Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and particularly relates to a hanging basket for construction engineering construction. Background Art

[0002] A construction hanging basket is a device used for high-altitude operations, mainly for high-altitude operations such as the external wall construction of high-rise buildings, curtain wall installation, thermal insulation construction, and maintenance and cleaning of the external wall. The hanging basket is a new type of high-altitude operation device that can replace traditional scaffolding, reduce labor intensity, improve work efficiency, and can be reused.

[0003] The construction hanging basket mainly consists of a suspension mechanism, a basket body, and a hoisting mechanism. Its suspension mechanism and the top hoisting mechanism jointly balance the weight of the basket body through steel wires. However, in actual use, construction workers need to constantly pay attention to the problem of the center of gravity balance of the hanging basket. When construction workers move in the basket body or the loads on both sides of the basket body change, the hanging basket will tilt and even shake, affecting the work of construction workers. If the balance is not maintained in time, the hanging basket will collide with the wall and glass, causing economic losses. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a hanging basket for construction engineering construction, which can automatically maintain the center of gravity balance when the load of the hanging basket changes.

[0005] An embodiment of the present invention provides a hanging basket for construction engineering construction, including:

[0006] A basket body, above the bottom plate of which there are multiple pedals, and the pedals are slidably matched with the side wall of the basket body in the vertical direction;

[0007] A counterweight box, fixed at the lower end of the basket body, and multiple groups of counterweight adjustment components are fixed in the counterweight box, and each group of counterweight adjustment components corresponds to one pedal; wherein,

[0008] Each group of counterweight adjustment components includes: a gear-rack pair, a crank-slider assembly, and a counterweight block. The upper end of the rack of the gear-rack pair is fixedly connected with the pedal, and the gear is fixed below the bottom plate; the crank of the crank-slider assembly is coaxially connected with the gear, the slideway of the crank-slider assembly is horizontally fixed in the counterweight box, the slider of the crank-slider assembly is slidably matched with the slideway, the counterweight block is fixedly connected with the slider, and the gear and the slider are located on opposite sides of the basket body.

[0009] Optionally, multiple groups of disc springs are arranged below the pedals, and the multiple groups of disc springs are connected between the bottom plate and the pedals.

[0010] Optionally, two groups of crank-slider assemblies share one slideway.

[0011] Optionally, two limit blocks are fixed on the gear, the limit blocks are arranged on the same side as the crank of the crank-slider assembly, and the two limit blocks are symmetric about the axis of the gear.

[0012] Optionally, the crank of the crank slider assembly is a telescopic rod.

[0013] Optionally, the slide is a double-guide rail slide, and each slider is slidably matched with the double guide rails of the slide.

[0014] Optionally, each slider is connected to a plurality of counterweight blocks, and the plurality of counterweight blocks are connected by quick-insert bolts.

[0015] Optionally, buffer blocks are provided at the center and the end of the slideway.

[0016] The technical solution provided by the embodiment of the present invention has the following advantages over the prior art: when the construction personnel move in the hanging basket, the pedal pressure drives the pedal to produce vertical displacement, and the displacement is transmitted to the gear rack pair through the rigidly connected rack, driving the gear to rotate, and the crank fixed coaxially with the gear converts the rotational motion into the horizontal sliding of the slider of the crank slider assembly in the slideway, and the counterweight fixed to the slider is synchronously displaced along the guide rail in the opposite direction of the personnel movement, thereby maintaining the center balance of the entire hanging basket and preventing the hanging basket from tilting during the construction process. The rack is driven by the vertical movement of the pedal, which drives the gear to rotate and links the crank slider assembly, so that the counterweight moves horizontally to achieve dynamic balance, greatly reducing the external force required for operation, using vertical guide rails to ensure accurate and stable pedal movement, and the symmetrically arranged counterweight system enhances the anti-drift ability. The modular counterweight design can flexibly adjust the load matching, and the standardized slide rails and wear-resistant transmission components take into account durability and maintenance convenience. The overall solution has the characteristics of efficient energy conversion, stability and reliability, and strong adaptability, while reducing energy consumption and improving operating comfort and safety.

