Abstract
Description
Technical Field
[0001] This utility model relates to the field of space frame steel structure construction technology, and specifically to a hoisting device for space frame steel structure construction. Background Technology
[0002] Space frame steel structure is a spatial structure widely used in construction engineering. It is mainly composed of steel pipes, plates and connectors. It is one of the more common structural forms in modern construction engineering. Space frame steel structure engineering is a structure mainly made of steel, and hoisting equipment is required during the installation process.
[0003] Currently, existing hoisting devices cannot ensure force balance when hoisting steel of different lengths, posing a risk of tilting and falling. In addition, it is necessary to temporarily bind and fix the hoisted steel, which is time-consuming, labor-intensive, and inefficient. Utility Model Content
[0004] To address the technical problems in the prior art, this utility model provides a hoisting device for the construction of a space frame steel structure, including a mounting frame and two clamping mechanisms. The two clamping mechanisms are slidably installed at the bottom of the mounting frame and symmetrically arranged about the middle of the mounting frame. Each of the four corners of the top of the mounting frame is provided with lifting rings connected to a lifting device. An auxiliary locking mechanism is also included, comprising a pressure plate, a sliding rod, and two fixing ropes placed within the two clamping mechanisms. The bottom of the pressure plate forms a clamping space for placing steel materials between it and the clamping mechanisms. A connecting through hole is provided in the middle of the mounting frame, and the sliding rod is slidably installed within the connecting through hole. Two guide rings are provided at one end of the clamping mechanism near the bottom, symmetrically arranged below the pressure plate on both sides. The fixing ropes are connected to the lifting device, and both ends of the fixing ropes pass through the two guide rings and are fixedly connected to both sides of the pressure plate. Under the action of the two fixing ropes and the lifting device, the pressure plate moves away from the mounting frame and abuts against the steel materials.
[0005] Furthermore, both ends of the guide ring are rotatably equipped with rollers, and both ends of the fixing rope pass over the rollers and are connected to the lifting equipment and the pressure plate, respectively.
[0006] Furthermore, the mounting bracket has rounded chamfers on both sides.
[0007] Furthermore, a hoisting device for the construction of a space frame steel structure also includes two adjusting ropes, each corresponding to a fixed rope. The fixed rope is connected to the hoisting equipment through the adjusting ropes, and the adjusting ropes are used to adjust the tension of the fixed rope.
[0008] Furthermore, the auxiliary locking mechanism also includes a limiting block and a spring. The limiting block is fixedly installed on the top of the slide rod and located above the mounting frame. The spring is sleeved on the slide rod, and both ends of the spring abut against the top of the limiting block and the top of the mounting frame, respectively. When the lifting equipment is not working, the pressure plate is in contact with the top of the clamping mechanism under the elastic force of the spring.
[0009] Furthermore, a hoisting device for the construction of a space frame steel structure also includes a support mechanism, which includes two support rods and multiple protrusions on the top of the support rods. The bottom of the clamping mechanism has grooves on the sides that are close to each other, and the support rods are slidably installed in the grooves.
[0010] Beneficial effects:
[0011] 1. In this utility model, the two sliding clamping mechanisms can accommodate the hoisting of steel of different lengths and ensure force balance during hoisting. Combined with the setting of pressure plate, sliding rod, two fixing ropes and guide ring, the steel can be directly fixed during hoisting, effectively preventing the steel from shaking and slipping, improving the fixing effect and safety performance. At the same time, there is no need for pre-binding, saving manpower and improving hoisting efficiency. Specifically, during hoisting, the hoisting equipment tauts and moves the fixing rope upward. Combined with the rotation of the guide ring, the fixing rope drives the pressure plate to move closer to the steel and finally abut against the steel. Due to the force of the hoisting equipment, it can be effectively ensured that the fixing rope is always in a taut state throughout the hoisting process, thus ensuring that the pressure plate is always in contact with the steel. After the hoisting is completed, the hoisting equipment lowers the fixing rope to a slack state. At this time, the pressure plate can be easily separated from the steel, thus facilitating the unloading of the steel.
[0012] 2. In this utility model, the setting of the roller shaft can reduce the frictional resistance between the fixing rope and the guide ring, and reduce the wear of the fixing rope; combined with the setting of the rounded chamfer, the frictional resistance between the fixing rope and the mounting frame can be reduced, further reducing the wear of the fixing rope.
[0013] 3. In this utility model, by adjusting the rope, the length between the fixed rope and the lifting equipment can be freely adjusted to ensure that the fixed rope is always taut when the lifting equipment is working. In addition, the displacement of the pressure plate can be adjusted according to the amount of steel to ensure that the steel can always be in contact with the steel.
[0014] 4. In this utility model, by setting the limiting block and the spring, the spring force can be used to realize the automatic reset of the pressure plate, which is convenient for loading and unloading steel. Specifically, when the fixing rope is not subjected to the tension of the lifting equipment, that is, during the loading or unloading process, the pressure plate will be located at the top of the clamping mechanism under the action of the spring force. At this time, the clamping space can be maximized, which is convenient for placing or taking out steel.
[0015] 5. In this utility model, the support mechanism, which includes two support rods and multiple protrusions on the top of the support rods, can easily support the steel, increase the contact area and frictional resistance between the two, further prevent the steel from shaking and slipping, and improve the fixing effect and safety performance.

