Description

Technical Field

[0001] The utility model relates to the field of disassembly of tie rods of anti-collision wall templates, in particular to a tool for safely disassembling and assembling tie rods of anti-collision wall templates. Background Art

[0002] During the construction of the crash wall of the bridge, the disassembly and installation of the crash wall template requires the installation and removal of the tie rod. The nuts on the outside of the tie rod of the crash wall template are located at the high-altitude edge, especially the tie rod nuts at the lower part of the outer side of the template. The installation and removal requires manual high-altitude work using a lifting rope, and high-altitude edge work may cause the operator to fall from a high altitude. Therefore, it is necessary to develop a crash wall template tie rod installation and removal tool to solve the above problem. Utility Model Content

[0003] In order to solve the above-mentioned problems, the utility model provides a tool for safely disassembling and assembling a tie rod of an anti-collision wall formwork.

[0004] The utility model is realized through the following technical solutions:

[0005] A tool for safely disassembling and assembling a tie rod of a collision-proof wall formwork comprises an L-shaped operating sleeve, the bottom end of which is rotatably connected to a nut sleeve for disassembling and assembling a nut of the tie rod, one end of the nut sleeve being fixedly connected to a transmission flexible shaft arranged in the L-shaped operating sleeve, and the other end of the transmission flexible shaft being connected to a driving rotary joint.

[0006] Further optionally, a rotating sleeve is fixed at the bottom end of the L-shaped operating sleeve, a rotating head is rotatably connected inside the rotating sleeve, the outer end of the rotating head is fixedly connected to the nut sleeve, and a rotating socket matching the limiting rod is opened on the other side of the rotating head, and the limiting rod is fixedly connected to the end of the transmission flexible shaft.

[0007] Further optionally, the other end of the transmission flexible shaft extends to the top of the L-shaped operating sleeve, a handle is fixed to the top of the L-shaped operating sleeve, and a mounting hole matching the rotary joint is provided in the handle.

[0008] Further optionally, the length of the nut sleeve is 15-20 cm.

[0009] Further optionally, the L-shaped operating sleeve is a hard metal sleeve.

[0010] Compared with the existing technology, the beneficial effect of the utility model is that the utility model installs a rotating nut sleeve on the L-shaped operating sleeve, and drives the rotation through the internal transmission flexible shaft to achieve the installation and removal of the pull rod, so that the operating personnel do not need to work at high altitude outside the template when installing and removing the pull rod, thereby protecting the personal safety of the operating personnel.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0017] like Figure 1 , 2 As shown, a tool for safely disassembling and assembling the tie rod of the anti-collision wall formwork includes an L-shaped operating sleeve 1, the bottom end of the L-shaped operating sleeve 1 is rotatably connected to a nut sleeve 4 for disassembling and assembling the nut 12 of the tie rod 11, one end of the nut sleeve 4 is fixedly connected to a transmission flexible shaft 7 arranged in the L-shaped operating sleeve 1, and the other end of the transmission flexible shaft 7 is connected to a driving rotary joint 9, which is quickly driven and connected to a hand electric drill through the rotary joint 9.

[0018] like Figure 2 As shown, a rotating sleeve 2 is fixed to the bottom end of the L-shaped operating sleeve 1, and a rotating head 3 is rotatably connected inside the rotating sleeve 2. The rotating sleeve 2 is limited to prevent the rotating head 3 from falling off, thereby ensuring its safety and reliability. The outer end of the rotating head 3 is fixedly connected to the nut sleeve 4, and a rotating socket 5 matching the limiting rod 6 is opened on the other side of the rotating head 3. The nut sleeve 4 is connected to the transmission flexible shaft 7 through the rotating socket 5, and the limiting rod 6 is fixedly connected to the end of the transmission flexible shaft 7.

[0019] like Figure 3 As shown, the other end of the transmission flexible shaft 7 extends to the top of the L-shaped operating sleeve 1, and a handle 8 is fixed to the top of the L-shaped operating sleeve 1. The handle 8 is provided with a mounting hole matching the rotary joint 9.

[0020] The length of the nut sleeve 4 is 15-20cm. Its longer length can better adapt to the exposed screw of the pull rod nut, while also ensuring the moving space for disassembling the nut to prevent it from falling off. The L-shaped operating sleeve 1 is a hard metal sleeve, which has higher strength to avoid bending and damage, and it is more convenient to disassemble the pull rod nut in the air.

[0021] The implementation principle of a tool for safely disassembling and assembling the tie rod of the anti-collision wall formwork in the embodiment of the present application is as follows:

[0022] When the nut 12 of the free-standing tie rod 11 at the lower outer side of the anti-collision wall template 10 is removed (such as Figure 4 As shown in the figure, the operator stands on the bridge deck position inside the crash wall template and holds the handle 8 of the L-shaped operating sleeve 1, extends the nut sleeve 4 at the bottom end of the L-shaped operating sleeve 1 to the outside of the crash wall template 10, and faces the nut 12 of the lower empty tie rod 11, and inserts the nut sleeve 4 into the nut 12;

[0023] Then the operator uses the other hand to use an electric drill 13 with a plug, inserts the plug of the electric drill 13 into the rotary joint 9 inside the handle 8, starts the electric drill 13 to drive the transmission flexible shaft 7 through the rotary joint 9 to drive the rotary head 3 at the bottom, so that the nut sleeve 4 rotates counterclockwise, and the nut 12 is quickly removed; when installing the nut 12, the reverse operation is performed, so that the operator does not have to work at high altitude outside the template when installing and removing the pull rod nut 12, thereby protecting the personal safety of the operator.

[0024] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
