Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to an aluminum film climbing frame construction lifting device. Background Art

[0002] The climbing frame is also called the lifting frame. According to its power source, it can be divided into several main categories such as hydraulic, electric, and manual. It is a new type of scaffolding system developed in recent years. It is mainly used in high-rise shear wall buildings. It can climb up or down along the building. This system has completely changed the scaffolding technology: first, there is no need to turn over the frame; second, it eliminates the disassembly and assembly process of the scaffolding (once assembled, it is used until the construction is completed), and is not restricted by the height of the building, which greatly saves manpower and materials. It also has a significant improvement on the traditional scaffolding from a safety perspective and has great development advantages in high-rise buildings.

[0003] In the prior art, the lifting device of the climbing frame is generally lifted and lowered by an electric hoist or a hydraulic rod. This method has the following disadvantages: the structure used by the equipment is complex and the cost is high. At the same time, after lifting, the climbing frame needs to be prevented from falling by a limit device alone. The operation steps are cumbersome, and the dead weight of the climbing frame is increased, resulting in high energy consumption.

[0004] For example, Chinese patent CN210134636U discloses an aluminum film climbing frame construction lifting device, which can realize the climbing and descending of the climbing frame by controlling the engagement of the second gear with the rack plate on the track plate through the drive of a servo motor. In addition, after climbing, the fixing mechanism on the third gear can prevent the climbing frame from falling. The structure is relatively simple, the dead weight is relatively light, and it will not cause excessive energy consumption, thus saving construction cost and operating cost.

[0005] However, the device does not have protective devices during use, which may cause workers on the climbing frame to fall, and the safety is not high.

[0006] For this reason, we urgently need to provide an aluminum film climbing frame construction lifting device. Utility Model Content

[0007] The utility model aims to provide an aluminum film climbing frame construction lifting device to solve the problem of low safety due to the lack of protective devices during use proposed in the above-mentioned background technology, which may cause workers on the climbing frame to fall.

[0012] Preferably, the clamping unit includes a telescopic member and a latching tooth, the telescopic member is fixedly installed on the right side of the inner wall of the climbing frame, and the latching tooth is fixedly installed on the right end of the telescopic member.

[0013] Preferably, the end of the sliding member away from the climbing frame is slidably connected to the front and rear sides of the track plate, and the gear and rack plate are meshed with each other. The motor drives the rotating shaft to rotate, so that the gear rotates and meshes with the rack plate, thereby driving the climbing frame to move up and down along the track plate through the sliding member, thereby realizing the lifting of the climbing frame.

[0014] Preferably, a clamping hole with a diameter equal to that of the insertion rod is opened at the front left of the top of the climbing frame, and the insertion rod is engaged with the clamping hole to close the opening and closing door and the climbing frame, thereby preventing workers from falling during construction.

[0015] Preferably, the bottom of the compression spring is fixedly connected to the top of the disc, and the compression spring squeezes the mounting plate to provide a downward thrust for the insertion rod, thereby making the insertion rod and the clamping hole opened in the climbing frame cooperate more stably.

[0016] Preferably, a storage box is installed inside the climbing frame, and the tools required for construction are stored in the storage box, which is convenient for workers to store and retrieve tools during construction, thereby improving construction efficiency.

[0018] 1. The aluminum film climbing frame construction lifting device is provided with a protective unit. When the staff enters the climbing frame, they pull the plug rod upwards and push the opening and closing door and the climbing frame to close. When the plug rod is located directly above the clamping hole opened in the climbing frame, the plug rod is released. Under the action of the compression spring, the disc is squeezed downward to drive the plug rod to move down and engage with the clamping hole, thereby fixing the opening and closing door to prevent the staff from falling and improve the safety of the staff during construction. This solves the problem of lack of protective devices during use in the background technology, which causes the staff on the climbing frame to fall and the safety is not high.

[0019] 2. The aluminum film climbing frame construction lifting device is equipped with a shock-absorbing unit. When the climbing frame contacts the ground, the damping rod and the buffer spring cooperate to prevent the climbing frame from colliding with the ground, causing a large shake of the climbing frame and causing the workers to fall.
