Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical pipeline installation, and in particular to a multi-angle adjustable laser positioning auxiliary device for electromechanical pipeline installation. Background Art

[0002] Mechanical and electrical pipelines are a general term for various pipes and cables used to transmit electrical energy, signals, fluids and other media in building mechanical and electrical installation projects, including electrical pipelines, water supply and drainage, fire protection pipelines, ventilation and air conditioning pipelines, etc.

[0003] Traditional electromechanical pipeline installation mostly uses wire drawing or plumb bobs. However, these traditional methods rely on manual operation and require collaboration between multiple people to complete horizontal and vertical calibration. In complex pipeline corridors, each pipeline section needs to be repeatedly measured, and single positioning takes a long time. This calibration method leads to low construction efficiency and affects construction progress.

[0004] Therefore, the present invention provides a multi-angle adjustable laser positioning auxiliary device for the installation of electromechanical pipelines. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and provide a multi-angle adjustable laser positioning auxiliary device for the installation of electromechanical pipelines.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a multi-angle adjustable laser positioning auxiliary device for electromechanical pipeline installation, comprising a supporting bottom bar;

[0007] The rotation adjustment assembly includes a connecting block fixedly connected to the inner side of the supporting bottom rod, the internal thread of the connecting block is connected to a threaded column, the connecting block is fixedly connected to a cross bar on the side away from the supporting bottom rod, the top end of the cross bar is rotatably connected to a rotating shaft, the outer side of the rotating shaft is fixedly connected to a ratchet, the top end of the supporting bottom rod is fixedly connected to a column, the outer side of the column is rotatably connected to a pawl, and the top end of the rotation adjustment assembly is fixedly connected to an auxiliary adjustment assembly.

[0008] As a preferred embodiment, the auxiliary adjustment assembly includes a vertical rod fixedly connected to the top end of the rotating shaft, and the top end of the vertical rod is rotatably connected to a rotating block 1.

[0009] As a preferred embodiment, one end of the rotating block away from the vertical rod is fixedly connected to the extension rod, and the ends of the vertical rod and the extension rod close to each other are both fixedly connected to the rotating block.

[0010] As a preferred embodiment, the interior of one of the rotating blocks is rotatably connected to a cylinder, and the interior of the other rotating block is rotatably connected to a driving end of the cylinder.

[0011] As a preferred embodiment, one end of the extension rod away from the rotating block 1 is fixedly connected to the rotating block 2.

[0012] As a preferred embodiment, a handle is fixedly connected to the outer side of the vertical pole.

[0013] As a preferred embodiment, the ratchet and the pawl are meshingly connected.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are

[0015] 1. When the threaded column is rotated, its threaded engagement with the connecting block produces axial displacement, pushing the crossbar to tilt around the supporting bottom bar, thereby changing the rotation angle of the shaft. At the same time, the ratchet and pawl engage in a linkage, and when the shaft rotates to the target angle, the pawl automatically engages the ratchet tooth groove to form a rigid self-locking mechanism. With this design, the combination of threaded transmission and ratchet pawl can achieve rapid coarse angle adjustment while preventing angle rebound through mechanical self-locking, ensuring stability. Compared to replacing traditional manual repeated calibration methods, the threaded adjustment and self-locking mechanism can complete angle fixation in a single pass, reducing the number of repeated measurements.

[0016] 2. When the cylinder is driven, the hinged rotating blocks at both ends push the extension rod to rotate around the vertical pole. At the same time, the second rotating block rotates with the extension rod around the axis, ultimately driving the laser emitter to achieve pitch adjustment. Combining the circumferential rotation of the first rotating block with the adjustment of the second rotating block; this design, by utilizing the linear drive of the cylinder and the degree of freedom of the hinged structure, can achieve high-precision fine-tuning of the laser emitter, and can achieve three-dimensional multi-directional adjustment to adapt to complex pipeline corridor environments.

[0017] 3. The motor drives the transmission rod to rotate, driving the worm and worm gear to engage with each other. The extension column fixed with the worm gear drives the active bevel gear to engage with the driven bevel gear, and finally drives the laser transmitter to rotate through the rotating column and the mounting column. At the same time, combined with the two-way rotation linkage of the rotating block 1 and the rotating block 2, this design realizes the high reduction ratio and self-locking characteristics provided by the worm and worm gear transmission, ensuring the adjustment accuracy and static stability. The transfer structure decomposes the single axial motion into multi-directional linkage, forming a multi-axis compound motion in three-dimensional space, achieving angle coverage without dead angles.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a multi-angle adjustable laser positioning auxiliary device for electromechanical pipeline installation, comprising a supporting bottom bar 1;

