Description

Technical Field

[0001] This application relates to the technical field of steel pipe poles, and particularly to a high-voltage overhead power transmission and transformation steel pipe pole. Background Art

[0002] The power transformation steel pipe pole is a new type of power equipment for erecting power lines in recent years and is an alternative product to traditional cement pole electric wires. The power transformation steel pipe pole is made of steel such as polygonal steel pipes and circular steel pipes, and is treated with anti-corrosion coating by hot-dip galvanizing or hot-spraying zinc (and zinc alloys).

[0003] A cross arm for fixing electric wires is provided on the steel pipe pole. When the steel pipe pole is operating normally, after the steel pipe pole is subjected to the cross arm tension, the bending moment at the connection between the steel pipe pole and the ground is relatively large. Therefore, a support structure for supporting the steel pipe pole is generally provided. The support structure surrounds the steel pipe pole for one week to support the steel pipe pole. However, this support structure occupies a large space, thus reducing the application range of the steel pipe pole in areas with limited space. Summary of the Invention

[0006] A high-voltage overhead power transmission and transformation steel pipe pole includes a bearing platform arranged on the ground, a steel pipe pole arranged on the bearing platform, and a cross arm arranged on the steel pipe pole. It is characterized in that: the direction of the wire tension received by the cross arm is perpendicular to the length direction of the cross arm, a support mechanism for supporting the steel pipe pole is arranged on the bearing platform, and the support mechanism includes:

[0007] A support ring, the support ring is arranged on the bearing platform;

[0008] Two fixing plates, the two fixing plates are arranged on the support ring and on both sides of the axis of the steel pipe pole, and at the same time, both of the two fixing plates extend to the side of the support ring far from the steel pipe pole along the direction perpendicular to the length direction of the cross arm;

[0009] Two support rods, the two support rods are respectively rotatably arranged on the two fixing plates and are inclined upward to be connected with the steel pipe pole and used for supporting the steel pipe pole.

[0010] By adopting the above technical solution, the fixing plate extends to the side far from the steel pipe pole, and the support pole supports and positions the steel pipe pole. Therefore, the two support poles on both sides of the steel pipe pole cooperate to buffer the tensile force received by the steel pipe pole, thus supporting and positioning the steel pipe pole. There is no need to set up a support structure at other angles of the steel pipe pole, so the space occupied by the support structure is reduced, thereby realizing the support of the steel pipe pole and also improving the application range of the steel pipe pole in areas with limited space.

[0011] Optionally, the steel pipe pole is installed on the bearing platform through a connection component, and the connection component includes:

[0012] A fixed disk, which is arranged on the bearing platform and located within the support ring;

[0013] A connecting flange, which is arranged at the bottom end of the steel pipe pole and is snap-fitted into the support ring. The connecting flange is placed on the fixed disk and is provided with mounting holes, and the fixing plate extends to the outside of the bearing platform;

[0014] A connecting screw and a connecting nut. The connecting screw is arranged on the fixed disk and passes through the mounting hole, and the connecting nut is threadedly connected to the connecting screw and abuts against the connecting flange for positioning.

[0015] By adopting the above technical solution, the connecting flange is snap-fitted into the support ring, so that the connecting flange presses against the fixed disk. At the same time, the connecting screw passes through the mounting hole, and then the connecting nut is threadedly connected to the connecting screw, so that the connecting nut abuts tightly against the connecting flange to fix and install the steel pipe pole. At the same time, the connecting flange is snap-fitted into the support ring, thus improving the stability of the steel pipe pole and making the support ring structure compact, thereby reducing the space occupied by the support ring on the bearing platform. Therefore, the fixed installation of the steel pipe pole is realized, and at the same time, the stability of the steel pipe pole and the application range of the steel pipe pole in areas with limited space are also improved.

[0016] Optionally, a guiding groove communicating with the top end of the support ring is provided on the inner side wall of the support ring, and a guiding block that can be snap-fitted into the guiding groove is arranged on the connecting flange. When the guiding block is snap-fitted into the guiding groove, the connecting screw and the mounting hole are aligned.

[0017] By adopting the above technical solution, the guiding block is snap-fitted into the guiding groove to position the connecting flange, so as to facilitate passing the connecting screw through the mounting hole, thus improving the convenience of installing the steel pipe pole.

[0018] Optionally, a bearing ring that abuts against the steel pipe pole is detachably installed on the top end of the support ring. A bearing block is provided on the bearing ring and is inserted and installed into the guide groove and presses against the guide block for positioning. A rotating ring detachably connected to the bearing ring is rotatably provided on the outer side wall of the support ring. The fixing plate is provided on the rotating ring. The support rod is detachably connected to the steel pipe pole through a fixing component. A positioning component for positioning the rotating ring is provided on the support ring.

[0019] By adopting the above technical solution, the bearing ring is placed on the top end of the support ring, so that the bearing block is snap-fitted and installed into the guide groove to fix the bearing ring, and the bearing block presses against the guide block for positioning. At the same time, the bearing ring abuts against the steel pipe pole to position the steel pipe pole, thereby improving the stability of the steel pipe pole. Moreover, the rotating ring fixedly connects the fixing plate, the support rod, the bearing ring and the support ring together, further improving the support effect on the steel pipe pole, and thus further improving the stability of the steel pipe pole. Therefore, while meeting the stability of the steel pipe pole, the space occupied by the support structure can be designed to be reduced, so that while meeting the stability requirements of the steel pipe pole, the application range of the steel pipe pole in areas with limited space can also be increased.

