Description

Technical Field

[0001] The present invention relates to the technical field of engineering surveying and mapping, and particularly to an engineering surveying and mapping device based on remote sensing surveying and mapping technology. Background Art

[0002] Engineering surveying and mapping devices based on remote sensing surveying and mapping technology are widely used in terrain surveying, engineering monitoring, resource investigation and other fields in engineering construction. Classified by the carrying platform, they can be divided into ground remote sensing platforms, space remote sensing platforms and aerial remote sensing platforms. Among them, the ground remote sensing platform mainly consists of a multi-legged bracket and ground remote sensing instruments. The ground remote sensing instruments include surveying and mapping equipment such as optical remote sensing devices, microwave remote sensing devices and electromagnetic remote sensing devices.

[0003] Currently, for the anti-collision protection of the ground remote sensing instruments in the idle state on the engineering surveying and mapping device, an anti-collision protection mechanism is mostly configured on it. However, the existing surveying and mapping devices cannot directly use the original structures that must be provided on them as the anti-collision protection mechanism, resulting in the necessity to additionally design and adapt the anti-collision protection mechanism, which is not conducive to simplifying the structure of the surveying and mapping device and reducing its cost. Summary of the Invention

[0004] In view of this, the present invention provides an engineering surveying and mapping device based on remote sensing surveying and mapping technology to solve the problem that the existing surveying and mapping devices cannot directly use the original structures that must be provided on them as the anti-collision protection mechanism, resulting in the necessity to additionally design and adapt the anti-collision protection mechanism.

[0005] The technical solution proposed by the present invention is: an engineering surveying and mapping device based on remote sensing surveying and mapping technology, specifically including a holding frame and a ground remote sensing surveying instrument. The ground remote sensing surveying instrument is arranged on the holding frame to slide vertically up and down. Four long strip support frames are rotatably connected to the outside of the holding frame in a cross-shaped symmetry. Two positioning pressure plates are slidably installed in the middle parts of the two laterally symmetric long strip support frames in a spring-pushing manner. The bottom of the ground remote sensing surveying instrument is fixedly connected with a mounting seat. When the ground remote sensing surveying instrument is in an idle state, its body and the mounting seat slide down and are hidden in the shielding space formed by the four vertically retracted long strip support frames. When the long strip support frames are positioned in the vertically retracted state, the two positioning pressure plates are in top-pressure contact with the mounting seat that has slid down into the shielding space.

[0006] Furthermore, the long strip support frame is jointly composed of two symmetrically arranged support long shafts, a longitudinally installed plate welded between the top parts of the two support long shafts, and I-shaped connectors and oval-shaped limit sleeves respectively welded to the upper and lower ends of the two support long shafts. The I-shaped connectors are rotatably connected with the holding frame. A U-shaped sliding frame is welded to the outside of the positioning pressing plate, and a rubber pad is adhesively fixed to the inside. The U-shaped sliding frame is in sliding fit with the longitudinally arranged mounting plate. There are two springs for pushing the positioning pressing plate, and they are respectively sleeved on the two long side shafts of the U-shaped sliding frame. The springs are compressed and clamped between the longitudinally arranged mounting plate and the positioning pressing plate.

[0007] Furthermore, the mounting seat is composed of two horizontally bearing plates, one large and one small, up and down, and four vertical support plates symmetrically welded between the two horizontally bearing plates. When the positioning pressing plate abuts against the mounting seat, the rubber pad is squeezed onto the upper horizontal bearing plate.

[0008] Furthermore, a synchronous sliding frame is slidably installed on the outside of the holding frame. There are four tie rods rotatably connected between the synchronous sliding frame and the four I-shaped connecting pieces. Both the holding frame and the synchronous sliding frame are octagonal structures; A vertical holding plate is welded to the bottom of an inclined side plate of the synchronous sliding frame. A U-shaped mounting frame is jointly welded to the bottom ends of the inclined side plate and the vertical holding plate. A positioning insertion shaft is slidably installed through the U-shaped mounting frame and the vertical holding plate in the form of spring pushing. Two positioning holes are vertically spaced and penetrated through an inclined side wall of the holding frame. The protruding part of the first end of the positioning insertion shaft is selectively inserted and matched with the two positioning holes.

[0009] Furthermore, a U-shaped mounting frame is welded to the outside of an inclined side wall of the holding frame. A positioning insertion rod is slidably installed through the U-shaped mounting frame in the form of spring pushing; In the use state, the ground remote sensing mapping instrument slides out of the holding frame and is positioned and held above the holding frame. In this state, the upper horizontal bearing plate and the four vertical support plates slide into the holding frame following the ground remote sensing mapping instrument.

