Description

Technical Field

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

[0002] Engineering surveying and mapping devices based on remote sensing mapping technology are widely used in topographic mapping, engineering monitoring, resource surveys and other fields in engineering construction. According to the classification of the carrying platform, they can be divided into ground remote sensing platforms, space remote sensing platforms and aviation remote sensing platforms. Among them, the ground remote sensing platform is mainly composed of a multi-legged bracket and ground remote sensing instruments. The ground remote sensing instruments include optical remote sensing devices, microwave remote sensing devices, electromagnetic remote sensing devices and other surveying and mapping equipment.

[0003] Current engineering surveying and mapping equipment provides anti-collision protection for idle ground remote sensing instruments, and most of them are equipped with anti-collision protection mechanisms. However, the existing surveying and mapping equipment cannot directly utilize the original structure that must be set up on it as the anti-collision protection mechanism, so it is necessary to additionally design and adapt the anti-collision protection mechanism, which is not conducive to simplifying the structure of the surveying and mapping equipment 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 mapping technology to solve the problem that existing surveying and mapping devices cannot directly use the original structure that must be set up thereon as an anti-collision protection mechanism, resulting in the need for additional design and adaptation of 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 mapping technology, specifically comprising a holding frame and a ground remote sensing mapping instrument, wherein the holding frame is provided with a ground remote sensing mapping instrument that slides straight up and down;

[0006] The outer side of the retaining frame is rotatably connected to four long support frames in a cross-shaped symmetrical form, and the middle parts of the two long support frames symmetrically arranged in the transverse direction are slidably installed with two positioning pressure plates in the form of spring push; the bottom of the ground remote sensing mapping instrument is fixedly connected to a mounting seat, and when the ground remote sensing mapping instrument is in an idle state, its body and the mounting seat slide down and are hidden in the shielded space formed by the four upright and retracted long support frames; when the long support frame is positioned in the upright and retracted state, the two positioning pressure plates press against and contact the mounting seat that slides down into the shielded space.

[0007] Furthermore, the long support frame is composed of two symmetrically arranged support shafts, a longitudinal mounting plate welded between the top ends of the two support shafts, and an I-shaped connector and a waist-shaped limit sleeve respectively welded to the upper and lower ends of the two support shafts. The I-shaped connector is rotatably connected to the retaining frame.

[0008] A U-shaped sliding frame is welded to the outside of the positioning pressure plate, and a rubber pad is glued and fixed to the inside. The U-shaped sliding frame and the longitudinal mounting plate are slidably matched. There are two springs for pushing the positioning pressure plate, and they are respectively rotated on the two long side axes of the U-shaped sliding frame. The spring is compressed and clamped between the longitudinal mounting plate and the positioning pressure plate.

[0009] Furthermore, the mounting seat is composed of two horizontal bearing plates, one large and one small, and four vertical support plates symmetrically welded between the two horizontal bearing plates. When the positioning pressure plate is pressed against the mounting seat, the rubber pad is squeezed onto the upper horizontal bearing plate.

[0010] Furthermore, a synchronous sliding frame is slidably installed on the outside of the holding frame, and four pull rods are rotatably connected between the synchronous sliding frame and four I-shaped connecting pieces. The holding frame and the synchronous sliding frame are both octagonal structures.

[0011] An upright retaining plate is welded to the bottom of an inclined side plate of the synchronous sliding frame, and a U-shaped mounting frame is welded together with the bottom end portion of the inclined side plate and the upright retaining plate. A positioning plug shaft is slidingly installed between the U-shaped mounting frame and the upright retaining plate in the form of a spring push, and two positioning holes are opened on an inclined side wall of the retaining frame at upper and lower intervals, and the protruding part of the head end of the positioning plug shaft is selectively plugged into and matched with the two positioning holes.

[0012] Furthermore, a U-shaped mounting frame is welded to the outer side of an inclined side wall of the holding frame, and a positioning rod is slidably installed inside the U-shaped mounting frame in the form of a spring push;

[0013] When in use, the ground remote sensing mapping instrument slides up and protrudes from the retaining frame and is positioned and retained above the retaining frame. In this state, the upper horizontal supporting plate and four vertical support plates follow the ground remote sensing mapping instrument and slide up into the retaining frame.

[0014] Furthermore, the horizontal supporting plate is adapted to the shape of the holding frame, and the vertical supporting plates are twisted and tilted. When the upper horizontal supporting plate and the four vertical supporting plates slide into the holding frame, the four vertical supporting plates slide and fit in with the inner sides of the four inclined side walls of the holding frame, and at the same time, the outer sides of the horizontal supporting plate slide and fit in with the inner sides of the side walls of the holding frame.

[0015] A positioning hole is provided through the bottom end of one of the vertical support plates. When the vertical support plate slides into the retaining frame, the head end of the positioning rod passes through the inclined side wall of the retaining frame and engages with the positioning hole.

[0016] Furthermore, two T-shaped slides are symmetrically welded at the inner middle positions of the two symmetrically arranged straight side plates on the synchronous sliding frame, and two T-shaped slide grooves are symmetrically opened at the outer middle positions of the two symmetrically arranged straight side walls on the retaining frame, and the two T-shaped slides correspond to and slide with the two T-shaped slide grooves.

[0017] Furthermore, a conical support leg is slidably mounted between the two supporting long axes on each of the long support frames, and the conical support leg is slidably fitted with a waist-shaped limiting sleeve;

[0018] A tightening bolt is installed through the middle position of the waist-shaped limiting sleeve in the form of a threaded screw, and the head end of the tightening bolt is in pressing contact with the cone-tip supporting leg.

