Description

Technical Field

[0001] The invention belongs to the technical field of high-pressure oil rapid discharge and diversion, and relates to high-pressure oil rapid discharge and diversion equipment for a hydraulic system of large equipment and a use method thereof. Background Art

[0002] The power for the effective movement of each functional component of the hydraulic system of large equipment mainly depends on the hydraulic system with hydraulic oil as the transmission medium. Therefore, after the operator completes the debugging work of the hydraulic system of large equipment, he should comprehensively check the correctness of the installation of each pipeline of the relevant hydraulic system and the sealing of the conduit joint connection.

[0003] When debugging and checking the function of the hydraulic system of large equipment, after the work is completed, the high-pressure oil remaining in the hydraulic pipeline needs to be quickly discharged to the outside of the equipment through the oil drain pipe on the equipment. After that, the operator visually checks whether there is oil leakage and sealing integrity of the conduit joints of the relevant pressure-storing pipelines, thereby ending the entire debugging and inspection process. However, since the outer diameter of the oil drain pipe for this function debugging and inspection is very thin, the exposed effective length is very short, and it is located at the plane structure of the large equipment, the oil will be sprayed everywhere due to the instantaneous pressure relief of the oil when the high-pressure oil is actually discharged, covering the large equipment's own structure, surrounding equipment tooling and working ground, and sometimes a large amount of oil mist will be generated. Therefore, when completing the debugging and inspection of this operating function, the operator can only cover the large equipment's own structure and surrounding equipment tooling with oil-absorbing cotton in advance, and cover the ground with sawdust and powder. After the high-pressure oil discharge work is completed, wait for the surrounding oil mist to dissipate, and the operator can complete the large equipment's own structure, surrounding equipment tooling, working ground and related conduit joints. Sealing inspection, cleaning and wiping work. Although the above method can also complete this work well, it also reflects some problems. First, the entire discharge process of high-pressure oil will cause oil to spray everywhere, resulting in a large amount of oil cleaning work for the operator; second, each time this function inspection requires the use of a large amount of oil-absorbing cotton and sawdust powder, it leads to high manufacturing costs and high work intensity; third, the instantaneous pressure relief of high-pressure oil will cause a large amount of oil mist to be generated at the discharge pipe, seriously polluting the surrounding working environment and the health of the operator; fourth, after each high-pressure oil discharge, the operator has to wait for the oil mist to dissipate before conducting relevant inspections and subsequent work, thus affecting the entire production cycle.

Its main function is to prevent the end face of the locking nut from rubbing against the end face of the arc-shaped movable clamping plate during rotation, resulting in wear of the end faces of the two.

[0017] The telescopic positioning screw is made of wear-resistant and high-strength aluminum material and has a cylindrical structure. Its main function is to connect the arc-shaped static clamping plate and the stop rod, and in actual work, it is adjusted according to the relative position relationship;

[0018] The fastening nut is made of wear-resistant stainless steel. Two of them are provided in the device, which are respectively installed at the threaded rods at both ends of the telescopic positioning screw.

[0020] The suction cup clamping system includes a suction cup base, a stop rod, a hexagon socket fixing bolt, a rubber suction cup, a square tightening device, a suction cup tightening handle, and a connecting pin. The specific structure is as follows Figure 1 , Figure 3 , Figure 4 , Figure 5 shown.

[0021] The suction cup base is mainly made of high-hardness aluminum material, and has a circular chassis with a tightening handle structure on the upper end. Its main function is to provide a rigid adsorption support for the rubber suction cup during operation;

[0022] The stop rod is mainly made of wear-resistant aluminum material and has a cylindrical shape. Its main function is to provide a connection device for the relative movement of the telescopic positioning screw relative to the suction cup base;

[0023] The hexagon socket fixing bolt is made of stainless steel. Two are provided in the device. Its main function is to fix it to the handle support arm on the same side as the suction cup tightening handle at the upper end of the suction cup base through the stop rod's own support.

[0024] The rubber suction cup is made of a colloid material with good elasticity, wear resistance and corrosion resistance, and has a circular structure in shape. When it is in a glue liquid state during the manufacturing process, it includes the circular plane structure at the lower end of the square tightening device, and then solidifies and forms a connection relationship.

