Description

Technical Field

[0001] This invention belongs to the field of coal mine tunnel drilling technology, and relates to a stable column assembly, specifically a plug-in rod, a top plate, and a loading and unloading device for a tunnel drilling rig. Background Technology

[0002] like Figure 1 As shown, during tunnel drilling, vertically supported columns are typically used to stabilize the rig. These columns are installed at the four corners of the rig's body. In operation, the upper end of the column presses against the tunnel roof, and the lower end presses against the tunnel floor. The column consists of a double-acting hydraulic cylinder, connectors, plug-in rods, and a top-mounting plate. The plug-in rods are connected to each other and to the top-mounting plate via plug-in joints. The plug-in rods are of fixed length, typically 400mm, 600mm, or 1000mm. The number of plug-in rods installed varies depending on the tunnel height at the construction site. Installation of the plug-in rods is entirely manual. When the tunnel height exceeds 3 meters, installation requires working at height. Due to the significant weight of the plug-in rods, the installation process is time-consuming, labor-intensive, and inherently dangerous. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a connector rod, top plate and loading / unloading device for tunnel drilling rigs, so as to solve the safety problems and high labor intensity problems faced by manual drilling rig stabilization in the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A plug-in rod includes an integrally formed narrow-diameter tube and a wide-diameter tube. The upper end of the wide-diameter tube is provided with a boss to form a plug-in rod with a boss. The boss can cooperate with a stop in a slip device to lock the plug-in rod with a boss.

[0006] The slip device described herein is the slip device used in the loading and unloading device described below.

[0007] The present invention also protects a connector, including an inner tube, the lower end of which is fitted inside an outer tube, and the inner tube is capable of telescopic movement within the outer tube; a return spring is installed inside the outer tube, the upper end of which rests against the lower end of the inner tube, and the lower end of which rests against the lower end of the outer tube.

[0008] The inner tube has a strip-shaped hole along the axial direction on its side wall. A limiting pin passes through the strip-shaped hole radially and is fixed to the side wall of the outer tube, thereby limiting the extension and retraction of the inner tube within the outer tube.

[0009] The upper end of the inner tube is provided with a boss to form a top plate with a boss. The boss can cooperate with the stop block in the slide to realize the picking and putting of the top plate with a boss.

[0010] The slip device described herein is the slip device used in the loading and unloading device described below.

[0011] Both the upper end of the inner tube and the upper end of the outer tube are provided with a tapered column.

[0012] The present invention also protects a loading and unloading device, comprising a base, multiple extension rods, a roller beam frame, and a slip device.

[0013] The aforementioned slip device includes a hollow notch base, which is detachably connected to the bottom of the notch housing. A notch inclined slip guide plate is fixedly connected inside the notch housing, and a guide plate is connected to the lower end of the notch inclined slip guide plate. A pair of coaxially arranged guide cylinders that enable the extension and retraction of the pin are fixedly arranged along the radial direction on the notch housing. Electromagnetic pins are installed in the guide cylinders respectively. The notch housing and the guide plate are provided with through holes that allow the electromagnetic pins to pass through. The on and off of the current can control the extension and retraction of the electromagnetic pins.

[0014] The notched base includes a base with a notch, a support is provided on the base, and a stop and a torsion spring are installed on the support through a threaded pin. When no external force is applied, the torsion spring can restore the rotated stop to its initial state.

[0015] The base has an arc-shaped locking hook that can move circumferentially within a circumferential annular track. The circumferential movement of the locking hook can enter a notch on the base to lock the notch.

[0016] The base is equipped with two electromagnetic adsorption blocks, which can respectively adsorb the handles at both ends of the locking hook, so that the locking hook can enter the notch on the base or retract into the annular track inside the base.

[0017] The base includes a frame with a plug-in plate at the bottom, and a winch, guide tube and gear assembly are fixedly installed on the top of the frame.

[0018] The connection between the guide tube and the frame, as well as the lower end connecting plate of the frame, are provided with a central through hole. The central through hole is connected to the guide tube, and the extension rod passes through the central through hole and is inserted into the hollow guide tube.

