Description

Technical Field

[0001] The invention relates to the technical field of motor detection, and in particular to a fault detection device for a treadmill motor. Background Art

[0002] A treadmill is a high-end piece of equipment used in gyms and homes. It uses a motor to drive the running belt, allowing people to passively run or walk at different speeds. It is mainly composed of structures such as a motor, transmission rollers, a transmission belt, a running belt and a frame. The motor on a treadmill can be damaged due to various reasons during long-term use. Therefore, a fault inspection device is needed to check which part of the motor is damaged for precise repair.

[0003] The existing motor fault detection device mainly installs multiple sensors on the motor, detects various values ​​of the motor, and compares them with normal motor values ​​to achieve motor fault detection. However, various faults may occur in the motor during use, and many of them will be directly reflected in the rotation speed. In addition, during the use of the treadmill, since people actually contact the running belt at intervals when running on the treadmill, the load on the motor is also intermittent, so the current and voltage fluctuate differently during running. When detecting some faults that occur during use of the treadmill, the inspection personnel need to use it on the treadmill to measure the relevant values. However, the treadmill is in a faulty state at this time. Once the inspection personnel simulate the use of the inspection values ​​and a fault occurs, it will not only cause certain safety hazards to the inspection personnel, but also fail to accurately and efficiently determine the motor fault problem.

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-8 The fault inspection device for a treadmill motor shown in the figure comprises a base 1, a transmission seat 2 is provided on the top of the base 1, a rotating rod 3 is rotatably connected to the side wall of the transmission seat 2, and one end of the rotating rod 3 is fixedly connected to a pulley 4 connected to the output end of the treadmill motor through a belt, the outer wall of the rotating rod 3 and the two sides of the transmission seat 2 are fixedly connected with push rods 5, the two sides of the outer wall of the transmission seat 2 are respectively rotatably connected with an upper winding roller 6 and a lower winding roller 7, the inner top end of the upper winding roller 6 and the inner bottom end of the lower winding roller 7 are fixedly connected with a fixing plate 8, the side walls of the fixing plate 8 are all penetrated by a limiting rod 9 that is slidably connected, the limiting rod 9 is extended from the fixed plate 8 on the side away from the limiting rod 9, and the push rods 5 are all arranged at a position corresponding to the extended part of the limiting rod 9;

[0030] The outer wall of the limit rod 9 is fixedly connected with a fixing ring 10, and an upper spring 11 is fixedly connected between the side wall of the fixing ring 10 and the side wall of the fixing plate 8. An inwardly recessed upper groove 12 is provided on the outer wall of the transmission seat 2 and at the bottom near one end of the upper winding roller 6, and an inwardly recessed lower groove 13 is provided on the outer wall of the transmission seat 2 and at the top near one end of the lower winding roller 7. The upper groove 12 and the lower groove 13 are both arranged on the rotation track of the limit rod 9, and the inner side of the upper groove 12 and the inner side of the lower groove 13 are both inclined, and the side close to the limit rod 9 is arranged as a smooth arc surface. By inclinedly arranging the side walls of the upper groove 12 and the lower groove 13 and arranging the end of the limit rod 9 as a smooth arc surface, it is convenient for the limit rod 9 to quickly slide out of the inner sides of the upper groove 12 and the lower groove 13, thereby improving the smoothness of the device during operation. A pair of sliding frames 14 are fixedly connected to the top of the base 1, and the sliding position of the sliding block 15 is adjusted by the sliding frame 14 The position is limited, the inner side of the sliding frame 14 is slidably connected with a sliding block 15, and the outer walls of the upper winding roller 6 and the lower winding roller 7 are wound with a pull rope 16, one end of the pull rope 16 is fixedly connected to the outer walls of the upper winding roller 6 and the lower winding roller 7 respectively, and the other end of the pull rope 16 is fixedly connected to the side wall of the sliding block 15, and a return spring 17 is fixedly connected between the side wall of the sliding block 15 and the inner side of the sliding frame 14, and the top of the sliding block 15 is fixedly connected with a positioning rod 18, and the position of the counterweight ring 19 can be limited by the positioning rod 18 to improve the stability during the inspection process, and a counterweight ring 19 is provided on the top of the sliding block 15 and on the outside of the positioning rod 18, and the counterweight ring 19 can increase the resistance of the sliding block 15 when sliding, and according to the number of counterweight rings 19 placed, the load condition during the motor test can be adjusted to meet the motor values ​​in different usage conditions and increase the inspection range of the device;

