Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a hanging basket sling adjustment device. Background Technology

[0002] In bridge construction, especially in the cantilever construction of long-span bridges, the formwork is a crucial piece of construction equipment. Its main function is to provide a working platform for pouring concrete for the cantilever section of the bridge and to bear various loads during construction. The formwork slings are vital components connecting the formwork to the main bridge structure, playing an indispensable role in ensuring the stability and precise positioning of the formwork and withstanding the enormous tensile forces during construction.

[0003] Traditional hanging basket sling adjustment methods have many technical limitations. On the one hand, their transmission systems are often relatively simple, making it difficult to achieve precise micro-stroke adjustments. In bridge construction, the requirements for the horizontality, verticality, and overall alignment of the hanging basket are extremely high. For example, in the construction of high-speed railway bridges, alignment deviations need to be controlled within a very small range, and traditional adjustment methods cannot meet this high-precision requirement. On the other hand, traditional adjustment devices are insufficient in terms of stability. Therefore, we propose a hanging basket sling adjustment device to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a hanging basket strap adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hanging basket sling adjustment device includes: a support frame, a sling body slidably mounted inside the support frame, a fixed plate fixedly mounted inside the support frame, four sets of guide rods fixedly mounted on the top of the fixed plate, a movable plate fixedly mounted on the outer side of the four sets of guide rods, the movable plate slidably mounted inside the support frame, two sets of threaded sleeves fixedly mounted on the bottom of the movable plate, each set of threaded sleeves having a screw threadedly connected inside, the two sets of screws rotatably mounted inside the fixed plate, each set of screws having a worm gear fixedly mounted at one end, a mounting base fixedly mounted on the bottom of the fixed plate, a rotating rod rotatably mounted inside the mounting base, two sets of worm gears fixedly mounted on the outer side of the rotating rod, multiple sets of sling holes opened inside the sling body, two sets of sling holes respectively having a pin 1 and a pin 2 movably inserted inside, and a lifting ring hole opened at the top of the sling body.

[0007] Preferably, two sets of locking frames II and one set of fixing frames II are fixedly installed on the top of the support frame, and two sets of locking frames I and one set of fixing frames I are fixedly installed on the top of the movable plate. The two sets of locking frames I and the two sets of locking frames II are all arranged on both sides of the sling body. An electric push rod I is fixedly installed on one side of the fixing frame I, and an electric push rod II is fixedly installed on one side of the fixing frame II. A pin is fixedly installed on the output end of the electric push rod I, and a pin is fixedly installed on the output end of the pin II.

[0008] Preferably, a motor is fixedly mounted on one side of one of the mounting bases, and one end of the rotating rod is fixedly mounted on the output end of the motor.

[0009] Preferably, the two sets of worm gears mesh with the corresponding worms, and the fixed plate has two sets of sliding holes inside, with the two sets of screws rotatably installed in the corresponding sliding holes.

[0010] Preferably, a limiting groove is provided at the top of the support frame, and the four sets of limiting rods are slidably installed in the corresponding limiting grooves.

[0011] Preferably, the inside of both sides of the support frame, the inside of the movable plate and the fixed plate are provided with sliding grooves, and the sling body is slidably installed in the sliding grooves.

[0012] In this utility model, a sling adjustment device for a hanging basket is described. By setting a lifting ring hole at the top of the sling, the sling body is hoisted. An electric push rod drives a pin to disengage from the locking frame and the corresponding sling hole. An electric push rod drives a pin to disengage from the locking frame and the corresponding sling hole, thereby releasing the fixation of the sling body. The sling can then be adjusted significantly through the lifting ring hole. This effectively prevents serious accidents such as the hanging basket tipping or falling due to the instability of the sling when moving large and heavy structures like hanging baskets, ensuring the safety of hanging basket construction.

