Description
Technical field
The present invention relates to a kind of hydraulic clamp, belong to engineering machinery field.
Background technology
The first step first wants fixed object before the lifting of heavy goods is frequently problem in engineering, starting parcel,
The method of current fixed object is mainly the lifting type such as fork truck, and its principle is lifted a little so that object was being lifted for two for selection
Cheng Zhongneng realizes this fixed form for fastening rope hook extension of driving common in the balance of itself, or such as factory, and object is restricted
Hooked with the hook in driving after son bundle is good or directly hook some hole on object with the hook in driving and again carry object
Get up.The mode of fixed object has a limitation of its own before both liftings, the lifting type of such as fork truck, and it make it that object is carried
Experience of the balance completely with truck driver is kept during rising, and the pallet fork ability of certain space fork truck must be arranged at object bottom
Into so as to hold up object, rope hook-hang type needs to do the preparation of long period before lifting objects, and to object itself
Have certain requirement, such as either with or without the hole that can be used for hooking, this allow for lifting objects become in difficult and inconvenience, engineering because
For the inconvenience of fixed object, the carrying of many weights is still based on manpower, as the rectangle stone and bag of roadbed are done in afforestation
Filling carrying of transport of cement etc. many is realized with manpower, which increases cargo cost and operating efficiency is poor, severe
Working environment and heavy physical demands, hamper relevant industries and efficiently quickly develop always.
The content of the invention
The invention provides a kind of hydraulic clamp, to solve what is run into engineering before lifting objects during fixed object
Difficulty, the axial force of hydraulic pressure is converted into the clamping force axially vertical with it by it by the design of associated mechanisms, and hydraulic pressure is because of its axle
It is widely used to powerful power output in engineering, but it is very poor with axially vertical stress-bearing capability and easily damage
The axial force of hydraulic pressure is converted into the clamping force axially vertical with it by the design of mechanism and is used for realizing by its oil cylinder, the present invention
To the fixation of object before weight lifting, one object of lifting is reduced to clamp and the two processes are lifted.
The technical scheme is that：A kind of hydraulic clamp, including clamp holder I 1, clamp holder II 2, round key I 3, round key II
4th, round key III 5, connecting rod 6, upper bed-plate 7, support 8, bolt 9, nut I 10, nut II 11, crane arm 12, hydraulic top 13, lower bottom base
14th, hole I 15, hole II 16, hole III 17, hole IV 18, hole V 19 and hole VI 20；
Through the hole II 16 in the middle of crane arm 12 and with nut I 10 and the upper end of hydraulic top 13 at the screw thread of the upper end of hydraulic top 13
Crane arm 12 is fixed on hydraulic top 13 by the thread connecting mode between screw thread, and bolt 9 passes through the hole of the base of hydraulic top 13
And the centre position of lower bottom base 14 hole III 17 and hydraulic top 13 is fixed with the thread connecting mode between nut I 10 and bolt 9
On lower bottom base 14, one end of support 8 be placed through the hole I 15 of the surrounding of lower bottom base 14 and with nut II 11 by the end of support 8 at
Screw thread one end of support 8 is fixed on lower bottom base 14, the hole I 15 that the other end of support 8 is placed through the surrounding of upper bed-plate 7 is used in combination
The other end of support 8 is fixed on upper bed-plate 7 by nut II 11 by the screw thread at the end of support 8, and one end of connecting rod 6 passes through round key
I 3 are connected with the hole IV 18 on crane arm 12, and the other end of connecting rod 6 passes through the hole V on round key II 4 and clamp holder I 1 or clamp holder II 2
At 19 connections, the hole VI 20 that clamp holder I 1 and clamp holder II 2 are connected on lower bottom base 14 with round key III 5 by hole VI 20 in the middle of it；
Wherein clamp holder I 1, clamp holder II 2 are respectively two, and connecting rod 6 is four, and two connecting rods 6 connect clamp holder I 1, two connection clips of connecting rod 6
Handle II 2.
The connecting rod 6 is hinge company with clamp holder I 1, connecting rod 6 and clamp holder II 2, connecting rod 6 and the connected mode of crane arm 12
Connect.
The connected mode of the clamp holder I 1 and lower bottom base 14, clamp holder II 2 and lower bottom base 14 is chain connection.
The present invention operation principle be：
When needing to clamp weight, hydraulic top 13 is in the liter long status of pressurization, due to upper end by hole II 16 and nut I 10 with
Crane arm 12 is fixed, and will be pushed up crane arm 12 during hydraulic top is 13 liters long, crane arm 12 is in the form of a hinged connection
It is connected with connecting rod 6, connecting rod 6 is connected with clamp holder II 2, clamp holder I 1 in the form of a hinged connection, and clamp holder II 2, clamp holder I 1 are in the form of a hinged connection
It is connected with lower bottom base 14, so will be with connecting rod 6 and clamp holder when crane arm 12 is rising upwards in the presence of hydraulic top 13
II 2, clamp holder I 1 rises and connecting rod 6, clamp holder II 2, clamp holder I 1 connecting rod 6 and crane arm 12, connecting rod 6 and folder in this process together
Handle I 1, connecting rod 6 are with clamp holder II 2, clamp holder I 1 with clamp holder II 2 relative to the center that their round keys are connected, and its relative angle is in dynamic
In state change, the clamping position of the end of I 1 clamp holder of clamp holder II 2 that such movement effects will make is close to each other so as to realizing pair
The clamping process of weight body.
When needing to discharge weight, hydraulic top 13 is in the state of the shortening of decompression, because upper end passes through hole II 16 and nut
I 10 fix with crane arm 12, will pull down crane arm 12 during hydraulic top 13 shortens, crane arm 12 is with hinge
Form is connected with connecting rod 6, and connecting rod 6 is connected with clamp holder II 2, clamp holder I 1 in the form of a hinged connection, and clamp holder II 2, clamp holder I 1 are with hinge
Form is connected with lower bottom base 14, so will be with the He of connecting rod 6 when crane arm 12 is declining downwards in the presence of hydraulic top 13
Clamp holder II 2, clamp holder I 1 decline and connecting rod 6, clamp holder II 2, clamp holder I 1 connecting rod 6 and crane arm 12, connecting rod 6 in this process together
With clamp holder I 1, connecting rod 6 and clamp holder II 2, clamp holder I 1 and clamp holder II 2 relative to the center that their round keys are connected, at its relative angle
In dynamic change, the clamping position for the end of I 1 clamp holder of clamp holder II 2 that such movement effects will make is away from each other so as to real
The release process of existing pair weight.
The beneficial effects of the invention are as follows：The axial power output for causing hydraulic top huge by the design of mechanism is converted into can
It is enough to clamp the cross force of weight, its pressurization and release of pressure by simple hydraulic top is realized to be clamped and released to weight, is carried
The high efficiency of transport weight, alleviates the burden of manual labor.This clamping device can be hung and be consolidated by its upper bed-plate
Fixed mode is used cooperatively with many lifting machines.
