Description

Technical Field

[0001] The present invention relates to the technical field of roller mounting structures, and particularly relates to a traveling roller mounting structure and a movable device. Background Art

[0002] During the electrical installation and integration of movable devices (mainly instrument control devices), rollers need to be installed at the bottom of the devices. After the instrument control devices are integrated, the rollers need to be removed for transportation and packaging. The existing roller mounting method for movable devices is: directly fixed to the bottom of the device through a screw / bolt assembly. Only the screws / bolts on one side of the roller mounting base can be removed on one side of the device, resulting in the need to lift the device by a hoisting device such as a crane during the removal process, and then manually remove the screw / bolt assembly from the operating space at the bottom of the device. However, the instrument control devices are large in size and heavy in weight, and there are safety hazards such as device tipping after being lifted, which is likely to cause personal injuries and device damage. Summary of the Invention

[0003] Aiming at the technical problems of inconvenient disassembly of rollers of existing traveling devices and potential safety hazards, the present invention provides a traveling roller mounting structure and a movable device, which can complete the disassembly of the rollers without lifting the movable device by a hoisting device, solve the safety problems during the disassembly of the rollers, and the disassembly is simple and convenient, and the disassembly efficiency of the rollers is high.

[0004] The present invention is realized by the following technical solutions:

[0005] In a first aspect, the present invention provides a traveling roller mounting structure, including: a roller mechanism; a connecting seat, the connecting seat is mounted on the top of the roller mechanism, and a connecting protrusion is provided on the top of the connecting seat; a mounting seat, a mounting groove is provided at the bottom of the mounting seat, and a mounting through hole is provided on one side of the mounting groove; a limiting member, the limiting member is provided on the top of the connecting protrusion, the limiting member is a long strip extending along the width direction of the connecting seat, a limiting hole is provided on one side of the limiting member, and the limiting member can rotate along a preset axis in the mounting groove; a limiting connecting member, one end of the limiting connecting member can pass through the mounting through hole and be connected to the limiting hole; wherein, in the mounting state, the mounting seat is mounted on the bottom of the movable device, the bottom plate of the movable device is clamped between the limiting member and the connecting seat, and the limiting connecting member connects the limiting member and the mounting seat.

[0006] It should be noted that for existing movable devices, the rollers are directly fixed to the bottom of the device through screw / bolt assemblies. Only the screws / bolts on one side of the roller mounting base can be removed on one side of the device. As a result, during the removal process, a lifting device such as a crane is required to lift the device, and then workers need to remove the screw / bolt assembly from the operating space at the bottom of the device manually. However, the instrument control device is large in size and heavy in weight. After being lifted, there are safety hazards such as the device tipping over, which can easily cause personal injuries and equipment damage. Moreover, due to the limitations of the installation structure of the rollers themselves, multiple nuts need to be removed during disassembly, and the operation of screwing the nuts is restricted by the rollers, making it inconvenient to implement.

[0007] In view of this, the walking roller mounting structure provided by the present invention includes a roller mechanism, a connecting seat, a mounting seat, a limiting member, and a limiting connecting member; the connecting seat is installed on the top of the roller mechanism so as to install the roller mechanism on the movable device through the connecting seat. At the same time, a connecting protrusion is provided on the top of the connecting seat, and the limiting member is provided on the top of the connecting protrusion so that there is a corresponding gap between the limiting member and the top of the connecting seat, and the size of this gap is usually adapted to the thickness of the bottom plate of the movable device; an installation groove is provided at the bottom of the mounting seat, an installation through hole is provided on one side of the installation groove, the limiting member is a long strip extending along the width direction of the connecting seat, a limiting hole is provided on one side of the limiting member, and the limiting member can rotate along a preset axis in the installation groove, and one end of the limiting connecting member can pass through the installation through hole and be connected to the limiting hole.

[0008] During installation, the mounting seat is installed at the bottom of the movable device, and there is a passage for the limiting member to pass through in the part of the movable device facing the installation groove. Then, the limiting member is inserted into the installation groove through this passage, and the connecting seat is rotated so that the bottom plate of the movable device is clamped between the limiting member and the connecting seat, thereby vertically (axially) limiting the roller mechanism through the limiting member and the connecting seat to ensure that the entire installation mechanism can provide sufficient supporting force to support the movable device. Moreover, the limiting hole is aligned with the installation through hole, and then the limiting connecting member is passed through the installation through hole and connected to the limiting hole to limit the circumferential freedom degree of the connecting seat, so as to quickly install the roller mechanism on the movable device.

