Description

Technical Field

[0001] This invention belongs to the field of large-scale mechanical equipment assembly technology, and relates to a large-scale lid linear adjustment auxiliary support device and its usage method. Background Technology

[0002] During the assembly and commissioning of large-scale mechanical equipment, operators not only need to precisely install the complete functional components into the equipment compartment according to assembly technical requirements, but also need to debug its related functions after the assembly work is completed. Therefore, a clearance of S = 0.01-1.5m is set around the equipment compartment. 2 Various types of covers of different sizes and quantities constitute the windows for later ground-based commissioning, maintenance, and inspection, thereby meeting relevant commissioning and maintenance needs. Currently, for covers with smaller areas, operators only need to use process screws to assist in their installation on the skin structure of the cover on large mechanical equipment. However, for covers with an area of ​​S = 1.5㎡, operators need to enter the equipment compartment to carry out related installation and commissioning work. This requires opening the large cover and relying on the surrounding structure or having another operator manually support it for a long time until the commissioning work is completed. While the above methods can effectively complete the installation and commissioning of equipment compartments, several issues arise in practice: First, for covers exceeding 1.5 square meters, although they can be secured to the surrounding structure of large machinery using a single-sided hinge, the weight of the cover (over 40 kg) poses a safety risk of damaging the finished product once the surrounding structure is assembled, leading to unnecessary economic losses and increased manufacturing costs. Second, for large covers that cannot be directly secured to the surrounding structure of large machinery, another operator must provide manual support for extended periods to complete the commissioning work. This not only wastes manpower but also increases operator fatigue, and a lapse in concentration could cause the cover to slip, posing a significant safety hazard. Third, large covers require frequent opening and closing at different angles for operation and commissioning, increasing operational difficulty and workload. Summary of the Invention

[0003] The purpose of this invention is to develop a novel auxiliary support device for linear adjustment of the large cap in a large mechanical equipment compartment, which integrates cap angle linear adjustment, cap fast locking, and electric control drive functions. This device replaces the high-intensity working conditions caused by long-term manual operation, thereby improving work efficiency, reducing the number of operators, and offering excellent flexibility. It has a particularly wide range of applications.

[0004] The technical solution of the present invention is as follows:

[0005] The large-cap linear adjustment auxiliary support equipment includes a telescopic device mechanical adjustment system, a fixing device quick-locking system, and an electronically controlled linear adjustment system. The telescopic device mechanical adjustment system uses a double-ended synchronously adjustable mechanical pull rod structure to simultaneously extend or shorten the telescopic length of the entire equipment, further meeting the operator's needs. The fixing device quick-locking system uses a pin locking mechanism to stably fix both ends of the entire equipment to the relevant caps and structures of the large mechanical equipment. The electronically controlled linear adjustment system is the core system of the entire equipment. Its main function is to control the telescopic length of the entire equipment through electrical signals, and at the same time, it synchronously feeds back the information to this system for comprehensive display and monitoring.

[0006] The aforementioned telescopic device mechanical adjustment system includes a main support, a reverse threaded telescopic rod, a forward threaded telescopic rod, a universal bearing, a forward threaded worm gear, a drive shaft, a reverse threaded worm gear, a limit pin, an end cap, a fixing pin, and an axial rotation connector, the specific structure of which is as follows: Figure 1 , Figure 2 As shown.

[0007] The main support of the equipment is made of high-strength, wear-resistant aluminum material and has a convex cavity structure. Its main function is to provide a main mounting support for the entire equipment. The upper end of the support is a rectangular open cavity, which mainly provides a main mounting support for the servo drive device and universal bearings and other transmission parts. The threaded hole on side A of the lower end of the support is a positive thread and is connected to a positive thread telescopic rod. The threaded hole on side B is a negative thread and is mainly connected to a negative thread telescopic rod.

[0008] The forward threaded telescopic rod is mainly made of high-hardness, wear-resistant aluminum material and has a cylindrical shape. It is connected to the lower end A side of the main support of the equipment through its own forward thread. Its main function is to change the telescopic length of the entire equipment and connect the main support of the equipment to the axial rotation connector. The forward threaded telescopic rod and the axial rotation connector are connected by welding.

