Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a mobile hanger for composite beams. Background Technology

[0002] The existing lifting frames used for transporting composite beams are quite tall. Although the distance between the composite beam and the ground is relatively low after the composite beam is lifted, the length of the lifting rope above the composite beam is relatively long. During the movement, the composite beam located below the lifting rope is prone to swaying, which reduces the maneuverability of the lifting frame itself. At the same time, the swaying composite beam is also more dangerous to transport, making it difficult to meet the usage requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a movable hanger for composite beams, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the movable hanger for the composite beam includes a frame, with support legs provided on both sides and one end of the frame. A roller module is rotatably connected to the lower end of each support leg. A control lever is provided on the roller module at the end of the frame, and a handrail is provided at the upper end of the control lever. The upper surface of the frame has an installation plane, and a support frame is provided above the frame. A winding drum is provided on the installation plane of the frame. A gear reducer is provided on the frame, and a worm gear reducer is provided on one side of the gear reducer. The worm gear reducer drives the winding drum to rotate through the gear reducer. A handwheel is provided at the input end of the worm gear reducer. Two pulleys are respectively provided on the support frame and on both sides of the winding drum. Four fixing rods are provided on the outer surface of the winding drum. A pull rope is also included, with one end of the pull rope forming a loop, and the other end of the pull rope passing over the pulley and connecting to the fixing rod.

[0005] Preferably, the worm gear reducer includes a housing disposed on one side of the gear reducer, a worm wheel and a worm are disposed inside the housing, the input end of the gear reducer is located inside the housing, the worm wheel is disposed on the input end of the gear reducer, one end of the worm extends to the outside of the housing, and a handwheel is disposed on the worm.

[0006] Preferably, the fixing rod has a through hole and a threaded hole that communicates with the through hole. A bolt is installed inside the threaded hole. One end of the pull rope is located inside the through hole on the fixing rod, and the pull rope is fixed in the through hole on the fixing rod by the bolt.

[0007] Preferably, a counterweight is provided at one end of the pull rope that is arranged in a loop.

[0008] Preferably, two of the fixing rods are located on one side of the winding drum, and the other two fixing rods are located on the other side of the winding drum. When the winding drum rotates, all four pull ropes are wound up by the winding drum at the same time.

[0009] The beneficial effects of this utility model are:

[0010] When this type of mobile gantry is in use, the length of the rope extending downwards from the pulley is very low, and the distance between the composite beam and the pulley is also very close. This strictly limits the swing range and amplitude of the composite beam, thereby improving the safety of transporting the composite beam and the stability of the gantry. Furthermore, the device manually controls the lifting and lowering of the composite beam through two sets of reducers, requiring no electricity during use. It is applicable to a wider range of situations and has good performance. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-7As shown, a movable hanger for composite beams includes a frame 1. Support legs 4 are provided on both sides and one end of the frame 1. Roller modules 5 are rotatably connected to the lower ends of the support legs 4. A control lever 6 is provided on the roller module 5 at the end of the frame 1. A handrail 7 is provided on the upper end of the control lever 6. The upper surface of the frame 1 has a mounting plane. A support frame 8 is provided above the frame 1. A winding drum 9 is provided on the mounting plane of the frame 1. A gear reducer 10 is provided on the frame 1. A worm gear reducer is provided on one side of the gear reducer 10. The worm gear reducer drives the winding drum 9 to rotate through the gear reducer 10. A handwheel 11 is provided at the input end of the worm gear reducer. Two pulleys 12 are provided on the support frame 8 and on both sides of the winding drum 9. Four fixing rods 13 are provided on the outer surface of the winding drum 9. A pull rope 14 is also included. One end of the pull rope 14 is arranged in a loop. The other end of the pull rope 14 passes over the pulley 12 and is connected to the fixing rod 13.

[0021] The mobile gantry is used to lift and transfer the composite beam 2. During the preparation of the composite beam 2, hooks 3 are reserved on its surface to facilitate subsequent lifting and transfer of the composite beam 2.

