Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and in particular to an internal maintenance device for spherical buildings. Background Technology

[0002] With its high efficiency, the telescopic boom aerial work platform has been widely used in various high-altitude work scenarios such as building construction, power maintenance, and municipal maintenance. Its core function is to accurately transport the work platform to the designated height and position through the amplitude adjustment, length extension and 360° rotation of the telescopic boom to complete installation, maintenance and other operations.

[0003] However, when working inside spherical structures (such as domes, large storage tanks, planetarium domes, etc.), such devices face unique challenges: the interior space of a spherical structure is curved and shrinks, with the width of the passageway gradually narrowing from the bottom to the top; while the chassis of traditional straight-arm devices is usually designed to be wide to ensure stability, making it difficult to enter the work area through narrow passages. This results in problems such as difficulty in equipment access and incomplete work coverage for high-altitude operations inside spherical structures (such as interior wall maintenance and pipeline installation). Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an internal maintenance device for spherical buildings, which facilitates its fixation inside the spherical building.

[0005] This utility model provides an internal maintenance device for a spherical building, comprising a support base, a multi-stage telescopic boom, a working platform, a slewing mechanism, and a luffing mechanism. The support base is connected to the lower end of the multi-stage telescopic boom via the slewing mechanism, and the upper end of the multi-stage telescopic boom is connected to the working platform. The multi-stage telescopic boom and the slewing mechanism are connected via the luffing mechanism. The support base comprises a main support frame and connecting brackets. An outer annular rod is provided on the outer side of the main support frame, and a slewing support cylinder is fixedly installed on the main support frame. The center of the outer annular rod corresponds to the axis of the slewing support cylinder. Multiple connecting brackets are installed at the upper and lower ends of the main support frame, and annular slides are provided at the upper and lower ends of the outer annular rod. The connecting brackets are connected to arc-shaped sliders, which correspond to the annular slides and are placed within the annular slides of the outer annular rod, slidingly engaging with the annular slides. The connecting brackets are radially distributed along the diameter of the outer annular rod.

[0006] Furthermore, the slewing mechanism includes a hydraulic motor, a planetary reducer, and a slewing support cylinder. The hydraulic motor and the planetary reducer are installed inside the slewing support cylinder. The rotating shaft of the hydraulic motor is connected to the input shaft of the planetary reducer, and the output shaft of the planetary reducer is connected to the multi-stage telescopic boom.

[0007] Furthermore, the luffing mechanism is a first hydraulic cylinder, one end of which is hinged to the multi-stage telescopic boom, and the other end is hinged to the slewing mechanism.

[0008] Furthermore, the multi-stage telescopic boom is connected to the working platform and the leveling mechanism.

[0009] Furthermore, the leveling mechanism includes a connecting arm and a hydraulic cylinder. The upper end of the multi-stage telescopic arm is hinged to one end of the connecting arm, and the other end of the connecting arm is hinged to the working platform. The multi-stage telescopic arm and the connecting arm are connected by a second hydraulic cylinder, and the connecting arm and the working platform are connected by a third hydraulic cylinder.

[0010] Furthermore, the connecting bracket includes a connecting outer cylinder, a connecting inner rod, and a connecting seat. An arc-shaped slider is fixedly installed on the outer wall of the connecting outer cylinder. The connecting outer cylinder has a guide cavity with an outer end opening. The inner end of the connecting inner rod is inserted into the guide cavity of the connecting outer cylinder, and the outer end is connected to the connecting seat. The connecting seat is fixedly connected to the frame of the spherical building by bolts and nuts.

[0011] Furthermore, the connecting outer cylinder and the connecting inner rod are connected by a fourth hydraulic cylinder, which can drive the connecting inner rod to move along the guide cavity of the connecting outer cylinder.

[0012] Furthermore, the outer annular rod of the main support frame has an inner annular rod at its inner end. The outer and inner annular rods are arranged coaxially, and the inner annular rod has multiple positioning through holes evenly distributed in a circular shape. The connecting outer cylinder has two connecting through holes, which are located at the inner and outer ends of the outer annular rod, respectively. The fixing bolts pass through the connecting through holes at the outer ends of the two connecting outer cylinders located at the upper and lower ends of the main support frame and cooperate with the fixing nuts. The positioning bolts pass through the connecting through holes at the inner ends of the two connecting outer cylinders located at the upper and lower ends of the main support frame and the positioning through holes of the inner annular rod and cooperate with the positioning nuts, so that the two connecting outer cylinders are fixed on the main support frame.

[0013] Compared with the prior art, the present invention has the following outstanding advantages: Because the connecting brackets are always radially distributed along the diameter of the outer annular rod, this invention ensures that the axis of the slewing support cylinder precisely aligns with the center of the spherical structure, thereby aligning the rotation axis of the slewing mechanism with the center of the sphere. In this state, the multi-stage telescopic boom can always rotate around the central axis of the spherical structure. Therefore, when workers are operating on the spherical surface at the same height, there is no need to frequently adjust the length and amplitude of the multi-stage telescopic boom; the entire spherical working area at that height can be covered through rotational movement.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-3 As shown, this utility model includes a support base frame 1, a multi-stage telescopic boom 4, a working platform 6, a slewing mechanism 2, and a luffing mechanism 3.

[0017] The supporting base frame 1 is connected to the lower end of the multi-stage telescopic arm 4 via the slewing mechanism 2, and the upper end of the multi-stage telescopic arm 4 is connected to the working platform 6.

[0018] The multi-stage telescopic arm 4 and the slewing mechanism 2 are existing devices.

