Description

Technical Field

[0001] The utility model relates to the technical field of safety protection facilities, in particular to a mobile safety rope mooring device. Background Art

[0002] China has been a major grain producer since ancient times. Grain has always been the foundation of our survival and development, and the cornerstone of national stability and people's well-being. With the advancement of mechanization, grain harvesting has gradually been replaced by machines. Grain harvested by large-scale harvesting equipment such as harvesters is then transported to grain depots, drying stations, and other locations via specialized grain trucks, where it is unloaded.

[0003] Work at height, performed at a height of 2 meters or more above a falling surface where there is a risk of falling, is considered high-altitude work and requires appropriate protective measures, such as wearing a hard hat and securing a safety harness. Grain trucks are typically 4.1 meters high and have a 6-cubic-meter capacity, so unloading personnel must take appropriate safety measures.

[0004] A gantry is commonly used for grain unloading. Traditional gantry unloading has limited working angles and is very troublesome to adjust. Therefore, a dynamic safety rope mooring device is proposed to make the working angle wider and reduce the trouble of going up and down multiple times. Summary of the Invention

[0005] In order to solve the above technical problems, the utility model provides a mobile safety rope tie-down device with a multi-angle working range.

[0006] The technical solution is as follows: A mobile safety rope mooring device includes a counterweight base, characterized in that: a rotating disk is provided on the counterweight base, a retractable sleeve is fixed on the upper part of the rotating disk, a hinge bolt hole and a locking bolt hole are sequentially opened at the top of the sleeve, a slide rail beam is vertically provided on the top of the sleeve, the slide rail beam and the sleeve are hinged by passing a hinge bolt through the hinge bolt hole, and the locking bolt is passed through the locking bolt hole for fixing, a pulley is provided in the slide rail beam, and a lifting ring is provided at the lower end of the pulley, and a safety rope is put on the lifting ring. With the above structure, the working angle can be adjusted by the rotating disk to make the working angle wider, the sleeve can be retracted, and the slide rail beam can be rotated. When in use, the sleeve is raised, the slide rail beam is fixed, and the safety rope is put on. The worker can then pulley into the grain transport vehicle to unload the grain, ensuring the worker's safety. When not in use, the pulley can be stored to save storage space.

[0007] Preferably, the casing comprises an upper casing and a lower casing, the diameter of the upper casing being smaller than that of the lower casing. A travel hydraulic cylinder is connected to the outer side of the casing via a mounting block. The cylinder body of the travel hydraulic cylinder is connected to the lower middle portion of the lower casing, and the piston rod of the travel hydraulic cylinder is connected to the upper end of the upper casing. With this structure, the upper casing can be automatically retracted into the lower casing by the action of the travel hydraulic cylinder, saving space and reducing labor consumption.

With the above structure, the hydraulic pump can be securely provided in the lower casing.

[0009] As a preferred embodiment, the hydraulic pump is connected to the cylinder body of the travel hydraulic cylinder. With the above structure, power can be provided for the extension and contraction of the travel hydraulic cylinder, so that the upper casing can be raised under the drive of the travel hydraulic cylinder, saving manpower.

[0010] Preferably, the slide rail crossbeam is connected to the sleeve via an integral connecting block, the connecting block being wider than the slide rail crossbeam. A slide rail crossbeam end cap is provided at the other end of the slide rail crossbeam, and two pulley movement grooves are symmetrically provided within the slide rail crossbeam, within which the pulley can move. With the above structure, a dedicated pulley movement groove is provided within the slide rail crossbeam, ensuring that the pulley can move smoothly within the pulley movement groove. The slide rail crossbeam end cap provided at the end prevents the pulley from sliding out of the slide rail crossbeam, causing injury or death to workers.

[0011] Preferably, a steel platform parallel to the ground is provided at the connection between the upper casing and the lower casing, and the steel platform extends outward to the outside of the casing;

[0012] A short support rod extends from the other side of the steel platform, and a long support rod extends from the lower end of the hydraulic pump. An inclined ladder is installed between the short and long support rods. With this structure, workers can climb the ladder to the steel platform and independently operate the rope at the steel platform for safety protection.

[0013] Preferably, one side of the rotating disk is connected to the bottom end of the lower casing and the other side is connected to the counterweight base. A rotation locking lever is also provided within the rotating disk, extending longitudinally through the rotating disk and into the counterweight base. With this structure, the rotating disk can be steered and easily adjusted, allowing workers to work at a wider range of angles. The rotation locking lever can lock the rotating disk after determining the angle, preventing it from rotating while the worker is working and causing unexpected situations.

[0014] Preferably, a fixed tube is disposed within the counterweight base, within which is disposed a telescopic rod capable of extending outward or retracting inward. An internally threaded sleeve is vertically disposed at one end of the telescopic rod.

[0017] Compared with the existing technology, the beneficial effects of the utility model are: it can realize multi-angle working surfaces under the premise of ensuring safety, which can enable workers to have a wider working angle. At the same time, the telescopic sleeve and the hydraulic pump cooperate with each other to realize overall lifting, with a maximum lifting height of 6m. The ladder replaces the traditional stairs, which can meet the requirements of construction workers to get on and off the car. It is more flexible and realizes multiple uses of one machine. The telescopic and articulated structure can be folded up when not working, which greatly saves storage space. BRIEF DESCRIPTION OF THE DRAWINGS
