Description

Technical Field

[0001] This utility model relates to the technical field of transport lifting beams, specifically SPMT combined detachable transport lifting beams. Background Technology

[0002] SPMT is a highly specialized heavy transport equipment, also known as a self-propelled modular transporter. It is generally composed of a lower axle module and an upper transport beam. It can transport heavy goods. Due to its strong load-bearing capacity and multi-degree-of-freedom movement, it has become the core equipment for the transportation and erection of large bridge precast beams (such as box girders and T-beams). The traditional SPMT transport beam lifting process combines multiple axle modules to form a load-bearing platform, uses a hydraulic system to lift the beam and transport it to the bridge site, and realizes efficient and high-precision heavy beam construction.

[0003] Existing transport beams typically consist of support legs at the bottom of a carrying platform. Currently, conventional transport beam structures on the market are relatively simple, with a limited number of legs and a fixed layout. When transporting oversized or heavy cargo, they suffer from insufficient load-bearing capacity and poor stability. Especially during transport, in complex conditions such as uneven load distribution, the beams are prone to deformation or even damage, compromising transport safety. To address these issues, we offer the SPMT modular detachable transport beam. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes an SPMT combined detachable transport beam, which effectively solves the problems of insufficient load-bearing capacity and poor stability of traditional beams by setting up support plates and sliding mechanisms. In particular, when encountering complex working conditions such as uneven load distribution during transportation, the beam is prone to deformation or even damage, affecting transportation safety.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an SPMT modular detachable transport lifting beam, comprising a support platform, with multiple hydraulic lifting components disposed below the support platform for supporting the support platform, and a connecting component disposed between the hydraulic lifting components and the support platform; the connecting component includes a support plate, the upper surface of which is fixedly connected to the support platform, a sliding groove formed on the inner wall of the support plate, and a sliding mechanism disposed on the inner wall of the sliding groove, the lower part of which is connected to the hydraulic lifting components; a limiting mechanism is disposed on the side of the support plate, and a power mechanism is disposed outside the limiting mechanism.

[0008] Furthermore, the sliding mechanism includes a mounting plate, the outer surface of which is slidably connected to a support plate, the lower surface of which is fixedly connected to a hydraulic lifting assembly, and pins fixedly connected to both sides of the mounting plate.

[0009] Furthermore, the outer surface of the pin is slidably connected to the sliding groove, and the end of the support plate is provided with an installation port.

[0010] Furthermore, the limiting mechanism includes a sliding plate, the outer surface of which is slidably connected to the support plate, and the inner wall of the sliding plate is provided with a plurality of locking holes, the inner wall of which is slidably connected to a pin.

[0011] Furthermore, the power mechanism includes a fixed plate, the outer surface of which is fixedly connected to a support plate. A motor fixed to the support platform is provided on one side of the fixed plate. A threaded rod is fixedly connected to the output end of the motor. The outer surface of the threaded rod is rotatably connected to the fixed plate, and the outer surface of the threaded rod is threadedly connected to a sliding plate.

[0012] Furthermore, a sliding rod is fixedly connected to one side of the sliding plate, and the outer surface of the sliding rod is slidably connected to the fixed plate.

[0013] (iii) Beneficial effects:

[0014] Compared with existing technologies, this SPMT modular detachable transport lifting beam has the following advantages:

[0015] I. This SPMT modular detachable transport lifting beam, through the setting of support plates and sliding mechanisms, allows operators to install or remove the sliding mechanism through the mounting port at the end of the support plate when facing complex working conditions with uneven load distribution. This allows for adjustment of the number of hydraulic lifting components, increasing the number in areas with heavy loads and decreasing the number in areas with light loads. Simultaneously, by pushing the sliding mechanism along the sliding groove, the horizontal position of the hydraulic lifting components can be precisely adjusted to ensure that they can evenly distribute the weight of the goods, avoiding deformation or damage to the support platform due to excessive local loads. This effectively solves the problems of insufficient load-bearing capacity and poor stability in traditional systems, especially in complex working conditions such as uneven load distribution during transportation, which can easily lead to beam deformation or even damage, affecting transportation safety.

