Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture silo maintenance devices, and specifically to an asphalt mixture silo maintenance device. Background Art

[0002] The main process flow of hot-mix recycling equipment in an asphalt mixture plant is as follows: recycled material distribution, lifting, drying and heating, storage, metering, and transportation to the primary mixing tank. The storage stage temporarily stores the heated recycled material in a temporary regeneration storage bin, while the exhaust gas generated by the equipment first passes through an exhaust chamber to filter out large particles before being discharged into the primary equipment for secondary treatment. The dried aggregate in the storage stage continues to be moved by an elevator and eventually falls into the silo through the top of the silo. The falling aggregate is shaken and screened to separate aggregates of different particle sizes. This shaking and screening process generates a large amount of dust. In the existing technology, a dust collector is used to absorb this scattered dust, and excess pressure in the silo is released through a safety valve to prevent over-pressurization. However, when the dust collector absorbs the scattered dust, some of it may clog the safety valve, posing a safety hazard to the silo. Therefore, regular manual inspection of the safety valve on the upper side of the silo is required.

[0003] In the prior art, interconnected maintenance platforms are provided on the upper sides of multiple silos to facilitate maintenance and inspection work by workers. The existing maintenance method requires maintenance workers to move to the upper side of a designated silo through the maintenance platform, and then fix the other end of a safety rope fixedly connected to the maintenance worker to the railing on the side of the maintenance platform. Then, the maintenance worker drills out of the gap between the railings, and then slowly climbs down through the scaffolding built on the upper side of the silo by the maintenance platform, and finally falls onto the silo, so that the safety valve on the designated silo can be inspected. This maintenance method requires workers to hold the maintenance tools with one hand and deal with the threat of climbing at the same time, thereby increasing the difficulty of maintenance for the workers and increasing the risk of work.

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example

[0031] like Figures 1 to 6 As shown, this embodiment proposes an asphalt mixture silo maintenance device, including several silos 11, a lifting device 12 for transporting aggregates, and a maintenance platform 13. The lifting device 12 is connected between the silos 11, and the maintenance platform 13 is fixedly connected to the upper side of the several silos 11;

[0032] Several flip fences 21 are hinged on the maintenance platform 13. The maintenance platform 13 is slidably connected to the support plate 22 on the side close to the flip fence 21. The support plate 22 is fixedly connected to the receiving block 23 on one side. Two limit posts 24 are slidably connected to the receiving block 23. Two limit plates 25 are fixedly connected to the two ends of the two limit posts 24 respectively.

[0033] A lifting assembly for lowering workers from the maintenance platform 13 to the top of the silo 11 is connected to the support plate 22;

[0034] The lifting assembly can facilitate multiple workers to reach the top of the silo 11 from the maintenance platform 13, so that the tool boxes carried by the workers can be moved along with it, so that multiple workers can simultaneously perform maintenance, replacement or emergency repairs on the components on the top of the silo 11, which is convenient for the workers to maintain the silo 11, making the workers' work more labor-saving and safe, reducing the difficulty of the workers' work and ensuring the safety of the workers during work. In addition, when the silo 11 leaks and smoke and dust are filled, the workers can quickly transfer from the top of the silo 11 through the receiving cabinet 37;

[0035] A limiting assembly for limiting the position of the flip fence 21 in conjunction with the movement of the support plate 22 is connected to the outside of the flip fence 21;

[0036] The limiting assembly cooperates with the lifting assembly to limit and clamp the flip fence 21, so that the flip fence 21 that is not in operation is tightly clamped, thereby ensuring the safety of other workers walking on the maintenance platform 13.

[0037] like Figures 1 to 5As shown, the lifting assembly includes a flip block 31 and a flip cylinder 41. The flip block 31 is fixedly connected to the side of the support plate 22. The lifting seat 32 is rotatably connected to the flip block 31. Two polished rods 33 are fixedly connected to the lifting seat 32. The transmission block 34 is slidably connected to the two polished rods 33. The transmission screw 35 is threadedly connected to the transmission block 34. The transmission screw 35 is rotatably connected to the lifting seat 32.

[0038] The transmission block 34 is fixedly connected to the receiving plate 36 on the side away from the lifting seat 32, and the receiving cabinet 37 is fixedly connected to the receiving plate 36;

[0039] The drive motor 38 is fixedly connected to the lower side of the lifting seat 32, and the drive shaft of the drive motor 38 is fixedly connected to the transmission screw 35;

[0040] The distance between the receiving cabinet 37 and the top of the silo 11 is directly controlled by the driving motor 38, which makes it convenient for the staff to move safely from the receiving cabinet 37 to the top of the silo 11, and the tools they carry with them can be placed on the receiving cabinet 37 and move with the receiving cabinet 37, so that the staff can save more effort when inspecting the safety valve on the top of the silo 11, ensuring the safety of the staff's work.

