Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, and more specifically, to a hydraulic telescopic boom hoisting equipment for transporting building materials with a weight warning function. Background Technology

[0002] Building materials refer to all materials used in the construction industry to construct buildings or structures. These materials include, but are not limited to, cement, steel, wood, bricks, sand, gravel, and various composite materials. In the hydraulic telescopic boom building material hoisting equipment with weight warning function of the present invention, these building materials will be safely and efficiently hoisted to the designated location. The weight warning function of the equipment can ensure that the load-bearing capacity of the equipment will not be exceeded during the hoisting process, thereby ensuring construction safety.

[0003] According to patent document CN112758838A, a building material handling machine is disclosed. Its structure includes: a hydraulic cylinder seat, a winding wheel frame housing, a boom upright, a wheel support plate, a piston hydraulic rod, a boom frame, and a lifting hook seat. This invention achieves a truss-like interlocking balance support effect by using the winding wheel frame housing and the boom upright in conjunction with the wheel buckle column plate at the top of the rope seat wheel frame and the truss winding disc. This significantly improves the efficiency of weight-based operations, effectively preventing swaying of the boom upright and boom frame during the lifting and handling of building materials. It also increases the winding pressure of the anti-tipping wheel disc, effectively stabilizing the material and increasing lifting efficiency, reducing repeated lifting cycles, and achieving a significant increase in weight distribution. The machine's weight balance of building materials is enhanced through wheel pressure, resulting in increased twisting force and stability. This reduces the number of counterweight blocks and increases the stability of the wheel core weight distribution.

[0004] When hoisting building materials, lifting equipment with hydraulic telescopic booms is typically used. These devices can flexibly adapt to different heights and distances through the extension and retraction of the hydraulic telescopic boom. During the hoisting process, the gripper, as a key component, is responsible for firmly holding the building materials such as concrete slabs or steel trusses, ensuring that they are safely and stably hoisted to the designated location. However, traditional hydraulic telescopic boom hoisting equipment has some problems in actual operation. When the weight of the building materials being hoisted is too large, the gripper, while bearing enormous tensile force, will also experience increased frictional wear between itself and the hydraulic boom. In this case, the gripper may loosen due to excessive wear, or even break. Once the gripper malfunctions, the hoisted building materials may become uncontrollable, leading to serious safety accidents that endanger the safety of the workers and the integrity of the equipment. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a hydraulic telescopic boom hoisting device for building materials with a weight warning function. The technical problem to be solved by this invention is that traditional hydraulic telescopic boom hoisting devices have some problems in actual operation. When the weight of the building materials being hoisted is too large, the gripper bears a huge pulling force, and the frictional wear between it and the hydraulic mechanical arm will also increase accordingly. In this case, the gripper may loosen due to excessive wear, or even break. Once the gripper malfunctions, the hoisted building materials may become uncontrollable, thereby causing serious safety accidents and endangering the safety of the operators and the integrity of the equipment.

