Full-circle needle beam trolley feeding device

Abstract

This invention discloses a feeding device for a full-circular needle beam trolley, comprising: a fixing component; a base and a connecting pipe assembly disposed on the base; a locking component; a locking assembly comprising a locking component disposed in the connecting pipe assembly, a sealing component disposed in the connecting pipe assembly, and a guiding component disposed on the outside of the connecting pipe assembly; wherein, the connecting pipe assembly is connected by the locking component. When it is necessary to feed material into the grouting pipe, the diverter pipe is inserted into the connecting pipe, and the connecting pipe is rotated so that the long block corresponds to the through groove. The end of the diverter pipe contacts the inclined surface of the locking block, pushing the locking block to move. When the locking groove moves to correspond with the locking block, the return spring pushes the locking block into the locking groove. The return spring continues to push the protrusion of the locking block into the locking groove, causing the diverter pipe to slide continuously, driving the second fixing ring to squeeze the sealing ring. This allows for quick installation by inserting the diverter pipe into the connecting pipe. By squeezing the sealing ring, the connection between the diverter pipe and the connecting pipe is sealed, preventing material leakage.

[0045] Example 1

[0046] Reference Figure 1-5 A schematic diagram of the overall structure of a full-circular needle beam trolley feeding device is provided, including a full-circular needle beam trolley feeding device, comprising,

[0047] The fixing component 100 includes a base 101 and a connecting pipe assembly 102 disposed on the base 101.

[0048] Locking component 200 includes an engaging component 201 disposed in the connecting pipe assembly 102, a sealing component 202 disposed in the connecting pipe assembly 102, and a guide component 203 disposed on the outside of the connecting pipe assembly 102; wherein, the connecting pipe assembly 102 is connected by the engaging component 201, the base 101 is U-shaped, and the connecting pipe assemblies 102 are all fixedly disposed in the base 101. This device is disposed in such a way as... Figure 1 Position M in the middle.

[0049] Specifically, the connecting pipe assembly 102 includes a fixed pipe 102a disposed on the base 101, a connector 102b disposed at the end of the fixed pipe 102a, and a diversion pipe 102c disposed on the base 101; wherein, the fixed pipe 102a is connected to the diversion pipe 102c through the connector 102b, the fixed pipe 102a is fixedly disposed on one side of the base 101, and multiple diversion pipes 102c are fixedly disposed on the other side, and the diversion pipes 102c can be configured as follows: Figure 1 The number of grouting pipes K shown is correspondingly set. A connector 102b is fixedly provided at the end of the fixed pipe 102a. A locking component 201 is provided in the connector 102b. The diversion pipe 102c is inserted into the connector 102b. The connector 102b is fixed to the diversion pipe 102c by the locking component 201. A sealing component 202 is provided at the connection between the connector 102b and the diversion pipe 102c. When the connector 102b is connected to the diversion pipe 102c, it is guided and limited by the guide component 203.

[0050] Furthermore, the connector 102b includes a connecting pipe 102b-1 disposed at the end of the fixed pipe 102a and a limiting groove 102b-2 disposed in the connecting pipe 102b-1; wherein, the connecting pipe 102b-1 is provided with a locking component 201 through the limiting groove 102b-2, the connecting pipe 102b-1 is fixedly disposed at the end of the fixed pipe 102a, and multiple sets of limiting grooves 102b-2 are opened in the connecting pipe 102b-1, and each of the multiple sets of limiting grooves 102b-2 is provided with a locking component 201.

