Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more specifically to a multi-functional construction vehicle. Background Technology

[0002] When traffic accidents, road construction, or traffic diversion occur, traffic cones, signs, and warning lights need to be placed. Current traffic diversion equipment is divided into semi-automatic and fully automatic diversion vehicles. Existing technology 1 (CN206034326U) relates to an automatic traffic cone storage and retrieval device, which has a traffic cone storage unit. The traffic cones are placed horizontally on the storage unit, but it cannot be used to store a large number of traffic cones, and it is also difficult to accommodate taller traffic diversion equipment such as signs and warning lights in terms of space. Existing technology 2 (CN214028375U) relates to a traffic diversion engineering vehicle, which has multiple conveyor chains set up in the vertical direction of the vehicle to transport more traffic cones. This is costly, and placing multiple layers of traffic cones each time is very time-consuming and labor-intensive. Furthermore, due to the arrangement of multiple conveyor chains, placing taller traffic diversion equipment such as signs or indicator lights inside the vehicle becomes very crowded, resulting in significant waste of space. For example, in extreme cases where the engineering vehicle does not need to place traffic cones but only various signs, the space occupied by the multiple conveyor chains is wasted. In addition, it is difficult to simultaneously place traffic cones, signs and warning lights, requiring multiple vehicles and personnel to work together. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a multi-functional construction vehicle, comprising a vehicle body and a cargo compartment. The cargo compartment is equipped with a traffic cone storage device and a retraction device. The traffic cone storage device includes a transport mechanism and a support frame. The transport mechanism includes a conveyor chain, and the support frame is fixedly connected to the conveyor chain. The support frame has multiple layers in the vertical direction, and multiple horizontally stacked traffic cones can be placed on each layer. The support frame and the conveyor chain can respectively support the conical part and the base part of the bottommost traffic cone.

[0004] Furthermore, the conveyor chain is arranged with multiple conveyor plates spaced apart from each other, and there are gaps between adjacent conveyor plates to accommodate the base of the traffic cone.

[0005] Furthermore, a traffic sign is placed inside the carriage, and the bottom of the traffic sign has a protrusion that matches the gap.

[0006] Preferably, the transport mechanism further includes a first drive motor, a motor sprocket, a mounting frame, a chain, a driving sprocket, a mechanism frame, and a driven sprocket. The mounting frame and the mechanism frame are fixedly connected to the vehicle body. The first drive motor is fixed on the mounting frame. The driving sprocket and the driven sprocket are mounted on the mechanism frame. The chain connects the motor sprocket and the driving sprocket. The conveyor chain connects the driving sprocket and the driven sprocket.

[0007] Preferably, the bracket is divided into multiple storage spaces in the width direction of the carriage, and multiple conveyor chains are arranged in the width direction of the carriage, with each conveyor chain corresponding to one storage space of the bracket.

[0008] Preferably, the traffic cone storage device includes multiple transport mechanisms and supports; each support corresponds to one transport mechanism.

[0009] Preferably, the traffic cone deployment and retrieval device includes a traffic cone deployment and retrieval mechanism and a lateral movement mechanism. The traffic cone deployment and retrieval mechanism is used to collect and deploy traffic cones. The lateral movement mechanism includes a second mechanism frame and a lateral movement frame. The second mechanism frame is fixed to the vehicle body, and the lateral movement frame can move horizontally relative to the second mechanism frame in the width direction of the vehicle body. The traffic cone deployment and retrieval mechanism includes a first conveying device, a second conveying device, and a guiding device. The first conveying device is arranged horizontally, and the first and second conveying devices are mounted on the lateral movement frame. The guiding device is mounted at the rear of the second conveying device.

[0010] Preferably, a second drive motor is installed on one side of the second mechanism frame, and a driven sprocket is installed on the other side. A driving sprocket is installed on the second drive motor, and a chain connects the driven sprocket and the driving sprocket. Slide rails and square tubes are installed on the upper and lower sides of the second mechanism frame, a grooved wheel is installed on the transverse moving frame, a chain connecting plate connects the chain and the transverse moving frame, and limit switches are installed on both sides of the second mechanism frame.

