Description

Technical Field

[0001] This utility model relates to the field of construction scaffolding technology, specifically a construction scaffolding for bridge construction. Background Technology

[0002] During bridge construction, due to the sheer size of the bridge, it is inevitable that workers will need to climb onto the bridge surface for tasks such as reinforcement and painting. This process requires the use of bridge scaffolding.

[0003] For example, the national authorized patent announcement number CN213653219U discloses a construction scaffold for bridge construction. The technical problem this utility model aims to solve is that some existing bridge construction scaffolds on the market can only move laterally in one direction. To solve this problem, this utility model provides a construction scaffold for bridge construction, including a fixed frame. The inner wall of the fixed frame is provided with a sliding groove, and the two ends of the sliding groove are connected by a main guide rod. In use, after the fixed frame is fixedly installed on the bridge by workers, the main linear motor and the secondary linear motor are controlled to allow the transfer frame to move within the inner circle of the fixed frame's planar cross-section. During this process, the transfer frame, connected to the scaffold via a transfer arm and a hydraulic electric telescopic rod, allows the scaffold to move to any position within the inner circle of the fixed frame's planar cross-section. Furthermore, the height can be adjusted using the hydraulic electric telescopic rod, enabling it to adapt to complex construction environments for bridge construction.

[0004] However, the aforementioned construction scaffolds used for bridge construction cannot adjust the angle of the suspended platform in three axes, making it difficult to keep the suspended platform parallel to or at a suitable angle to these complex structural surfaces. This requires construction workers to constantly adjust their posture or use special tools to adapt, increasing the difficulty of construction and reducing the accuracy and quality of construction. Utility Model Content

[0005] The purpose of this utility model is to provide a construction gantry for bridge construction, so as to solve the problem mentioned in the background art that the gantry cannot be adjusted in three axes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A construction gantry for bridge construction includes: a truck, a connecting plate fixedly installed in the truck bed, a turntable rotatably installed on the upper surface of the connecting plate, a guide frame fixedly installed on the upper surface of the turntable, a guide plate slidably installed in the guide frame, a U-shaped frame fixedly installed in the guide plate, a transmission column rotatably installed on the lower surface of the U-shaped frame, the transmission column being threaded onto the outer surface of a first threaded rod, the first threaded rod being fixedly installed between the turntable and the guide frame, a sliding frame fixedly installed at one end of the guide plate, and a bridge construction auxiliary lifting mechanism slidably installed in the sliding frame.

[0008] Preferably, a first motor is fixedly mounted on the upper surface of the turntable, and a gear is fixedly mounted on one end of the output shaft of the first motor. The gear meshes with a gear ring, and the gear ring is fixedly mounted on the upper surface of the connecting plate and located at the periphery of the turntable.

[0009] Preferably, a second motor is fixedly installed inside the guide plate, and a sprocket is fixedly installed on the outer surface of the output shaft of the second motor. A chain is fitted on the outer surface of the sprocket, and the other end of the chain is fitted on the outer surface of the sprocket on the lower surface of the transmission column, so that the sprocket can push the guide plate to slide vertically within the guide frame by rotating the thread.

[0010] Preferably, the bridge construction auxiliary lifting mechanism includes a guide rail frame, which is slidably installed in a sliding frame. A suspended basket is slidably installed in the guide rail frame, and the suspended basket is fixedly connected to a wire rope. The wire rope is wound on the outer surface of the winding column, which is fixedly installed on the outer surface of the output shaft of the third motor. The third motor is fixedly installed on the upper surface of the support frame, and the support frame is fixedly installed on the upper surface of the guide rail frame.

[0011] Preferably, a second threaded rod is fixedly installed on the lower surface of the guide rail frame, and a sprocket is threadedly installed on the outer surface of the second threaded rod. The sprocket is rotatably installed in two sets of U-shaped frames. The two sets of U-shaped frames are fixedly installed on the upper surface of the mounting plate. The mounting plate is fixedly installed on the lower surface of the sliding frame. A fourth motor is fixedly installed on the upper surface of the mounting plate. A sprocket is fixedly installed at one end of the output shaft of the fourth motor. A chain is fitted on the outer surface of the sprocket of the fourth motor, and the other end of the chain is fitted on the outer surface of the sprocket rotating in the U-shaped frame.

[0012] Preferably, this allows the sprocket to push the second threaded rod through the rotating thread, causing the guide rail frame to slide back and forth within the sliding frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the turntable, guide frame, first threaded rod, gear ring, first motor, gear, second motor, sliding frame and bridge construction auxiliary lifting mechanism, when in use, the second motor can be started to drive the transmission column to perform threaded transmission on the outer surface of the first threaded rod, so that the transmission column can push the guide plate vertically upward in the guide frame through threaded transmission, and then the guide plate can drive the bridge construction auxiliary lifting mechanism slidably installed in the sliding frame to be lifted out of the truck bed until it is higher than the bridge guardrail and then it can stop.

