Description

Technical Field

[0001] The utility model belongs to the technical field of automated movement, and in particular relates to a Mecanum wheel anti-deviation device. Background Art

[0002] Mecanum wheels, as omnidirectional wheels, have been widely used in automation fields such as logistics, warehousing, and robotics. However, since it is difficult to make the surface completely flat, the load distribution is uneven when transporting lighter loads, which causes the lighter loads to often deviate during operation on the Mecanum wheel platform, which seriously affects the positioning accuracy and operation stability of the equipment. Therefore, the development of an effective and reliable anti-deviation device is of great practical significance for improving the working performance of the Mecanum wheel platform. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the utility model aims to provide a Mecanum wheel anti-deviation device.

[0004] The utility model solves the technical problem by adopting the following technical scheme: a Mecanum wheel anti-deviation device is arranged at the edge of a Mecanum wheel platform, comprising: a plurality of blocking mechanisms, and at least one blocking mechanism is arranged on each side of the Mecanum wheel platform; the blocking mechanism comprises a blocking member, a base and a lifting assembly; the base is fixedly connected to one side of the Mecanum wheel platform, the lifting assembly is connected to the base, and the driving end of the lifting assembly is connected to the blocking member; the lifting path of the lifting assembly is kept vertical to the Mecanum wheel platform, and when the lifting assembly is in a lowered state, the upper surface of the blocking member is not higher than the upper surface of the Mecanum wheel platform; when the lifting assembly is in an ascending state, the upper surface of the blocking member is higher than the upper surface of the Mecanum wheel platform.

[0005] Its main working principle is to control the lifting and lowering of the blocking mechanism around the Mecanum wheel platform to constrain the edge of the Mecanum wheel platform and prevent the load from deviating during movement. Specifically, when the load passes normally on the surface of the Mecanum wheel platform, the lifting component is in a lowered state, and the upper surface of the blocking member is not higher than the upper surface of the Mecanum wheel platform. The movement of the load will not be hindered when entering or leaving the Mecanum wheel platform. However, when the load deviates on the surface of the Mecanum wheel platform, the lifting component will start and be in an ascending state, so that the upper surface of the blocking member is higher than the upper surface of the Mecanum wheel platform. At this time, the blocking member will play a blocking role, limiting the load from moving outside the edge of the Mecanum wheel platform and preventing it from exceeding the predetermined range, thereby achieving the effect of anti-deviation. The design of this anti-deviation device cleverly utilizes the lifting function of the lifting component, and realizes flexible constraint on the edge of the Mecanum wheel platform by changing the height of the blocking member.

[0006] Preferably, the baffle is a long strip of plate, and the length of the plate is opposite to the side length of the Mecanum wheel platform.

[0007] Preferably, the middle section of the plate protrudes toward the Mecanum wheel platform, and both sides of the plate gradually narrow outward toward the Mecanum wheel platform.

[0008] Preferably, the protrusion is made of elastic buffer material.

[0009] Preferably, the protrusion is detachably connected to the plate.

[0010] Preferably, a bottom plate is provided on the side of the stopper close to the base, the bottom plate is parallel to the plane of the Mecanum wheel platform, a guide column is provided on one end of the bottom plate facing the base, the guide column is parallel to the lifting path of the lifting assembly, and a guide hole that cooperates with the guide column is provided on the side of the base facing the bottom plate.

[0011] Preferably, a guide sleeve cooperating with the guide post is provided on the side of the guide hole facing away from the guide post.

[0012] Preferably, the guide posts, the guide holes and the guide sleeves are provided in two groups, respectively, and the two groups of the guide posts, the guide holes and the guide sleeves are respectively provided on both sides of the lifting assembly.

[0013] Preferably, the lifting assembly comprises a driving member;

[0014] The driving member is fixedly connected to the base, and the driving end of the driving member is connected to the blocking member.

[0015] Preferably, the upper surface of the Mecanum wheel platform is square or rectangular.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By setting a blocking mechanism around the Mecanum wheel platform, the blocking mechanism includes a blocking member, and the upper surface of the blocking member is higher than the upper surface of the Mecanum wheel platform, the load running on the surface of the Mecanum wheel platform is blocked, thereby avoiding the possible deviation of the load during the operation. This is of great significance for ensuring the stable operation of the Mecanum wheel platform and preventing equipment damage or operating errors caused by deviation.

[0018] At the same time, a lifting component is set in the blocking mechanism. The design of the lifting component allows the blocking mechanism to flexibly adjust its height as needed. When blocking is not needed, the lifting component is in a lowered state, and the upper surface of the blocking component is not higher than the upper surface of the Mecanum wheel platform, which will not affect the load entering or leaving the Mecanum wheel platform, ensuring the normal flow of the load. When it is necessary to prevent deviation, the lifting component can be raised to an ascending state to play a blocking role, greatly improving the overall practicality of the device.

