acting hydraulic cylinder is actuated, whereby the arms of the articulated lever bit the corresponding inboard sections of the Teretärkungsarms and the pipeline are connected. By choosing a connection rod with suitable GtOMetry, which is to be explained further below in connection with the drawings an arrangement can be provided in which, when the reach adjusting devices are fixed in a given position, the beak can be moved up and down so that it runs along a substantially vertical line.

The gate direction also contains height adjustment devices by which the scissor linkage and the beak connected with it are swiveled around the axis of the first horizontal swivel joint, and it is also one Yerschwenkrorrichtung gate seen to move the gate direction in a horizontal plane around the axis of the vertical swivel joint BU

Although all three components are preferably from double-acting hydraulic cylinders exist, the τοη be carried on a platform that is firmly attached to the 90 ° knee of the feed line, it is still light possible, both the Heichweiteinstellbewegung, the Höheneinstellbewegung and the Terschwenkbewegung τοη hand To do this, and to act on the upright supply line that carries the assembly Keeping the moment as small as possible is the weight of the scissor arms and the tendon at the pivot point around the first horizontal swivel joint constantly rolling through Counterweight balanced · Furthermore, a second counterweight rerwandt along the line arm is arranged so that it takes the weight of the tendon and the

2098U / 0899

outer line arm section balances weight when this latter arm section is in lezug moved to the inner line section.

The device also includes a retractor with a spring biased bumper that protrudes from the lower end of the beak and which, when moved into the beak, actuates a switch which stops the downward movement of the beak and which causes the beak to go back a few inches is moved upwards.

The designation of the swivel joints as "horizontal" or "vertical ^11" refers to the direction of their longitudinal axes about which the moving parts can rotate.

The invention further consists in the combination, construction and arrangement of the parts as they emerge from the accompanying drawing, and although only a preferred embodiment of the invention is shown in the drawing, the invention is by no means limited to this embodiment only, but in the context of the invention Ψ amendments and changed Konstruktlonseinzelheiten are readily rather possible. In the following, the invention is to be explained in more detail with reference to an exemplary embodiment shown in the drawing. In the drawing show:

? ig. 3, 4 and 5 general schematic representations, the show essentially straight vertical movement made by the beak) when the beak carrying device progressing in a position determined in relation to the range from a fully raised to a middle and then to a fully lowered position is moved;

Pig. 6 is a schematic representation of part of FIG Control circuit for the tank truck loading device.

In Pig. 1, a downwardly directed upright riser 10 is shown attached in a fixed position a support frame (not shown) is supported, which is firmly anchored in the ground. This conduit is used as a line through which the beak 12 through the inner and outer sections 15 and 16, respectively articulated line arm, which is generally designated 17, is supplied to be loaded liquid. The latter Arm is placed over an articulated reinforcement arm, which is designated generally by 18 and which has an inner section 19 and an outer section 20 owns. The corresponding sections of each arm have the same length. These arms together form a scissor arrangement which is arranged in a vertical plane and which carries the downwardly hanging beak 12.

The riser 10 has a horizontal flange 25 on which a vertical swivel joint 26 is attached, in which rotatably a 90 ° knee 27 is attached to the supply line. lin first horizontal swivel joint 28 is with the IMe 27 connected, and the line arm 17 iet in this swivel joint

Mounted pivotably via a 90 ° -Khie 29. As can be seen in greater detail from Pig'2, the arm encompasses 17 next to the knee 29 a straight section 30, a 90 ° knee 31 »a second horizontal swivel joint 33, a 90 ° knee 35, a straight line section 36, a 90 ° elbow 37 and a third horizontal swivel joint 38, all three horizontal swivel joints having axes parallel to one another and lie in the same vertical plane. The loud 29, 30 and 31 together form the inner line section (which is denoted by 15 in FIG. 1) of the arm 17, while the components 35 »36 and 37 form the line section located on the outside, which is denoted by 16. The inner section 15 thus has the shape of a TJ, while the outer section 16, which via the swivel joint 33 communicating with the inboard portion is in the shape of an inverted U having a base slightly offset from the inboard arm portion. This base part forms an attachment point for the outer end of the arm 18 in a pivot joint 40, whereby the arm 18 in connection with the pivot joint 41, on which the inside find this arm attached to the knee 27 on the axis of the horizontal pivot joint 28 is aligned in a parallel plane with the straight sections of the arm 17.

