Technical Field

[0001] The invention relates to the field of building steel structures, in particular to a building canopy bearing frame. Background Art

[0002] A canopy support frame is a structure used to build on the top of a factory building to block rain and sunlight. It is usually made of materials such as metal or plastic, and is durable, waterproof and sun-proof. During the installation process, it is necessary to ensure that the canopy mounting frame is firmly connected to the structure of the factory building to ensure its stability and safety.

[0003] The following defects exist when installing the existing building canopy bearing frame:

[0004] 1. During installation, the load-bearing frames need to be hoisted one by one to the fixed structure of the plant according to the installation gap through lifting equipment, which makes hoisting more difficult;

[0005] 2. When installing and fixing the support frame, welding and bolting are usually used for connection, which increases the difficulty and cost of subsequent maintenance and replacement.

[0006] In view of the above problems, the present invention provides a building canopy bearing frame to solve the above problems. Summary of the invention

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a building canopy bearing frame, comprising: a bearing frame, a first position-limiting bearing slide rail, a second position-limiting bearing slide rail, a connecting shaft, and two driving mechanisms;

[0008] The two driving mechanisms are symmetrically arranged at the two ends of the bearing frame by bolt fixation, and are used to drive the bearing frame to move on the first limit bearing slide rail and the second limit bearing slide rail; the two driving mechanisms are connected by the connecting shaft, and the connecting shaft is used to control the synchronous rotation of the two driving mechanisms;

[0009] The first position-limiting load-bearing slide rail and the second position-limiting load-bearing slide rail are used to bear the load-bearing frame, and the load-bearing frame is used to lay the canopy.

[0010] Further, preferably, the first position-limiting load-bearing slide rail and the second position-limiting load-bearing slide rail have the same structure.

[0011] Further, preferably, the first position-limiting bearing slide rail comprises: an I-beam rail, two position-limiting slideways, and a driving rack;

[0012] The two limit slideways are symmetrically fixed on both sides of the I-beam rail, the driving rack is fixedly arranged in the middle concave channel of the I-beam rail, and the driving rack is meshed with the driving mechanism.

[0013] Further, preferably, the bottom bearing member of the limiting slideway and the I-beam rail form a triangular structure.

[0014] Further, preferably, the driving mechanism comprises: a bearing seat, a driving chamber, a gear, a worm wheel, a worm, and a steel wheel;

[0015] The bearing seat is fixed on the bearing point of the bearing frame, and two groups of steel wheels are symmetrically rotatably arranged on the bearing seat, and the steel wheels are rollingly arranged in the limiting slideway;

[0016] The driving chamber is fixed on the bearing seat, and the worm wheel is rotatably arranged in the driving chamber; the worm is rotatably arranged in the driving chamber and meshes with the worm wheel;

[0017] The gear is coaxially fixed on the output shaft of the worm gear and meshes with the driving rack.

[0018] Further, preferably, a limiting boss is provided at the contact portion between the bearing seat and the limiting slide, and the limiting boss is used to prevent the bearing frame from lateral shaking.

[0019] Further, preferably, one end of the worm is coaxially connected to the connecting shaft, and the other end is detachably provided with a crank, and the crank is rotated to drive the worm.

[0020] Compared with the prior art, the present invention provides a building canopy bearing frame, which has the following beneficial effects:

[0021] 1. The position of the bearing frame on the first limit bearing rail and the second limit bearing rail can be freely adjusted through the driving mechanism, thereby effectively improving the installation efficiency of the canopy bearing frame and reducing the difficulty of the bearing frame installation operation;

[0022] 2. The worm wheel and the worm in the driving mechanism form a physical self-locking when they are in meshing state, thereby preventing the worm wheel from rotating when the worm is not rotating, that is, preventing the load-bearing frame from moving under the action of external force, thereby improving the stability of the load-bearing frame installation;

[0023] 3. When the position of the carrying frame needs to be adjusted, the moving direction of the carrying frame can be changed by changing the rotation mode of the crank, which is simple and efficient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] Reference Figures 1 to 4 The present invention provides a technical solution: a building canopy bearing frame, comprising: a bearing frame 1, a first position-limiting bearing slide rail 2, a second position-limiting bearing slide rail 3, a connecting shaft 4, and two driving mechanisms 5;

[0030] The two driving mechanisms 5 are symmetrically arranged at both ends of the supporting frame 1 by bolt fixing, and are used to drive the supporting frame 1 to move on the first limit bearing slide rail 2 and the second limit bearing slide rail 3; the two driving mechanisms 5 are connected by the connecting shaft 4, and the connecting shaft 4 is used to control the synchronous rotation of the two driving mechanisms 5;

[0031] The first position-limiting bearing slide rail 2 and the second position-limiting bearing slide rail 3 are used to bear the bearing frame 1 , and the bearing frame 1 is used to lay a canopy.

