[0002] With the rapid development of the nuclear power industry, the construction technology of nuclear island buildings has been continuously improving. Among them, the construction of the concrete inner shell of the nuclear island building is a key link in the entire nuclear power plant construction, requiring the use of specialized construction machines. The installation and positioning of the construction machine directly affects the construction quality and efficiency; therefore, the connection method between the construction machine and the concrete inner shell of the nuclear island building is of paramount importance.

[0003] Currently, during the construction of the concrete inner shell of the nuclear island plant, the construction machine is typically fixedly connected to the concrete inner shell using embedded parts or welding. While this connection method ensures the stability of the construction machine, because it is a fixed connection, it often requires re-welding or reinstallation when the position of the construction machine needs to be adjusted, which is cumbersome and time-consuming. Furthermore, the vertical adjustment of the construction machine usually relies on manual operation, resulting in low accuracy and efficiency.

[0004] However, when constructing the concrete inner shell of a nuclear island building, the existing technology directly embeds supports into the concrete inner shell, which limits the overall strength of the concrete inner shell and also affects construction costs. Utility Model Content

[0005] The main purpose of this utility model is to propose a construction machine anchoring fixture and a layered construction machine, which aims to solve the technical problem that in the construction of the concrete inner shell of the nuclear island plant, directly embedding and installing supports on the concrete inner shell will result in limited overall strength of the concrete inner shell and also affect the construction cost.

A sliding mechanism abuts against the side of the base opposite to the concrete inner shell of the nuclear island building. The sliding mechanism can engage with and slide along an external guide member. The external guide member has multiple vertically spaced slots. The sliding mechanism has a mounting groove on the side away from the base. A locking element is rotatably mounted in the mounting groove, and the locking element extends out of the mounting groove in a direction away from the base, and the locking element can be inserted into the corresponding mounting groove and engaged in the groove.

The side of the two second connecting plates away from the base forms the through groove with the inner wall of the two first connecting plates. Each of the two second connecting plates has a second hinge hole concentrically arranged with the first hinge hole. The locking member is installed in the mounting groove and rotates with both the first hinge hole and the second hinge hole simultaneously through a first pin.

[0009] In one embodiment, the connecting assembly further includes a third connecting plate located below the two second connecting plates, the third connecting plate being housed within the vertical channel, and the third connecting plate being connected to the two first connecting plates at both ends along the first direction.

[0010] In one embodiment, the first connecting plate includes a plate body and a connecting lug. The connecting lug is installed on the side of the plate body opposite to the vertical channel. The connecting lug extends along the first direction and has a second bolt hole formed on it, which is concentric with the first bolt hole.

[0011] In one embodiment, the two first connecting plates are further provided with a first insertion hole that extends through the first direction; The sliding component includes: A first limiting plate, which passes through the first insertion hole and through the through slot along the first direction; and... Two second limiting plates are housed within the through groove, and one second limiting plate is mounted on each of the two first connecting plates. A sliding gap is formed between the second limiting plate and the first limiting plate, and the external guide can slide along the sliding gap.

[0024] In existing technologies, during the construction of the concrete inner shell of a nuclear island plant, the construction machine is typically fixed to the concrete structure via pre-embedding or welding. This fixed connection method makes it difficult to adjust the position of the construction machine, requiring re-welding or reinstallation, which consumes a lot of time and manpower. Vertical position adjustment relies on manual operation, which suffers from low precision and poor efficiency. In construction scenarios that require frequent adjustments to the height of the construction machine, traditional fixing methods severely affect the construction progress, and manual adjustment makes it difficult to ensure precise alignment between the construction machine and the concrete inner shell.

[0025] The applicant's research found that directly embedding supports into the concrete inner shell during the construction of the nuclear island plant would limit the overall strength of the concrete inner shell and also affect construction costs.

[0026] This utility model proposes a construction machine anchoring fixture and a layered construction machine.

[0027] Please see Figures 1 to 4 For ease of understanding, this construction machine anchoring fixture 10 is detachably connected to the already manufactured concrete inner shell of the nuclear island plant. The construction machine anchoring fixture 10 includes a base 100, a sliding mechanism 200, and a locking element 400. The base 100 abuts against the outer wall of the concrete inner shell of the nuclear island building. At least two first bolt holes 110 spaced apart along a first direction are formed on the base 100 to allow the construction machine anchoring fixture 10 to be installed on the outer wall of the concrete inner shell of the nuclear island building. The sliding mechanism 200 abuts against the side of the base 100 away from the concrete inner shell of the nuclear island building, and the sliding mechanism 200 can engage with the outer wall of the nuclear island building. The guide member 300 is engaged and can slide along the outer guide member 300. The outer guide member 300 has a plurality of slots 310 distributed vertically at intervals. The sliding mechanism 200 has an installation slot 210 on the side away from the base 100. The locking member 400 is rotatably installed in the installation slot 210, and the locking member 400 can extend out of the installation slot 210 in a direction away from the base 100. The locking member 400 can be inserted into the corresponding installation slot 210 and engaged in the slot 310.

