Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, and in particular to a material safe transfer device for steep terrain. Background Technology

[0002] In mining, engineering construction, and emergency rescue operations, material transfer operations are often required in steep terrain areas, such as the transfer of crushed stone and loading of explosives at mine blast holes. However, traditional methods for transferring materials in steep terrain have the following problems.

[0003] On the one hand, manual material handling is inefficient, incurring significant labor and time costs. Furthermore, on steep terrain, workers are at risk of accidental falls during walking and operation, posing a substantial safety hazard. On the other hand, existing protective measures are often inadequate. In steep terrain, falling rocks or materials dropping during manual handling can also pose a safety threat to personnel and equipment below. Moreover, existing material transfer and protection devices are mostly integrated designs, difficult to disassemble, and extremely inconvenient to handle. Additionally, the materials used in these devices are largely non-recyclable, resulting in resource waste and high costs.

[0004] Therefore, based on the above problems, it is of great practical significance to develop a material transfer device that can be applied to steep terrain and has safety protection, efficient handling and economic and environmental protection. Utility Model Content

[0005] The main purpose of this invention is to propose a material transfer device for steep terrain, aiming to solve the technical problems of low human efficiency and safety risks in the process of material transfer in steep terrain.

[0006] To achieve the above objectives, the material transfer device for steep terrain proposed in this utility model includes a transfer device and a track base; The transfer device includes a lifting mechanism and a turning mechanism. The lifting mechanism includes a basket and a lifting drive component for driving the basket to move up and down. The turning mechanism includes a frame and a plurality of casters located at the bottom of the frame. The lifting mechanism is located at the top of the frame. The track base includes a ring-shaped track and multiple support legs connected to the ring-shaped track. The multiple casters are arranged to roll within the ring-shaped track, and the multiple support legs are connected to a protective net for interception.

[0007] Optionally, the lifting mechanism further includes a lifting chain and a chain winding shaft. The lifting drive can drive the chain winding shaft to rotate. One end of the lifting chain is wound around the chain winding shaft, and the other end is connected to the basket.

[0008] Optionally, the lifting drive component is a motor.

[0009] Optionally, a guardrail is movably installed at the material inlet of the suspended basket.

[0010] Optionally, the frame includes a crossbeam and two supports for supporting the crossbeam, and the lifting mechanism is mounted on the crossbeam.

[0011] Optionally, each of the two pillars is provided with a base at its bottom, and the bottom of the base is rotatably connected to two casters.

[0012] Optionally, the annular track includes multiple arc-shaped tracks, which are fixedly connected to form the annular track.

[0013] Optionally, the upper surface of the annular track is provided with an annular groove, and the plurality of universal wheels are rolled within the groove.

[0014] Optionally, the bottom of the annular track is provided with multiple mounting slots, and the multiple legs are nested in the multiple mounting slots.

[0015] Optionally, a shock-absorbing pad is provided between the top of the support leg and the bottom of the mounting groove.

[0016] In this technical solution, for material transfer on steep terrain, the legs of the track base are first embedded into the ground to level the circular track. Then, the wheels of the transfer device are placed inside the circular track. The lifting drive mechanism moves the basket up and down to load materials. Rotating the wheels changes the basket's position, allowing materials to be transferred between different elevations. This device significantly improves the efficiency of material transfer in steep terrain, saving labor and time costs. Simultaneously, the protective netting of the track base effectively prevents falling debris and personnel from falling, improving the safety of personnel and equipment. Attached Figure Description

[0024] Currently, manual transport on steep terrain is inefficient, and workers may fall during walking and operation, posing a significant safety risk. Furthermore, when working on steep terrain, falling rocks or materials may be caused by manual handling, posing a safety threat to personnel and equipment below.

[0025] Therefore, this utility model provides a material transfer device for steep terrain. Figure 1-3 This invention provides an embodiment of a material transfer device for steep terrain. Please refer to [link / reference]. Figure 1-3 The material transfer device 100 for steep terrain includes a transfer device 1 and a track base 2.

[0026] Specifically, the transfer device 1 includes a lifting mechanism 11 and a turning mechanism 12. The lifting mechanism 11 includes a basket 112 and a lifting drive component 113 for driving the basket 112 to move up and down. Similar to some common lifting structures, it can transport heavy objects by means of ropes and wheels. In this embodiment, the lifting mechanism 11 also includes a metal chain 114, a chain shaft 115, and a housing 116. The lifting drive component 113 is fixedly installed in the housing 116, and the chain shaft 115 is rotatably connected in the housing 116. One end of the chain 114 is wound around the chain shaft 115, and the other end is connected to the basket 112 (in this embodiment, the basket is tied with a nylon rope and then connected to the chain). The lifting drive component 113 can directly drive or indirectly drive the chain shaft 115 to rotate through a transmission structure such as a reduction gear, so that the chain 114 can be retracted and extended on the chain shaft 115, thereby realizing the up and down movement of the basket 112.

