Description

Technical Field

[0001] The utility model relates to a maintenance platform, in particular to a foldable lifting maintenance platform. Background Art

[0002] In a lifting maintenance platform, the lifting of the lifting platform is often achieved by a scissor mechanism, but the fence on the lifting platform is often fixed. This causes the overall height of the maintenance platform to be higher when it is in the storage state, increasing the space occupied by the maintenance platform;

[0003] In summary, how to realize the storage of the fence on the maintenance platform, reduce the overall height of the maintenance platform, and facilitate the storage of the maintenance platform has become a problem that researchers in this field urgently need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to realize the storage of the fence on the maintenance platform and reduce the overall height of the maintenance platform;

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The utility model is a foldable lifting inspection platform, comprising: a base; a lifting platform, the bottom of which is connected to the base via a scissor assembly; a first fence, which is controlled by a first drive assembly to rotate and is arranged on one side of the width of the lifting platform; a second fence, which is controlled by a second drive assembly to rotate and is arranged on one side of the length of the lifting platform; when the inspection platform is in an inspection state, the first fence and the second fence are rotated to a vertical state; when the inspection platform is in a storage state, the first fence and the second fence are rotated to a horizontal stacking state;

[0007] In this solution, the lifting and lowering of the lifting platform is achieved through a scissor-type assembly. The first fence can be flipped under the control of the first drive assembly, that is, the first fence can be flipped from a vertical state to a horizontal state; similarly, the second fence can be flipped under the control of the second drive assembly, that is, the second fence can be flipped from a vertical state to a horizontal state. When both fences are in a horizontal state, the second fence and the first fence are arranged up and down, thereby realizing the storage of the fences and reducing the overall height of the maintenance platform.

[0008] To illustrate the specific structure of the first drive assembly, the present invention adopts the first drive assembly comprising: a first electric cylinder, which is arranged on one side of the length side of the lifting platform; a first hinged seat, which is fixed to one side of the width side of the lifting platform and is hinged to the first ear at the bottom of the first fence; a first fixed shaft, to which the side of the first fence is fixed; a first connecting rod, one end of which is hinged to the piston rod of the first electric cylinder and the other end is fixedly connected to the end of the first fixed shaft;

[0009] In this solution, the first support ear at the bottom of the first fence is hinged to the first hinged seat on the side of the lifting platform, thereby realizing the rotation of the first fence relative to the lifting platform; the first electric cylinder is started, the piston rod of the first electric cylinder is extended, and the first fixed shaft is driven to rotate through the first connecting rod, driving the first fence to rotate, and switching the first fence between vertical or horizontal states.

[0010] To illustrate the specific structure of the second drive assembly, the second drive assembly adopted by the present invention includes: a second hinged seat, which is fixed to one side of the length of the lifting platform and is hinged to the second ear at the bottom of the second fence; a second cylinder, which is arranged at the bottom of the lifting platform; an arc-shaped connecting rod, one end of which is connected to the bottom of the second fence and the other end of which is hinged to the output end of the second cylinder;

[0011] In this solution, the second support ear at the bottom of the second fence is hinged to the second hinged seat on the side of the lifting platform, thereby realizing the rotation of the second fence relative to the lifting platform; the second cylinder is started, and the piston rod of the second cylinder is extended, driving the second fence to rotate through the arc-shaped connecting rod, thereby switching the second fence between vertical or horizontal states.

[0012] In order to limit the rotation angle of the first fence and the second fence, the present invention adopts a first sensor provided on the first hinge seat and a second sensor provided on the second hinge seat; when the first fence rotates to contact the first sensor, the first fence is in a vertical state; when the second fence rotates to contact the second sensor, the second fence is in a vertical state;

[0013] When the first fence rotates to contact the first sensor and the second fence rotates to contact the second sensor, the first sensor controls the first electric cylinder to stop moving, and the second sensor controls the second air cylinder to stop moving. At this time, the first fence and the second fence are in a vertical working state.

