Description

Technical Field

[0001] The utility model belongs to the technical field of perpendicularity detection, and particularly relates to a perpendicularity detection device for building construction. Background Art

[0002] As is well known, in building construction, perpendicularity detection is very important to ensure that the perpendicularity of the building structure meets the design requirements. It can help construction workers accurately measure and adjust the perpendicularity of the building structure, ensuring the quality and safety of the building.

[0003] In the utility model patent with the patent authorization announcement number CN220690126U, a perpendicularity detection device for building construction is disclosed. The perpendicularity detection device for building construction includes: a base box; an installation box slidably installed on the base box; a plumb line rotatably installed in the installation box, with a plumb bob provided at the bottom end of the plumb line; a rotating motor fixedly installed on one side of the installation box, the output shaft of the rotating motor passing through the installation box and fixedly connected to the plumb line; a rangefinder slidably installed on the installation box; and a height adjustment mechanism provided on the base box for adjusting the detection device.

[0004] However, the existing perpendicularity detection devices for building construction also have certain deficiencies. First of all, most of the existing perpendicularity detection devices for building construction use a manual shaking method to wind and unwind the traction line, which is obviously inconvenient for construction workers to operate.

[0005] Secondly, most of the existing perpendicularity detection devices for building construction simply use avoidance holes to thread the traction line. Due to factors such as flexible friction, the traction line will be worn after long-term use, and then the structural strength of the traction line will become weak. Summary of the Invention

[0006] The purpose of the utility model is to provide a perpendicularity detection device for building construction, which solves the problem that most of the existing perpendicularity detection devices for building construction use a manual shaking method to wind and unwind the traction line, making it inconvenient for construction workers to operate; and solves the problem that most of the existing perpendicularity detection devices for building construction simply use avoidance holes to thread the traction line. Due to factors such as flexible friction, the traction line will be worn after long-term use, and then the structural strength of the traction line will become weak.

[0007] To achieve the above object, the utility model provides a verticality detection device for building construction, including a housing. A handle is fixedly connected to the upper side of the housing. A housing cover is arranged on the front surface of the housing. A servo motor is fixedly installed on the back surface of the housing. The output shaft of the servo motor is rotatably connected to the housing. A winding wheel is fixedly sleeved on the outer side of the output shaft of the servo motor. A traction wire is arranged on the surface of the winding wheel. A plumb bob is fixedly connected to the lower end of the traction wire. A lubricating cylinder is fixedly connected inside the housing. The lubricating cylinder is in contact with the traction wire. A guiding mechanism is jointly arranged on the housing and the output shaft of the servo motor. A lubricating mechanism is arranged inside the lubricating cylinder.

[0008] The principle of the utility model is as follows: Start the servo motor to drive the output shaft to rotate, which can drive the winding wheel to rotate forward and backward, automatically wind and unwind the traction wire, and perform the winding and unwinding process on the plumb bob, facilitating the construction personnel to use for verticality detection of building construction. When the output shaft of the servo motor rotates, it can drive the fixed cylinder to rotate, so as to drive the telescopic rod to rotate, and finally drive the limiting piece to rotate along the inner side wall of the limiting ring groove, performing rotational limitation on the output shaft of the servo motor to avoid the jitter problem of the winding wheel. Under the deformation action of the elastic member, it can push the fixed disk to drive the telescopic rod to move, so that the limiting piece is always in contact with the inner side wall of the limiting ring groove to ensure a good limiting effect of the limiting piece.

[0009] By pulling the end plate to move to the left, the connecting wire is driven to move, and the plug is traction-treated. The spring deforms, and finally the plug is separated from the sealing plate, making the oil injection cylinder in a flowing state, facilitating the construction personnel to add lubricating oil. Under the action of the oil-absorbing sponge, the lubricating oil can be adsorbed, and finally the lubricating oil contacts the moving traction wire to lubricate the traction wire and avoid the problem of flexible friction damage of the traction wire.

[0010] The beneficial effects of the utility model are as follows: In this scheme, the servo motor drives the winding wheel to wind and unwind the traction wire, and then winds and unwinds the plumb bob to complete the verticality detection of building construction. Under the action of structures such as the limiting ring groove, the limiting piece, and the telescopic rod, rotational limitation can be performed on the output shaft of the servo motor to ensure that the output shaft of the servo motor drives the winding wheel to rotate stably. By pulling the end plate to move to the left, the connecting wire is driven to move, the spring deforms, and finally the plug is separated from the sealing plate, facilitating the user to add lubricating oil to the lubricating cylinder. Under the action of the oil-absorbing sponge, the lubricating oil can be adsorbed, and then the traction wire is lubricated to avoid the problem of flexible friction damage of the traction wire.

[0011] Furthermore, the guiding mechanism includes a limiting ring groove. The inner wall of the housing is provided with a limiting ring groove. The output shaft of the servo motor is fixedly connected with a fixed cylinder. A telescopic rod is slidably connected inside the fixed cylinder. The end face of the telescopic rod away from the fixed cylinder is fixedly connected with a limiting piece. The limiting piece contacts the limiting ring groove. A fixed disk is fixedly sleeved on the outer side of the telescopic rod. An elastic member is adhesively connected to the end face of the fixed disk close to the fixed cylinder. The other end of the elastic member is adhesively connected to the fixed cylinder. Through the action of structures such as the limiting ring groove and the limiting piece, the rotation of the output shaft of the servo motor can be limited, avoiding the problem of the servo motor driving the winding wheel to shake. And under the deformation action of the elastic member, the limiting piece can always contact the limiting ring groove to ensure the limiting effect on the output shaft of the servo motor.

[0012] Furthermore, there are four fixed cylinders. The four fixed cylinders are arranged in a circular array on the output shaft of the servo motor. Through the setting of the fixed cylinders, it is convenient for the subsequent installation and use of structures such as the telescopic rod.

[0013] Furthermore, there are multiple elastic members. The multiple elastic members are symmetrically distributed on the fixed disk. Through the setting of the elastic members, the fixed disk can be connected and used.

[0014] Furthermore, the lubricating mechanism includes an oil-absorbing sponge. The inner side wall of the lubricating cylinder is fixedly connected with an oil-absorbing sponge. The oil-absorbing sponge contacts the traction wire. An oil injection cylinder is fixedly connected inside the lubricating cylinder. A sealing disk is fixedly connected to the inner wall of the oil injection cylinder. A plug is slidably connected to the inner wall of the sealing disk. The left end of the oil injection cylinder contacts an end disk. A connecting wire is fixedly connected to the right end of the end disk. The connecting wire is fixedly connected to the plug. By pulling the end disk to move to the left, the connecting wire is driven to move, and then the plug is pulled to move. Finally, the plug is separated from the sealing disk, which is convenient for construction personnel to add lubricating oil. And under the action of the oil-absorbing sponge, the lubricating oil can be adsorbed and then the traction wire can be lubricated.

[0015] Furthermore, the overall shape of the end disk is elliptical. The end disk is made of PVC material. Through the setting of the end disk, it is convenient for construction personnel to pull the connecting wire to move, and the PVC material has good lightness.

[0016] Furthermore, a spring is fixedly connected to the right end of the plug. The other end of the spring is welded to the end block of the oil injection cylinder. Through the setting of the spring, the plug can be connected and used. BRIEF DESCRIPTION OF THE DRAWINGS
