[0002] In the bored pile, a steel casing is often buried to position the pile site to be drilled.

[0003] Because multiple places need to be drilled during on-site construction, multiple pile foundation casings are required. The multiple pile foundation casings are invariably placed randomly on the ground. Because the pile foundation casings are not reasonably stacked, a series of problems such as inconvenient transfer, occupation of more space, contact with the ground, easy damage, danger after rolling due to external force, and inability to concentrate on transfer are caused.

[0004] A pile foundation guide pipe storage rack is disclosed in Chinese patent No. CN201720874581.0, which comprises a bottom frame, a vertical rod, a lifting ring, a wheel, and a steel wire rope. The bottom frame is composed of two longitudinal baffles, two horizontal baffles, and reinforcing steel bars. The two longitudinal baffles and the two horizontal baffles are enclosed and welded into a square frame. The reinforcing steel bars are welded to the inner side of the lower part of the longitudinal baffle and the horizontal baffle. At least four vertical rods are arranged on the opposite sides of the two groups of the bottom frame. The lifting ring is arranged on the vertical rod. The steel wire rope passes through the lifting ring to fix at least one pile foundation guide pipe on the storage rack. The wheel is arranged on the lower end surface of the vertical rod.

[0039] Embodiment 1:

[0040] As shown in Figure 1 and Figure 2 , the present application provides a pile foundation casing protection device, which comprises:

[0041] The protection unit comprises a plurality of fixed bases 1 connected end to end to form a closed protection ring.

[0042] The connecting block is rotatably provided between adjacent fixed bases 1, and when the number of connecting blocks is greater than 1, the connecting blocks are arranged in sequence.

[0043] In this embodiment, the number of fixed bases 1 and connecting blocks can be selected by the workers according to the number and stacking form of the pile foundation casings, and the number of connecting blocks between adjacent two fixed bases can also be increased according to the actual situation.

[0044] The plurality of fixed bases 1 are connected together by the connecting blocks, and finally the fixed base 1 at the head end and the fixed base 1 at the tail end are connected together by the connecting blocks to form a closed and tensioned protection ring to protect the stacked pile foundation casings. The plurality of pile foundation casings are located inside the protection ring to avoid accidental sliding of the pile foundation casings from a high place, and the safety of construction is improved.

[0045] The specific working process is as follows: in this embodiment, nine protection units are provided to limit and protect seven pile foundation casings, and this is taken as an example.

[0046] Nine fixed bases 1 are connected together through connecting blocks, three pile foundation casings are placed on the three fixed bases 1 in the middle in turn, and then the pile foundation casings are stacked, and it can be known that, in order to ensure the stability of the stacking, the pile foundation casings are stacked from bottom to top, and the number of the pile foundation casings gradually decreases.

[0047] Since the connecting blocks are rotationally connected with the fixed bases 1, the fixed bases 1 can always adhere to the surface of the pile foundation casings.

[0048] Finally, the fixed base 1 at the front end and the fixed base 1 at the tail end are connected together through the connecting blocks to form a closed and tensioned protective ring to protect the stacked pile foundation casings, avoid the pile foundation casings at high positions from accidentally falling, and improve the safety of construction.

[0049] As shown in Figure 2 and Figure 3 Further shown, the fixed base 1 and the connecting block are connected in the following manner: the connecting block comprises a body 2, one end of the body 2 extends outward to form a first protrusion 3, and the other end is recessed inward in the middle to form a U-shaped groove 4.

[0050] One end of the fixed base 1 is provided with a first clamping groove 5 for cooperating with the first protrusion 3, and the other end is provided with a second clamping groove 6 for cooperating with the U-shaped groove 4.

[0051] In order to facilitate the removal of the pile foundation casings in clamping and fixing, both ends of the fixed base 1 are rotationally connected with different connecting blocks through first pin shafts 7, and here refer to Figure 2 In the embodiment, the first protrusion 3 cooperates with the first clamping groove 5, the U-shaped groove 4 cooperates with the second clamping groove 6, and both are provided through the first pin shaft 7 to realize the rotational connection of the connecting block and the fixed base 1.

[0052] In addition, when the pile foundation casing needs to be removed, the first pin shaft 7 is removed to disconnect the connecting block and the fixed base 1, thereby facilitating the removal of the pile foundation casing.

[0053] In order to further adjust the distance between the two adjacent fixed bases 1 to adhere and tension the pile foundation casings of different sizes, as shown in Figure 2 According to another embodiment of the present application, at least two connecting blocks are provided between the adjacent fixed bases 1, the first protrusion 3 on one of the connecting blocks is slidably connected with the U-shaped groove 4 on the other adjacent connecting block, and the two connecting blocks are rotationally connected through a second pin shaft 8.

