Description

Technical Field

[0001] This utility model relates to the field of construction safety engineering technology, and in particular to a balance beam device. Background Technology

[0002] In recent years, falls from heights have become one of the "five major injuries" in the construction industry, with a high incidence rate and extremely high risk. These accidents are highly unpredictable, and factors such as complex construction environments, numerous hazardous factors, inadequate protection, improper operating methods by workers, and management problems can all contribute to their occurrence. They often result in tragic casualties and property losses for the companies involved and the workers. To prevent falls from heights, it is crucial to ensure that on-site safety control measures are implemented effectively, providing workers with sufficient safety protection equipment and supervising their proper use. Furthermore, it is essential to train and test personnel engaged in work at heights, selecting only those suitable for such work.

[0003] Currently, various construction projects are widely promoting the construction of safety awareness education bases or safety experience centers, which also include facilities such as safety experience balance beams for workers to use for safety experience and training. However, most of these facilities are of a fixed shape and placed in a fixed setting, and the surrounding environment does not accurately reflect the complex working environment of the construction site. After using them, workers gradually become accustomed to the fixed structure of the balance beam, and when they actually face the on-site construction environment, they develop habitual movements and become complacent about their safety. This utility model aims to solve the problem of the limited usage scenarios of existing safety experience balance beams, allowing the slope and height of the balance beam to be freely adjusted, thereby enhancing the realism of safety experience and training and making the experience process closer to the actual working scenario.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1, referring to Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a balance beam device that can achieve the effect of adjusting the slope and height of the balance beam. It includes a balance beam mechanism 100, including a balance beam frame 101, balance beam legs 102 disposed on the balance beam frame 101, and a balance beam connecting plate 103 disposed on the balance beam legs 102.

[0032] The lifting mechanism 200 includes a lifting component 201 disposed in the balance beam support leg 102, and a drive component 202 disposed on the balance beam support leg 102 and the lifting component 201.

[0033] The limit protection mechanism 300 includes a protection component 301 disposed on the lifting component 201 and a limit component 302 disposed on the balance beam support leg 102;

[0034] The connecting mechanism 400 includes a pull ring connecting hole 401 provided on the balance beam frame 101 and the balance beam connecting plate 103, and a multi-angle connecting component 402 provided on the pull ring connecting hole 401;

[0035] The visual experience unit 500 includes a tempered glass panel 501 and an LED display screen 502 disposed on the tempered glass panel 501.

[0036] The LED display screen 502 is covered with a tempered glass panel 501 on top. The balance beam mechanism 100 is set on the tempered glass panel 501. Each balance beam frame 101 has multiple balance beam legs 102 at the bottom, which are connected at multiple angles by a multi-angle connecting component 402. Each balance beam frame 101 has an additional balance beam leg 102 on each side. The top of these additional balance beam legs 102 is fixed with a balance beam connecting plate 103. Pull ring connecting holes 401 are set at the end of the balance beam frame 101 and the balance beam connecting plate 103 that are close to each other, and there are multiple of them. The lifting mechanism 200 is set on the balance beam legs 102.

[0037] During use, the operator manipulates the drive component 202 to drive the lifting component 201 to move vertically up and down. At the same time, the limit component 302 ensures that the lifting component 201 is stable and vertically upward during the lifting process, so as to accurately adjust the height of the lifting component 201. The balance beam frame 101 relies on the multiple balance beam legs 102 configured at its bottom and the matching lifting component 201 to flexibly adjust its slope and height, thereby realizing the free adjustment of the height and slope of the balance beam structure. This effectively solves the problem of the single usage scenario mode of the safety experience balance beam and significantly improves the realism of the safety experience and training, making the experience more closely resemble the actual operating environment. In addition, the protective component 301 plays a protective role, effectively preventing accidental collisions between the lifting component 201 and the drive component 202. The design of the connecting mechanism 400 allows the balance beam frame 101 to achieve multi-angle rotational connection with the balance beam legs 102 and the balance beam connecting plate 103, facilitating the adjustment of the height and slope of the balance beam frame 101. Furthermore, the tempered glass panel 501 protects the LED display screen 502, which can switch between different work scene images according to usage needs, making the experience more realistic.

[0038] Example 2, refer to Figures 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a lifting assembly 201 including a lifting bracket 201a disposed inside the balance beam support leg 102, a connecting rod 201b disposed on the balance beam support leg 102, a lifting threaded block 201c disposed on the connecting rod 201b, and a lead screw 201d disposed on the balance beam support leg 102. The lifting bracket 201a is installed on the outside of the balance beam support leg 102 and is connected to the lifting threaded block 201c inside the balance beam support leg 102 through two connecting rods 201b. The lifting threaded block 201c and the lead screw 201d are threadedly connected.

[0039] Furthermore, the drive assembly 202 includes a drive rod 202a disposed on the balance beam leg 102, a turntable 202b and a drive bevel gear 202d disposed at both ends of the drive rod 202a, a crank 202c disposed on the turntable 202b, and a driven bevel gear 202e disposed on the lead screw 201d; wherein, the drive rod 202a is rotatably connected to the outer shell of the balance beam leg 102, the turntable 202b is located at the end of the drive rod 202a away from the balance beam leg 102, the drive bevel gear 202d is disposed at one end inside the balance beam leg 102, the drive bevel gear 202d and the driven bevel gear 202e are meshed together, and the driven bevel gear 202e is disposed at the lower end of the lead screw 201d.

