[0020] The following will be combined with the Figure 1 -Attached Figure 5 The technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention and do not constitute a complete set of implementations. Those skilled in the art can combine the embodiments of the present invention to derive other embodiments without inventive work, and such embodiments are also within the scope of protection of the present invention.

[0021] The inventors of this application have discovered that, currently, in the construction of hydraulic tunnel excavation, a common method is to build a trolley, and workers use handheld drilling equipment to perform drilling operations, or use a simple drilling bracket, fix the drilling equipment on the bracket, and manually adjust the position and angle of the bracket to change the drilling position. However, the method of manually holding the drilling equipment has high labor intensity for workers, low drilling efficiency, and it is difficult to ensure the drilling accuracy. The method of using a simple drilling bracket has a limited adjustment range and cannot meet the drilling requirements of different positions and angles. To this end, the present application discloses a hydraulic tunnel drilling trolley excavation construction device, which mainly adopts the following scheme: The embodiment of the present application discloses a hydraulic tunnel drilling trolley 1 excavation construction device. Figure 1, including a trolley 1 and a punching mechanism 2. A plurality of walking wheels 11 are provided at the bottom of the trolley 1 to facilitate the movement of the trolley 1. A lifting frame 3 is provided on the trolley 1 for sliding in the vertical direction, and a moving frame 4 is provided on the lifting frame 3 for sliding in the horizontal direction. A support arm 5 is rotatably provided on the moving frame 4, and a mounting frame 6 is rotatably provided on the support arm 5. The punching mechanism 2 is provided on the mounting frame 6, which can flexibly adjust the punching position and angle to meet the punching requirements of different positions and angles, reduce the labor intensity of workers, and improve the punching efficiency and accuracy.

[0022] Reference Figure 1 Specifically, the running wheels 11 are universal wheels, and each running wheel 11 is installed at the four corners of the bottom of the trolley 1 and contacts the ground, so that the trolley 1 can move freely in the tunnel. The tires of the running wheels 11 are made of wear-resistant rubber material and have good anti-slip and shock absorption properties. A plurality of outrigger cylinders 12 are also provided at the bottom of the trolley 1, and each outrigger cylinder 12 is distributed along the circumference of the trolley 1. The multiple outrigger cylinders 12 distributed circumferentially at the bottom of the trolley 1 can support the trolley 1 and perform leveling, providing a stable working foundation for the entire device, helping to improve the stability of the device during the drilling process, and thus ensuring the accuracy and quality of the drilling.

[0023] Reference Figure 1 In addition, a bracket 13 is fixed on the trolley 1 by bolts, and a winding drum 14 is rotatably provided on the bracket 13. The wires and cables of various electrical equipment or airway pipes are wound through the winding drum 14 to avoid entanglement or damage.

[0024] Reference Figure 1 On the trolley 1 and on both sides of the lifting frame 3, there are fixed guide columns 15 for driving the lifting assembly of the lifting frame 3 to move up and down; specifically, the lifting assembly includes a lead screw 16 and a servo motor 17. The lead screw 16 is vertically rotated and is arranged on the trolley 1. It is connected to the trolley 1 through a bearing to ensure its smooth rotation. The lead screw 16 is threaded with the lifting frame 3. When the lead screw 16 rotates, the lifting frame 3 will move up and down linearly along the lead screw 16. The servo motor 17 is installed on the trolley 1, and its output shaft is connected to the lead screw 16 through a coupling to accurately control the rotation of the lead screw 16, thereby realizing the precise lifting of the lifting frame 3.

[0025] Reference Figure 2Two track rods 31 are transversely mounted on the lifting frame 3. Both track rods 31 are arranged horizontally, with their lengths parallel to each other. The movable frame 4 is slidably mounted on the two track rods 31. The lifting frame 3 is provided with a first driving member 32 for driving the movable frame 4 to slide. Specifically, the first driving member 32 is a rodless cylinder fixedly mounted on the lifting frame 3, with its length parallel to that of the track rods 31. The piston of the rodless cylinder is fixedly connected to the movable frame 4. Alternatively, the first driving member 32 can be driven by a linear motor or a hydraulic cylinder.

