Description

Technical Field

[0001] This utility model relates to the field of stage vehicle equipment technology, and in particular to a cross-frame type roof lifting device with a lifting height of 6-9 meters. Background Technology

[0002] In the field of stage vehicle equipment, roof lifting equipment plays a crucial role, providing necessary shelter and spatial expansion for stage performances. With the continuous development of the scale and form of various events, the performance requirements for roof lifting equipment are also increasing.

[0003] A search revealed Chinese patent CN210707081U, which discloses a stage semi-trailer belonging to the field of stage semi-trailer technology. Specifically, it is a stage semi-trailer comprising a stage panel, side panels hinged to both sides of the stage panel, a roof, and wing panels hinged to both sides of the roof. A hydraulic cylinder is installed between the stage panel and the side panels. The stage semi-trailer in this patent uses a combination of multi-stage hydraulic cylinders and a dedicated guide column mechanism for lifting, thereby increasing the stage height. Outriggers support the entire vehicle, ensuring its load-bearing capacity, wind resistance, and stability.

[0004] Based on the above research and existing technology, it was found that existing ceiling lifting equipment generally suffers from numerous problems. Firstly, poor lifting stability is a prominent issue. Most equipment relies on a simple, single lifting mechanism, which fails to effectively distribute weight during lifting, causing the ceiling to sway during ascent or descent, making precise height control difficult and severely impacting the user experience. Furthermore, a single lifting mechanism cannot withstand significant weight, limiting the size and material selection of the ceiling. Secondly, during operation, the lack of effective protection and cushioning structures between components leads to collisions and friction between adjacent parts during extension and retraction adjustments. This not only generates significant noise but also accelerates component wear, reducing the equipment's lifespan and operational reliability. These shortcomings of unstable lifting and poor operational reliability prevent existing equipment from meeting the lifting needs of complex and varied event spaces and large ceilings, significantly reducing its practicality and work efficiency. This contrasts sharply with the aforementioned cross-frame ceiling lifting equipment with a lifting height of 6-9 meters, which offers stable lifting, heavy load-bearing capacity, stable and quiet operation, and adaptability to complex environments. Utility Model Content

[0005] To address the aforementioned technical issues, this invention proposes a cross-frame roof lifting device with a lifting height of 6-9 meters. The hydraulic cylinder of the second lifting mechanism engages with the connecting ring via a docking plug, assisting in the lifting and alleviating the support force on both sides of the connecting plate. This unique structural design makes the lifting process more stable and reliable, capable of withstanding greater weight, and suitable for stage truck roof lifting operations in various complex environments, greatly improving the equipment's practicality and work efficiency.

[0006] The technical solution to achieve the purpose of this utility model is: a cross-frame type roof lifting equipment with a lifting height of 6-9 meters, including a carriage base, and a stage vehicle roof body on the top of the carriage base that can be adapted to different sizes. Both sides of the stage vehicle roof body are movably connected to outwardly folding side panels, and also includes:

[0007] Cross-frame frame mechanism, with cross-frame frame mechanisms symmetrically arranged on both sides of the top of the carriage base;

[0008] The first lifting mechanism is located on both sides of the corresponding cross frame mechanism. The cross frame mechanism is lifted and lowered by the two sets of first lifting mechanisms. The top of both the cross frame mechanism and the first lifting mechanism is connected to a connecting plate, which is fixedly connected to the bottom of the stage vehicle roof body.

[0009] The second lifting mechanism is located between the two sets of cross-frame mechanisms. Each side of the connecting plate is connected to a connecting ring. The top of the second lifting mechanism is engaged with the connecting ring to drive its lifting and lowering.

[0010] In some embodiments, the cross-frame mechanism includes multiple sets of frame bodies with cross-sections in the shape of a U-shape and movably connected between multiple layers. The front and rear sides of the frame body are reinforced with X-shaped plates. Each set of frame bodies has a fixing strip connected to both ends of the outer top. The first lifting mechanism mainly consists of multiple sets of vertically arranged long strip components and hydraulically driven guide columns disposed inside the long strip components. A detachable silent guide rail mechanism is provided between the outer top of each set of frame bodies and the outer wall of the adjacent long strip component.

