Technical Field

[0001] The invention belongs to the technical field of crane pipe auxiliary tools, and in particular relates to an exhaust gas collecting device which also serves as a sleeve and is used for a telescopic loading crane pipe. Background Art

[0002] The crane sleeve is an important component of the crane system. It is mainly used to support and guide the movement of the crane to ensure safe and smooth operation when loading and unloading liquid materials (such as petroleum, chemical products, etc.).

[0003] At present, there is a loading crane pipe on the market with a publication number of CN217323368U, which includes an outer tube, an inner tube and an elastic component. The inner tube and the outer tube are coaxially arranged, and at least one through hole is arranged on the other end of the inner tube; the elastic component includes an elastic member and a baffle, one end of the elastic member is fixedly connected to one end of the outer tube, the other end of the elastic member is movably connected to the baffle, and the other end of the inner tube is fixedly connected to the baffle, and the baffle realizes opening and closing of the port of the inner tube; the advantage is that an inner tube is added inside the outer tube. Since the inner tube is added on the basis of the original outer tube, the inner tube and the outer tube are connected by an elastic member, the inner tube can be freely extended and retracted, and is suitable for tank trucks of different heights.

[0004] The crane pipe anti-drip oil device with the public number CN207030942U comprises a retractable crane pipe vertical pipe, a sealing cover plate is arranged at the upper end of the crane pipe vertical pipe, an oil distributor is arranged at the lower end of the crane pipe vertical pipe, the oil distributor is connected to a driving mechanism via a driving rope, an oil distributor is provided on the side wall of the oil distributor, an elastic diaphragm is arranged inside the oil distributor and below the oil distributor, a sealing assembly and a locking tongue are arranged on the side wall of the oil distributor, the locking tongue is connected to a connecting rod mechanism, the connecting rod mechanism is located below the elastic diaphragm, an outer sleeve is provided on the outer side of the oil distributor, the upper end of the oil distributor is connected to the outer sleeve via a first spring, a groove that can be engaged with the locking tongue is arranged on the inner wall of the lower end of the outer sleeve, the lower end of the oil distributor is connected to an oil receiving head via a second spring, and the lower end of the outer sleeve can be engaged with the inner part of the upper end of the oil receiving head. The beneficial effects of the utility model are as follows: at the end of the loading operation, it can automatically act to prevent oil dripping, and can conveniently and quickly realize automatic receiving of dripping oil.

[0005] But there is also a problem: when the crane pipe is transmitting oil, some of the oil will evaporate and spread in the air, easily causing poisoning to the workers. Summary of the invention

[0006] This solution provides an exhaust gas collection device that also serves as a sleeve for a telescopic loading crane pipe, which is used to solve the problem of workers being poisoned by exhaust gas generated during the transmission process.

[0007] The present invention provides an exhaust gas collection device which also serves as a sleeve for a telescopic loading crane pipe, comprising a sleeve: used to be sleeved on the outer periphery of the crane pipe, the sleeve and the crane pipe being matched; Sealing cover: used to cover the oil tank, the sealing cover matches the oil tank; Telescopic mechanism: used for moving the sleeve, the telescopic mechanism cooperates with the sleeve; Also includes: Collection box: used to collect exhaust gas; Air pipe: one end of the air pipe is connected to the sealing cover, and the other end is connected to the collection box.

[0008] The principle of this solution is that the sleeve is placed around the outer periphery of the crane pipe, and then the position of the sleeve is adjusted so that the sealing cover covers the oil tank. When the crane pipe starts to deliver oil to the oil tank, the liquid flows into the oil tank quickly, causing the pressure in the oil tank to increase. As the liquid enters the oil tank, the original gas (including air and possible oil-gas mixture) is squeezed out. At this time, the gas in the sealing cover is guided to the collection box through the air pipe instead of being released directly into the environment. The collection box receives and treats these exhaust gases through appropriate methods, such as adsorption, condensation or other purification technologies to reduce the emission of harmful substances.

[0009] The beneficial effects of this solution are: 1. The sleeve ensures that the crane pipe maintains the correct posture during loading and unloading and moves along the predetermined path. 2. The design of the sealing cover and the collection box effectively reduces the emission of harmful gases such as VOCs, meeting strict environmental protection standards. 3. The risk of fire or explosion caused by leakage of oil and gas mixture is prevented, improving the safety of operation.

[0010] Furthermore, the telescopic mechanism includes a winch, a steel cable and a lifting lug, the lifting lug is fixedly connected to the sleeve, the sleeve is slidably connected to the crane pipe, one end of the steel cable is fixedly connected to the lifting lug, and the other end is fixedly connected to the winch.

[0011] Slide the sleeve around the outer periphery of the crane tube and ensure that the lifting lug is firmly fixed to the sleeve. One end of the steel cable is fixed to the lifting lug and the other end is connected to the winch. At this time, the winch is on standby, ready to adjust the position of the sleeve as needed. When it is necessary to lift the sleeve, start the winch and rotate it counterclockwise to wind the steel cable. As the steel cable is wound into the winch, it pulls the lifting lug and the sleeve connected to it upward.

