Description

Technical Field

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

[0002] In the field of railway communications, with the continuous expansion of the railway transportation network and the continued growth of transportation demand, reliable communication equipment is crucial for ensuring safe railway operations and efficient dispatching. Numerous communication facilities are required along railway lines to ensure the timely transmission of information and communication. As a key component of railway communication systems, communication poles provide railway personnel with convenient communication channels, allowing them to contact the dispatch center or other departments at any time along the line. This plays an indispensable role in handling emergencies, coordinating transportation operations, and ensuring the normal operation of trains. Furthermore, with the diversification of railway construction, including the increase in special sections such as bridges, higher requirements are being placed on the installation and use of communication poles in various environments.

[0003] In the past, railway communication poles were mostly installed using a simple fixing method. A common practice is to connect the pole to the mounting base by welding. This method can ensure the stability of the pole to a certain extent, but it is more complicated during installation and inconvenient for subsequent maintenance and replacement. Another method is to use ordinary bolts for fixing. This is done by drilling holes in the mounting base, inserting the bolts, and tightening them. However, in some special locations, such as when used on bridges, damage to the bridge ground is prohibited in order to protect the structural integrity of the bridge ground. Therefore, there is an urgent need to develop a communication pole that can be installed quickly and efficiently. Summary of the Invention

[0004] In order to realize the quick and easy installation of a communication pole, the present invention provides a communication pole for railways.

[0005] The present invention provides a railway communication column adopting the following technical solutions:

[0006] A railway communication column comprises a column body, wherein the bottom end of the column body is fixedly connected to a mounting base plate, and the mounting base plate passes through a bridge guardrail;

[0007] A box body is arranged outside the bridge guardrail, and the bottom of the box body is connected to the top of the installation base plate;

[0008] A reinforcement frame connected to the middle section of the column, passing through the bridge guardrail and inserted into the box body;

[0009] A fixing assembly is arranged inside the box body, and the fixing assembly 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 reinforcement frame, the driving gear is sleeved on the driving rod, and the driving rod is set at an angle to 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 is meshed with the first gear, the fixing screw passes through the sleeve and the box body, and the fixing screw is threadedly connected to the sleeve. A threaded groove is provided on the mounting base plate, and the fixing screw extends into the threaded groove to achieve fixation of the box body and the mounting base plate.

[0010] By adopting the above technical solution, the mounting base plate at the bottom of the column is first passed through the bridge guardrail and installed. The box body is then placed outside the bridge guardrail, with the bottom of the box body abutting against the top of the mounting base plate. Finally, the reinforcement frame is connected to the middle section of the column body, allowing the reinforcement frame to pass through the sockets in the bridge guardrail and the side wall of the box body. Once the reinforcement frame passes through the sockets, the drive rack connected to it drives the mating drive gear to rotate. Since the drive gear is mounted on the drive rod, the drive rod rotates, which in turn drives the first gear mounted on the drive rod. The first gear in turn drives the second gear meshing with it and mounted on the sleeve, 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 as the sleeve rotates, and extends into the threaded groove of the mounting base plate, ultimately securing the box body to the mounting base plate and enhancing the overall stability of the railway communication column. This device does not damage the ground and allows for quick and easy installation of the communication column.

[0011] Preferably, the reinforcement frame includes a first connecting part, a second connecting part and a fixed part, the first connecting part and the second connecting part are respectively arranged at both ends of the fixed part, and are both connected to the fixed part, a limited space is enclosed between the first connecting part, the second connecting part and the fixed part, the column is arranged in the limited space, the fixed part is connected to the side wall of the column away from the bridge, and the first connecting part and the second connecting part both pass through the bridge guardrail and are inserted into the box body.

[0012] By adopting the above technical solution, a more stable connection structure can be established between the column and the box body through the reinforcement frame. The first connection part and the second connection part of the reinforcement frame are respectively inserted into the box body from both sides of the column, thereby increasing the connection area and stability, and can better disperse the external force applied to the column to the box body and the installation base plate, thereby improving the overall firmness and stability of the railway communication column.

[0013] Preferably, the fixing portion is threadedly connected with a bolt, and the bolt is threadedly connected to the column.

[0014] By adopting the above technical solution, the column body of the communication column and the fixing part of the reinforcement frame are connected by bolt threads, so that the reinforcement frame can be firmly connected to the column body, thereby enhancing the support stability of the reinforcement frame on the column body and helping to improve the structural stability of the entire railway communication column.

[0015] Preferably, the box body is provided with two sockets, the first connecting portion and the second connecting portion each pass through one socket, and the sockets match the corresponding connecting portions.

[0016] By adopting the above technical solution, two sockets matching the corresponding connecting parts are used for the first connecting part and the second connecting part to pass through, which can make the connection between the reinforcement frame and the box body more stable and enhance the stability of the overall structure; at the same time, this matching setting can reduce the possibility of external impurities entering the interior of the box body through the sockets, thereby protecting the internal components of the box body.

[0017] Preferably, the side walls of the first connecting portion and the second connecting portion that are close to each other are both half-inlaid with a driving rack, and the end wall of the driving rack is flush with the end wall of the corresponding connecting portion.

