Abstract

This application belongs to the field of steel transportation technology and discloses a steel transportation fixing device, including several crossbeams arranged at intervals. Vertical pipes are installed at both ends of the crossbeams, and through holes are vertically opened on the pipe walls of the vertical pipes perpendicular to the crossbeams. A clamping beam assembly is slidably installed in the through holes of both ends of the vertical pipes. Sliding blocks and a lifting assembly that drives the sliding blocks to move vertically are installed on the outside of the vertical pipes. In use, the two ends of the clamping beam assembly protrude from the vertical pipes. A driving assembly is installed inside the crossbeams. The driving assembly drives the lifting assemblies at both ends to move synchronously, causing the sliding blocks to move downwards and press down on both ends of the clamping beam assembly, thus clamping the steel in the carriage.

Description

Technical Field

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

[0002] The transportation of construction steel is a high-frequency and critical business segment in the daily operations of commercial and logistics companies. Its transportation efficiency and safety directly affect the company's economic benefits and market competitiveness. To ensure the safety of construction steel during transportation, it is usually necessary to effectively secure the steel.

[0003] Currently, during the transportation of long steel bars, most drivers typically use simple tools such as ropes and chains to bind them. During transportation, especially when encountering bumpy road conditions, sudden braking, or acceleration, the binding points are prone to loosening, causing the steel bars to shift or slip. This can not only damage the steel bars themselves but also pose serious safety hazards to the transport vehicle and the surrounding environment. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a steel transport and fixing device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel transport fixing device, comprising several crossbeams spaced apart along the length of the vehicle on the floor of the carriage, with vertical pipes at both ends of the crossbeams, and through holes vertically opened on the pipe walls of the vertical pipes perpendicular to the crossbeams. A pressing beam assembly is slidably arranged in the through holes of the two vertical pipes. A sliding block and a lifting assembly for driving the sliding block to move vertically are arranged on the outside of the vertical pipe. In the use state, the two ends of the pressing beam assembly protrude from the vertical pipe. The lifting assembly drives the sliding block to move downward and press down on the two ends of the pressing beam assembly so that the pressing beam assembly presses the steel in the carriage. A driving assembly for driving the lifting assemblies at both ends to move synchronously is arranged inside the crossbeam.

[0006] By adopting the above technical solution, a crossbeam, uprights, clamping beam assembly, sliding blocks, lifting assembly, and drive assembly are set up. The frame structure of the crossbeam and uprights provides a stable support foundation for the steel, adapting to the layout of the carriage floor. The drive assembly drives the lifting assemblies at both ends to move synchronously, causing the sliding blocks at both ends to press down synchronously on both ends of the clamping beam assembly. This causes the clamping beam assembly to move downward and press down on the steel in the carriage. The synchronous pressing down at both ends ensures that the steel is subjected to uniform force, avoiding the steel from shifting or overturning due to unilateral clamping. Compared with traditional manual binding, it can effectively ensure continuous clamping force on the steel and improve transportation safety.

[0007] Furthermore, the clamping beam assembly includes clamping beams respectively disposed in the cavities of two risers. The clamping beams are square tubes with a width smaller than the width of the through hole and a height smaller than the height of the through hole. Trunnions are provided on the opposite two sides of the tube wall at one end of the clamping beam. The axis of the trunnion is aligned with the width direction of the through hole. Rollers with a diameter consistent with the width of the riser cavity are rotatably disposed on the trunnion. The rollers are rolled within the riser cavity. A connecting beam is slidably disposed in the cavity at the end of one clamping beam away from the trunnion. When the two clamping beams are horizontally collinear, one end of the connecting beam slides into the other clamping beam.

[0008] By adopting the above technical solution, the clamping beam assembly is split into two clamping beams and connected in a detachable manner by a connecting beam. This allows the clamping beam assembly to be opened and placed in the riser cavities at both ends, which facilitates the hoisting of steel and the storage of the clamping beams when unloaded.

[0009] Furthermore, the pressure beam has two connecting holes spaced apart along its length at the end away from the trunnion, and a strip-shaped hole is provided on the connecting beam along its length. The connecting holes and the strip-shaped hole are connected by bolts.

