Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, and in particular to a connection device and a tunneling equipment having the same. Background Art

[0002] At present, when excavating inclined coal seams, a bridge transfer machine is usually used to cooperate with a tunneling machine for discharging. That is, the coal gangue generated during the excavation of the tunneling machine will be transported to the bridge transfer machine and then transported to the outside through the bridge transfer machine. This is because the bridge transfer machine has a height adjustment function, that is, when facing inclined coal seams with different inclination angles, the bridge transfer machine can adjust the height of its feed point to ensure that it can connect with the discharge port of the tunneling machine.

[0003] However, the above excavation method has the following three problems:

[0004] 1. The lifting angle of the bridge conveyor must be less than 20°. When the lifting angle exceeds 20°, the gangue will slip by itself during the transportation through the bridge conveyor, and the material cannot be transported. Therefore, a special tape with high friction resistance must be used to improve the conveyor belt of the bridge conveyor. The above operation not only increases the excavation cost, but also affects the excavation efficiency.

[0005] 2. When using a bridge-type loader to cooperate with the tunnel boring machine to discharge slag, the gantry height must be modified to the minimum, and the rear support must be raised to adjust the lifting angle. The above setting will affect the tunneling operation of the tunnel boring machine, resulting in lower tunneling efficiency;

[0006] 3. When the tunnel boring machine is excavating in an inclined coal seam, it needs to cooperate with the winch to assist in pulling the tunnel boring machine back and forth. During the traction process, the winch wire rope is very likely to interfere with the high-rise bridge-type transfer machine, causing scratches and damage to the equipment. Summary of the invention

[0031] In order to solve the problems in the prior art of high cost, low efficiency and equipment damage in the excavation method of inclined coal seams, the present application provides a connection device and excavation equipment having the same.

[0032] like Figure 1 As shown, the connection device is arranged on the traction beam 101 of the tunnel boring machine 1, and the connection device includes: a support seat 10; a trough assembly 20, including a trough body 21 and a lap portion 22, the feed end 211 of the trough body 21 is connected with the discharge port of the tunnel boring machine 1, the lap portion 22 is arranged on the discharge end 212 of the trough body 21, so as to be overlapped on the scraper conveyor 3, and at least part of the lap portion 22 is made of flexible material; the discharge end 212 is located below the feed end 211, so that the material slides to the scraper conveyor 3 along the extension direction of the trough body 21 under the action of its own gravity. Among them, the trough assembly 20 is flippably arranged on the support seat 10, and the height difference between the feed end 211 and the discharge end 212 is adjusted by adjusting the flip angle of the trough assembly 20.

[0033] The technical solution of this embodiment is applied, and the connection device is arranged on the traction beam 101 of the tunnel boring machine 1 and includes a support seat 10, the feed end 211 of the trough body 21 of the trough assembly 20 is connected with the discharge port of the tunnel boring machine 1, and the overlap portion 22 is arranged on the discharge end 212 of the trough body 21 for overlapping on the scraper conveyor 3, at least part of the overlap portion 22 is made of flexible material, and the discharge end 212 is located below the feed end 211 so that the material slides to the scraper conveyor 3 along the extension direction of the trough body 21 under the action of its own gravity. Among them, the trough assembly 20 is flippably arranged on the support seat 10, and the height difference between the feed end 211 and the discharge end 212 is adjusted by adjusting the flip angle of the trough assembly 20. In this way, this embodiment actually abandons the bridge-type transfer machine that can be adjusted in height in the prior art. While using a conventional scraper conveyor 3 to transport materials, a connecting device is set on the tunneling machine 1 to realize the transportation of materials between the tunneling machine 1 and the scraper conveyor 3. The trough-shaped main body 21 of the connecting device can realize the "self-sliding" (material transportation) of the material, and can adjust the height difference between the feed end 211 and the discharge end 212 by adjusting the flip angle of the trough-shaped main body 21. At the same time, the overlapping part 22 made of flexible material can also undergo corresponding deformation, so as to adapt to coal seams with different inclination angles and ensure that the material can be stably transported to the scraper conveyor 3. Therefore, this embodiment achieves the angle lifting function of the bridge-type transfer machine through the cooperation between the connecting device and the scraper conveyor 3, and the material conveying function of the scraper conveyor will not be affected by the inclination angle, thereby avoiding the problems of increased cost, reduced efficiency and scratch damage to equipment caused by the bridge-type transfer machine, thereby solving the problems of high cost, low efficiency and equipment damage in the prior art of tunneling in inclined coal seams.

[0034] In this embodiment, the material is coal gangue.

[0035] Specifically, in the process of retreating the tunnel boring machine with the assistance of a winch, the staff can also operate the trough component 20 to flip it so as to avoid the steel wire rope of the winch, thereby further avoiding equipment damage caused by the steel wire rope scratching the equipment.

[0036] Specifically, the traction beam 101 of the tunnel boring machine 1 is also the position where the wire rope is connected during the process of the winch assisting in pulling the tunnel boring machine back. The staff can operate the trough component 20 to flip it to avoid the wire rope of the winch.

