Description

Technical Field

[0001] This utility model relates to the field of elevator engineering construction technology, and more specifically, it relates to a material transfer device for elevator engineering construction. Background Technology

[0002] During elevator construction, long, narrow materials such as guide rails often need to be moved. As an important component of elevators, guide rails are long and heavy, and are prone to displacement or even tipping over during transport due to slippage or shaking. This not only damages the materials themselves but also poses safety hazards to the construction site.

[0003] Existing material transfer methods typically involve manual handling or simple transport tools. While these methods can accomplish basic material transfer, they often fail to effectively clamp and secure long, narrow materials like guide rails. Due to a lack of specific design, materials are prone to slipping or colliding on transport vehicles due to vibration or movement, increasing construction safety risks and potentially affecting construction efficiency. To address this issue, developing a material transfer device that can effectively clamp and securely fix guide rails has become an important requirement for improving construction efficiency and safety. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a material transfer device for elevator engineering construction, so as to solve the technical problems mentioned in the background art, which are that effective clamping and fixing cannot be achieved, and that materials are prone to slipping or colliding on the transport vehicle due to vibration or movement due to the lack of targeted design.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a material transfer device for elevator construction, comprising a support frame, a fixing mechanism on the support frame, the fixing mechanism comprising a tray, support rods, mounting frames, push rods, cross members, top rods, clamping plates, and a pressure applying mechanism; two sets of trays are mounted on the bottom of the support frame; multiple sets of support rods are mounted between the two sets of trays; multiple sets of mounting frames are mounted on the two sets of trays; multiple sets of push rods are slidably mounted on both sides of the multiple sets of mounting frames; the cross members are mounted on the top of the multiple sets of push rods; the top rods are mounted on the top surface of the multiple sets of cross members; the clamping plates are mounted on the bottom of the multiple sets of push rods; the pressure applying mechanism comprises a screw, a pressure plate, a knob, and a rotating plate; the screw is rotatably mounted on both sides of the multiple sets of mounting frames; the pressure plate is connected to the outer wall of the multiple sets of screws; the knob is mounted on the top of the multiple sets of screws; and multiple sets of rotating plates are rotatably mounted on both sides of the multiple sets of mounting frames, with their inner sides abutting against the top of the top rods.

[0008] The present invention is further configured such that a return spring is installed on the bottom surface of each of the multiple sets of cross-shaped parts. The return springs are provided in multiple sets and are respectively connected to the outer side of the multiple sets of mounting frames. The setting of the return springs enables the cross-shaped parts to automatically reset after clamping and releasing the guide rail, thereby improving the operating efficiency. At the same time, the connection between the return springs and the outer side of the mounting frame enhances the stability of the reset action and effectively avoids the operation problems caused by incomplete reset.

[0009] The present invention is further configured such that guide rods are installed on both sides of the multiple sets of mounting frames, and the multiple sets of guide rods are slidably connected to the cross component and the guide rods respectively. The setting of the guide rods provides a good guiding effect, ensuring the stability and accuracy of the cross component during the sliding process, thereby avoiding uneven clamping or structural jamming caused by movement deviation. At the same time, the setting of guide rods on both sides of the mounting frame makes the overall structure of the device more stable, improving its service life and reliability.

[0010] The present invention is further provided that soft pads are installed on the inner side of each of the multiple sets of clamping plates. The soft pads can effectively protect the surface of the clamped guide rail from being scratched or damaged by the hard clamping plates, while improving the stability of clamping. The soft pads also have a certain buffering effect, which can absorb some of the vibration and impact during the pressure process, thereby improving the performance and safety of the device.

[0011] The present invention is further provided that the top ends of the multiple sets of top rods are provided with rounded corners. The rounded corner design at the top end can reduce the contact stress between the top rod and the object being clamped, thereby avoiding local scratches or damage during the pressure application process. At the same time, the rounded corner structure can reduce the accidental injury to the operator caused by sharp parts that may occur during operation, thereby improving the safety and humanization of use.

