Description

Technical Field

[0001] The present invention relates to the field of prefabricated building equipment, and particularly to a box girder frame bar separation mechanism, a box girder skeleton forming device and a skeleton forming method. Background Art

[0002] A box girder is a type of beam in bridge engineering. It can be divided into prestressed reinforced concrete box girders and steel box girders according to materials. Among them, the prestressed reinforced concrete box girder is constructed on-site. First, a skeleton is built using steel bars, and then it is formed by pouring concrete.

[0003] In the existing production process of reinforced concrete box girders, first, a jig of corresponding specifications needs to be made according to the length of the box girder. Then, workers manually install the frame bars one by one on the jig at a set spacing. After the frame bars are fixed on the jig, workers manually insert the horizontal steel bars into the frame bars and tie them up. Finally, concrete is poured. In this process, only fixing the frame bars requires hundreds or even thousands of manual repetitive operations to install the frame bars one by one on the jig, which is time-consuming and laborious, and the efficiency is very low. Especially in the process of inserting the horizontal steel bars into the frame bars, since the frame bars and horizontal steel bars are usually threaded steel bars and are relatively heavy, the frictional resistance between the horizontal steel bars and the frame bars is very large, and it requires multiple people to cooperate to complete the insertion, with a large labor intensity and low efficiency. Moreover, in the process of inserting the horizontal steel bars into the frame bars, both the jig and the horizontal steel bars require a large production site. For example, at least 65 meters of site is required to produce the steel bar skeleton of a 30-meter-long box girder, and the requirement for the site area is high. Summary of the Invention

[0025] A box girder skeleton forming device, comprising:

[0026] A machine base;

[0027] A movable working platform slidably fitted on the machine base. The movable working platform has a loading mechanism. The loading mechanism has at least two outrigger rods extending along the sliding direction of the movable working platform for hanging box girder frame bars;

[0028] A number of floating support mechanisms. The fixed ends of the floating support mechanisms are accommodated in the machine base and arranged at intervals along the sliding direction of the movable working platform. The floating ends of the floating support mechanisms extend upward into the accommodation grooves of the machine base. The fixed ends and the floating ends are connected by telescopic members. When the movable working platform slides above the floating end, the floating end floats downward to allow the movable working platform to pass through;

[0029] A horizontal bar splint placed on the machine base and located at the distal end of the sliding path of the movable working platform. The horizontal bar splint is provided with a horizontal bar limiting mechanism for limiting horizontal steel bars;

[0030] And the box girder frame bar positioning and separating mechanism. The box girder frame bar positioning and separating mechanism is installed at the front section of the movable working platform and corresponds to the loading mechanism and the horizontal bar splint.

[0032] The support blocks are located at both ends in the sliding direction of the movable working platform, and each extends a support arm for supporting the frame bar.

[0033] The telescopic member includes a fifth linear motion mechanism and a second guiding assembly. The fifth linear motion mechanism is connected to the middle section of the bottom of the transverse support member, and the second guiding assembly is connected to the bottom of the support block.

[0034] The mobile working platform is provided with guide wheels and a first gear. The machine base is provided with a first guide rail for cooperating with the guide wheels and a first rack for cooperating with the first gear. The first gear is in transmission connection with a corresponding power device.

[0035] The mobile working platform is provided with a second guide rail and a second rack in the same direction as its sliding direction; the bottom of the box girder frame bar separating mechanism is provided with a slider and a second gear, and the second gear is in transmission connection with a corresponding power device.

[0036] A method for forming a framework includes using the box girder framework forming device as described above. The method includes the following steps:

[0037] a. Arrange the horizontal bars. Place other horizontal bars on the machine base along the extending direction of the machine base. Support the horizontal bars at the bottom of the box girder framework through a plurality of floating support mechanisms, fix the ends of the horizontal bars to the flat bar clamping plates, and sleeved a plurality of frame bars on the outrigger.

[0038] b. The mobile working platform moves towards the horizontal bar clamping plate.

[0043] g. The clamping part extends out for material blocking, and the separating plate returns to its original position.

[0044] h. Repeat steps d - g to complete the forming operation of the framework section.

[0045] The beneficial effects of adopting the present invention are as follows.

[0046] A box beam frame reinforcement separation mechanism, a fixed plate and a movable plate assembly that can move relative to the fixed plate in the thickness direction of the fixed plate, the clamping rod of the movable plate assembly can block a number of frame reinforcements arranged in the thickness direction of the fixed plate, the separation plate of the fixed plate can separate the frame reinforcements against the movable plate assembly from the intercepted frame reinforcements, and then the movable plate assembly can grab the frame reinforcement separated by the fixed plate, and then through the relative movement between the movable plate assembly and the fixed plate, the distance between the movable plate assembly and the fixed plate can be changed, and then the frame reinforcement grabbed by the movable plate assembly can be further separated from the remaining frame reinforcements and positioned to a specified position. The fixed plate is provided with at least one pair of separation plates that can be extended and retracted into the first accommodating space, and the two separation plates are respectively arranged on both sides of the first accommodating space. After the separation plate is extended, it will enter the gap between the first frame reinforcement that has passed through the first accommodating space and the second frame reinforcement that remains in the first accommodating space, so as to separate the first frame reinforcement from the subsequent frame reinforcements. When the separation plate is retracted, the subsequent frame reinforcement can continue to enter the first accommodating space under the push;

