Abstract
Description
Technical Field
[0001] This invention belongs to the field of elevator maintenance technology, specifically relating to a fully enclosed flow-guiding elevator oil collection box. Background Technology
[0002] The oil collection box at the elevator pit is an important component in elevator maintenance. Its main function is to collect waste oil and oil stains that drip during the lubrication of the elevator guide rails, preventing oil from directly seeping into the pit and causing environmental pollution or corrosion of the pit equipment. The collected waste oil can be settled and recycled, reducing resource waste and environmental pollution.
[0003] However, existing elevator oil collection boxes have the following defects: 1. Traditional oil collection boxes use a semi-enclosed embedded design, which cannot completely seal with the elevator guide rail, causing a small amount of lubricating oil to leak out from the gaps, which will contaminate the pit floor. 2. The oil collection box is installed at the bottom of the guide rail. When collecting waste oil, maintenance personnel need to manually remove and pour it out. After pouring, they also need to wipe it with a cloth, which is not only time-consuming and labor-intensive, but also makes it easy for waste oil to get on the maintenance personnel. 3. The capacity of the elevator oil collection box is about 100ml-200ml. The oil collection box is a consumable item for elevators. After repeated disassembly and reassembly, it is prone to deformation and oil leakage, requiring frequent replacement. At the same time, its small capacity means that waste oil needs to be cleaned frequently when the elevator is used frequently, which further increases maintenance costs and workload.
[0004] In summary, existing elevator oil collection boxes suffer from drawbacks such as poor sealing performance, cumbersome maintenance, short service life, and limited capacity. Therefore, there is an urgent need to develop a flow-guiding type elevator oil collection box to meet the practical needs of leak-proof, convenient, and durable elevator maintenance. Summary of the Invention
[0005] The purpose of this invention is to provide a fully enclosed flow-guiding elevator oil receiving box to solve the problems of poor sealing performance, cumbersome maintenance and operation, short service life and limited capacity of existing elevator oil receiving boxes.
[0006] This invention is achieved through the following technical solution: A flow-guiding elevator oil receiving box includes an oil receiving box body, a sealing component, a flow-guiding component, and a fixing component; The main body of the oil receiving box is triangular in shape, consisting of a left oil box 1 and a right oil box 2 connected together. Each of the three apex corners of the triangular structure is provided with a fixed end and a bolt hole. The two fixed ends at the connection between the left oil box 1 and the right oil box 2 are fastened together by a set of fixing components, and a 3-5mm wide sealing strip is provided at the connection. Each of the other two fixed ends of the triangular structure is also equipped with a set of fixing components. The left oil box 1 and the right oil box 2 are connected at the middle of a T-shaped mounting hole for installing elevator guide rails. When the oil box body is installed with the elevator guide rail, a sealing component is used for sealing. After installation, an oil-containing cavity box structure with a volume of 100ml-150ml can be formed. The sealing component is a nitrile rubber gasket 6, which is glued to the T-shaped mounting hole on the inside of the oil receiving box body. A nitrile rubber gasket 6 is also glued to the guide rail. The flow guiding component includes an oil leakage hole 5 located at the bottom of the right oil box 2. The hole has an internal thread and can be connected to a pagoda connector. One end of the oil-resistant rubber hose is interference-fitted with the pagoda connector, and the other end is inserted into a waste oil collection container. One set of fixing components includes bolts and fixing bolts and nuts 4. The assembled oil receiving box body is fixed to the guide rail by the three sets of fixing components.
[0007] Furthermore, the main body of the oil receiving box is made of nylon 66 material and is CNC machined or injection molded.
[0008] Furthermore, the left oil box 1 and the right oil box 2 are two right-angled triangle structures, symmetrically arranged, with the length of their long side being 15-20cm and the length of their short side being 10-12cm. The two short sides are connected to form the back plate 3 of the oil box.
[0009] Furthermore, the left oil box 1 and the right oil box 2 are each provided with a fixed end at the two acute angles, and bolt holes are opened on them; the two fixed ends of the left oil box 1 and the right oil box 2 at the long side are fastened together by a set of fixing components; a set of fixing components is also installed on the fixed ends at the two short sides.
[0010] Furthermore, the nitrile rubber sealing gasket 6 has a cross-sectional dimension of 10mm×5mm and a Shore hardness of 30-40 degrees.
[0011] Furthermore, the diameter of the oil leakage hole 5 is Φ20mm.
[0012] Furthermore, the pagoda connector is of specification G1 / 2, which is screwed into the oil leakage hole 5 through the thread and coated with thread sealant.
[0013] Furthermore, the inner diameter of the oil-resistant rubber hose is Φ10mm.
[0014] Furthermore, the connection between the oil-resistant rubber hose and the pagoda connector is secured with a hose clamp with a diameter of Φ8-15mm.
