Description

Technical Field

[0001] This application relates to the field of building construction technology, and more particularly to a suspended construction elevator safety door. Background Technology

[0002] In the construction industry, construction elevators are a common tool for the vertical transportation of personnel and materials during construction. Conventional construction elevator safety doors are usually fixed to the main structure of the building that has been poured, and each elevator entrance on each floor needs to be protected by a safety door. Conventional construction elevator safety doors are only suitable for buildings that are constructed by floor.

[0003] For example, patent CN210236831U discloses a construction elevator safety door, including door edge guardrails fixed to the structural slab of the construction floor, and a first safety door disposed between the door edge guardrails. The first safety door includes a first safety door frame and a safety door leaf installed within the first safety door frame. The first safety door frame includes two columns fixed to the structural slab of the construction floor and a first horizontal bar connecting the upper ends of the two first columns. While the construction elevator safety door disclosed in the above patent is fixed to the structural slab of the construction floor, for structures with a fast pace such as climbing scaffolding, slipform construction, and building construction machines that ascend along with the main building structure, the safety issue of the edge being suspended in mid-air during ascent arises because the main building structure of the construction floor has not yet been completed. Furthermore, since a safety door needs to be installed on each floor, there is a need for repeated installation of safety doors, which has certain limitations in practical use. Summary of the Invention

[0004] This application provides a suspended construction elevator safety door to solve the problems existing in related technologies. The technical solution is as follows:

[0005] A suspended construction elevator safety door includes a suspension fixing component, a connecting component, a suspension assembly, and a safety door. The connecting component is movably connected to the suspension fixing component. The suspension assembly includes a suspension upright and a suspension crossbar. The suspension upright is movably connected to the connecting component, and the suspension crossbar is movably connected to the suspension upright. A first fixing component is provided on the suspension crossbar, and a second fixing component is provided on the safety door. The safety door is movably connected to the suspension crossbar through the first fixing component and the second fixing component.

[0006] In one embodiment, the connecting assembly includes a connecting rod and two clamps, the two clamps being fixed to the left and right sides of the top of the connecting rod, respectively, and the two clamps being arranged opposite to each other.

[0007] In one embodiment, the top of the clamping plate has an inverted T-shaped groove, and clamping blocks are fixed at opposite ends of the top of the clamping plate. One end of the clamping block is fixedly connected to the clamping plate, and the other end of the clamping block extends obliquely upward toward the middle of the clamping plate. The two clamping blocks and the clamping plate form an inverted T-shaped groove. The suspension fastener is an I-beam, and the clamping plate is clamped and fixed to the suspension fastener through the inverted T-shaped groove.

[0008] In one embodiment, the bottom of the connecting rod has a mounting groove recessed from the bottom to the top of the connecting rod, and the top of the suspension pole has a tapered head that matches the mounting groove and is installed in the mounting groove.

[0009] In one embodiment, the connecting rod is provided with a first connecting hole, and the conical head is provided with a second connecting hole. The conical head is movably connected to the connecting rod through the first connecting hole and the second connecting hole.

[0010] In one embodiment, the connecting assembly further includes two connecting plates, which are respectively placed on the left and right sides of the connecting rod and the suspension pole. The connecting plates have multiple third connecting holes, and the connecting plates are movably connected to the connecting rod and the conical head through the first connecting hole, the second connecting hole and the third connecting hole. The suspension pole has a fourth connecting hole, and the connecting plates are movably connected to the suspension pole through the third connecting hole and the fourth connecting hole.

[0011] In one embodiment, there are two connecting components, two hanging uprights, and two hanging crossbars. The two connecting components are movably connected to both ends of the hanging fixing member, the two hanging uprights are movably connected to the two connecting components, and the two ends of the two hanging crossbars are movably connected to the two hanging uprights. The protective door is located between the two hanging uprights and the two hanging crossbars.

[0012] In one embodiment, mounting plates are fixed to both ends of the suspension crossbar, and mounting holes are provided on the mounting plates to pass through the mounting plates on the left and right. The mounting plates are movably connected to the suspension upright through the mounting holes and the fourth connecting hole.

[0013] In one embodiment, the first fixing member includes a first fixing block with a first fixing hole, and the second fixing member includes a second fixing block with a second fixing hole. The protective door is movably connected to the suspension crossbar through the first fixing hole and the second fixing hole.

