Description

Technical Field

[0001] This utility model relates to the technical field of railway vehicle identification systems, and in particular to an antenna protection device. Background Technology

[0002] A railway vehicle identification system refers to the technology and equipment used to read and process the model and number markings on railway vehicles at fixed locations. Railway operators must collect vehicle number data to manage the dispatching and handover of freight cars, the allocation of empty cars, and the regular maintenance of vehicles, in order to promptly and accurately ascertain the location and usage status of freight cars.

[0003] Antenna protection devices are an important component of railway vehicle identification systems. Currently, the overall structure of antenna protection devices, as shown in patent application number CN200920133520.4 entitled "Outdoor Antenna Installation Structure for Railway Vehicle Identification System," mainly includes an antenna mounting base and an antenna body. The antenna body is fixed on the antenna mounting base, which is then erected and fixed between two adjacent sleepers to complete the installation of the antenna protection device on the railway track.

[0004] Because ballast is laid between adjacent sleepers, railway maintenance involves tidying up the ballast between adjacent sleepers. This process uses a tamping machine, which tamps and moves the ballast on both sides of a single sleeper. Therefore, the antenna protection device must be removed before the tamping machine can operate smoothly, and then reinstalled afterward to ensure the antenna functions properly. This results in the existing antenna protection device being unfavorable for subsequent railway maintenance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an antenna protection device that changes the installation position of the antenna body so that the antenna mounting base does not need to be removed when the tamping machine is working, which is beneficial to railway maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an antenna protection device, comprising a mounting base and an antenna body, wherein the mounting base includes a mounting component and at least one connecting component, wherein the antenna body is fixed above the mounting component, the connecting component is located below the mounting component, and the mounting component and the connecting component are connected so that the mounting component is fixed on any sleeper.

[0008] The mounting components in this application can be plate-shaped or block-shaped, with their dimensions set according to the width of the antenna body and the sleeper. The connecting components can be connecting rods directly fixed to the sleeper or connecting rods installed below the sleeper. During installation, the mounting components are located above the sleeper. After connecting the connecting components and the mounting components, the entire antenna protection device can be connected to any single sleeper. This connection method allows the antenna protection device to be maintained during railway maintenance without removal. The tamping machine's operating claws can be directly inserted into the ballast between adjacent sleepers to tamp and move the ballast on both sides of the sleeper towards the target sleeper. The antenna protection device of this application facilitates the railway maintenance process and simplifies railway maintenance procedures.

[0009] Furthermore, the mounting component has a mounting platform, the antenna body is fixed above the mounting platform by a fastener, the sleeper is located below the mounting platform, and the connector is located below the sleeper.

[0010] Furthermore, at least one reinforcing connecting rod is fixed below the installation platform, and the reinforcing connecting rod is connected to the corresponding connector.

[0011] Furthermore, the connector has a fixed connecting rod located below the sleeper along the vertical length direction of the sleeper, and a reinforcing connecting rod located above the sleeper and parallel to the fixed connecting rod. The reinforcing connecting rod and the fixed connecting rod are fixed together so that the mounting component is fixed on any sleeper.

[0012] Furthermore, the fixed connecting rod is provided with two threaded sleeves facing the sleeper, and the reinforcing connecting rod is passed through two bolt connecting rods, each bolt connecting rod being threadedly connected to the corresponding threaded sleeve.

[0013] Furthermore, the fasteners include a fixed mounting plate and a movable mounting plate disposed opposite each other on the mounting platform, with the antenna body located between the fixed mounting plate and the movable mounting plate and fixed to the mounting platform.

[0014] Furthermore, the fixed mounting plate is fixedly connected to the mounting platform, while the movable mounting plate is detachably connected to the mounting platform.

[0016] Furthermore, each of the two folded edges is fixed to the antenna body by at least one pin.

