Description

Technical Field

[0001] The present invention relates to the technical field of rail transit maintenance equipment, and particularly relates to a multi-functional platform vehicle for railway maintenance. Background Art

[0002] The high-frequency use and load-bearing conditions of railway lines are very likely to cause damage to railway lines. If timely maintenance and repair are not carried out, there may very likely be potential safety hazards in the operation of railway lines. Using an operation platform vehicle that runs along the railway track and carries operation tools for railway maintenance construction can reduce the manual labor intensity, improve efficiency, and effectively utilize the skylight time. There are a wide variety of processes and construction equipment involved in railway maintenance construction, and the functions required for operation tools are also numerous. For example, it is necessary to cooperate with the loading and unloading of materials during construction, grab the hanging basket to assist personnel in high-altitude construction, grab heavier materials and cooperate with personnel to assist in construction, grab inspection operation tools for inspection operations, etc. However, in existing operation platform vehicles, ropes and hooks are used to lift and unload materials, and mechanical claws are used to grab, fix, and transfer objects. Since the space on the boom of a single full-hydraulic telescopic boom crane is limited, the ropes and hooks and the mechanical claws each require a large installation and operation space and need to be installed on the boom of independent full-hydraulic telescopic boom cranes respectively. Otherwise, there will be problems such as inconvenient installation layout and operation, and even interference with each other. This results in the need to set up multiple full-hydraulic telescopic boom cranes for existing operation platform vehicles to achieve multi-functional operations, which has problems such as high cost, complex structure, large occupied space, and inconvenient operation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a multi-functional platform vehicle for railway maintenance that has a simple and compact structure, low cost, convenient operation and control, stable and reliable work, and can achieve a variety of operation functions without interference.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] A multifunctional platform vehicle for railway maintenance comprises a vehicle body and a crane mounted on the vehicle body, a multifunctional connecting device being mounted on the lifting arm of the crane, the multifunctional connecting device comprising a tool joint for mounting a working tool, a rotating seat rotatably mounted on the lifting arm, and a rotating driving member connected to the rotating seat for driving the rotating seat to rotate, the tool joint being connected to the rotating seat via a docking mechanism in a manner capable of docking with and detaching from the rotating seat, the tool joint being fixed relative to the rotating seat when docked with the rotating seat, a lifting rope being connected between the tool joint and the rotating seat, a retracting and releasing mechanism for winding up and releasing the lifting rope being mounted on the rotating seat, the retracting and releasing mechanism being capable of keeping the tool joint docked with the rotating seat when winding up the lifting rope, and allowing the tool joint to detach from the rotating seat when releasing the lifting rope.

[0006] As a further improvement of the above technical solution:

[0007] The docking mechanism comprises a first joint and a second joint which are plugged into and matched with each other, wherein the first joint is arranged on the tool joint, and the second joint is arranged on the rotating seat.

[0008] A guiding mechanism is provided between the tool joint and the rotating seat, which is used to guide the tool joint to move when the retracting mechanism retracts the sling rope so that the first joint and the second joint are plugged and matched.

[0009] The guiding mechanism comprises a folding rod formed by a plurality of connecting rods hinged in sequence, the connecting rod at one end of the folding rod is connected to the tool joint, and the connecting rod at the other end of the folding rod is connected to the rotating seat.

[0010] When the first joint and the second joint are butt-jointed, a receiving space is formed. When the first joint and the second joint are butt-jointed, the folding rod is accommodated in the receiving space.

[0011] The first connector and the second connector are plugged together through a plurality of plug-in positioning mechanisms, wherein the plug-in positioning mechanisms include plug-in posts and plug-in holes, wherein the plug-in posts are arranged on one of the first connector and the second connector, and the plug-in holes are arranged on the other of the first connector and the second connector.

[0015] The working tool comprises a hook and a mechanical clamp.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] The multi-functional platform vehicle for railway maintenance of the present invention is provided with a multi-functional connecting device on the boom of a crane. The tool joint of the multi-functional connecting device can be docked with and disengaged from a rotating seat rotatably mounted on the boom, and a lifting rope is connected between the tool joint and the rotating seat. When docked, the tool joint is fixed relative to the rotating seat, so that the working tool connected to the tool joint can be relatively fixed to the rotating seat. By controlling the movement of the boom and the rotation angle of the rotating seat, the driving of the tool joint and the working tool to move correspondingly can be realized, meeting the grasping and detection operations that require an object to be fixed. When disengaged, the tool joint is separated from the rotating seat and connected to the rotating seat through a lifting rope. At this time, only by installing a working tool such as a hook on the tool joint, the lifting and loading / unloading of materials can be carried out in cooperation with the boom. It only requires one crane to realize various operations such as grasping and transferring materials and lifting and loading / unloading materials, which can reduce costs, improve the simplicity and compactness of the structure, and the convenience of operation. At the same time, the multi-functional connecting device adopts a structural form in which the rotating seat and the tool joint are connected through a docking mechanism.

