Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction, and more specifically to an auxiliary measuring device for road and bridge construction. Background Technology

[0002] With the rapid development of modern industry, it has also been widely applied in the field of road and bridge construction.

[0003] For example, CN221460885U, Road Construction Surveying Device, relates to the field of road construction, specifically a road construction surveying device. It includes a support frame, a hand handle fixedly connected to the outer wall of the support frame, a measuring frame fixedly connected to the top of the support frame, and an extension frame movably connected inside the support frame. When transporting the support frame, the support rod is rotated into the extension frame, and then the extension frame is rotated to allow a protrusion to rotate out of a slot at the bottom of the support frame, thus freeing the extension frame from being confined. The extension frame is then moved into the support frame, causing the protrusion to move to one side of a slot at the top of the support frame. Rotating the extension frame again allows the protrusion to rotate into a slot at the top, stabilizing the extension frame and reducing the overall size of the device. The hand handle facilitates transporting the support frame, making storage and transporting the device easier for surveyors. While road surveying devices like this are widely used in the field, their triangular structure is no longer sufficient for diverse applications and they only support a single type of measuring tool.

[0004] For example, CN114321628A discloses a road construction measuring device. This invention relates to the field of road construction measurement technology and proposes a road construction measuring device, including a base, with mounting seats and support frames respectively provided on the upper and lower sides of the base, a platform that can be rotated at any angle and mounted on the mounting seats, a platform for mounting measuring instruments, and a mounting surface on the platform, a telescopic fixing device, one end of which is hinged to the base and the other end to the platform, and several telescopic fixing devices are provided, and a leveling block is provided below the platform, with the line connecting the center of gravity of the leveling block and the center of gravity of the platform perpendicular to the mounting surface. This technical solution solves the problems of inconvenient leveling, slow leveling speed, and low accuracy of existing measuring devices. The support structure of the road measuring device described in this invention is already widely used in the field, but its triangular structure is no longer suitable for multi-scenario use, and it can only effectively support a single measuring tool.

The base plate sinking bracket 102 and the universal wheel 121 are both fixedly connected to the base plate 101. The optical axis connecting assemblies A103, B104, C105, and D106 are also fixedly connected to the base plate 101. The base plate sinking bracket 102 and the top plate 107 are fixedly connected. The base plate sinking bracket 102 is fixedly connected to the bearing seat A120. The directional shaft block A108, directional shaft block B109, directional shaft block C110, differential mounting plate A111, and differential mounting plate B112 are all fixedly connected to the top plate 107. The differential mounting plate A111 and differential mounting plate B112 are both fixedly connected to the differential 114. The differential 114 is fixedly connected to the differential mounting plate A111 and differential mounting plate B112 by fixing bolts 113. The input end of the differential 114 is fixedly connected to the input shaft 115. The input shaft 115 is fixedly connected to the handwheel 116. The handwheel 116 is rotatably connected to the rotating block 117. The rotating block 117 is rotatably connected to the handle 118. The output end of the differential 114 is fixedly connected to the lead screw 119. The lead screw 119 is rotatably connected to the bearing seat A120. Specific Implementation Example 3:

[0025] The following is combined Figures 1-5 This embodiment further describes Example 1. The auxiliary adjustment mechanism 2 includes a sliding plate 201, a directional shaft block D202, a bolt-connected lead screw nut 203, a support shaft A204, a support shaft B205, a support shaft C206, a shaft fixing plate 207, a mounting plate fixing bracket 208, and a mounting plate 209. The directional shaft block D202, the bolt-connected lead screw nut 203, the support shaft A204, the support shaft B205, and the support shaft C206 are all fixedly connected to the sliding plate 201. The sliding plate 201 is fixedly connected to the shaft fixing plate 207 through the support shafts A204, B205, and C206. The shaft fixing plate 207 is fixedly connected to the mounting plate fixing bracket 208, and the mounting plate fixing bracket 208 is fixedly connected to the mounting plate 209.

[0026] This utility model discloses an auxiliary measuring device for road and bridge construction. Its advantages include: a simple structure and low cost; four casters 121 with foot brakes allow for free movement; a hand-cranked measuring tool positioning structure satisfies basic operational needs in various construction environments; a sunken support 102 is a sunken fixed structure with a reserved space around the base plate 101 for placing measuring equipment or modifying other storage mechanisms; and a mounting plate 209 has several equally spaced and equal-length slots for connecting various fixed surveying instruments. 9. The measuring instrument is fixed to the mounting plate bracket 208 by fasteners. The fixing position can be freely disassembled and adjusted using external fasteners such as knurled screws and eye bolts to ensure the central force placement of long and heavy measuring instruments and prevent the instrument from tilting in other directions due to gravity. After fixing the measuring instrument to the mounting plate 209, when it is necessary to adjust the overall height, turn the handle 118 until the handwheel 116 is vertical. The handle 118 can be rotated along the rotating block 117 until it is parallel to the handwheel 116, providing a partial storage function. The operator holds the handle 118 with one hand and rotates the handwheel 116 through the rotating block 117. When the 16 is rotated, it drives the differential 114 to work through the input shaft 115. The output end of the differential 114 drives the lead screw 119 to rotate along the bearing A120. When the lead screw 119 rotates, it drives the bolt-connected lead screw nut 203 to move linearly along the axis of the lead screw 119. When it moves, it drives the sliding plate 201 to move along the same axis through the bolt. When the sliding plate 201 moves, it slides along the optical axis connecting assembly A103, optical axis connecting assembly B104, optical axis connecting assembly C105, and optical axis connecting assembly D106 respectively through the directional shaft blocks D202 at the four corners. The optical axis connecting assembly consists of the upper and lower fixed bearings and the middle optical axis assembly. The upper and lower fixed shaft seats are fixedly connected to the top plate 107 and the bottom plate sinking bracket 102 respectively, so that the moving mechanism 1 and the auxiliary adjustment mechanism 2 are tightly connected through the structure of the optical axis connecting assembly A103, optical axis connecting assembly B104, optical axis connecting assembly C105, and optical axis connecting assembly D106. When the sliding plate 201 moves up and down, it drives the shaft fixing plate 207 to move along through the support shaft A204, support shaft B205, and support shaft C206. The shaft fixing plate 207 drives the measuring equipment to move up and down through the mounting plate fixing bracket 208 and mounting plate 209 until the equipment is adjusted to the required height.
