Description

Technical Field

[0001] This utility model relates to the field of building material transportation technology, and in particular to a protective device for building material transportation. Background Technology

[0002] Building materials are a general term for materials used in civil engineering and construction projects, including steel, stone, timber, cement, and plastics. Steel is an essential material for national construction, with wide applications and numerous varieties. Based on different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes, and metal products. It is further divided into heavy rails, light rails, large steel profiles, medium steel profiles, small steel profiles, cold-formed steel profiles, high-quality steel profiles, wire rods, medium and heavy steel plates, thin steel plates, electrical silicon steel sheets, strip steel, seamless steel pipes, welded steel pipes, and metal products. Transport vehicles are required to transport steel to construction sites for use.

[0003] Currently, steel coils are typically transported using ordinary flatbed trucks. Steel coils are hollow cylinders, and due to their large size and weight, they need to be placed horizontally on the truck bed for easy loading and unloading, with restraining blocks supporting their front and rear ends. During transport, if the vehicle is traveling at high speed and encounters a traffic accident or other sudden braking situation, the steel coil may move towards the driver's cab due to the vehicle's inertia, impacting the cab and potentially causing injury or even death to the driver. Bumps or the centripetal force during turns can also cause the steel coil to move sideways, potentially leading to it falling off and the vehicle overturning. Therefore, transporting steel coils is a highly dangerous task, necessitating a protective device to effectively safeguard them. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a protective device for transporting building materials.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective device for transporting building materials, comprising a floor plate fixedly installed on a carriage, two transverse sliding grooves being formed on the front and rear side plates of the floor plate along the length of the carriage, a positioning component being slidably disposed on the transverse sliding grooves, the positioning component including a positioning seat, the inner side of the positioning seat being a curved surface that mates with the steel coil, a triangular support seat being disposed on the outer side of the positioning seat, a driving component for driving the positioning seat to slide along the transverse sliding grooves being disposed at the front and rear ends of the floor plate, a vertical fixing hole being formed on the triangular support seat, and two rows of bolt holes being correspondingly formed on the floor plate along the length of the transverse sliding grooves, the positioning seat being fixed to the floor plate by bolts passing through the fixing holes and bolt holes after the driving component drives the positioning seat to slide into position; two longitudinal sliding grooves being formed on the left and right side plates of the floor plate along the width of the carriage, a limit component being slidably disposed on the longitudinal sliding grooves, the limit component limiting the two sides of the steel coil.

[0006] Furthermore, the positioning seat includes a vertically arranged positioning plate and a positioning block. The positioning plate has a T-shaped groove vertically formed on the side of the plate adjacent to the steel coil. The positioning block has a corresponding T-shaped protrusion on the side adjacent to the positioning plate. The T-shaped protrusion cooperates with the T-shaped groove. The side of the positioning block away from the positioning plate is a curved surface that cooperates with the steel coil. The bottom edge of the positioning plate is provided with a first slider corresponding to the transverse sliding groove. The bottom edge of the positioning block is provided with a second slider corresponding to the transverse sliding groove.

[0007] Furthermore, a fixing plate is provided on the side of the positioning plate away from the steel coil. A third slider is provided on the bottom edge of the fixing plate corresponding to the transverse sliding groove. The fixing plate and the positioning plate are connected by a number of springs arranged in an array. The triangular support base includes a horizontal plate, a vertical plate and a triangular support plate. The surface of the vertical plate is attached to and fixedly connected to the surface of the fixing plate. A vertical fixing hole is opened on the horizontal plate.

[0008] Furthermore, the drive assembly includes pads disposed at the front and rear ends of the base plate, and electric push rods are disposed on the pads. The push rod ends of the electric push rods are connected to the vertical plate of the triangular support base.

