[0030] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0031] The present invention provides a safety protection device for grid installation. This device can adjust the guide rail by setting sliding parts and rollers on the grid, extending to one side so that the safety net on the suspension rail can follow the adjustment, providing an additional safety measure for construction workers. The safety protection device for grid installation will be described below.

[0032] The following combines Figures 1 to 7 to describe the structure of the safety protection device for grid installation of the present invention.

[0033] Referring to Figure 1 , the present invention provides a safety protection device for grid installation, which is arranged on the roof structure. The protection device includes: a suspension rail 7, a safety net 8, a grid body, which is connected to the roof structure, a sliding part arranged at intervals under the grid body, a suspension rail 7 sleeved on the same row of sliding parts, the suspension rail 7 can be adjusted in position on the sliding part, and by adjusting the suspension rail 7 on the sliding part, the suspension rail 7 can move to the side away from the grid, a safety net 8 tied between two adjacent suspension rails 7, the width of the safety net 8 is 1.5 times the width of the grid body, in a hanging state, and the safety net 8 can move with the suspension rail 7.

[0034] Preferably, as Figure 1 shown, by placing the grid body on the roof structure to form a roof cover, setting a sliding part under the grid body, tying a safety net 8 on the suspension rail 7, and then connecting the suspension rail 7 to the sliding part, and displacing through the guide rail on the sliding part, the suspension rail 7 drives the safety net 8 to displace, so as to realize the adjustment of the safety net 8 according to the construction progress and always provide additional protection for construction workers.

[0035] Referring to Figures 1 to 4 , in a specific embodiment of the present invention, the grid body includes an upper chord frame body connected to the roof mechanism, a lower chord frame body connected to the roof mechanism, and web members 3 connecting the upper chord frame body and the lower chord frame body.

[0036] Furthermore, as Figures 1 to 4 shown, by arranging web members 3 between the upper chord frame body and the lower chord frame body, when connecting the upper chord frame body and the lower chord frame body, it can also provide a supporting effect for them.

[0037] Referring to Figure 1 , Figure 3 , Figure 4, in a specific embodiment of the present invention, the upper chord frame body includes a plurality of upper chord bars 1 and a first bolt ball 2 connected between two adjacent upper chord bars 1. The upper chord bars 1 are connected to corresponding positions of the first bolt ball 2 to enable the first bolt ball 2 to connect the plurality of upper chord bars 1, thereby forming a frame body. The lower chord frame body includes a plurality of lower chord bars 4 and a second bolt ball 5 connected between two adjacent lower chord machines. The second bolt ball 5 connects the plurality of lower chord bars 4 to form a frame body.

[0038] Further, as Figure 1 , Figure 3 , Figure 4 shown, a plurality of upper chord bars 1 are connected together by a plurality of first bolt balls 2 to enclose and form an upper chord frame body. Then, a plurality of lower chord bars 4 are connected together by a plurality of second bolt balls 5 to enclose and form a lower chord frame body. And the web members 3 can be connected through the arrangement of the bolt balls. The web members 3 can be obliquely connected between the upper chord frame body and the lower chord frame body for support.

[0039] Referring to Figure 5 , Figure 7 , in a specific embodiment of the present invention, the sliding part includes a connecting member 6 connected to the grid frame body and rollers 61 movably installed on both sides of the connecting member 6. The hanging rail 7 includes a U-shaped plate with an upward opening, an inclined plate connected to the opening of the U-shaped plate, and a cross plate connected to the side of the inclined plate close to the connecting member 6. The cross plate is connected to the inclined plate and is arranged on the U-shaped plate to enclose a sliding space for the rollers 61 to move forward or backward. Through the sliding space, the hanging rail 7 can move on the rollers 61, thereby realizing the extension adjustment of the guide rail driving the safety net 8. The connecting member 6 includes a first connecting seat connected to the grid frame body, a second connecting seat connected to the first connecting seat, and a wheel plate connected to the second connecting seat. The wheel plate can place the rollers 61.

[0040] Further, as Figure 5 , Figure 7 shown, the connecting member 6 is connected by a second bolt ball 5, and the rollers 61 are fixed by the connecting member 6 to prevent the rollers 61 from shaking. And placing the guide rail on the rollers 61 can enable displacement adjustment of the guide rail.