[0018] By adopting the above technical solution, the side walls of the first connecting part and the second connecting part that are close to each other are half-embedded with the driving rack, which not only ensures that the driving rack is firmly set on the connecting part, but also enables the connecting part to block the insertion hole when inserted into the box body, thereby reducing the possibility of external dust, moisture, etc. entering the interior of the box body through the insertion hole and affecting the normal operation of parts such as the fixed components inside the box body. At the same time, one end of the driving rack is flush with the end wall of the corresponding connecting part, which can enable the driving rack to better cooperate with the driving gear in the box body to achieve power transmission.

[0019] Preferably, a limiting block is connected to the top of the mounting base, a limiting hole is opened at the bottom of the box body, the limiting hole is connected to the interior of the box body, and when the box body is connected to the top of the mounting base, the limiting block is inserted into the limiting hole.

[0020] By adopting the above technical solution, when the mounting base plate at the bottom end of the column abuts against the bottom of the box body, the limit block on the top of the mounting base plate can be inserted into the limit hole at the bottom of the box body, thereby realizing the preliminary positioning between the box body and the mounting base plate, ensuring the accuracy of the positions of the two, and facilitating subsequent fixing operations.

[0021] Preferably, a first placement groove is provided on the mounting base, the limit block is provided in the first placement groove and is slidingly connected to the mounting base, the bottom of the limit block is rotatably connected to an adjusting screw, the adjusting screw passes through the mounting base and extends to the outside, and the adjusting screw is threadedly connected to the mounting base.

[0022] By adopting the above technical solution, when in use, the adjusting screw is rotated. Since the adjusting screw is threadedly connected to the mounting base, the adjusting screw will drive the limit block to slide relative to the mounting base in the first placement groove. The position of the limit block can be flexibly adjusted according to actual needs to achieve precise limiting of the components that cooperate with it, thereby enhancing the stability and adaptability of the overall structure.

[0023] Preferably, a second placement groove and a connecting groove are provided on the top of the mounting base, the connecting groove is provided between the first placement groove and the second placement groove, and connects the first placement groove and the second placement groove; a tightening block is provided in the second placement groove, the tightening block is connected to a synchronization rod, and the synchronization rod passes through the connecting groove and is connected to the limit block; a reinforcement hole is provided at the bottom of the box body, the bottom of the sleeve passes through the reinforcement hole, the tightening block extends into the reinforcement hole, and when it abuts against the bottom of the sleeve, it is used to achieve reinforcement of the sleeve position.

[0024] By adopting this technical solution, as the limit block slides within the first placement slot, the synchronization rod drives the abutment block to move within the second placement slot. The reinforcement hole at the bottom of the box body corresponds to the second placement slot. After the fixing screw secures the box body to the mounting base, the adjustment screw is rotated, causing the limit block to drive the abutment block to move. The abutment block can then extend into the reinforcement hole and abut against the bottom of the sleeve, effectively reinforcing the sleeve's position, enhancing the stability of the connection between the box body and the mounting base, and further strengthening the railway communication column structure.

[0025] Preferably, the end of the adjusting screw located outside is connected to a handle.

[0026] By adopting the above technical solution, the handle makes it convenient for the operator to rotate the adjustment screw to adjust the position of the limit block.

[0027] Preferably, a panel is connected to the bottom of the mounting base, and the panel half surrounds the handle.

[0028] By adopting the above technical solution, the enclosure can provide a certain degree of protection to the handle when operating it, reducing the possibility of the adjustment operation being affected by external collisions or interference from foreign objects.

[0029] In summary, the present invention has the following beneficial effects:

[0030] First, insert the mounting plate at the bottom of the column through the bridge guardrail and secure it. Then, place the box body outside the bridge guardrail, so that the bottom of the box body abuts the top of the mounting plate. Finally, connect the reinforcement frame to the middle section of the column body and pass the reinforcement frame through the holes in the bridge guardrail and the side wall of the box body. Once the reinforcement frame passes through the hole, the drive rack connected to it drives the mating drive gear to rotate. Since the drive gear is mounted on the drive rod, the drive rod rotates, which in turn drives the first gear mounted on the drive rod. The first gear in turn drives the second gear meshing with it and mounted on the sleeve, 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 as the sleeve rotates, and extends into the threaded groove of the mounting plate, ultimately securing the box body to the mounting plate and enhancing the overall stability of the railway communication column. This device does not damage the ground and facilitates the installation of the communication column. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Reference Figure 3The side wall of the box body 5 is provided with a socket 51, and two sockets 51 are provided, one corresponding to the first connecting portion 71 and the second connecting portion 72. The first connecting portion 71 and the second connecting portion 72 pass through the bridge guardrail 4 and are inserted into the corresponding sockets 51.