[0019] The extension rod includes a circular tube open at both ends, which is divided into an integrally formed upper large-diameter tube section and a lower small-diameter tube section. Adjacent extension rods are connected by inserting the large-diameter tube section and the small-diameter tube section. A rack is fixedly installed axially on the outer wall of the large-diameter tube section. A limiting groove is opened on the side of the guide tube. The rack is engaged in the limiting groove so that the extension rod can only move axially up and down in the guide tube. The gear in the gear assembly meshes with the rack, and the vertical lifting and lowering of the extension rod is realized under the drive of the gear assembly.

[0020] The roller beam frame includes a beam frame outer sleeve, with a connector at the lower left end of the outer sleeve that inserts into the larger diameter pipe section at the top of the extension rod; a telescopic inner sleeve is installed inside the outer sleeve, and a hydraulic cylinder is installed between the outer and inner sleeves, driving the telescopic movement between them; rollers are respectively installed at the outer ends of the outer and inner sleeves, and the winch's wire rope passes around the two rollers and suspends the slip device.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] (I) The present invention uses a stable column assembly loading and unloading device to replace manual loading and unloading of the plug rod and the top plate, which solves the problems of high labor intensity and high risk of working at height.

[0023] (II) The conical column provided on the upper end of the top plate with protrusion in this invention increases the friction between the top plate and the top plate, making it more stable and reliable.

[0024] (III) The slip device of the present invention is equipped with an electromagnetic pin and a locking hook, so that the slip and fall will not occur during the transportation of the plug rod and the top plate, making it safer to use. Attached Figure Description

[0047] The specific content of the present invention will be further explained in detail below with reference to the embodiments. Detailed Implementation

[0048] It should be noted that, unless otherwise specified, all components in this invention are components known in the prior art.

[0049] The existing technology is as follows:

[0050] like Figure 1 As shown, four columns 2 are installed at the four corners of the tracked vehicle body 1. Each column 2 consists of a stabilizing cylinder 3, a conversion joint 4, several connecting rods 5, and a top-mounting plate 6. After all parts are connected, high-pressure oil is introduced into the stabilizing cylinder 3, driving it to tighten the column. The number of connecting rods 5 varies depending on the tunnel height. The top-mounting plate 6 is connected to the uppermost connecting rod 5. Its function is to increase the contact area between the column 2 and the roof, making the column 2 more stable and secure.

[0051] like Figure 2 As shown, the connector 5 consists of a narrow-diameter tube 7, a handle 8, and a wide-diameter tube 9. The inner diameter of the wide-diameter tube 9 is the same as the outer diameter of the narrow-diameter tube 7. When multiple connectors 5 are connected, the narrow-diameter tube 7 of the next connector 5 is inserted into the wide-diameter tube 9 of the previous connector 5, and so on.

[0052] like Figure 3 As shown, the top plate 6 consists of a connector 10 and a plate body 11. The connector 10 can be inserted into the large-diameter tube body 9 of the connector rod 5.

[0053] In view of the fact that existing technologies require manual installation of splice rods and top plates when the tunnel is high, resulting in high risk of working at height and high labor intensity, this invention provides a splice rod, top plate, and loading / unloading device for tunnel drilling rigs.

[0054] The present invention provides bosses at the upper ends of both the connector rod and the top plate for connection with the loading and unloading device. The loading and unloading device includes a base, an extension rod, a roller beam frame, and a slipper. The base supports the entire loading and unloading device and functions to install the extension rod and lift the slipper. The extension rod raises and lowers the height of the roller beam frame. The roller beam frame guides the wire rope lifting the slipper and functions to translate the slipper. The slipper is used to hold the extension rod and the top plate. Using the loading and unloading device of the present invention, the connector rod and the top plate can be loaded and unloaded mechanized in situations with high roadway heights, reducing the labor intensity of workers and avoiding the safety hazards of working at heights.

