Description

Technical Field

[0001] The present invention relates to the field of geophysical exploration construction auxiliary equipment, and specifically relates to a cable and wire passing protection device. Background Art

[0002] In electrical method construction, it is necessary to lay transmitting cables, and ensure that the transmitter can be powered only after they are connected, and the receiving system can collect data. However, in surface electrical method construction, it is a common operation requirement for the transmitting cables to cross roads. Especially in areas with dense vehicle traffic, the transmitting cables are frequently run over by vehicles, and it is easy to occur such situations as damaged outer skins and broken internal wires, resulting in abnormal signal transmission, construction interruption, high maintenance costs and long time consumption.

[0003] Existing protection measures are simple. For example, only ordinary rubber pads or simple wire grooves are used, which cannot effectively cope with complex traffic conditions, and it is difficult to achieve damage-free protection of the transmitting cables, and data collection cannot be carried out normally. If the existing device is not fixed by means such as steel nails and expansion wires, when the vehicle speed is too high, the existing protection device is easily carried away by the high-speed vehicle, which not only cannot play a protective role, but also easily increases traffic safety hazards. If steel nails or expansion wires are used for fixing, the road surface will be damaged to varying degrees.

[0004] After retrieval, it is found that a cable and wire passing protection device with an authorization announcement date of March 7, 2023 realizes the purpose of damage-free protection of passing cables and wires, but it is necessary to dig a groove on the road surface, causing varying degrees of damage to the road surface, and its use is subject to certain limitations. Therefore, it is necessary to develop a protection device for laying passing transmitting cables without damaging the road surface to achieve the purpose of all-round and damage-free protection of passing transmitting cables and the road surface, and ensure the smooth progress of construction. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cable and wire passing protection device, which not only effectively protects the passing transmitting cables, but also does not damage the road surface, and its installation and disassembly are very convenient, meeting the construction progress requirements and ensuring the data collection quality.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: The present invention includes an arc-shaped top plate and a bottom plate corresponding to the top plate. A channel for passing cables and wires is formed between the top plate and the bottom plate. A filler for clamping the cables and wires is provided in the channel. A suction cup fixedly connected to the road surface by adsorption is fixedly provided on the bottom plate. The suction cup is hermetically connected to an air extraction device through a communicating pipe provided in the channel.

[0007] A further improvement of the present invention lies in that: the suction cup is connected to the bottom plate through a connector fixed thereto, and the connector is connected to a hole with internal threads provided on the corresponding bottom plate through external threads.

[0008] A further improvement of the present invention lies in that: the internal threads of the connector are connected through a connecting member provided with external threads and mating therewith, and the connecting member is connected to the air extraction device through a connecting pipe.

[0009] A further improvement of the present invention lies in that: the suction cup is made of rubber sponge and is evenly distributed on the bottom plate.

[0010] A further improvement of the present invention lies in that: a wire passing unit for cables and wires to pass through is provided in the channel, and the wire passing unit is made of silica gel material.

[0011] A further improvement of the present invention lies in that: the wire passing unit is a wire passing pipe or a wire passing groove.

[0012] A further improvement of the present invention lies in that: side plates for convenient handling are provided on both sides of the top plate.

[0013] A further improvement of the present invention lies in that: holes for mating with connecting hooks are provided at the ends of the top plate and the side plates, and adjacent top plates and side plates are connected together through the holes and the connecting hooks mating therewith.

[0014] A further improvement of the present invention lies in that: a support rod is provided between the side plate and the road surface, and the height of the support rod is between the self-height of the suction cup and the height of the suction cup after air extraction.

[0015] A further improvement of the present invention lies in that: reflective warning strips and guiding arrow marks are provided on the surface of the top plate.

[0016] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present invention are as follows: The present invention has a simple structure and novel design. The device is fixedly adsorbed on the road surface through the suction cup fixed to the bottom plate, achieving the fixation of the device to the road surface without damaging the road surface. It also plays an appropriate protective role for the passing cables and wires. The device effectively protects the passing transmission cables and wires from multiple aspects such as compression resistance, buffering, and positioning, greatly reducing the risk of the cables and wires being rolled and worn when passing through the road, and completely realizing non-destructive protection. Utilizing the characteristics of high resilience and airtightness of rubber sponge, it ensures that the suction cup made of rubber sponge firmly adsorbs on the road surface during the working process. The development and use of this device not only facilitate electrical method construction but also are conducive to the protection of public facilities, achieving multiple benefits and being necessary for promotion.

[0017] Figure 1 It is the front view sectional structure schematic diagram of the present invention; Figure 2It is a schematic top view structure of the present invention; Figure 3 It is a schematic structure diagram of the working principle of the suction cup of the present invention.

