Abstract
Description
Technical Field
[0001] The utility model patent relates to the field of parachute training, and in particular to an oblong movable parachute manipulation training simulation device. Background Art
[0002] Skydiving, also known as airborne or parachute landing, is both a sport and a military activity. Skydivers adjust direction in the air, move laterally, and close the vents of the parachute bag when landing. These operations can adjust direction, avoid obstacles, prevent collisions between skydivers, and adjust landing points. These are all important operations related to the safety of skydivers. These operations often require simulated training on the ground. Only by being proficient in the operations can you avoid panic and mistakes in the air and avoid skydiving accidents.
[0003] The realistic airborne simulation simulates the following actions: 1. Pulling the left rear control stick simulates a leftward rotation of the parachute pack, while pulling the right rear control stick simulates a rightward rotation. 2. Pulling the right front and left rear control sticks simultaneously simulates an accelerated leftward rotation of the parachute pack, while pulling the left front and right rear control sticks simultaneously simulates an accelerated rightward rotation. 3. The lower the control sticks are pulled, the faster the parachute pack rotates. Pulling the two rear corner control sticks simultaneously prevents the parachute pack from rotating, simulating braking during landing. 4. Pulling the control straps on one side of the parachute pack, which control lateral movement, causes the parachute pack to move laterally toward the straps. 5. Pulling one control stick to rotate the parachute pack to the desired angle, then releasing the stick, causes the parachute pack to stop rotating and automatically move forward. It should be noted that the control sticks are part of the parachute pack itself, consisting of the lower control stick and the control rope connected to the upper end.
[0004] Furthermore, during transport aircraft parachuting, inertia forces the jumper to float in one direction for a certain distance, regardless of how the parachute is controlled. Current parachuting simulators simply suspend the jumper on a portal-shaped frame and rotate it, but the rotation is stationary, significantly different from actual operation. Furthermore, each frame can only accommodate one or two people, making it impossible to conduct simultaneous parachute training for squads, platoons, or even companies. Developing a highly realistic simulation of aerial floating motion has become a topic of mutual concern and research for the military and related companies, with a strong sense of urgency and mission.
[0005] In short, there is currently a lack of simulated parachute manipulation training equipment that can simulate aerial floating movements and multiple people's simultaneous training. Utility Model Content

[0016] Preferably, the lower end of the first connecting shaft has a thread, and two fastening nuts are screwed onto the lower end of the first connecting shaft.
[0017] The present invention provides an oblong mobile parachute manipulation training simulator. Each transverse guide rail can be suspended with a simulated parachute manipulation training unit with a pulley mechanism. Since multiple transverse guide rail units are provided between the inner and outer track units, the device can meet the requirements for simultaneous use by squads, platoons, and even companies. By controlling the operation of the first track running mechanism of each transverse guide rail unit, each transverse guide rail moves along the inner and outer track units, and the parachutist on the simulated parachute manipulation training unit follows the movement, simulating the parachutist's floating motion in the air due to inertia after parachuting. The parachutist then performs corresponding operations based on the functions of the simulated parachute manipulation training unit. The transverse guide rail includes an upper truss and a first C-shaped steel track fixed to the bottom of the truss. The provision of the truss can greatly enhance the structural strength of the transverse guide rail, reduce the degree of deformation of the transverse guide rail, and ensure the normal use of the transverse guide rail.
[0018] Furthermore, the first track walking mechanism includes a driven walking mechanism and an active walking mechanism connected to the driven walking mechanism through a hinged structure. The driven walking mechanism is responsible for lifting the transverse guide rail, and the active walking mechanism is responsible for driving the moving walking mechanism to move. The hinged structure connection can avoid stress and jamming between the active walking mechanism and the driven walking mechanism in the process of passing through the curve. The driven walking mechanism adopts three sleeves to be connected to the corresponding first pulley mechanism and the vertical fixing member respectively, so as to avoid stress damage caused by the lack of synchronization of the first track walking mechanism at both ends of the transverse guide rail and jamming of the first pulley mechanism on the track.
