Description

Technical Field

[0001] The present invention relates to the technical field of rescue equipment, in particular to a narrow space emergency rescue transport device for water environment engineering. Background Art

[0002] Generally, narrow water environments are located in natural drainage channels that are below the ground or displaced below the ground, such as road engineering sewers, wellheads, etc. Since such narrow structures are below the ground, the frequency of exchange between the space and the outside air is low, resulting in less oxygen in the internal space. In addition, due to the presence of gases produced by decaying matter in the space, long-term retention will damage human health and may even lead to coma. Therefore, a device is needed to rescue people who accidentally fall into narrow spaces to assist in the effective implementation of rescue.

[0003] The invention patent with application number CN202221788326.1 discloses a confined space emergency rescue transportation device, including a support rod, a base, a ground nail, a connecting seat, a positioning hole, and a limit plate. The beneficial effects of the utility model are as follows: there are two fixed seats in the device, and a third roller seat is connected to the other fixed seat, and the center of the third roller seat is rotatably connected to the third roller, and the third roller is connected to the second lifting rope, one end of the second lifting rope is fixed to the top of the first roller seat, and the other end is fixed to the top of the second roller seat, and is rotatably connected to the third roller on the second roller seat. The device enables rescue personnel to quickly lift objects for transportation during rescue. A fan-shaped limit plate is welded and fixed at the edge of the connecting seat in the device, and positioning holes are provided at equal angles at the edge of the limiting plate. Locking screws are provided in the positioning holes, so that the staff can adjust the overall support angle of the support rod according to needs, thereby improving the overall stability of the device. However, the overall integrated support structure is adopted, which is inconvenient to store and transport the structure, which increases the space required for transportation. Therefore, an emergency rescue transportation device for narrow space in water environment engineering is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an emergency rescue and transportation device for a narrow space in a water environment engineering project in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an emergency rescue and transportation device for a narrow space in a water environment engineering, comprising a bottom support rod and a rope collecting device, the top end of the bottom support rod is hingedly connected to a connecting support rod, the side of the connecting support rod is fixedly connected to a plug rod fixed end, the inner side of the plug rod fixed end is slidably connected to a latch rod, the top side surface of the plug rod fixed end is fixedly connected to a pin rod spring, the top end of the connecting support rod is hingedly connected to a hinge plate, the top surface of the hinge plate is fixedly connected to a supporting round table, the The outer end of the pressure plate is fixedly connected to the bottom surface of the support rod, and the bottom end of the pressure plate spring is fixedly connected to the fixing ring block, and the fixing ring block is fixedly connected to the fixing ring block. The bottom end of the push rod is fixedly connected. Through the above structure, first, when in use, the bottom support rod is unfolded from the inner side of the connecting support rod around the hinge as a node. During the flipping process of the bottom support rod, the arc surface at the top of the bottom support rod contacts the latch rod, and the latch rod is pushed upward. When the latch rod moves upward, the pin rod spring is pulled. After the connecting support rod and the bottom support rod are kept parallel, the pin rod spring releases the elastic force, allowing the latch rod to move downward and insert into the hole at the top of the bottom support rod for connection, thereby achieving rapid fixation and connecting the connecting support rod around the hinge at the hinge plate. When the node rotates, the snap ring groove opened at the top of the connecting strut gradually fits into contact with the locking ring as it flips. When the supporting table is subjected to downward force, it ensures that the connecting strut and the hinge plate are hinged and no longer rotate. When the contact is locked, the elastic pressure plate is lifted upward, and the elastic pressure plate moves while driving the downward push rod to move. During the movement of the downward push rod, the fixed ring block connected to the end of the downward push rod squeezes the pressure plate spring to produce deformation, and the fixed ring block is moved together with the locking ring until the adjacent retaining ring grooves and the locking ring can clamp the connecting strut.

[0006] The rope collecting device includes a driving support plate, a lifting rod end shell is provided on the front side of the driving support plate, and a handle is fixedly connected to the left side of the lifting rod end shell.

