Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically to a pre-unloading skip for long-distance, large-section, gently sloping inclined shaft construction in complex environments. Background Technology

[0002] A skip is a container that directly loads useful minerals, waste rock, or gangue. It is mainly used for hoisting operations in mines and can be divided into two types: those for inclined shafts and those for vertical shafts. It is classified according to different hoisting methods and unloading methods. Bottom-discharge skips are commonly used in coal mine vertical shafts, while front-discharge, rear-discharge, and tipping skips are commonly used in inclined shafts. Among them, the front-discharge skip is hoisted to the unloading position, and then the rear of the skip box is lifted by the curved rail, causing the skip box to tilt forward and unload the ore from the opening at the front of the skip box.

[0003] When transporting ore, a traction rope is typically used to pull the front-discharge skip along the running track of the inclined shaft. However, due to the complex environment inside the inclined shaft and the long running distance, gaps may exist between the running tracks, causing the front-discharge skip to easily bounce during transportation. In such cases, larger pieces of ore may roll off and become stuck on the running track, thus jamming the front-discharge skip. (Based on application publication number CN 115285818) Patent application A discloses a front-discharge inclined shaft skip. By incorporating a buffer device, the tension on the first traction rope can be cushioned, avoiding the risk of rope breakage and ensuring stability during transport. However, the existing technology has the following shortcomings: Although the buffer device can prevent rope breakage to some extent, if ore gets stuck between the running track and the rollers at the bottom of the front-discharge skip, and the traction equipment continues to pull the skip via the traction rope, the rope may break, causing the skip to slide rapidly along the running track towards the bottom of the inclined shaft, potentially leading to a safety accident. Secondly, the discharge gate is installed on the bottom wall of the discharge port via a fixed seat and a mandrel. During discharge, the gate can only open outward around the mandrel to the bottom right side of the discharge port, and gravel may get stuck between the fixed seat and the mandrel, affecting the gate's usability. Therefore, we propose a front-discharge inclined shaft skip for long-distance, large-section, gently sloping inclined shaft construction in complex environments.

[0004] Combining the above issues, we find that existing products on the market are difficult to avoid all of these problems simultaneously. Even if they can be solved, they require external tools, which fails to achieve the desired results. Therefore, we propose a pre-unloading skip for long-distance, large-section, gently sloping inclined shaft construction in complex environments. Summary of the Invention

[0005] The purpose of this invention is to provide a pre-unloading skip for long-distance, large-section, gently sloping inclined shaft construction in complex environments, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-unloading inclined shaft skip for construction of long-distance, large-section, gently sloping inclined shafts in complex environments, comprising a main structure and a running track, wherein the main structure includes a bucket box, a lifting ring is fixedly connected to one side of the bucket box, and a braking mechanism is provided at the bottom of the bucket box;

[0007] The braking mechanism includes a drive unit located at the bottom of the bucket box, and the drive unit is used to sense gravel on the running track;

[0008] The braking mechanism also includes a locking unit, which is located at the bottom of the bucket box. The locking unit works in conjunction with the drive unit and is used to lock the bucket box onto the running track.

[0009] A discharge mechanism is provided on one side of the hopper, which is used to open one side of the hopper to facilitate discharge.

[0010] Preferably, the drive unit includes a first mounting box, the first mounting box having a mounting cavity inside, a first slider slidably connected inside the mounting cavity, an L-shaped rod fixedly connected inside the first slider, a first spring fixedly connected to one side of the first slider, a first wedge block fixedly connected to one side of the L-shaped rod, a connecting seat fixedly connected to the other side of the L-shaped rod, a sensing block fixedly connected to one side of the connecting seat, a first connecting ring fixedly connected to the outer side of the connecting seat, a second connecting ring rotatably connected to the outer side of the first connecting ring, and a movable wheel fixedly connected to the outer side of the second connecting ring.

[0011] Preferably, the first mounting box is fixedly connected to the bottom of the bucket box, and two first mounting boxes are fixedly connected to the left and right sides of the bottom of the bucket box and are symmetrically distributed front and back.

[0012] Preferably, both sides of the L-shaped rod extend to the outside of the first mounting box. One side of the first mounting box is provided with a moving through groove that matches the moving trajectory of the L-shaped rod. Another side of the first mounting box is provided with a first through hole that matches the L-shaped rod. The other side of the first spring is fixedly connected to the inner wall of the mounting cavity and sleeved on the outside of the L-shaped rod.

[0013] The opening of the movable through slot restricts the moving direction and distance of the L-shaped rod, and thus restricts the moving direction and distance of the movable wheel. Under the action of the first through hole, the L-shaped rod can drive the first wedge block to move freely. Under the action of the elastic force of the first spring, the L-shaped rod, the first wedge block and the movable wheel can be reset.

