Abstract

The utility model relates to a hydraulic manipulator which consists of a manipulator and a hydraulic control box. The manipulator comprises a pedestal, a rotating body, a post arm, a front arm, a paw and a support oil cylinder. A hydraulic motor and a transmission mechanism are positioned inside the pedestal; the rotating body driven by a transmission mechanism is positioned on the top of the pedestal; the post arm articulated with the rotating body is supported and driven by a cylinder arranged between the rotating body and the transmission mechanism; the front arm articulated with the post arm is driven by the cylinder arranged between the transmission mechanism and the post arm; the paw articulated with the front arm is driven by the cylinder arranged between the transmission mechanism and the front arm; the support cylinder is fixed on the pedestal. The manipulator has the advantages of small volume, reasonable structure, being capable of meeting requirements for special working environment in mine because that firstly, the manipulator can be used as an auxiliary equipment of coal getting machinery to realize fast, effectively undercut and open gap at dead areas of coal mining, bringing coal mining machinery into full play; secondly, the manipulator can be used as mechanic appliance to recover the preset I-shaped steel sheds positioned at passageway of the working face end, recover single hydraulic pillar, clean passageway float coal and rock residue, etc.

Description

The multifunction hydraulic manipulator

Technical field

The utility model relates to mechanical device, is specially a kind of hydraulic efficiency manipulator.Be mainly used in excavation, the cleaning at the mechanical dead angle that the mechanical coal mining driving surface forms under the coal mine.

Background technology

Existing coalcutter coal cutting is behind the tail termination, cylinder does not cut dead angle area tunnel, transportation tail driving section ground coal, the gap that must manually undercut is transferred mobile tail, not only labor strength is big, and the speed of artificial gap far not satisfying coalcutter returns cutter coal mining requirement, can pin down the performance of mining mechanization advantage like this, output per man-hour will be subjected to very big influence.Therefore, the manually operated mill auxiliaries device that a kind of volume of needs is little, structure is simple relatively, be suitable for the underground work environment is used for the gap that undercuts to dead angle area.

Summary of the invention

The utility model is to adopt following technical scheme to realize: the multifunction hydraulic manipulator, be made of manipulator and the hydraulic control box two parts that comprise a plurality of fluid control valves, manipulator moves wheel by having, be provided with the base of HM Hydraulic Motor and transmission device in it, the swivel that base top is driven by transmission device, and swivel is hinged and by the postbrachium of the oil cylinder support drive between itself and swivel, and postbrachium is hinged and by the forearm of the hydraulic oil cylinder driving between itself and postbrachium, and the forearm end is hinged and be made of the paw of the hydraulic oil cylinder driving between itself and forearm and the support cylinder that is fixed on the base.This manipulator is a hydraulic-driven, and pressure medium picks up from the coal-cutting machinery hydraulic efficiency pressure system.Corresponding fluid control valve in the operating hydraulically operated control box, HM Hydraulic Motor can make by transmission device that manipulator moves forward and backward, the comprehensive rotation of swivel, manipulator is to control position, corresponding fluid control valve makes support cylinder withstand the top, tunnel in the operating hydraulically operated control box, thereby manipulator is located, handle corresponding fluid control valve again and control each oil cylinder, realize the action of manipulator.

Postbrachium of the present utility model can be oil cylinder, postbrachium can freely be stretched, thereby make manipulator that bigger action radius be arranged.

Multifunction hydraulic manipulator volume of the present utility model is little, rational in infrastructure, can satisfy the needs of particular job environment under the coal mine fully, can be used as the accessory device of coal-cutting machinery first, realize the coal-face dead angle area gap that undercuts fast and efficiently, thereby give full play to the advantage of coal-cutting machinery, alleviate labor strength, second can be used as a kind of manually operated machine tool be used for recovery operation face termination lame advanced supporting H shaped steel shack, reclaim hydraulic prop, cleaning tunnel float coal, rock quarrel etc., easy to use, laborsaving.

The specific embodiment

The multifunction hydraulic manipulator, constitute by manipulator and hydraulic control box two parts of comprising a plurality of fluid control valves, manipulator by have the base 3 that moves wheel 1, be provided with HM Hydraulic Motor 2 and transmission device in it, swivel 4 that base top is driven by transmission device, with swivel is hinged and by the postbrachium 6 of oil cylinder 5 support drive between itself and swivel, with postbrachium is hinged and by the forearm 8 of oil cylinder 7 drivings between itself and postbrachium, and the forearm end is hinged and be made of the paw 10 of oil cylinder 9 drivings between itself and forearm and the support cylinder 11 that is fixed on the base.

Transmission device in the base comprise by with the coaxial gear wheel shaft 15 of HM Hydraulic Motor, have driving mechanism that the retracing spring 18 on inside and outside tooth and internal tooth and gear wheel shaft gears in mesh 16, shift handle 17, the gear wheel shaft constitutes, the follower of the swivel follower that is made of gear 19, worm screw 20, worm gear 21 and the base wheel shaft that is made of

gear

22,23,24 constitutes.When shift handle is positioned at first retaining, the gear 16 of driving mechanism and 19 engagements of the gear of swivel follower, the comprehensive rotation of follower driven rotary body.When shift handle was positioned at second retaining, the gear 16 of driving mechanism was pushed forward gear 22 engagements with base wheel shaft follower, realizes the driving to the base wheel shaft, and when returning first retaining again, under the effect of retracing spring 18, gear 16 resets.

Hydraulic control box comprises the flow divider valve 25 and difference modulated pressure motor 2, support cylinder 11, postbrachium oil cylinder 5, postbrachium telescopic oil cylinder 6, forearm oil cylinder 7, fluid control valve A, the B of paw oil cylinder 9, C, D, E, F that is positioned on the pressure medium transfer conduit.

The pressure medium of coal-cutting machinery hydraulic efficiency pressure system enters manipulator by feed tube through hydraulic control box, and refluxes through counter flow pipe, forms the hydraulic pressure transmission system of manipulator.Operating hydraulically operated control cock A modulated pressure motor realizes that forward and backward the moving of manipulator reaches the swivel rotation; Operating hydraulically operated control cock B rises support cylinder and withstands the top, tunnel, prevents that manipulator from moving in the course of the work; Handle other each fluid control valve and control each corresponding oil cylinder, thus the action of realization manipulator.Used fluid control valve is known control block hydraulic unit with.
