Description

Technical Field

[0001] The utility model relates to the technical field of bridge crane paralleling, and more specifically, to a locking device and a bridge crane paralleling device. Background Art

[0002] In the prior art, when the weight of the hoisted object is greater than the rated lifting capacity of a single bridge crane, two bridge cranes with the same parameters are required to be used in parallel to lift the object at the same time. Currently, there are two main forms of bridge cranes:

[0003] The first is mechanical paralleling, that is, using a mechanical connecting rod to hard-connect the two bridge cranes;

[0004] The second is electrical parallel operation, which uses a communication cable to connect the control systems of the two bridge cranes, with one of the cranes serving as the main vehicle to control both cranes at the same time.

[0005] Most of the current application scenarios use both methods at the same time, that is, first mechanical paralleling is adopted to mechanically connect the two bridge cranes, and then electrical paralleling is carried out, and the main vehicle controls the operation of the two bridge cranes at the same time;

[0006] There are generally two ways to mechanically combine bridge cranes:

[0007] The first is to manually carry the mechanical connection, dock the mechanical connecting rod in place, and tighten it with bolts. This method is inefficient, labor-intensive, and has the risk of falling objects and high-altitude operations;

[0008] The second method is to use electricity, hydraulics and other power forms to dock the mechanical connecting rods in place and tighten the bolts manually. This method reduces labor intensity to a certain extent, but the efficiency is low. When the mechanical connection is docked, the position of the bridge crane needs to be fine-tuned frequently, and the operator is at risk of falling from a height or falling objects from a height.

[0009] The electrical connection of bridge cranes is currently made using communication cables, and the connection operation of communication cables also carries the risk of people falling from heights and objects falling from heights. Utility Model Content

[0013] After the two groups of bridge cranes are moved into place, the locking beam is controlled by the telescopic drive device to rotate around the hinge point between the locking beam and the bridge crane and placed on the other group of bridge cranes. The locking beam is then locked with the bridge crane by the locking mechanism. Thus, the locking of the two groups of bridge cranes after the two groups of bridge cranes are realized. Compared with the existing technology, manual locking is no longer required, which reduces the safety risks that are very likely to occur in manual locking.

[0016] In some possible implementations, in order to effectively drive the locking beam to rotate around the hinge point between the locking beam and the bridge crane, the locking beam cooperates with the locking mechanism to connect and fix the two groups of bridge cranes;

[0017] The telescopic driving device is a driving cylinder; wherein one end of the driving cylinder is hinged to the pier and the other end is hinged to the locking beam.

[0018] In some possible implementations, in order to effectively lock the locking beam and the bridge crane through the locking mechanism;

[0019] The locking mechanism comprises a telescopic oil cylinder installed outside the anchor pier and forming a slot between the anchor pier and a locking pin connected to the piston rod of the telescopic oil cylinder and coaxially arranged;

[0023] A bridge crane paralleling device is used for paralleling and locking two groups of bridge cranes; it includes a distance meter installed on one group of bridge cranes, a distance measuring plate arranged on the other group of bridge cranes and used in conjunction with the distance meter, a locking mechanism for locking the two groups of bridge cranes, and a control module connected with the distance meter and the locking mechanism.

[0024] In some possible implementations,

[0025] It also includes a laser displacement sensor installed on one group of bridge cranes and a positioning scale installed on another group of bridge cranes and used in conjunction with the laser displacement sensor; the laser displacement sensor is connected to the control module.

[0026] In some possible implementations,

[0027] It also includes a monitoring system installed on the two groups of bridge cranes and used to monitor the distance between the two groups of bridge cranes and the parallel vehicle status; the monitoring system is connected to the control module.

For example, multiple positioning columns refer to two or more positioning columns. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0040] The utility model is described in detail below.

[0041] Embodiment 1:

[0042] like Figure 1 A locking device is used for locking two groups of bridge cranes 100 after they are put in parallel; it includes a locking beam 3 with one end hinged to one group of bridge cranes 100, a telescopic driving device 4 with one end hinged to the locking beam 3 and the other end hinged to the bridge crane 100 hinged to the locking beam 3, and a locking mechanism 5 installed on another group of bridge cranes 100 and used for locking the locking beam 3 and the group of bridge cranes 100.

[0043] After the two groups of bridge cranes 100 are moved to their positions, the locking beam 3 is controlled by the telescopic driving device 4 to rotate around the hinge point between the locking beam 3 and the bridge crane 100, and is placed on another group of bridge cranes 100, and then the locking mechanism 5 is used to lock the locking beam 3 and the group of bridge cranes 100; thereby, the locking of the two groups of bridge cranes 100 after being put in parallel is realized, and compared with the prior art, manual locking is no longer required, reducing the safety risks that are very likely to occur due to manual locking;

[0044] Further, the telescopic driving device 4 is located below the locking beam 3;

[0045] In some possible implementations, in order to effectively realize the articulation of the locking beam 3 with one group of bridge cranes 100 and to lock it with another group of bridge cranes 100 through the locking mechanism 5;

[0046] It also includes a pier 1 which is arranged on one group of bridge cranes 100 and is hinged to the locking beam 3, and an anchor pier which is arranged on another group of bridge cranes 100 and is used to install the locking mechanism 5.

