Description

Technical Field

[0001] The invention relates to the technical field of municipal road construction, in particular to a self-unloading device for quickly unloading walkway bricks. Background Art

[0002] With the steady progress of China's modernization drive, the surface materials used for sidewalks in municipal road projects and plazas in construction projects have gradually been optimized from concrete to environmentally friendly materials such as paving bricks. The design standard axle loads for sidewalks and plazas are low, making it difficult for heavy-duty vehicles and forklifts to travel over the base material. After the materials arrive on-site, a forklift transports the entire package of paving bricks to the nearest construction site. During paving, the bricks are manually transported to the work area within the paving workers' reach. This secondary transport process requires manual operation, resulting in long, time-consuming and labor-intensive transport paths and extremely low labor efficiency. To address this situation, a self-unloading device for the rapid transport of paving bricks has been developed to improve work efficiency and save labor costs. Summary of the Invention

[0003] The present invention aims to solve the above problems and thus provides a self-unloading device for quickly unloading walkway bricks.

[0004] The present invention solves the above problems by adopting the following technical solutions:

[0005] A self-unloading device for quickly reversing walkway bricks includes an inclined frame, a storage base plate provided at the bottom end of the inclined frame, a storage support plate provided on the frame and above the storage base plate, the storage support plate being connected to an end of the storage base plate away from the frame, a plurality of strip holes formed on the storage support plate, a plurality of rolling shafts provided between the storage support plate and the storage base plate, storage wheels corresponding to the strip holes being sleeved on the rolling shafts, and the top ends of the storage wheels protruding from the strip holes, and a braking mechanism being provided on the rolling shafts.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0007] The present invention changes the traditional purely manual handling into semi-mechanized unloading. Workers only need to place batches of walkway bricks on the storage bracket, manually push them to the designated paving range, release the brake mechanism, and the walkway bricks can slide freely along the storage tray to achieve automatic unloading, which greatly reduces labor consumption, improves construction efficiency, reduces construction costs, and has very high economic benefits.

[0008] Preferably, a further technical solution of the present invention is:

[0009] The braking mechanism includes a braking gear that is clamped on the rolling shaft, a brake paddle is hinged on the bottom surface of the storage tray and above the brake gear, the bottom end of the brake paddle is clamped with the brake gear, a steel wire rope is connected to the brake paddle, a brake handbrake is provided at the end of the steel wire rope, the brake handbrake is fixed to the handle of the frame, a positioning wheel is slidably connected to the steel wire rope, and the positioning wheel is fixed to the bottom surface of the storage tray.

[0010] The storage wheel is connected to the rolling shaft by welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0016] See also Figure 1-Figure 3 A self-unloading device for quickly reversing walkway bricks includes a tilted vehicle 1, a storage base 2 being provided at the bottom end of the tilted vehicle frame 1, a storage support plate 3 being provided on the vehicle frame 1 and above the storage base 2, the storage support plate 3 being connected to an end of the storage base 2 away from the vehicle frame, a plurality of strip-shaped holes 4 being formed on the storage support plate 3, a plurality of rolling shafts 7 being provided between the storage support plate 3 and the storage base 2, storage wheels 5 corresponding to the strip-shaped holes 4 being sleeved on the rolling shafts 7, and the top ends of the storage wheels 5 protruding from the strip-shaped holes 4, and a braking mechanism 8 being provided on the rolling shafts 7.

[0017] The braking mechanism 8 includes a braking gear 8-3 that is clamped on the rolling shaft 7, and a brake paddle 8-2 is hingedly connected to the bottom surface of the storage tray 2 and above the braking gear 8-3. The bottom end of the brake paddle 8-2 is clamped with the brake gear 8-3, and a steel wire rope 8-1 is connected to the brake paddle 8-2. A brake handbrake 9 is provided at the end of the steel wire rope 8-1, and the brake handbrake 9 is fixed to the frame handle 6. A positioning wheel 8-4 is slidably connected to the steel wire rope 8-1, and the positioning wheel 8-4 is fixed to the bottom surface of the storage tray 2.

[0018] The storage wheel 5 is connected to the rolling shaft 7 by welding.

[0019] Bearing seats are provided on both sides of the bottom surface of the storage support plate, and the rolling shaft is movably connected to the storage support plate through the bearings.

[0020] During construction of this patent, the following steps are followed:

[0021] (1) Place the self-unloading device naturally on the side of the packed walkway bricks so that the storage base 2 is in contact with the natural ground, and check that the hand brake 9 is in the released state;

[0022] (2) The walkway bricks to be transported are naturally stacked on the upper surface of the storage tray 3. Since the storage wheels 5 are higher than the storage tray 3, the storage wheels 5 are actually in hard contact with the walkway bricks;

[0023] (3) Manually push the cart handle to move the cart into the paving area, and slowly lift the cart handle to make the storage base plate 2 fit into the natural ground;

[0024] (4) Press the hand brake 9, and transmit the torque through the brake strand 8-1, so that the brake paddle 8-2 rotates upward;

[0025] (5) The brake paddle 8-2 is separated from the brake gear 8-3, and the rolling shaft lacks the braking force to rotate;

[0026] (6) The walkway bricks slide down naturally and are automatically unloaded;

[0027] (7) Release the handbrake 9, the brake paddle 8-2 automatically returns to its original position under the action of gravity, locking the brake gear 8-3, and the trolley is in a braking state;

[0028] (8) Push the trolley to the side of the packed walkway bricks to quickly transport the next batch of walkway bricks.

[0029] The present invention changes the traditional purely manual handling into semi-mechanized unloading. Workers only need to place batches of walkway bricks on the storage bracket, manually push them to the designated paving range, and tighten the brake handbrake. The walkway bricks can slide freely along the storage tray and realize automatic unloading, which greatly reduces labor consumption, improves construction efficiency, reduces construction costs, and has very high economic benefits.