[0055] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0056] Example 1:

[0057] This embodiment provides a connector rod, comprising an integrally formed narrow-diameter tube 7 and a wide-diameter tube 9, such as... Figure 4 As shown, a boss 42 is provided at the upper end of the large-diameter pipe body 9, forming a bossed plug rod 49; the boss 42 can cooperate with the stop block 38 in the slipper 15 to lock the bossed plug rod 49.

[0058] As a preferred embodiment, the slip device 15 is the slip device 15 in the loading and unloading device given in Embodiment 3.

[0059] Example 2:

[0060] This embodiment provides a plug-in plate, such as Figure 5 As shown, it includes an inner tube 43, the lower end of which is fitted inside an outer tube 47, and the inner tube 43 can extend and retract within the outer tube 47; a return spring 46 is installed inside the outer tube 47, the upper end of which rests against the lower end of the inner tube 43, and the lower end of which rests against the lower end inside the outer tube 47.

[0061] A strip-shaped hole 48 is provided on the side wall of the inner tube 43 along the axial direction. A limiting pin 45 passes through the strip-shaped hole 48 radially. The limiting pin 45 is fixed on the side wall of the outer tube 47 to limit the extension and retraction stroke of the inner tube 43 in the outer tube 47.

[0062] Specifically, under no external force, the spring force of the return spring 46 pushes the inner tube 43 to its uppermost position, and the limiting pin 45 contacts the lower end of the strip hole 48. When the new type of roof receiving plate is installed in the column and is pressed against the roadway roof by the stabilizing cylinder 3, the inner tube 43 retracts into the outer tube 47.

[0063] The upper end of the inner tube 43 is provided with a boss 42, forming a boss-top plate 50. The boss 42 can cooperate with the stop block 38 in the slipper 15 to realize the picking and putting of the boss-top plate 50.

[0064] As a preferred embodiment, the slip device 15 is the slip device 15 in the loading and unloading device given in Embodiment 3.

[0065] As a preferred embodiment, the top plate 50 with a boss and the plug-in rod 49 with a boss given in Embodiment 1 are connected by a plug-in method.

[0066] As a preferred embodiment, both the upper end of the inner tube 43 and the upper end of the outer tube 47 are provided with a tapered column 44, which is used to increase the friction between the roof support plate and the roadway roof.

[0067] Example 3:

[0068] This embodiment provides a loading and unloading device, such as... Figure 6 and Figure 7 As shown, it consists of a base 12, multiple extension rods 13, a roller beam frame 14, and a slip device 15.

[0069] like Figure 8 and Figure 9 As shown, the base 12 includes a frame 17 with a plug plate 16 at the bottom, and a winch 18, a guide tube 19 and a gear assembly 20 are fixedly installed on the top of the frame 17.

[0070] like Figure 6 and Figure 7 As shown, the connection between the guide tube 19 and the frame 17, as well as the lower end connecting plate of the frame 17, are provided with a central through hole. The central through hole is connected to the guide tube 19, and the extension rod 13 passes through the central through hole and is inserted into the hollow structure of the guide tube 19.

[0071] In this embodiment, when the base 12 is in use, the plug-in plate 16 is bolted to the side of the tracked vehicle body 1. The loading and unloading device can be securely installed by inserting the legs of the frame 17 into the grooves of the plug-in plate 16.

[0072] like Figure 10 As shown, the extension rod 13 includes a circular tube 21 with open ends. The circular tube 21 is divided into an integrally formed upper large-diameter tube section and a lower small-diameter tube section. Two adjacent extension rods 13 are connected by inserting the large-diameter tube section and the small-diameter tube section. A rack 22 is fixedly provided on the outer wall of the large-diameter tube section along the axial direction. A limit groove is opened on the side of the guide tube 19. The rack 22 is installed in the limit groove so that the extension rod 13 can only move axially up and down in the guide tube 19. The gear in the gear assembly 20 meshes with the rack 22, and the vertical lifting and lowering of the extension rod 13 is realized under the drive of the gear assembly 20.

[0073] Preferably, both the large-diameter pipe section and the small-diameter pipe section are provided with pin holes 23, which are used for plug-in connection and then positioning by pin.

