Description

Technical Field

[0001] The invention relates to the technical field of climate environment testing, and in particular to a launching test system for a suspended launching device under a temperature shock environment. Background Art

[0002] The suspended launch device uses the aircraft as a platform and launches weapons and ammunition with destructive and lethal effects to targets on the ground or in the air through an airborne launch system. In the process of performing missions, the aircraft is affected by the atmospheric temperature gradient, geographical environment, time factors, meteorological conditions and mission requirements, and thus encounters various temperature environments. In particular, when the aircraft is rapidly climbing or descending, the rapid altitude change can cause drastic temperature fluctuations in just tens of seconds, causing the aircraft to be instantly affected by the temperature shock environment. The suspended launch device is affected by factors such as thermal expansion and contraction, lubrication characteristics and changes in material properties under different temperature environments, which can cause the delivery function to fail or the delivery accuracy to decrease, thereby affecting the reliability and safety of the entire system. Therefore, the delivery reliability assessment in a rapid temperature change environment is of great significance to the safety of the aircraft.

[0003] There are two existing methods for the release test of suspended launchers in a temperature shock environment. One is to install the release system of the suspended launcher in a large temperature shock test chamber to directly conduct the release test assessment. The other is to use the two-chamber method, prepare two temperature test chambers that are close to each other, install the release system of the suspended launcher in one of the large temperature test chambers to complete the release test assessment, and then switch to the other large temperature test chamber within 1 minute to complete the release test assessment. However, there are the following problems with the above two methods: (1) The release test of the suspended launcher has requirements on the size of the temperature shock test chamber, and the existing large test chambers are limited in size and cannot meet the release assessment requirements of various types of launchers and large-sized simulated bombs; (2) The large temperature shock test chamber has requirements for rapid temperature change capability, and the existing technology is limited and it is difficult to meet the test requirements of national military standards; (3) The two-chamber method has requirements for conversion time, and the manual disassembly of the test piece and then conversion cannot meet the assessment requirements of the conversion time of the temperature shock test. Summary of the invention

[0004] The purpose of the present invention is to provide a release test system for a suspended launch device in a temperature shock environment. The suspended launch device can be transferred within 1 minute through a movable rack release device, thereby realizing the release test assessment in a temperature shock environment.

[0005] When conducting a drop test assessment on a suspended launch device under a temperature shock environment, the following requirements are imposed on the test system: (1) It must be able to provide a climatic environment for the suspended launch device in accordance with the test requirements, and must be able to transfer the suspended launch device within 1 minute; (2) It must have the functions of hoisting, safety, and linkage coordination, and must be able to quickly recover and transport the test piece; (3) The drop frame must meet the corresponding load-bearing requirements, and must have the characteristics of simple structure, efficient construction, and safety assurance; (4) It must be able to realistically simulate the installation boundary of the suspended launch device on the aircraft, and must be able to provide the functions of fixed-point drop, free and rapid transfer, and stable suspension for simulated missiles; (5) It must be able to reliably lock the suspended launch device at the drop point, and must be able to safely limit the position of the movable rack drop device; (6) The drop buffer recovery trough must be simple to install, easy to use, reusable, safe, and reliable, and must be able to recover the simulated missiles by vertical drop and rotation drop, and must be able to vertically transport the simulated missiles in the buffer trough and drop them at a specified height to achieve simulated drop at different heights; To achieve the above purpose, the technical solution provided by the present invention is as follows: The present invention provides a delivery test system for a suspended launch device under a temperature shock environment, comprising a walk-in test box, a delivery frame, a movable rack delivery device, a locking device, a limit protection device, a transfer vehicle, and a delivery buffer recovery tank, wherein: The walk-in test chamber is used to simulate test environments such as temperature, humidity, and damp heat. Two walk-in test chambers are used in conjunction with a movable rack launch device to realize the launch test assessment of the suspended launch device in a temperature shock environment.

[0006] The delivery frame is used to provide stable structural support to withstand the reaction force generated by the simulated projectile ejection and the supporting force of the electric hoist.

[0007] The movable rack delivery device is composed of a suspension system, a mounting platform, a motion system, and a delivery point. It is used in conjunction with a delivery buffer recovery trough to realize the installation, transfer, and delivery functions of the suspended launch device.

