Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rolling mill equipment installation, in particular to a hanger for a thick plate rolling mill frame. Background Art
[0002] The appearance of a rolling mill frame is usually composed of upper and lower crossbeams and left and right columns, forming a frame-like structure. However, due to its large size and heavy weight, the thick plate rolling mill frame must be transported horizontally. Its upright turning and installation are very difficult, and generally require the use of special lifting equipment to assist in lifting. Currently, the commonly used lifting equipment is not only complex in structure, but also mostly uses clamps to lock the two sides of the rolling mill frame to achieve the upright turning and horizontal lifting of the rolling mill frame. Due to installation errors and insufficient friction between the clamps on both sides, this lifting method is prone to causing the rolling mill frame to slip when turning over, and even accidents such as unstable center of gravity and rollover, posing a significant safety hazard. Utility Model Content
[0003] The main purpose of the utility model is to propose a hanger for a thick plate rolling mill frame, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0005] A hanger for a thick plate rolling mill frame, comprising
[0006] Two splints, set opposite to each other;
[0007] Two hanging plates are detachably fixed to the two ends of the two clamping plates, and the outer sides of the hanging plates are provided with hanging ears;
[0008] A support frame is detachably fixed on the top of the two clamping plates, and the support frame includes
[0009] The support base is an I-shaped structure, with both ends being detachably fixedly connected to the two clamping plates;
[0010] Two supporting columns are fixed on both sides of the top of the supporting base;
[0011] The supporting crossbeam is fixed on the top of the two supporting columns.
[0012] Preferably, it also includes
[0013] A raising pad is fixed to the top of the supporting beam.
[0014] Preferably, the heightening pad is higher in the middle and lower at both ends, and the lower ends are used to be fixedly connected to the supporting beam by bolts.
[0015] Preferably, connecting plates are fixed to the bottoms of both ends of the support base for fixed connection with the clamping plates via bolts.
[0016] Preferably, the lifting lug is a straight rod, which is vertically fixedly connected to the hanging plate, and the outer side of the lifting lug is fixedly connected to the hanging plate through a plurality of stiffening plates.
[0017] The utility model provides a hanger for a thick plate rolling mill frame, which has the following beneficial effects:
[0018] When the hoist is in use, the two clamps are placed on the front and rear sides of the thick plate rolling mill frame respectively, and then the two ends of the two clamps are connected by hanging plates to clamp the thick plate rolling mill frame. The support frame is then fixed on the top of the two clamps. The support frame is used to support the inner top of the thick plate rolling mill frame. After the installation is completed, the lifting ears on the outside of the hanging plates are used as lifting points to connect them with the lifting ropes. After lifting, the thick plate rolling mill frame is lifted from horizontal to vertical, and subsequent horizontal lifting and installation are realized. During the lifting process, since the thick plate rolling mill frame is clamped between the two clamps and the inner top of the thick plate rolling mill frame is supported by the supporting crossbeam, the lifting is stable, and there will be no slipping or tipping, thereby ensuring lifting safety.

[0041] The heightening pad 5 is fixed on the top of the supporting beam 33 . A heightening pad 5 of appropriate height can be fixed on the supporting beam 33 according to the distance between the supporting beam 33 and the top of the plate rolling mill frame.
[0042] In a specific embodiment, the heightening pad 5 is high in the middle and low at both ends, and the low ends are used to be fixedly connected to the supporting beam 33 by bolts.
[0043] In a specific embodiment, connecting plates 6 are fixed to the bottoms of both ends of the support base 31 for fixed connection with the clamping plate 1 via bolts.
[0044] In a specific embodiment, the lifting ear 4 is a straight rod, which is vertically fixed to the hanging plate 2. The outer side of the lifting ear 4 is fixed to the hanging plate 2 through a plurality of stiffening plates 7 to ensure the connection strength between the lifting ear 4 and the hanging plate 2.
