Description

TECHNICAL FIELD

[0001] The utility model belongs to prestressed anchorage device clamping piece processing technical field, specifically related to a hinge drilling device for prestressed anchorage device clamping piece processing. BACKGROUND

[0002] It is suitable for the anchorage device used in the prestressed tension of concrete in the process of engineering construction. It is often used in bridge construction, and is pre-installed positioning, then pouring concrete, and is buried at both ends of the concrete, that is, the two end heads of the corrugated pipe, which is provided for the stable effect of the jack during tensioning.

[0003] Through the translation mechanism, the two support frames move towards each other to clamp the clamping piece. When the other side needs to be reamed, the lifting starts to drive the clamping part to lift, and at the same time of lifting, through the setting of the rotating mechanism, the clamping part can be turned over, so that the double sides of the clamping piece can be reamed, without frequent operation, effectively reducing the labor intensity of workers, and improving the efficiency of reaming.

[0004] However, during the reaming operation, the prestressed anchorage clamping piece is processed by the reaming machine, which produces metal chips. These chips will then fall on the two-way threaded rod. When the two-way threaded rod surface is attached with metal chips, the support frame will be hindered during movement, thereby causing unnecessary friction and wear between the two-way threaded rod and the support frame. Specifically, the metal chips, as hard particles, are clamped between the threads of the threaded rod and the contact surface of the support frame, which exacerbates the mutual wear of the two during movement, affecting the stability and service life of the entire structure.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application. Embodiment one

[0022] Please refer to Figures 1-4 ​The utility model provides the following technical scheme: A reaming device for prestressed anchor clamping piece processing, including reamer 1 and the workstation 2 of reamer 1 assembly on, the inside wall of the top end support frame of workstation 2 is connected with clamping block 3, and the outside wall of the top end support frame of workstation 2 is equipped with first motor 10 and is connected with clamping block 3, and the top end support frame of workstation 2 is connected with two -way threaded rod 8, and one end of two -way threaded rod 8 is equipped with second motor 9 and is connected with two -way threaded rod 8, and the top front end of workstation 2 is connected with fixed block 4, and the top end of fixed block 4 is connected with mounting plate 5, and the outside wall of mounting plate 5 is equipped with cooling fan 6, and the outside wall of fixed block 4 is equipped with electric rod 7, and the telescopic end of electric rod 7 is connected with cleaning brush 15.

[0023] In the preferred embodiment, the fixed block 4 is in the shape of a " " character, and the cleaning brush 15 is connected to the fixed block 4 through the electric rod 7.

[0024] In the preferred embodiment, the cleaning brush 15 is at the same height as the two-way threaded rod 8.

[0025] In the preferred embodiment, the cooling fan 6 is provided with three equally spaced cooling fans.

[0026] In the preferred embodiment, first, the second motor 9 drives the two-way threaded rod 8 to rotate, allowing the two clamping blocks 3 to move closer to or further away from each other. When the clamping blocks 3 move closer to each other, it is convenient to fix the prestressed anchor clamping piece, and then the prestressed anchor clamping piece is securely placed in the recess of the clamping block 3. Next, the reamer 1 is used to ream the prestressed anchor clamping piece. After that, the first motor 10 is started to drive the clamping block 3 to rotate, realizing the reverse reaming of the prestressed anchor clamping piece.

[0027] In addition, during the reaming process of the prestressed anchor clamping piece, metal debris generated will fall on the two-way threaded rod 8. At this time, the cooling fan 6 is manually started, and the power of the electric rod 7 is turned on at the same time. The telescopic end of the electric rod 7 is extended, pushing the cleaning brush 15 to approach and cover the surface of the two-way threaded rod 8. Then, the second motor 9 is started again to make the two-way threaded rod 8 rotate, and the metal debris on the surface of the two-way threaded rod 8 is removed by the cooperation of the rotating two-way threaded rod 8 and the cleaning brush 15. After the processing of the prestressed anchor clamping piece is completed, the rotating two-way threaded rod 8 moves away from each other, and the prestressed anchor clamping piece is removed.

[0028] It is worth noting that the cleaning brush 15 is made of nylon brush or steel wire brush.

[0029] Steel wire brush: suitable for hard metal debris, the hardness of the brush should be moderate to avoid damaging the threads. Nylon brush: suitable for soft debris or high surface requirements. The specific situation can be selected according to the actual situation.

[0030] Further, the cleaning brush 15 can be extended or retracted by the electric rod 7 without affecting the normal movement of the clamping block 3 or the movement of the support frame, which facilitates the use of the clamping block 3. Then, the cooling fan 6 and the cleaning brush 15 can be used when the reaming device is started. Embodiment two

[0031] Please refer to Figures 1-4 The top end of the clamping block 3 is connected with a support block 11 in the shape of "L", and the top end of the support block 11 is connected with a threaded rod 12 through a threaded hole.

[0032] In the preferred embodiment, the end of the threaded rod 12 is connected with a limiting block 13, and the top end of the clamping block 3 is provided with a groove 14.

[0033] In the preferred embodiment, the size of the groove 14 is larger than that of the limiting block 13, and the limiting block 13 is connected with the support block 11 through the threaded rod 12.

[0034] In the embodiment, after the prestressed anchor clamping piece is fixed by the clamping block 3, the threaded rod 12 is manually rotated to be lowered, which drives the limiting block 13 to pass through the groove 14 and enter the recess of the clamping block 3, and at the same time, the prestressed anchor clamping piece is pressed to ensure its stability. During this process, even if the clamping block 3 is driven to rotate by the first motor 10, the prestressed anchor clamping piece can remain in a stationary state, which significantly improves the stability and safety of the operation.

[0035] Finally, it should be pointed out that the above description is only the preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
