Description
Technical field
The utility model relates to overhead traveling crane safety sliding contact line technical field, particularly relates to a kind of overhead traveling crane safety sliding contact line temperature compensation means.
Background technology
Sliding contact wire of overhead traveling crane, also known as trolley, slip, safety slide wire, safety sliding contact line, power for giving the equipment in moving, be made up of two parts, slide-wire guide rails (standing part, connect with power supply, conventional guide rail is formed by connecting by single long 4m/ root or 6m/ root), current-collector (slipper, can on slip track or interior slip and with copper bar contact electricity getting, current-collector is used for being connected with movable electrical appliances), the sliding contact wire of overhead traveling crane generally adopted at present has one pole to combine trolley, rigid sliding contact line, multi-level tubular trolley, without seam trolley, cable trolley and I-section steel cable pulley etc.
Sliding contact wire of overhead traveling crane environment for use is often more severe, particularly when large-sized workshop installation length is more than 150 meters, usually there is physical change because of variation of ambient temperature in trolley, often axiality is caused to be deteriorated because there is inhomogeneous deformation in process of expansion and contraction, when overhead traveling crane current-collector and trolley generation relative movement, easy generation hub is crossed over difficulty and causes the phenomenon of power-off, also spark phenomenon may be there is because contact-making surface diminishes, easily cause accident, have a strong impact on the safe operation of travelling overhead crane apparatus, and difficulty repaired by the trolley after distortion, integral replacing is needed after breaking down, increase maintenance cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of overhead traveling crane safety sliding contact line temperature compensation means; this device is arranged in the middle of sliding contact wire of overhead traveling crane; two fixed covers can relative sliding; when variation of ambient temperature causes trolley to be out of shape, two fixed covers in opposite directions or opposing motion, can offset deflection; avoid inhomogeneous deformation; guarantee the normal use of trolley, reduce maintenance cost, improve equipment safety in operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of overhead traveling crane safety sliding contact line temperature compensation means, comprise symmetrically arranged two fixed covers, for connect two fixed covers copper cash bundle and be fixedly mounted on two fixed cover opposite ends line of slide row, be fixedly mounted on two fixed cover opposite ends line of slide row between be slidably connected.
At least two pieces of uniform copper cash rows of in the vertical direction are drawn together in described line of slide package, the line of slide being arranged on two fixed cover opposite ends arranges mutual grafting, and be screwed installation, wherein the copper cash row of side is provided with chute, and the copper cash row of side above fixedly mounts the slide bolt be located in chute in addition.
Described copper cash bundle two ends are fixedly mounted on two fixed cover sides by means of line ball bolt respectively.
Described copper cash row is arranged in fixed cover by means of set bolt.
The beneficial effect adopting technique scheme to produce is: by installation fixed cover supporting with trolley, between fixed cover install can relative sliding copper cash row, and be connected and fixed cover with copper cash bundle, guarantee that whole trolley is normally communicated with, when the ambient temperature residing for trolley changes, this cognition of trolley produces a certain amount of distortion, existing trolley does not arrange compensation arrangement, distortional stress cannot evenly discharge, thus cause inhomogeneous deformation, and compensation arrangement of the present utility model be connected in the middle part of trolley after, disconnect position in the middle of trolley to be connected with fixed cover respectively, and two fixed covers can in the length range of chute in opposite directions or to be opposingly free to slide, trolley stress when being out of shape can be made evenly to be diffused, avoid inhomogeneous deformation, guarantee that trolley normally uses, improve safety in utilization, reduce overhead traveling crane maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be carry 1 upward view;
Wherein: 1, copper cash bundle; 2, line ball bolt; 3, copper cash row; 4, fixed cover; 5, set bolt; 6, chute; 7, slide bolt.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1-2, the utility model discloses a kind of overhead traveling crane safety sliding contact line temperature compensation means, comprise symmetrically arranged two fixed covers 4, for connect two fixed covers 4 copper cash bundle 1 and be fixedly mounted on two fixed cover 4 opposite ends line of slide row, be fixedly mounted on two fixed cover 4 opposite ends line of slide row between be slidably connected; At least two pieces of uniform copper cash rows 3 of in the vertical direction are drawn together in described line of slide package, the line of slide being arranged on two fixed cover 4 opposite ends arranges mutual grafting, and be screwed installation, wherein the copper cash row 3 of side is provided with chute 6, and the copper cash of side arranges the slide bolt 7 fixedly mounting on 3 and be located in chute 6 in addition; Described copper cash bundle 1 two ends are fixedly mounted on two fixed cover 4 sides by means of line ball bolt 2 respectively; Described copper cash row 3 is arranged in fixed cover 4 by means of set bolt 5.
In embody rule process, the utility model by relative to copper cash arrange folded insert group and become a transition body matched with trolley body sectional area, freely axial deformation can be carried out when trolley variation of ambient temperature, stretch in any case and shrink, the plane of a brush straight transitions of current-collector can both be given, thus the range of expansion overcoming comparatively early expansion pipe in period and bring is narrow, current-collector brush is crossed over difficulty and causes power-off and contact-making surface diminish and occur the faults such as sparking.
In a word, the utility model is by installation fixed cover supporting with trolley, between fixed cover install can relative sliding copper cash row, and be connected and fixed cover with copper cash bundle, guarantee that whole trolley is normally communicated with, when the ambient temperature residing for trolley changes, this cognition of trolley produces a certain amount of distortion, existing trolley does not arrange compensation arrangement, distortional stress cannot evenly discharge, thus cause inhomogeneous deformation, and compensation arrangement of the present utility model be connected in the middle part of trolley after, disconnect position in the middle of trolley to be connected with fixed cover respectively, and fixed cover can be free to slide in the length range of chute, trolley stress when being out of shape can be made evenly to be diffused, avoid inhomogeneous deformation, guarantee that trolley normally uses, improve safety in utilization, reduce overhead traveling crane maintenance cost.
