Description

Technical Field

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

[0002] The elevator installation platform is used to install an elevator in a shaft. The installation platform is hoisted by a lifting motor and a steel rope. After the installation platform is lifted to a designated position, it is used for drilling and installing rails.

[0003] The existing elevator installation platform only relies on the self-locking function of the lifting motor itself to prevent falling, and the safety is poor.

[0004] 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 tilt, and the operating space in the shaft is not fully utilized. 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.

[0005] Therefore, there is a need for an elevator installation platform that has improved safety and can adapt to various shaft sizes. Summary of the Utility Model

[0006] At least one embodiment of the present disclosure provides an elevator installation platform, which includes: a support bracket; a rope for suspending the support bracket; a lifting motor for winding at least one of the ropes to lift and lower the support bracket in a shaft; and a safety lock through which at least one of the ropes extends, the safety lock being configured to lock and hold a part of at least one of the ropes.

The fence bracket includes: a bottom plate, to which the support bracket is fixed and extends upward and downward beyond the fence bracket; a first transverse railing and a second transverse railing that extend in the front-rear direction perpendicular to the up-down direction and are respectively located on the left and right sides of the bottom plate; and a third transverse railing and a fourth transverse railing that extend in the left-right direction perpendicular to the front-rear direction and the up-down direction and are respectively located on the front and rear sides of the bottom plate. The bottom plate, the first transverse railing, the second transverse railing, the third transverse railing, and the fourth transverse railing jointly define the platform space of the fence bracket. The third transverse railing and the fourth transverse railing are configured to be able to expand and contract in the left-right direction, thereby changing the size of the platform space in the left-right direction, and / or the first transverse railing and the second transverse railing are configured to be able to expand and contract in the front-rear direction, thereby changing the size of the platform space in the front-rear direction.

[0012] For example, in some embodiments, the fence frame further includes a first column, a second column, a third column, and a fourth column. The first transverse railing is connected between the first column and the second column, the second transverse railing is connected between the third column and the fourth column, the third transverse railing is connected between the first column and the third column, and the fourth transverse railing is connected between the second column and the fourth column.

[0013] For example, in some embodiments, the elevator installation platform further includes a ceiling. The ceiling is installed on the top of the support bracket such that the lifting motor and the safety lock are located between the ceiling and the fence bracket in the up-down direction. The ceiling has a first roof panel and a second roof panel, and the first roof panel and the second roof panel are connected such that the two can rotate around a third rotation axis to form a variable angle with each other.

[0028] Figure 1 and Figure 2 respectively show perspective views 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 support 110 and a support support 140, a ceiling 150, a lifting motor 120 and a safety lock 130 mounted on the support support 140.

[0029] As Figure 1 and Figure 2As shown, the fence support 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 support 110 and at the middle part of the third horizontal railing 1123. The operator can enter the platform space 170 through the door 160.

[0030] The fence support 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 support 110 according to the size of the shaft, so as to adapt to the size of the shaft. After the size of the shaft is determined, the size of the platform space 170 can be fully enlarged, thus providing a larger operating 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.

[0031] In this embodiment, the fence support 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 able to expand and contract in the front - rear direction, thereby changing 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 able to expand and contract in the left - right direction, thereby changing the dimension of the platform space 170 in the left - right direction. In other embodiments, the fence support 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 able to expand and contract in the front - rear direction while the third transverse rail 1123 and the fourth transverse rail 1124 cannot, or only the third transverse rail 1123 and the fourth transverse rail 1124 are configured to be able to expand and contract in the left - right direction while the first transverse rail 1121 and the second transverse rail 1122 cannot.

[0032] 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 into the through - hole such that the corresponding transverse rail can be expanded and contracted by changing the degree to which the first sub - rod portion 11221 is received into the through - hole. The locking member 11223 is provided at the end where the opening of the through - hole of the second sub - rod portion 11222 is located, and is used to lock the degree to which the first sub - rod portion 11221 is received into the through - hole.

[0033] 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 Shows 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 shown, this sub - part includes a first sliding member 11231 fixed to the door 160, a second sliding member 11232 fixed to the first upright post 1111, and a screw 11233. The first sliding member 11231 is provided with a plurality of circular through - holes. The second sliding member 11232 is provided with one or more elongated through - holes that extend in the left - right direction. The screw 11233 passes through the elongated through - hole of the second sliding member 11232 and one of the circular through - holes at the same time. The screw 11233 can slide in the elongated through - hole such that the first sliding member 11231 can slide relative to the second sliding member 11232, thereby causing the expansion and contraction of the third transverse rail 1123.

[0034] 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.

