Description

Technical Field

[0001] The invention relates to a fixing device, in particular to an auxiliary automatic fixing device for an outdoor door hanger. Background Art

[0002] Outdoor gantry cranes, also known as gantry cranes, are mainly used for material loading and unloading in outdoor places such as ports, docks, and construction sites. When an outdoor gantry crane is not in use, it is generally fixed with a track clamp to prevent the gantry crane from shifting due to strong winds. Typhoons often occur in coastal areas. In order to prevent the track clamp from being damaged and failing, temporary reinforcement methods such as steel wire rope tying wheels and fixed piles, wheels and inclined pads are often used to fix the gantry crane to prevent the track clamp from being damaged due to the movement of the gantry crane during a typhoon. However, the steel wire rope tying method has problems such as large movement and displacement, and the reliability of the inclined pad is low, making it difficult to achieve the expected fixing effect.

[0003] CN202967916U discloses a gantry crane fixing device, which comprises a gantry crane body, wherein a pulley (2) is arranged at the bottom of a supporting foot (1) of the gantry crane body, and the pulley (2) is arranged in a longitudinally arranged track (3), and is characterized in that a longitudinally arranged cable trough (4) is arranged on the ground outside the track (3), a longitudinally arranged guardrail (5) is arranged on the ground outside the cable trough (4), and a fixing seat (6) is arranged on the ground outside the guardrail (5), and the fixing seat (6) and the supporting foot (1) are fixedly connected by a chain (7). The fixing seat (6) and the supporting foot (1) of the fixing device are fixedly connected by a chain, so that the supporting foot of the gantry crane will not slip in a non-working state, and misalignment between the supporting foot and the track is avoided. However, the fixing device only solves the most basic anti-slip problem of the gantry crane in a non-working state, and the fixing effect of the chain structure is limited, and it is difficult to resist the slip problem of the gantry crane caused by typhoons.

[0019] In this embodiment, the trigger mechanism includes a trigger spring 51 and a touch ball 52. The side of the sliding plate 3 facing the door hanger is rigidly connected with a sliding sleeve 53, and the sliding sleeve 53 is inserted into the sliding plate 3. The trigger spring 51 is vertically fixed on the sliding sleeve 53, and the touch ball 52 is fixed on the top of the trigger spring 51. The fixed lock buckle 2 is provided with a receiving groove 22 adapted to the touch ball 52. A positioning spring 61 in a compressed state is connected between the side of the sliding plate 3 away from the door hanger and the fixed rod 4. The positioning spring 61 is sleeved on the outside of a circular shaft 62, one end of the circular shaft 62 is fixed on the fixed rod 4, and the other end of the circular shaft 62 is freely inserted into the sliding sleeve 53. The circular shaft 62 is coaxially arranged with the sliding sleeve 53, and the axial direction of the circular shaft 62 is parallel to the sliding direction of the sliding plate 3. When the fixed lock buckle 2 contacts the touch ball 52, the trigger mechanism is triggered.

[0020] In this embodiment, a limiting column 44 is rigidly connected to the fixing rod 4, and the limiting column 44 is used to position the automatic lock 1 after the door hanger is fixed; the limiting block 31 is inclined from top to bottom toward the lower side of the automatic lock 1, and the locking end 12 is inclined from bottom to top toward the sliding plate 3.

[0021] In this embodiment, the fixed rod 4 includes a first upright portion 41, a horizontal portion 43 and a second upright portion 42 that are integrally arranged, the sliding plate 3 is slidably connected to the fixed rod 4, the first upright portion 41 is rotationally connected to the automatic lock 1 through a rotating shaft 16, the limiting column 44 is rigidly connected to one side of the first upright portion 41, one end of the circular shaft 62 is fixed to the fixed rod 4, and the two ends of the positioning spring 61 are respectively fixed to the sliding plate 3 and the second upright portion 42.

[0022] In this embodiment, the automatic lock 1, the limit block 31, the sliding plate 3, and the fixing rod 4 are respectively made of δ30mm steel, the handle 13, the rotating shaft, the round shaft 62, the limit column 44, and the fixing pin 15 are respectively made of Φ10mm round steel, the sliding sleeve 53 is made of a Φ12*2.5 sleeve, the positioning spring 61 is made of a thin spring, the trigger spring 51 is made of a thick spring, and the touch ball 52 is made of a steel ball matching the trigger spring 51.

[0023] After the above-mentioned outdoor door hanger auxiliary automatic fixing device is installed, before the door hanger is fixed, the locking end 12 is limited by the limit block 31, the lower surface of the limit block 31 contacts the upper surface of the locking end 12, and the lock end 11 is lifted. The state at this time is as shown in the figure Figure 1 and Figure 2 As shown; the door hanger drives the fixed lock catch 2 to move until the trigger mechanism is triggered, and the fixed lock catch 2 pushes the sliding plate 3 to move away from the door hanger. When the locking end 12 disengages from the limit block 31, the automatic lock catch 1 automatically rotates under the action of its own weight until the lock catch end 11 is turned into the lock hole 21, thereby realizing auxiliary fixation of the door hanger. At the same time, the trigger spring 51 is deformed, and when the touch ball 52 enters the accommodating groove 22, the trigger spring 51 is reset, and the sliding plate 3 is reset to the upper surface of the limit block 31 and the lower surface of the locking end 12 under the action of the positioning spring 61. At this time, the automatic lock catch 1 is limited by the limit block 31 and the limit column 44, and the door hanger is locked. At this time, the fixing pin 15 can also be inserted into the pin hole 14 at the bottom end of the lock catch end 11 to further strengthen the locking effect. When the door hanger needs to be unlocked, the fixing pin 15 is removed, and the handle 13 is directly pulled up to lift the lock end 11. The automatic lock 1 rotates and pushes the sliding plate 3 away from the door hanger through the locking end 12. The sliding plate 3 drives the trigger spring 51 and the touch ball 52 to move, so that the touch ball 52 moves out of the accommodating groove 22 until the sliding plate 3 is reset to the lower surface of the limit block 31 under the action of the positioning spring 61 to contact the upper surface of the locking end 12. At this time, the door hanger can move directly. The state at this time is shown in the figure as follows Figure 3 and Figure 4 shown.

[0024] The above-mentioned outdoor door crane auxiliary automatic fixing device uses the kinetic energy and position of the door crane's own operation to trigger the device, uses the deadweight of the automatic lock 1 to lock the suspended door, and uses the rebound function of the trigger spring 51 and the positioning spring 61 to ensure the reliability of repeated triggering, thereby realizing the positioning of the automatic lock 1 in different states and ensuring the functional reliability of the device.
