Description

Technical Field

[0001] This utility model relates to the field of steel bar loading technology, and in particular to a steel bar loading vehicle. Background Technology

[0002] In the fields of building construction and steel bar processing, the loading of steel bars relies on manual labor or simple loading vehicles. Since steel bars have a certain length and weight, manual handling requires the cooperation of multiple people, which is labor-intensive and has low loading efficiency. When loading is done by loading vehicle, the steel bars are stacked haphazardly, and assistance is needed to adjust and straighten them during loading. Furthermore, the loading vehicle lacks protection when moving, making it prone to collisions with operators or objects in the work area, which can easily lead to danger. Utility Model Content

[0003] The purpose of this utility model is to provide a steel bar loading vehicle that allows the transported steel bars to be neatly arranged and reduces the possibility of collisions with other operators or objects.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0006] A vehicle body, on which a traveling assembly is provided, the traveling assembly being able to propel the vehicle body to move;

[0007] A support assembly includes a frame and support beams, with multiple frames spaced apart along a first direction of the vehicle body; the support beams are disposed on the frames to limit and support reinforcing bars.

[0008] A light curtain assembly, comprising a generator and a receiver, wherein the generator and the receiver are fixed to opposite ends of the vehicle body and extend out of the vehicle body, and the light curtain assembly is connected to the traveling assembly via a control system.

[0009] In some embodiments, at least a portion of the support beams are height-adjustable on the frame.

[0010] In some embodiments, the support beam is provided with fixing plates at both ends, and the fixing plates are provided with first fixing holes; the frame is provided with a plurality of second fixing holes spaced apart along its height direction, and the support beam is fixed to the frame by connectors inserted into the first fixing holes and the second fixing holes.

[0011] In some embodiments, multiple support beams are provided on any one of the frames, and the multiple support beams on the same frame are distributed along a second direction of the frame, the second direction being perpendicular to the first direction.

[0012] In some embodiments, the frame includes a bottom beam and longitudinal beams, the bottom beam extending along the second direction, a plurality of longitudinal beams being fixed at intervals along the second direction to the bottom beam, and a support beam being disposed between at least some of the adjacent longitudinal beams.

[0013] In some embodiments, the longitudinal beam is further provided with a first plate and a second plate, a first end of the first plate being connected to a first end of the second plate, and a second end of the first plate and a second end of the second plate being spaced apart on the top of the longitudinal beam along the second direction, so as to guide the reinforcing bars entering between adjacent longitudinal beams.

[0014] In some embodiments, the vehicle body is further provided with a supporting hopper, which is located at the end of the vehicle body along the first direction.

[0015] In some embodiments, the supporting hopper is provided with a supporting groove corresponding to the supporting beam.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1 to 6 As shown, this application provides a rebar loading vehicle, which includes a vehicle body 1, a support assembly 3, and a light curtain assembly 4. A traveling assembly 2 is mounted on the vehicle body 1, enabling the vehicle body 1 to move. The support assembly 3 includes a frame 31, with multiple frames 31 spaced apart along a first direction of the vehicle body 1 (the first direction is...). Figure 1 (X direction in the middle); the support beam 32 is set on the frame 31 to limit and support the steel bars; the light curtain assembly 4 includes a generator 41 and a receiver 42, the generator 41 and the receiver 42 are fixed at opposite ends of the vehicle body 1 and extend out of the vehicle body 1, and the light curtain assembly 4 is connected to the walking assembly 2 through the control system.

[0039] The aforementioned support component 3 allows the reinforcing bars to be placed on the support beam 32 along the first direction for limiting and supporting them. Furthermore, the movement of the vehicle body 1 moves the limited and supported reinforcing bars to a designated position for loading. In this state, the reinforcing bars remain in the first direction, ensuring neat placement and eliminating the need for direction adjustment or straightening during loading. Additionally, the vehicle body 1 can ensure safe movement under the light curtain formed by the light curtain component 4. If a person or object is located in the movement path of the vehicle body 1, the movement can be stopped promptly after identification by the light curtain, minimizing the risk of accidents.

