Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a four-way displacement vehicle. Background Technology

[0002] In automated material handling scenarios such as corrugated cardboard, current practices for long-stroke conveyor lines typically involve configuring two or more single- or double-shift displacement vehicles, each responsible for handling cardboard transfer tasks in a specific area.

[0013] In some embodiments, the crossbeam is detachably connected to the longitudinal beam. And / or, the diagonal beam is detachably connected to both the crossbeam and the longitudinal beam.

[0014] In some embodiments, the vehicle frame further includes a front frame and a rear frame opposite to each other along the first direction, the front frame being detachably connected to one end of the first vehicle frame and the second vehicle frame, and the rear frame being detachably connected to the other end of the first vehicle frame and the second vehicle frame.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, and bottom) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, the term "vertical" in the embodiments and claims refers to an angle of 90° between two components or a deviation of -5° to +5°, and the term "parallel" refers to an angle of 0° between two components or a deviation of -5° to +5°.

[0023] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] Reference Figure 1 As shown, the present invention provides a four-way displacement vehicle 1, including a trolley 10, a sliding contact line power supply device 12, a power taking device 13 and a guide rail 14. The trolley 10 is slidably connected to the guide rail 14, the trolley 10 is connected to the power taking device 13, and the trolley 10 is electrically connected to the sliding contact line power supply device 12 through the power taking device 13.

[0025] Reference Figure 2 , Figure 3 and Figure 8 As shown, the trolley 10 includes a frame 30 and four modular conveyors 20. The frame 30 includes a first frame 301 and a second frame 302 that are parallel to each other, and a support frame 303. The support frame 303 is vertically connected to the first frame 301 and the second frame 302, and driven wheels 401 are connected to the support frame 303.

[0026] Four modular conveyors 20 are sequentially arranged on the frame 30 along the first direction, and the four modular conveyors 20 are arranged in pairs on opposite sides of the supporting frame 303, wherein the conveying direction of each modular conveyor 20 is perpendicular to the first direction.

[0027] Specifically, the guide rail 14 is installed on the ground to support and guide the trolley 10, and the trolley 10 slides on the guide rail 14. The sliding contact line power supply device 12 has multiple mounting brackets 121 along the guide rail 14. One end of each mounting bracket 121, away from the guide rail 14, is connected to two spaced-apart sliding contact lines 122 to provide driving power to the trolley 10. The power collection device 13 includes a connecting rod 131. One end of the connecting rod 131 is connected to the headframe 31, and the other end is spaced-apart power collection claws 132 for the entire vehicle power supply and brake power supply. The two power collection claws 132 are electrically connected to the two sliding contact lines 122 respectively to provide power to the trolley 10.

[0028] Each modular conveyor 20 is an independent drive unit. Four modular conveyors 20 correspond to four workstations and can drive materials independently. The material transport by the four modular conveyors 20 does not affect each other, or they can be driven synchronously to transport large-sized materials. For example, only the first modular conveyor 20 may transport materials while the other three modular conveyors 20 stop transporting; alternatively, all four modular conveyors 20 may transport large-sized materials synchronously. The conveying direction of the modular conveyors 20 may be, for example, from the first frame 301 to the second frame 302, or from the second frame 302 to the first frame 301. The four modular conveyors 20 can be driven synchronously in the same conveying direction, or each modular conveyor 20 can have its conveying direction controlled independently.

[0029] The first frame 301 and the second frame 302 are parallel to each other and extend along a first direction. The module conveyor 20 connects the first frame 301 and the second frame 302, and the conveying direction is perpendicular to the first frame 301 and the second frame 302. The support frame 303 is located at the middle of the first frame 301 and the second frame 302 to provide effective support for the middle position of the trolley 10. The support frame 303 is perpendicularly connected to the first frame 301 and the second frame 302 respectively, and the support frame 303 is provided with driven wheels 401 to assist the front wheels 402 and the rear wheels 403 to move quickly, while providing support when the trolley 10 is conveying large-sized materials.

[0030] The trolley 10 integrates four modular conveyors 20, effectively increasing the single-transfer capacity and reducing transport frequency on long-stroke conveyor lines. The four modular conveyors 20 can transport large materials individually or simultaneously, flexibly adapting to various material transfer needs. When transporting large materials, the support frame 303 provides reliable support, ensuring transport stability. In long-stroke scenarios where conveying cycle time requirements are not high, a single four-station trolley 10 can replace two or more single / double-station trolleys, reducing equipment procurement, installation, and subsequent maintenance costs, thus lowering overall costs.

