[0027] As shown in Figure 1 and Figure 2 , the track base top surface detection and adjustment device 10 includes an inclination detection part 11, a positioning part 12, and a base adjustment part 13. The positioning part 12 is used to determine the current position of the device on the base top surface. The inclination detection part 11 is used to detect and display the inclination angle of the base top surface where the device is located, so as to provide a reference basis for the adjustment of the base top surface at that place. The base adjustment part 13 is used to adjust the inclination angle of the base top surface where the device is located when needed. In this embodiment, the device 10 is used to detect and adjust the inclination angle of the base top surface (i.e., the vibration isolator mounting surface) at the predetermined vibration isolator mounting position in the track.

[0028] The inclination detection part 11 comprises an angle sensor assembly (not shown in the figure), a digital display assembly 112, and a plurality of function buttons 113. The angle sensor assembly is fixed in the device and comprises an angle sensor for detecting the current inclination angle of the device in real time. The digital display assembly 112 comprises a display screen for displaying the real-time detected inclination angle. The function buttons 113 are used for function setting and switching, etc.

[0029] The positioning part 12 comprises a laser line marker assembly 121, which comprises a laser line marker. In the present embodiment, base marker guard piles are installed on both sides of the base at the predetermined isolator installation position, and the laser line marker can mark the base marker guard piles to position the device and ensure that the device is located at the isolator installation position.

[0030] The device further comprises a controller, a power-on button, and a built-in battery. The controller can be in the form of a circuit board, for example. The angle sensor assembly, the laser line marker assembly, the digital display assembly 112, the plurality of function buttons 113, and the power-on button are all connected to the controller. After the power-on button is pressed, the controller controls the angle sensor assembly, the laser line marker assembly, and the digital display assembly 112 to start working and begin receiving the input of the function buttons 113, and then controls the digital display assembly 112 to display the corresponding angle data according to the detection result of the angle sensor.

[0031] The base adjustment part 13 comprises a containing housing 131, a pair of hand-held handles 132, a plurality of connecting columns 133, and an adjustment base 134.

[0032] The containing housing 131 is used to contain and fix the inclination detection part 11 and the positioning part 12. In the present embodiment, the containing housing 131 is in the shape of a rectangular parallelepiped, is hollow inside, and has a plurality of mounting holes on the upper surface and the lower surface, respectively. The angle sensor assembly is fixedly installed inside the containing housing 131, and the digital display assembly 112 is fixedly installed in the containing housing 131, with the display screen of the digital display assembly 112 embedded in the corresponding mounting hole on the upper surface of the containing housing 131. The plurality of function buttons 113 are respectively embedded in the corresponding mounting holes on the upper surface of the containing housing 131. The laser line marker assembly 121 is fixed on the lower surface of the containing housing 131, wherein the direction of the laser projected by the laser line marker is consistent with the width direction of the containing housing 131.

[0033] The pair of hand-held handles 132 are respectively fixedly installed on both sides of the containing housing 131 for the user to hold. In the present embodiment, each hand-held handle 132 is in the shape of a right-angle C and is fixed at both ends to one side surface of the containing housing 131.

[0034] Multiple connecting posts 133 are used to connect the housing 131 to the adjustment base 134. The length of the connecting posts 133 is used to set the distance between the housing 131 and the adjustment base 134, which is approximately the height of the housing 131 relative to the top surface of the base during use. This allows the display screen and function buttons 113 of the digital display component 112 to be positioned at a height that is more convenient for the user to observe and operate. At the same time, the connection via the connecting posts 133 also avoids obstructing the laser marker at the bottom of the housing 131.

[0035] The adjustment base 134 is used to contact the top surface of the base at the installation location of the vibration isolator to provide support for tilt angle detection and to adjust the top surface of the base. In this embodiment, the adjustment base 134 includes an adjustment plate 1341, which is circular and plate-shaped, with a diameter corresponding to the diameter of the vibration isolator. Its bottom surface is approximately flat and is used to simulate the bottom force-bearing surface of the vibration isolator. In this embodiment, the adjustment plate 1341 is designed according to the bottom profile of the vibration isolator, and its diameter is equal to or slightly larger than (difference < 5%) the diameter of the bottom force-bearing surface of the vibration isolator. When the bottom surface of the adjustment plate 1341 is approximately in contact with the top surface of the base, the tilt angle detected by the angle sensor is also the tilt angle at that position on the top surface of the base.

[0036] In this embodiment, the connecting posts 133 are square posts, and there are four in total. One end of each connecting post 133 is connected and fixed to a corner of the bottom surface of the housing 131, and the other end is connected and fixed to the upper surface of the adjusting base 1341. The center line of the adjusting base 1341 is basically coincident with the center line of the housing 131 (the center line at the intersection of the diagonals).

[0042] Step 4, place the handheld track base top surface detection and adjustment device 10 on the isolator mounting surface 210 and ensure that the bottom surface of the adjustment base 1341 is basically completely attached to the isolator mounting surface 210.

[0043] Step 5, press the start button to start the track base top surface detection and adjustment device 10, adjust the position of the track base top surface detection and adjustment device 10 on the base top surface 200 according to the deviation of the laser line projected by the laser line instrument from the isolator base marker stake 220, and ensure that the laser line coincides with the isolator base marker stake 220.

[0044] Step 6, determine whether the inclination angle of the isolator mounting surface 210 meets the predetermined inclination angle requirement through the angle data displayed on the display screen of the digital display assembly 112 at the top of the track base top surface detection and adjustment device 10.

[0045] Step 7, when it is determined in step 6 that the requirement is not met, confirm the adjustment range and angle according to the difference between the measured inclination angle and the predetermined inclination angle.

