Description

Technical Field

[0001] This utility model relates to the technical field of large tubular product manufacturing equipment, and in particular to a split-type pipe jacking machine that is easy to assemble and disassemble. Background Technology

[0002] A pipe jacking machine is a specialized piece of equipment that propels a pipe in one direction. In the production of large tubular products, it uses a matching pipe jacking device to precisely eject the finished tubular product from the processing workshop. It controls the jacking speed and force through stable power output, ensuring uniform force distribution on the tubular product during ejection and preventing deformation or damage due to external impact. This equipment is adaptable to tubular products of different specifications, efficiently connecting production and subsequent transfer processes, significantly improving the production flow efficiency of large tubular products, and is an important piece of equipment for achieving automated output of tubular products in industrial production.

[0003] When the pipe jacking machine pushes the tubular product, some of the tubular products are longer than the range of existing pipe jacking rods. The existing pipe jacking rods will not be able to meet the pushing requirements. In this case, in order to ensure production continuity, the factory needs to purchase additional pipe jacking rods of other specifications and lengths, which increases the equipment procurement cost. Utility Model Content

[0004] The purpose of this invention is to address the problem that the existing pipe jacking rods cannot meet the jacking requirements for the length of some tubular products, which leads to factories needing to purchase pipe jacking rods of other specifications and lengths, thereby increasing the cost of producing large tubular products. Therefore, this invention proposes a modular pipe jacking machine that is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular pipe jacking machine that is easy to assemble and disassemble, comprising a modular pipe jacking assembly, a parking frame, and a pushing assembly. The modular pipe jacking assembly is slidably connected inside the parking frame. The driving end of the pushing assembly is connected to one side of the modular pipe jacking assembly. The modular pipe jacking assembly includes a first jacking pipe and several second jacking pipes. A transmission rack is fixedly connected to the outer side of the first jacking pipe and the several second jacking pipes. A first limiting rod is fixedly connected to the center of the first jacking pipe. Several extension rods are sequentially threaded to one end of the first limiting rod. A limiting frame is fixedly connected inside the second jacking pipe. The extension rods movably pass through the center of the limiting frame. The other end of one of the extension rods is threadedly connected to the second limiting rod.

[0006] Preferably, the parking rack includes a first support frame and several parking rings, with the several parking rings fixedly connected to one side of the first support frame.

[0007] Preferably, the inner side of the parking ring is provided with a plurality of mounting slots, and the interior of the plurality of mounting slots is rotatably connected to rollers.

[0008] Preferably, the pushing component includes a second support frame, a drive motor, a speed changer, and a drive gear. The drive motor is fixedly installed at one end of the second support frame. The output end of the drive motor is connected to the input end of the speed changer. The output end of the speed changer is fixedly connected to the center of the drive gear. The drive gear meshes with the transmission rack.

[0009] Preferably, the outer sides of the first limiting rod, the extension rod, and the second limiting rod are symmetrically fixedly connected with limiting blocks.

[0010] Preferably, a retaining ring is fixedly connected to the outer side of the second limiting rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by calculating and selecting the appropriate number of No. 2 top material pipes and extension rods, the extension rods are sequentially threaded to one end of the No. 1 limiting rod. Then, the No. 2 top material pipes are installed, so that the extension rods can move through the inside of the limiting frame. The limiting block and the limiting frame cooperate with each other to ensure that the No. 1 top material pipe and several No. 2 top material pipes are aligned. Then, the No. 2 limiting rod is installed to complete the length adjustment of the assembled top pipe assembly. The above assembly method is time-saving, which can shorten the time required for disassembly and assembly, and can adjust the length according to production needs, thereby reducing the equipment cost of the factory.

[0012] 2. In this invention, the rollers installed inside the mounting groove of the parking rack are in close contact with the outer side of the assembled pipe jacking assembly. During the sliding process of the assembly, the rollers not only provide support but also provide a certain amount of transmission assistance through their own rotation. This transmission effect can effectively reduce the frictional resistance between the assembled pipe jacking assembly and the parking rack, making the assembly slide more smoothly.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide 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 present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a modular pipe jacking machine that is easy to assemble and disassemble, including a modular pipe jacking assembly 1, a parking frame 2, and a pushing assembly 3. The modular pipe jacking assembly 1 is slidably connected inside the parking frame 2. The driving end of the pushing assembly 3 is connected to one side of the modular pipe jacking assembly 1. The modular pipe jacking assembly 1 includes a first jacking pipe 11 and several second jacking pipes 12. A transmission rack 13 is fixedly connected to the outer side of the first jacking pipe 11 and the several second jacking pipes 12. A first limiting rod 111 is fixedly connected to the center of the first jacking pipe 11. Several extension rods 112 are sequentially threaded to one end of the first limiting rod 111. A limiting frame 121 is fixedly connected inside the second jacking pipes 12. A rod 112 extends through the center of the limiting frame 121. The other end of an extension rod 112 is threaded to a second limiting rod 113. The pushing assembly 3 includes a second support frame 31, a drive motor 32, a speed changer 33, and a drive gear 34. The drive motor 32 is fixedly installed at one end of the second support frame 31. The output end of the drive motor 32 is connected to the input end of the speed changer 33. The output end of the speed changer 33 is fixedly connected to the center of the drive gear 34. The drive gear 34 meshes with the transmission rack 13. Limiting blocks 114 are symmetrically fixedly connected to the outer sides of the first limiting rod 111, the extension rod 112, and the second limiting rod 113. A retaining ring 115 is fixedly connected to the outer side of the second limiting rod 113.