[0031] Reference Figure 3As shown, in some embodiments, the first frame 301 includes two first sub-frames 3012, and the second frame 302 includes two second sub-frames 3022. The support frame 303 includes a first connecting portion 3031, a second connecting portion 3032, and a main support beam 3033. The first connecting portion 3031 includes a first end and a second end disposed opposite to each other in a first direction, and the two first sub-frames 3012 are respectively connected to the first end and the second end of the first connecting portion 3031. The second connecting portion 3032 includes a third end and a fourth end disposed opposite to each other in a first direction, and the two second sub-frames 3022 are respectively connected to the third end and the fourth end of the second connecting portion 3032. The main support beam 3033 connects between the first connecting portion 3031 and the second connecting portion 3032.

[0032] The first frame 301 consists of two first sub-frames 3012 connected by a first connecting part 3031, extending the length of the first frame 301 in the first direction. The second frame 302 consists of two second sub-frames 3022 connected by a second connecting part 3032, extending the length of the second frame 302 in the first direction. The first connecting part 3031 and the second connecting part 3032 are then connected by a main support beam 3033, strengthening the support for the overall first frame 301 and second frame 302, ensuring the stability and reliability of the material transfer process. The length of each first sub-frame 3012 and second sub-frame 3022 is consistent with the length of the frame 30 of the dual-station displacement vehicle. When producing the four-station trolley 10, the existing molds of the dual-station trolley 10 can be directly reused, eliminating the need to develop new dedicated molds and significantly saving mold design and manufacturing costs. The modular combination achieves the four-station structure, simplifying the production process, reducing the customization requirements of parts, and facilitating later maintenance and component replacement.

[0033] Reference Figure 3 As shown, in some embodiments, the first connecting portion 3031 and the second connecting portion 3032 are provided with receiving cavities, and the driven wheel 401 is located in the receiving cavity. Exemplarily, the first connecting portion 3031 and the second connecting portion 3032 are rectangular, enclosing and forming a receiving cavity for accommodating the driven wheel 401, resulting in a high degree of integration of the overall frame 30 structure. The driven wheel 401 can be, for example, a rubber roller 40, composed of two wheel bodies, and located respectively within the first connecting portion 3031 and the second connecting portion 3032. During material transportation, the trolley 10 moves the driven wheel 401 via the front wheel 402 and the rear wheel 403, accelerating the movement speed of the trolley 10. Simultaneously, the addition of the driven wheel 401 further provides support for the trolley 10, evenly distributing the weight of the frame 30 and the material, and preventing overload on the front wheel 402 and the rear wheel 403.

[0034] Reference Figure 3As shown, in some embodiments, the supporting frame 303 further includes two first oblique support beams 3034, respectively disposed on opposite sides of the main support beam 3033, with each opposite end of the first oblique support beam 3034 connected to the main support beam 3033 and the first connecting portion 3031, respectively. Two second oblique support beams 3035 are also disposed on opposite sides of the main support beam 3033, with each opposite end of the second oblique support beam 3035 connected to the main support beam 3033 and the second connecting portion 3032, respectively. Exemplarily, the number of main support beams 3033 is two.

[0035] Two main support beams 3033 are connected side-by-side to improve the overall support strength connecting the first frame 301 and the second frame 302. A first diagonal support beam 3034 connects the main support beam 3033 to the first connecting part 3031, and a second diagonal support beam 3035 connects the main support beam 3033 to the second connecting part 3032. For example, two first diagonal support beams 3034 respectively connect the first main support beam 3033 to the first connecting part 3031 and the second main support beam 3033 to the first connecting part 3031. Two second diagonal support beams 3035 respectively connect the first main support beam 3033 to the second connecting part 3032 and the second main support beam 3033 to the second connecting part 3032.

[0036] The first inclined support beam 3034, the second inclined support beam 3035, the main support beam 3033, the first connecting part 3031, and the second connecting part 3032 together constitute a stable support structure, which can significantly enhance the overall rigidity of the support frame 303, effectively resist the impact and vibration during material transfer, and prevent the first connecting part 3031, the second connecting part 3032, the first sub-frame 3012, and the second sub-frame 3022 from falling off during transportation. Furthermore, the design of the first inclined support beam 3034 and the second inclined support beam 3035 avoids problems such as deformation of the first connecting part 3031 and the second connecting part 3032 and bending of the main support beam 3033 caused by long-term load-bearing or long-stroke movement, effectively extending the service life of the frame 30.