[0019] Furthermore, for the I-shaped guide rail, the walking motor is installed on one side of the roller to drive the roller shaft, which is unstable and often requires a walking motor on each side. In the solution of the present application, the walking motor is placed under the track, and the active walking mechanism is driven to move along the track by rubbing the bottom of the guide rail with a cylindrical driving wheel, thereby pushing the active walking mechanism to move along the track. Since the cylindrical driving wheel is located directly below the track, the operation is smoother and only one walking motor is required. In addition, in order to prevent falling, the airborne simulation training device often prefers C-shaped steel guide rails, and the rollers can be placed inside the C-shaped steel guide rails. Since the internal space of the C-shaped steel guide rails is limited, how to drive the simulated parachute control training unit to move along the guide rails is a difficult problem. The walking motor is placed under the guide rail, and the problem is well solved by rubbing the bottom of the guide rail with a cylindrical driving wheel.
[0020] Furthermore, one side of the walking motor base plate is hinged and the other side is provided with a cylindrical spring seat and an adjustable height compression spring. The compression spring presses the walking motor base plate to press the cylindrical drive wheel of the walking motor to fit the bottom of the guide rail. Due to the limiting effect of the hinged structure, compared with the spring structure set at both ends, there will be no shaking in the left and right directions, and it is more stable.
[0021] Furthermore, the structure of the vertical fixing piece is very strong and can realize the rotation requirement of the connecting cylinder. The top of the second connecting shaft passes through the corresponding sleeve and the diameter of the stop edge is larger than the inner diameter of the corresponding sleeve, so that the vertical fixing piece is hung on the driven walking mechanism through the stop edge.
[0022] Furthermore, a vertical upper reinforcing plate is fixed between the horizontal hanging plate and the connecting tube, and a vertical lower reinforcing plate is fixed on the transverse guide rail, which further enhances the structural strength of the connection between the vertical fixing member and the transverse guide rail and the structural strength of the vertical fixing member itself.
[0023] Furthermore, the hinge structure includes a first hinge plate fixed to the rear ends of the two vertical plates, a connecting plate fixed to the second pulley mechanism, a second hinge plate fixed to the connecting plate, and a hinge shaft vertically inserted into the first hinge plate and the second hinge plate.
[0024] Furthermore, both the inner ring track unit and the outer ring track unit include an upper reinforcing beam and a second C-shaped steel track with an opening facing downward fixed to the bottom surface of the reinforcing beam, so that the roller can be placed inside the C-shaped steel guide rail, which has a better effect in preventing it from falling off. The upper reinforcing beam can enhance the structural strength of the inner and outer ring track units, reduce the overhang of the deformation gauge, and ensure that the track is reliable and practical.
[0025] Furthermore, since the roller-type consumables need to be replaced in time, the second C-shaped steel track is provided with a detachable section, which can easily remove the vertical hanger and the rollers on both sides of the vertical hanger. Fixed plates are fixed on the horizontal sides of the detachable section, and the fixed plates are fixed to the second C-shaped steel track adjacent to the detachable section by bolts, realizing the detachable function of the detachable section and strengthening the structural strength of the location, ensuring that after the detachable section is installed, the rollers can pass through the detachable section safely and smoothly.
[0026] Furthermore, the lower end of the first connecting shaft has a thread, and two fastening nuts are screwed on the lower end of the first connecting shaft for disassembling the first connecting shaft and for supporting the vertical plates arranged in parallel. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1
[0033] An oblong mobile parachute maneuvering training simulator, such as Figure 1-5 As shown, it includes an oblong outer ring track unit 2, a first L-shaped hanger 5 evenly distributed along the outer side of the outer ring track unit, an oblong inner ring track unit 1, a second L-shaped hanger 4 evenly distributed along the inner side of the inner ring track unit, and a plurality of transverse guide rail units 3 connected between the inner ring track unit and the outer ring track unit. In this embodiment, the outer ring track unit 2 and the inner ring track unit 1 both include semicircular track segments at both ends and straight track segments connecting the semicircular track segments. The transverse guide rail unit includes a transverse guide rail, two vertical fixing members 9 respectively fixed to the top of the two ends of the transverse guide rail, a first track running mechanism rotatably connected to the vertical fixing member at the outer end of the transverse guide rail, and a second track running mechanism rotatably connected to the vertical fixing member at the inner end of the transverse guide rail.

