Description

Technical Field

[0001] This invention relates to the field of surveying devices for building engineering, specifically a surveying device for building engineering with a stable structure. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, building construction refers to engineering projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] Existing surveying equipment used in construction engineering relies on three sets of hinged support legs to support the surveying instrument during surveying operations. However, each of the three sets of support legs is manually extended one by one by the staff, which may result in inconsistent extension angles. When the surveying instrument is placed and supported by the support legs, the center of gravity shifts due to the different extension angles of the support legs, making the equipment prone to tilting and tipping over. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a surveying device for building engineering with a stable structure, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a surveying device for building engineering with a stable structure, including a workbench, a support leg hinged to the bottom of the workbench, a support base fixed to the top of the support leg, a protective plate detachably installed on the top of the support base, a surveying instrument detachably installed on the top of the support base, an extension device for simultaneously extending and supporting the support leg on the workbench, and a protective device for shielding the surveying instrument on the workbench; The expansion device includes a motor, a threaded rod, a threaded sleeve, a hinged rod, a bending block, a return spring, a rotating shaft, a torsion spring, a limiting block, a disc, and a rotating block. The motor is fixed to the top of the worktable, the threaded rod is fixed to the bottom output end of the motor, the disc is fixed to the bottom of the threaded rod, the threaded sleeve is threaded to the outer wall of the threaded rod, one end of the hinged rod is hinged to the side wall of the support frame, and the other end of the hinged rod is hinged to the outer wall of the threaded sleeve. When the drive motor is started, the threaded rod rotates forward, which drives the threaded sleeve to move upward. The threaded rod drives the threaded sleeve to move upward, pressing the hinged rod and causing it to rotate at the hinge point. The hinged rod can then push the support leg to unfold.

[0006] According to the above technical solution, the bending block is slidably installed on the inner side of the support leg, one side of the return spring is fixed to the inner side of the support leg, and the other side of the return spring is fixed to the side wall of the bending block.

[0007] According to the above technical solution, the rotating shaft is rotatably installed on the inner side of the support leg, the limiting block is fixed on the outer wall of the rotating shaft, the rotating block is fixed on the outer wall of the rotating shaft, one side of the torsion spring is fixed on the inner side of the support leg, and the other side of the torsion spring is fixed on the side wall of the rotating block. When the support leg is unfolded, the bending block will not be subjected to the squeezing force. The return spring can make the bending block squeeze the rotating block, so that the rotating shaft drives the limiting block to rotate.

[0008] According to the above technical solution, the protective device includes a squeezing block, a side baffle, an L-shaped connecting block, a circular ring, a positive baffle, a fixing block, a connecting spring, a transmission block, an air storage box, a piston plate, a piston rod, a return spring, an inclined block, and an airbag; the squeezing block is fixed to the inner side of the support leg, the side baffle passes through the workbench and the support base, and is slidably connected at the passage, the L-shaped connecting block is fixed to the side wall of the side baffle, and the circular ring is fixed to the side of the L-shaped connecting block away from the side baffle.

[0009] According to the above technical solution, the positive baffle is fixed to the outer wall of the side baffle, the transmission block is fixed to the top of the side baffle, the fixing block is fixed to the side wall of the side baffle, one side of the connecting spring is fixed to the top of the fixing block, and the other side of the connecting spring is fixed to the inner side of the support seat. When the support leg rotates, it can drive the pressing block to rotate without pressing the ring. Because the connecting spring is in a compressed state, it can cause the side baffle to move downward, thereby driving the positive baffle to move downward.

[0010] According to the above technical solution, the gas storage box is fixed to the bottom of the protective plate, the piston plate is slidably installed on the inner wall of the gas storage box, the piston rod is fixed to the side wall of the piston plate, the piston rod passes through the side wall of the gas storage box and is slidably connected at the penetration point, the inclined block is fixed to the end point of the piston rod, one side of the return spring is fixed to the side wall of the inclined block, the other side of the return spring is fixed to the side wall of the gas storage box, and an airbag is fixed to the bottom of the gas storage box. The airbag is connected to the gas storage box. When the side baffle moves downward, the transmission block will not squeeze the inclined block. Because the return spring is in a compressed state, the return spring will drive the piston rod and piston plate to reset.

[0011] According to the above technical solution, a stabilizing device is provided inside the workbench. The stabilizing device includes an L-shaped block, a compression ring, an auxiliary spring, a stabilizing plate, and a moving plate. One end of the L-shaped block is fixed to the side wall of the side baffle, and the compression ring is fixed to the other end of the L-shaped block.

