Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present application and the features of different embodiments or examples without contradiction.

[0062] The embodiments of the present application will be described below. Figures 1 to 17 It should be understood that the following description is only a schematic embodiment of the present application and does not constitute any limitation on the present application.

[0063] Referring to Figures 1 to 17 The embodiment of the present application provides a lifting device applied to a building or equipment ladder, which can run up and down along a guide member mounted on the building or equipment ladder to transport personnel and materials in a high-altitude working environment.

[0064] As Figures 1 to 3 shown, the lifting device includes a lifting vehicle body 100 and a battery assembly 500, and the lifting vehicle body 100 serves as a load-bearing main body of the lifting device, and an installation portion 101 is provided on the lifting vehicle body 100.

[0065] The battery assembly 500 comprises a battery compartment 501 and a battery component 502, the battery compartment 501 is mounted to the mounting portion 101, and the battery component 502 is mounted in the battery compartment 501 and used to supply power to the PCB board in the lifting device. A clamping component 5022 is arranged on any one of the battery compartment 501 and the battery component 502, and a matching component 5012 for clamping is arranged on the other one of the battery compartment 501 and the battery component 502.

[0066] Specifically, the clamping component 5022 comprises a clamping body 5022-1 arranged on the battery component 502, the clamping body 5022-1 is provided with a clamping portion 5022-3 penetrating through the battery component 502 and extending outside the battery component 502. The matching component 5012 can be a matching portion matched with the clamping portion 5022-3, and the matching portion can be a clamping groove.

[0067] When the battery component 502 is mounted in the battery compartment 501, the clamping portion 5022-3 can be matched with the matching portion to achieve the clamping connection. In the mounting process, no additional mounting tool is needed, the operation is convenient, and the assembly is fast; and only a simple insertion action is needed in the assembly process, without rotation or positioning work, so that the mounting process of the battery component 502 on the battery compartment 501 can be simplified, and the assembly efficiency of the battery assembly 500 can be improved.

[0068] It should be noted that the arrangement form of the clamping portion 5022-3 is not limited, and the clamping portion 5022-3 can be a straight arm buckle, an “L” shaped buckle, a “U” shaped buckle or a circumferential buckle. When selecting the clamping portion 5022-3, a straight arm type buckle can be selected for convenient processing; an “L” shaped buckle, a “U” shaped buckle or a circumferential buckle can be selected to increase the structural strength of the clamping portion 5022-3, and the “L” shaped buckle and the “U” shaped buckle have greater elasticity due to the increase of the effective length. In addition, in order to make the installation of the clamping portion 5022-3 more firm, the clamping portion 5022-3 can be integrally formed with the clamping body 5022-1.

[0069] As shown in Figures 4 to 14 some embodiments of the present application, the clamping component 5022 further comprises a second elastic member 5022-7; the clamping body 5022-1 is further provided with an adapter portion 5022-2, and the clamping body 5022-1 is rotationally connected to the battery component 502 through the adapter portion 5022-2, and the second elastic member 5022-7 can be located between the battery component 502 and the clamping portion 5022-3.

[0070] Of course, the second elastic member 5022-7 can also be located between the battery component 502 and the adapter portion 5022-2, or the second elastic member 5022-7 is located between the battery component 502 and the clamping portion 5022-3 and the adapter portion 5022-2 at the same time. The second elastic member 5022-7 can be a spring or other component capable of elastic deformation.

[0071] When the clamping portion 5022-3 is clamped in the card slot, the elastic restoring force of the second elastic member 5022-7 can push the clamping portion 5022-3 to remain in the card slot, ensuring that the clamping portion 5022-3 cooperates reliably with the card slot.

[0072] When it is necessary to release the cooperation between the clamping portion 5022-3 and the card slot, it is only necessary to press the adapter portion 5022-2 or the clamping portion 5022-3 to overcome the elastic force of the second elastic member 5022-7, so that the clamping portion 5022-3 is separated from the card slot, and the battery component 502 is disassembled from the battery compartment 501. The disassembly process is more convenient, time-saving and labor-saving.

