Description

Technical Field

[0001] The utility model relates to the technical field of steel material transport auxiliary devices, in particular to a spanning device. Background Art

[0002] In production workshops, coil transfer equipment is often installed in underground pits. To protect the equipment and ensure safe passage for employees, a pass-through device is required. A pass-through device is a structure used to provide safe passage in a specific environment. It is usually used to cover underlying equipment, pipelines, etc., allowing personnel to pass safely and conveniently without interfering with or damaging the underlying facilities. Pass-through devices are essential safety features in industrial production environments, not only improving work safety but also optimizing personnel flow management during the production process.

[0003] Existing overpasses typically use connecting plates to connect the two sides of a pit for temporary pedestrian passage. During pedestrian passage, the connecting plates may be displaced to a certain extent, posing a risk of pedestrians stepping on air or accidentally falling, greatly increasing safety hazards in industrial environments. At the same time, if a fall occurs, the equipment in the pit (such as oil pipes, drag chains, etc.) will be exposed and likely to be directly impacted or compressed, resulting in damage to the equipment or malfunction, increasing the cost and complexity of equipment maintenance. Therefore, there is room for improvement. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the present invention provides a crossing device to solve the technical problems that the existing crossing devices have poor stability, certain safety hazards, and are not conducive to the normal passage of pedestrians and equipment protection.

[0005] The utility model is achieved through the following technical solutions:

[0006] A crossing device includes a first connecting plate and a second connecting plate, wherein the first connecting plate and the second connecting plate are respectively arranged on both sides of a pit, an installation groove is provided in the first connecting plate, a cylinder and a plug plate are provided in the installation groove, and a slot is provided on the second connecting plate, wherein the cylinder is used to drive the plug plate to be plugged into the slot.

[0007] Preferably, a slide rail is further provided in the installation groove, a sliding member is provided on the inserting plate, the sliding member is slidably matched with the slide rail, and the cylinder drives the inserting plate to slide along the slide rail.

[0008] Preferably, the second connecting plate is further provided with a positioning groove, and positioning protrusions are provided on both sides of the plug plate, and the positioning protrusions are plug-fitted into the positioning groove.

[0009] Preferably, the upper end surfaces of the first connecting plate and the second connecting plate are also commonly provided with a first groove, and a cover plate is hinged on the first connecting plate, and the cover plate covers the first groove.

[0010] Preferably, second grooves are provided at the four corners of the first groove, and blocks are intersected in the second grooves, and the blocks are used to limit the displacement of the cover plate.

[0011] Preferably, the ends of the first connecting plate and the second connecting plate that are away from each other are both configured as slope structures.

[0012] The beneficial effects of the utility model are:

[0013] 1. By arranging cylinders, inserts, and slots between the connecting plates, the inserts are mechanically fixed, effectively reducing the displacement of the inserts when pedestrians pass through and maintaining the stability of the overpass. By inserting the inserts into the slots, the overpass maintains a high degree of safety during use, allowing pedestrians to pass more confidently and reducing accidents caused by instability.

The cover plate effectively prevents debris, tools or liquids from accidentally falling from above onto the plug-in board and other internal structures. The stopper positioning setting effectively limits the displacement of the cover plate under abnormal circumstances, ensuring that the cover plate will not be accidentally opened due to external impact or vibration, thereby protecting internal components and maintaining operational safety.

[0015] 3. Through the setting of the slide rail, the plug-in board can slide smoothly along the rail, so that the plug-in board can be accurately docked into the slot on the second connecting plate, achieving more reliable fixation and reducing the friction generated by the plug-in board during the plug-in and disengagement process, thereby reducing wear and damage and extending the service life of the cross-over device; through the cooperation of the positioning groove and the positioning protrusion, it is ensured that the plug-in board maintains a stable position after plugging, reducing the displacement of the plug-in board during use, and enhancing the stability and safety of the overall structure.

[0023] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0025] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1-Figure 3A crossing device includes a first connecting plate 1 and a second connecting plate 2. The first connecting plate 1 and the second connecting plate 2 are respectively arranged on both sides of a pit 3. A mounting groove 4 is provided in the first connecting plate 1. A cylinder 5 and a plug-in plate 6 are provided in the mounting groove 4. A slot 7 is provided on the second connecting plate 2. The cylinder 5 is used to drive the plug-in plate 6 to be inserted into the slot 7.

[0028] The mechanical fixation of the plug plate 6 is achieved between the connecting plates by the arrangement of the cylinder 5, the plug plate 6 and the slot 7, which effectively reduces the displacement of the plug plate 6 when pedestrians pass and maintains the stability of the crossing device; when pedestrians pass, the cylinder 5 will automatically drive the plug plate 6 to connect with the slot 7 on the second connecting plate 2, so that the connecting plates on both sides are firmly fixed together, rather than relying solely on gravity or friction, which significantly reduces the risk of people falling or falling; by inserting the plug plate 6 into the slot 7, the crossing device maintains a high degree of safety during use, pedestrians can pass more safely, and reduce accidents caused by instability; it effectively avoids the displacement of the board surface due to equipment aging, environmental impact or frequent use, and ensures the safety of pedestrians when walking on the bridge deck.

