Abstract

The utility model discloses a vertical automatic clamp without connecting power sources, comprising a T-shaped framework, a movable upper jaw, a support jaw, a fixed lower jaw, a suspension ring lever system, a balance weight and a rotary clutch. The clamp is lifted up by a crane hook and supported on articles by the support jaw; by properly lifting and dropping the crane hook and under the action of the suspension ring lever system, the rotary clutch can rotate 90 DEG in each lifting and dropping process; so the movable upper jaw expands or closes; consequently the action of holding or loosening articles is completed. The utility model can lift up articles which are placed vertically and inconvenient for people to close. The utility model has the advantages of simple structure, safe operation, low investment and reducible production equipment, which is in particular suitable for lifting up articles such as glowing aluminium ingots, large concrete units, etc.

Description

Automatic vertical clamp

The utility model relates to a kind of clamp vertical, that do not need to connect in addition propulsion source, particularly a kind of automatic clamp with rotary clutch control.

Existing clamp all is to be used for the article of clamping horizontal positioned, can't the vertical article of placing of clamping, and do not adopt rotary clutch.

The purpose of this utility model be to provide a kind of be used for the vertical article of placing of clamping and only accurate holding articles A, B two planes, the time spent need not inserted the novel clamp of electricity, source of the gas again.Article such as aluminium ingot that its suitable especially handling is red-hot and large-sized concrete preform.Use this clamp can improve operation safety, reduce labor intensity, simplify production facilities, reduce investment outlay.

The purpose of this utility model reaches by following measure: Yi You Shang shape framework, movable upper jaw, supporting jaw, fixing lower jaw, and the vertical clamp formed of the suspension ring lever system that interrelates with the moving jaw axle, counter weight device and rotary clutch, rely on the supporting jaw that clamp itself is supported, suitable then lifting suspension ring lever system gets final product clamping or loosens article.

The drawing of accompanying drawing is described as follows:

Fig. 1, be the front view of the utility model structure; Fig. 2 is the right elevation of the utility model structure.

Below in conjunction with accompanying drawing (1) structure of the present utility model, principle of work and working process are further described.

(1), clamp is suspended on the used crane hook, suitably the lifting suspension hook makes power-transfer clutch (31) be in suitable position with suspension ring (1).At this moment clamp upper jaw (11) is in open configuration, continues to make the hoisting crane operation just the clamp handling can be transported on the article to quilt.

(2), clamp is placed on the article and supports by supporting jaw (7).Suspension hook is descended, and suspension rod (5) to lower slider, promotes upper jaw (11) by pull bar (10) in the guide groove of framework (6).Upper jaw (11) is (39) clickwise around the shaft.With the coaxial crank (40) of upper jaw (11) also clickwise, by link rod (29) power-transfer clutch is promoted to move down, collide until the tip, lower end (46) and the backing plate (22) that is fixed on the framework of power-transfer clutch.If continue suspension hook is descended then the height h of power-transfer clutch is compressed into h ₁↓, 45 ° of the shell of power-transfer clutch rotations simultaneously.

(3), suspension hook hoists at a slow speed, suspension rod (5) rises, by pull bar (10) pulling upper jaw (11) left-hand revolution.Because the effect of crank (40) and link rod (29), power-transfer clutch moves up, and the height of power-transfer clutch is by h ₁Return to h, clutch outer member is rotatable again 45 ° simultaneously.

Continue the suspension hook that hoists, upper jaw (11) continues left-hand revolution, until with article one plane contact.When the suspension hook a bit of distance that rises again, framework (6) also rises thereupon, and supporting jaw (7) no longer contacts with article, lower jaw (9) then with another surperficial contact of article.So far article are in the state of being held.Continue to start hoisting crane and the article that are held can be delivered to desired location.

(4), with the article handling after the required control position, article should be placed on the special stand.The crane hook that descends then, framework descend and are bearing on the surface of article by the supporting jaw.Continue the decline crane hook, then power-transfer clutch also and then descends, and after colliding with backing plate (22) when tip, power-transfer clutch lower end, after this 45 ° of power-transfer clutch rotations can make the crane hook rising, and power-transfer clutch continues to rotate 45 ° again.At this moment upper jaw (11) is in open configuration, and therefore starting hoisting crane just can be with the clamp handling to desired location.

(5), following principle of work to rotary clutch is further described:

When the tip, lower end of power-transfer clutch during by block, if link rod moves down, clutch dog (41) also moves down, and spring (42) is compressed.Clutch dog moves down in the process, the pin (44) on the shell (43) with slide along the lip-deep curved surface groove of clutch dog (41).Clutch dog (41) is connected by several bearing pins and framework, can not shell (43) be rotated around the Z-Z axle around the rotation of Z-Z axle.When the clutch dog dropping distance was stroke S, shell just in time rotated 45 °.After this, clutch dog rises, and spring opens, and pin (44) slides along the opposite side of the curved surface groove on clutch dog surface, and shell is rotated around the Z-Z axle.In brief, when clutch dog lifting one time, shell is half-twist just in time.Resistance when bearing (45) rotates in order to reduce shell is provided with.

The utility model compared with prior art has following advantage:

Easy to operate, safe and reliable, but the inconvenience of clamping lifting people near the article of (such as red-hot article), (comparing with tying up with steel wire rope); Equipment is simple, easy to manufacture, does not need electricity, source of the gas, and floor space is little, reduce investment outlay (with the manipulator ratio).

Claims

1, a kind of vertical automatic clamp, form by ┷ type framework (6), movable upper jaw (11), fixing lower jaw (9), supporting jaw (7) and with suspension ring lever system, counter weight device and rotary clutch (31) that moving jaw (11) axle interrelates for one, finish clamping and loosen the vertical automatic clamp of article by suitable lifting suspension ring lever system, it is characterized in that: clamp supports the jaw support by two, and finishes clamping handling article by a movable upper jaw (11) and two fixing lower jaws (9).The clamping of movable upper jaw with loosen be by lever system by rotary clutch under compression and situation about loosening, half-twist control.

2, by the rotary clutch of claim 1 defined, it is characterized in that: when the clutch dog pressurized, because tip, power-transfer clutch lower end is by block, spring is compressed.Pin on the clutch outer member (43) slides along clutch dog (41) curved surface groove, and makes power-transfer clutch (31) shell (43) produce rotation.When the distance that clutch dog (41) descends or rises equaled the stroke S of clutch dog (41), the shell of power-transfer clutch is the half-twist angle just in time.