[0014] Preferably, the connecting seat and the sensing block are fixedly connected by a connecting rod, the length of which is greater than the radius of the moving wheel, and the sensing block is located in front of the moving wheel and inside the running track.

[0015] Since the length of the connecting rod is greater than the radius of the moving wheel, it can ensure that the sensing block is always in front of the moving wheel. The sensing block can collide with the gravel that falls on the running track first. It can not only detect the falling gravel, but also protect the moving wheel from direct collision with the gravel, thus preventing the normal operation of the bucket box.

[0016] Preferably, the second connecting ring has an annular groove inside, the size of which is adapted to the first connecting ring, and the moving wheel is in contact with the inner side of the running track.

[0017] With the cooperation of the first connecting ring and the annular groove, the second connecting ring can rotate outside the connecting seat, which in turn allows the movable wheel fixedly connected to the second connecting ring to rotate, making it easier to drive the bucket box to move along the running track.

[0018] Preferably, the locking unit includes a second mounting box, a second slider is slidably connected inside the second mounting box, a straight rod is fixedly connected inside the second slider, a second wedge block is fixedly connected to one side of the straight rod, a second spring is fixedly connected to one side of the second slider, a locking block is fixedly connected to the other side of the straight rod, and an anti-slip pad is fixedly connected to one side of the locking block.

[0019] Preferably, the second mounting box is fixedly connected to one side of the first mounting box. A second through hole adapted to the L-shaped rod is provided on one side of the second mounting box. The L-shaped rod extends into the second mounting box through the second through hole. The inclined surface of the first wedge block fits against the inclined surface of the second wedge block. The other side of the second spring is fixedly connected to the inner wall of the second mounting box. The other side of the straight rod extends to the outer side of the second mounting box. The locking block is located behind the moving wheel. The anti-slip pad is made of rubber material.

[0020] Under the action of the second perforation, the L-shaped rod can drive the first wedge block to move in the second mounting box. The first wedge block drives the second wedge block to move in position. The rubber anti-slip pad has good elasticity and wear resistance, and also has a high coefficient of friction, which can provide a good anti-slip effect and enhance the braking effect of the locking block on the bucket box.

[0021] Preferably, the unloading mechanism includes a mounting frame, a limit block is slidably connected inside the mounting frame, a mounting base is fixedly connected to one side of the limit block, a rotating shaft is rotatably connected inside the mounting base, an unloading gate is fixedly connected to one side of the rotating shaft, a first magnetic block is fixedly connected to one side of the unloading gate, a second magnetic block is fixedly connected inside the mounting frame, a limit rod is fixedly connected to one side of the mounting frame, and a stop block is rotatably connected to the outer side of the limit rod.

[0022] Preferably, one side of the hopper box is designed to be open, the mounting frame is installed inside the opening of the hopper box, and the inner left and right sides of the mounting frame are provided with limiting grooves that are adapted to the moving trajectory of the limiting block. The inner walls of the left and right sides of the mounting frame are provided with mounting grooves that are adapted to the moving trajectory of the mounting seat. The limiting grooves are connected to the mounting grooves. A handle is fixedly connected to one side of the unloading door, and the stop block is fitted to one side of the unloading door.

[0023] The bucket box is designed with an opening on one side to facilitate the unloading of crushed stone. The movement direction and distance of the unloading gate are guaranteed by the combined restriction of the limiting groove and the installation groove. The installation of the handle facilitates the operation of the unloading gate. When the stop block is attached to one side of the unloading gate, the position of the unloading gate can be fixed to prevent crushed stone from falling from the opening side of the bucket box during material transportation. When the stop block is disengaged from the unloading gate, the fixing effect between the stop block and the unloading gate is released, and the unloading gate can be opened to facilitate the unloading of crushed stone.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this invention, one side of the traction rope is hung on the lifting ring, and the moving wheel is moved on the running track by the traction device, so that the bucket box moves inside the inclined shaft with complex environment and long running distance. When the bucket box is bumped and the crushed stone inside falls onto the running track, the sensing block extended in front of the moving wheel touches the crushed stone first. Under the transmission of the connecting seat, the L-shaped rod drives the moving wheel, the first slider and the first wedge block to move backward, compressing the first spring. Before the moving wheel hits the crushed stone, the sensing block detects the crushed stone first.

[0026] 2. Under the action of the first wedge block, the second wedge block that is in contact with it moves the straight rod and the second slider toward the locking block side. At the same time, the second spring is compressed, causing the locking block to move the anti-slip pad toward the running track side, so that the anti-slip pad is in close contact with the running track. Under the action of the locking block and the anti-slip pad, the bucket box can be locked on the running track, which can prevent the bucket box from sliding rapidly along the running track toward the bottom of the inclined shaft.

