Description

Technical Field

[0001] This invention relates to the field of building fence technology, and in particular to a mining material transport gantry with a scanning detection structure. Background Technology

[0002] The mining material transport gantry crane is a special lifting equipment designed specifically for mining environments. Constructed with a high-strength steel portal frame, it integrates material transport functions with a scanning and detection system. Its core structure includes a main beam, columns, a traveling mechanism, and scanning components. Driven by an electric or hydraulic system, it lifts and moves the lifting device horizontally, enabling the safe transfer of heavy objects such as ore and equipment. The scanning and detection module can be equipped with laser scanners and sensors to monitor material morphology, weight distribution, and environmental parameters in real time, assisting in precise operations and providing safety warnings, meeting the needs of complex working conditions in mines such as heavy loads, high dust levels, and confined spaces.

[0003] However, when existing transport gantry cranes are in use, due to the complex mining environment, ore fragments, dust and other debris easily accumulate in the travel tracks or limit slots. During operation, when the travel wheels move in the limit slots full of debris, they will encounter greater resistance, resulting in uneven movement and jamming. This not only affects the normal operating efficiency of the equipment and increases energy consumption, but also causes uneven stress on various parts of the equipment, accelerates wear, shortens the service life of the equipment, and may even cause equipment failure due to jamming, resulting in production interruption and causing many inconveniences and economic losses to mining operations.

[0004] In view of this, a gantry crane for transporting mining materials with a scanning detection structure is proposed. Summary of the Invention

[0005] To overcome the technical defects of existing technologies, this invention provides a mining material transport gantry with a scanning detection structure, which has the technical characteristics of synchronous rotation to clear debris, avoid jamming, and ensure smooth and stable operation.

[0006] The technical solution adopted in this invention is: a mining material transport gantry with a scanning detection structure, comprising a support leg, a crossbeam, a self-cleaning walking drive assembly, a connecting top plate, a vertical cylinder, a U-shaped suspension frame, an extended clamping assembly, a pin positioning assembly, and a pushing and squeezing assembly. The crossbeam is fixed to the top of the support leg. The self-cleaning walking drive assembly is installed in a walking limit groove opened on the crossbeam. The connecting top plate is fixed to the top of the self-cleaning walking drive assembly and is located above the crossbeam. The vertical cylinder is fixedly inserted into both ends of the connecting top plate. The U-shaped suspension frame is fixed to the telescopic end of the vertical cylinder. The extended clamping assembly and the pushing and squeezing assembly are both installed on the inner wall of the U-shaped suspension frame, and the extended clamping assembly is located above the pushing and squeezing assembly for controlling the pushing and squeezing assembly. The pin positioning assembly is inserted into the side wall of the U-shaped suspension frame for fixing the extended clamping assembly to the U-shaped suspension frame.

[0007] To enable the walking wheel to rotate in the walking limit groove by controlling the drive motor to start, thus achieving movement, and simultaneously enabling the cleaning roller to rotate via the linkage rotating shaft through the transmission belt, thus achieving synchronous cleaning of the walking limit groove and avoiding jamming, the present invention improves upon this invention by including an L-shaped mounting base, a walking wheel, a rotation drive shaft, a drive motor, an extension protrusion, a cleaning roller, the linkage rotating shaft, and the transmission belt. The walking wheel is rotatably mounted on the inner wall of the L-shaped mounting base via the rotation drive shaft and is rotatably engaged in the walking limit groove on one side. The drive motor is fixed on the outer wall of the L-shaped mounting base, and one end of the rotation drive shaft is fixedly connected to the output shaft of the drive motor. The extension protrusion is fixed on the side wall of the L-shaped mounting base. The cleaning roller is rotatably mounted on the inner wall of the extension protrusion via the linkage rotating shaft and is located in the walking limit groove on one side. The linkage rotating shaft is connected to the rotation drive shaft via the transmission belt. A scanning camera is embedded at the bottom of the extension protrusion.

[0008] To improve stability during movement via the limiting slider, the present invention further includes a first synchronous wheel, a second synchronous wheel, a vertical side plate, and a limiting slider. The first synchronous wheel is fixedly sleeved on the rotary drive shaft, and the second synchronous wheel is fixedly sleeved on the linkage rotary shaft. The first and second synchronous wheels are connected by a transmission belt. The vertical side plate is fixed to one end of the L-shaped mounting base, and the limiting slider is fixed to the inner wall of the vertical side plate. The limiting slider is slidably engaged in the walking limiting groove on the other side.

