Figure 2 The diagram shown is a schematic representation of a drawer-type chassis for an engineering vehicle according to an embodiment of this utility model. Figure 1 and Figure 2 In this vehicle, the drawer-type frame includes at least two sliding rails 2, a drawer-type pedal 1, and a positioning device 3. Specifically, at least two sliding rails 2 are arranged parallel to each other on the bottom of the engineering vehicle, and a drawer-type pedal 1 is arranged between the two sliding rails 2. The drawer-type pedal 1 is connected to the two sliding rails 2, allowing the drawer-type pedal 1 to slide on the sliding rails 2. To prevent the drawer-type pedal 1 from sliding during use, a positioning device 3 is provided on the side of the sliding rail 2 away from the drawer-type pedal 1. This device is used to position the drawer-type pedal 1 on the sliding rail 2, thereby limiting the extension and retraction of the drawer-type pedal 1.

[0039] In this embodiment, to allow the drawer-type pedal 1 to slide along the sliding rail 2, multiple rollers 4 are provided on both sides of the drawer-type pedal 1 to drive it to slide along the sliding rail 2. A pin hole 5 is provided at the axis position of the roller 4 near the sliding rail 2. The positioning device 3 includes a pin 31, which engages with the pin hole 5 to position the drawer-type pedal 1 on the sliding rail 2. By providing multiple rollers 4, the pin 31 engages with the foremost roller 4 of the drawer-type pedal 1, allowing the drawer-type pedal 1 to be retracted and fixed to the bottom of the engineering vehicle. Pulling the pin 31 extends the drawer-type pedal 1, locking it at the middle roller 4. Pulling the pin 31 again inserts it into the pin hole 5 at the axis of the roller 4, locking the drawer-type pedal 1, achieving the first stage of extension. Pulling the pin 31 again allows the drawer-type pedal 1 to extend further, reaching the rear roller 4, where the pin 31 is inserted into the pin hole 5 at the axis of the roller 4, achieving the first stage of extension of the drawer-type pedal 1. Pulling out the latch 31 allows the drawer-type pedal 1 to be retracted. In this embodiment, the top of the drawer-type pedal 1 is provided with an anti-slip texture to prevent the operator from slipping during operation. Specifically, it can be as follows: Figures 3 to 7 As shown.

[0040] On the other hand, this utility model also provides an engineering vehicle, which includes an engineering vehicle body, at least two sliding rails 2, a drawer-type pedal 1, and a positioning device 3.

Specifically, at least two sliding rails 2 are arranged parallel to each other on the bottom of the engineering vehicle body, and a drawer-type pedal 1 is arranged between the two sliding rails 2. The drawer-type pedal 1 is connected to the two sliding rails 2, so that the drawer-type pedal 1 can slide on the sliding rails 2. In order to prevent the drawer-type pedal 1 from sliding during use, a positioning device 3 is provided on the side of the sliding rail 2 away from the drawer-type pedal 1. This device is used to position the drawer-type pedal 1 on the sliding rail 2 to limit the extension and retraction of the drawer-type pedal 1.

[0041] In this embodiment, to allow the drawer-type pedal 1 to slide along the sliding rail 2, multiple rollers 4 are provided on both sides of the drawer-type pedal 1 to drive it to slide along the sliding rail 2. A pin hole 5 is provided at the axis position of the roller 4 near the sliding rail 2. The positioning device 3 includes a pin 31, which engages with the pin hole 5 to position the drawer-type pedal 1 on the sliding rail 2. By providing multiple rollers 4, the pin 31 engages with the foremost roller 4 of the drawer-type pedal 1, allowing the drawer-type pedal 1 to be retracted and fixed to the bottom of the engineering vehicle. Pulling the pin 31 extends the drawer-type pedal 1, locking it at the middle roller 4. Pulling the pin 31 again inserts it into the pin hole 5 at the axis of the roller 4, locking the drawer-type pedal 1, achieving the first stage of extension. Pulling the pin 31 again allows the drawer-type pedal 1 to extend further, reaching the rear roller 4, where the pin 31 is inserted into the pin hole 5 at the axis of the roller 4, achieving the first stage of extension of the drawer-type pedal 1. Pulling out the latch 31 allows the drawer-type pedal 1 to be retracted. In this embodiment, the top of the drawer-type pedal 1 is provided with an anti-slip texture to prevent the operator from slipping during operation. Specifically, it can be as follows: Figures 3 to 7 As shown.

[0042] Through the above technical solution, this utility model relates to a drawer-type chassis for engineering vehicles and the engineering vehicle itself. The drawer-type chassis and engineering vehicle are constructed by parallelly arranging at least two sliding rails 2 on the engineering vehicle, with a drawer-type pedal 1 positioned between the two sliding rails 2, and the drawer-type pedal 1 slidably connected to the two sliding rails 2. A positioning device 3 is provided on the side of the sliding rails 2 away from the drawer-type pedal 1 to position the drawer-type pedal 1 on the sliding rails 2. This utility model connects the drawer-type pedal 1 via the sliding rails 2, allowing the drawer-type pedal 1 to extend and retract along the sliding rails 2. The structure is simple, easy to carry, and easy to store. The positioning device 3 enables the drawer-type pedal 1 to switch between different states, making it widely applicable to various engineering vehicles and facilitating the maintenance and repair of large engineering vehicles.
