The attached lifting scaffold 100 according to the present invention is described below with reference to the drawings, and the attached lifting scaffold 100 has a reasonable structure, stability, reliability and good safety.

Referring to fig. 1 to 4, the attached lifting scaffold 100 of the present invention includes a frame body portion and a lifting rail portion 3, wherein the frame body portion is in a rectangular parallelepiped frame shape and is composed of a plurality of vertical supporting members and a plurality of horizontal supporting members, the plurality of vertical supporting members include an inner main vertical rod 1 and an auxiliary vertical rod 2, and the lifting rail portion 3 is fixedly connected to the frame body portion through the inner main vertical rod 1. As shown in fig. 1 and 2, the inner main upright 1 is a vertical support member having both ends connected to the lifting rail portions 3, and the auxiliary upright 2 is a vertical support member located at the middle of the attached lifting scaffold 100.

The vertical supporting member who has discovery lift scaffold when using of current inserted lift scaffold takes place the condition of bending deformation because of intensity is not enough, influences lift scaffold's work efficiency greatly to there is certain safe risk. In view of this, the inventor of the present invention finds through continuous thinking that the vertical supporting member of the circular tube is changed into the vertical supporting member of the square tube, so as to enhance the bearing capacity of the vertical supporting member under the condition of ensuring the cost. And for the convenience of production and installation, the existing vertical supporting members are made of materials with the same specification without considering the stress condition of the main and auxiliary frames, and because the load required to be borne by the inner main upright rod 1 is larger than the load borne by the auxiliary main upright rod 2, the vertical supporting members are easy to bend and deform, and certain safety risk exists. In order to ensure necessary safety strength and reduce cost as much as possible, the auxiliary main upright stanchion and the inner main upright stanchion need to be designed differently, i.e. the cross-sectional area of the inner main upright stanchion 1 is set to be larger than that of the auxiliary main upright stanchion 2, so that the structure of the attached lifting scaffold 100 is more reasonable, stable and reliable, and the safety performance is better.

Therefore, the inner main vertical rods 1 and the auxiliary vertical rods 2 of the attached lifting scaffold 100 of the present invention are square tubes, and as shown in fig. 3, each inner main vertical rod 1 is formed by alternatively splicing a plurality of inner main vertical rod branch tubes 11 and a plurality of inner main vertical rod tube joints 12, and both ends of each inner main vertical rod tube joint 12 are respectively embedded in the tube cavities of two adjacent inner main vertical rod branch tubes 11; similarly, each auxiliary vertical rod 2 is formed by alternatively splicing a plurality of auxiliary vertical rod branched pipes 21 and a plurality of auxiliary vertical rod pipe joints 22 (not shown in the figure), and two ends of each auxiliary vertical rod pipe joint 22 are respectively nested in the pipe cavities of two adjacent auxiliary vertical rod branched pipes 21. And, because the larger the cross sectional area, the better the bearing capacity, so set up the cross sectional area of the interior main pole setting 1 and be greater than the cross sectional area of the vice pole setting 2.

Alternatively, the cross-sectional length L1 of the inner main upright 1 may be set greater than the cross-sectional length L2 of the auxiliary upright 2, and the cross-sectional lengths L1, L2, the cross-sectional width W1 of the inner main upright 1 and the cross-sectional width W2 of the auxiliary upright 2 are each greater than or equal to 50 mm. In this way, a sufficient load-bearing capacity of the attached lifting scaffold 100 can be ensured.
