Description

Technical Field

[0001] The present invention relates to the technical field of stretcher production and detection, and in particular to an electric control type detection device applied to stretcher production. Background Art

[0002] A stretcher is a medical transportation tool designed specifically for patients with limited mobility or injuries. It is usually made of high-strength materials and is capable of transporting patients from one place to another conveniently and effectively. It is an essential device in medical first aid and rescue operations. Because of its simple structure and wide application fields, it is an important rescue device in medical first aid, outdoor activities and disaster relief.

[0003] At present, during the production and processing of stretchers, load-bearing tests need to be carried out for stretchers of different specifications and uses. However, the traditional load-bearing test only simply detects the stretcher support rods, and cannot simulate the load-bearing state of the stretcher under different conditions. Moreover, it is also impossible to directly conduct detection experiments on the stretcher during the transportation process, resulting in low detection efficiency and insufficiently rich simulation scenarios. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the traditional load-bearing test only simply detects the stretcher support rods, and cannot simulate the load-bearing state of the stretcher under different conditions. Moreover, it is also impossible to directly conduct detection experiments on the stretcher during the transportation process, resulting in low detection efficiency and insufficiently rich simulation scenarios.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an electric control type detection device applied to stretcher production, including a horizontal main frame and an electric control feeding belt installed on the horizontal main frame. The upper end of the horizontal main frame is fixedly installed with an upper detection frame through a top side frame. The upper end of the upper detection frame is installed with a plurality of electric control type retracting and releasing counterweight mechanisms and an optical detection module through a longitudinal side control frame. Electric control type longitudinal lifting mechanisms and electric control type oblique lifting mechanisms are fixedly installed on the outer walls on both sides of the horizontal main frame.

[0006] A bottom cross beam for installing the optical detection module is fixedly assembled inside the upper detection frame.

[0007] Lateral positioning convex blocks for improving the stability of conveying and lifting are fixedly assembled on both sides of the outer surface of the electric control feeding belt.

[0008] Lower infrared positioning modules are fixedly assembled on the lower surface of the upper detection frame corresponding to the positions of the electric control type longitudinal lifting mechanism and the electric control type oblique lifting mechanism. Optical positioning lenses cooperating with the lower infrared positioning modules are fixedly assembled on the upper surface of the lateral positioning convex blocks.

[0009] The electronically controlled weight retracting and extending mechanism includes a lateral cable winding shaft movably installed on the outside of the longitudinal control frame, an electronically controlled lateral drive shaft movably installed at the upper end of the upper detection frame, a worm and worm gear assembly, an external cable wound around the lateral cable winding shaft, and a counterweight sandbag located inside the longitudinal control frame.

[0010] Embedded longitudinal assembly grooves for installing the electronically controlled longitudinal lifting mechanism and embedded oblique assembly grooves for installing the electronically controlled oblique lifting mechanism are provided on the outer walls on both sides of the horizontal main frame.

[0011] Both the electronically controlled longitudinal lifting mechanism and the electronically controlled oblique lifting mechanism are composed of a bottom telescopic strut, a top support frame in a U-shaped structure axially fixed at the telescopic end of the top of the bottom telescopic strut, and a side elastic limit frame fixed on one side of the top support frame.

[0012] A pressure touch module is installed on the side wall of the side elastic limit frame at the connection surface of the top support frame.

[0013] A circular assembly through hole is provided at the upper end inside the longitudinal control frame. An internal adjustment ring is movably assembled inside the circular assembly through hole through a ball bearing. An internal guide wheel is movably assembled inside the internal adjustment ring. The external cable bypasses the internal guide wheel and is connected to the lateral end of the counterweight sandbag.

[0014] An internal cable through hole matching the external cable is provided inside the lateral cable winding shaft. A lateral locking screw hole communicating with the internal cable through hole is provided on the side wall of the lateral cable winding shaft. A locking bolt is threadedly assembled inside the lateral locking screw hole.

