[0002] In the pile driving operation of building construction, in order to ensure the stability of the building structure, the depth of the pile hole is very deep. At this time, in order to prevent people or objects from falling into the pile hole, it is necessary to use a pile hole protection device. Therefore, the pile hole protection device is the most common device in the pile driving operation of building construction.

[0003] In the prior art, steel pipes, water horses and warning signs are mostly used for pile hole protection. By placing them near the pile hole, the pile hole can be well protected. For some large-diameter piles, a protective frame needs to be erected with long steel pipes.

[0004] However, the protective frame is not only heavy but also has poor protection effect. At the same time, the construction efficiency is low, it is not convenient for turnover use, and it is not convenient for folding. Storage, storage and transportation are extremely inconvenient. There are many related accessories and it is easy to lose them. Content of the Utility Model

[0005] The purpose of the utility model is to provide a foldable pile hole protection device to solve the problem that the currently used pile hole protection device is not convenient for folding, storing and transporting as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A foldable pile hole protection device, including: a base and a chute. A vertical rod is installed on the top of the base, and the chute is opened around the vertical rod.

[0007] Preferably, a slider is slidably connected inside the chute. One side of the slider is connected with a rotating protection rod through a rotating shaft, and a connecting shaft is installed in the middle of the rotating protection rod.

[0008] Preferably, one side of the connecting shaft is penetrated and connected with a screw rod, and one side of the screw rod is connected with a movable block penetrating the connecting shaft through a bearing.

[0009] Preferably, a clamping block is installed on one side of the movable block, and a convex block is installed on the side of the clamping block away from the movable block.

[0010] Preferably, a mounting block is sleeved on the top of the vertical rod, and an inserting block is installed at the bottom of the mounting block.

[0011] Preferably, a fixing block is sleeved on the outside of the inserting block, and a rotating block is connected through a rotating shaft in a groove on one side of the inserting block.

[0012] Preferably, a telescopic block is provided on one side of the rotating block, and a movable spring is installed between the telescopic block and the groove of the inserting block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] When the foldable pile hole protection device proposed by the present utility model is in use, the screw can be rotated according to needs, so that the screw drives the clamping block to separate from the convex block through the movable block. At this time, without the docking of the clamping block and the convex block, the connecting shaft can drive the rotating protection rod to rotate, and the sliding block on the other side of the rotating protection rod can slide along the sliding groove of the vertical rod. Through the sliding of the two groups of sliding blocks away from each other, the two groups of vertical rods can move closer to each other, so that the entire protection device can be folded and stored, reducing the placement space. After the storage is completed, the screw is rotated in the reverse direction, so that the clamping block and the convex block limit and fix the connecting shaft, thereby ensuring that the entire protection rotating shaft will not become loose.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a foldable pile hole protection device, including: a base 1 and a chute 3. A vertical rod 2 is installed on the top of the base 1, and the chute 3 is opened around the vertical rod 2.

[0026] A slider 4 is slidably connected inside the chute 3. One side of the slider 4 is connected by a rotating shaft to a rotating protection rod 5. A connecting shaft 6 is installed in the middle of the rotating protection rod 5. One side of the connecting shaft 6 is penetrated and connected with a screw rod 7. One side of the screw rod 7 is connected by a bearing to a movable block 8 that penetrates the connecting shaft 6. A clamping block 9 is installed on one side of the movable block 8. A convex block 10 is installed on the side of the clamping block 9 away from the movable block 8. The convex block 10 is installed on one side of one group of rotating protection rods 5. Two groups of rotating protection rods 5 are cross-installed with respect to the center line of the connecting shaft 6. The connecting shaft 6 is connected to one group of rotating protection rods 5 and penetrates and is inserted into the other group of rotating protection rods 5.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to realize the folding function of the entire pile hole protection device, the screw rod 7 can be rotated. Since the screw rod 7 is threadedly connected to the connecting shaft 6, and one side of the screw rod 7 is connected to the movable block 8 through a bearing, rotating the screw rod 7 at this time will drive the movable block 8 to move to one side, causing the latch 9 on one side of the movable block 8 to separate from the convex block 10. Without the docking of the latch 9 and the convex block 10, and the connecting shaft 6 is connected to one set of rotating protection rods 5. At this time, the rotating protection rod 5 can be pushed to rotate the connecting shaft 6. When one set of rotating protection rods 5 rotates, the slider 4 will slide along the chute 3 of the vertical rod 2 through the rotating shafts on both sides. Since the inclination angle of the rotating protection rod 5 changes, the two vertical rods 2 can move closer to each other at this time. The middle of the other set of rotating protection rods 5 is connected to the connecting shaft 6 through a bearing. As the vertical rods 2 move closer to each other, the other set of rotating protection rods 5 will rotate under the cooperation of the slider 4 and the rotating shaft. Repeating the above steps, the other vertical rods 2 will also move closer to each other, so as to fold and store the entire pile hole protection device, which is convenient for carrying and transporting the pile hole protection device. Then rotate the screw rod 7 in the reverse direction, so that the screw rod 7 drives the latch 9 on one side to move through the movable block 8 and dock the latch 9 with the convex block 10. At this time, the connecting shaft 6 cannot rotate under the action of the latch 9 and the convex block 10, so that the rotating protection rod 5 can be fixed, making the entire pile hole protection device not prone to looseness and ensuring the stability of the entire pile hole protection device.

