[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 10 As shown, the present invention provides a drilling trolley positioning marking structure, including a main arm 1 and a drill rod mechanism 2 slidably arranged on the main arm 1, a guide groove 101 is arranged in the main arm 1, a propulsion mechanism 3 for driving the drill rod mechanism 2 to move is arranged in the guide groove 101, a propulsion beam positioner 4 is fixedly connected to the front end of the main arm 1, the propulsion beam positioner 4 is coaxially arranged with the drill rod mechanism 2, and a marking mechanism 5 is rotatably connected to one end of the main arm 1 close to the propulsion beam positioner 4, and the marking mechanism 5 includes a rotating plate 6, a positioning ring 7, a marking component 8 and an ink supply component 9 for conveying ink to the marking component 8, and the front end of the main arm 1 is symmetrically provided with Two positioning plates 13 and two rotating shafts are fixedly connected to the outer walls of the rotating plate 6 and are respectively rotatably connected to the two positioning plates 13. A rotating motor is installed on one of the positioning plates 13. The output shaft of the rotating motor passes through the positioning plate 13 and is fixedly connected to one of the rotating shafts. The positioning ring 7 is fixedly set on the rotating plate 6, the marking component 8 is fixedly set inside the positioning ring 7, and the ink supply component 9 is set on both sides of the front end of the main arm 1. The propulsion beam positioner 4 includes a limiting ring 41 and a fixed block 42. The fixed block 42 is fixed on the top of the main arm 1, the limiting ring 41 is fixed on the fixed block 42, and the positioning ring 7 is coaxial with the limiting ring 41.

[0034] A placement groove 11 capable of accommodating the positioning ring 7 and the rotating plate 6 is provided at the bottom of the main arm 1 .

[0035] In the present invention, before using the drill rod mechanism 2 to drill a hole, it is necessary to mark the drilling position. In the initial state, the marking mechanism 5 is vertically erected at a position above the front end of the main arm 1. When the drilling position needs to be marked, the main arm 1 is driven to move toward the working surface of the drilling until the ink supply component 9 conflicts with the working surface. At this time, the main arm 1 continues to move forward, so that the ink supply component 9 contracts under the pressure of the working surface, thereby transporting the ink stored inside it to the marking component 8 inside the positioning ring 7. At this time, the main arm 1 continues to drive the marking component 8 forward until the working surface conflicts with the marking component 8, so that the ink stained on its surface is printed on the working surface, thereby completing the marking work of the drilling hole, and then the rotating plate 6 is driven by the rotating motor to rotate clockwise, so that the marking component 8 is flipped until the marking component 8 is rotated to the inside of the placement groove 11 for storage. After the positioning ring 7 and the marking component 8 are flipped, the marked surface of the marking component 8 with ink faces upward, which can prevent the ink from flowing out. The present invention can independently perform the positioning operation of the drilling orientation, and after each drilling hole position is determined, the drilling operation is performed one by one, which is more convenient to determine the drilling hole position, avoids the staff manually marking the position resulting in inaccurate drilling position, and greatly improves the accuracy of drilling.

[0036] Furthermore, the marking assembly 8 includes a circular ring 81, a plurality of positioning rods 82 and an ink-coating member 83. The circular ring 81 is arranged at the middle position of the positioning ring 7. All the positioning rods 82 are evenly fixed on the outer circumference of the circular ring 81, and the ends of all the positioning rods 82 away from the circular ring 81 are fixedly connected to the inner side of the positioning ring 7. A first groove 84 is provided inside the circular ring 81, and a second groove 85 is provided inside all the positioning rods 82. The first groove 84 and all the second grooves 85 are filled with sponge bars 86. A receiving groove 87 connected to the first groove 84 and all the second grooves 85 is provided on one side of the outer wall of all the positioning rods 82 and the circular ring 81. The ink-coating member 83 is slidably arranged in the receiving groove 87. A liquid guide groove 88 is provided in the positioning ring 7, and one of the second grooves 85 is connected to the liquid guide groove 88. A through groove 89 connected to the liquid guide groove 88 and the inside of the rotating shaft is provided in the rotating plate 6.

[0037] The ink-repelling member 83 includes a shell 831 and a plurality of sponge strips 832. The shell 831 is slidably disposed in the accommodating groove 87. Baffles 833 are disposed on both sides of the shell 831. The baffles 833 are located in the first groove 84 and the second groove 85. All sponge strips 832 are filled in the shell 831 and extend to the outside of the shell 831.

