Abstract

The solution relates to a mechanism for alternating movement of the elevator in devices with extreme temperatures, for example in cycling chambers. The mechanism consists of four guides fixed to the elevator, which are slidably inserted on guide rods. The elevator is connected by means of a holder with locking pulleys to one end of the rope mounted on the guide pulleys and passing through the locking mechanism. The other end of the rope is connected by means of a holder to the piston rod of the control cylinder. The end stops of the piston rod of the control cylinder are fixed on the control cylinder [1].

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for firing a lift in devices by sextreme temperatures, for example, in cycling chambers where a maximum temperature of up to 200 [deg.] C. is reached in a warm section, a maximum of < In the presently known apparatus for moving the elevator in a conventional manner, it is solved by means of special pneumatic devices located below the cold or hot section. The disadvantages of these devices are that the mechanisms located under the cold section must be constructed of materials that resist the temperature and the guiding parts coming out of the cold section must be churned to thaw the ice and teambol allows the lift to move. Mechanisms located above the warm section must be constructed of materials that resist long-term tempering performance. It is also a disadvantage that the mechanisms located above the hot section increase the height of the cycling chamber, with difficulty in accessibility and advantages of construction and construction materials.

The above-mentioned drawbacks are alleviated by a technical problem. a mechanism for moving the elevator in an apparatus at extreme temperatures, the principle of which is to comprise four conduits mounted on the elevator which are slidable on the guide rods. The elevator is connected to the one end of the rope mounted on the guide rollers by a locking roller holder and by a passing locking mechanism. The second rope end is connected by a handle to the piston rod of the actuating cylinder. On the control cylinder, the stops of the end position of the piston rod of the control cylinder are fixed. An advantage of the elevator intermittent mechanism in the extreme temperature apparatuses of the invention is that the mechanism is located outside the tempering space so that it can be constructed of conventional construction materials. The tilt mechanism reduces the height of the cycling chamber and seals the tempering space. It is also advantageous that the elevator, which is guided through the entire length of the stroke, prevents it from tilting when the test sample is unevenly loaded.

The mechanism for alternately moving the extrusion in extreme temperature devices is exemplified in the accompanying drawings, wherein in Fig. 1 it is shown in a drawing, in Fig. 2 the section of the A-A in Fig. 1 and in Fig. 3 is shown in B-B of FIG. 1 in an enlarged scale.

The mechanism for alternately moving the extrusion in the extreme temperature devices is formed by four conduits 7 mounted on the elevator 3. The conduits 7 are slidable on the guiding rods 6. The elevator 3 is connected to one end of the cable 2 by means of a locking catch 9. On the friction 11, a locking mechanism 5 is mounted over the elevator 3, consisting of a pivot lock 10 connected to the pneumatic cylinder 12. The other end of the rope 2 is connected by a retainer 16 of the locked nut. A guide rod 19 is mounted on the control rod 1. The adjusting stops 14,15 are mounted on the actuating cylinder 1. In the space between the cold section 21a and the hot section 20, the bed 23 of the elevator 3 is formed in the end position of the hot section 20 and the bed 22 in the end position of the cold section 21.

The function of the elevator moving mechanism in extreme temperature devices is as follows: Lift 3 moves from the warm section 20 to the opposite section 21a. In the starting position, the thrust 3 is moved to the warm section 20 by the movement of the piston rod of the control cylinder 1 by the deceleration. The stop 18 on the piston rod of the actuator 1 is seated on the adjustable stop 14. The pivot latch 10 of the locking mechanism 5 is rotated by the pneumatic cylinder 12 to the locking position, i.e. the under-locking pulley 9. In the end position, the elevator 3 is moved into the seat 22 and thereby seal each other section. *

When moving in the elevator 3 to the cold section 21, the pneumatic cylinder 12 rotates the pivot latch 10 out of the path of the stacks 9. Thereafter, the piston of the control cylinder 1 is moved upwards with the bracket X6 and la-2. The elevator 3 starts to move down its own weight. The elevator 3 is guided along the guide rods 6 and moves until it is seated in the seat 23 and seals 20, 21 each other. The stop 15 prevents the lift from moving further downwards.
