Description

Technical Field

[0001] This application relates to the field of steel section transportation technology, and in particular to a transport vehicle for hot-pressed steel sections. Background Technology

[0002] In modern industrial production, hot-pressed steel profiles are an important structural material and are widely used in many fields such as construction and machinery manufacturing. The production process of hot-pressed steel profiles involves multiple steps, from forming to subsequent processing. Frequent transfers are required between each step. In order to improve the transfer efficiency of steel profiles, workers usually use transport vehicles to transport bundles of steel profiles.

[0003] However, in industrial workshop environments, a large amount of scrap material is generated during the production process, and the workshop floor is often littered with scrap iron blocks and other debris. When transport vehicles drive on workshop floors covered with debris, the vehicles are likely to experience bumps. At this time, the bundled steel sections will have relative displacement with the transport vehicle body, which can easily cause the bundled steel sections to fall off the transport vehicle, thereby interrupting the steel section transfer process and reducing the efficiency of steel section transfer, which is obviously insufficient. Utility Model Content

[0004] In order to reduce the possibility of steel sections falling off the transport vehicle and improve the transfer efficiency of steel sections, this application provides a transport vehicle for hot-pressed steel sections.

[0005] The technical solution for a hot-pressed steel transport vehicle provided in this application is as follows:

[0006] A transport vehicle for hot-pressed steel profiles includes a support frame for carrying the steel profiles. Multiple rollers are provided on the outer surface of the support frame. A binding rope is provided on the support frame in an arc shape on the surface of the support frame. Guide cylinders are respectively provided on opposite sides of the support frame along its width direction. The opposite ends of the binding rope pass through the guide cylinders and extend to the bottom surface of the support frame. A tensioning component is provided on the support frame to control the tension of the binding rope. When the tensioning component tightens the binding rope, the binding rope wraps around the steel profile.

[0007] By adopting the above technical solution, when transporting hot-pressed steel sections, bundled steel sections are placed in a carrying frame. Then, workers use tensioning components to tighten the binding ropes, so that the arc-shaped binding ropes wrap around the steel sections. During the movement of the transport vehicle, the binding ropes restrain the steel sections within the carrying frame, thereby reducing the possibility of relative displacement between the steel sections and the carrying frame, causing them to fall off the transport vehicle, and improving the transfer efficiency of the steel sections.

[0008] Optionally, the tensioning assembly includes a mounting plate disposed on the bottom surface of the support frame. A movable block corresponding to each end of the binding rope is slidably connected to the mounting plate. The end of the binding rope is disposed on the corresponding movable block. A gear is rotatably connected to the mounting plate. A rack plate corresponding to each of the two movable blocks is meshed on the gear. The two rack plates are respectively disposed on both sides of the gear. The movable blocks are disposed on the corresponding rack plates. A drive assembly for driving the gear to rotate is disposed on the support frame.

[0009] By adopting the above technical solution, after the steel section is placed inside the bearing frame, the drive component drives the gear to rotate in the forward direction. The gear drives the two rack plates to move towards each other. The rack plates pull the two ends of the binding rope closer and closer through the moving block. At this time, the binding rope tightens and constrains the steel section.

[0010] When the steel section needs to be unloaded, the drive assembly drives the gear to rotate in the opposite direction. The gear drives the two moving blocks away from each other through the rack plate. The distance between the ends of the binding rope increases continuously, and the binding rope loosens and detaches from the steel section. This makes it easier for workers to unload the steel section. The drive assembly enables automatic adjustment of the binding rope tension, effectively reducing the occurrence of problems such as the steel section falling off due to the binding rope being too loose, or the steel section surface being damaged due to the binding rope being too tight.

[0011] Optionally, multiple binding ropes are provided, and the multiple binding ropes are evenly and equidistantly arranged along the length direction of the support frame.

[0012] By adopting the above technical solution, multiple evenly spaced binding ropes can constrain and fix the bundled steel sections from multiple points, greatly enhancing the fixing effect compared to a single binding rope. At the same time, it makes the constraint force on the steel sections more evenly distributed, ensuring stability within the frame and effectively reducing the risk of the steel sections falling off the transport vehicle.

