Abstract

The utility model relates to an improvement of the explosion-proof tank structure, in particular to an explosion-proof tank which has a simple structure and can be used in an open-air place. The explosion-proof tank comprises a spherical tank body; wherein, a U-shaped cross beam is arranged between lifting arms sleeved on the guiding shafts of central shafts arranged on both sides of the tank body, and is connected with a tank cover through a connecting plate; and link rods arranged on the shafts of steadiers positioned on the outsides of the lifting arms are connected with the shafts of the push-pull plates of the central shafts. The explosion-proof tank has the following structural characteristics: link rods arranged on the other shafts of the push-pull plates are connected with swing arms arranged on the output shaft of a worm-gear reducer; the worm-gear reducer is connected with an electromotor through a gearbox; and a duplicate gear is arranged between a gear arranged on the shaft of the electromotor and a gear arranged on the input shaft of the worm-gear reducer, and is fixed on the shaft of a handwheel.

Description

A kind of anti-explosion tank

Technical field:

The utility model relates to the improvement of explosion-proof tank structure.

Background technology:

Anti-explosion tank is to be used for the interim tankage that stores and shift explosive, in case explosive in the jar implode, can effectively be defendd the harm of exploding and being caused.

At present, the China Patent No. that has more advanced in the existing anti-explosion tank is the anti-explosion tank of ZL200720193464.4, it is to adopt external cover elevating mechanism, but has following shortcoming: 1, adopt symmetry two cover worm gears, worm mechanism cover to be opened its structure more complicated; 2, because of outside worm gear, worm screw be exposed to, the wind and weather easy-to-rust has influenced the unlatching of cover; The structure of 3, uncapping has adopted universal coupling, and effort operates.

The utility model content:

The utility model is exactly at the problems referred to above, provide a kind of simple in structure, can be suitable for the anti-explosion tank that open-air occasion is used.

For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises spherical tank body, is provided with U type crossbeam between the lifting arm outside the axis of guide of tank body both sides central shaft, and U type crossbeam links to each other with cover by connecting plate; Axle on the draw back plate on the concentricity axle of connecting rod on the axle of lifting arm outer support links to each other, and another on its structural feature draw back plate gone up connecting rod and linked to each other with the output shaft top link of worm gear reducer, and worm gear reducer links to each other with motor by gearbox; Gear on the motor shaft is provided with double linked wheel between cogging with the power shaft of worm gear reducer, and double linked wheel is fixed on the hand axle of taking turns.

The beneficial effects of the utility model:

1, simple in structure:

The utility model adopts once cover worm gear, worm mechanism and can open cover, and its structure is more simple in structure than existing;

2, being suitable for open-air occasion uses:

Worm gear of the present utility model, worm screw all are arranged in the worm gear reducer; Therefore, worm gear, worm screw directly do not contact with rainwater, are difficult for corrosion, compare with existing structure and are more suitable for open-air occasion use;

3, rapid operation:

The utility model adopts the connecting rod transmission, and perturbed force is few, therefore, uses laborsaving.

The specific embodiment:

The utility model comprises spherical tank body 21, is provided with U type crossbeam 18 between the lifting arm 16 outside the axis of guide 9 of tank body 21 both sides central shafts 20, and U type crossbeam 18 links to each other with cover 19 by connecting plate 17; Axle 11 on the draw back plate 10 on the connecting rod 13 concentricity axles 20 on the axle 14 of lifting arm 16 outer supports 15 links to each other, on the draw back plate 10 another on 12 connecting rod 8 link to each other with output shaft 2 top links 7 of worm gear reducer 1, worm gear reducer 1 links to each other with motor 6 by gearbox 5; Gear 26 on 6 27 in the motor cogs with the power shaft 23 of worm gear reducer 1 and is provided with double linked wheel 25 between 24, and double linked wheel 25 is fixed in hand the wheel on 4 the axle 28.

Shifting block 31 between the double linked wheel 25 be arranged on eccentric wheel 29 the axle 30 on, eccentric wheel 29 be arranged on gearbox 5 shift handle 3 the axle 30 on.

Below in conjunction with a description of drawings course of action of the present utility model:

When opening cover 19: motor 6 rotates, drive draw back plate 10 and rotate by gearbox 5, worm gear reducer 1 output shaft 2 top links 7, connecting rod 8 around central shaft 20, the lifting arm 16 of the axle 14 on the axle 11 pulling bearings 15 on the draw back plate 10 slides to tank body 21 center positions along the axis of guide 9, slide follow-up continuous rotate around central shaft 20 that put in place, the connecting plate 17 of lifting arm 16 by U type crossbeam 18 drives covers 19 and moves in tank body 21 and overturn.

When closing cover 19: motor 6 backward rotation, above-mentioned member inverted running, then cover 19 restores to the original state, and covers till the tank body 21.

When desiring hand switch cover 19, shift handle 3 is rotated, a gear that makes double linked wheel 25 by shifting block 31 cogs with the power shaft 23 of

worm gear reducer

1 and 24 links to each other, and motor 6 gears 26 conducting paths disconnect, and rotates handly to take turns 4 and just can pass through cover such as switch such as realization such as worm gear reducer 1 member such as grade 19.
