Description

Technical Field

[0001] This invention relates to the field of wind power concrete tower technology, and in particular to a gluing device for concrete tower sections during mixed tower hoisting. Background Technology

[0002] With the further development and utilization of wind resources in my country, wind turbine generators are gradually developing towards higher power and higher altitudes. Traditional flexible all-steel tower technology for wind power is no longer sufficient to meet the requirements of wind turbine generator towers with high rigidity and large diameter. In recent years, with the promotion of prefabricated concrete technology in my country, the application of segmented prefabricated concrete towers in the field of wind power generation has become increasingly common. This effectively makes up for the shortcomings of low rigidity and small diameter of flexible steel towers. Generally speaking, concrete towers are divided into multiple sections along the height of the tower, and each section is basically composed of four prefabricated concrete segments spliced ​​on site.

[0003] The cylinder sections are stacked one on top of another, using a dry connection without grouting. Before adding a cylinder section, glue needs to be applied to the already installed section. Currently, workers climb ladders inside the cylinder section, carry glue buckets, and apply the glue to the cylinder section with a roller brush. However, standing on the ladder, they can only apply glue to a very small angle. For subsequent angles, they have to climb the ladder back onto the cylinder section to apply the glue. Applying glue to the entire cylinder section is time-consuming, laborious, and dangerous at height. Summary of the Invention

[0009] Furthermore, it also includes a first lug fixed to the middle of the lower end of the material bucket 1 and located in front of the gear pump 5. The first lug is hinged to a hinge bar 10 driven by the sliding member 9.2. The end of the hinge bar 10 is provided with a brush 11 for cleaning dust from the cylinder section.

[0010] Furthermore, the hinge 10 swings symmetrically left and right along the longitudinal section of the material barrel 1, and the swing angle of the hinge 10 is greater than or equal to 30 degrees and less than or equal to 45 degrees.

[0011] Furthermore, the upper end of the sliding member 9.2 is provided with a movable hole 9.2.1, and a sleeve 9.2.2 that allows the discharge pipe 9.5 to pass through is rotatably connected inside the movable hole 9.2.1. The sliding member 9.2 is provided with a threaded hole 9.2.3 that is threaded to the reciprocating screw 9.3.

[0012] Furthermore, a counterweight 12 is provided on the left side of the lower end of the material bucket 1, and through holes are provided on the hinge rod 2 and the counterweight 12, with an elastic element 13 connecting the two through holes.

Detailed Implementation

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] See Figures 1 to 10 This invention provides a column section adhesive coating device for mixed tower hoisting, comprising a material barrel 1. A friction damper is installed at the upper end of the material barrel to increase stability at high altitudes. This device is existing technology. A hinge rod 2 is elastically hinged to the left side of the outer wall of the material barrel 1. A rotating rod 3 is rotatably and vertically installed on the right side of the outer wall of the material barrel 1. Second hanging ears and stabilizing blocks 15 are respectively installed on the left and right sides of the lower end of the material barrel 1. The hinge rod 2 is hinged to the second hanging ears, and the rotating rod 3 rotates around the stabilizing blocks 15. Rubber wheels are installed at the lower ends of both the hinge rod 2 and the rotating rod 3. To drive the device to move along the cylinder section and to increase the friction between the cylinder sections to prevent the device from tipping over, the rubber wheel at the hinge rod is rotatably connected, while the rubber wheel at the rotating rod is fixedly connected. Rollers 4 are provided around the bottom of the material barrel 1. The rollers are universal wheels. A gear pump 5 and a servo motor 6 are provided at the lower end of the material barrel 1. The inlet of the gear pump 5 is connected to the outlet of the material barrel 1. The rotating rod 3 and the gear pump 5 are driven by a dual-drive assembly 7 connected to the servo motor 6. A roller brush 8 is twisted to the bottom of the material barrel 1 and located behind the two rear rollers 4. A dual-drive assembly driven by a servo motor drives the rotating rod and gear pump to operate simultaneously. The rubber wheel of the hinge rod presses against the outer wall of the cylinder section, causing the rubber wheel of the rotating rod to press against the inner wall of the cylinder section. The rubber wheel on the rotating rod makes the device move forward at a constant speed along the cylinder section, while the gear pump makes the glue in the material bucket fall at a constant speed. The speeds of the two are directly proportional. The subsequent roller brush passes over the glue falling on the cylinder section, thereby applying the glue to the cylinder section. After the device moves forward one circle along the cylinder section, it returns to its original position, thus automatically completing the glue application work on the upper surface of the cylinder section.

[0019] The dual-drive assembly 7 includes a first gear 7.1 keyed to the output shaft of the servo motor 6, a second gear 7.2 meshing at the front end of the first gear 7.1, a worm gear 7.3 keyed to the second gear 7.2 connected to the gear shaft of the gear pump 5, and a worm wheel 7.4 meshing with the worm gear 7.3 keyed to the upper end of the rotating rod 3. The servo motor drives the second gear to rotate via the first gear, and the second gear drives the worm wheel and gear shaft to rotate simultaneously via the worm. The gear shaft drives the gear pump to make the glue in the barrel fall at a uniform speed, and the worm wheel drives the rotating rod to rotate, causing the rubber wheel on the rotating rod to roll on the inner wall of the cylinder section, thereby moving the device along the cylinder section.

