Description

Technical Field

[0001] This application relates to the field of engineering machinery and equipment technology, and in particular to a drill bit clamp. Background Technology

[0002] In engineering construction, mining, and geological exploration, drill rods are crucial tools. The ease and precision of their installation, fixing, and height adjustment directly impact overall construction efficiency and work quality. Drill rod clamps, as key equipment for holding and fixing drill rods, play an indispensable role in various rock drilling and crushing equipment.

[0003] However, currently available drill bit clamps have many shortcomings in height adjustment. Traditional drill bit clamp height adjustment relies heavily on manual operation, which is not only slow and difficult to adapt to the needs of rapid operations, but also has low adjustment accuracy, often failing to accurately match the required height position of the drill bit under different working conditions. More importantly, during the adjustment process, due to the lack of effective guiding and stabilizing mechanisms, the moving parts of the drill bit clamp are prone to displacement, shaking, or jamming. This not only affects the stability of the drill bit clamping, leading to safety hazards such as drill bit loosening and shaking during operation, but also prolongs auxiliary operation time and reduces overall work efficiency due to poor adjustment.

[0004] Furthermore, with the increasing demands for precision and efficiency in modern engineering, the requirements for drill rod height under different working conditions are becoming more diverse and sophisticated, making the shortcomings of traditional drill clamps in terms of adaptability increasingly apparent. How to achieve rapid and precise adjustment of the drill clamp height while ensuring the stability and reliability of the adjustment process has become a key issue in improving drill clamp performance and meeting actual operational needs. Therefore, developing a drill clamp capable of efficient and stable height adjustment is of significant practical importance for optimizing work processes, improving construction efficiency, and ensuring operational safety. Utility Model Content

[0005] One objective of this application is to provide a more efficient and stable rod clamp.

[0006] The technical solution adopted in this application is as follows: it includes a clamping mechanism and a telescopic mechanism; the telescopic mechanism is located below the clamping mechanism, and the telescopic mechanism includes a slide, a telescopic drive, a guide assembly, and a base; the clamping mechanism is mounted on the slide; one end of the telescopic drive is connected to the slide and the other end is connected to the base, and the telescopic drive is used to drive the slide to move relative to the base; the guide assembly is located between the slide and the base, and the guide assembly is used to guide the slide to move relative to the base.

[0007] Compared with the prior art, the advantages of this application are that the slide moves up and down by the telescopic drive component, which can quickly and accurately adjust the height of the clamping mechanism. The setting of the guide component further ensures the stability and trajectory accuracy of the slide movement, avoiding deviation or jamming during height adjustment, thus more reliably adapting to the requirements of the drill rod height under different working conditions. These features work together to significantly improve the overall work efficiency and ease of operation.

[0015] In some embodiments of this application, a top plate is provided on the base, and the top plate is used to support the base.

[0016] In some embodiments of this application, a protective plate is provided on the slide. The protective plate is used to protect the slide and prevent debris from entering the interior through the gaps at the edge of the slide, thereby avoiding debris accumulation that could cause the slide to jam or wear more severely and ensuring its smooth operation.

[0024] The technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1:

[0026] This embodiment provides a rod clamp, such as Figure 1-6As shown, the device includes a clamping mechanism 1 and a telescopic mechanism 2. The telescopic mechanism 2 is located below the clamping mechanism 1, and its core function is to provide height adjustment for the clamping mechanism 1. By changing its own height, it drives the clamping mechanism 1 to change position to adapt to the clamping position requirements of the drill bit under different working conditions. The telescopic mechanism 2 includes a slide 21, a telescopic drive component 22, a guide assembly 23, and a base 24. The clamping mechanism 1 is mounted on the slide 21, which serves as a support platform and can transmit the power of the telescopic mechanism 2 to the clamping mechanism 1, so that the clamping mechanism 1 changes position synchronously with the movement of the slide 21. The telescopic drive component 2... One end of the telescopic mechanism 2 is connected to the slide 21, and the other end is connected to the base 24. The telescopic drive 22 is the power source of the entire telescopic mechanism 2. The telescopic drive 22 is used to drive the slide 21 to move relative to the base 24. Through its telescopic action, the height of the slide 21 is precisely adjusted, thereby driving the clamping mechanism 1 to complete the position change. The guide component 23 is set between the slide 21 and the base 24. The guide component 23 is used to guide the slide 21 to move relative to the base 24, ensuring that the slide 21 moves smoothly along the preset trajectory during the movement, avoiding deviation, jamming, etc., and ensuring the accuracy and stability of the position adjustment of the clamping mechanism 1.

