Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic station technology, and in particular to a quick disassembly and assembly device for a bottom-mounted hydraulic station. Background Technology
[0002] A hydraulic power unit, also known as a hydraulic pump station, is an independent hydraulic power unit that can supply oil according to staged requirements and control the direction, pressure, and flow rate of hydraulic oil. It is suitable for various hydraulic machinery. Hydraulic power units generally come in various structural forms, including integral, side-mounted, top-mounted, bottom-mounted, cabinet-type, or other structural forms. Often, due to space constraints in the fixed location of the hydraulic power unit, a bottom-mounted hydraulic power unit is frequently used to further reduce its footprint.
[0003] Bottom-mounted hydraulic power units typically have a compact structural design and the advantages of small footprint and suitability for installation environments with limited space, thus gaining widespread application.
[0004] To effectively improve the suction performance of the hydraulic pump, a bottom-mounted hydraulic power unit places the hydraulic oil tank above the electric motor. While this design effectively improves the pump's suction performance, in the event of a motor failure, the limited vertical space makes it difficult for maintenance personnel to easily access and repair the motor located below the hydraulic oil tank. This means that when the motor needs repair, the hydraulic oil tank must first be removed, and then each component of the bottom-mounted hydraulic power unit must be disassembled manually using hand tools before the motor can be removed and repaired.
[0005] This method not only involves a large workload, but also a complicated disassembly process and low efficiency. In addition, after the repair, the motor must be installed first, and then the hydraulic oil tank located on top of the motor must be installed.
[0006] Therefore, the traditional bottom-mounted hydraulic station structure is not conducive to convenient maintenance of the electric motor. There is an urgent need to provide a quick disassembly and assembly device for the motor of the bottom-mounted hydraulic station to effectively improve the maintenance inconvenience caused by the traditional motor installation method. Utility Model Content
[0007] The technical problem to be solved by this utility model is: in order to solve the technical problem of inconvenient disassembly and assembly of the motor of the bottom-mounted hydraulic station in the prior art, this utility model provides a quick disassembly and assembly device for the bottom-mounted hydraulic station. It adopts a sliding support and a strip slide rail to realize the convenient change of the position of the motor. At the same time, each pair of roller assemblies has a limiting fit relationship with the two strip slide rails to ensure that it does not deviate from the predetermined trajectory during the sliding process.
[0008] The technical solution adopted by this utility model to solve its technical problem is: a quick-release device for a bottom-mounted hydraulic station, which is installed on the hydraulic station. The hydraulic station includes a support base and a hydraulic oil tank and an electric motor installed on the support base. It includes a quick-release mechanism, which is located between the support base and the electric motor. A motor mounting space for accommodating the electric motor is provided between the support base and the hydraulic oil tank. The electric motor and the support base are slidably connected through the quick-release mechanism, so that the electric motor can enter or leave the motor mounting space. The quick-release mechanism can lock or release the electric motor relative to the support base.
[0009] This utility model discloses a quick-assembly and disassembly device for a bottom-mounted hydraulic power unit. The motor can move on a support base, allowing it to be moved into the motor's working space during operation and locked to the support base, reducing the possibility of slippage. When maintenance is required, the motor can be moved out of the working space for easy access. This solution effectively changes the traditional installation method of the motor in a bottom-mounted hydraulic power unit. During motor maintenance, it eliminates the need to disassemble each component of the hydraulic power unit individually, and after maintenance, it eliminates the need to reassemble each component. This significantly improves motor maintenance efficiency, effectively reduces the workload of operators, and helps ensure the operational efficiency of the bottom-mounted hydraulic power unit.
[0010] Furthermore, the quick-release mechanism includes a sliding support and a locking assembly. The sliding support is connected to the motor, and the locking assembly is connected to the sliding support and is used to lock or release the sliding support to the support base when the motor is located in the motor mounting space.
[0011] The above technical solution utilizes a locking assembly to lock or release the sliding support from the base, reducing the possibility of the motor sliding between itself and the base during operation.
