Description

Hydraulic lifting tank transport and loading and unloading frame

technical field

The utility model relates to a tank loading and unloading device, in particular to a professional device for land vehicles loading and unloading tanks.

Background technique

Tank filling and vehicle transportation are common land transportation methods for liquid materials such as liquefied petroleum gas, gasoline and diesel, and sulfuric acid. At present, the transportation of tanks is mainly dragged by semi-trailer carriages, and the tanks are fixed on specific carriages with supporting legs and wheels, which cannot be easily separated. In this way, each tank needs to be equipped with a special carriage, which not only reduces the vehicle utilization rate, but also takes up more funds and resources, and increases the cost. In addition, the loading and unloading of tanks requires special lifting equipment, which not only requires increased investment, but also affects the efficiency of vehicles due to the failure to complete timely loading and unloading.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a loading and unloading device for tank transportation. Features to meet market needs.

The technical solution adopted by the utility model is: hydraulic lifting tank transport loading and unloading frame, which is characterized in that the loading and unloading frame includes a load-bearing frame for bearing the weight of the tank and arranged horizontally, supporting legs installed at the four corners of the load-bearing frame, driving The hydraulic lifting mechanism for vertical lifting of the load-bearing frame and the translation mechanism for adjusting the horizontal displacement of the supporting legs.

The supporting legs include two vertically positioned inner cylinders and outer cylinders that are fitted into each other and can slide with each other.

The hydraulic lifting mechanism is as follows: the cylinder body of the oil cylinder is installed in the inner cavity of the outer cylinder of the supporting leg, the top of the piston rod of the oil cylinder extends downward into the inner cavity of the inner cylinder and is fixed with the bottom of the inner cylinder, and the wall of the outer cylinder An oil pipe joint communicating with the cylinder body of the oil cylinder is installed on the outside, and another oil pump inputs or extracts hydraulic oil through the oil pipe joint to realize relative sliding between the inner cylinder and the outer cylinder.

The translation mechanism is: the upper end of each support leg is respectively fixed on a horizontally arranged sliding shaft, and the sliding shaft is inserted into a suitable sleeve for sliding fit; all the sleeves are respectively fixed on the left and right sides of the load-bearing frame ends.

The working principle of the utility model is: when the vehicle needs to load the tank 14, the sliding shaft 2 fixed with the upper end of the supporting leg extends out the maximum distance laterally from the sleeve 3-1 (as shown in Figure 5), and the fixing frame of the positioning tank 13 Place it above the load-bearing frame 3 (direction A) by a hoisting machine, and the bottom ends of the four corners of the fixed frame are fixed on the load-bearing frame by fasteners (generally, the boss 3-2 passes upward through the opening at the bottom of the fixed frame Finally, fix the bolt on the boss to fix the fixed frame); at this time, the driver reverses the vehicle 12 (usually a semi-trailer compartment) (direction shown by arrow B in Figure 6) to the bottom of the loading and unloading frame, and then puts the The oil pipe of the oil pump is connected to the oil pipe joint, and the oil pump is started to release the hydraulic oil (or the oil pipe joint is opened to release the hydraulic oil directly) so that the support leg 1 shrinks, and the loading and unloading frame is slowly lowered until the loading and unloading frame contacts the designated position of the vehicle bearing surface. After the gravity of the loading and unloading rack falls on the vehicle completely, the operator can pack up the supporting legs 1, and reinforce the connection between the loading and unloading rack and the vehicle (as shown in Figure 7), and then transport the tank away. The process of retracting the supporting leg 1 is as follows: first control the supporting leg 1 to rotate around the sleeve 3-1 (at this time, the pin 6-2 needs to be pulled out first, and the gland 6 is removed to eliminate the obstacle of the lateral sliding of the tendon rod 5) , indirectly drives the tendon rod 5 to rotate, so that the tendon rod 5 moves along the chute 3-3 on the beam until the supporting leg 1 rotates to a horizontal state, and finally pushes the sliding shaft 2 to retract it into the sleeve 3-1. This completes the entire loading process.

The unloading process of the tank is the reverse process of the above process.

The beneficial effect of the utility model is: because the special loading and unloading rack is configured, the operator can load the tank on the vehicle or unload the tank from the vehicle by manipulating the relevant parts on the loading and unloading rack; there is no need to use lifting machinery , so that the utilization rate of the delivery vehicle has been significantly improved, saving investment and reducing costs. Moreover, the loading and unloading rack has the characteristics of excellent mechanical properties, labor-saving and convenient operation, and high safety in use, which can effectively improve the efficiency of transportation enterprises, reduce labor intensity of workers, and promote the development of tank transportation industry.

Detailed ways

As shown in Figure 1, in the hydraulic lifting tank transport and loading frame, there is a load-bearing frame 3 arranged horizontally for carrying the weight of the tank. The four corners of the load-bearing frame are equipped with a vertically arranged support leg 1, each The support legs and the load-bearing frame are hinged and reinforced by a tendon bar 5 (the reinforcement structure is: one end of the tendon bar 5 is hinged on the support leg, and the other end of the tendon bar 5 is fixed to the horizontal sliding bar 5-1 embedded in the beam of the load-bearing frame In the positioning opening 3-31 of the chute 3-3, after using the gland 6 to straddle the horizontal slide bar 5-1, the pin 6-2 is inserted into the pin hole 6-1 of the gland 6 and the corner of the load-bearing frame The pin holes 3-4 at the end make the tendons 5 to be fixed); the load-bearing frame is also provided with a lifting mechanism so that the load-bearing frame can vertically lift, and is provided with a translation mechanism that can adjust the horizontal displacement of the supporting legs.

The lifting mechanism is as follows: two vertically positioned inner cylinders 1-2 and outer cylinders 1-1 that are mutually nested and slidable form the support leg 1; the cylinder body 10 of the oil cylinder is installed on the support leg outer cylinder 1-1 The top of the piston rod 11 of the oil cylinder stretches down into the inner cavity of the inner cylinder 1-2 and is fixed with the bottom of the inner cylinder, and the outer cylinder wall of the outer cylinder is also equipped with an oil pipe joint 9 communicating with the cylinder block. After the oil delivery pipe of the configured oil pump (removable oil pump, omitted in the figure) is connected to the above-mentioned oil pipe joint, hydraulic oil can be input or extracted to realize relative sliding between the inner cylinder and the outer cylinder. Obviously, after setting the lifting mechanism, the loading and unloading frame has the overall lifting function.

The translation mechanism is: the upper end of each supporting leg (i.e. the outer cylinder 1-1) is fixed on a horizontally arranged sliding shaft 2, and the sliding shaft is inserted into a suitable sleeve 3-1 for sliding fit ; 4 sleeves are respectively fixed on the ends of the left and right ends of the load-bearing frame (that is, the ends at both ends of the length direction; usually, 2 sleeves at each end can be arranged coaxially). The purpose of setting up the translation mechanism is to expand the distance between the two supporting legs 1; because only when the opening distance of the two supporting legs is greater than the width of the vehicle, can the vehicle be driven in during loading and unloading, and only if the distance between the two supporting legs is greater than the width of the vehicle. Only when the width is smaller than the width of the vehicle can it go on the road; after the translation mechanism is set, the supporting legs have the function of telescopic adjustment in the width direction of the vehicle.
