[0002] Scaffolding is a working platform erected to facilitate construction and ensure construction safety. Scaffolding is usually made of steel pipes or I-beams and other profiles, fixed and connected by various forms of fasteners. In mining projects, scaffolding is often quite high and is often erected in locations with limited space, such as mine shafts, which is not conducive to the transportation of materials. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a mining engineering scaffold with material lifting function, which effectively solves the problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A mining engineering scaffold with material lifting function, comprising:

[0006] A truss unit, the truss unit comprising a top frame and a bottom frame;

[0007] The top ring and the bottom ring are fixedly installed on the top frame and the bottom frame respectively by fasteners. The truss units are fixedly installed end to end. The top ring in the lower truss unit is the bottom ring in the upper truss unit.

[0008] The track rods are fixedly installed at both ends of the upper top ring and the lower bottom ring, and multiple track rods are provided, which are evenly distributed inside the upper top ring and the lower bottom ring;

[0009] A fixing ring is installed on the upper end of the uppermost track rod;

[0010] A lifting pulley is installed at the center of the fixed ring, and a sling is provided along the channel formed by the plurality of rail rods;

[0011] A crane, wherein the output end of the crane is fixedly connected to one end of the sling;

[0012] A suspended platform is fixedly connected to the end of the sling away from the crane, and the platform is located within a channel formed along a plurality of the track rods.

[0013] Optionally, multiple support wheels are fixedly connected to the outside of the suspended basket, and the support wheels are provided with matching annular grooves on their sides. The track rod corresponds one-to-one with the support wheel.

[0014] Optionally, an obstacle avoidance frame is hinged to the outside of the suspended basket, the support wheel is installed at the end of the obstacle avoidance frame away from the suspended basket, and an obstacle avoidance spring is fixedly installed between the obstacle avoidance frame and the track rod.

[0015] Optionally, the stroke of the obstacle avoidance spring is less than the depth of the adapting ring groove.

[0016] Optionally, the suspended platform includes multiple L-shaped tubes, with anti-fall bars hinged to the sides of the L-shaped tubes. Anti-fall springs are provided between the anti-fall bars and the L-shaped tubes. Multiple slings are provided at one end of the suspended platform, corresponding one-to-one with the L-shaped tubes. The end of the sling passes through the L-shaped tube and is fixedly connected to the anti-fall bar. Multiple anti-fall protrusions are arrayed along the axial direction of the track rod. When the anti-fall bar is pushed upward by the anti-fall springs, its end is attached to the side wall of the track rod.

[0017] Optionally, the anti-fall protrusion has at least a flat upper surface.

[0018] Optionally, the L-shaped tube bend is an arc-shaped bend.

[0019] Optionally, the anti-fall bar has a locking groove at one end near the track bar, and the locking groove is adapted to the shape of the track bar.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting up an upper top ring, a lower bottom ring, and a track rod to form a channel, the suspended basket can transport materials within the channel. The suspended basket is located inside the truss unit, which does not occupy the space outside the scaffolding and can directly transport materials to the work platform. The suspended basket is located inside the truss unit, which makes it safer for workers to pick up materials.

[0022] 2. The suspended platform operates within a channel formed by multiple track rods, reducing the possibility of swaying and potential dangers during lifting and lowering. By installing support wheels, which run along the track rods through matching annular grooves, the swaying space of the suspended platform is restricted by the track rods, further improving the stability of the suspended platform's lifting and lowering.