[0019] The invention provides an engineering surveying and mapping device based on remote sensing mapping technology, which has the following beneficial effects:

[0020] 1. 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 surveying and mapping instrument; the tapered support legs can be telescopically slid along the waist-shaped limit sleeve to adjust the length of each leg, so that the length of each leg can be increased or decreased according to the uneven terrain, so that the ground remote sensing surveying and mapping instrument 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.

[0021] 2. Four pull rods, four long support frames, and a synchronous sliding frame are connected together to form a four-crank slider mechanism. Through this four-crank slider mechanism, the inward and outward swing of any long support frame can drive the synchronous sliding frame to slide up and down, and control the four long support frames to swing up and down synchronously, and synchronously retract and extend the four legs. This can save the trouble of retracting and extending the four legs step by step, and help improve the operational efficiency of the retraction and extension switching of the four-legged bracket.

[0022] 3. 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 shielded space formed by the four upright and retracted long support frames. At this time, the four upright and retracted long support frames can enclose the ground remote sensing mapping instrument for anti-collision protection, thereby reducing the chance of the ground remote sensing mapping instrument being damaged by collision when being transferred in an idle state; the four long support frames can be used to stably support the ground remote sensing mapping instrument and to protect the ground remote sensing mapping instrument in an idle state, thus having a dual-purpose effect. Compared with the prior art, this effect enables the present invention to utilize the four original and necessary long support frames on the surveying and mapping device as a protective mechanism for anti-collision protection of the ground remote sensing mapping instrument, thereby eliminating the trouble of having to design an additional adaptive protective mechanism on the surveying and mapping device, helping to simplify the structure of the surveying and mapping device and reduce its cost.

[0023] 4. When the long support frame swings, retracts and extends, it can drive the two positioning pressure plates to move synchronously, and control the two positioning pressure plates to contact or separate with the mounting seat, so as to lock and release 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 protection, and help simplify the locking and unlocking steps of the ground remote sensing mapping instrument during idle protection, making the operation convenient and efficient.

[0054] Preferably, the horizontal supporting plate 3011 is adapted to the shape of the retaining frame 1, and the vertical support plate 3012 is twisted and tilted. When the upper horizontal supporting plate 3011 and the four vertical support plates 3012 slide into the retaining frame 1, the four vertical support plates 3012 slide and fit correspondingly with the inner sides of the four inclined side walls of the retaining frame 1, and at the same time, the outer edges of the horizontal supporting plate 3011 slide and fit with the inner sides of the side walls of the retaining frame 1; a positioning hole 3013 is penetrated through the bottom end portion of one vertical support plate 3012, and when the vertical support plate 3012 slides into the retaining frame 1, the head end portion of the positioning rod 103 passes through the inclined side wall of the retaining frame 1 and is plugged into the positioning hole 3013.

[0056] Preferably, a conical support leg 5 is slidably installed between the two supporting long axes 401 on each long support frame 4, and the conical support leg 5 is slidably fitted through the waist-shaped limiting sleeve 403; a tightening bolt 4031 is installed through the middle position of the waist-shaped limiting sleeve 403 in the form of a threaded screw, and the head end of the tightening bolt 4031 is pressed against the conical support leg 5.

[0057] The following is a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of the above features, as well as their role in implementing this technical solution:

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] When the long support frame 4 is positioned in the upright retracted state, the two positioning pressure plates 404 are pressed against the mounting seat 301 that has slid down into the shielded space, and when the positioning pressure plates 404 are pressed against the mounting seat 301, the rubber pads 4042 are squeezed on the horizontal supporting plate 3011 on the upper side, which can squeeze and position the mounting seat 301 and fix the ground remote sensing mapping instrument 3 in the shielded space, avoiding the lack of necessary fixed limiting measures for the ground remote sensing mapping instrument 3 in the idle state. During the transfer process, the mounting seat 301 is driven to slide along the four vertical guide shafts 101, causing the mounting seat 301 to slide and impact contact with the retaining frame 1, causing impact and vibration damage to its body, and also preventing the ground remote sensing mapping instrument 3 from sliding out of the shielded space, causing the four long support frames 4 to lose their protective effect; when the long support frame 4 is swung and retracted, it can drive the two positioning pressure plates 404 to press and contact with the mounting seat 301 By synchronously moving the two positioning pressure plates 404 and controlling the two positioning pressure plates 404 to press into contact or separate from the mounting seat 301, the ground remote sensing mapping instrument 3 is pressed and locked and released and unlocked. This can save the trouble of manually locking and unlocking the ground remote sensing mapping instrument 3 every time it is idle for protection, and helps to simplify the locking and unlocking steps of the ground remote sensing mapping instrument 3 when it is idle for protection, and the operation is convenient and efficient; when the positioning pressure plate 404 is pressed into contact with the mounting seat 301, the longitudinal mounting plate 4011 compresses the spring on the U-shaped sliding frame 4041 through the driving force of the inward swing of the long support frame 4, and transmits the inward swing driving force of the long support frame 4 to the positioning pressure plate 404 and the rubber pad 4042 through the spring, so that the positioning pressure plate 404 and the rubber pad 4042 can use the inward swing driving force to lock the ground remote sensing mapping instrument 3 in the idle state.

[0063] It is worth noting that the installation, debugging, surveying and mapping working principle and operation steps of the ground remote sensing surveying and mapping instrument 3 are existing technologies for surveyors who use it, so they will not be described in detail here.
