Description

Technical Field

[0001] This utility model belongs to the field of coal mine roadway drilling technology, and specifically relates to an anchor cable clamp device. Background Technology

[0002] In the process of tunnel excavation and anchoring support in mines, anchor bolts or cables are commonly used as support structures to reinforce the rock mass in order to improve the stability of the surrounding rock. Traditional mining equipment is mostly single-function drilling equipment, usually equipped with only a single drill rod propulsion mechanism, which cannot automatically clamp and control the anchor cable. Especially in anchor cable construction, because the anchor cable structure is relatively flexible and long, it cannot rely on tail drive to form an effective force transmission path like a rigid drill rod. It is necessary to use a clamping structure for multi-point positioning and clamping. However, existing clamping devices are generally simple in structure, have poor stability, uneven clamping force or insufficient guidance, which can easily lead to anchor cable deviation, slippage or damage, seriously affecting anchoring accuracy and work efficiency. At the same time, some clamping structures are bulky and not suitable for integration into small or medium-sized rock drilling rigs, limiting their widespread application in narrow tunnels. In view of this, it is necessary to provide an anchor cable clamping device with a compact structure, stable clamping, and precise guidance to meet the dual requirements of current mine tunnel construction for anchoring efficiency and equipment integration. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an anchor clamp device that can be used in narrow mine tunnels and can clamp the drill rod / anchor cable, so that a second drill rod / anchor cable can be pushed forward, thereby increasing the anchoring efficiency.

[0004] The technical solution adopted by this utility model is an anchor clamp device, including a front support rod, a connecting plate fixedly connected to the upper end of the front support rod, two clamp cylinders symmetrically arranged on the connecting plate, the two clamp cylinders being arranged opposite to each other, and a guide block connected to the output end of each clamp cylinder.

[0005] The present invention is further characterized in that,

[0006] The front support tool has two fixed slots and one first through slot, and the two fixed slots and the first through slot are arranged in an isosceles triangle.

[0007] The connecting plate has a second through slot at its center, which corresponds to and is the same size as the first through slot. The connecting plate also has four fixing holes symmetrically arranged on both sides.

[0008] The clamp cylinder has four fixing blocks evenly arranged around its circumference. The fixing blocks are connected to the fixing holes, and the output end of the clamp cylinder is connected to a piston rod.

[0009] The guide block has a hole at one end near the clamp cylinder, and the piston rod is inserted into the hole. The guide block has a V-groove at the other end away from the clamp cylinder.

[0010] The beneficial effects of this utility model are:

[0011] This utility model discloses an anchor cable clamping device. A connecting plate is installed on the top of the front support rod, and two clamping cylinders are symmetrically arranged on the connecting plate. The clamping cylinders drive guide blocks to simultaneously retract or open via piston rods, achieving precise clamping of the anchor cable. The guide blocks have V-grooves at their front ends, automatically adapting to anchor cables of different diameters and forming a self-centering structure, improving clamping stability and guiding accuracy. The symmetrical arrangement of the two clamping cylinders ensures a more uniform distribution of clamping force, significantly reducing anchor cable bending or slippage caused by eccentric loading. A second through-hole is formed in the center of the connecting plate, aligned with the through-hole of the front support rod, forming a continuous through-channel, facilitating through-operation of the anchor cable and improving positioning accuracy. The clamping cylinders are securely connected to the connecting plate via four circumferentially arranged fixing blocks, effectively improving the overall rigidity and durability of the device. This device has a compact structure, flexible installation, and is suitable for anchor cable construction in narrow tunnels or complex working conditions, significantly improving anchoring efficiency, clamping reliability, and equipment integration adaptability, showing promising prospects for widespread application.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0019] like Figure 1-5 As shown, this utility model discloses an anchor cable clamping device, including a front support rod 1. The front support rod 1 provides an installation foundation and guiding support for the clamping device during anchor cable construction. A connecting plate 2 is fixedly connected to the upper end of the front support rod 1. The connecting plate 2 is used to bear the installation load of the clamping cylinder 3 and maintain the overall structural stability. Two clamping cylinders 3 are symmetrically arranged on the left and right sides of the connecting plate 2. The two clamping cylinders 3 are arranged horizontally opposite each other and can be synchronously advanced towards the center during operation to ensure uniform force and coaxial clamping when clamping the anchor cable. The output end of each clamping cylinder 3 is connected to a guide block 4, which is made of high-strength wear-resistant alloy. The overall structure of this utility model is compact and easy to integrate and install on the front end of the rock drilling rig. It meets the construction requirements in complex tunnel spaces while ensuring clamping stability.

