The construction of buildings and the decoration of external walls all need construction operation boxes. People and goods are in the construction operation box. Safety is of great importance. In everyday situations, construction cabinets often lack safety devices. Once the rope of the traction construction operation box is broken, life casualties and equipment damage accidents can be caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing the safety device of construction operation case in order to overcome above-mentioned weak point, even take place to pull the cracked condition of rope of construction operation case, can not cause the casualties, the accident of equipment destruction yet.

The utility model provides a technical scheme that its technical problem adopted is: the safety device of construction operation box is mounted on one side surface of the construction operation box. It is composed of two parts of a braking mechanism and a vertical sliding track mechanism. The structure of the brake mechanism is described first: a shaft pin is arranged on a flat plate, and a movable rod is sleeved on the shaft pin. A gap is arranged between the shaft pin and the movable rod, and the movable rod can rotate around the shaft pin. The movable rod is provided with a tension spring, and the other end of the tension spring is connected to the flat plate. Under normal circumstances, the movable rod is obliquely arranged on the support block. The wing pieces are respectively arranged on two side surfaces of the lower end of the movable rod. The upper end of the movable rod is provided with a bending head, and the end surface of the bending head is a plane. The flat plate is fixed with a stop block, and the distance between the lower end of the bending head and the upper plane of the stop block is 10-30 mm. Extension arms are connected with two sides of the flat plate through screws and extend out leftwards. The left end of the extension arm is provided with a sliding block. The structure of the vertical sliding track mechanism is described again: the fixed mechanism is planted on the ground, a vertical track is arranged in the fixed mechanism, a gap is reserved between the track and a sliding block at the left end of an extension arm, and the sliding block slides up and down in the track and drives the extension arm and a brake mechanism to move up and down. Spaced flanges are provided on the right side of the vertical slide rail mechanism facing the movable rod in the brake mechanism. When the traction rope is broken, the construction operation box falls rapidly, due to the air damping effect of the fins on the two side faces of the lower end of the movable rod, the movable rod overcomes the tension of the tension spring, the movable rod rotates clockwise around the shaft pin, when the lower plane of the bending head at the upper end of the movable rod abuts against the upper plane of the stop block on the flat plate, the lower end head of the movable rod is clamped on the flange, the whole construction operation box is hung on the vertical sliding track mechanism and is not prone to falling, and therefore accidents of personal casualties and equipment damage are avoided.

The effective effect of the utility model is, use the utility model discloses a construction operation box's safety device even take place to pull the cracked condition of rope of construction operation box, can not cause the accident of personal casualties, equipment destruction yet.

Detailed Description

The safety device of construction operation box is mounted on one side surface of the construction operation box. It is composed of two parts of a braking mechanism and a vertical sliding track mechanism. The structure of the brake mechanism is described first: a shaft pin (4) is arranged on a flat plate (7), and the diameter of the shaft pin (4) is 6 mm. The flat plate (7) is a low carbon steel plate, and has a thickness of 3mm, a length of 220mm and a width of 200 mm. The shaft pin (4) is sleeved with a movable rod (6). A gap is reserved between the shaft pin (4) and the movable rod (6), and the movable rod (6) can rotate around the shaft pin (4). The shaft pin (4) and the movable rod (6) are made of carbon steel. The movable rod (6) is provided with a tension spring (3), and the other end of the tension spring (3) is connected to the flat plate (7). Under normal conditions, the movable rod (6) is obliquely arranged on the support block (2). The wing pieces (1) are respectively arranged on two side surfaces of the lower end of the movable rod (6). The upper end of the movable rod (6) is provided with a bending head, and the end surface of the bending head is a plane. A stop block (5) is fixed on the flat plate, and the distance between the lower end of the bending head and the upper plane of the stop block (5) is 10-30 mm. Extension arms (9) are connected with two sides of the flat plate (7) through screws (8), and the extension arms (9) extend leftwards. A slide block (12) is mounted at the left end of the extension arm (9). The structure of the vertical sliding track mechanism is described again: the fixing mechanism is planted on the ground, a vertical track (11) is arranged in the fixing mechanism, a gap is reserved between the track (11) and a sliding block (12) at the left end of an extension arm (9), and the sliding block (12) slides up and down in the track (11) and drives the extension arm (9) and a braking mechanism to move up and down. On the right side of the vertical sliding rail mechanism, there is a flange (10) facing the movable lever (6) in the brake mechanism. When a traction rope is broken, the construction operation box falls rapidly, due to the air damping effect of the fins (1) on the two side faces of the lower end of the movable rod (6), the movable rod (6) overcomes the tension of the tension spring (3), the movable rod (6) rotates clockwise around the shaft pin (4), the lower plane of the bending head at the upper end of the movable rod (6) abuts against the upper plane of the stop block (5) on the flat plate, the lower end head of the movable rod (6) is clamped on the flange (10), the whole construction operation box is hung on the vertical sliding track mechanism and cannot fall down, and therefore accidents of personal casualties and equipment damage are avoided.
