Description

Technical Field

[0001] The utility model relates to the field of hydraulic lifting mechanisms, in particular to a hydraulic lifting mechanism with an anti-falling structure. Background Art

[0002] Hydraulic lift is a kind of lifting equipment, mainly used in aerial work. Hydraulic lift realizes the lifting function through the pressure transmission of hydraulic oil. Its scissor-type mechanical structure makes the lift have higher stability. The wide working platform and higher carrying capacity make the aerial work range larger and suitable for multiple people to work at the same time. When the hydraulic lift is in use, the staff stands on the working platform. In order to avoid the staff from falling and improve the safety of use, a fall prevention device is usually installed on the working platform.

[0003] However, in the prior art, since the anti-fall structure of the hydraulic lifting platform is usually a guardrail of fixed height, these guardrails are used to protect workers from falling. However, the height of these guardrails is fixed and cannot be adjusted according to actual site conditions, which limits its scope of application. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hydraulic lifting mechanism with an anti-falling structure.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a hydraulic lifting mechanism with an anti-fall structure, including a lifting platform, a support plate is provided at the upper end of the lifting platform, the upper end of the support plate is fixedly connected to a support rod, the inner wall of the support rod is provided with a clamping hole, the inner wall of the support rod is provided with a fixing bolt near the clamping hole, an adjusting rod is movably connected inside the support rod, one side of the adjusting rod is fixedly connected to a guardrail, a sliding groove is provided inside the adjusting rod, a slider is slidably connected inside the sliding groove, one side of the slider is fixedly connected to a clamping plate, and a spring is provided on the right side of the clamping plate.

[0006] Preferably, a fixing rod is fixedly connected to the upper edge of the support plate, a sliding rod is fixedly connected to one side of the fixing rod, a slip ring is sleeved on the outside of the sliding rod, a connecting belt is fixedly connected to the outside of the slip ring, and the other end of the connecting belt is fixedly connected to a fixing seat.

[0007] Preferably, a clamping ring is fixedly connected to the front side of the fixing seat, a clamping ring is movably connected inside the clamping ring, a clamping rod is fixedly connected to one side of the clamping ring, a threaded sleeve is fixedly connected to the other end of the clamping rod, a threaded column is provided inside the threaded sleeve, a mounting plate is fixedly connected to the front side of the threaded column, and a strap is fixedly connected to the other side of the mounting plate.

[0008] Preferably, the sliding block slides in the sliding groove through a clamping plate and a spring.

[0009] Preferably, the threaded sleeves are provided in two groups and are symmetrically arranged about the center line of the fixing seat.

[0010] Preferably, the threaded sleeve is movably connected to the fixing seat via a short rod, a clamping ring and a clamping ring.

[0011] By adopting the above technical scheme, by rotating the fixing bolt and pushing the card plate, the card plate compresses the telescopic rod and slides out from the inside of the adjusting hole, releasing the limit on the adjusting rod, pulling the guardrail upward, and the guardrail drives the adjusting rod to slide inside the support rod. When the card plate reaches another set of adjusting holes, under the action of the spring, the card plate enters the adjusting hole to limit the adjusting rod, and the fixing bolt is rotated in the opposite direction. One end of the fixing bolt is close to one side of the adjusting rod to achieve secondary fixation of it, that is, the guardrail is raised. The height of the guardrail can be adjusted by means of components such as the card plate, telescopic rod, spring, and adjusting hole, so as to meet different usage requirements and reduce the limitations of its use.

[0012] By adopting the above technical solution, by rotating the threaded sleeve, the threaded column slides out of the threaded sleeve under the action of its internal thread and the external thread of the threaded column, thereby realizing the separation of the mounting plate and the fixing seat, and the staff can replace the strap. Similarly, during installation, the threaded column is slid into the threaded sleeve and rotated in the opposite direction to complete the installation of the strap. In the process of rotating the threaded sleeve, the retaining ring will rotate inside the retaining ring. With the cooperation of the retaining ring and the retaining ring, the stability of the threaded sleeve during rotation can be increased. The strap can be quickly loaded and unloaded through components such as the threaded sleeve, retaining ring, retaining ring, and threaded column, and can be replaced after long-term use. At the same time, the setting of the strap can restrict the staff to the support plate, thereby further reducing the risk of falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, the threaded sleeve 20 is rotated, and under the action of its internal thread and the external thread of the threaded column 21, the threaded column 21 slides out of the threaded sleeve 20, thereby separating the mounting plate 22 and the fixing seat 16, and the staff can replace the strap 23. Similarly, during installation, the threaded column 21 is slid into the threaded sleeve 20 and rotated in the opposite direction to complete the installation of the strap 23. In the process of rotating the threaded sleeve 20, the retaining ring 18 will rotate inside the retaining ring 17.

At the same time, the setting of the strap 23 can restrict the staff on the support plate 2, thereby further reducing the risk of falling.

[0026] Working principle: When the hydraulic lifting mechanism is in use, first, the height of the guardrail 7 is adjusted according to the use requirements. The specific operation is to rotate the fixing bolt 5 and push the card plate 10. The card plate 10 compresses the telescopic rod and slides out from the inside of the adjusting hole, releases the limit of the adjusting rod 6, pulls the guardrail 7 upward, and the guardrail 7 drives the adjusting rod 6 to slide inside the support rod 3. When the card plate 10 reaches another set of adjusting holes, under the action of the spring 11, the card plate 10 enters the adjusting hole to limit the adjusting rod 6, and rotates the fixing bolt 5 in the opposite direction. One end of the fixing bolt 5 is close to one side of the adjusting rod 6 to achieve secondary fixation of it, that is, the guardrail 7 is raised. The height of the guardrail 7 can be adjusted by the card plate 10, telescopic rod, spring 11, adjusting hole and other components, so as to meet different use requirements and reduce the limitations of its use. When the staff walks onto the support plate 2, the strap 23 is fixed to the outside of his body. Finally, the lifting platform 1 is turned on. The lifting platform 1 pushes the support plate 2 to move up and sends the staff to the working position. When a new tie strap 23 needs to be replaced, the threaded sleeve 20 is rotated. Under the action of its internal thread and the external thread of the threaded column 21, the threaded column 21 slides out of the threaded sleeve 20 to separate the mounting plate 22 and the fixing seat 16, and the staff can replace the tie strap 23. Similarly, during installation, the threaded column 21 is slid into the threaded sleeve 20 and rotated in the opposite direction to complete the installation of the tie strap 23. In the process of rotating the threaded sleeve 20, the clamping ring 18 will rotate inside the clamping ring 17. With the cooperation of the clamping ring 18 and the clamping ring 17, the stability of the threaded sleeve 20 during rotation can be increased. The tie strap 23 can be quickly loaded and unloaded through the threaded sleeve 20, the clamping ring 18, the clamping ring 17, the threaded column 21 and other components, and then it can be replaced after long-term use. At the same time, the setting of the tie strap 23 can restrict the staff on the support plate 2, thereby further reducing the risk of falling.
