Description

Technical Field

[0001] This utility model relates to the field of long steel structure transfer technology, and in particular to a long steel structure transfer device. Background Technology

[0002] Long steel structures refer to steel structural components with large lengths and high load-bearing capacity, widely used in building construction, bridge construction, and heavy equipment manufacturing. These include large I-beams, H-beams, and box girders. These steel structures are characterized by their large weight, long volume, and high transportation difficulty, placing higher demands on handling, transshipment, and installation equipment during actual construction and logistics. As a key piece of equipment in the transportation process, the structural design and functional performance of long steel structure transshipment devices directly affect transshipment efficiency, operational safety, and construction progress.

[0003] In practical applications, especially in the core process of transporting long steel structures, existing steel structure transport equipment has gradually revealed a series of obvious limitations and technical problems when handling long steel structures of different lengths and specifications. For example, utility model patent CN217022546U discloses a portable steel structure handling device, including a base, a support, and a push rod. A transport box is installed on the top of the base, and a hook is installed on the top of the transport box. A U-shaped steel channel is opened on the top side of the transport box, and a steel plate channel is opened in the center of the side of the transport box. A support column is fixedly installed at the bottom of the transport box, and an installation plate is fixedly installed on the top of the outer surface of the support column. Fastening bolts are threaded to the lower surface of the installation plate. This device uses the U-shaped steel channel and the steel plate channel to limit and protect the steel structure, and uses the hook to cooperate with the crane to achieve overall transportation, which improves the safety and convenience of steel structure transport to a certain extent.

[0004] However, existing long steel structure transfer equipment still has significant shortcomings. Specifically, it is not convenient to adjust the support for steel structures of different lengths, and it lacks a telescopic or modular adjustment structure, which limits the applicability of the equipment and makes it difficult to meet the transfer needs of diverse specifications of steel structures on construction sites. In addition, some devices lack sufficient clamping stability for steel structures during transfer, and are prone to slippage or even detachment due to vibration or tilting, affecting transfer efficiency and operational safety. Therefore, in response to the many shortcomings of existing technologies, we urgently need an innovative long steel structure transfer device to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a long steel structure transfer device, which solves the problems in the existing technology that make it inconvenient to adjust and support steel structures of different lengths, lack of telescopic or modular adjustment structure, resulting in limited applicability of the equipment and difficulty in meeting the transfer needs of steel structures of diverse specifications on construction sites.

[0006] To achieve the above objectives, this utility model provides a long steel structure transfer device, including a frame, and side frames that are slidably connected to both sides of the inner side of the frame, and a top plate installed on the top of the frame.

[0007] A cylinder is fixedly connected to the top side of the top plate by bolts, and a pressure plate is provided on the bottom side of the top plate. The output shaft of the cylinder passes through the top of the top plate and is fixedly connected to the pressure plate. A connecting plate is provided on one side of each of the two side frames, and a fixing frame is fitted on both ends of each connecting plate. A buffer frame is fixedly connected to one side of the connecting plate, and a baffle is slidably connected to the inner side of the buffer frame. One side of the baffle is elastically connected to the inner wall of the buffer frame through a buffer pad. Both sides of the baffle are fixedly connected to the inner wall of the buffer frame through dampers.

[0008] Each of the two baffles has a sliding block fixedly connected to both sides, and the sliding block is slidably connected to the inner wall of the buffer frame through a sliding groove.

[0009] Each of the two side frames has a slider fixedly connected to both sides, and all four sliders are slidably connected to the inner wall of the frame through grooves.

[0010] Each of the four sliders has a threaded rod on one side, and the frame and the sliders have threaded grooves that are used to cooperate with the threaded rods. The sliders have several threaded grooves.

[0011] The top plate has two fixed plates on its bottom sides, and the bottom ends of the two plates pass through the top of the frame through slots. Each of the two plates has a rod on one side, and one end of the rod passes through the side wall of the frame and the plate in sequence.

[0012] Each of the two side frames has a base plate fixedly connected to one side of its bottom, and wheels are fixedly connected to both sides of the bottom of the two base plates and to the four corners of the bottom of the frame.

[0013] This utility model discloses a long steel structure transfer device. By incorporating a sliding and adjustable side frame structure, combined with the frame itself as a basic support platform, it achieves flexible adjustment of the steel structure support range, greatly expanding the device's applicability and meeting the transfer needs of diverse steel structures on construction sites. Simultaneously, the baffles within the buffer frame, along with the elastic buffer system formed by buffer pads and dampers, effectively improve the stability and safety of the steel structure's end clamping, preventing slippage or even detachment due to vibration or tilting during transport, thus improving transfer efficiency and operational safety. Furthermore, the cylinder-driven pressure plate pressing method achieves rapid limit control of the steel structure's top, enhancing the uniformity of the overall clamping force distribution and preventing deformation or damage caused by excessive localized force, further ensuring transfer quality. The entire device features a reasonable structural design, simple operation, and strong adaptability. It not only solves the technical problems of poor versatility and unstable clamping in traditional transfer equipment but also significantly reduces the labor intensity of on-site operators, improving the overall efficiency and safety of transfer operations. It fully meets the development needs of modern engineering construction for efficient, intelligent, and safe steel structure transfer equipment and has excellent prospects for widespread application.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A long steel structure transfer device includes a frame 1, and side frames 7 are slidably connected to both sides of the inner side of the frame 1, and a top plate 3 is installed on the top of the frame 1.

