Abstract

The utility model discloses a new hoister for hoisting in construction industry, being composed of a bracket, an end cover, a winding drum, a fixed frame, a motor, an input end cover, a pin shaft component, a planetary gear, an inner gear, an arm shaft, a bottom frame, an eccentric wheel, a bobbin shaft, etc. The motor which is fixed in the rope drum is connected with a speed reducer, and accordingly, the volume of the hoister can be reduced. A plurality of pin shaft fixing holes are arranged on the input end cover, an oil sealing groove is arranged on one end surface, so that the utility model has the advantages of simple structure, small volume and light weight.

Description

Hoister

The utility model is that a kind of building industry that is used for works the novel winch of reusing.

Relevant by retrieval document does not retrieve the winch identical with the utility model structure at present as yet.The winch keystone configuration that is used in existing the production by the driven by motor retarder, drives rope roll work for motor, retarder and rope roll part to be installed again on underframe.Owing to be subjected to the restriction of retarder, motor oad, so existing winch all seems huge and heavy, particularly in outside work and resettlement, seem inconvenient especially, and because volume is big, Heavy Weight is so the price of product also is expensive.

The purpose of this utility model is that a kind of compact conformation, reasonable, the closed novel winch of failure-free will be provided.

Technical characterictic of the present utility model is: utilization involute less tooth difference gear reducer principle of work is designed to assemble the winch that constitutes by support, end cap, rope roll, fixed mount, motor, input end cap, bearing pin parts, planetary wheel, inner gear, arm axle, underframe, bearing I, bearing II, eccentric wheel, key, bearing III, passing spool, and it is characterized in that: the two ends at rope roll are fixed with end cap; On the inwall of rope roll, be fixed with inner gear; On end cap, be provided with the bearing III; Passing spool one end is packed on the support, and the other end is packed on the fixed mount; On fixed mount, be fixed with motor; On motor, be fixed with the input end cap; Cover at input end and to be fixed with several bearing pin parts; The bearing pin parts pass planetary wheel and are packed on the arm axle; On the output shaft of motor, be provided with eccentric wheel, key; On eccentric wheel, be provided with planetary wheel; Planetary wheel and inner gear engagement; On arm axle, be provided with the bearing I.

When the needs hoisting heavy, connect motor power, motor is started working and is driven the eccentric wheel rotation by motor output shaft, and forces planetary wheel and inner gear engagement by the bearing II.Because motor is fixed on the support by fixed mount, passing spool, the input end cap is packed on the motor, so the bearing pin parts remain static, and contacts with pin-and-hole wall on the planetary wheel all the time, and make planetary wheel and inner gear engagement, drive the rope roll rotation work thereby promote inner gear.The rotating speed of rope roll is determined by the inner gear and the planetary number of teeth.Motor adopts existing motor to form through the transformation of the way.The input end cap is packed on the support of motor, can play electric motor end cap and install the effect of bearing pin parts.Power lead passes through from passing spool, and passes fixed mount and receive on the motor.

The utility model has the advantages that: because motor is packed in rope roll inside, thereby and greatly compact with the link structure that makes winch of deceleration part; Owing to be provided with passing spool, arm axle, thereby reduced the torsion of rope roll; Be provided with several bearing pin fixed orifices owing to covering at input end, end face is provided with the oil sealing groove, thereby simplifies the structure, and has improved accuracy of positioning; Because little, in light weight, the good looking appearance of volume is so have bigger application and promotional value.

Below with reference to description of drawings embodiment of the present utility model.

Accompanying drawing 1 is the structural representation of the utility model winch

Accompanying drawing 2 is structural representations of winch input end cap

With reference to accompanying drawing 1, upward be fixed with end cap (2) with bolt at rope roll (3); On the inwall of rope roll (3), be fixed with inner gear (9) with bolt; On end cap (2), be provided with bearing III (16); Passing spool (17) is housed on the internal diameter of bearing III (16), and passing spool (17) one ends are packed on the support (1) with key, and the other end is packed in fixed mount (4) with key; Motor (5) is packed on the fixed mount (4) with screw; Input end cap (6) is packed on the support of motor (5) with screw; On the output shaft of motor (5), be provided with eccentric wheel (14), key (15); On eccentric wheel (14), be provided with two bearing II (13); Planetary wheel (8) is housed on bearing II (13); Bearing pin parts (7) one ends are packed on the input end cap (6), and the pin-and-hole wall that an end passes planetary wheel (8) is packed on the arm axle (10); The bearing I (12) that is provided with on arm axle (10) is the output shaft that is used for supporting motor (5); Arm axle (10) is packed on the support (1) by key; The external diameter of arm axle (10) is provided with bearing III (16) thereby has supported rope roll.Support (1) is packed on the underframe (11) with bolt.

With reference to accompanying drawing 2, on input end cap (6), be provided with several bearing pin fixed orifice A, end face is provided with oil seal groove.
