Abstract
Description
Technical Field
[0001] This utility model relates to the field of road and bridge maintenance equipment technology, and in particular to a device for repairing high-speed crash barriers. Background Technology
[0002] Although concrete crash barriers are not part of the main structure of a bridge, the straightness and quality of their lines significantly impact the overall integrity and aesthetics of the bridge. The complex dimensions and dense reinforcement of the barriers make vibration during construction difficult in some areas, often resulting in surface roughness, grout leakage, and honeycombing after completion, all of which detract from their appearance.
[0003] To ensure the long-term use of concrete crash barriers, a lime mixture is usually sprayed onto them using spraying equipment. However, this process presents the following problems in practice:
[0004] 1. Traditional spraying equipment is usually a spray pressure can, into which a prepared lime mixture is usually put. Due to the limited capacity of the spray pressure can, the prepared lime mixture will separate over time, requiring manual stirring after each filling, which greatly increases the construction time.
[0005] 2. Because a spray gun is used as the maintenance spraying equipment, the spray gun needs to be manually pressurized each time it is used, which greatly reduces the construction efficiency of highway concrete crash barrier maintenance. Utility Model Content
[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0007] Specifically, the technical problem to be solved by this utility model is to provide a device for repairing high-speed crash barriers, so as to solve the technical problem that the current high-speed crash barrier repair equipment requires manual mixing after filling with lime mixture and manual pressurization during spraying, which greatly increases the repair time of concrete crash barriers.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] A device for repairing high-speed crash barriers includes a movable support, a mixing and storage mechanism fixedly installed on the outer surface of the movable support, and a high-pressure spraying mechanism fixedly installed on the top of the movable support.
[0010] The mixing and storage mechanism includes a first fixed frame, the outer surface of which is fixedly connected to the inner surface of the movable support, a storage hopper fixedly installed on the inner surface of the first fixed frame, a mixing component fixedly installed on the top of the storage hopper, and a feeding guide frame fixedly installed on the outer surface of the storage hopper.
[0011] As an improved technical solution, the stirring assembly includes a second fixed frame, the bottom of which is fixedly connected to the top of the storage hopper. A motor is fixedly installed on the inner surface of the second fixed frame, and a rotating shaft is fixedly installed on the output end of the motor via a reducer. A stirring rod is fixedly installed on the outer surface of the rotating shaft.
[0012] As an improved technical solution, the stirring assembly further includes a first connecting frame, one side of which is fixedly connected to the outer surface of the rotating shaft, and a second connecting frame is fixedly installed on the inner surface of the first connecting frame by bolts.
[0013] As an improved technical solution, the stirring assembly further includes a slot, which is formed on the outer surface of the second connecting frame, and a scraper is engaged on the inner surface of the slot.
[0014] As an improved technical solution, the high-pressure spraying mechanism includes a high-pressure pump, the bottom of which is fixedly connected to the top of the movable support, and a spray pipe is connected to the left side of the high-pressure pump.
[0015] As an improved technical solution, the high-pressure spraying mechanism also includes a connecting pipe, one end of which is connected to the front of the high-pressure pump, and the other end of which is connected to a valve, the top of which is connected to the bottom of the storage hopper.
[0016] After adopting the above technical solution, the beneficial effects of this utility model are:
[0017] 1. This utility model incorporates a design that continuously stirs and mixes the lime during the lime spraying process of the crash barrier maintenance device. This is achieved through the coordinated use of a motor and rotating shaft with a stirring rod and a first connecting frame; the coordinated use of the first and second connecting frames with a slot and a scraper; and the coordinated use of the stirring rod and scraper with a storage hopper. This maintains the lime in a mixed state during use, avoiding the need for manual stirring to keep the lime mixture mixed after it has been added to the spraying equipment. Furthermore, the coordinated use of the first and second connecting frames with bolts, and the coordinated use of the second connecting frame with a slot and a scraper, facilitates disassembly and cleaning.
[0018] 2. This utility model improves the maintenance efficiency of highway concrete crash barriers by adding a spraying design to the crash barrier maintenance equipment. Through the combined use of a high-pressure pump and spray pipe with connecting pipes and valves, and the combined use of valves and storage hoppers, the lime mixture can be sprayed out under high pressure. This eliminates the need for continuous manual pressurization to continuously spray the lime mixture onto the crash barrier for maintenance, thus improving the maintenance efficiency of highway concrete crash barriers.
