Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a safety door locking device for steel cord stranding equipment. Background Art

[0002] Steel cord stranding equipment is used to combine multiple strands of steel cord into one strand. It plays a vital role in the steel cord production process. Currently, many old-style equipment do not have air pressure-controlled safety door locking devices, and the safety door poses a great hidden danger during the operation of the platform. Originally, the platform safety door fell backward by inertia and gravity after opening, but due to the micro-vibration caused by other mechanical equipment on the platform, the safety door that fell backward by gravity has a probability of covering forward, posing a great safety hazard. At the same time, when replacing the steel wire, the safety door often fell because it was not opened fully backward.

[0003] At present, if all the safety doors on the production line are converted to a pneumatic strut structure to lock the safety doors, the cost is very high. Therefore, faced with the problem that the safety doors cannot be locked, there is an urgent need for a low-cost and reliable device to convert all the safety door equipment on the production line. Utility Model Content

[0025] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0026] Combine Figure 1 As shown, the first aspect of the utility model proposes a safety door locking device for a steel cord stranding device, comprising a support seat 10, a positioning ring 20, a sliding shaft 30, a connecting rod 40 and a shift rod 50, wherein the support seat 10 and the positioning ring 20 are fixed to each other to form a first structural member, the sliding shaft 30, the connecting rod 40 and the shift rod 50 are fixed to each other to form a second structural member, the first structural member is connected to the outer wall of the device 100, the second structural member is installed to the first structural member, and can limit the covering of the equipment cover 200.

[0027] The equipment 100 refers to the steel cord stranding equipment, which includes an equipment box and an equipment cover 200. The box is provided with a stranding mechanism, a tension adjustment mechanism, etc. In order to simplify the equipment, Figure 1 The housing shown represents the device 100 .

[0028] Specifically, a first end of the support base 10 is connected to an outer wall of the device 100 , a second end of the support base 10 extends upward, and the positioning ring 20 is connected to the second end of the support base 10 .

[0029] Combine Figure 2 As shown, the support seat 10 is arranged in a Z shape, including a first vertical plate 11, a connecting horizontal plate and a second vertical plate 12. The first vertical plate 11 and the second vertical plate 12 are connected to both ends of the connecting horizontal plate, and the positioning ring 20 is connected to the upper end of the second vertical plate 12.

[0030] The first vertical plate 11 is provided with screw holes, which can be adapted to the outer wall of the device 100 and installed in a suitable position.

[0031] In this way, the second vertical plate 12 is further away from the outer wall of the device 100, so that the sliding shaft 30 can pass through the positioning ring 20 and extend outward for a distance without interfering with the normal opening and closing of the device cover 200, thereby preventing the sliding shaft 30 from easily falling off from the positioning ring 20.

[0032] Specifically, the sliding shaft 30 is slidably connected to the inner wall of the positioning ring 20 and can slide along the axial direction of the sliding shaft 30 and rotate around the axial direction. The first end of the connecting rod 40 is connected to the outer wall of the sliding shaft 30, and the gear rod 50 is connected to the second end of the connecting rod 40.

[0033] Among them, a notch 21 is provided on the surface of the positioning ring 20, and a positioning key 31 is provided on the outer wall of the sliding shaft 30. Preferably, the setting direction of the positioning key 31 is the same as the extension direction of the connecting rod 40, and the axis of the positioning key 31, the axis of the sliding shaft 30 and the axis of the gear lever 50 are in the same plane.

[0034] In this way, when the positioning key 31 is inserted into the notch 21, the sliding shaft 30 cannot rotate around its axis, and the shift lever 50 is at this time in the closing path of the device cover 200 to prevent the device cover 200 from closing, that is, the device cover 200 will not close out of control in a vibrating environment due to the blocking effect of the shift lever 50, and there will be no hidden danger of the device cover 200 closing automatically.

[0035] Furthermore, the axis of the positioning ring 20 is parallel to the rotation axis of the device cover 200 .

[0036] The maximum opening angle of the device cover 200 is defined as β, where β is between 90° and 120°, and the notch 21 is set between 90° and β.

[0037] In this way, when the positioning key 31 is inserted into the notch 21 of the positioning ring 20, the position of the lever 50 is also determined. Therefore, the setting position of the notch 21 determines the position of the lever 50. When the notch 21 is set between 90 and β, the lever 50 is also between 90 and β. Therefore, the device cover 200 with an opening angle of β can be limited to restrict its automatic closing.

[0038] Preferably, the width of the positioning key 31 is the same as the width of the notch 21. In this way, it can be ensured that after the positioning key 31 is inserted into the notch 21, no shaking occurs.

[0039] Optionally, the notch 21 may be a through groove that passes through the entire length of the positioning ring 20 , or a U-shaped groove that does not pass through completely.

[0040] Furthermore, a collar is provided at the bottom of the connecting rod 40 , and the collar is fixedly connected to the sliding shaft 30 via a positioning key 31 .

[0041] Specifically, a keyway is provided on the surface of the sliding shaft 30, and a keyway is also provided on the inner wall of the collar. When the positioning key 31 is inserted into the keyway, the right side of the collar is fixed by the step surface at the end of the sliding shaft 30, and the left side is fixed by the positioning key 31. Therefore, the collar and the sliding shaft 30 are fixed circumferentially and axially through the positioning key 31.

[0042] Preferably, the length of the lever 50 and the sliding shaft 30 are the same. The sliding shaft 30 is configured to include a first position and a second position, Figure 3 As shown, when the sliding shaft 30 is in the first position, the positioning key 31 is disengaged from the notch 21 , and the sliding shaft 30 and the shift lever 50 are outside the movement path range of the device cover 200 .

[0043] Combine Figure 4 As shown, when the sliding shaft 30 is in the second position, the positioning key 31 is engaged with the notch 21 , and the sliding shaft 30 and the shift lever 50 are on the movement path of the device cover 200 .

[0044] In combination with the above embodiments, the utility model proposes that the safety door locking device mainly includes two relatively movable structural parts. The support seat and the positioning ring are the first structural parts that can be adapted to the outer wall of the equipment. The sliding shaft, the connecting rod and the gear lever are the second structural parts that cooperate with the first structural part. The sliding shaft and the positioning ring slide to change the gear lever's relative position. The circumferential limitation of the sliding shaft is achieved by the positioning key, so that the gear lever is fixed in a preset position, preventing the equipment cover from closing automatically. The modification cost of this locking device is low, the adaptability is good, and it can effectively avoid the safety hazard of automatic closing of the equipment cover.

[0045] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