[0038] The ink supply assembly 9 includes two pushing members 91 with the same structure. Liquid storage tanks 92 are provided on both sides inside the main arm 1. Active grooves 93 are provided on the inner walls of the two positioning plates 13, which extend into the inside of the main arm 1 and are connected with the two liquid storage tanks 92. The liquid storage tanks 92 are connected with the active grooves 93. The two pushing members 91 are slidably arranged in the two active grooves 93 respectively, and extend into the liquid storage tanks 92 adjacent thereto. A connecting groove 94 is connected between the two liquid storage tanks 92. An ink supply tube 95 is fixedly connected to one side of the outside of the main arm 1. One end of the ink supply tube 95 is connected to the connecting groove 94, and the other end is connected to another rotating shaft. A liquid storage tank 96 is also provided at the bottom of the main arm 1, and an infusion pump is connected between the liquid storage tank 96 and the connecting groove 94.

[0039] The ink in the liquid storage tank 96 is transported to the connecting groove 94 through the infusion pump, and the ink enters the liquid storage tank 92 through the connecting groove 94. Since one end of the ink delivery tube 95 is connected to the connecting groove 94 and the other end is connected to another rotating shaft, the ink in the liquid storage tank 92 enters the liquid guide groove 88 in the positioning ring 7 through the ink delivery tube 95 and the through groove 89. The ink can thus flow from the liquid guide groove 88 to the first groove 84 and the second groove 85, so that the sponge rod 86 inside the housing 831 absorbs the ink. Since the receiving groove 87 is connected to the first groove 84 and the second groove 85, the sponge strip 832 inside the housing 831 can fully absorb the ink. However, in order to avoid the rotating plate 6 driving the positioning ring 7 to rotate, the ink inside The ink flipping movement causes the ink to splash everywhere. Therefore, it is necessary to control the ink supply so that all the sponge rods 86 and sponge strips 832 are in a saturated state of adsorption during marking and to avoid the problem of excessive ink spillage. Before marking the marking assembly 8, the ink inside the liquid storage tank 96 needs to be transported to the first groove 84 and the second groove 85 through an infusion pump so that the sponge strip 832 inside the shell 831 can be fully adsorbed with the ink. A one-way valve is then set at the connecting groove 94 or the output end of the infusion pump to allow the liquid to flow back into the liquid storage tank 92 instead of returning to the infusion pump. A valve is also set on the ink delivery tube 95 to prevent a large amount of ink from entering the liquid guide groove 88 when the rotating plate 6 rotates.

[0040] Since the positioning ring 7 is in a vertical state in the initial state, that is, after the infusion pump delivers the ink to the liquid storage tank 92, the ink cannot enter the liquid guide groove 88 inside the positioning ring 7 through the ink delivery tube 95 when there is no pumping of the infusion pump. At this time, when the working surface conflicts with the pushing member 91, it can push the pushing member 91 to move, and the ink is delivered from the liquid storage tank 92 to the first groove 84 and the second groove 85; it is worth noting that only one of the second grooves 85 is connected to the liquid guide groove 88, and the second groove 85 is preferably located at the second groove 85 at the top of the middle part when the positioning ring 7 is vertically facing upward, so that the ink enters the second groove 85 when it reaches the top of the liquid guide groove 88.

[0041] Furthermore, the pushing member 91 includes a push rod 911, a push block 912, a sealing plug 913 and a spring 914. The push rod 911 is slidably connected in the movable groove 93. The sealing plug 913 is fixed at the end of the push rod 911 and is located in the liquid storage tank 92. The sealing plug 913 and the liquid storage tank 92 are axially sealed and slidably arranged. The push block 912 is fixed on the outer wall of the push rod 911, and the push rod 911 is located in the movable groove 93. The spring 914 is movably sleeved on the push rod 911, and the spring 914 is located in the movable groove 93, and one end of the spring 914 is in conflict with the push block 912.

[0042] When the main arm 1 moves close to the working surface that needs to be drilled, the push rod 911 first contacts the working surface, and as the main arm 1 continues to move close, the push rod 911 is pushed by the pressure from the working surface to compress the spring 914, and drives the sealing plug 913 to move along the inner wall of the liquid storage tank 92, so as to push out the ink inside, so that the ink enters the liquid guide groove 88 after passing through the ink delivery tube 95 and the connecting groove 94, and after the ink is transported to the top of the liquid guide groove 88, it enters the second groove 85 connected thereto, so that the ink enters the second groove 85 and the first groove 84 connected to the second groove 85, and then the sponge rod 86 and the sponge The strip 832 absorbs the ink inside it. When the end of the push rod 911 is pushed into the movable groove 93, the sponge strip 832 that absorbs the ink directly contacts the working surface, thereby completing the positioning mark of the required drilling position. The marking component 8 is composed of a circular ring 81 and multiple positioning rods 82. Correspondingly, the pattern printed by the ink is a ring and multiple straight lines. The pattern of the circular ring 81 is the identification position of the drilling hole, and the multiple straight lines can be used to compare the drilling position to prevent the subsequent drilling position from being offset. After the marking is completed, the main arm 1 moves away from the working surface after the marking, and the spring 914 drives the push rod 911 to reset after losing the extrusion force from the push block 912.

