Description

A chamfering tool for transmission line foundation construction

technical field

The utility model belongs to the field of electric power construction tools, in particular to a chamfering tool for power transmission line foundation construction.

Background technique

The main construction of the cast-in-place pile foundation for transmission lines is to fill the cylindrical outer sleeve formwork with materials. After the material is filled, the frustum-shaped line foundation needs to be chamfered according to the process requirements, and the chamfers are required to be uniform; After the line foundation is solidified, remove the standard outer edge formwork to complete the practical use of the line foundation. The current chamfering process is performed by manual hand-held chamfering tools. It is difficult to maintain a uniform standard for the chamfering size, and the quality of the chamfering is greatly affected by human factors.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a chamfering tool for foundation construction of transmission lines with simple structure, reasonable design, convenient use and reliable process.

The utility model solves its technical problem and realizes by taking the following technical solutions:

A chamfering tool for power transmission line foundation construction, comprising an outer circular chamfering device, a vertical rod, an extension rod, a horizontal rod and a positioning wheel. The outer circular arc chamfering of the upper edge of the line foundation is prepared, and a vertical rod is fixed vertically on the upper end of the outer circular chamfering device. , the lower end of the cantilever end of the cross bar is equipped with a positioning wheel.

Moreover, an auxiliary wheel is laterally installed in the middle part of the extension rod, and the auxiliary wheel is used for supporting on the inner wall of the outer cylindrical sleeve template.

Moreover, the connecting position of the vertical rod and the extension rod is coaxially engaged with an adjusting sleeve with an internal thread. The upper end of the vertical rod is formed with external threads, and the lower end of the extension rod is also formed with external threads. Distance between filleters.

Advantage and positive effect of the present utility model are:

The utility model has the advantages of simple structure, convenient installation, convenient use, good reliability, effectively guarantees the technical size of the chamfering, ensures the standard size of the chamfering of the foundation, makes the outline of the circuit foundation uniform and standard, and has good chamfering quality.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A chamfering tool for power transmission line foundation construction, comprising an outer circular chamfering device 8, a vertical rod 7, an extension rod 3, a cross bar 2 and a positioning wheel 1, the lower part of the outer circular chamfering device is formed with a concave arc surface 9, The arc surface is used to prepare the outer circular arc chamfering of the upper edge of the line foundation 11, and a vertical rod 7 is fixed vertically on the upper end of the outer circular chamfering device, and the vertical rod drives the outer circular chamfering device to perform rounding and chamfering along the edge of the circuit foundation Corner processing.

The innovation point of the present utility model is:

In order to limit the position, an extension rod is coaxially connected to the upper end of the vertical rod, and a cantilevered cross bar is formed on the upper end of the extension rod. A positioning wheel is installed at the lower end of the cantilever end of the cross rod. The upper edge of the circular sleeve template 10 moves, and the outer cylindrical sleeve template is a standard cylindrical structure, which effectively limits the processing position of the outer circular chamfering device, thereby ensuring the consistency of the chamfering.

In order to enhance the positioning accuracy, an auxiliary wheel 4 is horizontally installed in the middle of the extension rod, and the auxiliary wheel is used to support on the inner wall of the outer circular sleeve formwork, so that the distance between the outer circle chamfering device and the outer circular sleeve formwork is kept consistent.

In order to be suitable for the construction of line foundations with different heights, an adjusting sleeve 5 with internal threads is installed in the coaxial engagement between the vertical rod and the extension rod, the upper end of the vertical rod is made with external threads 6, and the lower end of the extension rod is also made with external threads , turning the adjusting sleeve can extend or shorten the length of the vertical rod and the extension rod, thereby adjusting the distance between the positioning wheel and the outer circle chamfering device.

Although the embodiments and accompanying drawings of the utility model are disclosed for the purpose of illustration, those skilled in the art can understand that various replacements, changes and modifications can be made without departing from the spirit and scope of the utility model and the appended claims. It is possible, therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