[0019] The present invention will be further described in detail below in conjunction with embodiments: A cable and wire road crossing protection device, as Figures 1 - 3 shown, which includes an arc-shaped top plate 2 and a bottom plate 7 corresponding to the top plate 2. The surface of the top plate 2 is provided with a reflective warning strip and a guiding arrow mark. The reflective warning strip can attract the attention of drivers under light irradiation, and the guiding arrow mark can guide vehicles to drive along the correct trajectory, reducing accidental damage to the device.

[0020] A channel for passing cable and wire across the road is formed between the top plate 2 and the bottom plate 7. The top plate 2 is made of special alloy steel, which has high compressive resistance, wear resistance and impact resistance, and is sufficient to withstand the rolling and friction of vehicles. Placing the cable and wire passing across the road in the channel formed by the top plate 2 and the bottom plate 7 can effectively protect the cable and wire passing across the road.

[0021] As Figure 1 shown, a filler 4 for clamping the cable and wire is provided in the channel. The filler 4 is composed of rubber or polyurethane foam material, which can effectively absorb the impact force generated by vehicle rolling, avoid its direct action on the internal cable and wire, and effectively protect the cable and wire therein.

[0022] To adapt to roads of different widths, holes for cooperating with connection hooks are opened at the ends of the top plate 2 and the side plate 1. When the road is too wide and the device needs to be lengthened, as long as the corresponding top plates 2 and bottom plates 7 on both sides are reliably connected together with connection hooks, at this time, the channel formed by the top plate 2 and the bottom plate 7 is also lengthened accordingly, effectively protecting the cable and wire passing across the road in the channel. Its installation and disassembly are very convenient, achieving the protection of the cable and wire passing across the road without damaging the road surface.

[0023] As Figure 1 and Figure 3As shown in the figure, a suction cup 6 fixed to the road surface is provided on the bottom plate 7. The suction cup 6 is hermetically connected to an air extraction device 10 through a connecting pipe 9 arranged in a channel. The suction cup 6 is made of rubber sponge and is evenly distributed on the bottom plate 7. The rubber sponge is a highly elastic material with a porous structure, mainly composed of rubber and a foaming agent, having excellent high resilience and softness, which is beneficial to the buffering and shock absorption of the device; it has good sound insulation effect and good ability to absorb impact loads, and has good load-bearing capacity. During the working process, the air extraction device 10 sucks away the gas in the suction cup 6 through the connecting pipe 9. The reaction force of the device exhausting backward pushes the suction cup 6 towards the road surface, closing the air inlet of the suction cup 6. The vacuum degree in the suction cup 6 increases, forcing the highly elastic rubber sponge to embed and block the gaps in the road surface. The further increase in the vacuum degree in the suction cup 6 makes the adsorption force of the suction cup 6 reach the maximum value, achieving the firm adsorption of the device on the road surface without damaging the road surface and preventing the deviation of the device. This process is mainly achieved instantaneously by the high resilience characteristics of the suction cup 6 made of rubber sponge.

[0024] As Figure 3 shown in the figure, the suction cup 6 is connected to the bottom plate 7 through a joint 5 fixed to it. The joint 5 is connected to a hole with internal threads opened on the corresponding bottom plate 7 through external threads. The internal threads of the joint 5 are connected through a connecting piece 8 provided with external threads and matched with it. The connecting piece 8 is connected to the air extraction device 10 through a connecting pipe 9. Through the above connection, a hermetic connection between the suction cup 6 and the air extraction device 10 during the working process is achieved, ensuring that the air extraction device 10 completely sucks away the gas in the suction cup 6.

[0025] When the air extraction device 10 is not turned on, to ensure that the device is placed stably on the road surface and the suction cup 6 is not oppressed by the device, avoiding affecting the service life. A support rod 1-1 can be placed between the side plate 1 and the road surface to temporarily support the device. The height of the support rod 1-1 is greater than the self-height of the suction cup 6 and less than the height of the suction cup 6 after the air is sucked away. Therefore, after the air extraction device 8 is turned on, the height of the suction cup 6 increases after the air in it is sucked away. The increased suction cup 6 is firmly adsorbed to the road surface. At this time, the support rod 1-1 continuously moves away from the road surface, and only the suction cup 6 adsorbed to the road surface firmly supports the device, achieving the purpose of fixing the device to the road surface without damaging the road surface. As Figure 2 shown in the figure, the side plates 1 are arranged on both sides of the top plate 2, which not only facilitates the placement of the support rod 1-1 but also facilitates the handling of the device, and also plays a certain protective role for the suction cup 6 arranged below the bottom plate 7.

[0026] As Figure 1As shown, a wire passing unit 3 for cables and wires to pass through is provided in the channel. The wire passing unit 3 is made of silica gel material, which is soft and has a certain toughness. According to the outer diameter of the passing transmission cables and wires, it can be designed into a wire passing pipe or a wire passing groove with a specific shape to ensure the stable placement of the cables and wires and prevent them from being damaged due to offset within the device.

[0027] Finally, it should be noted that the above embodiments are only examples for clearly illustrating the present invention and are by no means limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here, and the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
