Description

Technical Field

[0001] This application relates to the technical field of elevator sills, and more specifically, to an elevator sill and its preparation process. Background Art

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. Elevators are divided into vertical lift car type and step type. Before the car type is installed and used, an elevator sill needs to be installed in front of the elevator door to assist in the opening and closing of the elevator door.

[0003] After the elevator sill is installed and used, it will be repeatedly stepped on by the people taking the elevator. The force exerted by the passengers when stepping on the sill varies, and the elevator sill will deform under the long-term external force, which will affect the opening and closing of the elevator door due to the deformation of the sill.

[0004] Therefore, an anti-deformation elevator sill is provided to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems, this application provides an elevator sill and its preparation process.

[0006] The elevator sill and its preparation process provided by this application adopt the following technical solutions: An elevator sill includes an elevator sill main body. A T-shaped support block perpendicular to the lower surface of the elevator sill main body is provided, and the vertical end of the T-shaped support block is connected to the lower surface of the elevator sill main body. A side inner groove is formed between the inner walls in the horizontal direction of the elevator sill main body and the T-shaped support block, and a lining mechanism is arranged in the side inner groove; Among them, the lining mechanism includes an upper pressing member, and the upper end of the upper pressing member is connected to the lower surface of the elevator sill main body. A lower pressing member matching the inclined surface at the lower end of the upper pressing member is arranged, and the lower surface of the lower pressing member is connected to the upper surface of the T-shaped support block. A support plug is rotatably connected to one side of the lower pressing member. A chute penetrating the width direction of the support plug is formed on one side of the support plug. A sliding rod is slidably connected in the chute, and both ends of the sliding rod are respectively connected with a support frame. An insertion sleeve is arranged at the inclined end of the support plug, and the upper surface of the insertion sleeve is connected to the lower surface of the elevator sill main body.

[0007] Through the above technical solution: when an external force is encountered during the installation and use of the elevator sill main body, the external force squeezes the lower surface of the elevator sill main body. Then, when the elevator sill main body is subjected to an external force, it can squeeze the upper pressing member, and then the upper pressing member squeezes the lower pressing member. In this way, the pressure on the upper surface of the elevator sill main body can be weakened by the extrusion of the upper pressing member and the lower pressing member, thereby avoiding the deformation of the elevator sill main body caused by external forces, and at the same time avoiding the deformation of the elevator door slide rail, which results in a poor transmission performance of the elevator door sliding in the elevator door slide rail.

[0008] Furthermore, a T-shaped rail groove is provided on one side of the lower surface of the elevator sill main body, and a notch is provided on one side of the elevator sill main body where the T-shaped rail groove is located. The upper surface and the lower surface of the notch are respectively provided with a first slide member and a second slide member.

[0009] Through the above technical solution: when installing the elevator sill main body, the plug-in member is embedded in the side wall of the elevator shaft, and then the plug-in member is connected to the side wall of the elevator shaft by pouring concrete. After the plug-in member is poured, the first slide member and the second slide member at the notch of the elevator sill main body are slidably connected to the first T-shaped slider and the second T-shaped slider on the embedded member, so that the elevator sill main body and the connecting mechanism can be initially connected.

[0010] Furthermore, a connecting mechanism is slidably connected in the inner cavities of the first slide member and the second slide member at the same time. The connecting mechanism includes an embedded member. A second T-shaped slider is provided on one side of the embedded member, and a first T-shaped slider is provided on the upper surface of the embedded member. The first T-shaped slider and the second T-shaped slider are slidably connected to the first slide member and the second slide member.

[0011] Furthermore, a plug-in member is provided on the side of the embedded member opposite to the second T-shaped slider. Barbs are provided on both sides of the plug-in member. An L-shaped guide member is provided on the lower surface of the embedded member, and a threaded hole is provided on the horizontal upper surface of the L-shaped guide member, and a bolt is threadedly connected in the threaded hole.

