Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoisting equipment, in particular to a fixing device used for hoisting a prefabricated T-beam. Background Art
[0002] In the field of construction engineering, prefabricated T-beams are a common and important structural component, widely used in projects such as bridges and tunnels. Prefabricated T-beams are widely favored due to their advantages such as convenient production, short construction period, and reliable quality. However, in the process of hoisting and construction of prefabricated T-beams, traditional hoisting methods often have some problems.
[0003] The traditional method of lifting prefabricated T-beams mainly relies on direct lifting with steel wire ropes. Although this method is simple and direct, it has many shortcomings in practical applications. First, because the steel wire rope acts directly on the bottom of the beam, the bottom of the beam is subjected to concentrated force, which can easily cause local damage to the bottom of the beam and the flange plate. In particular, the shaking and impact that may occur during the lifting process increase the risk of such damage. Once the beam is damaged, it will not only affect its service life and safety, but also make it difficult to repair after the beam is erected, increasing the construction cost and construction period.
[0004] Secondly, the wire rope is also susceptible to wear during the hoisting process, especially in the part in contact with the beam body. Due to friction and extrusion, the wear rate of the wire rope will be accelerated, thus reducing its service life and safety. This not only increases the safety hazards during the construction process, but also the frequent replacement of wire ropes will increase the construction cost. Utility Model Content
[0005] The purpose of the utility model is to provide a fixing device for lifting prefabricated T-beams, so as to solve the problem raised in the above-mentioned background technology that due to the direct action of the steel wire rope on the bottom of the beam body, the bottom of the beam body is subjected to concentrated force, which is easy to cause local damage to the bottom of the beam body and the flange plate position, especially the shaking and impact that may occur during the lifting process, which further increases the risk of such damage.
[0006] To achieve the above-mentioned purpose, the utility model provides a fixing device for lifting prefabricated T-beams, including two first steel plates, which are horizontally arranged and parallel to each other, and second steel plates are installed on the front and rear sides between the two first steel plates, and slots are provided at both ends of the first steel plates, and left-side steel plates are installed on both sides of the left slot, and right-side steel plates are installed on both sides of the right slot, and solid steel bars are installed on the inner side of the slot, and steel wire ropes are connected to the outer side of the middle part of the solid steel bars.
[0007] Preferably, the left steel plate and the right steel plate are both arranged perpendicularly relative to the first steel plate and are welded and fixed to the first steel plate.
[0008] Preferably, the length of the second steel plate is the same as that of the first steel plate, a first positioning hole is formed on the surface of the second steel plate, and the end of the solid steel rod passes through the first positioning hole.
[0009] Preferably, second positioning holes are opened on the surfaces of the left steel plate and the right steel plate, and the ends of the solid steel rods are rotatably connected to the second positioning holes via bearings.
[0010] Preferably, the width of the middle portion of the first steel plate is greater than the width of the two end portions, and a rib is installed on the outer side of the second steel plate between the two first steel plates, and the upper and lower sides of the rib are welded and fixed to the first steel plates.
[0011] Preferably, a plurality of buffer components are installed between the middle parts of the two first steel plates.
[0012] Preferably, the buffer assembly includes a fixed sleeve, a movable column is inserted into one end of the fixed sleeve, a buffer spring is installed inside the fixed sleeve, the outer end of the movable column is welded and fixed to the first steel plate, and the outer end of the fixed sleeve is welded and fixed to another first steel plate.
[0013] Preferably, the buffer components are arranged at equal intervals.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In the fixture for lifting the prefabricated T-beam, the fixture forms a stable frame structure through two first steel plates that are horizontally arranged and parallel to each other, and second steel plates on the front and rear sides, ensuring that the prefabricated T-beam can be stably fixed and supported during the lifting process. This structural design avoids the concentrated force problem caused by the steel wire rope directly acting on the bottom of the beam in the traditional method, and effectively reduces the risk of local damage at the bottom of the beam and the flange plate.
[0016] Secondly, the fixture installs a solid steel bar in the slot and connects it to the solid steel bar through a steel wire rope, achieving uniform distribution of the lifting force. The solid steel bar is rotatably connected to the left and right steel plates through bearings, allowing the prefabricated T-beam to flexibly adjust its posture during the lifting process, reducing shaking and impact, and further reducing the risk of damage to the beam.
