Building construction steel pipe outer wall punching device facilitating accurate positioning

Abstract

The invention discloses a building construction steel pipe outer wall punching device facilitating accurate positioning. The punching device comprises a base, wherein a first fixing rod is fixedly mounted on one side of the top end of the base, a first fixing plate is arranged right above the base, a first hinge block is fixedly mounted on one side of the bottom end of the first fixing plate, the top end of the first fixing rod extends into the first hinge block, and the first hinge block is internally hinged with a first hinge pin. Through the arrangement of a first steel wire rope and a second steel wire rope, the distance between adjacent holes can be guaranteed by loosening the first steel wire rope at the same distance every time, the second steel wire rope guarantees linear running of the device, and therefore the regularity of the holes is guaranteed, and when the punching angle needs to be adjusted, for example, when eight holes need to be punched in the same position, it is only needed to insert the same number of insertion blocks into multiple insertion grooves formed in a second mounting disc, and therefore punching work can be conducted on the multiple different holes at the same time without turning over the steel pipe, operation is easy and convenient, and time and labor are saved.

Description

Technical field [0001] The present invention relates to the field of steel pipe punching, and more particularly to a steel pipe outer wall punching device for facilitating precision positioning. Background technique [0002] When the existing steel pipe punching device needs to clamp the steel pipe to ensure that it does not loosen, then marks the punch position in advance to ensure that the punching work is carried out, but the existing device is mostly used. The hand-held punch is punched, and there are some shortcomings. First, the clamping removal of the steel pipe is too trouble, affecting the efficiency, and labeled a good position in advance, and a lot of operation time is carried out for a number of different angles on the inner wall of the steel pipe. When the punch is arranged, it is necessary to flip the steel pipe, and the process is more wasteful, resulting in a decrease in working efficiency. Inventive content [0003] In order to solve the above presence, the pres...

Problems solved by technology

[0002] When the existing steel pipe punching device is working, it is necessary to clamp the steel pipe to ensure that it will not loosen, and then mark the punching position in advance to ensure the normal progress of the punching work, but most of the existing devices use There are some deficiencies in punching holes with a hand-held punching machine. First, the clamping and dismounting of the steel pipe is too troublesome, which affects work efficiency, and it also wastes a lot of operating time to mark the position in advance. For the inner wall of the steel pipe, multiple different angles When arranging and punching, it is necessary to turn over the steel pipes, and the process is more time-consuming, resulting in a decrease in work efficiency
