Description

Technical Field

[0001] This utility model relates to the field of rail clamps, and more particularly to rail clamps for unloading machines used for wind protection. Background Technology

[0002] Ship unloaders are specialized machines that utilize continuous conveying machinery to lift bulk materials, or have self-retrieving capabilities, or are equipped with material handling and feeding devices, to continuously lift bulk materials out of the ship's hold, unload them onto the boom or frame, and transport them to the main conveyor system on the shore.

[0003] As the ship unloader moves along the track, it is necessary to fix the ship unloader and the guide rail. Currently, rail clamps are usually used as fixing components.

[0004] However, since ship unloaders typically operate in windy environments such as ports, they are subject to significant crosswinds during operation. Ordinary rail clamps are not designed for crosswinds, meaning they rely solely on mechanical clamping to maintain stability. Since a certain gap generally exists between the guide wheels and guide rails to ensure their normal rotation, crosswinds can easily cause the guide wheels to deflect, resulting in significant wear on the rail clamps and guide rails, thus greatly impacting their lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a rail clamp for a ship unloader that improves the stability of the rail clamp in environments such as crosswinds.

[0006] To solve the above-mentioned technical problems, this utility model provides a rail clamp for a ship unloader used for wind protection, including a main wheel that is rolled on a guide rail, mounting seats placed on both sides of the main wheel, a main shaft that is connected to the main wheel and the two ends of the main shaft are rotatably engaged with the mounting seats, and the mounting seats are liftably connected to guide wheels, which are rotatably engaged with the sides of the guide rail.

[0007] Furthermore, a lifting groove is provided at the mounting base, the lifting shaft is movably installed in the lifting groove, and a number of guide grooves are provided at intervals along the circumference of the lifting groove. A number of guide blocks matching the guide grooves are arranged at intervals along the circumference of the lifting shaft, and the guide wheel is rotatably connected to the lifting shaft.

[0008] Furthermore, a driving component is provided at the mounting base, and an adjusting rod is connected to the output end of the driving component. An adjusting groove is provided inside the lifting shaft, and the adjusting rod is threadedly engaged with the adjusting groove.

[0009] Furthermore, guide grooves are provided on both sides of the guide rail, and the two sides of the guide grooves have a first arc surface, and the side of the guide wheel has a second arc surface that matches the first arc surface.

[0010] Furthermore, a guide bar is provided on the side of the guide rail facing the main wheel along the moving direction of the main wheel, and the main wheel is provided with a groove in the circumferential direction that matches the guide bar, so that when the main wheel rolls along the guide rail, the guide bar is engaged in the groove.

[0011] Furthermore, the lifting shaft end is provided with a first limiting ring and a second limiting ring, and the guide wheel is engaged between the first limiting ring and the second limiting ring.

[0012] Furthermore, the mounting base has a mounting plate at its end, and the mounting plate has several mounting holes on its side.

[0013] The beneficial effects of this utility model are as follows: the mounting base is connected to the bottom of the corresponding ship unloader, and the main wheel is mounted on the guide rail. At this time, the ship unloader can transport goods by moving the main wheel along the guide rail. At the same time, the guide wheels on both sides of the guide rail guide the movement direction of the main wheel. If there is a crosswind or other environmental conditions, the two guide wheels can be raised and lowered respectively, so that the two guide wheels are staggered and the guide wheel on the windward side of the rail clamp is on the upper side. In this way, while ensuring the guiding role of the guide wheel for the ship unloader, the staggered distribution of the two guide wheels increases the resistance of the guide wheel to tilting when affected by crosswinds, thereby improving the overall stability of the rail clamp.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] like Figures 1-4 The present invention provides a rail clamp for a ship unloader used for wind protection, including a main wheel 2 that is rolled on a guide rail 1, mounting seats 3 placed on both sides of the main wheel 2, a main shaft 4 that is connected to the main wheel 2 and the two ends of the main shaft 4 are rotatably engaged with the mounting seats 3, and the mounting seats 3 are liftably connected to guide wheels 5, the guide wheels 5 being rotatably engaged with the side of the guide rail 1.

