[0009] In a preferred embodiment of the present invention, it further includes guide wheels symmetrically distributed along the support frame, the guide wheels are fixedly connected to the adjacent support frame, and the steel wire is fixedly connected to the adjacent tool box after passing around the adjacent guide wheels.

[0010] In a preferred embodiment of the present invention, it also includes fixing rods symmetrically distributed along the support frame, the fixing rods are fixedly connected to the adjacent support frames, and a clamping frame is slidably connected between the fixing rods on the same longitudinal side. The clamping frame is provided with two upper and lower triangular protrusions on one side close to the adjacent electric push rod. The electric push rod slides up and down along the support frame, and the triangular protrusions are used to limit the adjacent electric push rods.

[0011] In a preferred embodiment of the present invention, a first spring is further included, wherein the first spring is fixed between the fixing rod and the adjacent supporting frame.

[0012] In a preferred embodiment of the present invention, it also includes guide rods symmetrically distributed along the scaffolding boards, the guide rods are slidably connected to the adjacent support frames, the scaffolding boards contact the adjacent guide rods during the swinging process, the brackets are provided with oblique grooves corresponding to the guide rods, and the guide rods are slidably connected to the oblique grooves adjacent to the brackets.

[0013] In a preferred embodiment of the present invention, a second spring is further included, and the second spring is fixed between the base of the electric push rod and the adjacent support frame.

[0014] In a preferred embodiment of the present invention, it also includes a support plate symmetrically distributed along the scaffolding board, the support plate is rotatably connected to the adjacent support frame, the support plate is fixed with a boss, the side of the scaffolding board away from the adjacent boss is fixed with a pressure frame, the support plate is used to support the pressure frame, the side of the scaffolding board close to the adjacent boss is fixed with triangular blocks symmetrically distributed along the scaffolding board, the end face of the triangular block close to the adjacent boss is set as an inclined surface, the triangular block is squeezed and matched with the adjacent boss through the inclined surface, and a torsion spring is fixed between the support plate and the adjacent support frame.

[0015] In a preferred embodiment of the present invention, it also includes a card block symmetrically distributed along the tool box, the card block is slidably connected to the adjacent tool box, the support frame has card slots symmetrically distributed along the support frame, the card block is squeezed and matched with the adjacent card slot, and a third spring is fixed between the card block and the adjacent tool box.

[0016] The present invention has the following advantages: the present invention controls the scaffolding boards on the upper and lower sides to swing ninety degrees inward and downward by arranging an electric push rod, so that maintenance personnel can select scaffolding boards of corresponding height as the working height according to the adaptability of the maintenance height of the mechanical arm, without the need for frequent adjustments, and the operation is simple and convenient.

[0017] Compared with the electric push rods provided on both the upper and lower sides for independently controlling the scaffolding boards on each side, the present invention only provides the electric push rod on the lower side and the guide groove of the guide plate. This scheme can lock the scaffolding board on the other side while controlling the scaffolding board on one side to open, thereby improving the safety of maintenance operations and preventing the scaffolding board on the other side from being accidentally opened and colliding with the mechanical arm during maintenance operations.

[0018] The present invention adopts a non-fixed arrangement that the tool box can be moved up and down, so that when the tool box is lowered to the ground, the maintenance tools are placed in the tool box, and then the tool box is slid upward along the support frame to between the upper and lower scaffolding boards, so that the maintenance tools can be placed more easily.

[0019] When the gear rotates, the present invention synchronously controls the tool box to move downward close to the scaffolding board on the opened side, so that the maintenance personnel can take the maintenance tools in the tool box at a close distance when standing on the scaffolding board on the opened side to perform maintenance on the maintenance position of the mechanical arm at a corresponding height, and the tool box can also serve as a guardrail on the outer side of the corresponding height.

[0020] The present invention changes the electric push rod into a sliding setting, so that the electric push rod is limited and fixed by the triangular protrusion before and during use, so that the scaffolding board can be normally extended and retracted to control the flipping of the scaffolding board. After the electric push rod is used, the limit on the electric push rod is released, so that when the electric push rod generates a push-pull force due to erroneous operation, the electric push rod can unload the force to the second spring, thereby avoiding the situation where the scaffolding board is reset or the electric push rod is damaged by stress.