[0047] The movable plate assembly is provided with a second accommodating space which can accommodate the frame reinforcement and allow it to pass through. The separated frame reinforcement will be grabbed and then passed through by the movement of the movable plate assembly, and then positioned at the designated position of the horizontal steel bar. The movable plate assembly is provided with at least one pair of clamping rods which can be extended and retracted into the second accommodating space. Before pushing the frame reinforcement, the clamping rod will extend a portion into the second accommodating space. After pushing the frame reinforcement, the frame reinforcement will be blocked by the clamping rod, and the frame reinforcement to be separated will abut against the clamping rod. After the frame reinforcement is separated from the subsequent frame reinforcement by the separation plate, the clamping rod will be further extended to grab the frame reinforcement. Two clamping rods are respectively arranged on both sides of the second accommodating space, so that both sides of the frame reinforcement are blocked. At the same time, when the clamping rod is further extended, pressure is applied to the frame reinforcement on both sides at the same time to achieve the grasping of the frame reinforcement; the end of the clamping rod is provided with a clamping part for realizing the blocking and grasping of the frame reinforcement, and the outer end of the clamping part has a first protrusion for blocking the material, and the first protrusion and the separation plate are staggered in the thickness direction of the fixed plate. When the movable plate assembly moves toward the fixed plate to the proximal position, the first protrusion and the separation plate have a gap for accommodating the steel bar in the thickness direction of the fixed plate, the separation plate will be located behind the separated frame reinforcement, and the first protrusion will be located in front of the separated frame reinforcement, so that the separated frame reinforcement is restricted in front and behind and kept vertical, which is convenient for the subsequent grasping of the separated frame reinforcement; when the movable plate assembly moves away from the fixed plate to the distal position, the separation plate and the clamping rod are staggered in the thickness direction of the fixed plate, and the distance between the two adjacent frame reinforcements can be enlarged.

[0048] The extended end of the clamping part has a clamping groove, which can limit the captured frame reinforcement to prevent the frame reinforcement from moving or falling off during subsequent movement and positioning. The two side walls of the clamping groove respectively form a first protrusion and a second protrusion. The first protrusion and the second protrusion are arranged in the thickness direction of the fixed plate. The extended length of the first protrusion is greater than the extended length of the second protrusion, so that the clamping groove can accommodate the side steel bars of the frame reinforcement. The extended length of the first protrusion is greater than the extended length of the second protrusion. When intercepting and grabbing the frame reinforcement, the clamping rod partly extends into the first accommodating space first, so that the part of the first protrusion longer than the second protrusion enters the first accommodating space to complete the blocking of the frame reinforcement. At this time, the second protrusion has not yet entered the second accommodating space. After the frame reinforcement is separated, the clamping rod is further extended, so that the second protrusion also extends into the first accommodating space, and then the side steel bars of the frame reinforcement enter the clamping groove and abut against the bottom of the clamping groove to complete the grabbing of the frame reinforcement.

[0049] The thickness of the second protrusion in the thickness direction of the fixed plate is less than or equal to the thickness of the separation plate. The second protrusion also needs to be inserted into the gap between the separated frame rib and the subsequent frame rib. Before the second protrusion is inserted into the gap, the separation plate has entered the gap. Therefore, the thickness of the second protrusion in the thickness direction of the fixed plate is less than or equal to the thickness of the separation plate, which can prevent the second protrusion from getting stuck or being unable to enter the gap between the separated frame rib and the subsequent frame rib. When the movable plate assembly moves toward the fixed plate to the proximal position, the projection of the second protrusion in the vertical direction is located on the separation plate. In order to ensure accurate positioning and ensure that the separated frame rib can enter the clamping groove, the end face of the second protrusion facing the separated frame rib and the end face of the separation plate facing the separated frame rib should be on the same vertical plane.

[0050] A box beam skeleton forming device, comprising:

[0051] The machine base is used to install other components and support the steel frame of the box girder;

[0052] A mobile working platform slidably matched on the machine base, the mobile working platform having a loading mechanism, the loading mechanism having at least two outriggers extending along the sliding direction of the mobile working platform, used for mounting the box girder frame reinforcement, by the movement of the mobile working platform on the machine base, the relative position between the frame reinforcement and the horizontal reinforcement is changed, so that the frame reinforcement is positioned to a specified position on the horizontal reinforcement, and then the frame reinforcement is automatically inserted into the horizontal reinforcement, completing the automatic construction of the box girder reinforcement skeleton;

[0053] A number of floating support mechanisms, the fixed ends of the floating support mechanisms are accommodated in the machine base and arranged at intervals along the sliding direction of the moving working platform. The floating ends of the floating support mechanisms extend upward into the accommodation grooves of the machine base. The fixed ends and the floating ends are connected by telescopic members. When the moving working platform slides above the floating end, the floating end floats downward to allow the moving working platform to pass through. Since the floating support mechanism can yield to the moving working platform in time, it prevents the movement of the moving working platform on the machine base from being interfered. At the same time, during the movement of the moving working platform, only the floating support mechanisms located below the moving working platform yield, and the floating support mechanisms in other positions continue to support the horizontal steel bars, preventing the horizontal steel bars from deforming due to lack of support;

