Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0025] Embodiment 1

[0026] The utility model fixes the oil tank on the carrier frame 1 through the arc rod 32 and the limit member 4 to prevent it from falling due to shaking during transportation; moreover, the arc rod 32 can be retracted into the arc chute 31, so that the oil tank will not be restricted by the overly long arc rod 32 during installation and disassembly, which facilitates disassembly and assembly.

[0027] like Figure 1-3 As shown, a special trailer frame for underground oil tanks includes a load-bearing frame 1 and a traction frame 2 arranged on one side of the load-bearing frame 1. At least three groups of support seats 3 and two limit members 4 are arranged on the load-bearing frame 1. The support seat 3 is located between the two limit members 4. The upper surface of the support seat 3 is a curved surface structure. Two arc-shaped slide grooves 31 with opposite opening directions are provided inside the support seat 3, and an arc-shaped rod 32 is slidably installed in the arc-shaped slide groove 31. One end of the arc-shaped rod 32 extends from the opening of the arc-shaped slide groove 31. Fixing devices 33 for fixing the arc-shaped rod 32 are arranged on both sides of the support seat 3. Arc-shaped rods 32 extend from both sides of the support seat 3 to fix the oil tank. The arc-shaped rod 32 can prevent the oil tank from shaking left and right, and the limit member 4 can prevent the oil tank from shaking back and forth.

[0028] Furthermore, at least three grooves 321 are formed on the side surface of one end of the arc rod 32 located in the arc chute 31. Each groove 321 can be engaged with a locking rod 332 described below, thereby controlling the length of the arc rod 32 extending out of the arc chute 31. The structural shape of the arc rod 32 is conducive to adhering to the outer wall of the oil tank.

[0029] like Figure 4-5As shown, further, the fixing device 33 includes a housing 331 connected to the inside of the arc-shaped slide groove 31. A spring groove 3311 is provided in the housing 331. A locking rod 332 and a spring 333 are installed in the spring groove 3311. One end of the locking rod 332 is connected to one end of the spring groove 3311 through the spring 333, and the spring 333 pushes the locking rod 332 into the inside of the arc-shaped slide groove 31 and engages with the groove 321.

[0030] Furthermore, a handle 3321 is provided at one end of the locking rod 332 away from the arc-shaped slide groove 31, and the handle 3321 extends out of the shell 331. The spring groove 3311 is provided with a window 33111 for moving the handle 3321 from the inside to the outside, and the locking rod 332 is moved out of the groove 321 by pulling the handle 3321. When the oil tank needs to be adjusted or unloaded, the operator only needs to pull the handle 3321 to overcome the elastic force of the spring 333 and pull the locking rod 332 out of the groove 321, so that the arc-shaped rod 32 can move freely in the arc-shaped slide groove 31, which is convenient for the installation or removal of the oil tank. This design not only ensures the firm fixation of the oil tank, but also greatly simplifies the loading and unloading process and improves efficiency.

[0031] Furthermore, the fixing device 33 is close to the opening of the arc-shaped slide groove 31, so that the length of the arc-shaped rod 32 that can be moved out of the arc-shaped slide groove 31 is maximized, and the fixing effect on the oil tank is better.

[0032] like Figure 6 As shown, further, two limit members 4 are symmetrically arranged on both sides of the support frame 1. Each limit member 4 includes a fixing plate 41 and an arc groove 42, and the oil tank is installed on the arc groove 42.

[0033] Furthermore, one end of the arc rod 32 located outside the arc chute 31 is rotatably connected to a pulley 322. The pulley 322 moves in close contact with the outer wall of the oil tank, facilitating the movement of the arc rod 32.

[0034] Working principle:

[0035] During installation, place the oil tank on the support seat 3 and the stopper 4, then pull the arc rod 32 out of the arc slot 31, and the pulley 322 installed on the arc rod 32 rolls along the outer wall of the oil tank. When the locking rod 332 is first engaged with the groove 321, observe whether the length of the arc rod 32 is sufficient to fix the oil tank. If not, pull the handle 3321 to move the locking rod 332 out of the groove 321, release the fixation of the fixing device 33 and the arc rod 32, and continue to pull the arc rod 32 out of the arc slot 31 until the length is appropriate. Figure 7Through the above steps, the oil tank is safely and effectively installed on the trailer frame, which not only solves the safety hazards caused by the traditional fixing method, but also ensures the stability of the oil tank during transportation, and is convenient for quick loading and unloading, thereby improving work efficiency.

[0036] During disassembly, it is only necessary to release the fixing of the fixing device 33 and the arc rod 32 and retract the arc rod 32 into the arc sliding groove 31 .
