Technical Field

The invention relates to a clamping tool, in particular to a clamping tool for replacing a high-temperature crucible in a casting production line.

Background

In the metal casting production process, a heat-insulating high-temperature crucible used on a pouring production line is an indispensable tool, but the crucible has limited service life and needs to be replaced when the service life is expired. The molten metal is directly stored in the crucible and is in a high-temperature state for a long time. In the normal production process, once a crucible (arranged in a furnace platform) is damaged and needs to be replaced, the crucible needs to be replaced after being cooled to room temperature, the crucible has a large volume and can be replaced only by adopting a suspension mode, the operation is time-consuming and labor-consuming, and the production rhythm is seriously influenced; if the crucible is hung by using a rope, the crucible is high in temperature, so that the risk of rope breakage and injury of a person by the crucible is high.

Disclosure of Invention

The invention aims to overcome the technical defects and provide a convenient high-temperature crucible clamping tool which can be used for conveniently and quickly replacing a crucible and changing the conventional crucible by hanging a rope.

The purpose of the invention is realized by the following technical scheme: frock is got to portable high temperature crucible clamp, including rings, jib, base slider is equipped with on the jib, is equipped with the slider connecting rod under this slider the cushion is equipped with through the base connecting rod on the base, the slider connecting rod meets with the base connecting rod.

The slider connecting rod is installed below the slider through a connecting block, and the outer surface of the cushion block is provided with reticular patterns. And the slide block is provided with a hanging buckle. The cushion block is made of copper.

After the crucible lifting device is adopted, the sliding block moves downwards, the cushion block is firmly pressed on the inner wall of the crucible (like an umbrella-shaped opening) under the tension action of the sliding block connecting rod and the base connecting rod, and the high-temperature crucible is quickly and conveniently clamped by the hoisting ring controlled by the crane, so that the crucible lifting device is convenient and easy to replace, the potential safety hazard caused by directly hoisting the crucible by using a rope is eliminated, and the operation safety is also guaranteed.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic structural diagram of the portable high-temperature crucible clamping tool.

Detailed Description

Referring to fig. 1, the portable high-temperature crucible clamping tool comprises a hanging ring 1, a hanging rod 2 and a base 11 (the hanging ring 1 is arranged at the upper end of the hanging rod 2, the base 11 is arranged at the lower end of the hanging rod 2), a sliding block 4 is arranged on the hanging rod 2 (in the middle), a plurality of sliding block connecting rods 6 (downwards) are arranged below the sliding block 4, a cushion block 7 (and a supporting plate 8) are arranged on the base 11 through a base connecting rod 10, the cushion block 7 and the supporting plate 8 can be combined into a whole and upwards, and the sliding block connecting rods 6 are connected with the base connecting rod 10 (through an intermediate connecting piece 9).

The number of the slide block connecting rods 6, the number of the middle connecting pieces 9, the number of the base connecting rods 10 and the number of the cushion blocks 7 (and the number of the supporting plates 8) are corresponding. The slide block connecting rod 6 is arranged below the slide block 4 through a connecting block 5, and the outer surface (the contact part with the clamped crucible inner wall) of the cushion block 7 is provided with reticular patterns 12. The slider 4 is provided with a suspension clasp 3 (a plurality of pieces). The cushion block 7 is made of copper. The method comprises the following operation steps: the first step is as follows: a steel wire rope is tied on the suspension buckle 3, and the position of the sliding block 4 is adjusted by pulling the steel wire rope upwards or downwards according to the diameter of an on-site crucible (positioned in a furnace platform), so that the angles of the base connecting rod 10 and the sliding block connecting rod 6 can also rotate along with the steel wire rope; the second step is that: the angle of the cushion block 7 is adjusted to enable the cushion block to contact the inner wall of the crucible and is supported by the rod head position of the base connecting rod 10 to ensure that the angle of the cushion block is unchanged; the third step: the hook of the travelling crane is hooked on the lifting ring 1, the travelling crane is slightly lifted upwards, the sliding block 4 moves downwards, and due to the tension action of the sliding block connecting rod and the base connecting rod (the sliding block connecting rod moves upwards, and the base connecting rod moves downwards), the cushion block is firmly pressed on the inner wall of the crucible (like an umbrella-shaped opening); the fourth step: and lifting the travelling crane upwards, moving out the crucible after the bottom of the crucible is higher than the furnace platform, and placing the crucible at a specified position. The fifth step: and the steel wire rope is lifted upwards, so that the sliding block moves upwards, the tension of the sliding block connecting rod and the base connecting rod disappears, the pressure of the cushion block disappears (like umbrella-shaped folding), and the clamping tool can be retracted.

The cushion block 7 (made of copper) is mainly characterized in that the copper material is soft, the melting point of copper is high, the damage degree to the inner wall of the crucible is low, and the mesh-shaped patterns on the outer surface of the cushion block are beneficial to increasing the friction force between the cushion block and the inner wall of the crucible. The suspension clasp 3 is mainly characterized in that after the suspension clasp is added, a steel wire rope is installed on the suspension clasp, the sliding block can move upwards or downwards more conveniently, the sliding block has a certain size, and operation is not convenient without the help of tools.
