Description

Technical Field

[0001] The invention relates to the technical field of ship repair and construction, and in particular to a replacement device for a lifting belt of a self-unloading ship. Background Art

[0002] A self-unloading ship is a dry bulk cargo transport ship that can unload cargo in a continuous conveying manner. The conveyor belt is an important carrier for the self-unloading ship to continuously convey cargo. Therefore, when designing and manufacturing a self-unloading ship, the installation of the conveyor belt becomes a top priority.

[0003] Since the conveyor belt is an important carrier for transporting goods, it is inevitable that it will be worn out or aged during use. If the belt is aged or other accidental accidents occur, it will inevitably lead to the interruption of cargo transportation, which will affect the transportation of freight. Therefore, the conveyor belt needs to be monitored and replaced according to the actual situation. However, in the current design of self-unloading ships, only the process of entering the cabin for the installation of the conveyor belt is designed, and the replacement of the conveyor belt is not designed. Therefore, when replacing the belt, the old belt needs to be slowly lifted out of the cabin by an additional crane, and then the new belt is lifted in, and finally the replacement is completed. This replacement method invisibly wastes time and is not convenient and fast enough. Therefore, many manufacturers have designed conveyor belt devices.

[0004] In the prior art, a special double belt reel support is designed, on which a full roll of new belt and a bare reel for collecting old belt are placed. Then, during use, the old belt is cut, and then the new belt is connected to the old belt. The old belt is pulled out by using the reel and the lifting motor of the self-unloading system, and the new belt is put into the warehouse. Then, the connection between the old belt and the new belt is cut and combined with the other end of the new belt to complete the belt replacement. For this replacement method, it needs to be used under certain conditions, because the new belt needs to be pulled in a direction when entering the warehouse, and the old belt can play a traction role when the old belt is intact. When a part of the old belt is broken, more seriously, if a part of the old belt is broken, and the space at the break is small, the maintenance personnel cannot enter. Under the above two conditions, the use of traditional belt replacement methods is completely impractical. Therefore, it is particularly important to design a belt replacement device for self-unloading ship belts under the condition that a part of the old belt is broken. Summary of the invention

[0005] In order to solve the above technical problem or at least partially solve the above technical problem, the present disclosure provides a device for replacing a lifting belt of a self-unloading ship.

[0006] The present invention discloses a replacement device for a lifting belt of a self-unloading ship. The device includes: a belt that is wound around a driving roller and a transmission roller, and the driving roller and the transmission roller are supported on a frame. A guiding groove is provided on the frame near the driving roller and the transmission roller, and a steel wire rope is arranged in the guiding groove. One end of the steel wire rope is wound around a first steel wire rope reel, and the other end is wound around a second steel wire rope reel. The first steel wire rope reel and the second steel wire rope reel are both supported on the frame. The second steel wire rope reel is located on one side of the first steel wire rope reel. A new belt reel and an old belt reel are further arranged on the frame, and the new belt reel and the old belt reel respectively form an integral reel or a split reel with the first steel wire rope reel and the second steel wire rope reel.

[0007] Further, the first central axis of the first steel wire rope reel and the new belt reel is connected to the inner ring of a first bearing, and the outer ring of the first bearing is connected to the new belt reel. First flange plates or first electromagnetic clutch plates are respectively provided at the opposite end portions of the first steel wire rope reel and the new belt reel, and a first reel driver is provided at one end of the first central axis.

[0008] The second central axis of the second steel wire rope reel and the old belt reel is respectively connected to the inner rings of a second bearing and a third bearing, and the outer rings of the second bearing and the third bearing are respectively connected to the second steel wire rope reel and the old belt reel. A middle piece of a two-way flange or a middle piece of a two-way electromagnetic clutch is connected to the second central axis between the second bearing and the third bearing. Left and right pieces of a two-way flange or left and right pieces of a two-way electromagnetic clutch are respectively connected to the opposite end portions of the second steel wire rope reel and the old belt reel, and a second reel driver is provided at one end of the second central axis.

