Description

Technical Field

[0001] The utility model relates to the technical field of pick positioning and installation, and particularly relates to a pick positioning and installation device. Background Technique

[0002] Picks are mainly used as drill bits for some mining machinery and need to ensure a certain hardness. During the production process of picks, a pick disc and a pick head need to be assembled together, and the assembled pick can be used. According to the needs of different working scenarios, the pick head will have an inclined angle after installation to be better used during rotation.

[0003] When positioning and installing the pick disc and the pick head, most of the existing methods are to adjust the angle of the ejector rod by workers using a torque wrench. Often, under the action of external forces, the adjusted angle will change, causing damage to the installation of the pick head. Moreover, the lifting device uses an externally exposed chain lifting method. This adjustment and lifting are not only time-consuming and laborious, but the externally exposed chain lifting will also pose a certain hazard to the operating personnel. Therefore, we provide a pick positioning and installation device to solve the above problems. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1-3 shown, the present invention provides a technical solution: a pick positioning and installation device, including a base 1 and a counterweight seat 18. A fixing frame 2 is fixed above the base 1. Grooves 5 are provided around the fixing frame 2. A movable block 7 is arranged on the surface of the fixing frame 2. A lifting motor 10 is arranged above the fixing frame 2. The output shaft of the lifting motor 10 passes through the inside of the fixing frame 2 and is fixed with a threaded column 6. A threaded block 9 is threadedly connected to the surface of the threaded column 6, and the threaded block 9 is fixed to the inner wall of the movable block 7 through the groove 5. The bottom end of the threaded column 6 is fixedly connected to a rotating shaft 4. A bearing 3 is sleeved on the surface of the rotating shaft 4, and the bottom end of the bearing 3 is fixed to the surface base 1. By using the lifting motor 10 and driving the movable block 7, the hydraulic push rod 11, the connecting block 13, the connecting plate 16 and the ejector rod 17 to move up and down by using the threaded connection between the threaded column 6 and the threaded block 9, corresponding adjustment can be made according to the thickness of the pick holder 20. At the same time, the embedded threaded up and down movement method is adopted to avoid the traditional chain type up and down movement, reducing the harm caused by the exposed chain to personnel;

[0023] A hydraulic push rod 11 is fixed to the side of the movable block 7. The other end of the hydraulic push rod 11 is fixed with a first motor 12 through a fixed disk. The output shaft of the first motor 12 is fixed with a connecting block 13. A second motor 14 is fixed on the connecting block 13. The output shaft of the second motor 14 is fixed with a connecting plate 16. One end of the connecting plate 16 is fixed with an extrusion motor 15. The output shaft of the extrusion motor 15 is fixed with a threaded rod 27. A ejector rod 17 is threadedly connected to the surface of the threaded rod 27, and the ejector rod 17 can extend out through the other end of the connecting plate 16. A limiting groove 25 is formed in the connecting plate 16. A limiting block 26 is arranged in the limiting groove 25, and the limiting block 26 is connected to the surface of the ejector rod 17. Guide wheels 8 are arranged on the surface of the movable block 7, and the guide wheels 8 are in contact with the surface of the fixed frame 2. By using the first motor 12 at the hydraulic push rod 11, the angle of the ejector rod 17 in the horizontal direction can be adjusted by the rotation angle of the motor. By using the second motor 14 at the connecting block 13 and the connecting plate 16, the angle of the ejector rod 17 in the vertical direction can be adjusted. At the same time, it is more labor-saving and time-saving compared with the traditional manual adjustment, and the adjusted angle is more accurate.

[0024] Specifically, as Figure 2 shown, the counterweight seat 18 is arranged above the base 1. A rotating motor 24 is arranged in the counterweight seat 18. The output shaft of the rotating motor 24 passes through and is fixed to the turntable 19. An annular groove 22 is formed between the bottom end of the turntable 19 and the counterweight seat 18. A sliding ball 23 is arranged inside the annular groove 22. A pick disc 20 is arranged on the turntable 19. A positioning rod 21 is arranged in the pick disc 20. The positioning rods 21 are distributed in a triangular shape in the pick disc 20, and the positioning rods 21 are movably connected to the turntable 19.

[0025] The above-mentioned annular groove 22 and balls 23 can cooperate in motion when the rotating motor 24 rotates, increasing the stability of the turntable 19 and the pick disc 20 on its surface. At the same time, the detachable positioning rods 21 used on the turntable 19 can fix the pick disc 20 on the surface of the turntable 19. The use of triangular fixation can increase the stability of the fixation.

[0026] Working principle: Before use, the staff places the pick disc 20 to be installed on the turntable 19 through an external overhead crane, and then installs the positioning rods 21 in a triangular shape inside the pick disc 20 to complete the fixation of the pick disc 20.

[0027] The staff then starts the lifting motor 10 through an external controller. The lifting motor 10 drives the threaded block 9 and the movable block 7 to move upward through the threaded column 6. After adjusting to the specified height, the hydraulic push rod 11 is controlled to push the connecting block 13 and the connecting plate 16 towards the position of the pick disc 20. The first motor 12 operates to drive the connecting block 13 and the connecting plate 16 to rotate, and adjusts the angle of the ejector rod 17 in the horizontal direction through the rotation angle of the first motor 12. The second motor 14 drives the connecting plate 16 to rotate to adjust the angle of the ejector rod 17 in the vertical direction;

[0028] After the angle is adjusted, the extrusion motor 15 is started to drive the threaded rod 27 to rotate. Under the cooperation of the limit groove 25 and the limit block 26, the ejector rod 17 is pushed outwards, and then the pick head placed on the pick disc 20 is extruded into the installation groove. The rotary motor 24 rotates, and under the cooperation of the annular groove 22 and the ball 23, the turntable 19 and the pick disc 20 are driven to rotate a certain angle, and then another pick head is installed on the pick disc 20 in the above manner.
