Description

Technical Field

[0001] The utility model relates to the technical field of elevator shafts, in particular to a top structure of an elevator steel structure shaft. Background Technique

[0002] Generally, important mechanical and electrical elevator equipment such as power traction devices, pulley groups, and electric control devices are installed at the top of the elevator shaft. The existing shaft top does not have the functions of rain protection and heat dissipation, and cannot avoid the rust of the shaft structure and the damage and overheating of the electrical equipment inside the top.

[0003] The Chinese patent discloses a top structure of an elevator shaft (authorization publication number CN220666791U). The setting of the slope-shaped plate in this patented technology facilitates drainage during the rainy season. The support frame arranged in the middle of the slope-shaped plate is used to abut and support the slope-shaped plate, playing a role in stabilizing the overall structure. A certain space is formed between the slope-shaped plate and the top cover plate, which is conducive to air circulation, dissipating heat from the surface of the top cover plate, and thus having a certain heat dissipation effect on the elevator electrical equipment arranged below the top cover plate. The protection plate frame is composed of vertical frame bars and horizontal frame bars. After installing the protection plate, the protection plate has more fixed positions, increasing the structural strength of the protection plate and having a higher wind resistance. Louvers are arranged on the protection plates around, which can increase the internal air circulation and can dissipate heat from the internal elevator electrical equipment better.

[0004] However, it has certain drawbacks: its louvers are used for air circulation. During long-term use, dust and impurities in the air are likely to accumulate on the surface of the louver blades. Over time, the accumulation becomes thicker and thicker, blocking the gaps between adjacent blades, thus affecting air circulation and preventing normal heat dissipation.

Specific implementation manner

[0023] Please refer to Figure 1 , Figure 2 and Figure 6 In an embodiment of the present utility model, a top structure of an elevator steel structure hoistway includes a support cover 1. A support plate 2 is installed at the lower end of the support cover 1, and a protection mechanism 3 is arranged above the support cover 1. The protection mechanism 3 includes a protection top 4. A support block 5 is installed on the lower surface of the protection top 4, and the lower end of the support block 5 is installed at the central position of the upper surface of the support cover 1;

[0024] The entire support plate 2 is welded to the top of the elevator hoistway 19, and the support cover 1 is welded to the support plate 2;

[0025] Double doors are provided on the front surface of the support cover 1 for easy opening;

[0026] The upper surface of the support plate 2 is used to install elevator power equipment, such as traction equipment, electric control equipment, etc.;

[0027] The protection top 4 is used to protect the support cover 1 to prevent rainwater from directly impacting the support cover 1.

[0028] In Figure 1 : A plurality of filter nets 6 are connected through the left and right side surfaces of the support cover 1 from front to back; while the filter nets 6 dissipate heat inside the support cover 1, they prevent dust and impurities from entering the inside of the support cover 1.

[0029] In Figure 1 、 Figures 3 to 5 : At both left and right ends of the upper surface of the support cover 1, adjusting mechanisms 7 are provided. The adjusting mechanism 7 includes a fixed seat 8. The lower end of the fixed seat 8 is installed on the upper surface of the support cover 1. A motor 9 is installed on the rear surface of the fixed seat 8. A cam 10 is installed at the output end of the motor 9. A slider 11 is installed on the front surface of the fixed seat 8. A slide bar 12 is slidably connected through the inside of the slider 11. The upper end of the slide bar 12 is movably attached to the cam 10. A fixed block 13 is installed above the slider 11 on the outside of the slide bar 12. A spring 14 is installed at the center position of the lower surface of the fixed block 13. The spring 14 is located outside the slide bar 12, and the lower end of the spring 14 is connected to the slider 11. Fixed rods 15 are installed at the four corners of the lower surface of the fixed block 13. The fixed rods 15 movably penetrate through the slider 11. A cleaning member 16 is provided at the lower end of the slide bar 12. The cleaning member 16 includes two upper and lower brush plates 17. The lower end of the slide bar 12 is connected to the upper brush plate 17. The brush plate 17 is movably attached to the filter screen 6.

[0031] When the cam 10 rotates, it can continuously squeeze the slide bar 12 downward, thereby driving the upper brush plate 17 to move to the middle of the filter screen 6 and driving the lower brush plate 17 to move to the lower end position of the filter screen 6, so as to comprehensively process the filter screen 6 and avoid the blockage of the filter screen 6;

[0032] The motor 9 is electrically connected to an external control system for automatic start and stop.

[0033] The working principle of the present utility model is as follows: After the staff welds the support plate 2 to the top of the elevator shaft 19, then installs the elevator power equipment, and then welds the support cover 1. When maintenance is required, open the double doors on the front surface of the support cover 1 for maintenance; the two filter screens 6 dissipate heat from the inside of the support cover 1 in real time. Every once in a while, the motor 9 starts to drive the cam 10 to rotate. The cam 10 continuously squeezes the slide bar 12 downward, and the slide bar 12 rises through the spring 14, so as to perform reciprocating up and down movement. The brush plate 17 moves up and down with the slide bar 12 to clean the surface of the filter screen 6, avoiding the blockage of the filter screen 6.
