Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying and mapping, in particular to a shock-absorbing platform for engineering surveying and mapping. Background Technique

[0002] Surveying and mapping refers to the measurement, collection and mapping of the shape, size, spatial position and its attributes of natural geographical elements or surface artificial facilities for the planning and design of engineering construction and administrative management. The existing surveying and mapping generally is carried out on a fixed platform. When it comes to mobile surveying and mapping, the machine will vibrate, resulting in poor surveying and mapping accuracy.

[0003] After retrieval, the patent application with the Chinese patent publication number CN217382337U discloses an adjustable shock-absorbing platform for engineering surveying and mapping, which mainly realizes the shock-absorbing effect during mobile surveying and mapping by setting a tripod, springs, a platform and sliding rods.

[0004] Comparing with the prior art in the related field, it can be known that traditional shock-absorbing platforms mostly adopt conventional shock-absorbing elements such as simple springs and rubbers, and simply rely on absorbing and buffering shock energy to reduce the impact of vibration. The shock-absorbing effect is limited and it is difficult to meet the strict requirements of high-precision engineering surveying and mapping for vibration control. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shock-absorbing platform for engineering surveying and mapping to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A shock-absorbing platform for engineering surveying and mapping includes a base, on which a stability-maintaining unit for offsetting the shock force is installed. A support plate is fixedly installed on the stability-maintaining unit, and the stability-maintaining unit is fixedly installed on the support plate. The stability-maintaining unit is fixedly connected to an installation platform, and an installation unit for fixing a surveying instrument is fixedly installed on the installation platform;

[0008] The stability-maintaining unit includes a turntable, which is rotatably installed on the base. The first strut and the second strut are rotatably arranged on the turntable. The inclination directions of the first strut and the second strut are opposite. The upper ends of the first strut and the second strut are rotatably installed with sliding connectors. The lower surface of the support plate is fixedly installed with a first guide rail and a second guide rail. The first guide rail is slidably connected to the sliding connector on the first strut, and the second guide rail is slidably connected to the sliding connector on the second strut. A horizontal damping mechanism is rotatably installed on the support plate and a vertical damping mechanism is fixedly installed. The horizontal damping mechanism is inclined and rotatably connected to the sliding connector. The vertical damping mechanism is fixedly installed on the support plate, and the upper end of the vertical damping mechanism is fixedly connected to the installation platform. An adjusting component is fixedly installed on the support plate and the turntable.

[0009] Furthermore, the adjusting component includes an adjusting screw rod and a rotating seat. The rotating seat is fixedly installed on the upper surface of the turntable. The lower end of the adjusting screw rod is rotatably connected to the rotating seat, and the adjusting screw rod is installed on the support plate through threaded fit.

[0010] Furthermore, both the vertical damping mechanism and the horizontal damping mechanism include a hydraulic cylinder body and a movable part. The hydraulic cylinder body of the vertical damping mechanism is fixedly installed on the support plate, and the movable part of the vertical damping mechanism is fixedly installed on the mounting table. The hydraulic cylinder body of the horizontal damping mechanism is rotatably installed on the lower surface of the support plate. The movable part of the horizontal damping mechanism is rotatably connected to the sliding connecting part. The hydraulic cylinder body is hermetically and slidably connected to the movable part. A cross beam and a perforated plate arranged in a fixed pattern are fixedly arranged in the hydraulic cylinder body. The movable part is slidably connected to the cross beam.

The bidirectional screw rod is rotatably installed on the mounting table. Knobs are fixedly installed at the ends of the bidirectional screw rod. Mounting seats are threadedly connected to the opposite threads at both ends of the bidirectional screw rod. The mounting seats are slidably connected to the mounting table.

[0012] Furthermore, a spirit level is fixedly installed on the upper surface of the support plate.

[0013] Furthermore, a screw telescopic leg mechanism is fixedly installed on the lower surface of the base. The lower end of the screw telescopic leg mechanism is rotatably installed with a bottom plate.