[0035] Figure 4 shows Figure 1 a perspective view of the bottom portion of the elevator installation platform in Figure 4 As shown, around the bottom plate 113 of the elevator installation platform, retractable bottom sliders 114 are also provided to cooperate with the retraction of the corresponding horizontal railings.

[0036] 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.

[0037] 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 the 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 to form 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. Therefore, 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.

[0038] 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 panel 151 and the third side and the fourth side of the second ceiling panel 152 respectively have a plurality of mounting holes 1511 and 1521 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 panel 151 and the second ceiling panel 152 can be adjusted by adjusting the connection positions of the ceiling support rods 180 and the mounting holes 1511 and 1521 on the sides of the corresponding ceiling panels.

[0039] As Figure 5 shown, the four ceiling support rods 180 have a plurality of mounting holes 181 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 position of the support bracket 140 and the mounting hole 181 of the corresponding ceiling support rod 180.

[0040] As Figure 1 、 Figure 2 and Figure 5 shown, the elevator installation platform further includes a rope (not shown), a pulley 141, a lifting motor 120, and a safety lock 130. The rope is used to suspend the support bracket 140 and the fence bracket 110. The lifting motor 120 is used to wind at least one of the ropes to lift and lower the elevator installation platform in the hoistway. At least one of the ropes extends through the safety lock 130, and the safety lock 130 is configured to lock and hold a part of the at least one rope. The prior art only relies on the anti-falling function of the lifting motor 120 itself to ensure the safety of the elevator installation platform. The elevator installation platform according to an embodiment of the present disclosure is further provided with a safety lock 130 for additionally locking and holding a part of the rope used to suspend the support bracket 140. Therefore, the safety of the elevator installation platform is improved. For example, when the elevator installation platform is no longer in operation, or rather, during the non-working time of the elevator installation platform, the lifting motor 120 is turned off, and the safety lock 130 can be locked to ensure the safety of the elevator installation platform during this period.

[0041] In addition, the lifting motor 120 and the safety lock 130 are fixed to the top of the support bracket 140. Compared with the situation in the prior art where the lifting motor 120 is arranged at the bottom of the installation platform and in the fence bracket 110, arranging the lifting motor 120 at the top of the support bracket 140 can prevent the large-sized lifting motor 120 from occupying the space of the platform space 170 in the fence bracket 110, so as to provide a larger space for the operator to operate and place equipment.

[0042] Figure 6 shows Figure 1 a schematic diagram of a part of the support bracket 140 in Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the support bracket 140 includes two gantry bracket parts 143 in a square shape, which are respectively arranged on the front side and the rear side. In this embodiment, the elevator installation platform is provided with two lifting motors 120 and two safety locks 130. One lifting motor 120 and one safety lock 130 are arranged on the top of one gantry bracket part 143 located on the front side, and the other lifting motor 120 and the other safety lock 130 are arranged on the top of the other gantry bracket part 143 located on the rear side. Since there are two lifting motors 120, compared with the situation where only one lifting motor 120 is arranged, when the lifting capacity is the same, the volume and weight of a single lifting motor 120 can be reduced, which is beneficial to safely installing the lifting motor 120 on the top of the gantry bracket part 143. In addition, arranging the two lifting motors 120 and the two safety locks 130 on both sides of the elevator installation platform respectively helps to balance the weight distribution of the elevator installation platform. Additionally, as Figure 1 , Figure 2 and Figure 6 shown, a plurality of rope guiding tubes 142 and a plurality of pulleys 141 are fixed to the support bracket 140. The rope guiding tube 142 is an elongated tubular structure, which at least partially extends in the direction from the top to the bottom and is used for guiding the rope. The pulley 141 is used for guiding and changing the extending direction of the rope.

[0043] Figure 7 shows a schematic diagram of the lifting motor 120, the safety lock 130 and the rope according to an embodiment of the present disclosure. As Figure 7As shown, in this embodiment, the elevator installation platform may include two pairs of ropes. Each pair of ropes corresponds to a pair of lifting motors 120 and safety locks 130. Each pair of ropes includes a first rope 191 and a second rope 192. The first rope 191 extends from the upper machine room, sequentially passes through the lifting motor 120, the pulley 141, and the rope guide tube 142, and is connected to the lower counterweight. The second rope 192 extends from the upper machine room, sequentially passes through the safety lock 130, the pulley 141, and the rope guide tube 142, and is connected to the lower counterweight. Therefore, the improvement of the safety by the safety lock 130 can be achieved with a simple arrangement. However, the ropes may be arranged in other ways, and the present disclosure is not limited thereto.
