Specific implementation mode

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0029] Example 1: As Figures 1 to 6 shown, a support system for an aerial work platform with adjustable height according to an embodiment of the present invention includes a horizontal steel beam 7. A concrete silo wall 1 is arranged on the right side of the horizontal steel beam 7. The horizontal steel beam 7 is fixedly installed with the concrete silo wall 1 through a fastening component;

[0030] A through-type adjusting groove is opened above the interior of the horizontal steel beam 7. A vertical steel beam 4 is arranged inside the adjusting groove. A plurality of uniformly distributed and through-type first adjusting holes 3 are opened on the front and rear surfaces inside the adjusting groove. A first adjusting bolt 2 penetrates through the first adjusting hole 3. A first nut is threadedly connected to the rear outer surface of the first adjusting bolt 2. The rear end of the first adjusting bolt 2 penetrates through the vertical steel beam 4;

[0031] A through-type slot is opened below the interior of the horizontal steel beam 7. A diagonal bracing steel beam 8 is inserted into the slot. A second installation bolt 11 penetrates through the slot. The second installation bolt 11 penetrates through the diagonal bracing steel beam 8. A second nut is threadedly connected to the rear outer surface of the second installation bolt 11;

[0032] An adjusting component is provided between the diagonal bracing steel beam 8 and the vertical steel beam 4, and a reinforcing component 6 is provided between the concrete silo wall 1 and the vertical steel beam 4. During operation, a triangular frame structure is formed by the transverse steel beam 7, the vertical steel beam 4, and the diagonal bracing steel beam 8. The vertical steel beam 4 is composed of 8# channel steel, the transverse steel beam 7 is composed of 63 angle steel, and the diagonal bracing steel beam 8 is composed of 63 angle steel. The transverse steel beam 7 can be fixedly installed with the concrete silo wall 1 through the fastening component. Then, the vertical steel beam 4 is fixedly installed with the transverse steel beam 7 through the threaded connection of the first adjusting bolt 2 and the first nut. The height of the vertical steel beam 4 can be adjusted by passing the first adjusting bolt 2 through the first adjusting holes 3 at different positions. The diagonal bracing steel beam 8 can adapt to the height adjustment of the vertical steel beam 4 through the adjusting component. Since the transverse steel beam 7 is fixedly installed with the diagonal bracing steel beam 8 through the threaded connection of the second installing bolt 11 and the second nut, the diagonal bracing steel beam 8 can rotate to adapt to the height adjustment of the vertical steel beam 4 when the height of the vertical steel beam 4 is adjusted. Then, the reinforcing component 6 can increase the supporting strength of the platform support system and make it safer. At the same time, the triangular frame structure itself has the characteristic of high stability. The vertical steel beam 4 and the diagonal bracing steel beam 8 are evenly distributed and are hingedly connected to the transverse steel beam 7 in pairs to form a geometrically invariant body. When bearing loads, it can maintain its geometric shape and position unchanged and will not produce rigid body motion, thereby effectively dispersing the weight of the aerial work platform, reducing shaking. The height adjustment of the vertical steel beam 4 can quickly adjust the height range of the triangular frame and can meet the requirements of different working heights. In this way, a safe working environment can be provided for the staff through the stable triangular frame structure and reliable adjusting device, reducing the risk of accidents. At the same time, the vertical steel beam 4 is detachably connected to the transverse steel beam 7 and the diagonal bracing steel beam 8, facilitating disassembly, transportation, storage, and installation for use.

[0033] The reinforcing component 6 includes reinforcing plates 61 integrally formed on the front and rear surfaces of the transverse steel beam 7.

During operation, the reinforcing plates 61 are fixedly installed with the concrete silo wall 1 through the threaded connection of the second fastening bolts 66 penetrating the reinforcing plates 61 and the second embedded sleeves 67 fixedly installed inside the concrete silo wall 1. The contact area of the supporting surface between the transverse steel beam 7 and the concrete silo wall 1 can be increased through the integral formation of the reinforcing plates 61 and the transverse steel beam 7. Then, in cooperation with the supporting component, the supporting strength of the vertical steel beam 4 is higher, so that the overall supporting structure of the platform support system is more stable.

[0034] The support assembly includes connection blocks 63 fixedly connected to the front and rear surfaces of the vertical steel beam 4. A groove is formed on the left side of the reinforcement plate 61. A support plate 64 is inserted into the groove.

A plurality of uniformly distributed and through adjustment holes two 68 are formed in the support plate 64. An adjustment bolt two 65 penetrates through the adjustment holes two 68. The adjustment bolt two 65 is threadedly connected to the connection block 63. During operation, the support plate 64 is installed on the reinforcement plate 61 through the first installation bolt 62. The support for the vertical steel beam 4 is strengthened by the support plate 64, and the load of the vertical steel beam 4 is distributed by the support plate 64. Then, the support plate 64 is connected to the vertical steel beam 4 through the threaded connection of the adjustment bolt two 65 penetrating through the adjustment holes two 68 and the connection block 63. By passing the adjustment bolt two 65 through the adjustment holes two 68 at different positions, the height adjustment of the vertical steel beam 4 can be adapted, so that the support strength of the vertical steel beam 4 is higher, the support effect of the platform support system is better, and the support strength is strengthened.

[0035] The rear end of the first installation bolt 62 penetrates through the support plate 64 and is threadedly connected to the rear surface inside the groove. The front end of the first installation bolt 62 penetrates through the front surface of the reinforcement plate 61. The support plate 64 is movably connected to the groove. During operation, the support plate 64 inserted into the groove is fixedly installed through the first installation bolt 62. The disassembly and installation of the support plate 64 and the groove are also facilitated by the first installation bolt 62. At the same time, since the first installation bolt 62 penetrates through the inside of the support plate 64 and is located inside the groove, it is convenient to adjust the rotation position of the support plate 64 when adjusting the vertical steel beam 4.

[0036] The adjustment assembly includes a through slot formed on the left side inside the vertical steel beam 4. The top of the diagonal bracing steel beam 8 is inserted into the slot. A plurality of uniformly distributed and through adjustment holes three 9 are formed above the inside of the diagonal bracing steel beam 8.

A plurality of first embedded sleeves 12 are arranged inside the concrete bin wall 1 corresponding to the transverse steel beam 7. The first fastening bolts 5 are in threaded connection with the first embedded sleeves 12. During operation, the transverse steel beam 7 can be fixedly installed on the concrete bin wall 1 through the threaded connection between the first fastening bolts 5 penetrating through the transverse steel beam 7 and the first embedded sleeves 12 fixedly installed inside the concrete bin wall 1 to provide stable support.

[0038] The top and bottom of the diagonal bracing steel beam 8 and the top and bottom of the support plate 64 are both arranged in an arc shape. During operation, it is convenient for the diagonal bracing steel beam 8 and the support plate 64 to rotate in position during adjustment.
