Description

Technical Field

[0001] This utility model belongs to the field of welding technology in wind turbine production, and specifically relates to a welding device for wind turbine production. Background Technology

[0002] A fan drives the gas to rotate through a high-speed rotating impeller. The gas gains energy under the action of the impeller blades, and then enters the volute or diffuser, where some of the kinetic energy is converted into pressure energy, thereby increasing the gas pressure and realizing the gas transportation or pressurization. Since the fan casing is usually made of rolled and welded metal sheets, the welding of the fan is particularly important.

[0003] Problems with existing technology: Currently, existing welding equipment is prone to displacement at the longitudinal seam of the wind turbine casing due to the lack of a limiting structure, which affects the welding accuracy of the wind turbine casing. In addition, the existing welding equipment is not convenient for unloading the welded casing. Utility Model Content

[0004] The purpose of this utility model is to provide a welding device for wind turbine production. It can limit the longitudinal seam of the wind turbine shell by setting a limiting mechanism inside the shell. The limiting mechanism can work with the installation mechanism and support rod to abut and limit the longitudinal seam of the wind turbine shell, thereby preventing displacement during welding and improving welding accuracy. At the same time, the installation mechanism also facilitates material unloading.

[0005] The specific technical solution adopted by this utility model is as follows: A welding apparatus for wind turbine production includes a frame, on the top of which a coarse adjustment assembly is fixedly mounted via a housing; The housing is equipped with a limiting mechanism inside, and a mounting mechanism is provided at one end of the housing. The mounting mechanism is used to drive one end of the support rod to move vertically. The limiting mechanism includes a first cylinder fixedly installed inside the housing. The first cylinder is used to push the sliding plate to move linearly through a connecting member. The sliding plate drives the limiting plate to move synchronously, so that the limiting plate pushes the fan housing to abut against the support rod.

[0006] The coarse adjustment component is used to drive the fine adjustment component to move longitudinally, the fine adjustment component is used to drive the welding component to move laterally and vertically, and the fine adjustment component is used to drive the welding component to move linearly along the top of the fan casing.

[0007] The first cylinder and the sliding plate are arranged in six sets, and are arranged in a mirror image on both sides of the inside of the housing.

[0008] The sliding plate and the connecting piece are fixedly installed. A guide rail is fixedly installed on the top of the sliding plate so that the sliding plate and the connecting frame are slidably installed. The connecting frame is fixedly installed on the bottom of the housing.

[0009] The sliding plate and the limiting plate are correspondingly set and fixedly installed, and the bottom of the limiting plate protrudes from the bottom of the sliding plate, and the cross section of the limiting plate is a right trapezoid.

[0010] The mounting mechanism includes a mounting bracket fixedly mounted on one end of the housing. A second cylinder is fixedly mounted on one side of the mounting bracket. The second cylinder is used to drive the rack and pinion to mesh and transmit power, so that the gear drives the fixed bracket to move in a fan shape, causing one end of the support rod to separate from the mounting mechanism, and the other end of the support rod to be hinged to the frame.

[0011] A lifting cylinder is fixedly installed at the bottom of the fixed frame. The lifting cylinder is used to push the slide to drive one end of the support rod to move vertically.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes a first cylinder fixedly installed inside the housing and a connecting frame fixedly installed at the bottom of the housing. The first cylinder can push the connecting piece to drive the sliding plate to move linearly at the bottom of the connecting frame, causing the sliding plate to drive the limiting plate to move synchronously. Therefore, the installation mechanism sends the fan housing to the bottom of the limiting mechanism through the support rod. Thus, the movement of the limiting plate can cooperate with the support rod to clamp and fix the splice of the fan housing, thereby ensuring that the welding components will not shift when welding the splice of the fan housing, thereby improving the welding quality.

[0013] This utility model features a mounting bracket at one end of the housing, with a second cylinder fixedly mounted on one side of the mounting bracket. When the second cylinder is activated, it can push the rack to rotate the gear, causing the gear to drive the fixed bracket in a fan-shaped motion. At the same time, the activation of the lifting cylinder causes the slide to move down, thereby allowing the support rod to move out of the mounting mechanism. This facilitates the easy unloading of the fan housing after the support rod surface has been welded. Attached Figure Description

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-4 As shown, a welding device for wind turbine production includes a frame 1, and a coarse adjustment assembly 3 is fixedly installed on the top of the frame 1 through a housing 2. The housing 2 is equipped with a limit mechanism 6 inside, and a mounting mechanism 7 is provided at one end of the housing 2. The mounting mechanism 7 is used to drive one end of the support rod 8 to move vertically. The limiting mechanism 6 includes a first cylinder 61 fixedly installed inside the housing 2. The first cylinder 61 is used to push the sliding plate 63 to move linearly through the connecting piece 62. The sliding plate 63 drives the limiting plate 65 to move synchronously, so that the limiting plate 65 pushes the fan housing 9 to abut against the support rod 8.

