DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] Example 1

[0054] A railway signal receiving and detecting device comprises: a signal box 6, an optical fiber, and a signal box mounting assembly;

[0055] Railway signal reception and transmission usually involves setting up signal sections on the railway, with each section separated by an insulating section; then laying optical cables on the track as channel equipment for signal transmission; the optical cables are connected to the signal box 6; the signal box 6 receives the input signal and converts it into a specific optical signal after signal processing, and the optical signal is transmitted to the target section through the optical cable; after the receiver in the target section receives the optical signal, it decodes it and displays a suitable indicator light or sign according to the signal. The receiver can use a microelectronic phase-sensitive track circuit receiver.

[0056] The signal box 6 is usually set beside the track and does not affect the running of the train. In order to ensure the stability of the installation position of the signal box 6, a concrete pier is usually set beside the track, and then the signal box 6 is directly placed on the concrete pier, and the signal box is fixed to the concrete pier by drilling holes with bolts; this installation method does make the installation of the signal box 6 more stable; however, since the concrete pier is directly set beside the track, when the train passes through the track, it will generate vibrations, and these vibration energies will be transmitted to the concrete pier, and then transmitted to the signal box 6 by the concrete pier. Since the signal box 6 is in direct contact with the concrete pier, it will be greatly affected by the vibration; it is likely to cause the components or signal lines in the signal box 6 to loosen, affecting the normal transmission of the signal.

[0057] like Figure 1As shown, in this embodiment, a concrete pouring pier 1 is also arranged below the signal box 6, but the signal box 6 is not directly installed on the concrete pouring pier 1; instead, the signal box 6 is first installed in the signal box installation assembly, and then a shock absorbing assembly is arranged between the signal box installation assembly and the concrete pouring pier 1;

[0058] The above-mentioned signal box installation assembly includes: a concrete casting pier 1, a support platform 3 and a fixing mechanism; the signal box 6 is placed on the support platform 3, and the signal box 6 and the support platform 3 are fixed by the fixing mechanism; the fixing mechanism is configured as protective side panels 4 vertically arranged on the four side edges of the support platform 3, and the height of the protective side panels 4 is the same as the height of the signal box 6; the protective side panels 4 just form a placement space for an enclosure above the support platform 3; after the signal box 6 is placed between the protective side panels 4, a press-on locking plate 5 is fixed above the protective side panels 4 by bolts, and the press-on locking plate 5 covers the signal box 6, and fixes the signal box 6 in the placement space formed by the support platform 3 and the protective side panels 4.

[0059] As a preferred embodiment, the upper pressing locking plate 5 is improved from a one-piece structure into four separate upper pressing locking plates 5; one upper pressing locking plate 5 is fixed above two adjacent protective side plates 4 by bolts; the four upper pressing locking plates 5 are pressed at the four top corners of the signal box 6. In this way, the upper surface of the signal box 6 will not be completely blocked; part of the upper surface of the signal box 6 has a detachable box cover or display screen; the upper surface of the signal box 6 is exposed, and the box cover can be opened or the display screen can be observed without removing the upper pressing locking plate 5; and the four upper pressing locking plates 5 are fixedly pressed at the four top corners of the signal box 6, and the signal box 6 can also be fixed on the support platform 3.

[0060] The shock-absorbing component arranged between the lower surface of the support platform 3 and the upper surface of the concrete casting pier 1 is configured as a shock-absorbing column 2; the shock-absorbing column 2 here adopts a hydraulic damping shock-absorbing column, which is an existing product that can be purchased directly, and its detailed structure is not repeated here; a shock-absorbing column 2 is arranged at each of the four top corners below the support platform 3; the end of the shock-absorbing column 2 that contacts the concrete casting pier 1 can be partially directly cast in the concrete casting pier 1; it can also be directly fixed to the concrete casting pier 1 by punching bolts.

[0061] When a train passes by the track next to the signal box 6, the vibration generated by the ground is transmitted to the concrete pier 1, and the vibration energy is absorbed and reduced under the action of the hydraulic shock-absorbing column 2, thereby preventing the signal box 6 from generating large-scale vibrations, thereby preventing the components or signal lines inside the signal box 6 from loosening.

[0062] Example 2

[0063] Based on Example 1, in Example 1, four shock-absorbing columns 2 are arranged between the support platform 3 and the concrete pouring pier 1 to absorb and reduce the impact of vibration energy on the signal box 6;

[0064] like Figure 3 As shown, on the basis of the shock-absorbing column 2, in order to minimize the vibration energy received by the signal box 6 as much as possible; in this embodiment, an elastic support frame 7 is arranged between the lower surface of the support platform 3 and the upper surface of the concrete pouring pier 1;

[0065] Two groups of elastic support frames 7 are provided;

[0066] like Figure 4 As shown, two groups of elastic support frames 7 are arranged in left-right mirror symmetry; each group of elastic support frames 7 is composed of two arc plate support bodies 701 that are mirror symmetric up and down; one side of the two arc plate support bodies 701 is connected into one body, which is defined as the closing side. The arc plate support body 701 is made of a material with elasticity and good toughness; the arc plate support body 701 has a certain thickness; when vibration occurs, the elastic support frame 7 will produce a certain deformation to achieve the effect of absorbing and reducing the vibration; in conjunction with the shock absorbing column 2, the signal box 6 can be shock-absorbed and buffered to the greatest extent.

