Description

Technical Field

[0001] This application relates to the field of surveying equipment technology, and in particular to a surveying equipment mounting bracket. Background Technology

[0002] A surveying device mounting bracket is a specialized component used to support and fix surveying instruments. It is mostly made of sturdy materials such as metal and achieves stable installation of instruments through specific structural design. Its main function is to ensure that the instrument is fixed in position and accurate in attitude during the surveying process, and to reduce the impact of external interference on measurement accuracy. It is widely used in fields such as engineering construction, geological exploration, and topographic mapping, and is an important auxiliary tool to ensure the smooth progress of surveying work and the reliability of data.

[0003] A stable base is formed by connecting the support structure to the ground or an object. The measuring instrument is fixed and its angle and height are adjusted by the adjustment mechanism. The rigid support and shock absorption design are used to counteract external vibrations, wind and other interferences, and keep the instrument's posture unchanged. The positioning components ensure that the instrument's coordinate system is aligned with the measurement reference, so as to achieve accurate data acquisition.

[0004] In the existing technology, some surveying device mounting frames use a simple snap-on telescopic structure, which is prone to loosening due to external impacts during use. Although some mounting frames are equipped with telescopic reinforcement components, the operation is cumbersome, making it difficult to quickly complete the telescopic and reinforcement in emergency surveying tasks, resulting in the surveying device tilting and affecting the accuracy of the measurement data.

A damping shaft is rotatably connected to the top of the scale shaft. A fine-tuning component is rotatably connected inside the damping shaft.

[0012] By adopting the above technical solution, the receiving block is slidably connected to the base, and two limiting grooves are symmetrically distributed on both sides of the receiving block. The spring pushes the concave plate into the tooth groove of the receiving block, the pressing column presses down, and the squeezing block pushes the concave plate through the inclined surface to compress the spring and unlock. The scale axis on the top of the gimbal has a 360-degree circumferential scale, and the fine adjustment component adopts a worm gear to achieve precision adjustment.

[0013] Preferably, the fine-tuning component includes a worm gear, the worm gear being externally rotatably connected to the inside of the damping shaft, a connecting shaft being fixedly connected to the top of the scale shaft, and a worm wheel being fixedly connected to the outside of the connecting shaft;

[0014] By adopting the above technical solution, in the fine-tuning component, the worm gear is installed in the damping shaft through a high-precision bearing, forming a transmission pair with the worm wheel on the connecting shaft, which can realize precise fine-tuning of the surveying instrument angle.

[0015] Preferably, the outer side of the main wedge block is in contact with the inner wall of the outer sleeve, and the outer side of the secondary wedge block is slidably connected to the inside of the main wedge block;

[0016] By adopting the above technical solution, the main wedge block fits tightly against the inner wall of the outer sleeve, and is embedded in the slot after being pressed to achieve initial fixation. The secondary wedge block is slidably placed inside the main wedge block and pops out after the main block is fixed, thus reinforcing the telescopic structure for the second time.

[0017] Preferably, the outer side of the inclined post is engaged with the inclined tooth, and the outer side of the inclined post is slidably connected to the inside of the middle sleeve;

[0018] By adopting the above technical solution, the inclined column and the inclined tooth are precisely engaged at an inclined angle, and can slide axially along the inner wall of the middle sleeve. The engagement state is maintained by the spring force, so as to achieve rapid self-locking and stable fixation after the inner sleeve is extended or retracted.

[0019] Preferably, the outer side of the concave plate is slidably connected to the inside of the limiting groove, the top of the extrusion block is in contact with the inner wall of the concave plate, and the outer side of the worm gear is meshed with the outer side of the worm wheel.

[0020] By adopting the above technical solution, the concave plate slides flexibly in the limiting groove, the compressed block pushes the compressible spring to release the limiting position, and the worm and worm wheel mesh precisely, so as to realize the fine adjustment of the angle of the surveying device.

[0021] Preferably, the top of the fourth spring is fixedly connected to the inner wall of the base, and the bottom of the fourth spring is fixedly connected to the bottom inner wall of the pressing column;

[0022] By adopting the above technical solution, the spring is vertically installed between the base and the pressing column. Its top is firmly fixed to the inner wall of the base, and its bottom is tightly connected to the inner wall of the bottom of the pressing column, providing elastic support for the pressing column to reset.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this utility model, pressing the airbag drives air into the outer sleeve, and then the air pressure pushes the piston to slide. The piston squeezes the hydraulic oil in the hydraulic pipe, pushing the main wedge block to extend and engage with the groove on the inner wall of the outer sleeve. After the middle sleeve is in place, the main wedge block releases the pressure on the secondary wedge block. The spring pushes the secondary wedge block to engage with the inner wall of the outer sleeve. The piston pushes the middle sleeve to extend slowly, and the inner sleeve slides out under the action of gravity. The helical teeth and the helical column mesh to form a self-locking mechanism. This realizes a double locking structure with hydraulic drive for pre-locking of the main wedge block and spring push for secondary reinforcement of the secondary wedge block. Combined with the mechanical self-locking of the helical teeth and the helical column, it effectively resists the risk of hydraulic device failure and ensures stable support in complex environments, achieving rapid deployment and precise locking of the outriggers.