[0014] In order to convert the linear motion of the first electric cylinder into the rotational motion of the first fence, and to convert the linear motion of the second pneumatic cylinder into the rotational motion of the second fence, the present invention adopts that the cylinder body of the first electric cylinder and the cylinder body of the second pneumatic cylinder are both hinged to the lifting platform;

[0015] When the first electric cylinder is working, the angle of the first electric cylinder and the lifting platform will be adjusted due to the articulation. The rotation of the first fence is achieved by adjusting the angle of the cylinder body and the lifting platform and extending the piston rod of the first electric cylinder. Similarly, when the second electric cylinder is working, the angle of the second electric cylinder and the lifting platform will be adjusted due to the articulation. The rotation of the second fence is achieved by adjusting the angle of the cylinder body and the lifting platform and extending the piston rod of the second electric cylinder.

[0016] In order to avoid interference between the first fence and the second fence during the storage process, the utility model adopts a method in which when the second fence is rotated to a horizontal state, a space for accommodating the first fence is formed between the second fence and the lifting platform;

[0017] In this solution, since the first support leg is vertically connected to the bottom of the first fence and the second support leg is obliquely connected to the bottom of the second fence, the first fence is rotated to a horizontal state, the first fence is in contact with the lifting platform, and the second fence is rotated to a horizontal state. There is a gap between the second support leg and the lifting platform in the height direction, and the distance of the gap is greater than the thickness of the first fence. In this way, the first fence and the second fence are arranged up and down when they are stored, avoiding interference between the first fence and the second fence when they are stored.

[0018] The beneficial effects of the present invention are as follows: the present invention is a foldable lifting inspection platform, the lifting of which is achieved through a scissor-type assembly. The first fence can be flipped under the control of the first driving assembly, that is, the first fence is flipped from a vertical state to a horizontal state; similarly, the second fence can be flipped under the control of the second driving assembly, that is, the second fence is flipped from a vertical state to a horizontal state. When both fences are in a horizontal state, the second fence and the first fence are arranged up and down, thereby realizing the storage of the fences and reducing the overall height of the inspection platform.

DETAILED DESCRIPTION

[0025] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0026] like Figure 1 、 2 As shown, the utility model is a foldable lifting maintenance platform, comprising: a base 1; a lifting platform 2, the bottom of which is connected to the base 1 through a scissor assembly 3; a first fence 4, which is controlled by a first drive assembly to rotate and is arranged on one side of the width side of the lifting platform 2; a second fence 5, which is controlled by a second drive assembly to rotate and is arranged on one side of the length side of the lifting platform 2; when the maintenance platform is in the maintenance state, the first fence 4 and the second fence 5 are rotated to a vertical state; when the maintenance platform is in the storage state, the first fence 4 and the second fence 5 are rotated to a horizontal stacking state;

[0027] In this solution, the lifting and lowering of the lifting platform is achieved through a scissor-type assembly. The first fence can be flipped under the control of the first drive assembly, that is, the first fence can be flipped from a vertical state to a horizontal state; similarly, the second fence can be flipped under the control of the second drive assembly, that is, the second fence can be flipped from a vertical state to a horizontal state. When both fences are in a horizontal state, the second fence and the first fence are arranged up and down, thereby realizing the storage of the fences and reducing the overall height of the maintenance platform.

