Description

Technical Field

[0001] The invention relates to the field of autoclaves, and in particular to intelligent bridging equipment for entering and exiting an autoclave of concrete products. Background Art

[0002] Autoclave, also known as steam curing autoclave or pressure autoclave, is a large pressure vessel with a large volume and heavy weight. Autoclave has a wide range of uses and is widely used in the autoclave curing of building materials such as aerated concrete blocks and concrete pipe piles. In actual production, several autoclaves are usually arranged in parallel in a pit for work. There is an autoclave door at the end of the autoclave. The opening and closing of the autoclave door requires a certain amount of space. There is usually a certain height difference between the rail inside the autoclave and the lowest point of the inner wall of the autoclave. Therefore, a certain distance needs to be left from the autoclave door to the end of the floor rail at the external loading station to provide space for the opening and closing of the autoclave door. Concrete products entering the autoclave for curing are usually stacked on the autoclave car, which is pulled into the autoclave along the rails. A bridge track equipment must be set up between the autoclave door and the floor rails to connect the rails inside and outside the autoclave into a complete set of tracks, so that the autoclave car can smoothly enter and exit the autoclave along the rails.

[0003] In the prior art, usually a steel pipe hole is embedded on each side of the concrete foundation floor of the pit, a steel column is installed in the steel pipe hole, a flat flange is welded on the upper end face of the steel column, and the bridge rail is inserted into the gap between the rail in the autoclave and the rail on the loading floor, and the joint of the rail is manually connected by pins. Manual operation and handling of the rails are labor-intensive, have many safety hazards, and are inefficient. There is also a trolley bridge, where the rails are placed obliquely on the trolley, and the trolley is manually pushed into place, and then the bridge rails on the trolley are manually carried and embedded into the gap of the pit, and then The pins are inserted into the positioning sleeves at the ends of the rails for positioning and connection. The installation and disassembly of the entire bridge track requires manual participation, resulting in high labor intensity and low efficiency. In addition, workers are prone to damage the autoclave door during the operation of the bridge track, resulting in loss of personnel and equipment. Moreover, manual handling of the rails requires workers to operate at the maintenance site of the autoclave, but the temperature of the autoclave is high, the pressure vessel is highly dangerous, and the autoclave end has poor visibility and poor environment due to the discharged steam, which makes safety accidents prone to occur, posing great risks. Summary of the invention

[0004] The present invention provides an intelligent bridge-building device for entering and exiting a concrete product autoclave, wherein the installation and disassembly of the entire bridge track do not require manual handling, and the work efficiency is high; the work process is programmed, the operation is precise, and the autoclave will not be damaged; the entire process does not require workers to operate at the maintenance site of the autoclave, and the personal safety of the operators will not be endangered, thereby solving the above-mentioned technical problems.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] An intelligent bridge-building device for entering and exiting a concrete product autoclave is arranged in a pit, an autoclave is arranged in the pit, an operation interval is formed between the autoclave door of the autoclave and the side wall of the pit, an autoclave inner track is arranged inside the autoclave, and an autoclave outer track corresponding to the autoclave inner track is arranged on the floor outside the operation interval. The intelligent bridge-building device is arranged in the operation interval, and comprises: a bridge track, a rotating member, a supporting member and a walking member, the length of the bridge track is not greater than the distance between the autoclave inner track and the autoclave outer track, and the bridge track can connect the autoclave inner track and the autoclave outer track; the rotating member comprises a rotating shaft and a rotating drive The moving part, the rotating shaft and the bottom of the bridge track are connected, the rotating driving part is connected to the rotating shaft, and the rotating driving part is used to drive the rotating shaft to rotate, so that the bridge track has a first state and a second state; in the first state, the bridge track and the track inside the kettle are perpendicular to each other; in the second state, the bridge track and the track inside the kettle are parallel, so that the two ends of the bridge aisle are respectively connected to the track inside the kettle and the track outside the kettle; the supporting part is connected to the rotating shaft, so that the rotating shaft maintains a vertical upward state; a supporting part is provided on the top of the walking part, and the walking part can enable the supporting part to move in the pit in a direction perpendicular to the track inside the kettle.

[0007] The present invention adopts the above structure so that the installation and disassembly of the entire bridge track does not require manual handling, and the work efficiency is high; the work process is programmed, the operation is precise, and the autoclave will not be damaged; workers are not required to operate at the maintenance site of the autoclave, and the personal safety of the operators will not be endangered.

