Description

Technical Field

[0001] The utility model relates to the technical field of lifting and positioning, in particular to a hanging through-pipe lifting and positioning structure used outside a constant temperature oil tank. Background Art

[0002] Thermocouples are commonly used temperature measurement components, primarily for temperature measurement. To ensure their accuracy, they must be regularly tested using a constant-temperature oil bath. This involves inserting a standard thermocouple into the bath along with several thermocouples to be tested. The oil heats the thermocouples, and the temperature difference between the test thermocouple and the standard thermocouple is compared. If the temperature difference is too large, the thermocouple is deemed unqualified.

[0003] Before testing thermocouples, they need to be inserted into through-tubes one by one, and then the through-tubes and thermocouples are inserted into the oil inside the constant temperature oil tank. Currently, this operation is mainly done manually, and the through-tubes are clamped one by one on the positioning plate, which is complicated and laborious to install or remove. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hanging through-tube lifting and positioning structure for the outside of a constant temperature oil tank. The structure adopts an automatic lifting method to drive the through-tube and the thermocouple. When the through-tube and the thermocouple are fixed, the through-tube and the thermocouple are temporarily inserted, and finally all the through-tubes are positioned in one step by the head contacting the top core, so that it saves time and effort when installing or disassembling.

[0005] In order to solve the above technical problems, the technical solution of the utility model is achieved as follows:

[0006] A suspended through-pipe lifting and positioning structure for use outside a constant-temperature oil tank, comprising a clamping mechanism, a vertical lifting mechanism, and a one-step through-pipe positioning assembly;

[0007] The one-step through-tube positioning assembly includes a positioning disc with a plurality of through-holes arranged in a circumferential array. A standard socket is fixedly installed in each through-hole. The standard socket is inserted into the through-tube and a thermocouple located in the through-tube. The thermocouple includes one standard thermocouple and the rest are thermocouples to be tested. The through-tube and the thermocouple located in the through-tube are extended into the oil in the constant temperature oil tank by the drive of the vertical lifting mechanism.

[0008] One side of each standard socket is provided with a socket facing the center of the positioning disc, and a top core is slidably installed in each socket; a vertically arranged screw rod is threadedly installed at the center of the positioning disc, and the end of the screw rod is connected to a top head, which can completely fix the through pipes in all standard sockets when the top head abuts against the top core.

[0009] By adopting the above scheme, the structure drives the through-tube and the thermocouple in an automatic lifting manner. When fixing the through-tube and the thermocouple, the through-tube and the thermocouple are temporarily inserted, and finally all the through-tubes are positioned in one step by the head contacting the top core, which saves time and effort when installing or disassembling.

[0010] As a preferred embodiment of a suspended through-tube lifting and positioning structure for use outside a constant-temperature oil tank, the standard socket is a rubber sleeve, and the fitting relationship between the standard socket and the through-tube is an interference fit.

[0011] By adopting the above solution, in order to facilitate the replacement of different types of through pipes, it is only necessary to match the standard socket that works better with it, without having to replace the entire positioning disc to adapt to it, which will be more economical in later use.

[0012] As a preferred embodiment of a suspended through-tube lifting and positioning structure used outside a constant temperature oil tank, the plug is a cone.

[0013] With the above solution, in order to achieve the abutment of the plug, the plug is designed to be a cone. As the screw is rotated, the plug will continuously abut against the core until the through pipe is completely fixed.

[0014] As a preferred embodiment of a suspended through-tube lifting and positioning structure used outside a constant-temperature oil tank, the ends of the top core that contact the through-tube and the top head are both round heads.

[0015] With the above solution, in order to reduce the friction during the collision, the end of the top core is designed to be a round head. Due to the small contact area, the friction is reduced.

[0016] As a preferred embodiment of a suspended through-tube lifting and positioning structure used outside a constant temperature oil tank, the clamping mechanism includes a reference seat, with clamping seats installed on both sides of the reference seat. The clamping seats are slidably installed on the sides of the clamping seat through sliding rods, and top rods that abut against the clamping seat are respectively installed on both sides of the clamping seat through threads; the reference seat is an N-shaped seat, and the clamping seat is an L-shaped seat; the ends of the top rods that contact the clamping seat are both round heads.

