Description

Technical Field

[0001] The utility model relates to the technical field of homing and locking of a machine head cross arm assembly, in particular to a homing and locking structure of a mobile DR. Background Art

[0002] When the mobile DR is not in operation, the fixed head cross arm assembly needs to be returned to its original position and locked. Therefore, a return locking structure needs to be adapted on the fuselage to facilitate the promotion, transportation, and storage of the mobile DR. Conventional return locking structures generally have two forms: one is a purely mechanical type. Although the locking structure has high reliability, the operation is complicated. The locking mechanism needs to be manually started when the return lock is made and the lock is opened again. The other is a contact-sensing electric return locking structure. Although this structure is easy to operate and the start and close of the locking return mechanism can be controlled by the switch at the push handle position, it is easy to trigger by mistake and has poor locking reliability. That is, the return locking structure of the head cross arm assembly of the existing mobile DR has the following problems: 1. The return locking structure of the purely mechanical type is complicated to operate. Since the lock structure is usually close to the side of the column, the return locking structure is manually operated. The operator has to leave the push position and walk to the other side of the equipment to operate, and the operation process is too cumbersome. 2. The contact-sensing electric return locking structure triggers the locking structure after the locking rod contacts the micro switch. This structure has high requirements on the accuracy of return, and there is a risk of misoperation, and the reliability of locking is limited. In view of the above problems, a return locking structure of a mobile DR is proposed, which has higher reliability and is convenient to operate. Summary of the invention

[0003] The purpose of the present application is to provide a homing locking structure for a mobile DR.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a return locking structure for a mobile DR, comprising a fixed bracket, characterized in that it also comprises a mechanical buckle and a mechanical buckle connecting block, the mechanical buckle connecting block is installed on the fixed bracket, the mechanical buckle connecting block has a groove for placing the locking rod in the return position, the middle part of the mechanical buckle is rotatably connected to the mechanical buckle connecting block, one end of the mechanical buckle is a locking end, and the locking end can lock the locking rod in the groove, the other end of the mechanical buckle is an adjusting end, and the weight of the adjusting end is greater than the weight of the locking end, the fixed bracket is installed with a detection switch for detecting whether the locking rod is placed in the groove, and the fixed bracket is also installed with an electric drive component that can drive the adjusting end to move upward.

[0005] The middle part of the mechanical buckle is rotatably connected to the mechanical buckle connecting block through a pin shaft.

[0006] The electric drive member is a push rod type electromagnet or an electric push rod.

[0007] The detection switch is a travel micro switch or a photoelectric switch.

[0008] The groove has an inclined surface.

[0009] The locking rod is installed on the machine head cross arm assembly.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] 1. It is easier to operate. The operator of the mobile DR can directly perform the return locking operation at the pushing position, and the starting and closing operations of the locking structure are more convenient.

[0012] 2. High reliability. The triggering of the lock does not rely on electrical components, but relies on a unique mechanical structure for automatic locking. At the same time, the lock release button can only be triggered after the return locking structure is locked. This structure can effectively prevent false triggering, and has higher reliability and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1-Figure 3As shown, the return locking structure of the mobile DR includes a fixed bracket 5, a mechanical buckle 1 and a mechanical buckle connecting block 2. The mechanical buckle connecting block 2 is installed on the fixed bracket 5. The mechanical buckle connecting block 2 has a groove 2a for placing the locking rod 7 in the return position. Specifically, the groove 2a has an inclined surface; the middle part of the mechanical buckle 1 is rotatably connected to the mechanical buckle connecting block 2, specifically, the middle part of the mechanical buckle 1 is rotatably connected to the mechanical buckle connecting block 2 through a pin shaft 3; one end of the mechanical buckle 1 is a locking end, and the locking end can lock the locking rod 7 in the groove 2a, and the other end of the mechanical buckle 1 is an adjusting end, and the weight of the adjusting end is greater than the weight of the locking end. The mechanical buckle 1 can be flexibly rotated through the pin shaft 3. Since the center of gravity of the mechanical buckle 1 is arranged at the tail end, the mechanical buckle 1 is naturally in a state without external force. Figure 3 mounted on the fixed bracket 5 for detecting whether the locking rod 7 is placed into the groove 2a of the detection switch 4, the fixed bracket 5 is also mounted on the electric drive member 6 can drive the regulating end upward movement.

[0020] The electric drive component 6 is a push rod type electromagnet or an electric push rod. In the present embodiment, the electric drive component 6 is a push rod type electromagnet; of course, in practice, other electric drive components 6 can still achieve the same effect.

[0021] The detection switch 4 is a travel micro switch or a photoelectric switch. In the present embodiment, the detection switch 4 is a travel micro switch. Of course, in practice, other detection switches 4 can still achieve the same effect.

[0022] The locking rod 7 is installed on the machine head cross arm assembly.

[0023] The electric drive member 6 and the detection switch 4 are electrically connected to the control module of the mobile DR, which adopts the existing technology and its circuits do not need to be redesigned.

[0024] During operation, when the head cross arm assembly of the mobile DR needs to be returned to its position and locked, the locking rod 7 fixed on the mobile DR moves downward. When the locking rod 7 contacts the mechanical buckle 1, the locking rod 7 can push the mechanical buckle 1 to move counterclockwise around the pin shaft 3. At this time, the locking rod 7 can continue to move downward to the bottom of the groove 2a of the mechanical buckle connecting block 2, thereby triggering the detection switch 4; when the locking rod 7 moves to the bottom of the groove 2a of the mechanical buckle connecting block 2, the mechanical buckle 1 automatically returns to its position under the action of gravity. Figure 3The state shown in the figure locks the locking rod 7; when the locking state needs to be released, the starting button of the mobile DR head assembly is activated, and the electric drive component 6 causes the mechanical buckle 1 to move counterclockwise, thereby releasing the locking state; when the locking rod 7 moves downward to the locking state, the locking rod 7 triggers the detection switch 4, and the detection switch 4 sends an electrical signal. After the control system of the mobile DR receives the electrical signal, the button can start the electric drive component 6 when the locking state is released, thereby preventing accidental touch operations and having higher reliability and safety.

[0025] In summary, the homing locking structure has the following advantages: 1. It is more convenient to operate and can automatically complete the homing locking of the mobile DR; 2. It can effectively solve various risks caused by accidental touch and misoperation, and has higher reliability and safety.

[0026] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
