Detailed Description

In order to make the technical solutions and advantages of the present invention more clearly understood, the following description is made in further detail with reference to the accompanying drawings. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict.

Fig. 1 shows a schematic structural view of one embodiment of the ironing base plate device of the present invention. As shown in fig. 1, in this embodiment, the ironing board device 100 includes an ironing board body 1, an electric heating board 2, and a lead wire (not shown in the drawing). The ironing base plate body 1 is used for leveling, shaping and pre-compacting paving materials such as asphalt concrete and stabilized soil. The electric heating plate 2 is flatly and fixedly arranged in a working area 11 in the upper surface of the ironing base plate body 1 so as to heat the ironing base plate body 1. The lead wire is arranged at the side end of the electric heating plate 2 and is used for being connected with a power supply of the paver to supply energy to the electric heating plate 2. The contact area with the ironing base plate body 1 is improved by arranging the electric heating plate 2, and the heat conduction efficiency and the heat transfer uniformity are greatly improved. Meanwhile, the heating mode can ensure that the heat loss is small, the temperature of the ironing base plate body 1 is quickly raised, the wear speed of the ironing base plate device 100 is reduced, and the construction time is saved.

In one embodiment a heat conducting layer 3 is arranged between the electric heating plate 2 and the ironing base plate body 1. Preferably, the heat conducting layer 3 is a heat conducting silicone layer formed in the working area 11 of the ironing base plate body 1 by a coating process. It is further preferred that the thickness of the thermally conductive silicone layer is 0.8-1.5 mm, for example 1 mm. Through setting up this heat-conducting layer 3, can increase the compact type between electric heating plate 2 and the ironing bottom plate body 1, can prevent on the one hand that electric heating plate 2 and the air between the ironing bottom plate body 1 from taking away the heat, on the other hand can also accelerate the heat and transmit ironing bottom plate body 1 by electric heating plate 2, improves conduction efficiency.

In one embodiment, an insulating layer 4 is provided on the upper surface of the electric-heating plate 2. Preferably, the insulating layer 4 is made of ceramic fiber paper. The heat can be well preserved under the heat preservation layer 4, and the heat loss caused by heat transfer is avoided or reduced.

The heat preservation layer 4 and the electric heating plate 2 are arranged on the ironing base plate body 1 through the fixing component 5. Specifically, a fixing plate 51 is provided on the upper surface of the insulation layer 4, and a fastener 52 is provided on the upper surface of the fixing plate 51, and a bolt 53 is provided on the ironing board body 1. The bolt 53 extends upward to pass through the heat conduction layer 3, the electric heating plate 2, the insulating layer 4 and the fixing plate 51 in sequence and then is connected with the fastener 52. The arrangement is simple and easy to realize. In a preferred embodiment, the holes provided on the fixing plate 51 for the bolts 53 to pass through may be configured as elongated holes to facilitate adjustment for easy installation.
