Description

Technical Field

[0001] This invention relates to the field of safety hook and hanger technology for construction sites, and specifically provides a mobile safety hook and hanger for building construction sites. Background Technology

[0002] The "Classification of Work at Heights" standard stipulates that any work performed at a height of 2 meters or more above the reference plane where there is a possibility of falling is considered work at height. All relevant construction workers must wear safety belts, and the safety belts should be attached high and used low to ensure stability and security. However, in traditional building construction sites, when performing work near edges or installing equipment at height, there is often a problem of safety hooks not being properly secured.

[0003] Chinese patent CN116350964A discloses a movable safety hook bracket for building construction sites, comprising a main body with several hook holes, a friction-fixing top seat at the top, and a lifting device at the bottom, mounted on a movable base. The movable base has retractable pulleys, and both the bottom of the movable base and the top of the friction-fixing top seat have friction surfaces. The lifting device is used to lift the main body, creating friction between the top of the friction-fixing top seat and the bottom of the movable base and the upper and lower floor slabs respectively, meeting the fall load requirements of workers accidentally falling. While this patented technology allows for movement and fixation on construction sites, it does not solve the problem of side impacts after a fall. Summary of the Invention

[0004] The purpose of this invention includes providing a mobile safety hook frame for building construction sites that is more stable under downward pulling force, less prone to lateral collisions when falling, and flexible and convenient to move.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a mobile safety hook frame for building construction sites, comprising a boom, a support rod, an electric screw jack, a top support plate, and a bottom support plate. The top support plate is connected to the top of the electric screw jack; the bottom support plate is connected to the bottom of the electric screw jack; one end of the boom has a hook hole, and the other end has a shaft hole, with several insertion holes between the hook hole and the shaft hole; the boom is connected to the top support plate through the shaft hole; one end of the support rod is connected to the bottom support plate through a shaft, and the other end is connected to the insertion hole on the boom through a pin.

[0007] Preferably, the base support plate includes a base body, and a sliding sleeve is connected to the upper middle part of the base body; the outer wall of the sliding sleeve is provided with a shaft for connecting one end of the support rod, and the shaft of the sliding sleeve is provided with a rod insertion hole; the rod insertion hole passes through the base body; and a groove is provided on the lower middle part of the base body.

[0008] Preferably, the base support also includes wheels, which are connected to the side of the chassis body via wheel frames.

[0009] Preferably, the number of wheels (53) is two.

[0010] Preferably, the top support plate includes a top plate body, and a connector for connecting to a shaft hole at one end of the boom is connected to the lower middle part of the top plate body.

[0011] Preferably, anti-slip rubber sheets are connected to the top of the top support plate and the bottom of the bottom support plate.

[0012] Preferably, the top plate body further includes bolts, which are vertically threaded onto the top plate body and located away from the hook hole.

[0013] Preferably, the electric screw jack includes a motor, a sleeve with a protruding ring and a plug at the bottom, a screw inserted into the sleeve, a worm gear transmission module connected to the upper end of the sleeve, a battery connected to the sleeve wall, and a controller. The motor housing is connected to the outside of the worm gear transmission module, and the motor's output shaft is connected to the worm on the worm gear transmission module. The motor and the battery are electrically connected to the controller. The plug is inserted into the plug hole. The top end of the screw is connected to the lower end of the connector on the top support plate.

[0014] Preferably, the lower end of the insertion rod is connected to a plug to prevent the insertion rod from falling out of the insertion rod hole.

[0015] Preferably, the boom is a telescopic boom.

[0016] Due to the adoption of the above technical solutions, the advantages of this invention are as follows:

[0017] 1. The fixing of the upper and lower floor slabs in this invention is not only achieved through the tightening action of the electric screw jack, but also when the boom is subjected to a downward force acting on the support rod, the support rod pushes the chassis body towards the end cap, and the electric screw jack tends to extend, so that the invention is further clamped between the upper and lower floor slabs, making the safety hook frame provided by this invention more difficult to fall off and tip over, thus providing multiple guarantees for the safety performance of this invention;

[0018] 2. This invention can ensure that the hook hole is basically located directly above the construction worker by adjusting the length of the boom, thus preventing the risk of lateral collision if the construction worker falls.

