Description

Technical Field

[0001] The present invention relates to the field of tractor hydraulic detection equipment, and specifically to a performance detection connection device and a detection system for a multi-way hydraulic output system of a tractor. Background Technique

[0002] Hydraulic output is an important function of a tractor. Relevant standards, agricultural machinery promotion and appraisal outlines, etc. all have higher requirements for it. Especially for detection equipment, it is related to the product design and R & D capabilities, in-line inspection capabilities, and thus affects the product quality and reliability. Therefore, it can be said that the information-based testing system for the performance of the multi-way hydraulic output device will be an essential equipment for relevant enterprises, institutions, and companies.

[0003] Regarding the hydraulic output device, it is actually one of the key components of a tractor.

Facing the development needs of large-horsepower and intelligent tractors, the demand for a testing system for the multi-way output device and an information-based testing system is more urgent. During the connection of pipelines, since multiple groups of pipelines are set, all these pipelines need to be connected to the testing device. If there are multiple leaks during the test, they need to be repaired one by one, which is very time-consuming.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0045] Please refer to Figures 1 to 11 , taking the setting of four-way hydraulic output pipelines as an example, the present invention provides a technical solution: a performance detection connection device for a tractor multi-way hydraulic output system. In this device, the "multi-way" refers to no less than three groups of oil circuits (including three groups), including a horizontal translation mechanism 1 and a vertical translation mechanism 2. The horizontal translation mechanism 1 is slidably connected to the vertical translation mechanism 2, and the vertical translation mechanism 2 can be driven by the horizontal translation mechanism 1 to move back and forth. A seat plate 3 is connected to the vertical translation mechanism 2. An elevation assembly 4 is provided on the seat plate 3. A fine-tuning slide rail 5 is provided on the elevation assembly 4. An installation plate 6 is slidably connected to the fine-tuning slide rail 5. The installation plate 6 is a bent structure with different heights at both ends. A first bracket assembly 61 and a second bracket assembly 62 are respectively provided at the two ends with different heights on the installation plate 6. Two clamping assemblies 7 are provided on the installation plate 6. A baffle plate assembly 8 is provided between the two clamping assemblies 7. The two clamping assemblies 7 are respectively used to clamp the hydraulic connectors on the tractor 100 and the detection box 200. The baffle plate assembly 8 can ensure that the two clamping assemblies 7 maintain the same height. A pipe fitting cleaning assembly 9 is also provided on the installation plate 6. The pipe fitting cleaning assembly 9 is used to clean the dust on the hydraulic pipelines of the tractor 100. A leak prevention device 10 is also provided between the clamping assemblies 7. The leak prevention device 10 is installed on the installation plate 6. The leak prevention device 10 is used to prevent leakage from occurring after the hydraulic connectors on the tractor 100 and the detection box 200 are connected. The pipelines cleaned by the pipe fitting cleaning assembly 9 are more convenient for connection. The above-mentioned clamping assemblies 7, baffle plate assembly 8, pipe fitting cleaning assembly 9 and leak prevention device 10 can be set with the same quantity and position corresponding to the quantity and position of the oil circuit groups.

[0046] In this embodiment, the air lifting assembly 4 includes a power assembly 41 at the bottom, a threaded rod 42, a guide rod 43, and a top plate 44. The power assembly 41 is a reduction motor. The threaded rod 42 is connected to the power assembly 41. The upper end of the threaded rod 42 is connected inside the top plate 44 and can drive the top plate 44 to move up and down by the rotation of the threaded rod 42. The guide rod 43 is located below the four corners of the top plate 44. The seat plate 3 is provided with through holes for the guide rod 43 to move downward. By driving the threaded rod 42 to rotate through the power assembly 41, the up and down movement of the top plate 44 can be realized, and then the clamping assembly 7 can be driven to move up and down, which is convenient for finding the position and connecting the oil pipe.

[0047] In this embodiment, the fine-tuning slide rail 5 is an electric slide rail controlled by remote control. Through the movement control of external inspectors, the position of the mounting plate 6 can be finely adjusted, which is convenient for connecting the rigid oil circuit connectors at both ends.

