[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0023] See Figures 1 to 3This disclosure provides a chain connection auxiliary device for connecting the two ends of a broken chain 1. The chain connection auxiliary device includes two hook assemblies 2 and an adjustment assembly 3. The two hook assemblies 2 are respectively connected to the two ends of the chain 1. The adjustment assembly 3 is connected between the two hook assemblies 2 and is configured to adjust the distance between the two hook assemblies 2 to adjust the relative position of the two ends of the chain 1 in the horizontal direction. Two hook assemblies 2 can connect the two ends of a broken chain 1 to facilitate auxiliary connection of the broken chain 1; the adjusting assembly 3 can adjust the distance between the two hook assemblies 2 to adjust the relative position of the two ends of the chain 1 in the horizontal direction to meet the tightness and tension requirements of the broken chain 1 connection, ensuring that the reconnected chain 1 can return to its pre-breakage state; the chain connection auxiliary device can quickly and effectively connect the two ends of the broken chain 1 to facilitate auxiliary connection of the broken chain 1, saving time and effort, reducing labor intensity and personnel safety risks, improving the connection efficiency and safety of the chain 1, and ensuring that the connected chain 1 has sufficient stability, reducing equipment downtime losses; moreover, this chain connection auxiliary device is highly versatile and can be applied to the auxiliary connection of all types of scraper chains, such as straight and ring chains.
[0024] Preferably, the adjusting component 3 is configured to adjust the relative position of the two hook assemblies 2 in the vertical direction, thereby adjusting the relative position of the two ends of the chain 1 in the vertical direction. By adjusting the relative position of the two ends of the chain 1 in the vertical direction through the adjusting component 3, the extension direction of the broken chain 1 is restored to the extension direction of the chain 1 before breakage. This not only ensures that the chain 1 maintains its original tension distribution and geometry after reconnection, but also minimizes the risk of stress concentration or deformation caused by chain 1 breakage and reconnection, improving the safety and reliability of the reconnected chain 1. At the same time, by raising the two hook assemblies 2 in the vertical direction, the space below the chain connection auxiliary device is increased, making it easier for operators to reconnect the broken chain 1, thus facilitating operation.
[0025] As one example, see Figure 4The chain 1 includes an outer chain plate 11, an inner chain plate 12, a pin 13, and a roller 14. The hook assembly 2 connects to the roller 14 of the unbroken part of the chain 1, and the relative position of the two ends of the chain 1 is adjusted by the adjusting assembly 3 to ensure that the chain 1 returns to its original state after reconnection. After the chain 1 breaks, the outer chain plate 11, inner chain plate 12, pin 13, and roller 14 between the two ends of the chain 1 need to be reinstalled, which requires a large installation space. By adjusting the relative position of the two hook assemblies 2 in the vertical direction, the two hook assemblies 2 are raised to ensure that there is a large installation space when connecting the two ends of the broken chain 1, which facilitates the connection operation of the broken chain 1 by the operator and improves the connection efficiency of the chain 1.
[0026] Preferably, see Figures 1 to 3 The adjusting component 3 includes two adjusting rods 31 and a connector 32. One end of each adjusting rod 31 is connected to one of the two hook assemblies 2, and the connection length between the adjusting rod 31 and the hook assembly 2 is adjustable. The connector 32 is rotatably connected between the two adjusting rods 31, so that the connection angle between the connector 32 and the adjusting rod 31 is adjustable. The adjustable length of the connection between the adjusting rod 31 and the hook assembly 2 allows for adjustment of the distance between the two hook assemblies 2, thereby adjusting the relative position of the two ends of the chain 1 in the horizontal direction and adjusting the tension of the chain 1 to ensure that the reconnected chain 1 can return to its original state. The adjustable angle between the connector 32 and the adjusting rod 31 allows for adjustment of the relative position of the two hook assemblies 2 in the vertical direction along with the two adjusting rods 31, thereby adjusting the relative position of the two ends of the broken chain 1 in the vertical direction. By adjusting the relative position of the two ends of the chain 1 in the horizontal and vertical directions, the extension direction of the broken chain 1 is restored to the extension direction of the chain 1 before it was broken, improving the safety and reliability of the reconnected chain 1.
[0027] As described above, the connection length between the adjusting rod 31 and the hook assembly 2 can be adjusted in various ways, for example... Figures 1-3 In the illustrated embodiment, one end of the adjusting rod 31 is provided with an external thread and passes through the hook assembly 2 to be threadedly connected to the first nut 33. By rotating the first nut 33, the connection length between the adjusting rod 31 and the hook assembly 2 is adjusted, thereby precisely adjusting the distance between the two ends of the broken chain 1. In other embodiments, the adjusting rod 31 is a threaded rod.
