Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and more specifically to a support device used for hoisting. Background Technology

[0002] In fields such as industrial production, construction, and equipment installation, where hoisting operations are widely involved, tripod supports serve as a fundamental and crucial support tool with extremely common applications. However, due to the fixed opening and closing distance of its three support legs, when hoisting small items, excessively large leg spacing can cause the tripod support's center of gravity to shift, significantly reducing stability and making it prone to swaying or even tipping over under external forces. Conversely, when hoisting large items, insufficient leg spacing restricts operating space and increases the risk of collisions between the items and the support legs. Furthermore, if subjected to significant external forces during hoisting, adjacent support legs are prone to relative displacement, leading to overall structural deformation. This significantly reduces the safety and stability of hoisting operations, limiting the application range of tripod supports in complex working conditions. Utility Model Content

[0003] In view of this, the present invention provides a support device for hoisting, so as to solve the problems that traditional triangular support frames cannot adapt to hoisting items of different sizes and have poor stability.

[0004] This utility model provides a support device for hoisting, including a hoisting plate, three support legs, and three telescopic rods; the bottom of the hoisting plate is adapted to install a hoisting mechanism; the three support legs are arranged sequentially at intervals around the hoisting mechanism; and each support leg is rotatably connected to the bottom of the hoisting plate, having a rotating position relative to the hoisting plate and a fixed position fixed to the hoisting plate; a telescopic rod is provided between every two adjacent support legs, and the two ends of the telescopic rod are respectively rotatably connected to the two adjacent support legs; when the support leg is in the rotating position, the telescopic rod is in a telescopic state; when the support leg is in the fixed position, the telescopic rod is in a fixed state.

[0005] Beneficial effects: Because the three support legs are rotatably connected and installed at the bottom of the lifting platform, when it is necessary to adapt to lifting items of different sizes, the opening and closing distance between two adjacent support legs can be changed by rotating the support legs. This allows the support device to be flexibly adjusted according to the actual size of the item, avoiding problems such as instability due to excessive spacing and difficulty in moving items due to insufficient spacing. Furthermore, when the support legs are in the rotating position, the telescopic rod is in the telescopic state, which can adjust its length in real time according to the opening and closing angle of the support legs, ensuring the smoothness of the adjustment process. When the support legs are rotated to the target position, the telescopic rod is simultaneously locked to a fixed length. At this time, the relative position between the support legs and the lifting platform is also locked. This linkage design gives the telescopic rod both adaptive adjustment and rigid support characteristics. It can automatically adapt its length according to the change of the support leg spacing, and can also provide stable support force in the fixed state, thus maintaining the balance and reliability of the device at any opening and closing angle. Therefore, through the setting of support legs and telescopic rod, it can not only adapt to lifting items of different sizes, but also ensure the structural stability during the lifting process, achieving a comprehensive improvement in stability, adaptability and ease of operation.

[0006] In one alternative implementation, the support leg is a telescopic leg.

[0007] Beneficial effects: By setting the support legs as telescopic legs, operators can flexibly extend or retract the support legs according to the actual situation when facing different usage scenarios or needs at different heights. This allows for precise adjustment of the overall length of the support legs, enabling them to adapt to various height requirements. Consequently, the device can function stably and reliably in different height environments. Furthermore, it is suitable for uneven placement environments. The length of each support leg can be adjusted according to the undulations of the ground to keep the suspended platform in a horizontal position. This not only improves the adaptability and flexibility of the device but also greatly enhances its effectiveness and safety in various complex environments.

[0008] In one optional embodiment, the support leg includes a first connecting leg, a second connecting leg, and a first fastener; one end of the first connecting leg is connected to the hanging plate, and the other end is provided with a plurality of first connecting holes spaced apart along its length; the second connecting leg is provided with a plurality of second connecting holes spaced apart along its length; the first fastener is detachably connected to different first connecting holes and second connecting holes.

