[0002] As a major support method for underground engineering and rock slopes, anchor bolts are widely used in highway and railway tunnels and mining roadways. With the development of anchor bolt support, the forms, types and specifications of anchor bolts are becoming more and more diverse. In order to obtain better support effects, the length requirements of anchor bolts are also increasing, and anchor bolt holes need to be drilled deeper.

[0003] At present, the drilling depth of drilling equipment on the market is mostly fixed length. When the required drilling depth exceeds the length of the drill rod, multiple drill rods need to be connected to drill the hole. At present, the rod connection operation for deep hole drilling is mainly done manually, that is, the anchor rod is manually sent into the rod connection position and then the rock drill is used to complete the rod connection action [1]. This not only has low overall construction efficiency, but also poses certain safety hazards. Utility Model Content

[0025] like Figures 1 to 3 The image shows a gripping device for connecting rock drilling rods, disclosed in this embodiment. It mainly includes a base 1, a tilting jaw 2, and an opening / closing jaw 3. The first end of the tilting jaw 2 is hinged to the base 1, and the first end of the opening / closing jaw 3 is hinged to the tilting jaw 2. The second end of the tilting jaw 2 and the second end of the opening / closing jaw 3 form a jaw 4 capable of gripping the drill rod 5. The clamping and releasing action of the drill rod 5 is achieved by opening and closing the jaw 4. The tilting jaw 2 can tilt on the base 1. With the tilting action of the tilting jaw 2, the drill rod 5 gripped on the jaw 4 can be sent into the connecting position, or the jaw 4 can be moved away from the connecting position, thus replacing manual connecting. This not only improves construction efficiency but also effectively ensures construction safety.

[0026] The base 1 includes two spaced-apart first side plates 101, with a stiffening plate 102 welded between the two first side plates 101. A connecting plate 103 is fixedly connected to the first end of the two first side plates 101, and the connecting plate 103 has multiple connecting holes 104. The connecting plate 103 and the connecting holes 104 together form a connecting structure, and the base 1 can be fixed to the side of the push beam with bolts.

[0027] The flipping gripper 2 includes two spaced-apart second side plates 201 and a connecting cylinder 202 fixedly connected to the bottom of the first ends of the two second side plates 201. The second ends of the two second side plates 201 together form the second end of the flipping gripper 2. The connecting cylinder 202 is hinged to the two first side plates 101 by a first pin 6, and the connecting cylinder 202 is located between the two first side plates 101, that is, the flipping gripper 2 is directly hinged to the base 1, which makes the gripping device structure more compact and reduces costs.

[0028] In practical implementation, the gripping device also includes a tilting drive unit 7. The first end of the tilting drive unit 7 is hinged to the outer wall of a first side plate 101 near its second end via a second pin 8. The second end of the tilting drive unit 7 is hinged to the outer wall of a second side plate 201 on the same side near its second end via a third pin 9. The tilting drive unit 7 has a telescopic stroke. As the tilting drive unit 7 extends and retracts, it drives the tilting gripper 2 to tilt on the base 1, thereby moving the drill rod 5 gripped on the jaws 4 into the rod receiving position or moving the jaws 4 away from the rod receiving position. The tilting drive unit 7 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc.

[0029] It is worth noting that in specific applications, the tilting gripper 2 is not limited to being driven by a tilting drive unit 7 with a telescopic stroke. Alternatively, the first pin 6 can be fixedly connected to the connecting cylinder 202, and after the first pin 6 is rotatedly engaged with the first side plate 101, the first pin 6 can be driven to rotate by a servo motor, hydraulic motor, or other power components, thereby causing the tilting gripper 2 to tilt.

[0030] In a preferred embodiment, a limiting member 10 is provided on the base 1, and the limiting member 10 is located on the downward path of the flipping gripper 2, thereby limiting the downward position of the flipping gripper 2, so that the drill rod 5 gripped on the jaws 4 can accurately fall onto the rod receiving station. More preferably, the height of the limiting member 10 on the base 1 is adjustable. For example, a bolt or screw bolted to the base 1 is used as the limiting member 10, so that the height of the limiting member 10 can be adjusted with the depth of the threaded connection. This allows the gripping device to adapt to the different push beams at each rod receiving station, and can also compensate for assembly errors of the gripping device on the push beam.

[0031] The opening and closing gripper 3 includes two L-shaped third side plates 301, which are located between two second side plates 201. The first ends of the two third side plates 301 are hinged to the two second side plates 201 via a fourth pin 11, and the second ends of the two third side plates 301 together form the second end of the opening and closing gripper 3. Optionally, the fourth pin 11 and the third pin 9 can be the same shaft or different shafts.

[0032] In practical implementation, the gripping device also includes an opening and closing drive unit 12. The first end of the opening and closing drive unit 12 is hinged to the first ends of the two second side plates 201 via a fifth pin 13, and the second end of the opening and closing drive unit 12 is hinged to the L-shaped bottom corners of the two third side plates 301 via a sixth pin 14. The opening and closing drive unit 12 has a telescopic stroke. As the opening and closing drive unit 12 extends and retracts, it drives the opening and closing gripper 3 to rotate around the fourth pin 11 on the flipping gripper 2, thereby realizing the opening and closing action of the jaws 4. The opening and closing drive unit 12 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc.

[0033] It is worth noting that in specific applications, the opening and closing gripper 3 is not limited to being driven to rotate by the opening and closing drive unit 12 with a telescopic stroke. Alternatively, the fourth pin 11 can be fixedly connected to the two third side plates 301, and the fourth pin 11 can be rotated in conjunction with the two second side plates 201. Then, a servo motor, hydraulic motor, or other power components can be used to drive the fourth pin 11 to rotate, thereby driving the opening and closing gripper 3 to rotate.

[0034] In the specific implementation process, a first clamping block 203 is fixedly clamped between the second ends of the two second side plates 201, and a second clamping block 302 is fixedly clamped between the second ends of the two third side plates 301. The jaws 4 are located between the first clamping block 203 and the second clamping block 302. The first clamping block 203 is fixedly connected to the two second side plates 201 by bolts or welding. Similarly, the second clamping block 302 is fixedly connected to the two third side plates 301 by bolts or welding.

[0035] In a preferred embodiment, arc-shaped grooves are provided on the side of the first clamping block 203 facing the second clamping block 302 and on the side of the second clamping block 302 facing the first clamping block 203, so that the first clamping block 203 and the second clamping block 302 can play a guiding role when gripping the drill rod 5, thereby improving the gripping stability of the drill rod 5.

[0036] The working process of the gripping device in this embodiment is as follows: First, the flipping drive unit 7 drives the flipping gripper 2 to tilt upward, so that the jaws 4 leave the receiving rod position, and the opening and closing drive unit 12 drives the jaws 4 to open. Then, the drill rod 5 is manually fed to the opened jaw 4, and the jaw 4 is then driven by the opening and closing drive unit 12 to clamp the drill rod 5. Subsequently, the flipping drive unit 7 drives the flipping jaw 2 to tilt downwards, so that the drill rod 5 on the jaw 4 falls into the rod receiving position; Finally, the jaws 4 are opened by the opening and closing drive unit 12, and after the drill pipe 5 is connected, the flip drive unit 7 is used again to drive the flipping jaws 2 to tilt upward.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
