Description

Technical Field

[0001] The invention relates to the technical field of cofferdam filling and soil loading, and in particular to a ton bag loading device for cofferdam filling and soil loading. Background Art

[0002] In the field of water conservancy and hydropower engineering, cofferdam is a temporary water retaining structure that can guide and control water flow, protect foundation pits, provide working space, etc. Although it is a temporary project, it plays an indispensable and important role in water conservancy projects. It directly affects the progress of the project, the safety of the project construction, the overall cost of the project, the quality of the main project construction, etc.

[0003] In conventional construction, underwater filling materials are mostly carried out in the dry season by the method of advancing from both ends to the middle. The filling volume is often larger than the designed volume. Due to the uncertainty of the geological conditions of the river channel, the construction cost and construction difficulty are increased. At the same time, the safety risks of machinery and equipment and personnel in the waterside area are extremely high. The filling materials at the project site are heavy silty loam and silty clay, which will soften when exposed to water. The filling body may become unstable under water pressure, causing landslides and collapses. For this reason, the conventional full-section homogeneous soil filling is adjusted to the filling method of following up with soil bags and homogeneous soil. The use of ton bags is large. The traditional method of filling ton bags with soil is manual bagging, which has low production efficiency and slow construction progress. If mechanical soil filling is used, although efficiency can be improved, it is necessary to wait until the transport vehicle arrives before mechanical soil filling into the ton bag in the car box. The waiting time of the transport vehicle is long, resulting in mechanical idleness.

[0038] Embodiment 1: like Figures 1 to 3 As shown in the figure, a device for loading ton bags of soil for cofferdam filling is provided, comprising a support frame 5, a support platform 3, and a lifting and sealing mechanism.

[0040] The support frame 5 serves as a support for the ton bag loading device, and supports the support platform 3 and the lifting and sealing mechanism.

[0041] The supporting platform 3 is composed of an openable and closable covering plate 301, which is rotatably connected to the supporting frame 5. The supporting platform 3 serves as a support for ton bags. The ton bags can be placed on the supporting platform 3 and then filled with soil. After the soil is filled, the supporting platform 3 is opened, the covering plate 301 is rotated downward, and the ton bags fall to the transport vehicle below.

[0042] The lifting and sealing mechanism includes a sealing support 14, a plug-in 15, a sealing lifting member 16, and a sealing hook 17. The sealing support 14 is vertically installed on the support frame 5, such as being located at one end of the support frame 5. The sealing support 14 can adopt a support rod structure, and the plug-in 15 is fixedly arranged on the top of the sealing support 14. The plug-in 15 can be an insertion ring or a fixed wheel. The sealing lifting member 16 is made of a soft material and can be deformed. For example, nylon material can be adopted, and it can be a nylon lifting rope. The lifting rope passes through the plug-in 15, and one end of the lifting rope is rotatably connected to the sealing hook 17, and the other end is rotatably connected to a sealing plate 301, and the lifting rope 16 is connected to the sealing plate 301 through a link position 18.

[0043] When the covering plate 301 rotates downward and opens, the ton bag filled with soil falls by gravity. At this time, due to the rotation of the covering plate 301, the sealing lifting member 16 connected thereto will pull the sealing hook 17 upward as the covering plate 301 rotates. The sealing hook 17 is lifted up to pull the drawstring at the opening of the ton bag, and the drawstring is pulled to achieve sealing. In this way, after the ton bag falls to the transport vehicle below, the sealing hook 17 is lifted for automatic sealing, and then the covering plate 301 is closed. As the covering plate 301 is closed, the sealing hook 17 is unhooked from the drawstring on the ton bag, thus forming an automatic unhooking mechanism, which enables the sealing hook 17 to flip upward and unhook due to the loss of tension, thereby completing the entire bagging and transportation process and entering the next cycle.

[0044] In this embodiment, the cover plate 301 has an openable and closable structure, and when the cover plate 301 is opened and started, the sealing hook 17 can pull the rope of the ton bag and start the sealing function synchronously, and there is no need to move the ton bag to the transport vehicle manually or mechanically. The ton bag can fall to the transport vehicle below by its own gravity by simply opening the cover plate 301, and this process does not require additional manual power or mechanical power. In addition, each loading device can load soil independently during loading, and the transport vehicle does not need to wait.

[0045] Furthermore, a load-bearing mechanism and a telescopic support mechanism are provided below the support frame 5. Specifically, Figure 1As shown in , the load-bearing mechanism includes a vertical support 2 and a transverse support 4, the vertical support 2 and the transverse support 4 are cross-fixedly connected, and the support frame 5 is fixedly connected to the transverse support 4 on all sides. The bottom space formed by the vertical support 2 and the transverse support 4 can be entered by a transport vehicle to receive ton bags. A load-bearing wheel is also provided at the bottom of the vertical support 2, and the load-bearing wheel can adopt a universal steering wheel structure to facilitate the movement of the entire device. In this embodiment, the entire load-bearing mechanism forms a stable support for the support platform 3 and the ton bag.

[0046] The telescopic end of the telescopic support mechanism is connected to the cover plate 301, and the fixed end of the telescopic support mechanism is connected to the load-bearing mechanism. The opening and closing of the support platform 3 is started by the telescopic movement of the telescopic support mechanism.

