[0002] During the construction of municipal roads and bridges, it is generally necessary to use guardrails to shield the roads and construction sites to enhance personal safety and the protection and safeguarding of equipment and facilities. At the same time, guardrails can also be used to mark the driving range of vehicles under construction, divide traffic directions, and warn of traffic safety. Although the existing guardrails can play a protective role, the two adjacent sets of guardrails are not connected, resulting in only multiple sets of separate individuals between the installed guardrails.

[0003] In order to solve the above problems, a Chinese utility model patent (publication number: CN218176868U) discloses a guardrail for bridge construction, including a frame, a partition rod is installed on the inner wall of the frame, a connecting mechanism is arranged above the frame, and the connecting mechanism includes a chamber, a chamber is opened on the right side of the top end of the frame, and an insertion rod is inserted into the chamber, a pull plate is fixedly connected to the top of the insertion rod, and a fixing rod is fixedly connected to the left side of the bottom end of the pull plate, a first socket for inserting the fixing rod is opened inside the frame, and a second socket is opened on the left side of the frame.

[0004] The above scheme connects two adjacent sets of frames by setting a connection mechanism, so that multiple sets of frames form a whole, which improves the protection effect. However, since the guardrail is fixed, the horizontal bar and the vertical bar of the guardrail are fixedly connected. After the safety guardrail is used, it occupies a large storage space and is not easy to store. In addition, since the length of each railing is fixed, it is not easy to grasp the specific length required by the site by splicing the railing to increase the length, and the length adjustment adaptability is low.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a high-safety bridge construction guardrail, including:

[0025] Base 1;

[0026] A support frame 2, wherein two support frames 2 are located above the base 1;

[0027] The storage frame 3 is arranged on the top of the base 1 and between the two support frames 2. Both ends of the storage frame 3 are telescopically connected with telescopic parts, and the two telescopic parts are respectively connected to the two support frames 2 accordingly.

[0028] In the prior art, since the guardrail is fixed, the horizontal bar and the vertical bar of the guardrail are fixedly connected, and after the safety guardrail is used, it takes up a large storage space and is not easy to store. In addition, since the length of each railing is fixed, it is not easy to grasp the specific length required by the site by splicing the railing to increase the length, and the length adjustment adaptability is low.

[0029] In order to solve the above problems, telescopic parts are arranged on both sides of the storage frame 3 in this embodiment. On the one hand, the telescopic parts can be extended to adjust the total length of the guardrail, and on the other hand, the telescopic parts can be retracted to facilitate the operator to transport and store.

[0030] Specifically, the detailed working process of this embodiment is as follows:

[0031] When adjusting the length, the base 1 is used to support the storage frame 3 to keep it stable, and then the support frames 2 on both sides of the storage frame 3 are manually pulled, and the support frames 2 drive the telescopic parts to extend out of the storage frame 3 to extend the total length of the guardrail.

[0032] During storage and transportation, the support frames 2 on both sides of the storage frame 3 are manually pushed, and the telescopic parts are retracted to enter the storage frame 3 .

[0033] In order to ensure that the guardrail can be stably supported on the ground after being extended; further, a telescopic block 17 is slidably connected to the bottom of the support frame 2 and a hydraulic rod 18 is arranged between the support frame 2 and the telescopic block 17; a suction cup 19 is arranged at the bottom of the telescopic block 17.

[0034] In this embodiment, the suction cup 19 can have good contact with the ground to ensure stable support of the support frame 2. In addition, under normal conditions, when the base 1 is in contact with the ground, the suction cup 19 is at a distance from the ground; therefore, the suction cup 19 will not affect the movement of the moving wheel 10.

[0035] In this embodiment, a driving groove is opened at the bottom of the support frame 2, and the telescopic block 17 is slidably arranged in the driving groove. Then, the hydraulic rod 18 is started to slide the telescopic block 17 downward and finally drive the suction cup 19 to contact the ground for stable support.

[0036] When the suction cup 19 is not in use, it is unfixed from the ground, and then the hydraulic rod 18 is started to drive the telescopic block 17 and the suction cup 19 to move upward, and finally the suction cup 19 is separated from the ground.

[0037] like Figure 2 As shown, further, the two telescopic parts each include:

[0038] A fixing plate 4, wherein the fixing plate 4 is disposed in the storage frame 3 and is provided with a first sliding hole 6;

[0039] A movable plate 5, wherein a second sliding hole 7 is formed on the movable plate 5 and is connected to one of the support frames 2;

[0040] A scissor-type telescopic part 8, wherein a plurality of scissor-type telescopic parts 8 are provided, and the plurality of scissor-type telescopic parts 8 are located between the fixed plate 4 and the movable plate 5, and two adjacent scissor-type telescopic parts 8 are hinged;

[0041] Each scissor-type telescopic part 8 includes two cross-connected and hinged support rods 9, and the free end of one of the support rods 9 on the scissor-type telescopic parts at both ends is slidably connected to the first sliding hole 6 and the second sliding hole 7 respectively.

[0042] Specifically, the opening angle of the two supporting rods 9 of the scissor telescopic part 8 becomes larger to achieve extension, that is, the telescopic member extends out of the storage frame 3; the opening angle of the two guard bars becomes smaller to achieve contraction, that is, the telescopic member is retracted into the storage frame 3.

