Description

[0001] This case is a divisional application. The original application was entitled "A Portable Engineering Surveying Device", with an application date of 2022-10-27 and an application number of 202211322565.2. Technical Field

[0002] This invention relates to the field of surveying equipment technology, and more specifically to a surveying device suitable for field engineering surveys. Background Technology

[0003] Surveying equipment generally includes a surveying instrument and a tripod. Surveyors need to carry the surveying instrument and tripod separately. The surveying instrument comes with a dedicated carrying case, and the tripod is carried on the shoulder via straps. Several problems arise when conducting geological surveys in complex terrain: carrying the tripod directly on the shoulder affects the normal walking of personnel and is inconvenient to carry; the tripod is prone to collisions with personnel and surrounding hard objects, causing injury to personnel or damage to the tripod; the surveying instrument needs to be opened from the carrying case and placed on the tripod each time it is used, and then put back into the carrying case after use, which is a cumbersome operation process; the surveying instrument is not protected as a whole during the process of taking it out and putting it back, and due to the complex terrain, there is a risk of accidental drops and collisions.

[0004] Therefore, how to solve the above-mentioned technical problems has become the challenge faced by this invention. Summary of the Invention

The back box of the surveying instrument is movably connected to the surveying instrument, and the opening and closing components are fixedly connected to the connecting components.

[0008] The top of the support back box is provided with a connecting plate that connects and mates with the bottom of the surveying instrument, and the bottom of the support back box is provided with a through hole that slidably mates with the support.

[0009] The back box of the surveying instrument is rectangular in structure. The left and right sides of the back box of the surveying instrument are symmetrically connected to protective sleeve boxes that cooperate with the protective sleeve. There are two protective sleeves, which are slidably engaged with the left and right sides of the surveying instrument respectively.

[0010] The protective sleeve has several horizontally arranged sliding grooves on its front and rear outer walls, and the sliding grooves are slidably connected to the guide strips that are horizontally connected to both sides of the inside of the back box of the surveyor.

[0011] A vertically upward-facing connecting column with internal threads is fixedly connected to the center of the top of the surveying instrument. The connecting component includes a first screw rod whose bottom is threadedly connected to the connecting column. The first screw rod is threadedly connected to the through hole at the top of the surveying instrument's back box, and its top end extends through the top of the surveying instrument's back box and is fixedly connected to the rotating disk.

[0012] The bottom of the back box of the surveying instrument is provided with an opening, and the opening is movably fitted with a cover.

[0013] The opening and closing assembly includes a rope reel coaxially sleeved on the outer side of the portion of the first screw located above the back box of the surveying instrument. The rope reel is wound with two traction ropes. The two traction ropes pass through the outer side of the protective sleeve and into the inner side of the back box of the surveying instrument via rope wheels provided on both sides of the protective sleeve and are fixedly connected to the center of the outer side of the protective sleeve on the same side.

[0014] A plurality of first springs are fixedly connected between the inner wall of each of the protective sleeves and the outer wall of the protective sleeve located on the same side;

[0015] The top of the back box of the surveying instrument is provided with a fixing plate, and the fixing plate is slidably connected with a pin. The end of the pin is inserted into a fixing hole on the rotating disk.

[0016] The opening has symmetrical slots on both sides, and L-shaped inserts are symmetrically slidably connected to both sides of the cover. The outer ends of the inserts are inserted into their corresponding slots. A second spring is fixedly connected between the two inserts on opposite sides. The top of the cover is in contact with the bottom of the surveying instrument.

[0017] The bottom of the surveying instrument's back box has symmetrical support blocks on both sides.

[0018] The support back box has a rectangular structure. A connecting plate that cooperates with the surveying instrument is provided at the top center of the support back box. A groove is provided at the top center of the connecting plate. A second screw that passes through the upper and lower sides is threadedly connected to the center of the connecting plate. A rotating handle is coaxially fixedly connected to the bottom end of the second screw. The top end of the second screw is threadedly connected to the bottom of the surveying instrument.

[0019] A sliding sleeve is vertically arranged below the rotating handle, communicating with the through hole at the bottom of the bracket back box, and the bracket is slidably connected to the inside of the sliding sleeve;

[0020] The bracket back box has an installation opening on its upper side, and a sealing plate is hinged to the installation opening.

