[0028] like Figure 1 and Figure 2 As shown, this utility model provides a concrete transfer device, including: a support frame 10, a transfer platform 20, a lifting transmission mechanism, a lifting drive mechanism, and a weighing sensor 50.
[0029] The support frame 10 includes a frame body 11 and left guide columns 12 and right guide columns 13 respectively connected to the left and right sides of the frame body 11. For example, the frame body 11 may have a frame structure with four vertical beams around its perimeter and multiple horizontal beams connecting the vertical beams, wherein the horizontal beams connect to the vertical beams on the same side (left and right), so that the frame body 11 has openings in the front and rear directions; the front opening allows concrete mixer trucks to pass through, and the rear opening allows workers to enter and exit for maintenance. The left guide column 12 is located between the two vertical beams on the left side, and the right guide column 13 is located between the two vertical beams on the right side. Both the left guide column 12 and the right guide column 13 extend vertically.
[0030] The transfer platform 20 includes a lifting platform 21 and a transfer hopper 22 disposed on the lifting platform 21. The lifting platform 21 is slidably connected between the left guide column 12 and the right guide column 13. Specifically, the transfer platform 20 is located in the middle of the frame structure of the entire support frame 10. The left edge of the lifting platform 21 can be slidably connected to the left guide column 12 via rollers, and the right edge of the lifting platform 21 can be slidably connected to the right guide column 13 via rollers. The entire support frame 10 is symmetrical about the left and right sides relative to the transfer platform 20. The transfer hopper 22 is used to receive, for example, leftover materials from a concrete mixer truck. The transfer hopper 22 can be a hopper with a preset volume to facilitate rapid proportioning of the concrete inside. The front of the transfer hopper 22 has a feeding port 221, and the bottom of the transfer hopper has a discharge port.
[0031] The lifting transmission mechanism includes a left transmission assembly and a right transmission assembly symmetrically arranged on the left and right sides of the transfer platform 20, respectively. The left transmission assembly includes a left lifting beam 31, a left transmission wheel 32, and a left traction member 33. The left lifting beam 31 is slidably connected to the left guide column 12 and is located above the lifting platform 21. The left transmission wheel 32 is mounted on the left lifting beam 31. The first end of the left traction member 33 is connected to the left side of the lifting platform 21, and the second end of the left traction member 33 passes around the left transmission wheel 32 and is connected to the frame 11. Similarly, the right transmission assembly includes a right lifting beam 34, a right transmission wheel 35, and a right traction member 36. The right lifting beam 34 is slidably connected to the right guide column 13. The right transmission wheel 35 is mounted on the right lifting beam 34. The first end of the right traction member 36 is connected to the right side of the lifting platform 21, and the other end of the right traction member 36 passes around the right transmission wheel 35 and is connected to the frame 11. The first end of the left traction member 33 can be connected to the bottom left side of the lifting platform 21, and the first end of the right traction member 36 can be connected to the bottom right side of the lifting platform 21 to increase the lifting stroke of the transfer platform 20.
[0032] The lifting drive mechanism includes a left hydraulic rod 41 and a right hydraulic rod 42 symmetrically arranged on the left and right sides of the transfer platform 20, respectively. The fixed end of the left hydraulic rod 41 is fixedly connected to the frame 11, and the telescopic end of the left hydraulic rod 41 is connected to the left lifting beam 31. The fixed end of the right hydraulic rod 42 is fixedly connected to the frame 11, and the telescopic end of the right hydraulic rod 42 is connected to the right lifting beam 34. The left and right lifting beams 31 and 34 are simultaneously driven to rise and fall by the symmetrically arranged left and right hydraulic rods 41 and 42. With the cooperation of the left drive wheel 32 and the left traction component 33, and the right drive wheel 35 and the right traction component 36, the lifting stroke of the lifting platform 21 can be increased, which is more labor-saving, the lifting process is more stable, and the cost is reduced.