[0010] By adopting the above technical solution, connecting holes and strip holes are set and connected by bolts, which facilitates the movement of the connecting beam between the two pressure beams to achieve disassembly and assembly; the design of two connecting holes can enhance the strength of the connection point, so that the two pressure beams form a stable whole, prevent the connection from loosening due to transportation vibration, and improve the structural reliability.

[0011] Furthermore, a groove is provided on the pipe wall on the side of the pressure beam that contacts the steel, and a rubber pad is fixedly installed in the groove.

[0012] By adopting the above technical solution, a rubber pad is set on the side of the pressure beam that contacts the steel, so that the pressure beam provides a buffer when pressing the steel, which can reduce damage to the surface of the steel; at the same time, it increases the friction between the pressure beam and the steel, preventing the steel from sliding during transportation.

[0013] Furthermore, the lifting assembly includes fixed plates at the upper and lower ends of the riser, a lead screw is rotatably arranged between the two fixed plates, the sliding block is provided with a threaded hole and forms a helical engagement with the lead screw through the threaded hole, the lower end of the lead screw penetrates the fixed plate and the wall of the crossbeam and extends into the crossbeam cavity, and the end of the pressure beam near the trunnion protrudes from the riser and has a notch to avoid the lead screw.

[0014] By adopting the above technical solution, a lead screw is set and screwed into the sliding block, providing stable lifting power for the sliding block; the notch design avoids interference between the pressure beam and the lead screw, ensuring normal operation of the device.

[0015] Furthermore, the drive assembly includes a rotating rod rotatably disposed within the crossbeam, with worm gears at both ends of the rotating rod and a worm wheel at the lower end of the lead screw. The worm gears cooperate with the worm wheel. Baffles are provided at both ends of the crossbeam, and rotating shafts are rotatably disposed on the baffles. The end of the worm gear away from the rotating rod is connected to the rotating shaft, and a hexagonal countersunk hole is provided at the outer end of one of the rotating shafts.

[0016] By adopting the above technical solution, a worm gear drives the lead screw to rotate. The self-locking function of the worm gear transmission can ensure the stability of the clamping force during vehicle operation. A hexagonal countersunk hole is provided to facilitate the use of tools to drive the worm and rotating shaft to rotate, making operation simple.

[0017] Furthermore, several mounting plates are arranged at intervals inside the crossbeam, and the rotating rod is rotatably mounted on several mounting plates.

[0018] By adopting the above technical solution, the mounting plate provides stable support for the rotating rod, reduces shaking and noise during rotation, and ensures synchronous movement of the worm gears at both ends.

[0019] In summary, this utility model has the following beneficial effects: In this application, by setting up a crossbeam, a vertical pipe, a clamping beam assembly, sliding blocks, a lifting assembly, and a driving assembly, the frame structure of the crossbeam and the vertical pipe provides a stable support foundation for the steel, adapting to the layout of the carriage floor; the driving assembly drives the lifting assemblies at both ends to move synchronously, causing the sliding blocks at both ends to press down synchronously on both ends of the clamping beam assembly, so that the clamping beam assembly moves downward and clamps the steel in the carriage. The synchronous pressing down at both ends can ensure that the steel is subjected to uniform force, avoiding the steel from shifting or overturning due to unilateral clamping. Compared with traditional manual binding, it can effectively ensure continuous clamping force on the steel and improve transportation safety. Attached Figure Description

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-4 As shown in the illustration, this application discloses a steel transport fixing device, including several crossbeams 10 spaced apart along the length of the vehicle on the floor of the cargo box. Upright pipes 20 are installed at both ends of each crossbeam 10, forming a frame structure that adapts to the layout of the cargo box floor and provides a stable supporting foundation for the steel. The number of crossbeams 10 is determined according to the length of the cargo box, with at least two beams provided to accommodate the needs of different types of trucks, demonstrating strong versatility.

