[0002] Bridges are prone to damage due to various accidents during use. In order to ensure their performance, the bridge deck needs to be repaired. The existing repair method is to remove the damaged parts and then re-lay asphalt. When laying asphalt, a roller is needed to flatten the asphalt.

[0003] However, in some extremely cold weather, due to the low outside temperature, the asphalt will harden quickly during paving, which can easily lead to uneven quality of repairs and affect the service life of the road surface.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-4 As shown, a bridge repair and paving device includes a heated gravity circle 1, which is a hollow tubular structure. Side plates 2 are fixedly connected to both sides of the heated gravity circle 1. The heated gravity circle 1 and the side plates 2 form a heating chamber inside the heated gravity circle 1. A plurality of position-adjustable electric heaters 9 are arranged inside the heating chamber. When the heated gravity circle 1 paves the asphalt, the area opposite to the asphalt is the main heating area. The electric heater 9 can be adjusted to a position opposite to the main heating area, so that the heat energy released by the electric heater 9 is concentratedly transmitted to the main heating area, the asphalt is heated, and the waste of heat energy is reduced.

[0024] Here, if Figure 2 As shown, since the heated gravity circle 1 needs to have load-bearing performance, the wall thickness of the heated gravity circle 1 is relatively thick, and a relatively hard material needs to be used. The material of the heated gravity circle 1 is limited. In order to reduce the loss during heat energy transfer, the inner wall of the heating chamber is fixedly connected with a heating plate 12, and the outer wall of the heated gravity circle 1 is fixedly connected with a heating plate 13. The heated plate 12 and the heating plate 13 are connected by a number of heat-conducting strips that penetrate the heated gravity circle 1, so that the heated plate 12 and the heating plate 13 can have better heat energy transmission performance.

[0025] Among them, Figure 1-2 As shown, the interior of the heating chamber is fixedly connected with at least one annular rail 8 overlapping with the center of the heated gravity circle 1, and the outer side of the annular rail 8 is slidably connected with multiple slide units 5. The two slide units 5 located at the edge are edge slides, and a driving unit is installed on the edge slide. The driving unit can control the edge slide to move on the annular rail 8. The slide unit 5 located in the middle position is the middle slide. The electric heater 9 is fixedly connected to the middle slide. The electric heater 9 can be driven to move by moving the middle slide. Elastic members 10 are installed between adjacent edge slides and middle slides and between two adjacent middle slides. Through the setting of the elastic member 10, the elasticity of the elastic member 10 can be used to automatically adjust the position of the middle slide when the edge slide moves, so that multiple electric heaters 9 are evenly distributed in the main heating area.

[0026] Furthermore, in order to enable the plurality of electric heaters 9 to form a circular array and uniformly heat the side surface of the heated gravity circle 1, the length of the elastic member 10 between the edge slide and the middle slide is 1 / 2 of the length of the elastic member 10 between two adjacent middle slides.

[0027] like Figure 3-4 As shown, the driving unit includes a motor 6 fixedly connected to the edge slide, the output end of the motor 6 is fixedly connected to a meshing ring 14, the annular rail 8 is fixedly connected to a meshing gear 7, the meshing ring 14 and the meshing gear 7 are meshingly connected, when the motor 6 is started, the meshing ring 14 can be driven to rotate, and the action force between the meshing gear 7 and the meshing ring 14 can push the slide unit 5 to slide on the outside of the annular rail 8, and at the same time, the slide unit 5 can also be equipped with an electric locking structure to lock the stopped slide unit 5.

[0028] See also Figure 2 As shown, in order to be able to adjust the position of the electric heater 9 over a larger range, a transverse axis 3 is fixedly connected between the axes of the two side panels 2, an inner support body 4 is slidably connected to the outer side of the transverse axis 3, and the inner support body 4 is fixedly connected to the annular rail 8. When the inner support body 4 slides on the outer side of the transverse axis 3, the electric heater 9 can be driven to move horizontally. An electric push rod 11 is fixedly connected to the side panel 2, and the output end of the electric push rod 11 is fixedly connected to the inner support body 4. By starting the electric push rod 11, the inner support body 4 can be driven to move horizontally.

[0029] The working principle of the utility model is as follows: when repairing a larger damaged area on a bridge, asphalt is filled in the damaged area, and then the position of the electric heater 9 is adjusted so that the electric heater 9 is evenly distributed inside the heated gravity circle 1, and then the heated gravity circle 1 is driven to move by a road roller, so that the heated gravity circle 1 can be rolled on the upper side of the damaged area to complete the asphalt paving operation. During the paving process, the pressed asphalt is heated by the electric heater 9, which can reduce the heat loss of the asphalt, prolong the softening time of the asphalt, make it more convenient to pave the asphalt, prolong the softening time of the asphalt, and improve the quality of the asphalt paving.

[0030] When repairing a smaller damaged area on the bridge, asphalt is filled in the damaged area, and then the position of the electric heater 9 is adjusted. Since the length of the damaged area is smaller than the circumference of the heated gravity circle 1 at this time, the heated gravity circle 1 needs to be repeatedly rotated less than 360° in the damaged area and move back and forth. During the rotation, a part of the heated gravity circle 1 is in contact with the asphalt, and the other part is not in contact with the asphalt. The position where the heated gravity circle 1 contacts the asphalt is the main heating area. The electric heater 9 is adjusted to a position opposite to the main heating area, so that the heat energy released by the electric heater 9 is concentrated and transmitted to the main heating area, and then the heat energy is transmitted to the asphalt through the main heating area.

[0031] In summary, the present technical solution adjusts the position of the electric heater 9, so that when repairing a smaller damaged area, the heat energy can be concentrated to heat and pave the asphalt inside the damaged area to repair it, thereby reducing the waste of heat energy.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
