Abstract
Description
Technical Field
[0001] This utility model belongs to the field of T-beam hoisting technology, specifically relating to a movable T-beam hoisting device. Background Technology
[0002] In road and bridge construction, precast T-beams need to be hoisted. The conventional hoisting method is to first pass the wire rope loops through the reserved holes on the upper wing of the T-beam, then pass them around the bottom of the precast T-beam, and then pass them out through the reserved holes on the other side of the upper wing of the precast T-beam. Finally, the loops at both ends of the wire rope are hung on the hook of the crane in a bottom-catching manner, and then the hoisting can begin.
[0003] Currently, existing traditional T-beam lifting tools are difficult to insert the lifting rings due to the large diameter of the wire ropes, which is not only time-consuming and labor-intensive, but also increases the labor intensity of construction workers. During the lifting process, the stability of the T-beam is poor, and the use of large-diameter wire ropes for lifting is costly and has a short service life. Therefore, we propose a T-beam movable lifting tool. Utility Model Content
[0004] The purpose of this utility model is to provide a T-beam movable lifting device to solve the existing problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a T-beam movable lifting device, comprising a lifting beam, a movable shaft, and a load-bearing plate. The lifting beam has a U-shaped structure. Movable shafts are provided at both ends of the bottom of the lifting beam. The middle part of the movable shaft is movably connected to the lifting beam through a first rotating shaft. A load-bearing plate is provided at one end of the movable shaft extending to the inner side of the lifting beam. The load-bearing plate and the movable shaft are integrally formed. A second rotating shaft is provided at the other end of the movable shaft. A connecting block is sleeved on the outer periphery of the middle part of the second rotating shaft. Grooves are provided on the outer sides of both ends of the lifting beam. A hydraulic cylinder is movably connected to the top of the inner end of the groove through a movable connecting seat. The bottom end of the hydraulic rod of the hydraulic cylinder is fixedly connected to the connecting block.
[0006] Preferably, a sleeve is fixedly installed on the inner top wall of the lifting beam corresponding to the position of the load-bearing plate. A pressure rod is slidably arranged inside the sleeve. A pressure plate is fixedly welded to the bottom of the pressure rod. A compression spring is arranged inside the sleeve. The two ends of the compression spring are fixedly connected to the inner top wall of the sleeve and the top of the pressure rod, respectively.
[0007] Preferably, a rubber pad is provided on the top surface of the load-bearing plate, and the rubber pad is fixedly installed on the top surface of the load-bearing plate by adhesive bonding.
[0008] Preferably, the inner wall surfaces on both sides of the sleeve are provided with limiting grooves, and the top ends of the pressure rod are provided with limiting blocks on both sides. The pressure rod is slidably connected to the inner side of the sleeve through the limiting grooves and limiting blocks.
[0009] Preferably, the top of the lifting beam is provided with multiple lifting ropes, and the bottom ends of the lifting ropes are fixedly connected to the lifting beam.
[0010] Preferably, the bottom ends of the plurality of lifting ropes are provided with anti-tangling blocks, and the plurality of lifting ropes pass through the anti-tangling blocks and are fixedly connected thereto.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. By improving the traditional wire rope hoisting method to beam hoisting, a hydraulic cylinder is used to push a hydraulic rod, causing the movable shaft to rotate. This rotates the load-bearing plate to a near-vertical position. When hoisting the T-beam, simply release the hoisting rope, allowing the beam to lower with the load-bearing plate. The load-bearing plate is then positioned on both sides below the T-beam. The hydraulic cylinder then drives the hydraulic rod to retract, lifting the load-bearing plate onto the T-beam, thus achieving rapid hoisting.
[0013] 2. By installing sleeves, pressure rods, and pressure plates on the inner top wall of the lifting beam, and in conjunction with compression springs, the T-beam is clamped during hoisting, ensuring its stability and preventing it from swaying. Attached Figure Description

Detailed Implementation
[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. 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.