[0027] 3. When the bucket box moves to the unloading position along the running track, the present invention first rotates the stop block until it is disengaged from the unloading door, then pulls the handle on one side of the unloading door to make the unloading door rotate outward around the rotating axis and open. Then, the unloading door is pulled up along the limiting groove and the mounting groove until the first magnetic block and the second magnetic block in the mounting frame are magnetically attracted, which can fix the unloading door. The rear of the bucket box is lifted by the curved rail, so that the bucket box tilts forward and the ore is unloaded from the opening on one side of the bucket box. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figure 1-12 The present invention provides a technical solution: a pre-unloading inclined shaft skip for construction of long-distance, large-section, gentle-slope inclined shafts in complex environments, including a main structure 1 and a running track 4. The main structure 1 includes a bucket box 11, a lifting ring 12 is fixedly connected to one side of the bucket box 11, and a braking mechanism 2 is provided at the bottom of the bucket box 11.

[0044] The braking mechanism 2 includes a drive unit 21, which is located at the bottom of the bucket box 11. The drive unit 21 is used to sense the gravel on the running track 4.

[0045] As a further definition of the braking mechanism 2 of the present invention, the drive unit 21 includes a first mounting box 2101. The first mounting box 2101 has a mounting cavity 2102 inside. A first slider 2103 is slidably connected inside the mounting cavity 2102. An L-shaped rod 2104 is fixedly connected inside the first slider 2103. A first spring 2105 is fixedly connected to one side of the first slider 2103. A first wedge block 2106 is fixedly connected to one side of the L-shaped rod 2104. A connecting seat 2107 is fixedly connected to the other side of the L-shaped rod 2104. A sensing block 2108 is fixedly connected to one side of the connecting seat 2107. A first connecting ring 2109 is fixedly connected to the outside of the connecting seat 2107. A second connecting ring 2110 is rotatably connected to the outside of the first connecting ring 2109. A moving wheel 2111 is fixedly connected to the outside of the second connecting ring 2110. The first mounting box 2101 is fixedly connected to the bottom of the bucket box 11. The bottom of the bucket box 11 is located on the left and right sides. Two first mounting boxes 2101 are fixedly connected to both sides and are symmetrically distributed front and back. Both sides of the L-shaped rod 2104 extend to the outside of the first mounting box 2101. One side of the first mounting box 2101 is provided with a moving through groove that matches the moving trajectory of the L-shaped rod 2104. One side of the first mounting box 2101 is provided with a first through hole that matches the L-shaped rod 2104. The other side of the first spring 2105 is fixedly connected to the inner wall of the mounting cavity 2102 and sleeved on the outside of the L-shaped rod 2104. The connecting seat 2107 and the sensing block 2108 are fixedly connected by a connecting rod. The length of the connecting rod is greater than the radius of the moving wheel 2111. The sensing block 2108 is located in front of the moving wheel 2111 and inside the running track 4. The inside of the second connecting ring 2110 is provided with an annular groove 2112. The size of the annular groove 2112 matches the first connecting ring 2109. The moving wheel 2111 fits against the inside of the running track 4.

[0046] The specific implementation method of this embodiment is as follows: First, one side of the traction rope is hung on the lifting ring 12, and the other side of the traction rope is connected to the traction device. The traction device is used to pull the bucket box 11. When the bucket box 11 moves along the running track 4 in the complex environment and long running distance of the inclined shaft, if the bucket box 11 is bumped and causes the gravel to fall and get stuck in the running track 4, the sensing block 2108 located in front of the moving wheel 2111 will collide with the gravel first. Under the transmission of the connecting rod, the connecting seat 2107 drives the L-shaped rod 2104 to move backward, and the moving wheel 2111 moves backward accordingly. This can avoid the moving wheel 2111 colliding with the gravel and causing damage. Under the drive of the L-shaped rod 2104, the first slider 2103 moves backward, which compresses the first spring 2105. At the same time, the first wedge block 2106 also moves backward. With the cooperation between the above structures, the falling gravel can be sensed and a corresponding reaction can be made.

[0047] Example 2

[0048] Please see Figure 1-12 This invention provides a technical solution: a pre-unloading inclined shaft skip for construction of long-distance, large-section, gently sloping inclined shafts in complex environments. This invention makes corresponding improvements to the technical problems mentioned in the background art.

