Abstract

The invention discloses an electric and manual windlass movable pulley conveying device belonging to the class of conveying machineries. The conveying device comprises four parts including a vertical trapezoid supporting structure, a windlass and movable pulley labor-saving structure, a power-driven structure and a manual control mechanism and can easily and conveniently finish the conveying task under the states of energization and deenergization. The invention is mainly applied to the conveyance of goods and materials or people in one-storeyed bungalows, two-storeyed buildings or three-storeyed buildings in countryside or some cities to fill in the gap that a labor-saving and convenient conveying tool is not provided for low storeyed buildings in vast countryside or some cities in China.

Description

Electric and manual windlass movable pulley conveying device

Technical field:

The present invention relates to a kind of feedway, belong to industrial conveying machinery class.

Background technology:

Now, the low-rise building in vast rural area of China or part city, individual layer or two layers, three layers flat-top reinforced concrete structure of adopting more, this building is not only firm generous, and its smooth end face is commonly used to shine grain or deposit other goods and materials, therefore carry just become very general to the goods and materials of rancher top or two layers three layers, but these low-rise buildings do not have elevator more, have only narrow stair, how the conveying of goods and materials is by artificial, to lighter object with a dead lift still can, and heavier Articles transfer is just quite wasted time and energy.Especially the present situation in China rural area, strong male labour power often go out to do manual work, and family's rear personnel's majority is weak women, old man or children of power monomer, and will finish the conveying to hoisting than heavy object, are not an a piece of cake really.

The objective of the invention is to design a kind of simple structure, with low cost, rely on little to electric power, floor area is few, simple again, laborsaving, low-rise building means of delivery easily, in the labour intensity, also can save the limited space of courtyard or floor alleviating people greatly in course of conveying, reaching is the easy and convenient again result of use of economy.

Summary of the invention:

For laborsaving, finish goods and materials or personnel's conveying task easily, upright terraced supporting mechanism, winch and movable pulley effort-saving mechanism, four parts of power-driven mechanism and manual control mechanism have been adopted in the design of this feedway.Upright terraced supporting mechanism is made up of upright ladder, support rail and spiral adjusting lever, in order to connect, member and load-bearing such as fixing and support winch, electrical motor, change speed gear box, power-transfer clutch.Winch and movable pulley mechanism are made up of winch, movable pulley and one-way brake ratchet, and it mainly acts on is to cooperatively interact with actuating unit to finish conveying, and during manual feed, reach light labour-saving purpose under no electric condition.Power-driven mechanism is made up of electrical motor, change speed gear box, power-transfer clutch, transmission shaft, transmission gear and bearing bearing etc., and its role is to provides power to device.Manual control mechanism is made up of winch, movable pulley and manual rocking handle, is mainly used in the M/C under the electroless state.Consider that device is many and place in the open and in conjunction with the basic condition in China rural area, this device has also designed protective cover and the burglary-resisting installation that locks, with the burn into damage that prevents apparatus or lose and stolen.

The specific embodiment:

At first; Build a pedestal at building wall 38 outsides (the about 0.8 meter) correct position that need are carried with the sandstone concrete; To found ladder 26 (solid 26 and the vertical terraced cross bar 15 on it mainly make things convenient for about the personnel) bottom support bracket 27 builds in pedestal; Keep vertical ladder 26 vertically vertically with laterally parallel with metope as far as possible; And make base top surface 31 (be convenient to draining a little more than ground; Prevent corrosion); Then will be with hoist cable 34; Ratchet 10; Winch rotating shaft 5; Gear wheel 4; The winch 8 of rocking handle connecting hole 2 is loaded on the left support cross bar 14; The first inserting end of winch 8 is clamped on the axle left end one-way stop bearing 3b; After will be placed in respectively (pullover of right support cross bar 16 and right pole are fixed with bolt) on winch rotating shaft 5 and the right support cross bar 16 with bearing 3a and in two poles 32 that little cross bar 33 links into an integrated entity; Rotation is adjusted spiral adjustment 35 and is made a left side; Right support cross bar two ends slightly become level; After the bottom is fixed on (screw gets out with percussion drill) on the roof with expansion bolt 36; Again with motor 19; Power transmission shaft 20; Gearbox 21; Clutch 22; Pinion 23; Bearing 24; Motor switch 25 is connected and fixed on respectively the correct position that should assemble on middle studdle 13 and the right support cross bar 16; After hoist cable 34 is passed movable pulley 29 with suspension hook 30; The free end of hoist cable is hung on the load-bearing hanging nose of right support cross bar bottom, and assembling namely comes to an end.

When weight need be carried, at first, push the ratchet 9 that is compressed by ratchet dialing spring 18 aside with ratchet driving lever 44, push away ratchet stop bar 7 to stopping the ratchet state, open power-transfer clutch to " from " state, the square plug of rocking handle 1 is inserted in the square jack 2 of axle head, oppositely shake rocking handle 1, then the bottom hoist cable that carries movable pulley constantly descends, after reducing to correct position, tightly fasten weight and be hung on the suspension hook 30 of movable pulley bottom with the rope bolt, after retract ratchet stop bar 7, then ratchet 9 is under the elastic force effect of ratchet dialing spring 18, depend on the ratchet 10, take off rocking handle 1, power-transfer clutch closes, pressing motor switch 25 does not put, then motor power is through transmission shaft 20, change speed gear box 21, power-transfer clutch 22 drives miniature gears 23 and rotates, and miniature gears 23 drives big gear wheel 4, and big gear wheel 4 drives winch 8 and rotates, hoist cable 34 constantly is wound on the winch 8, at this moment, movable pulley drives weight and constantly rises, after weight rises to the roof, loosen motor switch 25, winch 8 automatic brake under the effect of ratchet 10 and ratchet 9 then, weight hover be in stop position, pulling stay cord 11, pull out expansion bracket 42 to the longest end after the retractable supports frame being pulled to the position that is higher than eaves 37, then elastic chuck 43 only blocks automatically, and the other end is then horizontal to be stayed on the plane, eaves top, takes off fishhook, weight is transferred to correct position, once carries and promptly come to an end.

In the time will carrying object downwards, jog rocking handle 1 is stirred ratchet driving lever 44 and is made it plate and open ratchet 9, push ratchet stop bar 7, control ratchet 9 in non-braking mode, plate clutch " from " the position, the pulling stay cord, adjust retractable supports frame 42, the weight that will carry is put on the retractable supports frame, hangs up suspension hook 30, shake rocking handle 1, withdraw gently and put down retractable supports frame 30, continue to shake rocking handle, till weight falls within ground.

When not having electricity, then plate declutch to " from " the position, only with winch and the conveying of movable pulley structure; Among the design, movable pulley can be economized 1/2nd power, and winch can be saved 3/4ths power, carries free and relaxed to the weight below 50 kilograms.

When the personnel of conveying, can under fishhook, hang corresponding safe basketry to finish conveying to personnel.

When installing the not time spent, then protective cover link 39 is hung on the protective cover hangers 17, cover protective cover 40, hanging nose hole 41 is hung on the hanging nose 12, lock lockset, to prevent the apparatus corrosion damage or to lose stolen.