[0027] A through hole 21 is vertically formed on the wall of the riser 20 perpendicular to the crossbeam 10. A clamping beam assembly 30 is slidably disposed within the through holes 21 of both ends of the riser 20. Specifically, the clamping beam assembly 30 includes clamping beams 31 respectively disposed within the cavities of the two risers 20. The clamping beams 31 are square tubular structures, with a width smaller than the width of the through hole 21 and a height smaller than the height of the through hole 21, allowing the clamping beams 31 to be placed within the cavities of the risers 20 and removed from the through holes 21. Trunnions 32 are disposed on the opposite sides of one end of the clamping beams 31. The axis of the trunnions 32 is aligned with the width direction of the through hole 21. Rollers 33 with a diameter matching the width of the cavities of the risers 20 are rotatably disposed on the trunnions 32, causing the rollers 33 to roll within the cavities of the risers 20. This allows the clamping beams 31 to slide up and down within the cavities of the risers 20 via the rollers 33.

[0028] A connecting beam 70 is slidably disposed within the cavity of one of the pressure beams 31 at the end away from the trunnion 32. The connecting beam 70 is a square beam, and its cross-sectional profile matches the cavity profile of the pressure beam 31. When the two pressure beams 31 are horizontally collinear, one end of the connecting beam 70 slides into the other pressure beam 31, thus connecting the two pressure beams 31 into a whole. During installation, two connecting holes 34 are spaced apart along the length of the pressure beam 31 at the end away from the trunnion 32. A strip-shaped hole 71 is provided on the connecting beam 70 along its length, and the connecting hole 34 and the strip-shaped hole 71 are connected by bolts 80. The connecting hole 34 is an oblong hole, which facilitates the insertion of the bolts 80 during connection. In the non-working state, the connecting beam 70 is inserted into one of the pressure beams 31, and then fixed with two bolts 80 passing through the connecting hole 34 and the strip-shaped hole 71. The connecting beam 70 can slide relative to the bolts 80 through the strip-shaped hole 71, thus allowing the connecting beam 70 to be housed within the cavity of the pressure beam 31. In operation, the two pressure beams 31 are pulled out from the riser 20 and placed horizontally. Then, the connecting beam 70 is pulled so that one end slides into the other pressure beam 31. Bolts 80 are then passed through the connecting hole 34 and the slotted hole 71 for fixation. The bolts 80 and the connecting beam 70 together form a stable whole. The four bolts 80 effectively enhance the connection strength, preventing misalignment of the two pressure beams 31 during the pressing process. This allows for a detachable connection of the pressure beam assembly 30, facilitating the hoisting of steel and the storage of the pressure beams 31 when unloaded. To ensure stable storage of the pressure beams 31 when unloaded, the bottom edge of the through hole 21 is designed to be higher than the crossbeam 10 by a certain height. This allows the lower end of the pressure beam 31 to be placed inside the cavity of the riser 20 below the through hole 21. The four side walls of the riser 20 limit the pressure beam 31, effectively preventing it from slipping out during unloaded vehicle operation.

[0029] A further feature is that a groove is formed on the pipe wall on the side of the pressure beam 31 that contacts the steel, and a rubber pad 35 is fixedly installed in the groove. The rubber pad 35 provides cushioning when the pressure beam 31 presses the steel, which can reduce damage to the surface of the steel; at the same time, it increases the friction between the pressure beam 31 and the steel, preventing the steel from sliding during transportation.

[0030] A sliding block 40 and a lifting assembly 50 for driving the sliding block 40 to move vertically are also provided on the outside of the riser 20. The lifting assembly 50 is used to drive the sliding block 40 to move downward and press down on both ends of the clamping beam assembly 30 so that the clamping beam assembly 30 presses down on the steel in the carriage. Specifically, the lifting assembly 50 includes fixed plates 51 set at the upper and lower ends of the riser 20. The upper and lower fixed plates 51 have concentric holes, and bearings are set in the holes. A lead screw 52 is rotatably set between the upper and lower fixed plates 51 through the upper and lower bearings. The sliding block 40 has a threaded hole and forms a helical engagement with the lead screw 52 through the threaded hole. One side of the sliding block 40 is arranged close to the riser 20 so that when the lead screw 52 rotates, the sliding block 40 is limited and cannot rotate, so it can only move up and down along the lead screw 52. The end of the pressure beam 31 near the trunnion 32 protrudes from the riser 20 and has a notch 36 to avoid the lead screw 52. In use, first rotate the sliding block 40 to a height higher than the stacked steel. After the two pressure beams 31 are connected by the connecting beam 70, rotate the screw 52 to make the sliding block 40 move downward and contact the outer end of the pressure beam 31 and continue to press down, thereby driving the pressure beam 31 to press down on the steel and tighten it.

