Description

Technical Field

[0001] The invention belongs to the technical field of construction disaster monitoring and early warning, and in particular is a construction site slope collapse warning device. Background Art

[0002] In the field of construction engineering, slope collapse is one of the main risks threatening construction safety. Therefore, slope collapse warning devices are usually installed at construction sites to monitor the stability of the slope in real time and promptly warn of collapse risks. In the existing technology, this device is usually composed of displacement sensors, tilt sensors, pressure sensors, etc., which can collect key data such as slope displacement, tilt angle, soil pressure, etc., and perform real-time analysis through the built-in microcontroller or Internet of Things module. Once an abnormal change is detected (such as displacement exceeding the limit or inclination intensifying), the system immediately triggers the on-site sound and light alarm, and simultaneously sends a warning message to the manager's mobile phone or monitoring platform.

[0003] However, in the field of slope engineering construction safety warning, traditional warning devices mostly use fixed-mounted sound and light alarms or static signs. Because such equipment is in a static state for a long time, it is easy to cause visual fatigue and habitual neglect among construction workers. Especially at long distances or in harsh environments, static warning signals are easily confused with ambient light, and the recognition is significantly reduced, making it difficult to alert construction workers in time, and it is difficult to meet the construction site's requirements for rapid response and dynamic warnings. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a construction site slope collapse warning device.

A spiral groove is provided on the outer side of the warning light, and one end of the guide block is slidably connected in the spiral groove.

[0008] In the above technical solution, preferably, it further comprises an elastic member provided on the mounting base and connected to the end of the straight plate; The elastic member includes an oblique rod rotatably connected to the end of the straight plate. The number of the oblique rods is the same as the straight plate. The other end of the oblique rod is connected to the same annular ring. The warning light is symmetrically fixed with a roller located above the annular ring.

[0009] In the above technical solution, preferably, an extension plate is provided on the frame of the roller, an annular groove is provided on the annular ring, a slider is provided for sliding in the annular groove, a guide column is provided on the slider with one end passing through the extension plate, and a tensioning spring is provided between the extension plate and the slider and is sleeved on the outside of the guide column.

[0010] In the above technical solution, preferably, the spiral groove includes a rotation displacement section and an unlocking section along the axial direction, wherein: When the guide block is in the rotation displacement section, the transmission member drives the polygonal rod to rotate alternately forward and reverse, driving the warning light to perform a spiral lifting motion; The tensioning spring tightens the annular ring, thereby driving the straight plate to move toward the central axis of the mounting base, thereby driving the abutment plate to further abut against the warning column; When the guide block is in the unlocking section, the transmission member continuously reverses to drive the warning light downward; The roller presses down the annular ring, thereby driving the straight plate to move away from the central axis of the mounting base, thereby releasing the abutment state between the warning light and the warning column.

[0011] In the above technical solution, preferably, the transmission part includes a motor, the output end of the motor is connected to the polygonal rod, an assembly hole is provided in the middle of the mounting base, the motor is fixed to the bottom end of the mounting base by bolts and is located below the assembly hole, and the motor is inserted into the top hole of the warning column.

[0012] In the above technical solution, preferably, it further includes a conical block provided at the bottom end of the motor, and the outer side of the conical block is provided with rubber inclined plates at equal intervals to abut against the hole of the warning column.

[0013] In the above technical solution, preferably, it also includes a turntable fixed on the polygonal rod and located above the assembly hole, and pull ropes are equidistantly provided on the side of the turntable close to the assembly hole. A through hole for the pull rope to pass through is opened on the mounting base, and the other end of the pull rope is connected to the rubber inclined plate. A positioning wheel is provided between the end of the rubber inclined plate and the central axis of the conical block, and the through end of the pull rope passes around the positioning wheel and is fixed to the end of the rubber inclined plate.

