Description

a lifting mechanism

technical field

The utility model relates to a hoisting mechanism, which belongs to the technical field of cranes.

Background technique

When hoisting containers, a hoisting mechanism is usually used. The existing hoisting mechanism has a mobile trolley that can move on the top of the bracket. The hook pulley block and the hook on the hook pulley block often shake violently due to the center of gravity of the container when hoisting the container. On the other hand, when loading bulk materials into the container, the container needs to be tilted at an angle. The existing The lifting mechanism usually supports one end of the container by the bottom surface, and the other end is lifted by the lifting mechanism. Since one end is first supported by the bottom surface, when the angle changes, the position of the lifted end changes, and the container changes from one angle to the other. At an angle, the feed port changes, but the position of the material is relatively fixed, and people have to follow the feed port to change the position.

The reel of the existing lifting mechanism is driven by a motor, and a brake is set between the motor transmission shaft and the reel. Since there is only one brake, the braking effect is not very good. If the lifting mechanism does not brake in time, it may be damaged. A threat to the safety of on-site staff.

Contents of the invention

The purpose of the utility model is to provide a hoisting mechanism, which solves the technical defect that the angle of the container is not easy to adjust when the container is hoisted in the prior art.

For solving the problems referred to above, the technical scheme that the utility model takes is:

A lifting mechanism comprising

Bracket; The bracket is used to support the remaining components of the lifting mechanism.

The fixed trolley fixed on the top of the bracket, the fixed trolley includes the fixed trolley frame fixed on the top of the bracket, the first motor and the first reducer arranged on the fixed trolley frame, the first brake and the two ends rotating on the fixed trolley The first reel on the frame, the transmission shaft of the first motor is connected to the input shaft of the first reducer through the first brake, the output shaft of the first reducer is connected to the rotating shaft of the first reel, and the first A reel is connected to the first hook pulley block through a wire rope, and the first hook pulley block is provided with a first hook; the first motor rotates, and after being decelerated by the first reducer, the first reel is driven to rotate, and the container under the trolley is hoisted and fixed. .

The mobile trolley is arranged on the top of the support and moves horizontally on the top of the support. The mobile trolley includes a mobile trolley frame forming a moving pair with the top of the support, a second motor, a second reducer, and a second brake arranged on the mobile trolley frame and the two ends rotate the second reel arranged on the frame of the mobile trolley, the transmission shaft of the second motor is connected to the input shaft of the second reducer through the second brake, and the output shaft of the second reducer is connected to the second reel The rotating shaft, the second reel is connected to the second hook pulley block through a wire rope, and the second hook pulley is set on the second hook pulley block; the second motor rotates and drives the second reel after being decelerated by the second reducer Turn and hoist the container under the moving trolley.

The third motor for driving the mobile trolley to move on the top of the support; the third motor drives the mobile trolley to move on the top of the support, so that the container hoisted by the mobile trolley moves in the moving direction of the mobile trolley.

The utility model lifts one end of the container feeding port by the fixed trolley, and lifts the other end of the container by the mobile trolley, since both ends of the container are lifted off the ground, and the position of the fixed trolley between them is fixed. It does not move, so the position of the feed port of the container is relatively fixed, and the moving trolley moves the container up and down, which can change the tilt angle of the container. When the moving trolley lifts the container up and down, it drives the container to move in the horizontal direction, and the container is lifted by the moving trolley. One end of the container moves vertically and horizontally at the same time, while changing the inclination angle of the container, while keeping the position of the container feeding port unchanged, so that the loading personnel can fill the container only by loading at one place, thus improving the The efficiency of loading saves time and manpower.

As a further improvement of the present utility model, both ends of the input shaft of the second reducer protrude from the housing of the second reducer, and the end of the input shaft of the second reducer away from the second motor is provided with a third brake, so The third brake described above is installed on the mobile trolley frame. Set two brakes, the braking effect is better, the braking time is shorter, and when one brake fails, the other brake can still achieve braking, whether it is to shorten the braking time or ensure that at least one brake can work effectively , are beneficial to the safety of the operator.

As a further improvement of the present utility model, two parallel guide rails are arranged horizontally on the top of the support, rollers are arranged on the bottom of the frame of the mobile trolley, and the third motor drives the rollers to slide on the guide rails. The rollers cooperate with the guide rails to make the mobile trolley move on the top of the support, and the rolling friction is small, so the energy consumption of the mobile trolley is less.

As a further improvement of the utility model, a boarding platform is provided at one end of the support, and the boarding platform includes a frame, more than one platform arranged on the frame and a gangway connecting two adjacent platforms. When the container is loaded, one end of the feed port is lifted off the ground, so a boarding platform is set up so that the loading staff can load the container on the platform. Selecting the appropriate platform height and setting up the gangway can not only facilitate the loading personnel to go up and down the platform, but also the maintenance personnel can reach the top of the boarding platform through the gangway, and then climb to the top of the bracket to maintain the fixed trolley and the mobile trolley.

To sum up, the beneficial effect of the utility model is that two trolleys are set up to lift the two ends of the container respectively, so that both ends of the container are lifted when loading, and the position of the feeding port can be maintained when the inclination angle of the container changes. Relatively unchanged, so that the container can be loaded in one place. In the utility model, two brakes are arranged on the mobile trolley, which has good braking effect and good safety performance, and is convenient for maintenance personnel to check up and down.
