Description

Technical Field

[0001] The utility model relates to the technical field of building tripods, in particular to a tripod for demolishing buildings. Background Art

[0002] Demolition engineering refers to the demolition of completed or partially completed buildings or structures. It usually includes the demolition of civil buildings, industrial plants, and foundations. In the process of building demolition, scaffolding is needed for auxiliary operations.

[0003] Most of the existing tripods are spliced ​​and fixed by multiple sets of bolts. The setting of multiple sets of bolts requires manual work to constantly align the bolt holes during installation, which results in a low splicing rate of the tripod and is inconvenient for staff to operate and dismantle later. The bolts are very likely to fall off during the disassembly process, which is not convenient for subsequent re-splicing. After the tripod is used, a lot of dust and gravel will stick to the surface of the pedal. Therefore, during the disassembly process, the gravel and dust are very likely to slide as the pedal is removed. The fallen gravel may hit the personnel, equipment or other objects below, causing personal injury or equipment damage. To address this problem, we have proposed a tripod for building demolition.

[0015] Compared with the prior art, the utility model provides a tripod for building demolition, which has the following

[0016] Beneficial effects:

[0017] 1. The tripod for demolishing buildings is provided with a control component. The support block is moved in the groove of the moving block. The support block is moved out from the corner of the L-shaped hole, and the L-shaped hole can release the restriction on the moving block. The moving block is forced to bounce up under the support of spring 2. The L-shaped rod fixed on the surface of the moving block drives the slide bar to slide horizontally in the fixed frame under the support of spring 1. The clamping teeth fixed on the surface of the slide bar slide on the surface of gear 1, and gear 1 can drive the rotating column and the rotating rod to rotate. After the rotation, the clamping block fixed on the surface of the rotating rod coincides with and is parallel to the through hole opened on the surface of the support frame, and the support frame can be separated from the tripod to facilitate the subsequent operation of the operator.

[0018] 2. The tripod for demolishing buildings is provided with a driven component. When the moving block pops up, the moving rod fixed on the surface of the moving block can drive the rack to slide on the surface of the gear two. The gear two is forced to drive the round rod to rotate on the surface of the fixed plate. When the round rod rotates, the disc fixed on the surface of the round rod can rotate synchronously. The rotating disc can continuously knock on the tripod through the knocking rod, and the support frame can be synchronously subjected to the force of the knocking vibration. The dust and gravel remaining on the surface of the pedal can fall from the holes opened on the surface of the pedal, thereby preventing the operator from being accidentally injured by gravel falling when the operator takes the support frame.

The gear 84 is forced to drive the rotating column 83 and the rotating rod 82 to rotate. After the rotation, the clamping block 81 fixed on the surface of the rotating rod 82 coincides with and is parallel to the through hole 3 opened on the surface of the support frame 1, and the support frame 1 can be separated from the tripod 4 to facilitate the subsequent operation of the operator.

[0027] The surface of the support frame 6 is provided with an L-shaped hole 10, and the setting of the L-shaped hole 10 can limit the movement of the moving block 882. The fixing member 88 includes: an L-shaped rod 881, the surface of the L-shaped rod 881 is fixedly connected to the surface of the sliding rod 86, the L-shaped rod 881 penetrates the support frame 6 and is slidably connected to the support frame 6, and when the L-shaped rod 881 moves, the sliding rod 86 can slide synchronously in the fixed frame 5.

The rack 92 is meshed with the second gear 93, and the second gear 93 is penetrated by the round rod 94 and is fixedly connected to the round rod 94. The round rod 94 is rotatably connected to the surface of the fixed plate 7, and the round rod 94 penetrates the disk 95 and is fixedly connected to the disk 95. The surface of the disk 95 is hinged with the knock rod 96, and the surface of the knock rod 96 is fixedly connected to one side of the torsion spring 97, and the other side of the torsion spring 97 is fixedly installed on the surface of the disk 95. When the rack 92 moves, the second gear 93 can drive the round rod 94 to rotate, and the disk 95 fixed on the surface of the round rod 94 rotates synchronously.

[0028] In the present invention, when the support frame 1 and the tripod 4 need to be disassembled and separated, the support block 885 is moved in the L-shaped hole 10, and the support block 885 slides in the groove 884 synchronously. When the support block 885 moves out of the corner of the L-shaped hole 10, the moving block 882 loses its restriction, and the moving block 882 can bounce up under the support of the second spring 883. When the moving block 882 bounces up, the L-shaped rod 881 fixed on the surface of the moving block 882 can drive the slide bar 86 to move horizontally in the fixed frame 5 under the support of the first spring 87, and the surface of the slide bar 86 The fixed card tooth 85 slides on the surface of the gear 1 84, and the gear 1 84 is driven by the force to drive the rotating column 83 and the rotating rod 82 to rotate. After the rotation, the card block 81 fixed on the surface of the rotating rod 82 coincides with and is parallel to the through hole 3 opened on the surface of the support frame 1, so that the support frame 1 can be separated from the tripod 4 to facilitate the subsequent operation of the operator.

When it is necessary to splice the support frame 1 and the tripod 4 again, the through hole 3 opened on the surface of the support frame 1 is passed through the block 81, and the bottom of the support frame 1 and the tripod 4 are connected. The surface of the frame 4 is fitted, and after fitting, the support block 885 is moved, and the support block 885 contacts the groove 884 inside the moving block 882. The moving block 882 moves under the support of the spring 2 883, and the L-shaped rod 881 fixed on the surface of the moving block 882 drives the sliding rod 86 to move. The locking teeth 85 on the surface of the sliding rod 86 slide on the surface of the gear 1 84, and the gear 1 84 can drive the rotating column 83 and the rotating rod 82 to rotate. After the rotation, the block 81 fixed on the surface of the rotating rod 82 can form a staggered shape with the through hole 3, so the splicing of the support frame 1 and the tripod 4 can be completed.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
