Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt spraying technology, specifically a novel asphalt spraying frame for an asphalt spraying vehicle. Background Technology
[0002] Asphalt distributors are used in highway maintenance for operations such as asphalt overlay and spraying. An asphalt distributor consists of a vehicle chassis, an asphalt tank, an asphalt pump, and a spraying system. The asphalt nozzles of the spraying system are evenly distributed on the spraying frame to spray liquid asphalt.
[0003] Asphalt distributors are quite long and take up a lot of space. They also pose a risk of collision when encountering narrow roads. When not in operation, such as when moving between sites or driving normally, the distributors need to be folded or disassembled to reduce the lateral space occupied and ensure that they do not exceed the width of the vehicle.
[0004] Furthermore, uniform application is a crucial factor in assessing the quality of the applied surface during asphalt spraying operations. The uniformity of the asphalt spraying system is primarily achieved through the even distribution of asphalt nozzles. In existing asphalt spraying trucks, the spacing between the asphalt nozzles is distributed on the spraying frame. The denser the distribution of the asphalt nozzles, the better the uniformity of the spraying effect. However, the number of asphalt nozzles distributed on a given length of spraying frame is limited, and the spraying distance between two asphalt nozzles after installation is restricted by the size of the asphalt nozzles. Therefore, the amount of emulsified asphalt sprayed per unit area during spraying operations is limited.
[0005] To address these two issues, we have developed a new type of asphalt spraying frame for asphalt spraying trucks. Utility Model Content
[0006] The purpose of this invention is to provide a novel asphalt spraying frame for an asphalt spraying vehicle, which improves the uniformity of asphalt spraying and the folding effect of the asphalt spraying frame.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel asphalt spraying frame for an asphalt spraying vehicle, comprising a rear fixed spraying frame, a front folding spraying frame, and a side folding spraying frame. The rear fixed spraying frame and the front folding spraying frame are arranged parallel to each other, one at the rear and one at the front. The rear fixed spraying frame and the front folding spraying frame are respectively hinged to both ends of a horizontally arranged scissor lift, and the rear fixed spraying frame and the front folding spraying frame are respectively fixedly connected to both ends of a retraction and extension drive mechanism. The retraction and extension drive mechanism is vertically arranged between the rear fixed spraying frame and the front folding spraying frame to drive the front folding spraying frame to move back and forth to retract and extend.
[0008] Both ends of the rear fixed sprayer and the front folding sprayer are fixed by the second retraction drive mechanism. The side folding sprayer is arranged on the left and right sides in a direction parallel to the rear fixed sprayer and the front folding sprayer. The second retraction drive mechanism is arranged parallel to the rear fixed sprayer and the front folding sprayer to drive the side folding sprayer to move left and right to retract and expand.
[0009] Asphalt nozzles are installed on the rear fixed sprayer, the front folding sprayer, and the side folding sprayer. The asphalt nozzles on the rear fixed sprayer and the front folding sprayer are evenly staggered along the length direction, and the asphalt nozzles on the front side folding sprayer and the rear side folding sprayer are evenly staggered along the length direction.
[0010] Preferably, the scissor lift, the first retraction drive mechanism, and the second retraction drive mechanism are symmetrically arranged on the rear fixed spray frame and the front folding spray frame.
[0011] Preferably, the scissor lift includes a first hinged arm and a second hinged arm, the opposite ends of the first hinged arm and the second hinged arm are hinged together, and the other end of the first hinged arm is hinged to the rear fixed sprayer, and the other end of the second hinged arm is hinged to the front folding sprayer.
[0012] Preferably, the retraction drive mechanism includes a retraction hydraulic cylinder and a telescopic sleeve. The fixed end and the telescopic end of the telescopic sleeve are respectively fixed on the rear fixed spray frame and the front folding spray frame. The two ends of the retraction hydraulic cylinder are respectively fixed on the fixed part and the telescopic part of the telescopic sleeve.
[0013] Preferably, the second retraction drive mechanism includes a telescopic hydraulic cylinder and a second telescopic sleeve. The rear fixed spray frame and the front folding spray frame are respectively fixedly connected to the corresponding fixed ends of the second telescopic sleeve. The side folding spray frame is fixedly connected to the corresponding telescopic end of the second telescopic sleeve. The two ends of the telescopic hydraulic cylinder are respectively fixed to the fixed part and the telescopic part of the second telescopic sleeve.
[0014] Preferably, both ends of the rear fixed sprayer and the front folding sprayer are provided with sliding grooves, and the side folding sprayer is slidably mounted in the sliding grooves by a sliding member.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model folds the entire asphalt spraying frame horizontally and vertically by setting up a first folding and a second folding and unfolding drive mechanism. The horizontal and vertical folding of the asphalt spraying frame reduces the space occupied and does not affect the normal driving and parking of vehicles. Moreover, the unfolding and folding of the asphalt spraying frame is easy and convenient, and the operation is simple, thus improving work efficiency.
[0017] 2. This utility model uses a rear fixed spraying frame, a front folding spraying frame, and a side folding spraying frame to set up asphalt nozzles in a double-row staggered arrangement, which increases the lateral density of the asphalt nozzles and reduces the lateral spacing between the asphalt nozzles, thereby improving the uniformity of asphalt spraying.
