Description

Technical Field

[0001] The present application relates to the technical field of construction engineering detection equipment, and in particular to a construction engineering verticality detection device. Background Art

[0002] In construction projects, inclinometers are usually needed to measure the verticality of engineering structures such as boreholes, foundation pits, walls and dam slopes, and then calculate the bearing capacity of the site foundation, so as to control the quality of the construction project in advance.

[0003] Some existing inclinometers are mainly composed of a reader, a cable, a probe, a guide wheel and a brake block. Before measurement, one end of the cable is passed through the guide wheel and connected to the probe, and then the other end of the cable is connected to the reader. After that, the probe and the cable are placed in the inclinometer tube in the foundation and gradually go deeper. During measurement, the cable is moved up intermittently, and the distance of each upward movement is approximately the same. After a single upward movement is completed, the brake block is made to press the cable vertically down and the probe is stopped at the current position. After that, the result of the probe measurement is displayed in the reader and recorded by the staff. Then, the brake block is made to release the cable and the above work is repeated until the probe is separated from the inclinometer tube. The bearing capacity of the foundation is calculated based on the above measurement results.

[0004] However, in the process of the brake block cooperating with the guide wheel to lock the cable, due to the complex engineering environment, when an unexpected situation occurs, causing the end of the cable connected to the probe to be dragged (the end connected to the reading instrument is connected to a traction mechanism, and the traction mechanism is fixed, so that this end is not easily dragged accidentally), the cable is easily rubbed against the brake block, and the cable is pulled and damaged, thereby affecting the service life of the inclinometer.

[0008] Furthermore, an upper contact wheel is rotatably mounted at a lower position inside the rotating plate, and a lower side of the upper contact wheel forms a sliding contact with an upper side of the cable.

[0009] Furthermore, a mounting plate is fixedly installed on the side of the top plate facing the reader, a half frame is provided on the outer side of the rotating plate, the opening of the half frame faces the probe, a sealing rod is fixedly installed at the opening of the half frame, the sealing rod is located on the side of the rotating plate facing the probe, there is a gap between the sealing rod and the rotating plate, there is a gap between the part of the half frame corresponding to the side of the reader and the rotating plate, a telescopic part is fixedly installed inside the mounting plate, and the output rod of the telescopic part is fixedly connected with the half frame.

[0010] Furthermore, the upper contact wheel includes a rotating rod and a contact cylinder. The rotating rod is rotatably mounted at the lower position inside the rotating plate. The outer side of the rotating rod is sleeved with a contact cylinder, and the contact cylinder is made of rubber material.

[0011] Furthermore, there is a distance between the rotating rod and the contact cylinder, and the upper contact wheel further includes a supporting mechanism, and the rotating rod and the contact cylinder are connected via the supporting mechanism.

[0012] Furthermore, the support mechanism is a telescopic body and a telescopic outer rod, the telescopic body is fixedly installed on the outer side surface of the rotating rod at equal intervals in the circumferential direction, the telescopic outer rod is fixedly installed on the inner side surface of the contact cylinder and at a position corresponding to the telescopic body, and the telescopic outer rod is connected to the telescopic body.

[0013] Furthermore, the inner end of the telescopic outer rod is fixedly connected to the telescopic body.

[0019] Through the arrangement of the contact cylinder and the rotating rod, when the upper contact wheel further compresses the cable, the rotating rod will drive the contact cylinder to press the cable downward, causing the contact portion between the contact cylinder and the cable to deform. Through this action, the contact area between the contact cylinder and the cable is increased, thereby improving the fixing effect of the cable.

[0020] Through the arrangement of the contact cylinder and the groove, during the deformation of the contact cylinder, the groove on the surface of the contact cylinder corresponding to the cable is prone to produce an adsorption action with the surface of the cable. Through this action, the connection force between the contact cylinder and the cable is increased, so that the fixing effect of the contact cylinder on the cable is further improved, thereby further preventing the probe from causing the cable to fall.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Embodiment 1

