Description

Technical Field

[0001] The present invention relates to the field of cranes, and specifically to a counterweight lifting device based on mine gravity energy storage. Background Art

[0002] Mine gravity energy storage is an innovative energy storage technology that utilizes the depth of abandoned mines and the principle of gravity to convert excess electrical energy into mechanical energy for storage and release for power generation when needed; The principle is to utilize the depth of the mine to store energy by lifting heavy objects such as stones or metal blocks to the wellhead. During peak electricity demand, the heavy objects descend to drive a generator to generate electricity, converting potential energy into electrical energy; The existing Chinese patent with the publication number CN218231507U discloses a lifting mechanism and a lifting device. The lifting mechanism includes: a mounting main body extending along a first direction; and a lifting assembly including a lifting member and a connecting member. The lifting member includes a lifting main body and a plurality of lifting portions. The connecting member is connected between the lifting main body and the mounting main body. A sliding hole extending along a second direction Y is provided on the lifting main body. The second direction intersects the first direction X. The sliding hole penetrates through opposite sides of the lifting main body along a third direction. All the lifting portions are arranged side by side along the second direction on the lifting main body, and each lifting portion is slidably disposed through the sliding hole and used to connect a workpiece to be lifted, and the distance between at least two adjacent lifting portions is adjustable; wherein, the third direction intersects both the first direction and the second direction. The lifting mechanism and the lifting device provided in this application can improve the assembly efficiency of the workpiece to be lifted to meet the assembly production capacity requirements of the workpiece to be lifted.

[0003] However, the lifting mechanism and the lifting device still have the following defects: 1. The counterweight quantity of the traditional lifting structure for heavy objects is not adjustable, and the fixing method of the heavy objects is not stable enough. The lifting structure cannot firmly grasp the heavy objects during the falling process, which may cause the heavy objects to fall from a height and result in accidents; 2. The counterweight height of the traditional lifting structure for heavy objects is not adjustable. Different heights result in different potential energies of the falling heavy objects, thus affecting the collected electricity. Summary of the Invention

[0004] The purpose of the present invention is to provide a counterweight lifting device based on mine gravity energy storage to solve the problems raised in the above background art.

[0005] The technical solution of the present invention is: a counterweight lifting device based on mine gravity energy storage, including a support frame and a fixed base. A lifting structure is installed on one side of the support frame, and a counterweight structure is installed on one side of the lifting structure. The lifting structure lifts the counterweight structure, and the counterweight structure can adjust the number of counterweight blocks; Among them, the lifting structure includes a telescopic push rod and a connecting component. The telescopic push rod drives the counterweight structure to move up and down through the connecting component to lift the counterweight structure. Among them, the counterweight structure includes a metal frame and counterweight metal rods. The counterweight metal rods are installed inside the metal frame, and multiple groups of counterweight metal rods are provided.

[0006] Further, a square hinge is installed at the output end of the telescopic push rod, and hinge rods penetrate through both sides of the square hinge. Among them, transmission gears are hinged to both sides of the hinge rod, and a transmission chain is installed at the top of the transmission gear. A meshing transmission relationship exists between the transmission gear and the transmission chain.

[0007] Further, U-shaped protective covers are installed on both sides of the hinge rod, and the U-shaped protective covers are sleeved on the top of the transmission gear. Among them, both ends of the U-shaped protective cover are connected through the transmission chain.

[0008] Further, a fixed connecting piece is installed at one end of the transmission chain, and the transmission chain is fixedly connected to the fixed base through the fixed connecting piece. Among them, a T-shaped connecting piece is installed at one end of the transmission chain close to the metal frame, and the transmission chain is fixedly connected to the metal frame through the T-shaped connecting piece.

[0009] Further, limiting slide rails are installed on both sides of one end of the support frame close to the metal frame, and limiting sliders are slidably connected to the side of the limiting slide rail away from the support frame. The side of the limiting slider away from the limiting slide rail is connected to the metal frame.

