DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] Example

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the chain continuous processing forming protection device includes a protection mechanism 10, an anti-sway mechanism 20, a lifting mechanism 30, a column 40 and a traction mechanism 50. The protection mechanism 10 includes a protection cover 11 and a protection cover 2 13. A hinge 19 is installed on one side of the protection cover 11 and the protection cover 2 13. The protection cover 2 13 is installed with an observation window 131, and two operation ports 132 are respectively located on both sides of the observation window 131. Several anti-sway mechanisms 20 are located between the protection cover 1 1 and the protection cover 2 13. The anti-sway mechanism 20 includes a spline shaft 25, a baffle 26 and a clamping plate 27. The baffle 26 is fixedly sleeved on the outer ring of the spline shaft 25, and the clamping plate 27 is movably sleeved on the outer ring of the spline shaft 25. A spring 28 is fixedly connected between the baffle 26 and the clamping plate 27.

[0035] It should be noted that the anti-sway mechanism 20 is provided with at least four groups, every two groups are located on the same plane and are mirrored, the column 40 is provided with multiple workstations, such as continuous chain weaving, closed-loop welding, weld grinding and other workstations, the traction mechanism 50 is used to control the movement of the chain, and the lifting mechanism 30 is used to control the height of the protective mechanism 10, so that workers of different heights can use it.

[0036] Specifically, the chain passes through the middle of the protective cover 1 11 and the protective cover 2 13 to shield the flying sparks and molten droplets. At the same time, the clamp 27 fixes the chain between the protective cover 1 11 and the protective cover 2 13 to prevent the chain from swinging, so that the flying sparks and molten droplets are within the protection range of the protective cover 1 11 and the protective cover 2 13 to avoid splashing to the workers at other workstations, thereby improving the processing efficiency.

[0037] like Figure 1 and Figure 2 As shown, a connector 14 is fixedly connected to the inner wall of the second protective cover 13 , and a transparent plate 15 is plugged into the connector 14 . The transparent plate 15 is located at one side of the observation window 131 .

[0038] Specifically, the specific internal conditions can be observed through the observation window 131. The generated sparks and molten droplets will splash onto the inner walls of the protective cover 11, the protective cover 2 13 and the transparent plate 15. The transparent plate 15 can provide protection for the observation window 131, so that the internal conditions can be clearly observed. When the transparent plate 15 is contaminated, it is more convenient to replace than the observation window 131.

[0039] like Figure 2 As shown, the tops of the protective cover 11 and the protective cover 2 13 are fixedly connected to a fixed shaft 16 , the bottoms are fixedly connected to a base 18 , and the fixed shaft 16 is fixedly connected to a C-shaped ring 17 .

[0040] Specifically, the protective cover 1 11 and the protective cover 2 13 are closed to form a cylinder, the two C-shaped rings 17 are closed to form a ring, and the two bases 18 are closed to form a funnel shape, which is narrow at the top and wide at the bottom. Each C-shaped ring 17 and base 18 is equipped with an anti-sway mechanism 20.

[0041] like Figure 3 As shown, both ends of the spline shaft 25 are rotatably connected with sliders 22, and the sliders 22 are connected with fixing frames 21. The two fixing frames 21 are respectively fixed on the inner walls of the C-shaped ring 17 and the base 18.

[0042] Specifically, through the cooperation between the spline shaft 25 and the clamping plate 27, the clamping plate 27 can not only move along the axial direction of the spline shaft 25, but also rotate along with the spline shaft 25, so as not to restrict the chain fixed therein from rising.

[0043] like Figure 3 As shown, sliding openings are provided on both sides corresponding to the fixed frame 21, and the sliding openings are fixedly connected with a sliding rod 23. The slider 22 is movably sleeved on the outer ring of the sliding rod 23 and abuts against the side wall of the sliding opening. A spring 24 is fixedly connected to one side of the slider 22, and one end of the spring 24 away from the slider 22 is fixedly connected to the side wall of the sliding opening.

