[0034] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] The guardrail of the present utility model is described below with reference to the accompanying drawings.

[0036] The utility model provides a guardrail, such as Figure 1 , Figure 2 and Figure 3 As shown, the guardrail includes:

[0037] The pole unit 1 comprises a first pole 11 and a second pole 12 which are arranged adjacent to each other at an interval; and

[0038] The horizontal protection fence includes a plurality of fence units 21 arranged in sequence in a net chain shape, and the fence units 21 are detachably connected via a connecting assembly 22;

[0039] Among them, the plurality of fence units 21 at least include a first horizontal bar 211 detachably mounted on the first vertical pole 11 and a second horizontal bar 212 detachably mounted on the second vertical pole 12 .

[0040] When an obstacle needs to pass through the guardrail, it is only necessary to remove the fence units 21 in the corresponding area of ​​the horizontal guard fence, so that the guardrail can form a passage for the obstacle to pass through. According to the size of the obstacle, the number of fence units 21 to be removed can be freely selected to ensure that the passage is large enough for the obstacle to pass through. After some fence units 21 are removed, the fence units 21 that have not been removed near the passage are still connected to the surrounding adjacent fence units 21. Therefore, even if the obstacle passes through the guardrail, the guardrail still has a protective function.

[0041] like Figure 1 and Figure 4 As shown, in an embodiment of the utility model, the connection method of the connecting component 22 can be a clamping method. For example, the connecting component 22 can include a first clamping plate 221 and a second clamping plate 222 that are spaced apart, and a clamping cavity is formed between the first clamping plate 221 and the second clamping plate 222. The clamping cavity is used to clamp two adjacent fence units 21 at the same time, and the first clamping plate 221 and the second clamping plate 222 are connected and fixed by a connecting rod 223.

[0042] Specifically, the fence unit 21 can be a rod frame structure, and each fence unit 21 is provided with a clamping rod portion, which can extend vertically or be bent vertically. The clamping rod portions on two adjacent fence units 21 are horizontally adjacent. When connecting, it is only necessary to clamp the two adjacent clamping rod portions with the first clamping plate 221 and the second clamping plate 222 at the same time, and then connect and press them through the connecting rod 223 to complete the installation of the connecting assembly 22. After the first clamping plate 221 and the second clamping plate 222 are clamped, the positions of the two adjacent fence units 21 can still be adjusted up and down within a certain range, thereby further facilitating the fence unit 21 to avoid obstacles. Moreover, the connection of the two adjacent fence units 21 by clamping the clamping plates can increase the firmness of the horizontal protective fence.

[0043] In the embodiment of the utility model, two adjacent fence units 21 can also be connected by connecting members such as U-shaped screws and clamps.

[0044] like Figure 1 and Figure 4As shown, in the embodiment of the utility model, the connecting rod 223 is provided with an external thread, and the connecting assembly 22 also includes a tightening nut 224 screwed on the external thread of the connecting rod 223, and the tightening nut 224 abuts against the outer side of the first clamping plate 221 or the second clamping plate 222. The connecting rod 223 can be a bolt, one end of the bolt is provided with a nut, and the tightening nut 224 is screwed on the bolt. The first clamping plate 221 and the second clamping plate 222 are clamped between the tightening nut 224 and the nut. By rotating the tightening nut 224 in the direction of the nut, the clamping force of the clamping plate on the clamping rod can be adjusted. Of course, the connecting rod 223 can also be a screw rod, and nuts can be screwed on both ends of the screw rod.

[0045] like Figure 4 As shown, in an embodiment of the utility model, the lateral end of the first clamping plate 221 can be biased toward the second clamping plate 222, and / or the lateral end of the second clamping plate 222 can be biased toward the first clamping plate 221. By setting the ends of the clamping plates toward the other, the clamping rod can be prevented from slipping out of the lateral notch of the clamping groove after the first clamping plate 221 and the second clamping plate 222 clamp the clamping rod. Of course, the clamping rod can also be locked in the clamping groove by passing a pin shaft through the lateral ends of the two clamping plates.

[0046] In the embodiment of the present invention, the connection forms between the fence units 21 may be slightly different according to the different spacings between the vertical poles. Figure 1 As shown, when the distance between the first vertical pole 11 and the second vertical pole 12 is small, a plurality of fence units 21 may only include a first horizontal bar 211 located at the head of the chain and a second horizontal bar 212 located at the tail of the chain, the first horizontal bar 211 is provided with a first clamping rod portion 211a, the second horizontal bar 212 is provided with a second clamping rod portion 212a, and the first clamping rod portion 211a and the second clamping rod portion 212a are directly connected via a connecting assembly 22.

