Problems solved by technology

[0004] However, during the jacking process of the existing electric holding pole, the crawling claws on the lower side have a small reserved distance from the nearest support block above it, so that the crawling claws have enough space to turn inward without being affected by the support block. Blocking, when the upper and lower claws alternately support the standard section, the standard section will sink for a short distance, resulting in empty travel, which reduces the lifting efficiency and stability

Embodiment 1

[0035] Such as Figure 1 to Figure 3 As shown, a double-arm electric holding pole includes: a tower body 1, a cantilever 2 and a lifting frame 3.

[0036] The tower body 1 includes a plurality of standard sections 4 fixedly connected sequentially along the longitudinal direction, the top of the standard section 4 is installed with a rotary joint seat 6, and the top of the rotary joint seat 6 is installed with an A-type tower 5; the left and right sides of the A-type tower 5 are installed symmetrically The cantilever 2 is horizontally suspended on the tower body 1 by a sling, and the hoist pulley block 7 is installed on the cantilever 2 to erect the pole.

[0037] The inside of the hoisting frame 3 is provided with a frame room for accommodating the standard section 4. Lifting frame 3 is used for raising standard section 4 to empty the assembly space of next standard section below it, until a plurality of standard sections are affixed sequentially along the longitudinal direct...

Embodiment 2

[0046] In this embodiment, a stroke compensation mechanism is added on the basis of Embodiment 1. Before the return mode starts, the first lifting arm 9 has a small reserved distance from the nearest support block 11 above it, so that the first lifting arm 9 has enough The space can be turned inward without being blocked by the support block 11. In order to make the second workbench 14 release the standard joint in the return mode, the first jacking arm 9 can withstand the lower side of the standard joint in time, so that the standard joint does not slide due to the existence of the reserved distance. A stroke compensation mechanism is set on the frame, and the stroke compensation mechanism raises the first workbench 13 for a certain distance, so that the first lifting arm 9 is closely attached to the bottom of the support block 11, so as to realize the handover from the second workbench 14 without empty space Standard section 4, prevent the standard section from slipping.

Embodiment 3

[0051] In this embodiment, on the basis of Embodiment 2, a guiding mechanism for fine-tuning the standard joint 4 is added. The first surrounding seat 8 and the second surrounding seat 15 are equipped with a guiding mechanism for adjusting the standard joint 4 moving upward. Guide along the longitudinal direction to prevent the slight deflection of the standard section 4 during the lifting process and affect the balance and support strength of the tower body.

[0052] The guiding mechanism comprises a supporting beam 26 and a guiding wheel set mounted on the supporting beam 26, and a plurality of supporting beams 26 are respectively welded and fixed on the first surrounding seat 8 and the second surrounding seat 15, and the first surrounding seat 8 and the second surrounding seat The surrounding seats 15 correspond to four sets of guide wheels, and the four sets of guide wheels are close to the four joint columns 10 of the standard section. During the rising process of the stan...

Abstract

The invention provides a double-arm electric holding pole. A tower body of the double-arm electric holding pole comprises a plurality of standard sections which are fixedly connected in the longitudinal direction; a lifting frame is used for lifting the standard section so as to assemble the next standard section below, and a frame chamber for accommodating the standard section is arranged in the lifting frame; a first working platform is installed on the lifting frame and comprises a first surrounding seat and a first jacking arm hinged to the first surrounding base; a support block is fixed to a section column of the standard section; the first jacking arm can turn inwards to abut against the support block; a lifting oil cylinder is mounted on the first working platform, and the lifting oil cylinder can lift or lower a second working platform; the second working platform comprises a second surrounding seat and a second jacking arm hinged to the second surrounding seat, and the lifting frame has a lifting mode and a return mode; in the lifting mode, the lifting oil cylinder lifts the second working platform to enable the second jacking arm to support the support block to lift the standard section upwards; and in the return mode, the first jacking arm turns inwards to temporarily support the support block above the first jacking arm, and the lifting oil cylinder lowers the second working platform. The double-arm electric holding pole is high in lifting efficiency and good in stability.

Description

technical field [0001] The invention belongs to the technical field of engineering equipment, and in particular relates to a double-arm electric holding pole. Background technique [0002] Electric pole holding is a kind of special equipment for vertical poles. It works together with winches, pulleys and wire ropes, and can lift hundreds of tons of electric poles on the spot. The pole can be divided into single-arm pole and double-arm pole according to the number of booms. [0003] For example, the patent with the notification number CN201545635U discloses a double-flat arm holding pole, including a tower body standard section, a hoisting mechanism, an electric control system, a mast, a luffing trolley, a hook, a waist ring, a slewing bearing, an upper support, Flat arm, hoisting wire rope, luffing wire rope, lower support and luffing mechanism. Luffing trolley, the other end of the hoisting wire rope is fixed on the outer end of the flat arm, and the tower body is lifted ...
