Abstract
The utility model discloses a handheld impact tamping pickaxe which mainly consists of a body, a pickaxe borer arranged below the body and two handrails arranged on the upper part of the body; the handlebars of the two handrails are arranged in parallel with a direction pointed to an operator. The handrails of the handheld impact tamping pickaxe disclosed in the utility model adopts a 'parallel' design structure according to the operating environments of railway engineering and human engineering principle, which has a reasonable structure; when the handheld impact tamping pickaxe is used for implementing tamping operation, an operator can operate by only needing to naturally grasp the handlebars by the two hands and arranging the pickaxe borer in ballasts and not needing to apply excessive external forces on the tamping pickaxe. The handheld impact tamping pickaxe has the characteristics of simple structure, light weight and uneasy fatigue of operators, etc.
Description
Technical field
The utility model relates to the tamping pickaxe that the railway maintenance is used, and more specifically says, relates to a kind of portable impact tamping pickaxe.
Background technology
Portable impact tamping pickaxe is the important tool that the railway maintenance is used, and mainly is made of body, pick rod and handrail, and pick rod is placed in the body below, and handrail is the lever of " one " font, is installed with in the body upper both sides.When carrying out tamping operation, hold " one " font handrail to the intort both arms, the pick rod of tamping pickaxe is inserted the oscillating movement that does not stop in the ballast aggregate of railway roadbed, realize the railway roadbed tamping, make railway remain on safe operation requirement level by the operator with it.Use the impact tamping pickaxe to carry out tamping operation, the operator holds " one " font handrail to the intort both arms, and operator's mode of operation is nature not, the operation effort, long period of operation is tired easily, and the impact shock of tamping pickaxe can produce the vibratory impulse influence to the operator by handrail.Find after deliberation, this portable impact tamping pickaxes of present a large amount of uses in the railroad ballast tamping operation, by the definite mode of operation of its armrest, easily make operator's fatigue, and the operator is in the fatigue state operation, can obviously reduce operating efficiency, even accidents caused and occupational disease, so the portable impact tamping pickaxe structure of prior art is badly in need of improving.
Summary of the invention
At the deficiency that the portable impact tamping pickaxe of prior art exists, the purpose of this utility model provides nature of a kind of operator's mode of operation, the portable impact tamping pickaxe of the tireless new structure of rapid operation.
Above-mentioned purpose of the present utility model can be accomplished by the portable impact tamping pickaxe of following technical proposals.
The disclosed portable impact tamping pickaxe of the utility model mainly is made of body, two handrails that are placed in the pick rod of body below and are placed in body upper, and the handgrip of two handrails (grasp part) is for be arrangeding direction point operation person in parallel.The direction of the handgrip of handrail and operator front be 75 °～90 ° all can, preferably be 90 ° approximately.
In the technical scheme of above-mentioned portable impact tamping pickaxe, preferably the handgrip distance with two handrails is designed to suitable with the shoulder breadth of being grown up; Further scheme is designed to exceed the body top with the handgrip of handrail, and when making the operator with its operation, the handgrip height of handrail is bent upwards altitude range after 60 °～90 ° at the forearm of being grown up.
In the technical scheme of above-mentioned portable impact tamping pickaxe, the shape of two handrails can there be multiple structure, as the curved structure bar or the bending structure bar of crouch " L " font or " 7 " font that crouches, can preferentially can consider the bending structure bar that adopts " 7 " font that crouches.Two handrails can be arranged on end face, front, back or the two sides of body, preferentially can consider two handrails are fixedly arranged in the body two sides respectively.Two handrail integral body from the front see be below incomplete " V " font.Can cover to put at the handgrip of two handrails and hold the good non-metallic material layer of sense, or be nested with and hold the good non-metallic material cover of sense, can pay the utmost attention to a kind of form in back that adopts.The pick palm protrusion direction of pick rod is preferably identical with operator's frontal.
The disclosed portable impact tamping pickaxe of the utility model, the handle structure of two handrails is according to railway operating environment and ergonomics principle, take " parallel " design of point operation person, reasonable in design, when carrying out tamping operation with it, the operator only needs the flat naturally handle of shaking hands of both hands, place ballast aggregate can carry out operation pick rod, and do not need the operator that tamping pickaxe is applied too much external force, make operation comfortable more naturally, solve the portable impact tamping pickaxe of prior art handrail " " font structure fully and design existing problem, changed operator's mode of operation, the impact shock that the muscle power that has reduced the operator is paid with tamping pickaxe produces vibratory impulse influence, long period of operation indefatigability to the operator, improve operating efficiency, thereby reduced the generation of accident and occupational disease.
The disclosed portable impact tamping pickaxe of the utility model is compared with the portable impact tamping pickaxe of prior art, the advantage that it had, and concentrated summary gets up to be simple in structure, in light weight, operating personnel's indefatigability, efficiency height.
