Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hanging basket construction, in particular to a variable cross-section hanging basket construction safety protection device. BACKGROUND

[0002] The variable cross-section hanging basket construction method is often used in bridge construction, and the existing hanging baskets are mostly hoisted by steel cables. During the bridge construction process, the hanging baskets are in a suspended state, and the crosswind at the bridge is large. Therefore, the hanging baskets are prone to shaking during use.

[0003] To this end, Chinese Patent Application No. 201910674983.X discloses a protection device for a hanging basket used in road and bridge construction. The device mainly drives the worm gear to rotate by means of a servo motor, drives the worm wheel to rotate, drives the gear to rotate by means of a second transmission member, and drives the gear to rise and fall along the hanging beam under the action of the rack. The device is safe and reliable, effectively avoids the shaking of the hanging basket caused by crosswind, overcomes the risk of falling of the hanging basket by means of the one-way transmission worm and gear structure, and sets a manual locking device at the upper part of the hanging basket to prevent the hanging basket from shaking in the case of failure of the air cylinder or servo motor, thereby greatly improving the safety and stability of the hanging basket.

[0004] However, the present inventors have found at least the following technical problems in the process of implementing the technical solutions in the embodiments of the present application:

[0005] The gear and the rack are engaged by means of the rotational connection of the swing beam, so the swing beam needs to be constantly pushed by the air cylinder, otherwise it will disengage. Therefore, a manual locking device is additionally provided to serve as an insurance, resulting in a complex structure. INVENTION CONTENTS

[0006] To make up for the above shortcomings, the present application provides a variable cross-section hanging basket construction safety protection device, which aims to improve the problems mentioned in the background art.

[0007] The present application provides a variable cross-section hanging basket construction safety protection device, which includes a cross beam and a channel steel. The cross beam is fixedly connected with a hanging basket at the lower side, and is provided with a lifting ring at the upper side. The cross beam is telescopically connected with cantilevers at both sides. The cantilevers are provided with rolling mechanisms at the outer ends. The rolling mechanisms are located between the inner side walls of the channel steel. The cross beam is provided with a driving mechanism in the middle. The driving mechanism is connected with the rolling mechanisms at both sides through shafts.

[0008] In a specific embodiment, the rolling mechanism includes a wheel carrier, which is rotatably connected with a gear and a roller at both sides, respectively. The channel steel is fixedly connected with a rack, which is engaged with the gear. The roller is rollingly connected with the inner wall of the channel steel.

[0009] In the implementation process, when the rolling mechanism rolls inside the channel steel, the gear rolls along the rack, and the roller rolls along the channel steel, so that the gear and the roller can be clamped in the channel steel and remain in close contact without being separated.

[0010] In a specific embodiment, two rollers are arranged on each wheel carrier, and the two rollers and the gear are in a triangular distribution.

[0011] In the implementation process, the triangular distribution allows the roller structure to be clamped in the channel steel, and the gear and the rack will not be separated due to the swinging of the basket.

[0012] In a specific embodiment, a clamping block is screwed on the cantilever, the clamping block abuts the cross beam, and a sheep horn screw is screwed on the clamping block.

[0013] In the implementation process, by tightening the sheep horn screw, the clamping block is tightly abutted on the cross beam, thereby locking the current posture of the cantilever, and the adjustment is convenient.

[0014] In a specific embodiment, the clamping block and the cross beam are provided with teeth at the abutting position.

[0015] In the implementation process, after the clamping block is tightly abutted on the cross beam, the teeth are engaged with each other to provide more resistance and improve the fixing force between the cross beam and the cantilever.

[0016] In a specific embodiment, the driving mechanism includes a prism rod and a prism sleeve, the prism rod is connected with the prism sleeve in an extension and retraction manner, the prism sleeve is rotationally connected with the cross beam, and one end of the prism rod is fixedly connected with the gear.

