Description

Technical Field

[0001] The utility model relates to the technical field of rudder and propeller maintenance, in particular to a rudder and propeller maintenance platform. Background Art

[0002] The rudder paddle is a fixed device, usually installed on the left side of the hull of the dragon boat's stern cabin. Its total length is 2.50 meters, of which the blade is 75 centimeters long, the leading edge of the blade is 20 centimeters wide, the upper end is 16 centimeters wide, and it has an arc-shaped bevel extending 15 centimeters, with an allowable error of ±3 mm. The thickness of the blade edge is usually between 0.7 and 1 centimeter. The diameter of the paddle shaft is 5 centimeters at the bottom and 3.5 centimeters at the top, while the length of the paddle handle is 15 centimeters and the diameter is 3.5 centimeters. The rudder paddle needs to be maintained and repaired frequently when in use.

[0003] A rudder propeller repair test platform disclosed in announcement number CN215707019U can simulate the state of the propeller when it is working, simulate the working conditions of the rudder propeller under various working conditions, detect the operating conditions of the internal components of the rudder propeller, detect the resonance point of the rudder propeller, and provide a basis for avoiding the resonance point during the normal operation of the rudder propeller. It is easy to use and operate.

[0004] However, this kind of rudder propeller repair test platform has the following disadvantages:

[0005] When maintaining and repairing the rudder propeller, due to its heavy weight, it is necessary to use a lifting structure to lift the rudder propeller for maintenance, and there is a lack of fracture protection for the mechanism for lifting the rudder propeller, which causes the rudder propeller to fall directly and break, causing losses;

[0006] When the rudder propeller is lifted and inspected, the lack of fixation of the rudder propeller causes the rudder propeller to shake, affecting the inspection and maintenance. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a rudder propeller maintenance platform, and solve the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0009] A steering propeller maintenance platform comprises: a fixing rod, a fixing frame is arranged on the surface of the fixing rod, an electric hoist body for lifting the steering propeller is arranged at the bottom of the fixing frame, a protective component for preventing breakage is arranged axially symmetrically at the bottom of the electric hoist body, support rods are fixedly connected to both ends of the fixing rod in an axially symmetrical manner, and a positioning component for fixing the steering propeller is arranged in the middle of the side of the support rod.

[0010] Optionally, the protective component includes a frame axially symmetrically arranged at the bottom of the electric hoist body, a groove is provided at the inner bottom of the frame, and a fixing plate is provided on one side of the groove, a roller is provided at the top of the fixing plate, a protective rope is wrapped around the surface of the roller, a counterweight block for adding counterweight is provided at one end of the protective rope, and a ring is provided at the other end of the protective rope.

[0011] Optionally, the positioning assembly includes a positioning plate arranged in the middle of the side of the support rod, the surface of the positioning plate is provided with a threaded screw for adjusting the tightness, one end of the threaded screw is rotatably connected to a clamping plate for fixing the rudder propeller, and the other end of the threaded screw is provided with a swivel for driving its forward and reverse rotation.

[0012] Optionally, a pull rope for lifting the rudder propeller is provided on the surface of the electric hoist body, one end of the pull rope is fixedly connected to the inside of the ring, a ring is provided on the surface of the pull rope and at the top of the ring, and a connecting rod is provided on one side of the ring.

[0013] Optionally, a slider is provided at one end of the connecting rod, and a slide plate is slidably connected to the surface of the slider, and the top of the slide plate is fixedly connected to the bottom of the electric hoist body. The design of the slide plate and the slider limits the pull rope on the electric hoist body to prevent it from swinging when lifting the steering propeller, thereby improving the lifting stability of the steering propeller.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] 1. The steering propeller maintenance platform is provided with a protective component. When the steering propeller is being repaired, the steering propeller is fixed at the bottom end of the pull rope, and the electric hoist body is connected to an external power supply, so that the steering propeller is lifted by the pull rope, and then the steering propeller is raised to the maintenance height. At this time, one end of the pull rope is fixed by the ring, and protective ropes are provided on both sides of the ring. When the ring driven by the steering propeller breaks and falls from one end of the pull rope, the ring will be driven to pull the protective rope, so that the protective rope moves on the roller. Since a counterweight block is provided at one end of the protective rope, it is affected by the counterweight block to offset the weight of the steering propeller itself, so that the steering propeller is pulled by the counterweight block and the protective rope, so that it is suspended in the air to avoid direct falling and damage, thereby improving the protection during the maintenance of the lifting steering propeller.

[0016] 2. The steering propeller inspection platform, through the setting of the positioning component, when the steering propeller is lifted to the inspection height, the swivel can be rotated to make the swivel drive the threaded screw to rotate, and drive the clamping plate to move in the direction of the steering propeller until the surface of the clamping plate fits the surface of the steering propeller. As the number of rotations of the threaded screw increases, the steering propeller can be firmly fixed between the clamping plates, thereby preventing the steering propeller from shaking during inspection, thereby improving the stability of the steering propeller during inspection.

[0031] Embodiment 2:

[0032] See also Figure 4 As shown, in this embodiment, the positioning assembly 6 includes a positioning plate 61 arranged in the middle of the side of the support rod 5, and a threaded screw 62 for adjusting the tightness is arranged on the surface of the positioning plate 61, one end of the threaded screw 62 is rotatably connected to a clamping plate 63 for fixing the steering propeller, and the other end of the threaded screw 62 is provided with a swivel 64 for driving the steering propeller to rotate forward and reverse.

[0033] One aspect of the application of this embodiment is that the working steps of the device are as follows:

[0034] Step 1: When inspecting the steering oar, fix the steering oar at the bottom end of the pull rope 7, and connect the electric hoist body 3 to the external power supply so that the steering oar is lifted through the pull rope 7, and then the steering oar is raised to the inspection height. At this time, one end of the pull rope 7 is fixed by the ring 443, and at the same time, protection ropes 441 are arranged on both sides of the ring 443. When the steering oar drives the ring 443 to break and fall from one end of the pull rope 7, the ring 443 will drive the ring 443 to pull the protection rope 441, so that the protection rope 441 moves on the roller 44. Since a counterweight block 442 is arranged at one end of the protection rope 441, it is affected by the counterweight block 442, which can offset the weight of the steering oar itself, so that the steering oar is pulled by the counterweight block 442 and the protection rope 441, so that it is suspended in the air to avoid direct falling and damage.

[0035] Step 2: When the steering propeller is lifted to the inspection height, the swivel 64 can be rotated to drive the screw rod 62 to rotate and drive the clamping plate 63 to move toward the steering propeller until the surface of the clamping plate 63 is attached to the surface of the steering propeller. As the number of turns of the screw rod 62 increases, the steering propeller can be firmly fixed between the clamping plates 63.
