[0042] The following combination Figures 1-8 The technical solution of the utility model is further illustrated through specific implementation methods.

[0043] The present invention provides a work platform comprising a platform body 1 and a support assembly 2, wherein the top wall 11 of the platform body 1 is recessed with an open accommodating cavity; the support assembly 2 comprises a support rod assembly, a first connecting member 22, and a fastener, one end of the support rod assembly being slidably mounted on the platform body 1 in a direction perpendicular to the platform body 1, the support rod assembly being provided with a plurality of pin holes 211 spaced apart along the sliding direction of the support rod assembly, the first connecting member 22 being selectively inserted into one of the pin holes 211, and the fastener enabling the first connecting member 22 to be detachably connected to the platform body 1. Specifically, one end of the support rod assembly is slidably mounted on the platform body 1, and during use, the position of the support rod assembly relative to the platform body 1 is adjusted according to the working conditions on site. After the relative position of the support rod assembly and the platform body 1 is determined, the first connecting member 22 is inserted into the pin hole 211 closest to the platform body 1 among the plurality of pin holes 211, and then secured with the fastener to complete the fixed connection between the support rod assembly and the platform body 1. The work platform has a simple structure, is easy to install and disassemble, and the height of the platform body 1 is easy to adjust. When there are multiple support rod groups, the position of each support rod group relative to the platform body 1 can be adjusted individually, so that the work platform can be placed on uneven ground. The platform body 1 is provided with a storage cavity with an opening. After the work platform is used, the platform body 1 is turned upside down with the opening facing upward, and the parts can be stored in the storage cavity. During the overhaul of the nuclear power unit, when the quick-release sealing assembly of the pressure vessel top in the reactor pit is disassembled and assembled, this setting facilitates the lifting of the entire work platform. It should be noted that this embodiment does not specifically limit the number of support rod groups, and it can be set according to the usage situation.

[0044] Furthermore, the platform body 1 includes a top wall 11 and side walls. The side walls are arranged on the top wall 11 along the circumference of the top wall 11. The top wall 11 and the side walls form a receiving cavity. The receiving cavity can accommodate parts on the working platform, such as support components, thereby avoiding the risk of parts being left behind. In this embodiment, the platform body 1 is made of aluminum alloy material, which has good corrosion resistance and light texture, and can effectively reduce the overall weight of the working platform. Optionally, the top wall 11 of the platform body 1 adopts a hollow structure, which further reduces the weight of the working platform. A second mounting hole 111 is provided on the top wall 11, and the support rod group is inserted into the second mounting hole 111. The support rod group can slide along the extension direction of the second mounting hole 111. The provision of the second mounting hole 111 can facilitate the assembly and disassembly of the support rod group.

[0045] Furthermore, a fifth through hole 221 is provided on the first connecting member 22, and a fastener is provided through the fifth through hole 221, thereby fixing the first connecting member 22 to the top wall 11. Preferably, two fifth through holes 221 are provided. After the first connecting member 22 is inserted into the pin hole 211, the two fifth through holes 221 are respectively located on both sides of the pin hole 211, which can improve the stability of the connection between the support rod group and the platform body 1. In this embodiment, the fastener includes a bolt and a nut corresponding to the bolt. The first connecting member 22 is located on the lower surface side of the top wall 11, the bolt is provided through the fifth through hole 221, the bolt and the nut are screwed together, and the nut abuts against the upper surface side of the top wall 11, thereby fixing the first connecting member 22 to the platform body 1. Alternatively, the first connecting member 22 is located on the upper surface side of the top wall 11, the bolt is provided through the fifth through hole 221, the bolt and the nut are screwed together, and the nut abuts against the lower surface side of the top wall 11.

[0046] In order to make the working platform applicable to different working conditions, such as Figure 4 As shown, the support assembly 2 also includes a plurality of adjustment members 23. The support rod group includes a plurality of support members 21, which are arranged in sequence along the sliding direction of the support rod group. The adjustment members 23 can securely connect two adjacent support members 21 end to end. If the working platform is not high enough during use, the adjustment members 23 can be used to connect two support members 21, thereby increasing the height of the working platform and making it more applicable.

[0047] Furthermore, a second fixing pin 231 is provided on the adjusting member 23, a first connecting hole is provided on the supporting member 21, and a second connecting hole is provided on the adjusting member 23. When the supporting member 21 is inserted into the adjusting member 23, the first connecting hole and the second connecting hole are opposite to each other. The second fixing pin 231 is passed through the first connecting hole and the second connecting hole, so that the supporting member 21 and the adjusting member 23 are relatively fixed, thereby increasing the usable height of the platform.

[0048] Furthermore, if Figure 5As shown, the support assembly 2 also includes a support base 24, which can enhance the stability of the support platform. Specifically, the support base 24 includes a sleeve 241 and a support plate 242. The sleeve 241 is fixed to the support plate 242 and is used to connect to the support rod assembly. The axis of the sleeve 241 is perpendicular to the support plate 242. Along the axis of the sleeve 241, the projection of the sleeve 241 is located within the support plate 242. That is, the cross-sectional dimensions of the support plate 242 are larger than the cross-sectional dimensions of the sleeve 241. This arrangement enhances the stability of the support base 24. Furthermore, the other end of the support rod assembly is plugged into the sleeve 241 and is detachably connected to the sleeve 241. In this embodiment, the support seat 24 also includes a first fixing pin 243, and the other end of the support rod group is provided with a first through hole 212, and the sleeve 241 is provided with a second through hole 2411. When the other end of the support rod group is inserted into the sleeve 241, the first through hole 212 and the second through hole 2411 are opposite to each other, and the first fixing pin 243 is passed through the first through hole 212 and the second through hole 2411, thereby connecting the support seat 24 with the support rod group. The use of the first fixing pin 243 makes it easy to disassemble the support seat 24 and the support rod group.

