Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0016] The present invention is a free-falling hoist brake device applied to a dynamic compaction machine, comprising: a free-falling dynamic compaction machine hoist 2, a brake 7; the inner brake pad 17, the outer brake pad 16, and the bearing I3 of the brake 7 Bearing Ⅱ12, circlip Ⅰ4, and circlip Ⅱ14 are arranged on both sides. This arrangement can increase the braking torque by two times. Compared with the one-sided arrangement, the diameter of the same braking torque is greatly reduced. A series of problems caused by the excessively large diameter of the brake pad; the transmission shaft 1 is radially supported by the bearing Ⅰ3 and the bearing Ⅱ12, and the elastic retaining ring Ⅰ4 is stuck in the groove of the supporting seat 5; the spline sleeve 18 is connected with the inner spline Drive shaft 1 is connected; circlip Ⅱ14 is stuck in the slot of drive shaft 1,...

Abstract

The invention discloses a free falling body winch brake device applied to a dynamic compactor. The free falling body winch brake device comprises a free falling body dynamic compactor winch and a brake, wherein inner brake sheets, outer brake sheets, a bearing I, a bearing II, an elastic check ring I, an elastic check ring II of the brake are in bilateral arrangement; a transmission shaft is radially supported by the bearing I and the bearing II, and the elastic check ring I is clamped in a clamping groove of a support base; a spline housing is connected to the transmission shaft through an inner spline; the elastic check ring II is clamped in the clamping groove of the transmission shaft; the inner brake sheets are connected to the spline housing through the inner spline; the outer brake sheets are connected to the outer ring of the brake through an outer spline; a piston is mounted in the inner cavity of the outer ring of the brake; a big spring is mounted in a piston hole, a middle spring is mounted in the inner hole of the big spring, and a small spring is mounted in the inner hole of the middle spring; the outer ring of the brake is connected to the support base through a bolt I. The free falling body winch brake device applied to the dynamic compactor solves a series of problems caused by oversize diameter of the brake sheets; as three groups of combined springs are adopted by the brake, the whole structure is more compact.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a brake device of a free-falling hoist applied to a dynamic compaction machine. Background technique [0002] At present, the hoist for the free fall dynamic compaction machine has not been successfully studied in China. Foreign companies produce the winch for the free fall dynamic compaction machine. However, the brake part of the winch for the free fall dynamic compaction machine is arranged on one side, which makes the brake disc diameter Very large, which brings a series of problems: [0003] (1) At a high speed of nearly ten thousand revolutions per minute, the larger the diameter of the brake pad, the greater the linear speed and the greater the wear of the brake pad. [0004] (2) The larger the diameter of the brake pad, the greater the centrifugal force generated by the high-speed rotation of the brake pad, the higher the required material properties, the increase of the mome...
