Description

Technical Field

[0001] The invention belongs to the field of bridge construction, and particularly relates to an anchor rod sealant scraping device. Background Art

[0002] The main cable anchoring system of a bridge consists of a rear anchor beam and anchor rods. To avoid tensile cracking of the local concrete around the anchor rods due to the bonding between the anchor rods and the anchor concrete, it is necessary to wrap the outer periphery of the anchor rods with an ultra-low modulus and high-elongation polysulfide anti-corrosion sealant (hereinafter referred to as sealant) before pouring the anchor concrete.

[0003] The anchor rod where sealant is applied is I-shaped, meaning the main body of the anchor rod is made of I-steel. When applying sealant, the anchor rod is usually placed on the ground, the top side is coated, and then the rod is flipped so that all four sides face upward, and the coating is applied sequentially. This coating method is cumbersome and inefficient. Setting up a bracket to support the anchor rod to facilitate simultaneous coating of multiple surfaces also prevents direct coating of the area where the bracket and the anchor rod come into contact. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an anchor rod sealant scraping device to solve the problem that a bracket is set up to support the anchor rod so as to facilitate simultaneous coating of multiple surfaces of the anchor rod, and the contact part between the bracket and the anchor rod cannot be directly coated.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An anchor rod sealant scraping device includes a supporting assembly, a traveling assembly and a scraping assembly. The supporting assembly includes a support platform for supporting both ends of the anchor rod and a support member for supporting the middle part of the anchor rod. The supporting member includes a base and a support rod arranged on the base along a vertical sliding motion; the scraping assembly includes a scraping frame for being sleeved on the outside of the anchor rod, and the inner wall of the scraping frame is connected to a plurality of rollers along the circumferential rotation. The rollers are used to contact the outer wall of the anchor rod and move on the outer wall of the anchor rod. An inclined scraping plate is fixed to the end of the scraping frame. The free end of the scraping plate is facing away from the direction of the roller and inclined toward the inner wall of the scraping frame. The scraping plate is used to scrape the sealant on the outer wall of the anchor rod; the traveling assembly is used to drive the scraping assembly to move on the ground.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. Extrude the sealant onto the anchor rod surface and use a scraper to smooth the sealant evenly across the surface. A scraper frame is positioned directly over the outside of the anchor rod, and the scraper moves with it, allowing sealant to be applied simultaneously to multiple surfaces of the anchor rod. The roller facilitates the scraper frame's movement along the anchor rod.

[0009] 2. In the initial state, hoist the A end of the anchor rod onto one of the support platforms, then hoist the B end of the anchor rod, and place the support member below the middle of the anchor rod. Adjust the height of the support rod so that the support rod assists in supporting the anchor rod and prevents the B end of the anchor rod from touching the ground, so as to facilitate the sleeve of the scraping frame from the B end of the anchor rod to the anchor rod. After the scraping frame gradually moves away from the B end of the anchor rod, that is, after the B end of the anchor rod has been painted, support the B end of the anchor rod with another support platform and slide the support rod so that the support rod is away from the anchor rod. This facilitates the removal of the support member from under the anchor rod to prevent the support member from hindering the movement of the scraping frame. When the scraping frame continues to move near the A end of the anchor rod, remove the support platform at the A end of the anchor rod and re-place the support member under the anchor rod for auxiliary support. Then, continue to move the scraping frame to paint the A end of the anchor rod.

[0010] The arrangement of the walking assembly facilitates the movement of the scraper frame on the one hand, and also enables the scraper frame to contact the ground on the other hand, so as to play a role in supporting the anchor rod during the movement of the scraper frame.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings, and specific implementation methods will be given.

