Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a lifting heater for oil tanks. Background Technology

[0002] An loading arm (or arm for loading and unloading liquids) is a type of liquid handling equipment used in industries such as petroleum and chemicals. It features a telescopic, tubular structure and is primarily used to replace traditional hoses for safe and efficient liquid transfer; it is also known as a fluid loading / unloading arm. When transporting high-viscosity crude oil via tanker trucks, loading arms are required for unloading. The front end of the loading arm is often equipped with a heat exchanger to heat the crude oil and reduce its viscosity. To effectively prevent displacement or tipping during dynamic operations, the frame of this equipment must be fixed to the ground at the operating site using anchor bolts. Therefore, the bottom of the frame does not integrate a walking system, and movement requires external transport machinery (such as cranes or hoists). This method increases operational complexity and time costs during equipment movement or installation. Utility Model Content

[0003] This utility model addresses the problems mentioned above by specifically designing a lifting heater for oil tanks, which adds a walking mechanism to improve the mobility of the equipment.

[0004] To achieve the above objectives, this utility model provides a lifting heater for oil tanks, including a submersible pump, an loading arm, and a heat exchanger body. The submersible pump and the loading arm are connected by the heat exchanger body. The heater also includes a frame and a three-way switching valve. The loading arm is movably connected to the frame via a gear and rack lifting mechanism. A three-way switching valve is provided at the connection between the heat exchanger body and the loading arm. One passage of the three-way switching valve is connected to the loading arm, and the other passage is connected to a circulation pipe that leads into the opening of the oil tank. A traveling mechanism is provided at the bottom of the frame, and the traveling mechanism is movably connected to the ground via a hydraulic lifting cylinder.

[0005] Furthermore, the frame includes a base plate, columns, and a support plate arranged parallel to the base plate. The support plate is fixedly connected to the columns, and the walking mechanism is installed at the bottom of the support plate.

[0006] Furthermore, the walking mechanism includes a mounting base and casters. One end of the hydraulic lifting cylinder is fixedly connected to the support plate, and the other end is driven to be connected to the mounting base. The casters are rotatably connected to the mounting base.

[0007] Furthermore, a limiting seat is poured into the ground, and the frame is fixedly connected to the ground through the limiting seat.

[0008] Furthermore, the limiting seat includes a base plate and anchor bolts symmetrically arranged at the four corners of the base plate, and the base plate has through holes adapted to the anchor bolts.

[0009] Furthermore, the limiting seat also includes a stud protective cover that can be detachably connected to the anchor bolt.

[0010] Furthermore, the stud protective cover is fixedly connected with a flange, the cross-section of which covers the through hole.

[0011] Furthermore, reinforcing ribs are fixedly installed between the support plate and the column, and between the base plate and the column.

[0012] Furthermore, the base plate is fixedly connected with a rubber pad.

[0013] In summary, this utility model has the following advantages and beneficial technical effects: 1. This utility model adds a traveling mechanism to the bottom of the frame, which is driven to rise or fall by a hydraulic lifting cylinder. When the equipment moves, the hydraulic lifting cylinder is activated to drive the traveling mechanism to fall, so that the casters contact the ground, and at the same time, the bottom plate of the frame is lifted off the ground to improve the moving efficiency of the equipment.

[0014] 2. The frame of this utility model includes a base plate and a support plate. The base plate is used to cooperate with the limiting seat to fix the frame on the ground. The support plate is used to install and support the walking mechanism, facilitating the movement of the frame and flexibly switching between the fixed and moving modes for convenient use. Reinforcing ribs enhance the stability of the frame structure, and the rubber pad under the base plate increases the tightness of the assembly between the frame and the limiting seat. This not only prevents displacement or deformation during long-term use but also absorbs vibration and impact, maintaining the long-term stability of the connection.

[0015] 3. This utility model involves casting a limiting seat on the ground, and the equipment frame is fixed to the ground by the cooperation of nuts and the limiting seat, which effectively prevents the heat exchange equipment from shifting or overturning during dynamic oil unloading operations.

