Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically relating to a scaffold loading, unloading and transport device. Background Technology

[0002] Utility model patent CN218858456U discloses a transportation device for erecting and dismantling exterior wall scaffolding, including a conveyor frame with four casters, a push handle, an mounting plate, a braking assembly, and a support assembly. This utility model, through the support assembly, facilitates adjustment of the conveyor frame's support range for the exterior wall scaffolding, effectively avoiding the problems of poor transportation stability and easy falling during scaffolding transportation due to its long length and the conveyor frame only supporting one side, thus ensuring transportation efficiency. The braking assembly enables automated emergency braking, avoiding the need for significant force to brake the device in case of emergencies during transportation, as the scaffolding being transported on the conveyor frame is heavy, thus enhancing the safety of scaffolding transportation.

[0003] However, the above-mentioned mechanism has the following problems: Since the support component relies on sliding adjustment of the position of the U-shaped bearing seat on the conveyor frame to achieve extended support for the scaffolding, the overall length of the support component will not exceed twice the length of the conveyor frame, and the effect of extended support for the scaffolding is limited; in addition, since both the conveyor frame and the U-shaped bearing seat are U-shaped structures, it is not convenient for personnel to load and unload the scaffolding. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a scaffold loading and unloading transport device that solves the problems that existing scaffold loading and unloading transport devices cannot support and transport long scaffold steel pipes on both sides, and are inconvenient for loading and unloading scaffolds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scaffold loading and unloading transport device, comprising a front end and a rear end, wherein the front end and the rear end are respectively connected to the two ends of a connecting frame, the connecting frame comprising a connecting rod one and a connecting rod two, the middle ends of the connecting rod one and the connecting rod two being rotatably connected by a pin, and the beginning and end ends of the connecting rod one and the connecting rod two being rotatably connected by a pin, both the front end and the rear end comprising a base plate, the bottom of the base plate being fitted with wheels, the two sides of the base plate being rotatably connected by hinges, a fixing component being provided between the base plate and the side plates, the fixing component comprising a connecting block, the connecting block being fixedly mounted on the base plate, and the connecting block and the side plates having internal threaded holes for threaded connecting bolts.

[0006] The beneficial effects of this utility model are as follows: the connecting rod structure of the connecting frame allows the device to have a large range of length adjustment, so as to effectively support both ends of the scaffolding steel pipe; the side plate can be laid flat to facilitate personnel to load and unload the scaffolding steel pipe on the base plate, and can be erected to stably support the scaffolding steel pipe under the locking of the fixing components.

[0007] To ensure the stability of the connection between the front and rear of the vehicle;

[0008] As a further improvement to the above technical solution: the two ends of the connecting frame are rotatably connected to the side plates in the front and rear of the vehicle via pins.

[0009] The beneficial effects of this improvement are: the setting of two sets of connecting brackets can effectively improve the stability of the connection between the front and rear of the vehicle.

[0010] To ensure the stability of the side panels supporting the scaffold steel pipes;

[0011] As a further improvement to the above technical solution: when the included angle between the side plate and the bottom plate is 90 degrees, the axes of the connecting block and the through holes for connecting bolts on the side plate are collinear.

[0012] The beneficial effect of this improvement is that, with the fixed components locked, the side plate and the bottom plate maintain a stable angle, thereby providing stable support for the scaffolding steel pipes.

[0013] To avoid structural interference between the side plate and the connecting block;

[0014] As a further improvement to the above technical solution: the side plate is provided with a groove structure for sliding connection blocks.

[0015] The beneficial effect of this improvement is that the grooves opened on the side plate can prevent structural interference between the side plate and the connecting block during the rotation of the side plate.

[0016] To effectively ensure the stability of the connector frame during use;

[0017] As a further improvement to the above technical solution: two positioning holes are provided on the side plate, and both positioning holes are arranged around the pin at one end of the connecting frame. A through hole is provided on the connecting rod, which is opposite to the two positioning holes, and a locking bolt is fitted into the through hole. The locking bolt is threadedly connected to the positioning hole.

[0018] The beneficial effect of this improvement is that when the connecting bracket is rotated to the longest or shortest telescopic length, the locking bolts can be inserted into the two positioning holes respectively to securely lock the length of the connecting bracket.

