DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment.

[0031] The civil engineering hollow detection equipment provided in the embodiment is mainly used for solving the problem that the height adjustment of the existing detection equipment is limited and the flexibility of the adjustment is poor when the wall surface is detected, thereby affecting the practicability, and provides the following technical scheme, which will be described below in combination with the drawings Figures 1-10Make a detailed description:

[0032] A civil hollow detection device, comprising:

[0033] The car plate 1 comprises a plate body, and universal self-locking wheels are arranged at the bottom of the four corners of the plate body. The car plate 1 can move on the ground, facilitating replacement of detection positions. A lifting rod 3 is mounted on the car plate 1 through a fixing piece 2. The lifting rod 3 comprises a plurality of vertical rods 301 connected in sequence. A rack 302 is arranged on one side of the vertical rod 301. Preferably, the racks 302 on the adjacent two vertical rods 301 can be butted to form a long rack belt. The number of vertical rods 301 can be increased or decreased according to the height of the wall surface, so that the overall height of the lifting rod 3 conforms to the height of the wall surface.

[0034] The climbing piece 4 comprises a frame plate 401 movably sleeved on one of the vertical rods 301. A frame slot is formed through the frame plate 401. The vertical rod 301 movably penetrates the frame slot. An axle rod 402 is rotatably penetrated through the frame plate 401. A gear 403 meshed with the teeth of the rack 302 is fixed on the axle rod 402. One end of the axle rod 402 is connected with a first motor 404 arranged on the frame plate 401. When the frame plate 401 is movably sleeved on the vertical rod 301, the gear 403 is in a tooth meshing state with the rack 302. The first motor 404 works, and the output shaft drives the axle rod 402 to rotate. Since the rack 302 is meshed with the teeth of the gear 403, the rack 302 is fixed and cannot move. Therefore, the frame plate 401 is driven to move. The first motor 404 rotates forward or reversely (preferably, the first motor 404 adopts a direct current motor, and the armature adopts a salient pole, so that the first motor 404 has a certain self-locking torque. The self-locking torque provided by the first motor 404 can overcome the weight of the climbing piece 4 as a whole, so as to ensure that the climbing piece as a whole can stably climb). Thus, the frame plate 401 is lifted and lowered. Preferably, a power supply is arranged on the car plate 1. The first motor 404 is connected with the power supply through wires, so that the first motor 404 can normally work after the frame plate 401 is lifted and lowered.

[0035] The knocking piece 5 comprises a sleeve 501 arranged on the frame plate 401. A knocking rod 502 is slidably inserted into the sleeve 501. A driving piece 503 is arranged on the frame plate 401 to drive the knocking rod 502 to reciprocate. When the frame plate 401 is lifted and lowered to a suitable height (the actual detection position of the wall surface) along the lifting rod 3, the knocking rod 502 is driven to reciprocate by the driving piece 503. The knocking rod 502 will knock the wall surface. When the wall surface is hollow, it will produce a sound. Whether the wall surface is hollow is judged according to the sound, so as to realize hollow detection of the wall surface.

[0036] In the scheme, the car plate 1 is first moved to the position close to the wall surface, and then the number of vertical rods 301 is increased or decreased according to the height of the wall surface, and a plurality of vertical rods 301 are sequentially connected to form a lifting rod 3, so that the height of the lifting rod 3 is adapted to the height of the wall surface, the first motor 404 works to drive the frame plate 401 to ascend and descend, and then the driving member 503 drives the knocking rod 502 to reciprocatingly slide and knock the wall surface, so as to detect the hollow of the wall surface, and the hollow of the wall surface of different heights can be detected, thereby improving the practicability.

[0037] As shown in Figure 10 , in the embodiment, the driving member 503 includes a second motor 5031 arranged on the frame plate 401, the output shaft of the second motor 5031 is fixedly provided with a disc 5032, the disc 5032 is eccentrically hinged with a support rod 5033, the free end of the support rod 5033 is hinged with the knocking rod 502, the second motor 5031 works, and the output shaft drives the disc 5032 to rotate. Since the support rod 5033 is eccentrically hinged with the disc 5032, when the disc 5032 rotates, the support rod 5033 is driven to make a circular motion, so that the support rod 5033 pulls or abuts against the knocking rod 502, thereby making the knocking rod 502 reciprocatingly slide to knock the wall surface and detect the hollow.