[0010] Furthermore, the shape of the horizontal bearing plate is adapted to that of the holding frame, and the vertical support plates are arranged in a twisted and inclined manner. When the upper horizontal bearing plate and the four vertical support plates slide into the holding frame, the four vertical support plates are correspondingly slidably attached to the inner sides of the four inclined side walls of the holding frame, and at the same time, the outer edge of the horizontal bearing plate is slidably attached to the inner side of the side wall of the holding frame; A positioning insertion hole is penetrated through the bottom end part of one of the vertical support plates. When the vertical support plate slides into the holding frame, the first end part of the positioning insertion rod passes through the inclined side wall of the holding frame and is inserted and matched with the positioning insertion hole.

[0011] Furthermore, two T-shaped sliding strips are symmetrically welded at the middle positions on the inner sides of the two symmetrically arranged straight side plates of the synchronous sliding frame, and two T-shaped sliding grooves are symmetrically opened at the middle positions on the outer sides of the two symmetrically arranged straight side walls of the holding frame. The two T-shaped sliding strips are correspondingly slidably matched with the two T-shaped sliding grooves.

[0012] Furthermore, taper-point support legs are slidably installed between the two support major axes on each long-strip support frame, and the taper-point support legs are in sliding fit through the waist-oval-shaped limit sleeve; A tightening bolt is installed through the middle position of the waist-oval-shaped limit sleeve in a threaded manner, and the head end of the tightening bolt is in pressing contact with the taper-point support leg.

[0013] An engineering surveying device based on remote sensing mapping technology provided by the present invention has the following beneficial effects: First, when the four feet swing outward and are in an inclined unfolded state, they can be inserted into the ground to support the ground remote sensing mapping instrument in contact with the ground; the taper-point support legs can slide telescopically along the waist-oval-shaped limit sleeve to adjust the length of each foot, so that the length of each foot can be increased or decreased according to the undulation of the terrain, and the ground remote sensing mapping instrument can be stably supported on the uneven ground for use, improving the flexibility of the surveying device and its compatibility with different terrains.

[0014] Second, the four pull rods, the four long-strip support frames, and the synchronous sliding frame together form a four-crank slider mechanism. Through this four-crank slider mechanism, swinging any one of the long-strip support frames inward or outward can drive the synchronous sliding frame to slide up and down, and control the four long-strip support frames to swing up and down synchronously to synchronously retract and expand the four feet. This can save the trouble of having to sequentially perform the retraction and expansion switching of the four feet step by step, and helps to improve the operation efficiency of the retraction and expansion switching of the four-foot bracket.

[0015] Third, when the ground remote sensing mapping instrument is in an idle state, its body and the mounting base slide down and are hidden in the shielding space formed by the four vertically retracted long-strip support frames. At this time, the four vertically retracted long-strip support frames can fence and protect the ground remote sensing mapping instrument from collision, reducing the probability of being damaged by impact when the ground remote sensing mapping instrument is transferred in an idle state; the four long-strip support frames can not only be used to stably support the ground remote sensing mapping instrument, but also be used to protect the idle ground remote sensing mapping instrument from collision, having the use effect of one device with two functions. This effect enables the present invention, compared with the prior art, to use the four originally necessary long-strip support frames on the surveying device as a protection mechanism for protecting the ground remote sensing mapping instrument from collision, which can save the trouble of having to additionally design and adapt a protection mechanism on the surveying device, helps to simplify the structure of the surveying device, and reduces its cost.

[0016] IV. When the long strip support frame swings, retracts, expands, it can drive two parts to move synchronously through two positioning pressure plates, and control the two positioning pressure plates to contact or separate from the mounting seat, so as to press-lock and release-unlock the ground remote sensing mapping instrument. This can save the trouble of manually locking and unlocking the ground remote sensing mapping instrument every time it is idle and protected, which helps to simplify the locking and unlocking steps of the ground remote sensing mapping instrument during idle protection, and the operation is convenient and efficient.