[0049] In order to increase the usable area of ​​the work platform and prevent parts from being scattered during transportation, in this embodiment, two platform bodies 1 are provided, and the two platform bodies 1 have a first state and a second state. Specifically, one side wall of the platform body 1 is configured as an abutment wall 12. In the first state, the two abutment walls 12 abut against each other, and after the two platform bodies 1 are relatively fixed, the top walls 11 of the two platform bodies 1 are coplanar, thereby increasing the usable area of ​​the work platform; in the second state, the openings of the two platform bodies 1 face each other, and after the two platform bodies 1 are relatively fixed, the accommodating cavities of the two platform bodies 1 are enclosed as a closed cavity. After the parts on the work platform are disassembled, they are placed in the cavity, which can prevent the parts from being scattered and lost, and also facilitate the overall transportation of the work platform.

[0050] In other embodiments, the number of platform bodies 1 can be multiple, and the specific number is selected according to the on-site working conditions. When in use, two adjacent platform bodies 1 are connected, and the number of support components 2 is set according to the platform body 1 to ensure the stability of the platform body 1.

[0051] Furthermore, the work platform further includes a second connecting member 3, and a first mounting hole 121 is provided on the abutting wall 12 of the platform body 1. When the two platform bodies 1 are in the first state, the two first mounting holes 121 are arranged opposite to each other, and the two ends of the second connecting member 3 are respectively passed through the two first mounting holes 121 on the two platform bodies 1 to connect the two platform bodies 1. In this embodiment, Figure 7As shown, the working platform also includes a fixing member 4, and the second connecting member 3 is located on both sides of the two abutting walls 12 and is respectively provided with a third through hole 31, and a fourth through hole 13 is provided on the side wall of the accommodating cavity adjacent to the abutting wall 12 on the platform body 1. The fourth through hole 13 is connected to the first mounting hole 121 and is opposite to the third through hole 31 of the second connecting member 3 in the corresponding first mounting hole 121. The axis of the fourth through hole 13 is set at an angle to the axis of the first mounting hole 121. The fixing member 4 is sequentially passed through the third through hole 31 and the fourth through hole 13 to fix the second connecting member 3 to the two platform bodies 1 respectively, so that the top walls 11 of the two platform bodies 1 are coplanar, so that the two platform bodies 1 can be spliced ​​and used.

[0052] Furthermore, when the two platform bodies 1 are in the second state, in order to make the two platform bodies 1 relatively fixed, thereby facilitating the overall transportation of the work platform, in this embodiment, the work platform also includes a buckle 5, which is arranged on the side wall of the platform body 1. After the work platform is used, one platform body 1 is inverted so that its opening is facing upward, and the support rod group and other components are placed in the accommodating cavity of the platform body 1, and the other platform body 1 is placed on the inverted platform body 1 to realize that the accommodating cavities of the two platform bodies 1 are enclosed in a closed cavity, and then the buckle 5 is used to fix the two platform bodies 1 to transport the work platform as a whole.

[0053] In order to improve the safety of users, the working platform also includes a guardrail 6, which is set on the top wall 11 and is arranged along the circumference of the top wall 11 to ensure the safety of use. Furthermore, a base 112 is set on the top wall 11, and the guardrail 6 can be plugged into the base 112, which facilitates the installation and removal of the guardrail 6. Figure 8 As shown, a sixth through hole 1121 is provided on the base 112, and a seventh through hole 61 is provided on the guardrail 6. When the guardrail 6 is inserted into the base 112, the sixth through hole 1121 is opposite to the seventh through hole 61, and then the third fixing pin 62 is sequentially passed through the sixth through hole 1121 and the seventh through hole 61, thereby fixing the guardrail 6 on the platform body 1, further improving the safety of the use of the work platform.

[0054] The following describes in detail the method for using the work platform provided in this embodiment, taking the work platform including two platforms as an example:

[0055] First, open the buckle 5, separate the two platform bodies 1 placed opposite each other, and take out the parts placed in the accommodating cavity; use the second connecting member 3 to pass through the first mounting holes 121 on the two platform bodies 1 respectively, and pass the fixing member 4 through the third through hole 31 and the fourth through hole 13 in turn to splice the two platform bodies 1; then insert one end of the support rod group into the sleeve 241, and fix it with the first fixing pin 243, insert the other end of the support rod group into the second mounting hole 111, adjust the height of the support rod group relative to the platform body 1 according to the on-site working conditions, and insert the first connecting member 22 into the pin hole 211 at the corresponding height, and use fasteners to fix the first connecting member 22 relative to the platform body 1, thereby completing the installation of the support assembly 2; finally, insert the guardrail 6 into the base 112 of the platform body 1, and use the third fixing pin 62 to fix it to complete the installation of the guardrail 6, thereby completing the installation of the work platform.
