Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor rod drilling machine support, especially to an anchor rod drilling machine support. BACKGROUND

[0002] The anchor rod drilling machine is a professional mechanical equipment for drilling and installing anchor rods, and is widely used in the fields of mine exploitation, tunnel construction, geotechnical engineering and the like. The drilling machine is commonly driven by power provided by a hydraulic system in underground. The drilling machine has the advantages of powerful power, high drilling precision, flexible operation and the like, and can adapt to rocks of different hardness and complex geological conditions, but the equipment is relatively heavy, a special hydraulic pump station needs to be equipped, and the maintenance requirement of the hydraulic system is relatively high. The hydraulic anchor rod drilling machine is provided with high-pressure oil by the hydraulic pump station, drives the hydraulic motor to rotate, and then drives the drill rod of the anchor rod drilling machine to perform drilling and the like.

[0003] The anchor rod drilling machine is commonly used with a support in use, such as the anchor rod drilling machine support of polar coordinate positioning disclosed in the patent with the announcement number CN220434779U, which comprises a horizontal telescopic structure, a vertically arranged rotating shaft, a drilling machine rotating sliding mechanism, an anchor rod drilling machine and a drill rod. One end of the horizontal telescopic structure is rotationally connected to the rotating shaft, and the other end is connected to the drilling machine rotating sliding mechanism. The anchor rod drilling machine is connected to the drilling machine rotating sliding mechanism, and the drill rod is connected to the output end of the anchor rod drilling machine. The anchor rod drilling machine can slide up and down on the drilling machine rotating sliding mechanism and rotate in the longitudinal plane.

[0004] The above existing scheme has obvious deficiencies. Since the anchor rod drilling machine generates a large backward reaction force when performing drilling operation, the anchor rod drilling machine in the scheme is only fixed on the lifting platform, and lacks a rear support structure, which leads to the phenomenon that the equipment is prone to overturning in actual use, seriously affecting the operation safety and stability. At the same time, the structure of the scheme is relatively complex, and the cost is high, which to a great extent limits its wide promotion and application in actual engineering. UTILITY MODEL CONTENT

[0005] In view of the problem that the backward reaction force of the anchor rod drilling machine is large when drilling, the scheme lacks a rear support, is prone to overturning in use, and has high cost, which is not conducive to popularization and use, the utility model provides an anchor rod drilling machine support.

[0006] To solve the above problems, the utility model adopts the technical scheme that,

[0007] The utility model provides an anchor rod drilling machine support, including the base, the middle part of base is fixedly arranged with first telescopic link, the first telescopic link is hinged with the mounting rod on the side away from the base, the mounting rod is fixedly arranged with the clamp for fixing anchor rod drilling machine, the rear end of mounting rod is telescopically arranged with the support rod.

[0008] Preferably, the rear part of the mounting rod is provided with a first through hole in the radial direction; the support rod is provided with a plurality of second through holes in the radial direction; the second through holes and the first through hole are cooperatively provided with a first bolt; the rear end of the support rod is provided with an abutting plate. The support rod slides in the mounting rod, the abutting plate abuts against the opposite surface of the tunneling face, and the first bolt fixes the position of the support rod in the mounting rod. The length of the support rod can be adjusted according to the actual working environment and requirements. This makes the anchor rod drilling machine support adapt to different distances of the opposite surface of the tunneling face, providing more accurate and stable support. The abutting plate increases the contact area, which can more evenly distribute the force when the anchor rod drilling machine drills a hole, further enhancing the support effect, effectively preventing the anchor rod drilling machine from overturning, improving the safety of the operation, and ensuring the stability of the support rod abutting against the opposite surface of the tunneling face in the tunnel.

