[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0033] Reference below Figures 1-5 The present invention describes a gear rotation speed measuring device and a detachable ropeway according to an embodiment of the present invention.

[0034] like Figures 1-5 As shown, the gear rotation speed measuring device according to the embodiment of the utility model comprises a frame assembly 1 , a rotating shaft 2 , a measuring gear 3 and a rotation speed measuring device 5 .

[0035] The rotating shaft 2 is connected to the frame assembly 1 and can rotate relative to the frame assembly 1 about the axis of the rotating shaft 2. The measuring gear 3 is connected to one end of the rotating shaft 2 to drive the rotation of the rotating shaft 2. The measuring gear 3 is used for meshing and driving connection with the gear 4 to be measured. The revolution counter 5 is arranged on the frame assembly 1 and is connected to the other end of the rotating shaft 2.

[0036] Specifically, as Figures 1-5 shown, the rotating shaft 2 extends in the vertical direction. The rotating shaft 2 is arranged on the frame assembly 1 and can rotate relative to the frame assembly 1 about the vertical direction. The bottom of the rotating shaft 2 is connected to the measuring gear 3. The measuring gear 3 is horizontally arranged to drive the synchronous rotation of the rotating shaft 2 and the measuring gear 3. The top of the rotating shaft 2 is connected to the revolution counter 5. The revolution counter 5 is arranged on the frame assembly 1. When the rotating shaft 2 and the measuring gear 3 rotate synchronously, the revolution counter 5 can obtain the revolutions of the rotating shaft 2 and the measuring gear 3.

[0037] When the gear revolution measuring device is measuring, the measuring gear 3 is in meshing and driving connection with the gear 4 to be measured. When the gear 4 to be measured rotates, it drives the measuring gear 3 to rotate, and is counted by the revolution counter 5. The revolutions of the rotating shaft 2 and the measuring gear 3 obtained by the revolution counter 5 can be deduced to obtain the revolutions of the gear 4 to be measured.

[0038] The gear revolution measuring device of the embodiment of the present utility model is provided with a measuring gear. The measuring gear is connected to the revolution counter through a rotating shaft. When measuring, the measuring gear is in meshing and driving connection with the gear to be measured to ensure stable connection between the measuring gear and the gear to be measured. By obtaining the revolutions of the measuring gear and the rotating shaft through the revolution counter, it can be converted into the revolutions of the gear to be measured. Therefore, the gear revolution measuring device of the embodiment of the present utility model can avoid situations such as missed reading and misreading, and has high measuring accuracy and accuracy. At the same time, the gear revolution measuring device of the embodiment of the present utility model has a compact structure, is convenient for installation and maintenance, and has strong applicability.

[0039] In some embodiments, the measuring gear 3 is a nylon gear to reduce the impact and swing amplitude of the gear 4 to be measured when it rotates, avoid the vibration of the gear 4 to be measured from affecting the accuracy of the result obtained by the revolution counter 5, and also avoid damage to the connected measuring gear 3, rotating shaft 2 and revolution counter 5. In addition, it can also reduce the noise generated during the rotation of the gear 4 to be measured and the measuring gear 3, and has a shock absorption effect.

[0040] In some embodiments, the revolution counter 5 is an encoder to facilitate accurately obtaining the revolutions of the rotating shaft 2 and the measuring gear 3.

[0041] In some embodiments, the gear rotation speed measuring device of the embodiment of the present utility model further includes an end shaft baffle 6, which is detachably arranged on the axial end face of the measuring gear 3. An installation groove is provided on the outer peripheral surface of the rotating shaft 2. Part of the end shaft baffle 6 is embedded in the installation groove and abuts against the bottom surface of the installation groove.

[0042] As Figure 2 and Figure 4 shown, an end shaft baffle 6 is provided on the bottom surface of the measuring gear 3. Preferably, the end shaft baffle 6 is detachably connected to the measuring gear 3 by bolts. The end shaft baffle 6 is a strip extending in the front-rear direction, and the end shaft baffle 6 is arranged offset from the axis of the measuring gear 3, preferably located on the left side of the axis of the measuring gear 3. The rotating shaft 2 is coaxially arranged with the measuring gear 3. The lower end of the rotating shaft 2 extends downward out of the measuring gear 3, and an installation groove is provided on the outer peripheral surface of the lower end of the rotating shaft 2. The installation groove penetrates through the rotating shaft 2 in the front-rear direction. The middle part of the end shaft baffle 6 is embedded in the installation groove in the rightward direction, and the right end surface of the end shaft baffle 6 abuts against the bottom surface of the installation groove.

