A multi-directional drilling rig for tunnels

Abstract

The present invention relates to the field of anchor bolt construction technology, and in particular to a multi-directional drilling rig for tunnels. The spacing between the slots of the present invention is just enough to accommodate the arrangement of the engaged rotating block. At the same time, the rotating block is tilted and engaged between two protrusions when not subjected to external force. Under the action of the gravity block, the rotating block will be tilted and engaged between the two protrusions. At this time, the rotating block and the telescopic rod of the component indirectly connected thereto will also be limited. This fixes the direction of the top end of the track, avoiding the problem that the direction of the top end of the track changes due to the movement of the drilling rig on the track. When the direction of the top end of the track needs to be changed, it is only necessary to drive the positioning device to rotate from top to bottom by the electric telescopic rod device to engage the slot with the rotating block. At this time, the rotating block overcomes the influence of the gravity block and breaks away from the engagement limit between the two protrusions. This enables the positioning device to move to adjust the direction of the top end of the track, thereby achieving stronger construction and environmental compatibility of the present invention.

Description

Technical Field

[0001] The present invention relates to the technical field of anchor rod construction, in particular to a multi-directional drilling rig for tunnels. Background Art

[0002] In modern coal mine anchor support operations, in order to reduce labor intensity, reduce safety hazards and improve excavation efficiency, anchor drilling rigs have been widely used in modern coal mine operations.

[0003] To meet the needs of all-around tunnel drilling operations, anchor bolters need to be able to rotate in multiple directions to support drilling at the top and both ends. However, existing anchor bolters often perform these support operations separately, requiring two sets of anchor bolters for each, increasing costs and taking up a large amount of space.

[0004] Therefore, improvements are made to the above problems. Summary of the Invention

[0005] Therefore, the present invention is made in view of the above problems. The present invention solves the problem of high operation cost and large volume occupied by multiple groups of existing devices through the design of telescopic rod movement and rotation. The present invention achieves the above objects through the following technical solutions:

[0006] The top of the movable frame is provided with a movable frame, and the movable frame is provided with a movable frame, and the movable frame is provided with a movable frame. The rotating block is fixedly connected to conical block one and conical block two; the conical block one faces the limiting device, and the conical block two faces the moving block; the end of the electric telescopic rod device is provided with a conical block three, and the extension rod of the electric telescopic rod device is provided with a slot; the limiting device includes a fixed block, a flat plate, an elastic telescopic rod two, a rack one, a protrusion one, a protrusion two, a gear one, a gear two, and a rack two; the flat plate is slidably connected to the bottom plate; the flat plate is slidably connected to the elastic telescopic rod two on the left side near one end of the electric telescopic rod device; a rack one and a protrusion two are respectively provided on the left and right sides of the flat plate; a fixed block is provided on the right side of the protrusion two; a protrusion one is provided on the top of the flat plate; the left side of the rack one is meshed with gear one, and the bottom of the gear one is fixedly connected with gear two; the gear two is meshed with rack two.

[0007] Preferably, the bottom of the electric telescopic rod device is movably connected to the base plate through a swing device.

[0008] Preferably, the rotating rod is threadedly connected to the connecting block.

[0009] Preferably, the top end of the telescopic rod is rotatably connected to the tail end of the track.

[0010] Preferably, a gravity block is provided on the side of the rotating clamping block close to the limiting device.

[0011] Preferably, the slot and the protrusion both match the rotating block.

[0012] Preferably, the fixed block and the second elastic telescopic rod are both fixedly connected to the base plate;

[0013] Preferably, gear 2 is rotationally connected to the base plate via a worm spring.

[0014] Beneficial effects

[0015] 1. The spacing between the card slots of the present invention can just accommodate the engagement of the rotating card block. At the same time, the rotating card block is tilted and engaged between the two protrusions when it is not subjected to external force. When the rotating card block is not subjected to external force, it will be tilted and engaged between the two protrusions due to the action of the gravity block. At this time, the rotating card block and the telescopic rod of the component indirectly connected to it will also be limited. This fixes the direction of the top of the track, avoiding the problem of the top of the track changing due to the movement of the drilling rig on the track. When the direction of the top of the track needs to be changed, it is only necessary to drive the positioning device from top to bottom by the electric telescopic rod device to engage the card slot with the rotating card block. At this time, the rotating card block overcomes the influence of the gravity block and breaks away from the engagement limit between the two protrusions. Figure 9 , which enables the positioning device to move and adjust the direction of the top of the track to achieve fine-tuning of the construction platform;

