Description

Technical Field

[0001] The utility model belongs to the technical field of ditch section auxiliary measurement, and in particular relates to a ditch section auxiliary measurement device. Background Art

[0002] After the ditch is built, the cross-sectional dimensions of the ditch need to be measured and accepted. The general measurement operation is that one person stands on each side of the ditch and two to three people stand at the bottom of the ditch. Each person holds an RTK measuring instrument to perform point measurement. However, due to the inconsistent walking speeds of multiple people, multiple marking points may not be on the same standard cross-section, resulting in cross-sectional measurement deviations and affecting the subsequent acceptance results. Therefore, it is very practical to develop a measurement auxiliary device that can keep multiple RTK measuring instruments working synchronously to solve the measurement deviation caused by inconsistent walking speeds.

The other components and connection methods are the same as those of the third embodiment.

[0044] Specific implementation method five: Combination Figures 1 to 16 To explain this embodiment, this embodiment differs from the specific embodiment four in that the mounting bracket assembly 12 includes a back plate 121 and a bracket 122. The back plate 121 is arranged on the back side of the mounting frame 11 and is detachably connected to the mounting frame 11 by bolts. The bracket 122 is arranged on the front side of the mounting frame 11, and one end of the bracket 122 passes through the mounting frame 11 and is fixedly connected to the back plate 121. A rectangular blind hole 123 extending downward is processed on the top of the bracket 122, and the rectangular blind hole 123 is located on the front side of the mounting frame 11. A through hole is processed at the bottom center of the rectangular blind hole 123. The measuring device 5 is embedded in the rectangular blind hole 123 on the bracket 122, and the measuring end of the measuring device 5 passes through the through hole at the bottom of the rectangular blind hole 123 and extends to the bottom of the bracket 122. Two connecting stepped holes 125 are processed on the top of the bracket 122 away from the mounting frame 11, and each connecting stepped hole 125 is corresponding to the top of a mounting bracket arm 13. Other components and connection methods are the same as those in the fourth embodiment.

[0045] Specific implementation method six: combination Figures 1 to 16This embodiment is described. The difference between this embodiment and the fifth embodiment is that the mounting plate assembly further includes two mounting pressure plates 17. The mounting pressure plates 17 are both arranged on the top of the support plate 122, and the mounting pressure plates 17 are inverted L-shaped pressure plates. Two insertion holes 124 are machined on the top of the support plate 122. The two insertion holes 124 are relatively arranged on both sides of the rectangular blind hole 123. The bottom end of the vertical portion of each mounting pressure plate 17 is correspondingly inserted into one insertion hole 124. The horizontal portion of each mounting pressure plate 17 is arranged above the measuring device 5, and a layer of rubber pad is attached to the bottom of the horizontal portion of each mounting pressure plate 17. The horizontal portion of each mounting pressure plate 17 contacts the top of the measuring device 5 through the rubber pad. Other components and connection methods are the same as those of the fifth embodiment.

[0046] In combination with the specific embodiments three to six, the mounting frame 11 as the main supporting component of the device is made of a plurality of aluminum alloy profiles welded and fixed, and the overall structure is an L-shaped frame structure. The vertical portion of the mounting frame 11 and the horizontal portion of the mounting frame 11 are connected and reinforced by inclined steel bars. Two horizontally arranged aluminum alloy profiles are arranged in the middle of the vertical portion of the mounting frame 11 for fixing the mounting pallet assembly 12. The mounting pallet assembly 12 is used to carry the measuring device, wherein the back plate 121 is used to be fixed to the mounting frame 11, and the pallet 122 is used to support The rectangular blind hole 123 in the middle of the support plate 122 can limit the bottom of the measuring device 5, so that the bottom of the measuring device 5 can be embedded in the rectangular blind hole 123, so that it will not have obvious shaking effects during movement, ensuring the stability of its installation. At the same time, in order to further improve the installation stability of the measuring device 5, two mounting pressure plates 17 are also provided on the support plate 122. The measuring device 5 is longitudinally limited by the mounting pressure plate 17. The mounting pressure plate 17 and the insertion hole 124 adopt an interference fit assembly method. The horizontal position of the measuring device 5 in the mounting pressure plate 17 is 0. A rubber layer is attached to the bottom to avoid rigid contact between the mounting plate 17 and the measuring device 5, thereby protecting the measuring device 5. The two mounting brackets 13 are used to support the support plate 122 and improve the supporting strength of the support plate 122. A connecting threaded hole is processed on the top of the mounting bracket 13. The connecting threaded hole and the connecting stepped hole 125 are coaxially arranged.