[0009] To enable the clamping part to move inside the U-shaped suspension frame via the limiting slide rod and the square positioning strip, thereby allowing the clamping part and the protruding support part to clamp materials of different sizes, the present invention improves upon this invention by including the extending clamping assembly as follows: the limiting slide rod, the square positioning strip, the rotating connecting seat, the clamping part, the protruding support part, and the rotating contact roller. The limiting slide rod and the square positioning strip are slidably inserted into the side wall of the U-shaped suspension frame. The rotating connecting seat is fixed to one end of the limiting slide rod and the square positioning strip. The clamping part is rotatably mounted on the rotating connecting seat, and there are two clamping parts symmetrically distributed. A rubber protrusion is provided on the inner wall of the bottom end of the clamping part. The top end of the clamping part is connected to the pushing and squeezing assembly. The protruding support part is fixed on the inner wall of the bottom end of the clamping part. An installation groove is provided at the bottom corner of the protruding support part. The rotating contact roller is rotatably mounted on the inner wall of the installation groove. The square positioning strip is fixedly connected to the U-shaped suspension frame via the pin positioning assembly.

[0010] In order to push the L-shaped positioning plate by means of the positioning spring, so that the tops of the two clamping parts on both sides converge inward, and the two clamping parts contact the material in a V-shape, the present invention is improved in that the extended clamping assembly further includes the L-shaped positioning plate, the hinge shaft, the positioning slide rod and the positioning spring. The L-shaped positioning plate is rotatably connected to the top outer wall of the clamping part through the hinge shaft. The positioning slide rod is slidably inserted into both ends of the U-shaped suspension frame. The L-shaped positioning plate is fixedly connected to one end of the positioning slide rod, and the L-shaped positioning plate is elastically connected to the inner wall of the U-shaped suspension frame through the positioning spring.

[0011] In order to fix the square positioning strip to the U-shaped suspension frame by means of the positioning pin, the present invention is improved in that the pin positioning assembly includes the positioning pin, the magnetic plate and the handle. The positioning pin is inserted into the positioning pin holes corresponding to those opened on the U-shaped suspension frame and the square positioning strip. The magnetic plate is fixed to one end of the positioning pin and is magnetically connected to the U-shaped suspension frame. The handle is fixed to the outer wall of the magnetic plate.

[0012] In order to control the rotation of the bidirectional threaded rod so that the two pushing threaded blocks drive the first L-shaped push plate and the second L-shaped push plate to move outward synchronously, thereby moving the tops of the two clamping parts in a figure-eight shape to both sides, the present invention improves upon this invention by including the bidirectional threaded rod, the pushing threaded blocks, the first L-shaped push plate, and the second L-shaped push plate in the pushing and pressing assembly. The bidirectional threaded rod is rotatably mounted on the inner wall of the U-shaped suspension frame. The pushing threaded blocks are threadedly sleeved on the bidirectional threaded rod, and there are two pushing threaded blocks. The two pushing threaded blocks are respectively located at the reverse thread ends of the bidirectional threaded rod. The first L-shaped push plate and the second L-shaped push plate are respectively fixed to the bottom of the two pushing threaded blocks, and the first L-shaped push plate and the second L-shaped push plate are symmetrically distributed. One end of the first L-shaped push plate and the second L-shaped push plate are respectively located on the inner side of the two clamping parts.

[0013] In order to enable the bidirectional threaded rod to rotate by controlling the servo motor to start, and to limit the push threaded block under the action of the transverse smooth rod, the present invention is improved in that the push extrusion assembly further includes the servo motor and the transverse smooth rod. The servo motor is fixed on the outer wall of the U-shaped suspension frame, one end of the bidirectional threaded rod is fixedly connected to the output shaft of the servo motor, the transverse smooth rod is fixed on the inner wall of the U-shaped suspension frame, and the push threaded block is slidably sleeved on the transverse smooth rod.

[0014] The beneficial effects of this invention are: 1. During operation, when the walking wheel moves within the walking limit groove, the self-cleaning walking drive component drives the cleaning roller to rotate synchronously via the transmission belt, which can promptly clean debris in the groove, effectively avoiding jamming caused by foreign objects and ensuring smooth and stable operation of the component.