[0029] An installation block 11 is sleeved on the top of the vertical rod 2. An insertion block 12 is installed at the bottom of the installation block 11. A fixing block 13 is sleeved on the outside of the insertion block 12. A rotating block 14 is connected to the groove on one side of the insertion block 12 through a rotating shaft. A telescopic block 15 is arranged on one side of the rotating block 14. A movable spring 16 is installed between the telescopic block 15 and the groove of the insertion block 12. The rotating block 14 and the groove of the insertion block 12 form a rotating structure through the rotating shaft.

[0030] Embodiment Three

[0031] On the basis of the second embodiment, in order to achieve the function of quickly assembling the pile hole protection device, the rotating block 14 can be squeezed, and the rotating block 14 is squeezed into the groove of the inserting block 12. When the rotating block 14 rotates, it will squeeze the telescopic block 15 in the groove of the inserting block 12, causing the telescopic block 15 to shrink into the groove of the inserting block 12 and squeeze the movable spring 16 in the groove. When the rotating block 14 completely rotates into the groove of the inserting block 12, it no longer limits the inserting block 12. At this time, the mounting block 11 can be pulled upward, and the mounting block 11 will drive the inserting block 12 to move out of the through hole of the fixed block 13, so that the mounting block 11 can be detached from the top of the vertical rod 2, and the chute 3 penetrating the side of the vertical rod 2 is exposed. At this time, according to the installation requirements, the slider 4 can be slidably installed on one side of the vertical rod 2 through the chute 3, and the position of the slider 4 can be adjusted. Then, the mounting block 11 is sleeved on the top of the vertical rod 2, and the inserting block 12 is inserted into the through hole of the fixed block 13. During the insertion process, the inner wall of the fixed block 13 will squeeze the rotating block 14, causing the rotating block 14 to shrink into the groove of the inserting block 12 again. When the rotating block 14 completely moves to the bottom of the fixed block 13, the rotating block 14 is no longer squeezed by the inner wall of the fixed block 13. The rotating block 14 will be reset through the telescopic block 15 and the movable spring 16, causing the telescopic block 15 to push the rotating block 14 to rotate in the reverse direction, so that the inserting block 12 can be limited in the fixed block 13, and the mounting block 11 cannot fall off the vertical rod 2. The mounting block 11 can block the chute 3 on the side of the vertical rod 2, preventing the slider 4 from sliding out of the chute 3 during use, thus facilitating the user to quickly assemble the pile hole protection device.

[0032] During actual use, for this folding pile hole protection device, when in use, the entire vertical rod 2 can be placed in a stable position through the base 1. Then, the vertical rod 2 can be unfolded by rotating the protective rod 5 according to the position of the pile hole, and the protection device can be increased or decreased according to requirements. Finally, the protection device is wrapped around the position of the pile hole to form a square and its head and tail are connected. At this time, the vertical rod 2 and the rotating protective rod 5 can play a role in protecting the pile hole.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
