DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and in combination with specific embodiments.

[0025] It should be noted that, unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be understood as having the common meaning in the field of the present application to which they belong. The terms "first", "second", and similar terms in the present application do not denote any order, quantity, or importance, but are merely used to distinguish different components. The terms "comprise", "include", and similar terms mean that the elements or objects before the term encompass the elements or objects listed after the term and their equivalents, without excluding other elements or objects. The terms "connected" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right", and the like are only used to represent relative positional relationships, which may change accordingly when the absolute position of the described object changes.

[0026] As described in the background, at present, when working on the lower baffle of the generator ventilation system, it mainly relies on manual lifting. The maintenance personnel need to bend down or squat down, and use both hands to support the baffle, to assist other personnel to carry out disassembly, repair work. In some cases, a simple lever tool is temporarily used for assistance, one end of the long rod is placed under the baffle, and the other end is pressed down by manpower to lift up, which has poor stability and needs to find a fulcrum and cooperate with many people. There are many shortcomings in the current installation or repair work of the lower baffle of the ventilation system in the generator: 1. High labor cost: manual or with the help of a simple lever to lift the baffle, a large amount of physical effort is required, and many workers are needed to cooperate, which is low in efficiency, and long-time operation can easily lead to personnel fatigue and increase labor cost; 2. Poor precision: manual lifting is difficult to accurately control the height and levelness of the baffle, and in subsequent installation, it is easy to adjust repeatedly due to position deviation, which prolongs the operation time; 3. Low safety: the lower baffle is heavy, and the lifting has the risk of dropping and injuring personnel. The fulcrum of the temporary lever tool is unstable, which may fall during operation, endangering the safety of the operator.

[0027] Therefore, the present application provides an installation and lifting tool for the lower baffle of the generator to avoid manual lifting, reduce labor cost, and improve lifting precision and safety.

[0028] The following is described in detail through one or more specific embodiments.

[0029] In some embodiments, an installation and lifting tool for the lower baffle of the generator, as shown in Figure 1 , Figure 2 and Figure 3 , comprises:

[0030] a tray 100 having a limiting piece 110 for limiting the to-be-lifted lower baffle;

[0031] The lifting structure 200 is connected to the side of the tray 100 opposite to the limiting member 110;

[0032] The movable chassis 300 is connected to the end of the lifting structure 200 away from the tray 100, and has a leveling mechanism 310 for adjusting its levelness.

[0033] Specifically, the tray 100 is the top of the installation and lifting tool, and contacts the lower windshield to be lifted. It is the main structure for lifting the lower windshield to be lifted. The lifting structure 200 is used to adjust the height of the tray 100, thereby adjusting the lifting height of the installation and lifting tool, so that the lifting height of the installation and lifting tool is the same as the installation height of the lower windshield to be lifted, so as to facilitate the subsequent installation or maintenance of the lower windshield to be lifted.

[0034] The mobile chassis 300 can move the pallet 100 and the lifting structure 200, which facilitates the movement of the installation and lifting tool by installation and maintenance personnel, so that the position of the installation and lifting tool corresponds to the installation position of the lower windshield to be lifted, thereby improving the lifting accuracy of the installation and lifting tool and improving the installation and maintenance efficiency of the lower windshield to be lifted.

[0035] The mobile chassis 300 is equipped with a leveling mechanism 310, which facilitates the adjustment of the level of the mobile chassis 300 by installation and maintenance personnel, thereby facilitating the adjustment of the level of the tray 100. This ensures that the tray 100 can maintain a horizontal position to support the lower wind deflector to be supported, keeping the lower wind deflector level during installation or maintenance. This avoids the lower wind deflector's levelness affecting installation and maintenance, and thus improves the installation efficiency of the lower wind deflector.

