For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] Figure 1 The front view of the horizontal net support device provided in an embodiment of the present invention is shown, consisting of... Figure 1 As can be seen, the horizontal safety net support device provided in the embodiment of this utility model includes a base 3 fixed at the edge of the floor slab 1 (the floor slab includes a floor bottom slab 1 and a floor top slab 2), and the base 3 serves as the initial support body for the entire horizontal safety net support device; wherein, an inclined support rod extending to the outer side of the floor bottom slab 1 (i.e., the outer side of the floor slab, i.e., the outer edge of the floor) is rotatably connected to one side of the base 3, and the inclined support rod is inclined upward. The safety net to be installed is hung on the inclined support rod, thereby realizing the erection of the safety net; since the inclined support rod is rotatably connected to the side of the base 3, in order to fix the position of the inclined support rod, a traction component is needed to be pulled on the inclined support rod to pull and suspend the inclined support rod. When the inclined support rod rotates to a preset inclination angle, the inclined support rod is fixed at the preset inclination angle by the traction component, thereby supporting the safety net.

[0030] Specifically, in order to fix the base 3 at the edge of the floor slab, a vertically installed vertical support rod can be connected to the top of the base 3. The lower end of the vertical support rod is fixed to the base 3, and a top support 4 is fixed to the upper end of the vertical support rod. The height of the vertical support rod is adjustable. By adjusting the height of the vertical support rod, the top support 4 is pressed against the floor slab 2, thereby fixing the position of the base 3.

[0031] Furthermore, to achieve height adjustment of the vertical support rod, the vertical support rod may include a first main rod 5 and a second main rod 6; wherein, the lower end of the first main rod 5 is fixedly connected to the top of the base 3, the upper end of the first main rod 5 is connected to the lower end of the second main rod 6 through a positive and negative threaded connector 7, and the upper end of the second main rod 6 is fixedly connected to the top support 4, and the height of the entire vertical support rod is adjusted by rotating the positive and negative threaded connector 7.

[0032] Furthermore, Figure 2 This diagram shows a partially enlarged cross-sectional view of the positive and negative threaded connector 7 provided in an embodiment of the present invention, consisting of... Figure 2 It is understood that, in order to achieve height adjustment of the vertical support rod by the positive and negative threaded connector 7, the positive and negative threaded connector 7 may include a turntable 71, a first screw 73 fixed at the bottom of the turntable 71, and a second screw 72 fixed at the top of the turntable; a first screw hole 75 adapted to the first screw 73 is opened at the upper part of the first main rod 5, and the first screw 73 is connected in the first screw hole 75; a second screw hole 74 adapted to the second screw 72 is opened at the lower part of the second main rod 6, and the second screw 72 is connected in the second screw hole 74. It should be noted that the thread direction of the first screw 73 needs to be opposite to that of the second screw 72 (at this time, the thread direction of the first screw hole is the same as that of the second screw hole). With this setting, the second screw 72 can be turned into the second screw hole 74 while the first screw 73 is turned into the first screw hole 75; and the second screw 72 can be turned out of the second screw hole 74 while the first screw 73 is turned out of the first screw hole 75, thereby realizing the height adjustment of the entire vertical support rod.

[0033] In one specific embodiment of this utility model, to achieve the traction of the inclined support rod by the traction assembly, the traction assembly may include a first winch 12 mounted on the base 3, a first steel wire rope 11 wound on the first winch 12, a first fixed pulley 15 disposed at the middle of the vertical support rod, and a first fixing ring 17 fixed at the middle of the inclined support rod; wherein, the first steel wire rope 11 passes around the first fixed pulley 15 and is connected to the first fixing ring 17. In actual operation, the tilt angle of the inclined support rod is adjusted by the first winch 12 winding and unwinding the first steel wire rope 11.

[0034] In addition, the traction assembly may also include a second winch 13 mounted on the base 3, with a second wire rope 10 wound on the second winch 13. A second fixed pulley 14 is provided on the upper part of the vertical support member, and a second fixing ring 16 is fixed at the end of the inclined support member away from the base 3. The second wire rope 10 passes around the second fixed pulley 14 and is connected to the second fixing ring 16. By setting a second set of wire ropes, the traction stability of the inclined support member can be further improved. It should be noted that, in actual operation, the two sets of wire ropes need to be coordinated in winding and unwinding to ensure that both sets of wire ropes are taut and that the tensile stress of the two sets of wire ropes is basically the same.

[0035] In addition, to further ensure that the tensile stress on the two sets of wire ropes is basically the same and to ensure the stability of the entire traction assembly, a first U-shaped retaining ring 20 can be fixed on the first wire rope 11 and a second U-shaped retaining ring 21 can be fixed on the second wire rope 10. In actual operation, when the two sets of wire ropes are evenly stressed, the first U-shaped retaining ring 20 and the second U-shaped retaining ring 21 are connected by a limiting wire rope 19.

[0036] In another specific embodiment of the present invention, the inclined support rod may include a first auxiliary rod 8 and a second auxiliary rod 9; wherein the lower end of the first auxiliary rod 8 is rotatably connected to the side of the base 3 via a movable shaft 18, and the second auxiliary rod 9 is connected to the end of the first auxiliary rod 8 away from the base 3.

[0037] It should be noted that the horizontal safety net support device provided by this utility model is used in pairs. Each pair (two horizontal safety net support devices) is installed at different positions along the edge of the floor slab and has two inclined support rods. A safety net is hung between the two inclined support rods (the two inclined support rods are connected to both sides of a safety net). To further illustrate the construction principle of the horizontal safety net support device provided by this utility model, the usage process of the horizontal safety net support device provided by this utility model is described in detail below:

[0038] First, in the interior of a certain floor, the second auxiliary pole 9 is pulled out from the first auxiliary pole 8, and the first auxiliary pole 8 and the second auxiliary pole 9 are fixed with the pin 22. Then, the first main pole 5 and the main pole are initially connected through the positive and negative threaded connector 7. Then, the two sides of the safety net are respectively hung on a set (two) of the inclined support rods of the horizontal net support device provided by this utility model, so that the first wire rope 11 and the second wire rope 10 are both pulled out from the corresponding winches, respectively passing around the first fixed pulley 15 and the second fixed pulley 14, and respectively connected and fixed to the first fixed ring 17 and the second fixed ring 16. Then, push the two sets of horizontal net support devices to different positions on the edge of the floor slab, and ensure that the top support 4 of the two horizontal net support devices is close to the top slab 2 and the base 3 is close to the bottom slab 1 by rotating the turntable; finally, adjust the position of the first auxiliary rod 8 and the second auxiliary rod 9 by winding and unwinding the steel wire ropes of the two winches. After the two steel wire ropes are evenly stressed, fix the first steel wire rope 11 and the second steel wire rope 10 with the limiting steel wire rope 19; when this device is removed, rotate the turntable in the opposite direction to separate the top support 4 from the top of the floor, and then pull the entire horizontal net support device back into the floor.

[0039] As can be seen from the above specific embodiments, the horizontal net support device provided by this utility model has a simple structure, is easy to standardize and produce, has high reliability and high safety; and since the entire operation is basically completed indoors, the requirements for installation personnel are not high, thus ensuring the safety of operators to the greatest extent.