[0021] When the scaffolding board swings inward and downward, the supporting plate automatically rotates to be supported on the bottom of the pressure frame, thereby improving the stability of the scaffolding board support and thus improving the safety of the maintenance work.

[0022] During the descending process, the tool box of the present invention descends slowly due to the intermittent squeezing and cooperation of the clamping slot and the clamping block, thereby preventing the tool box from being broken due to excessive descending speed.

DETAILED DESCRIPTION

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Embodiment 1: A workshop arch trolley maintenance workbench, such as Figures 1-3As shown, it includes a workbench base 1, the top of the workbench base 1 is fixedly connected to a support frame 2 symmetrically distributed along the left and right sides of the workbench base 1, and ladders that can be climbed up and down are fixedly arranged on the front and rear sides of the support frame 2. An upper and lower scaffolding board 3 is rotatably connected between the front and rear sides of the support frame 2, and an electric push rod 4 symmetrically distributed along the front and rear sides of the support frame 2 is provided at the lower part of the support frame 2. The upper and lower parts of the support frame 2 are slidably connected to guide plates 5 symmetrically distributed along the front and rear sides of the scaffolding board 3, and the telescopic rod of the electric push rod 4 is fixedly connected to the adjacent lower guide plate 5, and the guide plate 5 is provided with a guide groove, and the upper side of the guide groove of the guide plate 5 is set to be vertical The straight portion is arranged on the lower side as an oblique portion inclined inwardly, the guide groove of the guide plate 5 is movably connected with the adjacent scaffolding board 3, the oblique portion of the guide groove of the guide plate 5 is used to push the scaffolding board 3 on one side to rotate, and at the same time, the straight portion of the guide groove of the guide plate 5 is used to lock the scaffolding board 3 on the other side, the opposite end faces of the adjacent scaffolding boards 3 are fixedly connected with racks 6, the middle part of the supporting frame 2 is rotatably connected with gears 7 symmetrically distributed along the front and rear of the supporting frame 2, the racks 6 are meshed with the adjacent gears 7, and a tool box 8 for holding maintenance tools is provided on the outer side of the workbench base 1, and the tool box 8 is located between the upper and lower scaffolding boards 3 on the same side.

[0036] First, drive the arch frame trolley to be repaired to the front or rear side of the workbench base 1, so that the mechanical arm of the arch frame trolley is supported in the middle of the workbench base 1. If the part of the mechanical arm of the arch frame trolley to be repaired is in a low position, the electric push rod 4 is controlled to extend, thereby driving the lower guide plate 5 to move upward, and the lower guide plate 5 squeezes the lower scaffolding board 3 through the oblique part of the guide groove to swing ninety degrees downward and inward, so that the maintenance personnel can stand on the lower scaffolding board 3 to inspect the left and right sides of the low position of the mechanical arm. At the same time, under the transmission action of the rack 6 and the gear 7, the upper guide plate 5 moves downward, so that the straight part of the guide groove of the upper guide plate 5 locks the upper scaffolding board 3. After the maintenance is completed, the electric push rod 4 is controlled to retract and reset, so that the scaffolding board 3 is retracted, so that the arch frame trolley has sufficient operating space to move the mechanical arm away.

[0037] If the part of the mechanical arm of the arch trolley to be inspected is in a high position, the electric push rod 4 is controlled to shorten, thereby driving the lower guide plate 5 to move downward. Under the transmission action of the rack 6 and the gear 7, the upper guide plate 5 moves upward, and the upper guide plate 5 squeezes the upper scaffolding board 3 through the oblique part of the guide groove and swings ninety degrees toward the inner and lower sides, which is convenient for maintenance personnel to stand on the upper scaffolding board 3 to inspect the left and right sides of the high position of the mechanical arm. At the same time, the straight part of the guide groove of the lower guide plate 5 locks the lower scaffolding board 3. After maintenance, the electric push rod 4 is controlled to extend and reset, so that the scaffolding board 3 is retracted, which is convenient for the arch trolley to have sufficient operating space to move the mechanical arm away.

[0038] In summary, by setting the electric push rod 4, the scaffold boards 3 on the upper and lower sides are controlled to swing downward by ninety degrees towards the inside, enabling maintenance personnel to adaptively select the scaffold board 3 at the corresponding height as the working height according to the maintenance height of the robotic arm, without frequent adjustment, and the operation is simple and convenient.

