[0003] The existing building climbing frames have certain shortcomings when in use: first, the gaps in the climbing frames are large, which cannot directly allow operators to move up and down, and it is not convenient for operators to climb up and down; second, the standing surface of the climbing frame has poor load-bearing capacity and cannot bear weight more efficiently, and the safety buckles are not convenient for operators to move after being fixed. Finally, after the climbing frame is reinforced, it is not convenient for operators to step on it, which makes it inconvenient for operators to step on the middle layer of the climbing frame, and thus makes the climbing frame unable to adapt to different working environments. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a building climbing frame that can be used in different working environments, so as to solve the technical problems in the prior art that the climbing frame station has poor load-bearing capacity, is inconvenient for construction workers to climb up and down, and is difficult to adapt to different working environments.

[0038] Specifically, Figure 1 and Figure 2 As shown, the support frame 1 is a rectangular frame structure, which is used to be fixedly connected to a building. In this embodiment, the length direction of the support frame 1 is defined as the left-right direction, the width direction of the support frame 1 is defined as the front-back direction, and the height direction of the support frame is defined as the up-down direction. The support frame 1 includes four columns and two rectangular frames respectively connected to the top and bottom ends of the four columns, and each rectangular frame is connected to the column through four connecting pipe sleeves 2.

[0039] The connecting mounting frame 3 is a rectangular frame structure, which is the same as the structure of the above-mentioned rectangular frame. It is connected to the inside of the supporting and fixing frame 1 and is located in the middle of the column to separate the supporting and fixing frame 1 into two layers of the same structure. The connecting mounting frame 3 includes two horizontal mounting rods arranged in parallel and spaced apart in the front-to-back direction and two vertical mounting rods arranged in spaced apart in the left-to-right direction. Both ends of each vertical mounting rod are fixed with connecting pipe sleeves connected to the corresponding column, and both ends of each horizontal mounting rod are fixed with connecting pipe sleeves connected to the corresponding column. The ends of the horizontal mounting rods and the vertical mounting rods that are close to each other share a connecting pipe sleeve 2, and each connecting pipe sleeve 2 is coaxially sleeved on the column and fixedly connected to the column.

[0040] like Figure 1As shown, the ladder includes a ladder frame 5 extending in the vertical direction and a plurality of ladder rods 6 connected to the ladder frame 5 and arranged at intervals in the vertical direction. The ladder frame 5 is connected to two rectangular frames and the connecting mounting frame 3 through six ladder mounting blocks 4, and the ladder frame 5 is arranged at the front side of the supporting fixing frame 1. Two groups of extension pedal structures 7 are provided and both are fixed at the front side of the connecting mounting frame 3, and the two groups of extension pedal structures 7 are symmetrical about the ladder frame 5. Figure 1 and Figure 6 As shown, the extended pedal structure 7 includes a fixed mounting sleeve 8, a torsion spring 9, a pedal support frame 11 and a rotating pedal 10. The fixed mounting sleeve 8 is coaxially sleeved on the horizontal mounting rod at the front side and can rotate relative to the horizontal mounting rod. The torsion spring 9 is installed in the fixed mounting sleeve 8. The rotating pedal 10 is fixedly connected to the fixed mounting sleeve 8 so as to rotate with the fixed mounting sleeve 8. The pedal support frame 11 includes a U-shaped frame relatively fixed to the connecting mounting frame 3 and parallel to the ladder rod 6 and a limiting sleeve 30 fixed at both ends of the U-shaped frame. The limiting sleeves 30 at both ends of the U-shaped frame are coaxially fixed with the horizontal mounting rod at the front side and the two limiting sleeves 30 are respectively located at the axial left and right ends of the fixed mounting sleeve 8 to stop and limit the fixed mounting sleeve in the left and right directions. The rotating pedal 10 can rotate relative to the connecting mounting frame 3 to a position erected on the pedal support frame 11, and can be stepped on by construction workers at this time. When the construction workers step on and leave, the rotating pedal 10 is erected again under the rotation of the torsion spring 9.

