has a large shaking amount and is inconvenient to operate due to the excessive expansion and contraction of the hoisting wire rope.

[0058] In the embodiment of the present invention, the limiting device 40 includes a limiting seat 401 and a guiding mechanism. The limiting seat 401 is used to prevent the sling 20 from shaking relative to the sling arm 10, and the guiding mechanism is used to guide the movement of the limiting seat 401. Specifically, Figure 1 As shown, the limit seat 401 is slidably connected to the spreader arm 10 and moves along the height direction of the spreader arm 10. Correspondingly, the guide mechanism is arranged along the height direction of the spreader arm 10. In this arrangement, the limit seat 401 slides up and down, so that when the spreader 20 moves up and down, the limit seat 401 can follow the movement, thereby ensuring that the spreader 20 will not shake relative to the spreader arm 10, and maintain the anti-shake function when in the lifting state. In addition, the limit seat 401 is guided to move by the guide mechanism, so that the limit seat 401 runs along a certain track, and the movement is more stable and reliable, which helps to improve the anti-shake performance of the spreader 20.

[0059] In an optional embodiment of the present invention, the locking mechanism 50 includes a matching locking pin 501 and a pin hole 502, and one of the limiting seat 401 and the sling 20 is provided with a locking pin 501, and the other is provided with a pin hole 502. When the locking pin 501 is inserted into the pin hole 502, the sling 20 and the limiting device 40 are in a locked state. When the locking pin 501 is disengaged from the pin hole 502, the sling 20 and the limiting device 40 are in an unlocked state. In other words, the locking pin 501 can be provided on the limiting seat 401, and the pin hole 502 can be provided on the sling 20. Alternatively, the locking pin 501 can be provided on the sling 20, and the pin hole 502 can be provided on the limiting seat 401.

[0060] by Figure 4 and Figure 5 As shown in the example, the limit seat 401 is provided with a locking pin 501, and the lifting device 20 is provided with a pin hole 502 that matches the locking pin 501. Figure 3 As shown, when the locking pin 501 is inserted into the pin hole 502, the sling 20 and the limit device 40 are in a locked state. At this time, the sling 20 cannot shake and maintains an anti-shake posture in the lifting state. Figure 8 As shown, when the locking pin 501 is out of the pin hole 502, the sling 20 and the limiting device 40 are in an unlocked state. At this time, the sling 20 is no longer constrained by the limiting seat 401, and has a flexible posture when taking and placing the battery 80, which is convenient for aligning the battery 80.

[0061] In this way, the anti-shake posture and the flexible posture are switched through the mutual cooperation of the locking pin 501 and the pin hole 502, which meets the use requirements of the battery hanger under different working conditions and is more convenient and reliable to operate. Of course, the locking mechanism 50 is not limited to the above-mentioned matching form of the pin shaft and the hole, and other forms of components such as wedge-shaped locking blocks and triangular locking blocks can also be used, and adaptive adjustments can be made to achieve the switching of the two postures of the above-mentioned hanger 20 by inserting or withdrawing from the locking hole.

[0062] In a specific embodiment of the present invention, the guide mechanism includes a guide wheel 402 and a guide rail 403. Figure 4 As shown, the guide wheel 402 can be rotatably connected to the limit seat 401 via a rotating shaft. Figure 3 As shown, the guide rail 403 is arranged on the spreader arm 10, and the guide rail 403 is arranged along the height direction of the spreader arm 10. The guide rail 403 is provided with a guide groove 4031 adapted to the guide wheel 402, and the guide wheel 402 rolls in the guide groove 4031. With such an arrangement, the guiding effect on the limit seat 401 is achieved through the mutual cooperation of the roller and the slide rail, and the structure is simple and easy to implement. In addition, the use of rollers can also reduce the friction during the lifting process, making the movement smoother. It should be noted that, with the above Figure 3 For the placement position of the battery hanger shown in the figure, the up and down direction in the figure is the height direction of the hanger arm 10.

