Background
The electric power concrete pole is an electric power pole tower made of concrete and steel bars, is also called as an electric pole and is used for supporting an overhead electric power line; in order to adapt to social development, the investment of the cost of a power distribution network is continuously increased in recent years in the power industry, and the power distribution network is expected to be fully matched with the development of the economic society. In order to avoid unnecessary damage caused by the waste electric poles, the power supply department arranges the waste electric poles left over to be dismantled in batches and comprehensively.
In the traditional construction of demolishing old and useless pole, fixed gin pole is mostly adopted to pull out, falls formula and falls the pole, and the pulling out of concrete pole is a special operation of circuit construction. Before construction, construction design and technical measures of special operation must be made according to conditions such as an electric pole structure, topographic geology, machine tools and equipment. This is a relatively dangerous and rarely used operation and must therefore be conducted by experienced power transmission technicians. The construction scheme should be fully studied before operation, and the construction is carried out according to the specified operation procedure to prevent errors. Before the electric pole is laid down, a construction scheme is determined according to pole shape characteristics and terrain conditions on the basis of field investigation, process design and technical measures are compiled, tools and appliances used for removing the concrete pole are complex in operation process, and the removing difficulty is high.
Meanwhile, in the dismantling process, waste and old wires are still bound on a plurality of electric poles, the wires give certain tension to the electric poles, the corrosion and aging phenomena of the cold-drawn steel bars inside the electric poles due to long-term weathering are generated, but the defects cannot be seen on the surfaces of the electric poles, the cold-drawn steel bars inside the electric poles can be completely corroded, and the electric poles are fixed by the tension. Because the old pole is kept stable by the tension of the upper wire, when workers climb the pole to remove the wire, the pole loses the support of the force of the wire and is in an unsafe working state, the situation of pole breakage is easily caused, and finally the casualties are caused.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a portable electric power concrete pole support, the old and useless electric power concrete pole of mainly used changes rapidly, improves and demolishs the efficiency and the economic benefits who change the operation to ensure the security of operation.
The utility model has the specific technical scheme that the portable electric power concrete pole bracket comprises a fixed lantern ring clamped on a concrete pole, wherein the lower part of the circumference of the fixed lantern ring is hinged with a plurality of telescopic support sleeves and a steel rope locking mechanism; the fixed lantern ring is an openable annular member consisting of two arcs, namely one end of one arc is hinged with one end of the other arc through a hinge, and the other ends of the two arcs are provided with pulleys; the telescopic support sleeve is a telescopic component formed by sleeving a plurality of steel pipes with different diameters together, and is fixed by a sleeve locking bolt when in an extended state; the steel rope locking mechanism comprises pulleys arranged on two sides of the opening of the fixed lantern ring, a tensioning steel rope and a ratchet wheel locking mechanism arranged on the telescopic supporting sleeve.
Furthermore, the telescopic supporting sleeves are uniformly distributed at the lower part of the circumference of the fixed sleeve ring.
Furthermore, one end of the tensioning steel rope is connected to one side of the opening end of the fixed lantern ring, and then is connected to the outer rim of the ratchet wheel locking mechanism after being guided by the pulley on the other side of the opening end of the fixed lantern ring and the pulley on the side.
Furthermore, the ratchet locking mechanism comprises a ratchet mounting seat fixed on the lower pipe wall of the telescopic support sleeve, a ratchet arranged on the ratchet mounting seat and a locking handle; the locking handle is mechanically connected with the ratchet wheel shaft.
Further, the lower extreme of scalable support sleeve pipe articulates there is anti-skidding base.
Further, the lower end of the telescopic supporting sleeve is hinged with a ground anchor which is inserted into the ground for fixing.
The utility model provides a pair of portable electric power concrete pole support beneficial effect lies in: the safety is high, the waste electric pole with the released wires has a stabilizing effect, and a worker is ensured to be in a safe state after the tension of the electric pole is lost and stabilized; the device is simple and portable, has strong maneuverability, is light and easy to install, and is easy for constructors to carry and operate; the device has wide adaptability, can be suitable for removing wires and electric poles in various geographic environments, and particularly can be used for dealing with the conditions that the electric poles are in a soil environment, large vehicles cannot enter or the electric poles are already in the walls of residential houses; the efficiency is high, the method is economical and applicable, the requirement on personnel is less, generally 2-3 people can quickly finish the work of climbing the pole together to dismantle the lead within 15 minutes, and other external supports are not required; when the pole is in low-lying, slope department and needs to carry out the bank protection to it and handle, can use this concrete pole support to its temporary fixation.
