Description

Technical Field

[0001] This utility model relates to the field of forklift equipment technology, specifically a forklift front fork load collection device. Background Technology

[0002] In logistics warehousing, industrial material handling, and other fields, forklifts are core loading and unloading equipment, and the real-time collection and monitoring of their fork load data is crucial for ensuring operational safety and optimizing load management. Traditional forklift fork load monitoring methods mostly rely on external weighing equipment or simple sensors, which have the following prominent problems:

[0003] 1. Some load collection devices require drilling holes, welding, or fixing through complex structures on the forks, which not only damages the original structural strength of the forks, but also makes it difficult to adapt to forks of different thicknesses and specifications, resulting in low versatility.

[0004] 2. An unreasonable sensor layout (such as single-point acquisition or non-uniform distribution) can easily lead to large errors in load data due to the shift of the center of gravity of the goods, making it impossible to accurately reflect the actual load status.

[0005] 3. The fixing components are prone to loosening due to vibration or impact of goods, which may lead to poor contact between the sensor and the fork, affecting the continuity of data.

[0006] Therefore, developing a forklift fork load data acquisition device that is easy to install, highly adaptable, has high data acquisition accuracy, and operates stably has become a technical requirement that the industry urgently needs to address. Utility Model Content

[0007] To address the aforementioned problems, this utility model provides a forklift front fork load collection device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a forklift front fork load collection device, comprising a load collection mechanism disposed on the forklift body, the load collection mechanism comprising a mounting rod disposed on the top side of the fork, a load collection component disposed on the mounting rod, two fixed rods symmetrically disposed on both sides of the mounting rod, and a fixed component disposed on each fixed rod and abutting against the bottom side of the fork.

[0009] Preferably, each of the two fixed rods in each group has a fixed hole at its bottom. The fixing assembly includes a positioning bolt passing through the two corresponding fixed holes, two first positioning blocks located between the two fixed rods in each group and respectively threaded onto both ends of the symmetrical positioning bolt rod, and a second positioning block located between the two first positioning blocks. The threads on both ends of the positioning bolt rod are in opposite directions.

[0010] Preferably, the two first positioning blocks have opposite sides that are inclined, and the distance between the two first positioning blocks with opposite inclined surfaces gradually increases from bottom to top; the symmetrical sides of the second positioning block are all inclined structures that match the opposite inclined surfaces of the first positioning blocks, and the bottom end of the second positioning block has an opening that fits onto the positioning bolt rod.

[0011] Preferably, the end of the positioning bolt is connected to a positioning nut via a thread.

[0012] Preferably, the load acquisition component includes multiple pressure sensors disposed in a connecting groove on the top side of the mounting rod, a connecting rod that slides through the connecting groove and whose bottom side contacts the acquisition ends of the multiple pressure sensors, and a support rod disposed parallel to the top of the mounting rod and connected to the connecting rod. The multiple pressure sensors are arranged at equal intervals along the length direction of the connecting groove opening.

[0013] The beneficial effects of this utility model are:

[0014] 1. The fixing component adopts a "positioning bolt + bidirectional inclined positioning block" structure. The positioning bolts with opposite thread directions drive the first positioning blocks on both sides to move synchronously in opposite directions. Combined with the inclined surface of the second positioning block, it can quickly clamp the bottom side of forks of different thicknesses without the need to drill holes or modify the forks. It is compatible with various standard / non-standard forks and greatly reduces the installation threshold.

[0015] 2. In the load acquisition component, multiple pressure sensors are arranged at equal intervals along the length of the top side of the fork. The pressure of the cargo is evenly transmitted to each sensor through the support rod-connecting rod structure, avoiding local overload or data distortion caused by the shift of the center of gravity of the cargo, reducing the load acquisition error and meeting the requirements of high-precision monitoring.

[0016] 3. The fixing components can be clamped or loosened by simply rotating the positioning bolts, making it easy for a single person to install and disassemble without the need for professional tools; the sensor is integrated into the connecting groove of the mounting rod, and replacement only requires disassembling the support rod and connecting rod, reducing maintenance costs.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0024] Example 1: Reference Figures 1-4 The forklift front fork load collection device shown includes a load collection mechanism installed on the forklift body 1 fork 2. The load collection mechanism includes a mounting rod 3 installed on the top side of the fork 2, a load collection component installed on the mounting rod 3, two sets of fixing rods 5 symmetrically arranged on both sides of the mounting rod 3, and a fixing component installed on each set of fixing rods 5 and abutting against the bottom side of the fork 2.