[0036] In this embodiment, the height of the lower baffle to be lifted on the tray 100 is adjusted by the lifting structure 200 so that the height of the lower baffle to be lifted is the same as the height of its intended installation position, which facilitates installation and maintenance. The movable chassis 300 facilitates the movement of the lifting position of the installation lifting tool. The horizontal adjustment mechanism 310 on the movable chassis 300 adjusts the horizontality of the movable chassis 300, thereby adjusting the horizontality of the tray 100, so that the tray 100 can horizontally lift the lower baffle to be lifted. The limiting member 110 on the tray 100 limits the lower baffle to be lifted, so that the position of the lower baffle to be lifted on the tray 100 is stable, which facilitates installation and maintenance. At the same time, it can also be positioned based on the installation position of the lower baffle to be lifted, which helps to improve the installation and maintenance efficiency of the lower baffle to be lifted. This application, by setting up a horizontal adjustment mechanism 310 and a limiting component 110, avoids the need for manual lifting to maintain horizontality and stability, thereby reducing labor costs and significantly improving the installation and maintenance efficiency of the windshield under the load.

[0037] In some embodiments, such as Figure 1 As shown, the horizontal adjustment mechanism 310 includes a horizontal bubble 311 and a plurality of adjustment rods 312. The horizontal bubble 311 is located on the side of the movable chassis 300 connected to the lifting structure 200. The plurality of adjustment rods 312 are evenly distributed along the circumference of the movable chassis 300. Each adjustment rod 312 is connected to a moving part 320 at one end away from the tray 100.

[0038] Specifically, multiple adjusting rods 312 connect the movable chassis 300 and the movable component 320 together, enabling the movable chassis 300 to move under the action of the movable component 320. Furthermore, the multiple adjusting rods 312 can adjust the distance between the movable chassis 300 and the movable component 320, allowing the movable component 320 to adjust its distance from the movable chassis 300 under different working conditions. The multiple adjusting rods 312 work together to keep the movable chassis 300 horizontal. Correspondingly, the lifting structure 200 and the tray 100 can also remain horizontal. The tray 100 can horizontally lift the lower wind deflector to be lifted, keeping it horizontal for installation or maintenance, thus improving the installation and maintenance efficiency of the lower wind deflector.

[0039] It should be noted that the level bubble 311 is located on the movable chassis 300, allowing the operator to determine whether the movable chassis 300 is level by checking the position of the level bubble 311. It also assists the operator in adjusting the adjusting rod 312 to adjust the movable chassis 300 to a level state, which helps improve the adjustment efficiency of the leveling mechanism 310, and thus improves the efficiency and practicality of the installation and lifting tool.

[0040] Furthermore, multiple adjusting rods 312 jointly support the movable chassis 300 to keep it horizontal. Therefore, the multiple adjusting rods 312 are evenly distributed around the circumference of the movable chassis 300 to facilitate the operator's adjustment of the adjusting rods 312 to keep the movable chassis 300 horizontal. Considering adjustment efficiency and support stability, setting three adjusting rods 312 is the optimal solution. Three adjusting rods 312 provide strong support stability for the movable chassis 300, and the number of adjusting rods 312 is relatively small. When the operator adjusts the adjusting rods 312 to keep the movable chassis 300 horizontal, the number of adjustments is relatively small, which helps to improve the efficiency and practicality of the installation and lifting tool.

[0041] Finally, the movable component 320 includes a connected support plate and wheels. The support plate is connected to the adjusting rod 312 to bear the pressure on the adjusting rod 312 and transmit the pressure to the wheels. The support plate enhances the load-bearing capacity and service life of the movable component 320. In terms of improving the ease of use of the installation lifting tool, the wheels are fixed swivel casters. The swivel casters improve its ease of movement, which in turn improves the efficiency of the installation lifting tool and thus its overall efficiency. Furthermore, by setting the wheels as fixed swivel casters, the lifting position of the installation lifting tool can be fixed after the lifting position is determined, preventing the wheels from moving and thus fixing the lifting position of the installation lifting tool. This prevents the installation lifting tool from moving during the lifting process, which could affect its lifting accuracy.

[0042] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the adjusting rod 312 includes a threaded rod, and the movable chassis 300 is provided with a connecting through hole for the threaded rod to pass through. A support nut 313 for supporting the movable chassis 300 is threadedly connected to the threaded rod, and the support nut 313 is located below the movable chassis 300.

