Description

Technical Field

[0001] The present application relates to the technical field of cast iron pipe transportation, and in particular to a cast iron pipe lifter. Background Art

[0002] At present, cast iron pipes are pipes cast with cast iron, mainly used for water supply, drainage and gas transmission pipelines. In the production and processing of cast iron pipes, there are differences in position and height between each process and equipment. It is necessary to establish the transportation relationship of cast iron pipes between corresponding equipment in order to effectively and quickly complete the entire cast iron pipe production process. In related technologies, ropes are generally used to fix the pipe (cast iron pipe) on a transfer trolley, and then the transfer trolley is used to transport the pipe to a designated location.

[0003] Regarding the above-mentioned related technologies: it takes a long time to fix the pipeline on the transfer cart with ropes, and when the transfer cart transfers the pipeline to the designated location, the ropes need to be untied before the pipeline can be removed from the transfer cart. Therefore, there are problems such as inconvenience in fixing the pipeline on the transfer cart and inconvenience in removing the pipeline from the transfer cart, which leads to inconvenience in pipeline transportation. Utility Model Content

[0004] In order to facilitate the transportation of pipelines, the present application provides a cast iron pipe lift.

[0005] The present application provides a cast iron pipe lifter, which adopts the following technical solution:

[0006] A cast iron pipe lifter, comprising:

[0007] Mobile base;

[0008] A lifting mechanism, arranged on the mobile base;

[0009] A bracket, arranged on the lifting mechanism;

[0010] The clamping mechanism comprises a supporting member, a linkage assembly and two clamping members, wherein the supporting member is arranged on the bracket, the two clamping members are respectively arranged on the bracket and symmetrically distributed along the supporting member, the linkage assembly is respectively connected to the supporting member and the two clamping members, and when the pipeline is placed on the supporting member, the linkage assembly drives the two clamping members to clamp the pipeline.

[0011] By adopting the above technical solution, when it is necessary to transfer the pipeline, the pipeline is first placed on the supporting member, so that the linkage assembly drives the two clamping members to clamp the pipeline, so as to complete the fixing of the pipeline, and then the pipeline is transferred to the designated position by moving the base, and the lifting mechanism is started, and the lifting mechanism drives the bracket to lift and lower, so as to use the bracket to lift the pipeline to the designated height. At this time, the pipeline is lifted so that the pipeline no longer applies pressure to the supporting member, so that the linkage assembly no longer drives the two clamping members to clamp the pipeline, so that the pipeline is easily removed from the supporting member to complete the transfer of the pipeline.

[0012] Optionally, a through groove is vertically opened on the bracket, an elastic member is arranged in the through groove, one end of the supporting member is slidably inserted in the through groove and connected to the elastic member, the clamping member is slidably arranged on the bracket, the linkage assembly includes a rack, a gear and a screw rod, the rack is arranged on the supporting member, the screw rod is rotatably connected to the bracket, one end of the screw rod is provided with a first thread segment, the other end of the screw rod is provided with a second thread segment, the first thread segment and the second thread segment have opposite rotation directions, one clamping member is threadedly connected to the first thread segment, the other clamping member is threadedly connected to the second thread segment, the gear is coaxially connected to the screw rod and meshes with the rack.

[0013] By adopting the above technical solution, when the pipe is placed on the supporting member, the pipe applies pressure to the supporting member, so that the supporting member moves into the through groove, so as to apply pressure to the elastic member, so that the elastic member is compressed, and the supporting member drives the rack to move, so that the rack drives the gear to rotate, the gear drives the screw to rotate, and the screw drives the first thread segment and the second thread segment to rotate, so as to facilitate driving the two clamping members to approach each other to clamp the pipe, thereby facilitating the fixing of the pipe. When the pipe needs to be removed from the supporting member, the pipe is first lifted so that the pipe no longer applies pressure to the supporting member. At this time, the elastic member rebounds to push the supporting member to move out of the through groove, and the supporting member drives the rack to move, so that the rack drives the two clamping members to move away from each other through the gear and the screw, so that the two clamping members no longer clamp the pipe, so as to facilitate the removal of the pipe from the supporting member.

[0014] Optionally, a slide groove is opened on the bracket in the horizontal direction, the cross-section of the slide groove is dovetail-shaped, the screw rod is located in the slide groove, and one end of the clamping member is slidably inserted in the slide groove and fits against the inner wall of the slide groove.

[0015] By adopting the above technical solution, the cross-section of the slide groove is dovetail-shaped, so that the inner wall of the slide groove can limit the clamping piece, so that the clamping piece is not easy to fall out of the slide groove, and the screw rod is located in the slide groove, which can reduce the space occupied by the screw rod on the one hand, and enable the screw rod to cooperate with the inner wall of the slide groove on the other hand to limit the clamping piece, which is beneficial to improve the stability of the clamping piece during movement.

