Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a walking support device for pavers. Background Art

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. It can evenly lay materials such as crushed stone and asphalt concrete. Its main working principle is to transport concrete or asphalt materials from the hopper to the paving part through a series of mechanical devices and control systems, and then evenly lay the materials on the ground through vibration and compaction, and finally form a flat road surface or ground.

[0003] Pavers also play an important role in road repair. They can complete the paving work of large-area road pothole repairs in a short time, greatly saving labor and time, while improving construction efficiency and quality. However, in road repair, for narrower or smaller pothole repairs, small manually propelled pavers are usually used. These small pavers have a power system, and workers only need to grasp the direction when repairing flat sections; when repairing slope sections horizontally, small pavers need to move horizontally on the slope. While grasping the direction, workers also need to keep the small pavers balanced. Small pavers are tilted as a whole on the slope, and it is difficult for workers to push the pavers to move stably for a long time, which can easily lead to uneven asphalt paving, thereby affecting the quality of road pothole repairs and the normal use of the road in the later stage. To this end, we propose a walking support device for pavers. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a walking support device for a paver. The support plate can play a supporting role. When the staff hand-holds the small paver and moves it horizontally on the slope, it can avoid excessive tilting in the downhill direction and affecting the stable operation of the paver, share the pressure for the staff, avoid arm soreness during long-term operation and difficulty in steadily pushing the paver to move, make the asphalt paved evenly, ensure the repair quality of road potholes and the normal use of the road after repair, and can effectively solve the problems in the background technology.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the support device is connected to the small paver through the mounting plate, and the support device is arranged on one side or both sides of the paver. When repairing a flat road section or a wider pothole, the support device can be removed or adjusted to be horizontal by adjusting the angle of the rotating rod, so as not to affect the operation of the paver. When moving laterally on a slope section, the support plate can be made in contact with the ground at the downhill position by adjusting the angle of the rotating rod and the position of the sliding rod, and then the angle of the support plate can be adjusted to enable it to play a supporting role. When the staff moves the small paver laterally on the slope by hand, it can be avoided that the paver is excessively tilted in the downhill direction and affects the stable operation of the paver, the pressure is shared for the staff, and the arm pain of the staff during long-term operation makes it difficult to stably push the paver to move, so that the asphalt is evenly spread, and the repair quality of the potholes in the road and the normal use of the road after repair are guaranteed. The ball bearings arranged on the lower side of the support plate can replace the contact friction between the support plate and the road surface, thereby extending the service life of the device. At the same time, reducing friction can reduce the walking resistance of the paver, save electricity resources, and is beneficial to energy conservation and environmental protection.