[0017] In the implementation process, the prism rod is connected with the prism sleeve in an extension and retraction manner and remains in axial connection, thereby achieving the effect of extension and retraction transmission, i.e., the rolling mechanisms on both sides remain in axial connection during extension and retraction.

[0018] In a specific embodiment, the driving mechanism further includes a motor, the motor is installed on the cross beam, and an output end of the motor is axially connected with the prism sleeve.

[0019] In the implementation process, the motor drives the rotation of the prism sleeve, and the rotation of the prism sleeve drives the rotation of the rolling mechanisms on both sides through the cooperation of the prism sleeve and the prism rod. In this embodiment, the motor is provided with double shafts, one output end of the motor is axially connected with the prism sleeve, and the other output end of the motor is provided with an interface, which can be externally connected with a hand wheel or a hand drill, etc. When the motor cannot work normally, the prism sleeve is driven in a manual manner.

[0020] In a specific embodiment, the driving mechanism further includes a worm gear and a worm, the worm gear is fixedly connected with the prism sleeve, the worm is engaged with the worm gear, and the worm is fixedly connected with an output end of the motor.

[0021] In the above implementation process, the worm gear and the worm play the role of speed reduction and torque increase, and the self-locking effect is also used to avoid the basket from falling. Since the gear is kept in the channel steel, as long as the rotation of the gear is locked, the effect of safety lock can be achieved.

[0022] Compared with the prior art, the beneficial effects of the present application are that the cantilever is horizontally pushed out, the rolling mechanism is inserted into the inner side of the channel steel, the connection with the channel steel is achieved, since the rolling mechanism is located between the inner side walls of the channel steel, the support of the channel steel can be obtained without being easily loosened, and thus the height locking can be achieved by using the shaft connection of the driving mechanism and the rolling mechanism, without the need for additional locking devices, and the structure is simplified.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described below in combination with the drawings in the embodiments of the present application.

[0030] Please refer to Figures 1-4 ​The application provides a variable cross-section hanging basket construction safety protection device, which comprises a cross beam 10 and a channel steel 20, the lower side of the cross beam 10 is fixedly connected with a hanging basket 30, the upper side of the cross beam 10 is provided with a lifting ring 40, the two sides of the cross beam 10 are telescopically connected with cantilevers 50, the outer ends of the cantilevers 50 are provided with rolling mechanisms 60, the rolling mechanisms 60 are located between the inner side walls of the channel steel 20, a driving mechanism 70 is arranged in the cross beam 10, and the driving mechanism 70 is axially connected with the rolling mechanisms 60 on the two sides. Wherein, the cantilevers 50 are horizontally pushed outwards, the rolling mechanisms 60 are inserted into the channel steel 20, the connection with the channel steel 20 is realized, the rolling mechanisms 60 are located between the inner side walls of the channel steel 20, the support of the channel steel 20 can be obtained and the rolling mechanisms 60 cannot be easily loosened, the height locking can be realized by the axial connection of the driving mechanism 70 and the rolling mechanisms 60, and no additional locking device is needed, so that the structure is simplified.

[0031] Please refer to Figures 1-4 The rolling mechanism 60 comprises a wheel frame 61, gear wheels 62 and rollers 63 which are rotatably connected to the two sides of the wheel frame 61 respectively, a rack 64 which is fixedly connected to the inner wall of the channel steel 20 and is engaged with the gear wheels 62, and the rollers 63 which are rollingly connected with the inner wall of the channel steel 20. When the rolling mechanism 60 rolls in the inner side of the channel steel 20, the gear wheels 62 roll along the rack 64, and the rollers 63 roll along the channel steel 20, so that the gear wheels 62 and the rollers 63 can be clamped in the channel steel 20 and cannot be separated.

[0032] Please refer to Figures 1-4 Two rollers 63 are arranged on each wheel frame 61, and the two rollers 63 and the gear wheels 62 are distributed in a triangular shape. The triangular distribution makes the rollers 63 clamped in the channel steel 20, and the gear wheels 62 cannot be separated from the rack 64 due to the swing of the hanging basket 30.

