[0002] Boring equipment is mechanical equipment used for excavating, crushing and removing soil and rocks in tunnels, mines or underground projects, such as shield machines, tunnel boring machines and coal mine boring machines. These equipment can efficiently carry out underground operations and promote the rapid progress of engineering projects. The reasons for using support devices include ensuring safety, preventing landslides, and ensuring the safety of construction workers; maintaining the progress of excavation, preventing collapse and sliding, and ensuring the continuity and efficiency of work; protecting equipment, preventing rock and soil collapse from damaging equipment, and extending the service life of equipment; improving construction quality, providing a stable working environment, and improving the construction quality of the project; coping with complex geological conditions, effectively responding to emergencies in unstable rock formations, and ensuring the smooth progress of the project. In summary, support devices are an indispensable and important part of tunneling equipment.

[0003] In most cases, the existing supporting device adopts a hydraulic cylinder during use. The hydraulic cylinder pushes the rear legs of the equipment so that the nails under the legs are mixed into the soil, thereby achieving the effect of stabilizing the equipment. However, when encountering larger stones during use, the equipment will shake violently due to the impact of the drill bit. Long-term use will cause damage to the equipment. Therefore, a new supporting device for tunneling equipment is proposed to solve the above problem. Utility Model Content

[0007] Furthermore, the lower surface of the second rotating plate is fixedly connected to a bottom plate, and the outer wall of the bottom plate is slidably connected to a stabilizing box.

[0008] Furthermore, a fixing rod is fixedly connected to one side of the inner wall of the stabilizing box, a rack block is slidably connected to the outer wall of the fixing rod, and a second spring is sleeved on the outer wall of the fixing rod.

[0024] Specifically, by starting the hydraulic cylinder 14, the hydraulic cylinder 14 pushes the support leg 3 to contact the ground, thereby achieving initial stability; then, the hydraulic cylinder 27 is started, and the hydraulic cylinder 27 pushes the rotating plate 26 to rotate on the outer wall of the rotating plate 5, thereby enhancing the flexibility and convenience of the equipment; then, by turning the hand wheel 11, the hand wheel 11 pushes the fixed shell 12 to move, thereby causing the spring 13 metal to contract; the contraction of the spring 13 pushes the sliding rod 1402 to slide smoothly inside the fixed shell 2 1401, and further pushes the insertion rod 1403 to be inserted into the soil, thereby achieving secondary stability of the equipment; through the operation of the hand wheel 11, the spring 13 is compressed, thereby enhancing its hardness and stability, ensuring that the insertion rod 1403 will not shake, thereby achieving further stabilization effect; this process not only improves the stability and reliability of the equipment, but also enhances its convenience and practicality of operation, enabling it to work stably under various complex ground conditions.

[0025] Reference Figure 1 , Figure 2 and Figure 3, the lower surface of the rotating plate 26 is fixedly connected with a bottom plate 15, and the outer wall of the bottom plate 15 is slidably connected with a stabilizing box 16; a fixed rod 17 is fixedly connected to one side of the inner wall of the stabilizing box 16, and a rack block 18 is slidably connected to the outer wall of the fixed rod 17, and a spring 2 19 is sleeved on the outer wall of the fixed rod 17; a half gear 20 is rotatably connected to the upper surface of the stabilizing box 16, and a connecting rod 21 is fixedly connected to one side of the outer wall of the half gear 20, and the connecting rod 21 is meshed and connected with the rack block 18; a sleeve 22 is rotatably connected to the lower surface of the bottom plate 15, and the sleeve 22 is slidably connected to the connecting rod 21; a limiting rod 23 is fixedly connected to the upper surface of the stabilizing box 16, and a sliding sleeve 24 is slidably connected to the outer wall of the limiting rod 23; a spring 3 25 is sleeved on the outer wall of the limiting rod 23, and a support plate 26 is rotatably connected between the sliding sleeve 24 and the sleeve 22;

[0026] Specifically, when the rotating plate 26 moves, it pushes the bottom plate 15 to bear the pressure, and the bottom plate 15 squeezes the support plate 26 and the sleeve 22 to move downward synchronously; at this time, the rotation of the support plate 26 pushes the sleeve 24 to slide on the outer wall of the limit rod 23, thereby squeezing the spring three 25, and achieving the effect of reducing the shaking pressure; at the same time, the sleeve 22 pushes the connecting rod 21 to slide, so that the half gear 20 rotates and engages with the rack block 18; the rack block 18 slides on the outer wall of the fixed rod 17, further squeezing the spring two 19 to shrink it, thereby further reducing the shaking pressure of the equipment; this series of actions not only enhances the stability and shock resistance of the equipment, but also ensures reliable operation under various working conditions; by coordinating the linkage of various components, the equipment can better adapt to complex working environments and improve overall performance and reliability.

[0027] Working principle: when in use, first start the hydraulic cylinder 14, at this time, the hydraulic cylinder 14 pushes the leg 3 to contact the ground for preliminary stabilization, and then start the hydraulic cylinder 27, at this time, the hydraulic cylinder 27 pushes the rotating plate 26 to rotate on the outer wall of the rotating plate 5, so as to facilitate the use, and then turn the hand wheel 11, and push the fixed shell 12 to move, so as to achieve the metal contraction of the spring 13, and then the spring 13 pushes the sliding rod 1402 to slide inside the fixed shell 2 1401, and then the sliding rod 1402 pushes the insertion rod 1403 to be inserted into the soil to achieve the effect of secondary stabilization of the equipment, and the hand wheel 11 pushes the spring 13 to contract, so that the expansion and contraction force of the spring 13 is weakened and the spring 13 becomes hard, so as to achieve the effect of further stabilizing the insertion rod 1403 and preventing it from shaking;

[0028] Secondly, when the rotating plate 26 moves, it pushes the bottom plate 15 to receive the pressure. At this time, the bottom plate 15 squeezes the support plate 26 and the sleeve 22 to move downward synchronously. At this time, the rotation of the support plate 26 pushes the sleeve 24 to slide on the outer wall of the limit rod 23, thereby achieving the effect of squeezing the spring three 25 to reduce the shaking pressure. At the same time, the sleeve 22 pushes the connecting rod 21 to slide, thereby making the half gear 20 rotate, so that the half gear 20 and the rack block 18 engage and rotate. At this time, the rack block 18 slides on the outer wall of the fixed rod 17, further squeezing the spring two 19 to contract, thereby achieving the effect of further reducing the shaking pressure of the equipment.
