Embodiment 1
[0030] refer to Figure 1-9 , a mine roadway roof and floor measuring device, comprising a base plate 1, a support column 2 is fixedly installed on the top of the base plate 1, a water supply and drainage mechanism 3 is installed on the support column 2, the water supply and drainage mechanism 3 includes a mounting plate 31, and one end of the mounting plate 31 An arc-shaped plate 32 is fixedly installed, and the arc-shaped plate 32 is sleeved on the support column 2. An arc-shaped ring 33 is fixedly installed on the outside of the arc-shaped plate 32 through bolts, and the arc-shaped ring 33 is sleeved on the support column 2. The mounting plate 31 A guide groove 34 is provided on the top, and a slide plate 35 is slidably installed in the guide groove 34, and a fixing bolt 36 is threaded on the slide plate 35. The mounting plate 31 is provided with several threaded holes 37 matched with the fixing bolt 36, and the slide plate 35 The outer end of the outer end is fixedly insta...
Embodiment 2
[0036] refer to Figure 1-9 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the transmission mechanism 4 includes a box body 41, the box body 41 is fixedly installed on the support column 2, and a rotating shaft 44 penetrating through the box body 41 is installed in rotation, A gear 43 is fixedly installed on the rotating shaft 44, and the gear 43 is arranged inside the box body 41. The extension transmission of the gear 43 is connected with a rack bar 42, and the rack bar 42 is slidingly connected with the box body 41. The top of the rack bar 42 is connected with the lifting The rod 5 is fixedly connected, and the outer end of the rotating shaft 44 is fixedly connected with the hand wheel 17 . The design of the transmission mechanism 4 functions in that the rack bar 42 and the gear 43 are driven by turning the hand wheel 17, so that the rack bar 42 drives the elevating bar 5 to slide up and down, thereby adjusting the heigh...
Embodiment 3
[0038] refer to Figure 1-9 , as another preferred embodiment of the present invention, the difference from Embodiment 1 or Embodiment 2 is that a number of reinforcing ribs 18 are fixedly installed between the support column 2 and the bottom plate 1, and the reinforcing ribs 18 can make the bottom plate 1 more stable and strengthen Ribs 18 The reinforcing ribs 18 are equidistantly distributed around the support column 2, and a positioning piece 19 is installed between two adjacent reinforcing ribs 18. The positioning piece 19 includes a hexagonal nut 191, and the bottom of the hexagonal nut 191 is a threaded rod 193. The threaded rod 193 and the hexagon socket nut 191 are integrally formed, and the extension thread of the threaded rod 193 is connected with a threaded seat 192 , and the threaded seat 192 is fixedly mounted on the bottom plate 1 .
