Description

Technical Field

[0001] This utility model relates to the field of protective door technology, and in particular to an upward-opening elevator shaft protective door device. Background Technology

[0002] During the construction phase of a building project, elevator shafts, as a major hazard source connecting all floors, require strict edge protection at their openings, making on-site safety management paramount. Traditional elevator shaft safety doors often employ fixed fence doors or simple swing doors, which have numerous drawbacks.

[0003] For example, the inability to open fixed protective doors severely hinders vertical transportation operations and the hoisting of large materials within the shaft. If these doors are temporarily removed for construction convenience, the opening will remain exposed without protection for an extended period, greatly increasing the risk of personnel or materials falling.

[0004] While common swing-type protective doors can be opened, they occupy passage space outwards, which can easily hinder the passage of personnel, equipment and materials in narrow construction environments. Furthermore, their hinge structure is easily damaged by collisions, causing the protective door to fail. Utility Model Content

[0005] In view of this, the present invention provides an upward-opening elevator shaft protection door device, the main purpose of which is to improve the reliability and convenience of elevator shaft protection.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0007] This utility model provides a lift-opening elevator shaft safety door device, which includes: two suspension components and a door panel;

[0008] The two suspension components are respectively fixedly installed on the wall on opposite sides of the shaft opening. Each suspension component is provided with a guide groove. The upper end of the guide groove is connected to the groove. The opening of the groove faces upward. The middle section of the guide groove is bent away from the wall. The lower ends of the groove and the guide groove are located in the same vertical plane.

[0009] The upper opposite sides of the door panel are fixedly connected to the limiting posts, the limiting posts are slidably connected to the guide groove and the groove, and the lower side of the door panel is provided with a locking mechanism, the locking mechanism is provided with a pin, and the pin corresponds to the pin hole in the ground.

[0010] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0011] Optionally, the guide groove is arc-shaped.

[0012] Optionally, the guide groove is V-shaped.

[0013] Optionally, it may also include two handles, which are fixedly connected to opposite sides of the door panel.

[0014] Optionally, the door panel includes a door frame and a wire mesh fixedly connected to the inner edge of the door frame.

[0015] Optionally, the suspension component includes a first plate and a second plate that are perpendicular to each other. The first plate is bolted to the wall at the edge of the well opening, and the guide groove and the recess are located on the second plate.

[0016] Optionally, the locking mechanism further includes an ear plate and two guide tubes. The two guide tubes are coaxially and vertically installed on the lower side of the door panel. The pin passes through the two guide tubes in sequence, and one end of the ear plate is fixedly connected to the pin between the two guide tubes.

[0017] By employing the above technical solution, this utility model has at least the following advantages:

[0018] During daily operation, if personnel do not need to enter the elevator shaft, the limit post is located at the lower end of the guide groove. At this time, the door panel is in the first position, and the gap between the door panel and the wall can be set to a smaller value (when processing the suspension components, the lower end of the guide groove is against the wall, and the door panel hangs down naturally, which can achieve the smaller value of the gap). The locking mechanism's pin is inserted into the ground pin hole, and the door panel cannot be lifted upward with the limit post as the axis. The door panel can provide reliable protection.

[0019] In daily work, if personnel need to enter the elevator shaft, first pull the pin out of the ground pin hole and lift the door panel upwards, so that the limiting post on the upper side of the door panel moves into the groove. At this time, the door panel is in the second position, so that the pin of the locking mechanism is disengaged from the ground pin hole and the pin can no longer be inserted into the ground pin hole. At this time, the door panel can be lifted upwards with the limiting post as the axis, so that a gap is created between the door panel and the wall, making it easier for personnel to enter and exit the elevator shaft and improving convenience.

[0020] Because the lower ends of the groove and the guide groove are located on the same vertical plane, the gap between the door panel in the first position and the wall is equal to the gap between the door panel in the second position and the wall. In this way, the gap between the door panel in the second position and the wall is also a smaller value. Thus, when the door panel in the second position is not lifted, the door panel can also form a seal on the elevator shaft opening, preventing people from falling accidentally and improving reliability.

[0028] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 3 As shown, an embodiment of the present invention provides an upward-opening elevator shaft protective door device, which includes: two suspension components 1 and a door panel 2;

[0031] The two suspension components 1 are respectively fixedly installed on the wall on opposite sides of the well opening. Each suspension component 1 is provided with a guide groove 4. The upper end of the guide groove 4 is connected to the groove 5. The opening of the groove 5 faces upward. The middle section of the guide groove 4 is bent away from the wall. The lower ends of the groove 5 and the guide groove 4 are located in the same vertical plane.

[0032] The upper opposite sides of the door panel 2 are fixedly connected to the limiting post 6, the limiting post 6 is slidably connected to the guide groove 4 and the groove 5, and the lower side of the door panel 2 is provided with a locking mechanism, the locking mechanism is provided with a pin 7, the pin 7 corresponds to the ground pin hole 8.

