Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a floor thickness measuring device. Background Art

[0002] After the construction of the floor slab is completed, it is necessary to detect the thickness of the floor slab, and the detection of the floor slab thickness is realized by a floor slab thickness detector. During the use of the floor slab thickness detector, the receiver and the transmitter need to be respectively located on the upper and lower surfaces of the floor slab for detection. During the detection process, two people are required to operate, that is, one person operates the receiver upstairs and the other person operates the transmitter downstairs. This requires a lot of manpower, and the work intensity of the staff downstairs is relatively large. Since the staff upstairs cannot see the transmitter, they need to move the receiver within a large range to align with the transmitter, which makes the alignment difficult and takes a lot of time. Content of the Utility Model

[0003] The utility model provides a floor thickness measuring device that reduces the measurement difficulty and improves the measurement efficiency to solve the deficiencies of the prior art.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows: a floor thickness measuring device includes a box body, a telescopic mechanism, a transmitting head and a receiver matching the transmitting head. The receiver is an independent structure. When the box body is placed flat, its top is open, and a detachable box cover is installed on the top opening of the box body. The box body houses the telescopic mechanism and the transmitting head. The fixed end of the telescopic mechanism is hinged to the bottom plate of the box body, and the transmitting head is installed on the telescopic end. A locking mechanism is also installed on the bottom plate, on one side close to the fixed end of the telescopic mechanism. The locking mechanism is used to lock the telescopic mechanism and the bottom plate in a relatively perpendicular state.

[0005] A camera is installed on the transmitting head. A traveling mechanism driven by a motor is installed at the bottom of the box body. A display screen, a first controller, a rocker and control buttons are also installed on the receiver. A second controller is installed on the box body. The display screen, the rocker and the control buttons are connected to the first controller. The camera, the electric telescopic rod and the traveling mechanism are connected to the second controller. The first controller and the second controller communicate data wirelessly. The display screen is used to display the real-time shooting picture of the camera. The control buttons are used to control the opening and closing of the telescopic mechanism and the traveling mechanism. The rocker is used to control the moving direction of the traveling mechanism.

[0006] In this embodiment, the locking mechanism includes a fixed rod and a sliding sleeve. The fixed rod is hinged to the bottom plate and near the fixed end of the telescopic mechanism. The fixed rod is opposite to the telescopic mechanism in terms of the rotation direction, and the maximum rotation angle of both the fixed rod and the telescopic mechanism is limited to 90 degrees by a limit block. A sliding sleeve is slidably mounted on the fixed end of the telescopic mechanism. When the fixed rod and the telescopic mechanism rotate to a parallel state with each other, the fixed rod and the telescopic mechanism are connected through the sliding sleeve. The sliding sleeve is provided with two chutes, one of which matches the size of the fixed end of the telescopic mechanism, and the other matches the size of the fixed rod. In the initial state, both the fixed rod and the telescopic mechanism are placed flat on the bottom plate of the box body, and the fixed rod and the telescopic mechanism are on the same straight line. In the working state, both the fixed rod and the telescopic mechanism are rotated around the hinge axis until they are perpendicular to the bottom plate. At this time, the fixed rod and the telescopic mechanism are arranged back-to-back and parallel to each other. Then, the sliding sleeve is slid so that the sliding sleeve is sleeved on both the fixed rod and the telescopic mechanism at the same time, thereby locking the position of the telescopic mechanism by using the fixed rod and ensuring that the telescopic mechanism maintains a state perpendicular to the bottom plate.

[0007] In this embodiment, the telescopic mechanism includes a manual telescopic rod, an electric telescopic rod, and a rotating rod. The bottom of the rotating rod is hinged to the bottom plate of the box body. The sliding sleeve is slidably mounted on the rotating rod. The bottom of the electric telescopic rod is coaxially fixed to the top of the rotating rod. The bottom of the manual telescopic rod is coaxially fixed to the top of the electric telescopic rod. The transmitting head is fixed to the top of the manual telescopic rod.

[0008] In this embodiment, the transmitting head is connected to the manual telescopic rod through a buffer structure. The buffer structure can provide buffering when the transmitting head contacts the bottom surface of the floor slab, prevent the transmitting head from being damaged, and extend the service life of the transmitting head. In this embodiment, the buffer structure uses a hard spring.

[0009] In this embodiment, a handle for convenient movement is provided on the receiver.

[0010] In this embodiment, a protective frame is also sleeved on the bottom of the signal receiving end of the receiver. Buffer rods are symmetrically fixed on the upper side of the protective frame. One end of the buffer rod is connected to the outer shell of the receiver, and the other end is connected to the protective frame. A tension spring is sleeved on the outer side of the buffer rod.

