Description

Electric Lifting Rescue Triangle Bracket

technical field

The utility model relates to an electric lifting rescue triangular support.

Background technique

The current tripods on the market use manual reels. When in use, first fix the tripod, and lift objects or personnel with the hook. Then another person rotates the reel so that the wire rope in the reel lifts the rescuer or rescue item up or down through the block of pulleys. During the operation of the manual reel, there are two problems. One, the coordination problem between the operator and the hoisted personnel. Improper coordination can easily lead to accidents. 2. Two people are required for rescue. If there is only one person, the rescue work will not be able to be carried out and is subject to certain restrictions.

Utility model content

The technical problem to be solved by the utility model is to provide an electric lifting rescue triangular bracket that can be lifted and lowered automatically by a reel, can be operated by one person, and has high use efficiency.

The technical scheme adopted by the utility model is: an electric lifting rescue triangular bracket, which includes a mounting seat, a support rod evenly distributed on the mounting seat, a reel arranged on one of the support rods, and a reel for driving the reel. The motor reducer that the disk rotates and the fixed pulley arranged in the middle of the mounting base are connected with an infrared remote control module that is used to control the start and stop of the motor and can be controlled by remote control on the motor reducer.

The pole of the utility model includes an upper pole and a lower pole that are socketed with each other. The upper end of the upper pole is hinged with the mounting seat, and the lower end of the upper pole is socketed with the lower pole. A transmission rod is arranged in the upper support rod and the lower support rod, the upper part of the transmission rod is a worm, the lower part of the transmission rod is a threaded rod, and a bearing is fixedly arranged in the upper support rod. The upper end is in interference fit with the inner ring of the bearing, and a fixed plate is fixedly arranged in the lower support rod, and an internal thread is arranged on the fixed plate, and the threaded rod is adapted to the internal thread on the fixed plate. A worm gear driven by a reduction motor is arranged on the upper support rod, and the worm gear is engaged with the worm.

In the utility model, a ball joint is arranged at the bottom of the lower pole, one end of the ball joint is fixedly connected with the lower pole, and the other end is provided with a support plate.

In the utility model, a lock ring is arranged at both ends of the support plate, and a fixed chain is arranged between the support plates at the lower ends of two adjacent poles, and the two ends of the fixed chain are fixedly connected with the lock ring.

The positive effects of the utility model are: the reel of the utility model is driven by the motor reducer to realize forward and reverse rotation, and at the same time, the motor reducer is provided with an infrared remote control module, which can be remotely controlled by the remote control, and the hoisting personnel only need to control the remote control. The start, stop, rise and fall actions of the motor reducer can be realized, and one person can work with high work efficiency. At the same time, the length of the support rod can be adjusted according to the actual situation at any time, and the application range is wide. The support rod drives the transmission rod to rotate through the worm gear and worm, so that the threaded rod rotates in the fixed plate, and the position of the fixed plate on the threaded rod changes, thereby adjusting the leakage length of the lower support rod and changing the length of the support rod. The self-locking feature of the worm can effectively prevent the length of the strut from retracting by itself during use, and the reliability is high.

detailed description

As shown in accompanying drawings 1 and 2, the utility model includes a mounting base 1, a pole 2 evenly distributed on the mounting base 1, a reel 3 arranged on one of the poles 2, and a reel 3 for driving The rotating motor reducer 4 and the fixed pulley 5 arranged in the middle of the mounting base 1 are connected with an infrared remote control module for controlling the start and stop of the motor and can be controlled by remote control on the motor reducer 4 . One end of the wire rope is wound on the reel 3, and the other end walks around the fixed pulley 5 to lift staff or rescue items. During the working process, the staff only need to hold the remote control, and control the working conditions of the motor reducer 4 through the infrared remote control module, so as to realize start-stop, ascent and descent.

The pole 2 includes an upper pole 201 and a lower pole 202 which are nested in each other. Then, a transmission rod 6 is arranged in the upper support rod 201 and the lower support rod 202, the upper part of the transmission rod 6 is a worm 7, the lower part of the transmission rod 6 is a threaded rod 8, and the upper support rod 201 is fixedly provided with a bearing 9, the upper end of the transmission rod 6 is in interference fit with the inner ring of the bearing 9, a fixed plate 10 is fixedly provided in the lower support rod 202, and an inner ring is provided on the fixed plate 10. screw thread, the threaded rod 8 is adapted to the internal thread on the fixed plate 10, and the worm wheel 11 driven by a reduction motor is arranged on the upper support rod 201, and the worm wheel 11 is engaged with the worm screw 7. On the upper support rod 201, there is a groove for meshing the worm wheel 11 with the worm screw 7. The worm gear 11 is fixedly arranged on the upper support rod 201. After the upper support rod 201 and the lower support rod 202 are socketed, they are connected through the transmission rod 6, and the worm gear 11 rotates under the drive of the deceleration motor, thereby driving the threaded rod 8 at the bottom of the transmission rod 6 to rotate, and the threaded rod 8 is screwed to the fixed plate 10 fixedly arranged in the lower support rod 202, so that the lower support rod 202 can be driven to rise or fall. Down, the length of the support rod 2 can be adjusted according to different usage conditions, especially in the environment where the ground is uneven, several support rods 2 can be adjusted to different lengths, and the adaptability is very high.