[0073] In order to facilitate the pressing of the adapter portion 5022-2, the adapter portion 5022-2 and the clamping portion 5022-3 are arranged separately, the clamping portion 5022-3 cooperates with the card slot on the battery compartment 501, and the adapter portion 5022-2 is arranged higher than the battery compartment 501. By pressing the adapter portion 5022-2, the clamping portion 5022-3 is separated from the card slot, and the battery component 502 is disassembled from the battery compartment 501.

[0074] In addition, mounting holes 5022-5 are formed on opposite sides of the adapter portion 5022-2, and a pin shaft is arranged in the mounting hole 5022-5 to rotate the clamping body 5022-1 through the pin shaft and connect the clamping body 5022-1 between the first housing 5024-1 and the second housing 5024-2.

[0075] A positioning hole 5022-4 is formed on the back of the clamping portion 5022-3, and a positioning boss 5024-8 corresponding to the position of the positioning hole 5022-4 is arranged on the cavity wall outside of the receiving cavity 5024-6 on the mounting housing 5024. One end of the second elastic member 5022-7 is embedded in the positioning hole 5022-4, and the other end of the second elastic member 5022-7 is embedded on the positioning boss 5024-8, so that both ends of the second elastic member 5022-7 can be positioned.

[0076] In addition, sealing flanges 5022-6 are arranged at the positions where the clamping body 5022-1 and the battery component 502 contact each other. Specifically, the sealing flanges 5022-6 are arranged at the positions where the clamping body 5022-1 and the mounting housing 5024 contact each other, so as to prevent gaps at the positions where the clamping body 5022-1 and the mounting housing 5024 contact each other, which affects the sealing of the inside of the battery component 502.

[0077] As shown in Figures 4 to 14 some embodiments of the present application, inside the first shell 5024-1 and the second shell 5024-2, and on both sides of the two cavity walls of the accommodating cavity 5024-6, installation grooves (not numbered in the figure) corresponding to the structure of the clamping component 5022 are arranged, and the clamping component 5022 is embedded in the installation grooves.

[0078] As shown in Figures 4 to 6 some embodiments of the present application, the first electrical connection part 5011 is arranged on the battery compartment 501, and the second electrical connection part 5021 corresponding to the position of the first electrical connection part 5011 is arranged on the battery component 502. When the battery component 502 is located in the battery compartment 501, the second electrical connection part 5021 abuts against the first electrical connection part 5011, so that the electrical connection between the battery component 502 and the battery compartment 501 is realized.

[0079] It can be understood that, by arranging the first electrical connection part 5011 on the battery compartment 501 and the second electrical connection part 5021 on the battery component 502, when the battery component 502 is located in the battery compartment 501, the second electrical connection part 5021 abuts against the first electrical connection part 5011, so that the electrical connection between the battery component 502 and the battery compartment 501 is realized, that is, the cable connection between the battery component 502 and the battery compartment 501 is avoided, and further, the running accidents of the lifting equipment caused by the brittleness, aging and fracture of the cable are avoided, and the safety of the running of the lifting equipment is further improved.

[0080] As shown in Figure 5 and Figure 6 some embodiments of the present application, the first electrical connection part 5011 includes a first conductor 5011-1 and a first mounting seat 5011-2. The first mounting seat 5011-2 is fixed on the outer side surface of the battery compartment 501, and the first conductor 5011-1 is fixed on the first mounting seat 5011-2. One end of the first conductor 5011-1 extends into the interior of the battery compartment 501 and can abut against the second electrical connection part 5021. The other end of the first conductor 5011-1 is electrically connected with the PCB in the lifting equipment.

[0081] Specifically, as shown in Figure 6 , the first conductor 5011-1 can be an electrode spring, that is, a component made of a metal conductor and having a certain deformation amount. Under the extrusion action of the second electrical connection part 5021, the first conductor 5011-1 can be slightly deformed to provide a reaction force to the second electrical connection part 5021, so that the first conductor 5011-1 and the second electrical connection part 5021 are in contact and the electrical connection is realized.

