Description

Technical Field

[0001] The present invention relates to the field of mechanical fall prevention, and in particular to a vertical lifting device, a tooth comb elevator and a tower library. Background Art

[0002] As a new type of parking facility, parking garages are widely used due to their space-saving advantages. These garages use a lift to raise and lower vehicles, allowing for easy entry and exit. However, after prolonged use, the suspension mechanism of the lift can break, posing a safety hazard and causing property damage.

[0003] While various types of fall prevention devices exist in the prior art, the unique structure of tower elevators and their need for space conservation necessitate a need for a fall prevention device that is simple in structure, takes up minimal space, and requires no external force, suitable for use with elevators, particularly comb elevators. Furthermore, because these elevators carry heavy vehicles, fall prevention devices also require rapid response, but no existing fall prevention device is fully suitable for tower elevators. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a vertical lifting device suitable for a tower elevator, a tooth comb elevator and a tower elevator.

[0005] The technical solution of the present invention for solving the above technical problems is as follows: a vertical lifting device, comprising a guide column, an elevator lifting column and an anti-falling baffle, the top of the elevator lifting column is suspended by a hanging part, and the elevator lifting column is vertically lifted relative to the guide column; the anti-falling device comprises an anti-falling baffle, at least one anti-falling block and a limit block, the plane where the anti-falling baffle is located is parallel to one side wall of the elevator lifting column; the two ends of the anti-falling baffle are respectively a pulling end and a limiting end, and the middle part is rotatably connected to one side wall of the elevator lifting column; the pulling end is fixedly installed with a device to provide an upward force for the anti-falling baffle The first pull rod can change the pulling force or disconnect it when the elevator lifting column falls, and a tension spring can provide downward tension; the anti-fall block is fixedly mounted on the edge of one side wall of the guide column, and the anti-fall block extends outside the guide column and is perpendicular to the anti-fall baffle; the limit block is fixedly mounted on one side wall of the elevator lifting column and is located on the upper side of the anti-fall baffle; the anti-fall block and the limit block are close to the limit end of the anti-fall baffle, and when the elevator lifting column falls, the limit end of the anti-fall baffle rotates to the limit end and is limited between the anti-fall block and the limit block.

[0006] The beneficial effect of this embodiment is that the anti-fall baffle can be limited by the limit block and the anti-fall block through the rotation of the anti-fall baffle, thereby achieving the technical effect of preventing falling.

[0007] Furthermore, the angle between the side edge of the limiting end and the lower edge of the anti-fall baffle is an acute angle;

[0008] The limiting method of the anti-falling block and the limiting block is that the limiting end of the anti-falling baffle rotates upward, and the lower edge is placed on the upper edge of the anti-falling block, and the upper edge of the limiting end is limited by the lower edge of the limiting block.

[0009] The beneficial effect of adopting the above-mentioned further technical method is that both of them simultaneously limit the anti-falling baffle, so that the anti-falling baffle can be stably located between the anti-falling block and the limit block.

[0010] Furthermore, the anti-falling baffle is rotatably mounted on a side wall of the lifting column of the elevator through a core shaft; the core shaft is located in the middle of the anti-falling baffle.

[0011] The beneficial effect of adopting the above-mentioned further technical method is that the force application position of the tension spring can be arranged symmetrically with the positions of the anti-fall block and the limit block, thereby further increasing the stability of the limit.

[0012] Furthermore, the upper and lower parts of the pulling end of the anti-fall baffle are respectively connected to one end of the first pull rod and one end of the tension spring; the other end of the first pull rod is fixed on the suspension part, and the other end of the tension spring is fixed on the lifting column of the elevator.

[0013] The beneficial effect of adopting the above-mentioned further technical method is that the fixation of the first pull rod and the tension spring is made more stable, thereby preventing the problem of the anti-fall device failing due to the falling of the first pull rod and the tension spring.