[0033] Weighing sensors 50 are installed between the second end of the left traction member 33 and the frame 11, and between the second end of the right traction member 36 and the frame 11. For example, the weighing sensor 50 can be a tension weighing sensor, with one end connected to the frame 11 and the other end connected to the second end of the left traction member 33. The weighing sensor 50 allows for real-time and accurate measurement of the weight of the concrete in the transfer hopper 22, thus enabling precise dispensing of the remaining concrete. Furthermore, the placement of the weighing sensors 50 between the second end of the left traction member 33 and the frame 11, and between the second end of the right traction member 36 and the frame 11, saves space compared to placing them between the hopper 22 and the lifting platform 21. It also minimizes weighing errors caused by instability in the hopper 22, resulting in more accurate measurements of the concrete weight within the hopper 22.
[0034] As an example, in use, the transfer platform 20 is in its initial position, which can be the lowest position. The concrete mixer truck pours the remaining concrete into the hopper 22. The weighing sensor 50 weighs the concrete in the hopper 22. The weighing calculation system connected to the weighing sensor 50 can calculate the mass of raw materials required for mixing the concrete. Then, the required raw materials are transported into the hopper 22 to complete the mixing. The hydraulic rod drives the transfer platform 20 to move the discharge port of the hopper 22 to a preset height, such as the height of the mixer truck's inlet. The discharge port valve of the hopper 22 opens, and the mixed concrete is placed into the mixer truck, completing the mixing and transfer of the remaining materials.
[0035] Therefore, the concrete transfer device of this utility model not only has the function of transfer, but also has the functions of accurate material measurement and precise mixing. Moreover, the hydraulic drive is more stable, occupies less space, and reduces costs.
[0036] In some implementation examples, after the weighing and calculation system determines the weight of the remaining concrete, the hydraulic rod drives the discharge port of the transfer platform 20 and the transfer hopper 22 to a preset height, such as the height of the tank truck inlet. The discharge port valve of the hopper 22 opens, and the remaining concrete in the hopper 22 is placed into the tank truck and then transported to the concrete production unit, such as the mixing unit. Professional personnel can calculate the required material weight for adjusting the concrete, and the concrete production unit will then batch and add the materials to the tank truck, completing the mixing and transfer of the remaining materials. In other words, the mixing process of the remaining concrete can be carried out in the hopper 22 of this utility model's transfer device or in the mixing unit.
[0037] In some embodiments, the discharge port is located below the lifting platform 21, and a valve 222 is provided at the discharge port. The discharge port 221 may have an arc-shaped cut to facilitate the collection of remaining concrete from the discharge port of the concrete truck.
[0038] In some embodiments, two left guide columns 12 and two right guide columns 13 are provided. The two left guide columns 12 are arranged at intervals in the front-to-back direction, and the two right guide columns 13 are arranged at intervals in the front-to-back direction. Each left guide column 12 is provided with a first guide groove. The front and rear ends of the left lifting beam 31 are respectively slidably engaged with the corresponding first guide groove via first pulleys, and the left side of the lifting platform 21 near the corner is respectively slidably engaged with the corresponding first guide groove via second pulleys. Similarly, each right guide column is provided with a second guide groove. The front and rear ends of the right lifting beam 34 are respectively slidably engaged with the corresponding second guide groove via third pulleys, and the right side of the lifting platform 21 near the corner is respectively slidably engaged with the corresponding second guide groove via fourth pulleys.
[0039] Two left drive wheels 32 and two left traction components 33 are provided, and two right drive wheels 35 and two right traction components 36 are provided. The two left drive wheels 32 are fixed to the top surface of the left lifting beam 31 and are positioned near its front and rear ends. The two left traction components 33 are wound around their respective left drive wheels 32. A weighing sensor 50 is connected between the second end of each left traction component 33 and the frame 11. The two right drive wheels 35 are fixed to the top surface of the right lifting beam 34 and are positioned near its front and rear ends. The two right traction components 36 are wound around their respective right drive wheels 35. A weighing sensor 50 is connected between the second end of each right traction component 36 and the frame 11.