[0014] In the above technical solution, preferably, when the guide block is in the rotation displacement section, the motor drives the polygonal rod to rotate alternately in forward and reverse directions, driving the warning light to perform a spiral lifting motion; wherein the drawstring is in a relaxed state; When the guide block is in the unlocking section, the motor continuously reverses to drive the turntable to rotate and tighten the draw rope; The pull rope pulls the rubber inclined plate through the positioning wheel to shrink toward the central axis of the tapered block, thereby releasing the contact between the rubber inclined plate and the inner wall of the warning column hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention drives the warning light to reciprocate along the vertical spiral through the cooperation of the polygonal prism rod, guide rail, guide block and spiral groove in the spiral lifting part, forming a "rotating and flashing" dynamic warning effect. Compared with static warnings, it is easier to attract the visual attention of construction workers, especially at long distances and low visibility conditions. The regular changes in the motion trajectory can be quickly captured by construction workers, effectively alerting them.

[0016] Furthermore, the abutment plate can clamp the warning post under the elastic potential energy of the clamping spring, and the rubber inclined plate is inserted into the hole of the warning post to abut against it to achieve the fixation between the warning post and the warning light. The abutment plate is provided with multiple abutment modes (first abutment plate and clamping spring / second abutment plate and torsion spring) to adapt to the use of warning posts with different diameters. On the basis of the warning light realizing the warning, the device further has a roller that rotates together with the warning light and is linked with the elastic member. During the rotation displacement section, the elastic potential energy of the tensioning spring can tighten the inclined rod, further driving the abutment plate to press against the warning column, thereby strengthening the connection stability between the warning column and the warning light, and maintaining the stability of the device under complex environmental vibrations; During the unlocking process of the warning light, the pull rope further pulls the end of the rubber inclined plate inward and the roller pushes the annular ring downward in the opposite direction to drive the abutment plate to move outward, thereby simultaneously releasing the abutment between the warning column and the warning light.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 、 Figure 3 As shown, the present invention provides a construction site slope collapse warning device, comprising a warning post 1 and a mounting base 2 inserted into a top hole of the warning post 1, a warning light 3 being provided on the top of the mounting base 2, and further comprising: The spiral lifting member 4 is provided on the mounting base 2 and is used to drive the warning light 3 to move back and forth in a vertical spiral; The spiral lifting member 4 includes a transmission member 41, which is fixedly arranged on the mounting base 2. The output end of the transmission member 41 is provided with a polygonal column rod 42 to transmit its circumferential reciprocating rotation. The outer side of the polygonal column rod 42 is slidably connected to the warning light 3. The edge side of the mounting base 2 is fixedly connected to a symmetrically arranged guide rail 43, and a guide block 44 is slidably connected in the guide rail 43. A spiral groove 45 is provided on the outer side of the warning light 3, and one end of the guide block 44 is slidably connected in the spiral groove 45.

[0021] The transmission member 41 drives the polygonal rod 42 to rotate alternately in forward and reverse directions, driving the warning light 3 to perform a spiral lifting motion along the constrained path of the spiral groove 45 and the guide rail 43, forming a regular dynamic warning; at the same time, the guide block 44 slides in the spiral groove 45 to control the lifting height, and its spiral reciprocating motion forms a highly recognizable rotating dynamic warning light effect, which enhances the visual recognition of construction workers and effectively attracts their attention, solving the problem that traditional fixed lights are easily ignored in complex construction environments due to the lack of dynamic changes.

[0022] like Figure 2 、 Figure 4 and Figure 5 As shown, a straight plate 5 is provided at the bottom end of the mounting base 2 in an equidistant and symmetrical sliding manner, and a clamping spring 6 is fixedly connected to one side of the straight plate 5 close to the central axis of the mounting base 2. The other end of the clamping spring 6 is fixedly connected to the bottom end of the mounting base 2, and an abutment plate 7 is provided on the straight plate 5 to press against the warning column 1 under the elastic potential energy of the clamping spring 6.