[0063] In order to better guide the Figure 3 As shown, guide rails 403 are symmetrically arranged on both sides of the limit seat 401. Figure 4 As shown, guide wheels 402 are correspondingly arranged on both sides of the limiting seat 401, and the guide wheels 402 move in the guide grooves 4031. At least two guide wheels 402 can be arranged on one side of the limiting seat 401, and each guide wheel 402 is spaced apart and distributed along the height direction of the limiting seat 401. Specifically, as Figure 4 As shown, the limit seat 401 includes a first seat body 4011 and a second seat body 4012 connected to each other. The first seat body 4011 is arranged along the height direction of the limit seat 401, and the second seat body 4012 is perpendicular to the first seat body 4011. The guide wheel 402 is rotatably arranged on both sides of the first seat body 4011, for example, it can be connected by a rotating shaft. The locking pin 501 is fixedly arranged on the second seat body 4012, for example, it can be connected by a connecting plate 503, wherein the connecting plate 503 and the second seat body 4012 can be connected by welding or bolts. It should be noted that, as shown in FIG. Figure 4 For the placement of the battery hanger shown in the figure, the up and down direction in the figure is the height direction of the limit seat 401. Of course, the guide mechanism is not limited to the above-mentioned roller and slide rail cooperation form, and can also use sliders and guide rails, multi-stage telescopic guide rails, etc., and make adaptive adjustments to achieve the guiding effect on the limit seat 401.

[0064] Furthermore, in the embodiment of the present invention, the battery hanger further includes a stopper 60, which is disposed on the hanger arm 10. The stopper 60 abuts against the limit seat 401 to prevent the limit seat 401 from further descending. For example, the stopper 60 can be configured as a support plate. Specifically, Figure 3 As shown, the first seat body 4011 has a cavity inside to reduce the weight of the battery hanger. In actual application, the upper end of the first seat body 4011 abuts against the stopper 60, so that the limit seat 401 does not fall. The lower end of the first seat body 4011 is provided with a groove for the stopper 60 to pass through, so as to ensure that the limit seat 401 can rise together with the hanger 20. It should be noted that Figure 3 For the placement of the battery hanger shown in the figure, the up and down directions in the figure are the upper and lower directions.

[0065] like Figure 8 As shown in FIG. 1 , when the lifting device 20 is in the downward movement, when the limit seat 401 contacts the stopper 60, the limit seat 401 stops descending. At this time, if the lifting device 20 continues to descend, the locking pin 501 will be disengaged from the pin hole 502, unlocking the lifting device 20 and the limit seat 401, releasing the lifting device 20, and facilitating the lifting device 20 to flexibly take and place the battery 80. Figure 3 As shown, the locking pin 501 will be inserted into the pin hole 502 again to lock the sling 20 and the limit seat 401. Figure 6 and Figure 7 As shown, if the sling 20 continues to move upward, the sling 20 will drive the limiting seat 401 to separate from the blocking member 60, so that the limiting device 40 can rise together with the sling 20.

[0066] In this arrangement, the stopper 60 supports the limit seat 401, determines the lowest position of the limit device 40, and can also realize the switching between the locked state and the unlocked state of the locking mechanism 50. On the one hand, it is convenient for the sling 20 to flexibly take and place the battery 80, and on the other hand, when the wire rope 301 is retracted, the limit device 40 can rise with the sling 20, reducing the requirements for the movement synchronization of the limit device 40.

[0067] In an optional embodiment of the present invention, the battery hoist further includes a height adjustment device 70, which is disposed on the hoist arm 10. The height adjustment device 70 is used to adjust the height position of the stopper 60, thereby changing the lowest position of the limit device 40, and further adjusting the height position of the locked state and the unlocked state to adapt to the flexible lifting and anti-shake function of batteries 80 of different models and specifications.

[0068] Specifically, in the embodiment of the present invention, the height adjustment device 70 includes a driving sprocket 701, a driven sprocket 702, a chain 703, and a driving member 704. Figure 3 As shown, the driving sprocket 701 and the driven sprocket 702 are both rotatably connected to the spreader arm 10, and can be installed on the spreader arm 10 through a sprocket fixing plate 705. The driving sprocket 701 and the driven sprocket 702 are spaced apart along the height direction of the spreader arm 10, and the chain 703 is meshed with the driving sprocket 701 and the driven sprocket 702, and the chain 703 is connected to the stopper 60. The driving member 704 is used to drive the driving sprocket 701 to rotate, and the driving member 704 can be a motor or a motor. Taking the motor as an example, the motor drives the driving sprocket 701 to rotate, which will drive the chain 703 and the driven sprocket 702 to rotate. The chain 703 will drive the stopper 60 to move up and down, thereby adjusting the height position of the stopper 60 to meet the application requirements of different models and different batteries. Of course, the height adjustment device 70 is not limited to the above-mentioned sprocket and chain driving method, and can also use ball screw, oil cylinder, air cylinder, electric cylinder and other driving methods, and make adaptive adjustments to drive the baffle 60 to move up and down, thereby achieving the purpose of adjusting the height position of the baffle 60.

