Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a lifting and wall-mounted mobile suspension device. Background Technology

[0002] In fields such as building construction, decoration and renovation, and equipment installation across walls, it is often necessary to carry out hanging operations on the outside of walls or across wall areas, such as hoisting exterior wall decorative panels, building temporary maintenance platforms, and transferring small equipment. Wall-mounted hanging devices are key equipment for achieving such operations.

[0003] In the prior art, such as the Chinese patent with authorization announcement number CN218912198U, a height-adjustable suspended platform suspension system is disclosed. Although this system solves the problem of insufficient erection height of traditional suspended platforms by using height-adjustable columns and avoids the risk of leakage caused by opening holes in parapet walls by using adjustable wall-mounted frames, thus improving applicability to a certain extent, it still has the following shortcomings in actual use: First, the system relies on columns and counterweights for fixed installation and does not have the ability to move. When the work point is moved, it needs to be disassembled and reassembled, which is cumbersome and inefficient, and cannot adapt to multi-point continuous operation scenarios. Second, the adjustment dimensions are limited, and it can only adjust the height of the columns and the length of the suspension beam. It cannot adjust the angle of the support arm according to the wall height and the working tilt angle, nor can it flexibly adapt to the suspension requirements of different external extension distances, resulting in poor adaptability to complex working environments. Third, the wall-mounted positioning adopts the method of adjusting the end plate of the bolt to tighten against the wall in conjunction with the tie bolt, which is only a one-sided tightening structure and does not form a two-way clamping of the wall. During operation, it is easy to shake due to the horizontal force, affecting the suspension accuracy and safety.

[0004] It is evident that existing wall-mounted suspension systems have significant technical shortcomings in terms of operational flexibility, stability, and adaptability. Therefore, the industry urgently needs to develop a new type of suspension system that can solve these problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing suspended basket systems, such as poor operational flexibility and structural stability, and limited adaptability, and to provide a lifting and wall-mounted mobile suspension device.

[0006] This utility model is achieved through the following technical solution: a lifting, wall-mounted, mobile suspension device, comprising a mobile base and casters mounted on the bottom of the mobile base; a retractable main support arm is rotatably connected to the top of the mobile base, the main support arm is inclined, and a hydraulic support cylinder is provided between the main support arm and the mobile base, with both ends of the hydraulic support cylinder rotatably connected to the mobile base and the main support arm respectively; a retractable support arm is rotatably connected to the end of the main support arm away from the mobile base, and a retractable suspension actuator is provided at the top of the support arm. The bottom of the supporting arm can abut against the top of the movable base, and the supporting arm can be close to the side of the wall; both ends of the suspension actuator are respectively provided with pulley assemblies, and steel wire ropes are wound around the pulley assemblies. One end of the steel wire rope is connected to the suspended object, and the other end of the steel wire rope is connected to a winch installed on the top of the movable base through a guide wheel; the bottom of the suspension actuator is provided with a wall limiting block near the edge of the wall. Through the extension and retraction of the suspension actuator, the wall limiting block and the supporting arm can cooperate to clamp and position the wall.

[0007] This device allows for flexible relocation of work sites without disassembly via casters at the bottom of the movable base, significantly improving site switching efficiency. A hydraulic support cylinder drives the retractable main support arm to flexibly adjust the tilt angle and working radius, adapting to different work scenarios. The rotating connection at both ends of the hydraulic support cylinder ensures smooth and stable adjustment. The retractable support arm adapts to wall height and provides dual stable support by abutting the movable base at the bottom and pressing against the wall on the side, distributing loads and preventing structural deformation. A retractable suspension actuator drives the wall-mounted limit block to clamp and position the support arm against the wall, effectively counteracting horizontal forces and preventing swaying during operation, thus improving stability and suspension accuracy. Combined with the pulley assembly's balanced force distribution at both ends and the winch and wire rope precisely driving the lifting and lowering of the suspended object, the overall device achieves a comprehensive range of benefits, including flexible movement, strong adaptability, stable wall-mounted operation, and precise and safe suspension lifting.

