Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a weighing fork. Background Art

[0002] In order to improve the turnover efficiency of goods during loading, unloading and turnover, it is usually necessary to equip the forklift with a forklift scale so that handling and weighing can be carried out simultaneously.

[0003] The existing forklift scale is located between the forklift's bracket and the fork. The fixed part of the forklift scale is connected to the front side of the forklift's bracket, and the floating part of the forklift scale is connected to the rear side of the vertical fork body of the fork. The forklift scale senses the weight of the cargo lifted by the fork.

[0004] However, configuring a forklift scale separately on the fork not only increases the load capacity of the fork, but also increases the distance between the front surface of the vertical fork body of the fork and the hanger, thereby increasing the overturning moment of the entire forklift and reducing the stability of the forklift. Utility Model Content

[0008] The height of the moving gap is not greater than the deformation amount corresponding to the maximum measuring range of the weighing sensor.

[0009] An auxiliary groove is provided on one side of the fixed scale plate facing the installation groove, and the weighing sensor is located in the middle of the chamber formed by the auxiliary groove and the installation groove. The design of the auxiliary groove can reduce the counterweight of the fixed scale plate and minimize the increase of the overturning moment on the basis of ensuring the installation space of the weighing sensor.

[0010] The first connecting plate and the second connecting plate are provided with through holes corresponding to each other, and threaded portions are formed at both ends of the vertical pull rod.

[0021] In order to enable those skilled in the art to better understand the technical solution in the utility model, the technical solution in the utility model is clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by those skilled in the art without making any creative work should all fall within the protection scope of the utility model.

[0022] like Figure 3-Figure 5 As shown, the utility model provides a weighing fork, including a fork 1, a fixed scale plate 4 and a weighing sensor 5. A mounting groove 105 is provided at the rear side of the vertical fork body 101 of the fork 1. The fixed scale plate 4 is mounted on the mounting groove 105 via a guide assembly. A first connecting plate 7 is fixed on the inner wall of the mounting groove 105. A second connecting plate 8 is fixed on the side of the fixed scale plate 4 facing the mounting groove 105. Both ends of the weighing sensor 5 are connected to the first connecting plate 7 and the second connecting plate 8 via a vertical pull rod 6. In this embodiment, the first connecting plate 7 is located at the bottom, and the second connecting plate 8 is located at the top. Both the first connecting plate 7 and the second connecting plate 8 are arranged horizontally. The force of the first connecting plate 7 acts on the lower end of the weighing sensor 5 through the vertical pull rod 6, and the reaction force of the second connecting plate 8 acts on the upper end of the weighing sensor 5 through the vertical pull rod 6.

[0023] By opening a mounting groove 105 in the vertical fork body 101 of the fork 1, the weighing sensor 5 is integrated in the fork 1. Compared with the prior art, the distance between the front surface of the vertical fork body 101 and the hanger 3 is shortened. At the same time, the mounting groove 105 can reduce the weight of the entire fork 1 to the greatest extent, thereby ensuring the stability of the forklift installed with the fork 1; and the two ends of the weighing sensor 5 are vertically connected to the first connecting plate 7 on the fork 1 and the second connecting plate 8 on the fixed scale plate 4 through the vertical pull rod 6, which can ensure the stability of the weighing sensor 5 receiving the vertical tension from the fork 1.

[0024] In order to prevent the fork 1 from tilting forward relative to the fixed scale plate 4 and ensure the vertical stability of the fork 4 during weighing, Figure 6As shown, the guide assembly includes a guide portion 403 extending outward from both ends of the fixed scale plate 4, and guide grooves 106 corresponding to the guide portion 403 are provided on the fork 1 at both ends of the notch of the mounting groove 105. Specifically, the groove wall of the guide groove 106 away from the side of the fork 1 abuts against the outer wall of the guide portion 403, so as to block the forward tilt of the fork 1 in the horizontal direction. A moving gap 11 is provided between the groove bottom of the guide groove 106 and the end of the guide portion 403, so as to meet the vertical relative movement between the fork 1 and the fixed scale plate 4 during weighing. Preferably, the height of the moving gap 11 is not greater than the deformation corresponding to the maximum range of the weighing sensor 5, so as to avoid the weighing sensor 5 from being damaged due to over-range. The weighing sensor 5 in this embodiment is an S-type weighing sensor, and its rated range is selected according to the demand.

