Description

Technical Field

[0001] The present application relates to the technical field of engineering machinery, and in particular to a dual-purpose road engineering vehicle. Background Art

[0002] In engineering transportation, it is usually necessary to use engineering vehicles to transport tools and materials, including on the road and inside the mine. Due to the different flatness of the external road surface and the road surface inside the mine, the degree of bumps when the engineering vehicle transports materials is different, and different engineering vehicles are often required for transportation. Therefore, dual-purpose road engineering vehicles are needed to solve the above problem of replacing vehicles.

[0003] At present, general dual-purpose road engineering vehicles increase the stability of the engineering vehicle by adding tracks to increase the contact area between the tracks and the ground.

[0004] However, during the above-mentioned transportation process, when encountering deep potholes, the vehicle body itself is still prone to shaking, which makes the precision equipment and instruments on board easily collide, causing damage to the instruments and causing property losses. Summary of the invention

[0005] In order to improve the stability of the engineering vehicle, the present application provides a dual-purpose road engineering vehicle.

[0006] The present application provides a dual-purpose road engineering vehicle, which adopts the following technical solution: A dual-purpose road engineering vehicle, comprising: A vehicle body, wherein a load-bearing plate is provided on the vehicle body, and the load-bearing plate is used for placing precision instruments and equipment; The detection components are provided in two groups, and the two groups of the detection components are respectively located on both sides of the forward direction of the vehicle body, and the detection components include a detection telescopic rod, a detection wheel and a reset spring; There are two groups of adjustment components, which are respectively located on both sides of the forward direction of the vehicle body and correspond one-to-one to the two groups of detection components. The adjustment components are arranged on the vehicle body and are used to adjust the horizontality of the carrying plate; in, The detection telescopic rod is fixedly connected to the front end of the vehicle body, and the movable end is arranged in a direction close to the ground; The detection wheel is rotatably connected to the movable end of the detection telescopic rod and is tightly pressed against the ground; The reset spring is fixedly connected in the rodless cavity of the detection telescopic rod, and its two ends are respectively fixedly connected to the fixed end and the movable end of the detection telescopic rod. In the initial state, the reset spring is in a compressed state.

[0007] By adopting the above technical solution, during the transportation of the vehicle, the detection wheel abuts against the ground and rotates. When a pothole appears on the road surface in the forward direction, the detection wheel enters the pothole. Due to the height difference between the pothole and the ground, under the elastic force of the reset spring, the movable end of the detection telescopic rod drives the detection wheel to extend into the pothole, the detection wheel abuts against the pothole, and stops extending. Under the elastic force of the reset spring, the internal volume of the rodless cavity of the detection telescopic rod increases, while the internal volume of the rod cavity decreases. By detecting the volume change of the rod cavity of the telescopic rod, it is easy to judge the size of the height difference between the pothole and the ground. The detection telescopic rod transmits the height difference signal to the adjustment component, and the adjustment component adjusts the load-bearing plate in time, so that when the vehicle body tilts, the equipment is always at the same height, making it difficult for the equipment to slide, effectively preventing the equipment from colliding, and thus making it easy to protect the equipment.

[0008] Optionally, the adjustment component includes: The amplifying part includes a first telescopic rod, a second telescopic rod and a lever; An adjusting part, one end of which is connected to the vehicle body and the other end of which is connected to the carrying plate, the adjusting part being used to adjust the horizontality of the carrying plate; Wherein, the first telescopic rod and the second telescopic rod are both fixedly connected to the vehicle body and are both located below the carrying plate, the movable ends of the first telescopic rod and the second telescopic rod are arranged in the same direction, and the rodless cavity of the first telescopic rod is connected to the rod cavity of the detection telescopic rod; The two ends of the lever are rotatably connected to the movable ends of the first telescopic rod and the second telescopic rod respectively, the lever is rotatably connected to the vehicle body via a support rod, and the connection point between the support rod and the lever is arranged in a direction close to the first telescopic rod.

