Description

Technical Field

[0001] The utility model belongs to the technical field of the production of wind turbine nacelle covers, and particularly relates to a nacelle engraving and grinding machine with a dust removal function. Background Art

[0002] The structures of offshore wind turbine nacelle covers mostly adopt fiberglass reinforced plastics; fiberglass reinforced plastics have the advantages of light weight, high strength, corrosion resistance, good insulation, and low elastic modulus; due to the variable curvature of the structure form of offshore wind turbine nacelle covers, the hand lay-up method is mostly used for the production of fiberglass reinforced plastic shells; however, during the production and processing of fiberglass reinforced plastic nacelle covers by the hand lay-up method, it is often difficult to ensure the surface roughness of the nacelle cover shell, which requires the later use of a grinding machine to grind the nacelle cover shell. However, during the engraving and grinding process of the nacelle cover shell, if the ground fiberglass dust is not cleaned in time, it will adsorb on the surface of the nacelle cover structure, greatly affecting the production quality of the wind turbine nacelle cover; in the past production engraving and grinding process, workers mostly used a grinding machine to grind the nacelle cover shell first, and then used a compressed gas pipeline to blow and clean the grinding surface, which affected the production and processing efficiency of workers. Therefore, it is very necessary to provide a nacelle engraving and grinding machine with a dust removal function. Summary of the Invention

[0003] In order to solve the problem of dust scattering during the grinding of the engraving and grinding machine, the utility model provides a nacelle engraving and grinding machine with a dust removal function. The utility model effectively integrates the grinding and dust removal of the wind turbine nacelle cover, not only improving the production grinding efficiency of the nacelle cover, reducing the production labor intensity of workers, but also effectively sucking the dust generated when the fiberglass is ground.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] The utility model provides a nacelle engraving and grinding machine with a dust removal function, including an engraving and grinding machine body, a housing, a dust suction cavity, and a dust suction box. A dust suction cavity is arranged at the grinding head end of the engraving and grinding machine body, a housing is arranged on one side of the dust suction cavity, the grinding head is located in the housing, a hose is connected between the dust suction cavity and the housing and the dust suction cavity and the housing are fixed by a support arm, and the dust suction cavity is also connected to the dust suction box through a dust suction pipe. The housing is used to block the diffusion of dust generated after the grinding head of the engraving and grinding machine body grinds the surface of an object.

[0006] Further, the dust suction cavity includes a housing and a cover plate. The housing is located at the grinding head end of the engraving and grinding machine body, and the cover plate is connected to the opening of the housing. The cover plate is used to close the dust suction cavity to collect dust therein and enter the dust suction box through the dust suction pipe.

[0007] Further, one end of the housing is connected to a dust collection joint. The end of the dust collection joint away from the housing is sequentially connected to a flexible joint and a suction pipe. The end of the suction pipe away from the flexible joint is connected to a suction box.

[0008] Further, a rotating rod is fixedly arranged on the housing. Fixed rods are connected to both sides of the cover housing. One end of the support arm is rotatably arranged on the rotating rod, and the other end is fixedly arranged on the fixed rod. The rotating rod serves as the fulcrum for the rotation of the support arm, enabling the up-and-down adjustment of the cover housing.

[0009] Further, a limiting rod is arranged on one side of the dust suction cavity close to the cover housing. The limiting rod limits the support arm. The purpose of the limiting rod is to prevent the support arm from swinging downward, so that there is a gap between the cover housing and the grinding head without contact.

[0010] Further, the cover housing includes an observation cover and a dust-proof shell. The dust-proof shell is connected to the opening of the observation cover. The function of the observation cover is to facilitate observing the grinding degree of the surface of the object to be ground when the grinding head is working.

[0011] Further, connecting cross plates I are arranged at the bottoms of both sides inside the dust-proof shell. The bottom of the cross plate I is fixedly connected to the cross plate II. Ball bearings are arranged through the cross plate I and the cross plate II. The bottom of the dust-proof shell is fixedly connected to a brush frame. The ball bearings can enable the cover housing to move along the surface of the object without generating scratches, so that the dust generated after grinding is concentrated in the cover housing as much as possible. The brush frame can be used to clean the dust after grinding, and can also further seal the gap between the edge of the cover housing and the surface of the object to be ground to prevent the dust from spreading.

