Description
Technical Field
[0001] The utility model belongs to the technical field of lift, and particularly relates to a boarding plate of a scissor lift. Background Technique
[0002] A scissor lift is a vehicle repair machine used in the automotive repair industry. It is generally driven by a hydraulic system to lift and lower, so it is also called a hydraulic lift. The scissor lift plays a crucial role in automotive repair and maintenance. For a complete vehicle overhaul and maintenance, a scissor lift is indispensable. There are boarding plates on both sides of the top plate of the lifting platform. The function of the boarding plate is that when the lift descends to the lowest position, the boarding plate and the lifting platform form a ramp, which is convenient for driving the vehicle onto the top plate of the lifting platform.
[0003] For the existing boarding plates, most of them connect the axle pin to the top plate of the boarding plate and the middle bracket at the top. The middle bracket part can rotate along this axle pin. At the connection end with the top plate of the lift, there is a bracket hook, and the middle bracket of the boarding plate can be placed in the groove of the hook on the top plate of the lift, so as to support the top plate of the boarding plate. However, the angle of this structure cannot be controlled and only plays a supporting role. After the top plate of the boarding plate is lowered, the angle formed between the direction of the boarding plate and the horizontal direction of the top plate is mostly 40° or smaller. Its disadvantage is that when the scissor lift is working, the smaller the angle formed between the direction of the boarding plate and the horizontal of the top plate, and at the same time, if the distance between the vehicle tires is small, it is easier to contact the vehicle tires at the beginning of the ascent or descent. The boarding plate of the lift will get stuck in the tires, preventing the lift from lifting, and further causing the boarding plate to damage the tires, affecting the stability of the vehicle during the lifting process, which is also a safety hazard for the staff. Therefore, we have proposed a boarding plate of a scissor lift. Content of the Utility Model
[0004] In order to solve the problem that when the current scissor lift is working, the smaller the angle formed by the direction of the upper car plate and the horizontal of the top plate, and at the same time, if the distance between the automobile tires is small, it is easier to contact the automobile tires at the beginning of rising or falling. The upper car plate of the lift will get stuck in the tires, preventing the lift from lifting, and further causing the upper car plate to damage the tires and affecting the stability of the vehicle during the lifting process. The present utility model provides the following technical solutions: An upper car plate of a scissor lift, including a top plate, both opposite side walls of the top plate are provided with side plates, and on the two side plates, upper car plate assemblies are respectively connected through connecting seats. The upper car plate assembly includes an upper car plate, and the upper car plate is rotatably connected to the upper side of the connecting seat through a first pin. The lower part of the connecting seat is rotatably connected to a connecting device through a second pin. A cross plate is arranged at the bottom of the upper car plate, and two brackets are symmetrically arranged on both sides of the cross plate. A sliding space is formed between the two brackets and the upper car plate. The two ends of the connecting device are provided with bearing plates, and the two bearing plates are respectively slidably connected in the two sliding spaces. A support rod is arranged on the side of the connecting device away from the connecting seat, and the support rod can be detachably supported on the side wall of the cross plate.
[0005] Preferably, the connecting seat includes two first connecting plates and two second connecting plates. The two first connecting plates and the two second connecting plates are all fixedly connected to the side plates. First shaft holes corresponding to the first pins are opened on the upper sides of the two first connecting plates. A pin cylinder is arranged between the two first connecting plates, and the pin cylinder is fixedly connected to the side of the upper car plate close to the side plate. The first pin is rotatably inserted through the pin cylinder and the first shaft hole, and nuts are threadedly installed at both ends of the first pin. Second shaft holes corresponding to the second pins are opened on the lower sides of the two first connecting plates and the two second connecting plates. Two connecting rods are arranged between the two second connecting plates, and the two connecting rods are fixedly connected to the side of the connecting device close to the side plate. There are two second pins, and the two second pins are respectively rotatably inserted through the two connecting rods and the second shaft holes, and nuts are threadedly installed at both ends of the two second pins.
[0006] Preferably, an anti-slip feature is provided on the upper surface of the upper car plate.
[0007] Preferably, a pulley is rotatably connected to the outside of the upper car plate through a third pin. When the upper car plate descends, the pulley first touches the ground, and the two side upper car plates can move outward.
[0008] Preferably, the pin cylinder is welded to the upper car plate.
[0009] Preferably, steel rings are arranged at both ends of the upper car plate, and it is convenient to lift the upper car plate through the steel rings.
[0010] Compared with the prior art, the beneficial effects of the present utility model are:
[0011] After the vehicle reaches the lifting position above the top plate through the boarding plate, during the lifting process, the tail end of the boarding plate automatically sinks under its own gravity. The two bearing plates slide within the rectangular sliding space and contact the front ends of the two brackets, fixing and supporting the boarding plate at an angle of about 66 degrees with the horizontal direction. This angle range can prevent the boarding plate from contacting the vehicle tires during the lifting process when lifting a vehicle with a relatively small wheelbase, preventing the boarding plate from jamming the vehicle tires, improving the stability of the lifting process, and increasing the versatility of the lifting equipment.

The lower part of the connecting seat is rotatably connected to a connecting device 6 through a second pin 5. A cross plate 7 is arranged at the bottom of the boarding plate 4. Two brackets 8 are symmetrically arranged on both sides of the cross plate 7. A sliding space is formed between the two brackets 8 and the boarding plate 4. Two bearing plates 9 are arranged at both ends of the connecting device 6. The two bearing plates 9 are respectively slidably connected in the two sliding spaces. A support rod 10 is arranged on the side of the connecting device 6 away from the connecting seat. The support rod 10 can be detachably supported on the side wall of the cross plate 7.
[0021] The connecting seat includes two first connecting plates 11 and two second connecting plates 12. The two first connecting plates 11 and the two second connecting plates 12 are both fixedly connected to the side plate 2. First shaft holes conforming to the first pin 3 are opened on the upper sides of the two first connecting plates 11. A pin cylinder 13 is arranged between the two first connecting plates 11. The pin cylinder 13 is fixedly connected to the side of the boarding plate 4 close to the side plate 2. The first pin 3 is rotatably inserted through the pin cylinder 13 and the first shaft hole. Nuts are threadedly installed at both ends of the first pin 3. Second shaft holes conforming to the second pin 5 are opened on the lower sides of the two first connecting plates 11 and the two second connecting plates 12. Two connecting rods 14 are arranged between the two second connecting plates 12. The two connecting rods 14 are fixedly connected to the side of the connecting device 6 close to the side plate 2. There are two second pins 5. The two second pins 5 are respectively rotatably inserted through the two connecting rods 14 and the second shaft holes.
