[0002] The roadbed is the foundation of the road surface, which is excavated or filled and compacted on the original ground. According to the cross-sectional form of the roadbed, it is divided into filled roadbed, excavated roadbed and semi-filled and semi-excavated roadbed. According to the different uses of the road, the thickness and materials of the roadbed are also very different when filling the roadbed. A roadbed with a suitable thickness can greatly extend the service life of the road. At present, the thickness of the roadbed filling is generally constructed by workers based on experience. The thickness of the filling cannot be controlled very accurately, and it needs to be measured and adjusted again, which is relatively cumbersome.

For example, the patent authorization announcement number is CN218263364U, which is a thickness control device for roadbed filling. The device uses two main frames as supports, and a control panel is connected between the two column main frames. During the filling process, the filling thickness is controlled by observing the control panel. Although the device can control the filling thickness, it is directly placed in the filling site, which will hinder the filling construction to a certain extent, and the range of observable control is limited, and frequent movement is required to achieve control of different areas.

[0028] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, this embodiment proposes a thickness control tool for roadbed filling, which includes:

[0030] A base 1, a vertical pole 2 is fixedly connected to the base 1, and a scale mark 3 is provided on the vertical pole 2;

[0031] The sliding sleeve 4 is slidably mounted on the vertical pole 2, and a positioning mechanism 5 for fixing the sliding sleeve 4 to a current height is provided on the sliding sleeve 4;

[0032] The infrared ray device 6 is arranged on one side of the sliding sleeve 4 , and a rotating mechanism 7 for adjusting the rotation angle of the infrared ray device 6 is commonly connected between the sliding sleeve 4 and the infrared ray device.

[0033] When in use, the base 1 is placed on the base, the infrared ray device 6 is turned on, the sleeve 4 is manually slid to adjust the pre-filling height, and when it is moved to the appropriate position, the sleeve 4 is positioned to the current position through the positioning mechanism 5, and then the infrared ray device 6 is rotated to adjust the slope of the roadbed to be filled; during the filling process, the staff observes the infrared rays to ensure the accuracy of the filling thickness. The equipment avoids hindering the staff's construction during the observation of the filling process, and at the same time facilitates the staff to grasp the accuracy of the filling thickness.

[0034] In some embodiments, a reading hole 8 for reading the scale mark 3 is provided on the sleeve 4. When adjusting the height, the adjuster observes the sliding height of the sleeve 4 through the reading hole 8 to ensure that the sleeve 4 is accurately fixed at a certain height of the vertical pole 2 to ensure the accuracy of the roadbed filling thickness.

[0035] In some embodiments, a level ruler 9 is detachably connected to the base 1, and the staff observes the levelness of the base 1 through the level ruler 9 to avoid the skewness of the upright pole 2 to ensure the accuracy of the roadbed filling thickness. In some embodiments, an iron sheet or a magnetic sheet is bonded to the upper surface of the base 1, and a magnetic block is provided at the bottom of the level ruler 9. The two are fixed by magnetic attraction, which is easy to take, and the level ruler 9 can be repeatedly used in different occasions.

[0036] In some embodiments, the positioning mechanism 5 includes a threaded hole 51 opened on one side of the sliding sleeve 4, and also includes a threaded rod 52 adapted to the threaded hole 51 and capable of penetrating the sliding sleeve 4. The end of the threaded rod 52 located inside the sliding sleeve 4 is connected to a top plate 53, and the end of the threaded rod 52 located outside the sliding sleeve 4 is connected to a rotating handle 54. When the sliding sleeve 4 is adjusted to a suitable height, the threaded rod 52 is driven to rotate by screwing the rotating handle 54. When the threaded rod 52 rotates, it is threadedly connected with the threaded hole 51. In the process of the cooperation between the two, the top plate 53 is driven to feed inward until the top plate 53 presses against the side wall of the vertical pole 2. The rotating handle 54 is continuously screwed until it rotates to the limit. After the top plate 53 presses against the side wall of the vertical pole 2, the fixing of the sliding sleeve 4 is achieved.