[0012] Through the above technical solution: after the elevator sill main body and the connecting mechanism can be initially connected, the cap end of the bolt is snapped into the T-shaped rail groove, and at the same time the lower end of the bolt is connected to the threaded hole on the L-shaped guide member. At the same time, a nut is threadedly connected to the end of the bolt. In this way, the elevator sill main body and the connecting mechanism can improve the connection tightness through an embedded connection method, so that the support connection of the elevator sill main body is more firm, and the service life of the elevator sill main body can be enhanced.

[0013] Furthermore, an elevator door slide rail is provided on the upper surface of the elevator sill main body.

[0014] Further, a plurality of the connecting mechanisms are provided, and the plurality of connecting mechanisms are all slidably connected to the first slide member and the second slide member.

[0015] Through the above technical solution: The embedded connection of the connecting mechanism with the elevator sill main body can make the installation of the elevator sill main body more compact, thereby improving the service life of the elevator sill main body.

[0016] Further, a plurality of the lining mechanisms are provided, and the plurality of lining mechanisms are respectively evenly distributed in the side inner groove along the length direction of the elevator sill main body.

[0017] Through the above technical solution: When the elevator sill main body is deformed by an external force, the external force can squeeze the upper pressing member, and then the upper pressing member squeezes the lower pressing member. In this way, the pressure on the upper surface of the elevator sill main body can be weakened by the extrusion of the upper pressing member and the lower pressing member, thereby avoiding the deformation of the elevator sill main body caused by the external force, and at the same time avoiding the deformation of the elevator door slide rail, which leads to poor transmission performance of the elevator door sliding in the elevator door slide rail.

[0018] Further, the cap end of the bolt is slidably connected to the inner cavity of the T-shaped rail groove, and a plurality of bolts are provided.

[0019] Through the above technical solution: The elevator sill main body and the connecting mechanism can be conveniently and fixedly connected through the bolts.

[0020] Further, the inclined end of the support plug is clamped with the inner cavity on one side of the socket.

[0021] Through the above technical solution: After the pressure on the upper surface of the elevator sill main body is weakened by the extrusion of the upper pressing member and the lower pressing member, the lower pressing member is pushed by the upper pressing member, and then the lower pressing member pushes the support plug rotatably connected on one side. Then, the chute opened on the support plug can slide on the slide bar, and then the support plug can be inserted into the socket. The mutual clamping of the support plug and the socket can quickly support the deformed elevator sill main body upward, so that the deformation of the elevator sill main body only occurs locally, which can reduce the deformation amplitude of the elevator sill main body, thereby improving the service life of the elevator sill main body.

[0022] The present invention also discloses a preparation process of an elevator sill, including the following steps: S1: Preparation of materials. First, place the prepared metal plate on the processing milling machine, and mill a rectangular notch on one side of the strip-shaped metal plate through the milling machine, so that the strip-shaped metal plate is initially formed; S2: Welding work. Then place the preliminarily formed strip-shaped metal plate on the welding machine, and then align the prepared T-shaped support block with the notch surface opened on the elevator sill main body. Next, weld the vertical ends of the elevator sill main body and the T-shaped support block through the welding machine. Then, sequentially weld the prepared first slide member and second slide member on the surface of the rectangular notch. At the same time, weld the prepared elevator door slide rail on the upper surface of the elevator sill main body. In this way, the elevator sill made of the strip-shaped metal plate is preliminarily formed; S3: Installation of the lining mechanism structure. Then install the lining mechanism on the left side of the T-shaped support block, and then weld the lower end of the support frame to the horizontal upper surface of the T-shaped support block through the welding machine. At the same time, connect the upper end of the upper pressing member to the upper surface of the inner cavity of the side inner groove, then connect the lower end of the lower pressing member to the lower surface of the inner cavity of the side inner groove, and then weld the upper surface of the insertion sleeve to the upper surface of the inner cavity of the side inner groove. In this way, the processing of the elevator sill is completed.

