[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:
[0025] like Figs. 1 to 4 As shown in the figure, this utility model embodiment discloses an automatic adjustment counterweight balance glass hanger, including a support beam 1, a suction cup frame 2, a counterweight mechanism 3, and a hanger 4. The suction cup frame 2 is installed at the front end of the support beam 1, and the hanger 4 is installed between the suction cup frame 2 and the counterweight mechanism 3. The counterweight mechanism 3 is provided with a counterweight drive component 31, a first counterweight component 32, and a second counterweight component 33. The first counterweight component 32 and the second counterweight component 33 are symmetrically mounted on both sides of the support beam 1. The first counterweight component 32 and the second counterweight component 33 are connected by a pulley 5. The pulley 5 rolls along the length direction of the support beam 1. A transmission gear is installed on the output shaft of the counterweight drive component 31. A linear rack is assembled on one side of the support beam 1 along the length direction. The transmission gear meshes with the linear rack.
[0026] The counterweight drive unit 31 serves as the power source, with a transmission gear mounted on its output shaft that meshes tightly with a linear rack mounted along the length of one side of the balance beam. When the counterweight drive unit 31 starts operating, it drives the transmission gear to rotate. Due to the meshing relationship between the transmission gear and the linear rack, the rotational motion of the transmission gear is converted into linear motion, which in turn propels the first counterweight assembly 32 and the second counterweight assembly 33 connected to it to move smoothly along the length of the balance beam. These two counterweight assemblies are symmetrically mounted on both sides of the balance beam, and their synchronous movement can flexibly change the counterweight distribution according to actual lifting requirements, thereby achieving a movable counterweight. During the lifting of glass, regardless of how the weight distribution of the glass changes, the counterweight mechanism 3 can automatically adjust the counterweight, quickly and accurately maintaining the balance of the lifting device. This effectively solves the problem of balance adjustment in traditional lifting devices and greatly improves the safety and stability of lifting operations.
[0027] The first counterweight assembly 32 and the second counterweight assembly 33 are connected by the pulley 5, and the pulley 5 rolls along the length direction of the support beam 1. The rolling connection of the pulley 5 reduces the friction when the counterweight assembly moves, so that the first counterweight assembly 32 and the second counterweight assembly 33 can move easily and smoothly on the support beam 1. During the process of lifting the glass, once the imbalance of the lifting appliance is detected, the counterweight assembly can quickly respond and make position adjustment, greatly improving the timeliness and efficiency of the lifting appliance balance adjustment.
[0028] In addition, the pulley 5 rolls along the length direction of the support beam 1, so that the movement path of the counterweight assembly has high flexibility and controllability. When facing different shapes, weights and lifting conditions of the glass, by accurately controlling the rolling of the pulley 5, the counterweight assembly can accurately move to the required position, realize accurate adjustment of the center of gravity of the lifting appliance, and effectively ensure that the lifting appliance can maintain balance in various complex situations, significantly improve the applicability and stability of the lifting appliance. In addition, this connection and movement mode has a relatively simple structure, is easy to maintain and maintain, reduces the maintenance cost and failure rate of the equipment, and further improves the reliability and practicality of the entire lifting appliance system.
[0029] Further, the lower end of the first counterweight assembly 32 is detachably connected with the lower end of the second counterweight assembly 33, and the lower end of the first counterweight assembly 32 and the lower end of the second counterweight assembly 33 are lower than the lower side of the support beam 1. In terms of balance adjustment, the principle of the old scale is used to enhance the balance adjustment ability by using the lever effect, to realize more accurate and efficient balance adjustment and ensure the safety and stability of the glass lifting process.
[0030] From the maintenance and flexibility point of view, the detachable connection greatly facilitates the equipment maintenance and counterweight adjustment. When the counterweight assembly is worn, fails or needs to be replaced by different weight counterweight blocks according to different lifting tasks, the worker can easily separate the first counterweight assembly 32 and the second counterweight assembly 33 for separate maintenance, replacement or adjustment.
[0031] In some embodiments, a diagonal rod 6 is installed between the top of the lifting appliance and the rear end of the support beam 1.
[0032] The first counterweight assembly 32 and the second counterweight assembly 33 are respectively provided with counterweight blocks. In the design of the glass lifting appliance in the embodiment, the inclined rods 6 are connected to the top of the lifting appliance and the rear end of the support beam 1 in an inclined manner. This unique connection method ingeniously builds a stable triangular structure. In the principle of mechanics, a triangle has very high stability. The inclined rods 6 can effectively disperse various stresses generated during lifting, including the tension from the weight of the glass itself, wind force during lifting, and other external force interference. No matter what complex lifting working condition the lifting appliance is in, the inclined rods 6 can greatly enhance the connection strength between the lifting beam and the support beam 1, ensure that the entire lifting appliance structure is not easy to deform or displace when bearing external force, and thus always maintain good overall rigidity.
