At this time, the two semi-cylindrical rotating blocks are locked in the two semi-circular ring limiting plates to achieve the purpose of fixation. When disassembling, the limiting connecting rod can be pulled to separate the two protective frames, so that multiple protective frames can be easily fixed together, improving work efficiency and work safety.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example: A tunnel micropile construction retaining device, referring to... Figure 1 ,to Figure 3A tunnel micropile construction retaining device includes a longitudinal support frame 1. The longitudinal support frame 1 mainly provides a basic bearing structure for supporting the transverse base 2, lifting mechanism 3, and quick fixing mechanism 4 of the support frame, and also provides installation space for the sliding of the telescopic component 36. The transverse base 2 is fixedly connected to the bottom of the longitudinal support frame 1. The transverse base 2 mainly increases the contact area between the longitudinal support frame 1 and the tunnel ground, improving the stability of the entire retaining device on the ground. Two lifting mechanisms 3 are fixedly connected to the top two sides of the longitudinal support frame 1. The lifting mechanism 3 mainly realizes the height adjustment of the top hanging net component 37 through the cooperation of internal components, and also provides support for the top installation of the protective net 39. Two supports are fixedly connected to the middle two sides of the longitudinal support frame 1. The quick-fixing mechanism 4 and the lifting mechanism 3 include two L-shaped limiting plates 31. The L-shaped limiting plates 31 mainly fix the fixing plates 32 to the top two sides of the longitudinal support frame 1, and at the same time limit the sliding direction of the telescopic component 36. The adjacent sides of the two L-shaped limiting plates 31 are fixedly connected to the top two sides of the longitudinal support frame 1. The top of the L-shaped limiting plates 31 is fixedly connected to the fixing plate 32. The fixing plate 32 mainly provides a fixed installation position for the limiting block 33, and at the same time provides support for the sliding of the inserted fixing column 35. The left side of the fixing plate 32 is fixedly connected to the limiting block 33. The limiting block 33 mainly provides sliding space for the inserted fixing column 35, and at the same time cooperates with the pull plate 341 to fix the limiting spring 342. The left side of the limiting block 33 is fixedly connected to the pull plate 341. The moving component 34, or pull-out component 34, mainly moves the insertion fixing post 35 by operating the pull plate 341. It works in conjunction with the limit spring 342 to control the fixed state of the telescopic component 36. The pulling component 34 includes the pull plate 341, which provides a force application point for the operator, causing the insertion fixing post 35 to move left and right. The right side of the pull plate 341 is fixedly connected to the left side of the insertion fixing post 35, and the right side of the pull plate 341 is also fixedly connected to the limit spring 342. The limit spring 342 generates elastic force after the pull plate 341 is released, pushing the insertion fixing post 35 back to the insertion hole 362. The limit block 33 has the insertion fixing post 35 slidably connected inside. The insertion fixing post 35 mainly moves by inserting the telescopic post 36. The insertion holes 362 of 61 fix the telescopic component 36 at a designated height position on the longitudinal support frame 1. The telescopic components 36 are slidably connected to the interior of both sides of the longitudinal support frame 1. The telescopic components 36 mainly change their length by sliding the telescopic column 361 within the longitudinal support frame 1, thereby adjusting the height of the top hanging net component 37. The telescopic component 36 includes the telescopic column 361, which mainly provides bottom support for the crossbeam 371. Simultaneously, it is fixed by cooperating with the insertion fixing column 35 through the insertion holes 362. The telescopic column 361 is slidably connected to the interior of both sides of the longitudinal support frame 1. Multiple insertion holes 362 are provided inside the telescopic column 361, which mainly provide insertion positions for the insertion fixing column 35.The telescopic column 361 is fixed at different heights by cooperating with the insertion fixing post 35. The external sliding connection of the insertion fixing post 35 is to the inside of the telescopic column 361, the external sliding connection of the insertion fixing post 35 is to the inside of the fixing plate 32, and the external sliding connection of the insertion fixing post 35 is to the inside of the limiting block 33. The top of the two telescopic components 36 is fixedly connected to the top of the top hanging net assembly 37. The top hanging net assembly 37 mainly installs the top of the protective net 39 through the top hook 372, and at the same time connects the two telescopic components 36 into one unit through the crossbeam 371. Specifically, the device is placed at the designated location in the tunnel construction area. The transverse base 2, in conjunction with the longitudinal support frame 1, initially stabilizes the device. Then, the lifting mechanism 3 is operated. First, the pulling plate 341 of the pulling component 34 is pulled. The pulling plate 341 causes the insertion fixing column 35 to slide inside the fixing plate 32 and the limiting block 33. The limiting spring 342 is compressed and deformed as the pulling plate 341 is pulled. At this time, the telescopic column 361 of the telescopic component 36 can move along the interior of the longitudinal support frame 1. The L-shaped limiting plate 31 restricts the sliding direction of the telescopic column 361. After the telescopic column 361 is adjusted to the required height, the pulling plate 341 is released. The limiting spring 342 returns to its original state and pushes the insertion fixing column 35 into the insertion hole 362 of the telescopic column 361, so that the telescopic column 361 is fixed in the corresponding position of the longitudinal support frame 1. After the telescopic component 36 is fixed, it drives the top hanging net component 37 to maintain at the set height.