[0016] II. This SPMT modular detachable transport lifting beam, through the inclusion of a power mechanism and other components, allows the power mechanism to reverse its operation when the hydraulic lifting assembly needs to be disassembled or adjusted. The motor drives the threaded rod to rotate in the opposite direction, causing the sliding plate to move away from the support plate. This separates the locking hole from the pin, releasing the limitation on the sliding mechanism. At this point, the operator can remove the sliding mechanism from the sliding groove through the mounting port, achieving rapid disassembly of the hydraulic lifting assembly. If only position adjustment is needed, the mounting plate can be directly pushed to slide. To fix it again, the above limitation steps can be repeated. This design not only enables flexible adjustment of the hydraulic lifting assembly but also achieves rapid installation and disassembly, significantly improving the adaptability of the equipment and construction efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The electric motor 702 in this utility model is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0026] like Figure 1-5 As shown, this utility model provides a technical solution: an SPMT combined detachable transport lifting beam, including a support platform 1. Multiple hydraulic lifting components 2 are arranged below the support platform 1 to support it. A connecting component is provided between the hydraulic lifting components 2 and the support platform 1. The connecting component includes a support plate 3, the upper surface of which is fixedly connected to the support platform 1. A sliding groove 4 is formed on the inner wall of the support plate 3, and a horizontally sliding mechanism 5 is provided on the inner wall of the sliding groove 4. The lower part of the sliding mechanism 5 is connected to the hydraulic lifting components 2. A limiting mechanism 6 is provided on the side of the support plate 3, and a power mechanism 7 is provided outside the limiting mechanism 6. Heavy goods are placed on top of the support platform 1 and supported by the hydraulic lifting components 2. The hydraulic lifting components 2 consist of support legs and connecting blocks that can move up and down. The connecting blocks are connected to the lower axle. The modules are connected, and hydraulic rods are installed between the support legs and the connecting blocks for lifting to adjust the height of the support legs. There are multiple support plates 3, equidistantly arranged on the lower surface of the support plates 3. During use, the position of the sliding mechanism 5 can be adjusted so that different numbers of sliding mechanisms 5 can be installed on different support plates 3. At the same time, they can slide on the support plates 3 to adjust their positions, thereby changing the number and position of the hydraulic lifting components 2. This allows for adjustment, enabling the installation of multiple hydraulic lifting components 2 in areas with high loads to avoid deformation and other problems caused by uneven loads. After the position of the sliding mechanism 5 is determined, the power mechanism 7 drives the limiting mechanism 6 to move closer to the support plate 3, thereby locking the sliding mechanism 5 for fixation. Similarly, during disassembly, the lower limiting mechanism 6 moves away from the support plate 3 to facilitate disassembly, achieving a quick installation and disassembly effect.

[0027] The sliding mechanism 5 includes a mounting plate 501, the outer surface of which is slidably connected to the support plate 3, and the lower surface of which is fixedly connected to the hydraulic lifting assembly 2. Pins 502 are fixedly connected to both sides of the mounting plate 501. The outer surface of the pins 502 is slidably connected to the sliding groove 4. The end of the support plate 3 is provided with a mounting opening 8. The sliding groove 4 is used to restrict the pins 502, so that the pins 502 can slide on the inner wall of the sliding groove 4 to adjust the position of the mounting plate 501. The width of the mounting opening 8 is greater than the width of the middle part of the support plate 3 so that the pins 502 can slide inward at the mounting opening 8.

[0028] The limiting mechanism 6 includes a sliding plate 601. The outer surface of the sliding plate 601 is slidably connected to the support plate 3. The inner wall of the sliding plate 601 is provided with multiple locking holes 602. The inner wall of the locking holes 602 is slidably connected to the pins 502. When the sliding plate 601 is close to the support plate 3, the pins 502 on the support plate 3 can be inserted into the locking holes 602. The support plate 3 fixes the mounting plate 501 vertically, and the sliding plate 601 fixes the mounting plate 501 horizontally, thereby completely fixing the mounting plate 501. The center of the mounting plate 501 is provided with a scribe line, and the sliding plate 601 is also provided with scribe lines that match the number of locking holes 602 to facilitate its installation.