The tendon 12 is provided at its upper end with a knee 45, since it is rotatably mounted in the swivel joint 38, so that the beak can thus always freely assume a vertical position. On an upper portion of the beak an annular bracket 46 is also attached to which a flexible label 47 is attached. On the lower one At the end of the beak 12 there is a deployment guide element 48 which has an outwardly widening lower edge, and a spring is inserted into the guide tube.

cocked bumper 49 inserted. This rod is about that flexible control cable 47 and a relay housing 55 ″ which is attached to an underside of the internal line arm 15 is connected to a valve 50 (Pig. 6), which is in communication with a Yentil 51, which, as in the following, continues is to be described below, in the circuit of a power cylinder, which the vertical movement of the Schnabel 12 controls. In operation, the rod is when the rod 49 descends against the bottom of a sink to be filled thrusts, pushed up, and this movement is transmitted to the valve 50. As explained below should, this has the effect that the lowering movement of the beak is stopped and that the beak then is lifted for a short period of time so that the weight of the beak does not rest on the tanker truck.

The entire weight of the beak and its retaining device is balanced by the counterweight 60, which is attached to the inner end of the line section 30 is attached, wherein the mass of the counterweight is arranged on the opposite side of the axis of rotation extending through the swivel joint 28. Sin second counterweight 61, through which the weight of the outer arm section 16 and the beak hanging down from this section are balanced is attached to the knee 35, with the wet of the counterweight on the opposite side of the through the pivot joint 33 extends the axis of rotation.

A platform, generally designated 70 in FIG. 1, is fixedly connected to the knee 27 and extends around a relatively short piece in the horizontal direction in one level, that between the levels of the inner level Arm sections 15 and 19 lies. The platform comprises side parts 71 which, at their inner ends, are connected to the knee 27.

20981 4/0899

bound aind, and a pivot pin 72 is provided which extends between these parts at their front end. Each side carries a depending ear 73 in which a bore is formed, and the central upper edges of the Side panels jointly support a raised, open-ended housing 76.

Two slotted crank plates 80 are pivotably arranged on the pin 72. A double-acting hydraulic cylinder 85 is arranged between these plates, which is wedged onto the pin 72 and has hydraulic connection lines 86 and 87 Cross pin 89 which runs in the slots 90 cut in the sides of the panels 80 · This The transverse pin protrudes through the slots so that the inner ends of the gripping lever arms 95 and 96 can be pivotably attached to them, the outer ends of which are attached to them corresponding middle parts of the inner arm sections 15 and 19 are pivotably attached.

In operation, when the piston rod 88 moves outward, the spread between the arms and the Beak 12 is moved closer to the feed line 10 and vice versa. The distance between the axis of the pivot 28 and the pin 72 is substantially the same as that the distance between the pin 72 and the transverse pin 89 over most of the relatively short travel to work of the piston rod 88. Perhaps the device has a such a geometry that (when the piston is set in cylinder 85 in a given position) the beak runs up and down along a relatively straight vertical line when the device carrying the beak is in a vertical plane around the axis of the rotary

20981 /./0899

joint 28 is pivoted · This allows the raised Beak must be precisely aligned so that it enters the open hatch of the tank truck to be loaded.

The above-described vertical movement of the device about the axis of the swivel joint 28 is doubled by one acting hydraulic cylinder 100 generated, which is equipped with hydraulic connections 96 and 97 and the has on its front linden pivot pins which are rotatably mounted in the bearing brackets formed by the depending ears 73, so that the cylinder is movable in a vertical plane · This cylinder has a piston rod 101, which via a pin 103 is pivotably connected to the arm 102 of the crank plate 80 at its front end. When moving inwards the piston rod 101 into the cylinder 100 is moved via the crank plate 80 onto the articulated arms 95 and 96, thereby causing arms 17 and 18 and beak 12 to be pulled downward. A reverse movement takes place when the piston rod is extended out of the cylinder.

