Description

Technical Field

[0001] This utility model relates to a suspended motor assembly / disassembly and waste oil collection device. Background Technology

[0002] In industrial production, suspended motors (typically referring to motors installed upside down with their output shaft facing upwards and connected to a speed reducer) are widely used in various drive equipment. When performing maintenance or repairs on these motors, they must first be removed from the speed reducer to which they are connected.

[0003] The following technical challenges exist during the disassembly and assembly process:

[0004] 1. Waste oil leakage pollution problem. Before disconnecting the motor from the reducer, although most of the gear oil can be drained through the reducer's drain hole, due to structural limitations, a considerable amount of waste oil usually remains at the bottom of the reducer and in the meshing chamber (practice has shown that the residual amount can often reach about 6 liters). When the motor and reducer are separated, this residual waste oil will leak directly from the joint surface due to gravity, spilling onto the equipment, ground, or work environment below, causing serious oil pollution. This not only increases the difficulty and workload of on-site cleaning but also violates increasingly stringent environmental protection requirements. The oil pollution may also pose safety hazards such as slipping.

[0005] 2. Difficulty and Safety Hazards in Disassembly and Assembly. Suspended motors are typically installed at a high position, with their bottom suspended above the ground or a stable work platform. During disassembly, maintenance personnel need to loosen the bolts securing the motor and reducer at a height. After the bolts are loosened, the motor is in a "semi-free" state, and its weight (usually quite heavy) requires manual lifting or support. Because the workspace is often narrow and located at a height, maintenance personnel must laboriously move the heavy motor in unnatural postures (such as tiptoeing, tilting their heads back, or leaning forward) to detach it from the reducer output shaft and move it away. This process is not only extremely physically demanding but also carries a significant risk of falls, potentially causing equipment damage and personal injury. Similarly, during installation, maintenance personnel need to manually lift the heavy motor at a height, precisely aligning it with the reducer output shaft and the bolt holes. This operation is difficult, time-consuming, and also carries the risk of falling objects and muscle strain. Existing simple support tools are ill-suited to the disassembly and assembly needs of heavy components in suspended, confined spaces.

[0006] Therefore, existing technologies for disassembling and assembling suspended motors generally suffer from two major problems: environmental pollution from waste oil leakage and difficulties in manual operation, posing high safety risks. There is an urgent need to develop a dedicated device to solve these problems. Utility Model Content

[0007] To solve at least one of the above-mentioned technical problems, this utility model provides a suspended motor disassembly and assembly and waste oil collection device, comprising:

[0008] Waste oil collection module includes a waste oil tank, the top of which has a first opening, the lower part of which has a second opening and a drain plug that is detachably connected to the second opening;

[0009] The lifting module is fixedly installed at the bottom of the center area of ​​the top of the waste oil tank, and the lifting end is fixedly connected to the center area of ​​the bottom of the tray;

[0010] The disassembly and assembly platform module includes a tray and an annular oil collection sidewall extending vertically upward along the edge of the tray. An oil drain valve is also provided at the bottom of the tray.

[0011] The oil guiding module includes an oil pipe, one end of which is connected to the outlet of the oil drain valve, and the other end is connected to the first opening of the waste oil tank.

[0012] The guide module includes vertically arranged guide rods and sleeve assemblies fitted onto each guide rod. The sleeve assembly includes a fixed sleeve and a movable sleeve. The fixed sleeve is fixedly connected to the side wall of the waste oil tank and its bottom is flush with the bottom of the waste oil tank. The movable sleeve is fixedly connected to the annular oil collecting side wall.

[0013] In some implementations, the upper end of the guide rod extends to a first height, which is greater than or equal to the maximum stroke end height of the disassembly and assembly platform module; wherein, the maximum stroke end height is the height of the disassembly and assembly platform module when it is lifted to its highest position by the lifting module.

[0014] In some implementations, a locking module is also included, comprising a locking set screw and a threaded hole disposed on the side wall of the movable sleeve, the locking set screw passing through the threaded hole to abut against the guide rod; the sleeve assembly and the guide rod are clearance-fitted.

[0015] In some implementation schemes, the drain valve is a manual ball valve or an electric ball valve, and the lifting module is a hydraulic jack, an electric jack, or an electro-hydraulic jack.

[0016] In some implementations, the tubing is a flexible hose.

[0017] In some implementations, the disassembly platform module also includes a boss, which is set on the tray and has anti-slip texture on its upper surface. The height of the annular oil collecting sidewall is at least 150 mm.

