[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A chain connection auxiliary device, the structure of which can be Figure 1-Figure 5 As shown in the figure, in this embodiment, the chain connection auxiliary device includes: a base 1, an operating block 2 and a lifting block 3, wherein the base 1 is used to provide an installation foundation for the chains to be spliced ​​and other components in the device, the operating block 2 is used to drive one chain to be spliced ​​close to another chain to be spliced, and the lifting block 3 is used to drive the end chain links of the two chains to be spliced ​​to bend upward, so as to facilitate the operation of the staff.

[0028] Specifically, a receiving groove 11 for receiving the chain to be spliced ​​is provided on the top surface of the base 1, and a guide oblong hole 12, an installation cutout 13 and a first positioning column 41 are provided inside the receiving groove 11, and the guide oblong hole 12 and the first positioning column 41 should be located on both sides of the installation cutout 13, respectively. A receiving cavity 14 is also provided inside the base 1, and the guide oblong hole 12 and the installation cutout 13 are both connected to the receiving cavity 14. During assembly, the staff can slide the operating block 2 inside the receiving cavity 14, and set the lifting block 3 inside the installation cutout 13 in a liftable manner. Figure 4 As shown, in this embodiment, a first guide slope 31 is provided on the side wall of the lifting block 3 close to the operating block 2, and a second guide slope 21 is provided on the side wall of the operating block 2 close to the lifting block 3. When the operating block 2 slides in the direction close to the lifting block 3, the contact between the second guide slope 21 and the first guide slope 31 can enable the lifting block 3 to move upward. When the operating block 2 slides in the direction away from the lifting block 3, the separation of the second guide slope 21 and the first guide slope 31 can obtain sufficient space under the lifting block 3, thereby facilitating the lifting block 3 to move downward under the action of its own gravity.

[0029] Optionally, in order to facilitate driving the operating block 2 to slide, this embodiment may further include an operating screw 5. Figure 5As shown, a threaded hole 15 connected to the accommodating cavity 14 is provided on the side wall of the base 1. During assembly, the operating screw 5 should be placed inside the threaded hole 15, and the end of the operating screw 5 is rotatably connected to the side wall of the operating block 2 away from the lifting block 3. When the operating block 2 needs to slide, the staff can rotate the operating screw 5 to flexibly adjust the position of the operating block 2, which is convenient for connecting the chain.

[0030] In addition, in order to prevent the lifting block 3 from deflecting during the lifting process, a guide bar 32 may be provided on the side wall of the lifting block 3, and a guide groove 131 for accommodating the guide bar 32 should be provided on the inner side wall of the installation cutout 13. When the lifting block 3 is lifted and lowered, the cooperation of the guide bar 32 and the guide groove 131 can guide the movement direction of the lifting block 3 to prevent the lifting block 3 from deflecting.

[0031] In order to facilitate the control of the position of the chain to be spliced ​​inside the receiving groove 11, a second positioning column 42 is also provided on the top surface of the operating block 2, and the second positioning column 42 is inserted into the receiving groove 11 through the guiding oblong hole 12. When in use, the staff should put the two chains to be spliced ​​into the receiving groove 11, and insert the first positioning column 41 and the second positioning column 42 into the gap between the chain links of the two splicing chains near the splicing area. Figure 1 and Figure 3 As shown, at this time, the first positioning column 41 can fix one of the chains inside the receiving groove 11 to prevent the chain from moving, and the second positioning column 42 can slide with the operating block 2, thereby driving the other chain to approach or move away from the chain fixed by the first positioning column 41, thereby facilitating the alignment connection between the two chains. Figure 2 and Figure 4 As shown, at this time, the operating block 2 slides to the extreme position in the direction close to the lifting block 3, and the lifting block 3 is in an ascending state. The rise of the lifting block 3 can make the end chain links of the two chains to be spliced ​​bend upward, thereby providing a larger operating space for the staff and facilitating the chain connection work.

[0032] Optionally, in order to realize the installation of the first positioning column 41 and the second positioning column 42, the present embodiment may provide a first mounting screw hole 16 on the side of the mounting cutout 13 in the receiving groove 11 away from the guide oblong hole 12, and provide a second mounting screw hole 22 on the top surface of the operating block 2. Accordingly, a first threaded column 411 may be provided at the bottom end of the first positioning column 41, and a second threaded column 421 may be provided at the bottom end of the second positioning column 42. During installation, the staff may detachably insert the first threaded column 411 into the first mounting screw hole 16, thereby installing the first positioning column 41 on the base 1, and detachably insert the second threaded column 421 into the second mounting screw hole 22, thereby installing the second positioning column 42 on the operating block 2.

[0033] In addition, since chains of different specifications have different chain link lengths, in order to improve the scope of application of the device, a plurality of first mounting screw holes 16 can be provided, and the plurality of first mounting screw holes 16 should be evenly arranged along the length direction of the receiving groove 11. When in use, the staff can adjust the installation position of the first positioning column 41 according to the actual specifications of the chain to be spliced, so that the end chain link of the chain to be spliced ​​is on the top surface of the lifting block 3 after positioning is completed.

[0034] As an optional implementation of this embodiment, in order to prevent the end of the chain to be spliced ​​from separating from the lifting block 3, a silicone anti-skid pad (not shown in the figure) can be provided on the top surface of the lifting block 3. The silicone anti-skid pad can increase the friction coefficient between the chain link and the device, so that the end chain link of the chain to be spliced ​​bends upward following the rise of the lifting block 3.

[0035] The effects of the above scheme are described below:

[0036] This embodiment provides a chain connection auxiliary device, which can position two chains to be spliced ​​through a first positioning column and a second positioning column, thereby facilitating the alignment of the two chains. Secondly, the device can drive the second positioning column to move through the operating block, thereby facilitating one chain to approach another chain and facilitate chain connection. In addition, the lifting block of the device can be raised and lowered following the sliding of the operating block, so that the end chain links of the two chains bend upward, thereby providing a larger operating space for chain connection.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