[0013] This utility model features a reasonable structural design. An electric push rod drives a pin to disengage from the locking bracket and the corresponding sling hole. A motor then drives a rotating rod and a worm gear to rotate, which in turn drives two sets of worm wheels to rotate synchronously. This, in turn, drives two sets of screws to rotate within the fixed plate. Through the threaded connection between the screws and the threaded sleeve, the moving plate moves up and down within the support frame under the constraint of the guide rod. The movement of the moving plate, along with the locking frame and pin at the top of the moving plate, fixes the sling, allowing for minor adjustments to the sling's travel within the support frame. Once adjusted to the designated position, the electric push rod drives the pin to engage with the sling hole and locking frame to secure the sling body. The worm gear drive provides a large transmission ratio and self-locking during transmission. During the use of the hanging basket, this effectively prevents the sling from unexpectedly extending or retracting due to device instability, ensuring construction safety and accuracy. The locking frame and pin effectively limit the sling's displacement, ensuring its stable position within the support frame and protecting the safety of the hanging basket and construction personnel.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3A hanging basket strap adjustment device includes: a support frame 1, a strap body 2 slidably installed inside the support frame 1, a fixing plate 3 fixedly installed inside the support frame 1, four sets of guide rods 13 fixedly installed on the top of the fixing plate 3, a movable plate 11 fixedly installed on the outer side of the four sets of guide rods 13, the movable plate 11 slidably installed inside the support frame, and two sets of threaded sleeves 10 fixedly installed on the bottom of the movable plate 11, each set of threaded sleeves 10 having a threaded connection inside. The rod 9, two sets of screws 9 are rotatably installed inside the fixed plate 3, and a worm gear 8 is fixedly installed at one end of each set of screws 9. The bottom of the fixed plate 3 is fixedly installed with a mounting base 4. A rotating rod 6 is rotatably installed inside the mounting base 4. Two sets of worm gears 7 are fixedly installed on the outside of the rotating rod 6. Multiple sets of sling holes 17 are opened inside the sling body 2. Pin 16 and pin 21 are movably inserted into the two sets of sling holes 17 respectively. A lifting ring hole 18 is opened at the top of the sling body 2.

[0020] In this embodiment, two sets of locking frames 22 and one set of fixing frames 20 are fixedly installed on the top of the support frame 1. Two sets of locking frames 12 and one set of fixing frames 14 are fixedly installed on the top of the movable plate 11. The two sets of locking frames 12 and the two sets of locking frames 22 are all arranged on both sides of the sling body 2. An electric push rod 15 is fixedly installed on one side of the fixing frame 14, and an electric push rod 19 is fixedly installed on one side of the fixing frame 20. A pin 16 is fixedly installed on the output end of the electric push rod 15, and a pin 21 is fixedly installed on the output end of the pin 21. By fixing the locking frames 12 on both sides, the positional accuracy of the sling in the vertical and horizontal directions can be ensured, providing a stable foundation for subsequent precise adjustment.

[0021] In this embodiment, a motor 5 is fixedly installed on one side of one set of mounting bases 4, and one end of the rotating rod 6 is fixedly installed on the output end of the motor 5, which effectively avoids adjustment failure due to insufficient power.

[0022] In this embodiment, two sets of worm gears 8 mesh with the corresponding worm 7, and two sets of sliding holes are provided inside the fixing plate 3, with two sets of screws 9 rotatably installed in the corresponding sliding holes.

[0023] In this embodiment, a limiting groove is provided on the top of the support frame 1, and four sets of limiting rods are slidably installed in the corresponding limiting grooves. This transmission method with a large transmission ratio can ensure that the rotation angle of the screw 9 is small enough, thereby driving the moving plate 11 to achieve precise micro-displacement, which meets the high-precision adjustment requirements of the hanging basket position during construction.

[0024] In this embodiment, grooves are provided inside both sides of the support frame 1, inside the movable plate 11 and the fixed plate 3. The sling body 2 is slidably installed in the groove. The stable movement path can ensure that the sling moves in the expected direction, avoiding the impact of sling swaying on the adjustment accuracy, thereby achieving precise control of the hanging basket position.

[0025] In this embodiment, during use, the sling body 2 is hoisted by setting a lifting eyelet hole 18 at the top of the sling. The electric push rod 15 is activated to drive the pin 16 to disengage from the locking frame 12 and the corresponding sling hole 17. The electric push rod 15 is activated again to drive the pin 16 to disengage from the locking frame 12 and the corresponding sling hole 17, thereby releasing the fixation of the sling body 2. Then, the sling can be adjusted significantly through the lifting eyelet hole 18.

[0026] The electric push rod 15 is activated, causing the pin 16 to disengage from the locking bracket and the corresponding sling hole 17. This activates the motor 5, which drives the rotating rod 6 to rotate, thereby driving the two sets of worm gears 7 to rotate. Through the meshing between the worm wheel 8 and the worm gear 7, the two sets of worm wheels 8 rotate synchronously, thereby driving the two sets of screws 9 to rotate within the fixed plate 3. Through the threaded connection between the screws 9 and the threaded sleeve 10, the moving plate 11 is driven to move up and down within the support frame 1 under the restriction of the guide rod 13. The movement of the moving plate 11 and the fixing of the sling by the locking bracket 12 and the pin 16 at the top of the moving plate 11 allow for slight adjustment of the sling's travel within the support frame 1.