[0014] Furthermore, one end of the first pull rod is easily disconnected from the pulling end of the anti-fall baffle via a cotter pin.

[0015] The beneficial effect of adopting the above-mentioned further technical method is that: since the anti-fall device can only play a role after the tension of the first pull rod disappears, an easy-to-break cotter pin is provided, which can be quickly disconnected when a fall occurs, so that the tension of the first pull rod disappears quickly, thereby enabling the anti-fall device to play a role in time.

[0016] Furthermore, a first pull rod connector is fixedly mounted on the suspension portion, and the first pull rod is fixedly connected to the suspension portion via the first pull rod connector.

[0017] The beneficial effect of adopting the above further technical aspect is that the first pull rod can be further stably fixed on the suspension part by connecting the first pull rod connector to the suspension part.

[0018] Furthermore, the tension spring is fixed to the lifting column of the elevator through the second pull rod and the second pull rod connecting piece; one end of the second pull rod is rotatably connected to the tension spring, and the other end is inserted into the hole on the second pull rod connecting piece, and the two are detachably connected; any outer side wall of the second pull rod connecting piece is fixed to the lifting column of the elevator.

[0019] The beneficial effect of adopting the above-mentioned further technical method is that the connection position of the tension spring and the lifting column of the elevator can be adjusted, so that the tension degree of the tension spring can be adjusted according to actual needs, and then the size of the tensioning force can be adjusted.

[0020] A tooth comb elevator of the present invention includes at least one vertical lifting device and a load-bearing device, and is characterized in that the vertical lifting device is provided with an anti-falling device as described above, and the load-bearing device is fixed on the lifting column of the elevator.

[0021] The beneficial effect of adopting the above technical method is that the anti-falling device can prevent the load-bearing device from falling, thereby increasing the safety of the tooth comb lifter.

[0022] Furthermore, it comprises four vertical lifting devices, each of which is arranged at a corner of the comb lifter; and the four vertical lifting devices are lifted and lowered simultaneously.

[0023] The beneficial effect of adopting the above-mentioned further technical method is that the safety of the comb lifter is further increased.

[0024] A tower library of the present invention comprises the comb elevator as described above.

[0025] The beneficial effect of adopting the above-mentioned further technical method is that the safety of the tower library is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] like Figures 1-2 As shown, the vertical lifting device of the present invention is arranged on the vertical lifting device, and the vertical lifting device includes a guide column 13 and an elevator lifting column 14. The top of the elevator lifting column 14 is suspended by a suspension part, and the elevator lifting column 14 is vertically lifted relative to the guide column 13; the anti-falling device includes an anti-falling baffle 1, the plane where the anti-falling baffle 1 is located is parallel to the side wall of the elevator lifting column 14, and is rotatably installed on the side wall of the elevator lifting column 14; the anti-falling baffle 1 includes a pulling end and a limiting end; the pulling end is fixedly installed to provide a first pull rod for the anti-falling baffle 1 to provide an upward pulling force 4, and a tension spring 7 that provides downward tension; an acute angle is formed between the side edge and the lower edge of the limiting end; at least one anti-falling block 2 is fixedly installed on the edge of one side wall of the guide column 13, and the anti-falling block 2 extends outside the guide column 13 and is perpendicular to the anti-falling baffle 1; a limiting block 3 is fixedly installed on one side wall of the elevator lifting column 14 and is located on the upper side of the anti-falling baffle 1; the anti-falling block 2 and the limiting block 3 are close to the limiting end of the anti-falling baffle 1; the distance between the upper edge of the anti-falling block 2 and the lower edge of the limiting block 3 in the vertical direction is greater than the width of the anti-falling baffle 1, which is used to limit the limiting end between the two.

[0038] Preferably, there are multiple anti-falling blocks 2, and the multiple anti-falling blocks 2 are arranged at intervals in the vertical direction.