[0026] Reference Figure 2 、 3 A main shaft 41 is rotatably provided on the movable frame 4, and the main shaft 41 is connected to the movable frame 4 through a bearing. The main shaft 41 is horizontally arranged, and the length direction of the main shaft 41 is perpendicular to the length direction of the track rod 31. The support arm 5 is fixed to the main shaft 41 by bolts. A driving motor 42 is fixedly provided on the movable frame 4, and the output shaft of the driving motor 42 is connected to the main shaft 41 through a coupling. The main shaft 41 is driven to rotate by the driving motor 42, thereby driving the support arm 5 to rotate.

[0027] Reference Figure 3 、 4 In addition, a limit plate 51 is coaxially fixed on the support arm 5, and a limit flange 43 is fixed on the movable frame 4, and the limit flange 43 coincides with the central axis of the limit plate 51. The limit plate 51 and the limit flange 43 are generally made of high-strength steel, which has good wear resistance and strength. A locking plate 44 is slidably provided on the side of the limit flange 43 away from the limit plate 51, and a plurality of limit posts 441 are provided on the locking plate 44, each limit post 441 is evenly spaced along the circumference of the locking plate 44, and a plurality of through holes 431 are provided on the limit flange 43, and the limit posts 441 correspond to the through holes 431 one by one, and the limit posts 441 are slidably passed through the corresponding through holes 431. A plurality of limit holes 511 for inserting the limit posts 441 are opened on the limit plate 51, and each limit hole 511 is evenly spaced along the circumference of the limit plate 51.

[0028] Reference Figure 4 The movable frame 4 is provided with a second driving member 45 for driving the locking plate 44 to slide. The second driving member 45 is a pneumatic cylinder. The cylinder body of the pneumatic cylinder is fixed to the movable frame 4, and the piston rod is connected to the locking plate 44, thereby driving the locking plate 44 to slide. When the support arm 5 rotates to a suitable angle, the second driving member 45 drives the locking plate 44 to slide, so that the limiting column 441 is inserted into the limiting hole 511 on the limiting plate 51, thereby locking the support arm 5, improving the stability of the support arm 5 during the drilling process, and thus improving the drilling accuracy. At the same time, this improves the safety of the construction and prevents the support arm 5 from rotating unexpectedly due to a sudden power failure of the drive motor 42 during the construction process.

[0029] Reference Figure 4 Furthermore, a plurality of mounting sleeves 442 are fixedly provided on the end surface of the locking disk 44 away from the limiting flange 43. The length direction of the mounting sleeve 442 is perpendicular to the end surface of the locking disk 44. The limiting column 441 corresponds to the mounting sleeve 442 one by one, and the limiting column 441 is slidably passed through the corresponding mounting sleeve 442, and each limiting column 441 passes through the locking disk 44. An elastic member 443 is provided in the mounting sleeve 442. The elastic member 443 is generally a spring. One end of the spring rests on the inner wall of the mounting sleeve 442, and the other end rests on the limiting column 441, driving the limiting column 441 to slide toward the limit disk 51. Through the above design, even if the limit column 441 is not accurately aligned with the limit hole 511 on the limit plate 51, the locking plate 44 can still slide normally. At this time, the limit column 441 enters the installation sleeve 442 and the spring is compressed; if the support arm 5 rotates unexpectedly during construction, when the support arm 5 rotates to a certain angle, the limit column 441 is accurately aligned with the limit hole 511 on the limit plate 51. At this time, the limit column 441 is inserted into the limit hole 511 under the elastic force of the spring, and can still achieve the limitation of the support arm 5, thereby ensuring the safety of construction.

[0030] Reference Figure 2 、 5 The mounting frame 6 is arranged at the end of the support arm 5 away from the movable frame 4, and the rotation axis of the mounting frame 6 is parallel to the length direction of the track rod 31. The support arm 5 is provided with a driving assembly for driving the mounting frame 6 to rotate; specifically, the driving assembly includes a pushing cylinder 52 and a connecting rod 53. The pushing cylinder 52 is hingedly arranged on the support arm 5, and one end of the connecting rod 53 is hingedly connected to the piston rod of the pushing cylinder 52, and the other end is fixedly connected to the mounting frame 6. When the piston rod of the pushing cylinder 52 is extended or retracted, the connecting rod 53 drives the mounting frame 6 to rotate around the rotation axis at the end of the support arm 5, thereby adjusting the angle of the punching mechanism 2. An electric push rod and a rocker mechanism can also be used to replace the pushing cylinder 52 and the connecting rod 53, and the rotation of the mounting frame 6 can also be achieved.