The side surface of the lifting rod end shell is provided with a sliding rod waist groove, the rope winding gear is clamped and connected with the tooth block, and the tooth block is rotatably connected to the lifting rod end shell. The left side of the tooth block Two arc-shaped grooves are provided on the side, and the arc-shaped grooves on the side of the tooth block are matched with the positioning balls. The guide rope roller is rotatably connected to the driving support plate, and the contraction guide block is fixedly connected to the supporting round table. Through the above structure, when in use, the handle is held by hand and lifted from the bottom to the top. When the handle is lifted from the bottom to the top, the lifting rod end shell is driven by the handle to rotate around the rope winding roller shaft. At this time, the internal ball spring of the lifting rod end shell squeezes the positioning balls to be stuck in the groove on the side of the tooth block, and the teeth on the side of the tooth block are engaged with the rope winding gear. At this time, the lifting rod end shell and the rope winding roller When the wheel shaft rotates, and the handle is turned, the tooth block is no longer engaged with the rope winding gear, and the rotation squeezes the locking ball and ball spring. At this time, the lifting rod end shell no longer rotates coaxially with the rope winding roller. At the same time, when the lifting rod end shell rotates downward counterclockwise, it drives the lifting connecting rod to move downward. At this time, the downward pressure spring block connected to the lifting connecting rod pulls the downward pressure spring, and the movement of the downward pressure spring block drives the clamping block lifting rod to move downward, and the rope tightening block outside the clamping block lifting rod is gradually tightened under the guidance of the contraction guide block, and then the rope passing through the rope tightening blocks on both sides is clamped and fixed to prevent the rope on the rope winding roller from moving downward.

[0007] The side of the rope collecting device is provided with a rope locking device, and the rope locking device includes a flip rod, the front side of the flip rod is fixedly connected to a limited stop block, the left top end of the driving support plate is provided with a hook groove, the right side of the driving support plate is fixedly connected with a hook groove block, the surface of the hook groove block is engaged with a hook block suspension rod, the hook block suspension rod passes through the bottom end of the guide rope end, and a suspension rod spring is provided on the outside of the bottom end of the hook block suspension rod, the end of the hook block suspension rod is fixedly connected with a downward pressing lever, and the outer side of the downward pressing lever is slidably connected with two inclined groove slide rods, and the two places The inner side surface of the inclined groove slide bar is provided with a locking support block, and the right bottom surface of the driving support plate is fixedly connected to the lever slide groove, and the side surface of the driving support plate is provided with a lifting rod guide groove running through the two side surfaces, and the lifting rod guide grooves are symmetrically distributed, the flip rod is rotatably connected to the driving support plate, and the left end of the limit stop block is fixedly connected with a hook, and the hook groove is engaged with the hook, and the right end of the limit stop block extends outward, and the hook block suspension rod passes through the bottom surface of the hook groove block, the bottom end of the suspension rod spring is fixedly connected to the downward pressing lever, and the top end of the suspension spring is fixed to the bottom surface of the guide rope end The lifting rod guide groove is slidably connected to the clamping block lifting rod, and the push rod slide groove is slidably connected to the pressing push rod. An inclined slide groove is provided above the lifting rod guide groove, and the inclined slide groove is slidably connected to the inclined groove slide rod. Through the above structure, when the rope located at the upper part of the supporting circular platform breaks, the rope winding roller is no longer dragged by the rope, and the kinetic energy generated by the short rope instantly makes the rope winding roller rotate clockwise. When the rope winding roller rotates, the lifting rod end shell will rotate with it. When the lifting rod end shell exceeds the limit height blocked by the limit block, the lifting rod end shell will rotate When the cam is in motion, the limit block is pushed upward, and the flip rod connected to the limit block is rotated around the hinge point, so that the hook at the end of the flip rod is disengaged from the hook slot, and then the right side extension part of the flip rod pushes the hook block boom in a deflection manner, so that the hook block boom is no longer blocked by the hook slot block. When the boom spring at the bottom side of the hook block boom stores energy, the downward pressure lever connected to the bottom end of the hook block boom will accelerate downward movement, thereby pushing the inclined slot slide rod connected to the downward pressure lever, allowing the inclined slot slide rod to slide along the inclined slot, and then allowing the two inclined slot slide rods to approach quickly, and using the locking support block to clamp the broken rope.

[0008] The end of the connecting strut is provided with a reinforcing device, and the reinforcing device includes a spring-pressing push rod, the outer side surface of the bottom end of the spring-pressing push rod is fixedly connected to an oblique pressure block, the inner side of the bottom end of the connecting strut is hingedly connected to a support pedal, the surface of the support pedal is provided with a rod-penetrating groove, the upper surface of the support pedal is provided with a pressure nail block, the bottom surface of the pressure nail block is fixedly connected to a ground nail, the spring-pressing push rod passes through the interior of the connecting strut, and the spring-pressing push rod is slidably connected to the connecting strut, and the bottom of the pressure nail block The surface forms an angle with the horizontal line, and the angle is less than twenty degrees. The ground nail passes through the bottom surface of the supporting pedal. Through the above structure, when the pin rod is pulled by the pin rod spring with the elastic force released and inserted into the connecting support rod, the pin rod hits the spring-pressing push rod at the moment of inserting into the connecting support rod, causing the spring-pressing push rod to pop out from the connecting support rod and pass through the rod groove and insert into the ground. At the same time, the oblique pressure block on the outside of the spring-pressing push rod will squeeze the pressure nail block, causing the pressure nail block to apply pressure to the ground nail and allow the ground nail to be inserted into the ground, thereby achieving rapid fixation.

