Description

Technical Field

[0001] This utility model relates to the field of fire truck auxiliary equipment technology, and in particular to a distributed electric drive emergency rescue fire truck with an emergency obstacle removal device. Background Technology

[0002] A search revealed that application number 202020690819.6 discloses an emergency obstacle removal device for a fire truck, comprising: a fire truck body; a fixed frame, the fixed frame being fixed to the front end of the fire truck body, the fixed frame having a sliding hole; at least two limiting slide shafts, the at least two limiting slide shafts being fixed inside the fixed frame; a first movable slide plate and a second movable slide plate, the first movable slide plate and the second movable slide plate both sliding on the surfaces of the two limiting slide shafts, the first movable slide plate having a first through hole, and the second movable slide plate having a second through hole.

[0003] In the application for an emergency obstacle removal device for a fire truck, a first hydraulic cylinder is used to extend and move a second movable sliding plate to the side of the vehicle. The second movable sliding plate, along with a linkage plate and an obstacle removal sliding plate thereon, pushes the obstacle away from the fire truck's safe passage, allowing the fire truck to pass quickly. However, in this process, the connection between the second movable sliding plate and the linkage plate forms an L-shaped structure, which is relatively weak. When the obstacle removal sliding plate pushes the obstacle, the connection between the second movable sliding plate and the linkage plate has to withstand the reaction force and torque, which can easily cause damage and reduce the service life of the device. Therefore, we propose a distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device, comprising a fire truck body, a fixed frame fixedly installed at the front end of the distributed electric-driven fire truck body, and two linkage plates disposed at the front end of the fixed frame. Obstacle removal sliding plate assemblies are symmetrically disposed at the front ends of the two linkage plates. A drive mechanism for moving the two linkage plates left and right is disposed inside the fixed frame. The drive mechanism includes two movable sliding plates slidably connected inside the fixed frame and two drive hydraulic telescopic cylinders fixedly connected to the left and right side walls of the inner cavity of the fixed frame. The front ends of the two movable sliding plates extend to the outside of the fixed frame and are fixedly connected to the ends of the two linkage plates that are close to each other. The telescopic end of each drive hydraulic telescopic cylinder is fixedly connected to the side wall of the movable sliding plate that is away from its position. A support mechanism is disposed on the two movable sliding plates. The support mechanism includes two limiting sliding columns fixedly connected to the rear ends of the two movable sliding plates. The ends of the two limiting sliding columns that are away from the two movable sliding plates extend through the left and right side walls of the inner cavity of the fixed frame to the outside. The ends of the two limiting sliding columns located outside the fixed frame are fixedly connected to two support connecting plates that are fixedly connected to the ends of the two linkage plates that are away from each other.

[0006] Furthermore, a sliding groove is provided through the front wall of the fixing frame.

[0007] Furthermore, the front ends of the two movable slide plates extend to the outside through the sliding groove.

[0008] Furthermore, the two drive hydraulic telescopic cylinders are arranged in an alternating position.

[0009] Furthermore, the sidewalls of the two movable sliding plates are provided with two clearance through holes corresponding to the positions of the two driving hydraulic telescopic cylinders, and one end of each of the two driving hydraulic telescopic cylinders passes through the interior of the two clearance through holes.

[0010] Furthermore, two limiting sliding holes are provided through the rear side of the left and right side walls of the inner cavity of the fixing frame, which correspond to and are adapted to the positions of the two limiting sliding pillars. The two limiting sliding pillars are slidably connected to the interior of the two limiting sliding holes on the fixing frame.

[0011] Furthermore, two connecting grooves are provided at the ends of the two linkage plates that are close to each other, and a connecting rod is provided between the two linkage plates.

[0012] Furthermore, the left and right ends of the connecting slide rod extend into the interior of the two connecting slide grooves and are fixedly connected with two limiting sliders that are slidably connected to the inner wall surfaces of the two connecting slide grooves.

[0013] This utility model provides a distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device. It has the following beneficial effects:

[0014] 1. This distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device, through the setting of a support mechanism, controls the extension end of the hydraulic telescopic cylinder to push the movable slide plate to the edge of the inner cavity of the fixed frame during use. The movable slide plate drives the linkage plate to move towards the side wall of the fire truck body. The linkage plate then drives the obstacle removal slide plate assembly to push the obstacle away from the side of the vehicle passage, so that the obstacle is removed from the front of the fire truck's safe passage, so that the fire truck can pass quickly. During this process, since the movable slide plate and the limiting slide column are slidably connected to the inside of the fixed frame, the linkage plate, together with the movable slide plate, the limiting slide column and the support connecting plate, forms a stable rectangular structure that is slidably connected to the fixed frame. This rectangular structure enhances the connection between the linkage plate and the fixed frame, improves the overall structural stability of the equipment, and extends the service life of the equipment.