[0015] Then the first motor can be started to drive the gear meshing transmission gear ring to drive the turntable to rotate in the connecting plate, which in turn enables the turntable to drive the bridge construction auxiliary lifting mechanism that is slidably installed in the guide frame to rotate at an angle until the bridge construction auxiliary lifting mechanism is rotated to the required position and then it can be stopped.

[0016] Then, the bridge construction auxiliary lifting mechanism can be activated to extend outward at the rotated angle, that is, outside the bridge. After extending to the required length, it can be lifted and lowered to the outer wall of the bridge for workers to carry out painting and other treatments. Through the three-axis control of vertical, rotation and extension, it can flexibly reach and carry out construction on the superstructure, substructure or complex side shape of the bridge, greatly improving its adaptability to different bridge structures. After use, it can be rotated and lowered back into the truck bed for storage.

[0017] 2. Through the design of the guide frame, suspended platform, third motor, winding column, second threaded rod, and fourth motor, the third motor is activated after vertical and angular rotation. This drives the sprocket inside the U-shaped frame to perform threaded transmission on the outer surface of the second threaded rod, which in turn pushes the second threaded rod to push the guide frame back and forth within the sliding frame to extend its length. Once the guide frame has extended the suspended platform that is slidably installed inside to the outside of the bridge, the third motor is activated to release the wire rope wound on the outer surface of the winding column. After the wire rope is released, the suspended platform is no longer under traction and can slide down the guide frame to the outer wall of the bridge for workers to paint and perform other treatments. While workers are working, a driver can also move a truck to move the suspended platform to different parts of the bridge for workers to carry out construction operations. Combined with the extension and lowering functions of the suspended platform, continuous construction of different parts of the bridge can be achieved without frequent disassembly and reinstallation of the suspended platform, reducing downtime during construction and further improving construction efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-2 As shown, this embodiment provides a construction gantry for bridge construction, including: a truck 1, a connecting plate 101 fixedly installed in the truck bed of the truck 1, a turntable 102 rotatably installed on the upper surface of the connecting plate 101, a guide frame 103 fixedly installed on the upper surface of the turntable 102, a guide plate 104 slidably installed in the guide frame 103, a U-shaped frame 111 fixedly installed in the guide plate 104, a transmission column 112 rotatably installed on the lower surface of the U-shaped frame 111, the transmission column 112 being threaded onto the outer surface of a first threaded rod 105, the first threaded rod 105 being fixedly installed between the turntable 102 and the guide frame 103, a sliding frame 106 fixedly installed at one end of the guide plate 104, and a bridge construction auxiliary lifting mechanism 2 slidably installed in the sliding frame 106.

[0025] The turntable 102 has a first motor 108 fixedly mounted on its upper surface. A gear 109 is fixedly mounted on one end of the output shaft of the first motor 108. The gear 109 meshes with a gear ring 107. The gear ring 107 is fixedly mounted on the upper surface of the connecting plate 101 and located at the periphery of the turntable 102.

[0026] The guide plate 104 is fixedly installed with a second motor 110. The output shaft of the second motor 110 is fixedly installed with a sprocket. A chain is fitted on the outer surface of the sprocket. The other end of the chain is fitted on the outer surface of the sprocket on the lower surface of the transmission column 112, so that the sprocket can push the guide plate 104 to slide vertically in the guide frame 103 by rotating the thread.

[0027] Through the design of turntable 102, guide frame 103, first threaded rod 105, gear ring 107, first motor 108, gear 109, second motor 110, sliding frame 106 and bridge construction auxiliary lifting mechanism 2, in use, the second motor 110 can be started to drive the transmission column 112 to perform threaded transmission on the outer surface of the first threaded rod 105, thereby enabling the transmission column 112 to push the guide plate 104 vertically upward within the guide frame 103 through threaded transmission, thereby enabling the guide plate 104 to drive the bridge construction auxiliary lifting mechanism 2, which is slidably installed within the sliding frame 106, to be lifted out of the truck bed of the truck 1 until it is higher than the guardrail of the bridge and then stops.

[0028] Then, the first motor 108 can be started to drive the gear 109 to mesh with the transmission gear ring 107 to drive the turntable 102 to rotate within the connecting plate 101. This allows the turntable 102 to drive the bridge construction auxiliary lifting mechanism 2, which is slidably installed within the guide frame 103, to rotate at an angle until the bridge construction auxiliary lifting mechanism 2 is rotated to the required position and then stopped.

[0029] Subsequently, the bridge construction auxiliary lifting mechanism 2 can be activated to extend outward at the rotated angle, that is, outside the bridge. After extending to the required length, it can be lifted and lowered to the outer wall of the bridge for workers to perform painting and other treatments. Through the three-axis control of vertical, rotation and extension, it can flexibly reach and carry out construction on the superstructure, substructure or complex side shape of the bridge, greatly improving its adaptability to different bridge structures. After use, it can be rotated and lowered back into the truck bed of the truck 1 for storage.