[0019] To save effort in moving this device;

[0020] As a further improvement to the above technical solution: a pusher is installed on the bottom plate in the front of the vehicle.

[0021] The beneficial effect of this improvement is that operators can easily pull the device by pushing it with a push handle.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Example 1:

[0030] like Figure 1As shown in Figure 4: A scaffolding loading and unloading transport device includes a front end 1 and a rear end 2. The front end 1 and the rear end 2 are respectively connected to both ends of a connecting frame 3. The connecting frame 3 includes a first connecting rod 31 and a second connecting rod 32. The middle ends of the first connecting rod 31 and the second connecting rod 32 are rotatably connected by a pin, and the first and last ends of the first connecting rod 31 and the second connecting rod 32 are rotatably connected by a pin. Both the front end 1 and the rear end 2 include a base plate 5. Wheels 7 are installed at the bottom of the base plate 5. Side plates 6 are rotatably connected to both sides of the base plate 5 by hinges 8. The base plate 5 and the side plates 6 are connected to each other. A fixing component 9 is provided between the scaffolding and the side plate 6. The fixing component 9 includes a connecting block 91, which is fixed to the base plate 5. The connecting block 91 and the side plate 6 are provided with internal threaded holes for threaded connecting bolts 92. The connecting rod structure of the connecting frame 3 allows the device to have a large range of length adjustment to effectively support both ends of the scaffolding steel pipes. The side plate 6 can be laid flat to facilitate the loading and unloading of scaffolding steel pipes on the base plate 5, and can be erected to stably support the scaffolding steel pipes when locked by the fixing component 9. The two ends of the connecting frame 3 are rotatably connected to the side plate 6 in the front 1 and the rear 2 of the vehicle via pins. The two sets of connecting brackets 3 can effectively improve the stability of the connection between the front end 1 and the rear end 2. When the included angle between the side plate 6 and the bottom plate 5 is 90 degrees, the axes of the connecting block 91 and the through holes for connecting bolts 92 on the side plate 6 are collinear. Under the locking of the fixing component 9, the side plate 6 and the bottom plate 5 maintain a stable angle, thereby providing stable support for the scaffolding steel pipes. The side plate 6 is provided with a groove structure for sliding connection of the connecting block 91. The groove on the side plate 6 can prevent structural interference between the side plate 6 and the connecting block 91 during the rotation of the side plate 6. Two positioning holes 34 are provided, and both positioning holes 34 are arranged around the pin at one end of the connecting frame 3. The connecting rod 31 has a through hole opposite to the two positioning holes 34, and a locking bolt 33 is fitted into the through hole. The locking bolt 33 is threaded to the positioning hole 34. When the connecting frame 3 is rotated to adjust to the longest or shortest telescopic length, the locking bolt 33 can be inserted into the two positioning holes 34 respectively to securely lock the length of the connecting frame 3. A pusher 4 is installed on the bottom plate 5 in the front 1. The operator can pull the device easily and effortlessly by pushing the pusher 4.

[0031] The working principle of this technical solution is as follows: When the device is idle, the connecting frame 3 is folded to its shortest length, and the bottom plates 5 in the rear 2 and front 1 of the vehicle are close together, maintaining a compact structure for easy storage. When using this device to load and transport scaffolding steel pipes, the locking bolt 33 is removed from one positioning hole 34, and then the connecting frame 3 is stretched to allow the connecting rod 1 31 and connecting rod 2 32 to rotate relative to each other. Then, the locking bolt 33 is inserted into the other positioning hole 34 to lock the connecting rod 1 31. At this time, the connection between the front 1 and rear 2 is closed. The distance is extended and a stable rigid connection is maintained, thereby stably supporting both ends of the scaffolding steel pipe and stably transporting the scaffolding steel pipe; when placing the scaffolding steel pipe on the base plate 5, the included angle between the side plate 6 and the base plate 5 is 180 degrees. After the scaffolding steel pipe is installed, the operator rotates the side plate 6 so that the included angle between the side plate 6 and the base plate 5 is 90 degrees. Then, the bolt 92 is screwed into the connecting block 91 and the internal threaded hole opened on the side plate 6 to lock the angle of the side plate 6, thereby ensuring the stability of the scaffolding steel pipe during transportation.
