Description

Technical Field

[0001] This utility model relates to the technical field of concrete placing equipment, and in particular to a concrete transfer device. Background Technology

[0002] Currently, concrete is typically transferred to the placing boom using either a sloping-pull feeder or a transfer trolley. Using a sloping-pull feeder requires the concrete mixer truck to drive into the production plant. If a conventional transfer trolley is used, it must pick up the concrete directly from the mixing plant before transferring it to the placing boom. However, with increasing construction requirements, some projects, due to cost and environmental considerations, require concrete mixer trucks to load concrete outside the plant before transferring it to the placing boom, rendering existing equipment inadequate for these requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a concrete transfer device with a simple structure that can pick up concrete from a concrete mixer truck outside the factory and transfer it to the concrete placing boom.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A concrete transfer device includes a frame, on which a first transfer track, a lifting support, and a lifting drive mechanism for driving the lifting support to rise and fall are provided. A transfer trolley is provided on the first transfer track, and a material tank and a material tank drive mechanism for driving the material tank to rotate are provided on the transfer trolley. A second transfer track is provided on the lifting support that can be connected to the first transfer track.

[0005] As a further improvement to the above technical solution: the transfer trolley is equipped with a drive wheel set, and a power supply mechanism is provided on the first transfer track. The power supply mechanism is detachably connected to the transfer trolley. The power supply mechanism is equipped with a current collector and a cable reel. One end of the cable on the cable reel is connected to the current collector, and the other end of the cable is connected to the drive wheel set.

[0006] As a further improvement to the above technical solution: both the power supply mechanism and the drive wheel assembly are provided with cable guide wheels, and the cable is wound around the cable guide wheels.

[0007] As a further improvement to the above technical solution: the power supply mechanism is provided with a connecting part, and the transfer trolley is provided with a first hook part that is detachably connected to the connecting part.

[0008] As a further improvement to the above technical solution: the opening of the first hook portion is arranged facing upwards; As a further improvement to the above technical solution: the connecting part is a rod-shaped part, which is arranged horizontally; or, the connecting part is a second hook part, which is arranged with its opening facing downward.

[0009] As a further improvement to the above technical solution: the first transfer track is provided with a sliding contact line for supplying power to the current collector.

[0010] As a further improvement to the above technical solution: the frame is provided with a first locking mechanism for locking the power supply mechanism at one end of the first transfer track near the second transfer track.

[0011] As a further improvement to the above technical solution: the lifting bracket is provided with a second locking mechanism for locking the transfer trolley.

[0012] As a further improvement to the above technical solution: the second locking mechanism includes two or more telescopic pins, and the transfer trolley is provided with two or more insertion holes, and the insertion holes are configured in a one-to-one correspondence with the telescopic pins.

[0013] As a further improvement to the above technical solution: the frame is provided with a lifting guide rail, and the lifting bracket is provided with lifting guide wheels that move along the lifting guide rail.

[0014] Compared with the prior art, the advantages of this utility model are: The concrete transfer device disclosed in this utility model involves a transfer trolley moving a material tank along a first transfer track. After reaching the end of the first transfer track, the tank is further transferred to a second transfer track. A lifting drive mechanism lowers the lifting support, transfer trolley, and material tank as a whole. Once the material tank reaches its lowest position, a concrete mixer truck located outside the plant pours concrete into the material tank. The lifting drive mechanism then raises the entire assembly, including the material tank. When the second transfer track aligns with the first transfer track, the transfer trolley moves the material tank from the second transfer track to the first transfer track and continues along the first transfer track above the concrete placing boom. The material tank drive mechanism then rotates the material tank, pouring the concrete into the concrete placing boom. The device has a simple structure, is easy to use, and meets construction requirements.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Figures 1 to 9 This invention illustrates an embodiment of a concrete transfer device. The device includes a frame 1, on which a first transfer track 2, a lifting support 3, and a lifting drive mechanism 5 for driving the lifting support 3 to move up and down are mounted. A transfer trolley 4 is mounted on the first transfer track 2, and a material tank 41 and a material tank drive mechanism 42 for driving the material tank 41 to rotate are mounted on the transfer trolley 4. A second transfer track 31, which can connect with the first transfer track 2, is mounted on the lifting support 3. The frame 1 can be a portal frame structure for good stability. The lifting drive mechanism 5 can be, for example, a hydraulic cylinder, a screw and nut mechanism, or a sprocket and chain mechanism, as long as it can drive the lifting support 3 to move up and down. The material tank 41 can be, for example, a torpedo tank, and the material tank drive mechanism 42 can be, for example, a motor and reducer. The first transfer track 2 and the second transfer track 31 can be I-beam rails, etc. The transfer trolley 4 moves along the lower flange of the I-beam rail. Preferably, the first transfer track 2 and the second transfer track 31 are horizontally arranged.

