Description

The tower crane type pole

Technical field

The utility model is applied to the upright iron tower construction of transmission line of electricity group.

Background technology

The transmission line of electricity group is found iron tower; All be to rely on pole to stand in the iron tower center as supporting the lift heavy operation; Stand and the lift heavy of pole all need many unrestrained wind (steel wire backguy) to grasp in four angular direction and hanging piece both sides, not only need drop into and dote on the purchase of big fund, its manpower transport and putting to good use; The excavation ground anchor pit carries out the fixing construction operation all will expend huge material and manpower, increases the weight of the enterprise construction cost undoubtedly and brings business risk.For this reason, above-mentioned insoluble difficulty is evaded in the crane gear input construction that the research invention is suitable for, and to improve the construction productivity effect, is that the public presses for solution.China's utility application, application number 201120462182.6, name is called " a kind of construction line tower is with telescopic serial pole "; A kind of required crane gear is provided; The scheme of this equipment be " a kind of construction line tower comprises one group of expansion link with telescopic serial pole, form by an outer pole and the interior pole that overlaps in the pole outside; guiding and lifting appliance are arranged between outer pole and the interior pole; pulley is equipped with at the top of interior pole, and a pull rope passes pulley and draws from the expansion link interior lower end, inside and outside pole through rope with link to each other building tower leg ".This equipment has solved subproblem, but improves the said equipment, to improve its function, is that people constantly pursue.

The utility model content

The purpose of the utility model is to provide a kind of can overcome the known technology shortcoming, does not beat unrestrained wind, does not dig ground anchor pit, relies on the half body of the tower of building up; Make lifting gear with Gao Suisheng; Practice thrift this partly labour and a large amount of wire rope, tower crane type pole easy to use, with low cost.

For realizing above-mentioned purpose, the scheme of the utility model is: a kind of tower crane type pole, and pole-climbing is connected to form by the short pole-climbing of more piece; The pole-climbing top has a cross-arm to be connected with vertical mode with pole-climbing; The a pair of roller that is connected by pulley spindle of rail support is arranged on the cross-arm, and the device that has the control pulley spindle to move, the pulley groove on the pulley hold a stay cord that is connected with capstan winch and promote weight; Said pole-climbing by one group of backguy that comprises the waist hoop be connected building the line tower, be provided with the pole-climbing lifting appliance in the pole-climbing bottom.

Adopt such scheme can solve the problem that known technology exists preferably, realized the purpose of the utility model.

The specific embodiment

Part body of the tower 1 as shown in Figure 1, as to form in the line tower installation process, body of the tower 1 will upwards develop then will be by means of the tower crane type pole-climbing of this programme design, and said pole-climbing is made up of the short pole-climbing 2 of more piece; The length of short pole-climbing 2 is about 4.25 meters, and its cross section is a rectangle, and end face is welded with flange 4, connects with bolt through the screw on the flange; Nut makes progress, general utility wrench easy to use, and the upper end of combination pole-climbing is provided with a cross-arm 3, and it is long to be 5-6 rice; Cross-arm one end is connected with hinge with the pole-climbing end, and state is not as shown in Figure 3 when using, when being connected with pole-climbing is vertical; The other end is with stay cord 5 pull-ups, and the other end of stay cord 5 is connected with the pole-climbing top, forms a triangular support.

The pole-climbing 2 that is combined into is provided with waist hoop 6 two positions, porosely in the middle of the said waist hoop 6 cooperates with around the pole-climbing, and propping up of stretching out porosely on the sheet 7 fixed one section steel cable, this steel cable with link to each other building the line tower, as shown in Figure 4.

Cross-arm has a pair of relative channel-section steel 8; The top of channel-section steel connects a crossbeam, and the bottom of channel-section steel forms guide rail, supports a pair roller 10 of pulley spindle 9; Two pair rollers form scooter; It is stable to be convenient to pulley, and pulley spindle cooperates with roller is movable, has a shaft clip 11 to link to each other with the device that a control pulley spindle moves on the pulley spindle.As shown in Figure 5.

The device that described control pulley spindle moves is as shown in Figure 6; Comprise along the fixing electric block 12 of an end of the microscler direction of cross-arm; Manual or electronic control all can, it promotes chain 13 and walks around on the sprocket wheel 14 that is located at the cross-arm other end, chain links to each other with shaft clip 11 on the pulley; Moving by cucurbit 12 of pulley spindle controlled like this, and weight just can be delivered to assigned address exactly like this.As shown in Figure 6.

Be provided with the pole-climbing lifting appliance like Fig. 1 in the bottom of pole-climbing.Along with the line tower constantly to aerial extension, pole-climbing also will change the position.At this moment need promote pole-climbing.Said lifting appliance is included on another position of the fixing online tower of an end of building fixing 15, steel cables 16 of a pulley on the line tower, ties up to the bottom of pole-climbing again, walks around pulley 15 again, links to each other with a winch.Start capstan winch like this pole-climbing is risen, two waist hoops flow to transposition, finish changing just to change stay cord; Rise pole then; Again with on the fixing online tower of the steel cable on the waist hoop 6, draw many unrestrained wind ropes 17 in addition from the pole-climbing upper end and fasten on the online tower after putting in place, then pole-climbing will be very firm on reposition.

Be provided with capstan winch room 18 at the pole-climbing bottom position, along with the rising of pole-climbing is suspended in the air, this is for saving the steel cable length of winch.

Adopt this device to bring convenience for construction line tower.At first on the basis, build the partial line tower, establish pole-climbing, utilize waist hoop and other unrestrained wind rope to tie up on the line tower and fix pole-climbing; Hitch cross-arm with fixing steel cable 5 again after utilizing winch pull-up cross-arm, can use this device, lifting line tower mounting material is to assigned address; Utilize lifting appliance rising pole-climbing again after the line tower raises, a section like this line tower is raised, overcome the defective of prior art; Bring easy construction, saved the tower fund of building.
