Abstract
The invention relates to a fixing device with a locking frame and a heating strip. The device comprises an upper fixing clip and a lower fixing clip which are matched with the locking frame in shape, are elastic, and together wrap the locking frame respectively from top and bottom, the heating strip abutted to the locking frame is fixedly arranged at the inner side of the lower fixing clip, the two fixing clips are buckled, the buckled parts are provided with locking pieces, each locking piece consists of a convex middle part, corresponding two ends positioned in the length direction of the middle part, and two straight ends integrated with the middle part, the middle parts are provided with positioning grooves along the length directions, the front locking piece and the back locking piece are arranged back to back in a paired mode, and the upward and downward movement of the upper fixing clip and the lower fixing clip is limited elastically by a transitional slope of the convex middle parts. According to the fixing device disclosed by the invention, the paired elastic locking pieces and the buckled upper fixing clip and lower fixing clip are matched, so that the weight of the device is greatly reduced, clamping force is increased, and a severe test on a structure and material thereof caused by alternating heavy dynamic load and temperature upheaval is buffered.
Description
Technical field
The present invention relates to fixing locking frame fire-bar structural element for a kind of railway.
Background technology
External locking device is the important safety link in railway switch conversion equipment, is made up of, for the reliable state that keeps track switch locking bar, locking frame, lock locking iron, latch hook and switch rail connection iron etc.
Melting snow on turnout junction technology is intended to prevent that tongue from being frozen by ice and snow, and the mode that fire-bar or heating panel are installed in common employing below external locking device reaches the object of timely snow melt.
The composite member of tradition Fixed frog external locking frame elastic fixing clamp is with complicated machining process part or the complete fastening fire-bar of material irrational mix part, entirety heaviness or fault of construction, process structure complexity, excessively positioning phenomenon is serious, once there is jump in temperature and hand over frequently heavy dynamic load, can occur that crackle even ruptures at structural weak place, directly cause heater to lose efficacy and even occur even more serious consequence.
Summary of the invention
The defect existing for overcoming background technology, the invention provides a kind of structure simple and clear, the locking frame fire-bar fastening devices that own wt is lighter.
Basic technical scheme of the present invention is as follows:
Locking frame fire-bar fastening devices, comprises and the flexible upper fixed card of having of locking frame shape adaptation and lower fixed card, forms coated to locking frame respectively from upper and lower is common, is installed with the fire-bar of being close to locking frame in the inner side of lower fixed card; Left and right the same side end of two fixed cards is interlockingly connected respectively, is provided with and has flexible forward and backward stay in both sides snapping portion; Two staies are en plaque, and by protruding mid portion and be positioned on described mid portion length direction corresponding two ends and form with two flat end that described middle part is integrated, described mid portion offers locating slot along its length; The opposing paired setting of front stay and rear stay, connects by bolt assembly, the locating slot a certain side of the mounting hole site of bolt assembly in described mid portion plane; Described snapping portion cross-under locating slot, by moving up and down of the upper and lower fixed card of transition inclined-plane elastic limit of protruding mid portion.
Based on above-mentioned basic technical scheme, the present invention also carries out following optimization and limits and improve.
The end of fixed card and lower fixed card is the flush end that right angle is bent to form, the parallel described snapping of the formation portion that interlocks of these two flush ends, the right angle adjacent segments difference front stay of cross-under of these two flush ends and the locating slot of rear stay.
Described bolt assembly comprises soket head cap screw and adaptive captive nut and packing ring.
The top of fixed card has downward arc arch face.
The present invention has the following advantages:
In the present invention, paired flexible locking piece and the upper and lower fixed card mating reaction interlocking, greatly reduce own wt, increased clamping dynamics, cushioned the heavy dynamic load of alternation and jump in temperature and caused the baptism to structure and material thereof.
The present invention has simple and reasonable, easy for installation, clamp solid and reliable, the advantage that own wt is lighter.Use material all to carry out reliable metal heat treatmet and surfacing, anticorrosive, temp. variation resistant is very capable.
Brief description of the drawings

Fig. 2 is front section view of the present invention.
Fig. 3 is lateral view of the present invention.
Fig. 4 is the structural representation of upper fixed card of the present invention.
Drawing reference numeral explanation:
The upper fixed card of 1-; Fixed card under 2-; 3-locking frame; 4-fire-bar; Stay before 5-; Stay after 6-; Hexagonal stainless steel screw in 7-;
Locating slot on 8-stay; The blunt end part that the end of 9-fixed card is bent to form with right angle; The right angle adjacent segments (this right angle adjacent segments cross-under locating slot) of 10-" 9 " blunt end part.
Detailed description of the invention
As shown in Figures 1 to 4, the position that upper and lower fixed card of the present invention is interlockingly connected is provided with to clamp the front and back stay of fastening locking frame, locking frame fire-bar fastening devices is to use to be subject to jump in temperature and buffering alternation dynamic load to affect less elastic leaf springs material, make it form a spring chamber, the internal stresses release of having considered the each bending part occurring in process while simultaneously design has rational circular arc excessive, be conducive to improve structural strength, strengthen clamping fastening force, regulate easy for installation; Making to be more suitable for on-the-spot locking frame fire-bar fixes.
In order to prevent occurring even deviation phenomenon of displacement having the locating slot of fixing its displacement on locking plate in upper lower clip clamping process, ensure that clamp only has the resilient clamp of vertical direction to move; Can make chucking power more reliable, resilient arch concavity in the time that upper clip designs, makes can produce a more rational predetermined chucking power in fixation procedure simultaneously.
Along with front and back locking plate is to the movement in centre position, locking plate can constantly strengthen the pressure to upper and lower fixation clamp, it is characterized in that with inner hexagon spanner in the process of connection M6 × 30 and M6 captive nut, make to open locking plate subtract low-angle simultaneously discharge at elastic force, pull lower clip to draw direction distortion separately, thereby strengthen clamping locking frame and fire-bar dynamics.
Mounting process of the present invention:
1 installs front preparation
1.1 are installed on special locking frame fire-bar in lower fixed card.
Spring locking plate inner side after 1.2 2 of M6 dedicated nuts are installed on respectively 2.
2. installation steps
2.1 are firmly installed separately fixed card under locking frame in locking frame bottom side to both sides.
Under 2.2 locking frames that install special fire-bar, fixed card pushes away on firmly and keeps bottom and locking frame closely connected.
2.3 upper fixed cards are firmly separately enclosed within lower fixed card, and keep side concordant from front to back to both sides.
2.4 rear spring locking plate, front spring locking plate lockings that mounted upper fixed card, lower fixed card use assemble.
When 2.5 locking, notice that M6 screw adds the self-locking gasket of M6, tighten with inner hexagon spanner.
The present invention, compared with traditional fixed component, has used leaf spring flexible member and structure design cleverly, has that clamping is solid and reliable, process structure simple, is convenient to on-the-spotly install, the firm advantage such as durable, overcomes the defect of conventional fixation means.
