Description

Technical Field

[0001] The invention relates to the field of communication lighting facilities, and in particular to a steel guide rail pole and a method for installing pole external equipment. Background Art

[0002] With the rapid urbanization process in my country, street lamps are no longer limited to lighting functions. Various external devices such as cameras, LED lights, communication devices or billboards are often installed on the poles 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 poles are gradually increasing. Conventionally, the following are installed on poles: Fig.30 The "C"-shaped steel rail shown is used to install external equipment. Under the action of lateral wind load, the external equipment is prone to shaking, resulting in a gap between the external equipment and the "C"-shaped steel rail, which in turn affects the stability of the connection between the external equipment and the steel rail. Aluminum alloy rails are installed on the poles to install external equipment. The bearing capacity of aluminum alloy rails is weak, and there is a risk of falling for external equipment with heavy installation weight.

[0003] In summary, there is an urgent need for a technical solution to solve the technical problem that the aluminum alloy guide rail on the pole body has a weak bearing capacity and there is a risk of falling when installing heavier external equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a steel guide rail pole and a pole external equipment installation method to address the problem that the aluminum alloy guide rail on the existing pole body has weak bearing capacity and there is a risk of falling when installing heavier external equipment.

[0006] A steel guide rail pole comprises a pole body, on the side wall of which at least one group of steel guide rails is welded, each group of the steel guide rails forms a slot with the side wall of the pole body, and a first equipment connection device is installed in the slot.

[0007] The steel guide rail has high strength and strong load-bearing capacity. The steel guide rail is welded to the side wall of the pole body. The steel guide rail and the side wall of the pole body form a slot. The cable of the external device is arranged in the slot. The slot is also used to install the first device connection device. It has good stability. Compared with arranging aluminum alloy guide rails on the pole body to install external devices, it can improve the ability to bear the weight of external devices and solve the problem that the aluminum alloy guide rails on the existing pole body have weak load-bearing capacity and there is a risk of falling when installing heavier external devices.

[0008] Preferably, the first device connection device comprises a special-shaped bolt fastener and an external device connection member; the external device connection member is detachably connected to the slot via the special-shaped bolt fastener, so as to facilitate installation and disassembly of the external device connection member at the construction site.

[0009] Preferably, the special-shaped bolt fastener comprises a special-shaped screw and a first nut, one end of the special-shaped screw is provided with a hook wedge portion, and the hook wedge portion matches the inner side wall of the steel guide rail. The special-shaped bolt fastener is installed in the slot through the hook wedge portion, and the hook wedge portion matches the inner side wall of the steel guide rail, which is conducive to improving the stability of the installation of the special-shaped screw and the slot.

[0010] Preferably, the special-shaped screw is further provided with a limiting part, the limiting part and the hook wedge part are located at one end of the special-shaped screw, and the limiting part can abut against the bottom of the slot, thereby generating a pre-tightening force for positioning the special-shaped screw relative to the steel guide rail. The limiting part abuts against the bottom of the slot, generating a pre-tightening force that can abut and position the hook wedge part against the inner wall of the steel guide rail, preventing the special-shaped screw from moving along the slot under the action of gravity and falling, making it convenient for operators to install external device connectors on the special-shaped screw.

[0011] Preferably, the limiting portion includes a limiting block, the limiting block is arranged at one side of the hook wedge portion, the limiting block is provided with a first screw hole penetrating therethrough, a stud is arranged in the first screw hole, and the stud is threadedly connected to the first screw hole. The stud is threadedly connected to the first screw hole, the stud moves along the axial direction of the first screw hole, one end of the stud abuts against the bottom of the slot, and the reaction force of the bottom of the slot on the stud can generate a pre-tightening force through the limiting block to make the hook wedge portion abut against the inner wall of the slot, thereby achieving the purpose of positioning the special-shaped screw in the slot.

When the first contact portion and the second contact portion contact both sides of the protrusion at the same time, a gap is formed between the profile and the protrusion. Under the action of a lateral external force, the hook wedge portion of the special-shaped screw rod is the main force-bearing portion, and the contact portion between the first contact portion and the slot and the contact portion between the second contact portion and the slot are both prone to deformation. The gap between the profile and the inner wall of the slot forms an elastic deformation space for the hook wedge portion, thereby forming a pre-tensioning force on the hook wedge portion relative to the slot. Under the action of the pre-tensioning force, the hook wedge portion has the effect of reducing the rigidity of the connection between the hook wedge portion and the slot, preventing the special-shaped screw rod from loosening, and enhancing the stability of the installation of the first equipment connection device.

[0084] The first device connection device 4 includes a special-shaped bolt fastener 4a and an external device connection member 4b; the external device connection member 4a is detachably connected to the slot 2a via the special-shaped bolt fastener 4a, so as to facilitate the installation and removal of the external device connection member 4b.

[0085] The special-shaped bolt fastener 4a includes a special-shaped screw 4a1 and a first nut 4a2, wherein the first nut 4a2 is adapted to the rod column of the special-shaped screw 4a1, and a hook wedge portion 4a3 is provided at one end of the special-shaped screw 4a1, wherein the hook wedge portion 4a3 matches the inner side wall of the slot 2a, which is beneficial to improving the stability of the installation of the special-shaped screw 4a1 and the slot 2a, and a limiting portion 4a4 is further provided on the special-shaped screw 4a1, 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 first screw hole 4a penetrating therethrough 41, a stud 4a42 is provided in the first screw hole 4a41, and the stud 4a42 is threadedly connected with the first screw hole 4a41. By rotating the stud 4a42 along the first screw hole 4a41, one end of the stud 4a42 abuts against the bottom of the slot 2a. The reaction force of the bottom of the slot 2a 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 2a, thereby achieving the purpose of positioning the special-shaped screw 4a1 in the slot 2a, preventing the special-shaped screw 4a1 from moving and falling along the slot 2a under the action of gravity, and facilitating the operator to install the external device connector 4b on the special-shaped screw 4a1.

The contact portion between the first contact portion 4a31 and the slot 2a and the contact portion between the second contact portion 4a32 and the slot 2a 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 2a, thereby forming a pre-tensioning force on the hook wedge portion 4a3 relative to the slot 2a. Under the action of the pre-tensioning force, the rigidity of the connection between the hook wedge portion 4a3 and the slot 2a is reduced, thereby preventing the special-shaped screw 4a1 from loosening.
