Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of shipbuilding, and in particular to a vehicle lifting platform with a folding ramp. Background Art

[0002] like Figure 1 and Figure 2 As shown, when a large vehicle enters a ro-ro ship, it often needs to be transported to the upper deck 3 or the lower deck 2 by a lifting platform 4, and the lifting platform itself has a thickness of about 700 mm. Figure 1 and Figure 2 There are usually two methods for the lifting platform 4 to eliminate the influence of its own height: method (1), such as Figure 1 As shown, a large groove 5 is dug on the lower deck 2 to store the lifting platform 4, so that the upper surface of the lifting platform 4 is flush with the upper surface of the lower deck 2; or method (2), such as Figure 2 As shown, a shorter slope is arranged on the lower deck 2 to cooperate with the lifting platform. In this way, the vehicle can be driven onto the platform and then lifted.

[0003] However, both of the above methods have certain defects. As for method (1), a large groove 5 is dug on the middle deck to store the lifting platform 4. During navigation, when the top deck is open or the lower surface of another cabin, in order to ensure watertight separation from the space on the middle deck, the lifting platform 4 needs to be parked below the upper deck. At this time, the large groove 5 is exposed and the vehicle cannot be parked. As for method (2), the prior art 2 still needs to dig a small groove 6 on the middle deck and set a shorter movable ramp 7 or 7' (the inclination angle of the movable ramp 7 or 7' is adjusted by the actuator 8), but when the lifting platform 4 rises to the position below the upper deck, the small groove 6 will also be exposed, which still hinders the parking of the vehicle.

[0004] Therefore, the above two existing solutions will cause space loss and affect the height of the next floor. The existence of the groove not only affects the structural strength of the deck, but also makes it easy for water to accumulate and difficult to clean. Summary of the invention

[0005] The embodiment of the utility model provides a vehicle lifting platform with a folding ramp, which can avoid grooving on the deck and make effective use of the deck area.

[0026] The beneficial effect of the vehicle lifting platform with folding ramp provided by the utility model is that it not only avoids the setting of grooves and improves the strength of the deck, but also does not affect the use of the space on the lower deck when the lifting platform rises to the upper deck, thereby improving the space utilization rate.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The technical solution of the present utility model is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0040] like Figures 3 to 7As shown, the vehicle lifting platform with a foldable ramp provided by the utility model comprises: a platform body 4, a first ramp 9, a second ramp 10, a first actuating device 11 and a second actuating device 12.

[0041] The first ramp 9 is rotatably arranged on the platform body 4. One rotatable arrangement is: connected by a hinge.

[0042] The first actuating device is on the platform body and connected to the first ramp, and is used to move the first ramp from Figure 3 The expanded state shown moves to Figure 6 The folding process state, finally Figure 7 fully folded state.

[0043] A possible first actuating device includes: a first rolling motor, a first steel cable, a second rolling motor, and a second steel cable. The first rolling motor is arranged on the upper side of the platform body 4, and the second rolling motor is arranged on the lower side of the platform body 4. One end of the first steel cable is fixed to the first rolling motor, and the other end is connected to the upper side of the first ramp. One end of the second steel cable is fixed to the second rolling motor, and the other end is connected to the lower side of the first ramp. When the first rolling motor and the second rolling motor rotate, the first ramp 9 can be lifted upward or bent downward by the first steel cable and the second steel cable according to the different rotation directions.

[0044] The second ramp 10 is rotatably arranged on the first ramp 9. A possible rotatable arrangement is: connected by a hinge, and a limiting structure is also provided at the position where the second ramp cooperates with the first ramp 9, so that when the first rolling motor (cooperating with the second rolling motor, the same below) tightens the first steel cable, the first ramp 9 and the second ramp 10 are in a Figure 3 when the first rolling motor releases the first cable, the first ramp 9 and the second ramp 10 bend downward.

[0045] The second actuating device is disposed on the first ramp 9 and connected to the second ramp 10 .

[0046] A possible second actuating device is: a straight rod motor (existing technology), when the straight rod motor is in a retracted state, it is used to drive the first ramp and the second ramp from Figure 3 Exercise to Figure 6 , and eventually move to Figure 7 When the straight rod motor is in the extended state, it is used to drive the first ramp and the second ramp to gradually increase their deployment angles, and finally present Figure 3 The status shown in .

