Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 Figure 2 , Figure 3This utility model provides a tower crane capable of observing the surrounding environment, including a base frame 1; the base frame 1 is fixedly connected to the tower body 11; a lifting arm 12 is fixedly connected to the top of the tower body 11; a counterweight arm 13 is fixedly connected to the end of the lifting arm 12; a lifting mechanism 14 is fixedly connected to the end of the lifting arm 12; a positioning block 15 is fixedly connected to the side wall of the lifting mechanism 14; a first electric push rod 16 is provided on the inner side wall of the positioning block 15; a connecting block 17 is fixedly connected to the output end of the first electric push rod 16; a motor 18 is fixedly connected to the inner side wall of the connecting block 17; a rotating rod block 19 is rotatably connected to the output end of the motor 18; a monitor 101 is provided on the side wall of the rotating rod block 19; during operation, by activating the first electric push rod 16 to perform lifting and lowering movements, the connecting block 17 can be driven to perform lifting and lowering movements, connecting... When block 17 moves up and down, it drives motor 18 to move up and down, and allows monitor 101 to be in a suitable detection position. By adjusting the height of monitor 101, the detection height it operates at can be adjusted to improve adaptability. Then, motor 18 is started to drive rotating rod block 19 to rotate, thereby adjusting the detection angle of monitor 101. By rotating monitor 101, the effective range of monitor 101 is increased. This design, through the set detection device, can detect the surrounding environment in real time when the hook is operating, so that the staff can understand the lifting situation of the hook in a timely manner. By clearly observing the surrounding buildings, other construction equipment, overhead cables and other obstacles, the running trajectory of the hook can be adjusted in time to prevent collisions and protect the safety of equipment and buildings.

[0026] Furthermore, such as Figure 2 , Figure 3 As shown, a fixing block 2 is fixedly connected to the side wall of the positioning block 15; a second electric push rod 21 is fixedly connected to the inner side wall of the fixing block 2; a placement block 22 is fixedly connected to the output end of the second electric push rod 21; a third electric push rod 23 is fixedly connected to the inner side wall of the placement block 22; an insertion rod 24 is provided at the output end of the third electric push rod 23; multiple sets of positioning slots 25 are opened on the side wall of the first electric push rod 16; the positioning slots 25 are arranged in a linear array; during operation, the second electric push rod 21 is activated to drive the placement block 22 to move up and down, and at the same time, the insertion rod 24 is moved to a suitable position and corresponds to the positioning slot 25. Then, the third electric push rod 23 is activated to drive the insertion rod 24 to be inserted into the positioning slot 25. At this time, the current lifting height of the first electric push rod 16 can be fixed by the insertion rod 24, thereby improving the stability of the first electric push rod 16 at this time. This design uses the insertion rod to fix the first electric push rod, and improves the adjustability of the fixation by using multiple sets of positioning slots and the lifting mechanism of the insertion rod.

[0027] Furthermore, such as Figure 1 , Figure 5As shown, a control room 3 is fixedly connected to the side wall of the tower body 11; a positioning rod block 31 is fixedly connected to the inner side wall of the control room 3; a rotating ball rod 32 is rotatably connected to the inner side wall of the positioning rod block 31; a telescope 33 is fixedly connected to the inner side wall of the rotating ball rod 32; and a handle 34 is fixedly connected to the side wall of the rotating ball rod 32. During operation, when staff need to observe distant objects, they can rotate the rotating ball rod 32 by manipulating the handle 34, thereby adjusting the position of the telescope 33 to a suitable position and pointing the telescope 33's observation port towards the target location. This allows staff to conveniently use the telescope 33 for distant observation and facilitates its retrieval. This design, through the flexible and adjustable telescope, provides staff in the control room 3 with a tool for long-distance observation and also facilitates the retrieval of the telescope 33, improving ease of use.

[0028] Furthermore, such as Figure 4 As shown, a fixed groove block 4 is fixedly connected to the side wall of the hoisting mechanism 14; a rotating disk 41 is rotatably connected to the inner side wall of the fixed groove block 4; a sound wave detector 42 is provided on the side wall of the rotating disk 41; during operation, when the tower crane is working, the sound wave detector 42 can detect sound waves in the working range of the hook. When an external object is encountered around the hook, the movement of the external object will emit sound waves. When the sound wave detector 42 is impacted by the sound waves, it will send a signal through the transmitter to remind the staff in the control room, thereby increasing the staff's awareness and facilitating timely adjustments and avoidance. This design, through the sound wave detection device, can detect and warn of sound wave movement in the working range of the hook, and promptly remind the staff so that they can make timely adjustments and avoidance operations, thereby improving safety.

[0029] Furthermore, such as Figure 4 As shown, the fixed slot 4 has a slot 5 on its side wall; the fixed slot 4 has a closed box 51 on its inner side wall; the fixed slot 4 and the closed box 51 are slidably connected; the closed box 51 is detachably connected to the side wall of the slot 5; during operation, when the tower crane is not needed, the closed box 51 can be inserted into the slot 5 to cover and close the acoustic detector 42, reducing the possibility of the acoustic detector 42 being triggered by unexpected acoustic signals. This design reduces the acoustic detector 42 being subjected to unexpected acoustic signals by enclosing and protecting it.

[0030] Furthermore, such as Figure 3 As shown, a rubber sleeve 6 is provided on the side wall of the positioning groove 25. During operation, when the insertion rod 24 is inserted into the positioning groove 25, the rubber sleeve 6 enhances the friction between the insertion rod 24 and the insertion rod 24, thereby improving the stability of the insertion rod 24 when it is inserted into the positioning groove 25. This design improves the stability of the insertion rod to the first electric push rod by enhancing the friction between the insertion rod and the insertion rod.

[0031] Working Principle: Activating the first electric push rod 16 causes it to move up and down, which in turn drives the connecting block 17 to move up and down. This movement of the connecting block 17, in turn, drives the motor 18 to move up and down, positioning the monitor 101 in a suitable detection position. Adjusting the height of the monitor 101 allows for adjustment of its detection height, improving adaptability. Subsequently, activating the motor 18 drives the rotating rod block 19 to rotate, adjusting the detection angle of the monitor 101. This rotation enhances the monitor 101's effective range. Activating the second electric push rod 21 causes the placement block 22 to move up and down, simultaneously positioning the insertion rod 24 in a suitable position, aligning it with the positioning slot 25. Then, activating the third electric push rod 23 inserts the insertion rod 24 into the positioning slot 25. The insertion rod 24 then fixes the current height of the first electric push rod 16, improving its stability. When personnel need to observe distant objects, they can control the movement... The handle 34 drives the rotating rod 32 to rotate, thereby adjusting the position of the telescope 33 to a suitable position and pointing the observation port of the telescope 33 towards the target position. This allows the staff to conveniently use the telescope 33 to observe distant objects and also facilitates the retrieval of the telescope 33. During the operation of the tower crane, the sound wave detector 42 can detect sound waves in the working range of the hook. When the hook encounters an external object, the movement of the external object will emit sound waves. When the sound wave detector 42 is impacted by the sound wave, it will send a signal through the transmitter to alert the staff in the control room, increasing the staff's awareness and facilitating timely adjustments and avoidance. When the tower crane is not in use, the enclosed box 51 can be inserted into the slot 5 to cover and close the sound wave detector 42, reducing the possibility of the sound wave detector 42 triggering an alarm due to unexpected sound wave signals. When the insertion rod 24 is inserted into the positioning slot 25, the rubber sleeve 6 enhances the friction between the insertion rod 24 and the positioning slot 25, improving the stability of the insertion rod 24 when inserted into the positioning slot 25.
