Embodiment：
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
As Figure 1-4, a kind of roll adjustment alarm type rockbolt installation limiter, adjusted by limiter main body measurement 1, rock-bolt length
Section switch 2, ring-shaped conductor contact 3, audible and visible alarm fill 4, mobile contact 5, flexible measurement housing sliding rail 6, limiter main body
7th, rig 8, flexible measurement housing 9, limiter contact 10, anchor pole 11, spring conductor 12 form.
The limiter is provided with limiter main body 7 and flexible measurement housing 9；One is set in the limiter main body 7
Rock-bolt length adjusting switch 2, for adjusting the protruded length of anchor pole 11；The limiter main body measurement 1 is provided in limiter master
Measure scales on body 7, for setting the protruded length of anchor pole 11；One audible and visible alarm device is set in the limiter main body 7
4；A mobile contact 5 is set to be connected to rock-bolt length adjusting switch 2 in described device；One dilatability is set in described device
Amount housing 9 is connected to ring-shaped conductor contact 3；One flexible measurement housing sliding rail 6, measurement of stretching shell are set in described device
Body 9 can slide on sliding rail；One spring conductor 12 is set in described device through flexible measurement housing sliding rail 6
It is connected with mobile contact 5；By different degrees of pressure, audible and visible alarm when the spring conductor 12 contacts with ring-shaped conductor contact 3
Fill the alarm of 4 showed differents；Described device sets a limiter contact 10 to be connected as one with flexible measurement housing 9,
Limiter contact 10 touches rock mass wall, as flexible 9 one pieces of measurement housing is slided backward along flexible measurement housing sliding rail 6
It is dynamic；The flexible measurement housing 9 set in device can connect rig 8 and fix.
The ring-shaped conductor contact 3 is arranged in device to be connected to flexible measurement housing 9, with flexible measurement housing 9
Slide together.
The spring conductor 12 is connected through flexible measurement housing sliding rail 6 with mobile contact 5, spring conductor 12 and ring
When shape conductor contact 3 contacts, the loop of audible and visible alarm device 4, which is connected, shows the light less alarm of sound, with limiter contact
10 slide backward with flexible measurement housing 9, and the compression degree of spring conductor 12 increase, audible and visible alarm device 4 shows that dark sound is big
Alarm.
The anchor pole 11 is penetrated from device, and rock-bolt length adjusting switch 2 is set outside anchor pole 11 according to limiter main body measurement 1
Reveal length, rear end connection rig 8, when reach, limiter contact 10 and flexible measurement housing 9 are because stress is along flexible
Measurement housing sliding rail 6 is moved rearwards, and ring-shaped conductor contact 3 contacts with spring conductor 12 connects loop, and audible and visible alarm fills 4 hairs
Go out different alarms, workmen carries out construction adjustment, control anchor pole 11 to be pushed into depth in time according to different alarm sounds.
For operation principle of the present utility model as shown in figure 1, the anchor pole 11 penetrates from device, connection rig 8 in rear end is spacing
Device main body 7 connects rig 8 and fixed.Set anchor pole 11 exposed according to limiter main body measurement 1 by rock-bolt length adjusting switch 2
Length；It is the front view in maximum, minimum range of rock-bolt length adjusting switch 2 as Figure 2-3, is by the points of A shown in figure
Maximum range terminal in limiter main body measurement 1, B points are minimum range starting point in limiter main body measurement 1.
As shown in Figure 2 in minimum range, rock-bolt length adjusting switch 2 is moved to B points in limiter main body measurement 1, limit
Because stress is moved rearwards along flexible housing sliding rail 6 of measuring, ring-shaped conductor touches for position device contact 10 and flexible measurement housing 9
Piece 3 contacts with spring conductor 12 connects loop, and audible and visible alarm fills 4 and sends different alarms, and spring conductor 12 touches with ring-shaped conductor
When the rigid connection of piece 3 is touched, the loop of audible and visible alarm device 4, which is connected, shows the light less alarm of sound, and anchor pole 11 is pushed into speed of application drop
It is low, as limiter contact 10 and flexible measurement housing 9 slide backward, the increase of the compression degree of spring conductor 12, audible and visible alarm dress
The big alarm of 4 display dark color sound is put, the push-in construction of anchor pole 11 stops.Now rock-bolt length adjusting switch 2 and mobile contact 5 it
Between connecting rod known fixed spacing be L0, the rear end of anchor pole 11 connection rig 8 known fixed L3, it is solid known to limiter contact 10
Measured length L1, the flexible measurement known length of housing 9 be L2, limiter main body measurement LB, LA+L0=L2, so anchor pole protruded length
For Lmin=L1+L2+L3+LB(now LB=0)；
As shown in Figure 3 in maximum range, rock-bolt length adjusting switch 2 be moved to limiter main body measurement 1 in A points i.e.
LA, measurement of the stretching protruded length of housing 9 is L5、LA=L4=L5, so the protruded length of anchor pole 11 is Lmax=L1+L2+L3+L4Or
Lmax=L1+L2+L3+LA.Therefore anchor pole protruded length is L=L1+L2+L3+Li(LiThe quarter set for rock-bolt length adjusting switch 2
Angle value), therefore workmen pre-sets anchor pole 11 and fixes protruded length, is carried during constructing operation according to different alarms
Show, carry out construction adjustment, control anchor pole 11 to be pushed into depth in time.The accurate control that reconciles of anchor pole preset space is realized, is avoided
Anchor pole pierces too deep, improves the anchoring quality and anchoring efficiency of anchor pole.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