[0009] Beneficial effects: By setting a first fastener, a detachable connection method is used to connect the first connecting holes at multiple different positions on the first connecting leg with the second connecting holes on the second connecting leg. When it is necessary to adjust the relative length between the first and second connecting legs, simply loosen the first fastener, select the appropriate matching first and second connecting holes, and then tighten the first fastener again to complete the length adjustment, meet different usage requirements, and realize the telescopic connection function between the first and second connecting legs.

[0010] In one optional embodiment, the first connecting leg is provided with a sliding groove, the second connecting leg extends into the sliding groove and slides in connection with the first connecting leg, and the first connecting hole is provided on the groove wall.

[0011] Beneficial effects: In applications where the supporting legs play their supporting role, they are usually set in an inclined state to adapt to actual support requirements. By setting a groove inside the first connecting leg and then extending the second connecting leg into the groove, the second connecting leg can automatically adjust to the optimal support position within the groove according to the actual inclination angle and force of the supporting leg. Through the tight fit with the groove wall and the interaction between them, the forces from all directions are effectively dispersed and borne, thereby significantly enhancing the stability of the connection between the first and second connecting legs and ensuring that the entire support structure can still play a stable and reliable supporting role in an inclined state.

[0012] In one alternative embodiment, the end of the support leg facing away from the suspended platform is provided with a ground-entry cone.

[0013] Beneficial effects: By setting a ground-entry cone at the end of the support leg away from the lifting plate, the ground-entry cone at the end of the support leg can be inserted into the ground to a certain depth. Through physical interlocking, the ground-entry cone forms a tight bond with the surrounding soil, thus providing a stable and reliable support foundation for the entire device. This not only enhances the adaptability of the device on uneven ground such as mountains, but also significantly improves its load-bearing capacity and wind and overturning resistance, ensuring the smooth progress of small heavy object lifting and hoisting operations.

[0014] In one alternative embodiment, the support leg is provided with a baffle, which is located on the side of the ground entry cone near the hanging plate and protrudes from the outer surface of the support leg.

[0015] Beneficial effects: By setting the baffle on the side of the ground entry cone close to the hanging plate, the baffle can limit the insertion of the support leg into the ground when it is inserted, effectively preventing the support leg from being inserted too deeply into the ground due to continued downward pressure, and ensuring that the support leg maintains the appropriate insertion depth during use.

[0016] In one alternative embodiment, the telescopic rod is fixed to the side of the support leg near the suspended platform.

[0017] Beneficial effects: By setting the telescopic rod on the side of the support leg closer to the hanging plate, the interaction between the support device and the ground environment is fully considered, effectively avoiding the risk of interference with possible obstacles on the ground, thus ensuring that the support device can be placed smoothly and without obstruction.

[0018] In one optional embodiment, the telescopic rod includes: a first connecting rod, a second connecting rod, and a second fastener; one end of the first connecting rod is connected to the support leg, and the other end is provided with a plurality of third connecting holes spaced apart along its length; one end of the second connecting rod is connected to an adjacent support leg, and the other end is provided with a plurality of fourth connecting holes spaced apart along its length; the second fastener is detachably connected to different third connecting holes and fourth connecting holes.

[0019] Beneficial effects: By setting a second fastener, the third connecting holes at multiple different positions on the first connecting rod are connected to the fourth connecting hole on the second connecting rod in a detachable manner. When it is necessary to adjust the relative length between the first and second connecting rods, simply loosen the second fastener, select the appropriate and matching third and fourth connecting holes, and then tighten the second fastener again to complete the length adjustment, meet different usage requirements, and realize the telescopic connection function between the first and second connecting rods.

[0020] In one alternative embodiment, the lifting plate is provided with a hanging hole, which is suitable for installing a lifting mechanism.

[0021] Beneficial effects: By setting up hanging holes, it is easier to smoothly install and fix the hoisting mechanism.

[0022] In one optional embodiment, three bases are provided below the hanging platform, and the three bases correspond one-to-one with the three supporting legs, and the supporting legs are hinged to the corresponding bases.

