[0002] Construction engineering refers to the planning, investigation, design, construction, completion and other technical work and completed engineering entities for the construction, reconstruction or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines and equipment. It also refers to the construction of various houses and buildings, also known as construction workload. A large amount of surveying and measuring is required in construction engineering operations, and wheeled distance meter is one of the measuring tools. Wheeled distance meter is a kind of distance meter, which is mainly designed and manufactured for distance measurement and is suitable for various ground conditions, including grassland, hillside, rugged construction site, etc. For this reason, the use of wheeled distance meter is increasing;

[0003] The wheeled distance meter is basically composed of a bracket, a running wheel, an encoder and a display. The existing wheeled distance meters on the market are currently limited in function and can only measure distances. During construction operations, when measuring the ground, it is also necessary to measure data such as ground inclination, building angle, height, etc. Therefore, it is generally necessary to carry multiple instruments together for operation, which is very troublesome. At the same time, when the current wheeled distance meters are in use, due to the different body shapes and habits of the workers, the measuring wheels are often separated from the ground during operation due to the influence of body shape and habits, resulting in measurement errors. Therefore, we propose a construction engineering measurement device. Summary of the invention

[0016] The present invention provides a construction engineering measurement device, which has the following beneficial effects:

[0017] 1. When the construction engineering measurement equipment measures the distance and inclination of the ground, the rectangular extension rod can be controlled to move down to the limit position. At this time, the bottom of the supporting walking wheel and the bottom of the distance measuring walking wheel are in a horizontal position. The liquid level can be used to determine whether the measuring support rod is in a vertical state. During measurement, both the supporting walking wheel and the distance measuring walking wheel are moving. When the measuring support rod is in a vertical state, if the ground is uneven, the bottom of the supporting walking wheel is used as the base point. At this time, the distance measuring walking wheel contacts the ground, and the ground appears at an angle, which will definitely raise or lower the height of the distance measuring walking wheel. At this time, the mounting frame will rotate, and the rotation of the mounting frame will drive the mounting shaft to rotate. The transmission rod is rotated by the same angle through the cooperation of the slave bevel gear and the main bevel gear, thereby causing the pointer to rotate. The value pointed to by the pointer rotation angle is the inclination angle, and the distance and angle measurement is realized at the same time. In addition, since the mounting frame is installed using the mounting shaft during the measurement process, the distance measuring walking wheel contacts the ground by gravity during the measurement process. The staff will not affect the measurement of the distance measuring walking wheel when lifting or lowering the height of the measuring support rod during the operation, and it also avoids the distance measuring walking wheel being affected by the measuring support rod and leaving the ground, making it more stable to use.

[0018] 2. The construction engineering measurement equipment has two sets of flip plates installed on one side of the distance measuring walking wheel, and the two flip plates can be rotated with the installation rod as the point. The purpose of the flip plate is to measure the angles at the corners of the building. When in use, the screws fixing the flip plate are removed, and then the flip plate is flipped. The two flipped flip plates are partially located on the outside of the distance measuring walking wheel. At this time, one edge of the two flip plates forms a straight line, and it can be observed whether the building corner is 90 degrees. When the angle needs to be measured, the measuring support rod is kept vertical and the flip plate is placed against the building surface. At this time, since the measuring support rod is vertical and the building surface is inclined, the mounting frame needs to rotate an angle to make the flip plate contact the wall. At this time, the inclination angle of the building surface can be judged by the value pointed to by the pointer, which can play the role of angle measurement and achieve multi-purpose.

[0019] 3. The construction engineering measurement equipment stores the pigments in a paint box. When it is necessary to record the measurement route and mark the measurement points, a paint box can be installed, and the pump in the inner cavity of the paint box can be used to spray the pigments through the nozzle for marking.

[0020] 4. The construction engineering measurement equipment, through the use of the handle, under normal use, puts the two handles together, at this time holds the combined handle and pushes the entire measurement tool to move, when the measuring ground condition is good, the ground is relatively flat, or long-distance measurement is performed, the measurement personnel can remove the restraint belt, and then separate the handles and rotate them to both sides until the outer side of the handles is against the inner wall of the push rod. At this time, the two handles are in a herringbone shape, and the staff can stand on the inner side of the herringbone-shaped handle so that the arc-shaped groove on the inner side of the handle contacts the two sides of the human waist, and pass the restraint belt through the fixing ring at the end of the handle, and then tie it around the body, if necessary, pass through a few more rolls to fix the handle to the human body, at this time, the staff can walk directly without using their hands to hold the measuring tool, and push the equipment to perform walking measurement by connecting the waist to the handle, which can free the staff's hands to a certain extent and is more convenient to use.