[0012] According to the above technical solution, the stabilizing plate passes through the workbench and fits snugly at the penetration point. The moving plate is slidably installed on the inner wall of the workbench. One side of the auxiliary spring is fixed to the inner side of the workbench, and the other side of the auxiliary spring is fixed to the side wall of the moving plate. When the side baffle moves upward, it can drive the L-shaped block to move upward, which can cause the compression ring to squeeze the inclined surface of the moving plate. This will cause the moving plate to be subjected to compression force, which can drive the stabilizing plate to move out of the workbench. Thus, when the equipment is not in use and is tilted, the stabilizing plate will contact the ground and insert into the soil.

[0013] This invention provides a surveying device for building engineering with a stable structure. It has the following beneficial effects: 1. This invention, by setting up an extension device, allows the threaded rod to move upwards via the motor when the equipment needs to be used. The hinge rod enables the support legs to unfold synchronously, ensuring consistent unfolding angles and solving the problem of tipping caused by inconsistent unfolding angles. Furthermore, when the support legs unfold, the bending block is moved away from the disc, preventing it from being compressed. Through the cooperation of the return spring, rotating block, and rotating shaft, the rotating shaft drives the limiting block to unfold, thus achieving a limiting effect. This prevents the support legs, whose ends are typically conical, from sinking when inserted into the soil. The limiting block ensures contact with the ground, preventing the support legs from sinking.

[0014] 2. This invention incorporates a protective device. When the support legs are retracted, the compression block presses against the ring, causing the side baffle to move upwards. Simultaneously, the front baffle moves upwards, allowing the side and front baffles to shield the surveying instrument. This solves the problem of the surveying instrument being damaged by collisions during transport when not in use. Furthermore, when the side baffle moves upwards, the transmission block moves upwards, pressing against the inclined surface of the inclined block. Through the cooperation of the piston rod and piston plate, the gas in the gas storage box is compressed into the air bladder, causing the air bladder to expand and press against the surveying instrument, thus pressing the surveying instrument firmly and preventing it from shaking on the equipment during transport.

[0015] 3. By setting up a stabilizing device, when the side baffle moves upward, it can drive the L-shaped block to move upward, which can cause the compression ring to squeeze the inclined surface of the moving plate. This will cause the moving plate to be subjected to compression force, which can drive the stabilizing plate to move out of the worktable. Thus, when the equipment is not in use and it is tilted, the stabilizing plate will contact the ground and insert into the soil to stabilize the equipment. This prevents the equipment from being displaced and rolled due to inertia when it is tilted on the ground, which could easily cause damage to the equipment by rolling and impacting back and forth.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 One embodiment of the present invention is: a surveying device for building engineering with a stable structure, including a workbench 1, a support leg 2 hinged to the bottom of the workbench 1, three sets of support legs 2 are provided, and the bottom of the workbench 1 is arranged in a circular array, a support base 3 is fixed to the top of the support leg 2, and a protective plate 4 is detachably installed on the top of the support base 3. The protective plate 4 can shield and protect the top of the surveying instrument 5. The surveying instrument 5 is detachably installed on the top of the support base 3. An extension device is provided on the workbench 1 to allow the support legs to be extended and supported at the same time. The extension device includes a motor 61, a threaded rod 62, a threaded sleeve 64, a hinge rod 63, a bending block 65, a return spring 66, a rotating shaft 67, a torsion spring 610, a limiting block 68, a disc 611, and a rotating block 69. The motor 61 is fixed to the top of the worktable 1, the threaded rod 62 is fixed to the bottom output end of the motor 61, the disc 611 is fixed to the bottom of the threaded rod 62, the threaded sleeve 64 is threaded to the outer wall of the threaded rod 62, and one end of the hinge rod 63 is hinged to the side wall of the support frame. The other end of 3 is hinged to the outer wall of the threaded sleeve 64. The bending block 65 is slidably installed on the inner side of the support leg 2. One side of the return spring 66 is fixed to the inner side of the support leg 2, and the other side of the return spring 66 is fixed to the side wall of the bending block 65. The rotating shaft 67 is rotatably installed on the inner side of the support leg 2. The limiting block 68 is fixed to the outer wall of the rotating shaft 67. The rotating block 69 is fixed to the outer wall of the rotating shaft 67. One side of the torsion spring 610 is fixed to the inner side of the support leg 2, and the other side of the torsion spring 610 is fixed to the side wall of the rotating block 69.

