Description

Technical Field

[0001] This utility model relates to a tank transport vehicle, and more particularly to a turntable mounting structure for a tank transport vehicle. Background Technology

[0002] A moving tank, also known as a pallet jack or pallet yoke, is a heavy-duty equipment moving tool that replaces traditional rollers. It is widely used for moving small to medium-sized equipment and containers, combining high load-bearing capacity with ground protection. Moving tanks reduce operating resistance through rolling friction and utilize swivel casters or a remote control system for flexible steering. Some electric models are equipped with lithium batteries and wireless remote control functionality, allowing them to replace traditional rollers used in moving equipment. They are convenient, time-saving, and labor-saving, making them ideal tools for moving heavy equipment. Moving tanks can be used individually or in multiples. A single moving tank can move equipment weighing two to one hundred tons, while multiple moving tanks combined can move large equipment weighing four to six hundred tons. Moving tanks are heavy-duty moving devices that can replace traditional rollers used in moving equipment, offering convenience, time-saving, and labor-saving advantages, making them ideal tools for moving heavy equipment.

[0003] An existing type of tank transport vehicle, such as Figures 1-4 As shown, it includes a car body 1 and a load-bearing turntable 2. A tapered roller bearing 3 is embedded in the bottom surface of the load-bearing turntable. The rollers of the tapered roller bearing and the car body roll in contact. A composite bushing 4 is installed inside the car body. The load-bearing turntable is rotatably connected to the car body through a connecting shaft 5 passing through the composite bushing. This structure has the following defects: (1) The tapered roller bearing has poor load-bearing capacity, and the rollers of the tapered roller bearing are easily damaged under long-term load; (2) The rollers of the tapered roller bearing will wear down the load-bearing turntable and the car body after long-term rolling, resulting in the turntable not rotating flexibly; (3) It is difficult to ensure the horizontal consistency of the tapered roller bearing installation, resulting in uneven force on the tapered roller bearing and poor stability; (4) Disassembly and maintenance are inconvenient, especially the disassembly and assembly of the connecting shaft and the tapered roller bearing. Utility Model Content

[0004] This invention aims to solve the aforementioned problems existing in the load-bearing turntable installation structure of existing transport tank vehicles, and provides a transport tank vehicle turntable installation structure that is simple in structure, easy to disassemble and maintain, and has good stability and load-bearing capacity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A turntable mounting structure for transporting tanks according to the present invention includes a vehicle body and a load-bearing turntable. The load-bearing turntable is disposed above the vehicle body and can rotate relative to the vehicle body. The bottom surface of the load-bearing turntable is provided with an annular protrusion, and the vehicle body is provided with an annular groove. The annular protrusion and the annular groove are matched to the load-bearing turntable for radial positioning. A self-lubricating wear-resistant pad is sandwiched between the load-bearing turntable and the vehicle body. The invention of this utility model lies in the improved design of the installation structure of the load-bearing turntable. Through the cooperation of the annular protrusion and the annular groove, the radial limit of the load-bearing turntable and the rotation of the load-bearing turntable relative to the vehicle body are realized. The structure is simple and the disassembly and maintenance are very convenient. A self-lubricating wear-resistant gasket is sandwiched between the load-bearing turntable and the vehicle body. The self-lubricating wear-resistant gasket is used to bear the axial load. It has self-lubricating properties and can achieve long-term maintenance-free operation. At the same time, it can prevent wear and jamming caused by direct contact between the load-bearing turntable and the vehicle body. In addition, the self-lubricating wear-resistant gasket has a large contact area with the load-bearing turntable and the vehicle body, and the force is evenly distributed, which can improve the stability and load-bearing capacity of the load-bearing turntable. When the self-lubricating wear-resistant gasket is damaged, it is also very convenient to replace it.