[0017] By adopting the above scheme, in order to achieve the clamping positioning of the clamping mechanism, the top rod is rotated, and the clamping seat is continuously pushed forward under the resistance of the top rod. Under the joint action of the two clamping seats, it is clamped and fixed above the constant temperature oil tank.

[0018] As a preferred embodiment of a suspended through-pipe lifting and positioning structure used outside a constant temperature oil tank, the vertical lifting mechanism includes a lifting platform fixed above a reference seat with screws, a lead screw is rotatably installed inside the lifting platform, the lead screw is driven to rotate by a motor fixed above the lifting platform, a lifting seat is threadedly installed on the lead screw, and a lifting frame is detachably installed on one side of the lifting seat; a slide rail parallel to the lead screw is also fixed inside the lifting platform, and the lifting seat is also slidably installed on the slide rail; the lifting seat and the lifting frame are connected to each other by a pin, and both ends of the pin are respectively inserted into a pin for blocking.

[0019] By adopting the above solution, in order to realize automatic lifting, the motor drives the screw to rotate, and under the action of the thread, the lifting seat is lifted vertically, thereby driving the one-step through-tube positioning assembly on the lifting frame to lift vertically.

[0020] After adopting the above technical solution, the beneficial effects of the utility model are:

[0021] 1. This structure uses an automatic lifting method to drive the through-tube and thermocouple. When fixing the through-tube and thermocouple, the through-tube and thermocouple are temporarily inserted, and finally all the through-tubes are positioned in one step by the push-head against the push-core, which saves time and effort when installing or removing.

[0022] 2. In order to facilitate the replacement of different types of through pipes, it is only necessary to match the standard socket that works better with it, without having to replace the entire positioning disc to adapt to it. This will be more economical in later use;

[0023] 3. In order to achieve the abutment of the plug, the plug is designed to be conical. As the screw rotates, the plug will continuously abut the core until the through-tube is completely fixed.

[0024] 4. In order to reduce the friction during the collision, the end of the top core is designed to be round. Due to the small contact area, the friction will be reduced;

[0025] 5. In order to realize the clamping positioning of the clamping mechanism, the top rod is rotated, and the clamping seat is continuously pushed forward under the resistance of the top rod. Under the joint action of the two clamping seats, it is clamped and fixed above the constant temperature oil tank;

[0026] 6. In order to realize automatic lifting, the motor drives the screw to rotate. Under the action of the thread, the lifting seat is lifted vertically, thereby driving the one-step through-tube positioning assembly on the lifting frame to lift vertically. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] like Figures 1 to 9 As shown, a suspension type through-tube lifting and positioning structure for the outside of a constant temperature oil tank comprises a clamping mechanism 1, a vertical lifting mechanism 2 and a one-step through-tube positioning assembly 3; the one-step through-tube positioning assembly 3 comprises a positioning disc 301, on which a plurality of through-holes distributed in a circumferential array are formed, and a standard socket 302 is fixedly installed in each through-hole, and a through-tube 5 and a thermocouple 6 located in the through-tube 5 are inserted into the standard socket 302, and the thermocouple 6 includes one standard thermocouple 6 and the rest are thermocouples 6 to be tested; the through-tube 5 and Driven by the vertical lifting mechanism 2, the thermocouple 6 located in the through-tube 5 extends into the oil in the constant-temperature oil tank 4. A socket 303 facing the center of the positioning disc 301 is provided on one side of each standard socket 302, and a top core 304 is slidably installed in each socket 303. A vertically arranged screw 305 is threadedly installed at the center of the positioning disc 301, and the end of the screw 305 is connected to a top core 306. When the top core 306 abuts the top core 304, the through-tube 5 in each standard socket 302 can be completely fixed. This structure uses an automatic lifting method to drive the through-tube 5 and thermocouple 6. When fixing the through-tube 5 and thermocouple 6, the through-tube 5 and thermocouple 6 are temporarily inserted, and finally the top core 304 is abutted by the top core 306 to complete the positioning of all the through-tubes 5 in one step, making it both time-saving and labor-saving when installing or removing.