[0011] In this embodiment, walking wheels are installed on one side edge of the box body, and a handle is installed on the side of the box body opposite to the walking wheels. In the use state, the box body is placed flat on the ground, and the bottom plate of the box body is supported on the ground through a walking mechanism, and the walking wheels do not contact the ground. When the equipment is used up and needs to be transferred, after closing the box cover, the staff can pull the handle. At this time, the walking wheels contact the ground, and the walking wheels and the handle facilitate the staff to move the entire box body, making the floor thickness sensor more convenient to carry and improving the convenience of equipment use.

[0012] With the above structure, the device has the following advantages:

[0013] 1. The box body of this device can accommodate and move the telescopic mechanism and the transmitting head. The telescopic mechanism is used to conveniently support the transmitting head, reducing the manual labor during measurement. The walking mechanism and the rocker are used to conveniently remotely control the movement of the measurement position of the transmitting head. The camera and the display screen can observe the positions of the box body and the transmitting head during movement.

[0014] 2. The telescopic mechanism is installed in the box body by means of hinge. The detachable cover plate is convenient for accommodating the device when not in use, reducing its occupied space, avoiding bumps and dust. When in the working state, the telescopic mechanism and the bottom plate are locked in a relatively vertical state through the locking mechanism to ensure the stability of the transmitting head during operation.

[0015] 3. The buffer structure can ensure the support of the transmitting head while reducing the control accuracy required by the electric telescopic rod, protecting the transmitting head from excessive extrusion, and prolonging the service life of the electric telescopic rod.

[0016] 4. The cooperation between the protective frame on the receiver and the tension spring can protect the receiver during the left - right lateral movement of the receiver, reduce the wear of its bottom, and prolong its service life.

[0017] 5. The box body is also equipped with walking wheels and a handle, which is convenient for the staff to move the entire box body, making the floor thickness sensor more convenient to carry and improving the convenience of using the device.

[0018] In summary, this device can reduce the manual labor during measurement, reduce the measurement difficulty, save the time required for measurement, and facilitate the storage and turnover use of the device. Brief Description of the Drawings

[0029] Such as Figure 1-7As shown in the figure, a floor slab thickness measuring device includes a box body 1, a telescopic mechanism, a transmitting head 3 and a receiver 7 that matches the transmitting head 3. The receiver 7 is an independent structure, and a grip 6 for convenient movement is provided on the receiver 7. A traveling mechanism 5 is installed at the bottom of the box body 1. The top of the box body 1 is open, and a detachable box cover 23 is installed on the top opening of the box body 1. A card slot that matches the size of the telescopic mechanism is provided on the bottom plate inside the box body 1. The fixed end of the telescopic mechanism is hinged to the bottom plate of the box body 1, and the transmitting head 3 is installed on the telescopic end. On the bottom plate, a fixed rod 12 is also hinged on one side close to the fixed end of the telescopic mechanism. The fixed rod 12 rotates in the opposite direction to the telescopic mechanism, and the maximum rotation angle of both the fixed rod 12 and the telescopic mechanism is limited to 90 degrees by a limiting block. A sliding sleeve 15 is slidably installed on the fixed end of the telescopic mechanism. When the fixed rod 12 and the telescopic mechanism rotate to a parallel state with each other, the fixed rod 12 and the telescopic mechanism are connected through the sliding sleeve 15. Two sliding grooves are provided on the sliding sleeve 15. One sliding groove matches the size of the fixed end of the telescopic mechanism, and the other sliding groove matches the size of the fixed rod 12. In the initial state, the telescopic mechanism is clamped in the card slot, and both the fixed rod 12 and the telescopic mechanism are placed flat on the bottom plate, and the fixed rod 12 and the telescopic mechanism are on the same straight line. In the working state, both the fixed rod 12 and the telescopic mechanism are rotated around the hinge axis until they are perpendicular to the bottom plate. At this time, the fixed rod 12 and the telescopic mechanism are arranged back-to-back and parallel. Then, the sliding sleeve 15 is slid, and the sliding sleeve 15 is sleeved on the fixed rod 12 at the same time, so as to lock the position of the telescopic mechanism by using the fixed rod 12 and ensure that the telescopic mechanism maintains a state perpendicular to the bottom plate. Then, through the telescopic movement of the telescopic mechanism, the transmitting head 3 is pushed up to the bottom surface of the floor slab to be measured. The measuring personnel then hold the receiver 7 and move to the top surface of the floor slab to be measured, and place the receiver 7 at the corresponding position of the transmitting head 3 to realize the measurement of the floor slab thickness.