[0015] 2. The extendable gripping assembly is flexibly adjustable and can automatically move closer to or away from materials of different sizes and shapes. The rotating contact roller cooperates with the protruding support part, and the rubber protrusion increases friction to prevent materials from slipping, thus improving stability during use.

[0016] 3. The pin positioning component and the pushing and squeezing component ensure stable and accurate clamping while allowing for flexible adjustment of clamping force to stably clamp different materials.

[0017] 4. The scanning camera is fixedly embedded in the self-cleaning walking drive component, which can accurately locate materials during movement and improve transfer efficiency. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-9 As shown, this embodiment provides a mining material transport gantry with a scanning detection structure, such as... Figure 1 and Figure 2As shown, the assembly includes a support leg 1, a crossbeam 2, a self-cleaning walking drive assembly 3, a connecting top plate 4, a vertical cylinder 5, a U-shaped suspension frame 6, an extended clamping assembly 7, a pin positioning assembly 8, and a pushing and squeezing assembly 9. The crossbeam 2 is fixed to the top of the support leg 1. The self-cleaning walking drive assembly 3 is installed in a walking limit groove on the crossbeam 2. The connecting top plate 4 is fixed to the top of the self-cleaning walking drive assembly 3. The self-cleaning walking drive assembly 3 is installed in the walking limit groove of the crossbeam 2 and can move flexibly, driving the top connecting top plate 4 to achieve position adjustment, which facilitates subsequent precise material clamping. Its self-cleaning function can avoid jamming and ensure smooth operation. The connecting top plate 4 is located above the crossbeam 2. Vertical cylinders 5 are fixedly inserted into both ends of the connecting top plate 4. A U-shaped suspension frame 6 is fixed to the telescopic end of the vertical cylinder 5. The extended clamping assembly 7 and the pushing and squeezing assembly 9 are both installed on the inner wall of the U-shaped suspension frame 6. The telescopic movement of the vertical cylinder 5 drives the U-shaped suspension frame to rise and fall, adjusting the height to suit the material. The extended clamping assembly 7, in conjunction with the pushing and squeezing assembly 9, can flexibly and stably clamp different sizes of mining materials. The extended clamping component 7 is located above the pushing and squeezing component 9 and is used to control the pushing and squeezing component 9. The pin positioning component 8 is inserted into the side wall of the U-shaped suspension frame 6 and is used to fix the extended clamping component 7 on the U-shaped suspension frame 6. When clamping materials, the pin positioning component 8 is removed first, so that the extended clamping component 7 moves down. After the extended clamping component 7 has completely clamped the material, the pin positioning component 8 is inserted to limit the extension clamping component 7 and control the pushing and squeezing component 9 to control the extension clamping component 7 so that the extension clamping component 7 clamps the material. Then, the extended clamping component 7 is controlled to rise so as to facilitate the transfer of the material.

[0021] Based on the above description Figure 3The self-cleaning walking drive assembly 3 includes an L-shaped mounting base 301, a walking wheel 302, a rotary drive shaft 303, a drive motor 304, an extension protrusion 305, a cleaning roller 306, a linkage rotary shaft 307, and a transmission belt 308. The walking wheel 302 is rotatably mounted on the inner wall of the L-shaped mounting base 301 via the rotary drive shaft 303. The walking wheel 302 is rotatably engaged in a walking limit groove on one side. The drive motor 304 is fixed on the outer wall of the L-shaped mounting base 301, and one end of the rotary drive shaft 303 is fixedly connected to the output shaft of the drive motor 304. Controlling the drive motor 304 to turn on allows the rotary drive shaft 303 to rotate, causing the walking wheel 302 to rotate in the walking limit groove. The extension protrusion... 305 is fixed on the side wall of L-shaped mounting base 301. The cleaning roller 306 is rotatably mounted on the inner wall of the extension protrusion 305 via the linkage rotating shaft 307. The cleaning roller 306 is located in the travel limiting groove on one side, and the linkage rotating shaft 307 is connected to the rotary drive shaft 303 via the transmission belt 308. When the drive motor 304 drives the rotary drive shaft 303 to rotate, the cleaning roller 306 rotates in the travel limiting groove under the action of the transmission belt 308, realizing automatic cleaning of the travel limiting groove during travel and avoiding jamming problems. A scanning camera is embedded at the bottom of the extension protrusion 305. Under the action of the scanning camera, the position of the material can be accurately judged, improving the material transfer efficiency.