[0018] See attached document Figure 1 , Figure 2 and Figure 3 The coarse adjustment component 3 is used to drive the fine adjustment component 4 to move longitudinally. The fine adjustment component 4 is used to drive the welding component 5 to move laterally and vertically. The fine adjustment component 4 is used to drive the welding component 5 to move linearly along the top of the fan casing 9.

[0019] In the above embodiment, by activating the coarse adjustment component 3, the welding component 5 can move linearly along the splice seam of the fan housing 9, and the welding of the fan can be achieved by activating the welding component 5.

[0020] Furthermore, the fine adjustment component 4 uses manual fine-tuning to adjust the horizontal and vertical directions of the welding component 5, thereby further determining the welding position and improving the welding quality.

[0021] Please refer to the appendix again. Figure 2 and Figure 3The first cylinder 61 is located inside the housing 2, and the sliding plate 63 is located at the bottom of the housing 2. There are six sets of first cylinders 61 and sliding plates 63, which are arranged in a mirror image on both sides of the inside of the housing 2. At the same time, the six sets of first cylinders 61 and sliding plates 63 can be started and stopped independently. In this embodiment, it is preferable that the six sets of first cylinders 61 are started simultaneously, so that the fan housing 9 can be fixed on the top of the support rod 8. Of course, during the process of independently starting the first cylinder 61, the limiting mechanism 6 can be used to fix the fan housing 9 of different lengths.

[0022] According to the above structure, the sliding plate 63 is fixedly installed with the connecting piece 62, and the connecting piece 62 is hinged to the output shaft of the first cylinder 61. A guide rail is fixedly installed on the top of the sliding plate 63, so that the sliding plate 63 and the connecting frame 64 are slidably installed. The connecting frame 64 is fixedly installed on the bottom of the housing 2. Therefore, when the first cylinder 61 is started, the connecting piece 62 can push the sliding plate 63 to slide linearly at the bottom of the connecting frame 64.

[0023] It is worth noting that since the sliding plate 63 and the limiting plate 65 are correspondingly set and fixedly installed, and the bottom of the limiting plate 65 protrudes from the bottom of the sliding plate 63, and the cross section of the limiting plate 65 is a right trapezoid, when the limiting plate 65 moves under the action of the sliding plate 63, the bottom of the limiting plate 65 can push the splice of the fan housing 9 to be fixed to the top of the support rod 8.

[0024] See attached document Figure 1 , Figure 2 and Figure 4 The mounting mechanism 7 provided on one side of the housing 2 can drive the support rod 8 and the fan housing 9 to be adjusted to a horizontal state, thereby facilitating welding. After welding is completed, the support rod 8 can be separated from the mounting mechanism 7 by activating the mounting mechanism 7, which facilitates the unloading of the welded fan housing 9.

[0025] Specifically, a second cylinder 72 is fixedly installed on one side of the mounting bracket 71. The second cylinder 72 is used to drive the rack 73 to mesh with the gear 74, so that the gear 74 drives the fixed bracket 75 to move in a fan shape. Therefore, one end of the support rod 8 can be separated from the mounting mechanism 7, while the other end of the support rod 8 is hinged to the frame 1, so the support rod 8 will not fall off.

[0026] More specifically, a lifting cylinder 77 is also fixedly installed at the bottom of the fixed frame 75. The lifting cylinder 77 is used to push the slide 76 to drive one end of the support rod 8 to move vertically, thereby causing the support rod 8 to adjust the fan casing 9 to a horizontal state.

[0027] The working principle of this utility model is as follows: After the fan housing 9 is fitted onto the surface of the support rod 8, the first cylinder 61 is activated to push the connector 62 to drive the sliding plate 63 to move linearly. The sliding plate 63 drives the limiting plate 65 to abut against the splice seam of the fan housing 9. After the limiting plate 65 and the support rod 8 cooperate to fix the fan housing 9, the fine adjustment component 4 is manually adjusted to a suitable position. Then, the coarse adjustment component 3 and the welding component 5 are activated to weld the seam. After the welding is completed, the second cylinder 72 is activated to push the rack 73 to move vertically. The gear 74 drives the fixing frame 75 to move in a fan shape, so that one end of the support rod 8 is separated from the inside of the installation mechanism 7, which makes it easier to remove the fan housing 9 from the surface of the support rod 8.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
