Abstract

The utility model provides a combined ascending ladder which has simple structure and convenient use and move and is suitable for multipoint aloft work. Two side ladder frames (2) are respectively inserted into two bottom frames (1), the side ladder frames (2) are respectively connected with two upper frames (3), a horizontal operating platform (6) is positioned across upper ladder beams of the two side ladder frames (2), and a side beam rod of one bottom frame (1) is provided with a floating caster wheel (5). In operation, the components are mutually inserted and combined to form a ladder in a definite height; after the bottom edge of the caster wheel is landed, the whole ladder frame can move along each operating points to and fro; a metal pipe component can be detached to be arranged in a special portable bag or box, when the ladder is not used.

Description

The combined type ladder of ascending a height

Affiliated technical field

The utility model belongs to building auxiliary equipment field, relates generally 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.

Background technology

Ladder is a kind of tradition and the instrument of ascending a height commonly used, the ladder of being used always in daily life and work mainly contains a word vertical ladder so far, double ladder and lift etc., their structure is mostly relatively heavier, it is convenient inadequately to move, in the multiple spot operation, be unfavorable for increasing work efficiency, in recent years, as to the improvement of above-mentioned prior art structure with replenish, also once the someone develops the device of some folding ladder classes, but owing to will be furnished with class such as hinged toward contact in this series products, pin, many members such as sleeve pipe, cause the complex structure of its device, involve great expense, have influence on the functional performance of himself to a certain extent.

Summary of the invention

The purpose of this utility model is to overcome the defective of above prior art, and then a kind of simple in structure, use and conveniently moving is provided and is suitable for the combined type working stand of multiple spot ascend operation.

In order to realize the foregoing invention purpose, the ladder of ascending a height provided by the utility model is a kind of firm ladder of being pegged graft mutually and being constituted by how secondary metal tube member, be in two pairs on the analog-U shaped underframe of horizontally set, be respectively equipped with two secondary its lower ends and can be inserted in the side ladder that is vertical setting on the underframe curb girder, what be provided with in the upper end of two secondary side ladders that two pairs can be inserted in side ladder upper end is the analog-U shaped upper frame of falling of horizontally set, during use, above-mentioned all members are pegged graft mutually, the combined bay that forms just constitutes a ladder with certain altitude, on the beam column of the front side of two secondary underframe, also respectively be provided with a castor, when working stand during by static storing, relatively face is unsettled for the following root edge of lid castor, in the time of need carrying out the multiple spot ascend operation, ladder can be lifted slightly away from a side of castor, even the root edge of castor lands, and ladder is moved along the stand, operating point by means of this, time spent not at ordinary times, each metal tube member on the ladder can be pulled down, tie or directly put in the special-purpose bag (case) with rope, make things convenient for the user to carry.

Compared with prior art, of the present utility model simple and reasonable, use easy to assemblyly, leave standstill firm safety, convenient flexibly when mobile, can alleviate staff's labour intensity dramatically, increase work efficiency, and make work that continuity preferably be arranged.

Description of drawings

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 metal tube member grafting form schematic diagram.

The specific embodiment

As shown in Figure 2, analog-U shaped underframe (1) curves the metal tube with bottom girder and curb girder by a velamen and constitutes, respectively be provided with a runners (4) in the both sides of bottom girder, the bottom surface of runners (4) is lower than the root edge that is located at the castor (5) on underframe (1) the curb girder bar slightly, be provided with one in the top system of underframe curb girder and be crack mouthful of trumpet-shaped bell and spigot, have one section oblique receipts formula intubate as shown in Figure 3 in the lower end of side ladder (2) pipe; Equally, the upper end of side ladder (2) with fall the curb girder lower end of analog-U shaped upper frame (3) and make respectively and be provided with bell and spigot and intubate identical with aforementioned shapes and that can peg graft mutually, have some grades of terraced beams on the side ladder (2), also can between the last terraced beam of both sides ladder (2), set up a horizontal table (6) as shown in Figure 1 in concrete the enforcement, 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 working stand stability on underframe (1) and the side ladder (2).

Claims

1, a kind of combined type ladder of ascending a height, be in two pairs on the analog-U shaped underframe of horizontally set, be respectively equipped with two pairs and be the side ladder of vertical setting, be provided with two pairs in the upper end of two secondary side ladders and be the analog-U shaped upper frame of falling of horizontally set, it is characterized in that: the bottom girder both sides of analog-U shaped underframe (1) respectively are provided with a runners (4), also respectively are provided with a castor (5) on the preceding beam column of underframe (1).

2, the combined type according to claim 1 ladder of ascending a height is characterized in that: be provided with a secondary horizontal table (6) between the last terraced beam of two side ladders (2).
