[0003] When the existing lifting device for coal mining and transportation is in use, the motor drives the winding drum to rotate, so that the winding drum reels the wire rope, thereby pulling the lifting container up and down under the guidance of the guide rail, thereby completing the lifting and transportation of the coal mine.

[0004] Although the above-mentioned lifting device for coal mining and transportation can better solve the problem of coal transportation and lifting, in the process of lifting coal, due to changes in the geological conditions of the mine, such as the shaft passing through the folded structure, the rock layer may be deformed due to the continuous action of structural stress, which may cause the container track to twist and deform, and local uplift. If it is not discovered in time, when the lifting container passes through the uplifted track each time, the container guide wheel will generate instantaneous impact force when contacting the uplifted part, causing the container to jump up and down, affecting the stability of the lifting device during use, and even causing the lifting container to deviate from the track and hit the well wall or shaft facilities during the transportation of coal, causing secondary accidents and reducing the safety of the lifting device during use.

[0005] Therefore, the present invention proposes a lifting device for tunnel mining and transportation to solve the above problems. Summary of the Invention

[0011] Preferably, the detection mechanism further includes a connecting shaft, which is fixedly connected between the two detection wheels, and both ends of the connecting shaft respectively pass through the rotating rod and are rotatably connected to the rotating rod.

[0012] Preferably, a magnetic block is fixedly connected to one side of the detection rod, and an arc-shaped magnetic sheet is fixedly connected to the side of the U-shaped mounting plate close to the detection rod. The magnetic block and the arc-shaped magnetic sheet are arranged to attract each other and the magnetic block is in contact with the arc-shaped magnetic sheet.

[0013] Preferably, a torsion spring is sleeved on the shaft end of the rotating rod, and both ends of the torsion spring are fixedly connected to the fixed block and the rotating rod respectively.

[0014] Preferably, the U-shaped mounting plate is also provided with a limiting mechanism for assisting in guiding the lifting container, and the limiting mechanism includes two support arms, both of which are fixedly connected to the bottom of the U-shaped mounting plate, and one end of each support arm is slidably connected to a sliding arm, and one end of the sliding arm is fixedly connected to a support column.

[0034] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described in some examples may be combined in other examples.

[0035] like Figure 1 - Figure 7 As shown, this embodiment provides a lifting device for tunnel mining and transportation, including a lifting guide rail 1, a lifting container 11 is provided on the upper surface of the lifting guide rail 1, and a detection mechanism is provided on one side of the lifting container 11. The detection mechanism is used to detect the flatness of the lifting guide rail 1, and the detection mechanism includes a U-shaped mounting plate 201, and the U-shaped mounting plate 201 is fixedly connected to the bottom of the lifting container 11. Two fixed blocks 202 are fixedly connected to the bottom of the U-shaped mounting plate 201, and the two fixed blocks 202 are rotatably connected to a rotating rod 203 on the opposite sides. One side of the rotating rod 203 is rotatably connected to a detection wheel 204, and both sides of the U-shaped mounting plate 201 are slidably connected to a push rod 205, and the side of the U-shaped mounting plate 201 close to the push rod 205 is rotatably connected to a detection rod 206. When the rotating rod 203 rotates a set angle, it can push the push rod 205 to slide, and the push rod 205 can drive the detection rod 206 to rotate by sliding.

[0036] A plurality of container guide wheels 12 are fixedly connected to the bottom of the lifting container 11 , and each container guide wheel 12 is in contact with the lifting guide rail 1 . A pulling rope 13 is fixedly connected to one side of the lifting container 11 .

[0037] The lifting rope 13 is connected to an external receiving drum at one end away from the lifting container 11, and the winding drum is driven to rotate by an external driving source. The external driving source can be implemented as a driving motor, which can drive the lifting rope 13 to lift the lifting container 11, and the lifting guide rail 1 is set on the inclined mine ground.

[0038] The detection mechanism also includes a connecting shaft 207, which is fixedly connected between the two detection wheels 204. Both ends of the connecting shaft 207 respectively pass through the rotating rod 203 and are rotatably connected to the rotating rod 203. A magnetic block 208 is fixedly connected to one side of the detection rod 206, and an arc-shaped magnetic piece 209 is fixedly connected to the side of the U-shaped mounting plate 201 close to the detection rod 206. The magnetic poles of the magnetic block 208 and the arc-shaped magnetic piece 209 are attracted to each other, and the magnetic block 208 is in contact with the arc-shaped magnetic piece 209. A torsion spring 210 is provided on the shaft end of the rotating rod 203, and the two ends of the torsion spring 210 are respectively fixedly connected to the fixed block 202 and the rotating rod 203.

[0039] By setting the connecting shaft 207, when a bulge appears on one side of the lifting guide rail 1, it can simultaneously drive the symmetrically arranged detection wheels 204 to jump up at the same time, and then the symmetrically arranged support arms 301 and sliding arms 302 on the subsequent limiting mechanism are simultaneously unfolded, thereby maintaining the stability of the lifting device during use.

[0040] In the prior art, if the lifting guide rail 1 is twisted and deformed and is not discovered in time, the stability and safety of the lifting device during use will be reduced. Compared with the prior art, with the implementation of this embodiment, the staff can observe the status of the detection rod 206 to promptly discover the problem of bulging of the lifting guide rail 1, so that the lifting guide rail 1 can be repaired in time, which greatly improves the safety of the lifting device during use. From an environmental protection perspective, the thrust of the raised part is used to trigger the detection mechanism, which saves electricity, reduces detection costs, and meets the safety monitoring needs of mine operations.

