[0002] In sand and gravel mining scenarios, lifting equipment is frequently used to hoist materials in order to achieve technical objectives such as raw material handling, finished product discharge, and equipment relocation.

[0003] In this scenario, the commonly used hoisting device supports the item on a platform and then connects the platform to a crane or other lifting equipment to lift and move the item. However, in this process, the difficulty in locking the balance point of the item leads to the need to frequently change the relative position of the item and the platform, ultimately resulting in a technical defect that reduces hoisting efficiency. Utility Model Content

[0010] In one possible implementation, the support component includes:

[0011] A lifting platform is used to connect to lifting equipment to achieve its lifting and translational movements; and

[0012] A support platform is provided on the lower side of the lifting platform and is used to support the items to be lifted.

[0015] The upper side of the support plate has a groove for placing items to be hoisted, and the lower side of the limiting plate has a boss suitable for embedding into the groove.

[0016] The linear drive component can drive the limiting plate to move downward until the boss is embedded in the groove, and the boss abuts against the item in the groove, thereby restricting the relative movement of the item and the support platform.

[0017] In one possible implementation, the linear drive component includes:

[0018] Two swing arms are hinged to the upper side of the limiting plate, and their hinge axes are parallel to each other; each swing arm has a hinge seat hinged to its upper end, the hinge seat being slidably connected to the lifting platform, and a transmission nut is provided on the hinge seat; and

[0019] A bidirectional screw is rotatably mounted on the lifting platform and has two threaded portions with opposite thread directions. The two threaded portions are respectively threadedly connected to the two transmission nuts, so that when the bidirectional screw rotates, the two hinge seats move towards each other or away from each other, thereby driving the limiting plate to move relative to the lifting platform in the vertical direction through the swing arm.

[0020] In one possible implementation, two strip-shaped grooves are provided on the upper side of the lifting platform, each strip-shaped groove has a guide hole at the bottom, and a baffle can be detachably connected to the opening of each strip-shaped groove.

[0021] The hinge base includes:

[0022] A connecting part is slidably disposed on the lower side of the lifting platform, and has a plug shaft that is fitted into the guide hole thereon; and

[0023] The transmission part is fixedly disposed at the upper end of the insertion shaft and is located within the strip groove;

[0024] The swing arm is hinged to the connecting part, and the transmission nut is fixedly mounted on the transmission part; a reserved groove is provided on the outer wall of the platform, which runs through the two strip grooves and is connected to the two strip grooves; the bidirectional screw is inserted into the reserved groove, and one end of the bidirectional screw is located outside the reserved groove and is connected to a drive handle.

[0025] In one possible implementation, the outer wall of the support platform has a plurality of protrusions spaced apart circumferentially thereon; the counterweight has a snap-fit ​​groove on the side facing the support platform, and the snap-fit ​​groove extends vertically to penetrate the lower end face of the counterweight to accommodate the protrusions.

[0026] In one possible implementation, the counterweight has a hollow internal structure, and its interior is used to contain the counterweight medium.

[0027] In one possible implementation, the rapid hoisting device further includes:

[0028] A water pump for connecting to an external water source and disposed on the outside of the base; the water pump has a water delivery pipe adapted to connect to any one of the counterweights.

[0029] The base includes:

[0030] A fixing part for support on the ground; and

[0031] A rotating part is rotatably disposed on the upper side of the fixed part;

[0032] The fixed part is equipped with a rotating motor, the power output axis of which is parallel to the vertical direction, and the power output end of the rotating motor is connected to the rotating part; and each gravity sensor is mounted on the rotating part.

[0033] In one possible implementation, the upper side of the base has a plurality of receiving slots spaced apart along its circumference; a plurality of gravity sensors are embedded in the plurality of receiving slots in a one-to-one correspondence, and the sensing end of each gravity sensor extends to the upper side of the base.

[0034] In one possible implementation, the base has a concave ball groove at the center of its upper side surface, and the balance plate has a convex shaft inserted into the concave ball groove on its lower side, with the end of the convex shaft connected to the bottom of the concave ball groove.

[0035] In this embodiment, by placing the object to be hoisted on the support assembly and placing the support assembly above the balance plate, it is possible to monitor whether the balance point of the object and the center of the support surface of the support assembly coincide. When the balance point of the object and the center of the support surface of the support assembly do not coincide, the support assembly can tilt the balance plate, causing a change in the corresponding gravity sensor value. Based on this, by adjusting the counterweight on the other side, the balance plate can be brought to a horizontal state, thereby quickly adjusting the support surface of the support assembly to a horizontal state, allowing the object to be hoisted to move along a horizontal plane, ensuring the stability of the object hoisting process.

