Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic loading and unloading platforms and relates to a fixed telescopic platform, in particular to a maintenance support structure and a fixed telescopic platform thereof. Background Art

[0002] The tongue plates of telescopic hydraulic loading and unloading platforms currently available in the domestic and international markets all require support during maintenance due to safety considerations. The current support structure is relatively simple, generally consisting of two square tubes or bent parts fixed to the support beams at the front end of the bottom frame. After the table is raised, the support rods on both sides are erected and inserted into the table to support the table. This support rod structure requires both sides to be inserted into the table when supporting, which is inconvenient for one person to operate. Moreover, the support rod is easily lost because it has no connection with the platform. The bottom of the support rod is often equipped with a chain that is linked to the platform to prevent the support rod from being lost. Therefore, when designing a telescopic hydraulic loading and unloading platform, it is necessary to consider the ease of use and support stability of the maintenance support structure. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a maintenance support structure and a fixed telescopic platform thereof, which solves the technical problem of how to improve the portability and support stability of the maintenance support structure on the existing fixed telescopic platform during use.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A maintenance support structure is used to support the table top during the maintenance of a fixed telescopic platform. It is characterized in that the support structure includes a fixing part and a positioning part respectively fixed on the table top and the base frame of the fixed telescopic platform. The fixing part is connected to a long strip-shaped support part that can rotate up and down. When the support part rotates downward, the support part can be plugged and unplugged with the positioning part for positioning.

[0006] The maintenance support structure of the present application is used to support the tongue plate table top on a fixed telescopic platform during maintenance. The maintenance support structure of the present application includes a fixing member and a positioning member. The fixing member is used to fix to the bottom of the tongue plate table top, and the positioning member is used to fix to the base frame. A support member is rotatably connected to the fixing member. When maintenance support is required, the support member rotates downward and plugs and unplugs with the positioning member to achieve support. During support, since the two ends of the support member are respectively connected to the fixing member and the positioning member, the force is evenly distributed and the stability is very good. When support is not needed, the support member can be rotated and retracted, which is very convenient to use and very convenient.

[0007] In the above-mentioned maintenance support structure, the fixing member is a circular tubular structure, and the fixing member is used to be fixed to the bottom of the fixed telescopic platform.

[0008] The fixing member has a circular tubular structure, which improves the structural strength and stability of the overall supporting structure and also facilitates the connection and rotation of the supporting member.

[0009] In the above-mentioned maintenance support structure, the support member includes an arc-shaped bent sheet metal and a long tube, the arc-shaped bent sheet metal includes an arc-shaped portion and two ears, one end of the long tube is fixedly connected between the two ears, and the arc-shaped bent sheet metal is rotated on the fixing member through the arc-shaped portion.

[0010] The support member main body of the present application adopts a long tube as support. The tubular structure is lighter in texture and has better anti-yield ability. Secondly, the connection between the support member and the fixing member adopts arc-shaped bent sheet metal for connection, so that the contact position area between the arc-shaped bent sheet metal and the fixing member is large, making the connection between the long tube and the fixing member more stable, and the two wide ear designs can provide better support capacity, so that the strength of the support is improved, thereby improving stability.

[0011] In the above-mentioned maintenance support structure, the distance between the two ears is close to the diameter of the fixing member, the length of the ear is greater than the radius of the fixing member, and the fixing member can move in the length direction of the two ears to adjust the position of the support member when not in use.

[0012] The distance between the two ears of the present application is close to the diameter of the fixing part, that is, the arrangement direction of the two ears can play a good role in limiting the fixing part to improve the stability during support. The length of the ear of the present application is greater than the radius of the fixing part. This design allows the fixing part and the ear to move relative to each other in the extension direction of the ear, that is, the long tube can be moved in its axial direction when not supported. When not supported, the swing end of the long tube can be hung on the hook or sheet metal on the platform by pulling and retracting the long tube to fix the position, thereby further improving the portability of the overall structure.

[0013] In the above-mentioned maintenance support structure, the positioning member is provided with a limiting portion for axially limiting the support member.

[0014] A limiting portion is also provided on the positioning member of the present application, which can limit the axial rotation direction of the support member so that the position of the support member will not shift during the support process, thereby improving stability. The positioning member can also ensure that the positions of the support member and the positioning member are always relative, so that the support member can accurately cooperate with the positioning member after rotation, thereby further improving portability.

[0015] In the above-mentioned maintenance support structure, the limiting portion is an annular groove provided on the outer peripheral surface of the fixing member, and the arc-shaped portion and / or the ear portion can form a resisting limit with the groove wall of the annular groove.