Conventional crouching devices, designated 110 and are rotated by the pin 72, and which cooperate with a follower 111, which is in communication with the hydraulic control devices, can can be used to set the limits of the upward and downward movement of arms 17 and 18 and thus that of them Arms held beak 12 set. Furthermore, the relay 55, which reacts to an upward movement of the rod 49 responds when the Sohnabel hits the floor of the tanker during its downward movement, with the hydraulic Control devices are connected to stop the further inward movement of the piston rod 101 and to cause

that this piston rod moves outward during a short time interval β, so that the beak a few inches is raised above the floor of the thank you to be loaded.

A third double acting hydraulic cylinder 115 is used to control the movement of the carrier device in a circle around the carrier line 10. This cylinder is at the top to perform a pivoting movement arranged on the platform 70 in the housing 76 so that it can perform a pivoting movement in a horizontal plane. This cylinder has hydraulic connections 116 and 117 and provided with a piston rod 118 which is pivotably connected to a crank arm 120 which is of the fixed part of the vertical pivot joint 26 protrudes from. Thus, a movement of the piston rod causes the knee 27 with the entire restraint thereon Device is rotated in a horizontal plane, so that the beak 12 is rotated on a circle around the fixed feed line 10 in one direction or the other, depending on the direction of movement of the piston rod 118.

The hydraulic controls for the three hydraulic cylinders 85, 100 and 115 are of conventional design and construction BchematiBch in Pig. 6 shown. The control for each cylinder 85, 100 and 115 can consist of a three-position spool valve 125, 126 or 127, which by setting the valve in one or the other of two of these positions causes the piston moves inward or outward in the cylinder. The third position is formed by a neutral position in which all lines to the cylinder are closed are so that a hydraulic locking of the cylinder is achieved and the device is fixed in the desired set position. With the pumps are

209814/0899

Lines 129 and 130 connected.

The hydraulic driving force for the device can be obtained by motor-driven and / or hand-operated rags, which are connected in parallel to one another on the main pressure line. In the outlet line of every pump there is a shut-off valve, and the power plant is protected by an adjustable pressure relief valve.

Operating mode;

The tanker loading device is held in a raised position at rest, so that the valley pipe does not interfere with the railroad cars passing under the device. The three are in this rest position hydraulic cylinders 85, 100 and 115 are hydraulically blocked by the associated valves. When a tanker is to be loaded, it is brought into a position in which is its hatch opposite the riser 10. A movable staircase can then be extended over the tank truck so that an operator on the stairs can open the hatch. Although the loading device according to the invention by controls at a location near the Riser can be operated, it is still desirable that a set of remote controls be provided which a push button device 135 (Jig. 6) provided by can be operated by the operator on the stairs near the hatch.

The operator first operates the swing cylinder 115 to rotate the device about the vertical axis of the pivot joint 26 so that the vertical plane of actuation of the device coincides with the center line of the hatch. Then he adjusts the reach cylinder 85 so that that the Palleitung 12 is above the center of the hatch. Closing

lent "he actuates the cylinder 100 for the downward movement, so that the palm line is lowered straight into the thank you. This movement is automatic by the plunger 49 on the the lower volumes of the palline 12 stopped, and the fall conduit is then automatically lifted a short distance from the bottom of the tank

When the charging process is complete, the reverse process takes place to bring the line back to its idle or idle state To bring memory position "

Although the present invention has been described on the basis of preferred exemplary embodiments, it is obvious that one skilled in the art can make many changes and changes without departing from the scope of the present invention leaving. For example, the riser 10 can go up instead of down, as shown in the drawing, can also be aligned in the weight compensation systems Springs or air accumulators can be used instead of counterweights · Electrical controls could also be used can be provided instead of the pneumatic controls described.