[0013] The top hanging net assembly 37 includes a crossbeam 371, which mainly connects the tops of the two telescopic components 36 and provides a fixed installation position for the top hooks 372. The bottom of the crossbeam 371 is fixedly connected to the tops of the two telescopic components 36. Top hooks 372 are fixedly connected to the outer sides of the crossbeam 371 respectively. The top hooks 372 mainly provide a hanging position for the top of the protective net 39, enabling quick installation of the top of the protective net 39. The bottom of the longitudinal support frame 1 is slidably connected to a driven hanging net assembly 38. The driven hanging net assembly 38 mainly provides a hanging position for the bottom of the protective net 39 through the bottom hooks 383, and works with the top hanging net assembly 37 to achieve the overall installation of the protective net 39. The driven hanging net assembly 38 includes two T-shaped grooves 381. The groove 381 mainly provides a sliding track for the I-shaped slider 382, ​​limiting the movement direction of the I-shaped slider 382. Two T-shaped grooves 381 are opened inside both sides of the longitudinal support frame 1. The I-shaped slider 382 is slidably connected inside the T-shaped grooves 381. The I-shaped slider 382 mainly connects the T-shaped grooves 381 and the bottom hook 383, driving the bottom hook 383 to move along the T-shaped grooves 381. The bottom hook 383 is fixedly connected to the outside of the I-shaped slider 382. The bottom hook 383 mainly provides a hanging position for the bottom of the protective net 39, facilitating the installation and removal of the bottom of the protective net 39. The protective net 39 is fixedly connected to the outside of the top hanging net assembly 37. The protective net 39 mainly covers the side of the device to prevent the surrounding rock fragments from falling during the tunnel construction process. Specifically, after the telescopic component 36 is fixed, it drives the crossbeam 371 of the top hanging net component 37 to maintain at the set height. Then, the top of the protective net 39 is hung on the top hooks 372 on both sides of the crossbeam 371. Next, the I-shaped slider 382 of the driven hanging net component 38 is pushed to slide along the T-shaped grooves 381 inside both sides of the longitudinal support frame 1. The I-shaped slider 382 drives the bottom hook 383 to move to a position that matches the bottom of the protective net 39. Then, the bottom of the protective net 39 is hung on the bottom hook 383, so that the protective net 39 covers the side of the device.

[0014] Reference Figures 2 to 5The quick-fixing mechanism 4 of the support frame includes an L-shaped connecting shell 41. The L-shaped connecting shell 41 mainly provides a fixed installation space for the limiting base plate 42, the semi-circular ring-shaped limiting plate 43, and the connecting column 45. The right side of the L-shaped connecting shell 41 is fixedly connected to the outside of the longitudinal support frame 1. The bottom of the L-shaped connecting shell 41 is fixedly connected to the limiting base plate 42. The limiting base plate 42 mainly increases the contact area between the L-shaped connecting shell 41 and the longitudinal support frame 1, enhancing the installation stability of the L-shaped connecting shell 41. The left side of the inside of the L-shaped connecting shell 41 is fixedly connected to the semi-circular ring-shaped limiting plate 43. The annular limiting plate 43 mainly limits the movement and rotation range of the limiting connecting rod 441 and the semi-cylindrical rotating block 442 through its internal limiting groove. A connecting assembly 44 is rotatably and slidably connected inside the semi-circular annular limiting plate 43. The connecting assembly 44 is mainly connected to the external fixed structure of the roadway through the limiting connecting rod 441, thus fixing the L-shaped connecting shell 41 to the external structure. The connecting assembly 44 includes the limiting connecting rod 441, which mainly connects the semi-cylindrical rotating block 442 to the external fixed structure, transmitting the fixing force. The bottom outer side of the limiting connecting rod 441 slides... The limiting connecting rod 441 is slidably connected to the limiting groove opened at the top of the semi-circular limiting plate 43, and the middle part of the limiting connecting rod 441 is slidably connected to the limiting groove opened at the L-shaped connecting housing 41. The bottom of the limiting connecting rod 441 is fixedly connected to a semi-cylindrical rotating block 442. The semi-cylindrical rotating block 442 mainly rotates inside the semi-circular limiting plate 43, driving the limiting connecting rod 441 to adjust the