[0082] Further, the first conductor 5011-1 has a trigger segment, a fixing segment and a connecting segment connected in sequence, the fixing segment and the connecting segment are horizontal segments, and the fixing segment is fixed on the injection-molded first mounting seat 5011-2. The trigger segment can be in the form of a circular arc or a spring sheet, and when the trigger segment abuts against the second electrical connection part 5021, the trigger segment can be elastically deformed to ensure reliable electrical connection between the trigger segment and the second electrical connection part 5021.

[0083] As shown in Figure 5 and Figure 6 in some embodiments of the present application, on the basis of the above-mentioned embodiments, different from the above-mentioned embodiments, the first electrical connection part 5011 further includes a pressing plate 5011-3 and a first elastic member 5011-4, the pressing plate 5011-3 can be fixed on the outer side surface of the battery compartment 501 by using fasteners such as screws and bolts, the first mounting seat 5011-2 is rotationally connected to the pressing plate 5011-3 by using a hinge, and the first elastic member 5011-4 is located between the pressing plate 5011-3 and the first mounting seat 5011-2.

[0084] When the battery component 502 is installed into the battery compartment 501, the second electrical connection part 5021 abuts against the first conductor 5011-1, the first conductor 5011-1 is subjected to extrusion, the first mounting seat 5011-2 is forced to rotate around the hinge, and the first elastic member 5011-4 is extruded to be elastically deformed, that is, the first elastic member 5011-4 has the ability to restore the deformation. When the battery component 502 is separated from the battery compartment 501, the extrusion of the second electrical connection part 5021 on the first conductor 5011-1 is released, and the first elastic member 5011-4 restores the elastic deformation to drive the first mounting seat 5011-2 and the first conductor 5011-1 to reset.

[0085] When the second electrical connection part 5021 abuts against the first conductor 5011-1, the first elastic member 5011-4 in the compressed state pushes the first mounting seat 5011-2 to reversely extrude the second electrical connection part 5021 by the elastic restoring force when the first conductor 5011-1 is subjected to extrusion, which ensures more reliable electrical connection between the second electrical connection part 5021 and the first conductor 5011-1, avoids failure of the first conductor 5011-1 due to repeated extrusion, and affects the electrical connection between the first conductor 5011-1 and the second electrical connection part 5021.

[0086] As shown in Figure 10 and Figure 11As shown in the drawings, in some embodiments of the present application, the second electrical connection part 5021 comprises a second conductor 5021-1 and a second mounting seat 5021-2, the second mounting seat 5021-2 is fixed on the inner wall of the battery component 502 by a fastener such as a screw or a bolt; the second conductor 5021-1 is fixed on the injection-molded second mounting seat 5021-2, and the second conductor 5021-1 penetrates the side wall of the battery component 502 and abuts against the first conductor 5011-1.

[0087] It should be noted that the first mounting seat 5011-2 and the second mounting seat 5021-2 are both made of insulating material to prevent the first conductor 5011-1 from being in conduction with the battery compartment 501, and to prevent the second conductor 5021-1 from being in conduction with the shell of the battery component 502.

[0088] As shown in the drawings, Figures 7 to 13 In some embodiments of the present application, the battery component 502 comprises a battery body 5023 and a mounting shell 5024, the mounting shell 5024 is internally structured with a receiving cavity 5024-6, and the battery body 5023 is arranged in the receiving cavity 5024-6.

[0089] As shown in the drawings, Figure 2 , Figure 7 and Figure 8 A notch (not labeled in the drawings) is provided on the side wall of the mounting shell 5024, and the second conductor 5021-1 is arranged at the notch of the mounting shell 5024 through the second mounting seat 5021-2 to be exposed to the outside of the mounting shell 5024.

[0090] Specifically, the second conductor 5021-1 can be an electrode sheet having a connecting end and a contact end, the connecting end of the second conductor 5021-1 is located inside the mounting shell 5024 and is electrically connected with the battery body 5023; the contact end of the second conductor 5021-1 is embedded at the notch of the mounting shell 5024 for abutting against the first conductor 5011-1. The second conductor 5021-1 is provided in two groups, and the two groups of second conductors 5021-1 are respectively connected to the positive and negative electrodes of the battery body 5023.

