Description

Technical Field

[0001] Embodiments of the present disclosure relate to an elevator installation platform. Background Art

[0002] The elevator installation platform is used for installing an elevator in a shaft. The installation platform is hoisted by a motor and a steel rope without being guided by a track. After the installation platform is lifted to a designated position, it is used for drilling and installing a track. During this process, the installation platform is only suspended in the air by ropes and has no support around it, resulting in it being very unstable. Therefore, there are certain safety hazards in performing installation operations on the installation platform.

[0003] In addition, there are various sizes of shafts. When the elevator installation platform is smaller than the shaft size, the installation platform is prone to tilting and does not fully utilize the operating space in the shaft. When the elevator installation platform is larger than the shaft size, the elevator installation platform cannot be placed in the shaft and thus cannot be used. In order to adapt to various shaft sizes, it is necessary to provide elevator installation platforms of various sizes, resulting in high costs, complex operations, and long working cycles.

[0004] Therefore, there is a need for an elevator installation platform that has stability during lifting and stopping, can adapt to various shaft sizes, and has improved safety. Summary of the Utility Model

[0029] Figure 1 and Figure 2Respectively shown is a perspective view of an elevator installation platform according to an embodiment of the present disclosure. As Figure 1 and Figure 2 shown, the elevator installation platform includes a frame having a fence bracket 110 and a support bracket 140, a ceiling 150, a support wheel assembly 120 and a push rod assembly 130 mounted on the frame.

[0030] As Figure 1 and Figure 2 shown, the fence bracket 110 includes a bottom plate 113, a first upright post 1111, a second upright post 1112, a third upright post 1113, a fourth upright post 1114, a first horizontal railing 1121, a second horizontal railing 1122, a third horizontal railing 1123 and a fourth horizontal railing 1124, which together define a platform space 170. An operator can stand in the platform space 170 to perform operations such as drilling holes in the shaft and installing tracks, and / or various machines can be placed in the platform space 170 to perform operations such as drilling holes and installing tracks automatically or by the operator. The first upright post 1111, the second upright post 1112, the third upright post 1113 and the fourth upright post 1114 are respectively arranged at the four corners of the bottom plate 113. The first horizontal railing 1121 is connected between the first upright post 1111 and the second upright post 1112 at the left side of the bottom plate 113 and extends in the front-rear direction. The second horizontal railing 1122 is connected between the third upright post 1113 and the fourth upright post 1114 at the right side of the bottom plate 113 and extends in the front-rear direction. The third horizontal railing 1123 is connected between the first upright post 1111 and the third upright post 1113 at the front side of the bottom plate 113 and extends in the left-right direction. The fourth horizontal railing 1124 is connected between the second upright post 1112 and the fourth upright post 1114 at the rear side of the bottom plate 113 and extends in the left-right direction. A door 160 is arranged at the front side of the fence bracket 110 and at the middle part of the third horizontal railing 1123. The operator can enter the platform space 170 through the door 160.

[0031] The fence bracket 110 is configured to be able to change its size in the front-rear direction and / or the left-right direction to change the size of the elevator installation platform (and its platform space 170). Therefore, the elevator installation platform can change the size of its fence bracket 110 according to the size of the shaft, so as to adapt to the size of the shaft. After the shaft size is determined, the size of the platform space 170 can be fully enlarged, thereby providing a larger operation space for the operator and the operating machine. For example, the size of the elevator installation platform can be adjusted to be slightly smaller than the size of the shaft. In addition, without manufacturing another elevator installation platform, the size of the elevator installation platform can be adaptively adjusted according to the shaft size, saving costs and shortening the working cycle of installing the elevator.

[0032] In this embodiment, the fence bracket 110 is configured to be able to change its dimensions in the front - rear direction and the left - right direction. Specifically, for example, the first transverse rail 1121 and the second transverse rail 1122 are configured to be telescopable in the front - rear direction, so as to change the dimension of the platform space 170 in the front - rear direction, and the third transverse rail 1123 and the fourth transverse rail 1124 are configured to be telescopable in the left - right direction, so as to change the dimension of the platform space 170 in the left - right direction. In other embodiments, the fence bracket 110 may be configured to be able to change its dimensions in only one of the front - rear direction and the left - right direction. For example, only the first transverse rail 1121 and the second transverse rail 1122 are configured to be telescopable in the front - rear direction while the third transverse rail 1123 and the fourth transverse rail 1124 are not telescopable, or only the third transverse rail 1123 and the fourth transverse rail 1124 are configured to be telescopable in the left - right direction while the first transverse rail 1121 and the second transverse rail 1122 are not telescopable.

[0033] As Figure 2 shown, the first transverse rail 1121, the second transverse rail 1122, and the fourth transverse rail 1124 each include a first sub - rod portion 11221, a second sub - rod portion 11222, and a locking member 11223. The second sub - rod portion 11222 has a through - hole (or groove), and the first sub - rod portion 11221 is received in the through - hole, such that the corresponding transverse rail can be telescoped by changing the degree to which the first sub - rod portion 11221 is received in the through - hole. The locking member 11223 is provided at the end of the through - hole of the second sub - rod portion 11222 where the opening is located, for locking the degree to which the first sub - rod portion 11221 is received in the through - hole.

