[0030] The specific settings and functions of the adjusting device 2 and the extending device 3 are described in detail below.
[0031] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjusting device 2 includes a sliding block 21, the sliding block 21 is slidably connected to the inner surfaces of the sliding grooves of the two car bodies 1, the upper surface of the sliding block 21 is fixedly connected to a ladder 22, the side of the sliding block 21 close to the ladder 22 is fixedly connected to two fixing rods 23, the arc surface of the fixing rod 23 is slidably connected to an operating plate 24, the side of the operating plate 24 close to the sliding block 21 is fixedly connected to a plug plate 25, the inner surface of the car body 1 is provided with a plurality of slots, and the end of the fixing rod 23 away from the sliding block 21 is fixedly connected The limit plate 26 is connected, and the size of the plug plate 25 is adapted to the size of the slot of the car body 1. When the staff pulls the operating plate 24, the operating plate 24 slides on the arc surface of the fixed rod 23. At this time, the limit plate 26 achieves the effect of limiting the maximum sliding distance of the operating plate 24 on the fixed rod 23, avoiding the situation that the operating plate 24 is separated from the arc surface of the fixed rod 23 due to excessive pulling force when the staff pulls the operating plate 24. The arc surface of the fixed rod 23 is sleeved with a first spring 27, and the two ends of the first spring 27 are respectively The first spring 27 is fixedly connected to the operating plate 24 and the sliding block 21. When the operator releases the operating plate 24, the resilience of the first spring 27 drives the operating plate 24 to slide on the arc surface of the fixed rod 23. At the same time, the operating plate 24 drives the plug plate 25 to move until the plug plate 25 is inserted into the slot of the car body 1. At this time, the first spring 27 improves the stability of the plug plate 25 when limiting the sliding block 21. The side of the sliding block 21 close to the fixed rod 23 is fixedly connected with two screws 28. The arc surface of the screw 28 is threadedly connected with an L-shaped plate 29. When the operator releases the operating plate 24, the first spring 27 drives the plug plate 25 to move until the plug plate 25 is inserted into the slot of the car body 1. At this time, the first spring 27 improves the stability of the plug plate 25 when limiting the sliding block 21. Two screws 28 are fixedly connected to the side of the sliding block 21 close to the fixed rod 23. The arc surface of the screw 28 is threadedly connected with an L-shaped plate 29. After the operator pulls the operating panel 24 to the highest point of the fixed rod 23, the operator rotates the L-shaped plate 29 so that the L-shaped plate 29 is threadedly rotated on the arc surface of the screw rod 28 until the L-shaped plate 29 moves to just below the operating panel 24. At this time, the L-shaped plate 29 has the effect of limiting the movement of the operating panel 24, thereby preventing the operator from sliding the sliding block 21 due to vibration, causing the operating panel 24 to slide on the arc surface of the fixed rod 23, causing friction between the plug plate 25 and the car body 1, thereby affecting the operator's operation of the device.
[0032] Reference Figure 4 and Figure 5As shown, specifically, the extension device 3 includes two L-shaped frames 33, and the two L-shaped frames 33 are fixedly connected to the two sides of the straight ladder 22 respectively. Two strip plates 31 are slidably inserted in the straight ladder 22, and the two strip plates 31 are fixedly connected to the pedal 32 on the side close to each other. A driving rod 34 is inserted into the internal thread of the L-shaped frame 33, and one end of the driving rod 34 is rotatably connected to a connecting plate 35. A connecting groove is provided on the surface of the strip plate 31, and a handle 36 is fixedly connected to the end of the driving rod 34 away from the connecting plate 35. When the staff rotates the driving rod 34, the driving rod 34 can be driven to move in the internal thread of the L-shaped frame 33 by rotating the handle 36. At this time, the handle 36 achieves the effect of facilitating the operation of the staff, so as to improve the staff's For the convenience of device operation, a positioning rod 37 is fixedly connected to the side of the connecting plate 35 close to the driving rod 34, and the arc surface of the positioning rod 37 is slidably connected to the L-shaped frame 33. When the staff turns the handle 36, the handle 36 drives the driving rod 34 to rotate on the internal thread of the L-shaped frame 33. At the same time, the driving rod 34 drives the connecting plate 35 to move, and the connecting plate 35 drives the positioning rod 37 to slide in the L-shaped frame 33. At this time, the positioning rod 37 has the effect of limiting the connection plate 35 from following the rotation of the driving rod 34, thereby avoiding the connection plate 35 following the rotation of the driving rod 34 when the staff turns the driving rod 34, which makes it difficult for the connection plate 35 to be accurately inserted into the connecting groove of the strip plate 31, thereby increasing the workload of the staff.
[0033] Working principle: when the staff needs to adjust the position of the vertical ladder 22, they pull the operating plate 24 to make the operating plate 24 slide on the fixed rod 23, the first spring 27 is stretched, and the operating plate 24 drives the plug plate 25 to move until the plug plate 25 is disengaged from the slot of the car body 1. At this time, the L-shaped plate 29 is rotated to make the L-shaped plate 29 threadedly rotate on the arc surface of the screw rod 28 until the L-shaped plate 29 moves to the bottom of the operating plate 24. At this time, the vertical ladder 22 is pulled, and the vertical ladder 22 drives the sliding block 21 to slide in the sliding groove of the car body 1. After reaching a suitable height, the operating plate 24 is released. The operating plate 24 is operated, and the rebound force of the first spring 27 drives the operating plate 24 to slide on the arc surface of the fixing rod 23. At the same time, the operating plate 24 drives the plug plate 25 to move until the plug plate 25 is inserted into the slot of the car body 1. At this time, the effect of adjusting the position of the straight ladder 22 is achieved, which avoids the situation that when the staff needs to use the straight ladder 22, the position of the straight ladder 22 is too close to the inner wall of the car body 1, which makes it difficult for the staff to use a vertical angle to pass through the safety window on the top of the car body 1, thereby making it inconvenient for the staff to use the straight ladder 22 to quickly escape, thereby improving the practicability of the device.
[0034] When the staff needs to extend the straight ladder 22, they pull the pedal 32, which drives the strip plate 31 to slide in the straight ladder 22 until the strip plate 31 is extended to the highest point. At this time, the handle 36 is turned, and the handle 36 drives the driving rod 34 to move in the inner thread of the L-shaped frame 33. At the same time, the driving rod 34 drives the connecting plate 35 to move, and the connecting plate 35 drives the positioning rod 37 to slide in the L-shaped frame 33 until the connecting plate 35 is inserted into the connecting groove of the strip plate 31. At this time, the effect of extending the climbable height of the straight ladder 22 is achieved, which avoids the situation that some of the staff members are short in height, resulting in the height of the straight ladder 22 being difficult for the staff to quickly escape, causing the situation that affects the staff's escape speed, thereby improving the practicability of the device.