[0018] like Figure 2 、 Figure 3 As shown, the anchor rod sealant scraping device includes a support assembly, a walking assembly and a scraping assembly. The support assembly includes a support platform 11 for supporting both ends of the anchor rod 1 and a support member for supporting the middle part of the anchor rod 1. Specifically, the support member includes a base 9 and a support rod 10 vertically slidingly arranged on the base 9. The support rod 10 can be an electric telescopic rod with a telescopic function in the prior art, or a conventional cylinder or other structure in the prior art to drive the support rod 10 to slide. There are two support platforms 11, and a plurality of support legs 12 are circumferentially installed at the lower end of the support platform 11. Specifically, the support legs 12 are connected to the support platform 11 along a vertical sliding direction. The support platform 11 is provided with a slide groove for the support legs 12 to slide and embed. A micro cylinder for driving the support legs 12 to slide is fixed in the slide groove. A vertical through hole is provided in the middle of the support platform 11, and a slide rod 13 is slidably connected in the through hole. The upper end of the slide rod 13 extends out of the support platform 11 and is fixed with a support plate 14. The lower end of the slide rod 13 is rotatably connected to the second walking wheel 15. An embedding groove for the second walking wheel 15 to be embedded in the lower end of the support platform 11 is provided. When the second walking wheel 15 is embedded in the embedding groove, it cannot drive the support platform 11 to move.

[0019] Combine Figure 1 As shown, the scraping assembly includes a scraping frame 2 for being sleeved on the outside of the anchor rod 1. The inner wall of the scraping frame 2 is connected to a number of rollers 3 that rotate along the circumferential direction. The rollers 3 are used to contact the outer wall of the anchor rod 1 and move on the outer wall of the anchor rod 1. An inclined scraping plate 7 is fixed to the end of the scraping frame 2. The free end of the scraping plate 7 is facing away from the roller 3 and inclined toward the inner wall of the scraping frame 2. The scraping plate 7 is used to scrape the sealant on the outer wall of the anchor rod 1. The multiple scraping plates 7 around the scraping frame 2 are connected to form a shape consistent with the shape of the scraping frame 2, which is equivalent to a shrinkage setting of the end of the scraping frame 2 in the direction of the anchor rod 1.

[0020] The walking assembly is used to drive the scraping assembly to move on the ground. The walking assembly includes a first walking wheel 8 rotatably connected to the lower end of the scraping frame 2 and a traction member for pulling the scraping frame 2. Specifically, the traction member includes a traction seat 4, a traction wheel 5 rotatably connected to the traction seat 4, and a traction rope 6 wound around the traction wheel 5. One end of the traction rope 6 is fixed to the traction wheel 5, and the other end of the traction rope 6 is detachably connected to the scraping frame 2. A connecting plate is fixed to this end of the traction rope 6, and the connecting plate is bolted to the scraping frame 2. The traction seat 4 is also equipped with a motor for driving the traction wheel 5 to rotate.

[0021] During specific use, in the initial state, the supporting foot 12 is stored in the slide groove at the bottom of the supporting platform 11, and the second walking wheel 15 is in contact with the ground, which is convenient for moving the supporting platform 11. After the supporting platform 11 is moved to the desired position, the supporting foot 12 slides out of the slide groove and contacts the ground, and the supporting platform 11 is supported by the supporting foot 12. Then, the sliding rod 13 is slid to make the support plate 14 slide upward, and the second walking wheel 15 is embedded in the embedding groove.

[0022] Lift the A end of the anchor rod 1 onto one of the support platforms 11, then lift the B end of the anchor rod 1, and place the support member below the middle of the anchor rod 1, adjust the height of the support rod 10 so that the support rod 10 assists in supporting the anchor rod 1 and prevents the B end of the anchor rod 1 from touching the ground.

[0023] Then, sealant is placed on the surface of the anchor rod 1 starting from the end of the anchor rod 1B, so that the sealant covers the entire surface of the anchor rod 1. The scraping frame 2 is placed on the anchor rod 1 from the end of the anchor rod 1B, and the scraping frame 2 is moved. Specifically, the traction wheel 5 is rotated so that the traction rope 6 is gradually wound around the traction wheel 5, and the scraping frame 2 is then pulled by the traction rope 6. The scraping plate 7 moves with the scraping frame 2, and the sealant on the surface of the anchor rod 1 is evenly scraped and spread by the scraping plate 7.

[0024] After the scraping frame 2 gradually moves away from the end of the anchor rod 1B, that is, after the end of the anchor rod 1B has been painted, another support platform 11 is supported to the end of the anchor rod 1B, and the support rod 10 is slid so that the support rod 10 is away from the anchor rod 1, which makes it easy to remove the support member from under the anchor rod 1 to avoid the support member hindering the movement of the scraping frame 2.