[0052] Reference Figure 2 and Figure 3 The fixing assembly 6 is symmetrically arranged in two groups. The fixing assembly 6 includes a drive rack 61, a drive gear 62, a drive rod 63, a first gear 64, a second gear 65, a sleeve 66, and a fixing screw 67. The drive rack 61 is semi-inlaid on the side walls of the first connecting portion 71 and the second connecting portion 72 adjacent to each other, and the end wall of the drive rack 61 is flush with the end wall of the corresponding connecting portion.

[0053] Reference Figure 2 and Figure 3 The drive gear 62 is mounted on a vertically disposed drive rod 63, with both ends of the drive rod 63 being rotatably connected to the housing 5. A first gear 64 is mounted on the bottom end of the drive rod 63, and a second gear 65 is mounted on a sleeve 66, which is rotatably connected to the bottom of the housing 5. The second gear 65 meshes with the first gear 64. A fixing screw 67 passes through the sleeve 66 and is threadedly connected to the sleeve 66.

[0054] Reference Figure 4 The bottom of the box body 5 is provided with a through hole 52, the axis of which coincides with the axis of the sleeve 66. The mounting base 3 is provided with a threaded groove 31, which corresponds to the through hole 52. A fixing screw 67 passes through the through hole 52 and extends into the threaded groove 31. The fixing screw 67 is threadedly connected to the mounting base 3 to secure the box body 5 to the mounting base 3.

[0055] After the first connecting portion 71 and the second connecting portion 72 of the reinforcement frame 7 pass through their respective corresponding jacks 51, the driving rack 61 connected thereto will drive the driving gear 62 matched therewith to rotate, and the driving gear 62 will drive the driving rod 63 to rotate, thereby driving the first gear 64 sleeved on the driving rod 63 to rotate, and the first gear 64 will drive the second gear 65 to rotate, and the second gear 65 will cause the sleeve 66 to rotate. The fixing screw 67 passes through the sleeve 66 and the box body 5 under the rotation of the sleeve 66, and extends into the threaded groove 31 of the mounting base 3, thereby finally achieving the fixation of the box body 5 and the mounting base 3.

[0056] Reference Figure 4 The mounting base 3 is provided with a second placement groove 33 and a connecting groove 34. One end of the connecting groove 34 is connected to the second placement groove 33, and the other end is connected to the first placement groove 32. A tightening block 9 is provided in the second placement groove 33. The tightening block 9 is fixedly connected to a synchronization rod 91. The synchronization rod 91 passes through the connecting groove 34 and is fixedly connected to the limit block 8.

[0057] Reference Figure 4 The box body 5 is provided with a reinforcement hole 54 corresponding to the second placement slot 33. A rotating disk 661 is fixedly connected to the bottom of the sleeve 66. The rotating disk 661 passes through the reinforcement hole 54 and is rotatably connected to the mounting base 3. The tightening block 9 is inserted into the reinforcement hole 54 and abuts against the rotating disk 661, thereby securing the rotating disk 661.

[0058] When the limit block 8 slides in the first placement slot 32, it drives the abutting block 9 to move in the second placement slot 33 via the synchronization rod 91. The reinforcement hole 54 at the bottom of the box body 5 corresponds to the second placement slot 33. After the fixing screw 67 secures the box body 5 to the mounting base 3, the adjusting screw 81 is rotated, causing the limit block 8 to drive the abutting block 9 to move. The abutting block 9 can extend into the reinforcement hole 54 and abut against the bottom of the sleeve 66, effectively reinforcing the position of the sleeve 66, enhancing the stability of the connection between the box body 5 and the mounting base 3, and further strengthening the structure of the railway communication column.

[0059] The usage principle of this application is as follows: first, pass the mounting base plate 3 at the bottom end of the column 1 through the bridge guardrail 4 and place it, hold the handle 82 and rotate the adjusting screw 81 to make the limit block 8 protrude from the mounting base plate 3; then place the box body 5 on the outside of the bridge guardrail 4, place the bottom of the box body 5 on the top of the mounting base plate 3, and insert the limit block 8 into the limit hole 53; then pass the connecting part of the reinforcement frame 7 through the bridge and insert it into the box body 5. At this time, the column 1 is stuck in the limit space of the reinforcement frame 7.

[0060] After the first and second connecting portions 71 and 72 of the reinforcement frame 7 pass through their respective corresponding receptacles 51, the drive rack 61 connected thereto drives the mating drive gear 62 to rotate. The drive gear 62 drives the drive rod 63 to rotate, which in turn drives the first gear 64 mounted on the drive rod 63 to rotate. The first gear 64 drives the second gear 65 to rotate, and the second gear 65 rotates the sleeve 66. As the sleeve 66 rotates, the fixing screw 67 passes through the sleeve 66 and the box body 5 and extends into the threaded groove 31 of the mounting base 3, thereby securing the box body 5 to the mounting base 3. The adjusting screw 81 is then rotated, causing the limit block 8 to drive the abutment block 9 to move. The abutment block 9 can extend into the reinforcement hole 54 and abut against the bottom of the sleeve 66, effectively reinforcing the position of the sleeve 66, enhancing the stability of the connection between the box body 5 and the mounting base 3, and further strengthening the structure of the railway telephone post. This device does not damage the ground and allows for quick and easy installation of the telephone post.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
