Description

Technical Field

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

[0002] In the field of stage trucks and related technologies, roof lifting equipment plays a crucial role in expanding stage space and meeting diverse performance needs. With the increasing diversification of performance formats, higher demands are being placed on roof lifting equipment in terms of height adjustment flexibility, stability, and safety.

[0003] A search revealed Chinese patent CN220764200U, which discloses a stage vehicle roof and side wing lifting linkage mechanism, which uses a relatively simple structure for roof lifting operation.

[0004] Based on the above research and existing technology, it was found that existing roof lifting equipment has many shortcomings in its structural design. Among them, the problem with height adjustment is the most prominent. Most existing equipment adopts a simple direct lifting method, lacking a stepped stacking design such as a parallel frame plate mechanism. This makes the roof height adjustment inflexible, making it difficult to accurately adjust in stages within a height range of 6-9 meters, and unable to meet the needs of diverse performance scenarios. At the same time, this simple structure has poor stability, making it difficult to achieve a large lifting height in limited spaces, with limited load-bearing capacity, and it cannot be flexibly adjusted according to needs during transportation and storage.

[0005] Besides the height adjustment issue, existing lifting equipment lacks a robust dual safety protection structure, making the frame prone to retraction after lifting and compromising safety. Regarding lateral space expansion, existing stage trucks suffer from inconvenient lateral space expansion, with unreasonable designs for the side panels and support rods, failing to meet the lateral support requirements of complex venues. During operation, problems such as high noise levels, uneven lifting, and inconvenient operation also exist, along with difficult maintenance and limited functional expansion, all of which severely impact the equipment's efficiency and lifespan. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a parallel frame type roof lifting equipment with a lifting height of 6-9 meters. The equipment utilizes a guide baffle made of elastic rubber in the limiting sliding guide rail, which acts as a buffer during the sliding of the connecting sleeve, reducing collision noise, extending the service life of components, and solving the problem of excessive noise and easy wear caused by component collisions in some existing lifting equipment during operation.

[0007] The technical solution to achieve the purpose of this utility model is: a parallel frame roof lifting equipment with a lifting height of 6-9 meters, including a vehicle body base, and also including;

[0008] The stage truck roof body is located on the rear side of the top of the truck body base, and both sides of the truck body base are provided with side truck bodies that can be flipped outward and adjusted.

[0009] The parallel frame plate mechanism is symmetrically arranged on the rear side of the top of the carriage base. It is used to adjust the height distance between the stage vehicle canopy body and the carriage base. The parallel frame plate mechanism includes multiple sets of vertically adjustable sub-frames, and the multiple sets of sub-frames are stacked vertically in a stepped manner. The uppermost terminal frame is fixedly connected to the bottom of the stage vehicle canopy body by a top plate.

[0010] The sub-frame includes a support frame and connecting sleeves symmetrically arranged on both sides of the support frame. The upper connecting sleeve is inserted into the interior of the lower connecting sleeve between the upper and lower sub-frames.

[0011] The limiting sliding guide rail has a ring on the top inner and outer sides of each set of connectors. Each of the four outer ends of the bottom of the upper connector slides on the inner end of the corresponding limiting sliding guide rail. Each set of limiting sliding guide rails is symmetrically arranged in an inverted L-shaped structure. A connecting block is fixedly connected between the connector and the two sets of support frames.

[0012] A lifting mechanism is provided, which is located between two parallel frame plate mechanisms, and the top of the lifting mechanism is connected to the bottom of the corresponding top plate.

[0013] In some embodiments, the limiting sliding guide rail includes a guide baffle disposed on the upper end of each side of the inner perimeter of the connecting sleeve and a clamping plate on the outer perimeter of the connecting sleeve. The top and sides of the clamping plate and the guide baffle are all threaded with fixing bolts, and a connecting block is connected between the clamping plate and the support frame.

[0014] In some embodiments, each set of guide baffles is a rubber baffle made of a flexible material.

[0015] In some embodiments, the lifting mechanism includes a hydraulic cylinder and a mounting plate connected to the top output end of the hydraulic cylinder, the mounting plate being fixedly connected to the top plate.

[0016] In some embodiments, each of the parallel skeleton plate mechanisms is equipped with an electrical control box.

