Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a mobile installation device for explosion-proof doors. Background Art

[0002] Explosion-proof doors are widely used in various industrial sites, such as chemical plants, refineries, military factories, and some special military facilities and underground projects. Their main function is to be able to quickly withstand the shock wave generated by the explosion in the event of an explosion, thereby protecting the safety of people and equipment in the building. Due to the high installation precision requirements and the difficulty of construction, slight deviations may affect the performance of the explosion-proof door and may even cause it to fail to function properly in the event of an explosion. Therefore, the installation quality of the explosion-proof door is of vital importance. Explosion-proof doors are usually large in size and heavy in weight. Existing explosion-proof door installation mainly uses hoisting technology. The detailed hoisting plan is determined based on factors such as the weight, size, and installation location of the explosion-proof door. During the hoisting process, a dedicated person is required to command to ensure the coordination and safety of the hoisting operation. In addition, necessary safety protection measures must be taken, such as wearing safety belts and setting up safety warning signs.

[0003] Existing technologies have drawbacks and shortcomings: 1. Limitations of hoisting equipment: Heavy blast-resistant doors require hoisting equipment for transport and installation. However, existing hoisting equipment may have limitations in lifting weight, lifting height, and operational flexibility, making it inadequate for the installation of some large blast-resistant doors. For example, in cramped construction sites, hoisting equipment may not be able to enter smoothly, or the hoisting space may be limited, making it impossible to accurately place the blast-resistant door in the intended installation location. This can result in suboptimal installation results, impacting installation efficiency and quality.

[0004] 2. Lack of specialized installation tools: Currently, the installation of explosion-resistant doors relies primarily on general-purpose installation tools and lacks specialized installation mechanisms. This makes the installation of key components more difficult and the quality of installation difficult to guarantee. For example, when installing heavy explosion-resistant doors, the height and horizontal position must be constantly adjusted. Traditional hoisting methods require numerous personnel and cannot be fixed in advance, resulting in unstable or inaccurate installation positions, which affects the performance of the explosion-resistant doors.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings, but this does not limit the scope of protection of the present invention.

[0028] Example 1:

[0029] The explosion-proof door mobile installation device of this scheme is made of high-strength square steel welded as a whole. The maximum load-bearing capacity of the mechanism is 10 tons. It can realize flexible movement in the horizontal direction and can achieve a maximum stroke of 150mm in the vertical direction.

[0030] The main frame is welded with high-strength steel and mainly consists of a large base plate 1, two columns 2, two sets of brackets and a lifting mechanism 3.

[0031] Base 1: Made of high-strength steel, it has sufficient bearing capacity and stability.

[0032] The base 1 is fitted with multiple lockable universal wheels 101, bolted to the four corners of the main frame. These secure connections are capable of supporting the weight of the mounting frame and explosion-proof door, making it easy to move and secure the mounting frame. Each universal wheel 101 is equipped with a brake to help secure the mounting frame during installation.

[0033] The two columns 2 are made of high-strength steel and are vertically welded to the base 1. The welding joints are firm and reliable, and the stability of the overall structure is guaranteed.

[0034] Bracket component 3: The main body of the bracket component 3 is divided into a vertical bracket 401 and a sliding bracket 402. The vertical bracket 401 is mounted on the column 2 through the mounting pin 403. When the hydraulic jack 301 is working, it drives the mobile weighing frame and the vertical bracket 401 to move up and down to adapt to the height adjustment during the installation of the explosion-proof door; the sliding bracket 402 connects the vertical bracket 401 and the base 1 through a hinge and a guide rail, sharing the vertical bearing force of the bracket and improving the overall bearing capacity of the mechanism.

[0035] Lifting mechanism 3: Lifting mechanism 3 includes a separate hydraulic jack 301 and a mobile load-bearing frame 302. Separate hydraulic jack 301 is a commercially available device. The separate hydraulic jack 301 used in this embodiment has a maximum load capacity of 10 tons and a maximum stroke of 150 mm. Manual and electric pumps can also be used depending on the working environment to meet the requirements of explosion-resistant door installation. The mobile load-bearing frame 302 is entirely welded from high-strength steel and is connected to the separate hydraulic jack 301 via M12 bolts and welded to the vertical bracket 401.

[0036] Explosion-proof door fixing device 5: The explosion-proof door fixing device 5 includes six L-shaped mounting plates welded on the vertical bracket 401. The mounting plates and the explosion-proof door are fixedly connected by bolts, which can realize the rapid installation of explosion-proof doors of different weights within the maximum load-bearing capacity.

[0037] During installation work,

[0038] 1. When moving the mounting frame, push the main frame to make the universal wheels 101 at the bottom roll on the ground to move the mounting frame. After reaching the installation location, step on the brake device to fix the position of the mounting frame.

[0039] 2. Place the explosion-proof door on the support adjustment mechanism of the mounting frame, and use bolts to make the L-shaped mounting plate in close contact with the explosion-proof door to ensure the stability of the explosion-proof door.

[0040] 3. Start the lifting mechanism 3 and lift the explosion-proof door to the installation height through the separate hydraulic jack 301. Then, fine-tune the horizontal position of the universal wheel 101 to accurately install it in the predetermined position.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