[0014] In one embodiment, the protective door includes a door frame and two door leaves that open left and right respectively. The two door leaves are movably hinged to the two sides of the door frame, and a second fixing block is fixed to the upper and lower sides of the door frame.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following:

[0016] The construction elevator safety door of this application includes a suspension fixing component, a connecting component, a suspension component, and a safety door. When applied to a building construction machine, the safety door is fixed to the bottom of the steel platform of the machine via the suspension fixing component. The safety door is connected and fixed to the suspension fixing component via the connecting component and the suspension component, thus securing the safety door to the bottom of the steel platform. Since the safety door is fixed to the bottom of the steel platform, it can climb along with the climbing structure of the machine, reaching the elevator entrance on the construction floor. The safety door then provides protection at the elevator entrance. Because the safety door can climb with the climbing structure, it avoids the safety issue of the elevator being suspended near the edge during climbing. Furthermore, since the safety door can climb to the construction floor for protection during each construction phase, it avoids the need for repeated installation of the safety door.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0030] like Figure 1 As shown in the figure, this embodiment discloses a suspended construction elevator safety door, including a suspension fixing component 1, a connecting component 2, a suspension component 3, and a safety door 4. The connecting component 2 is movably connected to the suspension fixing component 1, the suspension component 3 is movably connected to the connecting component 2, and the safety door 4 is movably connected to the suspension component 3.

[0031] like Figure 2 , Figure 3 As shown, to achieve the movable connection between the connecting assembly 2 and the suspension fixing member 1, the connecting assembly 2 includes a connecting rod 21 and two clamping plates 22. The two clamping plates 22 are respectively fixed to the top two sides of the connecting rod 21, and the two clamping plates 22 are arranged opposite to each other on the left and right sides of the connecting rod 21. The top of the clamping plate 22 has an inverted T-shaped groove 23, and clamping blocks 24 are respectively fixed at the opposite ends of the top of the clamping plate 22. One end of the clamping block 24 is fixedly connected to the clamping plate 22, and the other end of the clamping block 24 extends obliquely upward towards the middle of the clamping plate 22. The two clamping blocks 24 and the clamping plate 22 form an inverted T-shaped groove 23.

[0032] The suspension fastener 1 is an I-beam, and the clamping plate 22 is clamped and fixed to the suspension fastener 1 through the inverted T-slot 23. When the clamping plate 22 is clamped and fixed to the suspension fastener 1, the inverted T-slot 23 on the clamping plate 22 is inserted into the lower end of the I-beam, so that the lower end of the I-beam is placed in the inverted T-slot 23, thereby suspending the connecting rod 21 on the suspension fastener 1.

[0033] Preferably, in this embodiment, there are two connecting components 2, which are movably connected to both ends of the suspension fixing member 1. The suspension component 3 includes two suspension uprights 31 and two suspension crossbars 32. The tops of the two suspension uprights 31 are movably connected to the two connecting components 2, and the two ends of the two suspension crossbars 32 are movably connected to the two suspension uprights 31. The protective door 4 is located between the two suspension uprights 31 and the two suspension crossbars 32.

[0034] like Figures 2 to 4 As shown, to achieve the movable connection between the suspension pole 31 and the connecting assembly 2, the bottom of the connecting rod 21 has a mounting groove 25 recessed from the bottom to the top of the connecting rod 21, and the top of the suspension pole 31 has a tapered head 310 that matches the mounting groove 25 and is installed within the mounting groove 25. Preferably, the tapered head 310 is positioned in the middle of the suspension pole 31, and after the tapered head 310 is installed in the mounting groove 25, the top of the suspension pole 31 is in contact with the bottom of the connecting rod 21.

[0035] To further achieve a fixed connection between the conical head 310 and the connecting rod 21, a first connecting hole 210 is provided on the connecting rod 21, and a second connecting hole 311 is provided on the conical head 310. The conical head 310 is movably connected to the connecting rod 21 through the first connecting hole 210 and the second connecting hole 311. Preferably, there can be two or more first connecting holes 210 and second connecting holes 311, with the two or more first connecting holes 210 spaced apart along the height direction of the connecting rod 21. After the conical head 310 is installed in the mounting groove 25, it can be fixed by passing bolts through the second connecting hole 311 and the first connecting hole 210 and then securing it with nuts.

[0036] like Figure 5 As shown, to further strengthen the connection between the connecting rod 21 and the suspension pole 31, the connecting assembly 2 also includes two connecting plates 26. The two connecting plates 26 are respectively placed on both sides of the connecting rod 21 and the suspension pole 31. The connecting plates 26 are movably connected to the connecting rod 21 and the suspension pole 31. To achieve this movable connection, the connecting plates 26 have multiple third connecting holes 261, which are spaced apart along the height direction of the connecting plates 26. The connecting plates 26 are movably connected to the connecting rod 21 and the conical head 310 through the first connecting hole 210, the second connecting hole 311, and the third connecting hole 261. This connection is achieved by passing bolts through the third connecting hole 261, the second connecting hole 311, and the first connecting hole 210, and then securing them with nuts.

