[0048] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0049] See Figures 1-3 This invention illustrates a preferred embodiment of auxiliary equipment for the installation of main equipment in a gas turbine power plant, comprising:

[0050] Body 1;

[0051] Adjustment drive device 2, which is mounted on the body 1;

[0052] Laser rangefinder 3, mounted on the output end of adjustment drive device 2, moves with the output end of adjustment drive device 2. Laser rangefinder 3 is used to measure the foundation dimensions of the main equipment of the gas turbine power plant to be installed and to locate the installation reference point; and

[0053] Marking pen 4 is located on the output end of the adjustment drive device 2. The marking pen 4 can move with the output end of the adjustment drive device 2.

The marking pen 4 is used to mark the installation reference point located by the laser rangefinder 3.

[0054] This utility model discloses an auxiliary installation device for the main equipment of a gas turbine power plant, comprising a body 1, an adjustment drive device 2, a laser rangefinder 3, and a marking pen 4. During operation, the adjustment drive device 2 first moves the laser rangefinder 3 to measure the foundation dimensions of the main equipment. Then, the adjustment drive device 2 adjusts the positions of the laser rangefinder 3 and the marking pen 4 to ensure that the laser rangefinder 3 measures within the designated installation area. The laser beam projected by the laser rangefinder 3 is used to locate the installation reference point. Simultaneously, the marking pen 4 marks the installation reference point located by the laser rangefinder 3 in real time. Through multi-point marking, the installation position of the main equipment to be installed is determined, thus achieving automatic positioning of the main equipment. Compared to traditional manual operation, this device uses laser ranging technology to eliminate human measurement errors. The adjustment drive device 2 ensures positioning accuracy, avoiding hand tremors and line-of-sight deviations in manual operation. Its automated marking process eliminates the subjectivity of experience-based judgment, ensuring that each marking point reaches the optimal position. Furthermore, the entire measurement and positioning process is completed automatically and continuously, significantly reducing the time spent on repeated measurements and manual marking in traditional methods, and greatly improving work efficiency. In addition, the equipment is easy to operate, reducing the technical requirements for operators, and improving work efficiency while ensuring installation accuracy. It effectively guarantees the accurate positioning of all components of the main equipment of the gas turbine power plant and the smoothness and sealing of pipeline connections, providing reliable technical support for the installation quality of the main equipment of the gas turbine power plant.

[0055] It should be noted that the auxiliary installation device for the main equipment of the gas turbine power plant also includes a control system. This control system is electrically connected to the regulating drive device 2 and the laser rangefinder 3. The control system includes a main control module, a ranging module, and an auxiliary module. The main control module uses an STM32 or STC89C52 microcontroller as its core processor, driving the laser emitter through an integrated PWM modulation circuit to achieve coordinated data acquisition and logic control. The ranging module is signal-connected to the main control module, enabling the laser rangefinder 3 to achieve nanosecond-level time interval measurements based on the pulse method measurement principle, thereby improving measurement accuracy. The auxiliary module interacts with the main control module via the BeiDou positioning system to perform real-time correction of spatial coordinates. The main control module coordinates the laser ranging function of the ranging module and the spatial positioning function of the auxiliary module, controlling the laser rangefinder 3 to perform at least three repeated measurements of the installation location. Based on the fusion processing of multiple sets of measurement data, it ensures that the spatial positioning accuracy of the main equipment installation location of the gas turbine power plant reaches its optimal level. (See also...) Figure 1 In one embodiment, the auxiliary equipment for installing the main equipment of the gas turbine power plant also includes:

[0056] The first mounting base 5 is connected to the output end of the adjustment drive device 2 and can move with the output end of the adjustment drive device 2. The laser rangefinder 3 is mounted on the first mounting base 5, and the marking pen 4 is mounted on the laser rangefinder 3. The first mounting base 5 supports the laser rangefinder 3 and the marking pen 4, facilitating their simultaneous installation on the output end of the adjustment drive device 2. Simultaneously, it ensures synchronized linkage between laser ranging and marking positioning, achieving integrated and precise positioning of measurement and marking, thereby improving equipment installation efficiency and accuracy.