[0031] Reference Figure 5 The drilling mechanism 2 includes a propulsion frame 21, a hydraulic cylinder 22, a drill rod 23, a drill bit 24, and a motor 25. Two guide rods 61 are fixedly provided on the mounting frame 6. The length directions of the two guide rods 61 are perpendicular to the rotation axis of the mounting frame 6 and the length directions of the two guide rods 61 are parallel. The propulsion frame 21 is slidably sleeved on the two guide rods 61. The drill rod 23 is rotatably provided on the propulsion frame 21, and the length direction of the drill rod 23 is parallel to the length direction of the guide rods 61. The drill rod 23 is connected to the propulsion frame 21 via a bearing. The drill bit 24 is fixedly provided at the end of the drill rod 23. The motor 25 is fixedly installed on the propulsion frame 21, and the output shaft of the motor 25 is connected to the drill rod 23 via a coupling, thereby driving the drill rod 23 and the drill bit 24 to rotate.

[0032] Reference Figure 5 Buffer racks 62 are also slidably mounted on the two guide rods 61. The cylinder body of the hydraulic cylinder 22 is fixed to the mounting frame 6. The piston rod of the hydraulic cylinder 22 is connected to the buffer rack 62. An elastic buffer member 63 is provided between the buffer rack 62 and the propulsion frame 21. The elastic buffer member 63 is a compression spring. The compression spring is mounted on each guide rod 61, and the ends of the compression spring abut against the buffer rack 62 and the propulsion frame 21, respectively. Driven by the hydraulic cylinder 22, the buffer rack 62 moves. The buffer rack 62 pushes the propulsion frame 21 to slide via the elastic buffer member 63, thereby driving the drill rod 23 and drill bit 24 to move. The motor 25 drives the drill rod 23 to rotate, enabling the drill bit 24 to drill holes in the tunnel wall, thus achieving the drilling function. Furthermore, the elastic buffer member 63 provides a buffering effect during the propulsion process of the propulsion frame 21, preventing damage to the drilling mechanism 2 due to excessive impact force, thereby extending the service life of the drilling mechanism 2 and improving the stability and safety of the drilling operation.

[0033] Reference Figure 5 The buffer frame 62 is also provided with a distance sensor 64, which is generally a laser distance sensor 64 and is used to detect the relative distance from the propulsion frame 21. A hammer 65 is slidably mounted on the buffer frame 62, and a drive unit 66 is used to drive the hammer 65 to slide. The drive unit 66 can be a hydraulic pump, whose cylinder is fixed to the buffer frame 62 and whose piston rod is connected to the hammer 65. A receiving block 211 is fixedly mounted on the propulsion frame 21. The distance sensor 64 is electrically connected to a controller, which is electrically connected to the drive unit 66. When the drill bit 24 encounters an obstruction or abnormality that prevents the propulsion frame 21 from advancing normally, the relative distance between the propulsion frame 21 and the buffer frame 62 gradually decreases. When the distance sensor 64 detects that the relative distance between the buffer frame 62 and the propulsion frame 21 reaches a set value, the controller controls the drive unit 66 to drive the hammer 65 to slide and strike the receiving block 211 on the propulsion frame 21, providing additional excitation force to the propulsion frame 21, breaking up the obstruction, ensuring normal drilling operation, and improving drilling efficiency and the adaptability of the device. Furthermore, an electromagnetic push rod may be used as the drive unit 66 instead of the hydraulic pump.

[0034] The implementation principle of the excavation construction device of a hydraulic tunnel drilling trolley 1 in the embodiment of the present application is as follows: the trolley 1 can be flexibly moved by the walking wheels 11 at the bottom of the trolley 1; the lifting component drives the lifting frame 3 to rise and fall, which can adjust the height of the punching mechanism 2; the first driving member 32 drives the moving frame 4 to slide, which can change the horizontal position of the punching mechanism 2; the driving motor 42 drives the support arm 5 to rotate, and further adjusts the position of the punching mechanism 2; the driving component drives the mounting frame 6 to rotate, which can adjust the angle of the punching mechanism 2; so that the punching mechanism 2 can accurately perform drilling operations at different positions and angles of the tunnel wall in a complex and changeable hydraulic tunnel construction environment, thereby meeting the drilling requirements at different positions and angles of the tunnel, while ensuring the drilling efficiency and accuracy, and effectively reducing the labor intensity of workers.