[0030] In this embodiment of the concrete transfer device, during use, the transfer trolley 4 drives the material tank 41 to move along the first transfer track 2. After moving to the end of the first transfer track 2, it is further transferred to the second transfer track 31 (specifically as follows). Figure 2 and Figure 3 As shown), the lifting drive mechanism 5 drives the lifting support 3, the transfer trolley 4, and the material tank 41 to descend as a whole. After the material tank 41 descends to the low position (specifically as shown), Figure 4 As shown in the figure, a concrete mixer truck located outside the factory pours concrete into the material tank 41. Then, the lifting drive mechanism 5 drives the material tank 41 and the whole assembly to rise. When the second transfer track 31 rises to align with the first transfer track 2, the transfer trolley 4 drives the material tank 41 from the second transfer track 31 to the first transfer track 2, and continues to move along the first transfer track 2 to above the concrete placing boom (not shown in the figure). The material tank drive mechanism 42 drives the material tank 41 to rotate, pouring the concrete into the concrete placing boom. The structure is simple, easy to use, and can meet the construction requirements.

[0031] See details Figure 7 and Figure 8 In this embodiment, the transfer trolley 4 is equipped with a drive wheel assembly 43, and a power supply mechanism 6 is provided on the first transfer track 2. The power supply mechanism 6 is detachably connected to the transfer trolley 4. The power supply mechanism 6 is equipped with a current collector 61 and a cable reel 62. One end of the cable 64 on the cable reel 62 is connected to the current collector 61, and the other end of the cable 64 is connected to the drive wheel assembly 43. The current collector 61 supplies power to the drive wheel assembly 43 through the cable 64, enabling the drive wheel assembly 43 to drive the transfer trolley 4 to move. When the transfer trolley 4 moves along the first transfer track 2, the power supply mechanism 6 remains connected to the transfer trolley 4 and moves with the transfer trolley 4 along the first transfer track 2 until the transfer trolley 4 moves to the second transfer track 31. At this time, the power supply mechanism 6 is located at the end of the first transfer track 2. When the transfer trolley 4 descends, the power supply mechanism 6 disengages from the transfer trolley 4, and the cable reel 62 releases the cable 64, so that the current collector 61 and the drive wheel assembly 43 remain electrically connected. The structure is reasonable and effective.

[0032] In a preferred embodiment, both the power supply mechanism 6 and the drive wheel assembly 43 are provided with cable guide wheels 7, and the cable 64 is wound around the cable guide wheels 7, so that the cable 64 can be smoothly wound and unwound, avoiding tangling.

[0033] Furthermore, in this embodiment, the power supply mechanism 6 is provided with a connecting part 65, and the transfer trolley 4 is provided with a first hook part 44 that is detachably connected to the connecting part 65. See details. Figure 9 When the transfer trolley 4 moves along the first transfer track 2, the first hook portion 44 drives the connecting portion 65 to move, thereby enabling the power supply mechanism 6 to move along the first transfer track 2. When the transfer trolley 4 descends, the first hook portion 44 disengages from the connecting portion 65, resulting in a reasonable and effective structure. Preferably, the power supply mechanism 6 is positioned close to the drive wheel assembly 43, and correspondingly, the first hook portion 44 is located on the drive wheel assembly 43, facilitating a detachable connection and electrical conduction between the power supply mechanism 6 and the drive wheel assembly 43.

