[0031] See Figures 1 to 4 As shown, this utility model provides a specific embodiment of a construction workpiece hoisting device, including: a movable frame 10, a connecting mechanism 20, and a hoisting frame 30; at least two sets of connecting mechanisms 20 are connected to the top of the movable frame 10 and to the bottom of the hoisting frame 30; the connecting mechanism 20 includes two connecting rods 201; the tops of the two connecting rods 201 are rotatably connected to the hoisting frame 30, and the bottoms are movably connected to the movable frame 10; when the bottoms of the two connecting rods 201 move towards each other on the movable frame 10, the tops of the connecting rods 201 drive the hoisting frame 30 to rise; when the bottoms of the two connecting rods 201 move away from each other on the movable frame 10, the tops of the connecting rods 201 drive the hoisting frame 30 to fall.

[0032] Specifically, the design principle of this embodiment lies in achieving height adjustment through the combined structure of the movable frame 10, the connecting mechanism 20, and the hoisting frame 30. The connecting mechanism 20 adopts at least two symmetrically arranged structures, each containing two connecting rods 201. The top of the connecting rod 201 is rotatably connected to the hoisting frame 30, and the bottom is movably connected to the movable frame 10, forming a movable support structure. When the bottoms of the two connecting rods 201 move towards each other on the movable frame 10, the isosceles structure formed by the connection points of the connecting rods 201, the movable frame 10, and the hoisting frame 30 changes, and the tilt angle of the connecting rods 201 increases, thereby pushing the hoisting frame 30 upward. Conversely, when the bottoms of the two connecting rods 201 move away from each other, the tilt angle of the connecting rods 201 decreases, and the hoisting frame 30 lowers accordingly. The height adjustment function is achieved through the linkage of the mechanical structure.

[0033] This embodiment adopts a purely mechanical linkage method with connecting rod 201. The stability of the hoisting frame 30 during the lifting process is ensured by setting at least two sets of connecting mechanisms 20, avoiding swaying of the workpiece during hoisting and improving the safety of hoisting operations. At the same time, the hoisting height can be flexibly adjusted by moving the bottom of the connecting rod 201, which is convenient to operate and suitable for workpiece hoisting needs under various construction conditions.

[0034] In one specific embodiment, the top of the movable frame 10 is provided with a first slide rail (not shown in the figure), and the bottom of the connecting rod 201 is rotatably connected to a first slider 202, which is slidably connected to the first slide rail.

[0035] Specifically, in this embodiment, the sliding connection between the first slide rail and the first slider 202 provides guidance for the movement of the bottom of the connecting rod 201, ensuring that the bottoms of the two connecting rods 201 can move precisely towards or away from each other along a preset trajectory, avoiding deviation during movement and further improving the stability and reliability of the lifting frame 30. At the same time, the sliding connection reduces the frictional resistance when the bottom of the connecting rod 201 moves, making operation more labor-saving and improving the efficiency of lifting operations. Furthermore, the simple structure of the slide rail and slider facilitates mass production and assembly.

[0036] In one specific embodiment, the movable frame 10 includes a support assembly 101, two parallel first crossbars 102 and two parallel second crossbars 103. The two first crossbars 102 and the two second crossbars 103 are connected to form a rectangular frame 10a. The support assembly 101 is connected to the bottom of the rectangular frame 10a, and a first slide rail is provided along the first crossbars 102.

[0037] Specifically, the design principle of this embodiment is to refine the structure of the mobile frame 10, using a support component 101, two first crossbars 102, and two second crossbars 103 to form the main body of the mobile frame 10. The two first crossbars 102 and the two second crossbars 103 are connected to form a rectangular frame 10a. This frame structure provides a stable support foundation and also provides a carrier for the installation of the first slide rail, allowing the first slide rail to be precisely set along the length of the first crossbar 102. The support component 101 is connected to the bottom of the rectangular frame 10a, serving to support the entire mobile frame 10 and its upper structure. The combination of the rigid structure of the rectangular frame 10a and the supporting function of the support component 101 ensures the structural strength of the mobile frame 10 when bearing the lifting weight.