[0011] Preferably, the second conveying device includes a device frame, a traffic cone transmission mechanism, casters, and a telescopic rod. Guide rods are provided on both sides of the device frame, and the traffic cone transmission mechanism is located between the two guide rods to guide the traffic cones during transmission. The casters can contact the ground to provide rolling support for the second conveying device. One end of the telescopic rod is connected to the transverse moving frame, and the other end is connected to the device frame. When the telescopic rod extends, it allows the device frame to rotate upward around the drive shaft and the rotating shaft.

[0012] Preferably, the guide device is provided with uprights, telescopic rods, and guide rods on both sides, and the guide device also includes a gantry frame and a U-shaped crossbar;

[0013] The uprights are connected to the device frame and arranged on both sides of the device frame. The first telescopic rod is connected to the upright. The gantry frame is erected on the two first telescopic rods. Under the action of the first telescopic rod, the gantry frame can rotate relative to the upright. The two ends of the U-shaped crossbar are installed on the upper part of the gantry frame, and the U-shaped crossbar can swing relative to the upper part of the gantry frame.

[0014] The multi-functional construction vehicle of the present invention has the following technical effects: (1) Due to the support frame, it is not necessary to set up multiple conveying devices at different heights. The traffic signs with higher heights can be placed in the conveyor chain without being obstructed in the height direction, thus having the function of simultaneously conveying traffic cones, signs and warning lights, and can make full use of the space inside the carriage; (2) Switches can be easily set on the support frame, and the empty limit switches and full limit switches at the front and rear ends of the transport mechanism can complete the automatic control of the conveyor chain; (3) When preparing traffic cones, it is only necessary to align the base of the bottom layer of traffic cones with the gap on the adjacent conveyor plate, and the traffic cones of other layers can be simply stacked on top, which improves work efficiency; (4) The support frame can be expanded to divide the carriage into multiple spaces along the width direction, and different equipment can be placed as needed. Alternatively, multiple supports can be set up in the width direction of the carriage, and correspondingly, multiple conveyor chains can be set up along the width direction of the carriage, with each support frame corresponding to one conveyor chain. These conveyor chains can be controlled individually, thereby realizing the asynchronous transmission of different equipment as needed. Attached Figure Description

[0029] See Figure 1-2 The multi-functional construction vehicle of the present invention includes a vehicle body 1 and a carriage 4. The carriage 4 is equipped with a traffic cone storage device 2, a retraction device 3, and traffic signs, etc.

[0030] The traffic cone storage device 2 includes a transport mechanism 21 and a support 22. The support 22 has multiple layers in the vertical direction, and multiple horizontally stacked traffic cones can be placed on each layer. The transport mechanism 21 includes a first drive motor 211, a motor sprocket 212, a mounting frame 213, a chain 214, a drive sprocket 215, a mechanism frame 216, a conveyor chain 217, multiple conveyor plates 218, and a driven sprocket 219. The mounting frame 213 and the mechanism frame 216 are fixedly connected to the vehicle body 1. The first drive motor 211 is fixed on the mounting frame 213. The drive sprocket 215 and the driven sprocket 219 are mounted on the mechanism frame 216. The chain 214 connects the motor sprocket 212 and the drive sprocket 215. The conveyor chain 217 connects the drive sprocket 215 and the driven sprocket 219. The first drive motor 211 drives the chain 214 to rotate, the chain 214 drives the drive sprocket 215 to rotate, and the drive sprocket 215 drives the driven sprocket 219 to rotate through the conveyor chain 217.