[0034] In this embodiment, the first hook portion 44 is arranged with its opening facing upwards, and the connecting portion 65 is a rod-shaped portion arranged horizontally. When the first hook portion 44 is connected to the rod-shaped portion, the rod-shaped portion can be pushed or pulled, thereby realizing the movement of the power supply mechanism 6 along the first transfer track 2. When the first hook portion 44 descends, it can automatically separate from the rod-shaped portion; conversely, when the first hook portion 44 rises, it can reconnect with the rod-shaped portion. The structure is simple and easy to use.

[0035] In other embodiments, the connecting part 65 is a second hook part with its opening facing downwards. When the first hook part 44 and the second hook part are connected, the second hook part can also be pushed or pulled, thereby enabling the power supply mechanism 6 to move along the first transfer track 2. When the first hook part 44 descends, it can automatically separate from the second hook part; conversely, when the first hook part 44 rises, it can reconnect with the second hook part. The structure is simple and easy to use.

[0036] In a preferred embodiment, the first transfer track 2 is provided with a sliding contact line (not shown in the figure) on its side for supplying power to the current collector 61. When the current collector 61 moves along the first transfer track 2, it obtains power through sliding contact with the sliding contact line; this technology is mature and reliable. Of course, in other embodiments, the current collector 61 can also obtain power in other ways, which will not be elaborated further.

[0037] See details Figure 3 Furthermore, in this embodiment, the frame 1 is provided with a first locking mechanism 81 for locking the power supply mechanism 6 at one end of the first transfer track 2 near the second transfer track 31. When the power supply mechanism 6 moves to the end of the first transfer track 2, the first locking mechanism 81 locks the power supply mechanism 6 to prevent the power supply mechanism 6 from moving accidentally, causing it to fall off the first transfer track 2 or preventing the connection between the connecting part 65 and the first hook part 44 from being restored.

[0038] See details Figure 5 and Figure 6 In this embodiment, the lifting bracket 3 is provided with a second locking mechanism 82 for locking the transfer trolley 4. After the transfer trolley 4 moves to the second transfer track 31, the second locking mechanism 82 locks the transfer trolley 4, preventing the transfer trolley 4 from moving unexpectedly during the lifting process and improving the reliability of the equipment.

[0039] In a preferred embodiment, the second locking mechanism 82 includes two or more telescopic pins (e.g., driven by cylinders, hydraulic cylinders, etc.), and the transfer trolley 4 is provided with two or more insertion holes 45, with each insertion hole 45 corresponding to a telescopic pin. After the transfer trolley 4 moves to the second transfer track 31, each telescopic pin extends and inserts into the corresponding insertion hole 45, thereby locking the transfer trolley 4 to the lifting bracket 3 and preventing accidental movement during lifting. When the transfer trolley 4 needs to move from the second transfer track 31 to the first transfer track 2, the telescopic pins retract and disengage from the insertion holes 45. The structure is simple and reliable. Of course, in other embodiments, the second locking mechanism 82 can also be a telescopic friction plate, which increases frictional resistance to prevent accidental movement of the transfer trolley 4 during lifting, or the second locking mechanism 82 can also be an electromagnet, which generates magnetic attraction after conduction to prevent accidental movement of the transfer trolley 4 during lifting. The structure of the first locking mechanism 81 can be the same as that of the second locking mechanism 82, and will not be described again.

[0040] See details Figure 5 In this embodiment, the frame 1 is provided with a lifting guide rail 11, and the lifting support 3 is provided with a lifting guide wheel 32 that moves along the lifting guide rail 11. The lifting guide rail 11 and the lifting guide wheel 32 cooperate to guide the lifting movement of the lifting support 3, preventing deviation and swaying during lifting, and reducing movement resistance. Preferably, the lifting guide rail 11 is a U-shaped guide rail, and the lifting guide wheel 32 is disposed within the U-shaped guide rail, which can provide good guidance.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