[0011] The detachable silent guide rail mechanism includes two L-shaped limiting guide rail plates located inside the top opening of the elongated component, and a docking plate located on the outer side of the top of the elongated component. Bolts three are threadedly connected to the bottom and side adjacent sides of the limiting guide rail plates and the docking plate. The limiting guide rail plates and the docking plates are clamped at the top of the elongated component by the bolts three. The fixing strip on the outer side of the frame body is fixed to a set of adjacent docking plates on the elongated component.

[0012] In some embodiments, the second lifting mechanism includes a hydraulic cylinder with a U-shaped docking plug connected to the top of the hydraulic cylinder, and the hydraulic cylinder drives the docking plug to be inserted into the connecting ring.

[0013] In some embodiments, the bottom of the hydraulic cylinder is connected to an L-shaped base plate. The bottom of the base plate has a slot that matches the bottom crossbar of the bottom frame body at the lowest end. The top of the base plate is provided with multiple sets of bolts, which are used to thread the base plate onto the corresponding top surface of the carriage base.

[0014] In some embodiments, two door panels are provided on both sides of the top of the carriage base, and the door panels are close to the corresponding two first lifting mechanisms.

[0015] In some embodiments, both door panels are L-shaped structures, and a row of reinforcing components is provided between each door panel and the bottom of the housing of the corresponding two first lifting mechanisms. The reinforcing components include horizontally arranged I-shaped connectors, and multiple sets of bolts are threadedly connected to the connectors to thread-fix the door panel and the bottom of the housing of the first lifting mechanism.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this utility model employs a cross-frame structure that works in conjunction with the first and second lifting mechanisms. The cross-frame structure consists of a multi-layered, movable frame body with X-shaped reinforcing plates. The first lifting mechanism uses hydraulically driven guide columns to unfold the elongated components layer by layer, lifting the stage truck roof. The hydraulic cylinder of the second lifting mechanism, through a docking plug and connecting ring, assists in lifting and alleviates the support force on both sides of the connecting plate. This unique structural design makes the lifting process more stable and reliable, capable of withstanding greater weight, and suitable for lifting stage truck roofs in various complex environments, greatly improving the equipment's practicality and work efficiency. Furthermore, the detachable silent guide rail mechanism between the top outer side of each frame body and the outer wall of the adjacent elongated component significantly enhances the stability and safety of the equipment. During the extension and retraction adjustment of the elongated component, adjacent components slide along the L-shaped limiting guide rail, avoiding collisions and friction. This not only provides safety protection but also reduces operating noise and component wear, further extending the equipment's service life and improving its reliability in various scenarios.

[0018] Secondly, this utility model incorporates reinforcing components between the carriage base, door panel, and first lifting mechanism. The door panel has an L-shaped structure and is threadedly fixed to the bottom of the first lifting mechanism's outer shell via an I-beam connector and bolt one. Simultaneously, the L-shaped base plate at the bottom of the second lifting mechanism is connected to the bottom of the cross-frame mechanism via a slot and fixed to the carriage base with bolt two. These connection designs enhance the overall structural tightness and stability. As interconnected bottom support structures, they provide a stable support foundation for the liftable stage carriage canopy, effectively reducing shaking and deformation during operation and extending the equipment's service life. Furthermore, the silent guide rail mechanism, as part of the overall structure, works in conjunction with other connecting structures to further enhance the overall structural stability. It ensures that the long, narrow components experience more even stress during movement, reducing localized stress concentration caused by friction and collisions between components, thereby enhancing the stability and reliability of the entire lifting equipment structure and ensuring long-term stable operation of the equipment.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved cross-frame type ceiling lifting device with a lifting height of 6-9 meters. The technical solution of this utility model is as follows:

[0027] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0028] like Figure 1 - Figure 4 As shown, a cross-frame type roof lifting device with a lifting height of 6-9 meters includes a vehicle body base 1. Two door panels 2 are provided on both sides of the top of the vehicle body base 1, and the door panels 2 are close to two corresponding first lifting mechanisms. Both door panels 2 are L-shaped. A row of reinforcing components is provided between each door panel 2 and the bottom of the outer shell of the corresponding two first lifting mechanisms. The reinforcing components include horizontally arranged I-shaped connectors 201. Multiple sets of bolts 202 are threaded onto the connectors 201 to thread-fix the door panel 2 and the bottom of the outer shell of the first lifting mechanism. The top of the vehicle body base 1 has a stage vehicle roof body 3 with an area that can be adapted to different sizes. Both sides of the stage vehicle roof body 3 are movably connected to outwardly folding side panels 301. The top two sides of the vehicle body base 1 are symmetrically provided with cross-frame mechanisms; the first lifting mechanism is located on both sides of the corresponding cross-frame mechanism, and the cross-frame mechanism is lifted and lowered by two sets of first lifting mechanisms. The top of the cross-frame mechanism and the first lifting mechanism are connected to the connecting plate 401, and the connecting plate 401 is fixedly connected to the bottom of the stage vehicle roof body 3; the second lifting mechanism is located between the two sets of cross-frame mechanisms, and the two sets of connecting plates 401 are connected to the adjacent side of the connecting ring 403. The top of the second lifting mechanism is engaged with the connecting ring 403 to drive its lifting and lowering.

[0029] like Figures 1-4As shown, in one embodiment, the cross-frame mechanism includes multiple sets of frame bodies 5, each consisting of a U-shaped cross-section frame connected movably between multiple layers. The front and rear sides of each frame body 5 have X-shaped reinforcing plates 501. Each set of frame bodies 5 has fixing strips 502 connected to both ends of its outer top surface. The first lifting mechanism mainly consists of multiple sets of vertically arranged elongated components 4 and hydraulically driven guide columns 402 disposed inside the elongated components 4. Each set of frame bodies 5 has a fixing strip 502 horizontally connected to the outer top surface of its adjacent elongated component 4. Each set of frame bodies 5 also has a fixing strip 502 horizontally connected to the outer top surface of its adjacent elongated component 4. A detachable silent guide rail mechanism is provided between the outer walls of adjacent elongated components 4; the detachable silent guide rail mechanism includes two L-shaped limiting guide rail plates 7 located inside the top opening of the elongated component 4, and a docking plate 701 located on the outer side of the top of the elongated component 4. Bolts 702 are threadedly connected to the bottom and side adjacent sides of the limiting guide rail plates 7 and the docking plate 701, and the limiting guide rail plates 7 and the docking plate 701 are clamped at the top of the elongated component 4 by the bolts 702. The fixing strip 502 on the outer side of the skeleton frame body 5 is fixed to a set of adjacent docking plates 701 on the elongated component 4. By providing a detachable silent guide rail mechanism between the top outer side of each set of skeleton frame body 5 and the outer wall of the adjacent long strip component 4, when the two corresponding adjacent long strip components 4 are extended and retracted, the adjacent components will not collide or rub against each other, but will slide along the L-shaped limiting guide plate 7, which provides a safety protection effect for the adjacent long strip components 4 that are extending and retracting. At the same time, the elastic limiting guide plate 7 provides a silent effect for the long strip components 4 that are sliding up and down. Furthermore, by adjusting the distance between the limiting guide plate 7 and the docking plate 701, specifically by controlling the horizontal end bolt three 702 to adjust the distance between the docking plate 701 located on the inner side of the corresponding long strip component 4, the gap between the two long strip components 4 can be controlled.

[0030] By setting up multiple sets of skeleton frame bodies 5, reinforcing plates 501, fixing strips 502, long strip components 4, and hydraulic drive guide columns 402, when the hydraulic drive guide columns 402 inside the long strip components 4 rise, the multiple sets of long strip components 4 will extend upward with the hydraulic drive guide columns 402, causing the multiple sets of long strip components 4 to gradually unfold upward in layers. At the same time, the outer side of each set of long strip components 4 will simultaneously unfold and rise upward in multiple sets through the fixing strips 502, realizing the function of lifting the stage vehicle roof body 3. Furthermore, the multi-layer movable skeleton frame bodies 5 and the X-shaped reinforcing plates 501 enhance the stability and strength of the structure.