[0025] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] The utility model discloses a Mecanum wheel anti-deviation device, such as Figure 1-Figure 3 As shown, the device is installed at the edge of the Mecanum wheel platform 1, and the edge of the Mecanum wheel platform 1 is blocked by the blocking mechanism 2, which effectively limits the load from moving toward the periphery of the Mecanum wheel platform 1, avoids the load from running off, and improves the stability of the load moving on the Mecanum wheel platform 1.

[0028] The overall structure of the device includes a plurality of blocking mechanisms 2, which are evenly distributed on each side of the Mecanum wheel platform 1 to ensure that the load can be effectively blocked from all directions. Figure 1 As shown, the surface of the Mecanum wheel platform 1 in this embodiment is a rectangle, and a blocking mechanism 2 is installed on each side of the rectangle, with a total of 4 blocking mechanisms 2.

[0029] Each blocking mechanism 2 includes a blocking member 20, a base 21 and a lifting assembly 22. Figure 4 As shown, first, the base 21 is used as the base of the blocking mechanism 2, and is firmly mounted on the edge of the Mecanum wheel platform 1 by bolts or other fixing methods. Secondly, the lifting component 22 is installed on the base 21, and its driving end is connected to the blocking member 20. The lifting path of the lifting component 22 is kept vertical to the upper surface of the Mecanum wheel platform 1. When the lifting component 22 is raised or lowered, it can drive its blocking member 20 to rise or fall, so as to adjust the height of the blocking member 20. The blocking member 20 adopts a long strip plate design, and its length is adjusted according to actual needs, specifically corresponding to the edge of the Mecanum wheel platform 1, so as to adapt to platforms of different sizes, and ensure that when the load is blocked, the load will not fall from the Mecanum wheel platform 1 through the two ends of the baffle. The lower end of the blocking member 20 is connected to the driving end of the lifting component 22, and the lifting and lowering of the blocking member 20 is realized by the driving of the lifting component 22. When the lifting assembly 22 is in the lowered state, the upper surface of the stopper 20 is not higher than the upper surface of the Mecanum wheel platform 1, so as to ensure that the load is not hindered from entering or leaving the Mecanum wheel platform 1. When the lifting assembly 22 is in the raised state, the upper surface of the stopper 20 is higher than the upper surface of the Mecanum wheel platform 1, forming a barrier to block the load moving to the edge of the Mecanum wheel platform 1 and prevent the load from deviating on the platform.

[0030] In some optional embodiments, the middle section of the plate protrudes toward the Mecanum wheel platform 1, and the two sides of the plate gradually narrow outward toward the Mecanum wheel platform 1. The protrusion in the middle can better gather the load at the edge of the Mecanum wheel platform 1 inward, while the two sides gradually narrow outward, resulting in the gradual expansion of the inlet and outlet ends of the Mecanum wheel platform 1, so that the load can enter or leave the Mecanum wheel platform 1 more smoothly.

[0031] In some optional embodiments, the protrusion is detachably connected to the plate to facilitate replacement of the protrusion.

[0032] In some optional embodiments, the lifting assembly 22 includes a driving member; the driving member is fixedly connected to the base 21, and a driving end of the driving member is connected to the stopper.

[0033] Specifically, when the driving member is a cylinder, the cylinder body of the cylinder is fixed on the base 21, and the telescopic rod of the cylinder is connected to the blocking member 20, and the lifting and lowering of the blocking member 20 is achieved by controlling the extension and retraction of the cylinder.

[0034] When the driving component is a motor, the lifting assembly 22 includes a motor, a screw and a ball bearing. The motor is fixedly connected to the base 21. The rotation of the motor drives the screw connected to the motor driving end to rotate. The ball bearing is installed on the stopper 20. When the screw rotates, the ball bearing mounted on the outer periphery of the screw moves up and down along the thread of the screw.

[0035] In some optional embodiments, a bottom plate 23 is provided on the side of the block 20 close to the base 21, and a guide column 24 is provided on one side of the bottom plate 23. The guide column 24 remains parallel to the lifting path of the lifting assembly 22. A guide hole 25 (not marked in the figure) that cooperates with the guide column 24 is provided on the side of the base 21 facing the bottom plate 23 and is used to cooperate with the guide hole 25 on the base 21. When the guide column 24 cooperates with the guide hole 25, the guide column 24 can only move vertically along the direction of the guide hole 25, so as to guide the block 20 in the vertical direction and realize the stable lifting and lowering of the block 20.

[0036] In some optional embodiments, in order to improve the matching accuracy and stability between the guide post 24 and the guide hole 25, a guide sleeve 26 may be provided on the side of the guide hole 25 facing away from the guide post 24. The guide sleeve 26 is a tubular component sleeved on the guide post 24, and its inner diameter matches the outer diameter of the guide post 24. The guide sleeve 26 can extend the guiding distance of the guide hole 25, further improving the stability and smoothness of the lifting movement. At the same time, the guide sleeve 26 can also play a certain buffering role, reducing the impact and vibration during the lifting process.

[0037] In some optional embodiments, the protrusions are made of elastic buffer material.

[0038] In some optional embodiments, the upper surface of the Mecanum wheel platform 1 is square or rectangular.

[0039] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