[0015] Furthermore, the bolts are M8 size 304 stainless steel hex bolts with a length of 45-50mm.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Fully sealed and leak-proof: This invention completely solves the problem of oil leakage from gaps in traditional oil receiving boxes by tightly fitting the nitrile rubber sealing gasket with the guide rail and tightening the bolts at the fixed end of the oil receiving box body, effectively avoiding pollution of the pit floor; 2. No disassembly or maintenance required: The flow-guiding design allows waste oil to flow directly into the collection container through the hose, eliminating the need to disassemble the oil collection box to clean up the waste oil. Once installed, it can be maintained for life, greatly reducing the workload and operation difficulty for maintenance personnel. 3. Large capacity and low frequency: It can receive and collect external containers, such as mineral water bottles, which have a much larger capacity than traditional oil collection boxes. Combined with the flow-guiding oil discharge structure, it significantly reduces the frequency of waste oil collection and further improves maintenance efficiency. 4. High durability: The main body of the oil receiving box is made of nylon, which has high mechanical strength, wear resistance, and aging resistance. It does not require frequent disassembly and assembly, avoiding deformation damage, extending service life, and reducing equipment replacement costs. Attached Figure Description

Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] like Figures 1-3 As shown, the present invention provides a flow-guiding elevator oil receiving box, which includes an oil receiving box body, a sealing component, a flow-guiding component, and a fixing component.
[0023] The main body of the oil receiving box is made of Nylon 66 material, CNC machined or injection molded, and has a triangular structure. It consists of a left oil box 1 and a right oil box 2 connected together. The left and right oil boxes are two right-angled triangles, symmetrically arranged, with the long side length being 15-20cm and the short side length being 10-12cm. The two short sides are connected to form the oil box back plate 3. Both the left oil box 1 and the right oil box 2 have fixing ends at the two acute angles, with bolt holes. The two fixing ends of the left oil box 1 and the right oil box 2 at the long sides are fastened together by a set of fixing components, and a 3-5mm wide sealing strip is provided at the connection point. Each of the two fixing ends at the short sides is also equipped with a set of fixing components.
[0024] A T-shaped mounting hole for installing elevator guide rail is provided in the middle of the connection between the left oil box 1 and the right oil box 2. When the oil box body is installed with the elevator guide rail, a sealing component is used for sealing. Thus, after installation, an oil-containing cavity box structure with a volume of 100ml-150ml can be formed.
[0025] The sealing component is a nitrile rubber gasket 6 with a cross-sectional dimension of 10mm × 5mm and a Shore hardness of 30-40 degrees. It is glued to the T-shaped mounting hole on the inside of the oil receiving box body, and a nitrile rubber gasket 6 is also glued to the guide rail. The connection between the oil receiving box body and the elevator guide rail achieves a full-seal surface contact at the connection point through this sealing component.
[0026] The flow guiding assembly includes an oil drain hole 5 with a diameter of Φ20mm located at the bottom of the right oil box 2. The oil drain hole has internal threads and can be connected to a pagoda connector of G1 / 2 specification. The pagoda connector is screwed into the oil drain hole 5 and thread sealant is applied. One end of an oil-resistant rubber hose with an inner diameter of Φ10mm is interference-fitted to the pagoda connector and locked with a hose clamp with a diameter of Φ8-15mm; the other end is inserted into the inlet of a waste oil collection container, such as a 500mL mineral water bottle.
[0027] One set of fixing components includes M8 304 stainless steel hex bolts and fixing bolt nuts 4, with a bolt length of 50mm. This invention uses three sets of fixing components to tightly secure the assembled oil receiving box body to the guide rail.
[0028] The installation process of the flow-guiding elevator oil receiving box of the present invention is as follows: 1. Installation of sealing components: Adhere the nitrile rubber sealing gasket 6 to the inside of the oil receiving box body, ensuring that the rubber sealing gasket 6 is tightly fitted to the inner surface of the oil receiving box body without gaps; 2. Assembly of the main body of the oil receiving box Wipe the left oil box 1, right oil box 2 and oil box back plate 3 made of nylon 66 clean. Then, use M8 bolts with a length of 50mm to pass through the preset bolt holes one by one and tighten them with the fixing bolt nuts 4. The tightening torque is 2.5-3N·m. After assembly, check whether there are gaps at the connection of the oil box body to ensure that the oil cavity is well sealed.
[0029] 3. Fixing the main body of the oil collection box Use connectors to fix the assembled oil collection box body onto the nitrile rubber sealing gasket 6 that has been wrapped around the guide rail, ensuring that the oil collection box body and the guide rail are completely sealed through the sealing components. 4. Installation of the flow guiding component Apply thread sealant to the internal thread of the oil drain hole 5 at the bottom of the oil collection box body. Screw the G1 / 2 specification pagoda connector clockwise into the oil drain hole 5 to the bottom. Then, put one end of the Φ10mm inner diameter oil-resistant rubber hose onto the pagoda connector and tighten it with a hose clamp with a diameter of Φ8-15mm. Adjust the hose length to 30-50cm according to the pit space. Insert the other end into the inlet hole of the waste oil collection container and fix the hose to the pit support with a pipe clamp to prevent the hose from bending and clogging.
[0030] Waste oil dripping from the elevator guide rail enters the oil-receiving chamber of the oil collection box and then flows naturally into the waste oil collection container through the waste oil leakage hole 5, the pagoda connector, and the hose. When the oil drum is full, it can be replaced with an empty drum without disassembling the oil collection box, further demonstrating the maintenance-free advantage.
[0031] In this embodiment, the main body of the oil collection box is made of nylon, which has good mechanical properties and oil resistance; the nitrile foam rubber strip has excellent sealing and elasticity, and can adapt to the slight undulations on the guide rail surface; the hose is made of oil-resistant rubber tubing to ensure that it is not prone to aging and cracking during long-term use. This implementation method is simple to operate and easy to install, and can be widely used in various elevator pit waste oil collection scenarios.
