Description

Technical Field

[0001] The invention relates to the technical field of blasting and drilling, and in particular to a positioning and drilling device for blasting in a rockfill dam material field. Background Art

[0002] The positioning and drilling device for blasting in the rockfill dam material field is mainly used to accurately locate the drilling position at the dam site or material field for blasting operations. Through this device, the drilling depth, angle and spacing can be accurately controlled, thereby optimizing the blasting effect, reducing the impact on the surrounding environment, and improving the blasting efficiency and safety. Accurate drilling can effectively reduce the degree of stone fragmentation after blasting, reduce waste, and provide a good foundation for subsequent construction.

[0003] In actual work, the existing blasting positioning drilling device can basically meet the drilling needs of blasting in the rockfill dam material field, but there are still the following two problems: 1. In actual use, it is found that the existing positioning and drilling devices for blasting cannot adjust the drilling requirements according to the actual situation after being fixed. During operation, due to the lack of such adaptive adjustment function, the drilling position often deviates and cannot accurately match the ideal position of the blasting design. This not only greatly reduces the blasting effect, but also may increase the difficulty and cost of subsequent remedial work; 2. In actual use, it was found that the existing positioning and drilling devices for blasting could not be adjusted according to the road conditions at the blasting site during transportation, which greatly increased the difficulty of transporting the equipment. When transporting on bumpy roads, due to the lack of an effective response mechanism, the drilling components inside the equipment are easily damaged by vibration, which not only affects the normal use of the equipment, but may also lead to high maintenance costs.

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.

[0023] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a positioning and drilling device for blasting in a rockfill dam material field, comprising a supporting base plate 1, with outward expansion plates 2 fixed on both sides of the supporting base plate 1, with positioning components 6 fixed on the tops of the outward expansion plates 2, and drilling components 7 arranged between the positioning components 6.

[0024] The drilling assembly 7 includes a connecting column 71, and a second fixing plate 72 is fixed on the other side of the connecting column 71 away from the positioning assembly 6.

A movable slot 710 is provided on the third fixing plate 79, and a movable block 711 is slidably connected to the movable slot 710. Positioning holes 712 are evenly provided on the third fixing plate 79, and a fourth motor 74 is provided on the movable block 711. A drilling rod 75 is provided at the bottom of the fourth motor 74. The drilling assembly 7 fixes the second fixing plate 72 with the connecting column 71, and the positioning assembly 6 cooperates in drilling after positioning. The fifth motor 77 and the screw rod lock the support box 73 and the second fixing plate 72 to ensure the stable movement of the equipment. The movable block 711 slides in the movable slot 710 to adjust the left and right positions of the fourth motor 74 and the drilling rod 75, and the positioning holes 712 and the screws are used to fix the precise positioning. The fourth motor 74 drives the drilling rod 75 to rotate to complete the drilling, which can be flexibly adapted to the The support box 73 is provided with a screw rod 76 on both sides of the bottom of the third fixed plate 79, and a positioning lifting plate 78 is fixed at the bottom of the second lifting rod 76. The positioning lifting plate 78 is provided with a slot, and the drilling rod 75 passes through the slot provided on the positioning lifting plate 78. The outer ends of the support box 73 are provided with a screw rod, and the support box 73 is provided with a fifth motor 77 through the screw rod. The second lifting rod 76 on both sides of the bottom of the third fixed plate 79 can adjust the height of the positioning lifting plate 78 to meet the needs of fixing different drilling heights. The slot of the positioning lifting plate 78 provides accurate positioning for the drilling rod 75 to enhance the drilling stability. The support box 73 is connected to the second fixed plates 72 on both sides by means of the screw rod and the fifth motor 77. When the drilling angle needs to be adjusted, the support box 73 rotates on the second fixed plate 72 to drive the drilling rod 75 to change its angle as a whole to meet the diversified drilling needs.

[0025] Further, such as Figure 2 - Figure 3As shown: the positioning assembly 6 includes a support column 61, a first sliding groove 62 is provided on the support column 61, a sliding block 63 is slidably connected in the first sliding groove 62, a sixth motor 68 is arranged on the top of the support column 61, a first support plate 64 is fixed on the other side of the sliding block 63, a slot is provided on the first support plate 64, the first support plate 64 is slidably connected to the second base 66 through the slot, a third motor 65 is provided on the top of the second base 66, and a digging rod 67 is provided at the bottom of the second base 66. The support column 61 provides a stable supporting force for the equipment to ensure the stability of each component during work. The first sliding groove 62 and the sliding block 63 are connected to the first support plate 64. The sliding block 63 cooperates with the first sliding groove 62, and the sixth motor 68 drives the screw rod inside the first sliding groove 62 to rotate so that the sliding block 63 slides in the first sliding groove 62, thereby driving the first support plate 64 to perform lifting operations, and the second base 66 can slide in the slot on the first support plate 64, thereby driving the digging rod 67 at the bottom to slide, so as to achieve precise adjustment of the drilling position. The setting of the third motor 65 can drive the second base 66 to adjust the drilling position through the screw rod set on one side of the third motor 65 after the position is adjusted, so as to avoid displacement during the work process and improve the accuracy of positioning and the accuracy of drilling operations.

