Abstract
Description

[0002] The proposed site is for the construction of heliostat pile foundations in the mirror field, with a total of 23,732 piles, an area of 2.85 million m2, and a spacing of 8m-14m between heliostat piles. The construction site is a thick silt sand layer. Due to cost reasons, the roads for construction vehicles in the site cannot cover the entire construction area. Only a few main construction roads are built for heavy vehicles such as concrete tankers. The tankers are stuck in the sand and cannot complete the self-unloading work, so measures need to be taken to transport the concrete to the column piles. Under the existing conditions, the common equipment for transporting concrete over long distances is concrete pump trucks (sky pumps) and concrete trailer pumps (ground pumps). Sky pumps are more convenient but expensive. The area covered by the pump pipe after extension is limited, the body is heavy, and the requirements for the road are high; ground pumps are low in cost and flexible in placement, but the operation is complicated and requires about 4 people to continuously disconnect and connect the pump pipes, which is time-consuming and has a high cost of operation and maintenance time. The unloading volume is small in the same time, which delays the construction period. Utility Model Content

[0021] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.
[0022] Example 1
[0023] The utility model is suitable for the equipment of concrete transportation and self-unloading with stable driving in fine sand strata. It is a modification of the existing driving vehicles. Common driving platforms are crawler excavators and wide-wheeled shovels. Finally, a shovel is used as the driving platform because the shovel starts and drives smoothly and maintains a fast stable driving speed. As a driving vehicle, the shovel has wide tires with a large contact area with the ground, low squeezing effect on the strata, small impact on the pile hole, fast concrete transportation, and the bucket capacity of the shovel is much larger than that of the excavator. Considering various factors, the shovel is the best option as a driving platform; secondly, in order to facilitate the transportation and pouring of concrete, the shovel bucket needs to be modified. Figure 1 As shown, the forklift body 1 includes a forklift body 1, and the forklift body 1 is controlled and connected to a bucket 2. Figure 2 As shown, a 30 cm circle hole 3 is opened on the bottom surface of both sides of the bucket 2, and the circle hole 3 is polished and smooth. An iron tubular chute 5 extending to the side direction is welded on each circle hole 3 of the bucket 2. The iron tubular chute 5 is used to circulate concrete. Figure 3 As shown, each iron tubular chute 5 is provided with a slit 6, and each iron tubular chute 5 is flexibly connected to a manually-activated steel plate baffle 4 at the slit 6.
[0024] Before putting concrete in, the hand-opened steel plate baffle 4 is turned to separate the inside of the iron tubular chute 5. After putting concrete in the bucket 2, it is transported to the heliostat column pile in the mirror field by the forklift 1, and the hand-opened steel plate baffle 4 is turned to open the iron tubular chute 5 to let the concrete in the bucket 2 flow out.
[0025] Due to the stability of the forklift 1 in walking, the concrete will not flow out from the cut seam 6.
[0026] The cut slit 6 is opened from top to bottom by the iron tubular chute 5. During the transportation process, the hand-opened steel plate baffle 4 can always be in the cut slit 6 under the action of gravity, thereby blocking the concrete.
[0027] The utility model is suitable for the stable concrete transportation and self-unloading equipment in fine sand strata. The forklift is used as the traveling platform. The short-distance concrete transportation and self-unloading equipment after the forklift bucket is modified can effectively ensure the stability and efficiency of concrete transportation in sandy land. Compared with the traveling carrier excavator, it saves the equipment rental cost, and compared with the sky pump and the ground pump, it improves the efficiency of concrete pouring and reduces the pouring cost. It has strong operability and applicability, less waste of concrete, and saves resources.
[0028] Example 2
[0029] On the basis of Example 1, the hand-opening steel plate baffle 4 used in this embodiment is as follows Figure 4As shown, it includes a steel plate baffle 4-2, to which a triangular stabilizing structure handle 4-1 is connected, and the steel plate baffle 4-2 is also connected to a baffle ear 4-3, on which a bolt hole 4-4 is provided, and the bolt hole 4-4 of the baffle ear 4-3 is connected to a slit 6 on the iron tubular chute 5 through an active component.
[0030] Among them, the triangular stable structure handle 4-1 facilitates the rotation operation of the steel plate baffle 4-2.
[0031] The steel plate baffle 4-2 can play an internal barrier role on the iron tubular chute 5 under the driving effect of the triangular stable structure handle 4-1.
[0032] The baffle ear plate 4-3 can increase the stability of the connection between the steel plate baffle plate 4-2 and the active components on the iron tubular chute 5.
[0033] The steel plate baffle 4 - 2 can rotate around the active component, thereby playing an internal blocking or flow-through role for the iron tubular chute 5 .
[0034] The active component includes two fixed ear plates 4-5 fixedly connected to the slit 6 on the iron tubular chute 5. The two fixed ear plates 4-5 are rotatably connected to the baffle ear plate 4-3 through bolts passing through the bolt holes 4-4. M16 bolts can freely pass through the fixed ear plates 4-5. The baffle ear plate 4-3 is arranged on one side of the steel plate baffle plate 4-2 and is firmly welded to the steel plate baffle plate 4-2.
[0035] The area of the steel plate baffle 4-2 is not less than the inner cross-sectional area of the iron tubular chute 5, and can completely block the outflow of concrete during transportation.
[0036] Example 3
[0037] On the basis of Example 1, the end of the iron tubular chute 5 is an inclined opening slot, the length of which can be flexibly adjusted on site according to the pouring conditions, and can buffer the outflowing concrete to prevent blockage.
[0038] The iron tubular chute 5 forms an angle of 30° with the plane where the bottom of the bucket 2 is located, preventing the bucket 2 from touching the ground in the vertical direction.
[0039] The width of the slit 6 is 7 mm, which allows the steel plate baffle 4-2 with a thickness of 5 mm to rotate freely.
[0040] Through the above manner, the utility model is suitable for equipment for transporting and unloading concrete stably in fine sand strata, suitable for various surface conditions, and also suitable for thick sandy areas. By modifying the bucket of the forklift, it satisfies the requirement of transporting concrete over short distances and completing concrete pouring work under the premise of stable travel. It has the characteristics of convenient pouring, fast transportation, low cost, flexible pouring of small-volume pile foundations and rapid transfer to the next pouring point after pouring, strong practicality and high reliability, solves the problem of concrete pouring of the column piles of the heliostat in the mirror field, and saves construction period and cost.
