Description

Technical Field

[0001] This utility model relates to the field of steel bar processing sheds, specifically to an electrically powered foldable steel bar processing shed for box girder prefabrication yards. Background Technology

[0002] During the prefabrication of box girders, steel bars are generally processed into semi-finished products at a steel bar factory and then transported elsewhere for steel bar binding. The construction cost of steel bar factories is high, and workers mostly work outdoors when binding steel bars, which is not good for their health and cannot work on rainy days. Therefore, a foldable steel bar processing shed is needed to assist in the construction.

[0003] To ensure the smooth and efficient folding and unfolding of the rebar processing shed, a guide rail is typically used. The main structure of the rebar processing shed consists of multiple shed units and a roof, with multiple sets of limiting devices installed on the rail. During the unfolding process, each shed unit runs sequentially on the rail and passes each limiting device in turn. Once the entire shed is fully unfolded, each shed unit is fixed in place by the limiting device at its corresponding position.

[0004] However, in existing technology, when multiple sets of canopy units pass through the various limiting devices on the track in sequence, the limiting devices often misjudge, limiting and fixing one set of canopy units, preventing the entire canopy from fully unfolding. If the misjudge does not occur, it is also difficult for workers to determine when the steel processing canopy is fully unfolded, and it is also difficult to know whether each set of canopy units has been limited and fixed.

[0005] Therefore, an electrically operated, foldable steel bar processing shed is needed to solve the above-mentioned technical problems in box girder prefabrication yards. Utility Model Content

[0015] The side of the column is provided with an installation groove.

[0016] Furthermore, as a preferred embodiment, each set of the shed unit is provided with a trigger rod on the trigger column.

[0017] Furthermore, preferably, the lengths of the trigger rods located on different shed units decrease sequentially.

[0018] Furthermore, as a preferred embodiment, each set of control components includes: a fixed base, a slide rail, a slide block, a connecting base, a control rod, a telescopic column, a spring, an abutment end, and a locking end;

[0019] The track has a fixed seat on its inner side wall, a slide rail on its fixed seat, two sets of slide blocks slidably disposed in the slide rail, a connecting seat fixedly connected to the two sets of slide blocks, and a control rod on the connecting seat.

[0020] The telescopic column is fixedly connected to the slide sidewall near the control lever. The end of the telescopic column away from the slide slides through the trigger mechanism sidewall and extends into it. The end of the telescopic column inside the trigger mechanism is fixedly connected to the abutment end and the locking end. The trigger mechanism is mounted on the fixed base.

[0021] The spring is sleeved on the outer wall of the telescopic column, and the spring is connected between the side wall of the slide block and the side wall of the triggering mechanism.

[0022] Furthermore, as a preferred embodiment, the triggering mechanism includes: a housing, a crossbeam, an upper arc end, a lower arc end, a receiver, a wire, a lamp assembly, and a locking device;

[0023] The housing is mounted on the fixed base, and the cross frame is provided inside the housing. A rotating component is rotatably mounted on the cross frame and a torsion spring is installed at the rotating part. The top end of the rotating component is an upper arc end and the bottom end is a lower arc end.

[0024] The receiver is installed at the lower end of the cross frame, and the receiver is connected to the lamp assembly set on the base via the wire.

[0030] Compared with the prior art, this utility model provides an electrically operated foldable steel bar processing shed for box girder prefabrication yards, which has the following beneficial effects:

[0031] Advantage 1: The base of this utility model can be set to a length that can be selected according to the specific conditions of the construction site, and the length of the sliding rail mechanism on it can also be changed accordingly. Therefore, this utility model can provide shelter for construction workers in different positions during rainy days, eliminating the need to build a steel bar processing plant, reducing investment costs and increasing construction efficiency.

[0032] Advantage 2: During the unfolding operation of the rebar processing shed, each shed unit moves sequentially from right to left on the slide rail mechanism, passing through each control component located on the slide rail mechanism. When each shed unit passes through a terminal control component that is not its own, the control component at that position will not misjudge the situation until the rebar processing shed is fully unfolded. At this point, each shed unit will be positioned by its own terminal control component and fixed in place. Therefore, this invention completely avoids the situation where misjudgment occurs during the unfolding process of the rebar processing shed, preventing it from fully unfolding.

[0033] Advantage 3: When the rebar processing shed is fully extended, multiple sets of lights on the base will light up simultaneously. Workers can use this indicator to determine whether the rebar processing shed is fully extended and whether each shed unit has been fixed in place, thus preventing the rebar processing shed from shifting during construction and causing safety accidents.

[0041] Please see Figures 1-6 This utility model provides an electric foldable steel bar processing shed for a box girder prefabrication yard, comprising: a base 1, a shed body unit 2, a roof 3, a folding mechanism 4, and a slide rail mechanism 5;

[0042] The base 1 is provided with the slide rail mechanism 5, and multiple sets of canopy units 2 are slidably arranged on the slide rail mechanism 5. The top of each set of canopy units 2 is connected to the top of the canopy 3, and the middle of each set of canopy units 2 is connected to the folding mechanism 4.