[0091] In addition, the mounting shell 5024 is further provided with a power interface 5024-3 and a panel 5024-4. The power interface 5024-3 can be a DC power interface, through which the battery body 5023 is charged. The panel 5024-4 can be provided with a power button, a power switch indicator light, and a power display light. The power button can be used to control the on-off of the battery component 502, the power display light can be used to observe the battery power, and the power switch indicator light can be used to observe whether the power switch is turned on. The panel 5024-4 is connected with a PCB circuit board in the battery component 502. The PCB circuit board can be arranged between the battery body 5023 and the mounting shell 5024, corresponding to the position of the panel 5024-4.

[0092] The mounting shell 5024 is further provided with a waterproof film to prevent liquid or solid particles from entering the vicinity of the battery body 5023 and polluting the containing cavity 5024-6 of the mounting shell 5024, causing short circuit of electronic components, etc.

[0093] That is, the mounting shell 5024 wraps the battery body 5023 to prevent impurities from entering the inside of the mounting cavity of the battery body 5023, and to avoid damage to the battery body 5023 caused by collision.

[0094] As shown in FIG. 5, Figures 7 to 13 In some embodiments of the present application, the mounting shell 5024 includes a first shell 5024-1 and a second shell 5024-2, which are detachably connected. The battery body 5023 is installed in the containing space jointly limited by the first shell 5024-1 and the second shell 5024-2, that is, the containing cavity 5024-6 capable of containing the battery body 5023 is arranged in the first shell 5024-1 and the second shell 5024-2 respectively, and the structure shape of the containing cavity 5024-6 inside the first shell 5024-1 and the second shell 5024-2 corresponds.

[0095] Further, as shown in FIG. 5, Figure 9 and Figure 13 In order to improve the sealing between the first shell 5024-1 and the second shell 5024-2, and further improve the sealing in the mounting space of the battery body 5023, a sealing groove 5024-7 is arranged on any one of the first shell 5024-1 and the second shell 5024-2, and a sealing protrusion 5024-9 matched with the sealing groove 5024-7 is arranged on the other one of the first shell 5024-1 and the second shell 5024-2.

[0096] For example, the first shell 5024-1 is provided with a sealing groove 5024-7 at the edge of the accommodating cavity 5024-6, and the second shell 5024-2 is provided with a sealing protrusion 5024-9 at the edge of the accommodating cavity 5024-6, when the first shell 5024-1 and the second shell 5024-2 are combined, the sealing protrusion 5024-9 is buckled in the sealing groove 5024-7 to realize the sealing between the first shell 5024-1 and the second shell 5024-2.

[0097] That is, the first shell 5024-1 is provided with a groove along the cavity wall of the accommodating cavity 5024-6 to form a sealing groove 5024-7, and the second shell 5024-2 is provided with a sealing protrusion 5024-9 extending outward from the end face of the second shell 5024-2 along the cavity wall of the accommodating cavity 5024-6, by the cooperation of the sealing protrusion 5024-9 and the sealing groove 5024-7, the first shell 5024-1 and the second shell 5024-2 are combined and sealed to seal the battery body 5023 in the inside of the mounting shell 5024.

[0098] Further, at least one of the sealing protrusion 5024-9 and the sealing groove 5024-7 can be provided with a sealing ring, and the sealing between the first shell 5024-1 and the second shell 5024-2 is further improved.

[0099] In addition, the first shell 5024-1 and the second shell 5024-2 can be fixed by using countersunk bolts, that is, countersunk holes are formed on the four corners of the first shell 5024-1, and threaded holes corresponding to the positions of the countersunk holes are formed on the second shell 5024-2. During installation, the positioning can be realized by the cooperation of the sealing protrusion 5024-9 and the sealing groove 5024-7, and then the first shell 5024-1 and the second shell 5024-2 are fixed by the countersunk bolts to form an integral structure.

[0100] In addition, the connection between the first shell 5024-1 and the second shell 5024-2 can also be connected in the form of hinge.

