Abstract

A boom arm locking system for backhoe loaders comprises a pivoting locking plate 17, which, when locking pin 22 is released, pivots to latch with projections on the boom 10 in order to prevent vertical motion and engages with projections 35 on the vehicle frame to prevent rotational movement of the boom arm. The arm may also be locked in a left-hand or right-hand configuration (figs 7 & 8).

Description

DESCRIPTION
A LOCKING SYSTEM
Technical Field
This invention relates to a locking system for the backhoe loaders, one of the most commonly used heavy equipment of the present day, said locking system providing safe drive in the traffic by preventing the involuntary motion of the turning joint and the boom mechanisms available at the rear part of the vehicle.
Prior Art
In the document no. US 5064339 according to the state of the art, an invention is disclosed, which is about the ability to lock the boom by means of a T-shaped latch mounted on the rotating frame.
Moreover, in the application document no. US 5967737 according to the state of the art, a hook type lock mechanism for the boom is the subject matter of the invention.
The utility model no. TR 2011/06742, which is another application according to the state of the art, is about the use of a lock pin-containing mechanism in the heavy equipment.

The backhoe loader type of heavy equipment is comprised by several main sections. These sections are the following: -The chassis (7) bearing all the parts, front wheel and axle (4), rear wheel and axle (5), loader (3), loader bucket (1), cabin (2): engine hood (6); -the table (8) forming the backhoe assembly and providing the connection with the backhoe section, the backhoe bucket (15) serving to dig ditches, the cylinder (14) actuating the backhoe bucket (15), the stick (12) enabling the backhoe bucket (15) to move; -the boom (10) moving the stick (12) and the bucket (15) in the downward and upward directions, the turning joint (9) enabling the boom (10) to move through about 180° to the right and left and the turning cylinder (11) actuating the turning joint (9).
In order to perform the excavation operation with the backhoe loader equipment, a turning joint (9) is mounted to the table (8) at the pear part of the machine, said turning joint (9) enabling the boom (10) to move in the upward-downward and leftward-rightward directions.
The boom (10)15 intended to move in the upward and downward directions by way of being mounted to the turning joint (9) with a boom pin (30). The upward-downward movement of the boom (10) is provided by means of a cylinder. The boom cylinder (38) connects to the turning joint (9) via the cylinder pin (33). When the cylinder (38) opens, the boom (10) S moves downwards, and when the cylinder (38) closes, the boom (10) moves upwards.
The turning joint (9) connects via the connection points to the table (8) at the rear part of the machine, via the lower pin 1 (28) and the upper pin 1 (32). The rightward and leftward movement of the turning joint (9) is provided by means of the turning cylinders (11) that are present at a quantity of 2. The turning cylinders (11) connect via the lower pin 2 (29) to the turning joint (9). The turning cylinders (11) perform movement in a synchronous manner to enable the turning joint (9) and the boom (10) mounted on the joint to move towards the right and the left.
The piece preventing the horizontal motion (35) available on the table (8) is used for preventing the rightward-leftward movement of the turning joint (9), while the piece preventing the vertical motion (34) available on the boom (10) is used for preventing the upward-downward movement of the boom (10).
In order to lock the boom (10) and the turning joint (9) with the locking system according to the invention, the arm (24) mounted on the pin (22) is pulled, thereby enabling the pin (22) fitted into the housing (26) on the turning joint (9) to come out of the housing. When the arm (24) is pulled, the locking plate (17) moves in the direction of the center of gravity, under the influence of the gravitation. Under the influence of this movement, the locking point 1 (36) on the locking plate (17) is seated on the piece preventing the vertical motion (34) available on the boom (10) and the locking point 2 (37) is seated on the piece preventing the horizontal motion (35) available on the table (8). The locking system according to the invention enables in this manner the boom (10) and the turning joint (9) to be locked.
In order to unlock the boom (10) and the turning joint (9) with the locking system according to the invention, the lock pin (22) pushes and compresses the spring (19) within the mechanism when the locking plate (17) drops down, and the lock pin (22) at the other end bears against the lock housing (16) on the turning joint (9). In this way, a force is generated on the spring (19). The locking plate (17) is lifted up by hand and when the plate (17) attains the parallel position, the pin (22) fits into the housing (16) owing to the force accumulated on the spring (19) and thus the lock is brought into the open position. The locking plate (17) thus reaches the parallel position. In this manner, the turning joint (9) and the boom (10) are able to move freely.
Another characteristic of the locking system according to the invention is that the boom (10) and the turning joint (9) feature the ability to be locked at an angle of both 00 and 1800.