[0025] In this embodiment, during installation, the mounting rod 3 is placed on the top side of the fork 2, and the position is adjusted so that the fixing rods 5 on both sides of the fork are symmetrically distributed. The positioning bolts 12 at the bottom of each set of fixing rods 5 are rotated. Since the threads at both ends of the positioning bolts 12 are opposite, rotation drives the first positioning blocks 7 on both sides to move synchronously towards the center. The inclined surface of the first positioning block 7 contacts the inclined surface of the second positioning block 8, pushing the second positioning block 8 upwards. Finally, the top side of the second positioning block 8 presses against the bottom side of the fork 2, forming a three-way clamping force of "up-down-inclined surface," firmly fixing the mounting rod 3 to the fork. Finally, the positioning bolts 12 are tightened with positioning nuts to prevent loosening. When the forklift body 1 is working, the cargo is placed on the top side of the fork 2. The weight of the cargo is evenly transferred to the load acquisition component through the support rod 4, the weight of the cargo is collected, and the collected electrical signal is transmitted to the forklift control system (or an external display device). The control system processes signals through algorithms (such as mean calculation and center of gravity correction) and outputs real-time load data (such as "current load: 2000kg") and overload warnings.

[0026] In this embodiment, the fixing component uses a "positioning bolt + bidirectional inclined positioning block" structure to clamp forks 2 of different models, sizes and thicknesses without requiring drilling or modification of the forks 2. It is compatible with various standard / non-standard forks (such as square tube forks and I-beam forks), reducing the installation threshold.

[0027] It is understood that the mounting rod 3 can be mounted on the fork 2 in various ways. This embodiment provides the following solution:

[0028] like Figures 1-4 As shown, each of the two fixed rods 5 in each group has a fixing hole at its bottom. The fixing assembly includes a positioning bolt 12 that passes through the two corresponding fixing holes, two first positioning blocks 7 that are set between the two fixed rods 5 in each group and respectively threadedly connected to the two ends of the symmetrical positioning bolt 12, and a second positioning block 8 located between the two first positioning blocks 7. The threads on the two ends of the positioning bolt 12 are in opposite directions.

[0029] The end of the positioning bolt 12 is connected to a positioning nut via a thread.

[0030] In this embodiment, when installing the mounting rod 3 onto the fork 2, the mounting rod 3 is first placed on the top side of the fork 2. At this time, each group of two fixed rods 5, which are symmetrically arranged on the bottom side of the mounting rod 3, are symmetrical about the fork 2. Then, the positioning bolt 12 is rotated, which causes the two first positioning blocks 7 located at both ends of the positioning bolt 12 to move closer to each other. At this time, the two first positioning blocks 7 push the second positioning block 8 located between the two first positioning blocks 7 to move upward, so that the top of the second positioning block 8 abuts against the bottom side of the fork 2. This makes it easy to install the mounting rod 3 stably and conveniently onto the fork 2, and connects it with the positioning nut at the end of the positioning bolt 12, thus preventing the positioning bolt 12 from becoming loose.

[0031] like Figure 3 and Figure 4 As shown, the two first positioning blocks 7 have opposite sides that are inclined, and the distance between the two first positioning blocks 7 relative inclined surfaces gradually increases from bottom to top; the symmetrical sides of the second positioning block 8 are all inclined structures that match the opposite inclined surfaces of the first positioning blocks 7, and the bottom end of the second positioning block 8 has an opening 11 that is fitted onto the rod of the positioning bolt 12.

[0032] In this embodiment, the two first positioning blocks 7 located between the two fixed rods 5 in each group have inclined sides. When the control positioning bolt 12 is rotated, the two first positioning blocks 7 can be driven to move closer to each other. At this time, under the action of the inclined sides of the two first positioning blocks 7 pushing the inclined sides of the symmetrical side of the second positioning block 8, the top of the second positioning block 8 is driven to tightly abut against the bottom side of the fork 2, so that the mounting rod 3 can be stably installed on the fork 2.

[0033] Example 2: Regarding the load acquisition component in Example 1 above, this example provides the following solution.

[0034] like Figure 3 As shown, the load acquisition component includes multiple pressure sensors 10 disposed in the connecting groove 9 on the top side of the mounting rod 3, a connecting rod 6 that slides through the connecting groove 9 and whose bottom side contacts the acquisition end of the multiple pressure sensors 10, and a support rod 4 that is parallel to the mounting rod 3 and connected to the connecting rod 6. The multiple pressure sensors 10 are arranged at equal intervals along the length direction of the opening of the connecting groove 9.

[0035] In this embodiment, multiple pressure sensors 10 are arranged at equal intervals along the length of the top side of the fork 2. Through the rigid transmission of the connecting rod 6, it is ensured that each sensor can still evenly share the pressure when the center of gravity of the cargo shifts, avoiding the acquisition error caused by local overload, avoiding local overload or data distortion caused by the shift of the center of gravity of the cargo, reducing the load acquisition error, and meeting the high-precision monitoring requirements.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