[0008] In a preferred implementation, two groups of rotating parts are provided; in the second state, the length of the bridge track between the two rotating shafts is less than the shortest straight-line distance on the same horizontal plane between the two rotating shafts, so that the bridge tracks do not interfere with each other during rotation along the rotating shafts.

[0009] In a preferred implementation, the distance between the two rotating shafts in a direction perpendicular to the inner track of the kettle is the same as the straight-line distance between the two inner track of the kettle, the two rotating shafts are staggered in a direction parallel to the inner track of the kettle, and the two rotating shafts are symmetrically arranged on both sides of the distance center between the inner track of the kettle and the outer track of the kettle, the connection position of the rotating shaft and the bridge track is set as the rotation center, and long-distance segments and short-distance segments are formed on both sides of the rotation center of the bridge track, and when the first state is changed to the second state, the long-distance segment and the short-distance segment respectively rotate 90 degrees along the rotating shaft.

[0010] The distance between the two rotating shafts in a direction perpendicular to the inner track of the kettle is the same as the straight-line distance between the two inner track of the kettle, so that after the rotating shafts are positioned once, the two rotating shafts can be simultaneously located at positions corresponding to the two sets of inner track of the kettle and the outer track of the kettle, with high efficiency and accurate positioning; the two rotating shafts are staggered in a direction parallel to the inner track of the kettle so that the two bridge tracks do not interfere with each other during the rotation process, making the rotation process smoother and more stable; and the two rotating shafts are symmetrically arranged on both sides of the distance center between the inner track of the kettle and the outer track of the kettle so that the length difference between the long-distance section and the short-distance section formed when the bridge track takes the connection position of the rotating shaft and the bridge track as the rotation center is smaller, making the state of the bridge track more balanced and stable.

[0011] In a preferred implementation, two groups of rotating parts are provided; in the second state, the length of the bridge track between the two rotating shafts is greater than the shortest straight-line distance on the same horizontal plane between the two rotating shafts, so that the bridge tracks interfere with each other during rotation along the rotating shafts.

[0012] In a preferred implementation, the intelligent bridge-building equipment also includes a lifting member, which includes a guide part and a lifting drive member. The two ends of the guide part are respectively connected to a support member and a rotating shaft. The rotating shaft and the guide part are rotatably connected. The lifting drive member and the guide part are connected, so that the guide part can move in a vertical direction and the bridge track can move in a vertical direction.

[0013] The setting of the lifting parts makes it possible to flexibly adjust the height of the bridge rails when the bridge rails interfere with each other during rotation along the rotating shaft, so as to form a vertical height misalignment between the two bridge rails, which can effectively avoid mutual collision during the rotation of the two rails.

[0014] In a preferred implementation, the guide portion is configured as a telescopic cylinder, the lifting drive member is disposed at the bottom of the telescopic cylinder, the lifting member is provided with a through hole for the lifting drive member to pass through, and the movable end of the lifting drive member passes through the through hole and then connects to the movable portion of the telescopic cylinder.

[0015] In a preferred implementation, the lifting drive member is configured as an oil cylinder, an air cylinder or an electric push rod.

[0016] In a preferred implementation, the intelligent bridge-building equipment also includes a positioning member, which includes a positioning part, a positioning pin and a push-pull member. The push-pull member is connected to the positioning pin so that the positioning pin reciprocates along the laying direction of the inner and outer tracks of the kettle, and the positioning part is provided with a pin hole that cooperates with the positioning pin; positioning pins and push-pull members are provided at both ends of the bridge track, and positioning parts are respectively provided at corresponding positions of the inner and outer tracks of the kettle; or positioning parts are provided at both ends of the bridge track, and positioning pins and push-pull members are respectively provided at corresponding positions of the inner and outer tracks of the kettle.

[0017] When the bridge track is assembled with the inner track and outer track of the kettle, the push-pull parts in the positioning parts will push the positioning pins into the pin holes of the positioning parts. This makes the coordination between the bridge track and the inner track and outer track of the kettle more stable, and there will be no misalignment after the track is spliced, which can ensure the smooth operation of the kettle car on the track.

[0018] In a preferred implementation, one end of the inner track and the outer track of the kettle connected to the bridge track is also provided with a V-shaped groove for accommodating the bridge track.

[0019] The V-shaped groove can accommodate the inner track of the kettle and the bridge track. During the assembly process of the bridge track, the V-shaped groove can provide a certain guiding effect for the bridge track. After the assembly is completed, the V-shaped groove also has a limiting effect on the connected inner track of the kettle and the bridge track, which is beneficial to improve the stability of the track.