[0101] As shown in Figures 1 to 3 , and Figure 15 and Figure 16 As shown in some embodiments of the present application, on the basis of the above-mentioned embodiments, the difference from the above-mentioned embodiments is that the lifting device further comprises a locking mechanism 200, which is arranged in the lifting vehicle body 100 to selectively lock the lifting vehicle body 100 to the guide member.

[0102] As shown in Figure 15 , and Figure 16As shown, the locking mechanism 200 comprises a housing 201, a brake pin shaft 202 and a locking shaft 203. The housing 201 is internally configured with a first channel 2011 and a second channel 2012 which are in communication with each other and arranged at a preset angle, which can be 90 degrees or any other angle as long as the two channels are not parallel.

[0103] The brake pin shaft 202 is installed in the first channel 2011 and can move along the first channel 2011. A brake hole 2021 is arranged on the outer circumferential surface of the brake pin shaft 202, so that the brake pin shaft 202 can be switched between a retracted unlocking state relative to the housing 201 and an extended locking state relative to the housing 201.

[0104] The locking shaft 203 is installed in the second channel 2012 and can move along the second channel 2012 to limit the brake pin shaft 202. When the end of the locking shaft 203 is inserted into the brake hole 2021, the locking shaft 203 limits the movement of the brake pin shaft 202 in the first channel 2011, so that the brake pin shaft 202 remains in the unlocking state. When the locking shaft 203 is disengaged from the brake hole 2021, the brake pin shaft 202 can move freely along the first channel 2011 to the locking state.

[0105] As shown in Figure 15 and Figure 16 The locking button 206 is arranged on the lift car body 100. Part of the locking button 206 extends out of the lift car body 100, and the other part of the locking button 206 extends into the interior of the lift car body 100. The part of the locking button 206 extending into the lift car body 100 is adapted to abut against the lever 205. The middle part of the lever 205 is rotatably connected to the housing 201, and the end of the lever 205 away from the locking button 206 is rotatably connected to the locking shaft 203.

[0106] When the locking mechanism 200 needs to be locked, the locking button 206 is pressed downward to trigger the lever 205 to rotate around the position rotatably connected to the housing 201, so that the locking shaft 203 moves away from the brake hole 2021, the end of the locking shaft 203 is disengaged from the brake hole 2021, and the locking shaft 203 and the brake pin shaft 202 are disengaged. A pushing force is applied to the brake pin shaft 202 to move the brake pin shaft 202 along the first channel 2011 until the end of the brake pin shaft 202 extends out of the first channel 2011. After the end of the brake pin shaft 202 extends out of the first channel 2011, it is clamped in the limiting hole of the guide (not shown in the figure), and the lifting device is locked on the guide.

[0107] As shown in Figure 15 and Figure 16As shown, in some embodiments of the present application, specifically, the end of the second channel 2012 away from the first channel 2011 is expanded in diameter to form a step inside the second channel 2012; the locking shaft 203 is circumferentially provided with a ring of limiting platforms abutting against the step; the first spring cover 212 is mounted at the end of the second channel 2012 away from the first channel 2011, and the first spring 204 is circumferentially sleeved on the locking shaft 203, and the first spring cover 212 is adapted to abut the first spring 204 against the limiting platform and make the limiting platform abut against the step.

[0108] When the locking shaft 203 is fixed relative to the brake pin shaft 202 (i.e. the end of the locking shaft 203 is inserted into the brake hole 2021 of the brake pin shaft 202), at this time, the first spring 204 is in a relaxed state, and when the brake pin shaft 202 needs to be locked, the locking button 206 on the lifting device is pressed downward to trigger the lever 205 to rotate around the position rotationally connected to the housing 201, so that the end of the locking shaft 203 is separated from the brake pin shaft 202, and the fixing between the two is released, and the brake pin shaft 202 is applied with a force to perform a locking action. When the locking shaft 203 is pulled upward, the limiting platform of the locking shaft 203 also moves upward, and the first spring 204 is pressed by the limiting platform of the locking shaft 203 toward the first spring cover 212, and the first spring 204 is in a compressed state, and the brake pin shaft 202 is switched to a locked state.

