Description
Technical Field
[0001] This utility model relates to the field of elevator technology, specifically an elevator used in building construction. Background Technology
[0002] A construction hoist is a common piece of construction equipment, primarily used for the vertical transport of personnel, materials, or equipment on construction sites. It effectively improves construction efficiency, especially during high-rise building construction. Self-elevating hoists are characterized by the fact that they do not require external support during lifting; the equipment itself rises and falls according to the needs of the construction. They are typically equipped with a hydraulic drive system, enabling them to complete lifting and lowering in a short time. They are suitable for temporary, high-efficiency construction tasks, primarily used for exterior facade work in high-rise building construction, such as window frame installation and exterior wall construction.
[0003] Patent document CN221625756U discloses a lifting platform for building construction, comprising: a base, with foldable support legs on both sides of the upper part of the base, and a work platform above the foldable support legs; a first stepper motor is mounted on the upper surface of the base, and a first lead screw is coaxially mounted on the rotor of the first stepper motor, with a drive block screwed to the surface of the first lead screw; and a second stepper motor is disposed on both sides of the upper surface of the base, with a second lead screw coaxially mounted on the rotor of the second stepper motor, and a lifting rod screwed to the surface of each second lead screw, with a support plate mounted on the top of each lifting rod. The added second stepper motor can drive the second lead screw to rotate, and the rotation of the second lead screw can drive the lifting rod to move upward, supporting both sides of the work platform, effectively preventing the work platform from loosening, and improving the stability of the device.
[0004] However, when in use, this device is difficult to effectively intercept tools or materials falling during operations, which can easily cause injury to personnel below. It is also inconvenient to store and increases the space it occupies. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A hoist for building construction includes a base and a platform. Several sets of support frames are fixedly connected to the surface of the platform. Rollers are rotatably connected inside the support frames, and steel wire ropes are slidably connected to the surfaces of the rollers. A drive assembly is fixedly connected to one end of the steel wire rope. Rotary seats are fixedly connected to both sides of the base. Support assemblies are rotatably connected to the surface of each rotating seat. The drive assembly includes a rotating shaft fixedly connected to one end of the steel wire rope, and a drive motor fixedly connected to one end of the rotating shaft. The support assembly includes a rotating rod rotatably connected to the surface of the rotating seat. A rotating joint is rotatably connected to one end of the rotating rod, and a fixed seat is rotatably connected to one end of the rotating joint. A threaded rod is threadedly connected inside the fixed seat, and a support is rotatably connected to the bottom of the threaded rod.
[0008] Preferably, the other end of the wire rope is fitted with a connecting ring, and a protective net is fixedly connected to the bottom of the connecting ring. The protective net can be flexibly opened and closed as the elevator rises to form a three-dimensional protective barrier to prevent tools or materials from falling.
[0009] Preferably, the protective net is hinged to the bottom of the platform, and a connecting cloth is fixedly connected to one side of the protective net. The connecting cloth serves as an auxiliary fixing component to protect the connection point of the protective net.
[0010] Preferably, a folding bracket is rotatably connected to the inner wall of the base, and a support seat is fixedly connected to the top of the folding bracket. The support seat is fixedly connected to the bottom of the platform, and the support seat serves as a force transmission node to distribute the platform load to the base.
[0011] Preferably, a support plate is fixedly connected to the inner side of the base, and a limit block is fixedly connected to the top surface of the support plate, the limit block supporting the hydraulic push rod;
[0012] Preferably, a hydraulic push rod is fixedly connected to one side of the limiting block, and the output end of the hydraulic push rod is fixedly connected to the bottom of the folding bracket. The hydraulic push rod pushes the bottom of the folding bracket to provide power support.
[0013] Preferably, a motor housing is fitted onto the surface of the drive motor, and a support shell is fixedly connected to one side of the motor housing. The support shell is fixedly connected to the surface of the platform, and the support shell facilitates the rotation of the rotating shaft.
[0014] Preferably, the surfaces of the rotating base and the rotating rod are provided with several sets of limiting holes in a circular array, and limiting pins are inserted into the inside of the limiting holes. The bottom of the base is provided with four sets of universal wheels, and the surface of the four sets of universal wheels is covered with polyurethane material for easy movement.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This utility model, through the setting of the drive component, allows the platform to be close to the working wall on one side during use. Then, the hydraulic push rod is activated to drive the folding bracket to extend and adjust the platform height. Then, during operation, the drive motor is activated to drive the rotating shaft to loosen the wire rope. The protective net then pulls the wire rope by its own weight and is rolled and transmitted through the rollers, unfolding at the bottom of the platform. This effectively intercepts tools or materials falling during operation, preventing injury to personnel below. At the same time, it is easy to store and reduces the space occupied.
