[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figures 1 to 2 As shown, the utility model proposes an edge protection device based on a disc-type frame system, comprising a disc-type connector 1, on which a square steel tube 2 is fixedly mounted, a horizontal adjustment rod 3 is slidably mounted in the square steel tube 2, a square steel vertical rod 5 is fixedly mounted on the horizontal adjustment rod 3, and a plurality of square steel cross bars 4 are fixedly mounted on the square steel vertical rod 5. The disc-type connector 1 serves to connect with the disc-type frame. The square steel tube 2 is an integral part of the disc-type connector 1 and serves to fix the guardrail. The horizontal adjustment rod 3 is inserted into the square steel tube 2 and serves to fix the guardrail. The square steel cross bar 4 is the horizontal bar of the guardrail. The square steel vertical rod 5 is the vertical bar of the guardrail.

[0029] The square steel tube 2 is connected to the support frame through the disc-shaped connector 1. The horizontal adjustment rod 3, the square steel cross bar 4, and the square steel vertical bar 5 are an integral protective railing. The square steel cross bar 4 and the square steel vertical bar 5 are connected by bolts, and the horizontal adjustment rod 3 and the square steel vertical bar 5 are connected by welding.

[0030] This device is assembled as a whole and can be turned around. Compared with ordinary frame erection, it can achieve the effect of reducing materials and labor, and speeding up construction. This method is based on the original plate buckle frame system and optimized design to achieve the technical requirement of the external protective frame not falling to the ground.

[0031] like Figures 3 to 9As shown, this embodiment also includes a distance adjustment mechanism, which is installed on the square steel tube 2 and the horizontal adjustment rod 3. The distance adjustment mechanism fixes the horizontal adjustment rod 3 at any position. The distance adjustment mechanism includes a slide 7 provided on the horizontal adjustment rod 3, in which a slider 8 is slidably installed. The slider 8 is provided with a plurality of through holes 9. The slider 8 is fixedly connected to the square steel tube 2 by a fastening bolt 6, and the fastening bolt 6 passes through the through holes 9. By fixing the slider 8 to the square steel tube 2 by the fastening bolt 6, the horizontal adjustment rod 3 can be slidably connected to the square steel tube 2. When the slider 8 cannot slide equally with the horizontal adjustment rod 3, the horizontal adjustment rod 3 will be fixedly connected to the square steel tube 2. This device can be designed according to actual conditions to allow the horizontal adjustment rod 3 to slide freely on the square steel tube 2, which can meet construction needs under various conditions.

[0032] Furthermore, the distance adjustment mechanism also includes two sleeves 10 fixedly installed in the horizontal adjustment rod 3, and a limit rod 11 is slidably installed in the sleeve 10. The two limit rods 11 are respectively fixedly connected to the two ends of the slider 8. A sealing ring is installed between the limit rod 11 and the sleeve 10. The two sleeves 10 are connected through an oil pipe 12. The sleeve 10 and the oil pipe 12 are filled with hydraulic oil, and a valve structure is installed in the oil pipe 12. When the valve mechanism is opened, when the slider 8 slides freely on the horizontal adjustment rod 3, it will drive the limit rods 11 on both sides to move, and the limit rods 11 will squeeze or release the space inside the sleeve 10. When the slider 8 moves to the left, the hydraulic oil inside the sleeve 10 on the left will enter the sleeve 10 on the other side through the oil pipe 12, so that the hydraulic oil can flow freely inside the two sleeves 10, allowing the slider 8 to slide freely. When the valve structure is closed, the hydraulic oil in the sleeve 10 on one side will not be able to enter the sleeve 10 on the other side, so that the slider 8 needs to compress the hydraulic oil when sliding before it can move, which makes the slider 8 unable to slide freely under working conditions, so that the horizontal adjustment rod 3 and the square steel pipe 2 can remain relatively fixed. It is only necessary to control the valve structure to control whether the horizontal adjustment rod 3 can move freely, and the adjustment position of the horizontal adjustment rod 3 can be adjusted to any position within the adjustment stroke, and will not be limited by the position and number of the adjustment holes, making it easier to use.

[0033] The valve structure includes a plurality of blocking seats 13 fixedly mounted within the oil pipe 12, a support shaft 14 slidably mounted within the oil pipe 12, and a plurality of plugs 15 fixedly mounted on the support shaft 14, with the plugs 15 corresponding one to one with the blocking seats 13. An internally threaded rod 16 is rotatably mounted within the horizontal adjustment rod 3 and is threadedly connected to the support shaft 14. When the internally threaded rod 16 is rotated, it drives the support shaft 14 to move along the axis, that is, it drives the plurality of plugs 15 to move. By controlling the positional relationship between the plugs 15 and the blocking seats 13, the blocking condition of the oil pipe 12 can be controlled, and thus whether the horizontal adjustment rod 3 can slide.

[0034] Furthermore, the support shaft 14 passes through one side of the oil pipe 12 and extends to the outside of the oil pipe 12. The oil pipe 12 is provided with a seal (the seal is conventional and will not be described in detail here) to seal the connection with the support shaft 14. The seal prevents hydraulic oil from leaking through the oil pipe 12, thereby ensuring the tightness of the oil pipe 12.

[0035] Furthermore, a plurality of rollers 17 are rotatably mounted on both sides of the slider 8, and a groove 18 is provided in the horizontal adjustment rod 3, and the rollers 17 are located in the groove 18. By rotating the rollers 17 in the groove 18, a sliding connection between the slider 8 and the horizontal adjustment rod 3 can be achieved, and the construction site can adapt to the dusty environment.

[0036] Working principle: The square steel tube 2 is connected to the support frame through the disc buckle connector 1. The horizontal adjustment rod 3, square steel cross bar 4, and square steel vertical bar 5 are an integral protective railing. The square steel cross bar 4 and the square steel vertical bar 5 are connected by bolts, and the horizontal adjustment rod 3 and the square steel vertical bar 5 are connected by welding.

[0037] When the internal threaded rod 16 is rotated, multiple plugs 15 will be driven to move. By controlling the positional relationship between the plugs 15 and the blocking seat 13, the blocking condition of the oil pipe 12 can be controlled. When the valve mechanism is opened, when the slider 8 moves to the left, the hydraulic oil inside the sleeve 10 on the left will enter the sleeve 10 on the other side through the oil pipe 12, so that the slider 8 can slide freely. When the valve structure is closed, the hydraulic oil in the sleeve 10 on one side will not be able to enter the sleeve 10 on the other side, so that the slider 8 needs to compress the hydraulic oil when sliding before it can move, which causes the slider 8 to be unable to slide freely under working conditions, so that the horizontal adjustment rod 3 and the square steel pipe 2 can remain relatively fixed. It is only necessary to control the valve structure to control whether the horizontal adjustment rod 3 can move freely, and the adjustment position of the horizontal adjustment rod 3 can be adjusted to any position within the adjustment stroke, and will not be limited by the position and number of the adjustment holes, making it easier to use.

[0038] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
