Description

Technical Field

[0001] The invention relates to the technical field of shaft construction, and in particular to a shaft construction umbrella drill drilling angle control mechanism. Background Art

[0002] As the main auxiliary structure in the construction of extra-long tunnels, vertical shafts play a key role in improving the ventilation efficiency of tunnel construction and operation. When drilling wells in rocky strata in mountainous areas, the drilling and blasting method is widely used in vertical shaft excavation construction because of its flexible construction and fast rock breaking and well completion progress. At present, large-diameter vertical shafts use umbrella drilling machinery. However, during the drilling operation, it is difficult for construction workers to control the angles of the inclined slot holes and peripheral holes, resulting in poor slotting and throwing effects. In addition, since the umbrella drill will tilt and rotate during drilling, it is difficult for operators to clearly know the degree of inclination of the borehole, and the length and depth of the borehole are also difficult to obtain in actual operation.

[0003] In view of the above, we provide a vertical shaft construction umbrella drill drilling angle control mechanism to solve the above problems. Summary of the invention

[0004] In view of the above situation, the present invention provides a vertical shaft construction umbrella drill drilling angle control mechanism, which moves with the drill rod through a driving bar until the drill rod is drilled into the well body stone and slides relative to the driving bar to obtain the drilling length of the drill rod.

[0005] A vertical shaft construction umbrella drill drilling angle control mechanism comprises a frame and a drill rod, the drill rod is rotatably arranged on one side of the frame, a driving mechanism is arranged in the middle of the drill rod, the driving mechanism comprises a driving ring and a driving strip, the driving ring is rotatably arranged in the middle of the drill rod, the driving strip is slidably arranged on the surface of the driving ring, an extrusion tube is integrally arranged at the bottom of the driving ring, a side rod is slidably arranged on the inner wall of the extrusion tube, the side rod is integrally arranged on one side of the driving strip, a depth measuring mechanism is arranged on one side of the frame, the depth measuring mechanism comprises a positioning block, a rotating block, a translation plate and a side frame, the positioning block is slidably arranged on one side of the frame, the rotating block is rotatably arranged on one side of the positioning block, the translation plate is slidably arranged on one side of the rotating block, and the side frame is rotatably arranged on one side of the frame.

[0006] The above technical solution has the following beneficial effects: In this solution, the driving bar moves together with the drill rod until the drill rod is opened and drilled into the stone of the well body and generates relative sliding with the driving bar. The relative sliding is measured and compared to the positioning block, so that the positioning block is moved. The movement of the positioning block can drive the translation plate to move, so that the movement distance of the positioning block and the movement distance of the translation plate correspond to the trigonometric function relationship, and the pressure bucket is controlled to record the initial pressure and the final pressure, and the data such as the drilling depth and length of the drill rod are obtained. The outlet of the rotary nozzle can also be adjusted according to the change of the frame angle, so that the liquid sprayed by the rotary nozzle is more powerful, thereby cooling the surface of the drill rod.

