Description

Technical Field

[0001] This utility model relates to the field of chain tension adjustment technology, specifically to an auxiliary tool for adjusting the tension of a chain conveyor chain. Background Technology

[0002] Chain conveyors use chains as traction and load-bearing components to transport materials, enabling them to quickly and accurately move goods from one area to another, thus improving logistics efficiency.

[0003] Currently, chain tension is adjusted by changing the position of the sprockets. Confirming the tension involves maintenance personnel lifting each chain and visually or manually feeling the tension. This reliance on experience can easily lead to improper tension on the two or four chains on either side. Overly tight chains increase power consumption and cause bearing wear, while overly loose chains increase wear and can even cause chain derailment. Furthermore, if the two chains on the same side have different tensions, the conveyed items will tilt towards the side with the tighter chain, affecting the stability of material transport.

[0004] Therefore, a device is needed to easily confirm the tension of each chain, in order to assist in adjusting the tension of the chain conveyor. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an auxiliary tool for adjusting the chain tension of a chain conveyor. By using a lifting plate pressed down on the chain, the lifting plate moves along a guide rod. The amount of movement of the lifting plate directly reflects the chain tension, thereby improving the convenience and accuracy of chain tension adjustment. It also improves the consistency of chain tension on both sides of the chain conveyor, ensuring the stability of material conveying.

[0006] Specifically, this utility model provides an auxiliary tool for adjusting the tension of a chain conveyor chain, comprising:

[0007] Base;

[0008] A lifting plate is located above the base and is connected to the base via an elastic element. The lifting plate is used to support the chain in order to compress the elastic element.

[0009] A guide rod is disposed between the lifting plate and the base, and the lifting plate is slidably connected to the guide rod.

[0010] Furthermore, the guide rod is provided with a scale.

[0011] Furthermore, the lower end of the guide rod is connected to the base via threads, and the upper end is a nut.

[0012] Furthermore, the lifting plate is concave in shape, with a groove in the middle for placing the chain.

[0013] Furthermore, anti-slip pads are provided in both the placement slot and the bottom of the base.

[0014] The working principle of this utility model:

[0015] When using the tool, place it between the chain and the graphite trough of the chain conveyor, place the trough to support the chain, and press down the lifting plate when the chain is tensioned. The lifting plate will descend along the guide rod, and the amount of movement of the lifting plate is the current tension of the chain. Record the scale value at this time. Then place it on another chain and adjust the chain tension to the recorded scale value to ensure that the tension of the two chains is consistent.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) The auxiliary device provided by this utility model can intuitively reflect the tightness of the chain by the amount of movement of the lifting plate, thereby improving the convenience and accuracy of chain tightness adjustment.

[0018] (2) This device can assist in the quantitative adjustment of the chain tension, thereby improving the consistency of the chain tension on both sides of the chain conveyor and ensuring the stability of material conveying. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1-2As shown, this embodiment provides an auxiliary tool for adjusting the chain tension of a chain conveyor, including: a base 1, a lifting plate 2, a spring 4, and two guide rods 3. The base 1 and the lifting plate 2 are connected by the spring 4. The two guide rods 3 are located on both sides of the spring 4 and serve as guides for the movement of the lifting plate 2. The guide rods 3 are marked with scales to observe the amount of movement of the lifting plate 2. This tool is placed between the chain 51 and the graphite trough of the chain conveyor 5. By pressing down on the lifting plate 2 with the chain 51, the spring 4 is compressed, causing the lifting plate 2 to move along the guide rods 3. The amount of movement is reflected by the scales, which can accurately adjust the tension of the chains 51 on both sides of the chain conveyor 5, making the tension of the two chains as consistent as possible, thereby ensuring the stability of material conveying and preventing the items from tilting towards the side with the tighter chain due to different tensions of the chains 51 on both sides.

[0028] Specifically, the bottom of the base 1 has an anti-slip pad (not shown) to prevent it from sliding on the graphite groove during use and to improve stability. Two screw holes are provided on the base 1 for threaded connection to the bottom of the guide rod 3, thus fixing the guide rod 3 to the base 1.

[0029] The lifting plate 2 is concave in shape, with a groove 21 in the middle for placing the chain 51. An anti-slip pad 22 is installed inside the groove 21 to prevent the chain 51 from sliding within it. Through holes are provided on both sides of the lifting plate 2, through which the guide rod 3 passes, allowing the lifting plate 2 to be fitted onto the guide rod 3. The upper part of the guide rod 3 has a nut for easy disassembly and for limiting the position of the lifting plate 2.

[0030] Specifically, such as Figure 3-4 As shown, in use, the base 1 of the tool is placed between the chain 51 and the graphite groove. After the guide rod 3 passes through the through hole on the lifting plate 2 and is connected and fixed to the screw hole on the base 1, the chain 51 is placed in the placement groove 21. When the chain 51 is tensioned, the lifting plate 2 is pressed down, and the lifting plate 2 descends along the guide rod 3. The amount of movement of the lifting plate 3 is the current tension of the chain 51. Record the scale value at this time. Then place it on another chain 51 and adjust the tension of the chain 51 to the recorded scale value to ensure that the tension of the two chains is consistent. This tool can effectively improve the convenience of adjusting the tension of the chain 51 and ensure the consistency of the tension of the chains on both sides.

[0031] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
