Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] like Figure 1 As shown, a road construction safety barrier includes two supporting main poles 1, a barrier component 2, and a placement component 3. The barrier component 2 is respectively fitted onto the upper part of the supporting main pole 1 at both ends, and the placement component 3 is detachably connected to the lower part of the supporting main pole 1.

[0028] like Figure 2 and Figure 4 As shown, the isolation assembly 2 includes a connecting top frame pair, multiple telescopic rods 202, two connecting base plates 203, a locking rod 204, a locking hole 205, a connector 206, and a connecting bolt 207. The connecting top frame pair includes a pair of connecting top frames 201. One end of each connecting top frame 201 has a fixed ring portion. One connecting top frame 201 has a connector 206 fixedly installed at the other end, and the other connecting top frame 201 also has a connector 206 fixedly installed at the other end. The two connectors 206 are female-female connectors that can be spliced ​​together. The ring portion of the connecting top frame 201 is used to fit onto the upper part of the supporting main rod 1, thereby fixing it to the supporting main rod. The female-female connectors 206 of the two connecting top frames 201 can be interlocked to form a shaft hole, and are connected by a connecting bolt 207. The connecting bolt 207 fits into the shaft hole of the connector 206, allowing the two connecting top frames 201 to rotate relative to each other.

[0029] And the top of the support main rod 1 is fixedly connected with a warning light 6, the top of the connecting top frame 201 is fixedly connected with a solar panel 7 for providing power for the warning light 6 when needed, the warning light 6 and the solar panel 7 are electrically connected through a switch button, and the switch button is arranged on the connecting top frame 201 (not shown in the figure). The solar panel can convert solar energy into electrical energy and store it in the power source arranged in the power source connecting top frame 201. When the external environment is relatively dark, the staff can use the switch button to turn on the warning light 6 connected with the power source.

[0030] The telescopic boom 202 includes an outer sleeve and multiple inner tubes, which can flexibly extend and retract in length. The minimum length of the telescopic boom is used when it is stored to minimize the use of the road engineering isolation fence, the maximum length of the telescopic boom is used to drop and deploy the telescopic boom 202, cooperate with the connecting bottom plate 203 to form an isolation net between the two support main rods, and the maximum length of the telescopic boom can approach the upper end of the placing assembly 3. One end of the telescopic boom 202 is fixedly arranged at the bottom of the connecting top frame 201, and the other end is fixedly connected to the upper surface of the connecting bottom plate 203. Two connecting bottom plates 203 are arranged in parallel, and the opposite side walls between the two connecting bottom plates are a certain distance apart, so that when the two connecting top frames 201 are rotated, they will not be affected by the connecting bottom plates.

[0031] Moreover, a locking rod 204 is rotatably arranged on the upper surface of one of the connecting bottom plates 203, and a part of the inside of the locking rod 204 is provided with threads, so as to be able to be connected with the connecting bottom plate 203 through bolt threads. The bottom of the connecting top frame 201 is provided with a locking hole 205, the position of the locking hole 205 corresponds to the position of the locking rod 204, and the inside of the locking hole 205 is provided with a clamping block. When the end of the locking rod is inserted into the locking hole and the locking rod is rotated, the clamping block in the inside of the locking rod is inserted into the groove on the outer surface of the end of the locking rod, so as to lock the end of the locking rod. When the barrier is not needed, the locking rod 204 is inserted into the locking hole 205 during the day, at which time the connecting bottom plate 203 is close to the connecting top frame 201; when needed, the locking rod is rotated to make the end of the locking rod come out of the locking hole 205, each telescopic boom 202 is affected by gravity to drop and extend its length to the maximum, so that the connecting bottom plate 203 is away from the connecting top frame 201 and approaches the upper end of the placing assembly 3, so as to realize that the support main rod 1 and the connecting top frame 201 form a barrier on one side. Since the two connecting top frames are formed as a whole through the connecting piece and the connecting bolt, only one locking rod 204 is needed to realize the dropping and recovery of the telescopic boom 202.

[0032] As Figure 3As shown, the placing assembly 3 includes a counterweight base 301, an extension block 302, a flip plate 303 and a non-slip pad 304. The counterweight base 301 is a sleeve structure rectangular block with a hollow part, the inner wall profile of which is adapted to the outer wall of the support main rod 1, so as to be able to be sleeved at the bottom of the support main rod 1 and fixedly connected with the support main rod. Four extension blocks 302 are fixedly connected to the bottom of the four side walls of the counterweight base 301, a damping bearing is arranged in the extension block 302, one end of the flip plate 303 is hingedly connected to the inside of the extension block 302 through the damping bearing and can rotate relative to the extension block, the bottom of the flip plate 303 is fixedly connected with the non-slip pad 304, and the upper surface of the flip plate 303 is provided with a clamping block 5. A clamping groove 4 is formed in each side wall of the counterweight base 301, the size and position of the clamping groove 4 correspond to the clamping block, so that the clamping block can be clamped with the clamping groove. When placing the guardrail, open the flip plate 303 to make the clamping block 5 disengage from the clamping groove 4, and it can be turned back to adhere to the counterweight base 301 when not in use.

[0033] The installation and use method of the road engineering isolation guardrail is as follows:

[0034] First, install the placing assembly 3 at the bottom of the support main rod 1;

[0035] Then, sleeve the connecting top frame 201 on the isolation assembly 2 on the support main rod and fix it, splice the connecting top frames 201 on both sides by using the connecting bolt 207 and the connecting piece 206, so as to install the two support main rods 1 and the isolation assembly 2 together; then rotate the locking rod 204 to make the telescopic hanging rod 202 fall and expand, and cooperate with the connecting bottom plate 203 to form an isolation net between the two support main rods.

[0036] When placing the guardrail, open the two flip plates 303 which are perpendicular to the formed isolation net to make the clamping block 5 disengage from the clamping groove 4, so that the flip plate is turned down from the side wall of the counterweight base 301, increasing the contact area of the counterweight base 301 with the ground, and further improving the stability in cooperation with the non-slip pad 304. According to the actual situation, all four flip plates on each placing assembly can also be opened, so as to quickly complete the installation of the guardrail.

[0037] When needed, the switch button can also be opened to turn on the warning light 6.

[0038] When the isolation guardrail is not needed, the connecting bottom plate 203 is lifted up to make the telescopic hanging rod 202 retract, and the locking rod 204 reaches the locking hole 205, then the locking rod is rotated to lock its position, so as to reduce its volume, and then the connecting bolt 207 is disassembled to separate the two connecting top frames 201, so as to easily complete the disassembly.
