Description

Scaffold frame liftable prevents weighing down safety device

Technical Field

The invention relates to the field of construction safety guarantee equipment, in particular to a lifting anti-falling safety device for a scaffold.

Background

The existing scaffold operating personnel are arranged and dismantled on a scaffold body (the scaffold body refers to the whole scaffold body of the scaffold, and comprises a scaffold foundation and a scaffold body which is formed by erecting rod pieces such as vertical rods, longitudinal rods, transverse rods and cross braces and the like, and the like), and because the operating personnel are always positioned at the topmost end of the scaffold, a safety belt is hung everywhere. The safety belt is hung on a vertical rod or a vertical and horizontal rod under the feet of an operator in the prior art, the method is inconvenient for hanging and taking the safety belt, the operator cannot walk on a frame body conveniently, a new potential safety hazard is formed under the feet of the operator, and in addition, the method also does not accord with the national use principle of high hanging and low using in the safety belt use regulations. Meanwhile, because the safety belt is hung at a low position, when the safety belt falls carelessly in the operation process of personnel, the height difference of at least more than two meters exists, even if the safety belt can pull the personnel, all the periphery of the operation is various frame body pipe fittings due to falling from a high position, and casualty accidents are easily caused. Due to the reasons, under most conditions, the existing operators do not hang safety belts or only carry the safety belts on their backs to risk the operation, so that the safety hazards are greatly brought to the life safety of the operators, and the safety risks are also greatly brought to the safety management work of enterprises.

Examples

This embodiment discloses a scaffold frame liftable prevents weighing down safety device, the device includes: wire rope 1 and spacing buckle 2, wire rope 1 installs on the pole setting 3 at scaffold frame both ends, and wire rope 1 passes through the connecting piece to be connected with pole setting 3, is provided with spacing buckle 2 below wire rope 1 and 3 junctions of pole setting, prevents that wire rope 1 from gliding, and constructor's safety belt hangs on wire rope 1. Spacing buckle 2 fixed joint is on pole setting 3, and wire rope 1 is spacing by spacing buckle 2, avoids wire rope 1 gliding to appear, reduces the condition of wire rope 1 height. The diameter of the steel wire rope is selected autonomously according to actual use requirements, and the construction safety requirements are met.

The scaffold comprises upright rods 3, longitudinal horizontal rods 4 and small cross rods 11, wherein the upright rods 3, the longitudinal horizontal rods 4 and the small cross rods 11 are perpendicular to each other two by two and are connected through cross fasteners 12, and a plurality of upright rods 3 are uniformly connected on the longitudinal horizontal rods 4 at equal intervals. The longitudinal horizontal rod 4 is fixedly connected with a building through a scaffold wall connecting piece 5, and one end of the scaffold wall connecting piece 5 is inserted into the building and is connected with an embedded rod piece 6 in the building. The scaffold is wall spare 5 even and is played the effect of fixed scaffold, avoids the scaffold to rock, the skew position.

Two ends of a steel wire rope 1 are respectively fixed on upright posts 3 at two ends of the scaffold through connecting pieces, the connecting positions of the steel wire rope and connecting rods at two ends can be selected to be in diagonal connection or linear connection, and the middle of the steel wire rope 1 is lapped on a small cross rod 11 in the middle of the scaffold, so that the steel wire rope is prevented from bending and falling too much, and the height of the safety rope cannot be hung. The height of the steel wire rope 1 is 1500-2000 mm higher than the standing working surface of a constructor, and one end of a safety belt on the constructor is sleeved on the steel wire rope 1 and can freely move along the steel wire rope 1.

The connecting piece includes main rope 7, vice rope 8 and wire rope buckle 9, pole setting 3 that the scaffold was walked around to wire rope 1's one end becomes vice rope 8, 3 backs of pole setting and main rope 7 formation oval spaces are walked around to vice rope 8, installation wire rope lantern ring 10 in the space, pole setting 3 is entangled to wire rope lantern ring 10, 10mm spaces have between wire rope lantern ring 10 and the pole setting 3, the wire rope rebound of being convenient for, the space between wire rope lantern ring 10 and the pole setting 3 is less than the diameter of spacing buckle 2, so spacing buckle 2 can avoid the wire rope gliding, can realize wire rope freedom rebound again, the height adjustment, main rope 7 passes through wire rope buckle 9 fixed connection with vice rope 8. The connecting piece can be at pole setting 3 go up height-adjusting, along with the adjustment of scaffold frame height, changes wire rope 1's height.

The specific operation flow is as follows: erecting a single-side scaffold, aligning the farthest end to the corner upright rod 3, wherein the height is not less than 2000mm of the scaffold of the next step, and sleeving a special safety steel wire rope on the upright rod 3; the special steel wire rope 1 is adjusted to be 1500mm to 2000mm higher than the scaffold of the lower step, and is fixed at the lower part by a limit buckle 2. A small cross bar 11 is arranged in the middle of the steel wire rope 1 every 15000mm to 20000mm to prevent the steel wire rope 1 from overhung. The operator hangs the safety rope on the special steel wire rope 1 for operation. After the scaffold of the step is erected, the safety steel wire rope slides upwards along the vertical direction of the upright rod 3; when the scaffold is dismantled, the scaffold slides downwards, and the upright rods 3 on the two sides meet the requirement that the special safety steel wire rope 1 is hung at a certain height, and the scaffold is descended to the safety height of 2000 mm.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