[0006] Preferably, the bearing turntable is provided with screw holes, and fastening screws are installed in the screw holes. The fastening screws are threadedly connected to the vehicle body, axially limiting the bearing turntable to the vehicle body. By tightening and loosening the fastening screws, not only can the bearing turntable be axially limited to the vehicle body, making the bearing turntable and the vehicle body an integral part and preventing the bearing turntable from separating from the vehicle body, but the clamping force between the bearing turntable and the self-lubricating wear-resistant gasket can also be adjusted. The fastening screws are also very convenient to install and remove, making the disassembly and maintenance of the bearing turntable and the self-lubricating wear-resistant gasket very convenient. The screw holes and the annular protrusion are coaxially arranged.

[0007] Preferably, the annular protrusion and the annular groove are fitted with a clearance fit. This clearance fit reduces friction and wear between the annular protrusion and the annular groove.

[0008] Preferably, the annular protrusion and the bearing turntable are of the same material and are integrally formed.

[0009] Preferably, the thickness of the self-lubricating wear-resistant gasket is 1~2mm.

[0010] Preferably, the outer diameter of the self-lubricating wear-resistant pad is smaller than the diameter of the bearing turntable. This smaller outer diameter prevents the self-lubricating wear-resistant pad from being squeezed out of the bearing turntable under pressure.

[0011] Preferably, the self-lubricating wear-resistant gasket is a polytetrafluoroethylene gasket or a self-lubricating thrust gasket.

[0012] Therefore, this utility model has the following beneficial effects:

[0013] (1) By using the combination of the annular protrusion and the annular groove, the radial limit of the bearing turntable and the rotation of the bearing turntable relative to the vehicle body are realized. The structure is simple and easy to disassemble and maintain.

[0014] (2) A self-lubricating wear-resistant pad is sandwiched between the load-bearing turntable and the vehicle body. This not only prevents wear and jamming caused by direct contact between the load-bearing turntable and the vehicle body, but also improves the stability and load-bearing capacity of the load-bearing turntable. Furthermore, maintenance and replacement are very convenient. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 5-7The illustrated tank transport turntable mounting structure includes a vehicle body 1 and a load-bearing turntable 2. The load-bearing turntable is positioned above the vehicle body and has screw holes 9. These screw holes are stepped holes, and fastening screws 10 are installed inside the screw holes. The fastening screws are threadedly connected to the vehicle body, axially limiting the load-bearing turntable to the vehicle body (e.g., ...). Figure 8 , Figure 9 As shown), the load-bearing turntable can rotate relative to the vehicle body, and the bottom surface of the load-bearing turntable is provided with annular protrusions 6 (as shown). Figure 10 As shown), the annular protrusion and the bearing turntable are of the same material and are integrally formed. The annular protrusion and the annular groove are fitted with a clearance. The vehicle body is provided with an annular groove 7. The annular protrusion and the annular groove are fitted together to radially limit the bearing turntable. A self-lubricating wear-resistant pad 8 is sandwiched between the bearing turntable and the vehicle body. The self-lubricating wear-resistant pad is a 1.5mm thick polytetrafluoroethylene pad. The outer diameter of the self-lubricating wear-resistant pad is smaller than the diameter of the bearing turntable.

[0028] In this invention, the load-bearing turntable is positioned above the vehicle body. A ring-shaped protrusion and a ring-shaped groove are used to radially limit the turntable's movement while allowing it to rotate. A self-lubricating wear-resistant gasket is sandwiched between the turntable and the vehicle body. The turntable is connected to the vehicle body by fastening screws, which press the self-lubricating wear-resistant gasket firmly between them. This installation structure makes disassembly and maintenance of the turntable and the self-lubricating wear-resistant gasket very convenient; simply unscrewing the fastening screws is sufficient. The self-lubricating wear-resistant gasket, due to its self-lubricating properties, prevents wear and jamming caused by direct contact between the turntable and the vehicle body. Replacement of the self-lubricating wear-resistant gasket is also very convenient when damaged.

[0029] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
