- the invention relates to a drive device for a gripping device with two gripper arms that can be moved like tongs, preferably for a clamshell bucket, consisting of two hydraulic swivel motors, the projecting over the motor housing
- the pivot arms of the swivel shaft carry the gripper arms.
- the shells are supported Provide shafts with radial levers on which the piston rods or cylinders are articulated by hydraulic piston-cylinder units to the closing and Transfer opening forces to the waves.
- a known from DE 34 25 035 A1 Clamshell buckets are characterized by a low height that the hydraulic piston-cylinder unit consists of two each on the operating levers of the shaft-articulated cylinders, the pistons of which are common Piston rod are interconnected.
- Such clamshell buckets must be provided with relatively large hydraulic cylinders, because change the effective lever arms of the operating lever with the swivel angle and can assume relatively small effective lengths, with additional the disadvantages are that the hydraulic cylinders partially open the shells cover and also represent vulnerable components during operation of the clamshell grab can be damaged.
- DE-GM 296 21 601.1 is a clamshell bucket of the type specified Kind known in which the drive for the shafts supporting the shells in the Shell carrier is integrated.
- This known clamshell bucket has none the absorbed material at risk because the two hydraulic Swivel motors are encapsulated in the shell carrier.
- Each swivel shaft of the swivel motors is a clamshell bucket with several provide radial rotary lobes which are concentric to the shaft axis Grab chambers of a cylinder, the chambers through one of the Number of rotary pistons corresponding number of radial indentations from each other are separated and the rotary pistons with their apex areas sealing the chamber walls and the recesses with their apex areas on the Swivel shafts are present.

- each of the swivel motors has a cylindrical piece of pipe which on its inner wall with a an internally threaded portion is provided with a with a Threaded portion of the pivot shaft is engaged that the Pipe piece an axially displaceable cylinder space formed in one of the housings, but rotatably held ring piston is that the pitch of the thread so is great that the ring piston by its axial displacement of the swivel shafts the necessary torque can give, and that the displacement of the Annular piston between the two annular cylinder chambers, which alternate high and low pressure chambers that can be loaded with hydraulic oil are the desired ones Swivel angle of the two shells corresponds.
- the drive of the clamshell grab according to the invention is characterized by this by a simple and robust structure that only by axial displacement the ring piston is given the required swivel movement.
- the ring piston can be secured against rotation, for example, from a in the cylinder wall exist axially extending groove into which is connected to the annular piston Pin or wedge engages.
- the pitch of the thread can be chosen so that the shell on the swivel shafts exerted torque as a result of self-locking the ring pistons cannot move even with unpressurized cylinder chambers. Become the ring piston does not move due to the pressure of the hydraulic oil Shells cannot be swiveled due to external forces. This required Self-locking is achieved in that the thread pitch is so large that the desired large torque by the axial displacement of the annular piston is transmitted to the swivel shafts.
- the thread webs advantageously have trapezoidal cross sections that are characterized by good stability.
- the drive of the clamshell grab according to the invention is maintenance-free because the ring piston runs in the hydraulic oil.
- the two Ring pistons are connected to each other by a cross bar. This crossbar ensures the synchronous operation of the two ring pistons, so that common synchronizing linkage are no longer required.
- the shell carrier preferably consists of two housing halves screwed together, each with two bearing bores for one side of the Swivel shafts is provided.
- Threads of the shafts are located in and in only one half of the housing Half of the housing is formed a first cylinder chamber, the circumferential shape of the corresponds to two annular pistons connected by the web, and that the peripheral shape with these seals against the first cylinder chamber is provided.
- the peripheral shape can consist of two mutually parallel sides, the ends of which are connected by semicircular arches.
- the second cylinder chamber can be formed in the other housing half, in which the annular pistons projecting beyond the web in the end regions of their bores Ring seals are provided, which this against thread-free sections of the Seal swivel shafts.
- the Shell supports projecting shaft journals of the swivel shafts with coupling devices are provided for coupling the shells. These can, for example from half shells connected to the shells and screwed together exist, which are coupled to the shaft journal by bolts, the aligned Drill cross holes in the half-shells and the shaft journals. To this A simple quick change system is created in this way. Shells different Width can be provided with adapter pieces adapted to the shaft journals his.
- plug-in couplings for establishing the connections with the Shaft of a rotary motor penetrating hydraulic lines consisting of axial bores are arranged.
- the shaft of the Rotary motor with rotary unions for the supply and discharge of hydraulic oil to the Swivel motors of the clamshell grab provided.
- the one with the bowl carrier coupled end face of the shaft of the rotary motor opening hydraulic lines can be designed as counterparts of the plug-in couplings on hollow peg-shaped counterparts of the shell carrier are attachable.
- the clamshell bucket according to the invention consists of a shell carrier 2, in the pivot shafts 3, 4 are rotatably mounted, the shaft journals 5, 6 on both sides protrude the shell carrier. With the shaft journals 5, 6 are the two shells 7, 8 coupled.
- the inner U-shaped reinforced frame profiles 9, 10 of the two shells on the upper end faces of their legs in Cross-section of semicircular shells, which thereby the projecting shaft journals 5, 6 border that they are screwed to the side flanges of holding parts 11 are also with bowl-shaped recesses with semicircular Cross section are provided.
- the shells, holding parts and shaft journals are provided with aligned bores 12, 13 into which a retaining bolt 14 is inserted is.
- the shell carrier 2 consists of an essentially rectangular housing opposite narrow sides 15, 16 rounded approximately semi-cylindrical are.
- the housing consists of two roughly divided housing shells 17, 18, which are screwed together in their parting plane by clamping screws 19.
- the housing 17, 18 is provided on opposite sides with bearing bores, in which the pivot shafts 3, 4 are mounted.
- the holes are with Provide annular grooves 19 in which the shaft ends sealing ring seals are inserted.
- the pivot shafts 3, 4 have a threaded section 22 provided.
- cylindrical pieces of pipe 23, 24 placed on its inner wall with a section C with a Internal thread are provided with the thread 22 of the pivot shafts 3, 4 in Intervention is.
- the cylindrical tube pieces 23, 24 are interconnected by a web 25 connected.
- This web 25 is located on an outside of the cylindrical Pipe pieces 23, 24 so that they project beyond the connecting web 25 towards the inside.
- they point through them connected cylindrical tube pieces an outer peripheral shape with a cross section on, which consists of two parallel sides that pass through on their narrow sides Arch are connected with a semicircular cross section.
- the housing shell 17 is provided with an inner peripheral wall, the shape of which is complementary to that outer shape of the pipe sections 16 interconnected by the web 25 in Area of the connecting web is.
- the through the connecting web 25 with each other connected pipe sections 23, 24 are in the region of the connecting web by a circumferential seal, which is inserted into a groove 28, sealed.
- cylinder chambers 33, 34 formed, which alternately pressurized with hydraulic oil and be connected to low pressure lines to drain hydraulic oil.
- the teeth 22 and the internal teeth of the pipe sections 23, 24 exist from threads with a trapezoidal cross-section.
- the threads have such a pitch that the pipe sections 23, 24 one have such a large distance from a self-locking that they the swivel shafts 3, 4 can give the desired torque.
- This big thread pitch on the other hand leads to a self-locking of the threads, as far as this a greater force is transmitted via the gripper shells 7, 8.
- the pipe sections 23, 24 can also each without the connecting crossbar Ring piston be formed, which then in cylindrical cylinder chambers Shell carrier are performed. However, in such an embodiment it is Basically necessary, balancing linkages guaranteeing a synchronism of the gripper shells provided.