[0009] Preferably, the abutting plate is welded to the rear end of the support rod; the abutting plate is in the form of a square plate. The abutting plate is firmly connected to the support rod. The abutting plate is welded to the rear end of the support rod, which provides a more secure connection than other connection methods, ensuring that the abutting plate will not easily separate from the support rod when the anchor rod drilling machine is operating, thus ensuring the reliability of the support structure and providing stable support to prevent the drilling machine from overturning. The abutting plate is in the form of a square plate, which increases the contact area with the opposite surface of the tunneling face. According to the principle of pressure, under the same pressure, the greater the contact area, the smaller the pressure. This can more evenly distribute the pressure generated during the operation of the anchor rod drilling machine to the opposite surface of the tunneling face, avoiding excessive local pressure that can cause instability in the support, and further improving the stability and safety of the support.

[0010] Preferably, the abutment plate comprises a flat plate, a hinge seat is fixedly arranged in the middle of the flat plate, and the rear end of the support rod is hinged to the hinge seat. The abutment plate is hinged to the rear end of the support rod through the hinge seat, so that the abutment plate can rotate flexibly relative to the support rod. In actual operation, the abutment plate can be self-adaptively adjusted according to the specific shape and angle of the opposite surface of the tunneling face, so as to ensure that the abutment plate always maintains good adhesion with the opposite surface of the tunneling face, effectively improves the supporting effect, and enhances the stability of the anchor rod drilling machine operation. The hinge seat is arranged in the middle of the flat plate and connected with the support rod, when the anchor rod drilling machine operation generates a reaction force, the stress can be evenly dispersed to the flat plate through the hinge seat, avoiding stress concentration leading to structural damage, prolonging the service life of the abutment plate and the support rod, and reducing the equipment maintenance cost.

[0011] Preferably, a blind hole is arranged at the front end of the mounting rod, an auxiliary rod is inserted into the blind hole, and a connecting plate is fixedly arranged at the end of the auxiliary rod away from the mounting rod. The drill bit part of the anchor rod drilling machine can be connected with the connecting plate by bolts, thereby increasing the firmness of the connection between the anchor rod drilling machine and the mounting rod. The plug-in design of the blind hole and the auxiliary rod can provide support for the drill bit of the anchor rod drilling machine when the anchor rod drilling machine is working, and the mounting method is simple and convenient to operate, so that the connection between the auxiliary rod and the mounting rod can be quickly completed, thereby reducing the installation time. Furthermore, when the auxiliary rod or the connecting plate is damaged, it is easy to disassemble and replace, thereby reducing the maintenance cost and difficulty, improving the maintainability of the equipment, reducing the equipment downtime, and improving the work efficiency.

[0012] Preferably, a second telescopic rod is hinged to the rear part of the mounting rod, the end of the second telescopic rod away from the mounting rod is hinged to the base, and a bolt is arranged on the second telescopic rod to fix the length of the second telescopic rod. The second telescopic rod is hinged between the rear part of the mounting rod and the base to form a stable triangular support structure, which can effectively disperse the backward reaction force generated when the anchor rod drilling machine drills a hole, thereby avoiding the overturning of the drilling machine due to insufficient support at the rear part, greatly improving the safety and stability of the operation. By fixing the length of the second telescopic rod by the bolt, the user can flexibly adjust the angle and height of the mounting rod according to the height of the roadway, the flatness of the ground and the actual drilling operation requirements, so that the support can adapt to different operating environments, thereby expanding the application range of the anchor rod drilling machine.

[0013] Preferably, a plurality of hinged plates are arranged on the base; the hinged plates hinge the second telescopic rod. The hinged plates are arranged on the base to hinge the second telescopic rod, so that the second telescopic rod can freely rotate in multiple directions. In different operation scenarios, the angle between the second telescopic rod and the base can be adjusted according to actual needs, thereby changing the support angle of the mounting rod, ensuring that the anchor rod drilling machine can obtain stable support in complex terrain and working conditions, and effectively improving the operation stability. The hinged structure allows the second telescopic rod to swing within a certain range, and when the anchor rod drilling machine is operating, the anchor rod drilling machine can buffer the external force through the swing of the second telescopic rod, thereby reducing the damage to the base and the entire support structure, and enhancing the adaptability of the support to different operation environments, thereby prolonging the service life of the equipment.

