Description

Technical Field

[0001] The utility model relates to the technical field of safe operation equipment of a dry coke quenching hoist hook, in particular to a guide structure for a dry coke quenching tank lifting lug. Background Art

[0002] The dry quenching coke elevator is an automatic lifting device. When the electric locomotive delivers a full tank of about 22 tons of red coke to the APS±50mm in the elevator shaft, the electric locomotive sends a full tank signal. After receiving the signal, the elevator starts to lift automatically. The elevator hook is aligned with the coke tank lifting lug and automatically hooks. If the coke tank rotates to receive the red coke and stops rotating after receiving it, and there is a slight deviation in the rotation stop position, it will easily cause one side of the hook to be unhooked and the full tank of red coke to fall over. How to ensure that the hook can accurately hook the lifting lug in the event of an error in the APS or the rotation of the coke tank is an urgent problem to be solved. Utility Model Content

[0003] The purpose of the utility model is to provide a guide structure for the lifting lug of a dry quenching coke drum in view of the above situation, which realizes automatic correction of the alignment when the alignment of the coke drum is deviated and the hook and the lifting lug are offset, thereby avoiding the danger of the hook offset and overturning the coke drum.

[0004] The specific scheme of the utility model is: a guiding structure for the dry quenching coke tank lifting ear, comprising an ear shaft body, two lower guide plates are symmetrically arranged at both ends of the ear shaft body facing downward, a front guide plate is also arranged forward on the upper parts of the two lower guide plates, the two front guide plates are arranged oppositely, and the two front guide plates are arranged outwardly in an outward eight-shaped shape.

[0005] Furthermore, a reinforcing rib plate is welded between the outer side wall of the front guide plate and the corresponding lower guide plate in the utility model.

[0006] Furthermore, the shape of the lower guide plate in the utility model is narrow at the top and wide at the bottom, and the lower end edge of the lower guide plate is arranged outwardly to form an arc-shaped outer flange structure.

[0007] Furthermore, the lower guide plate and the end of the ear shaft body in the utility model are locked by using a locking nut.

[0008] Furthermore, the front guide plate in the utility model is butt-welded to the upper side of the corresponding lower guide plate into one piece.

[0009] The utility model aims at the situation that the dry coke quenching coke drum is not properly hooked when it is lifted and hung, and realizes automatic guided alignment when the coke drum has deviation in alignment and the hook and the lifting ear are offset, effectively avoiding the danger of the offset hook pulling over the coke drum; the whole structure is simply improved, the practicability is strong, and the actual use and promotion value are obvious.

[0015] The following will be combined with the accompanying drawings of the utility model to clearly and completely describe the technical solution of the utility model. It is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. In the description of the utility model, it should be noted that the terms "upper", "lower", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when used, which is only for the convenience of describing the utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] See also Figures 1 to 3The utility model is a guide structure for the ear of a dry quenching tank, which has an ear shaft body 3, and two lower guide plates 4 are symmetrically arranged downward at both ends of the ear shaft body. A front guide plate 1 is also arranged forward on the upper part of the two lower guide plates, and the two front guide plates are arranged opposite to each other, and the two front guide plates are arranged outward in an outward eight-shaped shape. Further, a reinforcing rib plate 2 is welded between the outer side wall of the front guide plate and the corresponding lower guide plate in the utility model. Further, the shape of the lower guide plate described in the utility model is narrow at the top and wide at the bottom, and the lower end edge of the lower guide plate is arranged outward to form an arc-shaped outer flange structure. Further, the lower guide plate described in the utility model and the end of the ear shaft body are locked by a locking nut 6. Further, the upper side of the front guide plate described in the utility model and the corresponding lower guide plate are butt-welded into one.

[0018] The utility model is made as follows:

[0019] (1) Use 16mm thick steel plate to make two 200*300mm outer eight-shaped pieces, which are welded on both sides of the ear shaft body to form an outer eight-shaped shape, thereby increasing the guiding distance of the lifting hook to the front of the lifting ear; In addition, use 16mm steel plate to make two outer eight-shaped pieces with lower flanges, which are also welded on both sides of the ear shaft body facing downwards, thereby increasing the guiding distance of the lifting hook to the bottom of the lifting ear.

[0020] (2) A reinforcing rib plate is welded on the outer side of the outer horn of the front guide plate. When the hook needs the front guide plate to correct its direction, the hook will be retracted inward along the horn opening, and the hook will be biased toward one side of the horn plate. The friction force is relatively large, and the hook is guided along the horn plate to the center of the ear shaft body, avoiding the risk of the hook being offset and pulling over the coke drum. When the hook moves upward from the bottom, the lower guide plate increases the guiding distance of the hoist hook to the bottom of the lifting ear and guides the hook to the center of the ear shaft body, avoiding the risk of deviation.

[0021] When the hook and the ear shaft body are accidentally misaligned, the hook slides along the front guide plate or the lower guide plate to correct the center line of the hook and the ear. When the hook is lifted, it just hooks the ear (i.e. the ear shaft body).

[0022] The utility model aims at the situation that the dry coke quenching coke drum is not properly hooked when it is lifted and hung, and realizes automatic guided alignment when the coke drum has deviation in alignment and the hook and the lifting ear are offset, effectively avoiding the danger of the offset hook pulling over the coke drum; the whole structure is simply improved, the practicability is strong, and the actual use and promotion value are obvious.