[0009] The reverse threaded telescopic rod is mainly made of high-hardness, wear-resistant aluminum material and has a cylindrical shape. It is connected to the lower end B side of the main support of the equipment through its own forward thread. Its main function is to change the telescopic length of the entire equipment and connect the main support of the equipment to the second axial rotation connector. The reverse threaded telescopic rod and the second axial rotation connector are connected by welding.

[0010] The universal bearing is a precision bearing whose bearing bore can be adjusted within a certain angle range. Two universal bearings are installed in this equipment, respectively on the left and right sides of the square cavity on the upper part of the main support of the equipment. It is interference-fitted with the cavity bearing of the main support of the equipment. Its main function is to provide a rotational support with a unified axis of rotation for the output shaft and transmission shaft of the servo drive device, so as to avoid the output shaft and transmission shaft of the servo drive device from directly contacting the main support of the equipment, which not only has large rotational friction, but also causes serious wear on the relatively contact parts, affecting the service life.

[0011] The forward threaded turbine is made of high-hardness, wear-resistant steel and is configured with a forward thread. Its main functions are: first, to synchronously transmit the angular displacement of the output shaft of the servo drive device to the forward threaded telescopic rod, thereby realizing the change of the telescopic length of the forward threaded telescopic rod relative to the main support of the equipment; second, to synchronously transmit the angular displacement of the output shaft of the servo drive device to the reverse threaded turbine through the transmission shaft, thereby driving the reverse threaded telescopic rod to rotate synchronously.

[0012] The drive shaft is made of high-hardness, wear-resistant steel and has a cylindrical shape. Its main functions are: first, to provide a synchronous rotating shaft for the reverse threaded turbine and the forward threaded turbine; and second, to synchronously transmit the angular displacement of the servo drive device to the reverse threaded turbine, thereby driving the reverse threaded telescopic rod to rotate and realize the overall length extension function of the equipment.

[0013] The reverse threaded turbine is made of high-hardness, wear-resistant steel and is configured with reverse threads. Its main function is to synchronously transmit the angular displacement of the drive shaft to the reverse threaded telescopic rod.

[0014] The limiting pins are made of high-hardness, wear-resistant steel. There are four in total in this device. Their main function is to fix the interconnecting parts between the reverse threaded turbine, the forward threaded turbine, the drive shaft and the output shaft of the servo drive device, so as to prevent the position from moving during operation and thus affecting the overall function.

[0015] The end cap is made of aluminum and has a rectangular thin-walled structure. It is fixed to the upper cavity of the main support of the equipment by fixing nails. Its main function is to prevent foreign objects from entering the cavity of the main support of the equipment, affecting the overall transmission effect, and thus causing the equipment to malfunction.

[0016] The fixing screws are stainless steel internal hexagon screws, and four are provided in this equipment. Their main function is to fix the end cap to the upper cavity of the main support of the equipment.

[0017] The axial rotary connector is mainly made of wear-resistant steel and is a mechanical structure composed of cylindrical parts C and D that can rotate 360° relative to each other around the axis. Two of them are provided in this device. Their main function is to connect the first adjusting joint to the reverse threaded telescopic rod and the second adjusting joint to the forward threaded telescopic rod by welding.

[0018] The aforementioned quick-locking system for the fixing device comprises an adjusting joint, a universal locking bearing, a locking pin, and an adjusting nut, with the specific structure as follows: Figure 1 , Figure 2 As shown.

[0019] The adjusting joint is mainly made of high-hardness, wear-resistant aluminum material, and has a ring joint structure. There are two in this equipment. Its main function is to provide a fixed support for two universal locking bearings. The two are interference fit. The other end is connected to the D end of the axial rotation connector by welding.

[0020] The universal locking bearing is a precision finished bearing. Two are installed in this equipment. Its main functions are: first, to provide a sliding and adjustable guide hole for the locking pin; and second, due to the universal function of the universal locking bearing, it can be stably connected to the cover support arm B or the mechanical structure support arm A at a certain angle, thereby increasing the applicability of the equipment.