[0016] 2. In the present invention, the second gear is connected to the first gear and the rotation state is kept consistent. At the same time, the rack second is engaged with the second gear. After the second gear rotates, it can move relatively on the rack second. When it is necessary to move the position of the bottom plate to perform drilling operations at different positions of the top, it is only necessary to drive the positioning device horizontally toward the moving block by the electric telescopic rod device. Through the pushing effect of the conical block three, the protrusion two is separated from the fixed block limit. Figure 10 At the same time, the rack 1 is engaged with the gear 1, and the rotating block will also move with the protrusion 2 to break away from the engagement limit between the two protrusions 1. Figure 11 In this state, the electric telescopic rod device drives the positioning device to move horizontally, which can overcome the action of the worm spring of gear 2, so that gear 1 drives gear 2 to rotate and move on rack 2, thereby realizing the movement of the bottom plate to perform drilling operations at different positions of the top.

[0029] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that they can be easily implemented by a person skilled in the art. However, the present invention may be implemented in various forms and is not limited to the embodiments described below. In addition, components not relevant to the present invention may be omitted from the drawings to more clearly illustrate the present invention.

[0030] like Figure 1-3 As shown, a multi-directional drilling rig for tunnels includes: a base plate 1, a rotary drive device 2, a rotary rod 3, a connecting block 4, a track 5, a positioning device 6, an electric telescopic rod device 7, a swing device 8, a limit device 9, and a drilling rig 100;

[0031] The bottom plate 1 is slidably arranged on the limiting device 9;

[0032] The rotary drive device 2 is arranged on the base plate 1;

[0033] The rotating rod 3 is connected to the rotating driving device 2 and can rotate under the driving of the rotating rod 3;

[0034] The connecting block 4 is rotatably arranged on the rotating rod 3. In the specific implementation process, the connecting block 4 is rotatably connected to the track 5, and during the rotation of the rotating rod 3, the connecting block 4 can move up and down on the rotating rod 3;

[0035] The upper and lower ends of the positioning device 6 are connected to the track 5 and the bottom plate 1 respectively, and the positioning device 6 is slidably arranged in the slideway on the bottom plate 1;

[0036] The electric telescopic rod device 7 is arranged on the swing device 8. In the specific implementation process, the electric telescopic rod device 7 can swing left and right under the drive of the swing device 8;

[0037] The swing device 8 is arranged on the bottom plate 1;

[0038] During the specific implementation process, after the position of the connecting block 4 on the rotating rod 3 is determined, the electric telescopic rod device 7 drives the positioning device 6 to move left and right, so that the positioning device 6 can automatically extend and shorten the operation to achieve the change of the different inclination directions of the top of the track 5;

[0039] The limiting devices 9 are arranged on the upper and lower sides of the base plate 1. In the specific implementation process, the electric telescopic rod device 7 is indirectly engaged with the limiting device 9 through the positioning device 6 to enable the base plate 1 to move left and right on the limiting device 9;

[0040] The drilling rig 100 is slidably arranged on the track 5;

[0041] When the top of the track 5 needs to be changed from tilted to vertically upward, it is only necessary to drive the positioning device 6 to move to the lower end of the connecting block 4 by the electric telescopic rod device 7 to realize the top of the track 5 facing vertically upward. Figure 8 , thus achieving multi-directional rotation to cope with the drilling support work at the top and both sides. At the same time, the entire process can be completed on the same device, without the need for two separate groups of anchor drilling rigs to perform support work on the top and both sides, which not only increases costs but also takes up a lot of space;

[0042] During the rotation of the rotating rod 3, the connecting block 4 can move up and down on the rotating rod 3, which further increases the operable working area of ​​the track 5.

[0043] like Figure 4 As shown, the positioning device 6 includes: a moving block 61, a telescopic rod 62, a rotating block 63, a gravity block 64, an elastic telescopic rod 1 65, a conical block 1 66, and a conical block 2 67;

[0044] The moving block 61 is slidably arranged on a horizontal slideway in the bottom plate 1;

[0045] The telescopic rod 62 is provided at the upper end of the moving block 61;

[0046] The rotating block 63 is in the shape of a rectangular strip and is rotatably arranged at the side end of the moving block 61 via a connecting rod;

[0047] The gravity block 64 is disposed on one side of the rotating block 63. The gravity block 64 is heavy, so that the rotating block 63 tilts toward the side with the gravity block 64.

[0048] The elastic telescopic rod 1 65 is provided at the side end of the moving block 61. During the specific implementation process, it is always in a stretched state, so it always has a driving force toward the moving block 61.

