Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a lifting device for building structure construction. Background Technology

[0002] A hoist is a large mechanical device that transports materials by changing their potential energy, such as a mine hoist or a dam hoist. In a broader sense, elevators, overhead cranes, winches, gantry cranes, hoists, and gate hoists can all be called hoists. Hoists are widely used in building construction, for example, for material transport and to provide support for workers.

[0003] In the existing technology, during the use of scissor lifts, the support portion gradually decreases and the support area gradually shifts to one side, resulting in low stability, high risk, and inconvenience in the use of scissor lifts. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, the support part of the scissor hoist gradually decreases and the support area gradually moves to one side during use, resulting in low stability, high danger and inconvenience of use. Therefore, a hoisting device for building structure construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting device for building structure construction, comprising a base, a lifting seat above the base, a reinforcing seat fixedly connected to one side of the lower end of the lifting seat, a support plate in the middle of one side of the upper end of the base, a second screw fixedly connected to the middle of the upper end of the support plate, a limit nut threadedly connected to the outer surface of the second screw, a first screw rotatably connected to the middle of the lower end of the reinforcing seat, a connecting sleeve threadedly connected to the outer surface of the first screw, a sleeve below the connecting sleeve, the connecting sleeve rotatably connected to the upper end of the sleeve, and a second side connector installed on one side of the sleeve.

[0006] Preferably, a bottom connecting block is fixedly connected to the lower end of the support plate, and a connecting groove is provided in the middle of one side of the upper end of the base.

[0007] Preferably, sliding grooves are provided on both sides of the connecting groove, and the two ends of the bottom connecting block are movably connected to the two sliding grooves respectively.

[0008] Preferably, a No. 1 side connector is fixedly connected to both sides of the base, and a No. 2 reinforcing rib is fixedly connected to both sides of the middle part of the No. 1 side connector.

[0009] Preferably, a reinforcing rib is fixedly connected to both sides of the middle part of the lower end of the base.

[0010] Preferably, end frames are fixedly connected to both sides of the upper end of the base, and a lifting frame is installed between the end frames and the lifting seat.

[0011] Preferably, a hydraulic cylinder is installed inside the lifting frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a No. 1 screw, a sleeve, and a No. 2 screw, when providing support, the connecting sleeve is connected to the No. 1 screw, then the sleeve is moved so that the No. 2 screw is placed inside the sleeve, and then the No. 2 side connector is connected to the sleeve. The limiting nut is rotated so that the limiting nut contacts the lower end of the sleeve. In this way, one side of the lifting seat can be supported, increasing the stability of use. Moreover, the structure is relatively simple, the production difficulty is low, and the use is convenient.

[0014] 2. In this utility model, the No. 1 side connector is designed to increase the contact area between the base and the ground, thereby further increasing the stability of use. The No. 1 side connector and the base are designed to be detachable, allowing the moving components to be disassembled. This avoids the possibility of movement and eliminates the need to suspend the lower end of the base, resulting in higher stability. The No. 2 screw is movable through the connection groove and sliding groove. When no support is needed, the No. 2 screw can be slid out and connected to the handle for use. This reduces the overall material usage and production costs. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a lifting device for building structure construction, including a base 1, a lifting seat 8 above the base 1, a reinforcing seat 12 fixedly connected to one side of the lower end of the lifting seat 8, a support plate 11 in the middle of one side of the upper end of the base 1, a second screw 16 fixedly connected to the middle of the upper end of the support plate 11, a limit nut 17 threadedly connected to the outer surface of the second screw 16, a first screw 9 rotatably connected to the middle of the lower end of the reinforcing seat 12, a connecting sleeve 19 threadedly connected to the outer surface of the first screw 9, a sleeve 10 below the connecting sleeve 19, the connecting sleeve 19 rotatably connected to the upper end of the sleeve 10, and a second side connector 18 installed on one side of the sleeve 10.

[0023] The specific setup and function of this embodiment are described below. With the arrangement of screw 9, sleeve 10 and screw 16, during support, connecting sleeve 19 is connected to screw 9, sleeve 10 is moved so that screw 16 is placed inside sleeve 10, and side connector 18 is connected to sleeve 10. The limiting nut 17 is rotated so that it contacts the lower end of sleeve 10. In this way, one side of the lifting seat 8 can be supported, increasing the stability of use. Moreover, the structure is relatively simple, has low production difficulty, and is convenient to use.

[0024] Example 2: Figure 1 - Figure 4 As shown, a bottom connecting block 13 is fixedly connected to the lower end of the support plate 11. A connecting groove 14 is provided in the middle of one side of the upper end of the base 1. Sliding grooves 15 are provided on both sides of the connecting groove 14. The two ends of the bottom connecting block 13 are movably connected to the two sliding grooves 15 respectively. A first side connecting seat 3 is fixedly connected to both sides of the base 1. A second reinforcing rib 4 is fixedly connected to both sides of the middle of the first side connecting seat 3. A first reinforcing rib 2 is fixedly connected to both sides of the middle of the lower end of the base 1. An end frame 5 is fixedly connected to both sides of the upper end of the base 1. A lifting frame 6 is installed between the end frame 5 and the lifting seat 8. A hydraulic cylinder 7 is installed inside the lifting frame 6.

[0025] The overall effect of this embodiment is that by setting the first side connector 3, the contact area between the base 1 and the ground is increased, thereby further increasing the stability of use. The first side connector 3 and the base 1 adopt a detachable design, so that the moving components can be disassembled, thus avoiding the possibility of movement. Moreover, this method does not require the lower end of the base 1 to be suspended in the air, resulting in higher stability. By setting the connecting groove 14 and the sliding groove 15, the second screw 16 can be moved. When no support is needed, the second screw 16 can be slid out and connected to the handle for use. In this way, the overall material usage is reduced, and the production cost is reduced.

[0026] The usage and working principle of this device are as follows: When support is required, first remove the movable structure so that the lower end of the base 1 and the first reinforcing rib 2 contacts the ground for support. Then connect the reinforcing seat 12 to the lifting seat 8, and then connect the connecting sleeve 19 to the lower end of the first screw 9. Next, start the hydraulic cylinder 7 and raise it to a suitable height. Push the second screw 16 towards the hydraulic cylinder 7 until the lower end face of the support plate 11 is in contact with the upper end face of the base 1. Then move the sleeve 10 so that the second screw 16 is inside the sleeve 10. Then install the second side connector 18 to the sleeve 10. Rotate the limiting nut 17 so that the upper end of the limiting nut 17 contacts the lower end of the sleeve 10. In this way, the first screw 9, the second screw 16, and the sleeve 10 support the lifting seat 8. Depending on the requirements, the first side connector 3 can be selectively installed before support.

[0027] The above are merely preferred embodiments of this utility model and are 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 for application in other fields. 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 the technical solution of this utility model shall still fall within the protection scope of this utility model.
