Detailed Description

The first embodiment.

The embodiment provides a sizing cover with vacuum tube 2, and this sizing cover improves on original structural scheme and reachs, and is too concentrated and quantity less to 4 water jets of metal water pipe 5 in the original scheme, and unable even sprays water to the metalwork and cools off, and a plurality of problems of uncontrollable cooling water spraying position provide this embodiment.

The working method of the embodiment is as follows: 1. when the metal piece enters the sheet-shaped hollow sleeve through the upper flange plate 1, conveying cooling water into the metal water pipe 4; 2. at the moment, the outer sleeve 6 is in an initial state and is tightly close to the lower flange 3, the water permeable window 7 is concentrated at one end of the metal water pipe 4, so that the water spray opening 5 positioned below the water permeable window 7 is in an open state, and cooling water is sprayed out from the water spray opening 5 in the open state; 3. after one end of spraying time, starting the hydraulic telescopic mechanism 15 to drive the connecting rod 9 to move outwards towards the upper flange plate 1, driving the outer sleeve 6 to slide together by the connecting rod 9, changing the position of the water permeable window 7 of the outer sleeve 6, enabling the water spraying ports 5 which are originally in the opening state to be still in the opening state due to the movement of the outer sleeve 6, enabling the water spraying ports 5 which are originally in the closing state to be in the opening state at the moment, and spraying water outwards, wherein all the water spraying ports 5 spray water outwards simultaneously to enable the metal piece to be cooled more uniformly; 4. and (3) after the water spraying port 5 in the opening state sprays water for a period of time, repeating the step (3) until the cooling is finished.

In order to keep the degree of freedom, the outer sleeve 6 is not directly fixed on the lower flange 3, one end of the outer sleeve is wrapped with the waterproof cloth 8, the waterproof cloth 8 is fixedly connected on the lower flange 3, the joints of the waterproof cloth 8 are required to be subjected to sealing and waterproof treatment, so that cooling water of the metal water pipe 4 cannot run off through the outer sleeve 6, and the cooling water can be completely sprayed out of the metal water pipe 4, wherein the waterproof cloth 8 is waterproof firstly, and high temperature resistance is required due to the high temperature of the working environment of the waterproof cloth 8, and any feasible existing solution can be adopted, such as glass fiber waterproof flame-retardant cloth and even geotextile.

In order to reduce the volume of the device or structure, as shown in fig. 2 or fig. 3, a hydraulic telescoping mechanism 15 is mounted on the upper flange 1 through a frame, and a telescoping rod of the hydraulic telescoping mechanism is connected with the connecting rod 9 through a connecting piece, so that the telescoping direction of the telescoping mechanism 15 is consistent with the movement direction of the connecting rod 9, that is, when the telescoping mechanism 15 extends, the connecting rod 9 also extends out from the vacuum tube 2, and otherwise retracts. Because the metal water pipe 4 is provided with the plurality of water spraying ports 5 along the length direction, the sliding stroke of the outer sleeve 6 is lengthened due to the increase of the number of the water spraying ports 5, and therefore, the connecting rod 9 is arranged at the bottom of the outer sleeve 6, not only can a certain supporting effect be achieved on the outer sleeve 6, but also the length of the part, extending out of the vacuum pipe 2, of the connecting rod 9 can be shortened. It should be noted that the sizing sleeve of the vacuum tube 2 is generally horizontally installed in the transverse direction, but needs to be erected during assembly, so that the flange plates are divided into an upper flange plate and a lower flange plate, but are horizontally arranged between the upper flange plate and the lower flange plate 3 of a user. When the outer sleeve is close to and clings to the lower flange, the connected waterproof cloth is compressed and curled, when the outer sleeve slides, the waterproof cloth is straightened, and when the outer sleeve rotates, the waterproof cloth still can provide the rotation redundancy of movement due to the soft material.

Example two.

The present embodiment is made on the basis of the first embodiment. The present embodiment is provided to enable the connecting rod 9 to rotate the outer sleeve 6, and since the connecting rod 9 is located below the outer sleeve 6, the effect of rotation is achieved.

A gear 12 cover 10 is fixed at the bottom of the outer sleeve 6, the gear 12 cover 10 allows the connecting rod 9 to be inserted and rotate, a rack and pinion mechanism is arranged in the gear 12 cover 10, a rack is a bent rack 11 and is fixed on the outer sleeve 6 and is bent along the outer surface of the outer sleeve 6, a gear 12 is fixed at the tail end of the connecting rod 9, and the rotation of the gear 12 drives the rack 11 to rotate, so that the outer sleeve 6 rotates. The power of the rotation of the connecting rod 9 comes from a motor 13, the motor 13 is positioned outside the upper flange plate 1 and is wrapped in a motor cover 14, the motor cover 14 is connected with a hydraulic telescopic mechanism 15, and the outer sleeve 6 can be driven to perform telescopic motion as long as the motor cover 14 is driven to perform telescopic motion.

In this embodiment, as shown in fig. 6, the dotted line represents the water jet 5, the length of the water jet 5 of the metal water pipe 4 is greater than the length of the water permeable window 7, and after the motor 13 is started, the water permeable window 7 swings around the axis of the outer sleeve 6, and the angle of the sprayed water column is constantly changed during the swing, so that the cooling water can be more uniformly sprayed onto the metal member.
