The technical solution described in the present invention will be described clearly and completely with reference to the accompanying drawings and specific embodiments, and obviously, the embodiments described in the present specification are only a part of the feasible technical solutions of the present invention, and other embodiments obtained without any creative work by a person of ordinary skill in the art based on the embodiments of the present invention should be considered as belonging to the protection scope of the present invention.
It should be noted that the descriptions of "first", "second", etc. used in the embodiments of the present invention are only for descriptive purposes, and should not be interpreted as indicating or implying any limitation to the number of technical features, and therefore, the features defined as "first", "second", etc. in the embodiments of the present invention may mean that at least one of the defined technical features is included. The term "connected" defined in the embodiments of the present disclosure defines a functional relationship between two structures, and thus, the term "connected" used in the embodiments of the present disclosure includes a contact connection, a non-contact connection, a direct connection, an indirect connection, and the like.
The utility model discloses a fork weighing module mainly used realizes with the fork cooperation that the fork directly weighs to the while of freight, and is concrete, can install and realize weighing with the fork cooperation on the fork truck scale structure, also can the direct mount on fork body 10, and is preferred, installs inside the vertical yoke 20 of fork body 10. The vertical fork arm and the horizontal fork arm cited in the embodiment of the specification limit the vertical and horizontal according to the common state of the fork in use, and the vertical fork arm 20 of the common L-shaped fork is mainly used for fixedly connecting with a fork truck frame and installing the fork at the front end of the fork truck; the horizontal fork arms 30 are used to fork the cargo and lift the cargo off the ground to a desired location. Therefore, in the working process of the fork, the fork body 10 can bear the load due to the load, and at the moment, the load pressure applied to the fork measured by the weighing module is the weight of the load borne by the fork.
The utility model discloses a fork weighing module is the suspension type weighing component of installing inside vertical yoke 20 of fork body 10, and is concrete, refer to figure 1 and figure 2, the utility model discloses a fork weighing module includes that weighing sensor 1, inner arm 2 and lock are in the outside enclosing cover 3 of inner arm 2, 1 both ends of weighing sensor butt respectively the inner arm 2 with enclosing cover 3 for produce a vertical decurrent pressure with weighing sensor 1's one end butt department after inner arm 2 receives the pressure of goods, simultaneously, enclosing cover 3 produces a vertical ascending holding power that the direction is opposite that the size equals with the butt department of the weighing sensor 1 other end, and at this moment, the power that weighing sensor 1 recorded is the gravity of the goods that bears on the fork promptly. In order to ensure that the cargo pressure applied to the inner arm 2 is completely converted into the acting force of the weighing sensor 1, it is necessary to ensure that no additional acting force is generated in the vertical direction when the inner arm 2 and the outer cover 3 are displaced relatively, i.e. no friction connection is generated between the inner arm 2 and the outer cover 3, so that no friction force is generated when the two move relatively. For realizing above-mentioned technological effect, the inner arm 2 with connect through ball assembly 4 between the enclosing cover 3, when stacking the goods bearing on the fork, the fork inner arm 2 takes place the displacement through ball assembly 4 relative enclosing cover 3 downwards, turns into the pressure of weighing sensor 1 completely through the goods gravity that will receive. Because the inner arm 2 and the outer cover 3 can not be contacted to form a sealed inner space, a gap is formed between the side surface of the inner arm 2 and the outer cover 3, impurities can enter the ball assembly 4 through the gap, the balls can be damaged by accumulating the impurities for a long time, and the inner arm 2 and the outer cover 3 generate friction when moving mutually to reduce the gravity of goods, so that weighing errors are caused.
