DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following are specific embodiments of the present invention and in conjunction with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0024] A modular construction hoist door pocket structure, as Figures 1 to 4 shown, includes a door pocket main body 1. An accommodation cavity 2 is arranged inside the door pocket main body 1. A rotary drive source 3, a transmission shaft 4, two oppositely arranged sprockets 5, two oppositely arranged chains 6 and two oppositely arranged counterweights 7 are arranged in the accommodation cavity 2. The two sprockets 5, the two chains 6 and the two counterweights 7 are respectively oppositely arranged on both sides of the door pocket main body 1.

[0025] The doorframe main body 1 includes an upper cover 17, two oppositely arranged columns 18 and a lower bottom 19. The lower surface of the upper cover 17 abuts against the upper end faces of the two columns 18. When connecting, the upper cover 17 is supported by the columns 18 to ensure the relative stability of the two. The two ends of the upper cover 17 are respectively connected to one end of the two columns 18. Preferably, the ends of the upper cover 17 and the ends of the two columns 18 are connected by welding. The two ends of the lower bottom 19 are respectively connected to the other ends of the columns 18, and the ends of the lower bottom 19 and the ends of the columns 18 are connected by welding. The upper cover 17 and the lower bottom 19 are both arranged horizontally, and the two columns 18 are arranged vertically. It should be noted that the upper cover 17 and the two columns 18 are both hollow, and the three cooperate to form a receiving cavity 2.

[0026] It should be further noted that the modular design of the doorframe structure makes the installation and disassembly more convenient. Moreover, since the doorframe main body 1 is formed by connecting the upper cover 17, the two columns 18 and the lower bottom 19 to each other, the lengths of the upper cover 17, the columns 18 and the lower bottom 19 can be adjusted according to actual needs, and then the size of the doorframe main body 1 can be adjusted, making the applicable range wider.

[0027] The output end of the rotary drive source 3 is connected to the transmission shaft 4. The rotary drive source 3 uses a reduction motor. The two ends of the transmission shaft 4 are respectively connected to two sprockets 5. The two sprockets 5 are respectively engaged with two chains 6. One ends of the two chains 6 are respectively connected to two counterweights 7, and the other ends of the two chains 6 are both connected to the door main body (not shown in the figure).

[0028] It should be noted that the rotary drive source 3, the transmission shaft 4, the two sprockets 5, the two chains 6 and the two counterweights 7 are all arranged in the receiving cavity 2. The doorframe main body 1 can protect each component, reduce the influence of the harsh construction environment on each component, reduce the failure rate, and can make the overall structure more compact and occupy less space. It should be further noted that the outer surface of the doorframe is flat, so the installation and disassembly are more convenient.

[0029] Two protective cover plates 8 are arranged in the receiving cavity 2. The two protective cover plates 8 respectively cover the outer sides of the two sprockets 5. By covering the protective cover plates 8 on the outer sides of the sprockets 5, the sprockets 5 can be protected to avoid the influence of the external environment on the sprockets 5.

[0030] Two avoidance holes 9 for the transmission shaft 4 to pass through are opened on the two protective cover plates 8, and the transmission shaft 4 passes through the avoidance holes 9 and is connected to the sprocket 5.

[0031] Two parallel guide rails 10 are arranged in the receiving cavity 2. The guide rails 10 are arranged vertically to guide the door main body.

[0032] There are two light curtain seats 11 for installing the light curtain in the accommodation cavity 2. The light curtain seats 11 are used for installing the light curtain, and both of the two light curtain seats 11 are arranged along the length direction of the guide rail 10.

[0033] An installation seat 12 is arranged in the accommodation cavity 2. The rotary drive source 3 is installed on the installation seat 12. A positioning projection one 13 is arranged on the installation seat 12. A positioning hole one 14 adapted to the positioning projection one 13 is formed on the door frame main body 1. The positioning projection one 13 is arranged in the positioning hole one 14. A positioning projection two 15 is arranged on the installation seat 12. A positioning hole two 16 adapted to the positioning projection two 15 is formed on the door frame main body 1. The positioning projection two 15 is arranged in the positioning hole two 16. By the cooperation of the positioning projection one 13 and the positioning hole one 14 and the cooperation of the positioning projection two 15 and the positioning hole two 16, the positioning of the installation seat 12 can be effectively realized, and further the positioning of the rotary drive source 3 can be realized, ensuring the stability of the installation seat 12 and the rotary drive source 3.

[0034] The installation seat 12 extends vertically to form the positioning projection one 13, and the installation seat 12 extends longitudinally to form the positioning projection two 15. The positioning projection one 13 and the positioning projection two 15 are relatively perpendicular, and the positioning projection one 13 and the positioning projection two 15 form a 90-degree angle in space, so as to realize the precise positioning of the installation seat 12 in two directions and further ensure the stability of the installation seat 12 and the rotary drive source 3.

[0035] The specific embodiments described in this text are only examples to illustrate the spirit of the present invention; those skilled in the technical field to which the present invention belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