[0029] The power mechanism 7 includes a fixed plate 701, the outer surface of which is fixedly connected to the support plate 3. A motor 702 is fixed to the support platform 1 on one side of the fixed plate 701. A threaded rod 703 is fixedly connected to the output end of the motor 702. The outer surface of the threaded rod 703 is rotatably connected to the fixed plate 701. The outer surface of the threaded rod 703 is threadedly connected to the sliding plate 601. The motor 702 can drive the threaded rod 703 to rotate. The threaded rod 703 is a bidirectional thread, with two threads of opposite directions on both sides of the middle side. When the threaded rod 703 rotates, it can drive the two sliding plates 601 to move closer or further apart, so as to facilitate the fixing and disassembly of the mounting plate 501.

[0030] A sliding rod 704 is fixedly connected to one side of the sliding plate 601. The outer surface of the sliding rod 704 is slidably connected to the fixed plate 701. The sliding rod 704 is used to increase the stability of the sliding plate 601 and prevent it from tilting and falling.

[0031] Working principle: The area above the support platform 1 serves as a placement area for heavy goods such as large precast bridge beams. The weight of the goods is transferred through the support platform 1 to multiple hydraulic lifting components 2 below. The support legs in the hydraulic lifting components 2 are connected to the axle module below through connecting blocks to form a basic support structure. The hydraulic rods between the support legs and the connecting blocks can be extended and retracted to adjust the height of the support legs, thereby adapting to different load-bearing requirements and terrain conditions, and ensuring the level and stability of the support platform 1.

[0032] Since the support plates 3 are evenly distributed on the lower surface of the support platform 1, and each support plate 3 has a sliding groove 4 with a horizontally sliding mechanism 5, the lower surface of the mounting plate 501 of the sliding mechanism 5 is fixedly connected to the hydraulic lifting assembly 2, and the pins 502 on both sides can slide along the sliding groove 4, when facing complex working conditions with uneven load distribution, the operator can install or remove the sliding mechanism 5 through the mounting port 8 at the end of the support plate 3, thereby adjusting the number of hydraulic lifting assemblies 2. The number of hydraulic lifting assemblies 2 can be increased in areas with larger loads and decreased in areas with smaller loads. At the same time, by pushing the mounting plate 501 to make the pins 502 slide along the sliding groove 4, the horizontal position of the hydraulic lifting assembly 2 can be precisely adjusted to ensure that it can evenly distribute the weight of the goods and avoid deformation or damage to the support platform 1 due to excessive local load.

[0033] After the position and quantity of the hydraulic lifting assembly 2 are adjusted, the power mechanism 7 starts to work. The motor 702 drives the threaded rod 703 to rotate. Since the threaded rod 703 is a bidirectional thread, the threads on both sides with opposite directions of rotation will drive the two sliding plates 601 to move along the sliding rod 704 towards the support plate 3. As the sliding plates 601 move, the locking holes 602 on their inner walls gradually engage with the pins 502 on both sides of the mounting plate 501. Combined with the upper and lower limiting effect of the support plate 3 on the mounting plate 501, the sliding mechanism 5 is completely fixed, thereby locking the position of the hydraulic lifting assembly 2 and ensuring that no displacement occurs during transportation.

[0034] When the hydraulic jacking assembly 2 needs to be disassembled or adjusted, the power mechanism 7 reverses its operation, and the motor 702 drives the threaded rod 703 to rotate in the opposite direction, causing the sliding plate 601 to move away from the support plate 3. The locking hole 602 separates from the pin 502, releasing the restriction on the sliding mechanism 5. At this time, the operator can remove the sliding mechanism 5 from the sliding groove 4 through the mounting port 8, realizing the quick disassembly of the hydraulic jacking assembly 2. If only the position needs to be adjusted, the mounting plate 501 can be directly pushed to slide. When fixing it again, the above restriction steps can be repeated. This design not only realizes the flexible adjustment of the hydraulic jacking assembly 2, but also achieves the effect of quick installation and disassembly, greatly improving the adaptability of the equipment and the construction efficiency.

[0035] Through the above working process, this modular detachable transport beam can flexibly adjust the support structure according to the load distribution characteristics of the goods, effectively solving the problems of insufficient load-bearing capacity and poor stability caused by the fixed leg layout of traditional transport beams, and ensuring the safety and reliability of transporting ultra-large and heavy goods.