[0074] like Figure 11 and Figure 12 As shown, the roller beam frame 14 includes a beam frame outer sleeve 27. A connector 24 is provided at the lower left end of the beam frame outer sleeve 27. The connector 24 is inserted into the large-diameter pipe section at the upper part of the extension rod 13. A beam frame inner sleeve 28 is telescopically installed inside the beam frame outer sleeve 27. A hydraulic cylinder 29 is installed between the beam frame outer sleeve 27 and the beam frame inner sleeve 28. The hydraulic cylinder 29 drives the telescopic movement between the beam frame outer sleeve 27 and the beam frame inner sleeve 28. Rollers 26 are respectively provided at the outer ends of the beam frame outer sleeve 27 and the outer ends of the beam frame inner sleeve 28. The wire rope of the winch 18 passes around the two rollers 26 and suspends the slip device 15.

[0075] Preferably, the insertion tube 24 is provided with a second pin hole 25, through which a pin passes through the pin hole 23 and the second pin hole 25.

[0076] like Figure 13 , Figure 14 and Figure 15 As shown, the slip unit 15 includes a hollow notch base 30, which is detachably connected to the bottom of the notch housing 32. A notch inclined slip guide plate 34 is fixedly connected inside the notch housing 32. A guide plate 35 is connected to the lower end of the notch inclined slip guide plate 34. A pair of coaxially arranged guide cylinders that enable the pin to extend and retract are fixedly arranged along the radial direction on the notch housing 32. Electromagnetic pins 31 are respectively installed in the guide cylinders. The notch housing 32 and the guide plate 35 are provided with through holes that allow the electromagnetic pins 31 to pass through. The on and off of the current can control the extension and retraction of the electromagnetic pins 31.

[0077] As a preferred embodiment, the notched base 30 and the notched housing 32 are detachably connected by threads.

[0078] As a preferred embodiment, the notch inclined guide plate 34 is a baffle with an arc-shaped curved surface.

[0079] As a preferred embodiment, a lifting ring assembly 33 is provided on the top of the notch housing 32, and the lifting ring assembly 33 is connected to the wire rope of the winch 18.

[0080] like Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the notched base 30 includes a notched base 36, on which a support is mounted. A stop 38 and a torsion spring 39 are threaded through the support via a threaded pin 37. When no external force is applied, the torsion spring 39 allows the rotated stop 38 to return to its initial state. Specifically, under external force, the stop 38 can rotate within a certain range around the threaded pin 37, while the torsion spring 39 deforms under stress. When no external force is applied, the stop 38 returns to its initial state under the restoring force of the torsion spring 39. Figure 16 The location shown.

[0081] Inside the base 36, along a circumferential annular track, is an arc-shaped locking hook 41 that can move circumferentially. The circumferential movement of the locking hook 41 can enter the notch on the base 36 to lock the notch.

[0082] In a preferred embodiment, the base 36 is provided with two electromagnetic adsorption blocks 40. These blocks can respectively adsorb the handles at both ends of the hook 41, allowing the hook 41 to enter the notch on the base 36 or retract into the annular track within the base 36. Specifically, when one of the electromagnetic adsorption blocks 40 is energized, the handle of the hook 41 will be adsorbed onto it. When the hook 41 is adsorbed onto the electromagnetic adsorption block 40 at the upper end of the base 36, the notched base 30 is in an open state; when the hook 41 is adsorbed onto the electromagnetic adsorption block 40 at the right end of the base 36, the notched base 30 is in a locked state.

[0083] Example 4:

[0084] This embodiment provides a method for attaching and removing connecting rods and top plates using an attachment / removal device. When using the attachment / removal device provided in Embodiment 3 to attach and remove the protruding connecting rod 49 from Embodiment 1 and the protruding top plate 50 from Embodiment 2, the attachment / removal device is placed near the column 2. The attachment / removal device has the function of lifting the protruding connecting rod 49 and the protruding top plate 50 from the ground and attaching them to the column 2, and also has the function of lifting the protruding connecting rod 49 and the protruding top plate 50 from the column 2 and transporting them to the ground. By attaching different numbers of extension rods 13, the roller beam frame 14 can be lifted to a certain height, and under the action of the winch 22, the protruding connecting rod 49 and the protruding top plate 50 can be transported to a designated height.

