Description

An electrode holder clamping device

technical field

The utility model relates to the technical field of electrode holders, in particular to an electrode holder clamping device.

Background technique

The existing clamping device for the electrode holder of the brown corundum smelting furnace adopts a cylinder spring type device, as shown in FIG. 12 The front end is provided with a spring-type air cylinder '13, the piston of the spring-type air cylinder '13 is connected with the adjustment screw '14, the adjustment screw '14 is movably connected with the tension lever' 15, and one side of the tension lever' 15 is provided With the electrode '16, when the above device is in use, the spring will experience mechanical fatigue, resulting in a decrease in spring tension, reducing the clamping force on the electrode, and prone to the phenomenon of electrode sliding and arcing. At the same time, the spring-type cylinder adopts The screw jack operates in the reverse direction. When replacing the electrode, the operation time is longer. The average time for each replacement of the electrode elastic jack is about 10 minutes, which is a long time, which makes the heat loss of the smelting furnace larger.

Utility model content

The technical problem to be solved by the utility model is an electrode holder clamping device which enhances the clamping force of the electrode and reduces the operation time of replacing the electrode.

In order to solve the above-mentioned technical problems, the scheme of the present utility model is:

An electrode holder clamping device comprises a frame body and a push rod device arranged on the frame body, the front end of the push rod device is provided with a fixing block, and a pin shaft on the fixing block is connected with a force bearing rod, One end of the force-receiving support rod close to the top rod of the push rod device is hook-shaped, and the other end is movably connected with an adjustment screw, and an elastic screw is movably connected to the adjustment screw, and the elastic screw is away from one end of the adjustment screw The pin shaft is connected on the frame body, and the elastic screw rod extends out of a section of the pin shaft connection, and the extended section can be in contact with the top block that bears against the electrode.

Preferably, the push rod device is a jack.

Preferably, the movable connections are all pin connections.

Compared with the prior art, the beneficial effects of the present utility model are:

Since the utility model cancels the spring-type air cylinder, the time for electrode replacement is significantly reduced, and the operating time of the jack is reduced from the original 10 minutes each time to 5 minutes each time, which improves the work efficiency and reduces the smelting furnace time. At the same time, the utility model makes the end of the force-bearing support rod close to the jack's top rod into a hook shape, and the jack's top rod is directly stressed on the hook shape of the force-bearing support rod, so that the The positive pressure of the jack acts directly on the motor, so that the phenomenon of electrode slippage and arcing is significantly reduced.

Detailed ways

The specific embodiments of the present utility model will be further described below with reference to the accompanying drawings. It should be noted here that the description of these embodiments is used to help the understanding of the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as there is no conflict with each other.

Please refer to FIGS. 2-3 , an electrode holder clamping device of the present invention includes a frame body 1 and a push rod device 2 arranged on the frame body 1 , and the front end of the push rod device 2 is provided with a fixing block 7. A force bearing rod 3 is connected to the pin on the fixed block 7. One end of the force bearing rod 3 close to the ejector rod of the push rod device 2 is hook-shaped, and the other end is movably connected with an adjusting screw 4, so The adjusting screw 4 is movably connected with an elastic screw 5, and one end of the elastic screw 5 away from the adjusting screw 4 is connected to the frame body 1. The outgoing section can be in contact with the top block that bears against the electrode 6 .

In order to make its thrust sufficient, the push rod device 2 is a jack.

In order to realize the movement between the rods of the present invention, the movable connections are all pin connections.

Specifically, the working principle of the present utility model is as follows: through the push rod of the push rod device (ie the jack) on the frame body, the force-bearing support rod connected with the pin shaft on the fixed block is pushed to the front end, that is, the hook-shaped support rod is pushed to the front end. Then, through this force, the adjustment screw connected with the force-bearing support rod moves to the left, and the elastic screw hinged with the adjustment screw is pulled. Since the elastic screw pin is connected to the frame body, the lever is used The principle is that it will be affected by the force of the adjustment screw to the left, and the elastic screw will extend out of the pin shaft connection for a section, so that the extended section can be in contact with the top block against the electrode, so as to achieve the tightness of the electrode. Purpose.

The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principles and spirit of the present invention, various changes, modifications, substitutions and alterations can be made to these embodiments, which still fall within the protection scope of the present invention.
