Description

Technical Field

[0001] The invention relates to the technical field of fire engineering equipment, and in particular to a hydraulic lifter for a fire pipeline. Background Art

[0002] Fire pipe lift refers to a device specially used for installing, repairing and maintaining fire pipe systems in high-rise buildings. It combines the characteristics of lifts and fire systems, and can quickly and safely transport fire pipes and related equipment inside the building to ensure the normal operation and maintenance of the fire protection system of the entire building. In terms of background technology, fire pipe lifts usually use advanced electrical control systems and automation technologies to improve operational efficiency and safety; There are still the following defects in specific use: 1. If the road surface is uneven or bumpy during transportation, the pipeline is prone to shake left and right due to vibration, causing it to tilt. This will cause the pipeline to fall off or collide with other objects, causing safety accidents. At the same time, the left and right tilting of the pipeline will affect the balance and stability of the entire elevator, increase the instability factors during equipment operation, affect the operator's work safety, and long-term left and right tilted transportation will cause damage to the pipeline itself, such as bending, deformation or uneven force at the connection, reducing the service life and safety of the pipeline.

The tilted pipe requires construction workers to spend extra time and energy to adjust and repair it, affecting the construction progress and efficiency.

[0022] The complete working principle and steps of the above embodiment are as follows: Initial qualification: 1. Equipment preparation and initial positioning Equipment placement: First, move the hydraulic lift body 1 to the area where the work is required, and ensure that the base is firmly in contact with the ground. The movement of the hydraulic lift body 1 is usually achieved through universal wheels or casters at the bottom, which is convenient for flexible adjustment in different positions.

[0023] Stabilizing device: After moving to the appropriate position, lock the casters or support rods of the base to prevent the equipment from shifting or tilting during lifting and lowering to ensure its stability.

[0024] Initial inspection: Check the hydraulic system, power supply and various components of the hydraulic lift body 1 to ensure that the hydraulic cylinder, clamping device and guide rail 13 are in normal condition for safe operation.

[0025] 2. Loading of target objects Place objects: Place heavy objects such as fire fighting pipes on the lifting cabin 11. The lifting cabin 11 is the core load-bearing component of the entire hydraulic lifter body 1, which is responsible for carrying and lifting objects.

[0026] Clamping and fixing: After the object is placed on the lifting cabin 11, the object is fixed by the clamping ring 12 and the clamping plate 14. The clamping ring 12 is a ring structure that can wrap the object and apply appropriate clamping force, while the clamping plate 14 can provide greater lateral support to prevent the object from tilting or shaking during the lifting process. The clamping ring 12 and the clamping plate 14 are used together to ensure that the object remains stable during the entire lifting process.

[0027] 3. Hydraulic system starting and lifting Hydraulic system activation: The operator starts the hydraulic system, and the lift cabin 11 begins to lift upward. The hydraulic system controls the height of the lift cabin 11 through hydraulic cylinders, and can provide a stable and uniform lifting force.

[0028] Guide rails 13 guide: During the lifting process, guide rails 13 play a key guiding role. Guide rails 13 are located on both sides of the lift cabin 11, providing a fixed path for vertical movement, so that the lift cabin 11 can rise smoothly along the set track under the action of hydraulic pressure. The existence of guide rails 13 effectively prevents the lateral deviation or tilt of the lift cabin 11, ensuring the verticality of the heavy object during the lifting process.

[0029] Slow-speed adjustment: The hydraulic system is usually equipped with a slow-speed control function. When approaching the target height, the hydraulic lift body 1 will automatically slow down the rising speed so that the operator can align the installation position more accurately.

[0030] 4. Precise positioning and fine-tuning Height fine-tuning: When the lift 11 approaches the target height, the operator can use the fine-tuning function of the hydraulic system to make detailed height adjustments. Through fine-tuning, the lift 11 can be gradually adjusted to the preset height, which is especially important for tasks that require precise installation.