[0027] The aforementioned telescopic drive component 22 can be a pneumatic cylinder, an electric push rod, or a hydraulic cylinder: when a pneumatic cylinder or a hydraulic cylinder is used, its cylinder body is fixed to the bottom of the base 24, and the end of the piston rod is connected to the bottom surface of the slide table 21 through a flange; when an electric push rod is used, its fixed end is bolted to the side of the base 24, and the end of the push rod is hinged to the side of the slide table 21 to adapt to the installation requirements of linear drive.

[0028] Clamping mechanism 1 is used to clamp and release the drill bit. The core difference between its two structural forms lies in the integration of the jaw bearing structure:

[0029] Structure 1: A split-type gripper assembly design is adopted. The gripping mechanism 1 includes an independent gripper assembly 11 and a drive assembly 12. The gripper assembly 11 consists of a symmetrically arranged first gripper 111 and a second gripper 112. Both grippers have arc-shaped gripping portions machined on their inner sides to fit the outer circumference of the drill bit. The drive assembly 12 is correspondingly configured with a first drive member 121 and a second drive member 122, which are rigidly connected to the two grippers to drive their opening and closing. The working process is as follows: When the drill bit needs to be gripped, the first drive member 121 and the second drive member 122 act synchronously, and the piston rod extends to push the first gripper 111 and the second gripper 112 towards the center, using the arc-shaped gripping portions to adhere to the surface of the drill bit to achieve clamping; when releasing, the drive member piston rod retracts, driving the two grippers to move in the opposite direction to return to the open state.

[0030] Structure 2: An integrated clamp design is adopted. The clamping mechanism 1 includes an integrated clamp 11 (replacing the separate jaw assembly) and a drive assembly 12. The drive assembly 12 is symmetrically installed on the two side ears of the clamp 11. Its first drive member 121 is hinged to the first jaw 111 of the clamp 11, and its second drive member 122 is hinged to the second jaw 112 of the clamp 11. The extension and retraction of the drive members drives the entire clamp to complete the clamping and releasing actions. Its working process is as follows: When clamping, the piston rods of the first drive member 121 and the second drive member 122 extend synchronously, and the force is transmitted through the hinge point, causing the first jaw 111 and the second jaw 112 of the integrated clamp to rotate around the connecting shaft and move closer to each other to complete the clamping of the drill bit; when releasing, the piston rod of the drive member retracts, pulling the two jaws to rotate in opposite directions to open.

[0031] In both of the above structures, the first driving member 121 and the second driving member 122 can be hydraulic cylinders or pneumatic cylinders, and the driving stroke and clamping force can be adapted and adjusted according to the specifications of the drill bit.

[0032] The guide assembly 23 is disposed between the slide table 21 and the base 24. Its structure is based on the cooperation between the guide part 231 and the sliding engagement part 232: the base 24 has guide parts 231 on both sides, and the slide table 21 has corresponding sliding engagement parts 232 on both sides. The two form a sliding engagement to guide the slide table 21 to move smoothly. Specifically, the guide part 231 can be a guide rail, and the sliding engagement part 232 is a slider adapted to the guide rail. Through the sliding engagement between the guide rail and the slider, the smooth linear movement of the slide table 21 is further ensured.

[0033] Furthermore, the guide assembly 23 may be further equipped with a positioning mechanism 233. This mechanism includes a positioning element 2331 (which may be a positioning pin, spring pin, or bolt) disposed on the sliding mating part 232 and positioning holes 2332 formed in the guide part 231. Multiple positioning holes 2332 are spaced apart along the length of the guide rail. When the slide table 21 moves to the target position, the positioning element 2331 can cooperate with the corresponding positioning hole 2332 to achieve multi-position fixation of the slide table 21 on the guide part 231, significantly improving the working accuracy. This is especially suitable for drilling operations at different depths and other working conditions that require precise adjustment of the clamping position.