[0020] It also includes a spreading assembly 9 for spreading the glue from the gear pump 5. The spreading assembly 9 includes a slide rail 9.1 horizontally arranged in the middle below the material tank 1. Connecting strips are symmetrically connected to the left and right sides of the lower end of the material tank. The slide rail is horizontally fixed to the two connecting strips. A sliding member 9.2 located below the gear pump 5 is slidably mounted on the slide rail 9.1. The sliding member 9.2 moves left and right under the drive of the gear shaft of the gear pump 5. The outlet of the gear pump 5 is connected to a discharge pipe 9.5 passing through the sliding member 9.2. The discharge pipe has moderate hardness. A reciprocating screw 9.3 is rotatably arranged in front of the slide rail 9.1 and screwed to the sliding member 9.2. The reciprocating screw 9.3 is connected to the gear shaft of the gear pump 5 through a toothed belt 9.4. Toothed pulleys are keyed to both the reciprocating screw and the gear shaft. The rotating gear shaft drives the reciprocating screw to rotate, which in turn drives the sliding component to move back and forth. The sliding component causes the lower end of the discharge pipe to swing back and forth, and in conjunction with the forward-moving device, the glue coming out of the discharge pipe is spread out on the cylinder in an S-shape. The subsequent roller brush can then evenly spread the glue on the cylinder.

[0021] Before the adhesive falls onto the drum section, a brush that swings left and right can preemptively clean the dust and impurities on the drum section, thereby improving the adhesive's effectiveness. The system also includes a first lug fixed to the middle of the lower end of the material tank 1 and located in front of the gear pump 5. A hinge bar 10, driven by a sliding member 9.2, is hinged to the first lug. The end of the hinge bar 10 is equipped with a brush 11 for cleaning dust from the drum section. Driven by the sliding member, the hinge bar swings left and right, and the brush on the hinge bar automatically cleans the dust and impurities on the drum section before the adhesive.

[0022] The hinge 10 swings symmetrically left and right along the longitudinal section of the material barrel 1, with the swing angle of the hinge 10 being greater than or equal to 30 degrees and less than or equal to 45 degrees. Preferably, the swing angle of the hinge is 35 degrees, and the cleaning range of the brush on the hinge is greater than the range of the discharge pipe falling onto the barrel section.

[0023] See Figure 2 , Figure 10The upper end of the sliding member 9.2 has a movable hole 9.2.1. A sleeve 9.2.2, through which the discharge pipe 9.5 passes, is rotatably connected within the movable hole 9.2.1. The sleeve swings with the lower part of the discharge pipe, preventing the lower part of the discharge pipe from bending. When the sliding member moves to the left or right end, the lower part of the discharge pipe is in an inclined state, allowing the discharged glue to spread over a larger area and cover the upper surface of the cylinder section as much as possible. A transverse opening is provided at the sliding member 9.2... The reciprocating screw 9.3 is screwed into the screw hole 9.2.3. The middle of the front end of the sliding member 9.2 is longitudinally provided with a cylinder 9.2.4 for driving the hinge member 10 to swing. The sliding member moves back and forth, causing the cylinder to swing back and forth along the first lug. The brush on the hinge member will clean the upper end face of the cylinder section before the glue falls. The end of the cylinder 9.2.4 is provided with a limiting post 9.2.5 for limiting the hinge member 10.

[0024] A counterweight 12 is provided on the left side of the lower end of the material bucket 1. Through holes are provided on the hinge rod 2 and the counterweight 12, and an elastic element 13 is connected between the two through holes. The counterweight can keep the center of gravity of the device in the middle position, thereby stabilizing the device when working at height. The elastic element can press the rubber wheel on the hinge rod against the outer wall of the cylinder section, so that the rubber wheel of the rotating rod is also pressed against the inner wall of the cylinder section. The elastic element can be removed from the through hole of the counterweight before the device is placed on the cylinder section, and then hooked back onto the through hole of the counterweight after the device is placed on the cylinder section.

[0025] T-shaped connectors 14 are symmetrically installed on the front and rear sides of the middle of the material hopper 1. Rollers 4 are symmetrically arranged on the left and right sides of the connectors 14. The roller brush 8 is hung on the rear connector 14, and a torsion spring connects the roller brush 8 to the connector 14. From front to back, the components are a brush, a discharge pipe, and a roller brush. Under the action of the torsion spring, the roller brush is pressed against the cylinder section, so that the roller brush can evenly apply glue to the cylinder section.

[0026] The specific workflow of this invention is as follows: The device is placed on the cylindrical section and the elastic element is hooked in place. The rubber wheel on the hinge rod presses against the outer wall of the cylindrical section, and the rubber wheel on the rotating rod also presses against the inner wall of the cylindrical section. Figure 6 , Figure 9 As shown, the servo motor drives the second gear through the first gear, which in turn drives the worm wheel and gear shaft through the worm gear. The worm wheel drives the rotating rod, causing the rubber wheel on the rotating rod to roll against the inner wall of the cylinder section, thus propelling the device forward along the cylinder section. The gear shaft drives the gear pump to make the glue in the barrel fall at a uniform speed. The rotating gear shaft drives the reciprocating screw, which in turn drives the sliding part to move back and forth. The sliding part causes the hinge to swing left and right. The brush on the hinge automatically cleans the dust and impurities on the cylinder section before the glue falls. At the same time, the sliding part causes the lower end of the discharge pipe to swing back and forth, which, in conjunction with the forward movement of the device, makes the glue coming out of the discharge pipe at a uniform speed spread out in an S-shape on the cylinder section. Figure 7 As shown, the roller brush that passes by will spread the glue evenly on the cylinder section. After the device moves around the cylinder section once, it returns to its original position, which can automatically complete the glue application work on the upper surface of the cylinder section. The staff can then remove the device from the cylinder section.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
