[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] like Figures 1 to 5 As shown, the tank shooting range gun target lifting device provided by the embodiment of the utility model includes a column 1, a connecting bracket 2, a left support member 3, a first travel switch 4, a travel switch frame 5, a base 6, a support 7, a lifting frame assembly 8, a wire rope 9, a right support member 10, a pulley 11, a rain cover welding 12, a second travel switch 13, a crank 14, a power device assembly 15, a connecting plate 16, a first flat key 17, a transmission shaft 18, a second flat key 19, a coupling sleeve 20, a drum welding 21, a drum shaft 22, a bearing sleeve 23, a self-aligning ball bearing 24, a third flat key 25, a left bracket 26, a right bracket 27, a wire rope clamp 28, a bracket plate 29, a connecting block 30, a transition sleeve 31, a fixed target control box 32, and a handle latch 33.

[0034] There are two columns 1, and the left and right columns 1 are arranged in parallel and connected by four connecting brackets 2, and the four connecting brackets 2 are distributed at intervals. The left support member 3 and the right support member 10 are respectively connected to the left and right columns 1, and the extended surface is connected to the bunker wall to form a stable support for the left and right columns 1.

[0035] The first travel switch 4 and the second travel switch 13 are respectively fixedly connected to the travel switch frame 5, and the travel switch frame 5 is connected to the column 1. The first travel switch 4 is located at the lower part of the column 1, and the second travel switch 13 is located at the upper part of the column 1.

[0036] The bottom of the column 1 is fixed on the base 6, and the left and right columns 1 are respectively connected and reinforced with the base 6 by a plurality of supports 7. Two pulleys 11 are respectively installed on the top of the left and right columns 1, and a rain cover welding 12 is installed above the pulley 11, which can prevent rainwater from entering the pulley 11 and affecting its normal use.

[0037] The power device assembly 15 is fixedly connected to the coupling plate 16. The power device assembly 15, the coupling plate 16, and one end of the transmission shaft 18 are all provided with keyways and are tightly matched through the first flat key 17. The other end of the transmission shaft 18 and the coupling sleeve 20 are both provided with keyways and are tightly matched through the second flat key 19. The coupling sleeve 20 is connected to the drum welding 21 on one side by bolts. The drum shaft 22 passes through the left and right drum weldings 21, and the left and right drum weldings 21 are located on the inner sides of the left and right columns 1. The drum shaft 22 and the left and right drum weldings 21 are both provided with keyways and are tightly matched through the third flat key 25. Two self-aligning ball bearings 24 are respectively installed in two bearing sleeves 23, and the bearing sleeves 23 are respectively installed on the left bracket 26 and the right bracket 27. The left bracket 26 and the right bracket 27 are respectively connected to the left and right columns 1. The two self-aligning ball bearings 24 and the bearing sleeve 23 are located on the inner side of the two reel welds 21, which can effectively ensure the smoothness of the reel shaft 22 during rotation and provide stable support for it.

[0038] In this embodiment, the power device assembly 15 is prior art, and thus will not be described in detail here.

[0039] One end of the wire rope 9 is wound around the drum welding 21 and passes through the slot of the wire rope pulley assembly 11, and the other end is connected to the lifting frame assembly 8 through the wire rope clamp 28. The lifting frame assembly 8 is driven to rise, fall, and stop by the traction of the wire rope 9. When the lifting frame assembly 8 falls, it finally stops on the bracket plate 29.

[0040] The power device assembly 15 is connected to the transition sleeve 31, and the transition sleeve 31 is tightly connected to the connecting block 30. The crank 14 is provided with a handle pin 33, and the connecting block 30 is provided with a long slot. When the crank 14 is inserted into the connecting block 30, the handle pin 33 of the crank 14 cooperates with the long slot of the connecting block 30 to clamp the crank 14. By shaking the crank 14, the connecting block 30 and the transition sleeve 31 are driven to rotate, thereby driving the motor in the power device assembly 15 to rotate with the crank, and then driving the entire lifting device to move up and down.

[0041] The fixed target control box 32 includes a power switch, an operation button, and an indicator light, among which the power switch is used to connect or disconnect the working power of the system, the indicator light is used to display the status of the system power supply and control, and the operation button is used to send control instructions to the system to control the rotation direction of the motor, thereby driving the lifting frame assembly 8 to rise, stop, and descend. The control of the rotation direction of the motor can be achieved using conventional technical solutions in the field, so this embodiment will not be described in detail here.

[0042] During use, when the "target display" operation needs to be controlled, the power switch on the fixed target control box 32 needs to be started and the "target display" button needs to be pressed, and the motor in the power device assembly 15 starts to work and rotate. The power device assembly 15 and the connecting plate 16 and one end of the transmission shaft 18 are provided with a keyway to form a tight fit through the first flat key 17; the coupling sleeve 20 and the other end of the transmission shaft 18 are provided with a keyway to form a tight fit through the second flat key 19; the coupling sleeve 20 is connected to the reel welding 21 on one side; the reel shaft 22 and the reel welding 21 on the left and right sides are provided with the same keyway to form a tight fit through the third flat keys 25 on the left and right sides, and through the groove The key-matching method ensures the "integration" of the moving drum shaft 22 and the drum weldings 21 on both sides; when the power device assembly 15 rotates through the above cooperation, the transmission shaft 18, the drum shaft 22 and the drum weldings 21 on the left and right sides are driven to rotate simultaneously; then one end of the wire rope 9 is driven to gradually wind around the drum welding 21, thereby driving the lifting frame assembly 8 fixed to the other end of the wire rope 9 to rise along the guide rail of the column 1. When the lifting frame assembly 8 contacts the second travel switch 13 at the upper end, the second travel switch 13 triggers the motor self-locking in the power device assembly 15, and the device automatically stops in place, so that the lifting frame assembly 8 is fixed, as shown in FIG. Figure 1 The dotted line position in .

[0043] On the contrary, when the "hide target" button is pressed, the motor in the power device assembly 15 reverses, thereby driving the lifting frame assembly 8 to descend along the guide rail of the column 1 through the above structure. When the lower end of the lifting frame assembly 8 contacts the first travel switch 4, the first travel switch 4 triggers the motor in the power device assembly 15 to self-lock, thereby achieving automatic stop of the device in place.

[0044] If the "stop" button of the fixed target control box 32 is pressed during operation, the fixed target control box 32 stops supplying power, and the power device assembly 15 stops rotating after losing power.

[0045] If the target is lifted manually, the crank 14 is inserted into the connecting block 30. The connecting block 30 is designed with a long slot hole, which cooperates with the handle pin 33 of the crank 14. By shaking the crank 14, the connecting block 30 and the transition sleeve 31 are driven to rotate, thereby driving the motor to rotate with the crank 14, and continue to drive the transmission shaft 18, the coupling sleeve 20, the drum welding 21, the drum shaft 22 and other components to rotate at the same time. As the rotation direction changes, the wire rope 9 is wound around or released from the drum welding 21.

[0046] After the training is finished, the motor in the power device assembly 15 is driven to rotate by the crank 14, driving the lifting frame assembly 8 to fall down and fall onto the bracket plate 29, so that the lifting frame assembly 8 is fixed on the bracket plate 29. Figure 1 The bracket plate 29 plays a role in supporting the lifting frame assembly 8, and the wire rope 9 is basically not subjected to force, thereby extending the service life of the wire rope 9.

[0047] In the above description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the above examples are merely preferred implementation methods of the present invention and cannot be used to limit the scope of rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
