Description

Technical Field

[0001] The utility model relates to the technical field of traffic equipment, in particular to a multifunctional construction vehicle. Background Art

[0002] When a traffic accident, road construction or traffic guidance occurs, it is necessary to place traffic cones, signs and warning lights, etc. The current traffic guidance equipment is divided into semi-automatic equipment and fully automatic guidance vehicles. Prior art 1 (CN206034326U) relates to an automatic storage device for traffic cones, which has a traffic cone storage device 3, and the traffic cones are placed on the storage device 3 in a horizontally stacked manner, but it cannot be used to store a larger number of traffic cones, and it is also difficult to accommodate high-height guidance equipment such as signs and warning lights in terms of space. Prior art 2 (CN214028375U) relates to a traffic guidance engineering vehicle, which, in order to be able to transport more traffic cones, is equipped with multiple transmission chains in the height direction of the vehicle, which is costly and very time-consuming and labor-intensive to place multiple layers of traffic cones each time. Due to the arrangement of multiple transmission chains, placing high-height traffic guidance equipment such as signboards or indicator lights in the carriage will appear very crowded, and the space inside the carriage will be obviously wasted. For example, in extreme cases, when the engineering vehicle does not need to place traffic cones but only needs to place various signboards, the space occupied by multiple transmission chains will be wasted. In addition, it is difficult to have the function of placing traffic cones, signboards and warning lights at the same time, and multiple vehicles and people are required to work together.

[0029] See also Figure 1-2 The multifunctional construction vehicle of the utility model comprises a vehicle body 1 and a vehicle compartment 4. The vehicle compartment 4 is provided with a traffic cone storage device 2, a retracting device 3, a traffic sign, and the like.

[0030] The traffic cone storage device 2 comprises a transport mechanism 21 and a bracket 22. The bracket 22 is provided with multiple layers in the vertical direction, and multiple horizontally stacked traffic cones can be placed on each layer. The transport mechanism 21 comprises a first driving motor 211, a motor sprocket 212, a mounting frame 213, a chain 214, a driving sprocket 215, a mechanism frame 216, a conveying chain 217, a plurality of conveying 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 driving motor 211 is fixed on the mounting frame 213, the driving sprocket 215 and the driven sprocket 219 are installed on the mechanism frame 216, the chain 214 is connected to the motor sprocket 212 and the driving sprocket 215, and the conveying chain 217 is connected to the driving sprocket 215 and the driven sprocket 219. The first driving motor 211 drives the chain 1 214 to rotate, the chain 1 214 drives the driving sprocket 1 215 to rotate, and the driving sprocket 1 215 drives the driven sprocket 1 219 to rotate through the conveying chain 217.

[0031] The conveyor chain 217 is provided with a plurality of conveyor plates 218 spaced apart from each other, and there is a gap between adjacent conveyor plates 218 for accommodating the base of the traffic cone. When a plurality of traffic cones are stacked horizontally, the base of the traffic cone is sequentially inserted into the gap. At the same time, a protrusion corresponding to the gap is provided at the bottom of the traffic sign, so that the traffic sign can 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 parts of the plurality of traffic cones stacked horizontally are supported by the bracket 22. Since the width of the base part is greater than the conical part, the base part extending out of the bracket is supported by the conveyor chain 217.

[0032] When it is necessary to place traffic cones, the conveyor chain 217 moves to the right under the drive of the first drive motor 211, and drives the bracket 22 and the traffic cones to move to the right at the same time. When the base of the rightmost traffic cone is located near the driven sprocket 219, the movement stops. The staff takes the traffic cone out of the bracket 22 and places it on the retracting device 3. Then the conveyor chain 217 continues to move to the right, keeping the base of the rightmost traffic cone near the driven sprocket 219. Since multiple layers of traffic cones can be placed on the bracket 22 and move with the conveyor chain 217, the staff can take out multiple traffic cones of different layers at the same time, thereby improving work efficiency; secondly, the bracket 22 moves synchronously with the conveyor chain 217, so there is no need to set up multiple conveying devices at different heights as in the prior art, which optimizes the use of the space inside the carriage 4 in the height direction. In addition, 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 218, and the traffic cones of other layers can be simply stacked on top. It is not necessary to accurately align the traffic cones of each layer with the gap between the adjacent conveyor plates 218 on the conveyor chain where the layer is located as in the prior art, thereby significantly improving work efficiency.