The two pushers 16 are the supporting parts of the staff, and the auxiliary measuring device can be driven to move as a whole by pushing the two pushers.

[0047] Specific implementation method seven: combination Figures 1 to 16This embodiment is described. This embodiment differs from the sixth embodiment in that the spacing adjustment unit 2 includes a stretching net 24, two No. 1 connecting troughs 21, two slideways 22, and four sliders 23. The closed sides of the two No. 1 connecting troughs 21 are arranged parallel to each other. A slideway 22 is fixedly connected to the closed side of each No. 1 connecting trough 21, and the length extension direction of each slideway 22 is the same as the length extension direction of the No. 1 connecting trough 21. The stretching net 24 is arranged between the two slideways 22, and each end of the stretching net 24 is slidably connected to the corresponding slideway 22 via two sliders 23. Each No. 1 connecting trough 21 is detachably connected to the corresponding side connecting plate 14 in the adjacent trench bottom moving unit 1. Other components and connection methods are the same as those in the sixth embodiment.

[0048] Specific implementation method eight: combination Figures 1 to 16 This embodiment is described. This embodiment differs from the seventh embodiment in that the spacing adjustment unit 2 further includes two reinforcement components, which are relatively arranged on the front and rear sides of the spacing adjustment unit, and each reinforcement component is detachably connected to the two No. 1 connecting grooves 21 in the spacing adjustment unit.

[0049] Each No. 1 connecting slot 21 has two connecting posts 25 fixedly connected to its front and rear sides, respectively. The two connecting posts 25 on the same side of the No. 1 connecting slot 21 are symmetrically arranged up and down along the center line of the length direction of the No. 1 connecting slot 21. Each reinforcement assembly is detachably connected to the two No. 1 connecting slots 21 via the four connecting posts 25 on the same side.

[0050] The reinforcement assembly includes two reinforcement rods 26, which are arranged in parallel up and down. Each reinforcement rod 26 includes a fixed rod section 261 and a sliding rod section 262. The sliding rod section 262 is embedded in the back side of the fixed rod section 261. The front side of one end of the sliding rod section 262 is processed with a No. 1 set hole. The front side of the other end of the sliding rod section 262 is provided with a sliding column 263, and one end of the sliding column 263 is fixedly connected to the sliding rod section 262. The outer circumferential surface of the other end of the sliding column 263 is processed with an external thread. The front side of the fixed rod section 261 is processed with a guide groove 264 along the length extension direction of the fixed rod section 261. The fixed rod section 261 is away from the sliding rod section. A No. 2 fitting hole is machined on the front side of one end of 262. The other end of the sliding post 263 passes through the guide slot 264 and extends to the front side of the fixed rod segment 261. A locking nut is fitted on the other end of the sliding post 263. The sliding rod segment 262 is locked and fixed to the fixed rod segment 261 through the sliding post 263 and the locking nut. The sliding rod segment 262 is fitted onto a connecting post 25 on a No. 1 connecting slot 21 through the No. 1 fitting hole. The fixed rod segment 261 is fitted onto a connecting post 25 on the same side and horizontally corresponding to the connecting post 25 fitted with the No. 1 fitting hole on the other No. 1 connecting slot 21 through the No. 2 fitting hole. The other components and connection methods are the same as those of the seventh embodiment.

[0051] In conjunction with the seventh and eighth embodiments, the stretching net 24 is composed of multiple X structures and has a certain strength. The spacing between the two No. 1 connecting troughs 21 can be adjusted by the stretched state of the X structure, thereby achieving the length adjustment of the spacing adjustment unit 2. The design of the spacing adjustment unit 2 can adjust the overall length of the ditch bottom moving structure. For narrower ditches, a combination of two ditch bottom moving units 1 and one spacing adjustment unit 2 can be adopted. For wider ditches, a combination of three ditch bottom moving units 1 and two spacing adjustment units 2 can be adopted. This allows auxiliary measurement of ditch structures of different widths.