[0029] This utility model provides a hoisting device for the construction of space frame steel structures, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a mounting frame 1 and two clamping mechanisms 2. The two clamping mechanisms 2 are slidably mounted on the bottom of the mounting frame 1 and are symmetrically arranged about the middle of the mounting frame 1. Each of the four corners of the top of the mounting frame 1 is provided with lifting rings 3 for connecting to lifting equipment. The system also includes an auxiliary locking mechanism, which includes a pressure plate 4, a sliding rod 5, and two fixing ropes 6 placed within the two clamping mechanisms 2. The bottom of the pressure plate 4 forms a clamping space between itself and the clamping mechanism 2 for placing steel. The mounting frame 1 has a connecting through hole in the middle, and the sliding rod 5 is slidably mounted... Within the connecting through hole, the clamping mechanism 2 has two guide rings 7 near its bottom end. The two guide rings 7 are symmetrically arranged on both sides below the pressure plate 4. The fixing rope 6 is connected to the lifting equipment, and both ends of the fixing rope 6 pass through the two guide rings 7 and are fixedly connected to both sides of the pressure plate 4. Under the action of the two fixing ropes 6 and the lifting equipment, the pressure plate 4 moves away from the mounting frame 1 and abuts against the steel. That is, when the lifting equipment leaves the ground, the fixing rope 6 is in a fully taut state. The length of the pressure plate 4 is not less than the length of the mounting frame 1, which improves the fixing effect.
[0030] In this embodiment, the two sliding clamping mechanisms 2 can accommodate the hoisting of steel of different lengths and ensure force balance during hoisting. Combined with the setting of pressure plate 4, sliding rod 5, two fixing ropes 6 and guide ring 7, the steel can be directly fixed during hoisting, effectively preventing the steel from shaking and slipping, improving the fixing effect and safety performance. At the same time, there is no need for pre-binding, saving manpower and improving hoisting efficiency. Specifically, during hoisting, the fixing rope 6 is taut and moved upward by the lifting equipment. Combined with the rotation of the guide ring 7, the fixing rope 6 drives the pressure plate 4 to move closer to the steel and finally abut against the steel. Due to the force of the lifting equipment, it can be effectively ensured that the fixing rope 6 is always taut throughout the hoisting process, thus ensuring that the pressure plate 4 is always in contact with the steel. After the hoisting is completed, the hoisting equipment lowers the fixing rope 6 to a slack state. At this time, the pressure plate 4 can be easily separated from the steel, which facilitates the unloading of the steel.
[0031] In this utility model, preferably, such as Figure 1 , Figure 2 As shown, both ends of the guide ring 7 are rotatably equipped with rollers, and both ends of the fixing rope 6 pass over the rollers and are connected to the lifting equipment and the pressure plate 4 respectively; the two sides of the mounting frame 1 are respectively provided with rounded chamfers. In actual use, in order to reduce frictional resistance, fixed pulleys can also be set on both sides of the mounting frame 1 so that the fixing rope 6 passes over the fixed pulleys and is connected to the guide ring 7 and the pressure plate 4.
[0032] In this embodiment, the frictional resistance between the fixing rope 6 and the guide ring 7 can be reduced by setting the roller shaft, thereby reducing the wear of the fixing rope 6; combined with the setting of the rounded chamfer, the frictional resistance between the fixing rope 6 and the mounting frame 1 can be reduced, further reducing the wear of the fixing rope 6.
[0033] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, a hoisting device for the construction of a space frame steel structure also includes two adjusting ropes, which correspond one-to-one with the fixed rope 6. The fixed rope 6 is connected to the hoisting equipment through the adjusting ropes. The adjusting ropes are used to adjust the tension of the fixed rope 6. In actual use, a partially elastic fixed rope 6 can also be used to achieve adjustment by utilizing the elasticity of the fixed rope 6.
[0034] In this embodiment, by adjusting the rope settings, the length between the fixed rope 6 and the lifting equipment can be freely adjusted to ensure that the fixed rope 6 is always taut when the lifting equipment is working. In turn, the displacement of the pressure plate 4 can be adjusted according to the amount of steel to ensure that the steel can always be in contact with the steel.
[0035] In this utility model, preferably, such as Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary locking mechanism also includes a limiting block 8 and a spring 9. The limiting block 8 is fixedly installed on the top of the slide rod 5 and located above the mounting bracket 1. The spring 9 is sleeved on the slide rod 5, and both ends of the spring 9 abut against the top of the limiting block 8 and the mounting bracket 1, respectively. The limiting can prevent the slide rod 5 from disengaging from the connecting through hole, and can also limit the spring 9. When the lifting equipment is not working, the pressure plate 4 is in contact with the top of the clamping mechanism 2 under the elastic force of the spring 9.
[0036] In this embodiment, by setting the limiting block 8 and the spring 9, the spring force of the spring 9 can be used to realize the automatic reset of the pressure plate 4, which facilitates the loading and unloading of steel. Specifically, when the fixing rope 6 is not subjected to the tension of the lifting equipment, that is, during the loading or unloading process, the pressure plate 4 will be located at the top of the clamping mechanism 2 under the action of the spring force of the spring 9. At this time, the clamping space can be maximized, which is convenient for placing or taking out steel.
[0037] In this utility model, preferably, such as Figure 1 and Figure 4 As shown, a hoisting device for the construction of a space frame steel structure also includes a support mechanism. The support mechanism includes two support rods 10 and a plurality of protrusions 11 set on the top of the support rods 10. The protrusions 11 are made of flexible rubber. The plurality of protrusions 11 are spaced apart along the length of the support rods 10. The height of two adjacent protrusions 11 can be the same or different. The bottom of the clamping mechanism 2 is provided with a sliding groove on the side that is close to each other, and the support rods 10 are slidably installed in the sliding groove.
[0038] In this embodiment, the support mechanism, which includes two support rods 10 and a plurality of protrusions 11 on the top of the support rods 10, can conveniently support the steel, increase the contact area and frictional resistance between the two, further prevent the steel from shaking and slipping, and improve the fixing effect and safety performance. Specifically, the contact area between the support rods 10 and the bottom of the steel can be changed by the sliding of the groove.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
