Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel engineering construction, relates to the field of installation of track-crossing pipes, and particularly relates to an installation protection device for track-crossing pipes. Background Technique

[0002] In the railway construction system, tunnel construction is a key link. In railway tunnels, various special chambers such as disconnector chambers and lighting box transformer chambers are planned. According to the design specifications, track-crossing pipes need to be pre-embedded at specific positions such as between chambers, intersections of permanent auxiliary galleries and main tunnels, and tunnel entrances and exits. Track-crossing pipes play an important role in the railway communication and power systems. They can effectively prevent the problem of dead wires when cables are threaded, ensure smooth signal transmission, and are the basic guarantee for maintaining the stable operation of the system.

[0003] The installation of track-crossing pipes has extremely high precision requirements for the net spacing. During construction, positioning tooling is needed to ensure the installation precision. However, most of the positioning tooling on the market currently has a single function and can only achieve simple limiting of track-crossing pipes, and it is difficult to protect the exposed parts of track-crossing pipes. The tunnel construction environment is complex, concrete pouring operations are frequent, and sundries often fall. The exposed parts of track-crossing pipes are extremely vulnerable to external interference. Once sundries or concrete enter the interior of the track-crossing pipes, it may cause blockage of the track-crossing pipes. This will not only bring great difficulties to the subsequent cable threading work and seriously affect the construction efficiency; at the same time, if the track-crossing pipes are severely blocked or damaged, rework is required. Rework will not only greatly increase the construction cost and delay the construction progress, but also have a negative impact on the overall quality of the project, and may cause problems such as unstable communication signals and power transmission failures.

[0004] In addition, there are other drawbacks in the traditional installation method of track-crossing pipes. Before burying track-crossing pipes, some construction workers do not use accurate measurement data for positioning, and the operation is highly random, which not only causes material waste but also may lead to too many joints of track-crossing pipes, increasing potential faults.

[0005] In view of the problems of insufficient positioning accuracy and lack of protection in the installation process of track-crossing pipes in railway tunnels, it is extremely urgent to develop an installation positioning protection device that can not only improve the positioning accuracy of track-crossing pipes but also have a reliable protection function. The development of this device has important practical significance for improving the installation quality of track-crossing pipes, ensuring the level of railway engineering construction, and reducing the later maintenance cost.

[0006] The present invention proposes an installation positioning protection device for track-crossing pipes in view of the above background. Summary of the Invention

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a positioning and protection device for the installation of rail pipes, which solves the technical problems of insufficient positioning accuracy and inability to effectively protect the rail pipes before and after concrete pouring in the prior art.

The housing has windows in the middle of its upper and lower surfaces. Several sets of movable track pipe protection components are provided at the bottom of the housing along its length. Each set of track pipe protection components includes two track pipe positioning plates symmetrically arranged about the horizontal center line of the housing. One end of the two track pipe positioning plates is in contact with each other, and the other end is connected to the bottom of the housing through a movable component.

[0012] Preferably, in any of the above embodiments, each group of moving components includes two first guide sleeves, which are fixedly connected to both ends of the bottom of the housing, and a guide rod is connected between the two first guide sleeves.

[0013] In any of the above embodiments, it is preferred that each of the track tube positioning plates is fixedly connected to one end of the housing with two second guide sleeves, which are sleeved on the guide rod.

[0014] In any of the above embodiments, it is preferred that each of the rail guide positioning plates is fixedly connected to two third guide sleeves, the two third guide sleeves are fixedly connected to the two sides of the semicircular opening of the rail guide positioning plate, and the two third guide sleeves are connected to each other by a U-shaped buckle.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please see Figures 1 to 2 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0025] Please see Figure 1-2This utility model provides a track pipe installation positioning protection device, including a housing 1. The housing 1 has windows in the middle of the upper and lower surfaces. The bottom of the housing 1 is provided with several sets of movable track pipe protection components along its length. Each set of track pipe protection components includes two track pipe positioning plates 2 symmetrically arranged about the horizontal center line of the housing 1. One end of the two track pipe positioning plates 2 is in contact with each other, and the other end is connected to the bottom of the housing 1 through a moving component. The contact ends of the two track pipe positioning plates 2 are symmetrically opened with semi-circular openings to form track pipe positioning ports 3.

[0026] In this embodiment, the track pipe installation positioning and protection device includes a housing 1 for peripheral maintenance. The housing 1 has an inverted trapezoidal structure and is composed of four trapezoidal steel plates and two rectangular steel plates with windows in the middle. The windows are located on the upper and lower end faces of the housing 1 to facilitate the entry of the track pipe into the housing 1 for positioning and protection.

[0027] The housing 1 contains three sets of positioning and protection structures for the rail tubes. Each set of positioning and protection structures includes two opposing rail tube positioning plates 2. One end of the two rail tube positioning plates 2 is in contact with each other, and two semi-circular openings are cut at the contact end with the center of the butt joint edge of the two steel plates as the center. The two semi-circular openings form a rail tube positioning opening 3 to position the rail tube. The other end of the two rail tube positioning plates 2 is movably connected to the bottom of the housing 1 via a movable component, which facilitates the adjustment of the spacing between adjacent sets of positioning and protection components, thereby ensuring that the minimum spacing requirement between adjacent rail tubes is met and facilitating precise control of the minimum spacing between rail tubes.

