Description

Technical Field

[0001] This utility model relates to the fields of mining machinery and engineering construction technology, and in particular to a drill bit picking and placing device. Background Technology

[0002] In mining, tunnel construction, and other fields, cutting tools (such as drill bits and drill rods) are high-frequency wear components that need to be replaced regularly to ensure operational efficiency. Currently, the main problems with cutting tool replacement are as follows: Manual replacement is inefficient: Traditional replacement relies on manual operation, requiring workers to manually disassemble the old drill bit and install the new drill bit after the machine is stopped. A single replacement of a single machine can take 10-15 minutes, which seriously affects the construction progress. Poor safety: The working environment is mostly high dust and high noise, and the cutting tools can weigh 50-100kg. Manual handling can easily lead to work-related injuries. At the same time, during the shutdown process, the equipment may be accidentally started, causing safety accidents. Disorganized storage management: New and scrap drill bits are often mixed together and there is no classified storage mechanism, which can easily lead to qualified drill bits being misjudged as scrap, increasing the cost of consumables. Limitations of existing automated equipment: Some automated replacement devices have complex structures, are only compatible with specific types of cutting tools, and have poor versatility; moreover, the lifting and telescopic mechanisms are not stable enough and are prone to falling off due to vibration. Utility Model Content

[0003] The main purpose of this utility model is to provide a tool picking and placing device to solve the problems of low efficiency, poor safety, insufficient versatility and chaotic storage of existing tools.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tool picking and placing device includes a column, a transport vehicle, multiple three-slot tool holders and a waste tool holder. A telescopic mechanism is fixedly installed at the upper end of the column, and a screw lifting mechanism is provided at the lower end of the telescopic mechanism. A bracket mechanism is also provided at the upper end of the transport vehicle.

[0008] Preferably, a mounting frame is fixed to the front end of the lifting plate, and multiple electromagnets are fixed to the lower end of the mounting frame.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1 As shown, a drill bit picking and placing device includes a column 1, a transport vehicle 2, multiple three-slot drill bit magazines 3 and a waste drill bit magazine 4. The upper end of the column 1 is fixedly installed with a telescopic mechanism 5 for horizontal movement, and the lower end of the telescopic mechanism 5 is provided with a screw lifting mechanism 6 for vertical lifting. The upper end of the transport vehicle 2 is also provided with a bracket mechanism 7 for assisting in the positioning of the drill bit.

[0016] like Figure 2 As shown, the telescopic mechanism 5 includes a base 51 with an opening in the middle. The base 51 is fixed to the upper end of the column 1. Two horizontal guide rails 52 are fixed parallel to each other on the upper end of the base 51. A horizontal slider 53 is slidably installed on the upper end of the two horizontal guide rails 52. A servo motor 54 is fixed to the upper end of the horizontal slider 53. A gear 55 is fixed to the output end of the servo motor 54. A rack 56 that meshes with the gear 55 is also fixed to the upper end of the base 51. When the servo motor 54 is working, the rack 56 can slide back and forth relative to the base 51 through the mutual meshing between the gear 55 and the rack 56.

[0017] Furthermore, to reduce dust on the surface of the horizontal guide rail 52 and extend the service life of the components, a telescopic cover is provided on the upper end of the base 51. The telescopic cover adopts a folding structure and can move and extend synchronously with the horizontal slider 53.

[0018] like Figure 3 As shown, the screw lifting mechanism 6 includes a guide plate 61 fixed to the lower end of the horizontal slider 53. The guide plate 61 is fixedly connected to the horizontal slider 53. When the horizontal slider 53 moves back and forth, it can drive the guide plate 61 to move back and forth. Two vertical guide rails 62 are fixed to the front end of the guide plate 61. A lifting plate 63 is slidably installed on the front end of the two vertical guide rails 62. The lifting plate 63 has grooves on both sides that match the vertical guide rails 62 to facilitate the up and down movement of the lifting plate 63. A drive motor 64 is fixed to the upper end of the horizontal slider 53. The output end of the drive motor 64 is fixed to a screw 65 that is threadedly connected to the lifting plate 63 through a reduction motor. When the screw 65 rotates, it can move the lifting plate 63 up and down. At the same time, the screw lifting design can prevent the lifting plate 63 from suddenly falling when the drive motor 64 loses power, thereby affecting the normal operation of the device and improving the safety of the device. In order to increase the stability of the screw 65 during operation, a support frame that is rotatably connected to the screw 65 is fixed to the lower part of the front end of the guide plate 61.

[0019] Furthermore, to facilitate the device's gripping of the drill bit, a mounting bracket 66 is fixed to the front end of the lifting plate 63, and multiple electromagnets 67 are fixed to the lower end of the mounting bracket 66. When the electromagnets 67 come into contact with the drill bit, they are energized and use their own magnetic force to grip the drill bit.

[0020] like Figure 4 As shown, the bracket mechanism 7 includes a four-bar linkage 71, which is a parallelogram structure. A hydraulic cylinder 72 is rotatably mounted on the upper end of the lower linkage of the four-bar linkage 71. The output end of the hydraulic cylinder 72 is rotatably connected to the inclined part of the four-bar linkage 71. Due to the inherent characteristics of the four-bar linkage 71, when the output end of the hydraulic cylinder 72 extends, it can allow the upper linkage to move horizontally upward. Multiple support plates 73 are fixed on the upper linkage, which can lift the drill bit for general drill bit picking and putting.

[0021] The specific implementation method for replacing the new drill bit in this embodiment is as follows: I. Initial Positioning After the equipment is started, the servo motor 54 of the telescopic mechanism 5 works, the gear 55 meshes with the rack 56, driving the horizontal slider 53 to move along the horizontal guide rail 52 to directly above the target bracket mechanism 7, and the telescopic cover extends synchronously with the horizontal slider 53. II. Grabbing the new drill bit When the drive motor 64 of the screw lifting mechanism 6 starts, the screw 65 rotates and drives the lifting plate 63 to descend along the vertical guide rail 62. After the mounting bracket 66 reaches the position of the drill bit, the electromagnet 67 is energized to generate attraction and attract the new drill bit. Then the drive motor 64 reverses and the lifting plate 63 rises to a safe height. 3. Move to the work station The telescopic mechanism 5 drives the mounting frame 66 to move to the drill bit mounting position of the equipment, the hydraulic cylinder 72 of the bracket mechanism 7 extends, and the four-bar linkage 71 drives the support plate 73 to rise, supporting the middle of the drill bit for auxiliary positioning. IV. Installation and Fixing The lead screw lifting mechanism 6 descends, inserts the new screw into the mounting hole, and the equipment automatically locks it in place; the electromagnet 67 is de-energized, the mounting bracket 66 resets, and the replacement is complete.

[0022] The specific implementation method for waste wire recycling in this embodiment is as follows: 1. Dismantle the old drill bit The telescopic mechanism 5 works in conjunction with the screw lifting mechanism 6 to move the mounting bracket 66 to the old rod position, the electromagnet 67 attracts the old rod, and the equipment is unlocked; the lifting plate 63 rises and pulls the old rod out of the mounting hole; II. Auxiliary Support The hydraulic cylinder 72 of the bracket mechanism 7 retracts, and the support plate 73 descends to below the old rod, supporting the old rod to prevent it from falling off; III. Categorized Storage The telescopic mechanism 5 moves the old rods to the top of the waste rod storage 4 for classification; the screw lifting mechanism 6 descends and puts the old rods into the corresponding compartment; the electromagnet 67 is de-energized, and the recycling is completed.
