[0091] This embodiment provides an adjustable large-span operation platform 4 based on the Internet of Things. In addition to the technical solutions of the above embodiments, it also has the following technical features. The column support 3 includes:

[0092] A plurality of telescopic rods 30 are provided, and two of them are connected between two adjacent support columns 2 in a group with equal intervals;

[0096] The second locking member 32 may be a bolt and a nut.

[0097] It can be seen from this embodiment that the spacing between two adjacent support columns 2 can be better adapted by adopting the arrangement of the telescopic rod 30, which effectively improves the convenience of installation and construction, and the arrangement of the reinforcing rod 31 effectively ensures that the inter-column support 3 promotes the structural stability of the support column 2, and at the same time, the second locking member 32 can lock the telescopic rod 30, so as to ensure structural stability;

The fine-tuning assembly 33 can effectively improve the alignment of the second reduction member with the mounting hole on the telescopic rod 30, thereby effectively improving convenience.

[0099] Embodiment 5:

[0100] This embodiment provides an adjustable large-span operating platform 4 based on the Internet of Things, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0101] The telescopic rod 30 includes a sub-rod 300 and a mother rod 301, and the fine-tuning assembly 33 includes:

[0102] The convex strip 330 is installed on the surface of the sub-rod 300 and has teeth on the surface, and a strip groove 334 matching the convex strip 330 is formed on the mother rod 301;

[0103] The gear 331 is installed in the mother rod 301 and meshes with the teeth;

[0104] The rotating shaft 332 is installed in the mother rod 301 and is used for installing and driving the gear 331;

[0105] The knob 333 is mounted on the surface of the mother rod 301 and connected to the rotating shaft 332;

[0106] There are two convex strips 330, which are arranged on one side of the sub-rod 300 in correspondence with each other, and teeth are arranged on one convex strip 330;

[0107] Specifically, a connecting block is provided on the inner wall of the mother rod 301 and between the two protrusions 330, and a mounting groove is opened on the side of the connecting block close to the sub-rod 300, and the gear 331 is located in the mounting groove, and the two ends of the rotating shaft 332 are respectively rotatably connected to the inner wall of the mounting groove and the mother rod 301, and one end extends out of the mother rod 301 and is clamped with the knob 333.

[0108] It can be seen from this embodiment that the knob 333 is used to drive the rotating shaft 332 to rotate, and the gear 331 is driven to engage the teeth on the protruding strip 330, thereby driving the sub-rod 300 to move, so that the operator can control the fine-tuning distance and the convenience of locking the telescopic rod 30 is improved;

[0109] In addition, the provision of the convex strip 330 can effectively improve the structural strength of the sub-rod 300 , and the cooperation between the convex strip 330 and the strip groove 334 can effectively improve the stability of the telescopic rod 30 during adjustment, making it easier for the second locking member 32 to align with the mounting hole on the telescopic rod 30 .

[0110] Embodiment 6:

[0111] This embodiment provides an adjustable large-span operating platform 4 based on the Internet of Things. In addition to the technical solutions of the above embodiments, it also has the following technical features. The leveling mechanism 7 includes:

[0112] The lower bracket 70 is mounted on the support column 2 and has a plurality of lifting cylinders 71 installed around the circumference;

[0113] An upper bracket 72 is mounted on the output end of the lifting cylinder 71;

[0114] A universal joint 73 is connected to the output end of the lifting cylinder 71 and is used for connecting the lifting cylinder 71 and the upper bracket 72;

[0115] Wherein, the plurality of lifting cylinders 71 are all communicatively connected to the control system;

[0116] At the same time, the lifting cylinder 71 can be a hydraulic cylinder, and the hydraulic cylinder is connected to the control system by radio. Specifically, a sensor and a wireless communication module are installed on the hydraulic cylinder. The sensor is used to collect the working status, pressure, displacement and other parameters of the hydraulic cylinder, and transmit these data to the control system in real time through the wireless communication module. The control system can send control instructions to the hydraulic cylinder through the wireless communication module to remotely control the hydraulic cylinder.

[0117] It can be seen from this embodiment that the stability of the installation of multiple lifting cylinders 71 is improved by the arrangement of the lower bracket 70 and the upper bracket 72, and the arrangement of the universal joint 73 is adopted. When the upper bracket 72 is leveled by the lifting cylinder 71 after the base 1 and the support column 2 are tilted at a small angle due to ground settlement, the angle between the lifting cylinder 71 and the upper bracket 72 can be offset to ensure the leveling of the upper bracket 72 and avoid obstruction.

[0118] By connecting the lifting cylinder 71 to the control system through communication, the convenience of driving the lifting cylinder 71 is improved.

[0121] A connecting column 730, axially mounted on the output end of the lifting cylinder 71;

[0122] The ball 731 is installed at the end of the connecting column 730 away from the lifting cylinder 71;

[0123] The upper ball cover 732 is wrapped around the ball body 731 and connected to the upper bracket 72 via a connecting tube 733;

[0124] The lower ball cover 734 is wrapped around the sphere 731 and connected to the upper ball cover 732, and a first circular hole 735 is opened at one end close to the lifting cylinder 71;

[0125] The diameter of the first circular hole 735 is larger than the diameter of the connecting column 730;

[0126] At the same time, the connecting column 730 and the output end of the lifting cylinder 71 can be connected by threads, and the upper ball cover 732 and the lower ball cover 734 can be connected by bolts, and the upper ball cover 732 and the connecting tube 733 are welded, and the connecting tube 733 and the upper bracket 72 are connected by bolts.

