Fig. 2 is an enlarged view of the safety fixing device of fig. 1.

Wherein: the device comprises a suspension arm 1, a clamping hook connecting arm 2, a clamping hook 3, a fixing bolt 4, a fixing rod 5, an I-shaped wheel 6, a safety fixing device 7, a movable block 7.1, an upper half hole 7.2, a lower half hole 7.3 and a poke rod 7.4.

Detailed Description

As shown in fig. 1 and 2, the utility model relates to a spool hanger, including a davit 1, two clamp hook linking arms 2 and two clamp hooks 3, davit 1 top links to each other with the driving, and the bottom of davit 1 passes the upper end of two clamp hook linking arms 2 through a fixing bolt 4 for the upper end of two clamp hook linking arms 2 is articulated with davit 1, the lower extreme of two clamp hook linking arms 2 is articulated with the top of two clamp hooks 3 respectively, has worn a dead lever 5 in the middle of two clamp hooks 3, all articulates on dead lever 5 in the middle of two clamp hooks 3, makes two clamp hooks 3 be the X-shaped alternately, and the lower extreme of clamp hook 3 is the clamping part, can hold spool 6 after two clamp hooks 3 inwards rotate, and the diameter that opens of clamp hook 3 is slightly greater than the distance between the two dish limits of spool 6, in order to clamp spool 6.

Thus, when the suspension arm 1 is lifted or put down, the clamp hook connecting arm 2 and the clamp hook 3 can complete scissor-type lifting.

The lower extreme of davit 1 still is equipped with a insurance fixing device 7, and this insurance fixing device 7 passes through fixing bolt 4 and 1 is articulated with davit to fixing bolt 4 is eccentric design, and insurance fixing device 7 is the movable block of a rectangular shape, and the upper end of this movable block uses fixing bolt 4 as the strong point, and the movable block can eccentrically rotate like this, upper portion half bore 7.2 has been seted up to the centre of the movable block of rectangular shape, and the movable block is close to lower extreme department and has seted up lower part half bore 7.3, upper portion half bore 7.2 and lower part half bore 7.3 are the arc notch, and upper portion half bore 7.2 and lower part half bore 7.3 block are on dead lever 5 to let insurance fixing device 7 and dead lever 5 lock, still be fixed with a movable rod shifting 7.4 on the movable block and can operate the movable block and rotate.

The positions of an upper half hole 7.2 and a lower half hole 7.3 formed in the safety fixing device 7 are measured, and when the spool lifting appliance is completely laid flat, the upper half hole 7.2 can enable the fixing rod 5 to be clamped therein; when the I-shaped wheel lifting appliance is lifted, the lower half hole 7.3 can allow the fixing rod 5 to be clamped therein.

The I-shaped wheel lifting appliance is in a flat state before the upper disc, the opening angle of the clamping hook 3 is the largest, at the moment, the safety fixing device 7 on the suspension arm 1 falls down due to the action of eccentricity and gravity, the fixing rod 5 is locked in the upper half hole 7.2 of the safety fixing device 7, and the opening diameter of the clamping hook 3 is slightly larger than the distance between two disc edges of the I-shaped wheel 6, so that the I-shaped wheel 6 can be clamped conveniently; when the clamping hook 3 clamps the spool 6, an operator pulls the poke rod 7.4 upwards to enable the fixed rod 5 to exit from the upper half-hole 7.2, then the crane is started to pull the suspension arm 1 upwards, and the clamping hook 3 can clamp the spool 6 inwards after receiving the upward pulling force; at this moment, the operator puts down the safety fixing device 7 again, the safety fixing device 7 falls under the eccentric action and the gravity action, after the clamping hook 3 is clamped tightly, the distance between the suspension arm 1 and the fixing rod 5 is lengthened, the safety fixing device 7 enables the fixing rod 5 to enter the lower half hole 7.3, the arc-shaped notch can prevent the fixing rod 5 from automatically falling off from the half hole, and the safety fixing device 7 cannot be disengaged even if the spool 6 touches an object or is placed on a wire frame, so that the safety function is effectively realized, the operation of the upper disc and the lower disc of the spool is simple and convenient, and the use process is safe.