[0040] like Figure 1 As shown, in some embodiments, the vehicle body 1 includes two main beams 11 extending along a first direction, and the two main beams 11 are spaced apart along a second direction (the second direction is...). Figure 1The first direction, the second direction, and the height direction of the vehicle body 1 are perpendicular to each other, and several connecting beams 12 connect the two main beams 11. The frame 31 is connected to the two opposite main beams 11. The number of frame 31 distributed along the first direction is not specifically limited and can be determined according to the required steel bar length.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, multiple support beams 32 are provided on any one frame 31. The multiple support beams 32 on the same frame 31 are distributed along the second direction of the frame 31. Through the multiple support beams 32 distributed along the second direction, multiple rows of parallel steel bars can be supported along the second direction, further improving the efficiency of material loading. Specifically, the frame 31 includes a bottom beam 311 and longitudinal beams 312. The bottom beam 311 extends along the second direction and is provided on the vehicle body 1. Multiple longitudinal beams 312 are fixed to the bottom beam 311 at intervals along the second direction. Support beams 32 are provided between at least some of the adjacent longitudinal beams 312, so that the support beams 32 and the longitudinal beams 312 limit and support the steel bars. For example, ten longitudinal beams 312 are provided on the same bottom beam 311. No support beam 32 is provided between the two middle longitudinal beams 312, so that the frame 31 distributed along the first direction forms a walking passage 36 between the two middle longitudinal beams 312. Reinforcing bars are supported on the support beams 32 on both sides of the walking passage 36. The walking passage 36 allows operators to walk and easily arrange the reinforcing bars on the support beams 32 when needed. More specifically, a ladder 6 is provided at one end of the vehicle body 1 along the first direction, facilitating operator access to the walking passage 36. In this embodiment, the support beam 32 can be a straight rod or a straight plate, or it can be a U-shaped rod or a U-shaped plate.

[0042] It should be noted that the distance between two adjacent longitudinal beams 312 on the same frame 31 along the second direction may not be the same, so that the frame 31 can form placement spaces of different sizes in the second direction, thereby supporting steel bars of different sizes.

[0043] When a long steel bar is supported on the support beam 32 along the first direction, the end of the steel bar is prone to sagging due to gravity, causing wear on the end of the steel bar during the movement of the vehicle body 1. To avoid this phenomenon, such as Figure 1As shown, in some embodiments, the vehicle body 1 also has a supporting hopper 5, which is disposed at one end of the vehicle body 1 along the first direction. In the current embodiment, the supporting hopper 5 and the ladder 6 are disposed opposite each other at both ends of the vehicle body 1. The supporting hopper 5 is used to support the ends of the reinforcing bars. In order to further play a limiting role, a supporting groove 51 is provided in the supporting hopper 5. The supporting groove 51 is formed by adjacent limiting posts and corresponds to the supporting beam 32, so that the supporting groove 51 can limit the ends of the reinforcing bars supported on the supporting beam 32 along the first direction.

[0044] In some embodiments, to accommodate different gripping heights, at least some of the support beams 32 on the frame 31 are height-adjustable, thereby enabling at least a partial lifting of the reinforcing bar in the first direction for easy gripping. In the current embodiment, at least one support beam 32 on the frame 31 near the hopper 5 is height-adjustable. For example, seven frames 31 are provided along the first direction, wherein the support beams 32 on the four frames 31 near the hopper 5 are height-adjustable.

[0045] Specifically, such as Figure 2 As shown, the support beam 32 is provided with fixing plates 33 at both ends, and the fixing plates 33 are provided with first fixing holes. The longitudinal beam 312 is provided with second fixing holes at intervals along its height direction. The support beam 32 is fixed by connectors inserted into the first fixing holes and the second fixing holes. The connectors may be, but are not limited to, bolts or plugs. When bolts are used, the second fixing holes may be screw holes.

