The slot 11-1 may also be a rectangular slot with a slot opening length greater than the diameter of the cross beam 51.
The platform frame 2 comprises a connecting rod 21 and a second connecting rod 22; two connecting rods 21 are arranged and arranged on two sides in parallel; the connecting rod 22 is arranged between the two connecting rods 21; the connecting rods 21 and the connecting rods 22 form a rectangular frame structure, a plurality of adjusting holes 21-2 are formed in the side walls of the connecting rods 21, and a preset distance is formed between every two adjacent adjusting holes 21-2.
Specifically, the connecting rods 21 are plate-shaped structures, two connecting rods are arranged, the two connecting rods are respectively arranged on two sides and are parallel to each other, one end of each connecting rod 21 is provided with a hook 21-1, the hook 21-1 is arranged towards the direction close to the supporting body 1 and used for being hung on the ladder stand cross beam 5-1, the other end of each connecting rod 21 is fixed at the bending position of the bending structure 12-1 through an adjusting bolt 4, and the supporting body 1 and the platform frame 2 can be unfolded or folded by rotating the adjusting bolt 4. The side wall of the connecting rod 21 is also provided with a plurality of adjusting holes 21-2, and the adjusting holes 21-2 are circular holes which are arranged in equal parts and are used for being connected with the adjusting rods 3. The two connecting rods 22 are provided to connect the two connecting rods 21. The connecting rod 22 is a round steel, and two ends of the round steel are respectively welded with the inner side walls of the connecting rods 21 on two sides. The adjusting hole 21-2 may also be a rectangular hole, and the invention is not limited herein.
The hook 21-1 can be replaced by a connecting lug plate, and a lifting lug is welded at the use part to be connected with the connecting lug plate; if the width of the platform frame 2 needs to be increased, a conversion beam can be arranged at the rear parts of the hook 21-1 and the clamping groove 11-1 so as to increase the operation surface of the platform frame 2 and improve the stability of the platform.
The adjusting lever 3 is rotatably connected with the side walls of the support body 1 and the platform frame 2.
Wherein, adjusting rod 3 sets up two, is located the both sides of supporting body 1 and platform frame 2 respectively. The adjusting rod 3 is a turn buckle and a connecting lug plate, and the turn buckle is used for adjusting the length of the adjusting rod 3. Adjusting holes (11-2 and 12-2) at the lap joint of the supporting rods 11 and 12 are in bolt connection with an ear plate at one end of the adjusting rod 3, so that the adjusting rod 3 is rotatably connected with the supporting body 1; the ear plate at the other end is connected with the adjusting holes of the connecting rods 21-2 through bolts, the adjusting rod 3 is connected with different adjusting holes, and the opening angle between the supporting body 1 and the platform frame 2 can be adjusted, so that the ladder stand is suitable for ladder stands with different intervals, and the application range is enlarged. The turn buckle in the pole 3 is adjusted in the fastening after the platform mounting, can prevent effectively that the junction from rocking, improves platform stability.
In order to allow an operator to sit on the platform frame 2 smoothly and comfortably during construction, a plate-like material may be embedded in the platform frame 2 as a seat cushion.
The utility model provides a portable cat ladder and application method of platform thereof as follows:
firstly, a ladder chair in a folded state is bound with an operator through a rope, after the operator climbs the ladder to a specified height, the support body 1 and the platform frame 2 are opened by rotating the adjusting bolt 4, the hook 21-1 of the platform frame 2 is hooked on the cross beam 5-1, the clamping groove 11-1 on the support body 1 is clamped on the other cross beam 5-1 below, and finally, the opening angle between the support body 1 and the platform frame 2 is locked through the adjusting rod 3, so that the stability of the platform is improved. The overlapping length of the support body 1 (11/12) is adjusted to ensure that the platform frame surface is horizontal under different angles. So far, operating personnel can sit and be under construction on portable cat ladder platform.
In order to further enhance the safety during construction, an operator can use the safety rope together, the platform anti-falling rope is arranged to be connected with the ladder stand, and the locking mechanism can be arranged at the position of the hook 21-1 and the clamping groove 11-1, so that the safety of the platform is improved.