The head end of the pull rod 202 is rotatably connected to the short U-shaped connecting frame 201 at the corresponding position, and the tail end is rotatably connected to the long U-shaped connecting frame 4021 at the corresponding position; a vertical holding plate 205 is welded to the bottom of an inclined side plate of the synchronous sliding frame 2. A U-shaped mounting frame 203 is jointly welded to the bottom parts of the inclined side plate and the vertical holding plate 205. A positioning insertion shaft 204 is slidably mounted through the U-shaped mounting frame 203 and the vertical holding plate 205 in the form of spring pushing. Two positioning holes 104 are vertically spaced and penetrated through an inclined side wall of the holding frame 1. The protruding part of the head end of the positioning insertion shaft 204 is selectively inserted and matched with the two positioning holes 104; the positioning insertion shaft 204 is in sliding fit with the vertical side plate of the U-shaped mounting frame 203 and the vertical holding plate 205. A retaining ring 2041 is welded and sleeved on the positioning insertion shaft 204. The spring for pushing the positioning insertion shaft 204 is sleeved on the positioning insertion shaft 204 and is compressed and clamped between the retaining ring 2041 and the vertical side plate of the U-shaped mounting frame 203. The retaining ring 2041 abuts against the vertical holding plate 205.

[0026] Preferably, a U-shaped mounting frame 102 is welded to the outside of an inclined side wall of the holding frame 1. A positioning insertion rod 103 is slidably mounted inside the U-shaped mounting frame 102 in a manner of being pushed by a spring. A retaining ring 1031 is welded and sleeved on the positioning insertion rod 103. The positioning insertion rod 103 is slidably and penetratingly engaged with the vertical side plates of the U-shaped mounting frame 102. The spring that pushes the positioning insertion rod 103 is sleeved on the positioning insertion rod 103 and is compressed and clamped between the retaining ring 1031 and the vertical side plates of the U-shaped mounting frame 102. The retaining ring 1031 abuts against the inclined side wall of the holding frame 1. In the use state, the ground remote sensing mapping instrument 3 slides out of the holding frame 1 and is positioned and held above the holding frame 1. In this state, the upper horizontal bearing plate 3011 and the four vertical support plates 3012 slide into the holding frame 1 following the ground remote sensing mapping instrument 3.

[0027] Preferably, the horizontal bearing plate 3011 is adapted to the shape of the holding frame 1. The vertical support plates 3012 are arranged in a torsionally inclined manner. When the upper horizontal bearing plate 3011 and the four vertical support plates 3012 slide into the holding frame 1, the four vertical support plates 3012 are slidably and correspondingly attached to the inner sides of the four inclined side walls of the holding frame 1. At the same time, the outer edge of the horizontal bearing plate 3011 is slidably attached to the inner side of the side wall of the holding frame 1. A positioning insertion hole 3013 is formed through the bottom end portion of one vertical support plate 3012. When the vertical support plate 3012 slides into the holding frame 1, the leading end portion of the positioning insertion rod 103 passes through the inclined side wall of the holding frame 1 and is inserted and engaged with the positioning insertion hole 3013.

[0028] Preferably, two T-shaped sliding strips 206 are symmetrically welded to the middle positions on the inner sides of the two straight side plates symmetrically arranged on the synchronous sliding frame 2.

Two longitudinal positioning strips 106 are symmetrically welded to the middle upper positions on the two straight side walls symmetrically arranged on the holding frame 1. When the two retaining strips 2061 slide upward, they correspondingly abut against the two longitudinal positioning strips 106.

[0029] Preferably, a tapered tip support leg 5 is slidably mounted between the two support long shafts 401 on each long strip support frame 4. The tapered tip support leg 5 is slidably and penetratingly engaged with an oval-shaped limiting sleeve 403. A tightening bolt 4031 is penetratingly mounted in the middle position of the oval-shaped limiting sleeve 403 in a manner of being screwed. The leading end of the tightening bolt 4031 abuts against the tapered tip support leg 5.

[0030] The working principle, specific details, implementation steps, functions and interrelationships of each feature, and the roles played in the process of implementing the present technical solution will be elaborated and explained in detail below: The long support frame 4 and the tapered support legs 5 that slide with it together form a retractable support leg. The four long support frames 4 and the tapered support legs 5 together form a four-legged bracket for stably supporting the ground remote sensing mapping instrument 3. When the four legs are swung outward and placed in an inclined and unfolded state, they can be inserted into the ground to provide ground support for the ground remote sensing mapping instrument 3; the tapered support legs 5 can be telescopically slid along the waist-shaped limit sleeve 403 to adjust the length of each leg so that the length of each leg can be increased or decreased according to the unevenness of the terrain, so that the ground remote sensing mapping instrument 3 can be supported stably and balanced on uneven ground, thereby improving the flexibility of use of the surveying and mapping device and its compatibility with different terrains; the tightening bolts 4031 can tighten and fix the tapered support legs 5 so that the tapered support legs 5 remain at the height position after sliding adjustment.

