Description

Technical Field

[0001] The present invention relates to the technical field of archaeological equipment, and in particular to a movable device used for microscopic observation of on-site cultural relics. Background Art

[0002] There are a large number of cultural relics buried in ancient cultural sites and ancient tombs. Through excavation and exploration of ancient cultural sites and ancient tombs, precious ancient cultural relics can be discovered. When excavating ancient cultural relics, in order to improve the meticulousness of cultural relic excavation, microscopic observation equipment can be used to photograph and observe the excavation surface of the excavation pit. In the process of photographing and observing the excavation surface with microscopic observation equipment, the covering soil above the ancient cultural relics needs to be cleaned in time.

[0003] The core components of the existing movable device for microscopic observation of on-site cultural relics include a microscope, a support plate and a pallet. The microscope and the pallet are both arranged on the support plate. When cleaning and photographing the excavation surface, the excavators squat on the support plate, and use a brush to clean the excavation surface of the excavation pit while photographing and observing the excavation surface with a microscope. The pallet supports the excavators' arms to relieve the fatigue of their arms during long-term and meticulous cleaning work.

[0004] However, when using the above-mentioned movable device for on-site microscopic observation of cultural relics, when cleaning the excavation surface in the excavation pit and taking real-time photos and observations, although the support plate can be used to support the arms of the excavators to reduce the fatigue of the excavators' arms, when the excavators wave the brush to clean the excavation surface, the arm movements of the excavators will cause the support plate to vibrate, and the support plate will transmit the vibration to the microscope through the support plate. Since the microscope is very sensitive to vibrations in the working environment, large vibrations will cause the microscope to take blurred images, thereby affecting the clarity of the microscopic observation of the excavation surface, which is not conducive to the excavators' detailed observation of the details of the cultural relics.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 8 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 8 As shown, the movable device for microscopic observation of on-site cultural relics provided by the present invention includes a microscope 101, a bracket 102 and a longitudinal slide rail 103, wherein the longitudinal slide rail 103 is arranged on one side of the excavation pit 1 along the longitudinal direction of the excavation pit 1, and further includes: a support plate 105, a support plate 109, a pneumatic piston mechanism and a first elastic body 108, wherein the support plate 105 is arranged on one side of the microscope 101 along the transverse direction of the excavation pit 1, wherein the support plate 105 is connected to the longitudinal slide rail 103 through the bracket 102, and the support plate 105 is used to support the excavation personnel human body; the support plate 109 is horizontally arranged, and the support plate 109 is used to support the arms of the excavators; the pneumatic piston mechanism is vertically arranged on the support plate 105, and the pneumatic piston mechanism is connected with a pneumatic control circuit, the pneumatic piston mechanism is connected to the support plate 109, and the pneumatic piston mechanism is used to adjust the height of the support plate 109; the first elastic body 108 is arranged in the pneumatic piston mechanism, and when the pneumatic piston mechanism is inflated, the first elastic body 108 is in a compressed state, and the first elastic body 108 is used to alleviate the vibration of the support plate 109 in the vertical direction.

[0034] The working principle of the above embodiment is briefly described:

[0035] The support 102 is provided with a lifting mechanism 110, and the microscope 101 is fixed on the lifting mechanism 110. The lifting mechanism 110 is used to adjust the vertical height of the microscope 101. The support plate 105 is connected with a connecting rod 104, and the support plate is connected to the support 102 through the connecting rod 104. When in use, the longitudinal position of the support 102 along the excavation pit 1 is adjusted by the longitudinal slide rail 103, thereby adjusting the longitudinal position of the microscope 101 along the excavation pit 1, so as to perform microscopic observation on different positions of the excavation pit 1 along its longitudinal direction. In addition, since the support plate 105 is connected to the support 102 through the connecting rod 104, when the support 102 moves longitudinally along the excavation pit 1, it will drive the support plate 105 to move longitudinally along the excavation pit 1, thereby adjusting the longitudinal position of the support plate 105 along the excavation pit 1, and can always ensure that the relative position of the support plate 105 and the microscope 101 is constant. With the real-time microscopic shooting and observation of the excavation surface of the excavation pit 1 by the microscope 101, the excavation personnel can timely clean the covering soil of the excavation surface. When the excavator is cleaning the excavation surface below the microscope 101, the support plate 109 can support the excavator's arm, thereby applying a supporting force to the excavator's arm to prevent the excavator's arm from feeling tired during long-term cleaning work. And as the depth of the excavation pit 1 changes, the height of the pneumatic piston mechanism is adjusted by controlling the action of the pneumatic control circuit, thereby adjusting the height of the support plate 109 to adapt to the depth change of the excavation pit 1. When the excavator swings his arm to clean the excavation surface, the reciprocating shaking of the excavator's arm can drive the support plate 109 to reciprocate in the vertical direction. Since the gas in the pneumatic piston mechanism and the first elastic body 108 in a compressed state can effectively alleviate the vibration of the support plate, when the excavator is cleaning the covering soil of the excavation surface, the movement of the excavator's arm is prevented from causing the microscope 101 to vibrate, thereby ensuring the stability of the image captured by the microscope 101 and the clarity of the microscopic observation.