[0012] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] 1. The staff holds the engraving machine body and grinds the object to be ground. The dust generated during this process is shrouded by the cover housing. The shrouded dust is affected by the suction of the suction box, enters the dust suction cavity through the hose connected to the cover housing, and then enters the suction box from the dust suction cavity, solving the problem of dust dispersion during the grinding process.

[0014] 2. The present utility model rotates the support arm through operation to change the position of the cover housing connected to the support arm. When grinding, the cover housing is buckled above the grinding head, so that the grinding head is semi-surrounded and shrouded, effectively blocking the dust generated during the grinding of the grinding head.

[0015] 3. The limit rod provided at one end of the dust suction cavity is used to limit the support arm, preventing the connected cover from contacting the grinding head and causing wear. During operation, dust enters the dust suction cavity through the hose connected between the cover and the dust suction cavity. Due to dust settlement, a dust collection joint is provided at the bottom of the dust suction cavity, and the dust collection joint can be disassembled to clean the blocked dust in a timely manner. At the same time, the flexible joint at the bottom of the dust collection joint and the pipe clamp act on the dust suction pipe to prevent external air from entering and affecting the dust suction cavity.

[0036] One end of the fixed rod 182 is provided with a fixed limit block, the middle part is a cylinder, and two wing plates are provided on both sides of the cylinder. The other end of the fixed rod 182 is rotatably connected with a nut 181. A through hole matching the fixed rod 182 is formed in the dust-proof housing 12. The fixed rod 182 passes through the through hole and is connected with the support arm 18. Due to the limitation of the wing plates on both sides of the cylinder, the fixed rod 182 limits and fixes the support arm 18 and the cover 1.

[0037] The limit block can be circular, square, etc., and the thickness is mostly thin. As long as it can play a fixing role. The above wing plates can be fixedly welded or inserted and fixed, not limited to one way, as long as it can play a fixing role.

[0038] As an implementable manner, a limit rod 23 is arranged on one side of the dust suction cavity 2 close to the cover 1, and the limit rod 23 limits the support arm 18.

[0039] In this embodiment, both ends of the limit rod 23 protrude from the left and right sides of the dust suction cavity 2, and the extended parts are used to block the downward rotation of the support arm 18.

[0040] The limit rod 23 is fixed at the horizontal middle position of the cover plate 22 of the dust suction cavity 2, and is fixed to the housing 21 by screws passing through the limit rod 23 and the cover plate 22.

[0047] Working principle of this utility model:

[0048] Before the staff starts the grinder body 3 to grind the cabin cover and other objects, they first rotate the support arm 18 to buckle the cover 1 above the grinding head of the grinder body 3. When the staff is using the grinder body 3 to grind, they can lift the grinder body 3 and change the grinding area after the grinding work is completed and the dust is sucked clean. When moving during the grinding process, a ball 16 is provided between the horizontal plate 13 and the horizontal plate 2 14 fixedly connected at the bottom of the dust cover 12. The ball 16 can be moved between the cabin cover and other materials. The surface of the material can be rolled without leaving any traces, so when the grinding area is not completed and the dust is not sucked out, the grinder body 3 cannot be lifted to avoid dust diffusion. The cover shell 1 above the grinding head of the grinder body 3 is moved closely in the grinding area by relying on the ball 16. At the same time, a brush frame 15 is bonded to the bottom of the dustproof shell 12 to clean the dust that has not been sucked out during movement, so that the dust can be concentrated for secondary suction. The observation cover 11 on the top of the dustproof shell 12 is convenient for the operator to observe the grinding degree when grinding the object.

[0049] The dust generated by the staff during the grinding process of using the grinder body 3 enters the hose 19 through the cover 1, enters the dust collection chamber 2 through the hose 19, then enters the dust collection pipe 26 through the dust collection chamber 2, and enters the dust collection box 4 through the dust collection pipe 26. At the same time, the dust collection joint 25 at the bottom of the dust collection chamber 2 can be removed to clean the dust blocked inside in time.

[0050] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent shall be included within the scope of the patent application of the present invention.
