By inserting the air intake hood into the mounting tube on the air intake hood mounting base, the guide part slides down along the inner wall of the air intake tube by rotating the screw. The descending curved guide plate presses the insertion part, causing the insertion part to be inserted into the corresponding insertion hole on the mounting tube, thereby realizing the rapid assembly of the air intake hood and the air intake hood mounting base, replacing the traditional expansion bolt connection method, and facilitating the rapid installation and disassembly of the air intake hood.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0030] Example 1, please refer to Figure 1-10 The present invention provides the following technical solution:

[0031] Specifically, it refers to a detachable mine car air intake hood for mining engineering, including an air intake hood mounting base 1 fixedly installed on the mine car; the air intake hood mounting base 1 includes an air intake pipe 2; a fixing ring 3 is fixed to the top of the air intake pipe 2; an installation pipe 4 is fixed to the end of the fixing ring 3; an air intake hood 5 is inserted into the inner wall of the installation pipe 4; a threaded pipe 6 is fixedly fixed through the top of the air intake hood 5; a guide part 7 is provided in the threaded pipe 6 that slides and engages with the inner circumferential side of the air intake hood 5; a plurality of sliding holes 8 are evenly opened on the outer circumferential side of the air intake hood 5; a plurality of insertion holes 9 are evenly opened on the inner wall of the installation pipe 4; an insertion part 10 adapted to the guide part 7 is slidably provided in the sliding hole 8; the insertion part 10 is inserted and engaged with the corresponding insertion hole 9.

[0032] The specific application of this embodiment is as follows:

[0033] By inserting the air inlet cover 5 into the mounting tube 4 on the air inlet cover mounting base 1, and rotating the screw 19 to drive the guide part 7 to slide down along the inner wall of the air inlet tube 2, the descending guide part 7 presses against the insertion part 10, so that the insertion part 10 is inserted into the corresponding insertion hole 9 on the mounting tube 4, thereby realizing the rapid assembly of the air inlet cover 5 and the air inlet cover mounting base 1, replacing the traditional expansion bolt connection method, and facilitating the rapid installation and disassembly of the air inlet cover 5.

[0034] Example 2, please refer to Figure 1-10 This embodiment 2 is an improvement on the first embodiment as follows: Specifically, a connecting flange 11 is fixed at the bottom of the air inlet pipe 2; the connecting flange 11 is fixedly installed on the corresponding position of the mine car by fastening bolts; an installation ring 12 is fixed on the inner circumferential side of the air inlet pipe 2; an installation plate 13 is fixed on the surface of the installation ring 12 by fastening bolts; and an exhaust fan 14 is fixedly installed on the surface of the installation plate 13.

[0035] Several insert plates 15 are evenly fixed on the outer periphery of the air inlet shroud 5; several slots 16 that are evenly opened on the inner periphery of the mounting tube 4 to be inserted and matched with the corresponding insert plates 15.

[0036] The inner circumferential side of the air inlet shroud 5 is evenly provided with several lifting grooves 17; the guide part 7 includes a lifting ring 31 that slides with the inner circumferential side of the air inlet shroud 5; several lifting blocks 18 that slide with the corresponding lifting grooves 17 are fixed on the outer circumferential side of the lifting ring 31; a screw 19 that rotates with the threaded tube 6 is rotatably provided on the surface of a lifting block 18.

[0037] The insertion part 10 includes a slide rod 20 that is slidably disposed in the slide hole 8; one end of the slide rod 20 is fixed with a plug connector 21 that is inserted into the insertion hole 9; the other end of the slide rod 20 is fixed with a baffle 22; a return spring 23 sleeved on the corresponding slide rod 20 is fixedly connected between the baffle 22 and the inner circumferential side of the air inlet cover 5.

[0038] A guide ball 24 is fixed to the side of the baffle 22; an annular plate 25 coaxial with the bottom surface of the lifting ring 31 is fixed to the bottom surface of the ring 31; a number of curved guide plates 26 adapted to the guide ball 24 are evenly fixed to the outer circumference of the annular plate 25; the guide ball 24 is pressed against the curved guide plate 26 under the elastic force of the return spring 23.

[0039] One specific application of this embodiment is:

[0040] In the initial state, under the elastic force of the return spring 23, the guide ball 24 is pressed against the curved guide plate 26, and the outer peripheral side of the curved guide plate 26 points from the lifting ring 31 to the annular plate 25 (i.e., Figure 6 The plate 15 on the air inlet shroud 5 gradually thins from top to bottom. It slides down along the slot 16 on the inner side of the mounting tube 4. When the plate 15 is placed in the slot 16, the corresponding sliding hole 8 and the insertion hole 9 are coaxially set. The screw 19 is rotated to make it rotate down along the threaded tube 6, thereby driving the lifting block 18 on the guide part 7 to slide down along the corresponding lifting groove 17. During the sliding descent of the guide part 7, the curved guide plate 26 on it slides down and squeezes the corresponding guide ball 24, which drives the slide rod 20 to slide along the sliding hole 8. This causes the insertion part 21 to slide out from the corresponding sliding hole 8 and insert into the corresponding insertion hole 9, so that multiple sets of insertion parts 10 are simultaneously inserted into the insertion holes 9 on the mounting tube 4. This achieves one-time positioning of the air inlet shroud 1 and completes the rapid assembly of the air inlet shroud 5 and the air inlet shroud mounting base 1. At the same time, it facilitates the rapid disassembly of the air inlet shroud 5 and the air inlet shroud mounting base 1, replacing the traditional expansion bolt connection method and improving the assembly efficiency of the air inlet shroud 5.

[0041] Example 3, please refer to Figure 1-10 This embodiment three is an improvement on the embodiment two. Specifically, the outer circumferential side of the mounting pipe 4 is provided with an external thread 27; the external thread 27 is provided with a threaded ring 28; the outer circumferential side of the threaded ring 28 is fixed with a handle 29; and a number of cover plates 30 that are adapted to the outer circumferential side of the air inlet shroud 5 are uniformly fixed on the top of the threaded ring 28.

[0042] One specific application of this embodiment is:

[0043] After the air inlet shroud 5 and the air inlet shroud mounting base 1 are assembled, rotate the threaded ring 28 to make it rotate and descend along the external thread 27 until each set of cover plates 30 covers the top of the corresponding slot 16, preventing the air inlet shroud 1 from accidentally detaching from the air inlet shroud mounting base 1, improving the practical safety of the device, realizing secondary positioning of the air inlet shroud 5, and further improving the stability of the connection between the air inlet shroud 5 and the air inlet shroud mounting base 1.

[0044] When it is necessary to remove the air inlet cover 5 from the air inlet cover mounting base 1, first rotate the threaded ring 28 in the opposite direction to make it rotate and rise along the external thread 27 until each set of cover plates 30 rotates and rises away from the top of the slot 16, releasing the secondary limit on the air inlet cover 5. Then, rotate the screw 19 in the opposite direction to make it rotate and rise along the threaded tube 6, thereby driving the guide part 7 to slide and rise, so that the curved guide plate 26 slides and rises. Under the elastic reset force of the reset spring 23, the slide rod 20 is driven to slide and reset along the corresponding slide hole 8 until the plug 21 disengages from the corresponding plug hole 9. Finally, the plug 21 is stored in the corresponding slide hole 8, releasing the primary limit on the air inlet cover 5. The air inlet cover 5 can then be directly removed from the air inlet cover mounting base 1. The operation is simple and easy to use.
