Problems solved by technology

[0003] After the hanging basket hoist is used for a period of time, the wire rope of the twisted strands will be broken, loose, bent, broken, and entangled due to wear and tear. Therefore, when the steel wire rope passes through the rope-pressing wheel, its broken ends, corners and other rope ends are easy to get stuck between the two rope-pressing wheels, causing the rope to be stuck.

Embodiment 1

[0021] Such as figure 1 As shown, the two left and right rope pressing wheels 1 of the anti-jamming rope pressing mechanism of the hanging basket hoist according to the present invention are assembled between the front and rear two fixing plates 3, and there is a certain distance between the two pressing wheels 1 . The outer peripheral surface of the pressure rope wheel 1 is provided with a concave rope guide groove 2 . The front and rear fixed plates 3 are trapezoidal in shape, and an inverted trapezoidal block 4 is fixed on the top edge of the trapezoidal block. The thickness of the trapezoidal block 4 is the distance between the front and rear two fixed plates 3. The height is the distance between two pressure rope wheels 1. More preferably, a groove is also arranged on the top surface of the trapezoidal block 4, and the groove is connected with the rope guide grooves 2 on both sides to form a rope passage for the steel wire rope. The trapezoidal block 4 can be fixed betw...

Embodiment 2

[0024] Such as image 3 As shown, the structure of the anti-jamming rope pressing mechanism of the hanging basket hoist according to the present invention is basically the same as that of Embodiment 1, the difference is that the trapezoidal block 4 is replaced by the bearing 5 . Bearing 5 can also play the role of blocking steel rope 7 from entering the gap between two pressure rope wheels 1, and the outer ring rolling of bearing 5 can also reduce the friction force when steel rope 7 passes simultaneously, so that the rope passing is smoother.

Embodiment 3

[0026] Such as Figure 4 As shown, the structure of the anti-jamming rope pressing mechanism of the hanging basket hoist according to the present invention is basically the same as that of Embodiment 1, the difference is that the front and rear two fixing plates 3 are stamped and folded from a whole plate with a connecting section 6 in the center. It is made by bending and is an integral structure. The length of connecting section 6 is suitable with the distance between two pressure rope wheels 1 on this height. The structural processing of this embodiment is more convenient, and the actual blocking effect is also better, which effectively prevents the rope from being stuck.

Abstract

The invention discloses a rope snapping and pressing resistant mechanism of a hanging basket hoist. A left rope pressing wheel and a right rope pressing wheel are arranged between a front fixing plate and a rear fixing plate. Certain distance is left between the two rope pressing wheels, a concave rope guide groove is formed in the outer circumferences of the rope pressing wheels, and rope retaining structures are arranged on the top sides of the front and rear fixing plates. By means of the mechanism, retaining blocks are arranged between the two rope pressing wheels, and accordingly, the rope snapping failure caused by rolling of the steel wire rope into a gap between the two rope pressing wheels can be prevented, and the hanging basket hoist operation reliability is improved effectively. Due to a trapezoid block structure, a channel from big to small can be provided for a rope head, so that the steel wire rope can pass smoothly; by means of the bearing outer circle rolling, friction during the passing of the steel wire rope can be reduced, so that the rope can be passed smoothly; an integral fixing plate structure with a connection section is arranged, so that the machining and the assembly can be performed simply and conveniently, and the actual blocking effect is good.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to an anti-jamming rope pressing mechanism of a hanging basket hoist. Background technique [0002] The hanging baskets for high-altitude operations need to be lifted by using the hanging basket hoists on both sides. The hanging basket hoist usually includes a box body, an inner toothed disc, a rope pressing mechanism, a rope divider and an inlet and outlet rope tube. The rope mechanism is used to press the wire rope into the rope guide groove on the outer periphery of the inner toothed disc. Existing rope pressing mechanism, such as the structure disclosed in Chinese patent "201120158716.6 --- aerial work platform hoist", includes steel wire rope, working rope wheel, spring guide rod head, spring, fixed spring seat, spring guide rod, long pressing plate, Short pressure plate, pressure rope pulley, long pressure plate pin shaft and short pressure plate pin shaft; the steel wi...
