Abstract
Description
Technical Field
[0001] This invention relates to the field of bulk material handling equipment technology, and more particularly to a cantilever belt conveyor drive support for a stacker-reclaimer. Background Technology
[0002] In the field of bulk material handling equipment technology, the cantilever belt conveyor drive with pitching motion in stacker and reclaimer is usually limited by structural space and maintenance requirements, and typically requires a rotating steel structure for support. To accommodate the changes in drive seat angle caused by the cantilever pitching motion, the drive seat is usually designed as a floating type.
[0003] Existing cantilever belt conveyor drive supports typically employ a rocker arm type support structure. This structure demands high installation precision, making installation and commissioning difficult. To accommodate the angular changes in the drive seat during pitching, the support rod needs sufficient length; however, this significantly amplifies drive seat sway caused by deviations in tolerances, a problem that is difficult to manage during equipment operation.
[0004] Furthermore, when users perform subsequent maintenance work on the conveyor belt, such as replacing the belt or replacing drive unit components, the drive seat of the swing arm type support structure often requires complex secondary adjustments, increasing the workload and difficulty of on-site maintenance. Therefore, how to provide a support seat that can adapt to changes in the cantilever pitch angle, reduce installation accuracy requirements, and effectively reduce drive seat sway is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0005] To address the aforementioned technical problems, a drive support base for a stacker-reclaimer cantilever belt conveyor is provided. In this invention, the drive support base provides support force to the drive base via a support wheel that can roll on a rotating steel structure, while simultaneously converting the swinging motion of the drive base into linear rolling of the support wheel on the rotating structure.
[0006] To achieve the above objectives, the present invention provides a drive support for a stacker-reclaimer cantilever belt conveyor, comprising: a drive support structure, a wheel set support, and a wheel set;
[0007] The wheelset is fixedly connected to the wheelset support base; The wheel set support is fixed to the drive seat structure; The drive mount structure is used to mount the drive device to form a drive unit; One end of the drive unit is supported on the rotating steel structure by the wheel set, and the other end is connected to the drive roller fixed on the tower or cantilever structure to form a hinge point.
[0008] Furthermore, the wheel assembly includes a spherical bearing, an axle, and a support wheel; The support wheel is sleeved on the shaft, and the spherical bearing is disposed between the support wheel and the shaft.
[0009] Furthermore, the spherical bearing is built into the wheel assembly to compensate for the angular deviation between the drive unit and the drive roller axis, so that the support wheel remains vertical in the working state.
[0010] Furthermore, a bushing for axial positioning of the spherical bearing is also fitted onto the shaft.
[0011] Furthermore, a shaft end baffle is installed at the end of the shaft, which is used to axially limit the bushing, the spherical bearing and the support wheel.
[0012] Furthermore, a rubber sealing ring is provided at the mating point between the support wheel and the shaft or the bushing.
[0013] Furthermore, the wheel assembly and the slewing steel structure have an open contact, so that the oscillation of the drive unit as the tower or cantilever structure pitches is converted into the linear rolling of the support wheel on the slewing steel structure.
[0014] Furthermore, the wheel support is fixed to the rear of the drive seat structure by bolting or welding.
[0015] Furthermore, the drive seat structure can be equipped with one or more corresponding wheel sets on the wheel set support seat according to the required support force of the drive unit.
[0016] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. The stacker-reclaimer cantilever belt conveyor drive support provided by the present invention improves the traditional closed swing arm support into a support wheel set with joint bearings, and successfully constructs a crank roller mechanism, which can effectively convert the circumferential oscillation of the drive seat caused by the pitch of the cantilever into the linear rolling of the support wheel on the rotating steel structure, thereby smoothly adapting to the angle change of the drive unit caused by the pitch of the cantilever.
[0017] 2. The stacker-reclaimer cantilever belt conveyor drive support seat provided by the present invention adopts a support wheel set to replace the previous long swing support rod, which significantly reduces the physical distance and relative movement amplitude between the drive seat and the slewing support structure. This compact design eliminates the amplification effect of long rods on small installation deviations, and fundamentally solves the problem of large swaying of the drive seat caused by manufacturing or installation deviations.
[0018] 3. The stacker-reclaimer cantilever belt conveyor drive support provided by the present invention has an open contact design between the support wheel and the rotating structure, which effectively releases the excessive constraints caused by installation deviations, and greatly reduces the stringent requirements of the belt drive system on the initial installation accuracy and the debugging difficulty.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0025] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples listed and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0026] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0027] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0028] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
[0029] like Figures 1 to 8 As shown, the present invention provides a drive support for a stacker-reclaimer cantilever belt conveyor, comprising: a drive support structure 1, a wheel set support 2, and a wheel set 3; Specifically, the wheel set 3 is fixedly connected to the wheel set support 2, and the wheel set support 2 is fixed to the tail of the drive seat structure 1 by bolt connection or welding.
