Description

Technical Field

[0001] The utility model relates to the technical field of construction platforms, and particularly relates to an intelligent self-adjusting construction platform. Background Technique

[0002] The scissor lift construction platform is a common aerial work equipment, which realizes the lifting function of the platform through a scissor structure. The lifting mechanism of this equipment consists of multiple hinged support rods (usually arranged in a cross pattern), and is driven by a hydraulic system or an electric motor. The scissor structure can stretch vertically, thereby raising or lowering the platform height.

[0003] During the use of the existing construction platform, due to a large number of hinge points in the scissor structure, affected by installation and usage time, there will be a certain mechanical margin left for the support shaft and the hinge. And after a long time of use, the wear at the connecting shaft will cause a certain amount of play between each hinge rod. Exactly because in order to meet the height requirement, multiple sets of single-group X-shaped support structures of the scissor structure are set. Therefore, there will be at least 3 hinge points between adjacent two sets of support structures. When there is a margin at each hinge point, plus the product of the margins of multiple hinge points, when the top center of gravity is unbalanced, there will be a situation where the axis in the overall vertical direction deflects left and right or front and back. Therefore, it will cause the problem of overall imbalance of the equipment due to the change of the top center of gravity during the lifting of the platform. Especially during aerial work, this unbalanced state poses a great threat to the safety of construction. In order to ensure the stability of the construction platform during the lifting process, the prior art usually relies on manual operation of counterweights or other mechanical adjustment means to keep the platform balanced. However, this manual adjustment method not only has low efficiency, but also has disadvantages such as slow response time and large error, and cannot adapt to complex construction environments. Especially when the platform needs to be lifted frequently or when the unbalanced load is large, the traditional adjustment method is difficult to ensure the real-time balance of the platform. Therefore, there is an urgent need for a technology that can automatically sense the change of the platform center of gravity and adjust the counterweight in real time, so as to improve the safety and operation efficiency of the construction platform. In view of the above problems, an intelligent self-adjusting construction platform is specifically proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-12 , the present utility model provides a technical solution: an intelligent self-adjusting construction platform, including a lifting platform 1. The lifting platform 1 includes a base 11 capable of traveling. The top of the base 11 is equipped with a lifting mechanism. The top of the lifting mechanism is equipped with a self-adjusting mechanism 2. The top of the self-adjusting mechanism 2 is equipped with a carrying bucket 16; The self-adjusting mechanism 2 includes a housing 21. Inside the housing 21, a guide rail 1 24 is assembled. Inside the guide rail 1 24, a slide block 1 25 is slidably assembled. Inside the slide block 1 25, a guide rail 2 26 is assembled. Inside the guide rail 2 26, a slide block 2 27 is assembled. The bottom end of the slide block 2 27 is equipped with a counterweight 28; The top of the housing 21 is equipped with a cover plate 22. At the center of the cover plate 22, a detection device 3 is assembled; The detection device 3 includes a shell 31. The top of the shell 31 is rotatably assembled with a swivel ring 32. Inside the swivel ring 32, a rotating shaft 33 is rotatably assembled. In the middle of the rotating shaft 33, a gravity pendulum 34 is screwed. Angle sensors for measuring angles are assembled at the hinge between the swivel ring 32 and the shell 31 and at the hinge between the rotating shaft 33 and the swivel ring 32.

[0030] The utility model provides an intelligent self-adjusting construction platform with a function of automatically detecting the balance degree of a personnel carrier bucket on the construction platform and automatically adjusting it. When in use, the internal equipment of the platform 11 drives the hydraulic cylinder 15 to extend and retract, thereby driving the change of the horizontal cross distance between the articulated rods 13 to control the change of the vertical direction of the articulated rods 13, and then driving the carrier bucket 16 to lift. During the whole process of lifting and use, when the length of the carrier bucket 16 changes or the imbalance of the carrier bucket 16 is caused by other factors such as transportation tools and goods, the double-angle data output by the detection device 3 is transmitted to the control module, and the control module controls the position change of the counterweight 28 to re-drive the carrier bucket 16 to be balanced, ensuring the safety of the operation of the construction platform, and effectively solving the impact on the overall safety of the equipment caused by the change of the top center of gravity when the existing construction platform is operating at a high altitude.

[0031] Specifically, a traveling mechanism 12 is assembled at the bottom of the platform 11, and a telescopic auxiliary support mechanism is assembled on the side of the platform 11. The inside of the platform 11 is provided with a hydraulic station and a controller, and the controller can control the hydraulic station to inject or extract hydraulic oil into the hydraulic cylinder 15, thereby driving the articulated change of the articulated rods 13 and finally achieving the purpose of lifting.