[0040] Furthermore, the protective component 301 includes a first fixing rod 301a and a second fixing rod 301b disposed within the balance beam support leg 102, a first protective block 301c disposed on the first fixing rod 301a, and a second protective block 301d disposed on the second fixing rod 301b; wherein, the first protective block 301c is connected between the two first fixing rods 301a and fixed to the inner wall of the balance beam support leg 102, and similarly, the second protective block 301d is also fixed to the inner wall of the balance beam support leg 102 by the second fixing rod 301b, the first protective block 301c is located above the two bevel gears, and the second protective block 301d is located below the inner top surface of the balance beam support leg 102.

[0041] Furthermore, the limiting component 302 includes a limiting groove 302a disposed on the balance beam leg 102; wherein, two connecting rods 201b are respectively slidably connected in the corresponding limiting groove 302a, the limiting groove 302a is opened on the outer shell of the balance beam leg 102, and the width of the limiting groove 302a is the same as or slightly larger than that of the connecting rod 201b.

[0042] Furthermore, the balance beam support leg 102 has a bearing seat 205 embedded inside; wherein, the bearing seat 205 is located on the inner wall of the balance beam support leg 102 at both ends of the lead screw 201d, and both ends of the lead screw 201d are rotatably connected to the corresponding bearing seat 205.

[0043] Furthermore, both the first protective block 301c and the second protective block 301d have rod holes 206, the size of which is smaller than that of the lifting threaded block 201c; wherein, the rod holes 206 are located at the junction of the lead screw 201d and the first protective block 301c and the second protective block 301d, and the size of the rod holes 206 is larger than that of the lead screw 201d and smaller than that of the lifting threaded block 201c.

[0044] In use, the operator rotates the crank handle 202c and the turntable 202b, causing the drive rod 202a to drive the drive bevel gear 202d to rotate. The drive bevel gear 202d and the driven bevel gear 202e mesh, thus driving the lead screw 201d to rotate. The lead screw 201d is threadedly connected to the lifting threaded block 201c, and the connecting rods 201b on both sides of the lifting threaded block 201c are restricted in their direction of movement by the limiting grooves 302a, so that they can only drive the lifting bracket 201a to move upwards. The lifting mechanism is raised and lowered, and the lifting bracket 201a and the balance beam frame 101 are rotatably connected, thereby adjusting the slope and height of the balance beam frame 101. The bearing seat 205 supports and rotatably connects the lead screw 201d. The through hole 206 provides space for the lead screw 201d to prevent interference between the two. The first protective block 301c and the second protective block 301d can prevent the lifting threaded block 201c and the two bevel gears from colliding with the top of the balance beam support leg 102, thus providing protection.

[0045] Example 3, referring to Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a multi-angle connecting assembly 402, including a hook spring 402a disposed on a pull ring connecting hole 401, a support portion 402b disposed on the balance beam frame 101 and the lifting bracket 201a, and a connecting portion 402c correspondingly disposed on the bottom of the balance beam frame 101. The bottom of the balance beam frame 101 is equipped with multiple connecting portions 402c, each connecting portion 402c being rotatably connected to a support portion 402b. The lower parts of these support portions 402b are respectively and securely mounted on the corresponding lifting bracket 201a. Furthermore, multiple pull ring connecting holes 401 are carefully designed on both the balance beam frame 101 and the balance beam connecting plate 103 to allow the hooks at both ends of the hook spring 402a to be accurately installed and fixed in these holes.

[0046] Furthermore, a base 203 is provided below the balance beam support leg 102; wherein, the base 203 is a flat square block, and its horizontal projected area is much larger than that of the balance beam support leg 102.

[0047] Furthermore, a rubber block 204 is provided at the bottom of the base 203; wherein the size of the rubber block 204 is slightly larger than or equal to that of the base 203.

[0048] In use, the balance beam frame 101 and the balance beam connecting plate 103 are connected into a whole balance beam structure through the pull ring connecting hole 401 and the pull hook spring 402a. The balance beam frame 101 can be rotated at multiple angles, so that the whole balance beam structure composed of multiple balance beam frame 101 can be placed in the required usage scenario, thereby facilitating the safety experience and training of construction personnel. At the same time, the support part 402b and the connecting part 402c are rotatably connected to each other, so that the balance beam frame 101 and the balance beam support leg 102 can be rotatably connected together. This allows the balance beam frame 101 to change its slope, while the balance beam support leg 102 is vertically fixed to the tempered glass panel 501, thereby fixing the slope and height of the balance beam frame 101. The base 203 increases the contact area between the balance beam support leg 102 and the tempered glass panel 501 and lowers the center of gravity. In conjunction with the rubber block 204, the friction of the base 203 is increased, thereby improving the safety of the balance beam device.
