Technical Field
[0001] The present application relates to the technical field of anchor drilling rig components, and in particular to an anchor rod and cable drilling rig for geological disaster survey. Background Art
[0002] Anchor drilling rig (anchor cable drilling rig) is a kind of drilling and anchoring equipment widely used in various types of slope geological disaster prevention and control. It can be used for drilling operations in various complex strata and different drilling methods. It is recognized by the majority of construction units for its excellent drilling performance.
[0003] Among them, during the drilling construction of the existing anchor drilling rig, when adding an anchor rod, it is necessary to connect the front and rear anchor rods together by thread, and the pressure head on the propulsion mechanism cannot fix the newly added anchor rod in time, so that it will have a short idling action when rotating and pressing the anchor rod. Then, under the action of squeezing friction, the newly added anchor rod can be driven to rotate together and the two anchor rods are threaded together. As a result, during a drilling construction operation of the existing anchor drilling rig, the propulsion mechanism has a long period of ineffective work, which invisibly increases the energy consumption of the anchor drilling rig and greatly affects its drilling efficiency.
[0004] Therefore, there is an urgent need for a pressure head component used in the propulsion mechanism of an anchor drilling rig to solve the defects existing in the above-mentioned existing anchor drilling rigs during actual operation. Summary of the invention
[0005] The present application proposes an anchor rod and cable drilling rig for geological disaster survey, which has the ability to quickly form a card connection with a propulsion mechanism and transmit radial power when a new anchor rod is added, thereby effectively reducing the idling time of the propulsion mechanism thereon, avoiding ineffective work of the anchor drilling rig, and improving its drilling efficiency while reducing energy consumption. It is used to solve the problem that the existing anchor drilling rigs will have a short period of idling when rotating and pressing down the newly added anchor rod, which will cause the propulsion mechanism thereon to have a long period of ineffective work during a drilling operation.
[0006] To achieve the above object, the present application adopts the following technical solution: A rock bolt and cable anchor drilling rig for geological disaster survey, including a rock bolt and a pressure head member. A right trapezoidal groove is provided on the outer surface of the other end of the rock bolt; the pressure head member includes an inner ejector rod. A straight groove is provided on the outer surface of the inner ejector rod along the direction of its central axis, and an annular groove is provided in the middle of the outer surface of the inner ejector rod. An outer clamping sleeve is movably sleeved on one side of the outer surface of the inner ejector rod. The outer clamping sleeve includes a movable sleeve movably sleeved on the outer surface of the inner ejector rod. A claw corresponding to the right trapezoidal groove on the rock bolt is installed on the outer surface of the movable sleeve, and a limiting block is provided on the inner wall of the movable sleeve, and the limiting block is clamped with the straight groove on the inner ejector rod. The inner ejector rod and the outer clamping sleeve are connected by a spring movably sleeved on the annular groove, and a connecting sleeve rod is movably sleeved on the other side of the outer surface of the inner ejector rod through the straight groove thereon.
[0007] Further, an external thread is provided on the outer surface of one end of the rock bolt, and an internal thread matching the external thread is provided on the inner wall of the other end of the rock bolt.
[0008] Further, the end of the claw is provided with a right trapezoidal structure corresponding to the right trapezoidal groove, and the length of the wide side of the trapezoidal structure of the claw is less than the length of the narrow side of the right trapezoidal groove.
[0009] Further, when the outer clamping sleeve drives the rock bolt to rotate counterclockwise, the hypotenuse of the right trapezoidal groove is clamped with the hypotenuse of the right trapezoidal structure of the claw.
[0010] Further, in the initial state, the movable sleeve on the outer clamping sleeve is located on the right side of the straight groove on the inner ejector rod under the elastic force of the spring. When the end of the inner ejector rod contacts the end of the rock bolt, relative movement occurs between the inner ejector rod and the outer clamping sleeve under the continuous movement and extrusion of the propulsion mechanism.
