Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a building construction hoist. Background Technology

[0002] In construction, elevators are mainly used for vertical transportation of bricks, mortar, tools, and construction workers to improve construction efficiency and reduce the labor intensity of workers. Especially in bricklaying, the vertical transportation capacity of elevators can significantly reduce the time workers spend going up and down floors, while ensuring the timely supply of materials, thereby speeding up the construction progress.

[0003] During construction, existing hoists typically have a construction platform and a lifting frame that are fixedly connected or assembled with bolts. When faced with narrow construction entrances, this structural design often cannot be directly accessed due to the length limitation of the construction platform. The construction platform and lifting frame of the hoist must be disassembled and separated before it can enter the site, and then reassembled, which reduces construction efficiency. Utility Model Content

[0025] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0026] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 9 The present invention will be further described below.

[0027] A construction hoist includes: a base frame 1, with multiple casters rotatably connected to the bottom surface of the base frame 1, and a number of fixed frames 5 fixedly connected to the top surface of the base frame 1, with each pair of fixed frames 5 forming a group. A lifting frame 6 is slidably connected inside each group of fixed frames 5, and a first construction platform 7 is fixedly connected to the lifting frame 6. Second construction platforms 8 are respectively provided on both sides of the first construction platform 7, and inner grooves 11 are respectively opened on both sides of the first construction platform 7. The interior of the inner grooves 11 is slidably connected to the second construction platform 8. A retraction component is provided on one side of the first construction platform 7, and a guide component is provided inside the inner grooves 11. A positioning component is provided on the top surface of the first construction platform 7. A second electric push rod 13 is fixedly connected to the top surface of the base frame 1, and the output end of the second electric push rod 13 is fixedly connected to the first construction platform 7.

[0028] The retraction and deployment components include: a sliding hole 25, which is formed on the bottom surface of the first construction platform 7 and is connected to the inner groove 11; a second fixing block 28 is fixedly connected to one side of the first construction platform 7; a drive motor 26 is fixedly connected to one side of the second fixing block 28; the output end of the drive motor 26 passes through the second fixing block 28 and is fixedly connected to a bidirectional lead screw 12; a moving block 10 is fixedly connected to the bottom surface of the second construction platform 8; the interior of the moving block 10 is threadedly connected to the bidirectional lead screw 12; a first enclosure 9 is fixedly connected to the top surface of the second construction platform 8; a second locking hole 27 and a first locking hole 24 are formed on the top surface of the first construction platform 7 and are connected to each other; the second locking hole 27 and the first locking hole 24 are respectively connected to the inner groove 11.

[0029] Specifically, the retraction and extension components also include: a first fixing block 14, which is fixedly connected to one side of the first construction platform 7, and a bearing 15 is embedded in one side of the first fixing block 14. The inner ring of the bearing 15 is fixedly connected to the bidirectional lead screw 12.

[0030] In this embodiment, the bearing 15 reduces the friction of the bidirectional lead screw 12 when it rotates, thus ensuring the stability of the bidirectional lead screw 12's rotation.

[0031] Specifically, two support rods 2 are fixedly connected to both sides of the base frame 1. A first electric push rod 3 is embedded in one end of the support rod 2, and a support foot 4 is fixedly connected to the output end of the first electric push rod 3.

[0032] In this embodiment, the first electric push rod 3 is provided. The output end of the first electric push rod 3 extends and drives the support foot 4 to fit with the ground. Multiple support feet 4 lift the base frame 1, ensuring the stability of the base frame 1 during use.

[0033] Specifically, the guiding component includes two guide grooves 23, which are respectively opened on both sides of the inner groove 11. A guide block 22 is slidably connected inside the guide groove 23, and the guide block 22 is fixedly connected to the second construction platform 8.

[0034] In this embodiment, the guide block 22 is provided so that when the second construction platform 8 moves, the second construction platform 8 will drive the guide block 22 to slide inside the guide groove 23. The guide block 22 can ensure the stability of the movement of the second construction platform 8 and also play a guiding role.

[0035] Specifically, the positioning component includes: a second enclosure 16, which is located on the top surface of the first construction platform 7. A positioning frame 18 is fixedly connected to the top surface of the first construction platform 7. A fixing rod 17 is fixedly connected inside the positioning frame 18. A round hole is provided at one end of the second enclosure 16, and the other end of the second enclosure 16 is movably connected to the fixing rod 17 through the round hole.

[0036] Specifically, the positioning components also include: a positioning block 20, which is fixedly connected to one side of the second enclosure 16. The top surface of the positioning block 20 has a round hole, and a positioning rod 21 is movably inserted into the round hole. The top surface of the first construction platform 7 has a top hole 19, and the positioning rod 21 is movably inserted into the top hole 19.

[0037] In this implementation scheme, the second enclosure 16 can be rotated by the workers to open it by rotating it on the outer wall of the fixing rod 17. The workers can then stand on the first construction platform 7 or put construction materials on the first construction platform 7. The second enclosure 16 is then closed, and the positioning rod 21 is inserted into the top hole 19 through the round hole on the positioning block 20 to limit the second enclosure 16 and prevent it from opening. Then, the output end of the second electric push rod 13 extends to push the first construction platform 7, which in turn drives the lifting frame 6 and the second construction platform 8 to rise, thereby achieving the purpose of transporting workers or construction materials to a higher place.

[0038] The working principle and usage process of this utility model are as follows: During use, the base frame 1 can be moved via casters. When encountering a narrow construction entrance, the output end of the drive motor 26 rotates, driving the bidirectional lead screw 12 to rotate. Because the moving block 10 is limited by the sliding hole 25 and the inner groove 11, the moving block 10 changes from rotational motion to linear motion. Under the rotation of the bidirectional lead screw 12, the two moving blocks 10 are driven to bring the two second construction platforms 8 closer together and into the inner groove 11. Furthermore, as the second construction platforms 8 move, they move within the guide groove 23 via the guide block 22, thereby further... To ensure the stability of the movement of the second construction platform 8, when both second construction platforms 8 enter the inner groove 11, the two ends of the first enclosure 9 will respectively fit with the second locking hole 27 and the first locking hole 24, so that the two second construction platforms 8 retract into the inner groove 11. At this time, the workers can push the base frame 1 through the narrow construction entrance using the casters. Compared with the prior art, this application can simultaneously retract the two second construction platforms 8 into the inner groove 11 when the base frame 1 passes through the narrow construction entrance, thereby reducing the length of the first construction platform 7 and the second construction platform 8, and the overall operation is fast and will not affect the construction efficiency.

[0039] When the base frame 1 reaches the construction position via the casters, the drive shaft of the drive motor 26 rotates, driving the bidirectional lead screw 12 to rotate. The bidirectional lead screw 12 drives the two moving blocks 10 to move away from each other, thereby resetting the two second construction platforms 8. Then, the output end of the first electric push rod 3 extends, causing the support feet 4 to come into contact with the ground. The multiple support feet 4 lift the base frame 1, ensuring its stability during use. Then, the workers can rotate the second enclosure 16, which opens by rotating on the outer wall of the fixed rod 17. Workers can then stand on the first construction platform 7 or place construction materials on it. The second enclosure 16 is then closed, and the positioning rod 21 is inserted into the top hole 19 through the round hole on the positioning block 20 to limit the second enclosure 16 and prevent it from opening. Then, the output end of the second electric push rod 13 extends, pushing the first construction platform 7 to lift the lifting frame 6 and the second construction platform 8, thus achieving the purpose of transporting workers or construction materials to a higher position.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