[0018] In some implementations, the height of the fixed sleeve is equal to the sum of the height of the waste oil tank and the height of the lifting module body, and the height of the movable sleeve is equal to the height of the annular oil collecting sidewall.

[0019] In some implementations, the number of guide rods, fixed sleeves, and movable sleeves is n, where n≥2; the inner diameters of the fixed sleeves and movable sleeves are the same.

[0020] In some implementation schemes, the volume of the waste oil tank is ≥10L.

[0021] In some implementations, the tray surface is also provided with anti-slip texture, and the bottom of the waste oil tank is also provided with at least two fixing rings.

[0022] All materials used in this utility model are existing materials and do not involve new materials; all processes and methods used are existing technologies and do not involve new processes and methods.

[0023] Compared with existing technologies, the beneficial effects of this utility model are as follows: First, by constructing a four-level waste oil splash prevention structure consisting of an annular oil collecting sidewall, a tray drain valve, an oil pipe, and a waste oil tank, specifically, the oil splashed at the moment of motor separation is completely intercepted by the ≥150mm high oil collecting sidewall; the oil is actively guided by the drain valve at the bottom of the tray to avoid manual scooping; the oil pipe is directly connected to the first opening of the waste oil tank to prevent intermediate leakage; the drain plugs on the sidewall of the waste oil tank are centrally cleaned, preventing oil from falling to the ground at the source and reducing the pollution area. Second, safe lifting is achieved through the installation of the lifting module. Specifically, the bottom of the lifting module is fixed to the center of the top of the waste oil tank, and the lifting end is connected to the center of the bottom of the tray, so that the force flow transmission is not biased; the bottom of the fixing sleeve is flush with the waste oil tank to ensure that the verticality error of the guide rod is small; the guide rod is higher than the maximum stroke to prevent the tray from falling out of the guide system, thereby ensuring zero tipping during the motor lifting process and eliminating the risk of falling from a height. Secondly, the modular design reduces design redundancy. Specifically, the waste oil tank also serves as the lifting base; the fixed sleeve of the guide module is welded to the side wall of the waste oil tank, so no additional support frame is needed; the movable sleeve is fixed integrally with the oil collection side wall, reducing independent parts, thus simplifying the device and making it suitable for high-altitude and narrow working surfaces, so that basic safety requirements are still met even in the simplest implementation.

[0024] Furthermore, in some embodiments of this utility model, the guide rod length being greater than or equal to the lifting stroke can prevent derailment; a triple leak-proof guarantee is formed by a ≥150mm high annular oil collection sidewall + a flexible hose oil guiding channel + a ≥10L waste oil tank, with the waste oil tank effectively absorbing 6L of residual gear oil splashed during motor separation; the flexible hose connection adapts to lifting and deflection, avoiding secondary leakage caused by pipeline rupture; the boss further positions the suspended motor and improves the waste oil guiding efficiency, and its anti-slip texture on the upper surface can also prevent the risk of motor displacement; the electric ball valve option supports remote opening and closing of the drain valve, eliminating the need for operators to come into contact with oil; the locking module (locking top screw + clearance fit sleeve) forms a mechanical hard lock on the guide rod to prevent the tray from falling accidentally; the anti-slip texture of the tray increases the friction coefficient of the motor base, eliminating the risk of motor slippage during disassembly and assembly; the same diameter sleeve + double sleeve guide structure ensures that the tray lifting and lowering is smooth and reduces the time required for aligning the motor bolt holes; the electric jack enables one-button lifting and lowering, allowing a single person to complete the disassembly and assembly work that originally required three people.

[0032] Terms such as “comprising” and “including” indicate that, in addition to the components that are directly and explicitly stated in the specification and claims, the technical solution of this utility model does not exclude the presence of other components that are not directly or explicitly stated.

[0033] This utility model provides a suspended motor assembly / disassembly and waste oil collection device, and offers the following technical solution, which will be described in detail below with reference to the accompanying drawings:

[0034] Example 1

[0035] This embodiment describes a suspended motor assembly / disassembly and waste oil collection device. Figure 1 The structure of the suspended motor disassembly and assembly and waste oil collection device disclosed in this embodiment is shown. The suspended motor disassembly and assembly and waste oil collection device includes a waste oil collection module 1, a lifting module 2, a disassembly and assembly platform module 3, an oil guiding module 4, a guiding module 5, and a locking module 6.

