Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1 to 4 As shown in Embodiment 1, a novel tensioning jack hoisting system includes a self-propelled hanging basket main beam 1, longitudinal beams 2, transverse beams 3, an electric chain hoist 4, and an electric I-beam traveling trolley 5. The two self-propelled hanging basket main beams 1 are symmetrically arranged on the left and right sides, and two sets of first connecting plates 6 are fixedly arranged on the opposite sides of the self-propelled hanging basket main beams 1. Each set of first connecting plates 6 consists of two plates, which are symmetrically arranged front and back. There are two longitudinal beams 2, and a longitudinal beam 2 is arranged above each set of first connecting plates 6. The transverse beam 3 spans the two longitudinal beams 2 and is located below the longitudinal beams 2. The electric I-beam traveling trolley 5 is located between the longitudinal beams 2 and the transverse beams 3, and the electric chain hoist 4 is installed on the transverse beam 3.

[0028] In Embodiment 1, the main beam 1 of the self-propelled hanging basket is bolted to the first connecting plate 6, which is convenient to assemble and occupies little space. Each of the left and right longitudinal beams 2 is equipped with an electric I-beam traveling trolley 5. The bottom of the two electric I-beam traveling trolleys 5 is respectively suspended from both ends of the crossbeam 3. Driving the electric I-beam traveling trolleys 5 allows the crossbeam 3 to move back and forth along the length of the longitudinal beam 2. The chain electric hoist 4 on the crossbeam 3 can lift the tensioning jack and move it left and right on the crossbeam 3. Both the chain electric hoist 4 and the electric I-beam traveling trolley 5 are driven by the motor 12, which saves a lot of manpower, is easy to operate, and the lifting position can be freely adjusted back, forth, left and right, with controllable operation and small error.

[0029] Both the crossbeam 3 and the longitudinal beam 2 are welded from I-beams, and each end of the crossbeam 3 has a lifting plate 7 welded to its top surface for connecting the electric I-beam running trolley 5. Each of the left and right longitudinal beams 2 is equipped with an electric I-beam running trolley 5. The upper end of the electric I-beam running trolley 5 is upside down on the grooved track of the I-beam of the longitudinal beam 2, and the lower end of the electric I-beam running trolley 5 is fixedly connected to the lifting plate 7.

[0030] In Embodiment 1, the electric I-beam running trolley 5 is inverted and placed inside the I-beam groove track of the longitudinal beam 2, which allows the electric I-beam running trolley 5 to more stably drive the crossbeam 3 to move back and forth and adjust the hoisting position. The bottom of the electric I-beam running trolley 5 is bolted to the hoisting plate 7, which makes the connection between the electric I-beam running trolley 5 and the crossbeam 3 more stable and also facilitates disassembly.

[0031] The upper end of the electric chain hoist 4 is hung on the grooved track of the I-beam 3 of the crossbeam, and the lower end of the electric chain hoist 4 has a hook 8 for hoisting the tensioning jack.

[0032] In Example 1, the electric chain hoist 4 has a simple and compact body structure design, which is convenient for installation, disassembly and maintenance, and has good maintainability. At the same time, the electric chain hoist 4 has the characteristics of large and rapid braking torque and low noise, which makes the process of transporting tension jacks faster and speeds up construction efficiency.

[0033] like Figures 5 to 11As shown, in Embodiment 2, the electric H-beam running trolley 5 includes rollers 9, side plates 10, a second connecting plate 11, a motor 12, a support assembly 13, and a rotating assembly 14. The side plates 10 are two steel plates symmetrically arranged on the left and right sides, respectively located on both sides of the longitudinal beam 2. Two sets of rollers 9 are respectively arranged on the opposite surfaces of the two side plates 10. Each set of rollers 9 is located in the grooved track on both sides of the H-beam of the longitudinal beam 2 and can roll along the length of the longitudinal beam 2. The second connecting plate 11 is located between the two side plates 10 and is used to connect the two side plates 10. The second connecting plate 11 is located at the bottom of the longitudinal beam 2. The motor 12 is installed on the outer surface of the right side plate 10. The support assembly 13 is rotatably installed on the bottom ends of the front and rear sides of the side plate 10, respectively. The rotating assembly 14 is rotatably installed on the support assembly 13 on the rear side of the side plate 10.

