Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a linkage folding door for elevators. Background Art
[0002] In construction projects, elevators are used for vertical transportation of personnel and materials and are often installed on the outside of building structures. In order to ensure that the elevator does not collide with the building structure during lifting, sufficient space must be reserved between the elevator and the building structure. The protective doors of some elevators are opened by pulling them in the vertical plane, that is, pulling them up and down or horizontally. When personnel and materials pass through the gap between the elevator and the building structure, there is a certain risk of falling, which affects construction safety.
[0003] In order to solve the risk of falling due to the gap between the elevator and the building structure, in the prior art, a passage is often built between the elevator and the building structure to reduce the width of the gap, which not only consumes materials and man-hours, but also easily collides with the elevator if there is an error in the location of the passage, which poses certain safety hazards, and the passage also cannot completely close the gap between the elevator and the building structure. Therefore, it is necessary to provide a linkage folding door for an elevator that can solve the problem in the prior art that people and materials are prone to falling when passing through the gap between the elevator and the building structure. Summary of the invention
[0004] The utility model aims to provide a linkage folding door for an elevator, which can solve the problem in the prior art that people and materials are prone to fall when passing through the gap between the elevator and the building structure.
[0005] The utility model is achieved in this way:
[0006] A linkage folding door for an elevator comprises a protective door, an external door, a linkage cable and a cable-threading member; the protective door is installed in an up-and-down pull-out manner at the opening of the elevator facing the building structure, and one end of the external door is rotatably connected to the bottom of the opening of the elevator; a pair of cable-threading members are respectively arranged on both sides of the opening of the elevator, one end of a pair of linkage cables is respectively connected to both sides of the bottom of the protective door, and the other ends of the pair of linkage cables are respectively connected to both sides of the other end of the external door after passing through a pair of cable-threading members, so that the external door can be erected above the gap between the elevator and the building structure, or the other end of the external door can cover the outside of the protective door.
[0007] The inner walls on both sides of the opening of the elevator are respectively provided with vertical guide rails, so that the edges on both sides of the protective door can be slidably inserted into the vertical guide rails to form an up and down pull-out protective door.
[0008] When the protective door descends and closes the opening of the elevator, the external door is attached to the outer wall of the protective door and is located outside the building structure.
[0009] When the protective door rises and opens the opening of the elevator, the external door is horizontally erected between the opening bottom of the elevator and the floor of the building structure.
[0010] The length of the protective door is consistent with the opening length of the elevator, and the width of the protective door is greater than the width of the gap between the elevator and the building structure.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The utility model is provided with a protective door, an external door and a linkage cable. When the protective door is opened upward, the linkage cable releases the external door to make it flip downward and completely cover the gap between the elevator and the building structure, thereby realizing the function of a temporary passage, thereby avoiding the risk of falling when people and materials enter and exit the elevator. At the same time, when the protective door is closed downward, the linkage cable pulls the external door to make it flip upward and fit on the outer wall of the protective door, thereby ensuring the safety of the elevator's lifting and lowering operation.
[0013] 2. The utility model is provided with a linkage cable and a cable-threading member, the linkage cable is connected between the protective door and the external door, the cable-threading member is installed on the elevator for movably threading the linkage cable, thereby realizing the switching linkage and synchronization of the protective door and the external door through the linkage cable, which does not affect the normal use of the elevator, and does not need to separately install electrical equipment for controlling the external door, which is energy-saving and environmentally friendly.
[0014] 3. The utility model has a simple structure and can be used on most of the lifts with pull-up and pull-out doors in the prior art. It is easy to obtain materials and install, has low cost, and does not require a passage between the lift and the building structure, thus effectively ensuring the safety of the lift operation.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Please see attached Figure 1 and attached Figure 2 A linkage folding door for an elevator comprises a protective door 1, an external door 2, a linkage cable 3 and a cable-threading member 4; the protective door 1 is installed in an up-and-down pull-out manner at the opening of the elevator 5 facing the building structure, and one end of the external door 2 is rotatably connected to the bottom of the opening of the elevator 5; a pair of cable-threading members 4 are respectively arranged on both sides of the opening of the elevator 5, one end of a pair of linkage cables 3 is respectively connected to both sides of the bottom of the protective door 1, and the other ends of the pair of linkage cables 3 are respectively connected to both sides of the other end of the external door 2 after passing through a pair of cable-threading members 4, so that the external door 2 can be erected above the gap between the elevator 5 and the building structure, or the other end of the external door 2 can cover the outside of the protective door 1.
[0022] The elevator 5 is a building lifting equipment in the prior art. The protective door 1 adopts an elevator door that can be pulled up and down, and the lifting and opening and closing of the protective door 1 are controlled by conventional methods such as motors in the prior art. The working process and working principle of the elevator 5 and its protective door 1 will not be repeated here.
[0023] When the lift 5 is suspended on a certain floor of the building structure, the external door 2 is set up above the gap between the lift 5 and the building structure and used as a temporary passage. Figure 3 As shown, the gap is blocked to prevent falling accidents of people and materials; during the lifting and lowering operation of the elevator 5, the external door 2 is attached to the outer wall of the protective door 1 and rises and falls synchronously with the elevator 5. Since there is enough gap between the elevator 5 and the outside of the building structure, the external door 2 can be prevented from colliding with the building structure, and it is safe to use.
