Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction basket, in particular to a construction basket with anti-high-altitude falling structure. BACKGROUND

[0002] With the acceleration of urbanization, the traditional scaffold relied on by early high-rise building construction has long construction period, large material consumption and is limited by building shape, which cannot meet the operation needs of complex structure of super high-rise building. In order to solve the contradiction between high-altitude operation efficiency and safety, the construction basket is born with the characteristics of light weight, modular design and lifting adjustment, and gradually becomes the mainstream equipment for high-altitude operation such as external wall decoration, curtain wall installation and cleaning and maintenance, and is widely used in various super high-rise building projects. The main body of the basket is composed of a suspension platform, a suspension mechanism, a lifting machine and a safety device. The suspension mechanism is fixed on the bearing structure at the top of the building, and the suspension platform below is connected through a steel wire rope. The lifting machine is a power device, which drives the gear or drum to rotate by using a motor, drives the steel wire rope to be wound or unwound, realizes the lifting of the suspension platform, and the safety lock is the core protection component. When the platform descends at a speed exceeding the set value or the inclination angle exceeds the set value, the steel wire rope will be automatically locked to prevent falling.

[0003] The existing construction basket often appears slight inclination of the platform in actual operation due to material stacking deviation, personnel walking and the like. Although the inclination does not trigger the safety lock protection mechanism, it will cause uneven operation surface, increase the risk of tool falling, interfere with the operation accuracy of personnel and reduce the construction efficiency. The traditional solution relies on manual operation of the operator to control the lifting machine on both sides through the operation panel and adjust the length of the steel wire rope to correct the level according to experience. This method occupies operation time, easily distracts the attention of personnel and has safety hazards.

[0004] In view of the above problems, it is urgent to make innovative design on the basis of the original. SUMMARY

[0005] The present application aims to provide a construction basket with anti-high-altitude falling structure to solve the problem of slight inclination of the platform and the need for manual adjustment in the background art. The technical solution of the present application provides a solution significantly different from the prior art to solve the technical problem that the prior art solution is too single.

[0006] In order to achieve the above object, the present application provides the following technical scheme: a construction hanging basket with high-altitude falling prevention structure, comprising a suspension platform, a main rope, a secondary rope and a safety lock, the suspension platform is provided with the safety lock on both sides, a swing arm is rotatably installed on the top of the safety lock, the main rope passes through the swing arm, the secondary rope passes through the safety lock, a limiting rod is rotatably installed at the bottom of the swing arm, a limiting block is fixed at the bottom end of the limiting rod, two adjusting seats are symmetrically installed inside the suspension platform, an auxiliary winding drum set is rotatably installed inside the adjusting seat, a rotating rod is rotatably installed inside the adjusting seat, a balance assembly is arranged on the surface of the rotating rod, a balance rod is rotatably installed at the bottom of the suspension platform, a locking seat is fixed on the two side walls of the suspension platform, a locking assembly is arranged inside the locking seat, two electric push rods are installed at the bottom of the suspension platform, and the two electric push rods are respectively connected with both ends of the balance rod; The locking assembly comprises an extrusion groove formed in the locking seat, a plurality of locking blocks are limitingly and slidably installed inside the locking seat, a moving block is fixed on the side wall of the locking block, a spring is fixed at the bottom end of the locking block, and the locking block is connected with the locking seat through the spring.

[0007] Preferably, the limiting block is slidably installed inside the locking seat, a protrusion is fixed at the top end of the limiting block, and the side wall of the limiting block is in close contact with the protrusion.

[0008] Preferably, the extrusion groove is designed to be inclined, and the moving block is located on the inner wall of the extrusion groove.

[0009] Preferably, the balance assembly comprises a connecting shaft fixed at the center position of the rotating rod, a driven gear is fixed at one end of the connecting shaft, a belt is sleeved at the other end of the connecting shaft, two moving grooves are formed in the surface of the rotating rod, two moving wheels are slidably installed inside the adjusting seat, and a driving rod is vertically and limitingly slidably installed inside the adjusting seat.

[0010] Preferably, a plurality of one-way teeth are elastically connected to the top end of the driving rod, and the bottom of the one-way tooth is designed to be inclined.

[0011] Preferably, the connecting shaft is connected with the auxiliary winding drum set located below the rotating rod through the belt, and the driven gear is meshed with the one-way tooth.

[0012] Preferably, a limiting groove is formed in the adjusting seat, the moving wheel is located on the inner wall of the limiting groove, guide blocks are fixed on both sides of the moving wheel, and the guide blocks are located on the inner wall of the moving groove.

[0013] Preferably, two auxiliary winding drum sets are rotatably installed inside the adjusting seat, a motor is connected with the auxiliary winding drum set located below the adjusting seat, the main rope is slidably contacted in the auxiliary winding drum set, and the main rope is slidably contacted with the two moving wheels.

[0014] Preferably, the inner wall of the balance rod is provided with balance oil, and two driving rods are respectively slidably connected to the two ends of the balance rod.

[0015] Compared with the prior art, the present application has the following advantages: 1. The present application automatically corrects the slight inclination of the suspension platform during operation by setting the main rope, adjusting seat, rotating rod, balance rod and balance assembly. When the suspension platform inclines, the balance rod will rotate correspondingly with the inclination angle. The driving rod and the one-way tooth belt drive the driven gear to rotate synchronously, which promotes the synchronous operation of the rotating rod. Under the cooperation of the limiting groove and the moving groove, the two moving wheels move closer to each other, releasing the main rope. By adjusting the height of one side of the suspension platform, automatic leveling is achieved without manual intervention to respond to the inclination state in real time. This avoids the tediousness and time-consuming of manual adjustment, ensures the timeliness and accuracy of the adjustment action, effectively maintains the level of the working surface, reduces the operation interference caused by inclination, improves the construction efficiency, and reduces the safety risks that may be caused by manual operation.

[0016] 2. The present application further locks the steel wire rope by setting the locking seat, electric push rod and locking assembly, preventing the safety lock from wearing out due to long-term use, resulting in insufficient friction between the locking pawl and the steel wire rope, even if the locking is performed, the falling risk caused by the downward sliding still occurs. When the main rope breaks, the swing arm connected to the safety lock will rotate, triggering the action of the locking pawl inside the safety lock. At the same time, the swing arm will drive the limiting rod and the limiting block to move upward, thereby releasing the limiting of the locking block. The locking block moves rapidly under the pushing force of the spring, forming extrusion on the auxiliary rope. If the auxiliary rope still appears downward sliding phenomenon after locking, the locking block will gradually increase the extrusion force on the auxiliary rope under the cooperation of the extrusion groove and the moving block, adding more reliable safety protection for the hanging basket operation.
