Abstract
A shed beam laneway laser installing device mainly consists of a connection board, shed beam mounting brackets, a fixed screw cap and four connecting bars of a laser orientation instrument, wherein, the shed beam mounting brackets are fixed on the connection board by the fixed screw cap in parallel and symmetrically; four connecting bars of the laser orientation instrument are arranged below the connection board corresponding to four mounting holes on a lower planker of the laser orientation instrument, the end part of the connecting bar is provided with threads. When the utility model is in use, firstly, the end parts of the two shed beam mounting brackets are respectively provided with one end part of a screw cap to threads; secondly, the two shed beam mounting brackets are hung on a shed beam of the underground laneway of a mine; next, the end parts of the mounting brackets are passed by the holes on the connection board and are fixed by the fixed screw cap on the connection board; finally, the laser orientation instrument is fixed on the connecting bar by a nut and a gasket. The shed beam laneway laser installing device has simple structure and convenient manufacture and dismounting. The device is adopted to install the laser orientation instrument, thereby saving time, labor and materials, and the device has the uppermost point that the utility model can effectively make up the displacement error caused by the installation method of the prior art.
Description
One, technical field
The utility model relates to the device of hacking shed tunnel installation laser orientation instrument under a kind of coal mine.
Two, background technology
Laser orientation instrument is the instrument that direction is guided in tunnel commonly used under the coal mine, and tunnelling speed is very fast under the coal mine, especially combines pick team construction coal road, and the highest drilling depth reaches and advances about 600 meters by the single head moon, and laser down-hole range only reaches about 200m.Like this, the dismounting that we will be frequent, install laser with satisfy construction team in the tunnel, the requirement of stringcourse.Be on the capplce of tunnel, to fix it in the past when laser is installed with the iron wire bundle, this method should tie firm laser again to last tunnel center line very the difficulty, take a lot of work, time-consuming, the movability shakiness, precision does not satisfy the needs of producing, bring very big influence more for the construction of construction team, cause work efficiency low.
Three, summary of the invention
The technical problems to be solved in the utility model is: design a kind of laser erecting device, be used for laser orientation instrument is connected the capplce tunnel easily, to solve the problem that prior art exists.
Implementation procedure of the present utility model is: it mainly is made up of web joint, capplce fixed mount, hold-doun nut, laser orientation instrument connecting link, and the capplce fixed mount has two, is character, and two parallel symmetries are fixed on above the web joint with hold-doun nut; Corresponding to four mounting holes on the laser orientation instrument bottom plate, be provided with four laser orientation instrument connecting links on below web joint, there is screw thread the connecting link end, all has a limited block to be located at the top of screw thread on each connecting link.
Good effect of the present utility model is: simple in structure, and make, easy accessibility, but saved material again with this device installation laser orientation instrument time and labour saving, most importantly it can remedy the offset error that the installation method of prior art brings effectively.
Four, description of drawings
Accompanying drawing 1 is a front view of the present utility model; Accompanying drawing 2 is a vertical view; Accompanying drawing 3 is a side view.
Five, embodiment
The utility model is shown in accompanying drawing 1,2,3, it mainly is made up of web joint 1, capplce fixed mount 2, set bolt 3, laser orientation instrument connecting link 4, web joint 1 is the steel plate of 200 * a 150 * 6mm, four holes of four angular bits on web joint 1, capplce fixed mount 2 has two, be character, the end is provided with screw thread, and the hole that two parallel symmetries are passed on the web joint 1 is fixed on web joint 1 top with hold-doun nut 3; Corresponding to four mounting holes on the laser orientation instrument bottom plate, be welded with the laser orientation instrument connecting link 4 of four φ 16 * 150mm on below web joint 1, there is screw thread connecting link 4 ends, make limited block 5 on the top of screw thread on the available nut.
Using method of the present utility model is: earlier two capplce fixed mount 2 ends on each nut to the end of screw thread, two capplce fixed mounts 2 are hung on the capplce of colliery underworkings, the hole that the fixed mount end is passed on the web joint 1 is fixed on web joint 1 top with hold-doun nut 3 again; Then the mounting hole on the laser orientation instrument bottom plate is aimed at and penetrated laser orientation instrument connecting link 4, tighten instrument with nut and pad again.If there is the gradient in the tunnel, pad before and after can regulating guides stringcourse direction purpose in the tunnel to reach.