[0008] The locking device is used to fix the actuator piston rod to prevent the piston rod from falling due to failure of the hydraulic system.

[0009] The limit protection device adopts the dual protection design of soft limit and hard limit to prevent the moving installation platform from over-displacing after reaching the release point.

[0010] The transfer cart is installed on a fixed guide rail and is moved by pulleys configured under the transfer cart. It is used to realize the transfer of simulated bullets inside and outside the walk-in test box and between each other.

[0011] The release buffer recovery trough is located at the bottom of the test box. The buffer trough is arranged with high-strength buffer materials and is equipped with a lift to simulate the release and recovery of missiles and realize the function of simulated release at different heights.

[0012] Among them, the walk-in test box includes 1# walk-in test box and 2# walk-in test box, and the 1# walk-in test box and 2# walk-in test box both include a cabin structure, left and right electric double-opening sliding doors, a test box observation window, manual side doors, a detachable cover, a guardrail, a manual sliding door, and a supporting system; wherein, the cabin doors of the 1# walk-in test box and the 2# walk-in test box are facing each other and are symmetrically installed on the test bearing foundation. The front of the test box cabin is provided with left and right electric double-opening sliding doors, the side of the test box cabin is provided with manual side doors and observation windows, a manual sliding door is arranged at the central opening position of the cabin top plate, and guardrails are arranged around it. A delivery buffer recovery trough is opened at the center position of the bottom plate of the test box cabin, and a detachable cover is installed above the top of the trough.

[0013] It should be noted that the effective internal dimensions of the cabin structure are 5m deep × 3m wide × 3m high, and the volume of the test chamber is greater than 45m 3The cabins all adopt modular sandwich insulation panel assembly structure. The sandwich panels are made of outer color steel plate + high-density rigid polyurethane (PU) foam + inner stainless steel plate to ensure the sealing, thermal insulation, stability and bearing capacity of the cabin structure. 125×125H steel is laid inside the roof area of ​​the warehouse and insulated with epoxy resin board to achieve the high load requirement of 100kN. Secondly, an 800mm×1000mm hole is opened in the center of the roof, and a manual sliding door is configured to enable on-site crane to lift the test piece. The front of the test box cabin is a 2.4m wide × 3m high left and right electric double-opening sliding door, which moves in an upper hanging guide rail mode and is equipped with a 3kw reduction motor to provide transmission power. The door is driven to move smoothly along the guide rail through the transmission rack, and the door opening degree can be linked with the movable rack delivery device. According to the size requirements of the suspended launch device and the simulated bomb, the cabin structure can be modularly assembled, with the characteristics of simple structure, efficient construction, simple operation and high flexibility. The observation window of the test chamber is 0.4m wide × 0.6m high. It adopts multi-layer vacuum insulation glass, and the inner and outer coatings are electrically heated to prevent frost, which can effectively ensure airtightness, heat insulation, sound insulation, firm structure and no deformation. Ensure that the glass surface does not condense or frost during the low temperature and humidity test in the cabin and remains transparent to ensure normal observation. The effective size of the manual side door is 0.8m wide × 2m high. It adopts a single hinged door. The door material is consistent with the cabin material to ensure the sealing and thermal insulation performance of the cabin door. The guardrail is used as a safety protection for the test personnel to climb up, which can effectively prevent people from falling from heights and ensure personal safety. The supporting system consists of an air circulation system, a refrigeration system, a heating system, a humidification and dehumidification system, and an electrical and control system. By adopting the automation electrical appliances and control system with PLC as the core, the coordinated operation of the air circulation system, refrigeration system, heating system, humidification and dehumidification system can be realized to achieve the goals of equipment temperature and humidity adjustment, high and low temperature environment setting, relative humidity change, etc., and through remote / local control, monitoring detection, and safety alarm functions, it is possible to set experimental parameters such as program curves and working time, display the operating status of the entire equipment, display data and curves such as temperature and humidity in real time, generate real-time data reports, and save them regularly. When a fault occurs during the operation process, it can automatically alarm, and display the corresponding alarm information on the human-machine interface. Major faults have an automatic power-off function. The performance of a single box can meet the temperature range of -60℃~+150℃, the temperature change rate of ≥3℃ / min, and the relative humidity of 20%~98%RH. The performance of the double box combination can achieve a temperature shock range of -55℃~+70℃, a temperature change rate of ≥3℃ / min, and a conversion time of ≤1min.

