Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and specifically to lifting platforms. Background Technology

[0002] As a key piece of equipment for vertical transportation of goods or personnel, lifting platforms are now classified into two categories based on mobility: fixed and mobile. From a power perspective, they can be hydraulically, electrically, or pneumatically driven. Among them, hydraulic lifting platforms have strong stability and high load capacity, electric lifting platforms have high speed and high lifting height, and pneumatic lifting platforms have a simple structure and low energy consumption. They are widely used in industrial manufacturing, logistics warehousing, construction and other fields.

[0003] Traditional lifting platforms mostly employ a fixed-height design, requiring manual handling or adjustment with the aid of other auxiliary equipment. This process is cumbersome and inefficient, failing to meet the needs of operations at varying heights. Some liftable platforms have complex lifting structures and poor operational stability, prone to swaying and jamming during lifting, which not only affects work efficiency but also poses significant safety hazards. Furthermore, traditional designs often lack adequate safety measures, failing to provide reliable safety guarantees for workers. Therefore, there is an urgent need to design lifting platforms to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a lifting platform to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting platform includes a fixed ladder and a base. The fixed ladder is welded to the upper surface of the base. A sliding ladder is slidably connected to the outside of the fixed ladder. Slide grooves are formed in the support rods on both sides of the fixed ladder. Sliding rods are provided on both sides of the sliding ladder, and sliding rollers are provided on the sliding rods. The sliding rollers slide in the slide grooves. A transmission mechanism is provided on both sides of the fixed ladder. The transmission mechanism includes several guide wheels set on the slide grooves. Steel wire ropes are set in the grooves of the guide wheels. A lifting mechanism is provided on the upper surface of the base. The lifting mechanism is located below the sliding ladder, and one end of the steel wire rope is fixed to the lifting mechanism.

[0007] In a preferred embodiment of this utility model, a fixing bolt is provided on the outer wall of the sliding rod, and one end of the steel wire rope is fixed to the fixing bolt.

[0008] In a preferred embodiment of this utility model, the lifting mechanism includes two winding rollers disposed on the top surface of the base, a transmission rod disposed between the two winding rollers, a gear 1 disposed on the transmission rod, a worm gear disposed below the gear 1, and the worm gear meshing with the gear 1.

[0009] A motor is installed on the top surface of the base. A gear is installed on one end of the output shaft of the motor and one end of the worm gear. The gear on the output shaft of the motor meshes with the gear on the worm gear. The winding roller is used to wind up and unwind the wire rope.

[0010] In a preferred embodiment of this utility model, the base includes an outer support base, a movable base is inserted into the outer support base, a plurality of sliding wheels are provided on both sides of the movable base, a slide rail is provided on the outer support base, the sliding wheels slide in the slide rail, and a ladder is provided at one end of the movable base.

[0011] In a preferred embodiment of this utility model, a working platform is welded to the top of the sliding ladder, the upper surface of the working platform is provided with anti-slip ridges, and a guardrail is provided around the upper surface of the working platform.

[0012] In a preferred embodiment of this utility model, both the fixed ladder and the sliding ladder are welded with handrails, which are respectively welded to the slide groove and the sliding rod.

[0013] In a preferred embodiment of this utility model, a control switch is provided on the guardrail, and the control switch is used at least to control the lifting and lowering of the work platform.

[0014] In the above technical solution, the lifting platform provided by this utility model has the following beneficial effects:

[0015] (1) By setting up a lifting mechanism, the lifting platform uses a sliding ladder set outside the fixed ladder, and the sliding rollers on the sliding rod slide in the sliding groove. With the help of the wire rope and guide wheel in the transmission mechanism, as well as the lifting mechanism, the platform can be lifted smoothly, making the lifting process smoother and more stable. It can effectively avoid shaking and jamming, and greatly improve the work efficiency.

