Description

Technical Field

[0001] This utility model relates to the field of oil container lifting technology, and in particular to an oil container expansion lifting device. Background Technology

[0002] In the operation of the petroleum industry, the modular container serves as an important carrier that integrates equipment, materials and personnel working and living space. Its functional applicability has a key impact on the efficiency and safety of operations. In order to meet the stringent requirements of equipment load-bearing capacity, wind and sand protection, and corrosion resistance, petroleum modular containers are usually made of high-strength steel or alloy materials. They also need to be filled with a large number of precision instruments, heavy equipment and reserve materials, resulting in an overall weight of several tons or even tens of tons.

[0003] Due to the heavy weight of oil container, traditional loading and unloading are carried out using forklifts or cranes. However, when using forklifts, the large size of the container and the difficulty in controlling its center of gravity can easily lead to tipping over. Furthermore, forklift operations require a very flat site, and in muddy, soft, or rugged terrain commonly found in oilfield operations, forklifts struggle to maintain stability and operate precisely. While cranes can lift the container, the lifting process requires repeated adjustments to the position and angle of the slings, which is time-consuming. Additionally, uneven stress at the contact points between the slings and the container can easily damage the container's surface. Therefore, we have developed an extended lifting device for oil container. Summary of the Invention

[0013] Beneficial effects: By combining the extension mechanism and the lifting mechanism, the extension mechanism can move the lifting mechanism outward, and then the lifting mechanism can lift the oil container body upward. The transport vehicle can drive directly under the container body. Subsequently, the lifting mechanism slowly descends, accurately placing the container body on the vehicle chassis, thereby transferring the oil container body to the vehicle.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] As attached Figure 1 To be continued Figure 6 As shown: An oilfield container expansion and lifting device includes a container body 1, with an expansion and lifting assembly installed on the outside of the container body 1. The expansion and lifting assembly consists of two sets of expansion mechanisms 2 and two sets of lifting mechanisms 3. The two sets of expansion mechanisms 2 are located on the upper and lower sides of the left and right ends of the container body 1, respectively. Each expansion mechanism 2 includes an expansion outer tube 201 and a first motor 203. An expansion inner tube 202 is slidably connected to the inner wall of each expansion outer tube 201. A first reducer 204 is installed between each set of expansion outer tubes 201, and the first motor 203 is connected to the first reducer 204 through a transmission connection. Each first reducer 204... Each of the four components has an output end along the direction of the outer tube 201, and a first lead screw 205 is installed at the output end. The other end of each first lead screw 205 is rotatably connected to a mounting plate 206. A nylon wheel 207 is installed on each mounting plate 206, and the nylon wheel 207 rolls in contact with the inner tube 202. The first lead screw nut 213 is connected to the inner tube 202. When the first motor 203 works, it drives the first reducer 204 to rotate. At the same time, the first lead screw 205 rotates on the first lead screw nut 213, which in turn drives the inner tube 202 to move, thereby pushing the lifting mechanism 3 to move outward.

[0024] As attached Figure 2 Appendix Figure 4 With appendix Figure 5 As shown: Each extended outer tube 201 has a connecting seat 208 installed on its outer surface. Each connecting seat 208 has a fixing seat 209 installed on one side by bolts. The fixing seat 209 is connected to the outer surface of the container body 1. By using the cooperation of the fixing seat 209 and the connecting seat 208, the container body 1 and the extended outer tube 201 can be connected, thereby ensuring the stable lifting of the container body 1 in the future. Each extended outer tube 201 and extended inner tube 202 is equipped with a dustproof protective cover 211. The dustproof protective cover 211 can prevent sand and gravel from entering the gap between the extended outer tube 201 and the extended inner tube 202, which may cause wear and jamming of the guide rail, as well as problems such as jamming or abnormal wear of the transmission components due to dust accumulation.