[0009] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0010] 1.

When the folding structure is unfolded, the folding structure is quickly locked by rotating or moving the structure, which facilitates the folding and storage of the entire structure while saving the time required for locking and adjusting the structure, thereby improving rescue efficiency.

[0011] 2. This emergency rescue and transportation device for confined spaces in water environment projects uses a lifting connecting rod, a pressing spring, a clamping block lifting rod, a tight rope block, a guide rope end, and a retracting guide block to allow the rod-shaped structure to exert force to reel in the rope, thereby improving the efficiency of rope reeling and reducing the pressure on the side where the hand contacts the rope.

[0013] 4. The emergency rescue and transportation device for narrow spaces in water environment projects uses spring-loaded push rods, inclined pressure blocks, support pedals, rod slots, pressure blocks, and ground nails to allow the elastic structure to impact. The force generated by the impact triggers the operation of other structures, assisting the fixed structure in inserting into the ground, thereby increasing the stability of the entire device when it is fixed on the ground.

Through the above structure, when in use, the handle 53 is held by hand and the handle 53 is lifted from the bottom to the top. When the handle 53 is lifted from the bottom to the top, the lifting rod end shell 52 is driven by the handle 53 to rotate around the rotating shaft of the rope winding roller 58. At this time, the internal ball spring 57 of the lifting rod end shell 52 squeezes the positioning ball 56 and is stuck in the groove on the side of the tooth block 55. The teeth on the side of the tooth block 55 engage with the rope winding gear 54. At this time, the lifting rod end shell 52 and the rope winding roller 58 rotate through the axis. When the handle 53 is rotated, the tooth block 55 is no longer meshed with the rope winding gear 54, and the rotation squeezes the positioning ball 56 and the ball Spring 57, at this time, the lifting rod end shell 52 no longer rotates coaxially with the rope winding roller 58, and at the same time, when the lifting rod end shell 52 rotates downward counterclockwise, it drives the lifting connecting rod 612 to move downward. At this time, the downward pressure spring block 611 connected to the lifting connecting rod 612 pulls the downward pressure spring 613, and the downward pressure spring block 611 moves to drive the clamping block lifting rod 614 to move downward, and allows the rope tightening block 615 outside the clamping block lifting rod 614 to gradually tighten under the guidance of the contraction guide block 617, and then clamps and fixes the rope passing through the rope tightening blocks 615 on both sides to prevent the rope on the rope winding roller 58 from moving downward. The rope winding is achieved by applying force through the rod-shaped structure, which can improve the rope winding efficiency and reduce the pressure on the side of the hand that contacts the rope.

[0024] The side of the rope collecting device 5 is provided with a rope locking device 512, which includes a flip rod 513. The front side of the flip rod 513 is fixedly connected to a limited stopper 514. A hook groove 515 is provided on the top left side of the driving support plate 51. The right side of the driving support plate 51 is fixedly connected to a hook groove block 516. The surface of the hook groove block 516 is engaged with a hook block suspension rod 517.

The lifting rod guide groove 522 is slidably connected to the clamping block lifting rod 614, and the lever slide groove 523 is connected to the downward pressing lever 5 19 sliding connection, an inclined slide groove is provided above the lifting rod guide groove 522, and the inclined slide groove is slidably connected to the inclined groove slide rod 520. Through the above structure, when the rope located on the upper part of the supporting truncated plate 8 breaks, the rope winding roller 58 is no longer dragged by the rope, and the kinetic energy generated by the short rope instantly makes the rope winding roller 58 rotate clockwise. When the rope winding roller 58 rotates, the lifting rod end shell 52 will rotate with it. When the lifting rod end shell 52 exceeds the limit height blocked by the limit block 514, the lifting rod end shell 52 will be pushed up when it rotates, and the flip rod 513 connected to the limit block 514 will be rotated around the hinge point, so that the hook at the end of the flip rod 513 is disengaged from the hook groove 515 , and then the right side extension of the flip rod 513 pushes the hook block suspension rod 517 in a deflection manner, so that the hook block suspension rod 517 is no longer blocked by the hook groove block 516. When the suspension rod spring 518 with energy stored on the bottom side of the hook block suspension rod 517, the downward pressure lever 519 connected to the bottom end of the hook block suspension rod 517 will accelerate downward movement, thereby pushing the inclined groove slide bar 520 connected to the downward pressure lever 519, allowing the inclined groove slide bar 520 to slide along the inclined slide bar, thereby allowing the two inclined groove slide bars 520 to quickly approach each other, and use the locking support block 521 to clamp the broken rope. In the event of an emergency situation in which the rope is suddenly broken, the rope is quickly locked and fixed to prevent the broken rope from falling rapidly and causing rescuers to fall and be injured, thereby improving the safety of the overall device.

