Problems solved by technology

Oxidation prevention measures cannot be implemented due to limitations of use conditions
In particular, the underground environment of mines is even harsher, and oil-free steel wire ropes are more likely to be corroded and damaged, so the service life is short, and the workload of maintenance and replacement of steel wire ropes is heavy, which affects production and causes high cost of use.
The cable grip is the load-bearing connector of the overhead passenger device. In order to meet the needs of various environmental conditions, the safety brake of the existing overhead passenger device is set at the beginning of the transmission system (that is, on the input shaft of the reducer) and its The brake is a hydraulic push rod brake, which can only achieve locked-rotor impact braking. Once the gears in the transmission system fail, the transmission terminal will run out of control and fly, which will endanger the safety of people and equipment.
Due to the limitation of the structure of the rope grip, the rope support wheel of the existing overhead passenger device can only use a single semi-axis rope rope structure, which will cause vibration due to the change of the torsional stress of the wire rope and the height difference between the rope grip and the wire rope. , the phenomenon of rope drop still exists
There are many types of grips, and movable grips are widely used in underground mines. The connection between the movable grip and the steel wire rope adopts the self-weight hanging pressure connection method, and the self-weight friction resistance torque is used to be driven by the steel wire rope. However, it is limited by the gradient of the transport moment. Slip phenomenon occurs from time to time, the reliability is poor, the ride is uncomfortable, and the safe operation is greatly reduced

Embodiment Construction

[0034] A kind of soft-start stepless speed regulation loop chain load-carrying traction overhead passenger device, such asfigure 1 As shown, the base including the planetary differential stepless speed regulator 1 is fixed on the frame, such as Figure 4 As shown, one end of the sun gear shaft 6 is fitted with a bearing, which is positioned in the inner hole at one end of the machine base. The other end of the wheel shaft 6 is fitted with a bearing, which is positioned in the inner hole at one end of the planetary carrier 7. The external gear at the protruding end meshes with the internal teeth of the internal and external sun gear 5 to form a backlash float. The external gear of the internal and external sun gear 5 and the The planetary gear 4 located in the planetary carrier 7 is externally meshed, the planetary gear 4 is internally meshed with the differential internal gear 3, and one end of the differential internal gear 3 is in contact with the external tooth end teeth of ...

Abstract

The invention discloses a soft starting stepless speed regulation loop chain carrying traction aerial cableway, which aims at solving the problems that the system impact of the existing aerial cableway is strong, the abrasion of a driving friction lining block is accelerated, a transmission system fails in an early period, and the like. The aerial cableway comprises a planet differential steplessspeed regulator, wherein an output shaft of the planet differential stepless speed regulator is connected with a crossed axis angle speed reducer through a shaft coupler, a belt brake disc driving chain wheel is arranged on an output shaft of the crossed axis angle speed reducer, the belt brake disc driving chain wheel is in engaged transmission with an annular chain, in addition, the annular chain is in engaged transmission with a machine tail tensioning chain wheel, and a combined hanging hook assembly is connected onto the annular chain. The soft starting stepless speed regulation loop chain carrying traction aerial cableway has the advantages that the idle load starting of a motor is realized, a work mechanism adopts soft starting, stepless speed regulation and soft stop, the loop chain is in engaged transmission, traction carrier elements are in duplex guide operation, the carrying capability is high, the transmission efficiency is high, the structure is simple, the manufacturingcost and the use cost are low, and safety and reliability are realized.

Description

technical field [0001] The invention relates to the field of people-carrying devices, in particular to a soft-start stepless speed-regulating ring chain load-bearing traction overhead passenger device. technical background [0002] Aerial passenger device (commonly known as cableway) is a kind of transportation equipment that does not require high ground conditions and is indispensable for transporting personnel or materials when other transportation equipment cannot carry personnel or materials. The characteristics of this kind of transportation equipment are: occupying a small space on the ground, it can realize the roundabout and continuous transportation of airborne traction, it is easy to realize the three-dimensional interlaced transportation system of different types of transportation equipment in the air and on the ground, and the investment cost is low. Because of its unique characteristics, it is widely used in mines. Widely used in underground roadways. However, ...