[0034] As Figure 1 shown, the door 160 is provided on the front side of the elevator installation platform. Two sub - parts of the third transverse rail 1123 are respectively provided on both sides of the door 160. Figure 3 Illustrated is Figure 1 a perspective view of a sub - part of the third transverse rail 1123 of the elevator installation platform in Figure 3 shown. As

[0035] The first horizontal railing 1121, the second horizontal railing 1122, the third horizontal railing 1123, and the fourth horizontal railing 1124 may also have other retractable configurations, and the present disclosure is not limited thereto.

[0036] Figure 4 shows Figure 1 a perspective view of the bottom portion of the elevator installation platform in Figure 4 As shown, retractable bottom sliders 114 are also provided around the bottom plate 113 of the elevator installation platform to cooperate with the retraction of the corresponding horizontal railings.

[0037] Return Figure 1 , the elevator installation platform further includes a support bracket 140 and a ceiling 150. The support bracket 140 is fixed to the bottom plate 113 and extends in the up-down direction perpendicular to the front-back direction and the left-right direction beyond the fence bracket 110.

[0038] Figure 5 shows Figure 1 a perspective view of the top portion of the elevator installation platform in Figure 1 and Figure 5 As shown, the ceiling 150 is mounted on top of the support bracket 140 and has a first ceiling panel 151 and a second ceiling panel 152. The first ceiling panel 151 and the second ceiling panel 152 are rotatably connected about a third rotation axis 153 at an angle that can be changed with respect to each other. Thus, by adjusting the angle between the first ceiling panel 151 and the second ceiling panel 152, the size of the ceiling 150 can be adjusted corresponding to the size of the fence bracket 110 so that the ceiling 150 can sufficiently shield the platform space 170 of the fence bracket 110 from above. Thus, falling objects in the shaft can be prevented from falling into the platform space 170, protecting the safety of the operators and equipment in the platform space 170. In this example, the third rotation axis 153 is parallel to the front-back direction, but the present disclosure is not limited thereto, and the third rotation axis 153 may also be parallel to the left-right direction.

[0039] As Figure 5As shown, the elevator installation platform includes a ceiling support rod assembly, which includes four ceiling support rods 180 that are installed at the corners of the support bracket 140 and extend in the vertical direction. The first side and the second side of the first ceiling board 151 and the third side and the fourth side of the second ceiling board 152 are respectively provided with a plurality of mounting holes 1511 and 1521 that are arranged at intervals. The ceiling support rod 180 located at the right front side and the ceiling support rod 180 located at the right rear side can be selectively connected to one of the plurality of mounting holes 1511 on the first side and one of the plurality of mounting holes on the second side 1511 respectively. The ceiling support rod 180 located at the left front side and the ceiling support rod 180 located at the left rear side can be selectively connected to one of the plurality of mounting holes 1521 on the third side and one of the plurality of mounting holes on the fourth side respectively. Therefore, the angle between the first ceiling board 151 and the second ceiling board 152 can be adjusted by adjusting the connection positions of the ceiling support rods 180 with the mounting holes 1511 and 1521 on the sides of the corresponding ceiling boards.

[0040] As Figure 5 shown, the four ceiling support rods 180 are provided with a plurality of mounting holes 181 that are arranged at intervals in the vertical direction, and the support bracket 140 can be selectively connected to one of the plurality of mounting holes 181 of each ceiling support rod 180. Therefore, the height of the ceiling 150 can be adjusted by adjusting the connection positions of the support bracket 140 with the mounting holes 181 of the corresponding ceiling support rod 180.

[0041] Return Figure 1 , the elevator installation platform further includes a support wheel assembly 120. Four support wheel assemblies 120 are installed at the four corners of the fence bracket 110. Specifically, the four support wheel assemblies 120 can be respectively fixed to the first vertical column 1111, the second vertical column 1112, the third vertical column 1113, and the fourth vertical column 1114. Each of the four support wheel assemblies 120 includes a support wheel 122 that can rotate around a rotation axis parallel to the front-rear direction. When the elevator installation platform is hoisted in the shaft. The support wheel 122 can roll against the wall surface of the shaft to improve the smoothness of the elevator installation platform when moving in the shaft.

[0042] In addition, another four support wheel assemblies 120 can be respectively fixed to the four corners of the top of the support bracket 140. Each of the four support wheel assemblies 120 includes a support wheel 122 that can rotate around a rotation axis parallel to the front-rear direction. Therefore, the another four support wheel assemblies 120 further improve the smoothness of the elevator installation platform when moving in the shaft. Figure 6 Shows Figure 1A perspective view of the sliding bracket assembly 141 located at the top of the support bracket 140. The sliding bracket assembly 141 includes a fixed mounting portion 1411 fixed to the support bracket 140 and a movable portion 1412 movably mounted to the fixed mounting portion 1411 in the left-right direction. The other four support wheel assemblies 120 are mounted to the movable portion 1412. Thus, the four support wheel assemblies 120 can be moved in the left-right direction to adapt to the size of the shaft. For example, the movable portion 1412 can be moved relative to the fixed mounting portion 1411 by selectively fixing screws to the mounting holes of the movable portion 1412 of the fixed mounting portion 1411.