[0012] The present invention is further configured such that each of the multiple sets of rotating plates is provided with a return spring. The return spring is installed on the bottom surface of the multiple sets of rotating plates and connected to the outer wall of the mounting frame. The setting of the return spring enables the rotating plate to quickly return to its original position after completing the clamping or releasing action, thereby shortening the operation time and improving the work efficiency. At the same time, the connection between the return spring and the outer wall of the mounting frame provides good support and stability for the entire return action, avoiding the failure of the clamping function due to incomplete return.

[0013] This utility model is further configured such that a lifting mechanism is provided on the outside of the support frame. The lifting mechanism includes a base frame, a fixed frame, rotating wheels, casters, a transmission column, and a hydraulic cylinder. The base frame is located below the support frame, and the fixed frame is installed on one side of the base frame. Two sets of rotating wheels are provided at one end of the base frame, and two sets of casters are provided on the bottom surface of the fixed frame. The two ends of the transmission column are rotatably connected to the support frame and the fixed frame, respectively. The hydraulic cylinder is rotatably installed on the base frame, and its telescopic end is rotatably connected to the transmission column. The lifting mechanism provides lifting power through the hydraulic cylinder, ensuring that the support frame can be raised and lowered smoothly. The cooperation between the base frame and the fixed frame provides solid support for the entire device. The design of the rotating wheels and casters improves the flexibility and adaptability of the device's movement. The transmission column evenly distributes the power of the hydraulic cylinder to the support frame and the fixed frame, thereby ensuring the smoothness and safety of the entire lifting process.

[0014] The present invention is further configured such that a connecting rod is rotatably installed at the top of the fixed frame. Two sets of connecting rods are provided, and the top of the connecting rods are rotatably connected to both sides of the support frame. The connecting rods provide additional structural support to the support frame, effectively dispersing the force applied to the support frame, thereby avoiding deformation or instability caused by excessive force at a single point. The rotatable installation design of the connecting rods improves the flexibility of the structure, enabling the device to quickly adjust its position under different working conditions, while ensuring the stability and reliability of the overall structure.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a material transfer device for elevator engineering construction, which has the following beneficial effects:

[0017] 1. The fixing mechanism is ingeniously designed. Through the coordinated action of the support plate, support rod, mounting frame, push rod, cross component, top rod, and clamping plate, it can achieve a stable clamping of the guide rail. The inner side of the clamping plate is equipped with a soft pad, which can effectively avoid damage to the surface of the guide rail during clamping. At the same time, the cooperation between the cross component and the return spring allows the device to automatically reset when the clamping force is released, thereby realizing a quick guide rail disassembly operation. This structure not only ensures the safety of the guide rail during transportation, but also improves the convenience of fixing and disassembly, fully meeting the high-efficiency needs of the construction site.

[0018] 2. The pressure mechanism, through the combined design of a screw, pressure plate, knob, and rotating plate, can flexibly control the clamping and releasing process. The rotation of the knob drives the screw to rotate, achieving threaded engagement with the pressure plate, thereby precisely adjusting the clamping force. The cooperation between the rotating plate and the return spring allows the device to quickly return to its initial state during unloading, significantly improving operational flexibility and ease of use. At the same time, through the force transmission design of the rotating plate and the push rod, the pressure mechanism can evenly distribute the clamping force, thereby ensuring that the guide rail is subjected to uniform force throughout the entire fixing process, avoiding damage or deformation caused by excessive force at a single point.

[0019] 3. The lifting mechanism utilizes a combination of a base frame, fixed frame, swivel casters, universal casters, drive column, hydraulic cylinder, and connecting rod to provide the device with powerful lifting capabilities. The hydraulic cylinder, as the power core, can smoothly and efficiently complete the lifting and lowering of materials, easily handling even heavy guide rails. The combined design of the universal casters and swivel casters allows the device to move flexibly on the construction site, meeting the transportation needs under different working conditions. Meanwhile, the connecting rod, as a support frame, provides effective balance and ensures the stability of the device during lifting, preventing tilting or swaying and improving the safety and reliability of the entire device. These design details greatly improve the device's working efficiency while also providing strong protection for the safety of the construction site. Attached Figure Description