[0016] (2) By setting up a work platform with anti-slip ridges and guardrails, it is possible to prevent workers from slipping or falling on the platform. The control switch on the guardrail allows workers to directly control the lifting and lowering on the platform, avoiding the inconvenience and safety risks caused by remote operation.

[0017] (3) By setting up fixed ladders and sliding ladders, stairs are installed on the fixed ladders and sliding ladders to facilitate operators to quickly enter the work platform. At the same time, the handrails on the fixed ladders and sliding ladders provide reliable gripping points for people to climb, making the work convenient and safe. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, the lifting platform provided in this embodiment of the utility model includes a fixed ladder 1 and a base 2. The fixed ladder 1 is welded to the upper surface of the base 2. A sliding ladder 5 is slidably connected to the outside of the fixed ladder 1. Slide grooves 11 are provided in the support rods on both sides of the fixed ladder 1. Sliding rods 51 are provided on both sides of the sliding ladder 5. Sliding rollers 52 are provided on the sliding rods 51. The sliding rollers 52 slide in the slide grooves 11. Transmission mechanisms 7 are provided on both sides of the fixed ladder 1. The transmission mechanism 7 includes a plurality of guide wheels 72 provided on the slide grooves 11. Steel wire ropes 71 are provided in the grooves of the guide wheels 72. A lifting mechanism 4 is provided on the upper surface of the base 2. The lifting mechanism 4 is located below the sliding ladder 5. One end of the steel wire rope 71 is fixed to the lifting mechanism 4.

[0026] In this embodiment, a sliding ladder 5 is slidably connected to the outside of the fixed ladder 1. The fixed ladder 1 is welded from high-strength aluminum alloy, and the sliding ladder 5 is also made of aluminum alloy. The support rods on both sides of the fixed ladder 1 are provided with sliding grooves 11. The sliding grooves 11 are processed by high-precision milling to ensure smooth operation of the sliding parts. Sliding rods 51 are provided on both sides of the sliding ladder 5. Sliding rollers 52 are provided on the sliding rods 51. The sliding rollers 52 are made of high-strength nylon 66 material and have embedded deep groove ball bearings. The sliding rollers 52 slide in the sliding grooves 11. Two sliding rollers 52 are provided on each sliding rod 51, which can effectively distribute pressure and prevent shaking during the lifting and lowering process.

[0027] Specifically, a fixing bolt 53 is provided on the outer wall of the sliding rod 51. The fixing bolt 53 is an 8.8 grade high-strength bolt, with a spring washer and a lock nut. One end of the wire rope 71 is fixed to the fixing bolt 53. The wire rope 71 is connected to the fixing bolt 53 through a U-shaped clamp to ensure the reliability of the connection.

[0028] In this embodiment, a lifting mechanism 4 is provided on the upper surface of the base 2. The lifting mechanism 4 is located below the sliding ladder 5. One end of the wire rope 71 is fixed to the lifting mechanism 4. The lifting mechanism 4 includes two winding rollers 42 provided on the top surface of the base 2. The surfaces of the two winding rollers 42 are machined with spiral guide grooves. The groove spacing is precisely matched with the diameter of the wire rope 71, which can guide the wire rope 71 to wind in an orderly manner and avoid the phenomenon of tangled rope. A transmission rod 44 is provided between the two winding rollers 42. The transmission rod 44 is connected to the gear 45 by a spline connection. The gear 45 is provided on the transmission rod 44. A worm gear 43 is provided below the gear 45. The worm gear 43 is made of 40Cr alloy steel and meets the self-locking condition to prevent the work platform 3 from sliding down unexpectedly. The worm gear 43 meshes with the gear 45. Both the gear 45 and the gear 46 are made of 20CrMnTi carburized steel.