[0013] Optionally, the drive assembly includes a motor disposed at the end of the support frame, the output shaft of the motor being coaxially provided with a linkage shaft, the linkage shaft passing through the mounting plate in sequence, and a plurality of gears being fixedly sleeved on the outer surface of the linkage shaft.

[0014] By adopting the above technical solution, the motor starts and drives the linkage shaft to rotate, which in turn drives multiple gears to rotate synchronously, thereby achieving the synchronous loosening or tightening of multiple binding ropes. The setting of the drive component avoids the tedious operation of workers manually adjusting the binding ropes one by one, further improving the efficiency of steel loading and unloading.

[0015] Optionally, the mounting plate is provided with guide posts corresponding to the two movable blocks one by one, and the movable blocks slide through the corresponding guide posts.

[0016] By adopting the above technical solution, when the tensioning component drives the moving block to move through the gear and rack transmission, the moving block slides stably on the guide column, reducing the phenomenon of deviation or jamming during the movement, thereby ensuring that the two ends of the binding rope can be tightened or loosened smoothly in the predetermined direction, and ensuring the smooth progress of the steel loading and unloading process.

[0017] Optionally, a blocking plate is fixedly provided at one end of the bearing frame along its length, and a rotating shaft is rotatably connected to the other end. A surrounding plate is fixedly provided on the rotating shaft, and a linkage component is provided on the bearing plate. The driving component drives the surrounding plate to rotate through the linkage component.

[0018] By adopting the above technical solution, during the process of the drive component driving the tensioning component to tighten the binding rope, the drive component drives the tail plate to rotate to a vertical position through the linkage component. At this time, the enclosure plate and the blocking plate cooperate to limit the two ends of the binding rope, reducing the possibility of the steel section separating from both ends of the load-bearing frame in the length direction, thereby further improving the transportation efficiency of the steel section.

[0019] Optionally, the linkage component includes a worm gear coaxially arranged with the linkage shaft, and a worm wheel coaxially arranged on the rotating shaft to mesh with the worm gear. When the drive component drives the two moving blocks to move closer to each other, the enclosure rotates toward the support frame.

[0020] By adopting the above technical solution, when the drive component drives the linkage shaft to rotate in the forward direction, the drive component drives the rotating shaft to rotate through the transmission action of the worm and worm wheel. The rotating shaft drives the enclosure to rotate to the vertical position. When the drive component drives the linkage shaft to rotate in the reverse direction, the worm drives the enclosure to rotate to the horizontal position through the worm wheel. This makes it easier for workers to unload the steel profiles. The linkage component eliminates the need for workers to operate the enclosure and the binding ropes separately. They only need to start the drive component to simultaneously complete the actions of tightening the binding ropes to fix the steel profiles and raising the enclosure to close both ends of the load-bearing frame, further improving the efficiency of steel profile loading and unloading.

[0021] Optionally, the surface of the support frame is provided with a receiving groove, and multiple conveying rollers are rotatably connected in the receiving groove. The multiple conveying rollers are evenly and equidistantly arranged along the length direction of the receiving groove.

[0022] By adopting the above technical solution, during the loading or unloading of steel sections, the rolling characteristics of the conveyor rollers reduce the friction between the steel sections and the support frame, allowing workers to move the steel sections more easily, reducing manpower consumption and operation time, and further improving the efficiency of steel section loading and unloading.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this embodiment of the application, by setting up a drive assembly, a tensioning assembly, and multiple binding ropes, when transporting hot-pressed steel sections, the bundled steel sections are placed in a carrying frame. Then, the workers use the tensioning assembly to tighten the binding ropes, so that the arc-shaped binding ropes wrap around the steel sections. During the movement of the transport vehicle, the binding ropes constrain the steel sections within the carrying frame, thereby reducing the possibility of relative displacement between the steel sections and the carrying frame, causing them to fall off the transport vehicle, and improving the transfer efficiency of the steel sections.

[0025] 2. In this embodiment of the application, by setting up a surrounding plate and a linkage component, during the process of the driving component driving the tensioning component to tighten the binding rope, the driving component drives the tail plate to rotate to a vertical position through the linkage component. At this time, the surrounding plate and the blocking plate cooperate to limit the two ends of the binding rope, reducing the possibility of the steel section separating from both ends of the bearing frame in the length direction, thereby further improving the transportation efficiency of the steel section.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a transport vehicle for hot-pressed steel profiles.

