Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction technology and relates to a rock breaking device for tunnel construction. Background Technology

[0002] During tunnel construction, it is often necessary to break up the rock on the tunnel walls and create openings. Traditional rock breaking methods typically rely on manual labor using simple tools such as hammers and chisels. This method is not only inefficient but also physically demanding, significantly impacting the health of construction workers. With technological advancements, mechanized rock breaking equipment has been introduced into tunnel construction. However, this equipment often suffers from limitations such as limited functionality, complex operation, and high maintenance costs.

[0003] Specifically, most existing rock breaking equipment can only perform single crushing or cutting operations, and cannot simultaneously perform circumferential cutting and crushing. In tunnel construction, it is usually necessary to first circumferentially cut the rock to create a hole, and then crush the rock inside the hole to facilitate subsequent support or installation work. Existing equipment requires the use of different tools or equipment to complete these two steps, which not only increases construction costs and time, but also reduces construction efficiency. Utility Model Content

[0004] In view of this, in order to solve the problem that most existing rock crushing equipment can only perform single crushing or cutting operations and cannot simultaneously achieve the functions of circumferential cutting and crushing, this utility model provides a rock crushing device for tunnel construction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rock breaking device for tunnel construction, comprising:

[0006] The equipment housing has a soft cushion fixedly installed on one side, and a handle ring fixedly installed on the equipment housing;

[0007] The power mechanism is installed inside the equipment housing. The power mechanism includes a fixed plate and a drive motor. The fixed plate is fixedly installed inside the equipment housing, and the drive motor is fixedly installed on one side of the fixed plate.

[0008] A rotating ring, connected to the power mechanism, extends on one side to the outside of the equipment housing, and is rotatably connected to the inner wall of the equipment housing;

[0009] A ring-cutting mechanism, installed on one side of a rotating ring, is used to cut rocks to create holes;

[0010] The vibratory crushing mechanism is connected to the power mechanism. One side of it extends to the outside of the equipment housing and is connected to the ring cutting mechanism. It is used to crush the rock inside the cut hole.

[0011] The hydraulic mechanism is located on the outside of the equipment housing, with one side extending into the equipment housing and connected to the vibratory crushing mechanism, and is used to drive the vibratory crushing mechanism to move.

[0012] The drive motor is started to drive the power mechanism to run, which drives the rotating ring to rotate, thereby driving the ring cutting mechanism to cut the rock inside the tunnel to form holes. The hydraulic mechanism drives the vibration crushing mechanism to crush the rock inside the holes.

[0013] Furthermore, the power mechanism also includes a gear assembly, which includes a drive gear fixedly mounted on the output shaft of the drive motor via a key connection. A toothed ring is welded to the inner wall of the rotating ring, and the drive gear meshes with the toothed ring. When the drive motor is started, it drives the drive gear to rotate, and through the meshing transmission with the toothed ring, it drives the rotating ring to rotate, thereby driving the ring cutting mechanism to operate.

[0014] Furthermore, the circumferential cutting mechanism includes multiple buffer bars, connecting rings, and mounting rings. Multiple buffer bars are installed at equal intervals on one side of the rotating ring, and one end of each is connected to the same connecting ring. Multiple clamping plates are fixedly installed at equal intervals on one side of the connecting ring, and multiple clamping holes are opened at equal intervals on the mounting ring. The clamping plates are movably clamped to the corresponding clamping holes. A circumferential cutting blade is welded to one side of the mounting ring. The circumferential cutting blade is installed by clamping the mounting ring to the connecting ring through the clamping plates. When the rotating ring rotates, the buffer bars drive the connecting ring to rotate, thereby driving the circumferential cutting blade to circumferentially cut the rock on the inner wall of the tunnel.

