Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a telescopic tower crane safety passage device. Background Art

[0002] Tower cranes are essential lifting machinery for construction. During the construction process, due to a certain distance between the building and the tower crane, the tower body will rise with the increase in the height of the floor. The danger for tower crane drivers going up and down the tower crane every day increases, especially in rainy, snowy, hot and cold weather. The ladder is prone to ice and moisture. The tower crane driver is affected by many factors such as the weather and his own condition, which can easily cause safety accidents during the climbing process.

[0003] Traditional tower crane passages usually need to be designed according to the length of the passage. When in use, the passage is directly placed between the tower body and the main building. Its length cannot be adjusted, and its scope of application is relatively narrow. In addition, the stability of traditional tower crane passages is poor when in use, which poses a great safety hazard and is inconvenient for tower crane drivers to go to and from get off work. For this reason, we propose a retractable tower crane safety passage device. Utility Model Content

[0025] The tops of the second patterned steel plate 7 and the first patterned steel plate 6 are both welded with first rectangular tubes 17 at equal intervals in the horizontal direction, and the tops of the first rectangular tubes 17 are welded with second rectangular tubes 18 , which are vertically arranged between the second rectangular tubes 18 and the first rectangular tubes 17 .

[0026] It should be noted that when the utility model is used, the length of the tower crane channel can be adjusted according to the length distance of the channel. When adjusting, first remove the screws fixing the first channel steel 1 and the second channel steel 2, turn the adjusting knob 16 to rotate the threaded rod 9, and the slide plate 10 is moved away from the second channel steel 2 through the threaded connection between the threaded rod 9 and the threaded hole on the L-shaped fixing plate 8. The fixing rod 11 on the slide plate 10 is disconnected from the second mounting hole 14, and then the second channel steel 2 is pulled, and the second channel steel 2 slides out of the first channel steel 1, so that the length of the entire channel becomes longer. After adjustment, the adjusting knob 16 is rotated in the opposite direction, so that the fixing rod 11 and the connecting rod 12 on the slide plate 10 are respectively inserted into the second mounting hole 14 and the connecting hole 15 on the second channel steel 2, so that the first channel steel 1 and the second channel steel 2 are preliminarily fixed. Then, it is connected to the first mounting hole 13 by fixing screws to reinforce and fix the first channel steel 1 and the second channel steel 2 to ensure a firm connection between the first channel steel 1 and the second channel steel 2. The two first channel steels 1 and the plurality of third channel steels 4 are welded and fixed, and the two second channel steels 2 and the plurality of fourth channel steels 5 are welded and fixed.

After adjustment, rotate the adjusting knob 16 in the opposite direction, so that the fixing rod 11 and the connecting rod 12 on the slide plate 10 are respectively inserted into the second mounting hole 14 and the connecting hole 15 on the second channel steel 2, so that the first channel steel 1 and the second channel steel 2 are initially fixed, and finally connected to the first mounting hole 13 through the fixing screws, so that the first channel steel 1 and the second channel steel 2 are reinforced and fixed.

[0029] One end of the threaded rod 9 located outside the L-shaped fixed plate 8 is fixedly connected to an adjusting knob 16, the slide plate 10 is symmetrically fixedly connected to a connecting rod 12 on one side of the fixed rod 11, and the side wall of the second channel steel 2 is symmetrically provided with connecting holes 15 located outside the second mounting hole 14, and the connecting rod 12 is clamped inside the connecting hole 15.