[0031] The four pull rods 202, the four long support frames 4, and the synchronous sliding frame 2 are connected together to form a set of four-crank slider mechanisms. Through the four-crank slider mechanism, the inward and outward swinging of any long support frame 4 can drive the synchronous sliding frame 2 to slide up and down, and control the four long support frames 4 to swing up and down synchronously, and synchronously retract and extend the four legs. This can save the trouble of switching the four legs in steps and helps to improve the operational efficiency of the retraction and extension switching of the four-legged bracket; when the surveying and mapping device is in an idle state, the four-legged bracket is placed in a retracted form. When the four four-legged brackets are placed in a retracted form, the volume of the surveying and mapping device in the idle state can be reduced, which is convenient for transferring and storing the surveying and mapping device; when the positioning plug shaft 204 is plugged into the two positioning holes 104, the synchronous sliding frame 2 can be positioned in an upward sliding high position or a downward sliding low position, and the four legs can be kept in an inclined and extended or upright retracted posture.

[0032] When the ground remote sensing mapping instrument 3 is in an idle state, its body and the mounting seat 301 slide down and are hidden in the shielded space formed by the four upright and retracted long support frames 4. At this time, the four upright and retracted long support frames 4 can enclose the ground remote sensing mapping instrument 3 for anti-collision protection, thereby reducing the chance of the ground remote sensing mapping instrument 3 being damaged by collision when it is transferred in an idle state; the four long support frames 4 can be used to stably support the ground remote sensing mapping instrument 3, and can also be used to protect the ground remote sensing mapping instrument 3 in an idle state from collision, thus having a dual-purpose use effect. Compared with the prior art, this effect enables the present invention to utilize the four original and necessary long support frames 4 on the surveying and mapping device as a protective mechanism for anti-collision protection of the ground remote sensing mapping instrument 3, thereby eliminating the trouble of having to design an additional adaptive protective mechanism on the surveying and mapping device, thereby helping to simplify the structure of the surveying and mapping device and reduce its cost.

[0033] When the positioning rod 103 is plugged into the positioning socket 3013 , the ground remote sensing mapping instrument 3 can be positioned in an upward sliding and protruding use state.

[0034] When the long strip support frame 4 is positioned in the erected and contracted state, the two positioning pressure plates 404 are in top-pressure abutting contact with the mounting base 301 that has slid down into the shielding space. And when the positioning pressure plate 404 is in top-pressure abutting contact with the mounting base 301, the rubber pad 4042 is squeezed onto the upper horizontal bearing plate 3011. This can perform extrusion positioning on the mounting base 301 and fix and hold the ground remote sensing surveying instrument 3 in the shielding space, avoiding the lack of necessary fixing and limiting measures for the ground remote sensing surveying instrument 3 in the idle state, and driving the mounting base 301 to slide and shift along the four erected guide shafts 101 during the transfer process, resulting in sliding impact contact between the mounting base 301 and the holding frame 1 and causing impact shock damage to its body. Moreover, it can also prevent the ground remote sensing surveying instrument 3 from slipping out of the shielding space, causing the surrounding protection effect implemented by the four long strip support frames 4 to fail; when the long strip support frame 4 swings and expands or contracts, it can drive the two parts to move synchronously through the two positioning pressure plates 404, and control the top-pressure contact or separation between the two positioning pressure plates 404 and the mounting base 301, performing top-pressure locking and unlocking on the ground remote sensing surveying instrument 3. This can save the trouble of manually locking and unlocking the ground remote sensing surveying instrument 3 additionally every time it is idly protected, helping to simplify the locking and unlocking steps of the ground remote sensing surveying instrument 3 during idle protection, and the operation is convenient and efficient; when the positioning pressure plate 404 is in top-pressure abutting contact with the mounting base 301, the longitudinally arranged mounting plate 4011 compresses the spring on the U-shaped sliding frame 4041 through the driving force of the inward swing of the long strip support frame 4, and transmits the inward swing driving force of the long strip support frame 4 to the positioning pressure plate 404 and the rubber pad 4042 through this spring, enabling the positioning pressure plate 404 and the rubber pad 4042 to lock the ground remote sensing surveying instrument 3 in the idle state by using this inward swing driving force.

[0035] It should be noted that: the installation, debugging, surveying working principle and use operation steps of the ground remote sensing surveying instrument 3 are prior art for the surveyors using it, so they will not be elaborated here.

[0036] In this article, the following points need to be noted: 1. The attached drawings of the embodiments of the present invention only relate to the structures involved in the embodiments of the present invention, and other structures can refer to the general design.

[0037] 2. Without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0038] The above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
