Abstract
Disclosed is a multifunctional hoisting support frame which is installed on an electric transmission line pole tower. The multifunctional hoisting support frame is characterized by being a skeleton frame which is composed of a horizontal cross beam and two inclined rods and is in an approximate isosceles triangle shape. Upper ends of the inclined rods are fixed on tension sleeves which are installed at the upper end and the lower end of the horizontal cross beam, and the tension sleeves are in approximate semicircle shapes and are provided with assembling holes. Limiting plates are installed on the tension sleeves, hooks are installed on outer surfaces of the tension sleeves, and fixed pulleys are respectively installed at two ends of the cross beam. Due to the fact that the multifunctional hoisting support frame is installed at the top end of a pole tower and is kept away from working staff, operation space of the working staff is enlarged, and the multifunctional hoisting support frame is beneficial to hoisting heavy and long hardware fittings. According to the multifunctional hoisting support frame, the design with the pulleys on two sides is adopted, so that a hoisted object is enabled to bear force with two points, and labor intensity of the working staff is relieved. The multifunctional hoisting support frame is simple in structure, convenient to use, labor-saving, resource-saving and capable of improving working efficiency.
Description
Technical field
The invention belongs to power distribution circuit technical field of construction, particularly fitting and hoisting bracket used when transmitting the electric power material on electric force pole tower.
Background technology
Panjin electric company introduced the swallow-wing cross-arm in 2007. the electric power material equipment that composite insulator etc. are novel. and a large amount of applying in the middle of equipment, uses original utensil installation swallow-wing cross-arm, waste time and energy.
Summary of the invention
Face novel swallow-wing cross-arm mounting process complexity in order to have solved power system, the difficult problem of length consuming time proposes following technical scheme.
A kind of multi-functional lifting support that is arranged on electric power line pole tower, its special character is that it is comprised of horizontal gird and two braces the framework that is similar to isosceles triangle, the upper end of every brace is fixed on the horizontal gird upper and lower end is installed pilot hole on its of approximate half-circular cranse, mounting limit plate above cranse, the external surface of cranse is installed hook, at the two ends of crossbeam, fixed pulley is installed respectively.The height of cranse is 200MM.
For the ease of will this multi-functional lifting support being arranged on the top of electric force pole tower, make crossbeam into scalable architecture, be that crossbeam is comprised of intermediate transverse girder and two side crossbeams, two slots are arranged on intermediate transverse girder, on every side crossbeam, through hole is arranged, intermediate transverse girder mutually overlaps afterwards with two side crossbeams and is connected with bolt, at the free end of every side crossbeam, fixed pulley is installed, and the upper end of every brace is separately fixed on the side crossbeam.
When using this multi-functional lifting support lifting material, at first it is arranged on the shaft tower top of concrete bar or rod, promotes simultaneously material by two pulleys, be raised like this thing stress equalization.Use this multi-functional lifting support to lift to need on shaft tower any large-scale gold utensil and the material installed.
The present invention has following advantage
Because this multi-functional lifting support is arranged on the shaft tower top, avoided the operating personnel, increased operating personnel's working space, be convenient to lift heavier, long gold utensil.Simultaneously the cranse height of multi-functional lifting support, be the cranse bottom surface be 200MM far from the distance of head of mast, just in time meet the required distance on the cross arm of tower stipulated in the electric power installation process rules and shaft tower top, dodged the installation site of the attached gold utensil of shaft tower fully.This multi-functional lifting support adopts the design of two side rollers, has avoided when usually using the single-sheaved block transmission, and some colligations are passed that thing causes is subjected to force unbalance and not easily detachable problem, has alleviated operating personnel's labour intensity.Outside the cranse of multi-functional lifting support, two hooks have been installed, the wire of being convenient to like this will temporarily dismantle when changing cross-arm or insulator is placed on hook.This multi-functional lifting supporting structure is simple, easy to use, uses manpower and material resources sparingly, and increases work efficiency.
Description of drawings
Fig. 1 is the structural representation of embodiment 1, and Fig. 2 is partial enlarged drawing A, and Fig. 3 is the structural representation of embodiment 2, and Fig. 4 is the front view of the intermediate transverse girder 6.2 in embodiment 2, and Fig. 5 is the top view of the intermediate transverse girder 6.2 in embodiment 2.
The specific embodiment
A kind of multi-functional lifting support that is arranged on electric power line pole tower, it is comprised of horizontal gird 6 and two braces 7 framework that is similar to isosceles triangle, the upper end of every brace 7 is welded on the cranse 3 of horizontal gird 6 upper and lower end welding approximate half-circular, and the two ends bent outward of cranse 3 is converted into the department of assembly which is provided with pilot hole 3.1.Horizontal limiting plate 4 is installed above cranse 3.The external surface of cranse 3 is installed hook 1, at the two ends of crossbeam 6, fixed pulley 5 is installed respectively.The height of cranse 3 is 200MM.
When should multi-functional lifting support being arranged on shaft tower, limiting plate 4 just in time be stuck in the top of shaft tower, to guarantee that cranse 3 is in the head of mast all the time.
When using this multi-functional lifting support, first climb up the shaft tower top by operation personnel, with transmitting rope, hoisting bracket is carried shaft tower top, then the cranse 3 with multi-functional lifting support is sleeved on the head of mast, insert in the pilot hole 3.1 of cranses 3 with the first bolt 2 and tighten, should multi-functional lifting support being arranged on the shaft tower top.Then penetrate respectively rope in the fixed pulley 5 at support two ends, personnel control is drawn by ground in rope one termination, and the other end ties up to and is raised on thing.
Because the crossbeam in embodiment 1 is a whole plate, in the incomplete situation of coincideing in the space between two cranses 3 and head of mast, when this multi-functional lifting support of installation is tightened the first bolt 2, can be very painstaking, even can't install.Therefore embodiment 2 is proposed.Its difference from Example 1 is that crossbeam 6 is made into can telescopic structure, and namely crossbeam 6 is comprised of intermediate transverse girder 6.2 and two side crossbeams 6.1.Two slots 6.21 are arranged on intermediate transverse girder 6.2, a through hole is arranged on side crossbeam 6.1, intermediate transverse girder 6.2 and two side crossbeams 6.1 overlap mutually, pass the slot 6.21 of intermediate transverse girder 6.2 and the through hole on side crossbeam 6.1 with the second bolt 8, intermediate transverse girder 6.2 and side crossbeam 6.1 are linked into an integrated entity.Can be along the relative changing of the relative positions of slot 6.21 between intermediate transverse girder 6.2 and two side crossbeams 6.1, namely the length of crossbeam 6 is adjustable, is convenient to like this installation of this multi-functional lifting support.The free end of two side crossbeams 6.1 is installed respectively and is welded respectively brace 7 below 5, two side crossbeams 6.1 of fixed pulley.
Before installing, the second bolt 8 is unclamped, allow and be in the state that can relatively move between intermediate transverse girder 6.2 and side crossbeam 6.1, at this moment cranse 3 is sleeved on the top of shaft tower, first tighten the first bolt 2, make cranse 3 fixing, and then tighten the second bolt 8, lock intermediate transverse girder 6.2 and two side crossbeams 6.1.
