Description

Technical Field

[0001] The utility model relates to the technical field of windproof anchoring devices, in particular to a windproof anchoring device for a door machine. Background Art

[0002] At present, gantry cranes (hereinafter referred to as "gantry cranes") are the main production equipment for loading and unloading cargo at the front line of ports. Windproof anchor limiters are the most common protective devices for gantry crane windproof anchoring devices, and play a vital role in ensuring the windproof safety of gantry cranes. However, the existing windproof anchor limiters are mechanical limiters, which are prone to wear or damage during operation. When they are worn to a certain extent, phenomena such as loosening of fixing pins, rusting of internal parts, and damage to rocker arms may occur. When the mechanical limiter fails, it will be manually used in urgent operations. If the limiter is forgotten to be restored over time, it will remain in an invalid state, and it is very easy to cause the anchor plate to tear during operation.

[0003] For this reason, personnel need to conduct regular inspections and adjust the mechanical limits frequently. In serious cases, the equipment must be scrapped and replaced with new ones to ensure the normal use of the equipment. This will increase the labor intensity of the staff. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] Combine Figures 1-8 The utility model provides a windproof anchoring device for a door machine, comprising a bracket 1, two sets of fixing plates 11 symmetrically provided on one side of the bracket 1, an anchoring plate 2 slidingly provided on the outer side of the fixing plate 11, and a driving component 3 for driving the anchoring plate 2 to move provided between the two sets of fixing plates 11;

[0028] A limit sensor 4 is provided on one side of the bracket 1 , and the limit sensor 4 is electrically connected to an intermediate relay 5 , and the intermediate relay 5 is electrically connected to a PLC 6 .

[0029] Specifically, first, the bracket 1 is welded to the appropriate position at the lower end of the door machine, and the bottom surface of the bracket 1 is in conflict with the door machine track. When the door machine needs to be windproof, the door machine is first controlled to move to the appropriate position, and the driving component 3 drives the two sets of anchoring plates 2 to be inserted into the limit sockets opened on the ground (such as Figure 8 As shown), with the cooperation of the anchoring plate 2 and the limit socket on the ground, the door machine can achieve the effect of wind protection. When the wind protection is over, the door machine needs to be used, and the anchoring plate 2 is driven upward by the driving component 3 to separate it from the limit socket opened on the ground. When the anchoring plate 2 moves up to a certain position, it triggers the limit sensor 4, and the limit sensor 4 transmits the signal to the intermediate relay 5, and then transmits it to the PLC6 through the intermediate relay 5. The PLC6 transmits the signal to the display or workbench display screen to which it is connected, so that the staff can monitor whether the anchoring plate 2 is in the limit state in real time, without the need for the staff to patrol one by one, which effectively reduces labor.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Combine Figure 2 and Figure 3 、 Figure 5 and Figure 6 The driving assembly 3 includes a motor 31 provided at the upper end of the bracket 1 and a rotating shaft 32 rotatably connected between the two sets of fixed plates 11. The output shaft end of the motor 31 is provided with a first bevel gear 311, and the outer side of the rotating shaft 32 is provided with a second bevel gear 321. The first bevel gear 311 is meshed with the second bevel gear 321. The two ends of the rotating shaft 32 are fixedly connected to the rocker arm 33, and one end of the rocker arm 33 is movably connected to the connecting plate 34, and the connecting plate 34 is connected to the anchor plug plate 2.

[0032] In this embodiment, the first bevel gear 311 is driven to rotate by the motor 31, and the engagement of the first bevel gear 311 drives the second bevel gear 321 to rotate, and the second bevel gear 321 drives the rotating shaft 32 to rotate, so that the rotating shaft 32 drives the two sets of rocker arms 33 to rotate. Since the anchor plate 2 is slidingly connected to the fixed plate 11, and the rocker arm 33 is movably connected to the connecting plate 34, when the rocker arm 33 rotates, the anchor plate 2 moves downward along the outer side of the fixed plate 11, so that the anchor plate 2 can be inserted into the limiting hole on the ground, so that it can limit the door machine, thereby achieving a windproof effect. On the contrary, the two groups of anchor plates 2 move upward and separate from the limiting holes. At this time, the door machine can operate normally.

[0033] Combine Figure 4 A fixing frame 12 is fixed to the outer side of the fixing plate 11 , and the anchoring plate 2 slides through the fixing frame 12 .

[0034] In this embodiment, the fixing frame 12 is slidably connected to the anchoring plate 2 so that when the rocker arm 33 rotates, the anchoring plate 2 moves up and down along the inside of the fixing frame 12 to prevent the anchoring plate 2 from deflecting during movement.

[0035] Combine Figure 4 A through slot 13 is provided at the upper end of the bracket 1 , and the anchoring plate 2 is slidably connected to the through slot 13 .

[0036] In this embodiment, when the anchor plate 2 moves downward, the anchor plate 2 passes through the through slot 13 and is inserted into the limiting hole on the ground. When the anchor plate 2 moves upward and separates from the limiting hole on the ground, the bracket 1 can support the anchor plate 2.

[0037] Combine Figure 3 and Figure 4 A slide groove 14 is provided on one side of the fixed plate 11 , and a sliding plate 21 is fixed on one side of the anchoring plug plate 2 . One end of the sliding plate 21 is connected to a top plate 211 , and the sliding plate 21 is slidably connected to the slide groove 14 .

[0038] In this embodiment, when the anchoring plate 2 moves up and down, the anchoring plate 2 drives the sliding plate 21 to move up and down inside the chute 14, and drives the top plate 211 to move up and down. Figure 3 As shown: when the anchor plate 2 drives the top plate 211 to move upward, the top plate 211 triggers the limit sensor 4. Through the electrical connection between the limit sensor 4, the intermediate relay 5 and the PLC 6, the staff can observe through the display screen or the workbench display that the anchor plate 2 is in a separated state from the limit hole on the ground. Then, the door operator can operate normally to prevent the anchor plate 2 from being damaged by the staff operating the door operator when the anchor plate 2 is inside the limit hole.

[0039] Combine Figure 2 An angle iron 15 is welded to one side of the bracket 1 , and the limit sensor 4 is mounted on the angle iron 15 .

[0040] In this embodiment, the angle iron 15 is welded to one side of the bracket 1 and the limit sensor 4 is mounted on the angle iron 15 to ensure the stability of the limit sensor 4 during use.

[0041] Combine Figure 2 , the limit sensor 4 is located between the two sets of fixed plates 11.

[0042] In this embodiment, since the limit sensor 4 is located between the two groups of fixed plates 11, the two groups of fixed plates 11 can provide a certain degree of protection for the limit sensor 4. When encountering strong winds, the limit sensor 4 can be blocked to prevent the strong wind from directly impacting the limit sensor 4 and causing damage, thereby further improving its service life.

[0043] It should be noted that the original limit voltage is provided by PLC6, which is 24V. Since the communication line from the limit sensor 4 to PLC6 is long, the voltage is greatly damaged. After the limit is replaced, the action is interrupted and cannot be executed accurately. However, this application adds an intermediate relay 5 between the limit sensor 4 and PLC6, so that the transmission signal can be amplified, and at the same time, the limit sensor 4 and PLC6 can be electrically isolated to avoid interference or misoperation caused by electrical interference, noise, etc., effectively improving the stability and reliability of the system. At the same time, when the limit sensor 4 fails, the intermediate relay 5 can send a feedback signal to PLC6 in time so that PLC6 can take corresponding measures, such as stopping the door machine operation, to avoid safety problems or equipment damage.