[0025] The end of the connecting strut 2 is provided with a reinforcement device 9, which includes a spring-pressing push rod 91. The outer side surface of the bottom end of the spring-pressing push rod 91 is fixedly connected to an oblique pressure block 92. The inner side of the bottom end of the connecting strut 2 is hingedly connected to a support pedal 93. The surface of the support pedal 93 is provided with a rod-penetrating groove 94. The upper surface of the support pedal 93 is provided with a pressure nail block 95. The bottom surface of the pressure nail block 95 is fixedly connected to a ground nail 96. The spring-pressing push rod 91 passes through the interior of the connecting strut 2, and the spring-pressing push rod 91 is slidably connected to the connecting strut 2. The bottom surface of the pressure nail block 95 is at an angle to the horizontal line, and the angle is less than 20 degrees. The ground nail 96 is penetrated by the surface of the support pedal 93. Through the bottom surface, through the above structure, when the pin rod 4 is pulled by the pin rod spring 6 with the elastic force released and inserted into the connecting support rod 2, the pin rod 4 hits the spring push rod 91 at the moment of inserting into the connecting support rod 2, so that the spring push rod 91 pops out from the connecting support rod 2 and passes through the rod groove 94 and is inserted into the ground. At the same time, the oblique pressure block 92 on the outside of the spring push rod 91 will squeeze the pressure nail block 95, so that the pressure nail block 95 puts pressure on the ground nail 96 and allows the ground nail 96 to be inserted into the ground, realizing rapid fixation. The impact is achieved through the elastic structure, and the force generated by the impact triggers the operation of other structures to assist the fixing structure to be inserted into the ground, thereby increasing the stability of the overall device when fixing the ground.

[0026] Working principle: First, when in use, the bottom support rod 1 is unfolded from the inner side of the connecting support rod 2 around the hinge as a node. During the flipping process of the bottom support rod 1, the top arc surface of the bottom support rod 1 contacts the latch rod 4 and pushes the latch rod 4 upward. When the latch rod 4 moves upward, it pulls the pin rod spring 6. After the connecting support rod 2 and the bottom support rod 1 remain parallel, the pin rod spring 6 releases the elastic force, allowing the latch rod 4 to move downward and insert into the hole at the top of the bottom support rod 1 for connection;

[0027] When the latch rod 4 is pulled by the released pin rod spring 6 and inserted into the connecting support rod 2, the latch rod 4 hits the spring push rod 91 at the moment of insertion into the connecting support rod 2, causing the spring push rod 91 to pop out of the connecting support rod 2 and pass through the rod penetration groove 94 and penetrate into the ground. At the same time, the oblique pressure block 92 on the outer side of the spring push rod 91 squeezes the pressure nail block 95, causing the pressure nail block 95 to apply pressure to the ground nail 96, and the ground nail 96 is penetrated into the ground.

[0028] The rope of the rope roller 58 is lowered, and after the rescuer has fixed the rope, he holds the handle 53 with his hand and lifts the handle 53 from bottom to top, driving the lifting rod end shell 52 to rotate around the rope roller 58 shaft through the handle 53. At this time, the internal ball spring 57 of the lifting rod end shell 52 squeezes the positioning ball 56 and is stuck in the groove on the side of the tooth block 55. The teeth on the side of the tooth block 55 engage with the rope winding gear 54. At this time, the lifting rod end shell 52 and the rope winding roller 58 rotate through the axis. When the handle 53 is turned, the tooth block 55 is no longer bonded to the rope winding gear 54, and the rotation squeezes the positioning ball 56. The ball 56 and the ball spring 57, at this time, the lifting rod end shell 52 no longer rotates coaxially with the rope winding roller 58, and at the same time, when the lifting rod end shell 52 rotates downward counterclockwise, it drives the lifting connecting rod 612 to move downward. At this time, the downward pressure spring block 611 connected to the lifting connecting rod 612 pulls the downward pressure spring 613, and the downward pressure spring block 611 moves to drive the clamping block lifting rod 614 to move downward, and allows the tightening rope block 615 outside the clamping block lifting rod 614 to gradually tighten under the guidance of the contraction guide block 617, and then clamps and fixes the rope passing through the tightening rope blocks 615 on both sides, repeats the above steps, and the rope can be wound up.
