[0029] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the structure of an idler roller replacement auxiliary device according to an exemplary embodiment of this application. (Reference) Figure 1 It can be seen that the idler roller replacement auxiliary device may include:
[0030] Support mechanisms 110 are respectively disposed on both sides of the upper idler roller assembly 230. From bottom to top, each support mechanism 110 includes a second fixing member 113, a jack 112, and a first fixing member 111. The second fixing member 113 is mounted on the belt support 210, and the jack 112 is mounted on the second fixing member 113. The output end 112a of the jack 112 is connected to the first fixing member 111. The first fixing member 111, the jack 112, and the second fixing member 113 can be connected by welding or other methods; this embodiment does not limit the specific connection methods described herein.
[0031] The upper support rod 120 is suspended above the upper idler roller assembly 230. Both ends of the upper support rod 120 are respectively mounted on the first fixing members 111 on both sides of the upper idler roller assembly 230. The upper support rod 120 is used to drive the upper belt 220 away from the upper idler roller assembly 230 under the drive of the support mechanism 110. That is, the upper support rod 120 can drive the upper belt 220 away from the idler roller assembly 230 under the drive of the jack 112.
[0032] For example, when using the roller replacement auxiliary device provided in the embodiments of this application, the two support mechanisms 110 can be fixed to the belt bracket 210 by the second fixing member 113. Then, the upper support rod 120 can be passed through the lower end of the upper belt, and one end of the upper support rod 120 can be connected to the first fixing member 111 of one support mechanism 110, and the other end of the upper support rod 120 can be connected to the first fixing member 111 of another support mechanism 110. Then, two jacks 112 can be used to lift the upper belt 220 by lifting the upper support rod 120, thereby replacing the rollers in the upper roller group 230.
[0033] Please refer to Figure 2 This is a schematic diagram illustrating the structure of a roller replacement auxiliary device, which is another exemplary embodiment of this application. (See reference...) Figure 2 It can be seen that the upper support rod 120 in the idler roller replacement auxiliary device may include a ring sleeve 121 and connectors 122 disposed at both ends of the ring sleeve. At least one connector 122 is movably connected to the ring sleeve 121, and the end of the connector 122 away from the ring sleeve 121 is respectively installed on the first fixing member 111. The movable connection is also a detachable connection.
[0034] It should be noted that at least one connector 122 is movably connected to the ring 121 to facilitate adjustment of the width of the upper support rod 120 according to the width of the upper belt. One connector 122 may be movably connected to the ring 121, while the other connector 122 may be fixedly connected to the ring 121. Alternatively, both connectors 122 may be movably connected to the ring 121.
[0035] In one embodiment of this application, the second fixing member 113 may include a first blocking member 113a disposed in a first direction and a second blocking member 113b disposed in a second direction, the first direction being perpendicular to the second direction, and the first blocking member 113a being connected to the second blocking member 113b.
[0036] In one embodiment of this application, the jack 112, the first blocking member 113a and the second blocking member 113b constitute a placement space, and the belt bracket 210 can be located in the placement space.
[0037] In one embodiment of this application, the idler roller replacement auxiliary device may further include a lower support rod 130 for supporting the lower belt 240, with both ends of the lower support rod 130 respectively mounted on the second fixing member 113. Figure 2 (Unmarked)
[0038] Please refer to Figure 3 , it is Figure 2The diagram shows the structure of the upper support rod in the idler roller replacement auxiliary device. The upper support rod may include a bearing part a, which matches the shape of the upper belt. The bearing part a of the upper support rod can prevent the upper belt 220 from slipping during the lifting of the upper belt 220.
[0039] For example, the upper support rod can be a U-shaped structure.
[0040] In one embodiment of this application, at least one connector 122 is provided with a buckle b for connecting with a ring sleeve 121, and the ring sleeve 121 is provided with a fixing position c for buckle limiting.
[0041] It should be noted that the buckle b can be an elastic element so that one end of the connector 122 with the buckle b is connected to the ring 121.
[0042] Please refer to Figure 4 , it is Figure 2 The diagram shows the structure of the support mechanism in the roller replacement auxiliary device.
[0043] First fastener 111 ( Figure 4 The upper support rod (not marked) is provided with a placement part 111a, and both ends of the upper support rod are placed in the placement part 111a. This provides more stable and secure support for the upper support rod. The placement part 111a makes the use of the idler roller changing auxiliary device safer and more reliable in various environments, such as on inclined conveyor belts.