[0043] The two support frames 2 are pulled separately and moved away from the storage frame 3, and the two support frames 2 drive the corresponding movable plates 5 to move. The scissors-type telescopic part 8 is extended under the action of the pulling force, and the opening angle of the two support rods 9 in each scissors-type telescopic part 8 becomes larger to extend the total length of the guardrail, which is convenient for adjusting the length of the guardrail.

[0044] When retracting, pull the two support frames 2 and move them toward the storage frame 3. The two support frames 2 drive the corresponding movable plates 5 to move, and the scissors-type telescopic parts 8 extend under the action of the pulling force. The opening angle of the two support rods 9 in each scissors-type telescopic part 8 becomes smaller so that they can be retracted into the storage frame 3 for easy transportation by the operator.

[0045] Further, a warning sign 20 is provided on the top of the storage frame 3. By providing the warning sign 20, the passing lane is warned to reduce the risk of safety accidents.

[0046] like Figure 1 and Figure 2 As shown, in order to facilitate the guardrail, the utility model also proposes another embodiment. The main difference between this embodiment and the above embodiment is that the base 1 is connected to a moving wheel 10, and a moving component is arranged between the base 1 and the moving wheel 10.

[0047] In this embodiment, a moving wheel 10 is provided to facilitate the movement and transfer of the guardrail; in addition, a moving assembly is provided to control the moving wheel 10 to ensure the movement or fixation of the guardrail. Specifically, when the moving wheel 10 slides downward and is located below the base 1, the guardrail is in a moving state; when the moving wheel 10 slides upward and is located above the base 1, the guardrail is in a fixed state.

[0048] Further, if Figure 2 and Figure 3 As shown, the base 1 is provided with a moving slot 11 for placing a moving component, and the moving component includes:

[0049] A rotating rod 12, wherein the rotating rod 12 is arranged in the movable groove 11 for transverse rotation, and one end of the rotating rod 12 is connected to a knob 21 located outside the movable groove 11;

[0050] A screw rod 13, which is vertically rotatably arranged in the movable groove 11 and is transmission-connected to the rotating rod 12;

[0051] The moving block 14 slides in the moving groove 11 and is threadedly connected to the screw rod 13 , and the bottom of the moving block 14 is connected to the moving wheel 10 .

[0052] Specifically, the working process of the mobile component in this embodiment is as follows:

[0053] When fixed, rotate the knob 21, and in this embodiment, the transmission form of the screw rod 13 and the rotating rod 12 is gear transmission; specifically, the screw rod 13 is provided with an active bevel gear 15, and the rotating rod 12 is provided with a driven bevel gear 16 meshing with the active bevel gear 15; therefore, under the meshing of the active bevel gear 15 and the driven bevel gear 16, the rotating rod 12 rotates to drive the screw rod 13 to rotate, the screw rod 13 is threadedly connected to the moving block 14, and the moving block 14 slides in the moving groove 11 to limit the moving block 14 to a certain extent; thereby, the screw rod 13 drives the moving block 14 to slide upward in the moving groove 11 so that the moving wheel 10 is located above the base 1.

[0054] When moving, the knob 21 is rotated in the opposite direction, the rotating rod 12 rotates in the opposite direction and drives the screw rod 13 to rotate in the opposite direction. Under the threaded connection with the moving block 14, the moving block 14 moves downward and the moving wheel 10 moves to the bottom of the base 1 and contacts the ground. At this time, the guardrail is supported and is in a sliding state.

[0055] The specific working process of the utility model is:

[0056] The guardrail is moved to a suitable position by using the moving wheels 10, and the base 1 is used to support the storage frame 3 to maintain stability.

[0057] When fixed, rotate the knob 21, and in this embodiment, the transmission form of the screw rod 13 and the rotating rod 12 is gear transmission; specifically, the screw rod 13 is provided with an active bevel gear 15, and the rotating rod 12 is provided with a driven bevel gear 16 meshing with the active bevel gear 15; therefore, under the meshing of the active bevel gear 15 and the driven bevel gear 16, the rotating rod 12 rotates to drive the screw rod 13 to rotate, the screw rod 13 is threadedly connected to the moving block 14, and the moving block 14 slides in the moving groove 11 to limit the moving block 14 to a certain extent; thereby, the screw rod 13 drives the moving block 14 to slide upward in the moving groove 11 so that the moving wheel 10 is located above the base 1.

[0058] Afterwards, the two support frames 2 drive the corresponding movable plates 5 to move, and the scissor-type telescopic parts 8 extend under the action of the pulling force. The opening angle of the two supporting rods 9 in each scissor-type telescopic part 8 becomes larger to extend the total length of the guardrail, which is convenient for adjusting the length of the guardrail.

[0059] Finally, the hydraulic rod 18 is started to slide the telescopic block 17 downwards and finally drive the suction cup 19 to contact the ground for stable support.

[0060] When the suction cup 19 is not in use, it is unfixed from the ground, and then the hydraulic rod 18 is started to drive the telescopic block 17 and the suction cup 19 to move upward, and finally the suction cup 19 is separated from the ground.

[0061] When the telescopic part is retracted for transportation, the two support frames 2 are pulled and moved toward the direction close to the storage frame 3. The two support frames 2 drive the corresponding movable plates 5 to move, and the scissors-type telescopic part 8 is extended under the action of the pulling force. The opening angle of the two support rods 9 in each scissors-type telescopic part 8 becomes smaller so that the two rods 9 are retracted into the storage frame 3 for easy transportation by the operator.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