[0029] Please see Figures 1-5 A material transfer device for elevator construction includes a support frame 1. A fixing mechanism is installed on the support frame 1. The fixing mechanism includes a tray 2, support rods 3, mounting frames 4, push rods 5, cross members 6, top rods 7, clamping plates 8, and a pressure mechanism. Two sets of trays 2 are installed at the bottom of the support frame 1. Multiple sets of support rods 3 are installed between the two sets of trays 2. Multiple sets of mounting frames 4 are installed on the two sets of trays 2. Multiple sets of push rods 5 are slidably installed on both sides of the multiple sets of mounting frames 4. Cross members 6 are installed at the top of the multiple sets of push rods 5. Top rods 7 are installed on the top surface of the multiple sets of cross members 6. Clamping plates 8 are installed at the bottom of the multiple sets of push rods 5. The pressure mechanism includes a screw 9, a pressure plate 10, a knob 11, and a rotating plate 12. The screw 9 is rotatably installed on both sides of the multiple sets of mounting frames 4. The pressure plate 10 is connected to the outer wall of the multiple sets of screws 9. The knob 11 is installed at the top of the multiple sets of screws 9. The rotating plate 12 is rotatably installed on both sides of the multiple sets of mounting frames 4, with its inner side abutting against the top of the top rod 7.

[0030] Multiple sets of cross-shaped parts 6 are equipped with reset springs 13 on their bottom surfaces. Multiple sets of reset springs 13 are provided and are respectively connected to the outside of multiple sets of mounting frames 4.

[0031] Guide rods 14 are installed on both sides of multiple mounting frames 4, and the multiple guide rods 14 are slidably connected to the cross piece 6 and the guide rods 14 respectively.

[0032] The inner sides of multiple sets of clamping plates 8 are all equipped with soft pads 15.

[0033] The top ends of multiple sets of top rods 7 are all equipped with rounded corners.

[0034] Each of the multiple rotating plates 12 is equipped with a return spring 16, which is installed on the bottom surface of the multiple rotating plates 12 and connected to the outer wall of the mounting frame 4.

[0035] In this embodiment, when it is necessary to fix the guide rail, the guide rail is placed in the mounting frame 4, and then the knob 11 is turned to drive the screw 9 to rotate. The screw 9 rotates and engages with the pressure plate 10 through a thread, thereby controlling the pressure plate 10 to slide downward along the screw 9 and the guide rod 14. The bottom surface of the pressure plate 10 abuts against the top of the rotating plate 12, applying downward pressure to the rotating plate 12. This causes the rotating plate 12 to rotate along the mounting frame 4 while simultaneously squeezing the return spring 16 and pressing against the top rod 7. The top rod 7 pushes the cross member 6 to squeeze the return spring 13. The cross member 6 pushes the push rod 5 to slide along the mounting frame 4. The push rod 5 pushes the clamping plate 8 against the outer wall of the guide rail. The guide rail is clamped by contacting the outer wall of the guide rail with the soft pad 15. Tightening the knob 11 tightens the screw 9 and the pressure plate 10, thus fixing the guide rail. When the guide rail needs to be disassembled, the knob 11 is rotated in the opposite direction to drive the screw 9 to rotate in the opposite direction and engage with the pressure plate 10 in the opposite thread, causing the pressure plate 10 to move upward and release the contact with the rotating plate 12. The elastic reset of the return spring 16 pushes the rotating plate 12 to rotate outward and releases the contact with the push rod 7. The elastic reset of multiple sets of return springs 13 pushes the cross part 6 to move outward and pulls the push rod 5 to contact the clamping plate 8 to clamp and fix the outer wall of the guide rail, thus completing the disassembly of the guide rail.

