Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a special equipment for asphalt concrete construction. Background Technique

[0002] In the current field of special equipment and construction methods for cold patch asphalt concrete construction, the construction equipment used is a combination of general mechanical equipment for construction. The degree of construction automation is low. In winter, the temperature is low, and rain, snow, and freezing affect manual operation and construction quality.

[0003] Currently, the existing concrete construction equipment (such as patent number: CN219081098U) discloses a concrete repair construction device. By setting parts such as a fixed box and a feed inlet, repair mortar is injected into the fixed box. The driving motor is turned on to drive the stirring shaft to rotate. When the stirring shaft rotates, the repair mortar inside the fixed box can be stirred to make it more uniform. When the stirring shaft rotates, the externally sleeved and fixed scraper will also scrape the mortar on the inner wall of the fixed box, so that materials are not easily wasted during stirring, solving the problem that the slurry on the cylinder wall cannot be stirred evenly, resulting in material waste.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: in winter, under low temperature, rain, snow, ice and other conditions, the temperature has a great influence on the pouring and paving of concrete, increasing the construction difficulty. At the same time, the low temperature also affects the pouring quality of concrete, resulting in greater difficulty in winter cold patch asphalt concrete construction. Content of the Utility Model

[0025] Embodiment

[0026] As Figure 1 — Figure 7 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that under the conditions of low temperature, rain, snow, ice, etc. in winter, the temperature has a great influence on the pouring and paving of concrete, increasing the construction difficulty. At the same time, the low temperature also affects the pouring quality of concrete, resulting in great difficulty in the construction of cold-patched asphalt concrete in winter. The general idea is as follows:

[0027] Aiming at the problems existing in the prior art, the present utility model provides a special device for asphalt concrete construction, including a carrier 1, a hot air generator 2, a micro-surface sweeper module 3, a prime coat storage and spreading module 4, a storage and paving module 5, and a vibration compaction module 6.

[0028] The carrier 1 is the frame body of an engineering transport vehicle. The hot air generator 2 is installed below the front of the cab of the carrier 1. The micro-surface sweeper module 3 is installed on the front part of the chassis of the cab of the carrier 1 through connection. The prime coat storage and spreading module 4 is installed on the frame behind the cab of the carrier 1. The storage and paving module 5 is installed on the frame of the carrier 1 behind the prime coat storage and spreading module 4. The vibration compaction module 6 is installed between the front and rear wheels at the bottom of the frame. The carrier 1 is all the remaining functional components of the engineering transport vehicle except the carriage part, and is used for the installation, loading, and transportation of the device.

[0029] The hot air generator 2 is installed below the front of the cab of the vehicle 1. The hot air generator 2 includes an intake duct one 21, an intake duct two 22, a suction fan module 23, an electric heating module 24, and an exhaust duct 25. The micro surfacing sweeper module 3 is installed on the front part of the chassis of the cab of the vehicle 1 by bolts. The micro surfacing sweeper module 3 includes a frame 31, a hydraulic push rod 32, and a cleaner 33. Multiple high-strength filaments 34 are installed at the end of the cleaner 33. The prime coat storage and spreading module 4 is installed on the rear frame of the vehicle 1 behind the cab. The prime coat storage and spreading module 4 includes a prime coat storage tank 41, a liquid flow pump module 42, and a nozzle pipe 43. The inlet of the liquid flow pump module 42 is connected to the prime coat storage tank 41 through a pipe, and the nozzle pipe 43 is connected to the outlet of the liquid flow pump through a pipe.

[0030] The storage and paving module 5 is installed on the frame of the vehicle 1 behind the prime coat storage and spreading module 4. The storage and paving module 5 includes a concrete storage tank 51 and a screw conveyor module 52. The concrete storage tank 51 is in the shape of a rectangular body and is formed by assembling six steel plates. Two steel plates are installed inside the storage tank and form an inclined plane with an angle of not less than 60° with the horizontal plane. The screw conveyor body part of the screw conveyor module 52 is installed at the bottom of the aforementioned concrete storage tank 51 and forms the function of storing and transporting cold patch asphalt concrete through the two steel plates forming the inclined plane. The spreading opening of the feeding and spreading screw conveyor extends out of the concrete storage tank 51 and extends a certain distance towards the tail of the vehicle 1. The power assembly of the feeding and spreading screw conveyor extends towards the front of the vehicle to the outside of the concrete storage tank 51.

[0031] Working principle:

[0032] First step, during construction, the winter cold patch asphalt concrete construction equipment is transported to the construction site via the vehicle 1. The hot air generator 2 and the micro surfacing sweeper module 3 are turned on. The hot air generator 2 performs hot air de-icing, de-watering, and drying on the construction part to be required. The micro surfacing sweeper module 3 performs micro surfacing cleaning on the construction part to remove surface dust and sundries. The whole equipment moves forward a certain distance. The prime coat storage and spreading module 4 evenly spreads the prime coat fluid onto the construction part. The whole equipment moves forward another certain distance. The storage and paving module 5 spreads the cold patch asphalt concrete onto the construction part and is manually leveled initially, while leaving a certain surplus height. The vibration compaction module 6 is turned on, and the whole equipment moves back and forth to compact the loosely laid asphalt concrete, completing the entire construction work.

[0033] Step 2: It is hinged to the vehicle frame. The vibration compaction module 6 includes a support frame 61, a hydraulic counterweight wheel set module 62, and a hydraulic adjustment cylinder 63. The support frame 61 is a steel assembled structure, which is used to support and install the hydraulic counterweight wheel set module 62, and is connected to the support frame 61 through a hinge, and realizes circumferential movement around the aforementioned hinge center within a certain range through the expansion and contraction of the hydraulic adjustment cylinder 63, so as to realize the up and down movement of the hydraulic counterweight wheel set module 62. The hydraulic counterweight wheel set module 62 consists of an eccentric counterweight mechanism and a compaction steel wheel. Among them, the eccentric counterweight mechanism is connected to the hydraulic system through a hydraulic pipeline, and through the hydraulic control system in the vehicle 1, it realizes eccentric circular motion, drives the compaction steel wheel to make high-frequency and low-amplitude up and down vibration motion, and compacts the laid cold patch asphalt concrete. The eccentric counterweight mechanism is installed in the internal cavity of the compaction steel wheel. The compaction steel wheel is in the shape of a steel cylinder and has an internal cavity for installing the aforementioned eccentric counterweight mechanism. In particular, there is a certain proportional relationship between the weight of the eccentric counterweight mechanism and the weight of the compaction steel wheel. At the same time, the product of inertia of the eccentric counterweight mechanism can be changed in size by adjusting the moment of inertia, so as to realize the adjustable amplitude of the compaction steel wheel. The hydraulic adjustment cylinder 63 is hinged to the vehicle 1 and the support frame 61. Through the expansion and contraction of the hydraulic adjustment cylinder 63, it drives the support frame 61 to make circumferential movement around the aforementioned hinge center within a certain range, realizes the up and down movement of the hydraulic counterweight wheel set module 62, and achieves the function of leaving the ground when not in construction and compacting the road surface during construction.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limiting the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