[0037] like Figure 1 As shown, the connection device further includes a connection assembly 30, which includes: a first connection member 31, which is arranged on the groove-shaped body 21; and a second connection member 32, which is arranged on the support seat 10. The first connection member 31 and the second connection member 32 are rotatably connected, so that the groove-shaped body 21 can be flipped on the support seat 10. In this way, the above arrangement realizes the flip connection between the groove-shaped body 21 and the support seat 10 through the rotational cooperation between the first connection member 31 and the second connection member 32.

[0038] In this embodiment, the trough-shaped body 21 is turned over in the height direction to adapt to inclined coal seams with different inclination angles.

[0039] In this embodiment, the first connecting member 31 has a first penetration hole, and the second connecting member 32 has a first connecting end 321, and the first connecting end 321 is rotatably penetrated in the first penetration hole. In this way, the above arrangement makes the rotational cooperation between the first connecting member 31 and the second connecting member 32 simpler, easier to process and realize, thereby reducing the processing difficulty and processing cost of the two.

[0040] In this embodiment, the first connecting member 31 is actually in a cylindrical shape and is integrally welded to the bottom surface of the groove-shaped main body 21 , while the first connecting end 321 is in a columnar shape.

[0041] In this embodiment, the second connecting member 32 also has a second connecting end 322, and the connecting assembly 30 also includes: a third connecting member 33, which is arranged on the support seat 10 and has a second through hole, and the second connecting end 322 is rotatably inserted into the second through hole; wherein the rotation axis of the first connecting end 321 and the rotation axis of the second connecting end 322 are arranged at a first angle. In this way, the above arrangement enables the groove-shaped body 21 to have another degree of freedom of rotation adjustment, that is, the groove-shaped body 21 is adjusted to a tilted state, so as to further increase the posture adjustment range of the groove-shaped body 21, and further avoid the problem of equipment scratches caused by the wire rope.

[0042] In this embodiment, the rotation axis of the second connection end 322 and the rotation axis of the first connection end 321 are arranged at 90°.

[0043] In this embodiment, the third connecting member 33 is cylindrical.

[0044] Optionally, threaded holes connected to the inner holes of the first connecting member 31 and the third connecting member 33 may be provided, and locking bolts may be additionally provided so that after the staff adjusts the slot component 20 to a corresponding angle, the first connecting end 321 and the second connecting end 322 may be locked by the locking bolts to fix the angle of the slot component 20.

[0045] Optionally, the support seat 10 may also be provided with a driving device, such as a driving cylinder or a servo motor, that is, the driving device is used to drive the groove-shaped body 21 to flip.

[0046] Specifically, the second connection end 322 is a columnar structure. In fact, the staff can weld a plurality of columnar structures at the construction site to form the second connection member 32.

[0047] like Figure 1 As shown, the support seat 10 includes: a support body 11, having at least two mounting parts 111, and a turning space is formed between the at least two mounting parts 111; a mounting rod 112, which is passed through the at least two mounting parts 111, and a third connecting member 33 is arranged on the mounting rod 112; wherein at least part of the groove-shaped body 21 is located in the turning space, and the turning space is used to avoid the groove-shaped body 21 during the turning process of the groove-shaped body 21. In this way, while providing a mounting position for the third connecting member 33 through the mounting rod 112, the setting of the turning space can avoid the turning action of the groove-shaped body 21, so as to avoid mutual interference between the support seat 10 and the groove-shaped body, thereby improving the turning stability of the groove-shaped body 21.

[0048] In this embodiment, a mounting plate 114 is further provided on the mounting rod 112, and the mounting plate 114 is mounted on the mounting rod 112 by U-bolts, and the third connecting member 33 is welded to the mounting plate 114. In this way, the above arrangement can increase the welding area of ​​the third connecting member 33 and improve its installation reliability.

[0049] In this embodiment, the mounting portion 111 is plate-shaped, and the support seat 10 further includes: a base 113, and at least two mounting portions 111 are arranged on the base 113. Among them, the base 113 is rotatably arranged on the traction beam 101. In this way, the above arrangement makes the structure of the support seat 10 simpler and easier to process, thereby reducing the processing cost of the support seat 10; on the other hand, the support seat 10 and the groove-shaped component 20 can be rotated as a whole, so that the connection device as a whole can avoid the wire rope, further avoiding the problem of equipment scratches caused by the wire rope.

[0050] like Figure 1 As shown, the connection device further includes: a rotating member 40, which is inserted through the traction beam 101 and the base 113, and the base 113 is rotatably connected to the traction beam 101 through the rotating member 40, wherein the rotation axis of the rotating member 40 is set at a second angle to the flip axis of the groove-shaped body 21. In this way, the above setting realizes the rotation of the support seat 10 through the rotating member 40 on the one hand; on the other hand, the setting of the rotation axis can increase the rotation adjustment range of the connection device, so as to further ensure that the connection device can avoid the wire rope.

[0051] In this embodiment, the rotating member 40 is a pin shaft.