[0033] Furthermore, when it is necessary to deploy traffic signs, warning lights and other devices, for example Figure 1 The traffic sign shown in the figure places the traffic sign to be placed on the conveying chain 217. When the traffic sign is near the driven sprocket 219, it is convenient for the staff to remove the traffic sign. Similarly, due to the provision of the bracket 22, it is not necessary to provide multiple conveying devices at different heights. A traffic sign with a higher height can be placed in the conveying chain 217 without being hindered in the height direction, thereby having the function of simultaneously conveying traffic cones, signs and warning lights, and being able to fully utilize the space in the carriage 4.

[0034] Preferably, empty limit switches and full limit switches are provided at the front and rear ends of the transport mechanism, 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 to control the empty limit and full limit of the transport mechanism 21. It can be seen that the movement of the bracket 22 allows it to easily contact the limit switches on the transport mechanism. In the prior art, it is not possible to set switch plates on traffic cones, and manual control of the conveyor chain is required, which is very inefficient. Through the design of the bracket 22, it is easy to set a switch plate thereon to complete the automatic control of the conveyor chain.

[0035] Those skilled in the art will appreciate 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 providing the conveyor plate 218 is to slightly separate adjacent traffic cones by a certain distance to facilitate removal by staff.

[0036] When it is necessary to transport not only traffic cones but also signboards, warning lights and other devices, in addition to arranging the signboards, warning lights and traffic cones in an orderly manner along the moving direction of the conveyor chain 217, the bracket 22 can also be divided into multiple spaces along the width direction of the carriage 4 to place different devices as needed. Alternatively, multiple brackets 22 are arranged in the width direction of the carriage 4, and correspondingly, multiple conveyor chains 217 are arranged along the width direction of the carriage 4, each bracket 22 corresponds to a conveyor chain, and these conveyor chains can be controlled separately, so as to realize asynchronous transmission of different devices as needed.

[0037] See also Figure 1 , 3 -5, the folding and releasing device 3 comprises a traffic cone folding and releasing mechanism 31 and a lateral moving mechanism 32. The traffic cone folding and releasing mechanism 31 is used for collecting and releasing traffic cones, and the lateral moving mechanism 32 is used for controlling the placement shape of traffic cones.

[0038] The transverse moving mechanism 32 includes a second mechanism frame 321 and a transverse moving frame 322. The second mechanism frame 321 is fixed on the vehicle body 1, and the transverse moving frame 322 can move horizontally in the width direction of the vehicle relative to the second mechanism frame 321. The traffic cone retracting and releasing mechanism 31 includes a first conveying device 311, a second conveying device 312, and a guiding device 313. The first conveying device 311 is arranged horizontally, and the first conveying device 311 and the second conveying device 312 are installed on the transverse moving frame 322. The guiding device 313 is installed at the rear of the second conveying device 312.

[0039] When placing traffic cones, the staff places the traffic cones on the first conveying device 311, and the traffic cones are placed on the ground through the first conveying device 311, the second conveying device 312 and the guide device 313 in sequence. The placement position of the traffic cones is controlled by changing the position of the transverse moving frame 322. For example, during the placing process, the transverse moving frame 322 is controlled to move horizontally, and as the vehicle moves, the traffic cones can be placed diagonally.

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

[0042] See also Figure 7-8 The second conveying device 312 includes a device frame 31205, a traffic cone transmission mechanism, casters 31208, and a telescopic rod 31212. Guide rods 31204 are provided on both sides of the device frame 31205.

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. The extension of the telescopic rod 31212 can make the device frame 31205 rotate upward around the transmission shaft 31106 and the rotating shaft 31213, and the retractable mechanism 31 is folded and retracted to facilitate transportation.