[0038] In one specific embodiment, the support assembly 101 includes at least two first support rods 1011 and at least two second support rods 1012. The at least two first support rods 1011 are all connected to the same side of the rectangular frame 10a and are arranged vertically, and the at least two second support rods 1012 are all connected to the other side of the rectangular frame 10a and are arranged vertically.

[0039] Specifically, the design principle of this embodiment is to optimize the structure of the support component 101. At least two first support rods 1011 and at least two second support rods 1012 are respectively connected to both sides of the rectangular frame 10a and are vertically arranged. The support rods on both sides are symmetrically distributed, forming balanced support for the rectangular frame 10a. Through the synergistic effect of multiple support rods, the weight of the rectangular frame 10a and the upper structure is evenly transferred to the lower support surface. This multi-support rod arrangement enhances the stability of the support component 101, avoiding tilting or damage caused by excessive force on a single support rod, and ensuring the structural stability of the mobile frame 10 during hoisting operations. For the case where the first support rod 1011 is supported by the walkway 40 and the second support rod 1012 is supported by the I-shaped track 50, the two types of support rods can adapt to the load-bearing requirements of different support surfaces. The symmetrically distributed structure can balance the force on the two types of support surfaces, ensuring the stability of the device in mixed support scenarios.

[0040] In one specific embodiment, the first support rod 1011 and / or the second support rod 1012 are telescopic rods.

[0041] Specifically, in this embodiment, the first support rod 1011 and / or the second support rod 1012 are configured as telescopic rods, enabling the device to flexibly adapt to different working height requirements without the need for additional shims, thus simplifying pre-operation preparation. In cases where the support surface is uneven, the horizontal alignment of the mobile frame 10 can be achieved by adjusting the telescopic length of the first support rod 1011 and / or the second support rod 1012, ensuring the accuracy of the hoisting operation. Furthermore, the retracted telescopic rods reduce the overall volume of the device, facilitating storage and transportation and enhancing its practicality. Moreover, regarding the height difference between the walkway 40 and the I-beam track 50, height compensation can be directly achieved by adjusting the telescopic length of the first support rod 1011 and / or the second support rod 1012, allowing for device leveling without complex operations and significantly improving operational efficiency and safety in mixed support scenarios.

[0042] In one specific embodiment, the bottom of both the first support rod 1011 and the second support rod 1012 are connected to a pulley assembly 104. The pulley assembly 104 includes a first connector 1041 and a first pulley 1042. The first connector 1041 is connected to the bottom of the first support rod 1011 or the second support rod 1012. The first pulley 1042 is rotatably connected to the first connector 1041 and is vertically arranged for sliding on the support surface.

[0043] Specifically, this embodiment, through the installation of the pulley assembly 104, enables the device to move flexibly on the support surface, allowing for changes in the hoisting position without manual handling, significantly reducing labor intensity and improving work efficiency. Furthermore, the pulley assembly 104 has a simple structure, is easy to maintain, and exhibits less wear from rolling friction compared to sliding friction, extending the device's service life. In the scenario where the first support rod 1011 corresponds to the walkway 40 and the second support rod 1012 corresponds to the I-shaped track 50, the first pulley 1042 can contact the surface of the walkway 40 or the top surface of the I-shaped track 50 respectively. By replacing traditional sliding friction with the rolling motion of the pulley, the resistance when the device moves on the two types of support surfaces is reduced, allowing the device to move conveniently along the extension direction of the walkway 40 and the I-shaped track 50. Combined with the adaptation of the first support rod 1011 and the second support rod 1012 to the height difference, hoisting operations across support surfaces are achieved.

[0044] In one specific embodiment, a clamping assembly 105 is connected below the second support rod 1012. The clamping assembly 105 is used to clamp both sides of the I-shaped track 50 and slide relative to the I-shaped track 50.