[0032] Reference Figure 1 A transport vehicle for hot-pressed steel includes a support frame 1 for carrying the steel, and a plurality of rollers 101 are mounted on the outer surface of the bottom end of the support frame 1. The rollers 101 slide inside the guide rails of the workshop.

[0033] Reference Figure 1The surface of the support frame 1 is provided with a receiving groove 102. Multiple conveying rollers 103 are rotatably connected inside the receiving groove 102. The top cut surface of the conveying rollers 103 is flush with the upper surface of the support frame 1. The multiple conveying rollers 103 are evenly and equidistantly arranged along the length of the receiving groove 102. During the process of loading or unloading the steel, the rolling characteristics of the conveying rollers 103 reduce the friction between the steel and the support frame 1, making it easier for workers to move the steel.

[0034] Reference Figure 1 and Figure 2 Multiple binding ropes 2 are provided on the support frame 1. The multiple binding ropes 2 are evenly distributed at equal intervals along the length direction of the support frame 1. The binding ropes 2 are arranged in an arc shape on the surface of the support frame 1. Guide cylinders 3 corresponding to the multiple binding ropes 2 are fixedly connected to both sides of the support frame 1 along the width direction. Both ends of each binding rope 2 pass through the corresponding guide cylinder 3 and extend to the bottom surface of the support frame 1. The support frame 1 is provided with a drive assembly 4 and multiple tensioning assemblies 5. The multiple tensioning assemblies 5 are arranged in a one-to-one correspondence with the multiple binding ropes 2. When the drive assembly 4 drives the multiple tensioning assemblies 5 to simultaneously tighten the corresponding binding ropes 2, the multiple binding ropes 2 simultaneously wrap the steel section.

[0035] Reference Figure 1 and Figure 2 The tensioning assembly 5 includes a mounting plate 51 fixedly installed on the bottom surface of the support frame 1. Multiple mounting plates 51 are evenly distributed at equal intervals along the length direction of the support frame 1. Moving blocks 52 corresponding to the two ends of the binding rope 2 are slidably connected on the mounting plate 51. The end of the binding rope 2 passing through the guide tube 3 is fixedly connected to the corresponding moving block 52.

[0036] Reference Figure 1 and Figure 2 A gear 53 is rotatably connected to the center of the mounting plate 51. A rack plate 54 corresponding to each of the two moving blocks 52 is meshed on the gear 53. The rack plate 54 is slidably connected to the surface of the mounting plate 51 by means of a slider and a groove. The two rack plates 54 are respectively set on the upper and lower sides of the gear 53. Each moving block 52 is fixedly connected to the corresponding rack plate 54. A guide post 511 corresponding to each of the two moving blocks 52 is fixedly connected to the mounting plate 51. The moving block 52 slides through the corresponding guide post 511.

[0037] Reference Figure 2 and Figure 3 The drive assembly 4 includes a motor 41 fixedly mounted on one end of the support frame 1. The output shaft of the motor 41 is coaxially and fixedly connected to a linkage shaft 42. The linkage shaft 42 is parallel to the length direction of the support frame 1. The linkage shaft 42 passes through multiple mounting plates 51 in sequence. Multiple gears 53 are fixedly sleeved on the outer surface of the linkage shaft 42. In this embodiment, the motor 41 is a brake motor 41.

[0038] When transporting hot-pressed steel sections, workers place bundles of steel sections between the carrying frame 1 and multiple binding ropes 2. Then, the workers start the motor 41. The motor 41 drives multiple gears 53 to rotate synchronously in the forward direction through the linkage shaft 42. The gears 53 drive two meshing rack plates 54 to move towards each other. The movement of the rack plates 54 causes the distance between the two moving blocks 52 to continuously decrease. At this time, the moving blocks 52 pull the two ends of the binding ropes 2 closer to each other. The portions of the multiple binding ropes 2 located on the upper surface of the carrying plate continuously approach the steel section and eventually synchronously wrap the steel section, thereby forming an effective constraint on the steel section and reducing the possibility of the steel section falling off the transport vehicle due to relative displacement between the steel section and the carrying frame 1 during transportation, thus improving the transfer efficiency of the steel section.