[0009] By adopting the above technical solution, the internal volume of the rod cavity of the detection telescopic rod is reduced. Since the rodless cavity of the first telescopic rod is connected to the rod cavity of the detection telescopic rod, the internal volume of the rodless cavity of the first telescopic rod is increased, the movable end of the first telescopic rod is extended, and the movable end of the first telescopic rod drives the lever to rotate around the connection point between the support rod and the lever. The lever squeezes the movable end of the second telescopic rod to retract, and the volume of the rodless cavity of the second telescopic rod is reduced. Since the connection point between the support rod and the lever is arranged in a direction close to the first telescopic rod, the squeezing force of the lever on the movable end of the second telescopic rod is proportionally amplified. Under the power transmission of the second telescopic rod, the power of the adjusting part is increased, thereby facilitating the adjustment of the bearing plate, thereby enhancing the stability and efficiency of the adjustment.

[0010] Optionally, the position adjustment unit includes: An elastic block is hollow inside and is fixedly connected to the vehicle body; A compression telescopic rod is fixedly connected to the vehicle body, and a movable end is arranged toward a side close to the elastic block, and the rodless cavity of the compression telescopic rod is communicated with the rodless cavity of the second telescopic rod; Two adjustable telescopic rods are provided, and the two adjustable telescopic rods are arranged along the same side of the bearing plate. The adjustable telescopic rod is fixedly connected to the vehicle body and is located below the bearing plate. The movable end of the adjustable telescopic rod is arranged in a direction close to the bearing plate and is hinged to the bearing plate. The rodless cavity of the adjustable telescopic rod is connected to the elastic block.

[0011] By adopting the above technical scheme, the lever squeezes the movable end of the second telescopic rod to retract, and the volume of the rodless cavity of the second telescopic rod is reduced; since the rodless cavity of the compressed telescopic rod is connected with the rodless cavity of the second telescopic rod, the internal volume of the rodless cavity of the compressed telescopic rod increases, the movable end of the compressed telescopic rod extends, and the elastic block is squeezed, and the internal volume of the elastic block is reduced; since the rodless cavity of the adjusting telescopic rod is connected with the elastic block, the internal volume of the rodless cavity of the adjusting telescopic rod increases, the movable end of the adjusting telescopic rod extends, and the movable end of the adjusting telescopic rod pushes one side of the supporting plate to move, thereby facilitating and timely adjusting the horizontality of the supporting plate, thereby improving the adjustment efficiency.

[0012] Optionally, a vehicle box is provided on the bearing plate, and the vehicle box is fixedly connected to the vehicle body.

[0013] By adopting the above technical solution, the car box can block falling objects from the outside, making the equipment less likely to be damaged, thereby helping to extend the service life of the equipment and making it easier to reduce costs.

[0014] Optionally, the detection telescopic rod is tilted toward the ground along the moving direction of the vehicle body.

[0015] By adopting the above technical solution, the inclined detection telescopic rod allows the detection wheel to contact the ground earlier, so that changes in the ground can be sensed earlier during the vehicle's driving process, which helps the engineering vehicle to react in advance and thus makes it easier to improve the adjustment efficiency.

[0016] Optionally, a squeezing plate is fixedly connected to the movable end of the compression telescopic rod.

[0017] By adopting the above technical solution, by increasing the contact area between the movable end of the compression telescopic rod and the elastic block, the extrusion plate can effectively disperse the pressure over a larger area, thereby facilitating the transmission of more uniform and stable power to the adjustment telescopic rod, thereby facilitating the improvement of the adjustment accuracy.

[0018] Optionally, one side of the vehicle box is open, and two opening and closing doors are hinged at the open end.

[0019] By adopting the above technical solution and adding an opening and closing door, it is easy for operators to take the equipment, thereby improving the convenience of operation.

[0020] Optionally, the detection wheel is made of wear-resistant material.

[0021] By adopting the above technical solution, the wear-resistant material has excellent wear resistance, heat resistance and chemical stability, so that the detection wheel can work for a long time in a harsh environment without being easily damaged, thereby increasing the service life of the detection wheel and reducing maintenance costs.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up the detection telescopic rod, detection wheel and reset spring, it is easy to detect the flatness of the road ahead, and then it is easy to adjust the levelness of the load-bearing plate in time; 2.
