Detailed implementation manners

[0043] Please refer to Figures 1 - 17 , the present invention provides a technical solution: a tool for laying and disassembling the floor grille of a paint baking room, including a vehicle body 1, a handle 2, a grasping assembly, a connecting assembly, and a hook 4-1 for grasping the floor grille;

[0044] At least four groups of grab hooks 4-1 are provided, and they correspond to the four corners of the vehicle body 1 respectively; each group of grab hooks 4-1 is connected to the handle 2 through a grab assembly and a connecting assembly respectively; the connecting assembly can make all the grab hooks 4-1 move synchronously;

[0045] The grab assembly includes a bracket 5 fixedly connected to the vehicle body, a shaft 9 is sleeved on the bracket 5, and a clamping unit and a driving unit are distributed on the bracket 5; the handle 2 is transmission-connected to the driving unit through the connecting assembly; the grab hook 4-1 can be driven to rotate by the driving unit and locked to rotate by the clamping unit;

[0046] The engaging unit comprises a mounting column 4 sleeved on the shaft 1 9, a grab hook 4-1 is slidably arranged on the mounting column 4 and the sliding direction is perpendicular to the axis of the mounting column 4; a circular arc groove 5-2 coaxial with the shaft 1 9 is provided on the bracket 5, a spring pin 1 4-3 inserted into the circular arc groove 5-2 is provided on the mounting column 4, a pin hole 2 5-2-1 is provided at the right end of the circular arc groove 5-2, and the spring pin 1 4-3 can be inserted into the pin hole 2 5-2-1;

[0047] The driving unit includes a driving component 1 for driving the mounting column 4 to rotate, a driving component 2 for driving the grab hook 4-1 to slide along the mounting column 4, and a resetting component for resetting the grab hook 4-1. The driving component 1, the driving component 2 and the resetting component are respectively used to make the grab hook 4-1 rotate under the ground grid, lift the ground grid and remove the ground grid.

[0048] First, press down the handle to rotate one side of the vehicle body 1 around the wheel until the vehicle body is tilted, and the wheel is stuck on the corresponding side of the ground grid, then gently release the handle to rotate the vehicle body around the wheel until the vehicle body is tilted. Figure 14 State (i.e., the vehicle body is in a horizontal state), and the following describes the specific working process with this state as the initial state before work;

[0049] In the initial state ( Figure 2 As a descriptive reference system), the status of the disassembly and assembly tools is as follows Figure 14 The vehicle body 1 is located above the ground grid, the grab hook 4-1 is located below the cylindrical beams of two adjacent ground grids, and the grab hook 4-1 is in a retracted state (such as Figure 14 , at this time, the lower end of the grab hook 4-1 is tilted to the right), the handle 2 is located at the right limit position of rotation relative to the vehicle body 1, and this position is set as a;

[0050] Then the operator pushes the handle 2. During this process, the handle 2 rotates by itself to make the drive unit synchronously drive by the connecting assembly, so that all the grab hooks 4-1 move synchronously; further, the drive assembly in all the drive units drives the grab hooks 4-1 synchronously through the transmission of the handle 2, so that all the grab hooks 4-1 rotate synchronously to the position as shown in the figure. Figure 16 The traction part of the grab hook 4-1 is placed directly below the cylindrical beam of the ground grid and maintained there.

[0051] Specifically, as Figures 13 - 17 shown, where a, b, and c respectively correspond to different positions of the rotation of the handle 2; the rotation from part a to part b is the empty stroke. The process of rotating from b to c is the docking stroke; the process of rotating from c to b is the rotation stroke, and the process of rotating from b to a is the lifting stroke. The specific working process is as follows:

[0052] Docking stroke: The transmission parts in the first driving component and the second driving component are docked with the corresponding hooks 4-1 to enter the transmission state;

[0053] Rotation stroke: The first driving component controls the installation column 4 to rotate and drives the hooks 4-1 on the installation column 4 to rotate. At the same time, the spring pin 4-3 on the installation column 4 slides along the arc groove 5-2 during the rotation of the installation column 4 until the spring pin 4-3 slides to the pin hole 5-2-1 opened at the right end of the arc groove 5-2. At this time, the spring pin 4-3 is inserted into the pin hole 5-2-1 under the action of its own elastic force, thereby making the installation column 4 and the bracket 5 engage, and locking the hooks 4-1 on the installation column 4;

[0054] Lifting stroke: The second driving component in the driving unit drives all the hooks 4-1 to move upward synchronously through the transmission of the handle 2 to Figure 17 the state (during the rotation stroke, the second driving component will also drive all the hooks 4-1 to move upward synchronously), and all the hooks 4-1 lift the floor grille by synchronously lifting the cylindrical cross beam of the floor grille;

[0055] Finally, move the vehicle body 1 to transfer the floor grille to the temporary storage area. After reaching the temporary storage area, all the hooks 4-1 are reset from Figure 17 the state to Figure 14 the state through the reset component, so that the floor grille is unloaded into the temporary storage area; then move the vehicle body 1 above a floor grille to be disassembled for another cycle.

