Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar hoisting, and particularly relates to an anti-collision device for hoisting a cable tower steel bar cage. Background Art

[0002] Most of the existing anti-collision devices for hoisting cable tower steel bar cages use radar sensors for detection. Millimeter wave radar sensors use millimeter waves. The wavelength of millimeter waves is between centimeter waves and light waves. Therefore, millimeter waves have the advantages of both microwave guidance and optoelectronic guidance. Compared with centimeter wave radar, millimeter wave radar has the characteristics of small size, easy integration and high spatial resolution. Compared with optical sensors such as cameras, infrared and lasers, millimeter wave radar has strong ability to penetrate fog, smoke and dust, strong anti-interference ability, and has the characteristics of all-weather and all-time.

[0003] The Chinese utility model patent with the patent announcement number CN214734018U and the announcement date of November 16, 2021 discloses an anti-collision device for tower cranes, including a reinforced concrete tower base. The upper end of the reinforced concrete tower base is provided with a tower frame. The upper end of the tower frame is provided with a rotating unit. Above the rotating unit is installed a boom. One side of the boom is provided with a cab. Inside the cab are installed a PLC console, a wireless data transmission module, a split screen display and an alarm. The upper end of the boom is provided with a GPS positioning module. The rear end of the boom is provided with a counterweight boom. A control cabinet is installed on the counterweight boom. The front end of the boom is provided with a working arm. A luffing trolley is installed at the lower end of the working arm. An anti-collision mechanism is installed on the outer wall at one end of the working arm. Protective lidar sensors are installed on both sides of the anti-collision mechanism. A three-eye camera is arranged below one end of the anti-collision mechanism.

[0004] The general usage method and advantages of the anti-collision device for tower cranes in the Chinese utility model patent are as follows: The GPS positioning module wirelessly transmits the positions of each tower crane on the construction site to the terminal. When the terminal detects that the working radii of two groups of cranes are tangent, a signal is sent to the PLC consoles of the two groups of cranes to drive the anti-collision system to operate. During operation, multiple groups of protective lidar sensors on both sides of the anti-collision mechanism can detect in real time whether there is an obstruction within the safe distance. When the working arm driven by the rotating unit approaches the working arm of another group of cranes during operation, if it is less than the preset safe distance of the protective lidar sensor, a signal will be sent to the PLC console. The control cabinet drives the motor controller and the alarm, so that the motor of the rotating unit brakes and stops further turning, and an alarm prompt is given to the staff in the cab to achieve the anti-collision effect. The advantage is that there is no need to map and upload the on-site image information through a camera to the computer and then rely on algorithms to calculate and issue commands for control, effectively preventing external impacts, and the anti-collision braking method is more efficient and flexible.

[0005] However, during actual use, the anti-collision device for tower crane still has at least the following shortcomings, in other words, which are the technical problems to be solved by the present invention: although the anti-collision device can effectively warn of the occurrence of a collision through sensors, radar sensors have problems such as regular maintenance, calibration, and limited life, and are inconvenient to install and disassemble, making them inconvenient to replace.

[0006] Therefore, in summary, there is an urgent need for an anti-collision device that is more convenient for later maintenance and replacement to solve the problem of such problems. Utility Model Content

[0032] In this embodiment, the general usage method of the anti-collision device is as follows:

[0033] On the crane, multiple sets of anti-collision devices can be set according to the actual situation. In each set, the mounting plate 1 is fixed on the crane for mounting the radar sensor 2 and the locking unit 3. The locking unit 3 ensures the stability of the radar sensor 2 in its initial state and is easy to disassemble to facilitate later maintenance, calibration, or timely replacement in case of damage. Specifically, the locking unit 3 includes a clamping component 31 for connecting the mounting plate 1 and the radar sensor 2 to fix the mounting position of the radar sensor. An active component 32 is provided at a position on the side of the mounting plate 1 close to the radar sensor 2. A fixed claw 33 is fixedly connected to the active component 22. The fixed claw 33 clamps the surface of the radar sensor 2 to prevent the radar sensor from shaking left and right, further stabilizing the position of the sensor to ensure the accuracy of anti-collision warning. The driving component 34 is also mounted on the mounting plate 1 and drives the active component 32 to rotate, so that the fixed claw 33 is locked or separated from the radar sensor 2, facilitating the removal of the radar sensor 2. Further, to prevent the device from being impacted in case of ineffective warning, a protection frame unit 4 for preventing impact can also be provided on the mounting plate 1. The protection frame unit includes legs 41 provided on the mounting plate, a baffle 42 provided on the legs, and an anti-collision layer 43 provided on the outer surfaces of the baffle and the legs.

[0034] As a preference of this embodiment, the clamping component 31 includes a clamping seat 311 provided on the mounting plate 1, and a clamping buckle 312 provided on the surface of the radar sensor 2 close to the mounting plate 1 and clamped with the clamping seat 311. The active component 32 includes a support seat 321 provided on the mounting plate 1, and a rotating rod 322 rotatably provided on the support seat 321 and parallel to the radar sensor 2. The fixed claw 33 is mounted on the rotating rod 322. The fixed claw 33 includes a claw body 331 and a convex rib 332 provided on the surface of the radar sensor 2 away from the mounting plate 1.

