Description

Technical Field

[0001] The utility model relates to the technical field of blasting positioning, in particular to a blasting hole positioning and measuring device. Background Art

[0002] Bench blasting, also known as stepped blasting, refers to a method of rock blasting in the form of benches. Bench blasting is divided into deep-hole bench blasting and shallow-hole bench blasting according to different hole diameters and depths. Open-pit bench blasting is a basic means of mine production.

[0003] The existing patent document with the application number 202322654945.2 provides a quick positioning and measuring device for hole layout in bench blasting. Place the hole layout positioning and measuring device at a specific base point, adjust the support rod by adjusting the hydraulic cylinder, and at the same time observe the bubble level. Stop adjusting the support rod until the bubble level shows that the hole layout positioning and measuring device is level. Then rotate the turntable to align the alignment groove with a specific angle groove to determine the orientation of the hole layout. Then pull out the telescopic rod outward. Construction workers can perform positioning and measurement on the holes to be arranged through the scale. When the telescopic rod extends to a specific position, press down the pressure rod to make the paint in the paint bucket drip out for hole layout marking. This method of hole layout positioning and measurement is simple to operate, convenient and fast. Although the above application has many beneficial effects, there are still the following deficiencies: When the telescopic rod is moved outwards, manual operation is required, and the position of the telescopic rod cannot be limited after the operation. When the staff presses the paint bucket, force needs to be exerted, and the force borne by the paint bucket will be transmitted to the telescopic rod, easily causing the telescopic rod to displace, resulting in deviation of the positioned points. In addition, the paint bucket is directly arranged inside the placement rack, and it is prone to displacement and vibration when the whole device moves. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an object of the utility model is to provide a blasting hole positioning and measuring device. Through the cooperation of an electric motor, a rotating rod and a linkage rod, the telescopic plate can be mechanized to move outwards, and the position of the telescopic plate can be fixed by turning off the motor after the telescopic plate moves. It is convenient and fast to use, and does not require much manual participation, avoiding the phenomenon that the telescopic plate is prone to displacement when pressing the paint bucket. In addition, through the cooperation of a rotating ring, a fixing block and a pressing block, the paint bucket can be fixed inside the installation groove, preventing the paint bucket from displacing, vibrating and falling off inside the installation groove when the device moves. The overall structure of the utility model is simple, easy to use and has strong practicability.

Specific embodiments

[0019] Referring to Figures 1-5 , the blasting hole positioning and measuring device includes a base 1 and a paint bucket 2. A rotating seat 3 is rotatably connected to the base 1. A transmission mechanism 4 is provided at the top of the rotating seat 3. A multi-stage telescopic plate 5 is slidably connected inside the rotating seat 3. The top of the multi-stage telescopic plate 5 is fixedly connected to a first vertical rod 6;

[0020] The top of the multi-stage telescopic plate 5 is rotatably connected to a rotating ring 7. An array of multiple extrusion blocks 8 is fixedly connected to the inner circle of the rotating ring 7. An array of multiple mounting blocks 9 is fixedly connected to the top of the multi-stage telescopic plate 5 at a position corresponding to the inner circle of the rotating ring 7. A fixing block 10 is slidably connected inside each of the multiple mounting blocks 9. A connecting groove 11 is provided on each of the multiple fixing blocks 10. Symmetrically arranged springs 12 are fixedly connected to each of the multiple fixing blocks 10 at a position corresponding to the inside of the mounting block 9. An installation groove 13 is provided at the center position of the multi-stage telescopic plate 5 corresponding to the rotating ring 7;

[0021] The transmission mechanism 4 includes a mounting frame 41. An electric motor 42 is fixedly installed at the top of the mounting frame 41. The bottom end of the top wall of the mounting frame 41 is rotatably connected to a second vertical rod 43. A rotating rod 44 is fixedly connected to the second vertical rod 43. A connecting rod 45 is rotatably connected to the rotating rod 44. The electric motor 42 is convenient for driving the second vertical rod 43 to rotate.

[0022] Further, the output end of the electric motor 42 in the transmission mechanism 4 is rotatably connected to the top end of the second vertical rod 43. The mounting bracket 41 in the transmission mechanism 4 is fixedly connected to the top end of the rotating seat 3. The linkage rod 45 in the transmission mechanism 4 is rotatably connected to the first vertical rod 6.

[0023] Further, a plurality of symmetrically arranged electric telescopic rods 14 are fixedly connected to the base 1. The bottom ends of the electric telescopic rods 14 are fixedly connected with a chassis 15. The chassis 15 and the electric telescopic rods 14 facilitate providing stable support for the base 1.

[0024] Further, the paint bucket 2 is slidably connected inside the installation groove 13, which facilitates the disassembly of the paint bucket 2.

[0025] Further, the springs 12 are fixedly connected to the inner walls of the mounting blocks 9. One end of each extrusion block 8 is arc-shaped. The arc-shaped extrusion blocks 8 facilitate the extrusion of the fixing blocks 10 to move.

[0026] When the device is in use and the paint bucket 2 needs to be fixed, the rotating ring 7 can be directly rotated. The rotation of the rotating ring 7 will drive the extrusion blocks 8 to rotate together. The arc-shaped parts of the extrusion blocks 8 during rotation will extrude the arc-shaped parts of the fixing blocks 10. When the fixing blocks 10 are extruded, they will all move in the central direction. The movement of the fixing blocks 10 will squeeze and contract the springs 12. At this time, one end of the fixing block 10 will move to the top part of the paint bucket 2 to block the annular part on the paint bucket 2. When the arc-shaped parts of the extrusion blocks 8 rotate to the corresponding connection grooves 11, each extrusion block 8 will be connected to the inside of the connection groove 11. At this time, the paint bucket 2 is fixed. When disassembly is required, just rotate the rotating ring 7 forcefully. The extrusion blocks 8 will squeeze the inner wall of the connection groove 11. The squeezed fixing blocks 10 will still move. At this time, the extrusion blocks 8 are separated from the connection grooves 11, and the fixing blocks 10 will return to their original positions under the reset drive of the respective springs 12. At this time, the fixing of the paint bucket 2 is released;

[0027] When the multi-stage telescopic plate 5 needs to be extended outwards for positioning measurement and marking, the electric motor 42 can be started. The output end of the electric motor 42 will drive the second vertical rod 43 to rotate. The second vertical rod 43 will drive the rotating rod 44 to rotate together. When the rotating rod 44 rotates towards the linkage rod 45, it will squeeze the linkage rod 45. When the linkage rod 45 is squeezed, the connection part between the linkage rod 45 and the rotating rod 44 will rotate. At this time, the linkage rod 45 will transmit the force to the first vertical rod 6. At this time, the first vertical rod 6 will drive the multi-stage telescopic plate 5 to extend outwards. When the extension is completed, the electric motor 42 is turned off, as Figure 2 , at this time, the pressing plate on the paint bucket 2 can be pressed to make the paint bucket 2 spray paint to complete the positioning mark.