[0030] As Figure 1 , 3 , 5, 6 show that the telescopic mechanism includes a manual telescopic rod 2, an electric telescopic rod 10 and a rotating rod 11. The bottom of the rotating rod 11 is hinged to the bottom plate of the box body 1. The sliding sleeve 15 is slidably installed on the rotating rod 11. The bottom of the electric telescopic rod 10 is coaxially fixed to the top of the rotating rod 11. The bottom of the manual telescopic rod 2 is coaxially fixed to the top of the electric telescopic rod 10. The transmitting head 3 is fixed to the top of the manual telescopic rod 2. Further, the transmitting head 3 is connected to the manual telescopic rod 2 through a buffer structure. The buffer structure can provide buffering when the transmitting head 3 contacts the bottom surface of the floor slab, prevent the transmitting head 3 from being damaged, and extend the service life of the transmitting head 3. The limiting block includes a first limiting block 13 for limiting the rotating rod 11 and a second limiting block 14 for limiting the fixed rod 12. In this embodiment, the buffer structure uses a hard spring.

[0031] As Figure 2 , 7As shown, a camera 4 is installed on the transmitting head 3. The camera 4 is a dual-sided camera, and the dual-sided camera faces the upper and lower sides. The traveling mechanism 5 is driven by a motor to travel. A display screen 9, a first controller, a joystick 8, and control buttons 24 are also installed on the receiver 7. A second controller is installed on the box body 1. The display screen 9, the joystick 8, and the control buttons 24 are connected to the first controller. The camera 4, the electric telescopic rod 10, and the traveling mechanism 5 are connected to the second controller. The first controller and the second controller communicate with each other wirelessly. The display screen 9 is used to display the real-time shooting image of the camera 4. The control buttons 24 are used to control the opening and closing of the electric telescopic rod 10 and the traveling mechanism 5. The joystick 8 is used to control the moving direction of the traveling mechanism 5.

[0032] A protective frame 18 is also sleeved on the bottom of the signal receiving end of the receiver 7. Buffer rods 19 are symmetrically fixed on the upper side of the protective frame 18. One end of the buffer rod 19 is connected to the outer shell of the receiver 7, and the other end is connected to the protective frame 18. A tension spring 20 is sleeved on the outer side of the buffer rod 19.

[0033] When the receiver 7 is searching for the position of the transmitting head 3, the protective frame 18 makes the protector extend and the receiver 7 does not contact the floor slab. When the receiver 7 finds the signal of the transmitting head 3, the staff can press down to make the receiver 7 abut against the floor slab. The cooperation of the protective frame 18 and the tension spring 20 can protect the receiver 7 when it moves horizontally left and right, reduce the wear of its bottom, and extend its service life.

[0034] As Figure 1 、 4 shown, traveling wheels 21 are installed on one side edge of the box body 1, and a handle 22 is installed on the side of the box body 1 opposite to the traveling wheels 21. In the use state, the box body 1 is placed flat on the ground, and the bottom plate of the box body 1 is supported on the ground by the traveling mechanism 5, and the traveling wheels 21 do not contact the ground. When the equipment is used up and needs to be transferred, after covering the box cover 23, the staff can pull the handle 22. At this time, the traveling wheels 21 contact the ground. The traveling wheels 21 and the handle 22 facilitate the staff to move the entire box body 1, making the floor slab thickness sensor more convenient to carry and improving the convenience of equipment use.

[0035] When the utility model is in use, first move the box body 1 to the floor inside the floor under the floor slab to be detected, open the box cover 23, rotate both the fixing rod 12 and the rotating rod 11 around the hinge axis until they are perpendicular to the bottom plate. At this time, the fixing rod 12 and the rotating rod 11 are arranged parallel to each other back to back. Then slide the sliding sleeve 15 and simultaneously sleeved the sliding sleeve 15 on the fixing rod 12, so as to lock the position of the rotating rod 11 by using the fixing rod 12 and ensure that the rotating rod 11 remains perpendicular to the bottom plate. Then adjust the length of the manual telescopic rod 2 to make the transmitting head 3 close to the bottom of the floor slab. Then operate the control button 24 on the receiver 7 to control the telescopic movement of the electric telescopic rod 10, so that the transmitting head 3 can be in contact with the bottom surface of the floor slab. Subsequently, the measuring personnel drive the receiver 7 to the upper side of the floor slab by using the handle 6, and view the specific position of the transmitting head 3 through the display screen 9. Then press the receiver 7 tightly against the ground. When the receiver 7 is aligned with the transmitting head 3, the thickness of the floor slab at this point can be detected; when multiple test points need to be tested, operate the control button 24 to lower the electric telescopic rod 10, and then control the movement of the walking mechanism 5 to move the entire box body 1 through the rocker 8. Wait until the transmitting head 3 reaches the next specified detection position, and then control the electric telescopic rod 10 to rise so that the transmitting head 3 is in contact with the bottom of the floor slab, and so on; after the detection is completed, operate in the reverse direction, then install the telescopic mechanism in the card slot for fixation, cover the box cover 23, and the staff can pull the handle 22 to transfer the device by using the walking wheels 21 and the handle 22 to achieve turnover use.
