Description

Technical Field

[0001] This invention relates to the field of coal mine tunneling support technology, specifically to a bolt drilling rig frame. Background Technology

[0002] Anchor bolt drilling rigs are drilling tools used in anchor bolt support work in coal mine roadways. They offer significant advantages in improving support effectiveness, reducing support costs, accelerating roadway construction, reducing auxiliary transportation volume, alleviating labor intensity, and increasing roadway cross-sectional utilization. Currently, the commonly known structure of anchor bolt drilling rigs for coal mines is a guide rod type: including a base frame, slide, power head, guide sleeve, clamp, and propulsion cylinder. Specific structure details are shown in the attached instruction manual. Figure 5 As shown, the disadvantages of this structure are:

[0003] 1. The height dimension is large, the structure is not compact, and the overall weight is relatively heavy. Because the base frame is a double-layer structure and the guide sleeve is also a separate independent guide sleeve, it requires a large structural space in the height direction, resulting in a large overall weight.

[0004] 2. The guide rods are all individually guided, resulting in low structural strength and guiding efficiency. The structure relies solely on these independent guide rods for strength, leading to poor strength retention during full extension and movement. For example, the carriage is only connected to the overall structure and maintained by two guide rods at its lower end; the remaining guide rods do not contribute to the carriage's guidance or reinforcement. Similarly, the gripper is only connected to the overall structure and maintained by the guide rod at its lower end; the remaining guide rods do not contribute to the gripper's guidance or reinforcement. The hydraulic cylinder is used only as a propulsion cylinder and not as a guiding or reinforcing structure. This design results in significant redundancy, poor overall strength, large space occupation, and heavy overall weight. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anchor drilling rig frame that solves the problems of insufficient structural compactness, low structural strength, and low guiding efficiency of current anchor drilling rig frames.

[0006] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution:

[0007] This invention provides a bolt drilling rig frame, comprising: a base frame, guide sleeves on both sides of the top of the base frame, a first through hole and a second through hole on the guide sleeve, a first guide rod slidably sleeved on the guide sleeve through the first through hole, a second guide rod slidably sleeved on the guide sleeve through the second through hole, the ends of the two first guide rods away from the base frame being connected to the same slide, the slide having a first guide hole matching the second guide rod, and the ends of the two second guide rods away from the base frame passing through the first guide hole and connected to the same clamp;

[0008] The top of the guide sleeve is connected to the cylinder of the drive cylinder. The slide is provided with a second guide hole that matches the cylinder rod of the drive cylinder. The cylinder rod of one drive cylinder is connected to the slide, and the cylinder rod of the other drive cylinder passes through the second guide hole and is connected to the clamp.

[0009] The slide has multiple third guide rods on its side wall near the guide sleeve, and the multiple third guide rods are slidably connected to the same power head; the axes of the first guide rod, the second guide rod, the third guide rod and the drive cylinder are parallel to each other.

[0010] Furthermore, the guide sleeve is located at one end of the base frame, and the cylinder of the drive cylinder is connected to the other end of the base frame.

[0011] Furthermore, a support plate is provided at the end of the base frame away from the guide sleeve, and the side wall of the support plate is fixedly connected to the tail end of the drive cylinder barrel.

[0012] Furthermore, multiple reinforcing ribs are provided between the support plate and the base frame.

[0013] Furthermore, the end of the first guide rod closest to the base frame is connected to the same horizontal plate after passing through the guide sleeve, and the end of the third guide rod furthest from the carriage is connected to the horizontal plate.

[0014] Furthermore, the guide sleeve and the drive cylinder are arranged symmetrically about the central axis of the base frame.

[0015] Furthermore, the first guide rod is located below the second guide rod.

[0016] Furthermore, there are two third guide rods arranged between the guide sleeves.

[0017] Furthermore, a support seat is movably sleeved on the third guide rod, and the top of the support seat is connected to the bottom of the power head to realize the sliding connection between the third guide rod and the power head.