[0014] Among them, the launching frame includes a base plate, columns, beams and a mounting base; the columns are welded to the base plate, the base plate is installed on the test bearing foundation, the beams are welded to form the launching frame, the mounting base is configured on the side, and the motion system is cooperated to realize the steering of the guide pulley.

[0015] It should be noted that the delivery frame is composed of a base plate, columns, beams, and mounting bases, all of which are 300mm×300mm×25mm large-diameter thick-walled square tube steels, which are standard model products manufactured by mechanical processing. The base plate is welded to form a stable and reliable connection with the test bearing foundation through bolts, and then square tube steels of different specifications are spliced ​​together in sequence through welding to form a delivery frame, which can withstand a delivery reaction force of 100kN, thereby ensuring the stability and bearing capacity of the entire test system. At the same time, a mounting base is configured on the side to cooperate with the motion system to realize pulley guidance. According to the size requirements of the test box, the structural shape of the delivery frame can be modularly designed, which greatly improves the flexibility of building the delivery frame. It has the characteristics of simple structure, efficient construction, reusability and safety assurance, and can effectively improve the test efficiency.

[0016] The movable rack delivery device includes a suspension system, a motion installation platform, a motion system, and a 1# delivery point and a 2# delivery point; Among them, the 1# delivery point and the 2# delivery point are both supported by the beam of the delivery frame, and the upper support plate and the lower support plate are fixed on the beam, and the hydraulic actuator above the upper support plate and the locking device above the lower support plate are fixed in sequence to form the 1# delivery point and the 2# delivery point; the motion installation platform is respectively connected to the locking block and the suspension launching device, and multiple groups of sliders on both sides of the motion installation platform enable it to move freely on the 1# motion guide rail, the 2# motion guide rail, and the 3# motion guide rail. The 1# track fracture and the 2# track fracture are respectively set at the hatch of the test box cabin; an adjusting rod is installed at the front end of the motion installation platform to connect the wire rope, which is input through the host computer of the motion system and controlled by the PLC controller to pull the winch to the specified position.

[0017] The suspension system is composed of multiple suspension launcher installation sliders. The upper part of the installation slider is a T-shaped structure, and the lower part is a double-ear structure. It can be connected with different types of suspension launchers through bolts, which can accurately simulate the installation boundary of the suspension launcher on the aircraft. The installation slider can move in the T-shaped installation slot of the installation platform to adjust the fixed position of the suspension system on the installation platform. The installation platform is divided into a motion installation platform and a fixed installation platform. The motion installation platform is used for the release test under the temperature shock environment. The upper surface is equipped with a T-shaped locking slot, and the lower surface is equipped with a T-shaped installation slot, which is used for locking the installation platform and installing the suspension launcher, respectively, to meet the stability and reliability requirements of the assembly of different types of suspension launchers; the fixed installation platform is used for fixed point release test, and the upper and lower surface configurations are consistent with the motion installation platform. Before use, the motion installation platform is first removed, and then the fixed installation platform is installed on the load-bearing frame outside the test box through screws, so that the release test of the suspension launcher under normal temperature, high and low temperature, and humid and hot environments can be realized. The motion system consists of a motion guide rail, an adjustment rod, a winch, a PLC controller, a guide pulley, a compensation device, a laser displacement sensor, and a follow-up reflector end. Multiple slider mounting seats are configured on the side of the motion installation platform, which can realize the sliding of the motion installation platform on the slider track. Threaded adjustment rods are installed at both ends of the motion installation platform to connect the wire rope, and the wire rope is connected to the winch through the fixed pulley guide. The winch provides traction power, not only with automatic and manual control, but also can realize linear reciprocating motion conversion. At the same time, a compensation device is configured, which can not only limit the effective torque in both directions to achieve long-term load, but also limit different torques in both directions to achieve overload protection. The automatic control mode of the winch is based on PLC control. The travel distance is set by the host computer, and the laser displacement sensor emits a laser signal, which is reflected by the follow-up reflector end and then received by the laser displacement sensor. The displacement signal is converted into an electrical signal through the displacement measuring instrument and transmitted to the PLC controller, and then the control signal is transmitted to the winch through the distribution cabinet, thereby realizing the measurement and control of the travel distance. In manual mode, the winch is controlled by the manual operation handle to drive the motion installation platform forward and backward on the slider track. The delivery point is supported by the beam of the delivery frame, and is equipped with an upper support plate and a lower support plate, which are used to fix the upper hydraulic actuator and the lower locking device respectively. After reaching the designated position, the hydraulic actuator is controlled to lift the locking block, driving the entire motion installation platform to move vertically upward and away from the motion guide rail until it is in close contact with the bottom surface of the lower support plate, thereby achieving the locking of the motion installation platform, which can not only prevent the reaction force of the missile from impacting the slider track during delivery, but also provide sufficient support stiffness for the suspension system. After the delivery is completed, the hydraulic actuator is controlled to push down the locking block, and the motion installation platform can be slowly lowered onto the motion guide rail.

