Description

Technical Field

[0001] This utility model belongs to the field of lock miter gate opening and closing technology, specifically relating to a wire guide device for a lock miter gate opening gauge. Background Technology

[0002] The operation of the miter gate in a ship lock starts at a low speed, gradually increasing to high speed based on changes in the stroke value, then gradually decreasing to low speed until it stops. The normal operation of the miter gate is highly dependent on the stroke value provided by the opening device. The existing opening device is an externally mounted pull-rope type, located inside the miter gate's operating room. A steel wire rope is led out from the opening device and its end is secured to the miter gate. During the closing process, the opening device's steel wire rope is pulled outwards, increasing the opening value. Conversely, the internal spring of the opening device tightens, retracting the steel wire rope and decreasing the opening value. During operation, the opening device's steel wire rope will sag due to its own weight, especially noticeable when the opening value is large. After sag, the steel wire rope contacts the metal edge of the opening device's outlet. As the miter gate reciprocates, the steel wire rope repeatedly rubs against the metal edge of the opening device's outlet until the steel wire rope breaks, causing the opening device to fail. Therefore, it is necessary to design a wire rope guide device for the lock miter gate opening gauge to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a wire rope guiding device for the opening gauge of a lock miter gate. It aims to solve the problem that in the prior art, the wire rope of the opening gauge will fall due to its own weight during the closing process of the miter gate, and when the miter gate is running back and forth, the wire rope of the opening gauge will repeatedly rub against the metal edge of the wire outlet of the opening gauge until the wire rope breaks and the opening gauge fails. It has the characteristics of simple structure, convenient use, effective support for the opening gauge wire rope, reducing its friction and protecting it from breakage.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a wire rope guiding device for a miter gate opening instrument of a ship lock, including a main fixing frame. One end of the main fixing frame has a semi-circular arc surface structure, and a steel clamp is fitted on the outer surface of the main fixing frame. The steel clamp fixes the main fixing frame to the wire outlet of the miter gate opening instrument. The bottom of the other end of the main fixing frame has a U-shaped ear plate, and a V-shaped roller is rotatably connected between the ear plates.

[0005] Preferably, the wire outlet of the herringbone gate opening gauge is a cylindrical structure, and the semi-circular arc surface structure of the main fixing frame has the same curvature as the outer surface of the cylindrical structure.

[0006] Preferably, the ear plate has U-shaped grooves on both sides, and the V-shaped rollers are sleeved on the outer surface of the main shaft. The two ends of the main shaft are connected to the U-shaped grooves by stop bolts.

[0007] Preferably, a bearing is installed in the opening at the center of the V-shaped roller, and the bearing is sleeved on the outer surface of the main shaft through a bushing. Preferably, the length of the bushing is shorter than the length of the main shaft.

[0008] Preferably, the main shaft has internal threaded through holes at both ends to cooperate with the stop bolts, and the diameter of the stop washer is larger than the inner diameter of the U-shaped groove.

[0009] Preferably, a level is connected to the bottom of the U-shaped ear plate.

[0010] Furthermore, the left end of the main body fixing frame is semi-circular, which increases the contact area between the steel clamp of the left end fixing component and the cylindrical wire outlet of the opening instrument, thereby restricting the horizontal movement and axial rotation of the main body component.

[0011] Furthermore, the main body fixing frame has a circular hole in the middle, which transitions and fits with the cylindrical wire outlet of the opening instrument, thereby ensuring the overall alignment accuracy.

[0012] Furthermore, the right end of the main body fixing frame is flat, with U-shaped grooves on both sides, which facilitates the installation of the main shaft from the top. At the same time, the main shaft can be finely adjusted vertically within the U-shaped groove, so that the opening gauge wire falls into the V-shaped groove of the V-shaped roller.

[0013] Preferably, the roller component is a V-shaped roller with bearings. The bearings make its rotation smooth, and the V-shaped roller grooves make it easy for the opening gauge wire to fall into its V-shaped bottom end, thereby preventing the opening gauge wire from sagging.