[0054] In the embodiment, the two connecting blocks are also connected in a head-to-tail manner, and the spacing between the two adjacent fixed bases 1 is changed by adding the connecting blocks, so as to better adapt to pile foundation casings of different sizes. In the embodiment, the two adjacent fixed bases 1 are connected by two connecting blocks. It should be understood that the number of connecting blocks of the present application is not limited to two, and the number of connecting blocks can be increased according to the specific circumstances.

[0055] In addition, the two connecting blocks are connected by rotating the second pin shaft 8, and when the second pin shaft 8 is removed, the two connecting blocks can also be disconnected, which facilitates the subsequent removal process of the pile foundation casing.

[0056] As shown in Figure 3 and Figure 4 Further, the second pin shaft 8 penetrates the first protrusion 3 on one of the connecting blocks and is connected in rotation with the connecting block, and the U-shaped slot 4 on the other connecting block is provided with a sliding hole 9 penetrating and extending in the radial direction of the casing. The second pin shaft 8 is rotatably and slidably connected in the sliding hole 9.

[0057] Through the above arrangement, the two connecting blocks can slide relative to each other while not affecting the rotation of each other, ensuring the softness of the original protective ring. In addition, the two connecting blocks can also slide relative to each other, further adjusting the spacing between the two connecting blocks to adjust the spacing between the adjacent fixed bases 1, as Figure 3 The sliding hole 9 in the embodiment is provided with an adjusting assembly for adjusting the spacing between the two connecting blocks.

[0058] After the two connecting blocks are arranged between the adjacent fixed bases 1, the two connecting blocks can slide relative to each other. When the two adjacent fixed bases 1 do not need the two connecting blocks to increase the spacing and one connecting block is too short, the embodiment can be provided with an adjusting assembly to fine-tune the spacing between the two adjacent connecting blocks to ensure that the fixed base 1 can effectively abut against the pile foundation casing. The adjusting assembly comprises a limiting shaft 10 threadedly connected with the body 2 and extending into the sliding hole 9, and one end of the limiting shaft 10 is rotatably provided with a sliding plate abutting against the second pin shaft 8.

[0059] Herein Figure 3 When there is no adjusting assembly, the second pin shaft 8 can be at the leftmost side of the sliding hole 9, so that the spacing between the two adjacent fixed bases 1 is the longest. However, only when the second pin shaft 8 is at the leftmost side, the second pin shaft 8 can no longer slide. Therefore, the embodiment is provided with an adjusting assembly in the sliding hole 9 to drive the second pin shaft 8 to move to the right until the two adjacent fixed bases 1 are in a tension state.

[0060] The specific working process of the adjusting assembly is as follows: the limiting shaft 10 extends into the sliding hole 9 and is threadedly connected with the body 2. By rotating the limiting shaft 10, the limiting shaft 10 can enter the sliding hole 9 while rotating, thereby pushing the sliding plate to move, and finally pushing the second pin shaft 8 to move to the right until the two adjacent fixed bases 1 are in a tension state.

[0061] The end of the sliding plate used for abutting against the second pin shaft 8 is also connected with a rubber pad. Through the setting of the rubber pad, on the one hand, the abrasion of the second pin shaft 8 caused by the direct contact between the sliding plate and the second pin shaft 8 is avoided, and on the other hand, the friction force between the sliding plate and the second pin shaft 8 is increased, so that the second pin shaft 8 is better abutted and pushed to slide.

[0062] Embodiment 2:

[0063] In this embodiment, the fixed base 1 comprises a supporting block 18 and a positioning block 19 connected to one side of the supporting block 18, and the positioning block 19 is used for contacting the surface of the pile foundation casing.

[0064] Specifically, the positioning block 19 has two arrangement forms.

[0065] Firstly, one side of the positioning block 19 abutting against the pile foundation casing is recessed inward to form an arc-shaped groove. The setting of the arc-shaped groove increases the contact area with the pile foundation casing, thereby ensuring the stability of the fixation of the pile foundation casing.

[0066] Secondly, the positioning block 19 comprises two arc-shaped blocks 11 respectively abutting against two sides of the pile foundation casing, and the supporting block 18 is internally arranged with a clamping assembly driving the two arc-shaped blocks 11 to move towards or away from each other, thereby further strengthening the clamping action of the positioning block 19 and the pile foundation casing. The clamping assembly comprises:

[0067] a driving member, which is arranged in the supporting block 18 and connected with the two arc-shaped blocks 11;

[0068] a starting block 12, which is connected with the driving member and located at the top of the driving member and arranged between the two arc-shaped blocks 11.