[0043] The slide rail mechanism 5 includes: a track 51 and a control component 52;

[0044] Among them, the bottom ends of multiple sets of the canopy units 2 are slidably connected to the track 51, and multiple sets of the control components 52 are equidistantly arranged on the inner side wall of each track 51.

[0045] In this embodiment, multiple sets of canopy units 2 and the roof 3 constitute the main structure of the foldable steel bar processing shed. Each set of canopy units 2 can move on the slide rail mechanism 5 to realize the folding and unfolding of the steel bar processing shed. It should be noted that the material of the roof 3 can be tarpaulin or other materials, as long as it does not affect the folding and unfolding of the steel bar processing shed.

[0046] The base 1 in this invention can be selected according to the specific conditions of the construction site, and the length of the upper sliding rail mechanism 5 can also be changed accordingly. Therefore, this invention can provide shelter for construction workers in different locations during rainy days, eliminating the need to build a steel bar processing plant, reducing investment costs, and increasing construction efficiency.

[0047] Furthermore, the number of control components 52 located on the same base 1 corresponds to the number of the canopy units 2.

[0048] Furthermore, the track 51 has an upward concave shape.

[0049] Furthermore, each of the shed units 2 includes: a column 21, a mounting groove 22, a trigger column 23, and an arched component 24;

[0050] Each of the shed units 2 includes two columns 21, and the tops of the two columns 21 are connected by the arched member 24.

[0051] The bottom end of the column 21 is a concave U-shaped structure. The bottom end of the column 21 is slidably connected to the track 51. The trigger post 23 is connected in the concave cavity of the concave U-shaped structure at the bottom end of the column 21, and the trigger post 23 extends into the concave cavity of the concave U-shaped structure on the track 51.

[0052] The side of the column 21 is provided with an installation groove 22.

[0053] It should be noted that the driving method for each set of canopy units 2 to move on the slide rail mechanism 5 can be the existing common electric drive or other existing common drive methods, as long as it can realize the movement of each set of canopy units 2 on the slide rail mechanism 5.

[0054] For a preferred embodiment, please refer to Figure 1 As shown, when the steel bar processing shed is fully extended, each shed unit 2 will be limited and fixed by the control component 52 at its corresponding position. The control component 52 here is called the terminal control component.

[0055] When the rebar processing shed is unfolded, each shed unit 2, from right to left, moves sequentially on the slide rail mechanism 5 (with the leftmost shed unit 2 remaining stationary) and passes sequentially through each control component 52 located on the slide rail mechanism 5. When each shed unit 2 passes through a terminal control component that does not belong to it, the control component 52 at that position will not misjudge (details will be described below) until the rebar processing shed reaches its fully unfolded state. At this point, each shed unit 2 will be positioned by its own terminal control component and fixed in place by it.

[0056] Therefore, this invention can completely avoid misjudgment during the unfolding of the steel bar processing shed, which could prevent it from being fully unfolded.

[0057] Furthermore, each set of the shed unit 2 is provided with a trigger rod 231 on the trigger post 23.

[0058] Furthermore, the lengths of the trigger rods 231 located on different shed units 2 decrease sequentially.

[0059] Furthermore, each set of control components 52 includes: a fixed base 521, a slide rail 522, a slide block 523, a connecting base 524, a control rod 525, a telescopic column 526, a spring 527, an abutment end 528, and a locking end 529;

[0060] The track 51 has a fixed seat 521 on its inner side wall, a slide rail 522 on the fixed seat 521, two sets of slide blocks 523 slidably arranged in the slide rail 522, a connecting seat 524 fixedly connected to the two sets of slide blocks 523, and a control rod 525 on the connecting seat 524.

[0061] The telescopic column 526 is fixedly connected to the side wall of the slide 523 near the control lever 525. The end of the telescopic column 526 away from the slide 523 slides through the side wall of the trigger mechanism 6 and extends into it. The end of the telescopic column 526 located inside the trigger mechanism 6 is fixedly connected to the abutment end 528 and the locking end 529. The trigger mechanism 6 is disposed on the fixed base 521.

[0062] The spring 527 is sleeved on the outer wall of the telescopic column 526, and the spring 527 is connected between the side wall of the slide block 523 and the side wall of the triggering mechanism 6.

[0063] Furthermore, the triggering mechanism 6 includes: a housing 61, a crossbeam 62, an upper arc end 63, a lower arc end 64, a receiver 65, a wire 66, a lamp assembly 67, and a locking device 68;

[0064] The housing 61 is disposed on the fixed base 521, and the cross frame 62 is disposed inside the housing 61. A rotating component is rotatably disposed on the cross frame 62 and a torsion spring is installed at the rotating part. The top end of the rotating component is an upper arc end 63 and the bottom end is a lower arc end 64.

[0065] The receiver 65 is installed at the lower end of the cross frame 62, and the receiver 65 is connected to the lamp group 67 disposed on the base 1 through the wire (66);

[0066] The locking device 68 is provided on the inner side wall of the housing 61.