[0031] Horizontal adjustment: The clamping ring 12 and the clamping plate 14 also have left-right fine-tuning functions, allowing the operator to ensure that the object is aligned with other components or structures, thereby achieving more precise horizontal positioning. Using these fine-tuning functions, the entire device can ensure that the position of the lifted heavy object in space is completely in line with the design requirements.

[0032] 5. Fixing and installation of objects Fastening objects: Once the object has reached its intended location, the operator can secure it to the supporting structure using bolts, brackets, or other fixings to ensure that it will not move during subsequent operations.

[0033] Clamp Loosening: When the object is fixed in place, the operator can loosen the clamping ring 12 and the clamping plate 14 to allow them to gently release the object. At this time, the lifting cabin 11 remains in place to ensure that the object has been firmly and securely fixed.

[0034] 6. Safe pressure relief and equipment reset Gradual pressure relief: When the object has been fixed and the hydraulic lift body 1 no longer needs to provide support, the operator can gradually release the pressure of the hydraulic system to slowly lower the lift cabin 11 to avoid impact on the hydraulic cylinder or guide rail 13.

[0035] Equipment reset: After the lift cabin 11 returns to the initial position, the various components of the hydraulic lift body 1 return to the standby state so as to carry out the next round of operation or move to other areas for continued use.

[0036] Equipment cleaning: Check whether the equipment has any parts that are damaged or deformed during operation, and perform necessary cleaning and maintenance on the equipment.

[0037] 7. Review and Overall Inspection Safety check: Check the stability of installed objects to confirm that they are firmly connected and not tilted to ensure safety.

[0038] Equipment maintenance: The hydraulic lifter body 1 needs regular maintenance after use. Check the amount of hydraulic oil, the lubrication of the guide rail 13, and the degree of wear of the clamping ring 12 and the clamping plate 14 to extend the service life of the equipment.