[0008] A further improvement of this utility model is that the main support arm includes a support adjustment arm and a support sub-arm. The support adjustment arm is slidably sleeved on the support sub-arm, and the support adjustment arm and the support sub-arm are positioned by a multi-segment pin structure. The end of the support adjustment arm away from the support sub-arm and the end of the support sub-arm away from the support adjustment arm are rotatably connected to the top of the movable base and the side of the support arm, respectively, by a hinge assembly.

[0009] A further improvement of this utility model is that the supporting arm includes a telescopic positioning strut and a telescopic vertical strut, both of which are telescopic rods positioned by a multi-segment pin structure; the telescopic positioning strut and the telescopic vertical strut are connected end to end, the end of the telescopic positioning strut away from the telescopic vertical strut is connected to the suspension actuator, and the end of the telescopic vertical strut away from the telescopic positioning strut can abut against the top of the movable base. A further improvement of this utility model is that the suspension actuator includes an adjusting horizontal arm and a horizontal arm extension mechanism, both of which are telescopic rods positioned by a multi-segment pin structure; the adjusting horizontal arm and the horizontal arm extension mechanism are connected end to end, and the two pulley assemblies are respectively disposed at the end of the horizontal arm extension mechanism away from the adjusting horizontal arm and the end of the adjusting horizontal arm away from the horizontal arm extension mechanism; the adjusting horizontal arm is disposed on the supporting vertical arm, and the wall limiting block is disposed at the bottom of the adjusting horizontal arm.

[0010] A further improvement of this utility model is that the adjusting cross arm and the wall limiting block form an L-shaped structure. Through the extension and retraction of the adjusting cross arm, the wall limiting block and the supporting upright arm can cooperate to clamp and position the wall.

[0011] A further improvement of this utility model is that the top of the supporting arm is provided with a reinforcing abutment that can be closely pressed against the side of the wall.

[0012] A further improvement of this utility model is that the omnidirectional wheel is mounted on the bottom of the movable base via an auxiliary bracket.

[0013] A further improvement of this utility model is that a push handle is provided on the top of the movable base near the connection between the main support arm and the movable base.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are: 1. This device can be flexibly moved to the work site without disassembly by means of a mobile base and casters, and can be easily and accurately parked with the push handle; the telescopic main support arm can be adjusted to multiple angles through a hydraulic support cylinder, and the multi-stage telescopic design of the support arm and the suspension actuator can adapt to different wall heights, working radii and external reach distances, without the need to customize equipment for different scenarios, and is suitable for various work needs such as building construction and decoration.

[0015] 2. This device uses a clamping and positioning structure formed by the support arm being close to the wall and the wall limiting block to effectively counteract horizontal forces and prevent swaying during operation. The reinforcing plate at the top of the support arm increases the contact area, disperses pressure to prevent damage to the wall, and improves anti-slip capability, ensuring accurate lifting of suspended objects and reducing safety hazards in high-altitude operations.

[0016] 3. This device reduces wire rope wear through the pulley assembly design; the winch drive combined with the guide wheel enables precise lifting and lowering of suspended objects; the pin positioning operation of each telescopic component is simple; the bottom abutment design of the auxiliary bracket and support arm enhances structural strength and extends the device's lifespan; the overall design balances safety, convenience, and durability, and is applicable to a wide range of scenarios.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Now refer to Figure 1-3The following is a description of a specific embodiment: The present invention provides a lifting, wall-mounted, mobile suspension device, comprising a mobile base 2 and casters 1 mounted on the bottom of the mobile base 2; a retractable main support arm 3 is rotatably connected to the top of the mobile base 2, the main support arm 3 is inclined, and a hydraulic support cylinder 13 is provided between the main support arm 3 and the mobile base 2, with both ends of the hydraulic support cylinder 13 rotatably connected to the mobile base 2 and the main support arm 3 respectively; a retractable support arm is rotatably connected to the end of the main support arm 3 away from the mobile base 2, and a retractable suspension actuator is provided at the top of the support arm. The bottom of the support arm can abut against the top of the movable base 2, and the support arm can be close to the side of the wall 17; both ends of the suspension actuator are respectively provided with pulley assemblies 11, and steel wire ropes 16 are wound around the pulley assemblies 11. One end of the steel wire rope 16 is connected to the suspended object, and the other end of the steel wire rope 16 is connected to the winch installed on the top of the movable base 2 through the guide wheel 201; the bottom of the suspension actuator is provided with a wall limiting block 12 near the edge of the wall 17. Through the extension and retraction of the suspension actuator, the wall limiting block 12 cooperates with the support arm to clamp and position the wall 17.