[0031] The conveyor chain 217 is equipped with multiple conveyor plates 218 spaced apart from each other, with gaps between adjacent conveyor plates 218 to accommodate the bases of traffic cones. When multiple traffic cones are horizontally stacked, the bases of the traffic cones are inserted into the gaps sequentially. Simultaneously, a protrusion corresponding to the gap is provided at the bottom of the traffic sign, allowing the traffic sign to be placed on the conveyor chain 217. The bracket 22 is fixedly connected to the conveyor chain 217, and multiple layers of traffic cones can be placed on the bracket 22. The conical portions of the horizontally stacked traffic cones are supported by the bracket 22. Since the width of the base portion is greater than the conical portion, the base portion extending out of the bracket is supported by the conveyor chain 217.

[0032] When traffic cones need to be deployed, the conveyor chain 217 moves to the right under the drive of the first drive motor 211, simultaneously moving the support 22 and the traffic cones to the right. The movement stops when the base of the rightmost traffic cone is near the driven sprocket 219. Workers remove the traffic cones from the support 22 and place them on the take-up / take-down device 3. The conveyor chain 217 then continues to move to the right, keeping the base of the rightmost traffic cone near the driven sprocket 219. Because the support 22 can hold multiple layers of traffic cones and moves with the conveyor chain 217, workers can simultaneously remove multiple traffic cones from different layers, thus improving work efficiency. Secondly, since the support 22 moves synchronously with the conveyor chain 217, it eliminates the need for multiple conveying devices at different heights, as is required in existing technologies, optimizing the vertical utilization of the space inside the carriage 4. Furthermore, when preparing traffic cones, it is only necessary to align the base of the bottommost traffic cone with the gap on the adjacent conveyor plate 218, and then simply stack the traffic cones of other layers on top of it. Unlike existing technologies, it is not necessary to accurately align the traffic cones of each layer with the gap on the adjacent conveyor plate 218 on the conveyor chain in which that layer is located, thereby significantly improving work efficiency.

[0033] Furthermore, when it is necessary to deploy traffic signs, warning lights, or other devices, for example... Figure 1 The traffic sign shown is placed on the conveyor chain 217. When the traffic sign is near the driven sprocket 219, it is easy for staff to remove it. Similarly, because of the bracket 22, it is not necessary to set up multiple conveyor devices at different heights. Higher traffic signs can be placed on the conveyor chain 217 without being obstructed in the vertical direction, thus enabling the simultaneous transport of traffic cones, signs, and warning lights, and making full use of the space inside the carriage 4.

[0034] Preferably, the transport mechanism is equipped with empty limit switches and full limit switches at both ends, and corresponding switch plates (not shown) are provided on the bracket 22. When the bracket 22 moves, the switch plates contact the corresponding limit switches, thereby controlling the empty and full limits of the transport mechanism 21. Thus, by moving the bracket 22, it can easily contact the limit switches on the transport mechanism. In the prior art, it is impossible to install switch plates on traffic cones, requiring manual control of the conveyor chain, which is very inefficient. The design of the bracket 22 allows for easy installation of switch plates, enabling automatic control of the conveyor chain.

[0035] Those skilled in the art will understand that since the bracket is fixedly connected to the conveyor chain 217 and can move with the conveyor chain 217, the conveyor plate 218 on the conveyor chain 217 is not necessary. The main purpose of setting the conveyor plate 218 is to separate adjacent traffic cones by a certain distance, so that it is convenient for workers to take them out.

[0036] When it is necessary to transport traffic cones as well as signs, warning lights, and other devices, in addition to arranging the signs, warning lights, and traffic cones in an orderly manner along the movement direction of the conveyor chain 217, the brackets 22 can also be divided into multiple spaces along the width direction of the carriage 4 to place different equipment as needed. Alternatively, multiple brackets 22 can be set in the width direction of the carriage 4, and correspondingly, multiple conveyor chains 217 can be set along the width direction of the carriage 4, with each bracket 22 corresponding to one conveyor chain. These conveyor chains can be controlled individually to achieve asynchronous transmission of different equipment as needed.

[0037] See Figure 1 , 3 -5. The traffic cone deployment and retrieval device 3 includes a traffic cone deployment and retrieval mechanism 31 and a lateral movement mechanism 32. The traffic cone deployment and retrieval mechanism 31 is used to retrieve and deploy traffic cones, and the lateral movement mechanism 32 is used to control the placement shape of the traffic cones.