[0012] Furthermore, the support base is provided with a strip slide rail, and the sliding support slides on the strip slide rail.
[0013] The above technical solution provides a stable sliding platform for the sliding support by installing a strip rail on the upper end of the support base.
[0014] Furthermore, the sliding support is provided with a roller assembly, which cooperates with the strip rail and can drive the sliding support to move on the strip rail.
[0015] The above technical solution effectively reduces friction by utilizing the rolling engagement between the roller assembly and the strip rail. Therefore, when motor maintenance is required, the sliding support only needs to be pulled out from its normal operating position directly below the hydraulic tank to a maintenance position outside the tank. Conversely, after maintenance, the motor can be easily pushed back to its normal operating position. The rolling engagement between the sliding support and the strip rail effectively reduces the workload of maintenance personnel and facilitates the easy pulling out and pushing back of the motor.
[0016] Furthermore, the roller assembly includes a mounting frame, a pin, and a bearing. The mounting frame is connected to the sliding support, the pin is mounted on the mounting frame, the bearing is rotatably connected to the pin, and the bearing rolls on the strip rail.
[0017] Furthermore, the mounting frame is provided with a limiting section, the lowest height of which is greater than the maximum height of the strip rail, so as to limit the roller assembly and the strip rail along the Y direction.
[0018] The above technical solution utilizes the cooperation between the limiting section and the strip slide rail to ensure that the slide does not deviate from the track. At the same time, when multiple quick assembly and disassembly mechanisms are set up at the same time, there will be no mutual interference.
[0019] Furthermore, the roller assembly also includes a nut, one end of the pin is connected to a limit block, and the other end has an external thread. The end of the pin with the external thread passes through the mounting frame and is threadedly connected to the nut.
[0020] Furthermore, a spring washer is fitted onto the pin shaft, and the spring washer is located between the nut and the mounting frame.
[0021] Furthermore, the sliding support includes an upper bracket, a strip steel plate, and a shock-absorbing strip. The upper bracket is connected to the motor, the strip steel plate is connected to the roller assembly, and the shock-absorbing strip is disposed between the strip steel plate and the upper bracket.
[0022] The above technical solution uses an upper bracket to fix and support the motor, thereby achieving a reliable connection between the motor and the sliding support. The damping strip can buffer the vibration generated when the motor is working, and at the same time, the strip steel plate and the support frame have a certain buffering capacity, thus effectively protecting the motor during the sliding process.
[0023] Furthermore, the locking assembly includes a locking bolt, one end of which passes through the sliding support and can be threadedly connected to the support base. Attached Figure Description

[0032] This utility model discloses a quick assembly and disassembly device for a bottom-mounted hydraulic station.
[0033] Reference Figures 1 to 4 A quick-release device for a bottom-mounted hydraulic power unit includes multiple quick-release mechanisms 4 installed within the hydraulic power unit. The hydraulic power unit includes a support base 1, a hydraulic oil tank 2, and a motor 3. The support base 1 is horizontally positioned, extending along the X-direction. The hydraulic oil tank 2 is fixedly supported above the support base 1, with a space between the hydraulic oil tank 2 and the support base 1 for motor installation. The motor 3 is located within this space and positioned above the support base 1. The motor 3 is slidably connected to the support base 1, allowing it to enter or leave the installation space. The quick-release mechanisms 4 are used to lock or release the motor 3 relative to the support base 1.
[0034] Specifically, multiple sets of quick-release mechanisms 4 are distributed sequentially at intervals along the X direction. In this embodiment, the quick-release mechanisms 4 are preferably set to 3 sets, corresponding to three sets of motors 3. The quick-release mechanism 4 includes a strip slide rail 42 and a sliding support 41. In this embodiment, there are two strip slide rails 42, which are installed side by side on the upper end of the support base 1, and their length direction extends along the X direction. The upper surface of the strip slide rail 42 is a planar structure so that the sliding support 41 can move on the strip slide rail 42. It should be noted that the length of both strip slide rails 42 is sufficient to meet the distance for moving the motor 3 out for maintenance.
