Description

Technical Field

[0001] The utility model relates to the technical field of liquid loading and unloading equipment, in particular to a new type of flange quick connection device. Background Art

[0002] The commonly used flange quick connection devices on loading and unloading arms are generally manual structures, which are all clamped and loosened by manual application of special tools. Due to problems such as purging, there may be residual media in the pipe. For volatile media, it is dangerous to use a blind plate seal, and a valve needs to be set as a cut-off valve. After the special setting, the weight of the pipe end of the loading and unloading arm will be relatively large and the length will increase. To ensure balance and the drive of the whole machine, all structures need to be increased, greatly increasing the manufacturing cost. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a new type of flange quick connection device with a valve and a drive, which can automatically cut off when there is residual media in the pipe and greatly reduce the overall weight, aiming at the deficiencies of the prior art.

[0004] The technical problem to be solved by the utility model is realized through the following technical solutions. A new type of flange quick connection device includes a valve component. The valve component includes a valve body and a valve drive. A valve core and a valve rod are installed on the valve body, and a seal is provided between the valve core and the valve rod. The valve drive includes a cam and a hinge shaft oil cylinder. The top of the valve rod is connected to the hinge shaft oil cylinder through the cam, and the hinge shaft oil cylinder drives the valve rod to rotate to open and close the valve. The valve component and the quick connection device are taken as a whole, reducing the weight of the whole device and the size.

[0005] One end of the valve body is provided with a joint flange, and a slewing mechanism is provided on the side of the joint flange. The slewing mechanism includes a slewing bearing and a clamping drive assembly. The slewing bearing includes a support outer ring and a support inner ring, and the clamping drive assembly is arranged between the support outer ring and the support inner ring. Quick and reliable connection is realized through the slewing mechanism and the clamping drive assembly. The valve drive makes the operation of opening and closing the valve more convenient, and the cooperation of the seal and the slewing mechanism is reliably sealed.

[0006] The other end of the valve body is provided with a ship connection flange for docking with the ship manifold flange, and a pressing mechanism is provided on the side of the ship connection flange. The pressing mechanism includes a connecting rod assembly and a plurality of claw assemblies evenly distributed along the circumference of the ship connection flange. Each claw assembly includes an upper claw and a lower claw. The tail ends of the upper claw and the lower claw are hinged to the valve body through a pin shaft. A spring arm is provided between the head of the upper claw and the head of the lower claw. The upper claw is connected to the support outer ring through the connecting rod assembly. The clamping drive assembly drives the relative rotation of the support outer ring and the support inner ring. The rotation of the support outer ring drives the upper claw to rotate along the pin shaft through the connecting rod assembly, pushing the spring arm to apply a load to the lower claw to clamp the ship manifold flange.

[0007] Ensure that the receiving flange can be reliably docked with the ship manifold flange, and provide sufficient force through the clamping mechanism to make the connection more firm and secure.

[0008] As a further solution of the present utility model, the clamping drive assembly includes a clamping oil cylinder and a cylinder seat. The cylinder seat includes an inner ring cylinder seat and an outer ring cylinder seat. One end of the clamping oil cylinder is connected to the support inner ring through the inner ring cylinder seat, and the other end of the clamping oil cylinder is connected to the support outer ring through the outer ring cylinder seat.

[0009] The inner ring cylinder seat and the outer ring cylinder seat provide a firm connection between the clamping oil cylinder and the support inner ring and the support outer ring, which is stable and reliable during the connection process. The clamping oil cylinder can precisely control the clamping force, adjust the tightening strength of the connection according to requirements, and adapt to different working environments and application requirements. Through the inner ring and the support outer ring, it effectively prevents the clamping oil cylinder from moving or falling off during use, improving the safety and reliability of the overall connection.

