DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figures 1 to 10 As shown, the present invention provides an assembled work platform specially used for the construction of large structures such as ships, including mold columns 1. Two sets of mold columns 1 are provided. The mold columns 1 can be lifted and lowered longitudinally. The two sets of mold columns 1 are respectively fixedly arranged on both sides of a foundation pit 2, and two sets of working beams 16 are arranged in parallel on the tops of the two sets of mold columns 1. The extension direction of the two sets of working beams 16 is the same as that of the foundation pit 2 and are arranged on both sides of the foundation pit 2.

[0047] A plurality of bottom beams 3 are provided, and the bottom beams 3 are movably arranged on the top opening of the foundation pit 2 . A detachable module bottom plate 7 is provided on the plurality of bottom beams 3 to form a pressure-bearing platform 4 on the top of the foundation pit 2 .

[0048] A top beam 6, wherein a plurality of top beams 6 are provided, wherein the plurality of top beams 6 are movably arranged between two sets of working beams 16 and located directly above the pressure-bearing platform 4, and a detachable module bottom plate 7 is provided on the plurality of top beams 6 to form a working platform 8, and an accommodating gap is provided between the working platform 8 and the end side of the working beam 16 close to the foundation pit 2, and a groove position for placing the structure to be constructed is formed between the accommodating gap and the pressure-bearing platform 4.

[0049] The bottom beam 3 and the top beam can slide synchronously in a direction away from the foundation pit 2 to form a foundation groove for accommodating a ship between the foundation pit 2 and the working cross beam 16 .

[0050] This device is mainly used to set up a construction work platform on the side of the foundation pit 2 for the construction of large structures such as ships. Specifically, a pressure-bearing platform 4 for carrying structures is formed by setting a bottom beam 3 and a module bottom plate 7 above the foundation pit 2, and a work platform 8 is further set on the pressure-bearing platform 4 to construct the structures set on the pressure-bearing platform 4. In addition, after the module bottom plate 7 on the pressure-bearing platform 4 and the work platform 8 is taken down, the top opening of the foundation pit 2 is opened and the top beam 6 is retracted by moving the top beam 6 and the bottom beam 3, thereby forming a foundation slot that can accommodate ships. At this time, workers can construct ships on the work beams 16 on both sides of the foundation slot. The length of the work beam 16 and the work platform 8 in this device can be set shorter to mainly construct the bow position.

[0051] Further, such as Figure 1 As shown, a step ladder 15 leading to the work platform 8 is provided on the side of the work beam 16 .

[0052] like Figure 2 As shown, an extension platform 17 is arranged on the opposite side surfaces of the two sets of working beams 16, and a working position 18 is arranged on the extension platform 17. The end side of the top beam 6 is movably arranged on the working position 18, and the working positions 18 on both sides and the working platform 8 together form an operating platform.

[0053] By forming an operating platform by the working position 18 and the working platform 8 together, the operator's working range can be expanded, and construction can be carried out from three sides of the object to be constructed simultaneously, rather than being limited to a single side or double side position.

[0054] In this device, the movement of the top beam 6 can be divided into two modes: overall movement and individual movement, which are suitable for different application scenarios.

[0055] Among them, as an embodiment, a spacing area is provided on one side of the epitaxial platform 17 close to the working beam 16, and a gap compensation block 19 and a locking long strip block 20 are sequentially placed in the spacing area in the direction extending from the working beam 16 to the position of the foundation pit 2. The length direction of the spacing area, the gap compensation block 19 and the locking long strip block 20 is the same as the length direction of the working beam 16.

[0056] Among them, a plurality of engaging holes 21 are equidistantly provided on the engaging long strip block 20 for connecting with the end of the top beam 6, and the gap compensation block 19 is used to fill the gap between the engaging long strip block 20 and the working beam 16, and the width of the gap compensation block 19 is greater than the depth of the top beam 6 inserted into the engaging long strip block 20.

[0057] After the work platform 8 is assembled and turned, when the device is used to construct a part of the structure, in order to enable the whole work platform 8 to be framed around the side of the object to be constructed in a sleeved manner for synchronous construction, the top beam 6 is detachably connected through the engaging strip block 20. After the gap compensation block 19 is pulled out from the spacing area, the engaging strip block 20 is moved toward the working cross beam 16, so that the top beam 6 is separated from the engaging strip block 20, and the top beam 6 can be installed by self-adjusting and mobilizing, and the object to be constructed can be framed.

[0058] In addition, another advantage of this method is that the construction location of the building to be constructed may be irregular in shape and outward-expanding, such as the cabin location in the middle of the hull, the circular tower top location on the top of the steel structure, and workers may need to move backwards adaptively during continuous construction. Therefore, by moving the top beam 6 near the location to be constructed backwards a slightly smaller distance and then laying a module bottom plate 7 of corresponding width (a plurality of grooves with different spacings can be set on the bottom surface of the module bottom plate 7, and different grooves are selected to be mounted on the top beam 6 to match different widths), there is no need to move the entire top beam 6 at the rear, so it can be completed by manual operation, achieving the purpose of reducing the frequency of starting the power source and reducing energy consumption. This method is a way of manually operating a top beam 6 to adapt to smaller displacement situations, thereby improving the flexibility and accuracy of the device.

