Description

Technical Field

[0001] This application relates to the technical field of flood control and emergency rescue equipment, and particularly to a reinforcement device for flood control and emergency rescue in high-density old urban areas during floods. Background Art

[0002] In high-density old urban areas, in the face of floods, due to the dense structure of the city, areas such as dams and low-lying areas are vulnerable to the impact and backflow risk of floods. Emergency rescue personnel need to use flood control and emergency rescue equipment to reinforce dams, build temporary water barriers, or fix flood control facilities to increase the protection intensity, reduce the invasion of floods into the urban area, ensure the safety of people and property, and respond to possible sudden floods.

[0003] Among them, pile driving operation is a key step in reinforcing dams, low-lying areas, or flood-prone areas. Emergency rescue personnel usually drive pile columns through a pile driver, aiming to enhance the stability of the dam and support waterproof materials such as water baffle plates and waterproof cloths to quickly form a barrier to prevent flood backflow and slow down the inflow speed of floods.

[0004] In this process, the operator of a handheld pile driver cannot ensure the stability of the pile column only by hand feeling, resulting in the pile column being prone to large tilts, affecting the pile driving effect, reducing the stability of the entire flood control barrier, and thus affecting the progress of the emergency rescue work.

[0005] Although a telescopic support can provide support for the pile column to ensure its verticality and stability, ordinary telescopic supports often have problems of insufficient or excessive sliding friction. If the sliding friction of the support is small, when the operator drives the pile column, the support may not provide enough supporting force, resulting in the pile column tilting or being unable to be firmly fixed; if the sliding friction is too large, the support may not be able to contract quickly due to excessive friction, which will affect the telescopic function of the support, unable to quickly adapt to the support requirements of pile columns of different heights, thus affecting the subsequent pile driving work, further reducing the emergency rescue efficiency, and affecting the integrity of the flood control barrier and urban safety. Summary of the Invention

[0006] This application proposes a reinforcement device for flood control and emergency rescue in high-density old urban areas during floods, which has the advantages of being able to stably support the pile column, preventing unstable conditions such as tilting and offset of the pile column, and being able to quickly contract or extend according to the usage requirements without affecting the pile driving efficiency, ensuring the smooth progress of the flood control work, and thus quickly and efficiently constructing a flood control barrier, so as to solve the problems of reduced emergency rescue efficiency and reduced construction efficiency and quality of the flood control barrier caused by the uncontrollable sliding friction of the telescopic support when driving piles with a handheld pile driver.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a reinforcement device for flood prevention and rescue in flood disasters in high-density old urban areas, including a support plate for being mounted on the outside of a pile column to support the pile column, two cylinder bodies are symmetrically and movably installed at the bottom of both ends of the support plate, and the interior of the cylinder body is filled with a hydraulic medium, a piston is slidably installed on the inner wall of the cylinder body, a piston rod is fixedly installed on the top of the piston, an installation groove is provided inside the piston rod, and an adjusting rod is threadedly connected on the inner wall of the installation groove. When piling is carried out, the flow speed of the hydraulic medium on both sides of the piston inside the cylinder body can be controlled by changing the position of the adjusting rod, thereby adjusting the sliding speed of the piston rod, so that the downward movement speed of the pile column during piling is adapted to the sliding speed of the piston rod.

[0008] Furthermore, a main through hole is opened at the axis of the piston, and multiple groups of secondary through holes are opened at the end of the piston rod close to the piston. Each group of secondary through holes is provided with multiple, and the main through hole is connected or blocked with each secondary through hole to adjust the flow rate of the hydraulic medium.

[0009] Furthermore, a fixing ring is fixedly installed on the outer side of the top end of the piston rod, and two support rods are symmetrically fixedly installed on the outer side of the fixing ring. A connecting rod is commonly fixedly installed on one end of the two support rods away from the fixing ring, and the connecting rod is hinged to the support plate.

[0010] Furthermore, a plurality of grooves distributed in a circular array are provided on the outer side of the top end of the adjusting rod, so that the user can rotate the adjusting rod through the grooves.