[0010] Further, triangular side plates are installed on both sides of the metal frame. Among them, preset anti-slip grooves are inlaid at both ends of the metal frame, and the preset anti-slip grooves are in the shape of a through groove with a straight top and a circular arc bottom.

[0011] Further, an anti-slip metal shaft penetrates through the middle position of the counterweight metal rod, and both sides of the anti-slip metal shaft penetrate through the preset anti-slip grooves. The anti-slip metal shaft is in the shape of a plug with a straight top and a circular arc bottom that matches the preset anti-slip grooves.

[0012] Further, preset through holes penetrate through both ends of both sides of the anti-slip metal shaft, and special-shaped insertion shafts penetrate through the inside of the preset through holes. Among them, the top of the special-shaped insertion shaft penetrates through the preset through hole, and the bottom of the special-shaped insertion shaft surrounds and winds around the bottom half of the anti-slip metal shaft.

[0013] Further, protective pressure strips are installed at the top of both sides of the metal frame, and the protective pressure strips are arranged on both sides of the top of the counterweight metal rod.

[0014] The present invention provides a counterweight lifting device based on mine gravity energy storage through improvements. Compared with the prior art, it has the following improvements and advantages: First, by installing multiple groups of heavy metal rods and adjusting the number of heavy metal rods, the number of counterweights of the device can be adjusted. Since counterweight blocks with different numbers have different weights and different falling potential energies, the anti-slip metal shaft is inserted through and penetrates the preset anti-slip groove on one side of the heavy metal rod and the metal frame to fix the heavy metal rod inside the metal frame. In addition, the top ends of the anti-slip metal shaft and the preset anti-slip groove are parallel, which plays a role in preventing the heavy metal rod from rolling and moving. Moreover, the protruding parts on both sides of the anti-slip metal shaft penetrating the preset anti-slip groove are provided with preset through holes, and the special-shaped insertion shaft penetrates the preset through holes. The role of the special-shaped insertion shaft is to fix both ends of the anti-slip metal shaft from other directions. In addition, the bottom end of the special-shaped insertion shaft is arc-shaped and fits the bottom end of the preset through hole, and the top end of the special-shaped insertion shaft is linearly penetrated through the preset through hole, strengthening the fixing effect of the heavy metal rod to be more stable and facilitating the disassembly of the heavy metal rod. In addition, multiple groups of preset anti-slip grooves are provided and evenly distributed on both sides of the metal frame, which is convenient for sorting the heavy metal rods, enabling the counterweight blocks to be evenly and neatly distributed, and avoiding accidents caused by unstable fixation and falling from a high place due to chaotic placement during the falling process of heavy objects.

[0015] Second, by starting the telescopic push rod to push the articulated rod and the transmission gears on both sides to move upward, the weight height of the heavy object lifted by the lifting structure is adjusted, and the height of the heavy object is adjusted according to the required potential energy, so as to adjust the collected electricity. Because the potential energies of different heavy objects falling are different, but it also requires power to lift the heavy object and maintain its height.

