Description

Technical Field

[0001] The invention belongs to the technical field of building hollowing detection, and in particular relates to a device for repairing hollowing of light and heavy-loaded floors. Background Art

[0002] In industrial plants, logistics warehouses and other places, light-weight heavy-duty floors are often used to meet the load-bearing and use requirements. However, due to the influence of various factors such as construction quality, material characteristics, and use environment, the floor is prone to hollowing. Hollowing not only affects the flatness and aesthetics of the floor, but also reduces its load-bearing capacity and service life, and in serious cases may cause safety hazards.

[0003] CN218824091U is retrieved and disclosed as a device for repairing floor hollowing, including a trolley bracket, a first connecting shaft, a wheel, a first gear, a second gear, a second connecting shaft, a half gear, a hollowing hammer, a piston, a marking pen, a spring, a limit plate, a slider, a guide rail, an air pipe, and an air bag. The wheel drives the first gear to rotate while rolling, the first gear drives the second gear to rotate, and the second gear drives the half gear to rotate, so that the hollowing hammer moves up and down through the direct cooperation between the half gear and the hollowing hammer to determine the position of the terrazzo floor hollowing; by using the cooperation between the air bag and the air pipe, after the position of the terrazzo floor hollowing is determined, the air bag is squeezed so that the air pipe pushes the piston to contact the marking pen with the floor to leave a mark, and after the air bag is released, the spring drives the piston and the marking pen to return to their original positions, and the above process is repeated to mark the size and position of the floor hollowing, which is convenient for the subsequent repair of the terrazzo floor hollowing.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0040] Embodiment 1, as Figures 1 to 9 As shown, a device for repairing hollowing of light and heavy-loaded floors includes a support unit 100, a transposition detection unit 200 and a force storage striking unit 300.

[0041] The support unit 100 includes a support frame 101 , and four acoustic wave detectors 104 are installed at the bottom of the support frame 101 . The acoustic wave detectors 104 are prior art, and the working principle thereof will not be described in detail herein.

[0042] The transposition detection unit 200 includes a driven wheel 201, which is rotatably mounted at the bottom of the support frame 101. An eccentric protrusion 2012 is eccentrically mounted on the driven wheel 201. A push plate 202 is slidably mounted on the eccentric protrusion 2012, and the push plate 202 slides horizontally at the bottom of the support frame 101. A driving rack 203 is mounted on the push plate 202. A driving gear 2031 is meshed on the surface of the driving rack 203. A guide roller is mounted at the rotation center of the driving gear 2031. 204, and the guide roller 204 is rotatably mounted at the bottom of the support frame 101, the side wall of the guide roller 204 is sleeved with a collar 205, a notch 2051 is opened on the collar 205, a slope 2052 is set on one side of the notch 2051, a guide slider 2043 is slidably mounted on the guide roller 204, the side wall of the guide slider 2043 is slidably connected to the slope 2052, and a rocker 2045 is installed on the guide slider 2043; when the equipment as a whole moves on the floor surface, The driven wheel 201 can rotate synchronously, and the eccentric protrusion 2012 on the driven wheel 201 rotates continuously, thereby driving the push plate 202 to move left and right as a whole. During the movement of the push plate 202, the driving rack 203 can be driven to move. The movement of the driving rack 203 can eventually drive the driving gear 2031 and the guide roller 204 to rotate back and forth, and the guide slider 2043 on the guide roller 204 can swing left and right, so that after the driven wheel 201 rotates one circle, it can drive the guide slider 2043 to rotate left and right, and the guide slider 2043 can drive the power storage knocking unit 300 to rotate left and right twice, thereby increasing the frequency of knocking, and the guide slider 2043 slides along the inclined surface 2052 as a whole, and finally allows the guide slider 2043 to slide on the guide roller, ensuring that the knocking position corresponding to the power storage knocking unit 300 on the guide slider 2043 changes, thereby further increasing the knocking range and improving the detection efficiency.

[0043] The power storage knocking unit 300 includes a guide cover 301 and a knocking rod 302. The guide cover 301 is installed on the support frame 101. An arc surface 3011 is opened inside the guide cover 301. The distance from the arc surface 3011 to the center of the guide roller 204 is adapted to the distance from the end of the rocker arm 2045 to the center of the guide roller 204. The knocking rod 302 is rotatably connected to the rocker arm 2045, and a torsion spring 3023 is clamped at the rotatable connection between the knocking rod 302 and the rocker arm 2045. When the guide slider 2043 drives the rocker arm 2045 to rotate, the rocker arm 2045 can rotate to the arc surface inside the guide cover 301, and the knocking rod 302 on the side wall of the rocker arm 2045 will rotate ninety degrees at this time, thereby ensuring that the rocker arm 2045 can smoothly rotate to the other side, and the knocking rod 302 can automatically rotate the torsion spring 3023 after rotating, thereby achieving the purpose of accumulating force for the knocking rod 302. After the rocker arm 2045 rotates to the other side, the knocking rod 302 is separated from the arc surface 3011, and the knocking rod 302 is driven to rotate by the torsion spring 3023, and then knocks the floor. The knocking sound received by the ultrasonic detector 104 is used to determine whether the floor is in a hollow state, thereby achieving the purpose of detection.