Its main function is to complete the connection between the square tightening device and the suction cup tightening handle. The connecting pin is an interference fit with the suction cup tightening handle and a clearance fit with the square tightening device.

[0028] The rapid flow diversion system includes a comprehensive signal follower collector, a reducer adapter, an oil mist liquefier, an explosion-proof steel hose, and a clamp. The specific structure is as follows: Figure 2 shown.

[0029] The integrated signal follower collector is mainly composed of a time acquisition module, a pressure acquisition module, a flow acquisition module and a numerical conversion display module. The main function is to record the pressure, flow, time and other related data when the high-pressure oil is discharged instantly, and display the recorded data through a liquid crystal display screen, thereby determining the integrity of the pipeline seal involved in the functional debugging inspection of the hydraulic system of the large equipment; Figure 7 shown.

[0030] The reducer adapter is mainly made of aluminum material and has a cylindrical shape. One end with a large diameter inner hole is connected to one end of an explosion-proof steel hose through a clamp, and then clamped in the middle through hole formed by the arc-shaped dynamic clamp, the arc-shaped static clamp and the arc-shaped rubber clamp. The other end is connected to the discharge pipe of the large equipment hydraulic system.

[0031] The oil mist liquefier is mainly made of stainless steel and has a cylindrical shape. A plurality of through holes are arranged on the cylindrical surface of the oil spray end. Its main function is to discharge the high-pressure hydraulic oil into a designated container for secondary diversion to prevent the oil from being over-pressured in the container due to the cluster spraying.

[0032] The explosion-proof steel wire hose is composed of a rubber hose with a built-in steel wire explosion-proof net, an outer diameter of 35mm, an inner diameter of 31mm, high pressure resistance, and oil corrosion resistance. Two hoses are set in this equipment. Its main function is to effectively connect the reducer adapter, the integrated signal follower collector and the oil mist liquefier through a clamp, and to guide the high-pressure hydraulic oil from the large equipment to the designated container to prevent the oil from spraying and atomizing everywhere;

[0033] The clamp is made of metal material. This device is equipped with four of them. Its main function is to lock the connection between the two ends of the two explosion-proof steel wire hoses and the reducer adapter, the oil mist liquefier and the integrated signal follower collector.

[0034] The method of using the high-pressure oil rapid discharge diversion device of the hydraulic system of large equipment is as follows:

[0035] Step 1: The operator confirms that the work site has the working conditions required for the functional commissioning and testing of the hydraulic system of large equipment;

[0036] Step 2: The operator takes out the high-pressure oil rapid discharge diversion device of the hydraulic system of the large equipment in the work vehicle and checks the integrity of the equipment;

[0037] Step 3: The operator adjusts the locking nut to enlarge the middle circular area formed by the two arc-shaped rubber clamps clamped by the arc-shaped dynamic clamping plate and the arc-shaped static clamping plate, and then inserts the reducer adapter into the middle area and extends the reducer adapter to a certain length. Finally, the locking nut is adjusted to reduce the middle circular area of ​​the two arc-shaped rubber clamps through the arc-shaped dynamic clamping plate and the arc-shaped static clamping plate, and then the reducer adapter is clamped on the inner side of the arc of the arc-shaped rubber clamp;

[0038] Step 4: The operator loosens the fastening nut on one side of the stop pin until the stop pin is disengaged from the square slot of the stop rod, then rotates the telescopic positioning screw to a suitable length, and finally adjusts the fastening nut to lock the stop pin into the square slot of the stop rod and lock it;

[0039] Step 5: The operator separates the suction cup tightening handle from the handle support arm on the suction cup base, puts the interface end of the reducer adapter on the oil discharge pipe outlet of the large equipment, and makes its end face close to the discharge pipe outlet extending out of the structural plane of the large equipment;

[0040] Step 6: The operator places the rubber suction cup close to the plane structure of the large equipment, and then tightens the suction cup handle to merge it towards the handle arm on the suction cup base, so that the rubber suction cup is tightly attached to the plane structure of the large equipment;