[0049] As a further limitation of the braking mechanism 2 of the present invention, the braking mechanism 2 also includes a locking unit 22, which is disposed at the bottom of the bucket box 11. The locking unit 22 is used in conjunction with the drive unit 21 to lock the bucket box 11 onto the running track 4. The locking unit 22 includes a second mounting box 2201, a second slider 2202 is slidably connected inside the second mounting box 2201, a straight rod 2203 is fixedly connected inside the second slider 2202, a second wedge block 2204 is fixedly connected to one side of the straight rod 2203, a second spring 2205 is fixedly connected to one side of the second slider 2202, and a locking block 2206 is fixedly connected to the other side of the straight rod 2203. One side of the locking block 2206 is fixedly connected to an anti-slip pad 2207. The second mounting box 2201 is fixedly connected to one side of the first mounting box 2101. A second through hole adapted to the L-shaped rod 2104 is opened on one side of the second mounting box 2201. The L-shaped rod 2104 extends into the second mounting box 2201 through the second through hole. The inclined surface of the first wedge block 2106 fits against the inclined surface of the second wedge block 2204. The other side of the second spring 2205 is fixedly connected to the inner wall of the second mounting box 2201. The other side of the straight rod 2203 extends to the outside of the second mounting box 2201. The locking block 2206 is located behind the moving wheel 2111. The anti-slip pad 2207 is made of rubber material.

[0050] The specific implementation of this embodiment is as follows: Under the action of the rearward-moving first wedge block 2106, the second wedge block 2204 that is in contact with it moves towards the running track 4. Driven by the straight rod 2203, the second slider 2202 compresses the second spring 2205. At the same time, the locking block 2206 and the anti-slip pad 2207 both move to be in close contact with the running track 4, which can brake the bucket box 11 on the running track 4 and prevent the bucket box 11 from sliding rapidly along the running track 4 towards the bottom of the inclined shaft, thus preventing a safety accident. After the workers clear the gravel from the running track 4... When the squeezing force received by the sensing block 2108 disappears, under the elastic force of the first spring 2105, the first slider 2103 drives the L-shaped rod 2104, the first wedge block 2106 and the moving wheel 2111 to reset. At the same time, under the elastic force of the second spring 2205, the straight rod 2203 drives the second slider 2202, the second wedge block 2204, the locking block 2206 and the anti-slip pad 2207 to reset, releasing the braking effect of the locking block 2206 on the bucket box 11. Then, the moving wheel 2111 can drive the bucket box 11 to continue moving along the running track 4 to transport the crushed stone out of the inclined shaft.

[0051] Example 3

[0052] Please see Figure 1-12 This invention provides a technical solution: a pre-unloading inclined shaft skip for construction of long-distance, large-section, gently sloping inclined shafts in complex environments. This invention makes corresponding improvements to the technical problems mentioned in the background art.

[0053] As a further limitation of the present invention, a discharge mechanism 3 is provided on one side of the hopper 11. The discharge mechanism 3 is used to open one side of the hopper 11 to facilitate discharge. The discharge mechanism 3 includes a mounting frame 301. A limit block 302 is slidably connected inside the mounting frame 301. A mounting base 303 is fixedly connected to one side of the limit block 302. A rotating shaft 304 is rotatably connected inside the mounting base 303. A discharge gate 305 is fixedly connected to one side of the rotating shaft 304. A first magnetic block 306 is fixedly connected to one side of the discharge gate 305. A second magnetic block 306 is fixedly connected inside the mounting frame 301. 07. A limiting rod 308 is fixedly connected to one side of the mounting frame 301. A stop block 309 is rotatably connected to the outer side of the limiting rod 308. One side of the hopper box 11 is designed to be open. The mounting frame 301 is installed in the opening of the hopper box 11. Limiting grooves that are adapted to the moving trajectory of the limiting block 302 are opened on both the left and right sides of the interior of the mounting frame 301. Mounting grooves that are adapted to the moving trajectory of the mounting seat 303 are opened on both the left and right inner walls of the mounting frame 301. The limiting grooves are connected to the mounting grooves. A handle is fixedly connected to one side of the unloading door 305. The stop block 309 fits against one side of the unloading door 305.

[0054] The specific implementation method of this embodiment is as follows: When the bucket box 11 moves to the unloading position along the running track 4, firstly, the stop block 309 is rotated until it is disengaged from the unloading gate 305. After the positioning effect of the stop block 309 on the unloading gate 305 is released, the handle on one side of the unloading gate 305 is pulled, so that the unloading gate 305 rotates outward around the rotating shaft 304 and opens. Then, the unloading gate 305 is pulled up along the limiting groove and the mounting groove until the first magnetic block 306 is magnetically attracted to the second magnetic block 307 in the mounting frame 301, which can fix the unloading gate 305. Finally, the rear of the bucket box 11 is lifted by the curved track, so that the bucket box 11 tilts forward and the ore is unloaded from the opening on one side of the bucket box 11. By moving the fixed position of the unloading gate 305 to the inside and above of the mounting frame 301, the crushed stone can be unloaded while preventing the crushed stone from getting stuck on the unloading gate 305.
