Description

TECHNICAL FIELD

[0001] The utility model relates to the auxiliary equipment technical field of ship unloader, and concretely relates to a material receiving plate for bridge type grab ship unloader. BACKGROUND

[0002] The bridge type grab ship unloader is widely applied in domestic and foreign bulk cargo unloading operation due to its high operation efficiency and strong flexibility, however, the bridge type grab ship unloader will pollute seawater environment and increase cleaning work due to the problems of material falling off from the bottom of the grab, material blocking and not being tightly closed, and material spilling along the way during the transfer process from the ship cabin to the unloading hopper.

[0003] The traditional material receiving plate of the bridge type grab ship unloader is lifted up in the non-operation state to meet the non-interference of the ship, and the length of the material receiving plate is fixed due to the influence of the structure height of the main beam, so the length is limited and the material spilling outside the receiving range is prone to occur.

[0004] How to solve the problem of material spilling between the material receiving plate and the ship during the unloading process of the bridge type grab ship unloader, which pollutes seawater and increases cleaning work, has become one of the difficult problems for port operating units to solve.

[0005] For example, the Chinese utility model patent with the authorization announcement number CN 214399057U discloses a flexible material receiving device of ship unloader, which comprises a material receiving plate hinged on the ship unloader, a driving member fixed on the ship unloader, pull rods I arranged on both sides of the material receiving plate, pull rods II connected with the pull rods I through air springs, the pull rods II moving with the movement of the pull rods I, a fixing member arranged on the material hopper platform and used for fixing the pull rods II, a bottom of the material receiving plate provided with a rolling track, and a roller arranged on one end of the driving member close to the material receiving plate and used for moving on the rolling track to realize the action of the material receiving plate. The utility model stores and releases the energy generated by the impact of the grab on the material receiving plate in the air spring, avoids the deformation of the material receiving plate caused by the impact, and separates the driving member from the material receiving plate during the operation of the material receiving plate, so the overall service life is high and the maintenance cost is low. However, the material receiving device is separated by moving the material receiving plate through the rolling track and the spring, the structure is relatively complex, and the spring will fail after a long time of use.

[0006] For example, the Chinese utility model patent with the publication number CN 203402850U discloses a bridge type grab ship unloader, which comprises a steel structure system, an operation system and a discharging system, wherein the discharging system comprises a receiving plate system, a hopper and a feeding belt conveyor, the receiving plate system comprises a sea side receiving plate, an intermediate receiving plate and a land side receiving plate, and the sea side receiving plate, the intermediate receiving plate and the land side receiving plate are respectively installed on a sea side stand, the hopper and a land side stand. The ship unloader has high operation efficiency and maximized production capacity, and can meet the requirements of stopping large ships at the wharf and discharging materials in the sea and land directions due to the large extension distance of the sea and land sides and the three-pole form. However, the receiving plate system is fixed on the frame, the length of the receiving plate is fixed, the length is limited, and the material outside the receiving range is prone to be scattered.

[0011] Preferably, the main plate is connected to the sea side hopper mouth of the receiving hopper in a hinged or hinged manner.

[0012] In any of the above schemes, preferably, one end of the auxiliary plate is connected to the main plate in a hinged or hinged manner, the auxiliary plate can rotate around the hinge point or hinge pin, and the rotation range is between the working position and the rest position.

[0013] In any of the above solutions, preferably, the electric push rod device comprises a base, a push rod and a supporting plate, the base is connected to the two ends of the main plate by means of bolted connection and can rotate with the auxiliary plate; the push rod is a telescopic electric push rod (the telescopic range meets the rotation of the auxiliary plate from the rest position to the vertical position), one end of which is connected to the base and the other end of which is connected to the supporting plate; the end of the push rod is provided with a bearing, and the supporting plate can rotate around the bearing in the push rod to adapt to the angle change of the auxiliary plate and always adhere to the auxiliary plate when the auxiliary plate is over the vertical position.

[0014] In any of the above solutions, preferably, the end of the auxiliary plate away from the main plate is connected to the auxiliary plate winch through a rope.

[0015] In any of the above solutions, preferably, the end of the main plate away from the receiving hopper is connected to the main plate winch through a rope.

[0016] In any of the above solutions, preferably, the width of the auxiliary plate is less than or equal to the width of the main plate.

[0017] In summary, the receiving plate for the bridge type grab unloader of the present application has the following advantages: after the auxiliary plate is unfolded to the working position, the length of the receiving plate is doubled, which can effectively reduce the pollution caused by the scattering of materials to the environment and reduce the cleaning work; after the auxiliary plate is recovered to the rest position, its size does not affect the main arrangement of the conventional bridge type unloader.