[0017] In some embodiments, each of the hydraulic cylinders is fixedly welded to the top of the carriage base.

[0018] Compared with existing technologies, the significant advantages of this invention are:

[0019] Firstly, this utility model, by setting up a parallel frame plate mechanism, includes multiple sets of sub-frames stacked in a stepped manner and adjustable up and down. The sub-frames are connected by interlocking fittings and limit sliding guide rails, which realizes flexible adjustment of the height of the stage canopy. In practical applications, this design can quickly and stably raise or lower the canopy to meet the diverse needs of different performance scenarios and venue spaces, and has extremely high practicality, greatly expanding the application range of the stage truck.

[0020] Secondly, this utility model uses hydraulic cylinders as the power source for the lifting mechanism. Connected to the top plate via a mounting plate, it drives multiple sub-frames to lift and lower. It boasts strong power and convenient control, enabling height adjustment from six to nine meters. This solves the problems of insufficient power and limited height adjustment in some existing lifting equipment, failing to meet the needs of higher spaces. Simultaneously, each hydraulic cylinder has a fixed welded base to the truck bed base, ensuring the stability of the cylinders during operation and thus improving the smoothness and safety of the entire lifting process.

[0021] Thirdly, this utility model uses a guide baffle made of elastic rubber in the limiting sliding guide rail, which plays a buffering role during the sliding of the connecting sleeve, reduces collision noise, extends the service life of the components, and solves the problem that some existing lifting equipment generates a lot of noise due to component collision during operation and is prone to component wear. At the same time, when two connecting sleeves of different widths are connected, the gap at the connection of the connecting sleeves of different widths can be adjusted by adjusting the fixing bolts at the horizontal position between the guide baffle and the clamping plate.

[0022] Fourthly, this utility model installs an electrical control box on the parallel frame plate mechanism, realizing intelligent control of the lifting equipment, which facilitates precise operation by operators, improves work efficiency, and also facilitates monitoring of equipment operating status and troubleshooting. It solves the problems of complex operation and difficulty in real-time monitoring of equipment status in some existing lifting equipment. Attached Figure Description

[0030] 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.

[0031] This utility model provides an improved parallel frame type ceiling lifting device with a lifting height of 6-9 meters. The technical solution of this utility model is as follows:

[0032] like Figure 1 - Figure 4 As shown, a parallel frame type roof lifting device with a lifting height of 6-9 meters includes a carriage base 1, a stage truck roof body 4 located on the top rear side of the carriage base 1, and side carriage panels 5 that can be tilted outwards and adjusted on both sides of the carriage base 1; a parallel frame plate mechanism is symmetrically arranged on the top rear side of the carriage base 1 to adjust the height distance between the stage truck roof body 4 and the carriage base 1. The parallel frame plate mechanism includes multiple sets of vertically adjustable sub-frames, and the multiple sets of sub-frames are stacked vertically in a stepped manner. The uppermost terminal frame is fixedly connected to the bottom of the stage truck roof body 4 by a top plate 303. The sub-frame includes a support frame 301 and connecting sleeves 3 symmetrically arranged on both sides of the support frame 301. The upper connecting sleeve 3 is inserted into the lower connecting sleeve 3 between the upper and lower sub-frames. A limiting sliding guide is provided on the inner and outer sides of the top of each connecting sleeve 3. Each of the four outer ends of the bottom of the upper connecting sleeve 3 slides on the inner end of the corresponding limiting sliding guide. Each limiting sliding guide is a symmetrically arranged inverted L-shaped structure. A connecting block is fixedly connected between the connecting sleeve 3 and the two sets of support frames 301. The lifting mechanism is arranged between the two parallel frame plate mechanisms, and the top of the lifting mechanism is connected to the bottom of the corresponding top plate 303.

