Description

Technical Field

[0001] The invention relates to the technical field of protective devices, and in particular to a protective device for laying cables in existing conventional railways. Background Art

[0002] Existing conventional railways refer to railway lines that have been completed and officially put into operation. The notable feature of such lines is that the train speed is relatively low. In the process of laying cables on existing conventional railways, there may be various debris along the railway, which is very likely to cause damage to the cables. Therefore, under normal circumstances, the cables need to be laid in special protective devices to provide effective protection for the cables, avoid damage by debris, and ensure that the cables can run safely and stably.

[0003] According to the application number: CN201911178639.8, a protective device for cable laying is disclosed, which relates to the field of cable laying technology. It includes a cable trench and a rolling assembly, the cable trench includes a plurality of cable trench monomers connected end to end, the cable trench monomer includes two side panels arranged side by side and a bottom plate arranged between the two side panels, and the lower end of the side panel is connected to the bottom plate; the rolling assembly includes a telescopic rod, a connecting rod, and a roller, the upper end of the telescopic rod is hinged to the side panel, the lower end of the telescopic rod is hinged to one end of the connecting rod, the roller is rotatably connected to the connecting rod, the telescopic rod is connected to the side panel through a first retaining screw, and the telescopic rod is connected to the connecting rod through a second retaining screw. The present invention can prevent the loss of sand and soil in the cable trench, thereby preventing the cable from being exposed in the cable trench and preventing the cable from being dug up.

[0004] However, in the actual operation of existing conventional railways, the existing cable laying protection devices are in use. When faced with the need to expand the cable capacity, since the installed cable laying protection devices themselves have fixed specifications and limited internal space, it is difficult to accommodate the newly added cables. Therefore, usually only another set of cable laying protection devices can be added to lay the new cables. This will undoubtedly increase the cost investment in many aspects such as corresponding material procurement, construction and installation, resulting in a relatively high overall cost of use.

[0010] Furthermore, the assembly mechanism also includes: a partition fixing plate and a hinged plate; the partition fixing plates are provided in plurality, and the plurality of partition fixing plates are fixedly connected to the upper end surface of the telescopic sliding plate; the hinged plates are provided in plurality, and the plurality of hinged plates are respectively hinged to the upper ends of the plurality of partition fixing plates, and a torsion spring is provided at the hinge between the hinged plate and the partition fixing plate.

[0011] Furthermore, the expansion mechanism includes: a fixing rod, a combined threaded column and a connecting nut; the fixing rod is provided with two, and the two fixing rods are respectively fixedly connected to the lower end surfaces of the two first adjustment side plates; the combined threaded column is provided with two, and the two combined threaded columns are respectively fixedly connected to the lower end surfaces of the two fixing rods; the connecting nut is threadedly connected to the outer sides of the two combined threaded columns.

[0014] Beneficial Effects The present invention facilitates the installation of the protective device by setting an assembly mechanism, and the protective bottom plate and the telescopic sliding plate are pulled apart. The design of the connecting fixed block and the limiting slide groove can effectively limit the distance between the two. When the telescopic sliding plate is fully pulled apart, the assembling protrusion will be stuck on the inner side of the connecting installation groove under the elastic force of the installing spring sheet, so as to realize the limitation between the protective bottom plate and the telescopic sliding plate. By slidingly connecting the assembly blocks of another group of protective devices to the inner side of the connecting assembly groove, the assembly and integration of two or more groups of protective devices can be realized. In addition, after the hinged plate is opened, the cable can be placed on the inner side of the partition fixing plate, thereby completing the cable laying work. It can also be placed on the inner sides of different partition fixing plates according to the cable conditions of different equipment, thereby realizing the classified management of cables, which not only makes the installation process more convenient, but also makes it more convenient to carry out subsequent maintenance work, effectively improves work efficiency, and reduces labor intensity at the same time.

[0015] In addition, the expansion of the protective device is achieved by setting the expansion mechanism. When there is a need to expand the protective device later, the two first adjusting side panels can be pulled apart by rotating the corresponding connecting nut and unscrewing it, thereby expanding the space inside the two first adjusting side panels. During the sliding of the first adjusting side panel, it will drive the second adjusting side panel to slide outward synchronously, so as to achieve the purpose of expansion. Moreover, after the first adjusting side panel is opened, the limiting hinge rod will tilt downward under the action of gravity, and then be stuck on the inner side of the limiting fixing frame, so as to limit the first telescopic plate. By loosening the fastening bolts, the fastening bolts will no longer clamp the connecting plate. At this time, the first top cover and the second top cover can be pulled apart to match them with the expanded first adjusting side panel. In this way, the later transformation of the protective device is facilitated, which not only effectively improves work efficiency, but also reduces labor intensity, while also reducing the cost of use.

[0016] In addition, through the setting of the above-mentioned mechanism, the installation of the protective device becomes more convenient, which not only significantly improves the overall work efficiency, but also reduces the labor intensity of relevant personnel. At the same time, the setting also gives the protective device expandable functions, further improves work efficiency, reduces the labor burden again, and reduces the cost of use to a certain extent, which brings many conveniences to the development of related work.
