Description

Technical Field

[0001] The present application relates to the field of railway facilities, and in particular to a communication post for railways. Background Art

[0002] In the field of railway communication, with the continuous expansion of the railway transportation network and the continuous growth of transportation demand, reliable communication equipment is crucial for ensuring the safe operation and efficient dispatching of railways. A large number of communication facilities are required along the railway to ensure the timely transmission and communication of information. As a key component of the railway communication system, the communication post can provide a convenient communication channel for railway staff, enabling them to contact the dispatching center or other departments at any time along the line. This plays an indispensable role in handling emergencies, coordinating transportation work, and ensuring the normal operation of trains. At the same time, with the diversification of railway construction, such as the increase in special sections such as bridges, higher requirements are also put forward for the installation and use of communication posts in different environments.

[0003] In the past, the installation of railway communication posts mostly adopted simple fixing methods. A common practice was to connect the communication post to the installation foundation by welding. This method can ensure the stability of the communication post to a certain extent, but it is relatively complex during the installation process, and it is inconvenient for later maintenance and replacement. Another method is to use ordinary bolts for fixing. By drilling holes in the installation foundation and then inserting and tightening the bolts. However, in some special locations, such as when used on bridges, out of consideration for protecting the integrity of the bridge floor structure, the bridge floor cannot be damaged. Therefore, there is an urgent need to develop a communication post that can achieve rapid and efficient installation. Summary of the Invention

[0004] In order to achieve the rapid and simple installation of the communication post, the present invention provides a communication post for railways.

[0005] The communication post for railways provided by the present invention adopts the following technical solutions: A communication post for railways includes a column body, and an installation bottom plate is fixedly connected to the bottom end of the column body, and the installation bottom plate passes through the bridge guardrail; A box body is arranged outside the bridge guardrail, and the bottom of the box body is connected to the top of the installation bottom plate; A reinforcing frame is connected to the middle section of the column body, and the reinforcing frame passes through the bridge guardrail and is inserted into the box body; The fixing component is arranged inside the box body. The fixing component includes a driving rack, a driving gear, a driving rod, a first gear, a second gear, a sleeve and a fixing screw. The driving rack is connected to the reinforcing frame. The driving gear is sleeved on the driving rod. The driving rod is arranged at an angle with the horizontal direction. The driving rod is rotatably connected to the box body. The first gear is sleeved on the driving rod. The second gear is sleeved on the sleeve. The sleeve is rotatably connected to the box body. The second gear meshes with the first gear. The fixing screw passes through the sleeve and the box body. The fixing screw is threadedly connected to the sleeve. A threaded groove is formed on the mounting base plate. The fixing screw extends into the threaded groove to fix the box body and the mounting base plate.

[0006] By adopting the above technical solution, first pass the mounting base plate at the bottom end of the column through the bridge guardrail and place it well; then place the box body outside the bridge guardrail so that the bottom of the box body abuts against the top of the mounting base plate; finally connect the reinforcing frame to the middle section of the column and let the reinforcing frame pass through the bridge guardrail and the insertion hole on the side wall of the box body. When the reinforcing frame passes through the insertion hole, the driving rack connected thereto will drive the cooperating driving gear to rotate. Since the driving gear is sleeved on the driving rod, the driving rod rotates, and then drives the first gear sleeved on the driving rod to rotate. The first gear drives the second gear that meshes with it and is sleeved on the sleeve to rotate, causing the sleeve to rotate. Since the fixing screw is threadedly connected to the sleeve, the fixing screw passes through the sleeve and the box body under the rotation of the sleeve and extends into the threaded groove of the mounting base plate, finally realizing the fixation of the box body and the mounting base plate, enhancing the overall stability of the railway communication column. This device can neither damage the ground nor achieve the quick and simple installation of the communication column.

[0007] Preferably, the reinforcing frame includes a first connecting portion, a second connecting portion and a fixing portion. The first connecting portion and the second connecting portion are respectively arranged at both ends of the fixing portion and are both connected to the fixing portion. A limiting space is formed among the first connecting portion, the second connecting portion and the fixing portion. The column body is arranged in the limiting space. The fixing portion is connected to the side wall of the column body far from the bridge. The first connecting portion and the second connecting portion both pass through the bridge guardrail and are inserted into the box body.

[0008] By adopting the above technical solution, a more stable connection structure can be established between the column body and the box body through the reinforcing frame. The first connecting portion and the second connecting portion of the reinforcing frame are respectively inserted into the box body from both sides of the column body, increasing the connection area and stability, and can better disperse the external force received by the column body to the box body and the mounting base plate, improving the overall firmness and stability of the railway communication column.

[0009] Preferably, a bolt is threadedly connected to the fixing portion, and the bolt is threadedly connected to the column body.

[0010] By adopting the above technical solution, the fixing part of the column body of the communication column and the reinforcement frame are connected by bolts in a threaded manner, enabling the reinforcement frame to be firmly connected to the column body, enhancing the support stability of the reinforcement frame for the column body, and contributing to improving the structural stability of the entire railway communication column.

[0011] Preferably, the box body is provided with insertion holes. There are two insertion holes. The first connection part and the second connection part each pass through one insertion hole, and the insertion holes match the corresponding connection parts.

