The rotating connection assembly connects the two support rods with the help of a connecting plate and two rotating shafts to control the folding support rod to rotate around the axis to adjust the support height as needed. The limit fixing assembly uses an L-shaped mounting plate, a limit pin rod, etc. When supporting horizontally, the spring pushes the pin rod to fix it, and when folding, the lifting handle is pulled to release the fixation for easy folding. However, the folding support rod in the device in the patent document is relatively simple, the adjustable spacing is limited, and the stability is poor.

DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 6As shown: a high compressive strength floor support device with automatic spacing adjustment function, including a secondary beam 1, an I-beam 2 and a support rod 3, the secondary beam 1 is fixedly arranged above the I-beam 2; the support rod 3 is installed at the bottom of the I-beam 2, and an adjustment mechanism 4 is arranged at the bottom of the support rod 3; the adjustment mechanism 4 includes a movable groove 41 and an adjustment rod 42; the movable groove 41 is opened at the bottom of the support rod 3; the adjustment rod 42 is slidably connected with the support rod 3 through the movable groove 41, and the side walls of the support rod 3 and the adjustment rod 42 are opened with a limited slot 43; a plurality of limited slots 43 are opened on the support rod 3; a limited plug 44 for fixing the position of the adjustment rod 42 is inserted in the limited slot 43.

[0027] In the prior art, the support device usually has a fixed spacing, which cannot be flexibly adjusted and is difficult to adapt to changes in different sizes and load conditions. To address this problem, when the spacing of the floor support device needs to be adjusted, the adjustment mechanism 4 is used for adjustment. The adjustment rod 42 is slidably connected to the support rod 3 through the movable groove 41, and the adjustment rod 42 moves along the movable groove 41, thereby changing the height of the entire support device. After the adjustment is in place, the limit plug 44 is inserted into the corresponding limit slot 43. Since there are multiple limit slots 43 on the support rod 3, the limit slot 43 of the appropriate height can be selected according to the adjustment requirements to insert the limit plug 44, thereby fixing the position of the adjustment rod 42 and ensuring that the support device remains stable during use. The secondary beam 1 is fixed above the I-beam 2, and the two jointly bear the floor pressure, and the adjustment mechanism 4 at the bottom of the support rod 3 ensures that the entire device can be flexibly adjusted as needed to adapt to different working conditions. The support rod 3 installed at the bottom of the I-beam 2 and its adjustment mechanism 4 provide reliable support for the entire support system.

[0028] Reference Figure 5 and Figure 6 As shown, a guide rod 411 is arranged in the movable groove 41 ; a guide groove 421 is opened on the adjusting rod 42 ; and the guide rod 411 is inserted into the guide groove 421 .

[0029] Since the adjusting rod 42 is provided with a guide groove 421 and the guide rod 411 is inserted in the guide groove 421, when the adjusting rod 42 moves, the guide rod 411 limits the adjusting rod 42 to slide only along the preset direction of the guide groove 421, thereby preventing the adjusting rod 42 from being deflected or tilted in the moving groove 41 and other unstable situations, thereby ensuring the accuracy of the moving trajectory of the adjusting rod 42 and making the entire spacing adjustment operation more stable and smooth. In cooperation with the limit plug 44 and the limit slot 43, it is further ensured that the supporting device can stably and reliably perform the high compressive strength supporting function under different working conditions, thereby helping the secondary beam 1 and the I-beam 2 to better bear the floor pressure.

[0030] Reference Figure 1-Figure 6As shown: a positioning mechanism 5 is arranged between the support rod 3 and the I-beam 2; the positioning mechanism 5 has a clearance hole 51, a positioning block 52 and a tension bolt 53; a plurality of clearance holes 51 are provided on the I-beam 2; the positioning block 52 is slidably connected to the I-beam 2, and a connecting through hole 521 is provided on the side wall of the positioning block 52; when the connecting through hole 521 of the positioning block 52 corresponds to the clearance hole 51 on the I-beam 2, the tension bolt 53 can pass through the connecting through hole 521 and the clearance hole 51 at the same time.

[0031] The I-beam 2 is provided with a plurality of clearance holes 51, and the positioning block 52 is slidably connected to the I-beam 2. The positioning block 52 is moved so that the connecting through hole 521 of the side wall is aligned with the clearance hole 51 at a suitable position. When the connecting through hole 521 is aligned with the clearance hole 51, the tension bolt 53 can simultaneously pass through the connecting through hole 521 and the clearance hole 51 to fix the positioning block 52 with the I-beam 2, thereby determining the position of the support rod 3 relative to the I-beam 2, avoiding displacement or shaking of the support rod 3 during use, ensuring the stability of the entire support device structure, and combining with the adjustment mechanism 4 and other components, the secondary beam 1, the I-beam 2, and the support rod 3 work together to provide reliable high compressive strength support for the floor slab, adapting to various working conditions.

[0032] Reference Figure 1-Figure 4 As shown: a rotating mechanism 6 is arranged between the positioning block 52 and the support rod 3; the rotating mechanism 6 includes a rotating block 61, a rotating slot 62 and a rotating shaft 63; the rotating block 61 is fixedly arranged at the bottom of the positioning block 52; the rotating slot 62 is opened at the top of the rotating block 61 and the support rod 3; the rotating shaft 63 can simultaneously pass through the rotating slot 62 on the rotating block 61 and the rotating slot 62 on the support rod 3.

