Description

Technical Field

[0001] The invention relates to the technical field of support, and in particular to a stable support device for mine tunnel construction. Background Art

[0002] Support equipment plays a vital role in maintaining the structural stability of the tunnel. It can withstand the pressure from the tunnel surrounding rock and evenly transfer the pressure to the surrounding strata to prevent the tunnel from deformation, cracking and other problems. A stable tunnel structure is not only conducive to the smooth progress of construction, but also ensures the safety and durability of the tunnel after it is put into use.

[0003] At present, in the existing technology, stable support equipment is a key factor in ensuring the safety of construction workers during mine tunnel construction. The geological conditions inside the tunnel are complex and changeable, and there may be rock crushing, unstable strata, etc. Although traditional steel arch support equipment can withstand a certain amount of surrounding rock pressure, it has limited protection against emergencies such as rock falling and small-scale collapse. Moreover, the protective structure of these equipment is usually fixed and cannot be flexibly adjusted according to actual needs during the construction process. In tunnel construction, the geological conditions and construction risks in different sections may be different, and protective equipment needs to be able to adapt to changes in a timely manner. Summary of the invention

[0004] The main purpose of the present invention is to provide a stable support device for mine tunnel construction, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention proposes a stable support device for mine tunnel construction, comprising a support base, the outer wall of the support base is provided with a rotation protection device, the rotation protection device is movably connected to an auxiliary support device through a linkage assembly, the support base is rotatably connected to a support frame, and the rotation protection device comprises:

[0006] An annular support seat, the outer wall of the support base is fixedly connected to the annular support seat, the outer wall of the annular support seat is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to a connecting rod;

[0007] The rotating disk, the connecting rod passes through the annular support seat and is fixedly connected to the rotating disk, the surface of the rotating disk is provided with an arc groove, and a sleeve block is sleeved in the arc groove;

[0008] The sliding block is fixedly connected to the sleeve block, the sliding block is fixedly connected to a protective plate, and the sliding block is slidably connected to the annular support seat.

[0009] Preferably, the linkage assembly includes a transmission wheel 1, the connecting rod is fixedly connected to the transmission wheel 1, and the motor output shaft drives the connecting rod to rotate.

[0010] Preferably, the transmission wheel 1 is connected to the transmission wheel 2 through a transmission belt, and the transmission wheel 2 is rotatably connected to the fixed plate. The transmission wheel 1 transmits power to the transmission wheel 2 through the transmission belt, and the transmission wheel 2 rotates accordingly.

[0011] Preferably, the transmission wheel 2 is fixedly connected to a rotating shaft, the rotating shaft is fixedly connected to gear 1, and gear 1 is meshingly connected to gear 2. The rotation of the transmission wheel 2 drives the rotating shaft to rotate, and the rotating shaft then rotates gear 1, and gear 2 rotates under the drive of gear 1.

[0012] Preferably, the second gear is fixedly connected to the first end face ratchet, the first end face ratchet is meshingly connected to the second end face ratchet, and the second end face ratchet is elastically connected to the rotating ring via a spring.

[0013] Preferably, the end face ratchet wheel 2 is fixedly connected to a rotating rod, and the rotating rod is rotatably connected to a rotating ring. When the end face ratchet wheel 1 rotates forward, it drives the end face ratchet wheel 2 meshed therewith to rotate. The end face ratchet wheel 2 is connected to the rotating ring through the rotating rod, and the rotating rod rotates in the rotating ring. The spring provides an elastic connection to ensure the stability of the end face ratchet wheel 2 during the rotation process. When the end face ratchet wheel 1 rotates in the reverse direction, due to the unidirectional characteristics of the ratchet mechanism, the end face ratchet wheel 2 will not rotate with it, thereby realizing a unidirectional transmission function.

[0014] Preferably, the auxiliary support device includes a storage belt, and the rotating rod is fixedly connected to the storage belt. When the rotating protection device is working, the support frames on both sides also rotate synchronously, thereby stretching the storage belt to prevent the gravel on both sides of the mine tunnel from damaging the equipment.

[0015] Preferably, one end of the storage belt away from the rotating rod is fixedly connected to a horizontal plate, both ends of the horizontal plate are fixedly connected to support plates, and the support plates are fixedly connected to the support frame. When the end face ratchet wheel 1 rotates forward, the end face ratchet wheel 2 is driven to rotate, and then the rotating rod starts to rotate, and the rotating rod realizes the stretching and retraction of the storage belt.

[0016] Preferably, the transverse plate is rotatably connected to hinged plate 1, and hinged plate 1 is hinged to hinged plate 2. When the transverse plate rotates with the support frame, the angles of hinged plate 1 and hinged plate 2 are adjusted and contracted.

[0017] Preferably, the end of the hinged plate 2 away from the hinged plate 1 is rotatably connected to the connecting plate, and the connecting plate is fixedly connected to the fixed plate. The hinged plate 1 and the hinged plate 2 are used to effectively protect and support both sides of the tunnel, thereby reducing the number of equipment and the complexity of construction and improving construction efficiency.

