Description

Heavy hammer type drum tension wire pulling device

Technical Field

The utility model relates to engineering machinery, in particular to a heavy hammer type drum tension wire pulling device.

Background Art

In order to reduce vehicle exhaust emissions, more and more construction machinery has been electrified. However, the electrified construction machinery must carry a huge battery pack, which undoubtedly increases the cost of electrification. At present, the working range of many construction machinery is very limited, and the use of battery packs is not so cost-effective. Therefore, the method of connecting wires to construction machinery by special power supply towers has begun to be put into use. However, the current power supply tower is relatively simple, and the cable is suspended by a steel wire rope, and the steel wire rope is controlled by a counterweight to retract. The working radius itself is relatively narrow, and after working for a period of time, the cable on the top of the power supply tower is very easy to break after bending back and forth, causing the construction machinery to stop. At the same time, the existing power supply tower is mainly limited by the counterweight. If the construction machinery driver is not careful, it is possible to break the power supply line, causing the equipment to stop for maintenance. The existing counterweight also has the problem of no fixed structure. During the up and down movement, it is very likely to shake and eventually collide with the bracket, causing it to be damaged.

At present, the invention with patent number CN102277888A discloses a power-supply electric excavator device, which provides continuous power to the vehicle-mounted motor through the vehicle-mounted electric pole, and the motor replaces the fuel engine to provide power for the vehicle body. It is composed of a basic vehicle body unit, a vehicle-mounted electric pole unit, a vehicle-mounted motor unit and a power supply unit. The basic vehicle body unit is an excavator vehicle body without a fuel engine system. The vehicle-mounted electric pole unit is arranged on a revolving platform, and it is composed of a hollow base, a lower support rod, a spring assembly, an upper support rod, a fixed pulley, and a small winch. The vehicle-mounted motor unit replaces the fuel engine with an electric motor, and replaces the power of the fuel engine with the power of the electric motor to provide energy for the vehicle body, including an electric motor, a special distribution box and a cable. The power supply unit is a municipal power supply connected to the construction site, including a cement electric pole, a common distribution box, a municipal power line, a steel wire rope, a cable eye and a power transmission cable. However, this patent mainly controls the length of the steel wire rope between the power supply tower and the construction machinery through the winch on the construction machinery. The power transmission cable suspended by the lifting ring itself will form multiple wavy large-angle bends. During the operation of the construction machinery, these bends of the power supply cable will continuously stretch and contract, causing the insulation surface of the power supply cable to age and crack rapidly, affecting its service life. At the same time, the excessively high support pole also limits its usage scenarios and its own stability. It can only work in indoor or outdoor places with high ceilings. If the ground is slightly uneven, the support pole may shake, causing the power transmission cable to shake drastically, affecting the normal retraction and release of the power transmission cable.

DETAILED DESCRIPTION

The following describes the weight type drum tension wire pulling device of the utility model embodiment with reference to the accompanying drawings.

In a specific embodiment 1 of the present application, as shown in Figures 1 to 3, the heavy hammer type reel tension wire pulling device (hereinafter referred to as "this patent") includes a counterweight 6, a wire guide 7, a wire collection plate 8, a movable pulley 9 and a limit alarm device 10. The cable reel 2 is installed on the upper part of the reel support plate 5 through the reel rotating bracket 4. The reel support plate 5 can be installed on the top of the power supply tower through the bracket to facilitate the operation of the counterweight 6 while providing a stable working environment for the cable reel 2. The wire collection plate 8 and the power collection wire organizer 11 are fixedly installed on the top of the reel rotating bracket 4. The cable reel 2 is fixedly installed with a wire feeding frame 1 and a wire guide 7 through brackets at the front and back. The wire feeding frame 1 can prevent the cable from hitting the cable reel. 2, one end of the rotating shaft of the cable drum 2 is connected to the counterweight 6 through the winch and the movable pulley 9, and the counterweight 6 controls the winch through the wire rope and the movable pulley 9. Under the action of the counterweight 6, the winch keeps the cable drum 2 in tension, so that the cable connected to the engineering machinery can be output through the wire guide 7 in time and can be retracted into the cable drum 2 in time. The other end passes through the collector ring 3 to connect to the limit alarm device 10; the limit alarm device 10 also includes a magnetic disk 10-1, a switch disk 10-2 and a reducer 10-3, the switch disk 10-2 is fixedly installed on the outside of the drum rotating bracket 4, and the rotating shaft of the magnetic disk 10-1 passes through the center of the switch disk 10-2 and is connected to the rotating shaft of the cable drum 2 through the reducer 10-3. The switch disk 10-2 is fixed. When the cable reel 2 rotates, the magnetic disk 10-1 will also rotate a certain angle. When the magnetic switch on the magnetic disk 10-1 rotates to the magnet at the position corresponding to the switch disk 10-2, the magnetic switch on the magnetic disk 10-1 will send a corresponding switch signal to realize the alarm or on-off of the corresponding position. The reducer 10-3 can reduce the rotation transmitted by the rotating shaft of the cable reel 2 through multi-stage gears, so as to achieve a state in which the magnetic disk 10-1 rotates one tenth of a circle when the cable reel 2 rotates one circle.

