Description

Technical Field:

[0001] The utility model relates to the technical field of transportation, and particularly relates to an automatic car leveling device. Background Art:

[0002] When a coal hauling truck is loading coal, non-automatic loading results in uneven filling at the top of the hopper. In this case, coal hauling will cause coal to spill everywhere, which is extremely unfriendly to the environment and other moving vehicles; when the filling is extremely uneven before and after, there may be uneven center of gravity, and there is a possibility of tipping over. Manual leveling of coal requires a large amount of labor. Content of the Utility Model:

[0003] The purpose of the utility model is to provide an automatic car leveling device.

[0004] The utility model is implemented by the following technical solutions:

[0005] An automatic car leveling device includes a base, a vertical plate, a hydraulic cylinder, a pushing flat plate, a tarpaulin, an arch frame, and a sliding rope. Two hydraulic cylinders are fixedly arranged side by side at the top of the base. A vertical plate is arranged between the fixed ends of the two hydraulic cylinders. The bottom of the vertical plate is fixed to the base. A pushing flat plate is fixed between the telescopic ends of the two hydraulic cylinders;

[0006] A number of arch frames are arranged between the pushing flat plate and the vertical plate. The arch frames straddle above the two hydraulic cylinders. The sliding rope is arranged on both sides of the top of the hopper. The two ends of the arch frame are slidably connected to the sliding rope. The tarpaulin covers the tops of a number of arch frames and is fixed to the arch frames. One end of the tarpaulin is fixed to the vertical plate, and the other end of the tarpaulin is fixed to the top of the pushing flat plate.

[0007] Preferably, the hydraulic cylinder is a multi-stage telescopic hydraulic cylinder.

[0008] Preferably, the bottom of the pushing flat plate is in the shape of a rake.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Embodiment:

[0019] As Figures 1-4 shown, an automatic flatbed device includes a base 1, a vertical plate 3, a hydraulic cylinder 2, a push flat plate 4, a tarpaulin 7, an arched frame 5, and a sliding rope 6. Two hydraulic cylinders 2 are fixedly arranged side by side on the top of the base 1. The hydraulic cylinder 2 is a multi-stage telescopic hydraulic cylinder. A vertical plate 3 is arranged between the fixed ends of the two hydraulic cylinders 2. The bottom of the vertical plate 3 is fixed to the base 1. A push flat plate 4 is fixed between the telescopic ends of the two hydraulic cylinders 2. The bottom of the push flat plate 4 is in the shape of a rake.

[0020] The utility model is installed at the end of the carriage above the cab, which is defined as the front end of the carriage. Conversely, the other end of the carriage is the rear end of the carriage. The base 1 is fixed to the front end of the carriage. The vertical plate 3 is located away from the front end of the carriage. The bottom of the pushing flat plate 4 is placed in the carriage from the top of the carriage. By sequentially extending the telescopic ends of the two hydraulic cylinders 2, the pushing flat plate 4 is driven from the front end of the carriage to the rear end of the carriage to level the top of the coal material. The rake shape at the bottom of the pushing flat plate 4 helps to reduce resistance and makes the pushing smoother.

[0021] In this embodiment, the hydraulic cylinder 2 can be selected from any one of the three to five-stage telescopic hydraulic cylinders, and the stroke of the telescopic end only needs to meet the length of the carriage. Since the more telescopic ends of the multi-stage telescopic hydraulic cylinder, the larger its volume. Therefore, when selecting, for example, if the self-unloading truck has a small load capacity and a small carriage size, a three-stage telescopic hydraulic cylinder can be selected; if the self-unloading truck has a large load capacity and a large carriage size, a five-stage telescopic hydraulic cylinder can be selected. The power supply part of the hydraulic cylinder 2 is realized through the oil pump and oil tank fixed to the carriage, and the oil pipes connecting the hydraulic cylinder 2, the oil pump, and the oil tank.

[0022] A number of arched frames 5 are arranged between the pushing flat plate 4 and the vertical plate 3. The arched frames 5 straddle above the two hydraulic cylinders 2. The sliding ropes 6 are arranged on both sides of the top of the carriage. The sliding ropes 6 include a fixing plate 6.1, an L-shaped plate 6.2, and a steel wire rope 6.3. The fixing plate 6.1 is fixed to the side of the base 1, the L-shaped plate 6.2 is fixed to the end of the carriage, and both ends of the steel wire rope 6.3 are fixed to the fixing plate 6.1 and the L-shaped plate 6.2 respectively. Both ends of the arched frame 5 are slidably connected to the sliding rope 6. Sleeves sleeved on the steel wire rope 6.3 are fixed to both ends of the arched frame 5, and the sliding of the arched frame 5 on the sliding rope 6 is realized through the sleeves.

[0023] The tarpaulin 7 covers the tops of a number of arched frames 5 and is fixed to the arched frames 5. One end of the tarpaulin 7 is fixed to the vertical plate 3, and the other end of the tarpaulin 7 is fixed to the top of the pushing flat plate 4. When the telescopic end of the hydraulic cylinder 2 drives the pushing flat plate 4 to extend, one end of the tarpaulin 7 is pulled to move, and the stationary and folded tarpaulin 7 is pulled open. When the tarpaulin 7 moves, it is realized by the sliding of a number of arched frames 5 on the sliding rope 6. And the arched frames 5 support the tarpaulin 7 to avoid being clamped by the telescopic end of the hydraulic cylinder 2. While leveling the coal, the tarpaulin 7 is covered on the top of the carriage to avoid the scattering of coal material during transportation.

[0024] Working principle: When the utility model is in use, the base 1 is fixed to the front end of the carriage. The utility model is installed at the front end of the carriage and above the cab. The telescopic ends of the two hydraulic cylinders 2 are sequentially extended to drive the pushing flat plate 4 from the front end of the carriage to the rear end of the carriage to level the top of the coal material.

[0025] When the telescopic end of the hydraulic cylinder 2 drives the pushing flat plate 4 to extend, one end of the tarpaulin 7 is pulled to move, and the stationary and folded tarpaulin 7 is pulled open. When the tarpaulin 7 moves, a number of arched frames 5 slide on the sliding rope 6. While leveling the coal, the tarpaulin 7 is covered on the top of the carriage to avoid the scattering of coal material during transportation.

[0026] The telescopic end of the hydraulic cylinder 2 resets to drive the pushing plate 4 and the tarpaulin 7 to reset.

[0027] After loading coal, the coal is directly leveled by the pushing plate 4 installed in the truck bed of the present utility model, avoiding unevenness, reducing the probability of coal spilling everywhere during coal transportation. At the same time, the tarpaulin 7 can be covered on the top of the truck bed to enhance the function of preventing coal spillage; the top of the leveled coal material is relatively uniform, which can reduce the probability of tipping over due to uneven center of gravity. It replaces manual coal leveling and saves labor.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