[0052] In this embodiment, the rotation axis of the rotating member 40 and the flip axis of the groove-shaped body 21 are perpendicular to each other, and the rotation axis of the rotating member 40 and the rotation axis of the second connecting end 322 are located in the same plane and form a third angle therebetween.

[0053] In this embodiment, the connection device also includes: a clamping assembly, including a first clamping structure and a second clamping structure, the first clamping structure is arranged on the base 113, the second clamping structure is arranged on the traction beam 101, one of the first clamping structure and the second clamping structure is a protrusion, the other of the first clamping structure and the second clamping structure is a recess, the protrusion extends into the recess and is clamped with the recess; wherein the first clamping structure rotates synchronously with the base 113, and when the base 113 rotates to a preset angle, the first clamping structure and the second clamping structure are clamped. In this way, when the staff rotates the support seat 10, the support seat 10 can be fixed by the clamping cooperation between the first clamping structure and the second clamping structure bracket, thereby preventing the support seat 10 from shaking during the retreat of the tunnel boring machine 1, which causes it to rub against the wire rope.

[0054] It should be noted that the specific structure of the snap-fit ​​assembly will not be described in detail, and a common snap-fit ​​structure will suffice.

[0055] In this embodiment, the trough-shaped body 21 includes a bottom plate 213 and two side plates 214 disposed on the bottom plate 213. The side plates 214 have guide sections. The distance between the guide sections of the two side plates 214 gradually decreases along the direction from the feed end 211 to the discharge end 212. In this way, the above arrangement makes the size of the feed end 211 larger to prevent the material from falling outside the trough-shaped body 21. At the same time, the above arrangement can also improve the smoothness of the flow of the material.

[0056] Specifically, the overall processing of the connecting device in this embodiment is simple and the materials are easy to obtain. That is, the workers can use the materials on site to quickly process the connecting device at the construction site. The overall cost is low and the use is reliable. The specific dimensions can be modified accordingly according to the dimensions of the tunnel boring machine 1 to complete the overall improvement of the tunnel boring equipment at the construction site.

[0057] like Figure 2 As shown, this embodiment further provides a tunneling device, which includes a tunneling machine 1, a connection device 2 and a scraper conveyor 3. The connection device 2 is arranged on the tunneling machine 1. The connection device 2 connects the discharge port of the tunneling machine 1 and the scraper conveyor 3 to realize the transportation of materials between the tunneling machine 1 and the scraper conveyor 3. Among them, the connection device 2 is the above-mentioned connection device.

[0058] In this embodiment, the tunnel boring machine 1 is a cantilever tunnel boring machine.

[0059] Specifically, the tunnel boring machine 1 in this embodiment does not need to adopt the traditional tunnel boring machine 1 retreating method. After the tunnel boring machine 1 cuts and falls coal, it slides into the scraper conveyor 3 through the connecting device 2, and then enters the coal flow line of the back lane. When the winch pulls the tunnel boring machine 1 backward, the wire rope head is connected to the traction beam 101, and the angle of the connecting device 2 and the flip angle of the groove-shaped main body 21 are adjusted synchronously. The winch is started to pull the tunnel boring machine 1, and the tunnel boring machine 1 is retreated synchronously. After the tunnel boring machine 1 is retreated to the bottoming position, the tunnel boring machine 1 descends to bottom, and the winch loosens the rope as the tunnel boring machine 1 descends. This solves the problem that when a bridge-type transfer machine is used for material transportation, the tunnel boring machine 1 cannot go up and then go down to bottom when facing an inclined coal seam with an inclination angle exceeding ±18°.

[0060] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0061] The connection device is arranged on the traction beam of the tunnel boring machine and includes a support seat, the feed end of the trough body of the trough assembly is connected with the discharge port of the tunnel boring machine, the overlap portion is arranged on the discharge end of the trough body for overlapping on the scraper conveyor, at least part of the overlap portion is made of flexible material, and the discharge end is located below the feed end so that the material slides along the extension direction of the trough body to the scraper conveyor under the action of its own gravity. The trough assembly can be flipped on the support seat, and the height difference between the feed end and the discharge end can be adjusted by adjusting the flip angle of the trough assembly. In this way, the present application actually abandons the bridge-type transfer machine that can be adjusted in height in the prior art. While using a conventional scraper conveyor to transport materials, a connecting device is set on the tunneling machine to realize the transportation of materials between the tunneling machine and the scraper conveyor. The trough-shaped main body of the connecting device can realize the "self-sliding" of materials (material transportation) while adjusting the flipping angle of the trough-shaped main body to adjust the height difference between the feed end and the discharge end. At the same time, the lap joint made of flexible material can also undergo corresponding deformation to adapt to coal seams with different inclination angles and ensure that materials can be stably transported to the scraper conveyor. Therefore, the present application achieves the angle lifting function of the bridge-type transfer machine through the cooperation between the connecting device and the scraper conveyor, and the material conveying function of the scraper conveyor will not be affected by the inclination angle, thereby avoiding the problems of increased cost, reduced efficiency and scratch damage to equipment brought by the bridge-type transfer machine, thereby solving the problems of high cost, low efficiency and equipment damage in the prior art excavation method of inclined coal seams.
