Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a novel flatbed truck for transporting large-volume prefabricated components. Background Art

[0002] Traditional prefabricated component transport carriages take a lot of time to fix and untie prefabricated components, resulting in low transportation efficiency. In addition, for prefabricated components that are too high, the transport stability of the transport carriage is poor, and it is easy to overturn in mountainous terrain with excessively steep slopes, which is very dangerous. In addition, when the prefabricated component is arched, its irregular shape causes the center of gravity of the prefabricated component to be more unstable during transportation, making it more prone to overturning. Summary of the invention

[0003] In view of this, the present invention discloses a novel large-volume prefabricated component transport flatbed vehicle, which aims to solve the problem that the arched prefabricated components are prone to overturning during transportation.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A novel flatbed truck for transporting large-volume prefabricated components comprises a vehicle body and a power device for driving the vehicle body to move, wherein two bases are detachably connected to the vehicle body in sequence along its traveling direction, each of the bases is provided with a slide groove, each of the inner edges of the slide groove is slidably connected to a base, and a locking pin is detachably connected between the base and the slide groove; a mounting seat is vertically slidably arranged on the base, and a vertical hydraulic cylinder for pushing the mounting seat to move vertically is arranged on the base; a support frame is hinged on the mounting seat, the longitudinal section of the support frame is arc-shaped, and an adjusting hydraulic cylinder for pushing the support frame is hinged between the mounting seat and the side wall of the support frame.

[0006] In this solution, the position of the support frame is adjusted by sliding the base and the mounting seat, and then the support frame is pushed to deflect by adjusting the hydraulic cylinder, so that the support frame faces the two ends of the arched prefabricated component respectively, and then the prefabricated component is hoisted, and the ends of the prefabricated component are placed in the arc-shaped support frame to form a relatively stable support. In addition, the position of the support frame can be adjusted through structures such as the base, and then the height of the two ends of the arched prefabricated component can be adjusted to adjust the center of gravity of the prefabricated component so that the center of gravity of the prefabricated component is in the middle of the vehicle body, reducing the probability of the prefabricated component overturning during transportation.

[0007] Furthermore, a load-bearing seat detachably connected to the end of the prefabricated component is slidably connected inside the support frame, and the sliding trajectory of the load-bearing seat is concentric with the support frame, a main hydraulic energy absorber is hinged between the load-bearing seat and the inside of the support frame, and a shear rod is connected between the load-bearing seat and the support frame; openings are provided at opposite ends of the support frame, a fixed rod is hinged at the opening, a moving rod is slidably sleeved at the end of the fixed rod, a positioning pin is detachably connected between the fixed rod and the moving hook, and an arc-shaped baffle is also provided at the opening, a spacing is reserved between the baffle and the load-bearing seat, the baffle is concentric with the support frame, and the baffle is detachably hinged to the corresponding end of the moving rod.

[0008] In this solution, the end of the prefabricated component is connected and fixed to the load-bearing seat, and then the baffle is fitted to the surface of the prefabricated component, and then the moving rod is connected to the baffle, and the positioning pin is installed; when the vehicle body brakes suddenly, the prefabricated component moves forward due to inertia, and the baffle is used to guide the prefabricated component to a certain extent. The prefabricated component acts on the load-bearing seat to break the shear rod, so that the load-bearing seat slides in the support frame, and the load-bearing seat is used to squeeze or stretch the main hydraulic energy absorber, thereby playing an energy dissipation role; in addition, the moving direction of the end of the prefabricated component is converted into a direction close to vertical, and the force of the prefabricated component is vertically transmitted to the vehicle body, so as to avoid the end of the prefabricated component being subjected to horizontal forces, thereby preventing the end of the prefabricated component from being sheared and broken.

DETAILED DESCRIPTION

[0023] like Figures 1 to 5 As shown:

[0024] A novel flatbed truck for transporting large-volume prefabricated components 23 comprises a vehicle body 1 and a power device for driving the vehicle body 1 to move (conventional technical means, so not shown in the figure), the vehicle body 1 is detachably connected with two bases 2 in sequence along its traveling direction, the bases 2 are each provided with a slide groove, the inner edge of the slide groove is slidably connected with a base 3, and a locking pin is detachably connected between the base 3 and the slide groove; a mounting seat 4 is vertically slidably arranged on the base 3, and a vertical hydraulic cylinder 6 for pushing the mounting seat 4 to move vertically is arranged on the base 3; a support frame 5 is hinged on the mounting seat 4, the longitudinal section of the support frame 5 is arc-shaped, and an adjusting hydraulic cylinder for pushing the support frame 5 is hinged between the mounting seat 4 and the side wall of the support frame 5.

[0025] In this solution, the position of the support frame 5 is adjusted by sliding the base 3 and the mounting seat 4, and then the support frame 5 is pushed to deflect by adjusting the hydraulic cylinder, so that the support frame 5 faces the two ends of the arched prefabricated component 23 respectively, and then the prefabricated component 23 is hoisted, and the ends of the prefabricated component 23 are placed in the arc-shaped support frame 5 to form a relatively stable support. In addition, the position of the support frame 5 can be adjusted through the structure such as the base 2, and then the height of the two ends of the arched prefabricated component 23 can be adjusted, so as to adjust the center of gravity of the prefabricated component 23, so that the center of gravity of the prefabricated component 23 is in the middle of the vehicle body 1, reducing the probability of the prefabricated component 23 overturning during transportation.