[0016] This is one of the implementation methods of the limiting portion of the present application. In this embodiment, the limiting portion is an annular groove, and the arc-shaped portion or ear can form a resistance with the groove wall of the annular groove to limit the position of the support member in the direction of the rotation axis to improve the connection stability.

[0017] In the above-mentioned maintenance support structure, the limiting portion is an angle iron, and angle irons are fixed on both sides of the support member on the outer periphery of the positioning member. The side portions of the two angle irons can form a resistance limit for the support member.

[0018] This is another embodiment of the limiting part of the present application. In this embodiment, the limiting member is an angle iron. Two angle irons are fixed on the outer periphery of the positioning member. The support member is limited between the two angle irons and can rotate but cannot move axially. This design can achieve the same technical effect as the above-mentioned scheme.

[0019] In the above-mentioned maintenance support structure, the two ends of the fixing member are respectively fixed between two reinforcing ribs of the fixed telescopic platform table, and the angle irons are all horizontally oriented and fixed on the side of the table beam of the fixed telescopic platform.

[0020] One end of the angle iron of the present application is fixed to the fixing piece, and the other end is fixed to the side of the beam on the platform. The angle iron designed in this way can not only limit the support piece and improve stability, but also improve the fixing strength between the fixing piece and the platform, thereby improving the support strength to further improve the overall support stability.

[0021] In the above-mentioned maintenance support structure, the positioning member is a fixed shaft, which is vertically fixed on the base frame of the fixed telescopic platform and is positioned relative to the support member. The diameter of the fixed shaft is smaller than the inner diameter of the long tube.

[0022] The diameter of the fixed shaft is smaller than the inner diameter of the long tube instead of just fitting it. This design allows the long tube to be plugged in and out of the fixed shaft when tilted, maintaining the tilted support state and providing better support stability.

[0023] A fixed telescopic platform, characterized in that it includes a base frame, a platform, a lifting mechanism and the above-mentioned maintenance support structure, the lifting mechanism is fixed on the base frame, the platform is fixed on the lifting mechanism and is driven to rise or fall in the vertical direction by the lifting mechanism, the bottom of the platform has a plurality of reinforcing ribs arranged at intervals in its length direction, the bottom of the platform has cross beams on both sides in its width direction, the two ends of the above-mentioned fixing part are respectively welded to two adjacent reinforcing ribs, and the above-mentioned two angle irons are respectively welded to the side of the cross beam, and the positioning part is fixed on the base frame below the support part.

[0024] Beneficial effects of the utility model:

[0025] 1. When maintenance support is needed, the support part is rotated downward and matched with the positioning part to achieve support. During support, since the two ends of the support part are respectively connected to the fixing part and the positioning part, the force is evenly distributed and the stability is very good. When support is not needed, the support part can be rotated and retracted, which is very convenient to use and very convenient.

[0026] 2. One end of the angle iron of the limiting member of the present application is fixed to the fixing member, and the other end is fixed to the side of the beam on the platform. The angle iron designed in this way can not only limit the support member to improve stability, but also improve the fixing strength between the fixing member and the platform, thereby improving the support strength to further improve the overall support stability.

[0032] Example 1

[0033] like Figures 1-4A maintenance support structure shown is used to support the tabletop during the maintenance of a fixed telescopic platform. This support structure includes a fixing member 1 and a positioning member 2 fixed to the tabletop and the base frame of the fixed telescopic platform, respectively. The fixing member 1 is a circular tubular structure and is used to be fixed to the bottom of the fixed telescopic platform. The fixing member 1 is connected to a long strip-shaped support member 3 that can rotate up and down. The positioning member 2 is a fixed shaft that is vertically fixed to the base frame of the fixed telescopic platform and the position of the fixed shaft is set relative to the position of the support member 3. When the support member 3 rotates downward, the support member 3 can be plugged and unplugged with the positioning member 2 for positioning. The maintenance support structure of the present application is used to support the tongue plate tabletop on the fixed telescopic platform during maintenance. The maintenance support structure of the present application includes a fixing member 1 and a positioning member 2. The fixing member 1 is used to fix to the bottom of the tongue plate table, and the positioning member 2 is used to fix to the base frame. A support member 3 is rotatably connected to the fixing member 1. When maintenance support is required, the support member 3 is rotated downward and plugged into and unplugged with the positioning member 2 to achieve support. During support, since the two ends of the support member 3 are respectively connected to the fixing member 1 and the positioning member 2, the force is evenly distributed and the stability is very good. When support is not needed, the support member 3 can be rotated and retracted. It is very convenient to use and has good convenience. The fixing member 1 is a circular tubular structure, which makes the structural strength and stability of the overall support structure better, and also facilitates the connection and rotation of the support member 3.

