[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, this embodiment is a new type of chimney platform type steel ladder, comprising:

[0031] The platform steel ladder part includes a steel platform 11, steps 12, connecting columns 13, handrails 14, and a weight-reducing opening 15;

[0032] The steel platform 11 is anchored to the wall, and steps 12 are equidistantly fixed to the lower part of one side of the steel platform 11, a connecting column 13 is fixed at one end of the step 12, and a handrail frame 14 is fixed to the outside of the connecting column 13, and a weight reduction opening 15 is equidistantly opened through the upper part of the steel platform 11;

[0033] The steel platform 11 is the main installation carrier of the steel ladder of the platform. A plurality of steps 12 form a climbing structure for climbing to detect exhaust gas on the upper part of the chimney. The connecting column 13 is used to install and fix the handrail 14. The handrail 14 is used to facilitate construction workers to climb up. The weight reduction opening 15 reduces the weight of the steel platform 11 to save material costs.

[0034] The steel platform 11 is designed to be spiral, and the upper surface of the step 12 is provided with anti-slip patterns at equal intervals;

[0035] The spiral shape not only improves the aesthetics, but also facilitates climbing. The anti-slip pattern increases friction, making it easier for construction workers to climb.

[0036] Working principle: After the steel platform 11 is anchored to the wall, multiple steps 12 are fixed to the lower part of one side of the steel platform 11 in sequence to form a climbing structure, and a handrail frame 14 is installed on one end of the multiple steps 12 through a connecting column 13. When used in conjunction, it can meet the needs of construction workers to climb and detect exhaust gas from the chimney;

[0037] Compared with the previous work of anchoring multiple embedded parts to the wall, this solution saves time and effort, improves the actual use effect, and is convenient to use.

[0038] See also Figure 1-4 As shown, this embodiment is based on the above embodiment 1 and further includes a security part, which includes a guide groove 21, a guide block 22, a security rope 24, and a buckle 25;

[0039] The guide groove 21 is opened at the upper part of one side of the steel platform 11, and the guide block 22 slides in the guide groove 21, the security rope 24 is arranged in the middle of the front of the guide block 22, and the buckle 25 is fixed to one end of the security rope 24;

[0040] A mounting seat 23 is fixed to the middle of the front of the guide block 22, and the other end of the security rope 24 is fixed to the middle of the front of the mounting seat 23;

[0041] The guide groove 21 performs structural sliding installation on the guide block 22 to provide the required position movement, and the guide block 22 performs structural fixing on the mounting seat 23 to fix one end of the security rope 24, and the other end of the security rope 24 is fixed to the buckle 25, and the two are connected with the waist belt of the construction personnel to provide security protection for the construction personnel working at heights;

[0042] It also includes a position limiting part, which includes a torsion spring 31, a movable block 32, and a limiting block 33;

[0043] The torsion springs 31 are symmetrically fixed at the upper and lower ends of the guide groove 21, and the upper and lower ends of the movable block 32 are fixed to the inner side of the opposite set of torsion springs 31, and the limit block 33 is arranged on one side of the movable block 32 in contact with the torsion springs 31.

[0044] The torsion spring 31 is used to install the structure of the movable block 32 and provide the movable block 32 with the ability to restore to its original state after deformation. The movable block 32 can cooperate with the limit block 33 to limit the position of the backward movement while satisfying the forward movement of the guide block 22, so as to meet the security protection requirements of the construction personnel;

[0045] The front part of one side of the limit block 33 is sleeved with a limit column 34, and one end of the limit column 34 is sleeved in the guide groove 21, and the front side of the limit column 34 is in sliding contact with the back side of the guide block 22;

[0046] The limit column 34 fixes the limit block 33 to meet the above requirements, and the sleeve connection method is adopted, so that the guide block 22 can be easily disassembled and moved back to the initial use position;

[0047] Working principle: After one end of the security rope 24 is fixed by the mounting seat 23, a buckle 25 is fixed to the other end of the security rope 24;

[0048] At this time, a pressing force is applied to the movable end of the ring buckle 25, so that the movable end moves inward to expose the opening, and the ring buckle 25 is connected to the waist belt of the human body through the opening. When the construction personnel continue to climb the step 12 to move up, the guide block 22 slides up in the guide groove 21, and applies force to the movable block 32 after contacting it. Under the action of the torsion spring 31, the movable block 32 rotates, so that the guide block 22 moves up smoothly. If the construction personnel accidentally slips and falls, the guide block 22 slides between an adjacent set of limit blocks 33, and after acting on the lower limit block 33, the guide block 22 can be stopped from moving downward due to the resistance force of the limit column 34;

[0049] This solution provides security protection for construction workers, reduces the probability of accidents, and meets usage requirements.
