Definitions
- the present invention relates to a hydraulic locking system a tool on the tool carrier frame of a front loader, the lifting of the stretcher is controlled by a hydraulic cylinder, called lifting.
- the invention aims to solve these problems.
- the system which is the subject of the present invention comprises at least minus a lock controlled by another hydraulic cylinder - called a locking cylinder - which is supplied with hydraulic fluid, via a solenoid valve, from the pressure chamber of the lifting cylinder, so that unlocking the tool is only possible if the hydraulic pressure in this pressure chamber exceeds a threshold value predetermined.
- said solenoid valve is electrically controlled by means of a push button embedded in the wall of a control handle, this which makes it difficult to access.
- the system includes a stretcher tilt sensor electrically connected to said solenoid valve so as to prohibit the control of the unlocking cylinder in the event of tilting excessive.
- This arrangement eliminates the risk of the tool stalling when it found in high position.
- the reference T denotes an agricultural tractor equipped with a front loader C comprising, in the usual manner, an articulated stretcher B provided at its front end with a tool-carrying frame 2.
- the loader has a pair of lifting cylinders 1 (only one of which is visible in the front view corresponding to the diagram), which make it possible to pivot the stretcher B around its axis of articulation X to cause lifting or lowering of the tool carried by the frame 2.
- the tool is not shown in Figure 1. In the following figures, it is a bucket, designated O.
- It also includes a VB tipping cylinder allowing the tool to pivot relative to the stretcher.
- the lifting cylinder 1 is double-acting. It comprises a piston 10 secured to the frame of the loader, and a cylinder 11 secured to the stretcher B.
- the tractor T is equipped with low and high pressure hydraulic sources, respectively BP (atmospheric pressure) and HP (pressure of the order of 15.10 7 to 2.10 7 Pa).
- BP atmospheric pressure
- HP pressure of the order of 15.10 7 to 2.10 7 Pa.
- Line 8 corresponds to the supply of high pressure liquid, and line 9 when returning to the tank (low pressure line).
- the conduits 8, 9 are connected, via a three-position control valve 5, on the one hand to the small chamber 101 (side of the piston rod 10) of the jack 1, on the other hand to its large chamber 100.
- This will be conventionally designated in the following description and in the claims "pressure chamber”. It is, in fact, the bringing of the liquid under pressure into this chamber 100 which causes the extension of the jack and the lifting of the tool.
- connections between the distributor 5 and the chambers 100 and 101 are referenced respectively 80-80 'and 90.
- the tool holder frame 2 which is shown even from the side on the right of the figures, comprises in the upper part, two semi-cylindrical housings 21 in which can engage appropriate pins provided on the tool.
- a pair of latches in the form of horizontal, coaxial rods 32, 33. They are carried by a jack hydraulic 3, arranged transversely, the cylinder of which is designated 31 and the piston 30.
- One 32 of the locking rods is fixed in the extension of the piston rod 30, and the other 33 on the back of the cylinder 31.
- a pair of helical springs 20 tends constantly pushing the locks 32, 33 outwards, which corresponds to the extension of the cylinder 3, in a locked position. In this position, the free end portions locks engage in appropriate receiving openings provided on the tool.
- high pressure liquid is brought into the small chamber 301 of the cylinder, while the large chamber is connected to the reservoir R (low pressure), which causes the retraction of the cylinder, and the retracting locks.
- the value of the high pressure is sufficient to overcome the force of the springs 20.
- the jack 3 is controlled by a control solenoid valve 6, with two positions.
- the chamber 301 communicates with low pressure via conduits 81, 83. In the position shown in Figures 2 and 3, it communicates with the above-mentioned line 80 '(connected to the chamber pressure cylinder 100).
- the large chamber 300 of the jack 3 is permanently connected, by a conduit 82, to the reservoir. It is therefore always subjected to low pressure.
- the solenoid valve 6 is controlled by an electric switch 700, itself actuated by a push button 70.
- the push button 70 is embedded in the handle 7.
- its support face of the finger is located at a level lower than the surface of the handle, which makes access difficult; the risk of it being pressed inadvertently is therefore practically zero.
- an inclination sensor 4 of the known type. It is for example a mercury level switch, connected to the supply circuit of the solenoid valve 6. It is adjusted so that the circuit is closed when the height H 1 of the tool relative to the ground S is less than a determined height H 0 (situation illustrated in Figure 3), and open when this height H 2 is greater than H 0 ( Figure 4).
- the value of the threshold height H 0 is preferably of the order of 1.50 m, less than the average height of a person.
- the switch 700 is in the open state, which is its natural state.
- the solenoid valve 6 is in the state of FIG. 1, so that the two chambers 300, 301 of the jack 3 are connected to the tank R and are at low pressure.
- the tool O is kept locked on the frame 2 by means of the two locks 32, 33 which are subjected to the sole action of the springs 20.
- the cylinder is therefore requested in extension, in the locking direction, this which eliminates the risk of accidental unlocking.
- the pressure in the chamber 100 of the lifting cylinder 1 is therefore low.
- the chamber 301 of the unlocking cylinder 3 is thus placed in communication, via conduits 81 and 80 ', with chamber 100.
- the latter being low insufficient pressure to overcome the springs 20, the cylinder 3 remains in extension, and the unlocking cannot take place.
- the tilt sensor 4 comes into action, keeping the supply circuit of the solenoid valve 6 open. It therefore remains in its natural state, in which the chamber 301 of the unlocking cylinder is subjected to low pressure. Unlocking is impossible. Thus, there is no risk of accident which could result from the presence of a person under the tool O at the time of its stall.

- il comporte un système élastique qui sollicite les verrous dans le sens du verrouillage, à l'encontre de la pression hydraulique du vérin de déverrouillage;
- le vérin est à double-effet et la pression différentielle dans ses deux chambres tend à le maintenir en extension, dans le sens du verrouillage.
- la figure 1 est un schéma général représentatif de l'ensemble du système, appliqué à un chargeur monté sur un tracteur agricole, outil enlevé ;
- les figures 2, 3 et 4 sont des schémas similaires à la figure 1, avec l'outil en place, qui montrent des positions différentes du brancard, respectivement en position basse (de repos) (figure 2), en position légèrement relevée (figure 3), et en position haute (figure 4).
