Detailed Description
In order to make the technical purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention are further described below with reference to fig. 1 to 7 and specific embodiments.
An embodiment of a turning sling for metro tapping:
the utility model provides a subway is upset hoist for slagging tap, including two straight-bars 1 that set up side by side, the bottom of straight-bar 1 is provided with the upset hook 2 that is used for catching the hopper, still include push-and-pull mechanism and many spliced poles 3 of horizontal fixed connection between two straight-bars 1, push-and-pull mechanism includes electric liquid push rod 4, wire rope 5 and leading wheel 6, electric liquid push rod 4 installs on dolly frame 7 through first mount pad 8, concretely, first mount pad 8 detachably fixes on dolly frame 7, the box of electric liquid push rod 4 is fixed on first mount pad 8, leading wheel 6 installs on dolly frame 7 through second mount pad 9, with the position of hopper hoist 10 for two straight-bars 1 forward, the top of straight-bar 1 articulates on dolly frame 7, electric liquid push rod 4 is located the top front side of straight-bar 1, leading wheel 6 is located the top rear side of straight-bar 1, wire rope 5's one end is connected with the piston rod end of electric liquid push rod 4, the other end of the steel wire rope 5 is connected with the middle part of one connecting column 3.
When the straight rod 1 of the turnover lifting appliance vertically hangs down, the piston rod of the electro-hydraulic push rod 4 is in a stretching state, when the hopper needs to be tipped, the piston rod of the electro-hydraulic push rod 4 retracts, the straight rod 1 is driven to rotate around the hinged position of the top end and the trolley frame 7 through the steel wire rope 5, and therefore the hopper is hooked through the turnover hook 2 to tip. When the steel wire rope 5 drives the straight rods 1, the two straight rods 1 can synchronously act through being connected with the connecting column 3 between the two straight rods 1, so that the tipping action is stably finished.
The guide wheels 6 and the steel wire ropes 5 can change the direction of force, and the horizontal movement of the electro-hydraulic push rod 4 is applied to the turning movement of the straight rod 1, so that the device is more reliable than a connecting rod mechanism.
Further, as shown in fig. 2 to 4, the other end of the steel wire rope 5 is connected with the connecting column 3 through a fixing piece, the fixing piece includes two fixing plates 11 which are arranged oppositely, one end of each fixing plate 11 is fixed on the connecting column 3, a fixing shaft 12 penetrates between the free ends of the fixing plates 11, a lantern ring 13 is installed on the fixing shaft 12, and one end of the steel wire rope 5 is fixed through a rope clamp 14 after bypassing the lantern ring 13. The lantern ring 13 is arranged to reduce abrasion of the steel wire rope 5 and prolong the service life of the turnover lifting appliance.
Further, a rope groove is formed in the collar 13 along the circumferential direction. The steel wire rope 5 bypasses the lantern ring 13 through the rope groove, so that the steel wire rope 5 can be prevented from moving, and the stability is improved.
Further, second mount pad 9 includes two guide pulley mounting panels 15 that set up relatively, wears to be equipped with pulley shaft 16 between the guide pulley mounting panel 15, and pulley shaft 16's both ends fixed connection is on guide pulley mounting panel 15, and leading wheel 6 rotates to be connected on pulley shaft 16.
