Description

Technical Field

[0001] This utility model relates to the field of urban rail transit, specifically to a special construction equipment that integrates drilling and installation of floating slab track positioning pins and grinding of bottom flatness. Background Technology

[0002] Urban rail transit, as a safe, convenient, efficient, and green modern transportation mode, plays an increasingly important role in meeting public travel needs, alleviating urban traffic pressure, and promoting urban economic development. Steel spring floating slab track, a widely used low-frequency vibration isolation structure in urban rail transit systems, has excellent vibration reduction and noise reduction performance. This structure typically consists of a floating slab, vibration isolators, a limiting system, and a foundation track bed. Among these, the vibration isolators, as the key supporting components between the floating slab and the foundation, directly affect the mechanical properties and service life of the track structure.

[0003] During the construction of the floating slab track, to ensure the accurate installation of the floating slab and the effective operation of the vibration isolation system, it is necessary to drill positioning pin holes at the bottom of the vibration isolators in the foundation concrete, and to perform fine leveling treatment on the foundation surface of the vibration isolator installation area to meet strict flatness and elevation control requirements. If the ground is uneven, some vibration isolators will be subjected to force first, generating eccentric loads, which will lead to problems such as decreased vibration isolation performance, uneven stress on the floating slab, and early structural damage. At the same time, uneven ground will also affect the perpendicularity of the positioning pin holes, making it difficult to install the positioning pins of the floating slab in place.

[0004] Currently, the construction of such positioning pin holes and leveling mainly relies on manual operation, which has many shortcomings: First, the accuracy of manual layout and drilling is limited, making it difficult to meet the strict requirements for the positional accuracy of vibration isolators in large-area laying; Second, drilling and grinding require different equipment, the operation process is cumbersome, and frequent tool changes not only reduce efficiency but also increase the intensity of construction; Third, there is currently a lack of a dedicated construction device that can integrate the drilling of vibration isolator positioning pin holes and the grinding of bottom flatness, which limits the overall efficiency and quality control level of track construction. Utility Model Content

[0005] This utility model provides a special construction equipment that integrates drilling and installation of positioning pins for floating slab tracks and grinding of bottom flatness to solve the above-mentioned problems in the prior art, and achieve the purpose of integrating positioning pin hole drilling and fine leveling of the foundation surface, thereby improving construction efficiency and consistency.

[0006] This utility model is achieved through the following technical solution:

[0007] A specialized construction equipment integrating drilling and installation of positioning pins for floating slab tracks and grinding of bottom flatness includes a cutting tool, a rotating shaft connected to the cutting tool, and a first power device for driving the rotating shaft to rotate; it also includes a positioning component connected to the first power device, the positioning component being used for positioning on the outer sleeve of the vibration isolator.

[0008] This utility model proposes a specialized construction equipment integrating drilling and installation of positioning pins for floating slab tracks and grinding of bottom flatness. The cutting tools and rotating shafts are both sized to allow insertion from top to bottom into the outer sleeve of the vibration isolator. The positioning assembly is directly or indirectly connected to the first power unit and can be positioned on the outer sleeve of the vibration isolator.

[0009] When it is necessary to construct the lower foundation of the floating slab track system, the cutting tool is inserted from top to bottom into the outer sleeve of the vibration isolator until the cutting tool contacts the lower foundation, so that the positioning component is positioned on the outer sleeve of the vibration isolator. The first power device drives the rotating shaft to rotate, which in turn drives the cutting tool to rotate. By changing different cutting tools, drilling or grinding operations on the lower foundation can be performed. After the operation is completed, the tooling of this application is removed and the vibration isolator body is reinstalled.

[0010] As can be seen, this application solves the problems of multiple equipment types, complex operation processes, difficulty in ensuring construction accuracy, and low efficiency in the installation of vibration isolators in the prior art. It not only integrates the functions of drilling positioning pin holes and precise leveling of the foundation surface, avoiding switching between multiple equipment and improving construction efficiency and consistency, but also features strong structural adaptability, high construction accuracy, and simple operation. This application effectively improves the construction quality and efficiency of floating slab tracks, is conducive to improving the support state of vibration isolators, and has significant engineering application value and practical significance for enriching the supporting tooling system of track engineering and promoting the advancement of urban rail transit construction technology.

