Description

Turnover pedal

Technical Field

The utility model relates to a maintenance of equipment field, especially a upset footboard.

Background

The turnover pedal is mainly applied to platform type structural devices, the turnover pedal has the main function of expanding the working area of a platform, and the turnover connecting points are mostly of hinged structures.

The existing overturning pedal mainly utilizes a hydraulic cylinder or an electric cylinder to push the pedal to rotate around a hinged point in a mode of realizing an overturning function. The defects of the structure are as follows: (1) the structure is complex, and a corresponding hydraulic station or an electric control system is required to be installed to realize the overturning action. The application is difficult in places with compact structure or limited use space; (2) for different application scenes, the rotating strokes of the turning plates are different, the hydraulic cylinder or the electric cylinder needs to be customized, and the manufacturing cost is higher. (3) Generally, the push-pull force of a hydraulic cylinder or an electric cylinder is large, and once stroke deviation occurs in the design or manufacturing process, the overturning pedal is easy to pull and press and deform, so that equipment is damaged.

Therefore, the utility model is especially provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a convenient to use, simple structure, manpower control's upset footboard.

The utility model provides a upset footboard, this upset footboard are used for expanding the platform area, upset footboard (5) pass through articulated elements (6) and articulate in the platform border, make the upset footboard can expand and upwards overturn to the horizontal direction and pack up.

The upper end of the connecting rod (3) is movably connected with a pin shaft horizontally arranged on a platform guardrail upright post, the lower end of the connecting rod is hinged with the upper end of a rocker arm (4), and the lower end of the rocker arm is hinged with the top surface of the turnover pedal;

the upset footboard is when the expansion state, the connecting rod is located same straight line with the rocking arm, and this kind of mode of setting has carried out the restriction to the maximum degree of expansion of upset footboard, can play the effect of drawing to one side when the upset footboard expandes simultaneously, makes the upset footboard more firm, can bear bigger load.

Further, the person skilled in the art can adjust the unfolding degree of the turnover pedal by adjusting the lengths of the connecting rod and the rocker arm.

The pull rod (1) is movably connected with the pin shaft and fixedly connected with the connecting rod, and through the structure, an operator can drive the connecting rod to rotate by taking the pin shaft as a shaft through the pull rod.

Preferably, the pull rod is further provided with a knob plunger (2) for fixing the pull rod and the platform guardrail upright when the pull rod rotates to be parallel to the platform guardrail upright.

Preferably, the lower end of the rocker arm is hinged to the edge, far away from the platform, of the top surface of the turnover pedal. According to the lever principle, the more the hinged position of the rocker arm and the turnover pedal is close to the position, far away from the platform, of the top surface of the pedal, and the more labor is saved when an operator turns the turnover pedal through the pull rod. Therefore, as a preferable scheme, the lower end of the rocker arm is hinged to the edge of the top surface of the turnover pedal, which is far away from the platform.

The turnover pedal provided by the utility model has simple structure, the expansion and the recovery of the turnover pedal can be realized by pulling the pull rod, no extra driving part needs to be configured and installed, and the manufacturing cost is greatly reduced on the premise of realizing the function; the connecting rod has an oblique pulling force on the pedal when the turnover pedal is unfolded, so that the bearing capacity of the pedal is effectively improved; the turnover pedal can be locked by the knob plunger, and the turnover pedal is prevented from swinging back and forth.

Detailed Description

Referring to fig. 1-3, the present invention provides a turnover pedal for expanding the area of a work platform.

The turning pedal 5 is hinged to the edge of the platform through a hinge 6, so that the turning pedal 5 can be unfolded towards the horizontal direction and also can be folded upwards.

The upper end of the connecting rod 3 is movably connected with a pin shaft horizontally arranged on a platform guardrail upright post, the lower end of the connecting rod is hinged with the upper end of a rocker arm 4, and the lower end of the rocker arm 4 is hinged with the top surface of a turnover pedal 5.

As a preferred scheme, when the turnover pedal 5 is in the maximum unfolding state, the connecting rod 3 and the rocker arm 4 are in a straight line, and the design can enable the turnover pedal 5 to be in an inclined pulling effect on the turnover pedal 5 through the connecting rod 3 and the rocker arm 4 when the turnover pedal 5 is unfolded, so that the carrying capacity of the turnover pedal 5 is stronger and more stable. And the angle of the overturning pedal 5 with the horizontal direction when being unfolded can be controlled by adjusting the lengths of the connecting rod 3 and the rocker arm 4 according to actual needs by those skilled in the art.

The pull rod 1 is movably connected with the pin shaft and fixedly connected with the connecting rod 3, so that an operator can drive the connecting rod 3 to rotate together by taking the pin shaft as a shaft through pulling the pull rod 1, and drive the rocker arm 4 to pull the turnover pedal 5 through the connecting rod 3 so as to realize the unfolding and folding of the turnover pedal 5.

Furthermore, in order to fix the turnover pedal 5 in a folded state, a knob plunger 2 is further arranged on the pull rod 1, and the pull rod 1 is just rotated to a position parallel to the guardrail upright of the platform when the turnover pedal 5 is folded by adjusting an included angle between the pull rod 1 and the connecting rod 3. A threaded hole is constructed in the corresponding position of the platform guardrail upright post, and is used for an operator to screw the knob plunger 2 into the threaded hole so as to fix the pull rod 1 and the platform guardrail upright post, thereby locking the turnover pedal 5 in a retracted state.

Furthermore, in order to save more labor when the operator pulls the pull rod 1, the lower end of the rocker arm 4 is hinged to the edge of the top surface of the turnover pedal 5 far away from the platform by the lever principle.

When the turnover pedal provided by the utility model is used, an operator firstly contacts the locking state of the pull rod and the platform guardrail upright post by rotating the knob plunger, and drives the connecting rod and the rocker arm to unfold the turnover pedal by pulling the pull rod; after the turnover pedal is used, the turnover pedal is folded by pulling the pull rod, and the pull rod and the platform guardrail upright post are fixed by rotating the knob plunger, so that the turnover pedal is locked.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, and simple improvements made in the spirit of the present invention should be included in the protection scope of the present invention.
