[0035] Embodiment 1

[0036] At present, the installation and fixation of the expansion bolts at the bottom of the roof is generally carried out by setting up scaffolding or placing a lift under the roof. The staff stands at a high altitude through the lift or scaffolding and uses a wrench to install the expansion bolts in the expansion bolt holes. This requires a large amount of turnover materials or machinery rental fees, and the movement and use of the construction process requires a lot of manpower and electricity.

[0037] Therefore, this embodiment provides a roof expansion bolt auxiliary installation device, which can install and fix the expansion bolts to the roof on the ground without setting up scaffolding or using a lifting vehicle. The installation is convenient and unnecessary consumption can be saved.

[0038] Specifically, see Figure 1 and Figure 2, a roof expansion bolt auxiliary installation device provided by the present embodiment includes an electric wrench socket head 1, a connecting pipe 2 and a handle 3, wherein one end of the connecting pipe 2 is connected to the bottom of the electric wrench socket head 1, and the other end of the connecting pipe 2 is provided with a handle 3. When installing the expansion bolt 10, the nut of the expansion bolt 10 is clamped on the end of the electric wrench socket head 1 away from the connecting pipe 2. The staff holds the connecting pipe 2 to insert the expansion bolt 10 into the expansion bolt 10 hole reserved in the roof, pushes up the expansion bolt 10 until the expansion bolt 10 reaches the required depth, rotates the handle 3, tightens the expansion bolt 10 in the expansion bolt 10 hole, pulls down the connecting pipe 2, the nut of the expansion bolt 10 is separated from the electric wrench socket head 1, and the next expansion bolt 10 is fixedly installed. The operation is simple and convenient.

[0039] It should be noted that the electric wrench socket head 1 is one of the accessories of the electric wrench, and a connecting hole is provided on the upper side thereof, and the nut of the bolt is clamped in the connecting hole. The rotation of the electric wrench socket head 1 drives the bolt to rotate synchronously, thus playing the role of a wrench.

[0040] Preferably, in this embodiment, the electric wrench socket head 1 is a cylindrical structure, the nut of the expansion bolt 10 circumferentially abuts against the inner wall of the electric wrench socket head 1 , and the rod of the expansion bolt 10 extends out of the electric wrench socket head 1 .

[0041] For example, the connecting pipe 2 is a tubular structure to reduce the overall weight of the device, meet the lightweight requirements, and facilitate operation by staff.

[0042] It should be noted that the length of the connecting pipe 2 is adjustable, specifically, it is adjusted according to the height of the top plate.

[0043] By way of example, the present embodiment provides a height adjustment structure of a connecting tube 2, wherein the connecting tube 2 is formed by a first connecting tube 2 and a second connecting tube 2. Specifically, the outer diameter of the first connecting tube 2 is smaller than the inner diameter of the second connecting tube 2, and the first connecting tube 2 is inserted into the interior of the second connecting tube 2. Furthermore, a plurality of first connecting holes are evenly spaced along the circumference of the first connecting tube 2 along its length direction, and correspondingly, a plurality of second connecting holes are evenly spaced along the circumference of the second connecting tube 2 along its length direction. The length of the first connecting tube 2 extending into the second connecting tube 2 is adjusted until it matches the height of the top plate, and then a plurality of bolts are used to pass through the second connecting holes along the circumference of the second connecting tube 2 one by one, and are correspondingly screwed to the first connecting holes along the circumference of the first connecting tube 2 to fix the first connecting tube 2 and the second connecting tube 2.

[0044] Optionally, the first connecting pipe 2 and the second connecting pipe 2 are both made of galvanized steel pipes, which have high structural strength and prevent bending.

[0045] Optionally, the top of the first connecting tube 2 is circumferentially welded to the bottom of the electric wrench socket head 1. Preferably, the top of the first connecting tube 2 is fully welded to the bottom of the electric wrench socket head 1 for a firm connection to prevent the first connecting tube 2 from separating from the electric wrench socket head 1 due to excessive torque.

[0046] Preferably, the edge of the first connecting tube 2 is circumferentially flush with the bottom edge of the electric wrench socket head 1 , so as to achieve full welding of the first connecting tube 2 and the electric wrench socket head 1 .

[0047] Furthermore, in this embodiment, the handle 3 is cylindrical, and is arranged to protrude circumferentially from the connecting tube 2 , so that the staff can hold the handle 3 to rotate the entire structure.

[0048] Preferably, the bottom of the second connecting tube 2 is circumferentially welded to the top of the handle 3 to improve the connection strength and ensure smooth transmission of torque to prevent the second connecting tube 2 from separating from the handle 3 .

[0049] Further preferably, the handle 3 in this embodiment is also made of steel to improve the connection strength between the handle 3 and the second connecting tube 2. In other feasible embodiments, the handle 3 can also be made of other materials and can be welded to the second connecting tube 2.

[0050] In this embodiment, the electric wrench socket head 1, the first connecting tube 2, the second connecting tube 2 and the handle 3 are coaxially arranged to ensure that the expansion bolt 10 moves synchronously with the handle 3 and avoid torque consumption.
