Canal bottom-opening sand transport ship mud door opening and closing device and use method thereof

Abstract

The invention discloses a canal bottom-opening sand transport ship mud door opening and closing device and a use method thereof. The canal bottom-opening sand transport ship mud door opening and closing device comprises a ship body and a control console, mounting grooves are formed in the middle positions of the two ends in the ship body, hinge shafts are arranged on the two sides of the top in the ship body, and sand storage grooves are hinged to the inner sides of the two hinge shafts; mounting plates which are connected with each other are arranged at the tops of the two groups of mounting grooves; through two groups of same hinged linkage structures, the sand storage tank obtains a limiting and unfolding function under the movable matching of a hinged plate and the pressing matching of a pressing wheel and a sliding groove, and in the sand storage tank unfolding period, through the elastic compression of a coil spring and the winding and rotating matching of a rope and a rope wheel; the sand storage tank is further subjected to an auxiliary positioning function of four groups of ropes during unfolding work, so that the stability and the balance effect of starting and closing operation of the sand storage tank are greatly improved, and shaking and rolling generated during operation of the device are reduced.

Description

technical field [0001] The invention relates to the technical field of sand transporting ships, in particular to a mud door opening and closing switch device for a canal bottom opening sand transporting ship and a method for using the same. Background technique [0002] The sand transport ship is a special machine for mining sand in the river. It is composed of a floating body floating device, equipped with an excavation device, a screening device, a storage bin, and a transmission device. Whether the mud door of the storage bin of the sand transport ship is in use Normal opening and safety during use have always been the focus of industry awareness; [0003] When the mud door of the current sand transport ship is opened, the two sets of sand holding tanks are generally disconnected downward from the middle to form an unfolding mechanism, which promotes the material sand to fall into the sea surface for reclamation work. The contact with the sea surface creates a certain pr...

Problems solved by technology

[0003] When the mud door of the current sand transport ship is opened, the two sets of sand holding tanks are generally disconnected downward from the middle to form an unfolding mechanism, which promotes the material sand to fall into the sea surface for reclamation work. The contact with the sea surface creates a certain pressure, so that the active points of each part cannot be kept straight, and the components are easily damaged under the pressure of the water liquid, and during the operation, the ship will be in contact with the water liquid, causing the overall hull to be loaded, resulting in a greater impact and vibrations, causing the hull to shake and shake, which not only causes the transported sand to fail to discharge normally, but at the same time, as the shaking amplitude gradually increases, it may cause the hull to overturn as a whole, causing safety hazards, and increasing the use of the existing mud door opening and closing work It is inconvenient and reduces the safety of the staff and the practical value of the device. When the mud door is closed, it is easy to bring too much water into the stagnant sand tank, which is not easy to discharge, and during the movement of the hull, the water may be contained in the sand tank. Seepage from the cracks causes the hull water to rise, making the operator unable to know immediately, increasing the operator's workflow and reducing the efficiency of water discharge. The mud door of the sand tank is not required to be frequently opened and closed. , however, the opening and closing switch is generally installed directly in the cab. If the operator does not touch it during driving, it is easy to cause the transported sand to flow out directly. During the inspection and maintenance of the mud door structure, the operator should not touch , may cause the operator to fall directly into the sea, reducing the safety protection function of the device
