Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a tunnel floor heave cleaning device. Background Technology

[0002] In underground coal mine tunnels, under the influence of ground pressure, the tunnel floor can irregularly bulge in certain areas. This can cause the steel rails laid on the tunnel floor to tilt or become partially suspended, creating safety hazards such as tilting and bumping for mine cars traveling on the rails. Therefore, it is necessary to restore the tunnel floor to its original position, temporarily halting transportation operations and assigning personnel to remove the bulging sections of the tunnel floor.

[0003] However, clearing the bulging sections of the roadway floor is quite difficult and physically demanding for the operators. This is because the bulging sections are located at the bottom of the rails and sleepers. The workers need to bend over and dig out the coal seam at the bottom of the rails and sleepers with a hoe before they can lower the rails and sleepers to their original positions. Because the coal seam is hard, bending over and digging is not suitable for exerting force, which results in a high level of physical exertion for the operators and low efficiency in repairing the roadway floor. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention provide a roadway floor bulging cleaning device, which facilitates operators in cleaning up the bulging parts of the roadway floor.

[0006] The tunnel floor heave cleaning device of this invention includes: a vehicle body, a cleaning assembly, and a drive assembly. The cleaning assembly includes a connecting seat and a support rod. The connecting seat is rotatably connected to the vehicle body. The rotation axis of the connecting seat is vertically oriented. The connecting seat has a first mounting hole. The central axis of the first mounting hole is perpendicular to and intersects the rotation axis of the connecting seat. The support rod passes through the first mounting hole and is slidable along the axial direction of the first mounting hole. One end of the support rod has a cutting element, and the other end of the support rod has a second mounting hole. The central axis of the second mounting hole is parallel to the rotation axis of the connecting seat. The drive assembly includes a drive member and an eccentric sleeve. The drive member is connected to the vehicle body and has a drive shaft. The eccentric sleeve is fitted onto the drive shaft. At least a portion of the eccentric sleeve is located within the second mounting hole and is rotatably connected to the support rod, so that the drive member drives the support rod to reciprocate around the rotation axis of the connecting seat and to reciprocate along the axial direction of the first mounting hole.

[0007] The roadway floor bulging cleaning device of this invention uses the rotation of the drive shaft of the drive component to drive the eccentric sleeve to rotate, thereby driving the support rod to swing back and forth and slide back and forth, so that the cutting component cuts the coal seam at the bottom of the rails and sleepers to remove the bulging part of the roadway floor and improve the repair efficiency of the roadway floor.

[0008] In some embodiments, the extension of the central axis of the first mounting hole intersects the extension of the central axis of the second mounting hole.

[0009] In some embodiments, the eccentricity of the eccentric sleeve is 0.3mm to 0.7mm, the distance between the cutting element and the connecting seat is a, and the distance between the eccentric sleeve and the connecting seat is b, and the relationship is satisfied: a:b=(5~6):1.

The second connecting plate is detachably connected to the first connecting plate and has a second through hole corresponding to the first through hole. The driving member is detachably connected to the second connecting plate and / or the first connecting plate. The driving shaft passes through the second through hole and the first through hole in sequence, so that the driving shaft is located between the first vertical plate and the second vertical plate. The U-shaped connecting plate is detachably connected to the second connecting plate. The U-shaped connecting plate and the second connecting plate together define a receiving cavity. The connecting seat is rotatably disposed in the receiving cavity. The support rod passes through the receiving cavity, so that one end of the support rod having the second mounting hole is located between the first vertical plate and the second vertical plate.

[0012] In some embodiments, the connecting seat includes a first seat portion and a second seat portion that are detachably connected. The first seat portion is provided with a first arc-shaped groove, and the second seat portion is provided with a second arc-shaped groove corresponding to the first arc-shaped groove. The first arc-shaped groove and the second arc-shaped groove together form the first mounting hole. The first seat portion is rotatably connected to the U-shaped connecting plate, and the second seat portion is rotatably connected to the second connecting plate.

[0013] In some embodiments, the support rod includes a first horizontal segment, a bent segment, and a second horizontal segment connected in sequence.

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The tunnel floor cleaning device of the present invention is described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the tunnel floor cleaning device of this embodiment includes: a vehicle body 1, a cleaning component 2, and a drive component 3.

[0027] like Figures 1 to 3 As shown, the cleaning assembly 2 includes a connecting seat 21 and a support rod 22. The connecting seat 21 is rotatably connected to the vehicle body 1, and the axis of rotation of the connecting seat 21 is along the vertical direction (e.g., Figure 1 The connecting seat 21 is provided with a first mounting hole 201, the central axis of which is perpendicular to and intersects the rotation axis of the connecting seat 21. A support rod 22 passes through the first mounting hole 201 in the front-to-back direction and is slidable along the axial direction of the first mounting hole 201. One end of the support rod 22 (e.g., in the vertical direction) is set. Figure 1 The front end of the middle support rod 22 has a cut-out piece 23, and the other end of the support rod 22 (such as...) Figure 1 The rear end of the middle support rod 22 is provided with a second mounting hole 202. The central axis of the second mounting hole 202 is parallel to the rotation axis of the connecting seat 21, that is, the second mounting hole 202 extends in the vertical direction.

