Description

Technical Field

[0001] The utility model relates to the technical field of connection of maintenance platforms, in particular to a connection structure between a tread plate and a steel beam of a maintenance platform. Background Technique

[0002] A maintenance platform is a temporary construction project used for equipment maintenance and repair. It is usually built around the equipment to provide a safe working space for maintenance personnel. The maintenance platform is usually composed of a steel beam support frame and a tread plate. The tread plate is connected to the steel beam support frame through a connecting piece. For some connection structures, including T-shaped connection seats, when connecting the tread plate and the steel beam of the maintenance platform, first, the T-shaped connection seat is fixed to the corresponding position on the steel beam through bolts, and then the tread plate is placed into the installation groove formed by two horizontally adjacent connection seats. Subsequently, the tread plate is fixed to the T-shaped connection seat through bolts, thus realizing the connection and installation of the tread plate and the steel beam. However, there are errors in the production process of the tread plate itself. If the horizontal dimension of the tread plate is not equal to the installation groove formed by two horizontally adjacent connection seats, it will cause the threaded holes between the T-shaped connection seat and the tread plate to be misaligned, resulting in the unusability of the tread plate. Moreover, the usage environment of the tread plate of the maintenance platform is complex. To improve safety, damaged tread plates need to be replaced in time. However, the device uses multiple groups of bolts to install and limit the tread plate of the maintenance platform. During the replacement process of the tread plate, the bolts need to be removed one by one and then installed one by one, and the operation is relatively cumbersome. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a connection structure between a tread plate and a steel beam of a maintenance platform. The device can connect and install a tread plate with a slight horizontal dimension error to the steel beam through an elastic extrusion element, which is convenient to use. At the same time, the device uses an elastic plugging element to install and limit the tread plate of the maintenance platform, and the later replacement operation of the tread plate is convenient and fast, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A connection structure between a tread plate and a steel beam of a maintenance platform, including a steel beam frame;

[0005] Steel beam frame: There are two of them. Uniformly distributed connecting seats are installed on the opposite inner sides of the two steel beam frames. A tread plate is placed between two laterally adjacent connecting seats. On one wall of each connecting seat away from the center of the tread plate, an extrusion seat is provided through uniformly distributed telescopic columns. Slots are opened at the upper ends of the extrusion seats, and vertical movement limiting seats are inserted into the slots. The vertical movement limiting seats and the extrusion seats are both installed in cooperation with the adjacent tread plates. Through elastic extrusion elements, this device enables the connection and installation of tread plates with slight lateral dimension errors to the steel beam, which is convenient to use. At the same time, through elastic insertion elements, the tread plates of the maintenance platform are installed and limited, and the replacement operation of the tread plates in the later stage is convenient and fast.

[0006] Further, uniformly distributed first springs are provided between each extrusion seat and the adjacent connecting seat. The first springs are all movably sleeved on the outer ends of the adjacent telescopic columns. Through the compression elastic force of the first springs, the extrusion seats are in adaptive elastic contact with the sides of the tread plates of the maintenance platform.

[0007] Further, longitudinal movement clamping seats are provided on the top walls of the vertical movement limiting seats. Uniformly distributed card slots are opened on the upper sides of the tread plates. The longitudinal movement clamping seats are all inserted into the adjacent card slots to limit the longitudinal movement connection of the tread plates of the maintenance platform.

[0008] Further, uniformly distributed locking columns are slidably connected inside each extrusion seat. Uniformly distributed locking holes are opened at the lower ends of the vertical movement limiting seats. The locking columns are all inserted into the adjacent locking holes to limit the vertical movement connection of the tread plates of the maintenance platform.

[0009] Further, a dial plate is also included. The dial plates are all arranged between two longitudinally adjacent locking columns. Uniformly distributed second springs are provided between the dial plates and the adjacent extrusion seats. The second springs are all movably sleeved on the outer sides of the adjacent locking columns. Through the tensile elastic force of the second springs, the phenomenon that the locking columns slip back from the adjacent locking holes is avoided.

[0010] Further, uniformly distributed reinforcing ribs are provided at the lower ends of the connecting seats to improve the load-bearing capacity of the device for the tread plates.