[0017] Furthermore, it also includes at least two shock-absorbing pads, which are spaced apart and located between the bottom of the antenna body and the upper surface of the mounting platform. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1 , 2 As shown, an antenna protection device includes a mounting base 100 and an antenna body 200. The components of the antenna body 200 and the antenna wires are not specifically described in this application; their principles can be referenced from existing technologies (publication numbers CN201440453U and CN212011230U). This application mainly improves the installation position of the antenna protection device and the sleeper 300. Simultaneously, in conjunction with the change in installation position, the overall structure of the mounting component 110 is modified. Therefore, the overall structure of the mounting base 100 will be described in the various embodiments of this application to enable the entire antenna protection device to be connected to any single sleeper 300.

[0025] Specifically, the mounting base 100 includes a mounting member 110 and at least one connector 120. To improve the connection stability between the mounting base 100 and the sleeper 300, in this embodiment, there are two connectors 120, both of which are connected to the mounting member 110, so that the entire mounting base 100 is fixed to a single sleeper 300 in a wraparound manner. Specifically, the antenna body 200 is fixed above the mounting member 110, and the connector 120 is located below the mounting member 110, with the mounting member 110 and the connector 120 connected, so that the mounting member 110 is fixed to any sleeper 300.

[0026] It is understood that the mounting component 110 in this application can be plate-shaped or block-shaped, and its size is set according to the width of the antenna body 200 and the sleeper 300; the connecting component 120 can be a connecting rod directly fixed to the sleeper 300, or it can be a connecting rod installed below the sleeper 300; during installation, the mounting component 110 is located above the sleeper 300. After connecting the connecting component 120 and the mounting component 110, the entire antenna protection device can be connected to any single sleeper 300. This connection method allows the antenna protection device to be maintained during railway maintenance without removal. The tamping machine's operating claws can be directly inserted into the ballast between adjacent sleepers 300 to tamp and move the ballast on both sides of the sleeper 300 toward the target sleeper 300. The antenna protection device of this application is beneficial to the railway maintenance process and simplifies the railway maintenance operation steps.

[0027] Since the mounting component 110 of this application is fixed to a single sleeper 300, and the overall structure of the sleeper 300 is a rectangular strip structure, or a recessed flat structure is provided in the middle of the upper surface of the sleeper 300; regardless of the structure of the sleeper 300, the upper surface of the sleeper 300 is basically a horizontal surface structure. Therefore, in order to ensure that the mounting component 110 of this application can be stably mounted on the upper surface of the sleeper 300, such as Figure 1 , 2 As shown in Figures 3 and 4, the mounting component 110 of this application has a mounting platform 111. The antenna body 200 is fixed above the mounting platform 111 by the fixing component 130. The sleeper 300 is located below the mounting platform 111, and the connector 120 is located below the sleeper 300. The connection method of the mounting base 100 is equivalent to "clamping" and fixing the sleeper 300 by the connector 120 and the mounting component 110. This method does not require changing the structure of the sleeper 300, ensuring the installation strength of the sleeper 300. At the same time, it can also ensure that the antenna protection device can fix a single sleeper 300, which facilitates the maintenance operation of railway tracks by tools such as tamping machines.

[0028] Normally, the mounting platform 111 can be directly fixed using long bolts and connectors 120. However, given that the antenna body 200 requires wiring, to facilitate antenna wiring, such as... Figure 3 , 4As shown, this application has at least one reinforcing connecting rod 112 fixed below the mounting platform 111. The reinforcing connecting rod 112 contacts the upper surface of the sleeper 300. Due to the presence of the reinforcing connecting rod 112, a gap exists between the mounting platform 111 and the upper surface of the sleeper 300, which facilitates cable routing. Furthermore, the thickness of the reinforcing connecting rod 112 can be set according to the required gap size for cable routing. The presence of the reinforcing connecting rod 112 also increases the deformation resistance of the entire mounting platform 111. The reinforcing connecting rod 112 is directly connected to the connector 120, dispersing the connection force between the mounting platform 111 and the connector 120, thus increasing the connection stability between the mounting base 100 and the sleeper 300. To facilitate a stable connection between the reinforcing connecting rod 112 and the connector 120, the number of reinforcing connecting rods 112 and the number of connectors 120 in this application are the same, both being two, and each reinforcing connecting rod 112 is connected to its corresponding connector 120.

