Description

Technical Field

[0001] The utility model relates to the field of lifting devices, in particular to a camera assembly lifting device for a 3D wheel calibration machine. Background Art

[0002] 3D four-wheel calibration machine, full name 3D digital imaging four-wheel calibration machine, is a device used to test the wheel alignment parameters of a car. According to the different diameters of the wheels, in order to achieve the corresponding comprehensive detection, the lifting device is used to drive the whole to a suitable position. The 3D four-wheel calibration machine installs four target reflectors on the four rims of the vehicle, rolls the wheels, and the camera continuously shoots the geometric figures on the target reflectors. According to the lifting height requirements, the lifting and lowering are adjusted through the columns to meet the height requirements and achieve the shooting position corresponding to the vehicle body. Since the horizontal beam is usually lifted and lowered along the longitudinal beam, it is easy to become unstable and shake as it rises and falls along the edge, reducing the stability of the camera shooting; therefore, we propose a camera assembly lifting device for a 3D wheel calibration machine to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the existing camera assembly lifting device of the 3D wheel calibration machine, since the horizontal beam is usually lifted and lowered along the longitudinal beam, it is easy to become unstable and shake along the rise and fall along the edge.

[0004] The technical solution of the utility model is: a camera assembly lifting device for a 3D wheel calibration machine, including a control box, a lifting crossbeam, a sleeve longitudinal beam, a reflective hanging module, a control display screen and a pulling adjustment component; both sides of the control box are provided with a reflective hanging module for positioning and connecting to facilitate camera observation, the upper end of the control box is provided with a control display screen for controlling the overall adjustment parameters, the rear of the control box is provided with a sleeve longitudinal beam for connection, and a lifting crossbeam for adjusting displacement is provided in the middle of the sleeve longitudinal beam.

[0005] Preferably, as the control motor drives the variable pitch module to drive the lifting beam along the slide groove on the sleeve longitudinal beam to perform rising and falling adjustment, automatic speed change transmission and efficient energy conversion are realized, thereby improving the efficiency of mechanical transmission. As the lifting beam rises, the steel wire rope on the winding roller is in a pulling state through magnetic attraction, and the synchronous drive motor drives the winding roller to perform the winding operation. With each rise of the lifting beam, changes occur on the horizontal bubble ruler. You only need to observe the deviation to make timely adjustments, thereby increasing the rapid deviation correction performance.

[0006] Preferably, both ends of the lifting beam are provided with transverse cameras for observation, the outer side of the transverse camera is provided with a protective shock-absorbing cover, the surface of the lifting beam is fitted with a horizontal bubble ruler, and the outer side of the lifting beam is provided with a protective cover. With each rise of the lifting beam, changes occur on the horizontal bubble ruler. Only by observing the deviation can timely adjustments be made, thereby increasing the rapid deviation correction performance.

[0007] Preferably, a signal transmitter is provided inside the horizontal camera, and a light sensor is provided in a circular direction on the outer end of the horizontal camera. The synchronized light sensor can assist the horizontal camera to capture light in a timely manner and improve observation performance.

[0008] Preferably, a sliding groove for sliding the lifting beam is provided in the middle of the sleeve longitudinal beam, a variable pitch module for controlling the lifting and lowering adjustment of the lifting beam is provided inside the sleeve longitudinal beam, a control motor for controlling the variable pitch module is provided on the sleeve longitudinal beam, a shock-absorbing plate is provided at the front end of the sleeve longitudinal beam, a top camera is provided at the top of the sleeve longitudinal beam, and a shock-absorbing base is provided at the bottom of the sleeve longitudinal beam. As the control motor drives the variable pitch module to drive the lifting beam along the sliding groove on the sleeve longitudinal beam, it is adjusted to rise and fall.

[0009] Preferably, the pulling adjustment component includes a wire rope, an adjusting bolt, a connecting rod, a magnetically matched winding roller, a connecting box, a winding roller, a synchronous control module, a synchronous controller and a driving motor. There are two groups of connecting rods, and the two groups of connecting rods are distributed and run through the lifting beam. There are two groups of winding rollers, and the two groups of winding rollers are located on the sleeved longitudinal beam and are arranged separately. The wire rope is connected between the winding roller and the connecting rod. As the lifting beam rises and falls, the wire rope is connected between the winding roller and the connecting rod, thereby increasing the two-way connection performance.

[0010] Preferably, a magnetically-matched winding roller is provided at one end of the connecting rod, and the adjusting bolt is movably connected to the connecting rod via the magnetically-matched winding roller. The steel wire rope on the magnetically-matched winding roller is in a pulling state, and the synchronous driving motor drives the winding roller to perform the winding operation.

[0011] Preferably, the winding roller is located at both ends of the connecting box, and a synchronous control module for controlling the winding roller is provided on the connecting box. A synchronous controller is provided at the center of the synchronous control module, and a driving motor is provided at the center of the winding roller. The driver synchronous controller controls the synchronous control module for synchronous control so as to keep the lifting beam in a balanced state, which greatly improves the overall smooth rising effect and avoids the impact of shaking on the camera effect.

[0012] Beneficial effects of the utility model:

[0013] 1. Different from the previous method of lifting and lowering the beam along the longitudinal beam, the control motor drives the variable pitch module to drive the lifting beam along the slide groove on the longitudinal beam to adjust the rise and fall, realize automatic speed transmission, and achieve efficient energy conversion, thereby improving the efficiency of mechanical transmission. As the lifting beam rises, the steel wire rope on the winding roller is pulled through magnetic attraction, and the synchronous drive motor drives the winding roller to reel in. The driver synchronous controller controls the synchronous control module for synchronous control to keep the lifting beam in a balanced state, which greatly improves the overall smooth rising effect and avoids the impact of shaking on the camera effect.

[0014] 2. With each rise of the lifting beam, changes occur on the horizontal bubble ruler. You only need to observe the deflection to make timely adjustments, thereby increasing the rapid deviation correction performance. When local vibration is transmitted, the shock-absorbing plate, protective cover and protective shock-absorbing cover form a triple protection to avoid the influence of conduction. The synchronous light sensor can assist the horizontal camera to capture light in a timely manner, thereby increasing the observation performance. BRIEF DESCRIPTION OF THE DRAWINGS