[0009] When the roller mechanism needs to be disassembled, only the limiting connecting member needs to be removed first, and then the movable device is slightly lifted upward so that there is a gap between the roller and the ground. Then, the connecting seat is rotated, and the connecting seat can be removed from the movable device. There is no need to lift the device by a crane or the like to lift the movable device to the height of the manually operable space at the bottom, avoiding the safety problems when personnel enter the bottom of the device during the roller disassembly process. Moreover, during the disassembly process, only the limiting connecting member needs to be removed, and the disassembly is simple and convenient, and the disassembly efficiency of the roller is high.

[0010] In summary, for the walking roller mounting structure provided by the present invention, the roller can be disassembled without lifting the movable device by a lifting device, which solves the safety problem during the roller disassembly process, and the disassembly is simple and convenient, and the disassembly efficiency of the roller is high.

[0014] In an alternative embodiment of the present application, the limiting holes are arranged on both sides in the length direction of the limiting member, and the mounting through holes are arranged on both opposite sides of the mounting groove, so that the mounting seat and the limiting member do not need to be aligned during installation, realizing a foolproof design and improving the installation efficiency of the roller mechanism.

[0016] In an alternative embodiment of the present application, the mounting groove is a circular groove, so as to minimize the volume of the mounting seat as much as possible, thereby reducing the size of the corresponding mounting chute opened on the movable device, and avoiding reducing the structural strength of the wall plate of the movable device due to the setting of the mounting channel of the mounting seat.

[0017] In an alternative embodiment of the present application, both opposite sides of the mounting groove are through groove structures, and the line connecting the two through groove structures of the mounting groove is perpendicular to the axis of the limiting hole, which can further reduce the size of the mounting seat in the length direction.

[0018] In an alternative embodiment of the present application, the mounting seat is a square structure to facilitate the installation of the mounting seat.

[0019] In an alternative embodiment of the present application, mounting screw holes are arranged at each corner of the mounting seat, so as to facilitate the fixed installation of the mounting seat on the movable device through a screw rod.

Then, the connecting seat is rotated, and the connecting seat can be removed from the mobile device. There is no need to lift the device by a crane or the like to lift the mobile device to the height of the operable space at the bottom of the manual. This avoids the safety problems that personnel may enter the bottom of the device during the roller disassembly process. Moreover, during the disassembly process, only the limit connecting piece needs to be disassembled, and the disassembly is simple and convenient, and the disassembly efficiency of the roller is high.

[0022] In an optional embodiment of the present application, an installation chute is opened on one side wall at the lower end of the device body, and the installation chute can allow the installation seat to slide into the device body, so as to facilitate fixing the installation seat in the device body by sliding the installation seat into the device body through the installation chute.

[0023] In an optional embodiment of the present application, a clamping hole is opened at the lower end of the device body, and the clamping hole is adapted to the limiting member, so that the limiting member can be inserted into the device body through the clamping hole, while ensuring that the limiting member can extend into the device body, the size of the clamping hole is reduced as much as possible to avoid affecting the structural strength of the bottom plate of the device body due to the opening of the clamping hole; wherein, when the limiting member is inserted into the device body, the limiting member is accommodated in the installation groove to ensure that the connecting seat can be connected to the installation seat and the device body.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0045] In the description of the embodiments of the present application, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is customarily placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0046] In the description of the present application, unless otherwise clearly defined and limited, the terms "set", "install", "connect", and "couple" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements.

[0047] It should be noted that existing movable devices directly fix the rollers at the bottom of the device through screw / bolt assemblies, and only the screws / bolts on one side of the roller mounting seat can be removed on one side of the device. As a result, during the removal process, a lifting device such as a crane is required to lift the device, and then the screw / bolt assembly is removed manually from the operating space at the bottom of the device. However, the instrument control device is large in size and heavy in weight, and there are safety hazards such as the device tipping over after being lifted, which is likely to cause personal injuries and equipment damage. Moreover, due to the installation structure limitation of the rollers themselves, multiple nuts need to be removed during disassembly, and the operation of screwing the nuts is restricted by the rollers, making it inconvenient to implement.

