[0031] Embodiment one

[0032] Please refer to Figures 1-8 The present application provides a technical solution: a vehicle-mounted deep well drilling machine, which comprises a vehicle frame connecting plate 1, the top right side of the vehicle frame connecting plate 1 is fixedly connected with a bracket support plate 3, the bracket support plate 3 is provided with four places, wherein every two longitudinally adjacent bracket support plates 3 form a group, and the inner sides of the two groups of bracket support plates 3 are both installed with a support guide plate 3011 through a connecting pin shaft 301;

[0033] There are two support guide plates 3011, and the right sides of the two support guide plates 3011 are fixedly connected to the drilling bracket 3012. The drilling bracket 3012 is a hollow frame structure, and the outer side of the drilling bracket 3012 is fixedly connected to the bracket mechanism 6. The bracket mechanism 6 is an L-shaped structure, and the right side of the bracket mechanism 6 is fixedly connected to the expansion push rod 601. The right output end of the expansion push rod 601 is fixedly connected to the bearing seat 6011. The left side of the outer peripheral surface of the bearing seat 6011 is fixedly connected to the guide support rod 6012 of the cylindrical structure. The side of the guide support rod 6012 away from the bearing seat 6011 is leftward. The side passes through the bracket mechanism 6, and a servo motor C7 is installed on the bottom end surface of the bearing seat 6011. The top end of the servo motor C7 is provided with an output shaft, and a guide rail mechanism 701 is installed on the output shaft. A slide groove is provided inside the guide rail mechanism 701, and two clamping push rods 7011 are fixedly connected to the inside of the slide groove in opposite directions. The inner side of the clamping push rod 7011 is fixedly connected to a moving block 7012. The top surface of the moving block 7012 is fixedly connected to a lifting push rod 7013. The lifting push rod 7013 is longitudinally arranged, and the top surface of the lifting push rod 7013 is fixedly connected to a support block assembly 7014. An extension push rod 7015 is fixedly connected to the left side of the support block assembly 7014, and an arc-shaped clamping portion 7016 is fixedly connected to the left side of the extension push rod 7015. The clamping portion 7016 is used to clamp the limit drilling rod. The main body of the frame connecting plate 1 is a U-shaped structure with an opening on the left side, and a cylindrical support pad 101 is fixedly connected to the bottom end surface of the frame connecting plate 1. There are four support pads 101 in total, and every two laterally adjacent support pads 101 form a group, and the two groups of support pads 101 are respectively fixedly connected to the front and rear sides of the bottom end surface of the frame connecting plate 1. The two groups of support pads The interior of 101 is provided with positioning holes 1011 that are through-holes in both directions on the upper and lower sides. The positioning holes 1011 are used for passing bolts for fixing. The bottom end surface of the interior of the drilling bracket 3012 is fixedly connected to the base plate mechanism 8, and the top surface of the base plate mechanism 8 is fixedly connected to the lifting push rod 801. The top of the lifting push rod 801 is provided with a slot, and the inside of the slot is rotatably connected to a driving gear 8011. The outer side of the driving gear 8011 is engaged with a multiplying chain 8012. The left end of the multiplying chain 8012 is connected to the base plate mechanism 8, and the right end of the multiplying chain 8012 is connected to the table assembly 4011.

[0034] In this embodiment, when multiple drill rods need to be carried to meet the requirements of continuous drilling operation, the rod temporary storage and transfer system of the device will operate in the following process. First, the L-shaped bracket mechanism 6 fixed outside the drilling support 3012 will serve as the basic support for the entire operation. The right side of the unfolding push rod 601 will be started first. The output end of the unfolding push rod 601 will extend to the right, driving the synchronous movement of the bearing seat 6011 fixedly connected thereto. The cylindrical structure guide rod 6012 on the left side of the outer circumferential surface of the bearing seat 6011 will pass through the reserved hole of the bracket mechanism 6 and slide stably along the straight line direction. This design can effectively prevent the bearing seat 6011 from deviating or shaking during movement, ensuring the accuracy of subsequent operations.