[0016] The specific working principle is to start the telescopic push rod to push the articulated rod and the transmission gears on both sides to move upward. The lengths of the chains on both sides of the transmission chain change. The chain on the side of the transmission chain close to the counterweight structure becomes shorter, and the chain on the side of the transmission chain close to the fixed connection part becomes longer, driving the transmission gears to rotate. At this time, the counterweight structure is driven to rise by the thrust of the telescopic push rod. The function of the U-shaped protective cover is to limit the movement range of the transmission chain. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the present invention will be described in detail in conjunction with the attached Figures 1 to 11 The present invention will be described in detail. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a counterweight lifting device based on mine gravity energy storage by improvement, including a support frame 1 and a fixed base 4. A lifting structure 2 is installed on one side of the support frame 1, and a counterweight structure 3 is installed on one side of the lifting structure 2. The lifting structure 2 lifts the counterweight structure 3, and the counterweight structure 3 can adjust the number of counterweight blocks; Among them, the lifting structure 2 includes a telescopic push rod 201 and a connection assembly. The telescopic push rod 201 drives the counterweight structure 3 to move up and down through the connection assembly to lift the counterweight structure 3. The output end of the telescopic push rod 201 is installed with a square hinge 202, and hinge rods 203 penetrate through both sides of the square hinge 202. Wherein, transmission gears 204 are hinged to both sides of the hinge rod 203. When the telescopic push rod 201 is started to push the hinge rod 203 and the transmission gears 204 on both sides to move upward, the weight balance height of the lifting structure's flag is adjusted, and the height of the heavy object is adjusted according to the required potential energy, so as to adjust the collected electricity. Because the potential energy of different heavy objects falling is different, but moving the heavy object upward and maintaining its height also requires power. And a transmission chain 206 is installed at the top of the transmission gear 204, and there is a meshing transmission relationship between the transmission gear 204 and the transmission chain 206. When starting, the chain lengths on both sides of the transmission chain 206 change, and the chain on the side of the transmission chain 206 close to the counterweight structure 3 becomes shorter. U-shaped protective covers 205 are installed on both sides of the hinge rod 203, and the U-shaped protective covers 205 are sleeved on the top of the transmission gears 204. The function of the U-shaped protective covers 205 is to limit the movement range of the transmission chain 206. Wherein, both ends of the U-shaped protective cover 205 are connected through the transmission chain 206. One end of the transmission chain 206 is installed with a fixed connector 208, and the transmission chain 206 is fixedly connected to the fixed base 4 through the fixed connector 208. When rising, the chain on the side of the transmission chain 206 close to the fixed connector 208 becomes longer and drives the transmission gear 204 to rotate. Wherein, a T-shaped connector 207 is installed at one end of the transmission chain 206 close to the metal frame 301, and the transmission chain 206 is fixedly connected to the metal frame 301 through the T-shaped connector 207. At this time, the counterweight structure 3 is driven to rise by the thrust of the telescopic push rod 201. Limit sliding rails 210 are installed on both sides of one end of the support frame 1 close to the metal frame 301, and limit sliding blocks 209 are slidably connected to the side of the limit sliding rails 210 away from the support frame 1, and the side of the limit sliding blocks 209 away from the limit sliding rails 210 is connected to the metal frame 301. Wherein, the counterweight structure 3 includes a metal frame 301 and weight metal rods 303. The weight metal rods 303 are installed inside the metal frame 301, and multiple groups of weight metal rods 303 are provided; by installing multiple groups of weight metal rods 303, the number of weight metal rods 303 is adjusted, so as to adjust the weight of the device, because the weights of different numbers of configuration blocks are different, and their falling potential energies are also different. Triangular side plates 302 are installed on both sides of the metal frame 301. Among them, both ends of the metal frame 301 are inlaid with preset anti-slip grooves 305, and the preset anti-slip grooves 305 are in the shape of a through groove with a straight top and an arc-shaped bottom; by inserting and passing the anti-slip metal shaft 304 through the preset anti-slip groove 305 on one side of the weight metal rod 303 and the metal frame 301, the weight metal rod 303 is fixed inside the metal frame 301. The anti-slip metal shaft 304 passes through the middle position of the weight metal rod 303, and both sides of the anti-slip metal shaft 304 penetrate the preset anti-slip groove 305. The anti-slip metal shaft 304 is in the shape of a plug with a straight top and an arc-shaped bottom that matches the preset anti-slip groove 305; in addition, the top of the anti-slip metal shaft 304 and the preset anti-slip groove 305 are parallel, which plays a role in preventing the weight metal rod 303 from rolling and moving. Both ends on both sides of the anti-slip metal shaft 304 penetrate the preset through holes 307, and the inside of the preset through holes 307 penetrates the special-shaped plug shaft 306. Among them, the top of the special-shaped plug shaft 306 penetrates the preset through hole 307, and the bottom of the special-shaped plug shaft 306 is in a surrounding shape and wraps around the bottom half of the anti-slip metal shaft 304; the function of the special-shaped plug shaft 306 is to fix both ends of the anti-slip metal shaft 304 from other directions, and the bottom of the special-shaped plug shaft 306 is arc-shaped and fits the bottom of the preset through hole 307, and the top of the special-shaped plug shaft 306 penetrates the preset through hole 307 in a straight line, strengthening the fixing effect of the weight metal rod 303 to be more stable and facilitating the disassembly of the weight metal rod 303. In addition, multiple groups of preset anti-slip grooves 305 are provided and are evenly distributed on both sides of the metal frame 301, which is convenient for sorting the weight metal rods 303, so that the counterweight blocks can be evenly and neatly distributed, avoiding accidents caused by unstable fixing due to chaotic placement during the falling process of heavy objects and falling from a high place. Protective pressure strips 308 are installed at the tops of both sides of the metal frame 301, and the protective pressure strips 308 are arranged on both sides of the top of the weight metal rod 303.

