[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: Figures 1 to 3 As shown, a large hydraulic breaker drill rod assembly device includes a gantry 10, a slide 20 is provided on the gantry 10, a movable hanger 30 is slidably installed on the slide 20, the movable hanger 30 includes a fixed portion 39 that slides with the slide 20 and a mounting portion 310 for mounting a clamping mechanism, a lifting mechanism 311 is installed on the fixed portion 39, and the mounting portion 310 is driven up and down by the lifting mechanism 311. The lifting mechanism is a traditional lifting mechanism of a lifting screw pair driven by a motor, and the lifting mechanism 311 can realize the lifting and lowering of the clamping mechanism.

[0031] A clamping mechanism for clamping the drill rod is installed on the mounting portion 310 of the movable hanger 30. The clamping mechanism includes two symmetrically arranged clamping bodies 31. Mounting grooves 32 are provided on opposite sides of the two clamping bodies 31. A guide groove 1 33 and a guide groove 2 34 are provided on the groove wall of each mounting groove 32. The same clamping member 35 is installed in the guide groove 1 33 and the guide groove 2 34 on the groove wall of the same mounting groove 32. A reset member 36 (spring) installed on the groove wall of the mounting groove 32 is installed on the top of the clamping member 35.

[0032] The guide groove 1 33 includes an arc-shaped rotation area 331 and a vertically arranged sliding area 332. The guide groove 2 34 is vertically arranged, and two rotation nodes are provided on the clamping member 35. The two rotation nodes are respectively located inside the guide groove 1 33 and the guide groove 2 34.

[0033] When in use, the lifting mechanism 311 drives the clamping mechanism to move downward, and the clamping member 35 will first touch the drill rod. Under the non-working condition, the two rotation nodes of the clamping member 35 are respectively located inside the rotation area 331 and at the top of the guide groove 2 34. When the clamping member 35 touches the drill rod, its clamping member 35 will rotate outward along the rotation area 331 with the rotation node at the top of the guide groove 2 34 as the center, and compress the reset member 36. When the clamping member 35 moves down below the drill rod, the clamping member 35 will be reset under the action of the reset member 36 until the rotation node at the top enters the sliding area 332. Then, with the reverse movement of the lifting mechanism 311, the drill rod puts pressure on the clamping member 35, causing its clamping member 35 to move vertically along the sliding area and guide groove 2 34 until the rotation node is at the bottom of the two. At this time, it continues to follow the action of the lifting mechanism 311 until it moves together.

[0034] A drive mechanism is installed between the gantry 10 and the mobile hanger 30. The drive mechanism includes a bearing seat 12 mounted on the mobile hanger 30 and the gantry 10, a drive member 11 (motor) mounted on the gantry 10, a transmission screw 13 mounted on the output end of the drive member 11, the ends of the transmission screw 13 being rotatably mounted to the bearing seat 12, and a moving block 14 that matches the transmission screw 13 and is mounted on the mobile hanger 30. During use, the transmission screw 13 is driven by the drive member 11, which drives the moving block 14 and the mobile hanger 30 to move together, causing the clamping mechanism to move linearly along the slide 20, thereby transporting the drill rod and installing the drill rod into the mounting hole of the breaker cylinder.

[0035] Example 2

[0036] Based on the above embodiment, the following improvements are made: Figures 2 to 7As shown, the bottom surface of the clamping member 35 is provided with a roller 37, and the top surface of the bottom is provided with a supporting surface. The drill rod is guided without damage by the roller 37 at the bottom, and the drill rod is supported according to the supporting surface.

[0037] Example 3

[0038] Based on the above embodiment, the following improvements are made: Figures 4 to 7 As shown, the clamping mechanism also includes two guards 38 mounted on two clamping members 35 on the corresponding clamping body 31. Pressure wheels 312 are installed on both guards 38 via springs. The two guards 38 are connected by a rotating shaft and a torsion spring is provided at the rotating shaft. When the clamping member 35 moves downward and is subjected to pressure from the drill rod, the two guards 38 will expand to both sides. When the clamping member 35 passes through the drill rod, the guards 38 will be affected by the torsion spring and positioned. At the same time, the pressure wheels 312 on the drill rod apply pressure to the drill rod, so that the longitudinal direction of the drill rod is in a stable state. When the drill rod is installed in the corresponding mounting hole of the breaker cylinder, the clamping member 35 first moves downward for a distance under the action of the lifting mechanism 311, causing the supporting surface to separate from the drill rod. The driving mechanism is then started, and the mobile hanger 30 is moved laterally until the clamping mechanism is completely separated from the drill rod.

[0039] Example 4

[0040] Based on the above embodiment, the following improvement is made: multiple groups of the clamping mechanisms are arranged side by side on the mobile hanger 30.

[0041] Example 5

[0042] A device using any of the above embodiments, such as Figures 1 to 7 As shown, the process steps for assembling the drill rod are as follows:

[0043] First, the driving member 11 drives the transmission screw 13 to rotate and drives the moving block 14 and the moving hanger 30 to move along the slide rail to the drill rod;

[0044] Secondly, the lifting mechanism 311 drives the mounting portion 310 and the clamping mechanism to move downward, and the clamping member 35 on the clamping mechanism clamps the drill rod;

[0045] Next, the lifting mechanism 311 drives the mounting portion 310, the clamping mechanism and the drill rod in the reverse direction to move up to the height of the drill rod mounting hole in the breaker hammer cylinder. Then, the driving member 11 drives the transmission screw 13 in the reverse direction to install the drill rod into the breaker hammer cylinder.

[0046] Finally, install the drill pin and the stop pin on the drill pin.

[0047] Example 6

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
