Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road construction measurement, in particular to a measurement auxiliary device suitable for different road surfaces. Background Art
[0002] The road surface is a layered structure paved on the roadbed with various materials for vehicles to travel. Although the unpaved roadbed can also drive vehicles, its ability to resist natural factors and vehicle loads is very poor. It is dusty when it is sunny and muddy when it rains. When driving, the surface will be rugged and uneven, causing the vehicle to bump and slip, the driving speed is low, and even impassable, and the oil and machine parts are seriously consumed. Therefore, the road surface is often paved. When the road surface is constructed, the length and distance of the road surface are usually measured to facilitate the budget of the required materials. The existing road surface measurement method usually uses a hand-pushed distance measuring wheel to measure the unpaved road surface. Since no measurement auxiliary device is set on the outside of the distance measuring wheel, when encountering a muddy section during the measurement after rain, since the muddy road surface is soft, the distance measuring wheel may sink into the soft mud when pushing the distance measuring wheel to measure the road surface, which will affect the accuracy of the measurement data and make the device not well applicable to different road surfaces. Therefore, a measurement auxiliary device suitable for different road surfaces is proposed to address the above problems. Utility Model Content

Based on the specific implementation methods in the utility model, all other specific implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1
[0020] like Figure 1-4 As shown, a measurement auxiliary device suitable for different road surfaces comprises a distance measuring wheel 1, the outer side of the wheel of the distance measuring wheel 1 is provided with evenly distributed protrusions, the outer side of the support rod of the distance measuring wheel 1 is provided with a fixed block 2, the inner front end of the fixed block 2 is rotatably connected with a gear 3 through a rotating shaft, one end of the outer side of the gear 3 is meshedly connected with a first rack 4, the outer side of the first rack 4 is fixedly connected with a bracket 5, and the bracket 5 passes through the fixed block 2, the bracket 5 is slidably connected to the fixed block 2, the bottom end of the bracket 5 is fixedly connected with a support plate 6, the other end of the outer side of the gear 3 is meshedly connected with a second rack 7, the outer side of the second rack 7 is fixedly connected with a handle 8, and the handle 8 passes through the fixed block 2, and the handle 8 is slidably connected to the fixed block 2. Example 2
[0021] like Figure 1-2As shown, in order to solve the problem that the support plate 6 will be inserted into the softer muddy road surface when the pushing device causes the support plate 6 to slide with the road surface, the wheel of the distance measuring wheel 1 passes through the support plate 6, and the left and right ends of the support plate 6 are both arranged in an arc shape. By arranging the two ends of the support plate 6 in an arc shape, when the pushing device causes the support plate 6 to slide with the road surface, the support plate 6 can be prevented from being inserted into the softer muddy road surface. Example 3
[0022] like Figure 2-4 As shown, in order to solve the problem that it is inconvenient to control the reset of the control support plate 6 after it contacts the ground, the inner bottom end of the handle 8 is slidably connected to the limit block 9, and the limit block 9 is fixedly connected to the fixed block 2, and the outer side of the limit block 9 is fixedly connected to a spring 10, and the other end of the spring 10 is fixedly connected to the handle 8. After the control support plate 6 contacts the ground, when the positioning of the handle 8 is released, the elastic force of the spring 10 after being stretched is restored, and the handle 8 can be pulled to reset under the support of the limit block 9, and then the second rack 7 is driven by the handle 8 to engage the gear 3, and further engage the first rack 4, which facilitates the reset of the control support plate 6 through the bracket 5. Example 4
[0023] like Figure 1-2 As shown, in order to solve the problem of inconvenience in positioning the control support plate 6 after it contacts the ground, the front end of the handle of the distance measuring wheel 1 is fixedly connected to a steel clamping rod 11 through a connecting block, and the clamping rod 11 is clamped and connected with the handle 8, and a pull rod 12 is fixedly connected to the outside of the clamping rod 11. After the control support plate 6 contacts the ground, the steel clamping rod 11 is deformed in the process of contacting the handle 8, and then is clamped together with the handle 8 after resetting. At this time, the pulled handle 8 can be positioned, thereby realizing the positioning of the support plate 6 pushed to contact the ground. Example 5
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, in order to solve the problem that it is inconvenient to install the auxiliary support structure on the outside of the distance measuring wheel 1, the rear end of the inner side of the fixed block 2 is rotatably connected with a bidirectional threaded shaft 13 with opposite thread directions on both sides, and the bidirectional threaded shaft 13 penetrates the fixed block 2, and the outer side of the bidirectional threaded shaft 13 is spirally connected with a clamping block 14, and the clamping block 14 is slidably connected to the fixed block 2, and the outer side of the clamping block 14 is fixedly connected with a gasket 15 made of rubber material, and the gasket 15 is in close contact with the support rod of the distance measuring wheel 1. By placing the clamping block 14 at the rear end of the fixed block 2 on the outer side of the support rod of the distance measuring wheel 1, and then rotating the bidirectional threaded shaft 13 with opposite thread directions on both sides to be spirally connected with the clamping block 14, the clamping block 14 further drives the gasket 15 made of rubber material to be in close contact with the support rod of the distance measuring wheel 1, so that the auxiliary support structure is conveniently installed on the outer side of the distance measuring wheel 1.
[0025] In this embodiment, when the device is used to measure the road surface, the clamping block 14 at the rear end of the fixing block 2 is first placed on the outside of the strut of the distance measuring wheel 1, and then the two-way threaded shaft 13 with opposite thread directions on both sides is rotated to be spirally connected with the clamping block 14, so that the clamping block 14 further drives the rubber gasket 15 to be in close contact with the strut of the distance measuring wheel 1. At this time, the auxiliary support structure is installed on the distance measuring wheel 1. After completing the above operations, when a softer muddy section is encountered during the process of measuring the road surface by the device after rain, the handle 8 is pulled to make the second rack 6 engage with the gear 3. At this time, the limit block 9 will continuously slide with the handle 8, and the spring 10 will continuously be stretched, because the gear 3 will also engage with the first rack 4 at the same time. By controlling the bracket 5 to push the support plate 6 downward in the process of the gear 3 meshing with the first rack 4, when the support plate 6 contacts the ground, the steel clamping rod 11 is deformed in the process of contacting the handle 8, and then is clamped together with the handle 8 after being reset. At this time, the handle 8 can be positioned after being pulled, thereby realizing the positioning of the support plate 6 pushed to contact the ground. After positioning, the pushing device can be used to perform measurement operations on a soft muddy road surface. At this time, by making the support plate 6 slide against the road surface in the process of pushing the device, when measuring the road surface through the distance measuring wheel 1 with evenly distributed protrusions on the outside of the wheel, the wheel of the distance measuring wheel 1 can be prevented from sinking into the soft mud, thereby ensuring the accuracy of the road surface measurement data.