[0057] See Figures 1-2 In one embodiment, the first mounting base 5 is hinged to the output end of the adjustment drive device 2 so that the first mounting base 5 can move relative to the output end of the adjustment drive device 2, which facilitates the adjustment of the mounting angle of the first mounting base 5.

[0058] The auxiliary equipment for the installation of main equipment in a gas turbine power plant also includes:

[0059] The locking mechanism 7 connects the first mounting base 5 and the output end of the adjusting drive device 2 to lock the position of the first mounting base 5. Thus, by hinged the first mounting base 5 to the output end of the adjusting drive device 2 and incorporating the locking mechanism 7, the first mounting base 5 possesses both adjustable angle and stable locking functions. This allows for flexible multi-angle adjustment of the laser rangefinder 3 and the marking pen 4, while ensuring positional stability during measurement and marking processes, thereby improving the adaptability and reliability of the installation and positioning of auxiliary equipment for the main equipment of the gas turbine power plant.

[0060] See Figures 1-2 In one embodiment, the auxiliary equipment for installing the main equipment of the gas turbine power plant also includes:

[0061] A hinged base 6 is provided, with its upper end fixedly connected to the output end of the adjustment drive device 2 and its lower end hinged to the upper end of the first mounting base 5. A first locking mechanism 7 connects the lower end of the hinged base 6 and the upper end of the first mounting base 5. By setting the hinged base 6 so that its upper end is fixedly connected to the output end of the adjustment drive device 2 and its lower end is hinged to the first mounting base 5, and by locking the hinged part in conjunction with the first locking mechanism 7, the first mounting base 5 can be flexibly adjusted with multiple degrees of freedom relative to the drive device, while ensuring the structural rigidity and positioning stability in the working state. This balances the adjustment flexibility and measurement reliability during the equipment installation and positioning process.

[0062] In one embodiment, the locking mechanism 7 includes:

[0063] The screw, the head of which abuts against the first sidewall of the hinge seat 6, and the shank of the screw passing through the hinge seat 6 and the first mounting seat 5; and

[0064] A nut is fitted onto the shank of the screw, with a threaded engagement between the nut and the shank. The nut abuts against the second sidewall of the hinge seat 6, which is positioned opposite the first sidewall of the hinge seat 6. Thus, the locking mechanism 7 clamps and fixes the hinge seat 6 and the first mounting seat 5 through the threaded engagement of the screw and nut. The bidirectional locking method, where the head of the screw abuts against the first sidewall of the hinge seat 6 and the nut abuts against the second sidewall, ensures both the stability of the connection and the reliability of the locking between the hinge seat 6 and the first mounting seat 5. It also facilitates quick adjustment and locking by rotating the nut, thereby improving operational convenience while maintaining installation and positioning accuracy.

[0065] In other embodiments, the locking mechanism 7 can also be an electromagnet assembly. An electromagnet assembly is provided on the contact surface between the hinge seat 6 and the first mounting seat 5. When energized, it generates magnetic attraction to fix the angle, and when de-energized, it releases the lock.

[0066] In other embodiments, the locking mechanism 7 may also be a ratchet mechanism. For example, the locking mechanism 7 includes a gear and a rack. The gear is mounted on the first mounting base 5, and the rack is telescopically mounted on the hinge base 6. When the rack and gear are engaged, the hinge base 6 and the first mounting base 5 are locked. When the rack and gear are disengaged, the lock is released.

[0067] In one embodiment, the laser rangefinder 3 is detachably connected to the first mounting base 5. This detachable connection allows the laser rangefinder 3 to be quickly disassembled for maintenance or replacement while ensuring structural stability after installation, thus balancing the flexibility of equipment use with the continuity of measurement operations.

[0068] In one embodiment, the first mounting base 5 is provided with a first latch, and the laser rangefinder 3 is provided with a second latch. The second latch is detachably connected to the first latch, thereby enabling the laser rangefinder 3 to be detachably connected to the first mounting base 5. Thus, by providing a first latch on the first mounting base 5 and forming a detachable connection structure with the second latch of the laser rangefinder 3, the laser rangefinder 3 achieves quick assembly and disassembly, ensuring a stable connection to meet measurement accuracy requirements while facilitating equipment maintenance and replacement, thereby improving operational convenience and efficiency.