[0028] Specifically, the base 100 refers to the supporting component that bears the main structure. It can be formed by welding steel plates, and the spacing of its first bolt holes 110 can be adjusted according to the size of the concrete structure to achieve quick assembly and disassembly with the inner concrete shell. The sliding mechanism 200 refers to the moving component that realizes height adjustment. It can be a connector with a through groove 230 that cooperates with the guide component. The through groove 230 is slightly larger than the cross-section of the guide component to ensure smooth sliding. The locking component 400 refers to the positioning and locking device. It can be a metal pin with a rotating shaft. Through rotation, it engages or disengages with the locking groove 310 to ensure accurate positioning of the construction machine.

[0029] After the base 100 is bolted to the inner concrete shell, the sliding mechanism 200 moves vertically along the external guide 300. When the construction machine reaches the target height, the locking member 400 rotates outward and inserts into the corresponding slot 310, forming a rigid constraint. At this time, three points of contact are established between the sliding mechanism 200 and the guide: the engagement point between the locking member 400 and the slot 310, and the two contact points between the sliding component 240 and the guide, which together restrict horizontal displacement. When height adjustment is required, the locking member 400 is rotated in the opposite direction to disengage it from the slot 310, allowing the sliding mechanism 200 to continue moving.

[0030] This invention enables rapid assembly and disassembly of the construction machine and the concrete inner shell, avoiding the impact of welding operations on structural integrity. The guide slot 310 utilizes graded positioning to eliminate the error risk associated with manual adjustment. The combined use of the sliding mechanism 200 and the locking element 400 shortens the height adjustment operation time of the construction machine, reducing the time required for a single adjustment compared to traditional methods. This fixture can be reused in different construction stages, reducing equipment investment costs.

[0031] In this embodiment, by setting a base 100, a sliding mechanism 200, and a locking component 400, the base 100 can abut against the outer wall of the concrete inner shell of the nuclear island plant during use, allowing the construction machine anchoring fixture 10 to be installed on the outer wall of the concrete inner shell of the nuclear island plant. The sliding mechanism 200 and the locking component 400 can then lock onto the external guide component 300, thus providing the construction machine with a movable channel for lifting and lowering. Furthermore, since the entire construction machine anchoring fixture 10 is detachably connected to the concrete inner shell of the nuclear island plant, the anchoring fixture can be removed after construction is completed, which not only reduces construction costs but also ensures the overall strength of the concrete inner shell of the nuclear island plant.

[0032] In one embodiment, the sliding mechanism 200 includes a connecting component 220 and a sliding component 240. The connecting component 220 is detachably connected to the base 100. An mounting groove 210 is formed on the connecting component 220. A through groove 230 is formed on the side of the connecting component 220 away from the base 100. An external guide 300 passes through the through groove 230 vertically. The sliding component 240 is installed on the inner wall of the through groove 230 and can move along the external guide 300.

[0033] Specifically, the connecting component 220 is detachably fixed to the base 100, and its through slot 230 allows the external guide 300 to pass vertically through, providing a movement path for the sliding component 240. The sliding component 240 is installed on the inner wall of the through slot 230 and forms a sliding engagement with the external guide 300, allowing the entire sliding mechanism 200 to adjust its height along the external guide 300. When the position of the construction machine needs to be adjusted, the sliding component 240 moves along the external guide 300 to the target height, and then locks itself by engaging with the locking slot 310 through the locking component 400. This structure, through the engagement of the through slot 230 and the sliding component 240, ensures stable guidance during movement and prevents deviation.

[0034] In this embodiment, the combination of the detachable connecting component 220 and the sliding component 240 enables the construction machine to quickly slide and position itself along the external guide 300 without repeatedly disassembling and assembling the fixing components, significantly reducing adjustment time. Simultaneously, the cooperation between the through groove 230 and the sliding component 240 avoids errors from manual adjustment, improving positioning accuracy.

[0035] This design enables stable sliding of the construction machine along the external guide 300, resolving the adjustment difficulties caused by fixed connections. Through the synergistic action of the detachable connecting component 220 and the sliding component 240, construction personnel can quickly adjust the height of the construction machine, reducing downtime and improving construction efficiency. Furthermore, the through-slot 230 structure effectively restricts the lateral displacement of the external guide 300, ensuring a smooth and reliable sliding process and reducing the need for manual intervention.

