DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1 to Figure 6As shown, an engineering guardrail that is easy to install and erect, includes a unit bridge 1 for assembling into a guardrail top, a fixing clamp 5 connecting two unit bridges 1 and a bracket 6 for controlling the height of the guardrail, the unit bridge 1 includes a unit plate 2 that constitutes a guardrail railing, a pull rope 3 that supports the unit plate 2 and a rotating shaft 4 that is convenient for installing and disassembling the guardrail, several unit bridges 1 are connected and spliced ​​into the guardrail top, and brackets 6 for supporting the guardrail are installed at both ends of the guardrail top, fixing clamps 5 are provided at the connection between the two unit bridges 1 and at the connection between the unit bridge 1 and the bracket 6, the rotating shaft 4 is rotatably set in the unit bridge 1, the pull rope 3 is wound on the rotating shaft 4, the unit plate 2 is installed on the pull rope 3 and is directly below the unit bridge 1, and the unit plates 2 can be added to the pull rope 3 in sequence.

[0026] In this scheme, a plurality of unit bridges 1 are assembled together to form the top of the guardrail, and the rotation of the rotating shaft 4 in the top of the guardrail controls the rise and fall of the pull rope 3, thereby controlling the stacking and spreading of the unit plates 2 on the pull rope 3, thereby achieving the purpose of facilitating installation and erection. When a plurality of unit plates 2 are stacked together, it is convenient to collect and transport, and when a plurality of unit plates 2 are spread out on the pull rope 3, a railing of the guardrail is formed. The bracket 6 is used to control the height of the entire guardrail. At the same time, the number of unit plates 2 is added according to the height of the bracket 6, and the number of unit bridges 1 determines the length of the guardrail according to needs.

[0027] See also Figure 1 to Figure 3 As shown, the unit panel 2 includes a bracket 21, a wire hole 22, a square joint 23 and a square interface 24. The bracket 21 is installed on the pull rope 3 and is located at the bottom of the unit panel 2. The wire hole 22 passes through the entire unit panel 2 from the upper surface of the unit panel 2. The square joint 23 is installed at one end of the unit panel 2, and the square interface 24 is installed at the other end of the unit panel 2.

[0028] Since the unit board 2 will fall to the ground due to gravity, the entire unit board 2 is supported by the pull rope 3 fixed by the bracket 21. The wire hole 22 is used to pass the pull rope 3 and the installation bracket 21. The square joint 23 and the square interface 24 are engaged with each other to facilitate the docking between the two unit boards 2.

[0029] See also Figure 1 to Figure 4 As shown, the bracket 21 includes a casing 211 , a positioning pin 212 and a thread 213 . The casing 211 surrounds the outside of the pull rope 3 and is engaged with the bracket 21 . The positioning pin 212 vertically passes through the casing 211 and the pull rope 3 . The thread 213 is arranged on the surface of the casing 211 .

[0030] The sleeve 211 is fixedly mounted on the pull rope 3 by means of the positioning pin 212, and the bracket 21 is fixed on the pull rope 3 by means of the sleeve 211. The thread 213 provided on the surface of the sleeve 211 helps to adjust the height of the unit plate 2 in a small range on the pull rope 3, thereby controlling the gap of the railing.

[0031] See also Figure 3 and Figure 4 As shown, the wire hole 22 includes a fitting ring 221 and a positioning groove 222 . The positioning groove 222 is arranged in the wire hole 22 on the lower surface of the unit board 2 . The fitting ring 221 is installed on the top of the bracket 21 and is located in the positioning groove 222 .

[0032] The sizes of the fitting ring 221 and the positioning groove 222 correspond to each other. Since sliding may occur between the bracket 21 and the unit plate 2 , the bracket 21 and the unit plate 2 are firmly connected by the engagement between the fitting ring 221 and the positioning groove 222 .

[0033] See also Figure 1 and Figure 2 As shown, the rotating shaft 4 includes a positioning frame 41, an annular joint and an annular interface 43. The positioning frame 41 is installed at the inner center of the unit bridge 1, the annular joint 42 is installed at one end of the rotating shaft 4, and the annular interface 43 is installed at the other end of the rotating shaft 4.

[0034] The positioning frame 41 is used for quickly installing and disassembling the rotating shaft 4 to facilitate the maintenance of the pull rope 3 on the rotating shaft 4. The annular joint 42 and the annular interface 43 are engaged with each other to facilitate the docking between the two unit bridges 1.

[0035] See also Figure 1 to Figure 5 As shown, the positioning frame 41 includes a ring platform 411, a buckle 412 and a screw 413. The platform is installed at the inner center of the unit bridge 1. The buckle 412 is rotatably set on the top of the positioning frame 41 and is clamped with the ring platform 411. The screw 413 passes through the buckle 412 and the ring platform 411.

[0036] The ring platform 411 and the buckle 412 are both provided with contact surfaces with the same arc as the rotating shaft 4. The two contact surfaces fix the upper and lower sides of the rotating shaft 4 and ensure that the rotation of the rotating shaft 4 will not be affected. The screw 413 is used to strengthen the connection firmness between the ring platform 411 and the buckle 412, and at the same time facilitate the opening of the positioning frame 41.

[0037] See also Figure 5 As shown, the fixing clamp 5 includes a bonding plate 51, a fixing pin 52 and a first mounting bar 53, the first mounting bar 53 is arranged at the port of the unit bridge 1, the bonding plate 51 is arranged on the fixing clamp 5 and covers the two first mounting bars 53, and the fixing pin 52 passes through the fixing clamp 5 and the bonding plate 51.

[0038] The sizes of the fixing pin 52 and the first installation strip 53 correspond to each other. The bonding plate 51 and the fixing clamp 5 respectively clamp the inner and outer sides of the first installation strip 53 and fix the two by the fixing pin 52 to ensure a firm connection between the two unit bridges 1.

[0039] See also Figure 1 to Figure 6As shown, the bracket 6 includes a baffle 61 , a cross frame 62 and a second mounting bar 63 . The baffle 61 is arranged on both sides of the bracket 6 , the cross frame 62 is installed on the top of the bracket 6 , and the second mounting bar 63 is arranged at the end of the cross frame 62 .

[0040] The baffle 61 is used to limit the two sides of the unit board 2 to prevent the unit board 2 from swaying in the wind. The cross frame 62 is used to connect the unit bridge 1 and the bracket 6. The second mounting bar 63 and the first mounting bar 53 have the same size, which facilitates the fixing clamp 5 to fix the unit bridge 1 and the bracket 6. The fixing principle is the same as the connection principle of the two unit bridges 1.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. 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.
