Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to an integral hoisting device for the steel reinforcement cage of a cap beam. Background Technology

[0002] In bridge construction projects, the cap beam is a key load-bearing structure connecting the piers and the bridge deck. During the construction of the cap beam, the hoisting of the steel reinforcement cage is one of the core procedures. The cage is usually formed by binding or welding multiple high-strength threaded steel bars. It is large in size and heavy in weight, and needs to be transported to the designated installation position by special hoisting equipment.

[0003] Regarding the aforementioned technologies, the inventors believe that existing hoisting devices, which use ropes and hooks for lifting, suffer from significant drawbacks. Due to the large overall weight of the reinforcing steel frame, the ropes and hooks can only transfer force through the binding points. This immense weight concentrates the force exerted by the ropes on the steel frame at a few binding points, making unsupported areas prone to bending and deformation due to stress imbalance. In severe cases, permanent bending can occur, damaging the structural integrity of the steel frame and rendering it unable to meet the precision and strength requirements of subsequent construction. This necessitates recutting, retying, or welding of the reinforcing steel, increasing construction costs and delaying project progress. Therefore, this invention proposes an overall hoisting device for the reinforcing steel frame of a cap beam. Utility Model Content

[0004] The purpose of this application is to provide an integral hoisting device for the reinforcing steel cage of a cap beam, which improves the situation where the coordination between the hoisting rope and the hook can only achieve force transmission through the binding points. The huge weight will cause the force of the hoisting rope on the reinforcing steel cage to be concentrated at a few binding points. The parts that are not effectively supported are prone to bending deformation due to force imbalance. In severe cases, permanent bending will occur directly, which will not only damage the structural integrity of the reinforcing steel cage, making it unable to meet the accuracy and strength requirements of subsequent construction, but also require the recutting, binding or welding of reinforcing steel, which will increase construction costs and delay the progress of the project.

[0005] This application provides an integral hoisting device for a steel reinforcement cage of a cap beam, including a ground rail and a traveling mechanism slidably mounted on the ground rail. A support beam is fixedly mounted on the traveling mechanism, and a lifting beam is fixedly mounted on the upper end of the support beam. A moving trolley is slidably mounted on the lifting beam. A hoisting device is mounted on the lower end of the moving trolley, and a lifting rope is mounted on the lower end of the hoisting device.

According to the size and weight of the reinforcement framework, the limit screw rod can be adjusted to drive the linkage plates, the connecting plates and the interlocking plate to move in a linked manner, so that the multiple sets of support rods synchronously extend into the interior of the reinforcement framework or abut against the key force-bearing parts thereof, the overall weight is dispersed to a plurality of support points, bending deformation of the unsupported part caused by the weight concentrated on a few binding points is avoided, the structural integrity of the reinforcement framework is guaranteed, no additional rework is required, the construction cost is reduced and the project progress is guaranteed; 2.

[0014] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 This application will be described in further detail below.

[0015] A hoisting device for the integral lifting of the reinforcing steel cage of a cap beam, as described in the following reference. Figure 1 and Figure 2 The system includes a ground rail 1 and a traveling mechanism 2 that is slidably mounted on the ground rail 1. The traveling mechanism 2 includes a drive motor, moving wheels, and other structures, which are existing technologies and will not be described in detail here. It enables the traveling mechanism 2 to move stably on the ground rail 1. A support beam 3 is fixedly mounted on the traveling mechanism 2. A hanging beam 4 is fixedly mounted on the upper end of the support beam 3. The hanging beam 4 has an "I" shaped structure. A moving trolley 5 is slidably mounted on the hanging beam 4. The moving trolley 5 includes a body, moving wheels, drive motor, and other structures, which are existing technologies and will not be described in detail here. It enables the moving trolley 5 to move stably on the hanging beam 4. A hanger 6 is mounted on the lower end of the moving trolley 5. A hanging rope 7 is mounted on the lower end of the hanger 6. The hanger 6 can drive the hanging rope 7 to move vertically up and down.