[0036] In one embodiment, the connecting assembly 220 includes two first connecting plates 221 and two second connecting plates 224. The two first connecting plates 221 are distributed along a first direction and form a vertical channel 222 between them. The two first connecting plates 221 have first hinge holes 223 concentrically arranged along the first direction. The two second connecting plates 224 are spaced apart along the first direction and are both housed within the vertical channel 222. The two second connecting plates 224 are both connected to the base 100. The side of the two second connecting plates 224 away from the base 100 forms a through groove 230 between it and the inner wall of the two first connecting plates 221. The two second connecting plates 224 each have second hinge holes 225 concentrically arranged with the first hinge holes 223. The locking member 400 is installed in the mounting groove 210 and the locking member 400 rotates and engages with both the first hinge holes 223 and the second hinge holes 225 simultaneously through a first pin.

[0037] Specifically, two first connecting plates 221 are arranged at intervals along a first direction to form a vertical channel 222, and two second connecting plates 224 are installed in the channel and fixed to the base 100. A through groove 230 is formed between the upper end of the second connecting plate 224 and the inner wall of the first connecting plate 221, and the external guide 300 can move vertically along the through groove 230. The first hinge hole 223 and the second hinge hole 225 on the first connecting plate 221 and the second connecting plate 224 are concentrically aligned, and the locking member 400 is rotatably installed by passing through the two sets of hinge holes with a first pin. When it is necessary to lock the position of the construction machine, the locking member 400 rotates around the pin and inserts into the slot 310 of the external guide 300, and the hinge structure ensures the stable operation of the locking member 400.

[0038] In this embodiment, the detachable hinged design of the first connecting plate 221 and the second connecting plate 224 allows the locking component 400 to be quickly rotated and unlocked, enabling position adjustment without damaging the structure. Simultaneously, the concentric hinge hole and the engagement with the pin reduce rotational resistance and improve adjustment efficiency.

[0039] In one embodiment, the connecting assembly 220 further includes a third connecting plate 226 located below the two second connecting plates 224. The third connecting plate 226 is housed within the vertical channel 222, and the two ends of the third connecting plate 226 are respectively connected to the two first connecting plates 221 along the first direction.

[0040] Specifically, the third connecting plate 226 is installed below the two second connecting plates 224, and its two ends are welded and fixed to the inner sidewalls of the two first connecting plates 221 respectively. The lateral extension direction of the third connecting plate 226 is consistent with the first direction, so that it can cover the gap between the two second connecting plates 224, thereby forming a continuous support surface. During the installation process, the third connecting plate 226 is pre-processed into a rectangular plate structure, and after adjusting its relative position with the first connecting plates 221 using positioning jigs, the connection is completed by arc welding.

[0041] In this embodiment, by setting a third connecting plate 226, the connecting assembly 220 forms a double-layer support structure, which disperses the contact stress from the sliding mechanism 200 and the external guide 300, and avoids the problem of connecting plate cracking caused by stress concentration.

[0042] In one embodiment, the first connecting plate 221 includes a plate body 227 and a connecting ear 228. The connecting ear 228 is installed on the side of the plate body 227 away from the vertical channel 222. The connecting ear 228 extends along a first direction and has a second bolt hole 250 formed on it, which is concentrically arranged with the first bolt hole 110.

[0043] Specifically, when it is necessary to connect the base 100 to the concrete inner shell of the nuclear island plant, the operator can align the second bolt hole 250 of the connecting lug 228 with the first bolt hole 110 of the base 100 and insert bolts to complete the fixation. Since the connecting lug 228 extends along the first direction and the second bolt hole 250 is concentric with the first bolt hole 110, there is no need to repeatedly adjust the alignment angle during installation; only translation in a single direction is required to complete the hole matching. During disassembly, simply loosening the bolts is sufficient to separate the base 100 from the connecting assembly 220, avoiding damage to the concrete inner shell structure.

[0044] In this embodiment, the independently designed connecting ear 228 structure achieves local adjustability while maintaining connection stability. Operators only need to loosen the bolts in the corresponding area to make fine adjustments without the need for overall disassembly and assembly.

[0045] In one embodiment, the two first connecting plates 221 are further provided with first insertion holes 229 that are disposed through the first direction; the sliding assembly 240 includes a first limiting plate 231 and two second limiting plates 232. The first limiting plate 231 passes through the first insertion hole 229 and is disposed through the through groove 230 along the first direction. The two second limiting plates 232 are both received in the through groove 230, and a second limiting plate 232 is respectively installed on the two first connecting plates 221. A sliding gap is formed between the second limiting plate 232 and the first limiting plate 231, and the external guide 300 can slide along the sliding gap.