[0018] The present invention provides a stable support device for mine tunnel construction. It has the following beneficial effects:

[0019] (1) The stable support equipment for mine tunnel construction starts the motor through the rotating protection device, drives the connecting rod to rotate, and the connecting rod then rotates the rotating disk. As the rotating disk rotates, the sleeve block moves in the arc groove, and the movement of the sleeve block drives the sliding block to slide on the annular support seat. The sliding of the sliding block drives the movement of the protective plate, thereby realizing the deployment or folding of the protective plate. During the construction process, when it is necessary to support and protect the tunnel, the protective plate can be deployed to effectively prevent accidents such as rock falling and collapse from causing harm to construction personnel and equipment. When protection is not needed, the protective plate can be folded to reduce the space occupied by the equipment and facilitate the movement and operation of the equipment.

[0020] (2) The stable support equipment for mine tunnel construction is provided with a linkage assembly. When the motor output shaft drives the connecting rod to rotate, the transmission wheel 1 transmits power to the transmission wheel 2 through the transmission belt. The rotation of the transmission wheel 2 drives the rotating shaft to rotate, and the rotating shaft then causes the gear 1 to rotate. The rotation of the transmission wheel 2 drives the rotating shaft to rotate, and the rotating shaft then causes the gear 1 to rotate. The gear 2 rotates under the drive of the gear 1. The rotating rod rotates in the rotating ring. The spring provides an elastic connection. When the end face ratchet wheel 1 rotates in the opposite direction, the end face ratchet wheel 2 will not rotate with it, thereby realizing a one-way transmission function. In the stable support equipment for mine tunnel construction, this one-way transmission can prevent certain components from rotating or moving unnecessarily when subjected to reverse force, thereby ensuring the stability and safety of the equipment during operation.

[0021] (3) The stable support equipment for the mine tunnel construction is equipped with an auxiliary support device. When the end ratchet wheel 1 rotates in the forward direction, it drives the end ratchet wheel 2 to rotate, and then the rotating rod starts to rotate. The rotating rod realizes the stretching and retraction of the storage belt. When the rotating protection device is working, the support frames on both sides also rotate synchronously, and the storage belt is stretched to prevent the gravel on both sides of the mine tunnel from damaging the equipment. When the cross plate rotates with the support frame, it drives the angle adjustment and contraction of the hinged plate 1 and the hinged plate 2. The two sides of the tunnel are effectively protected and supported by the hinged plate 1 and the hinged plate 2, which reduces the number of equipment and the complexity of construction, and improves the construction efficiency.

The surface of the rotating disk 24 is provided with an arc groove 25, and a socket block 26 is sleeved in the arc groove 25. The connecting rod 23 then causes the rotating disk 24 to rotate. The arc groove 25 on the surface of the rotating disk 24 is sleeved with a socket block 26. The sleeve block 26 moves in the arc groove 25 as the rotating disk 24 rotates. The sleeve block 26 is fixedly connected to the sliding block 27. The sliding block 27 is fixedly connected to the protective plate 28. The sliding block 27 is slidably connected to the annular support seat 21. The movement of the sleeve block 26 drives the sliding block 27 to slide on the annular support seat 21. The sliding of the sliding block 27 drives the protective plate 28 to move, thereby realizing the deployment or folding of the protective plate 28. During the construction process, when it is necessary to support and protect the tunnel, the protective plate 28 can be deployed to effectively prevent accidents such as rock falling and collapse from causing harm to construction personnel and equipment. When protection is not needed, the protective plate 28 can be folded to reduce the space occupied by the equipment and facilitate the movement and operation of the equipment.

[0038] In the embodiment of the present invention, in order to provide stable and efficient transmission and ensure the stability and safety of the equipment during operation, the linkage assembly 3 includes a transmission wheel 1 31, a connecting rod 23 is fixedly connected to the transmission wheel 1 31, the output shaft of the motor 22 drives the connecting rod 23 to rotate, the transmission wheel 1 31 is transmission-connected to the transmission wheel 2 33 through a transmission belt 32, the transmission wheel 2 33 is rotationally connected to the fixed plate 34, the transmission wheel 1 31 transmits power to the transmission wheel 2 33 through the transmission belt 32, and the transmission wheel 2 33 rotates accordingly, the transmission wheel 2 33 is fixedly connected to a rotating shaft 35, and the rotating shaft 35 is fixedly connected to the gear 1 36 , gear one 36 is meshedly connected with gear two 37, the rotation of transmission wheel two 33 drives the rotating shaft 35 to rotate, and the rotating shaft 35 then causes gear one 36 to rotate, and gear two 37 rotates under the drive of gear one 36, and gear two 37 is fixedly connected with end face ratchet one 38, and end face ratchet one 38 is meshedly connected with end face ratchet two 39, and end face ratchet two 39 is elastically connected with the rotating ring 311 through a spring 310, and end face ratchet two 39 is fixedly connected with a rotating rod 312, and the rotating rod 312 is rotatably connected with the rotating ring 311, and when the end face ratchet one 38 rotates forward, it will drive the end face ratchet two 39 meshed with it to rotate. The end face ratchet 2 39 is connected to the rotating ring 311 through a rotating rod 312. The rotating rod 312 rotates in the rotating ring 311. The spring 310 provides an elastic connection to ensure the stability of the end face ratchet 2 39 during the rotation process. When the end face ratchet 1 38 rotates in the opposite direction, due to the unidirectional characteristics of the ratchet mechanism, the end face ratchet 2 39 will not rotate with it, thereby realizing a unidirectional transmission function. In the stable support equipment for mine tunnel construction, this unidirectional transmission can prevent certain components from rotating or moving unnecessarily when subjected to reverse force, thereby ensuring the stability and safety of the equipment during operation.

