Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Figure 1 This is a schematic diagram of the structure of a coil press lifting operation platform provided in an embodiment of the present invention, as shown below. Figure 1-3 As shown, the lifting operation platform may include a lifting platform component 1, a telescopic pedal component 2, and a follow-up inclined ladder component 3. Multiple telescopic pedal components 2 are slidably connected to the lifting platform component 1 and extend and retract along its circumference to accommodate coils 100 of different sizes and specifications. The lifting platform component 1 is connected to the follow-up inclined ladder component 3 and is used to drive the follow-up inclined ladder component 3 to move horizontally.

[0038] In the above embodiment, the size adjustment of the lifting platform component 1 and the telescopic pedal component 2 is used to facilitate the operation of coils of different sizes and specifications by the operator. At the same time, the follow-up inclined ladder component 3 is integrated into the operating platform. The vertical driving force of the lifting platform is converted into the horizontal driving force of the follow-up inclined ladder, which drives the follow-up inclined ladder to move horizontally while the platform is rising and falling. This meets the needs of the operator to enter and exit the lifting platform via the follow-up inclined ladder when the lifting platform is at different heights.

[0039] As an optional implementation, the lifting platform component 1 includes a first drive motor 101, a first reducer 102, a first transmission shaft 103, a screw jack 104, a column frame assembly 106, a platform assembly 107, and a lower platform 108. The output end of the first drive motor 101 is connected to the first reducer 102. The first reducer 102 is connected to the screw jack 104 through the first transmission shaft 103. One end of the lead screw 105 of the screw jack 104 is connected to the base of the column frame assembly 106 and passes through the platform assembly 107. The platform assembly 107 is movably connected to the column frame assembly 106 and moves along its axial direction under the drive of the lead screw 105. The column frame assembly 106 is installed on the lower platform 108.

[0040] Specifically, such as Figure 4-5 As shown above, the specific structural form of the lifting platform component 1 is given. The lifting movement of the platform assembly 107 is realized by the screw jack 104. The overall structure composed of the column frame assembly 106 and the lower platform 108 is used to place the coil 100.

[0041] Since the screw jack 104 has a conventional structure, its specific structure and working principle will not be described in detail here. One end of the lead screw 105 of the screw jack 104 is rotatably connected to the column frame assembly 106 through the lead screw seat 121.

[0042] The specific way in which the platform component 107 is movably connected to the column frame component 106 can be a sliding connection or a rolling connection, and no specific limitation is made here.

[0043] As an optional implementation, the screw jack 104 also includes a moving nut 109 and a moving nut mounting base 110. The moving nut 109 is screwed to the lead screw 105 and moves along its axial direction. The moving nut 109 is mounted on the moving nut mounting base 110, and the moving nut mounting base 110 is fixedly connected to the platform assembly 107.

[0044] Specifically, such as Figure 4-10 As shown, the rotational motion of the lead screw 105 is converted into the lifting motion of the platform assembly 107 through the cooperation between the motion nut 109 and the motion nut mounting base 110.

[0045] As an optional implementation, the lifting platform component 1 also includes guide rollers 111 and guide roller mounting brackets 112. The guide rollers 111 are mounted on the lower end face of the platform assembly 107 via the guide roller mounting brackets 112 and are tactilely connected to the column frame assembly 106.

[0046] Specifically, such as Figure 4-10 As shown, the platform assembly 107 can roll along the surface of the column frame assembly 106 while being raised and lowered by the cooperation between the guide roller 111 and the guide roller mounting bracket 112, so as to avoid horizontal movement during the raising and lowering process and play a guiding and limiting role.

[0047] As an optional implementation, the lifting platform component 1 also includes a connecting flange 113 and a first coupling 114, and the first drive motor 101 is connected to the first reducer 102 through the connecting flange 113 and the first coupling 114.

[0048] Specifically, such as Figure 4-10 As shown above, the specific connection method between the first drive motor 101 and the first reducer 102 is given, but the technical solution of this application is not limited to this.

[0049] As an optional implementation, the lifting platform component 1 also includes a right-angle commutator 115, a second coupling 116, and a third coupling 117. The end of the first drive shaft 103 is connected to the right-angle commutator 115 through the second coupling 116, and the right-angle commutator 115 is connected to the input end of the screw jack 104 through the third coupling 117.

[0050] Specifically, such as Figure 4-10 As shown, the horizontal driving force of the first drive motor 101 is converted into the vertical rotational force of the screw jack 104 through the right-angle commutator 115. The second coupling 116 and the third coupling 117 are both used to realize the torque transmission between the shafts. The technical solution of this application is not limited to this.