[0011] The present invention application has the following technical effects:
[0012] The rock bolt and cable anchor drilling rig for geological disaster survey provided by the present application, for the setting of the pressure head member and its structure thereon, when the propulsion mechanism on the anchoring drilling rig adds a new rock bolt downward, the claw can be clamped into the right trapezoidal groove, and when it rotates in the corresponding direction, the right angle side or the oblique angle side between the claw and the right trapezoidal groove is clamped, thereby driving the rock bolt to rotate and transmitting radial power for drilling operations, or driving the rock bolt to rotate in the reverse direction and transmitting radial and axial power to pull it out, thereby effectively reducing the idling time of the propulsion mechanism thereon, avoiding the ineffective work of the anchoring drilling rig, reducing energy consumption while improving the drilling efficiency.

Detailed implementation manners
[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0023] As Figure 1 shown, an anchor cable drill for geological disaster survey includes an anchor rod 1 and an indenter member 2. A right-angled trapezoidal groove 5 is formed on the outer surface of the other end of the anchor rod 1; as Figure 3 , Figure 4 shown, the indenter member 2 includes an inner ejector rod 6 with one end being a conical structure. A plurality of groups of straight grooves 10 arranged in an annular array are formed on the outer surface of the inner ejector rod 6 along the direction of its central axis, and an annular groove 11 is formed in the middle of the outer surface of the inner ejector rod 6. An outer clamping sleeve 7 is movably sleeved on one side of the outer surface of the inner ejector rod 6, as Figure 5As shown in the figure, the outer collet 7 includes a movable sleeve 12 movably sleeved on the outer surface of the inner ejector rod 6. A claw 13 corresponding to the right trapezoidal groove 5 on the anchor rod 1 is installed on the outer surface of the movable sleeve 12. A limiting block 14 is provided on the inner wall of the movable sleeve 12, and the limiting block 14 is engaged with the straight groove 10 on the inner ejector rod 6. Thus, radial power can be transmitted between the inner ejector rod 6 and the outer collet 7 through the limiting block 14 and the straight groove 10, and relative movement can occur along the central axis direction of the inner ejector rod 6. The inner ejector rod 6 and the outer collet 7 are connected by a spring 8 movably sleeved on the annular groove 11. On the other side of the outer surface of the inner ejector rod 6, a connecting sleeve rod 9 fixedly connected to the propulsion mechanism on the anchoring drill is movably sleeved through the straight groove 10 thereon.
[0024] As Figure 2 shown in the figure, in this technical solution, an external thread 3 is provided on the outer surface of one end of the anchor rod 1, and an internal thread 4 matching the external thread 3 is provided on the inner wall of the other end of the anchor rod 1. Thus, a plurality of groups of anchor rods 1 can be fixedly connected end to end by threads.
[0025] As Figure 6 shown in the figure, in this technical solution, the end of the claw 13 is provided with a right trapezoidal structure corresponding to the right trapezoidal groove 5, and the length of the wide side of the trapezoidal structure of the claw 13 is less than the length of the narrow side of the right trapezoidal groove 5. Thus, it is ensured that the claw 13 can be stably inserted into the right trapezoidal groove 5 on the anchor rod 1, and when the outer collet 7 makes a clockwise rotation and extrusion action, the anchor rod 1 can be synchronously driven to make a clockwise rotation and extrusion action for drilling operations.
[0026] As Figure 6 shown in the figure, in this technical solution, when the outer collet 7 drives the anchor rod 1 to make a counterclockwise rotation action, the hypotenuse of the right trapezoidal groove 5 is engaged with the hypotenuse of the right trapezoidal structure of the claw 13. Thus, when pulling out the pipe counterclockwise, a tensile force along its central axis direction can be applied to the anchor rod 1, so that the phenomenon of automatic detachment between the anchor rod 1 and the pressure head member 2 does not occur.
[0027] In this technical solution, in the initial state, the movable sleeve 12 on the outer collet 7 is located on the right side of the straight groove 10 on the inner ejector rod 6 under the elastic force of the spring 8. When the end of the inner ejector rod 6 contacts the end of the anchor rod 1, under the continuous movement and extrusion of the propulsion mechanism, relative movement occurs between the inner ejector rod 6 and the outer collet 7, and the claw 13 is pushed into the right trapezoidal groove 5 on the anchor rod 1. Thus, when rotation occurs, they can be engaged with each other.