[0047] It should be noted that Figure 3 In the embodiment, the first actuating device 11 and the first actuating device 11' have opposite functions and are used in conjunction with each other. Figure 6For example, the difference between the first actuating device 11, the first actuating device 11', and the first actuating device 11" is explained: 11 is loosened, 11' is tightened to the position of 11", the first ramp 9 rotates downward to the position of the first ramp 9', and the second ramp 10 is gradually bent to the position of the second ramp 10' under the action of the second actuating device. Here, 11', 11", 9, 9', 10, 10', respectively, refer to the same component in different positions, and this is to illustrate how the first ramp 9 and the second ramp 10 move.

[0048] In this embodiment, the first ramp 9 and the second ramp 10 are provided because, on the one hand, the platform body 4 is relatively high, and on the other hand, the first ramp 9 and the second ramp 10 are foldable for easy storage.

[0049] It can be found that the above solution not only avoids the setting of the groove and improves the strength of the deck, but also does not affect the use of the space on the lower deck when the lifting platform 4 rises to the upper deck 3, thereby improving the space utilization rate.

[0050] In a feasible solution, it also includes: fixing the small slope. Figure 3 , Figure 4 and Figure 5 As shown, a fixed small slope is set in the uphill area of ​​the platform body ( Figure 3 The left side of the ramp starts to go uphill), and when the second ramp is in the unfolded state, the fixed small slope is adjacent to the second ramp 10.

[0051] This technical solution is adopted to avoid impact and damage to the second ramp 10.

[0052] In a feasible solution, the fixed small slope is in the shape of a spliced ​​"M" (such as Figure 5 As shown), and the side close to the platform body is made of elastic material, that is, Figure 5 The part indicated by the reference numeral 13 is made of elastic material.

[0053] This technical solution is adopted in order to cooperate with the second ramp 10 .

[0054] In a feasible solution, the side of the fixed small slope away from the platform body is made of a rigid wear-resistant material, that is, Figure 5 The part indicated by the reference numeral 14 is made of rigid wear-resistant material.

[0055] This technical solution is adopted in order to withstand the impact force of the vehicle.

[0056] In a feasible solution, the first actuating device includes: a first traction motor, a first traction cable and a guide wheel.

[0057] The traction motor is arranged on the platform body 4 .

[0058] The first traction steel cable is fixed on the guide wheel.

[0059] One end of the first traction cable is connected to the rotating shaft of the traction motor, and the other end is connected to the first ramp 9.

[0060] This technical solution is adopted in order to provide a mechanism capable of remotely adjusting the position of the first ramp 9 .

[0061] In a feasible solution, the second actuating device includes: a hydraulic cylinder and a telescopic rod.

[0062] The hydraulic cylinder is rotatably arranged on the first ramp 9 (such as hinged or rotating axis).

[0063] The telescopic rod is arranged in the hydraulic cylinder, and the hydraulic cylinder is used for driving the telescopic rod to extend and retract.

[0064] The distal end of the telescopic rod is rotatably connected to the second ramp.

[0065] The first ramp 9 is driven to move by a hydraulic cylinder and a telescopic rod, which belongs to the prior art. However, the hydraulic cylinder moves relatively smoothly, which is beneficial to reducing impact noise.

[0066] In one possible solution, Figure 7 As shown, a receiving groove (not numbered in the figure) is further provided at the bottom of the platform body 4, and the first ramp 9 and the second ramp 10 can be received in the receiving groove in the folded state.

[0067] This technical solution is used to make the occupied space smaller.

[0068] In a feasible solution, it further includes: a third actuating device, which is disposed in the accommodating groove and is rotatably connected to the first ramp.

[0069] A third action device is: a lifting motor is arranged in the receiving groove, a steel cable is wound around the rotating shaft of the lifting motor, and the lifting motor drives the first ramp 9 to move up and down.

[0070] This technical solution is adopted to prevent the first ramp from being loosely constrained and shaking up and down.

[0071] In a feasible solution, it also includes: an alarm device, which is arranged on the platform body 4.

[0072] A possible alarm device is an audible and visual alarm device (existing technology), which is used to warn the user when the platform body 4 is working.

[0073] In a feasible solution, it also includes: a monitoring device and a controller, and the monitoring device and the alarm device are electrically connected to the controller respectively. A possible monitoring device is an infrared monitor, which is used to detect whether there is a person under the lifting platform 4 by monitoring the human body temperature. If there is a person, the controller will warn the user through the alarm device.

[0074] This technical solution is adopted to improve safety.

[0076] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
