When the pulling rod 131 moves along the length direction of the delivery pipe 110, it can drive the valve rod 114 to swing through the connecting rod 132, thereby implementing the opening and closing of the valve 112. The mounting frame 133 includes a fixing plate 1331 and two clamps 1332, and the fixing plate 1331 is fixedly connected to the heating element through the clamps 1332; the fixing plate 1331 is provided with a sliding slot 1333, and the pulling rod is slidably disposed in the sliding slot 1333. The connecting rod 132 can be made of a thin, long and flexible steel rod.
Referring to fig. 1 and 3, the heating assembly 120 includes a heating pipe 121 and a return pipe 122, wherein the heating pipe 121 has a larger diameter and is sleeved on the delivery pipe 110. The heating pipe 121 is communicated at its upper end with a hot oil supply tank, at its lower end with a return pipe 122, and the return pipe 122 is also communicated with the hot oil supply tank, thereby forming a closed circuit (the arrow in fig. 1 indicates the flow direction of the hot oil). The heating pipe 121 is connected to the delivery pipe 110 to heat or keep warm the delivery pipe 110. Specifically, the inner wall of the heating pipe 121 and the outer wall of the conveying pipe 110 are arranged at intervals to form an annular conveying channel; the hot oil in the hot oil supply tank is fed into the duct 110, and when the hot oil flows in the duct 110, it surrounds the outer wall of the heating pipe 121, thereby effectively heating the duct 110.
Referring to fig. 2 and 3, further, the heating unit 120 further includes a connector 123 for sealing the lower end of the heating pipe 121 from the outer wall of the delivery pipe 110 and for connecting the return pipe 122. The connector 123 is a frustum-shaped cylinder, the connector 123 is sleeved on the conveying pipe 110, and the edge of a small-end through hole of the connector 123 is connected with the outer wall of the pipe. A circular sealing plate 1231 is arranged at the large end of the connector 123, two through holes are formed in the circular sealing plate 1231, and the edge of the through hole in the middle is connected with the lower end of the heating pipe 121; the other through-hole edge is connected to the lower end of the return pipe 122.
Referring to fig. 4, further, in order to facilitate the maintenance of the conveying pipe 110, the conveying pipe 110 includes a conveying portion 116 and a blanking portion 118, the conveying portion 116 is disposed inside the heating pipe 121, the blanking portion 118 is disposed outside the conveying pipe 110, and the two portions are connected by a detachable joint 150. Specifically, the detachable joint 150 is a hollow pipe structure, and includes a double-threaded pipe 152, a tapered pressing piece 154 and a threaded fastener 156, and one end of the double-threaded pipe 152 is further provided with a sleeve 1521; the end of the socket 1521 is provided with a chamfer. The delivery portion 116 is a two-layer structure including an inner layer tube 1161 and an outer layer tube network 1162. When the conveying part 116 is connected to the detachable joint 150, the inner pipe 1161 is sleeved on the sleeve 1521, the tapered pressing member 154 is sleeved on the end of the inner pipe, and the end of the outer pipe network 1162 is sleeved on the tapered surface of the tapered pressing member 154. Finally, a threaded fastener 156 is placed over the tapered compression member 154 and threadedly engaged with the double-start threaded pipe 152. When the threaded fastener is tightened, the conical surface in the threaded fastener 156 can be matched with the conical surface of the conical pressing piece 154, and the outer pipe network between the two conical surfaces is pressed; meanwhile, the inner layer pipe on the ferrule is compressed by the conical surface inside the conical compression piece 154. The above-mentioned detachable joint enables the delivery section to be reliably connected; the threads on the other end of the double-start threaded pipe 152 can be connected to a valve, which is then connected to the blanking portion.
Optionally, the caulking gun 100 is further provided with a heat insulation sleeve (not shown in the figures); the thermal insulation sleeve is disposed outside the heating assembly 120, which can prevent an operator from being burned by the heating pipe 121 or the return pipe 122.
In this embodiment, an extension spring 160 is further disposed between the connecting rod 132 and the heating pipe 121; the spring force of the extension spring 160 can pull the link down, thereby keeping the valve closed.
The application method and the working principle of the caulking gun 100 provided by the embodiment are as follows:
when it is necessary to repair a gap in a road surface, the pulling rod 131 is operated to move along the sliding slot of the fixing plate 1331, and the pulling rod 131 pulls the valve rod 114 to swing through the connecting rod 132, so that the valve 112 can be opened. At this time, the hot oil in the heating pipe 121 flows along the conveying passage, and heats the conveying pipe 110 while flowing, thereby preventing the sealant from being solidified in the conveying pipe 110.
It should be noted that in other embodiments, the heating element 120 may have more variations; for example, it may be a pipe spirally wound on the outer wall of the duct 110. Or, the connector 123 may not be provided, and the bottom of the heating pipe 121 is provided with an annular sealing plate for sealing.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
