Description

Technical Field

[0001] The utility model relates to the technical field of storage vehicle parts, in particular to a storage vehicle slewing bearing protection device. Background Art

[0002] Electric storage trucks are a type of light and small storage industrial vehicle that is widely used at home and abroad and has huge market potential. It is powered by batteries, driven by motors, centrally controlled by joysticks, and driven in a standing position. Electric storage trucks are easy to operate, stable, fast, compact, flexible to operate, low noise, and low pollution. They can be operated in shopping malls, supermarkets, warehouses, freight yards, workshops and other places. They are especially suitable for use in light industries such as food, textiles, and printing. They are widely used in the warehousing industry because of their compact body, flexible mobility, light weight, and good environmental performance. With the development of the logistics industry, although storage trucks have received more and more attention due to their small size, flexible mobility, and simple operation, the demand for storage trucks is getting higher and higher due to the continuous increase in labor costs, and the market has more and more requirements for the working conditions of storage trucks.

[0003] In the prior art, CN210554228U discloses an electric storage vehicle hood that is easy to disassemble and assemble, which solves the problem that the existing electric storage vehicle hood is inconvenient to disassemble and cannot meet the needs of users. In addition, the mechanical steering device used in the existing storage vehicle basically adopts a structure that is connected up and down as one, directly connecting the steering bearing of the steering and drive unit, or connected through components such as gears, wherein the drive unit is fixed to the body, or connected to the body through springs, damping and other shock-absorbing flexible connections. The steering handle is rigidly connected to the drive unit, and the steering device in which the drive unit is directly riveted to the body, the pressure on the drive wheel of the drive unit will change greatly due to the rugged road surface, which is easy to cause adverse consequences such as steering failure or heavy steering, and the impact on the entire body is completely transmitted to the driver's hand, and the drive unit is prone to vertical movement, resulting in poor operating comfort; when the body is unloaded or fully loaded, the steering force changes greatly; in addition, most of the existing mechanical steering devices still have the defects of low mechanical efficiency, complex structure, high precision requirements and high cost. In view of the above problems, CN106379396A proposes a warehouse truck steering device and a warehouse truck having the same. By setting a torque transmission structure to cut off the rigid connection between the drive unit and the operating handle, the vertical movement of the drive unit can be completely isolated, thereby avoiding uncomfortable operating feeling and improving operating comfort.

[0004] At the same time, the existing technology also has the problem that the slewing bearing of the storage truck is exposed, which leads to the vehicle being used for a long time in relatively dirty and muddy working conditions, and debris accumulates in the inner and outer ring raceways of the slewing bearing, causing the slewing bearing to get stuck. In order to solve this problem, it is necessary to protect the slewing bearing, and thus the present utility model is proposed. Utility Model Content

[0005] The utility model aims to provide a slewing bearing protection device for a storage vehicle, so as to solve the problems that the slewing bearing of the existing storage vehicle is exposed, resulting in the vehicle being used for a long time in dirty and muddy working conditions, and that debris accumulates in the inner and outer ring raceways of the slewing bearing, causing the slewing bearing to get stuck.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A slewing bearing protection device for a storage vehicle comprises a drive assembly, a slewing bearing, a frame mounting plate, inner and outer ring raceways and a slewing bearing protection cover, and also comprises a plurality of screws M10 and screws M8; wherein:

[0008] The slewing bearing protective cover is fixed between the slewing bearing and the driving assembly, and the inner and outer ring raceways are located between the slewing bearing and the slewing bearing protective cover;

[0009] The slewing bearing includes a slewing bearing outer ring and a slewing bearing inner ring. The slewing bearing outer ring is fixed to the frame mounting plate by the screw M8; the slewing bearing inner ring is connected to the drive assembly by the screw M10 to realize the relative movement of the drive.

[0010] Preferably, the model of the screw M10 is screw M10×35, and the model of the screw M8 is screw M8×35.

[0011] Preferably, the slewing bearing protective cover is fixed between the slewing bearing and the drive assembly by means of the screw M10.

[0012] Preferably, the slewing bearing protective cover is a trapezoidal structure with its opening facing the slewing bearing.

[0013] The existing slewing bearing is fixed to the frame mounting plate by screws, and then directly connected to the drive assembly by screws. This connection method causes the inner and outer ring raceways of the slewing bearing to be exposed. If the working conditions are relatively dirty, dusty, and there is a lot of mud, the slewing bearing may be stuck due to the long-term accumulation of debris splashing onto the inner and outer ring raceways of the slewing bearing. Compared with the prior art, the utility model proposes a slewing bearing protection device for a storage vehicle, which adds a slewing bearing dust cover with a simple structure, low cost and easy installation between the slewing bearing and the drive assembly to avoid the slewing bearing being exposed, so as to block the drive assembly during operation, effectively avoiding the problem of debris splashing onto the inner and outer ring raceways of the slewing bearing and accumulating for a long time, causing the slewing bearing to be stuck, thereby meeting different working conditions requirements on the market.

[0017] like Figure 1 As shown, a slewing bearing protection device for a storage vehicle is exemplarily described, including a driving assembly 1, a slewing bearing 2, a frame mounting plate 4, inner and outer ring raceways 7 and a slewing bearing protection cover 3, and also including a plurality of screws M105 and screws M86; wherein the slewing bearing protection cover 3 is fixed between the slewing bearing 2 and the driving assembly 2, and the inner and outer ring raceways 7 are located between the slewing bearing 2 and the slewing bearing protection cover 3; the slewing bearing 2 includes a slewing bearing outer ring and a slewing bearing inner ring, and the slewing bearing outer ring is fixed to the frame mounting plate 4 by means of screws M86; and the slewing bearing inner ring is connected to the driving assembly 1 by means of screws M105 to realize the relative movement of the drive.

[0018] In some embodiments, the model of the screw M10 5 is screw M10×35, and the model of the screw M8 6 is screw M8×35.

[0019] In some embodiments, the slewing bearing protective cover 3 is fixed between the slewing bearing 2 and the driving assembly 1 by screws M105.

[0020] In some embodiments, the slewing bearing protection cover 3 is a trapezoidal structure with an opening facing the slewing bearing.

[0021] The utility model designs a slewing bearing protective cover that meets market working conditions, wherein the drive installation includes screws M8×35, screws M10×35, a slewing bearing, a drive assembly, and a slewing bearing protective cover; the slewing bearing outer ring is installed on a frame mounting plate by screws M8×35 to play a fixing role; the slewing bearing inner ring is connected to the drive assembly by screws M10×35 to achieve relative movement of the drive; the slewing bearing protective cover is installed between the slewing bearing and the drive assembly and is fixed by screws M10×35, and there is no need to add other fixing methods.

[0022] When the warehouse truck is running, if the working conditions are dirty, dusty and muddy, adding a slewing bearing protective cover between the slewing bearing and the drive assembly can prevent the drive assembly from splashing debris onto the inner and outer ring raceways of the slewing bearing during operation, thereby avoiding the phenomenon of slewing bearing getting stuck due to long-term accumulation, which is very practical.
