Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete unloading, in particular to a unloading control device for a concrete pump truck. Background Art
[0002] The unloading device of a concrete pump truck is a hopper structure installed below the discharge port of the mixing drum of the pump truck, which is used to receive and dump the mixed concrete.
[0003] In the related art, the unloading device of the concrete pump truck is mostly provided with a fixed hopper. When unloading, the bucket of the transfer vehicle is moved to the bottom of the hopper to receive the poured concrete.
[0004] However, this method still has some problems in actual use. For example, when using transfer vehicles to transfer concrete in a mixing drum, the transfer vehicles are usually required to queue up and stop at the loading position in turn. After the front vehicle is fully loaded, it is pushed out of the loading position, and then the rear vehicle is pushed under the hopper to continue loading. On the one hand, this method is inefficient and requires the pumping system of the pump truck to start and stop multiple times in coordination with the docking of the transfer vehicle. On the other hand, after the front vehicle leaves fully loaded, due to the untimely shutdown of the pumping system and the presence of residual material in the hopper, concrete will continue to be discharged and drip on the ground before the rear vehicle stops at the loading position, causing waste.
[0005] In addition, due to the fixed setting of the hopper, it is impossible to adapt to the height of the bucket of the transfer vehicle (for example, the bucket of the wheelbarrow on the construction site is generally low, and the bucket of the electric or oil-driven transfer vehicle has a stronger carrying capacity but usually has a higher bucket due to the occupancy of the chassis). As the mixed concrete is poured out, the buckets of different transfer vehicles may not be aligned with the hopper discharge port, causing the concrete to dump and deviate outside the bucket. Summary of the invention
[0006] The utility model aims to solve one of the technical problems in the above-mentioned technology at least to a certain extent.
[0007] To achieve the above-mentioned purpose, the first aspect of the utility model proposes a material unloading control device for a concrete pump truck, comprising: a hopper, a mounting frame, a rotating frame, a rotating device, a telescopic cylinder, a flipping device and a controller, wherein the mounting frame is fixedly arranged at the rear of the concrete pump truck; the rotating frame can be rotatably arranged on the mounting frame and is connected to the rotating device; the hopper is hingedly arranged on the rotating frame and is located below the discharging port of the mixing drum of the concrete pump truck, and the discharging end of the hopper is provided with an openable and closable cover plate; one end of the telescopic cylinder is pivotally connected to the hopper, and the other end is pivotally connected to the rotating frame; the flipping device is arranged on the hopper, and the flipping device is connected to the rotating shaft of the cover plate; the rotating device, the telescopic cylinder and the flipping device are respectively connected to the controller.

In addition, a telescopic cylinder for pushing the hopper is provided on the rotating frame, which can adapt to the buckets of transfer vehicles of different heights, thereby improving the unloading accuracy and avoiding the situation where the concrete unloading is offset.

DETAILED DESCRIPTION
[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0026] The following is a description of the concrete pump truck unloading control device according to an embodiment of the utility model in conjunction with the accompanying drawings.
[0027] like Figure 1 , Figure 2 and Figure 5 As shown, the concrete pump truck unloading control device according to the embodiment of the utility model may include a hopper 100 , a mounting frame 200 , a rotating frame 300 , a rotating device 400 , a telescopic cylinder 500 , a turning device 600 and a controller 700 .
[0028] The mounting frame 200 is fixedly arranged at the rear of the concrete pump truck.
[0029] The rotating frame 300 is rotatably disposed on the mounting frame 200 and is connected to the rotating device 400 .
[0030] It should be noted that the rotating device 400 can be disposed on the mounting frame 200 , and the rotating frame 300 can be rotated by starting the rotating device 400 .
[0031] The hopper 100 is hingedly mounted on the rotating frame 300 and is located below the discharge port of the mixing drum of the concrete pump truck to receive the concrete pumped in the mixing drum. An openable and closable cover plate 101 is provided at the discharge end of the hopper 100 .
[0032] It should be noted that the hopper 100 is a cavity structure with openings at both ends, or a receiving groove with openings at both ends and the top.
[0033] One end of the telescopic oil cylinder 500 is pivotally connected to the hopper 100 , and the other end is pivotally connected to the rotating frame 300 .
[0034] It should be noted that by controlling the telescopic cylinder 500, the angle of the hopper 100 can be adjusted, thereby achieving a height change at the discharge end of the hopper 100 to adapt to the buckets of different transport vehicles and avoid the discharge deviation caused by excessive height difference.
[0035] The turning device 600 is disposed on the hopper 100 , and the turning device 600 is connected to the rotation axis of the cover plate 101 .
[0036] It should be noted that the flipping device 600 can control the rotation of the cover plate 101. When unloading is in progress, the flipping device 600 controls the cover plate 101 to open. When unloading is stopped or the hopper 100 is rotated, the cover plate 101 can be controlled by the rotating device 400 to cover the discharge port of the hopper 100 to prevent the dripping of concrete due to the pumping system not being closed in time or the presence of residual material in the hopper 100, thereby reducing the waste of concrete.
[0037] The rotating device 400 , the telescopic cylinder 500 and the flipping device 600 are respectively connected to the controller 700 , and the relevant staff can control the rotating device 400 , the telescopic cylinder 500 and the flipping device 600 respectively through the controller 700 .