[0019] Please see Figure 1-3 This utility model provides a T-beam movable lifting device technical solution: including a lifting beam 1, a movable shaft 4, and a load-bearing plate 5. The lifting beam 1 has a U-shaped structure. Movable shafts 4 are provided at both ends of the bottom of the lifting beam 1. The middle part of the movable shaft 4 is movably connected to the lifting beam 1 through a first rotating shaft 7. A load-bearing plate 5 is provided at one end of the movable shaft 4 extending to the inner side of the lifting beam 1. The load-bearing plate 5 and the movable shaft 4 are integral structures. A second rotating shaft 8 is provided at the other end of the movable shaft 4. A connecting block 9 is sleeved on the outer periphery of the middle part of the second rotating shaft 8. Grooves are provided on the outer sides of both ends of the lifting beam 1. A hydraulic cylinder 10 is movably connected to the top of the inner end of the groove through a movable connecting seat 11. The bottom end of the hydraulic rod of the hydraulic cylinder 10 is fixedly connected to the connecting block 9.
[0020] Specifically, a sleeve 12 is fixedly installed on the inner top wall of the lifting beam 1 at the position corresponding to the load-bearing plate 5. A pressure rod 13 is slidably arranged inside the sleeve 12. A pressure plate 14 is fixedly welded to the bottom of the pressure rod 13. A compression spring 15 is arranged inside the sleeve 12. The two ends of the compression spring 15 are fixedly connected to the inner top wall of the sleeve 12 and the top of the pressure rod 13, respectively.
[0021] Specifically, a rubber pad 6 is provided on the top surface of the load-bearing plate 5, and the rubber pad 6 is fixedly installed on the top surface of the load-bearing plate 5 by adhesive bonding.
[0022] Specifically, the inner wall surfaces on both sides of the sleeve 12 are provided with limiting grooves 16, and the top two sides of the pressure rod 13 are provided with limiting blocks 17. The pressure rod 13 is slidably connected to the inner side of the sleeve 12 through the limiting grooves 16 and the limiting blocks 17.
[0023] Specifically, the top of the lifting beam 1 is provided with multiple lifting ropes 2, and the bottom ends of the lifting ropes 2 are fixedly connected to the lifting beam 1.
[0024] Specifically, the bottom ends of the multiple suspension ropes 2 are provided with anti-tangling blocks 3, and the multiple suspension ropes 2 pass through the anti-tangling blocks 3 and are fixedly connected to them.
[0025] In this embodiment, during use, when the T-beam needs to be hoisted, the hoisting rope 2 is released by the hoisting equipment. At the same time, the hydraulic cylinder 10 drives the bottom hydraulic rod to retract, causing the connecting block 9 at the bottom of the hydraulic rod, along with the movable shaft 4, to rotate around the first rotating shaft 7. This causes the load-bearing plate 5 to rotate, gradually bringing it closer to a vertical state so that the top of the T-beam can enter the inner side of the hoisting beam 1. After the top of the T-beam is completely inside the hoisting beam 1, the hydraulic rod at the bottom of the driving hydraulic cylinder 10 extends downward, pushing the movable shaft 4 to rotate and reset, thereby allowing the load-bearing plate 5 to... The two protruding parts at the top of the T-beam make contact, and under the action of the hydraulic cylinder 10, the load-bearing plate 5 lifts the T-beam. At the same time, during the flipping process of the load-bearing plate 5, the T-beam is lifted up, so that the top of the T-beam contacts the pressure plate 14, and pushes the pressure plate 14 to lift the pressure rod 13, causing the pressure rod 13 to retract into the sleeve 12, thereby compressing the compression spring 15. The reverse force of the compression spring 15 is used to press the top of the T-beam, and together with the rubber pad 6 on the load-bearing plate 5, it serves as an anti-slip measure, thereby ensuring the stability of the T-beam during the hoisting process.
[0026] Although embodiments of the present invention 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 the present invention, the scope of which is defined by the appended claims and their equivalents.
