Description

Container loading and unloading device with inching start and stop function

Technical Field

The utility model belongs to the container field of lifting by crane, concretely relates to container loading and unloading device with inching opens and stops function.

Background

At present, a container lock head is installed on a floor of a railway freight car to ensure that a container and the railway freight car are not separated and overturned in the railway transportation process. According to the operation regulation, when a container loaded by a railway freight car is loaded and unloaded, a special container lifting appliance needs to be temporarily braked when the container is inching and lifted at a low speed for 100mm, and the lifting operation can be continuously carried out after the container is smoothly separated from the railway freight car. However, the existing device can not accurately realize the aim of automatically stopping the hoisting operation, and each hoisting operation needs manual operation to carry out emergency braking when the hoisting operation is performed at a low speed and inching for 100 mm. Because the manual operation accuracy is lower, in the actual hoisting process, the damage of the corner fitting hole of the container, the damage of the lock head of the railway freight car or the derailment accident of the railway freight car is easily caused. The prior container loading and unloading mechanical devices in the market can not effectively solve the problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a container loading and unloading device with point is moved and is stopped function opens, control that can be accurate lifts by crane the height, solves the problem that container corner fittings hole and railway freight car tapered end are even hung, the card is dead or damage the vehicle.

The utility model provides a following technical scheme:

the utility model provides a container loading and unloading device with point is moved and is stopped function, is including being used for lifting by crane the hoist to the container, be equipped with on the hoist and constitute locking complex tapered end with container upper portion corner fittings hole, be equipped with the range finding sensor who detects distance between hoist and the freight train floor on the tapered end, loading and unloading device still includes motor and controller, the motor is connected with hoist, controller electricity respectively, the controller is connected with the range finding sensor electricity.

Preferably, the tapered end is equipped with four, distributes in the four corners of hoist, all is equipped with a range sensor on every tapered end.

The utility model has the advantages that:

compared with the prior art, the device can not accurately stop the hoisting operation, and needs manual operation to perform emergency braking when the hoisting is performed at a low speed and the hoisting is performed for 100mm each time.

The utility model discloses in the operation process of lifting by crane the container, when arbitrary distance measuring sensor lifts by crane range finding numerical value (the distance on range finding sensor and railway freight car floor) subtract initial value (the initial value is for the distance on range finding sensor and railway freight car floor when the hoist tapered end stretches into container upper portion corner fittings hole and locking) and reach 100mm, lead to this distance measuring sensor to be aroused, with signal transmission to controller, stop lifting by crane the operation by controller control motor, the hoist stops the motion of lifting by crane temporarily, with container lower part corner fittings hole and railway freight car vehicle tapered end complete segregation, ensure that the container smoothly separates with railway freight car vehicle when lifting by crane 100 mm. When the subtraction (initial value) of the distance measurement values of all the distance measurement sensors exceeds 100mm, the controller is not restrained to continue lifting.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The designations in the drawings have the following meanings:

1-container 2-sling 3-lock 4-truck floor 5-distance measuring sensor 6-motor 7-controller

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

Example 1

As shown in fig. 1, a container handling device with inching start-stop function, including the hoist 2 that is used for lifting by crane container 1, be equipped with on the hoist 2 with container 1 upper portion corner fittings hole constitution locking complex tapered end 3, be equipped with the range sensor 5 that detects the distance between hoist 2 and the freight train floor 4 on the tapered end 3, handling device still includes motor 6 and controller 7, motor 6 is connected with hoist 2, controller 7 electricity respectively, controller 7 is connected with range sensor 5 electricity.

Example 2

On the basis of the embodiment 1, four lock heads 3 are arranged and distributed at four corners of the lifting appliance 2, and each lock head 3 is provided with a distance measuring sensor 5;

the controller 7 is wirelessly connected with the ranging sensor 5.

The working process of the utility model is as follows:

in the process of lifting the container, when the lifting distance measurement value (the distance between the distance measurement sensor and the floor of the railway freight car) of any distance measurement sensor subtracts an initial value (the initial value is the distance between the distance measurement sensor and the floor of the railway freight car when a lock head of a lifting appliance extends into an upper corner fitting hole of the container and is locked), the distance measurement sensor is excited, a signal is transmitted to a controller, the motor is controlled by the controller to stop lifting operation, the lifting appliance stops lifting movement temporarily, the lower corner fitting hole of the container is completely separated from the lock head of the railway freight car, and the container is ensured to be smoothly separated from the railway freight car when the container is lifted by 100 mm. When the subtraction (initial value) of the distance measurement values of all the distance measurement sensors exceeds 100mm, the controller is not restrained to continue lifting.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