[0069] As an optional embodiment of the present invention, Figure 4 As shown, the locking pin 501 is provided with a tapered guide portion 5011. This arrangement facilitates the insertion of the locking pin 501 into the pin hole 502, improves the switching efficiency of the locking mechanism 50, and thus improves the battery replacement efficiency. Among them, the tapered guide portion 5011 and the locking pin 501 can be connected by welding or threading. The locking pin 501 can also be set as a hollow structure to reduce the weight of the battery hanger.

[0070] Further, in an embodiment of the present invention, if Figure 4 As shown, there are at least two locking pins 501, and each locking pin 501 is spaced apart along the width direction of the hanger arm 10, and the pin holes 502 are arranged one by one with the locking pins 501. Figure 4 For the placement of the battery hanger shown in the figure, the left and right direction in the figure is the width direction of the hanger arm 10. Such an arrangement can improve the stability of the switching action of the locking mechanism 50 and make it more reliable to use.

[0071] In an optional embodiment of the present invention, Figure 4 As shown, the lock pin 501 is provided with a limiting step surface 5012, and the limiting step surface 5012 is clamped on the sling 20 to prevent the limiting seat 401 from continuing to fall. In this way, when the limiting step surface 5012 is clamped on the upper surface of the sling 20, the limiting seat 401 will no longer fall, thereby playing a limiting role, facilitating the coordinated use of the pin hole and improving the battery replacement efficiency.

[0072] In summary, an embodiment of the present invention provides a battery hoist, which specifically includes a hoist arm 10, a hoist 20, a lifting device 30, a limit device 40, a locking mechanism 50, a stopper 60, and a height adjustment device 70. Among them, the limit device 40 is slidably arranged on the hoist arm 10, and is independently arranged relative to the hoist 20. The two can be separated to form two independent structures. The locking mechanism 50 utilizes the mutual cooperation of the locking pin 501 and the pin hole 502 to achieve the switching between the unlocking state and the locking state, thereby realizing the separation and combination of the limit device 40 and the hoist 20, and further realizing that the hoist 20 has a flexible posture when taking and placing the battery 80, and has an anti-shake posture in other working states.

[0073] Furthermore, the limit device 40 is supported by the stopper 60 to limit the lowest position that the limit device 40 can reach, and the stopper 60 is used to complete the switching action between the unlocked state and the locked state. At the same time, the height adjustment device 70 can also control the height position of the stopper 60, realizing the flexible lifting and anti-shake function of batteries 80 of different models and specifications.

[0074] Therefore, when hoisting the battery 80, the sling 20 and the limit device 40 can be locked by the locking mechanism 50, so that the sling 20 remains stationary relative to the limit device 40, thereby preventing the sling 20 from shaking and realizing the anti-shake function of the sling 20. When taking and placing the battery 80, the sling 20 and the limit device 40 can be unlocked by the locking mechanism 50, so that the sling 20 and the limit device 40 can produce relative movement, thereby releasing the sling 20, and realizing the flexible taking and placing of the battery 80 by the sling 20. The device is easy to operate, easy to implement, and highly safe to use, and solves the problem in the prior art that the battery sling has a large shaking amount and is inconvenient to operate due to the excessive expansion and contraction of the hoisting wire rope.

[0075] The battery swap station provided by the present invention is described below. The battery swap station described below and the battery hanger described above can be referenced to each other.

[0076] The embodiment of the present invention also provides a battery swap station, including the battery hoist in each of the above embodiments. In this way, when hoisting the battery 80, the hoist 20 and the limit device 40 can be locked by the locking mechanism 50, so that the hoist 20 remains motionless relative to the limit device 40, thereby preventing the hoist 20 from shaking and realizing the anti-shake function of the hoist 20. When taking and placing the battery 80, the hoist 20 and the limit device 40 can be unlocked by the locking mechanism 50, so that the hoist 20 and the limit device 40 can produce relative movement, thereby releasing the hoist 20, and realizing the flexible taking and placing of the battery 80 by the hoist 20. The device is easy to operate and has high safety in use. It solves the problem in the prior art that the battery hoist has a large amount of shaking and is inconvenient to operate due to the excessive scaling of the hoisting wire rope. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned battery hoist, so it will not be repeated here.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
