Description

Technical Field

[0001] The utility model relates to the technical field of rust removal equipment, in particular to a surface rust removal equipment for prestressed anchor fittings. Background Technique

[0002] The anchor fitting can play an anchoring role and is a permanent anchoring device. In a concrete structure, it can transfer the tensile force to the inside and is also called a prestressed anchor fitting. It has many classifications. For example, there is a fixed-end anchor fitting, which is mainly installed at the end of the prestressed steel bar and generally needs to be buried in the concrete, so it is also called an extrusion anchor. There is also a zala anchoring, which can be used for the device of tensioning high-strength steel wires. In order to extend the service life of the anchor fitting, when the anchor fitting is eroded externally, it is necessary to carry out rust removal treatment on the anchor fitting.

[0003] In the prior art, the publicly disclosed CN219853841U discloses a rust removal and maintenance device with an anti-offset function, which relates to the technical field of rust removal devices. In this solution, the inner hole and the annular outer wall of the anchor fitting are polished by a polishing roller and a first polishing disc respectively. The extrusion and fixation by the extrusion rod and the support block can ensure the accuracy of the device when polishing the inner hole and the annular outer wall of the anchor fitting, so as to prevent problems with the polishing accuracy of the hole due to the offset of the anchor fitting.

[0004] However, the above solution uses a one-time polishing and rust removal method for the rust removal of the anchor fitting. Since the rust removal operation of the anchor fitting is mainly carried out by the polishing disc, affected by the limited contact surface between the polishing disc and the anchor fitting, there is extremely likely a phenomenon that the surface rust removal of the anchor fitting is not thorough, making it difficult to guarantee the sufficiency of rust removal.

[0005] Therefore, we propose a surface rust removal equipment for prestressed anchor fittings to solve the above drawbacks. Content of the Utility Model

[0024] Please refer to Figures 1-3 , a surface rust removal device for a prestressed anchor, comprising a rust removal box 1. On the left side inside the rust removal box 1, a rust remover accommodating cavity 2 is provided. Inside the top opening of the rust remover accommodating cavity 2, two positioning columns 7 are welded. At one end of each of the two positioning columns 7 away from the inner wall of the rust remover accommodating cavity 2, a through hole 16 is provided. At the bottom of the rust removal box 1, a first motor 4 is fixedly installed. The output end of the first motor 4 extends into the rust remover accommodating cavity 2 and is fixedly connected to a transmission disk 5. On the top surface of the transmission disk 5, two wire brush strips 6 are symmetrically installed. Between the two wire brush strips 6, a U-shaped clamp 8 is provided. On the opposite surfaces of the two wire brush strips 6, several clusters of grinding wires are arranged. The lower part of the U-shaped clamp 8 is sleeved with an anchor ring 9. On both sides of the upper end of the U-shaped clamp 8, convex columns 10 are welded. The convex columns 10 are connected to the through holes 16 on the positioning columns 7. On the right side of the rust removal box 1, an installation cavity 11 is provided. Inside the installation cavity 11, a second motor 12 is installed. The output end of the second motor 12 penetrates through the installation cavity 11 and is fixedly installed with a turntable 13. At the center of the top surface of the turntable 13, a hole wall grinding column 15 is detachably installed. On the top surface of the turntable 13, a grinding ring 14 is fixedly connected, and the grinding ring 14 is located outside the wall grinding column.

[0025] In this embodiment: By squeezing the upper end of the U-shaped clamp 8 towards each other, while causing the upper end of the U-shaped clamp 8 to deform and move towards each other, so as to facilitate the connection between the U-shaped clamp 8 and the two positioning columns 7. In this patent, we only use the first motor 4 and the second motor 12, and do not improve their structures and functions. Their setting methods, installation methods, and electrical connection methods, for those skilled in the art, as long as they are debugged and operated according to the requirements of their user manuals, will not be elaborated here. Moreover, both the first motor 4 and the second motor 12 are provided with their respective matching control switches, and the installation positions of the control switches are selected according to actual usage requirements, as long as it is convenient for the operator to operate and control.

