Abstract
The utility model relates to a loop chain type hand hoist, which belongs to the design of HSHZ (100) hand hoist serial products. The utility model is characterized in that a braking device is in a brake-releasing state under the action of a special clutching device, so a hoisting chain can be moved easily, safely and quickly. In addition, the design of a hand holding rubber sleeve at the end of a hand handle is unique in shape, which conforms to the functions of a human body. The utility model is a novel manual hoisting machine with compact structure, light weight, convenient operation and high safety.
Description
The utility model relates to a kind of hand crane tool, i.e. HSHZ(100) design of loop chain type Lever Blocks series of products.
Generally, the loop chain type Lever Blocks, the parts such as arrangement of clutch during by upper and lower cargo hook gear, brake equipment, gear drive, chain hoist wheel, hoisting chain, handle apparatus and hoisting chain quick travel constitute.
Since the loop chain type Lever Blocks have volume little, from heavy and light, durable in use, easy to use, function, the roughly similar advantage of characteristics to chain block, particularly in the colligation that is used for transporting object, fixing and traction, better in-use performance is arranged, so it also is a kind of broad-spectrum hand crane tool.
The just present various loop chain type Lever Blocks of producing and using, ubiquity that structure is not compact, outward appearance is coarse, unhandy defective, particularly when pulling moving hoisting chain, make the arrangement of clutch design of hoisting chain quick travel, drawback such as safe reliability is poor, design is unreasonable.In addition, the design of holding hand gum cover shape of handle end is also conservative stiff, also owes comfortable, safety in the use.
The utility model is at above-mentioned deficiency and the loop chain type Lever Blocks of a kind of novelty of design-calculated.Its basic model is 0.8t, 1.6t, three kinds of specifications of 3.2t, and other has 6.3t and two kinds of specifications of 9t of derivation.Now be described in detail as follows in conjunction with Figure of description:
Accompanying drawing 1 is the design's a housing construction generalized section.Its principle of work is to compress into handwheel 8, and clickwise makes arrangement of clutch be in the engage position knob 2 that will commutate again to pull about 50 ° " rising " position for about 40 °, make commutation ratchet 3 and 9 engagements of commutation ratchet, pulling handle 1 again does, back and forth pull down, rotation by commutation ratchet 9, friction lining 10 and drg seat 11 are compressed, drive major axis 14 right-hand revolutions, the engaged transmission of major axis 14 and plate gear 12 and minor axis 13 and splined hole gear 15, spline transmission by splined hole gear 15, chain hoist wheel 16 is rotated, move thereby make with chain hoist wheel 16 ingear hoisting chains 17, weight promptly rises with following suspension hook; Otherwise the knob 2 that will commutate is pulled to " decline " position, pulls handle 1 and does upper and lowerly back and forth to pull, and transmission direction is opposite, and weight promptly descends with suspension hook down.
The characteristics of this Lever Blocks are: during with manual quick travel hoisting chain 17 under special " arrangement of clutch " effect, can between friction lining 10 and brake ratchet 18, remain one greater than 1 less than 1.3 millimeters endplay, make it brake equipment and be in the brake off state, thereby reach the purpose of light, safety, quick travel hoisting chain 17.
The effect of above-mentioned special " arrangement of clutch " is achieved in that as shown in Figure 1, the knob 2 that will commutate pull " in " position, commutation ratchet 3 is thrown off with commutation ratchet 9, then compress into again and anticlockwise direction rotation hand wheel 8 about 40 ° of degree, handwheel 8 is stirred the rotation of commutation ratchet 9 anticlockwise directions, turn round in pressure under the thrust of cluster spring 7, " tooth " engagement on handwheel 8 and the position-limited wheel 4, at this moment location under compression spring 6 effects of the axial location of position-limited wheel 4 in movable sleeve 5, " key " on the handwheel 8 is connected with commutation ratchet 9, thereby produces a gap between friction lining 10 and brake ratchet 18.At this moment spur hoisting chain 17, chain hoist wheel 16 rotates, by gear transmission, and handwheel 8 is rotated with commutation ratchet 9, hoisting chain 17 upper and lower just can be light moving freely.
Because the brake equipment of this Lever Blocks is to adopt the braking of friction disk type one-way ratchet, utilize the load automatic brake of weight itself, so can only be when no-load could the quick travel hoisting chain, and when load is arranged, the Lever Blocks automatic brake, hoisting chain can not move fast with hand, and user's safety obtains reliable guarantee.This just from design radical change existing loop chain type Lever Blocks with manual quick travel hoisting chain the time, adopt out-of-gear or throw off the brake ratchet ratchet and cause that operation is inconvenient, mechanism is bigger and dangerous failure-free situation.
In addition, as shown in Figure 2, this Hand Grip of Lever Blocks 1 end is loaded onto holds hand gum cover 20, its characteristics have alternate concavo-convex circular shape for one side, the arc of holding when holding object with people's finger matches, hold hand gum cover 20 and do not hold corner protector is arranged, the finger that can prevent to damage because of overexerting, the salient point that prevents that gum cover from coming off on handle has also been designed in gum cover inside.Thereby the bodily fuctions is better brought into play, and safer during operation, comfortable, outward appearance is also graceful.
Claims (2)
1, a kind of loop chain type Lever Blocks, it is characterized in that: during with manual quick travel hoisting chain 17, the knob 2 that will commutate pull " in " position, by handwheel 8, press parts such as turning round cluster spring 7, position-limited wheel 4, movable sleeve 5, compression spring 6 and commutation ratchet 9 to form under the effect of special " arrangement of clutch ", can between friction lining 10 and brake ratchet 18, remain one greater than 1 millimeter, endplay less than 1.3 millimeters, make it brake equipment and be in the brake off state, thus can quick travel hoisting chain 17.
2, loop chain type Lever Blocks as claimed in claim 1, it is characterized in that: the design that handle 1 end is held hand gum cover 20, wherein one side is for there being alternate concavo-convex arc, the arc of holding when holding object with people's finger matches, and has collide with corner protector and gum cover inside of anti-finger to prevent to hold the salient point that hand gum cover 20 comes off at the end of holding hand gum cover 20.