[0039] Moreover, by only setting the electric push rod 4 on the lower side and through the guiding groove of the guiding plate 5, compared with setting electric push rods 4 for independently controlling each side of the scaffold board 3 on both the upper and lower sides, in this solution, when one side of the scaffold board 3 is controlled to open, the other side of the scaffold board 3 can be locked simultaneously, improving the safety of maintenance operations and preventing the scaffold board 3 on the other side from accidentally opening and hitting the robotic arm during maintenance operations.

[0040] Embodiment 2: On the basis of Embodiment 1, as Figure 4 and Figure 5 shown, it further includes a screw rod 10 corresponding to the gear 7. The screw rod 10 is fixedly connected to the corresponding gear 7. A wire reel 11 is inserted into the screw rod 10. A steel wire 9 is wound around the wire reel 11. The end of the screw rod 10 is threadedly connected with a nut 12 for fastening the wire reel 11. The tool box 8 can slide up and down along the support frame 2. The upper part of the support frame 2 is fixedly connected with wire guiding wheels 13 symmetrically distributed in the front and back along the support frame 2. The steel wire 9 bypasses the adjacent wire guiding wheels 13 and is fixedly connected to the adjacent tool box 8.

[0041] Since maintenance tools are usually relatively heavy, it is laborious and unsafe to pick up and place them into the tool box 8 through the ladder. Therefore, the tool box 8 is changed to a non-fixed setting that can move up and down. The specific operation is as follows: Loosen the nut 12, slide the wire reel 11 outwards along the screw rod 10 to disassemble it, so that the tool box 8 can be lowered along the support frame 2. When the tool box 8 reaches the ground, put the maintenance tools into the tool box 8, then slide the tool box 8 upwards along the support frame 2 again to between the upper and lower scaffold boards 3, and then reinstall the wire reel 11 on the screw rod 10 and tighten the nut 12 to fix the tool box 8. In this way, the placement of maintenance tools can be completed more easily.

[0042] When the gear 7 rotates, it drives the wire reel 11 to rotate in the same direction. When the electric push rod 4 extends, the gear 7 rotates counterclockwise to drive the wire reel 11 to rotate counterclockwise, and the wire reel 11 gradually releases the steel wire 9, causing the tool box 8 to move downward and approach the lower scaffold board 3. In this way, when the maintenance personnel stand on the lower scaffold board 3 to perform maintenance on the lower part of the robotic arm, they can pick up the maintenance tools in the tool box 8 at a close distance, and the tool box 8 can also act as a guardrail on the outside at the lower position.

[0043] When the electric push rod 4 is shortened, the gear 7 rotates clockwise to drive the wire drum 11 to rotate clockwise, and the wire drum 11 gradually reels the steel wire 9. The steel wire 9 pulls the tool box 8 upward to the upper scaffolding board 3. In this way, when the maintenance personnel stand on the upper scaffolding board 3 to inspect the high position of the robot arm, they can also take the maintenance tools in the tool box 8 at a close distance, and the tool box 8 can also act as a guardrail on the outside of the high position.

[0044] Embodiment 3: Based on embodiment 2, Figure 6 and Figure 7 As shown, it also includes a fixed rod 14 symmetrically distributed along the front and back of the support frame 2, the fixed rod 14 is fixedly connected to the lower part of the adjacent support frame 2, and a bracket 15 is slidably connected between the upper and lower fixed rods 14 on the same side along the front and back direction, and two upper and lower triangular protrusions 151 are arranged on the lower side of the bracket 15, and the electric push rod 4 slides up and down along the support frame 2, and the triangular protrusions 151 are used to limit the adjacent electric push rods 4 up and down, and a first spring 16 is fixedly connected between the fixed rod 14 and the adjacent support frame 2, and the support frame 2 is slidably connected along the up and down direction with a guide rod 17 symmetrically distributed along the front and back of the scaffolding board 3, and the scaffolding board 3 contacts the corresponding guide rod 17 during the swinging process, and the bracket 15 is provided with an oblique groove corresponding to the guide rod 17, and the guide rod 17 is slidably connected to the oblique groove adjacent to the bracket 15, and a second spring 18 is fixedly connected between the base of the electric push rod 4 and the adjacent support frame 2.

