DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-Figure 10 , an engineering geological crack measuring device, including a mounting plate 1, a slide groove 2 is opened on the lower surface of the mounting plate 1, a first threaded rod 3 is horizontally rotatably installed in the slide groove 2, a slider 4 is threadedly sleeved on the first threaded rod 3, and a laser rangefinder 5 is fixedly installed at the bottom of the slider 4 (the laser rangefinder 5 generates laser inside the crack, and the laser hits the bottom of the crack and refracts back to the laser transceiver. The time from the emission to the reception of the laser beam is measured by a timer, and the depth of the crack is calculated, so that the depth of the crack can be measured. It belongs to the prior art and its working principle is not described in detail here). The surface of the slider 4 is in sliding contact with the groove wall of the slide groove 2, and the first threaded rod 3 is controlled to rotate by a driving assembly. The driving assembly includes a driving motor 11 fixedly installed on one side of the mounting plate 1, and the output shaft of the driving motor 11 penetrates into the slide groove 2 and is fixedly connected to one end of the first threaded rod 3. The lower surface of the mounting plate 1 is symmetrically provided with a support assembly around its own central vertical axis.

[0036] The supporting assembly includes two vertical plates 6 fixedly mounted on the lower surface of the mounting plate 1, a rotating rod 7 horizontally rotatingly mounted between the two vertical plates 6, and a supporting plate 8 fixedly sleeved on the rotating rod 7. The two rotating rods 7 are located on the same side. One end of each of the two rotating rods 7 passes through the vertical plate 6, and a threaded groove 9 is provided at one end of the rotating rod 7 passing through the vertical plate 6. Two second threaded rods 10 with opposite thread rotation directions are respectively threadedly mounted in the two threaded grooves 9. The two second threaded rods 10 are controlled to move together by a transmission component. The transmission component includes a third threaded rod 12 and a U-shaped plate 13 threadedly sleeved on the third threaded rod 12. The two second threaded rods 10 are symmetrically fixedly mounted on the surface of the U-shaped plate 13. A placement plate 14 is fixedly mounted on the upper surface of the mounting plate 1. One end of the third threaded rod 12 is rotatably connected to the surface of the placement plate 14, and the other end is fixedly mounted with an adjusting wheel 30.

[0037] By rotating the third threaded rod 12, the U-shaped plate 13 is controlled to move with the two second threaded rods 10. During the movement, the ends of the two second threaded rods 10 will move in the two thread grooves 9 respectively. Since the second threaded rods 10 cannot rotate, when the second threaded rods 10 move, under the action of the thread, the two rotating rods 7 will respectively rotate with the two support plates 8 relative to each other.

[0038] When the device needs to be used, the two support plates 8 can be controlled to rotate to a state perpendicular to the mounting plate 1, and then the bottom ends of the two support plates 8 can be controlled to abut against the ground, and the mounting plate 1 and the laser rangefinder 5 can be supported on the ground. At this time, the height of the laser rangefinder 5 from the ground is the highest. If the height needs to be adjusted, the two support plates 8 can be controlled to rotate to increase the distance between their bottom ends, so that the height of the laser rangefinder 5 from the ground will gradually decrease.

[0039] When the device is not needed, the two support plates 8 can be controlled to rotate to a horizontal state with the mounting plate 1, so that the two support plates 8 are folded and stored under the mounting plate 1, reducing the overall space occupied by the equipment, allowing staff to easily transport the laser rangefinder 5 and supporting equipment to disaster sites with complex terrain, such as landslide areas in deep mountain canyons and post-earthquake villages with rugged terrain, greatly improving the mobility of the equipment.

[0040] A grip opening 15 is formed on the surface of the placement plate 14 , and a sponge layer is bonded to the wall of the grip opening 15 .

[0041] After both support plates 8 are rotated and stored under the mounting plate 1 and are in a horizontal state with the mounting plate 1, the fingers can be passed through the grip 15, and then the device can be moved as a whole. The sponge layer can increase the comfort between the fingers and the contact surface of the grip 15.

[0042] A protection plate 16 is fixedly mounted on the surface of the support plate 8 , and the two protection plates 16 , the two support plates 8 and the mounting plate 1 form a protection mechanism 17 for covering the laser rangefinder 5 .