[0040] Furthermore, two left hydraulic rods 41 and two right hydraulic rods 42 are provided, with the two left hydraulic rods 41 located near the two left guide columns 12, and the two right hydraulic rods 42 located near the two right guide columns 13. The transfer platform 20 is driven to rise and fall more smoothly by the four symmetrical hydraulic rods, and the concrete in the hopper 22 is weighed more accurately by the four symmetrical weighing sensors 50.
[0041] In some embodiments, the left drive wheel 32 and the right drive wheel 35 are both sprockets, and the left traction member 33 and the right traction member 36 are both chains meshing with the sprockets. Alternatively, the left drive wheel 32 and the right drive wheel 35 can be pulleys, and the left traction member 33 and the right traction member 36 can be wire ropes.
[0042] In some embodiments, the bottom of the lifting platform 21 is provided with a downwardly extending left support leg 24 and a right support leg, which are respectively longer than the outlet of the transfer hopper 22. This is to support the lifting platform 21 when the hydraulic drive mechanism is stopped for maintenance.
[0043] The lifting platform 21 is also equipped with guardrails 23 around its perimeter, and a ladder 25 is also installed at the rear of the lifting platform 21. A top plate can also be installed on the top of the frame 11 to provide rain protection and protect the hopper.
[0044] In some embodiments, the concrete transfer device further includes a track 61 and guide wheels 62. The track 61 is laid on a base surface, which can be the ground or a foundation. The guide wheels 62 are installed at the bottom of the frame 11 and slide in cooperation with the track 62. Through the cooperation of the track 61 and the guide wheels 62, the concrete transfer device can move along the laying direction of the track 61.
[0045] like Figure 3 As shown, this utility model also provides a concrete transfer method, applied to the concrete transfer device of any of the above embodiments, the method comprising:
[0046] Step S11: Receiving residual concrete material through the transfer hopper 22 in its initial position. The initial position can be the lowest position of the transfer hopper 22, which facilitates receiving residual concrete material from the discharge port below the tanker truck. This initial position can be the height of the transfer platform 20 and the transfer hopper 22 when the hydraulic rod is shortened to its minimum stroke.
[0047] In step S12, the weighing sensor 50 weighs the remaining concrete in the transfer hopper 22. The weighing sensor 50 can monitor the weight of the concrete in the transfer hopper 22 in real time.
[0048] Step S13: Determine the mixing weight of the required materials based on the weighed residual concrete.
[0049] The weighing sensor 50 can be connected to a computing system to calculate the mass of raw materials required for mixing concrete. In one example, the required raw materials can be conveyed to the transfer hopper 22 for mixing. In another example, residual concrete can be discharged directly, and the required raw materials can be mixed in the mixing unit.
[0050] In step S14, the transfer platform 20 and the transfer hopper 22 are raised from their initial positions to a preset height via a lifting drive mechanism. The preset height can be slightly higher than the height of the concrete mixer truck's inlet. This preset height can be the height of the transfer platform 20 and the transfer hopper 22 when the hydraulic rod is extended to its maximum stroke.
[0051] Step S15: Open the discharge port of the transfer hopper 22 to discharge the concrete in the transfer hopper.
[0052] As described above, the mixing of residual concrete can be completed in hopper 22, and the mixed concrete can be discharged from the discharge port of transfer hopper 22 to the inlet of concrete mixer truck, thus completing the precise mixing and transfer of concrete. Alternatively, the residual concrete in hopper 22 can be discharged into the mixing unit, and the required raw materials can be mixed by the mixing unit according to the determined mixing weight.
[0053] This invention allows for adjustments to the process (flow) based on different usage scenarios. For example, when the transfer device of this invention is not required for mixing, the remaining concrete can be transferred to another tanker truck and then transported to the concrete production unit for mixing.