[0014] Preferably, the first telescopic rod comprises a first sleeve; the first sleeve is fixedly arranged on the base; a first circular rod is slidably arranged in the first sleeve; the first circular rod hinges the mounting rod; a reinforcing rod is arranged between the first sleeve and the base; a plurality of through holes are formed in the first sleeve and the first circular rod, and bolts can be arranged in the through holes to fix the length of the first telescopic rod. The first circular rod slides in the first sleeve, and the height of the mounting rod can be adjusted according to actual operation needs, such as different heights of the tunneling face or operation space. At the same time, the length of the first telescopic rod can be fixed by arranging bolts in the through holes of the first sleeve and the first circular rod, so as to control the height of the mounting rod, thereby greatly improving the adaptability of the anchor rod drilling machine support to diversified operation scenarios.

[0015] Preferably, the clamp comprises two groups; each group of clamps comprises two oppositely arranged arc-shaped plates; one end of the arc-shaped plates is fixedly arranged on the mounting rod; and the other ends of the two arc-shaped plates are connected by bolts. The rear part of the anchor rod drilling machine is placed between the two arc-shaped plates, and the bolts are fastened. Each group of clamps comprises two oppositely arranged arc-shaped plates, and the two arc-shaped plates are connected by bolts. This design can closely fit the anchor rod drilling machine and provide stable clamping force. When the drilling machine is operating, the drilling machine can be firmly fixed to prevent displacement or shaking, thereby ensuring drilling accuracy and operation safety. One end of the two arc-shaped plates is fixed on the mounting rod, and the other end is connected by bolts. The bolt spacing can be flexibly adjusted according to anchor rod drilling machines of different sizes and shapes, thereby realizing the adaptation to drilling machines of various specifications, improving the versatility of the support, and meeting different engineering needs.

[0016] It can be seen from the above technical solutions that the anchor rod drilling machine support has the following advantages: when the anchor rod drilling machine support is used, the base is placed on the ground of the tunnel, the rear part of the anchor rod drilling machine is fixed on the mounting rod by the clamp, the drill bit of the anchor rod drilling machine is arranged at the front end of the mounting rod to abut against the tunneling face, and the support rod arranged at the rear end of the mounting rod is arranged to abut against the opposite surface of the tunneling face, thereby providing support for the anchor rod drilling machine, preventing overturning, and reducing costs, which is conducive to popularization.

Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Example 1

[0026] like Figure 1 and Figure 2 As shown, an anchor bolt drilling rig support includes a base 1, a first telescopic rod 2 fixedly disposed in the middle of the base 1; an installation rod 3 is hinged to the end of the first telescopic rod 2 away from the base 1; a clamp 301 for fixing the anchor bolt drilling rig is fixedly disposed on the installation rod 3; and a support rod 4 is telescopically disposed at the rear end of the installation rod 3.

[0027] In use, the base 1 is stably placed at a predetermined position on the roadway ground, ensuring that the base 1 is in good contact with the ground without shaking or tilting. According to the height requirement of the working face, the length of the first telescopic rod 2 is adjusted. The anchor rod drill is moved to the installation rod 3 and fixed by the clamp 301 on the installation rod 3. The drill bit of the anchor rod drill is aligned with the tunneling face. At this time, according to the distance between the tunneling face and the rear end of the installation rod 3, the extension length of the support rod 4 is adjusted. The support rod 4 is stretched outward from the rear end of the installation rod 3 until the rear end of the support rod 4 is in contact with the opposite face of the tunneling face, and the position of the support rod 4 in the installation rod 3 is fixed at this time. The support rod 4 provided by the telescopic setting of the rear end of the installation rod 3 abuts against the opposite face of the tunneling face, providing support for the anchor rod drill to avoid overturning, and the cost is relatively low, which is conducive to popularization.