[0028] In the above-described manner, by rotatably connecting the connector 32 between the two adjusting rods 31, the connection angle between the connector 32 and the adjusting rods 31 in the horizontal and / or vertical directions can be adjusted. In some embodiments, the axis of rotation between the connector 32 and the adjusting rods 31 is perpendicular to the axial direction of the adjusting rods 31, so that the connection angle between the connector 32 and the adjusting rods 31 in the vertical direction can be adjusted.
[0029] Specifically, such as Figures 1-3 As shown, the connector 32 includes two connecting plates 321, which are arranged radially apart along the adjusting rod 31 and fixedly connected at both ends by a first bolt 34. The corresponding ends of the adjusting rod 31 are formed into collars fitted onto the first bolts 34. The connection between the two connecting plates 321 and the adjusting rod 31 makes the connection between the connecting plates 321 and the adjusting rod 31 more stable and secure.
[0030] In one embodiment, the first bolt 34 passes through one of the connecting plates 321, the adjusting rod 31, and the other connecting plate 321 and is threadedly connected to the second nut 35, ensuring the stability of the connection between the connecting plate 321 and the adjusting rod 31; and when it is necessary to adjust the connection angle between the adjusting rod 31 and the connecting member 32, the second nut 35 is loosened, the adjusting rod 31 is rotated to the desired position, and the second nut 35 is tightened to lock the first bolt 34, thereby realizing the adjustment and fixation of the connection angle between the adjusting rod 31 and the connecting member 32.
[0031] Preferably, there are two adjusting components 3, which are spaced apart between the two hook assemblies 2. The spacing between the two adjusting components 3 improves the firmness of the connection between the two hook assemblies 2 and prevents swaying between the two hook assemblies 2, thus ensuring the stability of the position of the hook assemblies 2.
[0032] Preferably, the hook assembly 2 includes a hook base 21 and a hook 22. The hook base 21 is connected to the adjusting assembly 3, and the hook 22 is disposed on the hook base 21 and used to connect the end of the chain 1. The hook 22 can withstand the load transmitted by the chain 1, ensuring that the chain 1 will not disengage when connected to the hook 22. The connection between the hook base 21 and the adjusting assembly 3 allows adjustment of the relative position between the two hooks 22, thereby adjusting the relative position of the two ends of the broken chain 1.
[0033] As one embodiment, the hook base 21 is provided with a through hole, and the adjusting rod 31 passes through the through hole and is threadedly connected to the first nut 33 to ensure that the adjusting rod 31 and the hook assembly 2 are detachably connected.
[0034] Preferably, a groove 23 is provided on the inner side of the hook 22, which is used to prevent the end of the chain 1 from detaching from the hook 22; and / or the hook 22 is detachably connected to the hook base 21. By inserting the chain 1 into the groove 23 of the hook 22, the chain 1 is less likely to slip out of the hook 22. At the same time, the groove 23 increases the contact area between the chain 1 and the hook 22, further improving the firmness and stability of the connection between the chain 1 and the hook 22, and ensuring the safety of the chain 1 during the connection process. The detachable connection between the hook 22 and the hook base 21 makes the replacement and maintenance of the hook 22 more convenient, reduces maintenance costs and time, and improves maintenance efficiency.
[0035] Preferably, the hook 22 is rotatably connected to the hook base 21 to adjust the connection angle between the hook 22 and the hook base 21. The vertical position of the hook base 21 is adjusted by the adjusting component 3, so that the hook base 21 is raised, which facilitates the reconnection of the broken chain 1 below the hook base 21. At the same time, by adjusting the connection angle between the hook 22 and the hook base 21, the hook base 21 can be moved vertically to ensure that the hook 22 and the chain 1 are stably connected.
[0036] Preferably, two ear plates 24 are fixedly provided on the side of the hook base 21 away from the adjusting assembly 3. The two ear plates 24 are connected by a second bolt 25. The hook 22 is disposed between the two ear plates 24 and is threaded through by the second bolt. By clamping the hook 22 with the two ear plates 24, a stable support is provided for the hook 22, improving the stability and firmness of the connection between the hook 22 and the hook base 21. The connection between the second bolt 25 and the hook 22 and the ear plates 24 facilitates the disassembly and replacement of the hook 22.
[0037] As one embodiment, the ear plate 24 is fixedly installed on the hook base 21 by welding.
[0038] As one example, such as Figure 3 As shown, the second bolt 25 passes through one of the ear plates 24, the hook 22 and the other ear plate 24 in sequence and is threadedly connected to the third nut 26, so that the hook 22 and the hook base 21 can be detachably connected, and the connection angle between the hook 22 and the hook base 21 can also be adjusted.
[0039] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. This includes combining various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
