TECHNICAL FIELD
[0001] The utility model belongs to road repair technical field, especially a kind of road maintenance crack pouring device. BACKGROUND
[0002] In the field of road traffic, with the growth of road service life and the comprehensive influence of vehicle load, natural environment and other factors, various cracks will inevitably appear on the road surface. If these cracks are not repaired in time, rainwater, sundries and other things will seep into the road base, causing damage to the base structure, and thus accelerating the destruction of the road, shortening the service life of the road and affecting driving safety and comfort. Therefore, road crack repair work is crucial to ensure road quality and maintain smooth traffic.
[0003] At present, the existing road crack repair equipment has some deficiencies in structure and function, and it is difficult to meet the efficient, convenient and high-quality road crack pouring operation requirements.
[0004] On the one hand, the overall structure of some traditional crack pouring equipment is relatively complex, bulky and heavy. In the construction site, such equipment is difficult to move, and needs to be transported and positioned with the help of special transport tools, which not only increases the construction cost, but also makes it difficult to operate flexibly when facing some narrow space or complex working environment, and cannot quickly reach the crack position for repair work, greatly reducing the construction efficiency.
[0005] On the other hand, the existing crack pouring equipment is not accurate and convenient in output control. Some equipment uses a relatively complex mechanical structure to realize the delivery of crack pouring agent, and the operation process is complicated, which requires manual adjustment of multiple components to control the output quantity and speed of crack pouring agent, and the technical level of the operator is relatively high, and operation errors are prone to occur, which leads to uneven output of crack pouring agent and affects the crack pouring quality. In addition, some equipment also has great difficulty in cleaning and maintenance. Due to unreasonable structure design, crack pouring agent is easy to remain in the internal parts of the equipment which are difficult to clean, and long-term accumulation not only affects the normal operation of the equipment, but also reduces the service life of the equipment.
[0006] At the same time, in the case of responding to the changeable direction of road cracks, the adaptability of the existing crack pouring equipment is poor. Many equipment is difficult to automatically adjust the direction to accurately move along the crack channel during movement, and the operator needs to spend a lot of time and effort to manually adjust, which increases the construction difficulty and workload, and cannot meet the requirements of efficient and accurate operation in actual construction process.
[0007] In view of the above problems existing in the existing road crack repair equipment, in order to effectively improve the efficiency and quality of road crack pouring operation, reduce construction cost and labor intensity, we design a new type of road maintenance crack pouring device.