[0043] Specifically, the threaded rod passes through the connecting through hole and connects to the movable base 300. The support nut 313 is sleeved around the threaded rod and located below the movable base 300, abutting against the movable base 300, so that the movable base 300 is stably connected to the threaded rod under the support of the support nut 313. By rotating the support nut 313 to adjust its position on the threaded rod, the connection length between the movable base 300 and the threaded rod can be adjusted. By adjusting the height of the adjusting rod 312 between the moving part 320 and the movable base 300, the horizontal state of the movable base 300 can be adjusted.

[0044] It should be noted that a stabilizing nut 314 is also fitted around the end of the threaded rod that passes through the connecting through hole, that is, the part located above the movable chassis 300. The stabilizing nut 314 is threadedly connected to the threaded rod and abuts against the top surface of the movable chassis 300, so that the threaded rod is stably connected to the movable chassis 300 under the combined action of the supporting nut 313 and the stabilizing nut 314.

[0045] In this embodiment, the threaded rod and the support nut 313 work together to connect with the movable chassis 300. By rotating the support nut 313, the support height of the adjusting rod 312 on the movable chassis 300 can be adjusted, thereby facilitating the adjustment of the level of the movable chassis 300. This improves the simplicity of the level adjustment mechanism 310, has a low cost, and enhances the practicality of the installation and lifting tool.

[0046] In some embodiments, such as Figure 1 As shown, the limiting member 110 includes a first limiting protrusion 111 and a second limiting protrusion 112 arranged in parallel with each other. The first limiting protrusion 111 and the second limiting protrusion 112 have the same arc structure.

[0047] Specifically, the lower windshield to be lifted has a fan-shaped structure, with one set of two opposite edges being straight lines and the other set of two opposite edges being parallel arcs. Therefore, the tray 100 is provided with opposite first limiting protrusions 111 and second limiting protrusions 112. The first limiting protrusions 111 and second limiting protrusions 112 are the same arc structure to adapt to the lower windshield to be lifted. The distance between the first limiting protrusions 111 and second limiting protrusions 112 is adapted to the distance between the two arc structures of the lower windshield, so that the lower windshield is stably placed on the tray 100 under the limiting action of the first limiting protrusions 111 and second limiting protrusions 112, and does not slip off the tray 100 due to the adjustment of the horizontal adjustment mechanism 310. This can improve the installation or maintenance efficiency of the lower windshield to be lifted by the installation lifting tool. In addition, the first limiting protrusion 111 and the second limiting protrusion 112 enable the staff to quickly locate the installation position of the windshield to be lifted based on the first limiting protrusion 111 and the second limiting protrusion 112, which helps to improve the efficiency of the installation lifting tool.

[0048] Based on this, multiple anti-slip protrusions are evenly arranged between the first limiting protrusion 111 and the second limiting protrusion 112, which can further improve the stability of the windshield to be lifted on the tray 100.

[0049] In some embodiments, the side of the tray 100 away from the lifting structure 200 is a planar structure.

[0050] Specifically, the side of the tray 100 away from the lifting structure 200, and the portion located between the first limiting protrusion 111 and the second limiting protrusion 112, is a planar structure. The lower baffle to be lifted is located between the first limiting protrusion 111 and the second limiting protrusion 112 and abuts against the planar structure, so that the tray 100 lifts the lower baffle to be lifted. The planar structure can prevent the unevenness of the lifting surface of the tray 100 from affecting the levelness of the lower baffle to be lifted, thereby helping to ensure the levelness of the lower baffle to be lifted, so that the lower baffle to be lifted can be stably lifted for installation or maintenance. The planar structure helps to improve the practicality and levelness of the installation lifting tool.

[0051] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the lifting structure 200 includes a lifting column 210 and a limiting support groove 220. The limiting support groove 220 is located on the mobile chassis 300. One end of the lifting column 210 is connected to the tray 100, and the other end is located in the limiting support groove 220 and is lifted and lowered in connection with the limiting support groove 220.

[0052] Specifically, the lifting column 210 is connected to the tray 100, and the limiting support groove 220 is connected to the mobile chassis 300. The lifting column 210 and the limiting support groove 220 are connected in a lifting manner so that the lifting column 210 can be stably lifted and lowered within the limiting support groove 220 to realize the lifting and lowering of the tray 100. This enables the installation lifting tool to have a lifting function, allowing the lower wind deflector to be lifted to rise and fall with the tray 100 to meet its lifting and lowering needs during installation or maintenance.