[0031] To ensure that the sliding blocks 40 at both ends of the crossbeam 10 can rise and fall synchronously, the lower end of the lead screw 52 passes through the fixed plate 51 and the tube wall of the crossbeam 10 and extends into the cavity of the crossbeam 10. A drive assembly 60 is installed inside the crossbeam 10 to drive the lead screw 52 of the lifting assemblies 50 at both ends to move synchronously. The drive assembly 60 includes a rotating rod 61 rotatably disposed within the crossbeam 10, with worm gears 62 at both ends of the rotating rod 61 and a worm wheel 63 at the lower end of the lead screw 52. The worm gears 62 and worm wheel 63 cooperate, so that only the rotation of the worm gears 62 is needed to drive the worm wheel 63 to rotate, thereby driving the lead screws 52 at both ends to rotate synchronously. The worm gear 62 and worm wheel 63 transmission has good self-locking capability, ensuring that the lead screw 52 will not rotate during vehicle operation, thus ensuring the stability of the clamping force. In the specific configuration, baffles 64 are installed at both ends of the crossbeam 10. Through holes are formed in the baffles 64, and bearings are installed within these holes. A rotating shaft 65 is rotatably mounted on the baffles 64 via the bearings. The end of the worm gear 62 furthest from the rotating rod 61 is connected to the rotating shaft 65. Thus, the rotating shafts 65 at both ends, the worm gear 62, and the rotating rod 61 in the middle are connected as a single unit. Rotation of any one component can drive the worm gears 62 at both ends to rotate synchronously. A hexagonal countersunk hole 66 is formed at the outer end of one of the rotating shafts 65. By inserting an L-shaped wrench or other tool into the hexagonal countersunk hole 66, the rotating shaft 65 can be driven to rotate, thereby driving the worm gears 62 at both ends to rotate synchronously.

[0032] To ensure the stability of the synchronous rotation of the worm gears 62 at both ends, several mounting plates 67 are arranged at intervals within the crossbeam 10, and the rotating rod 61 is rotatably mounted on these mounting plates 67. Each mounting plate 67 has a through hole, within which a bearing is installed, and the rotating rod 61 is mounted within the bearing. The mounting plates 67 provide stable support for the rotating rod 61, reducing swaying and noise during rotation and ensuring synchronous movement of the worm gears 62 at both ends.

[0033] The working principle of the steel transport fixing device in this embodiment is as follows: First, the steel is stacked on the crossbeam 10. A tool is inserted into the hexagonal countersunk hole 66 to rotate the rotating shaft 65. The worm gear 62 and worm wheel 63 drive the lead screw 52 to rotate, causing the sliding block 40 to move to a height higher than the stacked steel. Then, the pressure beam 31 is pulled up from the cavity of the riser 20 and pulled out from the through hole 21. The pressure beam 31 is then slid to the height of the top surface of the steel and placed on the steel. Then, the connecting beam 70 is pulled out from one of the pressure beams 31 and inserted into the other pressure beam 31. Then, the bolt 80 is passed through the connecting hole 34 and fixed to the strip hole 71. Next, the rotating shaft 65 is rotated using a tool. The worm gear 62 and worm wheel 63 drive the lead screw 52 to rotate, causing the sliding block 40 to move downward and press down on the end of the pressure beam 31. By pressing down from both ends simultaneously, the entire pressing beam assembly 30 presses down on the steel, compressing the steel and improving safety during transportation.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
