Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable movable assembly platform for steel roof trusses. Background Art

[0002] The adjustable mobile assembly platform for steel roof trusses plays an important role in steel structure construction. It can not only improve construction efficiency and safety, but also simplify the construction process, adapt to various construction environments, improve construction quality and reduce construction costs.

[0003] Although today's technology has many advantages, its disadvantage is that many existing lifting platforms rely on emergency braking systems to prevent the platform from falling. Emergency braking systems usually require power support. If there is a problem with the motor or power supply, the sensor may not work properly, causing the braking system to be unable to correctly identify the position or speed of the platform, and thus unable to initiate braking in time, causing the platform to fall due to loss of upward driving force, endangering the health of personnel and reducing the service life of the equipment. At the same time, existing emergency braking systems are usually more complex, involving electronic control units, sensors and other components. Complex systems often mean higher costs and maintenance difficulties. Utility Model Content

A ladder 18 is fixedly connected to the outer surface of the work platform 1, and a fixed block 19 is fixedly connected to the bottom of the multiple support seats 3. The outer surfaces of the multiple fixed blocks 19 are provided with universal wheels 20. The inner surfaces of the multiple slots 11 are provided with braking mechanisms to avoid the problem of the platform falling due to loss of driving force during ascent, which ensures the health of the staff to a certain extent and improves the service life of the equipment to a certain extent. The structure of the spring 16 and the card plate 14 is simple, which reduces the maintenance cost and difficulty compared with the use of sensors and electronic components, and is easy to use.

[0019] like Figure 4As shown, the braking mechanism includes multiple operating rods 12, and the multiple operating rods 12 are movably embedded in the inner surfaces of multiple slots 11. The multiple operating rods 12 are evenly divided into two groups. The outer surfaces of the two groups of operating rods 12 are fixedly connected with pull handles 13, and the outer surfaces of the multiple operating rods 12 are fixedly connected with clamping plates 14. The inner surfaces of the multiple clamping plates 14 are fixedly installed with rotating shaft 2 15, and the outer surfaces of the multiple rotating shaft 2 15 are fixedly installed with two springs 16. The outer surfaces of the multiple springs 16 are fixedly connected to positioning columns 17. The slots 11 can limit the moving trajectory of the operating rods 12, thereby avoiding derailment of the operating rods 12 and affecting the use of the equipment.

[0020] like Figure 1 and Figure 2 As shown, two rotating shafts 6 are movably embedded in the inner surfaces of multiple positioning plates 4, and one rotating shaft 6 is fixedly installed on the outer surface of the output shaft of the motor 10. The rotating shaft 6 can transmit the power of the motor 10 to the gear 5 to make the gear 5 rotate.

[0021] like Figure 4 As shown, multiple rotating shafts 15 are movably embedded in the inner surfaces of multiple support seats 3, and multiple positioning columns 17 are fixedly connected to the inner surfaces of multiple support seats 3.

[0022] Working principle: This equipment is an adjustable mobile assembly platform for steel roof trusses. When in use, first use the universal wheel 20 on the fixed block 19 to move the platform to the work site, and the universal wheel 20 has a locking function to prevent the universal wheel 20 from continuing to rotate, and then start the motor 10 on the support plate 9. The motor 10 drives one of the rotating shafts 6 to rotate through the output shaft. One of the rotating shafts 6 rotates synchronously with the cooperation of the pulley 7 and the transmission belt 8, and then the two rotating shafts 6 rotate on the inner surface of the positioning plate 4. The two rotating shafts 6 drive the multiple tooth plates 2 to extend out of the multiple support seats 3 through the multiple gears 5. As the multiple tooth plates 2 are extended and retracted, the horizontal height of the working platform 1 is increased. The operator uses the ladder 18 to reach the working platform 1 to work. At the same time, every time the tooth plate 2 extends a tooth, When the tooth plate 2 is extended, when the card plate 14 is no longer in contact with the tooth plate 2, the spring 16 releases the elastic potential energy, causing the card plate 14 to move to its initial position, and then continue to be stuck on the tooth plate 2, limiting the tooth plate 2 from moving downward, and the pull handle 13 can manually apply external force to the operating rod 12, so that the card plate 14 does not contact the tooth plate 2, thereby preventing the working platform 1 from falling suddenly when rising, ensuring the health of the staff and improving the service life of the equipment.
