Abstract

The utility model discloses a multifunctional scaffold, which comprises two door-shaped frames (10) and a pedal (8). Upright posts (1) at the same side of the door-shaped frames (10) are respectively connected with transverse frames (7) in a sliding mode; the pedal (8) is connected with the transverse frames (7); the bottoms of the upright posts (1) are provided with universal wheels (4); a locking device which can prevent the transverse frames (7) from moving up and down is mounted between the transverse frames (7) and the upright posts (1); and a crossbeam (13) is connected between the two transverse frames (7). The utility model has the advantages of greatly improving the supporting strength of the transverse frames, effectively preventing the bending and deformation of the transverse frames and greatly improving the safety performance of users in operation.

Description

Multifunction scaffold

Technical field

The utility model relates to a kind of instrument that use in the engineering construction field, specifically is a kind of multifunction scaffold.

Background technology

Scaffold is a kind of instrument of ascend operations such as building site or indoor decoration, and it can be regulated at any time according to the different needs of operation height, can also carry out moving of any direction according to the universal wheel that the bottom connects simultaneously.Scaffold of the prior art generally all comprises two door-shaped frames, two crossbearers and is connected pedal on the crossbearer; Described door-shaped frame is a step shape framework, promptly is provided with some cross bars on two columns of door-shaped frame; Described crossbearer two ends slidably are connected between the same heel post of two door-shaped frames; The inboard of described crossbearer is provided with " L " shape groove of putting into for pedal; Be provided with the locking device that stops crossbearer to move up and down between the column of described crossbearer and door-shaped frame.Because above-mentioned crossbearer only adopts two ends to be connected with the column of described door-shaped frame, therefore, when the pedal on being positioned at crossbearer is subjected to bigger pressure, the middle part of crossbearer is easy under the effect of pressure to the both sides bending, cause this scaffold very unstable in the course of the work, also the phenomenon that the staff falls can occur when serious.

The utility model content

The technical problems to be solved in the utility model is, provides a kind of and can improve the crossbearer support strength greatly, prevents that effectively crossbearer from occuring bending and deformation, thereby improves the multifunction scaffold of user's job safety greatly.

In order to solve the problems of the technologies described above, the utility model provides a kind of multifunction scaffold with following structure, and it comprises two door-shaped frames and a pedal; All be connected with a crossbearer between the same heel post of described two door-shaped frames slidably; Described pedal is connected on the crossbearer; Described column bottom is equipped with universal wheel; The locking device that stops crossbearer to move up and down is installed between described crossbearer and the column; Be connected with a crossbeam between described two crossbearers.

After adopting said structure, the utlity model has following advantage: because the crossbearer in the utility model not only is connected on the column of door-shaped frame at two ends, but also between two crossbearers, connect a crossbeam, therefore, the utility model can rely on crossbeam that two crossbearers are held firmly, thereby improve the support strength of crossbearer greatly, prevent the crossbearer pressurized and to the phenomenon of both sides bending, stability when effectively having improved the utility model work, the safety when further guaranteeing user's operation.

As a kind of improvement of the present utility model, being connected can be between described crossbeam and two crossbearers removably connects, and this removably connecting can be adopted following concrete structure: described crossbeam comprises a horizontal beam and is arranged on the short pin of horizontal beam two ends perpendicular to ground; The medial surface of described two crossbearers is provided with a sleeve pipe for short pin insertion.The dismounting of user to scaffold is convenient in this improvement.

As another kind of improvement the of the present utility model, described horizontal beam can be connected the bottom surface of pedal.Horizontal beam is connected the pedal bottom not only can make the utility model dismounting more convenient, and it can also effectively avoid the user because of the assembling carelessness crossbeam to be forgotten that the phenomenon of installation takes place in disassembly process.

Specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, in this specific embodiment, the utility model multifunction scaffold comprises two door-shaped frames 10 and a pedal 8; All be connected with five cross bars 3 on two root posts 1 of described each door-shaped frame 10; The bottom of described column 1 is connected with universal wheel 4; All be connected with a crossbearer 7 between the same heel post 1 of described two door-shaped frames 10 slidably; The two ends of described crossbearer 7 are welded with a montant 11 respectively, and described montant 11 is provided with a groove 16 vertically; Described crossbearer 7 is slidingly connected by the column 1 on groove 16 and the door-shaped frame 10.

In this specific embodiment, removably be connected with a crossbeam 13 between described two crossbearers 7, what this mode of removably connecting adopted is following concrete structure: described crossbeam 13 comprises a horizontal beam 14 and is arranged on the short pin 15 of horizontal beam 14 two ends perpendicular to ground; The medial surface of described two crossbearers 7 is provided with a sleeve pipe 12 for short pin 15 insertions; Described horizontal beam 14 is connected the bottom surface of pedal 8.The end face of described crossbearer 7 is provided with " L " shape groove 5; Described pedal 8 is positioned at " L " shape groove 5, and the curved pin that connects by crossbearer 7 outsides 6 fixes it, is socketed with spring on the described curved pin 6; The middle part of described pedal 8 is provided with two through hole II 9, and picking and placeing of pedal 8 is convenient in the setting of through hole II 9; The two ends of described crossbearer 7 are equipped with a locking device that stops crossbearer to move up and down between column 1; Described locking device adopts following concrete structure: it comprises bayonet lock 17, plug housing 20, spring 18 and backing pin 19; Described plug housing 20 is connected on the crossbearer 7, and described plug housing 20 is " U " shape; Described bayonet lock 17 slidably is connected on the plug housing 20; Described backing pin 19 is connected the right-hand member of described bayonet lock 17; Described spring 18 is enclosed within on the bayonet lock 17; Described spring 18 and backing pin 19 are positioned at " U " shape frame of plug housing 20; The two ends of described spring 18 withstand between backing pin 19 and the plug housing 20; Described column 1 is provided with several through hole I 2 that inserts for bayonet lock 17.
