Description

Technical Field

[0001] The utility model belongs to the technical field of water-cooled spray systems, and particularly relates to a quick connection device for a water-cooled spray system. Background Art

[0002] The walking-rack cooling bed is an important device in the steel rolling production line. Its main function is to cool the hot-rolled steel to facilitate subsequent processing. The performance of the cooling bed directly affects the quality of the rolled pieces and the continuity of production. The water-cooled spray system of the cooling bed is arranged in the center of the cooling bed and consists of more than a hundred spray branches. The spray branches are connected to the spray nozzles through high-pressure hoses and are responsible for forcibly cooling the rolled pieces to meet the temperature requirements before the rolled pieces enter the straightening machine. However, impurities are likely to accumulate in the spray branches and spray nozzles, making it difficult to dredge the pipes, and the service life after dredging is short. Therefore, it needs to be regularly replaced and maintained. Otherwise, during the cooling process of some steel, the spray water volume will be insufficient or even there will be no water, and the temperature difference between the steel pieces is large, which is likely to cause fluctuations and instability in the bending degree of the steel.

[0003] To address the above problems, operators are usually arranged to batch replace and repair the spray branches and clean the nozzles during the process time. However, since most of the existing spray branches and high-pressure hoses are connected by nuts, it is relatively difficult to disassemble, and the nuts age after a certain period of use, resulting in a limited number of spray branches that can be replaced within the limited process time, far from meeting the number of spray branches that need to be replaced due to blockage, and causing the water-cooled spray system of the cooling bed to fail to achieve an ideal operating effect.

[0004] Therefore, there is a need for a quick connection device for a water-cooled spray system that can achieve quick disassembly and assembly between the spray branches and the high-pressure hoses. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a quick connection device for a water-cooled spray system, which can achieve quick disassembly and assembly between the spray branches and the high-pressure hoses, effectively increase the number of disassembled and replaced spray branches within the process time, reduce the labor intensity, and enable the water-cooled spray system to achieve a good cycle replacement effect and improve the production efficiency.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A quick connection device for a water-cooled spray system, comprising a plug and a socket which are respectively connected to a spray branch pipe and a high-pressure hose and are of an annular structure; the socket includes a sleeve connected to the high-pressure hose and provided with a sealing ring inside, two buckle components radially symmetrically arranged on the side wall of the sleeve, and a plurality of elastic positioning blocks arranged at intervals along the circumferential direction of the side wall of the sleeve and capable of moving radially along it; the plug is provided with grooves on its outer wall circumference to adapt to the elastic positioning blocks and the buckle components. When the plug is inserted into the sleeve of the socket and abuts against the sealing ring inside it, each elastic positioning block and the buckle component on the sleeve can respectively penetrate its side wall and cooperate with the grooves on the plug for positioning and locking.

[0008] A further improvement of the technical solution of the present utility model lies in that: the groove of the plug is an arc-shaped groove; the buckle component is a handle-type structure vertically arranged on the side wall of the sleeve, including brackets symmetrically arranged on the outer wall of the sleeve, a buckle head rotatably arranged between the two brackets through a pin shaft and penetrating the side wall of the sleeve, and a wrench connected to the buckle head.

[0009] A further improvement of the technical solution of the present utility model lies in that: the pin shaft is eccentrically arranged on the outer side close to the buckle head, the side wall of the buckle head far from the pin shaft is arranged as an arc surface adapted to the arc-shaped groove of the plug, and the side wall of it close to the pin shaft is arranged as a plane; one end of the wrench is integrally formed with the buckle head and is connected to its plane side and arc surface side, and the other end of it is tilted outwards to form a bent handle.

[0010] A further improvement of the technical solution of the present utility model lies in that: the elastic positioning block is a semi-circular structure vertically arranged on the side wall of the sleeve, its flat end is connected to the outer side wall of the sleeve through return springs symmetrically arranged on both sides of it, and its arc surface end penetrates the side wall of the sleeve and is adapted to the arc-shaped groove of the plug.

[0011] A further improvement of the technical solution of the present utility model lies in that: an anti-slip rubber sleeve is sleeved on the arc-shaped groove of the plug.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model is:

[0013] The quick connection device of the present utility model for a water-cooled spray system can realize the quick disassembly and assembly between the spray branch pipe and the high-pressure hose, effectively increase the number of disassembly and replacement of the spray branch pipe within the process time, reduce the labor intensity, and at the same time enable the water-cooled spray system to achieve a good cycle replacement effect, improving the production efficiency.

[0014] The plug and socket of the present utility model, which are respectively connected to the spray branch pipe and the high-pressure hose and are of an annular structure, cooperate with each other to realize quick insertion, thereby realizing the quick disassembly and assembly between the spray branch pipe and the high-pressure hose.

[0015] The utility model adopts a structure that buckle components are symmetrically arranged radially on the side wall of the socket sleeve, and a number of elastic positioning blocks are arranged at intervals along the circumferential direction of the side wall of the sleeve, and each elastic positioning block can move radially. When the spray branch pipe is inserted into the sleeve of the socket connected to the high-pressure hose through the plug, a number of elastic positioning blocks on the sleeve can radially penetrate through its side wall to position on the groove of the plug, providing a circumferential clamping force for the plug, effectively avoiding the detachment of the high-pressure hose from the spray branch pipe during the installation process. On this basis, the two buckle components adopted by the utility model can penetrate through the side wall of the sleeve to lock on the groove of the plug, thereby fastening the plug in the sleeve of the socket, thus completing the rapid installation between the spray branch pipe and the high-pressure hose.