[0022] Before hoisting and transferring the composite beam 2, first move the frame 1 so that the composite beam 2 is inside the frame 1, and align the hooks 3 on the composite beam 2 with the pulleys 12. Then, loop one end of the pull rope 14 is looped onto the hook 3. At this time, the pull rope 14 is in a relatively loose state, making it easy to loop the pull rope 14 onto the hook 3. After all the hooks 3 are looped with pull ropes 14... Start by turning handwheel 11. Through the action of handwheel 11, worm gear reducer, and gear reducer 10, the winding drum 9 can be controlled to rotate. When the winding drum 9 rotates, it can simultaneously wind up the four pull ropes 14. The degree of winding of the four ropes is kept roughly the same to ensure that the composite beam 2 can move upward relatively smoothly. When the distance between the composite beam 2 and the ground is between 3cm and 5cm, the handwheel 11 can be stopped. Due to the one-way self-locking function of the worm gear reducer, the composite beam 2 will not move downward after the handwheel 11 is released, thus ensuring the stability of the composite beam 2 after lifting. After the composite beam 2 is lifted, it can be moved to the predetermined position. After reaching the predetermined position, the composite beam 2 can be moved downward by controlling the reverse rotation of handwheel 11. When the pull ropes 14 are in a relatively loose state, the pull ropes 14 can be removed from the hook 3.

[0023] Both the gear reducer 10 and the worm gear reducer have the function of speed reduction and torque increase to ensure that the heavier composite beam 2 can be lifted. The rotation speed of the handwheel 11 is greater than the output speed of the worm gear reducer, which in turn is greater than the output speed of the gear reducer 10. The output speed of the gear reducer 10 is the same as the rotation speed of the take-up drum 9. At the same time, the take-up drum 9 only needs to rotate 180° from the initial position to tighten the loose rope 14 and keep the distance between the composite beam 2 and the ground between 3cm and 5cm, thereby avoiding serious interference between the ropes 14. When the distance between the composite beam 2 and the ground cannot pass through some potholes, the take-up drum 9 can be rotated another 90° to raise the composite beam 2 to a height of 7cm-10cm above the ground, provided that the interference between the different ropes 14 is minimized.

[0024] The draw rope 14 can be a rope with high tensile strength and not easily deformed, such as nylon rope. The rope may contain steel wire rope to further improve the tensile strength.

[0025] Furthermore, the worm gear reducer includes a housing 15 disposed on one side of the gear reducer 10. A worm gear 16 and a worm 17 are disposed inside the housing 15. The input end of the gear reducer 10 is located inside the housing 15. The worm gear 16 is disposed on the input end of the gear reducer 10. One end of the worm 17 extends to the outside of the housing 15. A handwheel 11 is disposed on the worm 17. The handwheel 11 can drive the worm 17 to rotate. Through the cooperation of the worm 17 and the worm gear 16, the input end of the gear reducer 10 can be driven to rotate. After being transmitted through multiple gears, the input end of the gear reducer 10 drives the output end of the gear reducer 10 to rotate, thereby driving the winding drum 9 to rotate.

[0026] Furthermore, a through hole is provided on the fixing rod 13, and a threaded hole is provided on the fixing rod 13 that communicates with the through hole. A bolt 18 is provided inside the threaded hole. One end of the pull rope 14 is located inside the through hole on the fixing rod 13. The pull rope 14 is fixed in the through hole on the fixing rod 13 by the bolt 18. A rubber layer can be installed on the surface of the pull rope 14 and the rubber layer is located in the through hole. So when the bolt 18 is screwed into the threaded hole on the fixing rod 13, the pull rope 14 can be fixed to the fixing rod 13 through the rubber layer. At the same time, the rubber layer can be replaced with a copper layer or an aluminum layer.

[0027] Furthermore, a counterweight 19 is provided at one end of the pull rope 14 that is in a loop shape, so as to ensure that the end of the pull rope 14 that is away from the winding drum 9 can always hang down from the pulley 12, thereby reducing the displacement of the pull rope 14.

[0028] Furthermore, two of the fixing rods 13 are located on one side of the winding drum 9, and the other two fixing rods 13 are located on the other side of the winding drum 9. When the winding drum 9 rotates, the four pull ropes 14 are simultaneously wound up by the winding drum 9, which can more easily drive the winding drum 9 to rotate.

[0029] The roller module 5 can be rotated by the control lever 6, thereby changing the direction of movement of the hanger. The roller module 5 includes small inflatable tires to improve the smoothness of road passage and provide shock absorption.

[0030] The frame 1 is made of steel pipes and steel plates through welding or fasteners, while the support legs 4 and support frame 8 are also made of steel.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
