FIG. 1 is a side view of a mobile cart for loading and unloading freight railway cars as provided herein;

fig. 2 is a front view of a mobile cart for loading and unloading freight railway cars as provided herein.

The attached drawings are marked as follows: 100-movable base, 110-travelling wheel, 111-directional wheel, 112-universal wheel, 200-step, 300-pedal and 400-supporting seat.

Detailed Description

The embodiment of the application provides the moving trolley for the freight train carriages, and solves the technical problems that in the related technology, a person enters the freight train carriages through the straight ladder, potential safety hazards exist, and the ladder is carried back and forth.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

the utility model provides a travelling car for freight transportation railway carriage from top to bottom, includes portable base, step and footboard, and portable base is equipped with the walking wheel, and the step is installed on portable base aslope, the top fixed connection of footboard one end and step, and the footboard other end stretches out portable base's vertical projection setting, and the one end that the step was kept away from to the footboard is used for setting up on freight transportation railway carriage.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Referring to fig. 1 and 2, the present embodiment discloses a mobile cart for loading and unloading freight train cars, which includes a mobile base 100, a step 200 and a pedal 300, wherein the mobile base 100 is provided with a traveling wheel 110, the step 200 is obliquely installed on the mobile base 100, one end of the pedal 300 is fixedly connected with the top end of the step 200, the other end of the pedal 300 extends out of the vertical projection of the mobile base 100, and one end of the pedal 300 away from the step 200 is used for being erected on the freight train cars.

When the freight train carriage needs to be entered, the operation moving trolley moves to a preset position along the flat ground beside the train rail, generally speaking, a cement ground is paved outside the gravel beside the train rail, the pedal 300 is carried on the freight train carriage, and the operator can enter the carriage through the steps 200 and the pedal 300 in sequence. Because the pedal 300 is arranged by extending out of the vertical projection of the movable base 100, the pedal 300 can stride over the gravel areas on two sides of the vehicle rail, thereby improving the potential safety hazard that the original vertical ladder is easy to slip when placed on the gravel at the bottom.

Through setting up portable base 100, be convenient for remove the position of step 200, the carriage of difference about the adaptation improves the great intensity of labour that originally need make a round trip to carry the ladder.

In addition, step 200 directly sets up on portable base 100 in this scheme, can strengthen the setting, has improved the defect of original high maintenance of ladder, and overall structure nature is better, maintains lowly, is favorable to ensureing the operating efficiency.

Optionally, the road wheels 110 are provided with a locking mechanism by which the position of the travelling carriage can be locked after it has been moved into position.

Alternatively, as shown in fig. 1 and 2, the road wheels 110 include a pair of directional wheels 111 and a pair of universal wheels 112, and the universal wheels 112 are disposed closer to the bottom end of the step 200 than the directional wheels 111. The adoption of the cooperation of the universal wheel 112 and the directional wheel 111 is not only beneficial to the adjustment at any time, but also can not overcome the defect of poor controllability of the moving direction existing in the full adoption of the universal wheel 112.

The locking mechanism is combined, and the mode of the self-locking universal wheel 112 can be directly adopted; the locking mechanism can also adopt a ground brake and the like.

The step 300 may be fixed relative to the step 200 or may be movably mounted, for example, in a folding manner at the top of the step 200. The foldable embodiment may be either a pull or a flip to ensure that the step 300 can be placed on the freight train car.

In order to improve the safety, the worker can enter and exit the freight train carriage along the steps 200 and the pedals 300 by installing a first guardrail on the steps 200, installing a second guardrail on the pedals 300, arranging anti-skid lines on the walking surface and the like, thereby improving the safety during walking.

Optionally, referring to fig. 1, the bottom end of the step 200 is fixedly mounted on the movable base 100. The mobile car further comprises a support base 400, the bottom end of the support base 400 is mounted on the movable base 100, and the top end of the support base 400 is fixedly connected with the step 200. Through setting up supporting seat 400, strengthen the relative stability of step 200, improve the security.

Optionally, the pedal 300 is further connected to the top end of the support base 400, so that the pedal 300, the top end of the step 200 and the top end of the support base 400 are connected, and the structural stability is further improved.
