Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically, to an intelligent construction elevator door limiting mechanism. Background Technology

[0002] Construction hoists are commonly used transportation equipment in modern construction engineering operations. The hoist cage is an important component of this equipment, and the smooth opening of the hoist cage door is a necessary guarantee for the speed and safety of hoist transportation.

[0003] Chinese utility model patent CN211871117U discloses a hoist cage with an adjustable counterweight door, comprising a cage body and an integrated hoist door. Sliding rods are provided on both sides of the integrated hoist door. Two door wheels are provided on the upper end of the cage body, respectively located on both sides of the integrated hoist door and cooperating with the sliding rods. Fixed pulleys are provided on the upper end of the cage body. A steel wire rope is provided at the bottom of the integrated hoist door, passing around the fixed pulley. A counterweight is provided on the free end of the steel wire rope. A counterweight guide cylinder is provided on the cage body, and the counterweight is located inside the counterweight guide cylinder.

[0004] This structure uses a counterweight to offset the weight of the integrated lifting door, making it easier for workers to open and close the door. However, this type of cage door still has some problems, such as the door lock being manually opened and closed, which is inconvenient to operate. Utility Model Content

[0005] The main purpose of this utility model is to propose an intelligent construction hoist door limiting mechanism to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model proposes an intelligent construction hoist door limiting mechanism, the door comprising:

[0007] Door frame;

[0008] An upper door and a lower door are vertically mounted and slidably mounted on the door frame.

[0009] And a linkage unit, used to link the upper door and the lower door so that the upper door and the lower door can move synchronously and in opposite directions.

[0010] When the upper and lower doors are in a closed state, the limiting mechanism is used to limit the movement of the upper and / or lower doors.

[0011] In the above technical solution, the limiting mechanism further includes:

[0012] The first detection unit is used to detect the position of the upper door body on the door frame;

[0013] Locking components, installed on the door frame, are used to lock or unlock the upper door.

[0014] And a control unit, used to receive the signal detected by the first detection unit and control the state of the locking element;

[0015] Specifically, after the first detection unit detects that the upper door has moved to the designated position when it is closed, the control unit controls the locking mechanism to lock the upper door onto the door frame.

[0016] In any of the above technical solutions, the first detection unit is a limit switch located on the side of the door frame, and a first limiting hole is provided on the upper door body for the rod of the limit switch to be inserted.

[0017] In any of the above technical solutions, the locking component is an electromagnetic lock disposed on the side of the door frame, and a second limiting hole is provided on the upper door body for the rod of the electromagnetic lock to be inserted.

[0018] In any of the above technical solutions, the limiting mechanism further includes:

[0019] The second detection unit is electrically connected to the control unit and is used to detect the position of the upper door body on the door frame;

[0020] The second detection unit includes: a magnetic module, which is installed on the upper door body; and a magnetic field sensing module, which is installed on the door frame.

[0021] In this process, after the upper door moves to the designated position when it is closed, the magnetic module is aligned with the magnetic field sensing module. After the magnetic field sensing module senses the signal, it sends it to the control unit. The control unit then controls the locking mechanism to be in the locked state based on the signal.

[0022] In any of the above technical solutions, further, after the first detection unit and the second detection unit simultaneously detect that the upper door body has moved to the designated position when closed, the control unit controls the locking component to be in a locked state.

[0023] Beneficial effects: Compared with the existing technology, by setting up a first detection unit, a second detection unit and a locking component, it is possible to automatically lock the upper and lower doors after they are closed, and effectively reduce misjudgments when the upper and lower doors are closed.

[0037] Example 1:

[0038] like Figures 1-5 As shown, in this embodiment, a door structure for an intelligent construction hoist is proposed, including: a door frame 1; an upper door body 2 and a lower door body 3 that are arranged vertically and slidably disposed on the door frame 1; and a linkage part 4 for linking the upper door body 2 and the lower door body 3 so that the upper door body 2 and the lower door body 3 can move synchronously and in opposite directions.

[0039] The linkage part 4 includes: a wire guide wheel 41, which is located above the door frame 1; and a steel wire rope 42, which passes around the wire guide wheel 41, with one end located on the upper door body 2 and the other end located on the lower door body 3.

[0040] By dividing the door into two separate upper door body 2 and lower door body 3, and connecting the upper door body 2 and lower door body 3 with steel wire rope 42, this method not only solves the problem of single door being inconvenient to open, but also makes the upper door body 2 and lower door body 3 balanced under the action of steel wire rope 42 and guide wheel 41, without the need for additional counterweights, effectively reducing production costs.

[0041] It should be noted that the upper door body 2 and the lower door body 3 have similar weights to ensure their balance. Specifically, when the upper door body 2 and the lower door body 3 are in the closed state, with the guide wheel 41 as the fulcrum, the weight of the upper door body 2 plus the part of the steel wire rope 42 connected to it is greater than the weight of the lower door body 3 plus the part of the steel wire rope 42 connected to it, so that the door structure is in the closed state under its own weight. When the upper door body 2 and the lower door body 3 are opened to a certain degree, the weight of the upper door body 2 plus the part of the steel wire rope 42 connected to it is less than the weight of the lower door body 3 plus the part of the steel wire rope 42 connected to it, so that the door structure gradually opens to the maximum degree under its own weight.

[0042] It should be noted that, in order to ensure the stability of the upper door body 2 and the lower door body 3 when they move up and down, the linkage part 4 is set into two sets and symmetrically arranged on both sides of the door frame 1; and the top two sides of the door frame 1 are provided with guide wheel 12 frames 11, and guide wheels 12 are provided on the guide wheel 12 frames 11. The two sides of the upper door body 2 are embedded in the guide wheel 12 frames 11 and abut against the guide wheels 12.

