Description

For cross-sectional dredging of an excavator, papilonaze imported bark with chains are usually used. In view of the slowness of work on installing korea and blocking the channel, a device is proposed with which the dredging machine is moved by pushing away so-called papilonaze sows that perform work automatically with the help of batteries.

FIG. 1 proposed mouth | x) gst: BO depicted in side view; FIG. 2 is a view of the svkhfu and FIG. 3-5 depict details of a battery water distribution device.

In the middle of the front frame of the excavator, in two thrust bearings (Fig. 1, 2), the arm F is fixed, which has a long leg on itself which carries a hydraulic device with all the distributing bodies and a piling head that serves to move the demoulder.

The papilonage specimen consists of two legs /, попере, which are alternately in operation and are designed so that at the end of the work the second automatically comes into play and vice versa. Each leg with its lower end, fitted with a shoe F, rests in the bottom of the slot; Shoe has a sufficient abutment. so as not to dig deep into the ground, and ridges protruding from below to reduce slip on the ground; Shoe with foot pivotally connected, but the angle of rotation is limited by a flange.

The upper end of the leg is provided with a head fastened to the slider P, with which the leg is pivotally connected with two mutually perpendicular axes, which is achieved by the fact that the head of the leg is hingedly fastened to the trunnions of the cruciform body F reinforced in the slider body also on the trunnions ( Fig. 2 and 1). The body M itself can rotate around the horizontal axis A. In agodar this combination, leg mo)

fixed slider; this latter, enclosed in the guides RR, can move in them under pressure from the piston of the hydraulic cylinder A. If the upper head of the foot /, which is in the nearest position to the hydraulic cylinder A, starts to press the roller from left to right, then the slider P will move along guides, pressing the excavator to the left, as the leg /, thanks to the emphasis in the bottom. can not move anywhere. A vertical upwardly developing force on the bracket F is absorbed by its own weight.

Thus, the machine will be moved by the piston stroke of the hydraulic cylinder. The sliders are connected between themselves by two toms (from Gall chains, etc.) attached to both ends of the slider (Fig. 2) —and slung one through the block E to the other — through block t. Therefore, when one slider moves out to the left to the right, it doesn’t move the other slider in the opposite direction; This movement is carried out by the pistons of the hydraulic cylinders AA, wherein, if the first water flows from the accumulators, the second cylinder is connected to the atmosphere and the water is squeezed out of it.

When the PI slider reaches its rightmost position, the (automatic) spool is re-circulating and water begins to flow into the second hydraulics, and the first is connected to the atmosphere. Then P comes into play and the cycle of work repeats.

In order for the idle leg not to be carried along the bottom and not knocked down by the current, the device automatically lifts it to the surface of the water so as to lower it to the bottom a little before the valve permutation of the hydraulics A-A. This is achieved by the following device: "At the end of the bracket F, there are two arrows D, D (Fig. 2 and 1) connected at the upper ends by an axis carrying two double rollers E, E. The arrows are supported by a cable thrown over

roller K, reinforced at the top of the bracket F; at which the cable rises or lowers manually and thereby changes the position of the arrows D, D. Blocks E, E are mounted on the b axis at idle and consist of a part of large diameter, which serves as a drum for the cable, reinforced by one end to the block, and the other to feet / - //, with which the diameters of the blocks are chosen so that when the block is rotated to a predetermined angle, the leg moves from the position / to the position // (Fig. 1). To bring the blocks into rotation, they are equipped with chain gears (Fig. 2). through which the Gall chains are thrown, attached ends to the piston of the hydraulic cylinder B; diving it, moving from right to left, chooses the Gall chain and, thus, takes out the leg P from the water. Conversely, if the hydraulics is in communication with the atmosphere, then the leg with its own weight falls into the water, while dragging away from left to right, and water is forced out of the hydraulics. Each leg has a separate hydraulic cylinder Bj, and the latter are not directly connected with anything, so it is equally possible either to lift the other leg alternately or both together.

When, after a series of movements, the car reaches the edge of the cut and, having made a ride on the main cable, must go in the opposite direction, the baggermaster makes a bracket toss to another side; at the same time, pre-removes both legs from the water. A hydraulic device C, C, operated by hand without an automatic drive, serves to rotate the bracket F. It consists of two CYLINDERS C, C, diving which are connected by a cable to a two-barred roller (Fig. 1), planted tightly on the bracket axis, and the cables, with their ends, are attached to the roller and, thus, hydraulics into which water from the batteries, no cable, rotates the bracket, pushing it to the small bed, holds it in this position until the baggermaster throws the valve manually, thereby letting water into another hydraulics. The water distribution devices of the hydraulic system for the operation of the legs / and // are shown in the sections in FIG. 3, where the axis L of the roller t (Fig. 1), which is connected tightly to it, is a hollow body into which water from the accumulator is supplied from the bottom through conduit M; the upper part of this axis is an intermediate member of the rela type, which serves to re-slide the Z slide. This last — ordinary flat spool — sits on a common rod with a piston of the cylinder x and moves from one extreme position to another, looking at which side the piston is given water from the inner cavity of the axis. This latter, turning at full stroke of the slider P at an angle of less than 360 °, gives water at one end of its turn to the right of the piston, at the other to the left of it and thereby produces a change in the course of the legs / and II. In the middle large section, the IV dispenser does not give water anywhere and the spool is B alone. To play the axial pressure on the junction box, there is a stop screw that passes through the Vphn cross-member, mounted together with the junction box on the installation bolts attached to the plate 5, S, on which the roller is mounted.

Pipe, going to the working hydraulics of the right foot. Has a branch to the hydraulics of the left foot and vice versa. Therefore, when the leg / is in operation, the leg // automatically rises. In the same way; at that time, the lifting arm of the working leg was connected to the atmosphere through the outlet valve of the slide valve, so that the leg remained lowered and free in its movements.

In order to lower the elevated leg with a certain preemption before the end of the working stroke, the hydraulics of the opposing & 4. The slider P at the end of the working stroke presses the roller q, seated on the lever and turns its Q axis to 5. When the slider P moves back, the spring immediately returns the lever and the axis

his former position. This axis 13 serves as a distribution body, a cylindrical spool located on top of the plate, on. which mounted polzushkI. This spool is shown in FIG. 4 is a top view, and on a larger scale, of FIG. 5. As can be seen from the latter, in the normal position of the Q axis, the W channels from the working hydraulics A are opposite to the W channel to the sub hydraulics In this leg, i.e., crosswise in accordance with the above.

From the moment that the slider starts to press the lever, these channels separate and a direct connection of the channel W from the hydraulics of the raised foot to the atmosphere is established, the consequence of which is that the foot drops into the water a little earlier than the main slide 3 is turned. to raise the leg in accordance with the arbitrariness of the bagmemeister, it is necessary to give the working hydraulics to the working hydraulics (for the already elevated) water from the accumulator is not working; For this purpose, the pipeline M serves, which is locked by a valve located under the hands of the baggermeister and usually closed. If it is opened, it gives water through a pipe to both hydraulics under lift, while the hydraulics of the working leg, connected to the atmosphere through the outlet valve of the spool Z, will receive a jet of iodine, which will activate it and lift the second leg. To prevent water from flowing from the pipeline into the outlet of the spool z, a check valve T is installed, and so that the water from the operating sub-hydraulics does not get into idle - through the connecting pipe, there are check valves T and T °.
