According to the size of selecting montant and backup pad when preparation response support and auxiliary stand, select the rolling thorn cage of corresponding size, make guardrail integral erection more reasonable.

Step S022: a plurality of circular rings are arranged at specific positions of the rolling thorn cage at intervals.

Furthermore, a plurality of circular rings are arranged at specific positions of the rolling thorn cage at intervals and used for enabling the steel wire rope to pass through so as to fix the rolling thorn cage.

In this embodiment, as shown in fig. 7-9, the rolling cage 2 is placed at the top end of the wall 7, and rings 21 are arranged at intervals corresponding to the positions where the steel wire ropes 1 are arranged, so that the steel wire ropes 1 can pass through to fixedly connect the rolling cage 2, and when the rolling cage 2 is damaged, the steel wire ropes 1 vibrate or deform, so that the induction bracket 4 senses in time.

Step S2: the rolling thorn cage is connected with the induction bracket by a steel wire rope.

In the present embodiment, as shown in fig. 5, in step S2, the following sub-steps are included:

step S21: one end of the wire rope is fastened to the front end of a support rod.

In this step, one end of the aluminum Kong Gujin wire rope may be crimped with a tightener or the like.

When the tightener is installed, the bolt penetrates through a through hole at the front end of the supporting rod and a fixing hole corresponding to the tightener, and the tightener is fixed on the outer side of the supporting plate by using a nut.

When the steel wire rope is fixed, one end of the steel wire rope is loosened, passes through the threading hole on the tightener and passes through the hole on the cross arm of the tightener, the wire rope is clamped by the wire clamping pliers to pass through one end of the cross arm, and then the cross arm is rotated by the special spanner, so that the steel wire rope is tensioned and fixed on the cross arm of the tightener, and the sensing unit can sense vibration or deformation of the rolling cage and the steel wire rope in time.

As shown in fig. 13, a schematic structural view of a wire tensioner used in fig. 7 is shown. The wire tightener 3 is provided with a threading hole 31 through which the wire rope 1 passes, a fixing hole 32 for fixing it to the induction bracket 4, and a cross arm 33 for fixing the wire rope 1, and a fixing block 34 and a spring 35 for preventing the cross arm 33 from being reversed. The cross arm 33 is sleeved with a gear 332, the head of the fixed block 34 is in gear tooth contact with the gear 332, and one end of the spring 35 is in contact with the head of the fixed block 34 so as to limit the rotation direction of the cross arm 33.

Further, when the tightener 3 is mounted, the bolt passes through a through hole 411 at the front end of the supporting rod 41 and the corresponding fixing hole 32 of the tightener 3, and the tightener 3 is fixed to the outer side of the supporting plate 415 of the induction bracket 4, to which the fiber grating 414 is not attached, by using a nut. When the steel wire rope 1 is fixed, the steel wire rope 1 is firstly loosened, passes through the threading hole 31 on the tightener 3 and passes through the hole 331 on the cross arm 33 of the tightener 3, the wire rope 1 is clamped by the wire clamping pliers and passes through one end of the cross arm 33, and then the cross arm 33 is rotated by a special spanner, but due to the existence of the fixed block 34 and the spring 35, the cross arm 33 can only rotate in the direction away from the fixed block 34 and the spring 35, the situation that the cross arm 33 is slipped and overturned is prevented, the steel wire rope 1 is tensioned and fixed on the cross arm 33 of the tightener 3, and the sensing unit on the supporting rod 41 timely senses the vibration or deformation of the steel wire rope 1.

In the embodiment, for the supporting rod without the tightener, the steel wire rope can pass through the crimping aluminum buckle, and the crimping aluminum buckle is tightly pressed by the press machine, so that one end of the steel wire rope is fastened on the inner side or the outer side of the supporting rod, and the sensing unit can sense the vibration or deformation of the rolling cage and the steel wire rope in time.

As shown in fig. 14, for the auxiliary support 5 without the tightener 3, the steel wire rope 1 can pass through the crimping aluminum buckle 6, and the crimping aluminum buckle 6 is tightly compressed by a press machine, so that the steel wire rope 1 is fastened on the inner side of the support rod 51 of the auxiliary support 5, and a sensing unit on the sensing support 4 can sense vibration or deformation of the steel wire rope 1 in time.

Step S22: the rolling thorn cage and the induction bracket are connected by a steel wire rope.

In this embodiment, the step of connecting the roller cage and the induction bracket by using the wire rope includes: the other end of the steel wire rope penetrates through the circular ring arranged on the rolling thorn cage and the corresponding through hole on the supporting rod of the adjacent induction bracket, so that the rolling thorn cage is connected with the induction bracket for fixing, and the thorn cage sensing guardrail can be quickly assembled on site.

Further, if an auxiliary bracket is arranged between the induction brackets, after the other end of the steel wire rope passes through the circular ring on the rolling thorn cage, the steel wire rope passes through the through hole on the supporting rod of the auxiliary bracket, and simultaneously passes through the circular ring on the rolling thorn cage near the auxiliary bracket, and then the adjacent auxiliary brackets or the induction brackets are connected in the same way.

Step S23: the other end of the steel wire rope is fastened at the front end of the other supporting rod.

When the wire tightener is used for tightening one end of the steel wire rope, if the wire tightener is also used for tightening the other end of the steel wire rope, the specific operation of the step is consistent with that of the step S21, and details are not repeated here.

If crimp aluminum Kong Gujin is used at the other end of the wire rope, the tension of the wire rope needs to be detected before the crimp aluminum hole is fixed. Specifically, when one end of the steel wire rope is tightly wound by using a tightener, the tension of the steel wire rope is detected by a tension measuring instrument, and after the tension reaches a set value, the steel wire rope can be fixed by crimping an aluminum buckle. Therefore, the uniform tension value of the steel wire rope is determined, and the consistency of the sensing unit caused by the deformation of the steel wire rope is ensured.

When one end of the steel wire rope is fastened by using the crimping aluminum buckle, if the other end of the steel wire rope is also fastened by using the crimping aluminum buckle, the tension of the steel wire rope is also detected by a tension measuring instrument, and after the tension reaches a set value, the steel wire rope is fixed by the crimping aluminum buckle.

The fixing manner and effect of the crimp aluminum button are the same as those described in step S21, and will not be described here again.
