Description

A portable cutting tool holder

1. Fields:

The invention relates to the technical field of tool brackets for substation structures in the power industry, in particular to a portable cutting tool that can level concrete pole sections and pipe busbars at various work sites in the power industry and cooperate with a cutting machine to quickly complete cutting and welding work. Tool holder. the

2. Background technology:

At present, in the construction, acceptance and quality inspection and evaluation standards of the electric power industry, the cutting quality of concrete poles is often encountered. According to the requirements of the power substation structure quality specification, the substation equipment concrete structure support rod section, pipe busbar assembly and welding construction must meet the requirements of length deviation, horizontal error and verticality. Due to the unevenness of the site, the construction method, and the technical level of the personnel, the leveling and correction of the concrete pole section and the pipe busbar need to be adjusted with the sleepers and wood filling wedges. The leveling workload is heavy and imprecise, and the work is very difficult. These are limited by factors such as uneven construction site, cutting tools, and technical level of personnel, so it is difficult to guarantee the cutting quality of concrete pole sections. Therefore, overcoming various unfavorable factors in the actual cutting of concrete pole sections, assembly of pipe busbars, and welding construction on site, reducing the labor intensity of the staff, improving economic benefits, and ensuring cutting quality are urgent problems to be solved at this stage. the

3. Contents of the invention:

The purpose of the present invention is: in view of the existing technical situation, the design and development fundamentally solve the problem of leveling cushion sleepers and wooden wedge adjustments in the actual cutting of concrete pole sections and pipe busbar assembly work on site. The leveling workload is large and imprecise, and the labor intensity is high. Provide a portable cutting tool bracket with simple structure, small size, light weight, flexible and convenient use, adjustable leveling work, saving time and effort, adapting to any work site, convenient construction, and high construction accuracy. the

The technical solution adopted by the present invention to solve its technical problems is: a portable cutting tool bracket, characterized in that: it is composed of a base part and a bracket part, the base part is designed as a base 5 with a middle cavity, and the base 5 is a bracket Part, the base 5 in this technology can be designed to be rectangular, or it can be other various geometric shapes such as a circle and a square base 5. In order to reduce weight, carry and use conveniently, the middle of the base 5 of this technology is designed as a cavity. As shown in Figure 1. the

Said bracket part is composed of bracket 4, horizontal platform 3 provided on the top of bracket 4, bearing bracket 2 and its rolling bearing 1, wherein, bracket 4 is designed to adopt two brackets 4 of two-way screw-shaped screw bars that are identical and adjustable in height up and down. , the bearing bracket 2 and its rolling bearing 1 are set on the horizontal platform 3 at the top of the bracket 4, the design of the bearing bracket 2 and its rolling bearing 1 adopts two identical bearing brackets 2 and its rolling bearing 1, as shown in Figure 1, two of the present technology The distance between each bearing bracket 2 and its rolling bearing 1 is designed to just place the diameter of the concrete bar section that needs to be cut. the

The working principle and working process of this technology: First, select 5 or 6 portable cutting tool supports (as shown in Figure 1) of this technology and place them separately on a site suitable for actual cutting. Between the rolling bearings 1 on the bearing bracket 2 of the bracket (the distance between the bearings is adjustable depending on the rod section and the diameter of the pipe bus bar), after initially leveling the bracket by padding sleepers at the bottom corner of the bracket, use the two identical brackets of the bracket itself And the support 4 of the two-way screw bar with adjustable height up and down adjusts the placement height of the bar section and the busbar, and the adjustment range is designed to be ±15 cm to ensure that the bar section and the busbar are placed horizontally; The cutting machine is fixed at the cutting position of the concrete pole section. After the cutting position is determined, the designed two bearing brackets 1 and their rolling bearings 1 can make the concrete pole rotate on it. Therefore, using the concrete pole section on the support The cutting work can be carried out in a rotatable form to ensure the cutting accuracy requirements; thirdly, the rotatable form of the concrete pole section and the pipe busbar on the support can also be used to weld the pole section and the pipe busbar interface to ensure the quality requirements of the welding process. the

Compared with the existing technology, this technology has the characteristics of simple structure, small size, light weight, easy to use, easy to carry, time-saving and labor-saving, accurate cutting and welding dimensions, etc. It fundamentally solves the problem of leveling cushions in the actual work of cutting concrete pole sections on site. The adjustment of sleepers and wooden wedges, the leveling workload is heavy and imprecise, and the labor intensity is high. the