[0045] Specifically, this embodiment is designed for the second support rod 1012 corresponding to the support surface of the I-shaped track 50. A clamping assembly 105 is connected below the second support rod 1012. The clamping assembly 105 can clamp both sides of the I-shaped track 50 and can slide relative to the I-shaped track 50. The connection between the clamping assembly 105 and the second support rod 1012 restricts the horizontal displacement of the device when it moves on the I-shaped track 50 through the clamping action. Combined with the support of the first support rod 1011 on the walkway 40 and the height adaptation of the telescopic rod, it ensures that the device always moves in the preset direction during the movement across the walkway 40 and the I-shaped track 50. This is especially suitable for mixed support surface operation scenarios with high stability requirements, such as high-altitude operations.

[0046] This embodiment effectively prevents the device from tipping over or deviating due to external forces or unevenness of the track when moving on the I-shaped track 50, thanks to the clamping action of the clamping component 105. Combined with the telescopic rod's adaptation to the height difference between the walkway 40 and the I-shaped track 50, it significantly improves the safety of high-altitude mixed support surface hoisting operations. The sliding engagement between the clamping component 105 and the track does not affect the normal movement of the device, ensuring both stability and ease of movement. Furthermore, the clamping component 105 allows the device to move more precisely along the I-shaped track 50 to the target position, improving the accuracy of the hoisting operation.

[0047] In one specific embodiment, the clamping assembly 105 includes a second connector 1051 and a slider 1052; both second connectors 1051 are connected to the bottom of the second support rod 1012 and are located on both sides of the second support rod 1012 respectively; the inner sides of both second connectors 1051 are equipped with sliders 1052 below the second support rod 1012, and the sliders 1052 on both sides are used to clamp the two sides of the I-shaped track 50 and slide relative to the I-shaped track 50.

[0048] Specifically, in this embodiment, the symmetrical structure of the two second connecting pieces 1051 enables the clamping assembly 105 to exert a balanced clamping force on the I-shaped track 50, avoiding device tilting caused by unilateral force. Combined with the leveled foundation after the telescopic rod is used, this further enhances the stability during the movement of the hybrid support surface. The sliding member 1052, while fulfilling the clamping function, ensures smooth movement of the device and does not hinder position adjustment due to the clamping action. Furthermore, the modular structural design facilitates the replacement and maintenance of the sliding member 1052, reducing operating costs.

[0049] In one specific embodiment, the slider 1052 is a second pulley, which is horizontally arranged and rotatably connected to the second connector 1051.

[0050] Specifically, in this embodiment, the horizontally positioned second pulley effectively reduces the friction between the clamping assembly 105 and the I-shaped track 50. Combined with the first pulley 1042 at the bottom of the first support rod 1011, the device moves more effortlessly and conveniently on the mixed support surface formed by the walkway 40 and the I-shaped track 50, improving work efficiency. Rolling friction causes less wear than sliding friction, extending the service life of the clamping assembly 105, track, and pulley assembly 104. Furthermore, the rotation of the second pulley can adapt to minor unevenness on the track surface, and together with the horizontal state maintained by the telescopic rod, ensures the stability of the device during movement, further enhancing the safety of hoisting operations.

[0051] In one specific embodiment, the second connector 1051 is L-shaped and includes a base plate 10511 vertically disposed on one side of the support rod and a mounting plate 10512 horizontally connected to the inner side of the base plate 10511. The second pulley is rotatably connected to the mounting plate 10512.

[0052] Specifically, this embodiment utilizes the compact structure of the L-shaped second connector 1051, effectively saving installation space and ensuring a more secure connection between the clamping assembly 105 and the second support rod 1012 without interfering with the telescopic adjustment operation of the telescopic rod. The vertical connection between the base plate 10511 and the side of the second support rod 1012 enhances the load-bearing capacity of the second connector 1051, preventing deformation of the second connector 1051 during clamping. The horizontal arrangement of the mounting plate 10512 ensures that the installation height of the second pulley matches the side of the I-shaped track 50, ensuring effective clamping. Furthermore, the L-shaped second connector 1051 has a simple manufacturing process, facilitating mass production and reducing manufacturing costs.