[0016] The elastic positioning block adopted by the utility model is of a semi-circular structure. Its flat end is connected to the outer side wall of the sleeve through return springs symmetrically arranged on both sides of it. Its arc end penetrates through the side wall of the sleeve and is adapted to the arc-shaped groove of the plug, enabling the sleeve to be positioned on the arc-shaped groove of the plug through each elastic positioning block, and at the same time enabling smooth and rapid insertion and removal between the plug and the sleeve, which is beneficial to the rapid disassembly and assembly between the spray branch pipe and the high-pressure hose, and thus cooperates with the buckle components to effectively increase the number of spray branch pipes disassembled and replaced within the process time.

[0020] The following further describes the utility model in detail with reference to the embodiments:

[0021] Such as Figure 1 And Figure 2As shown in the figure, the utility model provides a quick connection device for a water-cooled spraying system, which includes a plug 3 and a socket. The plug 3 and the socket are respectively connected to the spraying branch pipe 1 and the high-pressure hose 2, and both the plug 3 and the socket are of annular structures. Specifically, the socket includes a sleeve 4, two buckle components, and several elastic positioning blocks 6. The sleeve 4 is connected to the high-pressure hose 2, and a sealing ring 5 is arranged inside the sleeve 4. The two buckle components are radially symmetrically arranged on the side wall of the sleeve 4. The several elastic positioning blocks 6 are arranged at intervals along the circumferential direction of the side wall of the sleeve 4 and can move radially along it. Each elastic positioning block 6 cooperates with the two buckle components, that is, each elastic positioning block 6 is distributed between the two buckle components. Preferably, each elastic positioning block 6 is evenly and symmetrically distributed between the two buckle components. The plug 3 is provided with a groove on its outer wall circumference to adapt to the elastic positioning block 6 and the buckle component. When the spraying branch pipe 1 is inserted into the sleeve 4 of the socket on the high-pressure hose 2 through the plug 3, the end of the plug 3 abuts against the sealing ring 5 inside the sleeve 4. Each elastic positioning block 6 and the buckle component on the sleeve 4 can respectively penetrate its side wall and cooperate to quickly position and lock on the groove of the plug 3, so as to realize the quick disassembly and assembly between the spraying branch pipe and the high-pressure hose.

[0022] Furthermore, in order to better realize the quick disassembly and assembly between the plug 3 and the sleeve 4, the groove of the plug 3 is an arc-shaped groove, and the buckle component is a handle-type structure vertically arranged on the side wall of the sleeve 4, that is, arranged along the length direction of the sleeve 4. Specifically, the buckle component includes two brackets 7, a pin shaft 9, a buckle head 8, and a wrench. Among them, the two brackets 7 are symmetrically arranged on the outer wall of the sleeve 4. The buckle head 8 is rotatably arranged between the two brackets 7 through the pin shaft 9 and penetrates the side wall of the sleeve 4. The wrench is connected to the buckle head 8. The pin shaft 9 is horizontally arranged on the sleeve 4 and is eccentrically arranged near the outside of the buckle head 8 at the same time. The side wall of the buckle head 8 away from the pin shaft 9 is adapted to the arc-shaped groove of the plug 3 and is set as an arc surface, and its side wall close to the pin shaft 9 is set as a plane. Correspondingly, through holes adapted to the buckle heads 8 of the two buckle components and adapted to several elastic positioning blocks 6 are respectively opened on the side wall of the sleeve 4.

[0023] Thus, when the spray branch pipe 1 is inserted into the socket sleeve 4 of the high-pressure hose 2 through the plug 3, the user can respectively use the wrenches of the two snap components to turn the buckle 8 to make it rotate, so that the arc-shaped side of the buckle 8 faces the side wall of the sleeve 4 and penetrates it, and then lock it on the arc-shaped groove of the plug 3, thereby completing the quick installation between the spray branch pipe 1 and the high-pressure hose 2; when the spray branch pipe 1 and the high-pressure hose 2 need to be quickly disassembled, the user needs to respectively use the wrenches of the two snap components to turn the buckle 8 to make it rotate, so that the flat side of the buckle 8 faces the side wall of the sleeve 4, and there is a certain gap between the flat side of the buckle 8 and the arc-shaped groove of the plug 3, thereby releasing the locking mechanism of the plug 3 and enabling the quick disassembly between the spray branch pipe 1 and the high-pressure hose 2. To facilitate turning the wrench, one end of the wrench is integrally formed with the buckle 8 and is connected to its flat side and arc-shaped side, and the other end is warped outward to form a bent handle 10. The setting of the bent handle 10 is more conducive to the user to lift and open the wrench and press for locking operation.

[0024] Before the two snap components perform the locking operation on the plug 3, in order to better realize the positioning between the plug 3 and the sleeve 4 and prevent the connected high-pressure hose 2 from detaching from the spray branch pipe 1 before the locking operation, each elastic positioning block 6 is a semi-circular structure vertically arranged on the side wall of the sleeve 4. Its flat end is connected to the outer side wall of the sleeve 4 through the return springs 11 symmetrically arranged on both sides of it. Its arc-shaped end penetrates the side wall of the sleeve 4 and is adapted to the arc-shaped groove of the plug 3. Therefore, each elastic positioning block 6 can move along the radial direction of the sleeve 4, thereby enabling the quick loading and unloading between the plug 3 and the sleeve 4 smoothly and quickly. At the same time, each elastic positioning block 6 can also provide a circumferential clamping force to the plug 3 to position it in the sleeve 4 and prevent the connected high-pressure hose 2 from detaching from the spray branch pipe 1. To better provide the clamping force, an anti-slip rubber sleeve 12 is sleeved on the arc-shaped groove of the plug 3 to increase the friction force between the arc-shaped end of the elastic positioning block 6 and the arc-shaped groove of the plug 3.