[0069] In one embodiment, the first mounting base 5 and the laser rangefinder 3 are further connected by detachable fasteners such as screws or bolts. Thus, by adding detachable fasteners such as screws or bolts between the first mounting base 5 and the laser rangefinder 3, a dual connection mechanism is formed, combining the snap-fit ​​structure with the fastener. This retains the quick assembly and disassembly characteristics of the snap-fit ​​connection while significantly improving connection reliability through mechanical fastening, effectively preventing detachment due to snap-fit ​​failure. This ensures ease of operation while enhancing measurement stability.

[0070] In other embodiments, the laser rangefinder 3 and the first mounting base 5 can also be detachably connected in any of the following ways:

[0071] A permanent magnet or electromagnetic component is installed on the mating surface between the first mounting base 5 and the laser rangefinder 3 to achieve rapid positioning and fixation through magnetic attraction, and anti-slip textures can be added to enhance stability.

[0072] A T-shaped slide rail or dovetail groove is provided on the first mounting base 5, and a matching slider structure is configured at the bottom of the laser rangefinder 3. After being inserted laterally, it is locked by an elastic pin or knob.

[0073] A U-shaped elastic metal clamp is provided in the first mounting base 5, which clamps the cylindrical part of the laser rangefinder 3 by its deformation, and the clamping force is adjusted with the thumb screw.

[0074] See Figures 1-2 In one embodiment, the auxiliary equipment for installing the main equipment of the gas turbine power plant also includes:

[0075] A driving device 8 is mounted on the machine body 1 and is used to drive the machine body 1. Thus, by installing the driving device 8 on the machine body 1, the auxiliary equipment for installing the main gas turbine power plant equipment gains autonomous mobility. This allows the equipment to move flexibly between the location of the main gas turbine power plant equipment to be installed and the designated installation area. Simultaneously, it improves the efficiency of rapid deployment of equipment in different installation areas, reduces the labor intensity of manual handling, and enhances the automation level and operational flexibility of the overall construction process.

[0076] See Figure 1 In one embodiment, the driving drive device 8 includes:

[0077] Walking drive mechanism 81, the walking drive mechanism 81 is mounted on the body 1; and

[0078] Track 82 is wound around the output end of the walking drive mechanism 81 and can rotate with the output end of the walking drive mechanism 81. In this way, the walking drive mechanism 81 drives the track 82 to rotate, and the rotation of the track 82 can move the machine body 1 along the ground. In this way, the track 82 effectively reduces the ground pressure by increasing the contact area with the ground, reducing the risk of sinking, and is especially suitable for soft, muddy or uneven ground.

[0079] In other embodiments, the driving device 8 can also be a wheeled drive device, which can also drive the body 1 to move. It includes:

[0080] Walking drive mechanism 81, the walking drive mechanism 81 is mounted on the body 1; and

[0081] Wheel 83 is located at the output end of the walking drive mechanism 81. Wheel 83 can rotate with the output end of the walking drive mechanism 81 to drive the body 1 to move.

[0082] It should be noted that the specific structure of the aforementioned walking drive mechanism 81, the connection between the track 82 and the walking drive mechanism 81, and the connection between the wheel 83 and the walking drive mechanism 81 can all be found in existing patent literature, and will not be repeated here.

[0083] See Figures 1-2 In one embodiment, the adjustment drive device 2 includes:

[0084] Rotary drive mechanism 21, which is mounted on the body 1;

[0085] The support component 22 has its first end connected to the output end of the rotary drive mechanism 21. The support component 22 can rotate around the vertical rotation center line as the output end of the rotary drive mechanism 21 rotates. It can be understood that the vertical rotation center line is the vertical center line of the laser rangefinder 3 and the marker pen 4.

[0086] The first limiting arm 23 has its first end hinged to the second end of the support component 22;

[0087] The first telescopic drive mechanism 24 has a first fixed end and a first movable end at its two ends along its length. The first fixed end is hinged to the support component 22, and the first movable end is hinged to the first limiting arm 23. The first limiting arm 23 can swing up and down as the first movable end extends and retracts.