[0032] The rotary adjustment assembly 2 includes a connecting block 21 fixedly connected to the inner side of the supporting bottom bar 1, the internal thread of the connecting block 21 is connected to a threaded column 22, the side of the connecting block 21 away from the supporting bottom bar 1 is fixedly connected to a cross bar 23, the top end of the cross bar 23 is rotatably connected to a rotating shaft 24, the outer side of the rotating shaft 24 is fixedly connected to a ratchet 25, the top end of the supporting bottom bar 1 is fixedly connected to a column 26, the outer side of the column 26 is rotatably connected to a pawl 27, and the ratchet 25 and the pawl 27 are meshed;

[0033] The supporting bottom bar 1 serves as the basic supporting structure of the entire laser positioning auxiliary device, providing a stable installation platform for other components. The connecting block 21 connects the supporting bottom bar 1 and other components of the rotation adjustment assembly 2. The internal threaded structure is used to cooperate with the threaded column 22, which can fix the threaded column 22 inside it. At the same time, it serves as a connection node for other components such as the cross bar 23. The threaded column 22 cooperates with the thread inside the connecting block 21. By rotating the threaded column 22, its position in the connecting block 21 can be adjusted, thereby changing the angle of the rotation adjustment assembly 2. The cross bar 23 serves as a fulcrum for connecting the rotating shaft 24. One end is fixedly connected to the connecting block 21, and the other end provides an installation base for the rotating shaft 24, so that the rotating shaft 24 can realize the rotation function at the top of the cross bar 23, providing a stable installation position for the rotating shaft 24, ensuring that the rotating shaft 24 can rotate smoothly, so that the components connected to the rotating shaft 24 can be smoothly moved. When the rotating shaft 24 and the ratchet 25 are rotated to a suitable angle, the pawl 27 will be stuck in the tooth groove of the ratchet 25 under the action of external force, preventing the ratchet 25 from reversing, thereby fixing the position of the rotating shaft 24.

[0034] like Figure 1 、 Figure 3 and Figure 4As shown, the top of the rotation adjustment component 2 is fixedly connected to the auxiliary adjustment component 3, and the auxiliary adjustment component 3 includes a vertical rod 31 fixedly connected to the top of the rotating shaft 24, the top of the vertical rod 31 is rotatably connected to a rotating block 1 32, and the end of the rotating block 1 32 away from the vertical rod 31 is fixedly connected to an extension rod 33, and the vertical rod 31 and the extension rod 33 are both fixedly connected to a rotating block 34 at one end, one of the rotating blocks 34 is rotatably connected to a cylinder 35, and the other rotating block 34 is rotatably connected to the driving end of the cylinder 35. The end of the extension rod 33 away from the rotating block 1 32 is fixedly connected to a rotating block 2 36, and the outer side of the vertical rod 31 is fixedly connected to a handle 38.

[0035] The vertical rod 31 serves as the main supporting structure of the auxiliary adjustment component 3. The vertical rod 31 is fixed to the top of the rotating shaft 24, providing an installation foundation for subsequent rotating block 1 32, rotating block 2 36 and other components. The rotating block 1 32 is installed at the top of the vertical rod 31 and can rotate around the vertical rod 31. It is mainly used to connect the extension rod 33 and can drive the extension rod 33 to rotate together to achieve preliminary adjustment of the angle of the extension rod 33. One end of the extension rod 33 is fixed to the rotating block 1 32, and the other end is connected to the rotating block 2 36. As the intermediate component connecting the rotating block 1 32 and the rotating block 2 36, it plays the role of extending and transmitting motion, and at the same time provides support for the installation of the laser emitter 37. The rotating block 34 is fixed to the vertical rod 31 and the extension rod 3 respectively. 3, there is a rotating connection structure inside for installing a cylinder 35, so that the cylinder 35 can be connected to the vertical pole 31 and the extension rod 33 and can rotate relative to each other. The cylinder 35 is installed between the rotating blocks 34. Through the telescopic drive of the cylinder 35, the extension rod 33 and the rotating block 1 32 are pushed or pulled to rotate around the vertical pole 31, thereby achieving precise control of the angle of the extension rod 33. The rotating block 2 36 is installed at the end of the extension rod 33 away from the rotating block 1 32, and is used to fix and support the laser emitter 37, while allowing the laser emitter 37 to rotate within a certain range to achieve the purpose of angle adjustment. The laser emitter 37 is installed on the outside of the vertical pole 31, which is convenient for the operator to hold and is used to manually adjust the rotation angle;

[0036] like Figure 5 and Figure 6 As shown, one end of the auxiliary adjustment assembly 3 is fixedly connected to the driving assembly 4, and the driving assembly 4 includes a mounting plate 41 fixedly connected to the top of the second rotating block 36. A motor 42 is mounted on the mounting plate 41. The driving end of the motor 42 is fixedly connected to a transmission rod 43, and the outer side of the transmission rod 43 is fixedly connected to a worm 44.

