Abstract
The utility model discloses a depth indicator. The depth indicator comprises a machine frame, and further comprises an upper indicating screw rod and a lower indicating screw rod, wherein the upper indicating screw rod and the lower indicating screw rod are vertically installed on the machine frame through corresponding bearing sleeves respectively; indicators are installed on the upper indicating screw rod and the lower indicating screw rod; dial gauges matched with the indicators are arranged on the machine frame; a dual gear and a spur gear are positioned at the lower ends of the upper indicating screw rod and the lower indicating screw rod respectively and are meshed with each other; a transmission device is arranged on the machine frame; and a transmission gear and a dual gear of the transmission device are meshed with each other. The depth indicator has the advantages as follows: 1, simple structure and easiness in manufacturing: compared with a well-known depth indicator, the depth indicator disclosed by the utility model omits a worm gearbox and a complicated reversing mechanism, so that the structure is simplified, and the manufacturing difficulty is obviously reduced, while the functional effects are the same; 2, convenience in maintenance: working parts of the depth indicator are few and visible, so that the working parts are very convenient to replace and maintain; and 3, low manufacturing cost: experiments prove that the production cost of the depth indicator is only 1/3 of that of the well-known product, with very prominent economic benefit.
Description
Technical field
The utility model relates to the pit gear technical field, refers in particular to a kind of 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 of band worm and gear to carry out the speed change switching-over; Through switching mechanism the motion conditions of winch is converted into left-hand rotation of two screw rods simultaneously; Indicating device in the rotation of a right-hand rotation, two screw rods moves up or down respectively when screw rod rotates, and the data from the corresponding scale strip of indicating device are confirmed 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, and cost is high, and assembling and maintenance are inconvenient.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of simple in structure, depth indicator that is used to indicate mine hoisting device run location that cost is low, easy to maintenance is provided.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of depth indicator, and it includes frame, and it also includes the indication screw rod, indicates screw rod down; Wherein, indicate on screw rod and following indication screw rod respectively the cooresponding bearing carrier ring of green phase vertically be installed on the frame; Last indication screw rod, indicate indicating device all is installed on the screw rod down, frame is provided with the graduation apparatus that matches with indicating device; Dual gear, spur gear lay respectively at the indication screw rod, indicate the screw rod lower end down, and are meshing with each other; Frame is provided with driving device, and the transmission gear of driving device is meshed with dual gear.
Described frame is provided with and is used to control the arrangement of clutch that dual gear, spur gear and driving device are used.
The described indication screw rod of going up is opposite with the hand of rotation of following indication screw rod.
Described frame is provided with telltale.
Described indicating device is installed in the indication screw rod, indicates on the screw rod down through circular nut.
The advantage of the utility model is: 1, simple in structure, be easy to make: this programme is than the change speed gear box and the complicated direction reverser that have omitted the band worm and gear in the known technology, designs simplification, and manufacture difficulty obviously reduces, and functional effect is identical.2, easy to maintenance: the working part in this programme is few, and all is in visible location, and repair and replacement are very convenient.3, low cost of manufacture: through experimental verification, the productive costs of this programme is merely 1/3 of known technology cost of product, and economic benefit is very outstanding.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model.
Fig. 2 is the A-A cut-away view among Fig. 1.
Fig. 3 is that B among Fig. 2 is to scheme drawing.
The specific embodiment
Below in conjunction with institute's drawings attached the utility model is described further; The preferred embodiment of the utility model is: referring to accompanying drawing 1 to accompanying drawing 3; The described depth indicator of present embodiment include frame 1, on indicate screw rod 2, indicate screw rod 10 down; Wherein, indicate on screw rod 2 and indication screw rod 10 down respectively the cooresponding bearing carrier ring 11 of green phase vertically be installed on the frame 1; And the hand of rotation of going up indication screw rod 2 and following indication screw rod 10 after installing is opposite.Last indication screw rod 2, indicate indicating device 3 all is installed on the screw rod 10 down, indicating device 3 is installed in indication screw rod 2, indicates on the screw rod 10 down through circular nut 12; Frame 1 is provided with the graduation apparatus 4 that matches with indicating device 3; Dual gear 5, spur gear 6 lay respectively at indication screw rod 2, indicate screw rod 10 lower ends down, and are meshing with each other; Frame 1 is provided with driving device 8; The transmission gear of driving device 8 is meshed with dual gear 5; When winch drive transmission 8 rotated, driving device 8 drove dual gear 5 and rotates, and indication screw rod 2 rotates thereby drive upward; Make the indicating device that is positioned on the indication screw rod 2 carry out corresponding moving up or down, just can learn the depth location of bont from cooresponding scale strip data.Dual gear 5 drive spur gears 6 rotate simultaneously, make spur gear 6 drives indication screw rod 10 rotations down, and indicating device and the indicating device on the last indication screw rod 2 under driving simultaneously on the indication screw rod 10 carry out counter motion; Also be provided with the arrangement of clutch 7 that is used to control dual gear 5, spur gear 6 and driving device 8 usefulness on the frame 1, arrangement of clutch 7 can make driving device 8 separate with dual gear 5 or mesh, and is convenient to depth indicator and keeps in repair and debug.Frame 1 is provided with telltale 9, when indicating device 3 moves to telltale 9 positions, triggers telltale 9 and produces relevant control action, like upper and lower deceleration, warning work such as upper and lower parking, helps improving the automation and the device security of winch.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