[0028] In this embodiment, the diameter of the guide tube positioning port 3 is 1mm larger than the outer diameter of the guide tube, which facilitates the passage and positioning of the guide tube and prevents it from wobbling within the guide tube positioning port 3. Of course, the diameter of the guide tube positioning port 3 is not limited to being 1mm larger than the diameter of the guide tube. Other dimensions that can position the guide tube and effectively prevent it from wobbling within the guide tube positioning port 3 are also acceptable. For example, the diameter of the guide tube positioning port 3 can be 1.5mm or 2mm larger than the outer diameter of the guide tube, etc., and can be selected according to the actual construction conditions.

[0029] After the track pipe is installed and positioned, the minimum spacing between adjacent track pipes meets the requirements. Covering the shell 1 with a steel plate or wooden template is sufficient to protect the track pipe during concrete pouring and concrete curing. This effectively prevents debris or concrete from entering the track pipe and causing blockage, thereby reducing the difficulty of subsequent cable installation, improving construction efficiency, ensuring construction quality, and reducing construction costs.

[0030] In this embodiment, the top of the housing 1 is provided with two first lifting lugs 4, which facilitates the installation of the device at a suitable position and elevation.

[0031] In actual operation, gaps may appear between two adjacent track tube positioning plates 2. We usually use cut wooden templates to fill the gaps and set four second lifting lugs 5 along the length of the two inner sides of the shell 1. The second lifting lugs 5 provide support points to fix the wooden templates.

[0032] As a further description of the above embodiment, after the guide tube enters the guide tube positioning port 3, the two guide tube positioning plates 2 need to be locked to ensure the stability of the guide tube positioning. The specific locking structure is as follows:

[0033] Two third guide sleeves 10 are symmetrically welded on both sides of the semi-circular opening of each rail pipe positioning plate 2, and U-shaped buckles 11 with circular cross sections are inserted between two adjacent third guide sleeves 10 on the two rail pipe positioning plates 2.

[0034] Of course, the locking method between the two rail tube positioning plates 2 in the same group is not limited to using U-shaped buckles 11 for connection. Other connection methods that can achieve detachable connection between the two are also acceptable. For example, two threaded sleeves (not shown in the figure) are symmetrically welded on both sides of the semi-circular opening of each rail tube positioning plate 2. Screws (not shown in the figure) are inserted between two adjacent threaded sleeves on the two rail tube positioning plates 2 respectively, and then connected and fixed by nuts.

[0035] As a further description of the above embodiment, the track tube positioning plate 2 moves at the bottom of the housing 1, thereby facilitating the achievement of the minimum spacing requirement between two adjacent track tube positioning plates 2. The moving component includes two first guide sleeves 8, which are fixedly connected to the two ends of the bottom of the housing 1, and a guide rod 7 is connected between the two first guide sleeves 8.

[0036] Meanwhile, two second guide sleeves 9 are welded to one end of each rail tube positioning plate 2 that is connected to the housing 1. The second guide sleeves 9 are fitted onto the guide rod 7, which facilitates movement along the length of the guide rod 7, thereby enabling precise adjustment of the distance between two adjacent rail tube positioning plates 2.

[0037] In this embodiment, each of the track tube positioning plates 2 is fixedly connected with a third lifting lug 6, which facilitates manual opening of the track tube positioning plate 2.

[0038] In the above embodiments, the first guide sleeve 8, the second guide sleeve 9, and the third guide sleeve 10 are all made from steel plates or steel plate scraps discarded at the construction site.

[0039] In summary, the working principle of the track pipe installation positioning protection device is as follows:

[0040] During use, first place the housing 1 in a suitable position and adjust it to a suitable elevation. Then, open the two rail tube positioning plates 2 of the same circle in the upward direction and adjust them to the position of the rail tube along the guide rod 7. Use the circular notch to lock the rail tube. Then, insert the U-shaped buckle 11 into the third guide sleeve 10 to lock the rail positioning plate 2. Repeat the above operation for the rail tube positioning plates 2 of the remaining two rail tubes.

[0041] The adjacent rail guide positioning plates 2 are set according to the minimum spacing requirement. In actual operation, gaps will appear between adjacent rail guide positioning plates 2. The gaps are filled by cutting wooden templates and using the second lifting lug 5 to provide a support point to fix the wooden templates.

[0042] Once the track pipe installation and positioning device is installed and the minimum spacing between adjacent track pipes meets the requirements, covering it with a steel plate or wooden template will provide protection for the track pipes during concrete pouring and curing.

[0043] In summary, this utility model can reliably and safely position and protect the rail-crossing pipes, protect the exposed parts of the rail-crossing pipes, and precisely control the minimum spacing between rail-crossing pipes. This achieves the effects of improving the installation quality of rail-crossing pipes, increasing construction efficiency, and ensuring the level of railway engineering construction. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