[0037] Reference Figure 3 As shown, in some embodiments, the vehicle frame 30 further includes a front frame 31 and a rear frame 32 opposite to each other in a first direction, the front frame 31 and the rear frame 32 being connected to the first vehicle frame 301 and the second vehicle frame 302, respectively.

[0038] A first subframe 3012, located between the main support beam 3033 and the cab frame 31, is detachably connected to the first end of the first connecting portion 3031. A second subframe 3022, located between the main support beam 3033 and the cab frame 31, is detachably connected to the third end of the second connecting portion 3032. And / or, The first sub-frame 3012, located between the main support beam 3033 and the rear frame 32, is detachably connected to the second end of the first connecting part 3031, and the second sub-frame 3022, located between the main support beam 3033 and the rear frame 32, is detachably connected to the fourth end of the second connecting part 3032.

[0039] For example, each subframe has a connecting steel plate at one end where it connects to the support frame 303. The connecting steel plate is fixedly connected to the first connecting part 3031 and the second connecting part 3032 by bolts. The detachable connection between the subframe and the connecting part allows the frame 30 to be flexibly disassembled and reassembled during transportation. It can either fix the support frame 303 to the two subframes near the front or rear frame 32 for semi-assembled transportation, or completely disassemble all components individually for transportation as loose parts. Multiple transportation modes can be flexibly selected according to the space size and load limit of the transportation vehicle, avoiding transportation restrictions caused by the overall frame 30 being too large or structurally complex.

[0040] Reference Figure 3 As shown, in some embodiments, each first subframe 3012 and each second subframe 3022 includes a longitudinal beam 304, a crossbeam 305, and a diagonal beam 306. The longitudinal beam 304 includes a first longitudinal beam 3041 and a second longitudinal beam 3042 that are parallel to each other. There are multiple crossbeams 305, which are spaced apart along a first direction and perpendicularly connected to the first longitudinal beam 3041 and the second longitudinal beam 3042. There are multiple diagonal beams 306, where two adjacent crossbeams 305, the first longitudinal beam 3041, and the second longitudinal beam 3042 enclose a rectangular area, and the diagonal beams 306 connect opposite corners of the rectangular area.

[0041] For example, the inclination direction of the diagonal beam 306 can be uniform, for instance, connecting the upper left corner to the lower right corner of the rectangular area. Each subframe is based on the parallel first longitudinal beam 3041 and second longitudinal beam 3042, and is equipped with multiple crossbeams 305 spaced apart along the first direction to form a grid-like frame. The overall structure is highly rigid and can effectively resist longitudinal tension and lateral impact during long-distance transportation. At the same time, diagonal beams 306 are added to the rectangular area enclosed by adjacent crossbeams 305 and longitudinal beams 304 to form a triangular stable structure, which can prevent the rectangular frame from twisting and deforming under stress, and greatly improve the torsional and bending resistance of the subframe.

[0042] Reference Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the modular conveyor 20 is detachably connected to the first frame 301 and the second frame 302. Specifically, it is connected to the longitudinal beam 304 of each sub-frame. Each modular conveyor 20 includes a track 201 and a mounting frame 202, with the mounting frame 202 located on opposite sides of the track 201 and perpendicular to the conveying direction of the track 201. The mounting frame 202 has multiple first mounting holes 2021, and each longitudinal beam 304 of the sub-frame also has corresponding second mounting holes 3043. The modular conveyor 20 is fixed to the longitudinal beam 304 by screws passing through the first mounting holes 2021 and the second mounting holes 3043.

[0043] Reference Figure 3 As shown, in some embodiments, the crossbeam 305 is detachably connected to the longitudinal beam 304. And / or, the diagonal beam 306 is detachably connected to the crossbeam 305 and the longitudinal beam 304. During the transportation stage, the crossbeam 305, longitudinal beam 304, and diagonal beam 306 can be disassembled and packaged separately, reducing transportation volume, improving space utilization, and lowering logistics costs. Furthermore, during the production stage, each component can be processed separately and inspected individually, improving manufacturing efficiency and product qualification rate.

