Description

Technical Field

[0001] This utility model relates to the field of heavy metallurgical equipment technology, and in particular to an adjustable walking device for heavy grinding machines. Background Technology

[0002] Heavy-duty grinding machines are mainly used for removing defects such as oxide scale and cracks from the surface of large blanks. They typically use a high-power motor to drive a heavy-duty grinding wheel at high speed to provide tangential grinding force, while a hydraulic cylinder provides positive pressure. The traveling device is driven by a hydraulic cylinder to move at high speed to achieve grinding coverage across the width of the blank. However, due to the unevenness of the blank and the inconsistency of the abrasive grains during actual grinding, in addition to the normal grinding force, a large eccentric load is usually generated on the traveling device. This leads to a series of problems such as large vibrations during operation, easy deviation from the traveling direction, and easy damage to the wheel assembly, seriously affecting the grinding quality and efficiency, and posing significant safety hazards. Utility Model Content

[0003] This utility model discloses an adjustable walking device for a heavy-duty grinding machine, which aims to solve the technical problems that occur during the grinding process. The unevenness of the blank and the inconsistency of the abrasive grains usually generate a large off-center load on the walking device in addition to the normal grinding force, resulting in a series of problems such as large vibration during operation, easy deviation of the walking direction, and easy damage to the wheel set. These problems seriously affect the grinding quality and efficiency and pose significant safety hazards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable traveling device for a heavy-duty grinding machine includes a box-type frame and a track. Vertical traveling wheels are rotatably connected to both ends of the box-type frame via vertical traveling wheel axles. The vertical traveling wheels are in contact with the upper end of the track and are used for traveling and bearing vertical forces.

[0006] The box frame is equipped with guide supports on both sides in pairs. A horizontal travel wheel axle is installed in the mounting groove of the guide support. A horizontal travel wheel is rotatably mounted at the lower end of the horizontal travel wheel axle. A compression spring assembly is provided at the connection between the horizontal travel wheel axle and the guide support. The compression spring assembly is connected to the guide support through a fixing bolt, a compression spring support, a transition washer, and a lock nut.

[0007] The front and rear ends of the box-type vehicle frame are equipped with air-blowing cleaning mechanisms for cleaning impurities from the track surface.

[0008] The upper surfaces at both ends of the track are provided with upper arc plates for braking the vertical traveling wheels, and the outer sides of both ends of the track are provided with side arc plates for braking the horizontal traveling wheels. The braking effect is stronger the closer to the end of the track.

[0009] In a preferred embodiment, anti-rotation pressure plates are installed at the groove positions at the ends of the vertical travel wheel axles and on the outer side of the box frame, and bearings are installed inside both the vertical travel wheel and the horizontal travel wheel.

[0010] In a preferred embodiment, the horizontal traveling wheels are used in pairs with adjacent vertical traveling wheels, and the three are arranged in a triangular configuration.

[0011] In a preferred embodiment, the air-blowing cleaning mechanism includes a housing fixed to the front and rear ends of the box frame, the housing having a built-in micro air pump, an air inlet on the upper outer side of the housing, and an air outlet on the lower end of the housing.

[0012] In a preferred embodiment, the curvature of the upper and side arc plates increases as they approach the end of the track.

[0013] In a preferred embodiment, the outer surfaces of the upper arc plate and the side arc plate are provided with a plurality of resistance grooves.

[0014] In a preferred embodiment, the resistance grooves are more densely distributed closer to the end of the track.

[0015] The adjustable walking device for heavy-duty grinding machines provided by this utility model has the following technical effects.

[0016] Firstly, it adopts a track-type bidirectional flat wheel concept. Compared with the traditional flange wheel set design, the combination of horizontal and vertical walking flat wheels significantly reduces walking friction while further improving the stability and reliability of the operation. The compression spring set used for the horizontal walking wheel set can automatically adjust the thickness of the compression spring according to the magnitude of the off-center load, and the adjustment direction is along the direction of the guide support to ensure controllability. This can effectively improve the durability of the walking device, as well as the smoothness and safety of the walking process, and ensure the quality of grinding.

[0017] Secondly, the upper arc plate on the end surface of the track can provide resistance to the vertical traveling wheels and brake them. Similarly, the side arc plate can also brake the horizontal traveling wheels, thereby avoiding derailment or collision.