[0011] Furthermore, the positioning component includes a first positioning plate, through which the rotating shaft movably passes. The first positioning plate is used to be placed on top of the outer sleeve of the vibration isolator. In practical use, the first positioning plate is placed on top of the outer sleeve of the vibration isolator, and the outer sleeve of the vibration isolator provides support.

[0012] Furthermore, the positioning assembly also includes a second positioning plate through which the rotating shaft moves; the second positioning plate is located below the first positioning plate and is used to abut against the bottom of the limiting plate inside the outer sleeve of the vibration isolator.

[0013] In existing technology, the outer sleeve of a vibration isolator typically has a limiting plate inside, which is used to limit the longitudinal displacement of the vibration isolator body. In this solution, the second positioning plate is matched with the limiting plate. When using the tooling of this application, the second positioning plate is inserted below the limiting plate, and then the tooling is rotated so that the second positioning plate cannot disengage from the limiting plate through vertical upward movement.

[0014] Furthermore, the first positioning plate and the second positioning plate are connected by several connecting rods. These connecting rods ensure that the first positioning plate and the second positioning plate maintain an integral structure.

[0015] Furthermore, it also includes a height adjustment mechanism for adjusting the relative height between the second positioning plate and the first positioning plate. This solution adjusts the height distance between the second and first positioning plates using this mechanism, thereby ensuring that the second positioning plate can stably abut against the bottom of the limiting plate. This facilitates better adaptation to different vibration isolator outer sleeves, significantly expanding the versatility of this application. The height adjustment mechanism can be implemented using any existing adjustment method, such as common telescopic adjustment or threaded adjustment.

[0016] Furthermore, a connecting component is installed on the first positioning plate, which is used to connect to the first power device. This solution achieves an effective connection between the first power device and the first positioning plate through the connecting component.

[0017] Furthermore, the connecting assembly includes a lifting support fixedly connected to the first power device and a height adjustment mechanism for driving the lifting support to rise and fall.

[0018] To accommodate different heights of outer sleeves and potential issues such as foundation settlement, this solution also includes a height adjustment mechanism to adjust the relative height between the first power unit and the first positioning plate, significantly improving the versatility of this application.

[0019] Furthermore, the height adjustment mechanism includes a support member mounted on the first positioning plate, a rack disposed on the support member, a gear meshing with the rack, and a second power device for driving the gear to rotate; the output end of the gear and / or the second power device is rotatably connected to the lifting support.

[0020] In this solution, the gear is driven to rotate by the second power device, so that the gear moves up and down along the rack, which can synchronously drive the lifting support to move up and down, thereby adjusting the height of the first power device.

[0021] Both the first and second power devices in this application can be implemented using any existing equipment capable of driving the corresponding components to rotate. Preferably, both the first and second power devices have a self-locking function, meaning that when not in operation, they prevent the corresponding components from rotating freely.

[0022] Furthermore, a scale is provided on the support member to facilitate accurate reading and adjustment of the height of the lifting support.

[0023] Furthermore, a clamp is connected to the output end of the first power unit, and the clamp is used to hold the rotating shaft from the top. This solution facilitates independent replacement of the rotating shaft or the first power unit, reducing maintenance costs.

[0024] Furthermore, the cutting tool is detachably connected to the bottom end of the rotating shaft. This design facilitates rapid tool replacement and quick switching between operating conditions, avoiding the problem of frequent equipment changes during construction and significantly improving construction efficiency and consistency.

[0025] Compared with the prior art, this utility model has at least the following advantages and beneficial effects:

[0026] 1. This utility model is a special construction equipment that integrates drilling and installation of positioning pins for floating slab tracks and grinding for bottom flatness. It can realize two functions: drilling positioning pin holes at the bottom of the vibration isolator and grinding and leveling the foundation ground. It avoids the problem of frequent replacement of multiple equipment during construction and significantly improves construction efficiency and consistency.

[0027] 2. This utility model is a special construction equipment that integrates drilling and installation of floating plate track positioning pins and grinding of bottom flatness. Through the positioning component, this application is always kept perpendicular to the ground in the working state, ensuring that the ground grinding reaches the designed flatness, the hole axis is highly perpendicular, and the floating plate positioning pin is installed smoothly.