[0033] The working process of a lift-opening elevator shaft safety door device is as follows:

[0034] During daily work, if personnel do not need to enter the elevator shaft, the limit post 6 is located at the lower end of the guide groove 4. At this time, the door panel 2 is in the first position, and the gap between the door panel 2 and the wall can be set to a smaller value (when processing the suspension component 1, the lower end of the guide groove 4 is against the wall, and the door panel 2 hangs down naturally, which can achieve the smaller value of the gap). The locking mechanism's pin 7 is inserted into the ground pin hole 8, and the door panel 2 cannot be lifted upward with the limit post 6 as the axis. The door panel 2 can provide reliable protection.

[0035] In daily work, if personnel need to enter the elevator shaft, first pull the pin 7 out of the ground pin hole 8 and lift the door panel 2 upwards, so that the limiting post 6 on the upper side of the door panel 2 moves into the groove 5. At this time, the door panel 2 is in the second position, so that the pin 7 of the locking mechanism is disengaged from the ground pin hole 8 and the pin 7 can no longer be inserted into the ground pin hole 8. At this time, the door panel 2 can be lifted upwards with the limiting post 6 as the axis, so that a gap is created between the door panel 2 and the wall, making it easier for personnel to enter and exit the elevator shaft.

[0036] Because the lower ends of the groove 5 and the guide groove 4 are located on the same vertical plane, the gap between the door panel 2 in the first position and the wall is equal to the gap between the door panel 2 in the second position and the wall. Thus, the gap between the door panel 2 in the second position and the wall is also a smaller value. Therefore, when the door panel 2 in the second position is not lifted, the door panel 2 can also form a seal on the elevator shaft opening to prevent people from falling accidentally.

[0037] Specifically, the plane containing guide groove 4 and groove 5 is perpendicular to the wall surface.

[0038] like Figure 3 As shown in the specific embodiment, the guide groove 4 is arc-shaped.

[0039] In this embodiment, specifically, the guide groove 4 is arc-shaped, and the inner edge of the guide groove 4 is relatively smooth. The limiting post 6 slides in the guide groove 4 with little resistance.

[0040] like Figure 2 and Figure 4 As shown, in a specific embodiment, the guide groove 4 is V-shaped.

[0041] In this embodiment, specifically, the guide groove 4 is in the shape of a reclining V, and the included angle of the V shape of the guide groove 4 is 120°, which makes it more convenient for the door panel 2 to change between the first position and the second position.

[0042] like Figures 1 to 3 As shown, in a specific embodiment, it also includes two handles 9, which are respectively fixedly connected to opposite sides of the door panel 2.

[0043] In this embodiment, specifically, when people need to enter the elevator shaft, they can hold the handle 9 and lift the door panel 2 upwards for easy operation.

[0044] like Figure 1 As shown, in a specific embodiment, the door panel 2 includes a door frame 201 and a wire mesh 202 fixedly connected to the inner edge of the door frame 201.

[0045] In this embodiment, the wire mesh 202 is a hollow mesh, which reduces the overall weight of the door panel 2 and also makes it easier for people to observe the situation inside the elevator shaft before lifting the door panel 2 to confirm whether it is safe.

[0046] like Figure 4 and Figure 5 As shown, in a specific embodiment, the suspension component 1 includes a first plate surface 101 and a second plate surface 102 that are perpendicular to each other. The first plate surface 101 is bolted to the wall surface at the edge of the well opening, and the guide groove 4 and the groove 5 are located on the second plate surface 102.

[0047] In this embodiment, specifically, the first plate 101 and the second plate 102 form an integrally formed triangular iron plate. The first plate 101 is installed on the wall side of the elevator shaft opening by expansion bolts, so that the second plate 102 is perpendicular to the wall, thereby facilitating the sliding of the limiting column 6 in the guide groove 4 and the groove 5.

[0048] like Figure 6 As shown, in a specific embodiment, the locking mechanism further includes an ear plate 10 and two guide tubes 11. The two guide tubes 11 are coaxially and vertically installed on the lower side of the door panel 2. The pin 7 passes through the two guide tubes 11 in sequence, and one end of the ear plate 10 is fixedly connected to the pin 7 between the two guide tubes 11.

[0049] In this embodiment, specifically, the lower side of the door panel 2 is fixedly connected to the perforated plate 12, and the other end of the ear plate 10 is provided with a through hole. The perforated plate 12 is located on the rotation trajectory of the other end of the ear plate 10 and can pass through the through hole.

[0050] When the door panel 2 is in the first position, the bolt 7 is inserted into the ground pin hole 8, and then the ear plate 10 is rotated so that the hole plate 12 passes through the through hole. Then the lock's latch passes through the hole of the hole plate 12 to fix the ear plate 10 and prevent the bolt 7 from coming off the ground pin hole 8.

[0051] When people need to lift the door panel 2 from the first position to the second position, they first hold the ear plate 10, pull the pin 7 out of the ground pin hole 8, and then lift the limit post 6 on the opposite side of the upper end of the door panel 2 into the groove 5.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
