Description

Technical Field

[0001] This utility model relates to the field of road traffic facilities technology, and in particular to a traffic cone for road and bridge construction. Background Technology

[0002] Traditional traffic cones are mostly one-piece structures, requiring replacement of the entire cone if any part is damaged. During construction, traffic cones are exposed to harsh environments such as direct sunlight and weathering, causing the warning coating on the cone's surface to fade and wear. The base, due to frequent contact with the ground, is prone to breakage and wear of the gripping teeth, resulting in high replacement costs and significant resource waste. Furthermore, the installation and dismantling of traditional traffic cones are cumbersome, requiring considerable time and effort from construction personnel, making them unsuitable for adapting to changing construction areas and the need for frequent adjustments to cone placement. This also presents numerous challenges to safety protection in construction areas. Ordinary traffic cones rely solely on their warning colors, offering limited effectiveness. In complex road conditions or inclement weather, they are insufficient to attract the attention of passing vehicles and pedestrians. Moreover, a single traffic cone cannot form an effective barrier system, failing to effectively warn specific areas. Therefore, we have introduced a new type of traffic cone for road and bridge construction. Utility Model Content

[0003] The main purpose of this utility model is to provide a traffic cone for road and bridge construction, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A traffic cone for road and bridge construction includes a base, with several gripping teeth at the lower end of the base, a positioning groove at the middle of the upper end of the base, a positioning block inside the positioning groove, limit holes at the middle of the left and right ends of the positioning block, a support column at the middle of the upper end of the positioning block, an alarm on the right side of the outer surface of the support column, a traffic cone body at the upper end of the support column, a blocking device movably mounted at the upper end of the traffic cone body, a circular groove at the upper end of the base, an annular counterweight inside the circular groove, a cavity groove inside the base, and a detachable mechanism inside the cavity groove.

[0006] Preferably, the detachable mechanism includes a bidirectional lead screw, a rotating handle is fixedly installed at the right end of the bidirectional lead screw, a driving block is provided on the left and right sides of the outer surface of the bidirectional lead screw, a limit post is provided on the facing surfaces of the two driving blocks, and a through hole is provided in the middle of the inner left wall and the middle of the inner right wall of the positioning groove.

[0007] Preferably, the cavity groove is interconnected with the interior of the positioning groove through a through hole, and the position of the limiting post corresponds to the position of the through hole.

[0008] Preferably, the limiting post is movably engaged inside the limiting hole.

[0009] Preferably, the left side of the outer surface of the bidirectional lead screw is rotatably connected to the inner right wall of the cavity groove via a bearing.

[0010] Preferably, the blocking device includes a mounting rod, the upper end of which is provided with a handle, the lower end of which is fixedly mounted with a screw, the outer surface of which is movably sleeved with a first mounting sleeve, the right end of which is fixedly mounted with a warning tape, and the right end of which is provided with a second mounting sleeve.

[0011] Preferably, the mounting rod is threaded onto the upper middle part of the traffic cone body via a screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the cooperation of positioning blocks, positioning slots and detachable mechanisms, during assembly, the operator only needs to turn the handle to use the two-way screw to drive the block, so that the limit post can be quickly inserted into the limit hole, completing the installation of the traffic cone body and the base; during disassembly, simply turn the handle in the opposite direction, which greatly facilitates the individual replacement of the traffic cone body, reduces unnecessary expenses, avoids the waste of resources caused by discarding undamaged parts, and fully improves the efficiency of resource utilization.

[0014] 2. Through the synergistic action of the gripping teeth and the ring counterweight, the gripping teeth penetrate the ground to enhance friction, while the ring counterweight lowers the center of gravity, improving stability during use. The blocking device can be connected to the traffic cone body via the mounting rod, and pulling the warning tape can expand the blocking range. Combined with the audible and visual warning signals emitted by the siren, it provides multi-dimensional visual and auditory alerts to passing vehicles and pedestrians, forming a comprehensive and multi-layered warning and blocking system that greatly improves the safety of the construction area and effectively reduces the probability of accidents.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A traffic cone for road and bridge construction includes a base 1, with several gripping teeth 2 at the lower end of the base 1, a positioning groove 3 at the middle of the upper end of the base 1, a positioning block 4 inside the positioning groove 3, limit holes 5 at the middle of the left and right ends of the positioning block 4, a support column 6 at the middle of the upper end of the positioning block 4, an alarm 7 on the right side of the outer surface of the support column 6, a traffic cone body 8 at the upper end of the support column 6, a blocking device 9 movably installed at the upper end of the traffic cone body 8, a circular groove 10 at the upper end of the base 1, an annular counterweight 11 inside the circular groove 10, a cavity groove 12 inside the base 1, and a detachable mechanism 13 inside the cavity groove 12.

