[0027] At the same time, by starting the limiting mechanism 7, the upper surface of the limiting mechanism 7 is abutted against the lower surface of the supporting mechanism 6, so that the limiting mechanism 7 supports the rear lower end of the supporting mechanism 6, thereby avoiding as much as possible the rear side of the supporting mechanism 6 from tilting toward the lower end during use, thereby improving the stability of the front and rear sides of the supporting mechanism 6 during use.

[0028] like Figures 1 to 4 As shown, the support mechanism 6 includes an L-shaped connecting plate 605, a bolt 607 and a second supporting plate 608. The L-shaped connecting plate 605 is installed on the front of a group of supporting platforms 5 on the left side by means of the bolt 607. A block 606 is slidably connected inside the L-shaped connecting plate 605. A groove is provided on one side of the group of supporting platforms 5 on the left side close to the other group of supporting platforms 5. The position of the groove inside the group of supporting platforms 5 on the left side is located on the moving path of the block 606. The second supporting plate 608 is installed on the side of the block 606 away from the L-shaped connecting plate 605. Two groups of guardrails 604 are arranged on the upper surface of the second supporting plate 608. An L-shaped fixing plate 601 is installed on the back of the L-shaped connecting plate 605. An electric telescopic rod 602 is arranged on the inner side wall of the L-shaped fixing plate 601. A connecting plate 603 is installed on the output end of the electric telescopic rod 602. The connecting plate 603 is installed on the lower surface of the L-shaped connecting plate 605. The height of the upper surface of the second supporting plate 608 is balanced with the height of the upper surfaces of the two groups of supporting platforms 5.

[0029] Specifically, the two groups of sliders 3 are driven to move the two groups of support platforms 5 to both sides by starting the bidirectional electric telescopic rod 12, and the support plate 2 608 is driven to move by starting the electric telescopic rod 602, and the block 606 is inserted into the groove of the left support platform 5, and the positions of the two groups of support platforms 5 are reset by starting the bidirectional electric telescopic rod 12, and the adjacent sides of the two groups of support platforms 5 are respectively connected to the left and right sides of the support plate 2 608, so that the support plate 2 608 expands the support area of ​​the device, thereby facilitating the use of the staff.

[0030] At the same time, by keeping the upper surface of the second support plate 608 and the upper surface of the two groups of support platforms 5 in parallel, the staff is not easily tripped by the support mechanism 6 when walking on the two groups of support platforms 5 and the upper end of the second support plate 608, thereby improving the safety of the support mechanism 6 during use; the support mechanism 6 is installed on the front of the left support platform 5 by the bolt 607, so that the staff can remove the support mechanism 6 from the front of the left group of support platforms 5 during the process of turning the bolt 607, thereby facilitating the subsequent staff to regularly replace and maintain the support mechanism 6, and reducing the cost of replacement and maintenance of the subsequent support mechanism 6 after damage, thereby improving the practicality of the device.

[0031] like Figure 2 As shown, a limiting block 8 is installed on the side of the other group of support platforms 5 close to the support mechanism 6, and a groove is opened on the side of the support plate 2 608 away from the left support platform 5, and the positions of the internal groove of the support plate 2 608 and the internal groove of the left group of support platforms 5 are both located in parallel with the limiting block 8; specifically, when the block 606 is slidably connected to the inside of the groove of the left group of support platforms 5, the positions of the two groups of support platforms 5 are reset by starting the two-way electric telescopic rod 12, and the limiting block 8 is inserted into the inside of the groove of the support plate 2 608, so that the limiting block 8 supports the side of the support plate 2 608 close to the other group of support platforms 5, and then the limiting block 8 supports the right side of the support plate 2 608, thereby minimizing the tilting of the support plate 2 608 to the right during use, thereby improving the safety of the support mechanism 6 during use.

[0032] At the same time, when the device is idle, the two sets of slide blocks 3 are driven to move by starting the bidirectional electric telescopic rod 12, and the limit block 8 is clamped into the groove of the left set of support platforms 5, so that the limit block 8 supports the connection between the two sets of support platforms 5, thereby minimizing the inclination of the two sets of support platforms 5 toward the adjacent side of the two sets of support platforms 5 when the staff steps on the connection between the two sets of support platforms 5, thereby improving the stability of the connection between the two sets of support platforms 5.

