AI Technical Summary
In existing overhead chain conveyor systems, the chain is too loose after being installed on the track frame, which affects the transmission stability and is prone to loosening during long-term operation, leading to instability in the chain-sprocket transmission.
The ring frame structure is adopted. The chain tensioning component, including a fixed pulley, a traction rope and a counterweight, applies force to move the second mounting frame away from the first mounting frame, thereby achieving the tensioning of the ring chain and avoiding loosening and skipping of teeth.
This improves the transmission stability of the overhead chain conveyor, prevents the chain from loosening and detaching from the sprocket, and ensures the stability and reliability of the transmission.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of workpiece processing equipment, and in particular to a suspended chain conveyor device. Background Technology
[0002] A suspended chain workpiece cleaning system typically includes a suspended chain, a suspended chain conveyor, and multiple workpiece processing stations. The suspended chain is used to suspend workpieces (such as flywheel housings, automotive brake pads, equipment parts, etc.), while the suspended chain conveyor is used to drive the suspended chain and workpieces sequentially through different workpiece processing stations to achieve workpiece processing (such as cleaning, drying, etc.).
[0003] Existing overhead conveyor systems typically include a chain and a sprocket. The sprocket is connected to the workpiece overhead chain and engages with the chain for transmission, thereby enabling the conveying of the overhead chain and the workpiece.
[0004] However, in existing overhead chain conveyor systems, the chain is typically installed directly inside the track frame. To reduce installation difficulty, the chain size is usually slightly larger than the track frame, which can lead to it being too loose after installation, thus affecting the transmission stability between the chain and the sprocket. Furthermore, during long-term operation, the force between the chain and the sprocket can easily cause the chain to loosen, further affecting the transmission stability between the chain and the sprocket. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a suspended chain conveyor device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A suspended chain conveyor includes a main frame, an annular chain, and an annular frame for mounting the annular chain;
[0008] The ring frame includes a first mounting frame and a second mounting frame;
[0009] The first mounting bracket is fixedly mounted on the main frame, and the second mounting bracket is slidably mounted on one end of the first mounting bracket, forming the annular frame with the second mounting bracket.
[0010] It also includes a chain tensioning assembly that can apply a force to the second mounting bracket away from the direction of the first mounting bracket.
[0011] Preferably, the chain tensioning assembly includes a fixed pulley, a traction rope, and several counterweights;
[0012] The fixed pulley is rotatably mounted on the main frame;
[0013] One end of the traction rope is connected to the second mounting frame, and the other end passes around the fixed pulley and is detachably connected to several of the counterweights.
[0014] Preferably, the traction rope and the counterweight are connected by a connector;
[0015] The connector includes a lifting ring, a hook, and a mounting rod;
[0016] Of the lifting ring and the hook, one is connected to the traction rope, and the other is connected to the mounting rod;
[0017] The mounting rod is used to mount the counterweight.
[0018] Preferably, the mounting rod is configured as a rigid rod, and its end away from the hook is provided with a support plate for supporting the counterweight;
[0019] The counterweight has a slot that engages with the mounting rod.
[0020] Preferably, the fixed pulley has a groove on its circumferential surface;
[0021] The inner wall of the traction rope abuts against the inner wall of the groove.
[0022] Preferably, the first mounting bracket has horizontal sections distributed at different heights, and inclined connecting sections connecting two adjacent horizontal sections.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] This utility model provides a suspended chain conveyor device in which a first mounting frame and a second mounting frame are slidably connected to each other and form a ring frame. During installation, the second mounting frame can be moved closer to the first mounting frame, so that the edge length of the ring area formed by the two is smaller, which facilitates the installation of the ring chain. After the ring chain is installed into the ring frame, the chain tensioning component can apply a force to the second mounting frame away from the first mounting frame, so that after the ring chain is installed into the ring frame, it can drive the second mounting frame to move away from the first mounting frame, increasing the edge length of the ring area formed by the two, thereby achieving tension of the ring chain, preventing the ring chain from loosening and causing tooth skipping (the chain detaching from the sprocket during operation), and thus avoiding affecting the stability of its transmission.

Detailed Implementation
[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0040] See Figures 1 to 5 This utility model provides a suspended chain conveyor device, including a main frame 1, an annular chain 2, an annular frame 3, and a chain tensioning assembly 4. The annular frame 3 is used to install the annular chain 2.
