Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation grouting, in particular to a pile foundation grouting device for infrastructure engineering. Background Art

[0002] Infrastructure projects are infrastructure construction projects, and during infrastructure projects, pile foundation grouting is often required. Pile foundation grouting is a construction technology used to improve the performance of pile foundations. It is done by injecting cement slurry or other chemical slurry into the bottom or side of the pile to fill the gaps between the bottom and side of the pile, thereby improving the adhesion and friction between the pile and the surrounding soil, thereby improving the bearing capacity and stability of the pile foundation. Grouting often requires the use of a grouting machine. While using the grouting machine, the staff can continuously add slurry to the grouting machine. However, the space inside the grouting machine is limited, and the grouting speed is limited. The staff's slurry addition speed may be faster than the grouting speed of the grouting machine.

[0003] A Chinese patent application CN202322100883.0 discloses a pile foundation grouting device for bridge construction. The key points of its technical solution are: the pile foundation grouting device for bridge construction can be fixed on the ground by adding a vehicle base, an electric telescopic rod, a No. 1 motor, a drill bit and a fixing plate, thereby increasing stability during grouting.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: a grouting machine is often required for grouting. When using the grouting machine, the staff can continuously add slurry to the grouting machine. However, the space in the grouting machine is limited, and the grouting speed is limited. When the staff uses the grouting machine for grouting operations, the grouting speed of the grouting machine is slow, and the speed at which the staff adds slurry to the grouting machine is faster than the grouting speed of the grouting machine, which causes the grouting machine to be quickly filled. The staff can only suspend adding material to the grouting machine, which causes problems affecting the work efficiency of the staff. Therefore, in response to the above problems, a pile foundation grouting device for infrastructure projects is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the grouting machine is quickly filled up and the staff can only stop adding materials to the grouting machine, thereby affecting the work efficiency of the staff, and to propose a pile foundation grouting device for infrastructure projects.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pile foundation grouting device for infrastructure engineering, including a grouting machine, a grouting pipe is installed in the grouting machine, a grouting port is slidably installed on the arc surface of the grouting pipe, an incremental device is provided on one side of the grouting machine, the incremental device includes a placing plate, the placing plate is fixedly connected to one side of the grouting machine, a sliding frame is fixedly connected to one side of the grouting machine, a sliding groove is provided on the upper surface of the sliding frame, an L-shaped frame is slidably connected to the inner surface of the sliding groove of the sliding frame, a round rod is fixedly connected to one side of the L-shaped frame, an incremental bin is fixedly connected to the upper surface of the grouting machine, and a blocking plate is slidably connected inside the incremental bin.

[0007] The effect achieved by the above components is: by setting the incremental device, the effect of expanding the slurry space of the grouting machine is achieved, which avoids the situation where the grouting speed of the grouting machine is slow when the staff uses the grouting machine for grouting operation, and the speed at which the staff adds slurry into the grouting machine is faster than the grouting speed of the grouting machine, which causes the grouting machine to be filled up quickly. The staff can only suspend adding materials to the grouting machine, thereby affecting the work efficiency of the staff, thereby improving the practicality of the device.

[0008] Preferably, one side of the L-shaped frame is fixedly connected to a fixing rod, the arc surface of the fixing rod is slidably connected to an operating plate, the side of the operating plate close to the L-shaped frame is fixedly connected to an insertion rod, and one side of the sliding frame is provided with two slots.

[0009] The effect achieved by the above components is: it achieves the effect of fixing and limiting the L-shaped frame, avoiding the grouting machine from shaking when working, causing the L-shaped frame to slide unconsciously in the slide groove of the sliding frame, thereby causing the incremental bin to shift.

[0010] Preferably, one end of the fixing rod away from the L-shaped frame is fixedly connected to the limiting plate, and the size of the insertion rod is adapted to the size of the sliding frame slot.

[0011] The effect achieved by the above components is that the limit plate limits the maximum sliding distance of the operating panel on the arc surface of the fixed rod, thereby preventing the operating panel from detaching from the arc surface of the fixed rod due to the strong pulling force when the staff pulls the operating panel.

