Description

Technical Field

[0001] This application belongs to the field of gantry crane technology, specifically relating to a gantry crane track foreign object removal device and a gantry crane. Background Technology

[0002] Gantry cranes, also known as portal cranes, are widely used in industrial and mining enterprises and port cargo yards. Their metal structure resembles a portal frame, with two legs installed under the main load-bearing beam. The hubs on the two legs travel directly on rails on the ground.

[0003] Because gantry cranes are typically installed in open-air locations, their operation is greatly affected by on-site working conditions. In practice, small objects, oil, snow, frost, and other foreign matter often adhere to the rails. When the wheel hubs run over such foreign matter on the rails, the crane body may tilt, causing the wheels to deviate, resulting in "rail biting." Rail biting causes significant vibration throughout the crane, leading to loosening, breakage, and weld failure at connections such as the main beam, end beams, and rails, resulting in structural deformation. In severe cases, rail biting can even cause the crane to derail, leading to serious production safety accidents. Therefore, cleaning devices are usually used to remove foreign matter from the rails. However, with increased usage time and frequency, the distance between the cleaning plate and the rail gradually increases, affecting the effectiveness of removing foreign matter from the rails. Summary of the Invention

[0012] In some embodiments, the adjusting screw is threadedly connected to both the limiting member and the adjusting hole, and the limiting member is a nut.

[0013] In some embodiments, the first cleaning part is horizontally arranged, the angle between the first cleaning part and the second cleaning part is an obtuse angle, and the angle between the second cleaning part and the horizontal plane is 30° to 60°.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the embodiments of this application, such as Figure 1 and Figure 2As shown, a foreign object removal device 100 for a gantry crane track includes a connector 110, a removal component 120, and an adjustment assembly 130. The connector 110 is used to connect to the gantry crane 200; the removal component 120 is used to contact the track of the gantry crane 200; the adjustment assembly 130 includes an adjustment component 131 and a limiting component 132. One end of the adjustment component 131 is connected to the connector 110, and the other end of the adjustment component 131 is movably connected to the removal component 120 and set at an angle; or, one end of the adjustment component 131 is connected to the removal component 120 and set at an angle, and the other end of the adjustment component 131 is movably connected to the connector 110; the adjustment component 131 and the limiting component 132 are movably engaged to adjust the height of the removal component 120.

[0029] The connector 110 can be a connecting plate or a connecting rod. When the connector 110 is a connecting rod, the connecting rod is U-shaped, with both vertical sides used to connect to the gantry crane 200, and the horizontal side of the connecting rod movably connected to or fixedly connected to the adjusting member 131. In some embodiments, the connector 110 and the adjusting member 131 are set at an angle. In some embodiments, the connector 110 is set horizontally, and the adjusting member 131 is set vertically, so that the height of the clearing member 120 can be adjusted by the cooperation of the adjusting member 131 and the limiting member 132.

[0030] As the usage time and frequency increase, the cleaning component 120 will wear down during the process of removing foreign objects, and the vertical distance between the cleaning component 120 and the track will increase. Therefore, the height of the cleaning component 120 can be adjusted by adjusting the adjusting component 131 to ensure contact between the cleaning component 120 and the track, thereby removing foreign objects from the track.

[0031] In some embodiments, one end of the adjusting member 131 is connected to the connecting member 110, and the other end of the adjusting member 131 is movably connected to the first clearing part 121 and is set at an angle, that is, the other end of the adjusting member 131 can pass through the clearing part 120. Since the connecting member 110 is connected to the gantry crane 200, one end of the adjusting member 131 is fixedly connected, and the other end of the adjusting member 131 is movably connected. Therefore, by adjusting the adjusting member 131, the clearing part 120 can move relative to the connecting member 110, thereby adjusting the height of the clearing part 120. In other embodiments, one end of the adjusting member 131 is connected to the clearing member 120 at an angle, and the other end of the fixing member is movably connected to the connecting member 110. That is, one end of the adjusting member 131 is fixedly connected to the clearing member 120, and the other end of the adjusting member 131 can pass through the connecting member 110. Since the adjusting member 131 is connected to the clearing member 120, one end of the adjusting member 131 is fixed, and the other end of the adjusting member 131 is movable to the connecting member 110. The connecting member 110 is connected to the gantry crane 200 and cannot be moved. Therefore, by adjusting the adjusting member 131, the clearing member 120 can move relative to the connecting member 110, thereby adjusting the height of the clearing member 120.

[0032] Therefore, by adjusting the adjusting member 131, the cleaning member 120 can move relative to the connecting member 110, thereby adjusting the height of the cleaning member 120. This solves the problem that the distance between the cleaning member 120 and the track gradually increases due to wear and tear over a long period of use. In addition, the cleaning member 120 contacts the track of the gantry crane 200. During the movement of the gantry crane 200, foreign objects on the track are lifted up by the cleaning member 120 and pushed out of the track, thereby cleaning the foreign objects on the track.

[0033] In some embodiments, such as Figure 1 As shown, the cleaning component 120 includes a first cleaning part 121 and a second cleaning part 122. The second cleaning part 122 is bent toward the side away from the adjusting component 130, that is, the second cleaning part 122 is used to contact the track of the gantry crane 200. During the movement of the gantry crane 200, foreign objects on the track are lifted up by the second cleaning part 122 and pushed out of the track.

[0034] In some implementations, such as Figure 1 As shown, one end of the adjusting member 131 is connected to the first cleaning part 121 and is angled, while the other end of the adjusting member 131 is movably connected to the connecting member 110. In some embodiments, the first cleaning part 121 may be horizontally arranged, and the adjusting member 131 may be perpendicular to the first cleaning part 121, i.e., the adjusting member 131 is vertically arranged. Thus, the height of the cleaning member 120 can be adjusted by the cooperation of the adjusting member 131 and the limiting member 132.

