Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane rail maintenance technology, and in particular to a portable mobile operation device for the maintenance of aerial work tracks and sliding rails. Background Technology
[0002] Taking Xichang Steel and Vanadium Plate Plant as an example, the crane rails in the cold zone alone consist of: raw material spans 1, 2, 3, and 4; pickling and rolling production spans; post-pickling and rolling spans 1 and 2; grinding roll spans; continuous annealing production spans; finished product spans 1, 2, 3, and 4; and hot pickling production spans. There are a total of 14 crane rails. Therefore, the maintenance of these crane rails is very frequent. Since the crane rails are all at a height of over eight meters, each rail has one side exposed to the air and the other side protected by safety railings. All rail maintenance work requires attaching safety belts to the safety railings.
[0003] Since all safety railings need to be supported by columns, the safety belts can be blocked by the columns when repairing crane rails. For example, when tightening the bolts on the crane rail pressure plate or when marking and repairing the rails, workers need to move around in the air. In this case, double-hook safety belts must be used to be alternately attached to the safety railings on the side of the rail.
[0004] Crane rail maintenance is divided into electrical personnel inspecting the sliding rails and mechanical personnel inspecting the rails. The main tasks for electrical personnel include tightening the sliding rail bolts, checking and tightening the connecting plates between the sliding rails, replacing damaged parts, and cleaning the sliding rails. The main tasks for mechanical personnel include tightening the rail bolts, checking and repairing the pressure plates, and checking and repairing the shims.
[0005] Due to the obstruction of the safety railing posts, personnel need to constantly unfasten and refasten their safety belts when moving, then move forward and fasten them again inside the safety railing. This frequent back-and-forth exchange of double-hook safety belts is extremely inconvenient and inefficient. In addition, the continuous alternation of safety belt fastening can cause certain safety hazards if the belts are not fastened properly. Summary of the Invention
[0006] To address the aforementioned problems, the purpose of this utility model is to provide a portable mobile work device for the maintenance of aerial work tracks and sliding lines, which can effectively solve the problem of safety belt fastening. Firstly, it can save time for track and line marking maintenance; secondly, it can reduce the labor load of personnel; and thirdly, it can reduce the safety hazards caused by personnel repeatedly disassembling and fastening safety belts.
[0007] The technical solution adopted in this utility model is as follows:
[0008] This utility model discloses a portable high-altitude crane track and sliding rail maintenance mobile operation device, comprising two rectangular frames, two connecting rods, a limiting rod, two pulleys, and two concave connecting parts; the two rectangular frames are arranged parallel and symmetrically at a certain distance; the left and right ends of the top of the two rectangular frames are respectively fixedly connected by a connecting rod; the limiting rod is fixedly connected between the tops of the two connecting rods; the two concave connecting parts are respectively installed on both sides of the bottom of the limiting rod and are symmetrical to each other; the pulleys are respectively rotatably connected between the two ends of the concave connecting parts.
[0009] Furthermore, the rectangular frame is welded from DN25 steel pipes.
[0010] Furthermore, the vertical distance between the two rectangular frames is 68-72mm.
[0011] Furthermore, the rectangular frame has a length of 780-820mm and a width of 180-220mm.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This utility model has a simple structure, is easy to use, and is safe and applicable. During maintenance, it can move on the safety railing, and only requires fastening the safety belt once to complete the maintenance of a whole span of crane track and marking, which can significantly shorten maintenance time. At the same time, the manufacturing cost is low, which can effectively improve work efficiency, save a lot of labor costs, and has significant economic and social benefits.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0018] It should be noted that in the description of this utility model, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.
[0019] like Figure 1-2 As shown, the portable high-altitude crane track and sliding line maintenance mobile operation device proposed in this utility model includes two rectangular frames 1, limiting rods 2, two pulleys 3, two concave connecting parts 4, and two connecting rods 5.
[0020] Two rectangular frames 1 are arranged opposite each other at a certain distance, and are parallel and symmetrical to each other. The top left ends of the two rectangular frames 1 are fixedly connected by a connecting rod 5, and the top right ends of the two rectangular frames 1 are fixedly connected by another connecting rod 5. The limiting rod 2 is fixed between the middle of the top ends of the two connecting rods 5, and the limiting rod 2 is parallel to the top edge of the rectangular frame 1 and perpendicular to the connecting rod 5. Two concave connecting pieces 4 are respectively vertically fixed on both sides of the bottom of the limiting rod 2, and are parallel and symmetrical to each other. The pulleys 3 are respectively rotatably connected between the two ends of the concave connecting pieces 4, and are parallel and symmetrical to each other.
[0021] In this embodiment, the rectangular frame is welded from DN25 steel pipes. The length of the rectangular frame 1 is 780-820mm, preferably 800mm, and the width of the rectangular frame 1 is 180-220mm, preferably 200mm. The vertical distance between the two rectangular frames is 68-72mm, preferably 70mm.
[0022] In operation, this invention simply requires the device to straddle the safety railing, with the two pulleys 3 rolling into contact with the top horizontal bar 7. During operation, the safety belt is attached to the limiting bar 2, allowing the worker to walk along the entire passageway. Simultaneously, the device slides along the safety railing with the worker, guided by the pulleys 3. There is no need for manual unfastening or fastening of the worker's safety belt. If a worker accidentally falls from the suspended side, the device will tilt, and the rectangular frame 1 will be stopped by the horizontal bar 7 in the middle of the safety railing. Both the device and the worker wearing the safety belt will remain firmly attached to the safety railing, thus ensuring the worker's safety.