[0053] It is understandable that the two second connecting parts 1051 can be installed independently or as a single unit. Both installation methods provide flexibility for the production and assembly of the device, allowing for the selection of the appropriate method based on different production processes and usage requirements. The preferred option of a single unit enhances the overall structural strength of the clamping assembly 105, resulting in a more balanced and stable clamping force, and reduces assembly errors.

[0054] In one specific embodiment, a balance bar 106 is connected at the bottom between two adjacent first support rods 1011 and between two adjacent second support rods 1012, and the support rods are arranged parallel to the second crossbar 103.

[0055] Specifically, this embodiment significantly improves the overall stability and deformation resistance of the movable frame 10 by adding the balance bar 106, enabling the support bars on the same side to work together to bear the load, reducing the load-bearing pressure on individual support bars, and extending the service life of the support bars and telescopic bars. The connection between the balance bar 106 and the support bars forms a more stable bottom support structure. Combined with the leveling effect of the telescopic bars, even when there is a large height difference between the walkway 40 and the I-shaped track 50 or the hoisting load is uneven, the overall level of the movable frame 10 can be guaranteed, preventing the device from tilting. In addition, the setting of the balance bar 106 provides an attachment point for the subsequent installation of other functional components, enhancing the functional expandability of the device.

[0056] In one specific embodiment, a reinforcing rod 107 is connected between two adjacent second support rods 1012, and the reinforcing rod 107 is inclined.

[0057] Specifically, this embodiment significantly improves the connection strength and overall stability between the second support rods 1012 by setting the reinforcing rod 107. The triangular support structure makes the group of second support rods 1012 form a more stable whole, which can resist the impact of external forces generated during hoisting. Combined with the adjustment function of the telescopic rod, it ensures that the structure remains stable when adapting to the height of the I-shaped track 50. The tilt angle of the reinforcing rod 107 can be designed according to the actual force requirements to further optimize the force distribution effect. At the same time, the structure of the reinforcing rod 107 is simple, requiring no complex connecting parts, and has a low cost. In addition, the setting of this structure enables the moving frame 10 to maintain structural stability when carrying heavy workpieces, expanding the applicability of the device.

[0058] In one specific embodiment, the bottom of the hoisting frame 30 is provided with a second slide rail (not shown in the figure), the second slide rail is arranged parallel to the second crossbar 103 and is slidably connected to a second slider (not shown in the figure), the connecting rod 201 is rotatably connected to the second slider, and the second crossbar 103, the balance bar 106 and the reinforcing bar 107 are all telescopic rods.

[0059] Specifically, this embodiment achieves flexible lateral adjustment of the support component 101 and the connecting mechanism 20 through the coordinated action of the second slide rail, the second slider, and the telescopic rod, precisely solving the hoisting challenges in different spatial scenarios. When a narrow space cannot accommodate the entire device, only lateral retraction adjustment is needed to extend part of the hoisting frame 30 into the work area without moving the entire device, significantly reducing the impact of space limitations on operations and improving the feasibility of working in narrow environments. When the hoisting points are located at both ends of the hoisting frame 30, lateral adjustment moves the support component 101 and the connecting mechanism 20 towards the center, effectively avoiding obstacles to the hoisting operation and ensuring a smooth hoisting process. At the same time, the cooperation of the second slide rail and the second slider ensures the stability of the top movement of the connecting rod 201, while the telescopic rods ensure the structural strength of the support component 101 after adjustment. While achieving flexible adjustment of the hoisting position, it also takes into account the safety and stability of the operation, significantly enhancing the device's adaptability to complex spatial environments.

[0060] It is understood that the telescopic pole in this application can adopt various solutions such as manual telescopic pole, electric telescopic pole and hydraulic telescopic pole, and is preferably an electric telescopic pole.