[0030] like Figures 3-4 As shown, the bridge construction auxiliary lifting mechanism 2 includes a guide rail frame 201, which is slidably installed in a sliding frame 106. A suspended basket 204 is slidably installed in the guide rail frame 201. The suspended basket 204 is fixedly connected to a wire rope. The wire rope is wound on the outer surface of a winding column 205. The winding column 205 is fixedly installed on the outer surface of the output shaft of a third motor 203. The third motor 203 is fixedly installed on the upper surface of a support frame 202. The support frame 202 is fixedly installed on the upper surface of the guide rail frame 201.

[0031] A second threaded rod 206 is fixedly installed on the lower surface of the guide rail frame 201. A sprocket is threadedly installed on the outer surface of the second threaded rod 206. The sprocket is rotatably installed in two sets of U-shaped frames 208. The two sets of U-shaped frames 208 are fixedly installed on the upper surface of the mounting plate 113. The mounting plate 113 is fixedly installed on the lower surface of the sliding frame 106. A fourth motor 207 is fixedly installed on the upper surface of the mounting plate 113. A sprocket is fixedly installed at one end of the output shaft of the fourth motor 207. A chain is fitted on the outer surface of the sprocket of the fourth motor 207. The other end of the chain is fitted on the outer surface of the sprocket rotating in the U-shaped frame 208. This allows the sprocket to push the second threaded rod 206 through the rotating thread, thereby driving the guide rail frame 201 to slide back and forth in the sliding frame 106.

[0032] Through the design of the guide frame 201, the suspended platform 204, the third motor 203, the winding column 205, the second threaded rod 206, and the fourth motor 207, after vertical and angular rotation, the third motor 203 is activated to drive the sprocket inside the U-shaped frame 208 to perform threaded transmission on the outer surface of the second threaded rod 206. This pushes the second threaded rod 206, causing the guide frame 201 to slide back and forth within the sliding frame 106 to extend its length. Once the guide frame 201 extends the internally slidably mounted suspended platform 204 outside the bridge, the third motor 203 is activated to drive the winding column 205 to wind the wire rope onto the outer surface. The suspension platform 204 is released without traction by releasing the steel wire rope, allowing it to slide down the guide frame 201 to the outer wall of the bridge for workers to paint or perform other treatments. While workers are working on the platform, a driver can also move a truck 1 to different parts of the bridge for workers to carry out their work. This, combined with the extension and lowering functions of the suspension platform 204, enables continuous construction on different parts of the bridge without the need for frequent disassembly and reinstallation of the platform, reducing downtime during construction and further improving construction efficiency.

[0033] Based on the above technical solution, the working steps of this solution are summarized as follows: When in use, the second motor 110 can be started to drive the transmission column 112 to perform threaded transmission on the outer surface of the first threaded rod 105. This allows the transmission column 112 to push the guide plate 104 vertically upward within the guide frame 103 through threaded transmission. This allows the guide plate 104 to drive the guide rail frame 201 and the basket 204, which are slidably installed in the sliding frame 106, to be lifted out of the truck bed of the truck 1 until they are lifted higher than the bridge railing and then stop.

[0034] Then, the first motor 108 can be started to drive the gear 109 to mesh with the transmission gear ring 107 to drive the turntable 102 to rotate within the connecting plate 101. This allows the turntable 102 to drive the guide rail frame 201 and the basket 204, which are slidably installed within the guide frame 103, to rotate at an angle until the basket 204 is rotated to the desired position and then the rotation stops.

[0035] Subsequently, the third motor 203 can be activated to drive the sprocket inside the U-shaped frame 208 to perform threaded transmission on the outer surface of the second threaded rod 206. This pushes the second threaded rod 206 to drive the guide rail frame 201 to slide back and forth within the sliding frame 106, extending its length until the guide rail frame 201 extends the internally slidably mounted suspended basket 204 to the outside of the bridge. Then, the third motor 203 can be activated to drive the winding column 205 to release the wire rope wound on the outer surface. After the wire rope is released, the suspended basket 204 is no longer under traction and can slide down within the guide rail frame 201 to the outer wall of the bridge for workers to perform painting and other treatments. While workers are working, the driver can also drive the truck 1 to move the suspended basket 204 to different parts of the bridge for workers to carry out construction operations. Combining this with the extension and lowering functions of the suspended basket 204, continuous construction of different parts of the bridge can be achieved without the need for frequent disassembly and reinstallation of the suspended basket 204, reducing downtime during construction and further improving construction efficiency.

[0036] In summary, by adjusting the suspended platform 204 in three axes—vertical, rotational, and extension—it can flexibly reach and carry out construction on the complex shapes of the bridge's superstructure, substructure, and sides, greatly improving its adaptability to different bridge structures. Furthermore, after use, it can be rotated and lowered back into the truck bed 1 for storage.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