DETAILED DESCRIPTION

[0035] 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.

[0036] See also Figures 1 to 13The present invention provides a technical solution: a construction engineering measurement equipment, comprising a measurement support rod 1, a pushing structure is installed on the measurement support rod 1, an avoidance groove 2 is opened on one side of the measurement support rod 1, a mounting shaft 36 is rotatably installed in the inner cavity of the avoidance groove 2, a main bevel gear 38 is fixedly connected to the middle of the mounting shaft 36, a mounting frame 11 is fixedly sleeved on the surface of the main bevel gear 38 and located on both sides of the slave bevel gear 37, a measuring structure is installed at one end of the mounting frame 11, and the measuring structure consists of a distance measuring walking wheel 14, a flip plate 13, a rotating shaft 15 and an encoder 17, a rotating shaft 15 is rotatably installed at one end of the mounting frame 11, an encoder 17 is installed on one side of one end of the mounting frame 11, a distance measuring walking wheel 14 is fixedly connected to the surface of the rotating shaft 15, a mounting rod 19 is installed on one side of the distance measuring walking wheel 14, and a flip plate 13 is rotatably connected to the mounting rod 19;

[0037] The top of the measuring support rod 1 is fixedly connected to a placing table 20, and an inclination dial 23 and a liquid level 21 are embedded inside the placing table 20. The inside of the measuring support rod 1 is rotatably connected to a transmission rod 3, and the top end of the transmission rod 3 extends to the inner cavity of the inclination dial 23 and is connected to a pointer. The bottom end of the transmission rod 3 is fixedly connected to a slave bevel gear 37, and the slave bevel gear 37 is meshed with the main bevel gear 38;

[0038] A telescopic support mechanism is installed inside the measuring support rod 1.

[0039] The pushing structure includes a rotating sleeve 5, a push rod 6, and a handle 7. The rotating sleeve 5 is rotatably installed to the top side of the measuring support rod 1. The push rod 6 is fixedly connected to one side of the rotating sleeve 5. Two mounting pins 26 are rotatably connected to the inside of one end of the push rod 6. The surfaces of the two mounting pins 26 are fixedly connected to the handle 7.

[0040] By rotating the sleeve 5 to be rotatably sleeved on the measuring support rod 1, the direction of the push rod 6 can be adjusted, and then the direction of the push rod 6 can be adjusted according to different usage conditions, so as to facilitate the operation of the staff.

[0041] A surrounding plate 22 is connected to the outer side of the top of the placement table 20 . A display is installed on the upper surface of the placement table 20 , and the display is electrically connected to the encoder 17 .

[0042] The telescopic support mechanism includes a rectangular slide 12, a rectangular extension rod 9, a screw 10 and a supporting walking wheel 8. A rectangular slide 12 is provided at the bottom of the measuring support rod 1. A rectangular extension rod 9 is slidably installed in the inner cavity of the rectangular slide 12. A supporting walking wheel 8 is installed at the bottom of the rectangular extension rod 9. The inner rotation of the measuring support rod 1 is connected to the screw 10, which is threadedly sleeved into the inner cavity of the rectangular extension rod 9. A worm gear 24 is fixedly connected to the top of the screw 10. The inner rotation of the measuring support rod 1 is connected to the worm 25, and the worm 25 is meshed with the worm gear 24. An operating rod 29 is slidably installed in the inner cavity of the worm 25. The other end of the operating rod 29 extends to the outside of the measuring support rod 1. A reset spring 27 is fixedly connected to the inner cavity of the worm 25, and one end of the reset spring 27 is connected to one end of the operating rod 29.

[0043] The operating rod 29 is sleeved by the worm 25, and the outer wall of one end of the operating rod 29 is fitted with the inner wall of the worm 25. The one end of the operating rod 29 is pulled by the return spring 27. When in use, the operating rod 29 is pulled to move outward, and then the operating rod 29 is rotated to rotate the worm 25. The worm 25 drives the worm wheel 24 to rotate and then drives the screw 10 to rotate. The rectangular extension rod 9 is driven to move by the rotation of the screw 10, and the screw 10 can be adjusted to move up and down.

