Description

Technical Field

[0001] This utility model relates to a transport vehicle used for steel structure roof construction, belonging to the field of building construction technology. Background Technology

[0002] A steel structure roof mainly consists of steel roof trusses, purlins, and roof panels. The steel roof trusses, constructed from interconnected steel structures, are the primary load-bearing and supporting structure. Purlins, typically C-shaped or H-shaped steel, support the roof panels and distribute the forces transmitted from the roof panels to the steel roof trusses. The roof panels, usually made of metal, fiberglass, or composite materials, are laid on top of the purlins and serve to provide waterproofing, sun protection, and withstand external loads. Before installation, the roof panels are lifted to the top of the steel roof trusses using a crane and neatly stacked, avoiding the center of the purlins. Subsequently, the roof panels are manually moved from the stacking location for installation as needed. Manual handling is time-consuming, labor-intensive, inefficient, and poses significant safety hazards. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a transport vehicle for steel structure roof construction, which is equipped with a limiting component to prevent the roof panel from slipping off the frame and to facilitate the horizontal movement of the roof panel from the front to the frame.

[0004] This utility model achieves the above objectives by adopting the following technical solutions:

[0005] A transport vehicle for steel structure roof construction includes a frame. Two mounting shafts are respectively provided on the left and right sides of the frame. The mounting shafts extend in the left-right direction and rollers are coaxially mounted on the mounting shafts. A limiting assembly is provided on the frame. The limiting assembly includes a trigger plate and a lever. The trigger plate is located above the frame. The lever extends in the front-rear direction. The rear end of the lever is connected to the bottom of the trigger plate. The front end of the lever extends to the lower front of the frame. The middle part of the lever is rotatably connected to the frame via a pivot. An upwardly extending stop bar is provided at the top of the front end of the lever. When no external force is applied, the front end of the lever droops down so that the stop bar is lower than the trigger plate. When an external force is applied, the lever rotates around the pivot so that the stop bar is higher than the trigger plate.

[0006] Optionally, the frame is provided with a limiting groove, through which the front part of the lever passes, and the limiting groove is used to constrain the rotation angle of the lever around the pivot.

[0007] Optionally, the roller is rotatably connected to the mounting shaft, and a guide assembly is also installed on each mounting shaft. The guide assembly includes a limiting wheel disposed below the roller, the axle of the limiting wheel is arranged vertically, the limiting wheel is rotatably mounted on the mounting base, and the mounting base is fixed on the mounting shaft.

[0008] Optionally, the limiting wheel is mounted on a wheel axle seat, the mounting seat is provided with a strip hole, the wheel axle seat is connected to the strip hole through a bolt and nut assembly, and the bolt and nut assembly can move up and down within the strip hole.

[0009] Optionally, a handle is provided on the rear side of the frame.

[0010] Optionally, the bottom of the handle is fixed to the frame, and the upper part of the handle extends upward and backward at an angle.

[0011] Optionally, the handle is a telescopic handle, or a connecting tube is provided at the bottom rear side of the frame, and the bottom of the handle is threadedly connected to the connecting tube.

[0013] Optionally, the front end of the lever is provided with a pry bar, which extends forward past the stop bar.

[0014] The beneficial effects of this application include, but are not limited to:

[0015] This utility model provides a transport vehicle for steel structure roof construction, which features a limiting component on the frame to hold the roof panels on the frame and prevent them from slipping. The limiting component includes a trigger plate and a lever. When no external force is applied, the front end of the lever droops down, causing the stop bar to be lower than the trigger plate. This allows the stacked roof panels to be easily moved horizontally from the front onto the frame. When the roof panel is placed on the frame and presses against the trigger plate, the trigger plate moves down, causing the lever to rotate around its axis. This causes the stop bar at the front end of the lever to be higher than the trigger plate, thus preventing the roof panel from slipping off the frame. Furthermore, this utility model also includes a guide component on the frame, which can constrain the rollers to move on top of the purlins. Attached Figure Description

Detailed Implementation

[0024] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0025] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1 As shown, the transport vehicle for steel structure roof construction provided by this utility model includes a frame 100. Two mounting shafts 210 are respectively provided on the left and right sides of the frame 100. The mounting shafts 210 extend in the left and right direction, and rollers 220 are coaxially mounted on the mounting shafts 210. When transferring roof panels, the roof panels are placed on the top of the frame 100, and the frame 100 is dragged to move to the required position.

[0027] To prevent the roof panel from wobbling and slipping off the frame 100, this invention provides a limiting component on the frame 100 to keep the roof panel on the frame 100.

[0028] Specifically, the limiting assembly includes a trigger plate 310 and a lever 320. The trigger plate 310 is positioned above the frame 100, and the lever 320 extends in the front-rear direction. The rear end of the lever 320 is connected to the bottom of the trigger plate 310, and the front end of the lever 320 extends to the lower front of the frame 100. The middle part of the lever 320 is rotatably connected to the middle part of the frame 100 via a pivot 330, and an upwardly extending stop bar 340 is provided at the top of the front end of the lever 320.

[0029] When transferring roof panels, push the transport vehicle forward towards the location where the roof panels are stacked. For example... Figure 2 As shown, when there is no external force, the front end of the lever 320 droops down, causing the stop bar 340 to be lower than the trigger plate 310, at which time the stacked roof panels can be easily moved from the front side onto the frame 100.

