Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to road construction tool technical field, concretely relates to an asphalt paving and pushing flat heater. BACKGROUND
[0002] Asphalt pavement is a pavement structure that a certain thickness of asphalt mixture is paved on the flexible base layer and semi-rigid base layer.
[0003] When the road is paved with asphalt, the asphalt needs to be heated first and then paved on the road, and then the pushing flat equipment is used to flatten the places that cannot be paved flat by machines such as road edges, turntables or paths, and finally the paved asphalt pavement is compacted. However, when paving work is carried out in a low temperature environment (for example, in winter), the asphalt hardens quickly due to the low temperature, and the pushing flat equipment needs to be heated when the staff uses the pushing flat equipment to pave. The traditional heating method is to use fire to roast the pushing flat equipment to heat it, so as to help the pushing flat equipment to quickly pave the asphalt, but the fire roasting method is not safe, pollutes a lot, does not meet the environmental protection requirements, and does not meet the green construction standard.
[0004] Therefore, an asphalt paving and pushing flat heater is designed. CONTENT OF THE UTILITY MODEL
[0005] The utility model provides an asphalt paving and pushing flat heater to solve the above problems.
[0006] The utility model is realized through the following technical schemes: an asphalt paving and pushing flat heater, characterized by comprising a shell, a heating coil is arranged in the shell, a heating plate is arranged on the upper surface of the heating coil, the heating plate is in contact with the heating coil, the initial end of the heating coil is connected with a controller through a wire, the controller is connected with a plug through a wire, the other end of the plug is also connected with the tail end of the heating coil through a wire, the plug is plugged into an external power socket, and a sensor is arranged on one side of the heating plate and connected with the controller.
[0007] Further, the heating plate is made of high-temperature heat-conducting glass.
[0008] Further, the sensor is used to sense whether the pushing flat equipment is placed on the heating plate.
[0009] The utility model has the advantages that the coil is electrified to generate heat energy, which is transmitted to the iron pushing flat equipment, so that the temperature of the pushing flat equipment is increased, the pushing flat equipment is convenient to use for paving asphalt under low temperature conditions, and the working efficiency is improved.
[0010] The utility model has the advantages of low cost, simple structure, convenient use, good safety, no pollution, and meeting the requirements of green and environmental protection construction. BRIEF DESCRIPTION OF DRAWINGS

[0014] In order to make the purpose, technical scheme and beneficial effect of the utility model more clearly, the technical scheme in the utility model is further explained below in combination with examples.
[0015] As shown in Figs. 1-2 , an asphalt paving and pushing heater, comprising a shell 1, a heating coil 2 is arranged in the shell 1, the heating coil 2 is made of metal with a cross-sectional area of 10mm 2 , an upper surface of the heating coil 2 is provided with a heating plate 3, the heating plate 3 is made of high-temperature heat-conducting glass, in order to make the heat energy of the heating coil 2 better transmitted to the heating plate 3, the heating plate 3 is in contact connection with the heating coil 2, a starting end of the heating coil 2 is connected with a controller 4 through a wire, the controller 4 is connected with a plug 5 through a wire, the other end of the plug 5 is also connected with a tail end of the heating coil 2 through a wire, the plug 5 is inserted into an external power socket, one side of the heating plate 3 is also provided with an inductor 6, the inductor 6 is used for sensing whether the pushing device is placed on the heating plate 3, the inductor 6 is connected with the controller 4, that is, the inductor 6 transmits a signal to the controller 4, and the controller 4 controls the power circuit of the heating coil 2 according to the signal transmitted by the inductor 6.
[0016] Generally, the pushing device adopts an iron triangular pushing device or a shovel.
[0017] In use, the device is placed on a vehicle such as a tricycle which can move along with the paving device. The plug 5 is inserted into an external power socket, and the staff places the pushing device shovel or iron triangular pushing device on the heating plate 3, at this time, the inductor 6 senses that the pushing device is placed and sends a signal to the controller 4, the controller 4 makes the heating coil 2 powered according to the signal, the heating coil 2 is heated, and then the heat energy is transmitted to the pushing device through the heating plate 3, the pushing device is placed for 20-40s, after the pushing device is heated, the pushing device can be used to push the asphalt more easily, and the phenomenon that the asphalt is solidified and difficult to be pushed due to low temperature is prevented.
