Description

Technical Field

[0001] This utility model relates to the field of electric hoist technology, and more specifically to an improved chain guide device. Background Technology

[0002] In various fields such as stage construction, factories, mines, and ports, there is a need for lifting components, requiring the use of cranes or electric hoists. These components are generally lifted using chains. However, after a certain period of operation, the cranes or electric hoists require maintenance, replacement, or adjustment of the chains. In current technology, maintenance, replacement, or adjustment requires disassembling the relevant components inside the housing, performing the work, and then reinstalling the disassembled parts afterward, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an improved chain guide device with a reasonable structure and convenient maintenance.

[0004] An improved chain guiding device includes a housing and a chain. Two chain guide frames with a split structure are fitted inside the housing. A chain pressing frame is fitted inside the housing below the two chain guide frames. The chain is pressed into the two chain guide frames, extending downwards to fit against the chain pressing frame. The two chain guide frames abut against the chain pressing frame. A chain guide plate is provided above the housing, covering the two chain guide frames and sealing the housing. A chain guiding mechanism is provided on one side of the housing.

[0005] This practical design features a reasonable structure. Maintenance, replacement, or adjustment of the chain only requires removing one side of the chain guide frame, saving time and effort. A guiding mechanism is also included to effectively guide the chain as it ascends or descends, allowing for linear movement without damaging other parts.

[0006] As a further improvement and supplement to the above solution, this utility model also includes the following additional technical features: The guiding mechanism includes a first protrusion on the chain guide plate and two hanging plates spaced apart on the housing. One end of each hanging plate is fixed by a fixing plate, and one side of the chain guide plate with the first protrusion extends out of the housing. This guiding mechanism effectively guides the chain as it ascends or descends, preventing damage to other parts.

[0007] The box body is provided with a second protrusion, and the guide plate is set on the second protrusion. The second protrusion is provided for two reasons: firstly, it facilitates the processing of the box body, and secondly, it increases the strength of the box body.

[0008] The chain guide frame is equipped with a first arc-shaped groove and a second arc-shaped groove with an angle setting. The chain is positioned appropriately.

[0009] The first protrusion is a ring-shaped arc structure, with a reinforcing rib on one side below it. It has good strength and wear resistance.

[0010] The chain clamp has a recessed groove, ensuring proper chain placement.

[0011] The fixing plate is snapped onto the lugs of the housing and secured with cotter pins. Assembly and disassembly are quick and easy.

[0012] The lower side of the guide chain frame has a through structure, which, together with the pressure chain frame, forms an observation window. This facilitates daily observation.

[0013] The following advantages can be achieved by using this utility model: The structure is reasonable, and when maintaining, replacing, or adjusting the chain, only one side of the chain guide frame needs to be removed, saving time and effort. At the same time, a guiding mechanism is provided to effectively guide the chain as it rises or falls, allowing for linear ascent or descent without damaging other parts. Attached Figure Description

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-11 As shown, this utility model is an improved chain guide device.

[0027] The improved chain guide device described in this embodiment includes a housing 1 and a chain 3. Two detachable chain guide frames 4 are fitted inside the housing 1. Below the two chain guide frames 4 is a chain pressing frame 5 fitted inside the housing 1. The chain 3 is pressed into the two chain guide frames 4, extending downwards to fit against the chain pressing frame 5. The two chain guide frames 4 abut against the chain pressing frame 5. A chain guide plate 2 is provided above the housing 1, covering the two chain guide frames 4 and sealing the housing 1. A chain guiding mechanism is provided on one side of the housing 1. Bolts pass through the chain guide plate 2 and the chain guide frames 4 to fix the chain to the housing 1.

[0028] Furthermore, the guiding mechanism includes a first protrusion 21 on the guide plate 2 and two hanging plates 6 spaced apart on the housing 1; one end of each hanging plate 6 is fixed by a fixing plate 7, and the guide plate 2 with the first protrusion 21 extends out of the housing 1. Connecting shafts 9 are provided on the two hanging plates 6, passing through fixing protrusions on the housing 1 for fixation. The chain 3 passes through the guide frame 4, exits from above the guide plate 2, passes through the first protrusion 21 on the guide plate 2, and finally falls between the two hanging plates 6.

[0029] Furthermore, the box body 1 is provided with a second protrusion 11, and the guide plate 2 is disposed on the second protrusion 11.

[0030] Furthermore, the guide frame 4 is provided with a first arc-shaped groove 41 and a second arc-shaped groove 42 set at an angle, and the chain 3 is located in the first arc-shaped groove 41 and the second arc-shaped groove 42. In this embodiment, the first arc-shaped groove 41 and the second arc-shaped groove 42 are set at 90 degrees.

[0031] Furthermore, the first protrusion 21 is an annular arc structure, and a reinforcing rib 22 is provided on one side below the first protrusion 21 to strengthen the structure.

[0032] Furthermore, the chain pressing frame 5 is provided with a concave groove, and in this embodiment, the chain pressing frame 5 has an arc-shaped structure.

[0033] Furthermore, the fixing plate 7 is snapped onto the lug of the housing 1 and fixed with a cotter pin 10. The pin 8 passes through the lug of the housing 1 and the fixing plate 7, and is fixedly connected with the cotter pin 10.

[0034] Furthermore, the lower side of the guide chain frame 4 is provided with a through structure, which is an arc-shaped structure and forms an observation window with the pressure chain frame 5.

[0035] When this improved chain guide device is in use, if chain maintenance, replacement, or adjustment is required, simply unscrew the fixing bolts on the chain guide plate 2, remove the chain guide plate 2 and the chain guide frame 4 on one side, saving time and effort. After completion, snap the chain guide frame 4 on one side back in place and tighten the fixing bolts on the chain guide plate 2.

[0036] The above are preferred embodiments of the present utility model and do not limit the scope of protection of the present utility model.
