Description

Technical Field

[0001] This utility model belongs to the field of concrete pouring technology, and in particular relates to a mobile pouring trolley. Background Technology

[0002] Currently, the pouring of bridge deck retaining walls and self-compacting concrete for bridge deck track slabs requires manual operation of gantry cranes to hoist hoppers and pour the concrete manually. This is time-consuming, labor-intensive, and inefficient. Furthermore, the heavy reliance on gantry cranes makes it unsuitable for pouring concrete along the length of the bridge deck, resulting in complex operations and low construction efficiency. As a result, pouring trolleys have emerged to accommodate concrete pouring; however, current pouring trolleys are large and inconvenient to operate. Additionally, the bottom outlet of the pouring hopper is fixed and cannot be adjusted.

[0003] Therefore, there is an urgent need for a simple and reasonably designed mobile pouring trolley that is compact and movable to adapt to the pouring along the length of the bridge deck. It is also equipped with a material chute that can turn vertically or horizontally to meet the pouring needs of different directions and improve its adaptability. Utility Model Content

[0066] In this embodiment, a weighing sensor is provided at the bottom of the hopper mechanism 3, which is not shown in the figure.

[0067] In this embodiment, during actual use, the active walking wheel 1-2 is installed at one end of the bottom crossbeam 1-1 via the rear wheel seat 1-21, and the passive walking wheel 1-3 is installed at the other end of the bottom crossbeam 1-1 via the front wheel seat 1-31; both the rear wheel seat 1-21 and the front wheel seat 1-31 are U-shaped wheel seats, which facilitates the installation of the walking wheel and its connection with the bottom crossbeam 1-1.

[0068] In this embodiment, in actual use, the steering shaft 1-32 is an inverted T-shaped shaft, the bottom of the steering shaft 1-32 is connected to the top of the front wheel seat 1-31, and the shaft body of the steering shaft 1-32 extends into the wheel frame bearing seat 1-33 and is rotatably connected to the wheel frame bearing seat 1-33 through a bearing.

The extension and retraction of the steering cylinder 1-4 drives the bogie 1-34, steering shaft 1-32 and front wheel seat 1-31 to swing the passive travel wheel 1-3, thereby adjusting the steering of the passive travel wheel 1-3.

[0070] In this embodiment, during actual use, the worm gear reducer 1-6 is mounted on the rear wheel seat 1-21.

[0071] In this embodiment, during actual use, an intermediate vertical rod is added between the lowest ladder 2-4 and the bottom crossbeam 1-1, and the cylinder body of the steering cylinder 1-4 is located on the inner side of the intermediate vertical rod.

[0072] In this embodiment, during actual use, when it is necessary to move the trolley, the travel motor 1-5 operates. The travel motor 1-5 drives the active sprocket 1-7 to rotate through the worm gear reducer 1-6. The rotation of the active sprocket 1-7 drives the passive sprocket 1-9 to rotate through the chain 1-8. The rotation of the passive sprocket 1-9 synchronously drives the active travel wheel 1-2 to rotate, and the passive travel wheel 1-3 rotates synchronously, thereby enabling the pouring trolley to move.

[0073] In this embodiment, during actual use, multiple reinforcing connecting rods 2-2 arranged along the height direction are provided between the diagonal brace 2-3 and the vertical support rod 2-1, and the fence 2-6 is arranged outside the pedal 2-5.

[0074] In this embodiment, during actual use, the top of the hopper 3-1 is provided with a lifting lug 3-3, the upper inner side of the top supporting frame 2-7 is provided with a hopper load-bearing base plate 2-8, and the four supporting legs of the hopper legs 3-2 are installed on the hopper load-bearing base plate 2-8.

[0075] In this embodiment, during actual use, corner plates are fixed at the four corners of the top support frame 2-7 (not shown in the figure), and the corner plates are located below the hopper load-bearing base plate 2-8. The weighing sensor is located between the corner plate and the hopper load-bearing base plate 2-8. By setting the weighing sensor, the weight of the concrete in the hopper 3-1 can be obtained, which facilitates accurate control of concrete usage and reduces waste.

[0076] In this embodiment, when in actual use, the pressure plate 1-35 is set to seal and prevent dust from the top of the steering shaft 1-32 and the top of the bogie 1-34 when the bogie 1-34 is sleeved on the steering shaft 1-32.

[0077] In this embodiment, in actual use, the ladder 2-4 is provided with ladder handrails 2-9 on its side.

[0078] In this embodiment, by setting up a ladder handrail 2-9, a ladder 2-4, a step 2-5, and a railing 2-6, construction workers can safely pass through the ladder 2-4 to reach the step 2-5, making it convenient for them to remove the hooks on the hopper 3-1; or it can be used as a maintenance platform to check the internal condition of the hopper 3-1; secondly, in case of a power outage, construction workers can stand on it to manually open and close the hopper switch.

[0079] In this embodiment, during actual use, the extension beam 3-11 is hollow inside, which facilitates the insertion of the vertical plate 3-52 in the connecting seat 3-5 and allows the vertical plate 3-52 to move along the length of the rectangular hole 3-13; in addition, a limiting rod 3-53 is provided to pass through the waist-shaped hole 3-12 to further strengthen the limiting and ensure that the connecting seat 3-5 slides accurately with the extension and retraction end of the hydraulic cylinder 3-4.

