Description

Technical Field

[0001] The invention relates to the technical field of railway loading, and in particular to a self-propelled intelligent loading machine. Background Art

[0002] A loader is a loader used to continuously load materials or articles into a carriage. In the prior art, for example, the utility model patent with application number 201820628500.3 and the utility model patent with application number 201120289129.0 are both provided with a receiving trough on the loader, and a conveyor is provided between the receiving trough and the carriage to be loaded. When loading, the unloading truck parked on the unloading yard dumps the materials into the receiving trough, and the goods in the receiving trough are transported to the carriage to be loaded under the action of the conveyor, thereby completing the loading process. The following problems exist in this loader: a tallying device needs to be set up in the compartment to be loaded to prevent the materials loaded into the compartment from piling up in one place; in addition, when it is necessary to load cargo into multiple compartments to be loaded at different positions, the loader and the unloading truck need to be moved to the loading position of the new compartment to be loaded, and the positional relationship between the unloading truck and the loader needs to be readjusted so that the compartment of the unloading truck faces the material receiving trough, and then a new round of loading work can be started. When this loading method is used to load cargo into compartments to be loaded at different positions, the operation is rather cumbersome.

[0003] In summary, the prior art lacks a self-propelled intelligent loader that does not require a tallying device to be set up in the loading compartment and does not require repeated adjustment of the positional relationship between the unloading truck and the loader when loading the loading compartments at different positions, and is relatively simple to operate. Summary of the invention

[0004] The object of the present invention is to provide a self-propelled intelligent loader in response to the defects and shortcomings in the prior art. By providing a vehicle carrying part that can carry an unloading truck, during the loading process, the self-propelled intelligent loader drives the unloading truck to move synchronously, so that the goods can be loaded into different positions in the truck compartment to be loaded, eliminating the need to set up a sorting device in the truck compartment to be loaded, and the loader and the unloading truck can be moved synchronously from one truck compartment to be loaded to another. Compared with the prior art method that requires moving the unloading truck and the loader separately and then readjusting the positional relationship between the unloading truck and the loader, the present invention has the unloading truck and the self-propelled intelligent loader moving synchronously, so their relative positions will not change, eliminating the need for repeated adjustment of the positional relationship between the unloading truck and the self-propelled intelligent loader, thereby improving the loading efficiency.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The object of the present invention is to provide a self-propelled intelligent loader in response to the defects and shortcomings in the prior art. By providing a vehicle carrying part that can carry an unloading truck, during the loading process, the self-propelled intelligent loader drives the unloading truck to move synchronously, so that the goods can be loaded into different positions in the truck compartment to be loaded, eliminating the need to set up a sorting device in the truck compartment to be loaded, and the loader and the unloading truck can be moved synchronously from one truck compartment to be loaded to another. Compared with the prior art method that requires moving the unloading truck and the loader separately and then readjusting the positional relationship between the unloading truck and the loader, the present invention has the unloading truck and the self-propelled intelligent loader moving synchronously, so their relative positions will not change, eliminating the need for repeated adjustment of the positional relationship between the unloading truck and the self-propelled intelligent loader, thereby improving the loading efficiency.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

When loading, the walking part 2 moves the self-propelled intelligent loader to a position parallel to the truck compartment to be loaded, the unloading truck drives and parks on the vehicle carrying part 1, the unloading port of the unloading truck is opened, and the cargo is loaded. The goods fall to the conveying part 3 through the unloading port, and are transported to the interior of the compartment to be loaded by the conveying part 3. The walking speed of the walking part 2 is adjusted to match the loading speed, so that when the walking part 2 moves from the front of the compartment to be loaded to the rear of the compartment to be loaded, the goods in the compartment to be loaded are just filled and the loading is completed; by setting the extension direction of the conveying part 3 to be perpendicular to the extension direction of the vehicle carrying part 1, it can be avoided that the movement direction of the goods is inconsistent with the conveying direction of the conveying part 3, resulting in the goods falling from the conveying part 3 during the conveying process, resulting in loading failure.

[0031] The conveying part 3 includes a horizontal section 31 fixedly connected to the vehicle bearing part 1 and a variable amplitude section 32 rotatably connected to the horizontal section 31. The horizontal section 31 is provided with two bridge plates 311 that can be rotatably opened to form a receiving trough 33. The first rotating shafts 312 of the two bridge plates 311 are respectively arranged on both sides of the horizontal section 31 along the forward direction of the unloading truck, so that after the bridge plates 311 are rotated and opened around the first rotating shafts 312, a receiving trough 33 with an upper end opening can be formed on the horizontal section 31, and the side openings of the receiving trough 33 are consistent with the conveying direction of the horizontal section 31, so that materials falling into the receiving trough 33 can be transported to the loading compartment along the horizontal section 31 and the variable amplitude section 32; the bridge plate 311 is a straight plate, so the receiving trough 33 has at least one side opening. When the two sides of the receiving trough 33 have a side opening respectively, the goods accumulated in the receiving trough 33 may fall from the side opening on the side away from the forward direction of the goods. To avoid this problem, the present invention sets a first baffle 313 on the side of the receiving trough 33 away from the direction of the goods moving forward, so that the receiving trough 33 only retains the side opening consistent with the direction of the goods moving forward, thereby preventing the goods from falling and improving the transportation efficiency; a first lug 314 is provided on the frame of the horizontal section 31, and the other end of the first rotating shaft 312 is rotatably connected to the first lug 314, and a first telescopic oil cylinder 315 is provided at the lower end of the bridge plate 311, away from the hinge point of the first rotating shaft 312 and the first lug 314.

Preferably, the first accommodating cavity 14 is slightly larger than the limiting protrusion 12, so that the limiting protrusion 12 can rotate smoothly. When the limiting protrusion 12 rotates out of the first accommodating cavity 14, the top surface of the limiting protrusion 12 is higher than the surface of the speed bump 13 by a certain distance, so that the limiting protrusion 12 can limit the position of the unloading truck. Preferably, the top surface of the limiting protrusion 12 is higher than the surface of the speed bump 13 by 10 cm to 15 cm. When the limiting protrusion 12 is located in the first accommodating cavity 14, the side surface of the limiting protrusion 12 is flush with the surface of the speed bump 13, so that the unloading truck can smoothly leave the chassis 11; The lower part of the protrusion 12 is provided with a first connecting block 15 fixed in the first accommodating cavity 14, one end of the limiting protrusion 12 is provided with a second lug 16, one end of the first connecting block 15 is provided with a third lug 17, and a second telescopic oil cylinder 18 is rotatably provided between the second lug 16 and the third lug 17.
