Description

Technical Field

[0001] The utility model relates to the technical field of underground auxiliary welding devices, in particular to an underground pipeline network auxiliary welding device. Background Art

[0002] Underground pipeline networks refer to pipelines and their ancillary facilities such as water supply, drainage, gas, heat, electricity, communication, radio and television, and industry within the urban area. They are important infrastructure and "lifelines" to ensure the operation of the city. Usually, when connecting pipeline networks, an auxiliary welding device is needed to fix the pipeline networks so that they are opposite to each other, and then the pipeline networks are welded to be connected.

[0003] After retrieval, the Chinese patent discloses a laying device for underground pipeline networks (authorization publication number: CN217177662U), which includes a base, an auxiliary device, an adjusting device and a clamping device. The auxiliary device is arranged on the base, the adjusting device is arranged on the base, and the clamping device is arranged on the adjusting device; the auxiliary device includes a placing plate, a first electric push rod, a sliding plate and universal wheels. The placing plate is arranged on the base, the first electric push rod is arranged on the placing plate, the sliding plate is slidably connected to the first electric push rod, and the universal wheels are arranged on the sliding plate. The adjusting device includes a telescopic rod, a second electric push rod and a lifting plate. The clamping device includes a placing hole, a motor, a bidirectional threaded rod, a slide rail, a slider, a connecting column, a sliding wheel, a clamping plate and an anti-slip pad. The utility model belongs to the technical field of pipeline network laying, and specifically is an underground pipeline network laying device with high operation efficiency and reduced labor intensity.

[0004] In the actual application process of this patented technology, the pipeline network can be clamped and fixed to facilitate the subsequent welding connection of the pipeline network by the staff. However, in the use process, the above-mentioned scheme drives the bidirectional threaded rod through a motor to move the clamping device to clamp and fix the pipeline network. Since the force application point is above the clamping plate when moving the clamping plate, the phenomenon of insecure fixation will occur when fixing the pipeline network. At the same time, due to the different sizes of the pipeline networks, different fixtures are required. However, the above-mentioned scheme is inconvenient to replace the clamping plate, so the practicability of the device will be reduced. Summary of the Utility Model

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1-6 , the utility model provides an embodiment: an underground pipe network auxiliary welding device, including a base 1, four telescopic rods 2 are fixedly connected to the top of the base 1, an adjusting platform 3 is fixedly connected to the top end of the telescopic rod 2, the telescopic rod 2 is used to adjust the height of the adjusting platform 3, and adjusting mechanisms 4 are arranged inside the two sides of the adjusting platform 3. The adjusting mechanism 4 is sleeved with a first moving block 5 and a second moving block 6, and the adjusting mechanism 4 is used to adjust the position of the first moving block 5 and the second moving block 6. A card slot 10 is opened below the first moving block 5 and the second moving block 6, and a first clamp 7 and a second clamp 8 are arranged between the first moving block 5 and the second moving block 6. The first clamp 7 and the second clamp 8 are used to clamp the pipe network, and the first clamp 7 and the second clamp 8 are clamped with the first moving block 5 and the second moving block 6 through the card slot 10. A fixing mechanism 9 is arranged on the upper and lower sides of the first clamp 7;

[0027] The fixing mechanism 9 includes a fixing block 91, a rotating rod 92, a threaded rod 93 and a handle 94. The fixing block 91 is fixedly connected to the upper side of the first clamp 7. The rotating rod 92 is arranged between the fixing blocks 91. The rotating rod 92 is rotatably connected to the fixing block 91. One end of the threaded rod 93 passes through the rotating rod 92 and is threadedly connected to the rotating rod 92. The handle 94 is rotatably connected to the other end of the threaded rod 93. A through groove 12 is opened above the first clamp 7 and the second clamp 8.

[0028] Through the above technical solution, by setting up a fixing mechanism 9, by taking the connection between the rotating rod 92 and the threaded rod 93 as the center, the rotating handle 94 passes through the through grooves 12 on the first clamp 7 and the second clamp 8, and the handle 94 is rotated to the upper side of the second clamp 8. By pressing the handle 94, the handle 94 is made to contact with the second clamp 8, so that the first clamp 7 and the second clamp 8 can be more closely fitted, and the pipe network can be fixed more firmly.