[0018] Furthermore, the base frame is provided with ear plates on both sides, and the ear plates are provided with multiple mounting holes.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. The first guide rod, the second guide rod, the drive cylinder, the guide sleeve and the slide cooperate with each other in this invention, so that the main guide components have a composite guide reinforcement function, which improves the guiding and supporting function of the frame, and has better bending and torsional resistance, smaller overall size, more compact structure and lighter weight;

[0021] 2. The cooperation between the drive cylinder, the base frame and the guide sleeve in this invention ensures that both ends of the cylinder barrel of the drive cylinder are stably supported, thereby improving the structural strength, shortening the overall length of the device, improving the structural compactness, and facilitating installation and layout.

[0022] 3. The base frame in this invention adopts a single-layer structure design, which reduces the overall spatial dimensions of the structure and makes it easier to arrange when the space requirements of coal mine machinery are relatively strict.

[0023] 4. By arranging the second guide rod on the upper part of the guide sleeve, the present invention can reduce the bending moment arm during operation, thereby significantly improving the bending resistance performance. It can also greatly reduce the height of the clamp, compress the structural size, and reduce the overall weight of the device. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the purpose of simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figures 1-4 As shown, this embodiment of the invention provides an anchor drilling rig frame, including: a base frame 1, guide sleeves 2 on both sides of the top of the base frame 1, a first through hole 21 and a second through hole 22 on the guide sleeves 2, a first guide rod 3 slidably sleeved on the guide sleeves 2 through the first through hole 21, and a second guide rod 4 slidably sleeved on the guide sleeves 2 through the second through hole 22, the ends of the two first guide rods 3 away from the base frame 1 being connected to the same slide 5, the slide 5 having a first guide hole 51 matching the second guide rod 4, and the ends of the two second guide rods 4 away from the base frame 1 passing through the first guide hole 51. The guide sleeve 2 is connected to the same clamp 6 after the guide hole 51; the top of the guide sleeve 2 is connected to the cylinder of the drive cylinder 7; the slide 5 is provided with a second guide hole 52 that matches the cylinder rod of the drive cylinder 7; the cylinder rod of one drive cylinder 7 is connected to the slide 5; the cylinder rod of another drive cylinder 7 passes through the second guide hole 52 and is connected to the clamp 6; multiple third guide rods 8 are provided on the side wall of the slide 5 near the guide sleeve 2; the multiple third guide rods 8 are slidably connected to the same power head 9; the axes of the first guide rod 3, the second guide rod 4, the third guide rod 8 and the drive cylinder 7 are parallel to each other.

[0035] Specifically, for the clamp 6, the two second guide rods 4 can slide along the second through holes 22 on the guide sleeve 2, thereby limiting and guiding the clamp 6. The cylinder rod of a drive cylinder 7 extends through the second guide hole 52 and drives the clamp 6 to move. This cylinder rod can also be used as a guide rod, thus effectively providing three guide rods to guide and fix the clamp 6, improving the overall structural strength and guiding efficiency. As the slide 5 extends, the distance between the slide 5 and the clamp 6 gets closer. Since the slide 5 is movably mounted on the second guide rods 4 through the first guide hole 51, the force borne by the second guide rods 4 is transmitted to the slide 5, significantly improving the strength and rigidity of the second guide rods 4.

[0036] Specifically, for the slide 5, the two first guide rods 3 can slide along the first through hole 21 on the guide sleeve 2, thereby limiting and guiding the slide 5. The cylinder rod of the other drive cylinder 7 extends to drive the slide 5 to move. Therefore, when the slide 5 extends, it is equivalent to having three guide rods for guidance and fixation. In addition, there are cylinder rods of the drive cylinder 7 used to drive the clamp 6 and two second guide rods 4 for reinforcement and guidance. Therefore, the strength and rigidity of the slide 5 are greatly enhanced, and its stability is high.

[0037] Specifically, for the power head 9, the center of the power head 9 should be arranged concentrically with the clamping center of the clamp 6. The power head 9 can be stably supported by the limiting guidance of multiple third guide rods 8.

[0038] Specifically, for the base frame 1, the base frame 1 is designed with a single-layer structure, which reduces the overall spatial size of the structure and makes it easier to arrange when the space requirements of coal mine machinery are relatively strict.

[0039] In this embodiment, the guide sleeve 2 is located at one end of the base frame 1, and the cylinder of the drive cylinder 7 is connected to the other end of the base frame 1.

[0040] Specifically, the above-mentioned configuration provides stable support at both ends of the cylinder barrel of the drive cylinder 7, thereby improving structural strength, shortening the overall length of the device, improving structural compactness, and facilitating installation and layout.

