Description

Technical Field

[0001] The utility model belongs to the technical field of angle steel towers, and particularly relates to a modular steel pipe rod used for angle steel towers. Background Art

[0002] Angle steel tower is a steel structure tower that uses angle steel as the main component and is connected by welding or bolts. It is mainly used for overhead line support and protection in the fields of electricity, communications, radio and television. In order to improve the stability of some old angle steel towers, workers are often required to install steel pipe rods on the tower body of the angle steel tower to reinforce the tower body.

[0003] At present, in the process of reinforcing the diagonal steel tower body by steel tube rods, since the lower end of the tower body is wider as a whole and the upper end of the tower body is narrower, a large number of measurements are required in the production of the steel tube rods, and then the corresponding steel tube rods are produced and installed on the tower body for fixation, which is very inconvenient. Moreover, although the length of the steel tube rod is certain, there will always be a certain gap difference after the tower body is fixed, and these gap differences will also affect the tensile fixation effect of the steel tube rod. Utility Model Content

[0004] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a modular steel pipe rod for an angle steel tower to solve the problems mentioned in the background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A modular steel pipe rod for an angle steel tower, comprising a main steel pipe rod, a first steel pipe rod and an angle steel fixing block, wherein the first steel pipe rod is symmetrically threadedly connected to the left and right sides of the main steel pipe rod, a first thread groove is provided on the outer side of one end of the first steel pipe rod of the left half of the main steel pipe rod, and a second thread groove is provided on the outer side of one end of the first steel pipe rod of the right half of the main steel pipe rod, a connecting mechanism is provided at one end of the first steel pipe rod away from the main steel pipe rod, a second steel pipe rod is fixedly installed at one end of the first steel pipe rod through the connecting mechanism, an end of the second steel pipe rod away from the first steel pipe rod is fixedly connected to an axle block, one side of the angle steel fixing block is fixedly connected to an axle seat, and an end of the axle block away from the second steel pipe rod is rotatably connected to the inner side of the axle seat;

[0007] The connecting mechanism includes a fixing bolt, a first mounting plate and a second mounting plate. The first mounting plate is fixedly connected to an end of the first steel pipe rod away from the main steel pipe rod, and the second mounting plate is fixedly connected to an end of the second steel pipe rod away from the shaft block. The first mounting plate and the second mounting plate are plug-in connections, and through holes are provided on the inner sides of the first mounting plate and the second mounting plate.

Through the connecting mechanism on the first steel pipe rod, the first connecting rod and the second connecting rod with the angle steel fixing block can be conveniently connected and installed.

[0008] As an optimal technical solution, the outer side of the shaft block is symmetrically fixed with a pin shaft, and the shaft block is rotatably connected to the inner side of the shaft seat through the pin shaft. The pin shaft installed on the outer side of the shaft block can facilitate the rotation of the shaft block inside the shaft seat.

[0009] As a preferred technical solution, positioning grooves are symmetrically provided on the outer side of the angle steel fixing block, and fixing holes are provided on the inner side of the angle steel fixing block. The fixing holes on the angle steel fixing block can facilitate the connection and installation of the angle steel fixing block and the angle steel of the angle steel tower. The positioning grooves on the angle steel fixing block can facilitate the angle steel fixing block to be abutted against the plate surface of the angle steel through the positioning grooves along the edge of the angle steel, thereby facilitating the connection and installation of the angle steel fixing block and the angle steel.

[0010] As a preferred technical solution, an operating head is fixedly connected to the outer side of the middle part of the main steel pipe rod, and rod grooves are opened at equal angles on the outer side of the operating head. Through the operating head on the main steel pipe rod, a rod-shaped tool can be easily inserted into the operating head to rotate the main steel pipe rod.

[0011] As a preferred technical solution, a positioning block is fixedly connected to the side of the first mounting disk facing the second mounting disk. The first mounting disk is plug-connected to the second mounting disk through the positioning block. The positioning block on the first mounting disk can facilitate the plug-in installation of the first mounting disk and the second mounting disk.

[0012] As an optimal technical solution, an end groove is opened at a through hole on one side of the first mounting plate close to the first steel pipe rod, and the end of the fixing bolt is inserted into the inner side of the end groove. Through the positioning groove on the first mounting plate, it can be conveniently inserted into the end of the fixing bolt, thereby facilitating the positioning of the fixing bolt.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] First, after the angle steel fixing blocks indirectly connected at both ends of the main steel pipe rod are fixed on the angle steel, the main steel pipe rod is rotated so that the two first steel pipe rods with opposite threads connected to the inner threads at both ends of the main steel pipe rod can approach each other, so that the two angle steel connection points on the angle steel tower can be tightened, thereby avoiding the gap difference during the installation process, which affects the stability of the angle steel tower reinforcement;

[0015] Second, when connecting the first steel tube rod and the second steel tube rod, the first mounting plate on the first steel tube rod is inserted into the second mounting plate, and then the threaded end of the fixing bolt is passed through the through holes on the first mounting plate and the second mounting plate, and then the threaded end of the fixing bolt is thread-locked by the locking nut, so that the first steel tube rod and the second steel tube rod can be conveniently installed and used in combination.