[0047] Specifically, the telescopic support mechanism designed in this embodiment includes a plurality of hydraulic telescopic rods 6, each of which is connected to the bottom of each cover plate 301, and the fixed ends of the plurality of hydraulic telescopic rods 6 are connected to the lateral support 4. Each hydraulic telescopic rod 6 is controlled to open or close the two cover plates 301, and the size of the opening or closing is controlled. In order to further save labor, a control switch 8 can be set on the load-bearing mechanism to control the opening and closing of the hydraulic telescopic rod 6.

[0048] In this embodiment, in order to better adapt to the sealing of ton bags of different sizes and heights, the sealing support 14 is designed to be a retractable structure, using a telescopic rod structure, which will not be described in detail.

[0049] Embodiment 2:

[0050] On the basis of Example 1, in order to further improve the efficiency of the ton bag filling process and prevent the soil from escaping from the ton bag, in this embodiment, a bag supporting mechanism that can be used to support the bag is designed, including a ton bag support frame 9, a ton bag hook 11, and a hook pull-down member 12.

[0051] The ton bag support frame 9 is arranged on the support frame 5. The ton bag support frame 9 is composed of multiple support rods, each of which is correspondingly provided with a ton bag hook 11. In this embodiment, a total of 4 support rods are arranged, and each support rod is vertically perpendicular to the support platform 3.

[0052] The ton bag hook 11 is rotatably connected to the ton bag support frame 9 to hook the four hanging rings on the ton bag. One end of the hook pull-down member 12 is rotatably connected to the ton bag hook 11, and the other end is rotatably connected to a covering plate 301. The figure shows the connection point 13 between the hook pull-down member 12 and the covering plate 301; preferably, the hook pull-down member 12 is a pull-down rod-shaped structure, and 4 hook pull-down members 12 are arranged, thereby forming an automatic unhooking structure.

[0053] When the cover plate 301 is opened, the ton bag filled with soil falls down, and the hook pull-down member 12 pulls the ton bag hook 11 to rotate and unhook from the ton bag as the cover plate 301 is opened. This process is the unhooking function.

[0054] When in use, first hang the hanging rings on the four corners of the ton bag on the ton bag hook 11 to support the ton bag. After the soil is loaded, the cover plate 301 is opened and the ton bag falls. At this time, the upper sealing function is turned on. At the same time, the unhooking function is also turned on. The hook pull-down member 12 rotates downward with the cover plate 301, pulls the ton bag hook 11 downward, and rotates with the ton bag hook 11 to make the ton bag hook 11 detach from the hanging ring of the ton bag. After completion, the cover plate 301 rotates upward to restore the natural state.

[0055] Better yet, a hook fixing section 10 is provided between each support rod and the corresponding ton bag hook 11, and the ton bag hook 11 and the hook fixing section 10 are rotatably matched. The hook fixing section 10 adopts a fixed rod structure, and there is an angle between the hook fixing section 10 and each support rod, which is inclined toward the direction of the supporting platform 3 below.

[0056] In this embodiment, by providing a bag-supporting mechanism, there is no need to manually support the bag during the soil filling process, which can reduce manual labor consumption and the workers do not need to face great safety hazards.

[0057] The specific working process of the device of the present invention is as follows:

[0058] Fix the ton bag on the support platform 3 through the ton bag hook 11, and fix the sealing drawstring of the ton bag on the sealing hook 17. After adjusting the positions of various parts, start to load the soil mechanically. After the soil is loaded, the soil loading machine transfers to another ton bag for loading, and this ton bag waits for the transport vehicle to transport. When the transport vehicle reaches the specified range, start the automatic loading control switch 8, the hydraulic telescopic rod 6 is turned on, and the ton bag falls into the transport vehicle; at the same time, the automatic unhooking device of the bag support mechanism is started to automatically unhook the ton bag hook 11; the sealing device is started for automatic sealing. After the transport vehicle leaves, the hydraulic telescopic rod 6 is closed and enters the next cycle.

[0059] The device for loading ton bags of soil for cofferdam filling of the present invention has the following advantages:

[0060] (1) The present invention aims to solve the problems of efficiency, safety and cost in the construction of cofferdams in water conservancy and hydropower projects. The device consists of an upper structure and a lower structure. The upper structure includes a bag-supporting and unhooking part and an automatic sealing part. The lower structure includes a load-bearing mechanism and a telescopic support mechanism. Through the coordinated work of various components, a series of automated operations such as fixing the ton bag, filling the bag with soil, unhooking, sealing and loading the bag can be realized.

[0061] (2) In the present invention, the opening of the cover plate 301 of the support platform 3 is utilized to realize the linkage between the automatic unhooking of the bag holding mechanism and the automatic sealing, and the closing of the cover plate 301 is utilized to realize the restoration of the bag holding mechanism and the unhooking linkage of the sealing hook 17 of the automatic sealing part, thereby ensuring that the bag holding, unhooking and sealing actions can be completed synchronously when the hydraulic telescopic rod 6 is opened, without adding other power devices.
