Description

Technical Field

[0001] This utility model relates to the field of tunnel electromechanical system technology, specifically a movable support arm for tunnel cable tray installation. Background Technology

[0002] In actual construction, unevenness of the tunnel cable tray support arms results in a poor visual appearance of the cable tray's linearity in the tunnel electromechanical system. According to the design drawings, the traditional cable tray support construction process requires determining the installation position, installing the support arm base, then the support arm itself, and finally the cable tray. However, due to uneven tunnel walls and the lack of adjustment mechanisms, the traditional cable tray support arms, being fixed, can shift at the base angle, causing unevenness in height and angle. This leads to an unsightly linear appearance of the tunnel cable tray, affecting project acceptance. Furthermore, the installation process for cable tray support arms in the current tunnel electromechanical system is cumbersome, slows down construction, and is further hampered by uneven tunnel walls, resulting in an unsightly linear appearance of the tunnel cable tray. Utility Model Content

[0003] The purpose of this utility model is to provide a movable support arm for the installation of cable trays in tunnels. By setting up a support arm base, connecting plate, channel steel support arm, support arm seat, and support arm, it solves the problem that due to uneven tunnel inner wall pouring, traditional cable tray support arms are fixed and lack adjustment devices, resulting in the angle deviation of the support arm base, causing uneven support arm height and angle, which in turn makes the tunnel cable tray linear and unsightly, affecting project acceptance. In addition, the current installation process of cable tray support arms in tunnel electromechanical systems is cumbersome, the construction progress is slow, and the linear and unsightly tunnel cable trays are affected by uneven tunnel inner walls.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a movable support arm for installation of cable trays in tunnels, including a support arm base, a connecting plate welded to the surface of the support arm base, a round hole and a semi-circular waist-shaped hole on the surface of the connecting plate, an A bolt inserted into the round hole, a channel steel support arm rotatably connected to the round hole through the A bolt, A vertical waist-shaped holes on both sides of the channel steel support arm, B bolts for fixing the support arm base inserted into the A vertical waist-shaped holes, and a support arm fixedly connected to one side of the support arm base.

[0005] Preferably, a reinforcing rib is welded between the support arm base and the connecting plate, and B vertical waist-shaped holes and B horizontal waist-shaped holes are respectively opened at both ends of the surface of the support arm base, and expansion bolts are inserted into the interior of both the B vertical waist-shaped holes and the B horizontal waist-shaped holes.

[0006] Preferably, both ends of the inner wall of the channel steel support arm are provided with C-shaped vertical waist-shaped holes and circular grooves, and the A bolt is inserted into the C-shaped vertical waist-shaped holes.

[0007] Preferably, a C-bolt is inserted into the inside of the circular groove, and the circular groove slides with the semi-circular waist-shaped hole through the C-bolt.

[0008] Preferably, the top and bottom walls of one side of the support arm are respectively provided with a horizontal waist-shaped hole (D) and a vertical waist-shaped hole (D), and the B bolt is inserted into the interior of the horizontal waist-shaped hole (D) and the vertical waist-shaped hole (D).

[0009] Preferably, one end of the support arm is fixedly connected to an anti-detachment inclined block.

[0010] This utility model provides a movable support arm for installing cable trays in tunnels, which has the following advantages:

[0011] During use, the equipment is pre-assembled and connected before being installed on the top of the tunnel using expansion bolts, thereby improving the installation speed and construction progress. At the same time, the angle of the channel steel support arm can be adjusted through the semi-circular waist-shaped holes to keep it vertical. With the help of various vertical and horizontal waist-shaped holes, the position and angle of the equipment can be adjusted after installation, thus avoiding the situation of misalignment and unevenness of the equipment after installation due to uneven tunnel pouring, greatly improving the aesthetics, while keeping the equipment horizontally supported and the support arm under balanced force.

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a movable support arm for installation of cable trays in tunnels, including a support arm base 1. A connecting plate 2 is welded to the surface of the support arm base 1. The surface of the connecting plate 2 has a round hole 3 and a semi-circular waist-shaped hole 4. An A bolt 5 is inserted into the round hole 3. A channel steel support arm 6 is rotatably connected to the round hole 3 through the A bolt 5. The connection between the round hole 3 and the channel steel support arm 6 through the A bolt 5 allows the channel steel support arm 6 to rotate around the round hole 3, thereby facilitating the adjustment of the angle of the channel steel support arm 6 after installation and keeping the equipment balanced after installation. A vertical waist-shaped hole 7 is opened on both sides of the channel steel support arm 6. A B bolt 9 for fixing the support arm seat 8 is inserted into the A vertical waist-shaped hole 7. A support arm 10 is fixedly connected to one side of the support arm seat 8. After the support arm seat 8 is installed through the A vertical waist-shaped hole 7, it can be adjusted up and down to keep each support arm 10 horizontal and level.

[0022] A reinforcing rib is welded between the support arm base 1 and the connecting plate 2. The two ends of the surface of the support arm base 1 are respectively provided with a vertical waist-shaped hole 11 and a horizontal waist-shaped hole 12. Expansion bolts 13 are inserted into the interior of both the vertical waist-shaped hole 11 and the horizontal waist-shaped hole 12.

[0023] When fixing the support base 1 with expansion bolts 13, the support base 1 can be finely adjusted through the B vertical waist-shaped hole 11 and B horizontal waist-shaped hole 12 on its surface to keep it flush with other installed equipment, and also avoid the situation of difficulty in alignment caused by uneven tunnel walls.

[0024] Both ends of the inner wall of the channel steel support arm 6 are provided with C vertical waist-shaped holes 14 and circular grooves 15. A bolt 5 is inserted into the inside of the C vertical waist-shaped hole 14, and C bolt 16 is inserted into the inside of the circular groove 15. The circular groove 15 slides with the semi-circular waist-shaped hole 4 through the C bolt 16.

[0025] The C-shaped vertical waist hole 14 provides redundant space for vertical adjustment of the channel steel support arm 6, making the adjustment more flexible and reducing the workload of personnel.

[0026] The top and bottom walls of one side of the support arm 8 are respectively provided with a horizontal waist-shaped hole 17 and a vertical waist-shaped hole 18, and a bolt 9 is inserted into the interior of the horizontal waist-shaped hole 17 and the vertical waist-shaped hole 18.

[0027] By setting the horizontal waist-shaped hole 17 and the vertical waist-shaped hole 18, the position and angle of the bracket seat 8 can be finely adjusted during installation, so as to keep the brackets 10 aligned.

[0028] One end of the support arm 10 is fixedly connected to an anti-detachment inclined block 19. With the setting of the anti-detachment inclined block 19, after the cable tray is installed, there is no need to set fixing bolts to fix the tunnel cable tray, which reduces the workload of personnel.

[0029] Specifically, the movable support arm used for tunnel cable tray installation operates as follows: During use, after pre-assembling and connecting the equipment, it is installed on the tunnel roof using expansion bolts 13, thereby improving installation speed and construction progress. Simultaneously, the angle of the channel steel support arm 6 can be adjusted through the semi-circular waist-shaped holes 4 to maintain its verticality. With the help of the various vertical and horizontal waist-shaped holes, the position and angle of the equipment can be adjusted after installation, thus avoiding misalignment and unevenness caused by uneven tunnel pouring, greatly improving aesthetics. It also ensures the equipment maintains horizontal support and the support arm 10 is under balanced force.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