[0061] In one specific embodiment, a third crossbar 108 is connected between the first support rod 1011 and the second support rod 1012. The third crossbar 108 is arranged parallel to the first crossbar 102 and is located below the first crossbar 102. A first connecting rod 109 is provided between the first crossbar 102 and the third crossbar 108. Both ends of the first connecting rod 109 are rotatably connected to third sliders 110, and the two third sliders 110 are slidably connected to the first crossbar 102 and the third crossbar 108, respectively.

[0062] Specifically, for the scenario where the first support rod 1011 and the second support rod 1012, as telescopic rods, need to adapt to the height difference between the walkway 40 and the I-shaped track 50, when the two types of support rods are telescopically adjusted, the third crossbar 108 moves up and down with the change in the length of the support rods. At this time, the third sliders 110 at both ends of the first connecting rod 109 slide along the first crossbar 102 and the third crossbar 108. The angle change of the first connecting rod 109 adapts to the change in the distance between the two crossbars. At the same time, the first connecting rod 109 can form an oblique support for the two crossbars, enhance the connection rigidity between them, and prevent the moving frame 10 from shaking during the telescopic process of the support rods.

[0063] This embodiment, through the cooperative structure of the third crossbar 108 and the first connecting rod 109, achieves the telescopic adjustment of the support rod to adapt to the height difference of the support surface while ensuring the structural stability of the movable frame 10 and avoiding a decrease in the rigidity of the device during the telescopic rod adjustment process. The sliding connection between the third slider 110 and the crossbar allows the first connecting rod 109 to flexibly adapt to different telescopic heights without affecting the adjustment function of the support rod. At the same time, the oblique support effectively disperses the load and improves the load-bearing capacity of the movable frame 10. In addition, the design of this structure makes the height adjustment of the movable frame 10 more stable, further enhancing the adaptability of the device to mixed support scenarios of the walkway 40 and the I-shaped track 50.

[0064] In one specific embodiment, a fourth slider 111 is slidably connected below the second crossbar 103, and a second connecting rod 112 is rotatably connected to the fourth slider 111. The end of the second connecting rod 112 away from the fourth slider 111 is rotatably connected to the second support rod 1012.

[0065] Specifically, in this embodiment, the fourth slider 111 and the second connecting rod 112 provide additional support points for the second support rod 1012, enhancing the stability of the second support rod 1012 during telescopic adjustment and preventing it from shifting due to unilateral force. Combined with the telescopic adjustment of the first support rod 1011, this ensures the horizontal state of the moving frame 10 under the height difference between the walkway 40 and the I-beam track 50. This structure, working in conjunction with the first connecting rod 109, makes the force on the moving frame 10 more balanced during height adjustment, improving the overall rigidity of the device and enabling it to withstand greater lifting loads. Simultaneously, the sliding and rotating connection makes the telescopic adjustment of the support rod smoother, reducing the risk of mechanical jamming.

[0066] It is understood that in this embodiment and other embodiments, after the first slider 202, the second slider, the third slider 110 and the fourth slider 111 slide into place, they can be fixed by bolts or other fixing connectors, so that the device can maintain a stable working posture after completing the longitudinal and lateral adjustments. This avoids problems such as the part of the hoisting frame 30 leaving the target area, horizontal imbalance or hoisting operation being obstructed due to component displacement during the hoisting process, and significantly improves the safety and reliability of complex space operations.

[0067] In one specific embodiment, the hoisting frame 30 includes a fixed rod 301, a wire rope 302, and a hoist 303. The fixed rod 301 is horizontally arranged. Several hoists 303 are connected to the fixed rod 301 through the wire rope 302, and a second slide rail is provided at the bottom of the fixed rod 301.

[0068] Specifically, the horizontally positioned fixed rod 301 provides a stable installation foundation for the hoists 303 and the second slide rail. Several hoists 303 are connected to the fixed rod 301 by wire ropes 302. The flexibility of the wire ropes 302 can flexibly adapt to different hoisting angles and can buffer the impact force during hoisting, reducing rigid collision damage between the workpiece and the device. The number and hoisting position of the hoists 303 can also be adjusted as needed, thereby achieving flexible and stable hoisting operations and adapting to various construction workpiece hoisting scenarios.

[0069] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
