Abstract

The utility model relates to a tall building out-of-window operation safety scaffold which comprises a straight ladder. The utility model is characterized in that the upper end of the straight ladder is connected with a trapeziform cross beam through a pin shaft, the inner surface of the upper part of the straight ladder is fixedly provided with an upper and a lower supporting feet with an identical height, and a group of adjustable clamping supporting feet is connected under the cross beam on one side near the direction of the supporting feet on positions where intervals are bigger than the thickness of a wall body. The adjustable clamping supporting feet are respectively, downwards, vertically and fixedly provided with a steel pipe on both sides of the cross beam. The lower part of the steel pipe is screwed with a threaded rod which is formed by that a rotary handle is installed on the outer end of the threaded rod and a pressure block is installed on the inner end of the threaded rod. The tall building out-of-window operation safety scaffold of the utility model can be adjusted and assembled according to the needs of the thickness of the wall body and working positions. Workers can stand in a guard rail for carrying out work and can also stand on the straight ladder for carrying out the work. Because the ladder and the cross beam are hinged by the pin shaft, the adjustable clamping supporting feet, a pedal and the guard rail are only required to be disassembled for folding the tall building out-of-window operation safety scaffold into a triangular ladder or a long ladder. The tall building out-of-window operation safety scaffold has the advantages of convenient and safe use and multiple purposes and performance.

Description

High building is the job safety frame outside window

Technical field:

The utility model relates to power tool, and the high building that particularly a kind of suitable workman fits up in the wall outer side of high-rise building is the job safety frame outside window.

Background technology:

At present, when operations such as outdoor advertising, air-conditioning, rain sunshade are installed on high building, adopt ties up to rope on workman's waist or on the safety belt more, the rope other end is hauled in window by the companion, the workman passes in and out in window, climbs up and climbs down, and does not have the foothold that is fit to, fitment operation is got up both inconvenient, dangerous again.

Summary of the invention:

The purpose of this utility model is the defective that exists at high building operation outside window, and it is convenient to design a kind of both operations, can guarantee safe high building job safety frame outside window again effectively.

The technical solution of the utility model is finished as follows, it includes a vertical ladder, it is characterized in that, the vertical ladder upper end is connected on the trapezoidal crossbeam by bearing pin, the contour lower support leg that is fixed with in the inside, vertical ladder top, below crossbeam, be connected with one group of adjustable clamping leg greater than the position of thickness of wall body at interval by leg direction one side, adjustable clamping leg is to fix a steel pipe respectively downward vertically in the crossbeam both sides, a screw rod is spirally connected in the steel pipe bottom, rotary handle is installed in the screw rod outer end, and the screw rod inner end is installed briquetting and formed.The certain distance that also crossbeam can be stretched out is equipped with dismountable pedal on the crossbeam extension, in the periphery of crossbeam extension dismountable protective guard is set.Roll-over protective structure of the present utility model can be adjusted and assemble according to thickness of wall body and job position needs, and the workman may stand in and carries out operation in the protective guard, also may stand in and carries out operation on the vertical ladder.Hinged because of ladder and crossbeam with bearing pin, as long as adjustable clamping leg and pedal and protective guard are removed, it can be folded into triangle ladder or a long ladder.The utlity model has advantage easy to use, safe and the multipurpose energy.

Description of drawings:

Fig. 1 is a basic structure schematic diagram of the present utility model; Fig. 2 is the left view of Fig. 1; Fig. 3 installs a kind of structural representation on the wall when extending crossbeam for the utility model band; The structural representation of Fig. 4 when making long vertical ladder; Fig. 5 is as the triangle structural representation in when ladder.Among the figure, 1. trapezoidal crossbeam, 2. rotary handle, 3. adjustable clamping leg, 4. leg, 5. vertical ladder, 6. diagonal brace, 7. bearing pin, 8. protective guard, 9. pedal, 10. screw.

The specific embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing, high building of the present utility model is the job safety frame outside window, it includes a vertical ladder 5, the vertical ladder upper end is connected on the trapezoidal crossbeam 1 by bearing pin 7, the contour secured in parallel in the inside, vertical ladder top has two groups of legs 4 up and down, is connected with one group of adjustable clamping leg 3 greater than the position of thickness of wall body at interval by leg direction one side below trapezoidal crossbeam.Adjustable clamping leg is to fix a steel pipe respectively downward vertically in the crossbeam both sides, the screw rod that is spirally connected in the steel pipe bottom, and rotary handle 2 is installed in the screw rod outer end, and the screw rod inner end is installed briquetting and is formed.Certain distance also can stretch out above-mentioned trapezoidal crossbeam, the pedal of dismantling by screw 10 9 is installed on the crossbeam extension, and install protective guard 8 by securing member in the periphery of crossbeam extension, for more stable, both sides are used a diagonal brace of bolt (as shown in Figure 3) respectively in the middle part of extending on both sides, crossbeam outer end and the vertical ladder.Roll-over protective structure of the present utility model can be adjusted and assemble according to thickness of wall body and job position needs, and the workman may stand in and carries out operation in the protective guard 8, also may stand in and carries out operation on the vertical ladder 5.Hinged because of vertical ladder and trapezoidal crossbeam with bearing pin, as long as adjustable clamping leg and pedal and protective guard are removed, it can be folded into a triangle ladder (as shown in Figure 5) or a long ladder (as shown in Figure 4), make it to have multi-functional advantage.