[0048] In response to this, the inventor has innovatively designed the following technical solutions, and the specific implementation solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0049] Embodiment 1

[0050] Combined with Figure 1 、 Figure 2 and Figure 3, this embodiment provides a walking roller mounting structure, including: a roller mechanism 10; a connecting seat 20, the connecting seat 20 is mounted on the top of the roller mechanism 10, and a connecting protrusion 21 is provided on the top of the connecting seat 20; a mounting seat 30, a mounting groove 31 is provided at the bottom of the mounting seat 30, and a mounting through hole 32 is provided on one side of the mounting groove 31; a limiting member 40, the limiting member 40 is provided on the top of the connecting protrusion 21, the limiting member 40 is a strip-shaped extending along the width direction of the connecting seat 20, a limiting hole 41 is provided on one side of the limiting member 40, and the limiting member 40 can rotate along a preset axis in the mounting groove 31; a limiting connecting member 50, one end of the limiting connecting member 50 can pass through the mounting through hole 32 and be connected to the limiting hole 41; wherein, in the mounted state, the mounting seat 30 is mounted at the bottom of the movable device, the bottom plate of the movable device is clamped between the limiting member 40 and the connecting seat 20, and the limiting connecting member 50 connects the limiting member 40 and the mounting seat 30.

[0051] Regarding the roller mechanism 10, it can be understood that it includes a roller body and a mounting frame. The roller body is rotatably mounted on the mounting frame, and the mounting frame can be a fixed frame (rollers in a fixed direction) or a gimbal frame (swivel wheels).

[0052] Specifically, the roller body includes:

[0053] Tread, the part in contact with the ground, and the material determines the performance (rubber / polyurethane: quiet, anti-slip; nylon / metal: wear-resistant, load-bearing); usually, the tread is designed with patterns to enhance the grip or reduce ground wear (for example, smooth wheels are suitable for wooden floors, and toothed wheels are suitable for rough ground);

[0054] Hub, the central structure of the wheel, connecting the bearing and the mounting frame, and the material is mostly metal or high-strength plastic;

[0055] Shock-absorbing structure, (such as springs or elastic bushings), used to absorb shocks;

[0056] Bearing, to reduce friction and ensure smooth rolling. Common bearings include ball bearings and needle bearings. Ball bearings have the characteristics of high rotational speed and low resistance, while needle bearings have high radial load capacity (industrial equipment).

[0057] For the mounting frame of the roller, it is usually made of metal (steel / aluminum) and is used to support the connection between the wheel and the device.

[0058] Combined with Figure 3, the installation groove 31 is a circular groove to minimize the volume of the mounting base 30 as much as possible, thereby reducing the size of the corresponding installation chute 61 opened on the movable device, and avoiding reducing the structural strength of the wall plate of the movable device due to the setting of the installation passage of the mounting base 30.

[0059] Generally, the mounting base 30 has a square structure to facilitate the installation of the mounting base 30.

[0060] In this embodiment, the installation groove 31 is a circular groove. Two opposite sides of the installation groove 31 are through groove structures, and the line connecting the two through groove structures of the installation groove 31 is perpendicular to the axis of the limiting hole 41. That is to say, installation through holes 32 communicating with the installation groove 31 are provided on two opposite sides of the mounting base 30, and through grooves communicating with the installation groove 31 are provided on the other two opposite sides of the mounting base 30. Thus, the dimensional requirements for the width direction of the mounting base 30 are low, and the dimensional requirements for the length direction of the mounting base 30 can be further reduced.

[0061] It can be understood that mounting screw holes 33 are provided at each corner of the mounting base 30 (mounting screw holes 33 are opened at all four corners) to facilitate the fixed installation of the mounting base 30 on the movable device through screws.

[0062] For the connection method between the connection seat 20 and the roller mechanism 10, it can be a fixed connection method such as screwing, pinning, riveting, etc. or a detachable connection method. In this embodiment, the connection seat 20 is fixedly connected to the roller mechanism 10 (fixedly connected to the mounting frame) through a plurality of bolts to facilitate the quick connection of the connection seat 20 and the roller mechanism 10. Generally, the connection seat 20 is provided with four countersunk bolt holes, and correspondingly, ten through holes are provided on the mounting frame of the roller mechanism 10 to fix the connection seat 20 on the roller mechanism 10 through the cooperation of countersunk bolts and corresponding nuts.

[0063] Combined with Figure 3 , the connection protrusion 21 has a cylindrical structure to ensure that the connection protrusion 21 can rotate smoothly on the bottom plate of the movable device. Of course, the connection protrusion 21 can also be a prismatic structure, such as a hexagonal prism, an octagonal prism, etc.