[0032] See also Figure 1-Figure 3 , a verticality detection device for construction engineering, comprising a base 1, pins 2 are welded and fixed at the four corners of the bottom surface of the base 1 for inserting into the ground, pairs of plates 3 are fixedly installed on both sides of the upper surface of the base 1, a top plate 4 is fixedly installed at the upper position in the middle of the pairs of plates 3 on both sides, a lower contact wheel 5 is rotatably installed at the lower position in the middle of the pairs of plates 3 on both sides, a cable 6 is arranged between the top plate 4 and the lower contact wheel 5, the lower side of the cable 6 forms a sliding contact with the circumferential side of the lower contact wheel 5, a rotating plate 7 is arranged between the top plate 4 and the cable 6, the upper end of the rotating plate 7 is hingedly fixed to the lower surface of the top plate 4, the two ends of the cable 6 are respectively fixedly connected with a probe and a reader (existing technology, not shown in the figure), the lower end of the rotating plate 7 is inclined in the direction of the probe, the lower end of the rotating plate 7 is in sliding contact with the upper side of the cable 6, a No. 1 spring 8 is arranged on the side of the rotating plate 7 facing the probe, the upper end of the No. 1 spring 8 is fixedly connected to the lower surface of the top plate 4, and the lower end of the No. 1 spring 8 is fixedly connected to the side of the rotating plate 7 facing the probe.

[0033] Before measurement, the probe and cable 6 are placed in the inclinometer tube in the foundation and gradually penetrated until they are at the bottom. During measurement, the cable 6 drives the probe to move upward intermittently (using the existing traction mechanism or human traction), and the upward distance each time is approximately the same. In this process, the No. 1 spring 8 always applies pressure to the rotating plate 7, so that the rotating plate 7 cooperates with the lower contact wheel 5 to always maintain a sliding clamping action with the cable 6. When a single upward movement is completed, the traction force disappears, so that the probe and cable 6 are fixed at the current position through the clamping force between the rotating plate 7 and the lower contact wheel 5. After that, the measurement result of the probe is displayed in the reading instrument and is checked by the staff. Record, then, let the traction force pull the cable 6 again, and repeat the above work until the probe is separated from the inclinometer tube. Through the above measurement results, the bearing capacity of the foundation can be calculated. In the above process, when the end of the cable 6 connected to the probe is subjected to an unexpected drag force, the dragged cable 6 will drive the rotating plate 7 to compress the No. 1 spring 8 and deflect synchronously. Through the above action, hard friction between the cable 6 and the rotating plate 7 can be avoided, so that the cable 6 is not easy to wear. Afterwards, when the drag force disappears, the No. 1 spring 8 releases the elastic force and drives the rotating plate 7 to clamp the cable 6 again, so as to avoid the excessive drop of the cable 6 caused by the probe, thereby reducing the probability of damage to the probe.

[0034] See also Figure 1 and Figure 2 An upper contact wheel 9 is rotatably mounted at the lower position inside the rotating plate 7 , and the lower side of the upper contact wheel 9 forms a sliding contact with the upper side of the cable 6 .

[0035] When the rotating plate 7 cooperates with the lower contact wheel 5 to slide and clamp the cable 6 and the cable 6 is pulled, the friction force on the cable 6 is further reduced by the arrangement of the upper contact wheel 9 and the lower contact wheel 5, thereby further reducing the wear of the cable 6.

[0036] See also Figure 1-Figure 3 A mounting plate 10 is fixedly installed on the side of the top plate 4 facing the reader, a half frame 11 is arranged on the outer side of the rotating plate 7, the opening of the half frame 11 faces the probe, a sealing rod 12 is fixedly installed at the opening of the half frame 11, the sealing rod 12 is located on the side of the rotating plate 7 facing the probe, there is a gap between the sealing rod 12 and the rotating plate 7, there is a gap between the part of the half frame 11 corresponding to the side of the reader and the rotating plate 7, a telescopic member 13 (such as a combination of an electric-controlled telescopic cylinder and an output rod in the prior art) is fixedly installed inside the mounting plate 10, and the output rod of the telescopic member 13 is fixedly connected to the half frame 11 (the operating state of the telescopic member 13 is contraction-reset-extension-reset, reciprocating cycle).

[0037] After the cable 6 works normally and stops moving up once, the output rod of the telescopic member 13 is retracted, so that the half frame 11 drives the sealing rod 12 to contact the rotating plate 7, so that the rotating plate 7 and the upper contact wheel 9 are deflected, and the No. 1 spring 8 is stretched, so that the upper contact wheel 9 further applies a pressing force to the cable 6. After that, the output rod of the telescopic member 13 is reset, so that the half frame 11 and the sealing rod 12 are reset (at this time, the distance between the rotating plate 7 and the sealing rod 12 is increased, and the distance between the rotating plate 7 and the half frame 11 corresponding to the side of the reading instrument is reduced). Through this action, the fixing effect of the cable 6 is improved, and the probe is prevented from driving the cable 6 to fall, so that the probe detection result is not easily affected. After the measurement is completed, the output rod of the telescopic member 13 is extended, so that the part of the half frame 11 corresponding to the side of the reading instrument pushes the rotating plate 7, so that the rotating plate 7 returns to the initial sliding contact position of the cable 6, and then, the output rod of the telescopic member 13 is reset (at this time, the distance between the rotating plate 7 and the sealing rod 12, and the distance between the rotating plate 7 and the part of the half frame 11 corresponding to the side of the reading instrument are all returned to the initial state), and then the cable 6 is pulled up again, and the above actions are repeated (since the time of a single measurement is relatively fixed, the running time of the telescopic member 13 can be set according to the time of a single measurement. The timing device is a prior art and is not shown in the figure) until the probe is separated from the inclinometer tube.

