Description

Technical Field

[0001] This invention relates to the field of pole reinforcement technology, specifically to a flange pole with a butt-joint reinforcement device. Background Technology

[0002] Flange poles are a type of support structure widely used in power, communications and other fields. They are mainly composed of a prestressed concrete pole body and steel flange connectors. Flange poles have been widely used in high-voltage transmission lines, communication base stations, wind power projects and other scenarios. Especially in areas with harsh environments or limited line corridors, their stability and corrosion resistance ensure the reliable operation of power infrastructure.

[0003] Flanges may experience deformation, corrosion, or even tilting due to limited structural strength, external forces, and environmental corrosion during long-term use. Therefore, it is necessary to install reinforcement devices to improve the stability of the poles and extend their service life.

[0004] Chinese Patent Publication No. CN218438566U discloses a composite pole with flange connections. The pole includes pole segments with flanges at both ends. Fixing assemblies for reinforcing the corresponding flanges are fitted at both ends of the pole segment. The fixing assemblies are detachably mounted on the pole segment. Each fixing assembly includes a fixing member and a locking member fitted onto the pole segment. The fixing member is used to compress and reinforce the flanges, while the locking member is used to fix the fixing member to the pole segment, thus reinforcing the flanges. This structure allows the fixing assemblies to increase the vertical strength of the flanges, thereby improving the stability of the flange connection.

[0005] However, when installing the composite pole with flange connection in the above technical solution, the assembled locking parts need to be screwed onto the fixing parts to complete the reinforcement work. However, during the screwing process, it is necessary to overcome the elastic force of the tensioning part of the fixing parts. The diameter and thickness of the fixing parts that can wrap around the pole and undertake the reinforcement task are generally large, and the installation position is in the air, making it inconvenient for construction personnel to tighten and fix the locking parts, making the reinforcement work quite difficult. Summary of the Invention

[0006] The purpose of this invention is to provide a flange pole with a butt-joint reinforcement device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A flanged utility pole with a butt-joint reinforcement device is provided. The flanged utility pole includes a first utility pole and a second utility pole, which are connected by a flange. The reinforcement device is disposed at the flange and includes:

[0009] An inner reinforcement assembly, comprising an inner sleeve covering the flange and a shifting and locking mechanism disposed on the inner sleeve;

[0010] An outer reinforcement assembly, comprising an outer sleeve with its two ends respectively fitted onto pole one and pole two, and a second shifting lock mechanism disposed on the outer sleeve;

[0011] The locking assembly includes a locking head disposed on the first and second moving lock mechanisms, and a pull lock mechanism disposed on the ground and connected to the locking head. Rotating the pull lock mechanism causes the locking head to press against the first and second moving lock mechanisms, causing the first moving lock mechanism to press and fix the inner sleeve, and causing the second moving lock mechanism to open outward and fit tightly against the first or second pole, thereby fixing the outer sleeve.

[0012] Preferably, the inner sleeve includes symmetrically arranged inner semi-encasing plates, the inner semi-encasing plates including a flange encasing plate that matches the shape of the flange, a pole encasing plate disposed at both ends of the flange encasing plate and respectively attached to pole one or pole two, an inner mating lug disposed on the pole encasing plate, and a locking groove formed on the pole encasing plate.

[0013] Preferably, the moving lock mechanism includes a rod-attaching plate disposed in the locking groove, a rod-attaching rubber pad disposed on the rod-attaching plate, an inner inclined panel disposed on the rod-attaching plate, a pressing arc plate disposed on the inner inclined panel, and a pressing rubber pad disposed on the pressing arc plate.

[0014] Preferably, the outer sleeve includes symmetrically arranged fixing frames, the fixing frames including supporting folding plates, arc plates disposed at both ends of the supporting folding plates and respectively attached to the first pole and the second pole, outer mating lugs disposed on the arc plates, and baffles disposed between the supporting folding plates.

[0015] Preferably, the inner mating ears of the two inner half-covering plates are attached together and fixed with bolts, and the outer mating ears of the two fixing brackets are attached together and fixed with bolts.

[0016] Preferably, the rod plate is provided with a positioning plate, one end of the positioning plate is provided with a slot, and the other end of the positioning plate is provided with a positioning groove, the positioning groove being used to limit the position of the arc plate.

[0017] Preferably, the second shifting and locking mechanism includes a rotating roller inserted into the arc plate, an arc-shaped pressure plate disposed on the rotating roller, an outer expansion plate disposed on the rotating roller, and an outer inclined plate disposed on the outer expansion plate.

[0018] Preferably, the locking head has locking oblique grooves at both ends that respectively cooperate with the outer oblique panel and the inner oblique panel.

[0019] Preferably, the zipper mechanism includes a bracket mounted on the ground, a threaded rod mounted on the bracket, a rotating groove at the end of the threaded rod, a rotating pull block mounted in the rotating groove, a pulley mounted on the bracket, and a steel cable with one end mounted on the rotating pull block and passing around the pulley to connect with the locking head.

[0020] Preferably, rotating the threaded rod causes it to pull the steel cable, which in turn causes the locking head to push the rubber pad against pole one or pole two and to press the rubber pad against the pole-covering plate. The locking head also pushes the outer plate to open outward, causing the arc-shaped pressure plate to press against pole one and pole two.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention improves the reinforcement effect through the design of an inner and outer sleeve, using a double-layered reinforcement structure. With the locking head, outer and inner inclined panels, the inner and outer sleeves can be quickly and simultaneously fixed by pulling down the locking head, making operation convenient. The zipper mechanism allows users to fix the inner and outer sleeves from the ground, making the operation simple and safe. Attached Figure Description
