Technical Field

[0001] The utility model relates to the technical field of road and bridge design and construction, in particular to a road and bridge design and construction auxiliary device. Background Art

[0002] Roads and bridges are generally composed of several major parts, including roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. During the entire process of existing road and bridge construction, construction will be carried out based on the overall design. Before construction begins, it is necessary to use auxiliary equipment to measure and explore the site in advance for the later design drawings.

[0003] Workers often measure the length of roads by using measuring wheels. During measurement, the measuring wheels are pushed manually and the length of the road is calculated based on the number of revolutions of the measuring wheels. However, the measuring wheels are prone to deflection during pushing, which can easily lead to large measurement errors. The push rods of the measuring wheels are generally long and take up more space during transportation, which reduces the convenience of the auxiliary devices during transportation. When measuring roads through measuring wheels, the auxiliary devices generally only measure the length of the roads and require other tools for width measurement, which can easily lead to large limitations in the use of the auxiliary devices.

[0024] When in use, the auxiliary device is placed on one side of the road to be measured, and then the push rod 102 is pushed, so that the push rod 102 pushes the distance measuring wheel 104 to move. At this time, the distance measuring wheel 104 drives the magnetic strip 106 to rotate.

[0026] When in use, the upper connecting seat 201 and the lower connecting seat 203 are fixed under the engagement of the hook 2021 and the buckle 2022. After the auxiliary device is used, one end of the buckle 2022 can be rotated to make the buckle 2022 move away from the hook 2021, so as to separate the upper connecting seat 201 from the lower connecting seat 203, and then the push rod 102 is rotated to fold the push rod 102 for storage, so as to realize the folding function of the auxiliary device on the push rod 102.

The width measuring member 301 includes a placement frame 3011 and a measuring rod 3012 inside. The placement frame 3011 is fixed on the surface of the wheel frame 1, and the measuring rod 3012 is placed inside the placement frame 3011. The structure of the measuring rod 3012 is a T-shaped structure, and the height of the measuring rod 3012 is greater than the height of the wheel frame 1.

[0028] When in use, the measuring rod 3012 can be taken out for measurement. Since the length of the measuring rod 3012 is greater than the height of the wheel frame 1, one end of the measuring tape 302 can be pulled out, and the distance from the measuring tape 302 to the ground can be measured under the action of the measuring rod 3012. Then, the measuring rod 3012 can be placed at the other end of the road, and the measuring tape 302 can be pulled to move the measuring tape 302 to the distance measured before the measuring rod 3012 to ensure that the measuring tape 302 is in a horizontal state. At the same time, the width of the road can be measured under the action of the measuring tape 302 to realize the measurement function of the road width by the auxiliary device.

[0029] Furthermore, if Figure 3 As shown, a path marking mechanism 4 is provided on one side of the wheel frame 1, and the interior of the path marking mechanism 4 includes a containing box 401 and a path marking component 402.

[0031] Working principle: When in use, first place the auxiliary device to one side of the road to be measured, then push the push rod 102, so that the push rod 102 pushes the distance measuring wheel 104 to move. At this time, the distance measuring wheel 104 drives the magnetic strip 106 to rotate. When the magnetic strip 106 rotates to the side of the magnetic sensor 105, the magnetic sensor 105 performs induction counting and transmits the result to the surface of the display screen 103. The length counted once is the arc length between the magnetic strips 106, so as to realize the auxiliary device's function of measuring the length of roads and bridges.

During measuring, the valve 4021 can be opened to discharge the lime in the storage box 401 through the discharge pipe 4022 and fall onto the road surface. The lime moves synchronously with the movement of the distance measuring wheel 104 to mark the moving path.

[0033] At the same time, the measuring rod 3012 can be taken out during measurement. Since the length of the measuring rod 3012 is greater than the height of the wheel frame 1, one end of the measuring tape 302 can be pulled out, and the distance from the measuring tape 302 to the ground can be measured under the action of the measuring rod 3012. Then, the measuring rod 3012 can be placed at the other end of the road, and the measuring tape 302 can be pulled to move the measuring tape 302 to the distance measured before the measuring rod 3012 to ensure that the measuring tape 302 is in a horizontal state. At the same time, the width of the road can be measured under the action of the measuring tape 302 to realize the measurement function of the auxiliary device for the road width, thereby improving the flexibility of the auxiliary device when used.

[0034] At this time, the upper connecting seat 201 and the lower connecting seat 203 are fixed under the engagement of the hook 2021 and the buckle 2022. After the auxiliary device is used, one end of the buckle 2022 can be rotated to make the buckle 2022 move away from the hook 2021, and the upper connecting seat 201 and the lower connecting seat 203 are separated. Then, the push rod 102 is rotated and folded for storage, so as to realize the folding function of the auxiliary device on the push rod 102, thereby improving the convenience of transporting and carrying the auxiliary device, and finally completing the use of the auxiliary device.
