Description

Technical Field

[0001] The invention relates to building construction technology, and in particular to a building engineering measurement device. Background Art

[0002] In the field of construction engineering, surveying equipment is a key tool to ensure the quality and safety of the project. With the advancement of technology and the increasing complexity of construction projects, surveying equipment is also constantly developing and improving.

[0003] A Chinese invention patent with authorization announcement number CN117664084B discloses a special inclination measuring device for construction projects. The special inclination measuring device for construction projects is provided with a measuring mechanism. Through the use of a connecting plate, a fixing plate, a measuring tube, a measuring rod, a fixing frame, a measuring wheel, a pressure sensor, a moving rod and an angle measuring inclined plate, the marking pointer can be pointed to the zero scale line of the scale before measurement to achieve automatic zeroing of the scale. The operation is very simple, the measurement result is more accurate, and the use and work efficiency are improved. During the measurement process, the position of the marking pointer on the scale can directly reflect the actual inclination angle of the wall relative to the vertical surface, thereby accurately reading the degree of inclination of the wall, thereby achieving accurate measurement of the wall inclination, and the use is very convenient.

[0004] However, for the inclination of the building surface, not only the vertical inclination of the wall needs to be measured, but also the flatness of the wall needs to be measured. The above application cannot effectively detect the horizontal flatness of the wall, which results in that after the wall construction is completed, additional devices or methods are often required to detect the flatness of the wall, which increases the complexity and time cost of the measurement work. In addition, traditional measuring devices often cannot mark the problem area immediately when they find it, which makes it difficult to find and repair the problem area later.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1 to Figure 2 , a construction engineering measurement equipment, comprising a movable base 1 and a bracket 2 fixedly mounted on the upper surface of the movable base 1, and further comprising: a mounting frame 3, a mobile driving mechanism 4 and a measuring mechanism 5, wherein the measuring mechanism 5 is mounted on the mounting frame 3, and one side of the mounting frame 3 is connected to the mobile driving mechanism 4 for driving the mounting frame 3 to move in a direction perpendicular to the upper surface of the movable base 1;

[0032] The measuring mechanism 5 includes a measuring component 51, a marking component 52 and a triggering member 53. The measuring component 51 includes a measuring head, a moving frame 512, a pointer 513, a scale 514 and an elastic member. The moving frame 512 is slidably mounted on the upper surface of the mounting frame 3. The measuring head is arranged at one end of the moving frame 512 away from the bracket 2. The pointer 513 is arranged on a side of the moving frame 512 away from the measuring head. The scale 514 is arranged on one side of the pointer 513. The scale 514 is fixedly mounted on the mounting frame 3. One end of the moving frame 512 away from the measuring head is connected to the elastic member.

[0033] The measuring head includes two contact heads 511 arranged side by side. One side of the two contact heads 511 is respectively connected to a trigger member 53. The trigger member 53 is installed on a movable frame 512. When the two contact heads 511 move relative to each other along the length direction of the movable frame 512, the trigger member 53 can control the marking component 52 to mark the wall.

[0034] When measuring a wall, most existing measuring devices can only measure the longitudinal inclination of the wall, but cannot detect the transverse flatness of the wall. Other devices are required to measure the transverse flatness of the wall. In addition, during the measurement process, the area where the problem is found cannot be effectively marked, which causes limitations in the measurement process and reduces the efficiency of the measurement.

[0035] To this end, the present application provides two contact heads 511 in the measuring component 51, and pushes the movable base 1 to make the two contact heads 511 contact the wall. After the movable base 1 is fixed, the mounting frame 3 is driven to move up and down by the mobile driving mechanism 4. When the mounting frame 3 moves up and down, under the action of the elastic member, the moving frame 512 drives the two contact heads 511 to move up and down along the wall. Under the action of the contact head 511, the moving frame 512 moves, and the pointer 513 moves with the moving frame 512. The reading of the pointer 513 pointing to the scale 514 at the starting point and the end point of the up and down movement of the contact head 511, as well as the up and down movement distance of the contact head 511, can be read to obtain the inclination of the wall.

[0036] When the wall is uneven, the two contact heads 511 will move relative to each other along the length direction of the movable frame 512. At this time, the trigger member 53 can control the marking component 52 to mark the wall, thereby effectively marking the unevenness of the wall, making the measurement more efficient. In order to avoid measurement errors caused by the contact head 511 moving relative to the movable frame 512 due to the unevenness of the wall during measurement, at this time, the movement distance of one of the contact heads 511 relative to the movable frame 512 is recorded. Specifically, the distance that the contact head 511 moves relative to the movable frame 512 toward the wall can be defined as a positive value, and the distance that the contact head 511 moves relative to the movable frame 512 away from the wall can be defined as a negative value. The movement distance of the contact head 511 plus the movement distance of the movable frame 512 is the actual movement distance.