[0043] When the gear 4 to be measured drives the measuring gear 3 to rotate, the end shaft baffle 6 rotates synchronously with the measuring gear 3 around the axis of the measuring gear 3, and pushes the rotating shaft 2 to rotate synchronously around the axis of the measuring gear 3 by abutting against the right end surface of the bottom surface of the installation groove, and the connection reliability is relatively high. At the same time, by disassembling the end shaft baffle 6, it is convenient to replace and maintain the measuring gear 3.

[0044] It can be understood that the connection structure between the rotating shaft 2 and the measuring gear 3 is not limited to the structure as Figure 2 shown. In some other embodiments, the rotating shaft 2 and the measuring gear 3 are connected by a key.

[0045] In some embodiments, the gear rotation speed measuring device of the embodiment of the present utility model further includes a coupling 7, and the coupling 7 is connected between the other end of the rotating shaft 2 and the shaft end of the rotation speed measuring device 5.

Preferably, the coupling 7 is a flexible coupling.

[0047] In some embodiments, the gear rotation speed measuring device of the embodiment of the present utility model further includes a bearing 8. The outer ring of the bearing 8 is connected to the frame assembly 1, and the inner ring of the bearing 8 is sleeved on the outer peripheral surface of the rotating shaft 2, so that the rotating shaft 2 can rotate relative to the frame assembly 1 around the axis of the rotating shaft 2.

[0048] As Figure 2 and Figure 5As shown, a bearing 8 is provided on the frame assembly 1, and the outer ring of the bearing 8 is connected to the frame assembly 1. The inner ring of the bearing 8 is sleeved on the outer peripheral surface of the rotating shaft 2, so that the inner ring of the bearing 8 rotates synchronously with the rotating shaft 2, thereby enabling the rotating shaft 2 to rotate relative to the frame assembly 1 about the axis of the rotating shaft 2 and avoiding a large frictional resistance during the transfer process.

[0049] In some embodiments, there are at least two bearings 8, and the at least two bearings 8 are arranged in sequence along the axial direction of the rotating shaft 2.

[0050] As Figure 2 and Figure 5 shown, preferably there are two bearings 8, and the two bearings 8 are arranged in sequence in the vertical direction to support the rotating shaft 2 through the double bearings 8, enabling the rotating shaft 2 to have better centering and stability, which is convenient for the installation and adjustment of the rotating shaft 2.

[0051] Preferably, as Figure 5 shown, the gear revolution measurement device of the embodiment of the present utility model further includes a retaining ring 9 and a bushing 10. Preferably, there are two bushings 10, and the two bushings 10 are arranged at intervals in the vertical direction. The two bearings 8 are arranged at intervals in the vertical direction. The two bushings 10 include a first bushing 10 and a second bushing 10, and the two bearings 8 include a first bearing 8 and a second bearing 8. The first bushing 10 is borne on the upper end surface of the measuring gear 3 and sleeved on the outer peripheral surface of the rotating shaft 2. The inner ring of the first bearing 8 is borne on the upper end surface of the first bushing 10. The second bushing 10 is borne on the top surface of the inner ring of the first bearing 8 and sleeved on the outer peripheral surface of the rotating shaft 2. The inner ring of the second bearing 8 is borne on the upper end surface of the second bushing 10. The retaining ring 9 is connected to the frame assembly 1 or the rotating shaft 2 and sleeved on the outer periphery of the rotating shaft 2, and the retaining ring 9 stops the upper end surface of the second bearing 8, thereby installing the two bearings 8 on the frame assembly 1.

[0052] Preferably, both axial ends of the bearing 8 are provided with skeleton rubber sealing rings, which reduces the maintenance and replacement frequency of the bearing 8 and is convenient for maintenance.

[0053] In some embodiments, the frame assembly 1 includes a base 11 and a mounting bracket 12. A bearing 8 is provided at one end of the mounting bracket 12, and the other end of the mounting bracket 12 is connected to the base 11. The mounting bracket 12 is movable relative to the base 11 to adjust the distance between the measuring gear 3 and the base 11.

[0054] As Figure 1 and Figure 2As shown, the base 11 extends in the vertical direction. The top of the base 11 is used for welding or installing and fixing the base 11 through connecting parts such as bolts. The bottom of the base 11 is connected to the mounting frame 12. The mounting frame 12 extends in the left - right direction. The left end of the mounting frame 12 has a sleeve part. The sleeve part is a cylindrical shape surrounding a vertical square. The upper parts of two bearings 8, a retaining ring 9, a second bushing 10, and a first bushing 10 are all located within the sleeve part. The outer rings of the two bearings 8 are connected to the inner circumferential surface of the sleeve part. The measuring gear 3 is located below the sleeve part. The coupling 7 is located below the sleeve part. All or part of the upper part of the rotating shaft 2 is inserted into the sleeve part and is connected to the coupling 7. The lower part of the rotating shaft 2 extends below the sleeve part and is connected to the measuring gear 3.

