The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Reference Figure 1 As shown, the present invention provides a visual auxiliary steel structure hoisting device, including: a base plate 1, an image collector 2, and a display.

The light-transmitting hole 10 is aligned with the bolt hole on the bottom plate of the steel column. The substrate 1 is magnetically adsorbed to the bottom plate of the steel column through a magnetic adsorption member 11.

[0032] In this embodiment, the substrate is rectangular and there are multiple magnetic elements disposed on the substrate.

[0033] As a preferred embodiment, the magnetic attraction member 11 is a magnet sheet.

[0034] In this embodiment, the substrate 1 is bonded to a plurality of magnetic elements 11. The plurality of magnetic elements 11 are arranged at intervals along the circumferential direction of the substrate 1.

[0035] The number of magnetic attracting members is four and the four magnetic attracting members are arranged at four corners of the base plate.

[0036] In this embodiment, the light-transmitting hole 10 is arranged at the center of the plane of the substrate 1. The light-transmitting hole is arranged coaxially with the bolt hole.

[0037] The image collector 2 is mounted on the substrate 1 and is aligned with the light-transmitting hole 10 .

[0038] As a preferred embodiment, the image collector 2 is a camera, and the camera is coaxially arranged with the light-transmitting hole.

[0039] The display is installed in the driver's cab of the lifting machine. The display signal is connected to the image collector 2.

[0040] In this embodiment, the display is a liquid crystal screen, or a mobile terminal such as a mobile phone or a computer.

[0041] As a preferred embodiment, the aperture of the light-transmitting hole 10 is larger than the aperture of the bolt hole. The substrate 1 is installed with a hole locker 3. The hole locker 3 is used to lock the substrate 1.

[0042] Specifically, the hole locker 3 includes a wall-adhering plate 31 and a driving screw 32 .

[0043] There are multiple wall-attached plates 31. In this embodiment, there are two wall-attached plates 31.

[0044] The two wall-attached plates 31 are arranged opposite to each other. The two wall-attached plates 31 are movably arranged in the light-transmitting hole 10. The lower part of the wall-attached plates 31 extends to the lower part of the light-transmitting hole 10.

[0045] Two threaded sleeves 33 are installed on the upper surface of the substrate 1. Each threaded sleeve is screwed to one end of a driving screw 32. The upper part of the wall-attached plate 31 extends above the light-transmitting hole 10 and is rotatably installed on the other end of the driving screw 32.

[0046] After the driving screws 32 in the two threaded sleeves are rotated, the two wall-adhering plates 31 move away from each other and press against the hole walls on opposite sides of the bolt hole.

[0047] As a preferred implementation, the wall-attached plate is arc-shaped.

[0048] As a preferred embodiment, the visual auxiliary steel structure hoisting device of the present invention further includes a controller. The controller signal is connected to the image collector 2 and the display. A sensor is installed at the lower part of the two wall panels 31. An alarm is installed in the driver's cab.

[0049] After the column foot bolts extend between the two wall panels 31, the sensor generates an alignment signal, and the controller obtains the alignment signal and turns on the alarm.

[0050] In this embodiment, the sensor is an infrared sensor. When the column foot bolt is aligned with the bolt hole and extends between the two wall panels during the hoisting of the steel structure, the sensor generates an alignment signal to remind the driver. The controller obtains the alignment signal and turns on the alarm, which emits an audible and visual alarm to remind the driver or operator.

[0051] The construction method of the visualization-assisted steel structure hoisting device of the present invention comprises the following steps:

[0052] S1.

[0053] When the base plate is installed on the upper surface of the steel column foot bottom plate, after the magnetic attraction piece is magnetically attracted to the base plate, the two wall-attached plates are pressed against the hole wall of the bolt hole by rotating the driving screw.

[0054] Through the coordinated adjustment of the two driving screws, the camera on the base plate can be aligned with the bolt hole, and the base plate can be locked simultaneously with the magnetic suction piece, thereby improving the installation stability of the base plate and the camera.

[0058] S5. After the column foot bolts extend between the two wall panels 31, the sensor generates an alignment signal.

[0059] S6. The controller obtains the alignment signal and turns on the alarm.

[0060] When hoisting steel components, when the column foot bolts are aligned with the bolt holes and extend between the two wall panels, the sensor generates an alignment signal to remind the driver. The controller obtains the alignment signal and turns on the alarm, which emits an audible and visual alarm to remind the driver or operator.

[0061] The visualization-assisted steel structure hoisting device of the present invention installs a base plate on the bottom plate of the steel structure column foot so that the image collector on the base plate can collect the relative positions of the column foot bolts and the bolt holes on the bottom plate of the steel structure column foot during the hoisting process, so that the driver or operator in the driver's cab of the hoisting machinery can grasp and understand the relative positions of the column foot bolts and the bolt holes on the bottom plate of the steel structure column foot in real time, avoiding the need for retelling and command by ground personnel, thereby improving the hoisting and installation efficiency of steel components and reducing the labor cost of steel structure construction.