[0037] See also Figure 3 In one embodiment of the present invention, the mobile driving mechanism 4 includes a rotating driving member 41, a transmission belt 42, a slider 43 and two transmission wheels 44. The two transmission wheels 44 are rotatably installed on the same side of the bracket 2. The rotating driving member 41 is used to drive one of the transmission wheels 44 to rotate. The transmission belt 42 passes around the two transmission wheels 44. One side of the slider 43 is fixedly connected to the transmission belt 42, and the other side of the slider 43 is slidably connected to the bracket 2. One side of the mounting frame 3 is fixedly connected to the slider 43. The rotating driving member 41 is a motor or a rotating cylinder. One of the transmission wheels 44 is fixedly sleeved on the output shaft end of the rotating driving member 41, and the rotating driving member 41 is fixedly installed on the movable base 1;

[0038] The driving member 41 is rotated to drive the transmission wheel 44 connected thereto to rotate, the transmission wheel 44 drives the transmission belt 42 to move, and the transmission belt 42 drives the mounting frame 3 to move through the slider 43, thereby realizing the movement of the measuring mechanism 5 in a direction perpendicular to the upper surface of the movable base 1.

[0039] See also Figures 5 and 6 In one embodiment of the present invention, the marking assembly 52 includes a marking pen 521, a pen holder 522, an A spring 523, a fixed sleeve 524 and a driving assembly. The pen holder 522 is provided with a slot for inserting the marking pen 521. The marking pen 521 is partially inserted into the slot, and the marking pen 521 is fixed by the pen holder 522. The outer wall of the pen holder 522 is slidably connected to the inner wall of the fixed sleeve 524. One end of the A spring 523 is fixedly connected to the pen holder 522, and the other end of the A spring 523 is fixedly connected to the inner wall of the fixed sleeve 524. One side of the fixed sleeve 524 is connected to a driving assembly for driving the fixed sleeve 524 to move along the length direction of the moving frame 512.

[0040] When the two contact heads 511 move relatively along the length direction of the moving frame 512, the trigger member 53 controls the driving assembly to drive the fixed sleeve 524 to move toward the wall along the length direction of the moving frame 512. The fixed sleeve 524 drives the marking pen 521 to move toward the wall through the A spring 523 and the pen holder 522 and contact the wall. The marking pen 521 marks on the wall, thereby effectively marking the unevenness of the wall, which is convenient for subsequent search and repair work.

[0041] In one embodiment of the present invention, the driving assembly includes a telescopic driving member 525, a guide rod 526 and a mounting plate 527. The telescopic driving member 525 is a telescopic cylinder or a hydraulic cylinder. The moving end of the telescopic driving member 525 is fixedly connected to one end of the mounting plate 527. The fixed end of the telescopic driving member 525 is fixedly connected to the moving frame 512. The other end of the mounting plate 527 is fixedly connected to the guide rod 526. The outer wall of the guide rod 526 is slidably connected to the moving frame 512.

[0042] Under the guidance of the guide rod 526 , when the moving end of the telescopic driving member 525 moves, it will drive the mounting plate 527 to move, and the mounting plate 527 will drive the fixed sleeve 524 to move, thereby realizing the movement of the marking pen 521 .

[0043] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 In one embodiment of the present invention, the contact head 511 includes a sphere 5111 and a fixing seat 5112. The sphere 5111 is partially embedded in the fixing seat 5112. The sphere 5111 can rotate in any direction relative to the fixing seat 5112 with the center of the sphere 5111 as the center, thereby reducing the friction between the sphere 5111 and the wall surface, so as to extend the service life of the contact head 511.

[0044] In one embodiment of the present invention, the trigger member 53 includes a displacement sensor 530, an A rotating shaft 531, an A gear 532, two A racks 533, a truncated cone 534, an extrusion member 535, a pressure sensor 536 and a support frame 537. The displacement sensor 530 can be an optical sensor or an ultrasonic sensor. The displacement sensor 530 is fixedly mounted on the mobile frame 512 and is used to measure the moving distance of one of the contact heads 511 or one of the A racks 533 relative to the mobile frame 512. The two fixed seats 5112 are fixedly connected to the ends of the two A racks 533 on one side away from the sphere 5111. The two A racks 533 are respectively arranged on the two sides of the A gear 532. side, and one side of the two A racks 533 is respectively meshed with the A gear 532, the A gear 532 is fixedly sleeved on the upper end of the A rotating shaft 531, the A rotating shaft 531 is rotatably installed on the moving frame 512, the bottom end of the A rotating shaft 531 is fixedly connected to the round table 534, the bottom surface of the round table 534 is an inclined surface, the bottom surface of the round table 534 is in contact with the top of the extrusion piece 535, the outside of the extrusion piece 535 is slidably connected with the support frame 537, the outside of the extrusion piece 535 is sleeved with a C spring, the top of the C spring is fixedly connected to the extrusion piece 535, the bottom of the C spring is fixedly connected to the support frame 537, the top of the support frame 537 is fixedly connected to the moving frame 512, and the pressure sensor 536 is arranged at the bottom of the extrusion piece 535;

