Abstract
The utility model discloses an insulating tie rod of a railway rail. A thread through hole the length of which is larger than the diameters of a main screw and an auxiliary screw is arranged in an outer sleeve of the insulating tie rod. An injection piece, the outer sleeve, the main screw and the auxiliary screw are connected by injection into one body. The injection piece is provided with a middle wall which is insulated and isolated from the end surfaces of the main screw and the auxiliary screw. The outer sleeve is insulated and isolated from the main screw and the auxiliary screw by sleeve barrels which are arranged at the left side and the right side of the injection piece. The utility model has the advantages of simple structure. The utility model cancels pin fixing connection between the auxiliary screw and the outer sleeve, enhances strength and substantially raises production efficiency. The utility model is made in one-step injection molding. The utility model can be used on rails of railways and subways.
Description
The utility model relates to a kind of insulating distance-keeping rod for steel rails of rail way.
Insulated gage rod has gauge, the hardened link effect that keeps two rail, is one of railway traffic very important components.The product (Fig. 2) that used rail insulation tie rod is a eighties.The original types of attachment such as still adopting nut, gib that is connected of the outer end of insulated gage rod and rail.Pay screw rod and overcoat for being threaded.For preventing to become flexible, pass overcoat 2 and pay screw rod 5 both fixed-site with pin 6.Causing overcoat and the strength reduction of paying screw rod dress pin place, is the weak link of insulated gage rod.Structure is complicated.Processing capacity is big, and the production cycle is longer.
The purpose of this utility model is to provide a kind of insulating distance-keeping rod for steel rails of rail way for overcoming above-mentioned weak point, injects the integral body that engineering plastics are fixedly connected as overcoat, driving screw, pair screw rod one mutual insulating by injection machine.Simple in structure, good insulation preformance.
The utility model content: a kind of insulating distance-keeping rod for steel rails of rail way, comprise driving screw, pay screw rod and overcoat, main, a pair screw rod two ends car has screw thread, it is characterized in that: be provided with tapped through hole in the overcoat greater than master, pair screw diameter, moulding and overcoat, driving screw, a pair screw rod injection moulding connect as one, moulding is provided with insulation and isolates middle walls main, that pay the screw rod end face, and the moulding and arranged on left and right sides is respectively equipped with overcoat and master, pays the screw rod sleeve that insulation is isolated.Described overcoat, driving screw, a pair screw flight are left-hand thread or right-hand thread or left and right screw thread chi structure.
The utlity model has following advantage:
Insulating distance-keeping rod for steel rails of rail way overcoat, master, pay a screw rod and be connected as a single entity through the injection moulding of high-pressure injection moulding machine, saved pin and brill, hinge pin hole operation etc., simple in structure, reduced cost, improved intensity.
2. the utility model uses the engineering plastics injection moulding, and engineering plastics are nontoxic to health, be beneficial to engineering plastics that environmental protection injects overcoat, driving screw, pay the screw rod space from, insulating properties are reliable.
Description of drawings:
Figure l is the utility model structural representation;
Fig. 2 is for now using the insulated gage rod structural representation.
Further specify the utility model below in conjunction with drawings and Examples.
Insulating distance-keeping rod for steel rails of rail way (Fig. 1) is made up of driving screw l, overcoat 2, moulding 4 and a pair screw rod 5.Overcoat is installed on the support at anchor clamps middle part, and main, a pair screw rod is installed in respectively on the traversing carriage of anchor clamps and arranged on left and right sides, and anchor clamps guarantee that overcoat and left and right screw rod are centered close on the same straight line; Traversing carriage is moved to the centre, make the about 4mm of distance between main, as to pay screw rod inner end, the high-pressure injection moulding machine injects Merlon, so just overcoat, master, pay a screw rod and be connected as a single entity and form moulding 4,3 end face insulation main, that pay screw rod of the middle walls of moulding are isolated, and the cylinder of moulding both sides is isolated overcoat and master, a pair screw rod insulation respectively.For improving the bond strength of engineering plastics (Merlon) and overcoat, driving screw, pair screw rod, be shaped in the external trepanning and be left-hand thread and right-hand thread, left and right screw thread crosses one another, so the bonded area of overcoat and engineering plastics doubles, adhesion is big, can not get loose.Inner end main, that pay screw rod also is shaped on left and right screw thread, plays a part to increase adhesion equally and can not get loose.Owing to removed the connection pin, also do not needed pin hole processing on overcoat and pair screw rod, so improved intensity.
Claims (2)
1. insulating distance-keeping rod for steel rails of rail way, comprise driving screw, pay screw rod and overcoat, main, a pair screw rod two ends car has screw thread, it is characterized in that: be provided with tapped through hole in the overcoat greater than master, pair screw diameter, moulding and overcoat, driving screw, a pair screw rod injection moulding connect as one, moulding is provided with insulation and isolates middle walls main, that pay the screw rod end face, and the moulding and arranged on left and right sides is respectively equipped with overcoat and master, pays the screw rod sleeve that insulation is isolated.
2. insulating distance-keeping rod for steel rails of rail way as claimed in claim 1 is characterized in that: described overcoat, driving screw, a pair screw flight are left-hand thread or right-hand thread or left and right screw thread chi structure.