The first L-shaped hanger is fixedly connected to the top of the outer ring track unit, and the second L-shaped hanger is fixedly connected to the top of the inner ring track unit.
[0034] In this embodiment, the first track walking mechanism includes a driven walking mechanism 10 and an active walking mechanism 8 connected to the driven walking mechanism through a hinge structure. The driven walking mechanism includes two vertical plates 19 arranged parallel to the extension direction of the track, three sleeves clamped between the two vertical plates, and two first pulley mechanisms 20 for hanging on the track. The three sleeves are respectively located at the two ends and the middle of the two vertical plates. The lower ends of the two first pulley mechanisms are fixed with first connecting shafts, and the two first connecting shafts are rotatably plugged and fixed in the corresponding sleeves 40 at the two ends of the vertical plates. The top of the vertical fixing part has a second connecting shaft, and the second connecting shaft is rotatably connected to the corresponding sleeve in the middle of the vertical plate; the second track walking mechanism has the same structure as the driven walking mechanism and will not be repeated here. Specifically, the vertical fixings include a horizontal hanger plate 25 fixed to the top of the transverse guide rail, a connecting tube 41 welded to the upper surface of the horizontal hanger plate, and a second connecting shaft inserted and fixed into the connecting tube. The connecting tube is provided with radial pin holes. The second connecting shaft has a retaining edge at the top and a radial insertion hole at the bottom. The pin passes through the pin hole and the insertion hole to secure the lower end of the second connecting shaft to the connecting tube. The top of the second connecting shaft passes through a corresponding sleeve, and the retaining edge 18 has a diameter larger than the inner diameter of the corresponding sleeve. A vertical upper reinforcing plate 28 is fixed between the horizontal hanger plate 25 and the connecting tube, and a vertical lower reinforcing plate 27 is fixed to the transverse guide rail. The transverse guide rail includes an upper truss 45 and a first C-shaped steel track 26 fixed to the bottom of the truss. Specifically, the truss has horizontal sections at each end, with connecting flange plates 46 fixed to the upper surface of the horizontal sections. The lower reinforcing plate 27 is fixed to the connecting flange plates and the truss. The horizontal sections at each end of the truss are fixed to the corresponding horizontal hanger plates 25 via the connecting flange plates 46 and bolts. The horizontal sections at each end of the truss can also be welded to the corresponding horizontal hanger plates 25. The truss structure can greatly enhance the structural strength of the transverse guide rail, reduce the deformation of the transverse guide rail, and ensure the normal use of the transverse guide rail. The truss structure is an existing technology and will not be described in detail here.
[0035] The active travel mechanism includes a second pulley mechanism 14 for hanging on the track, a support plate 43 fixed to the bottom of the second pulley mechanism, a travel motor 42 that drives the second pulley mechanism to roll on the guide rail, and an adjustable elastic unit supporting the travel motor. The adjustable elastic unit is fixed to the upper surface of the support plate. A cylindrical drive wheel 44 is fixed to the output shaft of the travel motor, and the cylindrical drive wheel is pressed against the bottom of the track. The adjustable elastic unit includes a travel motor base plate 33, at least two cylindrical spring seats 37 arranged in the front-to-back direction and located below one side of the travel motor base plate, and a compression spring 38 disposed in the cylindrical spring seat. A guide shaft is provided on the lower surface of the travel motor base plate for inserting into the compression spring. The bottom of the cylindrical spring seat is provided with a top plate 36 for adjusting the bottom of the compression spring. The bottom of the top plate is connected to an adjustment bolt 35, which is screwed onto the support plate. The other end of the travel motor base plate is hingedly fixed to the upper surface of the support plate. Specifically, the other side of the travel motor base plate is connected to a hinge plate 32, the other end of which is hinged to a hinge seat 31, which is fixed to the upper surface of the support plate. One side of the travel motor base plate is hinged, and the other side rests on a cylindrical spring seat and a second, height-adjustable compression spring. The compression spring presses against the travel motor base plate, pressing the travel motor's cylindrical drive wheel against the bottom of the guide rail. Due to the limiting effect of the hinged structure, compared to a system with springs at both ends, there is no left-right wobble, resulting in greater stability.
