[0003] At the manual hole digging construction site, the pile hole needs to be protected. This kind of safety protection is mainly reflected in three aspects. First, after the pile hole is completed on the same day, the pile hole needs to be protected. People are prohibited from approaching to prevent people from accidentally falling into the pile hole, especially safety accidents caused by poor visibility at night. Second, during the manual hole digging operation, the personnel above the pile hole are protected to prevent people from accidentally falling. However, the existing safety protection is mostly to add fences at the pile hole and place several templates at the pile hole for protection. This safety protection device is not firmly placed. When the pile hole is not working, it is impossible to prevent people from falling. When it rains, it will also cause a large amount of rainwater to flow in. Third, the protection of construction personnel in the pile hole. When digging manually, the working environment is mainly underground limited space operations. The safety risks during the construction process are mainly damage to the rigging when lifting the soil or objects falling from the hole and hitting objects. The main safety protection measures now are that construction personnel wear helmets and add half of the interception net in the pile hole. Its safety protection needs to be improved.
[0004] On this basis, the utility model provides a safety protection device for anti-sliding pile digging construction to solve the problem. Utility Model Content

DETAILED DESCRIPTION
[0026] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 5 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.
[0027] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.
[0028] A safety protection device for anti-slip pile digging construction includes a pile hole. The pile hole is divided into a rectangular hole, a square hole, a round hole, etc. according to the construction situation. The utility model takes a rectangular hole as an example for description. A lock mouth will be cast at the upper end of the pile hole during construction. A safety plate 1 is placed above the lock mouth. The safety plate 1 is a steel template or a wooden template. In order to better waterproof, a waterproof layer is preferably provided on the wooden template. Fences 2 are fixedly installed around the safety plate 1. The fence 2 on one side is a detachable fence. When not in operation, all fences 2 are fixedly installed. When in operation, the fence 2 on this side is disassembled for lifting operations. A warning light 3 is fixedly installed at the upper end of the fence 2, and the warning light 3 is connected to an external power supply. The warning light 3 is used to remind personnel. A plurality of construction holes 4 are opened on the safety plate 1. The number of the construction holes 4 is set according to the size of the construction. The size of the construction holes 4 can at least meet the passage of personnel and buckets. The construction holes 4 are connected to the construction plate 5 by rotation through hinges. The safety plate 1 is connected to the limit plate 6 on all sides by rotation through hinges. A limit spring is sleeved on the hinge. The initial position of the limit spring makes the limit plate 6 and the safety plate 1 maintain a vertical inward tilt, so that the limit plate 6 maintains a certain pressing force on the side wall of the lock, but can be turned over by force.
[0029] The safety plate 1 is placed on the concrete lock mouth, and the limit plate 6 is flipped down and pressed against the side wall of the lock mouth under the action of the limit spring. The size of the safety plate 1 matches the size of the lock mouth. Since the safety plate 1 is mainly used to prevent people from accidentally falling, it can also play a good waterproof role on rainy days, so there is no need to add additional fixing function. The safety plate 1 is stuck on the side wall of the lock mouth under the action of the limit plate 6, and will not move without intentional application of additional external force, preventing the safety plate 1 from moving during operation. When it is not in use and needs to be temporarily disassembled, it can be easily flipped over and removed. It is easy to operate. When working, the construction plate 5 is flipped open for people to enter the pile hole and lift the bucket, as well as for ladders, lighting, exhaust equipment, etc. After the work is completed on the day, the construction plate 5 can be flipped over and closed to prevent people from accidentally falling.
[0030] When not in operation, four fences 2 surround the safety plate 1 for protection. During construction, the fence 2 on one side of the hoist is dismantled for operation. The warning light 3 can play a good warning role at night, and a warning sign is installed on the fence 2.
[0031] Furthermore, an extension plate 7 is extended and fixed on one end of the construction board 5 away from the hinge, and a limiting platform 8 corresponds to the matching side of the construction hole 4. When flipped closed, the extension plate 7 is buckled on the limiting platform 8 to prevent the construction board 5 from continuing to flip downward and to limit it.
[0032] Furthermore, for the construction workers in the pile hole 9, in order to prevent the collapse of the retaining wall or the bucket from causing injuries, a plurality of protective mesh panels 10 are installed correspondingly on the upper and lower sides of one side of the pile hole 9. The protective mesh panels 10 are provided with a plurality of mesh holes, and the protective mesh panels 10 are fixed on the side walls of the pile hole 9 of each section.
[0033] Furthermore, a through hole 11 is provided on the protective mesh 10. The diameter of the through hole 11 is larger than the diameter of the bucket. The through hole 11 is used to limit the position of the bucket to prevent the bucket from shaking due to constant position changes, which may cause the bucket itself or soil inside the bucket to fall. In order to further limit the lifting position of the bucket, a plurality of vertical steel bars 12 evenly distributed in a circle are tied around the through hole 11. The bottom end of the vertical steel bar 12 is tied to the bottom section of the protective mesh 10, and the middle is tied to the corresponding protective mesh 10. The upper end of the steel bar 12 passes through the top section of the protective mesh 10 and is placed at the pile mouth. The steel bar 12 passes through each section of the protective mesh 10 and is fixed to the protective mesh 10.
