Description

Technical Field

[0001] This utility model belongs to the field of railway side ditch technology, specifically relating to a railway side ditch telescopic ruler positioning device. Background Technology

[0002] Side ditches are drainage facilities used in road engineering to remove surface water and shallow groundwater near the roadbed. Their core function is to maintain the stability of the roadbed structure. According to relevant design specifications dated December 26, 2024, the depth of side ditches is typically set at 0.6 meters. This parameter ensures drainage efficiency while balancing construction difficulty and project cost. Too shallow a depth may lead to water accumulation problems, while too deep a depth will significantly increase the workload.

[0003] Existing railway side ditch telescopic ruler positioning devices still have some defects. Most railway side ditch telescopic ruler positioning devices use chalk lines to control the planar position of the template during use, which has the disadvantage of being difficult to check and is prone to causing planar position deviation. It is difficult to guarantee the alignment of the side wall template. Therefore, we propose a railway side ditch telescopic ruler positioning device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a railway side ditch telescopic ruler locator, comprising a first measuring ruler, a second measuring ruler on one side of the first measuring ruler, a third measuring ruler inside the second measuring ruler, the third measuring ruler and the first measuring ruler being fixedly connected, sliding blocks on both sides of the third measuring ruler, a sliding rod inside the second measuring ruler, the sliding rod and the sliding block being slidably connected, a connecting block on one side of the first measuring ruler and the second measuring ruler, an installation block on one side of the connecting block, and a lifting adjustment block at the bottom of the installation block.

[0006] Preferably, the mounting block has mounting holes inside, and the top of the lifting adjustment block has mounting buckles.

[0007] Preferably, a bubble level is provided on the top of the connecting block, and the bubble level is fixedly connected to the connecting block.

[0008] Preferably, an infrared laser is provided at the bottom of the connecting block, and the infrared laser is fixedly connected to the connecting block.

[0009] Preferably, the lifting adjustment block has an adjustable threaded rod inside, and the adjustable threaded rod and the lifting adjustment block are threadedly connected.

[0010] Preferably, the adjustable threaded rod has a base at its bottom and a side groove at its top.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. A third measuring ruler is installed inside the second measuring ruler. The third measuring ruler is fixedly connected to the first measuring ruler. The third measuring ruler slides and adjusts inside the second measuring ruler, enabling it to perform length extension measurements on larger side ditches. This improves the convenience of adjusting, measuring, and observing the railway side ditch telescopic ruler positioner.

[0013] 2. A connecting block is provided on one side of both the first and second measuring rulers, and an installation block is provided on one side of the connecting block. The installation block is fixed to the top of the lifting adjustment block. The first and second measuring rulers are adjusted to be close to the top of the side ditch by adjusting the lifting adjustment block on the surface of the adjustable threaded rod, so as to realize the measurement function of the side ditch and improve the convenience of using the railway side ditch telescopic ruler positioner.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a railway side ditch telescopic ruler locator, including a first measuring ruler 1, a second measuring ruler 2 on one side of the first measuring ruler 1, a third measuring ruler 3 inside the second measuring ruler 2, the third measuring ruler 3 and the first measuring ruler 1 being fixedly connected, sliding blocks 4 on both sides of the third measuring ruler 3, a sliding rod 5 inside the second measuring ruler 2, the sliding rod 5 and the sliding block 4 being slidably connected, a connecting block 6 on one side of the first measuring ruler 1 and the second measuring ruler 2, an mounting block 7 on one side of the connecting block 6, and a lifting adjustment block 8 at the bottom of the mounting block 7. The third measuring ruler 3 connects the first measuring ruler 1 and the second measuring ruler 2, so that when measuring the side ditch 15, if the distance to the side ditch 15 is large, the measuring ruler is adjusted by pulling the second measuring ruler 2, causing the sliding block 4 to slide on the surface of the sliding rod 5. When the second measuring ruler 2 moves, the third measuring ruler 3 is exposed, and the length is recorded by observing the distance between the first measuring ruler 1, the second measuring ruler 2 and the third measuring ruler 3.

[0022] Specifically, the mounting block 7 has mounting holes 9 inside, and the top of the lifting adjustment block 8 has mounting buckles 10. The mounting block 7 is fixed to the top of the lifting adjustment block 8 through the mounting holes 9 and the mounting buckles 10.

[0023] Specifically, a bubble level 11 is provided on the top of the connecting block 6. The bubble level 11 and the connecting block 6 are fixedly connected. The measuring ruler is judged to be in a horizontal state by observing the bubble through the bubble level 11.

[0024] Specifically, an infrared laser 12 is provided at the bottom of the connecting block 6. The infrared laser 12 and the connecting block 6 are fixedly connected. The infrared laser 12 is used to measure the horizontal accuracy of the inner wall of the side groove 15.

[0025] Specifically, the lifting adjustment block 8 is provided with an adjustable threaded rod 13 inside, and the adjustable threaded rod 13 and the lifting adjustment block 8 are threadedly connected, so that the height of the lifting adjustment block 8 can be adjusted by the adjustable threaded rod 13.

[0026] Specifically, the adjustable threaded rod 13 has a base 14 at its bottom and a side groove 15 at its top. Measurements are taken using a measuring ruler through the base 14 and the side groove 15.

[0027] In this embodiment, during use, when the measured distance of the side ditch 15 is large, the measuring ruler is adjusted, the second measuring ruler 2 is pulled, and its sliding block 4 slides on the surface of the sliding rod 5. When the second measuring ruler 2 moves, the third measuring ruler 3 is exposed. The length is recorded by observing the distance between the first measuring ruler 1, the second measuring ruler 2 and the third measuring ruler 3. The bubble level 11 is observed to determine whether the first measuring ruler 1, the second measuring ruler 2 and the third measuring ruler 3 are in a horizontal state.