[0047] The pier 1 is installed on the top surface of one group of bridge cranes 100, and the anchor pier is installed on the top surface of the other group of bridge cranes 100; one end of the locking beam 3 is hinged to the pier 1, and the two ends of the telescopic drive device 4 are respectively hinged to the pier 1 and the locking beam 3, so as to control the locking beam 3 to rotate around the hinge point between it and the pier 1; so that when the two groups of bridge cranes 100 are parallel, the locking beam 3 will not interfere with the parallel operation; after the parallel operation reaches a specified distance, the telescopic drive device 4 controls the locking beam 3 to rotate around the hinge point between it and the pier 1 and place it on the anchor pier, and then the locking mechanism 5 connects and locks the anchor pier 2 and the locking beam 3; the locking of the two groups of bridge cranes 100 after the parallel operation is completed;

[0048] In some possible implementations, in order to effectively drive the locking beam 3 to rotate around the hinge point between the locking beam 3 and the bridge crane 100, the locking beam 3 cooperates with the locking mechanism 5 to connect and fix the two groups of bridge cranes 100;

[0049] The telescopic driving device 4 is a driving cylinder; wherein one end of the driving cylinder is hinged to the pier 1 and the other end is hinged to the locking beam 3.

[0050] Specifically, the piston rod of the driving cylinder is connected to the locking beam 3, and the other end thereof is connected to the buttress 1;

[0051] Furthermore, the locking beam 3 includes two groups of bodies arranged in parallel and a connecting rod arranged between the bodies; the piston rod of the driving cylinder is connected to one of the groups;

[0052] In some possible implementations, in order to effectively lock the locking beam 3 and the bridge crane 100 through the locking mechanism 5;

[0053] The locking mechanism 5 comprises a telescopic oil cylinder installed outside the anchor pier and forming a slot between the anchor pier and a locking pin 6 connected to the piston rod of the telescopic oil cylinder and coaxially arranged;

[0054] The slot will be used to lock the fixation between the main body and the anchor pier in the beam 3;

[0055] A through hole 1 for the locking pin 6 to pass through is provided on the anchor pier, and a through hole 2 for use in conjunction with the through hole 1 is provided on the locking beam 3;

[0056] Further, through hole 2 is provided on the two groups of bodies and is used in conjunction with through hole 1;

[0057] After the locking beam 3 is placed on the anchor pier, the through hole 1, through hole 2 and the locking pin 6 will be coaxial, and the telescopic cylinder will control the locking pin 6 to pass through the through hole 2, through hole 1 and through hole 2 in sequence; thus, the locking connection between the locking beam 3 and the anchor pier 2 can be achieved;

[0058] In some possible implementations, in order to effectively monitor the positional relationship between the locking beam 3 and the anchor pier and the locking pin 6, so that the locking beam 3 can effectively connect the two groups;

[0059] It also includes a position detection switch 1 7 which is arranged on the anchor pier and is used to monitor the position of the locking beam 3 , and a position detection switch 2 8 which is used to monitor the position of the locking pin 6 .

[0060] The position detection switch 1 7 is used for the telescopic driving device 4 to detect the position of the locking beam 3 when the locking beam 3 is placed on the anchor pier. When the position meets the requirements and the through hole 1 is coaxially connected with the through hole 2, the telescopic driving device 4 stops driving;

[0061] The position detection switch 2 8 is used to determine whether the locking pin 6 passes through the two groups of bodies of the locking beam 3. When the free end of the locking pin 6 passes through the two groups of bodies, the position detection switch 2 8 will be able to detect the position of the free end of the locking pin 6, and at this time the telescopic cylinder will stop controlling the locking pin 6;

[0062] Compared with the locking method in the prior art, the locking device of the present application does not require manual locking and frequent position adjustment, and is simple and convenient to operate; it avoids the possibility of safety accidents during manual operation in the prior art.

[0063] Embodiment 2:

[0064] like Figure 1-Figure 4 As shown, a bridge crane paralleling device is used for paralleling and locking two groups of bridge cranes 100; it includes a distance meter 9 installed on one group of bridge cranes 100, a distance measuring plate 10 arranged on the other group of bridge cranes 100 and used in conjunction with the distance meter 9, a locking mechanism 11 for locking the two groups of bridge cranes 100, and a control module connected to the distance meter 9 and the locking mechanism 11.

