Description

Technical Field

[0001] The utility model belongs to the technical field of cableway equipment, and in particular relates to an anti-dropping limiting structure for a gear on a speed measuring motor for a reciprocating cableway. Background Art

[0002] The driving wheel used on the cableway is driven to rotate by the driving motor. At the same time, a speed measuring motor is installed on the equipment to monitor the speed of the equipment and transmit the signal for people's reference. The rotation connection structure of the speed measuring motor is to set a large gear, which is driven by the driving motor. A small gear is provided on the output shaft of the speed measuring motor. The small gear and the large gear are meshed with each other. The rotation of the large gear drives the small gear to rotate, and the small gear drives the speed measuring motor to rotate, thereby outputting a speed signal. Among them, the small gear is sleeved on the output shaft of the speed measuring motor, and the outer end is fixed by a gasket and a fixing nut. Due to the long-term use of the speed measuring motor, the gasket, fixing nut and other components will loosen under the influence of long-term wear and high temperature, which will cause the small gear to fall off the output shaft of the speed measuring motor, posing a great safety hazard. Therefore, it is necessary to propose improvements. Utility Model Content

The utility model aims to prevent the small gear from slipping off the output shaft, prevent the occurrence of safety hazards, and provide workers with sufficient time to discover abnormal situations.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The gear anti-slipping limiting structure on the speed measuring motor for a reciprocating cableway comprises a speed measuring motor mounting seat, the speed measuring motor is fixedly connected to the speed measuring motor mounting seat, a pinion is fixedly sleeved on the output shaft of the speed measuring motor, the pinion is meshed with a large gear driven by the cableway, a washer and a fixing nut for limiting and fixing the pinion are provided on the outer end of the output shaft, a gear anti-slipping baffle structure for preventing the pinion from slipping off the output shaft is provided at the front part of the outer end of the output shaft, and one end of the gear anti-slipping baffle structure is fixedly connected to the speed measuring motor mounting seat.

[0006] Further limiting the above scheme, the gear anti-slip baffle structure is formed by connecting the anti-slip baffle, the horizontal connecting plate and the vertical connecting plate in sequence. The anti-slip baffle is placed in front of the output shaft of the speed measuring motor, the edge of the anti-slip baffle is larger than the inner hole diameter of the pinion, and the vertical connecting plate is fixedly connected to the vertical mounting plate of the speed measuring motor mounting seat by connecting bolts.

[0007] To further limit the above scheme, a circular anti-detachment platform is provided on the side of the anti-detachment baffle plate close to the output shaft of the speed measuring motor, and after the gear anti-detachment baffle plate structure is installed on the speed measuring motor mounting seat, the circular anti-detachment platform is coaxial with the output shaft, and the diameter of the circular anti-detachment platform is larger than the inner hole diameter of the pinion gear.

[0008] As a further limitation of the above scheme, a reinforcing connecting plate I is provided between the anti-slip baffle and the transverse connecting plate, and a reinforcing connecting plate II is provided between the transverse connecting plate and the vertical connecting plate.

[0009] The advantages of this utility model compared with the prior art:

[0016] See also Figure 1-3 , describe the embodiments of the present utility model in detail.

[0017] Embodiment: Anti-dropping limit structure of upper gear of speed measuring motor for reciprocating ropeway, see Figure 1 As shown, there is a speed measuring motor mounting seat 1, to which a speed measuring motor 2 is fixedly connected, and a pinion 4 is fixedly sleeved on the output shaft 3 of the speed measuring motor 2, and the pinion 4 is meshed with a cableway driving gear 7, and a washer 5 and a fixing nut 6 for limiting and fixing the pinion 4 are provided on the outer end of the output shaft 3, and a gear anti-detachment baffle structure 8 for preventing the pinion 4 from escaping from the output shaft 3 is provided at the front part of the outer end of the output shaft 3, and one end of the gear anti-detachment baffle structure 8 is fixedly connected to the speed measuring motor mounting seat 1.

[0018] The utility model provides a gear anti-detachment baffle structure at the front part of the outer end of the output shaft of the speed measuring motor. When the gasket and the fixing nut of the fixed small gear are loosened, the gear anti-detachment baffle structure can block the fixing nut and the gasket to prevent the small gear from immediately detaching from the output shaft, thereby preventing the occurrence of safety hazards and providing sufficient time for the staff to discover abnormal situations.

[0019] In a specific implementation: see 2, Figure 3 As shown, the gear anti-slip baffle structure 8 is formed by connecting the anti-slip baffle 8-1, the horizontal connecting plate 8-2 and the vertical connecting plate 8-3 in sequence. Structure, the anti-slip baffle 8-1 is placed in front of the output shaft 3 of the speed measuring motor 2, the edge of the anti-slip baffle 8-1 is larger than the inner hole diameter of the pinion 4, and the vertical connecting plate 8-3 is fixedly connected to the vertical mounting plate of the speed measuring motor mounting base 1 by connecting bolts 8-7.

[0020] With the above structure, when the pinion gear is loose and about to come out axially, the anti-come-off baffle 8-1 will block it and prevent it from coming out, so that the pinion gear can continue to work until the staff finds it and repairs it.

[0021] Preferably, see Figure 3 As shown, a circular anti-detachment platform 8-4 is provided on the side of the anti-detachment baffle 8-1 close to the output shaft 3 of the speed measuring motor 2. After the gear anti-detachment baffle structure 8 is installed on the speed measuring motor mounting seat 1, the circular anti-detachment platform 8-4 is coaxial with the output shaft 3, and the diameter of the circular anti-detachment platform 8-4 is larger than the inner hole diameter of the pinion 4.

[0022] The above structure can achieve a better blocking effect on the pinion by providing a circular anti-slip block.

[0023] In a specific implementation: see 2, Figure 3As shown, a reinforcing connecting plate I8-5 is provided between the anti-slip baffle 8-1 and the horizontal connecting plate 8-2, and a reinforcing connecting plate II8-6 is provided between the horizontal connecting plate 8-2 and the vertical connecting plate 8-3.

[0024] Through the above structure, the strength of the gear anti-slip baffle structure is improved, and it is not easy to deform under the action of the axial external force generated by the axial sliding of the pinion.