[0015] Furthermore, the buffer rod includes a limiting tube fixedly installed on one side of the rotating ring. A support rod is slidably connected inside the limiting tube. One end of the support rod extends to the outside of the limiting tube and is welded to the connecting ring. A compression spring located outside the limiting tube is sleeved on the support rod. The two ends of the compression spring are fixedly connected to one end of the limiting tube and one end of the connecting ring, respectively. A rubber pad is fixedly installed inside the limiting tube. The other end of the support rod is bonded to one side of the rubber pad. The rubber pad and compression spring provide elastic support for the connecting ring, buffering and protecting it during ring cutting, and reducing the transmission of vibration to the equipment housing.

[0016] Furthermore, multiple rotating rods are rotatably connected at equal intervals on the mounting ring. One end of each rotating rod extends to one side of the connecting ring and is welded with a baffle. The baffle contacts one side of the connecting ring. A torsion spring is fitted on the rotating rod, and both ends of the torsion spring are fixedly connected to one side of the mounting ring and the other end of the rotating rod, respectively. After the mounting ring is engaged with the retaining plate, the rotating rod is released, and the torsion spring drives the rotating rod to rotate, causing the baffle to contact the connecting ring and limit and fix the mounting ring.

[0017] Furthermore, the vibration crushing mechanism includes multiple mounting rods, a mounting plate, a transmission box, a transmission plate, a push rod, and a hammer assembly. Multiple mounting rods are fixedly installed at equal intervals on one side of the fixed plate, with one end extending into the rotating ring and fixedly mounted on the same mounting plate. The mounting plate is rotatably connected to the inner wall of the rotating ring. A transmission box is fixedly installed on one side of the mounting plate, and a transmission plate is slidably connected within the transmission box. A push rod is fixedly installed on one side of the transmission plate, with one end penetrating the inner wall of one side of the transmission box and extending to the outer side. The push rod is tightly slidably connected to the inner wall of one side of the transmission box. A hydraulic mechanism is connected to the transmission box. Activating the hydraulic mechanism adjusts the hydraulic oil volume on both sides of the transmission plate, driving the transmission plate to reciprocate laterally within the transmission box. The push rod then drives the hammer assembly to hammer and crush the rock within the circumferential cutting hole.

[0018] Furthermore, the hammer assembly includes a connecting frame rotatably connected to one end of the push rod. The connecting frame is slidably sleeved on multiple limiting tubes. A vibrating hammer is fixedly installed at the center of one side of the connecting frame, and multiple crushing teeth are welded at equal intervals on one side of the vibrating hammer. The connecting frame moves laterally and reciprocally under the drive of the push rod, causing the vibrating hammer to vibrate. At the same time, the connecting frame rotates with the limiting tubes, causing the vibrating hammer to rotate. When the rock is crushed by vibration, shearing force is generated, which facilitates the crushing of the rock.

[0019] Furthermore, the hydraulic mechanism includes a power box and a push assembly. The power box contains hydraulic oil, and a first hose and a second hose are fixedly installed on the inner walls of both sides of the power box, respectively. A first flow pipe and a second flow pipe are fixedly installed at the top ends of the first hose and the second hose, respectively. The top end of the first flow pipe extends into the transmission box and is fixedly connected to one side of the inner wall. The top end of the second flow pipe penetrates the equipment housing and extends into the transmission box, and is fixedly connected to the other side of the inner wall. Both the first flow pipe and the second flow pipe penetrate the fixed plate and the mounting plate. When the push assembly is activated, the hydraulic oil in the power box is delivered to the first hose or the second hose, and then delivered to both sides of the transmission plate in the transmission box through the first flow pipe and the second flow pipe, causing the transmission plate to move laterally reciprocating, driving the vibratory hammer to vibrate and break the rock.

[0020] Furthermore, the driving component includes a piston plate that is sealed and slidably connected within the power box. Hydraulic oil is provided on both sides of the piston plate. A piston rod is fixedly installed on one side of the piston plate. One end of the piston rod penetrates the inner wall of one side of the power box and extends to the outer side. An electric push rod is fixedly installed on the top of the power box. The output shaft of the electric push rod extends to one side of the power box and is fixedly installed with a connecting arm. One end of the piston rod is fixedly connected to the bottom of one side of the connecting arm. The piston rod is tightly slidably connected to the inner wall of one side of the power box. When the electric push rod is activated, it drives the connecting arm to reciprocate laterally. The piston rod drives the piston plate to reciprocate laterally within the power box, causing the hydraulic oil to flow between the power box and the transmission box, thereby driving the vibratory hammer to vibrate.

