Abstract

The utility model relates to a working ladder which is composed of two similar U-shaped bottom frames arranged horizontally, two side ladder frames arranged vertically and two reverse similar U-shaped top frames, which are all made of metal tubes and connected with each other. Two sides of the bottom beams of the similar U-shaped bottom frames are respectively provided with a foot seat. The front side beam columns of the two bottom frames are respectively provided with a hung caster wheel. In the process of working, the metal components are connected and combined to form the ladder provided with certain height. When the bottom edge of the caster wheel touches the ground, the whole ladder can be pushed and pulled to move along each operation point. When the ladder is not used, the components can be detached and put into a special portable bag.

Description

The combined type working stand that can conveniently move

The utility model content belongs to building auxiliary equipment field, relates to a kind of follow-on combined ladder, and its product is suitable for not having the ascend operation of other supporter in certain altitude.

Ladder is a kind of tradition and the apparatus of ascending a height commonly used.People's ladder of being used always in daily life and work mainly contains a word vertical ladder, double ladder and lift etc. so far, they all exist defectives such as relatively heavier, the mobile underaction convenience of structure, are unfavorable for increasing work efficiency in the multiple spot construction operation.In recent years, as to the improvement of above-mentioned known technology structure with replenish, also once there was people's Development and design to go out the device of some folding ladder classes, but build many members owing to be furnished with class such as hinge, pin, sleeve pipe etc. toward contact in this series products, cause complex structure, the cost of its device relatively expensive, have influence on the functional performance of himself to a certain extent.

The purpose of this utility model is to overcome the existing in prior technology defective, and then a kind of simple and reasonable, easy-to-use, combined type working stand that can conveniently move of being suitable for working site multiple spot ascend operation is provided.

Be used to realize that the technical solution of foregoing invention purpose is such: this combined type working stand is pegged graft mutually by the analog-U shaped upper frame of falling of horizontally set by the side ladder of vertical setting and two pairs by the analog-U shaped underframe of horizontally set, two pairs by two pairs of all making with metal tube and is constituted, respectively be provided with a runners in the bottom girder both sides of analog-U shaped underframe, on the beam column of the front side of two secondary underframe, respectively be provided with a castor, when the static placement of working stand, the relative ground of the root edge of castor is unsettled.During use, above-described all members are pegged graft mutually, and castor is contained on the beam column of front side, formed Combined shelf body has just constituted a ladder with certain altitude.When needs carry out the multiple spot ascend operation, ladder can be lifted slightly away from a side of castor, cause the root edge of castor to land, and can whereby whole ladder be moved along each operating point push-and-pull.After hours, each metal tube member on this combined ladder frame can be pulled down, tie up or directly put into special-purpose bag (case), make things convenient for the user to go out to carry with rope band.

Compared with prior art, device described in the utility model simple and reasonable, use easy to assembly, leave standstill in firm safety, convenient flexibly when mobile, can alleviate labor intensity of operating personnel dramatically, increase work efficiency, and making operation that continuity preferably be arranged, this product can be widely used in multiple ascend operations such as building, installation, telecommunications, the large-scale calligraphy and painting advertisement of making.

Below with reference to accompanying drawing the utility model content is described further.

Fig. 1 is the structural representation of a specific embodiment of the utility model.

Fig. 2 is the package assembly schematic diagram of Fig. 1.

Fig. 3 is a metal tube member grafting form schematic diagram.

As shown in the figure, the combined type working stand that can conveniently move described in the utility model is made up of analog-U shaped underframe 1, side ladder 2, the members such as analog-U shaped upper frame 3, castor 5 that fall.Analog-U shaped underframe 1 is bent into the metal tube with bottom girder and curb girder by a velamen and constitutes, and castor 5 is located at the bottom of underframe 1 front side beam column, respectively is provided with a runners 4 in the both sides of bottom girder, and the bottom surface of runners 4 is lower than the root edge that is located at castor 5 on the underframe 1 front side beam column slightly.To be a pair make of metal tube side ladder 2 has the member of some grades of terraced beams on it.3 of upper frames are one and bend the inverted U member that forms with metal tube.Have one on the top of underframe 1 curb girder and be crack mouthful of trumpet-shaped bell and spigot, have one section oblique receipts formula intubate in the lower end of side ladder 2; Equally, make respectively in the curb girder lower end of the upper end of side ladder 2 pipes and upper frame 3 and be provided with bell and spigot and intubate identical with aforementioned shapes and that can peg graft mutually.Each tubular metal member can be assembled into complete working stand by socket on above-mentioned all members and intubate.Can be in concrete the enforcement having set up a secondary horizontal table 6 on two side ladders 2 between the terraced beam, to make things convenient for user activity or place tool etc. thereon.Number in the figure 7 is for being connected the reinforcing rib that is used to strengthen the working stand resistance to overturning on underframe 1 and the side ladder.

Claims

1, a kind of combined type working stand that can conveniently move, it is characterized in that this ladder is made of analog-U shaped underframe (1), two secondary the pegging graft mutually by the analog-U shaped upper frame of falling of horizontally set (3) by side ladder (2) that vertically is provided with and two pairs of two pairs of all making with metal tube by horizontally set, respectively be provided with a runners (4) in the bottom girder both sides of analog-U shaped underframe (1), on the front side beam column of two secondary underframe (1), respectively be provided with a castor (5), when the static placement of working stand, the relative ground of root edge of castor (5) is unsettled.

2, the combined type working stand that can conveniently move according to claim 1, it is characterized in that having one on the top of underframe (1) curb girder is crack mouthful of trumpet-shaped bell and spigot, the lower end of side ladder (2) has one section oblique receipts formula intubate, makes respectively in the upper end and the curb girder lower end of upper frame (3) of side ladder (2) pipe and is provided with bell and spigot and intubate identical with aforementioned shapes and that can peg graft mutually.

3, according to claim 1, the 2 described combined type working stands that can conveniently move, it is characterized in that between the last terraced beam of two side ladders (2), having set up a secondary horizontal table (6).