[0035] After the bearing seat 6011 moves to the appropriate position, the servo motor C7 installed on the bottom end surface thereof will start to work. The top end output shaft of the servo motor C7 will drive the guide rail mechanism 701 to rotate. By accurately adjusting the angle of the guide rail mechanism 701, the sliding groove inside the guide rail mechanism 701 and the drill rod to be grabbed will be in a corresponding orientation, preparing for the subsequent grabbing action. Subsequently, the two oppositely arranged clamping push rods 7011 inside the sliding groove of the guide rail mechanism 701 will be started simultaneously. They will respectively push the moving blocks 7012 connected on the inside to move relatively close or away along the sliding groove, thereby adjusting the lateral position of the lifting push rod 7013 on the top end of the moving block 7012, ensuring that the lifting push rod 7013 can align with the grabbing point of the drill rod.

[0036] When the lateral position adjustment is completed, the longitudinal lifting push rod 7013 on the top end of the moving block 7012 will be started. Its output end will extend upwards, driving the synchronous upward movement of the support block assembly 7014 on the top end, and then making the extension push rod 7015 and the arc-shaped clamping part 7016 connected on the left side of the support block assembly 7014 reach a height matching the drill rod to be grabbed. At this time, the extension push rod 7015 will start to work. Its output end will extend to the left, pushing the arc-shaped clamping part 7016 to gradually approach the drill rod, until the inner wall of the clamping part 7016 tightly fits the outer circumferential surface of the drill rod, completing the stable clamping of the drill rod.

[0037] After the drill rod is grabbed, the lifting push rod 7013 will first retract, lifting the drill rod to an appropriate height. Then the clamping push rod 7011 will reverse its action, driving the moving block 7012 to adjust its position. The servo motor C7 will also reverse the rotation of the guide rail mechanism 701, changing the orientation of the drill rod. Finally, the unfolding push rod 601 will retract, pulling the bearing seat 6011 and the drill rod back to the temporary storage area together, completing the temporary storage of the drill rod. When the drill rod needs to be replaced, all the above steps will be performed in reverse order, thereby realizing the quick retrieval of the drill rod. The entire process does not need to rely on additional transportation and assembly equipment, greatly improving the operation efficiency.

[0040] In this embodiment, in use, in order to ensure that the drilling support 3012 can be stable during operation and can be flexibly adjusted according to different drilling scenes, the support and adjustment system of the equipment will work together, first, the frame connecting plate 1 as the basis of the whole equipment will be connected with the vehicle chassis through the four support pads 101 at the bottom end of the frame connecting plate 1, the main body of the frame connecting plate 1 adopts a U-shaped structure with a left opening, which can better adapt to the shape of the vehicle chassis, and the four support pads 101 are divided into two groups, and each group of two horizontally adjacent support pads 101 is fixed on the front and rear sides of the bottom end face of the frame connecting plate 1. This distribution can make the stress of the frame connecting plate 1 more uniform, and the staff will pass the bolts through the positioning holes 1011 in the support pads 101, and fix the frame connecting plate 1 on the vehicle chassis, providing a stable basis for all subsequent operations;

This connection mode enables the drilling support 3012 to rotate around the connecting pin shaft 301, thereby providing the possibility of angle adjustment. Meanwhile, the two support bases 2 on the top end surface of the frame connecting plate 1 will further assist in the adjustment and fixation of the drilling support 3012. The support bases 2 are fixedly arranged on the front and rear sides of the top end surface of the frame connecting plate 1, and the shaft assembly 201 installed inside the support bases 2 is connected with the assembly plate 2011, and the side of the assembly plate 2011 away from the shaft assembly 201 is fixedly connected with the hydraulic rod 2012.

[0042] When it is necessary to adjust the angle of the drilling support 3012, the hydraulic rod 2012 will be started, and the output end thereof will exert a pushing force or a pulling force on the support base plates 2014 on the front and rear sides of the left end surface of the drilling support 3012 through the end splice plate 2013. Since the drilling support 3012 is movably connected with the bracket support plates 3 through the support guide plate 3011, under the action of the hydraulic rod 2012, the drilling support 3012 will rotate around the connecting pin shaft 301, thereby realizing the adjustment of the angle. After the drilling angle is adjusted to a proper angle, the hydraulic rod 2012 will maintain the current output state, and a stable force will be exerted on the drilling support 3012 through the splice plate 2013 and the support base plates 2014, so that the drilling support 3012 is stably maintained at the set angle, thereby avoiding the angle deviation due to vibration and other factors during the drilling operation, and ensuring the accuracy and safety of the drilling operation.