[0065] During the process of merging vehicles, the distance meter 9 and the distance measuring board 10 cooperate to measure the distance between the two bridge cranes 100 brackets, so that they can be moved as required. After the distance requirement is reached, the locking mechanism 11 will start to lock the two groups of bridge cranes 100;

[0066] In some possible implementations, in order to make the distance between the two groups of bridge cranes 100 more accurate;

[0067] It also includes a laser displacement sensor 12 installed on one group of bridge cranes 100, and a positioning scale 13 installed on another group of bridge cranes 100 and used in conjunction with the laser displacement sensor 12; the laser displacement sensor 12 is connected to the control module;

[0068] In some possible implementations, in order to facilitate the bridge crane driver to grasp the vehicle merging status in real time and make correct judgments in time;

[0069] It also includes a monitoring system installed on the two bridge cranes 100 and used to monitor the distance between the two bridge cranes 100 and the parallel vehicle status; the monitoring system is connected to the control module;

[0070] During the vehicle merging process, the monitoring system transmits real-time monitoring data to the bridge crane driver through the control module, so that the bridge crane driver can stop the vehicle merging in time in case of an emergency;

[0071] The distance meter 9 and the laser displacement sensor 12 transmit the distance between the two bridge cranes 100 to the control module during the whole process of paralleling, so that the bridge crane driver can connect to the paralleling situation in real time and stop the vehicle after reaching the distance requirement;

[0072] Further, the rangefinder 9 and the laser displacement sensor 12 are arranged on the same side, and are arranged on the side of the same group of bridge cranes 100 close to another group of bridge cranes 100, and the rangefinder plate 10 and the positioning scale 13 are arranged on the side of another group of bridge cranes 100 close to the rangefinder 9 and the laser displacement sensor 12;

[0073] In some possible implementations,

[0074] The locking mechanism 11 is the locking device of embodiment 1;

[0075] The telescopic drive device 4, the locking mechanism 5, the position detection switch 1 7, and the position detection switch 2 8 are respectively connected to the control module;

[0076] The control module will serve as the central system to control the work of each mechanism.

[0077] The above-mentioned method for paralleling bridge crane paralleling devices specifically comprises the following steps:

[0078] The two groups of bridge cranes 100 move toward each other to perform parallel operation. The distance between the bridge cranes 100 is monitored in real time by the rangefinder 9 and the laser displacement sensor 12. After reaching the parallel operation distance, the parallel operation is stopped. During this period, the monitoring system monitors the parallel operation status in real time and transmits the data to the control module.

[0079] Specifically, the rangefinder 9 is mainly used when the distance between the two bridge cranes 100 is far, such as Figure 2 As shown, when the distance between the bridge cranes 100 is greater than D1, distance measurement is performed, and the accuracy requirement for distance measurement is not high at this time;

[0080] Further, the rangefinder 9 is an ultrasonic anti-collision rangefinder 9, and the rangefinder board 10 is an ultrasonic echo board;

[0081] When the two bridge cranes 100 move to the point where the distance measurement can be achieved by using the cooperation of the laser displacement sensor 12 and the positioning scale 13, as shown in FIG. Figure 3 As shown, when the distance between the bridge cranes 100 is D1, the bridge crane driver will control the bridge crane to slow down. At this time, the distance measurement will start with the laser displacement sensor 12 to measure the distance between the bridge cranes 100. The data measured by the laser displacement sensor 12 has higher accuracy.

[0082] When merging, the bridge crane driver controls the two groups of bridge cranes 100 to approach each other to achieve merging;

[0083] During the merging process, rough positioning is achieved through the distance meter 9 and the distance measuring board 10, and high-precision positioning is achieved through the cooperation of the laser displacement sensor 12 and the positioning scale 13, so that the distance control between the two groups of bridge cranes 100 is more accurate;

[0084] During the whole process of merging vehicles, the monitoring system will monitor the whole process and transmit the monitoring data to the control module, which will then transmit the data to the bridge crane driver, so that the driver can understand the merging status in real time and directly stop driving if any abnormality occurs.

[0085] During the process of merging vehicles, the distance meter 9 and the laser displacement sensor 12 will transmit the distance between the future bridge cranes 100 to the control module, and the control module will transmit the data to the bridge crane driver, so that the bridge crane driver can grasp the distance between the two groups of bridge cranes 100 in real time;

[0086] When the requirements are met and the distance between the two bridge cranes 100 is D2, the vehicle can be stopped;

[0087] The telescopic driving device 4 controls the locking beam 3 to rotate around the hinge point between the locking beam 3 and the pier 1 and to be inserted into the anchor pier. The oil cylinder stops moving and the locking mechanism 5 locks the locking beam 3.

[0088] Complete the car merging.

[0089] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