[0012] By adopting the above technical solution, the two insertion holes matching the corresponding connection parts are for the first connection part and the second connection part to pass through, which can make the connection between the reinforcement frame and the box body more stable and enhance the overall structural stability. At the same time, this matching setting can reduce the possibility of external impurities entering the interior of the box body through the insertion holes, playing a protective role for the components inside the box body.

[0013] Preferably, driving racks are semi-embedded on the side walls of the first connection part and the second connection part that are close to each other, and the end walls of the driving racks are flush with the end walls of the corresponding connection parts.

[0014] By adopting the above technical solution, the driving racks are semi-embedded on the side walls of the first connection part and the second connection part that are close to each other, which can not only ensure the stable setting of the driving racks on the connection parts, but also enable the connection parts to block the insertion holes when inserted into the insertion holes of the box body, reducing the possibility of external dust, moisture, etc. entering the interior of the box body and affecting the normal operation of components such as the fixing components inside the box body. At the same time, one end of the driving rack is flush with the end wall of the corresponding connection part, which can make the driving rack better cooperate with the driving gear inside the box body to achieve power transmission.

[0015] Preferably, a limiting block is connected to the top of the mounting base plate, a limiting hole is opened at the bottom of the box body, and the limiting hole communicates with the interior of the box body. When the box body is connected to the top of the mounting base plate, the limiting block is inserted into the limiting hole.

[0016] By adopting the above technical solution, when the mounting base plate at the bottom end of the column body abuts against the bottom of the box body, the limiting block on the top of the mounting base plate can be inserted into the limiting hole at the bottom of the box body to achieve preliminary positioning between the box body and the mounting base plate, ensuring the accuracy of their positions and facilitating subsequent fixing operations.

[0017] Preferably, a first placement groove is opened on the mounting base plate, the limiting block is arranged in the first placement groove and is slidably connected to the mounting base plate. A regulating screw is rotatably connected to the bottom of the limiting block, the regulating screw passes through the mounting base plate and extends to the outside, and the regulating screw is threadedly connected to the mounting base plate.

[0018] By adopting the above technical solution, during use, when the adjusting screw is rotated, since the adjusting screw is threadedly connected to the mounting base plate, the adjusting screw will drive the limiting block to slide relative to the mounting base plate in the first placement groove, and the position of the limiting block can be flexibly adjusted according to actual needs, achieving precise limitation of the components cooperating with it, and enhancing the stability and adaptability of the overall structure.

[0019] Preferably, a second placement groove and a communication groove are formed at the top of the mounting base plate. The communication groove is arranged between the first placement groove and the second placement groove and communicates the first placement groove and the second placement groove. A pressing block is arranged in the second placement groove. The pressing block is connected with a synchronous rod. The synchronous rod passes through the communication groove and is connected with the limiting block. A reinforcing hole is formed at the bottom of the box body. The bottom of the sleeve passes through the reinforcing hole. When the pressing block extends into the reinforcing hole and abuts against the bottom of the sleeve, it is used to reinforce the position of the sleeve.

[0020] By adopting the above technical solution, when the limiting block slides in the first placement groove, the synchronous rod drives the pressing block to move in the second placement groove. The reinforcing hole at the bottom of the box body corresponds to the second placement groove. After the box body and the mounting base plate are fixed by the fixing screw, the adjusting screw is rotated again, so that the limiting block drives the pressing block to move. The pressing block can extend into the reinforcing hole and abut against the bottom of the sleeve, effectively reinforcing the position of the sleeve, enhancing the connection stability between the box body and the mounting base plate, and further reinforcing the structure of the railway communication post.

[0021] Preferably, a handle is connected to the end of the adjusting screw located outside.

[0022] By adopting the above technical solution, the handle facilitates the operator to rotate the adjusting screw, thereby adjusting the position of the limiting block.

[0023] Preferably, a surrounding plate is connected to the bottom of the mounting base plate, and the surrounding plate semi - surrounds the handle.

[0024] By adopting the above technical solution, the surrounding plate can provide certain protection to the handle during operation, reducing the possibility of being affected by external collision or foreign object interference and affecting the adjustment operation.

[0025] In summary, the present invention has the following beneficial effects: First, pass the installation base plate at the bottom end of the column through the bridge guardrail and place it properly; then place the box body outside the bridge guardrail so that the bottom of the box body abuts against the top of the installation base plate; finally, connect the reinforcement frame to the middle section of the column, and let the reinforcement frame pass through the bridge guardrail and the jack on the side wall of the box body. When the reinforcement frame passes through the jack, the driving rack connected to it will drive the cooperating driving gear to rotate. Since the driving gear is sleeved on the driving rod, the driving rod will rotate, and then drive the first gear sleeved on the driving rod to rotate. The first gear drives the second gear that meshes with it and is sleeved on the sleeve to rotate, causing the sleeve to rotate. Since the fixing screw is threadedly connected to the sleeve, the fixing screw passes through the sleeve and the box body under the rotation of the sleeve and extends into the thread groove of the installation base plate, finally realizing the fixation of the box body and the installation base plate, enhancing the overall stability of the communication column for railways. This device neither damages the ground nor is convenient for the installation of the communication column. BRIEF DESCRIPTION OF THE DRAWINGS
