Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutter suction dredger equipment, in particular to a cutter maintenance sliding platform. BACKGROUND

[0002] Cutter suction dredgers are widely used in port, channel dredging and reclamation engineering. The cutter, as the main tooling equipment on the dredger, works mainly by rotating the cutter head at the front end to loosen the soil or debris on the seabed, and then collecting and processing them through the pipeline.

[0003] The structure of the cutter head includes a cutter ring, a plurality of cutter arms are arranged on the cutter ring, and a plurality of cutter teeth are arranged on each cutter arm. Due to the harsh construction conditions of the cutter suction dredger, the cutter teeth installed on the cutter head will be excessively worn after a period of work. Therefore, the workers need to frequently maintain the cutter head, regularly check and replace the excessively worn cutter teeth. Workers usually use a crane to replace the entire cutter head, but it is not convenient to use a crane for the replacement of the cutter teeth, and it is more convenient and reasonable for workers to directly stand on the cutter maintenance platform to replace the cutter teeth on the suspended cutter head. The cutter maintenance platform is a platform structure located at the stern of the cutter suction dredger for maintaining the cutter head. Figure 1 With Figure 2 As shown in the prior art, the cutter maintenance platform 100 on some existing dredgers has a certain distance designed between the turning and the cutter head 101. When the worker stands on the cutter maintenance platform 100, the arm cannot reach the cutter head 101, so the worker cannot replace the cutter teeth and cannot complete the daily maintenance work of the cutter head 101.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] like Figure 3 As shown in the figure, a preferred embodiment of the present invention provides a cutter head maintenance sliding platform, comprising a sliding platform body 1, at least two guide rails 2, sliders 3, a pulley assembly 4, and a traction rope (not specifically shown in the figure). The sliding platform body 1 is provided with at least two eye rings 121, and the at least two eye rings 121 protrude from the left and right sides of the sliding platform body 1, respectively. The at least two guide rails 2 are installed parallel and spaced apart on the maintenance platform 5 of the hull, with the front end of the guide rail 2 facing the cutter head. Each guide rail 2 corresponds to at least one slider 3, and the slider 3 is installed below the sliding platform body 1, with each slider 3 able to cooperate with and be guided by its corresponding guide rail 2. The pulley assembly 4 includes two front guide pulleys 41 and at least one rear guide pulley 42, with both front guide pulleys 41 installed on the maintenance platform. On the platform 5, and located on the left front and right front sides of the sliding platform body 1 respectively, each of the front guide pulleys 41 has an eye ring 121 directly behind it. At least one rear guide pulley 42 is installed on the maintenance platform 5 and located on the rear side of the sliding platform body 1, with an eye ring 121 directly in front of each of the rear guide pulleys 42. One end of the traction rope is used to connect to the hoisting device (not specifically shown in the figure), and the other end of the traction rope can be wrapped around the front guide pulley 41 and connected to the eye ring 121 corresponding to the front guide pulley 41 to pull the sliding platform body 1 forward. The other end of the traction rope can also be wrapped around the rear guide pulley 42 and connected to the eye ring 121 corresponding to the rear guide pulley 42 to pull the sliding platform body 1 backward.

[0032] Based on the above embodiment of the reamer maintenance sliding platform, by laying the guide rail 2 on the maintenance platform 5 of the dredger, and placing the sliding platform body 1 with the sliding block 3 installed at the bottom on the guide rail 2, the sliding block 3 can cooperate with the guide rail 2 for guidance, and the front guide pulley 41 and the rear guide pulley 42 are arranged on the maintenance platform 5, when the workers need to replace the reamer teeth, the traction rope is wound on the front guide pulley 41, one end of the traction rope is connected to the hoisting device, and the other end is connected to the eye ring 121 on the sliding platform body 1 corresponding to the front guide pulley 41, so that the hoisting device can pull up the traction rope upward, so that the sliding platform body 1 slides forward to the lower side of the reamer head; after the workers complete the replacement of the reamer teeth, the traction rope is wound on the rear guide pulley 42, one end of the traction rope is connected to the hoisting device, and the other end is connected to the eye ring 121 on the sliding platform body 1 corresponding to the rear guide pulley 42, so that the hoisting device can pull up the traction rope upward, so that the sliding platform body 1 slides back to the initial position; the reamer maintenance sliding platform enables the workers to reach the reamer head and the reamer teeth, and facilitates the workers to complete the daily maintenance work of the reamer head and the replacement of the reamer teeth.

[0033] In some preferred embodiments, the number of the rear guide pulleys 42 is two, and the two rear guide pulleys 42 are arranged at the rear side of the sliding platform body 1. The arrangement of the two rear guide pulleys 42 can balance and facilitate the sliding of the sliding platform body 1 backward.

[0034] Preferably, the two rear guide pulleys 42 are arranged at the rear side of the sliding platform body 1, and the number of the eye rings 121 is four, wherein two of the eye rings 121 protrude from the left and right sides of the sliding platform body 1 and correspond to the two front guide pulleys 41 respectively, and the other two eye rings 121 are arranged at the rear side of the sliding platform body 1 and correspond to the two rear guide pulleys 42 respectively. When the sliding platform body 1 is slid forward, the traction rope is sleeved on the eye rings 121 protruding from the left and right sides of the sliding platform body 1, the middle section of the traction rope is wound on the front guide pulley 41, and the other end of the traction rope is pulled upward by the hoisting device; when the sliding platform body 1 is slid backward, the traction rope is sleeved on the eye rings 121 at the rear side of the sliding platform body 1, the middle section of the traction rope is wound on the rear guide pulley 42, and the other end of the traction rope is pulled upward by the hoisting device.