[0012] Preferably, the arc surface of the fixing rod is sleeved with a first spring, and two ends of the first spring are fixedly connected to the operating plate and the L-shaped frame respectively.

[0013] The effects achieved by the above components are as follows: the first spring improves the stability of the insertion rod when limiting the L-shaped frame.

[0014] Preferably, one side of the incremental bin is fixedly connected to a screw, the arc surface of the screw is threadedly connected to a strip plate, and the strip plate is slidably connected to one side of the blocking plate.

[0015] The effect achieved by the above components is: it achieves the effect of limiting the blocking plate, avoiding the blocking plate from being displaced due to the inertia generated by pulling the incremental bin, causing the blocking plate to be forced to detach from the incremental bin, thereby causing the residual grouting in the incremental bin to spread.

[0016] Preferably, a disassembly device is provided on one side of the grouting port, and the disassembly device includes an insert plate, which is fixedly connected to one side of the grouting port, and the arc surface of the grouting pipe is fixedly connected to a connecting block, and the surface of the insert plate is slidably connected to the connecting block, and the upper surface of the connecting block is fixedly connected to an L-shaped plate, and a driving rod is inserted into the internal thread of the L-shaped plate, and one end of the driving rod is rotatably connected to the connecting block, and a connecting hole is opened on the surface of the insert plate.

[0017] The effect achieved by the above components is: by setting up a disassembly device, the grouting pipe and the grouting port can be quickly disassembled and separated to facilitate unblocking, avoiding too much grouting through the grouting pipe at the same time, and a lot of grouting accumulating into the grouting port. The size of the grouting port is small, which makes it difficult to meet the needs of a large amount of grouting being ejected at the same time, resulting in the grouting port being blocked, thereby affecting the normal grouting of the grouting machine, thereby improving the practicality of the device.

[0018] Preferably, a positioning rod is fixedly connected to one side of the connecting block close to the driving rod, and the arc surface of the positioning rod is slidably connected to the L-shaped plate.

[0019] The effect achieved by the above components is that the positioning rod limits the connection block from rotating with the driving rod, so that the staff can quickly and accurately insert the connection block into the connection hole of the plug board, thereby improving the stability of the device.

[0020] In summary, the beneficial effects of the present invention are as follows:

[0021] 1. In the utility model, by setting an increment device, the effect of expanding the slurry space of the grouting machine is achieved, which avoids the situation where the grouting speed of the grouting machine is slow when the staff uses the grouting machine for grouting operation, and the staff adds slurry into the grouting machine at a speed greater than the grouting speed of the grouting machine, which causes the grouting machine to be quickly filled up. The staff can only suspend adding material to the grouting machine, thereby causing a situation that affects the work efficiency of the staff, thereby improving the practicality of the device.

[0022] 2. In the utility model, by setting a disassembly device, the grouting pipe and the grouting port can be quickly disassembled and separated to facilitate unblocking, thereby avoiding the situation where too much grouting passes through the grouting pipe at the same time, and a large amount of grouting accumulates and enters the grouting port. The size of the grouting port is small, which makes it difficult to meet the needs of a large amount of grouting to be ejected at the same time, resulting in the grouting port being blocked, thereby affecting the normal grouting of the grouting machine, thereby improving the practicality of the device.

By setting the increment device 4, the effect of expanding the slurry space of the grouting machine 1 is achieved, which avoids the situation that when the staff uses the grouting machine 1 to perform grouting operation, the grouting speed of the grouting machine 1 is slow, and the staff adds slurry into the grouting machine 1 at a speed greater than the grouting speed of the grouting machine 1, thereby causing the grouting machine 1 to be quickly filled, and the staff The staff can only suspend adding materials to the grouting machine 1, which affects the work efficiency of the staff, thereby improving the practicality of the device. A disassembly device 5 is provided on one side of the grouting port 3. By setting the disassembly device 5, the grouting pipe 2 and the grouting port 3 can be quickly disassembled and separated to facilitate unblocking, avoiding the situation where too much grouting passes through the grouting pipe 2 at the same time, and more grouting accumulates and enters the grouting port 3. The size of the grouting port 3 is small, and it is difficult to meet the needs of a large amount of grouting being ejected at the same time, resulting in the grouting port 3 being blocked, thereby affecting the normal grouting of the grouting machine 1, thereby improving the practicality of the device.