[0051] Furthermore, the engaging assembly 201 includes a slide rod 201a disposed in the limiting groove 102b-2, a locking block 201b disposed at the bottom of the slide rod 201a, a return spring 201c disposed on the outside of the slide rod 201a, and a stop block 201d disposed at the top of the slide rod 201a; wherein, the diverter pipe 102c has a locking groove 102d that mates with the locking block 201b, and when the diverter pipe 102c is inserted into the connecting pipe 102b-1, it can slide against the locking block 201b. At this time, the return spring 201c pushes the locking block 201b into the locking groove 102d. The limiting groove 102b-2 has a circular hole section P1 and a square section P2. The square section P2 is disposed below the circular hole section P1. The circular hole section P1 corresponds to the slide rod 201a, and the square section P2 corresponds to the locking block 201a. Corresponding to b, a return spring 201c is sleeved on the outside of the slide rod 201a. The two ends of the return spring 201c abut against the top of the square segment P2 of the locking block 201b and the limiting groove 102b-2, respectively. The locking block 201b is provided with a protrusion Y1 and a beveled part Y2, and the bottom of the beveled part Y2 of the locking block 201b is always in the limiting groove 102b-2. When the diverter pipe 102c is inserted into the connecting pipe 102b-1, the end of the diverter pipe 102c cooperates with the beveled part Y2 to push the locking block 201b to slide into the limiting groove 102b-2. When the diverter pipe 102c slides to the position corresponding to the locking block 201b in the locking groove 102d, the return spring 201c pushes the locking block 201b to reset and insert into the locking groove 102d, thereby fixing the diverter pipe 102c.

[0052] Furthermore, the sealing assembly 202 includes a first fixing ring 202a disposed on the inner wall of the connecting pipe 102b-1, a sealing ring 202b disposed on the first fixing ring 202a, and a second fixing ring 202c disposed on the inner wall of the diversion pipe 102c; wherein, after the diversion pipe 102c is connected to the connecting pipe 102b-1, it can compress the sealing ring 202b.

[0053] A first fixing ring 202a is fixedly provided on the inner wall of the connecting pipe 102b-1, and a sealing ring 202b is fixedly provided on one side of the first fixing ring 202a. A second fixing ring 202c is fixedly provided on the inner wall of the diversion pipe 102c, and the positions of the first fixing ring 202a and the second fixing ring 202c overlap. When the diversion pipe 102c is connected to the connecting pipe 102b-1, the spring continues to push the locking block 201b to move into the locking groove 102d, so that the protrusion Y1 enters the locking groove 102d, and then pushes the diversion pipe 102c to move, causing the second fixing ring 202c to squeeze the sealing ring 202b, so that the connection between the diversion pipe 102c and the fixing pipe 102a is sealed.

[0054] Furthermore, the guide assembly 203 includes an elongated block 203a disposed at the end of the connecting pipe 102b-1, a fixed plate 203b disposed outside the diversion pipe 102c, and a through groove 203c formed in the fixed plate 203b; wherein, the through groove 203c corresponds to the elongated block 203a, two sets of elongated blocks 203a are fixedly disposed at the end of the connecting pipe 102b-1, and a fixed plate 203b is fixedly disposed outside the diversion pipe 102c, and the fixed plate 203b has a through groove 203c corresponding to the elongated block 203a in the fixed plate 203b. When the diversion pipe 102c is connected to the connecting pipe 102b-1, the long blocks 203a correspond to the through groove 203c, so that the multiple sets of locking blocks 201b and locking slots 102d can be better aligned.

[0055] Operating Procedure: During use, the fixed pipe 102a is connected to the feed pipe F, and the diversion pipe 102c is connected to the grouting pipe K. When it is necessary to feed material into the grouting pipe K, the diversion pipe 102c is inserted into the connecting pipe 102b-1. The connecting pipe 102b-1 is rotated so that the long block 203a aligns with the through groove 203c. The end of the diversion pipe 102c contacts the inclined surface Y2 of the locking block 201b, pushing the locking block 201b to move. The moving locking block 201b compresses the return spring 201c. When the locking groove 102d moves to the position of the locking block... When 201b corresponds, the return spring 201c pushes the locking block 201b into the slot 102d. The return spring 201c continues to push the protrusion Y1 of the locking block 201b into the slot 102d, causing the diverter pipe 102c to slide continuously, which drives the second fixing ring 202c to squeeze the sealing ring 202b. This allows for quick installation by inserting the diverter pipe 102c into the connecting pipe 102b-1. By squeezing the sealing ring 202b, it seals the connection between the sealing ring 202b and the connecting pipe 102b-1, preventing material leakage.

