Description

Technical Field

[0001] This utility model relates to the field of oil tank transportation technology, specifically a transformer oil tank transportation fixing device. Background Technology

[0002] Vehicles used for transporting small transformer oil tanks typically have a saddle structure on their cargo bed or main beam to support the bottom of the tank. This support structure effectively distributes the vertical load on the tank and the oil inside, ensuring the tank remains stable in static or smooth driving conditions. To prevent rolling or lateral displacement due to vehicle turning or tilting, existing technologies often use large clamps or flexible ropes to secure the tank circumferentially.

[0003] However, the existing method of fixing the tank will generate huge inertial impact forces on the tank and the oil inside when the vehicle faces emergency braking, frequent start and stop, or driving on continuous slopes. Since the circumferential clamps and rope structure mainly provide radial clamping force, its ability to restrict axial movement is weak. This may cause relative slippage between the tank and the saddle, which may not only wear down the contact area between the tank and the saddle, but also cause local impact on the vehicle structure, posing a safety hazard. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a transformer oil tank transportation and fixing device.

[0005] The technical solution of this utility model is as follows: A transformer oil tank transport fixing device is installed on the transport truck bed. Two sets of limiting seats are symmetrically arranged on the transport truck bed. The length direction of the limiting seats is consistent with the length direction of the transport truck bed. The opposite surfaces of the two sets of limiting seats form the installation position supporting the transformer oil tank with the upper end surface of the transport truck bed. Each of the two limiting seats is provided with a stop bar. The upper ends of the stop bar are provided with mounting grooves. The same side ends of the two stop bars are connected to a rotating limiting frame unit. The rotating limiting frame unit includes an integrally formed main stop bar and symmetrically arranged connecting rods at both ends. The end of the connecting rod away from the main stop bar is rotatably connected to the corresponding mounting groove. The connecting rod is adapted to the mounting groove, and the rotating limiting frame unit can rotate on the same side of the two stop bars. The mounting groove is provided with a clamping part that can press the main stop bar of the rotating limiting frame unit against the front or rear side of the transformer oil tank.

[0006] Preferably, the side of the limiting seat away from the installation position is provided with a stop bar protruding from its upper end face, and the two stop bars are parallel.

[0007] Preferably, the length direction of the mounting groove is consistent with the length direction of the stop bar, and the total length of the two mounting grooves on the same stop bar is not greater than 2 / 3 of the total length of the stop bar.

[0008] The connection structure between the connecting rod and the mounting groove is such that the connecting rod and the mounting groove are connected by a first hinge shaft, which is located at one end of the mounting groove near the middle of the stop bar.

[0009] The mounting position of the clamping member is such that a first storage groove is opened along the length of the mounting groove, the first storage groove is located on the bottom surface of the mounting groove away from the first hinge shaft, one end of the clamping member is rotatably mounted in the first storage groove through a second hinge shaft, and the second hinge shaft is located at the end of the first storage groove away from the first hinge shaft.

[0010] Furthermore, the lower end face of the connecting rod is provided with a clamping groove that is compatible with the clamping member.

[0011] To facilitate the storage of the rotation limiting frame unit when not in use and save space, a second storage groove is provided at the end of the stop bar away from the first hinge axis. The second storage groove is adapted to the main stop bar, the connecting rod is stored in the mounting groove, the clamping member is stored in the first storage groove, and the end part of the main stop bar is stored in the second storage groove.

[0012] Preferably, the stop bar is provided with a threaded hole that communicates with the mounting groove. A fastener is provided in the threaded hole. The fastener passes through the threaded hole and is threadedly connected to the connecting rod. After one clamping member clamps the main stop bar to the front side of the transformer oil tank and another clamping member clamps the rear side of the transformer oil tank, the connecting rod is further tightened by the clamping member to limit its movement and improve the overall stability of the rotation limit frame unit.

[0013] The beneficial effects of this utility model are as follows: By setting two sets of symmetrical rotating limiting frame units on the transport vehicle bed, the front and rear positions of the transformer oil tank can be limited by the rotating limiting frame units; after the tank is placed in the installation position, the frame unit can be operated to rotate around its hinge axis, so that its main stop bar is in contact with the front or rear face of the tank, which can effectively resist the inertial impact caused by sudden braking, acceleration and deceleration during transportation and prevent the tank from moving along its axial direction.