[0032] As a preferred embodiment, the first position-limiting load-bearing slide rail 2 and the second position-limiting load-bearing slide rail 3 have the same structure.

[0033] After the load-bearing frame 1 is assembled and transported to the construction site, the driving mechanism 5 is installed at the load-bearing point of the load-bearing frame 1, and the two driving mechanisms 5 are connected by connecting the rotating shaft 4. After completing the above operations, the first limit load-bearing slide rail 2 and the second limit load-bearing slide rail 3 are fixedly installed at the construction site, and the load-bearing frame 1 is lifted by a crane or other lifting equipment, and the driving mechanism 5 is aligned with the first limit load-bearing slide rail 2 and the second limit load-bearing slide rail 3. After the alignment and connection are completed, the position of the load-bearing frame 1 on the first limit load-bearing slide rail 2 and the second limit load-bearing slide rail 3 can be freely adjusted by the driving mechanism 5, thereby effectively improving the installation efficiency of the load-bearing frame 1 and reducing the difficulty of moving the load-bearing frame 1. At the same time, after the position of the load-bearing frame 1 is determined, the driving mechanism 5 will form a physical self-locking, thereby avoiding subsequent fixed connection operations on the load-bearing frame 1, simplifying the installation steps of the canopy load-bearing frame, and further improving the installation work efficiency while ensuring safety performance.

[0034] As a preferred embodiment, the first position-limiting bearing slide rail 2 comprises: an I-beam rail 21, two position-limiting slideways 22, and a driving rack 23;

[0035] The two limiting slideways 22 are symmetrically fixedly arranged on both sides of the I-beam rail 21 , and the driving rack 23 is fixedly arranged in the middle concave channel of the I-beam rail 21 , and the driving rack 23 is meshed with the driving mechanism 5 .

[0036] As a preferred embodiment, the bottom bearing member of the limiting slide 22 and the I-beam rail 21 form a triangular structure, thereby ensuring the bearing strength of the limiting slide 22 .

[0037] It should be noted that after the driving mechanism 5 is connected to the limiting slide 22, the driving mechanism 5 is operated by external force, so that the driving mechanism 5 moves in the limiting slide 22 through the driving rack 23, that is, the supporting frame 1 moves relative to the I-rail 21, thereby simplifying the difficulty of moving the supporting frame (1) in the form of rolling, reducing the installation burden of the staff and improving the installation efficiency.

[0038] As a preferred embodiment, the driving mechanism 5 includes: a bearing seat 51, a driving chamber 52, a gear 53, a worm wheel 54, a worm 55, and a steel wheel 56;

[0039] The bearing seat 51 is fixed on the bearing point of the bearing frame 1, and two groups of steel wheels 56 are symmetrically arranged on the bearing seat 51, and the steel wheels 56 are rollingly arranged in the limiting slideway 22;

[0040] The driving chamber 52 is fixed on the bearing seat 51, and the worm wheel 54 is rotatably arranged in the driving chamber 52; the worm 55 is rotatably arranged in the driving chamber 52 and meshes with the worm wheel 54;

[0041] The gear 53 is coaxially fixed on the output shaft of the worm gear 54 and meshes with the driving rack 23 .

[0042] As a preferred embodiment, one end of the worm gear 55 is coaxially connected to the connecting shaft 4 , and the other end is detachably provided with a crank 6 , and the crank 6 is rotated to drive the worm gear 55 .

[0043] It needs to be explained that the worm 55 is rotated by turning the crank 6, and the worm 55 drives the worm wheel 54 to rotate during the rotation, and the worm wheel 54 causes the gear 53 to rotate during the rotation process, that is, the gear 53 drives the supporting seat 51 to move relative to the I-beam rail 21 under the action of the driving rack 23, thereby moving the supporting frame 1.

[0044] It should be noted that the worm wheel 54 and the worm 55 form a physical self-locking when they are in meshing state, thereby preventing the worm wheel 54 from rotating when the worm 55 is not rotating, that is, preventing the supporting frame 1 from undergoing relative displacement; the moving direction of the supporting frame 1 can be changed by changing the rotation mode of the crank 6.

[0045] As a preferred embodiment, a limiting boss 7 is provided at the contact portion between the bearing seat 51 and the limiting slideway 22 , and the limiting boss 7 is used to prevent the bearing frame 1 from lateral shaking and improve its stability.

[0046] In specific implementation, when installing the building canopy bearing frame, the bearing frame 1 is lifted by a crane or other lifting equipment, so that the steel wheel 56 rolls into the limiting slide 22, and then the worm 55 is rotated by the crank 6. The worm 55 drives the worm wheel 54 when rotating, so that the gear 53 causes the bearing seat 51 to slide under the action of the driving rack 23, even if the bearing frame 1 moves relative to the I-rail 21.

[0047] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
