Description

Technical Field

[0001] The invention relates to the field of transportation and mechanical technology, and in particular to a method for rolling a tank container at a fixed angle. Background Art

[0002] With the continuous development of the freight market, more and more liquid, powder, and liquid-solid mixture products need to be transported or stored in tank containers, such as paint, fuel (ethanol gasoline), chemical reagents, etc. Most of these fluid products are mixtures and therefore lack long-term stability. If they are kept in the same position for a long time during transportation or storage, it is easy to cause precipitation and stratification, which will change the quality of the goods. In most cases, we must ensure the stable, reliable, and safe transportation and storage of products, and regularly roll the products in the container slowly to a specific angle, which puts higher requirements on related transportation equipment.

[0003] Although traditional commercial concrete transport trucks (cement tank trucks) can achieve the rolling of products in the tank, there are also many problems: first, the rotation speed is too fast and the rotation angle is difficult to accurately control; second, the motor, wires and other auxiliary equipment are very close to the tank body, which poses a great safety hazard for some flammable and explosive products; third, the tank body and the vehicle body are fixed together and cannot be separated, the equipment cost is high, and the utilization rate and efficiency are low. The search also found that similar transportation devices also include Chinese patents CN208645687U, CN210191296U, CN204641516U, etc., and these devices still have the above problems. Summary of the invention

[0004] In order to overcome the above problems existing in the prior art, the present invention provides a tank container rolling support vehicle device and a corresponding rolling operation method, which ultimately achieves the purpose of rolling the tank and its internal products at a fixed angle conveniently, quickly and safely. The technical solution adopted by the present invention is as follows:

[0005] A method for rolling a tank container at a fixed angle comprises the following steps: (a) fixing a front clamp 5 and a rear clamp 6 at both ends of a tank body 1 and locking them, fixing a lifting shaft 12 to the tank body and locking them, and fixing a lifting rope to the lifting shaft 12; (b) lifting the tank body 1 onto a front support seat 3 and a rear support seat 4 of a plane frame 2 by means of a lifting rope, so that the front and rear clamps are respectively pressed onto supporting rollers 7 on the arc-shaped surfaces of the front and rear support seats, and removing the lifting shaft and the lifting rope; (c) using two pieces of material with a certain angle (referring to a fixing connecting plate and a fixing connecting plate) to fix the tank body 1 to the front support seat 3 and the rear support seat 4 of a plane frame 2, and removing the lifting shaft and the lifting rope; The connecting and fixing plate 8 (the angle formed by the connecting line of the center of the tank body in the same plane, the specific angle is 90°) fixes the clamp and the corresponding bracket, thereby locking the tank body; (d) when the tank body needs to be rolled, remove the bolts on the connecting and fixing plate 8 close to the clamp, install the rolling handle on the clamp, and rotate the rolling handle to drive the tank body 1 to rotate a specific angle (such as 90°) on the supporting roller 7, so that the screw holes on the clamp are aligned with the screw holes on the connecting and fixing plate, install the bolts to lock the tank body, and remove the rolling handle at the same time.

[0006] Furthermore, the rolling method of the can body in step (d) is as follows: the first step is to roll the can body four times in one direction, each time rolling 90°; the second step is to roll the can body four times in the opposite direction, each time rolling 90°; the third step is to repeat the first and second steps. In production practice, the product in the can body is required to roll once (90°) at an interval. First, it is rolled four times in one direction (such as clockwise) to complete a 360° roll. Due to the rotation, the can body will have a displacement in the front and back directions. If it keeps rolling in one direction, this displacement will continue to accumulate and become larger and larger, and eventually deviate from the correct support position. Therefore, after rolling 360°, the can body rolls four times in the opposite direction (counterclockwise) to return to the original position. The axial displacement of the can body is offset or eliminated by flipping forward and backward, ensuring that the support position remains unchanged.

[0007] Furthermore, four screw holes are evenly distributed along the circumference on the surface of the front clamp 5 and the rear clamp 6. These four screw holes ensure that the tank body can only roll at an angle of 90° each time, so that it can be reliably locked on the bracket.

[0008] Furthermore, at least one tool box 10 is provided on the surface of the plane frame 2 , and disassembled parts such as lifting ropes and lifting shafts can be stored in the tool box 10 .

[0009] Furthermore, at least three groups of supporting rollers 7 are disposed on the arc-shaped surfaces of the front supporting seat 3 and the rear supporting seat 4 .

[0010] Furthermore, the front clamp 5 and the rear clamp 6 each include an upper clamp, a lower clamp and a fastening bolt.

[0011] Furthermore, before the front clamp 5 and the rear clamp 6 are fixed to the tank body 1, an anti-sliding block 11 (toothed rubber plate) needs to be bonded to the inner surface of the clamp in advance. The anti-sliding block can increase the friction force to prevent the tank body from slipping, and can also protect the supporting part of the tank body from deformation under stress.

[0012] Furthermore, traction hooks are provided at both the front and rear ends of the plane frame 2, and single-rim wheel sets 9 are provided at the bottom of both the left and right sides of the plane frame 2; the traction hooks are connected to the traction ropes, and the single-rim wheel sets 9 are clamped on the track, and the traction ropes can be pulled to drive the plane frame 2 and the tank body to slide along the track. This design is conducive to the transportation and transfer of the tank body and is convenient for loading and unloading.