[0025] 2. In this utility model, rotating the external knob drives the worm gear to rotate, and then the meshing of the worm gear and worm wheel drives the connecting shaft for fine adjustment. The scale line at the top of the scale shaft can accurately display the adjustment angle. When the pressing column is pressed, the fourth spring is compressed, the pressing block slides up and presses the concave plate, causing the third spring to retract. The gimbal can be rotated for coarse adjustment. After releasing the pressing column, the fourth spring returns to its original position, and the concave plate re-locks the receiving block under the action of the third spring. Through the large transmission ratio characteristics of the worm gear and worm wheel and the precise cooperation with the scale shaft, the gimbal angle can be finely adjusted to meet the high-precision positioning requirements of surveying instruments. With the help of the elastic pre-tightening and locking mechanism of the spring assembly, the gimbal can be quickly switched between coarse and fine adjustment states and locked securely.

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0035] Example: A surveying device mounting bracket, as shown in the following example. Figures 1 to 3 It includes a base 1, with multiple telescopic mechanisms 2 rotatably connected to the bottom of the base 1, and an adjustment mechanism 3 installed inside the base 1;

[0036] The telescopic mechanism 2 includes an outer sleeve 21, which provides limiting and guiding functions for the piston 22. The tops of multiple outer sleeves 21 are rotatably connected to the bottom of the base 1. The base 1 and the outer sleeves 21 are connected via a universal joint connector, allowing for adaptation to different terrains. The piston 22 is slidably connected inside the outer sleeve 21. When the piston 22 is compressed by air, it pushes the middle sleeve 23 to extend slowly and simultaneously compresses it towards the top of the hydraulic pipe 25. The middle sleeve 23 is slidably connected inside the outer sleeve 21, providing limiting and guiding functions for the inner sleeve 29. The telescopic mechanism 2 is externally equipped with… An airbag 24 is provided, which allows the operator to press to inject air into the outer sleeve 21, causing the piston 22 to slide. A hydraulic pipe 25 is fixedly connected inside the middle sleeve 23. The hydraulic pipe 25 has a dedicated oil groove inside and a main wedge block 26 is slidably connected inside the hydraulic pipe 25. When the hydraulic oil inside the hydraulic pipe 25 is squeezed, it can push the main wedge block 26 to slide out and engage with the inner wall of the outer sleeve 21. A spring 27 is fixedly connected to the inner wall of the main wedge block 26. The spring 27 has an elastic function and provides elastic support for the secondary wedge block 28.

[0037] Specifically, the base 1 is rotatably connected to multiple telescopic mechanisms 2 via universal joint connectors at its bottom, which can adapt to different terrains. In the telescopic mechanism 2, the outer sleeve 21 provides a limiting guide for the piston 22. By pressing the airbag 24 to pump air into the tube, the piston 22 is pushed to slowly extend the middle sleeve 23 and squeeze the hydraulic pipe 25. After the hydraulic oil in the hydraulic pipe 25 is squeezed, it pushes the main wedge block 26 to extend and engage with the inner wall of the outer sleeve 21. The spring 27 on the inner wall of the main wedge block 26 provides elastic support for the secondary wedge block 28.

[0038] Reference Figures 2 to 4A secondary wedge block 28 is fixedly connected to the bottom of spring 27. Simultaneously, when the main wedge block 26 moves to the appropriate position, the inner wall of the middle sleeve 23 releases pressure on the secondary wedge block 28, allowing it to slide out under the elastic action of spring 27 and engage with the inner wall of the outer sleeve 21, forming a secondary fixation. This effectively prevents hydraulic oil leakage and improves stability. An inner sleeve 29 is slidably connected inside the middle sleeve 23. The inner sleeve 29 provides fixation and support for the helical teeth 2101. Multiple self-locking components 210 are fixedly connected to the inner wall of the inner sleeve 29. Each self-locking component 210 includes a helical tooth 2101, which can... When the sleeve 29 slides down under gravity, it can engage with the inclined column 2103 and lock itself in place, thus completing the fixation and strengthening the fixation effect. The left side of multiple inclined teeth 2101 is fixedly connected to the inner wall of the inner sleeve 29. The inner sleeve 29 provides fixation and support for the inclined teeth 2101. The inner wall of the middle sleeve 23 is fixedly connected to two springs 2102. The springs 2102 have elasticity and provide elastic support for the inclined column 2103. The right side of the two springs 2102 is fixedly connected to the inclined column 2103. When it is necessary to release the self-locking, the operator can release the limit of the inclined teeth 2101 by pulling the inclined column 2103 outward.