[0020] When the equipment needs to be used, starting the motor 61 can cause the threaded rod 62 to drive the threaded sleeve 64 to move upward. Through the hinge rod 63, the support legs 2 can be deployed synchronously, so that the deployment angle of the support legs 2 is consistent, thus solving the problem of tipping caused by inconsistent deployment angle of the support legs 2. There are three sets of limiting blocks 68, and the three sets of limiting blocks 68 are arranged in a circular array with the center point of the workbench 1 as the center. When the support leg 2 is unfolded, the bending block 65 will move away from the disc 611, so that the bending block 65 is not squeezed. Through the cooperation of the return spring 66, the rotating block 69 and the rotating shaft 67, the rotating shaft 67 can drive the limiting block 68 to unfold, thereby achieving the limiting effect. This prevents the end of the support leg 2, which is generally conical, from sinking when inserted into the soil due to the soft soil. The limiting block 68 can contact the ground to prevent the support leg 2 from sinking.

[0021] In this embodiment, during operation: When the surveying equipment needs to be used, the equipment carries the surveying location. When in use, the motor 61 is started, controlling the threaded rod 62 to rotate forward. This causes the threaded sleeve 64 to move upward on the threaded rod 62. When the threaded sleeve 64 moves upward, it presses against the hinge rod 63, causing the hinge rod 63 to rotate at the hinge point. When the hinge rod 63 rotates, it presses against the support legs 2, causing them to rotate as well. This allows all three sets of support legs 2 to unfold simultaneously. When the support legs 2 are unfolded, they are placed on the ground to support the surveying operation. When the support leg 2 is extended, the bending block 65 is no longer under pressure due to the compression of the return spring 66, causing the bending block 65 to move out of the support leg 2. This causes the end of the bending block 65 to press against the rotating block 69, causing the rotating block 69 to rotate. This, in turn, drives the rotating shaft 67 to rotate, causing the limiting block 68 to rotate out of the support leg 2. Since the elastic coefficient of the return spring 66 is five times that of the torsion spring 610, when the bending block 65 presses against the rotating block 69 to rotate, the rotating block 69 can cause the torsion spring 610 to be compressed and deformed.

[0022] After the survey is completed, the motor 61 is started to control the threaded rod 62 to reverse, which causes the threaded sleeve 64 to move downward on the threaded rod 62. The threaded sleeve 64 pulls the hinge rod 63, causing the hinge rod 63 to rotate at the hinge point. This pulls the three sets of support legs 2 to retract. When the support legs 2 retract, the bending block 65 is pressed against the disc 611, causing the bending block 65 to move inward into the support leg 2. This compresses the return spring 66. When the bending block 65 moves inward into the support leg 2, it does not press the rotating block 69. Because the torsion spring 610 is in a compressed state, the torsion spring 610 drives the rotating shaft 67 to rotate, causing the limit block 68 to rotate into the support leg 2.

[0023] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a protective device for shielding the surveying instrument 5 is provided on the workbench 1. The protective device includes a pressing block 71, a side baffle 72, an L-shaped connecting block 73, a ring 74, a front baffle 77, a fixing block 75, a connecting spring 76, a transmission block 78, an air storage box 79, a piston plate 710, a piston rod 713, a return spring 711, an inclined block 712, and an airbag 714. The pressing block 71 is fixed to the inner side of the support leg 2. The side baffle 72 passes through the workbench 1 and the support base 3 and is slidably connected at the passage. The L-shaped connecting block 73 is fixed to the side wall of the side baffle 72. The ring 74 is fixed to the side of the L-shaped connecting block 73 away from the side baffle 72. The front baffle 77 is fixed to the outer wall of the side baffle 72. The transmission block 78 is fixed to the outer wall of the side baffle 72. The top of the side baffle 72 is fixed, the fixing block 75 is fixed to the side wall of the side baffle 72, one side of the connecting spring 76 is fixed to the top of the fixing block 75, and the other side of the connecting spring 76 is fixed to the inner side of the support base 3. The air storage box 79 is fixed to the bottom of the protective plate 4. The piston plate 710 is slidably installed on the inner wall of the air storage box 79. The piston rod 713 is fixed to the side wall of the piston plate 710 and passes through the side wall of the air storage box 79, and the passage is slidably connected. The inclined block 712 is fixed to the end of the piston rod 713. One side of the return spring 711 is fixed to the side wall of the inclined block 712, and the other side of the return spring 711 is fixed to the side wall of the air storage box 79. An airbag 714 is fixed to the bottom of the air storage box 79 and communicates with the air storage box 79.