[0025] In this embodiment, the detachable mechanism 13 includes a bidirectional lead screw 130, a rotating handle 131 fixedly installed at the right end of the bidirectional lead screw 130, a driving block 132 provided on the left and right sides of the outer surface of the bidirectional lead screw 130, a limiting post 133 provided on the facing surfaces of the two driving blocks 132, and a through hole 134 provided in the middle of the left and right inner walls of the positioning groove 3; the cavity groove 12 is interconnected with the interior of the positioning groove 3 through the through hole 134, and the limiting post 133 is positioned corresponding to the through hole 134; the limiting post 133 is movably engaged inside the limiting hole 5; the left side of the outer surface of the bidirectional lead screw 130 is rotatably connected to the inner right wall of the cavity groove 12 through a bearing.

[0026] Through the above scheme: the operator rotates the handle 131, which drives the bidirectional lead screw 130 to rotate. When the bidirectional lead screw 130 rotates, the two driving blocks 132 will move in opposite directions or in a straight line under the action of the lead screw. When the driving blocks 132 move, the limiting post 133 will pass through the through hole 134. When it is necessary to connect the components, rotate the handle 131 to make the two driving blocks 132 move towards each other. The limiting post 133 passes through the through hole 134 and is movably locked inside the limiting hole 5, realizing the installation and fixation of the positioning block 4. When it is necessary to disassemble, rotate the handle 131 in the opposite direction to make the two driving blocks 132 move in opposite directions. The limiting post 133 will exit from the limiting hole 5, completing the disassembly.

[0027] In this embodiment, the blocking device 9 includes a mounting rod 91, a handle 92 is provided at the upper end of the mounting rod 91, a screw 93 is fixedly installed at the middle of the lower end of the mounting rod 91, a first mounting sleeve 94 is movably sleeved on the outer surface of the mounting rod 91, a warning tape 95 is fixedly installed at the right end of the first mounting sleeve 94, and a second mounting sleeve 96 is provided at the right end of the warning tape 95; the mounting rod 91 is threadedly installed at the middle of the upper end of the traffic cone body 8 by the screw 93.

[0028] With the above solution: During installation, the first mounting sleeve 94 is fitted onto the outer surface of the mounting rod 91. Since the lower middle part of the mounting rod 91 is fixedly installed with a screw 93, the screw 93 is aligned with the upper middle part of the traffic cone body 8, and the mounting rod 91 is installed on the traffic cone body 8 by means of threaded connection. When it is necessary to expand the blocking range, the second mounting sleeve 96 can be pulled to unfold the warning tape 95, and then the second mounting sleeve 96 is installed above the adjacent traffic cone body 8.

[0029] It should be noted that this utility model is a traffic cone for road and bridge construction. During use, the base 1 is placed on the ground around the construction area. Several gripping teeth 2 at the lower end of the base 1 are inserted into the ground to increase the friction and gripping force with the ground, preventing the traffic cone from sliding or shifting as a whole and ensuring its stability. The weight of the base 1 is increased by the annular counterweight 11, which lowers the center of gravity of the traffic cone and further improves its stability, making it less likely to tip over. When assembling the base 1 and the traffic cone body 8, the positioning block 4 is placed in the positioning groove 3. Then, the operator rotates the rotating handle 131, which drives the bidirectional lead screw 130 to rotate. When the bidirectional lead screw 130 rotates, the driving blocks 132 on the left and right sides of its outer surface move in opposite or opposite linear motion under the action of the lead screw. When the driving blocks 132 move, the limiting post 133 passes through the through hole 134 in the middle of the left and right walls of the positioning groove 3 until the two limiting posts 133 are respectively The entire traffic cone body 8 can be quickly installed and fixed by engaging the limiting holes 5 at both ends of the positioning block 4. When disassembly is required, the handle 131 is rotated in the opposite direction, causing the block 132 to move in the opposite direction, and the limiting post 133 is disengaged from the limiting hole 5, thus completing the disassembly. When a specific area needs to be warned, the first mounting sleeve 94 is fitted onto the outer surface of the mounting rod 91, and the screw 93 at the lower end of the mounting rod 91 is aligned with the middle of the upper end of the traffic cone body 8. The mounting rod 91 is then fixed to the traffic cone body 8 by threaded connection. When the blocking range needs to be expanded, the second mounting sleeve 96 is pulled to unfold the warning tape 95, and then the second mounting sleeve 96 is installed above the adjacent traffic cone body 8 to form a continuous blocking warning area. The operator can easily move the overall position by holding the handle 92. The alarm 7 can emit an audible and visual warning signal to remind passing vehicles and pedestrians to pay attention to the construction area.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
