Description

Technical Field

[0001] The present invention relates to the technical field of road protection tools, and particularly relates to an anti-collision buffer vehicle with a flip-up anti-collision device. Background Art

[0002] The anti-collision buffer vehicle is one of the important tools used in road protection, and is used to reduce the risk to personnel during road protection. The structure of the anti-collision buffer vehicle includes a moving vehicle body and an anti-collision device. The anti-collision device is installed at the rear end of the moving vehicle body and can be flipped up and down relative to the moving vehicle body by the movement of an oil cylinder installed on the moving vehicle body. During use, the oil cylinder drives the protection device to flip to a horizontal state. When a vehicle hits the buffer vehicle from behind, the anti-collision device provides buffering for the moving vehicle body, reducing the harm to construction workers.

[0003] Chinese Patent Document CN110761216A discloses a heavy-duty anti-collision buffer vehicle, which includes a carrying truck, a truck-mounted crane, a sub-frame assembly, a flip drive mechanism, a folding lamp bracket assembly, and a folding buffer block assembly. The truck-mounted crane is arranged on the sub-frame assembly behind the cab and in front of the carriage of the carrying truck. The folding lamp bracket assembly is arranged at the rearmost side of the carriage of the carrying truck, and the folding buffer block assembly is located behind the folding lamp bracket assembly. The lower end of the folding lamp bracket assembly is arranged on the sub-frame assembly through a connecting base; this invention uses a method of arranging a primary buffer block assembly and a secondary buffer block assembly side by side in the front and back for series connection, with a long buffering distance and good anti-collision effect. The setting of the truck-mounted crane increases the functions of the anti-collision buffer vehicle, and lifting and hoisting operations can be carried out during traffic construction.

[0004] When this invention is in use, it is necessary to separately unfold and fold multiple buffer blocks, and it is not possible to simultaneously unfold and fold multiple buffer blocks in one step, making the device inconvenient to use. In addition, this buffer vehicle cannot support multiple buffer blocks, and multiple buffer blocks may fold when subjected to impact force, thus affecting the ability to absorb the impact force of the vehicle. Summary of the Invention

[0005] The main purpose of the present invention is to provide an anti-collision buffer vehicle with a flip-up anti-collision device, which can effectively solve the problems of inconvenience during device use and possible folding of multiple buffer blocks.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

On the left and right sides of the end of the installation bracket away from the engineering vehicle, two support plates are symmetrically fixed. At one end of the two support plates close to each other, connecting blocks are rotatably installed. At one end of the two connecting blocks away from the support plates, a mounting plate is jointly fixed. At one end of the mounting plate away from the connecting blocks, two first limiting grooves are symmetrically opened. At one end of the two support plates away from each other, limiting bolts for limiting the connecting blocks are provided. On the right side of the end of the installation bracket away from the engineering vehicle, a driving motor axially connected to the connecting block is fixed. Vertically arranged in an array at one end of the mounting plate away from the connecting blocks are a plurality of buffer devices, and a transmission device is provided at one end of the installation bracket away from the engineering vehicle.

[0008] Preferably, the buffer device includes a plurality of return springs. At one end of the plurality of return springs away from the mounting plate, a buffer plate is jointly fixed. At one end of the buffer plate close to the mounting plate, two second limiting grooves adapted to the first limiting grooves are symmetrically opened. Inside the cavity of the second limiting groove, a connecting rod is provided. At one end of the buffer plate in the clockwise direction, a first support frame is fixed. At the right end of the first support frame, a support rod is rotatably installed. At the left end of the first support frame, a double-groove pulley axially connected to the support rod is rotatably installed. At one end of the buffer plate in the clockwise direction, a first tensioner is also fixed. At one end of the buffer plate away from the mounting plate, two third limiting grooves adapted to the second limiting grooves are symmetrically opened.

[0009] Preferably, the connecting rod is composed of two rotatably connected rotating rods, and the two rotating rods are installed in an X shape.

[0010] Preferably, the connection relationship between the plurality of return springs adjacent to the mounting plate and the mounting plate is a fixed connection, and the remaining plurality of return springs are fixedly connected to the adjacent buffer plates. The two rotating rods adjacent to the mounting plate are movably installed in the first limiting groove, and the remaining plurality of rotating rods are movably installed in the adjacent third limiting grooves.

[0011] Preferably, the first tensioner is connected to the double-groove pulley and the adjacent double-groove pulley through a first belt.

[0012] Preferably, when the plurality of return springs are in a natural state, the support rod is parallel to the buffer plate, and the support rod is perpendicular to the ground;

[0013] When the plurality of return springs are in a compressed state, the support rod is perpendicular to the buffer plate, and the support rod is perpendicular to the ground.