Figure 2 It is a schematic diagram of the structure inside the counterweight box provided by the embodiment of the present invention. Figure 3 It is a top view of the counterweight box provided by the embodiment of the present invention. Figure 4 It is a connection schematic diagram of the disc spring provided by the embodiment of the present invention. Figure 5 is Figure 3 an enlarged schematic diagram of the structure at A in

[0028] As Figure 1 and Figure 2 shown, the embodiment of the present invention provides a suspended platform for construction engineering, including:

[0029] A basket body 1, above the bottom plate 100 of which there are multiple pedals 2, and the pedals 2 are slidably matched with the side wall of the basket body 1 in the vertical direction;

[0030] The counterweight box 101 is fixed at the lower end of the basket body 1. A plurality of counterweight adjustment components are fixed in the counterweight box 101. Each counterweight adjustment component corresponds to a pedal 2.

[0031] Each set of counterweight adjustment components includes: a gear rack pair 3, a crank slider assembly 4 and a counterweight block 5. The upper end of the rack 300 of the gear rack pair 3 is fixedly connected to the pedal 2, and the gear 301 is fixed under the base plate 100; the crank 400 of the crank slider assembly 4 is coaxially connected to the gear 301, the slideway 401 of the crank slider assembly 4 is horizontally fixed in the counterweight box 101, the slider 402 of the crank slider assembly 4 is slidably matched with the slideway 401, the counterweight block 5 is fixedly connected to the slider 402, and the gear 301 and the slider 402 are respectively located on opposite sides of the basket body 1.

[0032] Specifically, the basket body 1 serves as the core bearing structure, and its base plate 100 is made of high-strength material. The counterweight box 101 is fixed to the bottom of the basket body 1 by bolts. The upper end of the rack 300 passes through the base plate 100 and is welded to the bottom of the pedal 2. The gear rack pair 3 is made of high-carbon chromium bearing steel. The pedal 2 and the side wall of the basket body 1 are slidably matched through vertical slide rails or guide grooves. The slideway 401 is horizontally welded to the inner wall of the counterweight box 101, and the surface polishing ensures low-resistance sliding. The slider 402 is equipped with a ball bearing, and the slider 402 is fixed to the counterweight block 5 by bolts. The counterweight block 5 is made of cast iron, and the counterweight box 101 adopts a modular design.

[0033] The embodiment of the present invention realizes dynamic balance adjustment through mechanical linkage, and the specific operation process is as follows: when the construction personnel move in the hanging basket, their pedal pressure drives the pedal 2 to produce vertical displacement, and the displacement is transmitted to the gear rack pair 3 through the rigidly connected rack 300, driving the gear 301 to rotate, and the crank 400 coaxially fixed with the gear 301 converts the rotational motion into the horizontal sliding of the slider 402 of the crank slider assembly 4 in the slideway 401, and the counterweight block 5 fixed on the slider 402 is synchronously displaced along the guide rail in the opposite direction of the personnel's movement, thereby maintaining the central balance of the entire hanging basket and preventing the hanging basket from tilting during construction. The rack 300 is driven by the vertical movement of the pedal 2, which drives the gear 301 to rotate and links the crank slider assembly 4, so that the counterweight block 5 moves horizontally to achieve dynamic balance, greatly reducing the external force required for operation. The vertical guide rail is used to ensure the precise and stable movement of the pedal 2, and the symmetrically arranged counterweight system enhances the anti-drift ability; the modular counterweight block 5 design can flexibly adjust the load matching, while the standardized rails and wear-resistant transmission components take into account durability and easy maintenance. The overall solution has the characteristics of efficient energy conversion, stability and reliability, and strong adaptability, which reduces energy consumption while improving operating comfort and safety.