[0034] In the second embodiment, the bottom of the electric I-beam running trolley 5 is connected to the support assembly 13. When the crossbeam 3 is rotatably connected to the support assembly 13, the weight of the crossbeam 3 can be used to make the support assembly 13 rotate to contact the longitudinal beam 2, so that the crossbeam 3 is more stably clamped at the bottom of the electric I-beam running trolley 5, making the crossbeam 3 more stable during the entire process of adjusting the hoisting position.

[0035] The support assembly 13 includes a connecting rod 13-1, a front rotating rod 13-2, a rear rotating rod 13-3, a rotating wheel 13-4, and a support wheel 13-5. There are two front rotating rods 13-2, symmetrically arranged left and right. There are also two rear rotating rods 13-3, symmetrically arranged left and right. There are two connecting rods 13-1, symmetrically arranged front and rear. The two ends of the front connecting rod 13-1 are fixedly connected to the bottom of the two front rotating rods 13-2, and the two ends of the rear connecting rod 13-1 are fixedly connected to the bottom of the two rear rotating rods 13-3. The two connecting rods 13-1 are rotatably connected to the lifting plate 7. The support wheel 13-5 is located between the two front rotating rods 13-2, and both sides of the support wheel 13-5 are rotatably connected to the top of the two front rotating rods 13-2. The bottom of the front ends of the left and right side plates 10 are respectively fixedly connected to protrusions. Block 5-1, the opposite faces of the two protrusions 5-1 are rotatably connected to the adjacent front rotating rod 13-2 respectively. The protrusions 5-1 are located between the connecting rod 13-1 and the support wheel 13-5. An extension sleeve 5-3 is fixedly connected to the bottom surface of the rear end of the right side plate 10. The extension sleeve 5-3 is rotatably connected to the right rear rotating rod 13-3. A baffle 5-2 is fixedly connected to the bottom surface of the rear end of the left side plate 10. The baffle 5-2 is rotatably connected to the left rear rotating rod 13-3. The rotating wheel 13-4 is located between the top ends of the two rear rotating rods 13-3. The extension sleeve 5-3 and the baffle 5-2 are both located between the rotating wheel 13-4 and the connecting rod 13-1. The top end of the rear rotating rod 13-3 is rotatably connected to the rotating assembly 14. The rotating wheel 13-4 is rotatably connected to the rotating assembly 14. The support wheel 13-5 and the rotating wheel 13-4 are both in contact with the bottom surface of the longitudinal beam 2.

[0036] In Embodiment 2, when the crossbeam 3 is rotatably installed at the bottom of the support assembly 13, the weight of the crossbeam 3 causes the front rotating rod 13-2 and the rear rotating rod 13-3 to deflect upwards simultaneously. At this time, the support wheel 13-5 and the rotating wheel 13-4 simultaneously contact the bottom of the longitudinal beam 2, allowing the longitudinal beam 2, the crossbeam 3, and the support assembly 13 to form a triangular structure. This allows the crossbeam 3 to be stably clamped at the bottom of the electric I-beam running trolley 5. The rotating wheel 13-4 and the support wheel 13-5 can also assist the crossbeam 3 in moving back and forth, ensuring that the crossbeam 3 is in a more stable state during the subsequent adjustment of the hoisting position.