[0019] In this embodiment, the multi-stage telescopic boom 4 is a seven-section telescopic boom of XCMG GKS55A; the slewing mechanism 2 includes a hydraulic motor, a planetary reducer and a slewing support cylinder. The hydraulic motor and the planetary reducer are installed inside the slewing support cylinder. The rotating shaft of the hydraulic motor is connected to the input shaft of the planetary reducer, and the output shaft of the planetary reducer is connected to the multi-stage telescopic boom 4.

[0020] The multi-stage telescopic boom 4 and the slewing mechanism 2 are connected by a luffing mechanism 3. The luffing mechanism 3 is a first hydraulic cylinder, one end of which is hinged to the multi-stage telescopic boom 4 and the other end of which is hinged to the slewing mechanism 2.

[0021] The multi-stage telescopic arm 4 is connected to the working platform 6 and the leveling mechanism 5. The leveling mechanism 5 is an existing device. In this embodiment, the leveling mechanism 5 includes a connecting arm and a hydraulic cylinder. The upper end of the multi-stage telescopic arm 4 is hinged to one end of the connecting arm, and the other end of the connecting arm is hinged to the working platform 6. The multi-stage telescopic arm 4 and the connecting arm are connected by a second hydraulic cylinder, and the connecting arm and the working platform 6 are connected by a third hydraulic cylinder.

[0022] The supporting base frame 1 includes a main support frame 11 and a connecting bracket 12. An outer ring rod 112 is provided on the outer side of the main support frame 11. A slewing bearing cylinder is fixedly installed on the main support frame 11. The center of the outer ring rod 112 corresponds to the axis of the slewing bearing cylinder.

[0023] Multiple connecting brackets 12 are installed at the upper and lower ends of the main support frame 11, and multiple telescopic legs are vertically installed at the lower end of the main support frame 11.

[0024] The outer annular rod 112 has annular slides at its upper and lower ends. The connecting bracket 12 is connected to the arc-shaped slider. The arc-shaped slider corresponds to the annular slide and is placed in the annular slide of the outer annular rod 112, sliding with the annular slide. During the sliding process, the connecting bracket 12 can always be radially distributed along the diameter direction of the outer annular rod 112.

[0025] The connecting bracket 12 includes a connecting outer cylinder 123, a connecting inner rod 122, and a connecting seat 121. An arc-shaped slider is fixedly installed on the outer wall of the connecting outer cylinder 123. The connecting outer cylinder 123 is provided with a guide cavity with an outer end opening. The inner end of the connecting inner rod 122 is inserted into the guide cavity of the connecting outer cylinder 123, and the outer end is connected to the connecting seat 121. The connecting seat 121 is fixedly connected to the frame of the spherical building by bolts and nuts.

[0026] In the optimized scheme, the connecting outer cylinder 123 and the connecting inner rod 122 are connected by a fourth hydraulic cylinder, which can drive the connecting inner rod 122 to move along the guide cavity of the connecting outer cylinder 123.

[0027] The inner end of the outer annular rod 112 of the main support frame 11 is provided with an inner annular rod 111. The outer annular rod 112 and the inner annular rod 111 are arranged coaxially, and the inner annular rod 111 is provided with a plurality of positioning through holes evenly distributed in a circular shape.

[0028] The connecting outer cylinder 123 is provided with two connecting through holes, which are located at the inner and outer ends of the outer annular rod 112 respectively. The fixing bolt 124 passes through the connecting through holes at the outer ends of the two connecting outer cylinders 123 located at the upper and lower ends of the main support frame 11 and cooperates with the fixing nut 125. The positioning bolt 126 passes through the connecting through holes at the inner ends of the two connecting outer cylinders 123 located at the upper and lower ends of the main support frame 11 and the positioning through hole of the inner annular rod 111 and cooperates with the positioning nut 127, so that the two connecting outer cylinders 123 are fixed on the main support frame 11.

[0029] The hydraulic motor and hydraulic cylinder are driven by a hydraulic power system, which is existing technology and its specific structure will not be described in detail.

[0030] The operation process is as follows: When using this utility model, first adjust the connecting brackets 12 around the main support frame 11 to the same elongation, rotate the connecting brackets 12 to the appropriate position, so that the fixing bolts 124 pass through the connecting through holes at the outer ends of the two connecting outer cylinders 123 located at the upper and lower ends of the main support frame 11 and cooperate with the fixing nuts 125. The positioning bolts 126 pass through the connecting through holes at the inner ends of the two connecting outer cylinders 123 located at the upper and lower ends of the main support frame 11 and the positioning through hole of the inner ring rod 111 and cooperate with the positioning nuts 127, so that the connecting brackets 12 are fixed on the main support frame 11, and then fixedly connected to the frame structure of the spherical building by bolt and nut assembly. Since each connecting bracket 12 is always radially distributed along the diameter direction of the outer ring rod 112, it can ensure that the axis of the slewing support cylinder is precisely aligned with the center of the spherical building, thereby making the rotation axis of the slewing mechanism 2 coincide with the center of the sphere. In this state, the multi-stage telescopic boom 4 can always rotate around the central axis of the spherical structure. Therefore, when workers are working on the spherical area at the same height, they do not need to frequently adjust the length and amplitude of the multi-stage telescopic boom 4. The entire spherical working range at that height can be covered by the rotational motion.

[0031] The slewing mechanism 2 can drive the multi-stage telescopic boom 4 to achieve 360° full-circle rotation, the luffing mechanism 3 can flexibly adjust the pitch angle of the multi-stage telescopic boom 4, and the telescopic function of the multi-stage telescopic boom 4 itself can precisely adjust the spatial position of the work platform 6. The three work together to achieve full coverage of the work platform 6 inside the spherical building.

[0032] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