[0041] like Figures 1 to 5 As shown, the flip cylinder 41 is fixedly connected to the support plate 22, the telescopic shaft on the flip cylinder 41 is hinged to the linkage plate 42, and the linkage plate 42 is fixedly connected to the side of the lifting seat 32;

[0042] The telescopic shaft of the flipping cylinder 41 can drive the lifting seat 32 to rotate around the flipping block 31 through the linkage plate 42, thereby adjusting the angle and distance between the receiving cabinet 37 and the maintenance platform 13 toward the side of the maintenance platform 13. When the telescopic shaft of the flipping cylinder 41 contracts, the receiving cabinet 37 can be brought closer to the maintenance platform 13, so that the staff can move to the receiving cabinet 37 more safely, and when the telescopic shaft of the flipping cylinder 41 is extended, the receiving cabinet 37 can be adjusted to move down to close to the top of the silo 11, which facilitates the staff to move from the receiving cabinet 37 to the top of the silo 11.

[0043] like Figures 3 to 6 As shown, the side of the maintenance platform 13 is fixedly connected to the coupling plate 51, the coupling groove 52 is opened on the coupling plate 51, the support plate 22 is fixedly connected to the coupling block 53 on the side facing the coupling plate 51, and the coupling block 53 abuts against the inner wall of the coupling groove 52;

[0044] When the connecting block 53 is subjected to a downward force, the connection strength between the connecting block 53 and the side of the maintenance platform 13 can be increased through the abutment relationship between the connecting block 53 and the inner wall of the connecting groove 52, thereby reducing the working pressure of the receiving block 23 and making the sliding of the receiving block 23 more stable.

[0045] like Figures 3 to 6 As shown, the limiting assembly includes a locking seat 61, which is fixedly connected to the side of the connecting plate 51, a locking column 62 is slidably connected to the locking seat 61, a locking plate 63 is sleeved on the locking column 62, and a transmission column 64 is fixedly connected to the locking plate 63;

[0046] The locking spring 65 is sleeved on the locking column 62, and the two ends of the locking spring 65 are respectively in contact with the locking seat 61 and the locking plate 63;

[0047] The movement of the support plate 22 can squeeze the locking spring 65 through the locking plate 63, thereby disengaging the transmission column 64 from the flip fence 21, so that the staff can inspect the top of the silo 11 through the flip fence 21 on this side, while the locking plate 63 on the side of the flip fence 21 at other positions is not subjected to any force, so the flip fence 21 at other positions can be pinned to protect the side of the maintenance platform 13 and ensure the safety of the staff walking on the maintenance platform 13.

[0048] like Figures 1 to 6 As shown, the locking hole 211 is opened on the side of the lower side of the flip fence 21 away from the hinged position of the maintenance platform 13. The aperture of the locking hole 211 is slightly larger than the transmission column 64, so that the transmission column 64 can hold the flip fence 21 without being affected by external force, thereby preventing the flip fence 21 from flipping and deviating.

[0049] like Figure 5 and Figure 6 As shown, the force transmission column 321 is fixedly connected to the lifting seat 32, and the force transmission column 321 is arranged in a ring shape. The staff can control the movement of the lifting seat 32 through the force transmission column 321, and it is convenient for the staff to align the lifting seat 32 with the flip fence 21 on one side through the force transmission column 321, so that the staff can move to the receiving cabinet 37 through the flip fence 21 on this side, and the force transmission column 321 can be used as a handrail, and one end of the safety rope can be wrapped around the force transmission column 321, so that the staff can pass through the force transmission column 321 and better get on the receiving cabinet 37.

[0050] The principle of this embodiment is:

[0051] When multiple workers need to repair the top of the silo 11, they can go to the top of the maintenance platform 13 via the external ladder connected to one end of the maintenance platform 13, and then walk to the top of the silo 11 that needs maintenance via the maintenance platform 13. The position of the lifting seat 32 is pulled by the force transmission column 321, so that the support plate 22 moves to the side of the flip fence 21 on that side. That is, the lifting seat 32 moves into place, and the moving inertia of the support plate 22 hits the locking plate 63, forcing the transmission column 64 to disengage from the locking hole 211. The worker can then flip the flip fence 21 that has lost the locking of the transmission column 64, and finally move it from the flip fence 21 to the receiving cabinet 37. During this process, the worker controls and drives the flip cylinder 41:

[0052] The telescopic shaft of the tilting cylinder 41 can drive the lifting seat 32 to rotate around the tilting block 31 through the linkage plate 42, thereby adjusting the angle and distance between the receiving cabinet 37 and the maintenance platform 13. When the telescopic shaft of the tilting cylinder 41 is retracted, the receiving cabinet 37 can be brought closer to the maintenance platform 13, so that the staff can move to the receiving cabinet 37 more safely. In addition, when the telescopic shaft of the tilting cylinder 41 is extended, the receiving cabinet 37 can be adjusted to move down to near the top of the silo 11, which facilitates the staff to move from the receiving cabinet 37 to the top of the silo 11.

[0053] Then, the receiving cabinet 37 is driven by the driving motor 38 to move up and down, so that multiple workers located on the receiving cabinet 37 can move smoothly to the top of the silo 11.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