[0056] The present invention completes the disassembly and placement process of the floor grille by controlling the retraction, verticality, upward movement, and downward movement of the hooks 4-1. During this process, the disassembly and placement of the floor grille are mainly completed by the upward and downward movement of the hooks 4-1, so that the disassembly and placement of the floor grille can be completed through the vertical position, thereby effectively preventing interference between the floor grille being disassembled and the adjacent floor grilles during the disassembly process, and at the same time effectively improving the accuracy of the placement position of the floor grille and improving the disassembly and assembly efficiency; and the process is completed by the rotation of the handle 2, which can effectively utilize the lever principle and use the vehicle body 1 to assist in the transfer, reducing the labor intensity of workers, improving work efficiency, and reducing the input of manpower.

[0057] Furthermore, the connecting component includes two connecting long shafts 22 symmetrically arranged on the left and right inside the vehicle body 1. The handle 2 is rotatably arranged on the right connecting long shaft 22. Two connecting rods one 23 symmetrically arranged front and back are rotatably connected to the left connecting long shaft 22. The connecting rods one 23 are parallel to the handle 2. Connecting rods two 24 are rotatably connected between the two connecting rods one 23 and the handle 2 respectively. Fixedly connected to the connection parts of the connecting rods one 23 and the handle 2 with the connecting long shaft 22 are gears three 25 rotatably connected to the connecting long shaft 22; the gears three 25 are respectively in transmission connection with the driving units corresponding to the four groups of hooks 4-1.

[0058] See Figure 4 As shown, the handle 2, the connecting rods one 23 and the connecting rods two 24 together form a four-bar linkage mechanism that rotates around the connecting long shaft 22. When the handle 2 is rotated, the gears three 25 connected to the four-bar linkage mechanism rotate synchronously, and further ensure that the four groups of hooks 4-1 driven by the driving units can move synchronously when the handle 2 is rotated.

[0059] In the present invention, the handle 2, the connecting rods one 23 and the connecting rods two 24 together form a four-bar linkage mechanism that rotates around the connecting long shaft 22 as a driving source, making the transmission of the tool sensitive, the driving source structure simple, and the transmission process stable and reliable.

[0060] Furthermore, the driving component one includes a mounting disc 3. The mounting disc 3 is slidably connected to the mounting column 4. A pin hole one 4-4 is provided on the side wall of the mounting column 4. A spring pin two 3-1 capable of inserting into the pin hole one 4-4 is provided on the side wall of the mounting disc 3. The mounting disc 3 is in transmission connection with a reciprocating component, and the reciprocating component is used to control the reciprocating sliding of the mounting disc 3; both ends of the shaft one 9 are respectively fixedly connected with a gear one 7 and a rotating plate 6. A pin one 4-2 is fixedly connected to the outer wall of the mounting column 4. A bracket 5 is fixedly connected with a pin two 5-1. A spring one is externally connected between the pin one 4-2 and the pin two 5-1. The spring one makes the mounting column 4 have a tendency to rotate counterclockwise; the bracket 5 is rotatably connected with a shaft two 29. The shaft two 29 is respectively fixedly connected with a gear four 30 and a gear five 31. The gear four 30 meshes with the gear one 7, and the gear five 31 meshes with the gear three 25;

[0061] In the initial state, under the elastic force of the spring one, the mounting column 4 always has a tendency to rotate counterclockwise relative to the bracket 5, making the pin one 4-2 on the mounting column 4 remain in the state at the left end of the arc groove 5-2, and further making the hook 4-1 remain in the retracted state;

