Description

Technical Field

[0001] This utility model relates to the field of explosion-proof door technology, and in particular to an explosion-proof door handling device. Background Technology

[0002] In the industrial production sector, explosion-proof doors are crucial equipment for ensuring production safety, and their handling after molding is of paramount importance. Currently, the industry commonly uses traditional forklifts or gantry frame structures to handle the molded explosion-proof doors. However, this method has significant drawbacks: Firstly, traditional handling equipment is complex and bulky, occupying a large amount of production workshop space, resulting in low factory space utilization and increased site usage costs for enterprises. Secondly, in actual operation, its work efficiency is low; the entire process from positioning, grabbing, to placing the explosion-proof door is time-consuming, making it difficult to meet the needs of large-scale production. Furthermore, the operation often requires the cooperation of multiple operators, with cumbersome steps that are prone to errors and demand high levels of professional skills from operators, increasing labor and training costs.

[0003] More importantly, for large SMC molded explosion-proof door products, the demolding process is a critical point for stress release and a potential risk point. When transported by forklift, the explosion-proof door is prone to uneven stress after demolding, which leads to uneven release of internal stress generated during the pressing process. The product may crack or deform directly, resulting in product scrap. The internal stress accumulated during the pressing process and the uneven force during demolding are the main reasons for product cracking, deformation, surface damage and even scrap.

[0004] Therefore, an explosion-proof door handling device is proposed to solve the problems existing in the prior art. Utility Model Content

Simultaneously, the coordinated operation of various mechanisms, through the adjustment of the operating distance and height using components such as the throttle handle, reduces operational complexity, eliminates the need for multiple personnel, lowers the skill requirements for operators, and solves the problem of inconvenient operation. Furthermore, the use of synchronously telescopic forks and mutually cooperating support components effectively balances stress release, preventing the production of defective products. To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: According to one aspect of the present invention, an explosion-proof door handling device is provided, including a fixed support, a spacing adjustment mechanism, a telescopic fork, a height adjustment mechanism, and a support member.

A threaded seat is provided on the side wall of the adjusting screw near the telescopic fork. The threaded seat is sleeved on the adjusting screw, and the adjusting screw and the threaded seat cooperate with each other. A throttle is provided on the end of the adjusting screw near the threaded seat.

[0007] Preferably, the height adjustment mechanism includes two mounting seats disposed on the telescopic fork, each mounting seat being provided with a trapezoidal lead screw, and each trapezoidal lead screw being provided with a T-nut and a fixing nut, and a support member being provided between the T-nut and the fixing nut on the two trapezoidal lead screws.

[0008] Preferably, the support includes a load-bearing frame, which is a square frame.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0016] Please see Figures 1 to 5 This utility model provides an explosion-proof door handling device, the technical solution of which is as follows: The device includes a fixed support 1, a spacing adjustment mechanism 3, a telescopic fork 2, a height adjustment mechanism 4, and a support member 5. A forming unit is provided on one side of the fixed support 1. Two fixed supports 1 are arranged opposite each other, and each fixed support 1 is provided with a movable bracket 6. Each fixed support 1 is provided with a spacing adjustment mechanism 3, and each movable bracket 6 is set on a corresponding spacing adjustment mechanism 3. Multiple columns 7 are evenly distributed on each movable bracket 6, and the top of the multiple columns 7 is provided with a telescopic fork 2. Each telescopic fork 2 is provided with a height adjustment mechanism 4, and the height adjustment mechanism 4 is provided with a support member 5.

[0017] The retractable forklift is equipped with an external control console, commonly used in industrial automation control scenarios. It integrates interactive components such as a touch screen and control buttons, allowing for program setting, status monitoring, and command issuance for various equipment (such as production lines and electromechanical equipment), achieving automated operation and precise control. The control section adopts a servo control system with human-machine interface operation, combined with wireless remote control. The operator's operation efficiency is high, and one person can complete the material handling operation. During the material handling process, the field of vision is convenient for observation, effectively avoiding blind spots and accurately identifying interference positions to make corresponding operations. The control unit of the console can be operated as a separate module or expanded to connect with the data of a fully automated production line for fully automatic control.

