The tank truck comprises a tank body 1, a ladder stand 2, a hinge base 3, a guardrail component 4 and a support piece 5.

Referring to fig. 1, a can body 1 is a hollow structure, and an inner space thereof is used for loading transportation articles.

Referring to fig. 4, in some embodiments, two opposite shoulders 11 are disposed on the left and right sides of the top of the can body 1, and the shoulders 11 extend along the front and rear direction of the can body 1. The two shoulders 11 form a receiving space 111 therebetween. It can be understood that the receiving space 111 is formed between the top of the can body 1 and the shoulder pad 11 when the top of the can body 1 is higher than the shoulder pad 11.

Referring to fig. 1, a ladder 2 is arranged on one side of a tank body 1, the upper end of the ladder 2 is connected to the top of the tank body 1, and a worker can climb to the top of the tank body 1 along the ladder 2.

The ladder 2 comprises two relatively parallel support bars 21 and a plurality of pedals 22. The lower section of the support rod 21 extends vertically, and the upper section of the support rod 21 is bent and fixedly connected to the top of the tank body 1. The pedals 22 extend along the transverse direction, a plurality of pedals 22 are arranged between the two support rods 21 at intervals up and down, and the pedals 22 are respectively and fixedly connected with the two support rods 21.

In some embodiments, a reinforcing rod 23 is arranged between the lower section of the ladder 2 and the side wall of the tank body 1, one end of the reinforcing rod 23 is connected to the lower section of the support rod 21, and the other end of the reinforcing rod 23 is connected to the side wall of the tank body 1. The connecting strength between the ladder stand 2 and the tank body 1 is increased through the reinforcing rods 23, so that the ladder stand 2 is not easy to shake when stressed.

Referring to fig. 4, and with reference to fig. 1 to 3, the hinge base 3 is disposed on the inner sidewall of the shoulder pad 11. It will be understood that the hinge base 3 can be disposed at other positions in the top receiving space 111 of the can body 1. The hinge block 3 is used to provide a mounting location for the guardrail assembly 4 and the support 5. The hinge base 3 is provided with a plurality of hinge bases which are arranged at intervals in a straight line.

In other embodiments, the hinge base 3 may be provided on the outside or top of the shoulder pad 11, and in this case, a recess or other receiving means may be provided on the top or outside of the shoulder pad 11 to receive the rail assembly 4 and the support member 5.

In some embodiments, the hinge base 3 is made of aluminum profile, which can reduce the weight of the whole vehicle.

Referring to fig. 1 to 4, the guardrail assembly 4 is disposed on the tank 1 and serves as a guardrail at the top of the tank 1 to prevent the operator from falling off the tank.

The guardrail assembly 4 comprises a cross bar 41 and a vertical bar 42. The cross bar 41 extends in the transverse direction and is disposed above the hinge base 3.

Referring to fig. 2 and 3, a plurality of vertical rods 42 are provided, and the plurality of vertical rods 42 are correspondingly provided on the hinge base 3. The lower end of the vertical rod 42 is hinged to the hinge base 3, and the upper end of the vertical rod 42 is hinged to the cross rod 41, so that the vertical rod 42 can rotate around the hinge base 3 by taking the hinge base 3 as a center, and drives the cross rod 41 to rise or fall. When an operator climbs to the top for operation, the vertical rod 42 can be rotated to the vertical state, the cross rod 41 is at the highest position at the moment, and the guardrail assembly 4 plays a role in protecting and preventing the operator from falling.

Specifically, the cross bar 41 gradually rises in the process of rotating from the upper end of the vertical rod 42 close to the tank 1 to the upper end of the vertical rod 42 away from the tank 1. When the vertical rod 42 rotates to be vertical or close to be vertical, the upper end of the vertical rod 42 is farthest away from the tank body 1, the cross rod 41 is at the highest position, and the vertical rod 42 is in the vertical state. In the process that the upper end of the vertical rod 42 is far away from the tank body 1 and rotates reversely to the upper end of the vertical rod 42 is close to the tank body 1, the cross rod 41 gradually descends. When the vertical rod 42 is rotated to the horizontal or nearly horizontal position, the upper end of the vertical rod 42 is closest to the tank body 1, the cross rod 41 is at the lowest position, and the vertical rod 42 is at the folded state.

It should be noted that, when the upper end of the vertical rod 42 is hinged to the cross rod 41, the top of the vertical rod 42 may be flush with the top of the cross rod 41, or the top of the vertical rod 42 may protrude from the top of the cross rod 41 as required.

The rotation plane of the vertical rod 42 rotating around the hinge base 3 is coincident with the installation plane, so that the swept volume of the vertical rod 42 in the rotation process is reduced, and the vertical rod 42 is prevented from colliding with an operator in the rotation process.

Still referring to fig. 4 in conjunction with fig. 2 and 3, in some embodiments, the hinge base 3 is disposed in the receiving space 111, and the guardrail assembly 4 disposed on the hinge base 3 is also disposed in the receiving space 111 when the vertical rod 42 is in the folded state. The height of the shoulder pad 11 is higher than the height of the rail 41 when the vertical rod 42 is folded, so that the rail 41 can be lowered to accommodate the rail 41 and the vertical rod 42 in the accommodating space 111 when the guardrail assembly 4 is not in use.

Referring to fig. 1 to 3, in some embodiments, the guardrail assembly 4 further includes a steel cable 43, a through hole is formed in the middle of the vertical rod 42, the steel cable 43 is inserted into the through hole of each vertical rod 42, and the two ends of the steel cable 43 are connected with each other. When the vertical rods 42 rotate to the vertical state, the vertical rods 42 at the two ends can tension the steel wire rope 43. The gap between the vertical rod 42 and the cross rod 41 is reduced by additionally arranging the steel wire rope 43, so that an operator is prevented from falling from the gap between the vertical rod 42 and the cross rod 41, and the guardrail assembly 4 is safer. And the number of the steel wire ropes 43 can be reasonably increased according to the requirement.

It can be understood that the steel wire rope 43 can also be inserted into the through holes of several middle vertical rods 42, and the head and tail ends of the steel wire rope 43 are respectively and fixedly connected with the vertical rods 42 at the two ends.
