Abstract
The utility model provides a detachable connecting device, which is used for developing the tunnels of mines or cutting the tunnels of road construction. With a fixed anchor rod and a chock, a laser orientation instrument can be fixedly connected conveniently, and the methods of cement casting and bolt fastening can be removed. The device has the advantages of simple structure, reliable use, flexible adjustment, convenient disassembly and assembly, less labor intensity for assembling the laser orientation instrument, time saving, quick construction progress, and convenient adjustment for the pointing position of the laser orientation instrument. The device can effectively exert the action of the laser orientation instrument and ensure the project quality.
Description
The utility model provides a kind of linkage of easy accessibility, particularly fixes the linkage of instruments such as the laser orientation instrument of various models or Laser Direction Pointer in tunnel or tunnel.
Along with science and technology development, adopt the new technology of laser alignment, be widely used in the mine development tunnel or the operation places such as digging the tunnel of building the road.The laser orientation instrument of the present various models of using, the structure that is used for fixing connection owing to equipment itself is inapplicable, brings many difficulties for installation, use.Existing connection way is in the tunnel or the assigned address in tunnel, and first perforating is put into fastening bolt again, reinforces with cement injection; Director could be connected on the fastening bolt after waiting to the cement solidifies.Not only labour intensity is big for this installation way, engineering time is long, and because director itself is very high to the accuracy requirement of installation site, the fixed-site of fastening bolt is more askew slightly, on the center line that just is difficult to make director be adjusted at the laser alignment requirement, so this makes director be difficult to be installed in appointed positions.In addition at the construction field (site), need the operating position of conversion laser orientation instrument, dismounting, installation be effort, time-consuming very, influences construction speed.For this reason, laser orientation instrument can not be applied widely, and this not only waste of manpower, material resources also lay up the waste that causes financial resources because of director.How to improve execution conditions, use laser orientation instrument better, solve the fixedly connected problem of laser orientation instrument as soon as possible, become the difficult problem of device fabrication producer and applying unit concern.
The purpose of this utility model provides a kind of linkage of easy accessibility.It not only saves time, laborsaving, improve service efficiency, and rotate flexibly, adjust freely.
The purpose of this utility model is achieved in that utilizes one and the corresponding junction plate of laser orientation instrument link, couple together by fixing anchor bar, chock, adapter sleeve, connecting rod, eyelet bolt and one or more fasteners, can laser orientation instrument be fixedly connected in tunnel or the tunnel easily, also because of rotating flexibly between each parts, can easily director be fixedly mounted on and point on the accurate position that requires simultaneously.
Because it is not the method that adopts traditional cement injection bolt that the utility model is fastened on assigned address with laser orientation instrument, but utilize directly fastening method of fixing anchor bar and chock, so easy accessibility, construction easily; This device adjustment is rapid flexibly in addition, therefore, can bring into play the effect of director effectively, improves workmanship and construction speed.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the utility model.
Fig. 2 is the partial sectional view of a kind of concrete structure of the utility model.
Fig. 3 is the vertical view that the utility model has the concrete structure of three hole junction plates.
Fig. 4 is the vertical view that the utility model has the concrete structure of four hole junction plates.
Fig. 5 is a kind of vertical view of laser orientation instrument concrete structure.
Fig. 6 is the scheme of installation that the utility model connects a kind of laser orientation instrument.
Describe concrete structure of the present utility model and operational circumstances in detail according to Fig. 1～6.This device comprises that fixing anchor bar 1, chock 2, an end have the adapter sleeve 4 that round boss and groove, the other end have the flat boss, the eyelet bolt 8 and the junction plate 10 that have the connecting rod 5 of cup head and have cup head, the connection between each parts adopt securing member to fix.When needs are installed laser orientation instrument in tunnel or tunnel, as long as get eyelet in the position of needs, fixing anchor bar 1 is inserted in the eyelet with hammer drill, reinforce with chock 2 again and get final product, without the filling of cement notes, can save a lot of times.The position of perforating replaces traditional three or four holes with a hole in addition, and the relative position in hole need not require so quite accurate, has also accelerated installation rate.Adapter sleeve 4 can be fixed on fixing anchor bar 1 and the connecting rod 5 by holding screw 3,7.The two ends of adapter sleeve 4 can reversing of position, fixedlys connected with fixing anchor bar 1, connecting rod 5 respectively (as shown in Fig. 1 and Fig. 2).Therefore, can adjust the sensing position of laser orientation instrument by the different link positions of adapter sleeve 4.The semicircle head end of connecting rod 5 and the semicircle head end of eyelet bolt 8 are connected and fixed by dogbolt 7.Utilize dogbolt 7 can adjust rotational angle between connecting rod 5 and the eyelet bolt 8 at an easy rate.Junction plate 10 utilizes two packing rings 9 to be sleeved on the eyelet bolt 8, and reinforces with nut 11.Junction plate 10 was realized with being connected by sleeve pipe 12 and connecting bolt 13 bars of laser orientation instrument.Because the laser orientation instrument model difference that each manufacturer makes, the structure of coupling part are also different.Generally speaking, adopt three or four connecting bolts 13 connections, therefore, junction plate 10 can be made the corresponding pattern with three holes or four holes according to the concrete pattern of laser orientation instrument syndeton.Slotted hole is made, so that adjust the sensing of laser orientation instrument at any time in the hole that joins with eyelet bolt 8 in the middle of the junction plate 10.Because each link mutual alignment of the utility model can be adjusted flexibly, so be easy to make laser orientation instrument to be fixed on the sensing position of appointment.When needing the installation site of conversion laser orientation instrument,, take out fixing anchor bar and get final product as long as chock 2 is got.Therefore, the utility model is not only easy for installation, and dismounting also is easy to.
The utility model is simple in structure, uses reliably, and easy accessibility is fixedly connected with laser orientation instrument as jockey except being used for, and also can be used to connect Laser Direction Pointer or Other Instruments.
Claims (2)
1, a kind of linkage of easy accessibility, comprise fixing anchor bar 1, chock 2, it is characterized in that adapter sleeve 4 two ends are connected with fixing anchor bar 1, connecting rod 5 respectively, and reinforce by holding screw 3,7, connecting rod 5 has an end of cup head and the semicircle head end of eyelet bolt 8, adopt dogbolt 6 to be connected and fixed, the junction plate 10 usefulness packing rings 9 of band connecting hole are sleeved on the eyelet bolt 8, reinforce by nut 11.
2, linkage according to claim 1 is characterized in that junction plate 10 is shaped on three or four connecting holes.
