Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit construction, in particular to a jump-bin method construction device for foundation pit construction. Background Art

[0002] The skip-slot construction method is an advanced technology used in the construction of large-scale concrete structures, particularly in deep foundation pits. The core of this method involves dividing an overlong concrete block into several smaller blocks. By constructing the blocks at intervals, the concrete is allowed to release stress early in the process, and then these smaller blocks are connected to form a whole later. This allows the concrete's tensile strength to withstand the subsequent thermal shrinkage stress, effectively preventing cracks.

[0003] At present, when carrying out the foundation pit skipping method construction, it is inevitable to use concrete pouring equipment. However, during the actual pouring process, the pouring angle of the discharge pipe cannot be flexibly adjusted, which makes it inconvenient to adapt to the complex and changeable foundation pit construction environment.

[0024] Reference Figure 1-4 A construction device using a skipping method for foundation pit construction includes a concrete pouring mechanism, a base 1 provided with a walking assembly, and a concrete storage tank 2 fixedly connected to the top outer wall of the base 1;

[0025] In this embodiment, the walking assembly includes four universal wheels with brakes fixedly mounted at the four corners of the bottom of the base 1 and a push handle 20 welded to the top outer wall of the base 1. A filling pipe 19 is provided in front of the concrete storage tank 2. The concrete pouring mechanism includes:

[0026] The conveying inclined cylinder 3 is hinged to the top of the concrete storage tank 2;

[0027] The material pump 4 is fixedly mounted on the top outer wall of the base 1;

[0028] A hydraulic electric push rod 5 is hinged between the conveying inclined cylinder 3 and the concrete storage tank 2;

[0029] The concrete conveying assembly includes a transmission shaft 6 rotatably mounted in the conveying inclined cylinder 3, an auger 7 welded to the outer wall of the transmission shaft 6, and a conveying motor 8 fixedly connected to the outer wall of the bottom of the conveying inclined cylinder 3. The output shaft of the conveying motor 8 is connected to the inner wall of the bottom of the conveying inclined cylinder 3 through a sealed bearing. The output shaft of the conveying motor 8 is coaxially fixedly connected to the bottom end of the transmission shaft 6 through a coupling.

[0030] The pipe connection assembly includes a feed pipe 9 fixedly connected to the upper part of the conveying inclined cylinder 3 and a universal metal hose 10 fixedly connected to the lower part of the conveying inclined cylinder 3. The extraction end of the material pump 4 is connected to the concrete storage tank 2 through the extraction end, and the feeding end of the material pump 4 is connected to the bottom end of the universal metal hose 10 through the feeding pipe;

[0031] A stirring assembly comprising a driving component, two stirring shafts 11 which are sequentially rotatably mounted in the concrete storage tank 2, and two double-helical stirring blades 12 which are sequentially fixedly connected to the two stirring shafts 11;

[0032] Furthermore, the driving components include a fixing frame 13 welded to the outer wall of the concrete storage tank 2, a control motor 14 fixedly mounted on the side wall of the fixing frame 13, two first linkage gears 15 fixedly mounted on one end of the two stirring shafts 11 in sequence, a driving gear 16 fixedly mounted on the output shaft of the control motor 14, a linkage shaft 17 rotatably mounted on one side of the fixing frame 13 and a second linkage gear 18 fixedly mounted on the linkage shaft 17. The second linkage gear 18 and the first linkage gear 15 located below are both engaged with the drive gear 16, and the first linkage gear 15 located above is engaged with the second linkage gear 18.

[0033] The working principle of this embodiment is as follows: First, the concrete in the concrete storage tank 2 is pumped out by the material pump 4 and delivered to the delivery inclined cylinder 3 through the delivery pipe and the universal metal hose 10;

[0034] Secondly, the conveying motor 8 controls the auger 7 on the transmission shaft 6 to rotate in the conveying inclined cylinder 3, conveying the conveyed concrete from bottom to top, and finally discharging it from the discharge pipe 9 for pouring. In the actual pouring process, the hydraulic electric push rod 5 arranged in a hinged manner can flexibly adjust the pouring angle of the discharge pipe 9, thereby facilitating adaptation to the complex and changeable foundation pit construction environment.

[0035] Finally, the driving gear 16 is controlled by controlling the motor 14 to rotate forward, and then the first linkage gear 15 and the second linkage gear 18 below that are engaged with the driving gear 16 will rotate in the opposite direction, and then the first linkage gear 15 above that is engaged with the second linkage gear 18 will rotate forward, thereby causing the two double-helix stirring blades 12 connected to the two stirring shafts 11 to rotate in the opposite direction. In this way, the concrete in the concrete storage tank 2 can be fully stirred by the two double-helix stirring blades 12 with opposite rotation directions, which can effectively prevent the concrete from solidifying, improve the use effect of the concrete, and thus help to improve the subsequent pouring construction quality.