[0043] The traffic cone transmission mechanism includes a driving wheel 31201, a driven wheel 1 31202, a second conveyor belt 31203, a pressure wheel 31206, a driven wheel 2 31209, a driven wheel 3 31207, a third driving motor 31210, and a sprocket chain transmission 3 31211. The driving wheel 31201, the driven wheel 1 31202, the pressure wheel 31206, the driven wheel 2 31209, and the driven wheel 3 31207 are installed in the device frame 31205, and the second conveyor belt 31203 is mounted on the driving wheel 31201, the driven wheel 1 31202, the driven wheel 2 31209, the driven wheel 3 31207 and under the pressure wheel 31206 to form two upper and lower inclined planes. The third driving motor 31210 drives the driving wheel 31201 and the first conveyor belt 31104 through the sprocket chain transmission 3 31211. After the traffic cone is placed on the first conveying device 311, it is transported to the second conveying belt 31203 via the first conveyor belt 31104, thereby placing the traffic cone.

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

[0045] The vertical pole 31301 is connected to the device frame 31205 and arranged on both sides of the device frame 31205. The telescopic rod 1 31302 is connected to the vertical pole 31301. The gantry 31304 is mounted on the two telescopic rods 1 31302. Under the action of the telescopic rod 1 31302, the gantry 31304 can rotate around the axis 31303; the U-shaped cross bar 31308 is installed on the upper end of the gantry 31304 and can swing around the rotation axis 31309. The left and right sides of the gantry are respectively installed with telescopic rods 2 (31305, 31311), the end of the left telescopic rod 2 31305 is rotatably connected to the guide bar 31307 through the rotation axis 31306, and the end of the right telescopic rod 2 31311 is rotatably connected to the guide bar 31313 through the rotation axis 31312. The guide rod 31310 is arranged on the inner side of the gantry.

[0046] See also Figure 1-14When the vehicle is working, the telescopic rod 31212 works, driving the device frame 31205 to rotate backward, lowering the second conveying device 312, and the caster 31208 touches the ground. When it is necessary to place traffic cones, the first drive motor 211 is started to drive the conveyor chain 217 to rotate backward, and the third drive motor 31210 is turned on at the same time to drive 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 1 219, the first drive motor 211 is stopped; the staff puts several traffic cones on the first conveyor belt 31104 in sequence, passes through the second conveyor belt 31203, and is transported to the ground under the guidance of the guide rod 31204 and the guide rod 31310. Then the first drive motor 211 is started again, driving the conveyor chain 217 to rotate backward, and the staff places the next batch of traffic cones on the first conveyor belt 31104 in sequence, and repeats the above process.

[0047] When the traffic cone moves in the guide device 313, the position is further adjusted by controlling the position of the guide strip 31313. In the process of placing the traffic cone, the second drive motor 329 can be controlled as needed to adjust the position of the lateral moving frame 322 to achieve the straight line or diagonal placement of the traffic cone. When placing the traffic cone diagonally, the second drive motor 329 is controlled to drive the lateral moving frame 322 to move intermittently from the rightmost side to the left or from the leftmost side to the right. When placing the traffic cone in a straight line on the left or right, the program controls the second drive motor 329 to drive the lateral moving frame 322 to move to the leftmost side or the 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 transverse moving frame 322 and / or the second telescopic rod to place the traffic cones within the collection range of the left guide bar 31307 and the right guide bar 31313. When the traffic cones pass under the U-shaped crossbar 31308, the base of the traffic cones falls on the lower inclined plane of the second conveying device 312. The vehicle continues to reverse, and the traffic cones go up to the second conveying device 312 due to inertia. Under the guidance of the guide rods 31204 on both sides of the device frame 31205, the traffic cones are conveyed to the first conveying device 311. The operator takes the traffic cones and places them on the conveying chain 217, and intermittently drives the conveying chain 217 to rotate leftward to move the bracket leftward.

[0049] In order to control the placement distance of traffic cones, a pulse collector is installed on the transmission shaft of the vehicle body 1, and dozens of pulse signals can be collected every time the vehicle travels a certain distance. The control system performs program control according to the collected pulse signals, and through parameter setting, the traffic cone retracting and releasing mechanism 31 can release traffic cones with equal spacing. Different parameters can be preset for the spacing of traffic cones placed in an oblique line and the spacing of traffic cones placed in a straight line, and after the equal spacing of traffic cones placed in an oblique line is completed, it will automatically convert to the equal spacing of traffic cones placed in a straight line.