[0046] Step 8, press the handheld handle 132 to generate pressure on the isolator mounting surface 210 with the adjustment base 1341, thereby adjusting it. During the adjustment process, ensure that the center of the track base top surface detection and adjustment device 10 is stable and does not move along the longitudinal direction of the line, correctly press the handheld handle 132 on both sides according to the real-time angle data displayed, and always observe the angle data displayed on the digital display screen. When the displayed angle data is basically consistent with the predetermined inclination angle, stop pressing.

[0053] In addition, the device also has the advantages of relatively small overall size, convenient carrying and operation.

[0054] <Embodiment Two>

[0055] The embodiment provides a track base top surface detection and adjustment device, and the same reference signs are given to the same constituent elements in the embodiment one and the corresponding description is omitted.

[0056] Figure 5 is a perspective view of the track base top surface detection and adjustment device in the embodiment, Figure 6 is a schematic view of the track base top surface detection and adjustment device in the embodiment.

[0057] As Figure 5 and Figure 6 The difference between the embodiment and the first embodiment is that the structure of the base adjusting part 13' in the track base top surface detecting and adjusting device 10' is different.

[0058] The base adjusting part 13' in the embodiment comprises a rotating base plate 1342, a rotating bearing 1343 and a plurality of limiting components 1344 in addition to the adjusting base plate 1341.

[0059] The rotating base plate 1342 is also a circular plate and its diameter is smaller than that of the adjusting base plate 1341. One end of each connecting column 133 is fixedly connected to a corner of the bottom surface of the accommodating housing 131 and the other end is fixedly connected to the upper surface of the rotating base plate 1342. The rotating base plate 1342 is coaxially arranged with the adjusting base plate 1341 and is rotatably arranged on the adjusting base plate 1341 through a rotating shaft (not shown in the figure) and the rotating bearing 1343.

[0060] The edge portion of the rotating base plate 1342 has a plurality of limiting member mounting holes 1342a and the limiting components 1344 are mounted in the limiting member mounting holes 1342a. In the embodiment, the rotating base plate 1342 has four limiting member mounting holes 1342a which are uniformly distributed along the circumference of the edge portion and each limiting member mounting hole 1342a is located between two adjacent connecting columns 133. Four limiting components 1344 are correspondingly mounted. The limiting components 1344 are limiting beads (also known as limiting top beads) which comprise a mounting housing, a spring and a steel bead. The mounting housing can be, for example, a cylindrical housing with one end closed and is fitted into the limiting member mounting hole 1342a (circular hole). The spring is arranged in the mounting housing and the steel bead is arranged at the open end of the mounting housing. The two ends of the spring respectively abut against the inner bottom surface of the mounting housing and the steel bead.

[0061] The upper surface of the adjusting base plate 1341 has a plurality of limiting matching portions (not shown in the figure) which correspond to the number and distribution of the limiting member mounting holes 1342a. The limiting matching portions can be, for example, circular bottom grooves. When the rotating base plate 1342 is rotated to a position where the plurality of limiting member mounting holes 1342a are respectively aligned with the plurality of limiting matching portions in the vertical direction, the steel beads of the limiting components 1344 are respectively pressed into the circular bottom grooves, thereby limiting the rotation of the rotating base plate 1342. When the rotating base plate 1342 is rotated with a larger force, the steel beads will be rolled out of the circular bottom grooves and the rotating base plate 1342 will be rotated. Therefore, through the limiting components 1344, the construction personnel can conveniently rotate the rotating base plate 1342 by 90 degrees each time and the angle sensor assembly and the laser line instrument assembly fixed on the rotating base plate 1342 will also be rotated by 90 degrees.

One of the plurality of function keys 113 can be used as a limiting piece unlocking key. When the function key 113 is pressed, the plurality of limiting components 1344 are unlocked.

[0063] In this embodiment, other structures are the same as those in Embodiment One, and thus will not be repeated.

[0064] Using the track base top surface detection and adjustment device 10' of this embodiment, after the transverse inclination angle detection and adjustment of the vibration isolator mounting surface according to Steps 1-8 in Embodiment One, the longitudinal inclination angle detection and adjustment can be further implemented according to the following steps:

[0065] Step 9: The construction personnel rotate the rotating base 1342 and the containing shell 131 by 90 degrees, for example, the construction personnel can hold the hand-held handle 132, press the adjustment base 134, and then rotate it with force until the limiting components 1344 (limiting beads) are embedded in the limiting matching portions on the adjustment base 1341 again. Alternatively, the plurality of limiting components 1344 can be unlocked by the function key 113, and then the rotating base 1342 is rotated.

[0066] Step 10: After rotation, the longitudinal inclination angle detection and adjustment of the vibration isolator mounting surface are repeated according to Steps 6-8.

[0067] Similarly, the above steps can be repeated to detect and adjust all vibration isolator mounting surfaces.

[0068] Effects of Embodiment Two

[0069] According to the track base top surface detection and adjustment device provided in this embodiment, on the basis of the effects of Embodiment One, since the base adjustment portion further has a rotating base, a rotating shaft, and a rotating bearing, the inclination detection portion can be rotated relative to the adjustment base, so that the device can be used to detect the inclination angles of the vibration isolator mounting surface in multiple directions, and the use is more convenient when needed.

[0070] In this embodiment, four limiting beads are uniformly distributed on the rotating base, and the adjustment base has a plurality of circular bottom grooves corresponding thereto. Through such a configuration, the construction personnel can conveniently and accurately rotate the rotating base, the containing shell, and the angle sensor fixed thereon by 90 degrees each time, so as to detect the transverse and longitudinal inclination angles of the vibration isolator mounting surface.

[0071] The above embodiments are only used for illustrating the specific implementation manners of the present application, and the present application is not limited to the description range of the above embodiments. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and the description in the specification are only used for illustrating the principle of the present application.