[0015] The beneficial effects of the present invention are:

[0016] (1) The electronically controlled detection device applied to stretcher production of the present invention directly lifts and separates the stretcher on the electronically controlled conveying belt through the electronically controlled longitudinal lifting mechanism and the electronically controlled oblique lifting mechanism on both sides of the horizontal main frame, and conducts a simulated load-bearing test while not affecting the stretcher conveying, greatly improving the detection efficiency;

[0017] (2) A plurality of electronically controlled weight retracting and extending mechanisms are installed on the upper detection frame at the upper end of the horizontal main frame through the longitudinal control frame, which can test the stretcher under different load-bearing states, greatly improving the authenticity of the test and making the detection range wider;

[0018] (3) By using the optical detection module on the upper detection frame to cooperate with the optical positioning lens on the lateral positioning convex block, the electronically controlled longitudinal lifting mechanism and the electronically controlled oblique lifting mechanism can be accurately controlled, which is convenient for accurate control and ensures the separation efficiency;

[0019] (4) The electronically controlled retractable counterweight mechanism adopts a laterally winding rope shaft design with synchronous control, which can ensure the synchronous retraction and extension of the external pulling ropes on both sides, greatly improving the transmission efficiency;

[0020] (5) The electronically controlled retractable counterweight mechanism uses counterweight sandbags controlled by external pulling ropes. The downward pressure of the counterweight sandbags can be adjusted according to the retraction and extension of the external pulling ropes, and different load-bearing states can be accurately tested.

[0030] The present invention will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0031] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An electric control type detection device applied to the production of stretchers, as shown in ,

[0032] , Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , includes a horizontal main frame 1 and an electric control feeding belt 2 installed on the horizontal main frame 1. At the upper end of the horizontal main frame 1, an upper detection frame 3 is fixedly installed through a top side frame. At the upper end of the upper detection frame 3, two electric control type retractable counterweight mechanisms 5 and an optical detection module 6 are installed through a longitudinal side control frame 4. Electric control type longitudinal lifting mechanisms 7 and electric control type oblique lifting mechanisms 8 are fixedly installed on the outer walls on both sides of the horizontal main frame 1.

[0033] Working principle: When the stretcher is placed on the surface of the electric control conveyor belt 2, and then when one side support rod of the stretcher is translated above the electric control type longitudinal lifting mechanism 7, the electric control type longitudinal lifting mechanism 7 lifts one side of the stretcher, and then the electric control type oblique lifting mechanism 8 lifts the other side of the stretcher. Then the stretcher is unfolded and lifted to the lower end of the upper detection frame 3, and then is electrically pressed onto the stretcher through the electric control type retractable counterweight mechanism 5. The optical detection module 6 is used to detect the deformation degree of the stretcher, so as to detect the stretcher. By setting a plurality of electric control type retractable counterweight mechanisms 5 and optical detection modules 6, multiple stretchers can be detected one by one.

[0034] The electric control type longitudinal lifting mechanism 7 and the electric control type oblique lifting mechanism 8 have the same structural functions.

[0035] To cooperate with the bottom assembly, a bottom cross beam 9 for installing the optical detection module 6 is fixedly assembled inside the upper detection frame 3.

[0036] The optical detection module 6 emits ranging light downward. When the support rod on the outer side of the stretcher is subjected to load, it will generate a bending deformation. Through the distance change caused by the bending, the optical detection module 6 is used to measure the bending degree of the support rod, so as to judge the load-bearing capacity of the stretcher. At the same time, the deformation degree of the support cloth can also be judged by the stretchable distance between the support rods on both sides of the stretcher.

[0037] To cooperate with the installation and positioning, lateral positioning bumps 10 for improving the conveying and lifting stability are fixedly assembled on both sides of the outer surface of the electric control feeding belt 2.

[0038] To cooperate with optical positioning, lower infrared positioning modules 11 are fixedly assembled on the lower surface of the upper detection frame 3 corresponding to the positions of the electric longitudinal lifting mechanism 7 and the electric oblique lifting mechanism 8. An optical positioning lens 12 that cooperates with the lower infrared positioning module 11 is fixedly assembled on the upper surface of the lateral positioning bump 10.

[0039] The support rods on both sides of the stretcher are placed on one side of the lateral positioning bump 10. A lateral control paddle for controlling the optical positioning lens 12 is elastically installed on one side of the lateral positioning bump 10. By pressing the lateral control paddle, the optical positioning lens 12 can be flipped to cooperate normally with the lower infrared positioning module 11, facilitating the reflection of the infrared rays emitted downward by the lower infrared positioning module 11 upward, and facilitating the lower infrared positioning module 11 to receive infrared signals.