[0041] The above-mentioned design ensures that the main components have a composite guiding and reinforcing effect, thereby improving the guiding and supporting function of the frame, resulting in better bending and torsional resistance, smaller overall size, and lighter weight.

[0042] In this embodiment, a support plate 10 is provided at the end of the base frame 1 away from the guide sleeve 2, and the side wall of the support plate 10 is fixedly connected to the tail end of the cylinder of the drive cylinder 7.

[0043] Specifically, the support plate 10 is perpendicular to the base frame 1, thereby supporting the drive cylinder 7 and improving the stability of the drive cylinder 7.

[0044] In this embodiment, a plurality of reinforcing ribs 11 are provided between the support plate 10 and the base frame 1.

[0045] Specifically, the reinforcing ribs 11 are preferably two and symmetrically arranged on both sides of the support plate 10, which can reduce the stress concentration at the connection between the support plate 10 and the base frame 1, improve the support strength of the support plate 10, and ensure the stability of the structure.

[0046] In this embodiment, the ends of the two first guide rods 3 near the base frame 1 are connected to the same horizontal plate 12 after passing through the guide sleeve 2, and the end of the third guide rod 8 away from the slide 5 is connected to the horizontal plate 12.

[0047] It should be noted that the ends of the third guide rod 8 and the first guide rod 3 are connected to each other through the cross plate 12, so that both ends of the third guide rod 8 are supported, thereby reducing the stress concentration at local positions of the third guide rod 8, improving the load-bearing capacity of the third guide rod 8, and enabling the power head 9 to obtain more stable guidance and support.

[0048] Understandably, due to the above-mentioned configuration, the carriage 5 can also be supported by multiple third guide rods 8 during the extension process, thereby further improving the load-bearing capacity of the carriage 5 and making the movement of the carriage 5 more stable.

[0049] In this embodiment, the guide sleeve 2 and the drive cylinder 7 are arranged symmetrically about the central axis of the base frame 1.

[0050] Specifically, the symmetrical arrangement of the guide sleeve 2 and the drive cylinder 7 enables the left and right ends of the slide 5 and the clamp 6 to be subjected to balanced forces, thereby avoiding stress concentration and improving the overall stability and support strength of the device.

[0051] In this embodiment, the first guide rod 3 is located below the second guide rod 4.

[0052] It should be noted that by arranging the second guide rod 4 on the upper part of the guide sleeve 2, the bending moment arm borne during operation can be reduced, thereby significantly improving the bending resistance. Furthermore, since the clamping center above the clamp 6 needs to be concentrically aligned with the center of the power head 9, the height of the clamp 6 is affected by the arrangement height of the second guide rod 4. Therefore, through the above arrangement, the height of the clamp 6 can be significantly reduced, thereby compressing the structural dimensions of the clamp 6 and reducing the overall weight of the device.

[0053] In this embodiment, there are two third guide rods 8, which are arranged between the guide sleeves 2.

[0054] It should be noted that the two third guide rods 8 can provide guidance and support to both sides of the power head 9, ensuring the stability of the power head 9. However, this is not the only possibility; there can be three or more third guide rods 8, which is not limited here.

[0055] Specifically, placing the third guide rod 8 between the guide sleeves 2 can improve the structural compactness of the device, reduce the overall spatial dimensions of the structure, and facilitate installation.

[0056] Preferably, the horizontal plate 12 has a convex structure to avoid motion interference with the second guide rod 4.

[0057] In this embodiment, a support seat 13 is movably sleeved on the third guide rod 8, and the top of the support seat 13 is connected to the bottom of the power head 9 to realize the sliding connection between the third guide rod 8 and the power head 9.

[0058] Specifically, the support base 13 has a "convex" structure, and its wider sidewall is fixedly connected to the power head 9 by bolts, so that the power head 9 can slide smoothly and stably along the third guide rod 8.

[0059] In this embodiment, the base frame 1 has ear plates 14 on both sides, and the ear plates 14 have multiple mounting holes 141.

[0060] During installation, the ear plate 14 can be fixed to the position to be arranged by using the mounting holes 141 with locking bolts, thereby completing the installation of the entire device. It has good stability, is easy to disassemble and assemble, and is convenient for practical use.

[0061] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