[0036] Please see Figure 4 As one implementation of the lifting mechanism: a lifting mechanism is provided on the outside of the support frame 1. The lifting mechanism includes a base frame 17, a fixed frame 18, a rotating wheel 19, a universal wheel 20, a transmission column 21, and a hydraulic cylinder 22. The base frame 17 is located below the support frame 1, the fixed frame 18 is installed on one side of the base frame 17, the rotating wheel 19 is provided with two sets rotating at one end of the base frame 17, the universal wheel 20 is provided with two sets installed on the bottom surface of the fixed frame 18, the two ends of the transmission column 21 are rotatably connected to the support frame 1 and the fixed frame 18 respectively, and the hydraulic cylinder 22 is rotatably installed on the base frame 17 and its telescopic end is rotatably connected to the transmission column 21.

[0037] The top of the fixed frame 18 is rotatably mounted with a connecting rod 23. There are two sets of connecting rods 23, and the top of the connecting rods rotatably connects to both sides of the support frame 1.

[0038] More specifically, when the guide rail needs to be raised, the base frame 17 of the fixed frame 18 is pushed, and the rotating wheel 19 and universal wheel 20 are rotated to move it. The hydraulic cylinder 22 is operated so that its extension end pushes the top of the transmission column 21 to rise. At the same time, the bottom end rotates along the fixed frame 18, and the top of the transmission column 21 drives the support frame 1 to rise at the same time. The hydraulic cylinder 22 provides strong lifting power, which can cope with the heavy load requirements in material transportation. The support frame 1 and the fixed frame 18 are connected by two sets of connecting rods 23 at both ends, which balances and restricts the support frame 1. The setting of the connecting rods 23 can stabilize the movement trajectory of the support frame 1 when the hydraulic cylinder 22 extends and retracts, and avoid tilting or shaking during the lifting process, thereby improving the safety and stability of the entire device operation.

[0039] In summary, when the overall equipment is in use or operation, but it is necessary to fix the guide rail, place the guide rail in the mounting frame 4, and then turn the knob 11 to drive the screw 9 to rotate. The screw 9 rotates and engages with the pressure plate 10 through a threaded connection, thereby controlling the pressure plate 10 to slide downward along the screw 9 and guide rod 14. The bottom surface of the pressure plate 10 abuts against the top of the rotating plate 12, applying downward pressure to the rotating plate 12, causing the rotating plate 12 to rotate along the mounting frame 4 while simultaneously squeezing the return spring 16 and pressing against the push rod 7. The push rod 7 pushes the cross member 6 to squeeze the return spring 13, the cross member 6 pushes the push rod 5 to slide along the mounting frame 4, and the push rod 5 pushes the clamping plate 8 to... The guide rail is clamped to the outer wall. The soft pad 15 contacts the outer wall of the guide rail. Tightening the knob 11 tightens the screw 9 and the pressure plate 10, thus fixing the guide rail. When the guide rail needs to be disassembled, the knob 11 is rotated in the opposite direction to drive the screw 9 to rotate in the opposite direction and engage with the pressure plate 10 in the opposite thread, causing the pressure plate 10 to move upward and release the contact with the rotating plate 12. The elastic reset of the return spring 16 pushes the rotating plate 12 to rotate outward and releases the contact with the push rod 7. The elastic reset of multiple sets of return springs 13 pushes the cross part 6 to move outward and pulls the push rod 5 to contact the clamping plate 8 to clamp and fix the outer wall of the guide rail, thus completing the disassembly of the guide rail.

[0040] When the guide rail needs to be raised, the base frame 17 of the fixed frame 18 is pushed, and the rotating wheel 19 and universal wheel 20 are rotated to move it. The hydraulic cylinder 22 is operated so that its extension end pushes the top of the transmission column 21 to rise. At the same time, the bottom end rotates along the fixed frame 18, and the top of the transmission column 21 drives the support frame 1 to rise at the same time. The hydraulic cylinder 22 provides strong lifting power and can cope with the heavy load requirements in material transportation. The support frame 1 and the fixed frame 18 are connected by two sets of connecting rods 23 at both ends, which balances and limits the support frame 1. The setting of the connecting rods 23 can stabilize the movement trajectory of the support frame 1 when the hydraulic cylinder 22 extends and retracts, and avoid tilting or shaking during the lifting process, thereby improving the safety and stability of the entire device.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