[0023] Beneficial effects: By setting a base under the hanging platform and hinged the support legs to the base, the support legs can be flexibly rotated and adjusted relative to the hanging platform with the base as the center of rotation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined Figs. 1-2 The following describes embodiments of the present invention.

[0031] According to an embodiment of this utility model, a support device for hoisting is provided, including a hoisting plate 1, three support legs 2, and three telescopic rods 3; the bottom of the hoisting plate 1 is adapted to install a hoisting mechanism; the three support legs 2 are arranged sequentially at intervals around the hoisting mechanism; and the support legs 2 are rotatably connected to the bottom of the hoisting plate 1, having a rotational position relative to the hoisting plate 1 and a fixed position fixed to the hoisting plate 1; a telescopic rod 3 is provided between every two adjacent support legs 2, and the two ends of the telescopic rod 3 are respectively rotatably connected to the two adjacent support legs 2; when the support leg 2 is in the rotational position, the telescopic rod 3 is in a telescopic state; when the support leg 2 is in the fixed position, the telescopic rod 3 is in a fixed state.

[0032] Because the three support legs 2 are rotatably connected and installed at the bottom of the lifting platform 1, when it is necessary to accommodate lifting items of different sizes, the opening and closing distance between two adjacent support legs 2 can be changed by rotating the support legs 2. This allows the support device to be flexibly adjusted according to the actual size of the item, avoiding problems such as instability due to excessive spacing and insufficient spacing affecting the space for items to enter and exit. Furthermore, since the telescopic rod 3 is in the telescopic state when the support legs 2 are in the rotating position, it can adjust its own length in real time according to the opening and closing angle of the support legs 2, ensuring the smoothness of the adjustment process. When the support legs 2 are rotated to the target position... At the same time, the telescopic rod 3 is locked to a fixed length, and the relative position of the support leg 2 and the lifting plate 1 is also locked. This linkage design gives the telescopic rod 3 both adaptive adjustment and rigid support characteristics. It can automatically adapt to the length according to the change of the support leg 2 spacing, and can provide stable support force in the fixed state. Thus, the balance and reliability of the device can be maintained at any opening and closing angle. Therefore, by setting up the support leg 2 and the telescopic rod 3, it can not only adapt to the lifting of different sizes of lifting objects, but also ensure the structural stability during the lifting process, and achieve a comprehensive improvement in stability, adaptability and ease of operation.

[0033] In a specific implementation, the hanging platform 1 is made of high-strength steel.

[0034] Preferably, the hoisting mechanism is installed at the center of the hoisting plate 1.

[0035] In one embodiment, the support leg 2 is a telescopic leg.

[0036] By setting the support leg 2 as a telescopic leg, when faced with different usage scenarios or needs at different heights, the operator can flexibly extend or retract the support leg 2 according to the actual situation, thereby precisely adjusting the overall length of the support leg 2 to adapt to various different height requirements. This ensures that the device can function stably and reliably in different height environments. Furthermore, it is suitable for uneven placement environments. The length of each support leg 2 can be adjusted according to the undulations of the ground to keep the hanging plate 1 in a horizontal position. This not only improves the adaptability and flexibility of the device, but also greatly enhances its performance and safety in various complex environments.

[0037] In one embodiment, the support leg 2 includes a first connecting leg 21, a second connecting leg 22, and a first fastener 23; one end of the first connecting leg 21 is connected to the hanging plate 1, and the other end is provided with a plurality of first connecting holes spaced apart along its length; the second connecting leg 22 is provided with a plurality of second connecting holes spaced apart along its length; the first fastener 23 can be detachably connected to different first connecting holes and second connecting holes.

When it is necessary to adjust the relative length between the first connecting leg 21 and the second connecting leg 22, simply loosen the first fastener 23, select the appropriate and matching first and second connecting holes, and then tighten the first fastener 23 again to complete the length adjustment, meet different usage requirements, and realize the telescopic connection function between the first connecting leg 21 and the second connecting leg 22.

