Detailed implementation manner

[0023] See Figures 1-6 , the present invention provides a technical solution: an adjustable working ladder placement device for an electric power construction vehicle, including two groups of positioning plates 1 and reinforcing telescopic rods 2. The two groups of positioning plates 1 are distributed in parallel correspondingly. Both ends of the reinforcing telescopic rod 2 are locked and fixed to the side walls of the positioning plates 1. Adjusting assemblies 3 are installed on the outer walls of the positioning plates 1, and a reinforcing assembly 4 is assembled on the adjusting assemblies 3.

[0024] Locking plates 5 are symmetrically installed at the tops of the positioning plates 1, and mounting holes are penetrated through the locking plates 5.

[0025] The adjusting assembly 3 includes an adjusting cross plate 6, a sliding frame 7, a limiting slide rail 8, two built-in cavities 9 and two transmission parts 10. The adjusting cross plate 6 is welded to the middle of the outer wall of the positioning plate 1. The limiting slide rail 8 is opened in the middle of the outer wall of the adjusting cross plate 6. The sliding frame 7 is slidably sleeved outside the adjusting cross plate 6 and is slidably engaged with the limiting slide rail 8. The built-in cavities 9 are opened at the tops and bottoms of the adjusting cross plate 6. The transmission parts 10 are installed at the tops and bottoms of the side walls of the sliding frame 7. The sliding frame 7 drives the reinforcing assembly 4 to slide left and right on the adjusting cross plate 6, and the distance between the two reinforcing assemblies 4 can be adjusted, further increasing the adaptation range of the device, enabling it to adapt to ladders of multiple specifications for limiting use, and allowing fine adjustment by the staff.

[0026] The transmission part 10 includes a transmission rack 11, a mounting frame 12, a micro motor 13 and a driving gear 14. The transmission rack 11 is locked and installed at the bottom end of the built-in cavity 9. The mounting frame 12 is locked and installed at the top and bottom ends of the side wall of the sliding frame 7. The driving gear 14 is rotatably installed on the mounting frame 12. The micro motor 13 is installed on the side wall of the mounting frame 12 through a bracket, and the output end of the micro motor 13 is in transmission connection with the driving gear 14. The driving gear 14 is in meshing transmission connection with the transmission rack 11. Starting the micro motor 13 drives the driving gear 14 to rotate. By using the meshing transmission between the driving gear 14 and the transmission rack 11, power is provided for the movement of the sliding frame 7.

[0027] The reinforcement assembly 4 includes an extension plate 15, two baffle plates 16, a middle rail 17, two linkage blocks 18, two extension threaded rods 19 and two reinforcement members 20. The extension plate 15 is locked and installed on the side wall of the sliding frame 7. The baffle plates 16 are symmetrically locked and installed on both sides of the upper surface of the extension plate 15. The middle rail 17 is opened in the middle of the outer wall of the extension plate 15. The linkage blocks 18 are symmetrically slidably installed on the side wall of the extension plate 15 and are correspondingly engaged with the middle rail 17. The extension threaded rods 19 are screwed through the baffle plates 16 and are rotatably connected to the side walls of the linkage blocks 18. The reinforcement members 20 are locked and installed on the side walls of the linkage blocks 18, and the working directions of the two reinforcement members 20 on the extension plate 15 are opposite. First, the ladder is initially engaged with the reinforcement member 20 at the top of the extension plate 15. Then, the bottom extension threaded rod 19 is rotated. Under the limitation of the baffle plate 16, the reinforcement member 20 at the bottom of the extension plate 15 follows the middle rail 17 and moves upward, so that the reinforcement member 20 at the bottom of the extension plate 15 is correspondingly engaged with the lower part of the ladder, realizing double fixed limit for the ladder, and facilitating dynamic adjustment and installation for ladders of different sizes.

[0028] The reinforcement member 20 is integrally in an L-shaped structure, and an anti-slip pad is installed on the inner wall of the reinforcement member 20.

[0029] A reinforcing plate 21 is slidably installed in the reinforcement member 20, and a positioning spring 22 is installed between the reinforcing plate 21 and the reinforcement member 20. By installing the reinforcing plate 21 in the reinforcement member 20 and making the reinforcing plate 21 slide in the reinforcement member 20 under the push of the positioning spring 22, the ladder inside the reinforcement member 20 can be reinforced and limited, avoiding the situation of accidental sliding of the ladder subsequently.

[0030] In use, first, the two sets of positioning plates 1 are preliminarily fixed to the vehicle body by using the locking plate 5. Since the reinforcing telescopic rod 2 is installed between the two sets of positioning plates 1, the distance between the two sets of positioning plates 1 and the reinforcing component 4 can be adjusted by using the reinforcing telescopic rod 2, the overall positioning range can be expanded, different specifications of ladders can be effectively matched for limit fixation, which is convenient for the staff to operate. By providing the reinforcing component 4, the ladder is first preliminarily engaged with the reinforcing member 20 at the top of the extension plate 15, and then the bottom extension threaded rod 19 is rotated. Under the limit of the baffle 16, the reinforcing member 20 at the bottom of the extension plate 15 is driven to move upward along the middle slide rail 17, so that the reinforcing member 20 at the bottom of the extension plate 15 is correspondingly engaged with the lower part of the ladder, realizing the double fixation and limit of the ladder, and it is convenient to adapt to ladders of different sizes for dynamic adjustment and installation. By installing the reinforcing plate 21 in the reinforcing member 20 and making the reinforcing plate 21 slide in the reinforcing member 20 under the push of the positioning spring 22, the ladder inside the reinforcing member 20 can be reinforced and limited, avoiding the accidental sliding of the ladder subsequently, and strengthening the stability of the ladder installation. By providing the adjusting component 3, the sliding frame 7 drives the reinforcing component 4 to slide left and right on the adjusting cross plate 6, and the distance between the two sets of reinforcing components 4 can be adjusted, further increasing the adaptation range of the device, enabling it to adapt to multi-specification ladders for limit use, which can be finely adjusted by the staff. And with the cooperation of the transmission part 10, the micro motor 13 is started to drive the driving gear 14 to rotate. By using the meshing transmission of the driving gear 14 and the transmission rack 11, power is provided for the movement of the sliding frame 7, which is convenient for the staff to adjust and use.