[0016] like Figure 2 and Figure 3As shown, the lower end of the sling 7 is provided with a lifting assembly 8 for hoisting the reinforcement cage. The lifting assembly 8 includes a lifting frame 81, which is configured in a "Jiong"-shaped structure, has good rigidity and provides stable support. A lifting lug 9 is fixedly arranged on the upper surface of the lifting frame 81, the lifting lug 9 is connected with the sling 7, so that the lifting frame 81 can be stably lifted through the lifting lug 9 and the sling 7. A set of guide frames 82 is fixedly arranged on the upper surface of the lifting frame 81, a support frame 83 is fixedly arranged between the guide frames 82, a limit screw 84 is arranged on the upper surface of the support frame 83 in a threaded penetrating manner, and a handwheel is fixedly arranged at the upper end of the limit screw 84, which facilitates the rotation of the limit screw 84. The lower end of the limit screw 84 is rotatably provided with a connecting block 85 through a bearing, so that the limit screw 84 can drive the connecting block 85 to move vertically up and down. Two ends of the connecting block 85 are rotatably provided with linkage plates 86 through pin shafts, two ends of each linkage plate 86 are rotatably provided with a linkage plate 86, one end of the linkage plate 86 is rotatably connected with a connecting plate 87, the connecting plate 87 is slidably connected with the guide frame 82, so that the connecting plate 87 can be driven by the connecting block 85 and the linkage plate 86 to move horizontally toward or away from each other along the guide frame 82.

[0017] Further, the lifting assembly 8 further comprises a linkage plate 88 fixedly arranged at one end of the connecting plate 87, a plurality of support rods 89 are respectively fixedly arranged on the opposite surfaces of the linkage plate 88, so that the linkage plate 88 can drive the plurality of support rods 89 to move simultaneously. The support rods 89 movably penetrate through the lifting frame 81 to extend into the interior and are fixedly connected with limit blocks 12, and the limit blocks 12 can limit the reinforcement cage and avoid movement during the lifting process.

[0018] Further, a plurality of fixing rings 10 are fixedly arranged at the bottom of the lifting frame 81, a protective steel rope 11 is arranged between the fixing rings 10, and hooks are arranged at both ends of the protective steel rope 11, which can be quickly connected with the fixing rings 10 through the hooks, so as to form protection for the reinforcement cage and prevent it from falling during the lifting process.

[0019] The implementation principle of the embodiment of the present application is as follows: firstly, the traveling mechanism 2 is started to make the traveling mechanism 2 slide along the ground rail 1, driving the support beam 3 and the lifting beam 4 fixed on the traveling mechanism 2 and the mobile trolley 5 on the lifting beam 4 to move synchronously, so that the lifting assembly 8 moves above the reinforcement cage.

[0020] Next, the mobile trolley 5 is started to make the mobile trolley 5 move along the lifting beam 4 to the position directly above the reinforcement cage, then the hanger 6 at the lower end of the mobile trolley 5 is started, the sling 7 is slowly lowered, driving the lifting assembly 8 connected to the lower end of the sling 7 through the lifting lug 9 to move, until the lifting frame 81 of the lifting assembly 8 is accurately positioned above the reinforcement cage.

[0021] Subsequently, the operator rotates the handwheel on the limiting screw 84. Since the limiting screw 84 is threadedly connected to the support frame 83, as the handwheel rotates, the limiting screw 84 moves vertically downwards along the support frame 83. The connecting block 85 at the lower end of the limiting screw 84 moves downwards synchronously, driving the rotating linkage plate 86 at both ends to move. The linkage plate 86 further drives the rotating connecting plate 87, allowing the connecting plate 87 to slide smoothly under the limiting action of the guide frame 82. The connecting plate 87 drives the fixedly connected connecting plate 88 to move synchronously. Multiple sets of support rods 89 on the opposite surface of the connecting plate 88 then move along the through holes of the hoisting frame 81, precisely inserting them between the reinforcing steel reinforcement cages.

[0022] Start the hoist 6, which uses the hoisting rope 7 to move the hoisting lug 9 and the hoisting frame 81 vertically upward. The hoisting frame 81 applies an upward supporting force to the steel reinforcement cage through the support rod 89, causing the support rod 89 to contact the steel reinforcement cage. At this time, rotate the handwheel in the opposite direction. The handwheel drives the limit screw 84 to rotate. The limit screw 84 drives the linkage plate 86 to move through the connecting block 85. The linkage plate 86 drives the support rod 89 on the linkage plate 88 to move horizontally in the opposite direction through the connecting plate 87, causing the support rod 89 to drive the limit block 12 to contact the steel reinforcement cage, preventing movement during hoisting.

[0023] Next, attach both ends of the protective steel rope 11 to the fixing ring 10 to prevent the steel reinforcement cage from falling. Then, restart the hoist 6 to lift the steel reinforcement cage, and then start the traveling mechanism 2 to move it on the ground rail 1 to a suitable position.