[0010] As a further solution of the present utility model, the connecting rod assembly includes a connecting rod. One end of the connecting rod is provided with a hinge piece, and the connecting rod is connected to the support outer ring through the hinge piece. The other end of the connecting rod is provided with a lifting ring, and a universal bolt is arranged inside the lifting ring. The universal bolt is threadedly connected with the upper claw.

[0011] The hinge piece and the universal bolt enable the connecting rod assembly to be flexibly adjusted during installation and use to adapt to different working requirements and connection positions. The structural connection of the hinge piece and the lifting ring is firm and flexible, ensuring the safety and reliability of the connection.

[0012] As a further solution of the present utility model, after the connecting rod assembly rotates and locks, a self-locking angle is formed, and the connecting rod without power drive remains stationary. The rotation of all claw assemblies is driven by the same support outer ring, making its coordination high, and a self-locking angle is formed after rotation and locking, and it will not loosen without power.

[0013] As a further solution of the present utility model, the head of the upper claw is provided with an inward concave arc-shaped bayonet. The arc-shaped bayonet includes an arc segment and a straight segment. The tail end of the straight segment is hinged to the tail end of the lower claw. The spring arm is arranged at the free end of the arc segment and the free end of the lower claw. The lower claw is in a right-angled hook shape, and a clamping block is arranged on the right-angled hook. The surface of the clamping block forms a clamping surface that cooperates with the flange.

[0014] As a further solution of the present utility model, the spring arm includes a double-headed screw. A spring is threaded through the double-headed screw. A threaded hole is provided on the upper claw, and a countersunk screw hole is provided on the lower claw. One end of the double-headed screw passes through the threaded hole and is fastened by a nut, and the other end of the double-headed screw is screwed into the countersunk screw hole.

[0015] The arc-shaped bayonet of the upper claw and the right-angle hook-like structure of the lower claw ensure the firm fixation of the connecting piece during operation, avoiding potential safety hazards caused by loosening or displacement. The design of the clamping block helps to increase the friction and anti-slip ability, improving the safety and reliability of the connection.

[0016] The beneficial effects of the present utility model are as follows: A new type of flange quick connection device provided by the present utility model includes a valve component. The valve component and the quick connection device are regarded as a whole, reducing the weight and size of the entire device. One end of the valve body is provided with a joint flange, and a rotary mechanism is provided on the side of the joint flange. Quick and reliable connection is achieved through the rotary mechanism and the clamping drive assembly. The valve drive makes the operation of opening and closing the valve more convenient, and the cooperation between the seal and the rotary mechanism is reliably sealed.

[0017] The clamping oil cylinder of the pressing mechanism can precisely control the clamping force, adjust the fastening strength of the connection according to requirements, and adapt to different working environments and application needs. Through the inner ring and the supporting outer ring, it effectively prevents the movement or detachment of the clamping oil cylinder during use, improving the safety and reliability of the overall connection. The valve component and the flange connection are driven by a hydraulic clamping oil cylinder, eliminating the need for manual labor. The spring load of the claw assembly can be adjusted by a double-headed screw to make its elastic force the same, suitable for flanges of different thicknesses. The clamping action is driven by the same supporting outer ring, with high coordination. Description of the Drawings

[0024] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0025] As Figures 1 to 3 shown, a new type of flange quick connection device includes a valve component. The valve component includes a valve body 1 and a valve drive 2. A valve core and a valve stem 202 are installed on the valve body 1, and a seal is provided between the valve core and the valve stem. The valve drive includes a cam 201 and a hinge shaft oil cylinder 203. The top of the valve stem is connected to the hinge shaft oil cylinder through the cam, and the hinge shaft oil cylinder drives the valve stem to rotate to open and close the valve.

