Abstract
Description
Technical Field
[0001] This utility model relates to a control device, and more particularly to a control device for a tower crane trolley used in zero-carbon building construction based on UWB technology. Background Technology
[0002] A tower crane trolley is a moving component mounted on the horizontal jib of a tower crane, used to move back and forth along the jib to lift and transport building materials. It is a key mechanical component enabling the tower crane to precisely move heavy objects at different locations, thereby improving construction efficiency and flexibility. UWB (Ultra-Wideband) technology, due to its high-precision positioning capabilities and low latency, has been widely used in industrial fields. Applying UWB technology to the tower crane trolley control system can significantly improve its positioning accuracy and safety, while reducing manual intervention and improving overall work efficiency.
[0003] The existing connection between the tower crane trolley and the horizontal boom is relatively simple. If the wheels malfunction or the guide rails malfunction, the trolley may fall from a height, causing a serious safety accident. In the event of a malfunction, there is a lack of effective emergency braking measures to quickly stabilize the trolley and prevent it from continuing to slide or fall. Utility Model Content
[0004] In order to overcome the shortcomings of existing tower crane trolleys lacking effective emergency braking measures between the trolley and the tower, the purpose of this utility model is to provide a tower crane trolley control device for zero-carbon building construction based on UWB technology.
[0005] The technical solution of this utility model is: a control device for a tower crane trolley for zero-carbon building construction based on UWB technology, including a connecting platform, a support frame, and a tower crane trolley. The support frame is connected to the upper right end of the connecting platform, and the tower crane trolley is slidably connected to the support frame. The tower crane trolley includes a moving frame, wheels, retractable wheels, a connecting frame, a connecting plate, a clamping block, and a positioning label. Wheels are symmetrically arranged on both the front and rear sides of the upper part of the moving frame, and the wheels are in contact with the support frame. Retractable wheels are rotatably connected to both the left and right sides of the middle of the moving frame. A positioning label is provided at the front end of the moving frame near the retractable wheels. A connecting frame is provided on both the front and rear sides of the moving frame, and a connecting plate is slidably connected inside the connecting frame. The upper part of the connecting plate is close to the support frame. A clamping block is slidably connected to the side of the two connecting frames that are close to each other, and the connecting plate and the clamping block are in contact with each other.
[0006] Furthermore, it also includes a winding machine and pulley blocks. Pulley blocks are symmetrically arranged on both the left and right sides of the support frame. The winding machine includes a bracket, a drum, a rotary motor, and a wire rope. A bracket is provided on the support frame, and a rotary motor is provided at the rear end of the bracket. Drums are symmetrically rotated on the bracket. The drums are connected to the output shaft of the rotary motor. A wire rope is wound around the outside of the drum. The wire rope passes through the pulley block on one side of the support frame to the lower part of the support frame, where it slides with the take-up and undo wheels and finally returns to the drum.
[0007] Furthermore, it also includes a controller, a drive motor, and a gear set. The controller is located at the top front of the connecting platform, the drive motor is located at the top front of the connecting platform, and the gear set is located at the bottom of the connecting platform. The output shaft of the drive motor is connected to the gear set, and both the drive motor and the rotary motor are connected to the controller by wires.
[0008] Furthermore, it also includes inspection frames, with inspection frames provided on both the front and rear sides of the mobile frame.
[0009] Furthermore, the upper part of the connecting plate is a rectangular plate, and the lower part is an inclined plate. The end of the inclined plate that contacts the clamping block is an inclined surface.
[0010] Furthermore, a groove is provided in the middle of the end of the clamping block near the connecting frame, and the groove is adapted to the inclined surface on the inclined plate.
[0011] Furthermore, it also includes elastic elements, with elastic elements connected to both the left and right sides of the connecting frame and the clamping block.
[0012] Compared with the prior art, this utility model has the following advantages: 1. By designing connecting frames and other components on the mobile frame, when the wheels of the tower crane trolley malfunction and fall off, the connecting plate will directly contact the support frame and bear the weight, preventing the trolley from falling off the support frame. The design of the clamping block can automatically clamp the rails in emergency situations, further improving the safety of the system.
