DETAILED DESCRIPTION

[0016] In order to better understand the purpose, structure and function of the utility model, the auxiliary device for filling the back of the roadbed anti-collision wall of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, an auxiliary device for filling soil behind a roadbed crash wall comprises a box body 1, a supporting structure 2, a walking mechanism 3 and a connecting structure 4.

[0018] The box body 1 is in the shape of a square funnel as a whole and is made of 2.5 mm steel plate. It includes a material guide portion 11 with an upper opening that gradually narrows and a material discharge portion 12 that can extend into the middle of the anti-collision walls on both sides. A first reinforcing angle steel 13 is fixedly connected to the upper edge of the material guide portion 11, and a second reinforcing angle steel 14 is vertically connected to the first reinforcing angle steel 13 on each side plate of the material guide portion. Under the action of the first reinforcing angle steel 13 and the second reinforcing angle steel 14, the structural strength of the entire box body 1 can be guaranteed.

[0019] The support structure 2 uses two 4cm*4cm angle steels, which are respectively fixed on the left and right sides of the lower part of the material guide part 11. The front and rear sides of the support structures 2 on both sides are installed with the walking mechanism 3. The walking mechanism 3 includes a fixed rod 31 fixed on the upper end side of the support structure 2, and the two ends of the fixed rod 31 are fixedly connected to the vertical rod 32 extending downward, and an axle rod 33 is connected between the ends of the vertical rods 32 on both sides. The axle rod 33 is sleeved and connected with two walking rollers 34 that can be supported on the end surface of the anti-collision wall.

[0020] In this embodiment, the shaft rod 33 and the walking roller 34 are formed by a set of two steel pipes of different diameters, wherein the shaft rod 33 adopts a Φ50mm round steel pipe, and the walking roller 34 adopts a Φ89mm round steel pipe, and the walking roller 34 is driven by external traction to achieve walking.

[0021] The connection structure 4 is assembled and welded by 100mm*100mm square steel and channel steel, and includes a longitudinal rod 41 connected to the support structure 2. The longitudinal rod 41 is provided with a first diagonal rod 42 on the front and rear sides of the rod body near the box body 1 to connect the support structure 2, and a second diagonal rod 43 is provided on the upper side of the rod body to connect the box body 1. The longitudinal rod 41 of the connection structure 4 can be connected to a loader or a dump truck, so as to drive the entire device to move.

[0022] When in use, the device is placed on the crash barrier, and a small excavator is used to guide the soil into the box 1, so that the soil is filled in the middle of the crash barrier. The device itself does not need to install a power system and a vibration system. It can move under the drive of external traction, and the vibration generated during the walking on the top of the protective wall will vibrate the filling soil in the box 1 to fall, ensuring that the box 1 will not be blocked due to excessive filling soil. During the filling process, manual labor is used in conjunction with a hand-held vibration rammer to compact the filling soil layer by layer.