[0026] As Figures 1 to 5 shown, the multifunctional platform vehicle for railway maintenance in this embodiment includes a vehicle body 1 and a crane 2 installed on the vehicle body 1. A multifunctional connection device is installed on the boom 21 of the crane 2. The multifunctional connection device includes a tool joint 3 for installing working tools, a rotating seat 4 rotatably installed on the boom 21, and a rotation driving member 5 connected to the rotating seat 4 for driving the rotating seat 4 to rotate. The tool joint 3 is connected to the rotating seat 4 through a docking mechanism in a manner that can be docked and disengaged from the rotating seat 4. When the tool joint 3 is docked with the rotating seat 4, it is fixed relative to the rotating seat 4. A lifting rope 6 is connected between the tool joint 3 and the rotating seat 4. A winding and releasing mechanism for winding and releasing the lifting rope 6 is installed on the rotating seat 4. When the winding and releasing mechanism winds the lifting rope 6, the tool joint 3 can be kept docked with the rotating seat 4, and when the lifting rope 6 is released, the tool joint 3 is allowed to disengage from the rotating seat 4.

[0027] For the multifunctional platform vehicle for railway maintenance, a multifunctional connection device is installed on the boom 21 of the crane 2. The tool joint 3 of the multifunctional connection device can be docked and disengaged from the rotating seat 4 rotatably installed on the boom 21. Moreover, a lifting rope 6 is connected between the tool joint 3 and the rotating seat 4. When docked, the tool joint 3 is fixed relative to the rotating seat 4, so that the working tool connected to the tool joint 3 can be relatively fixed to the rotating seat 4. By controlling the movement of the boom 21 and the rotation angle of the rotating seat 4, the corresponding movement of the tool joint 3 and the working tool can be realized, meeting the grasping and detection operations that require the object to be fixed. When disengaged, the tool joint 3 is separated from the rotating seat 4 and connected to the rotating seat 4 through the lifting rope 6. At this time, only working tools such as a hook need to be installed on the tool joint 3, and the boom 21 can be used to cooperate with the lifting and unloading of materials. It can realize multiple operations such as grasping and transferring materials and lifting and unloading materials with only one crane 2, which can reduce costs, improve the simplicity and compactness of the structure, and the convenience of operation. At the same time, the multifunctional connection device adopts a structural form in which the rotating seat 4 and the tool joint 3 are connected through a docking mechanism. On the premise of ensuring the functions of grasping and transferring materials and lifting and unloading materials, it can achieve non-interference with each other, and has a simple structure, low cost, convenient operation, and stable and reliable work. In addition, while having the basic functions of winding and releasing the lifting rope 6, the winding and releasing mechanism can also keep the tool joint 3 docked with the rotating seat 4 by winding the lifting rope 6, which can further improve the simplicity and compactness of the structure and reduce costs.

[0029] In this embodiment, a guide mechanism is provided between the tool joint 3 and the rotating seat 4 for guiding the tool joint 3 to move when the retracting mechanism reels the sling rope 6 so that the first joint 7 and the second joint 8 can be plugged and matched. This ensures that when the retracting mechanism reels the sling rope 6, the first joint 7 and the second joint 8 can be quickly and accurately aligned and plugged into each other.

[0030] In this embodiment, the guide mechanism includes a folding rod member formed by hingedly connecting a plurality of connecting rods 9 in sequence, the connecting rod 9 at one end of the folding rod member is connected to the tool joint 3, and the connecting rod 9 at the other end of the folding rod member is connected to the rotating seat 4. This kind of guide mechanism has a simple structure, low cost, and is easy to manufacture and assemble.

[0031] In this embodiment, a receiving space is formed when the first joint 7 and the second joint 8 are connected, and the folding rod is accommodated in the receiving space when the first joint 7 and the second joint 8 are connected. This is beneficial to improving the compactness and aesthetics of the structure, and also protects the folding rod when the first joint 7 and the second joint 8 are connected.

[0032] In this embodiment, the first connector 7 and the second connector 8 are plugged together through a plurality of plug-in positioning mechanisms, and the plug-in positioning mechanisms include a plug-in column 71 and a plug-in hole. The plug-in column 71 is provided on one of the first connector 7 and the second connector 8, and the plug-in hole is provided on the other of the first connector 7 and the second connector 8.
