Description

Technical Field

[0001] The utility model relates to the technical field of material handling, in particular to a material handling device for road and bridge construction. Background Art

[0002] Curbstones are strip-shaped objects made of stone or concrete and used as boundary stones at the edge of the road. Curbstones are also called curbstones or roadside stones. Curbstones are used to distinguish the roadway, sidewalk, green space, isolation zone and other parts of the road on the road surface, and they play a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edge. Therefore, curbstones have become one of the indispensable materials in road construction or bridge pavement construction.

[0003] During road construction, in order to ensure the regularity of the construction site, the curbstones are neatly stacked when they are transported to the site. Therefore, during the construction process, the curbstones need to be transported from the stacking site to the paving site. When the paving site is close to the curbstone stacking site, the construction workers usually use a two-person lifting and clamping method to transport the curbstones to the paving site. This method works well in a short time, but as time goes by, long-term manual operation can easily make the construction workers tired and reduce work efficiency. It may also cause fatigue and cause the curbstones to fall off the road surface, causing the curbstones to break. When the curbstones are continuously laid along the road surface, the stacking site of the curbstones is getting farther and farther from the required paving site. The construction workers usually use a curbstone transporter to transport them, but this type of transporter can usually only transport one curbstone at a time, which results in a lot of time wasted on the way back and forth, and the paving efficiency is low. In addition, during the transportation process, the curbstones along the road are always in a suspended state. When the road surface is uneven, there is a risk of falling off. Therefore, in view of the above problems, a material handling device for road and bridge construction is proposed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a U-shaped limit plate is provided on the top of the comb tooth end of the comb tooth plate. When the stacking point of the curbstones is too far away from the paving point of the curbstones, a certain number of curbstones are lifted to the comb tooth end of the comb tooth plate by a lifting mechanism, and then transported to the paving point. Compared with transporting one curbstone at a time, the handling efficiency is greatly improved and the paving speed is accelerated. The U-shaped limit plate is used on the one hand to reduce the situation that the curbstones fall to the ground due to the uneven road surface during transportation, and on the other hand to reduce the situation that the curbstones hit the hydraulic telescopic rod during the lifting process, thereby reducing losses and increasing the service life of the equipment.

[0014] 2. In the utility model, by lifting a certain number of curbstones onto the comb-tooth end of the comb-tooth plate, when the curbstone transporter transports the curbstones to the laying point, the construction workers can use tools with comb teeth, such as a hydraulic forklift, to quickly remove the curbstones, and then the construction workers lay them one by one, and the curbstone transporter can carry out the next round trip transportation, thereby reducing the waiting time for laying and increasing the transportation efficiency.

[0015] 3. In the utility model, a spring is connected to the top of the clamp block and the side wall of the J-shaped claw, so that when the clamp block clamps curbstones of different thicknesses, the side wall of the clamp block always fits tightly with the surface of the curbstone, reducing the possibility of falling off during the clamping process. A replaceable anti-slip rubber pad is installed on the side wall of the clamp block, which can increase the adsorption effect of the clamp block on the curbstone and reduce the possibility of damage to the curbstone during the clamping process.

[0024] The translation mechanism 6 includes an L-shaped beam 61 connected to the top axis of the telescopic end of the hydraulic telescopic rod 53, and the bottom end of the L-shaped beam 61 is connected to the top axis of the column 54. The two side walls of the L-shaped beam 61 are provided with through grooves 62 that penetrate the side walls, and the through grooves 62 are provided with sliders 63 that are slidably connected. By providing the through grooves 62 that penetrate the side walls on the two side walls of the L-shaped beam 61, the slider 63 can move back and forth along the L-shaped beam 61.

[0025] A fixedly connected iron chain 65 is provided at the bottom of the slider 63, and an electric telescopic rod 64 is provided on the left side wall of the L-shaped beam 61. The telescopic end of the electric telescopic rod 64 is fixedly connected to the slider 63. The slider 63 is driven to move back and forth by the telescopic movement of the electric telescopic rod 64, thereby realizing the lateral translation of the grabbing mechanism 7, providing a basis for subsequently placing the curbstone on the top of the comb tooth end.

The operation is repeated to place a certain number of curbstones on the top of the comb tooth end of the comb tooth plate 1, and then the curbstone transporter is pushed to transport the curbstones to the paving point. After arriving at the paving point, the construction workers can use tools with comb teeth, such as a hydraulic forklift, to remove the curbstones as a whole, and the curbstone transporter can carry out the next round trip transportation.