[0018] Among them, the limit protection device includes a hard limit device and a soft limit device; the hard limit device is installed at the end of the 1# moving guide rail and the 3# moving guide rail, and the soft limit is sensed by the position sensor to the output switch signal of the moving installation platform, and the feedback switch signal is converted into an electrical signal through the position measuring instrument and input into the PLC controller to control the winch to slowly stop.

[0019] It should be noted that the soft limit is achieved by installing a position sensor on the track corresponding to the test target position of the motion installation platform. When the motion installation platform reaches the limit position, the sensor senses the motion installation platform output switch signal, and the feedback switch signal is converted into an electrical signal through the position measuring instrument and input into the PLC controller to control the winch to stop slowly, so that the installation platform can be stopped at the specified position. The hard limit device installs a hydraulic buffer at the end of the track corresponding to the design limit position of the motion installation platform, and the front end of the impact head is a rubber buffer material. When the soft limit fails, the hard limit device can still stop the motion installation platform at the specified position through the buffering and energy absorption characteristics of the hydraulic buffer, effectively preventing hard collisions from causing damage to the mechanism.

[0020] Among them, the transfer vehicle includes a load-bearing frame, a stop beam, a handle, a pulley, a ground rail, and a positioning foot cup; the transfer vehicle moves on the ground rail through the pulley, and a detachable stop beam and a detachable handle are installed on both sides of the transfer vehicle, and a positioning foot cup is arranged on each side of the transfer vehicle.

[0021] It should be noted that the load-bearing frame is welded with 60mm×60mm×3mm square tube steel, and a 5mm thick steel plate is welded at the bottom to enhance its bearing capacity and stability, which can meet the requirement that a single transfer vehicle bears a load of not less than 2000KG. Since the simulated bullets are all round in shape and easy to roll off, removable beams are configured on both sides of the transfer vehicle. The specifications of the beams can be customized according to the diameter of the simulated bullet to ensure the safety and stability of the transfer vehicle during use. At the same time, removable handles are installed on both sides of the transfer vehicle, which have a simple and reliable structure and are easy to use, which is conducive to the test personnel pushing the transfer vehicle to move. The transfer vehicle is equipped with pulleys at the bottom, and tracks are laid in the walk-in test box and between the two walk-in test boxes. The transfer vehicle can walk on the tracks to realize the transfer of products inside and outside the two walk-in test boxes and to transfer each other. A positioning foot cup is configured on each side of the transfer vehicle to facilitate the fixation of the transfer vehicle according to the usage. A convenient handwheel is installed above each positioning foot cup for easy screwing and fixing.

[0022] Among them, the delivery buffer recovery trough includes an electric sliding door panel, a buffer pad, and a lift; an electric sliding door panel is installed above the delivery buffer recovery trough, and a fixed hydraulic lift is installed at the bottom, and a high-density low-rebound buffer pad is laid around the delivery buffer recovery trough and above the lift platform.