[0012] When the sleeve needs to be lowered, start the winch and rotate it clockwise to release the steel cable. The steel cable gradually relaxes and the sleeve slides down the crane pipe under the action of gravity or other auxiliary devices.

[0013] The winch can perform precise speed and position control through the control system to ensure that the sleeve can accurately reach the required height and perfectly dock with the tank port.

[0014] Furthermore, it also includes a sealing ring, which is fixedly connected to the sleeve and cooperates with the crane pipe. The main function of the sealing ring is to prevent liquid materials from leaking from the gap between the crane pipe and the sleeve. This not only protects the environment, but also avoids material loss. In addition to liquid, the sealing ring can also effectively prevent the escape of oil-gas mixture or other volatile organic compounds (VOCs), reducing air pollution and safety hazards.

[0015] Furthermore, a heating mechanism is included, and the sealing ring is a heat expansion member, and the heating mechanism cooperates with the sleeve. When the weather is cold, as the temperature drops, the viscosity of the oil increases significantly, resulting in poor fluidity. High viscosity makes the oil more difficult to pump and transport through pipelines. The design of the heating mechanism and the heat expansion sealing ring enables the crane pipe loading and unloading system to operate stably under extreme temperature conditions and is not affected by the climate.

[0016] The sealing ring is made of materials with good thermal expansion characteristics, such as EPDM (ethylene propylene diene monomer rubber), silicone rubber or specially formulated elastomers to ensure that it can effectively expand and maintain sealing performance when heated.

[0017] Further, the heating mechanism comprises a rotating shaft, a baffle, a connecting rod, a piston rod and a piston, the sleeve is provided with an inner groove, the sealing ring is located inside the inner groove, the rotating shaft is rotatably connected to the sleeve, a plurality of baffles are provided, and the plurality of baffles are distributed in a circle with the rotating shaft as the center, the baffle is fixedly connected to the rotating shaft, and the baffle is matched with the sleeve; One end of the connecting rod is hinged to the baffle, and the other end is hinged to the piston rod. The other end of the piston rod is hinged to the piston. The piston is slidably and sealingly connected to the inner groove, and the piston is provided with an exhaust hole.

[0018] The baffle, connecting rod and piston rod are of a crank slider structure, and the lengths of the baffle, connecting rod and piston rod are designed according to the crank slider structure. When the crane pipe starts to transport oil, the oil will hit the baffle through the crane pipe, causing the baffle to rotate under force. The rotation of the baffle will drive the connecting rod to move, and the connecting rod will drive the piston rod to reciprocate, causing the piston to reciprocate in the inner groove. Since the exhaust hole is small, the air will be compressed every time it moves, causing the temperature of the inner groove to rise. The increase in the temperature of the inner groove will cause the temperature of the sealing ring to rise, and the sealing ring will expand, making the crane pipe unable to move, preventing the crane pipe from moving when transporting oil.

[0019] At the same time, the baffle can block the high-velocity oil flow, acting as a buffer to prevent the oil from flowing too fast and causing excessive impact, leading to impact and fire.

[0020] Furthermore, a buffer pad is also included, which is fixedly connected to the sleeve and is located below the sleeve. The buffer pad can reduce the impact force of the oil and prevent the oil from being too strong and causing friction fire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] Basically as attached Figure 1 , Figure 2 As shown: The present invention provides an exhaust gas collection device which also serves as a sleeve for a telescopic loading crane pipe, including a sleeve 4, a sealing cover 1, a telescopic mechanism, a heating mechanism, an air pipe 3 and a collecting box. The sleeve 4 is used to be sleeved on the periphery of the crane pipe 6, and the sleeve 4 is slidably arranged with the crane pipe 6. The sealing cover 1 is used to cover the oil tank, and the sealing cover 1 cooperates with the oil tank; the collecting box is used to collect exhaust gas; one end of the air pipe 3 is connected to the sealing cover 1, and the other end is connected to the collecting box. The air pipe 3 can be a soft air duct connected by a clamp. The sealing cover 1 is also provided with an inspection port 2, and the inspection port 2 is sealed with a flange or a cover plate. The inspection port 2 is used for the staff to observe the internal situation.

[0024] The outer diameter of the sleeve 4 is 350 mm, the height is 1450 mm, the sealing cover 1 is an umbrella-shaped cover with an angle of 45 degrees and a width of 630 mm at the bottom opening.

[0025] As attached Figure 1 , Figure 3 As shown: The telescopic mechanism is used to move the sleeve 4. The telescopic mechanism includes a winch, a steel cable and a lifting lug 13. The lifting lug 13 is fixedly connected to the sleeve 4. The sleeve 4 is slidably connected to the crane tube 6. One end of the steel cable is fixedly connected to the lifting lug 13, and the other end is fixedly connected to the winch. The sleeve 4 is welded to the top of the umbrella cover. The lifting lug 13 is connected to the steel cable. The winch set on the loading platform drags the steel cable to realize the up and down movement of the telescopic sleeve 4. The diameter of the hole of the lifting lug 13 is 20mm.

