Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy project construction equipment, and in particular relates to a grabbing machine for water conservancy project anti-seepage wall construction and a construction method thereof. Background Art

[0002] The anti-seepage wall in water conservancy projects is a kind of barrier set up to prevent water penetration, protect the stability of the project structure and prolong its service life. The grouting anti-seepage wall is formed by injecting a special slurry into the foundation, allowing it to penetrate into the soil gaps and solidify to form a continuous anti-seepage layer. To form a grouting anti-seepage wall, it is first necessary to dig holes in the land. The traditional way of digging holes is to dig pits manually, which is time-consuming and labor-intensive, and the labor cost required is high. Therefore, the way of digging holes needs to be improved. Summary of the invention

[0003] The purpose of the present invention is to provide a grabbing machine and a construction method for the construction of anti-seepage walls of water conservancy projects in order to solve the above-mentioned technical problems. With the help of mechanized grabbing, the efficiency of digging and hole making is improved and the labor intensity of workers is reduced.

[0004] In view of this, the present invention provides a grabbing machine for construction of an anti-seepage wall of a water conservancy project, comprising:

[0005] The punching and grabbing head includes a movable seat and a plurality of movable shovel claws, the plurality of movable shovel claws are spaced apart along the circumference of the movable seat, the lower ends of the plurality of movable shovel claws jointly form a material grabbing cavity, the lower ends of the plurality of movable shovel claws can swing outward to open the material grabbing cavity, and the lower ends of the plurality of movable shovel claws can swing inward to close the material grabbing cavity;

[0006] A counterweight is vertically movably connected to the movable seat, and when the counterweight moves vertically downward, it can drive the lower ends of the multiple movable shovel claws to swing outward, and when the counterweight moves vertically upward, it can drive the lower ends of the multiple movable shovel claws to swing inward;

[0007] A fixed seat, which is arranged above the movable seat, and the movable seat is vertically movably connected to the fixed seat;

[0010] In this technical solution, the grab machine is placed at the location where digging is required on the construction site. The bottom surface of the support frame contacts the ground to support the grab machine as a whole. The lifting component moves the grab head and the counterweight close to the fixed seat. At this time, the grab cavity is in a closed state. The lifting component releases the grab head and the counterweight. During this process, the grab head and the counterweight will move downward under the action of gravity, and the counterweight will move vertically downward relative to the grab head, so that the grab cavity is opened. At this time, the bottoms of the multiple movable shovel claws are facing downward and can be inserted into the soil, allowing a large amount of soil to enter the grab cavity. The grabbing cavity is formed by the impact of the impactor and the counterweight is lifted up. Then the lifting assembly lifts the grabbing head and the counterweight upward. During this process, the counterweight first moves vertically upward, causing multiple movable shovel claws to swing inward, closing the grabbing cavity and allowing more soil to remain in the grabbing cavity. After the grabbing cavity is closed, the vertical upward movement of the counterweight will drive the grabbing head to move vertically upward together, so that the soil in the grabbing cavity is lifted up. At this time, the soil can be released to a suitable position to complete a digging. Then the lifting assembly continues to release the grabbing head and the counterweight, and lift the grabbing head and the counterweight to perform repeated digging.

[0024] In the above technical solution, further, a contact block is provided on the swing seat, and the pop-up member can slide in a direction perpendicular to the swing of the swing seat. The pop-up member includes an inclined section, which contacts the contact block. A spring is provided in the assembly groove, and both ends of the spring are respectively connected to the second end of the swing seat and the side wall of the assembly groove.

[0025] In the above technical solution, further, the pop-up member and the locking member both move in the vertical direction, the upper end of the pop-up member and the upper end of the locking member are connected to the same connecting seat, the upper end of the connecting seat extends out of the disassembly and assembly seat and is connected to a force ring; the pop-up member also includes a parallel section, the parallel section and the inclined section have a smooth transition, and the contact block can move between the parallel section and the inclined section.