[0109] When the brake pin shaft 202 is unlocked and returns to the original position, at this time, the limiting platform of the locking shaft 203 is pushed by the first spring 204, and the locking shaft 203 is moved toward the brake hole 2021 of the brake pin shaft 202 until the limiting platform abuts against the step, and the end of the locking shaft 203 is inserted into the brake hole 2021, at this time, the compressed state of the first spring 204 is released, and the first spring 204 is in a relaxed state, and the automatic fixing of the brake pin shaft 202 and the locking shaft 203 after unlocking can be achieved.

[0110] The locking mechanism 200 provided by the embodiment of the present application realizes the locking function under the action of the lever principle, when one end of the lever 205 is pressed downward and inclined, the other end of the lever 205 drives the locking shaft 203 to move upward, so that the locking shaft 203 and the brake pin shaft 202 are separated, and the brake pin shaft 202 is popped out to realize locking. When the one end of the lever 205 is no longer subjected to downward pressure, under the action of the elastic restoring force of the first spring 204, the locking shaft 203 moves downward until it is inserted into the brake hole 2021 to limit the brake pin shaft 202 in the first channel 2011.

[0111] As Figure 15 and Figure 16As shown, specifically, the flexible cable 208 is connected to the brake pin shaft 202, penetrates through the first channel 2011, and extends to the outside of the shell 201. An end of the flexible cable 208 is provided with a flexible cable fixing seat 210, and the handle 211 is movably connected to the flexible cable fixing seat 210. Meanwhile, the second spring 207 is arranged in the first channel 2011, and the flexible cable 208 can pull the brake pin shaft 202 to the unlocking state to compress the second spring 207 to cause elastic deformation, and the second spring 207 can drive the brake pin shaft 202 to move to the locking state under the elastic restoring action.

[0112] An axial through connection hole is formed in the brake pin shaft 202, and a second annular protrusion (which can also be other limiting structures for fixing and limiting one end of the second spring 207) is arranged on the inner surface of the through connection hole, so as to divide the through connection hole into a first connection hole and a second connection hole that are in communication with each other, and the second spring 207 is installed in the first connection hole.

[0113] When the locking mechanism 200 needs to release the locking state, the handle 211 can be pulled to move the flexible cable fixing seat 210 to drive the flexible cable 208 to move, and the brake pin shaft 202 is pulled to retract into the first channel 2011. When the brake hole 2021 of the brake pin shaft 202 is aligned with the locking shaft 203, the locking shaft 203 automatically moves downward, and the end of the locking shaft 203 is in the brake hole 2021 of the brake pin shaft 202. At this time, the second spring 207 is in a compressed state and has the ability of elastic recovery, that is, the two ends of the second spring 207 abut against the second annular protrusion and a fixed point in the first channel 2011 respectively. The fixed point can be a point on the inner surface of the first channel 2011 or a fixing device arranged on the inner surface.

[0114] As shown, Figure 16 In some embodiments of the present application, a first annular protrusion is arranged on the inner surface of the first channel 2011 to divide the first channel 2011 into a first sub-channel and a second sub-channel that are in communication with each other, the brake pin shaft 202 is installed in the second sub-channel, the flexible cable 208 penetrates through the first sub-channel and the second sub-channel, a third spring 209 is arranged in the first sub-channel and is sleeved on the flexible cable 208, a flexible cable pressing sleeve and a second spring pressing cover 213 are arranged at the two ends of the third spring 209 respectively, the flexible cable pressing sleeve is fixed to the flexible cable 208 and is adapted to move with the flexible cable 208, and the second spring pressing cover 213 is fixed at the port position of the first sub-channel.

