The utility model has the advantages of convenient installation, labor saving and safety for installing the outer frame steel pipe, reusability and extremely low cost.
Description
Technical Field
The utility model belongs to the technical field of building construction, in particular to a scaffold and steel pipe construction technology in construction, and more particularly relates to an auxiliary device for installing an outer frame steel pipe.
Background
Along with the increasing height of new construction, the height of outer scaffold also increases thereupon, in order to prevent that debris that the top dropped from pounding personnel, the vehicle that the below passed by, also provide certain buffering guard action for the personnel eminence of top work when falling simultaneously, can install a round of safety net of hanging on the outer scaffold every a section distance. The safety net needs to be used with a horizontal or basically horizontal outward extending steel pipe, the outward extending outer frame steel pipe is fixed with a vertical steel pipe on the built scaffold at one to two points at the middle or the rear part, and the front end part of the outward extending steel pipe is extended outside without any supporting stress point. In addition to installing safety nets, there may be other situations where such outer frame steel pipes are required.
In the prior art, the outer frame steel pipe of the installation device is completely manually operated, an operator needs to grasp the balance steel pipe with force to install in the installation process, and the more the steel pipe extends out, the larger the downward gravity moment is, so that the installation operation has extremely high physical requirements on the operator. Once the steel pipe is not tightly gripped in the construction process, the steel pipe is easy to drop, and a high falling accident can be caused, so that serious consequences can be caused.
Disclosure of Invention
The utility model aims to provide an auxiliary device for installing an outer frame steel pipe.
For this purpose, the utility model adopts the following technical scheme: an auxiliary device for installing an outer frame steel pipe is characterized in that: the pulley comprises a pulley part and a clamp part, wherein the circumferential surface of the pulley is a concave surface, and the radial view of the pulley is an inward concave arc surface; the clamping part comprises two movably connected clamping rings, and the two clamping rings are connected and fixed to form a complete ring shape; the shaft of the pulley part is fixedly connected with one clamping ring of the clamp part, and the axial direction of the pulley part and the radial direction of the clamp part are on the same plane.
Further, one end of each clamping ring of the clamping hoop part is connected with the other end of each clamping ring in a pin rotating mode, and the other ends of the clamping rings are movably connected with the other ends of the clamping rings through screw nuts.
The fixed point of the clamp part and the pulley part is 90 degrees between the screw nut connecting end of the clamp part and the screw nut connecting end 0 Is not shown).
The diameter of the radial arc surface of the pulley part is larger than that of the outer frame steel pipe; the clamp parts are connected and fixed to form a ring, and are in interference fit with the vertical steel pipes.
The auxiliary devices are arranged in a group of two.
When the steel pipe lifting device is used, the clamp part is fixedly arranged at a proper position of the vertical steel pipe, the pulley part is horizontally arranged at the moment, the outer frame steel pipe to be constructed is placed on the circumference concave surface of the pulley part, the steel pipe can be easily pushed outwards, the pulley part provides support for the steel pipe, falling does not need to be worried about, and the labor intensity is greatly reduced. When the clamp is fixed, the bolt and the nut are faced to the operator, which is the most labor-saving positionDue to the pulley portion having 90 degrees 0 The pulley axis is thus parallel to the operating surface, i.e. the radial direction of the pulley is perpendicular to the operating surface, so that the most reasonable mounting angle is obtained. The two pulleys can form a circular cavity by combining the two pulleys and arranging the two pulleys one by one, and the outer frame steel pipe can pass through the circular cavity, so that the construction safety is further improved. If the field conditions permit, two or two pairs of the utility model can be arranged back and forth and horizontally or basically horizontally fixed on the front and back two vertical steel pipes, so that the two support points are provided in the outward pushing process of the outer frame steel pipes, and the operator saves more labor. When the outer frame steel pipe extends out to the right position, the utility model can be disassembled to the next construction point for repeated use after the fixing is completed.
The utility model has the advantages of convenient installation, labor saving and safety for installing the outer frame steel pipe, reusability and extremely low cost.

Detailed Description
See fig. 1 and 2. The embodiment consists of a pulley part 1 and a clamp part 2, which are welded and fixed at the joint. The pulley part is provided with a pulley shaft 11 and a circumferential surface 12, wherein the circumferential surface 12 is concave and is in a concave semicircular shape when seen from the radial direction; the clamp part 2 comprises two movably connected semicircular clamping rings, a pin 21 rotatably connects the two semicircular clamping rings at one end, and a screw 22 and a nut 23 are connected at the other end through the other pin 21. In the state of fig. 2, the screw 22 and the nut 23 are mounted on one of the semicircular clasps separately from the other semicircular clasp; in the state of fig. 1, the two semicircular snap rings are fixedly connected by a screw nut, and the clip part 2 forms a complete annular shape.
See fig. 3 and 4. The vertical steel pipe 3 is an existing device. The two present embodiments are fixedly installed at a set height of the vertical steel pipe 3 one above the other, and the outer edges of the two pulley portions are connected, so that the two circumferential concave surfaces 12 form a cavity, and a complete round hole is formed when the pulley portions are viewed radially. The outer frame steel pipe 4 can pass through the round hole and is fixed with the vertical steel pipe 3 after extending out for a set length.