[0036] The rapid hoisting device for sand and gravel mines provided in this embodiment, compared with the prior art, can quickly adjust the support surface where the item to be hoisted is located to a horizontal state, thereby realizing the rapid hoisting of the item. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0054] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0056] Please refer to the following: Figures 1 to 13 The rapid hoisting device for sand and gravel mines provided in this application will now be described. The rapid hoisting device for sand and gravel mines proposed in this application includes a base 1, a support assembly 2, and multiple counterweights 3.

[0057] The base 1 is a cylindrical structure with a circular cross-section, used for fixing on the ground or other horizontal surfaces. The base 1 has multiple gravity sensors 10, which are spaced apart around the circumference of the base 1. In this embodiment, the base of the gravity sensor 10 is fixed to the upper side of the base 1, and the sensing end of the gravity sensor 10 is facing upward.

[0058] The base 1 has a balance plate 4 on its upper side, which is coaxially arranged with the upper side of the base 1. When the balance plate 4 is in a horizontal state, the lower side of the balance plate 4 is in contact with each gravity sensor 10. At this time, the values ​​of multiple gravity sensors 10 are equal, which is the sum of the weight of the balance plate 4 itself, the components on the balance plate 4, and the objects on the balance plate 4. In another case, that is, when the balance plate 4 is in a tilted state, the lower side of the balance plate 4 remains in contact with at least one gravity sensor 10. When two or more gravity sensors 10 have readings, the side corresponding to the gravity sensor 10 with the larger reading is the side of the balance plate 4 that is tilted downward. At this time, by applying pressure to the other side symmetrical to this side, the balance plate 4 can be restored to a horizontal state.

[0059] The support component 2 is used to support the item to be hoisted (hereinafter referred to as "item"). That is, the support component 2 has an upward support surface, and the item can be placed on this support surface. At this time, if the balance point of the item does not fall on the center of the support surface, the support component 2 will tilt.

[0060] The support component 2 is also used to connect with lifting equipment; specifically, a hoisting rope is fixedly installed above the support surface of the support component 2, and the hook of the lifting equipment can cooperate with the hoisting rope to realize the lifting and translating of the support component 2, thereby driving the object to move synchronously with the lifting and translating of the support component 2.

[0061] The support component 2 can be coaxially mounted on the upper side of the balance plate 4; coaxiality here means that the support surface of the support component 2 and the central axis of the upper side of the balance plate 4 coincide. When the support component 2 is coaxially mounted on the upper side of the balance plate 4, if the balance point of the object does not coincide with the center of the support surface of the support component 2, the support component 2 can tilt and drive the balance plate 4 to tilt synchronously, causing the readings of multiple gravity sensors 10 to change simultaneously.

[0062] Multiple counterweights 3 can be detachably mounted on the support assembly 2 and are spaced apart along the circumference of the base 1. In actual use, the weight on one side of the support assembly 2 can be increased or decreased by removing and installing the counterweights 3, thereby achieving a horizontal setting of the support surface of the support assembly 2.

[0063] It should be noted that in this embodiment, the number of counterweights 3 is equal to the number of gravity sensors 10, and multiple counterweights 3 correspond one-to-one with multiple gravity sensors 10; when the base 1 and the support assembly 2 are coaxially arranged, the corresponding counterweights 3 and gravity sensors 10 are arranged side by side in the vertical direction, so as to select the counterweight 3 on the other side according to the gravity sensor 10 with the larger reading.

[0064] In this embodiment, by placing the hoisted item on the support component 2 and placing the support component 2 on the upper side of the balance plate 4, it is possible to monitor whether the balance point of the item and the center of the support surface of the support component 2 coincide. When the balance point of the item and the center of the support surface of the support component 2 do not coincide, the support component 2 can drive the balance plate 4 to tilt, so that the corresponding gravity sensor 10 value changes.

[0065] Based on this, by adjusting the counterweight 3 on the other side, the balance plate 4 can be brought to a horizontal state, thereby quickly adjusting the support surface of the support component 2 to a horizontal state, so that the item to be hoisted moves with a horizontal plane, ensuring the stability of the item hoisting process.

[0066] The rapid hoisting device for sand and gravel mines provided in this embodiment, compared with the prior art, can quickly adjust the support surface where the item to be hoisted is located to a horizontal state, thereby realizing the rapid hoisting of the item.

[0067] In some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, the support assembly 2 includes a hanging platform 21 and a support platform 22.

[0068] The lifting platform 21 is used to connect with the lifting equipment to realize its lifting and translation; that is, the aforementioned lifting rope is set on the upper side of the lifting platform 21 to realize its cooperation with the hook of the lifting equipment.