[0028] 3. This utility model is a special construction equipment that integrates drilling and installation of floating plate track positioning pins and grinding of bottom flatness. It can adjust the height of the cutting tool, so as to accurately control the drilling or grinding depth according to actual needs and meet the requirements of bottom anchoring or leveling depth of different types of vibration isolators.

[0029] 4. This utility model is a special construction equipment that integrates drilling and installation of positioning pins for floating slab tracks and grinding for bottom flatness. It has good structural compatibility and construction adaptability. Furthermore, the precise control of the hole position and the combined effect of foundation leveling effectively avoid construction quality problems such as inaccurate installation of positioning pins, skewed drilling of positioning pins, and uneven ground, which can lead to uneven stress on the vibration isolators. This ensures the stability of the track structure and the reliability of the vibration isolation system from the source. Attached Figure Description

[0040] In this embodiment, the positioning component includes a first positioning plate 4, through which the rotating shaft 2 moves movably. The first positioning plate 4 is used to be placed on top of the outer sleeve of the vibration isolator.

[0041] In this embodiment, the output end of the first power device 9 is connected to a clamp 10, which is used to clamp the rotating shaft 2 from the top. The cutting tool 1 is detachably connected to the bottom end of the rotating shaft 2.

[0042] In this embodiment, the first power unit 9 is an electric motor.

[0043] When used for drilling positioning pin holes, the tool 1 is a drill bit; when used for foundation leveling and grinding, the tool 1 is a grinding wheel.

[0044] This embodiment integrates the functions of drilling positioning pin holes at the bottom of the vibration isolator and fine leveling of the foundation surface, thereby simplifying the construction process, reducing equipment switching and manual operation, improving installation accuracy and construction efficiency, and ensuring the balanced support state of the floating slab track and the effective operation of the vibration isolation system, thus achieving the goal of improving the overall performance and construction quality of the track structure.

[0045] Example 2:

[0046] This is a specialized construction tool integrating drilling and installation of positioning pins for floating slab tracks and grinding for bottom flatness. Based on Example 1, as follows... Figures 1 to 4 As shown:

[0047] The positioning assembly further includes a second positioning plate 3, through which the rotating shaft 2 movably passes; the second positioning plate 3 is located below the first positioning plate 4, and is used to abut against the bottom of the limiting plate inside the outer sleeve of the vibration isolator. The first positioning plate 4 and the second positioning plate 3 are connected by several connecting rods 14.

[0048] A connecting assembly is installed on the first positioning plate 4, and the connecting assembly is used to connect to the first power device 9. The connecting assembly includes a lifting support 7 fixedly connected to the first power device 9 and a height adjustment mechanism for driving the lifting support 7 to rise and fall.

[0049] The height adjustment mechanism includes a support member 5 mounted on the first positioning plate 4, a rack 12 disposed on the support member 5, a gear 15 meshing with the rack 12, and a second power device 6 for driving the gear 15 to rotate; the output end of the gear 15 and / or the second power device 6 is rotatably connected to the lifting support 7; the rack 12 is arranged vertically.

[0050] In this embodiment, the lifting support 7 is fixedly connected to the housing of the first power device 9; the second power device 6 uses a handle with a self-locking function, which allows for manual control of the lifting support 7. The axle 11 of the gear 15 is coaxial with and fixedly connected to the handle.

[0051] In this embodiment, when the first positioning plate 4 is placed on top of the outer sleeve of the vibration isolator, the height of the second positioning plate 3 is exactly at the bottom of the limiting plate inside the outer sleeve of the vibration isolator.

[0052] Preferably, the support member 5 is provided with a longitudinally extending scale 8.

[0054] In a more preferred embodiment, the outer diameter of the first positioning plate 4 is larger than the size of the limiting plate inside the outer sleeve of the vibration isolator. When the second positioning plate 3 abuts against the bottom surface of the limiting plate, the contact between the first positioning plate 4 and the top of the outer sleeve of the vibration isolator can be increased, thereby improving the support of the outer sleeve for the first positioning plate 4.

By adjusting the height between the first positioning plate and the second positioning plate, the second positioning plate 3 cannot pass upward through the limiting plate.

[0058] Rotate the second power unit 6 to adjust the overall height of the first power unit 9, the rotating shaft 2 and the cutter 1 so that the cutter 1 contacts the lower foundation;

[0059] Start the first power unit 9 to make the tool 1 rotate. During the rotation of the tool 1, adjust the height of the tool 1 as needed.