[0038] The lateral movement mechanism 32 includes a second mechanism frame 321 and a lateral movement frame 322. The second mechanism frame 321 is fixed to the vehicle body 1, and the lateral movement frame 322 can move horizontally relative to the second mechanism frame 321 in the width direction of the vehicle body. The traffic cone deployment and retraction mechanism 31 includes a first conveying device 311, a second conveying device 312, and a guide device 313. The first conveying device 311 is arranged horizontally, and the first conveying device 311 and the second conveying device 312 are mounted on the lateral movement frame 322. The guide device 313 is mounted at the rear of the second conveying device 312.

[0039] When placing traffic cones, workers place them on the first conveying device 311. The traffic cones are then placed on the ground via the first conveying device 311, the second conveying device 312, and the guide device 313. The placement of the traffic cones can be controlled by changing the position of the lateral moving frame 322. For example, the lateral moving frame 322 can be controlled to move horizontally during placement, allowing the traffic cones to be placed diagonally as vehicles move.

[0040] See Figure 4The transverse moving mechanism 32 has a second drive motor 329 mounted on one side of its frame 321, and a driven sprocket 324 mounted on the other side. A driving sprocket 328 is mounted on the second drive motor 329, and a chain 327 connects the driven sprocket 324 and the driving sprocket 328. The frame 321 has slide rails 330 and square tubes 331 mounted on its upper and lower sides. A grooved wheel 325 is mounted on the transverse moving frame 322, and a chain connecting plate 326 connects the chain 327 and the transverse moving frame 322. Limit switches 323 are mounted on both sides of the frame 321. Therefore, the transverse moving frame 322 can move horizontally relative to the frame 321 in the width direction of the carriage.

[0041] See Figure 6 The first conveying device 311 includes a drive wheel 31101, a driven wheel 31102, a device frame 31103, a first conveyor belt 31104, a first sprocket and chain drive 31105, a second sprocket and chain drive 31107, and a drive shaft 31106. The drive wheel 31101 and the driven wheel 31102 are installed inside the device frame 31103. The first conveyor belt 31104 is fitted onto the drive wheel 31101 and the driven wheel 31102. The first sprocket and chain drive 31105 rotates synchronously with the second sprocket and chain drive 31107 through the drive shaft 31106.

[0042] See Figure 7-8 The second conveying device 312 includes a device frame 31205, a traffic cone conveying mechanism, casters 31208, and a telescopic rod 31212. Guide rods 31204 are provided on both sides of the device frame 31205. The traffic cone conveying mechanism is located between the two guide rods 31204 and is used to guide the traffic cone during the conveying process. The casters 31208 can contact the ground to provide rolling support for the second conveying device 312. One end of the telescopic rod 31212 is connected to the transverse moving frame 322, and the other end is connected to the device frame 31205. When the telescopic rod 31212 extends, the device frame 31205 can rotate upward around the drive shaft 31106 and the rotating shaft 31213. The traffic cone unfolding mechanism 31 folds up for easy transportation.

[0043] The traffic cone transmission mechanism includes a drive wheel 31201, a driven wheel 31202, a second conveyor belt 31203, a pressure wheel 31206, a driven wheel 31209, a driven wheel 31207, a third drive motor 31210, and a sprocket and chain drive 31211. The drive wheel 31201, driven wheel 31202, pressure wheel 31206, driven wheel 31209, and driven wheel 31207 are mounted within a frame 31205. The second conveyor belt 31203 is fitted onto the drive wheel 31201, driven wheel 31202, driven wheel 31209, driven wheel 31207, and under the pressure wheel 31206, forming two inclined planes. The third drive motor 31210 drives the drive wheel 31201 and the first conveyor belt 31104 via the sprocket and chain drive 31211. After the traffic cone is placed on the first conveyor device 311, it is conveyed to the second conveyor belt 31203 via the first conveyor belt 31104, thereby releasing the traffic cone.