[0127] It can be seen from the present embodiment that by providing a connecting column 730 with a sphere 731 at the output end of the lifting cylinder 71, and axially limiting the connecting column 730 through the upper ball cover 732 and the lower ball cover 734, when the lifting heights of multiple lifting cylinders 71 are the same, the stability of the upper bracket 72 installed on the lifting cylinder 71 can be effectively guaranteed, and the first circular hole 735 on the lower ball cover 734 can facilitate the rotation of the connecting column 730 in its radial direction, thereby avoiding radial limitation of the connecting column 730 by the lower ball cover 734.

[0128] Embodiment 8:

[0129] This embodiment provides an adjustable large-span operating platform 4 based on the Internet of Things. In addition to the technical solutions of the above embodiments, it also has the following technical features. The detection mechanism 6 includes:

[0130] The box body 60 is mounted on the bottom surface of the upper bracket 72 and forms a chamber inside;

[0131] A slideway 61 is installed in the chamber, and is provided in plurality and arranged at equal intervals around the circumference;

[0132] A second slider 62 is slidably connected in the slideway 61;

[0133] The spring 63 is installed in the slideway 61 and is located on both sides of the second slideway 62 along the sliding direction of the second slideway 62, and the two ends of the spring 63 are respectively in contact with the second slideway 62 and the inner wall of the slideway 61;

[0134] The block 64 is installed in the box body 60 and is used to limit the position of the slideway 61 when it is installed;

[0135] A plurality of second circular holes 65 arranged at equal intervals are opened on the inner wall of the slideway 61 at the second slider 62, and a plurality of photoelectric sensors 66 are installed at the second circular holes 65, and a light shielding plate 67 for shielding the light propagation of the photoelectric sensors 66 is installed on the second slider 62;

[0136] At the same time, in order to effectively reduce the friction resistance when the second slider 62 slides, the material of the slideway 61 and the second slider 62 can be made of a material with a low surface friction coefficient and polished accordingly, which is a prior art and will not be repeated here;

[0137] Furthermore, the elastic force of the spring 63 should not be too large, that is, it will not significantly affect the sliding of the second sliding block 62 , and the detection mechanism 6 is arranged in the center relative to the support column 2 as a whole.

[0138] It can be seen from the present embodiment that by adopting the arrangement of multiple slideways 61 on the circumference and arranging a sliding second slider 62 in the slideway 61, when the operating platform 4 tilts due to ground settlement, the second slider 62 will slide in the slideway 61, thereby driving the shading plate 67 to move, thereby releasing the shielding of part of the photoelectric sensor 66, and the receiver of the photoelectric sensor 66 receives the light of the generator, thereby providing feedback, and the specific number of photoelectric sensors 66 receiving the light corresponding to the tilt angle of the operating platform 4 can be obtained through actual experiments, which is a prior art and will not be repeated here;

[0139] Furthermore, the provision of the spring 63 can prevent the second slider 62 from rigid collision, thereby avoiding damage and extending the service life, while at the same time limiting the movement of the second slider 62 within a certain range.

[0140] Embodiment 9:

[0141] This embodiment provides an adjustable large-span operating platform 4 based on the Internet of Things, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0142] The number of slideways 61 arranged at equal intervals around the circumference is 2n, where n is a positive integer;

[0143] Here, n in the present application is four, that is, the number of slideways 61 is 8.

[0144] It can be seen from the present embodiment that by setting the conveying of the slide 61 to 2n, where n is a positive integer, there are two slides 61 in opposite directions in a radial direction, which causes the second slider 62 in one slide 61 to slide away from the axial direction, and the second slider 62 in the other slide 61 to slide close to the axial direction. This can avoid the situation where, when the sliding of one of the second sliders 62 is blocked due to an unexpected situation, the inclination of the operating platform 4 can be known through the sliding of the second slider 62 in the other corresponding slide 61, thereby improving security. At the same time, when the sliding of the second sliders 62 in the two slides 61 is not blocked, they can be verified with each other to ensure the effectiveness and accuracy of the detection mechanism 6 in detecting the inclination of the operating platform 4, thereby ensuring safety.

[0145] Embodiment 10:

[0146] This embodiment provides an adjustable large-span operating platform 4 based on the Internet of Things. In addition to the technical solutions of the above embodiments, it also has the following technical features. The control system includes:

[0147] A control module, used to receive feedback from the detection mechanism 6 and process the data;

[0148] Networking module, used to connect to the Internet of Things and transmit data;

[0149] A setting module, used to set the angle range within which the operating platform 4 is allowed to tilt;

[0150] The simulation module, after receiving the feedback from the detection mechanism 6 through the control module, simulates the tilt of the operating platform 4, and feeds back to the control module according to the tilt of the simulated operating platform 4, and the control module controls the leveling mechanism 7 to level the operating platform 4;

[0151] An operating terminal, used for manually controlling the leveling mechanism 7;

[0152] Among them, the specific structure of each module is the existing technology, which only needs to achieve the function and will not be described here.

[0153] It can be seen from the present embodiment that the control module facilitates the feedback and processing of the received data, and the simulation module presents it on the display screen of the operating terminal, so that the workers can more clearly understand the situation of the operating platform 4. At the same time, the operating terminal allows remote operation and control of the lifting cylinder 71, so as to level the operating platform 4, effectively improving the convenience. At the same time, according to the setting module, the control module can be based on the set value. When the actual data exceeds the set value, it can automatically control part of the lifting cylinder to work, so as to level the operating platform 4 and ensure safety.