[0020] In a preferred implementation, the intelligent bridge-building equipment also includes a limit switch, which is arranged in a direction perpendicular to the track inside the kettle. In the first state, the intelligent bridge-building equipment moves driven by the walking parts, which can trigger the limit switch so that the two ends of the bridge track correspond to the track inside the kettle and the track outside the kettle respectively.

[0021] This structure enables the intelligent bridge-building equipment to be automated. When it reaches the specified position, it will trigger the limit switch, allowing the bridge track to start the entire assembly process. The entire process is completed by the intelligent bridge-building equipment itself without human participation, with high work efficiency and high safety.

[0022] The walking parts include a motor, which is connected to a drive shaft, which is connected to a walking wheel. When the intelligent bridge-building device triggers a limit switch, the limit switch sends a signal to a controller, which receives and processes the signal and controls the motor to stop rotating. It is understandable that a brake structure may also be included. When the limit switch is triggered, the motor and the brake structure may be operated simultaneously to ensure that the intelligent bridge-building device stops accurately at the corresponding position. The brake structure may directly adopt existing technology and utilize electric brake technology, which will not be described in detail here.

[0023] Furthermore, the limit switch can be set with a deceleration switch and a stop switch. During the movement of the intelligent bridge-building equipment, the deceleration switch will be triggered first. At this time, the controller sends a stop signal to the motor, and the motor stops, but the intelligent bridge-building equipment will continue to move forward due to inertia. The pre-set deceleration switch reserves a stroke for the inertial sliding of the intelligent bridge-building equipment. When the bridge track moves to the position corresponding to the track inside the kettle and the track outside the kettle, the intelligent bridge-building equipment triggers the stop switch. At this time, the controller controls the action of the brake structure to lock the intelligent bridge-building equipment steadily in the corresponding position.

[0024] The beneficial effects of the above structure of the present invention are: the installation and disassembly of the entire bridge track does not require manual handling, and the work efficiency is high; the work process is programmed, the operation is precise, and the autoclave will not be damaged; workers are not required to operate at the maintenance site of the autoclave, and the personal safety of the operators will not be endangered.

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0041] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0042] like Figure 1-Figure 10 As shown: an intelligent bridge-building device for entering and exiting a concrete autoclave, which is arranged in a pit 202, in which an autoclave 1 is arranged, an operation interval is formed between a door 101 of the autoclave 1 and a side wall of the pit 202, an autoclave inner track 102 is arranged inside the autoclave 1, and a floor 2 outside the operation interval is provided with an autoclave outer track 201 corresponding to the autoclave inner track 102, and an intelligent bridge-building device 3 is arranged in the operation interval, which includes: a bridge track 301, a rotating part 302, a supporting part 303 and a walking part 304, the length of the bridge track 301 is not greater than the distance between the autoclave inner track 102 and the autoclave outer track 201, and the bridge track 301 can connect the autoclave inner track 102 and the autoclave outer track 201;

[0043] The rotating member 302 includes a rotating shaft 3021 and a rotating driving member 3022. The rotating shaft 3021 is connected to the bottom of the bridge track 301. The rotating driving member 3022 is connected to the rotating shaft 3021. A rolling bearing is provided between the rotating driving member 3022 and the rotating shaft 3021. The rotating driving member 3022 is used to drive the rotating shaft 3021 to rotate, so that the bridge track 301 has a first state and a second state. In the first state, the bridge track 301 is perpendicular to the track 102 in the kettle, that is, Figure 3 , Figure 5 , Figure 6 In the second state, the bridge track 301 and the kettle track 102 are parallel, that is, Figure 4, Figure 7 The two ends of the bridge aisle 301 are respectively connected to the inner track 102 and the outer track 201 of the kettle; the support member 303 is connected to the rotating shaft 3021, so that the rotating shaft 3021 remains in a vertical upward state; the top of the walking member 304 is provided with a support member 303, and the walking member 304 can enable the support member 303 to move in the pit 202 in a direction perpendicular to the inner track 102 of the kettle.

[0044] The present invention adopts the above structure so that the installation and disassembly of the entire bridge track 301 does not require manual handling, and the work efficiency is high; the work process is programmed, the operation is precise, and the autoclave 1 will not be damaged; workers are not required to operate at the maintenance site of the autoclave 1, and the personal safety of the operators will not be endangered.