[0028] In the above arrangement, the first telescopic rod 2 comprises a first sleeve 201; the first sleeve 201 is fixedly arranged on the base 1; a first round rod 202 is slidably arranged in the first sleeve 201; the first round rod 202 is hingedly connected with the installation rod 3; a reinforcing rod 9 is arranged between the first sleeve 201 and the base 1; a plurality of through holes are formed in the first sleeve 201 and the first round rod 202, and bolts can be arranged in the through holes to fix the length of the first telescopic rod 2. The arrangement of the reinforcing rod 9 increases the firmness of the connection between the first telescopic rod 2 and the base 1. The rear part of the installation rod 3 is provided with a first through hole 302 in the radial direction; a plurality of second through holes 401 are arranged on the support rod 4 in the radial direction; the first bolt 5 is arranged in the second through hole 401 and the first through hole 302 in cooperation; the rear end of the support rod 4 is provided with an abutting plate 6. The support rod 4 slides in the installation rod 3, and the abutting plate 6 abuts against the opposite face of the tunneling face in the roadway, and the first bolt 5 fixes the position of the support rod 4 in the installation rod 3. The arrangement of the abutting plate 6 increases the contact area and ensures the stability of the support rod 4 abutting against the opposite face of the tunneling face in the roadway. The abutting plate 6 is welded at the rear end of the support rod 4; the abutting plate 6 is arranged in the form of a square plate, and the abutting plate 6 is firmly connected with the support rod 3. The clamp 301 is provided with two groups; each group of clamps 301 comprises two oppositely arranged arc-shaped plates; one end of the arc-shaped plate is fixedly arranged on the installation rod 3; the other end of the two arc-shaped plates is connected by a bolt. The rear part of the anchor rod drill is placed between the two arc-shaped plates, and fastened by the bolt. The U-shaped bracket 303 is welded at the rear end of the installation rod 3, which is convenient for operation and holding.

[0029] The mounting rod 3 is provided with a blind hole at the front end; the auxiliary rod 7 is inserted in the blind hole; and the connecting plate 701 is fixedly arranged at the end of the auxiliary rod 7 away from the mounting rod 3. The drill bit part of the anchor rod drilling machine can be connected with the connecting plate 701 through bolts, thereby increasing the firmness of the connection between the anchor rod drilling machine and the mounting rod 3. The second telescopic rod 8 is hingedly connected to the rear part of the mounting rod 3; the end of the second telescopic rod 8 away from the mounting rod 3 is hingedly connected to the base 1; and the second telescopic rod 8 is provided with bolts for fixing the length of the second telescopic rod 8. The mounting rod 3 can be further supported, the stability of the anchor rod drilling machine is ensured, and the accuracy of drilling is improved.

[0030] As shown in the drawings, the base 1 is provided with a plurality of hinged plates 101; and the hinged plates 101 are hingedly connected to the second telescopic rod 8. The hinged position of the second telescopic rod 8 to the base 1 can be adjusted according to the angle of drilling. Figure 3

[0031] In use, the anchor rod drilling machine support with the base 1 is carried to the predetermined position of the working site in the well. The base 1 provides basic support for the entire support, and the structure is stable, thereby facilitating the placement of the support on the roadway floor.

[0032] According to the height requirement of the working surface, the length of the first telescopic rod 2 is adjusted. The operator loosens the bolts inserted in the through holes of the first sleeve 201 and the first round rod 202, slides the first round rod 202 in the first sleeve 201, and then inserts the bolts again and tightens them after adjusting to the appropriate height, so as to fix the length of the first telescopic rod 2. The reinforcing rod 9 enhances the firmness of the connection between the first telescopic rod 2 and the base 1, and ensures the stability and reliability of the first telescopic rod 2 during adjustment and subsequent operation.