[0038] As shown in Figure 10 , in the embodiment, the inner wall of the sleeve 501 is connected with a sleeve 6 through a connecting rod. Preferably, the sleeve 6 is coaxially arranged with the sleeve 501, and the sleeve 6 and the sleeve 501 have an annular gap therebetween. The knocking rod 502 slides through the sleeve 6. The sleeve 501 is provided with a through slot 7. The knocking rod 502 is connected with a guide rod 8 which slides through the through slot 7. The end of the support rod 5033 away from the disc 5032 is hinged with the guide rod 8. One end of the sleeve 501 is provided with a loudspeaker 9. When the hollow of the wall surface is detected, the end of the sleeve 501 is close to the wall surface. When the knocking rod 502 knocks the wall surface, the sound of knocking is transmitted into the sleeve 501. By arranging the loudspeaker 9, the sound of knocking the wall surface is amplified, so that the sound of knocking the wall surface is more clearly heard when the hollow of the high part of the wall surface is detected, so as to better judge whether the wall surface is hollow or not, thereby improving the practicability.

[0039] As shown in Figure 10 , in the embodiment, the end of the sleeve 501 away from the loudspeaker 9 is communicated with a conical sleeve 10. One end of the knocking rod 502 is connected with a conical head 11. Preferably, the conical sleeve 10 and the conical head 11 are made of rubber material. By arranging the conical sleeve 10 and the conical head 11, the conical sleeve 10 can be attached to the wall surface when the hollow is detected, so that the sound of knocking the wall surface can be effectively amplified through the loudspeaker 9, and the wall surface can also be protected from being damaged by the knocking rod 502.

Since the vertical rod 301 is vertically arranged, the plug-in block 13 at one end of the vertical rod 301 is plugged into the plug-in slot 12 on the adjacent vertical rod 301, and under the action of gravity, the two adjacent vertical rods 301 are connected to form a lifting rod 3.

Preferably, the clamping groove 14 is a V-shaped groove, and the end of the clamping block 16 is V-shaped. After the plug-in block 13 is plugged into the plug-in slot 12 by applying a certain force, the two clamping blocks 16 are respectively clamped in the two clamping grooves 14 under the elastic resistance of the spring 17, thereby improving the stability of the connection between the two adjacent vertical rods 301. When it is necessary to disconnect the two vertical rods 301, a certain force is applied, and the clamping block 16 is separated from the clamping groove 14 by using the resistance of the V-shaped slope of the clamping groove 14 and the clamping block 16, thereby achieving disconnection.

[0042] As Figure 6 shown, in this embodiment, the vertical rod 301 is provided with a recess 18 on the side away from the rack 302, and the frame plate 401 is provided with a limiting wheel 19 rotatably arranged, and the limiting wheel 19 is rotatably inserted into the recess 18. By providing the recess 18 on the vertical rod 301 and the limiting wheel 19 rotatably inserted into the recess 18 on the frame plate 401, the limiting wheel 19 and the gear 403 respectively roll and resist on the opposite sides, which can not only ensure the stable lifting of the frame plate 401, but also reduce the frictional resistance, thereby improving the practicability.

[0043] As Figure 7 shown, in this embodiment, the fixing member 2 includes an installation cylinder 201 arranged on the vehicle plate 1, a threaded rod 202 threaded through one side of the installation cylinder 201, and a pressing plate 203 rotatably connected to the end of the threaded rod 202. After connecting several vertical rods 301 to form a lifting rod 3, the lifting rod 3 is plugged into the installation cylinder 201, and the threaded rod 202 is twisted to rotate and move, thereby driving the pressing plate 203 to press and resist the lifting rod 3, and using the resistance friction to achieve the effect of fixing the lifting rod 3.

[0044] The working procedure of the utility model is as follows: first, the car plate 1 is moved to the position close to the wall surface, then the number of the vertical rods 301 is increased or decreased according to the height of the wall surface, a plurality of vertical rods 301 are sequentially connected to form a lifting rod 3, the height of the lifting rod 3 is adapted to the height of the wall surface, the frame plate 401 is sleeved on the lifting rod 3, the first motor 404 works to drive the frame plate 401 to ascend and descend, the frame plate 401 is adjusted to the appropriate height, the knocking rod 502 reciprocatingly slides and knocks the wall surface through the driving of the driving part 503, the sound emitted by the knocking rod 502 knocking the wall surface is judged to detect the hollow of the wall surface, the lifting rod 3 is sequentially connected by a plurality of vertical rods 301, the number of the vertical rods 301 can be increased or decreased to change the height of the lifting rod 3, the hollow of the wall surface of different heights can be detected, and thus the practicability is improved.
