Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present utility model.

The locking and unlocking objects in the embodiment of the utility model are square wire clamps from the electromagnet module of the maglev train to the middle part of the electric junction box. The wire clamps between the electromagnet modules of the maglev train and the middle part of the electric junction box are provided with a plurality of layers. Each wire clamping hole comprises an upper clamping plate and a lower clamping plate. When in installation, the lower half part of the clamping plate is firstly placed in the installation groove, the cable and the sheath are clamped into the clamping plate, the upper half part of the clamping plate is placed, and then the bolts are placed in the installation holes. In practice, because the wiring is more, therefore, usually contain a plurality of clamp line holes on every layer of splint, at first carry out first layer connector pre-fixation, install first layer splint, put into the mounting groove with splint lower half, put into splint with cable and sheath card in proper order, put into first half splint, for fixed upper and lower part splint, put into the mounting hole with the bolt.

When the bolts are installed in the installation holes, the wire clamps from the electromagnet modules of the maglev train to the middle part of the electric junction box are positioned in the interlayer of the car body equipment, so that the installation space is narrow, and the fastening difficulty is high; the wire clamp is composed of a plurality of components, and is complex to assemble; the number of wires in the wire clamp is large and the wire diameter is large. Therefore, the clamping plate locking and the clamping plate unlocking of the bolt removing are difficult and low in efficiency due to the influence of factors such as space, structure and number of wire harnesses.

According to the embodiment of the utility model, the clamping plate locking and unlocking is conveniently realized by the electric tightening and the bolt removing through the wire clamp locking and unlocking device comprising the controller, the motor and the threaded stud, namely the electric wire clamp locking and unlocking device, and the clamping plate locking and unlocking efficiency is improved.

The core of the utility model is to provide a wire clamp locking and unlocking device and wire clamp locking and unlocking equipment, so as to solve the technical problems of high difficulty and low efficiency in realizing clamping plate locking by manually tightening a bolt and realizing clamping plate unlocking by removing the bolt.

In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the accompanying drawings and detailed description. Fig. 1 is a schematic diagram of a wire clamp locking and unlocking device according to an embodiment of the present utility model, as shown in fig. 1, the device includes: the device comprises a controller 1, a motor 2 and a threaded stud 3;

the controller 1 is connected with the motor 2;

the first end of the stud 3 is in contact with the motor 2;

the second end of the stud 3 is contacted with a bolt 5 in a mounting hole 4 on the wire clamp to be locked or the wire clamp to be unlocked; the wire clamp to be locked or the wire clamp to be unlocked is positioned between the magnetic levitation train electromagnet module and the electric junction box, and threads are arranged in the mounting holes 4.

In the embodiment of the present utility model, the end of the stud 3 contacting the motor 2 is referred to as a first end of the stud 3, and the end of the stud 3 contacting the bolt 5 in the mounting hole 4 is referred to as a second end of the stud 3. In order to ensure that the bolt 5 can adjust the coupling action with the internal thread of the mounting hole 4 under the rotation action of the stud 3, in practice, the diameter of the portion of the stud 3 near the second end of the stud 3 is smaller than or equal to the diameter of the mounting hole 4.

In the wire clamp locking and unlocking device, a motor 2 is in contact with a threaded stud 3, the stud 3 is in contact with a bolt 5, and the bolt 5 is positioned in a threaded mounting hole 4. The motor 2 can drive the stud 3 to rotate when rotating, the rotation of the stud 3 further drives the bolt 5 to rotate, and the rotation of the bolt 5 can change the coupling effect between the threads in the mounting hole 4 where the bolt 5 is positioned and the threads on the bolt 5, specifically, when the motor 2 respectively generates torque in the positive and negative directions, the torque is transmitted to the bolt 5, so that the bolt 5 can rotate in two directions. When the bolt 5 rotates in one direction (such as clockwise), the coupling effect between the threads in the mounting hole 4 where the bolt 5 is positioned and the threads on the bolt 5 is enhanced, namely, the locking and fastening of the wire clamp are realized; when the bolt 5 is rotated in the other direction (e.g., counterclockwise), the coupling between the threads in the mounting hole 4 where the bolt 5 is located and the threads on the bolt 5 is reduced, i.e., the wire clamp is unlocked.