[0026] The present invention also discloses a construction method suitable for the above-mentioned impact grab machine based on the construction of a water conservancy project anti-seepage wall, and the construction method comprises the following steps:

[0027] X1. Frame construction: Assemble the support frame, fixing seat and lifting components;

[0028] X2. Construction of the punching and grabbing head: Connect the guide disassembly and assembly assembly with the movable seat, control the locking part to unlock the positioning mechanism, control the pop-up part to adjust the positioning mechanism to the exit slot position, put the counterweight between the multiple movable shovel claws, extend the installation column at the upper end of the counterweight into the installation slot so that the slot and the positioning mechanism are opposite to each other, at this time the positioning mechanism is inserted into the slot, and the locking part locks the positioning mechanism in the current position, completing the installation of the upper end of the counterweight; then connect the connecting rods on the multiple movable shovel claws to the bottom of the counterweight in turn, completing the installation of the lower end of the counterweight;

[0029] X3. Overall assembly: Pass the lifting assembly through the fixing seat and connect it to the guide disassembly assembly;

[0030] X4. Lowering the grab: The lifting assembly releases the grab head, which moves downward under the gravity of the counterweight and drives multiple movable claws to swing outward to open the grab cavity, and finally the lower end of the movable claw is inserted into the soil;

[0031] X5. Pull up and grab the soil: The lifting component lifts the counterweight vertically. During the lifting process, the counterweight moves vertically upward to first drive multiple movable shovel claws to swing inward to close the grabbing cavity and temporarily store the soil in the grabbing cavity. During this process, the movable seat does not move. Then the counterweight continues to move vertically upward and moves vertically upward with the movable seat to transport the soil upward and release it to the appropriate position;

[0032] Repeat step X4 and step X5.

[0033] The beneficial effects of the present invention are:

[0034] 1. Through the cooperation of the support frame, the fixed seat, the punching and grabbing head, the counterweight and the lifting assembly, the punching and grabbing head is composed of a movable seat and a plurality of movable shovel claws, the plurality of movable shovel claws form a grabbing cavity, and the vertical movement of the counterweight drives the plurality of movable shovel claws to swing open and close the grabbing cavity, so that repeated excavation and hole making can be carried out by repeatedly relying on the action of gravity and the lifting action of the lifting assembly, which can reduce the labor intensity of workers and improve the efficiency of excavation and hole making.

[0035] 2. By designing the lifting component into a rope body and a winding mechanism, after the soil is lifted, the impact grab head can move sideways a certain distance, which is convenient for stacking and disposal of the excavated soil.

[0036] 3. By setting up a guide disassembly and assembly component to connect the counterweight and the lifting component, the disassembly and assembly of the counterweight is facilitated, and the guide disassembly and assembly component can also limit and guide the movement between the counterweight and the movable seat, thereby improving the stability of the counterweight during vertical movement relative to the movable seat.

[0037] 4. By arranging a mounting column and multiple slots at the upper end of the counterweight, the guide disassembly and assembly assembly is designed into two parts: a guide mechanism and a quick disassembly and assembly mechanism; the quick disassembly and assembly mechanism is designed to be a combination of a disassembly and assembly seat, a mounting slot, multiple groups of locking mechanisms, a locking piece, and a pop-up piece. In this way, when the mounting column on the counterweight is extended into the mounting slot, multiple groups of locking mechanisms are simultaneously inserted into multiple slots to lock the mounting column in the mounting slot. At the same time, the locking mechanism is locked in the current position by the locking piece, thereby improving the connection stability between the counterweight and the quick disassembly and assembly mechanism. When it is necessary to separate the counterweight from the quick disassembly and assembly mechanism, first control the locking piece to unlock the locking mechanism, and then control the pop-up piece to push the locking mechanism out of the slot, so that the mounting column can be directly withdrawn from the mounting slot, and the counterweight is easy to disassemble.

[0038] 5. By designing the locking mechanism as a combination of a swing seat, a locking groove, a contact block, and a spring, the pop-up piece includes an inclined section that contacts the contact block. In this way, when the first end of the swing seat enters the installation groove and is stuck in the slot, the locking piece can be stuck in the locking groove to lock the movement of the swing seat. After the locking piece is withdrawn from the locking groove, the swing seat can swing freely, and the locking and unlocking process is simple and stable; when the swing seat is unlocked, the pop-up piece is slid in one direction to make the contact point between the contact block and the pop-up piece move on the inclined section, which can push the first end of the swing seat to withdraw from the installation groove and squeeze the spring, at which time the installation column can withdraw from the installation groove; the pop-up piece is slid in the other direction to make a short gap between the contact block and the pop-up piece, and the elastic force of the spring makes the contact block always contact with the pop-up piece. In this process, the first end of the swing seat can be pushed into the installation groove by the spring and stuck in the slot. In this way, the disassembly and assembly between the counterweight and the quick disassembly and assembly mechanism can be controlled by sliding the pop-up piece, which is easy to operate.