[0054] Horizontal steel bar clamping plates are placed on the machine base and at the far end of the sliding path of the moving working platform. The horizontal steel bar clamping plates are provided with horizontal steel bar limiting mechanisms for limiting the horizontal steel bars, preventing the horizontal steel bars from moving, so that the horizontal steel bars can be aligned with the frame steel bars, facilitating the frame steel bars to be sleeved on the horizontal steel bars;

[0055] And the box girder frame steel bar positioning and separating mechanism described in any one of the above. The box girder frame steel bar positioning and separating mechanism is installed at the front section of the moving working platform and corresponds to the loading mechanism and the horizontal steel bar clamping plates. The moving direction of the movable plate assembly of the box girder frame steel bar positioning and separating mechanism is parallel to the sliding direction of the moving working platform, and it can separate and grab a single frame steel bar from the loaded frame steel bars.

[0056] When arranging steel bars and forming the skeleton, first fix the horizontal steel bars on the horizontal steel bar clamping plates. The horizontal steel bars are supported by the horizontal steel bar clamping plates and the floating support mechanisms. Then load the frame steel bars on the extension rods of the loading mechanism. Next, start the moving working platform. As the moving working platform moves, change the positions of the frame steel bars and the horizontal steel bars, and sleeve the frame steel bars on the horizontal steel bars. When the moving working platform moves, the floating support mechanisms also yield, while maintaining the support of the horizontal steel bars and not affecting the movement of the moving working platform. Then use the box girder frame steel bar positioning and separating mechanism to grab and separate the frame steel bars, and accurately position the separated frame steel bars to the designated positions of the horizontal steel bars, realizing the automatic construction of the box girder steel bar skeleton. When the moving working platform moves away from the horizontal steel bar clamping plates, the bundled skeleton segments are supported by a number of floating support mechanisms.

[0057] The present invention adopts a construction method different from that of the existing box girder steel bar skeletons. After fixing the horizontal steel bars first, the frame steel bars are then sleeved onto the horizontal steel bars, avoiding the heavy labor of multiple people collaborating to insert the horizontal steel bars into hundreds of frame steel bars. At the same time, the required construction site is smaller; the box girder frame steel bar positioning and separating mechanism is used to automatically sleeve the frame steel bars onto the horizontal steel bars and can automatically position the frame steel bars to the designated positions on the horizontal steel bars, avoiding the complicated and inefficient labor of manually fixing hundreds of frame steel bars. While ensuring the accuracy of steel bar placement, the work efficiency is improved.

[0058] The floating end includes: a transverse support member, with upward support blocks provided at both ends of the transverse support member;

[0059] a roller shaft, the roller shaft is horizontally placed above the transverse support member, and both ends of the roller shaft are rotatably supported on the corresponding support blocks; several rollers are spaced and supported on the roller shaft, and the outer periphery of the rollers has a groove around the circumference of the roller for restricting the horizontal steel bars, further preventing them from being misaligned. At the same time, through the rotatable roller shaft with rollers, the process of inserting the horizontal steel bars is more labor-saving.

[0060] The telescopic member includes a fifth linear motion mechanism and a second guiding component. The fifth linear motion mechanism is connected to the middle section of the bottom of the transverse support member, and the second guiding component is connected to the bottom of the support block. By arranging the fifth linear motion mechanism and the second guiding component at the bottom of the support member, it is prevented that the horizontal steel bars at the top of the support member are interfered. By using two guiding rods, the floating support mechanism will have a better supporting effect and can prevent the support member from twisting. By arranging the fifth linear motion mechanism between the two guiding rods, the transmitted thrust is more uniform, and it can prevent the second guiding component from getting stuck during the movement process.

Detailed implementation manners

[0080] Referring to the attached drawings, the specific implementation manners of the present invention will be described in detail.

[0081] See Figures 1 to 17 The present invention provides an embodiment of a box girder frame bar separation mechanism 100. A box girder frame bar separation mechanism 100 includes a fixed plate 110 and a movable plate assembly 120 that can move in the thickness direction of the fixed plate 110 relative to the fixed plate 110.

[0082] The fixed plate 110 is provided with at least a pair of separation plates 112 that can extend and retract into the first accommodation space 111. The two separation plates 112 are respectively arranged on both sides of the first accommodation space 111. After the separation plates 112 extend out, they will enter the gap between the first frame bar that has passed through the first accommodation space 111 and the second frame bar remaining in the first accommodation space 111, so as to realize the isolation and separation of the first frame bar and the subsequent frame bars. When the separation plates 112 retract, the subsequent frame bars can continue to enter the first accommodation space 111 under the push.

[0083] The movable plate assembly 120 is provided with a second accommodation space 121 for accommodating and allowing the frame bars to pass through. The movable plate assembly 120 is provided with at least a pair of clamping rods 123 that can extend and retract into the second accommodation space 121. The clamping rods 123 are arranged offset in the height direction from the separation plate 112. The end of the clamping rod 123 is provided with a clamping portion 1231 for grasping the frame bars. The outer extension end of the clamping portion 1231 has a first protrusion portion 1232 for material blocking to block the frame bars. The first protrusion portion 1232 is arranged offset from the separation plate 112 in the thickness direction of the fixed plate 110. The offset gap is for accommodating individual frame bars. The separated frame bars will be further grasped by the clamping portion 1231 of the clamping rod 123 in the second accommodation space 121.