[0046] Specifically, after the first limiting plate 231 passes laterally through the first insertion hole 229 of the first connecting plate 221, its two ends are rigidly connected to the first connecting plates 221 on both sides. Two second limiting plates 232 are fixed to the inner walls of the first connecting plates 221 on both sides of the through groove 230, maintaining a parallel distance from the first limiting plates 231. When the external guide 300 is inserted into the through groove 230, its two side surfaces contact the second limiting plates 232 and the first limiting plates 231 respectively, forming a three-point sliding constraint. This structure ensures that the guide can only move in a predetermined direction within the sliding gap, preventing lateral displacement. The cooperation between the second limiting plate 232 and the first limiting plate 231 effectively disperses the frictional stress during the sliding process, while the detachable connection facilitates the replacement and maintenance of worn parts.

[0047] In this embodiment, the sliding assembly 240 forms a modular structure through the through-hole 229 and the first limiting plate 231, ensuring both guiding accuracy and ease of disassembly. The sliding gap formed between the second limiting plate 232 and the first limiting plate 231 replaces the integral guide rail, maintaining guiding stability while reducing machining accuracy. Furthermore, the three-point contact design reduces the frictional contact area compared to the traditional double-sided bonding structure, lowering the sliding resistance by approximately 40%.

[0048] In one embodiment, the second limiting plate 232 is V-shaped, and the V-shaped tip of the second limiting plate 232 is disposed toward the first limiting plate 231.

[0049] Specifically, the second limiting plate 232 refers to a guide component disposed within the through groove 230 for contacting the external guide component 300. It can be implemented by bending a steel plate to form a V-shaped structure, with the V-shaped tip forming linear contact with the surface of the external guide component 300. The V-shaped tip facing the first limiting plate 231 means that the V-shaped opening faces away from the first limiting plate 231, so that the guide component is always subject to symmetrical constraint forces from both sides during sliding.

[0050] When the external guide 300 moves along the sliding gap, the V-shaped tip makes two-point contact with the guide surface. This contact method can automatically correct the guide's offset tendency. The first limiting plate 231 and the two V-shaped second limiting plates 232 together form a three-point positioning structure, forming a stable guide path during the sliding of the guide. Due to the symmetrical characteristics of the V-shaped structure, the guide can adaptively adjust itself through the elastic deformation of the two second limiting plates 232 when subjected to lateral force, avoiding jamming.

[0051] In this embodiment, the V-shaped limiting plate significantly reduces the friction area and increases the sliding speed through linear contact.

[0052] In one embodiment, the first connecting plate 221 is further provided with a second socket 233 and a third socket 234 that are distributed vertically at intervals, and the second socket 233, the third socket 234, the first socket 229 and the first hinge hole 223 are distributed at intervals.

[0053] Specifically, by setting the second socket 233 and the third socket 234, the anchoring fixture can be connected to the external connection structure through the set second socket 233 and the third socket 234, thereby improving the safety of the entire construction machine.

[0054] In one embodiment, the base 100 includes a vertical section 120 and a horizontal section 130 extending along a second direction. The vertical section 120 and the horizontal section 130 are integrally formed. A first bolt hole 110 is formed in the vertical section 120. The horizontal section 130 has a clearance groove that opens away from the vertical section 120 at the position corresponding to the mounting groove 210. A handle is also installed on the vertical section 120.

[0055] Specifically, the base 100 is fixed to the outer wall of the concrete inner shell of the nuclear island plant through the first bolt hole 110 of the vertical section 120, and the horizontal section 130 extends to the bottom of the sliding mechanism 200. The opening direction of the clearance groove corresponds to the moving path of the sliding mechanism 200. When the sliding component 240 slides along the external guide 300, the locking component 400 can pass through the clearance groove and enter the locking slots 310 at different heights, thereby realizing the rapid adjustment of the vertical position of the construction machine. The handle is set on the side of the vertical section 120, and the operator can directly apply force to move the base 100 through the handle without the need for additional tools.

[0056] In this embodiment, the sliding component 240 is provided with a clearance groove to avoid structural interference. Furthermore, in the prior art, the base 100 requires lifting equipment for transport, while the handle makes it possible to manually adjust the position of the base 100.

[0057] Based on the same technical concept, in a second aspect, this utility model also proposes a layered construction machine, including the construction machine anchoring fixture 10 as in the first aspect.

[0058] Specifically, the layered construction machine abuts against the outer wall of the concrete inner shell of the nuclear island plant via its base 100, and is detachably connected using the first bolt hole 110 for easy subsequent adjustment or disassembly. The locking engagement between the sliding mechanism 200 and the external guide 300 allows the construction machine to slide along the guide, achieving vertical position adjustment. When the construction machine needs to be fixed, the locking member 400 is rotated to extend out of the mounting groove 210 and inserted into the corresponding groove 310, thereby restricting the movement of the sliding mechanism 200. The clearance groove on the base 100 provides room for the locking member 400 to move, avoiding interference. During construction, the position adjustment of the construction machine is completed by sliding the sliding mechanism 200 along the external guide 300, and the insertion or removal of the locking member 400 allows for quick positioning or unlocking, reducing manual intervention.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
