A forklift auxiliary balancing device

Abstract

This utility model discloses an auxiliary balancing device for forklifts, relating to the technical field of auxiliary balancing devices. It includes a connecting seat with two sets of forks on its front surface. The forks drive a baffle to contact one end of the cargo. The restoring force of a torsion spring causes a rotating rod to rotate and reset within a groove, at which point a limiting plate is placed horizontally within the groove. The operator then manually rotates the limiting plate out of the groove, placing it vertically. An electric push rod then moves the forks via a support plate, simultaneously causing a sliding plate to slide within a groove until the baffle and limiting plate are in contact with the front and rear ends of the cargo, thus achieving the purpose of limiting the cargo's position. This prevents the cargo from easily shifting forward or backward on the forks due to inertia caused by road bumps, acceleration / deceleration, or turning, which could lead to the forklift tilting or tipping over. This improves the balance of the forks when handling cargo.

Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary balancing devices, specifically an auxiliary balancing device for forklifts. Background Technology

[0002] In modern industrial production and logistics, forklifts, as highly efficient material handling equipment, are widely used in warehouses, ports, factories, and other settings, undertaking important tasks such as loading, unloading, stacking, and short-distance transportation of goods. With the continuous expansion of industrial production scale and the rapid development of the logistics industry, increasingly higher requirements are being placed on the operating efficiency, load-bearing capacity, and operational safety of forklifts.

[0003] According to a patent application published on the internet (publication number CN221217051U), a forklift includes a vehicle body. A mast structure is connected to the front of the vehicle body, a single scissor lift structure is connected to the front of the mast structure, and a fork structure is connected to the front of the single scissor lift structure. The single scissor lift structure is used to drive the fork structure to move forward or backward. An angle conversion device and load wheels are provided on the legs of the vehicle body.

[0004] To address the issues of reach trucks' large size, excessive turning radius, and large operating space, which prevent them from turning in confined workspaces and reduce forklift and space utilization, the existing single-scissor structure in this application allows the forks to be kept away from the forklift legs, preventing collisions with rack columns or other objects during cargo handling. The angle conversion device allows the load wheel to be switched at any angle in coordination with the drive wheel's rotation direction, enabling free entry and exit in narrow workspaces, reducing safety risks, and improving overall forklift and warehouse space utilization. However, during operation, the inertia of cargo due to road bumps, acceleration, deceleration, or turning can easily cause the cargo to shift forward or backward on the forks. This displacement can lead to a significant shift in the cargo's center of gravity, potentially causing the forklift to tilt or tip over. Therefore, improvements are urgently needed.

[0011] As a further preferred embodiment of this technical solution, an anti-loosening washer is provided between the handwheel and the fork, and the handwheel is rotatably connected to the fork through the anti-loosening washer.

[0012] This utility model provides an auxiliary balancing device for forklifts, which has the following beneficial effects:

[0013] 1. This utility model uses the forks to drive the baffle to fit against one end of the cargo. The restoring force of the torsion spring drives the rotating rod to reset and rotate within the rotating groove. At this time, the limiting plate is placed horizontally within the rotating groove. Then, the operator manually rotates the limiting plate out of the rotating groove, making the limiting plate vertical. Then, the electric push rod drives the forks to move through the support plate, and simultaneously drives the sliding plate to slide within the sliding groove until the baffle and the limiting plate fit against the front and rear ends of the cargo, thereby achieving the purpose of limiting the cargo and preventing the cargo from easily moving forward or backward on the forks due to the inertia generated by road bumps, acceleration, deceleration, or turning, which could cause the forklift to tilt or tip over. This improves the balance of the forks when handling cargo.

[0014] 2. This utility model uses two sets of handwheels to drive the lead screw to rotate in the guide groove, and the lead screw acts synchronously on the transmission block, which in turn moves the transmission block in the guide groove.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an auxiliary balancing device for a forklift includes a connecting seat 1. Two sets of forks 2 are provided on the front surface of the connecting seat 1. A clamping component 3 for front and rear limiting of goods is provided at the front end of the forks 2. A limiting component 4 for lateral limiting of goods on the forks 2 is provided inside the forks 2.

