Description

Technical Field

[0001] The present application belongs to the technical field of thermal insulation medium protection equipment, and in particular to a thermal insulation layer sealing mechanism. Background Art

[0002] Steps for preparing the insulation pipe: first, tie a wooden bracket to the working steel pipe, and evenly adjust the spacing between the outer protective pipes; then, move the working steel pipe and the outer protective pipe to the pipe threading platform, perform the pipe threading operation, and prepare the concentric pipe; finally, move the prepared concentric pipe to the foaming platform, and plug flanges at both ends of the concentric pipe to prevent the polyurethane foam from splashing out; in order to better fill the polyurethane foam, open a hole in the middle of the outer protective pipe, align the discharge port of the high-pressure foaming machine with the opened hole to prepare for filling, adjust the parameters, start filling the polyurethane foam, plug it after filling, and complete the preparation of the insulation pipe.

[0003] After the insulation pipe is prepared, first remove the flanges at both ends of the insulation pipe, and then remove the insulation pipe from the foaming platform. At this time, the polyurethane foam material at both ends of the insulation pipe will be exposed to the air. However, in actual production applications, the insulation pipe is not put into use immediately. At this time, in order to prevent moisture or dust from invading the insulation pipe through the exposed polyurethane foam material at both ends of the insulation pipe, it is necessary to seal the two ends of the insulation pipe when storing the insulation pipe. In fact, it is to seal the exposed polyurethane foam material at both ends of the insulation pipe. In the prior art, most of the two ends of the insulation pipe are manually wrapped with plastic to protect the exposed polyurethane foam material at both ends of the insulation pipe, but this operation step is time-consuming and laborious.

[0004] Therefore, in order to improve the sealing efficiency of the exposed polyurethane foam at both ends of the insulation pipe, that is, the sealing efficiency of the insulation layer of the insulation pipe, an insulation layer sealing mechanism is urgently needed. Summary of the invention

[0005] In view of this, it is necessary to provide an insulation layer sealing mechanism that can improve the sealing efficiency of the insulation layers at both ends of the insulation pipe.

[0006] The solution of this application to solve the technical problem is:

[0007] A heat preservation layer sealing mechanism, the heat preservation layer sealing mechanism is arranged at both ends of a heat preservation pipe, the heat preservation pipe is arranged on a foaming platform, and comprises a baffle placement box, a spring and a plurality of neatly arranged baffles are arranged in sequence in the baffle placement box, the spring is used to push the baffle to move, the baffle placement box is provided with a baffle outlet, and the outermost baffle can move downward along the baffle outlet;

[0008] A limit block, the limit block can move up and down, and the limit block contacts the outermost baffle, in a first state, the limit block pushes the outermost baffle to move downward; in a second state, the limit block moves upward and fixes the baffle in the baffle placement box;

[0009] A push rod, which can move horizontally, is used to push the baffle plate moved out from under the baffle plate outlet.

[0010] Preferably, the limit block is a triangular limit block.

[0011] Preferably, the baffle is a circular baffle.

[0012] Preferably, the push rod includes a first push rod and a second push rod, and the first push rod and the second push rod are symmetrically arranged to push the baffle to move out from under the baffle outlet.

[0013] Preferably, a circular ring is provided at the front end of the push rod, and the outer diameter of the circular ring is smaller than the outer diameter of the circular baffle, and the inner diameter of the circular ring is larger than the inner diameter of the circular baffle.

[0014] Preferably, it also includes an auxiliary platform, the auxiliary platform is provided with a concave groove, and the concave groove is provided with a groove, the auxiliary platform is arranged below the baffle outlet, and the height of the auxiliary platform is flush with the inner diameter of the outer protective tube of the insulation tube.

[0015] Preferably, a plurality of stacked concave groove plates are arranged in the concave groove, the upper end surface of the concave groove plate is provided with a card slot, and the lower end surface is provided with a protrusion, the protrusion is card-engaged with the groove, and two adjacent concave groove plates are detachably connected to the card slot through the protrusion.

[0016] Beneficial effect: The present application discloses a heat-insulating layer sealing mechanism arranged at both ends of a foaming platform, which utilizes the characteristics of the spring itself. Under the action of the spring force, the outermost baffle is pushed out to the baffle outlet. At this time, the limit block moves downward, pushing the baffle at the baffle outlet to move downward. When the limit plate presses the baffle out of the baffle placement box as a whole, the push rod contacts the pressed baffle, and then pushes the baffle to be sleeved on the heat-insulating pipe. As the push rod moves forward, the baffle contacts the heat-insulating material in the heat-insulating pipe, and then the heat-insulating material is used to seal the baffle. The stickiness of the material fixes the baffle on the insulation pipe, thereby protecting the exposed insulation materials at both ends of the insulation pipe, and in the process of the limit block moving downward, the compression spring prevents the movement of the next baffle in the baffle placement box; at the same time, when the baffle is installed, the push rod returns to the original path, and the limit block moves upward, and when the limit block moves to the top, under the pressure of the spring, the next baffle in the baffle placement box is pushed to the baffle outlet and contacts the limit block, and the next work process is carried out again, which is fast and convenient.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0023] Please see Figures 1 to 4, a heat preservation layer sealing mechanism, the heat preservation layer sealing mechanism is arranged at both ends of the heat preservation tube 50, the heat preservation tube 50 is arranged on the foaming platform, and includes a baffle placement box 10, in which a spring 101 and a plurality of neatly arranged baffles 102 are arranged in sequence, the spring 101 is used to push the baffle 102 to move, the baffle placement box 10 is provided with a baffle outlet 103, and the outermost baffle 102 can move downward along the baffle outlet 103;