[0045] If the electric push rod 4 is fixed, when the maintenance personnel stand on the scaffolding board 3 for maintenance, if other staff members mistakenly operate the electric push rod 4, the push-pull force generated by the electric push rod 4 may cause the scaffolding board 3 to be reset or the electric push rod 4 to be damaged by stress, which is very dangerous. Therefore, the electric push rod 4 is changed to a sliding setting, so that the electric push rod 4 is limited and fixed by the triangular protrusion 151 in the early stage and during use, so that the scaffolding board 3 can be normally extended and controlled to flip. After the use of the electric push rod 4 is completed, the limit of the electric push rod 4 is released, so that when the electric push rod 4 generates a push-pull force due to misoperation, the electric push rod 4 can unload the force to the second spring 18. The specific implementation method is as follows: When the scaffolding board 3 on either side swings ninety degrees inward and downward, the scaffolding board 3 will contact the guide rod 17 on the same side during the swinging process, and squeeze the guide rod 17 to move downward, and the guide rod 17 squeezes the bracket 15 through the inclined groove to slide to the side of the adjacent first spring 16, and the bracket 15 drives the triangular protrusion 151 to move in the same direction until it is disengaged from the base of the electric push rod 4, thereby releasing the limit on the electric push rod 4. Afterwards, if the electric push rod 4 is accidentally touched, the push and pull force generated by the extension and contraction of the electric push rod 4 directly acts on the second spring 18, and the second spring 18 is adaptively stretched or compressed, and subsequent maintenance personnel will stand on the scaffolding board 3. Under the action of the human body's own gravity, the scaffolding board 3 will press the guide rod 17 to resist the elastic force of the first spring 16 to prevent the first spring 16 from resetting during maintenance.

[0046] Embodiment 4: Based on embodiment 3, Figure 8 and Figure 9 As shown, it also includes a support plate 19 symmetrically distributed along the front and back of the scaffolding board 3, the support plate 19 is rotatably connected to the adjacent supporting frame 2, a boss 191 is fixed to the top of the support plate 19, a pressure frame 192 is fixed to the side of the scaffolding board 3 away from the adjacent boss 191, the support plate 19 is used to support the pressure frame 192, and a triangular block 20 symmetrically distributed along the front and back of the scaffolding board 3 is fixed to the side of the scaffolding board 3 close to the adjacent boss 191, the end face of the triangular block 20 close to the adjacent boss 191 is set as an inclined surface, the triangular block 20 is squeezed and matched with the adjacent boss 191 through the inclined surface, and a torsion spring 21 is fixed between the support plate 19 and the adjacent supporting frame 2.

[0047] When the scaffolding board 3 swings inward and downward, the scaffolding board 3 drives the triangular block 20 to rotate. When the triangular block 20 rotates to disengage from the boss 191, the torsion spring 21 in the force storage state resets and drives the support plate 19 to rotate to the bottom of the pressure frame 192, thereby improving the stability of the support of the scaffolding board 3 and thus improving the safety of the maintenance work. When the scaffolding board 3 swings in the opposite direction to the bottom of the retracted support frame 2, the scaffolding board 3 is squeezed by the inclined surface of the triangular block 20 to swing in the opposite direction to the bottom of the retracted support frame 2, and the torsion spring 21 is twisted and deformed.

[0048] Embodiment 5: Based on embodiment 4, Figure 9 and Figure 10 As shown, it also includes a card block 22 symmetrically distributed along the front and back of the tool box 8, the card block 22 is slidably connected to the adjacent tool box 8, the support frame 2 is provided with a card slot 221 symmetrically distributed along the front and back of the support frame 2, the card slot 221 is set to be serrated, the card block 22 is squeezed and matched with the adjacent card slot 221, and a third spring 23 is fixed between the card block 22 and the adjacent tool box 8.

[0049] During the process of the tool box 8 descending along the support frame 2 under the action of gravity, if the descending speed is too fast, the tool box 8 will be damaged. Therefore, it is necessary to slow down the descending speed of the tool box 8. Specifically: during the descending process of the tool box 8, the clamping block 22 and the third spring 23 are driven to descend synchronously. Under the intermittent extrusion cooperation between the card slot 221 and the clamping block 22, the third spring 23 is intermittently compressed and reset, so as to achieve the effect of the tool box 8 descending at a slow speed.