[0014] Furthermore, an anti-slip and shock-absorbing pad is fixedly installed on the lower surface of the bottom plate.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] During the support process of the surveying instrument, the vibration acting force is dispersed and converted into horizontal and vertical forces by using the turntable, the first support rod and the second support rod, avoiding the concentrated impact of the acting force during use. Then, the flow resistance of the hydraulic oil caused by the perforated plates in the horizontal damping mechanism and the vertical damping mechanism is used to reduce the influence of the vibration force on the stability of the entire mounting table, improve the stability of the support for the surveying instrument, effectively reduce the influence of vibration on the surveying instrument, protect the instrument and improve the measurement accuracy and service life.

Detailed implementation manners

[0026] As Figures 1-6As shown in the figure, a shock-absorbing platform for engineering surveying and mapping includes a base 1. A stability-maintaining unit for offsetting seismic forces is installed on the base 1. A support plate 5 is fixedly installed on the stability-maintaining unit. The stability-maintaining unit is fixedly installed on the support plate 5. The stability-maintaining unit is fixedly connected to an installation platform 2. An installation unit for fixing surveying instruments is fixedly installed on the installation platform 2. When measuring, the entire platform is placed on the site where it is needed, and the surveying instruments are fixedly installed on the installation platform 2 through the installation unit. During the surveying process, the external vibrations are dispersed and offset through the stability-maintaining unit to provide shock-absorbing protection for the surveying instruments and reduce the damage to the surveying instruments caused by vibrations;

[0027] As Figures 1-6As shown in the figure, the stability maintenance unit includes a turntable 303, which is rotatably installed on the base 1. The turntable 303 has two components, an inner part and an outer part, which are rotationally connected. Both parts of the turntable 303 are rotationally connected to the base 1. The first support rod 304 and the second support rod 305 are rotationally arranged on the turntable 303. The first support rod 304 is connected to the outer ring part of the turntable 303, and the second support rod 305 is connected to the inner ring part of the turntable 303. The inclination directions of the first support rod 304 and the second support rod 305 are opposite. The upper ends of the first support rod 304 and the second support rod 305 are rotatably installed with sliding connectors 308. The lower surface of the support plate 5 is fixedly installed with a first guide rail 306 and a second guide rail 307. The first guide rail 306 is located outside the second guide rail 307. The first guide rail 306 is slidably connected to the sliding connector 308 on the first support rod 304, and the second guide rail 307 is slidably connected to the sliding connector 308 on the second support rod 305. A horizontal damping mechanism 309 is rotatably installed on the support plate 5, and a vertical damping mechanism 310 is fixedly installed. The horizontal damping mechanism 309 is inclined, and the horizontal damping mechanism 309 is arranged at an inclined angle with the sliding connector 308. The horizontal damping mechanism 309 is rotationally connected to the sliding connector 308. The vertical damping mechanism 310 is fixedly installed on the support plate 5, and the upper end of the vertical damping mechanism 310 is fixedly connected to the installation platform 2. An adjustment component is fixedly installed on the support plate 5 and the turntable 303. By adjusting the distance between the support plate 5 and the turntable 303 through the adjustment component, the inclination angles of the first support rod 304 and the second support rod 305 are adjusted, so that the first support rod 304 and the second support rod 305 maintain the best force dispersion and conduction state, thereby better buffering. During the process of the platform supporting the measuring instrument, when the base 1 is subjected to an external force, the base 1 transmits the vibration force to the turntable 303. Since the first support rod 304 and the second support rod 305 are inclined, the turntable 303 is subjected to the force to push the first support rod 304 and the second support rod 305 to rotate in opposite directions. The first support rod 304 and the second support rod 305 respectively push the sliding connector 308 to slide along the first guide rail 306 and the second guide rail 307. When the sliding connector 308 moves, it squeezes the horizontal damping mechanism 309. Through the turntable 303, the first support rod 304, the second support rod 305, and the sliding connector 308, the vibration force is dispersed to different horizontal damping mechanisms 309, so that the vibration force is converted into horizontal and vertical forces. By dispersing the force, the impact caused by the concentrated force is reduced. The horizontal damping mechanism 309 buffers and cancels the dispersed force. The remaining force acts on the vertical damping mechanism 310 through the support plate 5. The vertical damping mechanism 310 buffers and cancels the remaining force again, improving the buffering effect, thereby effectively reducing the impact of vibration on the surveying instrument during the surveying process, protecting the instrument, and improving the measurement accuracy and service life, so that the entire platform better supports the surveying instrument.