[0048] In this embodiment, the first bracket assembly 61 includes a backing plate 611, a triangular connecting plate 612, and a connecting seat 613. The backing plate 611 is fixed on the mounting plate 6. The triangular connecting plate 612 is fixed on the backing plate 611. The connecting seat 613 is fixed on the side surface of the triangular connecting plate 612. Through the first bracket assembly 61, the clamping assembly for the oil circuit connector on the clamping and detecting box 200 can be fixedly connected to the mounting plate 6. At the same time, the clamping assembly 7 here has a fixed height.

[0049] In this embodiment, the second bracket assembly 62 includes a bracket lifting motor 621, a screw rod 622, an upper cover 623, a support frame 624, a bracket shaft 625, and a slide rail 626. The bracket lifting motor 621 is installed below the mounting plate 6 and its output shaft is connected to the bottom of the screw rod 622. The upper end of the screw rod 622 is connected to a connecting plate 6231 inside the upper cover 623 and can drive the upper cover 623 to move up and down by rotation. A slider 627 is provided on the inner side surface of the vertical side wall of the connecting plate 6231. The slider 627 is slidably connected inside the slide rail 626. The bottom of the slide rail 626 is fixed on a slide rail seat plate 628, and the slide rail seat plate 628 is installed on the mounting plate 6. The support frame 624 is installed on the top of the upper cover 623. A slidable bracket shaft 625 is installed inside the support frame 624. A cylinder 629 is also provided on the support frame 624. The output shaft of the cylinder 629 is connected to the bracket shaft 625 through a connecting plate. Through the second bracket assembly 62, the clamping assembly 7 for the oil circuit connector on the tractor 100 can be fixedly connected to the mounting plate 6. At the same time, since a lifting motor 621 and a slide rail 626 are provided below the clamping assembly 7 on this side, on the premise of adjusting the clamping assemblies 7 on both sides together through the mounting plate 6, the clamping assembly 7 at this position can be adjusted separately to achieve precise clamping of the oil circuit connector on the tractor 100.

[0050] In this embodiment, the clamping assembly 7 includes symmetrically arranged jaws 71, jaw seats 72 and an opening and closing cylinder 73. The bottom of the jaw 71 is mounted on the jaw seat 72 through a rotating shaft 74. A force-receiving block 75 is provided on the middle side of the jaw 71. The side of the force-receiving block 75 is connected to the output shaft of the opening and closing cylinder 73. A cylinder frame 76 is provided at the bottom of the opening and closing cylinder 73. The cylinder frame 76 is mounted on the mounting plate 6. The oil circuit connectors on the tractor 100 and the detection box 200 are placed in the jaws 71, and the opening and closing cylinder 73 is controlled to clamp the oil circuit connectors. Here, the control of the opening and closing cylinder 73 can be manually controlled or electrically controlled by using a sensor to detect the oil circuit connectors.

[0051] In this embodiment, the jaw seats 72 are respectively mounted on the connecting seat 613 and the support shaft 625. The two side jaw seats 72 are respectively mounted, which is convenient for adjusting the respective clamping assemblies 7.

[0052] In this embodiment, the blocking plate assembly 8 includes a component base 81, an airbag 82, a blocking plate 83, a return spring 84 and a spring shaft 85. The component base 81 is mounted on the jaw seat 72. The airbag 82 is mounted on the top of the component base 81 and is located between the two jaws 71. The blocking plate 83 is mounted on the component base 81. The spring shaft 85 passes through the blocking plate 83 and is mounted on the side of the component base 81. The return spring 84 is mounted on the spring shaft 85. A blocking hole 86 for the blocking plate 83 to pass through is provided on the other jaw seat 72 symmetric to the jaw seat 72 on which the component base 81 is mounted. The bottom surface of the blocking plate 83 is at the same height as the bottom surface of the blocking hole 86. After the oil circuit connectors are respectively clamped by the clamping assemblies 7 on both sides, the clamping assembly 7 that clamps the oil circuit connector on the tractor 100 is driven by the lifting motor 621 to move up and down. Since the airbag 82 will be compressed when the jaws 71 are closed, the blocking plate 83 will protrude. When the clamping assembly 7 on the opposite side moves up and down to adjust the position, the blocking plate 83 will be inserted into the blocking hole 86, so that the positions of the clamping assemblies 7 on both sides are fixed. At this time, the oil circuit connectors on both sides are on the same horizontal line. The cylinder 629 is used to drive the oil circuit connector on the tractor 100 to move inward. Since the oil circuit connectors used are generally quick-insert type, the two oil circuit connectors will be inserted into the outlets on both sides of the cross valve 103 under the push of the cylinder 629 and are connected in the cross valve 103.

