[0001] This utility model relates to the field of elevator testing, specifically an elevator car balance testing device. Background Technology

[0002] As an indispensable vertical transportation tool in modern buildings, the safety and stability of elevators directly affect the lives and travel experience of passengers. The balance of the elevator car is one of the key factors affecting the stability of elevator operation. If there is an imbalance in the car, it may cause shaking, abnormal noises, and car tilting during operation. Over time, this will not only accelerate the wear and tear of components such as guide rails and wire ropes, shortening the service life of the elevator, but may also lead to safety hazards.

[0003] Existing elevator car balance testing devices have many shortcomings in leveling: leveling operations mostly rely on manual adjustment, lack convenient auxiliary structures, and operators need to make repeated adjustments to make the testing benchmark approach horizontal, which is not only time-consuming and laborious, but also the leveling accuracy is greatly affected by human experience and is prone to deviation. Moreover, the adjustment method is singular and it is difficult to adapt to different car tilt testing scenarios. When faced with complex working conditions, it cannot achieve precise leveling.

[0004] To address the aforementioned leveling issues, existing technologies are insufficient to meet the high-precision, high-efficiency, and high-stability testing requirements for elevator car balance. Therefore, there is an urgent need for an elevator car balance testing device that features convenient leveling operation, precise adjustment capabilities, stable vibration resistance, and automatic adaptive adjustment.

[0012] Preferably, the end of the adjusting column is spherical, and the mounting plate has a tapered hole adapted to the adjusting screw.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figures 1-5 As shown, the elevator car balance detection device of this utility model includes a mounting base 1, a connecting base 2 extending into the mounting base 1; a connecting component 3 is provided between the mounting base 1 and the connecting base 2; the connecting base 2 is provided with a mounting plate 5; a plurality of connecting springs 4 are provided between the connecting base 2 and the mounting plate 5, the connecting springs 4 being evenly distributed to facilitate the adjustment of the mounting plate 5 to a horizontal position; the connecting base 2 is provided with a leveling component 6 that contacts the mounting plate 5; the leveling component 6 is provided with a self-leveling detection device 7.

[0029] Furthermore, the connecting component 3 includes an insertion block 31 and a connecting screw 32. The connecting seat 2 is provided with an insertion block 31 extending into the mounting seat 1. The mounting seat 1 is threadedly connected with a connecting screw 32 extending into the insertion block 31. The mounting seat 1 is provided with a positioning groove 101. The connecting seat 2 is provided with a magnetic block 202 extending into the positioning groove 101. The edges of the insertion block 31 and the magnetic block 202 are both inclined. The edge of the positioning groove 101 is inclined to match the magnetic block 202.

[0030] The magnetic block 202 is adapted to the inclined edge of the positioning groove 101. During the connection process, it can be pre-positioned by magnetic force to assist in installation alignment. At the same time, it enhances the tightness and stability of the overall connection and reduces the risk of loosening of the device during elevator operation vibration. Then, through the cooperation of the insertion block 31 and the connecting screw 32, the mounting base 1 and the connecting base 2 can be quickly positioned and firmly connected. The inclined edge design makes it easy for the insertion block 31 to be accurately embedded into the mounting base 1, improving assembly efficiency.

[0031] Furthermore, the leveling assembly 6 includes an adjusting column 61 and an adjusting screw 62. The connecting seat 2 is slidably connected to the adjusting column 61, the other end of which extends into the interior of the mounting plate 5. The connecting seat 2 is rotatably connected to the adjusting screw 62, which is threadedly connected to the adjusting column 61 and extends to the other side of the mounting plate 5. The end of the adjusting column 61 is spherical. The mounting plate 5 has a tapered hole that is adapted to the adjusting screw 62.

[0032] The threaded engagement between the adjusting column 61 and the adjusting screw 62 allows for precise control of the extension and retraction of the adjusting column 61 by rotating the adjusting screw 62, enabling fine-angle adjustments to the mounting plate 5 and ensuring that the level detector 73 is in a horizontal reference state. The spherical design at the end of the adjusting column 61 and the tapered hole design of the mounting plate 5 make the adjustment process more flexible and smooth, reducing frictional resistance between components, making it easier for operators to complete the leveling operation, and improving the leveling accuracy and efficiency.

[0033] Furthermore, the self-leveling detection device 7 includes a spherical shell 71, a movable component 72, a level detector 73, a battery counterweight 74, and a positioning electric push rod 75. The mounting plate 5 is provided with the spherical shell 71, the spherical shell 71 is provided with the movable component 72, the level detector 73 is provided below the movable component 72, the battery counterweight 74 is provided below the level detector 73, and the movable component 72 is provided with a positioning electric push rod 75 adapted to the spherical shell 71. The movable component 72 includes an outer ring 721 and a movable plate 722. The outer ring 721 is movably connected to the spherical shell 71, and the movable plate 722 is movably connected inside the outer ring 721. The level detector 73 is provided at the bottom of the movable plate 722, and the positioning electric push rod 75 is provided at the top of the movable plate 722. The movable connection between the outer ring 721 and the movable plate 722 is arranged in a vertical direction. The output end of the positioning electric push rod 75 is provided with a rubber pad adapted to the inner wall of the spherical shell 71.

[0034] The outer ring 721 of the movable component 72 is movably connected to the spherical shell 71, and the movable plate 722 is movably connected to the outer ring 721 in the vertical direction. This structural design allows the movable plate 722 to rotate flexibly in multiple directions. The battery counterweight 74 under the movable plate 722 will pull the movable plate 722 under the action of gravity, causing the level detector 73 to always tend to maintain a horizontal state. During this process, the level detector 73 can sense whether it is horizontal in real time and feed back the signal. With the positioning electric push rod 75 tightly fitting against the inner wall of the spherical shell 71, the level detector 73 is fixed, thus achieving initial leveling.

[0035] The working principle of the elevator car balance detection device of this utility model is as follows: the device is fixed to the detection position of the elevator car by the mounting base 1, and the connecting base 2 can be connected to the mounting base 1, so that the magnetic block 202 is attracted and positioned by the inclined edge of the positioning groove 101, thus achieving preliminary positioning. The insertion block 31 is inserted into the mounting base 1, and the threaded locking of the connecting screw 32 forms a mechanical fixation, which doubles the tightness and stability of the connection.

[0036] Thus, the battery counterweight 74 below the movable plate 722 pulls the movable plate 722 under the action of gravity, causing the level detector 73 to always tend to maintain a horizontal state. During this process, the level detector 73 can sense whether it is horizontal in real time and feed back the signal. In conjunction with the positioning electric push rod 75, it fits tightly against the inner wall of the spherical shell 71, thereby fixing the level detector 73 and achieving initial leveling.

[0037] The connecting seat 2 is connected to the mounting plate 5 through the connecting springs 4 distributed in a rectangular array. The spring structure can buffer the vibration interference during elevator operation and provide a relatively stable support foundation for the mounting plate 5. When the initial adjustment is not precise enough, the adjusting screw 62 can be rotated to make it engage with the thread of the adjusting column 61 to drive the adjusting column 61 to extend and retract. The spherical end rotates flexibly in the conical hole, realizing multi-angle fine adjustment of the mounting plate 5 to ensure that it is in a horizontal state.

[0038] When the elevator car is running, the level detector 73 monitors the level status of the mounting plate 5 in real time. Since the mounting plate 5 has been calibrated by the leveling components and is protected by spring buffer, its level changes can accurately reflect the changes in the balance of the car, thereby achieving accurate detection and monitoring of the balance status of the elevator car.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