[0039] 6. By designing both the pop-up piece and the locking piece to move in the vertical direction, and connecting the locking piece and the pop-up piece at the same time through a connecting seat, and extending the upper end of the connecting seat out of the disassembly and assembly seat and then connecting the force ring, the connecting seats in multiple sets of locking mechanisms can be connected to the same force ring, and applying external force to the force ring can simultaneously control the multiple sets of locking mechanisms to enter and exit the corresponding slots, making the operation simpler and more efficient; in addition, the force ring is arranged outside the disassembly and assembly seat and is easy to observe. The position status of the locking piece and the pop-up piece can be judged by the position of the force ring, which is convenient for observing whether there is any abnormal coordination between each locking mechanism and the corresponding locking piece and pop-up piece.

[0059] like Figure 1-Figure 5 As shown, the embodiment of the present application provides a grabbing machine for construction of water conservancy project anti-seepage wall, including: a grabbing head 1, a counterweight 2, a fixing seat 3, a support frame 4, a lifting assembly,

[0060] See also Figure 1 and Figure 2The punching and grabbing head 1 includes a movable seat 101 and a plurality of movable shovel claws 102, the plurality of movable shovel claws 102 are spaced apart along the circumference of the movable seat 101, the lower ends of the plurality of movable shovel claws 102 jointly form a material grabbing cavity, the lower ends of the plurality of movable shovel claws 102 can swing outward to open the material grabbing cavity, and the lower ends of the plurality of movable shovel claws 102 can swing inward to close the material grabbing cavity; in this embodiment, the movable shovel claw 102 includes a movable rod 1021 and a shovel head 1022, the upper end of the movable rod 1021 is rotated with the movable seat 101 The movable connection allows the lower end of the movable rod 1021 to swing inward and outward relative to the movable seat 101, and the lower end of the movable rod 1021 is rotatably connected to the upper end of the shovel head 1022, so that the entire shovel head 1022 can swing inward and outward relative to the movable rod 1021. The upper end of the shovel head 1022 is provided with a connecting rod 1023, and the end of the connecting rod 1023 away from the shovel head 1022 is rotatably connected to the counterweight 2, and the lower end of the shovel head 1022 is pointed, which is convenient for the shovel head 1022 to be inserted into the soil.

[0061] The counterweight 2 is vertically movably connected to the movable seat 101. The mass of the counterweight 2 is greater than the mass of the punching and grabbing head 1. When the counterweight 2 moves vertically downward, it can drive the connecting rod 1023 on each shovel head 1022 to swing downward, thereby driving the lower ends of multiple movable shovel claws 102 to swing outward at the same time. When the counterweight 2 moves vertically upward, it can drive the connecting rod 1023 on each shovel head 1022 to swing upward, thereby driving the lower ends of multiple movable shovel claws 102 to swing inward at the same time.

[0062] The fixed seat 3 is arranged above the movable seat 101, and the movable seat 101 is vertically movably connected with the fixed seat 3; the support frame 4 is used to support the fixed seat 3, and the fixed seat 3 cooperates with the lifting assembly to limit and guide the vertical movement of the impact grab head 1;

[0063] The lifting assembly is used to vertically lift the counterweight 2 and the grab head 1 respectively. In this embodiment, the lifting assembly specifically includes: a rope body 5, a winding mechanism 6,

[0064] See also Figure 1 The first end of the rope body 5 passes through the fixed seat 3 and the movable seat 101 in sequence and is connected to the counterweight 2. In this embodiment, the rope body 5 is generally made of a material with higher strength, such as a metal wire material;

[0065] See also Figure 3 The reeling mechanism 6 is connected to the second end of the rope 5, and the reeling mechanism 6 can reel in and release the rope 5. Any structure in the prior art that can reel in and release the rope 5 can be used as the reeling mechanism 6 in this embodiment;

[0066] In this embodiment, when the rope body 5 moves upward, it will first drive the counterweight 2 to move upward. Since the counterweight 2 and the movable seat 101 can move relatively, the movable seat 101 will not move upward with the counterweight 2 in the initial period of time. During this process, the counterweight 2 simultaneously drives the lower ends of the multiple movable shovel claws 102 to swing inward to close the material grabbing cavity. When the material grabbing cavity is closed, the connecting rod 1023 cannot continue to swing upward. At this time, the counterweight 2 can drive the movable seat 101 to move upward through the connecting rod 1023 and the movable rod 1021, so that the entire punching and grabbing head 1 moves upward.