[0033] After the first telescopic rod 2 is adjusted to the position, the angle of the mounting rod 3 can be adjusted according to the requirement of the drilling direction. Since the first round rod 2 is hingedly connected to the mounting rod 3, the operator can manually rotate the mounting rod 3 to the required angle, and at this time, the first telescopic rod 2 provides support for the mounting rod 3.

[0034] The anchor rod drilling machine is fixed on the mounting rod 3 by means of the clamp 301. Each group of clamps 301 is composed of two oppositely arranged arc-shaped plates. The rear part of the anchor rod drilling machine is placed between the two arc-shaped plates, and the bolts at the other end of the arc-shaped plates are tightened, so that the clamp 301 firmly clamps the anchor rod drilling machine. At the same time, the drill bit part of the anchor rod drilling machine can be connected with the connecting plate 701 at the front end of the auxiliary rod 7 through bolts, thereby further increasing the firmness of the connection between the anchor rod drilling machine and the mounting rod 3, and the auxiliary rod 7 is inserted in the blind hole at the front end of the mounting rod 3.

[0035] ​The support rod 4 is adjusted in extension at the rear of the mounting rod 3. The operator first removes the first bolt 5 from the first through hole 302 and the second through hole 401, then slides the support rod 4 so that the abutting plate 6 at the rear end of the support rod 4 abuts against the opposite surface of the tunneling face in the tunnel. The abutting plate 6 is in the form of a square plate and is welded at the rear end of the support rod 4, thereby increasing the contact area with the opposite surface of the tunneling face and ensuring stable abutment. After determining that the position of the support rod 4 is appropriate, the first bolt 5 is inserted into the corresponding first through hole 302 and second through hole 401 and is tightened, thereby fixing the position of the support rod 4 in the mounting rod 3 and providing rear support for the mounting rod 3 and the anchor rod drilling machine to resist the backward reaction force generated during drilling.

[0036] According to the drilling angle, the hinge position of the second extension rod 8 and the base 1 is adjusted. The base 1 is provided with a plurality of hinge plates 101, and the second extension rod 8 is hinged to different hinge plates 101, so that the angle relationship between the second extension rod 8 and the base 1 can be changed. At the same time, the length of the second extension rod 8 is adjusted. The bolt on the second extension rod 8 is loosened, the second extension rod 8 is stretched or compressed to an appropriate length, and then the bolt is tightened for fixation. One end of the second extension rod 8 is hinged to the rear of the mounting rod 3, and the other end is hinged to the base 1, thereby further providing support for the mounting rod 3 and improving the stability of the anchor rod drilling machine during drilling, thereby ensuring the accuracy of drilling.

[0037] After the adjustment and installation of all the components are completed, the anchor rod drilling machine is started for drilling operation.

[0038] Embodiment 2

[0039] As shown in Figure 4 The difference between the embodiment 1 and the embodiment 2 is that the abutting plate 6 comprises a flat plate 601, and the hinge seat 602 is fixedly arranged in the middle of the flat plate 601, and the rear end of the support rod 4 is hinged to the hinge seat 602. The rest of the settings are the same as those of the embodiment 1. The abutting plate 6 can rotate on the support rod 3, which facilitates the flat plate 601 to abut against the opposite surface of the tunneling face in the tunnel and ensures the abutting area.

[0040] During actual operation, the abutting plate 6 can be self-adaptively adjusted according to the specific shape and angle of the opposite surface of the tunneling face, thereby ensuring that the abutting plate 6 always maintains good adhesion with the opposite surface of the tunneling face, effectively improving the support effect and enhancing the stability of the anchor rod drilling machine. The hinge seat 602 arranged in the middle of the flat plate 601 is connected with the support rod 4. When the anchor rod drilling machine generates a reaction force, the stress can be evenly dispersed to the flat plate 601 through the hinge seat 602, thereby avoiding stress concentration and causing structural damage, prolonging the service life of the abutting plate 6 and the support rod 4, and reducing the equipment maintenance cost.

[0041] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