[0051] In addition, to ensure the stability of the platform assembly 107 during the lifting process, two sets of screw lifts 104 are installed, such as... Figure 8 As shown, the two sets of screw jacks 104 can share the same first drive motor 101. In this case, a fourth coupling 118, a second drive shaft 119, and a bearing 120 need to be added. The horizontal output end of one screw jack 104 is connected to the second drive shaft 119 through the fourth coupling 118 and is used to drive it to rotate. The input end of the other screw jack 104 is connected to the end of the second drive shaft 119. The second drive shaft 119 is installed through the bearing 120, thereby driving the other screw jack 104 at the end to rotate, which in turn drives its corresponding lead screw 105 to rise and fall. Finally, the same drive motor drives the synchronous lifting and lowering of four sets of lead screws 105.

[0052] As an optional implementation, the telescopic pedal component 2 includes a telescopic pedal 201, a gear and rack pair 202, a second reducer 203, a second drive motor 204, and a guide rail slider pair 205. The telescopic pedal 201 is connected to the platform assembly 107 through the guide rail slider pair 205. The second drive motor 204 is connected to the gear and rack pair 202 through the second reducer 203 and is used to drive the gear in the gear and rack pair 202 to move along the length direction of the rack. The rack in the gear and rack pair 202 is connected to the telescopic pedal 201 and moves synchronously.

[0053] Specifically, such as Figure 4-10 As shown above, the specific structural form of the telescopic pedal component 2 is given. Through the cooperation between the second drive motor 204 and the gear rack pair 202, the telescopic pedal 201 can move horizontally along the guide rail slider pair 205, thereby enabling the operator to perform related operations on the coils 100 of different sizes.

[0054] like Figure 3 As shown, the end face of the telescopic pedal 201 that contacts the coil 100 is arc-shaped to accommodate the cylindrical coil 100.

[0055] The gear and rack pair 202 includes a gear and a rack that cooperate with each other, with the gear rolling along the length of the rack; the guide rail and slider pair 205 includes a slider and a guide rail that cooperate with each other, with the slider sliding along the length of the guide rail. Since both the gear and rack pair 202 and the guide rail and slider pair 205 are conventional structures, their specific structures and working principles will not be elaborated upon here.

[0056] like Figure 3 As shown, four sets of telescopic pedal components 2 are respectively installed on the four sides of the rectangular platform assembly 107. The four telescopic pedals 201 can move independently through the corresponding four gear rack pairs 202, and can move asynchronously or synchronously.

[0057] As an optional implementation, the telescopic pedal component 2 also includes a speed reducer mounting plate 206, through which the second speed reducer 203 and the second drive motor 204 are connected to the platform assembly 107.

[0058] Specifically, such as Figure 4-10 As shown, the reducer mounting plate 206 is fixedly installed on the platform assembly 107, thereby fixing the second reducer 203 and the second drive motor 204 on the platform assembly 107.

[0059] As an optional implementation, the follower inclined ladder component 3 includes a follower inclined ladder 301, a drive slide assembly 302, a drive arm 303, a first guide rail slider pair 304, a second guide rail slider pair 305, a drive slide lower support wheel assembly 306, and a drive slide upper pressure wheel assembly 307; wherein,

[0060] One side of the follower inclined ladder 301 is rotatably connected to the drive slide assembly 302 via the drive slide upper roller assembly 307 and the drive slide lower support roller assembly 306. The other side of the follower inclined ladder 301 is slidably connected to the drive slide assembly 302 via the first guide rail slider pair 304. The drive slide assembly 302 is connected to the platform assembly 107 via the drive arm 303. The follower inclined ladder 301 is slidably connected to the column frame assembly 106 via the second guide rail slider pair 305.

[0061] Specifically, such as Figure 4-10 As shown above, the specific structural form of the follow-up inclined ladder component 3 is given. The choice of one-sided guide rail and the other-sided roller is based on considerations of assembly and actual application conditions. If two long-stroke guide rails were used, the flatness and parallelism between them would be difficult to adjust, and jamming would occur during operation. Therefore, the roller method is used, and the gap is larger than that of the guide rail, so there will be no jamming during operation. Moreover, the contact gap between the roller and the profile can be adjusted by adding or removing shims.

[0062] As an optional implementation, the follow-up inclined ladder component 3 also includes an inclined ladder roller assembly 308 and a track 309, with the follow-up inclined ladder 301 being tumbledly connected to the track 309 via the inclined ladder roller assembly 308.

[0063] Specifically, such as Figure 4-10 As shown, the inclined ladder 301 moves horizontally along a fixed direction by means of the mating installation between the inclined ladder roller assembly 308 and the track 309. The track 309 is fixed to the ground and is hidden underground.

[0064] It should be noted that the various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. The present invention is not limited to the specific steps and structures described above and shown in the figures. Furthermore, for the sake of brevity, detailed descriptions of known methods and techniques are omitted here.

[0065] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art without departing from the scope of the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