[0036] The movable device for on-site microscopic observation of cultural relics of the present invention can support the arms of excavators when using the microscope 101 to perform microscopic photography and observation on the excavation surface of the excavation pit 1, so as to reduce the fatigue of the excavators' arms after a long period of cleaning work. In the process of supporting the arms of the excavators, the arm movements of the excavators when cleaning the soil covering the upper side of the cultural relics are prevented from causing vibration of the microscope 101, thereby ensuring the stability of the real-time image captured by the microscope 101, thereby ensuring the clarity of the microscopic observation through the microscope 101.

[0037] On the basis of the above-mentioned embodiment, in order to prevent the excavator's arm from slipping off the support plate 109, the device is guaranteed to support the excavator's arm.

[0038] like Figure 2 , Figure 6 and Figure 7As shown, the pneumatic piston mechanism includes a cylinder body 106 and a first piston 107, the first cylinder body 106 is vertically arranged on the support plate 105, the first cylinder body 106 is connected to the air control circuit, the first piston 107 is slidably connected in the first cylinder body 106, the first elastic body 108 is arranged on the first piston 107, the first elastic body 108 abuts against the first piston 107, when the first cylinder body 106 is inflated, the first elastic body 108 is compressed by the first piston 107, the top of the support plate 109 is provided with a through-axis hole, the support plate 109 is pivotally connected to the top of the first piston 107 through the through-axis hole, and a locking mechanism 2 is provided at the through-axis hole, and the locking mechanism 2 is used to limit the rotation of the support plate 109 relative to the top of the first piston 107.

[0039] When cleaning the excavation surfaces at different depths, different volumes of air are filled into the first cylinder 106 of the pneumatic piston mechanism through the air control circuit, thereby driving the first piston 107 to move in the vertical direction. Under the action of the elastic force of the first elastic body 108, the height of the support plate 109 connected to the top of the first piston 107 can be adjusted to adapt to the cleaning work of the excavation surfaces at different depths. And because the first piston 107 connected to the support plate 109 is slidably connected in the first cylinder 106, when the excavator swings his arm to clean the excavation surface, under the coupling action of the first elastic body 108 and the gas in the first cylinder 106, the vibration of the first piston 107 can be more effectively alleviated, thereby effectively preventing the vibration of the first piston 107 from being transmitted to the first cylinder 106, thereby effectively preventing the movement of the excavator's arm from causing the microscope 101 to vibrate when the excavator cleans the soil covering the excavation surface. By rotating the support plate 109, the deflection angle of the support plate 109 in the horizontal plane relative to the length direction of the support plate 105, that is, the lateral direction of the excavation pit 1, can be adjusted to adjust the support plate 109 to a suitable direction to adapt to different arm postures of the excavator. After the deflection angle of the support plate 109 is adjusted, the support plate 109 and the top of the first piston 107 are locked by the locking mechanism 2, thereby preventing the support plate 109 from rotating when subjected to the pressure of the excavator's arm, thereby preventing the excavator's arm from slipping off the support plate 109, and ensuring the support function of the device for the excavator's arm.

