Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of hoisting equipment, in particular to a mold insert vertical lifting device without lateral force. BACKGROUND
[0002] When hoisting the mold insert with the crane, the traditional way is to install the toothed lifting ring into the lifting tooth of the insert, and then hook the toothed lifting ring with two hook iron chains to lift the mold insert. This way, it is difficult to calibrate the hoisting angle of the crane, and the height of the two toothed lifting rings installed in the lifting tooth is often not the same. This way leads to a very large lateral force on the mold insert during hoisting, because the lateral force is large, which further increases the friction and stress deformation between the mold insert and the mold plate, making it more difficult to lift the mold insert, sometimes causing the entire mold to slide laterally, still unable to pull out the mold insert, and even causing damage to the mold insert or the mold. SUMMARY
[0003] The present application is to overcome the shortcomings of the prior art, and provides a mold insert vertical lifting device without lateral force.
[0004] To achieve the above purpose, a mold insert vertical lifting device without lateral force is designed, which comprises a pulley and a steel wire rope, characterized in that: the steel wire rope passes through the pulley, and a force balance adjusting mechanism is arranged below the pulley.
[0005] The steel wire rope is provided with a lifting hook at both ends.
[0006] The force balance adjusting mechanism further comprises a center ring, which is hung below the middle position of the pulley. A plumb line is arranged below the center ring, and the midpoint of a connecting piece one is fixedly connected to the lower end of the plumb line. A hanging buckle is connected to the steel wire rope, and a correction mark is hung on the center ring.
[0007] One end of the connecting piece one is fixedly connected to one end of a connecting piece two, and then the connecting piece two is connected to the hanging buckle through a connecting ring.
[0008] The connecting piece two and the plumb line are connected to the center ring through the connecting ring.
[0009] The connecting piece one is an elastic connecting piece.
[0010] The connecting piece two is a non-elastic connecting piece.
[0011] The correction mark is hung on both sides of the plumb line, and a ring one is arranged on one side of the correction mark. A ring two is sleeved on the center ring through the ring one.
[0012] The length of the correction mark is shorter than the length of the plumb line.
[0013] Compared with the prior art, the vertical rope and the correction mark can calibrate the lifting angle of the crane, and the influence of the lateral component force on the lifting part during lifting can be effectively reduced. BRIEF DESCRIPTION OF DRAWINGS

[0021] Referring to Figures 1-6 , wherein 1 is a pulley, 2 is a wire rope, 3 is a hook, 4 is a center ring, 5 is a correction mark, 5-1 is a circular ring one, 5-2 is a circular ring two, 6 is a vertical rope, 7 is a connecting piece one, 8 is a connecting piece two, 9 is a hanging buckle, 10 is a connecting circular ring, and 11 is a mold insert. EMBODIMENT
[0022] The present application will be further described below with reference to the accompanying drawings.
[0023] As Figures 1-6 shown, the wire rope 2 passes through the pulley 1, and a component force balance adjustment mechanism is arranged below the pulley 1, which comprises a vertical rope 6 and a naturally hanging correction mark 5.
[0024] The wire rope 2 is provided with a hook 3 at both ends.
[0025] The component force balance adjustment mechanism further comprises a center ring 4, which is hung at the middle position below the pulley 1, and the vertical rope 6 is arranged below the center ring 4, and the midpoint of the connecting piece one 7 is fixedly connected below the vertical rope 6, the hanging buckle 9 is connected with the wire rope 2, and the correction mark 5 is hung on the center ring 4.
[0026] One end of the connecting piece one 7 is fixedly connected with one end of the connecting piece two 8, and then connected with the hanging buckle 9 through the connecting circular ring.
[0027] The connecting member two 8 and the centering rope 6 are connected with the center ring through the connecting ring 10.
[0028] The connecting member one 7 is an elastic connecting member, and flexible materials with good elasticity such as rubber ropes can be used.
[0029] The connecting member two 8 is a non-elastic connecting member, and materials such as hemp ropes, iron rods or plastic rods can be used.
[0030] The correction mark 5 is hung on both sides of the centering rope 6, and one side of the correction mark 5 is provided with a ring one 5-1, and a ring two 5-2 is sleeved on the center ring 4 through the ring one 5-1, so as to ensure the freedom of the correction mark 5 during work.
[0031] The length of the correction mark 5 is shorter than that of the centering rope 6, so as to ensure that the correction mark 5 is not interfered by the centering rope 6 during work.
[0032] Figures 3-4 In the traditional way, the mold insert 11 is pulled up by a crane, it is difficult to calibrate the lifting angle of the crane, and the heights of the two toothed lifting rings installed in the lifting tooth are often different, F2-F1 is the lateral component of the mold insert in the left-right direction when the crane is pulled up, and F3 is the lateral component in the front-rear direction, this way causes that the lateral force of the mold insert 11 is very large when being lifted, because the lateral force is large, the friction and stress deformation between the mold insert 11 and the mold plate are further increased, the mold insert 11 is more difficult to pull up, sometimes causes the whole mold plate to slide laterally, still cannot pull out the mold insert 11, and even causes damage of the mold insert 11 or the mold plate.
[0033] When the present application is used, as shown in the figure, Figure 5 The connecting member two 8 slides through the center O through the connecting ring 10, the connecting member two 8 is a non-elastic connecting member with the same length, so that OAB can always be an isosceles triangle, the centering rope 6 is connected with the midpoint of the connecting member one 7, and the extension line of the centering rope 6 also intersects the center O. Even if the heights of the two lifting rings of the mold are not on the same horizontal line, the device can still automatically adapt and reduce the lateral component, and is not affected by the height difference of the lifting ring.
[0034] When operating, as shown in the figure, Figures 6-7 Only by controlling the movement of the crane, adjusting the coincidence of the centering rope 6 and the correction mark 5, and then lifting, the mold insert 11 can be vertically pulled up without lateral component.