[0036] The hinge structure includes a first hinge plate 17 fixed to the rear ends of the two upright plates, a connecting plate 29 fixed to the second pulley mechanism, a second hinge plate 15 fixed to the connecting plate, and a hinge shaft 16 vertically inserted between the first and second hinge plates. The connecting plate 29 is vertically arranged, while the first and second hinge plates 17 and 15 are horizontally arranged. The first hinge plate 17 has two parallel plates, and the second hinge plate 15 is inserted between the two parallel plates.
[0037] Both the inner and outer track units include an upper reinforcement beam 13 and a second C-shaped steel track 12 fixed to the bottom surface of the reinforcement beam, with an opening facing downward. The reinforcement beam can be a square tube beam, an I-beam, or the like. In this embodiment, an I-beam is used. The first pulley mechanism 20 and the second pulley mechanism 14 each include two vertical hangers arranged along the extension direction of the track, with two rollers arranged on both sides of each vertical hanger along the direction of track movement. The first connecting shaft is fixed to the lower end of the vertical hanger of the first pulley mechanism. The lower end of the first connecting shaft is threaded, and two fastening nuts 24 are screwed onto the lower end of the first connecting shaft. The lower end of the vertical hanger of the second pulley mechanism is detachably fixed to the support plate 43 via an L-plate 30 and bolts.
[0038] The second C-shaped steel rail has a detachable section 11, the length of which is greater than the front-to-back length of a structure formed by a vertical hanger plate and rollers on both sides thereof. Fixed plates 23 are welded on both lateral sides of the detachable section 11, and the ends of the fixed plates extend outward from the detachable section in the front-to-back direction. The fixed plates are fixed to the second C-shaped steel rail adjacent to the detachable section by bolts 22.
[0039] The oblong mobile parachute manipulation training simulation device of this embodiment can hang a simulated parachute manipulation training unit 39 with a pulley mechanism on each transverse guide rail. Since there are multiple transverse guide rail units between the inner circle track unit and the outer circle track unit, it can meet the requirements of simultaneous use by squads and even companies. By controlling the operation of the first track walking mechanism of each transverse guide rail unit, each transverse guide rail moves along the inner circle track unit and the outer circle track unit, and the parachutists on the simulated parachute manipulation training unit move along with it, simulating the floating movement in the air caused by the inertia of the parachutists after parachuting, and then the parachutists perform corresponding operations according to the functions of the simulated parachute manipulation training unit.
[0040] Furthermore, the first track walking mechanism includes a driven walking mechanism and an active walking mechanism connected to the driven walking mechanism through a hinged structure. The driven walking mechanism is responsible for lifting the transverse guide rail, and the active walking mechanism is responsible for driving the moving walking mechanism to move. The hinged structure connection can avoid stress and jamming between the active walking mechanism and the driven walking mechanism in the process of passing through the curve. The driven walking mechanism adopts three sleeves to be connected to the corresponding first pulley mechanism and the vertical fixing member respectively, so as to avoid stress damage caused by the lack of synchronization of the first track walking mechanism at both ends of the transverse guide rail and jamming of the first pulley mechanism on the track.
