Technical Field

[0001] The utility model relates to the field of wind power tower component manufacturing technology, specifically a wind power tower frame forming device. Background Technology

[0002] In the manufacturing process of wind turbine towers, the frame is a key load-bearing component, and its forming quality directly affects the overall performance and stability of the tower. The steel plate of the frame is generally small in volume and weight, thick, elliptical in shape, with a large bending angle and an unfixed bending diameter. Existing plate rolling machines have difficulty achieving the designed bending effect in the bending process of the frame in the wind power industry, taking the wind turbine tower frame forming device as an example.

[0003] Some wind power tower door frame forming devices are inconvenient for limiting and fixing door frame templates of different sizes, and the main body of the device is also inconvenient for placing, moving and adjusting the hydraulic jacking device, which makes it difficult to squeeze and bend the door frame templates at different positions. Therefore, a wind power tower door frame forming device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wind power tower door frame forming device to solve the problem that some wind power tower door frame forming devices are inconvenient to limit and fix door frame templates of different sizes, and the main body of the device is inconvenient to place and move the hydraulic jacking device, which makes it difficult to squeeze and bend the door frame templates at different positions.

[0005] To achieve the above objectives, the utility model provides the following technical solution:

[0006] A wind power tower door frame forming device includes a base plate, channel steel, and an upper sealing plate. The upper sealing plate has four sliding grooves for the support plate inside, and two bolt grooves symmetrically arranged on both sides of each sliding groove. A lamp holder and a baffle are welded and fixed to the top of the upper sealing plate. A reinforcing rib is welded and fixed to the end of the baffle away from the sliding groove, and the reinforcing rib is welded and fixed to the top of the upper sealing plate. An M-shaped bracket is placed against the baffle near the sliding groove. A partition is welded and fixed inside the M-shaped bracket, and a magnet is welded and fixed inside the partition. A hydraulic jacking device is placed inside the M-shaped bracket, and an iron sheet is welded and fixed to the end of the hydraulic jacking device near the partition. A door frame strip is placed on the top of the upper sealing plate. A T-shaped support plate slides inside the sliding groove. A positioning bolt is threaded inside the T-shaped support plate, and a washer is fitted on the outside of the positioning bolt. A hexagonal threaded sleeve is threaded onto the positioning bolt.

[0007] Preferably, the bottom of the upper sealing plate is provided with a base plate, and the top of the base plate and the bottom of the upper sealing plate are fixed together by welding with channel steel.

[0008] Preferably, the magnet block and the iron sheet are magnetically attracted and in contact.

[0009] Preferably, the positioning bolt is located inside the bolt groove, and the bottom end of the washer is in contact with the top end of the upper sealing plate.

[0010] Preferably, the hydraulic inlet and hydraulic outlet at the top of the hydraulic jack are connected to an external hydraulic operating system.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] In this invention, a plate rolling machine is used for pre-rolling and bending of the door frame. Then, workers use a door frame template to draw the outline of the door frame on the base. The pre-rolled and bent door frame template is placed between two hydraulic jacking devices, and its position is adjusted to basically coincide with the outline of the door frame. It is then fixed with a T-shaped support plate. When the hydraulic jacking devices start working, they press and bend the door frame template until the preset arc is formed. The template is then used for inspection. The device can fix door frames of different sizes of wind turbine towers and can also easily change the position of the door frame during processing, thereby improving processing efficiency. The light frame welded on the base also provides illumination for the position during nighttime processing, making it convenient for workers to operate. This device is easy to operate, greatly reducing the technical requirements for operators and improving the forming quality and production efficiency of the door frame. Through the above settings, the main body of the device can limit and fix door frame templates of different sizes, and the main body of the device can easily place, move, and adjust the hydraulic jacking devices, allowing for extrusion and bending of the door frame template at different positions.

