Description

Technical Field

[0001] The invention relates to the technical field of building construction platforms, in particular to a steel structure construction platform for building construction. Background Art

[0002] A variety of construction platforms are used in the construction process, among which the most commonly used is the steel structure hanging basket. The hanging basket is a construction tool for high-altitude operations in construction projects. It is used for curtain wall installation and exterior wall cleaning. The cantilever mechanism is erected on the building or structure, and the suspension platform is driven by a lifting mechanism. The construction facility runs up and down along the facade of the building or structure through a steel wire rope.

[0003] Generally, suspended construction platforms use traditional steel wire suspension. During operation, when the hoist of the hanging basket fails or the power rope breaks, the safety lock will automatically lock the safety rope. At this time, the personnel will be suspended in the air and unable to actively escape. A small number of steel structure construction platforms with escape structures are only equipped with escape mechanisms for releasing ropes to avoid being too heavy. While this requires skills from personnel, it cannot guarantee their safe escape. Summary of the invention

[0017] When in use, the safety lock 2 connects the power rope and the safety rope hanging from the top of the building, and the hoist 3 is connected to the power rope. The hoist 3 winds and releases the power rope to control the height of the hanging basket outer frame 1. When the power rope is accidentally disconnected or the falling speed of the hanging basket outer frame 1 exceeds the safety value, the safety lock 2 automatically locks the safety rope, and the personnel moves to the central hanging basket frame 7. The personnel controls the first motor 11 to rotate through the control box 8, so that the parallel linkage plate 12 rotates, and the parallel linkage plate 12 drives the V-shaped frame 13 to move, and the V-shaped frame 13 drives the first pedal 14 to rotate toward the central hanging basket frame 7, and the V-shaped frame 13 drives the second pedal 14 to rotate toward the central hanging basket frame 7. The plate 15 moves, during which the second gear 17 rotates around the first gear 16, and the second gear 17 drives the second pedal 15 to rotate, so that the second pedal 15 rotates toward the first pedal 14, so that the first pedal 14 and the second pedal 15 jointly perform enclosure operations on the space on both sides of the central hanging basket frame 7, and then the vertical release mechanism 6 releases the central hanging basket frame 7. If the central hanging basket frame 7 falls directly to the ground, the personnel escape from the ground.

During normal transportation, the supporting structure 4, the retractable escape structure 5, and the hanging basket outer frame 1 of the present invention jointly provide high-altitude safety protection for high-altitude workers and move personnel. If the hanging basket outer frame 1 falls too fast or the power rope connected to the hoist 3 breaks, the personnel are moved to the ground or into a building through the downward moving central hanging basket frame 7 and the unfolded elastic telescopic pedal mechanism 9 to ensure the safety of the personnel. During this period, the first pedal 14 and the second pedal 15 jointly provide safety protection for the personnel, avoiding the installation of an additional baffle structure of the present invention. While limiting the increase in the weight of the present invention, the operation is simple, thereby improving the safety of the present invention.

[0018] In one case of this embodiment, the supporting structure 4 includes two sets of supporting plates 18 fixedly connected to the hanging basket outer frame 1, and the first pedal 14 and the second pedal 15 are both movably connected to the supporting plates 18, and a magnet 19 is fixedly installed in the supporting plates 18. The magnet 19 is used to magnetically attract the first pedal 14 and the second pedal 15 to prevent the first pedal 14 and the second pedal 15 from moving freely, and the supporting plate 18 supports the first pedal 14 and the second pedal 15, thereby providing support for the first pedal 14 and the second pedal 15.

[0019] In one case of the present embodiment, the vertical release mechanism 6 includes an upper frame 20 fixedly connected to the outer frame 1 of the hanging basket, the upper frame 20 is fixedly connected with two groups of power shells 21, a double-output shaft motor 22 is fixedly installed in the middle of the power shell 21, the output end of the double-output shaft motor 22 is fixedly connected with a screw rod 23, the screw rod 23 is threadedly connected with a pin block 24 slidably connected to the power shell 21, the pin block 24 is movably connected to the central hanging basket frame 7, the power shell 21 is fixedly connected with two groups of second motors 25, the output end of the second motor 25 is fixedly connected with a wire wheel 26, the wire wheel 26 is wound with a steel cable 27, and the steel cable 27 is fixedly connected to the central hanging basket frame 7. The double-output shaft motor 22 drives the screw rod 23 to rotate, and the rotating screw rod 23 drives the pin block 24 to move, so that the pin block 24 slides in the power shell 21 and disengages from the central hanging basket frame 7, and then the second motor 25 drives the wire wheel 26 to rotate, so that the wire wheel 26 releases the steel cable 27, so that the central hanging basket frame 7 falls to control the height of the central hanging basket frame 7.

