Abstract

The utility model discloses an automatic compaction-type heat treatment furnace door lifting device which comprises upright columns which are arranged opposite to each other, and beams which stretch across and are fixed between upper ends of the upright columns. A furnace door is located between the upright columns. A lifting reducer is fixed on the beams and drives the furnace door to go up and down through chain transmission. Lifting guide rails are arranged on the upright columns. An upper guide wheel and a lower guide wheel are respectively arranged at the upper end and the lower end of each side of the furnace door and contact with the lifting guide rails in rolling fit mode. The lifting guide rails are provided with compaction panels which form 30-degree compaction angles with the lower guide wheels when the furnace door rises to a certain position. According to the automatic compaction-type heat treatment furnace door lifting device, when the furnace door ascends or descends to a certain position along the lifting guide rails, by aid of the functions of the compaction angles which are formed by the compaction panels on the lifting guide rails and the lower guide wheels, a sealing effect of the furnace door at closing time is effectively insured, meanwhile, automatic leaving of a furnace door panel from the furnace door at opening time is ensured so that a furnace bricking body can not be abraded and damaged. Compared with an oil cylinder, an air cylinder or other compaction mechanisms, the automatic compaction-type heat treatment furnace door lifting device saves energy resources and reduces cost.

Description

Automatic compression type heat treatment fire door lowering or hoisting gear

Technical field

The utility model relates to a kind of automatic compression type lowering or hoisting gear that is used for large-scale car-type or cell-type heat treatment fire door.

Background technology

The lowering or hoisting gear of traditional large-scale car-type or cell-type heat treatment fire door, its hold-down mechanism generally use oil cylinder or cylinder or motor drive mechanism to apply external force and control, and need the supporting corresponding external enwergy that provides; Cause structure comparatively complicated, and when external enwergy changes, not enough like oil pressure or air pressure; Make hold-down mechanism produce sealing easily and loosen phenomenon; Bring influence to processing safety, supporting external enwergy has also improved energy resource consumption simultaneously, is unfavorable for saving energy and reduce the cost.

The utility model content

The technical problem that the utility model will solve is: overcome the deficiency in the prior art, provide a kind of compress effect better, dependable performance and the automatic compression type heat treatment fire door lowering or hoisting gear that helps saving energy and reduce the cost,

The utility model solves the technical scheme that its technical problem adopted: a kind of automatic compression type heat treatment fire door lowering or hoisting gear; Comprise the column that is oppositely arranged, across the crossbeam that is fixed between the column upper end; Said fire door is between column; Be fixed with lifting decelerator on the described crossbeam, lifting decelerator drives fire door through the chain transmission and goes up and down, and described column is provided with riser guide; The upper and lower side of fire door both sides is respectively equipped with the riser guide rolling and cooperates upper block, the lower tumbler that contacts, and has on the riser guide after the fire door rising puts in place to become 30 degree to compress the panel at angle with said lower tumbler.

Further, described lifting decelerator is the twin-output shaft type from translator, and chaindriven drive sprocket is installed on the output shaft of lifting decelerator body both sides.

The counterweight of balance fire door when being connected with in the described chain transmission.

Be fixed with the guardrail of easy access and installation on the described crossbeam.

The beneficial effect of the utility model is: the utility model is after fire door goes up and down to put in place along riser guide; Compress panel and lower tumbler through being located on the riser guide form the effect that compresses the angle, have guaranteed the sealing effectiveness of fire door when closing effectively, have guaranteed that fire door can throw off the fire door panel automatically simultaneously again in opening process; Can frictionally damage stove masonry; Than compressing mechanism with oil cylinder or cylinder etc., energy savings reduces cost.

The specific embodiment

Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of automatic compression type heat treatment fire door lowering or hoisting gear as shown in Figure 1; Comprise the column 1 that is oppositely arranged, across the crossbeam 2 that is fixed between column 1 upper end; The fire door 3 of heat-treatment furnace is between column 1, and column 1, crossbeam 2 all adopt the moulding of heavy channel-section steel assembly welding, is fixed with lifting decelerator 4 on the described crossbeam 2; Lifting decelerator 4 drives fire door 3 through chain transmission 5 and goes up and down; Described lifting decelerator 4 is the twin-output shaft type from translator, adopts the helical speed reduction gear structure, realizes the rate conversion in the lifting process through frequency converter.The drive sprocket of chain transmission 5 is installed on the output shaft of lifting decelerator 4 body both sides; Chain transmission 5 lower ends are connected with fire door 3, simultaneously, are installed in the rear of the drive sprocket on lifting decelerator 4 output shafts; Be provided with said drive sprocket be in transmission connection by movable sprocket; Chain transmission 5 used roller chain drives connect drive sprocket and by movable sprocket, said roller chain front end is connected with fire door 3, play the counterweight 10 of balanced action when the rear end of roller chain then is connected with.

Described column 1 is provided with riser guide 6; The upper and lower side of fire door 3 both sides is respectively equipped with to roll with riser guide 6 and cooperates upper block 7, the lower tumbler 8 that contact, have on the riser guide 6 fire door 3 rise put in place back and said lower tumbler spend for 8 one-tenth 30 compress the angle compress panel 9, like this; After fire door 3 operations put in place; Both guaranteed the sealing effectiveness of fire door 3 when closing, guaranteed again simultaneously that fire door 3 can throw off the fire door panel automatically in opening process, can frictionally damage stove masonry.

For the convenience of overhauling at ordinary times and installing, be fixed with guardrail 11 on the crossbeam 2, and corresponding staircase convenient for maintaining personnel guardrail 11 up and down is set.

The utility model is simple in structure, accurate positioning, dependable performance operates steadily, the lifting height of fire door satisfies the operation requirement, compress effective, energy savings.

Above-mentioned embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