[0041] Furthermore, the sliding space of the guide rail can enable the rollers 61 to roll inside it. Through the arrangement of the inclined rod and the cross bar, the upper part of the rollers 61 can be restricted, so that the rollers 61 are always in the sliding space and will not fall off.

[0042] Referring to Figure 6, in a specific embodiment of the present invention, hanging rings 71 are connected to opposite sides of the hanging rail 7 at intervals, and the safety net 8 can be tied through the hanging rings 71, so that the safety net 8 is fixed.

[0043] Further, as Figure 6 shown, by providing the hanging rings 71 on both sides of the guide rail, connection positions can be provided for the safety net 8.

[0044] Refer to Figure 6 , in a specific embodiment of the present invention, the hanging rail 7 includes first limiting members 72 arranged at intervals and second limiting members 73 arranged at intervals and away from the first limiting members 72. By moving the hanging rail 7 on the sliding part, the first limiting members 72 and the second limiting members 73 are moved to both sides of the sliding part, and then the position of the sliding part on the hanging rail 7 is restricted, so as to realize the adjustment of the extension length of the guide rail.

[0045] Further, as Figure 6 shown, through the arrangement of the first limiting members 72 and the second limiting members 73, the connecting member 6 of the sliding part can be restricted between the two, which is beneficial to fixing the position of the guide rail and facilitating the adjustment of the extension length of the guide rail according to the construction process.

[0046] Refer to Figure 6 , in a specific embodiment of the present invention, the first limiting member 72 includes at least two limiting blocks provided on the hanging rail 7 and a movable stop rod connected to one of the limiting blocks, and the stop rod can be lapped on the other limiting block.

[0047] Further, as Figure 6 shown, the connecting member 6 is driven by the roller 61 to move on the guide rail, so that the connecting member 6 pushes against the stop rod, causing the stop rod to deflect away from the other limiting block (open state), enabling the connecting member 6 to pass through. Subsequently, after the connecting member 6 passes through the stop rod, the fixed end of the stop rod is elastically connected to the limiting block and can rebound. When the stop rod is not pushed by the connecting member 6, it will return to the horizontal position and contact the other limiting block (closed state). At this time, the connecting member 6 can be blocked, and the stop rod is a one-way passing device that can only be opened by the push of the connecting member 6. After the connecting member 6 passes through the stop rod, it cannot move backward again, which can prevent the guide rail 7 from moving backward.

[0048] Refer to Figure 6 , in a specific embodiment of the present invention, the second limiting member 73 includes at least two limiting shafts provided on the hanging rail 7 and a movable hook connected to one of the limiting shafts, and the hook can be lapped on the other limiting shaft.

[0049] Further, as Figure 6As shown, by adjusting the hook on one side of the limit shaft to an upright position (open state), the connecting member 6 can pass through between the limit shafts on both sides at this time. When the guide rail is adjusted to the length required for construction, the connecting member 6 is placed between the first limiting member 72 and the second limiting member 73, and then the hook is laid down again (closed state). At this time, the connecting member 6 can be restricted between the first limiting member 72 and the second limiting member 73 to prevent the connecting member 6 from shifting.

[0050] As Figures 1 to 7 shown, the installation process of a safety protection device for grid installation according to the present invention will be described below.

[0051] First, a plurality of upper chord members are connected by a plurality of first bolt balls to form an upper chord frame body, and then a plurality of lower chord members are connected by a plurality of second bolt balls to form a lower chord frame body. And the web members are connected through the arrangement of the bolt balls, and the web members are used to connect the upper chord frame body and the lower chord frame body to form a grid. Then, the connecting member is fixed on the second bolt ball on the lower chord frame body by bolts, and the guide rail is sleeved on the roller, and the displacement of the guide rail is adjusted according to the construction requirements. When the guide rail is adjusted to the length required for construction, the connecting member is placed between the first limiting member and the second limiting member, and the first limiting member and the second limiting member are used to restrict the connecting member to prevent the connecting member from being adjusted back and forth.

[0052] The present invention has been described in detail above in conjunction with the embodiments with reference to the drawings.
