Description

A method of rolling a tank container at a fixed angle

technical field

The invention relates to the technical fields of transportation and machinery, in particular to a method for rolling a tank container at a fixed angle.

Background technique

With the continuous development of the freight market, more and more liquid, powder, and liquid-solid mixture products need to be transported or stored through tank containers, such as coatings, fuels (ethanol gasoline), chemical reagents, etc. Most of these fluid products are mixtures and thus have insufficient long-term stability. During transportation or storage, if the same posture is maintained for a long time, precipitation and stratification are likely to occur, which will change the quality of the products. In most cases, we not only need to ensure the stable, reliable and safe transportation and storage of the product, but also regularly roll the product in the container slowly to a certain angle, which puts forward higher requirements for the relevant transportation equipment.

Although the traditional commodity concrete transport vehicle (cement tanker) can realize the rolling of the products in the tank, there are also many problems: one is that the rotation speed is too fast, and the rotation angle is difficult to control accurately; Recently, for some flammable and explosive products, there is a big safety hazard; 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. These devices still have the above problems.

SUMMARY OF THE INVENTION

In order to overcome the above-mentioned problems existing in the prior art, the present invention provides a tank container rolling support carriage device and a corresponding rolling operation method, which finally realizes the rolling and fixing of the tank body and its internal products conveniently, quickly and safely. angle of purpose. The technical scheme adopted in the present invention is as follows:

A method for rolling a tank container at a fixed angle, comprising the following steps: (a) respectively fixing the front clamp 5 and the rear clamp 6 on both ends of the tank body 1 and locking them, and fixing the hoisting shaft 12 to the tank body (b) The tank body 1 is hoisted onto the front bracket 3 and the rear bracket 4 of the plane frame 2 through the sling, so that the front and rear clamps are respectively pressed on the On the support roller 7 on the arc-shaped surface of the front and rear brackets, remove the hoisting shaft and the sling; (c) use two pieces to form a certain angle (refer to the angle formed by the connection between the fixed connecting plate and the center of the tank in the same plane, specifically The connection fixing plate 8 with an angle of 90°) fixes the clamp with the corresponding bracket, thereby locking the tank body; (d) when the tank body needs to be rolled, remove the connection fixing plate 8 close to the clamp side. Bolts, install the rolling handle on the clamp, turn the rolling handle to drive the tank 1 to rotate on the support roller 7 by a specific angle (such as 90°), so that the screw holes on the clamp are aligned with the screw holes on the connection fixing plate , install the bolt to lock the tank, and remove the rolling handle at the same time.

Further, the rolling mode of the tank body in step (d) is specifically as follows: the first step rolls the tank body successively 4 times in one direction, and each time rolls 90°; the second step rolls the tank body successively in the opposite direction. Turn 4 times, rolling 90° each time; repeat steps 1 and 2 for the third step. In production practice, the product in the tank is faced with the requirement of rolling once (90°) at intervals, firstly rolling 4 times in one direction (such as clockwise) and then completing the 360° rolling. Due to the rotation effect, the tank will have a displacement in the front and rear directions. If it keeps rolling in one direction, this displacement will continue to superimpose and eventually deviate from the correct support position. Therefore, the tank will reverse again after rolling 360°. The direction (counterclockwise) is rolled 4 times to return to the original position, and the axial displacement of the tank body is offset or eliminated by the positive and negative inversion, and the support position is kept unchanged.

Further, four screw holes are evenly distributed on the surfaces of the front clamp 5 and the rear clamp 6 along the circumference. These 4 screw holes ensure that the roll angle of the tank can only be 90° each time, so that it can be reliably locked on the bracket.

Further, at least one tool box 10 is provided on the surface of the plane frame 2 , and the disassembled suspending ropes, lifting shafts and other components can be stored in the tool box 10 .

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

Further, the front clamp 5 and the rear clamp 6 both include an upper clamp, a lower clamp and a fastening bolt.

Further, before the front clamps 5 and the rear clamps 6 are fixed to the tank body 1 , it is necessary to bond the anti-skid blocks 11 (toothed rubber plates) on the inner surfaces of the clamps in advance. The anti-skid block can increase the friction force to prevent the tank body from slipping, and can also protect the support part of the tank body to prevent it from being deformed by force.

Further, the front and rear ends of the plane frame 2 are provided with towing hooks, and the bottoms of the left and right sides of the plane frame 2 are provided with single rim wheel sets 9; the traction hook is connected with the traction rope, and the single rim The wheel group 9 is clamped on the track, and pulling the traction rope can drive the plane frame 2 and the tank to slide along the track. This design facilitates the transport and transfer of the tank, and facilitates loading and unloading.

