Abstract
The utility model discloses a kind of tedge manhole cover headstock gears, including being located at manhole cover, shaft one, shaft two, shaft three, pull rod one, pull rod two, weight linear meter and hydraulic system at the top of tedge, the manhole cover is connect by shaft one with one upper end of pull rod, one lower end of pull rod is fixedly installed weight linear meter, one lower end of pull rod connects hydraulic system by shaft three by two connecting rod of shaft, two upper end, two lower end of pull rod；Spring is provided between two top of pull rod and weight linear meter.The present apparatus it is open and close can conveniently to carry out opening water seal in the case where tedge beats high pressure.
Description
Technical field
The utility model relates to a kind of tedge manhole cover headstock gears, belong to coking production technical field.
Background technique
Tedge is a kind of mounted in oven top of coke oven, to export the coke oven auxiliary device of raw gas in carbonization chamber.Tedge
It is made of cylinder, bridge tube and turnover panel seat.Rising tube cylinder is cast iron or the cylinder with welded steel plate, liner clay brick;Also have
Be made with collet or helically tubular structure, water flowing or organic heat-carrying agent in collet or helix tube, to recycle raw coke oven gas
Sensible heat.Bridge tube top is equipped with manhole cover, escapes pollution atmosphere to prevent raw gas.The turning of bridge tube is equipped with ammonia spray nozzle, to
Hot ammonium hydroxide is sprayed into, by means of ammonia evaporative cooling raw gas.
For tedge manhole cover in the processing of coking raw coke oven gas, manhole cover needs artificial opening and closing, and large labor intensity is dangerous.It is real
After the opening and closing of row automation control manhole cover, a large amount of manual labors are saved, but in the case where automation control, due to actual production
The variation of middle raw coke oven gas yield and the variation for rising pipe pressure cause often to occur being difficult asking for closure after tedge beats high pressure
Topic.
Utility model content
The utility model overcomes above-mentioned the deficiencies in the prior art, provides a kind of tedge manhole cover headstock gear, this dress
Setting it is open and close can conveniently to carry out opening water seal in the case where tedge high pressure.
The utility model is implemented with the following technical solutions:
A kind of tedge manhole cover headstock gear, including be located at tedge at the top of manhole cover, shaft one, shaft two, turn
Axis three, pull rod one, pull rod two, weight linear meter and hydraulic system, the manhole cover is connect by shaft one with one upper end of pull rod, described
One lower end of pull rod is fixedly installed weight linear meter, and one lower end of pull rod passes through two connecting rod of shaft, two upper end, the pull rod two
Lower end connects hydraulic system by shaft three；Spring is provided between two top of pull rod and weight linear meter.
The quantity of the spring is one or more.
Angle is 120-170 degree between the pull rod one and weight linear meter.
The hydraulic system can also be electric and pneumatic system.
Two lower end of pull rod also passes through shaft three and connects a hand lever.
Compared with prior art, the utility model has the beneficial effects that
The present apparatus is helped hydraulic system and pull rod to carry out manhole cover opening and closing, is effectively solved by the elastic force of spring
For manhole cover in the case where automation control, tedge is difficult the problem of being closed after beating high pressure, generates very even if rising pipe pressure
Big high pressure, still can effectively closed manhole cover.The present apparatus is additionally provided with a hand lever, in the case where hydraulic system failure,
Opening and closing manhole cover can be carried out with auxiliary hydraulic system.
Detailed description of the invention
Fig. 1 is the schematic diagram that the utility model manhole cover is closed；
Fig. 2 is the schematic diagram that the utility model manhole cover is opened.
In figure: 1 is manhole cover, and 2 be shaft one, and 3 be shaft two, and 4 be shaft three, and 5 be pull rod one, and 6 be pull rod two, and 7 are
Weight linear meter, 8 be hydraulic system, and 9 be spring, and 10 be hand lever.
Specific embodiment
The utility model is described further with attached drawing with reference to embodiments:
Embodiment 1
A kind of tedge manhole cover headstock gear, including be located at tedge at the top of manhole cover 1, shaft 1, shaft 23,
Shaft 34, pull rod 1, pull rod 26, weight linear meter 7 and hydraulic system 8, the manhole cover are connected by shaft one and one upper end of pull rod
It connects, one lower end of pull rod is fixedly installed weight linear meter, and one lower end of pull rod is described by two connecting rod of shaft, two upper end
Two lower end of pull rod connects hydraulic system by shaft three；Spring 9 is provided between two top of pull rod and weight linear meter.
The quantity of the spring 9 is one or more.
Angle is 120-170 degree between the pull rod 1 and weight linear meter 7.
The hydraulic system 8 can also be electric and pneumatic system.
26 lower end of pull rod also passes through shaft 34 and connects a hand lever 10.
In actual use, for hydraulic system by giving 261 downward pulling force of pull rod, pull rod 25 pulls pull rod 1 to open
Manhole cover；For hydraulic system by giving 261 upward thrusts of pull rod, 25 pushing drawing rod 1 of pull rod closes manhole cover.
And the elastic force of spring 9 can help hydraulic system and pull rod to carry out manhole cover opening and closing, effectively solve automatic
In the case where changing control, after tedge beats high pressure, manhole cover is difficult the problem of being closed.Even if tedge generates very big high pressure, still
It so can effectively closed manhole cover.The present apparatus is additionally provided with a hand lever 10, in the case where hydraulic system failure, can assist
Hydraulic system carries out opening and closing manhole cover.
Basic principles, main features, and advantages of the present invention has been shown and described above, retouches
State more specific and detailed, but it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that
For those of ordinary skill in the art, without departing from the concept of the premise utility, several changes can also be made
Shape and improvement, these are all within the protection scope of the present invention.
