Abstract
The utility model discloses a protect screw headstock gear entirely has overcome prior art, and the difficult protection of screw headstock gear screw rod leads to the easy problem of destroying of screw thread. The utility model discloses a contain aircraft nose, frame, screw rod, the top of screw rod and bottom mounting and sealing connection have flexible pillar. Flexible pillar divide into pillar and lower pillar, goes up the pillar and is the transparent wired hose of PVC, and lower pillar is transparent wired hose of PVC or flexible rubber hose. This technique simple structure, the wear -resisting ageing resistance of the transparent wired hose of PVC, big, flexible good, the price low grade characteristics of magnification, it is especially adapted as the protection of headstock gear screw rod. Realize the most genuine full protection (upper and lower protection), make the screw thread be in an enclosure space, prevent that the foreign object from getting into, avoids destruction. The intact protection of screw rod makes that the headstock gear operation is reliable, the trouble is few, longe -lived, and the practical function is showing.
Description
Technical field
This utility model relates to a kind of worm-type open-close machine, particularly relates to a kind of full protection worm-type open-close machine.
Background technology
Worm-type open-close machine is used on the water hole road of various hydraulic engineering, play the middle-size and small-size open/close machinery equipment of one controlling sluice, utilize the lifting of this machine to make its supporting sluice realize opening and closed water hole road, controlling water level, adjust flux effect, it is widely used in the engineerings such as water conservancy and hydropower, urban construction, aquaculture and construction of water conservancy works.
Worm-type open-close machine have structure simple, use rationally, the feature such as low price, easy for installation, A wide selection of colours and designs is widely used in various hydraulic engineering.But worm-type open-close machine also has deficiency in actual use: screw rod protection is bad, and screw thread easily destroys, reduce transmission efficiency and even inefficacy.Therefore screw rod protection is carried out extremely important.Conventional screw headstock gear adopts rigid casing protection, and sleeve pipe is fixed on the gland of head, protects screw rod top, prevents sleet, dust storm, dust etc. from entering; Because rigid casing can not be installed in screw rod bottom, therefore cannot protect, screw thread soaks in water and is more vulnerable to destruction (corrosion in water, Sediment Siltation, contaminants adhere etc.), causes the reduction in headstock gear application life.Rigid casing material adopts carbon steel, stainless steel or glass fiber reinforced plastic.Except not doing except full protection, rigid casing also has following defect: 1. carbon steel, stainless steel sleeve pipe are opaque, cannot observe screw rod and run; Carbon steel, stainless steel casing wt are large, increase body load; Although 2. glass reinforced plastic sleeve is transparent, can observe screw rod and run, it is not wear-resisting easily aging, and fragility is fragile greatly; 3. stainless steel, glass reinforced plastic sleeve price, cost is high; 4. rigid casing setting height(from bottom) is large, and external applied load impact is large, and wind and rain weather body has vibrations more.
Utility model content
The utility model overcomes in prior art, and worm-type open-close machine screw rod not easily protects the problem causing screw thread easily to destroy, and provides the full protection worm-type open-close machine that a kind of structure is simple, easy to use.
Technical solution of the present utility model is, provide a kind of full protection worm-type open-close machine with following structure: containing head, support, screw rod, the top of described screw rod and bottom are fixed and be sealedly connected with flexible pillar.
Described flexible pillar is divided into pillar and lower pillar, and upper pillar is for being PVC transparent wired hose, and lower pillar is PVC transparent wired hose or rubber hose.Described flexible pillar is telescopic bellows, screw rod exceed upper part of head section length and lower than the length of head lower part respectively between the maximum elongation length and minimum compressed length of upper pillar and lower pillar.Described head inside has transmission mechanism to drive load-bearing nut to rotate, and drives screw rod to be elevated and open-close sluice gate.Described transmission mechanism is bevel gear or worm gear, is driven by motor or hand crank.
Compared with prior art, the utility model full protection worm-type open-close machine has the following advantages: PVC transparent wired hose has complete, wear-resisting anti-aging, the feature such as magnification is large, flexible, price is low of the many specifications of kind, very applicable as the protection of headstock gear screw rod.Realize full protection (upper and lower protection) truly, make screw thread be in an enclosure space, prevent foreign object from entering, exempt from destruction.The intact protection of screw rod makes that headstock gear is reliable, fault is few, the life-span is long, and practical function is remarkable.
PVC transparent wired hose has good retractility, with screw action, by observing the retracted position of upper pillar, can run by direct vision screw rod; PVC transparent wired hose adopts Flange joint, fixing, install, dismounting, change easily convenient.Can outdoor installation, be used in windy and dusty environment; Also can be used for the wastewater media that is corrosive.Do not need at some the occasion using the expensive material screw rod of stainless steel, effectively can economize on resources, cut the waste.
Full protection worm-type open-close machine structure is simple, uses rationally, safe and reliable, durable in use, in the engineerings such as municipal and environment-friendly plumbing, pumping plant, electric power, irrigation and water conservancy irrigation, play more and more important effect.It is cheap, practical, good economy performance, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is the working state schematic representation that the utility model full protection worm-type open-close machine opens gate;
Fig. 2 is the working state structure schematic diagram of the utility model full protection worm-type open-close machine closed shutter.
Detailed description of the invention
During accompanying drawing illustrates, label 1 is upper pillar, and 2 is heads, and 3 is supports, and 4 is screw rods, and 5 is lower pillars, and 6 is hand cranks, and 7 is gates.
Below in conjunction with the drawings and specific embodiments, the utility model full protection worm-type open-close machine is described further: as shown in the figure, containing head 2, support 3, screw rod 4 in the present embodiment, the top of described screw rod 4 and bottom are fixed and are sealedly connected with flexible pillar.
Described flexible pillar is divided into pillar 1 and lower pillar 5, and upper pillar 1 is for being PVC transparent wired hose, and lower pillar 5 is PVC transparent wired hose or rubber hose.Described flexible pillar is telescopic bellows, screw rod 4 exceed head 2 upper part length and lower than the length of head 2 lower part respectively between the maximum elongation length and minimum compressed length of upper pillar 1 and lower pillar 5.Described head 2 inside has transmission mechanism to drive load-bearing nut to rotate, and drives screw rod 4 to be elevated and open-close sluice gate 7.Described transmission mechanism is bevel gear or worm gear, is driven by motor or hand crank 6.