[0044] like Figures 1 to 9 As shown, in a specific embodiment, a pair of fixed legs 102 and a movable leg 103 are installed on the support frame 101, and the pair of fixed legs 102 are symmetrically welded at the bottom of the support frame 101.

The movable leg 103 is installed at the bottom of the support frame 101, and a universal wheel 1031 is installed at the bottom of the movable leg 103. The universal wheel 1031 is convenient for later steering, and the universal wheel 1031 has a braking function for timely braking.

[0045] like Figures 1 to 9 As shown, further, a pair of push rods 1011 are installed on the support frame 101 close to the side of the moving leg 103, and the pair of push rods 1011 are inclined, and a handlebar 1012 is installed through the push rod 1011, and an anti-slip sleeve is provided on the surface of the handlebar 1012. A groove is opened on the support frame 101, and a guide cover 301 is installed inside the groove to facilitate pushing the push rod 1011 through the handlebar 1012. The push rod 1011 pushes the entire support frame 101 to slide under the drive of the auxiliary wheel 1021 and the universal wheel 1031, thereby achieving the effect of movement.

[0046] Embodiment 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 1 to 9As shown, a support seat 2011 is installed at the bottom of the support frame 101, and the bottom of the support seat 2011 is rotatably connected to the driven wheel 201.

A strip groove 2021 is provided on the surface of the push plate 202, and the inner wall of the strip groove 2021 is slidably connected to the side wall of the eccentric protrusion 2012. The distance from the eccentric protrusion 2012 to the rotation center of the driven wheel 201 is less than half the length of the strip groove 2021. The size requirements are used to ensure that the eccentric protrusion 2012 can slide smoothly in the strip groove 2021, and when the driven wheel 201 rotates on the support seat 2011, the position of the eccentric protrusion 2012 on the driven wheel 201 changes, and the eccentric protrusion 2012 can roll on the strip groove 2021, thereby pulling the push plate 202 with the strip groove 2021 to slide.

[0047] like Figures 1 to 9 As shown, in a specific embodiment, a T-shaped bracket 2024 is installed on the side wall of the support seat 2011, and a reset cover 2023 is installed on the T-shaped bracket 2024. A baffle 2026 is slidably arranged inside the reset cover 2023, and a reset spring 2025 is clamped between one end of the baffle 2026 and the inner wall of the reset cover 2023. The compression direction of the reset spring 2025 and the sliding direction of the baffle 2026 are both on the same straight line. A reset rod 2022 is installed on the other end of the baffle 2026, and the reset rod 2022 passes through the reset cover 2023, and the end of the reset rod 2022 is connected to the side wall of the push plate 202. When the push plate 202 slides, the reset rod 2022 on the side wall of the push plate 202 can slide inside the reset cover 2023, and the baffle 2026 at the end of the reset rod 2022 can compress the reset spring 2025, so that the reset operation can be facilitated later through the reset spring 2025. The reset rod 2022 slides inside the reset cover 2023 to ensure that the push plate 202 can only slide horizontally at this time, which can finally play a role of limiting.

[0048] like Figures 1 to 9 As shown, further, a guide seat 2041 is installed at the bottom of the support frame 101, and the guide seat 2041 is rotatably connected to the guide roller 204. A collar 205 is installed on the side wall of the guide seat 2041, and the driving gear 2031 is located above the driving rack 203. During the sliding process of the push plate 202, the driving rack 203 at the bottom of the push plate 202 can slide on the driving gear 2031, and the guide roller 204 coaxially connected to the driving gear 2031 rotates, and the guide roller 204 can rotate inside the guide seat 2041.

[0049] like Figures 1 to 9As shown, a horizontal guide slot 2042 is provided on the surface of the guide roller 204, a guide rod 2044 is installed in the guide slot 2042, a guide slider 2043 is installed on the guide slot 2042, the guide slider 2043 movably penetrates the guide rod 2044, a guide spring 2049 is sleeved on the outer wall of the guide rod 2044, one end of the guide spring 2049 is clamped on the side wall of the guide slot 2042, and the other end is clamped on the side wall of the guide slider 2043. The guide slider 2043 is placed in the notch 2051, and a side plate 2046 is installed on the side wall of the guide slider 2043, and a guide wheel 2047 is rotatably installed on the side plate 2046, and the outer wall of the guide wheel 2047 and the surface of the inclined surface 2052 are mutually attached. The surface of the notch 2051 is provided with a first flat groove 2053 and a second flat groove 2054, respectively. The first flat groove 2053 and the second flat groove 2054 are respectively connected to the two sides of the inclined surface 2052, and the inclined surface 2052 is spiral in shape. Fig. 9 As a reference), at this time, the driving gear 2031 and the guide roller 204 rotate counterclockwise, and the guide slider 2043 on the guide roller 204 rotates synchronously, and the side plate 2046 and the guide wheel 2047 at the end of the guide slider 2043 can slide alternately through the first flat groove 2053, the inclined surface 2052 and the second flat groove 2054 to ensure that the guide slider 2043 can rotate to the other side at this time, and then the knocking position at this time changes synchronously, and when the guide slider 2043 rotates to the other side, the guide slider 2043 can slide on the guide slide groove 2042 at this time, and the guide slider 2043 slides on the guide rod 2044 and compresses the guide spring 2049, so that the guide spring 2049 is used to facilitate the reset operation later.