[0032] Specifically, the lifting mechanism includes cross-articulated articulated rods 13. The inner side of the bottom end of the articulated rods 13 is assembled with a hydraulic cylinder 15. The top and bottom outer sides of the lifting mechanism are assembled with driven mechanisms, and the driven mechanisms can displace in the horizontal direction.

[0033] Specifically, a base 14 is assembled between the lifting mechanism and the self-adjusting mechanism 2. The base 14 includes an edge protection frame and a hinge point, and the protection frame and the hinge point forming the base 14 are welded on the lower surface of the housing 21.

[0034] Specifically, a telescopic frame is assembled on the side of the carrier bucket 16. The telescopic end frame mechanism is preferably adjusted by a mechanical structure, and the length of the carrier bucket 16 can be lengthened after adjustment, increasing the carrying area and width of the carrier bucket 6.

[0035] Specifically, plugs are assembled on the outer sides of the guide rail 1 24 and the guide rail 2 26. A stepping motor is assembled on the outer side of the plug on either side of the guide rail 1 24 and the guide rail 2 26. The output end of the stepping motor is assembled with a lead screw transmission mechanism, and the lead screw transmission mechanism can drive the displacement of the slider 1 25 or the slider 2 27, so as to drive the displacement of the guide rail 2 26 through the displacement of the slider 1 25, and the guide rail 2 26 drives the displacement of the slider 2 27, and finally achieves the purpose of driving the displacement of the counterweight 28.

[0036] Specifically, two sets of guide rail 1 (24) and two sets of guide rail 2 (26) are used. Guide rail 1 (24) and guide rail 2 (26) are arranged oppositely. Four slider 1 (25) are used and two slider 2 are used. Through the symmetrically paired and complete set of guide rail and slider structures, the counterweight 28 can be positioned synchronously in two directions to ensure the stability during normal use.

[0037] Specifically, the axis of the hinge position between the swivel ring 32 and the housing 31 and the axis of the rotating shaft 33 are perpendicular to each other, and the two axes are respectively parallel to the edge of the outer shell 21. Therefore, the detection device 3 is dedicated to converting the unbalance value of the bottom support surface of the transport bucket 16 into the detection of the angular offsets in two mutually perpendicular directions along the vertical axis in the direction of gravity, so as to obtain the final offset angle data through the detection of the included angles between the x-axis and y-axis directions of the bearing plane of the transport bucket 16 and the vertical z-axis when viewed from above.

[0038] Specifically, a control module is assembled inside the self-adjusting mechanism 2. The control module is connected to the angle sensor to obtain the included angle between the horizontal plane of the swivel ring 32 and the horizontal cross-section of the housing 31 and the included angle value between the initial plane of the rotating shaft 33 and the horizontal cross-section of the housing 31. After calculating the data, the control module converts the angle value into proportional data through a control logic algorithm, and converts it into a displacement distance of an appropriate length according to the stroke lengths of guide rail 1 (24) and guide rail 2 (26), and finally moves the counterweight 28 in the reverse direction to balance the levelness of the transport bucket 16.

[0039] For example, taking the central axis of guide rail 2 (26) as the x-axis direction and the central axis of guide rail 1 (24) as the y-axis direction,

[0040] The setting of the automatic adjustment program lies in that the measured angles have a vector relationship.

[0041] The types of measured angles include:

[0042] ①. The included angle between the x-axis and the z-axis;

[0043] ②. The included angle between the -x axis and the z-axis;

[0044] ③. The included angle between the y-axis and the z-axis;

[0045] ④. The included angle between the -y axis and the z-axis.

[0046] There are a total of four angle measurement results, and according to the positive and negative of the x-axis and y-axis, the angles are also correspondingly recorded as positive and negative. For example, when the included angle between the platform in the x direction and the z-axis is 3°, it is recorded as 3° (x), and when the included angle between the platform in the -x direction and the z-axis is 3°, it is recorded as -3° (x);

[0047] Based on the results of the above measurements, when the angle between the platform and the z-axis in the x direction is 3°, the slider is controlled to move a fixed distance in the -x direction (this distance is related to the total length of the guide rail).

[0048] Through the above automatic adjustment method, when the angle reaches the dangerous range value, the control module automatically adjusts it, so as to ensure that within the range that needs to be controlled, the platform is trimmed and corrected at an appropriate frequency, and finally the purpose of automatically maintaining the balance of the carrier platform is achieved.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