DETAILED DESCRIPTION

[0009] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 9It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0010] This embodiment provides a vertical shaft construction umbrella drill drilling angle control mechanism, as shown in the attached Figure 1-9 As shown in the instruction manual, Figure 1 The overall structure diagram of this scheme is taken from one side of the actual umbrella drill. The frame 1 is on the side of the umbrella drill. The frame 1 needs to be stably supported on the side of the umbrella drill by a hydraulic push rod and other structures. Figure 2 This is a single-side cutting diagram of the frame 1 of this solution. Because there is a drill rod 2 in the middle of the frame 1, the drill rod 2 is circular, and the cutting surface is cut through the center of the drill rod 2. Figure 4 Taken from the instruction manual Figure 2 A dividing line is provided at the bottom of the frame 1, and the instruction manual is below the dividing line. Figure 4 , Instructions attached Figure 5 The sectional view is cut with the center of the side bar 5. Figure 8 One side of the vertical strip 20 is cut as the cutting surface, and the instructions are attached. Fig. 9The frame 1 is hidden, and other structures are suspended. A rotatable drill rod 2 is arranged in the middle of the frame 1. The rotation of the drill rod 2 depends on the motor to drive the rotation. Since the rotary drilling of the drill rod 2 belongs to the prior art, the motor and other components are not shown in this scheme. The drill rod 2 can not only rotate, but also move downward, that is, on the basis of the rotation driven by the motor, a hydraulic push rod is added to enable it to drill towards a deeper position. This is the normal operating principle of the umbrella drill. In layman's terms, a lifting mechanism is added while the drill rod 2 rotates. This scheme is improved on the basis of the hydraulic movement drilling of the umbrella drill, so how the drill rod 2 is rotated and lifted is not introduced in detail (the specific structure refers to the structure of the drill bit 27, and the drill bit 27 can also be rotated and extended). A driving ring 3 is rotatably arranged in the middle of the drill rod 2. The driving ring 3 and the drill rod 2 can rotate but cannot be separated. A driving bar 4 is slidably arranged on one side of the driving ring 3. There is a long spring between the driving bar 4 and the driving ring 3, so that the distance between the bottom of the driving bar 4 and the bottom of the drill rod 2 is small, but it does not affect When the drill rod 2 rotates, the middle part of the driving strip 4 is hollow, and the hollow shape is a cylinder. In order to fix the directions of the driving strip 4 and the driving ring 3, a cylinder adapted to the upper part of the driving strip 4 is integrally arranged on the top of the frame body 1. This ensures that the driving strip 4 will not change its left and right position but only change its up and down position (the same is true for the driving ring 3). In this way, the extension of the drill rod 2 will cause the driving ring 3 and the driving strip 4 to move together. In this case, there will be no relative sliding between the driving ring 3 and the driving strip 4. Once the drill rod 2 is rotated into the well (drilling When the drill rod 2 enters the bottom of the well), it will slide relative to the driving strip 4, and the drill rod 2 and the driving ring 3 can move together, so the driving strip 4 and the driving ring 3 can slide relative to each other. In this way, the depth of the drill rod 2 penetrating into the well body is equivalent to the relative sliding between the driving strip 4 and the driving ring 3 (here it is not absolutely equivalent, there is a certain error). Since a side rod 5 is integrally provided on one side of the driving strip 4 and the side rod 5 and the extrusion tube are sealed and slidable, the gas inside can be squeezed out between the side rod 5 and the extrusion rod, as shown in the attached manual Figure 7 As shown, the shape of the extrusion tube is a cylinder, and the side rod 5 is a piston. The bottom of the side rod 5 contacts the bottom of the extrusion tube. A through hole is provided above the bottom of the side rod 5, so that the extruded gas can enter the middle of the side rod 5. The top of the side rod 5 is connected to a connecting pipe 13, which is a hose. The other end of the connecting pipe 13 is connected to a metering tank 14. The metering tank 14 is provided inside one side of the frame 1, as shown in the attached manual. Figure 3 and 6As shown, the difference between the two figures is the three-dimensional view and the front view. A positioning block 6 is slidably arranged on the surface of the metering groove 14. Below the positioning block 6 is a rectangular block, and the upper part extends to the inside of the metering groove 14 and slides with the metering groove 14 in a sealed manner. Since the drill rod 2 and the driving bar 4 can slide relative to each other and are converted into gas squeezed out by the side rod 5, the present scheme measures the vertical depth of the drill rod 2 by the amount of squeezed gas (the vertical depth here is the vertical distance from the bottom of the drill bit 27 to the horizontal), and the squeezed gas reaches the metering groove 14. Since the positioning block 6 does not move, because the positioning block 6 is below the control push rod 15, the control push rod 15 is an electric push rod, and the control push rod 15 is an electric push rod. The control of the rod 15 is controlled by the upper spring 17 and the lower spring 18. A rod extends above the positioning block 6. The middle part of the rod is a soft film 16. A blocking mechanism is formed between the soft film 16 and the positioning rod, so that the gas entering the connecting pipe 13 cannot move downward, and the soft film 16 is depressed downward due to the compression of the gas, so that the upper spring 17 is squeezed (the upper spring 17 and the lower spring 18 are respectively at the upper and lower ends of the soft film 16, and the upper spring 17 