Problems solved by technology

Since the length of the fixed plate, the key component of the profilometer, is limited by carrying and transportation, the length of the contour curve drawn by the profilometer is limited. The maximum length of the surface contour curve of the rock mass structure that has been drawn so far Only 100cm, it is not convenient to study the roughness coefficient of large-scale rock mass structural surface

Embodiment 1

[0015] Such as figure 1 , 2 , shown in 4, a kind of large-scale profile curve fixed plate, is made up of several main boards 1 and the first connecting board 4 that can assemble each other, described main board, the first connecting board are respectively provided with mounting holes 2, and described main board The main board is closely connected with the main board along the long side direction to form a main board group. The connecting board is arranged at the joint of the main board, and the main board and the connecting board with the mounting holes aligned are fixed by bolts 3 . The effective length of the main board is 100cm, and the effective width is 20cm. There are two rows of mounting holes on the upper and lower sides; the distances between the first connecting plate and the left border along the long side are respectively 5cm, 15cm, 25cm, 35cm, 45cm, 55cm, 65cm, 75cm, 85cm and 95cm. 1. The second row of mounting holes in the lower row; the distances from the moun...

Embodiment 2

[0018] Such as figure 1 , 2 , 3, and 5, a large-scale contour curve fixed plate is composed of several mutually assembling main boards 1 and connecting plates, and the main board and the connecting plates are respectively provided with mounting holes 2, and the main board and the main board are arranged along the The main board group is closely connected in the long side direction, and the connecting board is arranged at the joint of the main board, and the main board and the connecting board with the mounting holes aligned are fixed by bolts 3 . Described connection plate comprises first connection plate 4 and second connection plate 5, and described first connection plate is arranged at mainboard butt joint, and described first connection plate is closely connected with first connection plate; Said second connection plate arranges At both ends of the main board group; the length of the main board group is equal to the sum of the lengths of the connected first connecting boa...

Abstract

The large scale profilogram fixing plate consists of several main plates and connecting plates assembled together. The main plates with installing holes are connected along the long side direction to form main plate combination, and the connecting plates also with installing holes are used for screw connection of the main plates. The large scale profilogram fixing plate has the advantages of simple structure, easy operation, convenient carrying and fast assembling, and may be used in drawing large scale rock body structure surface profilogram effectively.

Description

(1) Technical field [0001] The invention relates to a large-scale contour curve fixing plate, which is suitable for drawing a large-scale contour curve on the surface of a rock mass structural surface with any occurrence in the field. (2) Background technology [0002] In the prior art, the surface profile curve drawing method of the rock mass discontinuity surface with a sampling length of 200cm, 300cm, 400cm, 500cm, 600cm, 700cm, 800cm, 900cm or 1000cm stays in theory, namely using a profiler for drawing. Since the length of the fixed plate, the key component of the profilometer, is limited by carrying and transportation, the length of the contour curve drawn by the profilometer is limited. The maximum length of the surface contour curve of the rock mass structure that has been drawn so far It is only 100cm, which is not convenient for studying the roughness coefficient of large-scale rock mass discontinuities. (3) Contents of the invention [0003] The purpose of the p...