[0025] As attached Figure 1 Appendix Figure 2 With appendix Figure 3 As shown: Each lifting mechanism 3 is installed at the front and rear ends of each extension mechanism 2. Each lifting mechanism 3 includes an inner lifting tube 301, and an outer lifting tube 302 is slidably connected to the outside of each inner lifting tube 301. A motor reducer 303 is installed on the outside of each outer lifting tube 302, and a second lead screw 304 is rotatably connected inside each outer lifting tube 302. The motor reducer 303 and the second lead screw 304 are connected by a gearbox. Both the first lead screw 205 and the second lead screw 304 use trapezoidal threads, allowing for pause and self-locking at any position during operation. The material used is 40RC, which is highly wear-resistant and has high hardness. With high tensile strength and yield strength, each second screw 304 is externally equipped with a second screw nut 305, which is connected to the lifting inner tube 301. When the motor reducer 303 works, it drives the second screw 304 to rotate, and at the same time, the second screw nut 305 drives the lifting inner tube 301 to rise, thus completing the upward lifting of the container body 1. Then, the vehicle chassis is moved above the container body, and the container body 1 is slowly lowered to transfer the oil container body 1 to the vehicle. It can conveniently lift and transfer the oil container body 1, and the operation is convenient and fast. It has strong stability and high safety, and is suitable for widespread use.

[0026] As attached Figure 4 As shown: Each lifting outer tube 302 and the expansion inner tube 202 is provided with an anti-shear block 306. The anti-shear block 306 can be used to construct a rigid anti-shear support system between the lifting outer tube 302 and the expansion inner tube 202, effectively avoiding the problem of deformation of the lifting outer tube 302 and the expansion inner tube 202 due to shear force.

[0027] As attached Figure 1 Appendix Figure 2 With appendix Figure 6As shown: Each lifting mechanism 3 has a support mechanism 4 at its bottom and on its exterior. Each support mechanism 4 includes a support base 401. A spherical assembly column 402 is fixedly connected to the upper surface of each support base 401. A hanging plate 403 is provided on the exterior of each spherical assembly column 402. The upper surface of each hanging plate 403 is connected to the bottom of the lifting inner tube 301. A set of hooks 404 is hung on the exterior of each hanging plate 403, and the bottom end of the hooks 404 is connected to the upper surface of the support base 401. The bottom of the lifting inner tube 301 is provided with an insertion hole that matches the spherical assembly column 402, allowing the spherical assembly column 402 to be inserted into the lifting inner tube 301. A connection is formed by hanging the hook 404 on the hanging plate 403, which further enhances the firmness of the connection between the support base 401 and the lifting inner tube 301, so that the support base 401 can stably support the lifting inner tube 301. Each support base 401 is equipped with a plug rod 405, and each plug rod 405 is provided with a cotter pin 406. Each lifting outer tube 302 is provided with a fixing plate 5 for stabilizing the support base 401. By inserting the plug rod 405 into the fixing plate 5 and the support base 401, and then inserting the cotter pin 406 into the plug rod 405, the support base 401 can be stabilized on the lifting outer tube 302.

[0028] As attached Figure 1 As shown: Each set of connecting seats 208 has a reinforcing rod 6 on one of the connecting seats 208.

The reinforcing rod 6 can be used to connect the bottom connecting seat 208 and the bottom of the lifting inner tube 301, further enhancing their stability when lifting the container body 1.

[0029] Working principle: When the container body 1 needs to be transferred and transported, the first motor 203 is controlled to work, which drives the first reducer 204 to rotate. At the same time, the first lead screw 205 rotates on the first lead screw nut 213, which in turn drives the extension inner tube 202 to move, thereby pushing the lifting mechanism 3 to move outward. Then, the motor reducer 303 is controlled to work, which drives the second lead screw 304 to rotate. At the same time, the second lead screw nut 305 drives the lifting inner tube 301 to rise, thus completing the upward lifting of the container body 1. Then, the vehicle chassis is moved above the container body, and the container body 1 is controlled to slowly descend, thereby transferring the oil container body 1 onto the vehicle. This method allows for convenient lifting and transfer of the oil container body 1, is easy and fast to operate, has strong stability, and high safety, making it suitable for widespread use.