[0023] Connect the mounting base to the bottom of the corresponding ship unloader and mount the main wheel on the guide rail. The ship unloader can then transport materials by moving the main wheel along the guide rail. At the same time, the guide wheels on both sides of the guide rail guide the movement direction of the main wheel. In the event of crosswinds, the two guide wheels can be raised and lowered respectively, so that the two guide wheels are staggered, with the guide wheel on the windward side of the rail clamp located on the upper side. This ensures that the guide wheels guide the ship unloader while increasing the resistance to tilting when affected by crosswinds, thereby improving the overall stability of the rail clamp.

[0024] Preferably, the mounting base 3 has a lifting groove 6, the lifting shaft 7 is movably installed in the lifting groove 6, and the lifting groove 6 has a plurality of guide grooves 8 spaced apart along the circumference, and the lifting shaft 7 has a plurality of guide blocks 9 spaced apart along the circumference that match the guide grooves 8, and the guide wheel 5 is rotatably connected to the lifting shaft 7.

[0025] Specifically, when controlling the guide wheel to rise and fall, the guide block moves along the guide groove to ensure the stability of the lifting shaft, thereby causing the lifting shaft to move along the lifting groove to drive the lifting operation of the guide wheel.

[0026] Preferably, a drive component 10 is provided at the mounting base 3, and an adjusting rod 11 is connected to the output end of the drive component 10. An adjusting groove 12 is provided inside the lifting shaft 7, and the adjusting rod 11 and the adjusting groove 12 are threaded together.

[0027] Specifically, the adjustment rod is rotated by a drive component. Since the adjustment rod and the adjustment groove are threaded together, and the lifting shaft can only move up and down relative to the mounting base, the rotation of the adjustment rod can control the lifting shaft to move up and down, thus improving the stability of the guide wheel's lifting.

[0028] The driving component can be a motor.

[0029] Preferably, the guide rail 1 has guide grooves 13 on both sides, the two sides of the guide grooves 13 have first arc surfaces 14, and the side of the guide wheel 5 has a second arc surface 15 that matches the first arc surface 14.

[0030] Specifically, the guide groove guides the movement of the guide wheel, thereby improving the guiding effect of the guide wheel on the main wheel. Due to the setting of the first arc surface and the second arc surface, when the guide wheel rises and falls in an alternating manner, the first arc surface and the second arc surface can fit together, thereby ensuring the fit between the guide wheel and the guide groove and improving the anti-tilting ability of the guide wheel.

[0031] Preferably, the guide rail 1 is provided with a guide bar 16 on the side facing the main wheel 2 along the moving direction of the main wheel 2, and the main wheel 2 is provided with a groove 17 that matches the guide bar 16 in the circumferential direction, so that when the main wheel 2 rolls along the guide rail 1, the guide bar 16 is engaged in the groove 17.

[0032] Specifically, by fastening the guide strip into the groove, the guide strip can guide the groove, thereby providing initial guidance to the main wheel. In conjunction with the guiding action of the guide wheel, the accuracy of the main wheel's transport direction can be further ensured.

[0033] Preferably, the lifting shaft 7 is provided with a first limiting ring 18 and a second limiting ring 19 at its end, and the guide wheel 5 is engaged between the first limiting ring 18 and the second limiting ring 19.

[0034] Specifically, the guide wheel is clamped and fixed by the first and second limiting rings. While ensuring smooth rotation of the guide wheel, the relative position stability between the guide wheel and the lifting shaft is improved, so as to ensure the cooperation effect between the lifting of the guide wheel and the guide groove.

[0035] Preferably, the mounting base 3 has a mounting plate 20 at one end, and the mounting plate 20 has a plurality of mounting holes 21 on its side.

[0036] Specifically, when installing the mounting base to the corresponding ship unloader, the mounting plate is aligned with the installation position of the ship unloader, and then bolts and other connecting parts are inserted through the mounting holes to connect to the mounting holes of the ship unloader, thereby improving the overall installation stability of the mounting base and rail clamp.

[0037] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
