Abstract
The present utility model provides a mining explosion proof type combined switch mechanical drive mechanism. The mechanism is characterized in that the mechanism comprises a propulsion plate, an eccentric propulsion cam is arranged above the propulsion plate, a linear guide rail is respectively arranged on left and right sides of the propulsion cam, two sliding pedestals are stretched across the linear guide rails, the two sliding pedestals are respectively arranged on front and rear sides of the propulsion cam and connected with the propulsion plate, a horizontally arranged driven bevel gear is sleeved on a rotary shaft of the propulsion cam, a rotary main shaft is arranged above the propulsion cam, a vertically arranged active bevel gear is sleeved on the rotary main shaft, and the driven bevel gear is engaged with the active bevel gear. In the module propulsion structure, the rotary main shaft can be operated to rotate 120 degrees, the active bevel gear can be driven to rotate 120 degrees, the cam is driven by the driven bevel gear to rotate, a rotary movement is converted into a linear movement, modules are driven by the propulsion plate to pass in and out, the structure is compact and reliable, the operation is flexible, and the mechanism accords with operation methods of workers.
Description
Technical field
The utility model relates to the mechanically combining blocking mechanism of the modular unit switch of a kind of flame-proof type.
Background technology
The body and the binding post of flame-proof type switch are main with thread connecting mode at present, also have to isolate the pattern that latch is controlled single circuit switching.At present, the shortcoming of unit switch is: can not realize the plug of the switch module of modularization and modularization, can not plug any one or more modules in the explosion-proof chamber as required.
Summary of the invention
The purpose of the utility model is to provide a kind of mechanical transmission mechanism, plugs any one or more module through this mechanism as required in flame proof housing external enwergy.
In order to achieve the above object, the technical scheme of the utility model has provided a kind of mechanical transmission mechanism of flame-proof mine unit switch, it is characterized in that: comprise pushing plate; Eccentric propelling cam is located at the top of pushing plate; The left and right sides advancing cam is respectively equipped with linear guide rail, and two sliding seats are across on line slideway, and two sliding seats lay respectively at the both sides, front and back that advance cam and link to each other with pushing plate; On the rotation axis that advances cam, be with a horizontally disposed driven wheel of differential; Above the propelling cam, be provided with a rotary main shaft, rotary main shaft is the drive bevel gear that is with vertical setting, and driven wheel of differential is meshed with drive bevel gear.
Further, said propelling cam is a peach shape.
A kind of module propulsive mechanism that the utility model provides; The rotation of operation rotary main shaft drives 120 ° of drive bevel gear rotations for 120 °, and driven wheel of differential drives cam and revolves, and will rotatablely move converts rectilinear motion into; Drive the module turnover by pushing plate; Its compact conformation is reliable, and flexible operation meets workman's method of operation.
Description of drawings
Fig. 1 looks partial sectional view for the mechanical transmission mechanism master of a kind of flame-proof mine unit switch that the utility model provides;
The mechanical transmission mechanism vertical view of a kind of flame-proof mine unit switch that Fig. 2 provides for the utility model.
Embodiment
Like Fig. 1 and shown in Figure 2; The mechanical transmission mechanism of a kind of flame-proof mine unit switch that provides for the utility model comprises pushing plate 4, and eccentric propelling cam 3 is located at the top of pushing plate 4; The left and right sides advancing cam 3 is respectively equipped with linear guide rail 6; Two sliding seats 5 are across on line slideway 6, and two sliding seats 5 lay respectively at the both sides, front and back that advance cam 3 and link to each other with pushing plate 4, on the rotation axis of propelling cam 3, are with a horizontally disposed driven wheel of differential 7; Above propelling cam 3, be provided with a rotary main shaft 1; Rotary main shaft 1 is for being with the drive bevel gear 2 of vertical setting, and driven wheel of differential 7 is meshed with drive bevel gear 2, and advancing cam 3 is peach shape.
Utilize shaft coupling that rotary main shaft 1 is driven 120 ° of drive bevel gear 2 rotations, drive by driven wheel of differential 7 and advance cam 3 rotations, utilize to advance cam 3 to drive pushing plate 4 moving linearlies.Utilize the groove on the pushing plate 4 just can drive the module moving linearly, realize the plug of module.
This mechanism needs only supporting bracket 8 lengthenings in front and back can be advanced 3 modules, and can adorn the mechanism that a plurality of the utility model provide in the same explosion-proof chamber, and independent assortment is realized the seriation of switch as required.