[0046] like Figure 2 As shown, in some embodiments, the longitudinal beam 312 is further provided with a first plate 34 and a second plate 35, wherein the first end of the first plate 34 is connected to the first end of the second plate 35, and the second ends of the first plate 34 and the second plate 35 are spaced apart along a second direction at the top of the longitudinal beam 312, thereby guiding the reinforcing bars entering the support beam 32 for support through the triangular guide plate formed by the first plate 34 and the second plate 35. The first plate 34 and the second plate 35, the first plate 34 and the longitudinal beam 312, and the second plate 35 and the longitudinal beam 312 are all connected by welding. In other embodiments, the first plate 34 and the second plate 35 are integrally formed.

[0047] like Figure 1 , Figure 3 and Figure 6As shown, in some embodiments, the walking assembly 2 includes a driving member 21, a driving wheel 22, and a driven wheel 23, with the driving wheel 22 and driven wheel 23 disposed on opposite sides of the vehicle body 1. The driving wheel 22 is rotatably connected to the vehicle body 1 via a driving bearing 25 and a driving shaft 26, while the driven wheel 23 is rotatably connected to the vehicle body 1 via a driven bearing 27 and a driven shaft 28. Specifically, the main beam 11 connects to the support legs 13 of the driving bearing 25 and the driven bearing 27; the driving shaft 26 and the driven shaft 28 are rotatably connected to the driving bearing 25 and the driven bearing 27, respectively, while the driving wheel 22 and the driven wheel 23 are respectively connected to the driving shaft 26 and the driven shaft 28. The driving shaft 26 is also correspondingly connected to the driving member 21, which drives the driving shaft 26 to rotate, thereby driving the vehicle body 1 to move. In the current embodiment, two sets of walking components 2 are provided, thereby providing two driving wheels 22 and two driven wheels 23. Taking the movement of the vehicle body 1 along the second direction as an example, the two sets of walking components 2 are provided at both ends of the vehicle body 1 along the first direction, and the driving wheels 22 and driven wheels 23 in the same set are provided at both ends of the vehicle body 1 along the second direction. Exemplarily, the driving wheels 22 and driven wheels 23 can be, but are not limited to, flat wheels, which can be used in conjunction with external ground rails; the driving component 21 can be, but is not limited to, a motor.

[0048] In the current embodiment, when the number of rotations of the two driven wheels 23 is inconsistent, the vehicle body 1 slips. To minimize this phenomenon and further improve safety, an encoder 24 is connected to each driven wheel 23. The encoder 24 is connected to the drive component 21 via a control system signal, thereby identifying the number of rotations of the driven wheels 23. When the number of rotations of the two driven wheels 23 is inconsistent, the encoder 24 can adjust the rotation speed of the drive wheel 22, thereby causing the number of rotations of the two driven wheels 23 to tend to be consistent, minimizing slippage. In the current embodiment, the encoder 24 can be connected to the driven wheel 23 indirectly via, but is not limited to, an encoder coupling (not shown in the figure).

[0049] like Figure 1 and Figure 4As shown, in some embodiments, two sets of light curtain components 4 are also provided. Both sets of light curtain components 4 are connected to the drive unit 21 through the control system, and the two sets of light curtain components 4 are arranged on opposite sides of the vehicle body 1. In the current embodiment, taking the movement of the vehicle body 1 along the second direction as an example, the two sets of light curtain components 4 are arranged on opposite sides of the vehicle body 1 along the second direction, thereby forming a light curtain at both ends of the vehicle body 1 in the second direction. This allows for the identification of people or objects during the movement of the vehicle body 1 along the second direction, timely control of the start and stop of the drive unit 21, and ensures safety. Specifically, light curtain supports 7 are provided on the vehicle body 1. The two sets of light curtain supports 7 are respectively arranged at both ends of the vehicle body 1 along the first direction, and the light curtain supports 7 extend out of the vehicle body 1 along the second direction. The generator 41 and receiver 42 in the light curtain components 4 are respectively displaced to the same side of the vehicle body 1 and are arranged on the two light curtain supports 7, thereby forming a light curtain.