[0011] Further, rubber pads are provided on one side of each extrusion seat close to the center of the tread plate. By increasing the contact friction force, the phenomenon of sliding between the tread plates of the maintenance platform and the connecting seats is reduced.

[0012] Compared with the prior art, the beneficial effects of the present utility model are: The connection structure between the tread plates of this maintenance platform and the steel beam has the following advantages:

[0013] 1. When connecting and installing the treads and steel beams of the inspection platform, first fix the connecting seats to the corresponding positions on the steel beams by bolts, and then align the treads vertically downward and place them between two laterally adjacent connecting seats. During this process, the lower edges of the left and right ends of the treads contact with the corresponding extrusion seats, the extrusion seats are compressed, and the telescopic ends of the telescopic columns and spring 1 elastically contract. Through the compression force of spring 1, the extrusion seats are in close contact with the adjacent treads to avoid a contact gap between the two, so that treads with slight lateral dimensional errors can also be installed and connected for use. The connection structure between the treads and steel beams of the inspection platform uses elastic extrusion elements, so that the device can connect and install treads with slight lateral dimensional errors to the steel beams, which is easy to use.

[0014] 2. When connecting and installing the treads and steel beams of the inspection platform, the treads are limited in transverse movement through the extrusion seat. The rubber pad increases the contact friction to avoid relative sliding between the treads and the adjacent extrusion seats. The paddle is moved to drive the locking column to move to the end away from the center of the device. The spring is elastically stretched, and then the vertical limit seat is inserted into the corresponding slot. In this process, the longitudinal limit seat is connected with the slot on the tread to limit the longitudinal movement of the tread. When the vertical limit seat After being fully inserted into the slot, the locking hole is horizontally aligned with the adjacent locking column, and then the force applied to the paddle plate is released. The locking column is plugged into the adjacent locking hole through the stretching elastic force of spring 2, and the tread is vertically limited, thereby achieving rapid installation of the tread, and convenient for disassembly and replacement of a damaged tread at a later time. The connection structure between the tread and the steel beam of the maintenance platform uses elastic plug-in elements to limit the installation of the tread of the maintenance platform, and the tread replacement operation is convenient and quick at a later time.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , this embodiment provides a technical solution: a connection structure between a tread plate and a steel beam of an inspection platform, including a steel beam frame 1;

[0021] Steel beam frame 1: There are two of them. Uniformly distributed connection seats 2 are installed on the opposite inner sides of the two steel beam frames 1. A tread plate 3 is placed between two adjacent connection seats 2 in the horizontal direction. On one wall of the connection seat 2 away from the center of the tread plate 3, a pressing seat 6 is provided through uniformly distributed telescopic columns 4. Slots 7 are opened at the upper ends of the pressing seats 6. Vertical movement limiting seats 8 are inserted into the interiors of the slots 7. The vertical movement limiting seats 8 and the pressing seats 6 are both cooperatively installed with the adjacent tread plates 3. Uniformly distributed first springs 5 are provided between the pressing seats 6 and the adjacent connection seats 2. The first springs 5 are all movably sleeved on the outer ends of the adjacent telescopic columns 4. When using the device to connect and install the tread plate 3 and the steel beam frame 1 of the inspection platform, first, the connection seats 2 are respectively fixed to the corresponding positions on the steel beam frame 1 through bolts. Subsequently, the tread plate 3 is vertically aligned and placed between two adjacent connection seats 2 in the horizontal direction. During this process, the lower edges of the left and right ends of the tread plate 3 come into contact with the corresponding pressing seats 6. The pressing seats 6 are pressed, and the telescopic ends of the telescopic columns 4 and the first springs 5 elastically contract. Through the compression elastic force of the first springs 5, the pressing seats 6 are made to be in close contact with the adjacent tread plates 3, avoiding the occurrence of contact gaps between the two, so that the tread plates 3 with slight lateral dimension errors can also be installed and connected for use. The connection structure between the tread plate 3 and the steel beam of this inspection platform enables the device to connect and install the tread plate 3 with slight lateral dimension errors to the steel beam through elastic pressing elements, which is convenient to use;