[0038] Embodiment 2

[0039] See also Figure 1-Figure 6 This embodiment is a further improvement on the first embodiment, and the improvement lies in that the upper contact wheel 9 is mainly composed of a rotating rod 90, a contact cylinder 91, a telescopic body 92, a telescopic outer rod 93, a second spring 94 and a groove 95. The rotating rod 90 is rotatably installed at the lower position inside the rotating plate 7, and the contact cylinder 91 is sleeved on the outer side of the rotating rod 90, and the contact cylinder 91 is made of rubber material.

[0040] In the process of the upper contact wheel 9 further pressing the cable 6, the rotating plate 7 will drive the contact cylinder 91 to press down the cable 6 through the rotating rod 90, so that the contact part between the contact cylinder 91 and the cable 6 will undergo a certain deformation (because the contact cylinder 91 is made of rubber material). Through this action, the contact area between the contact cylinder 91 and the cable 6 is increased, thereby improving the fixing effect of the cable 6.

[0041] See also Figure 1-Figure 6 There is a distance between the rotating rod 90 and the contact cylinder 91, and a telescopic body 92 is fixedly installed on the outer side surface of the rotating rod 90 at equal intervals in the circumferential direction. A telescopic outer rod 93 is fixedly installed on the inner side surface of the contact cylinder 91 and at a position corresponding to the telescopic body 92. The inner end of the telescopic outer rod 93 forms a sliding card connection with the inner cavity of the telescopic body 92. A No. 2 spring 94 is arranged in the inner cavity of the telescopic body 92, and one end of the No. 2 spring 94 is fixedly connected with the inner end of the telescopic outer rod 93, and the other end of the No. 2 spring 94 is fixedly connected with the inner wall of the telescopic body 92.

[0042] In the process that the above-mentioned rotating plate 7 drives the contact cylinder 91 to press down the cable 6 through the rotating rod 90, the rotating rod 90 and the contact cylinder 91 will press the telescopic main body 92 and the telescopic outer rod 93 located below the rotating rod 90, so that the telescopic outer rod 93 of this part partially extends into the corresponding telescopic main body 92 and compresses the No. 2 spring 94, so that the contact cylinder 91 located below the rotating rod 90 will be further deformed, thereby further increasing the contact area between the contact cylinder 91 and the cable 6, and improving the fixing effect of the cable 6.

[0043] See also Figure 1-Figure 6 , grooves 95 are equidistantly provided on the outer side of the contact cylinder 91 in the circumferential direction (the grooves 95 equidistantly provided in the axial direction in the figure are for illustration only. In actual application, the length of the contact cylinder 91 and the number of the grooves 95 are in accordance with the diameter of the cable 6. Only one groove 95 may be provided in the axial direction, and the diameter of the single groove 95 is smaller than the diameter of the cable 6. At the same time, the length of the contact cylinder 91 is slightly larger than the diameter of the groove 95).

[0044] During the deformation of the contact cylinder 91, the groove 95 on the surface of the contact cylinder 91 corresponding to the cable 6 is easy to generate an adsorption action with the surface of the cable 6. Through this action, the connection force between the contact cylinder 91 and the cable 6 is increased, so that the fixing effect of the contact cylinder 91 on the cable 6 is further improved, thereby further preventing the probe from driving the cable 6 to fall. At the same time, through the adsorption force between the groove 95 and the cable 6 and the friction force of the groove 95 on the cable 6 (the groove 95 is provided on the surface of the contact cylinder 91, so that the surface of the contact cylinder 91 is concave and convex), the cable 6 can effectively drive the contact cylinder 91 to rotate when moving. Through this action, the sliding friction between the contact cylinder 91 and the cable 6 is transformed into rolling friction, thereby further reducing the wear of the cable 6.