[0115] When the locking mechanism 200 needs to release the locking state, the handle 211 is pulled to move the cable fixing seat 210 to retract the brake pin shaft 202 into the first channel 2011, and the end of the locking shaft 203 is located in the brake hole 2021 of the brake pin shaft 202 to limit the position of the brake pin shaft 202. If the handle 211 pulls the excess part of the cable 208 out of the shell 201, the third spring 209 is pressed by the cable pressing sleeve and the second spring pressing cover 213 to elastically deform, that is, one end of the third spring 209 abuts against the second spring pressing cover 213, and the other end of the third spring 209 is pressed by the cable pressing sleeve and the gasket, at this time, the third spring 209 is in a compressed state, that is, the third spring 209 has the ability to restore the elastic deformation. When the handle 211 is released, the elastic deformation of the third spring 209 is restored to retract the excess cable 208 outside the shell 201 into the shell 201.

[0116] As shown in Figure 15 and Figure 16 , in some embodiments of the present application, a notch is provided on the second spring pressing cover 213, which can be accommodated in the notch when the handle 211 is not working, so as not to affect the operation of the lifting equipment.

[0117] As shown in Figure 15 and Figure 16 , in some embodiments of the present application, since the brake pin shaft 202 is a pin shaft type cylindrical structure, it is easy to rotate in the first channel 2011, so that the locking shaft 3 cannot be effectively aligned with the brake hole 2021 to limit the position. Therefore, an anti-rotation limiting component 214 is arranged on the outside of the shell 1 and corresponds to the position of the first channel 2011 to prevent the brake pin shaft 202 from turning.

[0118] Specifically, the anti-rotation limiting component 214 includes a limiting block 2141 and a pin shaft 2142, and the limiting block 2141 is fixed on the outer surface of the shell 201. A guide groove (not shown in the figure) is formed on the outer circumferential surface of the brake pin shaft 202 along the axial direction of itself, one end of the pin shaft 2142 is inserted into the guide groove, and the other end of the pin shaft 2142 passes through the shell 201 and is connected with the limiting block 2141.

[0119] By arranging the pin shaft 2142, the pin shaft 2142 cooperates with the guide groove of the brake pin shaft 202 to realize guided movement, so that the brake pin shaft 202 can only move along the extension direction of the guide groove (i.e. the axial direction of the brake pin shaft 202), and cannot rotate in the circumferential direction, thereby ensuring that the brake hole 2021 accurately appears in the axial direction of the locking shaft 3.

[0120] In addition to the above-mentioned embodiments, the brake pin shaft 202 and the first channel 2011 can also be made into other structures that are not cylindrical, such as rectangular cross-section or other structures that do not rotate relatively.

[0121] The lifting device provided by the embodiment of the present application is used in the following way: when the worker gets on the lifting car body 100 to perform the lifting operation along the guide piece, the worker presses the locking button 206 when locking is needed, the lower end of the locking button 206 presses one end of the lever 205 downward, the other end of the lever 205 lifts the locking shaft 203 upward, the locking shaft 203 is separated from the locking hole 2021 of the brake pin shaft 202, the brake pin shaft 202 moves to the right under the action of the second spring 207, extends out of the first channel 2011, and finally the end of the brake pin shaft 202 is clamped in the limiting hole of the guide piece, so that the lifting car body 100 is locked and cannot move, and is stopped at a certain position on the guide piece.

[0122] When the lifting device is repaired, the handle 211 is pulled, the handle 211 drives the brake pin shaft 202 to move to the left through the flexible cable 208, the end of the brake pin shaft 202 is separated from the guide piece to release the locking, the brake pin shaft 202 returns to the initial position, and the limiting is realized by inserting the locking shaft 203 into the locking hole 2021 of the brake pin shaft 202. After the handle 211 is released, the handle 211 can collect the excess flexible cable 208 into the shell 201 under the action of the third spring 209, so as to ensure the safety of the lifting device during operation.

[0123] As shown in Figures 1 to 3 , and Figure 17 and Figure 18 , in some embodiments of the present application, the lifting device further comprises a pedal assembly 300, and the pedal assembly 300 comprises a pedal component 301, a pedal support 302 and a lower contour component 303.

[0126] Further, an alarm device can be set in the control system, and a weighing limit value of the pedal 3011 is set, when the weighing limit value is exceeded, the alarm device alarms to warn the staff that the weight is overweight, so as to timely adjust the article or the person on the pedal 3011 to reach the case of not overweight.
