Abstract
The utility model discloses a bolt-type rail fixing sleeper, which comprises a sleeper seat and two rail fixing devices, wherein the sleeper seat is prefabricated by concrete; and the two rail fixing devices are respectively and fixedly connected at two ends of the sleeper seat in a preset mode, and each rail fixing device comprises a base and a pressure plate. The bolt-type rail fixing sleeper is characterized in that two bosses are arranged on the base of each rail fixing device; and inverted T-shaped grooves are arranged on the bosses, and each pressure plate is fixedly connected on the bosses by fastening bolts inverted in the T-shaped grooves. According to the bolt-type rail fixing sleeper, the pressure plates are fastened in a bolt fastening mode; the fastening is relatively reliable; the pressure plates can not loose due to long-term vibration; and each inverted T-shaped groove structure is convenient to enable the fastening bolt to place in, and simultaneously, the fastening speed is fast. The bolt-type rail fixing sleeper is convenient to mount and dismount a steel rail, can greatly improve the work efficiency, and removes potential safety hazards in production.
Description
Technical field:
The utility model relates to a kind of sleeper of fixedly railway track, the sleeper that particularly a kind of mine uses down.
Background technology:
At present, the sleeper that uses on the railway is mostly for being provided with the concrete sleeper of solid rail device, Gu the rail device is affixed through the mode and the concrete sleeper that preset.Said solid rail device is produced with track down for mine; Be the solid rail device of trip type mostly, wherein a kind of rectilinear card is fixed to the rail device and comprises base, press strip and card wedge, and leg is arranged at the bottom of said base; Leg is preset in the concrete sleeper affixed with sleeper; Base is provided with the press strip hole of horizontal direction, and press strip is arranged in the press strip hole, has the press strip wedge hole that vertical direction and card wedge match on the said press strip; Said card wedge is through in the press strip wedge hole, and the face and the base on one face and the applying of press strip wedge hole, opposite are fitted.The card wedge that this vertical direction is provided with, because of there not being other object near its head, thereby when rail is installed; Setter uses hammer to exert oneself well, be easy to impact, and is convenient to install and be prone to make the card wedge to put in place, simultaneously; Card wedges and is equipped with positive stop lug boss and card wedge cap, during dismounting, the instrument of one type of ripping bar is placed between card wedge cap and the base; A little firmly prize, can will block wedge and take apart from base.Though this solid rail device is convenient to installation and removal; But the mode of the fastening press strip in card wedge this dependence inclined-plane is relatively poor to the tolerance degree of vibrations, is working under the vibration environment for a long time; Be easy to generate looseningly, thereby this sleeper brings certain hidden danger to safety in production in actual use.
Summary of the invention:
The purpose of the utility model is the deficiency that overcomes prior art, provides a kind of and is convenient to installing/dismounting, is difficult for the solid rail sleeper of loosening bolt type simultaneously.
The technical scheme that realizes the utility model is, the solid rail sleeper of a kind of bolt type comprises sleeper seat and solid rail device, and said sleeper seat is by concrete prefabricated, and said solid rail device is two, is fixed in sleeper seat two ends through the mode that presets respectively; Said solid rail device comprises base and pressing plate, it is characterized in that the base of said solid rail device is provided with two boss, and said boss is provided with inverted T-shape groove; Said pressing plate is fixed in it on boss by the fastening bolt that is through in the inverted T-shape groove.
The utility model adopts the mode of bolton to come clam member, and with respect to the solid mode of card wedging, fastening is more reliable; Pressing plate can not become flexible because of shaking for a long time, and inverted T-shape groove structure is convenient to inserting of fastening bolt; And through bolt moving in groove, the seal face of press strip and rail can be coincide better, simultaneously easily; Only need when T-shape groove structure makes fastening bolt the nut action need not fixed screw rod, fastening speed is fast.The utility model is simple in structure, is convenient to the installation and removal of rail, can increase substantially operating efficiency, and eliminates the potential safety hazard in producing.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
Accompanying drawing 2 is left views of Fig. 1, and projection section is analysed and observe processing among the figure.
Label among the figure: 10 bases, 11 gussets, 12 legs, 13 boss, 14 T-shape grooves, 20 fastening bolts, 30 rail, 40 pressing plates, 41 grooves, 42 pressure heads, 50 sleeper seats.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the width between two boss 13 that are provided with on the said base 10 between the interior surface opposing equals or is slightly larger than the width of rail 30 bottom sections, and the fluting direction of inverted " T " shape groove 14 is vertical with the longitudinal axis of rail 30.Said pressing plate 40 cross sections are
shape; Comprise plate body and pressure head 42, the shank of the underside shape of said pressure head 42 and rail 30 coincide; The position of pressing plate 40 and boss 13 applyings has groove 41, acts on fully on the rail 30 to guarantee the fastening force of pressing plate 40 when fastening; Pressing plate 40 is fixed in it on boss 13 by the fastening bolt 20 that is through in the inverted T-shape groove 14.Said base 10 is provided with four legs 12, places to be provided with between two legs on rail 30 2 limits to strengthen gusset 11, and leg 12 is preset in the concrete sleeper seat 50 affixed with sleeper seat 50.
