Description

Technical Field

[0001] This utility model relates to the field of hydraulic motor testing, and in particular to a test platform for hydraulic motor outlet pressure fluctuation. Background Technology

[0002] In hydraulic systems, the hydraulic motor, as a key actuator that converts hydraulic energy into mechanical energy, directly affects the operational stability and efficiency of the equipment due to fluctuations in its outlet pressure. Therefore, accurate detection and analysis of hydraulic motor outlet pressure fluctuations are crucial for ensuring the reliable performance of the hydraulic motor and guaranteeing the normal operation of the hydraulic system.

[0003] Currently, existing hydraulic motor outlet pressure fluctuation test platforms have some shortcomings in practical use. Regarding pipeline connections, some test platforms employ connection methods with poor stability. Hydraulic connecting pipes are directly suspended on the test platform, and when the pipe ends are inserted downwards into the corresponding inlet / outlet ports, the pipe neck is bent. During testing, this can easily lead to excessive bending, shaking, or even loosening of the pipeline. This not only affects the accuracy of pressure test data but may also cause hydraulic oil leakage, posing certain safety hazards. Furthermore, it is not conducive to pipeline storage and management.

[0004] Therefore, it is necessary to provide a new test platform for hydraulic motor outlet pressure fluctuations to solve the above-mentioned technical problems. Utility Model Content

[0013] 1. This utility model uses a curved guide tube on the plate base to assist the hydraulic connecting pipe in docking, and adopts an electromagnetically controlled clamp locking structure. During docking, the electromagnet attracts the magnetic plate to unlock the clamp, which facilitates the quick docking of the hydraulic connecting pipe with the inlet and outlet of the hydraulic motor. After use, the spring resets the hydraulic connecting pipe to lock it in place quickly with the curved guide tube. Combined with the guiding protection of the pipeline by the curved guide tube, it can prevent the hydraulic connecting pipe from bending and shaking, ensuring the stability and sealing of the pipeline connection during the test.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A test platform for hydraulic motor outlet pressure fluctuation includes: a test bench 1, a pressure fluctuation detection component 2 on the test bench 1, a controller 21 on the outside of the pressure fluctuation detection component 2, hydraulic connecting pipes 22 symmetrically arranged on the test bench 1, and a mounting base 3 at one end of the test bench 1; an auxiliary pipe placement mechanism, including a plate base 4, curved guide pipes 41 at both ends of the plate base 4, two hydraulic connecting pipes 22 respectively arranged in the two curved guide pipes 41, a rear frame 42 fixedly connected to the test bench 1, and an adjustment component on the rear frame 42.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the adjustment assembly includes a vertical rod 43, which is fixedly connected to a rear frame 42. An adjustment shaft 44 is rotatably connected to the rear frame 42. One end of the plate base 4 is slidably connected to the vertical rod 43. A motor 45 is installed and connected to the top of the rear frame 42. The output end of the motor 45 is fixedly connected to the adjustment shaft 44.

[0023] It should be noted that the curved guide tube 41 is used to guide and protect the hydraulic connection tube 22, which effectively prevents it from being excessively bent or shaking after installation, and also makes it easier to store and use.

[0024] The vertical rod 43 is fixedly connected to the rear frame 42, providing precise guidance for the sliding of the plate base 4 and ensuring that it remains stable during height adjustment without moving. The rear frame 42 is rotatably connected to the adjustment shaft 44, which controls the output of the motor 45 to rotate forward and backward, and can precisely and quickly drive the adjustment shaft 44 to rotate, thereby realizing the up and down movement of the plate base 4 along the vertical rod 43, and realizing the adjustment of the usage position of the curved guide tube 41.

[0025] refer to Figure 2 As shown, the adjusting shaft 44 is a threaded rod, and the other end of the plate base 4 is provided with a threaded opening. The other end of the plate base 4 is threadedly connected to the adjusting shaft 44.

[0026] refer to Figure 2 and Figure 3 As shown, an ear ring 5 is installed at the head of the hydraulic connecting pipe 22. Both ends of the ear ring 5 are provided with inserts 51. Two alignment seats 52 are symmetrically provided at the opening of the curved guide pipe 41. Each of the two alignment seats 52 is provided with an alignment groove. The two inserts 51 are slidably connected to the two alignment grooves respectively.

[0027] It should be noted that the lug 5 and insert 51 installed at the pipe head of the hydraulic connecting pipe 22 form a precise positioning connection structure with the alignment seat 52 and alignment groove at the pipe opening of the curved guide pipe 41. In actual operation, when the hydraulic connecting pipe 22 is directly inserted into the curved guide pipe 41, the insert 51 slides along the alignment groove to perform a preliminary positioning function, ensuring that the hydraulic connecting pipe 22 can be quickly matched with the curved guide pipe 41 after being retracted and placed, making it convenient for storage.