[0040] As a preferred solution, Figure 2 and Figure 6-Figure 8As shown, the locking mechanism 2 includes a gear ring 301 and a gear block 302, the gear ring 301 is arranged on the inner wall of the through-shaft hole, the first piston 107 is provided with a vent hole 303, the top of the first piston 107 is provided with a piston cavity 304 along the radial direction of the gear ring 301, the bottom end of the vent hole 303 is connected with the inner cavity of the first cylinder body 106, the top of the vent hole 303 is connected with the piston cavity 304, the piston cavity 304 is slidably connected with a second piston 305, the gear block 302 is connected to the second piston 305, the gear block 302 can be gear-engaged with the gear ring 301, and the gear block 302 is used to limit the rotation of the support plate 109 relative to the first piston 107. When the air control circuit fills the inner cavity of the first cylinder 106 with gas, under the action of the elastic force of the first elastic body 108, the air pressure in the inner cavity of the first cylinder 106 increases, and the gas enters the piston cavity 304 through the vent hole 303, and then drives the second piston 305 to move out of the piston cavity 304, and the second piston 305 drives the gear block 302 to move out of the piston cavity 304 until the gear block 302 is engaged with the gear ring 301. At this time, the gear block 302 limits the rotation of the gear ring 301, thereby limiting the rotation of the support plate 109, thereby completing the locking of the deflection angle of the support plate 109 by the locking mechanism 2. When the support plate 109 needs to be rotated, the air control circuit is controlled to exhaust air from the inner cavity of the first cavity, the air pressure in the inner cavity of the first cavity is reduced, and the air pressure in the piston cavity 304 is reduced until the air pressure sucks the second piston 305 into the piston cavity 304, and the second piston 305 drives the gear block 302 away from the gear ring 301, thereby completing the unlocking of the locking mechanism 2. The pneumatic control circuit can adjust the height of the support plate 109 to support the excavator's arms when the excavator is cleaning the excavation surface of different depths in the excavation pit 1. When cleaning the excavation points in different directions in front of the support plate 109, the support plate 109 is rotated to adjust the angle of the support plate 109 to adapt to the arm posture of the excavator when cleaning the excavation points in different directions, and the angle of the support plate 109 is automatically locked after the height of the support plate 109 is adjusted, which can prevent the user's arm from rotating relative to the second piston 305 when waving, thereby preventing the excavator from missing and improving the safety of the device.

[0041] As a preferred solution, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a pedal 401 is provided on the support plate 105, the first cylinder body 106 is provided on the pedal 401, a second cylinder body 402 in a vertical direction is provided on the support plate 105, a third piston 403 is slidably connected in the second cylinder body 402, the third piston 403 is connected to the pedal 401, the second cylinder body 402 is connected to the air control circuit, a second elastic body 404 is provided on the third piston 403, the second elastic body 404 abuts against the third piston 403, and when the inner cavity of the second cylinder body 402 is inflated, the second elastic body 404 is compressed by the third piston 403. By setting the pedal 401 and the second cylinder 402, the air control circuit is controlled to enter or exhaust air from the second cylinder 402. When the inner cavity of the second cylinder 402 is inflated, the third piston 403 moves upward, and the second elastic body 404 is compressed, so that the vertical height of the third piston 403 can be adjusted, thereby adjusting the vertical height of the pedal 401, so as to clean and observe the excavation surface of different depths, thereby improving the adaptability of the device. When the excavation personnel clean and observe different positions in the excavation pit 1, they need to walk on the pedal 401, which will cause the pedal 401 to vibrate in the vertical direction. The vibration of the pedal 401 will drive the third piston 403 to vibrate in the vertical direction. The elastic body and gas in the second cylinder 402 will buffer the vibration of the third piston 403, thereby preventing the vibration from being transmitted to the microscope 101, thereby ensuring the stability of the picture taken by the microscope 101.

[0042] As a preferred solution, Figure 2 and Figure 5 As shown, the bottom end of the pedal 401 is provided with a slide bar 501 along the horizontal direction of the excavation pit 1, and the slide bar 501 is slidably connected with a first slider 502, and the first slider 502 is connected to the top of the third piston 403. The slide bar 501 is provided with a third elastic body 503, and the third elastic body 503 abuts against the first slider 502. The third elastic body 503 is used to buffer the vibration of the first slider 502 along the horizontal direction of the excavation pit 1. When the excavator walks on the pedal 401, the pedal 401 will not only vibrate in the vertical direction, but also vibrate in the horizontal direction of the excavation pit 1. The pedal 401 drives the slide bar 501 to vibrate in the horizontal direction of the excavation pit 1, and the first slider 502 vibrates in the horizontal direction of the excavation pit 1 relative to the slide bar 501. Since the third elastic body 503 abuts against the first slider 502, the third elastic body 503 can effectively buffer the vibration of the pedal 401, thereby further preventing the microscope 101 from vibrating.