[0044] During conventional distance measurement, the rectangular extension rod 9 is in a retracted state, and the grip 7 is held to push the mounting frame 11 to move, thereby causing the distance measuring walking wheel 14 to roll along the ground, and the distance value is displayed on the display through the encoder 17 for detection. Since the mounting frame 11 is installed through the mounting shaft 36, the distance measuring walking wheel 14 contacts the ground by gravity during the measurement process. The worker does not affect the measurement of the distance measuring walking wheel 14 when lifting or lowering the height of the measuring support rod 1 during the operation, and also avoids the distance measuring walking wheel 14 being affected by the measuring support rod 1 and leaving the ground.

[0045] When it is necessary to measure the distance and inclination of the ground, the rectangular extension rod 9 can be controlled to move down to the extreme position. At this time, the bottom of the supporting walking wheel 8 and the bottom of the distance measuring walking wheel 14 are in a horizontal position. The liquid level 21 can be used to determine whether the measuring support rod 1 is in a vertical state. During measurement, both the supporting walking wheel 8 and the distance measuring walking wheel 14 are moving. When the measuring support rod 1 is in a vertical state, if the ground is uneven, with the bottom of the supporting walking wheel 8 as the base point, the distance measuring walking wheel 14 is in contact with the ground, and the ground has an angle, which will definitely raise or lower the height of the distance measuring walking wheel 14. At this time, the mounting frame 11 will rotate, and the rotation of the mounting frame 11 will drive the mounting shaft 36 to rotate. The transmission rod 3 is rotated by the same angle through the cooperation of the slave bevel gear 37 and the main bevel gear 38, so that the pointer is rotated. The value pointed to by the pointer rotation angle is the inclination angle.

[0046] There are two ways to use it. The first is to measure the inclination of a specified position. At this time, there is no need to control the measuring support rod 1 to be in a vertical state during the movement of the measuring support rod 1. After reaching the specified position, adjust the measuring support rod 1 to be vertical. The other is to measure the flatness of the entire ground. At this time, it is necessary to keep the measuring support rod 1 in a roughly vertical state. By observing the changes in the pointer, the parallelism and inclination of the entire ground can be roughly judged. It is suitable for large-area measurement.

[0047] A horizontal column 34 is fixedly connected to one side of the inner cavity of the avoidance groove 2 and located below the mounting frame 11 . One end of the horizontal column 34 extends to the outside of the avoidance groove 2 and is rotatably connected to a limit plate 35 . A rubber pad is connected between the limit plate 35 and the horizontal column 34 .

[0048] After the mounting frame 11 is rotated downward by 90 degrees, the distance measuring walking wheel 14 is located below the measuring support rod 1, and the cross column 34 and the limit plate 35 pass through the inner cavity of the mounting frame 11. At this time, the limit plate 35 is rotated, and the inner side of the limit plate 35 contacts the surface of the mounting frame 11, so that the limit plate 35 is turned from the numerical state to the horizontal state, thereby limiting the position of the mounting frame 11, and the measuring support rod 1 can be pushed for measurement. This is one of the forms of use of this product. In this form, the traditional distance measuring wheel is used in the same way. At the same time, the product's footprint can be reduced when stored, which is more convenient to carry. See Fig.12 .

[0049] A threaded mounting hole is provided on one side of the distance measuring walking wheel 14 , and an arc-shaped recess 18 is provided on the side of the flip plate 13 . Screws are installed on the flip plate 13 , and the screws are threadedly connected to the inner cavity of the threaded mounting hole.