[0084] In the embodiment, the two clamping rods 123 are respectively arranged on both sides of the second accommodation space 121, so that both sides of the frame bars are blocked. When material blocking is required, the clamping rods 123 extend out a part, and material blocking can be achieved through the first protrusion portion 1232. At the same time, when the clamping rods 123 extend further, pressure and clamping are applied to the frame bars on both sides simultaneously to grasp the frame bars.

[0085] When the movable plate assembly 120 moves towards the fixed plate 110 to the proximal position, the first protrusion portion 1232 and the separation plate 112 have a gap in the thickness direction of the fixed plate 110 for accommodating steel bars, for isolating or separating individual frame bars. The separation plate 112 will be behind the separated frame bars, and the first protrusion portion 1232 will be in front of the separated frame bars, so that the separated frame bars are restricted and kept vertical in both the front and back, facilitating subsequent grasping of the separated frame bars.

[0086] When the movable plate assembly 120 moves away from the fixed plate 110 to the distal position, the separation plate 112 and the clamping rods 123 are arranged offset in the thickness direction of the fixed plate 110, and the relative movement away realizes continuous bar arrangement along the direction of the fixed plate 110.

[0087] Further, the outer extension end of the clamping portion 1231 has a clamping groove 1234, which can limit the frame bars captured, preventing the frame bars from loosening or falling off during subsequent movement and positioning. Both side walls of the clamping groove 1234 respectively form a first protrusion 1232 and a second protrusion 1233. The first protrusion 1232 and the second protrusion 1233 are arranged in the thickness direction of the fixing plate 110. The length of the outer extension of the first protrusion 1232 is greater than the length of the outer extension of the second protrusion 1233, so that the clamping groove 1234 can accommodate the side steel bars of the frame bar. When intercepting and grasping the frame bar, first, the clamping rod 123 partially extends into the first accommodating space 111, so that the part of the first protrusion 1232 longer than the second protrusion 1233 enters the first accommodating space 111 to complete the blocking of the frame bar. At this time, the second protrusion 1233 has not yet entered the second accommodating space 121. After the frame bar is separated, the clamping rod 123 further extends, so that the second protrusion 1233 also extends into the first accommodating space 111, and then the side steel bars of the frame bar enter the clamping groove 1234 and abut against the bottom of the clamping groove 1234 to complete the grasping of the frame bar.

[0088] Further, when the movable plate assembly 120 moves towards the fixed plate 110 to the proximal position, the vertical projection of the front side of the separation plate 112 is located within the width region of the vertical projection of the clamping portion. This front end face, i.e., the side face towards the movable plate assembly, can control the gap between the separation plate 112 and the clamping portion 1231, and can prevent the phenomenon that after the frontmost frame rib tilts backward, the clamping portion 1231 cannot grasp the frame rib on its running path. The vertical projection of the tip of the second protrusion 1233 corresponds to the width region of the vertical projection of the separation plate 112, and the lower projection of the separation plate 112 corresponds to the gap. Adopting this structure can ensure the second protrusion and can effectively insert into the gap, avoiding inserting on the frame rib. Adopting this arrangement can achieve automation and can prevent the separation plate 112 or the first protrusion from inserting on the frame rib or failing to grasp the frame rib during continuous operation, and can ensure the continuity of the automated operation. In this embodiment, the second protrusion can be the same width as the separation plate 112 and is arranged correspondingly in the vertical direction. Further still, for facilitating separation and inserting into the gap, the end of the separation plate 112 is a first wedge-shaped column 1121, and the end of the second protrusion 1233 is a second wedge-shaped column 1235. The two inclined surfaces of the wedge-shaped column are arranged in the thickness direction of the fixed plate 110 and converge at the top of the wedge-shaped column. Setting the end of the separation plate 112 and the end of the second protrusion 1233 as wedge-shaped columns can make the separation plate 112 and the second protrusion 1233 easily extend into the gap between the frame rib to be separated and the subsequent frame rib. At the same time, the wedge-shaped column of the second protrusion 1233 also facilitates guiding the separated frame rib into the clamping groove 1234. The thickness of the second protrusion 1233 in the thickness direction of the fixed plate 110 is less than or equal to the thickness of the separation plate 112. The second protrusion 1233 also needs to insert into the gap between the separated frame rib and the subsequent frame rib. Before the second protrusion 1233 inserts into this gap, the separation plate 112 has already entered this gap. Therefore, making the thickness of the second protrusion 1233 in the thickness direction of the fixed plate 110 less than or equal to the thickness of the separation plate 112 can prevent the second protrusion 1233 from getting stuck or failing to enter when entering the gap between the separated frame rib and the subsequent frame rib. When the movable plate assembly 120 moves towards the fixed plate 110 to the proximal position, the vertical projection of the second protrusion 1233 in the vertical direction is located on the separation plate 112. To ensure accurate positioning and ensure that the separated frame rib can enter the clamping groove 1234, the end face of the second protrusion 1233 facing the separated frame rib and the end face of the separation plate 112 facing the separated frame rib should be in the same vertical plane.

