Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a construction hoist. Background Technology

[0002] Construction hoists, also known as construction lifts or construction elevators, are indispensable vertical transportation equipment in modern construction. They are mainly used to vertically transport personnel and materials within construction sites. With the acceleration of urbanization and the booming development of the construction industry, the demand for construction hoists is also increasing.

[0003] Some traditional lifting devices are difficult to move and require the use of other tools for transport, which increases deployment time and cost. In addition, the fixing methods of some traditional devices are not flexible enough and cannot effectively adapt to various terrains and conditions, resulting in the risk of the equipment tipping over or sliding during operation, which reduces the safety of the construction process.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a construction hoist that can ensure stability under different terrains and conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A construction hoist includes: a base, on both sides of the upper surface of the base, with mounting brackets fixedly connected to each side, and threaded screws rotatably connected to the rear sides of the interior of each mounting bracket, with lifting seats threaded onto the surfaces of each threaded screw, and a lifting platform fixedly connected between the two lifting seats; rotating seats fixedly connected to both sides of the front and back of the base, with a rotating rod rotatably connected inside the rotating seat, a support assembly at one end of the upper surface of the rotating rod, and a storage assembly fixedly connected to the middle end of the upper surface of the rotating rod.

[0008] Furthermore, the support assembly includes a support threaded hole at one end of the upper surface of the rotating rod, a support bolt adapted to the support threaded hole is threaded to one end of the upper surface of the rotating rod, a support plate is fixedly connected to the lower end of the support bolt, and a handle is fixedly connected to the upper end of the support bolt.

[0009] Furthermore, the storage component includes a connecting block fixedly connected to the middle of the upper surface of the rotating rod. The upper surface of the connecting block is provided with a fixing groove. Two connecting elastic plates are fixedly connected to the front and back of the base. One end of the upper surface of the connecting elastic plate is fixedly connected to a fixing block that matches the fixing groove.

[0010] Furthermore, a limit rod is fixedly connected to the front side inside both of the mounting brackets, and a limit groove adapted to the limit rod is opened on the front side of both of the lifting seats.

[0011] Furthermore, both the front and back of the lifting platform are hinged with protective doors, and a protective railing is fixedly connected to the upper surface of the lifting platform.

[0012] Furthermore, a drive motor is fixedly connected to the rear side of the upper surface of the mounting bracket, and the power end of the drive motor is fixedly connected to the threaded screw. Both of the lifting seats have threaded holes on their rear sides that are compatible with the threaded screw.

[0013] Furthermore, the lower surface of the base is fixedly connected with casters.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. Equipped with support components, the device can be easily moved around the construction site via the casters until it reaches the designated working position, increasing its flexibility, shortening deployment time, and improving construction efficiency. Upon reaching the target point, pressing the fixing block releases the rotating rod, which is then adjusted to the appropriate angle and secured with support bolts and a support plate. The operation is simple and quick, ensuring the device's stability under different terrains and conditions. The flexible adjustment of the four rotating rods adapts to different ground conditions, reducing the risk of tipping or sliding and improving safety during construction. Simultaneously, the adjustable support bolts ensure the support plate fits tightly against the ground, increasing the contact area between the device and the ground, further enhancing stability and preventing shaking during operation.

[0016] 2. Equipped with a storage component, during use, rotating the rotating rod utilizes the elastic properties of the connecting elastic plate to automatically spring the fixing block into the fixing groove of the connecting block, completing the storage of the rotating rod. The automatic spring-loaded design of the connecting elastic plate and the fixing block ensures the stability of the rotating rod during storage, preventing safety hazards caused by loosening or falling off the rotating rod during transportation or storage. This not only simplifies the storage process and improves the convenience of operation, but also significantly reduces the overall size of the elevator, thereby improving the space utilization rate of the equipment, helping to reduce the space occupied by the equipment, improve construction efficiency, and make the elevator more compact after storage, facilitating transportation and storage, and reducing equipment management and maintenance costs.

