Description
Technical Field
The utility model relates to an electric power generating line makes technical field, specifically is an improve life and convenient tensile dolly of maintaining.
Background
The electric bus generally adopts aluminum pipes or aluminum alloy pipes, a large amount of aluminum or aluminum alloy pipes need to be produced in the manufacturing process, the pipes need to be stretched in the production process at present, one end of each pipe is clamped by a clamp during stretching, and the pipe is stretched backwards to enable the inner hole and the outer diameter of each pipe to meet the design requirements.
Disclosure of Invention
The utility model aims at providing a improve life and convenient tensile dolly of maintaining in order to solve current tensile dolly unhook device life low, maintain and change inconvenient problem.
The utility model has the following concrete scheme: the utility model provides an improve life and convenient tensile dolly of maintaining, includes the automobile body, and the automobile body top is equipped with the platform, and the clamp is equipped with to the platform front end, and the clamp is used for pressing from both sides to get the pipe fitting of treating stretching, unhook mechanism is equipped with to the platform rear end, unhook mechanism is including the fixing support who is fixed in the automobile body top, and fixing support includes two vertical extension boards, and a horizontally pivot A is equipped with to two extension board upper ends, and pivot A one end extends and fixes being equipped with a lance to the automobile body outside, lies in to fix being equipped with a cam between two extension boards in pivot A, and the pivot B is equipped with in the rear lower place that lies in pivot A between two extension boards, is equipped with a swing arm on the pivot B, swing arm front end top surface with.
The lance is parallel to the symmetrical center line of the cam.
Clamp includes the vertical scroll, is equipped with two connecting rods on the vertical scroll, and the front end of two connecting rods respectively articulates there is a pincers body, is equipped with the articulated shaft in the middle of two pincers bodies, and two pincers body front ends form the jaw portion, be equipped with reset spring between articulated shaft and the vertical scroll.
The working principle of the utility model is as follows: before stretching, the jaw part of the clamp is in an opening state, when the vehicle body moves forwards to the head part of the pipe blank, the striker is collided, the striker drives the cam to rotate upwards by taking the rotating shaft A as an axis, one end of the hook of the suspension rod automatically descends due to the dead weight and the lever action, the hook hooks the stretching chain, meanwhile, the clamp clamps the pipe fitting, the stretching chain pulls the whole trolley backwards to realize the stretching action of the pipe fitting, in the stretching process, the hook overcomes the dead weight and the lever action force exerted by the cam due to the pulling force of two ends, when the pipe fitting is stretched, the stress of the hook is unbalanced, the action force of the cam on the suspension rod is dominant.
The utility model discloses following beneficial effect has: the unhooking mechanism has a simple structure, fewer force transmission parts, convenience in maintenance and replacement of parts and prolonged service life.