[0020] The front support rod 1 has two fixing slots 101 and one first through slot 102 for precise installation and stable connection between the clamping device and the rock drilling rig body. The two fixing slots 101 are respectively located on the left and right sides of the front support rod 1 for fastening bolts to pass through. The clamping device is firmly fixed by connecting the bolts to the corresponding mounting base of the rock drilling rig body. The first through slot 102 is located at the center of the front support rod 1 for anchor cables or drill rods to pass through, facilitating continuous anchor cable advance and clamping operations. The two fixing slots 101 and the first through slot 102 are arranged in an isosceles triangle, which allows for a more reasonable force distribution during installation of the clamping device. This effectively resists off-center loads and torque interference under high-frequency impact and load variation conditions, ensuring clamping accuracy and structural stability. In addition, this arrangement also facilitates the automatic alignment of the clamp's central axis with the anchor cable construction axis, improving overall installation efficiency and the reliability of anchor cable support operations.

[0021] The connecting plate 2 has a second through slot 201 at its center. The second through slot 201 extends along the thickness direction of the connecting plate 2 and is coaxially arranged with the first through slot 102 on the lower front support rod 1 in the vertical direction. The two slots are the same size and perfectly aligned. This ensures that the piston rod 302 of the clamping cylinder 3 and the guide block 4 always perform clamping operations along the axis of the anchor cable or drill rod during movement, thereby avoiding clamping offset and inaccuracy. The connecting plate 2 has four fixing holes 202 symmetrically arranged on both sides. The fixing holes 202 are distributed on the left and right sides of the connecting plate 2 for fixing the clamping cylinder 3. Through the four-point evenly distributed fixing method, the clamping cylinder 3 can maintain a stable posture when subjected to lateral impact or axial load of the anchor cable, avoiding loosening or tilting, effectively improving the working reliability and load uniformity of the clamping mechanism. At the same time, it also facilitates quick on-site assembly and subsequent maintenance and replacement, enhancing the adaptability and practicality of the device.

[0022] The clamp cylinder 3 is evenly provided with four fixing blocks 301 around its circumference. The four fixing blocks 301 are symmetrically arranged around the clamp cylinder 3. Each fixing block 301 is connected to the fixing hole 202 on the connecting plate 2 by bolts, thereby realizing the stable installation of the clamp cylinder 3 on the connecting plate 2. This effectively prevents the cylinder from shaking or displacing due to vibration, impact or off-center load during operation, and improves the overall structural strength and positioning accuracy of the clamping device. The output end of the clamp cylinder 3 is provided with a piston rod 302.

[0023] The guide block 4 has a hole 401 at one end near the clamping cylinder 3. The hole 401 is a cylindrical through hole structure, and its axial direction is consistent with the output direction of the clamping cylinder 3. It provides linear guidance and limiting support for the extension and retraction of the piston rod 302, ensuring that the piston rod 302 does not wobble or shift laterally during reciprocating motion, thereby improving the action accuracy and service life of the clamping device. The front end of the piston rod 302 is inserted into the hole 401. The guide block 4 has a V-groove 402 at one end away from the clamping cylinder 3. The V-groove 402 extends along the axial direction of the guide block 4, and the groove opening has a symmetrical chamfered structure. The structure is designed to achieve multi-faceted contact and positioning of the anchor cable or drill rod when the clamp is closed, so that the anchor cable or drill rod is subjected to uniform force and strong stability in the clamping state, effectively preventing clamping deviation, slippage or damage, and helping to improve the adaptability and safety performance of the device under complex working conditions.

[0024] Working principle: During operation, the clamping cylinder 3, under hydraulic control, pushes the piston rod 302 to extend towards the center. The front end of the piston rod 302 is inserted into the guide block 4 and drives the guide block 4 to move. During the clamping process, the V-groove 402 of the guide block 4 achieves multi-point contact with the surface of the anchor cable, forming a stable wrapping support, effectively dispersing clamping stress and preventing slippage. The front support rod 1 and the connecting plate 2 provide stable support and a guiding path. The first through slot 102 and the second through slot 201 ensure that the clamping axis is aligned with the anchor. The cable construction axis is coaxial, improving clamping accuracy. After the rock drill drives in one anchor cable or drill rod, the anchor cable or drill rod passes through the anchor cable clamp device during the driving process. The anchor cable clamp device clamps and fixes the anchor cable or drill rod. The rock drill is then removed, and a second anchor cable or drill rod is installed at the front end of the rock drill. The drill is restarted, and the second anchor cable or drill rod is driven upward along the path. The second anchor cable or drill hole pushes against the first anchor cable or drill rod and is driven into the hole, realizing the advancement of the second anchor cable or drill rod. This cycle is repeated until the construction conditions are met.