[0035] In this embodiment, the specific structures of a clamping component 31, a movable component 32, and a fixing claw 33 are disclosed; the clamping component 31 is composed of two parts, including a clamping seat 311 provided on the mounting plate 1 and a clamping buckle 312 provided on the surface of the radar sensor 2 close to the mounting plate 1. The clamping seat 311 is a U-shaped plate with both ends connected to the mounting plate 1, and together with the mounting plate, it forms a through groove for inserting the clamping buckle. The clamping buckle 312 is an L-shaped plate provided on the radar sensor 2. Preferably, a clamping notch is provided at the end of the plate. The L-shaped plate is inserted into the through groove to realize the connection of the clamping component 31; the movable component 32 mainly moves by rotating a rotating rod 322 for mounting the fixing claw 33. The support seat 321 is used to support the rotating rod 322 at a certain distance away from the mounting plate 1 so that the fixing claw 33 can smoothly clamp the radar sensor 2; the fixing claw 33 includes a claw body 331 fixedly connected to the rotating rod 322 and a convex rib 332 installed at the four corners of the radar sensor 2. There are multiple protrusions at the end of the claw body 331 to buckle the convex rib, and an anti-slip layer is provided on the protrusions to further fix the radar sensor 2 and prevent the radar sensor 2 from shifting during operation, causing detection deviation.

[0036] As a preference of this embodiment, the driving component 34 includes a motor provided on the mounting plate 1 and connected to the rotating rod 322.

[0037] In this embodiment, the driving component 34 is a rotating motor. The motor drives the rotating rod 322 to rotate clockwise / counterclockwise to realize the locking / separation between the fixing claw 33 and the radar sensor 2.

[0038] Embodiment Two

[0039] The difference between this embodiment and Embodiment One lies in the different driving components, specifically as follows: the rotating rod 322 is threadedly connected to the support seat 321.

[0040] In this embodiment, by an operator rotating the rotating rod 322, the locking or separation between the fixing claw 33 and the radar sensor 2 is realized.

[0041] Embodiment Three

[0042] The difference between this embodiment and Embodiments One and Two lies in the different structures of the driving components, specifically as follows:

[0043] As a preference of this embodiment, the driving component 34 includes a gear 341 provided at one end of the rotating rod 322, a chute 342 provided on the mounting plate 1, a rack 343 slidably connected in the chute 342 and meshing with the gear 341, a pull plate 344 provided at the side end of the rack 343, and a driving member 345 provided on the mounting plate 1 and driving the displacement of the pull plate 344.

[0044] In this embodiment, the sliding groove 342 is disposed perpendicular to the axial direction of the rotating rod 322 at the side end of the rotating rod 322. The smooth surface of the rack 343 is slidably connected to the sliding groove 342. The toothed surface of the rack 343 meshes with the gear 341. The gear 341 is disposed on the rotating rod 322 to drive the rotating rod 322 to rotate. A pulling plate 344 is disposed at the end of the rack 343. The driving member 345 drives the pulling plate 344 to move up and down, thereby driving the rack 343 to slide up and down in the sliding groove 342, and thus driving the gear 341 to rotate clockwise / counterclockwise to separate / lock the relationship between the fixed claw 33 and the radar sensor 2.

[0045] The driving member 345 includes a cylinder disposed on the mounting plate 1 and connected to the pulling plate 344;

[0046] In this embodiment, the driving of the pulling plate 344 is achieved by the contraction of the cylinder, thereby driving the rotating rod to rotate.

[0047] The driving member 345 includes a support plate 3451 disposed on the mounting plate 1 and parallel to the pulling plate 344, a pull rod 3452 disposed on the pulling plate 344 and passing through the support plate 3451, a spring 3453 sleeved outside the pull rod 3452 and located between the pulling plate 344 and the support plate 3451, and a handle 3454 disposed at the end of the pull rod 3452 away from the pulling plate 344.

[0048] In this embodiment, the support plate 3451 is fixedly connected to the mounting plate 1 and parallel to the pulling plate 344. A through hole is formed in the support plate 3451 for passing through the pull rod 3452. The upper end of the pull rod 3452 is connected to the pulling plate 344. The spring 3453 is sleeved on a section of the pull rod 3452 located between the support plate 3451 and the pulling plate 344. On the one hand, it is used to support the stability of the pulling plate when no external force is applied. On the other hand, when the pull rod 3452 is pulled downward, the spring 3453 has the effect of automatically returning the pulling plate 344 to the initial position when the external force disappears; in the initial state, the fixed claw 33 is fastened to the radar sensor 2, and in the pulling state, the fixed claw 33 is separated from the radar sensor 2. The handle 3454 is preferably disposed at the bottom end of the pull rod 3452 and exposed on the side of the mounting plate 1, so that the operator can directly operate from the back of the mounting plate to remove the radar sensor.

[0049] Compared with the prior art, the advantages of the technical solution of the present application are as follows: The radar sensor in the anti-collision device described in the present application has the characteristics of easy replacement and convenient maintenance. Sensors often need to be calibrated, debugged, etc. in daily use to ensure their accuracy, and the existing anti-collision devices have not optimized this.

[0050] The working process of the present utility model: When the radar sensor is damaged or needs to be removed for maintenance, first pull the pull rod downward. When the pull rod moves downward, it drives the pull plate to move downward. The pull plate drives the rack to move downward. Since the connection between the gear and the rack is a meshing connection, the rack is driven to drive the gear to rotate when moving. When the gear rotates, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the fixed claw to rotate. After the fixed claw rotates outward, the sensor is unlocked. Pulling the radar sensor upward can disassemble it, and reverse operation can install it, which is relatively convenient to operate.

[0051] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the gist of the present utility model. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present utility model.