[0028] The drive assembly 3 includes a drive member 31 (explosion-proof motor) and an eccentric sleeve 32. The drive member 31 is connected to the vehicle body 1. The drive member 31 has a drive shaft 311, which is arranged in the vertical direction. The eccentric sleeve 32 is fitted on the drive shaft 311. At least a portion of the eccentric sleeve 32 is located in the second mounting hole 202 and is rotatably connected to the support rod 22, so that the drive member 31 can drive the support rod 22 to swing back and forth about the rotation axis of the connecting seat 21 and slide back and forth along the axial direction of the first mounting hole 201.

[0029] It is understandable that the inner and outer circles of the eccentric sleeve 32 are eccentric, the central axis of the inner circle of the eccentric sleeve 32 is coaxial with the central axis of the drive shaft 311 of the drive member 31, and the central axis of the outer circle of the eccentric sleeve 32 is coaxial with the central axis of the second mounting hole 202.

[0030] When the drive unit 31 is activated, the drive shaft 311 of the drive unit 31 rotates, which in turn drives the eccentric sleeve 32 to rotate, thus forming a cam-type operating state. The eccentric sleeve 32 drives the support rod 22 to reciprocate around the connecting seat 21 as the rotation center, and also drives the support rod 22 to slide back and forth along the extension direction of the first mounting hole 201, thereby driving the cutting part 23 to move.

[0031] Therefore, the roadway floor bulging cleaning device of this embodiment of the invention drives the support rod 22 to swing back and forth and slide back and forth by rotating the drive shaft 311 of the drive member 31 and driving the eccentric sleeve 32 to rotate, thereby enabling the cutting member 23 to cut the coal seam at the bottom of the rail and sleeper, so as to remove the part of the roadway floor that has bulged, reduce the labor intensity of the operators, and improve the repair efficiency of the roadway floor.

[0032] In some embodiments, such as Figures 1 to 3 As shown, the extension line of the central axis of the first mounting hole 201 intersects the extension line of the central axis of the second mounting hole 202.

[0033] It is understood that the central axis of the first mounting hole 201 is perpendicular to and intersects the rotation axis of the connecting seat 21, and the central axis of the second mounting hole 202 is parallel to the rotation axis of the connecting seat 21. The extension of the central axis of the first mounting hole 201 intersects the extension of the central axis of the second mounting hole 202. Therefore, the extension of the central axis of the first mounting hole 201 is perpendicular to and intersects the extension of the central axis of the second mounting hole 202. In other words, the central axes of the first mounting hole 201, the second mounting hole 202, and the rotation axis of the connecting seat 21 are all located in the same plane.

[0034] In some embodiments, the eccentricity of the eccentric sleeve 32 is 0.3mm to 0.7mm, the distance between the cutting part 23 and the connecting seat 21 is a, and the distance between the eccentric sleeve 32 and the connecting seat 21 is b, and the relationship is satisfied: a:b=(5~6):1.

[0035] Optionally, the eccentricity of the eccentric sleeve 32 is 0.3mm, 0.4mm, 0.5mm, 0.6mm, or 0.7mm, and the distance between the cutting piece 23 and the connecting seat 21 is 5 times, 5.5 times, or 6 times the distance between the eccentric sleeve 32 and the connecting seat 21. Thus, the support rod 22 drives the cutting piece 23 to reciprocate slightly, with a small swing amplitude occupying little space, resulting in a low probability of injury to surrounding equipment and operators, and minimal safety hazards.

[0036] In some embodiments, such as Figures 1 to 3 As shown, the vehicle body 1 includes an axle 11, a support frame 12 and a handle 13 mounted on the axle 11. The two ends of the axle 11 are respectively equipped with wheels 14, and the connecting seat 21 is rotatably connected to the support frame 12.

[0037] Optionally, such as Figures 1 to 3 As shown, the handlebars are U-shaped, and the front end of the handlebars is welded to the outer peripheral wall of the axle 11 so that the operator can push the roadway floor cleaning device of this embodiment of the invention to move.

[0038] In some embodiments, such as Figures 1 to 3As shown, the support frame 12 includes a first vertical plate 121, a second vertical plate 122, a first connecting plate 123, a second connecting plate 124, and a U-shaped connecting plate 125.