[0020] Unlock the fixing component and the positioning component, then disassemble the rotating ring from the bearing ring, and then the rotating ring can be rotated to adjust the position of the support rod. After the adjustment is completed, connect the rotating ring to the bearing ring, and then lock the fixing component and the positioning component to position the support rod and the rotating ring. Therefore, after the position of the cross arm changes, the position of the support rod can also be adjusted to match the position of the cross arm, further improving the support effect on the steel pipe pole, improving the stability of the steel pipe pole, and at the same time increasing the application range of the steel pipe pole in areas with limited space.

[0021] Optionally, the fixing component includes:

[0022] Two fixing rings, one end of the two fixing rings is rotatably connected together and are respectively rotatably provided on the two support rods and cooperate to clamp the steel pipe pole.

[0024] By adopting the above technical solution, turn the fixing nut away from the fixing ring, and then the rotating ring can be rotated to drive the support rod and the fixing ring to rotate. After the rotation is completed, turn the fixing nut to abut against the fixing ring for positioning to fix the support rod, thereby realizing the positioning of the support rod and the steel pipe pole.

[0025] Optionally, the rotating ring can slide up and down. The positioning component includes:

[0026] A positioning gear, the positioning gear being arranged on the outer side wall of the support ring;

[0027] The positioning ring gear is arranged on the rotating ring and can mesh with the positioning gear and is used to position the rotating ring. At the same time, the upward movement of the rotating ring can drive the positioning ring gear to disengage from the positioning gear.

[0028] By adopting the above technical solution, after the fixing assembly is opened, the rotating ring is pushed to drive the positioning gear ring to move upward and disengage from the positioning gear. At the same time, the support rod moves upward to drive the fixing assembly to move on the steel pipe rod, and then the rotating ring can be rotated. After the rotating ring rotates, the rotating ring moves downward to drive the positioning gear ring to move downward and engage with the positioning gear, thereby preventing the rotating ring and the support rod from rotating, thereby further improving the positioning effect of the support rod and improving the stability of the steel pipe rod.

[0029] Optionally, a positioning block is rotatably mounted on the upper surface of the carrying ring, a carrying rod extending to the positioning block is provided on the rotating ring, and a linkage plate is provided on the carrying rod that abuts against the two side walls opposite to the positioning block, so that the positioning block is driven to rotate together when the rotating ring rotates, and a carrying screw threadedly connected to the positioning block is threaded on the carrying rod.

[0030] When the cam is in the closed position, the gear ring is disengaged from the positioning gear by rotating the supporting plate, and the cam is in the closed position, so that the cam is in the closed position and the gear ring is disengaged from the positioning gear.

After the adjustment is completed, the adjusting component locks the position of the cross arm for positioning, so as to realize the adjustment of the position of the steel pipe pole; meanwhile, the alignment component is used to display the angle of the cross arm, so that the position of the supporting pole can be matched with the position of the cross arm during subsequent adjustment of the position of the supporting pole, thereby further improving the stability of the steel pipe pole.

[0033] Optionally, a plurality of mounting grooves are circumferentially arranged around the axis of the mounting ring on the outer side wall of the mounting ring, and the adjusting component includes:

[0034] An adjusting block, which is slidably arranged on the adjusting ring;

[0035] An adjusting screw rod, which is threadedly connected to the adjusting ring and rotatably connected to the adjusting block. At the same time, when the adjusting block is clamped and installed in the mounting groove, the head of the adjusting screw rod abuts against the adjusting ring for positioning.

[0036] By adopting the above technical solution, turning the adjusting screw rod drives the adjusting block to disengage from the mounting groove, and then the adjusting ring can be rotated to adjust the angle of the cross arm. After the adjustment is completed, turning the adjusting screw rod drives the adjusting block to be clamped and installed into the mounting groove for positioning, so as to realize the adjustment of the angle of the cross arm.

[0037] Optionally, the alignment component includes:

[0038] Two angle lines, which are respectively arranged on the steel pipe pole at the mounting ring and the rotating ring and are respectively used to display the angles of the cross arm and the supporting pole;

Therefore, the position of the supporting pole after adjustment can better adapt to the angle of the cross arm after adjustment, so as to improve the supporting effect on the steel pipe pole and improve the stability of the steel pipe pole.

Then push the bearing screw rod 36 to drive the positioning gear ring 62 to disengage from the positioning gear 61, and then rotate the bearing screw rod 36 to drive the support rod 23 and the fixing plate 22 to rotate. The pointer 82 located on the rotating ring 33 shows the angle. When the angle is the same as the angle of the cross arm 11, stop rotating. The bearing screw rod 36 moves downward to drive the positioning gear ring 62 and the positioning gear 61 to engage, and turn the bearing screw rod 36 to be threadedly connected to the positioning block 16 for positioning.
