Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a bracket structure for installing a ship's tail shaft. Background Art

[0002] The stern shaft, also known as the tail shaft, is the last shaft in the shaft system. The tail shaft is generally installed from outside the cabin to inside the cabin. One end of the tail shaft needs to be aligned with the tail tube and slowly inserted. After the tail shaft passes through the tail tube, the propeller can be installed.

[0003] The existing tail shaft can be supported by a tooling during installation, making the installation of the tail shaft more convenient. For example, Chinese patent application number CN202320831720.7 discloses a ship stern shaft installation tooling, including a main stern shaft support mechanism, a secondary stern shaft support mechanism and a stern shaft support mechanism connecting shaft. The main stern shaft support mechanism is connected to the secondary stern shaft support mechanism through the stern shaft support mechanism connecting shaft. The main stern shaft support mechanism consists of a main mobile base, a main lifting mechanism, a main stern shaft support platform, a main micro laser rangefinder, a main engine, a main battery and an electric drum reel.

[0004] This tooling can connect the main support mechanism and the secondary support mechanism through a connecting shaft, so that the main and secondary support mechanisms can support the tail shaft at the same time. During the installation process, the tail shaft moves to one end. Since the distance between the main and secondary support mechanisms cannot be adjusted after the connection, the main support mechanism cannot move with the tail shaft, affecting the support effect.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a bracket structure for installing a ship's tail shaft, comprising a fixed plate 1 and a movable plate 2. Both sides of the upper surfaces of the fixed plate 1 and the movable plate 2 are longitudinally connected with columns 3, the upper ends of the corresponding two columns 3 are connected to the same supporting plate 4, and the upper ends of the other two columns 3 are connected to the same clamping plate 5. Pulleys are installed on the lower surfaces of the fixed plate 1 and the movable plate 2. Bolts 6 are threadedly connected to both sides of the clamping plate 5. The upper ends of the two bolts 6 are penetrated and connected with connecting plates 7. The two connecting plates 7 are connected to the sides facing each other with pressure rods 8. The surface of the bolts 6 is connected with a limiting block 9, and the upper surface of the limiting block 9 is fitted with the connecting plate 7. Screw holes 10 are penetrated and opened at the four corners of the upper surface of the fixed plate 1. The upper surfaces of the supporting plates 4 and the clamping plates 5 are consistent in height. The upper ends of the bolts 6 are hexagonal heads, and the direction of the movable plate 2 toward the fixed plate 1 is the direction of insertion of the tail shaft.

[0025] During operation, the fastener is screwed into the screw hole 10 so that the fastener is inserted into the reserved hole, thereby fixing the position of the fixing plate 1, placing the tail shaft on the supporting plate 4 and the clamping plate 5, and tightening the bolt 6 so that the bolt 6 drives the pressure rod 8 to move downward, and the pressure rod 8 is pressed tightly on the upper side of the tail shaft, so that the clamping plate 5 and the pressure rod 8 are clamped on the tail shaft, and the tail shaft is pushed toward the supporting plate 4 to insert the tail shaft into the tail pipe. When the tail shaft moves, the clamping plate 5, the pressure rod 8, and the movable plate 2 will move with the tail shaft, so that the clamping plate 5 continues to support the tail shaft. By setting the limit block 9, the connecting plate 7 can be limited to prevent the connecting plate 7 from shifting up and down.

[0026] See also Figure 1-4 The utility model provides a technical solution: a guide rod 11 is symmetrically connected to one side of the fixed plate 1 close to the movable plate 2, and the guide rod 11 penetrates the movable plate 2 and is slidably connected to the movable plate 2.

[0027] During operation, through the arrangement of the guide rod 11 , the guide rod 11 can play a guiding role when the movable plate 2 moves, so that the moving process of the movable plate 2 is more stable.

[0028] See also Figure 1-4 The utility model provides a technical solution: a plurality of grooves are provided on the upper surface of the support plate 4, and a roller 12 is rotatably connected inside the groove.

[0029] During operation, the roller shaft 12 is arranged so that when the tail shaft moves, the roller shaft 12 is driven to rotate, thereby reducing the friction between the upper surface of the support plate 4 and the tail shaft.

[0030] See also Figure 1-4 The utility model provides a technical solution: a connecting block 13 is connected to one end of the guide rod 11, an opening 14 is penetrated through the outer surface of the connecting block 13, a hole corresponding to the opening 14 is opened on the side of the fixed plate 1 close to the movable plate 2, and the opening 14 and the inner wall of the hole are both provided with threads.

[0031] During operation, by setting the connecting block 13 and the opening 14, fasteners can be screwed into the opening 14 and the hole, so as to fix the position of the connecting block 13 and the guide rod 11. The installation of the guide rod 11 is relatively convenient. After the subsequent installation of the tail shaft is completed, the guide rod 11 can be removed to facilitate the separate storage of the guide rod 11.

[0032] See also Figure 1-4 The utility model provides a technical solution: the outer surface of the pressure rod 8 is covered with rubber.

[0033] During operation, the friction between the pressure rod 8 and the tail shaft can be increased by setting the rubber, which is conducive to pressing the pressure rod 8 against the surface of the tail shaft.

[0034] See also Figure 1-4 The utility model provides a technical solution: the upper surfaces of the support plate 4 and the clamping plate 5 are both concave.

[0035] During operation, the concave surface is arranged so that the upper surfaces of the support plate 4 and the clamping plate 5 have a limiting effect, and the tail shaft is not easily offset after being placed on the upper surfaces of the support plate 4 and the clamping plate 5.

[0036] See also Figure 1-4 The utility model provides a technical solution: a fastening belt 15 is connected between the two pressure rods 8, and the fastening belt 15 is made of rubber.

[0037] During operation, when the pressure rod 8 presses the tail shaft, the tightening belt 15 will be in close contact with the upper surface of the tail shaft, thereby improving the pressing effect of the pressure rod 8. At the same time, the tightening belt 15 can limit the two pressure rods 8. When the bolt 6 is tightened, the pressure rod 8 and the connecting plate 7 are not prone to deflection.

[0038] In summary, screw the fastener into the screw hole 10 so that the fastener is inserted into the reserved hole, thereby fixing the position of the fixed plate 1, place the tail shaft on the support plate 4 and the clamping plate 5, and tighten the bolt 6 so that the bolt 6 drives the pressure rod 8 to move downward, and the pressure rod 8 is pressed on the upper side of the tail shaft, so that the clamping plate 5 and the pressure rod 8 are clamped on the tail shaft, and the tail shaft is pushed in the direction of the support plate 4 to insert the tail shaft into the tail pipe. When the tail shaft moves, the clamping plate 5, the pressure rod 8, and the movable plate 2 will move with the tail shaft, so that the clamping plate 5 continues to support the tail shaft, and when the movable plate 2 moves, the guide rod 11 can play a guiding role, so that the movement process of the movable plate 2 is more stable.