[0069] The specific working process is as follows: the starting block 12 is pressed to drive the driving member to work, the driving member drives the two arc-shaped blocks 11 to move towards each other, and the two arc-shaped blocks 11 are respectively clamped on the two sides of the pile foundation casing, thereby further ensuring that the pile foundation casing is not easy to fall off and improving the safety of the device.

[0070] Further, the driving member comprises:

[0071] a pressing block 13, which is vertically and slidingly arranged in the supporting block 1, the top of the pressing block 13 is fixedly connected with the starting block 12, and two transverse sliding grooves 14 are symmetrically arranged on the pressing block 13, and a spring 15 is connected between the pressing block 13 and the bottom of the supporting block;

[0072] a sliding block 16, which is provided with two and is respectively and slidingly connected in the two transverse sliding grooves 14, and the two sliding blocks 16 are respectively and rotationally connected with the two arc-shaped blocks 11;

[0073] Rotating shafts 17 are arranged above the pressing blocks 13, and two rotating shafts 17 are arranged transversely and fixedly, and each rotating shaft 17 is connected with an arc-shaped block 11 in a rotating mode.

[0074] The specific working process of the driving member is as follows: the starting block 12 is pressed, and the pressing force of the starting block 12 can be the weight of the pile casing or the force generated by the side of the pile casing; the pressing block 13 is driven to move downwards, the two sliding blocks 16 move away from each other in the corresponding transverse sliding grooves 14, and finally the two arc-shaped blocks 11 are driven to move towards each other to clamp and lock the pile casing.

[0075] When the starting block 12 is not pressed, the spring 15 rebounds to drive the pressing block 13 to move upwards, the two sliding blocks 16 move towards each other in the corresponding transverse sliding grooves 14, and finally the two arc-shaped blocks 11 are driven to move towards each other to automatically release the locking of the pile casing, without affecting the removal of the pile casing.

[0076] The specific working process of the present application is as follows:

[0077] The number of fixed bases 1 and connecting blocks is selected according to the number and stacking form of the pile casings.

[0078] The two connecting blocks are connected by the two connecting blocks, and the two connecting blocks are connected by the second pin shaft 8.

[0079] Then, the adjusting assembly is used as needed, the limiting shaft 10 is rotated, the limiting shaft 10 enters the sliding hole 9 while rotating to drive the sliding plate to move, and finally the second pin shaft 8 is driven to move until the two adjacent fixed bases 1 are in a tension state.

[0080] The pile casings are placed above the plurality of fixed bases 1 located in the middle position in sequence, and then the pile casings are stacked, and since the connecting blocks are connected with the fixed bases 1 in a rotating mode and the distance between the two adjacent fixed bases 1 is accurately adjusted by the adjusting assembly, the fixed bases 1 can always fit the surface of the pile casings.

[0081] Finally, the fixed base 1 at the first end and the fixed base 1 at the end are connected together by the connecting block to form a closed and tensioned protective ring to protect the stacked pile casings, avoid the pile casings from sliding down accidentally, and improve the safety of construction.

[0082] It should be noted that when the positioning block 19 is recessed to form an arc-shaped groove, the arc-shaped groove is fitted with the surface of the pile casing to better fix the pile casing.

[0083] When the positioning blocks 19 are two arc-shaped blocks 11, the supporting blocks 18 are provided with clamping assemblies, and the operation process is as follows: the starting blocks 12 are pressed, the pressing force of the starting blocks 12 can be the weight of the pile foundation sleeve or the force generated by the side of the pile foundation sleeve; the pressing blocks 13 are driven to move downward, the two sliding blocks 16 are driven to move away from each other in the corresponding horizontal sliding grooves 14, and finally the two arc-shaped blocks 11 are driven to move toward each other to clamp and lock the pile foundation sleeve.

[0084] When the starting blocks 12 are not pressed, the springs 15 rebound to drive the pressing blocks 13 to move upward, the two sliding blocks 16 are driven to move toward each other in the corresponding horizontal sliding grooves 14, and finally the two arc-shaped blocks 11 are driven to move away from each other to automatically release the locking of the pile foundation sleeve, and the pile foundation sleeve can be taken out without influence.

[0085] When the pile foundation sleeve needs to be taken out, the second pin shaft 8 is removed to disconnect the connection of the two connection blocks at the top, and when the pile foundation sleeve needs to be continuously protected after being taken out, one or more fixed bases 1 can be removed to form a tensioned protection ring again. The process is convenient, and the fixed base 1 and the connection block can be reused.

[0086] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and they should be covered in the scope of the claims of the present application.