[0013] Compared with the prior art, the method of the present invention has the following beneficial effects: (1) the purpose of rolling the tank body to a specific angle is achieved by the cooperation of the four screw holes evenly distributed on the clamp and the connecting fixing plate; (2) the tank body rolls in a special manner of rotating forward four times and then reversely four times or reversely four times and then rotating forward four times, which can offset the displacement of the tank body caused by the rotation, thereby ensuring the relative fixation of the supporting parts and the reliability of the support; (3) the tank body does not have to be mounted on the vehicle body and can be used alone or in combination with a flatbed trailer or a large storage and transportation box, which is more flexible and more efficient; (4) good safety, high reliability and low cost.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to fully understand the technical solutions and beneficial effects of the present invention, further description is given below in conjunction with specific embodiments.

[0021] like Figure 1-5The tank container rolling support frame shown in the figure has a tank body 1, a plane frame 2, a front support seat 3 and a rear support seat 4 as the main body. The plane frame 2 is welded by a 100×50×4mm rectangular steel pipe, and its appearance is similar to a flat base. A positioning seat is provided at the front end of the plane frame 2, a fixing seat is provided at the rear end, and a traction hook is provided at both the front and rear ends of the plane frame. In addition, five sets of single-rim wheel groups 9 are provided on the left and right sides of the plane frame 2, respectively, so that the entire tank body can slide in and out along the track under the traction of the wire rope. The front support seat 3 and the rear support seat 4 are cast by steel, and the width of the support seat is about 200mm. The two are welded parallel to the upper surface of the plane frame 2 at a certain distance. Four sets of support rollers 7 are evenly arranged on the arc surface of the front and rear support seats to realize the rolling of the tank body. The tank body is not directly placed on the arc of the front and rear support seats, but is rolled and fixed with the help of front and rear clamps. The front clamp 5 and the rear clamp 6 are both made of an upper clamp and a lower clamp, and an anti-sliding block 11 (a finished toothed rubber plate) with a thickness of about 15 mm is also bonded to the inner surface of the clamp. The two ends of the tank body 1 are fixed by the front clamp 5 and the rear clamp 6 respectively, and are restricted by the anti-sliding block to prevent sliding. Then the tank body is hung on the plane frame 2 through the lifting shaft 12, so that the front and rear clamps are in contact with the curved surfaces of the front and rear brackets respectively, and the two ends of the two connecting and fixing plates 8 with a 90° angle are fixed to the clamps and the brackets respectively with screws (a total of 4 connecting and fixing plates in the front and rear groups). When the tank body needs to be rotated, loosen the bolts of the connecting and fixing plates 8 close to one end of the clamps, hold the handle on the clamps to apply a rolling torque, and the tank body stops after rotating 90° clockwise or counterclockwise, insert the bolts into the connecting and fixing plates 8 and tighten them, and lock the tank body and the bracket again.

[0022] The specific process of using the above equipment to roll the tank at a fixed angle is as follows:

[0023] Step 1: First, glue several anti-sliding blocks 11 to the inner surfaces of the upper and lower clamps of the front and rear clamps, and then respectively put the two sets of upper and lower clamps on the preset positions of the tank body 1, and then fix the upper and lower clamps with bolts. Fix four sets of lifting shafts 12 on the front and rear sides of the tank body 1, and tie the wire ropes to the lifting shafts.

[0024] Step 2: Fix the lifting rope on the lifting equipment, and use the lifting rope to lift the tank body 1 onto the front support seat 3 and the rear support seat 4 of the plane frame 2, ensuring that the front and rear clamps are in contact with and pressed against the support rollers 7 on the curved surfaces of the front and rear support seats, and remove the lifting shaft and lifting rope. Fix the two connecting and fixing plates 8 to the support seats at an angle of 90° (both the front and rear support seats are installed), install the rolling handle into the screw holes on the surface of the front and rear clamps, and turn the rolling handle to drive the tank body 1 to roll on the support rollers 7, so that the screw holes on the front and rear clamps are aligned with the screw holes at the ends of the front and rear two sets of connecting and fixing plates 8, and use bolts to lock the clamps with the corresponding support seats to complete the fixation of the tank body, and remove the rolling handle. At this point, the installation and locking of the tank body are completed, and the entire equipment can be stored on site or loaded and transported.

[0025] Step 3: Remove the bolts on the side of the connecting plate 8 close to the clamp, install the rolling handle on the clamp, turn the rolling handle to drive the tank body 1 to rotate 90° clockwise on the supporting roller 7. At this time, the screw holes on the connecting plate are aligned with the screw holes on the clamp, install the bolts to lock the clamp and the bracket (the tank body is also locked), and remove the rolling handle.

[0026] Step 4: When the next preset rolling time comes, continue to roll the tank 90° clockwise according to the above operation. When the tank has been turned clockwise 4 times (a total of 360°), roll the tank 90° counterclockwise at each set time until it returns to the original position after 4 times. Repeat the above process for subsequent rolling, that is, roll 4 times clockwise-roll 4 times counterclockwise in a cycle.