[0019] 3. In this invention, one end of the boom and the strut are respectively connected to the top support plate and the bottom support plate, which can reduce the stress on the middle of the electric screw jack, thereby enabling the electric screw jack to provide higher load-bearing capacity;

[0020] 4. By further installing bolts on the top plate body, the present invention can ensure the stable positioning of the present invention by tightening or preventing the top plate body from moving;

[0021] 5. The present invention has fewer components and does not contain a hydraulic system, and can be easily moved flexibly by pulling after folding;

[0022] 6. The present invention has a simple structure and is easy to manufacture. Attached Figure Description

[0038] The embodiment of the electric screw jack (30) provided by the present invention is shown in the figure below. Figure 1 , Figure 2 , Figure 3 The device includes a motor (33), a sleeve (34) with a protruding ring (35) and a plug rod (36) at the bottom, a lead screw (31) inserted into the sleeve (34), a worm gear transmission module (32) connected to the upper end of the sleeve (34), a battery (4) connected to the wall of the sleeve (34), and a controller (5). The housing of the motor (33) is connected to the outside of the worm gear transmission module (32), and the output shaft of the motor (33) is connected to the worm on the worm gear transmission module (32). The motor (33) and the battery (4) are electrically connected to the controller (5). The plug rod (36) is inserted into the plug rod socket (54). The top end of the lead screw (31) is connected to the lower end of the connector (42) on the top support plate (40).

[0039] The embodiment of the bottom support plate (50) provided by the present invention is shown in the figure below. Figure 1 , Figure 2 It includes two wheels (53), anti-slip rubber sheet (7) and chassis body (52). A sliding sleeve (51) is connected to the upper part of the middle of the chassis body (52). The outer wall of the sliding sleeve (51) is provided with a shaft (2) for connecting one end of the support rod (20). The shaft of the sliding sleeve (51) is provided with a rod insertion hole (54). The rod insertion hole (54) passes through the chassis body (52). A groove (521) is provided on the lower part of the middle of the chassis body (52). The two wheels (53) are connected to the side of the chassis body (52) through a wheel frame. The anti-slip rubber sheet (7) is connected to the lower part of the chassis body (52).

[0040] Working principle of the invention:

[0041] This invention uses an electric screw jack (30) to press against the upper floor slab and the lower floor slab (70) to achieve conventional fixation of the safety hook bracket; by adjusting the telescopic boom (10), it ensures that the hook hole (11) is basically located directly above the construction worker, ensuring that the construction worker is not prone to lateral collision after falling; by movably connecting the lower end of the support rod (20) to the sliding sleeve (51), it achieves the function of adjusting the boom (10) after the construction worker falls. The downward force is transmitted to the sliding sleeve (51) through the support rod (20), which in turn presses the bottom support plate (50) against the lower floor slab (70). As the boom (10) is subjected to the downward force, the base body (52) moves toward the end cap (6), and the electric screw jack (30) tends to extend and is further clamped between the upper floor slab and the lower floor slab (70), making it more difficult for the movable building construction site safety hook frame provided by the present invention to fall off and tip over. In addition, bolts (8) are also provided on the top plate body (41), which can further ensure the stable positioning of the present invention by tightening or preventing the top plate body (41) from moving.

[0042] When using this invention, pull the folded version of the invention to the construction site. Then, depending on the height of the construction site and the location where the invention can be fixed, connect the end of the support rod (20) with the pin (1) to the appropriate insertion hole (12) on the boom (10) through the pin (1). Adjust and position the length of the boom (10) to ensure that the hook hole (11) is basically located directly above the construction personnel.

[0043] To fix the electric screw jack (30), clean the debris on the floor slab (70) where the invention is to be placed, face the hook hole (11) toward the construction area, and then use the hand to lift the top support plate (40) and sleeve (34) to erect the invention on the floor slab (70). Extend the electric screw jack (30) through the controller (5) and place it between the floor slab (70) and the upper floor slab, or place the electric screw jack (30) between the floor slab (70) and the beam (60). (When the width of the beam (60) is less than the width of the top plate body (41), tighten the bolt (8) on the top plate body (41) to a height above the top plate body (41), and adjust the position of the bottom support plate (50) so that the side of the bolt (8) contacts the inner side of the beam (60). See [link to relevant documentation].] Figure 5 The jacking force of the electric screw jack (30) can be determined by experimentally determining the most suitable motor power range to ensure that the friction force between the top support plate (40) and the bottom support plate (50) and the floor meets the requirements of the fall load.

[0044] During the hanging construction, after the construction workers hold up the safety hook and attach it to the hook hole (11), they can enter the high-altitude construction work platform (80) to carry out the work.

[0045] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