In the implementation, in order to lock or unlock the wire clamp, the wire clamp locking installation or unlocking parameters can be set on control, and the locking or unlocking position value, the torsion value and the rotation speed value are set in advance. Taking a locking three-layer clamping plate, wherein each layer of clamping plate comprises three mounting holes 4 as an example, after three bolts 5 are placed into the three mounting holes 4, a wire clamp locking and unlocking device is placed at the first layer of clamping plate, and three bolts 5 are fastened in sequence by pressing a starting key, so that the first layer of clamping plate is mounted. And then the locking of the second layer of clamping plates and the third layer of clamping plates is completed in sequence.

Compared with the mode of manually tightening the bolt to realize the clamping plate locking and the mode of removing the bolt to realize the clamping plate unlocking before, the wire clamp locking and unlocking device provided by the embodiment of the utility model can conveniently realize the clamping plate locking and unlocking by electrically tightening and removing the bolt, and improves the efficiency of the clamping plate locking and unlocking.

When the wire clamp locking and unlocking device is used, if a user directly holds the wire clamp locking and unlocking device, the stud 3 is aligned with the bolt 5 in the mounting hole 4, the space is limited, and the safety is considered, and in one embodiment, the wire clamp locking and unlocking device further comprises a supporting device; the stud 3 passes through the support means. The structure of the supporting means is not limited. If the supporting device is in a T-shaped structure, for convenience in description, the upper part of the T-shaped structure is called a non-connecting end, the lower part of the T-shaped structure is called a connecting end (because of the need of connecting with the stud 3), and the stud 3 is supported through the connecting end of the T-shaped structure; the support means may also be an F-clamp. Fig. 2 is a structural diagram of a wire clamp locking and unlocking device according to an embodiment of the present utility model, and fig. 3 is a side view of the wire clamp locking and unlocking device shown in fig. 2. As shown in fig. 2 and 3, the wire clamp locking and unlocking device comprises a controller 1, a motor 2, a threaded stud 3 and a supporting device, wherein the supporting device is an F-shaped clamp. Specifically, the F-shaped clamp comprises a clamp rod 6, a first clamp arm 7 and a second clamp arm 8; the first clamp arm 7 and the second clamp arm 8 are parallel to each other and are perpendicular to the clamp rod 6; the first end of the second clamp arm 8 is in contact with the clamp bar 6; the stud 3 passes through the second end of the second clamp arm 8. When using an F-clamp as a support means, the inner side of the first clamp arm 7 of the F-clamp is in contact with the bottom end of the lower half of the wire clamp. Compared with the supporting device with the T-shaped structure, as the inner side of the first clamp arm 7 of the F-shaped clamp can be in contact with the bottom end of the lower half part of the wire clamp, when the wire clamp is fastened through the motor 2, a certain fixing effect can be achieved, the upper part and the lower part of the wire clamp can be aligned as much as possible, and the wire clamp is locked and fastened.

Compared with the supporting device with the T-shaped structure, the F-shaped clamp has a certain fixing effect when the upper clamping plate and the lower clamping plate are locked, and meanwhile the F-shaped clamp has a supporting effect, so that the F-shaped clamp is selected as the supporting device in a preferred embodiment.

On the basis of the above embodiment, in order to accommodate the tightening of the bolts 5 in the mounting holes 4 in different positions, in one embodiment the second clamp arm 8 is provided with telescopic means, and/or rotation means, and/or translation means.

The structure and the installation position of the telescopic mechanism and/or the rotating mechanism and/or the translating mechanism provided on the second clamp arm 8 are not limited as long as the telescopic, rotatable and translatable second clamp arm 8 can be realized. The adjustable bolt 5 is aligned with the bolt 5 in the mounting hole 4 as far as possible through the extension, rotation and translation of the second clamp arm 8, so that the bolt 5 and the internal threads of the mounting hole 4 are fastened or the bolt 5 is removed under the action of the motor 2, and further the fastening or unlocking of the upper and lower part clamps is realized.

In the process of fastening the wire clamp, the motor 2 drives the stud 3 to rotate, and the stud 3 drives the bolt 5 to rotate, so that the locking of the bolt 5 and the threads in the mounting hole 4 is realized. In practice, the situation that the stud 3 excessively presses the bolt 5 in the mounting hole 4 may occur, so that the position of the mounting hole 4 on the wire clamp is excessively recessed, and the surface of the wire clamp is uneven, so in one embodiment, the wire clamp locking and unlocking device further comprises a limiting device 9; the limiting device 9 is located on the stud 3 and is close to the second end of the stud 3.