[0009] Further, first steel wire rope reels are respectively provided on both sides of the new belt reel, and second steel wire rope reels are respectively provided on both sides of the old belt reel.

[0010] Further, a plurality of connecting rods are evenly arranged on the steel wire rope. One end of the connecting rod is connected to the steel wire rope through a hinge ring, and a first hook is provided at the other end of the connecting rod.

[0011] During the replacement process, the fixed connecting rod is pulled out by rotating the hinge ring, and then the first hook arranged on the fixed connecting rod is connected to the connection port of the new belt, thereby achieving the purpose of pulling the new belt. When not in use, the fixed connecting rod can be retracted into the guiding groove to avoid the fixed connecting rod from obstructing the transportation of goods.

[0012] Further, a connection hole is provided at the end of the new belt on the new belt reel, and the first hook is connected to the connection hole.

[0013] Further, a plurality of connecting rods for detachable pull rods are evenly arranged on the steel wire rope. One end of the connecting rod is connected to the steel wire rope through a hinge ring. A first hook is provided at the other end of the connecting rod. The first hook is connected to the end of the pull rod. The pull rod is located between the two steel wire ropes.

[0014] Further, a plurality of second hooks for connecting with connection holes provided at the end of the new belt are provided on the pull rod.

[0015] Further, the cross-section of the guide groove is C-shaped. The diameter of the steel wire is greater than the opening of the C-shaped. The guide groove is circularly arranged in a week outside the two side edges of the belt.

[0016] Further, the guide groove is circularly and continuously arranged in a week outside the two side edges of the belt, or is arranged in a week at uniform intervals.

[0017] Further, a first pressure roller is provided between the new belt reel and the driving roller, and a second pressure roller is provided between the old belt reel and the driving roller.

[0018] The technical solution provided by the disclosed embodiment of the present invention has the following advantages compared with the prior art: In this application, guide grooves are installed on both sides of the driving roller, and steel wire ropes are provided in the guide grooves. When the middle of the old belt breaks, the old belt cannot play the role of traction, and the design of the steel wire rope can play the role of traction and can replace the new belt in special cases.

[0019] Due to the lack of traction, it is necessary to connect the new belt to the steel wire, and the steel wire plays the role of traction to guide the new belt into the cabin. Two holes are provided at one end of the new belt and are connected to the steel wire through the holes. After the operation of the new belt entering the cabin is completed, in order to ensure the various characteristics of the new belt, the part with holes needs to be cut off, and then the connection operation is carried out.

[0020] The working method of the present invention is as follows: Before use, first connect the old belt to the old belt reel, and then connect the middle piece and the right piece of the two-way flange or two-way electromagnetic clutch, that is, connect the flange or electromagnetic clutch piece connected to the drive shaft to the flange or electromagnetic clutch right piece connected to the old belt reel. After starting the second reel driver, the drive shaft can drive the old belt reel to rotate, and then pull the old belt out of the cabin. During this period, the second steel wire rope reel does not move;

[0021] When the old belt completely exits the cabin, disconnect the connection between the middle piece and the right piece of the two-way flange or two-way electromagnetic clutch, then pull out a part of the new belt on the new belt reel, and finally connect the connection hole at one end of the new belt to the first hook or the second hook on the steel wire rope, so that the steel wire rope can pull the new belt to move;

[0022] After the new belt is connected to the steel wire rope, connect the middle plate and the left plate of the two-way flange or the two-way electromagnetic clutch, that is, connect the flange or the electromagnetic clutch plate connected to the second central shaft to the flange or the left electromagnetic clutch plate connected to the second steel wire rope reel. After starting the second reel driver, the second central shaft can drive the second steel wire rope reel to rotate, thereby pulling the steel wire rope. The steel wire rope is connected to the new belt, and then the new belt can be introduced into the cabin.

[0023] After the new belt completely enters the cabin, cut off the position where the steel wire rope is connected to the new belt, and then perform subsequent processing.

[0024] Then start the second reel driver, and recover and reset the steel wire rope through the first central shaft and the first steel wire rope reel. Description of the Drawings