[0049] The conical block 1 66 and the conical block 2 67 are arranged opposite to each other and are both connected to the elastic telescopic rod 1 65. Under the influence of the elastic force of the elastic telescopic rod 1 65, the conical block 2 67 will be located at the front end of the moving block 61 when not subjected to external force.

[0050] like Figure 9 As shown, the electric telescopic rod device 7 has a slot 71 and a tapered block 72;

[0051] There are multiple slots 71 and the spacing between the slots 71 is just enough to accommodate the engaging rotating block 63, so that the moving states of the two can be kept consistent;

[0052] The tapered block 3 72 is located at the front end of the slot 71;

[0053] like Figure 5-7 As shown, the limiting device 9 includes: a fixed block 91, a flat plate 92, a second elastic telescopic rod 93, a rack 1 94, a protrusion 1 95, a second protrusion 96, a gear 1 97, a gear 2 98, and a rack 2 99;

[0054] The fixed block 91 is provided on the bottom plate 1;

[0055] The flat plate 92 is slidably disposed on the bottom plate 1. The flat plate 92 can move toward or away from the gear 1 97 along the elastic telescopic rod 2 93 on the bottom plate 1, and can also move forward and backward along the moving direction of the moving block 61.

[0056] The second elastic telescopic rod 93 is provided on the bottom plate 1, and the output end is slidably connected to the plate 92, and in the specific implementation process, it always has the driving force to drive the plate 92 to move toward the fixed block 91;

[0057] The rack 1 94 and a plurality of equally spaced protrusions 96 are located on opposite sides of the plate 92, with the rack 1 94 located near the side of the elastic telescopic rod 2 93. When no external force is applied, the protrusions 96 engage with the fixed block 91, preventing the plate 92 from moving.

[0058] The plurality of protrusions 95 are evenly spaced and located at the upper end of the flat plate 92. When the rotating block 63 is not subjected to external force, the rotating block 63 is tilted and engaged between two protrusions 95 by the action of the gravity block 64. At this time, the rotating block 63 and the telescopic rod 62 indirectly connected thereto are also limited. This fixes the direction of the top end of the track 5, avoiding the problem of the top end of the track 5 changing its direction when the drilling rig 100 moves on the slide groove.

[0059] At the same time, the top direction of the track 5 can be fixed, which also enables the drilling rig 100 to quickly move the track 5 up and down when drilling horizontal holes on both sides;

[0060] The gear 1 97 is rotatably mounted on the base plate 1 and can engage with the rack 1 94 and rotate under the drive of the rack 1 94. Under the driving force of the elastic telescopic rod 2 93, in the initial state, there is no engagement between the gear 1 97 and the rack 1 94 and a gap exists.

[0061] The second rack 99 is engaged with the second gear 98, and the second gear 98 can move relatively on the second rack 99 after rotating;

[0062] The rack 2 99 is fixed on the top of the construction platform;

[0063] The second gear 98 passes through the bottom plate 1 and is connected to the first gear 97. The rotation states of the two gears are consistent. A worm spring is provided at the connection position between the second gear 98 and the bottom of the bottom plate 1. When the worm spring disengages the first gear 97 from the rack 1 94, the second gear 98 can rotate relative to the second rack 99 to reset the bottom plate 1.

[0064] During the specific implementation process, when it is necessary to change the direction of the top of the track 5, the swing device 8 drives the electric telescopic rod device 7 to rotate upward by about a flat angle until the slot 71 presses down to the position of the rotating block 63. At this time, the rotating block 63 overcomes the influence of the gravity block 64 and presses down to the position where the slot 71 is located. The end of the rotating block 63 where the gravity block 64 is located is then lifted up and disengaged from the engagement limit between the two protrusions 95. Figure 9, so that the movement of the positioning device 6 is no longer blocked by the protrusion 95, and at the same time, the rotating block 63 is pressed down by the locking groove 71, and the moving states of the two are kept consistent; the electric telescopic rod device 7 can realize the movement of the telescopic rod 62 by driving the rotating block 63 to move, thereby adjusting the direction of the top end of the track 5. After the adjustment is completed, the swing device 8 drives the electric telescopic rod device 7 to rotate upward until the locking groove 71 disengages the rotating block 63. At this time, the rotating block 63 is affected by the gravity block 64 and is pressed down again in the direction of the protrusion 95 and is engaged between the two protrusions 95. At this time, the rotating block 63 and the telescopic rod 62 indirectly connected to it are also limited and kept stationary.

