Description

Technical Field

[0001] This utility model relates to the field of centralized lubrication technology, specifically a dual-line explosion-proof oil distribution tank. Background Technology

[0002] The dual-line dry grease intelligent centralized lubrication system is a highly efficient and precise automated lubrication device designed specifically for the multi-point lubrication needs of large industrial machinery. This system uses two main oil pipes to alternately supply pressure, quantitatively delivering dry grease (lubricating grease) to each lubrication point, significantly reducing manual maintenance costs and improving equipment reliability.

[0003] Dual-line dry oil intelligent centralized lubrication systems typically use a hydraulic cylinder to drive a piston plate in reciprocating motion within the oil distribution tank. This method effectively forces the lubricating grease from the tank into the dual-line oil pipes. However, in practical applications, the dual-line oil pipes may encounter blockages. If the system continues to apply pressure to the oil distribution tank after blockage, the internal pressure may rise sharply, potentially leading to a tank rupture. Therefore, a dual-line explosion-proof oil distribution tank is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dual-line explosion-proof oil distribution tank to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-line explosion-proof oil distribution tank, comprising an oil distribution tank body, a dual-line oil pipe at the bottom of the oil distribution tank body, a piston plate movably installed inside the oil distribution tank body, an oil cylinder at the middle position of the piston plate, an installation hole on the piston plate, a pressure relief mechanism at the installation hole, the pressure relief mechanism comprising a plug installed on the piston plate, a pressure relief hole on the plug, a pressure relief pipe inside the pressure relief hole, a pressure relief notch on the side wall of the pressure relief pipe, a first spring inside the pressure relief pipe, a plunger movably installed inside the pressure relief pipe, and an emergency stop mechanism fixedly installed at the upper end of the pressure relief pipe.

[0006] Preferably, the plug has a reflux hole, the upper end of the reflux hole is provided with a sealing plug, a pressure ring plate is movably installed on the pressure relief pipe, and the upper end of the plug has a material receiving groove.

[0007] Preferably, the pressure relief hole is provided with threads, and the pressure relief pipe is connected to the pressure relief hole through the threads.

[0008] Preferably, one end of the first spring is connected to the plunger, and the other end of the first spring is connected to the top of the pressure relief pipe. The plug is installed on the piston plate through the mounting hole. A stop ring is provided at the lower edge of the pressure relief pipe, and the plunger is restricted inside the pressure relief pipe by the stop ring.

[0009] Preferably, the emergency stop mechanism includes a housing fixedly installed on the upper end of the pressure relief pipe and a push rod fixedly installed in the middle of the plunger. A terminal block is fixedly installed on the housing, and an oil pump wire is connected to the terminal block. An insulating guide rod is fixedly installed inside the housing. A second spring is sleeved on the insulating guide rod, and a conductor block is movably installed on the insulating guide rod, with the conductor block aligned vertically with the terminal block.

[0010] Preferably, the pressure relief pipe has a through hole at its upper end, the top rod extends into the pressure relief pipe through the through hole, and the conductor block has a movable hole, through which the conductor block is movably mounted on the insulating guide rod.

[0011] Preferably, one end of the second spring is connected to the conductor block, and the other end of the second spring is connected to the top of the mechanism housing. The push rod is movably installed in the pressure relief pipe through a plunger, and the oil pump wire is fixedly installed on the terminal block by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, as the internal pressure of the oil distributor increases, the first spring is compressed, causing the plunger to displace above the pressure relief opening. At this time, the oil distributor is connected to the outside, allowing the lubricating grease inside the distributor to be discharged through the pressure relief opening, thereby reducing the internal pressure and preventing the oil distributor from rupturing. Furthermore, the lubricating grease discharged through the pressure relief opening falls into the receiving groove. The user can open the sealing plug and push the pressure ring plate downwards to force the lubricating grease in the receiving groove back into the oil distributor, thus reducing lubricating oil waste.

[0014] 2. In this application, during the pressure relief process, the upward movement of the plunger will drive the push rod to rise synchronously. During the upward movement, the push rod will exert force on the conductor block, causing the oil pump wire to disconnect. After the oil pump wire is disconnected, the oil pump of the cylinder will lose power supply and stop operating, realizing the automatic emergency stop of the piston plate and effectively preventing the leakage of excessive lubricating grease.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a dual-line explosion-proof oil distribution tank, including an oil distribution tank body 1, a dual-line oil pipe 2 at the bottom of the oil distribution tank body 1, a piston plate 3 movably installed inside the oil distribution tank body 1, an oil cylinder 4 at the middle position of the piston plate 3, an installation hole 5 on the piston plate 3, a pressure relief mechanism 6 at the installation hole 5, and an emergency stop mechanism 7 fixedly installed at the upper end of the pressure relief pipe 606. The pressure relief mechanism 6 can relieve pressure when the oil pressure inside the oil distribution tank body 1 is too high, preventing the oil distribution tank body 1 from bursting, and the emergency stop mechanism 7 can quickly stop the system operation when the oil pressure inside the oil distribution tank body 1 is too high, reducing the possible danger.