[0047] like Figure 2 and Figure 3 As shown, when the interval between the first vertical pole 11 and the second vertical pole 12 is large, more fence units 21 are required to be combined into a chain. At this time, the fence units 21 need to include a first horizontal bar 211 located at the head of the chain, a second horizontal bar 212 located at the tail of the chain, and at least one middle horizontal bar 213 located between the first horizontal bar 211 and the second horizontal bar 212. The first horizontal bar 211 is provided with a first clamping rod portion 211a, the second horizontal bar 212 is provided with a second clamping rod portion 212a, and the middle horizontal bar 213 is provided with a third clamping rod portion 213a and a fourth clamping rod portion 213b arranged at intervals. The third clamping rod portion 213a is connected to the adjacent first clamping rod portion 211a or the fourth clamping rod portion 213b through the connecting assembly 22, and the fourth clamping rod portion 213b is connected to the adjacent second clamping rod portion 212a or the third clamping rod portion 213a through the connecting assembly 22.

[0048] It should be noted that when an obstacle needs to pass through the guardrail, the first horizontal bar 211, the second horizontal bar 212, or the middle horizontal bar 213 can be freely selected to be removed according to the position of the passage.

[0049] like Figure 1 As shown, in the embodiment of the utility model, there are many ways to achieve detachable installation between the vertical pole and the fence unit 21. Taking the detachable installation of the first horizontal bar 211 on the first vertical pole 11 as an example, the first vertical pole 11 can be provided with a first insertion hole 111 that passes through horizontally, and the first horizontal bar 211 includes a first installation rod portion 211b for plugging and cooperating with the first insertion hole 111. The first installation rod portion 211b is locked and fixed in the first insertion hole 111 by a first fastener.

[0050] Furthermore, if Figure 1 As shown, the first mounting rod 211b may be provided with an external thread, and the first fastener is a mounting nut 3 screwed on the first mounting rod 211b. The mounting nut 3 is screwed on the first mounting rod 211b, so that the first mounting rod 211b can be locked on the first insertion hole 111. Of course, a locking hole may also be provided on the first mounting rod 211b, and the first fastener may be provided as a cotter pin.

[0051] like Figure 1 As shown, in the embodiment of the utility model, the installation method of the second horizontal bar 212 can be the same as the installation method of the first horizontal bar 211. That is, the second vertical bar 12 can be provided with a second insertion hole 121 that runs through horizontally, and the second vertical bar is provided with a second installation rod portion 212b for plugging and matching with the second insertion hole 121, and the second installation rod portion 212b is locked and fixed in the second insertion hole 121 by a second fastener.

[0052] In the embodiment of the present utility model, the first horizontal bar 211 and the second horizontal bar 212 may be a U-shaped structure, or an L-shaped structure, etc., and the middle horizontal bar 213 may be a U-shaped structure.

[0053] In an embodiment of the utility model, the installation height of the first horizontal bar 211 and / or the second horizontal bar 212 is adjustable, that is, the installation of the horizontal protective fence on the vertical pole is adjustable. Among them, there are many ways to achieve adjustable installation height of the horizontal protective fence, such as the number of insertion holes on the first vertical pole 11 and the second vertical pole 12 can be set to multiple, and the multiple insertion holes are staggered up and down, and the first horizontal bar and the second horizontal bar are respectively inserted in different insertion holes to achieve the change of installation height. Alternatively, the first installation rod portion 211b is sleeved on the first vertical pole 11 and locked and fixed at different heights by threaded connectors. By adjusting the installation height of the horizontal protective fence, in some scenarios, it is possible to avoid obstacles when passing through without removing the fence unit.

[0054] In an embodiment of the utility model, the transverse protective fence can be a mesh structure composed of multiple single chains, or a single chain structure. When the transverse protective fence is a single chain structure, avoidance of obstacles can only be achieved by adjusting the installation height of the transverse protective fence or changing the shape of the fence unit 21.

[0055] In the embodiment of the present invention, when the transverse protective fence is a mesh structure, the fence units 21 adjacent to each other in the transverse direction and vertically can be connected by a connecting assembly 22 .

[0056] In the embodiment of the present utility model, when a certain fence unit 21 is damaged, it can be directly replaced with a new fence unit 21, thereby facilitating the maintenance of the guardrail.

[0057] In the embodiments of the present invention, the obstacle may be mechanical equipment. Some mechanical equipment (such as air ducts) need to pass through the guardrail and interfere with the transverse protective net fence during installation. The transverse protective net fence in the guardrail of the utility model can reserve a corresponding size of the crossing channel in advance according to the estimated shape, position and size of the obstacle during assembly, or after the mechanical equipment is installed, the net fence units can be spliced ​​in sequence according to the actual situation. The assembly method is more flexible and can better adapt to the protection scenarios of obstacles of various shapes passing through the guardrail.
