[0002] Cranes are often blown away or slipped away during outdoor operations, which can easily cause accidents such as derailment or overturning. To prevent being blown away by the wind, windproof anchoring devices are generally installed. This device can be used to stabilize the equipment itself in strong winds and bad weather to prevent the gantry crane from being forced to move and tilt forward and backward, thereby improving the safety factor of the gantry crane in a free state and ensuring safe production.

The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.
[0041] Cranes are often blown away or slipped away during outdoor operations, which can easily cause accidents such as derailment or overturning. To prevent being blown away by the wind, windproof anchoring devices are generally installed. This device can be used to stabilize the equipment itself in strong winds and bad weather to prevent the gantry crane from being forced to move and tilt forward and backward, thereby improving the safety factor of the gantry crane in a free state and ensuring safe production.
[0042] In the relevant embodiments, a windproof iron wedge or a car stopper can be placed at the rail wheel, but the windproof iron wedge or the car stopper has no electrical interlocking protection, and it is easy to forget to remove it when operating the gantry crane, resulting in poor wind protection or even ineffectiveness; the rail clamp module can be tightened by manually rotating the steering wheel through the manual rotation of the rail clamp, but there is no electrical interlocking protection, and it is easy for the operator to operate the gantry crane without loosening it, resulting in cumbersome operation; and if a manual rail clamp is used, there is also the problem of cumbersome operation and poor effect.
[0043] To solve the problem that the windproof anchor device is cumbersome to operate and has poor windproof effect, see Figure 1-Figure 10 An embodiment of the present application provides a self-locking windproof ground anchor device for a gantry crane, comprising: an anchor bracket 1, an anchor shaft 3 and an anchor base 2.

One side of the anchor bracket 1 can be welded to the walking beam. Since Q345 steel has high strength and good welding performance, the material of the anchor bracket 1, the anchor shaft 3 and the anchor base 2 can be selected from Q345 steel. The gantry crane can be equipped with two sets of gantry crane self-locking windproof anchor devices, wherein the anchor base plate 21 can be four pieces, which are respectively arranged at both ends of the steel track.

[0047] The self-locking windproof ground anchor device of the gantry crane is fixedly connected to the gantry crane through the anchor bracket 1, and then uses the anchor shaft 3 as an anchor point to increase the supporting capacity to cope with wind force and improve the windproof effect; and the operator only needs to move the anchor shaft 3 to make the gantry crane work, thereby solving the problem of cumbersome operation and poor windproof effect of the windproof ground anchor device.
[0048] In some embodiments, a pull ring is provided on the top of the anchoring shaft 3, and the pull ring is an elliptical structure.
[0049] The pull ring with an elliptical structure can not only better disperse the force and reduce local pressure, but also reduce the risk of exposing sharp edges, thereby reducing damage when pulling.

[0051] See also Figure 4 and Figure 8 , the diameter of the first through hole and the second through hole can be 100 cm; the long axis of the third through hole and the fourth through hole can be 140 cm, and the short axis of the third through hole and the fourth through hole can be 102 cm. The anchoring shaft 3 of the cylindrical structure has a circular cross section, which is relatively strong and evenly distributes pressure when subjected to pressure, thereby having higher structural stability and bearing capacity.
[0052] In some embodiments, a stopper 31 is provided at the bottom of one side of the anchor shaft 3 close to the gantry crane, the third through hole and the fourth through hole are both elliptical structures, and the sum of the cross-sectional diameter of the anchor shaft 3 and the length of the stopper 31 is smaller than the major axis of the third through hole and the fourth through hole, and larger than the minor axis of the third through hole and the fourth through hole.
[0053] See also Figure 9-10 The size of the stopper 31 may be 20cm*40cm*55cm.
[0054] The anchor shaft 3 can be firmly locked by the stopper 31, the third through hole and the fourth through hole, thereby reducing the possibility of loosening of the self-locking windproof anchor device of the gantry crane.
[0055] In some embodiments, the first through hole and the second through hole are circular structures, and the first baffle plate 11 and the second baffle plate 13 are also provided with a first blocking hole and a second blocking hole, the first through hole is connected to the first blocking hole, and the second through hole is connected to the second blocking hole, and the first blocking hole and the second blocking hole are both arranged above one side of the long axis of the third through hole and the fourth through hole.
[0056] See also Figure 4 The width of the first blocking hole and the second blocking hole is 22 cm; the length of the first blocking hole and the second blocking hole is greater than 40 cm. The first blocking hole and the second blocking hole are used to pass through the block 31, so that the block 31 can smoothly enter the three through holes and the fourth through hole.
[0057] In some embodiments, a fifth through hole is further formed on the first baffle 11 , and the fifth through hole has the same size as the first through hole.
[0058] The fifth through hole is used to place the anchor shaft 3 when the gantry crane is required to work.
[0059] In some embodiments, the length of the first blocking hole is greater than that of the second blocking hole, and a side of the first blocking hole away from the first through hole is connected to the fifth through hole.
[0060] The first blocking hole is connected to the fifth through hole, which can not only be used to pass the blocking block 31 , but also reduce the number of blocking openings, thereby improving the strength of the first baffle 11 .
[0061] In some embodiments, the self-locking windproof ground anchor device of the gantry crane also includes a base plate and ground anchor bars; the base plate is pre-buried under the ground, and the bottom of the steel track of the gantry crane is fixedly connected to the base plate; the anchor base plate 21 is fixedly connected to the base plate and the ground anchor bars.
[0062] It should be understood that the anchor base plate 21 can be fixed by welding, and then can be pre-buried with concrete. The base plate and the ground anchor bar can not only further connect the gantry crane, but also increase the bearing capacity of the gantry crane and resist the invasion of wind.
[0063] In some embodiments, a base pit is opened on the base plate, and the anchoring base plate 21 is arranged inside the base pit.
[0064] The anchoring base plate 21 is arranged inside the base pit to improve the windproof effect.