[0024] During operation, the entire device is first moved to the work point near the wall 17 using the casters 1 at the bottom of the movable base 2. The casters 1 allow for flexible movement of the device without disassembly, significantly improving the efficiency of work point switching. After being moved into position, the main support arm 3 is adjusted by the extension and retraction of the hydraulic support cylinder 13 around its rotating connection with the movable base 2. The extension and retraction function of the main support arm 3 can adapt to different working radius requirements, and the rotating connection design at both ends of the hydraulic support cylinder 13 ensures smooth angle adjustment and stable support. Subsequently, the extension and retraction of the support arm is adjusted to adapt to the height of the wall 17. The bottom of the support arm abuts against the top of the movable base 2 to form stable support, while the support arm is initially positioned close to the side of the wall 17. Next, the telescopic suspension actuator moves the bottom wall limiting block 12 close to the edge of the wall 17. Through the extension and retraction control of the suspension actuator, the wall limiting block 12 and the support arm cooperate to clamp and position the wall 17. This clamping structure, compared to single-sided clamping, can effectively counteract horizontal forces, preventing the device from shaking during operation and improving stability. Finally, the winch on top of the mobile base 2 is started. The steel wire rope 16 is guided by the guide wheel 201 and then passes around the pulley assembly 11 at both ends of the suspension actuator to drive the suspended object to rise and fall. The pulley assembly 11 is designed at both ends to distribute the force evenly, ensuring that the suspended object rises and falls smoothly and accurately.

[0025] Specifically, refer to Figure 1The main support arm 3 includes a support adjustment arm 4 and a support sub-arm 5. The support adjustment arm 4 is slidably sleeved on the support sub-arm 5. The support adjustment arm 4 and the support sub-arm 5 are positioned by a multi-segment pin structure. The end of the support adjustment arm 4 away from the support sub-arm 5 and the end of the support sub-arm 5 away from the support adjustment arm 4 are rotatably connected to the top of the movable base 2 and the side of the support arm respectively through a hinge assembly 14.

[0026] The main support arm 3 of this device has an adjustable support arm 4 that can slide along the support sub-arm 5 to achieve length extension and retraction. Positioning is achieved by inserting a multi-segment pin structure into corresponding holes, allowing for a wider range of length adjustment for the main support arm 3 and adapting to different working distances. The pin positioning method is simple to operate and reliable. The adjustable support arm 4 is rotatably connected to the movable base 2, and the support sub-arm 5 is rotatably connected to the support arm via a hinge assembly 14. Combined with the drive of the hydraulic support cylinder 13, the main support arm 3 can be flexibly adjusted at multiple angles, ensuring that the support arm can accurately conform to walls 17 with different inclinations, thus improving the device's adaptability to complex working environments.

[0027] Specifically, refer to Figure 1 The supporting arm includes a telescopic positioning strut 7 and a telescopic vertical strut 8. Both the telescopic positioning strut 7 and the telescopic vertical strut 8 are telescopic rods positioned by a multi-segment pin structure. The telescopic positioning strut 7 and the telescopic vertical strut 8 are connected end to end. The end of the telescopic positioning strut 8 away from the telescopic vertical strut 7 is connected to the suspension actuator. The end of the telescopic vertical strut 7 away from the telescopic positioning strut 8 can abut against the top of the movable base 2.

[0028] The telescopic positioning strut 7 and telescopic vertical strut 8 of this device achieve telescopic positioning through a multi-segment pin structure. Connected end-to-end, they can work together to adjust the overall height of the supporting arm, adapting to both low walls and high-altitude operations. The adjustment range is wide and the positioning is stable. The end of the telescopic vertical strut 7 furthest from the telescopic positioning strut 8 rests against the top of the movable base 2, forming a stable force-bearing structure of "bottom support + top connection to the suspension actuator." This disperses the gravitational load of the suspended object, preventing deformation of the supporting arm due to concentrated stress and extending the device's service life.