[0023] In summary, the present application includes at least the following beneficial technical effects: The present invention can avoid the deterioration of the transmission performance of the elevator door slide rail. The pressure received on the upper surface of the elevator sill main body can be weakened by the extrusion of the upper pressing member and the lower pressing member, so as to avoid the deformation of the elevator sill main body caused by external forces. At the same time, it can avoid the deformation of the elevator door slide rail, resulting in the deterioration of the transmission performance of the elevator door sliding in the elevator door slide rail; The present invention can improve the sealing performance of the connection between the elevator sill main body and the connection mechanism. The cap end of the bolt is snapped into the T-shaped rail groove, and at the same time, the lower end of the bolt is connected to the threaded hole on the L-shaped guide member. Then, the nut is threadedly connected to the end of the bolt. In this way, the elevator sill main body and the connection mechanism can improve the connection sealing performance through the embedded connection method; The present invention can improve the service life of the elevator sill main body. The mutual clamping of the support plug-in and the insertion sleeve can enable the deformed elevator sill main body to be quickly supported upward, so that the deformation of the elevator sill main body only occurs locally, which can reduce the deformation amplitude of the elevator sill main body, thereby improving the service life of the elevator sill main body.

[0029] Refer to Figure 1 - Figure 8, an elevator sill, comprising an elevator sill main body 1. A T-shaped support block 10 perpendicular thereto is provided on the lower surface of the elevator sill main body 1, and the vertical end of the T-shaped support block 10 is connected to the lower surface of the elevator sill main body 1. A side inner groove 7 is formed between the inner walls of the elevator sill main body 1 and the T-shaped support block 10 in the horizontal direction, and a lining mechanism 8 is provided in the side inner groove 7; Among them, the lining mechanism 8 includes an upper pressing member 805, and the upper end of the upper pressing member 805 is connected to the lower surface of the elevator sill main body 1. A lower pressing member 806 matching the inclined surface at the lower end of the upper pressing member 805 is provided, and the lower surface of the lower pressing member 806 is connected to the upper surface of the T-shaped support block 10. A support plug-in 801 is rotatably connected to one side of the lower pressing member 806. A chute 802 penetrating the width direction of the support plug-in 801 is provided on one side of the support plug-in 801. A slide bar 804 is slidably connected in the chute 802, and both ends of the slide bar 804 are respectively connected to a support frame 803. An insertion sleeve 9 is provided at the inclined end of the support plug-in 801, and the upper surface of the insertion sleeve 9 is connected to the lower surface of the elevator sill main body 1.

[0030] When an external force is encountered during the use of the elevator sill main body 1, the external force squeezes the lower surface of the elevator sill main body 1. Then, when the elevator sill main body 1 is subjected to the external force, it can squeeze the upper pressing member 805. Then, the upper pressing member 805 squeezes the lower pressing member 806. In this way, the pressure on the upper surface of the elevator sill main body 1 can be weakened by the extrusion of the upper pressing member 805 and the lower pressing member 806, so as to avoid the deformation of the elevator sill main body 1 caused by the external force, and at the same time, avoid the deformation of the elevator door slide rail 3, resulting in poor transmission of the elevator door sliding in the elevator door slide rail 3.

[0031] Refer to Figure 1 , a T-shaped rail groove 4 is provided on one side of the lower surface of the elevator sill main body 1. A notch is provided on one side of the elevator sill main body 1 where the T-shaped rail groove 4 is located, and a first slide member 5 and a second slide member 6 are respectively provided on the upper surface and the lower surface of the notch.

[0032] When the elevator sill main body 1 needs to be installed, the plug-in plate member 203 is embedded in the side wall of the elevator shaft, and then the plug-in plate member 203 is connected to the side wall of the elevator shaft by pouring concrete. After the plug-in plate member 203 is poured, the first slide member 5 and the second slide member 6 at the notch of the elevator sill main body 1 are slidably connected to the first T-shaped slider 205 and the second T-shaped slider 206 on the embedded part 201, so that the elevator sill main body 1 and the connection mechanism 2 can be preliminarily connected.

[0033] Refer to Figure 3, a connecting mechanism 2 is slidably connected in the inner cavities of the first slide member 5 and the second slide member 6 at the same time. The connecting mechanism 2 includes an embedded part 201. A second T-shaped slider 206 is arranged on one side of the embedded part 201, and a first T-shaped slider 205 is arranged on the upper surface of the embedded part 201. The first T-shaped slider 205 and the second T-shaped slider 206 are slidably connected to the first slide member 5 and the second slide member 6.

