DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0031] like Figure 1 As shown, the blasting hole angle measuring device, as described:

[0032] The device comprises an adjusting mechanism 10, a protractor 11 is provided above the adjusting mechanism 10, and a measuring rod 12 is provided on the rear side of the protractor 11;

[0033] The expansion device includes two expansion rods 13, and the two expansion rods 13 are respectively arranged at the left and right sides of the measuring rod 12;

[0034] The drive device includes two push plates 22 . A drive slot 14 is provided on the top wall of the measuring rod 12 . Both push plates 22 are movably mounted in the cavity of the drive slot 14 .

[0035] It is worth noting that the adjustment mechanism 10, the protractor 11 and the measuring rod 12 have all been disclosed in a blasting hole angle measuring device for open-air deep hole blasting (202322953845.X), and will not be described in detail here.

[0036] During specific use, the expansion device can expand the two expansion rods 13 to the left and right sides to make its measured width equal to the blasting hole, so as to accurately measure the angle of the blasting hole. The driving device can drive the mechanical operation of the expansion device through the two push plates 22.

[0037] To sum up, by setting up an expansion device and a driving device, the measuring rod 12 can be expanded by the expansion device, so that its measuring width is aligned with the blasting hole, preventing measurement errors caused by width. The driving device can drive the expansion device to operate. Compared with the existing technology, it is easy to use and has a simple structure.

[0038] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a first through-hole 15 is provided on the left and right side walls of the two measuring rods 12, and the first through-hole 15 is communicated with the driving groove 14. A limit plate 17 is fixedly installed in an interlaced manner on the side wall where the two extension rods 13 are close to each other, and the two limit plates 17 are movably connected to the two corresponding first through-holes 15.

[0039] The left and right side walls of the measuring rod 12 are each provided with a second through-hole 16 connected to the driving groove 14 between the two first through-holes 15. Both push plates 22 can pass through the second through-hole 16. The side walls of the two push plates 22 that are away from each other are respectively fixedly connected to the side walls of the two extension rods 13 that are close to each other.

[0040] During specific use, the two first perforations 15 can both limit the expansion rod 13 through the limiting plate 17. When the two push plates 22 move to positions away from each other, the two expansion rods 13 can be driven to move to positions away from each other. During measurement, the side wall of the two expansion rods 13 away from each other is made to fit with the blasting hole for measurement.

[0041] To sum up, by setting the extension rod 13, the push plate 22, the first perforation 15 and the limit plate 17, the two push plates 22 can be moved to positions away from each other to drive the two extension rods 13 to move to positions away from each other. During measurement, accurate measurement can be performed by fitting the side wall of the two extension rods 13 away from each other to the blasting hole. It is easy to use and has a simple structure.

[0042] like Figure 5 As shown, the side walls of the two push plates 22 close to each other are fixedly installed with a driving plate 25 in a staggered manner, and the top walls of the two driving plates 25 are inclined from high to low from close to the push plate 22 to far away from the push plate 22.

[0043] Two limit blocks 24 are provided in the cavity of the driving groove 14. The limit blocks 24 are T-shaped. The front and rear ends of the two limit blocks 24 are fixedly connected to the front and rear side walls of the cavity of the driving groove 14 respectively. A spring 23 is fixedly installed on the side wall away from each other of the two limit blocks 24, and the ends of the two springs 23 away from each other are fixedly connected to the push plate 22.

[0044] A top plate 19 is fixedly installed on the top wall of the measuring rod 12, and a lifting plate 20 is provided in the cavity of the driving groove 14 above the two limit blocks 24. A bolt 18 is also provided above the measuring rod 12. The bolt 18 passes through the top plate 19 and the lifting plate 20 and is threadedly connected to the lifting plate 20.

[0045] The left and right ends of the bottom wall of the lifting plate 20 are fixedly installed with a supporting rod 21 in an staggered manner. The bottom walls of the two supporting rods 21 are both arc-shaped. The bottom walls of the two supporting rods 21 are both in contact with the two corresponding driving plates 25, and the front and rear side walls of the lifting plate 20 are both in contact with the front and rear side walls of the cavity of the driving groove 14.

[0046] When the bolt 18 is turned, the lifting plate 20 can be driven to move up and down by fitting the lifting plate 20 with the inner wall of the driving groove 14. The up and down movement of the lifting plate 20 can drive the push rod 21 to move up and down. When the push rod 21 moves downward, it can fit with the top wall of the driving plate 25. The inclined state of the top wall of the driving plate 25 makes the two driving plates 25 move to positions away from each other. The movement of the two driving plates 25 can drive the push plate 22 to move, and the push plate 22 drives the expansion rod 13 to move through the second through-hole 16. When the bolt 18 moves upward, the force of the two springs 23 can move the two push plates 22 to positions close to each other. The driving groove 14 can limit the limit block 24, and the limit block 24 can limit the spring 23.

[0047] To sum up, by setting the driving groove 14, the first through hole 15, the second through hole 16, the bolt 18, the top plate 19, the lifting plate 20, the push rod 21, the push plate 22, the spring 23, the limit block 24 and the driving plate 25, the two push rods 21 can be controlled to move by rotating the bolt 18, thereby moving the two push plates 22. It is easy to use and has a simple structure.