[0018] The specific settings and functions of this embodiment are described in detail below. When it is necessary to adjust the length of the assembled jacking pipe assembly 1, the corresponding number of second-stage jacking pipes 12 and extension rods 112 are selected by calculation. The extension rods 112 are sequentially threaded to one end of the first-stage limiting rod 111. Then, the second-stage jacking pipes 12 are installed, so that the extension rods 112 can move through the interior of the limiting frame 121. The limiting block 114 cooperates with the limiting frame 121 to ensure that the first-stage jacking pipe 11 and several second-stage jacking pipes 12 are aligned, thereby making the transmission racks 13 mutually aligned. After assembly, the second limiting rod 113 is installed to complete the length adjustment of the assembled pipe jacking assembly 1. The above assembly method is time-saving, which can shorten the time required for disassembly and assembly, and can adjust the length according to production needs, reducing the equipment cost of the factory. When it is necessary to perform pipe jacking operation on the tubular product, the drive motor 32 drives the speed changer 33 to work, the speed changer 33 drives the drive gear 34 to rotate, the drive gear 34 meshes with the transmission rack 13, driving the assembled pipe jacking assembly 1 to move and push the tubular product out from the inside of the working area.

[0019] Example 2: Figure 1 - Figure 4 As shown, the modular pipe jacking machine of this utility model, which is easy to assemble and disassemble, includes a modular pipe jacking assembly 1, a parking frame 2, and a pushing assembly 3. The modular pipe jacking assembly 1 is slidably connected inside the parking frame 2. The driving end of the pushing assembly 3 is connected to one side of the modular pipe jacking assembly 1. The modular pipe jacking assembly 1 includes a first jacking pipe 11 and several second jacking pipes 12. A transmission rack 13 is fixedly connected to the outer side of the first jacking pipe 11 and the several second jacking pipes 12. A first limiting rod 111 is fixedly connected to the center of the first jacking pipe 11. One end of 111 is connected to several extension rods 112 in sequence by threads. The inside of the second top material tube 12 is fixedly connected to a limit frame 121. The extension rods 112 move through the center of the limit frame 121. The other end of one extension rod 112 is connected to a second limit rod 113 by threads. The parking frame 2 includes a first support frame 21 and several parking rings 22. The several parking rings 22 are fixedly connected to one side of the first support frame 21. Several mounting grooves 221 are opened on the inner side of the parking rings 22. Rollers 222 are rotatably connected inside the several mounting grooves 221.

[0020] The overall effect of this embodiment is that when the assembled pipe jacking assembly 1 slides on the parking frame 2, the rollers 222 installed inside the mounting groove 221 of the parking frame 2 will make close contact with the outer side of the assembled pipe jacking assembly 1. During the sliding process, the rollers 222 not only provide support but also provide a certain amount of transmission assistance through their own rotation. This transmission effect can effectively reduce the frictional resistance between the assembled pipe jacking assembly 1 and the parking frame 2, making the assembly slide more smoothly. There is no need to use a high-power drive assembly to drive the movement of the assembled pipe jacking assembly 1; only a lower-power drive device is required. This reduces equipment energy consumption and significantly reduces the procurement, installation, and maintenance costs of high-power drive assemblies, further reducing the overall equipment cost.

[0021] The usage method and working principle of this device are as follows: When it is necessary to adjust the length of the assembled pipe jacking assembly 1, the corresponding number of No. 2 jacking pipes 12 and extension rods 112 are selected by calculation. The extension rods 112 are then threaded to one end of the No. 1 limiting rod 111. Then, the No. 2 jacking pipes 12 are installed, so that the extension rods 112 can move through the inside of the limiting frame 121. The limiting block 114 cooperates with the limiting frame 121 to ensure that the No. 1 jacking pipe 11 and several No. 2 jacking pipes 12 are aligned, thereby aligning the transmission racks 13. Then, the No. 2 limiting rods 113 are installed to complete the length adjustment of the assembled pipe jacking assembly 1.

[0022] When it is necessary to perform a pipe jacking operation on the tubular product, the drive motor 32 drives the speed changer 33 to work, the speed changer 33 drives the drive gear 34 to rotate, the drive gear 34 meshes with the transmission rack 13, and drives the assembled pipe jacking assembly 1 to move, pushing the tubular product out from the inside of the working area.

[0023] When the assembled pipe jacking assembly 1 slides on the parking frame 2, the rollers 222 installed inside the mounting groove 221 of the parking frame 2 will make close contact with the outer side of the assembled pipe jacking assembly 1. During the sliding process of the assembly, the rollers 222 not only play a supporting role, but also provide a certain amount of transmission assistance through their own rotation.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
