Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of marine diesel engines, and particularly relates to a carrier bracket for a marine diesel engine. Background Technique
[0002] Diesel engines are a widely used type of internal combustion engine. By compressing a mixture of diesel and air, their temperature and pressure are increased, thereby triggering the spontaneous combustion of diesel. They are mainly used as power sources for power generation, vehicles (such as trucks, buses, certain types of trains, and ships), and some fixed applications (such as agricultural equipment and construction machinery). Marine diesel engines are diesel engines specifically designed and manufactured for ships, and with their characteristics such as high efficiency, reliability, and strong adaptability, they occupy an important position in the field of ship propulsion power. Carrier brackets are used during the transportation and installation of marine diesel engines.
[0003] Common carrier brackets for marine diesel engines are usually composed of components such as a seat plate, lifting lugs, columns, trays, and crossbars. First, the marine diesel engine is placed on the tray of the seat plate, and lifting operations can be carried out through the lifting lugs installed around the seat plate, while the lifting lugs, columns, and crossbars can provide support for the seat plate.
[0004] Traditional carrier brackets for marine diesel engines have a limited load-bearing capacity for marine diesel engines. When a heavier marine diesel engine is placed on the carrier bracket, it will cause the carrier bracket to break, resulting in damage to the marine diesel engine and other phenomena. Some carrier brackets for marine diesel engines attempt to increase the load-bearing capacity for placing diesel engines by replacing materials or thickening the trays. However, this method still leads to an increase in the usage cost of the carrier bracket because materials with stronger load-bearing capacities are more expensive. For this reason, a carrier bracket for a marine diesel engine is proposed. Content of the Utility Model
[0005] (I) Technical Problems to be Solved
[0006] In view of the deficiencies of the prior art, the utility model provides a carrier bracket for a marine diesel engine to solve the technical problem that replacing materials to increase the load-bearing capacity will result in an increase in usage cost.
[0007] (II) Technical Solutions
[0008] To achieve the above object, the utility model provides the following technical solutions: A carrier bracket for a marine diesel engine, comprising:
[0009] A top plate, and a bottom plate disposed directly below the bottom of the top plate, and rib plates are provided between the top plate and the bottom plate;
[0010] A web plate, disposed on the back of the top plate, and connected to the back of the top plate, the bottom plate, and the rib plates;
[0011] The lifting lug plate is arranged at the upper outer side of the rib plate, and bolt holes are evenly formed at the top of the top plate. By directly connecting the top plate with the bottom plane of the diesel engine's frame, bolt holes are arranged on the top plate. The hole pitch of the bolt holes is consistent with the hole pitch of the frame's bottom feet holes, and the bolt holes are designed as waist-shaped holes to ensure that the top plate can be smoothly connected with the bottom plane of the frame. The bottom plate is located at the lowermost part of the carrier bracket and is the position in direct contact with the ground. The width of the bottom plate needs to be greater than the width of the top plate to ensure the stability and reliability of the carrier bracket when carrying the diesel engine. The rib plates are arranged in the regional space enclosed by the top plate, the bottom plate, and the web plate, playing a role in strengthening the overall structural strength of the carrier bracket. The height of the web plate needs to be greater than the height of the diesel engine's oil pan, so as to ensure that the carried diesel engine does not touch the ground. The lifting lug plate is welded on the two outermost rib plates, facilitating the use of a sling to transfer the carrier bracket. It can be used as a platform tool for installing the machine in the manufacturing workshop and also as a bracket for carrying marine diesel engines. The structure is simple, with few matching parts and convenient manufacturing.
[0012] Preferably, a connecting cylinder is vertically added to the inner cavity of the bolt hole, and a threaded ring is threadedly connected to the lower part of the outer surface of the connecting cylinder and is closely attached to the bottom of the top plate. The connecting cylinder can be connected with the bottom feet holes of the diesel engine's frame through the bolt holes, and the threaded ring can be rotated on the connecting cylinder and connected to the bottom of the top plate.
[0013] Preferably, a limiting head is added directly below the bottom of the connecting cylinder, and a guiding column is installed on the inner side surface of the limiting head and inserted into the inner cavity of the connecting cylinder. The guiding column can be pulled out and pressed inward on the connecting cylinder through the limiting head.
[0014] Preferably, side grooves are vertically formed at the upper center positions on both sides of the connecting cylinder, and an inclined connecting rod is added to the inner cavity of the side grooves and is hinged to the guiding column. When the guiding column is pressed inward in the inner cavity of the connecting cylinder, it drives the inclined connecting rod to move and retracts into the inner part of the side groove, enabling the separation between the inclined connecting rod and the bottom feet holes of the diesel engine's frame.
[0015] Preferably, a convex head is installed at the center position of the inner end of the guiding column, a return spring is sleeved on the surface of the convex head, and a concave hole is formed at the center of the top of the inner cavity of the connecting cylinder and corresponds to the convex head. When the guiding column is pressed inward, the guiding column drives the convex head into the concave hole inside the connecting cylinder and compresses the return spring. After the pressure applied to the guiding column ends, it can be reset under the action of the return spring, and the inclined connecting rod extends outward from the side groove and is connected to the bottom feet holes of the diesel engine's frame. Compared with the method of using bolts for connection, the disassembly and assembly between this structure and the bottom feet holes of the diesel engine's frame are more convenient and rapid.
[0016] (III) Beneficial effects
[0017] Compared with the prior art, the utility model provides a carrier bracket for a marine diesel engine, which has the following beneficial effects:
[0018] For the carrier bracket of the marine diesel engine, the top plate is directly connected to the bottom plane of the engine frame of the diesel engine. Bolt holes are arranged on the top plate, and the hole spacing of the bolt holes is consistent with the hole spacing of the bottom feet of the frame. Moreover, the bolt holes are designed as waist-shaped holes to ensure that the top plate can be smoothly connected to the bottom plane of the frame. The bottom plate is located at the bottommost part of the carrier bracket and is the position directly in contact with the ground. The width of the bottom plate needs to be greater than the width of the top plate to ensure the stability and reliability of the carrier bracket when carrying the diesel engine. The rib plates are arranged in the area space enclosed by the top plate, the bottom plate, and the web plate, which plays a role in strengthening the overall structural strength of the carrier bracket and requires relatively low cost at the same time. The height of the web plate needs to be greater than the height of the oil sump of the diesel engine, so as to ensure that the carried diesel engine does not touch the ground. The lug plates are welded on the two outermost rib plates, which is convenient for using a sling to transfer the carrier bracket. It can be used as a platform tool for installing the engine in the manufacturing workshop and also as a bracket for carrying the marine diesel engine. The structure is simple, with few matching parts and is easy to manufacture. BRIEF DESCRIPTION OF THE DRAWINGS