[0053] It should be noted that the lifting connection between the lifting column 210 and the limiting support groove 220 is adjustable and stable to ensure the stability of the windbreak plate to be lifted on the tray 100.

[0054] In some embodiments, such as Figure 2 and Figure 3 As shown, the outer side wall of the lifting column 210 is provided with a slide rail 211, and the slide rail 211 is provided with a ball bearing 212, which abuts against the inner wall of the limiting support groove 220.

[0055] Specifically, the lifting column 210 can rise and fall within the limiting support groove 220. The outer periphery of the lifting column 210 is adapted to the inner periphery of the limiting support groove 220. In order to reduce the friction between the outer periphery of the lifting column 210 and the inner wall of the limiting support groove 220, and to improve the smoothness of the lifting column 210 during the rising and falling process within the limiting support groove 220, a slide rail 211 is provided on the outer wall of the lifting column 210. A plurality of balls 212 are provided in the slide rail 211. The balls 212 protrude relative to the slide rail 211 and abut against the inner wall of the limiting support groove 220. When the lifting column 210 rises and falls relative to the limiting support groove 220, the balls 212 rotate within the slide rail 211 to increase the smoothness between the lifting column 210 and the limiting support groove 220, so that the lifting column 210 rises and falls smoothly within the limiting groove.

[0056] It should be noted that the slide rail 211 is located on the side wall of the lifting column 210 near the bottom, which ensures that the ball bearing 212 is not affected by the lifting of the lifting column 210 in its contact with the limiting support groove 220. In addition, the slide rail 211 can also be vertically installed on the side wall of the lifting column 210 and adapted to the height of the lifting column 210, so as to avoid the lifting of the lifting column 210 affecting the contact between the ball bearing 212 and the limiting support groove 220.

[0057] Furthermore, the ball bearing 212 is stably positioned within the slide rail 211, and the end of the slide rail 211 is closed to prevent the ball bearing 212 from rolling out of the slide rail 211.

[0058] In some embodiments, such as Figure 3 As shown, the side wall of the limiting support groove 220 is provided with a plurality of parallel lifting slide grooves 221, and the lifting column 210 is provided with a threaded groove 213 corresponding to the lifting slide groove 221. The bolt passes through the lifting slide groove 221 and is threadedly connected to the threaded groove 213 to fix the lifting column 210 to the limiting support groove 220.

[0059] Specifically, the lifting column 210 and the limiting support groove 220 are connected by the lifting slide 221 and the threaded groove 213. When the lifting column 210 is operated to rise or fall to the corresponding position relative to the limiting support groove 220, the bolt is threaded through the lifting slide 221 and the threaded groove 213, and the nut of the bolt abuts against the outer wall of the lifting slide 221 to fix the lifting column 210 and the limiting support groove 220, so that the lifting column 210 can stably and horizontally lift the lower wind deflector to be lifted.

[0060] It should be noted that multiple lifting slides 221 are arranged vertically side by side, which can prevent the lifting column 210 from rotating relative to the limiting support groove 220, thereby enhancing the connection stability between the lifting column 210 and the limiting support groove 220.

[0061] In addition, in order to enhance the connection strength between the lifting column 210 and the limiting support groove 220, each lifting slide 221 may correspond to multiple threaded grooves 213.

[0062] In some embodiments, such as Figure 1As shown, the lifting column 210 and the limiting support groove 220 are connected in a lifting manner through a gear and rack structure. The gear 214 is connected to the lifting column 210 through a rotating shaft. The rack 222 is located on the limiting support groove 220. The gear 214 is meshed with the rack 222. By rotating the gear 214, the lifting column 210 is raised or lowered relative to the limiting support groove 220.