[0018] After the formed explosion-proof door is ejected from the forming unit, both sides of the telescopic fork 2 extend simultaneously. The telescopic fork 2 has a maximum load of 3 tons and strong compatibility. By changing the tooling, it can meet the handling operations of products with various shapes. The support 5 is moved to both sides of the explosion-proof door. Technicians can control the extension and retraction of the telescopic fork 2 through the control console to ensure that the telescopic fork 2 can stably move the support 5 to both sides of the explosion-proof door. After the support frames on both sides receive the explosion-proof door, the forming unit detaches from the explosion-proof door. The telescopic fork 2 is then moved in the opposite direction to move the explosion-proof door away from the forming unit, completing the handling. With the cooperation of the telescopic forks 2 and the height adjustment mechanism 4, the explosion-proof door can be quickly and accurately positioned and grabbed, simplifying the handling process, reducing operation time, and improving handling efficiency. At the same time, the various mechanisms work together, and the operation distance and height can be adjusted through components such as the throttle 306, reducing the complexity of operation, eliminating the need for multiple people to work together, reducing the skill requirements of personnel, solving the problem of inconvenience in operation, and also reducing labor costs and the probability of error. In addition, the use of synchronously telescopic forks 2 and mutually cooperating support components 5 can effectively balance stress release and avoid the occurrence of scrap. All drive components are made of high-strength and high-toughness materials, with a compact structure to ensure stable operation under load.

[0019] The spacing adjustment mechanism 3 includes guide rails 301 symmetrically arranged on the left and right sides of the fixed support 1, and each guide rail 301 is provided with multiple sliding blocks 302. The multiple sliding blocks 302 are connected to a movable bracket 6. The fixed support 1 is symmetrically provided with two bearing seats 303 on the front and rear sides, and an adjusting screw 304 is provided between the two bearing seats 303. The adjusting screw 304 is provided with a threaded seat 305 on the side wall near the telescopic fork 2. The threaded seat 305 is sleeved on the adjusting screw 304, and the adjusting screw 304 and the threaded seat 305 cooperate with each other. The adjusting screw 304 is provided with a throttle 306 on the end near the threaded seat 305.

[0020] The guide rail 301 and the sliding block 302 work together to allow the moving bracket 6 to slide stably. Combined with the adjustment functions of the adjusting screw 304 and the threaded seat 305, the spacing of the moving bracket 6 can be flexibly changed. It can adapt to explosion-proof doors of different specifications, eliminating the need to replace large equipment due to door size, reducing the space occupied by equipment, and improving the flexibility of workshop layout. The adjusting screw 304 is driven by the throttle 306, which, together with the threaded seat 305, drives the moving bracket 6 to adjust the spacing. The operation is simple and intuitive, without complicated procedures. Workers can quickly complete the spacing adaptation, shorten the preparation time, and improve the overall efficiency of handling.

[0021] The height adjustment mechanism 4 includes two mounting seats 401 mounted on the telescopic fork 2. Each mounting seat 401 is provided with a trapezoidal lead screw 402, and each trapezoidal lead screw 402 is provided with a T-nut 403 and a fixing nut 404. A support member 5 is provided between the T-nut 403 and the fixing nut 404 on the two trapezoidal lead screws 402.

[0022] Two mounting bases 401 are symmetrically arranged to provide stable support for the trapezoidal screw 402; the fixing nut 404 can lock the position of the T-nut to prevent the support component 5 from shifting in height due to vibration during transportation, ensuring the stability of the explosion-proof door support, improving transportation reliability, and avoiding operational errors caused by structural instability; the trapezoidal screw 402 has high transmission precision, and together with the T-nut 403, rotating the screw can drive the support component 5 to rise and fall stably, which can quickly and accurately adjust the height of the support component 5 to adapt to the transportation needs of explosion-proof doors of different heights, improving the efficiency of height adaptation in the transportation process; the height adjustment is achieved through simple screw rotation operation, without the need for complex tooling or multiple people to cooperate, reducing the difficulty of operation for workers, improving the problem of inconvenience in operation, and ordinary workers can get started after simple training, reducing labor costs and the probability of operational errors.