[0062] The specific working process of the docking stroke described above in this embodiment is as follows: the handle 2 drives the gear three 25 to rotate counterclockwise, the gear three 25 drives the gear one 7 to rotate counterclockwise through the gear four 30 and the gear five 31, and the gear one 7 drives the mounting plate 3 to rotate counterclockwise. When the handle 2 reaches position b, the reciprocating assembly approaches the position c with the handle 2, and controls the mounting plate 3 to gradually mount the column 4 (in the initial state, the maximum protruding length of the spring pin two 3-1 is less than the distance between the mounting plate 3 and the mounting column 4), until the handle 2 reaches position c, the mounting plate 3 is close to the side wall of the mounting column 4, and correspondingly, at this time, the spring pin two 3-1 is aligned with the pin hole one 4-4, and under the action of its own elastic force, the spring pin two 3-1 is inserted into the pin hole one 4-4 on the side wall of the mounting column 4, so that the mounting plate 3 is locked with the mounting column 4 (in the process of the handle 2 moving from position b to position c, before the spring pin two 3-1 is aligned with the pin hole one 4-4, the spring pin two 3-1 is squeezed by the mounting column 4 and retracted into the mounting plate 3 to avoid the position);

[0063] Then, pull the handle 2 to the right to position a (handle 2 rotates clockwise), and the corresponding gear 1 7 rotates clockwise;

[0064] Rotation stroke: the reciprocating assembly controls the mounting plate 3 to move away from the mounting column 4 until the spring pin 2 3-1 is completely separated from the pin hole 1 4-4. At the same time, during this process, the gear 1 7 drives the mounting plate 3 to rotate clockwise (during this process, the spring pin 2 3-1 is not completely separated from the pin hole 1 4-4), so that the spring pin 2 3-1 drives the mounting column 4 to rotate clockwise through the engagement with the pin hole 1 4-4, so that the grab hook 4-1 rotates clockwise with the mounting column 4 to overcome the elastic force of the spring 1 to a vertical state, so that the spring pin 1 4-3 on the mounting column 4 rotates clockwise to the pin hole 2 5-2-1 and is inserted;

[0065] Lifting stroke: At this time, the spring pin 2 3-1 has completely disengaged from the pin hole 1 4-4, and the grab hook 4-1 remains in a vertical state.

[0066] By transmission through gear four 30 and gear five 31, the transmission ratio from gear three 25 to gear one 7 is changed, thereby reducing the limited rotation range of handle 2, resulting in restrictions on tool parameter design due to the limited rotation range of gear three 25.

[0067] Further, the driving component 2 includes a mounting cavity 4-5 provided in the mounting column 4, the grab hook 4-1 is arranged on one side of the mounting cavity 4-5, and a gear 2 4-6 is arranged on the other side of the mounting cavity 4-5, the shaft 19 can drive the gear 2 4-6 to rotate, the handle of the grab hook 4-1 is provided with teeth, and the gear 2 4-6 can mesh with the teeth; the gear 2 4-6 is connected to the transmission with a synchronization mechanism, and the synchronization mechanism can drive the gear 2 4-6 to move longitudinally and mesh with the grab hook 4-1 when the mounting plate 3 moves longitudinally, and make the shaft 19 and the gear 2 4-6 engage; the reset component can make the gear 2 4-6 disengage from the meshing with the grab hook 4-1.

[0068] The handle 2 rotates from a to c to the state as shown in Figure 15 After that, the handle 2 rotates to b to the state as shown in Figure 16 During the process, as the synchronization mechanism moves longitudinally closer to the mounting post 4 along with the mounting disc 3, the synchronization mechanism controls the longitudinal movement of the second gear 4-6 to engage with the hook 4-1, and makes the first shaft 9 and the second gear 4-6 engage; then the handle 2 rotates to c to the state as shown in Figure 17 During the process, the first gear 7 drives the first shaft 9 to rotate clockwise, and further the first shaft 9 drives the second gear 4-6 to rotate clockwise, so that the second gear 4-6 drives the hook 4-1 to move vertically upward; and the floor grille is vertically lifted by the cylindrical cross beam of the floor grille, completing the disassembly of the floor grille.

[0069] When temporarily placing the floor grille, since the floor grille needs to be reinstalled later, most of the floor grilles are stacked indoors. And because the composition materials of the indoor floor are different, there are many materials similar to marble that are fragile or easily damaged; this leads to the need to consider protecting the floor during the placement process of the floor grille.

[0070] Furthermore, an installation frame 8 is fixedly connected to the side wall of the mounting post 4. An airbag 8-1 is arranged in the installation frame 8. The lower end of the airbag 8-1 is fixedly connected to the base of the installation frame 8. A one-way valve for air intake is fixedly connected to the lower end of the airbag 8-1. A connecting piece 8-2 is fixedly connected to the upper end of the airbag 8-1. The connecting piece 8-2 is connected to the hook 4-1. An air hole is opened at the upper end of the airbag 8-1.

