The anti-falling upright post capable of stretching up and down through the power mechanism is fastened on the bottom plate with the wheels, the upper end of the anti-falling upright post is fastened with a suspension, an anti-falling device is arranged on the suspension through a rope chuck, a lifting plate vertical rod capable of stretching up and down through the power mechanism is fastened on the bottom plate, and a lifting plate is arranged at the upper end of the lifting plate vertical rod through a compression spring; and a manual screw rod capable of enabling the bottom plate to be tightly pressed on the ground is further arranged on the bottom plate. When the anti-falling upright post is used, the device is slowly moved, the lifting plate enters the lower part of the side plate of the boxcar, the lifting plate upright post is lifted, the lifting plate is tightly propped against the bottom of the side plate of the boxcar, and the anti-falling upright post is lifted to the required height through the power mechanism. The loading and unloading personnel tie the safety belt to the waist. The device is used as a balance weight by means of the weight of the loaded and unloaded truck, the equipment is relatively light and flexible, the transportation and the movement are convenient, the structure is simple, the cost is low, and the operation is reliable and the use is convenient.

Description

Movable safety protection equipment for truck loading and unloading personnel

Technical Field

The invention belongs to the technical field of loading and unloading machinery, and particularly relates to safety protection equipment for truck loading and unloading personnel.

Background

When the goods with small specific gravity are loaded and unloaded by the truck at a higher position by manpower, the risk of falling accidents of loading and unloading personnel is higher, and the personal safety is difficult to ensure.

Chinese patent application No. CN 10269885A discloses a safety protection device for outdoor loading and unloading personnel, which is structurally characterized in that a steel upright post is fixed on an infrastructure, a support is arranged on the steel upright post, and a safety rope cargo truck loading and unloading operation is installed on a support cross beam through a rope chuck.

Disclosure of Invention

The invention aims to provide a movable safety protection device for truck loading and unloading personnel, so as to avoid personnel falling accidents.

The equipment is light and movable, and the key point is to solve the problem of counterweight. The applicant adopts a unique and ingenious structural design, so that the device can be used as a counterweight by means of the weight of a loaded or unloaded truck.

The structure of the device of the invention is as follows:

an anti-falling upright post capable of vertically stretching through a power mechanism is fastened on a bottom plate with wheels, the upper end of the anti-falling upright post is fastened with a suspension, an anti-falling device and an anti-falling device are arranged on the suspension through rope clamps, the anti-falling device and the lifting plate upright post capable of vertically stretching through the power mechanism are fastened on the bottom plate, and a lifting plate is arranged at the upper end of the lifting plate upright post through a compression spring;

and a manual screw rod capable of enabling the bottom plate to be tightly pressed on the ground is further arranged on the bottom plate. The upright post extends up and down through a power mechanism, and the structure of the upright post is known to mechanical professionals. Safety catch and

the working principle and the use of the device of the invention are as follows: and slowly moving the equipment to enable the lifting plate to enter the lower part of the side plate of the boxcar. And lifting the lifting plate upright rod to enable the lifting plate to tightly push against the bottom of the side plate of the boxcar. Because the spring is contracted to the limit, when the weight of the unloaded vehicle is reduced and the compartment side plate is lifted, the lifting plate can still be kept to be tightly pressed against the bottom of the wagon compartment side plate. And the bottom plate is pressed against the ground by a manual screw rod. The anti-falling upright post is lifted to the required height through the power mechanism. The loading and unloading personnel tie the safety belt to the waist. When in loading and unloading operation, if the loading and unloading operator normally moves, the safety rope of the safety catch can be automatically pulled out or tightened along with the distance, so that the loading and unloading operation is not influenced; if the personnel fall, the safety rope can be quickly pulled out, and the falling protector automatically locks the safety rope to prevent accidents.

The invention has the beneficial effects that: the weight of the loaded and unloaded truck is used as a balance weight, the equipment is relatively light and flexible, the transportation and the movement are convenient, the structure is simple, the cost is low, and the operation is reliable and the use is convenient.

Drawings

Fig. 1 is a schematic front view of the embodiment.

Detailed Description

See the embodiment of fig. 1; the anti-falling upright post 1 is made of multi-section overlapped high-strength section steel. The overlapped high-strength section steel can be stretched to 6.5 meters at most from the height of 3.3 meters when overlapped through the direct-current hydraulic pump, the hydraulic rod and the chain through end-to-end connection in sequence. The bottom plate 2 is provided with four wheels (only two of the falling protector uprights 1 can be seen on the front view structural diagram, the upper end of the falling protector upright 1 is fixedly provided with a suspension 3, four falling protectors 4 are arranged on the suspension 3 through rope chucks (only one of the falling protector uprights 3 can be seen on the front view structural diagram, a hydraulic lifting plate upright 5 is fixedly arranged on the bottom plate 2, a lifting plate 6 is arranged at the upper end of the lifting plate upright 5 through a compression spring clamp 7, the lifting plate 6 is also hinged with the falling protector uprights 1 through a hinge shaft 8, so that the lifting plate 6 is more convenient to be propped against the bottom of a side plate of a wagon compartment, two manual screw rods 9 capable of enabling the bottom plate 2 to be tightly pressed on the ground are arranged on the bottom plate 2 (only one of the accumulator jar, the hydraulic pump and the control box can be seen on the front view structural diagram, 10 represents an accumulator jar, the hydraulic pump and the control box, 11 represents a handle for enabling equipment to move, and 12 represents a manual operating rod of the hydraulic lifting plate upright 5.

The above embodiments are merely for further illustration of the present invention, and the scope of the invention is not limited by the examples.

Claims