[0022] like Figure 1 and Figure 4 As shown, the clamping assembly 3 includes an electric push rod 31 fixedly connected to the front surface of two sets of forks 2. A support plate 32 is fixedly connected to the front end of the electric push rod 31. Two sets of sliding plates 33 are fixedly connected to the side of the support plate 32 facing the forks 2. The forks 2 are provided with sliding grooves 34 corresponding to the sliding plates 33. A baffle 35 is fixedly connected to the surface of the forks 2 behind the sliding grooves 34. A rotating groove 36 is provided at the top of the support plate 32. A rotating rod 37 is rotatably connected in the rotating groove 36. Torsion springs 38 are provided on the two ends of the rotating rod 37 in the rotating groove 36. A limit plate 39 is fixedly connected to the outer surface of the rotating rod 37.

[0023] The forks 2 drive the baffle 35 to fit against one end of the cargo. Then, the torsion spring 38 uses its restoring force to drive the rotating rod 37 to rotate and reset within the rotating groove 36. At this time, the limiting plate 39 is placed horizontally within the rotating groove 36. Afterward, the operator manually rotates the limiting plate 39 out of the rotating groove 36, making the limiting plate 39 vertical. Then, the electric push rod 31 drives the forks 2 to move through the support plate 32 until the baffle 35 and the limiting plate 39 fit against the front and rear ends of the cargo, respectively. This achieves the purpose of limiting the cargo by ensuring that the cargo does not easily move forward or backward on the forks 2 due to the inertia caused by road bumps, acceleration, deceleration, or turning, which could lead to the forklift tilting or tipping over. This improves the balance of the forks 2 when handling cargo.

[0024] like Figure 1 and Figure 4 As shown, the outer wall of the corresponding end of the baffle 35 and the limiting plate 39 is provided with a soft pad, and the soft pad is an anti-slip soft pad, which can reduce the hard contact between the goods and the baffle 35 and the limiting plate 39, and prevent the goods from rubbing against the baffle 35 or the limiting plate 39 continuously when the forklift is handling the goods and causing bumps, which would result in damage to the surface of the goods.

[0025] like Figure 1 and Figure 4 As shown, the top surface of the slide plate 33 is flush with the top surface of the fork 2. The slide groove 34 is formed by a through hole that matches the shape of the slide plate 33, which enables the slide plate 33 to support the goods. At the same time, the slide groove 34 can also guide the slide plate 33, so that the slide plate 33 can move back and forth stably on the fork 2.

[0026] like Figure 1 and Figure 3 As shown, the limiting component 4 includes a guide groove 41 formed on the front surface of the fork 2. A lead screw 42 is rotatably connected in the guide groove 41. A handwheel 43 is fixedly connected to the side of the lead screw 42. The handwheel 43 is rotatably connected to the fork 2. A transmission block 44 is threadedly connected to the lead screw 42. A side plate 46 is fixedly connected to the outer wall of the transmission block 44.

[0027] Two sets of handwheels 43 drive the lead screw 42 to rotate in the guide groove 41, and the lead screw 42 acts synchronously on the transmission block 44, which moves the transmission block 44 in the guide groove 41. The transmission block 44 synchronously drives the connecting block 45 to move, and the two sets of side plates 46 cover the sides of the goods to prevent the goods from slipping or tilting on the forks 2, which could lead to the forklift tipping over.

[0028] like Figure 1 and Figure 3As shown, an anti-loosening washer is provided between the handwheel 43 and the fork 2. The handwheel 43 is rotatably connected to the fork 2 through the anti-loosening washer. The tension between the two anti-loosening washers can be used to brake and prevent the handwheel 43 from loosening, thereby improving the stability of the handwheel 43 driving the lead screw 42 to rotate in the guide groove 41.

[0029] This utility model provides an auxiliary balancing device for forklifts. The specific working principle is as follows: First, the rotating rod 37 rotates in the rotating groove 36, causing the limiting plate 39 to rotate into the rotating groove 36. At the same time, the rotating rod 37 continuously twists the two sets of torsion springs 38. Then, the forklift drives the forks 2 to slide into the bottom of the goods, making the goods fit against the baffle 35. When there is no goods on the limiting plate 39, the restoring force of the torsion spring 38 drives the rotating rod 37 to reset and rotate in the rotating groove 36, causing the limiting plate 39 to rotate out of the rotating groove 36. The outer wall of the limiting plate 39 fits against the inner wall of the rotating groove 36. Then, the electric push rod 31 drives the forks 2 to move through the support plate 32, and simultaneously drives the slide plate 33 to slide back and forth in the sliding groove 34, thereby achieving the purpose of limiting the goods by making the baffle 35 and the rotating groove 36 fit against the front and rear ends of the goods.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
