Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil depot equipment technology, specifically a sweeping trough handle used in conjunction with oil tank cars on railway trestle bridges in oil depots. Background Technology
[0002] The railway trestle of the oil depot is equipped with loading arms. There are generally four types of railway oil tank cars: G60K, G17DK, G70K, and GQ70. Except for the GQ70 type oil tank car, most of the residual oil in the oil tank car will automatically collect in the groove below the tank opening. However, most of the residual oil in the other G60K, G17DK, and G70K type oil tank cars cannot automatically collect in the groove below the tank opening. When unloading oil at railway trestle bridges, operators use an loading arm to insert it from the top of the tanker car's opening to the bottom. After unloading and stopping the pump, in G60K, G17DK, and G70K models, most of the residual oil cannot automatically collect in the groove below the tanker opening. Furthermore, due to the loss of power in the loading arm, the oil in the loading arm will flow back into the tanker car due to gravity, leaving some residual oil at the bottom of both ends. The loading arm pump alone cannot completely remove all the oil from the tanker car; the residual oil in G60K, G17DK, and G70K models is more than in GQ70 models. If this residual oil is not recovered, it not only wastes resources and affects economic efficiency but also poses potential safety hazards. Existing residual oil recovery devices have several problems, such as small suction area, heavy weight making manual operation difficult, and a tendency to break or slip during operation, failing to completely remove residual oil. Utility Model Content
[0003] The purpose of this invention is to provide a sweeping handle for use with oil tank cars on railway trestle bridges in oil depots, so as to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows:
[0005] A trough sweeper for use with oil tank cars on a railway trestle in an oil depot, comprising: a handle and a head; the handle is made of an aluminum tube, with a reinforcing aluminum tube added from the middle to the end of the aluminum tube; the head is composed of an aluminum plate, two semi-circular aluminum sheets, and oil-resistant and anti-static thick adhesive; the aluminum tube has a gap on one side of the connection point with the handle for inserting the aluminum plate; the radii of the two semi-circular aluminum sheets are larger than the aluminum tube and cover the connection point between the aluminum tube and the handle; the semi-circular aluminum sheets have screw holes and are fixed to the aluminum plate and the handle by aluminum bolts; the oil-resistant and anti-static thick adhesive is welded to the aluminum plate by three aluminum rivets.
[0006] Furthermore, the handle of the sweeping trough is 3.98m long, the inner diameter of the aluminum tube is 3.0cm, the outer diameter is 3.5cm, the thickness is 0.25cm, and the length of the reinforcing aluminum tube is not less than 50cm.
[0007] Furthermore, the head of the sweeping handle is an aluminum plate with a thickness of 0.3cm, a length of 40cm, and a width of 14.5cm. The aluminum plate is cut in the middle with a gap of 8.5cm in length and 3.5cm in width, and the aluminum tube is inserted into the middle of the cut in the aluminum plate.
[0008] Furthermore, the aluminum tube and the two semi-circular aluminum sheets are clamped together by three copper screws and bolts.
[0009] Furthermore, the oil-resistant and antistatic thick adhesive is a gas-insulated sheet measuring 40cm in length and 14cm in width.
[0010] Furthermore, an oil-resistant, anti-slip, anti-static, and anti-slip soft rubber pad is provided at the handle of the aluminum tube.
[0011] Compared with existing technologies, the sweeping trough handle used in conjunction with the oil tanker on the railway trestle of this utility model effectively solves the problems existing in the prior art through its ingenious structural design. It has the advantages of being compact and flexible, highly practical, having high oil sweeping efficiency, low labor intensity, safety and reliability, and being easy to maintain. On the one hand, it can effectively recover residual oil in the oil tanker, ensuring that residual oil is not wasted and guaranteeing economic benefits, while improving the safety and convenience of the operation. On the other hand, it allows for inspection and maintenance outside the depot, reducing the frequency and risk of welding operations in the depot area, effectively improving the safety of equipment maintenance operations. Replaced parts can be reused as emergency spare materials, further reducing maintenance costs. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the sweeping groove handle of this utility model.
