[0027] Reference Figures 1 to 4 The following are embodiments of the truck-mounted crane engineering vehicle of this utility model:
[0028] A truck-mounted crane engineering vehicle includes: a frame 100, a main body 200, and a truck-mounted crane device 300.
[0029] The main body 200 of the carriage includes a carriage floor 210 and a storage box assembly 220. A frame 100 is disposed on the lower side of the carriage floor 210 and is fixedly connected to the carriage floor 210. The storage box assembly 220 is disposed on the upper left or right end of the carriage floor 210 and is fixedly connected to the carriage floor 210. The onboard crane 300 is fixedly installed on the top of the storage box assembly 220.
[0030] In practical use, the frame 100 can increase the strength of the main body 200 of the carriage so that the carriage floor 210 can bear the load, thereby transporting engineering materials and tools. The storage box assembly 220 can store and place the tools required for the project. At the same time, the storage box assembly 220 can serve as a side railing of the main body 200 of the carriage and provide installation support for the truck-mounted crane 300, so that the truck-mounted crane installed on the top of the storage box assembly 220 can be in a higher position to provide lifting support for the project next to the vehicle.
[0031] In this embodiment, there are two storage box assemblies 220, which are arranged at a left-right interval on the upper side of the carriage floor 210. The two storage box assemblies 220 are respectively located at the left and right ends of the carriage body 200. The two storage box assemblies 220 can form barriers at the left and right ends of the upper side of the carriage floor 210, thereby achieving the effect of left and right railings for the carriage. The two storage box assemblies 220 are arranged at a distance, so that a load-bearing space can be formed between them.
[0032] To facilitate the separate storage of tools, the storage box assembly 220 includes multiple boxes. Each box is equipped with an openable door, allowing for the storage or retrieval of the necessary equipment or tools for the project.
[0033] In this embodiment, the doors of the left and right storage box assemblies 220 are arranged facing opposite sides; that is, the door of the storage box assembly 220 on the left faces left, and the door of the storage box assembly 220 on the right faces right. Engineers can directly open and close the doors from under the vehicle to access tools, facilitating engineering operations.
[0034] In this embodiment, the storage box assembly 220 includes a front box 221, a rear box 222, and a middle storage box 223. The front box 221 and the rear box are respectively located at the front and rear ends of the middle storage box 223, and the front box 221, the rear box 222, and the middle storage box 223 are fixedly connected to each other.
[0035] The bottom of the intermediate storage tank 223 is higher than the bottom of the front box 221 and the rear box, so that a wheel space is formed on the lower side of the intermediate storage tank 223. When the frame 100 is connected to the vehicle body, the rear wheel can be located within the wheel space. In a further embodiment, a wheel mudguard 224 is provided on the lower side of the intermediate storage tank 223. The wheel space can provide clearance for the rear wheel, and the wheel mudguard 224 can protect the wheel, blocking mud, gravel, etc. splashed up by the wheel during driving, protecting the vehicle body and chassis 310, and reducing damage to the paint and mechanical parts from dirt.
[0036] In this embodiment, the lower ends of both the front box 221 and the rear box are lower than the floor 210 of the vehicle body. The frame 100 has a horizontal frame 110 and a vertical frame 120. The horizontal frame 110 is fixedly connected to the floor 210 of the vehicle body, and the vertical frame 120 is fixedly connected to the lower parts of the front box 221 and the rear box. The horizontal frame 110 and the vertical frame 120 of the frame 100 can be fixedly connected to both the floor 210 of the vehicle body and the storage box assembly 220, making the vehicle body structure stable. The lower ends of both the front box 221 and the rear box are lower than the floor 210 of the vehicle body, which can prevent the vehicle chassis 310 from being too high, while increasing the height and volume of the front box 221 and the rear box, thereby storing more tools and instruments.
[0037] The horizontal frame 110 includes main beams extending front and rear, and the cross-section of the main beams is trapezoidal, wider at the top and narrower at the bottom. The trapezoidal cross-section of the main beams provides high strength and stable support for the carriage floor 210.
[0038] In this embodiment, the truck-mounted crane device 300 is disposed on the upper side of the storage box assembly 220 on the right side. The truck-mounted crane device 300 includes: a chassis 310, a boom 320, a hydraulic system 330, and a control system. The chassis 310 is fixedly installed on the upper rear end of the storage box assembly 220. The boom 320 is used to lift and move heavy objects. The hydraulic system 330 provides power and controls the extension, retraction, and rotation of the boom 320 to realize lifting operations. The control system includes a joystick and an electronic control unit for precise operation of the crane.
[0039] During vehicle operation, the vehicle-mounted crane 300 is in a non-operating state, and the boom 320 extends in the front-to-back direction. A support frame 225 is provided on the upper side of the storage box assembly 220. The support frame 225 is spaced apart from the chassis 310 to allow the boom 320 to be mounted on the support frame 225, providing support and preventing the boom 320 from swaying.
[0040] In this embodiment, a rear frame 400 is provided on the rear side of the main body 200 of the carriage, and the rear frame 400 is detachably equipped with crane outriggers 430.
[0041] Specifically, the rear frame 400 is fixedly connected to the frame 100 and the floor 210 of the vehicle body. The rear frame 400 is provided with a main step 410. Handrails 420 are provided at both ends of the main step 410. A rear step 440 is provided at the rear of the main step 410. The rear steps 440 are arranged in pairs on the left and right sides of the rear end of the main step 410. A folding ladder 450 is provided under the rear step 440.
[0042] The crane outrigger 430 is located on the lower side of the main step 410, and the lower side of the main step 410 has an outrigger cavity into which the crane outrigger 430 can be inserted in the left-right direction. The crane outrigger 430 is elongated and columnar, and when not in use, it can be inserted into the outrigger cavity of the rear frame 400. When the truck-mounted crane device 300 needs to lift heavy loads, the crane outrigger 430 can be pulled out and fixed to both sides of the engineering vehicle, increasing the supporting torque of the vehicle chassis 310 and thus enhancing the stability of the vehicle body.
[0043] In this embodiment, a ladder groove is provided on the lower side of the rear step 440. The folding ladder 450 is retractably inserted into the ladder groove. The ladder groove has extending slotted holes on both the left and right sides. Connecting shafts are provided on both the left and right sides of the front end of the folding ladder 450, and these connecting shafts are rotatably fitted into the slotted holes. Positioning blocks are also provided on the left and right sides of the folding ladder 450, and a positioning part is provided at the rear end of the ladder groove. When the folding ladder 450 is pulled out rearward, allowing the connecting shafts to slide to the rear end of the slotted holes, the positioning blocks abut against the positioning part, causing the folding ladder 450 to tilt, thus facilitating access for workers to the vehicle from the rear. When the folding ladder 450 is not needed, it can be flipped horizontally and inserted into the ladder groove for storage.