[0026] In order to solve the problem of equipment damage during drilling, such as Figure 4 As shown: In this solution, the anti-damage assembly 9 includes two second support plates 93, the two second support plates 93 are located at the bottom of the support box 73 and connected to the support bottom plate 1, and a fixing collar 94 is provided on the opposite side of the two second support plates 93, and an explosion-proof box 91 is provided inside the fixing collar 94, and an anti-damage cushion 92 is provided inside the explosion-proof box 91, and a folding anti-damage plate 95 is provided at the bottom of the explosion-proof box 91, and a dust guide plate 96 is provided at the bottom of the folding anti-damage plate 95, and a discharge port 97 is provided on the dust guide plate 96, and the second support plate 9 3 is fixedly connected to the bottom of the support box 73, and an explosion-proof box 91 is arranged in a fixed collar 94 at the bottom. When the positioning lifting plate 78 descends, the second supporting plate 93 is driven to descend, thereby causing the explosion-proof box 91 in the fixed collar 94 to descend, and the folding anti-damage plate 95 and the dust guide plate 96 at the bottom of the explosion-proof box 91 also descend accordingly, effectively protecting the bottom of the equipment. The anti-damage cushion 92 in the explosion-proof box 91 can buffer the impact of stones, and the stones after the impact are discharged through the discharge port 97 of the dust guide plate 96, avoiding blockage inside the equipment and ensuring stable operation of the equipment.

[0027] In order to solve the problem of difficulty in moving equipment on uneven roads, such as Figure 1 - Figure 5As shown: In this solution, a positioning base plate 3 is arranged at the bottom of the supporting base plate 1, and an auxiliary moving assembly 4 is arranged at the bottom of the positioning base plate 3. The auxiliary moving assembly 4 includes a first rotating shaft 41, a first lifting rod 42 is arranged at the bottom of the first rotating shaft 41, a rotating groove 43 is arranged at the bottom of the first lifting rod 42, a third rotating shaft 44 is arranged inside the rotating groove 43, the first lifting rod 42 is rotatably connected with the third rotating shaft 44, a first motor 45 is arranged at the bottom of the rotating groove 43, a second rotating shaft 46 is arranged inside the first motor 45, and hubs 47 are arranged on both sides of the second rotating shaft 46. A crawler track 48 is clamped on 47, and a first rotating shaft 41 is connected to a first lifting rod 42 at the bottom. The first lifting rod 42 can be flexibly adjusted by being rotatably connected to a third rotating shaft 44 in a rotating groove 43. A first motor 45 at the bottom of the rotating groove 43 drives the second rotating shaft 46 to rotate, thereby driving the wheel hubs 47 on both sides and the clamped crawler track 48 to move. The first lifting rod 42 can adjust the height of the crawler track 48 according to the site conditions. In a gravel site, the crawler track 48 increases the contact area with the ground, disperses the weight of the equipment, makes the equipment move more stably, and effectively avoids the shaking and sinking problems caused by gravel.

[0028] Working principle: like Figure 1 - Figure 6 As shown: When in use: the support column 61 serves as the basic supporting structure, laying the foundation for the normal operation of all components. Driven by the sixth motor 68, the screw in the first sliding groove 62 rotates to slide the sliding block 63, driving the first support plate 64 to rise and fall, thereby adjusting the height of the digging rod 67. The slot on the first support plate 64 provides a track for the sliding of the second base 66, thereby realizing the precise adjustment of the horizontal position of the digging rod 67. The third motor 65 can lock the equipment after positioning to prevent displacement, thereby greatly improving the positioning accuracy and drilling accuracy.

[0029] After the positioning is completed, the connecting column 71 ensures that the second fixed plate 72 is stable and is linked with the positioning component 6. After the positioning is completed, the drilling process is started. The fifth motor 77 cooperates with the screw rod to tightly fix the support box 73 and the second fixed plate 72 when the equipment moves, effectively enhancing the movement stability of the equipment and avoiding shaking damage. The moving block 711 slides in the moving slot 710 of the third fixed plate 79, flexibly adjusting the left and right positions of the fourth motor 74 and the drilling rod 75, and locking the moving block 711 with the help of the positioning hole 712 and the screw to ensure the accuracy of the drilling position. The fourth motor 74 drives the drilling rod 75 to rotate, efficiently completes the drilling task, and adapts to various drilling needs. The second lifting rod 76 can adjust the height of the positioning lifting plate 78 to match different drilling height requirements. The slot of the positioning lifting plate 78 is for accurate positioning of the drilling rod 75, enhancing the drilling stability, and the support box 73 can rotate on the second fixed plate 72 and be fixed with the help of the screw rod and the fifth motor 77 to achieve drilling angle adjustment to meet diverse drilling scenarios.

[0030] When drilling, the second support plate 93 is connected to the bottom of the support box 73, and the explosion-proof box 91 in the fixed ring 94 at the bottom rises and falls with the positioning lifting plate 78, driving the folding anti-damage plate 95 and the dust guide plate 96 to move synchronously, effectively protecting the bottom of the equipment, and the anti-damage cushion 92 buffers the impact of stones. The discharge port 97 of the dust guide plate 96 guides the stones after the impact to prevent blockage inside the equipment, ensure the stable and continuous operation of the equipment, and enable the entire equipment to maintain good performance and reliability in a complex drilling operation environment.

[0031] In terms of movement, the auxiliary moving component 4 and the moving component 5 ensure that the equipment can move stably under different road conditions. In the auxiliary moving component 4, the first motor 45 drives the track 48 to move, and the first lifting rod 42 can adjust the height of the track 48. In a gravel site, the track 48 enables the equipment to move stably. When used on ordinary roads, the universal wheel 51 allows the equipment to move conveniently. When encountering complex road conditions such as gravel sites, the screw 54 can be driven by the second motor 55 to retract the hollow column 53 into the first fixed plate 56, thereby retracting the connecting plate 52 and the universal wheel 51, and then moving through the auxiliary moving component 4 to ensure the stability of the equipment and realize the function of adjustment according to the road surface.

[0032] In addition, the supporting shell 8 protects the internal components, and the handle 10 facilitates the staff to operate and move the equipment, making the equipment operation more convenient and safer, and meeting the complex requirements of blasting and drilling in the rockfill dam material yard.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