[0035] The sliding support 41 includes a support frame 411, an upper bracket 412, a strip steel plate 413, and a roller assembly 414. The support frame 411 is horizontally arranged and extends along the X direction in its length direction. The upper bracket 412 is fixedly installed on the upper end of the support frame 411 and is fixedly connected to the motor 3 to support the motor 3. Specifically, the motor 3 and the upper bracket 412 can be fixedly connected by bolts.
[0036] Two strip steel plates 413 are arranged side-by-side below both ends of the support frame 411 along its length, and are correspondingly positioned to correspond to two strip rails 42. The upper ends of the two strip steel plates 413 are fixedly connected to the lower ends of both ends of the support frame 411 along its length via two correspondingly distributed damping strips 415. To ensure damping effect and effectively save costs, the damping strips 415 can be made of rubber and steel plate.
[0037] Two pairs of roller assemblies 414 are provided, each pair being installed at the lower part of both ends of two strip steel plates 413 along their length, with each pair of roller assemblies 414 correspondingly distributed at the same end of the two strip steel plates 413. Each roller assembly 414 includes a mounting frame 4141, pins 4142, and bearings 4143. The mounting frame 4141 is formed by bending a steel plate twice at 90 degrees to create a U-shape, with its open end facing downwards. The upper end of its horizontal section is fixedly connected to the lower end of the strip steel plate 413, and a pair of mounting holes are correspondingly provided on its vertical section to allow the pins 4142 to be inserted into these holes for a limiting fit with the mounting frame 4141. In this embodiment, each pin 4142 is provided with two bearings 4143, which are arranged side-by-side in the inner cavity of the mounting frame 4141 and spaced apart from each other on the outside of the pin 4142. The bearing 4143 can be a deep groove ball bearing 4143 or a cylindrical roller bearing 4143, etc.
[0038] In addition, in each pair of roller assemblies 414, the lower end of the side arm of the two mounting frames 4141 on the opposite side has a limiting section 4144. The two limiting sections 4144 are respectively on the outside of the two strip slide rails 42, so as to limit the roller assembly 414 and the strip slide rail 42 in the Y direction and prevent the strip slide rail 42 and the roller assembly 414 from moving relative to each other in the Y direction.
[0039] The sliding support 41 is rolled on the upper end of the two strip rails 42 by two pairs of roller assemblies 414 respectively. Each pair of roller assemblies 414 is in limiting engagement with the outer ends of the two strip steel plates 413 by two limiting sections 4144, so that the sliding support 41 can move relative to the strip steel plates 413 in the X direction, but cannot move in the Y direction, so as to ensure that the sliding support 41 does not deviate from the predetermined trajectory during the sliding process.
[0040] To ensure a reliable connection between the pin 4142 and the mounting frame 4141, and to facilitate their disengagement, the roller assembly 414 also includes a nut 4146. One end of the pin 4142 has a limiting block 4145, and the other end has an external thread. When the pin 4142 is inserted into a pair of mounting holes, it is limited and engaged with the side wall of the mounting frame 4141 by the limiting block 4145. The threaded end of the pin 4142 passes through the mounting frame 4141 and is threadedly engaged with the nut 4146.
[0041] In order to provide preload to the pin 4142, a spring washer 4147 is provided between the nut 4146 and the mounting frame 4141. The spring washer 4147 is fitted onto the pin 4142 and pressed against the side wall of the mounting frame 4141 by the nut 4146.
[0042] As a further preferred option, the oil pump can be directly connected to the power output side of the electric motor 3, and a bell-shaped cover is provided on the outside of the connection position between the oil pump drive shaft and the electric motor output shaft to protect the connection.
[0043] In addition, the sliding support 41 can also move relative to the support base 1 through an electric moving mechanism, such as a screw mechanism or a gear and rack mechanism.
[0044] The locking assembly 43 includes a locking bolt, one end of which passes through the sliding support 41 and can be threadedly connected to the support base 1, thereby fixing the motor 3 to the support base 1.
[0045] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