[0020] In one case of the present embodiment, the elastic telescopic pedal mechanism 9 includes an outer plate 28 hinged to the central hanging basket frame 7, the outer plate 28 is slidably connected to the inner plate 29, and multiple groups of first springs are installed between the outer plate 28 and the inner plate 29. The central hanging basket frame 7 is fixedly connected to two groups of limit sleeves 30, each group of limit sleeves 30 is movably connected to a group of connecting blocks 31, and the two groups of connecting blocks 31 are slidably connected to a group of hollow beams 32 together, and a hollow cavity is opened in the hollow beam 32, and the hollow cavity is filled with hydraulic oil. A second spring is fixedly installed in the hollow beam 32, and the second spring is fixedly connected to a pressure block 33, and the pressure block 33 is movably connected to a safety pin 45. The pressure block 33 is slidably connected to the hollow beam 32, and the hollow beam 32 is fixedly connected to a hook frame 34, and the hook frame 34 is movably connected to the upper end surface of the inner plate 29. The pressing block 33 is pressed toward the hollow cavity of the hollow beam 32. At this time, the second spring is compressed, and the hydraulic oil in the hollow cavity is pushed toward the connecting block 31. At this time, under the push of the hydraulic oil on the connecting block 31, the connecting block 31 moves and disengages from the limiting sleeve 30. At this time, the hollow beam 32 is removed, so that the hook frame 34 is separated from the inner plate 29. Under the joint push of multiple groups of first springs, the inner plate 29 moves in the direction away from the outer plate 28 and pushes the outer plate 28 to rotate, so that the inner plate 29 falls on the building to provide a channel for people to escape.

[0021] In one case of this embodiment, the central hanging basket frame 7 is fixedly connected with two sets of belt release shells 35, and the belt release shells 35 are fixedly connected with coil springs, and the coil springs are connected with pulleys 37 through connecting shafts 36, and the pulleys 37 are rotatably installed in the belt release shells 35, and the pulleys 37 are connected with protective belts 38, and the protective belts 38 are fixedly connected with the inner plate 29. With the movement and rotation of the inner plate 29, the protective belt 38 is pulled to make the pulley 37 rotate and release the protective belt 38. With the complete release of the protective belt 38, on the one hand, the protective belt 38 limits the rotation angle of the inner plate 29 by pulling the inner plate 29, and on the other hand, the extended protective belt 38 provides lateral limit protection for people walking on the outer plate 28 and the inner plate 29.

[0022] In one case of this embodiment, an inner groove 39 is provided on one side of the first pedal 14 away from the support plate 18, and a handle 40 is hinged in the inner groove 39. When the first motor 11 cannot be powered on normally, a person actively pulls the handle 40 to drive the first pedal 14 to rotate.

The central hanging basket frame 7 is fixedly connected to a guide sleeve 43, and the guide sleeve 43 is slidably connected to a pin 44 adapted to the positioning hole 42, and a third spring is installed between the pin 44 and the guide sleeve 43. During the rotation of the parallel linkage plate 12, the inclined guide surface on the arc-shaped orifice plate 41 squeezes the end of the latch 44, so that the latch 44 compresses the third spring, and then under the push of the third spring, the latch 44 is inserted into the positioning hole 42 to limit the movement of the arc-shaped orifice plate 41, thereby limiting the rotation of the parallel linkage plate 12. At this time, since the first gear 16 and the second gear 17 are engaged with each other, and the V-shaped frame 13 connected to the parallel linkage plate 12 is simultaneously connected to the first pedal 14 and the second pedal 15, the first pedal 14 and the second pedal 15 are limited, so that when the first motor 11 is not powered, the first pedal 14 and the second pedal 15 are limited from rotating, so as to ensure that the first pedal 14 and the second pedal 15 provide normal enclosure protection for personnel.

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