[0034] Optional, reference Figure 1, the number of pedals 2 is three, namely: the left bearing plate 200, the central bearing plate 201 and the right bearing plate 202, forming a continuous bearing plane. The left bearing plate 200 and the right bearing plate 202 are respectively and independently connected to a set of gear-rack pairs 3, and the two sets of gear-rack pairs 3 are respectively and independently connected to a set of crank-slider assemblies 4.

[0035] Specifically, the gap between adjacent pedals 2 is ≤ 3 mm, and the surface is provided with anti-slip patterns. The left bearing plate 200 is connected to the left gear-rack pair 3, and the right bearing plate 202 is connected to the right gear-rack pair 3. The pedal 2 adopts a segmented layout and consists of the left bearing plate 200, the central bearing plate 201 and the right bearing plate 202 to form a continuous tread surface. The left bearing plate 200 and the right bearing plate 202 are respectively and independently connected to the corresponding gear-rack pairs 3. The upper end of the rack 300 of each set of gear-rack pairs 3 is connected to the corresponding side pedal 2, and the lower end is meshed with the gear 301. The gears 301 of the two sets of gear-rack pairs 3 are respectively coaxially connected to independent crank-slider assemblies 4, and the corresponding sliders 402 on the corresponding sides are driven to slide in the slideway 401 through the cranks 400, thereby driving the counterweight 5 to move in the opposite direction. When a person steps on the left bearing plate 200 or the right bearing plate 202 with eccentric load, the rack 300 on the compressed side drives the gear 301 to rotate, and the corresponding counterweight 5 is pushed to displace in the opposite direction through the crank 400. The central position is the center of the hanging basket, and the central bearing plate 201 is not connected to the counterweight adjustment assembly, avoiding force transmission interference while maintaining the continuity of the tread surface. The independent operating mechanism of the bilateral gear-rack pairs 3 and the crank-slider assemblies 4 can accurately sense the eccentric load position and perform differential compensation, while the independent floating design of the central bearing plate 201 ensures uniform distribution of the stepping force. This split structure enables the hanging basket to maintain dynamic stability under complex working conditions.

[0036] Optionally, refer to Figure 4 , multiple sets of disc springs 203 are arranged under the pedal 2, and the multiple sets of disc springs 203 are connected between the bottom plate 100 and the pedal 2.

[0037] Specifically, standard disc springs 203 are used and evenly distributed in a matrix between the bottom plate 100 and the three pedals 2. The disc springs 203 can provide an initial supporting force. When a person leaves the current bearing plate, the disc springs 203 push the bearing plate to smoothly return to the initial horizontal position. The disc springs 203 provide a small resistance at the initial stage of deformation to ensure the sensitivity of the pedal 2, and automatically increase the reset force as the deformation amount increases, avoiding impact and vibration. The circumferential even distribution design of the multiple sets of disc springs 203 enables all parts of the bearing plate to be reset synchronously, preventing unilateral jamming. The pre-compression amount of the spring group is adjustable and can adapt to the load requirements of construction workers with different weights. The disc spring 203 assembly provides sufficient reset torque.

[0038] Optionally, refer to Figure 3 , the two sets of crank-slider assemblies 4 share a slideway 401.

[0039] Specifically, the slideway is made of high-strength aluminum alloy profiles. A T-shaped isolation boss is arranged in the middle of the slideway, dividing the effective stroke into two independent intervals to ensure that the bilateral sliders 402 move without interference. The sliders 402 of the two crank-slider assemblies 4 share the same horizontal slideway 401. Through the bidirectional sliding guiding function of the slideway 401, the left and right counterweights 5 can maintain accurate trajectory coincidence during reverse movement. The rigid support of the shared slideway 401 ensures that the bilateral counterweights 5 move without interference. The integrated design of the slideway 401 reduces the number of components and improves the structural reliability. The reverse linkage of the bilateral sliders 402 in a single slideway 401 forms a symmetric compensation path, enhancing the coordination of moment balance. At the same time, as the core load-bearing component inside the counterweight box 101, the slideway 401 optimizes the force transmission path and reduces the risk of structural deformation. Through the spatial reuse of the slideway 401, both the independent adjustment function of the bilateral counterweights 5 is maintained and a compact layout is achieved.