[0024] The limit block 20 can move up and down, and the limit block 20 contacts the outermost baffle 102. In the first state, the limit block 20 pushes the outermost baffle 102 to move downward; in the second state, the limit block 20 moves upward and fixes the baffle 102 in the baffle placement box 10;

[0025] The push rod 30 can move horizontally and is used to push the baffle 102 that moves out from under the baffle outlet 103 to move.

[0026] When the foaming platform injects polyurethane foam material into the insulation tube 50 (to form the insulation layer 501 of the insulation tube 50), the insulation layer sealing mechanism starts to move, that is, the baffle 102, the limit block 20 and the push rod 30 start to move, and the limit block 20 first pushes the baffle 102 to move, and then the push rod 30 starts to move, ensuring that the push rod 30 can push the baffle 102 to move, thereby avoiding the situation where the push rod 30 and the baffle 102 cannot contact each other.

[0027] The baffle 102 is placed in the baffle placement box 10, and under the action of the spring 101, the baffle 102 will be pushed to the baffle outlet 103, and the outermost baffle 102 will fall out of the baffle outlet 103; at the same time, when the outermost baffle 102 moves downward from the baffle outlet 103, the limit block 20 pushes the baffle 102 moving downward under the action of the driving device (the driving device can be a reciprocating motor), and in the process of the limit block 20 moving downward, the limit block 20 limits the movement of the baffle 102 to the baffle outlet 103, that is, it limits the other baffles 102 from falling out of the baffle outlet 103, ensuring that only one baffle 102 can fall out of the baffle outlet 102 at a time, and at this time, when the baffle 102 completely falls out of the baffle outlet 103, the limit block 20 moves upward again to complete a complete movement process. When the baffle 102 needs to be used again, the limiting block 20 can repeat the above steps again.

[0028] When the baffle 102 falls downward, the horizontal push rod 30 starts to move horizontally toward the baffle 102. When the baffle 102 falls completely, the push rod 30 contacts the baffle 102 horizontally and pushes the baffle 102 to contact the insulation layer 501 of the insulation pipe 50. Under the thrust of the push rod 30 and the viscosity of the insulation layer 501, when the push rod 30 is reset, the baffle 102 will be firmly adhered to the insulation layer 501 of the insulation pipe 50, completing the sealing of the insulation layer 501 of the insulation pipe 50. The insulation layer sealing mechanism utilizes the up and down movement of the limit block 20 and the horizontal movement of the push rod 30 to complete the sealing of the insulation layer 501 of the insulation pipe 50, which is quick and simple, does not require a lot of manpower to seal the insulation layer 501 of the insulation pipe 50, and greatly improves the sealing efficiency of the insulation layer 501 of the insulation pipe 50. After the baffle 102 falls, since it is very close to the insulation pipe 50, if the baffle 102 tilts, it will not affect the use of the baffle 102 (the baffle 102 is sleeved on the insulation pipe 50. At this time, when the baffle 102 moves from the insulation pipe 50, After the baffle is removed from the placement box 10, the baffle 102 will tilt when it is not under force, but the distance between the baffle 102 and the insulation tube 50 is very close. At this time, the baffle 102 is tilted against the insulation tube 50. Under the push of the push rod 30, the push rod 30 will come into contact with the tilted baffle 102. Under the action of the thrust, the tilted baffle 102 will be slowly pushed to a state perpendicular to the insulation tube 50 during the process of contacting the insulation layer 501. At this time, in this state, the entire baffle 102 will be in contact with the insulation layer 501.)

[0029] In a preferred embodiment, the limit block 20 is a triangular limit block.

[0030] When the limit block 20 pushes the baffle 102 to move out, the push rod 30 pushes the baffle 102 to move. At this time, if the limit block 20 is a rectangle or a square, the baffle 102 will always be in contact with the limit block 20 when moving, thereby increasing the force required for the push rod 30 to push the baffle 102 to move. At this time, the limit block 20 is set as a triangular limit block, and the hypotenuse of the triangular limit block is set downward. When the push rod 30 pushes the baffle 102 to move, the baffle will slowly stop contacting the limit block 20, thereby reducing the force required for the push rod 30 to push the baffle 102 to move.