[0014] Furthermore, the bearing inner hole of the roller component can be limited by the main shaft and bushing, which is convenient to install and precise in positioning. During use, the position of the bushing can be adjusted left and right on the main shaft according to the orientation of the wire rope outlet hole of the opening instrument after assembly, so as to complete the fine adjustment in the horizontal direction and make the wire rope and the groove of the V-shaped roller collinear.

[0015] Furthermore, the outer diameter of the bushing of the limiting component is consistent with the inner diameter of the U-shaped groove.

[0016] Furthermore, the length of the main shaft of the limiting component is slightly shorter than the distance between the outer surfaces of the two flat structures on the right end of the main body fixing frame, so that when the main shaft is fixed by the fixing component, the fixing component can generate a greater preload, thereby fixing the main shaft better.

[0017] Furthermore, the fixing component uses steel clamps to fix the left end of the main body fixing frame. The main body fixing frame can be fixed by adjusting its tightness, while avoiding excessive squeezing and damage to the cylindrical wire outlet of the opening instrument; at the same time, it is easy to disassemble and install without damaging the original structure of the wire outlet.

[0018] Furthermore, the level indicator adjusts the level of the mechanism by reading its level value.

[0019] The beneficial effects of this device are: This externally mounted opening gauge wire guide device for the miter gate uses guide rollers installed at the wire outlet of the externally mounted opening gauge to support the opening gauge wire rope, which sags under its own weight. This prevents friction between the wire rope and the wire outlet, completely eliminating the risk of breakage caused by friction and thus eliminating the risk of opening gauge failure, thereby improving the inherent safety of lock operation. The device is compact and simple in structure, allowing for quick assembly and disassembly without affecting the efficiency of the opening gauge's assembly and disassembly, its daily operation and maintenance, or placing excessive weight on it. Simultaneously, the level monitoring component monitors its levelness, facilitating regular maintenance and adjustment. Attached Figure Description

[0021] Example 1: like Figures 1-5 As shown, a wire rope guiding device for a miter gate opening gauge of a ship lock includes a main fixing frame 1. One end of the main fixing frame 1 has a semi-circular arc surface structure, and a steel clamp 2 is fitted on the outer surface of the main fixing frame 1. The steel clamp 2 fixes the main fixing frame 1 to the wire outlet of the miter gate opening gauge. The bottom of the other end of the main fixing frame 1 has a U-shaped ear plate, and a V-shaped roller 3 is rotatably connected between the ear plates.

[0022] Preferably, the wire outlet of the herringbone gate opening gauge is a cylindrical structure, and the semi-circular arc surface structure of the main fixing frame 1 has the same curvature as the outer surface of the cylindrical structure.

[0023] Preferably, the ear plate has U-shaped grooves on both sides, the V-shaped roller 3 is sleeved on the outer surface of the main shaft 7, and the two ends of the main shaft 7 are connected to the U-shaped grooves by stop bolts 5.

[0024] Preferably, a bearing is installed in the opening at the center of the V-shaped roller 3, and the bearing is sleeved on the outer surface of the main shaft 7 through the bushing 8. Preferably, the length of the bushing 8 is shorter than the length of the main shaft 7.

[0025] Preferably, the main shaft 7 has internal threaded through holes at both ends to cooperate with the stop bolts 5, and the diameter of the stop washer 10 is larger than the inner diameter of the U-shaped groove.

[0026] Preferably, a level 4 is connected to the bottom of the ear plate of the U-shaped structure.

[0027] Furthermore, the left end of the main body fixing frame 1 is semi-circular, which increases the contact area between the steel clamp 2 of the left end fixing component and the cylindrical wire outlet of the opening instrument, thereby restricting the horizontal movement and axial rotation of the main body component.

