Description
Technical field
The invention belongs to the anti-skidding anti-safety that breaks of colliery tunnel support technology more particularly to a kind of U-shaped steel canopy double flute clamping plate
Card cable suit and installation method.
Background technique
U-shaped steel canopy supporting have many advantages, such as bearing capacity is big, supporting time is long, it is easy to install, be unlikely to deform, be solve coal mine
The effective way of roadway support under complicated hard situation.Core component of the card cable as U-shaped steel canopy supporting, connection U-shaped steel are taken
The reliability of the part spreading degree (general 400mm or so) is the key that U-shaped steel canopy realizes effective support, it is therefore necessary to be met firm
Durable, safety and stability requirement.Routine card cable causes to adopt under complicated hard situation due to the various defects in design processing at present
When with U-shaped steel canopy supporting, phenomenon that set cap and canopy leg overlapping part generate changing of the relative positions sliding and nut or screw rod breaks, to draw
Send out Support Resistance not enough even serious consequences such as failure, large deformation of roadway.
Summary of the invention:
Technical problems to be solved by the inivention: provide a kind of U-shaped steel canopy double flute clamping plate anti-skidding anti-break safety card cable suit and installation
Method is easy with solving the existing tunnel under coal mine complexity hard situation using U-shaped steel bracket overlapping part when the supporting of U-shaped steel canopy
It generates changing of the relative positions sliding and nut or screw rod breaks phenomenon, to cause because Support Resistance is inadequate, or even failure causes the big change in tunnel
Shape, nut or screw rod break the technical issues of serious consequences such as hurting sb.'s feelings.
Inventive technique scheme:
A kind of anti-skidding anti-safety card cable suit that breaks of U-shaped steel canopy double flute clamping plate, it includes: upper limit card cable, middle infinite place card cable
With lower limit card cable；Upper limit card cable, middle infinite place card cable and lower limit card cable are separately mounted to U-shaped steel canopy overlapping part
Above, lower three positions are neutralized.
The middle infinite place card cable includes epiplastron and bottom web, and epiplastron and bottom web are high-strength by bolt and M27 type
Nut is fixedly connected；U-shaped steel canopy stent strut leg is fixed in the U-lag of bottom web, and U-shaped side plates is fixed on U-shaped steel canopy bracket
Between the U-lag and epiplastron of column leg.
The lower limit card cable includes epiplastron and bottom web, and epiplastron and bottom web pass through bolt and the high-strength spiral shell of M27 type
Mother is fixedly connected；U-shaped steel canopy stent strut leg is fixed in the U-lag of bottom web, and U-shaped side plates is fixed on U-shaped steel canopy stent strut
Between the U-lag and epiplastron of leg；Limit convex at two is provided on epiplastron and the epiplastron of U-shaped side plates lower end contact position
It rises；Back limits top beam lower end slide downward come retention bead when pressing.
Upper limit card cable includes epiplastron and bottom web, and epiplastron and bottom web are solid by bolt and M27 type high-strength nut
Fixed connection；U-shaped steel canopy stent strut leg is fixed in the U-lag of bottom web, and U-shaped side plates is fixed on the U of U-shaped steel canopy stent strut leg
Between shape slot and epiplastron；Retention bead at two is provided on bottom web at bottom web and U-shaped canopy column leg upper-end contact；Tunnel
Bottom plate limits column leg upper end upward sliding come retention bead when pressing.
The size of retention bead is high 5mm, wide 10mm.
A kind of installation method of the anti-skidding anti-safety card cable suit that breaks of U-shaped steel canopy double flute clamping plate, it includes:
Step 1 sets up U-shaped steel canopy, and canopy is away from 500mm, U-shaped side plates and column leg lap of splice 400mm, lap-joint from top to bottom
Install upper limit card cable, middle infinite place card cable and lower limit card cable totally three vice card cable, card cable spacing 170mm；
During step 2, frame canopy, it is desirable that canopy is away from deviation≤50mm, torque deviation≤50mm, U-shaped steel ceiling beam and column leg or so
Uneven deviation≤40mm, column leg legs and feet are erected on real bottom, and branch pull-rod nut is used and pulled between card cable M27 high-strength nut and canopy
Hand strap extension bar is tightened, and the Tightening moment of card cable M27 high-strength nut is 150~200N m.Advantageous effect of the invention:
The anti-skidding anti-card cable suit that breaks of U-shaped steel canopy double flute clamping plate is roughly the same with the construction technology that conventional card cable is set with, to taking
The two single u-shaped steel connect, first install the upper and lower web of card cable, then fixed with bolt；The difference is that being set with according to this card cable anti-skidding
Structural requirement, upper limit card cable, middle infinite place card cable and lower limit card cable are separately mounted to overlapping part upper, middle and lower portion, guarantee
The retention bead of upper and lower limits card cable is respectively against the upper end of column leg and the lower end of top beam, it is ensured that bottom plate and roof weighting time-division
Do not play the role of limiting overlapping part column leg upper end upward sliding and top beam lower end slide downward, improves working resistance of support.Together
When, the connection of card cable bolt uses M27 type high-strength nut.It efficiently solves since working resistance deficiency causes supporting effect not good enough
Even failure and nut or screw rod breaks the problem of hurting sb.'s feelings, and manufacturing process is simple, installs easy to operate, meets U-shaped steel bracket
Connection request has significant engineer application benefit.