[0039] When using: The steps of the balance resetting mechanism 2 for ensuring that the pipeline placed on the hydraulic lifter body 1 remains balanced are as follows: like Figure 3 As shown, when the operator pushes the clamping upright plate 14 to move inside the guide rail 13, since the two clamping upright plates 14 are fixedly installed with the slide plate body 25 inside, and the slide plate body 25 is slidably connected with the tooth plate 26 inside, and the tooth plate 26 and the toothed wheel 24 are meshed with each other, the clamping upright plate 14 will drive the slide plate body 25 to move during the movement, so the movement of the slide plate body 25 will also drive the toothed plate 26 to move, and the obstacle rod 29 fixedly connected to the lower end of the toothed plate 26 will move synchronously, so that the toothed wheel 24 meshed with the toothed plate 26 will move together, so the movement of the toothed wheel 24 will pull the telescopic rod 22 out, and then as shown in FIG. Figure 4As shown, the outer walls of the two tooth plates 26 are respectively fixedly mounted with a first clamping block 27 and a second clamping block 28. Therefore, when the clamping plate 14 is moved to fit the outer wall of the fire-fighting pipe, if the fire-fighting pipe is skewed on one side of the second clamping block 28, and the length of the second clamping block 28 is greater than the first clamping block 27, when the operator pushes the clamping plate 14, the second clamping block 28 will first touch the fire-fighting pipe, and the second clamping block 28 will first push the fire-fighting pipe to be straightened. Secondly, in the process of the second clamping block 28 pushing the fire-fighting pipe, one of the tooth plates 26 fixedly mounted on the outer wall of the second clamping block 28 will be pushed into the The inside of one slide plate 25 moves toward the side close to the telescopic rod 22, and the toothed wheel 24 meshing with the toothed plate 26 rotates at the same time, so the other toothed plate 26 fixedly installed on the outer wall of the first clamping block 27 moves inside the other slide plate 25 toward the side away from the telescopic rod 22 until the first clamping block 27 touches the outer wall of the fire pipe. In this way, the movement of the clamping vertical plate 14 drives the first clamping block 27 and the second clamping block 28 to contact the outer wall of the fire pipe first, and the fire pipe is balanced by the first clamping block 27 and the second clamping block 28 touching the outer wall of the fire pipe to prevent the fire pipe from tilting. Tilt buffer mechanism for providing buffering effect when one end of the pipeline is tilted 3 steps: like Figure 5 As shown, when the movement of the slide plate 25 drives the tooth plate 26 and the obstacle rod 29 fixedly connected to the lower end of the tooth plate 26 to move synchronously to abut against the outer wall of the bottom end of the balance plate 33, if the initial placement of the fire pipe does not allow both ends of the fire pipe to be placed in the arc grooves opened in the balance plate 33, and the center of the fire pipe is not at the midpoint of the balance plate 33, and the problem of one end of the fire pipe being longer than the other end occurs, as the hydraulic lifter body 1 is raised and lowered, when the fire pipe tilts to the left, the fire pipe tilts to the left. The tilted fire pipe will press down the balance plate 33, so that the swing rod 32 deflects to the left, and then the swing rod 32 deflected to the left will push the rotating rod 35 to deflect downward, so that the rotating rod 35 after deflection will contact the outer wall of the first obstacle column 37, and the deflection to the left of the swing rod 32 will cause the spring 39 fixedly installed on the outer wall of the third obstacle column 310 to stretch toward one side of the second obstacle column 38, and then the concave-convex surface set at the top of the obstacle rod 29 will push the balance plate 33 tilted to the left to reset the lifting support and deflect to the right; Similarly, when the fire-fighting pipe tilts to the right, the fire-fighting pipe tilting to the right will press down the balance plate 33, thereby causing the swing rod 32 to deflect to the right. Secondly, the swing rod 32 deflecting to the right will push the rotating rod 35 to deflect downward. The rotating rod 35 after deflection will also contact the outer wall of the first obstacle column 37. In addition, the rightward deflection of the swing rod 32 will cause the spring 39 fixedly installed on the outer wall of the third obstacle column 310 to stretch toward the other side of the second obstacle column 38. Therefore, the concave-convex surface set at the top of the obstacle rod 29 will push the balance plate 33 tilted to the right to lift and support and reset to the left. In summary, when the fire-fighting pipe tilts, the deflection of the rotating rod 35 will stretch the spring 39, and the concave-convex surface set at the top of the obstacle rod 29 will squeeze the balance plate 33, thereby playing a buffering and resetting role for the tilted fire-fighting pipe. The anti-wear coating mechanism used to form a lubricating oil film on the pipe surface to provide sufficient friction force has four steps: like Figures 7 and 8 As shown, when the swing rod 32 deflects, the helical gear 41 fixedly connected to the outer wall of one side of the swing rod 32 will rotate, so the rotation of the helical gear 41 will drive the rotating gear 42 meshing therewith to rotate, and the rotation of the rotating gear 42 will also drive the gear plate 43 meshing therewith to rotate, so the inclined rod 45 rotatably connected to the outer wall of one side of the gear plate 43 will rotate in a circular trajectory, and the arc plate 46 fixedly connected to the end of the inclined rod 45 away from the gear plate 43 will rotate with the rotation of the inclined rod 45, thereby the upper support rod 47 fixedly connected to the outer wall of the top end of the arc plate 46 As the arc plate 46 rotates, it will be pushed to swing in the vertical direction, so that the oil spray port 48 fixedly connected to the inner wall of the upper push rod 47 will spray lubricating oil on the surface of the fire pipe placed inside the balance plate 33 as the upper push rod 47 swings in the vertical direction. In addition, the rotation of the inclined rod 45 will also drive the slider 410, one end of which passes through the outer wall of the arc plate 46, to slide in the arc groove provided inside the arc plate 46, so that the sliding of the slider 410 causes the friction column 411 fixedly connected to the outer wall of the slider 410 to rub the surface of the fire pipe placed inside the balance plate 33; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