[0041] Step 7: The operator places one end of the oil mist liquefier into the specified recovery container for the oil and covers the container with a cap;

[0042] Step 8: The operator presses the "ON / OFF" power button on the integrated signal follower collector to turn on the integrated signal follower collector. After the self-check of the integrated signal follower collector is completed, press the "ZERO" button on the integrated signal follower collector to clear all its data (time, pressure, flow, etc.);

[0043] Step 9: The operator operates a certain oil discharge "switch" on the large equipment, so that the high-pressure oil in the pipeline passes through the reducer adapter connected to the discharge pipe port, the explosion-proof steel hose, the oil mist liquefier and the integrated signal follower collector, and finally is discharged into the specified recovery container for the oil;

[0044] Step 10: The operator observes the pressure and flow values ​​on the integrated signal follower collector. When the real-time pressure value P1-0Mp and the real-time flow value Q1-0L / min, it means that the high-pressure oil in the relevant pipelines of the large equipment has been discharged;

[0045] Step 11: The operator records Pmax (maximum pressure value), Qmax (maximum flow value), Tp (the total time for the oil discharge pressure to rise from "zero" to Pmax and then drop to "zero"), and Tq (the total time for the oil discharge flow to rise from "zero" to Qmax and then drop to "zero") on the LCD screen of the integrated signal follower collector. By recording the four values ​​of Pmax, Qmax, Tp, and Tq, it is determined whether all values ​​meet the specified requirements, and then the integrity of the pipeline seal involved in the functional debugging of the hydraulic system of the large equipment is determined. If the values ​​do not meet the requirements, the operator is required to check the connection of the relevant pipelines of the hydraulic system of the large equipment and whether there are leaks and faults in the hydraulic finished products until the fault is eliminated;

[0046] Step 12: The operator presses the "0N / OFF" power button on the integrated signal follower collector to shut down the integrated signal follower collector, then separates the suction cup tightening handle from the handle support arm on the suction cup base, and then separates the reducer adapter from the discharge pipe of the large equipment, finally wipes the entire device clean and protects the exposed ports;

[0047] Step 13: The operator stores the entire removed equipment at the designated location, and the work is completed.

[0048] Beneficial effects of the present invention:

[0049] (1) The mechanical structure of the patent of the present invention is novel. By adopting a device and an operating method that integrates the functions of a plane installation and a fast oil diversion device, it completely solves the many difficult problems caused by the direct discharge of high-pressure oil into the working environment during the current functional debugging and inspection of the hydraulic system of large equipment.

[0050] (2) The invention patent adopts a connecting pin 18, a suction cup base 12, a rubber suction cup 15, a square tightening device 16 and a suction cup tightening handle 17 to form a suction cup device structure, which completely solves the difficult problem that the discharge pipe outlet of high-pressure oil is located on the plane structure of large equipment and cannot be fixed using conventional devices. In addition, the suction cup device is simple to operate, easy to maintain, and has a high reuse rate, which greatly reduces the difficulty of operation.

[0051] (3) This invention patent adopts a reducer adapter 20, a clamp 23, an explosion-proof steel hose 22, an oil mist liquefier 21 and an integrated signal follower collector 19 to form a diversion device, which can quickly divert all high-pressure oil into a specified container, replacing the previous use of a large amount of oil-absorbing cotton and sawdust powder to clean up the discharged hydraulic oil, which brings about the heavy work and increased manufacturing costs, thereby achieving "cost reduction and efficiency improvement".

[0052] (4) One of the most important "highlights" of this invention patent is that the whole equipment has a very fast flow speed for high-pressure oil. Neither the discharged oil nor the generated oil mist will leak out, thus preventing the oil mist generated by the instantaneous discharge of high-pressure oil from polluting the working environment air and affecting the health of the operator. At the same time, while ensuring that each process does not affect each other, the work efficiency is increased by 5 times compared with before.