[0041] Furthermore, for the I-shaped guide rail, the walking motor is installed on one side of the roller to drive the roller shaft, which is unstable and often requires a walking motor on each side. In the solution of the present application, the walking motor is placed under the track, and the active walking mechanism is driven to move along the track by rubbing the bottom of the guide rail with a cylindrical driving wheel, thereby pushing the active walking mechanism to move along the track. Since the cylindrical driving wheel is located directly below the track, the operation is smoother and only one walking motor is required. In addition, in order to prevent falling, the airborne simulation training device often prefers C-shaped steel guide rails, and the rollers can be placed inside the C-shaped steel guide rails. Since the internal space of the C-shaped steel guide rails is limited, how to drive the simulated parachute control training unit to move along the guide rails is a difficult problem. The walking motor is placed under the guide rail, and the problem is well solved by rubbing the bottom of the guide rail with a cylindrical driving wheel.
[0042] Furthermore, one side of the base plate of the walking motor is hinged, and the other side is provided with a cylindrical spring seat and a compression spring with adjustable height. The compression spring presses the base plate of the walking motor to press the cylindrical drive wheel of the walking motor against the bottom of the guide rail. Due to the limiting effect of the hinged structure, compared with the spring structure provided at both ends, there will be no shaking in the left and right directions, and it is more stable. The structure of the vertical fixing part is very strong and can meet the requirements of rotation in the connecting tube. The top of the second connecting shaft passes through the corresponding sleeve and the diameter of the stop edge is larger than the inner diameter of the corresponding sleeve, so that the vertical fixing part is hung on the driven walking mechanism through the stop edge. A vertical upper reinforcing plate is fixed between the horizontal hanging plate and the connecting tube, and a vertical lower reinforcing plate is fixed on the transverse guide rail, which further enhances the structural strength of the connection between the vertical fixing part and the transverse guide rail and the structural strength of the vertical fixing part itself.
[0043] Furthermore, the hinged structure includes a first hinge plate fixed to the rear ends of the two vertical plates, a connecting plate fixed to the second pulley mechanism, a second hinge plate fixed to the connecting plate, and a hinge shaft vertically inserted into the first and second hinge plates. Both the inner and outer track units include an upper reinforcement beam and a second C-shaped steel track with a downward-facing opening fixed to the bottom surface of the reinforcement beam. This allows the rollers to be placed within the C-shaped steel rail, effectively preventing them from falling. The upper reinforcement beam enhances the structural strength of the inner and outer track units, reduces the overhang of the strain gauge, and ensures the track's reliability and practicality.
[0044] Furthermore, since the roller-type consumables need to be replaced in a timely manner, the second C-shaped steel track has a detachable section, which can easily remove the vertical hanging plate and the rollers on both sides. Fixed plates are fixed on both sides of the detachable section. The fixed plates are fixed to the second C-shaped steel track adjacent to the detachable section by bolts, realizing the detachable function of the detachable section and strengthening the structural strength of the section, ensuring that after the detachable section is installed, the rollers can safely and smoothly pass through the detachable section. The lower end of the first connecting shaft has a thread, and two fastening nuts are screwed on the lower end of the first connecting shaft, which are used to remove the first connecting shaft and support the parallel vertical plates.
[0045] In other embodiments, the second track traveling mechanism may also adopt the structure of the first track traveling mechanism. In this case, both ends of the transverse track have driving forces, but the operation of the traveling motors of the first track traveling mechanism and the second track traveling mechanism needs to be set. That is, when running on a straight track segment, the first track traveling mechanism and the second track traveling mechanism have the same operating speed. When turning on a semicircular track segment, the first track traveling mechanism and the second track traveling mechanism have the same angular velocity. The linear velocity can be calculated according to the linear velocity formula based on the radius of each semicircular track segment. This setting is a prior art and is very easy to implement, so it will not be elaborated here.
[0046] Regarding power supply, the walking motor can be powered by its own lithium battery unit, or a conductive slot with a conductive bar at the bottom can be set on one side of the outer ring track unit and / or the inner ring track unit, and the walking motor can be connected to a brush that slides in contact with the bottom of the conductive slot to draw power, or the conductive rollers and conductive wires of the tram can be used to draw power. The power-drawing structure and power-drawing method are all existing technologies and will not be elaborated here.