[0041] Specifically, the ring frame 3 includes a first mounting frame 31 and a second mounting frame 32; the first mounting frame 31 is fixedly mounted on the main frame 1, and the second mounting frame 32 is slidably mounted on one end of the first mounting frame 31, forming a ring frame 3 together with the second mounting frame 32; the chain tensioning assembly 4 can apply a force to the second mounting frame 32 away from the first mounting frame 31, thereby tightening the ring chain 2.
[0042] It is easy to understand that in the above scheme, the first mounting bracket 31 and the second mounting bracket 32 are slidably connected to each other and form a ring frame 3. During installation, the second mounting bracket 32 can be moved closer to the first mounting bracket 31, so that the edge length of the ring area formed by the two is smaller, which facilitates the installation of the ring chain 2. After the ring chain 2 is installed into the ring frame 3, the chain tensioning component 4 can apply a force to the second mounting bracket 32 away from the first mounting bracket 31, so that after the ring chain 2 is installed into the ring frame 3, it can drive the second mounting bracket 32 to move away from the first mounting bracket 31, increasing the edge length of the ring area formed by the two, thereby achieving tension of the ring chain 2, so as to avoid the ring chain 2 from loosening and causing tooth skipping (the chain disengaging from the sprocket during operation), and thus avoiding affecting the stability of its transmission.
[0043] The chain tensioning assembly 4 can be configured in various ways to apply a force to the second mounting bracket 32 away from the first mounting bracket 31, so as to tighten the ring chain 2.
[0044] See Figures 1 to 4 In this embodiment, the chain tensioning assembly 4 includes a fixed pulley 41, a traction rope 42, and several counterweights 43. The fixed pulley 41 is rotatably mounted on the main frame 1. One end of the traction rope 42 is connected to the second mounting frame 32, and the other end passes around the fixed pulley 41 and is detachably connected to several counterweights 43. Thus, by increasing or decreasing the number of counterweights 43 connected to the traction rope 42, different forces can be applied to the second mounting frame 32 to ensure the tensioning effect of the ring chain 2. At the same time, it can also avoid the hidden dangers of transmission efficiency and accelerated wear caused by excessive tension of the ring chain 2.
[0045] Furthermore, the traction rope 42 and the counterweight 43 are connected by a connector 5; the connector 5 includes a lifting ring 51, a hook 52 and a mounting rod 53; of the lifting ring 51 and the hook 52, the lifting ring 51 is connected to the traction rope 42 and the hook 52 is connected to the mounting rod 53; the mounting rod 53 is used to install the counterweight 43, which facilitates the assembly of the entire chain tensioning assembly 4 and the second mounting frame 32, and also facilitates the addition or reduction of the number of counterweights 43.
[0046] Furthermore, the mounting rod 53 is configured as a rigid rod, and its lower end is provided with a support plate 54 for supporting the counterweight 43; the counterweight 43 is provided with a slot 431 that engages with the mounting rod 53. Of course, in other embodiments, the counterweight 43 and the mounting rod 53 may also be configured as a threaded connection or a limiting connection through a limiting post and limiting hole.
[0047] Furthermore, the fixed pulley 41 has a groove 411 on its circumferential surface; the inner wall of the traction rope 42 abuts against the inner wall of the groove 411 to limit the traction rope 42 and prevent the traction rope 42 from deviating.
[0048] Of course, in other embodiments, the chain tensioning assembly 4 can also be directly set as a telescopic cylinder or an electric actuator, etc.
[0049] See Figure 5 The first mounting bracket 31 has horizontal sections 311 distributed at different heights, and inclined connecting sections 312 connecting two adjacent horizontal sections 311.
[0050] It is easy to understand that the horizontal section 311 and the inclined connecting section 312 of the first mounting bracket 31 are designed to allow the workpiece to be at different heights at different workstations. For example, it is located at a relatively high position during spray cleaning and at a relatively low position during ultrasonic cleaning. Simultaneously, the cooperation between the first mounting bracket 31 and the second mounting bracket 32 also ensures the stable installation of the ring chain 2. In other words, it satisfies both the different height requirements of the workpiece at different workstations and the requirement for stable installation of the ring chain 2 to prevent loosening.
[0051] Furthermore, the horizontal section 311 and the inclined connecting section 312 are connected by an arc to further enhance the installation effect of the ring chain 2 and the first mounting bracket 31.
[0052] See Figure 1 To facilitate the stable installation of the main frame 1 and the ring frame 3, the main frame 1 includes a bracket 11 and a support column 12 for supporting the bracket 11; the first mounting frame 31 is fixedly connected to the bracket 11; the second mounting frame 32 is slidably connected to the bracket 11 through a slider 6.
[0053] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