[0031] When inspecting the motor on the treadmill, first open the inspection panel on the treadmill, then open the shielding cover 22, and at the same time, make the side wall of the base 1 butt against the side wall of the treadmill to avoid a gap that affects the transmission of the subsequent belt, thereby affecting the normal inspection of the device, then take out the belt between the motor drive roller and the running belt, install the belt between the motor drive roller and the pulley 4, and install the sensor at the same time, then you can control the motor on the treadmill to start, and drive the pulley 4 to rotate at the same time under the transmission of the belt, and then drive the rotating rod 3 to rotate, and then drive the push rod 5 to rotate, because the upper winding roller 6 and the lower winding roller 7 have different positions of the limit rod 9 on the inner side, so the push rod 5 will first push the limit rod 9 on the inner side of the upper winding roller 6, and then drive the upper winding roller 6 to rotate, and then the pull rope 16 on the upper winding roller 6 is wound;

[0032] When the treadmill 14 is in operation, the cam 16 is retracted to the stopper 16, and the cam 16 is retracted to the stopper 16.

[0033] In order to facilitate carrying the inspection device for inspection outside, a top frame 20 is fixedly connected to the top of the base 1, and a movable groove 21 is opened at the top of the top frame 20 and at a position corresponding to the sliding frame 14. The movable groove 21 avoids affecting the increase or decrease of the counterweight ring 19 during inspection. A shielding cover 22 is hingedly connected to the side wall of the top frame 20 and located above the transmission seat 2, and the bottom of the shielding cover 22 is inserted into the top of the base 1, so that the position of the shielding cover 22 can be fixed to prevent the portable shielding cover 22 from shaking at will. A lifting ring 23 is rotatably connected to the outer side of the top frame 20. The lifting ring 23 is convenient for inspectors to lift the top frame 20 and the base 1 to carry them outside. At the same time, the lifting ring 23 can rotate to avoid hindering the opening of the shielding cover 22.

[0034] In order to facilitate carrying the counterweight ring 19, a plurality of placement grooves 24 for placing the counterweight ring 19 are provided on the top of the top frame 20, and a circular ring 25 adapted to the counterweight ring 19 is fixedly connected to the bottom of the plurality of placement grooves 24, and three elastic sheets 26 are fixedly connected to the top of the circular ring 25, and a right-angle block 27 is fixedly connected to the far side of the three elastic sheets 26;

[0035] By setting the elastic sheet 26, the circular ring 25 and the right-angle block 27, the position of the counterweight ring 19 in the placement groove 24 can be fixed. When the counterweight ring 19 needs to be taken out, the right-angle blocks 27 on the side walls of the three elastic sheets 26 can be squeezed toward the middle to cause the elastic sheet 26 to be elastically deformed, and then the right-angle blocks 27 are pushed out above the counterweight ring 19 and moved above the hole of the counterweight ring 19, thereby releasing the position fixation of the counterweight ring 19, and then the counterweight ring 19 can be pulled out for use. During installation, the holes on the counterweight ring 19 are directly aligned with the three right-angle blocks 27, and then the counterweight ring 19 is pressed downward to squeeze the inclined surfaces of the right-angle blocks 27 to deform the elastic sheet 26, and then the counterweight ring 19 can be inserted into the circular ring 25, and then the squeezing of the right-angle blocks 27 is released, and the elastic force of the elastic sheet 26 itself drives the right-angle blocks 27 to reset and get stuck on the top of the counterweight ring 19, thereby limiting the position of the counterweight ring 19, making it convenient to carry and inspect outside, and improving the convenience of the device.

