PURPOSE:To enable a compact device to more a measuring lance by a required distance by means of connecting two movable shafts which are alternatively reciprocated at the side of the measuring lance in a horizontal sonde. CONSTITUTION:Two movable shafts 8a, 8b between which the measuring lance 1 in a horizontal sonde is put, are arranged in parallel and supported reciprocatably by the bearing 10 fixed to the stationary portion of the sonde device. A pear of chacks 13a, 13b are fixed to the measuring lance by way of a support 14, thereby holding the movable shaft 8a, 8b. These movable shafts 8a and 8b are caused to reciprocate continuously such that when one shaft is moved forwardly, the other shaft is moved back. In this period, the measuring lance 1 is inserted into a shaft-furnace 2 or moved back and pulled out from the furnace by holding the measuring lance 1 alternatively by the chack 13a or 13b.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horizontal sonde for measuring temperature and pressure in a shaft furnace such as a blast furnace or for sampling gas samples, and particularly to a device for driving the lance thereof.

Conventionally, as a device for driving the measuring lance of this type of horizontal sonde, a hydraulic cylinder is placed behind the measuring lance, and the rear end of the measuring lance is connected to the tip of the rod of the hydraulic cylinder. The measuring lance is inserted into the shaft furnace by moving the opening and closing parts forward and backward.
However, in the conventional device described above, the total length of the device is the sum of the length of the measuring lance, the length of the hydraulic cylinder, and the length of the stroke of the hydraulic cylinder. As a result, the device becomes long and large-scale, and has a considerable weight.1 This not only increases manufacturing costs but also limits the installation space.

The object of the present invention is to provide a drive device for a horizontal sonde that can effectively solve the above problems.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic diagram showing an embodiment of the present invention,
The measuring lance 1 is arranged so that it can be inserted into and removed from the shaft furnace 2 by penetrating the iron skin 3 of the shaft furnace 2 and the refractory material 4 affixed to its inner surface. The lance 1 includes a seal pulp 5 attached to the outer surface of the iron skin 3.
This sealing pulp 5 is sealed by a sealing device 7 attached via a pepper 6.

On the side of the measuring lance 1, there are two
A book movement shaft 8am8b is arranged parallel to the measuring lance 1. These moving shafts 8&, 8b are supported so as to reciprocate in a direction parallel to the moving direction of the measuring lance 1 by a bearing 10 attached to a fixed part 9 such as an arm of the sonde device. Moving shaft 7)
The rear end of the 8N% 8b is connected to a rod 12&m12b of a hydraulic cylinder 11&m111) operated by drive means, such as hydraulic or pneumatic pressure. Note that these fluid pressure cylinders 111% 11b perform these operations II
The movable shafts 7) are operated in opposite directions by valves (not shown) installed in a hydraulic or air circuit (not shown) controlled by I.
8 a z 8 b is designed so that when one moves forward, the other moves backward.

Furthermore, the measuring lance 1 includes one movable shaft 7) of 8 m;
A pair of chucks 13&%L5tl for gripping 8b
is attached via a mounting base 14. These chucks t3a%13b are configured so that when one is in the ON state and grips one of the moving shafts 8&, 8b, the other is in the OFF state. It is possible to adopt a structure that operates with hydraulic or pneumatic pressure, or a structure that operates electrically, but if a structure that operates with hydraulic or pneumatic pressure is adopted, the chuck 13 &
One of the terminals 415b is turned ON when fluid pressure is applied, and the other is set to 0A! when fluid pressure is applied. If it becomes, chuck 15&%13 with 11 piping
The 0N-OFF control of b can be performed, and even if the pressure decreases due to a failure in the hydraulic system or the like, one of the chucks remains ON, so the measuring lance 1 can be held securely. 〇Next, the operation of moving the measuring lance 1 forward and backward by the above-mentioned drive device will be explained. First, the moving shaft 8a
18b by the fluid pressure cylinder 11 & m11b,
Continuously reciprocate so that when one moves forward, the other moves backward. When the measuring lance 1 is moved forward, that is, when it is moved to the right in FIG.
At the same time, the chuck 13b or 13a provided corresponding to the moving shaft 8b or 8a that is moving backward in the direction away from the shaft furnace 2 is turned off. That is, while the moving shafts 7) 8aN8b are moving forward, the chucks 13&, 131
), the measuring lance 1 moves onto the moving shaft 8.
Move forward with & or 8b and insert into the shaft furnace 2!
-2, the movable shaft 7) 8& or 8b is gripped by the shaft 13& or 131) and is provided corresponding to the movable shaft 8b or 81 which is moving forward toward the shaft furnace 2; Turn off the controller, i3b or 13&. That is, the moving shafts 13 & 11311 are moved only while the moving shafts 7) 8m and 8b are moving backward.
When the measuring lance 1 is gripped alternately with the moving shaft 8I,
It moves forward together with L or 8b and is extracted from the shaft furnace 2. The above operations can be summarized in one way as shown in Table 11, Table 2. Table 1, , 11.
Therefore, by alternately gripping the shaft 41, the leg 52, 7)81L%81) with the handle 13&%13b, the measuring lance 1 can be moved forward or backward continuously, so the measuring lance 1 can be moved a required distance without increasing the movement stroke of the moving shafts sa, 8b, that is, the stroke length of the hydraulic cylinder 111Lm1M. In addition, in the above-mentioned device, each moving shaft 7)8&%81) is stopped by stopping each fluid pressure cylinder 11a%111), and in this state, if any chuck 13a%131) is turned on, For example, the measuring lance 1 can be stopped at a predetermined position.

In the above embodiment, two moving shafts (8as8b) are provided, but the present invention is not limited to the above embodiment, and may be constructed with three or more moving shafts or two or more pairs of moving shafts. Often, when 13 or more moving shafts or 2 or more pairs of moving shafts are provided, these moving shafts are sequentially moved back and forth after a certain period of time, and the moving shafts are sequentially gripped and released by a chuck attached to a measuring lance. It may be configured as follows. Further, instead of being attached to the measuring lance 1, the chuck may be attached to a moving shaft, and the measuring lance may be gripped by the chuck. In this case, in order to prevent the chucks from interfering with each other as the moving shaft moves back and forth, it is preferable to provide the chucks at positions offset from each other in the direction of movement of the measuring lance. Further, the driving means for moving the moving shaft 7) back and forth may be provided at the end of the moving shaft 7) closer to the shaft furnace, or may be provided at both ends of the moving shaft to apply a tensile force to the moving shaft. It is also possible to make it reciprocate by adding a . If the movable shaft is configured to be reciprocated by applying a tensile force, there is no risk of the movable shaft buckling.
This has the advantage that the moving shaft can be made thinner. Furthermore, the drive device of the present invention can be used not only as a sonde device for a shaft furnace but also as a drive device for a sampler or the like that is inserted through a tuyere to collect gas or solids in the furnace.

As is clear from the above description, according to the drive device of the present invention, at least two moving shafts are provided on the sides of the measuring lance and are moved back and forth alternately in a direction parallel to the moving direction of the measuring lance. Since any one of the moving shafts 7) and the measuring lance are sequentially and selectively connected via the chuck, even if the forward movement or backward movement force i of each moving shaft is intermittent, the measuring lance can be connected continuously. At the same time, the measuring lance can be moved the required distance even with a short stroke of the moving shaft.
Therefore, according to the drive device of the present invention, in combination with the fact that the moving shaft is disposed on the side of the measuring lance in parallel with the measuring lance, the overall length of the device can be shortened and the device can be made compact as a whole. effective.
