Description

Technical Field

[0001] The invention relates to a simple lifting platform device, in particular to a movable lifting platform device which can be used for tunnel construction. Background Art

[0002] During tunnel construction, traditional tunnel excavation requires blasting with explosives, so the process of filling the explosives is extremely important, and filling the explosives requires assembling brackets, but assembling the brackets will take a lot of time, greatly delaying the progress of excavation. Some people will think of using aerial vehicles and trolleys to replace the brackets, but the internal volume of the tunnel is too small to accommodate the aerial vehicles and trolleys, and the cost will also be greatly increased. Therefore, this utility model patent designs a movable lifting platform to solve this problem. Summary of the invention

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a movable lifting platform device. To achieve this goal, the present invention proposes a technical solution, which is characterized in that the device has the characteristics of simple structure, convenient installation and convenient transportation. In addition, the design of the present invention can also carry out blasting work while ensuring the safety of blasting personnel.

[0004] On the basis of the above technical solution, the present invention relates to a movable lifting platform device, which mainly includes a lifting platform, a protective shed and a supporting structure. A slide rail is provided on the top of the lifting platform, including a track, a pulley and a dustproof shell, mainly to prevent dust from entering and causing the friction of the pulley to increase, affecting the lateral movement of the platform. The platform lifting is controlled by a hydraulic rod. An operating platform and a lifting baffle are provided at the bottom of the lifting platform. The hydraulic rod controls the lifting and lowering of the baffle to protect the safety of construction workers. In order to ensure the safety of workers, a protective shed is also provided, including a spliced ​​slide rail and a protective baffle to prevent falling rocks during construction. The supporting structure is located above the lifting platform and is composed of universal wheels and iron pipes. When in use, it can be freely combined according to actual needs.

[0005] Compared with traditional lifting devices, the advantages of this device are as follows:

[0006] 1. Convenient transportation: This device can be disassembled into multiple parts, which greatly reduces the transportation volume and also reduces the transportation cost.

[0007] 2. Simple structure: The device has a simple structure, consisting only of a lifting platform, a protective shed and a supporting structure, which can be easily and quickly assembled, thus shortening the working time.

[0008] 3. Wide range of applications: The device is flexibly designed and can flexibly adjust the platform height according to the height and type of the tunnel. The device has great flexibility.

[0009] 4. High economic benefits: The detachability of the device greatly reduces the transportation cost. At the same time, the quick assembly of the device also reduces the working time. The device can be used multiple times, which reduces the use of raw materials compared to traditional brackets.

[0010] In summary, the present invention utilizes hydraulic rods to increase the load-bearing capacity of the lifting platform, which can ensure that multiple personnel can work on the lifting platform at the same time. The protective shed and the supporting structure play a role of protection and support, and can protect the safety of personnel when dangerous situations occur in the tunnel.

[0019] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the present invention provides a design of a movable lifting platform device, including a lifting platform (1), a protective shed (2) and a supporting structure (3). Wherein: a slide rail is provided on the top of the lifting platform (1), including a track (4), a pulley (5) and a dust cover (6), and the track (4) is laid along the top edge of the platform to provide a stable moving path for the pulley (5). The dust cover (6) tightly covers the outside of the slide rail and the pulley, effectively preventing dust generated during the construction process from entering the slide rail system, thereby ensuring the smooth operation of the pulley (5). An operating platform (11) and a lifting baffle (12) are provided at the bottom of the platform for construction personnel to stand and work. The protective shed (2) comprises a spliced ​​slide rail (15) and a protective baffle (16); the platform lifting is controlled by a hydraulic rod 1 (7), a hydraulic rod 2 (8), a hydraulic rod 3 (9) and a small hydraulic rod (10), and the lifting and lowering height of the lifting platform is accurately controlled by the hydraulic rods to meet the needs of different construction scenes; the lifting and lowering of the baffle is controlled by the small hydraulic rod (10); the support structure (3) is located above the lifting platform (1) and is composed of a universal wheel (13) and an iron pipe (14).

[0021] When in use, the platform is moved horizontally by the track (4) and the pulley (5), which is convenient for construction workers to work. When the platform rises, the hydraulic rod 1 (7), the hydraulic rod 2 (8), the hydraulic rod 3 (9) and the small hydraulic rod (10) are used for control.

[0022] In order to prevent accidents, the present invention further comprises a lifting baffle (12) and a protective baffle (16); the lifting baffle (12) is arranged on the operating platform (11) and is controlled by a small hydraulic rod (10) to prevent people from accidentally falling; the protective baffle (16) is arranged on the protective shed (2) to resist dangerous factors such as falling rocks and splashing objects during the construction process, thereby ensuring the life safety of construction workers.

[0024] This embodiment provides a design of a movable lifting platform device, which mainly includes a lifting structure, a supporting structure and additional functional components. Preferably, a spacious operating platform (11) is provided at the bottom of the lifting structure, and a liftable baffle (12) is provided at the front end or edge of the operating platform (11), and the baffle is controlled to be lifted and lowered by a small hydraulic rod (10). When the platform is in a non-operating state, the lifting baffle (12) is in a closed position to prevent people from accidentally falling; during the operation process, the lifting baffle (12) can be opened as needed to facilitate construction personnel to enter and exit or transfer materials.

[0025] Preferably, the support structure of the device provides stable support for the entire device. The structure is mainly composed of a universal wheel (13) and an iron pipe (14). The universal wheel (13) is installed at the bottom of the support structure so that the device can be flexibly moved to a specified position in the tunnel. The iron pipe (14) is fixed on the top of the universal wheel (13) by welding, bolting, etc. to form a stable support frame. The design of the support structure fully considers the space limitation and load-bearing requirements of the tunnel to ensure the stability and safety of the device during operation. Through this design, application scenarios such as tunnel construction that require frequent movement and lifting operations are met, providing a safe and convenient working environment for construction personnel, and achieving efficient operation and safety protection during construction.