[0089] Specifically in this embodiment, the fixed plate 110 is provided with two pairs of separation plates 112, and the four separation plates 112 are trapezoidally distributed. The fixed plate 110 and the movable plate assembly 120 can be made of materials with strong anti-deformation ability such as stainless steel and fiberglass. The tails of the two separation plates 112 on the same side are connected by a first connecting rod 114. A first linear motion mechanism 113 for controlling the reciprocating linear motion of the first connecting rod 114 is arranged on the fixed plate 110, which can make the moving distances of the ends of the four separation plates 112 when extending into and retracting from the gap between the frame ribs the same. After connecting the separation plates 112 on the same side and then connecting the first linear motion mechanism 113, the separation plates 112 on the same side can be simultaneously extended and retracted;

[0090] The movable plate assembly 120 may include two symmetrically arranged movable plates 122. A clamping rod 123 is arranged on each movable plate 122, and the four clamping rods 123 are trapezoidally distributed. The tails of the two clamping rods 123 on the same side are connected by a second connecting rod 126. A second linear motion mechanism 124 and a third linear motion mechanism 125 for controlling the reciprocating linear motion of the second connecting rod 126 are arranged on each movable plate 122, which can make the moving distances of the ends of the four clamping rods 123 when extending into and retracting from the gap between the frame ribs the same. After connecting the clamping rods 123 on the same side and then connecting the second linear motion mechanism 124 and the third linear motion mechanism 125, the separation plates 112 on the same side can be simultaneously extended and retracted, and the purpose of first extending a part to intercept the frame ribs and then continuing to extend to grab the frame ribs can be achieved.

[0091] A first guiding component 131 is arranged between the fixed plate 110 and the movable plate assembly 120. The guiding component can be a structure of a guide sleeve and a guide post in cooperation, or a structure of a guide post and a mating hole in cooperation. The fixed plate 110 and the movable plate assembly 120 are connected by a fourth linear motion mechanism 130, which can realize the relative motion between the fixed plate 110 and the movable plate assembly 120, and then realize further positioning the grabbed frame ribs to a specified position for tying the frame ribs and horizontal steel bars.

[0092] In order to reduce the displacement distance of the clamping rod 123, make the upper and lower end faces of the clamping rod 123 enter or exit the gap of the frame ribs simultaneously, and prevent rubbing against the frame ribs, see Figures 4 - 6 , the end of the clamping rod 123 is inclined, and the inclination angle is the same as the inclination angle of the side steel bars of the frame ribs; similarly, the inclination angle of the clamping groove 1234 is the same as the inclination angle of the side steel bars of the frame ribs, which is more fitting to the side of the frame ribs when grabbing the frame ribs, and the grabbing of the frame ribs is more stable.

[0093] See Figures 14 - 17, in order to improve the automation and intelligence of the equipment, in an embodiment of a box girder frame bar separation mechanism 100, an induction block 160 for installing a sensor is provided in the thickness direction of the separation plate 112 of the first convex portion 1232. The induction block 160 may be integrally structured with the first convex portion 1232. The separation plate 112 is provided with a relief groove 170 for accommodating the induction block 160. Through the sensor, it is possible to automatically determine whether the frame bars are aligned and whether the frame bars are placed in the accurate position.

[0094] In the above embodiment, each linear motion mechanism is a cylinder, a hydraulic cylinder or an electric telescopic cylinder; of course, it may also be a rack drive structure for linear reciprocating motion, or a slider 140 drive mechanism for linear reciprocating motion; of course, in this embodiment, based on the simplified structure and usage cost, it is preferably to use a cylinder as the linear motion mechanism, that is, the first linear motion mechanism 113, the second linear motion mechanism 124, the third linear motion mechanism 125, and the fourth linear motion mechanism 130 adopt cylinders.

[0095] The fixing plate 110 may be integrally or separately provided, such as Figures 1 to 3 , in some embodiments of a box girder frame bar separation mechanism 100, the fixing plate 110 is integrally provided. The two sides of the fixing plate 110 are connected by a bottom cross plate. Adopting an integral structure, the relative position accuracy on the fixing plate 110 is high, and the number of components can be reduced. Such as Figures 14 - 16 , in some other embodiments of a box girder frame bar separation mechanism 100, the fixing plate 110 is separately provided. The fixing plate 110 includes two symmetrically arranged base plates 115. A separation plate 112 that can extend and retract into the first accommodation space 111 is respectively provided on each base plate 115. A first accommodation space 111 is formed by the gap between the two base plates 115. The split structure can reduce the size of the fixing plate 110 and can also be adaptively adjusted according to the width of the frame bars, making its application range wider. The box girder frame bar separation mechanism 100 can move along a set path. And in order to prevent the fixing plate 110 from tilting, a reinforcing rib is added on one side of the fixing plate 110.

