Description

Technical Field

[0001] This utility model relates to the field of motor synchronization testing technology, and in particular to a flexible stage machinery motor synchronization testing device. Background Technology

[0002] Stage machinery refers to specialized mechanical systems used in stage performances. It serves as a visual medium, supporting element, or even a character in the performance, assisting in the artistic presentation of stage creativity. It is a tool and medium for interpreting culture. Stage machinery can be found both indoors and outdoors, inside and outside stage performance areas, and is widely used in conference venues, theaters, television studios, tourist entertainment venues, mobile performances, and themed exhibitions.

[0003] Stage machinery equipment, such as electric hoists, lighting hoists, single-point hoists, and lifting platforms, primarily uses electric motors as their power source. Since multiple sets of this stage equipment are often used and require synchronized operation, specialized testing equipment is typically needed to conduct synchronized tests on the electric motors in a laboratory to test and verify the synchronized control performance of the electrical control system's hardware and software.

[0004] Existing motor synchronization testing devices have the following technical problems:

[0005] 1. The base is mostly welded from profiles such as channel steel. The motor bracket is fixed with bolts and cannot be moved or adjusted. Moreover, this type of base has poor precision, and the motor already has errors after installation, which will affect the accuracy of the test results.

[0006] 2. Lack of versatility: Each type of motor requires a dedicated testing device. Due to the wide variety of stage equipment with varying parameters, different types of drive motors are needed. Motors of different models differ in size, and existing testing devices are often designed for a single type of motor, making them incompatible with different models.

[0007] 3. Significant noise and vibration during testing. The existing motor synchronization testing device is a rigid structure without shock absorption devices, which generates significant vibration and noise during testing. Utility Model Content

[0008] This invention provides a flexible stage machinery motor synchronous testing device, which solves the shortcomings of the prior art, such as low accuracy of test results, incompatibility between different motor models, and large vibration and noise during testing.

[0009] This utility model provides the following technical solution:

[0010] A flexible stage machinery motor synchronous testing device includes a base, on which two opposing motor brackets are fixed. The motor brackets are slidably mounted on the base. The motor brackets have the same structure and each has a circular opening at the top. An annular motor transition plate is installed in the circular opening, and a motor is installed on the motor transition plate. The output shaft of the motor passes through the circular opening.

[0011] In one possible implementation, the base is formed by four aluminum alloy guide rails forming a rectangular frame, and corner brackets are provided at the right angles of adjacent aluminum alloy guide rails. The corner brackets are fixedly connected to the aluminum alloy guide rails by first T-bolts.

[0012] In one possible implementation, a T-shaped groove is formed on the upper side of the aluminum alloy guide rail, and a second T-bolt is fixed to the bottom of the motor bracket, with the bolt head of the second T-bolt extending into the groove.

[0013] In one possible implementation, a rubber shock-absorbing pad is also fixed to the bottom of the motor bracket, and the rubber shock-absorbing pad is fixedly installed by a second T-bolt.

[0014] In one possible implementation, the motor transition plate is provided with a set of motor bracket mounting holes and a set of motor mounting holes, wherein the motor bracket mounting holes are adapted to the mounting holes on the motor bracket, and the motor mounting holes are adapted to the mounting holes on the motor.

[0015] In one possible implementation, the motor bracket comprises a horizontally arranged base plate and a vertically arranged upright plate, and a reinforcing plate is installed between the upright plate and the base plate, the reinforcing plate being located on both sides of the base plate and the upright plate.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] This application is used for laboratory testing of stage machinery motor synchronization. The base is fixed with aluminum alloy guide rails, which improves precision and the accuracy of test results. The bracket can be moved on the base to adjust its position and spacing, making it suitable for synchronous testing of motors of various specifications and highly versatile.

[0018] This application is used for laboratory testing of stage machinery motor synchronization. A rubber damping pad is added between the base and the motor bracket. The rubber damping pad can reduce the vibration and noise generated during the test.

[0019] This application is used for synchronous testing of stage machinery motors. The motor is fixed to the motor bracket by bolts through a transition plate. The size of the motor transition plate can be adjusted to adapt to the testing requirements of different motor models. The universal design reduces the processing and production cost and enhances interchangeability. Attached Figure Description

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figure 2 As shown, this application provides a flexible stage machinery motor synchronization testing device, including a base 4, on which two opposing motor brackets 5 are fixed. The motor brackets 5 are slidably mounted on the base 4. The motor brackets 5 have the same structure, each with a circular opening at the top. An annular motor transition plate 7 is installed in the circular opening, and a motor 6 is mounted on the motor transition plate 7. The output shaft of the motor 6 passes through the circular opening. By mounting the motor 6 on the motor transition plate 7 and then mounting the motor 6 transition plate on the motor bracket 5, the motor 6 can be ensured to be mounted on the motor bracket 5. When it is necessary to test the synchronization of different types of motors 6, only the corresponding motor transition plate 7 needs to be replaced. The entire testing device does not need to be replaced, which can significantly improve versatility. After being mounted on the motor brackets 5, the distance between the two motor brackets 5 can be adjusted by adjusting the relative position of the motor brackets 5, that is, by driving one motor bracket 5 to slide along the base 4 toward the other motor bracket 5. This allows for the adjustment of the distance between the two motors 6, thus making it suitable for testing more specifications of motors 6. After adjustment, the motor brackets 5 and the base 4 are fixed by tightening the second T-bolt 10.