[0053] In this embodiment, the pipe fitting cleaning assembly 9 includes a cleaning motor 91, a limiting plate 92, a pulley set 93, a cleaning ring 94, a friction ring 95 and a rotating ring 96. The cleaning motor 91 is connected to the pulley set 93. The cleaning motor 91, the limiting plate 92 and the pulley set 93 are installed on the support frame 624 through a bent plate 97. A limiting ring 921 is provided above the limiting plate 92. Both the cleaning ring 94 and the friction ring 95 rotate within the limiting ring 921. The cleaning ring 94 and the friction ring 95 are both installed on the rotating ring 96. The rotating ring 96 is located at the top of the pulley set 93 and its bottom is clamped within a clamping block 98. The clamping block 98 is fixed to the top of the bent plate 97. During the process of clamping the oil circuit connector on the tractor 100, since the oil circuit pipes on the tractor 100 are often dirty, when these oil circuit pipes extend into the limiting ring 921 at the top of the limiting plate 92, the dirt on their surfaces will be cleaned by the continuously rotating cleaning ring 94 and friction ring 95, which facilitates the connection of the oil circuit connector.

[0054] The anti-leakage device 10 includes an upright frame 101, fixed clamping plates 102, a cross valve 103, a spherical liquid storage chamber 104, and a pressurizing device 105. The cross valve 103 is fixed within the fixed clamping plates 102, the fixed clamping plates 102 are fixed to the upright frame 101, the spherical liquid storage chamber 104 is fixedly connected to the bottom outlet of the cross valve 103, both ends of the spherical liquid storage chamber 104 are connected to a bracket through elastic columns. A clamping block 106 is provided below the spherical liquid storage chamber 104, and the clamping block 106 is connected to a variable resistor. Here, a sliding rheostat is selected as the variable resistor. The sliding of the clamping block 106 on the variable resistor will change the resistance value of the variable resistor, thereby achieving a change in current. The variable resistor is electrically connected to the pressurizing device 105 through a connecting plate, and the pressurizing device 105 changes the air pressure within the cross valve 103 according to the change in the resistance value of the variable resistor; The pressurizing device 105 includes an outer cylinder 1051, an inner cylinder 1052, an electric push rod 1053, and a connecting ring 1054. The outer cylinder 1051 is fixed within the fixed clamping plates 102, the inner cylinder 1052 is fixedly connected to the inner wall of the outer cylinder 1051 through the connecting ring 1054, the top of the electric push rod 1053 is fixed to the outer cylinder 1051, the output shaft of the electric push rod 1053 is connected to a piston, and the piston is slidably connected to the inner wall of the inner cylinder 1052. The electric push rod 1053 is electrically connected to the connecting plate. When leakage occurs at the oil circuit joint, the falling hydraulic oil will enter the spherical liquid storage chamber 104 through the cross valve 103. The weight of the spherical liquid storage chamber 104 increases, compressing the elastic columns at both ends to reduce the height of the spherical liquid storage chamber 104. When descending, the relative sliding between the clamping block 106 and the variable resistor changes the resistance value and current magnitude of the variable resistor. Since the variable resistor is electrically connected to the electric push rod 1053 through a connecting plate, the increased current will cause the output shaft of the electric push rod 1053 to extend more, pressing down the piston within the inner cylinder 1052 to increase the air pressure within the cross valve 103. By pressurizing the outside of the oil circuit joint, the oil pressure within the hydraulic joint is balanced. When the external air pressure is greater than the oil pressure, the oil will no longer leak until the weight of the spherical liquid storage chamber 104 no longer increases, and the fact that the weight of the spherical liquid storage chamber 104 no longer increases indicates that the hydraulic oil no longer leaks.

