Description

Technical Field

[0001] The utility model belongs to the technical field of gas pipeline connectors, and particularly relates to an anti - detachment gas pipeline connector applicable to a pneumatic coal bunker cleaning robot. Background Art

[0002] To solve the problem of cleaning the underground coal bunker, a pneumatic coal bunker cleaning robot in the prior art (description attached Figure 6 ) adopts a fully pneumatic control system. However, many existing gas pipeline connectors use a relatively simple buckle design and lack necessary safety protection measures. As a result, in an environment of high pressure or severe vibration, the connectors are prone to loosening or falling off. If directly using off - the - shelf gas pipeline connectors, it may cause gas leakage or equipment damage. Conventional countermeasures usually include adding locking devices or improving the wear surface treatment of the connectors to improve the anti - detachment ability of the connectors. However, the implementation of these methods is often limited by economic costs and product complexity, increasing production costs or complicating installation and maintenance. The added locking devices may have difficulties in operability, resulting in longer time consumption for users when quickly connecting or disconnecting, reducing work efficiency. Therefore, we hope to design a gas pipeline connector with a new structure to solve this problem. Summary of the Utility Model

A connecting pipe is integrally provided on the upper side of the connecting head. A concave groove is formed by downward depression at the upper end of the connecting pipe. An extension pipe is provided in the middle of the concave groove.

[0010] As a preferred embodiment, the diameter of the extension pipe gradually increases from top to bottom. The air hole penetrates through the extension pipe upward, and the axis of the air hole is collinear with the axis of the extension pipe and the axis of the second threaded pipe.

[0024] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: an anti - detachment air - path joint for a pneumatic cleaning robot applicable to a coal bunker, including: a joint assembly 100 and a sleeve tube 200. A joint assembly 100 for fixing the end head 110 of the air pipe is installed at the left end and the right end of the sleeve tube 200 respectively. The joint assembly 100 includes an end head 110 and a connector 120;

[0025] The end head 110 is threadedly connected to the connector 120 at the end close to the sleeve tube 200, and a first clamping hole 210 is provided at the lower end of the sleeve tube 200;

[0026] A threaded hole 220 is provided in the middle of the sleeve tube 200, and a second clamping hole 230 is provided inside the upper end of the sleeve tube 200.

[0027] Please refer to Figures 1 to 3 and Figure 5The upper end of the end cap 110 is recessed downward to form a bell mouth 111. The inner diameter of the bell mouth 111 gradually decreases from top to bottom. The bottom of the bell mouth 111 penetrates downward to form a catheter hole 112. The inner diameter of the upper end of the catheter hole 112 is the same as the inner diameter of the lower end of the bell mouth 111. The setting of the bell mouth 111 is used to make way for the trachea and reduce the wear at the connection between the trachea and the end cap 110.

[0028] A threaded tube 113 is integrally provided at the lower end of the end cap 110, and a catheter hole 112 penetrates downwardly through the threaded tube 113. The diameter of the threaded tube 113 is smaller than the diameter of the upper part of the end cap 110. The inner wall of the catheter hole 112 located inside the threaded tube 113 is radially outwardly provided with a plurality of equally spaced annular grooves.

[0029] A threaded tube 121 is integrally provided at the lower end of the connector 120 , and an air hole 122 is provided inside the threaded tube 121 . A connecting tube 123 is integrally provided at the upper side of the connector 120 , and the upper end of the connecting tube 123 is recessed downward to form a slot 124 , and an extension tube 125 is provided in the middle of the slot 124 .

[0030] The diameter of the extension tube 125 gradually increases from top to bottom, the air hole 122 penetrates the extension tube 125 upward, and the axis of the air hole 122 is colinear with the axis of the extension tube 125 and the axis of the threaded tube 121. The air hole 122 is connected to the inside of the air pipe installed inside the joint assembly 100 to facilitate air conduction.

[0031] As the first embodiment of the utility model, in actual use, the end of the trachea is first inserted into the end of the end 110 through the bell mouth 111 and the catheter hole 112, and the lower end of the catheter is flush with the lower end of the threaded tube 113, and then the connecting tube 123 of the connector 120 is threadedly connected with the threaded tube 113. As the connecting tube 123 and the threaded tube 113 are screwed in, the extension tube 125 located inside the connecting tube 123 is gradually inserted into the inner wall of the trachea located inside the threaded tube 113. Due to the extension tube 125 The diameter increases gradually from top to bottom, the air hole 122 penetrates the extension tube 125 upward, and the inner wall of the catheter hole 112 located inside the threaded tube 113 is radially outwardly provided with a plurality of equally spaced annular grooves. The extension tube 125 enters the interior of the trachea and continuously squeezes it toward the annular grooves on the inner wall of the catheter hole 112, thereby firmly fixing the lower end of the trachea inside the threaded tube 113. At this point, the joint assembly 100 is tightly connected to the end of the trachea on one side to be connected, greatly reducing the probability of detachment caused by factors such as high air pressure.

[0032] See also Figures 1 to 4 as well as Figure 6, the diameter of the connecting pipe 123 matches the inner diameter of the first clamping hole 210. The inner diameter of the first clamping hole 210 is the same as the inner diameter of the second clamping hole 230.

[0033] As the second embodiment of the present utility model, based on the above first embodiment, in actual use, the ends of the air pipes to be connected on both sides are fixed by two joint assemblies 100 (the air pipes to be connected on both sides are respectively connected to the external air supply equipment and the coal bunker pneumatic cleaning robot in the prior art, see the attached Figure 6 in the specification, that is, the present utility model can be matched with the coal bunker pneumatic cleaning robot in the prior art, and thus can achieve a complementary effect, ensuring the stable air supply during the operation of the coal bunker pneumatic cleaning robot, and preventing the situation of the disconnection of the air pipe connection resulting in downtime). Subsequently, the second threaded pipes 121 of the two joint assemblies 100 are inserted into the threaded hole 220 through the first clamping hole 210 or the second clamping hole 230, and then the sleeve pipe 200 is rotated. The second threaded pipe 121 is threadedly connected to the sleeve pipe 200 through the threaded hole 220 (in actual use, the outer thread rotation directions on the outer sides of the second threaded pipes 121 on the two joint assemblies 100 are opposite, so that only by rotating the sleeve pipe 200 can the threaded connection of the two joint assemblies 100 be completed), thereby firmly fixing the two joint assemblies 100. And ventilation is achieved through the air holes 122 on the two joint assemblies 100. By firmly locking the ends of the two air pipes, and firmly fixing the ends of the two connected air pipes through the sleeve pipe 200 and the two joint assemblies 100, the situation of disconnection during its use is avoided, greatly improving the use stability of the entire joint structure.
