Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering structure measurement, in particular to a civil engineering structure deviation measurement device. Background Art

[0002] Nowadays, civil engineering generally refers to small civil engineering, including one-time construction of residential buildings, public buildings, structures, etc., such as precipitation, excavation, foundation, casting of columns, beams, slabs, walls and other enclosing structures, casting and masonry projects and their supporting steel bars, simple decorations, etc. In the process of civil engineering, a balanced weight well civil engineering structure deviation measuring device is needed to measure the deviation.

[0003] A current device for measuring deviation of civil engineering structure of a counterweight well, as described in the patent with publication number CN220230426U, comprises: a base plate, a horizontal mechanism is fixedly installed in the middle of the upper end of the base plate, a first fixed rod is fixedly connected to the left of the upper end of the base plate, two second fixed rods are fixedly connected to the right of the upper end of the base plate, the two second fixed rods are distributed front and back and do not touch, a controller is arranged in the middle of the front end of the second fixed rod, a plurality of control buttons are arranged at the lower part of the front end of the controller, a display screen is arranged at the upper part of the front end of the controller, a wire roller is movably connected to the upper part of the two second fixed rods, a motor is fixedly connected to the upper part of the front end of the second fixed rod, and a connecting wire is spirally wound on the outer surface of the wire roller.

[0004] With respect to the above-mentioned related technologies, the applicant believes that a device for measuring the deviation of the civil structure of a counterweight well uses an infrared measuring device and a connecting wire to measure the distance to the well wall in the well, and calculates the deviation with multiple sets of spacing data. However, in actual use, since there is only a connecting wire connected to the top of the infrared measuring device, the infrared measuring device shakes and rotates when it is lowered, resulting in the infrared measuring device being unable to accurately measure the well wall on the same vertical line, causing errors in the measurement data of the counterweight well and reducing the accuracy of the deviation measurement. Utility Model Content

[0005] The purpose of the utility model is to provide a device for measuring deviation of a civil engineering structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a civil engineering structure deviation measuring device, comprising: a fixed frame, a winding structure, a lifting structure and a weight block; the fixed frame is placed on the top ground of the counterweight well; the winding structure is arranged on the inner wall of the fixed frame, and the winding structure comprises a first twisted shaft rotatably connected to the inner wall of the fixed frame, two groups of first winding wheels welded on the outer wall of the first twisted shaft, a second twisted shaft rotatably connected to the inner wall of the fixed frame and two groups of second winding wheels welded on the outer wall of the second twisted shaft; the lifting structure is arranged on the upper surface of the fixed frame, and the lifting structure comprises two groups of horizontal rods welded to one end of the fixed frame, a first pulley rotatably connected to one end of the horizontal rod, two groups of inclined rods welded to the upper surface of the fixed frame, a second pulley rotatably connected to the top of the inclined rod and a rope wound around the first winding wheel and the second winding wheel; one end of the rope passes through the second pulley, the weight block and the first pulley in sequence, and the outer wall of the rope clamps the measuring structure.

[0007] By adopting the above technical solution, by utilizing two sets of horizontal rods and inclined rods, the weight block can be vertically lowered to the bottom of the well to form a straight moving track by using ropes and pulleys. After the measuring structure is clamped on the rope near the second pulley, it is moved stably on two ropes vertically pulled by the weight block, which can avoid the problem of rotation during descent, improve the stability of the measuring structure during descending measurement, and thus improve the accuracy of the measurement data of the balance weight well.

[0008] Preferably, a wire hole is opened at the bottom end of the inclined rod, one end of the rope passes through the wire hole and is wound around the second winding wheel, and the horizontal rod and the inclined rod are in the same plane.

[0009] By adopting the above technical solution, the wire hole is opened to ensure that the rope is wound onto the second winding wheel in a straight line to reduce the friction between the rope and other objects. When lowering the weight block, the rope on the second winding wheel can be released smoothly to ensure that the weight block can fall vertically to the bottom of the well.