[0029] To limit the direction of cable routing or installation location, this application provides a cable routing channel 1111 on the installation platform 111. The cable routing channel 1111 is located on any side of the sleeper 300. The wires in the space between the installation platform 111 and the sleeper 300 finally pass through the cable routing channel 1111 and connect to the power supply equipment in the railway system so as to ensure the normal use of the antenna protection device.

[0030] To facilitate a secure connection between the connector 120 and the corresponding reinforcing connector 120, such as Figure 3 , 4 As shown, the connector 120 of this application has a fixed connecting rod 122, which is located below the sleeper 300 along the length direction perpendicular to the sleeper 300. A reinforcing connecting rod 112 is located above the sleeper 300 and parallel to the fixed connecting rod 122. The reinforcing connecting rod 112 and the fixed connecting rod 122 are fixed together so that the mounting component 110 is fixed on any sleeper 300. The two ends of the fixed connecting rod 122 are located on both sides of the sleeper 300 to be assembled. The two ends of the fixed connecting rod 122 or the position near its ends are fixed by long bolts and the reinforcing connecting rod 112 at the upper position, which can realize the assembly operation of the entire mounting base 100 and the sleeper 300.

[0031] Because different sleepers 300 have varying thicknesses, to facilitate a stable connection between the fixed connecting rod 122 and the reinforcing connecting rod 112, this application provides two threaded sleeves 121 on the fixed connecting rod 122, facing the sleeper 300. The reinforcing connecting rod 112 has two bolted connecting rods 1121 passing through it, and each bolted connecting rod 1121 is threadedly connected to its corresponding threaded sleeve 121. For example... Figure 2 , 3As shown in Figure 4, the two threaded sleeves 121 on each fixed connecting rod 122 are located at both ends of the fixed connecting rod 122, and the sleeper 300 is located between the two threaded sleeves 121. During installation, the bolt connecting rod 1121 on each reinforcing connecting rod 112 and the corresponding threaded sleeve 121 are locked together to assemble the two fixed connecting rods 122 and the corresponding two reinforcing connecting rods 112, thereby fixing the mounting base 100 and the sleeper 300. It is worth noting that if the position of the bolt connecting rod 1121 that penetrates the reinforcing connecting rod 112 also needs to penetrate the mounting platform 111, then the bolt connecting rod 1121 connects to the corresponding threaded sleeve 121 after penetrating the mounting platform 111 and the reinforcing connecting rod 112.

[0032] Of course, the threaded sleeve 121 of this application can also use a conventional nut, and the nut and the fixed connecting rod 122 can be fixed by welding or other methods. When the bolt connecting rod 1121 is connected to the conventional nut, there is still a certain gap. In engineering, considering the connection stability, when the threaded sleeve 121 uses a conventional nut, the bottom of the bolt connecting rod 1121 should preferably be in contact with the bottom of the nut. In addition, in order to adapt to the sleeper 300 with large thickness variations when the bolt connecting rod 1121 is connected to the conventional nut, the factory length of the bolt connecting rod 1121 can be appropriately longer. At present, during installation, the length of the bolt connecting rod 1121 can be directly cut according to the thickness of the sleeper 300, which can also allow the bolt connecting rod 1121 to be connected to the conventional nut to match sleepers 300 with different thicknesses.