[0041] like Figure 2 and Figure 4 As shown, the double-layer pedal structure 19 includes a pedal fixing claw 20, a pedal frame 21, a pedal net 22 and a reinforcing spring rope 23. The pedal frame 21 is located in the connecting mounting frame 3, and the left and right ends of the pedal frame 21 are respectively fixed with three pedal fixing claws 20 arranged at intervals in the front-back direction, and each pedal fixing claw 20 is buckled on the corresponding longitudinal mounting rod on the connecting mounting frame 3 from top to bottom. In this embodiment, the cross-section of the pedal fixing claw 20 in the up-down direction is an inverted U-shape, the diameter of the inverted U-shaped opening of the pedal fixing claw 20 is the same as the diameter of the longitudinal mounting rod, and the depth of the inverted U-shaped opening of the pedal fixing claw 20 is greater than the diameter of the longitudinal mounting rod. The pedal net 22 is a double-layer structure with an upper mesh and a lower mesh, and the space between the upper mesh and the lower mesh is filled with a reinforcing spring rope 23. While reducing the weight, the load-bearing effect is increased by reinforcing the spring rope, thereby improving the load-bearing capacity of the climbing frame.

[0042] There are two groups of safety hook structures 12, which are respectively arranged on the left and right sides of the connecting mounting frame 3 and fixedly connected to the corresponding longitudinal mounting rods of the connecting mounting frame 3. Figure 3As shown, the safety buckle structure 12 includes a lifting collar 14, a fixing collar 13 connected between the lifting collar 14 and the corresponding longitudinal mounting rod, a safety rod 15 that passes through the lifting collar 14 so as to be movable up and down, a positioning baffle 18 fixed on the safety rod 15 and located at the upper and lower sides of the axial direction of the lifting collar 14, a support spring 17 sleeved on the safety rod 15 and respectively located between the corresponding positioning baffle 18 and the end of the lifting collar 14, and a safety hanging ring 16 connected to the upper and lower ends of the safety rod 15 for cooperating with the safety buckle hanging buckle. The axis of the lifting collar 14 is perpendicular to the axis of the fixing collar 13. When the construction personnel climb the ladder or move on the step net, they can fix the safety buckle on the safety belt with the corresponding safety hanging ring 16. When the construction personnel move or crawl, they will pull the safety rod 15 up and down to adapt to the construction environment of the construction personnel.

[0043] A reinforcement stepping structure 24 is provided between the side of the support fixing frame 1 facing away from the ladder frame 5 and the connecting mounting frame 3. Figure 5 As shown, in this embodiment, the reinforcement stepping structure 24 includes a mounting frame connecting sleeve 25, a vertical mounting rod 26, a connecting pedal 27, an angled reinforcement rod 28 and a fixing frame connecting sleeve 29. Among them, the axis of the mounting frame connecting sleeve 25 is perpendicular to the axis of the fixing frame connecting sleeve 29. The mounting frame connecting sleeve 25 is provided with two and is respectively connected to the upper and lower ends of the vertical mounting rod 26. The two mounting frame connecting sleeves 25 are respectively used to be sleeved and fixed on the support fixing frame 1 and the horizontal mounting rod on the side facing away from the ladder frame. The vertical mounting rod 26 passes through the connecting pedal 27 and the connecting pedal 27 is fixed at the center of the vertical mounting rod 26. The upper and lower surfaces of the connecting pedal 27 are symmetrically arranged on the radial left and right sides of the vertical mounting rod 26. The two angled reinforcement rods 28 located on the same radial side of the vertical mounting rod 26 are symmetrical up and down. The fixing frame connecting sleeve 29 is correspondingly fixed to the end of the angled reinforcement rod 28 away from the connecting pedal 27, and the fixing frame connecting sleeve 29 is fixedly connected to the support fixing frame 1. A position limiting reinforcing collar 31 is respectively connected to the upper surface and the lower surface of the connecting pedal 27 , and the two position limiting reinforcing collars 31 are coaxially fixed to the vertical mounting rod 26 .

[0044] In this embodiment, two groups of reinforced stepping structures 24 are provided, and are arranged vertically and symmetrically with respect to the horizontal mounting rod on the side facing away from the ladder frame 5 .