[0071] It should be noted that the air intake speed of the one-way valve is much greater than the air ventilation speed of the air hole; when the hook 4-1 moves upward, the upper end of the airbag 8-1 is lifted upward. At this time, the airbag 8-1 intakes air through the air hole and the one-way valve, causing the airbag 8-1 to expand; when the hook 4-1 moves upward to place the floor grille, the hook 4-1 squeezes the upper end of the airbag 8-1 downward. At this time, the airbag 8-1 exhausts air through the air hole, enabling itself to be compressed. Since the exhaust speed of the air hole is limited, the airbag 8-1 cannot be quickly compressed. Furthermore, the airbag 8-1 plays a good buffering role in the downward movement of the hook 4-1. Furthermore, the airbag 8-1 plays a good buffering role in the falling of the floor grille, avoiding damage to the bearing position caused by the impact during the falling process of the floor grille.

[0072] When it is not necessary to consider protecting the bearing position during the placement process of the floor grille, the existence of the airbag 8-1 undoubtedly reduces the work efficiency.

[0073] Furthermore, the connecting piece 8-2 is provided with a slot, and the hook 4-1 is slidably connected with a plug 8-4 that can be inserted into the slot.

[0074] According to the actual application scenario, when the bearing position of the local grille needs to be protected, the block 8-4 is slid to insert the block 8-4 into the slot, so that the grab hook 4-1 engages with the connecting piece 8-2, and the airbag 8-1 is used for cushioning during the falling process of the grab hook 4-1; when the bearing position of the local grille does not need to be protected, the block 8-4 is slid to disengage the block 8-4 from the slot, so that the grab hook 4-1 disengages from the connecting piece 8-2, and the airbag 8-1 is invalidated, thereby improving the working efficiency of the tool.

[0075] Furthermore, the synchronization mechanism includes a bearing 10, which is rotatably connected to the end of the mounting plate 3, and a bearing 11 is provided at one end of the gear 2 4-6 near the mounting plate 3, and a spring 12 is fixedly connected between the bearing 10 and the bearing 2 11; a locking groove 13 is provided on the inner wall of the gear 2 4-6, and a clamping block 14 is fixedly connected to the overlapping section of the side wall of the shaft 9 and the grab hook 4-1, and the clamping block 14 is used to engage with the locking groove 13.

[0076] When the mounting plate 3 approaches the mounting column 4, the mounting plate 3 drives the bearing 10 to move toward the mounting column 4. Then, the bearing 10 pushes the bearing 11 and the gear 4-6 toward the grab hook 4-1 through the spring 12, and makes the gear 4-6 mesh with the grab hook 4-1, and makes the shaft 19 and the gear 4-6 engage. Furthermore, when the mounting plate 3 moves away from the mounting column 4, the bearing 10 drives the bearing 11 away from the side wall of the gear 4-6 through the spring 12, and the gear 4-6 still keeps meshing with the grab hook 4-1.

[0077] Furthermore, a guide block 15 matching the outer wall contour of gear 2 4-6 is provided on the inner wall of the installation cavity 4-5 at the placement position of gear 2 4-6, and gear 2 4-6 is engaged with the guide block 15. A guide angle 15-1 is provided on the side of the guide block 15 close to the grab hook 4-1, and the guide angle 15-1 is used to assist gear 2 4-6 to engage with the guide block 15 again; the distance between the guide block 15 and the grab hook 4-1 is greater than the thickness of gear 2 4-6.

[0078] The projection of the toothed profile of the inner wall of the guide block 15 at the grab hook 4-1 meshes with the grab hook 4-1, so that the gear 2 4-6 pushed out from the guide block 15 can mesh with the grab hook 4-1 smoothly; further, through the guide angle 15-1, the reset process of the gear 2 4-6 returning to the guide block 15 can be carried out smoothly, so that the tool can be used repeatedly and the gear 2 4-6 can be kept meshing with the grab hook 4-1 smoothly.