A reinforcing rib 8 is welded and fixed to the end of the baffle 7 away from the sliding grooves 5, and the reinforcing rib 8 is welded and fixed to the top of the upper sealing plate 3. An M-shaped bracket 9 is placed against the baffle 7 near the sliding grooves 5, and the M-shaped bracket 9 is welded and fixed inside. A partition 10 is provided, and a magnet block 11 is welded and fixed inside the partition 10. A hydraulic jacking device 12 is placed inside the M-shaped bracket 9. An iron sheet 13 is welded and fixed to one end of the hydraulic jacking device 12 near the partition 10. A door frame strip 14 is placed on the top of the upper sealing plate 3. A T-shaped horse plate 15 is slidably provided inside the horse plate groove 5. A positioning bolt 16 is threadedly assembled inside the T-shaped horse plate 15. A washer 17 is fitted on the outside of the positioning bolt 16. A hexagonal threaded sleeve 18 is threadedly assembled on the positioning bolt 16.

[0030] The bottom of the upper sealing plate 3 is provided with a base plate 1. The top of the base plate 1 and the bottom of the upper sealing plate 3 are fixed by welding with channel steel 2. Through the above arrangement, the base plate 1, channel steel 2 and upper sealing plate 3 are all made of high-strength steel, which together form a processing support platform.

[0031] The magnet 11 and the iron sheet 13 are magnetically attracted and in contact. This arrangement is used to assist in the placement and limiting of the hydraulic jacking device 12.

[0032] The positioning bolt 16 is located inside the bolt groove 4, and the bottom end of the washer 17 is in contact with the top end of the upper sealing plate 3. Through the above arrangement, the bolt groove 4 cooperates with the mounting plate groove 5 to form an adjustable installation positioning of the T-shaped mounting plate 15.

[0033] The hydraulic jacking device 12 has a hydraulic inlet and a hydraulic outlet at its top that are connected to an external hydraulic operating system. With the above configuration, the hydraulic jacking device 12 serves as a power drive component for extruding and bending the door frame strip 14.

[0034] Work process: The utility model provides a wind power generation tower door frame forming device. Through the bolt groove 4, the slab groove 5, the T-shaped slab 15, the positioning bolt 16, the washer 17 and the hexagonal screw sleeve 18, the main body of the device can limit and fix door frame strips 14 of different sizes. The main body of the device is convenient for placing and moving the hydraulic jacking device 12, and can extrude and bend the door frame strips 14 at different positions.

[0035] The lamp holder 6 and the hydraulic jack 12 installed inside the device are controlled by an external PLC controller, and the hydraulic operating system installed outside the lamp holder 6 and the hydraulic jack 12 are powered and controlled by an external power supply device.

[0036] The base plate 1, channel steel 2, and upper sealing plate 3 together serve as a processing support platform, all made of high-strength steel to ensure the stability and durability of the device. The upper sealing plate 3 has bolt grooves 4 and horse plate grooves 5 inside, which can be adjusted according to the size of different door frame templates 14 to fix the door frame templates 14.

The M-type bracket 9 can be moved along the baffles 7 and its position can be adjusted according to the actual situation of the door frame templates 14 to ensure the stability of the hydraulic jacking device 12 during operation.

[0037] First, the cut and polished door frame template 14 is pre-bent using a plate rolling machine. Then, the workers compare the curvature parameters of the door frame template 14 with the curvature parameters required for the finished product. The outline parameter lines of the door frame template 14 required for the finished product are drawn on the top of the upper sealing plate 3. The pre-bent door frame template 14 is placed between two hydraulic jacking devices 12 placed inside the M-shaped bracket 9. The position of the door frame template 14 is adjusted to basically coincide with the outline parameter lines of the door frame. The door frame template 14 is limited and fixed using a T-shaped support plate 15. When the hydraulic jacking device 12 starts working, it drives the moving pressure head of the hydraulic jacking device 12 to squeeze and bend the door frame template 14. If necessary, flame heating can be used to assist in applying force until the preset curvature is pressed out. The finished door frame template 14 prepared in advance is compared and inspected until it passes the inspection.

[0038] The device is simple and convenient to operate, improves the manufacturer's processing capacity, makes up for the insufficient processing capacity of the plate rolling machine, and reduces equipment procurement costs.