[0029] Specifically, an insertion rod 11 is provided on one side of the first moving block 5 and the second moving block 6. One end of the insertion rod 11 passes through the second moving block 6 and the second clamp 8 and extends to the other side of the second moving block 6. The insertion rod 11 is slidably connected with the second moving block 6 and the second clamp 8.

[0030] Through the above technical solution, by pulling the insertion rod 11 to disengage the insertion rod 11 from inside the second moving block 6 and the second fixture 8, the second fixture 8 can be removed from inside the second moving block 6, so that the first fixture 7 and the second fixture 8 can be replaced, and thus pipe networks of different sizes can be clamped and fixed.

[0031] Specifically, a placement groove 15 is provided inside one end of the insertion rod 11. A spring 16 and a spherical steel ball 17 are movably connected inside the insertion rod 11. The spherical steel ball 17 is arranged above the spring 16, and one end of the spherical steel ball 17 penetrates through the inner wall of the insertion rod 11 and extends to its outside.

[0032] Through the above technical solution, by providing the spring 16 and the spherical steel ball 17, the spring force of the spring 16 itself can push the spherical steel ball 17 to always be located outside the insertion rod 11, which can prevent the insertion rod 11 from falling off from inside the second moving block 6 and the second fixture 8 due to the shaking of the device during operation.

[0033] Specifically, rubber pads 13 are provided on both sides of the other end of the handle 94, and the rubber pads 13 are fixedly connected to the handle 94.

[0034] Through the above technical solution, by providing the rubber pads 13, when the staff presses the handle 94, a soft contact can be formed between the staff's hand and the handle 94, which can increase the comfort of the staff. At the same time, the rubber pads 13 have an anti-slip effect, which can increase the friction between the staff's hand and the rubber pads 13 and prevent the staff's hand from slipping between the metal handle 94 during pressing.

[0035] Specifically, the threaded rod 93 and the handle 94 are eccentrically connected, and the end of the handle 94 is arc-shaped between the two contact surfaces of the second fixture 8.

[0036] Through the above technical solution, by setting the threaded rod 93 and the handle 94 to be eccentrically connected, by changing the angle of the handle 94, the distance of the threaded rod 93 can be shortened, so that the handle 94 abuts against the second fixture 8, thereby making the first fixture 7 and the second fixture 8 fit more closely. By setting the end of the handle 94 to be arc-shaped between the two contact surfaces of the second fixture 8, when the staff presses the handle 94, the contact surface between the handle 94 and the second fixture 8 can be easily flipped.

[0037] Specifically, a lifting rope 14 is fixedly connected to the other end of the insertion rod 11, the other end of the lifting rope 14 is fixedly connected to the second moving block 6, the length of the lifting rope 14 is greater than the length of the insertion rod 11, and one end of the insertion rod 11 is a cone.

[0038] Through the above technical solution, by setting the suspension rope 14, it can prevent the loss of the insertion rod 11 caused by the staff's mistake when pulling out the insertion rod 11. By setting one end of the insertion rod 11 as a cone, under the guiding effect of the cone, the staff can easily penetrate the insertion rod 11 through the second moving block 6 and the second fixture 8.

[0039] Working principle: When in use, first select a suitable fixture according to the size of the pipe network. Then, by pulling the insertion rod 11, when the spherical steel ball 17 on the insertion rod 11 abuts against the second moving block 6, under the action of pressure, the spherical steel ball 17 will overcome the elastic force of the spring 16 and return to the inside of the insertion rod 11, disengaging the insertion rod 11 from the inside of the second moving block 6 and the second fixture 8. Then, take out the second fixture 8 from the inside of the second moving block 6, install a new fixture, and just penetrate the insertion rod 11 through the second moving block 6 and the second fixture 8. When it is necessary to clamp and fix the pipe network, start the adjusting mechanism 4 to drive the first moving block 5 and the second moving block 6 to move, so that the first fixture 7 and the second fixture 8 clamp the pipe network. Then, with the connection point of the rotating rod 92 and the threaded rod 93 as the center, rotate the handle 94 through the through slot 12 on the first fixture 7 and the second fixture 8, and rotate the handle 94 to the upper side of the second fixture 8. By pressing the handle 94, under the action of the eccentric connection between the threaded rod 93 and the handle 94, the handle 94 abuts against the second fixture 8, so that the first fixture 7 and the second fixture 8 can fit more closely and fix the pipe network more firmly.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