[0009] Furthermore, the limiting component includes a limiting seat, a longitudinal slider is provided at the bottom of the limiting seat corresponding to the longitudinal groove, and fixed seats are provided on the left and right sides of the base plate. The fixed seats have threaded holes, and a threaded rod is rotatably provided in the threaded holes. The limiting seat has a corresponding through hole, and a groove larger than the diameter of the through hole is provided at the inner end of the limiting seat. One end of the threaded rod near the limiting seat passes through the through hole and enters the groove, and a baffle is provided at the end. The other end of the threaded rod away from the limiting seat is located outside the fixed seat and a turntable is provided at the end. A rotating shaft is provided on the turntable.

[0010] Furthermore, a locking nut is provided on the rod body of the threaded rod located between the limiting seat and the fixed seat.

[0011] Furthermore, the limiting seat has a vertical notch in the middle, a screw is vertically arranged in the notch, a limiting rod is vertically slidably arranged on the screw, and a fixing nut is spirally arranged on the screw above the limiting rod.

[0012] Furthermore, the limiting rod has a strip-shaped hole along the width direction of the carriage, and strip-shaped grooves are formed on both sides of the strip-shaped hole inwards towards the hole wall. Sliding blocks are slidably arranged in the two strip-shaped grooves. Sliding holes are formed vertically on the sliding blocks.

[0013] In summary, this utility model has the following beneficial effects: In this application, by setting a positioning component and a limiting component, when the steel coil is placed on the bottom plate, the drive components located at the front and rear ends of the bottom plate drive the positioning component to move towards the middle and abut against the front and rear sides of the steel coil. Then, the triangular support base is fixedly connected to the bottom plate by bolts, thereby ensuring that the positioning component is firmly fixed on the bottom plate, preventing the steel coil from sliding due to inertia caused by vehicle braking, which could damage the drive component or even cause injury or death to the front of the vehicle and personnel. The limiting components on both sides abut and limit the steel coil on both sides, preventing the steel coil from shifting laterally during vehicle bumps or turns, thus preventing it from affecting vehicle stability.

Detailed Implementation

[0022] 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.

[0023] like Figure 1-8 As shown in the embodiment of this application, a protective device for transporting building materials is disclosed, including a floor plate 10 fixedly installed on the carriage. Two sets of positioning components 20 and two sets of limiting components 40 are provided on the floor plate 10. The two sets of positioning components 20 position the front and rear sides of the steel coil, and the two sets of limiting components 40 limit the left and right sides of the steel coil, thereby fixing the steel coil on the carriage and preventing the steel coil from shifting during vehicle transportation and causing safety accidents.

[0024] Specifically, two transverse sliding grooves 11 are symmetrically formed on the front and rear sides of the base plate 10 along the transverse centerline of the base plate 10. The length direction of the transverse sliding grooves 11 is consistent with the length direction of the carriage. Two sets of positioning components 20 are slidably disposed on the transverse sliding grooves 11 on both sides. The positioning component 20 includes a positioning seat 21, which includes a vertically arranged positioning plate 211 and a positioning block 212. The bottom edge of the positioning plate 211 is provided with a first slider 215 corresponding to the transverse sliding groove 11, and the bottom edge of the positioning block 212 is provided with a second slider 216 corresponding to the transverse sliding groove 11, so that the positioning plate 211 and the positioning block 212 can slide within the transverse sliding groove 11. The positioning block 212 is disposed inside the positioning plate 211, and the side away from the positioning plate 211 is a curved surface that mates with the steel coil, so that the positioning block 212 can fit against the curved surface of the steel coil, thereby maximizing the stability of the steel coil. A T-shaped groove 213 is vertically provided on the side of the positioning plate 211 adjacent to the steel coil. A T-shaped protrusion 214 is correspondingly provided on the side of the positioning block 212 adjacent to the positioning plate 211. The T-shaped protrusion 214 cooperates with the T-shaped groove 213, so that the positioning block 212 can be detachably mounted on the positioning plate 211. In this way, positioning blocks 212 with different curved surfaces can be replaced according to different specifications of the steel coil to provide the best support for the steel coil.