[0055] Sealing ports with the same outer diameter as the oil circuit joint are provided at the valve ports on the left and right sides of the provided cross valve 103, and sealing gaskets are provided within the sealing ports, which can make the interior of the cross valve 103 a sealed environment after the oil circuit joint is inserted.

[0056] The working principle of the above device is as follows:

[0057] During detection, since the tractor needs to be driven into the detection workshop from the outside and parked near the detection box 200, the stopping positions of the tractors 100 may not be exactly the same for each vehicle and each time. Therefore, it is necessary to adjust the position of the entire connection device through the lateral translation mechanism 1 and the longitudinal translation mechanism 2 to make the connection device as close as possible to the tractors 100 and the detection box 200. Then, the oil circuit connector on the detection box 200 connected by a hose is manually placed on the clamping assembly 7 without the pipeline cleaning assembly 9 and clamped by the clamp 71. Then, the positions of the two groups of clamping assemblies 7 are adjusted through the fine-tuning slide rail 5 so that the clamping assembly 7 clamping the oil circuit connector on the tractor 100 can correctly clamp the oil circuit connector. At the same time, the vertical position of the clamping assembly 7 here is adjusted until the oil circuit connector on the tractor 100 is clamped. After clamping, the clamping assembly 7 clamping the oil circuit connector on the tractor 100 is driven by the lifting motor 621 to move up and down. Since the airbag 82 will be compressed when the clamp 71 closes, the blocking plate 83 will protrude. When the clamping assembly 7 on the opposite side moves up and down to adjust the position, the blocking plate 83 will insert into the blocking hole 86 to fix the positions of the two clamping assemblies 7. At this time, the oil circuit connectors on both sides are on the same horizontal line. The cylinder 629 is used to drive the oil circuit connector on the tractor 100 to move inward. Since the oil circuit connectors used are generally quick-connect types, the two oil circuit connectors will be connected under the push of the cylinder 629. Then, all the oil circuit connectors can be connected in sequence according to this operation. After the connection is completed, when there is a leak at the oil circuit connector, the dropped hydraulic oil will enter the spherical liquid storage bin 104 through the cross valve 103. The weight of the spherical liquid storage bin 104 increases, compressing the elastic columns at both ends to reduce the height of the spherical liquid storage bin 104. When it descends, the relative sliding of the block 106 and the rheostat changes the resistance value and current magnitude on the rheostat. Since the rheostat is electrically connected to the electric push rod 1053 through the connecting plate, the increased current will make the output shaft of the electric push rod 1053 extend more, pressing the piston in the inner cylinder 1052 to increase the air pressure in the cross valve 103. By pressurizing the outside of the oil circuit connector, the oil pressure inside the hydraulic connector is balanced. When the external air pressure is greater than the oil pressure, the oil will no longer leak until the weight of the spherical liquid storage bin 104 no longer increases. And the fact that the weight of the spherical liquid storage bin 104 no longer increases means that the hydraulic oil no longer leaks.

[0058] The present invention also discloses a detection system using the above-mentioned detection connection device for the performance of the tractor multi-way hydraulic output system. Refer to the attached Figure 8: It includes a tractor 100 and a detection box 200. The multiple pipelines and connectors on the tractor 100 and the detection box 200 are butted after being clamped by a clamping assembly 7. The hydraulic oil in the tractor 100 flows into the detection box 200. After measuring the pressure, temperature, and flow rate data, the data is stored in a data collector. The collector processes the data in real time and transmits it to a control system. The control system outputs control instructions to a hydraulic system according to the running program or manually input parameters, controls the opening degree of an electro-hydraulic proportional valve, and thus controls the hydraulic output flow rate of the tractor. The control system records and displays key data in real time until the entire detection program is completed.

[0059] Based on the above, the novel hydraulic pipeline connection device of the present invention can meet the rapid connection of multiple pipelines, save manpower, and avoid the phenomena of wrong connection and leakage.

[0060] As is known by technical common sense, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