[0017] By adopting the above technical solution, the arc-shaped support plate and the arc-shaped clamping plate can better fit the pipe, and the gap between the arc-shaped support plate, the arc-shaped clamping plate and the pipe is reduced to a certain extent, which is conducive to improving the stability of the pipe after being fixed. In addition, the supporting seat can support the arc-shaped support plate, and the clamping seat can support the arc-shaped clamping plate, which further improves the stability of the arc-shaped support plate and the arc-shaped clamping plate in clamping the pipe.

[0018] Optionally, one end of the arc-shaped clamping plate away from the clamping seat is rotatably connected to a guide roller, and the axis of the guide roller is parallel to the axis of the arc-shaped clamping plate.

[0019] By adopting the above technical solution, the guide roller can guide the pipeline, making it difficult for the pipeline to collide with the arc-shaped clamping plate, and it is convenient to guide the pipeline between the two arc-shaped clamping plates, thereby facilitating the placement of the pipeline on the arc-shaped support plate.

[0020] Optionally, buffer pads are respectively provided on one side opposite to the two arc-shaped clamping plates and on one side of the arc-shaped supporting plate away from the supporting seat.

[0021] By adopting the above technical solution, the setting of the buffer pad makes it difficult for the pipeline and the arc-shaped support plate and the arc-shaped clamping plate to be damaged due to collision, which is beneficial to ensuring the integrity of the pipeline, and the buffer pad can fill the gap between the arc-shaped clamping plate and the pipeline and fill the gap between the arc-shaped support plate and the pipeline, which is beneficial to improve the stability of the pipeline after it is fixed.

[0022] Optionally, the buffer pad is provided with anti-slip grooves.

[0023] By adopting the above technical solution, the provision of anti-slip grooves can increase the friction between the pipeline and the buffer pad, thereby helping to reduce the possibility of sliding of the pipeline, and further helping to improve the stability of the pipeline after it is fixed.

[0024] Optionally, a reinforcing plate is respectively provided on one side of the two arc-shaped clamping plates facing away from each other, and one end of the reinforcing plate away from the arc-shaped clamping plate is fixedly connected to the clamping seat.

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The embodiment of the present application discloses a cast iron pipe lifting machine.

[0040] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] Reference Figure 1 A cast iron pipe lifter comprises a mobile base 1, a lifting mechanism 2, a bracket 3 and a clamping mechanism 4. The lifting mechanism 2 is mounted on the mobile base 1, the bracket 3 is mounted on the lifting mechanism 2, and the clamping mechanism 4 is mounted on the bracket 3. When the pipe needs to be transported, the clamping mechanism 4 is used to clamp the pipe, and then the mobile base 1 is moved to a designated position, and the lifting mechanism 2 is used to lift the bracket 3 to a designated height, so as to facilitate the transport of the pipe to the position to be placed.

[0042] Reference Figure 2 There are multiple clamping mechanisms 4, which are respectively mounted on the bracket 3, and the multiple clamping mechanisms 4 are grouped in pairs, and the two clamping mechanisms 4 in the same group can clamp the same pipe together, which is beneficial to improve the stability of the pipe after it is fixed. In this embodiment, there are four groups of clamping mechanisms 4.

[0043] Reference Figure 1 and Figure 3The clamping mechanism 4 includes a supporting member 41, a linkage assembly 42 and two clamping members 43. The supporting member 41 is arranged on the bracket 3, the two clamping members 43 are respectively slidably arranged on the bracket 3 and symmetrically distributed along the supporting member 41, and the supporting member 41 includes a supporting seat 411 and an arc-shaped supporting plate 412 fixedly connected to the supporting seat 411, and the clamping member 43 includes a clamping seat 431 and an arc-shaped clamping plate 432 fixedly connected to the clamping seat 431.

[0044] Reference Figure 3 The bracket 3 has a through slot 31 vertically formed on the upper side, and an elastic member 32 is disposed in the through slot 31. One end of the support seat 411 away from the arc-shaped support plate 412 is slidably inserted in the through slot 31 and fixedly connected to the elastic member 32. In this embodiment, the elastic member 32 is a spring.

[0045] When the pipe is placed on the support seat 411, the support seat 411 moves into the through slot 31 and applies pressure to the elastic member 32 to compress the elastic member 32, thereby facilitating buffering of the support seat 411. When the pipe needs to be removed from the support member 41, the pipe is first lifted so that the pipe no longer applies pressure to the support member 41. At this time, the elastic member 32 rebounds to push the support member 41 to move out of the through slot 31, thereby facilitating the return of the support member 41.

[0046] Reference Figure 3 The bracket 3 is provided with a slide groove 33 in the horizontal direction, the slide groove 33 is connected with the through groove 31, and one end of the clamping seat 431 is slidably inserted in the slide groove 33 and fits with the inner wall of the slide groove 33. In this embodiment, the cross section of the slide groove 33 is designed in a dovetail shape, so that the inner wall of the slide groove 33 can limit the clamping seat 431, so that the clamping seat 431 is not easy to be separated from the slide groove 33.

