[0044] like Figure 1 and Figure 2 As shown, this utility model provides an automatic retraction bidirectional windproof device for wheel chocks, which is installed between the two wheels of a bridge crane and includes:

[0045] The first mounting base 1 is located at the bottom of the bridge crane's large balance beam, and the first mounting base 1 has a lifting mechanism mounting position;

[0046] A lifting mechanism is provided at the lifting mechanism mounting position, and the output end of the lifting mechanism is vertically downward.

[0049] And two windproof iron shoes 6, which are respectively set on the two output ends of the plug-and-retract mechanism.

[0050] The brake mechanism simultaneously drives two windproof iron shoes to move to the wheels under the bridge crane to achieve braking. The braking position can be adjusted by controlling the stroke of the brake mechanism, and the whole process is fast and accurate.

[0051] In one embodiment of the automatic retraction bidirectional windproof plug device provided by this utility model,

[0052] The front and rear sides of the second mounting base 4 are respectively provided with limiting sleeves 41 corresponding to the windproof iron shoe 6;

[0053] The windproof iron shoe 6 has a limiting pin 61 on the front and rear sides of its end to pass through the limiting sleeve 41, and the end of the limiting pin 61 is provided with a limiting nut 62.

[0054] The limiting sleeve makes it less likely for the mounting base and the windproof iron shoe to deviate, making the entire structure more stable.

[0055] In one embodiment of the automatic retraction bidirectional windproof iron shoe provided by this utility model, a cylindrical spring 7 is provided between the head end of the limiting sleeve 141 and the end of the windproof iron shoe 6, and the cylindrical spring can play a buffering role.

[0056] To improve overall accuracy and stability, in one embodiment of the automatic retraction bidirectional windproof plug device provided by this utility model,

[0057] There are two limiting sleeves 41, which are parallel to each other and arranged vertically.

[0058] The limiting pin 61, the cylindrical spring 7, and the limiting sleeve 41 are arranged in a one-to-one correspondence.

[0059] In one embodiment of the automatic retraction bidirectional windproof plug device provided by this utility model,

[0060] The windproof iron shoe 6 has a wedge-shaped head end, which can be fully inserted into the gap between the wheel and the track to achieve braking;

[0061] The bottom of the windproof iron shoe 6 has a rail locking part 63, which can make greater contact with the rail, making the whole structure more stable.

[0062] In one embodiment of the automatic retraction bidirectional windproof plug device provided by this utility model,

[0063] The lifting mechanism mounting position includes:

[0064] The limiting plate 21 is disposed below the first mounting base 1 and has four limiting holes at its four corners;

[0065] And four support rods 22, which are disposed between the limiting plate 21 and the first mounting base 1;

[0066] The lifting mechanism includes:

[0067] An electric hydraulic actuator 31 is fixed to the lower surface of the first mounting base 1, and the output end of the electric hydraulic actuator 31 is set vertically downward.

[0068] The fixing plate 32 is horizontally fixed to the output end of the electric hydraulic actuator 31;

[0069] Furthermore, the hinge rod 33 corresponds one-to-one with the support rod 22 and its middle section is hinged to the support rod 22;

[0070] Four hinge rods 33 are respectively hinged at the four corners of the fixed plate 32, and each hinge rod 33 corresponds to a support rod 22. The middle section of each hinge rod 33 is slidably connected to a cylindrical protrusion on the support rod 22 through a strip groove.

[0071] The upper end of the chain 35 is connected to the lower surface of the end of the hinge rod 33 by a hook and a hanging ring, and the lower end passes through the limiting hole and is fixed to the second mounting base 4.

[0072] A damping spring 34 is disposed between the upper surface of the end of the hinge link 33 and the lower surface of the first mounting base 1.

[0073] An electric hydraulic actuator drives the fixed plate to move up and down, which in turn moves the head end of the hinge rod up and down. This causes the end of the hinge rod to move the suspension chain up and down, ultimately raising and lowering the entire device to achieve automatic retraction. The hinge rod and support rod are movably connected via a strip-shaped groove and a cylindrical protrusion, without affecting the hinge rod's degrees of freedom.

[0074] In one embodiment of the automatic retraction bidirectional windproof plug device provided by this utility model,

[0076] Alternatively, the retracting mechanism 5 may be two hydraulic cylinders or pneumatic cylinders placed back to back.

[0077] This utility model provides an automatic retraction bidirectional stopper windproof device. When the trolley is running, the stopper automatically retracts and is automatically retracted by a hydraulic push rod. When the trolley stops running, the stopper automatically falls and is automatically placed under the wheel. The device has stopper retraction limit detection protection, as well as left and right limit detection protection. When the stopper is detected to be completely pressed by the wheel, the trolley operation will be stopped by an interlock.

[0078] This invention includes two actuators: one for automatically extending and retracting the bidirectional stopper, and the other for lifting and lowering the bidirectional stopper. This invention can quickly and completely insert the stopper into the bottom of both wheels to achieve a braking effect, completely replacing manual operation of the stopper action. If one set of this device is installed on each leg of the gantry crane, it is equivalent to inserting eight stoppers, completely replacing manual operation of inserting the stopper, greatly reducing the workload of dockworkers and improving the gantry crane's wind resistance.

[0079] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details.