[0023] The support member 5 includes a load-bearing frame 501, which is a square frame. Two fixing rings 502 are symmetrically arranged on the side of the load-bearing frame 501 near the trapezoidal lead screw 402, and the fixing rings 502 are located between the corresponding T-nuts 403 and fixing nuts 404. Two load-bearing rods 503 are symmetrically arranged at the lower end of the load-bearing frame 501, and each load-bearing rod 503 has a horizontally arranged load-bearing plate 504 at the top. Soft rubber pads are installed at the contact points between the load-bearing plate 504 and the product to prevent damage to the product during the handling process.

[0024] The square frame load-bearing frame 501 has high structural strength and can effectively distribute the weight of the explosion-proof door. The symmetrically arranged load-bearing rods 503 and horizontal load-bearing plates 504 increase the contact area with the explosion-proof door, making the force more even, preventing the explosion-proof door from deforming or slipping during transportation, ensuring transportation stability, and solving the problem of transportation errors and efficiency impact caused by unreasonable structure of existing equipment.

[0025] Each of the aforementioned load-bearing frames 501 has an extension plate 8 at its lower end near the molding unit, and each extension plate 8 is rotatably equipped with a guide wheel 9. The extension plate 8 and the guide wheel 9 serve to guide and support the transition when the load-bearing frame 501 comes into contact with the explosion-proof door. The guide wheel 9 can rotate flexibly in the direction of movement towards the explosion-proof door, reducing the frictional resistance between the explosion-proof door and the handling system, allowing the explosion-proof door to be transferred more smoothly from the mold to the load-bearing frame 501, effectively shortening the handling time and improving the overall handling efficiency. There is no need for operators to precisely control the docking of the explosion-proof door and the load-bearing frame 501; the guide wheel 9 will automatically guide the explosion-proof door to land smoothly on the load-bearing frame 501, reducing the requirements for the operator's skill and accuracy and simplifying the operation process.

[0026] Each of the telescopic forks 2 is equipped with two height adjustment mechanisms 4, and the two height adjustment mechanisms 4 are arranged horizontally in sequence.

[0027] Each telescopic fork 2 is equipped with two laterally arranged height adjustment mechanisms 4, forming a double-support structure. This structure can more evenly distribute the weight of the explosion-proof door, preventing fork deformation or door tilting due to single-point stress. Compared to a single height adjustment mechanism 4, this design greatly improves the load-bearing stability of the explosion-proof door, reduces safety hazards caused by structural instability during handling, and solves the problems of low efficiency and inconvenient operation caused by unreasonable load-bearing structure in existing equipment. Two height adjustment mechanisms 4 can be adjusted individually or in tandem to achieve fine-tuning of the height of the support member 5 on the telescopic fork 2. When handling explosion-proof doors of different specifications and shapes, the support member 5 can be more precisely aligned with the explosion-proof door, ensuring that the explosion-proof door is in a horizontal state. This prevents shaking or slippage caused by inconsistent heights during handling, improves the accuracy and safety of handling, and compensates for the shortcomings of existing equipment in terms of efficiency due to inaccurate adjustment. Furthermore, two load-bearing frames 501 are symmetrically provided on each side of the telescopic fork 2. When in contact with the explosion-proof door, they are located at the four corners of the explosion-proof door and contact the door as synchronously as possible. This effectively balances stress release and avoids cracking or deformation caused by uneven stress release, thereby improving the product qualification rate.

[0028] The fixed support 1 has four lifting plates 10 on its side wall, and the four lifting plates 10 are respectively located at the four corners of the fixed support 1. Each lifting plate 10 has a lifting hole 11. With the lifting plates 10 and lifting holes 11 at the four corners of the fixed support 1, the entire handling system can be quickly lifted, moved and accurately installed in the designated location in the workshop using lifting equipment such as cranes and hoists. Compared with the complicated installation process of traditional equipment, the installation operation is greatly simplified, reducing the installation difficulty and time cost. When it is not needed to be moved, it can be lifted away, improving the flexibility of equipment installation and layout, and improving the problem of inflexible use of workshop space caused by the inconvenience of existing equipment installation.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
