Description
Technical field
Basis is applicable novel relates to a kind of lifting device, is the perpendicular tongs for the vertical handling of various metal plate member.
Background technology
The handling of the various board of common perpendicular tongs widespread use, in use, the Indentation Damage of the plate surface caused is the problem that can not be ignored.Existing perpendicular tongs principle of work is: during lifting, and utilize the tooth of the upper lower platen of perpendicular tongs to be extruded corresponding profile of tooth trace by hanging component, tooth is engaged mutually with impression, prevents from being come off by hanging piece.Such handling process, causes general steel plate impression at 0.2 ~ 0.5mm; Component or the board such as corrosion-resistant steel, copper alloy, aluminum alloy that lifting material is softer, depth of indentation, at 0.4 ~ 0.9mm, in fact changes by hanging piece local thickness, and then shortens its service life.
be suitable for novel content
This is suitable for novel object and is, design a kind of with safeguard function, can avoid causing the perpendicular tongs damaged by hanging piece surface indentation.
Technical scheme: this is suitable for novel perpendicular tongs structure and comprises: the tongs caliper of steel plate installed-welded is main steel frame, the lower platen of tongs caliper bayonet socket part composition, the upper holder block composition that can move in parallel, cam composition, lever composition, arm, protection cushion block, handle form, connecting rod.Upper holder block composition is by it can the circular shaft of movement in tongs caliper skewed slot be connected with tongs body; Cam composition to consist of with upper holder block connecting rod and is connected, and is connected with arm by round pin; Lever composition to consist of with handle circular shaft and is connected, and to consist of be connected round pin with cam.
The upper holder block composition of tongs, lower platen composition have been provided with protection and have increased the pressing plate backing plate of friction force effect, and pressing plate backing plate adopts rubber, polyurethane, nylon material and other soft abrasion-resistant material.
Arm pulls the rotation with rotating band moving cam composition, the rotation compressing upper holder block composition of cam composition moves downward, the circular shaft formed on it due to upper holder block is inserted in tongs caliper skewed slot, making it can only do along tongs caliper skewed slot, upper and lower oblique parallel moves, when upper holder block composition moves downward, the pressure that bearing pin on it is subject to tongs caliper skewed slot produces transverse force, drives upper holder block to form parallel clamping by lifting part; Otherwise arm, to pressing down and rotating backward, drives rotating backward of cam composition upwards to pull upper holder block to form upwards oblique movement, unclamps lifting part.
Handle composition rotates and drives lever composition to rotate, and realizes the function of the rotation direction controlling cam composition further, avoids accidentally colliding with in handling to make cam form unordered rotation, drives upper holder block composition disordered motion, may make by the problem of hanging piece accidental.
Tongs has been provided with the protection cushion block of buffer action below, and material is polyurethane, nylon.
Basis is applicable novel to have the following advantages compared with prior art: pressing plate backing plate, lower protection cushion block adopt above-mentioned soft abrasion-resistant material material, play and prevent from being lifted the surperficial effect of being pressed, scratching of plate (part), soft abrasion-resistant material material friction coefficient greatly also plays and increases and its friction force simultaneously, effectively prevents by the lifting part effect of coming off; The rotation of arm, cam composition drives upper holder block composition to hang and does upper and lower oblique movement along pincers caliper skewed slot, upper holder block is formed compress and unclamp by the action of hanging piece, upper holder block composition be parallel compression by lifting part, further avoid it and pressed, scratch.
Beneficial effect: the perpendicular tongs without Indentation Damage can the handling of the various metal plate member of widespread use, maintain the features such as light, flexible, reliable, effectively prevent owing to lifting the damage of board surface indentation, the regional area that cause in advance tired and damage problem, the sheet material parts theoretical life-span was conformed to actual life, ensure that its safety used, indirect benefit cannot be estimated.

Detailed description of the invention
In Fig. 1, Fig. 2, perpendicular tongs caliper (1) is the skeleton of whole mechanism; Top board (3), top board pad (2), circular shaft (4), upper holder block (5) form upper holder block composition, and top board (3), top board pad (2) are connected with upper holder block (5) by bolt; Round pin (7), cam (8) form cam composition; Connecting rod (6) connects above-mentioned two compositions; Arm (9) is main force-applying piece; Spring (10), lever (12), lever shaft (13) form lever composition; Handle axis (11) handle (14) forms handle composition; Lower platen (17) and lower platen pad (16) form lower platen composition, are connected with perpendicular tongs caliper (1) by bolt; Lower protection cushion block (15) plays lower protective action.
In Fig. 3, when implementing lifting plate, according to being lifted the thickness of plate, arm (9) rotates clockwise, and side presses down cam (8) afterbody, cam (8) is rotated and separates with upper holder block (5), pull connecting rod (6) simultaneously, drive upper holder block (5) under circular shaft (4), perpendicular tongs caliper (1) skewed slot control, do upper oblique movement along caliper skewed slot, make jaw open up into suitable dimension size.Snap in by after lifting part, during lifting, arm (9) is to opposite side rotating band moving cam (8), cam (8) is rotated and pushes upper holder block (5) downwards, when upper holder block (5) moves downward, the pressure that circular shaft (4) on it is subject to perpendicular tongs body (1) skewed slot produces transverse force, drive top board (3), top board pad (2) clamping is by lifting part, complete clamping process, along with lifting, the counter-force of the pulling force that arm (9) is subject to is transmitted to cam (8) always, upper holder block (5), top board (3), top board pad (2), also horizontal clamping pressure is changed into, what top board pad (2) was subject to made upper holder block (5) move down by the downward friction force of hanging piece changes into lateral pressure further, at the end of lifting, repeat said process, make jaw open up into suitable dimension size, unclamp by lifting part.
In Fig. 4, Fig. 5, clamp by after lifting part, manpower turning handle (14), drive Handle axis (11) to rotate, drive lever (12) to rotate, lever shaft (13) pulls spring (10), strains cam (8) further, controls its rotation direction.
In Fig. 6, display lower platen (17), lower platen pad (16) and protection cushion block (12), lower platen (17), lower platen pad (16) play and prevent from being weighed wounded by lifting part the effect occurring impression, and lower protection cushion block (15) plays the effect preventing suspender from may scratch the part below by hanging piece.