[0059] like Figure 3 As shown, further, the length of the top beam 6 is smaller than the distance between the inner bottom surfaces of the two engaging holes 21 on both sides of its end. When the ends of the top beam are plugged into the engaging holes 21, there is a gap between the two end surfaces of the top beam and the inner bottom surfaces of the engaging holes 21.

[0060] A prying notch is provided on the side where the gap compensation block 19 abuts against the engaging long strip block 20, and the prying notch includes an oblique notch 22 located at the upper position of the gap compensation block 19, and the oblique notch 22 is arranged toward the engaging long strip block 20, and the top of the oblique notch 22 is an outward expansion opening, and the bottom is a contraction opening. When the lower position of the gap compensation block 19 abuts against the engaging long strip block 20, there is a gap between the contraction opening of the oblique notch 22 and the engaging long strip block 20, and an inward buckle notch 23 is provided in the middle position of the gap compensation block 19, below the contraction opening of the oblique notch 22, and the inward buckle notch 23 is recessed toward the gap compensation block 19.

[0061] During the specific operation, since the squeezing of the engaging strip block 20 may make it more difficult to pull out the gap compensation block 19, the device is provided with a prying notch. During the specific operation, the worker inserts the crowbar into the prying notch, first moves the engaging strip block 20 to the side away from the gap compensation block 19 in the oblique notch 22, so that there is a certain gap between it and the gap compensation block 19, and then pries it in the opposite direction, using the end of the crowbar to deeply insert into the inner buckle notch 23, and pry the gap compensation block 19 with the engaging strip block 20 as the pad fulcrum, so that it is easier to tilt the gap compensation block 19, so as to move the engaging strip block 20 and disengage it from the top beam 6. When the previous top beam 6 moves to fit the adjacent top beam 6, it can be removed and taken out, and then the operation is repeated.

[0062] In addition, the device provides another implementation method, specifically connecting multiple top beams to form an integral structure for movement, specifically:

[0063] like Figure 4 As shown, a spacing area is provided on one side of the epitaxial platform 17 close to the working beam 16, and a locking long strip block 20 is provided in the spacing area. One side of the locking long strip block 20 is abutted against the working beam 16, and the other side is locked and connected with the end of the top beam 6. The locking long strip block 20 is slidably set in the spacing area along the length direction of the working beam 16.

[0064] Multiple top beams 6 are connected in series through a connecting kit 37 to form a top beam overall structure 24, and the top beam overall structure 24 is connected to an external driving structure. The external driving structure drives the top beam overall structure 24 and the engaging long strip block 20 to slide linearly on the epitaxial platform 17 synchronously to expand or reduce the area of ​​the groove position.

[0065] like Figure 5 As shown, in this embodiment, a plurality of top beams 6 are connected by a connection kit 37 to form a top beam overall structure 24, so that it can be moved as a whole. On the one hand, it can adapt to the requirements of continuous construction of the structure to the rear, and on the other hand, the working platform 8 can be quickly folded up to form a base slot to accommodate ships.

[0066] The connection kit 37 is a mature structure in the prior art, which can be provided with a circle ring on the chain structure, and the circle ring is set outside the top beam 6 and fixedly connected to the top beam 6, so as to ensure that the distance between the top beams 6 does not change while connecting the top beams 6. The chain structure is used between adjacent circle rings, which makes the subsequent storage process more convenient.

[0067] In addition, the connection kit 37 can be bent as a chain structure, and the chain structure is formed by rotating and splicing a plurality of component units similar to a chain.

[0068] The advantage of forming a top beam overall structure 24 with multiple top beams 6 through a connection kit 37 is that all top beams 6 can be moved as a whole. By moving the top beam overall structure 24 as a whole, not only is the standardization better and the requirements for the module base plate 7 are low, but the operation is also easy and simple.

[0069] like Figure 1 and Figure 6 As shown, further, a storage device 25 for retracting the top beam 6 is provided between the two working beams 16, and the storage device 25 includes a transverse plate 29 fixedly connected to the end of the extension platform 17 and a longitudinal plate 30 connected to the transverse plate 29 and extending downward, an arc-shaped bending profile is provided at the connection position between the transverse plate 29 and the longitudinal plate 30, a lintel gap 31 is provided between the bottom of the longitudinal plate 30 and the foundation pit 2, an installation area 32 is provided on the longitudinal plate, an opening is provided at the lower end of the installation area 32, and a retracting assembly 28 is provided in the installation area 32.