[0021] Furthermore, the rotating ring is rotatably connected to the inner wall of the equipment housing via bearings, the transmission plate and the transmission box are connected by a sealed sliding fit, and the support rod and the limit tube are slidably connected to ensure the stable operation and functional realization of each component.

[0024] 2. The rock breaking device for tunnel construction disclosed in this utility model, through the ring cutting mechanism, can install the ring cutting blade by clamping the installation ring with the connecting ring through multiple clamping plates. Then, when the rotating ring is kept rotating, the connecting ring can be driven to rotate through multiple buffer bars. At this time, the ring cutting blade can be driven to rotate. The rotating ring cutting blade can perform ring cutting on the rock of the tunnel inner wall to achieve the purpose of opening holes in the tunnel inner wall.

[0025] 3. The rock crushing device for tunnel construction disclosed in this utility model has a vibration crushing mechanism. The hydraulic oil volume on both sides of the transmission plate can be adjusted by starting the hydraulic mechanism, so as to drive the transmission plate to move laterally back and forth in the transmission box.

[0026] 4.

[0038] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] In one embodiment: such as Figure 1-8 The crushing device shown includes a housing 1. A soft cushion 2 is bolted to one side of the housing 1, and a handle ring 3 is welded to the housing 1 for easy hand operation. A power mechanism is installed inside the housing 1, including a fixing plate 4 fixedly installed inside the housing 1. A drive motor 5 is bolted to one side of the fixing plate 4, and the output shaft of the drive motor 5 extends into a rotating ring 6 and is connected to a gear assembly. One side of the rotating ring 6 extends to the outside of the housing 1 and is rotatably connected to the inner wall of the housing 1 via a bearing, ensuring stable rotation of the rotating ring 6.

[0040] The gear assembly includes a drive gear 8 fixedly mounted on the output shaft of the drive motor 5 via a key connection, and a gear ring 7 welded to the inner wall of the rotating ring 6. The drive gear 8 meshes with the gear ring 7. When the drive motor 5 is started, the drive gear 8 rotates accordingly, and through the meshing transmission action with the gear ring 7, it drives the rotating ring 6 to rotate.

[0041] A ring-cutting mechanism is installed on one side of the rotating ring 6. The ring-cutting mechanism includes multiple buffer bars evenly spaced on one side of the rotating ring 6. Each buffer bar includes a limiting tube 9 fixedly installed on one side of the rotating ring 6. A support rod 10 is slidably connected inside the limiting tube 9. One end of the support rod 10 extends to the outside of the limiting tube 9 and is welded to a connecting ring 11. A compression spring 12 is sleeved on the support rod 10, located outside the limiting tube 9. Both ends of the compression spring 12 are fixedly connected to one end of the limiting tube 9 and one side of the connecting ring 11 respectively via hooks. A rubber pad 13 is fixedly installed inside the limiting tube 9. The other end of the support rod 10 is glued to one side of the rubber pad 13. The elastic force of the rubber pad 13 and the compression spring 12 provides elastic support for the connecting ring 11, thereby providing buffer protection when the ring-cutting blade 15 cuts the tunnel inner wall.

[0042] Multiple clamping plates 16 are fixedly installed at equal intervals on one side of the connecting ring 11, and an installation ring 14 is also included. The installation ring 14 has multiple clamping holes at equal intervals, and the clamping plates 16 are movably engaged with the corresponding clamping holes. A ring cutter 15 is welded to one side of the installation ring 14. The ring cutter 15 is used to rotary cut the rock on the tunnel wall. After the installation ring 14 is engaged with the connecting ring 11 via the multiple clamping plates 16, the installation of the ring cutter 15 is complete. When the rotating ring 6 rotates, multiple buffer bars drive the connecting ring 11 to rotate, which in turn drives the ring cutter 15 to rotate, circumferentially cutting the rock on the tunnel wall to form the required holes.