[0023] The abutment plate 7 includes a first abutment plate 71 arranged on the straight plate 5, and a receiving hole 72 is opened on the first abutment plate 71. A second abutment plate 73 is rotatably arranged in the receiving hole 72. A torsion spring 74 is provided between the second abutment plate 73 and the inner wall of the receiving hole 72. A baffle 75 is provided on the side of the first abutment plate 71 away from the central axis of the mounting base 2 to limit the circumferential rotation angle of the second abutment plate 73.

[0024] The straight plate 5 drives the abutment plate 7 to cling to the inner wall of the warning column 1 under the elastic retraction force of the clamping spring 6. The first abutment plate 71 provides basic support, and the second abutment plate 73 adaptively rotates to fit the column surface through the torsion spring 74, which can be used to adapt to warning columns 1 of various sizes. It also includes a tightening member 8 provided on the mounting base 2 and connected to the end of the straight plate 5; The elastic member 8 includes an inclined rod 81 rotatably connected to the end of the straight plate 5. The number of the inclined rods 81 is the same as the straight plate 5. The other end of the inclined rod 81 is connected to the same annular ring 82. The warning light 3 is symmetrically fixed with a roller 83 located above the annular ring 82.

[0025] At the same time, when the warning light 3 is raised or lowered, the roller 83 presses down or releases the annular ring 82 with the spiral motion, and the straight plate 5 is linked to expand or retract through the inclined rod 81, thereby achieving the effect of "the clamping spring 6 automatically increases force and locks when raising or lowering, and the roller 83 presses down and loosens when releasing".

[0026] like Figure 4 、 Figure 6 As shown, an extension plate 9 is provided on the frame of the roller 83, an annular groove 10 is provided on the annular ring 82, a slider 11 is provided slidingly in the annular groove 10, a guide column 12 is provided on the slider 11, one end of which passes through the extension plate 9, and a tensioning spring 13 is provided between the extension plate 9 and the slider 11 and is sleeved on the outside of the guide column 12.

[0027] When the guide block 44 is in the rotation displacement section 451, the warning light 3 spirally rises and falls, triggering the tensioning spring 13 to tighten the annular ring 82, and the linked inclined rod 81 forces the straight plate 5 to retract, thereby increasing the clamping force of the abutment plate 7 on the warning column 1; like Figure 3 As shown, the spiral groove 45 includes a rotation displacement section 451 and a unlocking section 452 along the axial direction, wherein: When the guide block 44 is in the rotation displacement section 451, the transmission member 41 drives the polygonal rod 42 to rotate alternately in forward and reverse directions, driving the warning light 3 to perform a spiral lifting motion; The tensioning spring 13 tightens the annular ring 82, thereby driving the straight plate 5 to move closer to the central axis of the mounting base 2, and driving the abutting plate 7 to further abut against the warning column 1; When the guide block 44 is in the unlocking section 452, the transmission member 41 continues to reverse and drives the warning light 3 downward; The roller 83 presses down the annular ring 82 , thereby driving the straight plate 5 to move away from the central axis of the mounting base 2 , thereby releasing the abutment state between the warning light 3 and the warning column 1 .

[0028] During the dynamic lifting and lowering process of the warning light 3, the clamping stability is automatically enhanced through mechanical linkage to avoid loosening due to vibration; when releasing, only the warning light 3 needs to be moved downward to unlock all clamping points with one click. It is easy to operate and suitable for construction scenarios with frequent installation / disassembly.

[0029] like Figure 3 、 Figure 7 、 Figure 8 As shown, the transmission member 41 includes a motor 411, the output end of the motor 411 is connected to the polygonal rod 42, an assembly hole is provided in the middle of the mounting base 2, the motor 411 is fixed to the bottom end of the mounting base 2 by bolts and is located below the assembly hole, and the motor 411 is inserted into the top hole of the warning column 1.

[0030] The electric motor 411 further includes a conical block 14 disposed at the bottom end thereof. Rubber inclined plates 15 are equidistantly disposed on the outer side of the conical block 14 and abut against the hole in the warning column 1 .