[0028] As Figure 1 , Figure 2 shown, the adjusting assembly includes an adjusting screw rod 301 and a rotating seat 302. The rotating seat 302 is fixedly installed on the upper surface of the turntable 303. The rotating seat 302 is rotatably connected to the lower end of the adjusting screw rod 301. The adjusting screw rod 301 is installed on the support plate 5 through threaded cooperation. Since the rotating seat 302 and the adjusting screw rod 301 are rotatably connected, the adjusting screw rod 301 will not affect the rotation of the rotating seat 302 and the turntable 303. The turntable 303 and the support plate 5 are supported and limited by the adjusting screw rod 301 and the rotating seat 302. At the same time, by rotating the adjusting screw rod 301, the connection length between the adjusting screw rod 301 and the support plate 5 is changed, so that the distance between the support plate 5 and the turntable 303 is changed, thereby adjusting the inclination angles of the first support rod 304 and the second support rod 305, so that the first support rod 304 and the second support rod 305 maintain the best force dispersion and conduction state, so as to better carry out shock absorption.

[0029] As Figures 1-5As shown, both the vertical damping mechanism 310 and the horizontal damping mechanism 309 include a hydraulic cylinder body 3005 and a movable member 3001. The hydraulic cylinder body 3005 of the vertical damping mechanism 310 is fixedly installed on the support plate 5, and the movable member 3001 of the vertical damping mechanism 310 is fixedly installed on the mounting table 2. The hydraulic cylinder body 3005 of the horizontal damping mechanism 309 is rotatably installed on the lower surface of the support plate 5. The movable member 3001 of the horizontal damping mechanism 309 is rotatably connected to the sliding connecting member 308. The hydraulic cylinder body 3005 is hermetically and slidably connected to the movable member 3001. A cross beam 3003 is fixedly arranged in the hydraulic cylinder body 3005, and orifice plates 3004 are fixedly arranged in an array. The movable member 3001 is slidably connected to the cross beam 3003. A sealing piston is installed on the part of the movable member 3001 located inside the hydraulic cylinder body 3005. The sealing piston is slidably connected inside the hydraulic cylinder body 3005. A spring 3002 is sleeved on the movable member 3001 between the sealing piston and the cross beam 3003. The apertures of the arranged orifice plates 3004 decrease in sequence. Hydraulic oil is installed in the hydraulic cylinder body 3005. When the platform is subjected to a vibration force during use, the movable member 3001 is forced to drive the sealing piston to move. The sealing piston squeezes the spring 3002 and pushes and squeezes the hydraulic oil in the hydraulic cylinder body 3005. The hydraulic oil in the hydraulic cylinder body 3005 flows through the orifice plates 3004 with different apertures. According to the principle of fluid mechanics, the smaller the aperture of the orifice plate 3004, the greater the resistance to the flow of the hydraulic oil. The hydraulic oil needs to overcome a greater resistance when passing through the orifice plate 3004. This resistance will consume the energy of the sliding rod to push the top plate, converting mechanical energy into heat energy during the flow of the hydraulic oil, thereby generating a blocking effect. Through the blocking force generated during the flow of the hydraulic oil, the vertical damping mechanism 310 and the horizontal damping mechanism 309 buffer and offset the received vibration, reduce the impact of the vibration on the surveying and mapping instrument, improve the shock absorption effect. At the same time, during use, the elastic force of the spring 3002 can reset the sealing piston and the movable member 3001.

[0030] As Figure 1 , Figure 6 shown, the installation unit includes a bidirectional lead screw 401. The thread directions at both ends of the bidirectional lead screw 401 are opposite. The bidirectional lead screw 401 is rotatably installed on the mounting table 2. Knobs are fixedly installed at the ends of the bidirectional lead screw 401. Mounting seats 402 are threadedly connected to the opposite threads at both ends of the bidirectional lead screw 401. The mounting seats 402 are slidably connected to the mounting table 2. According to the different surveying and mapping instruments to be used, by rotating the knob to rotate the bidirectional lead screw 401, the mounting seats 402 are driven by the bidirectional lead screw 401 to move, adjusting the distance between the two mounting seats 402, so as to facilitate the installation and use of different surveying and mapping instruments, and improve the convenience and versatility of the platform during use.