[0043] As a preferred solution, Figure 2 and Figure 5As shown, the support plate 105 is also provided with a pressure sensor 6, and the end of the third elastic body 503 away from the first slider 502 abuts against the pressure sensor 6. The pressure sensor 6 is used to detect the real-time extrusion force value of the third elastic body 503. The pressure sensor 6 is electrically connected to a controller, and the controller is electrically connected to an alarm. The maximum pressure threshold is preset in the controller. The controller compares the real-time extrusion force value with the preset maximum pressure threshold. When the real-time extrusion force value is greater than the preset maximum pressure threshold, the controller controls the alarm to alarm. By setting the pressure sensor 6, when the excavator walks on the pedal 401, the pedal 401 vibrates, and the third elastic body 503 buffers the vibration of the pedal 401. The real-time extrusion force value of the third elastic body 503 changes reciprocatingly. When the peak value of the real-time extrusion force value of the third elastic body 503 is greater than the preset maximum pressure threshold, the alarm is controlled to alarm, thereby reminding the excavator to reduce the movement amplitude to prevent the pedal 401 from vibrating too much, thereby further preventing the microscope 101 from vibrating.

[0044] As a preferred solution, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the pedal 401 is provided with a slide groove 701 along the horizontal direction of the excavation pit 1, and a second slider 702 is slidably connected in the slide groove 701, and the second slider 702 is connected to the first cylinder 106. A retaining ring 703 is provided on the second slider 702, and the retaining ring 703 abuts against the upper edge of the slide groove 701. The retaining ring 703 is used to limit the second slider 702 to move in the vertical direction relative to the slide groove 701. By setting the slide groove 701 along the horizontal direction of the excavation, the first cylinder 106 slides in the slide groove 701 through the second slider 702, thereby changing the position of the microscope 101 along the horizontal direction of the excavation pit 1, so that the entire excavation surface can be observed microscopically, and the retaining ring 703 on the second slider 702 abuts against the upper edge of the slide groove 701, and the retaining ring 703 is used to limit the second slider 702 to move in the vertical direction, thereby preventing the second slider 702 from slipping out of the slide groove 701, thereby ensuring the normal operation of the entire device.

[0045] As a preferred solution, Figure 6 and Figure 8 As shown, the side wall of the first piston 107 is provided with a vertical limiting groove 801, and a limiting slider 802 is slidably connected in the limiting groove 801, and the limiting slider 802 is connected to the second slider 702, and the limiting slider 802 is used to limit the rotation of the first piston 107 relative to the first cylinder body 106. By providing the limiting groove 801 and the limiting slider 802, the limiting groove 801 and the limiting slider 802 are used to limit the rotation of the first piston 107, so that when the support plate 109 is at a high height, the support plate 109 is prevented from rotating, and the support plate 109 is guaranteed to support the arms of the excavator.

[0046] As a preferred solution, Figure 1-Figure 1 As shown, the longitudinal slide rail 103 is an electric slide rail, a guide rail 901 parallel to the longitudinal slide rail 103 is provided on one side of the excavation pit 1, a dovetail groove 902 along the longitudinal direction of the excavation pit 1 is provided on the guide rail 901, a dovetail tenon 903 is slidably connected in the dovetail groove 902, and the dovetail tenon 903 is connected to the support plate 105. By providing the guide rail 901 parallel to the longitudinal slide rail 103, the support plate 105 is slidably connected to the dovetail groove 902 on the guide rail 901 through the dovetail tenon 903, so that the support plate 105 is not directly connected to the longitudinal slide rail 103, thereby further preventing the vibration generated by the person walking on the support plate 105 from being transmitted to the microscope 101, ensuring the stability of the picture taken by the microscope 101, and the dovetail groove 902 and the dovetail tenon 903 have a certain degree of centering, which can ensure the stability of the support plate 105 moving along the longitudinal direction of the excavation pit 1.
