[0046] The present application provides a road pit detection equipment for municipal road maintenance.

[0047] Please refer to Figures 1 to 4 In an embodiment of the present application, the road pit detection equipment for municipal road maintenance comprises:

[0048] A marker 1, both ends of the marker 1 are provided with a support 101;

[0049] A sliding frame 2, the sliding frame 2 is slidingly installed on the marker 1;

[0050] A distance measuring mechanism 3, the distance measuring mechanism 3 comprises a mounting frame 31, a distance measuring device 32 and a positioning bolt 33, the distance measuring device 32 is installed on the mounting frame 31, the positioning bolt 33 comprises a knob part 331 and a shaft part 332, the knob part 331 is arranged at one end of the shaft part 332, the other end of the shaft part 332 penetrates through the mounting frame 31 and is threadedly connected with the sliding frame 2;

[0051] A marker plate 4, the marker plate 4 is installed at the end of the marker 1;

[0052] A line marking mechanism 5, the line marking mechanism 5 is installed on the sliding frame 2, and the line marking mechanism 5 is used for marking a to-be-measured area;

[0053] The marker 1 comprises a rotating arm 11, a bearing arm 12 and a positioning arm 13, the rotating arm 11 is rotationally connected with the bearing arm 12, the bearing arm 12 is detachably connected with the positioning arm 13 through a connecting structure 6, two supports 101 are respectively installed at the bottom of the rotating arm 11 and the positioning arm 13, and the marker plate 4 is installed on the positioning arm 13.

[0054] When measuring the pit, according to the shape of the pit, the square or triangle or combination of square and triangle is determined to measure the line; after the shape is determined, the marker 1 is placed at the boundary of the pit, the initial state, the detection end of the distance measuring device 32 is horizontally directed to the marker plate 4, the sliding frame 2 is moved, the line marking mechanism 5 is located at the initial end of the pit boundary, then the sliding frame 2 is moved along the marker 1 to start marking by the line marking mechanism 5, at this time the distance measuring device 32 acts with the marker plate 4, the distance of marking is measured, when one side measurement is completed, the other side of the pit is marked and measured in the same way, when the boundary of the pit is measured, at this time the knob part 331 can be twisted, through the thread action of the shaft part 332, the knob part 331 is separated from the mounting frame 31, the mounting frame 31 is rotated, the detection end of the distance measuring device 32 is downward, then the knob part 331 is tightened, the mounting frame 31 is pressed on the sliding frame 2 by the knob part 331, the distance measuring device 32 is limited, then the depth value of the pit is measured, when the bottom of the pit is not flat, the depth of the pit at multiple positions can be measured;

[0055] Thus, the measurement of the pit is completed at the same time of marking, it does not need to be divided into multiple steps, and the length, width and depth of the pit can be quickly measured by the marker 1 cooperating with the distance measuring mechanism 3, the measurement efficiency is improved, especially when the pit needs to be divided into multiple shapes for measurement.

[0056] Wherein, when the detection end of the distance measuring device 32 is initially in contact with the marker plate 4, that is, the distance measured each time is the length value of the line, when the detection end of the distance measuring device 32 has a spacing from the marker plate 4, the measurement value of the distance measuring device 32 is reduced by the initial spacing value when the marking is completed;

[0057] When measuring the depth, in an embodiment, the detection of the distance measuring device 32 is flush with the bottom of the support 101, that is, the detection end of the distance measuring device 32 is flush with the test road surface, at this time the detected depth is the depth value of the pit detection point; in another embodiment, the detection end of the distance measuring device 32 has a preset distance from the bottom of the support 101, to avoid that the detection end of the distance measuring device 32 is attached to the ground when the device is placed on the ground, at this time the detected depth value needs to be reduced by the preset distance value.

[0058] In the embodiment, the distance measuring device 32 is a laser distance measuring device, which can also be an ultrasonic distance measuring device, a radar distance measuring device, etc.

[0059] Please refer to Figure 2A nut is embedded on one side of the sliding frame 2, and a threaded end of the shaft portion 332 away from the knob portion 331 is provided with a screw thread, and the shaft portion 332 is threadedly connected with the nut; or a threaded hole is formed on the sliding frame 2 to achieve threaded connection, and the portion of the shaft portion 332 corresponding to the sleeve of the mounting frame 31 is smooth and is not provided with a screw thread. The distance measuring device 32 is preferably detachably assembled with the mounting frame 31.