[0070] The winding assembly 28 includes a roller 33 rotatably installed in the installation area 32, a chain plate 34 is rotatably arranged on the roller 33, a clamping sleeve 35 for receiving the top beam 6 is arranged on the outer wall of the chain plate 34, the clamping sleeve 35 is located below the extension platform 17, a one-way limiter 36 is arranged on the clamping sleeve 35, the one-way limiter 36 opens toward the inner side of the clamping sleeve 35 under the pressure of the self-weight of the top beam 6 to allow the top beam 6 to enter the clamping sleeve 35, and the one-way limiter 36 opens toward the outer side of the clamping sleeve 35 under the pressure of the traction force greater than the weight of the top beam 6 to allow the top beam 6 to escape from the clamping sleeve 35.

[0071] Both the engaging long strip block 20 and the connecting kit 37 are chain-type structures that can be bent along the bending contour of the connecting position of the horizontal plate 29 and the vertical plate 30, and a limiting top plate 38 is arranged on the spacing area. The limiting top plate 38 is arranged directly above the engaging long strip block 20. The limiting top plate 38 is used to limit the upward convex bending of the engaging long strip block 20 when sliding on the extension platform 17.

[0072] When the top beam 6 on the top beam overall structure 24 moves linearly to the rear end of the epitaxial platform 17 , it falls into the clamping sleeve 35 in sequence and is received by the winding assembly 28 .

[0073] By setting up the storage device 25, the top beam overall structure 24 can be directly stored under the operating platform, and when the bending sections of the horizontal plate 29 and the longitudinal plate 30 are at the same height as the top of the vertical through hole 40, the top beam overall structure 24 can be fully laid on the extension platform 17 at one time by applying reverse force, making the storage and laying of the overall device more convenient.

[0074] Specifically, since the engaging strip block 20 and the connecting kit 37 are both chain-type structures that can bend along the bending contours of the transverse plate 29 and the longitudinal plate 30, when external force drives the top beam overall structure 24 and the engaging strip block 20 to move toward the mold column 1, the engaging strip block 20 and the connecting kit 37 will bend downward due to the gravity of the top beam 6 when passing through the bending section of the bending contour. When the top beam 6 falls downward after passing the tail end of the transverse plate 29, it will fall onto the clamping sleeve 35 of the reeling assembly 28 directly below, and be received by the reeling assembly 28. As the top beam overall structure 24 continues to move, the reeling assembly 28 synchronously rotates in a loop, causing the clamping sleeve 35 to move downward and replace it with a new clamping sleeve 35, so that the top beam 6 can fall into the clamping sleeve 35 alone, and the engaging strip block 20 and the connecting kit 37 are separated on both sides of the reeling assembly 28 to form a storage state. Among them, the gap between adjacent clamping sleeves 35 on the chain plate 34 can be smaller than the gap between adjacent top beams 6 to set as many clamping sleeves 35 as possible, and the different gaps are compensated by the rotation rate to ensure that the top beam 6 can fall into the clamping sleeve synchronously.

[0075] The rotation of the reel assembly 28 can be driven by a separate driving source. Furthermore, a beam gap 31 is provided below the reel assembly 28, and a one-way stopper 36 is provided on the clamping sleeve 35. This allows the reel assembly 28 to pass through the beam gap 31 (and due to the one-way stopper 36, the top beam 6 will not fall out of the clamping sleeve 35 due to the top beam 6) when driving the top beam 6 to pass through the curved section below it, and reach the other side of the reel assembly 28 for storage. Thereby, the storage capacity of the reel assembly 28 is improved.

[0076] Further, such as Figure 7 and Figure 8 As shown, a transverse hole 39 is opened on the inner side of the working beam 16, and the end of the transverse hole 39 close to the storage device 25 is connected to a vertical hole 40. The vertical hole 40 is located on the outer side of the end of the extension platform 17, and the end of the top beam 6 extends into the interior of the working beam 16 through the transverse hole 39 and is connected to the external driving structure arranged in the working beam 16.

[0077] The external driving structure includes two transmission rollers 41 rotatably mounted on the inner wall of the working beam 16, the transmission rollers 41 are meshedly connected with a chain belt 42, the chain belt 42 is provided with a push plate 43, the push plate 43 abuts against the end side of the top beam 6, the chain belt 42 or the transmission rollers 41 are connected to a power source, and the power source drives the push plate 43 to drive the top beam 6 to move through the transverse hole 39 and the vertical hole 40 and fall into the sleeve 35.

[0078] Among them, the power source for driving the driving roller 41 or the chain belt 42 to move can be an electric, hydraulic or other power source in the prior art (not shown in the figure).

[0086] The selective connection between the first annular chain belt 12 and the second sprocket 13 for rotation can be realized by using the spring sheath section in the prior art. By inserting and pulling out the spring sheath section, the first annular chain belt 12 can be disconnected, thereby disconnecting from the second sprocket 13 (the first annular chain belt 12 is preferably disconnected from the second sprocket 13), so as to facilitate the rise and fall of the overall structure. When the overall device needs to construct a ship, the mold column is raised to the specified position, and then the spring sheath section is inserted to connect the first annular chain belt 12 with the second sprocket 13, and then the power input of the power source (the power source can be a rotating motor, and the output end of the motor is connected to the transmission roller) drives the top beam 6 and the bottom beam 3 to move synchronously and be stored to form a base slot through the transmission structure.