[0028] Furthermore, the main body fixing frame 1 has a circular hole in the middle, which transitions and fits with the cylindrical wire outlet of the opening instrument, thereby ensuring the overall alignment accuracy.

[0029] Furthermore, the right end of the main body fixing frame 1 is flat, with U-shaped grooves on both sides, which facilitates the installation of the main shaft 7 from the top. At the same time, the main shaft 7 can be finely adjusted vertically within the U-shaped groove, so that the opening gauge wire falls into the V-shaped groove of the V-shaped roller 3.

[0030] Preferably, the roller component is a V-shaped roller 3 with bearings. The bearings make its rotation smooth, and the groove of the V-shaped roller 3 makes it easy for the opening gauge wire to fall into its V-shaped bottom end, thereby preventing the opening gauge wire from sagging.

[0031] Furthermore, the bearing inner hole of the roller component can be limited by the main shaft 7 and the bushing 8, which is convenient to install and precise in positioning. When in use, the position of the bushing 8 can be adjusted left and right on the main shaft 7 according to the orientation of the wire outlet hole of the opening instrument after assembly, so as to complete the fine adjustment in the horizontal direction and make the wire rope collinear with the groove of the V-shaped roller 3.

[0032] Furthermore, the outer diameter of the limiting component bushing 8 is consistent with the inner diameter of the U-shaped groove.

[0033] Furthermore, the length of the limiting component spindle 7 is slightly shorter than the distance between the outer surfaces of the two flat plate structures on the right end of the main body fixing frame 1, so that when the spindle 7 is fixed by the fixing component, the fixing component can generate a greater preload, thereby fixing the spindle 7 better.

[0034] Furthermore, the fixing component uses a steel clamp 2 to fix the left end of the main body fixing frame 1. The main body fixing frame 1 can be fixed by adjusting its tightness, while avoiding excessive squeezing and damage to the cylindrical wire outlet of the opening instrument; at the same time, it is easy to disassemble and install without damaging the original structure of the wire outlet.

[0035] Furthermore, the level 4 adjusts the level of the mechanism by reading its level value.

[0036] Example 2: The operating principle of this device is as follows: In use, this device needs to be installed at the wire outlet of the external gauge of the lock cylinder. The steel clamp 2 is fastened to the left side of the main body fixing frame 1 of the wire feeding guide device to fix the main body fixing frame 1 of the wire feeding guide device and the cylindrical wire outlet of the external gauge. The semi-circular design on the left side of the main body fixing frame 1 of the wire feeding guide device allows for greater friction between the steel clamp 2 and the cylindrical wire outlet of the external gauge, thereby limiting the horizontal movement and rotation of the main body fixing frame 1 of the wire feeding guide device. The right end of the main body fixing frame 1 has U-shaped grooves on both the inner and outer sides for installing the main shaft 7, and the height of the main shaft 7 can be finely adjusted in the vertical direction. The bearing V-shaped roller 3 is positioned by the bushing 8 so that the bottom of its V-shaped groove coincides with the center of the wire outlet of the external gauge. The bearing V-shaped roller 3 is installed together with the main shaft 7, bushing 8 and bearing. After adjusting the height, the locking bolt 5 is passed through the locking washer 10 for installation. The length of the main shaft 7 is slightly shorter than the distance between the outer ends of the double-sided U-shaped groove, which allows the stop bolt to obtain a greater preload. Tightening the stop bolt limits the position of the main shaft 7 and the bearing-loaded V-roller 3. The level 4 is installed on the left outer end of the main body fixing frame 1 of the wire feeding guide device, which facilitates observation and adjustment of the main body fixing frame 1 to ensure it is in a horizontal state. During operation, the steel wire at the wire outlet of the external level gauge of the lock horizontal cylinder drives the bearing-loaded V-roller 3 to rotate on the bearing, thereby preventing the wire from sagging and avoiding direct contact with the rigid structure of the wire outlet to prevent wear.