[0023] 3. A fall arrestor is installed, which is hinged to the suspended platform and pulled close to the platform by slings. A fall arrestor spring is installed between the fall arrestor and the platform. Under normal conditions, the weight of the platform causes the slings to pull the fall arrestor closer to the platform. In the event of an accidental fall, the slings cannot provide adequate tension, and the fall arrestor spring drives the fall arrestor away from the platform and closer to the track pole. The track pole is equipped with fall arrestor protrusions. When the fall arrestor falls, it is supported on the top of the fall arrestor protrusions to prevent it from falling and causing greater danger. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 and Figure 2 This utility model discloses a mining engineering scaffold with material lifting function, comprising a truss unit 1. The truss unit 1 includes a top frame 11 and a bottom frame 12. The top frame 11 and the bottom frame 12 are respectively fixedly installed with an upper top ring 21 and a lower bottom ring 22 via fasteners. The truss unit 1 is fixedly installed end-to-end. The upper top ring 21 in the lower truss unit 1 is the lower bottom ring 22 in the upper truss unit 1. Multiple track rods 23 are installed between the upper top ring 21 and the lower bottom ring 22. 23 are evenly distributed on the inner sides of the upper top ring 21 and the lower bottom ring 22. A fixed ring 24 is installed on the upper end of the uppermost track rod 23. A lifting pulley 31 is installed in the center of the fixed ring 24. A sling is set along the channel formed by multiple track rods 23. A crane 32 is installed on the truss unit 1. One end of the sling is fixedly connected to the output end of the crane 32. A basket 33 is fixedly connected to the end of the sling away from the crane 32. The basket 33 is located in the channel formed by multiple track rods 23.

[0032] Specifically, multiple upper top rings 21, lower bottom rings 22 and track rods 23 form a channel space. The suspended basket 33 runs in this channel space through a crane 32, slings and lifting pulleys 31. The upper top rings 21 and lower bottom rings 22 are fixedly connected to the truss unit 1 by fasteners.

[0033] In this way, by setting up the upper top ring 21, the lower bottom ring 22 and the track rod 23 to form a channel, the suspended basket 33 can transport materials in the channel. The suspended basket 33 is partially set inside the truss unit 1, which does not occupy the space outside the scaffolding, and can also transport materials directly to the work platform. At the same time, the suspended basket 33 is partially set inside the truss unit 1, which makes it safer for workers to pick up materials.

[0034] In some feasible methods, the scaffolding is usually a rectangular truss structure formed by steel pipes fixedly connected by fasteners. Truss unit 1 is a unit space of one layer. The top frame 11 and the bottom frame 12 are the truss structures at the top and bottom of the unit space. The upper top ring 21 and the lower bottom ring 22 can be circular rings or other shapes. The upper top ring 21 and the lower bottom ring 22 are fixedly connected to the top frame 11 and the bottom frame 12 by fasteners or other means. The track rod 23 can be made of steel pipe. The upper top ring 21 and the lower bottom ring 22 are provided with connecting rings on the inner side. The track rod 23 is inserted into the connecting ring and fixed by bolts or other means. For easy installation, the lower end of the track rod 23 is provided with a plug end with the same outer diameter as the upper inner diameter. During installation, the plug end is inserted into the upper end of the lower track rod 23 and fixedly connected by bolts or other means.

[0035] The fixed ring 24 has the same structure as the upper top ring 21 and the lower bottom ring 22. A bracket is fixedly installed on the inner side of the fixed ring 24 to facilitate the installation of the lifting pulley 31.

[0036] As a specific implementation of a mining engineering scaffold with material lifting function provided in the application, please refer to Figure 2 and Figure 3 Multiple support wheels 34 are fixedly connected to the outside of the suspended basket 33. The support wheels 34 have matching annular grooves 341 on their sides. The track rod 23 corresponds to the support wheels 34 one by one.

[0037] Overall, the suspended platform 33 operates within the channel formed by multiple track rods 23, reducing the possibility of swaying and causing danger during the lifting and lowering of the suspended platform 33. By setting support wheels 34, the support wheels 34 run along the track rods 23 through the adapting annular grooves 341, which restricts the swaying space of the suspended platform 33 by the track rods 23, further improving the stability of the lifting and lowering of the suspended platform 33.