[0017] 3. Equipped with a lifting platform, when in use, the drive motor is started to rotate the threaded screw, thereby driving the lifting seat and lifting platform to rise smoothly. This lifting method is efficient and stable, ensuring the safety and comfort of construction personnel during the lifting process. At the same time, the movement of the lifting seat on the limit rod ensures the stability of the lifting process, making the lifting process of the device more stable and reliable, and reducing the risk of equipment failure.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] A type of construction hoist, such as Figure 1-4 As shown, the device includes a base 1, with mounting brackets 2 fixedly connected to both sides of the upper surface of the base 1. Threaded screws 3 are rotatably connected to the rear sides of the interior of each mounting bracket 2. Lifting seats 4 are threaded onto the surfaces of each of the two threaded screws 3. A lifting platform 5 is fixedly connected between the two lifting seats 4. Rotating seats 6 are fixedly connected to both sides of the front and back of the base 1. Rotating rods 7 are rotatably connected inside the rotating seats 6. A support component is provided at one end of the upper surface of the rotating rod 7, and a storage component is fixedly connected to the middle end of the upper surface of the rotating rod 7.

[0026] In an optional embodiment, the support assembly includes a support threaded hole 8 formed at one end of the upper surface of the rotating rod 7. A support bolt 9 adapted to the support threaded hole 8 is threaded to one end of the upper surface of the rotating rod 7. A support plate 10 is fixedly connected to the lower end of the support bolt 9, and a handle 11 is fixedly connected to the upper end of the support bolt 9. By adjusting the rotating rod 7 to a suitable angle, the support bolt 9 is rotated through the handle 11, driving the support plate 10 to move downward until it contacts the ground. The flexible adjustment of the four rotating rods 7 can adapt to different ground conditions, ensuring the stability of the equipment under different terrains and conditions.

[0027] In an optional embodiment, the storage assembly includes a connecting block 12 fixedly connected to the middle of the upper surface of the rotating rod 7. The upper surface of the connecting block 12 has a fixing groove 13. Two connecting elastic plates 14 are fixedly connected to the front and back of the base 1. One end of the upper surface of the connecting elastic plate 14 is fixedly connected to a fixing block 15 that matches the fixing groove 13. When the rotating rod 7 is rotated, the fixing block 15 is automatically ejected into the fixing groove 13 of the connecting block 12 by utilizing the elastic properties of the connecting elastic plate 14, thus completing the storage of the rotating rod 7. The automatic ejection design of the connecting elastic plate 14 and the fixing block 15 ensures the stability of the rotating rod 7 during the storage process.

[0028] In an optional embodiment, limit rods 16 are fixedly connected to the front sides of both mounting brackets 2, and limit grooves 17 adapted to the limit rods 16 are provided on the front sides of both lifting seats 4. The movement of the lifting seat 4 on the limit rods 16 not only restricts its left and right swaying but also ensures the stability during the lifting process. This design makes the lifting process more stable and reliable, reducing the risk of equipment failure.

[0029] In an optional embodiment, the front and back of the lifting platform 5 are hinged with protective doors 18, and the upper surface of the lifting platform 5 is fixedly connected with a protective railing 19.

[0030] In an optional embodiment, a drive motor 20 is fixedly connected to the rear side of the upper surface of the mounting bracket 2, and the power end of the drive motor 20 is fixedly connected to the threaded screw 3. The rear sides of the two lifting seats 4 are provided with connecting threaded holes 21 that are compatible with the threaded screw 3.

[0031] In an optional embodiment, a movable wheel 22 is fixedly connected to the lower surface of the base 1. The drive motor 20 is configured to provide power by rotating the threaded screw 3. The movable wheel 22 enables the device to move easily on the construction site until it reaches the designated working position.

[0032] In this embodiment, the elevator is first moved to the target point via the moving wheels 22. After reaching the target point, the fixing block 15 is pressed down and moved downwards, thereby releasing the fixing block 15 from the fixing groove 13 of the connecting block 12, releasing the fixing of the rotating rod 7. After rotating the rotating rod 7 to a suitable angle, the handle 11 drives the support bolt 9 to rotate, thereby driving the support plate 10 to move downwards until it contacts the ground. The above steps are repeated to rotate all four rotating rods 7 around the base 1 to a suitable angle, thereby stably fixing the device in place. Then, the worker uses a safety device to... The protective door 18 enters the lifting platform 5, and the drive motor 20 is started to drive the threaded screw 3 to rotate. The rotation of the threaded screw 3 can drive the lifting seat 4 and the lifting platform 5 to move upward. At the same time, the front side of the lifting seat 4 moves on the limit rod 16. After use, rotate the support bolt 9 to release the support plate 10. Rotate the rotating rod 7 again to let the connecting elastic plate 14 and the fixing block 15 be inserted into the connecting block 12 until the connecting elastic plate 14 pushes the fixing block 15 into the fixing groove 13 of the connecting block 12 to complete the fixation. Repeat the above steps to store all the rotating rods 7.