[0044] Specifically, the spline shaft 25 is moved along the axial direction of the slide rod 23 through the slider 22, and the spline shaft 25 is pushed to move toward the middle chain through the force of spring 1 24, while the clamping plate 27 fixes the middle chain through spring 2 28, so that it can limit the deflection of chains of different specifications.

[0045] like Figure 1 and Figure 3 As shown, the outer side of the protective cover 11 is fixedly connected with an internal threaded sleeve 12, and the internal threaded sleeve 12 is transmission-connected with a lifting mechanism 30. The lifting mechanism 30 includes a lifting frame 31, and the inner side of the lifting frame 31 is fixedly connected with a motor 32. The output end of the motor 32 is fixedly connected with a threaded rod 33, and the end of the threaded rod 33 away from the motor 32 is rotatably connected to the side wall of the lifting frame 31, and the threaded rod 33 is threadedly connected to the internal threaded sleeve 12.

[0046] Specifically, when the motor 32 is started, the threaded rod 33 will be controlled to rotate together. Through the thread cooperation between the threaded rod 33 and the internal threaded sleeve 12, the protective cover 11 connected thereto and the structure connected thereto can be driven to rise and fall together, so as to adapt to workers of different heights.

[0047] like Figure 1 and Figure 4 As shown, a crossbeam frame 41 is fixedly connected to the outer side of the lifting frame 31, one end of the crossbeam frame 41 is fixedly connected to a column 40, one end of the column 40 away from the crossbeam frame 41 is fixedly connected to a fixing seat 42, and the fixing seat 42 is rotatably connected to a turntable 43.

[0048] It should be noted that there are several beam frames 41 arranged in a circular array with the column 40 as the axis, and each beam frame 41 is a separate work station. The centers of the columns 40, the fixed seats 42 and the turntable 43 coincide with each other, and the fixed seats 42 can be rotated in the turntable 43 by a driving device, thereby achieving the purpose of automatically changing the work station.

[0049] like Figure 5 The crossbeam frame 41 is equipped with a traction mechanism 50, which includes a support frame 1 51, a motor 2 55 and a support frame 2 58. The support frame 1 51, the motor 2 55 and the support frame 2 58 are all fixed on the top of the crossbeam frame 41. The support frame 1 51 is rotatably connected to a transmission shaft 52, and a traction shaft 53 and a driven wheel 54 are fixedly installed on the outer ring of the transmission shaft 52. The output end of the motor 2 55 is fixedly connected to a driving wheel 56, and the driving wheel 56 and the driven wheel 54 are connected with a transmission chain 57. The support frame 2 58 is rotatably installed with an auxiliary pulley 59.

[0050] Specifically, when the motor 2 55 drives the driving wheel 56 to rotate, the transmission shaft 52 will be driven to rotate in the support frame 1 51 through the transmission chain 57 and the driven wheel 54, and the traction shaft 53 fixed on the transmission shaft 52 will be inserted into the hole of the chain ring, thereby driving the chain to move, making it convenient for the staff to process the chain rings at different positions.

[0051] The safety protection method of the chain continuous processing forming protection device comprises the following steps:

[0052] S1. Chain anti-sway:

[0053] The braided chain passes between the two bases 18 and the C-shaped ring 17, and the chain is raised by the traction mechanism 50. During this process, the two clamping plates 27 in each anti-sway mechanism 20 clamp and fix the chain link perpendicular to the spline shaft 25 in the chain through the force of the spring 28, so as to prevent the chain from swinging during welding or grinding, and avoid increasing the splash range of sparks and molten droplets due to the chain swing.

[0054] S2. Welding and grinding protection:

[0055] The staff holds a tool and extends it into the closed protective cover 11 and protective cover 2 13 from the operating port 132. The specific situation inside can be observed through the observation window 131. The sparks and molten droplets generated will splash onto the inner walls of the protective cover 11 and protective cover 2 13, and finally fall into the connection with the base 18. At the same time, the transparent plate 15 can provide protection for the observation window 131, so that the internal situation can be clearly observed.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