[0015] 2. This distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device, by setting a connecting slide bar, the two ends of the connecting slide bar are slidably connected to the inside of two connecting slide grooves to form a limiting and guiding effect on the two linkage plates in the horizontal direction, so that the two linkage plates can move horizontally smoothly, further improving the stability of the overall structure of the equipment and improving the practicality of the equipment.

[0023] A distributed electric-driven emergency rescue fire truck with an emergency obstacle removal device, such as Figure 1-4 As shown, the fire truck includes a distributed electric drive fire truck body 10, a fixed frame 11 fixedly installed at the front end of the fire truck body 10, and two linkage plates 12 disposed at the front end of the fixed frame 11. The front ends of the two linkage plates 12 are symmetrically provided with obstacle-clearing sliding plate assemblies 13. The obstacle-clearing sliding plate assemblies 13 are existing technology and will not be described in detail. The fixed frame 11 is internally provided with a drive mechanism for moving the two linkage plates 12 left and right. The drive mechanism includes two movable sliding plates 14 slidably connected inside the fixed frame 11 and two drive hydraulic fluids fixedly connected to the left and right side walls of the inner cavity of the fixed frame 11. The telescopic cylinder 15 is pressed, and the front ends of the two movable slide plates 14 extend to the outside of the fixed frame 11 and are fixedly connected to the ends of the two linkage plates 12 that are close to each other. The front wall of the fixed frame 11 is provided with a sliding groove 17, and the front ends of the two movable slide plates 14 extend to the outside through the sliding groove 17. The telescopic end of each driving hydraulic telescopic cylinder 15 is fixedly connected to the side wall of the movable slide plate 14 that is far away from it. The two driving hydraulic telescopic cylinders 15 are arranged in an alternating position. The side walls of the two movable slide plates 14 are provided with a sliding groove 17 that is close to the rear wall of the two driving hydraulic telescopic cylinders 15. Two clearance holes 16 corresponding to position 5 are provided. One end of each of the two driving hydraulic telescopic cylinders 15 passes through the two clearance holes 16. Support mechanisms are provided on the two movable slide plates 14. The support mechanisms include two limiting slide pins 18 fixedly connected to the rear ends of the two movable slide plates 14. The ends of the two limiting slide pins 18 away from the two movable slide plates 14 extend to the outside through the left and right side walls of the inner cavity of the fixed frame 11. The ends of the two limiting slide pins 18 located outside the fixed frame 11 are fixedly connected to two supports that are fixedly connected to the ends of the two linkage plates 12 away from each other. The connecting plate 19 and the fixing frame 11 have two limiting sliding holes that correspond to and are adapted to the positions of the two limiting sliding posts 18 on the rear side of the left and right side walls of the inner cavity. The two limiting sliding posts 18 are slidably connected to the two limiting sliding holes on the fixing frame 11. Two connecting sliding grooves 20 are opened at the ends of the two linkage plates 12 that are close to each other. A connecting sliding rod 21 is provided between the two linkage plates 12. The left and right ends of the connecting sliding rod 21 extend into the two connecting sliding grooves 20 and are fixedly connected to two limiting sliding blocks 22 that are slidably connected to the inner wall of the two connecting sliding grooves 20.

[0024] The working principle of this utility model is as follows: In use, the telescopic end of the control-driven hydraulic telescopic cylinder 15 pushes the movable slide plate 14 to move towards the edge of the inner cavity of the fixed frame 11. The movable slide plate 14 drives the linkage plate 12 to move towards the side wall of the fire truck body 10. The linkage plate 12 then drives the obstacle removal slide plate assembly 13 to push the road obstacle to the side of the vehicle passage, so that the road obstacle is removed from the front of the fire truck's safety passage, so that the fire truck can pass quickly. During this process, because the movable slide plate 14 and the limiting slide post 18 are slidably connected to the inside of the fixed frame 11, the linkage plate 12 moves in coordination with the sliding plate 13. The sliding plate 14, the limiting sliding column 18, and the supporting connecting plate 19 form a stable rectangular structure that is slidably connected to the fixed frame 11. This rectangular structure enhances the connection between the linkage plate 12 and the fixed frame 11, improves the overall structural stability of the equipment, and extends the service life of the equipment. The two ends of the connecting sliding rod 21 are slidably connected to the inside of the two connecting sliding grooves 20 to form a limiting and guiding effect on the two linkage plates 12 in the horizontal direction, so that the two linkage plates 12 can move horizontally smoothly, further improving the overall structural stability of the equipment and enhancing the practicality of the equipment.
