[0034] Please refer to the attached document. Figures 1-5 This paper illustrates a lifting and limiting device for a steel space frame installation platform provided in an embodiment of this application. This device assists in the installation of the steel space frame and includes a housing 1, a distance measuring module, and a magnetic suction component 2. The distance measuring module is installed on the top of the housing 1 and measures the distance between the lifting and limiting device and the bottom of the steel space frame installation platform. A magnetic suction component 2 is fixedly installed on the side of the housing 1 to quickly fix the housing 1 to the side of a hydraulic jack (generally, the protective shell of a hydraulic jack is made of metal). The data output terminal of the distance measuring module is communicatively connected to the control system of the hydraulic jack.

[0035] The control system of the hydraulic jack controls the lifting operation of the hydraulic jack. During the process of lifting the steel grid installation platform, the distance measuring module measures and provides feedback on the lifting height of the steel grid installation platform driven by the hydraulic jack in real time. When the limit distance is reached, the control system of the hydraulic jack stops the lifting operation to ensure the safety of the steel grid installation platform lifting process. Compared with traditional mechanical blocks and manual monitoring, its limit accuracy is high and does not rely on the user's experience.

[0036] In one embodiment, the ranging module includes: an annular fixing sleeve 5 fixedly installed on the top of the housing 1, an optical ranging element 6, and an angle adjustment assembly.

[0037] A circular hole is provided on the top of the housing 1, corresponding to the center of the annular fixing sleeve 5. The outer side of the optical rangefinder 6 is fixedly connected to the inner side of the annular fixing sleeve 5 through an elastic ring, so that the optical rangefinder 6 can be finely adjusted relative to the annular fixing sleeve 5. The optical rangefinder 6 is a high-sensitivity infrared probe. The bottom of the optical rangefinder 6 corresponds to the circular hole, which facilitates the installation of the angle adjustment component and the wiring harness of the optical rangefinder 6. An angle adjustment component is provided between the bottom of the optical rangefinder 6 and the housing 1. The angle adjustment component is used to adjust the angle of the optical rangefinder 6.

[0038] The housing 1 is fixed to the outside of the hydraulic jack using the magnetic suction component 2. However, it is impossible to ensure that the optical rangefinder 6 is in a vertical position when it is fixed. Therefore, after the housing 1 is fixed to the outside of the hydraulic jack, the user can adjust the angle of the optical rangefinder 6 through the angle adjustment component to make the optical rangefinder 6 in a vertical position.

[0039] In one embodiment, the angle adjustment assembly specifically includes: an adjustment plate 7, an elastic plate 8, and an adjustment screw 9.

[0040] The top of the adjusting plate 7 is fixedly connected to the bottom of the optical rangefinder 6. The adjusting plate 7 is preferably a T-shaped structure to reduce the deformation of the adjusting plate 7 itself. The bottom of the adjusting plate 7 is provided with an inverted U-shaped opening 7a. One end of the elastic plate 8 is fixedly connected to the inner wall of the housing 1, and the other end of the elastic plate 8 is fixedly connected to the adjusting plate 7. The elastic plate 8 is used to maintain the position of the adjusting plate 7, and the elastic plate 8 itself can deform without affecting the movement of the adjusting plate 7 under force. The adjusting screw 9 is threadedly connected to the side wall of the housing 1, and the adjusting screw 9 is slidably engaged with the inverted U-shaped opening 7a.

[0041] The user rotates the adjusting screw 9, which pulls / pushes the bottom of the adjusting plate 7 to move. The optical rangefinder 6 is restricted by the elastic ring, so the top moves only slightly. In this way, the adjusting plate 7 is adjusted in angle. The adjustment is completed when the top of the optical rangefinder 6 is in a horizontal state.

[0042] In one embodiment, the ranging module further includes an indicator light 3, a wiring terminal 4, and a processor 10. The indicator light 3 and the wiring terminal 4 are fixedly disposed on the outside of the housing 1, and the processor 10 is fixedly disposed on the inside of the housing 1.

[0043] Indicator 3 indicates the power supply signal, showing whether the ranging module is powered on. Terminal 4 facilitates connection of power supply lines and signal transmission lines. Processor 10 is a built-in data processing unit of the ranging module, used to process the signals emitted and received by the optical ranging device 6. It is currently a standard component of the optical ranging device 6.

[0044] In one embodiment, the top of the housing 1 is provided with a protective enclosure 1a that surrounds the ranging module. The protective enclosure 1a is used to protect the ranging module and prevent it from being damaged by physical collision.

[0045] In one embodiment, a reflector 11 is also designed. In order to improve the reflection of more light beams after the optical rangefinder 6 illuminates the bottom of the steel grid mounting platform and ensure the ranging effect, the reflector 11 is fixedly installed at the bottom of the steel grid mounting platform corresponding to the position of the optical rangefinder 6.