[0013] 2. By setting up positioning tags on the tower crane trolley and deploying UWB base stations at the construction site, precise positioning can be achieved. The controller can flexibly adjust the position of the tower crane trolley based on the location data provided by the UWB base stations, allowing the tower crane trolley to quickly approach the operator, greatly improving work efficiency.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] A zero-carbon tower crane trolley control device for building construction based on UWB technology, such as Figures 1-5As shown, the system includes a connecting platform 1, a support frame 4, and a tower crane trolley 5. The support frame 4 is connected to the upper right end of the connecting platform 1. The lower part of the support frame 4 consists of two symmetrical steel rails, and the upper part is a square steel pipe. The lower and upper parts of the support frame 4 are connected by the steel pipe. The tower crane trolley 5 is slidably connected to the support frame 4. The tower crane trolley 5 includes a moving frame 501, wheels 502, retractable wheels 503, a connecting frame 514, a connecting plate 524, a clamping block 534, and a positioning label 7. Wheels 502 are symmetrically arranged on both the front and rear sides of the upper part of the moving frame 501, and both wheels 502 contact the support frame 4. The wheels 502 on both the front and rear sides contact the top surface of the steel rails on the support frame 4. Retractable wheels 503 are rotatably connected to the middle left and right sides of the moving frame 501. A positioning label 7 is located at the front end of the moving frame 501 near the retractable wheels 503. (UWB is established at the construction site.) The base station and positioning tag 7 work together with the UWB base station to accurately obtain the position of the tower crane trolley 5. The mobile frame 501 has connecting frames 514 on both the front and rear sides. Connecting plates 524 are slidably connected inside the connecting frames 514. The upper part of the connecting plates 524 is close to the support frame 4. The side of the two connecting frames 514 that are close to each other is slidably connected to the clamping blocks 534. The connecting plates 524 and the clamping blocks 534 are in contact with each other. The upper part of the connecting plate 524 is a rectangular plate and the lower part is an inclined plate. The end of the inclined plate that contacts the clamping block 534 is an inclined surface. The middle of the end of the clamping block 534 that is close to the connecting frame 514 has a groove that matches the inclined surface on the inclined plate. When the connecting frame 514 moves the clamping block 534 downward, the inclined plate on the connecting plate 524 squeezes the clamping block 534, so that the clamping block 534 is close to and close to the rail. In this way, the tower crane trolley 5 will not be able to move and will be fixed here.
[0022] like Figure 1 As shown, it also includes a winding machine device 8 and a pulley block 401. Pulley blocks 401 are symmetrically arranged on both the left and right sides of the support frame 4. The winding machine device 8 includes a bracket 801, a drum 803, a rotary motor 802, and a steel wire rope 9. The support frame 4 has a bracket 801, and a rotary motor 802 is located at the rear end of the bracket 801. The drum 803 is symmetrically and rotatably connected to the bracket 801. The drum 803 is connected to the output shaft of the rotary motor 802. The outer side of the drum 803 is wound with the steel wire rope 9. The rotary motor 802 can drive... The drive drum 803 rotates to wind up and unwind the wire rope 9. The wire rope 9 passes through the pulley block 401 on one side of the support frame 4 and comes to the lower part of the support frame 4, where it slides into the take-up and unwinding wheel 503 and finally returns to the drive drum 803. The pulley block 401 facilitates the sliding of the wire rope 9 on the support frame 4. The winding machine 8 realizes the wind up and unwinding of the wire rope 9. The wire rope 9 pulls the take-up and unwinding wheel 503, which in turn drives the wheel 502 to move on the rail of the support frame 4, so that the tower crane trolley 5 can move left and right on the support frame 4.
[0023] like Figure 1 As shown, it also includes a controller 2, a drive motor 201, and a gear set 3. The controller 2 is located on the front top of the connecting platform 1, the drive motor 201 is located on the front top of the connecting platform 1, and the gear set 3 is located at the bottom of the connecting platform 1. The output shaft of the drive motor 201 is connected to the gear set 3. The drive motor 201 can drive the gears in the gear set 3 to rotate, so that the whole device rotates. The drive motor 201 and the rotary motor 802 are both wired to the controller 2.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a maintenance frame 505 and an elastic element 554. Maintenance frames 505 are provided on both the front and rear sides of the mobile frame 501. When the tower crane trolley 5 malfunctions, the operator can repair the tower crane trolley 5 through the maintenance frame 505. Elastic elements 554 are connected on both the left and right sides between the connecting frame 514 and the clamping block 534. When the clamping block 534 is squeezed by the connecting plate 524, the elastic element 554 changes from the initial state to the relaxed state. When the clamping block 534 is not squeezed by the connecting plate 524, the elastic element 554 resets and drives the clamping block 534 back to the initial position.
[0025] Before using this device, a UWB base station should be established near the construction site, and the positioning tag 7 (containing a positioning chip) should be debugged. Positioning work badges (containing positioning chips) should be issued to the operators below the tower crane trolley 5. The wire rope 9 is wound and unwound using the winding machine 8. The wire rope 9 pulls the winding wheel 503, which in turn moves the wheel 502 on the rail of the support frame 4, allowing the tower crane trolley 5 to move left and right on the support frame 4. If the wheel 502 on the tower crane trolley 5 detaches, the load-bearing body of the tower crane trolley 5 changes from the wheel 502 to the connecting plate 524. The connecting plate 524 will directly contact the rail of the support frame 4 and bear the weight of the tower crane trolley 5. The clamping block 534 moves downward relative to the connecting plate 524, and the lower inclined surface of the connecting plate 524 slides against the clamping block 534. When the upper side of the groove contacts each other, the connecting plate 524 pushes the clamping block 534 close to the rail of the support frame 4 until the clamping block 534 clamps the rail. At this time, the tower crane trolley 5 will be fixed here and cannot move. This can prevent the tower crane trolley 5 from falling off the support frame 4 and causing a major safety accident. When the operator stands under the tower crane wearing a positioning badge, the distance signal data between the operator and the tower crane trolley 5 can be transmitted to the controller 2 through the UWB base station. The controller 2 first starts the drive motor 201, which drives the gear set 3 to rotate, thereby causing the device to rotate and move closer to the operator. When the support frame 4 is directly above the operator, the drive motor 201 is turned off, and the controller 2 starts the rotating motor 802, causing the tower crane trolley 5 to move and move closer to the operator. When the tower crane trolley 5 is close to the operator, the controller 2 turns off the rotating motor 802.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