[0024] The linkage cable 3 controls the protective door 1 and the external door 2 in a linkage manner, so that the protective door 1 opens upwards while the external door 2 is synchronously turned outward and opened and horizontally erected on the gap between the elevator 5 and the building structure, and the protective door 1 closes downwards while the external door 2 is synchronously turned inward and attached to the outside of the protective door 1. The protective door 1 moves vertically and the external door 2 turns over, and the linkage control is achieved through the linkage cable 3, without interfering with each other, and the safety of the switch operation can be ensured, and there is no need to set up additional control equipment such as motors to synchronously control the external door 2, which is convenient to operate, simple in structure, and energy-saving and environmentally friendly.
[0025] Please see attached Figure 4 The inner walls on both sides of the opening of the lift 5 are respectively provided with vertical guide rails 501, so that the edges on both sides of the protective door 1 can be slidably inserted into the vertical guide rails 501 to form an up and down pull-out protective door.
[0026] The vertical guide rail 501 is used to guide the protective door 1 to be pulled up and down. Preferably, sliding blocks can be provided on both sides of the protective door 1 to cooperate with the vertical guide rail 501 to improve the stability and safety of the protective door 1 when being pulled up and down.
[0027] When the protective door 1 descends and closes the opening of the elevator 5, the external door 2 is attached to the outer wall of the protective door 1 and is located outside the building structure.
[0028] Since the protective door 1 is arranged on the inner side of the opening of the elevator 5 through the vertical guide rail 501, the protruding thickness of the external door 2 can be minimized when the external door 2 is attached to the outer wall of the protective door 1, thereby preventing the external door 2 from colliding with the building structure when being lifted or lowered in the gap.
[0029] When the protective door 1 rises and opens the opening of the elevator 5, the external door 2 is horizontally erected between the opening bottom of the elevator 5 and the floor 6 of the building structure.
[0030] The external door 2 is horizontally erected between the elevator 5 and the building structure, and can cover the gap between the elevator 5 and the building structure, thereby improving the safety of personnel and materials entering and exiting the elevator 5 and effectively preventing the risk of falling. A patterned steel plate or the like can be selected as the external door 2 according to the load requirements to meet the load-bearing safety when personnel and materials enter and exit.
[0031] Preferably, a steel wire rope of appropriate length can be selected as the linkage cable 3 according to the movement stroke of the protective door 1 and the external door 2, and a steel ring can be welded as a rope threading member 4 at a suitable height on the outer walls on both sides of the opening of the elevator 5 to meet the linkage movement requirements of the protective door 1 and the external door 2, and to avoid interference with the movement of the protective door 1 caused by the setting of the linkage cable 3.
[0032] The length of the protective door 1 is consistent with the opening length of the elevator 5, and the width of the protective door 1 is slightly larger than the width of the gap between the elevator 5 and the building structure, thereby ensuring effective coverage of the gap between the elevator 5 and the building structure.
[0033] Please see attached Figure 1 To Attachment Figure 4 , the method of using the utility model is:
[0034] Grooves are provided on the inner walls on both sides of the opening of the lift 5 and vertical guide rails 501 are installed for the upward and downward pulling installation of the protective door 1. The protective door 1 can be controlled by conventional means such as a motor to move up and down to achieve opening and closing, which will not be described in detail here.
[0035] According to the width of the gap between the elevator 5 and the building structure and the opening length of the elevator 5, an external door 2 with a width slightly larger than the gap width and a length consistent with the length of the elevator 5 is selected, and one end of the external door 2 is installed to the bottom of the opening of the elevator 5 through a rotating hinge.
[0036] According to the rotation stroke of the other end of the external door 2 and the up and down pulling stroke of the protective door 1, select the linkage cable 3 and the cable insertion piece 4 of appropriate length, and install the cable insertion piece 4 on both sides of the opening of the elevator 5 by welding, screwing, etc., one end of the linkage cable 3 is fixed to the bottom of the protective door 1, and the other end of the linkage cable 3 is fixed to the other end of the external door 2, and the linkage cable 3 movably passes through the cable insertion piece 4.
[0037] A pair of linkage cables 3 are symmetrically arranged between the protective door 1 and the external door 2, thereby ensuring the linkage opening and closing stability and force uniformity of the protective door 1 and the external door 2. The pair of linkage cables 3 move synchronously, and the movement process of one of the linkage cables 3 is described in detail below:
[0038] When the elevator 5 is lifted to the designated floor, the bottom of the elevator 5 is located at the height of the floor 6 of the floor. When the protective door 1 is pulled upward to open, one end of the linkage cable 3 rises synchronously with the protective door 1. Under the gravity of the external door 2, the external door 2 is flipped outward through the rotating shaft hinge to open, and the linkage cable 3 moves in the cable threading member 4.
[0039] The external door 2 flips outward to horizontally overlap the floor 6 of the building structure and then stops moving, thereby covering the gap between the elevator 5 and the building structure as a temporary passage. At this time, the protective door 1 moves to the highest position, fully opening the opening of the elevator 5 to facilitate the entry and exit of personnel and materials, and no falling accidents will occur due to the existence of the gap when entering and exiting.
[0040] When the lift 5 needs to be lifted, the protective door 1 moves downward, and drives one end of the linkage cable 3 to move downward synchronously, and the other end of the linkage cable 3 passes through the cable-threading member 4 and pulls the other end of the external door 2, so that the external door 2 turns upward around the hinge. Until the protective door 1 moves to the lowest position, the external door 2 is attached to the outer wall of the protective door 1, and the door is closed, and the lift 5 starts to run.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
