Description

Technical Field

[0001] This utility model belongs to the field of lifting platform technology, and in particular relates to a guide rail type hydraulic lifting operation platform. Background Technology

[0002] In modern industry and construction, with the increasing prevalence of high-rise buildings and complex industrial facilities, there is a growing demand for efficient and safe vertical transportation solutions for goods and personnel. While traditional elevators are widely used inside buildings, their applicability and flexibility are limited for certain special scenarios, such as factory workshops, warehouses, and temporary construction sites. Furthermore, existing hydraulic lifting platforms, although solving the problem of vertical transportation to some extent, still have many shortcomings. For example, some lifting platforms have poor lateral stability and are prone to swaying during operation, posing safety hazards for transporting delicate goods or for personnel working at heights; others have limited thrust in their drive systems, unable to meet high-load requirements; and still others cannot effectively prevent objects from accidentally falling from upper levels when not in use, posing a safety risk. Therefore, developing a new type of guide rail-type hydraulic lifting platform, aiming to provide a compact, stable, safe, reliable, and easy-to-install and maintain lifting device, has become an urgent problem to be solved in the industry.

Specific Implementation Example 1:

[0030] Please see Figure 1-8 As shown, this utility model is a guide rail type hydraulic lifting platform, including a guide frame 1, a lifting platform 2, and a tilting platform 3. The guide frame 1 is vertically installed on the side of a wall. The lifting platform 2 is vertically mounted on the guide frame 1, allowing it to move up and down. A hydraulic drive assembly for driving the lifting platform 2 to move up and down is installed between the guide frame 1 and the lifting platform 2. The tilting platform 3 is rotatably mounted on the guide frame 1 via two pins 4. A support plate 5 is provided on the lifting platform 2 to push the tilting platform 3 upwards from below. The guide frame 1 is vertically mounted on the wall using expansion bolts and is used for lifting and transferring goods between adjacent floors. The floor slab between the floors has a passage for the lifting platform 2 to pass through, and a guardrail with a door is installed around the passage. The area of ​​the tilting platform 3 is larger than the area of ​​the passage. The hydraulic drive assembly drives the lifting platform 2 to move smoothly up and down along the guide frame 1. When the lifting platform 2 moves to the lower position, the support plate 5 disengages from supporting the tilting platform 3, and the tilting platform 3 blocks the passage on the floor slab, preventing objects from falling from the upper floor and affecting the lower floor when the lifting platform is not in use. When the hydraulic drive assembly drives the lifting platform 2 to rise along the guide frame 1, the support plate 5 will push the tilting platform 3 open and flip it upward to open the passage on the floor slab.

[0031] The specific guide frame 1 includes two vertically parallel guide rails 11; the cross-section of the guide rail 11 is E-shaped; a row of strips 12 is fixed to the rear wall of the two guide rails 11; two pairs of first circular through holes 13 are opened on the strips 12; a rectangular base plate 14 is fixed between the opposite sides of the bottom of the two guide rails 11; a single lug that is inserted and engaged with the pin 4 is fixed to the front wall of the guide rail 11. The lifting platform 2 includes a "["-shaped guide trough plate 21, which has a side opening and is "["-shaped. Two anti-deviation rollers 22 that cooperate with the middle vertical plates of the guide rails 11 are fixed to the opposite inner walls of the guide trough plate 21. Two sets of short shafts 23 are fixed to the adjacent inner walls of the guide trough plate 21. At least one bearing 24 that cooperates with the inner wall opposite to the two guide rails 11 is installed on the short shafts 23. A row of vertically arranged connecting vertical plates 25 is fixed to the outer wall of the guide trough plate 21 away from its opening direction. A support plate 5 is fixed to the top surface of the row of connecting vertical plates 25. A platform frame 26 is fixed to the free end of the row of connecting vertical plates 25. A lifting platform carrier plate 27 is fixed on the platform frame 26. The hydraulic drive assembly specifically includes a hydraulic cylinder 6, a slide 7, and two chains 8. The slide 7 has vertically arranged guide bars 15 fixed to its inner walls opposite each other on the guide rail 11. Guide slots that mate with the guide bars 15 are respectively opened at both ends of the slide 7. Two sprockets 71 with shafts are mounted on the upper surface of the slide 7 via two bearing seats. The two chains 8 are wound around the two sprockets 71. One end of each chain 8 is fixed to a rectangular base plate 14, and the other end is fixed to a guide groove plate 21. The bottom of the hydraulic cylinder 6 is mounted on the rectangular base plate 14. The telescopic end of the hydraulic cylinder 6 is connected to the bottom surface of the slide 7. The hydraulic cylinder 6 is connected to a hydraulic drive unit, which includes a hydraulic pump station, oil pipes, and control valves. The hydraulic cylinder 6 is pushed to extend and retract by the hydraulic oil pressure, achieving smooth lifting and lowering of the lifting platform 2.

[0032] The guide rail type hydraulic lifting platform of this embodiment is composed of a guide frame 1, a lifting platform 2, a tilting platform 3, a hydraulic drive assembly and a support plate 5. The overall structure is compact and occupies a small area, making it suitable for transferring goods between floors.

[0033] The tilting platform 3 includes a tilting platform frame 31; two double lugs 32 are fixed to the rear wall of the tilting platform frame 31, which are inserted into the pins 4; a tilting platform carrier plate 33 is fixed to the upper surface of the tilting platform frame 31, and the area of ​​the tilting platform is larger than the area of ​​the lifting platform carrier plate 27; the tilting platform frame 31 and the tilting platform carrier plate 33 have two rectangular through slots 34, which are respectively connected to two chains 8; three parallel rectangular connecting plates 35 are fixed to the lower surface of the tilting platform frame 31, and the rectangular connecting plates 35 are perpendicular to the rectangular through slots 34. The size of the tilting platform frame 31 is slightly smaller than the size of the passage on the floor slab, and the size of the tilting platform carrier plate 33 is larger than the size of the passage on the floor slab. When the tilting platform 3 is tilted downward to a horizontal state, the tilting platform carrier plate 33 covers the passage on the floor slab, effectively preventing objects from falling from the passage on the floor slab when the lifting platform is not in use. The upper end of the support plate 5 is provided with an arc plate part 51, and the outer arc surface of the arc plate part 51 abuts against the tilting platform 3, ensuring the smoothness of the tilting process when the support plate 5 pushes the tilting platform 3 to tilt.

[0034] In order to ensure that the tilting platform plate 33 can be flipped back in time when the lifting platform 2 descends, the front wall of the guide rail 11 is fixed with a spring that abuts against the tilting platform plate 33.