[0030] When the roof panel 2 is placed on the frame 100 and presses against the trigger plate 310, as Figure 3 As shown, the trigger plate 310 will move downward, causing the lever 320 to rotate around the pivot 330, so that the stop bar 340 at the front end of the lever 320 is higher than the trigger plate 310. In this way, the stop bar 340 can block the front side of the roof panel, preventing the roof panel from slipping off the frame 100.

[0031] Preferably, the upper end of the stop lever is bent towards the rear of the frame, which can restrain the roof panel on the frame. Furthermore, a pry bar 321 is provided at the front end of the lever 320, and the pry bar 321 extends forward past the stop lever 340. Figure 4 As shown, when unloading roof panels, the transport vehicle is pushed closer to the stacked roof panels. The pry bar will be inserted under the slope of the roof panel. As the transport vehicle continues to move forward, the lever will rotate around the pivot, causing the stop bar to tilt, and the roof panel can be smoothly unloaded from the transport vehicle.

[0032] After the roof panel is removed from the frame 100, the pressure on the trigger plate 310 is removed, and the front end of the lever 320 will droop under the action of torque, so that the stop bar 340 is lower than the trigger plate 310, making it convenient for the next transfer.

[0033] Typically, the distance between the trigger plate 310 and the pivot 330 is less than the distance between the stop lever 340 and the pivot 330, and the trigger plate 310 is made of a low-density material so that the front end of the lever 320 can hang down smoothly.

[0034] Furthermore, a limiting groove 350 is provided on the frame 100, through which the front part of the lever 320 passes. The function of the limiting groove 350 is to constrain the rotation angle of the lever 320 around the pivot 330, preventing the front end of the lever 320 from drooping excessively and affecting the movement of the transport vehicle. Alternatively, other components can be used to constrain the rotation angle of the lever 320; for example, a crossbar can be provided below the frame 100, allowing the lever 320 to pass between the frame 100 and the crossbar. The limiting groove 350 can be located at the front of the frame, and has a certain vertical extension depth, allowing the lever to tilt upwards normally while preventing excessive drooping of the lever 320.

[0035] Typically, two levers (320) are provided to improve the stability of the transport vehicle during operation.

[0036] When the transport vehicle moves on the roof, the rollers need to remain on top of the purlin 1 and the direction of travel cannot be deviated. To this end, the present invention also installs a guide assembly on each mounting shaft 210, which serves to constrain the rollers 220 to the top of the purlin 1.

[0037] Specifically, the guide assembly includes a limiting wheel 410 disposed below the roller 220. The axle of the limiting wheel 410 is vertically arranged, and the limiting wheel 410 is rotatably mounted on the mounting base 420, which is fixed to the mounting shaft 210. At this time, the mounting shaft 210 should be fixedly connected to the frame 100, and the roller 220 is coaxially rotatably connected to the mounting shaft 210. The mounting base 420 can be made of perforated steel plate, and the limiting wheel 410 is mounted on the mounting base 420 via a wheel bracket.

[0038] Roofs typically have a certain slope, so they can be... Figure 5 As shown, the limiting wheel 410 is positioned at the end of the fixed shaft with a higher slope, causing the limiting wheel 410 to roll against the side of the purlin with a higher slope. Alternatively, it can be arranged as follows... Figure 6 As shown, the limiting wheel 410 is set at the end of the rotating shaft 330 outside the roller 220, so that the limiting wheels 410 on the left and right sides press against the outer sides of the two purlins that are far apart and roll, preventing the transport vehicle from leaving the purlins to the left or right.

[0039] In a preferred embodiment, the limiting wheel is mounted on a wheel axle seat. The mounting seat has a slotted hole, and the wheel axle seat is connected to the slotted hole via a bolt and nut assembly, which can move up and down within the slotted hole. When the purlin is made of C-shaped steel, the height of the limiting wheel can be adjusted to move it to the upper part of the C-shaped steel's groove, keeping the limiting wheel within the groove and preventing the transport vehicle from derailing.

[0040] Furthermore, in practical applications, the position of the mounting base 420 can be determined according to the direction of the roof slope and the direction of the C-shaped steel, so that the limiting wheel 410 can be located in the groove of the C-shaped steel.

[0041] Among them, the wheel axle seat is a connecting component that connects the limit wheel and the mounting base, which is a conventional existing structure.

[0042] In a preferred embodiment, a handle 500 is provided on the rear side of the frame 100, which can facilitate the towing of the transport vehicle and also limit the roof panel on the frame 100. It works in conjunction with the stop bar 340 on the lever 320 to prevent the roof panel from slipping off the frame 100.

[0043] Furthermore, the bottom of the handle 500 can be fixed to the frame 100, and the upper part of the handle 500 can be tilted upward and backward to facilitate the construction personnel to push the transport vehicle.

[0044] Furthermore, the handle can be configured as a telescopic handle or a detachable structure. The telescopic handle can be achieved using conventional methods found in existing technology; for example, a connecting tube can be installed at the bottom rear of the frame, with the bottom of the handle threadedly connected to the connecting tube. When it is necessary to remove the roof panel from the rear of the frame, the handle can be shortened or removed.

[0045] Furthermore, the top of the frame is covered with anti-slip pads to prevent the roof panels from slipping off the frame.

[0046] It should be noted that this utility model does not impose specific restrictions on the structure of the frame 100. Considering factors such as simplifying the structure, reducing pressure on the roof, and not interfering with the rotation of the lever 320, the frame 100 shown in the attached drawings consists of an outer frame and several longitudinal beams.
