Description

Technical Field

[0001] This utility model relates to the field of lifting construction equipment technology, and in particular to a construction platform. Background Technology

[0002] In today's society filled with high-rise buildings, elevators have become an indispensable piece of equipment for every high-rise building. However, due to the height of the building, the installation of elevator shafts or elevators is quite difficult. Therefore, installers often need to use a construction platform to install elevator shafts or elevators.

[0003] Construction platforms typically include a frame, a hoisting rope retraction device, a hoisting rope, and a controller. The controller drives the hoisting rope retraction device to raise and lower the construction platform for elevator shaft or elevator installation. However, existing construction platforms only have support at both ends for the hoisting rope. During the hoisting process driven by the hoisting rope retraction device, the hoisting rope is prone to unstable swaying, leading to unstable shaking of the construction platform. This not only exacerbates wear between the construction platform and the elevator guide rails but also poses certain safety risks. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide a construction platform whose structure can reduce the swing of the lifting rope during the lifting process, which helps to improve the stability of the construction platform lifting, reduce the frictional loss between the construction platform and the elevator guide rail, and improve safety.

[0005] This utility model is achieved through the following technical solution: a construction platform, including a frame, at least one lifting rope winding and unwinding device, a lifting rope, and a balancing device; the lifting rope winding and unwinding device is disposed on the frame, and the balancing device is disposed above the lifting rope winding and unwinding device. The balancing device includes a mounting frame and several limiting components. The mounting frame is connected to the frame, and the several limiting components are sequentially disposed on the mounting frame along the same vertical direction. The limiting components define a channel for the lifting rope to pass through, and the lifting rope passes through the channel sequentially and connects to the lifting rope winding and unwinding device.

[0006] Compared with the prior art, the construction platform provided by this utility model, by setting several limiting components above the lifting rope winding device, limits the channel for the lifting rope to pass through, effectively constrains the swing amplitude of the lifting rope during the lifting process, helps to improve the stability of the construction platform lifting, reduces frictional loss between the construction platform and the elevator guide rail, and improves safety.

[0007] Furthermore, the limiting component includes at least one set of fixed pulleys, each set comprising two fixed pulleys rotatably mounted on the mounting frame. Each fixed pulley has a rope groove extending circumferentially on its circumferential surface. The two fixed pulleys are respectively positioned on either side of the lifting rope, and the two rope grooves define the channel. By using the fixed pulley set for limiting the lifting, the rolling friction between the lifting rope and the fixed pulleys helps reduce resistance during the lifting process and minimizes wear on the lifting rope.

[0008] Furthermore, the two fixed pulleys are located at the same height, and the two rope grooves are arranged opposite each other. This reduces the swaying of the lifting rope caused by the height difference between the two fixed pulleys, further reducing the swaying of the lifting rope.

[0009] Furthermore, the limiting component includes two sets of fixed pulleys. The projections of the two sets of fixed pulleys on the horizontal plane form a cross shape, and the channels formed by each set of fixed pulleys extend in the same vertical direction. The two sets of fixed pulleys limit the forward and backward movement and the left and right movement of the lifting rope at two positions, significantly reducing the swaying of the lifting rope and improving the stability of the lifting rope and the lifting of the construction platform.

[0010] Furthermore, the mounting frame includes two uprights and several connecting plates. The uprights are all mounted on the frame, and the two uprights are connected by the connecting plates. The limiting components are correspondingly mounted on the connecting plates, and the connecting plates have through holes at the positions corresponding to the limiting components. The through holes are used for the lifting rope to move through.

[0011] Furthermore, there are two lifting rope retraction devices, and the balancing devices are correspondingly positioned above each of the lifting rope retraction devices. Using a dual lifting rope retraction device helps improve lifting efficiency and increases the safety factor.

[0012] Furthermore, it also includes reinforcing components, which are respectively connected to the two mounting brackets. Connecting the two mounting brackets together with these reinforcing components creates a more stable overall structure, which helps to enhance the structural stability of the two mounting brackets and improve their load-bearing capacity.

