Technical Field

[0001] The utility model relates to the technical field of elevator installation, and more specifically, the utility model relates to an elevator installation platform. Background Art

[0002] An elevator refers to a mechanical and electrical device that uses a rigid guide rail to run a box body or a ladder (step) running along a fixed line to lift or horizontally transport people and goods, including passenger (cargo) elevators, escalators, and moving walks. At present, when installing elevator equipment in an elevator shaft, operators need to use an installation platform to perform high-altitude operations in the elevator shaft.

[0003] At the present stage, when the installation platform is applied in the elevator shaft, the building steps are relatively cumbersome, which affects the construction progress. At the same time, because the built installation platform is an assembled structure, it is inconvenient to move the installation platform to the elevator entrance positions on different floors. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an elevator installation platform. The technical problem to be solved by the utility model is that the building steps of the installation platform are relatively cumbersome, which affects the construction progress, and at the same time, there is a technical problem of poor moving flexibility.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An elevator installation platform is arranged in an elevator shaft and includes a pair of clamping seats. A support diagonal beam is fixedly connected to each clamping seat. A platform board is erected on the pair of support diagonal beams. A lifting lug is arranged on the upper surface of the platform board. A pair of extended pedals are movably connected to the bottom of the platform board. A telescopic driving mechanism one for driving the pair of extended pedals to move relatively is arranged on the pair of support diagonal beams;

[0006] The bottom of each support diagonal beam is movably connected with a abutment frame. A telescopic driving mechanism two for driving the abutment frame to move along the length direction of the support diagonal beam is arranged on the pair of support diagonal beams.

[0007] In a preferred embodiment, a pair of struts are fixedly connected to the top of each support diagonal beam. The platform board is fixedly connected to the two pairs of struts; an anti-slip pattern is arranged on the top of the platform board.

[0008] In a preferred embodiment, a storage groove is formed in the top of the platform board. The lifting lug is rotatably connected to the storage groove in a damping manner.

[0009] In a preferred embodiment, a pair of slide rails one are fixedly connected to the bottom of the platform board. The pair of extended pedals are both slidably connected to the pair of slide rails one.

[0010] In a preferred embodiment, a plurality of beam rods are fixedly connected to a pair of support inclined beams. The first telescopic driving mechanism includes a self-locking motor I fixedly installed on one of the beam rods, a swing arm fixedly connected to the output end of the self-locking motor I, and a pair of connecting rods hinged to the swing arm. The end of the connecting rod facing away from the swing arm is hinged to the extended pedal, and the swing arm is rotatably connected to the bottom of the platform plate through a rotating shaft.

[0011] In a preferred embodiment, one end of the abutting frame is rounded, and a reinforcing rod is fixedly connected to a pair of abutting frames.

[0012] In a preferred embodiment, a second slide rail is fixedly connected to the bottom of each support inclined beam, and a slide seat is slidably connected to the second slide rail. The slide seat is fixedly connected to the bottom of the abutting frame.

[0013] In a preferred embodiment, the second telescopic driving mechanism includes a fixed beam fixedly connected to a pair of support inclined beams, a lead screw rotatably connected to the fixed beam through a bearing, a push plate threadedly connected to the lead screw, and a self-locking motor II fixedly connected to the fixed beam. The output end of the self-locking motor II is fixedly connected to one end of the lead screw, and the push plate is fixedly connected to a pair of abutting frames.

[0014] The technical effects and advantages of the present utility model are as follows:

[0015] 1. For an elevator installation platform of the present utility model, by integrally designing the frame structure of the installation platform, the construction steps of on-site erection in the elevator shaft can be reduced. The lifting lugs cooperate with external hoisting equipment for hoisting, so that the entire elevator installation platform can be vertically lifted in the elevator shaft to support and use at the elevator entrance positions on different floors, meeting the requirements of moving flexibility.

[0016] 2. For an elevator installation platform of the present utility model, by providing a clamping seat, it can be clamped to the wall at the bottom of the elevator entrance. By using the vertical surface of the clamping seat to abut and contact the wall, due to the inclined setting of the support inclined beams and the abutting frame abutting against the wall on the side facing away from the elevator entrance, the gravity on the platform plate can be evenly distributed on the supported walls to stabilize the support position of the platform plate. In addition, by adjusting the telescopic length of the abutting frame through the second telescopic driving mechanism, it can be adapted to abut and support elevator shafts with different rectangular dimensions.

[0017] 3. For an elevator installation platform of the present utility model, by providing the first telescopic driving mechanism and the extended pedal, since the size of the platform plate is smaller than the size of the elevator shaft entrance, controlling the first telescopic driving mechanism to drive a pair of extended pedals to unfold and approach the shaft wall can reduce the gap between the platform plate and the shaft wall, avoiding the problem of stepping into the void due to too large a gap.

[0018] It should be noted that since both the abutment frame and the extension pedal can be controlled by electric drive, the action efficiency is high, so that the elevator installation platform can be conveniently and quickly applied when installed in the elevator shaft.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following specific embodiments illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] With reference to Figures 1-5, the present utility model provides an elevator installation platform, which is arranged in an elevator shaft and includes a pair of clamping seats 1. The clamping seats 1 are arranged in an L-shaped structure and can be clamped on the wall with a vertical angle below the elevator opening. In other embodiments, an anti-slip pad can be arranged in the clamping seats 1 for use. A support inclined beam 2 is fixedly connected to each clamping seat 1, and a platform board 3 is erected on a pair of support inclined beams 2. A lifting lug 4 is arranged on the upper surface of the platform board 3, and the lifting lug 4 can be used in cooperation with a hoisting device for lifting. A pair of extended pedals 5 are movably connected to the bottom of the platform board 3, and the extended pedals 5 can increase the stepping area of the platform board 3, so as to reduce the gap between the platform board 3 and the shaft wall. A telescopic driving mechanism 6 for driving the pair of extended pedals 5 to move relative to each other is arranged on the pair of support inclined beams 2.