[0044] See Figure 9-11 The guide device 313 is equipped with uprights 31301, telescopic rod 1 31302, telescopic rod 2 (31305, 31311), guide rod 31310, and guide strip (31307, 31313) on both sides; it also includes a gantry frame 31304 and a U-shaped crossbar 31308.

[0045] The uprights 31301 are connected to the device frame 31205 and arranged on both sides of the device frame 31205. Telescopic rod 31302 is connected to the uprights 31301. The gantry frame 31304 is mounted on the two telescopic rods 31302. Under the action of the telescopic rods 31302, the gantry frame 31304 can rotate around the axis 31303. The U-shaped crossbar 31308 is installed on the upper end of the gantry frame 31304 and can swing around the pivot 31309. Telescopic rods 31305 and 31311 are respectively installed on the left and right sides of the gantry frame. The end of the left telescopic rod 31305 is rotatably connected to the guide bar 31307 via the pivot 31306, and the end of the right telescopic rod 31311 is rotatably connected to the guide bar 31313 via the pivot 31312. The guide bar 31310 is located on the inner side of the gantry frame.

[0046] See Figure 1-14When the work vehicle is in operation, the telescopic boom 31212 operates, driving the device frame 31205 to rotate backward, lowering the second conveyor device 312, and the casters 31208 touch the ground. When traffic cones need to be deployed, the first drive motor 211 is started, driving the conveyor chain 217 to rotate backward, and at the same time, the third drive motor 31210 is turned on, driving the first conveyor belt 31104 and the second conveyor belt 31203 to rotate synchronously. The bracket 22 moves backward with the conveyor chain 217. When the base of the rightmost traffic cone on the bracket is near the driven sprocket 219, the first drive motor 211 is stopped. The workers place several traffic cones sequentially on the first conveyor belt 31104, pass through the second conveyor belt 31203, and are guided to the ground by the guide rod 31204 and the guide rod 31310. Then the first drive motor 211 starts again, driving the conveyor chain 217 to rotate backward. The staff then place the next batch of traffic cones on the first conveyor belt 31104 in sequence, and repeat the above process.

[0047] When the traffic cone moves with the guide device 313, its position is further adjusted by controlling the position of the guide strip 31313. During the deployment of the traffic cone, the second drive motor 329 can be controlled as needed to adjust the position of the lateral moving frame 322, enabling the traffic cone to be placed in a straight line or diagonally. When deploying traffic cones diagonally, the second drive motor 329 is controlled to move the lateral moving frame 322 intermittently from the rightmost side to the left or from the leftmost side to the right. When deploying traffic cones in a straight line to the left or right, the program controls the second drive motor 329 to move the lateral moving frame 322 to the leftmost or rightmost side.

[0048] When collecting traffic cones, the vehicle reverses in a straight line, the third drive motor 31210 reverses, and the operator controls the lateral moving frame 322 and / or the telescopic rod 2 to place the traffic cone within the collection range of the left guide bar 31307 and the right guide bar 31313. When the traffic cone passes under the U-shaped crossbar 31308, the base of the traffic cone lands on the lower inclined plane of the second conveying device 312. The vehicle continues to reverse, and the traffic cone, due to inertia, moves onto the second conveying device 312. Guided by the guide rods 31204 on both sides of the device frame 31205, the traffic cone is conveyed to the first conveying device 311. The operator picks up the traffic cone and places it on the conveyor chain 217, and intermittently drives the conveyor chain 217 to rotate to the left, moving the support to the left.

[0049] To control the placement distance of traffic cones, a pulse collector is installed on the drive shaft of the vehicle body 1. Dozens of pulse signals are collected every certain distance the vehicle travels. The control system performs program control based on the collected pulse signals. Through parameter settings, the traffic cone deployment and retraction mechanism 31 can deploy traffic cones at equal intervals. Different parameters can be preset for the spacing of traffic cones deployed diagonally and linearly. After the diagonally deployed traffic cones are completed, it automatically switches to the linear deployment of equally spaced traffic cones.
