Description
Technical field
The present invention relates to a kind of depth indicator, particularly a kind of memorial archway type depth indicator that is used to indicate mine hoisting device run location.
Background technology
At present, known depth indicator mostly adopts the change speed gear box (reductor) of band worm and gear to carry out the speed change commutation, the motion conditions of winch is converted into the rotation of screw rod, indicating device on the screw rod moves up and down when screw rod rotates, and the data from the corresponding scale strip of indicating device are determined the depth location of bont mine.This technical scheme complex structure, especially the change speed gear box difficulty of processing with worm and gear is big, the cost height, assembling and maintenance are inconvenient, and safety factor is low.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and provide a kind of simple in structure, cost is low, easy to maintenance, the memorial archway type depth indicator that safety alarm device is perfect is used to indicate mine hoisting device run location.
Technical scheme of the present invention is: a kind of memorial archway type depth indicator; comprise frame; screw mandrel; large conical gear; small conical gear; main shaft; lower sensor; upper sensor; circular nut and clutch equipment; screw mandrel is installed on the frame; large conical gear is installed in the screw mandrel bottom; small conical gear is installed on the main shaft and with large conical gear and meshes; sprocket wheel is installed on the main shaft; it is bottom and top that lower sensor and upper sensor are installed in frame respectively; have on the lower sensor and play the deceleration protection respectively; the retarding travel switch of speed-limiting protection and overtravel protection effect; speed limit travel switch and overtravel protection travel switch; upper sensor also has and plays deceleration protection respectively; the retarding travel switch of speed-limiting protection and overtravel protection effect; speed limit travel switch and overtravel protection travel switch; circular nut is installed on the screw mandrel by negative thread, and position indicator is housed on it.
The further technical scheme of the present invention is: large conical gear is separated or meshing clutch equipment comprises handle, shift fork, stay bearing plate and declutch shift shaft with small conical gear, handle is installed in the outer end of shift fork, shift fork is installed on the frame by stay bearing plate and declutch shift shaft, and is connected with large conical gear.
The further again technical scheme of the present invention is: the screw mandrel top also is equipped with rotary encoder.
The present invention is owing to adopt as above design, compared with prior art, has simple in structurely, and cost of manufacture is low, assembling and easy to maintenance, and safety alarm device is perfect, and characteristics such as safety factor height are specially adapted to indicate the run location of mine hoisting device.
Below in conjunction with the drawings and specific embodiments detailed content of the present invention is further described.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1: a kind of memorial archway type depth indicator, by frame 1, screw mandrel 2, large conical gear 3, small conical gear 4, main shaft 5, lower sensor 6, upper sensor 7, circular nut 8 and clutch equipment are formed, screw mandrel 2 is installed on the frame 1, large conical gear 3 is installed in screw mandrel 2 bottoms, small conical gear 4 is installed on the main shaft 5 and with large conical gear 3 and meshes, sprocket wheel 51 is installed on the main shaft 5, it is bottom and top that lower sensor 6 and upper sensor 7 are installed in frame 1 respectively, have on the lower sensor 6 and play the deceleration protection respectively, the retarding travel switch 61 of speed-limiting protection and overtravel protection effect, speed limit travel switch 62 and overtravel protection travel switch 63, upper sensor 7 also has and plays deceleration protection respectively, the retarding travel switch 71 of speed-limiting protection and overtravel protection effect, speed limit travel switch 72 and overtravel protection travel switch 73, circular nut 8 is installed on the screw mandrel 2 by negative thread, and position indicator 81 is housed on it; Large conical gear 3 is separated or meshing clutch equipment comprises handle 91, shift fork 92, stay bearing plate 93 and declutch shift shaft 94 with small conical gear 4, handle 91 is installed in the outer end of shift fork 92, shift fork 92 is installed on the frame 1 by stay bearing plate 93 and declutch shift shaft 94, and is connected with large conical gear 3; Screw mandrel 2 tops also are equipped with rotary encoder 21.
During work, will pass to main shaft 6 from the power that chain 51 transmits, pass to large conical gear 3 by the small conical gear on the main shaft 64 again, and drive screw mandrel 2 and rotate by sprocket wheel 5.
When gig was descending, the circular nut 8 on the screw mandrel 2 moved downward along screw mandrel 2, when circular nut 8 arrives decelerate position, and 61 actions of retarding travel switch, gig jingle bell warning this moment is also slowed down descending; When circular nut 8 arrives the speed limit position, 62 actions of speed limit travel switch, gig continues to slow down descending, when this moment, the gig rope speed surpassed 2m/s, then speed relay action, cut off gig master motor power, each valve of Hydraulic Station is successively moved by the safety arrestment requirement, make gig realize safety arrestment and stop; When surpassing normal terminal stop position 0.5m as gig, the circular nut 8 on the screw mandrel 2 arrives the pulleying positions, 63 actions of overtravel protection travel switch, and gig cuts off the safety return circuit in automatically controlled automatically, and gig is realized emergency braking.
When gig promoted, the circular nut 8 on the screw mandrel 2 was along screw mandrel 2 upward movements, and when circular nut 8 arrived decelerate position, retarding travel switch 61 moved, and the gig jingle bell was reported to the police and also slowed down descending this moment; When circular nut 8 arrives the speed limit position, 62 actions of speed limit travel switch, gig continues to slow down descending, when this moment, the gig rope speed surpassed 2m/s, then speed relay action, cut off gig master motor power, each valve of Hydraulic Station is successively moved by the safety arrestment requirement, make gig realize safety arrestment and stop; When surpassing normal terminal stop position 0.5m as gig, the circular nut 8 on the screw mandrel 2 arrives the pulleying positions, 63 actions of overtravel protection travel switch, and gig cuts off the safety return circuit in automatically controlled automatically, and gig is realized emergency braking.