[0021] The locking pin is made of high-hardness, wear-resistant steel and has a stepped shaft structure. There are two in this device. The smaller diameter shaft is threaded and its main function is to connect the entire device with the cover support arm B and the mechanical structure support arm A.

[0022] The adjusting nut is made of aluminum alloy and has a stepped shaft-shaped nut structure. Two of them are installed in this device and installed on the threaded end of the small diameter shaft of the locking pin. Its main function is to change its position relative to the locking pin so that the large diameter cylindrical end of the locking pin tightly presses the end face of the cover support arm B or the mechanical structure support arm A against the end face of the two universal locking bearings.

[0023] The aforementioned electronic control device linear adjustment system includes a servo drive device, a hexagonal socket fastener, an integrated electronic control device, a communication cable, and a warning light, with the specific structure as follows: Figure 3 As shown.

[0024] The servo drive device mainly consists of two parts: the first part is the servo motor running device, which mainly receives the electrical signal control command from the integrated electronic control device and converts it into a rotational displacement signal, which is then transmitted to the reduction device in the second part through the output shaft; the second part is the reduction device, which can convert the output rotational signal of the servo motor shaft into a high-torque, low-speed rotational signal, thereby driving the positive threaded turbine and subsequent transmission parts to operate.

[0025] The data signal conversion model involved in the overall design of the servo drive device is: S=F*A*W1, where S is the variable of the servo drive device output angle transformed into linear length displacement; F is the linear length displacement generated by the servo drive device rotating one revolution; A is the number of electrical signal pulses; and W1 is the rotation angle of the single-pulse servo drive device.

[0026] The relevant data conversion model involved in the overall design of the speed reduction device is as follows:

[0027] T = T1 * i, where T is the output torque of the speed reducer, T1 is the input torque of the speed reducer, and i is the overall speed reduction ratio of the speed reducer.

[0028] i = (N2 / N1)*(N4 / N3)*...(Nn / Nn-1), where i is the overall reduction ratio of the reduction device, and N1, N2, N3...Nn are the number of teeth of adjacent gears. In this device, the number of reduction stages of the reduction device can be determined according to the actual use, and then the reduction ratio i can be determined.

[0029] The hexagonal socket head cap screws are stainless steel hexagonal socket head cap screws. There are four in total in this device. Their main function is to install and fix the servo drive device on the left side of the cavity above the main support of the equipment.

[0030] The communication cable is a signal adapter cable, whose main function is to transmit the drive electrical signals from the integrated electronic control device to the servo drive device and the working status command signals to the warning lights. At the same time, it synchronously feeds back parameters such as the length and angle of the entire device.

[0031] The warning light is a warning device with a red or green signal indicating the working status. Its main function is to indicate or warn the operator when starting or stopping the operation.

[0032] The integrated electronic control device is a device that displays both output and input commands simultaneously. Its main function is to allow the operator to adjust the overall length of the equipment according to work requirements during actual operation.

[0033] Advantages of this invention:

[0034] (1) The mechanical structure of this invention is novel, highly stable, versatile and widely applicable. In the process of assembling and debugging the finished products of large mechanical equipment, it can efficiently and quickly realize the opening and angle of the equipment hatch cover. In different working environments, the operator can independently complete the relevant installation and debugging work. Compared with the past, the number of operators has been reduced from 2 to 1, and the work efficiency has been increased by 1 time.

[0035] (2) This invention patent innovatively designs an innovative tooling that integrates three functional systems: a telescopic device mechanical adjustment system, a fixed device quick locking system, and an electrical control device linear adjustment system. This completely solves the pain points and difficulties caused by operators holding the lid for a long time during previous work processes, such as high labor intensity for operators, a large number of operators, and significant safety hazards.

[0036] (3) The present invention uses an electronic control device linear adjustment system as a power source to drive the device. The operator can drive the opening and angle of the large cap by holding the integrated electronic control device 18. In this way, the operator can remotely control the device while working in a relatively distant area, which improves the automation level of the device, further simplifies the workflow, reduces the difficulty of operation, reduces the workload, and avoids unnecessary safety risks.