[0024] Furthermore, when the support leg 2 is retracted, the compression block 71 will compress the ring 74, thereby compressing the side baffle 72 to move upward, and at the same time driving the front baffle 77 to move upward, so that the side baffle 72 and the front baffle 77 can block the surveying instrument 5, thus solving the problem that the surveying instrument 5 is damaged by collision when carried when not in use. Furthermore, when the side baffle 72 moves upward, it will cause the transmission block 78 to move upward, which will cause the transmission block 78 to squeeze the inclined surface of the inclined block 712. Through the cooperation of the piston rod 713 and the piston plate 710, the gas in the gas storage box 79 can be squeezed into the air bag 714, causing the air bag 714 to expand and squeeze onto the surveying instrument 5, thereby pressing the surveying instrument 5 tightly and preventing the surveying instrument 5 from shaking on the equipment when it is being carried.

[0025] The workbench 1 is equipped with a stabilizing device, which includes an L-shaped block 91, a compression ring 92, an auxiliary spring 94, a stabilizing plate 93, and a moving plate 95. One end of the L-shaped block 91 is fixed to the side wall of the side baffle 72, the compression ring 92 is fixed to the other end of the L-shaped block 91, the stabilizing plate 93 passes through the workbench 1 and fits snugly at the penetration point, the moving plate 95 is slidably installed on the inner wall of the workbench 1, one side of the auxiliary spring 94 is fixed to the inner side of the workbench 1, and the other side of the auxiliary spring 94 is fixed to the side wall of the moving plate 95.

[0026] Multiple sets of stabilizing plates 93 are arranged in a circular array with the center point of the workbench 1 as the center. When the side baffle 72 moves upward, it can drive the L-shaped block 91 to move upward, which can cause the compression ring 92 to squeeze the inclined surface of the moving plate 95. This will cause the moving plate 95 to be subjected to compression force, which can drive the stabilizing plates 93 to move out of the workbench 1. So when the equipment is not in use and it is tilted, the stabilizing plates 93 will contact the ground and insert into the soil to stabilize the equipment. This prevents the equipment from being displaced and rolled due to inertia when it is tilted on the ground, which could easily cause damage to the equipment by rolling and impacting back and forth.

[0027] In this embodiment, when the support leg 2 is extended, the compression block 71 rotates, preventing it from compressing the bottom of the ring 74. Because the connecting spring 76 is compressed, it causes the fixing block 75 and the side baffle 72 to move downwards. At the same time, the side baffle 72 causes the front baffle 77 to move downwards, thus exposing the surveying instrument 5 for surveying operations. When the side baffle 72 moves downwards, it can drive the transmission block 78 to move downwards, preventing it from compressing the inclined block 712. The return spring 711 is compressed, allowing it to reset the inclined block 712 and the piston rod 713. This allows the piston plate 710 to draw the gas from the airbag 714 into the air storage box 79, preventing the airbag 714 from compressing the surveying instrument 5. When the support leg 2 is retracted, the compression block 71 rotates and compresses the bottom of the ring 74, causing the ring 74 to move upward. This causes the L-shaped connecting block 73 to move upward. When the L-shaped connecting block 73 moves upward, it causes the side baffle 72 and the front baffle 77 to move upward, thus shielding and protecting the sides and front of the surveying instrument 5. When the side baffle 72 moves upward, the transmission block 78 compresses the inclined surface of the inclined block 712, causing the inclined blocks 712 to be compressed and move closer to each other. This causes the piston rod 713 to move into the air storage box 79, and the piston plate 710 to push the gas in the air storage box 79 into the airbag 714, causing the airbag 714 to expand and press against the top of the surveying instrument 5, thus pressing and fixing the surveying instrument 5. When the side baffle 72 moves upward, it causes the L-shaped block 91 to move upward, which in turn causes the compression ring 92 to move upward. When the compression ring 92 moves upward and contacts the inclined surface of the moving plate 95, the moving plate 95 is subjected to compression force, moving away from the motor 61 and stretching the auxiliary spring 94. When the moving plate 95 moves, it can move the stabilizing plate 93 out of the worktable 1. When the side baffle 72 moves downward to use the surveying instrument 5, it can move the L-shaped block 91 and the compression ring 92 downward, preventing the compression ring 92 from squeezing the inclined surface of the moving plate 95. With the cooperation of the auxiliary spring 94, the moving plate 95 and the stabilizing plate 93 can be moved into the worktable 1, preventing the stabilizing plate 93 from being extended during operation, which would make it inconvenient for the operator to use the surveying instrument 5.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