[0056] Example 2

[0057] Reference Figure 1-6 This embodiment differs from the first embodiment in that it also includes an unlocking component 300, which includes,

[0058] A rotating ring 301 is provided on the outside of the connecting pipe 102b-1 and on the pushing member 302. The rotating ring 301 can drive the pushing member 302 to rotate. When the pushing member 302 rotates, it pushes the slide rod 201a to slide. The rotating ring 301 is sleeved on the outside of the connecting pipe 102b-1. The rotating ring 301 is provided with multiple sets of pushing members 302, and the number of sets of pushing members 302 corresponds to the slide rod 201a. The rotating ring 301 drives the pushing member 302 to rotate and push the slide rod 201a to move, which in turn drives the locking block 201b to disengage from the diversion pipe 102c. At this time, the diversion pipe 102c can be pulled to disengage from the connecting pipe 102b-1, so that the connecting pipe 102b-1 can be quickly disassembled and quickly connected to different diversion pipes 102c as needed.

[0059] Specifically, the pushing component 302 includes a movable block 302a disposed on the rotating ring 301, an elongated groove 302b formed on the movable block 302a, and a baffle 302c disposed on the movable block 302a; wherein, the elongated groove 302b corresponds to the slide rod 201a, the bottom of the baffle 201d abuts against the surface of the movable block 302a, and multiple sets of movable blocks 302a are fixedly disposed on the outer side of the rotating ring 301. The movable block 302a has an elongated groove 302b corresponding to the slide rod 201a. The top of both ends of the moving block 302a, which corresponds to the long groove 302b, is fixedly provided with baffles 302c. The moving block 302a is provided with an arc-shaped surface L, and both ends of the arc-shaped surface L are provided with flat parts. In the locked state, the stop block 201d is located on the lower flat part. When the rotating ring 301 rotates, the arc-shaped surface L and the stop block 201d abut against each other and push the slide rod 201a to slide. The slide rod 201a drives the locking block 201b to disengage from the locking groove 102d, so that the diversion pipe 102c can be disengaged from the connecting pipe 102b-1.

[0060] The rest of the structure is the same as in Example 1.

[0061] Operation process: During use, the fixed pipe 102a is connected to the feed pipe F, and the diversion pipe 102c is connected to the grouting pipe K. When it is necessary to feed material into the grouting pipe K, the diversion pipe 102c is inserted into the connecting pipe 102b-1. The connecting pipe 102b-1 is rotated so that the long block 203a aligns with the through groove 203c. The end of the diversion pipe 102c contacts the inclined surface Y2 of the locking block 201b, pushing the locking block 201b to move. The moving locking block 201b compresses the return spring 201c. When the locking groove 102d moves to the position of the locking block 201b... When block 201b corresponds, the return spring 201c pushes the block 201b into the slot 102d. The return spring 201c continues to push the protrusion Y1 of the block 201b into the slot 102d. The diversion pipe 102c continues to slide, causing the second fixing ring 202c to squeeze the sealing ring 202b. This allows for quick installation by inserting the diversion pipe 102c into the connecting pipe 102b-1. By squeezing the sealing ring 202b, it seals the connection between the sealing ring 202b and the connecting pipe 102b-1, preventing material leakage.

[0062] When it is necessary to disassemble the connecting pipe 102b-1 from the diverter pipe 102c, manually rotate the rotating ring 301. The rotating ring 301 drives the moving block 302a to rotate, and the limiting groove 102b-2 limits the sliding rod 201a. The arc-shaped part L of the moving block 302a abuts against the stop block 201d, causing the sliding rod 201a to slide upward, thereby causing the locking block 201b to disengage from the locking groove 102d. Pulling the diverter pipe 102c outward will disengage it from the connecting pipe 102b-1. When the diverter pipe 102c is disengaged from the connecting pipe 102b-1, the rotating ring 301 is released, and the return spring 201c pushes the locking block 201b to reset. At this time, the stop block 201d is driven to reset. During the reset process, the stop block 201d squeezes the arc surface L to reset the rotating ring 301, which makes it easy to remove the diverter pipe 102c. As needed, the connecting pipe 102b-1 can be connected to different diverter pipes 102c, so that the material can be transported to different grouting pipes K.

