The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] See also Figure 1-5 , a construction engineering safety fence, including a base 1, two support rods 2 are fixedly arranged on the base 1, a horizontal plate 3 is fixedly connected between the two support rods 2, two limit frames 4 are fixedly arranged between the horizontal plate 3 and the base 1, a moving chamber 5 is arranged in one of the support rods 2, a bidirectional screw 6 is rotatably arranged in the moving chamber 5, the upper end of the bidirectional screw 6 passes through the support rod 2 and is fixedly connected with a turning handle 7, two L-shaped fixing blocks 8 are threadedly connected on the bidirectional screw 6, a moving groove 9 matched with the fixing block 8 is arranged on one side of the support rod 2, and two fixing grooves 10 matched with the fixing block 8 are arranged on one side of the other support rod 2;

[0031] A lifting seat 11 is movably connected in each of the two limit frames 4 , and a plurality of lifting rods 12 are fixedly provided on the lifting seat 11 . The upper ends of the plurality of lifting rods 12 pass through the transverse plate 3 and are fixedly connected to a lifting plate 13 .

[0032] In this embodiment, when it is necessary to connect and install two adjacent safety fences, the two safety fences are brought close together, and the two fixing blocks 8 of one of the safety fences are moved into the two fixing grooves 10 of the other safety fence. The handle 7 is turned, and the handle 7 drives the bidirectional screw 6 to rotate. The bidirectional screw 6 is provided with two threaded areas in opposite directions, so that the two fixing blocks 8 move along the moving groove 9 in the direction of separation, and the fixing blocks 8 are stuck in the two fixing grooves 10, so that the two safety fences are connected and fixed.

[0033] More specifically, by turning the handle 7, the two fixing blocks 8 are stuck in the fixing grooves 10 of the adjacent safety fences, thereby connecting and fixing the two adjacent safety fences. When the lifting seat 11 moves upward, the lifting seat 11 drives the plurality of lifting rods 12 to move upward, and the lifting rods 12 drive the cross plate 3 to move upward, thereby adjusting the height of the entire safety fence.

[0034] See also Figure 1-5As an implementation method for moving the lifting seat 11: two first lead screws 14 are rotatably provided between the cross plate 3 and the base 1, and the two first lead screws 14 are threadedly connected to the lifting seat 11. A driving chamber 15 is provided in the base 1, and the lower end of each first lead screw 14 extends into the driving chamber 15 and is fixedly connected to a driven bevel gear 16. A rotating rod 17 is rotatably provided in the driving chamber 15, and three driving bevel gears 18 are provided on the rotating rod 17, wherein two of the driving bevel gears 18 are respectively meshed and connected with two driven bevel gears 16, and a handle 19 is rotatably provided on one side of the base 1, and one end of the handle 19 extends into the driving chamber 15 and is fixedly connected with a rotating bevel gear 20, and the rotating bevel gear 20 is meshed and connected with one of the driving bevel gears 18.

[0035] Specifically, the handle 19 is turned, and the handle 19 drives the rotating bevel gear 20 to rotate, and the rotating bevel gear 20 drives one of the driving bevel gears 18 to rotate, and the driving bevel gear 18 drives the rotating rod 17 to rotate, so that the rotating rod 17 drives the other two driving bevel gears 18 to rotate, and the driving bevel gear 18 drives the driven bevel gear 16 to rotate, and the driven bevel gear 16 drives the first lead screw 14 to rotate. Since the first lead screw 14 is threadedly connected to the lifting seat 11, the lifting seat 11 moves.

[0036] See also Figure 1-5 As an implementation method for moving the support seat 25: sleeves 21 are fixedly provided on both sides of each support rod 2, a second screw 22 is movably provided in the sleeve 21, two limit blocks 23 are fixedly provided on the second screw 22, two limit grooves 24 matching with the limit blocks 23 are provided on the sleeve 21, one end of the second screw 22 is fixedly connected to the support seat 25, the second screw 22 is threadedly connected to a rotating ring 26, and the rotating ring 26 is rotatably connected to the sleeve 21.

[0037] Specifically, the four rotating rings 26 are rotated in sequence so that the rotating rings 26 rotate around the rotating connection with the sleeve 21. Since the rotating rings 26 are threadedly connected to the second lead screw 22, and the limit block 23 and the limit groove 24 limit the second lead screw 22, the rotating ring 26 rotates and drives the second lead screw 22 to move. The second lead screw 22 drives the limit block 23 to move along the limit groove 24. At the same time, the second lead screw 22 drives the support seat 25 to move, so that the support seat 25 contacts the ground, thereby providing anti-dumping support for the entire safety fence.

[0038] In summary, when the overall equipment is in use:

[0039] When it is necessary to install and connect two adjacent safety fences, the two safety fences are brought close together, and the two fixing blocks 8 of one of the safety fences are moved into the two fixing grooves 10 of the other safety fence. The handle 7 is turned, and the handle 7 drives the bidirectional screw 6 to rotate. The bidirectional screw 6 is provided with two threaded areas in opposite directions, so that the two fixing blocks 8 move along the moving groove 9 in the direction of separation, and the fixing blocks 8 are stuck in the two fixing grooves 10, so that the two safety fences are connected and fixed. When it is necessary to disassemble them, the opposite operation can be used.

[0040] When the height of the entire safety fence needs to be adjusted, the handle 19 is turned, and the handle 19 drives the rotating bevel gear 20 to rotate, and the rotating bevel gear 20 drives one of the driving bevel gears 18 to rotate, and the driving bevel gear 18 drives the rotating rod 17 to rotate, so that the rotating rod 17 drives the other two driving bevel gears 18 to rotate, and the driving bevel gear 18 drives the driven bevel gear 16 to rotate, and the driven bevel gear 16 drives the first lead screw 14 to rotate. Since the first lead screw 14 is threadedly connected to the lifting seat 11, the lifting seat 11 moves, and the lifting seat 11 drives multiple lifting rods 12 to move upward, and the lifting rods 12 drive the cross plate 3 to move upward, thereby adjusting the height of the entire safety fence.

[0041] When the entire safety fence needs to be supported to prevent tipping, the four rotating rings 26 are rotated in sequence so that the rotating rings 26 rotate around the rotating connection with the sleeve 21. Since the rotating rings 26 are threadedly connected to the second lead screw 22, and the limit block 23 and the limit groove 24 limit the second lead screw 22, the rotating ring 26 rotates and drives the second lead screw 22 to move. The second lead screw 22 drives the limit block 23 to move along the limit groove 24. At the same time, the second lead screw 22 drives the support seat 25 to move, so that the support seat 25 contacts the ground, thereby providing anti-tip support for the entire safety fence.

[0042] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
