Description

Technical Field

[0001] The utility model relates to the technical field of plumb bobs, in particular to a plumb bob for horizontal and vertical detection in civil engineering. Background Art

[0002] The instrument commonly used for measuring vertical conditions is a plumb bob. It uses a fixed frame or directly fixes the upper end of the hanging wire by hand. The plumb bob moves vertically downward under the action of gravity to determine the verticality of other objects, walls, etc.

[0003] However, in the prior art, the laser light of the dual-purpose plumb bob used for horizontal and vertical detection can only emit light downwards, which is not convenient for horizontal measurement of building components at high places and has limitations. In addition, common plumb bobs require manual retraction and extension of the hanging wire, and the piled hanging wires are prone to entanglement and knotting. Therefore, we propose a dual-purpose plumb bob for horizontal and vertical detection in civil engineering. Utility Model Content

[0004] The utility model provides a double-purpose plumb bob for horizontal and vertical detection in civil engineering, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problems with the following solution: a dual-purpose plumb bob for horizontal and vertical detection in civil engineering, comprising a fixed box, a winding wheel being installed in the fixed box for horizontal rotation, the winding wheel being connected to a rotation control mechanism, a plumb bob being vertically arranged below the fixed box, a laser lamp being fixedly embedded on the tip of the lower part and the upper end face of the plumb bob respectively, a reference plate being fixedly installed in the lower part of the plumb bob for horizontal rotation, a connecting piece with an I-shaped cross section being fixedly installed in the middle part of the upper end face of the plumb bob, the connecting piece being fixedly connected to the winding wheel through a hanging wire, a slot penetrating through the fixed box is provided on the lower wall of the fixed box, a semicircular fixing piece is slidably fitted on the inner bottom face of the fixed box, and the fixing piece is connected to a movement control mechanism.

[0006] Preferably, the rotation control mechanism comprises a small motor which is laterally fixedly installed in a fixed box, and the output shaft of the small motor is fixedly connected to the shaft of the winding wheel.

[0007] Preferably, the movement control mechanism comprises a screw rod which is laterally rotatably mounted on the outer side wall of the fixing member, the screw rod thread passes through the side wall of the fixing box, and a knob is fixedly mounted on the end of the screw rod.

[0008] Preferably, the upper portion of the connecting piece is truncated cone-shaped, and the connecting piece fits in a groove on the lower wall of the fixing box.

[0009] Preferably, the upper surface of the plumb bob is smoothly arranged, and the outer diameter of the reference plate is the same as the outer diameter of the plumb bob.

[0010] The beneficial effects of the utility model are:

[0011] 1. Two additional laser lights are set on the upper end of the plumb bob to emit lasers upwards, and the manually placed reflector plates above are used to measure high-rise building components. The reflection of the laser can be used to determine whether the high-rise building components are level, which is more functional.

[0012] 2. By setting a small motor to drive the winding wheel to rotate, the hanging wire can be automatically wound and retracted. After the hanging wire bob and the fixing box are tightly pressed against each other, the screw can be rotated to control the movement of the fixing part, so that the fixing part and the connecting part are combined to limit and fix the hanging wire bob. This can not only prevent the hanging wire from being scattered, but also facilitate the storage of the device.

[0013] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiment of the utility model with the accompanying drawings.

The screw 10 is rotated to control the movement of the fixing piece 8, so that the fixing piece 8 fits with the middle part of the connecting piece 6, and the connecting piece 6 is limited and fixed, thereby fixing the hanging wire bob 3.

After the plumb bob 3 is stable, measurement is performed. When performing vertical measurement of the building, it can be directly compared with the hanging wire 7 for observation, and horizontal measurement of the ground or high-rise building components can be performed. A reflector can be manually placed on the surface of the building component or on the ground to determine whether the laser reflected by the reflector coincides with the laser light 4, so as to determine whether it is level.
