Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1-4 In an embodiment of the present invention, a skid-mounted movable heating boiler for field operations includes a base 11 and rolling assemblies arranged at its four corners for easy movement.

A boiler body 21 is mounted on the upper end of the flat plate 25. A burner 22 for providing a heat source is provided on the left side of the boiler body 21. A water tank inside the boiler body 21 is connected to a water supply pump 36 for water supply. A safety valve 20 is provided on the boiler body 21 to prevent excessive air pressure. A first air supply pipe is provided on the right side of the boiler body 21. The end of the first air supply pipe is connected to the air inlet end of the coil assembly 12 through an air supply joint 15. A steam hose 14 for conveying steam is wound around the coil assembly 12. The end of the steam hose 14 is provided with a connecting flange 13 for connecting to a pipeline.

[0027] The boiler body 21 is provided with an exhaust pipe 16 for exhausting smoke, and a second steam exhaust pipe is also provided on the boiler body 21. The second steam exhaust pipe is provided with a throttle valve 19. The end of the second steam exhaust pipe is connected to a turbine 18 used as a power source. The output end of the turbine 18 is connected to the input end of the generator 17. In this way, when electricity is needed later, the throttle valve 19 can be opened to input steam to the turbine, thereby making the turbine 18 work, thereby driving the generator 17 to generate electricity to meet the field power needs.

[0028] The winding tube assembly 12 includes a winding roller 37 for winding the steam hose 14, and an air guide duct 38 is rotatably provided in a hole at the left end of the winding roller 37, and a vent 39 is opened on the air guide duct 38, and the inner wall of the winding roller 37 is provided with a buffer cavity 51 corresponding to the vent 39, and both sides of the buffer cavity 51 are provided with sealing rings 52 for sealing with the outer wall of the air guide duct 38, and the winding roller 37 where the buffer cavity 51 is located is provided with an exhaust port connected to the steam hose 14. The outer side of the air guide duct 38 is passed through the support frame 40, and the lower end of the support frame 40 is connected and fixed to the upper end of the base 11. Baffles are provided at both ends of the winding roller 37 to prevent the steam hose 14 from detaching. In actual use, the steam hose 14 can be wound around the winding tube assembly 12, and the pipeline can be retracted and released later according to the corresponding heating distance. This hose method also has low requirements on the accuracy of the take-over, which facilitates the quick take-over operation.

[0029] The fulcrum universal joint 35 includes a rectangular block 42 arranged in the middle position of the lower end of the horizontal plate 25, and a supporting ball 43 is matched in the spherical cavity at the lower end of the rectangular block 42, and the lower end of the supporting ball 43 is connected and fixed to the piston plate 44 through a connecting column, and the piston plate 44 is slidably arranged in the piston cavity 46 in the piston column, and the lower end of the piston column is connected and fixed to the base 11, and a second spring 45 for pressing the piston plate 44 is provided in the piston cavity 46, and a storage oil pool 48 for storing lubricating oil is provided at the upper end of the base 11 outside the piston plate 44, and an oil leakage port at the bottom of the storage oil pool 48 is connected to the piston cavity 46 through an oil pipe, and a one-way valve 47 is provided on the oil pipe to prevent liquid backflow, and a guide oil channel 4 is vertically provided in the supporting ball 43 and the piston plate 44 to facilitate the circulation of oil. 9.

The surface of the support ball 43 is distributed with a number of oil channels for facilitating the flow of oil. The surface of the support ball 43 is provided with a wear-resistant layer 50. In actual use, the horizontal plate 25 can rotate around the support ball 43 to adjust the horizontal angle. When the device is moved, bumps are inevitable. At this time, the second spring 45 will absorb the impact force generated by the bumps, and when bumps occur, the piston plate 44 will be forced to move downward, thereby forcing the oil inside the piston chamber 46 into the guide oil channel 49. The oil flows up to the overflow port 41 and flows down, thereby completing the lubrication of the surface of the support ball 43 and avoiding the problem of excessive wear of the support ball 43. This automatic oiling method effectively ensures the service life of the components.

[0030] The vertex support member includes a support slider 23 slidably arranged on the lower end surface of the horizontal plate 25, a guide slide bar is provided on the outside of the support slider 23, and the guide slide bar is arranged toward the fulcrum universal joint 35. One end of the guide slide bar slides through a positioning sleeve 31 provided on the lower end surface of the horizontal plate 25, and the positioning sleeve 31 and the support slider 23 are connected and fixed by a first spring 24. A displacement slider 33 is slidably provided on the upper end of the base 11 below the support slider 23, and the upper end of the displacement slider 33 is rotatably connected to the lower end of the support link 32, and the upper end of the support link 32 is rotatably connected to the lower end of the support slider 23. The displacement slider 33 is provided with transmission screw holes on the left and right sides, and an adjustment screw 34 is provided in the transmission screw hole in parallel with the guide slide rod. One end of the adjustment screw 34 is rotatably connected to the fixed block, and the other end is connected to the output end of the fine-tuning motor 30. Under the action of the fine-tuning motor 30, the adjustment screw 34 and the displacement slider 33 rotate relative to each other. Under the action of the thread, the displacement slider 33 slides along the upper end of the base 11, thereby adjusting the height of the support slider 23. By adjusting the height of the three points respectively, the horizontal degree of the horizontal plate 25 is adjusted, so that the boiler body can adapt to complex terrain in the field.

[0031] The rolling assembly includes a support seat 27 arranged at the end of the base 11, and a storage groove 28 is provided at the lower end of the support seat 27. A moving wheel 29 is provided inside the storage groove 28. The shaft end of the moving wheel 29 is fixedly connected to the output end of the lifting push rod 26. The lifting push rod 26 is installed at the upper end of the support seat 27. In this way, when transporting, the lifting push rod 26 drives the moving wheel 29 to extend downward into the storage groove 28, thereby supporting the entire device, so that the device is in rolling connection with the ground.

[0032] The working principle of the present invention is: during actual use, the base 11 is placed on the ground in the field, and the entire device is lifted up by driving the moving wheel 29 through the lifting push rod 26, and then the position of the device is fine-tuned as needed. After fine-tuning, under the action of the fine-tuning motor 30, the adjusting screw 34 and the displacement slider 33 rotate relative to each other. Under the action of the thread, the displacement slider 33 slides along the upper end of the base 11, thereby adjusting the height of the support slider 23. By adjusting the height of the three points respectively, the horizontal degree of the horizontal plate 25 is adjusted, so that the boiler body can adapt to the complex terrain in the field. At this time, the boiler body 21 is in a horizontal state, and then the steam hose 14 is removed from the winding pipe assembly 12, so that the connecting flange 13 at the end of the steam hose 14 is connected to the end of the steam supply pipe, thereby providing hot air for life in the field. When electricity is needed later, the throttle valve 19 can be opened to input steam into the turbine, so that the turbine 18 works, thereby driving the generator 17 to generate electricity to meet the power needs in the field.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
