Referring to fig. 1 to 6, there is shown an embodiment of a collapsible ladder stand for a tank according to the present invention, the tank having a frame 10, a tank body 20 and a pump chamber 30 provided in the frame 10, the tank body 20 and the pump chamber 30 being disposed adjacent to each other in a front-rear direction, the frame 10 being provided with the collapsible ladder stand 40.

The collapsible ladder 40 comprises: a ladder stand body 41 and a bracket 42, wherein the upper end of the ladder stand body 41 is hinged on the frame 10 of the tank; a bracket 42 is foldably provided between the lower end of the ladder body 41 and the frame 10 of the tank, the bracket 42 being for supporting the ladder body 41 in a pulled-out and deployed state. The support 42 is provided with a first support 421 hinged with the frame 10 of the tank and a second support 422 hinged with the lower end of the ladder climbing body 41, the first support 421 and the second support 422 are hinged, the second support 422 is provided with two second support plates 4221 arranged in parallel, an extending support part 4222 arranged along one end of the second support plate 4221 hinged with the first support 421 in an extending mode, and a limiting rod 4223 connected with the two extending support parts, and the limiting rod 4223 is located above the first support 421. A second hinge hole 4224 is formed between the second support plate 42221 and the extension support portion 4222, and the second support 422 is hinged to the first support 421 through the second hinge hole 4224.

Through the hinged arrangement of the ladder stand body 41 and the foldable hinged arrangement of the bracket 42, the operations of pulling out, unfolding and folding and retracting of the ladder stand 40 can be realized, the ladder stand 40 can be folded and retracted in the transportation process, the transportation requirement is met, and the occupied space is reduced when the ladder stand is not needed; when the climbing is needed, the lower end of the ladder stand 40 is pulled out, so that the climbing is simple, and the safety is improved. The extension support portion 4222 and the stopper rod 4223 are provided so that the stability of the bracket 42 can support the ladder body 41 so that the ladder body 41 is in a pulled-out state in a state where the ladder is in a deployed state. When the ladder stand 40 is folded and retracted, the limit rod 4223 is pulled to move upwards, so that the bracket 42 is folded, the lower end of the ladder stand body 41 moves inwards, and the ladder stand body 41 rotates around the upper end.

Referring to fig. 5, the first bracket 421 has two first bracket plates 4211 arranged in parallel, the first bracket plates 4211 have first bracket plates 42111 hinge-jointed with the frame 10 of the tank, first extension parts 42112 extending along the end of the first bracket plate 42111 in a bending manner, and the first extension parts 42112 hinge-jointed with the second bracket 422. In the unfolded state of the ladder 40, the first extension 42112 is bent outwardly and upwardly along the end of the first support plate 42111. The included angle between the first support plate 42111 and the first extension portion 42112 is 160-175 degrees. By providing the first support plate 4211 as a bent structure, it is advantageous to form a support for the second support 422, and to increase structural strength.

As shown in fig. 6, the second bracket plate 4221 includes a second bracket plate 42211 hinged to the lower end of the ladder body 41, and a second extension portion 42212 bent and extended along the end of the second bracket plate 42211, and the extension support portion 4222 is connected to the second extension portion 42212. In the unfolded state of the support 422, the second extension 42212 is bent inward and downward along the end of the second support plate 42211. The extension support 4222 extends in the same direction as the second extension 42212. The included angle between the second bracket plate 42211 and the second extending part 42212 is 150-170 degrees. The second support plate 4221 is of a bent structure, so that the first support 421 can be lapped and limited, and the limiting rod 4223 is located above the first extension portion 42112.

Referring to fig. 2, the tank is provided with an operating platform 31, the ladder stand 40 further comprises a pedal 46 overlapping the operating platform 31, and the outer end of the pedal 46 is connected with the ladder stand body 41. By arranging the pedal 46, after the ladder stand 40 is pulled out in a rotating manner, the pedal 46 is lapped on the operating platform 31, so that a gap between the ladder stand body 41 and the operating platform 31 is avoided, and the safety is improved.

In order to meet the transportation requirement, the ladder 40 cannot protrude out of the frame 10 after being folded, a container 32 for accommodating the folded ladder 40 is provided on the tank, the top of the pump chamber 30 is an operation platform 31, and the left and right side portions of the pump chamber 30 and the frame 10 are surrounded to form the container 32.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
