Description

Technical Field

[0001] The utility model relates to the technical field of pavement maintenance, in particular to a highway subgrade and pavement maintenance construction equipment. Background Technique

[0002] After the expressway is opened to traffic and put into use, due to the influence of factors such as vehicle load and natural environment, damage phenomena will occur after a certain period of time, such as potholes and cracks. If the damaged pavement is not repaired in time, under the action of vehicle load and rainwater, the pavement will be damaged more and more seriously. Therefore, maintenance construction equipment is needed.

[0003] When repairing cracks, it is often to use a spray gun to apply the repair liquid on the surface of the crack to carry out the repair work. When the existing spray gun is working, it is necessary to align and approach the nozzle to the crack, and it is difficult to grasp the distance, which is easy to make the nozzle contact and rub against the bottom surface, resulting in damage to the nozzle. Therefore, we propose a highway subgrade and pavement maintenance construction equipment. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a highway subgrade and pavement maintenance construction equipment, which can control the distance between the gun body and the bottom surface, avoid the friction between the spray pipe and the bottom surface, and design a telescopic spray pipe to facilitate the protection of the spray pipe, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A highway subgrade and pavement maintenance construction equipment, including a gun body, the right parts of the front and rear side surfaces of the gun body are respectively fixedly connected to the left ends of brackets, the right ends of the two brackets are respectively installed with rollers, a sliding hole is opened at the right end of the gun body, a piston plate is arranged at the right part inside the gun body, the piston plate is slidably connected to the inner wall of the gun body, a through hole is opened in the middle of the piston plate, the right end of the through hole is communicated with the left end of the spray pipe, the right end of the spray pipe is slidably connected to the sliding hole and extends to the outside of the gun body through the sliding hole, the right end of the piston plate is fixedly connected to the left end of a spring, the right end of the spring is fixedly connected to the right end of the inner wall of the gun body, and a feeding mechanism is installed at the left part inside the gun body.

[0006] The piston plate is designed so that the flow of the repair fluid in the gun body drives the piston plate to move automatically to the right, thereby driving the nozzle to extend automatically, which is convenient for operation. A telescopic nozzle is designed so that when not working, the nozzle can retract automatically, thus better protecting the nozzle. Brackets and rollers are designed so that the nozzle maintains an appropriate distance from the bottom surface, thus avoiding contact between the nozzle and the bottom surface and preventing damage to the nozzle. When the control device works, first put the repair fluid into the gun body, then hold the gun body against the bottom surface obliquely by hand so that the rollers are in contact with the bottom surface, and then move the repair fluid to the right side of the gun body through the feeding mechanism, thereby pushing the piston plate to move to the right, driving the nozzle to extend, so that after the nozzle approaches the crack, the repair fluid is ejected to repair the crack.

[0007] Further, the feeding mechanism includes a motor. The left end of the gun body is fixedly connected to the motor. The input end of the motor is electrically connected to the output end of an external power supply through an external control switch group. The output shaft of the motor passes through a circular hole opened on the gun body and extends into the interior of the gun body, and is fixedly connected to the left end of a rotating rod. The outer surface of the rotating rod is fixedly connected to a feeding screw.

[0008] The feeding screw is designed so that the feeding work is carried out by the feeding screw during rotation. During the feeding work, the repair fluid is stirred to prevent the repair fluid from solidifying. When controlling the feeding mechanism to work, first control the motor to work through the external control switch group, thereby driving the rotating rod to rotate, driving the feeding screw to rotate, and forcing the repair fluid to move to the right.

[0009] Further, the construction equipment also includes a feeding port. The left part of the upper surface of the gun body is connected to the feeding port, and the upper part of the left surface of the gun body is connected to an air outlet. A one-way valve is arranged inside the air outlet.

[0010] The air outlet is designed to adjust the air pressure inside the gun body when loading the repair fluid, making the loading faster.

[0011] Further, the construction equipment also includes a fixing groove. The upper end of the feeding port is fixedly connected to the fixing groove, and the fixing groove is used to fix the conveying pipe.

[0012] The fixing groove is designed to butt and fix the external conveying pipe through the fixing groove, which is more convenient.

[0013] Further, the construction equipment also includes heating rods. The front and rear parts of the inner surface of the gun body are respectively horizontally fixedly connected to the heating rods.

[0014] The heating rods are designed to heat the repair fluid through the heating rods to prevent the repair fluid from cooling and solidifying. When controlling the heating rods to work, control the heating rods to work through the external control switch group.

[0015] Furthermore, the construction equipment further includes a handle, and the left part of the lower surface of the gun body is fixedly connected to the handle.