[0064] In this embodiment, the width of the limiting member 40 is the same as the diameter of the connection protrusion 21, and the limiting member 40 and the connection protrusion 21 are concentrically arranged to minimize the size of the passage for the limiting member 40 to pass through as much as possible, thereby avoiding affecting the structural strength of the device bottom plate due to the through hole for the limiting member 40 to pass through.

[0065] It can be understood that if the connecting protrusion 21 is circular, the centroid of the limiting member 40 is on the axis of the connecting protrusion 21. If the connecting protrusion 21 is a prismatic structure, the centroid of the limiting member 40 is on the center line of the connecting protrusion 21. At the same time, the length direction of the limiting member 40 is arranged parallel to the width direction / length direction of the connecting seat 20.

[0066] Combined with Figure 3 and Figure 4 again, the limiting holes 41 are arranged on both sides of the limiting member 40 in the length direction, and the mounting through holes 32 are arranged on both opposite sides of the mounting groove 31, so that when installing, it is not necessary to align the mounting seat 30 and the limiting member 40, realizing a foolproof design and improving the installation efficiency of the roller mechanism 10.

[0067] To further reduce the size of the mounting seat 30, in this embodiment, the connecting member is a rectangular block with rounded corners at all four corners.

[0068] Combined with Figure 10 again, in this embodiment, the limiting connecting member 50 is a screw rod, and the limiting hole 41 is a threaded hole, so as to axially limit the limiting connecting member 50 and prevent the limiting connecting member 50 from falling off during the working process, ensuring the installation stability of the roller mechanism 10.

[0069] In summary, the walking roller mounting structure provided in this embodiment includes a roller mechanism 10, a connecting seat 20, a mounting seat 30, a limiting member 40, and a limiting connecting member 50; the connecting seat 20 is mounted on the top of the roller mechanism 10, so that the roller mechanism 10 can be mounted on a movable device through the connecting seat 20. At the same time, a connecting protrusion 21 is provided on the top of the connecting seat 20, and the limiting member 40 is provided on the top of the connecting protrusion 21, so that there is a corresponding gap between the top of the limiting member 40 and the connecting seat 20, and the size of this gap is usually adapted to the thickness of the bottom plate of the movable device; a mounting groove 31 is provided at the bottom of the mounting seat 30, a mounting through hole 32 is provided on one side of the mounting groove 31, the limiting member 40 is a long strip extending along the width direction of the connecting seat 20, a limiting hole 41 is provided on one side of the limiting member 40, and the limiting member 40 can rotate along a preset axis in the mounting groove 31, and one end of the limiting connecting member 50 can pass through the mounting through hole 32 and be connected to the limiting hole 41.

[0070] Combined with Figure 5 、 Figure 6 and Figure 7 again, during installation, the mounting seat 30 is mounted on the bottom of the movable device, and there is a passage for the limiting member 40 to pass through in the part of the movable device facing the mounting groove 31, and then the limiting member 40 is inserted into the mounting groove 31 through this passage ( Figure 6 and Figure 7), at this time, the axis of the length-direction limiting hole 41 of the limiting member 40 is perpendicular.

[0071] Combined with Figure 8 , Figure 9 and Figure 10 , after the connecting seat 20 rotates 90°, the bottom plate of the movable device is clamped between the limiting member 40 and the connecting seat 20 ( Figure 9 ), so as to vertically (axially) limit the roller mechanism 10 through the limiting member 40 and the connecting seat 20, ensuring that the entire installation mechanism can provide sufficient supporting force to support the movable device. And, make the limiting hole 41 face the installation through-hole 32, and then connect the limiting connecting member 50 through the installation through-hole 32 to the limiting hole 41 ( Figure 10 ), to limit the circumferential freedom degree of the connecting seat 20, so as to quickly install the roller mechanism 10 on the movable device.

[0072] When the roller mechanism 10 needs to be disassembled, only need to first remove the limiting connecting member 50, then slightly lift the movable device upward so that there is a gap between the roller and the ground, rotate the connecting seat 20, and then move the connecting seat 20 out of the movable device. It is not necessary to lift the movable device to the height of the operable space at the bottom of the manual by a hoisting device such as a crane, avoiding the safety problems when personnel enter the bottom of the device during the roller disassembly process. And during the disassembly process, only need to disassemble the limiting connecting member 50 (the mounting seat 30 is always installed in the movable device to facilitate reconnection with the connecting seat 20), the disassembly is simple and convenient, and the disassembly efficiency of the roller is high.