[0067] Figure 5 The schematic diagram shown is a closed state of the grabbing chamber. At this time, the rope body 5 continues to pull the counterweight 2 upward, and the entire grabbing head 1 will move upward;

[0068] When the grab head 1 is at a higher position, the material grabbing cavity is in a closed state. At this time, the winding mechanism 6 quickly releases the rope body 5, so that the counterweight 2 and the grab head 1 can move vertically downward under the action of gravity, and the counterweight 2 is subject to less air resistance, so the counterweight 2 will move downward relative to the grab head 1. In this process, the counterweight 2 simultaneously drives the lower ends of the multiple movable shovel claws 102 to swing outward to open the material grabbing cavity;

[0069] Figure 4 What is shown is a schematic diagram of the grab chamber in the open state, at this time, the counterweight 2 and the entire grab head 1 continue to move downward, and finally the lower ends of the movable shovel claws 102 will be inserted into the soil, allowing the soil to enter the grab chamber from the bottom of the grab head 1; then the rope body 5 lifts the counterweight 2 upward to close the grab chamber, so that a large amount of soil remains in the grab chamber, and after the grab chamber is closed, the vertical upward movement of the counterweight 2 will drive the grab head 1 to move vertically upward together, so that the soil in the grab chamber is lifted, and at this time the soil can be released to a suitable position to complete a digging, and then the lifting assembly continues to release the grab head 1 and the counterweight 2, and lift the grab head 1 and the counterweight 2 to perform repeated digging.

Fig.10, the two endpoints on the inclined section 1101 are defined as the first position and the second position, wherein the vertically higher position is the first position, and the vertically lower position is the second position. When the pop-up member 11 slides vertically upward, the contact point between the contact block 903 and the inclined section 1101 moves from the first position to the second position. During this process, the pop-up member 11 pushes the second end of the swing seat 901 toward the mounting groove 801 and squeezes the spring 904, so that the first end of the swing seat 901 withdraws from the mounting groove 801; when the pop-up member 11 slides vertically downward, the contact point between the contact block 903 and the inclined section 1101 moves from the second position to the first position. During this process, the elastic force of the spring 904 pushes the second end of the swing seat 901 away from the mounting groove 801, and keeps the contact block 903 in contact with the inclined section 1101 at all times, so that the first end of the swing seat 901 enters the mounting groove 801.

[0084] This embodiment provides a grabbing machine for construction of water conservancy project anti-seepage wall. In addition to the technical solutions of the above embodiments, the arrangement of the ejection member 11 and the locking member 10 is optimized.

[0085] See also Fig.12 and Fig.13 The ejection member 11 and the locking member 10 both move in the vertical direction. The upper end of the ejection member 11 and the upper end of the locking member 10 are connected to the same connection seat 12. Please refer to Fig. 9 The disassembly seat 8 is provided with a connecting groove for the connecting seat 12 to slide vertically, and the connecting groove penetrates the outer wall of the disassembly seat 8. The upper end of the connecting seat 12 extends out of the disassembly seat 8 and is connected to a force ring 13. By driving the force ring 13 to move vertically, the ejection member 11 and the locking member 10 can be driven to move vertically at the same time;

[0086] In this embodiment, the ejection member 11 further includes a parallel section 1102. Fig.13 The parallel section 1102 and the inclined section 1101 have a smooth transition, the contact block 903 can move between the parallel section 1102 and the inclined section 1101, and the length of the parallel section 1102 is greater than the length of the locking member 10 inserted into the locking groove 902;

[0087] See also Fig.12When the locking member 10 is inserted into the locking groove 902, the contact block 903 is released from the parallel section 1102. At this time, the connecting seat 12 is pulled upward, which can drive the locking member 10 and the pop-up member 11 to move upward at the same time. In the process of the locking member 10 withdrawing from the locking groove 902, the contact point of the contact block 903 and the pop-up member 11 moves downward on the parallel section 1102. When the locking member 10 is completely withdrawn from the locking groove 902, the contact point of the contact block 903 and the pop-up member 11 will be in contact with the first position of the inclined section 1101. If the ejection member 11 and the locking member 10 continue to move upward, the contact point between the contact block 903 and the inclined section 1101 moves from the first position to the second position, so that the first end of the swing seat 901 exits the card slot 202 and the installation slot 801. In this way, by pulling the connecting seat 12 upward, the swing seat 901 can be unlocked and the ejection member 11 can push the first end of the swing seat 901 out of the card slot 202, so as to facilitate the disassembly of the counterweight 2 and the quick disassembly mechanism 702.