[0031] As Figure 1 , Figure 2As shown, a spirit level 6 is fixedly installed on the upper surface of the support plate 5. By detecting the levelness of the support plate 5 with the spirit level 6, the levelness during the use of the platform can be adjusted, so as to perform measurement better.

[0032] As Figure 1 、 Figure 6 shown, a screw telescopic leg mechanism 7 is fixedly installed on the lower surface of the base 1. The lower end of the screw telescopic leg mechanism 7 is rotatably installed with a bottom plate 8. The base 1 is supported by the screw telescopic leg mechanism 7 and the bottom plate 8 to improve the stability of the base 1. The screw telescopic leg mechanism 7 includes a sleeve and a screw. By adjusting the connection length between the sleeve and the screw, the support height of the screw telescopic leg mechanism 7 is adjusted. By adjusting the support height of the screw telescopic leg mechanism 7, the levelness of the base 1 is adjusted.

[0033] As Figure 1 、 Figure 6 shown, an anti-slip and shock-absorbing pad 9 is fixedly installed on the lower surface of the bottom plate 8. The anti-slip property of the bottom plate 8 is improved through the anti-slip and shock-absorbing pad 9, thereby improving the stability of the entire platform when placed and used. And the bottom plate 8 is shock-absorbed through the anti-slip and shock-absorbing pad 9 to reduce the vibration received by the bottom plate 8.

[0034] Working principle: As Figure 1 、 Figure 6 shown, place the entire platform in the site where it is needed. According to the surveying and mapping instrument to be used, rotate the bidirectional lead screw 401 through the knob. Drive the mounting seat 402 to move through the bidirectional lead screw 401, adjust the distance between the two mounting seats 402, and fixedly install the surveying and mapping instrument on the mounting seat 402 to complete the installation of the surveying and mapping instrument;

[0035] As Figure 1 、 Figure 2 、 Figure 6 shown, detect the levelness of the support plate 5 with the spirit level 6, adjust the support height of the screw telescopic leg mechanism 7, thereby adjusting the levelness of the base 1. The anti-slip and shock-absorbing pad 9 and the bottom plate 8 improve the stability of the base 1 when placed and supported;

[0036] As Figures 1-6As shown, when an external force acts on the base 1, the base 1 conducts the vibration force to the turntable 303. Since the first support rod 304 and the second support rod 305 are inclined, the turntable 303 is pushed by the force to cause the first support rod 304 and the second support rod 305 to deflect and rotate in opposite directions. The first support rod 304 and the second support rod 305 respectively push the sliding connector 308 to slide along the first guide rail 306 and the second guide rail 307. When the sliding connector 308 moves, it squeezes the lateral damping mechanism 309. Through the turntable 303, the first support rod 304, the second support rod 305, and the sliding connector 308, the vibration force is dispersed to different lateral damping mechanisms 309. The lateral damping mechanism 309 cushions and cancels the dispersed force, and the remaining force acts on the vertical damping mechanism 310 through the support plate 5. The vertical damping mechanism 310 cushions and cancels the remaining force again to prevent the vibration from affecting the support stability of the installation table 2.

[0037] As Figures 1-5 shown, when the lateral damping mechanism 309 and the lateral damping mechanism 309 are subjected to a force, the movable part 3001 is driven by the force to drive the sealing piston to move. The sealing piston squeezes the spring 3002 and pushes and squeezes the hydraulic oil in the hydraulic cylinder body 3005. The hydraulic oil in the hydraulic cylinder body 3005 flows through the orifice plates 3004 with different apertures. The orifice plates 3004 with different apertures block the hydraulic oil, and through the resistance force generated when the hydraulic oil flows, the vertical damping mechanism 310 and the lateral damping mechanism 309 cushion and cancel the received vibration.

[0038] At the same time, as Figure 1 , Figure 2 shown, during the use of the platform support, rotate the adjusting screw rod 301 to change the connection length between the adjusting screw rod 301 and the support plate 5, so that the distance between the support plate 5 and the turntable 303 changes, thereby adjusting the inclination angles of the first support rod 304 and the second support rod 305, enabling the first support rod 304 and the second support rod 305 to better conduct the force, and thus improving the support stability of the installation table 2.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