[0060] The knob portion 331 is provided with a non-slip pad to increase the friction between the mounting frame 31, so that the mounting frame 31 can be more stably squeezed on the sliding frame 2. The side of the mounting frame 31 corresponding to the sliding frame 2 is preferably provided with a non-slip pad to improve the stability during squeezing. The non-slip pad is made of rubber or leather.

[0061] The length of the staff 1 is not less than 50 cm, and is preferably 100 cm.

[0062] In this embodiment, the bottom of the sliding frame 2 is provided with a roller.

[0063] By setting the staff 1 as the rotating arm 11, the bearing arm 12 and the positioning arm 13, when measuring a larger crack on the road, due to the limited length of the staff 1, the length of the crack cannot be measured by moving the sliding frame 2 along the staff 1.

[0064] When measuring the length of a longer crack, the sliding frame 2 is moved to the bearing arm 12, the positioning arm 13 is detached from the bearing arm 12, and then the rotating arm 11 is turned upward. The rotating arm 11 can be used as a pull handle, such as Figure 8 The sliding frame 2 and the bearing arm 12 can be connected through the connecting structure 6, the positioning arm 13 is placed at the starting end of the crack to be measured by the support 101, i.e. the staff 4 is located at the starting end of the crack, and then the bearing arm 12 is pulled by the rotating arm 11 to move the distance measuring device 32 and the marking mechanism 5 through the sliding frame 2. The marking mechanism 5 marks along the boundary of the crack, and the distance measuring device 32 measures the distance with the staff 4. Thus, the measuring device can be adapted to measure potholes and also measure larger cracks.

[0065] For larger potholes, when the length of the pothole is much larger than the length of the staff 1, the bearing arm 12 and the positioning arm 13 can be separated, and the above method can be used to measure the length of the pothole.

[0066] For cracks, when the crack has branches in different directions, the position of the staff 4 can be adjusted, and other branch cracks can be measured in the same way.

[0067] Please refer to Figure 3In this embodiment, the marking mechanism 5 includes a storage cylinder 51 and a blocking rod 52. The storage cylinder 51 is installed on the sliding frame 2. One end of the blocking rod 52 blocks the discharge pipe 511 of the storage cylinder 51, and the other end of the blocking rod 52 passes through the top of the storage cylinder 51 and is threadedly connected to the top of the storage cylinder 51.

[0068] The storage cylinder 51 is filled with lime powder for marking, but other colored powders can also be used. When marking is required, the blocking rod 52 is turned counterclockwise, and the blocking rod 52 moves upward due to the action of the thread, driving the bottom of the blocking rod 52 to move out of the discharge pipe 511. At this time, the powder flows out through the discharge pipe 511, and the moving slide frame 2 drives the marking mechanism 5 to move to achieve the marking function.

[0069] When marking is not required, the blocking rod 52 is screwed clockwise, and the blocking rod 52 moves downward through the action of the thread, so that its bottom end blocks the discharge pipe 511.

[0070] The storage cylinder 51 includes a cylinder body and a cylinder cover. The cylinder cover is threadedly connected to the top of the cylinder body. By unscrewing the cylinder cover, lime powder can be easily filled into the storage cylinder 51.

[0071] The top end of the blocking rod 52 passes through the cylinder cover and is threadedly connected to the cylinder cover, and a nut is installed on the cylinder cover; a handle is provided at the top end of the blocking rod 52 to facilitate the rotation of the blocking rod 52.

[0072] In other embodiments, the marking mechanism 5 includes a connecting arm, a bolt and a fixed frame. The fixed frame is installed on the sliding frame 2. The connecting arm is vertically slidably installed on the fixed frame. An assembly groove is provided at the bottom end of the connecting arm. The bolt is threadedly connected to the side of the connecting arm. Chalk can be placed in the assembly groove, and the bolt is tightened to tighten the chalk; chalk is used for marking.

[0073] See also Figure 1 As an optional method of this embodiment, a strip-shaped hole 102 is opened on the marking rod 1, and the discharge pipe 511 passes through the strip-shaped hole 102.

[0074] By providing the strip-shaped hole 102, the discharge pipe 511 can be set as a straight pipe, passing through the strip-shaped hole 102, to facilitate the subsequent powder spreading work;

[0075] As another optional method of this embodiment, the middle part of the discharge pipe 511 can also be set to be inclined so that its bottom end is located on one side of the pole 1.

