Technical Field
[0001] The utility model relates to a cable lifting device for a overhead crane sliding wire rack, belonging to the technical field of overhead crane equipment. Background Art
[0002] When the overhead crane is inspecting and replacing the cable of the cable tray, due to the heavy weight and special shape of the cable, as well as the harsh working environment on the overhead crane, the personnel have great difficulty in working, and the replacement time is sometimes too long, affecting the construction period. The cable may also be internally damaged due to violent pulling, which is difficult to detect until various problems occur during use, making it difficult to troubleshoot. At the same time, the personnel work for a long time and are prone to fatigue, which leads to safety accidents. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a cable lifting device for a crane sliding wire rack in view of the above-mentioned prior art, which saves the operation time of replacing the cable of the crane sliding wire rack, reduces cable dragging, prevents internal damage to the cable, and reduces the occurrence of safety accidents.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a cable lifting device for an overhead crane sliding wire frame, comprising two oppositely arranged columns, a cross beam is arranged between the two columns, a hanging ear is arranged at the bottom of the cross beam, a hand winch is hung on the hanging ear, and fixed feet are respectively arranged at the bottom of the columns, and the fixed feet are fixed to the cross beam of the overhead crane sliding wire frame.
[0005] The cable of the sliding wire rack is hung on the hook of the hand chain hoist through a sling.
[0006] The fixed feet respectively include a clamping foot, a through-length clamping groove is arranged at the bottom of the clamping foot, the clamping groove matches the cross beam of the overhead travelling carriage, and the clamping foot is locked to the cross beam of the overhead travelling carriage through a locking unit.
[0007] The locking unit comprises a locking screw, and locking screw holes are symmetrically provided on both sides of the clamping foot, and locking screws are respectively passed through the locking screw holes, and the two are threadedly connected; the locking screws are tightened to lock the clamping foot to the crossbeam of the overhead traveling crane sliding wire frame.
[0008] Compared with the prior art, the advantages of the utility model are: a cable lifting device for an overhead crane sliding wire rack, which is easy to operate, saves time and effort, saves the operation time of replacing the overhead crane sliding wire rack cable, reduces the dragging of the cable, prevents internal damage to the cable, and reduces the occurrence of safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of a cable lifting device for a overhead traveling crane sliding wire rack according to an embodiment of the utility model;
[0010] Figure 2 for Figure 1Schematic diagram of the fixed foot;
[0011] In the figure, 1 is a column, 2 is a hanging ear, 3 is a beam, 4 is a fixed foot, 4.1 is a clamping foot, and 4.2 is a locking screw. DETAILED DESCRIPTION
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown, a cable lifting device for a overhead traveling crane cable frame in this embodiment comprises two oppositely arranged columns 1, and a cross beam 3 is arranged between the tops of the two columns 1. A hanging ear 2 is arranged at the center of the bottom of the cross beam 3, and a hand chain hoist is hung on the hanging ear 2. Fixed feet 4 are respectively arranged at the bottom ends of the columns 1, and the fixed feet 4 are fixed to the cross beam of the overhead traveling crane cable frame.
[0014] The fixed base 4 includes a clamping foot 4.1, and a through-length clamping slot is provided at the bottom of the clamping foot 4.1. The width of the clamping slot matches the width of the cross beam of the overhead crane cable frame, so that the clamping slot is clamped on the cross beam of the overhead crane cable frame. Locking screw holes are symmetrically provided on both sides of the clamping foot 4.1, and locking screws 4.2 are respectively passed through the locking screw holes. The locking screws 4.2 are threadedly connected with the locking screw holes. The locking screws 4.2 are tightened so that the two locking screws 4.2 press against the cross beam of the overhead crane cable frame, that is, the clamping foot 4.1 is fixed on the cross beam of the overhead crane cable frame, and the clamping foot 4.1 is loosened to be unlocked.
[0015] The device is fixed upright on the crossbeam of the overhead crane sliding wire frame at the corresponding position and locked by locking screws. At the same time, a hand winch is hung on the hanging ear of the crossbeam. The sliding wire frame cable to be discharged is laid flat on the ground under the overhead crane sliding wire frame. Then the hand winch hook is lowered to hang the cable (to prevent the cable from being damaged by the hook, a short sling is used at the cable hanging point). The hand winch lifts the cable upward to the fixed end of the pulley, and then installs the cable tray on the pulley, and then loosens the hand winch to make the sliding wire frame cable fall exactly on the tray. Similarly, the cable of each pulley point is lifted into place one by one.
[0016] This application is easy to operate, saves time and effort, saves time for replacing the overhead crane sliding frame cable, reduces the dragging of the cable, prevents internal damage to the cable, and reduces the occurrence of safety accidents.
[0017] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