[0043] Among them, in order to prevent the length of the two push rods 911 from interfering with the rotation and storage of the positioning ring 7, a magnetic block can be set on the side of the movable groove 93 away from the push block. When the push block 912 moves to the magnetic block, it can be adsorbed and fixed. To release the fixed state of the push block 912, it is only necessary to close the valve on the ink supply tube 95 when the infusion pump supplies ink to the liquid storage tank 92. When the liquid in the liquid storage tank 92 increases, the sealing plug 913 and the push rod 911 can be pushed to reset, thereby driving the push block 912 to move and reset, so as to release the adsorption state of the magnetic block and the push block 912.

[0044] An air guide groove 411 is provided on the inner wall of the limiting ring 41, and a plurality of air outlets 412 are evenly provided along the circumferential direction on the outer wall of the limiting ring 41 facing the positioning ring 7, and all the air outlets 412 are connected to the air guide groove 411. An air pump 413 is installed on the outer wall of the main arm 1, and the output pipe of the air pump 413 passes through the fixed block 42 and is connected to the air guide groove 411.

[0045] An internal hollow wind guide plate 10 is fixedly connected between each adjacent positioning rod 82, and a plurality of exhaust ports 102 are provided on the side of all the wind guide plates 10 away from the limiting ring 41. A ventilation groove 103 is provided inside the circular ring 81, and all the wind guide plates 10 are connected with the ventilation grooves 103. A plurality of air ducts 104 compatible with all the air outlets 412 are evenly arranged along the circumferential direction on the outer wall of the circular ring 81 facing the limiting ring 41, and all the air ducts 104 are connected with the ventilation grooves 103.

[0046] When the rotating plate 6 drives the positioning ring 7 and the circular ring 81 to rotate until they conflict with the limit ring 41 on the propulsion beam locator 4, the multiple air ducts 104 outside the circular ring 81 are connected to all the air outlets 412. At this time, the air pump 413 is started to transport the gas to the inside of the air guide groove 411, and enter the air duct 104 through the multiple air outlets 412, and then enter the multiple air guide plates 10 from the ventilation groove 103. The gas is discharged from the multiple exhaust ports 102 on the surface of the air guide plate 10. At this time, after the working surface is fitted with the surface of the positioning ring 7, the marking component 8 is coated with ink and marked, and the gas is discharged from the exhaust port 102 and blown toward the working surface, thereby accelerating the drying speed of the ink and making the marked pattern clearer.

[0047] When the rotating plate 6 drives the marking assembly 8 inside the positioning ring 7 to rotate to the placement groove 11, the main arm 1 drives the drill rod mechanism 2 to approach the annular pattern marked on the working surface. The drill rod mechanism 2 includes a base 21, a drive motor 22, a drill rod body 23 and a guide sleeve 24. The base 21 is installed on the propulsion mechanism 3, the drive motor 22 is installed on the base 21, the drill rod body 23 is fixedly connected to the output shaft of the drive motor 22, the guide sleeve 24 is movably sleeved on the drill rod body 23, and the bottom of the guide sleeve 24 is fixedly connected to the base 21, and the guide sleeve 24 is coaxial with the limit ring 41. When the drill rod mechanism 2 is drilling, the propulsion mechanism 3 drives the drill rod mechanism 2 to move forward until the drill rod body 23 passes through the limit ring 41 inside the propulsion beam locator 4 and hits the marking pattern of the circular ring 81. At this time, the drive motor 22 drives the drill rod body 23 to rotate and drill. At this time, the air pump 413 is started synchronously, so that the gas is discharged from the gas outlet 412 to blow away the dust generated during drilling. The present invention is not only suitable for vertical drilling operations, but also for drilling operations that require a certain inclination under special terrain and geological conditions. It can accurately locate the drilling point and mark any position on the surface of the stone slab, thereby improving the accuracy and efficiency of drilling and facilitating the implementation of mechanized and fully automatic operations.

[0048] A camera 12 is installed on the side of the outer wall of the fixing block 42 facing the positioning ring 7. The camera 12 can be used to adjust the position of the drilling hole in real time, so that the drill rod body 23 is always located in the marked circular ring 81 pattern. With the use of the air pump 413, the dust generated during drilling can be prevented from blocking the monitoring screen of the camera 12.
