Description

Technical Field

[0001] The utility model mainly relates to the technical field of land reclamation, in particular to a measuring device for land reclamation. Background Art

[0002] Land reclamation actually refers to the activity in which farmers occupy the land owned by the collective economic organization of the village in order to build houses. However, during the construction process, the land is damaged due to excavation, collapse, occupation, etc., and remediation measures are taken to restore the land to a state where it can be used. In the work of land reclamation, it is necessary to use measuring devices to measure the land.

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0026] Please refer to the attached Figure 1-5As shown, the utility model provides a technical solution: a measuring device for land reclamation, including an operating box 10, a lifting mechanism is provided at the upper end of the operating box 10, a rotating assembly is provided on the lifting mechanism, four limiting sleeves 102 are fixedly connected at the four corners of the bottom of the operating box 10, four supporting rods 11 are slidably installed in the four limiting sleeves 102, and a plurality of annular grooves 111 are provided on the outer surfaces of the upper ends of the four supporting rods 11, and a limiting mechanism is provided in the operating box 10, and the cooperation between the limiting mechanism and the annular grooves 111 can keep the device level on an uneven road surface.

[0027] In this embodiment, the limiting mechanism includes a turntable 14 rotatably connected to the bottom of the operating box 10, a first circular gear 15 is fixedly installed on the upper end of the turntable 14, four curved groove holes 141 are evenly opened in the clockwise direction on the upper surface of the turntable 14, eight L-shaped limiting rods 103 are fixedly installed at the four corners of the bottom of the operating box 10, four clamping rods 12 are slidably installed between the eight L-shaped limiting rods 103, four sliders 13 are fixedly installed at one end of the four clamping rods 12, the four sliders 13 are slidably installed in the four curved groove holes 141, and the other ends of the four clamping rods 12 are adapted to the annular clamping grooves 111.

[0028] In this embodiment, the four clamping rods 12 and the four sliding blocks 13 are symmetrically arranged about the central axis of the rotating disk 14 .

[0029] In this embodiment, a rotating rod 18 is rotatably installed between the two sides of the inner wall of the operating box 10. One end of the rotating rod 18 passes through the surface of the operating box 10 and is fixedly connected to a rocker 19. A threaded groove begins to form in the middle of the rotating rod 18, and a moving block 17 is strung on the threaded groove. The lower end of the moving block 17 is fixedly connected to a long tooth rod 16, which is meshed with the first circular gear 15.

[0030] Specifically, when measuring on an uneven road surface, the movable block 17 is rotated by manually rotating the rocker 19 to move on the threaded groove in the rotating rod 18, driving the long toothed rod 16 to move along the end direction of the rotating rod 18, so that the first circular gear 15 drives the turntable 14 to rotate counterclockwise, driving the four sliders 13 to slide in the four curved slots 141, pulling the four clamping rods 12 to slide in the eight L-shaped limit rods 103 away from the annular clamping grooves 111 in the four support rods 11, releasing the fixation of the four support rods 11, so that the four support rods 11 can extend different lengths from the four limit sleeves 102 according to the flatness of the ground, and at the same time adjust the horizontal bubble 101 on the support box 10 to the middle position. After the adjustment is completed, the rocker 19 is rotated in the opposite direction to make the four clamping rods 12 slide and engage in the annular clamping grooves 111 in the four support rods 11, and fix the four support rods 11, thereby facilitating the device to remain level on an uneven road surface and increasing the accuracy of measurement.

[0031] In this embodiment, the lower end of the support rod 11 is conical, and a limit block 112 is fixedly installed on the upper end of the support rod 11. The cross-section of the limit block 112 is larger than the cross-section of the limit sleeve 102 to prevent the device from being lifted excessively when adjusting the level, causing the four support rods 11 to fall out.

[0032] In this embodiment, the lifting mechanism includes a fixed sleeve rod 20 fixedly installed on the upper end of the operating box 10, and two connecting blocks 201 are fixedly connected to the inner walls of the upper end of the fixed sleeve rod 20. A threaded rod 22 is rotatably arranged in series in the two connecting blocks 201, and a first knob 23 is fixedly connected to one end of the threaded rod 22. A sliding rod 21 is slidably installed in the fixed sleeve rod 20, and a plurality of limiting circular holes 211 are evenly opened on one side of the sliding rod 21 close to the threaded rod 22, and the threaded rod 22 is adapted to the plurality of limiting circular holes 211.

[0033] Specifically, when the height of the device needs to be adjusted, the first knob 23 is turned to disengage the other end of the threaded rod 22 from the limiting circular hole 211 on the slide rod 21, and the fixing plate 30 is supported to drive the slide rod 21 to slide and rise in the fixed sleeve rod 20. When the required height is adjusted, the first knob 23 is turned in the opposite direction to rotate the other end of the threaded rod 22 into another limiting circular hole 211, thereby locking the slide rod 21 to facilitate adjusting the height of the device.

[0034] In this embodiment, the rotating assembly includes a fixed plate 30 fixedly mounted on the upper end of the slide rod 21, and two second circular gears 31 meshing with each other are rotatably mounted on the fixed plate 30. An operation box 301 is fixedly mounted above one of the second circular gears 31 on the fixed plate 30. A rotating shaft 35 is rotatably inserted into one side of the inner wall of the operation box 301. Two bevel gears 34 are respectively fixedly mounted on one end of the rotating shaft 35 and the upper end of one of the second circular gears 31. The two bevel gears 34 mesh with each other, and a second knob 36 is fixedly connected to the other end of the rotating shaft 35.

[0035] Furthermore, when measuring in different directions, by rotating the second knob 36, the two second circular gears 31 are rotated through the transmission of the rotating shaft 35 and the two bevel gears 34, so that the mounting seat 33 on the fixed circular rod 32 is rotated, so that the device can measure the land in different directions.

[0036] In this embodiment, the upper end of another second circular gear 31 is fixedly connected to a fixed round rod 32, and the upper end of the fixed round rod 32 is fixedly connected to a mounting seat 33, which is convenient for installing the distance measuring host.

[0037] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