[0033] In some embodiments, a sliding groove is formed in one side of the support beam 1 along the length direction, the linear rack is provided with a first rack and a second rack, the first rack is installed on the upper side wall of the sliding groove, and the second rack is installed on the lower side wall of the sliding groove. The first rack and the second rack are installed on the upper and lower side walls of the sliding groove, respectively, which has the following advantages.
[0034] Stable and precise transmission: The design of the double racks makes the transmission more stable and reliable, allowing the transmission gears to have double driving force, avoiding slipping and jamming, and making the counterweight assembly move more smoothly and accurately, so that the counterweight can be adjusted in time to maintain the balance of the lifting appliance.
[0035] Strong adaptability: By adjusting the meshing mode of the transmission gears and the double racks, different transmission ratios can be achieved to meet the diversified needs of lifting different weights of glass. When lifting lighter glass, a lower transmission ratio can be selected to make the counterweight assembly move faster and improve work efficiency. When lifting heavier glass, a higher transmission ratio can be selected to increase the driving force and ensure that the counterweight assembly can move smoothly to the appropriate position.
[0036] Guiding and protection: The sliding groove provides a mounting basis for the rack and guides the pulley 5, ensuring the linear and stable movement of the counterweight assembly, preventing the rack from being damaged by external impact, and prolonging the service life of the lifting appliance.
[0037] In some embodiments, the pulley 5 is provided with limiting members at both ends, and the lower ends of the limiting members at both ends extend close to the side surface of the support beam 1. Further, the pulley 5 is provided with at least two.
[0038] In the glass lifting appliance design, the limit pieces are arranged at both ends of the pulley 5, and the lower end is close to the side surface of the support beam 1, so as to effectively limit the transverse displacement of the pulley 5, ensure the stable rolling of the pulley 5 on the support beam 1, avoid the deviation and shaking caused by external force interference, ensure the stable movement of the counterweight assembly, and accurately adjust the balance of the lifting appliance. At the same time, the limit piece can prevent the pulley 5 from derailing and causing the counterweight assembly to fall, greatly improve the lifting safety, reduce the abnormal wear of the parts, and prolong the service life of the lifting appliance. The pulley 5 is arranged at least two, the carrying capacity is increased, the weight of the hoisted heavy object can be evenly dispersed, the hoisting of large and heavy glass is met, the movement of the counterweight assembly is more stable, the bumping caused by the unevenness or uneven force of the support beam 1 is reduced, and the balance adjustment precision of the lifting appliance is improved.
[0039] In some embodiments, a fixing groove 101 is arranged on the other side of the support beam 1 along the length direction, and a drag chain 7 is arranged in the fixing groove 101.
[0040] Further, the electric box 8 and the vacuum parts box 9 are arranged on the first counterweight assembly 32 and the second counterweight assembly 33 respectively.
[0041] In the technical scheme of the glass lifting appliance, the fixing groove 101 is arranged on the other side of the support beam 1 along the length direction, and the drag chain 7 is arranged in the fixing groove 101, and the electric box 8 and the vacuum parts box 9 are arranged on the first counterweight assembly 32 and the second counterweight assembly 33 respectively, which brings many significant technical effects.
[0042] Firstly, the arrangement of the drag chain 7 greatly optimizes the wiring management. During the operation of the lifting appliance, various cables, air pipes and other lines need to move synchronously with the movement of the counterweight assembly. The drag chain 7 can orderly accommodate these lines, avoid the entanglement, wear or excessive pulling of the lines during the movement, effectively protect the integrity and safety of the lines, and reduce the equipment downtime and maintenance cost caused by the line failure. At the same time, the orderly wiring is convenient for the workers to check and maintain the lines, and the maintenance efficiency is improved.
[0043] Secondly, the electric box 8 and the vacuum parts box 9 are arranged on the counterweight assembly, which enhances the stability of the equipment operation. The electric box 8 and the vacuum parts box 9 are integrated on the counterweight assembly, so that their positions change synchronously with the adjustment of the counterweight, which effectively balances the overall gravity center of the lifting appliance. During the hoisting process, even if the glass weight is unevenly distributed or is disturbed by the outside, since the electric box 8 and the vacuum parts box 9 work cooperatively with the counterweight assembly, the balance state of the lifting appliance can be better maintained, and the safety and stability of the hoisting process are ensured.
[0044] In addition, the layout also improves the convenience of operation. The electric box 8 and the vacuum parts box 9 are close to the counterweight assembly, so that the operator can operate and monitor the electrical equipment in the electric box 8 and check and replace the parts in the vacuum parts box 9 while adjusting the counterweight. Without going back and forth between different parts of the spreader, the operation time is saved, and the work efficiency is improved.