[0023] It should be noted that a buffer groove of not less than 1.2m wide and 4m long is reserved in the middle area of ​​the bottom plate of the walk-in test chamber. The buffer groove is equipped with an electric sliding door panel with a thickness of not less than 100mm, which has the function of automatic door opening and closing. The inner layer of the door panel is insulated with high-density polyurethane foam material to ensure the thermal insulation function of the door panel. There is a height difference of 300mm between the bottom plate sliding door and the bottom plate of the warehouse. A number of removable cover plates weighing about 30kg each are arranged at the center slot of the warehouse bottom plate, which not only provides a safe working platform for test personnel to walk on the bottom plate of the warehouse, but also greatly facilitates operations and construction activities in the warehouse. In addition, the manual removal process of the cover plate is also extremely convenient and quick. The entire removable cover plate area can meet the load-bearing requirements of 400KG, and can realize about 6 people standing on the cover plate to carry out construction operations and other activities, which significantly improves the stability and safety of the operation. The buffer tank is equipped with high-strength buffer material, which uses high-density foam sponge. It can withstand the impact of a 1500kg simulant falling at an initial velocity of 5m / s and a height of 4m under gravity acceleration after being buffered by the buffer pad. The material has excellent energy absorption and low resilience. When impacted by the simulated bomb release, it can effectively reduce the secondary bounce height and quickly restore the simulated bomb to a static state, thereby protecting the simulated bomb and the test device. The lift is an indoor fixed hydraulic lift, which can realize the vertical transportation and designated height release of the simulated bomb in the buffer tank. It adopts a scissor lift structure and an electric hydraulic system, which makes it have high bearing capacity, stability and safety. The lift has self-locking and remote control functions. It can not only automatically lock the position during the operation, but also the operator can control the lifting and lowering action of the equipment through the remote control within a certain range, improving the safety and convenience of the operation. At the same time, it is also equipped with an anti-collision device and a one-button emergency stop switch, which can not only effectively prevent the collision with surrounding obstacles during the operation, but also improve the safety of the operation. It can also be shut down immediately in the event of emergency situations such as mechanical failure and personnel injury during the operation to ensure the safety of equipment and personnel.

[0024] The locking device includes an annular piston, a hydraulic chamber, an oil filling nozzle, a chassis, a sleeve, a hollow plunger rod, a disc spring, a clamping ring, and a clamping sleeve; an oil medium is injected into the hydraulic chamber from the oil filling nozzle through an oil pump, and the clamping ring is lifted up by pressure, which compresses the disc spring to elastically deform, thereby releasing the clamping sleeve so that the actuator piston rod can move freely up and down; after the oil is released by the oil pump, the disc spring releases its elastic potential energy and rebounds to act on the clamping ring, thereby squeezing the clamping sleeve and clamping the actuator piston rod in place.

[0025] It should be noted that the annular piston can ensure the air tightness between the hydraulic chamber and the disc spring chamber, effectively prevent mutual penetration between the chambers, and ensure the safe and reliable operation of the locking device. The hydraulic oil is injected into the hydraulic chamber from the oil filling nozzle through the oil pump, and the clamping ring is lifted up by pressure, which compresses the disc spring to elastically deform, thereby releasing the clamping sleeve, so that the actuator piston rod can move freely up and down. After the oil is released by the oil pump, the disc spring releases its elastic potential energy and rebounds to act on the clamping ring, thereby squeezing the clamping sleeve and clamping the actuator piston rod in place, which can effectively prevent the piston rod from falling due to failure of the hydraulic system.

[0026] Compared with the prior art, the present invention has the following beneficial effects: The present application designs a delivery test system for a suspended launch device in a temperature shock environment, which can not only impose climatic environmental conditions on the suspended launch device and complete the transfer within 1 minute, but also can deliver simulated missiles at fixed points, freely and quickly transfer, and stably suspend them. It has the functions of installation-transfer-delivery of simulated missiles, rapid temperature and humidity shocks, safe transfer, and recovery, which solves the size limitations of various types of launch devices and large-size simulated missile delivery, and can realize the delivery assessment of suspended launch devices in conventional, climatic and temperature shock environments.

