Description

Technical Field

[0001] This utility model relates to the field of steel structure space frame lifting technology, and in particular to a steel structure space frame lifting and fixing device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and is an essential piece of equipment in building construction. With the continuous increase in the height of modern buildings, the height of steel structure space frames during construction is also constantly increasing. To better install steel structure space frames, equipment is needed to lift the space frame to a higher location for installation.

[0003] Existing steel structure space frame lifting devices generally use steel cables for lifting. However, when lifted to a high place, the steel structure space frame is very prone to violent swaying due to the swaying of the lifting steel cables or external factors such as strong winds. This can easily cause it to collide with the building surface or other equipment, resulting in high lifting risk and insufficient stability. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure space frame lifting and fixing device. Identical lifting components are set on both sides in front of the mounting plate. The steel cable is released from the rotating roller and passes through the space between the two guide rollers, the upper sliding cylinder, the middle sliding cylinder and the lower sliding cylinder in sequence, and is connected to the connecting block. After the steel structure space frame is inserted into the two connecting frames and locked from both sides by fastening bolts, the lifting device can be activated to lift the steel structure space frame, so that the lower sliding cylinder slides into the middle sliding cylinder, and the middle sliding cylinder slides up into the upper sliding cylinder, thereby completing the lifting of the steel structure space frame. It is not only highly stable and safe, but also has a simple structure and is convenient and quick to use.

[0005] To achieve the above objectives, a steel structure space frame lifting and fixing device is provided, comprising: a mounting plate, a lifting device, and a rotating roller. A lifting assembly is disposed in front of the mounting plate, and two lifting assemblies are provided, symmetrically distributed left and right. Each lifting assembly includes a connecting plate, an upper sliding cylinder, an upper sliding groove, a middle sliding cylinder, a middle sliding block, a middle sliding groove, a lower sliding cylinder, a lower sliding block, a connecting block, a connecting frame, and fastening bolts. A connecting plate is fixedly connected to the top of the mounting plate. An upper sliding cylinder is fixedly connected to the front side wall of the connecting plate. An upper sliding groove is provided on the inner circumferential surface of the upper sliding cylinder. A middle sliding cylinder is disposed inside the upper sliding cylinder. A middle sliding block is fixedly connected to the circumferential surface of the middle sliding cylinder. A middle sliding groove is provided on the inner circumferential surface of the middle sliding cylinder. A lower sliding cylinder is disposed inside the middle sliding cylinder. A lower sliding block is fixedly connected to the circumferential surface of the lower sliding cylinder. A connecting block is fixedly connected to the bottom of the lower sliding cylinder. A connecting frame is fixedly connected to the bottom of the connecting block. Fastening bolts are threaded onto the left and right side walls of the connecting frame, and two fastening bolts are provided.

[0006] According to the steel structure space frame lifting and fixing device, the lifting assembly further includes reinforcing ribs, side plates and guide rollers. The connecting plate is fixedly connected to the upper sliding cylinder with reinforcing ribs. The top of the connecting plate is fixedly connected with a side plate. There are two side plates, which are symmetrically distributed from left to right. The two side plates are rotatably connected with guide rollers. There are two guide rollers, which are symmetrically distributed from top to bottom.

[0007] According to the steel structure space frame lifting and fixing device, the number of upper sliding grooves is three, and they are evenly distributed inside the upper sliding cylinder. The number of middle sliding blocks is three, and they are evenly distributed on the middle sliding cylinder. The middle sliding blocks are located inside the upper sliding grooves.

[0008] According to the steel structure space frame lifting and fixing device, the number of the middle sliding grooves is set to three and they are evenly distributed inside the middle sliding cylinder, and the number of the lower sliding blocks is set to three and they are evenly distributed on the lower sliding cylinder, with the lower sliding blocks located inside the middle sliding grooves.

[0009] According to the steel structure space frame lifting and fixing device, a lifting device is fixedly connected to the top of the mounting plate, and rotating rollers are fixedly connected to the left and right sides of the lifting device. The number of rotating rollers is set to two, and they are symmetrically distributed on the left and right.

[0010] According to the steel structure space frame lifting and fixing device, the rotating roller is provided with steel cables, and the number of steel cables is two. The end of the steel cable away from the rotating roller passes through the guide roller, the upper slide cylinder, the middle slide cylinder and the lower slide cylinder and is fixedly connected to the top of the connecting block.

[0011] According to the steel structure space frame lifting and fixing device, the upper sliding groove and the middle sliding groove are staggered.

[0012] The above solution has the following advantages: By setting up an installation plate, a lifting device, a rotating roller, and a lifting assembly, and setting up identical lifting assemblies on both sides in front of the installation plate, the steel cable is released from the rotating roller and passes sequentially between the two guide rollers, the upper sliding cylinder, the middle sliding cylinder, and the lower sliding cylinder, and is connected to the connecting block. After the steel structure frame is inserted into the two connecting frames and locked from both sides with fastening bolts, the lifting device can be activated to lift the steel structure frame, thereby causing the lower sliding cylinder to slide into the middle sliding cylinder, and the middle sliding cylinder to slide up into the upper sliding cylinder, thus completing the lifting of the steel structure frame. It not only has high stability and high safety, but also has a simple structure and is convenient and quick to use.

When the lifting device 2 makes the rotating rollers 3 rotate, the steel cables can be released or wound up, thereby using the steel cables to raise and lower the connecting frame 410 below.

[0025] Working principle: Insert the steel structure space frame into the connecting frame 410, and then lock it with the fastening bolts 411. Then start the lifting device 2 to make the rotating rollers 3 on both sides rotate synchronously, so that the lower sliding cylinder 407 slides upward along the middle sliding groove 406. When it slides to the highest position, the lower sliding cylinder 407 drives the middle sliding cylinder 404 to continue to slide upward along the upper sliding groove 403 until the steel structure space frame is lifted to the high position.