[0040] In applications where the support leg 2 performs its supporting function, it is usually set in an inclined state to meet actual support requirements. By setting a groove inside the first connecting leg 21 and then extending the second connecting leg 22 into the groove, the second connecting leg 22 can automatically adjust to the optimal support position in the groove according to the actual inclination angle and force of the support leg 2. Through the close fit with the groove wall and the interaction between them, the force from all directions is effectively dispersed and borne, thereby significantly enhancing the stability of the connection between the first connecting leg 21 and the second connecting leg 22, ensuring that the entire support structure can still perform its supporting function stably and reliably in an inclined state.

[0041] In one embodiment, the end of the support leg 2 facing away from the hanging plate 1 is provided with a ground-entry cone 24.

[0042] By setting a ground-entry cone 24 at the end of the support leg 2 away from the lifting plate 1, the ground-entry cone 24 at the end of the support leg 2 can be inserted into the ground to a certain depth. Through physical interlocking, the ground-entry cone 24 forms a tight bond with the surrounding soil, thus providing a stable and reliable support foundation for the entire device. This not only enhances the adaptability of the device on uneven ground such as mountains, but also significantly improves its load-bearing capacity and wind and overturning resistance, ensuring the smooth progress of small heavy object lifting and hoisting operations.

[0043] In one embodiment, the support leg 2 is provided with a baffle 25, which is located on the side of the ground cone 24 near the hanging plate 1 and protrudes from the outer surface of the support leg 2.

[0044] By setting the baffle 25 on the side of the ground entry cone 24 close to the hanging plate 1, the baffle 25 can play a limiting role when the support leg 2 is inserted into the ground, effectively preventing the support leg 2 from being inserted too deeply into the ground due to continued downward pressure, and ensuring that the support leg 2 maintains an appropriate insertion depth during use.

[0045] In one embodiment, the telescopic rod 3 is fixed to the side of the support leg 2 near the hanging plate 1.

[0046] By setting the telescopic rod 3 on the side of the support leg 2 close to the hanging plate 1, the interaction between the support device and the ground environment is fully considered, effectively avoiding the risk of interference with possible obstacles on the ground, thereby ensuring that the support device can be placed smoothly and without obstruction.

[0047] In one embodiment, the telescopic rod 3 includes: a first connecting rod, a second connecting rod, and a second fastener; one end of the first connecting rod is connected to the support leg 2, and the other end is provided with a plurality of third connecting holes spaced apart along its length; one end of the second connecting rod is connected to the adjacent support leg 2, and the other end is provided with a plurality of fourth connecting holes spaced apart along its length; the second fastener is detachably connected to different third connecting holes and fourth connecting holes.

[0048] By setting a second fastener, a detachable connection method is used to connect the third connecting holes at multiple different positions on the first connecting rod with the fourth connecting hole on the second connecting rod. When it is necessary to adjust the relative length between the first and second connecting rods, simply loosen the second fastener, select the appropriate matching third and fourth connecting holes, and then tighten the second fastener again to complete the length adjustment, meet different usage requirements, and realize the telescopic connection function between the first and second connecting rods.

[0049] In one embodiment, the lifting plate 1 is provided with a hanging hole 11, which is suitable for installing a lifting mechanism.

[0050] The installation and fixation of the hoisting mechanism can be facilitated by setting the hanging hole 11.

[0051] In a specific implementation, the lifting mechanism can be a small hoist-type lifter.

[0052] Specifically, the support device used for hoisting, in conjunction with a small hoist-type lifting device, can lift objects weighing up to 200 kg, such as photovoltaic inverters, small motors, and reactors.

[0053] In one embodiment, three bases 12 are provided below the hanging plate 1, and the three bases 12 correspond one-to-one with the three supporting legs 2, and the supporting legs 2 are hinged to the corresponding bases 12.