[0027] The walk-in test chamber of the test system can achieve the goals of equipment temperature and humidity adjustment, high and low temperature environment setting, relative humidity change, etc., and provide climatic environmental conditions for the suspended launch device. A hole is opened in the center of the top plate of the test chamber cabin structure, and a manual sliding door is configured to enable on-site cranes to lift the test piece; the front door of the test chamber cabin structure is a left and right electric double-opening sliding door, which is moved by an upper hanging guide rail, and the door opening degree can be coordinated with the movable rack delivery device; a buffer groove is opened in the middle area of ​​the bottom plate of the test chamber cabin structure, and a detachable cover is configured to meet the 400KG load-bearing requirements, which is convenient for warehouse operations and construction activities. The delivery frame can withstand a delivery reaction force of 100kN. According to the size requirements of the test chamber, the structural shape of the delivery frame can be modularly designed to improve the flexibility of building the delivery frame to meet the load-bearing and size requirements of various types of suspended launch devices. The movable rack delivery device can meet the requirements of transferring the suspension launch device within 1 minute. It can not only truly simulate the installation boundary of the suspension launch device on the aircraft, but also meet the fixed-point delivery of simulated missiles, free and rapid transfer, and stable suspension functions to meet the installation requirements of different types of suspension launch devices. The locking device can meet the reliable locking of the suspension launch device at the delivery point, effectively preventing the piston rod from falling due to failure of the hydraulic system. The limit protection device can provide safety protection for the movable rack delivery device through two protection modes, soft limit and hard limit, effectively preventing damage to the mechanism caused by hard collision. The transfer vehicle can meet the load-bearing requirements of not less than 2000KG, and can realize the transfer of simulated missiles inside and outside the walk-in test box and between each other, and realize the manual brake function through the positioning foot cup. A fixed hydraulic lift is used at the bottom of the buffer recovery trough, which can realize the vertical transportation of the simulated missile in the buffer trough and the release at a specified height. High-density, low-rebound foam sponge is laid around the buffer trough and above the lift platform to meet the recovery requirements of vertical and rotational release of the simulated missile. It can effectively protect the simulated missile and the test device, and ensure the safety of the test process to the greatest extent, so as to realize the accuracy assessment of the release of the suspended launch device under temperature shock conditions.

At the same time, a mounting base 32 is arranged on the side to cooperate with the motion system 67 to realize the steering of the guide pulley 16.

[0039] The 1# delivery point 19 and the 2# delivery point 30 are both supported by the beam 28 of the delivery frame 66. The upper support plate 36 and the lower support plate 37 are fixed to the beam 28 by bolts, which are used to fix the upper hydraulic actuator 22 and the lower locking device 21 respectively. They are connected to the locking block and the suspension launch device 6 through the T-shaped locking groove above and the T-shaped installation groove below the motion installation platform 20. Multiple sets of sliders are installed on both sides of the motion installation platform 20, which can move freely on the guide rails.

At this time, the locking device 21 injects oil medium 39 into the hydraulic chamber 40 from the oil injection nozzle 38 through the oil pump, pressurizes the clamping ring 45, and compresses the disc spring 44 to elastically deform, thereby releasing the clamping sleeve 41. The locking block is lifted by the hydraulic actuator 22, driving the moving installation platform 20 to move vertically upward and disengage from the 3# moving track 27 until it is in close contact with the bottom surface of the lower support plate 35. Then, the oil pump of the locking device 21 is controlled to release the pressure and unload the oil, and the disc spring 44 releases the elastic potential energy to rebound and act on the clamping ring 45, thereby squeezing the clamping sleeve 41 and clamping the hydraulic actuator piston rod 43 in place.

All components are standard model products manufactured by mechanical processing. The structural shape of the delivery frame 66 can be modularly designed according to the size requirements of the test box to meet the load and size requirements of various types of suspended launch devices 6 and simulated bombs 7.

[0041] The motion system 67 and the soft limit 68 are both based on the PLC controller 54. In the automatic control mode of the motion system 67, the laser displacement sensor 59 emits a laser signal, which is reflected by the follower reflector 62 and then received by the laser displacement sensor 59. The displacement signal is converted into an electrical signal through the displacement measuring instrument 57 and transmitted to the PLC controller 54, and then the control signal is transmitted to the winch 17 through the power distribution cabinet 58. The soft limit 68 senses the output switch signal of the motion installation platform 20 by the position sensor 56, and converts the feedback switch signal into an electrical signal through the position measuring instrument 60 and inputs it into the PLC controller 54, so as to control the winch 17 to stop slowly.