[0039] Specifically, when the main wedge block 26 is in place, the secondary wedge block 28 extends under the action of spring 27 and is fixed to the inner wall of the outer sleeve 21 for the second time to prevent hydraulic oil leakage and improve stability. The inner sleeve 29 inside the middle sleeve 23 is provided with a self-locking component 210. When the inner sleeve 29 slides down, the helical tooth 2101 engages with the helical column 2103 on the inner wall of the middle sleeve 23 for self-locking. To release the self-locking, the helical column 2103 can be pulled. In addition, the middle sleeve 23 guides the inner sleeve 29, while the inner sleeve 29 supports and fixes the helical tooth 2101. Spring 2102 provides elastic support for the helical column 2103.

[0040] Reference Figures 5 to 7The adjusting mechanism 3 includes a receiving block 31, which is externally located inside the base 1. The upper sub-wedge block 28 can be coarsely adjusted in position via the four sets of receiving blocks 31 at the bottom. The inner wall of the receiving block 31 is provided with two 90-degree rotating wheels. The base 1 has two limiting grooves 32 inside, which provide fixation and support for the spring 33. The spring 33 is fixedly connected to the rear inner wall of one of the limiting grooves 32. The spring 33 has an elastic function and its tail is a concave plate. 34 provides elastic support. A concave plate 34 is fixedly connected to the front side of spring 33. The concave plate 34 can receive the elastic support from spring 33 to push the concave plate 34 to slide and limit the receiving block 31 to prevent it from moving. A pressing column 35 is slidably connected inside the base 1. The operator can press the pressing column 35 to drive the squeezing block 37 to slide upward. A spring 4 36 is sleeved on the outside of the pressing column 35. The spring 4 36 has an elastic function and provides elastic support for the pressing column 35.

[0041] A pressing block 37 is fixedly connected to the top of the pressing column 35. During its upward sliding motion, the pressing block 37 presses against the concave plate 34, which in turn presses against the spring 33, causing it to retract and release the limiting position on the receiving block 31. This allows the operator to rotate the pan-tilt head 38. The pan-tilt head 38 is fixedly connected to the top of multiple receiving blocks 31, providing support for the surveying instrument. A scale axis 39 is rotatably connected to the top of the pan-tilt head 38, supporting the damping shaft 310. The damping shaft 310 provides installation space for the internal fine-tuning component 311. The damping shaft 310 is internally connected to a fine-tuning component 311, which includes a worm gear 3111. The operator can rotate the worm gear 3111 by turning an external knob. The external worm gear 3111 is externally connected to the inside of the damping shaft 310, which provides support for the worm gear 3111. The top of the scale shaft 39 is fixedly connected to a connecting shaft 3112, which is used to connect an external surveying instrument. The external of the connecting shaft 3112 is fixedly connected to a worm wheel 3113, which can receive force from the worm gear 3111 and rotate for fine-tuning. Fine-tuning can be performed through the scale lines at the bottom.

[0042] Specifically, the receiving block 31 is located inside the base 1. The rotating wheel cooperates with the limiting groove 32 inside the base 1. The limiting structure is formed by the spring 33 and the concave plate 34. When the pressing column 35 is pressed down, it drives the pressing block 37 to press the concave plate 34, causing the spring 33 to retract and release the limiting of the receiving block 31, making it convenient to rotate the gimbal 38 for coarse position adjustment. The top of the gimbal 38 is provided with a scale shaft 39, which is connected to the damping rotating shaft 310. The fine adjustment component 311 is installed inside. The fine adjustment component 311 includes a worm gear 3111. Rotating the external knob can drive the worm gear 3111 to rotate and mesh with the worm wheel 3113 on the connecting shaft 3112 to realize the fine adjustment of the surveying instrument angle. The scale lines on the scale shaft 39 provide a precise reference for fine adjustment. At the same time, the damping rotating shaft 310 ensures the stability of the fine adjustment process and prevents the surveying instrument from shaking. The entire adjustment mechanism 3 can realize the flexible adjustment and precise positioning of the surveying device fixing frame to meet different surveying needs.