[0045] Before using the building climbing frame applicable to different working environments, the supporting and fixing frame 1 is divided into two parts, the lower part of the supporting and fixing frame 1 and the connecting and mounting frame 3 are first built through the connecting pipe sleeve 2, and then the upper part of the supporting and fixing frame 1 is connected to the lower part of the supporting and fixing frame 1 through the connecting pipe sleeve 2 to form the main structure of the climbing frame. Then the supporting and fixing frame 1 is connected to the building by means of steel ropes or screws to fix the climbing frame as a whole; the ladder frame 5 is fixed in front of the supporting and fixing frame 1 and the connecting and mounting frame 3 by the ladder mounting block 4, so that the ladder frame 5 cooperates with the ladder rod 6 to form a ladder structure, and the ladder frame 5 is used for the operator to move up and down when the climbing frame is used. The inner side of the connecting and mounting frame 3 is built with a pedal frame 21 through a pedal fixing claw 20, and the pedal net 22 inside the pedal frame 21 can be used for the operator to stand and step on, and a reinforcing spring rope 23 is arranged inside the pedal net 22, while reducing the weight, the load-bearing effect is increased by reinforcing the spring rope 23, and the load-bearing capacity of the climbing frame is improved. A fixed installation sleeve 8 is installed in front of the connecting mounting frame 3. The rotating pedal 10 outside the fixed installation sleeve 8 is placed on the outside of the pedal support frame 11 after rotation, so as to support and fix the rotating pedal 10, so that the rotating pedal 10 is leveled, and then the operator can step on the top of the rotating pedal 10, which is more convenient for the operator to enter the ladder frame 5. After use, the rotating pedal 10 is driven to stand up again by the rebound of the torsion spring 9. When the operator works in the climbing frame, the safety buckle is connected with the safety hanging ring 16. When the safety rod 15 is pulled, the safety rod 15 pushes the support spring 17 outside the positioning baffle 18 to shrink and then move up and down around the lifting ring 14, driving the safety hanging ring 16 to move up and down, realizing a wider range of mobile installation of the safety buckle, thereby facilitating the safe use of the operator's work. The supporting and fixing frame 1 and the reinforced stepping structure 24 form a reinforced grid between the supporting and fixing frame 1 and the connecting and mounting frame 3, and the operator can step on it through the connecting pedal 27, which is convenient for the stepping work of the middle layer of the climbing frame, so that the climbing frame is suitable for different working environments.

[0046] The building climbing frame of the present invention, which can be applied to different working environments, allows operators to move up and down by setting an extended pedal structure 7 in conjunction with a ladder frame 5 and a ladder rod 6. The extended pedal structure 7 allows operators to step on the top of the rotating pedal 10, which makes it more convenient for operators to enter the ladder frame 5. After use, the rotating pedal 10 is driven to stand up again by the rebound of the torsion spring 9; by setting a double-layer pedal structure 19 and a safety hook structure 12, construction workers can safely stand on the pedal net to carry out construction work; by setting a reinforced pedal structure 24, the structural strength of the entire climbing frame is improved, and at the same time, a fence is formed to ensure the construction safety of construction workers, and the connecting pedal 27 can be stepped on by construction workers to carry out construction work at a higher position of the building, ensuring that construction work on the middle layer of the climbing frame proceeds normally.

[0047] In other embodiments, the pedal frame may also be directly welded and fixed to the connecting mounting frame, and in this case, there is no need to provide a pedal fixing claw.

[0048] In other embodiments, the pedal fixing claw may also be in the form of a hook, in which case the cross-section of the pedal fixing claw in the up-down direction is arc-shaped, and the pedal frame is still hung on the connecting mounting frame through the pedal fixing plate.

[0049] In other embodiments, the ends of the transverse mounting rod and the longitudinal mounting rod that constitute the connecting mounting frame that are close to each other may also be connected to a connecting pipe sleeve respectively.

[0050] In other embodiments, when the structural strength of the supporting and fixing frame and the connecting and mounting frame is sufficient for normal use, the reinforcing stepping structure may not be provided. In this case, a fence may be provided above the connecting and mounting frame and the fixed supporting frame to ensure the safety of the construction workers. In other cases, in order to ensure the construction work requirements of the middle layer of the climbing frame, only the vertical mounting rod and the connecting pedal may be retained for the construction workers to step on.

[0051] In other embodiments, a reinforced stepping structure may be provided only on the upper portion where the mounting frame is connected to the fixed support frame.

[0052] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
