Description

Technical Field

[0001] The utility model relates to the technical field of PE pipeline installation, in particular to a PE pipeline hot-melt connection and fixing device. Background Art

[0002] PE pipe generally refers to polyethylene pipe, which is widely used in various fields. Among them, water supply pipe and gas pipe are its two largest application markets. During the use of PE pipe, in order to meet the installation requirements, multiple sections of PE pipe need to be hot-melt welded. Hot-melt connection refers to a connection method between non-metal and non-metal after heating to the (liquid) melting point. It is widely used in the connection of new pipes and fittings such as PP-R pipe, PB pipe, PE-RT pipe, metal composite pipe, curved elastic vector, aluminum alloy lined plastic composite pipeline system, etc.

[0003] The existing hot melt connection device is not good for operating products of different lengths. When the length is too long, the rear end cannot be supported, so that when the hot melt connection is performed, the connection will be lifted, resulting in the misalignment of the hot melt connection. Generally, the staff will hold it with their hands all the time, but if they hold it with their hands for a long time, they will become tired, resulting in the misalignment of the connection. Utility Model Content

[0004] The utility model aims to provide a PE pipe hot-melt connection fixing device, aiming to solve the problem that the existing hot-melt connection device is not easy to operate for products of different lengths. When the length is too long, the rear end cannot be supported, so that when the hot-melt connection is performed, the connection will be warped, resulting in the problem of hot-melt connection misalignment.

[0005] To achieve the above object, the utility model adopts the following technical solution: the PE pipe hot-melt connection fixing device comprises a bottom plate, a support column is fixedly provided on the top of the bottom plate, a hot-melt machine is fixedly provided on the support column, and the left and right sides of the hot-melt machine are respectively connected to pipes;

[0006] Two driving mechanisms are symmetrically arranged above the bottom plate, and a first clamping assembly is arranged on opposite sides of the two driving mechanisms. The first clamping assembly is transmission-connected to the driving mechanism, and the driving mechanism is used to drive the first clamping assembly to contract and extend;

[0007] A second clamping assembly is provided on the opposite side of the two driving mechanisms. The second clamping assembly is transmission-connected to the driving mechanism by two telescopic members spaced front and back and capable of driving the second clamping assembly to move left and right. The first clamping assembly and the second clamping assembly cooperate with each other to clamp the front and rear ends of the pipe.

[0008] Preferably, the first clamping assembly includes a plurality of first clamping wheels and a moving block. A groove with an opening facing the center of the circle is formed in the moving block. A first spring is fixedly arranged in the groove. The other end of the first spring is fixedly provided with a plug block which is slidably inserted into the groove. The plug block is rotatably connected to the first clamping wheel.

[0009] Limit plates are arranged on both the left and right sides of the hot melt machine. The limit plates are in transmission connection with the driving mechanism and are slidably sleeved on the moving block.

[0010] Preferably, a storage frame is arranged on one side of the driving mechanism close to the telescopic member. The storage frame is in transmission connection with the telescopic member. A connecting column is fixedly arranged below the storage frame, and the connecting column is fixedly connected to the bottom plate.

[0011] Preferably, the driving mechanism includes a first gear, a second gear and a handle. The second gear is arranged above the first gear and meshes with the first gear. The handle passes through the second gear and is rotatably connected to the limit plate through a bearing, and the handle is fixedly connected to the second gear;

[0012] A threaded rib is fixedly arranged on one side of the first gear close to the moving block. The moving block is slidably arranged in the threaded rib. When the threaded rib rotates, it is used to adjust the retracting and extending range of the moving block.

[0013] Preferably, moving frames are arranged on the opposite sides of the two driving mechanisms. The moving frames are in transmission connection with the other end of the telescopic member. A storage cavity is arranged inside the moving frames, and the second clamping assembly is arranged in the storage cavity.

[0014] Preferably, the second clamping assembly includes a swing rod and a second spring installed in the storage cavity. Both the swing rod and the second spring are multiple. The swing rod is rotatably arranged in the storage cavity. One end of the second spring is fixedly arranged on the inner side wall of the storage cavity, and the other end of the second spring is fixedly connected to the outer side surface of the swing rod;

[0015] A second clamping wheel is rotatably arranged on the side of the swing rod away from the second spring. The multiple second clamping wheels cooperate with each other to clamp the pipeline.

[0016] Preferably, a vertical rod extending in the up and down direction is fixedly arranged at the top of the telescopic member. Two sliding holes which are spaced front and back and penetrate up and down are formed in the storage frame. A cross rod extending in the front and back direction is arranged above the storage frame. Both the vertical rods pass through the sliding holes and are fixedly connected to the cross rod. When the cross rod moves left and right in the sliding holes, the telescopic member can be driven to extend or contract.

[0017] Preferably, through holes that correspond to each other left and right are formed in the limiting plate, the moving frame, and the storage frame, and the pipeline is inserted into the through holes.