[0010] Preferably, the measuring structure includes a cross bar arranged on the outer wall of the rope, a clip pressed on one end of the cross bar, a bolt threadedly connected to one side of the clip and a horizontal tube arranged on the upper surface of the cross bar, and the rope is located between the cross bar and the clip.

[0011] By adopting the above technical solution, the rope can be clamped at one end of the cross bar by using clips and bolts. When the two ends are respectively clamped on the two ropes, the measurement structure can be stably maintained in a vertical state and descended to measure the well wall under the connection of the two ropes and the cross bar, which can avoid the deviation of the measuring point position caused by rotation during measurement, thereby improving the accuracy of measurement.

[0012] Preferably, the measuring structure further comprises an infrared measuring device arranged on the lower surface of the cross bar and a receiving controller adhered to the outer wall of the cross bar.

[0013] By adopting the above technical solution, by installing an infrared measuring device at the bottom of the crossbar, it can be vertically lowered on the rope following the stable crossbar to ensure stable measurement of the well wall on the vertical line, thereby improving the accuracy of the measurement.

[0014] Preferably, a round rod is provided on the top of the load-bearing block, and one end of the rope passes through the round rod and the rope of the measuring structure section is always in a vertical state.

[0015] By adopting the above technical solution, a round rod is used to pass the rope through the weight block, and a rope much longer than the well depth is pulled out from the second winding wheel for use. The weight block on the rope is lowered with the second pulley as the vertical point, and the weight block will fall vertically to the bottom of the well. At this time, the first and second winding shafts are wound to straighten the rope, and the installed measuring structure can maintain stable descent measurement as the rope descends.

[0016] Preferably, the positions of the two groups of horizontal rods and oblique rods correspond to the positions of the first winding wheel and the second winding wheel, and the length of the oblique rods extending in the horizontal direction is greater than the length of the horizontal rods.

[0017] By adopting the above technical solution, the design of the structure can ensure that the two ropes on each structure work in a synchronous state, so as to achieve the same effect of releasing and winding up, so as to keep the horizontal state of the crossbar after horizontal adjustment and lowering, so as to improve the stability of the measurement state.

[0018] Preferably, the wheelbase length of the first pulley and the second pulley is the same as the width of the rope.

[0019] By adopting the above technical solution, the wheel spacing of the first pulley and the second pulley for placing the rope are set respectively, and the rope can pass through this distance as much as possible, which is used to limit the horizontal movement position of the rope when it is released, reduce the amplitude of horizontal shaking of the released rope, and thus improve the stability of the infrared measuring instrument when it is descended, so as to measure the well wall deviation in a horizontally stable state.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] By using two sets of horizontal rods and inclined rods, the weight block can be vertically lowered to the bottom of the well to form a straight moving track under the action of ropes and pulleys. After clamping the upper measuring structure on the rope near the second pulley, the winding structure is used to wind up the rope, and the two ropes pulled vertically by the weight block are used for stable movement, which can avoid the problem of rotation during descent, improve the stability of the measuring structure during descent measurement, and thus improve the accuracy of the measurement data of the counterweight well;

[0022] The rope can be clamped at one end of the cross bar by using clips and bolts. When the two ends are clamped on the two ropes respectively, the infrared measuring device can be kept in a vertical state and descended to measure the well wall under the connection of the two ropes and the cross bar, which can avoid the deviation of the measuring point position caused by rotation during measurement, thereby improving the accuracy of measurement.

The wire hole 304 is provided to ensure that the rope 306 is wound around the second winding wheel 204 in a straight line to reduce the friction between the rope 306 and other objects. When the load block 4 is lowered, the rope on the second winding wheel 204 can be released smoothly to ensure that the load block 4 can fall vertically to the bottom of the well. The measuring structure 5 includes a cross bar 501 arranged on the outer wall of the rope 306, and a cross bar 501 pressed on one side of the cross bar 501.