[0017] 2. This utility model, through the setting of the support component, allows for the following operation: During use, the rotating rod is pulled according to the ground conditions, causing one end of the rotating rod to rotate to a suitable position on the rotating seat. Then, a limiting pin is inserted into the corresponding limiting hole to fix the angle of the rotating rod. The threaded rod is then rotated within the fixed seat, pressing against the support and providing support on the ground. Simultaneously, depending on the local inclination of the ground, the fixed seat uses a rotating joint to deflect at a certain angle, keeping the support in contact with the ground. This adapts to different terrain requirements, effectively solving the adaptability problem of traditional support devices under complex ground conditions, and combining flexibility and safety.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a technical solution: a hoist for construction, including a base 1 and a platform 2. Several sets of support frames 3 are fixedly connected to the surface of the platform 2. Rollers 4 are rotatably connected inside the support frames 3, and steel wire ropes 5 are slidably connected to the surfaces of the rollers 4. A drive assembly 6 is fixedly connected to one end of the steel wire rope 5. The drive assembly 6 effectively intercepts falling tools or materials during operation, preventing injury to personnel below, and also facilitates storage and reduces space occupation. Rotary seats 7 are fixedly connected to both sides of the base 1, and support assemblies 8 are rotatably connected to the surfaces of the rotating seats 7. It adapts to different terrain requirements, effectively solves the problem of adaptability of traditional support devices under complex ground conditions, and has both flexibility and safety. The drive component 6 includes a rotating shaft 601 fixedly connected to one end of the wire rope 5, and a drive motor 602 fixedly connected to one end of the rotating shaft 601; the support component 8 includes a rotating rod 801 rotatably connected to the surface of the rotating seat 7, a rotating joint 802 rotatably connected to one end of the rotating rod 801, a fixed seat 803 rotatably connected to one end of the rotating joint 802, a threaded rod 804 internally threadedly connected to the fixed seat 803, and a support 805 rotatably connected to the bottom of the threaded rod 804.
[0025] Please see Figure 2 The other end of the wire rope 5 is fitted with a connecting ring 9, and a protective net 10 is fixedly connected to the bottom of the connecting ring 9; the protective net 10 is hinged to the bottom of the platform 2, and a connecting cloth 11 is fixedly connected to one side of the protective net 10.
[0026] The connecting ring 9 serves as a transition connector at the end of the wire rope 5. It can withstand dynamic loads and distribute stress, and facilitates the pulling of the protective net 10. The protective net 10 is hinged to the bottom of the platform 2 and can be flexibly opened and closed as the elevator rises, forming a three-dimensional protective barrier to prevent tools or materials from falling. The net material has high impact resistance and can effectively buffer the impact of sudden falling objects without affecting the operator's vision. The connecting cloth 11 serves as an auxiliary fixing component. It absorbs vibration through elastic material to prevent the hinge of the protective net 10 from loosening due to frequent swinging, and also protects the connection of the protective net 10.
[0027] Please see Figure 2A folding bracket 12 is rotatably connected to the inner wall of the base 1, and a support seat 13 is fixedly connected to the top of the folding bracket 12. The support seat 13 is fixedly connected to the bottom of the platform 2. A support plate 14 is fixedly connected to the inner side of the base 1, and a limit block 15 is fixedly connected to the top surface of the support plate 14. A hydraulic push rod 16 is fixedly connected to one side of the limit block 15, and the output end of the hydraulic push rod 16 is fixedly connected to the bottom of the folding bracket 12.
[0028] The folding bracket 12 is rotatably connected to the inner wall of the base 1 via a hinge structure, enabling the platform 2 to move up and down under the drive of the hydraulic push rod 16. When unfolded, it forms a stable triangular support structure, ensuring the mechanical stability of the elevator under load. The top-fixed support seat 13 serves as a force transmission node, rigidly connecting to the bottom of the platform 2 to convert the telescopic movement of the folding bracket 12 into vertical displacement, while distributing the load of the platform 2 to the base 1. The support plate 14 serves as a rigid support for the limiting block 15, which supports the hydraulic push rod 16. The hydraulic push rod 16 pushes the bottom of the folding bracket 12 to provide power support.
[0029] Please see Figure 3 and Figure 4 The surface of the drive motor 602 is fitted with a motor housing 17, and a support housing 18 is fixedly connected to one side of the motor housing 17. The support housing 18 is fixedly connected to the surface of the platform 2. The surfaces of the rotating seat 7 and the rotating rod 801 are provided with several sets of limiting holes in a circular array. Limiting pins 19 are inserted into the inside of the limiting holes. Four sets of universal wheels 20 are provided at the bottom of the base 1.
[0030] The motor housing 17 protects the surface of the drive motor 602, the support housing 18 supports the rotation of the shaft 601, the rotating seat 7 and the rotating rod 801 are limited in angle by inserting the limiting pin 19 through the limiting hole on the surface, and the four sets of universal wheels 20 are covered with polyurethane material for easy movement.
[0031] Working principle: During use, one side of the platform 2 is close to the working wall, and the hydraulic push rod 16 is activated to extend the folding bracket 12 and adjust the height of the platform 2. During operation, the drive motor 602 is activated to drive the rotating shaft 601 to loosen the wire rope 5. The protective net 10 then pulls the wire rope 5 by its own weight, and the wire rope 5 is rolled and transmitted through the roller 4, unfolding at the bottom of the platform 2. During use, depending on the ground conditions, the rotating rod 801 is pulled so that one end of the rotating rod 801 rotates to a suitable position on the rotating seat 7. The limiting pin 19 is then inserted into the corresponding limiting hole to fix the angle of the rotating rod 801. The threaded rod 804 is then rotated so that the threaded rod 804 rotates within the fixed seat 803 and presses against the support 805, supporting it on the ground. At the same time, depending on the local tilt of the ground, the fixed seat 803 is deflected at a certain angle using the rotating joint 802 to keep the support 805 in contact with the ground. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