[0024] A cylinder 4 is fixedly connected to the top side of the top plate 3 by bolts, and a pressure plate 5 is provided on the bottom side of the top plate 3. The output shaft of the cylinder 4 passes through the top of the top plate 3 and is fixedly connected to the pressure plate 5. A connecting plate 15 is provided on one side of each of the two side frames 7, and a fixing frame 14 is fitted on both ends of the two connecting plates 15. A buffer frame 16 is fixedly connected to one side of the connecting plate 15, and a baffle 17 is slidably connected to the inner side of the buffer frame 16. One side of the baffle 17 is elastically connected to the inner wall of the buffer frame 16 through a buffer pad 18. Both sides of the baffle 17 are fixedly connected to the inner wall of the buffer frame 16 through a damper 19.

[0025] When transferring long steel structures, the positions of the two side frames 7 are first adjusted according to the specific length of the steel structure to be transferred. The operator pulls or pushes the two side frames 7 from the frame 1 in the sliding direction so that the entire support structure can accommodate steel structures of different lengths. After adjustment, the long steel structure to be transferred is placed smoothly on the bearing surface of the frame 1, ensuring that both ends extend into the side frames 7 on both sides. At this time, the baffles 17 in the buffer frames 16 in each side frame 7 will automatically fit the ends of the steel structure under the combined action of the dampers 19 and the buffer pads 18, achieving flexible limiting and shock absorption protection for the steel structure. To prevent the steel structure from shifting or being damaged due to vibration or shaking, the cylinder 4, which is fixed to the top plate 3 by bolts, is activated. Its output shaft drives the pressure plate 5 to move downward. The pressure plate 5 is pressed tightly against the top surface of the steel structure, thus achieving a stable and limited position of the overall steel structure, thereby forming an upper and lower clamping and fixing structure, which further improves the stability during the transportation process. Throughout the process, the sliding fit structure between the side frame 7 and the frame 1, the elastic connection structure between the buffer frame 16 and the baffle 17, and the top pressing structure composed of the cylinder 4 and the pressure plate 5 work together to provide comprehensive support and protection for long steel structures of different lengths and shapes.

[0026] Furthermore, sliding blocks 21 are fixedly connected to both sides of the two baffles 17, and the sliding blocks 21 are slidably connected to the inner wall of the buffer frame 16 through the sliding groove 22. During the transfer process, when the end of the steel structure applies pressure to the baffle 17, the baffle 17 drives the sliding blocks 21 to slide along the sliding groove 22, so that the baffle 17 can automatically adapt to the size of the steel structure. At the same time, under the combined action of the buffer pad 18 and the damper 19, elastic limiting is achieved, which improves the guiding and clamping stability of the baffle 17 and enhances the equipment's adaptability to steel structures of different specifications.

[0027] Furthermore, sliders 8 are fixedly connected to both sides of the two side frames 7, and all four sliders 8 are slidably connected to the inner wall of the frame 1 through the slide grooves 9. When adjusting the position of the side frame 7 relative to the frame 1, the sliders 8 slide along the slide grooves 9, ensuring the guidance and stability of the side frame 7 during movement, avoiding uneven stress on the structure due to offset or jamming, and achieving the effect of improving the overall structural stability and smooth sliding.

[0028] Furthermore, each of the four sliders 8 is provided with a threaded rod 11 on one side, and a threaded groove 10 for use with the threaded rod 11 is provided on one side of the frame 1 and on the slider 8. Several threaded grooves 10 are provided on the slider 8. After the position of the side frame 7 is adjusted, the threaded rod 11 is screwed into the threaded groove 10 on the slider 8, and a suitable position of the threaded groove 10 is selected for fixing, thereby locking the position of the side frame 7 and preventing it from being accidentally displaced during transportation. This achieves the effect of improving the structural adjustment accuracy and the safety of use.

[0029] Furthermore, insert plates 2 are fixedly connected to both sides of the bottom of the top plate 3, and the bottom ends of the two insert plates 2 pass through the top of the frame 1 through slots 6. Each side of the two insert plates 2 is provided with a rod 20, and one end of the rod 20 passes through the side wall of the frame 1 and the insert plate 2 in sequence. When the top plate 3 needs to be adjusted in height or disassembled, the insert plate 2 slides up and down along the slot 6 to achieve a flexible connection between the top plate 3 and the frame 1. At the same time, the rod 20 is inserted into the side wall of the frame 1 and the insert plate 2 to fix the top plate 3 in place. This improves the overall structural adaptability and installation convenience of the device, and enhances the adjustability and maintenance convenience of the equipment.