[0033] This application utilizes a fastener 130 to fix the antenna body 200 and the mounting platform 111. To facilitate the connection between the antenna body 200 and the mounting platform 111, as follows... Figure 3 , 4 As shown, the fixing member 130 includes a fixed mounting plate 131 and a movable mounting plate 132 disposed opposite to each other on the mounting platform 111. The antenna body 200 is located between the fixed mounting plate 131 and the movable mounting plate 132 and fixed to the mounting platform 111. The antenna body 200 is elongated, and the thickness of the antenna body 200 at both ends along its length is less than the thickness of the antenna body 200 in the middle. Therefore, the antenna body 200 and the mounting platform 111 can be fixed simply by snapping the antenna body 200 at both ends along its length onto the mounting platform 111. For this purpose, the fixed mounting plate 131 and the movable mounting plate 132 of this application are respectively disposed at both ends of the length of the antenna body 200 to achieve the fixation of the antenna body 200 and the mounting platform 111.

[0034] In conjunction with the structure of the antenna body 200, the fixed mounting plate 131 and the movable mounting plate 132 of this application are each provided with relatively extended folded edge structures 133, and the two folded edge structures 133 snap the antenna body 200 together. Figure 4As shown, both the fixed mounting plate 131 and the movable mounting plate 132 are L-shaped plate structures. The folded edge structure 133 is equivalent to the horizontal segment of the L-shaped plate structure. The vertical segment of the fixed mounting plate 131 and the mounting platform 111 are integrally connected. The movable mounting plate 132 and the mounting platform 111 are detachably connected. During installation, one end of the antenna body 200 is obliquely clamped under the folded edge structure 133 of the fixed mounting plate 131. Then, the antenna body 200 is pressed down onto the mounting platform 111. Next, the folded edge structure 133 of the movable mounting plate 132 is placed above the other end of the antenna body 200. Finally, the movable mounting plate 132 and the mounting platform 111 (or the adjacent reinforcing connecting rod 112) are fixed, thus completing the fixed assembly operation of the antenna body 200 and the mounting platform 111.

[0035] To simplify the installation process and reduce the positioning operations of the locking components (connecting bolts), the two folded structures 133, which cannot be applied for, are each fixed to the antenna body 200 by at least one pin 134. For example... Figure 3 , 4 As shown, each folded edge structure 133 is fixed with two pins 134. The two pins 134 are assembled on the folded edge structure 133. During installation, after the antenna body 200 is in place, the pins 134 are fixed to fix the folded edge structure 133 and the antenna body 200, thereby fixing the antenna body 200 and the mounting platform 111.

[0036] Since the antenna body 200 is fixed to the mounting platform 111 by applying pressure vertically under the action of the fixed mounting plate 131 and the movable mounting plate 132, in order to avoid rigid contact between the antenna body 200 and the mounting platform 111, and to minimize the risk of displacement caused by railway operation, this application also includes at least two shock-absorbing pads 1112. The two shock-absorbing pads 1112 are spaced apart and located between the bottom of the antenna body 200 and the upper surface of the mounting platform 111. The number of shock-absorbing pads 1112 can be 2, 3, 4, 6, etc., and the shock-absorbing pads 1112 are made of materials with anti-slip and shock-absorbing effects, such as rubber pads. During fixing, the bottom of the shock-absorbing pads 1112 is fixed to the upper surface of the mounting platform 111, and the tops of each shock-absorbing pad 1112 are basically on the same plane. When the antenna body 200 is connected to the mounting platform 111, the bottom of the antenna body 200 is in contact with the top of each shock-absorbing pad 1112. Under the action of the fixed mounting plate 131 and the movable mounting plate 132, each shock-absorbing pad 1112 can generate a certain deformation to facilitate the shock-absorbing connection between the antenna body 200 and the mounting platform 111. Figure 4As shown, this application provides four shock-absorbing feet 1112 according to the structure of the antenna body 200. The four shock-absorbing feet 1112 are arranged in a rectangular shape and correspond to or are in close contact with the four rectangular feet at the bottom of the antenna body 200, so as to realize the connection between the antenna body 1112 and the mounting platform 111.