[0013] Furthermore, the frame is provided with two worktables, which are arranged opposite each other and can move in a direction away from or towards each other. The lifting rope winding and unwinding device is arranged between the two worktables.

[0014] Furthermore, the frame includes a frame body and two guardrails disposed on the frame body. The workbench is disposed between the two guardrails. The workbench includes a pedal bracket and a pedal for worker operation. The pedal bracket is connected to the two guardrails via a telescopic rod or guide rail, and the pedal is disposed on the pedal bracket. The adjustable workbench design allows the construction platform to be applied to construction environments in different spaces.

[0015] Furthermore, the pedal bracket has an inlet / outlet on the side away from the lifting rope retraction device, and a safety door chain is installed on the inlet / outlet to improve safety.

[0016] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1 to 3 As shown, this embodiment provides a construction platform, including a frame 10, a lifting rope winding and unwinding device 20, a lifting rope (not shown), and a balancing device 40. The lifting rope winding and unwinding device 20 is disposed on the frame 10, and the balancing device 40 is disposed above the lifting rope winding and unwinding device 20. The lifting rope is connected to the lifting rope winding and unwinding device 20 through the balancing device 40.

[0023] The frame 10 includes a frame body 11 and a crossbeam 12. The crossbeam 12 is located below the frame body 11 and connected to it. A guide shoe (not shown) is provided at the end of the crossbeam 12, and the guide shoe is slidably connected to a guide rail within the elevator shaft. The cooperation between the guide shoe and the guide rail provides necessary guidance and support for the lifting and lowering operation of the construction platform.

[0024] The lifting rope winding and unwinding device 20 is located directly above the crossbeam 12 and is fixedly connected to the frame 11. The lifting rope winding and unwinding device 20 is a hoist. It should be noted that the hoist is existing technology and typically includes a drive motor and a winding shaft. One end of the lifting rope is fixed to the top of the elevator shaft or suspended at the construction site via a support column, and the other end of the lifting rope is connected to the winding shaft. The drive motor drives the winding shaft to wind and unwind the lifting rope, achieving lifting and lowering. In this embodiment, there are two lifting rope winding and unwinding devices 20, arranged opposite each other and both located directly above the crossbeam 12. Of course, in other alternative embodiments, the number of lifting rope winding and unwinding devices 20 is not limited to two; it can be one, four, or other numbers.

[0025] The frame 10 also includes two guardrails 13, which are disposed on the frame body 11 and located near the two ends of the crossbeam 12. Two workbenches 50 are disposed between the two guardrails 13, facing each other. Each workbench 50 includes a pedal support 51 and a pedal 52. The pedal support 51 is connected to the two guardrails 13 via a telescopic rod or guide rail. The pedal 52 is mounted on the pedal support 51 and used for worker operation. The lifting rope retraction device 20 is located between the two workbenches 50. Through this arrangement, the two workbenches 50 can move towards or away from each other, allowing the construction platform to be used in different spatial construction environments and improving its flexibility.

[0026] Furthermore, the pedal bracket 51 is provided with an inlet and outlet on the side away from the lifting rope retraction device 20, and a safety door chain 53 is provided on the inlet and outlet to improve safety.

[0027] Two balancing devices 40 are provided, each corresponding to one of the lifting rope take-up and release devices 20. Each balancing device 40 includes a mounting frame 41 and several limiting components 42. The mounting frame 41 is connected to the frame body 11. The limiting components 42 are sequentially arranged on the mounting frame 41 along the same vertical direction, defining channels for the lifting rope to pass through. The lifting rope passes through these channels and connects to the lifting rope take-up and release device 20. By defining these channels through the limiting components 42, the swing amplitude of the lifting rope during lifting is effectively constrained, which helps improve the stability of the construction platform during lifting, reduces frictional wear between the construction platform and the elevator guide rail, and improves safety.