[0050] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 1 to 9 As shown, further, a hollow hammer 3021 is installed at the end of the knocking rod 302, and the hollow hammer 3021 mainly serves the purpose of knocking. A rotating shaft 3022 is installed at the rotation center of the knocking rod 302, and the rotating shaft 3022 is rotatably connected to the end of the rocker arm 2045. A torsion spring 3023 is sleeved on the rotating shaft 3022, and one end of the torsion spring 3023 is clamped on the side wall of the rocker arm 2045, and the other end of the torsion spring 3023 is clamped on the side wall of the knocking rod 302. A rolling ball 2048 is installed at the end of the rocker arm 2045, and the rolling ball 2048 reduces the friction between the end of the rocker arm 2045 and the arc surface 3011.

[0051] The implementation principle of the device for repairing hollow drums on light and heavy-loaded floors in this embodiment is as follows:

[0052] First, the operator needs to place the entire device on the floor, and then the operator drives the entire device to move through the handle 1012 and the push rod 1011. The auxiliary wheels 1021 and the universal wheels 1031 on the device roll on the floor, and the driven wheels 201 at the bottom of the support frame 101 start to rotate synchronously at this time.

[0053] When the driven wheel 201 rotates on the support seat 2011, the position of the eccentric protrusion 2012 on the driven wheel 201 changes, and the eccentric protrusion 2012 can roll on the strip groove 2021, thereby pulling the push plate 202 with the strip groove 2021 to slide. When the push plate 202 slides, the reset rod 2022 on the side wall of the push plate 202 can slide inside the reset cover 2023, and the baffle 2026 at the end of the reset rod 2022 can compress the reset spring 2025, and the reset spring 2025 facilitates the reset operation later, and the reset rod 2022 slides inside the reset cover 2023, ensuring that the push plate 202 can only slide horizontally at this time, and finally plays a role of limiting.

[0054] During the sliding process of the push plate 202 , the driving rack 203 at the bottom of the push plate 202 can slide on the driving gear 2031 , and the guide roller 204 coaxially connected to the driving gear 2031 rotates, and the guide roller 204 can rotate inside the guide seat 2041 .

[0055] When the driving rack 203 slides to the right (with Fig. 9 As a reference), at this time, the driving gear 2031 and the guide roller 204 rotate counterclockwise, and the guide slider 2043 on the guide roller 204 rotates synchronously, and the side plate 2046 and the guide wheel 2047 at the end of the guide slider 2043 can slide alternately through the first flat groove 2053, the inclined surface 2052 and the second flat groove 2054 to ensure that the guide slider 2043 can rotate to the other side at this time, and then the knocking position at this time changes synchronously, and when the guide slider 2043 rotates to the other side, the guide slider 2043 can slide on the guide slide groove 2042 at this time, and the guide slider 2043 slides on the guide rod 2044 and compresses the guide spring 2049, so that the guide spring 2049 is used to facilitate the reset operation later.

[0056] When the guide slider 2043 drives the rocker arm 2045 to rotate, the rocker arm 2045 can rotate to the arc surface 3011 inside the guide cover 301, and the knocking rod 302 on the side wall of the rocker arm 2045 will rotate ninety degrees at this time, thereby ensuring that the rocker arm 2045 can smoothly rotate to the other side. After the knocking rod 302 rotates, the torsion spring 3023 can be automatically rotated, thereby achieving the purpose of accumulating force to knock the rod 302. During the rotation of the rocker arm 2045, the rolling ball 2048 can play a guiding role. When the rocker arm 2045 is completely rotated to the other side, the knocking rod 302 and the arc surface 3011 are separated, and the knocking rod 302 is driven to rotate by the torsion spring 3023. At this time, the hollow hammer 3021 can accelerate the knocking of the floor, and the knocking sound received by the acoustic wave detector 104 can be used to determine whether the floor is in a hollow state, thereby achieving the purpose of detection.

[0057] In summary, when the driven wheel 201 rotates one circle, the eccentric protrusion 2012 can drive the push plate 202 to move back and forth left and right, and then the push plate 202 drives the guide roller 204 to rotate left and right once by driving the rack 203, and the power storage knocking unit 300 on the guide roller 204 knocks once during the left and right rotation, which increases the frequency of knocking, and the knocking range of the power storage knocking unit 300 changes, which can increase the knocking range and further improve the efficiency of knocking detection.