[0029] Specifically, a motor 41 is installed on the top surface of the base 2. The motor 41 is a 1.5kW three-phase asynchronous motor equipped with an electromagnetic brake, which can achieve emergency braking at the moment of power failure. Gear 46 is installed on one end of the output shaft of the motor 41 and the worm 43. Gear 46 on the output shaft of the motor 41 meshes with gear 46 on the worm 43. The winding roller 42 is used to wind up and unwind the wire rope 71.

[0030] In this embodiment, the base 2 adopts a double-layer nested design. The base 2 includes an outer support 21, which is a box-shaped welded structure with internal reinforcing ribs. A movable seat 22 is inserted into the outer support 21. Several sliding wheels 24 are provided on both sides of the movable seat 22. Eight sliding wheels 24 are symmetrically distributed on both sides of the movable seat 22. The sliding wheels 24 are polyurethane-coated cast iron wheels, which run smoothly and have low noise. A slide rail 25 is provided on the outer support 21. The slide rail 25 has an I-shaped cross section. The sliding wheels 24 slide within the slide rail 25. A ladder 23 is provided at one end of the movable seat 22 to facilitate the operator's ascent and descent.

[0031] In this embodiment, the fixed ladder 1 is welded to the upper surface of the base 2. Both sides of the fixed ladder 1 are provided with transmission mechanisms 7. The transmission mechanism 7 includes several guide wheels 72 set on the slide groove. The guide wheels 72 adopt aluminum alloy wheel hub with nylon wheel groove. The radius matches the steel wire rope 71, which can effectively reduce the wear of the steel wire rope 71. The steel wire rope 71 is set in the groove 11 of the guide wheel 72. The steel wire rope 71 is selected as galvanized steel wire rope 71 with 6×19+IWS structure.

[0032] In this embodiment, a work platform 3 is welded to the top of the sliding ladder 5. The work platform 3 is made of patterned steel plate and has anti-slip ridges 31 on its upper surface. The anti-slip ridges 31 are 2mm high and 20mm apart. A guardrail 32 is provided around the upper surface of the work platform 3. The guardrail 32 is 1.2m high and is made of steel pipe with a diameter of 32mm. The horizontal bars are spaced 400mm apart and a vertical post is set in the middle. The overall impact resistance is strong.

[0033] In this embodiment, both the fixed ladder 1 and the sliding ladder 5 are welded with handrails 6. The handrails 6 are welded to the slide groove 11 and the sliding rod 51 respectively. The handrails 6 are 900mm high and are made of the same material as the guardrail 32. Reinforcing crossbars are set every 300mm to ensure the safety of workers during the climbing process.

[0034] In this embodiment, a control switch 8 is provided on the guardrail 32. The control switch 8 adopts a waterproof and dustproof button design. The control switch 8 is used to control the lifting of the work platform 3. The lifting platform can be controlled not only by the control switch 8, but also by a wireless remote control. Wireless remote control is a common existing technology, so this application document will not elaborate on it further.

[0035] Working steps: 1. Move the lifting platform to the work site, then pull out the movable seat 22 to enhance the stability of the bottom of the lifting platform, and then start the motor 41. The gear 46 on the output shaft of the motor 41 drives the gear 46 on the worm gear 43 to rotate, which in turn makes the worm gear 43 rotate. The worm gear 43 drives the transmission rod 44 and the winding roller 42 to rotate, thereby winding up the wire rope 71. The wire rope 71 is guided by the guide wheel 72 and pulls the fixing bolts 53 on the sliding rods 51 on both sides of the sliding ladder 5, so that the sliding ladder 5 slides upward along the slide groove 11 of the fixed ladder 1, driving the work platform 3 to rise.

[0036] 2. Workers climb onto the work platform 3 with the help of the handrails 6 on the fixed ladder 1 and the sliding ladder 5, stand on the platform with anti-slip texture 31, and hold onto the guardrail 32 to carry out the work.

[0037] 3. After the operation is completed, press the control switch 8 again to start the motor 41, so that the take-up roller 42 releases the wire rope 71, and the working platform 3 slowly descends to the initial position.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