[0088] First connecting arm 25, the first end of the first connecting arm 25 is hinged to the second end of the support component 22;

[0089] The second connecting arm 26 has its first end hinged to the second end of the first connecting arm 25, and its second end is connected to the laser rangefinder 3. The marking pen 4 is placed on the laser rangefinder 3.

[0090] The second telescopic drive mechanism 27 has a second fixed end and a second movable end at its two ends along its length. The second fixed end is hinged to the second end of the first limiting arm 23, and the second movable end is hinged to the first connecting arm 25. The first connecting arm 25 can swing up and down as the second movable end extends and retracts.

[0091] The third telescopic drive mechanism 28 has a third fixed end and a third movable end at its two ends in the length direction, and the third fixed end is hinged to the second end of the first limiting arm 23.

[0092] A second limiting arm 29, the first end of which is hinged to a third movable end, and the second end of which is hinged to the first end of a second connecting arm 26, wherein the second limiting arm 29 can swing up and down as the third movable end extends and retracts; and

[0093] The third limiting arm 210 has its first end hinged to the first connecting arm 25, and its second end hinged to the second limiting arm 29. Thus, by adjusting the coordinated operation of the various components in the drive device 2, the laser rangefinder 3 and the marker pen 4 can achieve multi-degree-of-freedom movement, enabling precise adjustment of their positions and ensuring positioning accuracy. The laser rangefinder 3 and the marker pen 4 are horizontally rotated 360° by the cooperation of the rotary drive mechanism 21 and the support component 22, facilitating the determination of the installation position. Simultaneously, the coordinated action of the first telescopic drive mechanism 24, the second telescopic drive mechanism 27, and the third telescopic drive mechanism 28, combined with the linkage of the first limiting arm 23, the second limiting arm 29, and the third limiting arm 210, constitutes a multi-stage hinged composite adjustment drive device 2. This enables the laser rangefinder 3 and the marker pen 4 to have multi-degree-of-freedom spatial pose adjustment capabilities. Specifically, the first telescopic drive mechanism 24 adjusts the main pitch angle of the first limiting arm 23, and the first limiting arm 23 limits the second connecting arm 26. The second telescopic drive mechanism 27 and the third telescopic drive mechanism... Structure 28 forms a linkage fine-tuning mechanism, which, together with the constraint of the first limit arm 23, the second limit arm 29, and the third limit arm 210, ensures the stability of motion during the adjustment process. This expands the working range while achieving sub-millimeter-level positioning accuracy, ensuring more precise position adjustment of the laser rangefinder 3 and the marker pen 4. It not only meets the needs of large-scale rapid positioning, but also enables multi-dimensional flexible and fine adjustment through multi-level drive compensation. Ultimately, it ensures that the spatial coordinate measurement and marking of the installation reference point reach the engineering-grade accuracy requirements simultaneously. This solves the problems of traditional installation relying on manual measurement and experience judgment, which is prone to positioning deviations, leading to difficulties in subsequent pipeline connection, poor sealing, and affecting waste heat recovery efficiency and unit stability. In addition, the installation process is time-consuming and labor-intensive.

[0094] See Figures 1-2 In one embodiment, the adjustment drive device 2 further includes:

[0095] The second mounting base 220 is connected to the output end of the rotary drive mechanism 21, and the support component 22 is mounted on the second mounting base 220. By setting the second mounting base 220 as an intermediate connection structure between the rotary drive mechanism 21 and the support component 22, the rigidity transmission and load-bearing capacity of the overall device are enhanced, and at the same time, the connection between the support component 22 and the rotary drive mechanism 21 is facilitated.

[0096] See Figures 1-2 In one embodiment, the rotary drive mechanism 21 includes:

[0097] Rotary motor 211, the rotary motor 211 is mounted on the machine body 1;

[0098] The drive gear 212 is sleeved on the output shaft of the rotary motor 211, and the drive gear 212 can rotate with the output shaft of the rotary motor 211; and

[0099] Driven gear 213 is rotatably mounted on the body 1 and meshes with driving gear 212. Driven gear 213 can rotate with driving gear 212 and is connected to support component 22. Because the rotary drive mechanism 21 uses a rotary motor 211 in conjunction with the meshing transmission of driving gear 212 and driven gear 213, it can achieve high torque and low backlash precision rotation control, enabling support component 22 and its linkage mechanism to perform 360° rotation smoothly and reliably. This ensures the structural stability of laser rangefinder 3 and marking pen 4 during large-scale movement, and also ensures the accuracy of angle positioning through the precision meshing characteristics of gear transmission. Thus, while improving the reliability of the adjustment drive device 2, it further optimizes the spatial positioning accuracy.

