Description

Technical Field

[0001] The invention relates to the technical field of measuring equipment, and in particular to a movable measuring device for building construction. Background Art

[0002] Engineering surveying instruments for construction refer to a series of precision measuring equipment used in the construction process to ensure the accuracy and quality of the construction. These instruments can help measure and monitor the location, height, angle, distance and other key dimensions of the building to ensure that the construction is carried out in accordance with the design drawings and specifications.

[0003] In the prior art, engineering surveying instruments used in construction are divided into fixed surveying instruments and surveying instruments equipped with rotating parts. The angle of fixed surveying instruments is not easy to adjust, and the measuring bracket needs to be rotated as a whole, which is very inconvenient. The surveying instruments equipped with rotating parts will produce wear after long-term use, which may be caused by aging of bearings, wear of gears, insufficient lubrication or failure of the locking mechanism. This will not only reduce the measurement efficiency, but also may lead to inaccurate measurement data, thereby affecting the quality and safety of the entire construction project. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a mobile construction measurement device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a surveying device for construction that is easy to move, comprising a surveying instrument, a connecting seat is provided at the bottom of the surveying instrument, a measuring bracket is rotatably connected to the circumferential array of the connecting seat, an adjustment bracket is slidably connected to the inner wall of the measuring bracket, a limiting frame is fixed to the top of the connecting seat, the limiting frame passes through the bottom of the surveying instrument, and the limiting frame is rotatably connected to the bottom of the surveying instrument, both sides of the top of the limiting frame are rotatably connected to limiting members, the limiting member is set as a cylinder, and a rotating handle is fixed to the circumferential surface of the limiting member.

[0006] Preferably, the measuring bracket side wall array is provided with adjustment holes, and limiting grooves are provided on both sides of the adjusting bracket. The inner walls of the limiting grooves are slidably connected to limiting columns, and a limiting spring is fixed between one side of the limiting column and the inner wall of the limiting groove. The existing measuring bracket mainly controls the extension and retraction of the bracket by rotating the surface knob, and the adjustment speed is slow. To solve this problem, the present invention adopts a quick adjustment mechanism, which cooperates with the limiting column and the limiting spring bracket to move the adjusting bracket according to the adjustment length, so that the limiting columns on both sides of the adjusting bracket are engaged with the limiting grooves corresponding to the side walls of the measuring bracket. The operation is simple, the adjustment is convenient, the adjustment speed is fast, and the structure is simple and easy to maintain.

[0007] Preferably, the other side of the limit column is set to be hemispherical, so as to reduce the friction between the limit column and the side wall of the measuring bracket, and facilitate the sliding of the adjustment bracket inside the measuring bracket.

[0008] Preferably, a slide groove is provided at the bottom of the adjusting bracket, and a conical rod is slidably connected to the inner wall of the slide groove, the bottom of the conical rod is set to be conical, and the top of the conical rod is threadedly connected to a screw, a spur bevel gear is fixed on the top of the screw, the spur bevel gear is rotatably connected to the top surface of the slide groove, a secondary bevel gear is meshed with the surface of the spur bevel gear, and an adjusting knob is fixed on the side of the secondary bevel gear, and the adjusting knob is rotatably connected to the adjusting bracket, and a universal wheel is fixed to the bottom end of the adjusting bracket. The conical column at the bottom of the existing measuring bracket is mainly used to support the ground. Due to the conical design, it is inconvenient to carry. To solve this problem, the present invention adopts a retractable conical column, which drives the secondary bevel gear to rotate through the adjusting knob, thereby driving the spur bevel gear to rotate, and the spur bevel gear drives the screw to rotate, thereby driving the conical rod to slide in the slide groove, which is easy to carry.

[0009] Preferably, the surface array of the adjusting knob is provided with anti-slip grooves to facilitate the staff to turn the adjusting knob.

[0010] Preferably, the limiting member is covered with a rubber sleeve around it, which reduces the loss between the limiting member and the measuring instrument, while improving the tightness between the limiting member and the measuring instrument, so as to facilitate long-term use.

[0011] Preferably, the spacings between adjacent adjustment holes are equal, so as to facilitate the control of the adjustment length.

[0012] Beneficial Effects In the prior art, engineering surveying instruments for construction are divided into fixed surveying instruments and surveying instruments equipped with rotating parts. The angle of the fixed surveying instrument is not easy to adjust, and the measuring bracket needs to be rotated as a whole, which is very inconvenient. The surveying instrument equipped with rotating parts will produce wear after long-term use, which may be caused by aging of bearings, wear of gears, insufficient lubrication or failure of the locking mechanism, which will not only reduce the measurement efficiency, but also may cause inaccurate measurement data, thereby affecting the quality and safety of the entire construction project. In view of such problems, the present invention adopts a new adjustment mechanism, the limit member and the limit frame are eccentrically connected, the connecting shaft deviates from the middle of the limit member, and the angle of the measuring instrument is adjusted according to the measured object. After the adjustment is completed, the rotary handle is rotated to rotate the limit member around the connecting shaft until the limit member is engaged with the measuring surface, thereby fixing the measuring instrument to prevent it from shaking during the measurement process. Moreover, under the protection of the rubber sleeve, the loss between the limit member and the measuring instrument is reduced, and the tightness between the limit member and the measuring instrument is improved, which is convenient for long-term use.

[0018] The side wall array of the measuring bracket 3 is provided with adjustment holes 301, and the spacing between adjacent adjustment holes 301 is equal, which is convenient for adjusting the adjustment length. Limiting grooves are provided on both sides of the adjusting bracket 4, and the inner wall of the limiting groove is slidably connected to the limiting column 11, and the limiting spring 12 is fixed between one side of the limiting column 11 and the inner wall of the limiting groove. The existing measuring bracket 3 mainly controls the extension and contraction of the bracket by rotating its surface knob, and the adjustment speed is slow. In view of such problems, the present invention adopts a quick adjustment mechanism, through the cooperation of the limiting column 11 and the limiting spring 12 bracket, so as to move the adjusting bracket 4 according to the adjustment length, so that the limiting columns 11 on both sides are engaged with the limiting grooves corresponding to the side walls of the measuring bracket 3, which is simple to operate, convenient to adjust, fast to adjust, and simple in structure, and easy to maintain. The other side of the limiting column 11 is set to be hemispherical, which reduces the friction between the limiting column 11 and the side wall of the measuring bracket 3, and facilitates the sliding of the adjusting bracket 4 in the measuring bracket 3.

[0019] A slide groove is provided at the bottom of the adjustment bracket 4, and a conical rod 10 is slidably connected to the inner wall of the slide groove. The bottom of the conical rod 10 is set to be conical, and a screw 9 is threadedly connected to the top of the conical rod 10. A positive bevel gear 7 is fixed on the top of the screw 9.