[0030] The specific settings and functions of the increment device 4 and the disassembly device 5 are described in detail below.

[0031] Reference Figure 2 、 Figure 3 and Figure 4As shown, in this embodiment: the incremental device 4 includes a placing plate 401, the placing plate 401 is fixedly connected to one side of the grouting machine 1, a sliding frame 402 is fixedly connected to one side of the grouting machine 1, the upper surface of the sliding frame 402 is provided with a slide groove, the inner surface of the slide groove of the sliding frame 402 is slidably connected to an L-shaped frame 403, one side of the L-shaped frame 403 is fixedly connected to a round rod 404, the end of the round rod 404 away from the L-shaped frame 403 is fixedly connected to an incremental bin 405, the incremental bin 405 is slidably connected to the upper surface of the grouting machine 1, a blocking plate 406 is slidably connected in the incremental bin 405, one side of the L-shaped frame 403 is fixedly connected to a fixed rod 407, the arc surface of the fixed rod 407 is slidably connected to an operating plate 408, and the operating plate 408 is fixed to one side of the L-shaped frame 403. The fixed connection is provided with an insertion rod 409, and one side of the sliding frame 402 has two slots. When the staff needs to increase the slurry placement space for the grouting machine 1, they pull the operating plate 408 to make the operating plate 408 slide on the arc surface of the fixed rod 407, and at the same time, the operating plate 408 drives the insertion rod 409 to move until the insertion rod 409 is disengaged from the slot of the sliding frame 402. At this time, the L-shaped frame 403 is pulled to make the L-shaped frame 403 slide in the slide groove of the sliding frame 402, and at the same time, the L-shaped frame 403 drives the round rod 404 to move, and the round rod 404 drives the incremental bin 405 to move until the incremental bin 405 slides from the surface of the placement plate 401 to the grouting machine 1, until the incremental bin 405 is aligned with the grouting machine 1, and then press the operating plate 408 to make the operating plate 408 on the fixed rod 40 7 slides on the arc surface, and the operating plate 408 drives the insertion rod 409 to move until the insertion rod 409 is inserted into the slot of the sliding frame 402. At this time, the L-shaped frame 403 is fixed and limited, avoiding the grouting machine 1 from shaking when working, causing the L-shaped frame 403 to slide unconsciously in the slide groove of the sliding frame 402, thereby causing the incremental bin 405 to shift. The end of the fixed rod 407 away from the L-shaped frame 403 is fixedly connected to the limiting plate 410, and the size of the insertion rod 409 is adapted to the size of the slot of the sliding frame 402. When the staff pulls the operating plate 408, the operating plate 408 slides on the arc surface of the fixed rod 407. At this time, the limiting plate 410 limits the sliding of the operating plate 408 on the arc surface of the fixed rod 407 The effect of the maximum distance prevents the operating plate 408 from being separated from the arc surface of the fixed rod 407 due to the large pulling force when the staff pulls the operating plate 408. The arc surface of the fixed rod 407 is covered with a first spring 411, and the two ends of the first spring 411 are fixedly connected to the operating plate 408 and the L-shaped frame 403 respectively. When the staff releases the operating plate 408, the rebound force of the first spring 411 drives the operating plate 408 to slide on the arc surface of the fixed rod 407. At the same time, the operating plate 408 drives the insertion rod 409 to move until the insertion rod 409 is inserted into the slot of the sliding frame 402. At this time, the first spring 411 improves the stability of the insertion rod 409 when limiting the L-shaped frame 403. A screw 412 is fixedly connected to one side of the incremental bin 405.The arc surface of the screw 412 is threadedly connected to a strip plate 413, which is slidably connected to one side of the blocking plate 406. When the staff no longer uses the incremental bin 405, the incremental bin 405 is moved onto the placement plate 401 and the blocking plate 406 is pushed to slide in the incremental bin 405 until the blocking plate 406 blocks the space in the incremental bin 405. At this time, the strip plate 413 is rotated to make the strip plate 413 move along the arc surface of the screw 412 until the strip plate 413 blocks the blocking plate 406. At this time, the blocking plate 406 is limited, avoiding the blocking plate 406 from being displaced due to the inertia generated by pulling the incremental bin 405, resulting in the blocking plate 406 being forced to detach from the incremental bin 405, thereby causing the residual grouting in the incremental bin 405 to spread.