[0026] It also includes a sealing ring 5, which is fixedly connected to the sleeve 4 and cooperates with the crane pipe 6. The main function of the sealing ring 5 is to prevent liquid materials from leaking from the gap between the crane pipe 6 and the sleeve 4. This not only protects the environment, but also avoids material loss. In addition to liquid, the sealing ring 5 can also effectively prevent the escape of oil-gas mixture or other volatile organic compounds (VOCs), reducing air pollution and safety hazards.

[0027] It also includes a buffer pad 12, which is fixedly connected to the sleeve 4 through a connecting rod 8, and the buffer pad 12 is located below the sleeve 4. The buffer pad 12 can slow down the impact of the oil and prevent the oil from being too large and causing friction fire.

[0028] It also includes a heating mechanism. The sealing ring 5 is a heat expansion component. The sealing ring 5 is made of a material with good heat expansion characteristics, such as EPDM (ethylene propylene diene monomer rubber), silicone rubber or a specially formulated elastomer to ensure that it can effectively expand and maintain sealing performance when heated.

[0029] like Figure 3 , Figure 4 As shown: The heating mechanism includes a rotating shaft 10, a baffle 9, a connecting rod 11, a piston rod 14 and a piston 15. The sleeve 4 is provided with an inner groove 7, and the sealing ring 5 is located inside the inner groove 7. The rotating shaft 10 is rotatably connected to the buffer pad 12. A plurality of baffles 9 are provided, and the plurality of baffles 9 are distributed in a circle with the rotating shaft 10 as the center. The baffle 9 is fixedly connected to the rotating shaft 10, and the baffle 9 is located below the sleeve 4. When the oil passes through the buffer pad 12, it will impact the baffle 9, causing the baffle 9 to rotate.

[0030] One end of the connecting rod 11 is hinged to the baffle 9, and the other end is hinged to the piston rod 14. The other end of the piston rod 14 is hinged to the piston 15. The piston 15 is slidably and sealedly connected to the inner groove 7. The piston 15 is provided with an exhaust hole 16. The baffle 9, the connecting rod 11 and the piston rod 14 are a crank slider structure, and the lengths of the baffle 9, the connecting rod 11 and the piston rod 14 are designed according to the crank slider structure.

[0031] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown: The principle of this scheme is that the sleeve 4 is sleeved on the outer periphery of the crane pipe 6, and the winch is started to rotate counterclockwise to wind the steel cable. As the steel cable is wound into the winch, it pulls the lifting lug 13 and the sleeve 4 connected thereto to move upward, and the position of the sleeve 4 is adjusted so that the sealing cover 1 covers the oil tank.

[0032] When the crane pipe 6 starts to deliver oil to the oil tank, The oil will hit the buffer pad 12 through the pump pipe 6 to prevent liquid splashing, and then the oil will hit the baffle 9, causing the baffle 9 to rotate under force. The rotation of the baffle 9 will drive the connecting rod 11 to move, and the connecting rod 11 will drive the piston rod 14 to reciprocate, causing the piston 15 to reciprocate in the inner groove 7. Since the exhaust hole 16 is small, the air will be compressed each time it moves, causing the temperature of the inner groove 7 to rise. The temperature rise of the inner groove 7 will cause the temperature of the sealing ring 5 to rise, and the sealing ring 5 will expand, making the pump pipe 6 unable to move, thereby preventing the pump pipe 6 from moving when transporting oil.

[0033] At the same time, the liquid flows into the oil tank quickly, causing the pressure in the oil tank to increase. As the liquid enters the oil tank, the original gas (including air and possible oil-gas mixture) is squeezed out. At this time, the gas in the sealing cover 1 is guided to the collection box through the air pipe 3 instead of being released directly into the environment. The collection box receives and treats these exhaust gases through appropriate methods, such as adsorption, condensation or other purification technologies to reduce the emission of harmful substances.

[0034] The beneficial effects of this solution are: 1. The sleeve 4 ensures that the crane pipe 6 maintains the correct posture during loading and unloading and moves along the predetermined path. 2. The design of the sealing cover 1 and the collection box effectively reduces the emission of harmful gases such as VOCs, meeting strict environmental protection standards. 3. The risk of fire or explosion caused by leakage of oil and gas mixture is prevented, and the safety of operation is improved. 4. The baffle 9 can block high-velocity oil flow and play a buffering effect to prevent the oil flow rate from being too fast and the impact from being too large, resulting in impact and fire. At the same time, the crane pipe 6 can be heated to prevent the oil temperature from being too low and solidifying, and the sealing ring 5 can be heated to expand the sealing ring 5, so that the crane pipe 6 cannot slide, thereby enhancing the sealing performance.

[0035] The above are only embodiments of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