[0085] like Figure 20 As shown, when the slipper 15 is locked with the protruding connector 49, the electromagnetic pin 31 in the slipper 15 is in the extended state, the locking hook 41 is in the locked state, and the protruding connector 49 will not slip off or fall off.

[0086] like Figure 21 As shown, when the slipper 15 is locked in place with the boss on the top plate 50, the electromagnetic pin 31 in the slipper 15 is in an extended state, and the locking hook 41 is in a locked state, the boss on the top plate 50 will not slip off or fall off.

[0087] According to the above technical solution, the process of adding the bossed plug-in rod 49 and the bossed top plate 50 is as follows:

[0088] Step 1: The plug plate 16 is bolted to the side of the tracked vehicle body 1. The lower support leg of the frame base 12 is inserted into the plug plate 16. A certain number of extension rods 13 are added to the loading and unloading device so that the height that the slipper 15 can be raised meets the needs of adding the plug rod 49 with the boss and the top plate 50 with the boss.

[0089] Step 2: An adapter 4 is installed on the stabilizing cylinder 3 of the drilling rig column.

[0090] Step 3: Place the plug rod 49 with the boss directly below the slipper 15, and control the winch 18 to slowly lower the slipper 15. Under the gravity of the slipper 15, the boss 42 pushes against the stop block 38 and rotates the stop block 38 at a certain angle. After the boss 42 passes through the stop block 38, the stop block 38 returns to its original position. Lift the slipper 15 so that the lower end of the boss 42 contacts the upper surface of the stop block 38, and then lock the electromagnetic pin 31 and the locking hook 41.

[0091] Step 4: Raise the plug rod 49 with the boss to the required height, extend the cylinder 29 in the roller beam frame 14, and move the slipper 15 along with the plug rod 49 with the boss to directly above the column. Lower the slipper 15 so that the plug rod 49 with the boss is inserted into the column. Retract the electromagnetic pin 31 and the locking hook 41. Continue to lower the slipper 15. The notch guide plate 34 in the slipper 15 slides relative to the boss 42. The slipper 15 disengages from the column through the notch on the notch base 30 and the notch shell 32. Retract the cylinder 29 in the roller beam frame 14 and lower the slipper 15 using the winch 18.

[0092] Step 5: Repeat steps 3 and 4 until the required number of bossed plug-in rods 49 are added. If the lifting height of the slipper 15 is insufficient during the addition process, an extension rod 13 can be added to the addition and removal device to increase the lifting height of the slipper 15.

[0093] Step six: Install the top plate 50 with the protrusion into the slipper 15, control the loading and unloading device to insert the top plate 50 with the protrusion into the top of the column, and control the slipper 15 to return to the initial position.

[0094] Step 7: Control the extension of the stabilizing cylinder rod 3 to tighten the column.

[0095] Step 8: Repeat steps 1 through 7 to complete the stabilization of the four columns of the drilling rig.

[0096] According to the above technical solution, the process of disassembling the bossed connector rod 49 and the bossed top plate 50 is as follows:

[0097] Step 1: Insert the lower support leg of the frame base 12 into the plug plate 16 connected to the tracked vehicle body, and add a certain number of extension rods 13 to the loading and unloading device so that the height that the slipper 15 can be raised meets the needs of adding the plug rod 49 with the boss and the top plate 50 with the boss.

[0098] Step 2: Control the retraction of the cylinder rod of the stabilizing cylinder 3. The column assembly at the upper end of the cylinder rod descends a certain distance, and the top plate 50 with the boss detaches from the top plate. Under the action of the return spring 46, the inner tube 43 extends out from the outer tube 47.

[0099] Step 3: Control the loading and unloading device to remove the top plate 50 with the boss and place it on the ground.

[0100] Step 4: Control the loading and unloading device to remove all the plug-in rods 49 with protrusions and place them on the ground.

[0101] Step 5: Repeat steps 1 to 4 to complete the disassembly of the four column assemblies of the drilling rig.