[0040] To cooperate with electric control adjustment for testing the load-bearing capacity, the electric retractable counterweight mechanism 5 includes a lateral winch shaft 51 movably installed outside the longitudinal side control frame 4, an electric lateral drive shaft 52 movably installed at the upper end of the upper detection frame 3, a worm and worm gear assembly 53, an external pull rope 54 wound around the lateral winch shaft 51, and a counterweight sandbag 55 located inside the longitudinal side control frame 4.

[0041] The worm and worm gear assembly 53 includes a driving worm axially fixed at both ends of the electric lateral drive shaft 52 and a driven worm axially fixed at both ends of the lateral winch shaft 51. The driving worm meshes with the driven worm for transmission. In this way, the electric lateral drive shaft 52 can synchronously drive the lateral winch shafts 51 on both sides to rotate and adjust, and then use the lateral winch shaft 51 to retract and release the external pull rope 54, thereby adjusting the height of the counterweight sandbag 55. By squeezing the stretcher below with the counterweight sandbag 55, the load-bearing capacity and anti-deformation degree of the stretcher can be detected through the bending degree on both sides of the stretcher.

[0042] To cooperate with lateral assembly and improve the installation firmness, embedded longitudinal assembly grooves for installing the electric longitudinal lifting mechanism 7 and embedded oblique assembly grooves for installing the electric oblique lifting mechanism 8 are provided on the outer walls of both sides of the horizontal main frame 1.

[0043] To cooperate with telescopic control, both the electric longitudinal lifting mechanism 7 and the electric oblique lifting mechanism 8 are composed of a bottom telescopic support rod 781, a top support frame 782 with a U-shaped structure axially fixed at the top telescopic end of the bottom telescopic support rod 781, and a side elastic limit frame 783 fixed on one side of the top support frame 782.

[0044] The bottom telescopic support rod 781 controls the lifting of the top support frame 782 and the side elastic limit frame 783 fixed on one side of the top support frame 782 through telescoping. The top support frame 782 supports and limits the two ends of the support rod on the outside of the stretcher to prevent it from detaching from the outside in the lifted state.

[0045] The telescopic section of the bottom telescopic support rod 781 is staggered from the support rods on both sides of the stretcher, without affecting the subsequent translation of the stretcher.

[0046] In order to cooperate with the monitoring of the pressure on the contact surface and facilitate control, a pressure touch module 13 is installed on the side wall of the side elastic limit frame 783 at the connection surface of the top support frame 782.

[0047] Normally, the stretcher is placed on the electric control feeding belt 2 in a horizontally laid manner. The lower infrared positioning module 11 emits infrared rays downward and receives the infrared rays it emits through the reflection of the optical positioning lens 12. Once the stretcher translates past, the infrared rays will be blocked. At this time, the electric control longitudinal lifting mechanism 7 will extend, controlling the side elastic limit frame 783 at its upper end to lift, and then contacting the support rod on one side of the stretcher. The stretcher squeezes the side elastic limit frame 783, and the side elastic limit frame 783 bends, and the pressure of the pressure touch module 13 becomes smaller. At this time, the electric control oblique lifting mechanism 8 will be activated. The electric control oblique lifting mechanism 8 controls the top support frame 782 to squeeze the support rod on the other side of the stretcher upward, and then lifts the stretcher to the bottom of the upper detection frame 3.

[0048] In order to cooperate with the top guide rope and reduce the friction, a circular assembly through hole is opened at the upper end inside the longitudinal side control frame 4. An internal adjustment ring 14 is movably assembled inside the circular assembly through hole through a ball bearing. An internal guide wheel 15 is movably assembled inside the internal adjustment ring 14. The external pull rope 54 bypasses the internal guide wheel 15 and is connected to the lateral end of the counterweight sandbag 55.

[0049] In order to cooperate with the bolt locking and fixing, an internal rope passing through hole 16 that matches the external pull rope 54 is opened inside the lateral rope winding shaft 51. A lateral locking screw hole communicating with the internal rope passing through hole 16 is opened on the side wall of the lateral rope winding shaft 51. A locking bolt 17 is threadedly assembled inside the lateral locking screw hole.

[0050] Insert the outer end of the external pull rope 54 into the internal rope passing through hole 16, and then screw the locking bolt 17 into the lateral locking screw hole to lock the external pull rope 54 in the internal rope passing through hole 16.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