[0014] Preferably, the transmission device includes a first gear set rotatably connected to the left support plate. Fixed gears are fixed to one end of each of the two connection blocks close to each other, and the rotational connection of the fixed gear and the connection block is coaxial. At the end of the mounting bracket away from the engineering vehicle, two second support frames are symmetrically fixed. At one end of each of the two second support frames close to each other, a second gear set adapted to the fixed gear is provided. The second gear set is jointly composed of two mutually meshing gear two. A wire winding reel is jointly fixed between the two gear two not connected to the fixed gear.

[0015] Preferably, the first gear set is jointly composed of two mutually meshing gear one, and any one of the gear one is axially connected to the connection block. A second tensioner is also fixed to the end of the mounting plate away from the connection block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The anti-collision buffer vehicle of the present invention adopts a design in which the buffer device and the transmission device cooperate with each other. When the device is in use, only the connection block needs to be rotated, and then by the mutual cooperation between the wire winding reel and the fixed gear, multiple buffer devices can be deployed. At the same time, when folding multiple buffer devices, only the connection block needs to be rotated, without the need to separately deploy or fold after flipping the device, which facilitates the operation of the device. Then, through the mutual cooperation between the multiple buffer plates and the return springs, the impact force of the vehicle can be absorbed, thus ensuring the safety of construction workers.

[0019] 2. The anti-collision buffer vehicle of the present invention adopts a design in which the support rods cooperate with the transmission device. When multiple buffer devices are deployed, multiple support rods can be driven to rotate, which facilitates the operation of the device. At the same time, while multiple support rods can increase the friction between the device and the ground, they can also support multiple buffer plates, thereby improving the absorption ability of multiple buffer plates and return springs to the impact force of the vehicle.

Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Embodiment 1

[0033] As Figures 1 - 3As shown in the figure, an anti-collision buffer vehicle with a flip-up anti-collision device includes an engineering vehicle 1. A mounting bracket 11 is fixed to the rear end of the engineering vehicle 1. The mounting bracket 11 is fixedly installed at the rear end of the rear bumper of the engineering vehicle 1 (it can be connected to the rear bumper of the engineering vehicle 1 by bolts or welding. There are various connection methods, which will not be elaborated in this invention). On the left and right sides of the end of the mounting bracket 11 far from the engineering vehicle 1, two support plates 12 are symmetrically fixed. At one end of the two support plates 12 close to each other, a connecting block 13 is rotatably installed. The two support plates 12 are used for the installation of the connecting block 13. At one end of the two connecting blocks 13 far from the support plates 12, a mounting plate 14 is jointly fixed. At one end of the mounting plate 14 far from the connecting block 13, two first limiting grooves 15 are symmetrically formed.

[0034] In addition, as Figure 2 shown, at one end of the two support plates 12 far from each other, a limiting bolt 16 for limiting the connecting block 13 is provided. As Figure 3 shown, on the right side of the end of the mounting bracket 11 far from the engineering vehicle 1, a driving motor 17 axially connected to the connecting block 13 is fixed. The driving motor 17 is used to drive the connecting block 13 to rotate, so that the device does not need to be manually flipped during use, which is convenient for the operation of the device. As Figure 1 shown, a plurality of buffer devices 2 are vertically arranged in an array at one end of the mounting plate 14 far from the connecting block 13. A transmission device 3 is provided at the end of the mounting bracket 11 far from the engineering vehicle 1. The limiting bolt 16 can make the mounting plate 14 perpendicular to the mounting bracket 11 when the engineering vehicle 1 is moving, so that the plurality of buffer devices 2 are vertically placed at the rear of the engineering vehicle 1, which can ensure that the overall vehicle length will not be affected after the mounting plate 14 is flipped, which is beneficial to safe driving.

[0035] Since the anti-collision buffer vehicle is mainly applied in the engineering field, the passenger capacity and cargo capacity of the anti-collision buffer vehicle are relatively important. Therefore, when selecting the original vehicle model for the anti-collision buffer vehicle, the passenger capacity and cargo capacity of the original vehicle model need to be considered. Since the mounting bracket is fixed at the rear end of the vehicle's rear bumper, the device can be applicable to different vehicle chassis during use. When constructing, a large number of workers need to ride, and there are also many construction equipment. Then the original vehicle model needs to consider being able to carry at least nine workers, and needs to have a rear bucket to hold construction equipment. For convenient driving, the total vehicle body length is controlled within six meters. In addition, since the construction workers are relatively tired after the construction is completed, and long-term fatigue driving is likely to cause traffic accidents, and the body of this anti-collision buffer vehicle is relatively large, it is inconvenient for the driver to operate the vehicle when driving. Therefore, intelligent driving equipment such as warning radars and vision sensors can be installed on the original vehicle model to facilitate the driver's operation, thereby improving the safety of this anti-collision buffer vehicle.