[0033] like Figure 4As shown, in one embodiment, the limiting sliding guide rail includes guide baffles 6 disposed on the upper end of each side of the inner perimeter of the connecting sleeve 3 and clamping plates 601 on the outer perimeter of the connecting sleeve 3. The top and sides of the clamping plates 601 and the guide baffles 6 are all threadedly connected with fixing bolts 602. A connecting block 302 is connected between the clamping plates 601 and the support frame 301. Through the setting of the guide baffles 6, clamping plates 601, fixing bolts 602 and connecting blocks 302, the stable installation and fixing of the limiting sliding guide rail is realized, which can effectively limit and guide the sliding of the connecting sleeve 3, ensuring that the sub-frame slides smoothly along the predetermined trajectory during the lifting process, and improving the stability and reliability of the entire lifting equipment structure.

[0034] In one embodiment, each set of guide baffles 6 is made of elastic rubber. By using elastic rubber baffles as guide baffles 6, the elasticity of the rubber baffles can buffer when the connecting sleeve 3 comes into contact with the guide baffle 6 during the sliding process, reducing hard collisions between the connecting sleeve 3 and the guide baffle 6, reducing noise, extending the service life of the guide baffle 6 and the connecting sleeve 3, and improving the stability of the lifting equipment during operation. Furthermore, when two connecting sleeves 3 of different widths are connected, the limiting guide rail mechanism can adjust the gap at the connection of connecting sleeves 3 of different widths by adjusting the fixing bolts 602 at the horizontal position between the guide baffle 6 and the clamping plate 601.

[0035] like Figure 1 - Figure 2 As shown, in one embodiment, the lifting mechanism includes a hydraulic cylinder 2 and a mounting plate 201 connected to the top output end of the hydraulic cylinder 2. The mounting plate 201 is fixedly connected to the top plate 303 (the lifting mechanism drives the top plate 303 through the hydraulic cylinder 2 to adjust the height of multiple stacked sub-frames by raising them up and down. The height can be raised from six to nine meters, raising the stage truck canopy body 4 upwards). Through the setting of the hydraulic cylinder 2 and the mounting plate 201, the extension and retraction drive of the hydraulic cylinder 2 is used to drive the top plate 303 through the mounting plate 201, thereby driving the multiple sub-frames to rise and fall, realizing the height adjustment of the stage truck canopy body 4, meeting the height requirements of the stage truck canopy body 4 in different usage scenarios. Furthermore, the driving method of the hydraulic cylinder 2 has the advantages of strong power and convenient control, improving the lifting efficiency and operation convenience of the lifting equipment.

[0036] like Figure 1 As shown, in one embodiment, each of the parallel frame plate mechanisms is equipped with an electrical control box 7; the electrical control box 7 enables electrical control of the parallel frame plate mechanism, facilitating operators to precisely control the lifting and lowering actions of the lifting equipment, improving the intelligence level and work efficiency of the operation, and also facilitating the monitoring of the equipment's operating status and troubleshooting, thus ensuring the normal operation of the equipment.

[0037] like Figure 2 As shown, in one embodiment, each of the hydraulic cylinders 2 is fixedly welded to the top of the carriage base 1 with a base 202; the base 202 is used to fix the hydraulic cylinder 2 stably, so that the hydraulic cylinder 2 remains stable during operation and will not shake or shift, thus ensuring the stability and reliability of the hydraulic cylinder 2 drive, and thus ensuring the smoothness and safety of the lifting action of the entire lifting equipment.

[0038] The working principle and usage process of this utility model are as follows: When it is necessary to raise the stage truck roof body 4, the operator starts the hydraulic cylinder 2 of the lifting mechanism through the electrical control box 7. The output end of the hydraulic cylinder 2 extends, driving the top plate 303 upward through the mounting plate 201. The top plate 303 drives the uppermost sub-frame to rise. Since the upper connecting sleeve 3 between the upper and lower sub-frames is inserted into the interior of the lower connecting sleeve 3, and the bottom of the upper connecting sleeve 3 slides between the limiting sliding guide rails, as the uppermost sub-frame rises, the other sub-frames will also be driven to rise in sequence. Through the coordinated rise of multiple sub-frames, the stage truck roof body 4 is raised, and the height can be adjusted to six to nine meters. When it is necessary to lower the stage truck roof body 4, the output end of the hydraulic cylinder 2 retracts, driving the top plate 303 and the sub-frames to descend, ultimately restoring the stage truck roof body 4 to its initial height. During the entire lifting process, the side carriage 5 can be flipped outward as needed to adapt to different usage scenarios.

[0039] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