[0096] During operation, the fixed plate 110 is provided with a first accommodation space 111 that can accommodate and allow the frame bars to pass through. A number of frame bars arranged in the thickness direction of the fixed plate 110 will be pushed towards the movable plate assembly 120. When the first frame bar passes through the first accommodation space 111, it will be blocked by the first protrusion 1232 on the clamping rod 123 of the movable plate assembly 120; that is, a part of the clamping rod 123 of the box girder frame bar separation mechanism 100 extends to intercept the frame bars. The separation plate 112 extends to separate the frame bar at the forefront from the subsequent frame bars. The clamping rod 123 further extends, uses the clamping groove 1234 to grab the frame bar, and then by adjusting the distance between the movable plate assembly 120 and the fixed plate 110 or moving the box girder frame bar separation mechanism 100 itself along the guide rail, the separated frame bar is positioned at the designated position, and the distance between the first frame bar and the subsequent frame bars is widened. The frame bar clamped by the clamping part 1231 is taken, tied, or welded. When the frame bar is removed, the clamping rod 123 retracts, and at the same time, the movable assembly moves towards the fixed plate 110 assembly. The first protrusion on the clamping part 1231 extends out for material blocking, and the separation plate 112 retracts to complete one operation.

[0097] A cycle is realized, and then automatic positioning, grasping, separating the frame bar at the forefront, and accurately positioning the separated frame bar to the designated position are achieved, which is convenient for taking, tying, or welding. This embodiment can be used alone to separately extract grouped steel bars or can be paired with other automated equipment to achieve automated continuous operation.

[0098] The present invention also provides an embodiment of a box girder skeleton forming device. Refer to Figures 1 to 17 , the box girder skeleton forming device includes a machine base 200, a movable working platform 300, a number of floating support mechanisms 210, a horizontal bar clamping plate 400, and the box girder frame bar positioning and separation mechanism of the above embodiment.

[0099] The machine base 200 is used to install the remaining components and support the box girder steel bar skeleton, and can be formed by building several I-beams into a rectangular steel truss structure.

[0100] The mobile working platform 300 is slidably matched with the machine base 200. The mobile working platform 300 has a loading mechanism 310. The loading mechanism 310 has at least two outriggers 311 extending along the sliding direction of the mobile working platform 300, which are used to mount the box girder frame reinforcement. By moving the mobile working platform 300 on the machine base 200, the relative position between the frame reinforcement and the horizontal reinforcement is changed, so that the frame reinforcement group is positioned to the specified position on the horizontal reinforcement, and then the frame reinforcement is automatically inserted into the horizontal reinforcement to complete the automatic construction of the box girder reinforcement skeleton. In this embodiment, the mobile working platform 300 is provided with a guide wheel 320 and a first gear 330. The machine base 200 is provided with a first guide rail 220 matched with the guide wheel 320 and a first rack 230 matched with the first gear 330. The first gear is connected to the corresponding power equipment in a transmission manner. The guide wheel 320 and the first guide rail 220 can make the mobile working platform 300 slide easily, and the first gear 330 and the first rack 230 cooperate to push the mobile working platform 300 to slide relative to the base, and the sliding distance can be accurately controlled. Of course, the base 200 and the mobile working platform 300 can also adopt other existing sliding support structures, and a driving mechanism can also be set between the mobile working platform 300 to make the base 200 and the mobile working platform 300 move relative to each other.

[0101] A plurality of floating support mechanisms 210, wherein the fixed ends 211 of the floating support mechanisms 210 are accommodated in the machine base 200 and are arranged at intervals along the sliding direction of the mobile working platform 300, and the floating ends 212 of the floating support mechanisms 210 extend upward into the receiving groove of the machine base 200, and the fixed ends 211 and the floating ends 212 are connected by telescopic members 213. When the mobile working platform 300 slides above the floating ends 212, the floating ends 212 float downward to allow the mobile working platform 300 to pass through. At the same time, the floating support mechanism 210 at the bottom of the mobile working platform 300 gives way to prevent the movement of the mobile working platform 300 on the machine base 200 from being interfered. At the same time, during the movement of the mobile working platform 300, only the floating support mechanism 210 located below the mobile working platform 300 gives way, and the floating support mechanisms 210 at other positions continue to support the horizontal steel bars to prevent the horizontal steel bars from being deformed due to lack of support. The floating end 212 below the frame reinforcement sinks, so that the horizontal reinforcement at this location is suspended, avoiding the frame reinforcement from scratching the horizontal reinforcement. The floating support mechanism 210 can be controlled to float down and up by a travel switch.

[0102] Further, the floating end 212 includes: a transverse support member 2121, with upward support blocks 2122 provided at both ends of the transverse support member 2121; a roller shaft 2123, which is horizontally disposed above the transverse support member 2121, and both ends of the roller shaft 2123 are rotatably supported on the corresponding support blocks 2122; a plurality of rollers 2124, which are spaced apart and supported on the roller shaft 2123. The outer circumference of the roller 2124 has a groove around the circumference of the roller 2124 for restricting the horizontal steel bars, further preventing them from being misaligned. At the same time, through the rotatable roller shaft 2123 with the rollers 2124, the process of inserting the horizontal steel bars is more labor-saving. The support blocks 2122 are located at both ends of the sliding direction of the mobile working platform 300, and each extends a support arm 2125 for supporting the frame bars, which can prevent the frame bars and horizontal steel bars from lacking support and deforming. In particular, it supports the already tied box girder skeleton section and disperses the pressure.

