Technical Field

[0001] This utility model belongs to the field of overhead crane equipment technology, and in particular relates to a simple outdoor overhead crane windproof wedge block device. Background Technology

[0002] Overhead cranes, also known as bridge cranes or gantry cranes, are the most widely used type of lifting machinery. With the rapid development of the national economy, overhead cranes have become indispensable equipment in many manufacturing industries and are widely used in outdoor material lifting and short-distance transportation operations. During daily outdoor operations, overhead cranes often encounter extreme weather conditions such as strong winds. Under such conditions, the overhead crane cannot rely solely on its own braking system to prevent it from sliding along the track; additional external force is needed to prevent the crane from sliding along the track, ensuring the safety of the crane, workers, and the work site.

[0003] Therefore, it is necessary to develop an outdoor overhead crane windproof wedge block device that is simple to manufacture, has lightweight components, is easy to install and disassemble, has low cost, and has good windproof effect. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 5As shown, a simple outdoor crane windproof wedge device includes two wedge structures 1, a first pull rod 2, a connecting nut 3, a second pull rod 4, and two locking nuts 5. The wedge structure 1 includes a wedge 101 and guide plates 102. The guide plates 102 are welded to both sides of the wedge 101. The groove formed by the two guide plates 102 and the wedge 101 mates with the crane track 30. The wedge 101 is an isosceles right-angled triangle. In this embodiment, the bottom surface of the wedge 101 is perpendicular to the rear end surface, the length of the bottom surface is greater than the height of the rear end surface, and the width of the bottom surface, the width of the rear end surface, and the width of the crane track are the same. A threaded hole is machined at the center of the rear end surface of the wedge 101. One end of the first pull rod 2 is threadedly connected to one wedge 101 through the threaded hole. One end is threaded to the connecting nut 3; one end of the second pull rod 4 is threaded to another wedge 101 through a threaded hole, and the other end is threaded to the connecting nut 3; a locking nut 5 is installed at the connection between the first pull rod and the corresponding wedge 101, and at the connection between the second pull rod and the corresponding wedge 101. The locking nut is used to prevent the threads at the connection between the pull rod and the wedge 101 from loosening when the connecting nut 3 is rotated; the threads of the first pull rod 2 and the second pull rod 4 connected to the connecting nut 3 have opposite directions at the connection, and rotating the connecting nut 3 makes the distance between the two wedges 101 longer or shorter.

[0022] Guide plates 101 are welded to both sides of the wedge 101, which can quickly and correctly place the wedge structure 1 onto the overhead crane track 30 and complete the installation quickly. The guide plates 101 also ensure that the wedge 101 does not deviate during the extension and retraction of the overhead crane track 30, thus improving the installation efficiency.

[0023] One end of pull rod 2 and pull rod 4 are respectively tightened to the threaded hole on the rear end face of the wedge 101 of the corresponding wedge structure 1. A locking nut 5 is provided between pull rod 2, pull rod 4 and the wedge of the corresponding wedge structure 1. The other ends of pull rod 2 and pull rod 4 are connected together by a connecting nut 3. During use, by rotating the connecting nut 3, the pull rod and wedge structure of the simple outdoor crane windproof wedge device 10 are driven to extend and retract along the crane track 30, thereby supporting the crane wheel 20 and making the wedge structure 1 fit tightly with the front and rear wheels of the crane and the crane track 30. When the crane shows any tendency to slide due to wind, the support of the wedge can firmly fix the crane on the crane track and prevent the outdoor crane from sliding under strong wind conditions.

[0024] In a preferred embodiment, the width of the wedge 101 is exactly the same as the width of the overhead crane track 30, ensuring that the inclined surface of the wedge 101 can be completely inserted into the groove of the overhead crane wheel 20, making the overhead crane wheel 20 more reliably fixed.

[0025] In a preferred embodiment, the threaded hole on the wedge 101 has a right-hand thread. To ensure that the two wedge structures 1 extend or retract simultaneously when the connecting nut 3 is rotated, both ends of the pull rod 2 have right-hand threads, one end of the pull rod 4 has a right-hand thread and the other end has a left-hand thread, one end of the inner hole of the connecting nut 3 has a right-hand thread and the other end has a left-hand thread, the right-hand thread of the pull rod 2 connects to the right-hand end of the connecting nut 3, and the left-hand thread of the pull rod 4 connects to the left-hand end of the connecting nut 3. The structure is flexible, simple, and easy to operate.

[0026] In a preferred embodiment, the connecting nut 3 has an external hexagonal structure, which facilitates rotation of the connecting nut using auxiliary equipment such as a wrench.

[0027] In addition, to increase the stress resistance of tie rod 12 and tie rod 24, the two tie rods in this embodiment are made of grade 8.8 strength.

[0028] The specific installation process of this utility model is as follows: Before installing the simple outdoor crane windproof wedge device 10, first rotate the connecting nut 3 to move the first pull rod 2 and the second pull rod 4 in opposite directions, retracting the simple outdoor crane windproof wedge device 10 to its shortest distance. Then, place the outdoor crane windproof wedge device 10 onto the crane track 30 between the two crane wheels 20. Then, use a wrench to rotate the connecting nut 3 in the opposite direction to extend the wedge structure 1 along the crane track 30 until the wedge 101 is tangentially pressed against the groove of the crane wheel 20. When disassembling the simple outdoor crane windproof wedge device 10, use a wrench to rotate the connecting nut 3 in the opposite direction to retract the first pull rod 2 and the second pull rod 4. The operation is flexible and convenient.

[0029] This invention connects two wedge structures 1 via two tie rods (tipping rod 1 2 and tie rod 2 4) and a connecting nut 3. The extension and retraction of the wedge structures 1 are adjusted by rotating the connecting nut 3. When the trolley tends to slide along either side of the trolley track 30 under wind force, the wedge structures 1 provide support, ensuring the balance of external forces exerted on the trolley by the wind. Furthermore, the wedges are in contact with the lowest point of the trolley wheel 20. When the trolley wheel slips slightly, the pressure on the wedges increases, increasing the friction between the wedges and the trolley track 30, further ensuring safety and preventing the trolley from sliding along the track. This device is economical and easy to manufacture. The simple outdoor crane windproof wedge device is reliable and effective, and can safely prevent the crane from sliding along the track.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