connection angle. The outside of the semi-cylindrical rotating block 442 is slidably connected to the inside of the semi-circular limiting plate 43. The outside of the connecting assembly 44 is fixedly connected to the top of the connecting pull spring 46, and the bottom of the L-shaped connecting housing 41 is fixedly connected to the top of the connecting pull spring 46. A connecting column 45 is fixedly connected to the side. The connecting column 45 mainly provides a fixed position for the bottom of the connecting pull spring 46 and supports the connecting pull spring 46. The connecting pull spring 46 is fixedly connected to the top of the connecting column 45. The connecting pull spring 46 mainly generates elastic tension to pull the connecting assembly 44 back to its original position, ensuring a stable connection between the connecting assembly 44 and the external structure. The left side of the limiting block 33 is fixedly connected to the right side of the limiting spring 342. The bottom sides of the protective net 39 are fixedly connected to the outside of the driven hanging net assembly 38. The bottom of the fixing plate 32 is fixedly connected to the top of the longitudinal support frame 1. Specifically, when operating the quick-fixing mechanism 4 of the support frame, firstly, inside the L-shaped connecting housing 41, the semi-cylindrical rotating block 442 of the connecting assembly 44 is rotated through the internal limiting groove of the semi-circular ring-shaped limiting plate 43. The semi-cylindrical rotating block 442 drives the limiting connecting rod 441 to adjust to an angle that matches the external fixing structure of the roadway. The limiting base plate 42 helps maintain the stability of the L-shaped connecting housing 41 outside the longitudinal support frame 1. Then, the limiting connecting rod 441 is connected to the external fixing structure of the roadway, and subsequently, the connecting pull spring 46 supported by the connecting column 45 generates... The elastic tension pulls the connecting component 44 back to its original position, ensuring a stable connection between the limiting connecting rod 441 and the external fixed structure. At the same time, the L-shaped connecting shell 41 provides installation space for the limiting base plate 42, the semi-circular limiting plate 43, and the connecting column 45, ensuring that the fixing function of the support frame quick fixing mechanism 4 is effectively performed. During this period, the left side of the limiting block 33 remains connected to the right side of the limiting spring 342, the bottom sides of the protective net 39 remain connected to the outside of the driven hanging net assembly 38, and the bottom of the fixing plate 32 remains connected to the top of the longitudinal support frame 1.

[0015] The implementation principle of this application embodiment is as follows: The horizontal base 2 increases the contact area between the longitudinal support frame 1 and the ground, and the auxiliary device is placed stably. Then, when adjusting the lifting mechanism 3, the operator pulls the pull plate 341 of the pull assembly 34, which drives the insertion fixing column 35 to slide within the fixing plate 32 and the limiting block 33. The limiting spring 342 is compressed. At this time, the telescopic column 361 of the telescopic assembly 36 can slide within the longitudinal support frame 1. The L-shaped limiting plate 31 limits the sliding direction of the telescopic column 361, adjusting the telescopic column 361 to the required height. After releasing the pull plate 341, the limit spring 342 pushes the insertion fixing post 35 into the insertion hole 362 of the telescopic post 361 to fix the telescopic post 361. Then, install the protective net 39, hooking the top of the protective net 39 onto the top hook 372 on the outside of the crossbeam 371 of the top hanging net assembly 37. Next, push the I-shaped slider 382 of the driven hanging net assembly 38 to slide in the T-shaped groove 381, driving the bottom hook 383 to move and hooking the bottom of the protective net 39 onto the bottom hook 383, completing the installation and fixing of the protective net 39. When operating the quick-fixing mechanism 4 of the support frame, first adjust the limiting connecting rod 441 of the connecting component 44 so that the semi-cylindrical rotating block 442 rotates within the semi-circular ring limiting plate 43, connecting the limiting connecting rod 441 to the external fixed structure of the roadway. The connecting pull spring 46 generates elastic tension under the support of the connecting column 45 to pull the connecting component 44 back to its original position. The L-shaped connecting shell 41 and the limiting base plate 42 help ensure the stability of the connection.
