SU57028A1 - Gripping beam for raising and lowering sandals in hydraulic structures - Google Patents

Description

The invention relates to devices for lifting and lowering shandors in hydraulic structures and is intended to facilitate heavy and cumbersome maneuvering by shandors, to reduce the time required for installation and disassembly of the barrier than, consequently, to reduce the cost of these operations.

In the proposed gripping beam, well-known hooks and flip levers with cargo are used, which are used for the automatic coupling and disengagement of the hook with the Sandor when it is raised and lowered. A new feature of the design of the proposed gripping beam is that the flip levers have sectors with an arcuate slot in which the pin of the hinge pivotally attached to the pivot hook moves.

A device for warning can be placed in the catch beam to wait for the premature disengagement of the hook from the shaidor.

A chain drive can be used for interlocking hooks.

A gripping beam can be used as an upper chandelier, for which it must have vertical water-boring walls and sealing devices.

The girder can also be used as a pedestrian bridge, for which it must be equipped with rails and rails.

The proposed gripping beam can be used to maneuver the Shandor, both main and repair: and emergency barriers at shipbuilding and ship repair yards at large docks and semi-locks, as well as repair barriers on waterways at large locks.

The drawings depict an exemplary constructive 0 formation of a barrage and devices used to maneuver the tandors using the proposed gripping beam.

In the device depicted in the drawing, upper spanner, in addition to its primary purpose, uses:

1) as a bridge for the movement of the traverse carriage 2 mounted on it, which serves to be suspended thereto on Sandor 3 lines while moving it over the construction opening (Figs. 1, 2, 12, 13, 23 and 24);

2) as a pick-up beam, by hanging it by detachable earrings 10 on the chain hoists 4 to the cargo winches of cranes 5 and immersed in water together with the overturned barrier, as well as in the case of disassembling the barrier by capturing and lifting the next offshore from the water (FIG 7); 3) as a service bridge for the pedestrian traffic of the right bank with the left bank (Fig.), For which it is supplied with railings and railings that are folded along it.

The installation of the upper sandstone (gripping beam) in the position above the opening hole or its removal to the coast (Fig. 9, 11 and 12) is accomplished with the participation of one of the shandors and two Sandor carts 6, moved by means of a cable thrown through the system of blocks 8 from winch 9 (Fig. 1 and 2) crane 5 to the spindle trolley. One of the two carriages (furthest from the coast) is loaded with ballast that does not extend beyond the bogie's dimensions and does not exceed the weight of the upper girdle; Shandors are centered between each other by means of guiding wedges 60 and secured with anchors 7 (Figs. 11-16, 25 and 26).

Upper Shandor 1, unlike

the rest of the shandors, perceives mainly the vertical load of the weight of the sandstone suspended to it through the traverse carriage, with a relatively small horizontal force on it from the pressure of the water. Therefore, the upper sandstone consisting of two vertical longitudinal walls covered with top and bottom HYRIZONTAL LISTS1M: And,

 much smaller width in Plan. A rail track 11 is mounted on the upper plane of the rail for moving the carriage 2 with the crosshead. Tr-obverse (Figs. 23 and 24) is formed by two transverse beams 12 rigidly interconnected. At the ends: of the beams, there are bolts 13, supporting the loops 14 with slings 15 and hooks 1-6 suspended from them. In line with this, all the shaidors, except the top one, are supplied at the ends with cargo brackets 17 for suspending them from a hook 16 of the slings 15 of the traverse trolley 2 for the time the shandors are stirred within the orifice. The traverse is supported in its middle part on the frame 18 of the carriage, rolling on four wheels 19 along the rails of the upper girdle. A characteristic feature of the upper Shandor is the equipment of its end parts within the groove with grippers (Fig. 3, 5, 19-22). The latter are located in the cavity between the ends of its vertical longitudinal walls, with both ends of the chandelier symmetrical. In the upper-most corner, on the transverse pin 21, two earrings 10 are attached for the suspension of the sander to the hoist's hoist tacks (Fig. 1 and 2). At the ends of all the sandals on the elastic rubber strips, roller bearings 20 are located to avoid longitudinal displacement (Figs. 2, 3, 15, 16, 20). In the lower part of the end of the upper chandelier (fig. 19-22), the gripping hook 23 is pivotally suspended on the axis 22, on the outer face of which there is a guide bar 24 on the bottom. The hook axis 22 is fixed in brackets 25 and 26. In the upper part of the hook there is a spur 27 pivotally connected to the lower end of the pull 28. The upper end of the pull may be moved along the arcuate slot 30 of sector 31 by finger 29. Sector 31 is part of the overhang lever with weight 32. Lever with sector, set on the key on the roller 55 can rotate with it. The support and bearings for the roller, located in the same vertical plane with the axis of the hook, but higher than it, are the above-mentioned brackets 25 and 26. The same roller is set on the key block 34 with a light cable 55 attached to it, two branches of which hang from the block chugs and terminated by rubber balls 36 and cushions 37, serving as the front weight of the weight; in different positions.

