Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction auxiliary devices, and particularly to a construction auxiliary equipment for rail transit engineering. Background Art

[0002] At present, with the booming development of modern rail transit engineering, rail laying, as a crucial basic link, is directly related to the stability, safety and operation comfort of the entire rail transit system.

[0003] However, in the existing rail laying, after the rail is initially placed on the pre-treated roadbed foundation, only simple tools (such as hammers, crowbars, etc.) are often relied on by manual labor for rough adjustment and compaction operations. On the one hand, the manual hammering force is limited and uneven, making it difficult to ensure a tight and stable fit between the rail and the roadbed. This makes the rail extremely prone to loosening and displacement under the long-term action of train loads in the follow-up, not only increasing the frequency and cost of daily rail maintenance, but more seriously, it may cause deformation of the rail geometric dimensions, threatening the safety of train operation. For example, in high-speed sections, even a tiny rail displacement deviation may lead to train derailment accidents. On the other hand, the manual operation efficiency is extremely low. Especially in large-scale rail laying projects, it consumes a large amount of human and time costs, and the manual operation difficulty is further increased, making it more difficult to control the rail installation accuracy.

[0004] In view of the many disadvantages of the traditional rail laying method in the auxiliary hammering and compaction link, there is an urgent need for a construction auxiliary equipment for rail transit engineering that can efficiently assist in hammering and compacting the rail during the rail laying and installation process.

In this way, the first hammer compaction head moves up and down to assist in hammering the track being laid, so that the track can be more tightly compacted after laying. 2. In the present invention, when the motor works, it also drives the first sprocket to rotate through the output shaft. The first sprocket drives the rotating shaft and the double cam to rotate through the chain transmission with the second sprocket. During the rotation of the double cam, the two cams and the balls alternately roll and contact with the movable plate. Furthermore, the movable plate and the swing rod can rotate up and down around the swing shaft as the center. At the same time, the return spring plays a role of stretching and resetting. The swing rod also drives the movable seat to move left and right through the return connecting rod and is reset in cooperation with the first return spring and the second return spring. Thus, the swing rod can perform reciprocating rotational swinging. When the swing rod swings, it drives the second hammer compaction head to rotate up and down and swing-hammer the track back and forth, which can further promote the track to be more tightly compacted after laying. 3. In the present invention, by setting the buffer mechanism, when the first hammer compaction head generates excessive up-and-down hammering pressure, the first hammer compaction head can also make the movable block move upward for buffering through the connecting rod and compress the buffer spring. In this way, through the compression buffering of the buffer spring, the first hammer compaction head can further have a good buffering effect to prevent the track from being damaged due to excessive pressure during the assisted hammer compaction. This auxiliary equipment for rail transit engineering construction can conveniently and quickly assist in hammering and compacting the track during the construction of rail transit engineering. It avoids the situation in the existing track laying that often relies on manual hammering and compacting, which is difficult to ensure the tight fit between the track and the roadbed. It also avoids the drawbacks that the installation accuracy of the track is difficult to control due to the limited and uneven manual hammering force. Moreover, only by the operation of one motor can the two functional effects of the first hammer compaction head assisting in up-and-down hammering and the second hammer compaction head rotating and swinging up and down back and forth be achieved, improving the work efficiency. Thus, it can efficiently assist in hammering and compacting the track, ensuring that the track is more densely compacted after laying and making the overall use effect better.

[0023] Such as Figure 1-5A kind of auxiliary equipment for rail transit engineering construction shown in the figure. During the construction of rail transit engineering, by setting a hammering and compaction structure, the track can be assisted in hammering and compaction. That is, when in use: the motor 4 works to drive the turntable 5 and the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the linkage column 8, the buffer seat 9, the connecting rod 10 and the first hammering and compaction head 11 to move up and down through the rotating connecting rod 7, so that the first hammering and compaction head 11 moves up and down to assist in hammering the laid track 12 up and down, so as to make the track 12 more tightly compacted after laying; at the same time, when the motor 4 works, it also drives the first sprocket 15 to rotate through the output shaft.

In this way, through the compression and buffering of the buffer spring 903, the first hammering and compaction head 11 can further have a good buffering effect to prevent the track 12 from being damaged due to excessive pressure during the auxiliary hammering and compaction; it avoids the situation in the existing track laying that often relies on manual use of simple tools (such as hammers, crowbars, etc.) for hammering and compaction, and it is difficult to ensure the tight and stable fit between the track and the roadbed.