and the lower spring 18 are both equipped with pressure sensors. The judgment principle of the pressure sensor here is that pressure can be generated, because one end of the upper spring 17 and the lower spring 18 are both suspended, as shown in the attached manual Figure 6As shown, a baffle is provided between the upper spring 17 and the lower spring 18, and the baffle is integrally provided on the positioning block 6, and the upper end of the upper spring 17 is connected to the soft film 16, and the lower end is not connected to the baffle, so that the soft film 16 is depressed downward and squeezes the upper spring 17. At this time, the upper spring 17 is triggered by pressure, so that the control push rod 15 drives the positioning block 6 to translate downward, so as to increase the air capacity above the metering groove 14, until the upper spring 17 stops moving without receiving pressure, and the lower spring 18 is also under pressure, so that the control push rod 15 translates upward until both the upper spring 17 and the lower spring 18 are under pressure). The upper spring 17 moves the control push rod 15 downward, so that The gas capacity squeezed by the connecting pipe 13 is converted into the distance of the positioning block 6 moving downward, so that the drilling length of the drill rod 2 is converted into the moving distance of the positioning block 6. The moving distance of the positioning block 6 represents the drilling length of the drill rod 2. Since the angle of the frame 1 is not vertical, the drilling length and the drilling depth are inconsistent. The drilling length and the drilling depth are equivalent to the hypotenuse and the right angle side of the right triangle. If you want to know the right angle side (drilling depth) here, you need to know the proportional relationship. Since the angle of the frame 1 changes at any time, a certain reference side is required. In this solution, a side frame 9 is rotatably provided on one side of the frame 1. The side frame 9 is equivalent to the vertical side. When the side frame 9 is not started, it coincides with the angle of the frame 1. (The plug-in block 31 can be used to clamp the plug-in slot 32. The plug-in block 31 is controlled by the plug-in frame 30. The movement of the plug-in frame 30 will be introduced below). When the angle of the frame 1 is fixed, the plug-in block 31 is disengaged from the plug-in slot 32, so that the side frame 9 is automatically upright under the action of gravity (the center of gravity of the side frame 9 is at the bottom, and the center of gravity is just in the middle of the side frame 9, which ensures that the side frame 9 is vertical). In this way, the side frame 9 acts as the right angle side of the right triangle. At this time, since the side frame 9 rotates, the position of the positioning block 6 does not move, so that the translation plate 8 moves upward (at the same time, the rotating block 7 slides and rotates on the translation plate 8 to adapt, which ensures that the positioning block 6 The translation plate 8 is still on a horizontally vertical line, so that when the positioning block 6 moves, the positioning work is completed. The rotation center of the side frame 9, the positioning block 6 and the translation plate 8 form a right triangle. When the angle of the right triangle remains unchanged, the hypotenuse increases and the right-angled side increases proportionally. In this way, the drilling depth of the drill rod 2 is obtained, because the drilling length represents the moving distance of the positioning block 6). The sliding distance of the translation plate 8 is compared with the sliding of the positioning block 6. In this way, it is only necessary to locate the initial position and the final position of the translation plate 8 to obtain the drilling depth. A pressure rod 10 is integrally provided on one side of the translation plate 8, and one side of the pressure rod 10 is overlapped on the pressure bucket 11 (as shown in the attached manual). Figure 3As shown in the figure, since the side frame 9 rotates vertically, the position of the translation plate 8 is changed, which causes the translation plate 8 to move upward to squeeze the pressure bucket 11. This is the recorded initial position of the pressure bucket 11. As the translation plate 8 moves downward, the pressure rod 10 moves downward. There are two situations. The first is that the pressure rod 10 moves downward but has not yet reached the center position of the pressure bucket 11 (the center position of the pressure bucket 11 is shown in the attached manual). Figure 3 As shown, at this time, the position of the pressure rod 10 is the center position of the pressure bucket 11), so the pressure spring 12 only needs to record how much the pressure is reduced to compare the drilling depth. The second is that the pressure rod 10 moves downward and crosses the center position of the pressure bucket 11 (the pressure spring 12 will become zero). At this time, it is necessary to record the initial pressure and the final pressure of the pressure spring 12. The final pressure can be obtained by adding the two. A pressure sensor needs to be installed on the pressure spring 12, so that the drilling depth of the drill rod 2 can be recorded and compared (this solution is obtained by comparison, and the first step is to compare the moving distance of the positioning block 6 by squeezing the gas). The penetration length of the drill rod 2 is easily obtained through step-by-step experiments (that is, a determined ratio). In the second step, the moving distance of the translation plate 8 is obtained through trigonometric comparison. This ratio actually changes with the angle change of the frame 1 and the side frame 9 (the trigonometric ratio is uncertain, so comparison is required). Finally, the penetration depth is obtained by comparing the pressure spring 12, which is convenient for obtaining the drilling depth (vertical) and the rotation length (oblique) of the drill rod 2 under different angles. This is the core mechanism of this solution. The pressure spring 12 needs to be electrically connected to the platform of