[0034] Furthermore, the specific structure of the support member 3 is as follows: the support member 3 includes an arc-shaped bent sheet metal 32 and a long tube 31. The arc-shaped bent sheet metal 32 includes an arc-shaped portion 321 and two ears 322. One end of the long tube 31 is fixedly connected between the two ears 322. The arc-shaped bent sheet metal 32 is mounted on the fixing member 1 through the arc-shaped portion 321 for rotation. The main body of the support member 3 of the present application adopts the long tube 31 as a support. The tubular structure is lighter in texture and has better yield resistance. Secondly, the connection between the support member 3 and the fixing member 1 is connected by the arc-shaped bent sheet metal 32, so that the contact area between the arc-shaped bent sheet metal 32 and the fixing member 1 is large, making the connection between the long tube 31 and the fixing member 1 more stable. In addition, the design of the two wide ears 322 can provide better support capacity, thereby improving the strength of the support and thus improving stability.

[0035] Preferably, the distance between the two ears 322 is close to the diameter of the fixing member 1, and the length of the ears 322 is greater than the radius of the fixing member 1. The fixing member 1 can move in the length direction of the two ears 322 to adjust the position of the support member 3 when not in use. The distance between the two ears 322 of the present application is close to the diameter of the fixing member 1, that is, the arrangement direction of the two ears 322 can play a good role in limiting the fixing member 1 to improve the stability during support. The length of the ears 322 of the present application is greater than the radius of the fixing member 1. This design allows the fixing member 1 and the ears 322 to move relative to each other in the extension direction of the ears 322, that is, the long tube 31 can move in its axial direction when not supporting. When not supporting, the long tube 31 can be pulled out and extended to allow the swing end of the long tube 31 to be hooked with the hook or sheet metal on the platform to achieve fixed position, thereby further improving the portability of the overall structure.

[0036] Furthermore, the positioning member 2 is provided with a limiting portion 4 for axially limiting the support member 3. The limiting portion 4 is an angle iron 41. An angle iron 41 is fixed on both sides of the support member 3 on the outer periphery of the positioning member 2. The side portions of the two angle irons 41 can form a resistance limit for the support member 3. The positioning member 2 of the present application is also provided with a limiting portion 4. The limiting portion 4 can limit the axial rotation direction of the support member 3, so that the position of the support member 3 will not shift during the support process, thereby improving stability. Moreover, the positioning member 2 can also keep the positions of the support member 3 and the positioning member 2 relative to each other at all times, so that the support member 3 can accurately cooperate with the positioning member 2 after rotation, further improving portability. In this embodiment, the limiting member is an angle iron 41. Two angle irons 41 are fixed on the outer periphery of the positioning member 2. The support member 3 is limited between the two angle irons 41 and can rotate but cannot move axially. Such a design can improve stability.

[0037] Furthermore, the two ends of the fixing member 1 are respectively fixed between two reinforcing ribs on the fixed telescopic platform tabletop, and the angle irons 41 are all horizontally oriented and fixed to the side of the crossbeam of the fixed telescopic platform tabletop. One end of the angle iron 41 of the present application is fixed to the fixing member 1, and the other end is fixed to the side of the crossbeam on the platform. This design of the angle iron 41 can not only limit the support member 3 and improve stability, but also improve the fixing strength between the fixing member 1 and the platform, thereby improving the support strength and further improving the overall support stability.

[0038] Furthermore, the diameter of the fixed shaft is smaller than the inner diameter of the long tube 31. The diameter of the fixed shaft is smaller than the inner diameter of the long tube 31 rather than just fitting, so that the long tube 31 can be plugged and unplugged with the fixed shaft when tilted, maintaining the tilted support state and improving the support stability.

[0039] A fixed telescopic platform includes a base frame, a platform, a lifting mechanism and the above-mentioned maintenance support structure. The lifting mechanism is fixed to the base frame, the platform is fixed to the lifting mechanism and is driven to rise or fall in the vertical direction by the lifting mechanism. The bottom of the platform has a plurality of reinforcing ribs arranged at intervals in its length direction, and the bottom of the platform has cross beams on both sides in its width direction. The two ends of the above-mentioned fixing part 1 are respectively welded to two adjacent reinforcing ribs, and the two angle irons 41 are respectively welded to the sides of the cross beam. A positioning part 2 is fixed on the base frame below the support part 3.

[0040] Example 2

[0041] This is one of the implementations of the limiting portion 4 of the present application. In this embodiment, the other structures are basically the same as those in Example 1, except that: the limiting portion 4 in this embodiment is an annular groove, and the arc-shaped portion or ear 322 can form a resistance with the groove wall of the annular groove to limit the position of the support member 3 in the direction of the rotation axis to improve the connection stability.
