Abstract

The utility model relates to an engine driving device for a water conservancy hoist, comprising a machine frame, an internal-combustion engine and a gearbox. The utility model is characterized in that the upper part of the machine frame is provided with the internal-combustion engine; the shaft end of an output shaft of the internal-combustion engine is provided with a triangular grooved pulley which is connected with a triangular grooved pulley on the shaft end of an input shaft of the gearbox arranged in the machine frame through a belt; a triangular grooved pulley on an output shaft of the gearbox is connected with a triangular grooved pulley on a worm screw of the hoist through the belt. The utility model has the advantages that the engine driving device can drive the hoist without a power supply, the engine driving device can reduce basic investment, can save energy and can increase the utilization rate of mechanical equipment as compared with that electric drive is realized by erecting power supply circuits for a long distance.

Description

The motor-driven actuator that is used for hoist

The utility model relates to a kind of motor-driven actuator that is used for the water conservancy hoist.

Mostly the motor-driven operation that is used for the worm-type open-close machine of middle-size and small-size water-control project and farmland water conservancy works at present is to adopt the Electric Traction form.The precondition that realizes this driving style is that the power supply area must be arranged.For setting up the power source special circuit away from the remote districts of power supply and the mobile operation of mountain area realization hoist.Because circuit is long, capital investment is big, and the utilization ratio of circuit is low, so these areas without electricity still adopt manual operation at present, this manual mode of operation not only takes a lot of work, and effort.

The purpose of this utility model is to provide a kind of electric power that need not, and uses the motor-driven actuator that is used for hoist flexibly.

Technical solution of the present utility model is: it includes frame, internal-combustion engine, gearbox, it is characterized in that: upper rack is equipped with internal-combustion engine, the output shaft axle head of internal-combustion engine is equipped with the triangle sheave, by belt be contained in frame in the input shaft axle head of gearbox on the triangle sheave be connected, the triangle sheave on the output shaft of gear-box is connected with triangle sheave on the hoist worm screw by belt.

Advantage of the present utility model is that it does not need power supply just can motor-drivenly drag hoist, sets up power circuit and realizes that electricity drags by comparison with long distance, can reduce capital investment, and energy saving improves the machinery utilization ratio, has tangible economic benefit.

Below in conjunction with drawings and Examples structure of the present utility model and principle are described in further detail.

Fig. 1 is the utility model overall structure schematic representation;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the gearbox plan view;

Fig. 4 is the gearbox designs schematic diagram.

Referring to Fig. 1 and Fig. 4.Upper rack is equipped with internal-combustion engine 1, and the output shaft axle head of internal-combustion engine 1 is equipped with triangle sheave 21, by belt 2 be contained in frame in input shaft 9 axle heads of gearbox 4 on triangle sheave 3 be connected.Set gear 10 on the input shaft 9, gear 13 engagements on the gear 10 and the axle of passing a bridge, and the colligator gear 20 on gear 13 and the output shaft 14 meshes.Colligator gear 15 on gear 11 and the output shaft 14 directly meshes.Colligator gear 15 and 20 equal skies are enclosed within on the output shaft 14, and ring 19, friction plate 16, cylinder 17, round nut 18 are housed between two colligator gears.Encircling 19 endoporus is splined hole, and friction plate has two kinds, a kind ofly packs in the breach of colligator gear 15,20 for endoporus circular hole outer rim has projection; Another kind of endoporus is that splined hole connects with output shaft 14 splined section, and outer rim does not have projection, but axial displacement.Two kinds of friction plates overlap mutually and are enclosed within the spline position of output shaft 14.Cylinder 17 endoporus are splined hole, but connect axial slip with output shaft 14 splined section, and cylindrical is a screw thread, and round nut 18 is equipped with at two ends, adjust the gap and the pressure size of round nut 18 may command friction plates 16.Joystick makes zygote 21 produce displacements through declutch shift shaft 27, gear 26, tooth bar 25, shift fork 24 and makes rocking bar 22 swings, cardan shaft 23 is moved axially and that cylinder 17 is done is left and right mobile.When cylinder 17 is moved to the left, make left end friction plate group produce frictional force, power is through input shaft 9, by gear 10,13 to 20 engagements of colligator gear, make moment of torsion export triangle sheave 5 to and make forward rotation, the triangle sheave 7 that drives on the hoist worm screw rotates, and realizes that the screw rod of hoist 8 moves upward.When cylinder 17 moves right, make right-hand member friction plate group produce frictional force, power is through input shaft 9, by gear 11 and gear 15 engagements, make moment of torsion export triangle sheave 5 to and make backward rotation, the triangle sheave 7 that drives on the hoist worm screw rotates, and realizes that the screw rod of hoist 8 moves downward.Handle gate opening and the purpose of closing thereby reach.
