[0036] Specifically, Figure 1 As shown, in one embodiment, a lifting lug 21 is provided on the distribution hopper 20 to facilitate lifting.
[0037] Combine the following Figures 1 to 3 , a more complete embodiment of the present application is described below:
[0038] The utility model provides a material distribution hopper device, which comprises a material hopper, a lifting ring, a material distribution pipe, a fixing rib, a steel wire rope and a rope clamp, and a material discharge switch.
[0039] Specifically, the hopper is processed from a steel plate into a four-sided platform. The side of the hopper is a congruent isosceles trapezoid, the bottom is a square, and the ground and the side are welded firmly to each other. There are two circular holes at the bottom of the side, and the concrete flows into the distribution pipe through the circular holes. The processing dimensions of the isosceles trapezoid on the side of the hopper and the bottom plate need to be determined by calculation, one is the capacity of the concrete, and the other is the inclination angle of the isosceles trapezoid (to ensure that after the distribution pipe is installed, the angle of the distribution pipe matches the distance between the legs of the slipform operation platform). Its height can be adjusted according to actual needs.
[0040] Specifically, the lifting ring is made of steel plates or steel bars, and its function is to facilitate the lifting, installation and removal of the material distribution hopper.
[0041] Specifically, the material distribution pipe is symmetrical on the left and right, is made of steel plates, and is modified from the "material pipes" commonly seen on construction sites.
[0042] The diameter of the material distribution pipe matches the hole set on the hopper, and the diameter is preferably 200mm. Fixed ribs are set at appropriate positions on the material distribution pipe. The function of the fixed ribs is to fix the material distribution pipe. The fixed ribs are tied and fixed to the legs of the slipform lifting frame by steel wire ropes and fastened by rope clamps.
[0043] Specifically, the discharge switch is a rotary opening and closing structure, which is an attached device of the concrete material pipe and is more commonly found on the concrete hopper material pipe. Its purpose is to discharge concrete and control the concrete flow speed.
[0044] Specifically, the hopper is fixedly installed by a steel pipe frame. The upper and lower two longitudinal and transverse steel pipes are connected to form two upper and lower closed hoops, and four oblique steel pipes are used to connect the upper and lower corners to form a fixed frame to fix the hopper. The rods are connected by rotating fasteners.
[0045] Specifically, the upper closed hoop longitudinal horizontal rod is fixed to the outer vertical rod through a right-angle fastener, and the lower closed hoop longitudinal horizontal rod is fixed to the inner vertical rod through a right-angle fastener. There are two rows of vertical rods on the left and right. The bottom of the vertical rod is fixed on the operating platform.
[0046] Specifically, the vertical poles are connected vertically and horizontally through large cross bars and small cross bars (first and second cross bars). The distance between the lowest large and small cross bars and the operating platform should be no less than 200mm. The horizontal spacing between large and small cross bars should be 500 or 600mm, and the large and small cross bars should avoid conflict with the cross beams of the sliding formwork lifting frame.
[0047] Specifically, the ends of the two small cross bars at the bottom are properly squeezed, and bolt holes are set at the squeezed ends of the small cross bars. The two small cross bars at the bottom are connected to the legs of the slipform lifting frame by bolts, and the bolt diameter is preferably M14 / M16. This connection is mainly to prevent the frame from overturning and provide a wall connection.
[0048] Specifically, scissors braces are set on the erected frame, and the scissors braces need to be set along the four sides of the frame from the bottom to the top, the purpose of which is to strengthen the overall structural connection of the frame.
[0049] Specifically, the device is fixed at the junction of the double-bin sliding form operating platform (the above-mentioned operating platform), installed on the sliding form outer operating platform (the above-mentioned operating platform), and the fixed frame is mainly connected to the sliding form operating platform and the lifting frame legs.
[0050] Specifically, on-site construction workers mainly discharge and transport concrete through the operating platform inside the slipform (located on the outer part of the operating platform). Because the concrete pouring volume during slipform construction is small (about 3.6m per day for sliding rise and about 160 to 200m per day for double-bin concrete pouring), the concrete pouring volume is relatively small. 3 ), the concrete can be transported to the silo wall pouring point by a wheelbarrow to complete the pouring of silo wall concrete.
[0051] This device improves and assembles common materials and devices on construction sites, designs concrete discharge as material division, and applies it to shallow silo slipform construction, so that concrete pouring of two shallow silos can be completed through one sky pump and one hopper. It reduces the demand for sky pump models and quantities and greatly reduces costs. This device has great promotion significance in the field of slipform construction.
[0052] Embodiment 2
[0053] like Figure 4As shown, the utility model also provides a sliding mold system, which includes an operating platform 300, two lifting frames 200 and the above-mentioned material dividing hopper device 100. The operating platform 300 is provided with two inner holes spaced along the first direction; the two lifting frames 200 are respectively arranged in the two inner holes; the material dividing hopper device 100 is fixed to the part of the operating platform 300 located between the two inner holes, and is fixedly connected to the two lifting frames 200.
[0054] It should be noted that the device sets the hopper on the slipform operation platform at the junction of adjacent silos, and distributes the concrete to two shallow silos through the distribution pipes. This allows one sky pump to meet the concrete pouring needs of two shallow silos, and at the same time, it only needs to transport the concrete to the distribution hopper, and the sky pump does not need to swing in a circular direction. This greatly reduces the demand for the number and model of sky pumps.
[0055] It should be noted that the device is easy to obtain materials, which are all common materials in construction sites, with simple structure and convenient installation, mainly for the erection of steel pipe frames. The device can be used repeatedly, and when one set of shallow circular silo slipforms is lifted, it can be dismantled and installed on the operating platform of the next set of shallow circular silo slipform system.