[0025] When the painting frame 2 continues to move to the vicinity of the anchor rod 1A end, remove the support platform 11 at the anchor rod 1A end. When removing the support platform 11, first slide the slide bar 13 so that the second running wheel 15 contacts the ground. At the same time, the support plate 14 no longer contacts the surface of the anchor rod 1, making it easier to move the support platform 11. Then retract the support foot 12 into the slide slot to move the support platform 11. The support member is replaced under the anchor rod 1 for auxiliary support, and then the painting frame 2 continues to move to paint the anchor rod 1A end.

[0026] In another embodiment of the present invention, Figure 4 、 Figure 5 As shown, the scraping assembly also includes a glue barrel 16 for storing sealant and a bracket for securing the glue barrel 16. A glue dispensing block 21 is fixed to the scraping frame 2 between the scraping plate 7 and the roller 3. A glue cavity is defined within the glue dispensing block 21, and a glue hose 20 connects the glue cavity to the glue barrel 16. Specifically, the glue dispensing block 21 and the glue hose 20 are detachably connected. A connecting plate is secured to the end of the glue hose 20, which is bolted to the glue dispensing block 21. A glue outlet is defined at the free end of the glue dispensing block 21, communicating with the glue cavity.

[0027] The axis of the rubber barrel 16 is parallel to the axis of the traction wheel 5. A slide 24 is slidably connected to the rubber barrel 16 along its axis. A rubber inlet 22 and a rubber outlet 23 for communication with the rubber hose 20 are defined at one end of the rubber barrel 16. A circular ring 17 is fixed to the other end of the rubber barrel 16. A screw 19 is rotatably connected to the rubber barrel 16 and is threadedly connected to the circular ring 17. Screw 19 comprises a first section and a second section. The first section defines a spline groove, while the second section is fixed to a spline section 25 that mates with and slides in the spline groove. The second section of screw 19 is rotatably connected to the bracket. One end of screw 19 abuts or is fixed to slide 24, specifically the first section. A one-way bearing 18 is mounted on the other end of screw 19, specifically the second section. The one-way bearing 18 is connected to the traction wheel 5 via a gear drive or belt drive. Due to the structural arrangement of the screw 19 , the screw 19 does not need to extend into the sealant in the glue barrel 16 , thereby avoiding the problem that the screw 19 is difficult to clean.

[0028] During specific use, when the traction wheel 5 rotates forward to wind the traction rope 6, the traction wheel 5 drives the screw 19 to rotate forward, and the second section of the screw 19 rotates without making axial movement. While rotating, the first section of the screw 19 is acted upon by the ring 17 and moves along its axial direction, thereby pushing the slide 24 to move, pushing the sealant in the glue barrel 16 into the glue hose 20, and then discharged to the surface of the anchor rod 1 through the glue discharging block 21. During the above process, while the traction wheel 5 rotates and pulls the scraping frame 2 to move, the sealant is extruded onto the anchor rod 1, so that the sealant extrusion amount is adapted to the movement speed of the scraping frame 2, better controlling the sealant extruded onto the anchor rod 1, reducing waste, and also avoiding uneven scraping to a certain extent.

[0029] After the coating is completed, the rubber hose 20 and the traction rope 6 are removed and can be stored separately. When the glue is added to the glue barrel 16 through the glue inlet hole 22, the sealant pushes the slide plate 24 to slide back to its original position, and the first movement of the screw 19 is restored. During this process, when the screw 19 rotates, it is restricted by the one-way bearing 18 and will not drive the traction wheel 5 to rotate together.

[0030] In another embodiment of the present invention, Figure 4 As shown, a collection box 27 is fixed to the lower end of the scraping frame 2. The collection box 27 is located below the scraping plate 7 and has an open top. The collection box 27 is also located below the glue discharging block 21. A plurality of glue leakage holes 26 are provided at the lower end of the scraping frame 2. The collection box 27 can receive some of the fallen sealant to prevent it from falling onto the ground and being difficult to clean up. The glue leakage holes 26 can also allow the sealant that falls into the scraping frame to be discharged into the collection box 27 for disposal.
