Description

Technical Field

[0001] This utility model relates to an auxiliary installation device, and more particularly to an auxiliary installation device for installing a heat insulation plate on the bottom surface of the main beam of a crane, belonging to the field of design and manufacturing technology of protective construction process equipment for metallurgical lifting equipment. Background Technology

[0002] In a steel plant, after slabs are continuously cast, they need to be lifted and stacked using slab cranes. During production, slab cranes are used to load hot slabs into the heating furnace, or to remove returned slabs from the heating furnace. In this situation, as many as eight slab cranes are in operation. Currently, the main beams of the slab cranes operating in this area lack heat radiation protection, and the main beams are subjected to high-temperature heat radiation, severely affecting their service life. It is necessary to install heat insulation plates under the main beams to reduce the impact of heat radiation.

[0003] The method of installing the insulation panels on eight slab cranes by erecting scaffolding is time-consuming, inefficient, and seriously affects production. Currently, there are no other patent documents or related technologies that can guide the rapid installation of insulation panels on these eight slab cranes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary installation device for installing heat insulation panels on the bottom surface of the main beam of a crane crane, which is convenient to operate and has high installation efficiency.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: an auxiliary installation device for installing heat insulation panels on the bottom surface of a gantry crane main beam, including a gantry crane trolley, which is reciprocally arranged on the gantry crane main beam along its length. At least two sets of hooks that can be raised and lowered vertically are arranged on the gantry crane trolley. The auxiliary installation device also includes a multi-functional work platform, a support connection assembly, and a safety protection locking assembly. The multi-functional work platform is detachably and fixedly connected to each set of hooks on the gantry crane trolley through the support connection assembly. The multi-functional work platform, once lifted into position, is locked onto the gantry crane main beam at the corresponding position by the safety protection locking assembly. During the heat insulation panel installation process, the heat insulation panels to be installed are stored at the corresponding positions on the multi-functional work platform. The construction personnel, with the protection in place, use the multi-functional work platform as an operating platform to install the heat insulation panels on the bottom surface of the gantry crane main beam.

[0006] Furthermore, the auxiliary installation device also includes a fall arrestor and a ladder. The ladder is arranged at an angle between the main beam of the overhead crane and the multi-functional work platform. The fall arrestor is detachably fixed at the corresponding position on the main beam of the overhead crane. The safety belts of the construction workers are detachably locked to the fall arrestor.

[0007] The preferred embodiment of the above solution is that the support connection assembly includes multiple sets of wire rope buckle groups, the number of which is equivalent to the number of hooks arranged on the gantry crane trolley. Each set of wire rope buckle groups is fixedly mounted in an isosceles triangle at the corresponding position of the multi-functional work platform with the connection lifting point as the vertex. Each set of wire rope buckle groups is detachably fixedly connected to the corresponding hook through the buckle arranged at the vertex.

[0008] Furthermore, the safety locking assembly includes at least four hand-operated locking hoists, which are symmetrically or evenly distributed along the circumferential direction between the edge of the multi-functional work platform and the corresponding position of the overhead crane main beam.

[0009] The preferred embodiment of the above scheme is that the multi-functional work platform is a rectangular truss platform welded from steel profiles and steel plates. Railings are arranged at each edge of the rectangular truss platform along the circumference. At least one set of wire rope buckles is arranged at each end of the rectangular truss platform along its length. At least one hand-operated locking hoist is arranged at each of the four corners of the rectangular truss platform. During the installation of the heat insulation board, the heat insulation board is stored in the corresponding position on the rectangular truss platform. The construction personnel in protective position use the rectangular truss platform as an operating platform to install the heat insulation board on the bottom surface of the main beam of the overhead crane.

[0010] Furthermore, the auxiliary installation device also includes a truck crane, which, with the cooperation of construction personnel, transfers the required heat insulation panels from the ground to the designated location on the rectangular truss platform in batches according to the required quantity.

[0011] The preferred method of the above scheme is that, during the installation of the insulation board, the rectangular truss platform of the hoist is moved to the next installation position by the trolley of the overhead crane with the cooperation of the main beam of the overhead crane.

[0012] Furthermore, railings are also installed along the length of the main beam of the overhead crane at its outer edge.