[0034] Furthermore, in order to further ensure the position of the bucket and prevent the soil in the bucket from falling to the outside, a plurality of retaining rings 13 are tied around the outer periphery of the steel bar 12 to limit the position of the bucket and prevent the soil or bucket from falling onto the protective mesh 10.
[0035] Furthermore, the through hole 11 is not placed at the center of the protection mesh plate 10, but is placed at the side of the protection mesh plate 10, leaving enough space for construction workers to stand.
[0036] Furthermore, in order to ensure that the bucket itself or the soil inside the bucket will not fall and hit the construction workers if they accidentally fall, a baffle 14 is rotatably connected to the through hole 11 of the first section. The baffle 14 is the same size as the through hole 11, and a blocking plate 16 is rotatably connected to the other side corresponding to the through hole 11 via a rotating shaft 15. A return spring 17 is sleeved on the rotating shaft 15 of the blocking plate 16. In the initial position, the return spring 17 makes the blocking plate 16 in a horizontal position. The baffle 14 is placed above the blocking plate 16 and cannot rotate downward. A pull rope 18 is fixed to the lower end of the blocking plate 16.
[0037] In the initial position, the baffle 14 closes the through hole 11, and the blocking plate 16 intercepts the baffle 14 so that the baffle 14 cannot move, which can prevent the bucket and soil from falling downward. When the bucket is transported downward normally, the construction worker hears the sound of the intercom or the empty bucket hitting the baffle 14, and then pulls the pull rope 18 by hand to pull down the baffle 16. At this time, the baffle 14 rotates under the action of gravity, so that the baffle 14 opens, and the bucket can pass normally. When the bucket moves upward, after the bucket passes through the baffle 14, the construction worker stands beside the through hole 11 and manually rotates the baffle 14 upward to the initial position, and releases the pull rope 18, so that the baffle 16 returns to its original position to block the baffle 14.
[0038] The bucket moves in the through hole 11, which effectively limits the position of the bucket. In case of an accident, whether the bucket or the soil block falls, it can only fall onto the baffle 14 under the limitation of the steel bars 12 and the retaining ring 13, so that the construction workers can work safely, instead of having to stand under the protective mesh 10 to avoid it during the lifting of the bucket as in the traditional way, and not knowing the falling position of the bucket and the soil block.
[0039] Furthermore, in order to prevent the impact force caused by the bucket falling as a whole from being greater than the reset spring 17 that forces the baffle 14 to open, a rotating shell 19 is installed coaxially on the outer side of the rotating shaft 15. The rotating shell 19 is fixedly installed on the protective mesh plate 10, and the rotating shaft 15 is rotatably installed on the rotating shell 19. A ratchet 20 is coaxially fixed on the rotating shaft 15, and the ratchet 20 is placed in the rotating shell 19. A pawl 21 is rotatably installed at the lower end of the rotating shell 19. The pawl 21 matches the ratchet 20, so that the rotating shaft 15 cannot rotate downward. A coil spring 23 is sleeved on the rotating shaft of the pawl 21, and a rope 22 passing through the rotating shell is fixed at the lower end of the pawl 21.
[0040] The pawl 21 matches and clamps the ratchet 20 so that it cannot rotate downward. When the baffle 14 needs to be opened, the pawl 21 is rotated with the rope 21 so that the pawl 21 falls off the ratchet 20, and then the pull rope 18 is pulled to rotate the blocking plate 16 downward. After that, the baffle 14 opens downward under the action of gravity, and the bucket passes normally. When it needs to be closed, the baffle 14 is first rotated upward by hand, and the pull rope 18 is released. The blocking plate 16 limits the baffle 14, and the ratchet 20 and the pawl 21 are aligned, and the pawl 21 does not need to be rotated.
[0041] The utility model installs a safety plate at the lock mouth to ensure the safety of the pile hole. The limiting plates around it are stuck on the side walls of the lock mouth and are not easy to move. The construction plate can be opened and closed, which can not only ensure normal construction but also ensure the safety of the pile hole after the construction is completed. At the same time, it plays a certain rainproof role. The fence and warning light can play a warning and safety protection role.
[0042] The protective mesh can prevent the hole wall from collapsing and soil from falling and hitting people. The bucket can be limited by the cooperation of holes and steel bars to prevent the bucket from shaking widely when it is lifted and lowered, and to prevent the bucket and soil from falling in any direction during the falling process.
[0043] The cooperation of the baffle and the blocking plate can block the bucket in the event of an accidental fall. The cooperation of the ratchet and the pawl ensures that the baffle will not be forced to open even if the bucket falls as a whole, further ensuring the safety of the construction workers. At the same time, the construction workers only need to pull the wire rope and the pull rope without adding additional operating intensity. The bucket does not need to always hide under the protective mesh when rising, which greatly increases the safety protection of the construction.
[0044] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the utility model. After reading the above content, various modifications and substitutions of the utility model will be obvious to those skilled in the art. Therefore, the protection scope of the utility model should be limited by the attached claims.