[0022] Based on the above description Figure 4 The self-cleaning walking drive assembly 3 also includes a first synchronous wheel 309, a second synchronous wheel 310, a vertical side plate 311, and a limiting slider 312. The first synchronous wheel 309 is fixedly sleeved on the rotary drive shaft 303, and the second synchronous wheel 310 is fixedly sleeved on the linkage rotary shaft 307. The first synchronous wheel 309 and the second synchronous wheel 310 are connected by a transmission belt 308 to ensure that the walking wheel 302 and the cleaning roller 306 operate synchronously. The vertical side plate 311 is fixed to one end of the L-shaped mounting base 301, and the limiting slider 312 is fixed on the inner wall of the vertical side plate 311. The limiting slider 312 is slidably engaged in the walking limiting groove on the other side. The limiting slider 312 can enhance the movement stability, avoid deviation, and ensure smooth and efficient operation.

[0023] Based on the above description Figure 5 , Figure 6 and Figure 7The extended clamping assembly 7 includes a limiting slide bar 701, a square positioning bar 702, a rotating connecting seat 703, a clamping part 704, a protruding support part 705, and a rotating contact roller 706. The limiting slide bar 701 and the square positioning bar 702 are slidably inserted into the side wall of the U-shaped suspension frame 6. The rotating connecting seat 703 is fixed to one end of the limiting slide bar 701 and the square positioning bar 702. The clamping part 704 is rotatably mounted on the rotating connecting seat 703, and the clamping part 704 is divided into two symmetrically distributed parts. The sliding limiting slide bar 701 and the square positioning bar 702 slide on the U-shaped suspension frame 6, and the clamping part 704 rotates on the rotating connecting seat 703. As the clamping part 704 moves down, the two symmetrically distributed clamping parts 704 can automatically move closer or further away for materials of different sizes and shapes. A rubber protrusion is provided on the inner wall of the bottom end of the gripping part 704. The top end of the gripping part 704 is connected to the pushing and squeezing assembly 9. The protruding support part 705 is fixed on the inner wall of the bottom end of the gripping part 704. An installation groove is provided at the bottom corner of the protruding support part 705. The rotating contact roller 706 is rotatably installed on the inner wall of the installation groove. When gripping the mineral material, the two gripping parts 704 in a figure-eight shape move down, and the rotating contact roller 706 contacts the material. As the gripping parts 704 move down, the rotating contact roller 706 rolls on the material. When the protruding support part 705 moves to the bottom of the material, the pushing and squeezing assembly 9 is controlled to act on the top end of the gripping part 704, so that the tops of the two gripping parts 704 separate and the bottoms of the two gripping parts 704 come closer, so that the protruding support part 705 can support the bottom of the material. The rubber protrusion on the inner wall of the bottom end of the gripping part 704 increases the friction and prevents the material from slipping. The square positioning strip 702 is fixedly connected to the U-shaped suspension bracket 6 via the pin positioning assembly 8, so as to position the square positioning strip 702 and the rotating connecting seat 703, ensuring that the two gripping parts 704 will not move to the sides when the material is clamped. The extendable clamping assembly 7 also includes an L-shaped positioning plate 707, a hinge shaft 708, a positioning slide rod 709, and a positioning spring 710. The L-shaped positioning plate 707 is rotatably connected to the top outer wall of the clamping part 704 via the hinge shaft 708. The positioning slide rod 709 is slidably inserted into both ends of the U-shaped suspension frame 6. One end of the L-shaped positioning plate 707 is fixedly connected to the positioning slide rod 709, and the L-shaped positioning plate 707 is elastically connected to the inner wall of the U-shaped suspension frame 6 via the positioning spring 710. Under the action of the positioning slide rod 709 and the positioning spring 710, the two clamping parts 704 are initially shaped like an "X," allowing the clamping parts 704 to move towards both sides of the material when they move downwards, and allowing the two clamping parts 704 to fit tightly against both sides of the material. Furthermore, the clamping parts 704 are connected to the L-shaped positioning plate 707 via the hinge shaft 708, which does not affect the rotation of the clamping parts 704.

