Description

Technical Field

[0001] This utility model relates to an improvement invention in the field of engineering machinery, and in particular to an improvement invention of a cement pile cap that allows for quick replacement of pile type. Background Technology

[0002] When constructing cement piles, pile pads need to be placed on top of the piles. Common types include paper pads and wooden pads. Existing pile caps include upper pile caps, replacement pile caps, and lower pile caps. The inner diameter of the lower pile cap is smaller than that of the upper pile cap, which helps to prevent the replacement pile from falling off. However, during the construction of cement piles, the top of the cement pile and the attached pile pad enter the upper pile cap through the lower pile cap. During the hammering process, the pile pad will expand, that is, the pile pad is flattened and its outer diameter becomes larger. Due to the limitation of the lower pile cap, it remains inside the upper pile cap and is difficult to remove.

[0003] Therefore, a sleeve is usually installed inside the pile cap to prevent the pile pad from expanding. However, the top of the pile pad is confined inside the upper pile cap. In cases where the pile type needs to be changed frequently, the upper and lower pile caps need to be disassembled and the sleeve removed, which is very troublesome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cement pile cap that can be quickly replaced.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A cement pile cap with quick-change pile type includes an upper pile cap, a replacement pile cap, and a lower pile cap. The replacement pile cap is movable up and down and matched within the upper pile cap. The top of the upper pile cap is provided with a hammering port. The lower pile cap forms a limit for the replacement pile cap to dislodge. The inner diameter of the lower pile cap is smaller than that of the upper pile cap. The feature is that the pile cap also has a sleeve adapted to the cement pile. The sleeve has a cylindrical cavity inside and a cover plate at the top. The sleeve is inserted from the lower end of the lower pile cap. The sleeve can move up and down, and the top of the sleeve can extend into the upper pile cap. The outer circle of the sleeve supports and cooperates with the inner circle of the lower pile cap. The lower end of the sleeve extends out of the lower pile cap. A first lifting lug is provided on the outer circle of the lower end of the sleeve, and a second lifting lug is provided on the outer circle of the corresponding lower pile cap. The first and second lifting lugs are connected by a flexible connection, and space is reserved for the sleeve to move up and down.

[0006] The flexible connection is a steel wire rope or chain.

[0007] The upper end of the substitute is fitted with a hammer pad.

[0008] The beneficial effects of this utility model are that the improved cement pile cap with quick pile type replacement is designed with a sleeve adapted to the cement pile. The sleeve has a straight cylindrical cavity and a cover plate on the top of the sleeve, which effectively prevents the pile pad from expanding and allows for easy removal of the used pile pad. At the same time, the sleeve is inserted into the lower pile cap from the bottom. The first lifting lug of the sleeve is connected to the second lifting lug of the lower pile cap by a steel wire rope or chain to prevent the sleeve from coming off. When it is necessary to change the pile type, the sleeve can be separated by disassembling the steel wire rope or chain, achieving quick separation. Attached Figure Description

[0009] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0012] Figure 3 This utility model Figure 2 AA sectional view. Detailed Implementation

[0013] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-3 This quick-change cement pile cap includes an upper pile cap 1, a replacement 2, and a lower pile cap 3. The upper pile cap 1 and the lower pile cap 3 are connected by a flange face. The replacement 2 can be moved up and down to match the upper pile cap 1. The top of the upper pile cap 1 is provided with a hammering hole 4. The lower pile cap 3 forms a limit for the replacement 2 to disengage. The inner diameter of the lower pile cap 3 is smaller than the inner diameter of the upper pile cap 1. The pile cap also provides a sleeve 5 adapted to the cement pile. The sleeve 5 has a straight cylindrical cavity. The top of the sleeve 5 is provided with a cover plate. The sleeve 5 is inserted from the lower end of the lower pile cap 3, and can move up and down. The top of the sleeve 5 can extend into the upper pile cap 1. The outer circle of the sleeve 5 and the inner circle of the lower pile cap 3 provide support and cooperation. The lower end of the sleeve 5 extends out of the lower pile cap 3. The lower outer circle of the sleeve 5 is provided with a first lifting lug 6, and the corresponding outer circle of the lower pile cap 3 is provided with a second lifting lug 7. The first lifting lug 6 and the second lifting lug 7 are connected by a flexible connection, and space is reserved for the upper and lower movement of the sleeve 5. This can restrict the sleeve 5 from detaching from the pile cap, but does not hinder the upper and lower movement of the sleeve 5 into the upper pile cap 1.

[0014] The working principle of this utility model is as follows: the sleeve 5 is inserted into the lower end of the lower pile cap 3. The sleeve 5 can move up and down, and the top of the sleeve 5 can extend into the upper pile cap 1. The first lifting lug 6 of the sleeve 5 and the second lifting lug 7 of the lower pile cap 3 are connected by a flexible connection to limit the sleeve 5 and prevent it from falling out. After the pile pad is placed and constructed, the straight cylindrical cavity of the sleeve 5 prevents the pile pad from expanding and makes it easy to remove the used pile pad. When it is necessary to change the pile type, the sleeve 5 can be separated by disassembling the flexible connection, achieving quick separation.

[0015] As a further improved implementation, the flexible connection is a steel wire rope or chain, which has good connection strength and is stable and reliable.

[0016] As a further improved specific implementation, the upper end of the substitute hammer 2 is embedded with a hammer pad 8, which mainly plays the role of uniformly transmitting stress during the hammering of the precast pile.

[0017] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