[0044] Reference Figure 3 and Figure 8 As shown, in some embodiments, the vehicle frame 30 further includes a front frame 31 and a rear frame 32 opposite to each other in a first direction. The front frame 31 is detachably connected to one end of the first vehicle frame 301 and the second vehicle frame 302, and the rear frame 32 is detachably connected to the other end of the first vehicle frame 301 and the second vehicle frame 302.

[0045] Reference Figure 2 As shown, one end of the first frame 301 and the second frame 302 are connected to the front frame 31, and the other end is connected to the rear frame 32. The front frame 31 is equipped with a fence 311, a safety guardrail 312, and a head guardrail 313, forming an enclosed operating area to provide a safe operating space for the operator. The connecting rod 131 of the power supply device 13 is vertically connected to the front frame 31. Exemplarily, both the ends of the first frame 301 and the second frame 302 are provided with connecting steel plates, which are fixedly connected to the front frame 31 and the rear frame 32 by bolts.

[0046] During transportation, the front frame 31, rear frame 32, first frame 301, and second frame 302 can be completely disassembled, significantly reducing packaging volume, avoiding transportation limitations caused by the overall frame exceeding size limits, increasing the loading capacity of a single shipment, and reducing logistics costs. Secondly, during the assembly stage, each component can be transported independently to the site for assembly, eliminating the need for large hoisting equipment to assist in overall installation, simplifying the assembly process, and reducing on-site construction difficulty and labor costs.

[0047] Reference Figure 3As shown, in some embodiments, the vehicle 10 further includes a front wheel 402 and a rear wheel 403. The front wheel 402 is disposed within the front frame 31, and the rear wheel 403 is disposed within the rear frame 32. The vehicle 10 also includes a front drive unit 411 and a rear drive unit 412. The front drive unit 411 is disposed within the front frame 31 and electrically connected to the front wheel 402, and the rear drive unit 412 is disposed within the rear frame 32 and electrically connected to the rear wheel 403.

[0048] The front wheel 402 and rear wheel 403 can be, for example, rubber rollers 40. The front wheel 402 consists of a left front wheel 402 and a right front wheel 402, and the rear wheel 403 consists of a left rear wheel 403 and a right rear wheel 403. The front wheel 402 is located within the front frame 31, with the left and right front wheels 402 located at opposite ends. For example, the right front wheel 402 is on the same horizontal line as the first frame 301, and the left front wheel 402 is on the same horizontal line as the second frame 302. The rear wheel 403 is located within the rear frame 32, with the left and right rear wheels 403 located at opposite ends. For example, the right rear wheel 403 is on the same horizontal line as the first frame 301, and the left rear wheel 403 is on the same horizontal line as the second frame 302.

[0049] The drive unit 41 includes a front drive unit 411 and a rear drive unit 412. The front drive unit 411, which drives the front wheels 402, consists of two drive motors 413 located in the front frame 31 and electrically connected to the left and right front wheels 402 respectively. The rear drive unit 412, which drives the rear wheels 403, consists of two drive motors 413 located in the rear frame 32 and electrically connected to the left and right rear wheels 403 respectively. This four-wheel drive structure significantly increases the driving torque, effectively improving the travel speed of the vehicle 10.

[0050] Reference Figure 1 and Figure 7 As shown, in some embodiments, the power-taking device 13 includes a connecting rod 131, a power-taking claw 132, and a protective cover 133. The connecting rod 131 is connected to the trolley 10, the power-taking claw 132 is connected to the end of the connecting rod 131 away from the trolley 10, and the protective cover 133 is disposed outside the power-taking claw 132. The power-taking claw 132 may include, for example, a power-taking claw 132 for the entire vehicle power supply of the trolley 10 and a power-taking claw 132 for the brake power supply, and the protective cover 133 is sleeved on the two power-taking claws 132. When the power-taking claw 132 contacts the sliding contact line power supply device 12 to take power, a spark will be generated by the electric arc at the moment of contact. The protective cover 133 can directly block the spark from splashing outward, preventing the spark from contacting flammable materials such as cardboard transported by the trolley 10.

[0051] Reference Figure 3 and Figure 8As shown, in some embodiments, the vehicle 10 further includes an obstacle scanning device 42, which may be, for example, a radar scanning device, used to detect whether there are obstacles at the front and rear of the vehicle 10, ensuring human and machine safety. The number of obstacle scanning devices 42 may be, for example, two, with the two obstacle scanning devices 42 respectively located on the front frame 31 and the rear frame 32, and situated between the first frame 301 and the second frame 302.
