For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0058] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] Example:

[0060] like Figure 1 As shown, an embodiment of the present application discloses a movable guardrail on a tank top, which is used to control the rise and fall of the guardrail by climbing a ladder when going up and down the tank top. Its specific structure includes: a front ladder 1, a movable guardrail assembly 2 and a linkage assembly 3.

[0061] The front ladder 1 is installed vertically at the front end of the tank body; in order to avoid the junction box, the front ladder 1 is placed in the middle. In order to prevent the front ladder 1 from shaking greatly when people step on it and to prevent fatigue damage from occurring quickly during the operation of the tank truck, multiple reinforcing ribs are used to reinforce the lower part connected to the tank body to ensure that the front ladder 1 has the minimum shaking amplitude.

[0062] The movable guardrail assembly 2 is installed horizontally on the top of the tank body; it can be raised and lowered for safety protection.

[0063] The linkage assembly 3 is used to drive the movable guardrail assembly 2 to rise and fall, and includes:

[0064] Two limiting plates 31 are vertically installed on both sides of the front ladder 1 , and are preferably in the shape of rectangular plates with a through hole in the middle for supporting the U-shaped rod 32 .

[0065] The middle portion of the U-shaped rod 32 passes through the two limiting plates 31 and can rotate freely; the length of the middle portion of the U-shaped rod 32 is greater than the width of the front ladder 1 .

[0066] Two connecting plates 33 are respectively installed on both sides of the front end of the movable guardrail assembly 2. The connecting plates 33 are triangular in structure and are used to improve the structural strength. In order to save materials, a plurality of circular holes are opened thereon.

[0067] One end of the two push-pull rods 34 is respectively hinged to the ends of both sides of the U-shaped rod 32, and the other end is respectively hinged to a connecting plate 33, forming a bending shape to improve the compactness of the structure.

[0068] The push rod 35 is installed on the middle part of the U-shaped rod 32; the push rod 35 is U-shaped, and the width matches the width of the front ladder 1 to avoid interfering with the climbing of the operator.

[0069] In the above technical solution, the operator climbs to the top of the tank body through the front ladder 1, and drives the linkage assembly 3 before climbing, specifically flipping the push rod 35 downward, thereby driving the U-shaped rod 32 to rotate in the two limit plates 31, thereby pulling the two push-pull rods 34 to move, and the two push-pull rods 34 respectively pull a connecting plate 33, and the two connecting plates 33 pull the movable guardrail assembly 2 to work, so that it changes from a falling state to a raised state; at this time, the operator can be protected by the guardrail after climbing to the top of the tank body through the front ladder 1, and when the operator comes down from the top of the tank, flip the push rod 35 upward, so that the movable guardrail assembly 2 can be driven to change from a raised state to a falling state.

[0070] The utility model installs a linkage assembly 3 on the front ladder 1, so that it can form a linkage with the movable guardrail assembly 2, thereby realizing the automatic raising and lowering of the movable guardrail assembly 2, eliminating the need for the use of cumbersome pneumatic devices that require installation and manufacturing, simplifying the air path of the entire vehicle, reducing the difficulty of manufacturing the guardrail part, reducing the number of air control valves of the entire vehicle, reducing the cost of the entire vehicle, and being very easy to operate, which can effectively protect the workers in the tank top tank.

[0090] The top of the front ladder 1 is installed on one side of the support plate 211 close to the linkage assembly 3, and is connected by inserting a plurality of bolts on two concave plate members.

[0091] By setting the supporting structure 21 as above, the two guardrail components 22 can be stably supported, and a corridor can be formed for workers to walk. The structure is simple and stable, and it is easy to produce and assemble, and has a good use effect.
