Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction equipment, in particular to a three-dimensional laser scanner lifting bracket for a deep foundation pit. Background Art

[0002] At present, when monitoring the deformation of foundation pits, three-dimensional laser scanners are usually used to study the deformation of support structures. The existing three-dimensional laser scanners include a three-dimensional laser scanner body, which is fixed on a tripod. The height is mainly adjusted by the inclination angle of the tripod, and then the scanning stroke of the three-dimensional laser scanner in the vertical direction is adjusted to search the concave surface of the support structure. However, when it comes to deeper foundation pits, when the depth exceeds 20 meters, the height of ordinary tripods is limited and can only meet the scanning needs of shallower foundation pits. In addition, there are many on-site objects in the foundation pit. When the height of the tripod is adjusted, the stability of the tripod is insufficient. In addition, the weight of the three-dimensional laser scanner itself is not large, so the tripod is easy to deflect or even fall over, resulting in large deviations in the data measurement of the foundation pit support structure.

[0028] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0030] See also Figure 1 , Figure 2 and Figure 3 When measuring data of each foundation pit support structure in a deeper foundation pit, due to the deeper foundation pit, the general fixed bracket cannot adapt to the measurement of the deeper foundation pit. There is a higher bracket, which is inconvenient to adjust the height of the bracket. Therefore, the utility model proposes a lifting bracket for a three-dimensional laser scanner for a deep foundation pit, including a fixed pipe 100, which is vertically arranged on a base 200; a lifting pipe 300, which is vertically slidably arranged in the tube cavity of the fixed pipe 100; a lifting drive mechanism, which drives the lifting pipe 300 to move along the fixed pipe 100; a fixed end 310, which is installed at the upper end of the lifting pipe 300 and is used to install a three-dimensional laser scanner body 400; a supporting bracket 500, which is arranged in multiple groups along the circumferential direction of the lower end of the fixed pipe 100, one end of the supporting bracket 500 is hinged to the lower end of the fixed pipe 100, and the hinge axis of the supporting bracket 500 is horizontal and perpendicular to the length direction of the fixed pipe 100; and an adjustment mechanism is used to adjust the angle between the supporting bracket 500 and the fixed pipe 100.

[0031] In one embodiment, when the lifting bracket is actually used, the three-dimensional laser scanner body 400 is fixed at the fixed end 310 position, and the lifting drive mechanism is started to move the lifting tube 300 along the fixed tube 100, so as to adjust the height of the fixed end 310 at the upper end of the lifting tube 300. The adjustment of the height of the three-dimensional laser scanner body 400 can adapt to the measurement of various foundation pit support structure data of deeper foundation pits, and the angle between the supporting bracket 500 and the fixed tube 100 is adjusted by the adjustment mechanism, so as to adjust the projection of the supporting bracket 500 in the vertical direction, and then according to the height of the lifting tube 300, the angle between the supporting bracket 500 and the fixed tube 100 is adjusted. When the height of the lifting tube 300 is high, the adjustment mechanism adjusts the angle between the supporting bracket 500 and the fixed tube 100 to be larger to enhance the stability of the lifting bracket. When the height of the lifting tube 300 is high, the adjustment mechanism adjusts the angle between the supporting bracket 500 and the fixed tube 100 to be smaller to reduce the occupancy submission of the lifting bracket and facilitate transportation.

[0032] In one embodiment, the support brackets 500 are arranged in three groups at intervals along the circumferential direction of the lower end of the fixing pipe 100 .

[0033] In one embodiment, in order to ensure that the entire lifting bracket is reliably fixed to the ground and avoid tipping during construction, a fixed drill rod 600 is provided on the support bracket 500. The fixed drill rod 600 is arranged vertically and plugged into the base surface.

[0034] In one embodiment, in order to guide the lifting and lowering of the lifting tube 300 in the fixed tube 100, the inner wall of the fixed tube 100 is provided with a protrusion 110, and the protrusion 110 is arranged along the length direction of the fixed tube 100.

The lifting screw rod 330 is located in the tube cavity of the lifting tube 300 and arranged along the length direction.

[0036] In one embodiment, by starting the lifting screw 330 to rotate, the lifting tube 300, with the cooperation of the protrusion 110 and the slide groove, slides along the slide groove, and then implements sliding guidance of the lifting tube 300, so that the three-dimensional laser scanner body 400 can have a larger range of adjustment space in the vertical space to adapt to the surveying and mapping of deep foundation pits.

[0038] When the lifting screw 330 is rotated, the driving motor 333 is started to rotate the second bevel gear 332, thereby driving the first bevel gear 331 to rotate, so as to rotate the lifting screw 330, and the lifting screw 330 is rotationally supported by the support bearing 340 to lift and lower the three-dimensional laser scanner body 400.

[0039] In one embodiment, a battery is installed on the base 200 , and the battery can supply power to the driving motor 333 through a wire.

[0041] In one embodiment, during actual use, the lifting bracket is placed on the ground and combined with the ground by the fixed drill rod 600. By rotating the fixed drill rod 600, the depth of combination of the fixed drill rod 600 and the ground can be implemented, thereby improving the stability of the entire supporting tripod 500 and the ground. In addition, the horizontality of the three-dimensional laser scanner body 400 can also be adjusted by rotating the fixed drill rod 600.

[0042] In actual use, a level is provided on the outer wall of the fixing tube 100 , and the level is used to determine whether the lifting bracket is adjusted to a horizontal state. When the entire lifting bracket is horizontal, the rotation of the fixing drill rod 600 can be stopped.