[0038] Specifically, when the relevant staff performs unloading operations on the concrete pump truck, first, the relevant staff can arrange multiple transfer vehicles to be arranged in two or more columns in sequence, and then the relevant staff controls the telescopic cylinder 500 through the controller 700, so that the telescopic cylinder 500 pushes the hopper 100 to rotate, so that the discharge end of the hopper 100 is closer to the bucket of the transport vehicle, and controls the flipping device 600 to rotate the cover plate 101 so that the cover plate 101 is opened.
[0039] Then the relevant staff pours the concrete in the mixing drum onto the hopper 100 through the pumping system, and the concrete slides along the hopper 100 into the bucket of the transfer vehicle. After the transfer vehicle is fully loaded, the relevant staff controls the flipping device 600 to close the cover 101, and controls the rotating device 400 to start, so that the rotating device 400 drives the rotating frame 300 and the hopper 100 to rotate, so as to rotate the hopper 100 to another column of transfer vehicles, and so on.
[0040] It should be noted that the pumping system does not need to be shut down during this process and can be kept open. After the transfer vehicle in the current column is fully loaded, the hopper 100 rotates to the top of the transfer vehicle in another column for unloading. At the same time, the fully loaded vehicles in the current column can leave the parking position, and the subsequent vehicles in the current column can park at the loading position for preparation, thereby further improving the unloading efficiency.
[0041] In one embodiment of the present invention, Figure 1As shown, the rotating device 400 includes a first driving motor 410 and a transmission structure 420 .
[0042] The first driving motor 410 is disposed on the mounting frame 200 , and the transmission structure 420 is connected to the output end of the first driving motor 410 of the rotating frame 300 .
[0043] To clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 2 and Figure 4 As shown, the transmission structure 420 includes a driving sprocket 421 , a driven sprocket 422 and a chain 423 .
[0044] The driving sprocket 421 is coaxially connected to the output end of the first driving motor 410 , the driven sprocket 422 is coaxially connected to the rotating shaft of the rotating frame 300 , and the chain 423 is arranged on the driving sprocket 421 and the driven sprocket 422 .
[0045] It should be noted that when the relevant staff turns on the rotating device 400 , the first driving motor 410 first drives the driving sprocket 421 to rotate, and the chain 423 can drive the driven sprocket 422 to rotate under the rotation of the driving sprocket 421 , thereby realizing the rotation of the rotating frame 300 .
[0046] In one embodiment of the present invention, Figure 4 As shown, a slide groove 201 is provided on the mounting frame 200 , and the slide groove 201 is an arc groove with the rotation axis of the rotating frame 300 as the center. A support column 301 is provided on the side of the rotating frame 300 away from the rotation axis, and the support column 301 is slidably set in the slide groove 201 .
[0047] As a possible situation, the slide groove 201 is an inverted T-shaped groove, and a limiting block is provided at the bottom of the support column 301 , and the limiting block slides along the slide groove 201 .
[0048] It should be noted that, through the limiting effect of the slide groove 201 , when the hopper 100 is subjected to force, the rotating frame 300 can be prevented from shaking, thereby improving the stability of the rotating frame 300 .
[0049] In one embodiment of the present invention, Figure 3 As shown, the flipping device 600 includes a second driving motor 610 , a driving gear 620 and a driven gear 630 .
[0050] The second driving motor 610 is installed on the hopper 100 through the fixing frame 601, the driving gear 620 is arranged at the output end of the second driving motor 610, the driven gear 630 is coaxially arranged with the rotating shaft of the cover plate 101, and the driving gear 620 and the driven gear 630 are meshed and connected.
[0051] It should be noted that when the relevant staff starts the flip device 600 , the second drive motor 610 drives the driving gear 620 to rotate, so that the driven gear 630 meshing with the driving gear 620 rotates, thereby rotating the cover plate 101 to achieve the opening and closing of the cover plate 101 .
[0052] It can be understood that when the hopper 100 rotates, the cover 101 can be controlled by the flipping device 600 to cover the discharge port of the hopper 100 to prevent the residual material in the hopper 100 from dripping onto the ground. When the concrete in the hopper 100 is poured into the bucket of the transfer vehicle, the cover 101 can be controlled to open by the flipping device 600 so that the concrete can be smoothly poured into the hopper 100.
[0053] In one embodiment of the present invention, the feeding end of the hopper 100 is connected to a receiving chamber 102 that expands upward and circumferentially, and the receiving chamber 102 is located directly below the discharge port of the mixing drum of the concrete pump truck.
[0054] It should be noted that, through the expanded receiving chamber 102 , when the hopper 100 is controlled by the telescopic cylinder 500 , the concrete in the mixing drum can be smoothly poured into the hopper 100 .
[0055] In summary, according to the concrete pump truck unloading control device of the embodiment of the utility model, the rotating device 400 can drive the rotating frame 300 and the hopper 100 to rotate. When the transfer vehicle is loaded with concrete, it can be arranged in multiple columns and rotated to unload in sequence, and there is no need to start and stop the pumping system multiple times, thereby improving the unloading efficiency of the concrete. The cover plate 101 is flipped over by cooperating with the flipping device 600, which can prevent the residual material in the hopper 100 from dripping onto the ground and causing waste. In addition, a telescopic cylinder 500 for pushing the hopper 100 is provided on the rotating frame 300, which can adapt to the buckets of transfer vehicles of different heights, improve the unloading accuracy, and avoid the occurrence of concrete unloading deviation.