[0047] Reference Figure 3 and Figure 4 The linkage assembly 42 includes a rack 421, a gear 422 and a screw 423. The screw 423 is rotatably connected to the bracket 3 and is located in the slide groove 33, and one end of the screw 423 is provided with a first thread segment 4231, and the other end of the screw 423 is provided with a second thread segment 4232, and the first thread segment 4231 and the second thread segment 4232 have opposite rotation directions.

[0048] Reference Figure 4 One clamping seat 431 is threadedly connected to the first threaded segment 4231, and the other clamping seat 431 is threadedly connected to the second threaded segment 4232, so that when the screw rod 423 rotates, the two clamping seats 431 can be driven to move closer to or away from each other, thereby facilitating driving the two arc-shaped clamping plates 432 to move closer to or away from each other.

[0049] Reference Figure 3 and Figure 4The rack 421 is vertically fixedly connected to the support seat 411, the gear 422 is coaxially and fixedly connected to the screw rod 423, the gear 422 is located between the first thread segment 4231 and the second thread segment 4232, and the gear 422 and the rack 421 are meshed with each other. When the support seat 411 drives the rack 421 to move into the through slot 31, the rack 421 can drive the screw rod 423 to rotate through the gear 422, and the screw rod 423 drives the first thread segment 4231 and the second thread segment 4232 to rotate, so as to facilitate driving the two clamping seats 431 to approach each other. And when the support seat 411 drives the rack 421 to move out of the through slot 31, the two clamping seats 431 move away from each other.

[0050] Reference Figure 4 The end of the arc clamping plate 432 away from the clamping seat 431 is rotatably connected to a guide roller 4321, and the axis of the guide roller 4321 is parallel to the axis of the arc clamping plate 432. When the pipeline needs to be placed on the arc support plate 412, the guide roller 4321 can guide the pipeline so that the pipeline is not easy to collide with the arc clamping plate 432, and it is convenient to guide the pipeline between the two arc clamping plates 432, so as to facilitate the placement of the pipeline on the arc support plate 412.

[0051] The side opposite to the two arc-shaped clamping plates 432 and the side of the arc-shaped support plate 412 away from the support seat 411 are respectively fixedly connected with a buffer pad 44, which can buffer the pipeline so that the pipeline and the arc-shaped support plate 412 and the arc-shaped clamping plate 432 are not easily damaged due to collision, thereby facilitating the integrity of the pipeline. The buffer pad 44 can fill the gap between the arc-shaped clamping plate 432 and the pipeline and fill the gap between the arc-shaped support plate 412 and the pipeline, thereby facilitating the stability of the pipeline after being fixed.

[0052] The buffer pad 44 is provided with anti-slip grooves 441 , which can increase the friction between the pipeline and the buffer pad 44 , thereby helping to reduce the possibility of sliding of the pipeline, and further helping to improve the stability of the pipeline after being fixed.

[0053] Reference Figure 4 A reinforcing plate 433 is fixedly connected to the sides of the two arc-shaped clamping plates 432 that are away from each other, and one end of the reinforcing plate 433 away from the arc-shaped clamping plate 432 is fixedly connected to the clamping seat 431, so that the reinforcing plate 433 can support the arc-shaped clamping plate 432 to reduce the possibility of deformation of the arc-shaped clamping plate 432 due to excessive force, thereby facilitating the improvement of the stability of the arc-shaped clamping plate 432 when clamping the pipe.

[0054] Reference Figure 1 In this embodiment, the lifting mechanism 2 is a scissor-type lifting mechanism, so that the lifting mechanism 2 can be used to stably lift the bracket 3. A roller 11 is installed at the bottom of the mobile base 1 to facilitate the operator to push.

[0055] The implementation principle of the cast iron pipe lifting machine of the embodiment of the present application is as follows: when the pipe needs to be transported, the pipe is first placed on the support seat 411, so that the support seat 411 moves into the through groove 31 and applies pressure to the elastic member 32, the support seat 411 drives the rack 421 to move, the rack 421 drives the screw 423 to rotate through the gear 422, the screw 423 drives the first thread segment 4231 and the second thread segment 4232 to rotate, so as to drive the two clamping seats 431 to approach each other, so that the two arc-shaped clamping plates 432 clamp the pipe to fix the pipe. Then the mobile base 1 is used to transport the pipe to the specified position, and the lifting mechanism 2 is used to lift the pipe to the specified height so that the pipe contacts the position to be placed.

[0056] Next, the pipeline is lifted so that the pipeline no longer exerts pressure on the arc-shaped support plate 412. At this time, the elastic member 32 pushes the support seat 411 to return to its original position, so that the support seat 411 drives the two clamping seats 431 to move away from each other through the rack 421, the gear 422 and the screw rod 423, so that the two arc-shaped clamping plates 432 no longer clamp the pipeline, so that the pipeline can be placed in the position to be placed, and the transportation of the pipeline is completed.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