[0031] Furthermore, the push rod includes a first push rod 301 and a second push rod 302 , and the first push rod 301 and the second push rod 302 are symmetrically arranged to push the baffle 102 to move out from under the baffle outlet 103 .

[0032] In order to ensure that the baffle 102 is evenly stressed, a first push rod 301 and a second push rod 302 are provided. The first push rod 301 and the second push rod 302 simultaneously apply thrust to the baffle 102 to ensure that the baffle 102 contacts the insulation layer 501 of the insulation pipe 50 in a vertical state.

[0033] In a preferred embodiment, the baffle 102 is a circular baffle.

[0034] In a specific application scenario, in order to better push the baffle 102 to contact the thermal insulation layer 501 , the baffle 102 is set as a circular baffle according to the shape of the thermal insulation layer 501 to increase the compactness of the thermal insulation layer 501 .

[0035] In another preferred embodiment, a circular ring is provided at the front end of the push rod 30, and the outer diameter of the circular ring is smaller than the outer diameter of the circular baffle, and the inner diameter of the circular ring is larger than the inner diameter of the circular baffle.

[0036] In order to balance the thrust of the push rod 30 on the baffle 102, a ring is set at the front end of the push rod 30, and when setting, the diameter of the ring should be smaller than the diameter of the ring baffle. If the diameter of the ring is too large, when the push rod 30 moves, the baffle 102 will pass through the circle in the middle of the ring, and the ring and the baffle 102 cannot contact each other, thereby failing to push the baffle 102 to move; if the diameter of the ring is too small, when the push rod 30 moves, the ring will pass through the circle in the middle of the baffle 102, and the ring and the baffle 102 cannot contact each other, thereby failing to push the baffle 102 to move. Therefore, when setting the ring baffle, the diameter of the ring baffle should be between the outer diameter and the inner diameter of the baffle 102.

[0037] In a preferred embodiment, an auxiliary platform 40 is further included, wherein the auxiliary platform 40 is provided with a concave groove 401, and a groove is provided on the concave groove 401. The auxiliary platform 40 is arranged below the baffle outlet 103, and the height of the auxiliary platform 40 is flush with the inner diameter of the outer protective tube of the insulation tube 50.

[0038] In order to ensure that the baffle 102 can just contact the insulation layer 501 after it falls, the auxiliary platform 40 is set below the baffle outlet 103. The height of the auxiliary platform 40 is flush with the inner radial direction of the outer protective tube of the insulation tube 50, and a concave groove 401 is set on the auxiliary platform 40. The shape of the concave groove 401 matches the shape of the baffle 102. When the baffle 102 falls, the baffle can better contact with the auxiliary platform 40, ensuring that the baffle 102 is pushed by the push rod 30 and contacts the insulation layer 501.

[0039] Specifically, a plurality of stacked concave groove plates 402 are arranged in the concave groove 401, the upper end surface of the concave groove plate 402 is provided with a card slot, and the lower end surface is provided with a protrusion, the protrusion is engaged with the groove, and the upper and lower adjacent concave groove plates are detachably connected to the card slot through the protrusion.

[0040] When in use, the diameters of the insulation tubes 50 of different sizes are different, that is, the vertical distances between the inner diameter of the outer protective tube of the insulation tube 50 and the auxiliary platform are different. At this time, the height of the auxiliary platform 40 needs to be changed according to the diameter of the insulation tube 50. At this time, in order to increase the applicability of the insulation layer sealing mechanism, a plurality of concave groove plates 402 are detachably arranged in the concave groove 401. When the diameter of the insulation tube 50 increases, the distance between the insulation tube 50 and the auxiliary platform decreases. At this time, a plurality of the concave groove plates 402 are removed to reduce the height of the auxiliary platform 40; conversely, when the diameter of the insulation tube 50 decreases, the distance between the insulation tube 50 and the auxiliary platform increases. At this time, a plurality of the concave groove plates 402 are added to increase the height of the auxiliary platform 40.

[0041] Operation steps: the groove opened on the concave groove 401 can be engaged with the protrusion provided on the lower end surface of the concave groove plate 402. At this time, the concave groove plate 402 is fixed on the auxiliary platform. In order to change the height of the auxiliary platform 40 and to avoid relative displacement of the two adjacent concave groove plates 402, the two adjacent concave groove plates 402 are connected to the groove using the protrusion; at the same time, the groove is set on the upper end surface of the concave groove plate 402 without changing the installation height of the baffle 102. If the protrusion is set on the upper end surface of the concave groove plate 402, the baffle 102 will contact the protrusion before it falls down, which is equivalent to lifting the baffle 102 in disguise. In this state, the baffle 102 cannot be accurately installed on the insulation pipe 50.

[0042] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