[0035] In some embodiments, such as Figure 1 As shown, the connector 110 has an adjustment hole, and the fixing component includes an adjustment screw 1311 and a support 1312. The adjustment hole is a threaded hole, and the adjustment screw 1311 mates with the adjustment hole. One end of the adjustment screw 1311 is connected to the support 1312, and the other end of the adjustment screw 1311 extends into the adjustment hole and is connected to the limiting member 132. The support 1312 is connected to the first clearing part 121. In some embodiments, there are two adjustment holes, located at both ends of the connecting rod. When the connecting rod has a gate-shaped structure, the two adjustment holes are located on the horizontal side of the connecting rod. One side of the adjustment screw 1311 is fixedly connected to the support 1312. The adjustment screw 1311 and the support 1312 can be welded, glued, snapped together, etc., which are not limited in this application. It is easy to understand that the adjusting screw 1311 extends out of the connecting member 110. When the adjusting member 131 is rotated, the adjusting screw 1311 will move up and down along the adjusting hole relative to the connecting member 110, thereby changing the height of the cleaning member 120.

[0036] In some embodiments, such as Figure 1As shown, the adjusting screw 1311 is threadedly connected to the limiting member 132 and the adjusting hole, and the adjusting member 131 is a nut. By rotating the nut, the adjusting screw 1311 moves up and down along the adjusting hole relative to the connecting member 110, thereby changing the height of the cleaning member 120. After adjustment, rotating the adjusting nut causes it to abut against the connecting member 110, thus connecting and fixing the cleaning member 120 and the connecting member 110 via the adjusting assembly 130.

[0037] In some embodiments, the support member 1312 can be a support rod, and the support rod and the first cleaning part 121 can be connected by welding. In some embodiments, the support rod and the first cleaning part 121 are set at an angle, with the support rod set vertically and the first cleaning member 120 set horizontally.

[0038] In some embodiments, the first cleaning part 121 is horizontally arranged, the angle between the first cleaning part 121 and the second cleaning part 122 is an obtuse angle, and the angle between the second cleaning part 122 and the horizontal plane is 30° to 60°. It can be 30°, 35°, 40°, 45°, 50°, 52°, or 60°. The second cleaning part 122 is at a certain angle to the horizontal plane. During the movement of the gantry crane 200, foreign objects on the track are lifted and pushed off the track by the second cleaning part 122, thereby cleaning the foreign objects on the track.

[0039] In some embodiments, the first cleaning part 121 and the second cleaning part 122 are integrally formed, that is, the first cleaning part 121 and the second cleaning part 122 can be formed by bending a steel plate, which ensures the stability of the overall structure of the cleaning part 120.

[0040] In some embodiments, the second cleaning section 122 has a notch 123 at its center to match the track of the gantry crane 200. The length of the second cleaning section 122 matches the width of the track of the gantry crane 200, and the depth of the notch 123 matches the height of the track of the gantry crane 200. Since the track is mostly an I-beam steel structure, the notch 123 ensures that the second cleaning section 122 falls to the bottom along the upper surface of the I-beam steel, and then cleans the foreign objects on the track.

[0041] In some embodiments, since the track is mostly an I-beam steel structure, the top of the track is narrower than the bottom. Therefore, the width of the notch 123 gradually decreases from the side away from the connector 110 to the side closer to the connector 110, which can ensure that the second cleaning part 122 falls to the bottom along the upper surface of the I-beam steel and then cleans the foreign objects on the track.

[0042] In some embodiments, the notch 123 is trapezoidal in shape, and the depth of the notch 123 is smaller than the width of the second cleaning section 122. The notch 123 extends at least partially from the side away from the connector 110 to the side closer to the connector 110. Since the track is mostly an I-shaped steel structure, the plates on both sides of the notch 123 of the second cleaning section 122 can push up foreign objects on both sides of the track, and the plate above the notch 123 of the second cleaning section 122 can push up foreign objects at the top of the track.

[0043] The second aspect of this application, as Figure 2 As shown, a gantry crane 200 is provided, including a gantry crane body 210, traveling wheels 220, traveling wheel covers 221, and the aforementioned gantry crane track foreign object removal device 100. The traveling wheels 220 are disposed on the gantry crane body 210; the traveling wheel covers 221 are disposed on the traveling wheels 220 of the gantry crane 200; and the connecting member 110 is connected to the traveling wheel covers 221. During the movement of the gantry crane 200, foreign objects on the track are lifted and pushed out of the track by the second removal part 122, thereby clearing the foreign objects from the track.

[0044] In some embodiments, the connector 110 is detachably connected to the wheel cover 221, meaning that different specifications of cleaning components 120 can be installed according to the shape of the track, and then installed on the wheel cover 221 of the gantry crane 200 via the connector 110, thereby adapting to tracks of different sizes and specifications. Furthermore, the gantry crane track foreign object removal device 100 can be installed or not depending on the actual situation; for example, it can be installed when cleaning is needed, and removed from the gantry crane when cleaning is not required.

[0045] Through the above embodiments, this application has the following beneficial effects or advantages:

[0046] By adjusting the adjusting component 131, the cleaning component 120 can move relative to the connecting component 110, thereby adjusting the height of the cleaning component 120. This solves the problem that the distance between the cleaning component 120 and the track gradually increases due to wear and tear over a long period of use. In addition, the cleaning component 120 contacts the track of the gantry crane 200. During the movement of the gantry crane 200, foreign objects on the track are lifted up by the cleaning component 120 and pushed out of the track, thereby cleaning the foreign objects on the track.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