In the presence of an articulated hook with a sector, the following two basic states of the system are seen, depending on | counterweight position. The left counterweight (Fig. 19) - the hook, under the action of its own weight, maintains its vertical position, i.e., it transfers it to the linking position. On the one hand, limiting the movement of the sector with a counterweight are the restrictive 5S rod, which goes across the top spindle and rests on its longitudinal walls, and on the other hand, buffer 39 placed on the bottom of the shoring. However, a safety lever 40 with a stop may prevent the sector from moving from the left to the right. The latter is hingedly suspended in a plane perpendicular to the plane of rotation of sector 5 /, to a brace 41 attached to the wall of the chandelier, and in the position indicated in FIG. 22, the roller 42 rests against the protrusion 43 of the rod 44. This rod can vertically mix in the guides 45 and 46, however, to a limited extent, thanks to the stopper 47, abutting the bracket projection 48. Exceptionally, however, the shtanga is located in a lowered (as shown in the figure) position under the action of its own weight and spring 49, raised only when it rests with its lower end about some obstacle npia lowering the gripper pole. With the lift of the rod 44 upwards, the roller 42 will roll along

the face of the protrusion 43 obliquely downwards and the safety lever 40 will lower, due to which sector 31 supported by it from the left position I (Fig. 20) under the action of the load 92 will descend to position III and IV, through position II to the buffer 39 and transfer the gripping hook to the horizontal position for disengagement.

In order that the release of the catch hooks with cargo crosspieces of a sanding rod suspended from them could only occur with the correct sweetness of the latter into the barrier to the previous one, all serial sandals must also be equipped with safety bars 51. These rods are smooth (without projections) freely laid from the top into the holes made for them in Shandor strictly on the same vertical axis with the rod 44 of the gripping chandelier, is, as it were, its continuation. Each length of the safety bar 51 corresponds exactly to the height of the given chandelier and, at its upper end, has a bearing head 52 which keeps it from falling out through the direction of the hole 1 of the hole. The supporting plane of the head is chosen so that when the maneuvering1I1 and the lower end of the rod are several, it protrudes beyond the limits of the plane of the lower crossbar of the Shandor. Thus, when lowering the lower pitch is lowered into the grooves of the barrier, the safety bar only if it is correctly installed will first be put into the bottom of the structure or into a special pin in it and by the time of installation it will be in the plane of the upper horizontal bars 53. When lowering the following shandors, the rods will rest in the heads of the rods of the previously laid shandors.

FIG. 19 .and 20 shows the different positions of the catch hook.

Coupling, when disassembling the barrier, takes place (. It comes up 1 I by: pulling the corresponding end of the cable 55 hanging from the block 34 into the position shown in Fig. 19. At the same time, the toggle lever with sector 31 abuts the restrictive rod 55. As the visor is lowered due to the hook guide usa 24, sliding along the cargo crossbar 50 of the saddle 3, the crank deviates from position I to position II, while slightly lifting the load-carrying sector 31. on hook spur 23, n Latter again returns to the vertical position. Thus, at the subsequent lifting hook zabralnogo Sandor It appears in position III bonding. Moving the rods 44 is accomplished in this case idle.

Disengagement during the assembly of the barrier occurs by placing the inverse lever with the sector in the position shown in FIG. 20, also by pulling the corresponding end of the cable 35; at the same time, the sector rests on the safety stop of the lever 40. By the time when the lowered sandor is 3 liters on the bottom of the IL1N previously laid into the barrier, the safety rod of its 51 will occupy the position shown in FIG. 20. Upon further lowering of the upper pitch, the shed of the hook will come out of engagement with the cargo transverse 50 and, slipping on it, will be deflected to the position shown by dotted lines. At the same time, the rod 44 will be supported on the head of the safety rod 5 / sandor, and the safety lever 40, incidentally with its roller rolling 42 along the protrusion 43 of the rod, is lowered to position W, IV (Fig. 22) under the pressure of sector 31. Immediately after at the same time, the latter is carried by load 32 also to position III (Fig. 20), lifting the gripping hook from the cavity of the chandelier to the horizontal position III and then IV by means of the pull-rod 28.

To block both flip levers with sectors located on the rings of the upper Shandor, as well as for one-time (co-transfer them from one position to another, i.e. interlocking the IL | And uncoupling, the following device is used (Fig. 21 and 36). In common with the sector and the block 34, the roller 33 is fitted with an additional: telvy chain block 54. Short chains 55, covering both chain blocks 54 at the ends of the upper girder, are interconnected by a crossed cable 56, as a result of which they are forced to rotate than investigator but, and achieved their blok1irovka.