[0013] The beneficial effects of this utility model are as follows: The technical solution provided in this application is based on the existing overhead crane trolley, combined with the structural features of the overhead crane trolley being reciprocally movable along the length of the main beam of the overhead crane, and having at least two sets of hooks that can be raised and lowered vertically on the overhead crane trolley. By adding a multi-functional work platform, a support connection assembly, and a safety locking assembly, the auxiliary installation device of this application is constructed. Then, the multi-functional work platform is detachably and fixedly connected to each set of hooks of the overhead crane trolley through the support connection assembly, and the multi-functional work platform is lifted into position. The safety locking components secure the insulation panels to the corresponding positions on the overhead crane main beam. During insulation panel installation, the panels can be stored on the multi-functional work platform. Workers, with safety measures in place, can then use the multi-functional work platform as an operating platform to install the insulation panels on the underside of the overhead crane main beam. This achieves the dual purpose of using the multi-functional work platform for storing the insulation panels and serving as a work platform for installation, completely eliminating the need for a full-span scaffold and then placing platform panels on it. With this auxiliary installation device, the multi-functional work platform is directly positioned under the overhead crane main beam where the insulation panels are to be installed via the overhead crane trolley, completely eliminating the need for scaffolding erection and dismantling after installation. This significantly improves efficiency and greatly enhances construction convenience. After installation, the overhead crane trolley lowers the platform to the workshop floor for quick dismantling and transfer to the next overhead crane for continued installation.

[0018] like Figure 1 , Figure 2 as well as Figure 3This invention provides an auxiliary installation device for installing heat insulation panels on the bottom surface of a gantry crane main beam, offering convenient construction and high installation efficiency. The auxiliary installation device includes a gantry crane trolley 1, which is reciprocally movable along the length of the gantry crane main beam 2. The gantry crane trolley 1 has at least two sets of vertically movable hooks 8. The device also includes a multi-functional work platform, a support connection assembly, and a safety locking assembly. The multi-functional work platform is detachably and fixedly connected to each set of hooks 8 on the gantry crane trolley 1 via the support connection assembly. Once in place, the multi-functional work platform is locked to the corresponding position on the gantry crane main beam 2 by the safety locking assembly. During heat insulation panel installation, the heat insulation panels to be installed are stored at the corresponding positions on the multi-functional work platform. Construction personnel, with safety in place, use the multi-functional work platform as an operating platform to install the heat insulation panels on the bottom surface of the gantry crane main beam. The technical solution provided in this application is based on the existing overhead crane trolley, and further incorporates the structural features of the overhead crane trolley being reciprocally movable along the length of the main beam of the overhead crane, and having at least two sets of vertically adjustable hooks on the trolley. By adding a multi-functional work platform, a support connection assembly, and a safety locking assembly, the auxiliary installation device of this application is constructed. The multi-functional work platform is then detachably and fixedly connected to each set of hooks on the overhead crane trolley via the support connection assembly, and the lifted multi-functional work platform is secured by a safety locking assembly. The locking assembly is secured to the corresponding position of the overhead crane main beam. This allows the insulation panels to be stored on the multi-functional work platform during installation. Then, the workers, with protective gear in place, use the multi-functional work platform as an operating platform to install the insulation panels on the underside of the overhead crane main beam. This achieves the dual purpose of using the multi-functional work platform for storing the insulation panels and serving as a platform for installation, completely eliminating the need for a full-span scaffold and then placing platform panels on it. With this auxiliary installation device, the multi-functional work platform is directly positioned under the overhead crane main beam where the insulation panels are to be installed via the overhead crane trolley, completely eliminating the need for scaffolding and its subsequent dismantling. This not only greatly facilitates the construction operation but also significantly improves installation efficiency. After installation, the overhead crane trolley lowers the platform to the workshop floor for quick dismantling and transfer to the next overhead crane for continued installation.

[0019] Accordingly, to maximize the safety of high-altitude operations and facilitate high-altitude installation work, the auxiliary installation device described in this application also includes a fall arrestor and a ladder 3. The ladder 3 is inclinedly arranged between the main beam 2 of the overhead crane and the multi-functional work platform. The fall arrestor is detachably fixed at the corresponding position on the main beam 2 of the overhead crane, and the safety belts of the construction personnel are detachably locked to the fall arrestor. This allows construction personnel to quickly and conveniently descend from the main beam 2 of the overhead crane to the multi-functional work platform, while the fall arrestor effectively ensures that the construction personnel are securely connected to the main beam 2 of the overhead crane through their safety belts, ensuring absolute safety. Furthermore, considering the site conditions, to facilitate the transfer of the insulation panels, the auxiliary installation device described in this application also includes a truck crane. The insulation panels to be installed are transferred from the ground in batches to the designated positions on the rectangular truss platform 6 using the truck crane, with the cooperation of the construction personnel.