[0031] like Figure 2As shown, in one embodiment, the second lifting mechanism includes a hydraulic cylinder 6, with a U-shaped docking plug 601 connected to the top of the hydraulic cylinder 6. The hydraulic cylinder 6 drives the docking plug 601 to insert into the connecting ring 403. Through the arrangement of the hydraulic cylinder 6, the docking plug 601 and the connecting ring 403, the support force on both sides of the connecting plate 401 is further relieved. In conjunction with the first lifting mechanism, the stage vehicle canopy body 3 on the connecting plate 401 can be stably raised and lowered, reducing the pressure on each cross frame mechanism.

[0032] like Figure 2 , Figure 3 As shown, in one embodiment, the bottom of the hydraulic cylinder 6 is connected to an L-shaped base plate 602. The bottom of the base plate 602 has a slot 604 that matches the bottom crossbar of the bottom of the lowest middle frame body 5. The top of the base plate 602 is provided with multiple sets of bolts 603, which are used to thread the base plate 602 onto the corresponding top surface of the carriage base 1. By providing a base plate 602 at the bottom of the second lifting mechanism, the second lifting mechanism is not only fixedly installed on the top of the carriage base 1, but also the lowest end of the second lifting mechanism is connected to the bottom of the cross frame mechanism to form a whole, thereby improving the stability of the overall structure.

[0033] like Figure 4 As shown, in one embodiment, two door panels 2 are provided on both sides of the top of the carriage base 1, and the door panels 2 are close to the corresponding two first lifting mechanisms. The door panels 2 facilitate the entry and exit of personnel into the interior space of the carriage base 1, and the positions of the door panels 2 and the first lifting mechanisms are reasonably set so as not to affect the normal operation of the first lifting mechanisms.

[0034] like Figure 4 As shown, in one embodiment, both door panels 2 are L-shaped structures, and a row of reinforcing components is provided between each door panel 2 and the bottom of the outer shell of the corresponding two first lifting mechanisms. The reinforcing components include horizontally arranged I-shaped connectors 201, and multiple sets of bolts 202 are threadedly connected to the connectors 201 to thread-fix the door panel 2 and the bottom of the outer shell of the first lifting mechanism. Through the arrangement of door panels 2, connectors 201 and bolts 202, the first lifting components and the door panels 2 corresponding to the top of the carriage base 1 are further fixedly connected to form another whole, realizing the function of improving the connection tightness and overall mechanism stability. As a support at the bottom position, multiple sets of structures are interconnected, which plays a stable supporting role on the bottom of the liftable stage carriage roof body 3.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to lift the stage truck canopy body 3, the hydraulic drive guide column 402 in the first lifting mechanism first extends upward, driving multiple sets of long strip components 4 to gradually unfold upward in layers. At the same time, the frame body 5 in the cross frame mechanism is simultaneously unfolded and raised upward through the fixing bar 502. Simultaneously, the hydraulic cylinder 6 in the second lifting mechanism drives the docking plug 601 to insert into the connecting ring 403, lifting it upward, further assisting the rise of the stage truck canopy body 3, relieving the supporting force on both sides of the connecting plate 401, and allowing the stage truck canopy body 3 to rise stably to the required height. During descent, the hydraulic drive guide column 402 and the hydraulic cylinder 6 move in opposite directions, causing the stage truck canopy body 3 to descend to the initial position. Throughout the process, the door panel 2 and the first lifting mechanism maintain a stable connection through reinforcing components, providing stable bottom support for the stage truck canopy body 3. Furthermore, the reinforcing plate 501 on the frame body 5 ensures the structural strength and stability of the cross frame mechanism; at the same time, when the long strip component 4 of the first lifting mechanism is extended or retracted, the detachable silent guide rail mechanism can effectively prevent adjacent long strip components 4 from colliding and rubbing, achieving safety protection and silent effect, further ensuring the stability and reliability of the entire equipment operation.

Matters not covered in this utility model are common knowledge to those skilled in the art.
