DETAILED DESCRIPTION

[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 8 As shown, a high-precision laser measuring device for land planning includes a laser measuring device body 1, connecting plates 2 are fixedly installed on both sides of the lower surface of the laser measuring device body 1, T-shaped slots 3 are penetrated through the surface of one side of the two connecting plates 2, T-shaped blocks 4 are slidably arranged in the two T-shaped slots 3, and a supporting seat 5 is fixedly installed on the lower surface of the T-shaped block 4. A positioning component 6 for positioning is arranged on the lower surface of the supporting seat 5.

[0037] The positioning assembly 6 includes two support plates 601 , which are respectively arranged on both sides of the lower surface of the support seat 5 . Two support blocks 602 are arranged on the lower surface of the two support plates 601 , and a vacuum suction cup 603 is arranged on the lower surface of each support block 602 .

[0038] Through the above technical solution, the staff holds the laser measuring device body 1, aligns the T-slot 3 with the corresponding T-block 4, and then inserts it to connect the support seat 5 with the laser measuring device body 1. Then the staff uses the vacuum suction cup 603 to fix the laser measuring device body 1 and the support seat 5 on the roof, which is convenient for the staff to measure the distance on the vehicle. There is no need to use ropes and tapes to bind the laser measuring device body 1 to the vehicle. The operation process is convenient and does not require much time and effort, which greatly improves work efficiency.

[0039] In this embodiment, a moving groove 7 is formed on the lower surface of the support seat 5, and two moving blocks 8 are slidably arranged in the moving groove 7. The lower surfaces of the two moving blocks 8 are fixedly connected to the corresponding support plates 601 respectively;

[0040] A first bidirectional threaded rod 9 is rotatably mounted between the two sides of the inner wall of the moving groove 7, and two moving blocks 8 are respectively threadedly arranged on the two sides of the rod body of the first bidirectional threaded rod 9;

[0041] One end of the first bidirectional threaded rod 9 passes through the movable groove 7 and is fixedly mounted with a connecting wheel 10 .

[0042] The staff rotates the connecting wheel 10 to drive the first bidirectional threaded rod 9 to rotate, and the two moving blocks 8 move relatively along the moving groove 7, so that the two vacuum suction cups 603 move along the direction of the moving groove 7, which makes it convenient for the staff to adjust the position of the vacuum suction cup 603 according to the area of ​​the installation position, thereby improving the flexibility during installation.

[0043] It can be understood that in the present application, the lower surfaces of the two support plates 601 are provided with a slide groove 11, and two sliders 12 are slidably arranged in the two slide grooves 11, and the lower surface of each slider 12 is fixedly connected to the corresponding support block 602;

[0044] A second bidirectional threaded rod 13 is rotatably mounted between the inner walls of the two slide grooves 11, and adjacent sliders 12 are respectively threadedly arranged on both sides of the corresponding second bidirectional threaded rod 13;

[0045] One end of the two second bidirectional threaded rods 13 passes through the corresponding sliding slots 11 and is fixedly mounted with a rotating wheel 1301 .

[0046] The staff rotates the rotating wheel 1301 to rotate the second bidirectional threaded rod 13, and the adjacent sliders 12 move relatively along the corresponding slide grooves 11, so that the vacuum suction cup 603 can move along the direction of the slide groove 11, further improving the flexibility during installation.

[0047] It can be understood that in the present application, a protective cover 14 is fixedly mounted on the upper surface of the support seat 5 , a first through slot 15 is penetrated through one side surface of the inner wall of the protective cover 14 , and a second through slot 16 is penetrated through the inner top surface of the protective cover 14 .

[0048] Two cover plates 17 are provided on the upper surface of the protection cover 14 .

[0049] By providing the protective cover 14 and the cover plate 17 , when the staff performs vehicle-mounted work, the protective cover 14 and the cover plate 17 can protect the laser measuring device body 1 , and by providing the first through slot 15 , the laser measuring device body 1 can enter the protective cover 14 conveniently.

[0050] It can be understood that in the present application, mounting grooves 18 are provided on both sides of the upper surface of the protective cover 14, and two mounting blocks 19 are slidably provided in the two mounting grooves 18, and the upper surfaces of the two mounting blocks 19 are fixedly connected to the corresponding cover plates 17 respectively;

[0051] A mounting rod 20 is fixedly installed between the two inner walls of the two mounting grooves 18 , and adjacent mounting blocks 19 are slidably arranged on both sides of the corresponding mounting rod 20 .

[0052] A bracket 21 is fixedly mounted on one side of the two cover plates 17, and a rack 22 is disposed on the opposite side of the two brackets 21. The two racks 22 are disposed in layers;

[0054] The staff rotates the hand wheel 25 to drive the gear 24 to rotate. Under the meshing action of the gear 24 and the rack 22, the two cover plates 17 move away from each other, making it convenient for the staff to operate the control panel of the laser measuring device body 1 through the second through slot 16.

[0055] It can be understood that in the present application, a baffle 26 is provided on one side of the two connecting plates 2 .

[0056] The two baffles 26 are fixed and installed correspondingly on one side of the connecting plate 2 by butterfly bolts 27 .

[0057] By connecting the baffle plate 26 to the connecting plate 2 through the butterfly bolts 27 , the T-block 4 can be fixed in the T-slot 3 , thereby preventing the support base 5 from being separated from the laser measuring device body 1 when the vehicle is driving.

[0058] The working principle of a high-precision laser measurement device for land planning:

[0059] When in use, first, the staff holds the laser measuring device body 1, aligns the T-slot 3 with the corresponding T-block 4, and then inserts it to connect the support seat 5 with the laser measuring device body 1. Then the staff uses the vacuum suction cup 603 to fix the laser measuring device body 1 and the support seat 5 on the roof, which is convenient for the staff to measure the distance on the vehicle. There is no need to use ropes and tapes to bind the laser measuring device body 1 to the vehicle. The operation process is convenient and does not require much time and effort, which greatly improves work efficiency.

[0060] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