[0024] Based on the above description Figure 9The pin positioning assembly 8 includes a positioning pin 801, a magnetic plate 802, and a handle 803. The positioning pin 801 is inserted into corresponding positioning pin holes on the U-shaped suspension frame 6 and the square positioning strip 702. The magnetic plate 802 is fixed to one end of the positioning pin 801 and is magnetically connected to the U-shaped suspension frame 6. The handle 803 is fixed to the outer wall of the magnetic plate 802. When it is necessary to fix the square positioning strip 702, the handle 803 is held to insert the positioning pin 801 into the corresponding positioning pin hole of the U-shaped suspension frame 6 and the square positioning strip 702, and the magnetic plate 802 is magnetically fixed to the U-shaped suspension frame 6. When the clamping part 704 moves down to both sides of the material and is close to the material, the square positioning strip 702 is positioned to prevent the clamping part 704 from moving laterally during the rotation and clamping of the material, ensuring that the two clamping parts 704 stably clamp the material and ensuring the accuracy and reliability of the clamping operation.

[0025] Based on the above description Figure 8 The pushing and pressing assembly 9 includes a bidirectional threaded rod 901, a pushing threaded block 902, a first L-shaped push plate 903, and a second L-shaped push plate 904. The bidirectional threaded rod 901 is rotatably mounted on the inner wall of the U-shaped suspension frame 6. The pushing threaded block 902 is threadedly sleeved on the bidirectional threaded rod 901, and there are two pushing threaded blocks 902. The two pushing threaded blocks 902 are located at the opposite thread ends of the bidirectional threaded rod 901. The first L-shaped push plate 903 and the second L-shaped push plate 904 are fixed to the bottom of the two pushing threaded blocks 902, and the first L-shaped push plate 903 and the second L-shaped push plate 904 are symmetrically distributed. One end of the first L-shaped push plate 903 and the second L-shaped push plate 904 is located inside the two clamping parts 704. When the bidirectional threaded rod 901 is rotated, the two pushing threaded blocks 902, which are located at their opposite thread ends, will move closer to or further away from each other. The pusher block 902 moves, causing the first L-shaped pusher plate 903 and the second L-shaped pusher plate 904, which are symmetrically distributed at the bottom, to move synchronously. One end of each pusher plate is located inside the two clamping parts 704, thereby pushing the top of the clamping parts 704 to separate or move closer, realizing flexible adjustment of the clamping force to stably clamp different materials. The pusher extrusion assembly 9 also includes a servo motor 905 and a transverse smooth rod 906. The servo motor 905 is fixed on the outer wall of the U-shaped suspension frame 6. One end of the bidirectional threaded rod 901 is fixedly connected to the output shaft of the servo motor 905. The transverse smooth rod 906 is fixed on the inner wall of the U-shaped suspension frame 6, and the pusher block 902 slides on the transverse smooth rod 906. When the servo motor 905, which is fixed on the outer wall of the U-shaped suspension frame 6, is started, its output shaft drives the bidirectional threaded rod 901 to rotate. Because the push threaded block 902 is slidably sleeved on the transverse smooth rod 906, under the reverse thread action of the bidirectional threaded rod 901, the two push threaded blocks 902 move closer or further away from each other along the transverse smooth rod 906, thereby driving the first L-shaped push plate 903 and the second L-shaped push plate 904 connected at the bottom to move, so as to achieve precise control of the clamping action of the clamping part 704.

[0026] In use, the drive motor 304 of the self-cleaning walking drive assembly 3 is turned on, the walking wheels 302 move in the walking limit groove, the cleaning roller 306 rotates synchronously to clean the limit groove, and the scanning camera positions the material. After reaching the position, the pin positioning assembly 8 is removed, the vertical cylinder 5 drives the U-shaped suspension frame to descend, the extended clamping assembly 7 moves down, the rotating contact roller 706 contacts the material, and the protruding support part 705 reaches the bottom of the material. The pin positioning assembly 8 is then inserted again, the servo motor 905 of the pushing extrusion assembly 9 is started, the bidirectional threaded rod 901 rotates, causing the two pushing threaded blocks 902 to drive the first L-shaped push plate 903 and the second L-shaped push plate 904 to move, so that the bottom of the clamping part 704 approaches and clamps the material, and finally the vertical cylinder 5 rises to transfer the material.

[0027] The foregoing has shown and described the basic principles, main features and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments.