[0088] When it is necessary to install the counterweight 2 and the quick disassembly mechanism 702, first make the contact point between the contact block 903 and the pop-up member 11 located at the second position of the inclined section 1101, then extend the installation column 201 into the installation slot 801, make the slot 202 and the locking mechanism 9 face each other, then push the connecting seat 12 downward, make the first end of the swinging seat 901 enter the installation slot 801 and snap into the slot 202, then continue to push the connecting seat 12 downward, make the locking member 10 snap into the locking slot 902, so that the installation of the counterweight 2 and the quick disassembly mechanism 702 can be completed by pushing the connecting seat 12 downward;

[0089] In this embodiment, all the connection seats 12 are connected to the same force ring 13, so that when the counterweight 2 and the quick disassembly mechanism 702 are disassembled, the worker only needs to apply force to the force ring 13 to control all the pop-up members 11 and the locking members 10 at the same time, and the operation is more efficient. In addition, the force ring 13 is arranged outside the disassembly seat 8, which is easy to observe. The position of the force ring 13 can be used to determine the position state of the locking member 10 and the pop-up member 11, so as to facilitate the observation of whether there is any abnormality in the matching between each locking mechanism 9 and the corresponding locking member 10 and the pop-up member 11;

[0090] See also Figure 6 The force ring 13 is located in the space formed between the guide column 7011 and the disassembly and assembly seat 8. During the excavation and hole-making operation, external objects are not likely to affect the force ring 13. The force ring 13, the connecting seat 12, the pop-up member 11, and the locking member 10 themselves also have a certain weight and are not easily bounced up by impact. When it is necessary to apply force to the force ring 13, workers can use tools such as crowbars to reach into the space between the guide column 7011 and the disassembly and assembly seat 8 to pull the force ring 13 upward and press it downward.

[0091] This embodiment provides a construction method based on the construction of a water conservancy project anti-seepage wall, which is applicable to the punching and grabbing machine in the above embodiment. The construction method includes the following steps:

[0092] X1. Frame construction: Assemble the support frame 4, the fixing seat 3 and the lifting assembly at a suitable position on the construction site, wherein the support frame 4 and the lifting assembly are placed on the ground. If the lifting assembly adopts the rope body 5 and the winding mechanism 6 in Example 1, the rope body 5 is first passed through the top of the support frame 4 and the fixing seat 3 before the support frame 4 is erected, and the winding mechanism 6 releases the rope body 5 to ensure that the rope body 5 is long enough to extend below the fixing seat 3, so as to facilitate the operation of the workers;

[0093] X2. Construction of the punching and grabbing head 1: Connect the guide disassembly assembly 7 with the movable seat 101, control the locking member 10 to unlock the positioning mechanism 9, control the pop-up member 11 to adjust the positioning mechanism 9 to the position of exiting the slot 202, place the counterweight 2 between the multiple movable shovel claws 102, extend the mounting column 201 at the upper end of the counterweight 2 into the mounting slot 801 so that the slot 202 and the positioning mechanism 9 are opposite to each other, at this time, the positioning mechanism 9 is inserted into the slot 202, and the locking member 10 locks the positioning mechanism 9 in the current position, completing the installation of the upper end of the counterweight 2; then, connect the connecting rods 1023 on the multiple movable shovel claws 102 to the bottom of the counterweight 2 in turn, completing the installation of the lower end of the counterweight 2;

[0094] X3. Overall assembly: After the lifting assembly passes through the fixing seat 3, it is connected to the guide disassembly assembly 7. If the lifting assembly adopts the rope body 5 and the winding mechanism 6 in Example 1, it is only necessary to connect the rope body 5 extending below the fixing seat 3 to the guide disassembly assembly 7;

[0095] X4. Lowering the grab: The lifting assembly releases the grab head 1, which moves downward under the gravity of the counterweight 2 and drives the multiple movable shovel claws 102 to swing outward to open the grab cavity, and finally the lower end of the movable shovel claw 102 is inserted into the soil;

[0096] X5. Pull up and grab the soil: The lifting assembly lifts the counterweight 2 vertically. During the lifting process, the counterweight 2 moves vertically upward and first drives the multiple movable shovel claws 102 to swing inward to close the grabbing cavity and temporarily store the soil in the grabbing cavity. During this process, the movable seat 101 does not move. Then the counterweight 2 continues to move vertically upward and moves vertically upward with the movable seat 101, transporting the soil upward and releasing it to a suitable position;

[0097] In this embodiment, after step X1 to step X3 are completed, the overall equipment is built, and then step X4 and step X5 are repeated until the required holes are dug;

[0098] In this embodiment, repeated digging and hole making can be performed by repeatedly relying on the effect of gravity and the lifting effect of the lifting assembly, which can reduce the labor intensity of workers and improve the efficiency of digging and hole making.

[0099] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