[0020] Furthermore, as a major improvement of this application, in order to ensure both ease of operation and simplification of its structure as much as possible, the support connection assembly of this application includes multiple sets of wire rope buckle groups 4, the number of which is equivalent to the number of hooks 8 arranged on the trolley 1 of the crane. Each set of wire rope buckle groups 4 is fixedly mounted in an isosceles triangle at the corresponding position of the multi-functional work platform with the connection lifting point as the vertex. Each set of wire rope buckle groups 4 is detachably fixedly connected to the corresponding hook 8 through the buckle arranged at the vertex. The safety protection locking assembly of this application includes at least four hand-operated locking hoists 5, which are symmetrically or evenly distributed circumferentially between the edge of the multi-functional work platform and the corresponding position of the main beam 2 of the crane. The multi-functional work platform of this application is a rectangular truss platform 6 welded from structural steel and steel plates. Guardrails 7 are arranged at each edge of the rectangular truss platform 6 along its circumference. At least one set of wire rope buckles 4 is arranged at each end of the rectangular truss platform 6 along its length, and at least one hand-operated locking hoist 5 is arranged at each of the four corners of the rectangular truss platform 6. During the installation of the heat insulation panel, the heat insulation panel is stored in the corresponding position on the rectangular truss platform 6. The construction personnel, in protective positioning, use the rectangular truss platform 6 as an operating platform to install the heat insulation panel on the bottom surface of the overhead crane main beam. Simultaneously, guardrails 7 are also arranged along the outer edge of the overhead crane main beam 2 along its length. In this way, the rectangular truss platform and the overhead crane trolley are securely connected by wire rope buckles, and then locked by hand-operated locking hoists, ensuring the absolute stability and reliability of the connection of the rectangular truss platform during the installation operation. During the specific installation of the insulation board, after the insulation board of one component is installed, the locking hoist 5 is released to release the lock between the rectangular truss platform 6 and the main beam of the overhead crane. Then, with the cooperation of the main beam 2, the trolley 1 of the overhead crane can be easily and quickly moved to the next installation position, and then locked again. The operation is very convenient.

[0021] The technical solution of this application will be further described below through specific embodiments:

[0022] 1) Utilizing the double-hook winch system of the slab crane, the working platform is suspended below the main beam to facilitate the installation of the insulation panels. A truck crane is used to lift the insulation panels into the working platform in batches, followed by manual lifting and installation. The trolley's traveling mechanism extends along the main beam to the new installation position, gradually completing the installation of the main beam insulation panels.

[0023] 2) Prepare the work platform in advance. The work platform is equipped with double sets of hook rope buckles, which are used for protection to prevent the welding wire from coming into contact with it.

[0024] 3) Transport the work platform to the bottom of the slab crane, use the double hooks of the slab crane to hook the work platform, and lift it to the appropriate height for the installation of the heat insulation board;

[0025] 4) A ladder is erected at the position from the main beam of the crane to the working platform. At the base of the railing of the main beam, a hand chain hoist is installed. Hand chain hoists are hung at the four corners of the working platform. In addition to stabilizing the working platform and preventing swaying, it also has the function of secondary protection of the working platform.

[0026] 5) Use a truck crane to lift the insulation panels into the work platform in batches, and then manually lift and transport them to install the insulation panels on the main beam;

[0027] 6) Remove the chain hoist, move the trolley and the work platform together, and install the heat insulation board for the next section of the main beam until the task is completed.

[0028] Example 1

[0029] The installation process for the heat insulation board is as follows:

[0030] 1) Prepare the work platform in advance and transport it to the site by car;

[0031] 2) The slab crane lifts the working platform to a suitable height below the main beam, the trolley moves to one side of the main beam, and the crane power is cut off;

[0032] 3) Install ladders and fall arrestors on the main beam of the crane. Workers wear safety belts and climb the ladders to enter the work platform. At the four corners of the work platform, install four 3t hand-operated hoists, which are attached to the base of the main beam railing to stabilize the work platform and provide secondary protection.

[0033] 4) The truck crane lifts some of the heat insulation panels into the work platform for installation until all the heat insulation panels in the work platform are installed.

[0034] 5) Personnel evacuate the work platform, dismantle the four hand chain hoists, power on the crane, move the trolley, and move the work platform to the new installation location;

[0035] 6) If the crane loses power, continue to install the ladder and hand hoist as required above, and then install the heat insulation board until the heat insulation board of the two main beams is installed.

[0036] 7) Remove the hand chain hoist and ladder, lower the crane to the ground, unhook the crane, and complete the installation of the main beam insulation board of this crane.