[0016] 4. The bolt protection cover in this utility model serves two purposes: firstly, it provides oil and dust protection for the threads of the anchor bolts; secondly, it aligns with the anchor bolts by working in conjunction with the through hole in the base plate, and its rigid structure restricts the assembly position of both the frame and the limit seat. The flange is used to limit the position of the stud protection cover, preventing the top of the stud protection cover from protruding through the through hole in the base plate.

[0019] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail as follows: like Figures 1-2 As shown, this embodiment discloses a lifting heater for oil tanks, including a submersible pump 1, an loading arm 2, and a heat exchanger body 3. The heat exchanger body 3 connects the submersible pump 1 and the loading arm 2. It also includes a frame 4 and a three-way switching valve 5. The loading arm 2 is movably connected to the frame 4 via a rack and pinion lift (not shown in the figure), which includes a gear, a rack, a drive motor, and a lifting platform. The rack is laid on the frame 4, and the loading arm 2 is mounted on the lifting platform. When the drive motor outputs power, the drive gear rolls along the rack, and the lifting platform and loading arm 2 rise and fall synchronously with the gear. The rack and pinion lift is existing technology, and its structure and transmission principle will not be described in detail here. A three-way switching valve 5 is provided at the connection between the heat exchanger body 3 and the loading arm 2. One passage of the three-way switching valve 5 is connected to the loading arm 2, and the second passage is connected to the oil inlet of the circulation pipe 6. The oil outlet of the circulation pipe 6 extends into the opening of the oil tank. A traveling mechanism 7 is provided at the bottom of the frame 4, and the traveling mechanism 7 is movably connected to the ground via a hydraulic lifting cylinder 8.

[0020] like Figures 2-3 As shown, the frame 4 includes a base plate 41, a column 42, and a support plate 43 parallel to the base plate 41. The support plate 43 is welded to and fixed to the column 42. The traveling mechanism 7 is installed at the bottom of the support plate 43. The traveling mechanism 7 includes a mounting base 71 and casters 72. The cylinder end of the hydraulic lifting cylinder 8 is fixed to the support plate 43 by fastening screws. The piston part passes through the support plate 43 and drives the mounting base 71. The casters 72 are rotatably connected to the mounting base 71.

[0021] like Figures 4-5As shown, a limiting seat 9 is fixed to the ground by ground casting, and the frame 4 is fixed to the ground by the limiting seat 9. The limiting seat 9 includes a base plate 91 and anchor bolts 92 symmetrically arranged at the four corners of the base plate 91. The base plate 41 has through holes adapted to the anchor bolts 92. The limiting seat 9 also includes a stud protective cover 93 that can be detachably fitted onto the anchor bolts 92. The stud protective cover 93 has an integrally formed flange 94, and the cross-section of the flange 94 covers the through holes. Reinforcing ribs (not shown in the figure) are welded between the support plate 43 and the column 42, and between the base plate 41 and the column 42. A rubber pad (not shown in the figure) is glued to the bottom of the base plate 41.

[0022] The working principle of the lifting heater for oil tanks according to this utility model is as follows: During installation, the equipment is moved by the walking mechanism 7. The hydraulic lifting cylinder 8 is activated, and the piston drives the mounting base 71 and the casters 72 to descend, so that the casters 72 contact the ground until the base plate 41 is lifted off the ground. The height of the base plate 41 from the ground is greater than the height of the anchor bolts 92.

[0023] The equipment is pulled to the vicinity of the pre-set limit seat 9 on the ground by the universal wheel 72. First, remove the stud protective cover 93 on the anchor bolt 92 and pass the stud protective cover 93 through the through hole of the base plate 41. Then, finely adjust the position of the frame 4 until the stud protective cover 93 can be aligned and reinserted into the anchor bolt 92. At this time, the through hole on the base plate 41 is also aligned with the anchor bolt 92.

[0024] Start the hydraulic lifting cylinder 8, the walking mechanism 7 rises, the frame 4 falls until the base plate 41 falls onto the limit seat 9 on the ground, remove the stud protective cover 93 again, screw the matching nut (not shown in the figure) into the anchor bolt 92, and lock the base plate 41 of the frame 4. Finally, insert the stud protective cover 93 back into the anchor bolt 92.

[0025] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