[0044] like Figures 7 to 9As shown, the standard socket 302 is a rubber sleeve, and the fitting relationship between the standard socket 302 and the through tube 5 is an interference fit. To facilitate the replacement of different types of through tubes 5, only the standard socket 302 that better cooperates with it is required, without having to replace the entire positioning disc 301 to adapt to it. This is more economical in later use.

[0045] like Figures 7 to 9 As shown, the plug 306 is a cone. In order to achieve the abutment of the plug 306, the plug 306 is designed to be a cone, and as the screw 305 is rotated, the plug 306 will continuously abut the core 304 until the through pipe 5 is completely fixed.

[0046] like Figures 7 to 9 As shown, the ends of the top core 304 that contact the through pipe 5 and the top head 306 are round heads. In order to reduce the friction during the collision, the end of the top core 304 is designed to be rounded, and since the contact area is small, the friction is reduced.

[0047] like Figures 10 and 11 As shown, the clamping mechanism 1 includes a reference base 101, with clamping bases 102 mounted on both sides of the reference base 101. The clamping bases 102 are slidably mounted on the sides of the clamping base 102 via slide bars 103. A push rod 104 is threadedly mounted on both sides of the clamping base 102, which contacts the clamping base 102. The reference base 101 is an N-shaped base, while the clamping base 102 is an L-shaped base. The ends of the push rods 104 that contact the clamping base 102 are both rounded. In order to achieve the clamping and positioning of the clamping mechanism 1, the push rods 104 are rotated, and the push rods 104 continuously push the clamping base 102 forward under the interference of the push rods 104. Under the joint action of the two clamping bases 102, it is clamped and fixed above the constant temperature oil tank 4.

[0048] like Figures 12 to 13 As shown, the vertical lifting mechanism 2 includes a lifting platform 201 fixed above the reference base 101 with screws. A screw rod 202 is rotatably mounted inside the lifting platform 201. The screw rod 202 is driven to rotate by a motor 203 fixed above the lifting platform 201. A lifting seat 204 is threadedly mounted on the screw rod 202, and a lifting frame 205 is detachably mounted on one side of the lifting seat 204. A slide rail 206 is also fixedly mounted inside the lifting platform 201 and is parallel to the screw rod 202. The lifting seat 204 is also slidably mounted on the slide rail 206. The lifting seat 204 and the lifting frame 205 are connected to each other by a latch 207, and the ends of the latch 207 are respectively inserted into stop pins 208 for blocking. To achieve automated lifting, the motor 203 drives the screw rod 202 to rotate. Under the action of the threads, the lifting seat 204 is vertically raised and lowered, thereby driving the one-step pipe positioning assembly 3 on the lifting frame 205 to rise and fall vertically.

[0049] The working principle of this utility model:

[0050] First, the clamping mechanism 1 is clamped and fixed on the constant temperature oil tank 4. By rotating the top rod 104, the clamping seat 102 is continuously pushed forward under the resistance of the top rod 104. Under the joint action of the two clamping seats 102, it is clamped and fixed above the constant temperature oil tank 4.

[0051] Secondly, the position of the one-step pipe positioning assembly 3 is adjusted by the vertical lifting mechanism 2. The motor 203 drives the screw rod 202 to rotate, and under the action of the thread, the lifting seat 204 is vertically lifted and lowered, thereby lifting the one-step pipe positioning assembly 3 to a high position.

[0052] Finally, the through-tube 5 and the thermocouple 6 are installed on the one-step through-tube positioning assembly 3. The through-tube 5 is temporarily inserted into the standard socket 302, and a standard thermocouple 6 is placed in the through-tube 5. The rest are the thermocouples 6 to be tested. Finally, the plug 306 is pressed against the core 304 to complete the positioning of all the through-tubes 5 in one step. After heating them with oil, the temperature difference between the thermocouple to be tested 6 and the standard thermocouple 6 is compared. If the temperature difference is too large, the tested thermocouple 6 is unqualified, which saves time and effort during installation or removal.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