[0018] Thirdly, the air-blowing cleaning mechanism can blow air downwards through a miniature air pump inside the casing and blow it onto the track surface from the air outlet, thereby cleaning impurities on the track surface, reducing wear on the wheels, and improving stability and service life.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "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, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-7 An adjustable walking device for a heavy-duty grinding machine includes a box frame 1 and a track 14. Vertical walking wheels 2 are rotatably connected to both ends of the box frame 1 via vertical walking wheel axles 3. The vertical walking wheels 2 are in contact with the upper end of the track 14. The vertical walking wheels 2 are used for walking and bear vertical force.

[0030] The box frame 1 has guide supports 7 installed in pairs on both sides. A horizontal travel wheel axle 6 is installed in the mounting groove of the guide support 7. A horizontal travel wheel 5 is rotatably installed at the lower end of the horizontal travel wheel axle 6. A compression spring assembly 8 is provided at the connection between the horizontal travel wheel axle 6 and the guide support 7. The compression spring assembly 8 is connected to the guide support 7 through a fixing bolt 9, a compression spring support 10, a transition pad 11 and a locking nut 12.

[0031] In this embodiment, the box frame 1 of this application is used to carry a heavy-duty grinding machine and move along the track 14. During the movement, the vertical travel wheel 2 contacts the upper end of the track 14, thereby supporting the vertical gravity of the equipment and providing travel power. The horizontal travel wheel 5 is used to limit the horizontal position of the box frame 1. The horizontal travel wheel axle 6 is connected to the guide support 7 through the compression spring assembly 8. The horizontal amplitude generated during the operation can be transmitted to the compression spring assembly 8, and the compression amount of the compression spring assembly 8 changes according to the actual off-center load, thereby adaptively adjusting the position of the horizontal travel wheel axle 6 and the horizontal travel wheel 5 to reduce the impact of the off-center load.

[0032] Furthermore, such as Figure 1 and Figure 7 The front and rear ends of the box frame 1 are provided with an air cleaning mechanism 13 for cleaning impurities on the surface of the track 14. The air cleaning mechanism 13 includes a housing 1301 fixed to the front and rear ends of the box frame 1. The housing 1301 has a built-in micro air pump, an air inlet 1302 is opened on the outer side of the upper end of the housing 1301, and an air outlet 1303 is opened at the lower end of the housing 1301.

[0033] In this embodiment, while the box frame 1 moves along the track 14, the air blowing cleaning mechanism 13 can blow air downwards through the miniature air pump inside the outer shell 1301 and blow it onto the surface of the track 14 from the air outlet 1303, thereby cleaning the impurities on the surface of the track 14, reducing the wear of impurities on the wheels, improving stability and service life. The miniature air pump model is "TAN21-4".

[0034] Reference Figure 1 and Figure 4 In a preferred embodiment, upper arc plates 15 are provided on the upper surfaces of both ends of the track 14 for braking the vertical traveling wheels 2, and side arc plates 16 are provided on the outer sides of both ends of the track 14 for braking the horizontal traveling wheels 5. The braking effect is stronger the closer to the end of the track 14.

[0035] In this embodiment, when the box frame 1 experiences a brake failure, the upper arc plate 15 on the end surface of the track 14 can provide resistance to the vertical traveling wheel 2 and brake it. Similarly, the side arc plate 16 can also brake the horizontal traveling wheel 5, thereby preventing derailment or collision.

[0036] Furthermore, the curvature of the upper arc plate 15 and the side arc plate 16 is greater as they approach the end of the track 14, resulting in a stronger braking effect as they approach the end of the track 14.

[0037] Furthermore, the outer surfaces of the upper arc plate 15 and the side arc plate 16 are provided with a number of resistance grooves 17. The resistance grooves 17 are more densely distributed closer to the end of the track 14. The resistance grooves 17 can effectively improve the friction and resistance of the traveling wheel, and the closer they are to the end of the track 14, the denser they are, and the stronger the resistance.

[0038] Specifically, anti-rotation pressure plates 4 are installed at the groove position at the end of the vertical travel wheel axle 3 and on the outer side of the box frame 1, and bearings are installed inside both the vertical travel wheel 2 and the horizontal travel wheel 5.

[0039] Specifically, the horizontal traveling wheels 5 and the adjacent vertical traveling wheels 2 are used in pairs, and the three are arranged in a triangle to improve the overall stability of the traveling wheels.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