[0018] The beneficial effects are as follows: 1. Through the mutual cooperation of the first clamping assembly and the second clamping assembly, when the pipeline is too long, the cross bar can be toggled, and under the drive of the telescopic member, the second clamping assembly extends to one side for use. In this way, when the too-long pipeline is subjected to hot melt connection, it is not necessary to keep holding it by hand all the time to maintain stable hot melt connection, improving the effect of hot melt connection.

[0019] 2. In both the first clamping assembly and the second clamping assembly, rotatable rollers are used to clamp the pipeline, so that during the clamping process, the staff can manually rotate the pipeline according to requirements for hot melt connection, improving the uniformity of the hot melt connection of the pipeline.

[0020] 3. Through the settings of the first spring and the second spring, during the clamping process, pipelines of different sizes can be adapted, thus playing a role in improving the applicability. Description of the Drawings

Detailed implementation manners

[0028] The following further describes the detailed implementation manners of the present utility model in conjunction with the accompanying drawings.

[0029] As Figures 1-6 shown, a fixing device for hot melt connection of PE pipelines includes a bottom plate 1. By clamping and fixing two pipelines 4 respectively, and then under the action of the hot melt machine 3, the two pipelines 4 can be hot melt connected. Specifically, a support column 20 is fixedly arranged on the top of the bottom plate 1. The setting of the support column 20 enables the support of the hot melt machine 3 so that the hot melt machine 3 can perform hot melt connection on the two pipelines 4. The hot melt machine 3 is fixedly arranged on the support column 20. The left and right sides of the hot melt machine 3 are respectively connected with a pipeline 4. Inserting the pipeline 4 into the hot melt machine 3 can perform hot melting on the connection part of the pipeline 4 and then connect them to each other.

[0030] Above the bottom plate 1, there are two driving mechanisms 5 arranged symmetrically left and right. On the opposite sides of the two driving mechanisms 5, there is a first clamping assembly 2 respectively. The first clamping assembly 2 is in transmission connection with the driving mechanism 5. The driving mechanism 5 is used to drive the first clamping assembly 2 to contract and extend. After the driving mechanism 5 is started, it can drive a plurality of first clamping assemblies 2 to contract inward simultaneously, so as to adjust the clamping size of the plurality of first clamping assemblies 2, so as to be applicable to pipelines 4 of different sizes and improve the applicability.

[0031] The first clamping assembly 2 uses a rotatable first clamping wheel 201 to clamp the pipe 4, so that during the clamping process, the staff can manually rotate the pipe 4 for hot-melt connection according to needs, which improves the uniformity of the hot-melt connection of the pipe 4. Specifically, the first clamping assembly 2 includes a plurality of first clamping wheels 201 and a moving block 202. The moving block 202 is provided with a groove with an opening toward the center of the circle, and a first spring 18 is fixedly provided in the groove. The other end of the first spring 18 is fixedly provided with a plug-in block 8 (the plug-in block 8 is composed of two parts, one of which is Inserted in the groove of the moving block 202, and the other part is arranged at both ends of the first clamping wheel 201, and is rotatably connected to the two ends of the first clamping wheel 201, so that it can support the first clamping wheel 201), the plug-in block 8 is slidably inserted in the groove, the plug-in block 8 is rotatably connected to the first clamping wheel 201, a blocking ring is fixed on the edge of the groove, and the end of the plug-in block 8 away from the first clamping wheel 201 is fixed with a clamping block adapted to the blocking ring, the clamping block slides in the groove, so that the plug-in block 8 will not slip out of the groove.

[0032] Limiting plates 10 are provided on both sides of the hot melt machine 3. The limiting plates 10 are transmission connected to the driving mechanism 5. The limiting plates 10 are slidably mounted on the moving block 202. The limiting plates 10 can limit the moving block 202 to prevent the moving block 202 from being displaced or falling.

[0033] A second clamping assembly 6 is provided on the opposite side of the two driving mechanisms 5. The second clamping assembly 6 and the driving mechanism 5 are transmission-connected with two telescopic members 7 which are spaced front and back and can drive the second clamping assembly 6 to move left and right. The first clamping assembly 2 and the second clamping assembly 6 cooperate with each other to clamp the front and rear ends of the pipe 4. After extending, the second clamping assembly 6 can clamp the rear end of the pipe 4 so that the pipe 4 will not warp up, and there is no need for the staff to manually support the hot-melt connection, which reduces the labor intensity of the staff and improves the connection effect of the pipe 4.

[0034] A storage frame 11 is provided on one side of the driving mechanism 5 close to the telescopic member 7. The storage frame 11 is transmission-connected to the telescopic member 7 (the telescopic member 7 is a scissor-type telescopic frame structure). A connecting column 12 is fixedly provided below the storage frame 11. The connecting column 12 is fixedly connected to the base plate 1. Under the action of the telescopic member 7, the movable frame 13 can be extended and retracted.