[0034] Referring to Figure 3 , on the side of the embedded part 201 opposite to the second T-shaped slider 206, there is a plug-in plate member 203. Barbs 204 are arranged on both sides of the plug-in plate member 203. An L-shaped guide member 207 is arranged on the lower surface of the embedded part 201, and a threaded hole 202 is opened on the horizontal upper surface of the L-shaped guide member 207, and a bolt 11 is threadedly connected in the threaded hole 202.

[0035] After the elevator sill main body 1 and the connecting mechanism 2 can be initially connected, the cap end of the bolt 11 is snapped into the T-shaped rail groove 4, and at the same time, the lower end of the bolt 11 is connected to the threaded hole 202 on the L-shaped guide member 207. At the same time, a nut is threadedly connected to the end of the bolt 11. In this way, the elevator sill main body 1 and the connecting mechanism 2 can improve the connection tightness through the embedded connection method, so that the support connection of the elevator sill main body 1 is more firm, and the service life of the elevator sill main body 1 can be enhanced.

[0036] Referring to Figure 1 , an elevator door slide rail 3 is arranged on the upper surface of the elevator sill main body 1.

[0037] Referring to Figure 2 , several connecting mechanisms 2 are provided, and several connecting mechanisms 2 are all slidably connected to the first slide member 5 and the second slide member 6.

[0038] The embedded connection of the connecting mechanism 2 and the elevator sill main body 1 can make the installation of the elevator sill main body 1 more compact, and thus the service life of the elevator sill main body 1 can be improved.

[0039] Referring to Figure 7 , several lining mechanisms 8 are provided, and several lining mechanisms 8 are evenly distributed in the side inner groove 7 along the length direction of the elevator sill main body 1 respectively.

[0040] When the elevator sill main body 1 is deformed by an external force, the external force can squeeze the upper pressing member 805, and then the upper pressing member 805 squeezes the lower pressing member 806. In this way, the pressure on the upper surface of the elevator sill main body 1 can be weakened by the extrusion of the upper pressing member 805 and the lower pressing member 806, so as to avoid the deformation of the elevator sill main body 1 caused by the external force, and at the same time, avoid the deformation of the elevator door slide rail 3, resulting in poor transmission of the elevator door sliding in the elevator door slide rail 3.

[0041] Refer to Figure 5 , the cap end of the bolt 11 is slidably connected to the inner cavity of the T-shaped rail groove 4, and a plurality of bolts 11 are provided.

[0042] The elevator sill main body 1 and the connecting mechanism 2 can be conveniently and fixedly connected by the bolt 11.

[0043] Refer to Figure 7 , the inclined end of the support insert 801 is clamped with the inner cavity on one side of the insert sleeve 9.

[0044] When the pressure on the upper surface of the elevator sill main body 1 is weakened by the extrusion of the upper pressing member 805 and the lower pressing member 806, the lower pressing member 806 is pushed by the upper pressing member 805, and then the lower pressing member 806 pushes the support insert 801 rotatably connected to one side. Then, the chute 802 formed on the support insert 801 can slide on the slide bar 804, and then the support insert 801 can be inserted into the insert sleeve 9. The mutual clamping of the support insert 801 and the insert sleeve 9 can quickly support the deformed elevator sill main body 1 upward, so that the deformation of the elevator sill main body 1 only occurs locally, which can reduce the deformation amplitude of the elevator sill main body 1 and thus improve the service life of the elevator sill main body 1.

