Abstract
The utility model provides a furnace lid lifting mechanism for a pit furnace. The furnace lid lifting mechanism comprises a support, a hollow lifting shaft, a speed reducer and a screw rod. The support is installed on the side wall of a furnace body. The top end of the lifting shaft is connected with a furnace lid. A lifting nut is installed at the tail end of the lifting shaft. The speed reducer is installed on the support. The screw rod is installed on the speed reducer. The upper end of the screw rod stretches into the tail end of the lifting shaft and is connected with the lifting nut through a thread. The lifting shaft is connected in two shaft seats in a sleeved mode, wherein the two shaft seats are arranged in a perpendicular mode. The shaft seats are installed on the side wall of the furnace body. The furnace lid lifting mechanism for the pit furnace has the advantages of being simple in structure and safe and convenient to use; the screw rod is additionally arranged at the tail end of the lifting shaft and is used for realizing the lifting operation of the whole furnace lid, and therefore the lifting operation is rapid and convenient; the lifting shaft is shortened, so that invested cost is reduced; the screw rod is easy and convenient to maintain and replace, and the screw rod can be replaced rapidly even if the screw rod is damaged; and the furnace lid lifting mechanism for the pit furnace is high in efficiency and low in cost.
Description
Technical field
The utility model relates to a kind of elevating mechanism, especially a kind of shaft furnace furnace cover lifting mechanism.
Background technology
At present, the folding of shaft furnace bell be by a lifting shaft move up and down to promote bell, as shown in Figure 1, the bottom of lifting shaft is provided with external screw thread, and is installed on the reductor, under the effect of reductor, lifting shaft is whole to move up and down; Its drawback is: lifting shaft is very long, has increased production cost; In a single day external screw thread on it is fragile, and is damaged, then cause whole elevating mechanism to operate, and must change, and the time cycle of replacing is long, the cost height.
Summary of the invention
The utility model is a kind of improvement of making at the deficiency of prior art existence, and it is a kind of simple in structure that purpose provides, and is convenient to the shaft furnace furnace cover lifting mechanism that safeguards and change.
The purpose of this utility model is achieved by the following technical solution: comprise that one is installed in support, the hollow lifting shaft on the sidewall of the furnace body; The top of described lifting shaft is connected with bell, and tail end is provided with a lifting nut; One reductor is installed on the described support; One screw mandrel is installed on the described reductor; The upper end of described screw mandrel stretch into described lifting shaft tail end and with described lifting nut by being threaded.
Described lifting shaft is socketed in the two vertically arranged axle beds; Described axle bed is installed on the described sidewall of the furnace body.
The beneficial effects of the utility model are: it simple in structure, safe and convenient to use, add screw mandrel at the lifting shaft tail end, and utilize screw mandrel to finish the descending operation of whole bell, rapid and convenient; Lifting shaft shortens, and has reduced input cost, the maintenance of screw mandrel and change simple and convenient, even the phenomenon of being damaged also can change fast, the efficient height, cost is low.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, 2, comprise that one is installed in support 1, the hollow lifting shaft 2 on the sidewall of the furnace body 6; The top of described lifting shaft 2 is connected with bell 7, and tail end is provided with a lifting spiral shell 3 mothers; One reductor 4 is installed on the described support 1; One screw mandrel 5 is installed on the described reductor 4; The upper end of described screw mandrel 5 stretch into described lifting shaft 2 tail end and with described lifting nut 3 by being threaded, reductor 4 starts the back and drives screw mandrel 5 rotations, because screw mandrel 5 and lifting nut 3 are by being threaded, in screw mandrel 5 rotations, whole lifting shaft 2 rises under the effect of lifting nut 3 or descends.
Described lifting shaft 2 is socketed in the two vertically arranged axle beds 8; Described axle bed 8 is installed on the described sidewall of the furnace body 6, and two axle beds are welded on sidewall of the furnace body, are arranged vertically between the two, can play guide effect to lifting shaft.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