[0043] Furthermore, another four support wheel assemblies 120 can be respectively fixed to the four corners of the elevator installation platform. Each of the four support wheel assemblies 120 includes a support wheel 122 that can rotate about a rotation axis parallel to the left-right direction. Thus, the four support wheel assemblies 120 further improve the smoothness of the elevator installation platform in the left-right direction when moving in the shaft.

[0044] Figure 7 and Figure 8 respectively show Figure 1 a perspective view and a plan view of the support wheel assembly 120 in Figure 7 and Figure 8 As shown in Figure 1 , the support wheel assembly 120 includes a first mounting bracket 121 (see Figure 7 ), an intermediate mounting bracket 123, a connecting rod 124, a support wheel 122, and an elastic biasing member 125. For clarity, the first mounting bracket 121 is removed in Figure 7 and Figure 8 . The intermediate mounting bracket 123 is mounted to the fence bracket 110 via the first mounting bracket 121. The connecting rod 124 is mounted to the intermediate mounting bracket 123 such that it can rotate about a first rotation axis 126. The support wheel 122 is mounted to the end of the connecting rod 124 and can rotate about a second rotation axis 127 parallel to the first rotation axis 126. The elastic biasing member 125 is used to bias the connecting rod 124 toward the outside of the fence bracket 110, thereby biasing the support wheel 122 mounted to the connecting rod 124 toward the outside of the fence bracket 110. By providing the elastic biasing member 125, the support wheel 122 can roll on the uneven wall in the shaft, further improving the smoothness of the elevator installation platform during operation. When the support wheel 122 rolls onto a protrusion on the wall of the shaft, the wall pushes the support wheel 122 toward the inside of the elevator installation platform against the biasing force of the spring biasing member 125. When the support wheel 122 passes over the protrusion, the spring biasing member 125 biases the support wheel 122 toward the wall so that the support wheel 122 continues to roll against the wall.

[0045] The resilient biasing member 125 can be a helical spring extending in a first direction 128 perpendicular to the second rotational axis 127. The support wheel assembly 120 further includes an abutting portion 1272 and a spring support rod 1271 extending in the first direction 128. The spring support rod 1271 passes through a through hole 1273 provided in the abutting portion 1272. The helical spring can be disposed at least partially around the spring support rod 1271. One end of the helical spring is rotatably connected to a substantially middle position of the connecting rod 124. The other end of the helical spring is connected to the abutting portion 1272. The abutting portion 1272 can be fixed to the middle mounting bracket 123. Alternatively, the abutting portion 1272 can be movable relative to the middle mounting bracket 123 in the first direction 128 to adjust the compression degree of the helical spring.

[0046] The first mounting bracket 121 is fixed to the fence bracket 110, and the middle mounting bracket 123 is mounted to the first mounting bracket 121 through a lead screw nut mechanism such that the middle mounting bracket 123 can slide relative to the first mounting bracket 121 in the first direction 128. Thus, based on adjusting the size of the platform space 170 of the fence bracket 110, the position of the support wheel 122 relative to the fence bracket 110 can be further flexibly adjusted so that the support wheel 122 can abut against the wall at a proper position in various shaft sizes. Specifically, the lead screw 1281 is mounted on an L-shaped member 1211 fixed to the first mounting bracket 121 and is configured to be rotatable relative to the L-shaped member 1211 but not translatable. The nut 1282 is fixed to the middle mounting bracket 123. By rotating the lead screw 1281, the nut 1282 and the middle mounting bracket 123 are translated relative to the first mounting bracket 121 in the first direction 128.

[0047] Return Figure 1 , and the elevator installation platform further includes four push rod assemblies 130, which are respectively mounted to four corners of the fence bracket 110. Figure 9 Shown is Figure 1 a perspective view of the push rod assembly 130 in Figure 9As shown, each push rod assembly 130 includes a second mounting bracket 131, a push rod motor 132, and a push rod 133. The second mounting bracket 131 is fixed to the fence bracket 110. The push rod motor 132 is fixed to the second mounting bracket 131. The push rod 133 is driven by the push rod motor 132 to extend and retract in the left-right direction. When the elevator installation platform moves to a specific height position in the shaft, the push rod 133 can be extended towards the wall to abut against the wall, so that the elevator installation platform is fixed to the specific height position by the frictional force between the end of the push rod 133 and the wall. In this embodiment, the push rod motor 132 is configured to continuously provide an extending force to the push rod 133. Therefore, compared with the case where the push rod motor 132 only drives the push rod 133 to extend without continuously providing an extending force, since the extending force is continuously provided to the push rod 133, the push rod 133 can abut against the wall more firmly to fix the elevator installation platform to a specific position in the shaft.