[0027] In a preferred embodiment, a pulley (not shown in the figure) may also be rotatably installed inside the housing 116. The pulley and the chain shaft 115 are arranged in the same horizontal direction. The chain 114 is wound around the chain shaft 115 and then slidably connected to the pulley, so that the tension is evenly distributed to each section of the chain 114, thereby improving the stability of lifting.

[0028] In this embodiment, the lifting drive component 113 is a motor, which is fixed inside the housing 116 by bolts. The chain shaft 115 is rotatably mounted inside the housing 116 via bearings. The chain shaft 115 is provided with splines (not shown in the figure) and is connected to the motor drive via a reduction gear to increase the torque of the chain shaft 115, thereby lifting heavier materials at the rated power of the motor. Preferably, the motor has an overload protection function. When the weight of the lifted material exceeds a set threshold, the motor automatically shuts down, stopping the lifting operation to prevent equipment damage and material falling.

[0029] Please see Figure 2The suspended platform 112 is made of thickened acrylic sheet, which has high light transmittance, ensuring both a certain load-bearing capacity and easy observation of the material's condition. Especially in mining blasting operations, when loading explosives at the blast holes, the placement of the explosives can be observed through the suspended platform 112. The suspended platform 112 is roughly cuboid in shape with an opening at the top. One of the four side panels is shorter, and the notch formed above it matches the top opening, facilitating loading and unloading. Furthermore, a guardrail 117 is rotatably installed at this notch; lifting the guardrail 117 allows for loading and unloading, while lowering it prevents materials from falling during hoisting.

[0030] The steering mechanism 12 includes a frame 121, which consists of a crossbeam 1211, two supports 1212, and a base 1213. The crossbeam 1211 is a square bar arranged approximately horizontally, with supports 1212 connected to both ends. The two supports 1212 are square bars arranged approximately vertically, and each support 1212 has a base 1213 connected to its bottom end. The crossbeam 1211 and supports 1212, and the supports 1212 and bases 1213 are fixedly connected with bolts to facilitate assembly, disassembly, and handling. To improve the stability of the crossbeam 1211, each support 1212 is also provided with diagonal braces 1214 on both sides. The two diagonal braces 1214 are fixedly connected to the crossbeam 1211 and the base 1213, respectively. The triangular structure enhances the stability of the crossbeam 1211 and prevents it from tilting in the forward and backward directions.

[0031] The lifting mechanism 11 is located on top of the frame 121. The housing 116 of the lifting mechanism 11 is connected to the crossbeam 1211 by nesting. The open end of the housing 116 is fitted onto the crossbeam 1211 and can slide relative to it. The housing 116 has a through hole, and the crossbeam 1211 has several screw holes and / or positioning holes distributed along the length of the crossbeam 1211. After the installation position of the lifting mechanism 11 on the crossbeam 1211 is determined, the housing 116 is fixed by bolts and / or pins, thereby installing the entire lifting mechanism 11 on the crossbeam 1211.

[0032] To implement the redirection and transfer function of transfer device 1, please refer to... Figure 2 In this embodiment, the bottom of the frame 121 is provided with multiple casters 122. Specifically, the bases 1213 on both sides of the frame 121 are each equipped with two casters 122, and each caster 122 is fixed to the bottom of the base 1213 by bolts.

[0033] It should be noted that the caster wheel 122 is a common structure in the prior art. This structure is generally equipped with a ball bearing. The outer ring of the ball bearing is fixedly connected to the base 1213, and the inner ring is connected to the wheel frame (not shown in the figure) to realize the 360° rotation of the wheel frame relative to the base 1213 in the horizontal plane. At the same time, this structure is also equipped with a wheel that rotates counterclockwise or clockwise in the forward or backward direction of the base 1213.

[0034] In addition, the self-locking function of the 122 caster wheels is generally achieved through a built-in braking structure, such as pressing a button on the wheel axle or moving a latch to lock the wheel direction and restrict rolling. This is a common fixing method and will not be described in detail here.

[0035] Please see Figure 1 The track base 2 includes an annular track 21 and multiple legs 22 connected to the annular track 21. When installing the track base 2 on steep terrain, the legs 22 of different lengths need to be inserted into the ground, and the legs 22 need to be connected to the annular track 21 to achieve stable support. The connection methods between the legs 22 and the annular track 21 include threaded connection, nesting, and tight fit.