[0067] For a preferred embodiment, please refer to Figure 4 and Figure 5 As shown, taking the example of one of the canopy units 2 moving to the position of its own terminal control component: when the canopy unit 2 moves close to the control component 52, the trigger rod 231 on the trigger column 23 at the bottom of the column 21 will drive the control rod 525 to move synchronously. The control rod 525 will drive the telescopic column 526 to slide into the housing 61 and compress the spring 527 with the help of the slide block 523.

[0068] The contact end 528 on the telescopic column 526 contacts the upper arc end 63 on the rotating component, causing the rotating component to start rotating. The lower arc end 64 on the rotating component will then contact the receiver 65 and energize it. With the help of the wire 66, the lamp group 67 will start to light up. When the contact end 528 on the telescopic column 526 contacts the rotating component, the locking end 529 on the telescopic column 526 will simultaneously contact the locking device 68 and lock it in place. At this point, the canopy unit 2 is in its final position and is limited and fixed by the terminal control component.

[0069] It should be noted that the energizing method between the lower arc end 64 and the receiver 65 can be a common electromagnetic energizing method. The locking and fixing method between the locking device 68 and the locking end 529 can be a common opposite magnetic pole attraction method, and a controller can be set to control the presence or absence of its magnetism. Therefore, to release the limiting fixation of the shed unit 2, it is only necessary to control the disappearance of the magnetic attraction between the locking device 68 and the locking end 529, and the limiting fixation will be released under the action of the spring 527 and the torsion spring. At the same time, the lamp group 67 will start to turn off, and the steel bar processing shed can be fully deployed.

[0070] It should be noted that an auxiliary spring can be added between the rotating part and the crossbar 62 to replace the torsion spring and release the limit fixation.

[0071] Furthermore, the length of the control lever 525 on each group of control components 52 increases sequentially.

[0072] For a preferred embodiment, please refer to Figure 6As shown, taking three sets of canopy units 2 as an example: the length of the trigger rod 231 decreases sequentially, i.e., A>B>C, and the length of the control rod 525 increases sequentially, i.e., a<b<c. That is to say, when the three sets of canopy units 2, E, F, and G, move on the slide rail mechanism 5, the G set of canopy units 2 will first pass through the e and f set of control components 52, and then reach its own terminal control component (i.e., the f set of control components 52).

[0073] Due to the decreasing and increasing lengths of the trigger rod 231 and control rod 525 of this utility model, the limit fixing operation will not be triggered when the G group shed unit 2 passes through the e and f group control components 52, because the length of the trigger rod 231 on the G group shed unit 2 is C, and it will not come into contact with the control rod 525 with lengths of a and b. The same applies to the movement of the E and F group shed units 2.

[0074] Therefore, this invention can completely avoid the situation where the control component 52 misjudges and causes the steel bar processing shed to jam during the unfolding process, preventing it from fully unfolding.

[0075] In a preferred embodiment, since the number of canopy units 2 and control components 52 located on the same base 1 corresponds, when canopy units 2 of group G are fixed in a limiting position, canopy units 2 of groups E and F are simultaneously fixed in a limiting position. That is, multiple sets of lights 67 located on the base 1 will light up simultaneously. Workers can use this indicator to determine whether the rebar processing canopy is fully deployed and whether each canopy unit 2 has been fixed in a limiting position, thus preventing the rebar processing canopy from shifting during construction and causing safety accidents.

[0076] Furthermore, the folding mechanism 4 includes: a first diagonal bar group 41, a second diagonal bar group 42, and a connecting rod 43;

[0077] The first diagonal bar group 41 is rotatably connected to the mounting groove 22, and the second diagonal bar group 42 is rotatably connected to the mounting groove 22, and is rotatably connected to the first diagonal bar group 41 to form a cross structure. This is a set of cross folding components.

[0078] The cross-folding components are configured in two groups, and each group of cross-folding components is connected to each other by the connecting rod 43.

[0079] In this embodiment, please refer to Figure 2 As shown, the folding mechanism 4 is a common cross-folding component, which helps the steel bar processing shed to achieve stable unfolding and folding.

[0080] It should be noted that, depending on specific needs, side panels can be added between the uprights 21 of each group of shed units 2 (such as...). Figure 1As shown at point D in the middle, the side fabric should be made of a material that does not affect the folding and unfolding of the steel bar processing shed.

[0081] In practice, multiple sets of canopy units 2 and the roof 3 constitute the main structure of the foldable steel bar processing shed. Each set of canopy units 2 can move on the slide rail mechanism 5 to realize the folding and unfolding of the steel bar processing shed. This can completely avoid the situation where the control component 52 misjudges and causes the steel bar processing shed to jam during the unfolding process, resulting in it not being able to fully unfold. After the steel bar processing shed is fully unfolded, multiple sets of lights 67 located on the base 1 will light up at the same time. The staff can use this indicator standard to judge whether the steel bar processing shed has been fully unfolded, and can also determine whether each set of canopy units 2 has been limited and fixed.

[0082] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