[0025] like Figure 3 As shown, in order to facilitate the snap-fit ​​installation of the fixed scale plate 4 and the installation groove 105, the upper end of the installation groove 105 is open, and a cover plate 12 is provided at the upper end opening of the installation groove 105. The cover plate 12 is detachably installed on the fork 1 by bolts, and the guide groove 106 is opened at a position where the cover plate 12 is away from the installation groove 105.

[0026] like Figure 5 As shown, an auxiliary groove 404 is provided on one side of the fixed scale plate 4 facing the installation groove 105, and the weighing sensor 5 is located in the middle of the chamber formed by the auxiliary groove 404 and the installation groove 105. The design of the auxiliary groove 404 can reduce the counterweight of the fixed scale plate 4, and on the basis of ensuring the installation space of the weighing sensor 5, the overturning moment can be minimized.

[0027] The first connecting plate 7 and the second connecting plate 8 are provided with through holes corresponding to each other, and the two ends of the vertical tie rod 6 are formed with threaded parts, one end of the vertical tie rod 6 is threadedly connected to the threaded hole on the surface of the weighing sensor 5, and the other end of the vertical tie rod 6 passes through the through hole, and the threaded parts on both sides of the through hole are threadedly connected with adjusting nuts 9. In order to further ensure the stability of the weighing sensor 5 and the vertical tie rod 6, a locking nut 10 is installed at the connection between the vertical tie rod 6 and the weighing sensor 5, and the locking nut 10 is in locking contact with the end face of the weighing sensor 5.

[0028] The fixed scale plate 4 is provided with a hook assembly on the side facing away from the installation slot 105, and the hook assembly includes hanging plates 401 fixed to both ends of the fixed scale plate 4, and the inner sides of the two hanging plates 401 are provided with hook parts 402 that cooperate with both ends of the forklift hanger 3. By hanging the upper and lower hanging plates on the upper beam and the lower beam of the forklift hanger 3 respectively, the stable installation of the entire fork 1 structure can be achieved.

[0029] In order to reduce the space occupied by the fork 1, the fork 1 in this embodiment is a foldable fork 1, and the lower end of the vertical fork body 101 of the fork 1 and the end of the horizontal fork body 102 away from the fork tip are rotatably connected through a pin 103. Specifically, a connecting ear 104 is formed on the lower end of the vertical fork body 101 of the fork 1 and the end of the horizontal fork body 102 away from the fork tip, and the pin 103 sequentially passes through the axial hole on the connecting ear 104 to complete the rotational connection between the vertical fork body 101 and the horizontal fork body 102 of the fork 1; in other embodiments, the fork 1 can also be an integrated fork 1.

[0030] When implementing the present technical solution, the staff will place the weighing sensor 5 equipped with the vertical pull rod 6 in the mounting groove 105, and fix it to the first connecting plate 7 of the mounting groove 105 by adjusting the nut 9, and the fixed scale plate 4 will be buckled in the notch of the mounting groove 105, and enter through the upper end opening of the mounting groove 105 to fix the second connecting plate 8 and the vertical pull rod 6. The cover plate 12 will be fixed at the upper end opening of the mounting groove 105 to complete the assembly of the entire fork 1 structure, and the assembled fork 1 will be hung on the fork frame of the forklift through the hanging plate. When the forklift is performing handling and weighing operations, the overturning moment of the forklift is not substantially increased, thereby ensuring the stability of the forklift.
