[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present invention and its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments herein. In the present invention, when a particular device is described as being between a first device and a second device, there may or may not be an intermediate device between the particular device and the first device or the second device. Example

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a steel tube bundle core tube liftable operating platform, including an operating platform 11, a lifting mechanism, an anti-falling mechanism and a controller.

[0030] The bottom frame of the operating platform 11 is surrounded by a frame extending upward, and the frames at both ends in the longitudinal direction are respectively provided with fixed hanging plates 12, and each of the fixed hanging plates 12 is detachably connected to the ear seats 41, 42, 43 of the steel tube bundle core tube.

[0031] The lifting mechanism is symmetrically arranged at both ends of the operating platform 11 in the longitudinal direction, and is respectively provided with a winch 24 connected to the motor 22. The controller is connected to each motor 22 to drive the corresponding winch 24 to rotate at a constant speed. The hanging rope 21 of the winch 24 is extended to the same length and connected to the movable hanging plate 23, and the movable hanging plate 23 is detachably connected to the ear seats 41, 42, 43 of the steel tube bundle core tube. Preferably, the main shaft of the winch 24 is connected to a normally closed brake, and the controller is connected to the normally closed brake.

[0032] Each of the fixed hanging plates 12 is provided with a hanging hole, which is adapted to the ear seat positioning hole of the steel tube bundle core tube, and the hanging hole and the positioning hole are connected by a detachable locking pin. The width of the movable hanging plate 23 is equal to the spacing between the two fixed hanging plates 12 arranged opposite to each other in the transverse direction, and the two ends of the movable hanging plate 23 are respectively provided with hanging holes adapted to the ear seat positioning holes of the steel tube bundle core tube, and the hanging holes and the positioning holes are connected by a detachable locking pin. Further, the fixed hanging plates 12 are symmetrically arranged in two groups along the width direction of the operating platform 11, and the hanging rope 21 of the winch 24 is centrally arranged between the two fixed hanging plates 12.

[0033] like Figure 4 and Figure 5 As shown, the provided pushing roller 31 is pressed against the inner wall of the steel tube bundle core tube for lifting:

[0034] First, the first ear seat 41, the second ear seat 42 and the third ear seat 43 are welded in sequence from bottom to top on the inner wall of the steel tube bundle core tube.

[0035] Then, the fixed hanging plate 12 of the operating platform 11 is fixedly connected to the first ear seat 41 through a locking pin, and construction is performed at the height of the first ear seat 41;

[0036] Then, when lifting is required, the movable hanging plate 23 at the front end of the hanging rope is fixedly connected to the third ear seat 43 through a locking pin, and the locking pin between the fixed hanging plate 12 and the first ear seat 41 is removed;

[0037] Then, the controller drives the winch 24 to rotate, drives the hanging rope 21 to be wound up, drives the operating platform 11 to rise to the second ear seat 42, and fixes the fixed hanging plate 12 to the second ear seat 42 through the locking pin;

[0038] When further elevation is required, the movable hanging plate 23 is connected to the upper ear seat to achieve step-by-step elevation of the operating platform.

[0039] The provided steel tube bundle core tube liftable operating platform combines the connection and disconnection operations between the fixed hanging plate, the movable hanging plate and the ear seat of the steel tube bundle core tube. The motor of the lifting mechanism drives the winch, and the step-by-step lifting and lowering of the operating platform is achieved by winding and releasing the steel rope. The process is smooth and reliable, and the operation is simple. It is suitable for construction at different heights in the steel tube bundle core tube. Example

[0040] Furthermore, the anti-fall mechanism is symmetrically arranged at both ends of the operating platform 11 in the longitudinal direction, including a roller 31 supported on the inner wall of the steel tube bundle core tube, and the wheel axle of the roller 31 is connected to the reverse brake. In a specific implementation, the rim surface of the roller 31 is covered with an elastic rubber layer, which can realize the vibration reduction function during the lifting process and can also increase the friction resistance during the braking process. The anti-fall mechanism also includes a support cylinder 32, the movable rod of the support cylinder 32 extends longitudinally, the roller 31 is connected to the front end of the movable rod, and the controller is connected to the support cylinder 32.

[0041] The roller of the anti-fall mechanism is connected to the reverse brake, and the roller 31 is supported to the inner wall of the steel tube bundle core tube through a telescopic and adjustable support cylinder 32, which can play a braking and buffering role when the operating platform falls, prevent free fall motion, and improve the safety of construction operations on the operating platform. Example

[0042] Furthermore, the structure of the anti-fall mechanism is further optimized on the basis of the second embodiment:

[0043] An elastic support member is provided between the movable rod and the roller 31. When the movable rod of the support cylinder 32 is in a retracted state, the roller 31 is supported to the inner wall of the steel tube bundle core tube by the elastic support member.

[0044] During the normal lifting movement of the operating platform, the lifting speed is stably maintained within the set range. The controller does not drive the movable rod of the support cylinder 32 to extend, but only supports the roller to the inner wall of the steel tube bundle core tube through the elastic support member, thereby playing a supporting role, preventing the operating platform from shaking and maintaining the stability of the lifting process.

[0045] The winch 24 is connected to a speed sensor, and the controller is connected to the speed sensor signal, and is configured to receive and control the action of the support cylinder 32 according to the speed monitoring information of the speed sensor, and to control the active rod of the support cylinder 32 to extend when the speed is higher than the set value, pushing the roller 31 to press against the inner wall of the steel tube bundle core tube.

[0046] When the operating platform falls, the speed information monitored by the speed sensor is transmitted to the bucket controller. The controller determines that the falling problem occurs and promptly drives the movable rod of the support cylinder 32 to extend. The roller 31 is pressed tightly to push the roller 31 to the inner wall of the steel pipe bundle core tube. The reverse brake prevents the roller 31 from rotating. The roller 31 replaces the rolling support with static friction to decelerate and buffer the fall of the operating platform 11, prevent the occurrence of free fall, and improve the safety of construction on the operating platform 11.