[0063] Specifically, the lifting column 210 and the limiting support groove 220 are connected in a lifting manner through the gear and rack structure. The gear and rack structure includes a gear 214 and a rack 222 that are meshed together. The gear 214 and the lifting column 210 are connected through the rotating shaft, that is, the rotating shaft passes through the lifting column 210 and is fixedly connected to the gear 214 at its end. The rotating shaft can rotate with the gear 214. The rack 222 is located on the side wall of the limiting support groove 220 and is arranged vertically. When the gear 214 rotates, the gear 214 moves on the rack 222, thereby driving the lifting column 210 to move within the limiting support groove 220, realizing the lifting of the lifting column 210 relative to the limiting support groove 220.

[0064] In addition, both ends of the rotating shaft extend relative to the lifting column 210, and at least one end is connected to the gear 214.

[0065] It should be noted that the rotation of the gear 214 can be achieved by the operator applying rotational force or by the drive motor applying rotational force.

[0066] In this embodiment, the lifting column 210 and the limiting support groove 220 are connected by a gear 214 and rack 222 structure. The lifting column 210 can be raised or lowered by rotating the gear 214, which can reduce the workload of the staff and improve the work efficiency of the installation and lifting tool.

[0067] In some embodiments, such as Figure 1 and Figure 2 As shown, a vertical slide groove 223 is provided on the side wall of the limiting support groove 220, the rack 222 is located on the vertical slide groove 223, and a rotating handle 216 is connected to the side of the gear 214 away from the lifting column 210. The rotating handle 216 is set through the vertical slide groove 223.

[0068] The lifting column 210 is provided with a fixing groove, and the gear 214 is provided with a positioning through hole 218. The positioning through hole 218 and the fixing groove are connected by a fixing member 219 to fix the gear 214 and the lifting column 210.

[0069] Specifically, a vertical slide groove 223 is provided on the side wall of the limiting support groove 220, so that the rack 222 is arranged parallel to the vertical slide groove 223 and located on the vertical side wall of the vertical slide groove 223. Thus, the gear 214 can be exposed through the vertical slide groove 223. The side of the gear 214 away from the lifting column 210 is connected to the rotating handle 216. The rotating handle 216 can extend through the vertical slide groove 223 so that the user can rotate the rotating handle 216, thereby rotating the gear 214 and controlling the gear 214 and the lifting column 210 to rise and fall relative to the limiting support groove 220.

[0070] Based on this, in order to enhance the meshing stability of the gear 214 and the rack 222, a positioning through hole 218 is provided on the gear 214, and a fixing groove is provided on the lifting column 210. When the gear 214 rotates to the corresponding position, the fixing member 219 passes through the positioning through hole 218 and is fixedly connected to the fixing groove, which can position the gear 214 and prevent the gear 214 from rotating randomly, which helps to enhance the stability of the lifting structure 200.

[0071] It should be noted that the positioning through hole 218 can be an arc-shaped through hole arranged around the center of the gear 214, the fixing groove can be a threaded groove 213 adapted to the width of the arc-shaped through hole, and the fixing member 219 can be a bolt. The bolt passes through the arc-shaped through hole and is threadedly connected to the threaded groove 213, so that the fixing member 219 is stably located on the lifting column 210, which helps to enhance the lifting stability of the installation lifting tool.

[0072] In addition, two fixing slots can be symmetrically arranged above and below or to the left and right of the rotating shaft, and the positioning through hole 218 can be an arc-shaped through hole with a corresponding arc of 180°. This ensures that the gear 214 has a corresponding fixing slot when it rotates to any position, for the fixing member 219 to connect and fix the gear 214.

[0073] The following describes the usage process of the installation and lifting tool for the lower windshield provided in this application based on the above embodiments.

[0074] The installation lifting tool is moved to the installation space of the lower baffle in the generator's ventilation system. The lower baffle to be lifted is placed on the tray 100, and the limiting member 110 contacts the lower baffle to be lifted for limiting. Then, based on the installation position and installation shape of the lower baffle to be lifted, the installation lifting tool is moved and rotated so that the lower baffle to be lifted is basically aligned with its installation position. Then, based on the level bubble 311, the multiple adjusting rods 312 of the leveling structure are adjusted so that the moving chassis 300 and the tray 100 remain horizontal. Then, the lifting structure 200 is operated to raise the tray 100 to coincide with the installation position of the lower baffle to be lifted. Finally, the installation of the lower baffle can be performed by operating any one of the following steps.