[0055] Preferably, the bottom of the base 11 is connected to the right end of the mounting frame 12 through connecting parts such as bolts, and several gaskets 14 are provided between the bottom of the base 11 and the right end of the mounting frame 12. By adjusting the number of gaskets 14, the position of the mounting frame 12 relative to the base 11 in the left - right direction can be adjusted, so as to adjust the distance between the measuring gear 3 and the base 11, thereby adjusting the meshing state between the measuring gear 3 and the gear to be measured 4, facilitating the meshing installation of the measuring gear 3 and the gear to be measured 4, and improving the meshing transmission accuracy between the measuring gear 3 and the gear to be measured 4.

[0056] In some embodiments, the frame assembly 1 further includes a support frame 13. The support frame 13 is detachably arranged on the mounting frame 12, and a revolution counter 5 is provided on the support frame 13.

[0057] As Figures 1-3 shown, the support frame 13 is an inverted U - shaped plate. The two U - shaped ends of the support frame 13 are respectively connected to the mounting frame 12 through connecting parts such as bolts and are located above the sleeve part, so that the support frame 13 is detachably connected to the mounting frame 12. The revolution counter 5 is installed on the top of the support frame 13 through connecting parts such as bolts, which is convenient for the replacement and maintenance of the revolution counter 5. The coupling 7 is located within the space surrounded by the U - shape of the support frame 13 and is connected between the top of the rotating shaft 2 and the shaft end of the rotating shaft 2. In other words, the coupling 7 is externally exposed, so as to facilitate observing the connection state between the coupling 7 and the rotating shaft 2, and between the coupling 7 and the revolution counter 5 and for installation and maintenance.

[0058] At the same time, the detachable connection between the support frame 13 and the mounting frame 12 also facilitates detaching the support frame 13 to separate the revolution counter 5 from the frame assembly 1, thereby facilitating the replacement and maintenance of the revolution counter 5.

[0059] As Figures 1-5 shown, the detachable cableway of the embodiment of the present utility model includes a driving wheel and a gear revolution measuring device.

[0060] The outer peripheral surface of the driving wheel has gear teeth. The gear rotation speed measuring device is the gear rotation speed measuring device of the embodiment of the utility model. The measuring gear 3 is meshed and connected with the gear teeth of the driving wheel.

[0061] Specifically, the outer peripheral surface of the driving wheel has gear teeth. In other words, the driving wheel adopts a gear structure and serves as the gear 4 to be measured. The driving wheel is meshed and connected with the measuring gear 3. When the detachable ropeway is running, the driving wheel rotates and drives the measuring gear 3 and the rotating shaft 2 to rotate. The speed measuring device 5 measures the speed of the measuring gear 3 and the rotating shaft 2, thereby indirectly measuring the speed of the driving wheel to obtain the running speed and running state of the driving wheel, ensuring the smooth operation and safety of the detachable ropeway. At the same time, the vibration of the driving wheel during operation will not cause the speed measuring device 5 to miss reading or misread, thereby ensuring the accuracy of the measurement.

[0062] The detachable ropeway of the embodiment of the utility model has the gear speed measuring device of the embodiment of the utility model.

[0063] It can be understood that the driving wheel is not limited to being connected to the measuring gear by meshing transmission as the gear to be measured. In other embodiments, the driving wheel is provided with a coaxially arranged transmission wheel, and the transmission wheel rotates synchronously with the driving wheel. The transmission wheel is connected to the measuring gear by meshing transmission as the gear to be measured, and the number of revolutions of the driving wheel can also be obtained by a gear revolution measuring device.

Then the mounting frame 12 is pre-connected with the base 11, and the installation position of the base 11 on the structural beam is determined according to the meshing transmission connection requirements of the measuring gear 3 and the driving wheel, and the base 11 is welded to the structural beam or connected by bolts and other connecting parts, and then the position of the mounting frame 12 relative to the base 11 is adjusted by setting the gasket 14 and adjusting the number of the gaskets 14 to ensure the meshing transmission connection state of the measuring gear 3 and the driving wheel, and the mounting frame 12, the base 11 and the gasket 14 are installed and fixed. Finally, the support frame 13, the speed measuring device 5 and the coupling 7 are assembled, and the support frame 13 is connected to the mounting frame 12, and the coupling 7 is connected to the rotating shaft 2. It is understandable that the base 11 is not limited to being arranged on the structural beam. In other embodiments, the base 11 may also be arranged on a driving device that drives the driving wheel, or on a detection device of the driving device.

[0065] Preferably, there are at least two gear rotation speed measuring devices, and the at least two gear rotation speed measurements are arranged at intervals along the circumferential direction of the driving wheel, so as to mutually verify the measurement results of all the gear rotation speed measuring devices, ensure the accuracy of the measurement results, and avoid no measurement results caused by damage to some of the gear rotation speed measuring devices.