[0025] A fixing plate 23 is also provided on the side of the positioning plate 211 away from the steel coil. A third slider 231 is provided on the bottom edge of the fixing plate 23 corresponding to the transverse slide groove 11, so that the fixing plate 23 can slide within the transverse slide groove 11. A triangular support base 22 is provided on the side of the fixing plate 23 away from the positioning plate 211. The triangular support base 22 includes a horizontal plate 222, a vertical plate 223, and a triangular support plate 224. The surface of the vertical plate 223 is attached to and fixedly connected to the surface of the fixing plate 23. Two rows of four vertical fixing holes 221 are provided on the horizontal plate 222. Two rows of bolt holes 12 are provided on the bottom plate 10 along the length of the transverse slide groove 11. The hole spacing between two adjacent bolt holes 12 in each row is half the hole spacing between two vertical fixing holes 221 in the same row on the horizontal plate 222. After the triangular support 22 slides into position within the transverse groove 11 along with the fixing plate 23, bolts can be used to fix the triangular support 22 to the base plate 10 through the fixing holes and bolt holes 12, thereby fixing the fixing plate 23 to the base plate 10 and providing sufficient oblique support force towards the steel coil. A plurality of springs 24 arranged in an array are connected between the fixing plate 23 and the positioning plate 211. When the vehicle brakes or decelerates, the steel coil moves forward due to inertia, pushing the positioning seat 21 forward to compress the springs 24. The array of springs 24 absorbs some of the impact force, achieving a buffering effect on the steel coil and preventing it from rushing into the cab and causing a safety accident.

[0026] The base plate 10 is provided with a drive assembly 30 at both the front and rear ends for driving the positioning seat 21 to slide along the transverse slide groove 11. The drive assembly 30 includes a pad 31 at both the front and rear ends of the base plate 10. An electric push rod 32 is provided on the pad 31. The push rod end of the electric push rod 32 is connected to the vertical plate 223 of the triangular support 22, thereby pushing the triangular support 22, the fixing plate 23, and the positioning seat 21 to slide in the transverse slide groove 11 through the electric push rod 32.

[0027] A further configuration involves two longitudinal grooves 13 symmetrically formed along the longitudinal centerline of the base plate 10 on both the left and right sides. The length direction of the longitudinal grooves 13 is consistent with the width direction of the carriage. Two sets of limiting components 40 are slidably disposed on the longitudinal grooves 13 on both sides. Each limiting component 40 includes a limiting seat 41, and a longitudinal slider 411 is provided at the bottom of the limiting seat 41 corresponding to the longitudinal groove 13, allowing the limiting seat 41 to slide within the longitudinal groove 13. Fixed seats 42 are provided on the left and right sides of the base plate 10, and threaded holes 421 are formed on the fixed seats 42. Threaded rods 43 are rotatably disposed within the threaded holes 421. A through hole 412 is provided on the limiting seat 41. A circular groove 413 larger than the diameter of the through hole 412 is opened at the inner end of the limiting seat 41. The end of the threaded rod 43 near the limiting seat 41 passes through the through hole 412 and enters the groove 413, and a circular baffle 431 is provided at the end. The diameter of the circular baffle 431 is larger than the diameter of the through hole 412 and smaller than the diameter of the groove 413, so that the threaded rod 43 can rotate within the limiting seat 41. However, due to the cooperation between the baffle 431 and the groove 413, the threaded rod 43 cannot be pulled out from the groove 413. The end of the threaded rod 43 away from the limiting seat 41 is located outside the fixed seat 42 and a turntable 432 is provided at the end. A rotating shaft 433 is provided on the turntable 432. The drive shaft 433 drives the turntable 432 to rotate, causing the threaded rod 43 to rotate. Under the action of the threaded hole 421, the threaded rod 43 drives the limit seat 41 to move horizontally, thereby driving the limit seat 41 to slide in the longitudinal groove 13.