[0037] The suspension pole 31 has a fourth connecting hole 312, and the connecting plate 26 is movably connected to the suspension pole 31 through the third connecting hole 261 and the fourth connecting hole 312. When connecting the suspension pole 31 and the connecting plate 26, bolts are passed through the fourth connecting hole 312 and the third connecting hole 261 and then fixed with nuts.

[0038] In this embodiment, the connecting rod 21, connecting plate 26, suspension pole 31 and conical head 310 are all connected and fixed by connecting holes and bolts. The connection method is simple and convenient, the fixing is firm, and it is easy to disassemble, thus facilitating the reuse of the construction elevator safety door.

[0039] like Figure 6 , Figure 7 As shown, to connect and fix the suspension crossbar 32 and the suspension upright 31, mounting plates 321 are fixed at both ends of the suspension crossbar 32. The mounting plates 321 have mounting holes 322 that penetrate the plate from both sides. The mounting plates 321 are movably connected to the suspension upright 31 through the mounting holes 322 and the fourth connecting hole 312. When installing the suspension crossbar 32 and the suspension upright 31, first align the positions of the mounting holes 322 and the fourth connecting hole 312, then pass the bolts through the third connecting hole 261 and the mounting holes 322 in sequence, and finally secure them with nuts.

[0040] To achieve a movable connection between the protective door 4 and the suspension crossbar 32, a first fixing member 323 is provided on the suspension crossbar 32, and a second fixing member 41 is provided on the protective door 4. The protective door 4 is movably connected to the suspension crossbar 32 through the first fixing member 323 and the second fixing member 41. Further, the first fixing member 323 includes a first fixing block 3230, on which a first fixing hole 3231 is formed. The second fixing member 41 includes a second fixing block 410, on which a second fixing hole 411 is formed. The protective door 4 is movably connected to the suspension crossbar 32 through the first fixing hole 3231 and the second fixing hole 411.

[0041] Preferably, there are multiple first fixing members 323 and multiple second fixing members 41. The multiple second fixing members 41 are placed on both sides and the middle of the protective door 4. The multiple first fixing members 323 and multiple second fixing members 41 fix the protective door 4 at different positions, making the protective door 4 more secure. When the protective door 4 is connected to the suspension crossbar 32, the positions of the multiple first fixing holes 3231 and the multiple second fixing holes 411 are aligned, and then bolts are used to fix it in the first fixing holes 3231 and the second fixing holes 411.

[0042] The protective door 4 includes a door frame 42 and two door leaves 43 that open left and right respectively. The two door leaves 43 are movably hinged to the two sides of the door frame 42. The second fixing block 410 is fixed to the upper and lower sides of the door frame 42. The upper and lower sides of the door frame 42 are connected and fixed to the two hanging crossbars 32, making the protective door 4 more secure.

[0043] like Figure 8 As shown, the installation of the suspended construction elevator safety door 4 on the building construction machine will be explained below as an example:

[0044] First, the I-beam is fixed to the bottom of the steel platform 5 of the building construction machine. The I-beam is secured to the steel platform 5 using pipe clamps and bolts commonly available on the market, and then further secured using spot welding. This method of fixing the I-beam to the steel platform 5 facilitates the disassembly and reassembly of the elevator safety door 4, thus enabling its reuse. In other embodiments, the I-beam and steel platform 5 can also be directly fixed together by welding.

[0045] Then, the inverted T-slot 23 on the clamping plate 22 is inserted into the lower end of the I-beam, suspending the connecting rod 21 on the I-beam. Next, the conical head 310 is inserted into the mounting slot 25, and the two connecting plates 26 are placed on the left and right sides of the connecting rod 21. Then, the connecting plates 26, connecting rod 21, conical head 310 and suspension pole 31 are connected and fixed by bolts.

[0046] Next, place the two suspension crossbars 32 between the two suspension uprights 31, and connect and fix the two suspension crossbars 32 to the two suspension uprights 31 with bolts. Finally, place the door frame 42 between the two suspension crossbars 32, and fit the first fixing block 3230 and the second fixing block 410 together. Then, connect and fix the first fixing block 3230 and the second fixing block 410 with bolts to complete the installation of the elevator safety door.

[0047] In this embodiment, the elevator safety door is fixed to the bottom of the steel platform 5 of the building construction machine using a suspension fastener 1. The safety door 4 is connected and fixed to the suspension fastener 1 via a connecting component 2 and a suspension component 3, thus securing the safety door 4 to the bottom of the steel platform 5. Since the safety door 4 is fixed to the bottom of the steel platform 5, it can climb along with the climbing structure of the building construction machine, reaching the elevator entrance on the construction floor. The safety door 4 then provides protection at the elevator entrance. Because the safety door 4 can climb with the climbing structure, it avoids the safety issue of the elevator being suspended near the edge during climbing. Furthermore, since the safety door 4 can climb to the construction floor for protection during each construction phase, it avoids the need for repeated installation of the safety door 4.