A power supply type electric excavator device with invention number CN102277888A (hereinafter referred to as "this patent") mainly controls the length of the steel wire pull line between the power supply tower and the engineering machinery through the winch on the engineering machinery. The power transmission cable suspended by the lifting ring itself will form multiple wavy large-angle bends. In the engineering of the engineering machinery, these bends of the power supply cable will continuously stretch and shrink, causing the insulation surface of the power supply cable to age and crack rapidly, affecting the service life. At the same time, the too high support rod also limits its use scene and its own stability. It can only work in indoor or outdoor places with high ceilings. If the ground is slightly uneven, the support rod may shake, causing the power transmission cable to shake greatly, affecting the normal retraction and release of the power transmission cable. The patent uses a cable reel 2 to make the cable bend more gentle, effectively ensuring the service life of the cable. At the same time, with the help of the limit alarm device 10, the driver can timely understand the retraction and release of the power cable on the cable reel 2, and brake in time to prevent the power supply cable from being torn.

The second embodiment is based on the first embodiment, and the other structures are the same, and the only difference is that, as shown in FIG4 , the lower part of the reel support plate 5 is provided with a vertical rotating frame 12 and a horizontal rotating frame 13 for limiting the moving direction of the counterweight 6, two vertical rotating frames 12 are installed at the diagonal of the counterweight 6, and limiting rings or limiting frames are provided at both ends of the horizontal rotating frame 13. The limiting rings or limiting frames at both ends of the horizontal rotating frame 13 respectively cover a vertical rotating frame 12, and the vertical rotating frame 12 and the horizontal rotating frame 13 respectively provide vertical stability and horizontal stability to the counterweight 6, so that the counterweight 6 can be stably lifted and lowered under the reel support plate 5. It effectively prevents the counterweight 6 from shaking during the up and down movement and hitting the bracket.

In order to further optimize the working efficiency of the present application, the switch disk 10-2 is respectively installed with three magnets at intervals of seventy-five degrees and ninety degrees, and the magnetic disk 10-1 is installed with a magnetic switch at the position where the magnets are installed on the switch disk 10-2. Through the position of the magnets at different intervals, the magnetic switch can issue different alarms at different positions, so that the driver can understand the approximate remaining length of the cable. In order to make the power supply cable more retractable and more stable and provide effective protection for it, the wire guide 7 is composed of a total of four wire rollers up and down, left and right, where the wire rollers on both sides are fifteen to twenty centimeters apart, and the four wire rollers are equipped with rubber sleeves. In order to make the power supply line layout more stable and prevent the cable reel 2 from damaging the line when working, the power supply line connected to the wire feeding frame 1 is overlapped to the collection board 8, and the line of the collection board 8 is connected to the collector ring 3 through the wiring groove reserved on the outside of the reel rotating bracket 4, and the collector ring 3 is electrically connected to the cable laid on the cable reel 2.

When in use, install the heavy hammer drum tension wire pulling device, then install it on the corresponding power supply tower, and connect the corresponding pipelines, and the equipment can be put into operation.

When the utility model is in use, the specific operations are as follows:

When in use, the engineering machinery works within the range allowed by the length of the power supply cable on the cable drum 2 with this patent as the origin. When the engineering machinery moves outward, it drags the cable drum 2, and the power supply cable on the cable drum 2 extends outward through the wire guide 7, and the counterweight 6 rises upward. The counterweight 6 keeps the tension of the cable drum 2 under the action of the movable pulley 9 and the winch. When the engineering machinery moves to the inner circle, the counterweight 6 rotates the cable drum 2 under the action of the movable pulley 9 and the winch to retract the power supply cable. The drum rotating bracket 4 can rotate under the action of the engineering machinery, so that the wire guide 7 can better connect the power supply cable to the engineering machinery.

To prevent the cable from being broken, when the cable reel 2 rotates, the magnetic disk 10-1 will also rotate a certain angle. When the magnetic switch on the magnetic disk 10-1 rotates to the magnet at the position corresponding to the switch disk 10-2, the magnetic switch on the magnetic disk 10-1 will send a corresponding switch signal to realize the alarm or on-off of the corresponding position.

In summary, the weight-type drum tension wire pulling device of the embodiment of the utility model reels and releases the power supply cable through the cable drum 2, and the tension of the cable drum 2 is controlled by the counterweight 6, so that the cable between the cable drum 2 and the engineering machinery is always kept in a suspended state, and at the same time, with the help of the limit alarm device 10, the driver can timely understand the retraction and release status of the power supply cable on the cable drum 2, and brake in time to prevent the power supply cable from being torn, and at the same time, with the help of the vertical rotating frame 12 and the horizontal rotating frame 13, the counterweight can be effectively prevented from shaking, so that the engineering machinery can be more stable during operation.

Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application.