[0079] Furthermore, the reciprocating assembly includes an annular groove 16 provided on the side wall of the mounting plate 3, an arch block 17 longitudinally slidably connected to the connecting long axis 22 is provided on one side of the handle 2, the upper circular surface of the arch block 17 is coaxial with the connecting long axis 22, a threaded groove 18 is provided on the upper end of the arch block 17, and the spiral trajectory of the threaded groove 18 is coaxial with the connecting long axis 22, a connecting rod 21 is fixedly connected to the side wall of the handle 2, a slide bar 19 is fixedly connected to the lower end of the connecting rod 21, a slide bar 20 is fixedly connected to the side wall of the arch block 17, and the slide bar 20 is slidably connected to the annular groove 16; the slide bar 19 can enter the threaded groove 18 as the handle 2 rotates, and the slide bar 19 entering the threaded groove 18 can squeeze the arch block 17 and drive the arch block 17 to move longitudinally.

[0080] When the handle 2 moves to position b, the corresponding slide bar 19 moves to the opening of the thread groove 18, and then in the process of the handle 2 moving from position b to position c, the slide bar 19 moves from the opening of the thread groove 18 to the deep part of the thread groove 18, and in this process, by squeezing the inner wall of the arch block 17, the arch block 17 moves longitudinally towards the mounting column 4. Further, the arch block 17 drives the slide bar 20 to move longitudinally, and the slide bar 20 drives the mounting plate 3 to move toward the mounting column 4. Correspondingly, in the process of the handle 2 moving from position c to position b, the slide bar 19 moves from the deep part of the thread groove 18 to the opening of the thread groove 18, so that the arch block 17 drives the mounting plate 3 to move away from the mounting column 4.

[0081] Furthermore, the reset assembly includes a slot 33 transversely opened on the side wall of the spring pin 4-3, and the outer wall of the mounting column 4 is slidably connected with a slide bar 34 and a slide bar 4 35 respectively. The end of the slide bar 34 passes through the outer wall of the mounting column 4 and is slidably connected with the slot 33, and the end of the slide bar 4 35 passes through the outer wall of the mounting column 4 and extends into the mounting cavity 4-5. The slide bar 34 and the slide bar 4 35 are commonly fixedly connected with an arc plate 36 elastically slidably connected to the outer wall of the mounting column 4, and the end of the arc plate 36 is rotatably connected with an annular plate 37 mounted on the outer wall of the mounting column 4. A hand brake device 38 is provided on the handle 2, and the hand brake device 38 is connected to the annular plate 37 through an external transmission element. The hand brake device 38 is used to pull the annular plate 37 toward the mounting disk 3 assembly direction; the slide bar 34 and the slide bar 4 35 can respectively pull the spring pin 4-3 and the gear 2 4-6 toward the mounting disk 3 assembly direction.

[0082] The vehicle body 1 transfers the ground grille to the temporary storage position. When the ground grille drops, the handbrake device 38 is pulled. The handbrake device 38 pulls the annular plate 37 towards the mounting plate 3 assembly through the transmission element, and then moves the third slide bar 34 and the fourth slide bar 35 towards the mounting plate 3 assembly, causing the first spring pin 4-3 and the second gear 4-6 to move towards the mounting plate 3 assembly. Further, the first spring pin 4-3 disengages from the arc groove 5-2, and the mounting column 4 can rotate relative to the bracket 5 under the elastic force of the first spring, causing the grab hook 4-1 to become inclined and in the retracted state. The second gear 4-6 disengages from the grab hook 4-1 and re-enters the guide block 15. Correspondingly, without the support of the second gear 4-6, the grab hook 4-1 moves downward under the action of gravity. At this time, under the action of gravity, the grab hook 4-1 moves downward, allowing the ground grille to descend to the bearing position. Then the grab hook 4-1 continues to move downward, causing the grab hook 4-1 to disengage from the cylindrical cross beam of the ground grille. At the same time, under the elastic force of the first spring, the mounting column 4 rotates counterclockwise and drives the grab hook 4-1 to rotate counterclockwise and reset to the retracted state.

[0083] Further, the left end of the vehicle body 1 is fixedly connected with a vertically arranged L-shaped plate 32. The width of the L-shaped plate 32 is greater than the grille width of the ground grille. The support wheels 26 are symmetrically arranged in the front and rear on the right side of the lower end of the vehicle body 1. A bracket 27 is vertically and fixedly connected to the upper end of the vehicle body 1 on the right side of the handle 2. The bracket 27 is used to limit the right rotation limit of the handle 2.

[0084] By using the first slide bar 19 to cooperate with the thread groove 18 to limit the left rotation limit of the handle 2 and using the bracket 27 to limit the right rotation limit of the handle 2, the tool can enable the operator to clearly identify positions a and c through its own structure, thereby reducing the operation difficulty of the tool.