[0053] (5) Another "highlight" of this invention patent is that by recording the four values ​​of Pmax, Qmax, Tp, and Tq and comparing them with the specified values ​​of the debugging requirements, the operator can quickly determine whether the pipeline sealing and hydraulic finished products involved in the functional debugging and testing of the hydraulic system of large equipment are intact, thereby improving work efficiency.

[0091] Embodiment 2:

[0092] The method of using the high-pressure oil rapid discharge diversion device of the hydraulic system of large equipment is as follows:

[0093] Step 1: The operator confirms that the work site has the working conditions required for the functional commissioning and testing of the hydraulic system of large equipment;

[0094] Step 2: The operator takes out the high-pressure oil rapid discharge diversion device of the hydraulic system of the large equipment in the work vehicle and checks the integrity of the equipment;

[0095] Step 3: The operator adjusts the locking nut 7 to enlarge the middle circular area formed by the two arc-shaped rubber clamps 3 clamped by the arc-shaped dynamic clamp plate 2 and the arc-shaped static clamp plate 1, and then inserts the reducer adapter 20 into the middle area and extends the reducer adapter 20 to a certain length, and finally adjusts the locking nut 7 to reduce the middle circular area of ​​the two arc-shaped rubber clamps 3 through the arc-shaped dynamic clamp plate 2 and the arc-shaped static clamp plate 1, and then clamps the reducer adapter 20 on the inner side of the arc of the arc-shaped rubber clamp 3;

[0096] Step 4: The operator loosens the fastening nut 10 on one side of the stop pin 11 until the stop pin 11 is disengaged from the square slot of the stop rod 13, then rotates the telescopic positioning screw 9 to a suitable length, and finally adjusts the fastening nut 10 to clamp the stop pin 11 in the square slot of the stop rod 13 and lock it;

[0097] Step 5: The operator separates the suction cup tightening handle 17 from the handle support arm on the suction cup base 12, and puts the interface end of the reducer adapter 20 on the oil discharge pipe outlet of the large equipment, and makes its end face close to the structural plane of the discharge pipe outlet extending out of the large equipment;

[0098] Step 6: The operator places the rubber suction cup 15 tightly against the plane structure of the large equipment, and then merges the suction cup tightening handle 17 toward the handle support arm on the suction cup base 12, so that the rubber suction cup 15 is tightly adsorbed on the plane structure of the large equipment;

[0101] Step 9: The operator operates a certain function oil discharge "switch" on the large equipment, so that the high-pressure oil in the pipeline passes through the reducer adapter 20 connected to the discharge pipe port, the explosion-proof steel wire hose 22, the oil mist liquefier 21 and the comprehensive signal follower collector 19, and finally is discharged into the specified recovery container for the oil;

[0102] Step 10: The operator observes the pressure and flow values ​​on the integrated signal follower collector 19. When the real-time pressure value P1-0Mp and the real-time flow value Q1-0L / min, it indicates that the high-pressure oil in the relevant pipelines of the large equipment has been discharged;

[0103] Step 11: The operator records Pmax (maximum pressure value), Qmax (maximum flow value), Tp (the total time for the oil discharge pressure to rise from "zero" to Pmax and then drop to "zero"), and Tq (the total time for the oil discharge flow to rise from "zero" to Qmax and then drop to "zero") on the LCD screen of the integrated signal follower collector 19. By recording the four values ​​of Pmax, Qmax, Tp, and Tq, it is determined whether all values ​​meet the specified requirements, and then the integrity of the pipeline seal involved in the functional debugging of the hydraulic system of the large equipment is determined. If the values ​​do not meet the requirements, the operator is required to check the connection of the relevant pipelines of the hydraulic system of the large equipment and whether there are leaks and faults in the hydraulic finished products until the fault is eliminated;

[0104] Step 12: The operator presses the "ON / OFF" power button on the integrated signal follower collector 19 to turn off the integrated signal follower collector 19, and then separates the suction cup tightening handle 17 from the handle support arm on the suction cup base 12, and then separates the reducer adapter 20 from the discharge pipe of the large equipment, and finally wipes the entire equipment clean and protects the exposed ports;

[0105] Step 13: The operator stores the entire removed equipment at the designated location, and the work is completed.