[0103] The horizontal bar clamp 400 is placed on the machine base 200 and is located at the far end of the sliding path of the mobile working platform 300. The horizontal bar clamp 400 is provided with a horizontal bar limiting mechanism 410 for limiting the horizontal steel bars. The horizontal bar limiting mechanism 410 can be a device such as a sleeve or a bracket for limiting and fixing the end of the horizontal steel bar to prevent the starting end of the horizontal steel bar welding from moving, so that the horizontal steel bar can be aligned with the frame bar, facilitating the frame bar to be sleeved into the horizontal steel bar.

[0104] The box beam frame reinforcement positioning and separation mechanism is installed at the front section of the mobile working platform 300 and corresponds to the loading mechanism 310 and the horizontal reinforcement clamping plate 400. The moving direction of the movable plate assembly 120 of the box beam frame reinforcement positioning and separation mechanism is parallel to the sliding direction of the mobile working platform 300, and can separate and grab a single frame reinforcement from the loaded frame reinforcement. The mobile working platform 300 is provided with a second guide rail 340 and a second rack 350 in the same sliding direction as itself; the bottom of the box beam frame reinforcement separation mechanism 100 is provided with a slider 140 and a second gear 150, wherein the slider 140 and the second guide rail 340 form a relative sliding support, and the second rack 350 cooperates with the second gear 150 to enable the second gear 150 of the box beam frame reinforcement separation mechanism 100 to be transmission-connected with the corresponding power equipment. , through the cooperation of the slider 140 and the second guide rail 340, the cooperation of the second rack 350 and the second gear 150, the distance that the box beam frame reinforcement separation mechanism 100 moves along the mobile working platform 300 can be accurately controlled, so that the box beam frame reinforcement separation mechanism 100 removes the frame reinforcement from the frame reinforcement to be separated, and continues to separate the frame reinforcement; it is particularly suitable for the frame reinforcement to move relative to the extension rod after a part of the frame reinforcement is used, and the frame reinforcement at a farther distance is removed. In some other embodiments, if the box beam frame reinforcement separation mechanism 100 and the mobile working platform 300 do not produce relative slippage, in order to facilitate the pushing of the frame reinforcement at a farther distance on the extension rod to the box beam frame reinforcement separation mechanism 100 for supply operation, the mobile working platform 300 also includes a pushing device 360, which is used to push the frame reinforcement to be separated on the extension rod 311, so as to continue to separate the frame reinforcement. In the embodiment of the present invention, the pushing device 360 is a pushing plate; of course, if the pushing device 360 is not provided, the frame reinforcement can also be manually pushed to the specified position.

[0105] The telescopic member 213 includes a fifth linear motion mechanism 2131 and a second guiding assembly 2132. The fifth linear motion mechanism 2131 is connected to the middle section of the bottom of the transverse support member 2121, and the second guiding assembly 2132 is connected to the bottom of the support block 2122. By arranging the fifth linear motion mechanism 2131 and the second guiding assembly 2132 at the bottom of the support member, it is possible to prevent the horizontal steel bars at the top of the support member from being interfered. By using two guiding rods, the floating support mechanism 210 will have a better supporting effect and can also prevent the support member from twisting. By arranging the fifth linear motion mechanism 2131 between the two guiding rods, the transmitted thrust will be more uniform, and it can prevent the second guiding assembly 2132 from getting stuck during movement. In an embodiment of the box girder skeleton forming device, the fifth linear motion mechanism 2131 used is a cylinder. Of course, in the above embodiment, each linear motion mechanism can be a cylinder, a hydraulic cylinder or an electric telescopic cylinder; it can also be a rack drive structure for linear reciprocating motion, or a slider 140 drive mechanism for linear reciprocating motion; of course, based on simplifying the structure and use cost in this implementation, a cylinder is preferably used as the linear motion mechanism.

[0106] The present invention adopts a building method different from that of the existing box girder steel skeletons. After fixing the horizontal steel bars first, then the frame bars are sleeved onto the horizontal steel bars, which avoids the heavy labor of multiple people collaborating to insert the horizontal steel bars into hundreds of frame bars. At the same time, the required construction site is also smaller; the box girder frame bar positioning and separating mechanism is used to automatically sleeve the frame bars onto the horizontal steel bars and can automatically position the frame bars to the designated positions on the horizontal steel bars, avoiding the complicated and inefficient labor of manually fixing hundreds of frame bars. While ensuring the accuracy of steel bar arrangement, the work efficiency is improved.

