Mechanical type lifting device with rack-and-pinion climbing structure
Art
The present invention relates to a kind of lowering or hoisting gear, more precisely a kind of mechanical elevating with rack-and-pinion climbing structure Device.
Background technology
In actual industrial production, it is often necessary to according to different requirements, adjust the height of workpiece, therefore elevating mechanism is wide It is general to be applied to various industries, but the lowering or hoisting gear of prior art, complicated, installation difficulty, complex operation, operating are shaken, Manufacturing cost is high, it is often necessary to maintenance, to manufacturer and with putting to no little inconvenience per family.
In order to overcome the shortcomings of that existing lifting device structure is complicated, manufacturing cost is high, the present invention provides a kind of lowering or hoisting gear, The lowering or hoisting gear carries rack-and-pinion climbing structure, by the rotation of gear realize lowering or hoisting gear rising, decline with it is static.
The content of the invention:
The purpose of the present invention mainly solves the problems of prior art, so as to provide a kind of simple in construction, installation Conveniently, operation is easy, operating is stable, the mechanical type lifting device that cost is relatively low, safe and reliable.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals:
It is a kind of to be connected with gear, the mechanical type lifting device of rack roof lifting structure, its motor with gear, gear and tooth Bar is meshed connection, and circle is supported and fixed on upper table surface bottom, and the upper end fulcrum of interior arm support and boom is arranged on upper table surface, outside The strong point is fixed under upper table surface by bearing block on arm support, can only be rotated, and the strong point can be in upper table surface guide rail on interior arm support Upper rolling.The lower sustainer of interior arm support and boom is arranged on following table, and the strong point rolls on following table guide rail under boom Dynamic, the strong point is fixed on following table by bearing block and can only rotated under interior arm support.Reed organ type dust-proof cover is arranged on upper following table Between, play safe, attractive in appearance, dust-proof effect.
During elevator duty, motor driven gear rotates, and gear drives the rack of engagement to run up and down, and rack upper end is withstood on In the circle support of upper table surface, when rack is run up, circle support is run up, and upper table surface rises;When rack is run downwards, appear on the stage Face uniform descent under own wt effect, the rise and fall of lowering or hoisting gear are realized, then lowering or hoisting gear is run pinion rotation, tooth Take turns the then lowering or hoisting gear remains stationary that stops operating.
The beneficial effects of the invention are as follows:Lowering or hoisting gear have simple in construction, easy for installation, operation easily, operating it is stable, into The advantages that this is relatively low, safe dustproof.
Brief description of the drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Accompanying drawing is the structural representation of the lowering or hoisting gear with rack-and-pinion climbing structure of the present invention.
As illustrated, 1. upper table surface in figure, 2. circles support, arm support in 3., 4. booms, 5. following tables, 6. gears, 7. teeth Bar, 8. motors, 9. reed organ type dust-proof covers.
Embodiment
In figure, motor (8) is connected with gear (6), and gear (6) is meshed with rack (7) and is connected, circle support (2) peace Mounted in upper table surface (1) bottom, the upper end fulcrum of interior arm support (3) and boom (4) is arranged on upper table surface (1), boom (4) The upper strong point is fixed on upper table surface (1) bottom by bearing block, can only rotate, and the strong point can be in upper table surface on interior arm support (3) (1) rolled on guide rail.The lower sustainer of interior arm support (3) and boom (4) is arranged on following table (5), and boom supports under (4) Point is rolled on following table (5) guide rail, and the strong point is fixed on following table (5) by bearing block and can only rotated under interior arm support (3). Reed organ type dust-proof cover (9) is arranged between upper table surface (1) and following table (5).During elevator duty, motor (8) band moving gear (6) Operating, gear (6) drive the rack (7) of engagement to run up and down, and rack (7) upper end is withstood in the circle support (2) of upper table surface (1), When rack (7) is run up, circle support (2) is driven to run up, upper table surface (1) rises;When rack (7) is run downwards, appear on the stage Face (1) is because own wt acts on uniform descent, so as to realize the rise and fall of lowering or hoisting gear.Gear (6) rotates, then lifting dress Operation is put, gear (6) stops operating, then lowering or hoisting gear remains stationary.
Organ type used in a kind of mechanical type lifting device with rack-and-pinion climbing structure of the present invention is dust-proof Covering (9) is formed by waterproof nylon cloth processing and fabricating.
Upper table surface (1) of the present invention, circle support (2), interior arm support (3), boom (4), following table (5), gear (6) With rack (7) formed by carbon steel material processing and fabricating.
Embodiment 1:
A kind of mechanical type lifting device with rack-and-pinion climbing structure, its motor (8) are connected with gear (6), tooth Wheel (6) is meshed with rack (7) and be connected, justifies and supports (2) to be arranged on upper table surface (1) bottom, interior arm support (3) and boom (4) Upper end fulcrum is arranged on upper table surface (1), and the upper strong point of boom (4) is fixed on upper table surface (1) bottom by bearing block, only It can rotate, the strong point can roll on upper table surface (1) guide rail on interior arm support (3).Interior arm support (3) and the lower end of boom (4) Fulcrum is arranged on following table (5), and the strong point rolls on following table (5) guide rail under boom (4), is supported under interior arm support (3) Point is fixed on following table (5) by bearing block and can only rotated.Reed organ type dust-proof cover (9) is arranged on upper table surface (1) and following table (5) between.When lowering or hoisting gear works, motor (8) band moving gear (6) operating, gear (6) band carry-over bar (7) is run up and down, rack (7) top is withstood in the circle support (2) of upper table surface (1), when rack (7) is run up, drives circle support (2) to run up, on Table top (1) rises, so as to realize that lowering or hoisting gear steadily rises;When rack (7) is run downwards, upper table surface (1) is made in own wt With lower uniform descent, so as to realize the decline of lowering or hoisting gear.Gear (6) is rotated, then lowering or hoisting gear is run, and gear (6) stops turning Move, then lowering or hoisting gear remains stationary.