[0063] Example 3

[0064] Reference Figure 1-8 This embodiment differs from the above embodiments in that it also includes a plug-in component 400, which includes a movable ring 401, which is sleeved on one end of the rotating ring 301 and disposed between the rotating ring 301 and the movable ring 401; wherein, the movable component 402 can fix the position of the rotating ring 301, the movable ring 401 is slidably connected to the outside of the rotating ring 301, and the movable component 402 pushes the rotating ring 301 to slide and reset.

[0065] Specifically, the moving component 402 includes an insertion rod 402a disposed at the end of the moving ring 401, a limiting rod 402b disposed on the moving ring 401, and a push spring 402c disposed outside the limiting rod 402b; wherein, the fixed plate 203b has a square groove corresponding to the insertion rod 402a, the limiting rod 402b is connected to the rotating ring 301, the two ends of the push spring 402c abut against the rotating ring 301 and the moving ring 401 respectively, and the end of the moving ring 401 is connected to... Multiple sets of insert rods 402a are inserted into the square groove. When the insert rods 402a are inserted into the square groove, the insert rods 402a are located above the stop block 201d. A cavity is formed between the moving ring 401 and the rotating ring 301. The limiting rod 402b is located on one side of the moving ring 401 and in the cavity. A push spring 402c is sleeved on the outside of the limiting rod 402b. The limiting stroke is longer than the stroke of the slide rod 201a. The push spring 402c abuts against the insert rods 402a and inserts into the square groove to fix the position of the rotating ring 301.

[0066] The rest of the structure is the same as in Example 2.

[0067] Operating Procedure: During use, the fixed pipe 102a is connected to the feed pipe F, and the diversion pipe 102c is connected to the grouting pipe K. When it is necessary to feed material into the grouting pipe K, pull the moving ring 401 to move the insertion rod 402a away from the square groove, then insert the diversion pipe 102c into the connecting pipe 102b-1. Rotate the connecting pipe 102b-1 so that the long block 203a aligns with the through groove 203c. The end of the diversion pipe 102c contacts the inclined surface Y2 of the locking block 201b, pushing the locking block 201b to move. The moving locking block 201b compresses the return spring 201c. When the locking groove 102d moves to correspond with the locking block 201b, the return spring 201c... Push the card block 201b into the card slot 102d. The return spring 201c continuously pushes the protrusion Y1 of the card block 201b into the card slot 102d. The diversion pipe 102c continuously slides, causing the second fixing ring 202c to squeeze the sealing ring 202b. After the slide rod 201a is reset, the moving ring 401 is released, so that the push spring 402c pushes to insert the insertion rod 402a into the square groove, thereby fixing the position of the rotating ring 301. The diversion pipe 102c can be quickly installed by inserting it into the connecting pipe 102b-1. By squeezing the sealing ring 202b, it seals the connection between the sealing ring 202b and the connecting pipe 102b-1 to prevent material leakage.

[0068] When it is necessary to disassemble the connecting pipe 102b-1 from the diverter pipe 102c, manually pull the moving ring 401 to disengage the insert rod 402a from the square groove and move it away from the stop block 201d. Then rotate the rotating ring 301, which drives the moving block 302a to rotate. The limiting groove 102b-2 limits the sliding rod 201a. The arc-shaped part L of the moving block 302a abuts against the stop block 201d, causing the sliding rod 201a to slide upward, thereby causing the locking block 201b to disengage from the locking groove 102d. Pulling the diverter pipe 102c outward will disengage it from the connecting pipe 102b-1. After the diverter pipe 102c disengages from the connecting pipe 102b-1, release the moving ring 401. The return spring 201c pushes the locking block 201b to reset. At this time, the stop block 201d is driven to reset. During the reset process, the stop block 201d presses the arc surface L to reset the rotating ring 301. During the reset process, the push spring 402c pushes the insert rod 402a to reset. Since the stroke of the limit rod 402b is longer than that of the slide rod 201a, after the stop block 201d is fully reset, the insert rod 402a slides from above and inserts into the square groove, which makes it easy to remove the diversion pipe 102c. As needed, the connecting pipe 102b-1 can be connected to different diversion pipes 102c, so that the material can be transported to different grouting pipes K. The insert rod 402a fixes the position of the rotating ring 301 and the slide rod 201a to prevent the jamming block 201b from loosening when subjected to collision or vibration.