The mounting slide block can be moved in the T-shaped mounting groove of the mounting platform to adjust the fixed position of the suspension system on the mounting platform, and can be connected with different types of suspension launch devices 6 by bolts, and can accurately simulate the installation boundary of the suspension launch device 6 on the aircraft. The mounting platform is divided into a motion installation platform 20 and a fixed installation platform 64. The T-shaped locking groove on the upper surface of the motion installation platform 20 can be connected with the locking block, and the T-shaped mounting groove on the lower surface can be connected with the suspension launch device 6, which is used for delivery tests under temperature shock environments; the fixed installation platform 63 is used for fixed point delivery tests. Before use, the motion installation platform 20 is first removed, and then the fixed installation platform 63 is installed on the delivery frame 66 outside the test box by screws, so that the delivery test of the suspension launch device 6 under normal temperature, high and low temperature, and humid and hot environments can be realized.

When the motion installation platform 20 moves to the door of the 1# walk-in test box 5, the left and right electric double-opening sliding doors 8 are controlled to be opened, and the width is slightly larger than the maximum width of the suspension launch device 6, the simulation bomb 7 and the motion installation platform 20, so that the three can enter the 2# walk-in test box 15 from the 1# walk-in test box 5.

[0045] The 1# delivery point 19 and the 2# delivery point 30 are supported by the beam 28 of the delivery frame 66, and the upper support plate 36 and the lower support plate 37 are fixed on the beam 28, and the hydraulic actuator 22 above the upper support plate 36 and the locking device 21 above the lower support plate 37 are fixed in sequence. After reaching the designated position, the hydraulic actuator 22 is controlled to lift the locking block, and the moving installation platform 20 is driven to move vertically upward and away from the moving guide rail until it is tightly attached to the bottom surface of the lower support plate 37, thereby realizing the locking of the moving installation platform 20. After the delivery is completed, the hydraulic actuator 22 is controlled to push down the locking block, and the moving installation platform 20 can be slowly dropped onto the moving guide rail.

[0046] The limit protection device is composed of a soft limit 68 and a hard limit device 31. By installing the hard limit device 31 at the ends of the 1# motion guide rail 23 and the 3# motion guide rail 27, when the soft limit 68 fails, the hard limit device 31 can still stop the motion installation platform 20 at the specified position through the buffering and energy absorption characteristics of the hydraulic buffer; the soft limit 68 senses the output switch signal of the motion installation platform 20 by the position sensor 56, and converts the feedback switch signal into an electrical signal through the position measuring instrument 60 and inputs it into the PLC controller 54, so as to control the winch 17 to stop slowly.

[0047] The delivery buffer recovery trough 2 is composed of an electric sliding door panel 14, a buffer pad 3, and an elevator 4. The electric sliding door panel 14 is installed above the delivery buffer recovery trough 2, and a fixed hydraulic elevator 4 is installed at the bottom, which can realize the vertical transportation and designated height delivery of the simulated projectile 7 in the delivery buffer recovery trough 2. High-density low-rebound buffer pads 3 are laid around the delivery buffer recovery trough 2 and above the elevator 4 platform to meet the recovery requirements of vertical delivery and rotation delivery of the simulated projectile 7.

The transfer vehicle 10 stops on the ground rail 9 between the 1# walk-in test box 5 and the 2# walk-in test box 15, and the transfer vehicle 10 is fixed by screwing the hand wheel of the positioning foot cup 49. The suspension launch device 6 is hoisted onto the transfer vehicle 10 by the overhead crane, and the detachable stop beams 52 on both sides of the transfer vehicle 10 can effectively prevent the simulated bomb 7 from rolling down. The transfer vehicle 10 is pushed along the ground rail 9 to the bottom of the motion installation platform 20 of the 1# delivery point 19 by the detachable handles 50 on both sides of the transfer vehicle 10.

[0049] 2. By controlling the oil pump of the locking device 21, the oil medium 39 is injected from the oil injection nozzle 38 into the hydraulic chamber 40, and the clamping ring 45 is lifted up by pressure, and the disc spring 44 is pressed to elastically deform, thereby releasing the clamping sleeve 41. The locking block is lifted by the hydraulic actuator 22, driving the moving installation platform 20 to move vertically upward as a whole and disengage from the 1# moving track 23 until it is in close contact with the bottom surface of the lower support plate 35. Then, by controlling the oil pump of the locking device 21 to release the pressure and unload the oil, the disc spring 44 releases the elastic potential energy to rebound and act on the clamping ring 45, thereby squeezing the clamping sleeve 41 and clamping the hydraulic actuator piston rod 43 in place.
