Detailed Description of the Preferred Embodiments
[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] As Figures 1 to 4 shown, a hot-fitting tooling capable of uniformly heating deep holes provided in the first embodiment includes a heating pipe 1, a transition pipe 2, and pipe connectors 3. Through holes 4 are formed on the surface of the heating pipe 1. The heating pipe 1 is used to extend into the deep hole to be heated. The transition pipe 2 is connected to the tail end of the heating pipe 1. There are two pipe connectors 3, and both of the two pipe connectors 3 are connected to the transition pipe 2. The two pipe connectors 3 are respectively used to connect an oxygen supply pipeline 5 and an acetylene supply pipeline 6.
[0028] The pipe connector 3 for connecting the oxygen supply pipeline 5 is connected to the tail end of the transition pipe 2. The pipe connector 3 for connecting the acetylene supply pipeline 6 is connected to the side surface of the transition pipe 2. Valves are installed on both of the two pipe connectors 3. When heating the deep hole, after the heating pipe 1 is inserted into the deep hole, the through hole 4 near the tail end on the side surface of the heating pipe 1 can be used as an ignition port to ignite the mixture of oxygen and acetylene gas entering the heating pipe 1.
[0029] A circular ring 7 is arranged on the surface of the heating pipe 1. The circular ring 7 is used to support on the hole wall of the deep hole to be heated. By arranging the circular ring 7, during the process of heating the deep hole by the heating pipe 1, the heating pipe 1 is located at the central position of the deep hole, so that the distances between all the through holes 4 on the surface of the heating pipe 1 and the hole wall of the deep hole to be heated are the same, making the heating of the deep hole more uniform.
[0030] A end plate 8 is arranged at the front end of the heating pipe 1. The end plate 8 seals the front end of the heating pipe 1. By arranging the end plate 8 to seal the front end of the heating pipe 1, the gas in the heating pipe 1 is sufficient, thus ensuring sufficient combustion.
[0031] As Figures 5 to 8 shown, in the second embodiment, the heating pipe 1 is set as an external thread pipe, and the circular ring 7 is threadedly sleeved outside the heating pipe 1. With this setting, different numbers of circular rings 7 can be adapted according to the length of the heating pipe 1, improving the stability of the heating pipe 1 in the deep hole.
[0032] The end plate 8 is threadedly sleeved at the front end of the heating pipe 1, so that the end plate 8 has the advantages of being convenient for disassembly and assembly on the heating pipe 1.
[0033] The circular ring 7 includes an outer ring 7.1 and an inner ring 7.2. The inner ring 7.2 is threadedly sleeved outside the heating tube 1. The outer ring 7.1 is arranged outside the inner ring 7.2, and the axial length of the inner ring 7.2 is greater than the size of the through hole 4. With such a setting, by adjusting the position of the circular ring 7, when the inner ring 7.2 moves to the outside of one circle of through holes 4 on the heating tube 1, the through holes 4 can be blocked. Furthermore, the position where the flame ejects can be adjusted to a certain extent.
[0034] The heating tube 1 includes a front tube body 1.1 and a rear tube body 1.2. The tail end of the rear tube body 1.2 is connected to the transition tube 2. The tail end of the front tube body 1.1 is inserted into the front end of the rear tube body 1.2, and the threads on the surfaces of the front tube body 1.1 and the rear tube body 1.2 are in an engaged state.
[0035] With such a setting, by increasing or decreasing the front tube body 1.1, the length of the heating tube 1 can be adjusted. By rotating the circular ring 7 to the splicing position of the two front tube bodies 1.1, the circular ring 7 is threadedly connected to the docking ends of the two front tube bodies 1.1 at the same time, achieving the effect of fixing the two front tube bodies 1.1.
[0036] The tail end of the front tube body 1.1 is provided with a protruding portion 1.3 extending axially. The inner wall surface of the front end of the front tube body 1.1 is provided with a recessed portion 1.4 for the protruding portion 1.3 to insert. When docking the front tube bodies 1.1, by inserting the protruding portion 1.3 into the recessed portion 1.4, the two front tube bodies 1.1 can be calibrated and positioned in the circumferential direction, so that the threads between the two docked front tube bodies 1.1 are positioned in an engaged state, making it more convenient to splice the heating tube 1.
[0037] The outer ring 7.1 includes a fixed ring body 7.1.1 and a movable ring body 7.1.2. The fixed ring body 7.1.1 is fixedly sleeved outside the inner ring 7.2. The movable ring body 7.1.2 is threadedly sleeved outside the inner ring 7.2, and communication holes 7.1.3 are formed on the surfaces of both the fixed ring body 7.1.1 and the movable ring body 7.1.2.
[0038] Specifically, when the movable ring body 7.1.2 is in a state of being in close contact with the fixed ring body 7.1.1, the communication holes 7.1.3 on the surfaces of the fixed ring body 7.1.1 and the movable ring body 7.1.2 are in a staggered state. By rotating the movable ring body 7.1.2 in the reverse direction to make it away from the fixed ring body 7.1.1, the communication holes 7.1.3 on the surfaces of the fixed ring body 7.1.1 and the movable ring body 7.1.2 are in a staggered state. At this time, the communication holes 7.1.3 connect the areas between adjacent two circular rings 7, making the heat dispersion more uniform.
[0039] The outer diameter of the movable ring body 7.1.2 is smaller than that of the fixed ring body 7.1.1. With such a setting, when the heating pipe 1 is located in the heated deep hole, the fixed ring body 7.1.1 supports the heating pipe 1, while the movable pipe body does not contact the inner wall of the heated deep hole and is arranged at intervals. Furthermore, during the process of pulling the heating pipe 1 in the heated deep hole, the movable ring body 7.1.2 will not malfunction.
[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
