Description

Technical Field

[0001] The present application relates to the field of steel structure processing, and in particular, to a grinding device for steel structures. Background Art

[0002] Steel structures are widely used in the construction industry. In the processing of steel structures, grinding devices are usually required for grinding.

[0003] The grinding device generally includes a grinding wheel, a drive motor, and a transmission mechanism. The grinding wheel can grind the surface of the steel structure after rotating. The drive motor is used as a power source. The drive motor transmits power to the grinding wheel through the transmission mechanism, thereby driving the grinding wheel to rotate. The existing transmission mechanism generally includes a driving wheel, a driven wheel, and a transmission belt. The driving wheel is arranged on the power output shaft of the drive motor, and the driven wheel is connected to the grinding wheel to drive the grinding wheel to rotate. Then the grinding work of the steel structure is completed. In the actual assembly process, because the transmission belt needs to be put on the driven wheel and the driving wheel, it will inevitably lead to a certain assembly gap between the transmission belt and the driving wheel and the driven wheel. Therefore, when the power is transmitted, the power is not stable, which leads to unstable rotation of the grinding wheel. Therefore, when grinding, it is easy to be unable to perform accurate grinding due to the unstable rotation speed of the grinding wheel, which affects the grinding efficiency. Summary of the invention

[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a grinding device for a steel structure, including:

[0006] Bracket;

[0007] A driving member, arranged on the bracket;

[0008] A driving wheel, rotatably disposed on a power output shaft of the driving member;

[0009] A driven wheel is rotatably arranged on a bracket;

[0010] The belt body is sleeved on the driving wheel and the driven wheel to drive the driven wheel to rotate;

[0011] A grinding wheel connected to the driven wheel;

[0012] Wherein, the grinding device for the steel structure further comprises a tensioning mechanism, and the tensioning mechanism is used for tensioning the belt body.

[0013] In the technical solution provided by the present application, by setting a tensioning mechanism, the tension of the belt body can be adjusted according to the actual situation. In the working process, the power of the driving member can be evenly and stably transmitted to the grinding wheel, thereby ensuring the uniform rotation speed of the grinding wheel to increase the grinding accuracy.

[0014] Furthermore, the tensioning mechanism comprises at least a tensioning member and a positioning assembly, wherein the tensioning member is provided with at least a first position and a second position which are different relative to the belt body, and the positioning assembly is used to position the tensioning member at the first position or the second position.

[0015] In the technical solution provided by the present application, the tensioning piece has two different positions relative to the belt body, and the belt body can be loosened or tightened by adjusting the tensioning piece at two different positions, so that when the belt body is loosened, the installation and replacement of the belt body are facilitated, and when the belt body is tightened, the rotation conditions of the driving wheel and the driven wheel can be kept consistent, thereby ensuring that the grinding wheel can rotate stably and increasing the grinding accuracy.

[0016] When the belt body is tensioned, tensioning only from the inside or the outside will result in poor tensioning effect. To address this problem, the present application provides the following technical solutions:

[0017] Furthermore, at least two tensioning members are provided, and the two tensioning members are respectively located on the inner side and the outer side of the belt body.

[0018] In this solution, by arranging the belt body at the inner side and the outer side of the belt body respectively, the belt body can be tensioned from two aspects, thereby increasing the tensioning effect.

[0019] During use, the belt will gradually wear out, and due to thermal expansion and contraction, the tensioning process needs to be adjusted according to demand. To this end, this application provides the following solutions:

[0020] Furthermore, the tensioning member is slidably arranged on the bracket.

[0021] In the technical solution provided in the present application, the tensioning member is slidably arranged on the bracket, so that the tensioning member can move back and forth to adjust the tensioning degree.

[0022] Furthermore, the tensioning member includes a fixed shaft and a rotating wheel rotatably arranged on the fixed shaft.

[0023] Furthermore, the rotating wheel is provided with an annular groove which cooperates with the belt body.

[0024] Furthermore, a guide groove is provided on the bracket, and the fixed shaft is inserted into the guide groove to form a guiding fit with the guide groove.

[0025] When moving the two tensioning members, it is difficult to balance the tensioning effect of the two tensioning members on the belt body by moving the two tensioning members twice. To this end, the present application provides the following technical solutions:

[0026] Furthermore, the positioning assembly includes a positioning rod, a rotating gear, and a rotating rack; wherein the rotating rack is fixedly connected to the tensioning member, the rotating gear and the rotating rack are meshed with each other, the rotating gear is rotatably set on the positioning rod, and the positioning rod is set on the bracket.