[0037] The rotating assembly 14 includes a first mounting plate 14-1, a fixed plate 14-2, a turntable 14-3, a gear 14-4, a stop block, a slide 14-5, a rack 14-6, a T-block 14-7, and an L-shaped plate 14-8. The first mounting plate 14-1 is located on the rear side of the side plate 10. There are two fixed plates 14-2, which are symmetrically installed on the left and right sides of the top surface of the first mounting plate 14-1. Two rear rotating rods 13-3 are located on the opposite sides of the two fixed plates 14-2, and the top ends of the rear rotating rods 13-3 are rotatably connected to the fixed plates 14-2. The turntable 14-3 is rotatably connected to the first mounting plate 14-1. In the middle, gear 14-4 is located below the first mounting plate 14-1 and is fixedly connected to turntable 14-3. Rotating wheel 13-4 is located above turntable 14-3 and is fixedly connected to turntable 14-3. Slide groove 14-5 is opened on the bottom surface of the front end of the first mounting plate 14-1. A rack 14-6 is provided below slide groove 14-5. The rack 14-6 meshes with gear 14-4. A T-shaped block 14-7 is fixedly connected to the top surface of rack 14-6. T-shaped block 14-7 can slide in slide groove 14-5. An L-shaped plate 14-8 is fixedly connected to the bottom surface of the right end of rack 14-6.

[0038] In Embodiment 2, the front rotating rod 13-2 and the rear rotating rod 13-3 are always pulled down by the gravity of the crossbeam 3, so that the rotating wheel 13-4 is always pressed against the bottom of the longitudinal beam 2. When the rack 14-6 moves to the right, it drives the turntable 14-3 on the gear 14-4 to rotate 90 degrees along its own circumference, which can make the axial direction of the rotating wheel 13-4 rotate from a state perpendicular to the longitudinal beam 2 to a state parallel to the longitudinal beam 2. When the axial direction of the rotating wheel 13-4 is parallel to the longitudinal beam 2, the rotating wheel 13-4 can obstruct the forward and backward movement of the electric I-beam running trolley 5. It can ensure that when the chain electric hoist 4 lifts the tensioning jack, the electric I-beam running trolley 5 on the longitudinal beam 2 needs to be in a stationary state. By adjusting the orientation of the rotating wheel 13-4, the rotating wheel 13-4 has a certain degree of locking effect on the electric I-beam, preventing the electric I-beam running trolley 5 from shaking during transportation.

[0039] A second mounting plate 15 is fixedly connected above the motor 12 at the rear end of the electric chain hoist 4. A first lifting groove 15-1 is provided on the left side of the top surface of the second mounting plate 15. A lifting plate 15-2 is slidably arranged in the first lifting groove 15-1. A spring 17 is provided between the first lifting groove 15-1 and the lifting plate 15-2. A triangular plate 15-3 and a first trapezoidal plate 15-4 are provided above the lifting plate 15-2. A second trapezoidal plate 15-5 is fixedly connected to the right side of the top surface of the second mounting plate 15. A third trapezoidal plate 15-6 is fixedly connected to the front end of the vertical plate. The inclined surface of the second trapezoidal plate 15-5 faces to the right, and the inclined surface of the third trapezoidal plate 15-6 faces to the left. The right side of the first trapezoidal plate 15-4 can contact the left side of the L-shaped plate 14-8, and the left side of the second trapezoidal plate 15-5 can contact the right side of the horizontal straight plate of the L-shaped plate 14-8.

[0040] In Embodiment 2, when the rotating wheel 13-4 is parallel to the longitudinal beam 2, the L-shaped plate 14-8 at the bottom of the rack 14-6 is located on the right side of the extension sleeve 5-3. The electric chain hoist 4 drives the second mounting plate 15 to move to the left, so that the left vertical plane of the second trapezoidal plate 15-5 contacts the right side of the horizontal straight plate of the L-shaped plate 14-8. This causes the second trapezoidal plate 15-5 to push the L-shaped plate 14-8 to drive the rack 14-6 to slide to the left, so that the gear 14-4 rotates and the rotating wheel 13-4 rotates, thus achieving the effect of switching the orientation of the rotating wheel 13-4. This realizes the switching of the state of the rotating wheel 13-4 by using the electric chain hoist 4 to drive the rotating wheel 13-4.