[0022] Among them, longitudinal movement clamping seats 9 are provided on the top walls of the vertical movement limit seats 8, evenly distributed card slots are formed on the upper sides of the tread plates 3, and the longitudinal movement clamping seats 9 are inserted into the adjacent card slots. A plurality of locking columns 10 are slidably connected inside the extrusion seats 6, a plurality of locking holes 13 are formed at the lower ends of the vertical movement limit seats 8, and the locking columns 10 are inserted into the adjacent locking holes 13. It further includes a dial plate 12, the dial plates 12 are arranged between two longitudinally adjacent locking columns 10, a plurality of second springs 11 are provided between the dial plates 12 and the adjacent extrusion seats 6, and the second springs 11 are movably sleeved on the outer sides of the adjacent locking columns 10. Reinforcing ribs 14 are evenly provided at the lower ends of the connecting seats 2, and rubber pads 15 are provided on one side of the extrusion seats 6 close to the center of the tread plate 3. When the device is used to connect and install the tread plate 3 and the steel beam frame 1 of the maintenance platform, the rubber pad 15 increases the contact friction force to prevent relative sliding between the tread plate 3 and the adjacent extrusion seat 6 at this time. Then, the dial plate 12 is toggled to drive the locking column 10 to move towards the end far from the center of the device, and the second spring 11 is elastically stretched. Then, the vertical movement limit seat 8 is inserted into the corresponding slot 7. During this process, the longitudinal movement clamping seat 9 is inserted into the card slot on the tread plate 3 to longitudinally limit the tread plate 3. When the vertical movement limit seat 8 is completely inserted into the slot 7, the locking hole 13 is horizontally aligned with the adjacent locking column 10. Then, the force applied to the dial plate 12 is released, and the locking column 10 is inserted into the adjacent locking hole 13 through the tensile elastic force of the second spring 11, thereby vertically limiting the tread plate 3, so as to realize the rapid installation of the tread plate 3. In the later stage, the disassembly and replacement operation of a damaged tread plate 3 is convenient. The tensile elastic force of the second spring 11 is used to prevent the locking column 10 from being inserted and separated from the corresponding locking hole 13 during the use of the maintenance platform. The support strength of the connecting seat 2 is improved through the reinforcing rib 14, and then the load-bearing capacity of the tread plate 3 of the maintenance platform itself is improved. The connection structure between the tread plate and the steel beam of the maintenance platform uses elastic insertion elements to install and limit the tread plate 3 of the maintenance platform, and the replacement operation of the tread plate 3 in the later stage is convenient and fast.

[0023] When the stepping plate 3 and the steel beam frame 1 are connected, the connecting seat 2 is fixed to the corresponding position on the steel beam frame 1 by bolts, and then the stepping plate 3 is vertically aligned downward and placed between two laterally adjacent connecting seats 2. During this process, the lower edges of the left and right ends of the stepping plate 3 are in contact with the corresponding extrusion seats 6, the extrusion seats 6 are compressed, and the telescopic ends of the telescopic columns 4 and the spring 1 5 are elastically contracted. Through the compression elastic force of the spring 1 5, the extrusion seats 6 are in close contact with the adjacent stepping plates 3 to avoid a contact gap between the two, so that the stepping plates 3 with slight lateral size errors can also be installed and connected for use. The rubber pad 15 increases the contact friction to avoid relative sliding between the stepping plate 3 and the adjacent extrusion seats 6 at this time. Then, the dial plate 12 is toggled to drive the locking column 10 to When the locking rib 14 is released, the locking column 10 is engaged with the adjacent locking hole 13, and the stepping plate 3 is vertically limited, thereby realizing the rapid installation of the stepping plate 3, and the disassembly and replacement of a damaged stepping plate 3 is convenient in the later stage. The stretching elastic force of the spring 2 11 is utilized to avoid the plug-in separation of the locking column 10 and the corresponding locking hole 13 during the use of the maintenance platform, and the supporting strength of the connecting seat 2 is improved by the reinforcing rib 14, thereby improving the bearing capacity of the stepping plate 3 of the maintenance platform.