[0080] In this embodiment, during actual use, the bottom surface of the chute 4-1 is provided with reinforcing ribs 4-5, the lower end of the support rod 4-3 is threadedly connected to an upper hinge lug 4-7, the middle part of the bottom surface of the chute 4-1 is provided with a lower hinge lug 4-9, the cylinder body of the vertical swing hydraulic cylinder 4-2 is connected to the upper hinge lug 4-7, and the telescopic end of the vertical swing hydraulic cylinder 4-2 is connected to the lower hinge lug 4-9.

[0081] In this embodiment, during actual use, when opening and closing are required, the telescopic end of the hydraulic cylinder 3-4 retracts, and the telescopic end of the hydraulic cylinder 3-4 slides along the rectangular hole 3-13 and the oblong hole 3-12. The connecting seat 3-5 moves close to the rod of the hydraulic cylinder 3-4, which in turn drives the two gates 3-8 to expand outward around the hinge shaft 3-14 via the connecting rod 3-6; conversely, when the telescopic end of the hydraulic cylinder 3-4 extends, the gates 3-8 close.

[0082] Alternatively, by manually operating the rear ends of the two manual operating levers 3-7 and bringing them together, the telescopic end of the synchronously squeezed hydraulic cylinder 3-4 will retract, which in turn will drive the two gates 3-8 to expand outward around the hinge shaft 3-14 via the connecting rod 3-6, thus opening the bottom outlet of the hopper 3-1; conversely, by releasing the manual operating levers 3-7, the gates 3-8 will close.

[0083] In this embodiment, in actual use, a Y-type three-position four-way solenoid valve is connected to the oil line of the hydraulic cylinder 3-4. When the Y-type three-position four-way solenoid valve is energized, it controls the extension or retraction of the hydraulic cylinder 3-4, which can be referred to conventional methods in the art.

The pressure in the oil circuit is zero, and it can be freely operated by the manual operating lever 3-7. It can also be operated in accordance with the conventional methods in this field.

[0085] In this embodiment, the reinforcing ribs 4-5 are provided in actual use to improve the performance of the chute 4-1 and ensure that it can bear the concrete flow.

[0086] The vertical swing hydraulic cylinder 4-2 is set up so that the lower end of the chute 4-1 can swing by extending and retracting the vertical swing hydraulic cylinder 4-2. With the support rod 4-3 and the upper part of the bottom surface of the chute 4-1 hinged and limited, the swing of the lower end of the chute 4-1 will not deviate from the bottom outlet of the discharge cylinder 3-10, ensuring that the chute 4-1 can receive the bottom discharge of the discharge cylinder 3-10 when it swings.

[0087] In addition, the outer sleeve 4-6 is set so that the support rod 4-3 can be inserted through the smooth rod and can rotate around the outer sleeve 4-6. When the support rod 4-3 rotates, it will drive the material trough 4 to swing around the outer sleeve 4-6 as a whole, which can realize the swing of the material trough 4 in both the vertical and horizontal directions, thus improving the adjustment range.

[0088] like Figure 9 As shown in this embodiment, in actual use, the side of the hopper support leg 3-2 is provided with a protruding cylinder 3-21, and a connecting bolt 3-22 is screwed into the protruding cylinder 3-21. The connecting bolt 3-22 passes through the top support frame 2-7 and extends into the protruding cylinder 3-21, realizing the detachable installation of the hopper 3-1. The part of the connecting bolt 3-22 that passes through the top support frame 2-7 can be a smooth rod.

[0089] In this embodiment, during actual use, a cable reel 5 is provided on the side of the trolley frame 2 away from the pedal 2-5 to realize the winding and storage of cables.

[0090] In this embodiment, two hopper mechanisms can be equipped for easy replacement during actual use.

[0091] In specific use, the hopper 3-1 containing concrete is installed on the hopper load-bearing base plate 2-8; wherein, when the bottom of the hopper support leg 3-2 at the bottom of the hopper 3-1 is installed on the hopper load-bearing base plate 2-8, connecting bolts 3-22 are installed at two opposite corners of the top load-bearing frame 2-7.

[0092] Then, operate the walking motor 1-5 to work. The walking motor 1-5 drives the active walking wheel 1-2 to rotate, and the passive walking wheel 1-3 rotates synchronously, thereby enabling the pouring trolley to move until the trolley is moved to the required construction position.

[0093] Next, the telescopic end of the hydraulic cylinder 3-4 is retracted. The telescopic end of the hydraulic cylinder 3-4 slides along the rectangular hole 3-13 and the oblong hole 3-12. Then the connecting seat 3-5 moves close to the rod of the hydraulic cylinder 3-4. Then, the two gates 3-8 are driven to expand outward around the hinge shaft 3-14 through the connecting rod 3-6.

[0094] Adjust the vertical or horizontal rotation of the material chute 4 so that the bottom of the chute 4-1 meets the construction requirements, in order to meet the needs of pouring the bridge deck protective wall and the bridge deck track slab self-compacting concrete, and reduce the intensity of manual labor.

[0095] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model.