[0026] Specifically, the U-shaped clamp 8 is composed of two steel bars and a limiting block 18 welded therebetween. The convex columns 10 are welded to the sides of the two steel bars of the U-shaped clamp 8.

[0027] In this embodiment: The setting of the limiting block 18 is adopted to provide support for the anchor ring 9, and the two steel bars facilitate the support of the anchor ring 9.

[0028] Specifically, several clusters of abrasive wires are provided on the surfaces of the wire brush strip 6 and the hole wall grinding column 15.

[0029] In this implementation: both the wire brush strip 6 and the hole wall grinding column 15 use abrasive wires to grind and remove rust from the anchor ring 9.

[0030] Specifically, two steel bars of the U-shaped fixture 8 are inserted into two of the inner holes of the anchor ring 9.

[0031] In this implementation: the two steel bars of the U-shaped fixture 8 are smaller in size than the inner hole diameter of the anchor ring 9, so as to fix the anchor ring 9 by the U-shaped fixture 8 and facilitate the grinding and rust removal of the side surface of the anchor ring 9.

[0032] Specifically, a rust remover solution is poured into the rust remover accommodating cavity 2. A drain nozzle 3 is opened through the lower surface of the rust removal box 1 to penetrate the rust remover accommodating cavity 2, and a valve is installed on the surface of the drain nozzle 3.

[0033] In this implementation: through the setting of the rust remover solution, chemical rust removal of the anchor ring 9 is facilitated. Through the setting of the drain nozzle 3, the rust remover solution can be discharged or filtered.

[0034] Specifically, a grinding surface is provided on the top surface of the grinding ring 14.

[0035] In this implementation: through the grinding surface of the grinding ring 14, it is applicable to the grinding of the end face of the anchor ring 9.

[0036] Specifically, a circular base 17 is welded to the bottom of the hole wall grinding column 15, and the surface of the circular base 17 is fixedly connected to the turntable 13 by flat head screws.

[0037] In this implementation: through the setting of the circular base 17, the hole wall grinding column 15 is detachable, so as to replace the hole wall grinding column 15 with a suitable size according to the actual inner hole size of the anchor ring 9.

[0038] Working principle: During operation, first pass the U-shaped fixture 8 through two of the inner holes of the anchor ring 9, and then place the U-shaped fixture 8 with the anchor ring 9 between the two positioning columns 7, so that the convex column 10 of the U-shaped fixture 8 is connected to the through holes 16 on the surfaces of the two positioning columns 7 until the side surface of the anchor ring 9 comes into contact with the polishing steel wires of the two wire brush strips 6 arranged facing each other. By starting the first motor 4 to drive the transmission disc 5 fixed to its output end to rotate, the two wire brush strips 6 fixed to the transmission disc 5 are prompted to rotate. As the two wire brush strips 6 rotate, the side surface of the anchor ring 9 can be polished and rust-removed specifically. During this process, the anchor ring 9 is immersed in the rust-removing agent solution configured in the rust-removing agent containing cavity 2 during the side surface polishing stage, and chemical rust-removing can be carried out comprehensively for the rust on the surface of the anchor ring 9. After the side surface polishing is completed, remove the anchor ring 9 from the U-shaped fixture 8, and then hold the anchor ring 9 close to the turntable 13. By starting the second motor 12 to drive the turntable 13 fixed to its output end to rotate, the hole wall polishing column 15 fixed at the center of the turntable 13 and the polishing ring 14 around it are prompted to rotate synchronously. The polishing ring 14 is suitable for polishing the end surface of the anchor ring 9, and the hole wall polishing column 15 with polishing steel wires is suitable for polishing the inner hole of the anchor ring 9, enabling the staff to polish the inner hole and the end surface of the anchor ring 9 specifically.