[0100] In other embodiments, the rotary drive mechanism 21 may be a direct drive structure, consisting only of a rotary motor 211, which directly drives the support component 22 to rotate.

[0101] In other embodiments, the rotary drive mechanism 21 may include a rotary motor 211, a worm, and a worm wheel. The worm is connected to the output shaft of the rotary motor 211 and can rotate with the output shaft of the rotary motor 211. The worm wheel is rotatably mounted on the machine body 1 and meshes with the worm. The worm wheel is also connected to the support member 22. In this way, the rotation of the support member 22 can also be achieved.

[0102] In other embodiments, the rotary drive mechanism 21 may also be a hydraulic motor, which is mounted on the machine body 1. The output shaft of the hydraulic motor is connected to the support component 22, and the support component 22 can rotate with the output shaft of the hydraulic motor.

[0103] See Figures 1-2 In one embodiment, the first telescopic drive mechanism 24, the second telescopic drive mechanism 27, and the third telescopic drive mechanism 28 are all hydraulic cylinders.

[0104] In other embodiments, the first telescopic drive mechanism 24, the second telescopic drive mechanism 27, and the third telescopic drive mechanism 28 can all be cylinders.

[0105] See Figure 2 In one embodiment, the body 1 has a cavity 11, and the rotary drive mechanism 21 is located inside the cavity 11 to accommodate the rotary drive mechanism 21 and prevent the rotary drive mechanism 21 from occupying the external space of the body 1.

[0106] The working principle of the auxiliary equipment for installing the main equipment of a gas turbine power plant according to this utility model is as follows:

[0107] In operation, the machine body 1 is first moved by the driving device 8, thus bringing the entire equipment to the site and moving it to the designated position. At this time, the control system drives the laser rangefinder 3 to measure the foundation dimensions of the main equipment of the gas turbine power plant to be installed. After three measurements, the average value is taken and the data is stored. Then, the machine body 1 is moved to the designated installation area. At this time, the laser rangefinder 3 is activated to locate the installation position and transmit the data to the control system. Then, the control system controls the rotary motor 211 to start, thereby driving the laser rangefinder 3 and the marker pen 4 to rotate in the designated direction. Then, the first telescopic drive mechanism 24, the second telescopic drive mechanism 27, and the third telescopic drive mechanism 28 are activated to measure the laser rangefinder's position. After adjusting the positions of the laser rangefinder 3 and the marker pen 4, the laser rangefinder 3 is used to locate the installation reference point, and the marker pen 4 is used to mark the located installation reference point. This multi-point marking determines the placement position of the main equipment of the gas turbine power plant to be installed, ensuring smooth and stable connection of each pipeline in the main equipment of the gas turbine power plant. Because the laser rangefinder 3 monitors the position in real time and is combined with the adjustment drive device 2 for precise positioning, the equipment can be flexibly adjusted in multiple dimensions to achieve automated operation. This solves the problems of traditional installation relying on manual measurement and experience judgment, which is prone to positioning deviation, leading to difficulties in subsequent pipeline connection, poor sealing, affecting waste heat recovery efficiency and unit stability, as well as the problems of long installation time and high labor costs.

[0108] In summary, the auxiliary equipment for installing the main equipment of a gas turbine power plant according to this utility model has the following advantages:

[0109] By adjusting the various components in the drive device 2 to cooperate with each other, the laser rangefinder 3 and the marking pen 4 can be flexibly adjusted in multiple dimensions and can be remotely operated to achieve automated operation. The marking pen 4 can mark the installation reference point measured by the laser rangefinder 3, thereby determining the placement position of each component of the main equipment of the gas turbine power plant more quickly.

[0110] By cooperating with each module of the control system, the laser rangefinder 3 can quickly and accurately measure the installation position, and take no less than three measurements to ensure more accurate positioning and improve positioning accuracy.
