Description

Technical Field

[0001] The utility model mainly relates to the technical field of boiler headers, and in particular to a high-efficiency intelligent drilling device for headers. Background Art

[0002] The header is a pipe fitting used to mix the boiler's working fluid and ensure uniform heating. The furnace walls of industrial boilers are typically constructed from rows of pipes (water walls). However, boilers are large and complex, and it's difficult to guarantee uniform heat absorption for the working fluid in all tubes. Heat absorption varies significantly across different locations. Installing a header allows the working fluid in each tube to converge and be distributed to the next level of tubes. This reduces thermal deviations, optimizing the working fluid's heat absorption, flow, boiler cooling, and overall thermal efficiency. Furthermore, the sizes, numbers, and layouts of the pipes in the upper, middle, and lower sections of the boiler vary. The header connects these sections to ensure smooth flow of the working fluid.

[0003] For example, Chinese patent publication number CN209532179U provides a drilling device for a boiler header, comprising a clamping assembly and a drilling assembly. The clamping assembly includes a base, a rotary chuck mechanism, a lower guide wheel mechanism, an upper guide wheel mechanism, and an upper clamping mechanism. The drilling assembly includes a support, a crossbeam, a pulley mechanism, a drilling seat, and a drilling machine. However, since the header is connected to many branch pipes, it is necessary to drill holes in the header. Since the header is a tubular member, holes need to be drilled one by one along the length of the header. The existing clamp affects the drilling position, requiring re-clamping before drilling. Using ordinary drilling devices is too inefficient, and the header is difficult to transport. The drilling devices in the prior art are not equipped with loading and unloading devices, and manual handling is labor-intensive. Utility Model Content

Example

[0029] Refer to the attached Figures 1 to 5 , an efficient intelligent drilling device for headers, comprising a drilling machine 1, a workbench 2 provided on the drilling machine 1, and a plurality of fixing mechanisms 3 for fixing headers 4 provided on the workbench 2. Figure 2 As shown, three fixing mechanisms 3 secure the welded header 4, which can also be used during welding. The fixing mechanisms 3 include two symmetrically arranged clamping seats 6, one of which is provided with a rope winding assembly 7, and the other clamping seat 6 is provided with a pull ring 8. The rope winding assembly 7 includes a steel wire rope 73, one end of which is connected to the pull ring 8. Loading and unloading mechanisms 5 are also provided at both ends of the workbench 2.

[0030] The clamping seat 6 includes a mounting frame 61 , a clamping plate 62 is obliquely provided at the upper end of the mounting frame 61 , and a connecting leg 63 is provided at the lower end of the mounting frame 61 , and the connecting leg 63 is fixedly connected to the workbench 2 .

[0031] The rope winding assembly 7 includes two symmetrically mounted mounting plates 71, between which a rope winding wheel 72 is rotatably mounted, and a steel wire rope 73 is wound around the rope winding wheel 72. A locking mechanism is also provided on the mounting plates 71 for preventing the rope winding wheel 72 from rotating.

[0032] A driven gear 74 is fixedly mounted on the side of the rope winding wheel 72, and the driven gear 74 is engaged with the driving gear 75. The driving gear 75 is fixed on the rotating shaft 76, and the rotating shaft 76 is rotatably mounted between the mounting plates 71. One end of the rotating shaft 76 extends out of the mounting plate 71 and is connected to the crank 77.

[0033] The loading and unloading mechanism 5 includes a first support plate 51 and a second support plate 52 arranged parallel from bottom to top. A support block 53 is provided at the upper end of the second support plate 52. A V-shaped support groove is provided on the support block 53. Four rollers 56 are provided at the lower end of the first support plate 51. The rollers 56 are arranged on a slide rail 57. The slide rail 57 is arranged on both sides of the drilling machine 1.

[0034] A screw rod 54 is fixedly mounted on the upper end of the first support plate 51 , and a locking nut 55 is threadedly mounted on the screw rod 54 . The second support plate 52 is disposed between the two locking nuts 55 .

[0035] Working principle:

[0036] Place the header on the support groove on the support block 53, then push the loading and unloading mechanism 5, the roller 56 rotates on the slide rail 57, thereby driving the header into the fixing mechanism 3 of the drilling machine 1. In addition, the height of the second support plate 52 is adjusted by adjusting the locking nut 55 on the screw 54 to facilitate loading and unloading.

[0037] The fixing mechanism 3 is fixed to the workbench 2 via the connecting legs 63. Two inclined clamping plates 62 form a placement space for the header, which is placed between the two clamping plates 62. A rope winding assembly 7 and a pull ring 8 are installed on the clamping seat 6. One end of the wire rope 73 is fixed to the pull ring 8. By turning the crank 77, the driving gear 75 on the rotating shaft 76 rotates, thereby driving the driven gear 74 to rotate. The driven gear 74 drives the rope pulley 72 to rotate and wind the wire rope 73. Finally, a locking mechanism prevents the rope pulley 72 from rotating, thereby fixing the header via the wire rope 73, avoiding the drilling position and eliminating the need for secondary clamping. Finally, the drilling machine 1 is used to drill holes along the length of the header.