[0011] Furthermore, a support hole is provided on the support plate, and a limiting mechanism is provided on the inner side wall of the support hole for adapting to piles of different sizes.

[0012] Furthermore, the limiting mechanism includes a screw threadedly connected to the side wall of the support plate, one end of the screw close to the support hole is rotatably mounted on the limiting plate, and the end of the screw away from the limiting plate is fixedly mounted with a rotating handle.

[0013] Furthermore, a fixing plate is rotatably mounted on the bottom end of the cylinder body, a connecting shaft is fixedly mounted on the fixing plate, a bottom plate is rotatably mounted on the outer side of the connecting shaft, and the bottom plate is sleeved on the outer side of the fixing plate.

[0014] The beneficial effects of the present invention are as follows:

[0015] A reinforcement device for flood control and emergency rescue in high-density old urban areas provided by the present application. When driving piles, the user can rotate the adjusting rod according to the ground environment to adjust its position, thereby controlling the number of auxiliary through holes communicated with the main through hole, adjusting the flow rate of the hydraulic medium inside the cylinder, so that the downward movement speed of the pile column during pile driving by the pile driver can be adapted to the sliding speed of the piston rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1 to 5 , a reinforcement device for flood control and emergency rescue in high-density old urban areas, including a support plate 1 for sleeving outside a pile column to support the pile column. A support hole 12 is provided on the support plate 1, and a limiting mechanism is arranged on the inner side wall of the support hole 12 for adapting to pile columns of different sizes. In this embodiment, the limiting mechanism includes a screw rod 13 threadedly connected to the side wall of the support plate 1. One end of the screw rod 13 close to the support hole 12 is rotatably installed with a limiting plate 14, and a rotating handle 15 is fixedly installed at the end of the screw rod 13 away from the limiting plate 14. When using the support plate 1 to support pile columns of different diameters, the screw rod 13 is rotated by driving the rotating handle 15, so that the limiting plate 14 fits against the outside of the pile column, fixing the support plate 1 to the pile column. The limiting mechanism can also be composed of other structures with telescopic effects, such as an airbag that can be inflated through an air inflation pump and a deflation valve, or a slider can be driven by a left-handed and right-handed screw rod to clamp pile columns of different sizes.

[0025] Refer to Figure 2 , connecting rods 10 are symmetrically hinged on both sides of the support plate 1. Two support rods 9 are symmetrically and fixedly installed at the bottom of the connecting rods 10. A fixing ring 8 is fixedly installed at the end of the two support rods 9 away from the connecting rods 10. A cylinder body 2 is arranged at the bottom of the fixing ring 8. The inside of the cylinder body 2 is filled with a hydraulic medium. The bottom end of the cylinder body 2 is rotatably installed with a fixing plate 16. The fixing plate 16 is rotatably connected to the bottom plate 18 through a connecting shaft 17. The fixing plate 16 can rotate relative to the cylinder body 2 and the bottom plate 18 can rotate, so that the bottom plate 18 can still fit against the ground when the ground is uneven, supporting the support plate 1, the cylinder body 2, etc., and thus adapting to different ground environments.

[0026] Refer to Figures 2 to 4, a piston 3 is slidably installed inside the cylinder block 2. A piston rod 4 is fixedly installed at the top of the piston 3. One end of the piston rod 4 away from the piston 3 penetrates the cylinder block 2 airtightly, and a fixing ring 8 is fixedly installed on the outer side of the end of the piston rod 4 away from the piston 3. An installation groove is formed inside the piston rod 4, and an adjusting rod 5 is threadedly installed inside the installation groove. A plurality of grooves 11 are formed on the outer side of the top end of the adjusting rod 5, which is convenient for the operator to rotate the adjusting rod 5. A main through hole 6 is formed at the axis of the piston 3. A plurality of groups of secondary through holes 7 are formed at one end of the piston rod 4 close to the piston 3. Each group of secondary through holes 7 has a plurality of them. The main through hole 6 is connected or blocked with the secondary through holes 7, providing a flow channel for the hydraulic medium inside the cylinder block 2. And the height of the plurality of groups of secondary through holes 7 in the vertical direction is equal to the distance between the top wall of the adjusting rod 5 and the connecting rod 10, so that the connecting rod 10 will not affect the connection rate between the main through hole 6 and the secondary through holes 7.