[0028] Specifically, the mounting frame 41 includes two uprights 411 and two connecting plates 412. Both uprights 411 are connected to the frame body 11, and the two connecting plates 412 are positioned between the two uprights 411, with each end of the connecting plate 412 connected to one of the two uprights 411. Each limiting component 42 is correspondingly disposed on one of the connecting plates 411. Each connecting plate 412 has a through hole at the position corresponding to the limiting component 42, allowing the lifting rope to pass through. In this embodiment, the connecting plates 412 and the uprights 411 are connected by welding. Of course, in other alternative embodiments, the connecting plates 412 can be connected to the uprights 411 by a detachable method such as screws. Of course, in other alternative embodiments, the connecting plates 412 and the uprights 411 can also be an integral design. Furthermore, it should be noted that the number of connecting plates 412 and limiting components 42 is not limited to two; there can be more than two.

[0029] The limiting component 42 includes at least one set of fixed pulleys, each set comprising two fixed pulleys rotatably mounted on the connecting plate 412. Each fixed pulley has a rope groove extending circumferentially on its circumferential surface. The two fixed pulleys are at the same height, and the two rope grooves are opposite to each other, thus defining a channel for the lifting rope to pass through. Alternatively, in other alternative embodiments, the two fixed pulleys can be at different heights, i.e., vertically positioned, and respectively located on both sides of the lifting rope, thereby defining a channel for the lifting rope to pass through. In this embodiment, the fixed pulley set also includes a pulley bracket, on which the fixed pulleys are rotatably mounted, and the pulley bracket is installed on the connecting plate. Alternatively, in other alternative embodiments, the fixed pulleys can be rotatably mounted on the mounting frame via a pivot.

[0030] Preferably, the limiting component 42 includes two sets of fixed pulleys. One set of fixed pulleys is disposed on the upper surface of the connecting plate 412, and the other set of fixed pulleys is disposed on the lower surface of the connecting plate 412. The projections of the two sets of fixed pulleys on the horizontal plane form a cross shape, and the channels formed by the two sets of fixed pulleys extend in the same vertical direction and are connected to the through holes on the connecting plate. By limiting the forward and backward movement and the left and right movement of the lifting rope at the upper and lower positions respectively, the swaying of the lifting rope can be significantly reduced, and the stability of the lifting rope and the construction platform during lifting can be improved. Of course, in other alternative embodiments, the limiting component 40 may include two limiting plates and a plurality of rolling columns. The two limiting plates are respectively disposed on both sides of the lifting rope and mounted on the mounting bracket 412. The two limiting plates have rolling column receiving grooves on the side facing the lifting rope. The plurality of rolling columns are rotatably disposed in the rolling column receiving grooves. The circumferential surface of the rolling columns has grooves for the lifting rope to move through. The plurality of grooves on the two limiting plates define a channel for the lifting rope to move through. It should be noted that the two limiting plates may be disposed opposite to each other or one above the other.

[0031] In this embodiment, a reinforcing component, namely a gantry frame 60, is also included. The gantry frame 60 is positioned above the two balancing devices 40, with one end connected to a connecting plate 412 located on top of one of the mounting frames 41, and the other end connected to a connecting plate 412 on top of the other mounting frame 41. Connecting the two mounting frames 41 together via the gantry frame 60 forms a more stable overall structure, which helps to enhance the structural stability of the two mounting frames 41 and improve their load-bearing capacity. Of course, in other alternative embodiments, the reinforcing component is not limited to the structural form of the gantry frame 60; it can be several connecting columns, with both ends of each column connected to the uprights in the two mounting frames 41, thereby reinforcing the two mounting frames 41.

[0032] Compared with the prior art, the construction platform provided by this utility model, by setting several limiting components above the lifting rope winding device, limits the channel for the lifting rope to pass through, effectively constrains the swing amplitude of the lifting rope during the lifting process, helps to improve the stability of the construction platform lifting, reduces frictional loss between the construction platform and the elevator guide rail, and improves safety.