[0036] It can be seen from this that the following requirements need to be involved when the anti-collision buffer vehicle is actually used:

[0037] 1. The vehicle body length does not exceed six meters, and the number of passengers that can be accommodated is not less than nine;

[0038] 2. Buffer devices 2 can be installed on vehicle models of various brands;

[0039] 3. The vehicle has a rear bucket for convenient storage of items, and both the rear bucket and the buffer device 2 can be flipped;

[0040] 4. It is equipped with highly integrated intelligent driving equipment.

[0041] In addition, as shown in Figure 3 and Figure 4 , the buffer device 2 includes a plurality of reset springs 21. One end of the plurality of reset springs 21 away from the mounting plate 14 is commonly fixed with a buffer plate 22. The plurality of reset springs 21 are used to facilitate the reset of the buffer plate 22. Two second limit slots 23 adapted to the first limit slot 15 are symmetrically opened at one end of the buffer plate 22 close to the mounting plate 14. A connecting rod 24 is arranged in the inner cavity of the second limit slot 23. The connecting rod 24 is composed of two rotatably connected rotating rods, and the two rotating rods are installed in an X shape. The two rotating rods are movably installed in the second limit slot 23. A first support frame 25 is fixed at one end of the buffer plate 22 in the clockwise direction. A support rod 26 is rotatably installed at the right end of the first support frame 25. A double-groove pulley 27 axially connected to the support rod 26 is rotatably installed at the left end of the first support frame 25. Through the axial connection between the support rod 26 and the double-groove pulley 27, the double-groove pulley 27 can drive the support rod 26 to rotate when rotating. A first tensioner 28 is also fixed at one end of the buffer plate 22 in the clockwise direction. Two third limit slots 29 adapted to the second limit slot 23 are symmetrically opened at one end of the buffer plate 22 away from the mounting plate 14.

[0042] Furthermore, as shown in Figure 3 and Figure 7 , the connection relationship between the plurality of reset springs 21 adjacent to the mounting plate 14 and the mounting plate 14 is a fixed connection, and the remaining plurality of reset springs 21 are fixedly connected to the adjacent buffer plate 22, enabling the plurality of buffer devices 2 to cooperate with each other. By using the plurality of reset springs 21 and the buffer plate 22, the anti-collision buffer vehicle can achieve multi-stage buffering, further reducing the probability of harm to the staff during the use of the anti-collision buffer vehicle. Two rotating rods adjacent to the mounting plate 14 are movably installed in the first limit slot 15, and the remaining plurality of rotating rods are movably installed in the adjacent third limit slot 29. When the two rotating rods in the same group rotate during the use of the device, it can make the plurality of buffer plates 2 all move to the side away from the mounting plate 14, thus facilitating the use of the plurality of buffer devices 2.

[0043] Further, when multiple buffer plates 22 all move towards the side away from the mounting plate 14, multiple support rods 26 can all rotate. As Figure 3 shown, the first tensioner 28 is connected to the double-groove pulley 27 and adjacent double-groove pulleys 27 through the first belt. Since the distance between adjacent buffer plates 22 changes when multiple buffer plates 22 all move towards the side away from the mounting plate 14, multiple first tensioners 28 are required to keep the first belt in a taut state, facilitating the operation of the device. Moreover, the first tensioner 28 is a prior art, and its installation method and control method are both conventional designs in the prior art, so they will not be elaborated in this invention.

[0044] In addition, when the anti-collision buffer vehicle is in use, multiple support rods 26 can support the buffer plates 22, increasing the resistance between the anti-collision buffer vehicle and the ground, and further improving the safety effect when the anti-collision buffer vehicle is in use. As Figure 7 and Figure 10 shown, when multiple return springs 21 are in a natural state, the support rod 26 and the buffer plate 22 are parallel to each other, and the support rod 26 is perpendicular to the ground. When multiple support rods 26 contact the ground, the resistance between the buffer plate 22 and the ground can be increased, enabling multiple buffer plates 22 to better absorb the impact force when the anti-collision buffer vehicle is in use. If the buffer plates 22 are directly placed on the ground, the friction between the buffer plates 22 and the ground will increase, and multiple buffer plates 22 and the return springs 21 cannot play a good energy absorption role, and it is very likely to push the engineering vehicle 1 forward, thus causing harm to the construction workers working in front of the engineering vehicle 1. As Figure 5 shown, when multiple return springs 21 are in a compressed state, the support rod 26 and the buffer plate 22 are perpendicular to each other, and the support rod 26 is perpendicular to the ground, enabling the anti-collision buffer vehicle not to increase the body length when moving, thus not affecting safe driving.