[0028] like Figure 1 、 3 As shown, in order to illustrate the specific structure of the first drive assembly, the present invention adopts the first drive assembly including: a first electric cylinder 6, which is arranged on one side of the length side of the lifting platform 2, and the length direction of the first electric cylinder is parallel to the length direction of the lifting platform 2; a first hinged seat 7, which is fixed on one side of the width side of the lifting platform 2 and is hinged to the first support ear 8 at the bottom of the first fence 4; a first fixed shaft 9, the side of the first fence 4 is fixed with the first fixed shaft 9; a first connecting rod 10, one end of which is hinged to the piston rod of the first electric cylinder 6, and the other end is fixedly connected to the end of the first fixed shaft 6;

[0029] In this solution, the first support ear at the bottom of the first fence is hinged to the first hinged seat on the side of the lifting platform, thereby realizing the rotation of the first fence relative to the lifting platform; the first electric cylinder is started, the piston rod of the first electric cylinder is extended, and the first fixed shaft is driven to rotate through the first connecting rod, driving the first fence to rotate, and switching the first fence between vertical or horizontal states.

[0030] like Figure 2 、 4As shown, in order to illustrate the specific structure of the second drive assembly, the second drive assembly adopted by the present invention includes: a second hinged seat 11, which is fixed to one side of the length side of the lifting platform 2 and is hinged to the second lug 12 at the bottom of the second fence 5; a second cylinder, which is arranged at the bottom of the lifting platform 2; an arc-shaped connecting rod 13, one end of which is connected to the bottom of the second fence 5, and the other end of which is hinged to the output end of the second cylinder;

[0031] In this solution, the second support ear at the bottom of the second fence is hinged to the second hinged seat on the side of the lifting platform, thereby realizing the rotation of the second fence relative to the lifting platform; the second cylinder is located at the bottom of the lifting platform, and the length direction of the second cylinder is parallel to the width direction of the lifting platform. When the second cylinder is started, the piston rod of the second cylinder extends, and the second fence is driven to rotate through the arc-shaped connecting rod, thereby switching the second fence between vertical or horizontal states.

[0032] like Figure 3 、 4 As shown, in order to limit the rotation angle of the first fence and the second fence, the utility model adopts a first sensor 14 provided on the first hinge seat 7 and a second sensor 15 provided on the second hinge seat 11; when the first fence 4 rotates to contact the first sensor 14, the first fence 4 is in a vertical state; when the second fence 5 rotates to contact the second sensor 15, the second fence 5 is in a vertical state;

[0033] When the first fence rotates to contact the first sensor and the second fence rotates to contact the second sensor, the first sensor controls the first electric cylinder to stop moving, and the second sensor controls the second air cylinder to stop moving. At this time, the first fence and the second fence are in a vertical working state.

[0034] like Figure 3 、 4 As shown, in order to convert the linear motion of the first electric cylinder into the rotational motion of the first fence, and to convert the linear motion of the second pneumatic cylinder into the rotational motion of the second fence, the present invention adopts that the cylinder body of the first electric cylinder 6 and the cylinder body of the second pneumatic cylinder are both hinged to the lifting platform 2;

[0035] When the first electric cylinder is working, the angle of the first electric cylinder and the lifting platform will be adjusted due to the articulation. The rotation of the first fence is achieved by adjusting the angle of the cylinder body and the lifting platform and extending the piston rod of the first electric cylinder. Similarly, when the second electric cylinder is working, the angle of the second electric cylinder and the lifting platform will be adjusted due to the articulation. The rotation of the second fence is achieved by adjusting the angle of the cylinder body and the lifting platform and extending the piston rod of the second electric cylinder.

[0036] like Figure 4As shown, in order to avoid interference between the first fence and the second fence during the storage process, the utility model adopts that when the second fence 5 is rotated to a horizontal state, a space is formed between the second fence 5 and the lifting platform 2 to accommodate the thickness of the first fence 4;

[0037] In this solution, since the first support leg is vertically connected to the bottom of the first fence and the second support leg is obliquely connected to the bottom of the second fence, the first fence is rotated to a horizontal state, the first fence is in contact with the lifting platform, and the second fence is rotated to a horizontal state. There is a gap between the second support leg and the lifting platform in the height direction, and the distance of the gap is greater than the thickness of the first fence. In this way, the first fence and the second fence are arranged up and down when they are stored, avoiding interference between the first fence and the second fence when they are stored.