[0033] The bottom of the positioning block 52 is fixedly connected with a rotating block 61. The rotating block 61 and the top of the support rod 3 are both provided with a rotating slot 62. The rotating shaft 63 can pass through the rotating slots 62 of the two at the same time, so that the rotating block 61 can flexibly rotate relative to the support rod 3 with the rotating shaft 63 as the axis. This feature enables the positioning block 52 to adjust its position in coordination with the I-beam 2. Even if the I-beam 2 has a certain angle deviation or there are special requirements for the installation scene, the positioning block 52 can adaptively change its angle through the rotation of the rotating block 61 to ensure that the connecting through hole 521 of its side wall is accurately aligned with the corresponding clearance hole 51 on the I-beam 2, which is convenient for the subsequent tightening of the tension bolt 53, thereby stably fixing the support rod 3, coordinating with the adjustment mechanism 4 and other components, and providing stable support for the bearing system composed of the secondary beam 1 and the I-beam 2, ensuring that the floor support device can efficiently cope with various complex working conditions.

[0034] Reference Figure 5 As shown: an auxiliary pull ring 7 is provided on the limiting plug block 44.

[0035] The operator can hook the auxiliary pull ring 7 with his fingers or tools to more easily grasp the limit plug 44, and accurately and effortlessly insert it into the corresponding support rod 3 and the limit slot 43, avoiding insertion difficulties or position deviations caused by the small size of the limit plug 44 and difficulty in applying force, and ensuring that the adjustment rod 42 can be quickly and firmly fixed.

[0036] Reference Figure 1 As shown: a plurality of support rods 3 are arranged along the I-beam 2 .

[0037] Arranging multiple support rods 3 along the length direction of the I-beam 2 can greatly improve the overall support performance. Multiple support rods 3 are evenly distributed, dispersing and transmitting the pressure from the floor to the I-beam 2, avoiding excessive force at a single point, and making the pressure distribution more balanced.

[0038] Reference Figure 1-Figure 6 As shown: a supporting foot 8 is provided at the bottom of the adjusting rod 42.

[0039] When the entire support device is installed in place, the support foot 8 directly contacts the ground or the support surface, increasing the contact area between the bottom of the adjustment rod 42 and the support surface, effectively dispersing the pressure from above on the adjustment rod 42, and preventing it from sinking into the soft ground or causing local damage to the support surface.

[0040] The secondary beam 1 is a square steel structure.

[0041] In the floor support device, the secondary beam 1 adopts a square steel structure. The square steel itself has a regular shape, a stable structure, and good mechanical properties. When bearing the load transmitted from the floor, it can evenly disperse the pressure by virtue of its stable cross-sectional shape, effectively transfer the load to the I-beam 2, and cooperate with the I-beam 2. Because of its high structural strength, it can better resist bending, deformation, etc., and ensure the structural stability of the entire support device when it is subjected to high compressive strength requirements. In the high compressive strength floor support device with automatic spacing adjustment function, the secondary beam 1 is arranged above the I-beam 2 and the two are fixedly connected to jointly bear the floor pressure. The support rod 3 is installed at the bottom of the I-beam 2 and an adjustment mechanism 4 is provided at its bottom. The adjustment rod 42 of the adjustment mechanism 4 is slidably connected to the support rod 3 through a moving groove 41. The height of the device can be changed by moving the adjustment rod 42, and the position of the adjustment rod 42 is fixed by using a limiting slot 43 and a limiting plug 44. Because there are multiple limiting slots 43, a suitable insertion and fixing can be selected as needed to ensure that the device is stable and can be flexibly adjusted to adapt to different working conditions. The guide rod 411 in the moving groove 41 is inserted into the guide groove 421 of the adjusting rod 42 to limit the sliding direction of the adjusting rod 42, ensuring the accuracy of the adjustment trajectory and making the spacing adjustment smoother and more stable. The positioning mechanism 5 between the support rod 3 and the I-beam 2 is connected to the I-beam 2 through the positioning block 52 and the connecting through hole 521 is aligned with the clearance hole 51 of the I-beam 2, and then the tension bolt 53 is passed through and tightened to determine the position of the support rod 3 to avoid displacement and shaking, thereby ensuring the stability of the structure. The rotating mechanism 6 between the positioning block 52 and the support rod 3 cooperates with the rotating block 61, the rotating slot 62 and the rotating shaft 63, so that the rotating block 61 can rotate relative to the support rod 3, which is convenient for the positioning block 52 to adapt to the angle change, so that the connecting through hole 521 is accurately aligned with the clearance hole 51 to tighten the support rod 3, and cooperate with other components to cope with complex working conditions. The auxiliary pull ring 7 on the limit plug block 44 is convenient for the operator to hold the plug block, and accurately and labor-savingly insert the limit slot 43 to ensure that the adjusting rod 42 is firmly fixed. Multiple support rods 3 are arranged along the length direction of the I-beam 2 to disperse and transmit the floor pressure, making the pressure distribution more balanced and improving the overall support performance. The support foot 8 at the bottom of the adjustment rod 42 contacts the support surface, increasing the contact area, dispersing the pressure, and preventing it from sinking into the soft ground or damaging the support surface. The secondary beam 1 adopts a square steel structure. With its regular shape, stable structure and good mechanical properties, it evenly distributes the load to the I-beam 2, resists bending deformation, and ensures the structural stability of the device when it is subjected to high compressive strength.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