[0027] Furthermore, such as Figure 1As shown, the base 4 is formed by four aluminum alloy guide rails 1 forming a rectangular frame, and corner brackets 2 are set at the right angles of adjacent aluminum alloy guide rails 1. The corner brackets 2 are fixedly connected to the aluminum alloy guide rails 1 by the first T-bolts 3. By using aluminum alloy guide rails 1, the precision can be improved and the accuracy of the test results can be improved.

[0028] Specifically, such as Figure 1 As shown, the base 4 is provided with four aluminum alloy guide rails 1, including two long guide rails and two short guide rails, so that the four aluminum alloy guide rails 1 form a rectangular frame. The aluminum alloy guide rails 1 are conventional aluminum alloy profiles, and the aluminum alloy profiles have grooves on their four sides.

[0029] Furthermore, such as Figure 1 As shown, a T-shaped groove is formed on the upper side of the aluminum alloy guide rail 1. A second T-bolt 10 is fixed at the bottom of the motor bracket 5. The bolt head of the second T-bolt 10 extends into the groove so that the position of the motor bracket 5 can be adjusted along the direction of the T-shaped groove, thereby accommodating more specifications of motors 6. After the motor 6 is fixedly installed on the motor bracket 5, it can still be finely adjusted to improve the accuracy of the detection.

[0030] Specifically, such as Figure 2 As shown, the second T-bolt 10 extends into the long side groove of the aluminum alloy guide rail 1, thereby providing a wider adjustment range. The height of the two short side aluminum alloy guide rails 1 is lower than that of the two long side aluminum alloy guide rails 1. The two ends of the two short side aluminum alloy guide rails 1 are fixedly connected to the inner side of the two long side aluminum alloy guide rails 1, so that when adjusting the position of the motor bracket 5, the limit distance can be pressed against the two short side aluminum alloy guide rails 1, thereby improving the adjustment range.

[0031] Furthermore, such as Figure 2 As shown, a rubber damping pad 8 is also fixed at the bottom of the motor bracket 5. The rubber damping pad 8 is fixedly installed by the second T-bolt 10. When external vibration acts on the rubber damping pad 8, the rubber material can absorb and disperse vibration energy through the conformational change of the molecular chain, thereby effectively reducing the transmission of vibration.

[0032] Specifically, the rubber shock absorber 8 is designed as a long strip, the length of which is adapted to the length of the bottom of the motor bracket 5, and the width of which is adapted to the width of the aluminum alloy guide rail 1, so that the rubber shock absorber 8 can fully absorb the vibration of the motor bracket 5 guiding the aluminum alloy guide rail 1.

[0033] Furthermore, such as Figure 2As shown, the motor transition plate 7 is provided with a set of motor bracket 5 mounting holes and a set of motor 6 mounting holes. The motor bracket 5 mounting holes are adapted to the mounting holes on the motor bracket 5, and the motor 6 mounting holes are adapted to the mounting holes on the motor 6. Therefore, by simply replacing different motor transition plates 7, the position of the motor bracket 5 mounting holes on the outer ring of different motor transition plates 7 remains unchanged, while the motor 6 mounting holes on the inner ring are adapted to different specifications of motors 6. This allows for the use of different specifications of motors 6 simply by replacing different motor transition plates 7, thus enabling convenient installation and fixing of motors 6 of different specifications.

[0034] Specifically, such as Figure 2 As shown, the motor transition plate 7 is annular. The circular hole in the middle of the motor transition plate 7 allows the output shaft of the motor 6 to pass through. There are four motor bracket 5 mounting holes on the outer edge of the motor transition plate 7 and four motor 6 mounting holes on the inner edge of the motor transition plate 7. The mounting holes of the motor bracket 5 and the mounting holes of the motor 6 are all on the annular path with the center, so that the output shaft of the motor 6 installed and fixed on the motor bracket 5 can be accurately aligned. The motor transition plate 7 is fixed to the motor bracket 5 by bolt group 9, and the motor 6 is fixed to the motor transition plate 7 by bolt group 9.

[0035] Furthermore, such as Figure 2-3 As shown, the motor bracket 5 consists of a horizontally arranged base plate and a vertically arranged upright plate, and a reinforcing plate is installed between the upright plate and the base plate. The reinforcing plate is located on both sides of the base plate and the upright plate. By setting the reinforcing plate, the strength of the upright plate and the base plate can be improved.

[0036] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