[0028] A locking nut 44 is provided on the threaded rod 43 located between the limiting seat 41 and the fixed seat 42. After the limiting seat 41 is pressed against the side of the steel coil, the locking nut 44 is screwed toward the fixed seat 42 until it is tightly against the fixed seat 42. This locks the threaded rod 43, preventing the limiting seat 41 from moving toward the fixed seat 42 and avoiding displacement of the limiting seat 41 due to the threaded rod 43 loosening during vehicle travel.

[0029] Furthermore, a notch 45 is vertically formed in the middle of the limiting seat 41, and a screw 46 is vertically arranged within the notch 45. A limiting rod 47 is vertically slidably mounted on the screw 46. A strip-shaped hole 471 is formed on the limiting rod 47 along the width direction of the carriage. Strip-shaped grooves 472 are formed on both sides of the strip-shaped hole 471 and extend inward toward the hole wall. Sliding blocks 473 are slidably mounted in the two strip-shaped grooves 472. A sliding hole 474 is vertically formed on the sliding block 473. During installation, the sliding block 473 is sleeved onto the screw 46 through the sliding hole 474. The sliding block 473 will not move in the horizontal direction, thus allowing the limiting rod 47 to slide relative to the sliding block 473 in the horizontal direction. The width of the limiting rod 47 is set to be the same as the width of the notch 45, so that the limiting rod 47 cannot rotate relative to the screw 46, thus limiting the limiting rod 47. Ultimately, the limiting rod 47 can only move up and down on the screw 46 with the sliding block 473 and slide relative to the sliding block 473 in the width direction of the carriage. In the initial state, the limiting rod 47 can be slid to its inner side near the screw 46, which will not affect the loading of the steel coil. After the steel coil is placed, the limiting rod 47 is slid into the inner hole of the steel coil, and then the limiting rod 47 moves downward until the bottom edge of the limiting rod 47 contacts the inner ring of the steel coil. Specifically, the two edges at the bottom of the limiting rod 47 are rounded to increase the contact area between the limiting rod 47 and the inner ring of the steel coil, while avoiding indentation on the steel coil. A fixing nut 48 is screwed onto the screw 46 above the limiting rod 47. When the limiting rod 47 contacts the inner ring of the steel coil, the fixing nut 48 is screwed downwards to press the limiting rod 47 tightly against the inner ring of the steel coil, thereby limiting the vertical movement of the steel coil and preventing it from swaying due to vehicle bumps. Two fixing nuts 48 are provided to achieve a locking effect, preventing the fixing nuts 48 from loosening due to vehicle bumps.

[0030] The operating principle of the building material transportation protection device in this embodiment is as follows: First, replace the appropriate positioning block 212 according to the specifications of the steel coil to be transported. Then, the steel coil is hoisted onto the bottom plate 10. The electric push rods 32 at both ends push the triangular support seat 22, the fixing plate 23, and the positioning seat 21 to slide in the transverse slide groove 11 towards the steel coil until the curved surface of the positioning block 212 on the positioning seat 21 is in contact with the steel coil. Then, use bolts to fix the triangular support seat 22 to the bottom plate 10, thereby positioning the front and rear sides of the steel coil. Then, manually rotate the rotating shaft 433 and rotate it so that the threaded rod 43 rotates and drives the limiting seat 41 to move towards the steel coil until the limiting seat 41 is in contact with the end face of the steel coil. Then, tighten the locking nut 44 to lock the threaded rod 43 and fix the limiting seat 41, thereby positioning the left and right ends of the steel coil. Then, slide the limiting rod 47 so that the limiting rod 47 is pressed against the inner ring of the steel coil. Tighten the fixing nut 48 to fix it, thereby limiting the steel coil in the vertical direction. This allows for comprehensive positioning of the steel coil, effectively preventing displacement during transportation and reducing the risks associated with transporting the steel coil.

[0031] 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.