[0028] refer to Figure 3 and Figure 4 As shown, locking grooves are provided on the side walls of the two inserts 51, and hidden grooves are provided in the two alignment seats 52. The two hidden grooves are connected to one end of the two alignment grooves respectively, and side tubes 6 are fixedly connected to the openings of the two hidden grooves.

[0029] refer to Figure 3 and Figure 4 As shown, a slide rod 7 is slidably connected to one end of the side tube 6. A clamp 71 is fixedly connected to one end of the slide rod 7. The clamp 71 is a wedge-shaped head. A magnetic plate 72 is fixedly connected to the other end of the slide rod 7. A spring 73 is sleeved and connected to the slide rod 7. An electromagnet 74 is installed and connected to the inner wall of one end of the side tube 6. The magnetic poles of the electromagnet 74 and the magnetic plate 72 are opposite. Limiting protrusions 8 are provided on both ends of the side wall of the magnetic plate 72. Two limiting grooves are symmetrically provided on the inner wall of the side tube 6. The two limiting protrusions 8 are slidably connected to the two limiting grooves respectively.

[0030] It should be noted that: after the electromagnet 74 is energized, the electromagnetic force generated attracts the magnetic plate 72, which drives the slide rod 7 and the chuck 71 to slide into the side tube 6 against the elastic force of the spring 73, causing the chuck 71 to retract and exit the locking groove. At this time, the hydraulic connecting pipe 22 can move freely to connect with the hydraulic motor during testing.

[0031] The cooperation between the limiting protrusion 8 and the limiting groove effectively restricts the movement direction of the magnetic plate 72, preventing it from shifting or rotating during movement.

[0032] When the electromagnet 74 is de-energized, the spring 73 returns to its elastic deformation, pushing the magnetic plate 72, the slide bar 7 and the clamp 71 to move in the opposite direction. Due to the wedge-shaped design of the clamp 71, during the insertion of the insert 51, the clamp 71 will automatically slide into the locking groove to achieve a firm lock on the hydraulic connecting pipe 22, ensuring its stable storage and locking.

[0033] The working principle of the hydraulic motor outlet pressure fluctuation test platform provided by this utility model is as follows: the hydraulic motor under test is connected to the system using two hydraulic connecting pipes 22, and the pressure fluctuation detection component 2 is used to collect the motor outlet pressure data to monitor the pressure change of the hydraulic motor outlet in real time.

[0034] According to the specifications of the hydraulic motor under test, start motor 45 adjusts the height of plate base 4 so that curved guide tube 41 is aligned with the motor outlet interface. Start motor 45 drives adjustment shaft 44 (threaded rod) to rotate. Since the threaded port of plate base 4 is threadedly engaged with adjustment shaft 44 and the other end of plate base 4 is slidably connected to vertical rod 43, plate base 4 will move up and down along vertical rod 43. The movement of plate base 4 drives the two curved guide tubes 41 to move synchronously, thereby adjusting the height and angle of hydraulic connecting pipe 22 extending from curved guide tube 41 to adapt to the installation of hydraulic motors of different specifications. This allows hydraulic connecting pipe 22 to adapt to the hydraulic motor interface at different installation positions in real time.

[0035] When docking is required, the two electromagnets 74 are energized, causing them to magnetically attract the two magnetic plates 72 to move. The magnetic plates 72 overcome the elastic force of the spring 73, driving the slide rod 7 and the clamp 71 to slide into the side tube 6. The clamp 71 exits the locking groove, at which point the insert 51 can slide freely, directly pulling the hydraulic connecting pipe 22 so that it slides relative to the opening of the curved guide tube 41, which can facilitate docking with the inlet and outlet of the hydraulic motor. When not in use, the electromagnets 74 are de-energized, and then the two inserts 51 are slidably inserted into the two positioning seats 52 respectively. Due to the wedge-shaped setting of the clamp 71, the clamp 71 can drive the slide rod 7 to slide relative to the side tube 6 until the insert 51 is fully inserted. The spring 73 restores its elastic deformation, causing the clamp 71 to move in the opposite direction and return to the locking groove. This conveniently achieves the placement and limiting of the hydraulic connecting pipe 22. With the curved guide tube 41 used to guide and protect the hydraulic connecting pipe 22, it effectively avoids bending and shaking, and is also easy to store and use.