[0036] The waste oil collection module 1 includes a waste oil tank 11, and the top of the waste oil tank 11 is provided with a first opening 111. Figure 1 The middle part is obscured; please refer to [link / reference]. Figure 2The first opening 111 connects to the lower port of the oil guiding module 4, thereby guiding the waste oil collected by the disassembly platform module 3 into the waste oil tank 11. The lower side wall of the waste oil tank 11 has a second opening 112 and a drain plug 113 detachably connected to the second opening 112. The drain plug 113 and the second opening 112 cooperate to seal the waste oil tank 11 during disassembly and assembly. After disassembly and assembly, the waste oil is discharged all at once by unscrewing the drain plug 113. Therefore, the function of the waste oil collection module 1 is to collect and temporarily store the residual waste oil in the motor during disassembly or maintenance of the suspended motor to prevent... Waste oil spills and pollutes the working environment. The bottom of the waste oil tank 11 is equipped with three fixing rings 114. When performing high-altitude operations, this device often needs to be placed on an aerial platform frame. The risk of tipping can be reduced by securing the device to the aerial platform frame with ropes threaded through the fixing rings 114. The lifting module 2 is a hydraulic jack, fixedly installed in the central area of ​​the waste oil tank 11. Its lifting end is connected to the disassembly and assembly platform module 3. The lifting module 2 moves up and down, causing the disassembly and assembly platform module 3 connected to its lifting end to move up and down. The disassembly and assembly platform module 3 includes a tray 31 and an annular oil collection side extending vertically upwards along the edge of the tray 31. The bottom of the wall 32 and tray 31 is also equipped with an oil drain valve 33. The tray 31 serves to support the suspended motor. The annular oil collection side wall 32 prevents waste oil from splashing or overflowing. The bottom oil drain valve 33 is a manual ball valve. Waste oil from the suspended machine flows to the tray 31 and enters the waste oil tank for temporary collection and storage through the interconnected oil drain valve 33, oil guide module 4, and first opening 111. The oil guide module 4 is a flexible hose, whose bending characteristics can adapt to the lifting and disassembling of the platform module, avoiding pipeline rupture and waste oil leakage. The guide module 5 ensures that the lifting and lowering does not deviate during the lifting and lowering process. It includes 4 guides. The system includes a rod 51 and four sets of sleeve assemblies 52. Each sleeve assembly 52 includes a fixed sleeve 521 and a movable sleeve 522. The fixed sleeve 521 is fixedly connected to the side wall of the waste oil tank 11, and its bottom is flush with the bottom of the waste oil tank 11, requiring no additional support frame. The movable sleeve 522 is fixedly connected to the annular oil collecting side wall 32, ensuring that the movement trajectory of the disassembly / assembly platform module 3 perfectly matches the vertical guide rod 51. Simultaneously, the locking module 6 further secures the disassembly / assembly platform module 3 to its corresponding position to prevent the suspension motor from falling and overturning in case of a malfunction in the lifting module 2. The locking module 6 includes a locking screw 61 and a threaded hole 62 (in...). Figure 1 and Figure 2Since the image shows the locking screw 61 inserted into the threaded hole 62, the threaded hole 62 is blocked by the locking screw 61 when it is labeled. Therefore, the protruding part is labeled as the locking screw 61, and the edge of the protruding part is labeled as the threaded hole 62. It should be understood that the edge here is actually the threaded hole 62 blocked by the locking screw 61. The threaded hole 62 is set on the movable sleeve 522. The locking screw 61 and the threaded hole 62 cooperate with each other. The locking screw 61 rotates and inserts into the threaded hole 62, pressing against the guide rod 51. A locking state is formed by friction, thereby providing a stable support for the disassembly and assembly platform module 3 and enhancing safety performance.

[0037] Example 2

[0038] In this embodiment, the tray surface is also provided with anti-slip texture, and the rest is the same as in embodiment 1.

[0039] Example 3

[0040] In this embodiment, the drain valve is an electric ball valve, the lifting module is an electro-hydraulic jack, and the rest is the same as in embodiment 1.

[0041] Example 4

[0042] In this embodiment, a boss 34 is also provided on the tray 31. The boss 34 is provided with anti-slip texture. The function of the boss 34 is to allow the suspended motor to be placed directly on the boss 34 during disassembly. Due to the height difference, the waste oil in the suspended motor flows into the tray 31 and then flows into the waste oil tank through the drain valve. The rest is the same as in embodiment 1.

[0043] Example 5

[0044] In this embodiment, no fixing ring is provided at the bottom of the waste oil tank; otherwise, it is the same as in Embodiment 1.