[0043] When the device is not needed, the two support plates 8 can be controlled to rotate to a state where they are horizontal to the mounting plate 1, which can reduce the space occupied by the device and facilitate carrying. At the same time, the laser rangefinder 5 will be covered in a protective mechanism 17 formed by two protective plates 16, two support plates 8 and the mounting plate 1 to prevent the laser rangefinder 5 from being exposed to the outside and easily damaged.

[0044] An extension component is provided on the surface of the protection plate 16, and the extension component is used to extend the supporting height of the support plate 8. The extension component includes a mounting rod 18 and an extension rod 19 fixedly mounted on the surface of the protection plate 16. A storage opening 20 is provided at one end of the mounting rod 18, and the extension rod 19 is slidably inserted in the storage opening 20. A locking component for locking the extension rod 19 is provided on the surface of the mounting rod 18, and the locking component includes a locking rod 21 and a telescopic spring 22. A sliding opening 23 is provided on the surface of the mounting rod 18, and the locking rod 21 is slidably inserted in the sliding opening 23, and a pull plate 24 is fixedly installed at one end. The two ends of the telescopic spring 22 are respectively fixedly connected to the surface of the pull plate 24 and the surface of the mounting rod 18, and a plurality of locking grooves 25 for inserting the end of the locking rod 21 are equidistantly provided on the surface corresponding to the position of the sliding opening 23.

[0045] When the two support plates 8 are both in a vertical state with the mounting plate 1, the height of the laser rangefinder 5 from the ground is still relatively low. By pulling the pull plate 24 and controlling the end of the locking rod 21 to move out of the locking groove 25, the locking of the extension rod 19 can be released. At this time, the telescopic spring 22 will be stretched, and then the extension rod 19 is controlled to move in the receiving opening 20 until the total length of the portion of the extension rod 19 extending out of the receiving opening 20 and the support plate 8 meets the height from the ground required to support the laser rangefinder 5. At this time, the extension rod 19 is controlled to move in the receiving opening 20 again, so that the locking groove 25 closest to the sliding opening 23 on the surface of the extension rod 19 corresponds to the position of the sliding opening 23, and then the pull plate 24 is released. The locking rod 21 will quickly move and reset under the elastic potential energy of the telescopic spring 22, and its end will be inserted into the locking groove 25 corresponding to its own position, thereby completing the locking of the extension rod 19 and improving the practicability of the device.

[0046] The surfaces of the support plate 8 , the protection plate 16 and the end of the extension rod 19 are all bonded with an anti-skid layer 26 , and the material of the anti-skid layer 26 is rubber.

[0047] The anti-skid layer 26 made of rubber has good elasticity and viscosity, so as to increase the friction between the contact surface between the support plate 8, the protection plate 16 and the extension rod 19 and the ground.

[0048] An electric telescopic rod 27 is fixedly mounted on the surface of the protection plate 16 , a servo motor 28 is fixedly mounted on the driving shaft of the electric telescopic rod 27 , an underground rod 29 is fixedly mounted on the output shaft of the servo motor 28 , and a through hole is opened on the surface of the protection plate 16 for the underground rod 29 to pass through.

[0049] After finding a suitable position for the required supporting device and completing the support of the mounting plate 1 and the laser rangefinder 5 by two supporting plates 8 or two extension rods 19, the electric telescopic rod 27 and the servo motor 28 are started to control the end of the buried rod 29 to pass through the through-hole and drill into the ground, thereby achieving the effect of auxiliary fixing the device, avoiding horizontal and lateral movement of the entire device during the measurement process, and improving the stability of the measurement process.

[0050] In the present invention, two support plates 8 for supporting the mounting plate 1 and the laser rangefinder 5 on the ground can be quickly controlled to rotate through the transmission components, which can reduce the occupied space of the entire equipment when the device is not needed, and is convenient to carry in a backpack or a rescue box, so that the staff can easily transport the laser rangefinder 5 and the supporting equipment to the disaster site with complex terrain. At the same time, the height of the supporting mounting plate 1 and the laser rangefinder 5 from the ground can also be adjusted, and the practicability is strong.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