The function of the limiting means 9 is to limit the position of the stud 3 into the mounting hole 4 so that the bolt 5 is not pressed into a deeper position in the mounting hole 4. The structure of the stopper 9 is not limited as long as it can restrict the position of the stud 3 into the mounting hole 4. The limiting device 9 is located on the stud 3 and is close to the second end of the stud 3, and can be only in surface contact with part of the stud 3 or can be in contact with the periphery of the stud 3. In practice, if the limiting device 9 is disposed on the stud 3 and is close to the second end of the stud 3 and is in surface contact with a portion of the stud 3, under the action of the stud 3, the stud 3 is relatively under a relatively small pressure on the side where the limiting device 9 exists by the bolt 5, and the stud 3 is under a relatively large pressure on the side where the limiting device 9 does not exist, so that the stress on the whole stud 3 is uneven, the situation that the threads in the mounting hole 4 cannot be completely matched with the bolt 5 occurs, and the fastening degree of the wire clamp is poor. Thus, the preferred stop means 9 is a stop means 9 located on the stud 3 near the second end of the stud 3 in contact with a perimeter of the stud 3. In one embodiment, the limiting device 9 in the wire clamp locking and unlocking device is a limiting device 9 with a cylindrical structure; the stud 3 passes through the centre of the limit device 9 of cylindrical structure. As shown in fig. 2 and 3, the limiting device 9 is sleeved on the stud 3. When the limit device 9 of the cylindrical structure plays a limiting role, the surface of the limit device 9 of the cylindrical structure, which is close to the second end of the stud 3, is in contact with the surface where the upper half part of the wire clamp is located.

In order to make the position of the bolt 5 clear when locking or unlocking the wire clamp, in one embodiment, the wire clamp locking and unlocking device further comprises a distance measuring device 10; the distance measuring device 10 is positioned in the limiting device 9 and is connected with the controller 1.

The distance measuring device 10 as used is a laser distance measuring device. The laser ranging device is arranged in the limiting device 9, the laser ranging device is connected with the controller 1, and the distance between the bolt 5 and the laser ranging device is detected. In practice, a distance threshold value may be set, which represents the minimum distance between the bolt 5 and the laser distance measuring device, which distance characterizes the distance between the bolt 5 and the laser distance measuring device when the locking is completed. Under the condition that the distance between the bolt 5 and the laser distance measuring device is detected to be smaller than a distance threshold value, the fact that tight coupling between the threads of the bolt 5 and the threads in the mounting hole 4 is completed is indicated to be completed, namely the locking and fastening of the wire clamp are completed, and at the moment, the controller 1 can control the motor 2 to stop rotating; when the distance between the bolt 5 and the laser distance measuring device is detected to be greater than or equal to the distance threshold value, the tight coupling between the threads of the unfinished bolt 5 and the threads in the mounting hole 4 is indicated, namely the unfinished wire clamp is locked and fastened, and at the moment, the controller 1 can control the motor 2 to continue to rotate so as to lock and fasten the wire clamp. When the locking and unlocking device of the clip realizes the locking action, the structure composed of the controller 1, the motor 2, the stud 3, the limiting device 9 and the distance measuring device 10 can be also called as an electric screw propulsion device.

The wire clamp locking and unlocking device comprising the distance measuring device provided by the embodiment enables the locking process to be known according to the distance between the bolt measured by the distance measuring device and the distance measuring device, and the locking degree to be accurately controlled according to the distance value.

In order to facilitate the user to intuitively know the locking position, the torque value, the rotation speed value and the like of the motor 2 in the locking or unlocking process, the wire clamp locking and unlocking device also comprises a display screen; the display screen is connected with the controller 1.

In addition, after the distance is measured by the laser ranging device in the above embodiment, the distance data can be displayed on the display screen, so that a user can conveniently know the data in the locking or unlocking process.

Likewise, in order to facilitate the user to intuitively understand the locking or unlocking process, the wire clamp locking and unlocking device also comprises a prompting device; the prompting device is connected with the controller 1.

The structure of the presentation device, the scene when the presentation device issues the presentation, the frequency of the presentation by the presentation device, and the like are not limited as long as the presentation function can be achieved. The prompting device can be an indicator lamp, a buzzer and the like. The prompting device can prompt when locking is completed or prompt when locking is not completed within a period of time. The presentation device may continue to present the presentation after the presentation scene is detected, or may present the presentation at a fixed frequency.

The wire clamp locking and unlocking device comprising the prompting device provided by the embodiment enables a user to intuitively understand the self-locking or unlocking process and initially understand the problems occurring in the self-locking or unlocking process according to prompting information of the prompting device through prompting action of the prompting device.