[0021] The bracket includes a mounting plate whose diameter matches the inner diameter of the sliding sleeve. The mounting plate is slidably connected to the inner side of the sliding sleeve and its central axis coincides with the central axis of the sliding sleeve.

[0022] The bottom of the mounting plate is rotatably connected to three fixed rods along the circumferential direction. Each fixed rod is slidably connected to a support leg, and a fixing component is provided between the fixed rod and its corresponding support leg.

[0023] The mounting plate is symmetrically fixedly connected to horizontally arranged lifting rods on both sides. The lifting rods pass through the sliding sleeve to the outside of the bracket back box. Corresponding to the lifting rods, the sliding sleeve and the bracket back box are respectively vertically opened from top to bottom with a first guide groove and a second guide groove that slide with the lifting rods.

[0024] The second guide groove has symmetrical ear plates on both sides at the upper and lower ends, which are fixedly connected to the outer wall of the bracket back box. The ear plates have connecting holes, and corresponding to the positions of the connecting holes, insertion holes are provided on both sides of the lifting rod. The connecting holes and the insertion holes are fitted with fixing bolts and fixing nuts.

[0025] A connecting plate is fixedly connected between the outer wall of the sliding sleeve and the inner side of the support back box.

[0026] The top of the connecting plate is fitted with a cover plate;

[0027] Both the side of the support case away from the sealing plate and one side of the surveyor case are equipped with shoulder straps.

[0028] In practical use, the surveyor carries the surveying device to the surveying location via shoulder straps using the surveyor's back case and the support back case. First, the support is installed by unscrewing the fixing bolts on both sides from the lifting rods. The lifting rods are then pulled out from the bottom of the support back case, unfolding the fixing rods and legs. The fixing rods are then secured to the lower ear plate of the support back case using fixing bolts and nuts. The length of the legs is adjusted and secured with fasteners. The top cover of the support back case is then removed, completing the preparation for connecting to the surveyor. Next, the insert plate on the bottom cover of the surveyor's back case is pressed to detach from the connector, and the cover is removed. The entire surveyor's back case is placed on the support back case from above, with the surveyor's bottom resting on the connecting plate. The cover is then opened to expose the installation port. The surveyor then tightens the second screw using the rotating handle. After connecting the bottom of the surveying instrument, rotate the rotating disc to gradually disengage the first screw from the top of the surveying instrument. At the same time, the rope reel retracts the two migration ropes, pulling the protective sleeves into the protective sleeve boxes on both sides. The surveying instrument back box is then disconnected from the surveying instrument. The position of the connecting parts is then fixed by the pin. The surveying instrument back box is then removed from the top, and the surveying instrument can be protected on the sides. After completion, the surveying instrument is placed back into the surveying instrument back box from the top. The pin is pulled out, and under the action of the first spring, the two protective sleeves on both sides close together, sealing the surveying instrument inside. At the same time, the first screw rotates and connects with the threaded connection post on the top of the surveying instrument. Finally, the second screw is loosened to disconnect the connecting disc from the surveying instrument. The cover of the surveying instrument back box is then reinstalled, and the bracket is retracted into the bracket back box. The surveying device can then be carried to the next surveying point using a double-shoulder carrying method.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. This invention allows the surveying device to be carried in two backpacks, making it more convenient for surveyors to carry.

[0031] 2. This invention protects the surveying instrument inside the back case with a protective sleeve, and the bracket is also protected inside the back case, thus avoiding accidental collision damage to the surveying device during transport.

[0032] 3. When using this invention, the height of the stand back case is matched with the stand, which effectively reduces the overall length of the stand and makes it easier to carry;

[0033] 4. This invention can keep the surveying instrument under the protection of the protective cover and the back box of the surveying instrument during docking with the bracket and during storage and movement, thus avoiding accidental collision damage caused by the movement of the surveying instrument;

[0034] 5. The present invention has a reasonable structural design. The connection and disconnection between the back box of the surveyor and the surveyor can be realized through the opening and closing components, which can also link the protective cover and the surveyor to merge and separate, making the operation simpler and faster.