[0035] When not extended for use, the movable frame 13 is located inside the storage frame 11 so that the stacked movable frame 13 can be stored. Specifically, the driving mechanism 5 includes a first gear 501, a second gear 502 and a handle 503. The second gear 502 is arranged at the upper end of the first gear 501, and the second gear 502 is meshed with the first gear 501. Since the second gear 502 is meshed with the first gear 501, the first gear 501 can be driven to rotate. The handle 503 passes through the second gear 502 and is rotatably connected to the limit plate 10 through a bearing, and the handle 503 is fixedly connected to the second gear 502. Manually rotating the handle 503 can drive the second gear 502 to rotate.

[0036] A threaded protrusion 9 (the threaded protrusion 9 is a spiral structure) is fixedly provided on one side of the first gear 501 close to the moving block 202. The moving block 202 is slidably arranged in the threaded protrusion 9. When the threaded protrusion 9 rotates, it is used to adjust the retraction and extension range of the moving block 202. Since the threaded protrusion 9 on the first gear 501 is slidably connected with the moving block 202, when the threaded protrusion 9 rotates, it can drive the moving block 202 to extend or retract inward or outward.

[0037] A moving frame 13 is provided on the opposite side of the two driving mechanisms 5. The moving frame 13 is transmission-connected to the other end of the telescopic member 7. A storage cavity 14 is provided inside the moving frame 13. The second clamping assembly 6 is arranged in the storage cavity 14. The moving frame 13 can be extended away from the storage frame 11 under the action of the telescopic member 7, and the storage cavity 14 on the moving frame 13 can also have a storage effect on the swing rod 601.

[0038] The second clamping assembly 6 includes a swing rod 601 (the swing rod 601 is an elastic rod) and a second spring 602 installed in the storage chamber 14. There are multiple swing rods 601 and second springs 602. The swing rod 601 is rotatably arranged in the storage chamber 14. One end of the second spring 602 is fixed on the inner wall of the storage chamber 14, and the other end of the second spring 602 is fixedly connected to the outer side surface of the swing rod 601. When the pipe 4 is thicker, the second spring 602 can be squeezed by the swing rod 601. If there is no pipe 4, it can be restored to its original state under the action of the second spring 602 for next use.

[0039] A second clamping wheel 15 is rotatably provided on one side of the swing rod 601 away from the second spring 602. Multiple second clamping wheels 15 cooperate with each other to clamp the pipe 4. The second clamping wheel 15 is attached to the outer side of the pipe 4, so that rotating the pipe 4 can drive the second clamping wheel 15 to rotate.

[0040] When adjusting the length of the telescopic member 7, just pull the cross bar 17. Specifically, a vertical bar 16 extending in the up and down direction is fixedly provided at the top of the telescopic member 7. Two sliding holes that are spaced front and back and penetrate up and down are formed in the storage frame 11. A cross bar 17 extending in the front and back direction is provided above the storage frame 11. Both vertical bars 16 pass through the sliding holes and are fixedly connected to the cross bar 17. When the cross bar 17 moves left and right in the sliding holes, it can drive the telescopic member 7 to extend or contract. When the cross bar 17 moves along the sliding holes and approaches the first gear 501, the telescopic member 7 contracts. When the cross bar 17 slides along the sliding holes and moves away from the first gear 501, the telescopic member 7 can be extended to adjust the extension amount of the moving frame 13.

[0041] Through holes that correspond to each other left and right are formed in the limiting plate 10, the moving frame 13, and the storage frame 11, and the pipe 4 is inserted into the through holes.

[0042] Working principle: As shown in Figure 1- Figure 6 As shown, before use, first move the cross bar 17, so that the cross bar 17 moves along the sliding holes. When it approaches the first gear 501, the telescopic member 7 contracts. When the cross bar 17 slides along the sliding holes and moves away from the first gear 501, the telescopic member 7 can be extended to adjust the extension amount of the moving frame 13.

[0043] After the moving frame 13 extends out of the storage frame 11 and the length is suitable for clamping and supporting the pipe 4 to be hot melt connected, the two pipes 4 are respectively inserted into the through holes and pass through the gap formed by the first clamping wheel 201 and the second clamping wheel 15. Through the arrangement of the first spring 18 and the second spring 602, different sizes of pipes 4 can be adapted during the clamping process, thus playing a role in improving the applicability.

[0044] After clamping, the pipe 4 can be inserted into the hot melt machine 3, and the connection part of the pipe 4 can be hot melted and then connected to each other.

[0045] As shown in the figure Figure 2 and Figure 3 , if the pipe 4 is too large or too small, the handle 503 can be manually rotated to drive the second gear 502 to rotate. Since the second gear 502 meshes with the first gear 501, the first gear 501 can be driven to rotate. Since the threaded rib 9 on the first gear 501 is slidably connected to the moving block 202, when the threaded rib 9 rotates, the moving block 202 can be driven to expand or contract inwards or outwards to adjust the size between multiple moving blocks 202, so as to adapt to pipes 4 that are too large or too small for use.