[0040] Optionally, referring to Figure 5 , two limit blocks 302 are fixed on the gear 301. The limit blocks 302 are arranged on the same side as the crank 400 of the crank-slider assembly 4, and the two limit blocks 302 are symmetric about the axis of the gear 301.

[0041] Specifically, two high-strength alloy steel limit blocks 302 are symmetrically arranged at 180° on both sides of the axis of the gear 301 to ensure that the stroke of the pedal 2 does not exceed the design maximum value, and the crank-slider assembly 4 is always within the optimal transmission angle range, eliminating the incorrect counterweight action caused by reverse dead space. The limit blocks 302 are installed on the same side as the crank 400, and their working surfaces are precision ground to ensure the cooperation between the limit blocks 302 and the boss structure on the end face of the gear 301, avoiding the dead point position of the mechanism. When the personnel suddenly evacuate the pedal 2, the limit blocks 302 can lock the inertial swing of the crank 400 to prevent the counterweight slider 402 from hitting the end of the guide rail due to overshoot. The symmetrically arranged limit blocks 302 can also automatically balance the radial force on the gear 301 and reduce bearing wear.

[0042] Optionally, referring to Figure 2 , the crank 400 of the crank-slider assembly 4 is a telescopic rod.

[0043] Specifically, the telescopic crank 400 is composed of an inner and an outer sleeve, made of 42CrMo, surface-hardened by chromium plating, and equipped with an internal spiral adjustment mechanism. The crank 400 adopts a telescopic design, and the following optimizations are achieved by adjusting the length of the driving arm: the telescopic structure manually adjusts the arm length to adapt to the counterweight requirements of construction workers with different weights. In terms of safety, when the system detects overload, the driving arm can automatically contract to the shortest position, reducing the bending moment borne by the transmission mechanism. Compared with the fixed-arm structure, this telescopic design improves the adjustment accuracy of the counterweight system and reduces the impact loss of the mechanism.

[0044] Optionally, referring to Figure 3, the slideway 401 is a double-rail slideway, and each slider 402 is slidably engaged with the double rails of the slideway 401.

[0045] Specifically, four sets of ball circulation units are integrated at the bottom of each slider 402 to achieve an eight-point contact fit with the double rails. The slideway 401 adopts a double-rail structure design and forms a load-bearing sliding system with the slider 402. The double parallel rails form a stable rectangular force-bearing framework, which improves the rated load of the counterweight 5 and reduces the elastic deformation of the slideway 401 at the same time. The double-rail guidance effectively eliminates the yaw phenomenon during the movement of the slider 402. The double rails form a load-bearing path that is backed up by each other. When one side of the rail fails, the basic balance function can still be maintained through the remaining rails.

[0046] Optionally, refer to Figure 2 , a plurality of counterweights 5 are connected to each slider 402, and the plurality of counterweights 5 are connected by quick-release bolts.

[0047] With the design of connecting the plurality of counterweights 5 by quick-release bolts, in terms of adjustment, the quick-release bolts are used to complete the installation and removal of the counterweights 5 in a short time; the overall center of gravity after the superposition of the standardized interfaces of the counterweights 5 always coincides with the driving axis of the slider 402.

[0048] Optionally, refer to Figure 3 , buffer blocks 403 are provided at the center and the end of the slideway 401.

[0049] Specifically, the buffer block 403 is made of polyurethane elastomer, which can absorb the inertial impact kinetic energy during the normal operation of the slider 402 and effectively dissipate the remaining kinetic energy during emergency braking; the progressive compression characteristic of the buffer block 403 enables the slider 402 to stop smoothly at a predetermined position.

[0050] The above are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