the umbrella drill so that the operator can obtain the data on the pressure spring 12. Finally, two other structures of this scheme are introduced. The first is a rotating nozzle 21. The rotating nozzle 21 is rotatably set on one side of the bottom of the frame 1. There is a water hose 25 above the rotating nozzle 21, and one end of the water hose 25 is extended to the water tank (this scheme does not improve how the water tank supplies water. It adopts the existing technology. A water pump needs to be designed in the water tank, and the water tank needs to be installed on the umbrella drilling platform so that the liquid in the water tank reaches the rotating nozzle 21. It should be noted that the water delivery of the water pump will never change). The liquid in the water tank is transported to the rotating nozzle 21 by the water pump. Since the angle between the frame 1 and the side frame 9 is constantly changing, and the larger the angle, the greater the power required for normal water spraying to overcome free fall, so this scheme designs an arc piece 19. The front view of the arc piece 19 is an arc, and the three-dimensional shape is concave in the middle and gradually convex toward both sides, and the arc piece 19 is slidably set on one side of the frame 1. Due to the lower side of the rotation center of the side frame 9 (as shown in the attached manual Fig. 9As shown), it is just attached to the middle part of the concave arc piece 19, so that no matter which direction the side frame 9 rotates (the rotation of the side frame 9 relies on gravity, and the mass of the side frame 9 is large), the arc piece 19 is squeezed back, so that the arc piece 19 moves toward one side, and the greater the rotation angle of the side frame 9, the greater the movement distance of the arc piece 19. One side of the arc piece 19 has a spring reset, and one end of the arc piece 19 is overlapped on the vertical bar 20. The vertical bar 20 is vertically slidably arranged on the inner side of the frame body 1, and there is an oblique notch above the vertical bar 20 (as shown in the attached manual Figure 7 and 8 The upper side is enlarged), this oblique groove is overlapped on one side of the arc piece 19, so that when the arc piece 19 moves toward the frame body 1, it will drive the vertical bar 20 to move upward, and the upward movement of the vertical bar 20 can make the rotary nozzle 21 rotate toward the drill rod 2, that is, the greater the rotation angle, the more the rotary nozzle 21 fits toward the drill rod 2, and can also control the rotation of the outlet bar 22 to make the outlet of the rotary nozzle 21 smaller, because the outlet bar 22 is rotatably arranged (softly rotated through a notch on one side of the outlet bar 22, and the sealing is ensured during the soft rotation) on one side of the rotary nozzle 21, and an extrusion block 23 is slidably arranged on one side of the rotary nozzle 21, and a spring is arranged between the extrusion block 23 and the rotary nozzle 21 for reset, and an extrusion frame 24 is integrally arranged on one side of the frame body 1, so that the vertical bar 20 moves to control the rotation of the rotary nozzle 21, and the extrusion block 23 is attached to the extrusion frame 24 for extrusion, so that The squeezing block 23 moves toward the outlet strip 22, so that the outlet strip 22 has to rotate, that is, the outlet of the rotating nozzle 21 is smaller. Due to the limited amount of water delivered by the water pump, the force of the rotating nozzle 21 spraying is indirectly increased to overcome the gravity of the oblique spraying, so that the rotating nozzle 21 can spray more closely to the surface of the drill pipe 2, and cool the surface of the drill pipe 2. Finally, the positioning push rod 26 of this scheme is introduced. The positioning push rod 26 is used to fix the angle of the side frame 9. The positioning push rod 26 is a kind of electric push rod. The protruding end of the positioning push rod 26 has a piece, and a drill bit 27 is rotatably arranged on this piece. A motor is installed above the drill bit 27, so that the drill bit 27 can extend downward while rotating and turn into the well body, thus ensuring the stability of the side frame 9. A long strip 28 is overlapped on one side of this piece, and a spring is arranged between the long strip 28 for buffering, which makes the long strip 28 also drive downward movement at the same time. The long strip 28 moves downward (as shown in the attached manual Figure 1The plug-in frame 30 is moved upward by the long strip 28 moving downward, and the surface of the reverse strip 29 is designed with an adaptive notch to increase the fault tolerance. The plug-in frame 30 moves upward, and the plug-in block 31 is slidably provided in the middle and plugged into the plug-in slot 32 to fix the frame body 1. A spring is provided between the plug-in frame 30 and the plug-in block 31 to support the plug-in block 31, so that even if the plug-in block 31 is not inserted into the plug-in slot 32, it only needs to be slightly rotated to insert the plug-in block 31 into the plug-in slot 32, and this process is earlier than the drill bit 27 is fixed, so that the angle of the side frame 9 on the drill rod 2 is fixed first, and then the drill bit 27 is fixed. Because the strip 28 and the bottom sheet of the positioning push rod 26 have a sliding space and a spring, the plug-in block 31 is inserted into the plug-in slot 32 before the drill bit 27 is inserted. The plug-in slot 32 is arranged on one side of the frame 1 and at the rotation center of the side frame 9. The plug-in slot 32 is a plurality of annular arrays. A drill rod 2 is rotatably arranged on one side of the frame 1. A driving mechanism is arranged in the middle of the drill rod 2.

The inner wall of the extrusion tube 33 is slidably provided with a side rod 5. The side rod 5 is integrally arranged on one side of the driving strip 4.

The other end of the connecting pipe 13 is connected to a metering groove 14. The surface of the metering groove 14 is slidably arranged with the positioning block 6. The metering groove 14 is opened on one side of the frame 1.