[0029] Specifically, refer to Figure 1 The suspension actuator includes an adjusting crossarm 9 and a crossarm extension mechanism 10. Both the adjusting crossarm 9 and the crossarm extension mechanism 10 are telescopic rods positioned by a multi-segment pin structure. The adjusting crossarm 9 and the crossarm extension mechanism 10 are connected end to end. Two pulley assemblies 11 are respectively located at the end of the crossarm extension mechanism 10 away from the adjusting crossarm 9 and the end of the adjusting crossarm 9 away from the crossarm extension mechanism 10. The adjusting crossarm 9 is located on the supporting vertical arm, and the wall limiting block 12 is located at the bottom of the adjusting crossarm 9.

[0030] The adjustable crossarm 9 and the crossarm extension mechanism 10 of this device's suspension actuator are telescopically connected via a multi-segment pin structure, allowing for flexible adjustment of the overall outward extension length to meet the suspension operation requirements of different outward extension distances—such as construction areas at different depths outside the wall. Two pulley assemblies 11 are respectively located at both ends of the crossarm extension mechanism 10 and the adjustable crossarm 9, making the force distribution of the wire rope 16 more balanced, reducing the load pressure on a single pulley, preventing the rope from wearing and breaking due to excessive local stress, and improving the safety of suspension operations. The adjustable crossarm 9 is connected to the supporting vertical arm, and the wall limiting block 12 is located at the bottom of the adjustable crossarm 9, ensuring coordinated operation of clamping positioning and suspension execution functions, simplifying the operation process.

[0031] Specifically, refer to Figure 1 The adjusting horizontal arm 9 and the wall limiting block 12 form an L-shaped structure. Through the extension and retraction of the adjusting horizontal arm 9, the wall limiting block 12 and the supporting vertical arm can cooperate to clamp and position the wall 17.

[0032] The adjusting horizontal arm 9 and the wall limiting block 12 of this device form an L-shaped structure. One side of the L-shape extends and retracts with the adjusting horizontal arm 9, approaching the outer side of the wall 17. The other side, namely the wall limiting block 12, fits against the bottom edge of the wall 17. By adjusting the extension and retraction of the horizontal arm 9, the L-shaped structure and the supporting vertical arm cooperate to form a three-dimensional clamping structure of "horizontal + longitudinal". Compared with planar clamping, it can fit the contour of the wall 17 more closely. Even if there are slight bumps on the surface of the wall 17, it can still clamp stably, further reducing shaking during operation and improving the positioning accuracy of the suspended object.

[0033] In one embodiment, reference Figure 2 and Figure 3 The top of the supporting arm is provided with a reinforcing abutment 6 that can be close to the side of the wall 17.

[0034] This device increases the contact area with the side of the wall 17 by using a reinforcing plate 6 at the top of the support arm. When the support arm is close to the wall 17, the reinforcing plate 6 can distribute the pressure of the support arm to a larger area of ​​the wall 17, avoiding damage to the surface of the wall 17 due to excessive local pressure—especially suitable for brittle wall materials. At the same time, it increases the friction with the wall 17, improves the anti-slip ability of the support arm, and enhances the overall structural stability.

[0035] In one embodiment, reference Figure 1 and Figure 2 The omnidirectional wheel 1 is mounted on the bottom of the movable base 2 via an auxiliary bracket 15.

[0036] The caster wheel 1 of this device is mounted on the bottom of the mobile base 2 via an auxiliary bracket 15. The auxiliary bracket 15 enhances the connection strength between the caster wheel 1 and the mobile base 2, making it less likely for the caster wheel 1 to fall off or deform due to excessive force when the device is carrying heavy objects or moving on rough ground. This improves the structural reliability during movement and extends the service life of the caster wheel 1.

[0037] In one embodiment, reference Figure 2 and Figure 3 The top of the movable base 2 is provided with a push handle 202 near the connection between the main support arm 3 and the movable base 2.

[0038] The push handle 202 on the top of the mobile base 2 of this device is located near the connection between the main support arm 3 and the mobile base 2. The operator can easily push the device to move by pushing the handle 202. By using the lever principle, the pushing force is saved. Especially when the device is carrying heavy objects, the direction of movement can be controlled more easily, making it easier to accurately stop the device at the target work point and improve the ease of operation.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
