Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of recycled aggregate concrete block processing, especially relates to a recycled aggregate concrete block preparation device. BACKGROUND

[0002] Recycled aggregate concrete is a kind of aggregate concrete that can be reused after the recycling and processing of waste building materials. Specifically, with the continuous development of urban construction, a large number of old and illegal buildings need to be demolished and rebuilt to meet the needs of urban development.

[0003] Therefore, urban construction is accompanied by the demolition of a large number of old and illegal buildings, and the demolition of buildings will inevitably generate a large amount of construction waste. According to incomplete statistics, construction waste accounts for 40% of the total amount of urban waste, including production and living waste.

[0004] Therefore, the environmental and harmless treatment of a large amount of construction waste has become one of the difficulties of urban construction. In order to realize green and recyclable development, a large amount of construction waste is recycled and utilized, such as being used as a concrete material, which not only effectively solves the pollution problem of construction waste, but also realizes green and cyclic utilization of resources.

[0005] After processing, different types of concrete materials are obtained, such as recycled construction waste aggregate, which is processed into concrete blocks and re-applied to construction engineering. Specifically, after processing, concrete materials are obtained, which are discharged into molds, and then subjected to static curing, heat treatment and other processes to obtain concrete blocks. The size and shape of the concrete blocks are different according to their different purposes.

[0006] In the process of construction, long concrete blocks are often needed, such as strip-shaped blocks used as beams, so the size of the building structure beam needs to be customized during production. After the production of the blank, it needs to be hoisted to the workbench, and finally the hardness of the finished product is increased through heat treatment.

[0007] However, due to the insufficient hardness of the blank, it is impossible to avoid collision and impact between the blank and the workbench during hoisting and discharging, so improper operation, such as improper force control, often causes deformation of the blank, and the shape and size of the finished product after high-temperature treatment do not meet the requirements.

[0044] Embodiment 1

[0045] As Figures 1-6 shown, a recycled aggregate concrete block preparation device comprises a concrete block blank hoisting and feeding mechanism. The concrete block blank hoisting and feeding mechanism is used to feed the prefabricated concrete block to the feeding table (in the existing construction process, the feeding table is pushed into the high-temperature steam furnace for heat treatment and hardening of the feeding table).

[0046] Specifically, the concrete block blank hoisting and feeding mechanism comprises a mold frame 1 (the mold frame 1 has a rectangular transverse cross-sectional shape, and the length is 1.5-2 m, which is suitable for feeding block blanks with relatively large lengths such as cylindrical and cuboid shapes), and a discharging plate 2 is hingedly connected to the bottom of the mold frame 1.

[0047] Specifically, the right side wall of the discharging plate 2 is fixedly connected with a plurality of L-shaped hinged plates 21, the side wall of the mold frame 1 is provided with a hinge opening for hingedly connecting the L-shaped hinged plates, and the L-shaped hinged plates 21 are hingedly connected in the hinge opening through a pin shaft.

[0048] In actual work process, according to the height of the blank, long notches are formed in the left side wall of the mold frame 1 when the blank height is relatively large, so that the blank can slide down along the discharging plate 2 to the left side after the discharging plate 2 is turned over, and the long notches facilitate the discharge of the blank.

[0049] Meanwhile, two front and rear spaced discharging ropes 4 (the discharging rope 4 is double-stranded) are fixedly connected to the bottom of the discharging plate 2; the discharging rope 4 is hung outside the mold frame 1. Specifically, in order to fix the discharging rope 4 and prevent the discharging rope 4 from slipping relative to the discharging plate 2 and the mold frame 1 during hoisting, a locking pipe A for locking the discharging rope 4 is fixedly connected to the bottom of the discharging plate 2; the discharging rope penetrates through the locking pipe A.

[0050] The same as the existing lifting method, the crane is used to pull and hang on the discharging rope 4, and the hanging of the discharging rope 4 on both sides maintains high suspension stability and safety.

[0051] When hoisted to the upper side of the feeding table, at this time, the hook of the crane is hung on the following anti-collision cage mechanism, at this time, the discharging rope is not stressed, and the discharging plate 2 is turned over due to the loss of support of the discharging rope, at this time, the blank slides down along the slope surface of the discharging plate 2, in order to avoid the deformation of the blank caused by the impact of the blank with insufficient hardness after sliding down too fast, the recycled aggregate concrete block preparation device further comprises a plurality of concrete block blank auxiliary discharging mechanisms fixedly installed on the mold frame 1.

[0052] Specific is, the unloading plate 2 flips unloading process, through the concrete block blank auxiliary unloading mechanism support unloading; That is, the concrete block blank auxiliary unloading mechanism in the blank down process, resist blank one to reduce the down speed, two to achieve protection blank, avoid unloading process, resulting in blank damage.