[0037] In some embodiments, the rotating mechanism 7 includes two ear plates 71 fixed to one side of the sliding sleeve 4, a rotatable rotating shaft 72 is connected between the two ear plates 71, the rotating shaft 72 passes through one ear plate 71 and is connected to a rotating handle 73, a ratchet 74 is sleeved on the rotating shaft 72, and a pawl 75 is provided on one side of the ratchet 74; two connecting plates 76 are respectively connected to the two sides of the rotating shaft 72, and the other ends of the two connecting plates 76 are commonly connected to the infrared ray device 6. When the angle of the infrared device 6 needs to be adjusted, the rotating handle 73 is turned, and the rotating handle 73 drives the rotating shaft 72, the ratchet 74, the connecting plate 76 and the infrared device 6 to rotate clockwise with the rotating shaft 72 as the center point. When it is rotated to a suitable angle, the gravity of the infrared device 6 itself will drive the ratchet 74 to rotate counterclockwise. Under the restriction of the pawl 75, the ratchet 74 can be stopped from rotating counterclockwise, so that the infrared device 6 is fixed at the current angle; when the infrared device 6 needs to rotate counterclockwise, the pawl 75 is manually adjusted to make the ratchet 74 free from the restriction of the pawl 75, and the counterclockwise rotation adjustment of the infrared device 6 can be achieved by turning the rotating handle 73. When it is adjusted to a suitable position, the pawl 75 is reset to make it clamp the ratchet 74 to further fix the infrared device 6 at the current angle.

[0038] Furthermore, a rotating rod 77 is connected between the two ear plates 71, and the ratchet 75 includes a rotating portion 75a and a limiting portion 75b. The rotating portion 75a is rotatably sleeved on the rotating rod 77, and the limiting portion 75b is used to lock the ratchet 74. A pressing plate 75c for unlocking the ratchet 74 is fixedly connected to the rotating portion 75a. The limiting portion 75b is lifted up by pressing the pressing plate 75c to release the locking of the ratchet 74, and the pressing plate 75c is convenient for the staff to operate. Springs are respectively connected to both sides of the limiting portion 75b, and the other end of the spring extends downwardly and is connected to the inner wall of the ear plate 71. The limiting portion 75b is pulled down by the spring, so that the limiting portion 75b always locks the ratchet 74 without manual intervention.

[0039] refer to Figure 3 The pressing plate 75c is located on the left side of the limiting portion 75b, and a pull rope 78 is connected to the left end of the pressing plate 75c, and the pull rope 78 extends to the bottom of the ear plate 71. This design facilitates the staff to adjust the infrared ray device 6 counterclockwise. When adjusting the infrared ray device 6 counterclockwise, the thumb and index finger pinch the connecting rope and pull it down to release the pawl 75 from the restriction on the ratchet 74, and the middle finger and ring finger hold the angle of the adjusting connecting plate 76. After adjusting to a suitable position, the connecting rope pawl 75 is released to lock the ratchet 74 again under the action of the spring, so that the angle adjustment of the infrared ray device 6 can be achieved with one hand. This design simplifies the adjustment steps and is easy to operate.

[0040] Furthermore, an arc groove 76a is provided on the connecting plate 76. When the connecting plate 76 rotates upward, the rotating rod 77 is located in the arc groove 76a. In some embodiments, the ratchet 74 is arranged in the middle part of the clock, and the two connecting plates 76 are respectively connected to the two sides of the ratchet 74. When the connecting plate 76 rotates, the connecting plate 76 may interfere with the rotating rod 77, so that the connecting plate 76 cannot rotate after rotating upward at a certain angle. Therefore, an arc groove 76a is provided on the connecting plate 76. During the rotation process, the rotating rod 77 is located in the arc groove 76a to avoid interference between the two, so that the connecting plate 76 and the infrared ray device 6 can rotate upward at a greater angle.

[0041] In some embodiments, the ends of the two connecting plates 76 are connected to a block 10, a groove 11 in a "T" shape is provided in the block 10, and a slider 12 is fixedly connected to the infrared ray device 6, and the slider 12 is inserted into the groove 11. In this embodiment, the infrared ray device 6 can be disassembled at any time, so that the infrared ray device 6 can be disassembled for other construction projects when not in use; during transportation, the infrared ray device 6 and the base 1 can be transported separately to avoid damage to the fragile infrared ray device 6 during transportation.

[0042] Working principle of this device:

[0043] S1: Place the base 1 on the base, and observe the level ruler 9 to ensure that the upright 2 is vertical to the base;

[0044] S2: Turn on the infrared ray device 6, slide the sleeve 4 upward, determine the specific height of the current sleeve 4 through the reading hole 8, and when the sleeve 4 slides to the specified height, fix the sleeve 4 by screwing the rotating handle 54;

[0045] S3: When it is necessary to adjust the angle of the infrared ray device 6 upward, turn the rotating handle 73 clockwise to a suitable angle and then stop rotating. Under the interference of the pawl 75, the infrared ray device 6 is fixed at the current angle; when it is necessary to adjust the infrared ray device 6 downward, pull down the pull rope 78, the pawl 75 releases the lock on the ratchet 74, support the connecting plate 76 and adjust it to a suitable position, then release the pull rope 78, and under the action of the spring, the pawl 75 locks the ratchet 74 to fix the infrared ray device 6 to the current angle.

[0046] S4: The staff performs thickness filling construction and observes the infrared rays emitted by the infrared ray device 6 during the construction process to ensure the accuracy of the filling thickness.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