[0022] like Figure 2 and Figure 3 As shown, the pressure relief mechanism 6 includes a plug 603 mounted on the piston plate 3. The plug 603 has a pressure relief hole 609. A pressure relief pipe 606 is provided in the pressure relief hole 609. A pressure relief notch 610 is provided on the side wall of the pressure relief pipe 606. A first spring 605 is provided in the pressure relief pipe 606. A plunger 608 is movably installed in the pressure relief pipe 606. A return hole 604 is provided on the plug 603. A sealing plug 602 is provided at the upper end of the return hole 604. A pressure ring plate 601 is movably installed on the pressure relief pipe 606. A material receiving groove 607 is provided at the upper end of the plug 603. A thread is provided in the pressure relief hole 609. The pressure relief pipe 606 is connected to the pressure relief hole 609 by the thread.

[0023] Specifically, as the pressure inside the oil distributor body 1 gradually increases, the first spring 605 is compressed under the pressure. This process causes the plunger 608 to move, eventually reaching a position above the pressure relief opening 610. Once the plunger 608 successfully moves above the pressure relief opening 610, the oil distributor body 1 becomes connected to the external environment. In this way, the lubricating grease inside the oil distributor body 1 can be discharged into the external environment through the opened pressure relief opening 610. This effectively reduces the internal pressure of the oil distributor body 1, thus preventing the risk of the oil distributor body 1 bursting due to excessive pressure. Furthermore, the lubricating grease discharged through the pressure relief opening 610 naturally falls into the receiving groove 607 below. When needed, the user can easily re-push the lubricating grease from the receiving groove 607 back into the oil distributor body 1 by opening the sealing plug 602 and pushing down the pressure ring plate 601. This design not only ensures the effective recycling of lubricating grease but also greatly reduces lubricating oil waste and improves resource utilization.

[0024] like Figure 2 and Figure 4 As shown, the emergency stop mechanism 7 includes a mechanism housing 701 fixedly installed on the upper end of the pressure relief pipe 606 and a push rod 703 fixedly installed in the middle position of the plunger 608. A terminal block 707 is fixedly installed on the mechanism housing 701, and an oil pump wire 702 is connected to the terminal block 707. An insulating guide rod 704 is fixedly installed inside the mechanism housing 701. A second spring 705 is sleeved on the insulating guide rod 704. A conductor block 706 is movably installed on the insulating guide rod 704, and the conductor block 706 is vertically aligned with the terminal block 707. A through hole is opened at the upper end of the pressure relief pipe 606, and the push rod 703 extends into the pressure relief pipe 606 through the through hole. A movable hole is opened on the conductor block 706, and the conductor block 706 is movably installed on the insulating guide rod 704 through the movable hole.

[0025] Specifically, during the depressurization process, the plunger 608 moves upward, which in turn moves the push rod 703 upward. As the push rod 703 rises, it applies force to lift the conductor block 706 located above. When the conductor block 706 is lifted, the oil pump wire 702 is disconnected. Once the oil pump wire 702 is disconnected, the oil pump of the cylinder 4 loses its power supply and stops working. After the oil pump stops working, the movement of the cylinder 4 also stops, thus realizing the automatic emergency stop function of the piston plate 3. The purpose of this function is to prevent excessive lubricating grease leakage in the lubrication system and ensure the safety and stability of the system.

[0026] Working Principle: During operation, the piston plate 3 is driven downward by the hydraulic cylinder 4, causing the lubricating grease in the oil distribution tank body 1 to be discharged through the dual-line oil pipe 2. When the dual-line oil pipe 2 is blocked, the pressure inside the oil distribution tank body 1 will increase. As the pressure inside the oil distribution tank body 1 increases, the first spring 605 will be compressed, causing the plunger 608 to move above the pressure relief opening 610. After the plunger 608 moves above the pressure relief opening 610, the oil distribution tank body 1 will be connected to the outside, allowing the lubricating grease inside the oil distribution tank body 1 to be discharged through the pressure relief opening 610, reducing the internal pressure of the oil distribution tank body 1 and preventing the oil distribution tank body 1 from bursting. The lubricating grease discharged through the pressure relief opening 610 will fall into the receiving groove 607. The user can open the sealing plug 602 and push down the pressure ring plate 601 to force the lubricating grease in the receiving groove 607 back into the oil distribution tank body 1, reducing the waste of lubricating grease. Furthermore, during the depressurization process, the upward-moving plunger 608 will drive the push rod 703 to move upward. When the push rod 703 moves upward, it will push the conductor block 706 upward, thereby disconnecting the oil pump wire 702. After disconnecting the oil pump wire 702, the oil pump of the oil cylinder 4 will be de-energized, causing the oil cylinder 4 to stop moving, thereby realizing the automatic emergency stop of the piston plate 3 and preventing excessive lubricating grease leakage.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