[0076] Please refer to Figure 4 and Figure 7As an optional manner of this embodiment, the carrying arm 12 is provided with a first mounting portion 122, and the positioning arm 13 is provided with a second mounting portion 131. The connecting structure 6 includes a connecting plate 61, a connecting shaft 62 and a U-shaped sleeve 63. One end of the connecting shaft 62 is rotatably connected to the connecting plate 61, and the other end of the connecting shaft 62 sequentially passes through the first mounting portion 122 and the second mounting portion 131 and is threadedly connected to the second mounting portion 131. The U-shaped sleeve 63 is installed on the end of the connecting shaft 62 away from the connecting plate 61.

[0077] The positioning bolt 33 further includes a driving block 333 . The driving block 333 is mounted at the end of the shaft portion 332 and located inside the sliding frame 2 . The driving block 333 is aligned with the U-shaped sleeve 63 .

[0078] Among them, when the positioning bolt 33 is tightened to limit the mounting frame 31, the driving block 333 at the end of the shaft 332 is in a horizontal setting, and when the connecting shaft 62 and the second mounting portion 131 are threadedly tightened, that is, the connecting plate 61 is in contact with the first mounting portion 122, then the U-shaped sleeve 63 is horizontal, and the openings on both sides are aligned with the driving block 333.

[0079] When testing a crack, the width and depth of the crack can be measured first, and then the carrying arm 12 and the positioning arm 13 can be unlocked to measure the length;

[0080] After the crack depth test is completed, the sliding frame 2 is slid onto the carrying arm 12 so that the driving block 333 is inserted into the U-shaped sleeve 63. Figure 9 In (a), the knob portion 331 is turned counterclockwise to separate the knob portion 331 from the mounting bracket 31, the mounting bracket 31 is loosened, and the distance measuring device 32 is adjusted to rotate horizontally by rotating the mounting bracket 31. In preparation for the subsequent length measurement, the driving block 333 can simultaneously drive the U-shaped sleeve 63 to rotate, and the U-shaped sleeve 63 drives the connecting shaft 62 to rotate, so that the connecting shaft 62 is gradually separated from the threaded connector 132 on the second mounting portion 131, as shown in FIG. Figure 9 (b) in the figure, the connecting plate 61 can then be pulled to separate the U-shaped sleeve 63 from the driving block 333 and the threaded connector 132 in sequence, as shown in FIG. Figure 9 Then, turn the distance measuring device 32 to the horizontal position, turn the knob 331 clockwise, and squeeze the mounting bracket 31 to limit the distance measuring device 32. Then, pull the positioning arm 13 and the carrying arm 12 apart, as shown in FIG. Figure 9 (d) in.

[0081] When the carrying arm 12 and the positioning arm 13 are subsequently connected again, the connecting plate 61 is pushed so that the U-shaped sleeve 63 is again sleeved on the driving block 333, and the rotating knob part 331 drives the U-shaped sleeve 63 to rotate through the driving block 333, so that the connecting shaft 62 is assembled with the threaded connector 132.

[0082] As shown in Figure 7 , the threaded connecting piece 132 is a nut embedded in the second mounting portion 131, or a threaded hole is formed in the second mounting portion 131 to achieve threaded connection with the connecting shaft 62.

[0083] Correspondingly, a through hole is formed on the first mounting portion 122, and the connecting shaft 62 passes through the through hole and is threaded with the threaded connecting piece 132.

[0084] Among them, the strip-shaped hole 102 is formed on the rotating arm 11 and the bearing arm 12.

[0085] The support 101 is preferably frame-shaped, so that when the rotating arm 11 is used as a pull rod, the staff can hold the support 101, facilitating pulling the entire device.

[0086] As another optional way of the embodiment, the connecting structure 6 adopts a bolt, which is threaded through the first mounting portion 122 and the second mounting portion 131, and a wrench or a knob is provided at the end of the bolt for dismounting the bolt.

[0087] As shown in Figure 5 and Figure 6 , as a preferred way of the embodiment, the connecting structure 6 further comprises a positioning shaft 64, which is installed at one end of the connecting plate 61 away from the connecting shaft 62, and sequentially penetrates the bearing arm 12 and the rotating arm 11.

[0088] By setting the positioning shaft 64 to sequentially penetrate the bearing arm 12 and the rotating arm 11, the positioning shaft 64 can limit the rotating arm 11 when detecting potholes and the like, so that the bearing arm 12 and the rotating arm 11 remain horizontal, and the rotating arm 11 will not rotate, thereby facilitating the movement of the sliding frame 2 along the entire marker 1.