[0050] By installing two sets of flip plates 13 on one side of the distance measuring walking wheel 14, and the two flip plates 13 can rotate with the mounting rod 19 as a point, the purpose of the flip plate 13 is to measure the angle of the corner of the building. When in use, the screws fixing the flip plate 13 are removed, and then the flip plate 13 is flipped. The flipped flip plates 13 are partially located on the outside of the distance measuring walking wheel 14. At this time, one side of the two flip plates 13 forms a straight line, which can be referred to Fig.11 , it can be observed whether the building corner is 90 degrees. When the angle needs to be measured, the measuring support rod 1 is kept vertical and the flip plate 13 is placed against the building surface. At this time, since the measuring support rod 1 is vertical and the building surface is inclined, the mounting frame 11 needs to be rotated to make the flip plate 13 contact the wall surface. At this time, the inclination angle of the building surface can be judged by the value pointed by the pointer. It should be noted that after the flip plate 13 is flipped, its bottom needs to be parallel to the ground. At the same time, the rotation of the ranging walking wheel 14 needs to be limited during this measurement process. The existing electronic brake structure can be used to limit the ranging walking wheel 14, which can play a role in angle measurement and achieve multi-purpose.

[0051] A hexagonal mounting hole 16 is provided on the other side of one end of the mounting frame 11, and a screw hole is provided inside the mounting frame 11 and at the bottom of the inner cavity of the hexagonal mounting hole 16. A paint box 30 is installed on the other side of one end of the mounting frame 11, and a hexagonal column 32 is installed inside the paint box 30, and one end of the hexagonal column 32 passes through the paint box 30 and is sleeved into the inner cavity of the hexagonal mounting hole 16. A bolt is movably sleeved in the inner cavity of the hexagonal column 32, and one end of the bolt is threadedly connected to the inner cavity of the screw hole. A pump 33 is installed in the inner cavity of the paint box 30, and a nozzle 31 is installed at the bottom of the paint box 30, and the pump 33 is connected to one end of the nozzle 31.

[0052] By combining the hexagonal column 32 and the hexagonal mounting hole 16, a paint box 30 can be installed on one side of the mounting frame 11. The paint box 30 is used to store the paint. When it is necessary to record the measurement route and mark the measurement point, the paint box 30 can be installed. The pump 33 in the inner cavity of the paint box 30 can be used to spray the paint through the nozzle 31 for marking. The pump 33 needs to be powered by an external battery, and the staff can carry the battery for power supply.

[0053] One end of the two handles 7 is connected to a fixing ring, and a restraining belt is passed through the fixing ring. One end of the push rod 6 is fixedly connected to an elliptical fixing block 4, and the outer side of the elliptical fixing block 4 is connected to an iron sheet. The inner side of the handle 7 is fixedly connected to a magnet adsorbed by the iron sheet. The inner side of the handle 7 is provided with an arc groove. One side of the rotating sleeve 5 is threadedly connected to a butterfly bolt, and one end of the butterfly bolt passes through the rotating sleeve 5 and contacts with the measuring support rod 1.

[0054] By using the grip 7, in normal use, the two grips 7 are put together, and the positions of the two grips 7 are limited due to the adsorption of the magnet and the iron sheet. At the same time, a binding belt can be used to wrap around the two grips 7. At this time, the combined grip 7 can be held by hand to push the entire measuring tool to move.

[0055] When the ground condition is good and flat, or when measuring long distances, the surveyor can remove the restraint belt, then separate the handles 7 and rotate them to both sides until the outer side of the handles 7 is against the inner wall of the push rod 6. At this time, the two handles 7 are in a herringbone shape, and the staff can stand on the inner side of the herringbone-shaped handles 7 to make the arc-shaped grooves on the inner side of the handles 7 contact the two sides of the human waist, and pass the restraint belt through the fixing ring at the end of the handles 7 and then tie it around the body. If necessary, more wraps can be passed through to fix the handles 7 to the human body. At this time, the staff can walk directly without holding the measuring tool with their hands, and the walking measurement can be performed by connecting the waist to the handles 7 to push the equipment, which can free the staff's hands to a certain extent and is more convenient to use.

[0056] A receiving groove 28 for receiving an operating rod 29 is provided on the other side of the measuring support rod 1 , and a distance scale is provided on the front side of the measuring support rod 1 and the rectangular extension rod 9 .

[0057] Two sets of distance scales are provided on the measuring support rod 1, the initial value of one set of scales is the distance between the bottom of the supporting walking wheel 8 and the bottom of the measuring support rod 1 after the rectangular extension rod 9 is retracted to the extreme position, and the initial value of the other set of scales is the distance between the bottom of the supporting walking wheel 8 and the bottom of the measuring support rod 1 after the rectangular extension rod 9 is extended to the extreme position. The two sets of scales can be temporarily used to measure the height and length of objects.

[0058] 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.
