Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a multifunctional ruler for elevator detection. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. It also has a step-type, with the treads mounted on crawlers and running continuously, commonly known as an automatic elevator, a fixed lifting device serving specified floors. It has a car that runs between at least two vertical rigid guide rails or with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods.

[0003] After the installation of the elevator is completed, it is necessary to test whether the elevator meets the use standards. At present, the length and other parameters of the elevator are usually measured by a measuring ruler used for elevator testing;

[0004] The existing measuring ruler for elevator inspection has a relatively simple function during use and can only measure the length of the elevator, so it has low versatility. Some multifunctional rulers for elevator inspection are equipped with measuring equipment such as inclinometers on the outside of the measuring ruler, which can not only measure the length of the elevator, but also measure the inclination angle of the elevator. Although this improves the inspection effect, the operation steps of measuring instruments such as inclinometers are relatively cumbersome and the cost is relatively high. Therefore, we propose a multifunctional ruler for elevator inspection. Utility Model Content

Through the coordinated arrangement of the measuring ruler and the protractor, when inspecting the elevator, not only the length of the elevator can be measured, but also the inclination angle of the elevator can be measured. The structure is simple and the cost is reduced, so that the multifunctional ruler for elevator inspection can complete multiple measurement tasks at one time, thereby greatly improving work efficiency and effectively solving the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional ruler for elevator detection, comprising a base and a measuring mechanism;

[0007] Base: A fixed plate is arranged in the middle of the upper end thereof, a limit plate is arranged on the right side of the rear end of the fixed plate, and a mounting rod is rotatably connected to the lower side of the front end of the fixed plate through a bearing;

[0008] Measuring mechanism: It includes a measuring ruler, a guide slide column, an adjustment plate and a mounting groove. The measuring ruler is arranged at the rear end of the mounting rod. The lower end of the measuring ruler contacts the upper end of the limit plate. The interior of the measuring ruler is provided with a mounting groove. The upper side of the interior of the mounting groove is provided with a guide slide column. The left side of the outer arc surface of the guide slide column is slidably connected with an adjustment plate. The adjustment plate is slidably connected with the inner wall of the mounting groove. Through the coordinated arrangement of the measuring ruler and the protractor, when performing elevator inspection work, not only the length of the elevator can be measured, but also the inclination angle of the elevator can be measured. The structure is simple and the cost is reduced, so that the multifunctional ruler for elevator inspection can complete multiple measurement tasks at one time, thereby greatly improving work efficiency.

[0009] Furthermore, the measuring mechanism also includes a telescopic measuring ruler, which is arranged in the middle of the right end of the adjustment plate. The right end of the telescopic measuring ruler is slidably connected to a connecting groove arranged in the middle of the right wall of the installation groove, which can increase the measuring length of the multifunctional ruler for elevator detection.

[0010] Furthermore, the measuring mechanism also includes a spring, which is arranged between the left end of the adjustment plate and the left wall of the installation groove. The spring is sleeved on the outside of the left side of the guide slide column and can drive the telescopic measuring ruler to move and reset.

[0011] Furthermore, it also includes a baffle, which is arranged at the right end of the telescopic measuring ruler and can adjust the position of the telescopic measuring ruler.

[0012] Furthermore, it also includes a protractor and a pointer, wherein the protractor is arranged at the middle part of the front end of the fixing plate, and the pointer is arranged at the front side of the outer arc surface of the mounting rod. The pointer is located at the front side of the protractor and can measure the angle of the elevator.

[0013] Furthermore, it also includes a torsion spring, which is movably sleeved on the rear side of the outer arc surface of the mounting rod, the front end of the torsion spring is fixedly connected to the outer arc surface of the mounting rod, and the rear end of the torsion spring is fixedly connected to the front end of the measuring ruler, which can drive the pointer to rotate and reset.

[0014] Furthermore, it also includes a level ruler, which is arranged on the upper side of the front end of the fixed plate and can improve the accuracy of the multifunctional ruler for elevator detection.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the multifunctional ruler for elevator detection has the following advantages:

[0016] During operation, the length of the elevator is measured by a measuring ruler. When the length of the measuring ruler is not enough, the baffle is pulled to the right, and the baffle drives the telescopic measuring ruler to move to the right. The telescopic measuring ruler drives the adjustment plate to move to the right along the guide slide column, and the spring extends, thereby increasing the measuring length of the multifunctional ruler for elevator inspection. When the measurement is completed, the baffle is released, and the tension generated by the spring expansion and contraction drives the telescopic measuring ruler to move to the left and reset through the adjustment plate, thereby retracting the telescopic measuring ruler into the interior of the measuring ruler, thereby reducing the floor space occupied by the multifunctional ruler for elevator inspection when not in use. When it is necessary to measure the inclination angle of the elevator, the position of the fixed plate is manually adjusted. When the bubble in the level is in the middle , which means that the fixed plate is in a horizontal state, and then the measuring ruler is pushed. The measuring ruler rotates around the mounting rod, the torsion spring is twisted, and the mounting rod drives the pointer to rotate, and finally the measuring ruler is aligned with the front and rear positions of the elevator. At this time, the value indicated by the pointer on the protractor is the inclination angle of the elevator, thereby realizing the measurement and detection of the inclination angle of the elevator. Through the coordinated setting of the measuring ruler and the protractor, when conducting the inspection of the elevator, not only the length of the elevator can be measured, but also the inclination angle of the elevator can be measured. The structure is simple and the cost is reduced, so that the multifunctional ruler for elevator inspection can complete multiple measurement tasks at one time, thereby greatly improving work efficiency.
