Abstract
The utility model relates to an automatic safety unit of a lifting basket for construction, which is composed of a supporting part, a safety part and a swing arm part. The supporting part is fixed to the steel tube brackets on the both sides of the lifting basket for construction, and the safety part and the swing arm part are arranged on the supporting part. When a hoisting rope is strained, the swing arm swings 45 DEG angle to be in stress and drives a mating gear to rotate through a supporting shaft. The tension spring is strained, simultaneously an eccentric braking gear rotates to make the middle space enlarge, and a safety rope is loosened. When the hoisting rope is broken or in the relaxation status, the swing arm part is naturally perpendicular, and the tension spring pulls the mating gear to turn and drives the supporting shaft and a gear shaft to rotate, in order to enable the eccentric braking gear to restore to the initial position to jam the safety rope and make the basket stable and balancing to play the action of automatic safety.
Description
The utility model belongs to the vehicle for construction safety locking motion.
Existing skyscraper basket of work, safety device has various forms, as be with hypervelocity safety lock and manual decline speed-limit device (seeing the Tianjin volume machine ZLD500 of a factory high-rise working finishing hanging basket) and adopt ratchet mechanism realization insurance, add click at the insurance rope sheave back side, by manually stirring the insurance rope sheave, reach insurance purpose (seeing Liaocheng Prefecture, Shandong Province construction engineering corporation construction nacelle device).Though the device of these forms can play certain security insurance effect, under the routine work situation reaction slower, degree of automation is lower, some structure is complicated, with the whole supporting fashionable dress of hanging basket, repair comparatively inconvenient.
The purpose of this utility model just provides a kind of novel building hanging basket safety device, and is simple in structure, easy to install, safe, good reliability, and the degree of automation height is easy to apply.
Task of the present utility model is finished like this: according to the constructional feature of the high-rise operation of building hanging basket, design a kind of building hanging basket automatic safety, comprise support section, the insurance part, the swing arm part, support section is made up of stay bearing plate (1) and pivot shaft (2), the insurance part is by gear wheel shaft (3), engaging gear (4), the off-centre bearing up pulley (5) of stopping, arm-tie (6), extension spring (7), safety rope (9), insurance rope sheave (18) is formed, the swing arm part is by swing arm change gear (10), clamping plate (11), derrick line guide wheel (12), swing arm wheel shaft compositions such as (13), support portion fixes is on building hanging basket both sides steel pipe frames (17), and the swing arm of insurance partial sum partly is installed on the support section.Stay bearing plate (1) is two identical metal sheets, have axis hole in both sides near vertical center line, first metal sheet captiveed joint with hanging basket steel pipe frame (17), be assemblied in the insurance division branch by pivot shaft (2), gear wheel shaft (3) and extension spring set collar (8), second metal sheet covers at insurance division and divides the outside, overlaps fixing again with first metal sheet with screw.Pivot shaft (2) is a long castellated shaft, and an end passes stay bearing plate (1) left side axis hole, and engaging gear (4) and the off-centre bearing up pulley (5) of stopping can be installed, and the other end stretches out outside stay bearing plate (1), can cooperate installation with swing arm change gear (10).Engaging gear (4) and the off-centre bearing up pulley (5) of stopping respectively is two, an engaging gear (4) and off-centre overlapping pivot shaft (2) that is sleeved on of bearing up pulley (5) of stopping is fixed on the part in the stay bearing plate (1), another engaging gear (4) and another off-centre are stopped on the overlapping gear wheel shaft (3) that is sleeved on the interior right side of fixed support plate (1) of bearing up pulley (5), and safety rope (9) is stopped by two off-centre and passed in the space between the bearing up pulley (5).Arm-tie (6) and extension spring (7) respectively are two, and arm-tie (6) is captiveed joint with engaging gear (4) respectively, and the two ends of extension spring (7) are connected with extension spring set collar (8) on the stay bearing plate (1) with arm-tie (6) respectively.Gear wheel shaft (3) is installed in the axis hole on stay bearing plate (1) right side for short castellated shaft, can overlapping suit engaging gear (4) and the off-centre bearing up pulley (5) of stopping.Swing arm change gear (10) is the splined hole wheel, be fixedly set on the pivot shaft (2), clamping plate (11) upper end is fixed together with swing arm change gear (10), the lower end clips swing arm guide wheel (12) and is sleeved on the swing arm wheel shaft (13), and fastening with groove nut (14), pass in the clamping plate (11) of derrick line (16) between swing arm change gear (10) and swing arm wheel shaft (13).Two engaging gears (4) are in engagement all the time, when derrick line (16) tension, make swing arm partly rotate 45 and be strained condition, driving engaging gear (4) by pivot shaft (2) rotates, extension spring (7) tension, simultaneously the off-centre bearing up pulley (5) of stopping rotates intermediate gaps is increased, unclamp safety rope (9), when derrick line (16) fracture of tension or derrick line (16) when being in relaxation state, swing arm partly is in the nature upright position, and extension spring (7) drives pivot shaft (2) with engaging gear (4) pulling revolution, gear wheel shaft (3) rotates, make the off-centre bearing up pulley (5) of stopping recover initial position, the gap dwindles, and jam-packed safety rope (9) is fixed hanging basket, play the voluntary insurance effect, guarantee safety.In order to guarantee balance, support section, insurance part, swing arm part respectively are two covers, are installed in respectively on the building hanging basket both sides steel pipe frames (17).Safety rope (9) is gone up the termination suspension hook and is hung on the cantilever (15) that stretches out on the building, and stop space between the bearing up pulley (5) of two off-centre is passed in the centre, and the lower end twists on the insurance rope sheave (18), the rolling-in or loosen with the lifting of building hanging basket.Under the derrick line normal circumstances, safety rope (9) is in relaxation state, and derrick line when fracture, safety rope (9) is clamped and pins by the off-centre bearing up pulley (5) of stopping, and stable hanging basket plays the voluntary insurance effect.
Through above-mentioned design, trial-production, test, prove that the utility model meets the supporting requirement of building hanging basket, safe and reliable, simple in structure, to be convenient to install, reaction is flexibly, can play safety effect automatically, adapt to all kinds of building hanging basket needs of work, realize giving the meter target preferably.