[0028] A pair of support rods 9 are fixedly connected to the top of each support inclined beam 2, and the platform board 3 is fixedly connected to the two pairs of support rods 9. The support rods 9 are used to fix the support position of the erected platform board 3.

[0029] Anti-slip lines 31 are arranged on the top of the platform board 3, and the anti-slip lines 31 can improve the anti-slip property of the surface of the platform board 3.

[0030] A storage groove 10 is opened on the top of the platform board 3, and the lifting lug 4 is rotatably connected to the storage groove 10 in a damping manner. The lifting lug 4 can be rotatably connected to the storage groove 10 through a damping rotating shaft. The damping connection method is convenient for damping and shaping the erected state of the lifting lug 4, so as to facilitate the connection of the hook of the hoisting device. When the lifting lug 4 is convenient for being connected and lifted in cooperation with the hoisting and transporting device, the lifting lug 4 can be conveniently stored in the storage groove 10, so as to avoid the problem that the operator stumbles on the platform board 3.

[0031] A pair of slide rails 11 are fixedly connected to the bottom of the platform board 3, and a pair of extended pedals 5 are both slidably connected to the pair of slide rails 11. The slide rails 11 can provide linear sliding support for the extended pedals 5.

[0032] A number of beam rods 21 are fixedly connected to the pair of support inclined beams 2. The telescopic driving mechanism 6 includes a self-locking motor 61 fixedly erected on one of the beam rods 21, a swing arm 62 fixedly connected to the output end of the self-locking motor 61, and a pair of connecting rods 63 hinged to the swing arm 62; the self-locking motor 61 is a self-locking rotary motor, and the end of the connecting rod 63 facing away from the swing arm 62 is hinged to the extended pedal 5. The swing arm 62 is rotatably connected to the bottom position of the platform board 3 through a rotating shaft, and the rotation of the swing arm 62 in cooperation with the rotation on the platform board 3 can stabilize the rotation state.

[0033] Specifically, the self-locking motor 61 is controlled to rotate through an external controller. Under the sliding cooperation of the slide rail 11 and the extended pedal 5, the rotation of the swing arm 62 can drive the pair of extended pedals 5 to perform an opening and closing movement through the connecting rod 63, so as to control the position of the extended pedal 5 close to the shaft wall, thereby reducing the gap between the platform board 3 and the shaft wall and avoiding the problem of stepping into the air due to too large a gap.

[0034] A abutting frame 7 is movably connected to the bottom of each supporting inclined beam 2, and a second telescopic driving mechanism 8 for driving the abutting frame 7 to move along the length direction of the supporting inclined beam 2 is arranged on a pair of supporting inclined beams 2.

[0035] One end of the abutting frame 7 is provided with a rounded corner. A reinforcing rod 14 is fixedly connected to a pair of abutting frames 7. For the abutting frame 7 with a rounded corner, one end thereof can abut against the well wall far away from the elevator, so as to provide an inclined angle support for the supporting inclined beam 2, so that the gravity on the platform plate 3 is distributed at the position of the clamping seat 1 and the abutting frame 7; the reinforcing rod 14 can strengthen the connection strength of a pair of abutting frames 7.

[0036] A second slide rail 12 is fixedly connected to the bottom of each supporting inclined beam 2. A slide seat 13 is slidably connected to the second slide rail 12. The slide seat 13 is fixedly connected to the bottom position of the abutting frame 7. The cooperation between the slide seat 13 and the second slide rail 12 can enable the abutting frame 7 to move linearly along the length direction of the supporting inclined beam 2.

[0037] The second telescopic driving mechanism 8 includes a fixed beam 81 fixedly connected to a pair of supporting inclined beams 2, a lead screw 82 rotatably connected to the fixed beam 81 through a bearing, a push plate 83 threadedly connected to the lead screw 82, and a second self-locking motor 84 fixedly connected to the fixed beam 81; the second self-locking motor 84 also adopts a self-locking rotary motor. The output end of the second self-locking motor 84 is fixedly connected to one end of the lead screw 82, and the push plate 83 is fixedly connected to a pair of abutting frames 7.

[0038] Specifically, controlled by an external controller, the second self-locking motor 84 is driven, and it drives the lead screw 82 to enable the push plate 83 to move linearly. In this way, the push plate 83 can drive the abutting frame 7 to linearly slide on the second slide rail 12, so that the end of the abutting frame 7 extends beyond the supporting inclined beam 2, so as to facilitate the rounded corner end of the abutting frame 7 to abut against the well wall, and cooperate with the clamping seat 1 to be clamped into the wall at the vertical position of the elevator opening. In this way, the platform plate 3 can be stably erected in the elevator shaft.

[0039] It should be noted that since the elevator installation platform of the present application realizes support by means of abutting and clamping, operators need to wear safety ropes when working on the platform plate 3. When it is necessary to adjust the use position of the elevator installation platform, at this time, it is necessary to control the abutting frame 7 and the extension pedal 5 to perform position storage. Since the structure of the elevator installation platform of the present application except for the positions of the abutting frame 7 and the extension pedal 5 is an integral structure, and since the size of the platform plate 3 is smaller than the size of the elevator shaft, by using a hoisting device at the top of the elevator shaft to lift the elevator installation platform, the elevator installation platform can be conveniently used in the elevator opening areas on different floors, meeting the convenience of movement.
