Abstract

The utility model relates to hoisting and transport machinery, in particular for the purpose of loading or unloading palletized cargo to / from a container or a car. The loading and unloading trolley includes a means for lifting cargo, with a hydraulic mechanism, while the means for lifting cargo is made in the form of a lifting frame 2, mounted on a supporting frame 1 forming a two-frame structure, the lifting and supporting frames are made of profile elements, while between the frames have a lifting mechanism, consisting of a lifting roller 6 and a lifting wedge 5, and a running roller 7 is located inside the support frame. A loading and unloading trolley provides lifting and moving any load placed on and standard pallets. (unloading of a 20 foot container with a palletized load in one technological cycle, 40 foot container in two technological cycles)

Description

The utility model relates to hoisting and transport machinery, in particular for the purpose of loading or unloading palletized cargo to / from a container (car).

Known loading and unloading system (www.joloda.com) for loading / unloading bulky goods to / from containers. The system is a folding rail installed inside the container on an inclined ramp under the load. The movement of the cargo is carried out by means of hydraulic trolleys moving on rails.

The disadvantages of the system are

the use of a special (non-standard) pallet for cargo unfastening,

manual movement of cargo during filling / unloading.

The system allows you to load the entire container at the same time (cargo up to 12 meters long and weighing up to 24.5 tons), using an inclined ramp and special lifting jacks to install the tare container inclinedly.

Known trolley for transporting goods laid on a pallet (AC SU No. 1194731 from 11/30/1985). The trolley contains a platform with rollers and a device for fixing the pallet on the rollers.

The disadvantage of this trolley is that the trolley allows filling / unloading of the container only if the trolley itself is transported in the container. (return filling equipment: the trolley itself is used as a pallet on which the cargo is placed).

Known manual lifting trolley (AC SU No. 489668 from 10/30/1975) containing mounted forks mounted on retractable rollers connected to the upper end of the piston rod of the hydraulic power cylinder. The truck forks are brought under the base of the pallet with the load and by moving the handle through the hydraulic mechanism raise the pallet with the load. Next, the trolley is moved to any desired location.

A disadvantage of the known construction is the inability to move long and large-tonnage loads (for example, lumber up to 6.3 m long).

The objective of the utility model is the development of a loading and unloading trolley that provides the lifting and moving of long and large cargo for

filling / unloading of large tonnage containers, while minimizing manual labor, using a loader with a lifting capacity of up to 4.5 tons without additional devices.

The technical result consists in the creation of a universal loading and unloading trolley that provides lifting and moving any cargo placed on standard pallets. (unloading of a 20 foot container with a palletized load in one technological cycle, 40 foot container in two technological cycles)

The utility model problem is solved as follows.

The loading and unloading trolley is made in the form of a two-frame structure. One of the frames is the support, and the other is lifting. Loading and unloading trolley, includes a means for lifting cargo with a hydraulic mechanism. Means for lifting cargo is made in the form of a lifting frame. The lifting frame is mounted on a support frame. The supporting and lifting frames are made of profile elements, while a lifting mechanism consisting of a lifting roller and a lifting wedge is installed between the frames, and a running roller is located inside the supporting frame.

Figure 1 presents a General view of the loading and unloading trolley, where 1 is the supporting frame, consisting of profiled elements 2 - lifting frame, consisting of profiled elements 3 - hydraulic station, 4 - hydraulic cylinder.

Figure 2 presents a part of a side view, where 1 is a support frame consisting of profiled elements 2 is a lifting frame consisting of profiled elements 5 is a lifting wedge, 6 is a lifting roller, 7 is a running roller.

The lifting and transportation of the loading and unloading trolley is as follows, (one technological cycle)

The lifting trolley in the initial state moves under the load installed on pallets. (at the same time, 10 pallets with a total weight of up to 18 tons, or a load up to 6.3 meters long with the same weight can be lifted) To carry out the lifting of the load, pressurize the hydraulic cylinder 4 with the help of a hydraulic station 3 located on the supporting frame 1. Stock the hydraulic cylinder moves the lifting frame 2, which, moving along the lifting rollers 6 along the lifting wedges 5, lifts the load located on the lifting frame 2. After lifting the load, the trolley moves to / from the container with the help of a loader.

After depressurizing the hydraulic cylinder 4, the lifting frame 2 is lowered under its own weight or the weight of the cargo, and the trolley returns to its original state.

Claims (1)
