In addition, the end that crossbeam sliding sleeve 9 is not set in crossbeam 1 also can be provided with cable 14, when this crossbeam 1 inside is provided with cable 14, as shown in Figure 5.
In this crossbeam 1 crossbeam sliding sleeve 9 is not set, one end of this cable 14 is that ring-type knots, be fixed on the inboard of the bottom of crossbeam 1 by buckle 15, be positioned at the link of this crossbeam 1 and another safety barrier elementary section, and between the bolt hole that this ring junction button bit is opened in this crossbeam 1 upper and lower end face, the inner space of the ring of formation greater than this bolt hole diameter;
The other end of this cable 14 is fixed in the crossbeam.
Because in this crossbeam sliding sleeve 9, crossbeam 1, and all be provided with cable in the base sliding rail 7, base sliding sleeve 8, and an end of cable 14 is set to ring-type and knots.As shown in Figure 6, the connection latch 17 that the ring junction button bit of this cable 14 is provided with on base sliding sleeve and crossbeam sliding sleeve and the position of bolt 18, the ring that is provided with in this base sliding rail and the crossbeam, with bolt hole that latch 17 and bolt 18 are connected between.
In this Fig. 6, when the safety barrier elementary section on the left of being positioned at is connected with the safety barrier elementary section that is positioned at the right side, the base sliding rail 7 of right-hand member that is arranged in the safety barrier elementary section in left side is not provided with base sliding sleeve 8, and the left-hand foot sliding rail 7 that is arranged in the safety barrier elementary section on right side is provided with base sliding sleeve 8.When the safety barrier elementary section on the left of being positioned at is connected with the safety barrier elementary section that is positioned at the right side, the crossbeam 1 of right-hand member that is arranged in the safety barrier elementary section in left side is not provided with crossbeam sliding sleeve 9, and the left side crossbeam 1 that is arranged in the safety barrier elementary section on right side is provided with crossbeam sliding sleeve 9.
And be positioned on the upper and lower end face of base sliding rail 7 of safety barrier elementary section on right side and have oval slotted hole, an end that is positioned at base sliding rail 7 at this base sliding sleeve 8 has supporting with it bolt hole, bolt 13 passes base sliding rail 7 and base sliding sleeve 8, be moved to the left in the oval slotted hole that bolt 13 has on this base sliding rail 7, drive this base sliding sleeve 8 and in this base sliding rail 7, be moved to the left.
The safety barrier elementary section on the adjacent right side of safety barrier elementary section in left side, the base sliding sleeve 8 in the safety barrier elementary section of right side move in the base sliding rail on safety barrier elementary section right side, left side.The base on safety barrier elementary section right side, left side slides to lead in the track base sliding sleeve is not set, but on the upper and lower end face of this base sliding rail, have bolt hole, and the base sliding sleeve 8 of the safety barrier elementary section on this right side, end outside being positioned at the base sliding rail 7 at its place has supporting bolt hole.
Therefore after the base sliding sleeve 8 of the safety barrier elementary section on this right side is moved to the left, bolt hole on this base sliding sleeve 8, when corresponding with the bolt hole position that has on the base sliding rail of left side safety barrier elementary section, and the base sliding rail bottom inside at the safety barrier elementary section in left side is provided with cable, the position of this cable is positioned at the inboard of this base sliding rail bottom, this ring-type buckle is between the screwed hole that has on this base sliding rail, and be provided with cable on the base of the safety barrier elementary section on this right side in the sliding sleeve 8, and this ring-type buckle is positioned at the inboard at these base sliding rail 8 tops, between the screwed hole that this base sliding rail 8 is that have with the safety barrier elementary section in left side is connected, therefore when adopting latch 17 to pass this left-hand foot sliding rail and right side base sliding sleeve, this latch 17 passes from two ring-type buckles, reach the upper surface of this base bottom, realization left side safety barrier elementary section is connected with right side safety barrier elementary section.
In addition, the bolt hole position that has on the base sliding rail of this left side safety barrier elementary section when being positioned at base inside, in order to realize connecting, also has the bolt hole that cooperates with it in the upper end of this base.
Equally, be positioned on the upper surface of crossbeam 1 of safety barrier elementary section on right side and have oval slotted hole, an end that is positioned at crossbeam 1 at this crossbeam sliding sleeve 9 has supporting with it bolt hole, bolt 12 passes the upper end and the crossbeam sliding sleeve 9 of crossbeam 1, with the bolt that is welded on these crossbeam sliding sleeve 9 upper base surface, be moved to the left in the oval slotted hole that bolt 12 has on this crossbeam 1, drive this crossbeam sliding sleeve 9 and in this crossbeam 1, be moved to the left.
The safety barrier elementary section on the adjacent right side of safety barrier elementary section in left side, the crossbeam sliding sleeve 9 in the safety barrier elementary section of right side move in the crossbeam on safety barrier elementary section right side, left side.In the crossbeam 1 on safety barrier elementary section right side, left side the crossbeam sliding sleeve is not set, but on the upper surface of this crossbeam, have bolt hole, and the crossbeam sliding sleeve 9 of the safety barrier elementary section on this right side, the end outside the crossbeam 1 that is positioned at its place has supporting bolt hole.
Therefore after the crossbeam sliding sleeve 9 of the safety barrier elementary section on this right side is moved to the left, bolt hole on this crossbeam sliding sleeve 9, when corresponding with the bolt hole position that has on the crossbeam of left side safety barrier elementary section, adopt bolt 18 to pass this left side crossbeam and right side crossbeam sliding sleeve 9, reach the soffit of this crossbeam bottom, fix this bolt 18 by nut, realization left side safety barrier elementary section is connected with right side safety barrier elementary section.
And because the right side crossbeam 1 of the safety barrier elementary section in this left side, and all be provided with cable in the left side crossbeam sliding sleeve 9 of the safety barrier elementary section on right side, after the crossbeam sliding sleeve 9 on right side moves to correspondence position, cable in the crossbeam of the safety barrier elementary section in this left side with, the coincidence that knots of the ring-type of the cable in the safety barrier elementary section crossbeam sliding sleeve of right side, and be positioned at the crossbeam 1 of safety barrier elementary section in the left side of connecting bolt 18, and between the bolt hole of right side safety barrier elementary section crossbeam sliding sleeve 9, in crossbeam during connection shown in Figure 6 and the crossbeam sliding sleeve ring-type knot with the drawing of site of the longitudinal section of bolt hole as shown in Figure 7, therefore when the different safety barrier elementary section of two of bolt 18 connections, the ring-type that bolt 18 can pass the cable 14 of these two coincidences knots, and is fixed on the soffit of this crossbeam 1 bottom by nut.
This cable can only be arranged in the crossbeam sliding sleeve, or be not provided with in the crossbeam of crossbeam sliding sleeve, in order to improve the reliability that connects between the different safety barrier elementary sections, in the crossbeam sliding sleeve reaches the crossbeam that the crossbeam sliding sleeve is not set, cable can be set all.