[0039] The anti-fall block 2 of the present invention is not elastic and is made of steel plate; the anti-fall block 2 and the limit block 3 work together to limit the anti-fall baffle 1 between the anti-fall block 2 and the limit block 3 when the elevator lifting column 14 falls, so that the elevator lifting column 14 is restricted and will not fall a long distance; when the elevator lifting column 14 is lifted and lowered normally, the anti-fall baffle 1 does not contact the anti-fall block 2. Only when the elevator lifting column 14 falls, the anti-fall baffle 1 turns to a horizontal state under the pulling force of the tension spring 7, and is limited between the two by the anti-fall block 2 and the limit block 3, so that the elevator lifting column 14 no longer continues to fall. During this process, the tension spring 7 does not provide support for the anti-fall baffle 1.

[0040] When the lifting plate 1 is lifted up, the lifting device 10 is lifted and the support 14 is lifted and the support 10 is lowered, so that the lifting plate 10 can be lifted and the support 10 is lowered.

[0041] like Figures 1-2 As shown, in the above embodiment, preferably, the limiting method of the anti-fall block 2 and the limit block 3 is that the lower edge of the limiting end is overlapped with the upper edge of the anti-fall block 2, and the upper edge of the limiting end is limited by the lower edge of the limit block 3; both of them limit the anti-fall baffle 1 at the same time, so that the anti-fall baffle 1 can be stably located between the anti-fall block 2 and the limit block 3.

[0042] like Figures 1-2 As shown, in the above embodiment, preferably, the anti-fall baffle 1 is rotatably mounted on a side wall of the elevator lifting column 14 through a core shaft 10; the core shaft 10 is located in the middle of the anti-fall baffle 1; so that the force application position of the tension spring 7 can be symmetrically arranged with the positions of the anti-fall block 2 and the limit block 3, further increasing the stability of the limit.

[0043] like Figures 1-2 As shown, in the above embodiment, preferably, the core shaft 10 is located between the anti-fall block 2 and the limit block 3 in the vertical direction.

[0044] like Figures 1-2As shown, in the above embodiment, preferably, the upper and lower parts of the pulling end of the anti-fall baffle 1 are respectively connected to one end of the first pull rod 4 and one end of the tension spring 7; the other end of the first pull rod 4 is fixed on the hanging part, and the other end of the tension spring 7 is fixed on the elevator lifting column 14; the first pull rod 4 and the tension spring 7 are fixed more firmly, preventing the problem of failure of the anti-fall device caused by the falling of the two.

[0045] like Figures 1 to 4 As shown, in the above embodiment, preferably, one end of the first pull rod 4 is connected to the pulling end of the anti-fall baffle 1 by an easily disconnected cotter pin 6; since the anti-fall device can only function after the pulling force of the first pull rod 4 disappears, an easily disconnected cotter pin 6 is provided, which can be quickly disconnected when a fall occurs, so that the pulling force of the first pull rod 4 disappears quickly, thereby enabling the anti-fall device to function in time.

[0046] like Figures 1 to 4 As shown, in the above embodiment, preferably, a first pull rod connector 5 is fixedly installed on the suspension part, and the first pull rod 4 is fixedly connected to the suspension part through the first pull rod connector 5; by being connected to the suspension part through the first pull rod connector 5, the first pull rod 4 can be further stably fixed on the suspension part.

[0047] like Figures 1 to 4 As shown, in the above embodiment, preferably, the third pull rod 11 is installed on the first pull rod connector 5 , and the first pull rod 4 and the third pull rod 11 are hinged together by screws 12 .

[0048] like Figures 1 to 4 As shown, in the above embodiment, preferably, the tension spring 7 is fixed to the elevator lifting column 14 through the second pull rod 8 and the second pull rod connector 9; one end of the second pull rod 8 is rotatably connected to the tension spring 7, and the other end is inserted into the hole on the second pull rod connector 9, and the two are detachably connected; any outer side wall of the second pull rod connector 9 is fixed to the elevator lifting column 14; by adjusting the length of the second pull rod 8 inserted into the second pull rod connector 9 and fixing it with bolts, the connection position of the tension spring 7 and the elevator lifting column 14 can be adjusted, so that the tension degree of the tension spring 7 can be adjusted according to actual needs, and then the magnitude of the tensioning force can be adjusted.