[0069] The support platform 22 is located below the lifting platform 21, and the upper side of the support platform 22 is the aforementioned support surface, which is used to support the items to be lifted.

[0070] In order to realize the combination of support platform 22 and hanging platform 21, support platform 22 has multiple connecting rods 221 extending upward. The multiple connecting rods 221 are arranged at intervals along the circumference of support platform 22, and the upper end of each connecting rod 221 is connected to hanging platform 21.

[0071] In this embodiment, there are three connecting rods 221 to ensure that the spacing between adjacent connecting rods 221 is sufficient for the passage of items.

[0072] In some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, a limiting plate 5 is provided between the lifting platform 21 and the support platform 22; the limiting plate 5 is slidably connected to at least one connecting rod 221 in the vertical direction. In this embodiment, the limiting plate 5 is slidably connected to each connecting rod 221. Specifically, the limiting plate 5 has multiple through holes spaced apart along its circumference, and multiple connecting rods 221 are inserted into the multiple through holes one by one to realize the sliding connection relationship between the limiting plate 5 and each connecting rod 221.

[0073] The limiting plate 5 is connected to a linear drive component 6, which can drive the limiting plate 5 to move relative to the support platform 22. Furthermore, through its self-locking function, it can also provide a locking effect that prevents the limiting plate 5 from moving relative to the support platform 22.

[0074] The upper side of the support platform 22 has a groove 222 for inserting an item to be hoisted. Normally, one side of the item will be in contact with the inner side of the groove 222; ideally, the outer circumferential surface of the item will coincide with the inner circumferential surface of the groove 222. Based on this, the lower side of the limiting plate 5 has a boss 51, which can be inserted into the groove 222 as the limiting plate 5 descends to abut against the item in the groove 222 and restrict the movement of the item relative to the support platform 22.

[0075] By adopting the above technical solution, the linear drive component 6 can drive the limiting plate 5 to move downward until the boss 51 is embedded in the groove 222, and make the boss 51 abut against the item in the groove 222, so as to achieve the technical purpose of restricting the relative movement of the item and the support platform 22.

[0076] In some embodiments, such as Figure 4 , Figure 7 and Figure 9 As shown, the linear drive component 6 includes two swing arms 61 and a bidirectional screw 62.

[0077] Both swing arms 61 are hinged to the upper side of the limiting plate 5, and their hinge axes are parallel to each other. Specifically, the arrangement direction of the two swing arms 61 is defined as the left-right direction; correspondingly, the hinge axis of the swing arms 61 is the front-back direction. Each swing arm 61 has a hinge seat 7 hinged to its upper end along the front-back direction. The hinge seat 7 is slidably connected to the lifting platform 21 along the left-right direction, and each hinge seat 7 is fixedly provided with a transmission nut 721, the axis of which is parallel to the left-right direction.

[0078] The bidirectional screw 62 is rotatably mounted on the lifting platform 21, and both the axial direction and the rotational direction of the bidirectional screw 62 are parallel to the left and right directions.

[0079] The bidirectional screw 62 has two threaded portions with opposite thread directions; the two threaded portions are respectively threaded to two transmission nuts 721.

[0080] By adopting the above technical solution, when the aforementioned bidirectional screw 62 rotates, the two hinge seats 7 move towards each other or away from each other, thereby achieving the technical purpose of driving the limiting plate 5 to move relative to the platform 21 in the vertical direction through the swing arm 61.

[0081] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, two strip-shaped grooves 211 are formed on the upper side of the lifting platform 21. The two strip-shaped grooves 211 are arranged in the left-right direction, and each strip-shaped groove 211 extends in the left-right direction. Based on this, a guide hole 212 is formed at the bottom of each strip-shaped groove 211, and the guide hole 212 extends in the left-right direction. Furthermore, a baffle 213 can be detachably connected to the opening of each strip-shaped groove 211. The baffle 213 can block the opening of the strip-shaped groove 211 to prevent impurities from entering the strip-shaped groove 211, thereby achieving the technical purpose of protecting the internal components of the strip-shaped groove 211.

[0082] In this embodiment, the hinge seat 7 includes a connecting part 71 and a transmission part 72.

[0083] The connecting part 71 is slidably disposed on the lower side of the lifting platform 21, and has an insert shaft 711 extending upward and fitted into the guide hole 212.

[0084] The transmission part 72 is fixedly installed at the upper end of the insert shaft 711 and is located in the aforementioned strip groove 211.

[0085] The aforementioned swing arm 61 and connecting part 71 are hinged in the front-to-back direction, and the transmission nut 721 is fixedly mounted on the transmission part 72; specifically, the transmission part 72 has a through hole in the left-to-right direction, and the transmission nut 721 is fixedly embedded in the through hole.