[0017] In addition, the fixture also installs several buffer components between the two first steel plates. Through the action of buffer springs, the impact and vibration during the hoisting process are effectively absorbed and alleviated, further improving the stability and safety of the hoisting process. The equidistant arrangement of the buffer components ensures uniform force on the entire device and avoids the problem of local overload. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides a fixing device for lifting prefabricated T-beams, such as Figure 1-Figure 3 As shown, it includes two first steel plates 1, which are horizontally arranged and parallel to each other, and second steel plates 2 are installed on the front and rear sides between the two first steel plates 1. Slots 11 are arranged at both ends of the first steel plates 1, and left steel plates 3 are installed on both sides of the left slot 11, and right steel plates 4 are installed on both sides of the right slot 11, which are used for stable support so that the force of the first steel plate 1 is evenly distributed on the second steel plate 2, the left steel plate 3, and the right steel plate 4. A solid steel bar 6 is installed on the inner side of the slot 11, and a steel wire rope 7 is connected to the outer side of the middle part of the solid steel bar 6 for lifting operations.
[0025] In this embodiment, the left steel plate 3 and the right steel plate 4 are both arranged vertically relative to the first steel plate 1 and are fixed to the first steel plate 1 by welding.
[0026] Specifically, the length of the second steel plate 2 is the same as that of the first steel plate 1 , and a first positioning hole 21 is opened on the surface of the second steel plate 2 . The end of the solid steel rod 6 passes through the first positioning hole 21 to ensure the positioning of the solid steel rod 6 .
[0027] Furthermore, a second positioning hole 31 is opened on the surface of the left steel plate 3 and the right steel plate 4, and the end of the solid steel rod 6 is rotatably connected to the second positioning hole 31 through a bearing, which facilitates the stable rotation of the solid steel rod 6.
[0028] Furthermore, the width of the middle part of the first steel plate 1 is greater than the width of the two end ends, and a rib plate 5 is installed on the outer side of the second steel plate 2 between the two first steel plates 1. The upper and lower sides of the rib plate 5 are welded and fixed to the first steel plate 1 to improve the strength of the front and rear parts and avoid deformation.
[0029] Furthermore, a plurality of buffer components 8 are installed between the middle parts of the two first steel plates 1 to play a buffering role.
[0030] Furthermore, the buffer assembly 8 includes a fixed sleeve 81, one end of which is plugged with a movable column 82, a buffer spring 83 is installed inside the fixed sleeve 81, the outer end of the movable column 82 is welded and fixed to the first steel plate 1, and the outer end of the fixed sleeve 81 is welded and fixed to another first steel plate 1, which has a good buffering effect and avoids deformation of the first steel plate 1 due to uneven pressure during lifting.
[0031] Furthermore, the buffer components 8 are arranged at equal intervals to ensure uniform support and buffering effects.
[0032] When the fixing device for lifting prefabricated T-beams of the utility model is used, firstly, the two first steel plates 1 are placed horizontally and parallel to each other to ensure that the spacing between them is appropriate. Then, the second steel plates 2 are installed on the front and rear sides of the two first steel plates 1, and they are firmly connected to the first steel plates 1 by welding or other fixing methods. Slots 11 are opened at both ends of the first steel plate 1, and the left steel plate 3 and the right steel plate 4 are installed on both sides of the slot 11. These steel plates are also fixed with the first steel plate 1 by welding or other methods to form a stable supporting structure. A solid steel bar 6 is installed on the inner side of the slot 11, and it is ensured that the end of the solid steel bar 6 passes through the first positioning hole 21 on the second steel plate 2, so as to perform precise positioning.
[0033] Second positioning holes 31 are opened on the left steel plate 3 and the right steel plate 4, and the ends of the solid steel rods 6 are rotatably connected to these second positioning holes 31 through bearings, allowing the solid steel rods 6 to make necessary rotations during the hoisting process to adapt to the change in the direction of the hoisting force. A number of buffer components 8 are installed between the middle parts of the two first steel plates 1. Each buffer component 8 consists of a fixed sleeve 81, a movable column 82 and a buffer spring 83. One end of the movable column 82 is welded and fixed to the first steel plate 1, and the other end is inserted into the fixed sleeve 81, and the other end of the fixed sleeve 81 is welded and fixed to another first steel plate 1. During the hoisting process, if the first steel plate 1 is subjected to uneven pressure, the buffer spring 83 will absorb the pressure by compression and extension to prevent the first steel plate 1 from deforming.
[0034] When the prefabricated T-beam needs to be hoisted, the steel wire rope 7 is connected to the middle of the solid steel rod 6. As the hoisting equipment works, the steel wire rope 7 will bear the weight of the prefabricated T-beam and evenly transfer the force to the first steel plate 1, the second steel plate 2, the left steel plate 3 and the right steel plate 4 through the solid steel rod 6 to achieve stable support. At the same time, the buffer assembly 8 will play a buffering role to further reduce the impact and vibration that may occur during the hoisting process.