[0036] In this embodiment, the bottom of the annular track 21 is provided with an annular groove or multiple mounting grooves (not shown in the figure), and multiple legs 22 are nested in the annular groove or multiple mounting grooves to support the annular track 21. This nesting method has high assembly efficiency and good stability, with fewer stress joints and misalignments. Furthermore, for ease of loading, unloading and transportation, the annular track 21 is composed of multiple arc-shaped tracks, which are fixedly connected together by bolts to form the annular track 21.

[0037] To reduce the rigid contact between the annular track 21 and the support leg 22 and improve the safety and reliability of the device, a shock-absorbing pad (not shown in the figure) is provided between the top of the support leg 22 and the bottom of the mounting groove to reduce friction and wear.

[0038] Please see Figure 1 and 3 A protective net 23 is fixedly connected to multiple outriggers 22. The protective net 23 is roughly circular and extends from the circular track 21 all the way to the ground, completely covering the area below the circular track 21 to prevent gravel from falling along steep terrain during material transfer, thereby preventing damage to personnel and equipment below. In this embodiment, the protective net 23 is connected to the outriggers 22 by binding with wire. The protective net 23 is made of high-strength steel wire mesh or nylon mesh, which can stably intercept falling gravel or other materials.

[0039] To enable the transfer device 1 to rotate on the annular track 21 of the track base 2, please refer to... Figure 1In this embodiment, the upper surface of the annular track 21 has an annular groove 211, within which the casters 122 of the transfer device 1 can roll around. In this embodiment, each base 1213 of the steering mechanism 12 has two casters 122, which effectively support the crossbeam 1211 and its load, and also allow it to roll within the annular groove 211. The width of the groove 211 is slightly larger than the width of the casters 122 to prevent them from jamming. Furthermore, it should be noted that the length of the crossbeam 1211 is less than or equal to the diameter of the annular track 21 to ensure the stability of the frame 121 during travel. In this embodiment, the length of the crossbeam 1211 is approximately 80% of the diameter of the annular track 21.

[0040] Please see Figure 3 In the technical solution, when using the material transfer device 100 on steep terrain, the bottom of the support leg 22 of the track base 2 can be embedded into the ground first, and then the support leg 22 and the annular track 21 can be nested together so that the annular track 21 is roughly on a horizontal plane. It should be noted that the loading position and the unloading position cannot be located at the center of the annular track 21.

[0041] Next, assemble the various components of the steering mechanism 12. The lifting mechanism 11 is fixedly installed on the crossbeam 1211 of the steering mechanism 12. After the transfer device 1 is assembled, place the four casters 122 of the steering mechanism 12 into the grooves 211 of the annular track 21. Push the base 1213 or the support column 1212 manually or electrically to make the wheels rotate. The transfer device 1 rotates until the lifting mechanism 11 reaches the material loading and unloading position and locks each caster. Then the entire material transfer device 100 is ready.

[0042] It should be noted that the lifting mechanism 11 should be installed close to both ends of the crossbeam 1211 so that when the transfer device 1 rotates, it can transfer the horizontal position of the basket 112 to the maximum distance. However, the installation position of the lifting mechanism 11 is still determined by the distance between the loading position, the unloading position and the annular track 21. The approximate installation position can be obtained by calculating the distance between the loading position, the unloading position and the center of the annular track 21.

[0043] When work begins, the motor drives the chain shaft 115 to rotate, which in turn pulls the chain 114 and the basket 112 to descend. After descending to the designated position (such as the blast hole), the guardrail 117 of the basket 112 is opened, and materials such as gravel are loaded into the basket 112. After loading is completed, the guardrail 117 is lowered, and then the motor drives the chain shaft 115 to rotate in the opposite direction again, which in turn pulls the chain 114 and the basket 112 to rise.

[0044] After rising to the designated height (i.e., a height that does not cause dryness with steep terrain), the base 1213 or the support column 1212 is pushed manually or electrically to make the wheels rotate, thereby transferring the basket 112 and the material between different heights of terrain. When it reaches the unloading position, the basket 112 is lowered and the guardrail 117 of the basket 112 is opened to unload the material.

[0045] Using this device for material transfer operations can significantly improve the efficiency of material transfer in steep terrain areas, saving labor and time costs; at the same time, the protective net 23 of the track base 2 can effectively prevent gravel from sliding and personnel from falling, improving the safety of personnel and equipment.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