[0045] like Figure 2 , Figure 3 As shown, two groups of rotating parts 302 are provided; in the second state, the length of the bridge track 301 located between the two rotating shafts 3021 is less than the shortest straight-line distance on the same horizontal plane between the two rotating shafts 3021, so that the bridge tracks 301 do not interfere with each other during the rotation along the rotating shafts 3021.

[0046] like Figure 2 , Figure 3 , Figure 4 As shown, the distance between the two rotating shafts 3021 in the direction perpendicular to the inner track 102 of the kettle is the same as the straight-line distance between the two inner tracks 102 of the kettle, the two rotating shafts 3021 are staggered in the direction parallel to the inner track 102 of the kettle, and the two rotating shafts 3021 are symmetrically arranged on both sides of the distance center between the inner track 102 of the kettle and the outer track 201 of the kettle, the connection position of the rotating shaft 3021 and the bridge track 301 is set as the rotation center, and the two sides of the rotation center of the bridge track 301 are formed with a long distance segment and a short distance segment. When the first state is changed to the second state, that is, Figure 3 Transformed into Figure 4 and Fig.10 In the state of medium, the long-distance segment and the short-distance segment rotate 90 degrees along the rotation axis respectively.

[0047] The distance between the two rotating shafts 3021 in a direction perpendicular to the inner track 102 of the kettle is the same as the straight-line distance between the two inner track 102 of the kettle, so that after the rotating shaft 3021 is positioned once, the two rotating shafts 3021 can be simultaneously located at positions corresponding to the two groups of inner track 102 of the kettle and the outer track 201 of the kettle, with high efficiency and accurate positioning; the two rotating shafts 3021 are staggered in a direction parallel to the inner track 102 of the kettle, so that the two bridge tracks 301 do not interfere with each other during the rotation process, making the rotation process smoother and more stable; and the two rotating shafts 3021 are symmetrically arranged on both sides of the distance center between the inner track 102 of the kettle and the outer track 201, so that the length difference between the long-distance section and the short-distance section formed when the bridge track 301 takes the connection position of the rotating shaft 3021 and the bridge track 301 as the rotation center is smaller, making the state of the bridge track 301 more balanced and stable.

[0048] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, two groups of rotating members 302 are provided; in the second state, the length of the bridge track 301 between the two rotating shafts 3021 is greater than the shortest straight-line distance on the same horizontal plane between the two rotating shafts 3021, so that the bridge tracks 301 interfere with each other during the rotation process along the rotating shaft 3021.

[0049] like Figure 1 , Figure 2 As shown, the intelligent bridge-building device 3 also includes a lifting member 305, and the lifting member 305 includes a guide part 3051 and a lifting drive member 3052. The two ends of the guide part 3051 are respectively connected to the support member 303 and the rotating shaft 3021. The rotating shaft 3021 and the guide part 3051 are rotatably connected. The lifting drive member 3052 is connected to the guide part 3051, which can move the guide part 3051 in the vertical direction and move the bridge track 301 in the vertical direction. The connection position between the rotating shaft 3021 and the bridge track 301 is set as the rotation center. The two sides of the rotation center of the bridge track 301 are formed with a long distance segment and a short distance segment. When the first state is changed to the second state, that is, Figure 5 Transformed into Figure 7 When the bridge track 301 rotates counterclockwise, the length of the long section in the bridge track 301 rotating counterclockwise is greater than the shortest straight-line distance between the two rotating shafts 3021 in the same horizontal plane. During the rotation of the bridge track 301 rotating counterclockwise, it will be hindered by the rotating member 302 connected to the bridge track 301 rotating clockwise. At this time, the bridge track 301 rotating counterclockwise is lifted to a certain height by the lifting member 305, and the two bridge tracks 301 form a height difference in the vertical direction, that is, the bridge track 301 is converted to the state of rotation. Figure 6In the state in which they do not interfere with each other during the rotation process, the long-distance section and the short-distance section of the two bridge rails 301 are rotated 90 degrees along the rotation axis respectively, and the previously ascending bridge rail 301 is lowered to the same level as the other bridge rail 301, and then switched to Figure 7 , Fig.10 The assembly is completed.

[0050] The setting of the lifting member 305 allows the height of the bridge rail 301 to be flexibly adjusted when the bridge rails 301 interfere with each other during rotation along the rotating shaft 3021, so as to form a vertical height misalignment between the two bridge rails 301, which can effectively avoid mutual collision during rotation.