[0045] When the two contact heads 511 move relative to each other, the two contact heads 511 drive the A gear 532 to rotate through the two A racks 533, and the A gear 532 drives the A rotating shaft 531 to rotate, thereby driving the truncated table 534 to rotate, and the bottom surface of the truncated table 534 pushes the extruding piece 535, and the extruding piece 535 moves down and contacts the pressure sensor 536. The pressure sensor 536 sends a control signal to the telescopic driving piece 525 through an external controller, and the moving end of the telescopic driving piece 525 extends, so that the marking pen 521 is marked on the wall. When the contact heads 511 move to the flat wall surface, the two contact heads 511 move relative to each other and reset. Similarly, the truncated table 534 rotates in the opposite direction. Under the action of the C spring, the extruding piece 535 is separated from the pressure sensor 536. The pressure sensor 536 sends a control signal to the telescopic driving piece 525 through an external controller, and the moving end of the telescopic driving piece 525 is shortened, and the marking pen 521 is separated from the contact with the wall surface, and the marking is completed.

[0046] In one embodiment of the present invention, the trigger member 53 also includes an adjustment component 538, which includes a support seat 5381, a damping spring 5382, a fixed plate 5383, a screw 5384 and a vertical rod 5385.

[0047] Since the unevenness of the wall surface is different, the distance between the pressure sensor 536 and the bottom end of the extrusion piece 535 can be set to achieve the effect of marking the wall surface with the marking pen 521 when the wall surface is measured to exceed the specified range. By rotating the screw 5384, under the guidance of the vertical rod 5385, the support seat 5381 drives the pressure sensor 536 to move up and down through the damping spring 5382 and the fixing plate 5383, thereby effectively adjusting the distance between the pressure sensor 536 and the extrusion piece 535, that is, the trigger condition of the marking component 52 can be adjusted according to the actual situation.

[0048] See also Figure 2 and Figure 5 In one embodiment of the present invention, a locking member 539 is further provided. The locking member 539 is used to prevent the A rotating shaft 531 from rotating around the axis of the A rotating shaft 531. The locking member 539 includes a fixing ring 5391, a latch 5392, a positioning frame 5393 and a plug hole 5394 provided on the fixing ring 5391. The fixing ring 5391 is fixedly sleeved on the top of the A rotating shaft 531. The outer portion of the latch 5392 is slidably connected to the positioning frame 5393. The latch 5392 can be partially inserted into the plug hole 5394. The bottom end of the positioning frame 5393 is fixedly connected to the moving frame 512.

[0049] When the wall surface is relatively flat and there is no need to detect the flatness of the wall surface, the pin 5392 can be inserted into the socket 5394 on the fixing ring 5391. At this time, under the action of the pin 5392, the fixing ring 5391 and the A rotating shaft 531 cannot rotate, so that the two contact heads 511 cannot move relative to each other. At this time, the inclination of the wall surface can be measured by keeping one of the contact heads 511 in contact with the wall surface.

[0050] See also Figure 2 and Figure 4In one embodiment of the present invention, it further includes an amplifying assembly 54, which includes a B gear 541, a B shaft 542, a B rack 543 and a C rack 544. The bottom end of the B shaft 542 is rotatably connected to the moving frame 512, the B gear 541 is fixedly sleeved on the outside of the B shaft 542, and the two sides of the B gear 541 are respectively meshed with the B rack 543 and the C rack 544, one side of the B rack 543 is fixedly connected to the mounting frame 3, one side of the C rack 544 is slidably connected to the mounting frame 3, and the other side of the C rack 544 is fixedly connected to the pointer 513;

[0051] Since the inclination of the wall is generally small, during the measurement process, the movement amplitude of the pointer 513 is small, which may easily cause errors in the reading and recording process by the staff. For this reason, an amplifying component 54 is provided. When the mobile frame 512 moves, the B shaft 542 drives the B gear 541 to move. Since the B rack 543 is fixed on the mounting frame 3, it will rotate synchronously when the B gear 541 moves. The B gear 541 drives the C rack 544 to move. The movement amplitude of the C rack 544 is a multiple of the movement amplitude of the mobile frame 512, so that the movement amplitude of the pointer 513 is increased, which can facilitate the staff to record and calculate and reduce the occurrence of errors. After the reading and recording are completed, the actual moving distance of the mobile frame 512 is obtained by conversion.

[0052] See also Figure 2 and Figure 4 In one embodiment of the present invention, one end of the mobile frame 512 away from the measuring head is fixedly connected to a cross bar 55, the outside of the cross bar 55 is slidably connected to the mounting frame 3, the elastic member is a B spring 56, the B spring 56 is sleeved on the outside of the cross bar 55, one end of the B spring 56 is fixedly connected to the mobile frame 512, and the other end of the B spring 56 is fixedly connected to the mounting frame 3. Under the action of the B spring 56, the mobile frame 512 can be reset after moving.

The control unit can select any controller to be connected to the electrical parts in the present application, so as to control the opening and closing operation of each electrical part. This part is the prior art. Here, a single-chip microcomputer can be provided as a control unit for display.
