Description

Technical Field

[0001] The utility model relates to the technical field of railway tunnel construction, in particular to a track pipe installation and positioning tool. Background Art

[0002] At present, tunnel construction is an important part of railway construction. Railway tunnels are generally designed with special caverns, repeater caverns, disconnector caverns, lighting box transformer caverns, etc. Pre-buried track pipes are designed between each cavern, at the intersection of permanent auxiliary tunnels and main tunnels, and at the entrance and exit of the tunnel. The track pipe is used to avoid cable dead wires and keep the signal unobstructed.

[0003] During the construction process, there are strict requirements for the net spacing of the rail tubes, so positioning tools are needed during installation. However, the existing positioning tools can only simply limit the rail tubes, and cannot protect the exposed parts of the rail tubes. It is easy for external debris or concrete to enter the rail tubes, causing the rail tubes to be blocked, affecting the later cable layout. If the rail tubes are seriously blocked or even damaged, they must be reworked, which has a serious impact on the cost, quality and progress of the construction. Utility Model Content

[0025] In this embodiment, the positioning box 1 is a prism structure. Specifically, the positioning side plate 3 and the positioning baffle plate 5 are both triangular prism structures, the sides of the positioning side plate 3 and the positioning baffle plate 5 are connected to the sides of the nozzle protection plate 4, and the bottom of the nozzle protection plate 4 is connected to the positioning bottom plate 2.

[0026] In this embodiment, the top end of the pipe mouth protection plate 4 is higher than the top ends of the positioning side plate 3 and the positioning partition plate 5 .

[0027] Preferably, the positioning bottom plate 2, the positioning side plate 3, the nozzle protection plate 4 and the positioning baffle 5 are all made of steel plates. The bottoms of the positioning side plates 3, the nozzle protection plate 4 and the positioning baffle 5 are welded to the positioning bottom plate 2, and the sides of the positioning side plates 3 and the positioning baffle 5 are welded to the sides of the nozzle protection plate 4.

[0028] The rail pipe installation positioning tool of this embodiment is adopted, and a positioning box 1 with a front end opening is composed of a positioning bottom plate 2, a positioning side plate 3 and a pipe mouth protection plate 4, and a plurality of positioning partitions 5 are arranged on the bottom plate of the positioning box 1, which can not only position the rail pipe and effectively control the pipe spacing of the rail pipe, but also protect the end of the rail pipe to prevent the hole from entering concrete or other debris.

[0029] Example 2

[0030] Combination Figures 3 to 6 This embodiment provides another structure of rail tube installation positioning tooling, which is different from Embodiment 1 in that the spacing between the positioning partitions 5 is adjustable.

[0031] In this embodiment, at least one of the positioning baffles 5 is slidably disposed in a slide groove 6 on the top of the positioning bottom plate 2 , and a side portion of the positioning baffle 5 abuts against a side portion of the pipe mouth protection plate 4 .

[0032] Preferably, a groove 51 is provided at the bottom of the positioning partition 5, a first spring 52 is fixedly arranged in the groove 51, a first wedge block 53 is connected to the end of the first spring 52, a second wedge block 61 and a third wedge block 62 are arranged in the slide groove 6, a first limiting groove 7 is formed between the inclined surface of the second wedge block 61 and the inner wall at one end of the slide groove 6, a second limiting groove 8 is formed between the inclined surface of the third wedge block 62 and the vertical surface of the second wedge block 61, the sizes of the first limiting groove 7 and the second limiting groove 8 are matched with the size of the first wedge block 53, a second spring 63 is connected between the third wedge block 62 and the inner wall at one end of the slide groove 6, and the third wedge block 62 is slidably arranged in the slide groove 6. Specifically, the top surface height of the third wedge block 62 is higher than the top surface height of the second wedge block 61.

[0033] Taking the first positioning partition 5 on the left as an example, when in use, the initial position of the positioning partition 5 is in the first limiting groove 7. When the positioning partition 5 needs to be adjusted, it slides to the left (the side close to the positioning side plate 3). During the sliding process, the first wedge block 53 compresses the first spring 52 under the action of the second wedge block 61, and after passing through the second wedge block 61, it enters the second limiting groove 8 to complete the adjustment of the positioning partition 5. When it is necessary to adjust the positioning baffle 5 to its original position, the positioning baffle 5 is first moved to the left. At this time, the first wedge block 53 at the bottom of the positioning baffle 5 interacts with the third wedge block 62, and the first spring 52 and the second spring 63 are both compressed. When the first wedge block 53 passes the top surface of the third wedge block 62, the first spring 52 gradually extends to make the first wedge block 53 abut against the inclined surface of the third wedge block 62 close to one end of the second spring 63, and then the positioning baffle 5 is quickly moved to the right. During this process, the second spring 63 gradually extends until the third wedge block 62 contacts the second wedge block 61, and the first wedge block 53 quickly passes through the top surfaces of the third wedge block 62 and the second wedge block 61, and finally the first wedge block 53 returns to the first limiting groove 7. During this process, the second spring 63 retracts to its original position, so that the third wedge block 62 is reset.

[0034] By adopting this solution, the distance between the positioning partitions 5 can be adjusted, so that the rail pipes with different diameters can be positioned.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
