Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of vibroflotation construction, specifically relates to a caterpillar type weighing and discharging device for vibroflotation construction. BACKGROUND
[0002] Before the construction of a hydropower station, the foundation thereof needs to be reinforced. At present, the reinforcement is generally carried out by a vibroflotation method to improve the bearing capacity, liquefaction resistance and other parameters of the foundation. The vibroflotation construction mainly includes two stages, i.e., vibroflotation hole drilling and filling material vibroflotation compaction. In the vibroflotation construction, the control of the filling material is an important means for the quality control of the vibroflotation pile.
[0003] At present, the filling material method of the vibroflotation pile generally includes three kinds, i.e., the first method is to use a loader to fill the material, the advantage of which is strong mobility and strong environmental adaptability, but the disadvantage is that it cannot guarantee that each shovel of material is added to the hole position, and it is not convenient to control the amount of material to be put. The second method is to use a belt conveyor to weigh and feed the material, which is generally used for fixed-point feeding, and is difficult to adapt to the occasions with large range of site changes, many cross operations and many types of work. The third method is to use a metering weighing hopper, the advantage of which is accurate metering and accurate feeding of the material, but the disadvantage is poor mobility, which needs to rely on a crane for movement, poor mobility and poor environmental adaptability.
[0004] In addition, although the amount of filling material in the current vibroflotation process can be detected, the above-mentioned several methods, especially the loader filling method and the belt conveyor filling method, can accurately weigh the material, but the filling method determines that a considerable amount of material will be retained near the pile hole, resulting in a large difference between the recorded amount of filling material and the actual amount of filling material entering the pile hole, which forms an unstable factor for the quality control of the vibroflotation pile.
[0005] Therefore, the inventor designs a caterpillar type weighing and discharging device for vibroflotation construction to solve at least one of the above problems. SUMMARY
[0006] The purpose of the present application is to provide a caterpillar type weighing and discharging device for vibroflotation construction to solve the problem of poor mobility of the metering weighing hopper in the current vibroflotation construction process.

[0041] The utility model will be described in detail below by referring to the drawings and combining with the embodiments.
[0042] As shown in Figure 1 and Figure 2 The utility model provides a caterpillar type weighing and discharging device for vibroflotation construction, which comprises a frame main body 1 with two caterpillar tracks 11 and a hopper main body 2 arranged on the frame main body 1.
[0043] It also comprises a weighing assembly arranged at the bottom of the hopper main body 2, an inclined material sliding groove 22 arranged at the discharge port of the bottom of the hopper main body 2 and a discharging bag 23.
[0044] The discharging bag 23 is provided with a rigid discharge frame 24 at the end away from the material sliding groove 22, and at least one insertion rod 241 is fixed to the bottom of the rigid discharge frame 24.
[0045] The discharge port of the bottom of the hopper main body 2 is also provided with a material control assembly on the weighing assembly.
[0046] The utility model sets the frame main body 1 with the caterpillar track 11, and the hopper main body 2 is arranged on the frame main body 1, so that the hopper main body 2 of the application can be transferred through the frame main body 1 with the caterpillar track 11, and can adapt to various construction environments, thereby effectively solving the poor mobility of the metering and weighing hopper in the prior art.
[0047] In addition, this embodiment sets up a material chute 22 and a flexible material feeding bag 23, and a rigid material feeding frame 24 is provided at the outlet end of the material feeding bag 23. An insertion rod 241 is provided at the bottom of the rigid material feeding frame 24, so that after the frame body 1 moves to the vicinity of the pile hole, the insertion rod 241 of the rigid material feeding frame 24 can be inserted into the position close to the pile hole to ensure accurate feeding position.
[0048] In this embodiment, after the rigid discharge frame 24 is inserted into the ground, the vibration of the ground can be transmitted to the rigid discharge frame 24 and the discharge bag 23 through the insertion rod 241 as the vibrator vibrates, so that the material discharged from the hopper body 2 will not stay in the chute 22 and the discharge bag 23, thereby ensuring the accuracy of the feeding amount.

[0058] In the embodiment, a hydraulic pump and a power module are further arranged on the frame main body 1.
[0059] The hydraulic pump is electrically connected with the power module.

In the embodiment, since the frame main body 1 is arranged, the power supply problem of the hydraulic pump is also solved, and re-wiring on the construction site is avoided, thereby reducing the clutter phenomenon on the construction site.
[0061] In the embodiment, as shown in Figure 1 The weighing assembly comprises a weighing support plate 41 and a plurality of piezoelectric sensors 42 arranged below the weighing support plate 41.
[0062] The hopper main body 2 is arranged on the weighing support plate 41. In the embodiment, the piezoelectric sensors 42 can accurately monitor the change of the weight of the material in the hopper main body 2, thereby facilitating the control of the amount of the discharged material.
[0063] In the embodiment, as shown in Figure 1 The support frame 5 is arranged on the frame main body 1, and the top of the support frame 5 is provided with a support seat plate 51.