[0107] When using the above box girder skeleton forming device to form the box girder steel bar skeleton, first cut horizontal steel bars and bent frame bars of appropriate lengths according to the specifications of the box girder to be formed. Arrange the horizontal bars at the bottom of the box girder skeleton on the machine base and support them through a number of floating support mechanisms 210. Then insert and fix one end of the horizontal steel bar into the horizontal bar clamping plate 400. This step can either use a transport vehicle to place the horizontal steel bar parallel to the machine base 200, then lift the horizontal steel bar and insert it into the horizontal bar limiting mechanism 410, or place the horizontal steel bar on the rollers 2124 on the roller shafts 2123, then push the horizontal steel bar in front of the horizontal bar clamping plate 400, and then lift the horizontal steel bar and insert it into the horizontal bar limiting mechanism 410. Since the frame bars at the bottom of the box girder skeleton need to bear the entire skeleton, and at the same time this horizontal bar is at the bottom of the equipment and is not convenient for flexible arrangement, the horizontal bars at the bottom of the box girder skeleton need to be arranged in place before the box girder skeleton is formed. For other horizontal bars, such as those connected to the side or top of the frame bars, they can be flexibly arranged. It is convenient for personnel to stand beside the machine base to arrange them, or they can be arranged manually. Just fix the end of the horizontal bar at a higher position of the frame bar to the horizontal bar clamping plate 400 first, and the rest of the extended part can freely extend and hang vertically. Just ensure that the starting position of welding is stable. During the welding process, the single bar at a higher position can be adjusted in real time to fit the frame bar. After connecting to the frame bar, after the frame at a higher position is tied or welded, some of the frame bars forming part of the box girder skeleton are positioned. When using the box girder skeleton forming device, first lay the bottom horizontal bars forming the frame skeleton, and then thread other horizontal bars, or other horizontal bars can also be arranged outside the frame bars. The vertical sections of the tails of other horizontal bars can maintain a high degree of flexibility in arrangement. After several frame bars are sleeved on the extension rod, move the working platform 300 towards the horizontal bar clamping plate 400. During the entire movement process, when moving above the corresponding floating support mechanism 210, the floating end 212 moves downward to allow the frame bar to pass through. When stopping when the working platform 300 is close to the horizontal bar clamping plate 400 and then moving back in the reverse direction, first the clamping part 1231 of the movable plate assembly 120 blocks the outermost frame bar, then the separating plate 112 is inserted, and then the clamping part 1231 is further inserted and clamps the outermost frame bar. At the same time, the movable plate assembly 120 and the fixed plate 110 assembly move away from each other, and at the same time the moving platform moves back to tie or weld the frame bar clamped by the clamping part 1231. After the welding of this frame bar is completed, the clamping rod 123 retracts, and at the same time the movable assembly moves towards the fixed plate 110 assembly. The first protrusion on the clamping part 1231 extends out for material blocking, and the separating plate 112 returns to its original position to complete one operation. Continuing to operate in this cycle, the frame bars are arranged at intervals in sequence. Of course, during the process of the moving platform moving back, when the unbundled frame on the moving platform moves above the corresponding floating end 212, the floating end 212 sinks to allow the unbundled frame to pass through smoothly.

[0108] See Figures 1 to 17 , the present invention also provides a method for forming a framework: using the box girder framework forming device described above, the method arrangement includes:

[0109] a. Arrange the horizontal bars, place other horizontal bars on the machine base along the extending direction of the machine base, support the horizontal bars at the bottom of the box girder framework through a plurality of floating support mechanisms 210, fix the ends of the horizontal bars to the flat bar clamping plates, and sleave a plurality of frame bars on the outrigger 311;

[0110] b. Move the working platform 300 towards the horizontal bar clamping plate 400. During the whole movement process, when moving above the corresponding floating support mechanism 210, the floating end 212 moves downward to allow the frame bar to pass through. When the working platform 300 is close to the far end of the sliding path, stop and correspond to the horizontal bar clamping plate 400;

[0111] c. The clamping part 1231 of the movable plate assembly 120 blocks the outermost frame bar,

[0112] d. Then the separating plate 112 is inserted into the gap on the back side of the outermost frame bar, and then the clamping part 1231 is further inserted and clamps the outermost frame bar;

[0113] e. The movable plate assembly 120 and the fixed plate 110 assembly move away from each other, the moving platform retracts. When the moving platform moves above the corresponding floating support mechanism 210, the floating end 212 moves downward to allow the frame bar to pass through, and bind or weld the frame bar clamped by the clamping part 1231 with the horizontal bar,

[0114] f. When the binding or welding of the clamped frame bar is completed, the clamping rod 123 retracts, and the movable assembly moves towards the fixed plate 110 assembly,

[0115] g. The clamping part extends out for material blocking, and the separating plate 112 returns to its original position,

[0116] h. Repeat steps d - g to complete the forming operation of the framework section.

[0117] Compared with the process of using a tooling rack to fix the frame bars and then manually inserting the horizontal steel bars one by one during the traditional box girder forming process, the insertion process using the present invention is more labor - saving, has lower requirements for the site size, and has a higher degree of automation; after fixing the horizontal steel bars, start the moving working platform 300 loaded with frame bars, first sleave the loaded frame bars onto the horizontal steel bars. During the sleaving process, the floating support mechanism 210 actively makes way for the moving working platform 300 and the frame bars on this platform in advance, which not only does not affect the sliding of the moving working platform 300, but also can maintain the maximum support for the horizontal steel bars to prevent the horizontal steel bars from deforming due to lack of support.

[0118] By adopting the present invention, a large number of repetitive manual operations in the traditional process of forming the box girder steel bar framework can be avoided. The box girder frame bar separation mechanism 100 is used to grasp, separate and position the frame bars to the designated positions of the horizontal steel bars, realizing automatic and intelligent steel bar arrangement, greatly improving the efficiency and accuracy of forming the box girder steel bar framework. At the same time, the floor area occupied during construction is smaller, and the requirements for the construction site are lower.

[0119] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