[0043] Reference Figure 1 , Figure 2 and Figure 5 The outer surface of the main wedge block 26 contacts the inner wall of the outer sleeve 21. The main wedge block 26 is compressed by hydraulic oil, causing it to slide and engage with the corresponding groove in the outer sleeve 21, thus limiting and fixing it. The outer surface of the secondary wedge block 28 is slidably connected to the inside of the main wedge block 26. The main wedge block 26 provides limiting and guiding functions for the secondary wedge block 28. The outer surface of the inclined column 2103 is engaged with the inclined tooth 2101. Through engagement, the inclined column 2103 can form a self-locking mechanism under the gravity of its inclined tooth 2101. The outer surface of the inclined column 2103 is slidably connected to the inside of the middle sleeve 23. The middle sleeve 23 provides limiting and guiding functions for the inclined column 2103. The outer surface of the concave plate 34 is slidably connected to the inner wall of the outer sleeve 21. Inside the slot 32, the limiting slot 32 provides a limiting and guiding function for the concave plate 34. The top of the pressing block 37 contacts the inner wall of the concave plate 34. The pressing block 37 slides upward under the force from the pressing column 35, thereby pressing the concave plate 34 and releasing the limiting function of the receiving block 31. The outer side of the worm 3111 and the outer side of the worm wheel 3113 are meshed. Through meshing, the connecting shaft 3112 can be rotated, thereby achieving the effect of fine adjustment. The top of the spring 36 is fixedly connected to the inner wall of the base 1. The base 1 provides a fixing and supporting function for the spring 36. The bottom of the spring 36 is fixedly connected to the bottom inner wall of the pressing column 35. The spring 36 provides elastic support for the pressing column 35.

[0044] Specifically, the main wedge block 26 is squeezed by hydraulic oil and engages with the groove on the inner wall of the outer sleeve 21 to achieve a limit position. The secondary wedge block 28 inside it pops out after the main wedge block 26 is in place, providing secondary reinforcement. Inside the middle sleeve 23, the inclined column 2103 and the inclined tooth 2101 mesh to form a gravity self-locking. The middle sleeve 23 guides the inclined column 2103. Inside the limiting groove 32 of the base 1, the concave plate 34 is supported by the spring 33 to limit the receiving block 31. The pressing column 35 can release the limit position by pressing the concave plate 34 through the pressing block 37. In the fine adjustment component 311, the worm 3111 meshes with the worm wheel 3113 to drive the connecting shaft 3112 to rotate and achieve angle fine adjustment. The spring 4 36 connects the base 1 and the pressing column 35, providing a reset elastic support for the pressing column 35. All components work together to achieve stable and flexible adjustment of the device.

[0045] The implementation principle of this application embodiment is as follows: During use, pressing the airbag 24 drives air into the outer sleeve 21, and then the air pressure pushes the piston 22 to slide. The piston 22 squeezes the hydraulic oil in the hydraulic pipe 25, pushing the main wedge block 26 to extend and engage with the groove on the inner wall of the outer sleeve 21, thus achieving initial fixation. After the middle sleeve 23 is in place, the main wedge block 26 releases the compression of the secondary wedge block 28, and the spring 27 pushes the secondary wedge block 28 into the inner wall of the outer sleeve 21, forming secondary fixation. At the same time, the piston 22 pushes the middle sleeve 23 to extend slowly, and the inner sleeve 29 slides out under the action of gravity. The helical tooth 2101 and the helical column 2103 engage to form a self-locking mechanism, completing the fixation of the inner sleeve 29. Through the dual locking of hydraulic and mechanical means, hydraulic oil leakage is effectively prevented, and stability is improved. When it is necessary to retract, the helical column 2103 is pulled outward to release the self-locking mechanism.

[0046] When fine-tuning of the upper gimbal 38 is required, the external knob is rotated to drive the worm gear 3111 to rotate. Then, the meshing of the worm gear 3111 and the worm wheel 3113 drives the connecting shaft 3112 to make fine adjustments. The scale line on the top of the scale shaft 39 can accurately display the adjustment angle, achieving high-precision positioning. When the pressing column 35 is pressed, the spring 36 is compressed, the pressing block 37 slides up to press the concave plate 34, causing the spring 33 to retract and release the limit on the receiving block 31. At this time, the gimbal 38 can be rotated for coarse adjustment. After releasing the pressing column 35, the spring 36 returns to its original position, and the concave plate 34, under the action of the spring 33, re-locks the receiving block 31, locking the position. The preload provided by the elastic action of the worm wheel 3113, worm gear 3111 and spring ensures the adjustment accuracy and stability.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
