Description

Technical Field

[0001] This utility model relates to a testing instrument, and more particularly to a testing instrument for measuring the descent speed of a motorcycle hoist. Background Technology

[0002] A motorcycle hoist descent speed tester is a device specifically designed to measure the speed of a motorcycle hoist during its descent. This tester is crucial for ensuring the safety of motorcycle hoists because it helps determine whether the hoist is operating smoothly at the expected speed, avoiding safety hazards caused by excessively fast or unstable descent speeds.

[0003] Existing methods for measuring the descent speed of motorcycle hoists mostly rely on manual operation, where a worker holds a speed measuring instrument and measures the speed of the descending hoist. However, due to human factors (such as the difficulty in ensuring the instrument remains absolutely stable throughout the process), all such methods are often accompanied by insufficient accuracy and inconvenience. Utility Model Content

[0004] In order to overcome the shortcomings of existing methods for measuring the descent speed of motorcycle hoists, which mostly rely on manual operation and have insufficient accuracy and inconvenience, the purpose of this utility model is to provide a testing instrument for measuring the descent speed of motorcycle hoists.

[0005] The technical solution of this utility model is as follows: a testing instrument for measuring the descent speed of a motorcycle hoist, comprising a sliding rod, a support plate, a digital timer, a controller, a rotating frame, a user interface, an upper photoelectric switch, a lower photoelectric switch, and a laser rangefinder. The sliding rod is slidably connected to two support plates from top to bottom. A digital timer is located at the top center of the upper support plate, an upper photoelectric switch is located at the rear center of the upper support plate, and a lower photoelectric switch is located at the rear center of the lower support plate. A square hole is opened on the left side of the upper support plate, and a laser rangefinder is installed inside the square hole. A rotating frame is rotatably connected to the front right side of the upper support plate. The end of the rotating frame away from the support plate is connected to the controller. The controller has a user interface. The digital timer, user interface, upper photoelectric switch, lower photoelectric switch, and laser rangefinder are all electrically connected to the controller.

[0006] As a further preferred option, a limit groove is provided at the front end of the sliding rod.

[0007] As a further preferred embodiment, symmetrical inclined surfaces are provided on the left and right sides of the top of the sliding rod. The inclined surface on the left gradually slopes from the left end of the sliding rod to the top of the sliding rod, and the inclined surface on the right gradually slopes from the right end of the sliding rod to the top of the sliding rod.

[0008] As a further preferred embodiment, it also includes a screw and a base, with the internal thread of the sliding rod connected to the screw and the bottom end of the screw connected to the base.

[0009] As a further preferred option, the bottom of the base has friction grooves spaced apart.

[0010] As a further preferred option, bolts are also included. Each of the front left sides of the support plate is provided with a screw hole, and each screw hole is threaded with a bolt. The rear end face of each bolt abuts against the limiting groove.

[0011] The beneficial effects of this utility model are: 1. The position of the lifting plate is detected by the upper photoelectric switch and the lower photoelectric switch, the digital timer is used to record the time of the lifting plate sliding, and the laser rangefinder measures the distance between the two support plates. This eliminates the need for manual measurement of the sliding speed of the motorcycle lifting machine, reduces the factor of human intervention, ensures the consistency and repeatability of the test, and calculates the sliding speed accordingly, thereby improving the accuracy of the measurement results.

[0012] 2. The rotating frame design allows users to adjust the angle of the controller as needed, making the user interface easier to view and operate. The bolt-fixed support plate simplifies the installation and debugging process and improves work efficiency. Attached Figure Description

