A transport trolley for going up, lower step

Technical Field

The application relates to the technical field of transport means, in particular to a transport cart for an upper step and a lower step.

Background

In a production work area, a high-level area or a low-level area is always arranged for production or safety requirements, and the high-level area or the low-level area is connected with a flat-level area through an upper step and a lower step. In daily production, heavy object carrying work between different areas often exists, for example, replacement of a main air conditioner, maintenance and replacement of a circulating pump and a motor, and the like.

When carrying heavy objects, a mechanical gripper can be adopted for a factory building with a large height. However, for a factory building with a small height, only manual work or a flat cart can be used for carrying heavy objects, and manual carrying is time-consuming and labor-consuming. The flat-plate trolley is convenient and easy to carry in a plane road section, needs a plurality of people to assist in operation in the processes of ascending and descending steps, wastes time and labor, and is easy to cause the phenomenon of side turning of the trolley in the retreating process, thereby causing damage to heavy objects or injury to personnel.

Therefore, a transport cart for ascending and descending steps is needed.

FIG. 1 is a schematic structural view of a transport cart for upper and lower steps according to the present application;

fig. 2 is a schematic structural view of a wheel assembly according to the present application.

The designations in fig. 1-2 are respectively expressed as:

the method comprises the following steps of 1-a trolley body, 11-a base support, 12-a side back support, 13-a gear support, 14-a handle, 15-a connecting cross rod, 2-a rotating rod, 3-a wheel assembly, 31-a wheel fixing rod, 32-a roller and 4-a limiting rod.

Detailed Description

Fig. 1 is a schematic structural diagram of the transportation cart for upper and lower steps, and as shown in fig. 1, the transportation cart for upper and lower steps of the present application includes a cart body 1, and the cart body 1 is used for bearing a heavy object to be transported. In this application, shallow body 1 specifically includes base support 11 and side back of the body support 12, during the use, treats that the transportation heavy object is placed on base support 11, treats that a side of transporting the heavy object leans on side back of the body support 12 closely, and in the transportation, side back of the body support 12 can prevent to treat that the transportation goods drops. For the fastness of ensureing shallow body 1, in this application, base support 11 and side back of the body support 12 are integrated into one piece, have strengthened shallow body 1's structural strength to the life of extension transportation shallow, simultaneously, strengthened the bearing capacity of transportation shallow to the goods.

In order to facilitate the loading and transporting of a plurality of small-sized heavy objects with a large number of corners, in the embodiment, the transport cart further comprises a transport hopper, when in use, the transport hopper is fixed on the cart body 1, and then the heavy objects to be transported are placed in the transport hopper.

To further limit the displacement or falling of the goods to be transported, a stop bracket 13 is provided on the side of the base bracket 11 remote from the side back bracket 12 in this example.

In order to facilitate the operation of the transportation personnel, in this embodiment, a handle 14 is disposed on one side of the side back support 12 away from the base support 11, and when the side back support is used, the transportation personnel can hold the handle 14 by hand to realize the operation control during the transportation of the heavy objects.

The base support 11 with the horizontal pole of side back of the body support 12 handing-over is for connecting horizontal pole 15, and the both ends of connecting horizontal pole 15 are equipped with respectively and connect a wheel subassembly 3 through dwang 2. Fig. 2 is a schematic structural diagram of the wheel assembly of the present application, and as shown in fig. 2, the wheel assembly 3 includes three wheel fixing rods 31, one end of each wheel fixing rod 31 is fixed at the same point, the other end of each wheel fixing rod 31 is connected with a roller 32, and the included angle between the three wheel fixing rods 31 is 120 °.

In the vehicle assembly on each side, two of the three rollers are simultaneously grounded and brought into close contact with the ground during the operation on a flat road, a force directed toward the ground is applied to the handle to release the base bracket from contact with the ground, and then a force directed in a direction parallel to the ground is applied to the handle, under which force the transport cart is moved. When the trolley runs on an ascending step, a pulling force upwards pulling the step is applied to the transport trolley through the handle, under the action of the pulling force, the wheel assembly rotates by taking the roller which lands and is close to the previous step as an axis, the roller which does not land rotates to the previous step in the rotating process, then the roller which rotates to the previous step continues to rotate by taking the roller which rotates to the previous step as the axis, the roller which just lands on the next step and is far away from the previous step rotates until the roller rotates to the step of the previous step, and the steps are repeated, and finally the heavy object can be transported to the uppermost end of the step. When the wheel assembly touches a descending step, the wheel assembly rotates by taking one of the landing rollers as an axis, so that the roller which does not land rotates to the next step, and the steps are repeated, and finally the heavy object can be conveyed to the lowest end of the step.

In order to prevent the wheel assembly 3 from separating from the rotating rod 2 in the rotating process, in the embodiment, a limiting rod 4 is arranged at one end of the rotating rod 2, which is far away from the connecting cross rod 15. The stop 4 is effective now to offset the wheel assembly 3 in the direction of the turning rod 2 along the long axis of the beam.

The above-described embodiments of the present application do not limit the scope of the present application.