The upright connecting rod 21735 has two sets of protective upright connecting rods 21735, each with a protective upright 21736 fixedly connected to its outer end. The clamping assembly 22 includes two clamping plate uprights 221, each with an inverted L-shaped clamping plate 222 fixedly connected to its bottom. Each with a retractable upright plate 223 fixedly connected to its top center. The inner top of each retractable upright plate 223 is fixedly connected to the left side of the bidirectional hydraulic push rod 214. At both ends of the right, clamping plate upright plates 221 are fixedly connected to the outer middle of the two clamping plate upright plates 224. The outer walls of the two clamping plate upright plate sliding plates 224 are slidably connected to the inner walls of the two inverted concave guide plates 21717. V-shaped rotating block connecting rods 225 are fixedly connected to the front and rear sides of the two clamping plate upright plate sliding plates 224 near the clamping plate upright plates 221. The outer ends of the two sets of left and right V-shaped rotating block connecting rods 225 are rotatably connected to V-shaped rotating rods. 226, the inner walls of the middle sections of the left and right sets of V-shaped rotating rods 226 are rotatably connected to the outer walls of the left and right sets of columnar connecting rods 21714. The tops of the left and right sets of V-shaped rotating rods 226 are rotatably connected to push-pull uprights 227. The outer walls of the left and right sets of push-pull uprights 227 are slidably connected to the inner walls of the left and right sets of concave guide blocks 21715. The tops of the left and right sets of push-pull uprights 227 are fixedly connected to the front and rear sides of the bottom of the two concave side plates 21733. When hoisting building materials, the hydraulic telescopic boom 1 needs to be activated first. This telescopic boom is responsible for controlling the movement of the material clamping mechanism 2. The material clamping mechanism 2 will move to directly above the building materials to facilitate the next operation. Then, through the action of the bidirectional hydraulic push rod 214, the retractable and expandable upright plate 223 will move inward. As the retractable and expandable upright plate 223 moves inward, the two clamping upright plates 221 and the inverted L-shaped clamping plate 222 at the bottom will also move inward. This series of movements allows the inner sides of the two inverted L-shaped clamping plates 222 to fit tightly against the two sides of the building materials, thereby achieving effective clamping of the materials. As the clamping mechanism begins operation, the two clamping plate uprights 221 move inward, causing the two clamping plate upright slides 224 to slide inward along the inner walls of the two inverted concave guide plates 21717. During the sliding process, through the linkage of the two sets of V-shaped rotating block connecting rods 225, the two sets of V-shaped rotating rods 226 rotate around the columnar connecting rod 21714 as the axis. As a result of the rotation, the two sets of push-pull uprights 227 move downward, thereby pulling the two concave side plates 21733 downward. When the two concave side plates 21733 move downward, they pull the two sets of rotating rods 21727 to rotate through the two columnar connecting rods 21729. The side connecting blocks 21722 at the bottom outer side of the rotating rods 21727 push the two moving base plates 21. 721 moves outward. The outward movement of the base plate 21721 is driven by the action of two columnar push rod connecting blocks 21723 and columnar push rods 21724, pushing two inclined L-shaped rotating rods 21725 to rotate around the concave side plate hinge slots 21734 opened by the two concave side plates 21733 as the axis. This causes the two limiting rods 21726 to move inward and insert into the inner wall of the two reinforcing slots 212 opened by the telescopic arm connecting plate 211. This series of actions finally completes the reinforcement between the reinforcing component 217 and the telescopic arm connecting plate 211, ensuring that the building materials will not bear huge tensile force due to excessive weight during hoisting, thereby avoiding loosening and falling off due to excessive wear, and greatly improving the safety of the hoisting process. At the same time, when the two concave side plates 21733 move downward, they will also drive the two sets of protective upright connecting rods 21735, thereby causing the two sets of protective uprights 21736 to move to the bottom. The downward movement of the protective uprights 21736 is set on both sides of the building material that are not clamped by the two inverted L-shaped clamps 222, further limiting the building material. This measure can effectively prevent the building material from falling off due to the two inverted L-shaped clamps 222 loosening when it is hoisted and placed, thereby further improving the safety of the hoisting process. After the building materials are securely clamped and reinforced, the hydraulic telescopic boom 1 begins operation, lifting and moving the materials to the designated location to complete the lifting task. Throughout the lifting process, the equipment is not only easy to operate but also structurally stable, capable of withstanding significant weight, ensuring both lifting efficiency and safety. Furthermore, the equipment features a weight warning function. Built-in sensors monitor the weight of the lifted building materials in real time. Once the weight exceeds a preset safety threshold, two warning light panels 216 immediately sound an alarm to alert the operator and ensure safe operation. The weight warning function relies on high-precision sensors within the equipment. These sensors capture the weight information of the building materials in real time and convert it into electrical signals, transmitting them to the control unit. The control unit has a preset safety threshold. When the received weight exceeds this threshold, an alarm mechanism is immediately triggered. At this time, the two warning light panels 216 quickly illuminate, emitting a conspicuous warning light to attract the operator's attention. Simultaneously, the control unit may also send more intuitive alarm information to the operator via audible alarms or wireless signals, ensuring a rapid response and appropriate action.

[0022] The working principle of this invention is as follows: When it is necessary to hoist building materials, the first step is to start the hydraulic telescopic arm 1 and control the material clamping mechanism 2 to move directly above the building materials. Then, the bidirectional hydraulic push rod 214 pushes the retractable and expanding upright plate 223 to move inward. The two retractable and expanding upright plates 223 move inward, which in turn drives the two clamping plate upright plates 221 and their bottom inverted L-shaped clamping plates 222 to move inward, so that the inner sides of the two inverted L-shaped clamping plates 222 fit against the two sides of the material, thereby clamping the material. When the two clamping plate upright plates 221 move inward, they drive the two clamping plate upright plate sliding plates 224 to slide inward on the inner walls of the two inverted concave guide plates 21717, and then through the two sets of V-shaped rotating blocks... The connecting rod 225 drives two sets of V-shaped rotating rods 226 to rotate around the columnar connecting rod 21714, pulling two sets of push-pull uprights 227 downwards. The downward movement of the two sets of push-pull uprights 227 pulls two concave side plates 21733 downwards. As the two concave side plates 21733 move downwards, they pull the two sets of rotating rods 21727 to rotate via two columnar connecting rods 21729. This rotation causes the side connecting blocks 21722 at the bottom outer sides of the two sets of rotating rods 21727 to push the two movable base plates 21721 outwards. The outward movement of the two movable base plates 21721, through the two columnar push rod connecting blocks 21723 and the columnar push rods 21724... 724 pushes two inclined L-shaped rotating rods 21725 to rotate around the concave side plate hinge slots 21734 opened in the two concave side plates 21733 as the axis, causing the two limiting rods 21726 to move inward and insert into the inner wall of the two reinforcing slots 212 opened in the telescopic arm connecting plate 211, thereby completing the reinforcement between the reinforcing component 217 and the telescopic arm connecting plate 211. This prevents the equipment from being subjected to huge tensile forces due to excessive weight of building materials during hoisting, and avoids loosening and falling off due to excessive wear. This ensures the safety of the hoisting process. At the same time, the weight warning function of the equipment is activated. The built-in sensor monitors the weight of the hoisted building materials in real time. When the weight exceeds the preset value, the warning function will be activated. When the safety threshold is reached, the two warning light panels 216 will immediately sound an alarm. In addition, when the two concave side plates 21733 move downward, they drive the two sets of protective upright connecting rods 21735, causing the two sets of protective uprights 21736 to move to the bottom. After the two sets of protective uprights 21736 move to the bottom, they are set on both sides of the building material that are not clamped by the two inverted L-shaped clamps 222, further limiting the building material and preventing the two inverted L-shaped clamps 222 from loosening and falling off due to tilting during hoisting and placement, thus further improving the safety of the hoisting process. After the building material is stably clamped and reinforced, the hydraulic telescopic arm 1 starts to operate, lifting the building material and moving it to the designated position.