[0052] Taking into account that when the stretching net 24 is stretched too long, its own strength may be affected, reinforcing rods 26 are added on both sides of the spacing adjustment unit 2. The reinforcing rod 26 is a split structure. The strength of the reinforcing rod 26 is adjusted by adjusting the relative position between the fixed rod section 261 and the sliding rod section 262. After adjusting to the target length, the two are locked and fixed by locking bolts to ensure that the relative position of the two does not change. After the length of the reinforcing rod 26 is determined, the sleeve holes at both ends of the reinforcing rod 26 are matched with the connecting column 25 to install the reinforcing rod 26 on the spacing adjustment unit 2, thereby reinforcing the strength of the spacing adjustment unit 2 to prevent it from deforming during movement. A plurality of connecting holes are processed on the inner walls of both sides of the connecting groove in the No. 1 connecting groove body 21 along the length extension direction of the No. 1 connecting groove body 21, and the connecting holes on the No. 1 connecting groove body 21 are correspondingly matched with the connecting holes on the side connecting plate 14. The No. 1 connecting groove body 21 and the side connecting plate 14 are detachably connected by a plurality of bolt and nut assemblies.

[0053] Specific implementation method nine: combination Figures 1 to 16 This embodiment differs from the eighth embodiment in that the slope adjustment unit 3 includes two No. 2 connecting troughs 31 and two telescopic rods 32. The closed sides of the two No. 2 connecting troughs 31 are arranged parallel to each other. The two telescopic rods 32 are arranged between the two No. 2 connecting troughs 31. The two ends of each telescopic rod 32 are removably connected to the closed side of the corresponding No. 2 connecting trough 31 via a bolt and nut assembly. One No. 2 connecting trough 31 is removably connected to the corresponding side connecting plate 14 of the adjacent trench bottom movable unit 1, and the other No. 2 connecting trough 31 is removably connected to the corresponding trench top movable unit 4. The other components and connection methods are the same as those of the eighth embodiment.

[0054] In this embodiment, the slope adjustment unit 3 is mainly used to adapt to the slope angles on both sides of the ditch, which is specifically achieved by changing the shape of the quadrilateral frame composed of the two No. 2 connecting grooves 31 and the two telescopic rods 32. The two No. 2 connecting grooves 31 in the slope adjustment unit 3 are kept parallel from beginning to end because they are used to connect the ditch bottom moving unit 1 and the ditch top moving unit 4. The length and installation angle of the telescopic rod 32 can be changed to adapt to the ditch slope angle. When in use, first adjust the length of the telescopic rod 32 according to the length of the ditch slope, and then adjust the length of the telescopic rod 32 according to the length of the ditch slope. The arrangement angle of the telescopic rod 32 is adjusted according to the angle of the ditch slope. When the angle of the telescopic rod 32 is determined, the two ends of the telescopic rod 32 are fixed to the two No. 2 connecting grooves 31 by bolts to ensure the structural stability of the slope adjustment unit 3. A plurality of connecting holes are processed on the inner walls on both sides of the connecting groove in the No. 2 connecting groove 31 along the length extension direction of the No. 2 connecting groove 31, and the connecting holes on the No. 2 connecting groove 31 are arranged to correspond to the connecting holes on the side connecting plate 14. The No. 2 connecting groove 31 and the side connecting plate 14 are detachably connected by a plurality of bolt and nut assemblies.

[0055] Specific implementation method ten: Combination Figures 1 to 16 This embodiment is described. The difference between this embodiment and the ninth embodiment is that the composition structure of the trench top moving unit 4 is the same as that of the trench bottom moving unit 1. Other components and connection methods are the same as those of the ninth embodiment.

A ditch with a small width generally uses two ditch bottom moving units 1 and one spacing adjustment unit 2 to form a ditch bottom moving structure:

[0059] First, two trench bottom moving units 1 and a spacing adjustment unit 2 are combined into a trench bottom moving structure, and the two trench bottom moving units 1 are ensured to be located at both ends of the trench bottom to be measured. The structural dimensions of the slope adjustment unit 3 are adjusted according to the inclination angle of the slope of the trench side slope and the length of the slope. After the structural dimensions of the slope adjustment unit 3 are determined, the second connecting trough 31 and the telescopic rod 32 are fixed by the locking bolts to form a firm quadrilateral frame.