[0043] Multiple rotating rods 17 are rotatably connected at equal intervals through the mounting ring 14. One end of each rotating rod 17 extends to one side of the connecting ring 11 and is welded with a baffle 18, which contacts one side of the connecting ring 11. A torsion spring 19 is fitted onto each rotating rod 17, and both ends of the torsion spring 19 are fixedly connected to one side of the mounting ring 14 and the other end of the rotating rod 17 by bolts. After the mounting ring 14 is engaged with the multiple retaining plates 16, the rotating rods 17 are released. The torsion spring 19, under stress, drives the rotating rods 17 to rotate, moving the baffle 18 to a position that contacts one side of the connecting ring 11, thereby limiting the mounting ring 14 and ensuring stable installation of the mounting ring 14 and the connecting ring 11.

[0044] The device also includes a vibration crushing mechanism connected to the power mechanism. The vibration crushing mechanism includes multiple mounting rods 20 that are fixedly installed at equal intervals on one side of the fixed plate 4. One end of each mounting rod 20 extends into the rotating ring 6 and is fixedly mounted on the same mounting plate 21. The mounting plate 21 is rotatably connected to the inner wall of the rotating ring 6 via bearings. A transmission box 22 is fixedly mounted on one side of the mounting plate 21. A transmission plate 23 is slidably connected inside the transmission box 22. A push rod 24 is fixedly mounted on one side of the transmission plate 23. One end of the push rod 24 passes through the inner wall of one side of the transmission box 22 and extends to the outer side of the transmission box 22. The push rod 24 is tightly slidably connected to the inner wall of one side of the transmission box 22.

[0045] A hammer assembly is connected to one end of the push rod 24. The hammer assembly includes a connecting frame 25 rotatably connected to one end of the push rod 24, and the connecting frame 25 is slidably sleeved on multiple limiting tubes 9. A vibrating hammer 26 is fixedly installed at the center of one side of the connecting frame 25, and multiple crushing teeth 27 are welded at equal intervals on one side of the vibrating hammer 26. When the connecting frame 25 receives the power transmitted by the push rod 24, it vibrates the vibrating hammer 26 as the push rod 24 performs lateral reciprocating motion. At the same time, the connecting frame 25 can rotate with the multiple limiting tubes 9, driving the vibrating hammer 26 to rotate, so that the vibrating hammer 26 generates shear force while vibrating and crushing the rock, which facilitates the crushing of the rock.

[0046] This application can be used in the field of building construction technology, or in other fields applicable to this application.

[0047] refer to Figure 3 and Figure 8 A rock breaking device for tunnel construction, applied in the field of building construction technology, includes a hydraulic mechanism located outside the equipment housing 1. The hydraulic mechanism includes a power box 32 containing hydraulic oil. A first hose 30 and a second hose 31 are fixedly installed on the inner walls of both sides of the power box 32. A first flow pipe 28 and a second flow pipe 29 are fixedly installed at the top ends of the first hose 30 and the second hose 31, respectively. The top end of the first flow pipe 28 extends into a transmission box 22 and is fixedly connected to one inner wall of the transmission box 22. The top end of the second flow pipe 29 penetrates the equipment housing 1 and extends into the transmission box 22, and is fixedly connected to the other inner wall of the transmission box 22. Both the first flow pipe 28 and the second flow pipe 29 penetrate a fixing plate 4 and a mounting plate 21.

[0048] A pushing assembly is installed inside the power box 32. The pushing assembly includes a piston plate 36 that is slidably and sealed within the power box 32. Hydraulic oil is provided on both sides of the piston plate 36. A piston rod 35 is fixedly installed on one side of the piston plate 36. One end of the piston rod 35 passes through the inner wall of one side of the power box 32 and extends to the outer side of the power box 32. An electric push rod 33 is fixedly installed on the top of the power box 32. The output shaft of the electric push rod 33 extends to one side of the power box 32 and is fixedly installed with a connecting arm 34. One end of the piston rod 35 is fixedly connected to the bottom side of the connecting arm 34, and the piston rod 35 is tightly slidably connected to the inner wall of one side of the power box 32.

