Embodiment 1

[0026] Such as Figure 1-2 The shown non-powered grab bucket of the present invention includes two bucket bodies 5, and a shaft joint 3 is arranged above the two bucket bodies 5. The shaft joint 3 is sleeved on the beam bar 1, and the lower part of the beam bar 1 is provided with a trapezoidal groove. 20. The beam 21 at the bottom of the beam bar 1 is fixed to the inside of the opening of the bucket body 5 through the bucket body pin 19, and the hub 6 is set on the beam bar 1 between the shaft joint 3 and the beam 21, and the side of the hub 6 is provided with an adjustment wheel 16. A guide wheel 17 is provided on the side of the shaft joint 3, and the adjustment wheel 16 and the guide wheel 17 are on the same side. Block 18 fixes one end of the steel wire rope 2, the other end of the steel wire rope 2 bypasses the adjustment wheel 16, passes through the guide wheel 17, and fixes it with the earring 9 on the top of the beam bar 1, and the bottom of both sides of the shaft joi...

Embodiment 2

[0028] One end of the steel wire rope 2 is directly fixed on the shaft joint 3, and the others are the same as in Embodiment 1.

[0029] Working principle of the present invention:

[0030] The grab is closed, the grabbing process: if Figures 3a-3c As shown, first the grab is in an open state, the hub pin 7 is inserted into the trapezoidal groove 20 at the bottom of the beam bar 1 through the hub 6, the crane hook hangs the earring 9, and when the crane moves the grab to the top of the pile, The hook pulls the wire rope 2 upwards, tightens the wire rope 2 and adjusts the wheel to drive the wheel hub 6, and the hub 6 drives the beam rod 1 to move upwards, forcing the shaft joint 3 to close the bucket body 5 through the action of the connecting rod 4 to realize the grabbing process. Now No. 1 spring 8 is in stretched state.

[0031] Grab open, unloading process: such as Figure 3d-3f As shown, the crane hook is hung on the earring 9, and now the trapezoidal boss 23 at the fr...

Abstract

The invention discloses a grab bucket, in particular to a power-free grab bucket. A transverse beam rod is arranged above two bucket bodies; the lower part of the transverse beam rod is provided with a trapezoidal groove; a wheel hub is sleeved on the transverse beam rod between a shaft joint and a transverse beam; the side face of the wheel hub is provided with an adjusting wheel; the side face of the shaft joint is provided with a guide wheel; one end of a steel wire rope is fixed on the shaft joint, and the other end of the steel wire rope is fixed with a lug ring; the shaft joint is fixedwith connecting rods; two connecting rods are connected with a curved bar through curved bar pins; one side of the wheel hub is provided with a wheel hub pin; a lock catch lining with trapezoidal screw threads is sleeved on the wheel hub pin; the outer side of the lock catch lining is provided with a nut with annular trapezoidal screw threads; the front end of the wheel hub pin is provided with atrapezoidal boss; the trapezoidal boss is provided with a No.2 spring; the annular trapezoidal screw threads are connected with No.1 spring; and the No.1 spring is connecting with the curved bar pins. The power-free grab bucket has a simple structure, working reliability and low cost. Materials can be conveniently transferred without any pneumatic or hydraulic device.

Description

technical field [0001] The invention relates to a grab bucket, in particular to a non-powered grab bucket which is used for transferring powdery materials on site and uses self-weight and springs to realize non-powered loading and unloading. Background technique [0002] As a common equipment for transferring materials, the grab bucket has a high utilization rate on site. The power source of the commonly used grab bucket is pneumatic and hydraulic drive. It must be equipped with corresponding pneumatic and hydraulic devices, resulting in higher equipment costs, complicated maintenance, and high maintenance costs. Therefore need to develop a kind of simple in structure, reliable in operation, the grab bucket device with low cost. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a non-powered grab bucket, the purpose of which is to simplify the grab bucket structure, make it work reliably, reduce th...