[0089] And the positioning shaft 64 is connected to the connecting plate 61, when the connecting shaft 62 is separated from the threaded connecting piece 132, the connecting shaft 62 pushes the connecting plate 61 to drive the positioning shaft 64 to separate from the rotating arm 11, so as to automatically realize unlocking;

[0090] Among them, a U-shaped groove is formed at the end of the bearing arm 12, a rotating shaft is installed in the U-shaped groove, the rotating arm 11 is sleeved on the rotating shaft, a positioning hole 111 is formed on one side wall of the U-shaped groove and the rotating arm 11, and the positioning shaft 64 sequentially penetrates the two positioning holes 111 to realize axial limiting of the bearing arm 12 and the rotating arm 11; the positioning shaft 64 does not enter the strip-shaped hole 102, and will not affect the movement of the storage cylinder 51 along the marker 1 with the sliding frame 2.

[0091] Preferably, a baffle is arranged at the bottom of the U-shaped groove to support the rotating arm 11 and allow the rotating arm 11 to rotate upward only.

[0092] Please refer to Figure 5 and Figure 6 As a preferred mode of the embodiment, the connecting structure 6 further comprises a limiting shaft 65, which is installed on the side of the connecting plate 61 away from the connecting shaft 62, and a limiting hole 21 is formed on the sliding frame 2. When the driving block 333 is inserted into the U-shaped sleeve 63, the limiting hole 21 is aligned with the limiting shaft 65.

[0093] By arranging the limiting shaft 65, rotating the knob part 331, and making the driving block 333 rotate the connecting shaft 62 through the U-shaped sleeve 63, the connecting shaft 62 is separated from the threaded connecting piece 132, the connecting plate 61 is pushed towards the limiting hole 21, the positioning shaft 64 is driven out of the positioning hole 111, and the limiting shaft 65 is inserted into the limiting hole 21. When the connecting plate 61 is moved to make the U-shaped sleeve 63 move out of the threaded connecting piece 132, the limiting shaft 65 is completely inserted into the limiting hole 21, as shown in (d) of Figure 9 , so that the sliding frame 2 can be limited relative to the bearing arm 12, and the sliding frame 2 is prevented from sliding out of the bearing arm 12.

[0094] As another optional mode of the embodiment, a bolt can also be arranged, and a limiting hole 21 and a threaded hole are formed on the sliding frame 2 and the bearing arm 12 correspondingly. The bolt is screwed through the limiting hole 21 and the threaded hole to achieve the limiting of the sliding frame 2.

[0095] Please refer to Figure 1 As an optional mode of the embodiment, a mark line 121 is arranged on the bearing arm 12, and the driving block 333 is inserted into the U-shaped sleeve 63 when the side edge of the sliding frame 2 is aligned with the mark line 121.

[0096] By arranging the mark line 121, the driving block 333 is correspondingly inserted into the U-shaped sleeve 63 when the side edge of the sliding frame 2 is aligned with the mark line 121, so that the driving block 333 and the U-shaped sleeve 63 can be quickly assembled.

[0097] Please refer to Figure 5 and Figure 6 As a preferred mode of the embodiment, the connecting shaft 62 is screwed with the first mounting part 122, and the connecting shaft 62 is screwed with the first mounting part 122 at the same time when the connecting shaft 62 is rotated and the second mounting part 131 is unscrewed.

[0098] Correspondingly, a nut is prearranged in the first mounting part 122 to achieve the threaded connection with the connecting shaft 62.

[0099] By setting the same thread on both ends of the connecting shaft 62, the connecting stability can be improved by being screwed with the bearing arm 12 and the positioning arm 13 at the same time, and when the connecting shaft 62 is separated from the threaded connecting piece 132, the limiting shaft 65 has been partially inserted into the limiting hole 21, so that when the limiting shaft 65 is horizontally displaced relative to the limiting hole 21 in the subsequent movement measurement process, the limiting shaft 65 can be ensured to be partially located in the limiting hole 21 by the thread surface on the connecting shaft 62 and the nut limiting on the first mounting portion 122.

[0100] Please refer to Figure 2 and Figure 8 As an optional mode of the embodiment, the road pit detection equipment for municipal road maintenance further comprises a positioning piece 7, the positioning piece 7 comprises a connecting frame 71 and a blocking shaft 72, the blocking shaft 72 is installed on the sliding frame 2 through the connecting frame 71, when the detection end of the distance measuring equipment 32 horizontally faces the marker plate 4, the blocking shaft 72 abuts against the side edge of the mounting frame 31, and when the detection end of the distance measuring equipment 32 vertically faces downward, the blocking shaft 72 abuts against the top of the mounting frame 31.