[0086] A reserved groove 214 is provided on the outer wall of the lifting platform 21, which runs through the two strip grooves 211 in the direction of their arrangement (i.e., the left and right direction). The reserved groove 214 is connected to the two strip grooves 211. Based on this, the aforementioned bidirectional screw 62 is inserted into the reserved groove 214 to achieve threaded engagement with the two transmission nuts 721. One end of the bidirectional screw 62 is located outside the reserved groove 214 and is connected to a drive handle 621 to facilitate manual control of its movement.

[0087] In some embodiments, such as Figure 3 , Figure 5and Figure 6 As shown, the outer wall of the support platform 22 has a plurality of protrusions 223 spaced apart along its circumference; the counterweight 3 has a locking groove 31 on the side facing the support platform 22, and the locking groove 31 extends vertically to penetrate the lower end face of the counterweight 3 to accommodate the protrusions 223; specifically, by moving the counterweight 3 to abut against the outer side of the support platform 22, so that the lower end of the locking groove 31 faces the protrusion 223, and then moving the counterweight 3 downward, the protrusion 223 and the locking groove 31 can be engaged; since the cross-sections of the locking groove 31 and the protrusion 223 are both T-shaped, after the protrusion 223 and the locking groove 31 are engaged, the counterweight 3 cannot be disengaged from the support platform 22 without human intervention.

[0088] In some embodiments, such as Figure 3 and Figure 5 As shown, the counterweight 3 has a hollow internal structure, and its interior is used to contain the counterweight medium.

[0089] It should be noted that the counterweight medium here can be common stones found in sand and gravel mines, or it can be a fluid medium that is easier to input and output.

[0090] In some embodiments, such as Figure 1 , Figure 3 and Figure 11 As shown, the rapid hoisting device for sand and gravel mines also includes a water pump 8.

[0091] The inlet end of the water pump 8 is used to connect to an external water source, and the water pump 8 is fixedly installed on the outside of the base 1; the outlet end of the water pump 8 has a water delivery pipe 81, which is adapted to connect to any one of the counterweights 3 to achieve the technical purpose of filling the inside of the counterweight 3 with fluid.

[0092] Based on this, the base 1 includes a fixing part 11 and a rotating part 12.

[0093] The fixed part 11 is used to support the ground; the rotating part 12 is rotatably disposed on the upper side of the fixed part 11, and each gravity sensor 10 is disposed on the rotating part 12.

[0094] A rotating motor 9 is provided on the fixed part 11. The power output axis of the rotating motor 9 is parallel to the vertical direction, and the power output end of the rotating motor 9 is connected to the rotating part 12.

[0095] By adopting the above technical solution, the rotating part 12 can be driven to rotate by the rotating motor 9, so as to rotate the counterweight 3 to be adjusted to a position facing the water pump 8, so as to fill it with water.

[0096] In this embodiment, as Figures 11 to 13As shown, the upper side of the fixed part 11 is provided with a first square groove, and the lower side of the rotating part 12 is provided with a second square groove. After the fixed part 11 and the rotating part 12 are connected, the first square groove and the second square groove are connected. The rotating motor 9 is fixedly installed in the cavity formed by the interconnection, and its power output end is connected to the bottom of the second square groove to realize its driving effect on the rotating part 12. At the same time, the cross-section of the first square groove is larger than the cross-section of the rotating motor 9 to avoid interference with the rotation of the rotating part 12 when the rotating motor 9 is started due to contact between the body and the second square groove.

[0097] In some embodiments, such as Figure 3 , Figure 11 and Figure 12 As shown, the upper side of the base 1 has a plurality of receiving slots 121 arranged at intervals along its circumference; the aforementioned plurality of gravity sensors 10 are embedded in the plurality of receiving slots 121 one by one, and the sensing end of each gravity sensor 10 extends to the upper side of the base 1.

[0098] In this embodiment, the sensing end of the gravity sensor 10 is connected to a spherical component, and the spherical component extends to the upper side of the base 1.

[0099] In some embodiments, such as Figure 3 , Figure 10 and Figure 12 As shown, the center of the upper side of the base 1 has a concave ball groove 122, and the lower side of the balance plate 4 is provided with a convex shaft 41 that is inserted into the concave ball groove 122, and the end of the convex shaft 41 is connected to the bottom of the concave ball groove 122.

[0100] It should be noted that, in order to enhance the fit between the convex shaft 41 and the bottom of the concave ball groove 122, a structure similar to a ball joint support can be provided between the lower end of the convex shaft 41 and the center of the concave ball groove 122 to prevent the convex shaft 41 from detaching from the concave ball groove 122 and the balance plate 4 from detaching from the base 1.

[0101] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