[0033] like Figure 1 and Figure 2As shown, the limiting mechanism 7 includes an L-shaped limiting plate 701, which is installed on the lower surface of a group of supporting platforms 5 on the left side. A hydraulic cylinder 702 is installed at the bottom of the inner wall of the L-shaped limiting plate 701, and a positioning plate 703 is installed at the output end of the hydraulic cylinder 702. The position of the positioning plate 703 is located at the lower end of the second supporting plate 608; specifically, when the second supporting plate 608 is installed between the two groups of supporting platforms 5, the positioning plate 703 is pushed to move by starting the second hydraulic cylinder 702, so that the upper surface of the positioning plate 703 is abutted against the lower end of the rear side of 708, so that the positioning plate 703 supports the lower end of the rear side of the second supporting plate 608, and then the L-shaped connecting plate 605 and the positioning plate 703 respectively support the lower ends of the front and rear sides of the second supporting plate 608, so as to avoid the rear side of the second supporting plate 608 from tilting toward the lower end during use, thereby improving the stability of the front and rear sides of the second supporting plate 608 during use.

[0034] like Figure 2 As shown, the upper surfaces of the two groups of support platforms 5 and the second support plate 608 are provided with anti-skid grooves 9; specifically, the anti-skid grooves 9 increase the friction of the staff standing on the upper ends of the two groups of support platforms 5 and the second support plate 608, making it difficult for the staff to slip when standing on the upper ends of the two groups of support platforms 5 and the second support plate 608, thereby improving the safety of the staff when standing on the upper end of the device to work, thereby improving the practicality of the device.

[0035] like Figures 1 to 4 As shown, an electric control box 10 is provided on the inner wall of one side of the left group of support platforms 5 away from the support mechanism 6, and the electric control box 10 is electrically connected to the control ends of the hydraulic cylinder 1 4, the electric telescopic rod 602, the hydraulic cylinder 2 702 and the bidirectional electric telescopic rod 12; specifically, by operating the electric control box 10 to start the internal mechanical equipment of the device, the staff does not need to run back and forth when operating the device to expand and contract, thereby reducing the labor consumed by the staff when operating the device; the electric control box 10 is arranged on the side of the left group of support platforms 5 away from the support mechanism 6, so that the staff does not need to come into close contact with the empty space between the two groups of support platforms 5 when operating the support mechanism 6 to splice between the two groups of support platforms 5, thereby improving the safety of the staff when operating the device.

[0036] In summary: by starting the two-way electric telescopic rod 12, the two groups of sliders 3 are driven to pull the two groups of support platforms 5 to move to both sides, and then by starting the electric telescopic rod 602, the support plate 2 608 is driven to move, the block 606 is inserted into the groove of the left support platform 5, and the position of the two groups of support platforms 5 is reset by starting the two-way electric telescopic rod 12, and the adjacent sides of the two groups of support platforms 5 are respectively abutted against the left and right sides of the support plate 2 608, so that the support plate 2 608 expands the support area of ​​the device, thereby facilitating the use of the staff; the support mechanism 6 is installed on the front side of the left support platform 5 by the bolt 607, so that the staff can disassemble the support mechanism 6 from the front side of the left group of support platforms 5 during the process of turning the bolt 607, thereby facilitating the subsequent staff to regularly replace and maintain the support mechanism 6, and reducing the cost of replacement and maintenance of the subsequent support mechanism 6 after damage.

[0037] At the same time, by starting the two-way electric telescopic rod 12 to reset the positions of the two groups of support platforms 5, the limit block 8 is inserted into the groove of the second support plate 608, so that the limit block 8 supports the side of the second support plate 608 close to the other group of support platforms 5, and then the limit block 8 supports the right side of the second support plate 608, thereby minimizing the support plate 608 from tilting to the right during use; by starting the two-way electric telescopic rod 12 to drive the two groups of sliders 3 to pull the two groups of support platforms 5 to move, the limit block 8 is clamped into the groove of the left group of support platforms 5, so that the limit block 8 supports the connection between the two groups of support platforms 5, thereby minimizing the two groups of support platforms 5 from tilting to the side adjacent to the two groups of support platforms 5 when the staff steps on the connection between the two groups of support platforms 5.

[0038] In addition, by starting the hydraulic cylinder 2 702 to push the positioning plate 703 to move, the upper surface of the positioning plate 703 is abutted against the lower end of the rear side of 708, so that the positioning plate 703 supports the lower end of the rear side of the support plate 2 608, and then the L-shaped connecting plate 605 and the positioning plate 703 respectively support the lower ends of the front and rear sides of the support plate 2 608, thereby minimizing the tilting of the rear side of the support plate 2 608 toward the lower end during use.