[0029] In order to simplify the installation and removal process of the plugboard 6 and ensure that the cylinder 5 can quickly and accurately move the plugboard 6 into place, based on this, in one embodiment, a slide rail 8 is further provided in the installation slot 4, and a sliding member is provided on the plugboard 6. The sliding member slides in cooperation with the slide rail 8, and the cylinder 5 drives the plugboard 6 to slide along the slide rail 8. The presence of the slide rail 8 allows the plugboard 6 to slide smoothly along the track, so that the plugboard 6 can be accurately docked into the slot 7 on the second connecting plate 2, achieving more reliable fixation and meeting specific needs under different usage frequencies and scenarios. By having the cylinder 5 drive the plugboard 6 to slide along the slide rail 8, the installation and removal process is simplified. When the cross-over device is needed, the cylinder 5 can quickly and accurately move the plugboard 6 into place, thereby completing the plugging operation. When it is not needed, the plugboard 6 can also be quickly retracted, facilitating routine maintenance or repair. The design of the slide rail 8 and the sliding member can reduce the friction generated by the plugboard 6 during the plugging and unplugging process, thereby reducing wear and damage and extending the service life of the cross-over device.

[0030] To provide a clear access point for plugboard 6 and enhance the crossover device's anti-interference capabilities, in one embodiment, a positioning slot 10 is further provided on the second connecting plate 2, and positioning protrusions 11 are provided on both sides of the plugboard 6. The positioning protrusions 11 engage with the positioning slots 10. The engagement of the positioning slots 10 and the positioning protrusions 11 ensures that the plugboard 6 maintains a stable position after insertion, reducing potential displacement of the plugboard 6 during use and enhancing the stability and safety of the overall structure. The positioning slots 10 provide a clear access point, ensuring that the plugboard 6 can be inserted at a precise angle and position, thereby avoiding poor connections caused by inaccurate positioning. Improving the splicing accuracy of the interface is crucial to ensuring pedestrian safety and enhances the crossover device's anti-interference capabilities.

[0031] To provide additional rigidity and effectively prevent debris from falling onto the plugboard 6 and other internal structures, in one embodiment, the upper end surfaces of the first connecting plate 1 and the second connecting plate 2 are also jointly provided with a first groove 12. A cover plate 13 is hingedly connected to the first connecting plate 1 and covers the first groove 12. The cover plate 13 is in direct and close contact with the upper end surface of the plugboard 6. The presence of the cover plate 13 forms a complete upper cover structure, providing additional rigidity and enhancing the interconnection between the first connecting plate 1 and the second connecting plate 2, thereby improving the stability of the entire device. The provision of the cover plate 13 effectively prevents debris, tools, or liquids from accidentally falling onto the plugboard 6 and other internal structures from above, reducing potential damage to pedestrians or equipment. The cover plate 13 above the cross-over device is flat and smooth, reducing possible protrusions and sharp edges, allowing pedestrians to pass more safely and reducing the risk of tripping.

[0032] In order to prevent deformation or shaking due to external forces and enhance the overall structural strength of the device, in one embodiment, second grooves 14 are provided at the four corners of the first groove 12, and blocks 9 are intersected in the second grooves 14. The blocks 9 are used to limit the displacement of the cover 13. The blocks 9 effectively limit the displacement of the cover 13 under abnormal circumstances, ensuring that the cover 13 will not be accidentally opened due to external impact or vibration, thereby protecting internal components and maintaining operational safety. Through restriction, the blocks 9 ensure that the cover 13 always maintains a close fit with the first groove 12 under normal working conditions, thereby enhancing stability and reducing the risk of slipping of the cover 13 due to improper operation. The provision of the blocks 9 provides additional support for the cover 13 in terms of physical structure, helping the cover 13 to remain stable, preventing deformation or shaking due to external forces, and thus enhancing the overall structural strength of the device.

[0033] In order to improve the safety of pedestrians and lower the center of gravity of the connecting plate, in one embodiment, the ends of the first connecting plate 1 and the second connecting plate 2 that are away from each other are both configured as slope structures. The slope structure provides a smooth transition area, allowing pedestrians and equipment to more conveniently cross the pit 3, avoiding the risk of falling due to height differences, especially for equipment such as carts; the slope structure can provide better friction through reasonable inclination angles and surface treatments, thereby reducing the risk of falling and slipping, and improving traffic safety; the slope design usually helps the natural drainage of water, reducing the risk of falling caused by wet surfaces, which is particularly important in rainy days or other humid environments; at the same time, the slope structure can lower the center of gravity, preventing overhead objects such as equipment or pedestrians from flipping or tilting due to gravity, further improving safety.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