[0031] The elastic deformation of the rubber material adaptively fits different hole diameters to form radial friction reinforcement; at the same time, the rubber inclined plate 15 offsets the vibration impact through elastic abutment, and cooperates with the stable guiding effect of the conical block 14 and the motor 411 to achieve bolt-free rapid installation and high vibration resistance in the hole.

[0032] It also includes a turntable 16 fixed on the polygonal rod 42 and located above the assembly hole. Pull ropes 17 are equidistantly provided on one side of the turntable 16 close to the assembly hole. A through hole 18 is provided on the mounting base 2 for the pull rope 17 to pass through. The other end of the pull rope 17 is connected to the rubber inclined plate 15. A positioning wheel 19 is provided between the end of the rubber inclined plate 15 and the central axis of the conical block 14. The through end of the pull rope 17 passes around the positioning wheel 19 and is fixed to the end of the rubber inclined plate 15.

[0033] When the guide block 44 is in the rotation displacement section 451, the motor 411 drives the polygonal rod 42 to rotate alternately in forward and reverse directions, driving the warning light 3 to perform a spiral lifting motion; Wherein, the drawstring 17 is in a relaxed state; The state of the pull rope 17 mainly ensures that the rubber inclined plate 15 maintains the expanded state to fix the warning column 1; When the guide block 44 is in the unlocking section 452 , the motor 411 continuously reverses to drive the turntable 16 to rotate and tighten the drawstring 17 ; The pull rope 17 pulls the rubber inclined plate 15 through the positioning wheel 19 to shrink toward the central axis of the tapered block 14 , thereby releasing the contact between the rubber inclined plate 15 and the inner wall of the hole of the warning column 1 .

[0034] During the above-mentioned release operation, the rubber inclined plate 15 can be synchronously retracted by only reversing the motor 411 without manual intervention, thereby greatly improving the disassembly efficiency.

[0035] The working principle and use process of the present invention: Select a stable surface near the area at risk of slope collapse, ensure that the warning post 1 does not shake noticeably after being vertically inserted, push the straight plate 5 away from the central axis of the mounting base 2, and insert the motor 411, the conical block 14, and the rubber bevel 15 at the bottom end of the mounting base 2 into the hole at the top of the warning post 1. The rubber bevel 15 presses against the inner wall of the hole in the warning post 1. Then, the abutment plates 7 (first abutment plate 71 and second abutment plate 73) can clamp the warning post 1 under the elastic potential energy of the clamping spring 6 and the torsion spring 74, thus completing the installation process of the warning post 1 and the warning light 3. In the warning mode, the motor 411 drives the polygonal rod 42 to rotate. When the guide block 44 slides along the rotation displacement section 451 of the spiral groove 45, the warning light 3 rises and falls along the vertical spiral, forming a dynamic rotating warning effect. The roller 83 rotates with the warning light 3, pulling up the tensioning spring 13, thereby tightening the inclined rod 81 through the annular ring 82, driving the straight plate 5 and the abutting plate 7 to further clamp the warning column 1. During this process, the pull rope 17 is in a relaxed state and is repeatedly wound in the forward / reverse direction between the turntable 16 and the mounting base 2, and the pull rope 17 does not become tangled due to the position restriction of the through hole 18; After the warning operation is completed, the motor 411 drives the polygonal rod 42 to rotate. When the guide block 44 slides along the unlocking section 452 of the spiral groove 45, the roller 83 presses down the annular ring 82, and the inclined rod 81 drives the straight plate 5 to move outward, and the abutment plate 7 releases the clamping of the warning column 1. The synchronous pull rope 17 is wound from a relaxed state to a tightened rubber inclined plate 15 state, and pulls the rubber inclined plate 15 to shrink toward the conical block 14, releasing the fixation in the hole of the warning column 1, and completing the release operation.