[0013] Among them, 1 is the handle, 2 is the reinforced aluminum tube, 3 is the oil-resistant and anti-static thick rubber, 4 is the copper screw, 5 is the aluminum plate, 6 is the aluminum rivet, and 7 is the semi-circular aluminum sheet. Detailed Implementation
[0014] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0015] like Figure 1The sweeping handle shown has a handle 1 that is 3.98m long, with an inner diameter of 3.0cm, an outer diameter of 3.5cm, and a thickness of 0.25cm made of aluminum tubing. The handle is made of aluminum tubing, with a reinforcing aluminum tube 2 at least 50cm long added from the middle to the end, effectively increasing the hardness of the aluminum tubing. During the sweeping process, operators often need to lift or pull the handle with force. The addition of the reinforcing aluminum tube prevents the handle from breaking due to excessive force, improving the reliability and durability of the device.
[0016] Optionally, an oil-resistant, anti-slip, anti-static, and non-slip soft rubber pad (not shown in the diagram) is provided at the aluminum tube handle. This pad is typically installed on reinforced aluminum tubes, increasing friction while preventing static electricity. It provides a more secure grip on the handle, reducing the risk of slippage and ensuring safer operation. When operators are sweeping the tanker from the front and rear of the tanker towards the central trough, even with oily hands, they can maintain a firm grip on the handle, ensuring accurate operation.
[0017] The sweeping handle head is composed of a 0.3cm thick aluminum plate 5. An aluminum tube is cut into the middle of the aluminum plate 5 to the required diameter, and then inserted into the cut. The two semi-circular aluminum sheets 7 have radii larger than the aluminum tube and wrap around the connection point between the aluminum tube and the handle. The semi-circular aluminum sheets 7 have screw holes and are secured to the handle with aluminum bolts, clamping between the aluminum tube 5 and the half-tube to tighten the handle head. Oil-resistant and anti-static thick adhesive 3 is welded to the aluminum plate 5 using three aluminum rivets. The aluminum plate is 40cm long and 14.5cm wide. The entire sweeping handle is composed of an aluminum plate and oil-resistant and anti-static thick adhesive, secured with aluminum bolts. This structure is durable, and the handle head can be easily replaced when the oil-resistant and anti-static thick adhesive wears or ages, reducing maintenance costs. For example, during long-term use, the oil-resistant and anti-static thick rubber may experience wear and aging. Thanks to the design of the handle head secured by the copper screw 5, the old handle head can be easily removed simply by loosening the screw 5, and the new handle head can be installed by tightening the screw 5, without needing to replace the entire sweeping handle. The old handle head can be taken outside the oil depot area to remove the aluminum rivets, and the worn and aged oil-resistant and anti-static thick rubber can be replaced. This effectively prevents maintenance work inside the oil depot, reducing the frequency and safety risks of aluminum rivet welding. Furthermore, after replacing the old handle head with the oil-resistant and anti-static thick rubber, it can be re-welded securely with aluminum rivets, becoming a new emergency spare material. This achieves the recycling of handle heads, reduces wear and tear, and lowers the purchase cost of such emergency spare materials.
[0018] The sweeping handle is mainly made of aluminum, which makes it lightweight, explosion-proof, oil-resistant, and durable. By increasing the sweeping area of the handle head and lengthening the aluminum tube, the reliability, flexibility, and accuracy of operation are ensured. When the operator sweeps the oil tanker from the bottom of both ends of the tanker towards the middle trough, it can effectively sweep all the residual oil at the bottom of both ends of the tanker towards the middle trough for collection and recycling. This solves the problem of residual oil that cannot be sucked up by the loading arm pump head and the problem of residual oil in the tanker not being able to automatically collect in the trough below the tanker opening, thus improving the efficiency and economic benefits of residual oil recovery.