[0026] One end of the valve body is provided with a joint flange, and a slewing mechanism 3 is provided on the side of the joint flange. The slewing mechanism includes a slewing support and a clamping drive assembly. The slewing support includes a support outer ring 7 and a support inner ring 6, and the clamping drive assembly is arranged between the support outer ring and the support inner ring; the clamping drive assembly includes a clamping oil cylinder 301 and a cylinder seat. The cylinder seat includes an inner ring cylinder seat 302 and an outer ring cylinder seat 303. One end of the clamping oil cylinder is connected to the support inner ring 6 through the inner ring cylinder seat, and the other end of the clamping oil cylinder is connected to the support outer ring 7 through the outer ring cylinder seat. The support outer ring drives the relative movement with the support inner ring through the cylinder rod of the clamping oil cylinder.

[0027] Before the work starts, the valve is in the closed state, and the hinge shaft oil cylinder drives the valve stem to be in the unextended state. When it is necessary to clamp the flange, the clamping oil cylinder drives the valve stem to extend, and drives the support outer ring to rotate through the outer ring cylinder seat.

[0028] On the other end of the valve body, there is a ship connection flange for docking with the ship manifold flange. A pressing mechanism 4 is provided on the side of the ship connection flange. The pressing mechanism includes a connecting rod assembly and a number of claw assemblies evenly distributed along the circumference of the ship connection flange. The claw assembly 5 includes an upper claw 501 and a lower claw 503. The tail ends of the upper claw and the lower claw are hinged to the valve body through a pin shaft. A spring arm 502 is provided between the head of the upper claw and the head of the lower claw. The upper claw is connected to the support outer ring through the connecting rod assembly. The clamping drive assembly drives the support outer ring 7 to rotate relative to the support inner ring 6. The rotation of the support outer ring drives the upper claw to rotate along the pin shaft through the connecting rod assembly, pushing the spring arm to apply a load to the lower claw and clamping the ship manifold flange. The upper claw of the claw assembly is driven by the rotation of the support outer ring connected through the connecting rod part, and rotates through the pin shaft 13 to push the spring part to apply a load to the lower claw, so as to clamp the ship connection flange;

[0029] The connecting rod assembly includes a connecting rod 402. The connecting rod is a double-headed screw. One end of the connecting rod is provided with a hinge piece 401. The connecting rod is connected to the support outer ring through the hinge piece 401. The other end of the connecting rod is provided with a lifting ring 404. A universal bolt is provided in the lifting ring. The universal bolt is threadedly connected to the upper claw 501. After the connecting rod assembly rotates and locks, a self-locking angle is formed, and the connecting rod remains stationary without power drive.

[0030] The head of the upper claw 501 is provided with a concave arc-shaped bayonet. The arc-shaped bayonet includes an arc segment and a straight segment. The tail end of the straight segment is hinged to the tail end of the lower claw. The spring arm 502 is arranged at the free end of the arc segment and the free end of the lower claw. The spring arm includes a double-headed screw 521. A spring 522 is sleeved on the double-headed screw. A threaded hole is provided on the upper claw, and a countersunk screw hole is provided on the lower claw. One end of the double-headed screw passes through the threaded hole and is fastened by a nut. The other end of the double-headed screw is screwed into the countersunk screw hole. The lower claw is in the shape of a right-angle hook, and a clamping block is provided on the right-angle hook. The surface of the clamping block forms a clamping surface for mating with the flange. The claw assembly can adjust the spring length through the double-headed screw for different thickness flanges, so as to adjust the pressing force and achieve the purpose of clamping the flange.

[0031] While the support outer ring rotates, the connecting rod part drives the claw assembly to rotate and open around the pin shaft. After the flange is aligned, the valve stem of the clamping oil cylinder retracts, driving the support outer ring to rotate through the outer ring cylinder seat. While the support outer ring rotates, the connecting rod part drives the claw assembly to rotate and clamp around the pin shaft. The double-headed screw is adjusted through a torque wrench, so that the load of each claw assembly is the same.

[0032] At the beginning of the work, the valve stem of the hinge shaft oil cylinder is in the extended state, driving the valve stem to rotate and open the valve, and the flow channel can be unblocked, being in an operable state.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0034] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
