Description

Technical Field

[0001] This utility model relates to the field of construction auxiliary tools technology, and in particular to a one-way valve striking pin device. Background Technology

[0002] In the freezing project of the municipal subway connecting passage, the freezing holes are arranged at three angles: upward, horizontal, and downward. During the drilling process, the one-way valve plays a crucial role. The functions of the one-way valve are: ① to improve the soil density in front of the drill bit and accelerate drilling speed; ② to reduce the drill bit temperature and extend its service life; ③ to control the slurry flow in one direction; and ④ to prevent backflow of water and sand into the freezing holes. To prevent backflow of water and sand into the freezing holes during the installation of the freezing pipes, it is essential to ensure the smoothness of the one-way valve track and the reliability of the spring device. In areas with great burial depth, high ground pressure, confined aquifers, and water-rich sand layers, the one-way valve spring device has long been prone to problems such as incomplete closure and foreign object jamming, causing backflow of water and sand into the freezing holes and rendering the one-way valve ineffective. Therefore, a solution is urgently needed.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Example

[0023] See Figure 1-5 As shown: This utility model provides a one-way valve striker device, including: an impact hammer 10, a connecting part, and a flushing part. One end of the impact hammer 10 is used to strike the one-way valve that is not tightly closed in the freezing hole, and the other end of the impact hammer 10 is connected to one end of the connecting part. The other end of the connecting part is connected to a drive part that drives the impact hammer 10 to strike the one-way valve; the flushing part is disposed on the impact hammer 10 and the connecting part, one end of the flushing part is connected to a water pipe, and the other end is used to flush away foreign objects that cause the one-way valve to not close tightly.

[0024] In practical use, the length of the connecting part can be set according to the distance from the one-way valve to the outlet of the freezing hole. The connecting part is driven by the drive unit, which causes the impact hammer 10 to impact the one-way valve that is not closing tightly. During the impact, the impact force, i.e., the squeezing force, loosens the foreign object at the spring device of the one-way valve. Then, the high-pressure water flow provided by the flushing unit carries the foreign object out of the spring device, restoring the spring device of the one-way valve and ensuring that the one-way valve works normally, thereby solving the problem. The entire device has a simple structure, is easy to assemble and use, and can quickly solve the problem of one-way valve not closing tightly, improving construction efficiency.

[0025] In specific implementation, the impact hammer 10 is configured to consist of a hammer head 11, a connecting seat 12, and a connecting post 14. The hammer head 11 is configured as a cylinder with a ball end, so that it will not damage the one-way valve when impacted or squeezed. One end of the hammer head 11 is connected to one end of the connecting seat 12; the other end of the connecting seat 12 is connected to one end of the connecting post 14; and the other end of the connecting post 14 is threadedly connected to the connecting part.

[0026] An external thread 141 is provided on the outer wall of the connecting column 14; the connecting part includes a first connecting rod 20, a second connecting rod 30 and an end connecting rod 40.

[0027] Both ends of the first connecting rod 20 are provided with embedded internal threaded openings 21; one end of the second connecting rod 30 is provided with an externally protruding external threaded opening 31, and the other end is provided with an embedded internal threaded interface 32; one end of the end connecting rod 40 is provided with an externally protruding external threaded interface 41, and the other end is provided with a sealing cap 42.

[0028] During specific assembly, the external thread 141 on the end connecting rod 40 forms a threaded connection with the internal thread 21 at one end of the first connecting rod 20, and the external thread 31 on the second connecting rod 30 forms a threaded connection with the internal thread 21 at the other end of the first connecting rod 20; the external thread interface 41 on the end connecting rod 40 forms a threaded connection with the internal thread interface 32 on the second connecting rod 30, so that the connecting post 14, the first connecting rod 20, the second connecting rod 30 and the end connecting rod 40 form a threaded connection along the length direction.

[0029] In addition, the first connecting rod 20, the second connecting rod 30 and the end connecting rod 40 are all made of steel. The drive unit can be manually pushed or driven by a motor. However, during construction, it is generally done by striking one end of the connecting unit with a small hammer, which drives the impact hammer 10 at the other end of the connecting unit to impact or squeeze the one-way valve.

[0030] In practical use, there are at least two second connecting rods 30, so that the operator can adjust the number of second connecting rods 30 according to the distance from the one-way valve to the freezing hole outlet end to adjust the length of the entire connection part, ensuring that the impact hammer 10 can abut against one side of the one-way valve.

[0031] In addition, to improve the ease of use of the flushing unit and reduce the complexity of the overall device structure in practical applications, the connecting column 14, the first connecting rod 20, the second connecting rod 30, and the end connecting rod 40 are all hollow columns, and the connected connecting column 14, the first connecting rod 20, the second connecting rod 30, and the end connecting rod 40 are interconnected, forming a pipe. The flushing unit includes a flushing hole 13 and a flushing water pipe connector 43. The flushing hole 13 is located on the connecting seat 12 and communicates with the internal cavity of the connecting column 14; the flushing water pipe connector 43 is located on the end connecting rod 40, with one end of the flushing water pipe connector 43 communicating with the water pipe and the other end communicating with the internal cavity of the end connecting rod 40. When in use, simply inject high-pressure water into the flushing water pipe joint 43 through the water pipe to form a flushing water column at the flushing hole 13, thereby flushing the foreign objects at the one-way valve at the same time when the impact hammer 10 squeezes the one-way valve, which is simple and convenient.

[0032] To improve the flushing effect, the flushing holes 13 are set to have at least three holes, which are evenly distributed around the circumference of the hammer head 11. This allows for rapid flushing of the one-way valve's circumference during flushing, thereby improving the efficiency of foreign matter removal.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
