Description

Technical Field

[0001] The utility model relates to an installation tool, and specifically to a device for batch installation of air duct bolts. Background Art

[0002] In the construction of public facilities, especially in the construction of rail transit and underground facilities, an air supply and exhaust system needs to be installed for ventilation. Among them, the installation of air ducts accounts for a large proportion. Especially in the installation process of air ducts, due to factors such as space design requirements and maintenance frequency, the designed positions of air ducts are usually relatively marginalized. This not only effectively protects the stability of the ventilation system but also reserves sufficient maintenance space for other pipelines such as water and electricity. When installing air ducts, because their locations are at the corners, the working space is severely insufficient. Ordinary installation tools install one bolt at a time, and it is very difficult to operate in the narrow gap between the air duct and the wall for the installation holes, causing great trouble to the construction and greatly reducing the construction efficiency. Summary of the Invention

[0003] In order to solve the technical problems of difficult installation operation and low construction efficiency, the utility model provides a device for batch installation of air duct bolts, which includes a drill gun, a transmission rod, a dust-proof cover, a pair of meshing gears and a nut row. It is characterized in that the drill gun provides power, the dust-proof cover is fixedly connected with the drill gun, the transmission rod is arranged inside the dust-proof cover and is adaptively connected to the drill bit hole of the drill gun at one end, one of the pair of meshing gears is fixedly installed on the transmission rod, and the other is rotatably installed at the bottom of the dust-proof cover. A through hole is provided on the dust-proof cover at its installation position, and a groove adapted to the bolt is provided at the bottom of the meshing gear installed here. The nut row is provided with an outer-large and inner-small groove adapted to the nut to prevent the nut from falling off. Through the structural setting of the utility model, it can adapt to installations in various spaces.

[0004] Further, in order to complete the installation of multiple bolts at one time, the number of the pair of meshing gears is more than two pairs.

[0005] Further, the pair of meshing gears are conical meshing gears, and the conical meshing gears are one of straight-tooth conical meshing gears, curved-tooth conical meshing gears, and helical-tooth conical meshing gears.

[0006] Further, in order to adapt to installations in different directions, one end of the dust-proof cover fixedly connected with the drill gun is provided with a through hole with internal threads, and is fixedly connected by screws through a mounting plate pre-set on the drill gun, and the dust-proof cover can be rotated in different directions by removing the screws.

[0007] Further, in order to ensure the stability of the operation, a rotatable bearing is installed at the rim of the through hole at the bottom of the dust cover for installing the meshing gear. An installation cylinder is fixedly installed on the inner ring of the bearing. The installation cylinder is fixedly connected to the meshing gear, and a groove adapted to the bolt cap is provided in the installation cylinder.

[0008] The beneficial effects of the present utility model are that it can adapt to the vast majority of installation working conditions, improve work efficiency, and save labor and working hours. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Note: The present drawings only schematically illustrate the structure, and do not limit the ratio, specific dimensions, and the number of meshing gears. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] In order to enable those skilled in the art to smoothly implement the present utility model, the structure and use of the present utility model will be described in detail below with reference to the drawings.

[0013] As Figure 1 shown, a device for batch installation of duct bolts includes a drill gun 1, a transmission rod 2, a dust cover 3, a pair of meshing gears 4 arranged in pairs, and a nut row 5. The drill gun 1 provides power. The dust cover 2 is fixedly connected to the drill gun 1. One end of the transmission rod 2 is arranged in the dust cover 3 and is adaptively connected to the drill bit hole of the drill gun 1. One of the pair of meshing gears 4 arranged in pairs is fixedly installed on the transmission rod 2, and the other is rotatably installed at the bottom of the dust cover 3. A through hole is provided on the dust cover 3 at the installation location. A groove adapted to the bolt is provided at the bottom of the meshing gear installed here. The nut row 5 is provided with an outer-large and inner-small groove adapted to the nut to prevent the nut from falling off.

[0014] In order to operate on multiple installation points at one time, the pair of meshing gears 4 arranged in pairs is more than two pairs. The pair of meshing gears arranged in pairs is a conical meshing gear, and the conical meshing gear is one of a straight-tooth conical meshing gear, a spiral-tooth conical meshing gear, and a skew-tooth conical meshing gear.

[0015] One end of the dust cover 3 fixedly connected to the drill gun 1 is provided with a through hole with internal threads, and is fixedly connected by screws through a mounting plate pre-set on the drill gun, and the dust cover 3 can be rotated in different directions by removing the screws to cope with bolts in different installation directions.

[0016] As Figure 2As shown, a rotatable bearing 7 is installed at the rim of the through hole 6 at the bottom of the dust cover 3 for installing the meshing gear. An installation cylinder 8 is fixedly installed on the inner ring of the bearing 7. The installation cylinder is fixedly connected to the meshing gear. A groove adapted to the bolt cap is provided in the installation cylinder.

[0017] During actual construction, first observe the direction of the duct bolt to be installed, adjust the screws of the dust cover and the mounting plate provided on the drill gun 1 to change the direction of the dust cover, and then tighten the screws for fixation; place the mounting nuts in the grooves on the nut row respectively, align them with the mounting holes, place the bolts, make good position correspondence with the meshing gear installed on the dust cover, start the drill gun to firmly install the bolts and nuts, and then withdraw the installation tools respectively to complete the construction process.

[0018] If there is a situation where the drill gun needs to be perpendicular to the arrangement direction of the mounting holes, the present utility model can be modified, for example: opening a hole in the middle of the dust cover, connecting it to the drill gun, making a split design of the transmission rod, and performing power conversion by adding a meshing gear so that installation operations can be carried out on both sides of the drill gun. Such simple modifications utilize the basic principle of the present utility model and are also within the protection scope of the present utility model.

[0019] The present utility model has a simple structure, is convenient to operate, has strong adaptability, high construction efficiency, and greatly saves working hours and labor.