[0044] It should be noted that the size of the placement part 111a can be set to be slightly larger than the width of one end of the upper support rod so that the connector 122 will not fall off when the upper belt is lifted using the roller replacement auxiliary device provided in this application embodiment.
[0045] In one embodiment of this application, a first limiting member for limiting the upper support rod is further installed on the first fixing member 111. The first limiting member is used to limit the installation position of the upper support rod on the first fixing member. The width of the first limiting member may be greater than the width of the placement part 111a, and the first limiting member may be provided with threads. The end of the upper support rod connected to the first fixing member may be provided with threads that cooperate with the first limiting member.
[0046] It should be noted that when the first fixing member 111 is connected to the upper support rod 120, the upper support rod is limited by the first limiting member, which can prevent the upper support rod 120 from falling off when the upper belt is lifted.
[0047] For example, the first blocking member 113a may be provided with a fixing hole 113c, and the second blocking member 113b is connected to the fixing hole 113c. The first blocking member 113a and the second blocking member 113b can be movably connected. The second blocking member 113b may be a variable diameter structure to facilitate the removal and placement of the second blocking member 113b.
[0048] In one embodiment of this application, the second blocking member 113b may be threadedly connected to the first blocking member 113a.
[0049] In one embodiment of this application, the first blocking member 113a is provided with a placement hole d.
[0050] exist Figure 2 In the roller replacement auxiliary device shown, the lower support rod 130 is provided with a second limiting member 131 at both ends for limiting the lower support rod 130. The second limiting member 131 is used to limit the lower support rod 130 at the installation position of the placement hole d.
[0051] For example, when using the roller replacement auxiliary device provided in this application embodiment, the jack 122 can first fix two support structures in the initial position. When fixing the support structure, the support structure can be first erected on the belt bracket 210. At this time, the two first blocking members 113a set in the first direction are located on both sides of the belt bracket 210. Then, the second blocking member 113b can be used to pass through the two fixing holes 113c to complete the fixing of the support structure. The connector 122 is connected to the ring 121, and the position of the buckle b is adjusted according to the width of the upper belt. The upper support rod 120 is passed through the lower end of the upper belt, and one end of the upper support rod 120 extends out of the placement hole 111a of one support structure. The one end of the upper support rod 120 is fixed by the blocking member, and the other end of the upper support rod 120 extends out of the placement hole 111a of another support structure. The other end of the upper support rod 120 is fixed by the blocking member. Then, the two jacks 112 can be used to lift the upper belt 220 by lifting the upper support rod 120, thereby replacing the upper roller 230.
[0052] For example, after fixing the two support structures to the belt bracket 210, the lower support rod 130 can be passed through the lower belt 240 and placed in the placement holes d of the two first blocking members 113a. At this time, the second limiting member 131 is located on the side of the placement hole d away from the lower idler group, preventing the lower support rod 130 from sliding off when the lower belt is lifted. After connecting the lower support rod 130 to the second fixing member 113, the lower idler group 250 can be replaced. When replacing idlers using the idler replacement auxiliary device provided in this application embodiment, the idlers of both the upper and lower idler groups can be replaced, reducing manpower and operational intensity, and allowing for quick and safe replacement of transport belt idlers.
[0053] It should be noted that the upper and lower support rods can be made of steel. The lower support rod can also adopt the same structure as the upper support rod, with a ring, buckle, and fixing position (for buckle limiting), to adjust the length of the lower support rod.
[0054] In summary, the solution of this application embodiment, by setting up a support mechanism and an upper support rod, has the support mechanism respectively set on both sides of the upper idler roller group. The support mechanism includes, from bottom to top, a second fixing member, a jack, and a first fixing member. The second fixing member is used to be installed on the belt bracket, and the jack is installed on the second fixing member. The output end of the jack is connected to the first fixing member. The upper support rod is suspended above the upper idler roller group, and both ends of the upper support rod are respectively installed on the first fixing members on both sides of the upper idler roller. The upper support rod is used to drive the upper belt away from the upper idler roller group under the drive of the support mechanism. In use, the upper belt is located on the upper support rod, and the upper belt can be moved by the jack and fixed in a suitable position, which makes it convenient for operators to replace the idlers in the upper idler roller group, reduces the difficulty of replacing idlers, and improves the safety when replacing idlers.
[0055] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