[0051] like Figure 2 As shown, the guide part 3051 is set as a telescopic cylinder, the lifting drive member 3052 is arranged at the bottom of the telescopic cylinder, the lifting member 305 is provided with a through hole for the lifting drive member 3052 to pass through, and the movable end of the lifting drive member 3052 passes through the through hole and then connects to the movable part of the telescopic cylinder.

[0052] Preferably, the lifting drive member is configured as an oil cylinder, a pneumatic cylinder or an electric push rod.

[0053] like Figure 1 , Figure 8 As shown, the intelligent bridge-building equipment 3 also includes a positioning 306, and the positioning member 306 includes a positioning portion 3061, a positioning pin 3062 and a push-pull member 3063. The push-pull member 3063 is connected to the positioning pin 3062, so that the positioning pin 3062 reciprocates along the laying direction of the inner track 102 and the outer track 201 of the kettle. The positioning portion 3061 is provided with a pin hole that cooperates with the positioning pin 3062; positioning pins 3062 and push-pull members 3063 are provided at both ends of the bridge track 301, and the corresponding positions of the inner track 102 and the outer track 201 of the kettle are respectively provided with positioning portions 3061; or positioning portions 3061 are provided at both ends of the bridge track 301, and the corresponding positions of the inner track 102 and the outer track 201 of the kettle are respectively provided with positioning pins 3062 and push-pull members 3063.

[0054] When the bridge track 301 is assembled with the inner track 102 and the outer track 201 of the kettle, the push-pull member 3063 in the positioning member 306 will push the positioning pin 3062 into the pin hole of the positioning part 3061, so that the cooperation between the bridge track 301 and the inner track 102 and the outer track 201 of the kettle is more stable, and there will be no misalignment after the track splicing, which can ensure the smooth operation of the kettle car on the track.

[0055] like Fig. 9 As shown, one end of the inner track 102 and the outer track 201 connected to the bridge track 301 is also provided with a V-shaped groove 103 for accommodating the bridge track 301 .

[0056] The V-shaped groove 103 can accommodate the inner track 102 of the kettle and the bridge track 301. During the assembly process of the bridge track 301, the V-shaped groove 103 can provide a certain guiding effect for the bridge track 301. After the assembly is completed, the V-shaped groove 103 also has a limiting effect on the connected inner track 102 of the kettle and the bridge track 301, which is beneficial to improve the stability of the track.

[0057] like Figure 3 , Figure 5 and Figure 6 As shown, the intelligent bridge-building device 3 also includes a limit switch 307, and the limit switch 307 is set in a direction perpendicular to the inner track 102 of the kettle. In the first state, the intelligent bridge-building device 3 moves under the drive of the walking member 304, and can trigger the limit switch 307, so that the two ends of the bridge track 301 correspond to the inner track 102 of the kettle and the outer track 201 of the kettle respectively.

[0058] Such a structure enables the intelligent bridge-building device 3 to be automated. When it reaches the specified position, it will trigger the limit switch 307, so that the bridge track 301 starts the entire assembly process. The entire process is completed by the intelligent bridge-building device 3 itself without human intervention, with high work efficiency and high safety.

[0059] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the walking member 304 includes a motor 3041, the motor 3041 is connected to a drive shaft 3042, and the drive shaft 3042 is connected to a walking wheel 3043. When the intelligent bridge-building device 3 triggers the limit switch 307, the limit switch 307 sends a signal to the controller, and the controller receives and processes the signal to control the motor 3041 to stop rotating. It can be understood that a brake structure can also be included. When the limit switch 307 is triggered, the motor 3041 and the brake structure can be operated at the same time to ensure that the intelligent bridge-building device 3 stops accurately at the corresponding position. The brake structure can directly adopt the existing technology and use the electric brake technology, which will not be described in detail here.

[0060] Furthermore, the limit switch 307 can be set with a deceleration switch and a parking switch. During the movement, the intelligent bridge-building device 3 will first trigger the deceleration switch. At this time, the controller sends a stop signal to the motor 3041, and the motor 3041 stops, but the intelligent bridge-building device 3 will continue to move forward due to inertia. The pre-set deceleration switch reserves a travel range for the inertial sliding of the intelligent bridge-building device 3. When the bridge track 301 moves to the position corresponding to the inner track 102 and the outer track 201 of the kettle, the intelligent bridge-building device 3 triggers the parking switch. At this time, the controller controls the action of the brake structure to steadily lock the intelligent bridge-building device 3 in the corresponding position.

[0061] The technical solution protected by the present invention is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any one embodiment with the technical solution of one or more other embodiments is within the protection scope of the present invention. Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present invention. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