[0027] In the technical solution provided in the present application, a rotating gear and a rotating rack are provided so that when the rotating gear rotates, the rotating rack is driven to move, and then the two tensioning members can be driven to move in opposite directions or in the opposite directions at the same time, thereby synchronously adjusting the tensioning effect of the two tensioning members.

[0028] Furthermore, the axial direction of the positioning rod is parallel to the rotation axis of the grinding wheel.

[0029] In the present solution, through this arrangement, the operator can be located in front of the grinding wheel when the rotating wheel is rotated, thereby avoiding safety accidents caused by touching the grinding wheel during operation.

[0030] The beneficial effects of this application are:

[0031] In the technical solution provided by the present application, by setting a tensioning mechanism, the tension of the belt body can be adjusted according to the actual situation. In the working process, the power of the driving member can be evenly and stably transmitted to the grinding wheel, thereby ensuring the uniform rotation speed of the grinding wheel to increase the grinding accuracy.

[0047] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein.

[0048] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0049] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0050] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0051] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0052] Reference Figures 1 to 3, a grinding device for a steel structure, comprising: a bracket, a driving member, a driving wheel, a driven wheel, a belt body, and a grinding wheel; wherein the driving member is fixedly connected to the bracket, and the driving member is a motor. The driving member transmits power to the driving wheel to drive the driving wheel to rotate. The driving wheel and the driven wheel are both rotatably arranged on the bracket, and the belt body is sleeved on the driving wheel and the driven wheel, and then after the driving wheel rotates, it can drive the driven wheel to rotate. The grinding wheel is connected to the driven wheel by transmission. In this way, the aforementioned device roughly constitutes an existing vertical grinder, and the user can drive the grinding wheel to rotate through the driving member to grind the parts that need to be polished.

[0053] The grinding device for steel structure also includes a tensioning mechanism for tensioning the belt body. The tensioning mechanism includes a tensioning member and a positioning assembly. The tensioning member is provided with at least a first position and a second position different from the belt body. The positioning assembly is used to position the tensioning member at the first position or the second position.

[0054] That is, the tensioning member can be plugged into any two positions on the bracket by plugging, so as to complete the loosening and tensioning of the belt body.

[0055] Of course, in order to facilitate the use of the present application, the following specific solution is also provided: the tensioning member is slidably arranged on the bracket. Specifically, the tensioning member includes a fixed shaft and a rotating wheel rotatably arranged on the fixed shaft. The rotating wheel is provided with an annular groove that cooperates with the belt body. The belt body and the annular groove correspond to each other, and when the belt body and the rotating wheel contact each other, because the rotating wheel can rotate, there will not be a large friction force.

[0056] In this solution, the tensioning member is slidably arranged on the bracket. Specifically, a guide groove is arranged on the bracket, and the fixed shaft is inserted into the guide groove to form a guide match with the guide groove. The arrangement direction of the guide groove is perpendicular to the arrangement direction of the belt body. In this way, when the fixed shaft moves in the guide groove, the belt body can be relaxed or tensioned.

[0057] Furthermore, at least two tensioning members are provided, and the two tensioning members are respectively located on the inner side and the outer side of the belt body. Correspondingly, two parallel guide grooves are also required to be provided on the bracket, so that when the two tensioning members are moved in opposite directions, the belt body can be tensioned. When they are moved in the opposite direction, the belt body can be loosened.

[0058] To this end, the present application provides the following positioning assembly to synchronously move the tensioning member. Specifically, the positioning assembly includes a positioning rod, a rotating gear, and a rotating rack; the rotating rack is fixedly connected to the tensioning member. Among them, there are two rotating racks, and the two rotating racks are arranged opposite to each other. The two tensioning members are respectively fixedly connected to the rotating racks.

[0059] The rotating gear is rotatably arranged on the bracket, and the rotating gear is respectively meshed with the two rotating racks. In this way, after the rotating gear rotates, it can drive the two rotating racks to move in the opposite direction. The rotating gear sleeve is arranged on the positioning rod, and the positioning rod is fixedly arranged on the bracket. The axial direction of the positioning rod is parallel to the rotation axis of the grinding wheel. Furthermore, the rotating gear can be directly in front of the grinding wheel.

[0060] When adjusting the tightness, the rotating gear needs to be rotated, and when in normal use, the rotating gear needs to be fixed. For this reason, in the solution provided by the present application, the rotating gear is threadedly connected to the positioning rod. Therefore, when driving the rotation, sufficient torque needs to be provided. In this way, when adjusting the tightness, a tool such as a wrench is used to drive the rotating gear to rotate, and after the adjustment is completed, it is difficult for the rotating rack to drive the rotating gear to rotate, thereby achieving the purpose of positioning.

[0061] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