[0065] During the specific implementation process, when it is necessary to move the position of the base plate 1 to perform drilling operations at different positions on the top, the swing device 8 drives the electric telescopic rod device 7 to rotate upward at a flat angle until the electric telescopic rod device 7 is horizontally facing the moving block 61 and is located below the rotating clamping block 63; then the electric telescopic rod device 7 moves horizontally toward the moving block 61, and under the pushing effect of the conical block three 72 at the top of the electric telescopic rod device 7, the conical block two 67 overcomes the elastic force of the elastic telescopic rod one 65 and moves together with the conical block one 66 toward the direction of the protrusion two 96 and pushes the protrusion two 96 to break away from the fixed clamping block 91 and move toward the direction of the gear one 97. Figure 10 As the movement is completed, the rack 94 will engage with the gear 97, and the rotating block 63 will also move out of the engagement limit between the two protrusions 95 as the protrusion 95 moves. Figure 11 ;

[0066] In this state, the electric telescopic rod device 7 continues to move toward the moving block 61 and collides with the moving block 61, and then the moving state of the moving block 61 is transferred to the rotation state of the gear 1 97 through the engagement of the rack 1 94 and the gear 1 97, thereby realizing the movement of the bottom plate 1 to perform the drilling operation at different positions of the top.

[0067] When the position of the base plate 1 needs to be reset, the electric telescopic rod device 7 retracts, the rack 1 94 is no longer engaged with the gear 1 97, and the gear 2 98 rotates in the opposite direction under the action of the worm spring to achieve the reset of the position of the base plate 1;

[0068] Working principle of the present invention:

[0069] During the specific implementation process, when it is necessary to change the direction of the top of the track 5, the swing device 8 drives the electric telescopic rod device 7 to rotate upward by about a flat angle until the slot 71 presses down the position of the rotating block 63. At this time, the rotating block 63 overcomes the influence of the gravity block 64 and disengages the locking limit between the two protrusions 95. Figure 9, which makes the movement of the positioning device 6 no longer blocked by the protrusion 95, and at the same time, the rotating block 63 is pressed down by the card slot 71, and the moving states of the two are kept consistent; the electric telescopic rod device 7 can realize the movement of the telescopic rod 62 by driving the rotating block 63 to move, thereby adjusting the direction of the top end of the track 5; when the direction of the top end of the track 5 needs to be changed from inclined to vertically upward, it is only necessary to drive the positioning device 6 to the lower end of the connecting block 4 by the electric telescopic rod device 7 to realize the direction of the top end of the positioning device to be vertically upward. Figure 8 After the adjustment is completed, the swing device 8 drives the electric telescopic rod device 7 to rotate upward until the slot 71 is disengaged from the rotating block 63. At this time, the rotating block 63 is affected by the gravity block 64 and is pressed down again in the direction of the protrusion 95 and is engaged between the two protrusions 95. At this time, the rotating block 63 and the telescopic rod 62 indirectly connected to it are also limited and kept stationary. The adjustment of the top end of the track 5 is completed.

[0070] During the specific implementation process, when it is necessary to move the position of the base plate 1 to perform drilling operations at different positions of the top, the swing device 8 drives the electric telescopic rod device 7 to rotate upward at a flat angle until the electric telescopic rod device 7 is horizontally facing the moving block 61 and is located below the rotating clamping block 63; then the electric telescopic rod device 7 moves horizontally toward the moving block 61, and through the pushing effect of the tapered block three 72, the tapered block two 67 overcomes the elastic force of the elastic telescopic rod one 65 and moves together with the tapered block one 66 toward the protrusion two 96 and pushes the protrusion two 96 out of the fixed clamping block 91 limit. Figure 10 At the same time, the rack 94 and the gear 97 are engaged, and the rotating block 63 will also move with the protrusion 96 to disengage the engagement limit between the two protrusions 95. Figure 11 After that, the electric telescopic rod device 7 can overcome the effect of the worm spring at the connection position between the gear 2 98 and the bottom plate 1 always having the driving force effect of the gear 2 98 along the rack 2 99 toward the elastic telescopic rod 2 93, so that the gear 1 97 drives the gear 2 98 to rotate on the rack 2 99 in the opposite direction of the elastic telescopic rod 2 93, thereby realizing the movement of the bottom plate 1 to perform the drilling operation at different positions of the top;

[0071] When the position of the base plate 1 needs to be reset, the electric telescopic rod device 7 retracts, the rack 1 94 is no longer engaged with the gear 1 97, and the gear 2 98 rotates in the opposite direction under the action of the worm spring to achieve the reset of the position of the base plate 1.