[0026] In this embodiment, a load-bearing seat 8 detachably connected to the end of the prefabricated component 23 is slidably connected inside the support frame 5, and the sliding trajectory of the load-bearing seat 8 is concentric with the support frame 5, a main hydraulic energy absorber 9 is hinged between the load-bearing seat 8 and the inside of the support frame 5, and a shear rod 20 is connected between the load-bearing seat 8 and the support frame 5; openings for the prefabricated component 23 to enter and exit are provided at the opposite ends of the support frame 5, and fixed rods 10 are hinged at the openings, and a moving rod 11 is slidably sleeved on the end of the fixed rod 10, and a positioning pin is detachably connected between the fixed rod 10 and the moving hook, and an arc-shaped baffle 12 is also provided at the opening, a spacing is reserved between the baffle 12 and the load-bearing seat 8, and the baffle 12 is concentric with the support frame 5, and the baffle 12 is detachably hinged to the corresponding end of the moving rod 11.

[0027] In this solution, the end of the prefabricated component 23 is connected and fixed to the load-bearing seat 8, and then the baffle 12 is fitted with the surface of the prefabricated component 23, and then the moving rod 11 is connected to the baffle 12, and the positioning pin is installed; when the vehicle body 1 brakes suddenly, the prefabricated component 23 moves forward due to inertia, and the baffle 12 is used to guide the prefabricated component 23 to a certain extent. The prefabricated component 23 acts on the load-bearing seat 8 to cause the shear rod 20 to break due to the shear force, so that the load-bearing seat 8 slides in the support frame 5, and the load-bearing seat 8 is used to squeeze or stretch the main hydraulic energy absorber 9, thereby playing an energy dissipation role; in addition, the moving direction of the end of the prefabricated component 23 is converted into a direction close to the vertical, and the force of the prefabricated component 23 is vertically transmitted to the vehicle body 1, so as to avoid the end of the prefabricated component 23 from being subjected to the force in the horizontal direction, and to prevent the end of the prefabricated component 23 from being sheared and broken.

[0028] In this embodiment, a guide structure is provided between the slide grooves, and the guide structure includes a plurality of support members 14 vertically arranged on the vehicle body 1. The support member 14 is a telescopic structure. The support member 14 in this embodiment adopts a hydraulic cylinder structure. A U-shaped support 13 is provided on the top of the support member 14. Two parallel support limit cylinders are provided between the two ends of the support 13. Both ends of the support limit cylinder are rotatably connected with a connecting seat 16, and the connecting seat 16 is detachably connected to the corresponding end of the support 13.

[0029] In this solution, the support 14 is extended and retracted to make the support 13 cover the prefabricated component 23, and then the connecting seat 16 and the support limiting cylinder are installed so that the two support limiting cylinders on the same support 13 clamp the prefabricated component 23; when the prefabricated component 23 moves, the support limiting cylinder is used to clamp and limit the prefabricated component 23, and the lateral movement of the prefabricated component 23 is converted into a circular motion with the center of the prefabricated component 23, which plays a guiding role and prevents the prefabricated component 23 from moving lateral to cause shear fracture at its end.

[0030] In this embodiment, a groove is provided on the end face of the connecting seat 16 facing the support limit cylinder, a coaxial annular groove is provided on the side of the groove, a plurality of energy-absorbing grooves facing the central axis thereof are provided on the side walls of the annular groove, and auxiliary hydraulic energy-absorbing devices facing the central axis of the groove are coaxially arranged in the energy-absorbing groove; both ends of the support limit cylinder extend into the groove and are rotatably connected thereto, and an arc-shaped protrusion 18 for pushing the output end of the auxiliary hydraulic energy-absorbing device is provided at the end of the support limit cylinder.

[0031] In this solution, when the prefabricated component 23 moves, the friction between the prefabricated component 23 and the support limit cylinder is used to drive the support limit cylinder to rotate, and the arc-shaped protrusion 18 at the end of the support limit cylinder rotates synchronously. The arc-shaped protrusion 18 is used to push the output end of the auxiliary hydraulic energy consumption device, thereby playing a role in auxiliary energy consumption.

[0032] In this embodiment, a plurality of positioning holes 19 are opened on the inner wall of the support frame 5, and limiting holes corresponding to the positioning holes 19 are arranged on both sides of the load-bearing seat 8. The shear rod 20 is slidably connected in the limiting hole, and an elastic support member 14 is arranged between the limiting hole and the shear rod 20 (conventional technical means, so it is not drawn in the figure), and a shear groove 21 is arranged at one end of the shear rod 20 facing the support frame 5.

[0033] By setting the shear groove 21, when the shear rod 20 is inserted into the positioning hole 19, the contact surface of the load-bearing seat 8 and the supporting frame 5 is opposite to the shear groove 21. When the load-bearing seat 8 is under excessive pressure, the shear rod 20 breaks along the shear groove 21; when the function of the prefabricated component 23 is released, such as when the shear rod 20 is opposite to a positioning hole 19, the shear rod 20 is inserted into the positioning hole 19 under the action of the elastic support member 14, playing a role of auxiliary temporary support.

[0034] In this embodiment, a plurality of rollers 22 are disposed on the baffle 12 .

[0035] The rollers 22 are provided to reduce the wear between the baffle plate 12 and the prefabricated component 23 .

[0036] In this embodiment, a rubber cushion layer is provided on the supporting and limiting cylinder.

[0037] By providing the rubber cushion layer, the friction between the support and limit cylinder and the prefabricated component 23 is strengthened, thereby driving the support and limit cylinder to rotate more, and at the same time, the wear on the prefabricated component 23 can be reduced.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
