Description

Technical Field

[0001] The invention relates to the field of indoor escalator installation, in particular to an indoor escalator installation and disassembly suspension device. Background Art

[0002] Hoisting refers to the general term for the installation and positioning of equipment by a crane or a lifting mechanism. During the inspection or maintenance process, various lifting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position. When hoisting, in order to prevent the hoisted objects from falling and causing danger, a suspension device needs to be installed under the traction rope of the lifting device. Indoor escalators are generally composed of multiple groups of assembleable steps, driving parts and frame parts. The frame part is generally composed of multiple rectangular rods, the middle section of which is rectangular, and the two ends are curved. When hoisting the frame, the existing hoisting equipment generally cannot adjust the clamping position, so it can only clamp the rectangular frame in the middle section. When clamping the curved frame, if it is not maintained stable with the help of other auxiliary tools, it is easy to fall off during suspension, causing risks. For this reason, we propose an indoor escalator installation and disassembly suspension device. Summary of the invention

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides an indoor escalator installation and disassembly suspension device, which has the following beneficial effects:

[0017] 1. The indoor escalator installation and disassembly suspension device, when the indoor escalator needs to be hoisted, the skeleton of the indoor escalator is composed of a plurality of rectangular rods, the middle section of which is rectangular, and the two ends are curved. When hoisting the middle part or the curved shape, the lifting device moves the rectangular plate to the top of the middle section or the curved shape, and then the driving component is started to drive the telescopic device to telescope, and then the lifting device drives the rectangular plate to descend. At this time, the vertical rod will be located on both sides of the middle end or the curved shape, and then the driving component is started to make the longitudinal rods on both sides move toward the side close to each other. When hoisting the middle section, the vertical rod is started, and the vertical rods on both sides are moved to the same height for clamping. When hoisting the curved section, because the curved section is hoisted in an arc shape, the vertical rods on both sides can move to different heights respectively, and adaptive clamping is performed according to the bending position and height of the curved section, and then hoisting is performed. The device can adaptively hoist the two ends of the arc and the middle rectangular section of the indoor escalator, and can be hoisted without replacement, which is convenient to use.

[0018] 2. The indoor escalator is installed and disassembled by the suspension device. When the motor 2 is started, it drives the gear 2 to rotate, and then drives the gear 1 to rotate, and then drives the connecting rod to rotate, and then drives the circular cross bar to rotate. With the action of the thread, the circular cross bar moves laterally inside the rectangular plate, thereby driving the longitudinal bars on both sides to extend outward. This arrangement can hoist indoor escalator frames of different widths, and is very practical.

[0019] 3. The indoor escalator installation and disassembly suspension device, when clamping the indoor escalator, since the frame length of each indoor escalator is different, in order to maintain the stability of clamping and hoisting, the clamping spacing on the same side is also different. Once the motor is started, it drives the screw to rotate. Due to the problem of the thread direction on both sides, the moving blocks on both sides are displaced in different directions, thereby changing the spacing between the two vertical rods. This setting can adaptively adjust the clamping spacing according to the frame length of the indoor escalator to be hoisted, and has good adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

When the walking frame 13 needs to move up and down, the telescopic cylinder 14 is started, and its output shaft is contracted, and then the tooth 17 is no longer engaged with the tooth 1 7. When the walking frame 13 is adjusted up and down and needs to be fixed, the telescopic cylinder 14 is started, and its output shaft extends to the side close to the tooth 1 7, and then the tooth 17 is engaged with the tooth 1 7 to complete the fixation.

[0039] The clamping structure includes an L-shaped plate 16, a pressing plate 18 and a bolt 19.

Subsequently, the tooth 2 17 is no longer engaged with the tooth 1 7, and the motor 3 28 is started, driving the gear 4 29 to rotate, and cooperates with the meshing on the vertical rod 6 to move up and down. When the up and down positions of the walking frame 13 are adjusted and need to be fixed, the telescopic cylinder 14 is started, and its output shaft extends to the side close to the tooth 1 7, and then the tooth 2 17 is engaged with the tooth 1 7 to complete the fixation. Subsequently, according to the position of the hoisted skeleton, observe whether it is in the bending section. If so, rotate the L-shaped plate 16 to keep the L-shaped plate 16 corresponding to the bending section, and then fit the bending part of the L-shaped plate 16 onto the indoor escalator skeleton, and then rotate the bolt 19 so that the pressing plate 18 is pressed onto the indoor escalator skeleton, so as to realize the pressing and clamping of the indoor escalator skeleton, and then the lifting equipment lifts the connecting beam 2 to drive the indoor escalator to be suspended.