[0039] In the embodiment of the present invention, in order to effectively protect and support both sides of the tunnel and improve the construction efficiency, the auxiliary support device 4 includes a storage belt 41, and the rotating rod 312 is fixedly connected to the storage belt 41. When the rotating protection device 2 is working, the support frames 5 on both sides also rotate synchronously, and the storage belt 41 is stretched to prevent the gravel on both sides of the mine tunnel from damaging the equipment. The end of the storage belt 41 away from the rotating rod 312 is fixedly connected to a cross plate 42, and the two ends of the cross plate 42 are fixedly connected to support plates 43. The support plate 43 is fixedly connected to the support frame 5. When the end face ratchet 1 38 rotates forward, it drives the end face ratchet 2 39 The rotating rod 312 starts to rotate, and the rotating rod 312 realizes the stretching and retracting of the storage belt 41. The horizontal plate 42 is rotatably connected to the hinged plate 1 44, and the hinged plate 1 44 is hinged to the hinged plate 2 45. As the support frame 5 rotates, the horizontal plate 42 drives the angle of the hinged plate 1 44 and the hinged plate 2 45 to adjust and shrink. The end of the hinged plate 2 45 away from the hinged plate 1 44 is rotatably connected to the connecting plate 46, and the connecting plate 46 is fixedly connected to the fixed plate 34. Through the hinged plate 1 44 and the hinged plate 2 45, the two sides of the tunnel are effectively protected and supported, which reduces the number of equipment and the complexity of construction, and improves the construction efficiency.

[0040] In the present invention, when in use, the motor 22 is started, and its output shaft drives the connecting rod 23 to rotate, and the connecting rod 23 then rotates the rotating disk 24. A socket block 26 is sleeved in the arc groove 25 on the surface of the rotating disk 24. As the rotating disk 24 rotates, the socket block 26 moves in the arc groove 25. The movement of the socket block 26 drives the sliding block 27 to slide on the annular support seat 21. The sliding of the sliding block 27 drives the protective plate 28 to move, thereby realizing the deployment or retraction of the protective plate 28. During the construction process, when it is necessary to support and protect the tunnel, the protective plate 28 can be deployed to effectively prevent accidents such as rock falling and collapse from causing harm to construction personnel and equipment. When protection is not needed, the protective plate 28 can be folded to reduce the space occupied by the equipment and facilitate the movement and operation of the equipment. While the output shaft of the motor 22 drives the connecting rod 23 to rotate, the transmission wheel 1 31 transmits power to the transmission wheel 2 33 through the transmission belt 32, and the transmission wheel 2 33 rotates accordingly. The rotation of the transmission wheel 2 33 drives the rotating shaft 35 to rotate, and the rotating shaft 35 then rotates the gear 1 36. The gear 2 37 rotates under the drive of the gear 1 36. When the end face ratchet 1 38 rotates forward, it drives the end face ratchet 2 39 meshing with it to rotate. The end face ratchet wheel 39 is connected to the rotating ring 311 through the rotating rod 312. The rotating rod 312 rotates in the rotating ring 311. The spring 310 provides an elastic connection to ensure the stability of the end face ratchet wheel 39 during the rotation process. When the end face ratchet wheel 1 38 rotates forward, it drives the end face ratchet wheel 39 to rotate, and then the rotating rod 312 starts to rotate. The rotating rod 312 realizes the stretching and retracting of the storage belt 41. When the rotating protection device 2 is working, the support frames 5 on both sides also rotate synchronously, and the storage belt 41 is stretched to prevent the gravel on both sides of the mine tunnel from damaging the equipment. When the cross plate 42 rotates with the support frame 5, it drives the angle adjustment and contraction of the hinged plate 1 44 and the hinged plate 2 45. 5 provides effective protection and support for both sides of the tunnel, reduces the number of equipment and the complexity of construction, and improves construction efficiency. When the motor 22 reverses, it drives the protective plate 28 to fold, and indirectly drives the end ratchet 1 38 to rotate in the opposite direction through the transmission wheel 1 31, the transmission belt 32 and the transmission wheel 2 33. During the retraction of the support frame 5, the storage belt 41 is rolled up, and the hinge plate 1 44 and the hinge plate 2 45 shrink inward. Due to the unidirectional characteristics of the ratchet mechanism, the end ratchet 2 39 will not rotate with it, thereby realizing the unidirectional transmission function. In the stable support equipment for mine tunnel construction, this unidirectional transmission can prevent certain components from rotating or moving unnecessarily when subjected to reverse force, thereby ensuring the stability and safety of the equipment during operation.
