Description

TECHNICAL FIELD

[0001] The application relates to the wind power tower cylinder building technology field, in particular to a wind power tower cylinder joint mortar device. BACKGROUND

[0002] When the split type wind power tower cylinder is built and assembled, corresponding tower cylinder pieces of the same layer are spliced first, and then the spliced tower cylinder is gradually built upward by the tower crane device until the building is completed. When the tower cylinder pieces are spliced, different types of glue are first proportioned and stirred, then the glue is applied to the side surface of the tower cylinder through a scraper, and then irregular patterns are scraped on the surface of the glue. By increasing the bonding contact area between the two tower cylinder pieces, the mechanical interlocking force between the two tower cylinder pieces is improved. At the same time, the glue layer is extruded when the tower cylinder pieces are spliced, and the bubbles remaining in the glue can be discharged through the patterns to prevent local rainwater leakage caused by the remaining bubbles.

[0003] When the worker scrapes multiple patterns at the same time through the scraping teeth on the scraper, since most of the wind power tower cylinders are tapered cylinders that are narrow at the top and wide at the bottom, the vertical section widths of the tower cylinder pieces of different layers are different. When the patterns are scraped through the scraper, the distance between the adjacent two patterns also needs to be adjusted. If the distance between the scraping teeth is fixed and unchanged, the distance between the two patterns may be too small or too large for the tower cylinder pieces, which causes bubbles to gather and the glue to easily retain bubbles, increases the probability of rainwater penetration, and affects the mechanical interlocking force between the adjacent two tower cylinder pieces.

[0022] With reference to Figure 5 The outer sides of the two ends of the scraper 1 are symmetrically provided with the connecting rods 17, the bottom ends of the connecting rods 17 are rotatably installed with the rollers 18, the outer sides of the two sides of the scraper 1 are symmetrically fixedly installed with a pair of telescopic rods 19, the telescopic ends of the telescopic rods 19 are fixedly installed with the fixing rings 20, the fixing rings 20 are fixedly sleeved on the outer sides of the connecting rods 17, when the worker holds the handle 2 to slide the scraper 1 along the surface of the tower piece, the tower piece is in an arc shape, the two rollers 18 slide on the inner side wall and the outer side wall of the tower piece respectively, and then the scraper 1 is supported and limited when the worker holds the handle 2 to slide the scraper 1.

[0023] With reference to Figure 2 and Figure 5The interior of the scraper 1 is provided with a traction sliding groove 22, and the traction sliding groove 22 is arranged above the scraper rod 3. The interior of the traction sliding groove 22 is provided with a traction plate 21 which is limitingly and slidably arranged. The top end of the connecting rod 17 is fixedly provided with a traction rope 23. The end of the traction rope 23 which is away from the connecting rod 17 is movably penetrated through the top wall of the scraper 1 and is fixedly connected with the traction plate 21. The top of the traction plate 21 is symmetrically fixedly provided with two traction springs 24 which are sleeved outside the traction rope 23. The bottom end and the top end of the traction spring 24 are fixedly connected with the bottom of the traction plate 21 and the inner top wall of the traction sliding groove 22 respectively. When the thickness of the tower piece changes, the two rollers 18 and the connecting rod 17 slide to two sides, and then drive the traction plate 21 to slide upward through the traction rope 23. The traction spring 24 is compressed. The bottom of the traction plate 21 is limitingly and slidably connected with a plurality of connecting rotating rods 26. The bottom of the connecting rotating rod 26 is fixedly provided with an adjusting block 25. In the front view direction, the adjusting block 25 is triangularly arranged. The two sides of the adjusting block 25 are respectively matched with the adjacent scraper teeth 4. Therefore, when the thickness of the tower piece increases and the traction plate 21 slides upward, the traction plate 21 drives the adjusting block 25 to slide upward through the connecting rotating rod 26. The adjusting block 25 extrudes the scraper teeth 4, so that the distance between the adjacent two scraper teeth 4 increases. At the same time, the compression spring 9 is also compressed. When the thickness of the tower piece decreases, under the action of the traction spring 24 and the compression spring 9, the traction plate 21 slides downward, and at the same time, the distance between the scraper teeth 4 is also reduced. The situation that the distance between the adjacent two scraper teeth 4 is too small or too large is prevented. The area of the pattern is ensured, and the pattern on the surface of the glue is more uniform, and the shrinkage stress distribution of the glue is more uniform.

[0024] Working principle: When the same layer tower pieces are spliced, the worker evenly and flatly applies the mixed glue on the surface of the tower piece. The two rollers 18 are clamped on the inner side wall and the outer side wall of the tower piece. The position of the scraper teeth 4 is adjusted, and the pattern depth is controlled. Then the scraper 1 and the scraper teeth 4 are driven to slide along the surface of the tower piece in the vertical direction by the hand-held handle 2. When sliding, the handle 15 is pulled by the other hand, so as to drive the fixed block 11 to slide toward the handle 2 through the adjusting rope 14. At this time, the tension spring 12 is stretched, and the limit spring 13 is compressed. With the sliding of the fixed block 11, the adjusting plate 5 is driven to slide, and the extrusion of the scraper rod 3 by the main limit sliding groove 6 drives the scraper rod 3 to slide transversely, so that the scraper teeth 4 move in an arc in the horizontal direction. When the handle 15 is pulled to the side away from the scraper 1 in the push-pull sliding groove 16, the pulling force on the handle 15 is slowly reduced. Under the action of the tension spring 12 and the limit spring 13, the fixed block 11 gradually drives the adjusting plate 5 to slide reversely and reset. Then the reciprocating sliding of the handle 15 makes the scraper teeth 4 move and extrude the wave-shaped pattern on the surface of the glue, so as to prevent the simple linear motion of the scraper teeth 4 from causing the pattern area to be too small, affecting the bubble discharge, and avoiding the situation that the pattern area is reduced to affect the bubble discharge and reduce the bonding strength. When the different thickness of tower drum piece is glued and spliced, the two rollers 18 and the connecting rod 17 slide to both sides, and then the traction rope 23 drives the traction plate 21 to slide upward, the traction spring 24 is compressed, the traction plate 21 drives the adjusting block 25 to slide upward through the connecting rotating rod 26, the adjusting block 25 extrudes the scraping tooth 4, so that the distance between the two adjacent scraping teeth 4 is increased, and the pattern distance scraped by the scraping tooth 4 is also increased, and the extrusion spring 9 is also compressed. When the thickness of the tower drum piece is reduced, under the action of the traction spring 24 and the extrusion spring 9, the traction plate 21 slides downward, and at the same time, the distance between the scraping teeth 4 is also reduced. The pattern distance is changed by adjusting the distance between the scraping teeth 4, and when the two tower drum pieces are spliced, the pattern distance scraped is prevented from being too small or too large, the pattern area is ensured, the pattern on the surface of the glue is more uniform, the shrinkage stress distribution of the glue is more uniform, the deformation or crack caused by stress concentration is reduced, the rainwater penetration probability is reduced, and the overall stability and service life of the tower drum are improved.