[0041] Further examples:

[0042] The U-shaped mounting plate 201 is also provided with a limiting mechanism for assisting in guiding the lifting container 11. The limiting mechanism includes two support arms 301, and the two support arms 301 are fixedly connected to the bottom of the U-shaped mounting plate 201. One end of each support arm 301 is slidably connected to a sliding arm 302, and one end of the sliding arm 302 is fixedly connected to a support column 303. The outer surface of the support column 303 is rotatably connected to a rotating sleeve 304, and one end of the support column 303 is rotatably connected to a ball bearing 305. One side of the detection rod 206 is fixedly connected to a pressure rod 306, and the bottom of the pressure rod 306 contacts the adjacent rotating sleeve 304. When the pressure rod 306 rotates, it can drive the rotating sleeve 304 to rotate. Two limit blocks 308 are fixedly connected to one side of the U-shaped mounting plate 201, and each sliding arm 302 is fixedly connected to one side of a clamping column 307, which is clamped with the adjacent limit block 308.

[0043] Everything in the above examples works as follows:

[0044] Initial state: the detection wheel 204 is in contact with the lifting guide rail 1, the torsion spring 210 is in a normal state, the rotating rod 203 is at an appropriate distance from the bottom of the push rod 205, the detection rod 206 is in a horizontal state, the magnetic block 208 is attracted to the arc-shaped magnetic piece 209, and the support arm 301 and the sliding arm 302 are parallel to the U-shaped mounting plate 201. Figure 5 As shown, at this time, the sliding arm 302 does not slide, and the clamping column 307 is clamped with the limiting block 308.

[0045] The following is the working principle of the testing mechanism and its beneficial effects:

[0046] During normal operation, the contact between the detection wheel 204 and the lifting container 11 can provide auxiliary support for the lifting and conveying work of the lifting container 11, thereby improving the stability of the lifting device during normal operation. When the raised part on the lifting guide rail 1 does not reach the warning value, the detection wheel 204 will produce a slight jump and drive the rotating rod 203 to swing slightly, but at this time the rotating rod 203 is not in contact with the push rod 205.

[0047] Furthermore, when the bulge at a certain point of the lifting guide rail 1 reaches the warning value, the lifting container 11 gradually approaches the bulge position under the guidance of the lifting guide rail 1 and the container guide wheel 12 during the lifting process. The detection wheel 204 will first contact the bulge. When in contact, the bulge will squeeze the detection wheel 204, causing the detection wheel 204 to jump to a greater height, thereby driving the rotating rod 203 to swing to a greater angle. The rotating rod 203 contacts the bottom of the push rod 205 and squeezes and pushes the push rod 205 to slide upward, thereby causing the detection wheel 204 to jump to a greater height. The push rod 205 pushes the detection rod 206 to rotate in the direction away from the push rod 205. During rotation, due to the setting of the magnetic block 208 and the arc-shaped magnetic piece 209, the detection rod 206 drives the magnetic block 208 to move in an arc trajectory, so that the magnetic block 208 and the arc-shaped magnetic piece 209 are always in an attractive state. After the detection wheel 204 passes through and moves away from the raised position, driven by the rebound of the torsion spring 210, when the rotating rod 203, the detection wheel 204 and the push rod 205 are reset, the detection rod 206 is still in a lifted state.

[0048] Through the setting of the detection mechanism, during the lifting operation of the lifting container 11, if the lifting guide rail 1 bulges, the thrust generated by the raised part on the detection wheel 204 can drive the detection rod 206 to rotate a certain angle. From a safety perspective, through the cooperation of the rotating rod 203, the detection wheel 204, the push rod 205 and the detection rod 206, the staff can timely discover the problem of bulging of the lifting guide rail 1 by observing the state of the detection rod 206, so that the lifting guide rail 1 can be repaired in time, which greatly improves the safety of the lifting device during use. From an environmental protection perspective, the thrust of the raised part is used to trigger the detection mechanism, which saves electricity, reduces detection costs, and meets the safety monitoring needs of mine operations.

[0049] In addition, when the uplift angle is large, the swing angle of the detection wheel 204 and the rotating rod 203 will increase, thereby causing the push rod 205 to push the detection rod 206 to increase its rotation angle. Through the rotation of the detection rod 206 and the coordinated setting of the magnetic block 208 and the arc-shaped magnetic piece 209, the staff can observe the rotation angle of the detection rod 206 to judge the uplift angle, so that the staff can make different judgments in time when facing different uplift situations, further improving the safety of the lifting device when in use.

[0050] The following is the working principle of the limit mechanism and its beneficial effects:

[0051] When the cam 308 is lifted up, the cam 308 will be released, and the cam 308 will be in a state of being lifted.

[0052] Furthermore, by setting up the detection mechanism and the limiting mechanism, with their cooperation, when the lifting device is performing the lifting work, after the detection mechanism detects the bulge, before the staff finds it, the limiting mechanism can timely ensure the safety of the transportation work. At the same time, through the limitation and rotation of the rotating sleeve 304 and the ball 305, not only can the lifting container 11 be effectively prevented from falling off the track due to jumping, but the stability of the transportation and lifting work can also be further guaranteed.

[0053] Furthermore, after the staff inspects the raised part of the lifting guide rail 1, they can manually push the detection rod 206 to reset it. At the same time, through the rotation and sliding of the sliding arm 302, the clamping column 307 and the limit block 308 are re-engaged, thereby completing the limit reset of the detection mechanism and the limit mechanism, thereby facilitating the next detection and protection work.

[0054] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
