Problems solved by technology

[0004] Most of the breaking hammers currently used in the market are hydraulic breaking hammers. Due to the complex structure of hydraulic breaking hammers, high use and maintenance costs, small single impact energy, and low crushing efficiency for large ore and hard materials, resulting in related industries. Difficult to improve production efficiency

Embodiment 1

[0038] This embodiment provides a falling weight hydraulic breaker, which includes a hammering device and a hydraulic system, and the hammering device is connected to the hydraulic system. Among them, such as figure 1 and figure 2 As shown, the hammering device includes a guide cylinder 1, a lifting mechanism, and a weight 4. The weight 4 is set in the guide cylinder 1, and the weight 4 is connected to the lifting mechanism. The lifting mechanism drives the weight 4 to move axially along the guide cylinder 1. , to achieve the hammering action.

[0039] Specifically, the guide cylinder 1 is a hollow cylinder or a square cylinder formed by welding section steel. A linear guide rail extending from the bottom to the top is provided inside the guide cylinder 1 along the axial direction, and the weight 4 is slidably connected to the linear guide rail. A first connecting piece 7 is installed on the side of the guide cylinder 1, and the first connecting piece 7 is used for connect...

Embodiment 2

[0058] This embodiment provides a crushing device, including construction machinery and the hydraulic breaker described in Embodiment 1. The hydraulic breaker is installed in front of the construction machinery through the first connecting piece 7 .

[0059] The heavy hammer 4 extracts the hydraulic oil in the oil tank of the construction machinery through the hydraulic oil pump installed on the construction machinery. The oil enters the hydraulic motor 2 through the proportional valve 13, drives the hydraulic motor 2 to rotate, and then drives the reel 3 to rotate. The pulley assembly lifts the weight 4, and the weight 4 accelerates up along the linear guide rail inside the guide cylinder 1.

[0060] When the weight 4 is lifted close to the top, the position of the weight 4 is detected by the travel switch, and the controller 14 sends a signal to the brake device, the brake device starts, stops the rotation of the reel 3, and the weight 4 stops at the predetermined position. ...

Abstract

The invention discloses a falling weight hydraulic breaker and its equipment. The technical solution is: comprising a hammering device and a hydraulic system. The hammering device includes a guide cylinder and a weight arranged inside the guide cylinder. The weight The lifting mechanism is connected, and the lifting mechanism is connected with the hydraulic system; under the action of the hydraulic system, the lifting mechanism can drive the weight to move axially along the guide cylinder. The invention has the advantages of simple structure, high production efficiency and stable working process.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a falling weight hydraulic breaker and equipment. Background technique [0002] Among commonly used crushing devices, hammer crushing devices are widely used, such as crushers, hydraulic hammers, etc. The hammering device is a device that converts the hydraulic energy input by the host into mechanical impact energy. It is usually mounted on loaders, excavators and other construction machinery to complete rock crushing, building demolition, etc., and is widely used in mining projects. and civil engineering. In the production process of the steel industry, large-scale waste and slag will be generated, and hammering devices are often used to complete tasks such as ladle deslagging and crushing slag. [0003] The hammering device is equipped with a very heavy hammer head, which mainly uses the great impact energy generated by the free fall of a large-mass hammer from a cer...