[0053] Specific is, the concrete block blank auxiliary unloading mechanism all includes fixedly connected on the mold frame 1 on the hinge vertical plate 51 (specific is located in the left side wall of the mold frame 1, blank down direction is also left side), the hinge vertical plate 51 is hinged with the turnover arm 52, the lower end of the turnover arm 52 is assembled and connected with the support bracket 53, the support bracket 53 is rotatably connected with the abutting roller 54 (the rotatable connection mode is the same as the existing conventional mode, the both ends of the abutting roller 54 are fixedly connected with the rotating shaft, and the rotating shaft is rotatably connected with the support bracket 53 of U-shaped structure); When the unloading plate 2 flips unloading process, the concrete block blank slides along the unloading plate 2, the rotating turnover arm 52 is rotated to the abutting roller 54, which abuts on the concrete block blank, and the turnover arm 52 is synchronously flipped with the unloading plate 2 until the concrete block blank unloading is completed.

[0054] Specifically, the hinge vertical plate 51 is provided with a long hinge opening, and the upper end of the turnover arm 52 is hinged in the long hinge opening through a fixed pin shaft.

[0055] In the working process, when the blank slides along the unloading plate 2 to partially separate from the mold frame 1, at this time, the turnover arm 52 is turned over to the support bracket 53 connected with the turnover arm 52-abutting roller 54 (the abutting roller 54 is made of rubber material), the abutting roller 54 constantly abuts on the blank, and the blank constantly slides down, at this time, the angle of the turnover arm 52 is constantly adjusted (the operator flips the handle rod), to ensure that the abutting roller 54 can abut on the blank during the whole process of blank unloading, and the blank unloading speed is slowed down under the abutting of the abutting roller 54, until it is stably dropped on the table.

[0056] By the above-mentioned mode, the unloading process is realized, and the unhardened blank is protected, especially the special customized large size concrete cutting fast, which realizes the protection mode unloading, so as to solve the defect that the large size concrete cutting fast with insufficient hardness is easily damaged by impact in the unloading process due to its too heavy.

[0057] Specifically, the shape of the above-mentioned support bracket 53 is U-shaped, the top of the support bracket 53 is fixedly connected with an inner spring rod slidingly connected in the turnover arm 52 (the turnover arm 52 is provided with a sliding cavity adapted thereto, and the inner spring rod is limitedly slid in the sliding cavity in the same way as the existing sliding structure), the inner spring rod is sleeved with a spring 55, and the both ends of the spring 55 are fixedly connected with the support bracket 53 and the turnover arm 52.

[0058] During the process of contacting the blank through the internal spring rod and spring structure, the support bracket 53-contact roller 54 can be telescopically adjusted, thereby achieving full contact between the contact roller 54 and the center of the blank. During the process of contacting the blank through the spring structure, the support bracket 53 is continuously and flexibly adjusted as the blank is unloaded. When the blank is unloaded and partially contacts the material table, the pressure on the support bracket 53-contact roller 54 continues to decrease. At this time, the spring structure can quickly adjust the length of the support bracket 53-contact roller 54 to facilitate the unloading of the blank.

[0061] Specifically, the anti-collision cage mechanism includes several longitudinal U-shaped cage rods 31 distributed longitudinally, and the anti-collision cage mechanism also includes several transverse U-shaped cage rods 32 (welded at the cross position) arranged crosswise with the longitudinal U-shaped cage rods 31; the upper end of the outer wall of the mold frame 1 is fixedly connected with several bent hook rods installed on the longitudinal U-shaped cage rods 31 and the transverse U-shaped cage rods 32.

[0062] At the same time, the hook rod is connected to the corresponding longitudinal U-shaped cage rod 31 and the transverse U-shaped cage rod 32 through a detachable connecting piece; the detachable connecting piece includes a lower nut 33 threadedly connected to the hook rod, and the top of the lower nut 33 is fixedly connected to a fastening screw fastened in the corresponding longitudinal U-shaped cage rod 31 and the transverse U-shaped cage rod 32.

[0063] After the blank is placed into the mold frame 1, the lower nut 33 of the detachable connecting piece (a threaded hole is provided on the lower nut 33) is pre-tightened to the bent hook rod, and then the cage structure formed by the longitudinal U-shaped cage rod 31 and the transverse U-shaped cage rod 32 is aligned with the fastening screw 331 on each detachable connecting piece, and the lower nut 33 is screwed in the opposite direction (for easy screwing, the outer wall of the lower nut 33 is integrally formed with a hexagonal convex ridge) until the fastening screw 331 is threadedly fastened to the bottom of the longitudinal U-shaped cage rod 31 and the transverse U-shaped cage rod 32 (specifically, a threaded groove is provided on the bottom of the longitudinal U-shaped cage rod 31 and the transverse U-shaped cage rod 32).

[0064] The above structure forms a cover structure to cover and protect the concrete blanks with low hardness, and to prevent the concrete blanks from being deformed by collision with obstacles due to operational errors during suspension transportation.

[0065] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