[0101] By setting the blocking shaft 72, please refer to (b) in Figure 8 When the distance measuring equipment 32 is horizontal, the side edge of the mounting frame 31 contacts the blocking shaft 72 at this time, when the distance measuring equipment 32 is vertical, the top of the mounting frame 31 contacts the blocking shaft 72 at this time, and whether the distance measuring equipment 32 is horizontal or vertical can be quickly determined by using the blocking shaft 72.

[0102] The working principle of the road pit detection equipment for municipal road maintenance provided by the application is as follows:

[0103] When the pit is measured, the square or triangle or combination of square and triangle is determined according to the shape of the pit to draw a line for measurement, after the shape is determined, the marker 1 is placed at the boundary of the pit, the initial state, the detection end of the distance measuring equipment 32 horizontally faces the marker plate 4, the sliding frame 2 is moved, the line drawing mechanism 5 is located at the initial end of the pit boundary, then the sliding frame 2 is moved along the marker 1 to start drawing a line by using the line drawing mechanism 5, at this time, the distance measuring equipment 32 acts on the marker plate 4, the distance of the line drawing is measured, when one side of the measurement is completed, the other side of the pit is measured by drawing a line in the same way, when the boundary of the pit is measured, the knob portion 331 is twisted at this time, the knob portion 331 is separated from the mounting frame 31 by the thread action of the shaft portion 332, the mounting frame 31 is rotated, the detection end of the distance measuring equipment 32 faces downward, then the knob portion 331 is tightened, the mounting frame 31 is pressed on the sliding frame 2 by the knob portion 331, the distance measuring equipment 32 is limited, then the depth value of the pit is measured, when the bottom of the pit is not flat, the depth of the pit at multiple positions can be measured.

[0104] When measuring the length of a long crack, the sliding frame 2 is moved to the carrying arm 12, the positioning arm 13 is detached from the carrying arm 12, and then the rotating arm 11 is turned upward, and the rotating arm 11 can be used as a pull handle, as shown in Figure 8 Subsequently, the sliding frame 2 and the carrying arm 12 can be connected through the connecting structure 6, the positioning arm 13 is placed at the starting end of the crack to be measured by the support 101, i.e., the marker plate 4 is located at the starting end of the crack, and then the carrying arm 12 is pulled by the rotating arm 11 to move the ranging device 32 and the marking mechanism 5 through the sliding frame 2, the marking mechanism 5 marks along the boundary of the crack, and the ranging device 32 acts with the marker plate 4 to measure the distance, so that the measuring device can be adapted to measure the pit and can also be adapted to measure the long crack.

[0105] When measuring the crack, the width and depth of the crack can be measured first, and then the length can be measured by unlocking the carrying arm 12 and the positioning arm 13.

[0106] When the depth of the crack is measured, the sliding frame 2 is slid onto the carrying arm 12, and the driving block 333 is inserted into the U-shaped sleeve 63, as shown in Figure 9 (a) of FIG. 11, the knob part 331 is detached from the mounting frame 31 by counterclockwise turning, the mounting frame 31 is loosened, and the ranging device 32 is adjusted to be horizontal by turning the mounting frame 31, which is prepared for subsequent length measurement. The driving block 333 can simultaneously drive the U-shaped sleeve 63 to rotate, the U-shaped sleeve 63 drives the connecting shaft 62 to rotate, the connecting shaft 62 gradually separates from the threaded connecting piece 132 on the second mounting part 131, and at the same time, the connecting shaft 62 pushes the connecting plate 61 to drive the positioning shaft 64 to separate from the positioning hole 111 on the rotating arm 11, and the connecting plate 61 drives the limiting shaft 65 to be inserted into the limiting hole 21 to limit the sliding frame 2, as shown in Figure 9 (b) of FIG. 11, and then the connecting plate 61 can be pulled to separate the U-shaped sleeve 63 from the driving block 333 and the threaded connecting piece 132 in sequence, and the limiting shaft 65 is completely inserted into the limiting hole 21, as shown in Figure 9 (c) of FIG. 11, and then the ranging device 32 is turned to be horizontal, and the knob part 331 is turned clockwise to press the mounting frame 31 to limit the ranging device 32. Subsequently, the positioning arm 13 is separated from the carrying arm 12, as shown in Figure 9 (d) of FIG. 11, and the rotating arm 11 is used as a handle, as shown in Figure 8 (b) of FIG. 11.

[0107] Therefore, when measuring a long measurement area such as a crack, the ranging device 32 is adjusted from the state of measuring the length within the range of the marker 1 to the state of measuring the length greater than the length of the marker 1.

[0108] The above merely illustrates the embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process conversion, or direct or indirect application in other related technical fields, which is made according to the content of the present application, shall be included in the patent protection scope of the present application.
