Description

Technical Field

[0001] The invention relates to the field of communication lighting facilities, and in particular to a steel track pole column resistant to weak current interference and an external equipment installation method. Background Art

[0002] With the increasingly rapid urbanization process in my country, street lamps are no longer limited to the use of lighting functions. Various external devices such as cameras, LED lights, communication devices or billboards are often installed on the pole body according to needs. With the increase in the number and quality of external devices, the requirements for the load-bearing capacity and installation stability of external devices installed on the pole are gradually strengthened. Aluminum alloy rails are installed on the poles to install external devices. The load-bearing capacity of the aluminum alloy rails is weak. For external devices with heavy installation weight, there is a risk of falling. The cables of a large number of external devices are installed on the pole body. The cables include power lines, signal lines, and communication lines for exchanging with other devices or peripheral devices. There are at least 3 wires. These 3 wires are used as round-trip lines to transmit current or signals. Electromagnetic fields are easily generated in the space where the cables are installed to form electromagnetic radiation interference, which affects the transmission function of weak current signals. Exposed cables are prone to aging.

[0003] In summary, there is an urgent need for a technical solution to solve the technical problems of installing aluminum alloy rails on poles, the weak bearing capacity of aluminum alloy rails, the risk of falling when installing heavy external equipment, and the easy generation of electromagnetic radiation interference by centralized installation of cables on the pole body, which affects the weak current signal transmission function in the cable. Summary of the invention

[0007] The steel rail has high strength and strong bearing capacity. The steel rail is welded to the side wall of the pole body. The steel rail and the side wall of the pole body form a slot. The slot is used to arrange the cable of the external device. The slot is also used to install the equipment connection device. It has good stability. Compared with arranging an aluminum alloy guide rail on the pole body to install the external device, the weight bearing capacity of the external device can be improved. A guide rail is arranged on the side wall of the pole body. A single groove along the guide rail direction is arranged on the guide rail. The single groove is used to arrange the cable. When the external device is installed on the pole body, different cables of the external device are arranged in the single groove and the slot respectively. Through the separation of the single groove and the slot, the cables are arranged in separate compartments to avoid contact between cables of different devices, thereby reducing the electromagnetic radiation interference formed by the centralized installation of cables and the influence on the weak current transmission signal. The device has a simple structure and solves the technical problems that the centralized installation of cables on the existing pole body is prone to electromagnetic radiation interference, and the existing aluminum alloy guide rail is installed on the pole, the aluminum alloy guide rail has weak bearing capacity, and there is a risk of falling when installing heavier external devices.

The guide rail and the pole body are connected and fixed by inserting rivets or bolts into the connection holes at the relative positions of the guide rail and the side wall of the pole body. By installing a large number of external devices on the guide rail instead of directly drilling holes on the pole body to install the external devices in the conventional way, the number of holes drilled on the pole body can be reduced, thereby avoiding affecting the strength of the pole.

[0012] Preferably, the equipment connection device comprises a special-shaped bolt fastener and an external equipment connection piece; the external equipment connection piece is detachably connected to the slot via the special-shaped bolt fastener, so as to facilitate the installation and removal of the external equipment connection piece at the construction site.

[0093] The special-shaped bolt fastener 4a includes a special-shaped screw 4a1 and a nut 4a2, wherein the nut 4a2 is adapted to the rod column of the special-shaped screw 4a1, and one end of the special-shaped screw 4a1 is provided with a hook wedge portion 4a3, wherein the hook wedge portion 4a3 matches the inner side wall of the slot 8a, which is beneficial to improving the stability of the installation of the special-shaped screw 4a1 and the slot 8a, and the special-shaped screw 4a1 is also provided with a limiting portion 4a4, wherein the limiting portion 4a4 and the hook wedge portion 4a3 are located at one end of the special-shaped screw 4a1 and are arranged at an angle of 90°, and the limiting portion 4a4 includes a limiting block, wherein the limiting block is provided with a screw hole 4a penetrating therethrough. 41, a stud 4a42 is provided in the screw hole 4a41, and the stud 4a42 is threadedly connected with the screw hole 4a41. By rotating the stud 4a42 along the screw hole 4a41, one end of the stud 4a42 abuts against the bottom of the slot 8a. The reaction force of the bottom of the slot 8a on the stud 4a42 can generate a pre-tightening force through the limit block to make the hook wedge part 4a3 abut against the inner wall of the slot 8a, thereby achieving the purpose of positioning the special-shaped screw 4a1 in the slot 8a, preventing the special-shaped screw 4a1 from moving and falling along the slot 8a under the action of gravity, and facilitating the operator to install the external device connector 4b on the special-shaped screw 4a1.

[0094] The hook wedge portion 4a3 is respectively provided with a first contact portion 4a31 and a second contact portion 4a32, the first contact portion 4a31 is in arc surface contact with the card slot 8a, the second contact portion 4a32 is in line contact or point contact with the card slot 8a, the first contact portion 4a31 and the second contact portion 4a32 can contact the inner wall of the card slot 8a at the same time, the first contact portion 4a31 contacts the inner wall of the card slot 8a to form a first clamping force, and the second contact portion 4a32 contacts the inner wall of the card slot 8a to form a second clamping force; the first clamping force along the normal line of the contact surface and the second clamping force along the normal line of the contact surface can intersect to form a wedge-shaped angle, so that the hook wedge portion 4a3 generates a clamping force on the card slot 8a, has good stability, and can effectively reduce the force shaking of the external device connected to the special-shaped screw 4a1, and the hook wedge portion 4a3 is also provided with a profile 4a33, the profile 4a33 is located between the first contact portion 4a31 and the second contact portion 4a32. When the first contact portion 4a31 and the second contact portion 4a32 are in contact with the inner wall of the slot 8a at the same time, a gap is formed between the profile 4a33 and the inner wall of the slot 8a. Under the action of lateral external force, the hook wedge portion 4a3 of the special-shaped screw 4a1 serves as the main force-bearing portion. The contact portion between the first contact portion 4a31 and the slot 8a and the contact portion between the second contact portion 4a32 and the slot 8a are both prone to deformation. A buffer space for elastic deformation of the hook wedge portion 4a3 is formed through the gap between the profile 4a33 and the inner wall of the slot 8a, thereby forming a pre-tensioning force on the hook wedge portion 4a3 relative to the slot 8a. Under the action of the pre-tensioning force, the connection rigidity between the hook wedge portion 4a3 and the slot 8a is reduced, thereby preventing the special-shaped screw 4a1 from loosening.