[0027] When the cylinder block 2 and the piston rod 4 are not needed, the bottom wall of the adjusting rod 5 fits against the top wall of the main through hole 6, and the bottom wall of the main through hole 6 also fits against the inner bottom wall of the cylinder block 2. When it is necessary to use the pile driver to drive a pile, the support plate 1 is sleeved on the outside of the pile column. First, rotate the adjusting rod 5 to release the blockage of the bottom end of the adjusting rod 5 on the plurality of groups of secondary through holes 7, and pull the piston rod 4 upward. At this time, all the secondary through holes 7 are connected with the main through hole 6, and the hydraulic medium inside the cylinder block 2 can flow quickly through the main through hole 6 and the secondary through holes 7. Thus, the user can quickly move the piston rod 4 out according to the height of the pile column, so that the support plate 1 matches the length of the pile column. After determining the extending position of the piston rod 4, the operator can rotate the adjusting rod 5 in the reverse direction to make the adjusting rod 5 move downward to block some of the secondary through holes 7 and reduce the flow rate of the hydraulic medium inside the cylinder block 2. The moving distance of the adjusting rod 5 can be determined by the hardness of the ground. For a relatively soft piling environment, the piling resistance is small and the piling speed is relatively fast, so a faster sliding speed of the piston rod 4 is also required. Therefore, the downward moving distance of the adjusting rod is short; on the contrary, for a relatively hard piling environment, a slower sliding speed of the piston rod 4 is required, so the downward moving distance of the adjusting rod 5 is long. After the current pile column is completed, before driving the next pile column, the position of the adjusting rod 5 can also be controlled to quickly slide the piston rod 4 to adapt to the piling requirements. By changing the position of the adjusting rod 5, the number of secondary through holes 7 connected with the main through hole 6 is controlled, and then the flow rate of the hydraulic medium inside the cylinder block 2 is controlled, so that the sliding speed of the piston rod 4 can match the descending speed of the pile column. Thus, the support plate 1, the cylinder block 2 and the piston rod 4 can stably support the pile column during the piling process, prevent the pile column from tilting, and can also be quickly retracted or extended according to the use requirements without affecting the piling efficiency, and quickly and efficiently build a flood control barrier.

[0028] Working principle:

[0029] When the user needs to use the pile driver to drive piles, first put the support plate 1 on the outside of the pile column, and adjust the position of the limit plate 14 by rotating the screw 13 to clamp the pile column. When driving the pile, the user can first screw the adjusting rod 5 upwards until the top wall of the adjusting rod 5 contacts the bottom of the connecting rod 10, so that all the secondary through holes 7 are connected to the main through hole 6. Then, according to the ground environment, quickly slide the piston rod 4 to a suitable position, and then rotate the adjusting rod 5 in the reverse direction, so that the adjusting rod 5 moves downwards to block some of the secondary through holes 7, so that the downward movement speed of the pile column during pile driving can match the sliding speed of the piston rod 4. The adjusting rod 5 threadedly connected to the piston rod 4 makes it difficult for the adjusting rod 5 to slide during pile driving. Thus, the support plate 1, the cylinder block 2, the piston rod 4, etc. can not only stably support the pile column, prevent the pile column from tilting, deviating and other unstable conditions, ensure that the pile column maintains a vertical and stable posture, lay a solid foundation for the stability of the entire flood control facility, but also quickly contract or extend according to the use requirements without affecting the pile driving efficiency. The operator can complete the pile driving work more quickly without too much pause and adjustment, improve the work efficiency of the rescue personnel, and ensure that the flood control work can be carried out efficiently and smoothly, so as to quickly and efficiently build a solid flood control barrier.
