Abstract

The utility model discloses a railway insulating crowbar which comprises a U-shaped crowbar head and a crowbar handle. The U-shaped plane of the crowbar head is perpendicular to the crowbar handle, a hammer is further fixedly connected at the tail end of the crowbar handle, the crowbar handle is a long straight rod composed of a crowbar handle head and a crowbar handle tail which can be detachably connected, the end face, opposite to the crowbar handle tail, of the crowbar handle head is provided with a blind hole, and an insulating rod is inserted into the blind hole. The railway insulating crowbar is simple in structure, convenient to use, reliable in insulating performance and good in spike removal effect and can be widely applied to common wood sleeper lines and wood sleeper turnouts, spike removal pads are not required during railway maintenance operation, work efficiency is improved, and safety, time and labor saving and high efficiency are achieved. Additionally, the hammer can be used for hammering when needed.

Description

The railway Insulation crowbar

Technical field

The utility model relates to a kind of railway crowbar, particularly relates to a kind of railway Insulation crowbar.

Background technology

Crowbar use in the rail track upkeep operation is a lot; Existing crowbar in use can carry out rail and stir; Sleeper location track lining changes its course, rises railway spike or transforms the bar cooperation and correct gauge etc.; But in the specific operation process of maintenance line, run into some problems: the head camber of existing crowbar can only be suitable for common sleeper track remodelling and play railway spike and the railway spike operation of the sleeper bridge outside, is not suitable for the railway spike operation between guard rail of bridge and the circuit rail small space; Also need the nail nipping pad simultaneously and cooperate normally nail nipping, use very inconvenient.Because on the existing railroad bridge that uses; The line track inboard generally all is equipped with guard rail, and the distance between guard rail and the circuit rail head of rail is 200mm, in the circuit maintenance process; When playing railway spike with crowbar and push downwards; Guard rail can block the crowbar bar can not bring into play the leverage of crowbar head, has hindered the normal use of crowbar, can only turn over an angle of 90 degrees and utilize the nail nipping again of track shade along orbital direction.Because the widest part has only 8mm between railway spike bar limit to the head of a nail limit; The narrowest being in about 5mm, and be that arc line type is connected between nail bar and the head of a nail, the crowbar head and the head of a nail are along the generation skidding when causing crowbar to play railway spike easily; Also can therefore cause operating personnel's tumble injury accident when serious; Run into the railway spike of corrosion, sometimes in addition a few minutes all rise not nextly, cause that operation is dangerous, time-consuming, effort, efficiency be low.

In addition, in the prior art, when preventing that track circuit from pulling out railway spike or track lining operation because of rising with crowbar,

With the collision of two one steel rails, just caused the track circuit short circuit to destroy once in a while, generally adopted the method for suit rubber tube to insulate in the crowbar outside.Another kind is to twine rubber by rubber plant on the crowbar surface, after vulcanizing treatment, forms rubber sleeve.All there is certain problem in these two kinds of insulation sleeves, and the former can't tightly be enclosed within on the crowbar because of gum cover, and gum cover often comes off in the use; The latter needs rubber plant to process specially, and processing charges is high, and can only be used for railway spike; Can not be used for track lining, the quantity of having increased the instrument that carries for the railway maintenance personnel, the frequent and rail bump of crowbar in the use; Gum cover is crashed through insulating layer soon and is destroyed, and continues to take place the track circuit short circuit and destroys.

The utility model content

In order to address the above problem; The utility model provides a kind of railway Insulation crowbar; Overcome that the operation between sleeper guard rail and circuit rail of original crowbar is dangerous, time-consuming, effort, inefficient shortcoming, and have the good insulation performance effect, can address the above problem fully.

To achieve these goals, the technical scheme that the utility model adopts is: a kind of railway Insulation crowbar comprises sled head and sled handle; Said sled head takes the shape of the letter U; Its U type plane is vertical with the sled handle, and said sled handle end also connects a fixing iron hammer, the said sled handle straight rod of length that the sled button that removably connects and sled handle tail constitute of serving as reasons; Have blind hole on sled button and the sled handle tail opposing end faces, insert an insulating rod in the blind hole.

As preferably, said sled button is provided with insulation spacer with the joint face of sled handle tail.

As preferably, said insulation spacer is a glass fiber reinforced plastic.

As preferably, said sled button is threaded with sled handle tail.

As preferably, said sled button is pegged graft with sled handle tail each other.

The advantage of the utility model is: simple in structure; Easy to use, insulating properties are reliable, in the railroad maintenance operating process, need not to use the nail nipping pad; Can be widely used on common sleeper circuit and the sleeper track switch; It is respond well to play railway spike, has improved work efficiency, has reached safely, saves time, laborsaving and purpose efficiently.In addition, iron hammer when needed can also the hammering operation.

Fig. 2 is the sectional drawing at A place among Fig. 1.

Among the figure: 1, sled head; 2, sled button; 3, sled handle tail; 4, insulating rod; 5, blind hole; 6, insulation spacer; 7, iron hammer.

The specific embodiment

To combine accompanying drawing and specific embodiment that the utility model is done further explain below.

Referring to Fig. 1, Fig. 2, a kind of railway Insulation crowbar comprises sled 1 and sled handle; Said sled 1 takes the shape of the letter U, and its U type plane is vertical with the sled handle, and said sled handle end also connects a fixing iron hammer 7; Have blind hole 5 on the said sled handle straight rod of length that the sled button that removably connects 2 and sled handle tail 3 constitute of serving as reasons, sled button 2 and sled handle tail 3 opposing end faces, insert insulating rods 4 in the blind hole 5; Said sled button 2 is provided with insulation spacer 6 with the joint face of sled handle tail 3; Said insulation spacer 6 is a glass fiber reinforced plastic, and said sled button 2 is threaded with sled handle tail 3, and said sled button 2 is pegged graft with sled handle tail 3 each other.

The utility model is simple in structure, and is easy to use, and insulating properties are reliable; In the railroad maintenance operating process, need not to use the nail nipping pad, can be widely used on common sleeper circuit and the sleeper track switch, it is respond well to play railway spike; Improved work efficiency, reached safely, save time, laborsaving and purpose efficiently.In addition, iron hammer 7 when needed can also the hammering operation.
