[0002] A moving vehicle is an automated mechanical device used to transport furniture and other goods to high places. It usually uses a retractable ladder and a trolley to carry out transportation operations.

[0003] For example, a Chinese patent discloses an aerial work vehicle (CN211004450U) that is linked to a winch, which includes a vehicle body with a folding lifting device; the folding lifting device includes a mechanical bucket trolley and a ladder; the front end and the end of the ladder are respectively provided with a transverse pulley A and a transverse pulley B; the ladder is provided with a ladder wire rope, one end of the ladder wire rope is passed around the transverse pulley A and is fixedly connected to the ladder winch; the front end of the ladder is also provided with a pulley; the mechanical bucket trolley is provided with a mechanical bucket trolley wire rope, one end of the mechanical bucket trolley wire rope is passed around the pulley and is fixedly connected to the mechanical bucket trolley winch; the trolley winch hydraulic motor and the ladder hydraulic motor are both connected to the hydraulic multi-way valve.

[0004] The shortcomings of the above-mentioned prior art are:

[0005] When working, the aerial ladder is first extended to lean against the window sill or balcony edge of the high floor, and then the trolley is controlled to start operation; during the operation, the aerial ladder will bend and deform to a certain extent due to the pressure of the trolley and the influence of the back-and-forth transportation movement, causing the upper end of the aerial ladder to swing up and down. At this time, the aerial ladder and the window sill or balcony will move relative to each other and damage the window sill or balcony structure; this friction phenomenon will also affect the structure of the aerial ladder and pose a safety hazard. Summary of the Invention

[0006] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a wall guard frame assembly for a moving vehicle.

[0007] The present invention adopts the following technical solution: a wall guard frame assembly of a moving vehicle, including a base with an "L"-shaped cross-section, which is buckled on the edge of the floor; rollers are fixed on the upper side of the base, and when working, the ladder is pressed on the rollers; an adjustment plate is hinged on the lower side of the base, and the adjustment plate is in contact with the outer side of the floor.

[0008] Preferably, the base is bent and formed, and comprises a horizontal plate and a vertical plate; the adjustment plate is hinged to the lower side of the vertical plate, an adjustment bolt is installed on the vertical plate, and the inner end of the adjustment bolt abuts against the adjustment plate.

[0009] Preferably, a positioning nut is installed on the adjusting bolt.

[0010] Preferably, a pair of ear plates are connected to both ends of the base, and one roller is installed on each pair of ear plates.

[0011] Preferably, a right-angle groove is provided at the bottom of the ear plate, and the right-angle groove of the ear plate is welded and fixed to the horizontal plate and the vertical plate of the base respectively.

[0012] Preferably, the lug plate on the inner side of the roller is lower than the roller, and the lug plate on the outer side of the roller is higher than the roller.

[0013] Preferably, the outer ear panel is connected with a zipper.

[0014] The beneficial effects of the present invention are: the base is fixedly installed on the edge of the floor by a zipper, and the ladder is pressed on the rollers on the base. During operation, the ladder and the rollers slide relative to each other, avoiding damage to the window sill or balcony structure of the floor, and greatly reducing the friction on the upper end of the ladder; the angle of the adjustment plate on the inner side of the base can be adjusted by adjusting the bolts, which is convenient for fitting with the side of the floor at different angles, improving the stability of the base, and preventing the base from sliding during operation, which affects the transportation operation of the trolley on the ladder.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Combine Figures 1 to 5 As shown, a wall guard frame assembly for a moving vehicle. The base 1 has an "L"-shaped cross-section, and the base 1 includes a horizontal plate 101 and a vertical plate 102, and the whole is formed by bending. The adjustment plate 3 is located on the inner side of the vertical plate 102, and the adjustment plate 3 is hingedly connected to the lower end of the vertical plate 102. A row of adjustment bolts 4 are installed on the vertical plate 102, and the inner ends of the adjustment bolts 4 are against the adjustment plate 3. The adjustment bolts 4 are installed with positioning nuts 401. During operation, the base 1 is buckled on the edge of the floor 7, and the adjustment plate 3 is in contact with the outer edge of the floor 7; the angle of the adjustment plate 3 is adjusted by adjusting the bolts 4 to ensure that the adjustment plate 3 can be in contact with the outer edge of the floor 7 at different angles. After adjustment, the adjustment bolts 4 are positioned by the positioning nuts 401.

[0024] A pair of ear plates 5 are connected to each end of the base 1. The bottom of the ear plates 5 is provided with a right-angled groove. The right-angled grooves of the ear plates 5 are welded and fixed to the horizontal plate 101 and the vertical plate 102 of the base 1. A roller 2 is rotatably mounted on each pair of ear plates 5. The ear plates 5 have an inclined angle with the horizontal plate 101 and the vertical plate 102, which improves the overall strength of the base 1. When the rollers 2 are under pressure, the ear plates 5 can disperse the pressure to the horizontal plate 101 and the vertical plate 102, making the support structure more stable. During operation, the two sides of the ladder 8 press on the rollers 2 on both sides. The ear plates 5 on the inner side of the roller 2 are lower than the roller 2, and the ear plates 5 on the outer side of the roller 2 are higher than the roller 2. This can limit the left and right swing of the ladder 8 and improve its stability during transportation. The outer ear plates 5 are connected to a zipper 6. When in use, the base 1 is fixed by connecting a counterweight to the zipper 6 or connecting the zipper 6 indoors.

[0025] Working principle: Combination Figure 1 and Figure 5As shown, the base 1 is fixedly installed on the side of the floor 7 by a zipper 6. After the ladder 8 is extended, it presses on the roller 2 on the base 1, controlling the trolley on the ladder 8 to start working. During the operation, the ladder 8 will bend and deform to a certain extent due to the pressure of the trolley and the impact of the back-and-forth transportation movement, causing the upper end of the ladder 8 to shake up and down. At this time, the upper end of the ladder 8 slides relative to the roller 2 to offset the force, avoiding damage to the window sill or balcony structure of the floor by the ladder 8, and greatly reducing the friction on the upper end of the ladder 8. According to the different structures of the floor 7, the angle of the adjustment plate 3 on the inside of the base 1 can be adjusted by adjusting the bolt 4, so as to facilitate the fit with the side of the floor 7 at different angles, improve the stability of the base 1, and prevent the base from sliding during operation, which affects the transportation operation of the trolley on the ladder 8.