[0037] The mounting plate 41 is fixedly connected to the top of the second rotating block 36 and serves as a support and mounting base for the motor 42. It provides a stable fixed position for the motor 42 and ensures that the motor 42 can maintain stable operation during operation. The motor 42 is mounted on the mounting plate 41 and serves as the power source of the drive assembly 4. Through the rotational motion of its driving end, it converts electrical energy into mechanical energy to provide power for the rotation of the transmission rod 43. The transmission rod 43 is fixedly connected to the driving end of the motor 42 and is used to transmit the rotational motion of the motor 42 to other components, thereby driving the laser emitter 37 to rotate or adjust the angle.

[0038] like Figure 5 and Figure 6 As shown, the auxiliary adjustment component 3 is internally rotatably connected to the fine-tuning component 5, and the fine-tuning component 5 includes a rotating column 51 rotatably connected to the rotating block 2 36, the outer side of the rotating column 51 is fixedly connected to the driven bevel gear 1 52, and the outer end of the rotating column 51 away from the driven bevel gear 1 52 is fixedly connected to the driven bevel gear 2 53, the outer side of the rotating column 51 is fixedly connected to the mounting column 54, the top of the supporting bottom rod 1 of the mounting column 54 is fixedly connected to the extension column 55, the outer side of the extension column 55 is fixedly connected to the worm gear 56, and the bottom end of the extension column 55 is fixedly connected to the driving bevel gear 57, the driven bevel gear 1 52 and the outer side of the driven bevel gear 2 53 are meshed with the driving bevel gear 57, the worm 44 and the worm gear 56 are meshed, and the bottom end of the mounting column 54 is fixedly connected to the laser emitter 37;

[0039] The rotating column 51 serves as a mounting carrier for the driven bevel gear 1 52 and the driven bevel gear 2 53, and at the same time transmits power from the active bevel gear 57 to subsequent transmission components. The driven bevel gear 1 52 and the driven bevel gear 2 53 are meshed with the active bevel gear 57, changing the transmission direction of power and transmitting the rotational motion to the rotating column 51. The mounting column is fixedly connected to the outer side of the rotating column 51, and the bottom end thereof is fixedly connected to the laser emitter 37, which plays a role in supporting and fixing the laser emitter 37, and at the same time connects the laser emitter 37 to the transmission system of the fine-tuning component 5. Through the mounting column 54, the laser emitter 37 can be stably mounted on the fine-tuning component 5, ensuring that the position and angle of the laser emitter 37 can be precisely controlled during the fine-tuning process, thereby improving the stability of the laser positioning. The extension column 55 connects the mounting column 54 and the active bevel gear 57, serving as a support structure for the entire fine-tuning component 5.

[0040] Working principle:

[0041] like Figure 1 - Figure 6 As shown:

[0042] When in use: first, by rotating the threaded column 22, the threaded fitting depth in the connecting block 21 is adjusted to change the initial angle between the connecting block 21 and the cross bar 23, and then the cross bar 23 is driven to change the tilt angle around the supporting bottom bar 1. Secondly, the vertical rod 31 is rotated by the handle 38, and the rotating shaft 24 rotates synchronously with the cross bar 23. The ratchet 25 and the pawl 27 are engaged to form a self-locking connection. When it is rotated to the target angle, the pawl 27 automatically snaps into the tooth groove of the ratchet 25 to achieve angle fixing. When auxiliary adjustment is performed, the rotating blocks 34 at both ends of the cylinder 35 are hinged for telescopic movement, which can drive the extension rod 33 and the rotating block 1 32 to form an angle change, and then push the rotating block 2 36 to rotate around the axis of the extension rod 33. Through the precise telescopic control of the cylinder 35, the laser emitter 37 installed in the rotating block 2 36 completes the pitch angle adjustment. Then, the motor 42 is energized to work, and the driving end rotates to drive the transmission rod 43 to rotate, and the transmission rod 43 drives the worm 44 to rotate. The worm 44 meshes with the worm gear 56, driving the extension column 55, to which the worm gear 56 is fixed, to rotate. The extension column 55 is connected to the driving bevel gear 57, which meshes with the driven bevel gear 1 52 and the driven bevel gear 2 53, respectively, thereby driving the rotation column 51. The rotating column 51 rotates the mounting column 54, and the laser emitter 37 at the bottom of the mounting column 54 changes angle as the mounting column 54 rotates. At the same time, the bidirectional rotation of the rotating block 1 32 and the rotating block 2 36 ultimately achieves multi-axis angular adjustment of the laser emitter 37 in three-dimensional space, realizing multi-angle, high-precision adjustment of the laser emitter 37 and improving the efficiency and accuracy of electromechanical pipeline installation.