[0034] The base 24 is mounted on the propulsion beam, serving as the support structure for the entire telescopic mechanism 2. The guide assembly 23 ensures smooth and linear movement and prevents deviation through its guiding function. These features work together to make the adjustment of the drill rod height efficient and safe.

[0035] To optimize the movement range limitation of the slide table 21, a travel limit structure for the slide table 21 can be added: a limit seat 3 is provided at the upper end of the sliding mating part 232, and limit protrusions 4 are provided on the upper parts of both sides of the base 24. When the slide table 21 moves to the limit position, the limit seat 3 contacts the limit protrusions 4 to prevent the slide table 21 from detaching from the base 24 and improve the safety of the equipment.

[0036] This technical solution solves the problem of adjusting the position of the drill rod by setting a telescopic mechanism 2 below the clamping mechanism 1, thereby enabling the height of the clamping mechanism 1 to be adjustable. The telescopic drive component 22 drives the slide table 21 to move up and down, which can quickly and accurately adjust the height of the clamping mechanism 1. The guide component 23 further ensures the stability and trajectory accuracy of the slide table 21 during movement, avoiding deviation or jamming during height adjustment. The positioning mechanism 233 can achieve multi-position fixing, and the stroke limit structure improves safety, thus more reliably adapting to the requirements of drill rod height under different working conditions, significantly improving overall work efficiency and ease of operation.

[0037] The working process of this embodiment is as follows:

[0038] In the initial state, the slide 21 is at the foremost position of the base 24, and the two jaws of the clamping mechanism 1 are in the open state. When it is necessary to clamp the drill bit, the drill bit is placed between the two jaws, and the drive assembly 12 is activated. The piston rods of the first drive member 121 and the second drive member 122 extend synchronously, pushing the two jaws to close in the middle until the arc-shaped clamping part is tightly attached to the surface of the drill bit. After the set clamping force is reached, the action stops.

[0039] If the clamping position needs to be adjusted, the telescopic drive component 22 (taking a servo electric push rod as an example) is activated to drive the slide 21 to move along the linear guide rail 231 of the guide component 23. The displacement is monitored by the position sensor. After reaching the preset position, the slide can be fixed by the positioning mechanism 233. If it moves to the limit position, the limit seat 3 contacts the limit boss 4 to prevent the slide 21 from detaching from the base 24.

[0040] After the operation is completed, first control the cylinder piston rod of the drive assembly 12 to retract, so that the gripper opens to release the drill bit, and then control the telescopic drive 22 to drive the slide 21 to reset to the initial position.

[0041] The drill bit clamp of this embodiment can meet the clamping requirements of drill bits of different specifications, and features stable structure and flexible operation. By driving the slide table 21 up and down through the telescopic drive component 22, the height of the clamping mechanism 1 can be quickly and accurately adjusted to adapt to the requirements of drill bit height under different working conditions. No complicated auxiliary equipment and manual operation are required, which greatly improves the work efficiency.

[0042] Example 2:

[0043] This embodiment provides a rod clamp, such as Figure 1-4 As shown, based on Embodiment 1, this embodiment adds a top plate 5 to the base 24. The top plate 5 is detachably connected to the base 24 and is securely assembled with the base 24 by bolt assembly. The top plate 5 has a disc-shaped or columnar structure, and the surface of the top plate 5 is also provided with anti-slip texture. While supporting the base 24, it can increase the friction between the top plate 5 and the placement surface, thereby effectively improving the overall stability of the clamp during operation and avoiding tilting or displacement due to vibration or uneven force.

[0044] Example 3:

[0045] This embodiment provides a rod clamp, such as Figure 1-4 As shown, based on Embodiment 1, this embodiment adds protective measures: a protective plate 6 is added to the edge of the slide table 21. The protective plate 6 is detachably connected to the side surface of the slide table 21 by countersunk screws. One side fits against the side of the slide table 21, and the other side extends upward to form a shield. The protective plate 6 can cover the gap between the slide table 21 and the base 24. The protective plate 6 is used to protect the slide table 21. In the process of protecting the slide table 21, the protective plate 6 can effectively block external dust, debris, water stains and other debris from entering the moving parts inside the slide table 21 (such as the connection between the guide assembly 23 and the slide table 21) through the edge gaps. This avoids the accumulation of debris, which may cause problems such as jamming and increased wear when the slide table 21 moves, and ensures the smooth operation of the slide table 21.
