Conevying efficiency has great significance.Therefore, it is flat to develop a kind of single cylinder pulley blocks formula promotion applied to Open TBM
Platform is always new issue anxious to be resolved.
Utility model content
The purpose of this utility model is to provide a kind of single cylinder pulley blocks formulas applied to Open TBM to promote platform,
The utility model is simple in structure, and securely and reliably, the double cylinder types promotion platform promotion that can be solved in previous engineering project is asynchronous
The problem of, lift stroke can be made to be twice of oil cylinder stroke using oil cylinder pulley block structure, it, can while reducing oil cylinder cost
Keep promotion platform structure more compact, substantially increases the adaptability for promoting platform in different digging diameter Open TBMs.
What the purpose of this utility model was realized in：A kind of single cylinder pulley blocks formula applied to Open TBM is promoted
Platform, including the first fixed pulley, safety screen, platform, the second fixed pulley, third fixed pulley, oil cylinder, sliding block, the 4th fixed pulley,
5th fixed pulley, first support, second support, limit sensors, cushion pad, fixed seat, the first steel wire rope, the second steel wire rope,
Safety screen oil cylinder, first support and second support are welded on Open TBM material bridge A, and oil cylinder and sliding block are fixed on platform
Bottom, first steel wire rope one end are fixed in first support, and the other end sequentially bypasses the first fixed pulley, third fixed pulley, the 4th
Fixed pulley, sliding block are finally fixed in fixed seat, and second steel wire rope one end is fixed on holder, the second steel wire rope other end sequentially around
The second fixed pulley, the 5th fixed pulley, sliding block is crossed to be finally fixed in fixed seat；First fixed pulley and the second fixed pulley are fixed respectively
In first support and second support, third fixed pulley, the 4th fixed pulley and the 5th fixed pulley are fixed on platform, safety screen
Oil cylinder is connect with safety screen, and oil cylinder is connect with sliding block, and limit sensors are connect with cushion pad.
The utility model is characterized by its structure.Its operation principle and operating method are, when platform is located at low level, oil
Cylinder is fully extended, and when promotion, oil cylinder is gradually retracted, and passes through sliding block and steel wire rope, steel wire rope pull platform to rise.Sliding block can be regarded as
Movable pulley, when oil cylinder is retracted, platform hoisting depth is two times of oil cylinder stroke, and promoting platform compared to previous double cylinder types can
Save the oil cylinder stroke of half so that structure is more compact, and it is nonsynchronous that single cylinder structure can solve the problems, such as that double oil cylinders are promoted, and carries
High material transportation efficiency.Safety screen is installed on platform, safety screen can be realized in 180 ° of models by safety screen oil cylinder
Enclose interior rotation.Respectively there is the gentle punching pad of limit sensors in the upper and lower ends of holder, when operating mode badly causes limit sensors to damage
When, since the effect of cushion pad reduces the impact for promoting platform in promotion or decline to greatest extent, it ensure that the utility model
It is safe and reliable.
A kind of single cylinder pulley blocks formula applied to Open TBM promotes platform compared with prior art, has single cylinder
It is nonsynchronous that structure can solve the problems, such as that double oil cylinders are promoted, and improve material transportation efficiency, peace can be realized by safety screen oil cylinder
Full baffle rotates within the scope of 180 °, and cushion pad reduces the impact for promoting platform in promotion or decline to greatest extent, ensures peace
It the advantages that complete reliable, will be widely used in rock tunnel(ling) machine technical field.
Description of the drawings
The utility model is described in detail with reference to the accompanying drawings and embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Specific implementation mode
With reference to attached drawing, a kind of single cylinder pulley blocks formula promotion platform applied to Open TBM, including the first fixed pulley 1,
Safety screen 2, platform 3, the second fixed pulley 4, third fixed pulley 5, oil cylinder 6, sliding block 7, the 4th fixed pulley 8, the 5th fixed pulley 9,
First support 10, second support 11, limit sensors 12, cushion pad 13, fixed seat 14, the first steel wire rope 15, the second steel wire rope
16, safety screen oil cylinder 17, first support 10 and second support 11 are welded on Open TBM material bridge A, oil cylinder 6 and sliding block 7
Be fixed on 3 bottom of platform, 15 one end of the first steel wire rope is fixed in first support 10, the other end sequentially bypass the first fixed pulley 1,
Third fixed pulley 5, the 4th fixed pulley 8, sliding block 7 are finally fixed in fixed seat 14, and 16 one end of the second steel wire rope is fixed on holder
