Technical Field
[0001] This utility model relates to the field of fall protection equipment technology, and in particular to a fall protection safety belt fastening device for cargo covering operations in truck compartments. Background Technology
[0002] In the process of covering cargo in truck compartments, in order to ensure the safety of workers and prevent them from falling, a fall arrest safety belt fastening device must be used. This device mainly consists of a secure attachment point, attachment point connectors, intermediate connectors, and a full-body safety belt.
[0003] Existing fall arrestor safety belt fastening devices typically use single-point anchoring, requiring operators to frequently unfasten and refasten the safety belt when moving, increasing operational complexity. Furthermore, their height adjustment capability is insufficient and cannot adapt to different vehicle heights. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a safety belt fastening device for covering cargo in truck compartments to prevent falls. It aims to improve the problem of operators frequently unfastening and refastening their safety belts when moving, which increases the complexity of the operation, and the insufficient height adjustment capability, which cannot adapt to different truck compartment heights.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety belt fastening device for preventing falls during cargo covering operations in truck compartments, comprising a base, a support column symmetrically fixedly connected to the top of the base, a support plate fixedly connected to the top of the support column, a hydraulic cylinder fixedly connected to the middle of the support plate, a push rod fixedly connected to the output end of the hydraulic cylinder, a lifting platform fixedly connected to the top of the push rod, rod holes symmetrically opened inside the support plate, a limit rod slidably connected to the rod holes of the support plate, the top of the limit rod fixedly connected to the bottom of the lifting platform, a bracket fixedly connected to the top of the lifting platform, a guardrail fixedly connected to the top of the bracket, and a fall prevention mechanism provided above the guardrail.
[0006] By adopting the above technical solution, when in use, the operator climbs up the ladder and uses the transfer platform to climb to the top of the carriage. The elastic strap is then put around the operator's waist for restraint and fixation. During the covering operation, the operator can move freely on the top of the carriage through the cooperation of the slide rail, slide rod and sliding ring, and is restrained by the elastic strap. The elastic strap can prevent the operator from falling. By activating the hydraulic cylinder and cooperating with the limit rod, the lifting platform and guardrail can be moved up or down stably, thereby enabling flexible adjustment of the working height to meet the needs of working in different carriages.
[0007] Preferably, the fall protection mechanism includes a slide rail, the bottom of which is fixedly connected to the top of the guardrail, a sliding sleeve is slidably connected to the outer wall of the slide rail, and a slide rod is fixedly connected to one side of each of the two sliding sleeves.
[0008] Preferably, a sliding ring is slidably connected to the outer wall of the slide rod, a traction rope is fixedly connected to one side of the sliding ring, and an elastic strap is fixedly connected to one end of the traction rope.
[0009] Preferably, magnets are fixedly connected to both sides of the sliding ring, and the diameter of the sliding ring is larger than the diameter of the sliding rod.
[0010] Preferably, the outer wall of the slide bar is symmetrically fixedly connected with a limiting plate, and the limiting plate is made of iron material.
[0011] Preferably, a transfer platform is fixedly connected to both sides of the guardrail, and a ladder is fixedly connected to both sides of the lifting platform.
[0012] Preferably, the top of the guardrail is symmetrically fixedly connected with baffles, and the two baffles are arranged on both sides of the slide rail.
[0013] Preferably, the base has uniformly spaced mounting holes inside, and the mounting holes of the base are threaded with fixing pins.
[0014] This utility model has the following beneficial effects: 1. In this utility model, during use, the operator climbs up the ladder and reaches the top of the carriage with the help of the transfer platform. The elastic strap is then put around the operator's waist for restraint and fixation. During the covering operation, the operator can move freely on the top of the carriage through the cooperation of the slide rail, slide rod and sliding ring, and is restrained by the elastic strap. The elastic strap can prevent the operator from falling.
[0015] 2. In this utility model, longitudinal free movement is achieved by sliding the sliding sleeve to the sliding rail, and lateral free movement is achieved by sliding the sliding ring to the sliding rod. Through the three-level linkage of the sliding rail, sliding rod and sliding ring, the operator can move freely on the top of the carriage even when restrained. The operator does not need to frequently unfasten the safety belt, and can work at any position on the top of the carriage, which significantly improves work efficiency.
[0016] 3. In this utility model, by using two hydraulic cylinders to work synchronously, and with the cooperation of the limit rod, the lifting platform and guardrail can be moved up or down stably, thereby enabling flexible adjustment of the working height to meet the needs of working in different carriages.