[0073] In summary, the walking roller installation structure provided by this embodiment does not need to lift the movable device by a hoisting device to complete the disassembly of the roller, solves the safety problems during the roller disassembly process, and the disassembly is simple and convenient, and the disassembly efficiency of the roller is high.

[0074] Embodiment 2

[0075] Combined with Figure 1 and Figure 2 , this embodiment provides a movable device, including a device body 60, and the lower end of the device body 60 is provided with the walking roller installation structure provided by Embodiment 1. For a movable device, usually four roller mechanisms 10 are adapted, among which, the mounting frames of two roller mechanisms 10 can be fixed frames (rollers in a fixed direction), and the mounting frames of two roller mechanisms 10 are universal frames (universal wheels).

[0076] It is understandable that an installation cavity for the mounting base 30 is provided at the lower end of the device body 60. This installation cavity can be a groove and an extension plate outside the housing of the device body 60, or directly a recess at the lower end of the housing of the device body 60. In this embodiment, an installation chute 61 is provided on one side wall at the lower end of the device body 60. The installation chute 61 can allow the mounting base 30 to slide into the device body 60, so as to facilitate fixing the mounting base 30 in the device body 60 by sliding it through the installation chute 61. Combined with Figure 5 and Figure 8 , for the installation chute 61, it is also a square structure, and its cross-sectional size in a straight line is slightly larger than that of the mounting base 30.

[0077] Combined with Figure 10 , a clamping hole 62 is provided at the lower end of the device body 60. The clamping hole 62 is adapted to the limiting member 40, and the clamping hole 62 is opened on the bottom wall of the installation chute 61, so that the limiting member 40 can be inserted into the device body 60 through the clamping hole 62. While ensuring that the limiting member 40 can extend into the device body 60, the size of the clamping hole 62 is minimized as much as possible to avoid affecting the structural strength of the bottom plate of the device body 60 due to the opening of the clamping hole 62. Among them, when the limiting member 40 is inserted into the device body 60, the limiting member 40 is accommodated in the installation groove 31 to ensure that the connecting seat 20 can be connected to the mounting base 30 and the device body 60.

[0078] That is to say, for the movable device provided in this embodiment, the above-mentioned traveling roller mounting structure is provided at the lower end of the device body 60. Combined with Figure 5 , Figure 6 and Figure 7 , during installation, the mounting base 30 is installed at the bottom of the movable device, and a passage for the limiting member 40 to pass through is provided at the part of the movable device facing the installation groove 31. Then, the limiting member 40 is inserted into the installation groove 31 through this passage ( Figure 6 and Figure 7 ). At this time, the axis of the lengthwise limiting hole 41 of the limiting member 40 is perpendicular.

[0079] Combined with Figure 8 , Figure 9 and Figure 10 , after the connecting seat 20 rotates 90°, the bottom plate of the movable device is clamped between the limiting member 40 and the connecting seat 20 ( Figure 9 ), so as to vertically (axially) limit the roller mechanism 10 through the limiting member 40 and the connecting seat 20, ensuring that the entire installation mechanism can provide sufficient supporting force to support the movable device. And, make the limiting hole 41 face the installation through hole 32, and then connect the limiting connecting member 50 through the installation through hole 32 and the limiting hole 41 ([[]]END]] Figure 10), to limit the circumferential degree of freedom of the connecting seat 20, so as to quickly install the roller mechanism 10 on the movable device. Combining Figure 8 and Figure 10 , after the installation is completed, the end of the limit connecting piece 50 (screw) is located in the notch of the installation chute 61, so as to facilitate the subsequent removal of the limit connecting piece 50.

[0080] When the roller mechanism 10 needs to be disassembled, only the limit connecting piece 50 needs to be removed first, and then the movable device is slightly lifted upward so that there is a gap between the roller and the ground. Then, the connecting seat 20 is rotated, and the connecting seat 20 can be removed from the movable device. There is no need to use lifting equipment such as a crane to lift the movable device to the height of the operable space at the bottom of the manual, avoiding the safety problems that personnel enter the bottom of the device during the roller disassembly process. And during the disassembly process, only the limit connecting piece 50 needs to be disassembled, the disassembly is simple and convenient, and the disassembly efficiency of the roller is high.
