Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] In the description of the present application, the terms "first", "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0034] The existing measurement needs to stop for rest during long-time handheld movement. The wheel width of the existing rolling linear detection equipment is consistent, and the equipment is easy to sink when detecting some loose road surfaces. However, the wide wheel has poor adaptability to some curved detection routes and is easy to have large errors. Therefore, in order to solve the above problems, the technical scheme is proposed as follows:

[0035] Please refer to Figures 1 to 7The application provides a linear data detection equipment technical scheme for ground engineering, which comprises a detection wheel 1, a rod 2 installed on the top of the detection wheel 1, adjusting handles 3 connected between the rods 2, handles 4 arranged at the ends of the rods 2, a display 5 installed on the side of the handle 4, the detection wheel 1 comprising a main detection wheel 11 and an auxiliary detection wheel 12, the main detection wheel 11 comprising a shell 111 and a detection main plate 112, a rotating main wheel body 116 installed in the shell 111, the main wheel body 116 connected with a linkage wheel 115 arranged in the shell 111, the detection main plate 112 connected with a sensor 114 in the shell 111, the main wheel body 116 rotating to drive the linkage wheel 115 to rotate the sensor 114, a movable pointer 117 further installed on the main shaft of the main wheel body 116, the shell 111 connected with the auxiliary detection wheel 12 through a movable groove 118 on the side of the shell 111, an adjuster 113 further arranged on the top of the shell 111, the auxiliary detection wheel 12 in the movable groove 118 driven to rotate by the adjuster 113, the auxiliary detection wheel 12 comprising a first limiting frame 121 connected with the main detection wheel 11 and a second limiting frame 122 installed in an inner wheel 123 of the auxiliary detection wheel 12, a movable rim 124 rotatably connected to the outer portion of the inner wheel 123, and an outer ring 125 wrapped on the surface of the movable rim 124.

[0036] The main structure of the device comprises the detection wheel 1, the rod 2, the adjusting handle 3, the handle 4, and the display 5.

[0037] The structure of the detection wheel 1 comprises the main detection wheel 11 and the auxiliary detection wheel 12, the main detection wheel 11 is used for data measurement, and the auxiliary detection wheel 12 is used for auxiliary closing.

[0038] The pointer 117 is further installed on the main shaft of the main wheel body 116, and the pointer 117 is perpendicular to the ground under the action of gravity, so that the reading can be observed more conveniently.

[0039] The traditional linear measuring device wheel width cannot be adjusted, and the measuring accuracy is weak when adapting to different road surfaces. In contrast, the application is improved by increasing the auxiliary detection wheel 12 and the main detection wheel 11. The auxiliary detection wheel 12 is connected to the movable groove 118 through the first limiting frame 121. The middle part of the shell 111 is also provided with an adjuster 113. The main detection wheel 11 installed in the movable groove 118 can be rotated by the adjuster 113.

[0040] The first limiting frame 121 is installed in the inner wheel 123 and locked by a bolt. The movable rim 124 is arranged on the outer circle of the inner wheel 123 and rotates. The outer circle 125 is nested on the surface of the movable rim 124. The wheel diameter of the outer circle 125 is consistent with the wheel diameter of the main wheel body 116. After coincidence, the overall wheel width is larger, and it is more stable when passing through the gravel road.

[0041] The first limiting frame 121 arranged in the inner wheel 123 can not only be turned through the gear linkage of the adjuster 113, but also can lock the outer circle 125. Its main role is to limit the rotation of the outer circle 125 so that it can be used as a support when not in use, which is convenient for parking recording.

[0042] The movable rod 211 of the first limiting frame 121 is nested with the gear linkage of the adjuster 113. When the movable rod 211 rotates, the top 216 inside the sliding frame 213 will move. The sliding frame 213 drives the clamping horizontal plate 215 to clamp and limit the movable rim 124 and the outer circle 125, so as to avoid their rotation. Then the second limiting frame 122 can be rotated to adhere to the ground.

[0043] The frame body 222 of the second limiting frame 122 is provided with a rotating support 223. The support 223 is connected with the movable rod 211 through the detent wheel 226. The movable rod 211 adopts an electromagnetic push rod structure. In daily situation, the rod body of the controller 221 presses the detent wheel 226, so that the displacement stroke of the detent wheel 226 installed on one side of the support 223 is limited. When it is necessary to place the support, the controller 221 is connected with voltage. The push rod in the middle of the controller 221 is attracted. At this time, the support 223 is tilted and adheres to the ground under the action of its own weight. Then the controller 221 is quickly de-energized to form self-locking of the detent wheel 226.

[0044] The movable shaft 224 is arranged on the top of the handle 223 and is connected with the movable ring 225, the movable ring 225 is mainly used for nested cooperation with the shaft in the main wheel body 116, and can be locked when being closed, so as to reduce shaking, since the suction of the second limiting frame 122 is in a fixed state, the main wheel body 116 is arranged with a fixed plate body which is connected with the shaft body, and the rotating part of the main wheel body 116 is connected through a bearing, so that the main wheel body 116 can limit the second limiting frame 122 without affecting the work of the main wheel body 116.

[0045] The movable ring 225 arranged on the movable shaft 224 is movable, can be freely attached to the ground, and can record the position through the spraying paint method, so as to improve the convenience of use.

[0046] The use of the present application is as follows:

[0047] The battery and the display are arranged in the display 5, the wire of the display 5 is connected with the detection main plate 112 of the main detection wheel 11 through the rod 2, and the battery in the display 5 is charged through the embedded display.

[0048] When the handheld handle 4 is opened through the key, the detection wheel 1 is pushed to move through the rod 2, in the moving process, the main wheel body 116 drives the linkage wheel 115 to rotate, the linkage wheel 115 is linked with the sensor 114, so that the sensor 114 generates an electric signal, and the sensor 114 is displayed on the display 5 through the signal processing of the detection main plate 112.

[0049] When it is needed to move quickly, the large wheel width will affect the coefficient of the slightly convex stones on the road surface, so it is needed to press the button on the display 5, control the rotation of the adjuster 113, and the rotation of the adjuster 113 drives the auxiliary detection wheel 12 to flip.

[0050] When flipping, the angle of flipping is slightly lifted from the ground, so that the quick work can be carried out, and the outer ring 125 can be laterally assisted to improve the stability of the movement.

[0051] When it is needed to stop and rest, the controller 221 is separated, so that the handle 223 falls on the ground, and the auxiliary of the movable ring 225 can quickly mark, so as to facilitate the recording.

[0052] The improved device makes the wheel width adjustable (main detection wheel 11+auxiliary detection wheel 12), and through the closing / developing cooperation of the auxiliary detection wheel 12 and the main detection wheel 11, the dynamic adjustment of the wheel width is realized: when closing (the outer ring 125 coincides with the main wheel body 116), the wheel width is increased, and the measurement stability of the complex terrain such as the gravel road is improved; when developing, the wheel width is reduced, the interference of the protruding stones with the rapid movement is avoided, the efficiency and the accuracy are taken into account, the handle 223 of the second limiting frame 122 is controlled through the electromagnetic push rod (movable rod 211), after being electrified, the handle 223 is tilted and falls to the ground by the dead weight, and after being de-energized, the handle 223 is self-locked, one-key support is realized, the movable ring 225 is nested with the central shaft of the main wheel body 116, can be freely attached to the ground and mark the position through spraying paint, and the recording efficiency is improved.

[0053] The above only describes the basic principles and the preferred embodiments of the present application, and those skilled in the art can make many changes and improvements according to the above description, and these changes and improvements should belong to the protection scope of the present application.

[0054] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
