Abstract
The utility model discloses a welding-free type pulley wheel rope baffle device which comprises two support plates, wherein a rope baffle roller is installed between the upper parts of the support plates by shaft holes and baffle rings; and the middle of each support plate is provided with an installing hole capable of being covered on a pulley wheel shaft, and the lower end of each support plate is provided with a fork head capable of being in clamping connection onto a top arm section cross pipe. The support plates adopt a welding-free installation mode, so that the welding-free type pulley wheel rope baffle device is extremely simple and convenient to disassemble and assemble, cutting and welding working procedures are eliminated, the welding-free type pulley wheel rope baffle device is time-saving and labor-saving, the maintenance time can be reduced, the normal use of a crane can be guaranteed, the maintenance cost can be reduced, and the work efficiency can be improved. Meanwhile, the support plates of the device are welding-free structures, the support plates can be machined before being welded, and the plurality of support plates can be machined at the same time, and are easier to machine, so that the production time can be saved, the work efficiency can be improved, and the machining cost can be reduced. The welding-free type pulley wheel rope baffle device is simple in structure, resalable to design, and ingenious to design, and the blank of the devices can be filled, so that the welding-free type pulley wheel rope baffle device is wide to popularize and apply.
Description
One, technical field
The utility model belongs to the crawler crane corollary apparatus, is specifically related to a kind of welded type pulley ward off rope device of exempting from.
Two, background technology
For preventing that steel rope from deviating from from pulley groove, all be provided with ward off rope device on the pulley top of hoisting crane top arms joint.At present ward off rope device commonly used comprises two stay bearing plates, between the stay bearing plate top by axis hole and back-up ring mounting block rope roller.Two stay bearing plates adopt the mode of welding to be fixed on the axle sleeve of sheave shaft usually, and there is following weak point in this kind structure: 1, owing to adopting structure to weld, manufacturing procedure is loaded down with trivial details, and production efficiency reduces, and tooling cost is high; 2, dismounting difficulty, in case stay bearing plate in transportation or in using because the factors such as collision deform, then must again weld in the position of weld cutting, waste time and energy, inefficiency, maintenance time is long, have a strong impact on the normal use of hoisting crane, also increased maintenance cost.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, reasonable in design, handling ease, easy accessibility exempt from welded type pulley ward off rope device.
For achieving the above object, the technical solution adopted in the utility model is: this device comprises two stay bearing plates, by axis hole and back-up ring gear rope roller is installed between the stay bearing plate top; Be characterized in: the middle part of stay bearing plate is provided with the mounting hole that can be sleeved on the sheave shaft, and the lower end is provided with the jaw that can be connected on the top arms joint transverse tube.
During installation, the stay bearing plate of this device is placed pulley both sides on the top arms joint, to keep off the rope roller by axis hole and back-up ring is installed between the stay bearing plate top, again the jaw of stay bearing plate lower end is connected to carry out on the top arms joint transverse tube spacing, then sheave shaft is penetrated simultaneously on the mounting hole and pulley of stay bearing plate, two ends with sheave shaft are fixed on the axle sleeve at last, have finished whole installation process.During dismounting, finish above-mentioned anti-process and get final product.Because stay bearing plate adopts the mounting means of non-welding, dismounting is very simple and convenient, has saved and has cut again welding sequence, and is time saving and energy saving, reduced maintenance time, guaranteed the normal use of hoisting crane, reduced maintenance cost, improved work efficiency.Simultaneously, because the stay bearing plate of this device is non-welded structure, can process before the welding, and a plurality of stay bearing plate can process simultaneously, it is comparatively easy to process, and has saved production time, has improved work efficiency, has reduced tooling cost.The utility model is simple in structure, reasonable in design, is skillfully constructed, and has filled up the blank of such device, is worth applying widely.
Four, description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model stay bearing plate.
Five, the specific embodiment
As shown in the figure, this device comprises two stay bearing plates 3.By axis hole 3-1 and back-up ring 2 gear rope roller 1 is installed between stay bearing plate 3 tops.The middle part of stay bearing plate 3 is provided with the mounting hole 3-2 that can be sleeved on on the sheave shaft 7 that pulley 8 is installed, and its lower end is provided with and can be connected to top arms and saves jaw 3-3 on 9 transverse tubes 4.The two ends of sheave shaft 7 are fixed on the axle sleeve 5 by bolt 10, and axle sleeve 5 is fixed on the top arms joint 9 by connecting panel 6 again.