[0049] In the above embodiment, preferably, the suspension portion includes one of a unilateral or bilateral chain, a steel cable, and a pull rope.

[0050] The specific anti-falling process of the vertical lifting device of the present invention is divided into the following situations:

[0051] like Figures 5-6As shown, when the position where the suspension part is broken is below the connection position between the first pull rod 4 and the suspension part, the first pull rod 4 becomes the only connecting structure, and the gravity of the elevator lifting column 14 causes the cotter pin 6 to be disconnected, and the pulling force of the first pull rod 4 on the anti-fall baffle 1 disappears. The downward tension provided by the tension spring 7 causes the pulling end of the anti-fall baffle 1 to move downward, thereby driving the anti-fall baffle 1 to rotate, so that the limit end of the anti-fall baffle 1 slides between the anti-fall block 2 and the limit block 3 to achieve limiting; at this time, the elevator lifting column 14 can stop falling, thereby achieving the anti-fall effect.

[0052] like Figure 7 As shown, when the position where the suspension part breaks is above the connection position between the first pull rod 4 and the suspension part, the part below the connection position between the first pull rod 4 and the suspension part loses the upward pulling force, so that the pulling force applied by the first pull rod 4 to the anti-fall baffle 1 is reduced, and the downward tension provided by the tension spring 7 can still move the pulling end of the anti-fall baffle 1 downward, and achieve the same anti-fall effect as the above process.

[0053] In particular, when the suspension part is a double-sided chain, steel cable or pull rope, when the position where the suspension part breaks is above the connection position between the first pull rod 4 and the suspension part, since the connection position between the first pull rod 4 and the suspension part is located on one side of the suspension part, an overload occurs, that is, under the action of the first pull rod 4's own gravity, the tension applied to the anti-fall baffle 1 is further reduced.

[0054] It should be noted that in the above-mentioned anti-falling process, the disappearance or reduction of the pulling force of the first pull rod 4 on the anti-falling baffle 1 occurs instantaneously. At the same time, the pulling of the tension spring 7 and the rotation of the anti-falling baffle 1 until its limit end is limited all occur quickly in succession. In such a process, the elevator lifting column 14 and the vehicle carried thereon will not generate enough impulse to damage the anti-falling block 2 and the limit block 3, so the above-mentioned limiting process can be realized.

[0055] Moreover, the displacement of the elevator lifting column 14 relative to the guide column 13 is small, and the plurality of anti-falling blocks 2 and the limit blocks 3 can limit the elevator lifting column 14 before it falls completely.

[0056] like Figure 8 As shown, a tooth comb elevator of the present invention includes at least one vertical lifting device and a load-bearing device. The vertical lifting device is provided with an anti-falling device as described above, and the load-bearing device is fixed on the elevator lifting column 14; during the lifting process of the tooth comb elevator, if a fall occurs, the anti-falling device can effectively prevent further falling, thereby effectively increasing the safety of the tooth comb elevator.

[0057] The above-mentioned tooth comb elevator includes four vertical lifting devices, each of which is arranged at a corner of the tooth comb elevator; the four vertical lifting devices are lifted and lowered simultaneously; if a fall occurs, the anti-fall device on each vertical lifting device can simultaneously prevent further falling, further increasing the safety of the tooth comb elevator.

[0058] A tower library of the present invention comprises the comb elevator as described above.

[0059] The anti-falling device of the present invention has a simple structure and can prevent the elevator from falling without adding other power mechanisms; at the same time, the anti-falling device of the present invention also has the advantages of easy installation, rapid response and stable limiting.