[0049] When the electric push rod 33 is activated, it drives the connecting arm 34 to reciprocate laterally, which in turn drives the piston plate 36 to reciprocate laterally within the power box 32 via the piston rod 35. When the piston plate 36 approaches the first hose 30 or the second hose 31, hydraulic oil is output from either hose, flows through the first flow pipe 28 or the second flow pipe 29 to the transmission box 22, and then flows to both sides of the transmission plate 23, causing the transmission plate 23 to reciprocate laterally, thereby driving the vibratory hammer 26 to vibrate and break the rock. When the transmission plate 23 moves to one side, the hydraulic oil in the same direction flows back into the power box 32, transmitting power through the hydraulic oil on both sides of the piston plate 36, facilitating the driving of the vibratory hammer 26.

[0050] First, rotate the rotating rod 17 to make the baffle 18 deviate from the side of the connecting ring 11. Then, align the multiple locking holes on the mounting ring 14 with the multiple locking plates 16 on the side of the connecting ring 11, and lock the mounting ring 14 to the connecting ring 11 through the multiple locking plates 16. After locking the mounting ring 14 to the multiple locking plates 16, release the rotating rod 17. The torsion spring 19, which is under force, drives the rotating rod 17 to rotate, moving the baffle 18 to contact the side of the connecting ring 11, limiting the mounting ring 14, and ensuring that the mounting ring 14 and the connecting ring 11 are stably installed. The installation of the ring cutter 15 is then completed. Next, start the drive motor 5. The output shaft of the drive motor 5 drives the drive gear 8 to rotate. 8 meshes with the toothed ring 7, and under the action of meshing transmission, drives the rotating ring 6 to rotate. When the rotating ring 6 rotates, it drives the connecting ring 11 to rotate through multiple buffer bars, which in turn drives the ring cutter 15 to rotate. The operator holds the handle ring 3 and aligns the ring cutter 15 with the position where a hole needs to be made in the inner wall of the tunnel. The rotating ring cutter 15 ring cuts the rock in the inner wall of the tunnel to form the required hole. During the ring cutting process, the rubber pad 13 provides elastic support to the support rod 10, and together with the elastic force of the compression spring 12, it provides elastic support to the connecting ring 11, thereby buffering and protecting the ring cutter 15, preventing the ring cutter 15 from being damaged by excessive pressure, and reducing the vibration transmitted to the equipment. The housing 1 is designed for easy handheld operation. The electric actuator 33 is activated, and its output shaft drives the connecting arm 34 in a lateral reciprocating motion. This, in turn, drives the piston plate 36 in a lateral reciprocating motion within the power box 32 via the piston rod 35. When the piston plate 36 approaches the first hose 30, hydraulic oil is output from the first hose 30, transported through the first flow pipe 28 to the transmission box 22, and flows to one side of the transmission plate 23. When the piston plate 36 approaches the second hose 31, hydraulic oil is output from the second hose 31, transported through the second flow pipe 29 to the transmission box 22, and flows to the other side of the transmission plate 23. By maintaining the lateral reciprocating motion of the piston plate 36, the hydraulic system can be adjusted... The hydraulic oil on both sides of the piston plate 36 drives the transmission plate 23 to reciprocate laterally within the transmission box 22. When the transmission plate 23 reciprocates laterally, it drives the connecting frame 25 to reciprocate laterally via the push rod 24, thereby causing the vibrating hammer 26 to vibrate. The connecting frame 25 rotates along with multiple limit tubes 9, causing the vibrating hammer 26 to rotate. This causes the vibrating hammer 26 to generate shear force while vibrating and crushing the rock in the circumferential hole, facilitating the crushing of the rock. When the transmission plate 23 moves to one side, the hydraulic oil in the same direction flows back into the power box 32. By continuously transmitting the hydraulic oil on both sides of the piston plate 36, the vibrating hammer 26 is driven to vibrate continuously, crushing the rock in the hole.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
