Specific implementation mode

Specific embodiment of the utility model is described in detail below with reference to attached drawing.

As shown in Figure 1, the utility model provides a kind of adjustable assembly type cat ladder of pedal angle comprising assemble successively One piece of a length of 300mm of thickness 5mm is arranged in the multistage cat ladder standard knot 1 of connection, in the present embodiment, every section of 1 lower part of cat ladder standard knot The second connecting rod (not shown), a part for the second connecting rod welds together with this section of cat ladder standard knot 1, the second connecting rod Another part on offer multiple bolts hole along its length, correspondingly, the top of next section of cat ladder standard knot 1 or pedestal On be also equipped with multiple bolts hole, multiple bolts pass through on bolt hole and next section of cat ladder standard knot 1 in the second connecting rod This section of cat ladder standard knot 1 and next section of cat ladder standard knot 1 are fixed together by multiple bolts hole.

See Fig. 2 and Fig. 3, every section of cat ladder standard knot 1 include be arranged cat ladder both sides side bar 10, be arranged in both sides side bar 10 Between first support bar 11 and second support bar 12 and the pedal that is arranged in first support bar 11 and second support bar 12 13.The both ends of first support bar 11 are hinged with both sides side bar 10 respectively, which is located at lower section side when being tilted away from side bar 10 Distance be 2-5cm, it is preferred that the distance that the hinge joint is located at lower section side when being tilted away from side bar 10 is 3cm.Specifically, A hole 100 is opened up at 10 downside 3cm of side bar, 11 both ends of first support bar are each passed through the hole on both sides side bar 10 100, the both ends of first support bar 11 are fixed by a pin on the side bar 10 of both sides.When side bar 10 and ground are at 45 °, phase The vertical interval between hinge joint on two sections of adjacent cat ladder standard knots 1 is 200mm.The bottom surface of pedal 13 and first support bar 11 are welded and fixed together, and rotate first support bar 11, and pedal is rotated as first support bar 11 rotates.

First through hole 101 is further opened on side bar 10, the both ends of second support bar 12 are each passed through first through hole 101 and two Side girders 10 connect, specifically, the maximum sloping coefficient and minimum sloping coefficient that may be met according to foundation pit in engineering, correspondingly Angle between pedal 13 and side bar 10 is referred to as maximum angle and minimum angles, first through hole 101 is opened in maximum angular The line segment 20 that the angle α that degree and minimum angles are formed is intercepted on the parallel lines 2 when being tilted away from side bar at upper side edge 2-5cm Place, in the present embodiment,

First through hole 101 is located at angle α that maximum angle and minimum angles the are formed upper side edge 3cm when being tilted away from side bar 10 At the line segment 20 intercepted on the parallel lines 2 at place, i.e., first through hole 101 is long stripes through hole.When in use, cat ladder is put into base In hole, rotation first support bar 11 is adjusted so that the pedal 13 in first support bar 11 and ground holding level further according to pedal 13 Position of the both ends of whole second support bar 12 in first through hole 101, the both ends of second support bar 12 are bolted on side On beam 10.The both ends of second support bar 12 shift in first through hole 101 in order to prevent, and the both ends of second support bar 12 are set respectively It is equipped with limiting device.See Fig. 3, which includes interlocking bar 3 and multiple gears for being arranged on side bar 10, in this implementation In example, multiple gear is that multiple second through-holes 102 highly to differ on side bar 10 are arranged.One end of interlocking bar 3 and second One end of supporting rod 12 connects, and the other end of interlocking bar 3 is also provided with bolt hole, the bolt hole accordingly with one in multiple gears A second through-hole 102 is bolted to connection so that the end side of second support bar 12 can be fixed on first by interlocking bar 3 leads to At position needed for hole 101.As shown in figure 4, being connected two-by-two by head rod 4 between adjacent interlocking bar 3, in this way may be used To realize that the interlocking bar 3 on each section of 1 side side bar 10 of cat ladder standard knot is disposably adjusted in place.The head rod 4 can be by growing The steel plate of 350mm wide 40mm thickness 10mm is made, the side that the interlocking bar 3 adjacent with two of head rod 4 can be connect by fastener Formula is fixed together.Pedal 13 is supported by first support bar 11 and second support bar 12, and first support bar 11 is cut with scissors with side bar 10 It connects, in order to enable pedal 13 is not easy to be kicked over, sees Fig. 5, the banking stop 5 of a U-shaped is welded on the center of 13 bottom surface of pedal, There is a third through-hole 50, second support bar 12 is passed through from third through-hole 50 is limited the limit of piece 5 wherein on banking stop 5.The The length of three through-holes 50 is with the equal length of first through hole 101 in order to which pedal 13 adjusts angle.

In order to improve the safety of cat ladder, it is equidistantly welded with more railings respectively on 10 upper side edge of side bar of cat ladder both sides 6, railing 6 is perpendicular to side bar 10 or railing 6 perpendicular to ground.In the present embodiment, 10 upper side edge of side bar is welded every 1.5m Basis of the steel pipe of the one a length of a diameter of 40mm of 200mm of section as railing 6.

In the cat ladder of application the present embodiment, first by multistage cat ladder standard knot assembly and connection so that it meets the depth of foundation pit Degree requires, and further according to the sloping coefficient of foundation pit, the first support of rotation 11 makes the pedal 13 in first support bar 11 horizontal, adjusts Saving position of the second support bar 12 in first through hole 101 makes pedal 13 in first support bar 11 and second support bar 12 Common support is lower to keep horizontal.More interlocking bar 3 for adjusting 12 both ends of second support bar again, after having adjusted, by every interlocking bar 3 Second through-hole 102 corresponded to on side bar 10 in multiple gears is bolted to connection, and entire adjustment process is completed.This Invention reaches adjustment pedal and side by the second support bar position of the interlocking bar control pedal bottom of multiple interconnections The purpose of beam angle so that cat ladder can be applied to the foundation pit of a variety of sloping coefficients, and be assembled by different lengths standard knot Cat ladder can meet different depth foundation pit, the base of the more sloping coefficients of more depth can be met under the premise of not removing cat ladder in this way Hole uses, and can be reused in multiple-project multiposition, while meeting personnel's vertical transport, also comply with safety construction standard The requirement on chemical industry ground.

The adjustable assembly type cat ladder of pedal angle according to the present utility model is described in an illustrative manner above with reference to attached drawing. It will be understood by those skilled in the art, however, that the adjustable assembly type of the pedal angle proposed for above-mentioned the utility model is climbed Ladder can also make various improvement on the basis of not departing from the utility model content.Therefore, the scope of protection of the utility model It should be determined by the content of appended claims.