The grippers with safety devices and locking devices 1 described above ensure that the gripping hooks of the upper shandor are unhooked from the cargo crossbars 1and the chandelier immersed in the hole only if it is properly laid into place, preventing the tripping, which is possible in conventional structures of excessive external resistance on the way during lowering shandor into the hole. This ensures the reliability of the hooks and the trouble-free maneuvering of the pins.

Disengagement of the gripping hooks after lowering the sandstone taken out of the hole to the end trolley 6 (position b in Fig. 7) brought under the ends is similar to discharging under water during installation, for which the saddle trolley 6 is provided with protrusions 6a corresponding to the protruding lower ends of the safety rod rotor ( Fig. 1).

With the use of the described equipment, the following order of maneuver is assumed when dismantling the Skording barrier.

Tensioning the corresponding end of the cable 55 with the rod 37, hanging from the top end / mounted on the chain hoists 4, transfers sector 31 to the engaged position. The gripping beam or upper sandor / is lowered into the grooves before it is in contact with the lifted shandyr (for example, with the pivot .3), and the gripping hooks automatically engage the cargo cross-pieces. Immediately thereafter, the cargo winches are switched to a hoist, and the upper shandor / with the saddle 3 rises to a certain discharge level. Under the ends of the lifted shandor, on both sides, two sandor plates are fed.

trolley 6, and the sector 31 using the corresponding end of the cable 35 is translated into position e of the trip. The winches are turned on (on descent, moreover, as described above, when the protruding lower ends of the safety rods are supported onto the corresponding projections of the pallet trucks, the hooks are automatically disengaged and removed from the cavity of the lifted palder.

Next, the end of the lifter, opposite the shore, to which it is supposed to be rolled out, is hung on the hooks of the slings of the traverse trolley 2. To simplify the transfer of part of the weight of the sander to the traverse trolley, i.e., to tension the slings of the traverse, as well as other operations, it is desirable to use trolleys with lowering platform; However, the possibility of using simple trolleys is not excluded, which only increases: the number of operations with cargo winches (pickling and the choice of the cable of the polyspasts) 1I, therefore, will slightly lengthen the total maneuvering time. In this way, the sandal rod is at one end suspended from the traverse carriage, and the other is supported on the road carriage. In this position, the sandstone rolls away to the side of the shore, as far as the movement of the trolley with the crosshead along the upper sandwalk allows, and is separated from it after the second trolley is brought under it to roll back to the storage location. Immediately, then, the gripping hooks are charged onto the clutch and the upper girdle is again lowered into the water to lift the next gander.

The rise of the following chandors p-ro1 is in the same order.

At the end of the dismantling of the barrier, the upper sandstone either plunges into a horizontal groove in the bottom of the structure or rolls ashore with the participation of one of the spiers (Figures 9-11).

When installing spindles in the construction hole, the described order is manojouriated (produced in reverse order.

Side sliding barriers are provided in the sand barrage (Fig. 3-6).

and guide pins 57 and 58 on elastic gaskets. The provided symmetrical holes 59 in the pins (Figs. 2 and 16) allow the permutations of the said stops from one side to the other depending on the change of direction of the hydrostatic pressure, which eliminates the need to rotate the pivots in the plan by 180 ° and the position of the fixtures in grooves (Fig. 27).

By using the guide wedges 60 and the sockets 61 (Figs. 25 and 26), it is intended to achieve precise centering of each shandor relative to the underlying, correct placement of all shandors in the grooves and thereby ensure the most reliable operation, vertical anti-filtration seal.

A device consisting of two metal corners 62 in the entire height of the barrier (Figs. 28-35) can be used for vertical vertical filtration seals in the slots. The outer sides of the corners all over are covered with two layers of rubber 63 lying on top of each other, fixed to it by means of bolggs with nuts and washers, or attached with adhesive. The side edges of the rubber layers are longer than the ends of the corner shelves and are pointed. The lower end of the corner is also formed by a rubber kerchief 65 with a hole 66, which is trimmed with rubber. Two such corners are installed on the upper side of the barrier at angles formed by the walls of the structure and a number of vertical (side) sealing bars of sandals (Fig. 6). The hole in the lower end of the corner is mounted on the centering pin 67 specially mounted on the bottom of the structure (Fig. 27), and the upper end is fastened to the assembled barrier by a bolt 68 of the folding bracket: Tein 69 (Fig. 34 and

35) rotating on the pin 70 embedded in the wall of the upper span. With the pa3o6paHHOMi barrier, the corner is retracted into the groove by pushing the ring 72 using a cable attached to the kerchief 71 in the upper part of the corner.

The subject matter of the invention.