[0032] Reference Figure 2 and Figure 5 When the operator rotates the driving rod 54, the driving rod 54 moves in the internal thread of the L-shaped plate 53, and the driving rod 54 drives the connecting block 55 to move, and the connecting block 55 drives the positioning rod 56 to slide in the L-shaped plate 53. At this time, the positioning rod 56 achieves the effect of limiting the connection block 55 to follow the rotation of the driving rod 54, so that the operator can quickly and accurately insert the connection block 55 into the connection hole of the driving plate 51, thereby improving the stability of the device.

[0033] Working principle: when the staff needs to use the incremental bin 405 to increment the grouting machine 1, they pull the operating plate 408 to make the operating plate 408 slide on the arc surface of the fixed rod 407, the first spring 411 is stretched, and the operating plate 408 drives the insertion rod 409 to move until the insertion rod 409 disengages from the slot of the sliding frame 402. At this time, the L-shaped frame 403 is pulled to make the L-shaped frame 403 slide in the slide groove of the sliding frame 402, and the L-shaped frame 403 drives the round rod 404 to move, and the round rod 404 drives the incremental bin 405 to move until the incremental bin 405 slides from the surface of the placing plate 401 to the grouting machine 1 until the incremental bin 405 is aligned with the grouting machine 1. At this time, the operating plate 408 is released, and the rebound force of the first spring 411 drives the operating plate 408 to slide on the arc surface of the fixed rod 407. At the same time, the operating plate 408 drives the insertion rod 409 to move. The slurry in the incremental bin 405 is no longer blocked by the blocking plate 406, and the slurry in the incremental bin 405 is no longer blocked by the blocking plate 406. At this time, the slurry space of the grouting machine 1 is expanded, thereby avoiding the situation that the grouting speed of the grouting machine 1 is slow when the staff uses the grouting machine 1 for grouting operation, and the staff adds slurry to the grouting machine 1 at a speed greater than the grouting speed of the grouting machine 1, which causes the grouting machine 1 to be filled up quickly. The staff can only suspend the addition of materials to the grouting machine 1, thereby affecting the work efficiency of the staff and improving the practicality of the device.

[0034] When the grouting port 3 is unplugged, the driving rod 54 is rotated, and the driving rod 54 is threaded in the L-shaped plate 53, and the driving rod 54 drives the connecting block 55 to move, and the connecting block 55 drives the positioning rod 56 to slide in the L-shaped plate 53 until the connecting block 55 is disengaged from the connecting hole of the plug plate 51. At this time, the grouting port 3 is pulled to make the grouting port 3 slide on the arc surface of the grouting pipe 2, and the grouting port 3 drives the plug plate 51 to move until the plug plate 51 is disengaged from the connecting block 52. At this time, the slurry accumulated in the grouting port 3 can be poured back into the grouting machine 1. At this time, the grouting pipe 2 and the grouting port 3 are quickly disassembled and separated, and the grouting port 3 is convenient for unplugging, avoiding too much grouting through the grouting pipe 2 at the same time. More grouting accumulates into the grouting port 3. The size of the grouting port 3 is small, which is difficult to meet the needs of a large amount of grouting at the same time.