[0039] Once the steel profile is transported to the designated location, the worker starts the motor 41. The motor 41 drives multiple gears 53 to rotate synchronously in opposite directions via the linkage shaft 42. At this time, the gears 53 drive two moving blocks 52 away from each other via the rack plate 54. The moving blocks 52 cause the distance between the two ends of the binding rope 2 to increase continuously. The multiple binding ropes 2 gradually loosen and detach from the surface of the steel profile. At this time, the binding force of the binding rope 2 on the steel profile disappears, making it easier for the worker to unload the steel profile. The setting of the drive component 4 and the tensioning component 5 realizes the automatic adjustment of the tension of the binding rope 2, effectively reducing the occurrence of problems such as the steel profile falling off due to the binding rope 2 being too loose, or the steel profile surface being damaged due to the binding rope 2 being too tight.

[0040] Reference Figure 2 and Figure 3 A baffle plate 6 is fixedly installed at the end of the support frame 1 near the motor 41, and a rotating shaft 7 is connected to the other end. The baffle plate 6 is integrally formed with the support frame 1. A surrounding plate 71 is fixedly installed on the rotating shaft 7. A linkage component 8 is provided on the support plate. The drive component 4 drives the surrounding plate 71 to rotate in the direction of approaching or moving away from the support frame 1 through the linkage component 8.

[0041] Reference Figure 2 and Figure 3 The linkage component 8 includes a worm 81 fixedly connected to the end of the linkage shaft 42 away from the motor 41. The worm 81 is coaxially arranged with the linkage shaft 42. A worm wheel 82 that meshes with the worm 81 is coaxially fixedly connected to the rotating shaft 7. The worm wheel 82 is located at the center of the rotating shaft 7. When the drive component 4 drives the two moving blocks 52 to approach each other, the enclosure 71 rotates toward the bearing frame 1.

[0042] When the drive assembly 4 drives the linkage shaft 42 to rotate in the forward direction, the drive shaft tightens the binding rope 2 on the outer surface of the steel section through the tensioning assembly 5. At the same time, the drive assembly 4 drives the rotating shaft 7 to rotate through the transmission action of the worm 81 and worm wheel 82. The rotating shaft 7 drives the enclosure plate 71 to rotate towards the direction close to the bearing frame 1 and finally abuts against the end face of the bearing frame 1. At this time, the enclosure plate 71 is in a vertical state and cooperates with the blocking plate 6 to limit the two ends of the binding rope 2, reducing the possibility of the steel section separating from the two ends of the bearing frame 1 in the length direction, thereby further improving the transportation efficiency of the steel section.

[0043] When the drive assembly 4 relaxes the binding rope 2 through the tensioning assembly 5, the drive assembly 4 drives the enclosure 71 to rotate away from the load-bearing frame 1 through the linkage assembly 8. At this time, the enclosure 71 is horizontal, which makes it convenient for workers to unload the steel.

[0044] The implementation principle of a hot-pressed steel section transport vehicle according to an embodiment of this application is as follows: When transporting hot-pressed steel sections, workers place bundles of steel sections between a bearing frame 1 and multiple binding ropes 2. Then, the workers start a motor 41. The motor 41 drives multiple gears 53 to rotate synchronously in the forward direction through a linkage shaft 42. The gears 53 drive two meshing rack plates 54 to move towards each other. The movement of the rack plates 54 causes the distance between the two moving blocks 52 to continuously decrease. At this time, the moving blocks 52 pull the two ends of the binding ropes 2 closer to each other. The portions of the multiple binding ropes 2 located on the upper surface of the bearing plate continuously approach the steel section and eventually synchronously wrap the steel section, thereby forming an effective constraint on the steel section and reducing the possibility of the steel section falling off the transport vehicle due to relative displacement between the steel section and the bearing frame 1 during transportation, thereby improving the transfer efficiency of the steel section.

[0045] Once the steel profile is transported to the designated location, the worker starts the motor 41. The motor 41 drives multiple gears 53 to rotate synchronously in opposite directions via the linkage shaft 42. At this time, the gears 53 drive two moving blocks 52 away from each other via the rack plate 54. The moving blocks 52 cause the distance between the two ends of the binding rope 2 to increase continuously. The multiple binding ropes 2 gradually loosen and detach from the surface of the steel profile. At this time, the binding force of the binding ropes 2 on the steel profile disappears, making it easier for the worker to unload the steel profile.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