[0030] In application, the drive base structure 1 is used to mount a drive device to form a drive unit 10. The drive device includes, but is not limited to, a motor and a reducer. The motor is only one preferred embodiment of the power source; those skilled in the art will understand that other power mechanisms, such as a hydraulic motor, can also be used instead. Figure 1 As shown, one end of the drive unit 10 is supported on the rotating steel structure 11 via the wheel set 3, and the other end is connected to the drive roller 13 fixed on the tower or cantilever structure 12, forming a hinge point. This connection method allows the tower structure 12, drive unit 10, wheel set 3, and rotating steel structure 11 to form a crank-roller mechanism. By eliminating the support swing rod previously connected to the rotating steel structure and instead using support wheels to provide support force to the drive base, the distance between the drive base and the support structure and the relative movement amplitude are significantly reduced, thereby fundamentally solving the problem of large swaying of the drive base during the operation of the belt conveyor.
[0031] Furthermore, such as Figure 5As shown, the internal structure of the wheel assembly 3 includes a spherical bearing 4, a shaft end baffle 5, a shaft 6, a bushing 7, a rubber seal ring 8, and a support wheel 9. The specific assembly relationship is as follows: the support wheel 9 is sleeved on the shaft 6, and the spherical bearing 4 is positioned between the support wheel 9 and the shaft 6. To achieve precise axial positioning and limiting, a bushing 7 is also sleeved on the shaft 6 for axial positioning of the spherical bearing 4; simultaneously, a shaft end baffle 5 is installed at the end of the shaft 6 for overall axial limiting of the bushing 7, the spherical bearing 4, and the support wheel 9. Furthermore, a rubber seal ring 8 is provided at the mating point between the support wheel 9 and the shaft 6 or bushing 7. The rubber seal ring 8 provides good sealing protection, effectively improving the reliability of the equipment in harsh loading and unloading environments, and also facilitating subsequent maintenance by the user.
[0032] In this embodiment, the spherical bearing 4 is built into the wheel assembly 3, and its core function is to compensate for the angular deviation between the axis of the drive unit 10 and the axis of the drive roller 13. The spherical bearing 4 ensures that the support wheel 9 remains vertical during operation. This design, combined with the open contact between the support wheel 9 and the rotating steel structure 11, effectively releases the excessive constraints caused by installation deviations, greatly reducing the precision requirements and debugging difficulty of the belt conveyor drive installation.
[0033] like Figures 6 to 8 As shown, regarding the motion conversion mechanism, the wheel assembly 3 and the slewing steel structure 11 employ an open contact. As the tower or cantilever 12 performs a pitching motion (lower or higher position), the drive unit 10 oscillates. This structure converts the angular change / oscillation of the drive seat caused by pitch into linear rolling of the support wheel 9 on the slewing steel structure 11. This open contact avoids the displacement constraints imposed by a closed swing arm structure, further enhancing the smoothness of the mechanism's operation.
[0034] Furthermore, depending on the required support force of the drive unit, one or more sets of corresponding wheels can be provided on the wheel support base.
[0035] Workflow: In actual operation, this technical solution connects one end of the drive unit 10 (carried by the drive base structure 1), which is equipped with a motor and a reducer, to the drive roller 13 fixed on the tower or cantilever structure 12 to form a hinge point. The other end is supported on the slewing steel structure 11 by the wheel set 3 fixed on the wheel set support seat 2 at the rear of the drive base structure 1. Thus, the tower or cantilever structure 12, the drive unit 10, the wheel set 3, and the slewing steel structure 11 together form a stable crank-roller mechanism. When the tower or cantilever structure 12 performs a pitching motion, the resulting angular displacement causes the drive unit 10 to swing synchronously around the hinge point at the drive roller 13. This swinging displacement is precisely controlled through the open contact between the wheel set 3 and the slewing steel structure 11. The displacement of the support wheel 9 is converted into linear rolling displacement on the surface of the rotating steel structure, thereby dynamically adapting to and releasing the positional changes caused by the cantilever pitch. During this dynamic conversion process, the spherical bearing 4, which is built into the wheel set 3 and axially positioned by the bushing 7 and limited by the shaft end baffle 5, plays a core compensating role. It can automatically absorb and correct the angular deviation between the axis of the drive unit 10 and the drive drum 13, ensuring that the support wheel 9, which is sleeved on the shaft 6 and protected by the rubber seal ring 8, always maintains a vertical force state. This floating support mechanism effectively releases the excessive constraints caused by installation deviations and fundamentally solves the problem of large swaying that is easy to be generated by traditional fixed support structures, providing technical guarantee for the smooth operation and convenient maintenance of the belt conveyor.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
