[0002] The construction hoist is a kind of commonly used construction machinery, which can efficiently transport construction materials, machines and working personnel in high-rise and super high-rise building construction. In the construction hoist, the standard section used for climbing track is all made of seamless pipe as the main chord, and the angle steel is welded into a frame structure, and then the frame structure is welded into a standard. The standard section is an important component for ensuring the stable and safe operation of the construction hoist. A good standard section can not only improve the stability of the construction hoist, but also improve the safety performance and working efficiency of the whole machine. In the construction site, a lifting frame is formed by the continuous stacking of multiple standard sections, and the construction hoist moves up and down along the lifting frame.

In the utility model, the support column is arranged between the horizontal beams through the support mechanism, which improves the support stability and prolongs the service life of the device. In addition, the support mechanism is easy to disassemble, which reduces the weight of the horizontal beam and facilitates subsequent transportation. The installation and disassembly are convenient, which ensures the installation efficiency. The positioning block, the positioning sleeve, the positioning groove and the positioning block are arranged to realize the positioning butt joint between the two section frame main bodies and the two racks, which is more accurate and improves the connection safety and stability.

[0052] Example two

[0053] According to the basis of example one increases the auxiliary function.

[0054] Referring to Figures 1-5 , the slider 23 is dovetail, the slide groove 231 and the slider 23 shape is adapted. The column 11 and the bolt 14 is provided with shielding assembly 3, the shielding assembly 3 includes: the movable groove 31, symmetrically set in the outer wall of the column 11; movable block 32, slidingly connected in the movable groove 31; top plate 33, fixedly connected to the movable block 32 one end, the top plate 33 is located above the bolt 14; support plate 34, fixedly connected to the top plate 33 bottom. The top plate 33 and the support plate 34 width is greater than the bolt 14.

[0055] When the rack one 24 and the rack two 25 move, the slider 23 at the rear side slides in the sliding groove 231, the dovetail-shaped slider 23 makes the slider 23 unable to be separated from the inside of the sliding groove 231 when the slider 23 slides in the sliding groove 231, thereby avoiding affecting the linkage effect of the rack one 24 and the rack two 25 and the gear 22.

After the connection of the bolt 14 is completed, the shielding assembly 3 shields the bolt 14, thereby avoiding rain and foreign matters from entering the groove of the bolt 14 and affecting the subsequent disassembly. After the operator installs the bolt 14, the top plate 33 is manually slid to the lower side until the bottom end of the support plate 34 contacts the top of the lower cross beam 12. At this time, the top plate 33 and the support plate 34 shield the upper side of the bolt 14, thereby reducing the probability of rain or foreign matters falling into the groove of the bolt 14 and avoiding affecting the disassembly of the operator. The width of the top plate 33 and the support plate 34 is greater than that of the bolt 14, thereby increasing the area of the combined shielding of the top plate 33 and the support plate 34, and thereby reducing the probability of rain or dust falling into the top end of the bolt 14 again.
