Method for rolling tank container to fix angle

Technical Field

The invention relates to the technical field of transportation and machinery, in particular to a method for fixing an angle of a tank container in a rolling manner.

Background

With the development of the freight market, more and more liquid, powder and liquid-solid mixture products need to be transported or stored by tank containers, such as paint, fuel (ethanol gasoline), chemical reagents and the like. Most of the fluid products are mixtures, so that the long-term stability is insufficient, and the phenomena of sedimentation, layering and the like are easy to occur if the same posture is kept for a long time in the transportation or storage process, so that the quality of the commodities is changed. In most cases, the product is required to be stably, reliably and safely transported and stored, and the product in the container is required to be slowly rolled at a specific angle at regular intervals, which puts higher requirements on related transportation equipment.

Although the traditional commercial concrete transport vehicle (cement tank car) can realize the rolling of products in the tank, the traditional commercial concrete transport vehicle also has a plurality of problems: firstly, the rotating speed is too high, and the rotating angle is difficult to accurately control; the auxiliary equipment such as the motor, the electric wire and the like is very close to the tank body, so that large potential safety hazards exist for certain flammable and explosive products; thirdly, the tank body and the vehicle body are fixed together and can not be separated, the equipment cost is higher, and the utilization rate and the efficiency are lower. It was found that similar transportation devices also include chinese patents CN208645687U, CN210191296U, CN204641516U, etc., and the above problems still exist in these devices.

Disclosure of Invention

In order to overcome the problems in the prior art, the invention provides tank container rolling support trolley erecting equipment and a corresponding rolling operation method, and finally, the aim of conveniently, quickly and safely realizing the rolling fixed angle of a tank and a product inside the tank is fulfilled. The technical scheme adopted by the invention is as follows:

a method for rolling a tank container at a fixed angle, comprising the steps of: (a) respectively fixing a front clamp 5 and a rear clamp 6 at two ends of the tank body 1 and locking, fixing a lifting shaft 12 on the tank body and locking, and fixing a lifting rope on the lifting shaft 12; (b) the tank body 1 is lifted to the front support seat 3 and the rear support seat 4 of the plane frame 2 through lifting ropes, so that the front hoop and the rear hoop are respectively pressed on the support rollers 7 on the arc surfaces of the front support seat and the rear support seat, and the lifting shaft and the lifting ropes are removed; (c) two connecting and fixing plates 8 which form a certain included angle (the included angle formed by the fixed connecting plate and the connecting line of the circle centers of the tank bodies in the same plane, the specific angle is 90 degrees) are used for fixing the hoop and the corresponding bracket, so that the tank bodies are locked; (d) when the tank body needs to be rolled, the bolt on one side, close to the hoop, of the connecting and fixing plate 8 is detached, the rolling handle is installed on the hoop, the rolling handle is rotated to drive the tank body 1 to rotate on the supporting roller 7 by a specific angle (such as 90 degrees), so that the screw hole in the hoop is aligned with the screw hole in the connecting and fixing plate, the bolt is installed to lock the tank body, and the rolling handle is detached simultaneously.

Further, the rolling mode of the tank body in the step (d) is specifically as follows: firstly, rolling the tank body for 4 times along one direction, wherein the rolling is carried out for 90 degrees each time; secondly, rolling the tank body for 4 times in the opposite direction, wherein the rolling is carried out for 90 degrees each time; and thirdly, repeating the operations of the first step and the second step. In production practice, the product in the tank is subjected to a requirement to roll once (90) at intervals, first 4 times in one direction (e.g. clockwise) and then just a 360 roll. Because the tank body has a displacement in the front-rear direction under the rotating action, if the tank body rolls towards a direction all the time, the displacement is continuously superposed and is gradually increased and finally deviates from the correct supporting position, so that the tank body rolls for 4 times in the reverse direction (anticlockwise) again to return to the initial position after rolling for 360 degrees, the axial displacement of the tank body is offset or eliminated through positive and negative overturning, and the supporting position is ensured to be unchanged.

Furthermore, 4 screw holes are uniformly distributed on the surfaces of the front clamp 5 and the rear clamp 6 along the circumference. The 4 screw holes ensure that the tank body can be reliably locked on the bracket only when the rolling angle of the tank body is 90 degrees each time.

Further, at least one tool box 10 is disposed on the surface of the planar frame 2, and the detached components such as the lifting rope and the lifting shaft can be stored in the tool box 10.

Further, at least 3 groups of supporting rollers 7 are arranged on the arc surfaces of the front bracket 3 and the rear bracket 4.

Further, preceding clamp 5 and back clamp 6 all include last clamp, lower clamp and fastening bolt.

Furthermore, before the front clamp 5 and the rear clamp 6 are fixed with the tank body 1, an anti-skid block 11 (a tooth-shaped rubber plate) needs to be adhered to the inner surface of the clamps in advance. The non-slip blocks can increase the friction force to prevent the tank body from slipping, and can also protect the supporting part of the tank body from being deformed under stress.

Furthermore, the front end and the rear end of the plane frame 2 are both provided with a traction hook, and the bottoms of the left side and the right side of the plane frame 2 are both provided with a single-wheel-rim wheel set 9; the traction hook is connected with a traction rope, the single-wheel-rim wheel set 9 is clamped on the rail, and the plane frame 2 and the tank body can be driven to slide along the rail by pulling the traction rope. The design is beneficial to the transportation and transfer of the tank body and is convenient for loading and unloading.

Compared with the prior art, the method has the following beneficial effects: (1) 4 screw holes uniformly distributed on the hoop are matched with the connecting fixing plate, so that the purpose of rolling the tank body at a specific angle is achieved; (2) the tank body rolls according to a special mode of rotating forwards for 4 times and then rotating backwards for 4 times or rotating backwards for 4 times and then rotating forwards for 4 times, so that the displacement of the tank body caused by rotation can be counteracted, and the relative fixation of the supporting part and the supporting reliability are ensured; (3) the tank body does not need to be carried on a vehicle body, can be used independently or combined with a flat trailer and a large storage and transportation box, and is more flexible and higher in efficiency; (4) high safety, high reliability and low cost.