[0041] When the rear rotating rod 13-3 rotates upward, it drives the first mounting plate 14-1 to move upward. Since the front plane of the first mounting plate 14-1 is in contact with the plane of the back of the baffle 5-2 and the extension sleeve 5-3, the first mounting plate 14-1 is always in a horizontal state. At the same time, the L-shaped plate 14-8 is also in a horizontal state, so that the first trapezoidal plate 15-4 and the second trapezoidal plate 15-5 can contact the L-shaped plate 14-8, ensuring that the rotating wheel 13-4 can rotate.

[0042] The bottom of the extension sleeve is provided with a second lifting groove 16, and a lower extension plate 16-1 is slidably connected in the second lifting groove 16. An extension rod 16-2 is fixedly connected to the front side of the lower extension plate 16-1. A spring 17 is connected between the second lifting groove 16 and the lower extension plate 16-1. The extension rod 16-2 can contact the inclined surface of the third trapezoidal plate 15-6.

[0043] In Embodiment 2, when the rotating wheel 13-4 is axially parallel to the longitudinal beam 2, the L-shaped plate 14-8 at the bottom of the rack 14-6 is located on the right side of the extension sleeve 5-3 and is blocked by the lower extension plate 16-1, preventing it from moving to the left. This allows the rotating wheel 13-4 to stably maintain its axial parallelness to the longitudinal beam 2. When the electric chain hoist 4 moves the tensioning jack to the left, the triangular plate 15-3 on the second lifting plate 15-2 first contacts the L-shaped plate 14-8. Due to the pressure of the inclined surface, the lifting plate 15-2 moves downward through the L-shaped plate 14-8. At this time, the third trapezoidal plate 15-6 contacts the extension rod 16-2. The inclined surface of the third trapezoidal plate 15-6 contacts the outer surface of the extension rod 16-2, causing the lower extension plate 16-1 to rise. This allows the second trapezoidal plate 15-5 to push the L-shaped rod, causing the rotating wheel 13-4 to rotate, making the axial direction of the rotating wheel 13-4 perpendicular to the longitudinal beam 2.

[0044] When the electric chain hoist 4 moves to the right, the right side plane of the first trapezoidal plate 15-4 contacts the left side of the horizontal section of the L-shaped plate 14-8, allowing the first trapezoidal plate 15-4 to push the L-shaped plate 14-8 to the right. During this process, the inclined surface of the triangular plate 15-3 contacts the baffle 5-2, causing the triangular plate 15-3 to move downward, thereby causing the lifting plate 15-2 to move downward and compress the spring 17. The left inclined surface of the lower extension plate 16-1 contacts the inclined surface of the second trapezoidal plate 15-5. This causes the lower extension plate 16-1 to rise, allowing the L-shaped plate 14-8 to pass through it. When the L-shaped plate 14-8 is pushed to the right side of the lower extension plate 16-1 by the first trapezoidal plate 15-4, the lifting plate 15-2 moves downward, so that the first trapezoidal plate 15-4 is now just below the L-shaped plate 14-8 and can pass over it. The electric chain hoist 4 continues to move to the right, away from the rotating component 14. At this time, the rotating wheel 13-4 has switched to a state where its axis is parallel to the longitudinal beam 2. This ensures that when the electric chain hoist 4 is transporting on the crossbeam 3, the electric I-beam running trolley 5 is in a locked state. When the electric chain hoist 4 lifts the tensioning jack and transports the equipment to its position, the electric I-beam running trolley 5 is unlocked, and only then can the front and rear positions of the hoisting be adjusted.

[0045] Compared to Embodiment 1, Embodiment 2 only requires the installation of a support assembly 13 and a rotating assembly 14 under the electric I-beam running trolley 5 at one end. This achieves stable clamping of the crossbeam 3 while ensuring that the electric I-beam runs stably and stationary without shaking during rapid transportation, thereby improving transportation efficiency and stability, and increasing the overall safety factor.

[0046] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
