Abstract

The utility model provides a swing needle type fall preventing device for a scaffold, and belongs to an anti-fall protecting device which is suitable for adhering to a lifting scaffold. The swing needle type fall preventing device comprises an adhering frame and a bearing frame, wherein the adhering frame comprises a basic component (1) connected with a building structure, a pull rod (3) fixedly connected with the basic component, and a supporting rod (2); the bearing frame (5) is installed at the position of the joint of the pull rod and the supporting rod, is provided with a guide groove which is matched with a guide rail (4) adhered to a lifting scaffold frame body; the swing needle type fall preventing device is arranged on the bearing frame; the rear end of a swing needle (6) is installed on the bearing frame through a hinge pin (8); the bottom part of the middle section of the swing needle is arranged on a cross section of the bearing frame; the bottom part of the front end of the swing needle is arch-shaped; a cross shaft of the guide rail laps over the front end of the swing needle; and when the guide rail moves downwards, the swing needle cannot swing downwards, so that the cross shaft of the guide rail is blocked, and the guide rail cannot move downwards continuously. The swing needle type fall preventing device has the characteristics of adopting a compact structure, having simple principle, and being safe and reliable.

Description

Balancing point type scaffold catching device

Technical field

The utility model relates to a kind of fixture of construction implement, particularly belongs to a kind of fall protection equipment that is applicable to attached lift scaffold.

Background technology

Attached lift scaffold, as a kind of advanced auxiliary construction technology high-rise, construction of super highrise building, the application on the building site is more and more universal.Compare with traditional overhanging scaffold, it has, and the material of taking is few, and labor intensive is few, does not influence the engineering construction progress, the advantage of outstanding building site image.But, because its application time is shorter, product is still perfect not to the utmost, and there is safety defect in various degree in design in the product of using at present, and security incident happens occasionally, wherein Zui Da potential safety hazard is the support body problem of falling, though taked many fall arrest measures, many fall arrest utensils have been used, because design is unreasonable, or, be easy to generate misoperation because of complex structure; Or because of delay of response, malfunctioning, failure phenomenon takes place repeatedly, therefore, the potential safety hazard of attached lift scaffold support body accidental falling does not still obtain eradicating.

Summary of the invention

The purpose of this utility model promptly is to provide a kind of novel balancing point type scaffold catching device, to reach reasonable in design, simple in structure, safe and reliable purpose.

Balancing point type scaffold catching device disclosed in the utility model comprises attaching frame and bearing support; Attaching frame comprise the basic part that connects with building structure, with the pull bar and the strut of basic part fixed connection; Bearing support is installed in the position of pull bar and strut combination; Bearing support has gathering sill, cooperates with the guide rail of attached lift scaffold support body; It is characterized in that the balancing point anti-drop device is set on the described bearing support, and the rear end of balancing point is installed on the bearing support by bearing pin, bottom, stage casing load is on the crossbeam of bearing support, and front bottom end is curved.

Balancing point type scaffold catching device provided by the utility model, when guide rail moved upward, the guide rail transverse axis slipped over the arcwall face of balancing point front bottom end, balancing point was lifted and upwards swing, and is without hindrance to guide rail; On the contrary, when guide rail moves downward, can not guide rail transverse axis load be lived to lower swing, make guide rail can not continue to move down because of balancing point.As seen, the utlity model has compact conformation, simple, the safe and reliable characteristics of principle.

Description of drawings

Accompanying drawing partly discloses specific embodiment of the utility model, wherein,

Fig. 1, the utility model structural representation;

Fig. 2, A-A is to schematic diagram.

The specific embodiment

As shown in Figure 1 and Figure 2, attaching frame of the present utility model comprise the basic part 1 that connects with building structure, with the pull bar 3 and the strut 2 of basic part fixed connection.Attaching frame of the present utility model adopts leg-of-mutton structural shape, comprises the pull bar 3 of vertical basic part 1, level and oblique strut 2.Bearing support 5 is established in the joint portion of pull bar and strut, and gathering sill is arranged on the bearing support, cooperates with the guide rail 4 of support body.

As shown in Figure 1 and Figure 2, characteristics of the present utility model are to have balancing point type fall-preventing device, are made of balancing point 6.The rear end of balancing point is installed on the bearing support 5 by bearing pin 8, and bottom, stage casing load is on the crossbeam of bearing support, and front bottom end is curved, and under normal circumstances, because the effect of deadweight, guide rail transverse axis 7 falls to riding on the front end of balancing point.When guide rail moved upward, the guide rail transverse axis slipped over the arcwall face of balancing point front bottom end, balancing point was lifted and upwards swing, and guide rail is not produced obstruction; On the contrary, when guide rail moves downward,, thereby guide rail transverse axis load is lived, make guide rail can not continue to move down because of balancing point can not be to lower swing.

The utility model can be arranged separately on the attached lift scaffold, also can overlap aggregate erection more, according to the field condition use of arranging in pairs or groups flexibly, has simple in structure, easy accessibility, safe and reliable characteristics.