[0030] Furthermore, a base plate 12 is fixedly connected to one side of the bottom of each of the two side frames 7, and wheels 13 are fixedly connected to the bottom sides of the two base plates 12 and the four corners of the bottom of the frame 1. After the entire transfer device is loaded with steel structure, the operator can push the device to move by the wheels 13 set at the bottom, which improves the mobility of the equipment and the efficiency of on-site operation. At the same time, the base plates 12 fixed at the bottom of the two side frames 7 enhance the structural strength and provide stable support for the wheels 13, thereby achieving the effect of improving the flexibility of transfer and reducing the labor intensity of manual handling.

[0031] In summary:

[0032] In actual operation, the operator first adjusts the two side frames 7 according to the specific length of the long steel structure to be transported. The sliders 8 fixed on both sides of the side frames 7 slide along the grooves 9 on the inner wall of the frame 1, so that the side frames 7 can be pulled or pushed relative to the frame 1, thereby adjusting the span of the entire support structure to accommodate steel structures of different specifications. After the adjustment is completed, the long steel structure to be transported is placed stably on the bearing surface of the frame 1, ensuring that its two ends extend into the side frames 7 on both sides. At this time, the baffles 17 in the buffer frames 16 in each side frame 7 will automatically fit the ends of the steel structure under the combined action of the dampers 19 and the buffer pads 18, realizing flexible limiting and shock absorption protection for the steel structure, and avoiding the steel structure from shifting or being damaged due to vibration or shaking. At the same time, the cylinder 4, which is fixed to the top plate 3 by bolts, is started. Its output shaft drives the pressure plate 5 to move downward. The pressure plate 5 is close to the top surface of the steel structure, realizing the stable limiting of the overall position of the steel structure, thereby forming an upper and lower clamping fixed structure, further improving the stability during the transport process. Based on this, to enhance the guiding and clamping stability of the equipment, sliding blocks 21 are provided on both sides of the baffle 17, and are slidably connected to the inner wall of the buffer frame 16 through sliding grooves 22, so that the baffle 17 can automatically adapt to the steel structure dimensions and maintain a good contact state; to ensure the stability of the side frame 7 during the sliding process, the cooperation between the slider 8 and the sliding groove 9 provides a stable guiding function, preventing the operation efficiency from being affected by deviation or jamming; furthermore, a threaded rod 11 is provided on one side of the slider 8, and works with the frame 1 and multiple threaded grooves 10 on the slider 8, which can be locked after the side frame 7 is adjusted. To prevent accidental displacement during transport, the safety and adjustment accuracy of the equipment are improved. The top plate 3 has insert plates 2 on both sides at the bottom, which pass through the top of the frame 1 through slots 6, allowing for flexible height adjustment. At the same time, the top plate 3 is fixed by inserting rods 20 into the side wall of the frame 1 and the insert plates 2, improving the overall structural adaptability and ease of installation of the device. In addition, the bottom of each of the two side frames 7 is provided with a base plate 12, and wheels 13 are fixedly connected to the bottom of the base plate and the four corners of the frame 1, which facilitates the flexible movement of the entire device after the steel structure is loaded, improving on-site operation efficiency and reducing the intensity of manual handling.By setting up a sliding adjustable side frame 7 structure, combined with the guiding cooperation of slider 8 and slide groove 9, and the locking mechanism of threaded rod 11 and threaded groove 10, the range of steel structure support can be flexibly adjusted, greatly expanding the applicability of the equipment and meeting the transportation needs of steel structures of various specifications on construction sites; the baffle 17 provided in the buffer frame 16, and the elastic buffer system formed by sliding block 21, sliding groove 22, buffer pad 18 and damper 19, effectively improve the stability and safety of the steel structure end clamping, preventing the steel structure from slipping or even falling off due to vibration or tilting during transportation, thus improving transportation efficiency and operational safety; the method of cylinder 4 driving pressure plate 5 to press down realizes the rapid limit control of the top of the steel structure. The design enhances the uniformity of the overall clamping force distribution, preventing deformation or damage to the steel structure caused by excessive local stress, and further ensuring the quality of transfer. The top plate 3 achieves height adjustment and positioning through the insert plate 2, slot 6, and insert rod 20, enhancing the equipment's versatility and ease of maintenance. The cooperation between the bottom plate 12 and the wheel body 13 improves the device's mobility, facilitating flexible on-site scheduling and reducing labor intensity. The overall structure is reasonably designed, easy to operate, and highly adaptable. It not only solves the technical problems of poor versatility and unstable clamping of traditional transfer equipment, but also significantly improves the safety and efficiency of transfer operations, fully meeting the development needs of modern engineering construction for efficient, intelligent, and safe steel structure transfer equipment, and has good prospects for promotion and application.