[0021] Working principle: First, by installing multiple sets of counterweight metal rods 303, the number of counterweight metal rods 303 is adjusted, thereby adjusting the number of counterweights of the device. Since the weights of different numbers of configuration blocks are different, their falling potential energies are also different. And by inserting the anti-slip metal shaft 304 into and passing through the preset anti-slip groove 305 on one side of the counterweight metal rod 303 and the metal frame 301, the counterweight metal rod 303 is fixed inside the metal frame 301. In addition, the top ends of the anti-slip metal shaft 304 and the preset anti-slip groove 305 are parallel, which plays a role in preventing the counterweight metal rod 303 from rolling and moving. And the anti-slip metal shaft 304 passes through the preset through holes 307 provided on both sides of the protruding part of the preset anti-slip groove 305. The special-shaped insertion shaft 306 passes through the preset through holes 307. The function of the special-shaped insertion shaft 306 is to fix both ends of the anti-slip metal shaft 304 from other directions. In addition, the bottom end of the special-shaped insertion shaft 306 is arc-shaped and fits the bottom end of the preset through hole 307, and the top end of the special-shaped insertion shaft 306 is linearly passed through the preset through hole 307, which strengthens the fixing effect of the counterweight metal rod 303 to be more stable and is convenient for disassembling the counterweight metal rod 303. In addition, multiple groups of preset anti-slip grooves 305 are provided and are equally spaced on both sides of the metal frame 301, which is convenient for sorting the counterweight metal rods 303, so that the counterweight blocks can be evenly and neatly distributed, avoiding accidents caused by unstable fixing due to chaotic placement during the falling process of heavy objects and falling from a high place.

[0022] Then, by starting the telescopic push rod 201 to push the articulated rod 203 and the transmission gears 204 on both sides to move upward, the height of the heavy object counterweight of the lifting structure flag is adjusted, and the height of the heavy object is adjusted according to the required potential energy, so as to adjust the collected electric power. Because the potential energies of different heavy objects falling are different, but moving the heavy object upward and maintaining the height of the heavy object also requires power.

[0023] Finally, by starting the telescopic push rod 201 to push the articulated rod 203 and the transmission gears 204 on both sides to move upward, the lengths of the chains on both sides of the transmission chain 206 change. The chain on the side of the transmission chain 206 close to the counterweight structure 3 becomes shorter, and the chain on the side of the transmission chain 206 close to the fixed connecting piece 208 becomes longer, and drives the transmission gear 204 to rotate. At this time, the counterweight structure 3 is driven to rise by the thrust of the telescopic push rod 201. The function of the U-shaped protective cover 205 is to limit the movement range of the transmission chain 206.