[0014] The rotating limiting frame unit adopts a rotating connection design, and with the tightening component set in the mounting slot, the limiting structure can have two states: working and retracted. In the working state, the tightening component can firmly press the main stop bar against the end face of the transformer oil tank. In the non-working state or when the tank needs to be loaded or unloaded, the rotating limiting frame unit can be rotated to a retracted position parallel to the stop bar and accommodated in the second storage slot. This avoids interference with the lifting operation of the tank, reduces the space occupied by the device, and improves the convenience and adaptability of use. Attached Figure Description

[0016] See Figure 1 , Figure 3 and Figure 4 As shown, a transformer oil tank transport fixing device is installed on a transport truck bed 1. Two sets of limiting seats 3 are symmetrically arranged on the transport truck bed 1. The length direction of the limiting seats 3 is consistent with the length direction of the transport truck bed 1. The opposing surfaces of the two sets of limiting seats 3 form an installation position supporting the transformer oil tank with the upper end surface of the transport truck bed 1. Each of the two limiting seats 3 is provided with a stop bar 2. The stop bar 2 is located on the side of the limiting seat 3 away from the installation position and protrudes from the upper end surface of the limiting seat 3. The two stop bars 2 are arranged in parallel. The two ends of the upper part of the stop bar 2 are provided with mounting grooves 201. The same side ends of the two stop bars 2 are connected to a rotating limiting frame unit 4.

[0017] The length direction of the mounting groove 201 is consistent with the length direction of the retaining bar 2. The total length of the two mounting grooves 201 on the same retaining bar 2 shall not exceed 2 / 3 of the total length of the retaining bar 2, so as to avoid the mounting groove 201 being too long and affecting the structural strength of the retaining bar 2. The retaining bar 2 can further limit the transformer oil tank.

[0018] See Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the rotating limiting frame unit 4 includes an integrally formed main stop rod 401 and connecting rods 402 symmetrically arranged at both ends. The end of the connecting rod 402 away from the main stop rod 401 is rotatably connected to the corresponding mounting groove 201. The connecting rod 402 and the mounting groove 201 are connected by a first hinge shaft 403, which is located at the end of the mounting groove 201 near the middle of the stop bar 2. The connecting rod 402 is adapted to the mounting groove 201, and the width of the connecting rod 402 is smaller than the width of the mounting groove 201, so that the connecting rod 402 can be housed in the mounting groove 201. The length of the connecting rod 402 is shorter than the length of the mounting groove 201. The mounting groove 201 is provided with a clamping member 5 that can press the main stop rod 401 against the front or rear side of the transformer oil tank.

[0019] The rotating limiting frame unit 4 adopts a rotating connection design and works in conjunction with the clamping member 5 set in the mounting groove 201, enabling the limiting structure to have two states: working and retracted. In the working state, the clamping member 5 can securely clamp the main stop bar 401 to the end face of the transformer oil tank. In the non-working state or when the tank needs to be loaded or unloaded, the rotating limiting frame unit 4 can be rotated to a retracted position parallel to the stop bar 2 and accommodated by the second retractable groove 204, thereby avoiding interference with the lifting operation of the tank, reducing the space occupied by the device, and improving the convenience and adaptability of use.

[0020] In this embodiment, a single rotating limiting frame unit 4 can rotate on the same side of the two stop bars 2. With the cooperation of the clamping member 5, one rotating limiting frame unit 4 clamps the front side of the transformer oil tank, and the other rotating limiting frame unit 4, with the clamping member 5, clamps the rear side of the transformer oil tank, thereby achieving the limiting effect in the axial direction of the transformer oil tank. This can effectively resist the inertial impact caused by sudden braking, acceleration and deceleration during transportation and prevent the tank from moving along its axial direction.

[0021] See Figure 5 As shown, the installation position of the clamping member 5 is as follows: the mounting groove 201 has a first storage groove 203 along its length direction. The first storage groove 203 is located on the bottom surface of the mounting groove 201 away from the first hinge shaft 403. One end of the clamping member 5 is rotatably set in the first storage groove 203 through the second hinge shaft 6. The second hinge shaft 6 is located at the end of the first storage groove 203 away from the first hinge shaft 403. The lower end face of the connecting rod 402 is provided with a clamping groove 4021 that is adapted to the clamping member 5. The other end of the clamping member 5 can be engaged in the clamping groove 4021 when the connecting rod 402 needs to be supported.

[0022] To facilitate the storage of the rotation limiting frame unit 4 when not in use and save space, a second storage groove 204 is provided at the end of the stop bar 2 away from the first hinge shaft 403. The second storage groove 204 is adapted to the main stop bar 401. The connecting rod 402 is stored in the mounting groove 201, the clamping member 5 is stored in the first storage groove 203, and the end part of the main stop bar 401 is stored in the second storage groove 204.

[0023] See Figure 2 and Figure 5 As shown, the stop bar 2 has a threaded hole 202 communicating with the mounting groove 201. A fastener 7, which can be a bolt, is installed inside the threaded hole 202. The fastener 7 is threadedly connected to the threaded hole 202 and passes through the threaded hole 202 to be threadedly connected to the connecting rod 402. After one clamping member 5 clamps the main stop rod 401 against the front side of the transformer oil tank, and another clamping member 5 clamps the rear side of the transformer oil tank, the connecting rod 402 is further tightened by the clamping members 5, limiting its movement and improving the overall stability of the rotation limiting frame unit 4. The auxiliary fastener 7 applies additional locking force to the connecting rod 402 after the clamping members 5 have completed the initial clamping, achieving double locking of the rotation limiting frame unit 4, effectively preventing loosening that may occur under long-term vibration, and enhancing the overall structural stability.