[0045] The present invention also discloses a preparation process of an elevator sill, including the following steps: S1: Preparation of materials. First, place the prepared metal plate on the processing milling machine, and mill a rectangular notch on one side of the strip-shaped metal plate through the milling machine, so that the strip-shaped metal plate is initially formed; S2: Welding work. Then, place the initially formed strip-shaped metal plate on the welding machine, and then align the prepared T-shaped support block 10 with the notch surface opened on the elevator sill main body 1. Then, weld the vertical ends of the elevator sill main body 1 and the T-shaped support block 10 through the welding machine. Then, sequentially weld the prepared first slideway member 5 and second slideway member 6 on the surface of the rectangular notch, and at the same time, weld the prepared elevator door slide rail 3 on the upper surface of the elevator sill main body 1, so that the elevator sill made of the strip-shaped metal plate is initially formed; S3: Installation of the lining mechanism 8 structure. Then, install the lining mechanism 8 on the left side of the T-shaped support block 10, and weld the lower end of the support frame 803 to the horizontal upper surface of the T-shaped support block 10 through the welding machine. At the same time, connect the upper end of the upper pressing member 805 to the upper surface of the inner cavity of the side inner groove 7, then connect the lower end of the lower pressing member 806 to the lower surface of the inner cavity of the side inner groove 7, and then weld the upper surface of the insert sleeve 9 to the upper surface of the inner cavity of the side inner groove 7, so that the elevator sill is processed and completed.

[0046] Working principle: When installing the elevator sill main body 1, the plug-in member 203 is embedded in the side wall of the elevator shaft, and then the plug-in member 203 and the side wall of the elevator shaft are connected by pouring concrete. After the plug-in member 203 is poured, the first slide member 5 and the second slide member 6 at the notch of the elevator sill main body 1 are slidably connected to the first T-shaped slider 205 and the second T-shaped slider 206 on the embedded member 201, so that the elevator sill main body 1 and the connecting mechanism 2 can be initially connected. Then, the cap end of the bolt 11 is snapped into the T-shaped rail groove 4, and at the same time, the lower end of the bolt 11 is connected to the threaded hole 202 on the L-shaped guide member 207. At the same time, the nut is threadedly connected to the end of the bolt 11. In this way, the elevator sill main body 1 and the connecting mechanism 2 can improve the connection tightness through the embedded connection method, so that the support connection of the elevator sill main body 1 is more firm, and the service life of the elevator sill main body 1 can be enhanced; During the use of the elevator sill main body 1, when an external force is encountered, the external force squeezes the lower surface of the elevator sill main body 1. Then, when the elevator sill main body 1 is subjected to the external force, it can squeeze the upper pressing member 805. Then, the upper pressing member 805 squeezes the lower pressing member 806. In this way, the pressure on the upper surface of the elevator sill main body 1 can be weakened by the extrusion of the upper pressing member 805 and the lower pressing member 806, so as to avoid deformation of the elevator sill main body 1 caused by the external force, and at the same time avoid the deformation of the elevator door slide rail 3, which results in poor transmission performance of the elevator door sliding in the elevator door slide rail 3; After the pressure on the upper surface of the elevator sill main body 1 is weakened by the extrusion of the upper pressing member 805 and the lower pressing member 806, the lower pressing member 806 is pushed by the upper pressing member 805. Then, the lower pressing member 806 pushes the support plug-in member 801 rotatably connected on one side. Then, the chute 802 opened on the support plug-in member 801 can slide on the slide rod 804. Then, the support plug-in member 801 can be inserted into the plug-in set 9. The mutual clamping of the support plug-in member 801 and the plug-in set 9 can quickly support the deformed elevator sill main body 1 upward, so that the deformation of the elevator sill main body 1 only occurs locally, which can reduce the deformation amplitude of the elevator sill main body 1, thereby increasing the service life of the elevator sill main body 1. This is the working principle of the above-mentioned elevator sill.

[0047] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.

Then, sequentially weld the prepared first slide member (5) and the second slide member (6) on the surface of the rectangular notch. At the same time, weld the prepared elevator door slide rail (3) on the upper surface of the elevator sill body (1). In this way, the elevator sill made of the strip-shaped metal sheet is initially formed. S3: Installation of the inner lining mechanism (8) structure. Then, install the inner lining mechanism (8) on the left side of the T-shaped support block (10). Weld the lower end of the support frame (803) to the horizontal upper surface of the T-shaped support block (10) by using a welding machine. At the same time, connect the upper end of the upper pressing member (805) to the upper surface of the inner cavity of the side inner groove (7). Then, connect the lower end of the lower pressing member (806) to the lower surface of the inner cavity of the side inner groove (7). Then, weld the upper surface of the plug-in kit (9) to the upper surface of the inner cavity of the side inner groove (7). In this way, the processing of the elevator sill is completed.