[0067] As a preferred embodiment, a spring ring 702 is arranged between two groups of elastic support frames 7; one end of the spring ring 702 is connected to the closing edge of one group of elastic support frames 7, and the other end of the spring ring 702 is connected to the closing edge of the other group of elastic support frames 7. The elastic support frames 7 on both sides are deformed under the action of vibration, and the relative closing edges will approach each other;

[0068] A spring ring 702 is arranged between two opposite closing edges, so that when the elastic support frame 7 is deformed, the closing edges approach each other and squeeze the spring ring 702; when the vibration disappears, the elastic support frame 7 recovers, and the spring ring 702 also recovers; the addition of the spring ring 702 combines the two independent elastic support frames 7 into one, and makes the connection between the elastic support frame 7 and the concrete pouring pier 1 more stable.

[0069] Example 3

[0070] Based on Example 1, in Example 1, the signal box 6 is placed on the support platform 3, and is fixed to the support platform 3 by the protective side panels 4 and the upper pressure locking plate 5; if the signal box 6 is damaged by force majeure or human damage, causing it to leave the support platform 3; at this time, it may not be known by the staff in the first time, and emergency measures may not be taken immediately; this will cause interruption of signal transmission and affect driving safety.

[0071] like Figure 5As shown, in this embodiment, a pressure sensor 9 is embedded in the center of the upper surface of the support platform 3; the pressure sensor 9 is connected to the PLC for communication, and the detection signal of the pressure sensor 9 can be transmitted to the control room by the PLC via the optical cable; when the signal box 6 is normally placed on the surface of the support platform 3, the pressure value generated by the signal box 6 on the pressure sensor 9 is constant, and the monitoring situation is normal at this time; when the signal box 6 is damaged and detached from the support platform 3, the signal value monitored by the pressure sensor 9 suddenly changes, and the PLC transmits this monitoring signal to the control room, determines that the signal box 6 has an abnormality, and urgently reminds the staff to take measures and organize fault investigation and repair.

[0072] Example 4

[0073] Based on Example 1, the signal box 6 is arranged beside the track; when the train passes at high speed, the air flows very quickly on the side facing the train, so the air pressure on the side facing the train becomes smaller; at this time, an obvious air pressure difference will be formed on both sides of the signal box 6. Under the action of this air pressure difference, an attraction will be generated on the entire signal box 6 toward the track side, which may cause the original fixing mechanism of the signal box 6 to loosen due to the unbalanced attraction over a long period of time, causing hidden dangers.

[0074] like Figure 2 As shown, in this embodiment, a high-speed fan 8 is arranged on the side of the concrete pouring pier 1 facing away from the track; an L-shaped air outlet 801 is arranged on the air outlet of the high-speed fan 8. The high-speed fan 8 is connected to the PLC arranged in the signal box 6. When the signal detects that a train is approaching, the PLC controls the high-speed fan 8 to operate, generates strong wind force, and blows from the L-shaped air outlet 801 to the side of the signal box 6 facing away from the track, so that the air flow on the side facing away from the track is also accelerated, and the pressure difference on both sides of the signal box 6 is reduced as much as possible; and the signal box 6 is prevented from being subjected to excessive attraction to the train side.

[0075] Example 5

[0076] Based on Example 1, optical fiber is an important channel device for railway signal transmission and plays the role of a signal channel. If the optical fiber is damaged, the signal transmission will be interrupted.

[0077] like Figure 6 As shown, this embodiment provides an optical fiber sheath 10 for protecting an optical cable from external force majeure, environmental effects or human damage;

[0078] The optical fiber sheath 10 is detachably wrapped on the optical cable to protect the optical cable; the optical fiber sheath 10 is set as a semi-circular plate structure with two independent plates; the two semi-circular plate structures can just cover the optical fiber when they are closed;

[0079] A fixing ear plate 1001 is provided on the two semicircular arc plate structures; by tightening the screws on the fixing ear plate 1001, the two semicircular arc plate structures can be connected and fixed, so that the optical cable is covered inside.

[0080] As a preferred embodiment, Figure 7 As shown, the optical fiber sheath 10 includes an outer protective shell 1002, a thermal insulation layer 1003 and a heat conductive layer 1004;

[0081] An interlayer is arranged in the outer protective shell 1002, and a heat-insulating layer 1003 and a heat-conducting layer 1004 are arranged in the interlayer from the outside to the inside. The heat-conducting layer 1004 is made of a material with good heat-conducting performance; when the optical cable is at normal temperature or high temperature, the heat-conducting layer 1004 will absorb and introduce heat into the inside of the optical cable; when the optical cable is in a low temperature environment, the heat-insulating layer 1003 can prevent a large amount of temperature loss inside the optical cable; and prevent the optical fiber from being in a low temperature environment, which affects the physical properties of the optical fiber, causing the signal to be attenuated or even lost when the signal is transmitted in the optical fiber.