[0033] Please refer to Figures 1-4 The cantilevers 50 are screwed with clamping blocks 51, the clamping blocks 51 abut against the cross beam 10, and the clamping blocks 51 are screwed with gooseneck screws 52. By tightening the gooseneck screws 52, the clamping blocks 51 are tightly abutted against the cross beam 10, so that the current posture of the cantilevers 50 is locked, and the adjustment is convenient.

[0034] Please refer to Figures 1-4 The clamping blocks 51 and the cross beam 10 are provided with teeth at the abutting positions. After the clamping blocks 51 are tightly abutted against the cross beam 10, the teeth are engaged with each other, more resistance is provided, and the fixing force between the cross beam 10 and the cantilevers 50 is improved.

[0035] Please refer to Figures 1-4 The driving mechanism 70 comprises a prismatic rod 71 and a prismatic sleeve 72, the prismatic rod 71 is telescopically connected with the prismatic sleeve 72, the prismatic sleeve 72 is rotatably connected with the cross beam 10, and one end of the prismatic rod 71 is fixedly connected with the gear wheel 62. The prismatic rod 71 is telescopically connected in the prismatic sleeve 72 and is axially connected, and has the effect of telescopic transmission, that is, the rolling mechanisms 60 on the two sides still remain axially connected when being telescopically connected.

[0036] Please refer to Figures 1-4 The driving mechanism 70 further comprises a motor 73 mounted on the cross beam 10, and the output end of the motor 73 is connected with the shaft of the prism sleeve 72. The motor 73 drives the prism sleeve 72 to rotate, and drives the two rolling mechanisms 60 to rotate through the cooperation of the prism sleeve 72 and the prism rod 71. In the embodiment, the motor 73 is provided with double shafts, one output end of the motor 73 is connected with the shaft of the prism sleeve 72, and the other output end of the motor 73 is provided with an interface, which can be externally connected with a hand wheel or a hand drill, etc. When the motor 73 cannot work normally, the prism sleeve 72 is driven to rotate in a manual mode.

[0037] Please refer to Figures 1-4 The driving mechanism 70 further comprises a worm gear 74 and a worm 75, the worm gear 74 is fixedly connected with the prism sleeve 72, the worm 75 is engaged with the worm gear 74, and the worm 75 is fixedly connected with the output end of the motor 73. The worm gear 74 and the worm 75 play a role of speed reduction and torque increase, and also utilize the self-locking effect to avoid the basket 30 from falling. Since the gear 62 is kept in the channel steel 20, as long as the rotation of the gear 62 is locked, the effect of safety lock can be achieved.

[0038] The working principle of the variable cross-section hanging basket construction safety protection device is as follows: the channel steel 20 is hoisted on the bridge body, the lifting ring 40 is connected with the cable, so that the basket 30 is in a suspended state. When there is no wind, the basket 30 is naturally suspended. When the wind blows, the two cantilevers 50 are manually pushed outwards, the rolling mechanism 60 is inserted into the two channel steels 20, then the wing nuts 52 are rotated to make the clamping blocks 51 abut against the cross beam 10, so that the locking is achieved. When lifting, the motor 73 drives the prism sleeve 72 to rotate through the engagement of the worm gear 74 and the worm 75, and then drives the prism rod 71 and the gear 62 to rotate, and the posture locking is achieved through the self-locking effect of the worm gear 74 and the worm 75. When the motor 73 fails, the hand wheel can be externally connected to achieve the effect of manual lifting. In summary, the cantilevers 50 are horizontally pushed outwards, the rolling mechanism 60 is inserted into the inside of the channel steel 20 to achieve the connection with the channel steel 20. Since the rolling mechanism 60 is located between the inside walls of the channel steel 20, it can be supported by the channel steel 20 and will not easily fall off. Therefore, the height locking can be achieved through the shaft connection of the driving mechanism 70 and the rolling mechanism 60, without the need to additionally set a locking device, thereby simplifying the structure.