Compared with the prior art, the method of the present invention has the following beneficial effects: (1) through the cooperation of the four screw holes evenly distributed on the clamp and the connection and fixing plate, the purpose of rolling the tank at a specific angle is realized; (2) The tank body rolls in a special way of forward rotation 4 times and then reverse rotation 4 times or reverse rotation 4 times and forward rotation 4 times, which can offset the displacement of the tank body caused by the rotation, and ensure the relative fixation of the support part and the reliability of the support; (3) The tank does not need to be mounted on the car body, and can be used alone or in combination with a flatbed trailer and a large storage and transportation box, which is more flexible and more efficient; (4) It has good safety, high reliability and low cost.

The front end of the plane frame 2 is provided with a positioning seat, the rear end is provided with a fixed seat, and the front and rear ends of the plane frame 2 are provided with traction hooks. In addition, five sets of single-rim wheel sets 9 are arranged on the left and right sides of the plane frame 2, so that the entire tank body can slide in and out along the track under the traction of the wire rope. The front bracket 3 and the rear bracket 4 are made of steel casting, the bracket width is about 200mm, and the two are parallel welded on the upper surface of the plane frame 2 at a certain distance. Four groups of support rollers 7 are evenly arranged on the curved surfaces of the front and rear brackets to realize the rolling of the tank. The tank body is not directly placed on the arc of the front and rear brackets, but is rolled and fixed with the help of front and rear clamps. The front clamp 5 and the rear clamp 6 are formed by splicing the upper clamp and the lower clamp, and the inner surface of the clamp is also bonded with an anti-skid block 11 (toothed rubber plate finished product) with a thickness of about 15 mm. The two ends of the tank body 1 are respectively fixed by the front clamp 5 and the rear clamp 6, and are restricted from sliding by the anti-skid block, and then the tank body is hoisted on the plane frame 2 by the lifting shaft 12, so that the front and rear clamps are respectively Contact with the arc surfaces of the front and rear brackets, and use screws to fix the two ends of the two connecting and fixing plates 8 with an included angle of 90° to the clamp and the bracket respectively (a total of 4 connecting and fixing plates in the front and rear groups). When it is necessary to rotate the tank body, loosen the bolt on the end of the connection fixing plate 8 near the clamp, hold the handle on the clamp to apply a rolling torque, turn the tank clockwise or counterclockwise 90° and stop, insert the bolt into the connection fixing plate 8 and tighten, and lock the can body and the bracket again.

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

Step 1: First, glue several anti-skid blocks 11 on the inner surfaces of the upper and lower clamps of the front and rear clamps, then place the two sets of upper and lower clamps at the preset positions of the tank body 1 respectively, and then bolt the The upper and lower clamps are fixed. Four sets of hoisting shafts 12 are respectively fixed on the front and rear sides of the tank body 1, and the wire ropes are tied on the hoisting shafts.

Step 2: Fix the sling on the lifting equipment, and hoist the tank 1 to the front bracket 3 and the rear bracket 4 of the plane frame 2 through the sling to ensure that the front and rear clamps and the curved surface of the front and rear brackets are The supporting rollers 7 are contacted and pressed, and the hoisting shaft and suspending rope are removed. Fix the two connecting and fixing plates 8 to the brackets at a 90° angle (both the front and rear brackets 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 support Roll on the roller 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 groups of connection fixing plates 8, and the clamps and the corresponding brackets are locked with bolts to complete the fixation of the tank body. handle. At this point, the installation and locking of the tank is completed, and the entire equipment can be stored on site or transported by truck.

Step 3: Remove the bolts on the side of the connection fixing plate 8 close to the clamp, install the rolling handle on the clamp, turn the rolling handle to drive the tank 1 to rotate 90° clockwise on the support roller 7, and then connect The screw holes on the fixing plate are aligned with the screw holes on the clamp, install bolts to lock the clamp and the bracket (the tank is also locked), and remove the rolling handle.

Step 4: After the next preset rolling time, continue to roll the tank 90° clockwise with reference to the above operation. When the can body is turned clockwise 4 times (360° in total), the can body is then rolled counterclockwise by 90° every set time until it returns to the original position after 4 times. The above process can be repeated for the subsequent rolling, that is, the clockwise rolling is performed 4 times and the counterclockwise rolling is performed 4 times.
