Description

Technical Field

[0001] This utility model relates to the field of top anchor drill rod operation construction technology, specifically a top anchor drill rod clamp. Background Technology

[0002] Top anchor drill rods are a key tool in underground mining, tunnel support and other engineering projects. They are used in conjunction with anchor drilling rigs to drill holes in the tunnel roof and install anchor rods to achieve effective roof support.

[0003] Currently, top-anchor drill rods require support from construction workers during tunneling operations, primarily to ensure drilling accuracy and improve overall construction efficiency. However, this support means the drill rod comes into direct contact with the worker's skin, which can easily cause skin damage and poses a certain risk. Therefore, a top-anchor drill rod holder that addresses these drawbacks is needed to improve the overall performance. Utility Model Content

[0006] The clamping mechanism includes a first clamping frame and a second clamping frame arranged symmetrically, and the first clamping frame and the second clamping frame are movably connected by symmetrically arranged hinges. A movable handle is fixed on one side of the outer surface of the first clamping frame and the second clamping frame.

[0007] Furthermore, the first clamping frame and the second clamping frame have openings on one side of their outer surfaces, and the inner walls of the openings fit together with the ends of the movable handles.

[0008] Furthermore, the first clamping frame and the second clamping frame are both provided with movable grooves at equal intervals at the middle position of their inner sides, and the movable grooves are provided with rolling frames, and the rolling frames are provided with rolling balls in the middle.

[0021] 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.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-4 As shown, this utility model is a top anchor drill rod clamp, comprising:

[0024] The clamping mechanism includes a first clamping frame 11 and a second clamping frame 12 arranged symmetrically, and the first clamping frame 11 and the second clamping frame 12 are movably connected by hinges 14 arranged symmetrically. A movable handle 13 is fixed on one side of the outer surface of the first clamping frame 11 and the second clamping frame 12.

[0025] The hinge 14 movably connects the first clamping frame 11 and the second clamping frame 12 to allow them to open and close. With the help of the movable handle 13, the force is applied to the surface of the top anchor drill rod when the first clamping frame 11 and the second clamping frame 12 act on the inner side, thus clamping and limiting the structure of the drill rod.

[0026] The first clamping frame 11 and the second clamping frame 12 have openings on one side of their outer surfaces, and the inner wall of the openings fits into the end of the movable handle 13.

[0027] The openings are designed to facilitate the structural docking and installation of the first clamping frame 11, the second clamping frame 12, and the movable handle 13.

[0028] The first clamping frame 11 and the second clamping frame 12 are both provided with movable grooves 18 at equal intervals in the middle of their inner sides, and the movable grooves 18 are provided with rolling frames 15 inside, and the rolling frames 15 are provided with rolling balls 17 in the middle of their inner sides.

[0029] The bottom end of the movable groove 18 is symmetrically provided with movable springs 16, and the upper end of the movable springs 16 is fixed to the bottom end of the rolling frame 15.

[0030] The movable slot 18 provides the space required for movement. The rolling frame 15 supports the ball bearing 17. By rolling the ball bearing 17 against the surface of the top anchor drill rod, the position of the clamp can be easily moved. Then, by utilizing the elasticity of the movable spring 16, the rolling frame 15 and the ball bearing 17 can be stored in the movable slot 18, ensuring that the inner sides of the first clamping frame 11 and the second clamping frame 12 are in contact with the surface of the top anchor drill rod, thus limiting their movement.

[0031] Working principle: During the support of the top anchor drill rod in the tunneling operation, a person wearing waterproof gloves uses the movable handle 13 to apply force to the first clamping frame 11 and the second clamping frame 12, so that the first clamping frame 11 and the second clamping frame 12 are in the unfolded state. After the first clamping frame 11 and the second clamping frame 12 are in the position outside the top anchor drill rod, a reverse force can be applied to close the first clamping frame 11 and the second clamping frame 12. By using the rolling of the ball bearing 17 and its surface, the position can be adjusted slightly in the opening and closing state of the clamp. After adjusting to the appropriate position, the first clamping frame 11 and the second clamping frame 12 are applied again to compress the movable spring 16, so that the rolling frame 15 and the ball bearing 17 extend into the movable groove 18, so that the inner side of the first clamping frame 11 and the second clamping frame 12 contacts the surface of the top anchor drill rod.

[0032] This solution replaces manual support and handling, reducing the risks associated with human operation and improving safety. Furthermore, its position can be adjusted with slight opening and closing, saving time and effort while improving efficiency.

[0033] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0034] It also includes an auxiliary clamping mechanism, which includes a cavity 21 opened in the middle of the movable handle 13, and the cavity 21 passes through the middle of opposite sides of the outer surface of the movable handle 13. A first sealing head 22 and a second sealing head 23 are respectively threaded in the middle cavity 21.

[0035] The cavity 21 can be filled with hot water to improve the comfort of use in cold weather. The first sealing head 22 and the second sealing head 23 seal the cavity 21 to prevent water from overflowing.

[0036] A sleeve post 24 is fitted at the middle of one end of the first sealing head 22, and a sleeve hole 25 is opened at the middle of one end of the second sealing head 23;

[0037] The interlocking of the sleeve post 24 and the sleeve hole 25 can structurally limit the set of movable handles 13 after control, that is, meet the structural limitation of the clamp in the retracted and unused state, reduce its probability of damage and its occupation of surrounding space.

[0038] Working principle: When using the clamp in extremely cold weather, hot water can be injected into the cavity 21 and sealed using the first sealing head 22 and the second sealing head 23. When the clamp is subsequently folded up, the first clamping frame 11 and the second clamping frame 12 are folded up, and the movable handle 13 is fixed by the interlocking of the sleeve post 24 of appropriate length and the sleeve hole 25, thus limiting the folded clamp.

[0039] This solution improves user comfort while reducing the space occupied by the clamp after storage and the probability of damage to the clamp itself, thus enhancing structural applicability and functionality.