[0036] In order to adjust the position of the pulley 4 for treadmills of different models, an adjusting slot 28 is provided on the top of the base 1, an adjusting block 29 is slidably connected to the inner side of the adjusting slot 28, and the transmission seat 2 is fixedly connected to the top of the adjusting block 29, a through slot 30 is provided at the bottom of the adjusting block 29, a rack 31 is fixedly connected to the bottom of the adjusting slot 28 and at a position corresponding to the through slot 30, a gear 32 meshing with the rack 31 is rotatably connected to the bottom of the through slot 30, and a turntable 33 is fixedly connected to the top of the gear 32 through the top of the adjusting block 29;

[0037] A bottom rod 34 is slidably connected to the top of the adjusting block 29, a tooth plate 35 meshing with the gear 32 is fixedly connected to the bottom of the bottom rod 34, and a gap is left between the bottom of the tooth plate 35 and the bottom end of the adjusting slot 28, a top plate 36 is fixedly connected to the top of the bottom rod 34, and a lower spring 37 is fixedly connected between the bottom of the top plate 36 and the top of the adjusting block 29;

[0038] When the position of the pulley 4 needs to be adjusted according to different models of treadmills, the top plate 36 is first pressed downward to drive the bottom rod 34 to slide downward, and the lower spring 37 is compressed, thereby driving the toothed plate 35 to slide downward and out of the meshing position with the gear 32, thereby releasing the rotation restriction of the gear 32, and then the turntable 33 can be turned to drive the gear 32 to rotate. Since the rack 31 and the gear 32 are meshed with each other, and the rack 31 is fixed to the inner side of the adjusting groove 28, the adjusting block 29 will slide inside the adjusting groove 28 under the action of rotation. The top plate 36 is then released and pushed upward by the elastic force of the lower spring 37, and the bottom rod 34 and the toothed plate 35 are simultaneously driven to move upward, so that the toothed plate 35 slides to the meshing position with the gear 32, thereby limiting the rotation position of the gear 32, and then fixing the position of the transmission seat 2 and the pulley 4, thereby ensuring the stability in the subsequent transmission process;

[0039] At the same time, through the setting of the above structure, the belt can be used when it is installed on the pulley 4 on the treadmill, and the belt can be quickly tightened without the need for the inspection personnel to force the belt to install it, which saves time and effort and improves the convenience of the device.

[0040] In order to avoid the phenomenon that a gap appears between the counterweight ring 19 and the sliding block 15 when the position of the transmission seat 2 is adjusted, an annular groove 38 is provided on the side close to the upper winding roller 6 and the lower winding roller 7, and a spiral spring 39 is provided inside the annular groove 38, one end of the spiral spring 39 is fixedly connected to the inside of the annular groove 38, and the other end of the spiral spring 39 is fixedly connected to the outer wall of the transmission seat 2;

[0041] Through the setting of the volute spring 39 and the annular groove 38, when the position of the transmission seat 2 is adjusted toward the side of the sliding block 15, since the position of the sliding block 15 is fixed, the pull rope 16 will be in a relaxed state, and the volute spring 39 will be in a contracted state at this time. Therefore, when the transmission seat 2 moves toward the side of the sliding block 15, the pull rope 16 loses its tension, so the volute spring 39 will drive the upper winding roller 6 and the lower winding roller 7 to rotate to wind up the excess part of the pull rope 16, ensuring that the pull rope 16 is always in a taut state. When the push rod 5 is pushed, the motor load can be checked, and the volute spring 39 will contract when the push rod 5 pushes the upper winding roller 6 and the lower winding roller 7 to rotate, and will not hinder the normal operation of the device.

[0042] The basic principles, main features and advantages of the present invention are shown and described above.

[0043] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