Detailed Implementation

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] A testing instrument for measuring the descent speed of a motorcycle hoist, such as Figures 1-3 As shown, the device includes a sliding rod 1, a support plate 4, bolts 5, a digital timer 6, a controller 7, a rotating frame 701, a user interface 702, an upper photoelectric switch 8, a lower photoelectric switch 801, and a laser rangefinder 9. A limit groove 101 is formed at the front end of the sliding rod 1. Sloping surfaces 102 are symmetrically arranged on the left and right sides of the top of the sliding rod 1. The left slope 102 gradually slopes from the left end of the sliding rod 1 towards the top, and the right slope 102 gradually slopes from the right end of the sliding rod 1 towards the top. With the end tilted, initially, the support plate 4 needs to be installed on the sliding rod 1. The presence of the inclined surfaces 102 on both sides facilitates the installation of the support plate 4 on the sliding rod 1. The sliding rod 1 is slidably connected to two support plates 4 from top to bottom. Each support plate 4 has a screw hole 401 on the left side of its front end, and a bolt 5 is threaded into each screw hole 401. The rear end face of each bolt 5 abuts against the limiting groove 101. The rear end face of each bolt 5 abuts against the limiting groove 101, which will prevent the support plate 4 from being installed on the sliding rod 1. The upper support plate 4 has a digital timer 6 at the top center, which records the time of the motorcycle hoist's descent. The upper support plate 4 has an upper photoelectric switch 8 at the rear center, and the lower support plate 4 has a lower photoelectric switch 801 at the rear center. The upper and lower photoelectric switches 801 are used to detect the position of the hoist. The upper support plate 4 has a square hole 402 on its left side, and a laser rangefinder 9 is installed inside the square hole 402. The laser rangefinder 9 is used to measure the distance between the two support plates 4. The upper support plate 4 has a rotating frame 701 rotatably connected to the front right side. The end of the rotating frame 701 away from the support plate 4 is connected to a controller 7. The controller 7 has a user interface 702. The rotating frame 701 allows the controller 7 to adjust the angle as needed so that people can operate the user interface 702 more conveniently. The digital timer 6, the user interface 702, the upper photoelectric switch 8, the lower photoelectric switch 801, and the laser rangefinder 9 are all electrically connected to the controller 7.

[0020] like Figures 1-4 As shown, it also includes a screw 2 and a base 3. The internal thread of the sliding rod 1 is connected to the screw 2. By rotating the screw 2, the height of the sliding rod 1 can be adjusted, thereby adjusting the height of the tester. The bottom end of the screw 2 is connected to the base 3. The bottom end of the base 3 is spaced apart with friction grooves 301. The friction grooves 301 increase the friction between the base 3 and the ground, which can prevent the tester from sliding.

[0021] Place this testing instrument next to the motorcycle lift, start the motorcycle lift, and raise the lift plate (i.e., the motorcycle placement plate) to the test height. Turn off the motorcycle lift, loosen the bolt 5 on the left side of the upper support plate 4 (i.e., the rear end of bolt 5 no longer abuts against the limiting groove 101), move the support plate 4 so that the upper photoelectric switch 8 is aligned with the lift plate (i.e., the upper photoelectric switch 8 can detect the lift plate), then tighten the bolt 5 (i.e., the rear end of bolt 5 abuts against the limiting groove 101 again), fix the upper support plate 4, loosen the bolt 5 on the left side of the lower support plate 4 so that the lower photoelectric switch 801 is aligned with the initial position of the lift plate (i.e., the end point of the lift plate's descent), then tighten the bolt 5 to fix the lower support plate 4, start the laser rangefinder 9, the laser rangefinder 9 measures the distance between the upper and lower support plates 4, and then transmits it to the control... Controller 7 restarts the motorcycle lift, causing the lifting plate on the motorcycle lift to slide down. When the lifting plate moves downward and the upper photoelectric switch 8 can no longer detect the lifting plate, the upper photoelectric switch 8 transmits a signal to controller 7. Controller 7 controls digital timer 6 to start timing. When the lifting plate slides to the end point and the lower photoelectric switch 801 detects the lifting plate, the lower photoelectric switch 801 transmits a signal to controller 7. Controller 7 controls digital timer 6 to stop timing. Digital timer 6 transmits the measured time to controller 7. Controller 7 uses the physical formula (V=S / t) to calculate the average speed of the lifting machine's descent (S is the distance between the upper and lower support plates 4, t is the time measured by digital timer 6, and V is the descent speed of the lifting machine). The calculated speed value will be displayed on the user interface 702 for the operator to view.

[0022] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