[0039] The first vertical plate 121 and the second vertical plate 122 are along the length direction of the axle 11 (e.g.) Figure 1 The vertical plates 121 and 122 are spaced apart on the axle 11 in a left-right direction. The first vertical plate 121 is located to the right of the second vertical plate 122. The lower ends of both the first vertical plate 121 and the second vertical plate 122 are provided with grooves that match the outer surface of the axle 11, so that the first vertical plate 121 and the second vertical plate 122 can be connected to the outer surface of the axle 11 by welding. The first connecting plate 123 is horizontally arranged and has a notch on its front side. The lower end face of the first connecting plate 123 is connected to the upper end of the first vertical plate 121 and the second vertical plate 122 by welding. The first connecting plate 123 is provided with a first through hole, which extends in the vertical direction and is connected to the notch.

[0040] The second connecting plate 124 is detachably connected to the first connecting plate 123, and the second connecting plate 124 is provided with a second through hole corresponding vertically to the first through hole. The driving member 31 is detachably connected to the second connecting plate 124 and / or the first connecting plate 123, and the driving shaft 311 passes through the second through hole and the first through hole in sequence, so that the driving shaft 311 is located between the first vertical plate 121 and the second vertical plate 122.

[0041] Specifically, the first connecting plate 123, the second connecting plate 124 and the driving component 31 are each provided with a plurality of corresponding bolt holes, and the three are connected to each other by a plurality of bolts.

[0042] The opening of the U-shaped connecting plate 125 faces upward. The U-shaped connecting plate 125 and the second connecting plate 124 are detachably connected by bolts. The U-shaped connecting plate 125 is located on the front side of the first connecting plate 123. The U-shaped connecting plate 125 and the second connecting plate 124 together define a receiving cavity. The connecting seat 21 is rotatably disposed in the receiving cavity. The support rod 22 passes through the receiving cavity so that one end of the support rod 22 with the second mounting hole 202 is located between the first vertical plate 121 and the second vertical plate 122.

[0043] Therefore, the connection between the drive shaft 311 and the support rod 22 is enclosed by the first vertical plate 121, the second vertical plate 122, the first connecting plate 123, the second connecting plate 124 and the U-shaped connecting plate 125, so as to avoid safety problems caused by direct exposure to the outside world.

[0044] In some embodiments, such as Figures 1 to 3As shown, the connecting seat 21 includes a first seat portion 211 and a second seat portion 212 that are detachably connected, with the first seat portion 211 located below the second seat portion 212. The upper surface of the first seat portion 211 is provided with a first arc-shaped groove, and the lower surface of the second seat portion 212 is provided with a second arc-shaped groove that corresponds vertically to the first arc-shaped groove. The first arc-shaped groove and the second arc-shaped groove together form a first mounting hole 201.

[0045] Optionally, such as Figure 1 As for Figure 3 As shown, the U-shaped connecting plate 125 has a first mounting hole, and the first connecting plate 123 has a second mounting hole. The lower surface of the first seat 211 has a first rotating shaft, which rotatably fits into the first mounting hole, allowing the first seat 211 to be rotatably connected to the U-shaped connecting plate 125. The upper surface of the second seat 212 has a second rotating shaft, which rotatably fits into the second mounting hole, allowing the second seat 212 to be rotatably connected to the second connecting plate 124.

[0046] In some embodiments, such as Figure 1 As for Figure 3 As shown, the support rod 22 includes a first horizontal segment 221, a bent segment 222, and a second horizontal segment 223 connected sequentially from front to back. The vertical height of the first horizontal segment 221 is lower than the vertical height of the second horizontal segment 223. The cut piece 23 is connected to the end of the first horizontal segment 221 away from the bent segment 222 (e.g., Figure 1 The second mounting hole 202 is located at the end of the second horizontal section 223 away from the bent section 222 (e.g., the front end of the middle support rod 22) and is connected to the second horizontal section 223. Figure 1 (The rear end of the middle support rod 22). This is to ensure that the cutting element 23 is as close as possible to the bottom of the coal seam of the rail and sleeper during the cutting process.

[0047] Furthermore, the length of the first horizontal segment 221 is greater than the length of the second horizontal segment 223, so that the cutting element 23 is kept as far away as possible from other components of the roadway floor cleaning device of this embodiment of the invention, so as to avoid affecting the cutting operation.

[0048] In some embodiments, such as Figure 1 As for Figure 3 As shown, a blind hole is provided at the end of the first horizontal segment 221 away from the bending segment 222. The cutting component 23 includes a cutting head 231, a connecting post 232 and a limiting pin 233. The cutting head 231 is connected to the connecting post 232, and the connecting post 232 is inserted into the blind hole. A first limiting hole is provided on the first horizontal segment 221, and a second limiting hole corresponding to the first limiting hole is provided on the connecting post 232. The limiting pin 233 is sequentially fitted into the first limiting hole and the second limiting hole.

[0049] It is understandable that the cutting head 231 is detachably fixed to the support rod 22 by the connecting column 232 and the limiting pin 233, so as to facilitate the maintenance and replacement of the cutting head 231.

[0050] Optionally, such as Figure 1 As for Figure 3 As shown, the front side of the cutting head 231 is a serrated surface, used to cut the coal seam at the bottom of the rails and sleepers.
