Description

Furnace door plate lifting mechanism

Technical Field

The utility model relates to a thermal treatment equipment technical field especially relates to a furnace door plant elevating system.

Background

In the prior art, the heat treatment equipment comprises a heat treatment furnace, the heat treatment furnace is provided with a furnace door opening for carrying parts inwards or outwards, a furnace door plate is arranged at the furnace door opening, the furnace door plate needs to be covered on the furnace door during heating, and phenomena such as smoke leakage and fire generation can be prevented.

To the great stove door plant of size, its mode of opening mostly upwards promotes the stove door plant through equipment such as hoist and opens the stove gate mouth, it also closes the stove gate mouth through the hoist to descend the stove door plant, in the actual opening or closing process, the furnace gate only receives the effect of the drive power that comes from the top, thereby easily around when upwards or the downstream, the edge at left and right sides swing collision stove gate mouth, long-term collision probably leads to the edge at stove gate mouth to knock out the pit, make the leakproofness of stove door plant and stove gate mouth reduce, cause the interior cigarette of running of stove, phenomenons such as fire, both the energy has been wasted, the environment has been polluted again, influence normal use. This problem is urgently to be solved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a furnace door plant elevating system for the furnace door plant switches the furnace gate steadily, improves the sealing performance and the life at furnace door plant and furnace gate mouth.

The utility model discloses a realize through following technical scheme: the utility model provides a furnace door plant elevating system, includes furnace door plant and sharp power device, lies in the left and right sides at the furnace gate mouth on the stove outer covering and is equipped with the slide rail of direction from top to bottom respectively, the furnace door plant with sliding connection between the slide rail, connect on the furnace door plant the movable end of sharp power device, the stiff end of sharp power device articulates in ground through the pivot, the furnace door plant is in close or open under linear power device's the control the furnace gate mouth.

The preferable scheme is that the sliding rail and the furnace door plate are both provided with backward inclination angles matched with the furnace shell, and the axis of the rotating shaft is parallel to the furnace door plate.

Preferably, water pipes for passing cooling water in and out are arranged on two sides of the furnace door plate, and the movable end of the linear power device is welded on the water pipes.

In addition, the preferable scheme is that the linear power device is a hydraulic device and comprises a hydraulic pump and a piston rod, the bottom of the hydraulic pump is hinged to the ground through a rotating shaft, and the piston rod is welded on the furnace door plate.

The beneficial effects are that: compared with the prior art, the utility model enables the furnace door plate to open and close the furnace door stably, improves the sealing performance and the service life of the furnace door plate and the furnace door opening; in addition, set up cooling water piping in the furnace door board, increased the cooling effect of furnace gate, also provide reasonable welding position for linear power device's installation.

Detailed Description

As shown in fig. 1-4, a furnace door plate lifting mechanism comprises a furnace door plate 1 and two hydraulic devices, and is applied to a heat treatment furnace, wherein slide rails 4 in the up-down direction are respectively arranged on the left side and the right side of a furnace door opening 3 on a furnace shell 2 of the heat treatment furnace, the furnace door plate 1 is in sliding connection with the slide rails 4, one side of the left side and the right side of the furnace door plate 1 is provided with a water inlet pipe 6, the other side of the left side and the right side of the furnace door plate 1 is provided with a water outlet pipe 6 for introducing cooling water, and the furnace door plate 1 at the moment becomes a circulative cooling; two hydraulic means, 8 welding of one of them piston rods pass through bracket 9 on the water pipe 6 of intaking, and 8 welding of another piston rod pass through bracket 9 on the water pipe 6 of water, hydraulic means's hydraulic pump 7's bottom articulates in ground (ground is equipped with buried bolt in advance or pre-buried parallels) through pivot 5, perhaps hydraulic means's hydraulic pump 7's bottom articulates on hydraulic pump base 10 through pivot 5, furnace door board 1 is in close or open under hydraulic pump 7's the control furnace door mouth 3. According to the embodiment, the furnace door 1 can be stably opened and closed, so that the sealing performance and the service life of the furnace door 1 and the furnace door opening 3 are improved; in addition, set up cooling water piping in the furnace door board 1, increased the cooling effect of furnace gate, also provide reasonable welding position for hydraulic means's installation.

As shown in fig. 4, the sliding rail 4 and the door panel 1 are both provided with a backward inclination angle C matching with the furnace shell 2, the value range of the angle C is generally 3-15 °, and the axis of the rotating shaft 5 is parallel to the door panel 1, so that the door panel 1 is favorably limited to incline outwards or move in an arc shape, and the opening or closing stability of the door panel 1 is improved.