[0043] It should be noted that the end of the steel wire rope 42 located on the upper door body 2 is located at the lower side of the upper door body 2; the end of the steel wire rope 42 located on the lower door body 3 is located at the upper side of the lower door body 3.

[0044] It should be noted that a baffle 13 is also provided on the upper side of the door frame 1 to limit the upward movement height of the first connection. The baffle 13 restricts the upward movement height of the upper door body 2.

[0045] In this embodiment, the optimized linkage part 4 further includes: a first connector 43, which is disposed at the lower side of the upper door body 2 and one end of which extends out of the door frame 1; and a second connector 44, which is disposed at the upper side of the lower door body 3 and one end of which extends out of the door frame 1.

[0046] One end of the wire rope 42 is located on the extended end of the first connector 43, and the other end is located on the extended end of the second connector 44.

[0047] To facilitate the connection of the wire rope 42 to the upper door body 2 and the lower door body 3, a first connector 43 and a second connector 44 are provided. Both the first connector 43 and the second connector 44 are sheet metal parts and are fixed by bolts or welding.

[0048] Example 2:

[0049] This embodiment is a further improvement based on Embodiment 1.

[0050] like Figure 1 , Figure 2 As shown, in this embodiment, a buffer pad 21 is provided between the upper door 2 and the lower door 3. When the upper door 2 and the lower door 3 are closed, the buffer pad 21 creates a certain gap between the upper door 2 and the lower door 3.

[0051] The buffer pads 21 are two in number and are elongated, and are set on both sides of the bottom of the upper door body 2. By setting the buffer pads 21, on the one hand, it can prevent the upper door body 2 and the lower door body 3 from colliding and generating noise; on the other hand, under the action of the buffer pads 21, there will be a certain gap between the upper door body 2 and the lower door body 3 after they are closed. This gap allows the staff to insert their hands between the upper door body 2 and the lower door body 3, thereby facilitating the application of external force to the upper door body 2 or the lower door body 3 to open them.

[0052] Example 3:

[0053] This embodiment is a further improvement based on any of the above embodiments.

[0054] like Figures 3-5 As shown, in this embodiment, it also includes a limiting mechanism 5, which is used to limit the movement of the upper door 2 and / or the lower door 3 when the upper door 2 and the lower door 3 are in the closed state.

[0055] The upper door 2 and lower door 3 are locked when closed by a limit mechanism 5 to prevent them from being opened accidentally.

[0056] It should be noted that since the upper door 2 and the lower door 3 are connected by the linkage 4, locking the upper door 2 and the lower door 3 only requires controlling one of them. To avoid accidental activation, the limiting mechanism 5 is located on the upper side of the door structure.

[0057] Specifically, the limiting mechanism 5 includes: a first detection unit 51, used to detect the position of the upper door body 2 on the door frame 1; a locking member 52, disposed on the door frame 1, used to lock or unlock the upper door body 2; and a control unit 53, used to receive the signal detected by the first detection unit 51 and control the state of the locking member 52.

[0058] Specifically, after the first detection unit 51 detects that the upper door 2 has moved to the designated position when closed, the control unit 53 controls the locking member 52 to lock the upper door 2 onto the door frame 1.

[0059] In order to enable automatic locking and unlocking of the upper door 2 and the lower door 3, a first detection unit 51 is provided. When the first detection unit 51 detects that the upper door 2 is in the closed position, it sends a signal to the control unit 53. Then the control unit 53 controls the locking part to lock the upper door 2 onto the door frame 1.

[0060] Specifically, the first detection unit 51 is a limit switch located on the side of the door frame 1, and the upper door body 2 has a first limiting hole 22 for the rod of the limit switch to be inserted into it; the locking member 52 is an electromagnetic lock located on the side of the door frame 1, and the upper door body 2 has a second limiting hole 23 for the rod of the electromagnetic lock to be inserted into it. When the upper door body 2 gradually moves downward until it is closed, during this process, the rod of the limit switch slides at the side end of the upper door body 2 until it is inserted into the first limiting hole 22. At this time, the limit switch is energized, and the control unit 53 controls the electromagnetic lock to start, so that its rod extends out and is inserted into the second limiting hole 23 of the upper door body 2, thereby completing the locking of the upper door body 2.

[0061] In this embodiment, the optimized limiting mechanism 5 further includes: a second detection unit 54, electrically connected to the control unit 53, used to detect the position of the upper door 2 on the door frame 1;

[0062] The second detection unit 54 includes: a magnetic module 541, disposed on the upper door body 2; and a magnetic field sensing module 542, disposed on the door frame 1.

[0063] In this configuration, after the upper door 2 moves to the designated closed position, the magnetic module 541 is positioned directly opposite the magnetic field sensing module 542. The magnetic field sensing module 542 senses a signal and sends it to the control unit 53.

[0064] Specifically, after the first detection unit 51 and the second detection unit 54 simultaneously detect that the upper door body 2 has moved to the designated position when closed, the control unit 53 controls the locking member 52 to lock the upper door body 2 onto the door frame 1.

[0065] To prevent false alarms from the limit switch, the control unit 53 activates the electromagnetic lock when the upper door 2 is not closed. A second detection unit 54, a magnetic sensor, is also provided. A top crossbeam 14 is located on the upper inner side of the door frame 1, and a magnetic field sensing module 542 is mounted on the top crossbeam 14. A magnetic module 541 is mounted above the upper door 2. When the upper door 2 is closed, the magnetic field sensing module 542 senses the magnetic module 541 and sends a signal to the control unit 53. Only when both the limit switch and the second detection unit 54 detect the signal will the control unit 53 activate the electromagnetic lock, locking the upper door 2. This effectively prevents the electromagnetic lock from activating when the upper door 2 is not closed.

[0066] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