[0045] The specific implementation mode of this embodiment is: when this anti-collision buffer vehicle is driving, the connecting block 13 and the mounting bracket 11 are perpendicular to each other, enabling multiple buffer devices 2 to be vertically placed at the rear of the engineering vehicle 1, and enabling the mounting plate 14 not to affect the overall vehicle length after flipping, which is beneficial to safe driving;

[0046] When this anti-collision buffer vehicle is in use, the vehicle needs to be parked at the rear of the construction site first. Then, the limit bolt 16 is taken out and the drive motor 17 is started, so that the connecting block 13 rotates from the vertical state to the horizontal state. When the connecting block 13 rotates, through the transmission device 3, multiple buffer plates 22 can move to the side away from the mounting plate 14. At the same time, through the transmission device 3, the double-groove pulley 27 rotates, further making multiple support rods 26 contact the ground, increasing the friction between the buffer plate 22 and the ground. Then, the construction workers carry out construction at the front of the engineering vehicle 1. If a traffic accident occurs, the vehicle will hit the buffer plate 22. Due to the mutual cooperation between the multiple buffer plates 22 and the return spring 21, the impact force of the vehicle is absorbed to ensure the safety of the construction workers.

[0047] Embodiment 2

[0048] In this embodiment, on the basis of Embodiment 1, the transmission device 3 is further improved, so that when the connecting block 13 rotates, multiple buffer plates 22 can all move to the side away from the mounting plate 14, thus facilitating the absorption of the impact force.

[0049] As Figure 5 and Figure 6 shown, the transmission device 3 includes a first gear set 31 rotatably connected to the left support plate 12. Fixed gears 32 are fixed to the mutually approaching ends of the two connecting blocks 13, and the rotational connection of the fixed gears 32 and the connecting blocks 13 is coaxial. Symmetrically fixed to the end of the mounting bracket 11 away from the engineering vehicle 1 are two second support frames 33. Second gear sets 34 adapted to the fixed gears 32 are provided at the mutually approaching ends of the two second support frames 33. The second gear sets 34 are each composed of two meshing gears II. A wire winding reel 35 is commonly fixed between the two gears II not connected to the fixed gears 32. Through the connection between the fixed gears 32 and the second gear sets 34, when the connecting block 13 rotates, it can drive the two gears II to rotate, and further make the wire winding reel 35 rotate.

[0050] In addition, as Figure 5As shown in the figure, the first gear set 31 is composed of two meshing gears one, and any one of the gears one is axially connected to the connecting block 13. A second tensioner 36 is also fixed to the end of the mounting plate 14 away from the connecting block 13. The gear one not axially connected to the connecting block 13 is connected to the second tensioner 36 and the double-groove pulley 27 on the side close to the mounting plate 14 by a second belt. When the connecting block 13 rotates, it can drive the double-groove pulley 27 to rotate. Since the connecting block 13 drives the gear one axially connected to the connecting block 13 to rotate when rotating, and at the same time, it also makes the mounting plate 14 rotate around the rotation axis of the connecting block 13. If only one gear is designed, the double-groove pulley 27 will not rotate. Therefore, two meshing gears one are needed to further make the double-groove pulley 27 rotate in the reverse direction, making the device more stable during use.

[0051] Further, to enable multiple buffer plates 22 to move away from the mounting plate 14 when the connecting block 13 rotates, as Figure 8 and Figure 9 shown, a connecting line is wound around the outer surface of the wire reel 35. Through grooves are provided at the ends of multiple buffer plates 22 away from the mounting plate 14. The end of the connecting line away from the wire reel 35 is fixedly connected to the buffer plate 22 farthest from the mounting plate 14. When the wire reel 35 rotates, the buffer plate 22 farthest from the mounting plate 14 can move closer to or away from the mounting plate 14. At the same time, due to the design of multiple return springs 21, multiple buffer plates 22 can move closer to or away from the mounting plate 14 simultaneously, thus completing the retraction and extension of multiple buffer devices 2.

[0052] The specific implementation method of this embodiment is as follows: When it is necessary to deploy multiple buffer devices 2, rotating the connecting block 13 can change the mounting plate 14 from a vertical state to a horizontal state. At the same time, through the cooperation design of the fixed gear 32 and the gear two, the wire reel 35 can be rotated. Due to the characteristics of the return spring 21, multiple buffer plates 22 move away from the mounting plate 14 simultaneously, and multiple buffer devices 2 can be deployed;

[0053] At the same time, when the connecting block 13 rotates, through the cooperation design of the gear one and the double-groove pulley 27, the double-groove pulley 27 can be rotated, and further, multiple support rods 26 can also be rotated, so that multiple support rods 26 support on the ground.

[0054] It should be noted that the specific installation methods, circuit connection methods, and control methods of the drive motor 17, tensioner, connecting rod 24, etc. in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0055] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