[0038] Furthermore, an obstacle avoidance frame 35 is hinged to the outside of the suspended basket 33. A support wheel 34 is installed at the end of the obstacle avoidance frame 35 away from the suspended basket 33. An obstacle avoidance spring 351 is fixedly installed between the obstacle avoidance frame 35 and the track rod 23.

[0039] It should be understood that during the construction of the mining project, other debris may adhere to the side wall of the track rod 23. By setting up the obstacle avoidance frame 35 and the obstacle avoidance spring 351, when the support wheel 34 runs to the obstacle position, it will retract towards the basket 33 through the obstacle avoidance spring 351, reducing the possibility of being stuck by debris.

[0040] Furthermore, the stroke of the obstacle avoidance spring 351 is less than the groove depth of the adapting ring groove 341.

[0041] It should be understood that by setting the stroke of the obstacle avoidance spring 351 to be less than the groove depth of the matching ring groove 341, the possibility of the support wheel 34 jumping too much and detaching from the track rod 23 is reduced.

[0042] In some feasible embodiments, the obstacle avoidance frame 35 is a rectangular rod, with one end of the obstacle avoidance frame 35 hinged to the track rod 23 and the other end fixedly connected to a U-shaped frame. The support wheel 34 is rotatably installed in the U-shaped frame, and the shape of the fitting ring groove 341 is set according to the shape of the outer side of the track rod 23.

[0043] As another specific embodiment of the mining engineering scaffolding with material lifting function provided in the application, please refer to [link / reference needed]. Figure 2 and Figure 3 The suspended platform 33 includes multiple L-shaped tubes 331. Anti-fall rods 332 are hinged to the sides of the L-shaped tubes 331. Anti-fall springs 333 are provided between the anti-fall rods 332 and the L-shaped tubes 331. Multiple slings are provided at one end of the suspended platform 33, corresponding one-to-one with the L-shaped tubes 331. The ends of the slings pass through the L-shaped tubes 331 and are fixedly connected to the anti-fall rods 332. Multiple anti-fall protrusions 334 are arrayed along the axial direction of the track rod 23. When the anti-fall rods 332 are pushed upward by the anti-fall springs 333, their ends are attached to the side wall of the track rod 23.

[0044] In specific application scenarios, especially in mining engineering, particularly in mine tunnels, high scaffolding may be required, resulting in a significant lifting distance for the suspended platform 33. A fall arrestor 332 is installed, hinged to the suspended platform 33 and pulled close to it by slings. A fall arrestor spring 333 is installed between the fall arrestor 332 and the suspended platform 33. Under normal conditions, the weight of the suspended platform 33 causes the slings to pull the fall arrestor 332 closer to the platform. In the event of an accidental fall, if the slings cannot provide sufficient tension, the fall arrestor spring 333 will cause the fall arrestor 332 to move away from the platform 33 and closer to the track pole 23. The track pole 23 has a fall arrestor protrusion 334, which supports the fall arrestor 332 as it falls, preventing a greater danger from a fall.

[0045] Furthermore, the anti-fall rod 332 has a locking groove 335 at one end near the track rod 23, and the locking groove 335 is adapted to the shape of the track rod 23.

[0046] It should be understood that by setting the locking groove 335, the contact area between the fall arrestor 332 and the track rod 23 is increased, which facilitates the support of the fall arrestor 332 by the fall arrestor protrusion 334.

[0047] In some feasible methods, when the fall arrestor 332 is a rectangular rod and the track rod 23 is a cylindrical rod, a semi-circular ring is fixedly installed at the lower end of the fall arrestor 332. The side of the semi-circular ring near the track rod 23 has a slot 335. To reduce damage to the sling, the bend of the L-shaped tube 331 is an arc bend. The sling passes through the L-shaped tube 331 and connects to the fall arrestor 332. To facilitate the fall arrestor 332 forming support on the upper end of the fall arrestor protrusion 334, the upper surface of the fall arrestor protrusion 334 is at least flat. The fall arrestor protrusion 334 can be set as a ring.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
