Description

Technical Field

[0001] The present invention relates to the technical field of gantry crane accessories, and more particularly to an automatic iron shoe for a gantry crane. Background Art

[0002] As is known, the main structure of the gantry crane, which is mainly used for outdoor large-scale cargo loading and unloading operations, is similar to a door-shaped frame. Since two supporting legs are installed under its load-bearing main beam, and the bottom of the supporting legs are equipped with running wheels that can run on corresponding tracks, the gantry crane has the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. Therefore, the gantry crane has been widely used in port cargo yards.

[0003] However, since port cargo yards are all open areas, when wind blows, the wind force in these places is correspondingly stronger, and the relatively high body of the gantry crane is easily affected by the wind, causing its running wheels to slide along the track, thereby affecting the stability of the gantry crane; at present, in order to prevent the gantry crane from remaining stable in strong winds, it is often necessary to use iron shoes to position the running wheels of the gantry crane. The iron shoes currently used can only be manually added to the running wheels of the gantry crane by relevant personnel, and the positioning effect is poor and the operation is troublesome. Therefore, it is necessary to invent an automatic iron shoe for the gantry crane. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an automatic iron shoe for a gantry crane.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automatic iron shoe for a gantry crane, comprising a turntable, a support plate provided on the front side of the turntable, a forward and reverse motor provided on the inner surface of the support plate, a transmission shaft provided on the output end of the forward and reverse motor, and a transmission shaft connected to the forward and reverse motor; connecting rods are provided on both side surfaces of the turntable, the two connecting rods are arranged at different heights and have side panels on the outside, a seat body is provided at the bottom of the side panel, a shoe body is provided at the bottom of the seat body, a connecting plate is provided between the seat body and the shoe body, a fixing rod is fixed on the outer surface of the turntable, and an external plate is provided between the connecting rod and the fixing rod.

[0006] In a preferred embodiment, a connection hole is provided on the front surface of the turntable, and the connection hole is threadedly connected to the transmission shaft.

[0007] In a preferred embodiment, a mounting plate is fixedly provided on the bottom of the support plate, and the mounting plate is arranged on the bottom of the turntable.

[0008] In a preferred embodiment, the number of side panels is set to two and a connecting shaft is provided between the two side panels, a threaded hole is provided inside the connecting shaft, the connecting rod is threadedly connected to the threaded hole, and a positioning bolt is provided on the outer surface of the side panel, the number of the positioning bolts is set to two and passes through the side panels and is threadedly connected to the connecting shaft and the seat body respectively.

[0009] In a preferred embodiment, the number of the base bodies is set to two, and a fixing plate is fixed on the inner side thereof, a mounting seat is welded between the two fixing plates, and the shoe body is welded to the mounting seat.

[0010] In a preferred embodiment, the connecting plate is configured to be arc-shaped, and running wheels are evenly arranged on the bottom of the shoe body.

[0011] In a preferred embodiment, the top and bottom ends of the inner side of the external board are both provided with limiting plates, the limiting plates are provided with insertion holes inside, and the insertion board is inserted into the insertion holes.

[0012] The technical effects and advantages of the present invention are as follows:

[0013] 1. The present invention is provided with a forward and reverse motor, a connecting shaft and a shoe body. When the forward and reverse motor works, it can be driven to rotate by the transmission shaft, and the connecting shaft on the rotating surface will also move in height accordingly. When the forward and reverse motor works clockwise, the shoe bodies at the bottom of the two connecting rods will move inward accordingly, so that the wheels of the gantry crane can be clamped from the front and rear sides, thereby preventing the gantry crane from moving under external interference. When the forward and reverse motor works counterclockwise, the shoe bodies at the bottom of the two connecting rods will move outward accordingly, so that the shoe bodies leave the wheels of the gantry crane, and the gantry crane can move normally. The work of the forward and reverse motors can be quickly adjusted according to needs to limit the position of the gantry crane. The operation is simple and convenient, and the front and rear wheels of the gantry crane are respectively positioned by the front and rear sides, which plays a role in stable positioning.

[0014] 2. By providing side panels and external panels, the side panels are used to connect and fix the position of the connecting rod and the base body to ensure that the shoe body at the bottom can move stably. When the equipment is not in use, the limit plates on the inside of the external panels can be used to clamp the fixing rod and the connecting rod respectively, and position them through the plug-in plates. The overall positioning can then be done manually. The double positioning ensures that the gantry crane will not move. BRIEF DESCRIPTION OF THE DRAWINGS
