Description

Technical Field

[0001] This invention relates to a lifting device, and more particularly to a chain forklift. Background Technology

[0002] In the metal strip post-processing production line, the defective parts of the strip need to be cut before winding. The cut waste needs to be collected and processed. Generally, a waste collection box is set up after the roll shearing machine conveyor line. The cut waste segments fall into the waste collection box through the conveyor line. After the waste collection box is full, it is transported outside the work area for packaging. During the waste collection process, the impact of the waste falling into the waste collection box can easily generate noise. The on-site environment is relatively noisy, and the harsh noise of the impact can have a certain impact on the on-site operators. If the waste collection box is set too high, it is inconvenient to operate during packaging. Considering the current on-site conditions of the strip processing production line, a lifting device needs to be developed and designed. When the waste is cut on the production line, the waste collection box is raised to its highest point to reduce the height of the waste falling and reduce the noise generated by the falling impact. The height of the waste collection box can be adjusted according to the degree of waste collected. After the waste collection box is full, it is lowered to its lowest point and placed on a transfer vehicle for transport outside the work area for packaging. Summary of the Invention

[0030] This utility model specifically relates to a chain lifting machine, which is applied to surface treatment production lines for metal plates and strips such as tin plating, chromium plating, and degreasing, to realize the lifting function of the waste collection box and reduce the impact noise generated by the falling waste during the collection process.

[0031] Specifically, the chain lift of this utility model is a forklift lift located below the strip rolling shear in the metal strip surface treatment production line. The waste material after strip shearing falls into the waste collection box. When it falls, it impacts the waste material inside the box, generating noise. The material box can be raised when collecting waste material to reduce noise.

[0032] like Figure 1-4 As shown, the chain lift of this utility model includes: a lifting fixed bracket (1), a lifting seat (2), a lifting guide rail (3), a counterweight bracket (4), a counterweight guide rail (5), a lifting chain (6), a power component (7), a guide wheel assembly (8), a fork (9), and a limit switch (10); the lifting fixed bracket (1) is fixed to the ground and is the supporting component of the entire equipment; the lifting guide rail (3), the counterweight guide rail (5), the power component (7), and the guide wheel assembly (8) are installed on the lifting fixed bracket (1) to form a whole.

[0033] The lifting seat (2) and the forks (9) are fixed together by bolts. The lifting guide wheel (2-1) is installed on the lifting seat (2), so that the lifting seat (2) can move up and down along the lifting guide rail (3). The lifting seat (2) and the forks (9) are lifted as a whole by the lifting chain (6). One end of the lifting chain (6) is connected to the lifting seat (2). The lifting seat (2) moves up and down along the lifting guide rail (3) through the lifting guide wheel (2-1). The other end of the lifting chain (6) is connected to the counterweight bracket (4). The counterweight bracket (4) pulls the lifting seat (2) to move up by gravity.

[0034] The counterweight guide wheel (4-1) is installed on the counterweight bracket (4), so that the counterweight bracket (4) can move up and down along the counterweight guide rail (5).

[0035] One end of the lifting chain (6) is connected to the lifting seat (2), and the other end is connected to the counterweight bracket (4) through the power shaft assembly (7-2) and guide wheel assembly (8) of the power assembly (7).

[0036] The limit switch (10) is set on the counterweight guide rail (5) to set the lower limit of the counterweight bracket (4), control the lowest position of the counterweight bracket (4), and correspondingly limit the highest position (upper limit) of the lifting seat (2).

[0037] The power assembly (7) includes a power motor (7-1), a power shaft assembly (7-2), and a power chain (7-3). The power motor (7-1) has an output sprocket mounted on its shaft end, which is connected to the power sprocket (7-2-1) on the shaft end of the power shaft assembly (7-2) via the power chain (7-3). This enables the transmission sprocket (7-2-2) of the power shaft assembly (7-2) to rotate, thereby driving the lifting chain (6) to rise and fall. Figure 5 As shown, the power shaft assembly (7-2) includes a power sprocket (7-2-1) and a transmission sprocket (7-2-2).

[0038] like Figure 6 As shown, the guide wheel assembly (8) includes a guide sprocket (8-2) and a lifting chain (6) that passes around the guide sprocket (8-2) to change the direction of motion.

[0039] like Figure 7 , 8 As shown, the counterweight support (4) is a frame structure with a certain weight, and various weights of counterweight blocks can be set in the frame structure according to actual needs.

[0040] This utility model's chain-driven lifting mechanism primarily functions to lift a waste collection box. Specifically, the waste collection box is placed on the forks and lifted to collect waste. Lifting the box shortens the distance to the waste outlet, reducing noise generated by the impact of falling waste. Because the chain-driven lifting mechanism achieves counterweight balance through a counterweight bracket, waste collection can be performed without power, or the lifting of the waste collection box can be controlled by a power unit. When the lifting is controlled by the power unit, the counterweight balance function reduces the required lifting power. The lifting power can be a motor, hydraulic cylinder, or electric cylinder, and the lifting guide uses forklift rollers, which helps reduce costs.

[0041] This patented equipment mainly realizes the function of lifting the collection box. It is used in the metal sheet and strip post-processing production line. By increasing the height of the waste collection box, the drop height of the waste is reduced, the impact noise is reduced, and the on-site operating environment is improved.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
