FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic structural view of the locking block of the present invention.
In the figure: 1. an electric hoist; 2. a furnace door; 3. a gantry steel structure; 4. a pulley; 5. a locking block; 6. locking the door slide; 7. a guide section; 8. a lower sliding section; 9. and (4) locking the section.
Detailed Description
The present invention will be further explained below.
Example 1: referring to fig. 1 and 2, a furnace door locking device for a preheating furnace, includes furnace door 2 and portal steel structure 3, be equipped with on portal steel structure 3 and lift by crane the electric block 1 of operation to furnace door 2, carry out lifting by crane of furnace door 2 through electric block 1 and realize opening and close of furnace door 2, the side of furnace door 2 is equipped with pulley 4, the portal is just structural to be equipped with latch segment 5, set up the locking door slide 6 that is convenient for pulley 4 gliding and locking on latch segment 5, pulley 4 and the locking door slide 6 sliding connection on the latch segment 5 utilize the cooperation of pulley 4 and locking door slide 6, when furnace door 2 was put down to electric block 1, utilize the dead weight of furnace door 2, realize the locking of furnace door 2.
The locking door slide 6 is divided into three sections from top to bottom, and the locking section 9 that is guide section 7, gliding section 8 and slope in proper order, guide section 7 is the opening form for in guide pulley 4 gets into locking door slide 6, avoid pulley 4 and 5 edges of latch segment to collide with and cause the damage, gliding section 8 is vertical to be set up, and gliding section 8 is used for the vertical lift of furnace gate 2 to the steady decline of furnace gate 2 is to locking section 9, 9 lower extremes of locking section incline towards the furnace inboard, and when pulley 4 got into locking section 9 back looks furnace side slope slip, it is steady near to furnace to drive furnace gate 2 in the process of descending, finally realizes closing and locking of furnace, and the gradient of locking section 9 specifically is decided according to the on-the-spot furnace gate 2 circumstances.
The pulley 4 has two middle upper portions and middle lower portions which are positioned on the side face of the furnace door 2, and the locking block 5 has two middle portions and two lower portions which are respectively positioned on the portal steel structure 3. The left side and the right side of the furnace door 2 are provided with four groups of pulleys 4, and the door frame steel structure is provided with a locking block 5 matched with the door frame steel structure. Two sets of pulleys 4 and the cooperation of latch segment 5 are adopted respectively to the furnace gate 2 left and right sides, and aim at makes furnace gate 2 promote or descend in-process even running, causes furnace gate 2 to rock in avoiding electric block 1 course of operation, and simultaneously behind furnace gate 2 auto-lock, both ends all hug closely in the furnace chamber mouth about enabling furnace gate 2.
The working principle is as follows: when the furnace door 2 is opened, the electric hoist 1 lifts the furnace door 2, and the pulley 4 loosens the furnace door 2 along the inclined plane of the locking door slideway 6; when the oven door 2 is closed, the pulley 4 closes and locks the oven door 2 along the inclined plane of the locking door slideway 6, and the locking force is provided by the self weight of the oven door 2.
