Description

[0025] The auxiliary hanger 2 is composed of two auxiliary hanger plates 21 and a limit frame 22. The two auxiliary hanger plates 21 are symmetrically arranged front to back.

The avoidance hole 222 is provided corresponding to the fastener 74 and the outer diameter of the avoidance hole 222 is adapted to the outer diameter of the cross section of the fastener 74; when the position angle of the fastener 74 corresponds to the avoidance hole 222, the fastener 74 extends from the avoidance hole 222 into the locking groove 221, and the position angle of the fastener 74 is dislocated with the avoidance hole 222 through the further rotation action of the fastener 74, so as to realize the locking connection between the fastener 74 and the limit frame 22.

[0027] The center of the bottom end of the latching member 74 is convex so that the latching member 74 can rotate after the bottom end abuts against the bottom end of the latching slot 221 .

[0028] The lifting member 72 is arranged in a cylindrical shape, and the lifting member 72 is sleeved in the fixed sleeve 71 and the lifting member 72 can slide longitudinally relative to the inner wall of the fixed sleeve 71; a rotating groove 721 is provided on the circumferential side wall of the lifting member 72; pin shaft holes 711 are symmetrically provided on the outer wall of the fixed sleeve 71, and the axial direction of the pin shaft hole 711 is consistent with the radial direction of the fixed sleeve 71, and a rotating pin shaft 75 is provided in the pin shaft hole 711. The outer end of the rotating pin shaft 75 is rotatably connected to the end cover 76 fixedly connected to the outer wall of the fixed sleeve 71, and the inner end of the rotating pin shaft 75 extends into the rotating groove 721 and can move along the rotating groove 721. During the movement of the rotating pin shaft 75 along the rotating groove 721, it can rotate around the axis of the pin shaft hole 711 to reduce the moving friction.

[0029] The rotary groove 721 is arranged around the circumference of the lifting member 72, and four upwardly inclined upper curved guide surfaces 7211 are evenly arranged at the top of the rotary groove 721 along the circumference of the lifting member 72. The top of each upper curved guide surface 7211 is set as an arc vertex 7212, and a first vertical guide surface 7213 is set between the arc vertex 7212 and the bottom end of the adjacent upper curved guide surface 7211; the bottom end of the rotary groove 721 is evenly arranged along the circumference of the lifting member 72 There are four sections of downwardly inclined lower curved guide surfaces 7214, the bottom end of each section of the lower curved guide surface 7214 is set as a limit bottom point 7215 and a second vertical guide surface 7216 is set between the limit bottom point 7215 and the top of the adjacent lower curved guide surface 7214; the limit bottom point 7215 and the arc vertex 7212 are staggered, the limit bottom point 7215 is set below the upper curved guide surface 7211, and the arc vertex 7212 is set above the lower curved guide surface 7214.

[0030] Before the hoist is installed, the opening and closing control mechanism and the limit frame are in a separated state. At this time, the slewing pin is at the arc vertex of the slewing groove, and the position angle of the clip corresponds to the avoidance hole (such as Figure 4 Then, the hoisting equipment drives the main hanger closer to the auxiliary hanger, and the fastener passes through the avoidance hole and extends into the positioning slot (as shown in Figure 5 As shown), when the center position of the bottom end of the clip abuts against the bottom end wall of the positioning groove, the lifting member moves upward relative to the fixed sleeve, and the rotary pin moves downward to abut against the lower curved guide surface and slides along the lower curved guide surface. Under the abutting and sliding action of the rotary pin, the lifting member rotates in the opposite direction. When the rotary pin slides to the limit bottom point, the lifting member and the clip rotate 90 degrees, realizing the position angle misalignment between the clip and the avoidance hole (as shown). Figure 6When the lifting device is lifted upward, the main hanger, the fixed sleeve and the swivel pin move upward and abut against the upper curved guide surface, driving the clip to rise and contact the top end of the positioning groove. Under the action of the friction between the top end of the clip and the top end surface of the positioning groove, the swivel pin will not slide along the upper curved guide surface, and the opening and closing control mechanism and the limit frame are in a locking state, so that the first hook and the second hook in the lifting device are in an open state, and the lifting device can be moved to the carbon block position for lifting operation; when the first hook and the second hook in the opened state are placed on both sides of the carbon block, the lifting device is moved downward a certain distance, so that the top end of the clip no longer contacts the top end of the positioning groove. After the friction between the two is lost, the swivel pin will continue to slide along the upper curved guide surface to the top of the arc At this point, the lifting member continues to rotate 90 degrees in the opposite direction, so that the position angle of the fastener corresponds to the avoidance hole again. At this time, when the lifting equipment rises again, the fastener disengages from the avoidance hole, and the main hanger and the auxiliary hanger are relatively far away, so that the first hook and the second hook in the sling are in a clamping state and the charcoal block is clamped, and the charcoal block can be lifted to the use area with the sling; then the above actions are repeated continuously to realize the loosening action of the sling on the charcoal block and the lifting operation of the next charcoal block; its structure is simple, and the 90-degree automatic rotation action of the fastener can be realized through the structural design between the slewing groove and the slewing pin shaft, thereby automatically realizing the engaging and disengaging state control between the opening and closing control mechanism and the limit frame, and the whole process does not require human participation, which further improves the use effect of the present invention.

[0031] The present invention uses a method in which, before the hoisting operation is performed, the hoisting equipment drives the main hanger to descend and approach the auxiliary hanger, so that the opening and closing control mechanism between the main hanger and the auxiliary hanger is in a locked state. At this time, the first hook member and the second hook member are in an open state (such as Figure 3 As shown); Next, the hoisting device drives the entire sling to rise and place it on the upper end of the carbon block to be hoisted, so that the first hook member and the second hook member in the opened state are respectively located at the two ends of the carbon block; Then, the opening and closing control mechanism between the main hanger and the auxiliary hanger is in the loose state, and the hoisting device drives the main hanger away from the auxiliary hanger. Under the action of the lever, the bifurcated structures of the first hook member and the second hook member are relatively close to each other and clamp the end walls of the carbon block (as shown Figure 1As shown), as the lifting equipment continues to rise, the sling and the charcoal block are lifted together to the use area, and finally, the lifting equipment drives the main hanger to descend again and approach the auxiliary hanger, so that the first hook and the second hook are in the open state again, and the charcoal block can be stably placed in the use area, and the lifting equipment can carry the sling to lift the next charcoal block again; the whole lifting process is simple and fast, and the automatic lifting operation of the charcoal block can be realized without the use of manual labor and electric telescopic rods for assistance, which avoids the occurrence of power supply line entanglement and interference with the sling during the lifting process, reduces the production cost of the sling without affecting the normal lifting operation of the sling, thereby effectively improving the use effect of the charcoal block sling.
